＜Water supply unit＞ In the base part 250, a water supply unit 400 is arranged at the rightmost position. The water supply unit 400 is connected to the water channel through a hose (not shown) outside the main body 200.

The water supply unit shown in FIGS. 28 to 31 has a water pump 600 and an open water passage 405A, and is described below as the water supply unit 400A.

The water supply unit 400A includes a strainer 401A, a constant flow valve 402A, a water stop solenoid valve 403A, a vacuum circuit breaker 404A, and an open water path 405A.

The purified water flowing through the water pipe (not shown) is supplied to the strainer 401A as washing water. The dirt or impurities contained in the washing water can be removed by the strainer 401A.

The washing water from which dirt and impurities have been removed by the strainer 401A is supplied to the water stop solenoid valve 403A. The water stop solenoid valve 403A switches the supply state of washing water to the downstream side. The operation of the water stop solenoid valve 403A is controlled by a control unit (not shown). When washing water is supplied from the water stop solenoid valve 403A to the constant flow valve 402A, the washing water is supplied to the vacuum circuit breaker 404A. The constant flow valve 402A controls the flow rate of the washing water flowing in the water supply unit 400A to be fixed.

The vacuum circuit breaker 404A includes a vacuum adapter 406A, a vacuum cover 407A covering the vacuum adapter 406A, and a vacuum circuit breaker valve 408A supported between the vacuum adapter 406A and the vacuum cover 407A.

The vacuum adaptor 406A has an inflow port 409A into which the washing water from the constant flow valve 402A flows, an outflow port 410A to the main water path, and an outflow port 411A to the open water path 405A. The vacuum cover 407A is provided with a suction port 412A.

The water supply unit 400 flows the washing water supplied from the inflow port 409A to the outflow port 410A leading to the main water channel and the outflow outlet 411A leading to the open water channel 405A. The washing water supplied to the outflow port 410A leading to the main water channel flows to the downstream side by the output of the water pump 600 arranged on the downstream side. The washing water that has not been supplied to the outflow port 410A is led to the open water passage 405A from the outflow port 411A, and is drained into the toilet.

A flow sensor 570, a heat exchanger 500, etc. are arranged on the upstream side of the water pump 600 of the main waterway. The flow sensor 570, the heat exchanger 500, etc., have a large flow path resistance. Therefore, in a configuration in which the washing water flows to the downstream side only by the output of the water pump 600, the load on the water pump 600 is large.

In this embodiment, a fixed orifice 413C can be provided on the side of the open water path to apply a water pressure equivalent to the flow path resistance of the flow sensor 570 or the heat exchanger 500 to the outlet 410A leading to the main water path. , And the load on the water pump 600 can be suppressed.

In addition, because the washing flow rate set by the user is smaller, the flow rate through the fixed orifice 413C will become more, and the water pressure applied to the outlet 410 leading to the main waterway will become larger, which is applied to the inlet of the water pump 600 The water pressure will also become larger, so the pulsation of the washing water flowing from the nozzle device 700 can be eliminated, and milder washing water can be provided. Conversely, because the more the washing flow rate set by the user, the smaller the flow rate through the fixed orifice 413C, and the smaller the water pressure applied to the outlet 410 leading to the main waterway, which is applied to the inlet of the water pump 600 The water pressure becomes smaller, so it is possible to provide stronger washing water without eliminating the pulsation of the washing water flowing from the nozzle device 700.

In the vacuum circuit breaker 404, the vacuum circuit breaker valve 408 is usually pushed up by the washing water under water pressure, so the flow path to the suction port 412 is closed, but when the upstream side becomes negative pressure, The vacuum circuit breaker valve 408 will be lowered, and external air will be introduced from the suction port 412 to relieve the negative pressure on the upstream side, which can prevent the danger of sewage flowing backward from the nozzle device 700 or the open waterway.

The following approach can be considered: in the above-mentioned embodiment of the water supply unit, the water pump 600 is eliminated.

The water supply unit shown in FIGS. 32 to 34 eliminates the structure of the water pump 600, and is described below as the water supply unit 400B.

The water supply unit 400B includes a strainer 401B, a water stop solenoid valve 403B, a pressure reducing valve 402B, a vacuum circuit breaker 404B, and an open water passage 405B.

The purified water flowing through the water pipe (not shown) is supplied to the strainer 401B as washing water. The dirt or impurities contained in the washing water can be removed by the strainer 401B.

