Description

  The present invention relates to a toilet apparatus provided with a crushing unit that can crush sanitary goods. Specifically, a rotary blade member provided with a large number of rotary blades is used as a pulverization unit constituting the pulverization unit, and the pulverization unit can be efficiently pulverized by driving them while meshing each other. The toilet can be used even if it is removed.

  If sanitary products such as sanitary products are dumped directly in flush toilets after use, drainage pipes and the like may be clogged. For this reason, sanitary goods are usually dumped in a dedicated trash can installed in the toilet after use, or stored in a plastic bag etc. until the date of garbage collection and discarded as burning garbage.

  However, it is very convenient if sanitary goods can be discharged using a flush toilet (fixed toilet device) that is used daily. Recently, baby paper diapers such as toilet tissue paper, and adult diapers for nursing care, etc. have become widespread. It is very convenient if it can be processed using.

  Even in a portable simple toilet device used for nursing or nursing care, if this is a flush type, it is preferable that sanitary goods and the like can be processed in the same manner as the fixed toilet device.

  Among these, portable portable toilet devices are known in which a waste material is pulverized and then discharged (for example, Patent Document 1 and Patent Document 2).

JP 2000-8442 A Japanese Patent Laid-Open No. 2001-275858

  By the way, in the simple toilet apparatus disclosed by patent document 1 or patent document 2, all are using the stirring means as a means to process filth. By driving the agitating means installed in the reservoir part of the toilet, the filth is crushed and then discharged, but the sanitary goods including the above-mentioned paper diapers etc. should be crushed. Becomes difficult. This is because it is not sufficient to just stir the inside of the reservoir. Therefore, the technology employed in the portable simple toilet device cannot be directly transferred to the fixed toilet device.

  Moreover, since the stirring means etc. which are installed in a reservoir part are easy to get dirty, it is preferable to clean regularly on hygiene. In the above-described simple toilet device, the reservoir portion itself is narrow, so it is difficult to clean. Even when applied to a stationary toilet device, the agitation means is fixed to the toilet and cannot be easily cleaned.

  Of course, since the stirring means is installed in the toilet bowl, when the stirring means fails, it cannot be easily repaired, and the toilet cannot be used during repair. If possible, it is preferable that the toilet can be used as usual even if the stirring means is removed.

  Therefore, the present invention solves such a conventional problem, and in particular, sanitary articles including paper diapers and the like are reliably pulverized by using a pulverizing means having a structure in which two rotary blades are engaged with each other. The present invention proposes a toilet device that can be used as a normal toilet device even if the pulverization unit including the pulverizing means is removed from the toilet bowl.

In order to solve the above-described problem, a toilet apparatus according to the present invention described in claim 1 is:
A toilet whose bottom is a reservoir,
It is attached so as to cross the reservoir, and is composed of a crushing unit that is detachable from the toilet.
The crushing unit has crushing means composed of at least a pair of rotating blade members that mesh with each other, and an attachment member thereof,
The rotary blade member is composed of a plurality of rotary blades provided coaxially with a predetermined interval.

  In this invention, a crushing unit is attached so that it may block across the reservoir part of a toilet bowl. The pulverizing unit is composed of pulverizing means and its attachment member. The toilet is composed of an upper toilet part, a bottom toilet part, and an intermediate toilet part located therebetween. The intermediate toilet part is watertightly fixed to the upper toilet part and the bottom toilet part using a fixing member such as a screw. An intermediate toilet part is used as an attachment member of the crushing unit.

  The crushing means has at least first and second rotary blade members that mesh with each other. These rotary blade members are composed of a plurality of rotary blades provided coaxially with a predetermined interval. Driving means for the first and second rotary blade members are disposed on the outer peripheral surface of the attachment member. An alternative member can be attached to the crushing unit. Therefore, by attaching and fixing the intermediate toilet part between the upper toilet part and the bottom toilet part, the crushing means is rotatably provided in the reservoir part of the toilet bowl.

