Description

Remote operation type drainage plug device

Technical Field

The present invention relates to a remote-controlled drain cock device for opening and closing a drain port of a bowl body by operating an operation unit provided at a distance from the drain port, and more particularly, to an operation unit structure of the remote-controlled drain cock device.

Background

Conventionally, a method of disposing sewage generated in a tub such as a bathtub or a washbasin by providing a drain port in a bottom portion of the tub or the like and discharging the sewage from the drain port to a lower drain side through a pipe assembly is widely known. Further, there is a method of providing a valve body so that water can be stored in the bowl when the valve body covers the drain port and opening the drain port when the valve body is lifted up and separated from the drain port. It is known to lift a valve body to open and close a drain opening by operating an operating unit located remotely from the valve body or the drain opening, such as an operating unit located above the rim of the bowl or the side of the bowl.

As described in patent document 1 (japanese utility model application No. 6-35370), a remotely operated drain plug device is known which is composed of a drain port provided at the bottom of a bowl, a valve body provided above the drain port, and an operation unit located at a position spaced from the valve body, and the drain port is opened and closed by remote operation of the operation unit.

Specifically, the remote-operated drain cock device described in patent document 1 includes a tubular drain port body having a drain port at an upper edge thereof, a shaft-shaped locking shaft provided in the drain port body and installed just below the drain port, a mechanism portion constituted by a tubular mechanism body in which the locking shaft is installed, a disc-shaped valve body having a lower surface center connected to the locking shaft and used for opening and closing the drain port, a connection assembly connected below the drain port body and provided with an insertion portion for inserting a release wire described below, a shaft-shaped operating member provided with a button for performing a pressing operation, and a release wire serving as an operation transmission member for transmitting an operation of the operating member, the release wire being constituted by a tubular outer tube and an inner wire passing in and out of the outer tube.

The inner wire and the release wire are flexible in the lateral direction and rigid in the axial direction.

The mechanism part is provided with a thrust locking mechanism, after the installation is finished, the metal wire is released to drive the locking shaft, and the locking shaft can be repeatedly switched between ascending, locking/unlocking and descending each time the operating piece is pressed.

Further, in the related art, for the purpose of improving workability and the like, an operation unit body as an operation member guide part is not provided, but an operation through hole (guide post) for guiding, in which an operation member can freely enter and exit, is provided at a back surface of a water supply metal fitting that supplies water to the tub. That is, the water supply metal fitting serves as the operation unit body. The upper part of the bathtub for installing the remote-operated drain cock device is provided with an opening, the bottom surface of the bathtub is provided with an installation hole for installing a drain outlet body, and the flange part of the bathtub near the upper edge of the opening or the table surface of the bathtub is provided with a metal fitting installation hole for installing a water supply metal fitting.

The remote-operated drain cock device composed of the above-described components is mounted to a bathtub serving as a tub body by the following construction.

First, the drain outlet body is mounted to the mounting hole of the tub, and the water supply metal fittings are mounted to the metal fitting mounting holes, respectively.

Next, one end of the release wire is inserted into the branch pipe of the connection assembly, and then the release wire is pulled upward from the upstream end portion and connected to the mechanism portion.

By this connection, the mechanism portion can be repeatedly switched between the raising and locking/releasing and lowering of the locking shaft with the locking shaft of the mechanism portion being carried along with the entry and exit of the inner wire into and out of the outer tube each time.

Next, the upstream end portion of the connecting member is connected to the lower end of the drain opening body.

Next, the operation member is inserted into the operation through hole of the water supply metal fitting.

Next, the other end of the release wire is connected with the operation member and the water supply metal fitting as the operation unit body. When the operation piece is connected, the end parts of the inner metal wires are fixedly connected to the lower end of the operation piece, and the end part of the outer tube is fixedly connected to the water supply metal fitting.

Next, the valve body is coupled to the locking shaft of the mechanism part, thereby completing the installation of the existing remote operated drain cock apparatus.

When the remote-operation type drain cock device with the structure is used, the valve body is firstly descended, and the valve body is in a state of blocking the drain opening. At this point, the locking shaft is released and is in the lowered position.

When the operating element is pressed in this state, the inner wire moves toward the drain port side in the outer pipe due to the pressing of the operating element, and the lock shaft of the mechanism portion is pushed up by the inner wire and the mechanism portion raises the lock shaft.