The washing water from which dirt and impurities have been removed by the strainer 401B is supplied to the water stop solenoid valve 403B. The water stop solenoid valve 403B switches the supply state of the washing water to the downstream side. The operation of the water stop solenoid valve 403B is controlled by a control unit (not shown). When the washing water is supplied from the water stop solenoid valve 403B to the pressure reducing valve 402B, the pressure of the washing water flowing in the water supply unit 400B is reduced to a fixed pressure by the pressure reducing valve 402B.

The vacuum circuit breaker 404B includes a vacuum adaptor 406B, a vacuum cover 407B covering the vacuum adaptor 406B, and a vacuum circuit breaker valve 408B supported between the vacuum adaptor 406B and the vacuum cover 407B.

The vacuum adaptor 406B has an inflow port 409B into which the washing water from the pressure reducing valve 402B flows, an outflow port 410B to the main water path, and an outflow port 411B to the open water path. The vacuum cover 407B is provided with a suction port 412B.

The vacuum circuit breaker 404B is arranged on the downstream side of the pressure reducing valve 402B, and the washing water decompressed to a fixed pressure by the pressure reducing valve 402B is supplied into the vacuum circuit breaker 404B from the inflow port 409B, and flows to the outflow port 410B.

In the vacuum circuit breaker 404B, the vacuum circuit breaker valve 408B is usually pushed up by the washing water by water pressure, so the flow path leading to the suction port 412B is closed. When the upstream side becomes negative pressure, the vacuum circuit breaker valve 408B will drop, and external air will be introduced from the suction port 412B to release the negative pressure on the upstream side, thereby preventing the danger of sewage flowing backward from the nozzle device 700 or the open waterway.

The following approach can be considered: In the embodiment of the water supply unit described above, a pump and a pressure reducing valve are added.

The water supply unit shown in FIGS. 35 to 37 is a configuration in which a water pump 600 and a pressure reducing valve 402C are added, and is described below as a water supply unit 400C.

The water supply unit 400C includes a strainer 401C, a water stop solenoid valve 403C, a pressure reducing valve 402C, a vacuum circuit breaker 404C, and an open water passage 405C.

The purified water flowing in the water pipe (not shown) is supplied to the strainer 401C as washing water. The dirt or impurities contained in the washing water can be removed by the strainer 401C.

The washing water from which dirt and impurities have been removed by the strainer 401C is supplied to the water stop solenoid valve 403C. The water stop solenoid valve 403C switches the supply state of the washing water to the downstream side. The operation of the water stop solenoid valve 403C is controlled by a control unit (not shown). When the washing water is supplied from the water stop solenoid valve 403C to the pressure reducing valve 402C, the pressure of the washing water flowing in the water supply unit 400C is reduced to a fixed pressure by the pressure reducing valve 402C.

The vacuum circuit breaker 404C includes a vacuum adaptor 406C, a vacuum cover 407C covering the vacuum adaptor 406C, and a vacuum circuit breaker valve 408C supported between the vacuum adaptor 406C and the vacuum cover 407C.

The vacuum adaptor 406C has an inflow port 409C into which the washing water from the pressure reducing valve 402C flows, an outflow port 410C to the main water path, and an outflow port 411C to the open water path. The vacuum cover 407C is provided with a suction port 412C.

The vacuum circuit breaker 404C is arranged on the downstream side of the pressure reducing valve 402C. The washing water can be decompressed to a fixed pressure by the pressure reducing valve 402C, supplied into the vacuum circuit breaker 404C from the inflow port 409C, and further decompressed by passing through the fixed orifice 413C, and flow to the outflow port 410C.

Because the smaller the washing flow rate set by the user, the smaller the flow rate through the fixed orifice 413C, and the greater the water pressure applied to the outlet 410C, and the greater the water pressure applied to the inlet of the water pump 600. The larger the value is, the pulsation of the washing water flowing from the nozzle device 700 can be eliminated, and a milder washing water can be provided. Conversely, because the more the washing flow rate set by the user, the more the flow rate through the fixed orifice 413C will become, and the water pressure applied to the outlet 410C will become smaller, and the water pressure applied to the inlet of the water pump 600 will also become smaller. Since it becomes smaller, it is possible to provide stronger washing water without eliminating the pulsation of the washing water flowing from the nozzle device 700.