  The sanitary product dropped from the upper toilet part side is scraped between the first rotary blade member and the second rotary blade member, so that the sanitary product is crushed while being cut by the plurality of rotary blades. When a cross-cut blade is used as the rotary blade, it is pulverized in a state of being finely cut by the rotary blade.

  The pulverized sanitary article falls to the lower side (reservoir bottom) of the rotary blade member. Therefore, by flowing an appropriate amount of washing water from the upper toilet part side during or after the pulverization process, the crushed sanitary goods are discharged together with the washing water from the toilet outlet to the drain pipe (sewage pipe) side.

  When cleaning or repairing the crushing means, the entire intermediate toilet part is removed from the toilet bowl. Since the toilet cannot be used with the intermediate toilet part removed, an alternative member having the same shape as the intermediate toilet part is attached and fixed between the upper toilet part and the bottom toilet part. By doing so, it can be used as a normal flush toilet. The removed crushing unit is cleaned or repaired and then replaced with a replacement member. The alternative member is not equipped with a crushing means.

  Even if the toilet is not divided into three parts in this way, the crushing unit can be removed. For example, a mounting hole for mounting the crushing unit is provided on one side wall of the reservoir, and a support portion for supporting the crushing unit is provided on the other side wall. By crushing and fixing the crushing unit in a watertight manner from the mounting hole side, the crushing means can be installed in the pool portion so as to be rotatable.

  When removing the crushing unit, an alternative member (packing material) that closes the mounting hole is used. By using this alternative member, the toilet can be used as usual even when the crushing unit is removed.

  The toilet device can be applied to an ordinary fixed toilet device (flush toilet) and a portable simple toilet device.

  According to the present invention, a pulverizing unit including a pulverizing means in which rotating blades are engaged with each other can be detachably attached to a toilet, and an alternative member can be attached to a portion from which the pulverizing unit has been removed.

  According to this, sanitary goods including paper diapers and the like can be reliably pulverized, so that a special processing apparatus such as a sanitary goods processing apparatus can be eliminated. In addition, since the pulverizing unit including the pulverizing means can be removed from the toilet bowl, the pulverizing means can be easily cleaned and repaired, and the toilet can be used even with the pulverizing unit removed. Can be wiped away.

  Next, a preferred embodiment of the toilet apparatus according to the present invention will be described in detail with reference to the drawings.

  The toilet device according to the present invention can be used as an alternative or as a new installation for all currently used Western-style faucet toilet devices (fixed toilet devices), whether for home or business use. it can. In addition to the fixed toilet device, the portable toilet device can be used for nursing or nursing, and the present invention can be applied to the simple toilet device as long as it is a flush type.

  FIG. 1 shows a case where the toilet apparatus according to the present invention is applied to a fixed toilet apparatus. This toilet apparatus includes a Western-style toilet 100. The toilet 100 is a split-type toilet that is used by being divided and assembled into a plurality of parts, and includes an upper toilet 100A, a bottom toilet 100C, and an intermediate toilet 100B positioned therebetween. The toilet 100 is made of a plastic material or ceramics.

  The upper toilet part 100A has an opening, and the toilet seat 110 is located. 100 C of bottom toilet parts comprise the bottom part among the reservoir parts provided in a toilet bowl, and the intermediate toilet part 100B comprises a reservoir part.

  The upper toilet part 100A is a funnel-shaped cylinder whose both ends are open, the intermediate toilet part 100B is a cylinder whose both ends are opened, and the bottom toilet part 100C is a bottomed tubular body which is connected to a drain pipe. A trap outlet is provided.

  The plurality of toilet parts 100A to 100C are attached and fixed in a watertight manner by fixing means such as screws. Therefore, a fixing flange 102 is integrally formed on the lower end surface of the upper toilet portion 100A, and a flange 104 is also integrally formed on the upper end surface of the intermediate toilet portion 100B so as to face the flange 102. Similarly, corresponding flanges 106 and 108 are also provided between the intermediate toilet part 100B and the bottom toilet part 100C, respectively, and in the assembled state as shown in FIG. Do not attach) and fix each other in a watertight manner.