The valve body mounted on the front end of the locking shaft is also lifted up and away from the drain port, which is in an open state. When warm water is stored in the bathtub, the warm water is used as waste water and is discharged to a sewer through the inside of the water outlet body and the inside of the connecting component.

The push button of the operation unit is pressed again, the pressing action is transmitted to the locking shaft again through the inner metal wire, the ascending state of the locking shaft is released, and the locking shaft descends under the action of gravity. The valve body descends along with the water outlet, and the valve body moves to a position connected with the water outlet and blocks the water outlet.

Then, by pressing a button of the operation unit, the drain port can be opened and closed by remote operation at a position away from the valve body.

Further, in the related art, by providing an operation through hole for installing an operation member in a water supply metal fitting, it is not necessary to separately prepare an operation unit body as an operation member support, or to provide a through hole for an operation unit body to install the operation unit body to the vicinity of the tub, thereby eliminating the work of drilling or installation.

In the remote-operated drain plug device described in patent document 1, the operating element is formed of a rod-like member having a button portion at an end thereof, and the upper end thereof is provided on the water supply fitting so as to be operated, and the lower end thereof is connected to a release wire as an operation transmission member.

Therefore, the operating member is vertically inserted into the metal fitting mounting holes of the tub flange and the table top, which are provided with the water supply metal fittings.

When the mounting position of the operating member on the water supply fitting is designed, the front surface of the water supply fitting is provided with a water supply port, and the operating member arranged in the vertical direction interferes with the water supply port. Therefore, the operation member cannot be disposed on the front surface of the water supply metal fitting.

And the water supply metal fittings are provided with water supply operation handles for opening and closing the water supply ports and adjusting the water amount in the left and right directions, and the operation pieces arranged in the up and down directions obstruct the water supply operation handles. Therefore, the operation member cannot be provided on the side of the water supply metal fitting. Although some water supply fittings are provided with a water supply operation handle only on one side, the design of the water supply operation handle and the button part is greatly different in the prior art, the water supply operation handle is operated in a rotating manner in the operation direction, and the operation piece is operated in a vertical pushing and pulling manner or a pressing manner, so that the appearance design and the operability are deteriorated due to completely different shapes and operation methods.

As a result, when the operation member is provided in the water supply fitting, the operation member can only be attached to the back surface of the water supply fitting, and the user of the remote operation type drain plug device needs to walk around the body of the water supply fitting to reach the back surface, which is inconvenient to use.

The water supply fitting and the operation member are vertically disposed in the fitting mounting hole, and the water supply fitting and the operation member are disposed in the fitting mounting hole. In this configuration, since both the water supply fitting and the operating element extend upward from the fitting mounting hole, the water supply fitting becomes an obstacle when the operating element is operated.

The above problem can be solved if the operation member and the water supply metal fitting are provided to different positions and operated. However, in this case, it is necessary to provide an operation unit hole separate from the metal fitting attachment hole in the flange portion of the bathtub or in the floor surface of the bathtub.

In this case, basins and tables such as a bathtub and a washbasin need to be processed on the premise that a remote operation type drain cock device is used, resulting in an increase in the workload of design and construction.

Also, in recent years, in washbasins, so-called vessel-type washbasins are increasingly used, which have a structure in which a basin, which occupies at least eighty percent of the total height, is provided on the top surface of a base.

In the conventional washbowl, the built-in washbowl has a structure in which a basin portion of the washbowl is disposed below a top surface of a base with respect to an opening of the base, and a flange portion disposed at an edge of the basin is fixed to the opening of the base. The under-counter washbasin is structurally characterized in that an opening of the washbasin is arranged below an opening of a base, and all basin bodies of the washbasin are positioned below the top surface of the base (counter). In contrast to the built-in, counter-top, container-style washbasins are constructed so that most of the basin rests on the base, with no portion below the top surface of the base, or only the drain opening below the basin and its vicinity below the top surface of the base. In this vessel-type washbasin, since most of the basin is located above the top surface of the base, the freedom of the selection and installation position of the washbasin part is higher than that of the built-in type and the under-counter type.

Specifically, in both the built-in and the under-counter type, the base opening and the washbasin opening must be matched, thus requiring adjustment of both the base and the washbasin during the design phase; the container-type structure is a simple placement of the washbasin, including the basin portion, on the base, which does not need to be precisely matched with the washbasin opening.