In the vacuum circuit breaker 404C, the vacuum circuit breaker valve 408C is usually pushed up by the washing water under water pressure, so the flow path leading to the suction port 412C is closed. When the upstream side becomes negative pressure, the vacuum circuit breaker valve 408C will be lowered, and external air will be introduced from the suction port 412C to release the negative pressure on the upstream side, thereby preventing the danger of sewage flowing backward from the nozzle device 700 or the open waterway.

In case, in the case of sewage flowing backward from the nozzle device 700, since the sewage flowing in from the outflow port 410C can still be reduced by fixing the orifice 413C, the backward flow of sewage can be suppressed.

＜Heat exchanger＞ A heat exchanger 500 is arranged on the left side of the water supply unit 400 of the base part 250. The outflow port 410 of the water supply unit 400 and the heat exchanger 500 are connected by a flexible hose (not shown).

The heat exchanger 500 is described in detail below according to FIGS. 38 to 50.

The heat exchanger 500 is formed in a low-height rectangular parallelepiped shape, and a surface with a large area is placed and fixed on the base part 250.

The heat exchanger 500 includes a lower cover 510, an upper cover 520, and a front structure 530 formed of heat-resistant resin. The lower cover 510 and the upper cover 520 are integrally formed by welding or the like, and the front part 530 may be integrally formed by welding or the like at the front part thereof.

In the front structure 530, an inlet tube 532 is formed vertically protruding upward from the right side of the upper surface. The inlet tube 532 is provided with an inlet 531 for washing water leading to the internal space of the heat exchanger 500. In the front structure 530, an outlet tube 534 is formed vertically protruding upward from the left side of the upper surface. The outlet tube 534 is provided with an outlet 533 for washing water from the internal space of the heat exchanger 500.

The inlet tube 532 can be arranged on the right side of the heat exchanger 500 to shorten the interval with the water supply unit 400, and shorten the piping connecting the water supply unit 400 and the inlet tube 532, thereby improving the piping workability.

The upper surface of the upper casing 520 is divided by ribs to form a temperature detecting component mounting portion 521. The temperature detecting component mounting portion 521 is a mounting portion of the temperature detecting component for detecting the empty firing of the heat exchanger 500. In this embodiment, the temperature detection unit uses a temperature fuse 522, and the temperature detection unit mounting part 521 is provided with a temperature fuse 522 and wiring 523 to the temperature fuse 522. Since the heater structure 580 of the heat exchanger 500 is set to have a higher temperature on the inlet 531 side than on the outlet 533 side, the thermal fuse 522 is installed at a position corresponding to the flow path on the inlet 531 side. The part where the temperature fuse 522 is installed in the temperature detection unit mounting part 521 is configured to have a thinner wall thickness to more reliably detect the dry burn of the heat exchanger 500. The temperature detection component mounting portion 521 is covered by the temperature detection component cover 540 fixed to the upper casing 520. The thermal fuse 522 is a circuit configuration that blocks only the power supply to the heat exchanger 500.

In the heat exchanger 500, a flow sensor 550 is attached to the inlet tube 532, and a hot water discharge block 560 is attached to the outlet tube 534 through a common ground connection terminal plate 565.

The terminal plate 565 is formed of a single metal plate and is connected to a ground terminal (not shown), and the ground terminal is connected to the power ground. The terminal board 565 is always in contact with the washing water at the inlet 531 and the outlet 533. Thereby, even when the basic insulation of the heater structure 580 is broken, it is possible to prevent leakage of electricity through the washing water to the user or the water pipe.

As shown in FIGS. 42 to 44, the flow sensor 570 includes a flow sensor cover 571, a flow sensor cover 572, an inlet water temperature sensor 573, an inlet temperature sensor fixture 574, and a flow sensor The detector shaft 575, the impeller 576, and a detection assembly 577 that detects the number of rotations of the impeller 576.

The flow sensor cover 571 has an inlet 578 from the water supply unit 400 and an outlet 579 to the heat exchanger 500.

A flow sensor shaft 575 is installed between the flow sensor housing 571 and the flow sensor housing cover 572, and the aforementioned flow sensor shaft 575 is equipped with an impeller 576. The inflow port 578 is arranged to supply washing water from the lower front part in the tangential direction of the impeller 576, and the impeller 576 is rotated with the supplied washing water centered on the flow sensor shaft 575. The detection component 577 is disposed on the upper part of the flow sensor 570, and detects the number of rotations of the impeller 576, and outputs the measured flow value to the control unit. Thereby, it is possible to prevent the detection assembly 577 from being unable to detect the number of rotations of the impeller 576 due to dirt or dirt easily accumulating below.