  Since the toilet 100 is used in the assembled state, as shown in FIG. 2, the flush water tank (flush tank) 122 supplied to the toilet 100 and the toilet 100 are installed in a non-contact state. Therefore, the flush tank 122 is fixed using the mounting base 124.

  In the present invention, the toilet unit 100 includes a crushing unit 60. As shown in FIG. 3, the pulverizing unit 60 includes pulverizing means 70 and its attachment member 80. As shown in FIG. 4, the crushing means 70 includes first and second rotary blade members 70 </ b> A and 70 </ b> B arranged in meshing relation with each other, and both ends thereof are rotatably fixed to the attachment member 80. In this example, the intermediate toilet part 100B is used as the attachment member 80. Accordingly, the first and second rotary blade members 70A and 70B are arranged so as to cross the intermediate toilet part 100B.

  As shown in FIG. 4, in the first rotary blade member 70A, a plurality of rotary blades 74 (74a, 74b...) Are arranged on the rotary shaft 70a with a predetermined interval. The second rotary blade member 70B is similarly configured, and is configured by arranging the same or one more rotary blades 76 (76a, 76b,...) On the rotary shaft 70b. Are arranged in a staggered manner. The size of the rotary blades 74 and 76, the number to be installed, and the like vary depending on the accommodation space of the crushing unit 60.

  In the illustrated state of FIG. 4, when using the intermediate toilet part 100B whose upper end side is rectangular and whose lower end side is substantially horseshoe-shaped, each rotary blade member 70A, 70B is configured. In FIG. 4, it is a case where it comprises with three rotary blades.

  Here, the rotary blades 74 and 76 adjacent to each other are not arranged in a state where they are completely meshed with each other. For example, sanitary products such as sanitary products and disposable diapers may be considered in addition to filth and toilet paper. Since these objects to be crushed have a certain thickness, in order to make it easy to cut sanitary articles, the thicknesses of these rotating objects 74 and 76 are considered as shown in FIGS. 3 and 4 in consideration of these thicknesses. An interval and a facing distance to the rotation shafts 70a and 70b are set.

  As the rotary blades 74 and 76, a disk-like rotary blade having a blade-like tip, or an elliptical rotary blade having a sharp tip on its peripheral surface (so-called cross-cut blade) can be used. . The latter rotary blade can be cut into strips more finely than the former rotary blade.

  FIG. 6 shows an example of the latter rotary blade 74. In this example, a pair of pointed blades 75a are provided at positions facing each other by approximately 180 °. The pointed blade 75a has a blade shape such that the end surfaces of the pointed blade 75a face each other in the rotation direction a. The other rotary blade 76 also has a pointed blade 77a having the same structure (see FIGS. 3 and 4).

  As shown in FIGS. 3 and 4, when a plurality of rotary blades 74 are attached to the rotary shaft 70a, the attachment positions of the pointed blades 75a are sequentially shifted by a predetermined angle (about 60 °) in rotational phase (attachment angle). Mounting is fixed. Even the other rotary blade 76 is attached and fixed to the rotary shaft 70b in a state where the rotational phase is sequentially shifted by a predetermined angle. Accordingly, the tip blades 75a and 77a are rotationally driven while maintaining a small clearance while the tip blades 75a and 77a face each other. Actually, the rotary blades 74 and 76 are not driven in a meshed state, but the rotary blades 74 and 76 mesh with each other when a pulverized object such as filth or sanitary goods is interposed. The object to be crushed can be finely cut.

  Although not shown, a scraping means for scraping an object to be ground toward the grinding means 70 can be disposed above the grinding means 70. The scraping means can be composed of a pair of scraping rotating members in which a plurality of rotating bodies having scraping blades are arranged.

  Further, a scraping means for scraping pulverized material entangled between the rotary blade 74 and the rotary blade 74 (rotary blades 76 and 76) can be provided below the rotary blade members 70A and 70B. As the scraping means, a plate body having comb teeth entering between the rotary blades can be used.