Therefore, there is an advantage in that the washbasin can be freely selected according to the user's taste, but there is a problem in how to form the hole for the operating unit. If mounting holes for the operation unit are provided in both the washbasin and the base, one of the holes is always open, resulting in a problem of deteriorated design and the like. On the other hand, if neither the washbasin nor the base is provided with the mounting hole for the operating unit, it is difficult to employ the remote-operated drain cock. It is also possible to use a washbasin which is not provided with a hole for the operating unit, and to open a hole with a drill or the like on a base which is not provided with a hole for the operating unit, but these methods may not be used if the base is made of ceramics or the like.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present invention provides a remotely operated drain plug device which improves the usability when an operating unit is provided on a water supply metal fitting, in order to improve the degree of freedom in the installation, structure and operation method of the operating unit.

The technical scheme adopted by the utility model is as follows:

a remote operation type drain cock device comprises an operation unit, a basin body drain port which is switched on and off according to the operation of the operation unit, and an action transmission component which transmits the operation of the operation unit to one side of the drain port; the operation unit comprises an operation unit body fixedly arranged on the basin body or an operation unit mounting surface beside the basin body and an operation piece for controlling a water outlet switch driven by the operation unit; the connection position of the action transmission component and the operation piece is positioned outside the operation unit installation surface.

Compared with the prior art, the remote operation type drainage bolt device has the advantages that the connection position of the operation piece of the operation unit and the action transmission component is positioned outside the installation surface of the operation piece, so that the degree of freedom of the installation layout and the operation method of the operation piece is improved. Specifically, it is no longer necessary to mount or manipulate the operation member in the operation member mounting hole, such as mounting the operation member horizontally with respect to the mounting surface of the operation unit, moving the operation member horizontally with respect to the mounting surface of the operation unit for manipulation, and the like, thereby improving the degree of freedom of the mounting and operating method

The term "outside the operation unit attachment surface" as used herein means that the drain plug device is positioned on the side close to the operation position of the operation unit when the user normally uses the drain plug device operated by a remote operation.

For example, the operation unit is arranged on the inner surface of the pot body, and when the operation is carried out from the inner side of the pot body, one side of the inner surface of the pot body is the outer side; the operating unit is arranged on the outer surface of the pot body, and when the operation is carried out from the outer side of the pot body, one side of the outer surface of the pot body is the outer side; the operating unit is arranged near a roughly horizontal surface, such as the horizontal surface around the opening of the pot body or the periphery of the pot body on a base for placing the pot body, and when the operation is carried out from the upper part of the pot body, one side of the top surface of the opening edge of the pot body is the outer side; the operation unit is attached to a vertical surface, for example, a vertical panel provided near the bowl, and when the operation unit is operated from the front of the vertical surface, the front side (the side close to the body) of the vertical surface is the outside.

Furthermore, the operation unit body of the remote operation type drainage bolt device is used as a water supply metal fitting of the basin body.

In the remote operation type drain cock device, since the operation member is used as the water supply metal fitting, it is not necessary to additionally provide the operation member mounting hole for the operation member. Further, when the conventional water supply fitting is used as an operation tool, the operation tool needs to be attached upward from the fitting attachment hole like the water supply fitting, and the water supply fitting has to be an obstacle to the operation tool. In the utility model, the connecting position of the operating part and the action transmission assembly is positioned outside the operating part mounting surface, so that the degree of freedom of the mounting and operating method of the operating part is improved. For example, a rotary handle type operation element is attached to a side surface of the water supply fitting, or the operation element is provided in front of the water supply fitting and pushed and pulled in a direction parallel to the operation element attachment surface.

The term "operation unit attachment surface" as used herein refers to an attachment surface of a water supply metal fitting as an operation unit body.

Furthermore, the operation unit of the remote operation type drainage bolt device is positioned on the water supply metal fitting of the drainage equipment, and most of the pot body in the drainage equipment where the water supply metal fitting is positioned is placed on the base.

The drain equipment, such as the structure that most of the basin bodies such as a container type basin body are arranged on the top surface of the base, can solve the problems generated by the installation structure of the operating part body when the basin body with the structure is adopted, such as the operating part is arranged on the basin body or the base.

Further, the motion transmitting assembly of the remotely operated drain plug assembly is formed of a metal release wire including a tubular outer tube and an inner wire passing in and out of the outer tube.

Thereby defining the structure of the motion transfer component.

Further, in the remote operation type drain plug device, the operating member is a rotating handle, and the drain port is opened and closed by the rotating handle.