The inlet water temperature sensor 573 can be fixed by the inlet water temperature sensor fixture 574 in the flow sensor cover 571. The water inlet temperature sensor 573 is installed in such a way that the water inlet temperature sensor fixture 574 covers the metal part so that the metal part is not exposed to the outside of the flow sensor 570. In this way, in case the insulation of the wires that have been wired around is destroyed, it is still possible to prevent leakage of electricity to the washing water through the metal part of the water temperature sensor 573.

The washing water flowing around the impeller 576 flows out from the upper part of the front to the left, and flows through the water inlet temperature sensor 573 to the outlet 579.

Furthermore, in this embodiment, although the flow sensor 570 is installed at the inlet 531, it can also be configured to be installed downstream of the outlet 533. In this configuration, since the washing water heated by the heat exchanger 500 is supplied to the flow sensor 570, the risk of scale adhesion to the inside of the flow sensor 570 increases. Therefore, the method of this embodiment has advantages in quality.

The structure of the internal space of the heat exchanger 500 will be explained based on FIGS. 45 to 50. Furthermore, the heater assembly 580 on the lower side of FIG. 46 shows a state in which it is turned 180 degrees.

In the internal space of the heat exchanger 500, the heater structure 580 is arranged in the horizontal direction, and is sandwiched and fixed by the upper cover 520 and the lower cover 510 with the lower sealing body 581 and the upper sealing body 582 interposed therebetween.

The heater structure 580 has a terminal portion 583 at the center of the end portion on the front structure 530 side. The terminal portion 583 passes through the front structure body 530 to connect a lead wire (not shown) to the heater of the heater structure body 580. The lead wires connected to the terminal portion 583 are drawn out through the lead-out passage (not shown) formed in the front structure body 530. In the heater structure 580, a plurality of through holes 584 constituting a part of the flow path are formed on the end portion side opposite to the end portion where the terminal portion 583 is provided.

The internal space of the heat exchanger 500 is divided into the vertical direction by the heater structure 580, and the divided upper space and the lower space are almost equal in volume. In the upper space and the lower space, an upper sealing body 582 and a lower sealing body 581 composed of silicone rubber are respectively arranged.

The upper sealing body 582 has a surrounding sealing body 582a, and three compartmental sealing bodies 582b, 582c, and 582d extending in the front-rear direction and connected to the surrounding sealing body 582a. The surrounding sealing body 582a and the partition sealing bodies 582b, 582c, and 582d are in close contact with the inner surface of the upper casing 520 and the upper surface of the heater assembly 580 to seal, and a flow is formed between the inner surface of the upper casing 520 and the heater assembly 580. Road (upper flow path).

The upper sealing body 582 is provided with a connecting sealing body 582e. The connecting sealing body 582e connects the left and right compartment sealing body 582b and the compartment sealing body 582d to the front part 530 side, and is connected to the central compartment sealing body 582c. The connecting sealing body 582e forms a surface on the heater structure 580 side lower than the other parts of the upper sealing body 582, and forms a flow path (upper flow path) between the connecting sealing body 582e and the heater structure 580.

The lower sealing body 581 has a peripheral sealing body 581a, and three partition sealing bodies 581b, 581c, and 581d extending in the front-rear direction and connected to the peripheral sealing body 581a. The peripheral sealing body 581a and the partition sealing bodies 581b, 581c, and 581d are in close contact with the inner surface of the lower housing 510 and the upper surface of the heater assembly 580 to seal, and a flow path is formed between the inner surface of the lower housing 510 and the heater assembly 580 (Lower flow path).

The lower sealing body 581 is provided on the front structural body 530 side: a right connecting sealing body 581e, connecting the right peripheral sealing body 581a and the central compartment sealing body 581c; and a left connecting sealing body 581f, connecting the left peripheral sealing body 581a and the center The zoning seal 581c. The right connecting sealing body 581e and the left connecting sealing body 581f are formed on the heater structure 580 side lower than the other parts of the lower sealing body 581. Thereby, a flow path (lower flow path) is formed between the right connecting sealing body 581e and the heater assembly 580, and between the left connecting sealing body 581f and the heater assembly 580.