  In this example, as described above, the intermediate toilet part 100B is used as the attachment member 80 of the crushing means 70 described above. As shown in FIGS. 3 and 4, the intermediate toilet portion 100B is a cylindrical body having a horseshoe shape, and as shown in FIG. 4, the rotating shaft constituting the crushing means 70 across the left side wall 78a and the right side wall 78b. 70a and 70b are attached. Therefore, in this example, a concave portion 79a for attaching the rotary shaft is formed at a predetermined position of the left side wall 78a, and a through hole (attachment hole) 79b for attaching the rotary shaft is provided on the right side wall 78b facing the concave portion 79a. Drilled.

  A shaft supporting means 90 for rotating shafts 70a and 70b is fitted into the recess 79a. As shown in FIG. 4, the shaft support means 90 includes bearing portions 90a and 90b for the rotating shafts 70a and 70b, and a support member 90c. The support member 90c is a member that supports the bearing portions 90a and 90b in common, and is made of a material that can be watertightly attached to the left side wall 78a. In this example, it is formed of a relatively hard rubber material or plastic material, and by inserting the support member 90c into the mounting recess 79a, the left end side of the rotating shafts 70a, 70b is the left side wall 78a of the intermediate toilet 100B. Fixed to.

  The other end portions of the rotary shafts 70a and 70b are also supported by the shaft support means 92. The shaft support means 92 is also composed of bearing portions 92a and 92b for the rotating shafts 70a and 70b and a support member 92c. The support member 92c is a member that supports the bearing portions 92a and 92b in common, and is made of a material that can be watertightly attached to the attachment hole 79b of the right side wall 78b as in the case of the shaft support means 90. By fitting the support member 92c into the attachment mounting hole 79b, the right end side of the rotary shafts 70a and 70b is fixed to the right side wall 78b of the intermediate toilet part 100B. In this case, the support member 92c is fixed to the right side wall 78b by a fixing means such as a screw just in case.

  Drive means 130 for driving the rotation shafts 70a and 70b is provided outside the right side wall 78b, as shown in FIGS. Therefore, gears 97a and 97b that mesh with each other are attached to the respective rotary shafts 70a and 70b, and in this example, the rotational force from the drive motor 138 is transmitted via the pulley 132 attached to the one rotary shaft 70a. Is done. Therefore, the pulley 134 on the drive motor 138 side and the pulley 132 on the rotating shaft 70 a side are connected by the belt 136.

  The driving means 130 is covered with a rectangular case 150 so as not to be exposed to the outside. By concentrating the driving means 130 on the outer surface side of the right side wall 78b of the intermediate toilet part 100B in this way, the grinding means 70 including the attachment member 80 and the entire driving means 130 can be removed together with the intermediate toilet part 100B. Therefore, by removing the intermediate toilet unit 100B from the toilet body, it is possible to perform maintenance / inspection, replacement, repair, etc. of the driving means 130 as well as maintenance / inspection, replacement, repair of the crushing means 70.

In addition, when the intermediate toilet part 100B is removed from the toilet body in this way, the toilet 100 cannot be used. To eliminate this inconvenience,
As shown in FIG. 7, an auxiliary toilet part 140 without the crushing means 70 and the driving means 130 is prepared as an alternative member as an alternative member of the intermediate toilet part 100B.

  This auxiliary toilet part 140 has exactly the same external shape and size as the intermediate toilet part 100B, is composed of a horseshoe-shaped cylinder, and has mounting flanges 142 and 144 at the top and bottom thereof. Therefore, when the intermediate toilet part 100B is removed, the auxiliary toilet part 140 is installed and fixed as an alternative instead of the intermediate toilet part 100B (see FIG. 7). By doing so, there is no pulverization function for the object to be crushed, but since it can be used as a normal toilet, inconvenience in daily life is eliminated. If the auxiliary toilet part 140 is provided by a repair manufacturer or the like when the intermediate toilet part 100B is removed, the auxiliary toilet part 140 does not need to be provided on the user side.