Thereby specifying the method of operation of the operating assembly.

Alternatively, in the remote-operated drain plug device, the operating member is a button, and the opening/closing of the drain port is alternately performed every time the button is pressed to open or close the drain port.

For a better understanding and practice, the utility model is described in detail below with reference to the accompanying drawings.

The end of the outer tube 5a of the release wire 5 is fixed to the wire fixing portion 4c, and the end of the outer tube 5a is fixed to the operation connection port K1 by the wire fixing portion 4c being fixed to the operation connection port K1 located in the water supply fitting K.

After the attachment, the wire fixing member 4c of the operation element 4 is fixed to the operation element connection port K1.

Also, the knob 4a is connected to the wire fixing member 4c and is rotatable but not movable in the axial direction. Also, the external thread of the access member 4b is screwed with the internal thread of the knob 4a and a part is not rotatable with respect to the wire fixing member 4c but is accessible in the axial direction.

Through the structure and the connection, after the installation is finished, when the knob 4a is turned, the spiral structure enables the inlet and outlet piece 4b and the inner metal wire 5b to advance towards the valve body component 2 or retreat towards the knob 4 a. In this embodiment, when the knob 4a is turned toward the body side, the inlet/outlet 4b and the inner wire 5b move forward to open the drain port 1a, and when the knob 4a is turned inward, the inlet/outlet 4b and the inner wire 5b retreat to close the drain port 1 a.

The valve body assembly 2 includes a disk-shaped valve body 2a for closing the drain opening 1a, a valve shaft 2b hanging downward below the center of the valve body 2a, and a guide 2c provided on the valve shaft 2b to prevent the valve body 2a from tilting.

Further, still be equipped with layer board nut N and drain pipe T as other spare parts, layer board nut N is equipped with the internal thread that is used for with the external screw thread threaded connection of outlet body 1, and drain pipe T is connected to the underground piping from adapting unit 6 lower extreme, and its body bends into S-shaped in order to form the water seal.

The washbasin constructed as described above and the drain pipe using the remote-operated drain cock device are installed as follows.

Further, even if not specifically described, the parts may be connected to each other in a waterproof manner by wrapping or bonding as appropriate as necessary.

First, the washbasin B is fixed on the base C1 on the top surface of the box C. At this time, the bottom surface of the washbasin B, in which the mounting hole B3 of the bowl portion B1 is located, is set in the duct opening C2 on the base C1.

Since the lower end of the side wall B2 of the washbasin B is located at a position slightly higher than the bottom surface of the drain port 1a of the bowl portion B1, by disposing the washbasin B on the base C1 of the cabinet C as described above, as shown in FIGS. 1 and 2, most of the washbasin B, specifically, a portion of about eighty percent of the total height, is disposed on the base C1.

Then, after the end portion of the outer tube 5a on the side close to the operating member 3 is fixed to the wire fixing member 4c, the inner wire 5b is pulled and connected to the in-out member 4b of the operating member 4. After the connection, the front end of the inlet/outlet member 4b is inserted into the wire fixing member 4c, and the wire fixing member 4c is fixedly attached to the operation member connection port K1.

Next, a knob 4a as a part of the operating member 3 is screwed to the access member 4b and connected to the wire fixing member 4 c.

In the case of abnormal use, for example, when parts need to be attached or detached for maintenance or the like, the knob 4a is manually pulled outward by force to release the connection, and the knob 4a, the inlet/outlet member 4b, and the like are removed from the water supply fitting K.

Next, the water supply metal fitting K is mounted to the metal fitting mounting hole C3 of the base C1 in the case C. At this time, the pipe end of the water supply metal fitting K for supplying water and the release wire 5 are disposed into the case C through the metal fitting mounting hole C3.

Next, the outlet body 1 is inserted into the mounting hole B3 of the washbasin B and screwed into the pallet nut N, and the edge of the mounting hole B3 of the washbasin B is clamped by the flange 1B and the upper surface of the pallet nut N, so that the outlet body 1 is mounted on the washbasin B.

Next, the end portion of the inner wire 5b on the side of the drain opening 1a is passed through the insertion portion 6b of the joint assembly 6 and pulled out laterally from the upper side of the straight pipe portion 6a, releasing the end portion of the outer pipe 5a of the wire 5 from being fixed to the stay 8.

Next, the stay 8 is fitted to the upper end of the straight pipe portion 6a, and the end of the insertion portion 6b is blocked by the cover 5 d.