The heater assembly 580 includes a heater (not shown), and the heater is arranged slightly separated from the surrounding sealing body 582a of the upper sealing body 582 and the partition sealing bodies 581b, 581c, and 581d. In addition, the heater is arranged slightly separated from the surrounding sealing body 581a of the lower sealing body 581 and the partition sealing bodies 581b, 581c, and 581d. This prevents the heater from overheating locally and suppresses the deterioration of durability.

The heater sets the ratio of the power on the inlet 531 side to the power on the outlet 533 side so that the power on the inlet 531 side becomes higher. In this embodiment, the ratio of the power on the side of the inlet 531 to the power on the side of the outlet 533 is set to 3 to 2.

The washing water supplied from the inlet 531 flows into the flow path between the compartmental sealing body 582b on the right side of the upper space and the surrounding sealing body 581a. The washing water flows toward the rear side while being heated by the heater structure 580, and flows from the through hole 584 into the flow path between the partitioned sealing body 581b and the surrounding sealing body 581a on the right side of the lower space. It flows toward the front side while being heated by the heater structure 580, passes over the right connecting sealing body 581e, and flows into the flow path between the right divided sealing body 581b and the central divided sealing body 581c.

The washing water flows toward the rear side while being heated by the heater structure 580, and flows from the through hole 584 into the flow path between the compartmental sealing body 582b on the right side of the upper space and the central compartmental sealing body 582c. The washing water flows toward the front side while being heated by the heater structure 580, passes over the connecting sealing body 582e, and flows into the flow path between the central compartmental sealing body 582c and the left compartmental sealing body 582d. The washing water flows toward the rear side while being heated by the heater structure 580, and flows from the through hole 584 into the flow path between the partitioned sealing body 581c in the center of the lower space and the connecting sealing body 581d on the left side.

The washing water flows toward the front side while being heated by the heater structure 580, passes over the left connecting sealing body 581f, and flows into the flow path between the surrounding sealing body 581a and the left connecting sealing body 581d. The washing water flows backward while being heated by the heater structure 580, and flows from the through hole 584 into the flow path between the peripheral sealing body 582a of the upper space and the partition sealing body 582d on the left side. The washing water flows forward while being heated by the heater structure 580, and is supplied to the nozzle device 700 from the outlet 533 through a hose (not shown).

The following can be considered: the inlet 531 is formed on the upper casing 520 side, the outlet 533 is formed on the lower casing 510 side, and the washing water flows through the upper flow path and then flows to the lower flow path. . With this configuration, it can be presumed that the amount of movement of the flow in the up and down direction can be reduced, and the flow path resistance can be set to be small.

However, in this configuration, a piping space for the outlet 533 is required below the lower cover 510, and there is a problem that the arrangement space becomes larger. In addition, the piping operation of the outlet 533 is performed in the gap between the lower cover 510 and the base portion 250, and there is a problem of poor workability.

In the present embodiment, the washing water alternately flows through the upper flow path and the lower flow path, and a plurality of flow paths are respectively formed in the upper and lower sides.

In this embodiment, four flow paths are formed in the upper and lower sides, respectively. In this way, the inlet 531 and the outlet 533 can be formed on the side of the upper housing 520. Thereby, the space for the piping of the inlet 531 and the outlet 533 can be formed only on the side of the upper casing 520, and the problem that the installation space becomes larger can be solved.

In addition, although four flow paths are formed on the upper and lower sides, two flow paths may be used, or six or more flow paths may be formed. By configuring the upper and lower flow paths in plural, the inlet 531 and the outlet 533 can be formed on the upper cover 520 side.

The inner surface of the upper casing 520 constituting the flow path may be formed with a convex portion 524 to form a concave-convex shape. The convex part 524 is continuously formed in the shape of a mountain, and is formed with a steep slope on the upstream side and a gentle slope on the downstream side.

The inner surface of the lower cover 510 constituting the flow path may be formed with a convex portion 514 to form a concave-convex shape. The convex part 514 is continuously formed in a mountain shape, and is formed with a steep slope on the upstream side and a gentle slope on the downstream side.

As shown in Fig. 49, the convex portions 514 and 524 have a shape that approaches the heater structure 580 on the upstream side. Therefore, the washing water flowing in the flow path is detected upstream by the convex portions 514 and 524 toward the heater. The constituent body 580 is guided on the side, and flows over the top of the convex portions 514 and 524 and flows on the gentle slope on the downstream side. Since the volume of the flow path becomes wider after passing over the tops of the convex parts 514 and 524, the washing water becomes a turbulent flow, and the temperature is uniformized. By narrowing and widening the flow path with the convex portions 514 and 524, the thermal conductivity can be improved and the temperature of the washing water can be made uniform.