  In the upper toilet part 100A, there is provided a dropping restriction cylinder 152 having a funnel shape and a lower opening end surface thereof having a substantially rectangular shape. By squeezing the lower opening surface of the drop restricting cylinder 152, sanitary articles dropped from the opening of the upper toilet part 100A fall to the center side of the crushing means 70, and sanitary articles can be efficiently crushed. It becomes like this. Since the wash water used in the toilet bowl is supplied from the upper toilet part 100A side, even if sanitary goods stick to the inner peripheral surface of the drop restriction cylinder 152, the pulverizing means 70 is washed with the wash water. Can be poured into the side.

  FIG. 8 shows an example of a control system 160 for driving the toilet device. In this example, a control unit 161 configured by a CPU is provided, and control signals of a power switch 162 and a crushing switch 164 provided in the toilet apparatus are supplied to the control unit 161. Both the power switch 162 and the pulverization switch 164 can be provided on an operation panel (none of which is shown) of the flush control unit having a hot water shower. In this case, the power switch 162 is commonly used as the power switch of the flush controller. The crushing switch 164 is a switch for driving and controlling the drive motor 138.

  Based on the control signal from the controller 161, in this example, the drive motor 138 and the water supply electromagnetic valve 166 for supplying cleaning water are controlled at a predetermined timing.

  FIG. 9 shows an example of the timing chart. FIG. 9 shows a timing chart after the power switch 162 is turned on. The crushing switch 164 is operated after the defecation is finished or after the sanitary goods are put in (FIG. 9A). When the crushing switch 164 is turned on, the drive motor 138 is driven, so that the rotational force is transmitted to the crushing means 70 via the transmission system shown in FIG. 3 and the like, and the crushing means 70 is rotationally driven (FIG. 9B). ).

  Since the crushing means 70 is constituted by a large number of rotary blades, the filth is cut between the rotary blades 74 and 76 and cut into strips by the action of the meshing rotary blades 74 and 76. Similarly, sanitary goods that have been dropped (including paper diapers as described above) are bitten between the rotary blades 74 and 76, so that the sanitary goods are in the form of a strip due to the action of the meshing rotary blades 74 and 76. It is cut by. Since the rotary blade is a cross-cut blade, sanitary articles cut into strips are further cut into fine pieces and pulverized.

  The electromagnetic valve 166 for water supply operates for a predetermined time before the pulverization processing time T1 elapses, in this example, after a predetermined time ΔT1 after the pulverization processing is started (FIG. 9C). Since the crushed water guided to the drop restricting cylinder 152 by the operation of the water supply electromagnetic valve 166 concentrates in the central part of the intermediate toilet part 100B, the crushed sanitary goods fall to the bottom toilet part 100C side in a state of containing moisture. To do. The pulverized pulverized material stays in the reservoir 109 provided in the bottom toilet unit 100C, and is then discharged to the outlet 109a side. Since the sanitary goods pulverized by this stay are somewhat softened, the pulverized sanitary goods can be discharged smoothly.

  Considering baby goods to adult goods in addition to filth, sanitary goods vary in size, and therefore, the pulverization time T1 and the water supply time T2 are selected relatively long. In this example, both the predetermined times T1 and T2 are set to about 10 to 20 seconds. These times T1 and T2 can also be configured to be adjustable from the outside. For example, it is possible to switch to three stages such as “short, medium, long” by an adjustment button provided outside. The water supply timing can also be started from the time when the pulverization process is completed as shown in FIG. 9D.

  The toilet 100 normally stores a predetermined amount of water as washing water. This washing water is normally stored so as to fill the bottom toilet part 100C and facilitates discharge of filth and the like to the drain pipe side, but it is also preferable to store in this example. In this case, in order to facilitate the pulverization of filth and sanitary goods, it is preferable that the washing water is stored so as to satisfy the pulverizing means 70 as shown in FIG. In that case, when removing the intermediate toilet part 100B, it goes without saying that at least the washing water stored in the intermediate toilet part 100B is pumped up by a pump or the like.

  A second embodiment will be described with reference to FIG. In Example 1, the case where the intermediate toilet part 100B itself was used as the attachment member 80 of the grinding | pulverization means 70 was illustrated. That is, the attachment member 80 in this case is a case where the shaft support means 90 and 92 of the crushing means 70 are attached thereto using the intermediate toilet part 100B. Therefore, the toilet 100 was divided into three.

  The toilet 100 used in Example 2 is a non-split type. That is, a normal toilet is used. However, the internal configuration of the toilet 100 is slightly different. This is because it is necessary to attach the crushing unit 60 to a portion of the toilet bowl 100 corresponding to the pool portion 109.

  The pulverizing unit 60 includes the pulverizing means 70 and its attachment member 80 as described above. The crushing means 70 is configured to be detachable from the toilet 100. Therefore, in this example, the shaft support means 90 and 92 itself of the crushing means 70 function as an attachment member 80 for the crushing means 70.

  Therefore, as shown in FIG. 10, among the integrally formed toilet 100, the left side wall 98a is attached to the left side wall 98a as a support part for supporting the rotation shafts 70a and 70b. A concave portion 99a is formed. A mounting hole 99b for mounting the pair of rotating shafts 70a and 70b is formed in the right side wall 98b facing the mounting recess 99a.

  A shaft support means 90 is provided on the left end side of the pair of rotating shafts 70a and 70b, and the shaft support means 90 is fitted and fixed to the left side wall 98a by being fitted into the mounting recess 99a. Similarly, a shaft support means 92 is also provided on the right end side of the pair of rotating shafts 70a, 70b, and this shaft support means 92 is mounted and fixed in a watertight manner in the mounting hole 99b. Thus, the crushing means 70 is attached and fixed to the left and right side walls 98a and 98b.

  Further, in order to make the crushing means 70 itself detachable from the toilet 100, the mounting hole 99b is formed as a through hole that is slightly larger than the outer shape of the crushing means 70. As a result, the crushing means 70 itself can be inserted into and removed from the toilet 100. In this example, a case is shown in which the shaft support means 90 and 92 are also inserted and removed integrally with the crushing means 70.

  As described above, the mounting hole 99b is formed in one side wall 98b of the toilet 100, and the recess 99a for fixing the pivot supporting means 90 is provided in the other side wall 98a, so that the crushing means 70 can be attached to and detached from the toilet 100. Can be attached to. When the crushing unit 60 is removed, an alternative member (packing material) for closing the mounting hole 99b is mounted and fixed so that the toilet 100 can be used.

  Since the crushing unit 60 can be removed, maintenance / inspection and replacement of the crushing means 70 can be easily performed. Since the crushing means 70 is located in the reservoir 109, it goes without saying that when removing the crushing means 70, it is necessary to drain the stored washing water.

  In both the first and second embodiments described above, the present invention is applied to a stationary toilet device. The present invention can also be applied to a portable toilet device. This is because even if this kind of simple toilet device is provided with crushing means inside, it is necessary to remove the crushing means.

  FIG. 11 is a cross-sectional view of an essential part showing an example of a portable toilet device 10 to which the present invention can be applied. This portable toilet device 10 has a toilet body 20. The toilet body 20 has a funnel-like cross-sectional shape that is substantially the same as that of a normal flush toilet (Western toilet), but the overall shape is configured as a box shape.

  In order to reduce the weight of the toilet body 20, the toilet body 20 is a molded product made of plastic in this example, but may be molded using other materials such as ceramics. A toilet seat 21 is located on the upper opening side of the toilet body 20, and a toilet lid 23 is provided to close the toilet seat 21 and the upper opening.

  The bottom portion of the toilet body 20 serves as trap water (reserved water) or filth reservoir 18. This pool portion 18 corresponds to the pool portion 109 described above. A discharge portion 22 that communicates with the reservoir portion 18 and has a substantially “H” cross section is provided, and the discharge hose 14 is connected to the discharge port 27. The discharge port 27 corresponds to the discharge port 109a described above. A connecting portion 26 is provided on the back surface portion 20 b of the toilet body 20, and an electromagnetic valve 24 that functions as an on-off valve inside the toilet body 20 is provided adjacent to the connecting portion 26.