By increasing the thermal conductivity of the heater assembly 580, the surface temperature of the heater assembly 580 can be suppressed, and the adhesion of scale to the heater assembly 580 can be suppressed.

The heater structure 580 is equipped with a heater (not shown). The heater is slightly separated from the upper sealing body 582 and the lower sealing body 581. This prevents the heater from overheating and suppresses the effect of scale on the heater structure 580. Attached.

When the bubbles have penetrated into the heat exchanger 500, the bubbles will stay on the downstream side of the convex portions 514 and 524 as shown in FIG. 49.

In this embodiment, since the convex portions 514 and 524 are formed as gentle slopes on the downstream side as shown in FIG. 500 discharged.

A nozzle device 700 is arranged on the left of the heat exchanger 500. The detailed configuration of the nozzle device 700 will be omitted.

＜Water pump＞ On the right side of the nozzle device 700, a water pump 600, which is a variable discharge amount component, is provided. In this embodiment, the water pump 600 uses a diaphragm pump.

Furthermore, it is also possible to set it as the structure which does not use the water pump 600.

As shown in FIGS. 51 to 55, the water pump 600 includes a pump mechanism portion 610 and a motor portion 620, and is formed in a substantially cylindrical shape. The pump mechanism portion 610 is provided with an elastic member A630 covering the entire circumference of the end portion side. The motor portion 620 is provided with the elastic member B640 so as to cover the entire circumference of the end side opposite to the elastic member A630. The elastic member A630 and the elastic member B640 are formed of an elastic material such as foamed resin.

The water pump 600 is installed in the recess 605a of the pump housing 605 in a state where the elastic member A630 and the elastic member B640 are installed. The motor part 620 of the water pump 600 is fixed by engaging the claw part 606 a with the fixing claw 605 b of the pump cover 605 by the pump fixing tool 606.

The water pump 600 is formed in a cylindrical shape, and a water supply cylinder 600b having a water supply port 600a and a discharge cylinder 600d having a discharge port 600c are formed to protrude perpendicularly from the end surface of one side with respect to the end surface. The water pump 600 is installed in a horizontal direction with the end surface of the water supply cylinder 600b and the discharge cylinder 600d facing forward.

The pump cover 605 is fixed to a predetermined position of the base part 250 via the elastic member C650.

The water pump 600 can absorb the vibration of a wide range of frequencies through the elastic member A630, the elastic member B640, and the elastic member C650, thereby effectively suppressing the transmission of the vibration to the main body 200.

The lead 607 of the water pump 600 can be restricted from moving by the fixing claw 606b and the locking claw 605c.

Since the water pump 600 is fixed to the base portion 250 by screw locking, claw fitting, or the like, the water pump 600 can be removed regardless of the nozzle device 700, and the maintenance workability can be improved. In addition, it is possible to prevent the vibration of the water pump 600 from being directly transmitted to the nozzle device 700.

In addition, as shown in FIG. 55, a drain port 608 is formed in the pump cover 605. When the pump mechanism part 610 of the water pump 600 is damaged and water leakage occurs, water can be drained from the drain port 608. The water drained from the drain port 608 can be drained into the toilet 110 from the base portion 250 through the inclined surface 240.

In this embodiment, a detection component (not shown) for detecting water discharged from the drain port 608 is provided. The detection component detects the occurrence of water leakage in the pump mechanism 610 and reports the failure.

In this embodiment, although the detection component is configured to detect water from the drain 608, it is not limited to this component, as long as it can detect the water leakage from the pump mechanism 610. In addition, the detection component can also be configured to detect the energization of a pair of terminals due to water leakage, and other well-known configurations can be used.

The water supply port 600a of the water pump 600 is connected to the outlet 533 of the heat exchanger 500 by a connection hose made of soft resin.

The front end wall portion 35 of the valve seat portion 34 allows the valve portion 4a of the suction valve body 4 to contact and separate, and is configured to open and close the suction hole 32 freely. Compared to the case where three valve seat portions 34 are formed, two suction valve main bodies 4 are provided, and one of the valve seat portions 34 is not covered by the suction valve main body 4.