  The electromagnetic valve 24 is controlled so as to open only when trap water (water containing dirt) in the reservoir 18 is discharged out of the toilet bowl, and is closed when the toilet is not in use. This is to prevent water leakage. In addition to preventing water leakage, the electromagnetic valve 24 also has a function of preventing compressed air from leaking when the inside of the reservoir 18 is pressurized using an air compressor (described later) that constitutes a pressure feeding means.

  Near the upper part of the toilet body 20, a flush water supply port 28 is provided on the wall 18 a on the discharge side. A connecting pipe 30 is disposed between the connecting portion 34 provided on the main body back surface portion 20 b and the water supply port 28. A branch pipe is used as the connection pipe 30, and an electromagnetic valve 32 for controlling the washing water is attached to the connection pipe 30 that faces the water supply port 28. This is because water supply from the water supply hose 12 connected to the connection portion 34 can be controlled by the electromagnetic valve 32.

  A washing hose (cleaning pipe) 240 is also connected to the branched connecting pipe 30 via an electromagnetic valve 33. The front end of the cleaning hose 240 is provided so as to protrude above the surface of the trap water in the reservoir 18. By the water injection (actually injection) by the cleaning hose 240, the inside of the reservoir 18 and the back surface of the open / close lid 212 are cleaned as will be described later.

  A rubber-like water leakage prevention pipe 29 is inserted between the water supply port 28 and the wall surface 18a, and a water leakage prevention pipe 242 is also inserted in the pool portion 18 through which the cleaning hose 240 penetrates, thereby leaking water to the outside. I'm trying to prevent it.

  A crushing means 60 for excrement and the like is provided at the bottom of the reservoir 18. As described above, the pulverizing means 60 includes the pulverizing means 70 and an attachment member for attaching the pulverizing means 70 to the toilet bowl 20. In FIG. 11, rotary blades 74 and 76 constituting the crushing means 70 are shown. Since the attachment member 80 is provided on the side wall of the toilet bowl 20, the attachment member is not shown. However, the attachment member in this case is configured so that only the crushing means 70 can be attached and detached as in the second embodiment. Therefore, a mounting hole is formed only on one side wall of the toilet 20. The filth (such as excrement) and toilet paper that have fallen into the reservoir 18 are finely pulverized by the pulverizing means 70, and the pulverized fluid is mixed with trap water and discharged.

  A control unit 50 (corresponding to the control unit 161 described above) configured by a CPU or the like is disposed inside the bottom plate 20c. The discharge solenoid valve 24, the water supply solenoid valves 32, 33, and the like described above are controlled by the control unit 50 at a predetermined timing for a predetermined time. The power switch 52 for the control unit 50 is provided on the main body back surface portion 20b, and is an upper surface portion of the main body, and an open / close switch 55 (corresponding to the above-described crushing switch) is provided on the lower surface of the toilet lid 23.

  The simple toilet device 10 further has the following structure. As shown in FIG. 11, for the pulverized material for supplying predetermined compressed air to the reservoir 18 at a predetermined position above the reservoir 18 in the toilet body 20 and below the water supply port 28. A pressure feeding means 200 is provided. A reduced diameter portion 230 is provided above the pool portion 18 and slightly above the attachment position of the pressure feeding means 200. An opening / closing lid mechanism 210 is provided on the lower surface of the reduced diameter portion 230 so as to close the reduced diameter portion 230 and seal the pool portion 18.

  The pressure feeding means 200 can be constituted by an air compressor, and the feed pipe 204 of the air compressor 200 is led out to the accumulation portion 18 side through the attaching means 206. The attachment means 206 is provided above the surface of the trap water in the reservoir 18. The air compressor 200 is fixed to a mounting plate 202 provided in the back space 20 a of the toilet body 20.

  The reduced diameter portion 230 is configured as an annular flange portion, and protrudes by a predetermined length toward the inner surface of the pool portion 18. The feed pipe 204 described above is located between the trap water in the reservoir 18 and the reduced diameter portion 230.

  As is clear from FIG. 11, the reduced diameter portion 230 is provided so that the entire portion thereof is inclined slightly toward the discharge portion 22. In this example, a rotary opening / closing lid mechanism 210 is provided on the lower surface side of the reduced diameter portion 230 so that the reduced diameter portion 230 can be closed.

  The opening / closing lid mechanism 210 has a lid body 212, and one end of the lid body 212, the right end portion in the example shown in the figure, serves as a rotation shaft portion 214. It is pivotally supported with respect to the toilet body 20 so as to be positioned. This pivotal support is pivotally supported by the toilet body 20 in a watertight manner.

  The lid body 212 is urged so that the peripheral surface thereof is in contact with the lower surface edge 234 of the reduced diameter portion 230. The lid body 212 has a shape along the lower surface edge portion 234, and normally, the rotation shaft portion 214 and the wall surface of the lower surface portion 232 are sealed so that the inside of the reservoir portion 18 can be sealed by contacting the lower surface edge portion 234. An urging spring 216 is wound between them.

  Since the reduced diameter portion 230 is provided so as to be inclined slightly to the discharge portion 22 side, the lid body 212 itself constituting the opening / closing lid mechanism 210 is also attached to be inclined to the discharge portion 22 side. If the lid main body 212 is tilted and attached in this manner, excrement that has fallen on the upper surface of the lid main body 212 does not remain and can be dropped into the pool portion 18.

  The above-described cleaning hose 240 has its tip end attached to the reservoir 18 at an angle such that cleaning water can be sprayed onto both the back side of the lid body 212 and a part of the peripheral surface of the reservoir 18. In this example, the lid main body 212 is in the vicinity of the rotation shaft portion 214 and is attached and fixed to the lower side thereof in a watertight manner. A water supply hose and a discharge hose are connected to the toilet body 20, and they are guided into a fixed toilet device (toilet).

  The above-described opening / closing switch 55 is turned on / off in association with opening / closing of the toilet lid 23 for closing the upper part of the toilet seat 21. The drive states of the discharge solenoid valve 24, the water supply solenoid valve 32, the cleaning solenoid valve 33, and the air compressor 200 described above are controlled by a control signal from the control unit 50. In this example, pulverization is performed in association with opening and closing of the toilet lid 23. Other than that, the air compressor 200 is driven after the pulverization process is completed, and compressed air is supplied into the reservoir 18 to be pressurized. The pressurization processing time is set to a time for the internal pressure in the reservoir 18 to rise to a predetermined value (for example, 2 atm). The predetermined value of the internal pressure refers to a pressure at which fluid can be reliably pumped and discharged into the fixed toilet device via the discharge hose.

  When the pressurization time elapses, the discharge solenoid valve 24 is driven in a state where the air compressor 200 is driven, that is, in a state where compressed air is fed into the reservoir 18. When the discharge solenoid valve 24 is driven and the discharge port 27 is opened, the trap water (flowing material) in the reservoir 18 is pumped by compressed air and discharged to the discharge hose side. When the pumping period elapses, energization of the discharge solenoid valve 24 is released and the driving of the air compressor 200 is stopped. Thus, the discharge port 27 is closed. Thereafter, the water supply electromagnetic valve 32 is activated to start water supply into the reservoir 18. The water supply time is set to a water injection time in which the trap water in the reservoir 18 becomes a predetermined amount. The electromagnetic valve 33 for cleaning is also operated in synchronization with the operation of the electromagnetic valve 32 for water supply, and water is injected into the reservoir 18 through the cleaning hose 240, specifically, injection and accumulation on the back surface of the lid body 212. Injection to the wall surface of the part 18 is performed. By the spray of the cleaning water, the back surface of the lid main body 212, the wall surface of the reservoir 18 and the crushing means 70 are cleaned.

  In the second and third embodiments described above, a frame member having a rectangular shape may be added, and the crushing means 70 including the attachment member 80 may be handed over to the frame member. In this case, since the crushing means 70 is supported by the frame member, the mounting state (posture) of the crushing means 70 is stable, and the whole frame member can be detached from the mounting holes 79a and 79b, so that the demounting work is easy. Yes.