When the output shaft 11a of the motor 11 is rotated, the eccentric rotating body 9 attached to the output shaft 11a will rotate, and the rocking plate 7 will be shaken through the crankshaft 8, and the driving part 51 of the diaphragm 50 will reciprocate. With the reciprocating movement of the driving part 51, the diaphragm 50 will repeatedly expand and compress. Thereby, the pump chamber 25 formed by the valve seat portion 34 of the middle cover 3 and the diaphragm 50 will compress and expand.

When the pump chamber 25 expands, the pump chamber 25 becomes negative pressure, and the valve portion 4a of the suction valve body 4 is separated from the suction valve seat portion 35a in a manner of being pulled apart. The suction hole 32 of the suction passage 30 formed in the front end wall portion 35 of the valve seat portion 34 is opened to the pump chamber 25. Thereby, the liquid flows from the suction hole 12 into the suction passage 30 formed by the lid suction chamber 38 of the lid body 1 and the suction chamber 33 of the middle lid body 3 and flows into the pump chamber 25.

In addition, when the pump chamber 25 becomes a negative pressure, the discharge valve membrane 52 of the diaphragm 50 is in close contact with the valve seat portion 34. Thereby, it is possible to prevent the outflow of the liquid to the common discharge space 36 or the back flow from the common discharge space 36. The common discharge space 36 is the outer surface of the discharge valve membrane 52, the diaphragm 54 and the recessed portion of the middle cover 3 The space formed by 39.

When the pump chamber 25 is compressed, the valve portion 4a of the suction valve body 4 is in pressure contact with the suction valve seat portion 35a. The suction hole 32 of the suction passage 30 formed in the front end wall portion 35 of the valve seat portion 34 is blocked by the valve portion 4a. Thereby, the suction valve body 4 prevents the liquid from the suction hole 32 from flowing in and out. In addition, due to the compression of the pump chamber 25, the discharge valve membrane 52 has an expanded diameter and is separated from the valve seat portion 34, and the liquid in the pump chamber 25 is sent to the common discharge space 36 under pressure.

In addition, when the pump chamber 25 is compressed, the discharge valve membrane 52 expands in the direction of the common discharge space 36 and presses the liquid existing in the common discharge space 36 to push the liquid to the discharge hole 37. Thereby, the membrane surface on the outer side of the discharge valve membrane 52 will have the function of pressure-feeding liquid.

When the pump chamber 25 where the valve portion 4a is not provided is compressed, the suction hole 32 is opened as it is, so when the pump chamber 25 is compressed, the liquid in the pump chamber 25 will be pushed back from the pump chamber 25 The amount of liquid in the direction of the suction path 30 is large. The liquid pushed back into the suction path 30 is pressure sent to the pump chamber 25 provided with the valve portion 4a.

On the other hand, although the discharge valve membrane 52 has an expanded diameter in the direction of the common discharge space 36, the pressure applied to the discharge valve membrane 52 is reduced, and the discharge amount to the common discharge space 36 becomes small, and the sanitary washing device The pressure of the cleansing water sprayed on the part of the human body will become lower. In other words, the ejection to the part of the human body will be temporarily interrupted or will be in a low-pressure ejection state.

Because the position where the valve part 4a is arranged produces washing water power that allows the normal amount of water to be sprayed to the local parts of the human body, the water pressure at the position where the valve part 4a is arranged and the water pressure at the position where the valve part 4a is not arranged will fluctuate. , And produce the pulsation of washing water pressure.

At the position where the valve part 4a is arranged, the liquid that has been pushed back to the suction path 30 is pressure sent to the pump chamber 25 where the valve part 4a is arranged, and acts between the pump chambers 25 to generate the rotation direction of the actuator Sequence of the washing water pressure when the diaphragm is compressed.

When comparing the performance of a diaphragm pump with two valve parts 4a and a diaphragm pump with three valve parts 4a according to the present disclosure, the two valves are provided in the present disclosure. The diaphragm pump of the configuration of the part 4a can generate a washing water pressure that is about twice the maximum washing water pressure of the diaphragm pump of the configuration of the three valve parts 4a.

A drying device 220 is arranged at the left position of the nozzle device 700. The drying device 220 uses the generated warm air to dry the water adhering to the cleaned part.

A deodorizing device 230 that deodorizes the odor in the toilet 110 is arranged at the left position of the drying device 220. Industrial availability

Since the sanitary washing device of the present disclosure can improve the installation workability of various functional parts to the base part, it can also be applied to sanitary washing devices that do not have a toilet cover.