Next, the upstream end portion of the straight pipe portion 6a of the connecting member 6 is connected to the lower end of the drain opening body 1, and the downstream end portion of the connecting member 6 is connected to the drain pipe T. And the downstream end of the drain pipe T is connected to the underground pipe on the lower sewer side.

In the present embodiment, the connection position of the operating element 4 and the motion transmission member is the connection position of the advance/retreat element 4b and the inner wire 5 b. Since the inlet/outlet 4b and the inner wire 5b are connected above the top surface of the base C1, the remote operation type drain plug device of the present embodiment is a remote operation type drain plug device in which the position where the operation member 4 is connected to the operation member is located outside the operation member installation surface.

The method of using the washbasin in the above embodiment will be explained below.

When water is supplied into the washbasin through the water supply metal fitting K, the right water supply operation handle H in figures 1 and 3 is rotated, so that water can be supplied while adjusting the flow rate and temperature of the water supplied from the water supply metal fitting K.

When the drain port 1a is opened and closed by remote operation, as shown in fig. 6(b), the valve body is first lowered, and the valve body 2a is brought into contact with the edge of the drain port 1a so that the drain port 1a is closed. At this time, as shown in fig. 6(a), the inlet/outlet 4b and the inner wire 5b are positioned to retreat toward the knob 4 a.

In this state, the knob 4a of the operating element 4 provided in the water supply fitting K is turned to the body side, and as shown in fig. 7(a), the inlet/outlet member 4b and the inner wire 5b advance toward the drain port 1a side by the spiral structure composed of the knob 4a and the inlet/outlet member 4b, and the rod portion 5c located at the lower end of the valve shaft 2b rises and pushes up the valve shaft 2b, so that the valve body 2a rises with the valve shaft 2b and is separated from the drain port 1a, and as shown in fig. 7(b), the drain port 1a is opened.

When warm water is present in the basin body portion B1 of the washbasin B, the warm water is discharged from the drain port 1a to the lower drain side through the inside of the drain port body 1, the connecting member 6, and the drain pipe T.

In this state, the knob 4a provided in the water supply fitting K is turned inward, the inlet/outlet member 4b and the inner wire 5b are retracted toward the knob 4a by the screw structure composed of the knob 4a and the inlet/outlet member 4b, the rod portion 5c located at the lower end of the valve shaft 2b is lowered, the lower end of the valve shaft 2b is released from the support, the valve body 2a is lowered together with the valve shaft 2b, and the valve body 2a is brought into contact with the edge of the drain port 1a to close the drain port 1a, thereby returning to the state shown in fig. 6 (b).

Thereafter, the drain port 1a can be opened and closed by remote operation at a position apart from the valve body 2a by turning the knob 4a of the operation unit 3.

In the remote operation type drain cock device of the first embodiment, the operation unit 3 is provided with the knob 4a having the same shape as the water supply operation handle H and used for manipulation at a position symmetrical to the water supply operation handle H with the pipe body portion of the water supply metal fitting K as the center by setting the connection position of the operation element 4 and the release wire 5 as the motion transmission means at the outside of the top surface of the base C1 to which the water supply metal fitting K as the operation unit body 9 is attached, so as to improve the design.

Further, the water supply operation knob H and the knob 4a for water supply operation are operated by turning, and there is no inconvenience in use.

Further, since the water supply fitting K is provided as the operation unit body 9, the opening for mounting the operation unit body 9 can be used as the fitting mounting hole C3 as well, without additionally opening an opening dedicated to mounting the operation unit body 9.

Therefore, even if the washbasin B which is specially used for installing the opening of the operating assembly body 9 is not arranged, the box body C can use the remote-operated drainage bolt device, thereby expanding the selection range of the washbasin B.

Next, a second embodiment of the present invention will be described with reference to the drawings.

Since the second embodiment of the present invention is the same as the first embodiment except for the configuration of the operation unit 3, only the operation unit 3 having a different configuration will be described below, and the description of the other configurations will be omitted.

As shown in fig. 8 and 9, in the second embodiment, the operation unit 3 of the remote operation type drain cock device includes an operation member 4 and a water supply metal fitting K, the operation member 4 is composed of a mechanism part 7, a button 4d and a wire fixing member 4c, and the water supply metal fitting K is the operation unit body 9 as in the first embodiment.

The mechanism portion 7 is composed of a shaft-shaped lock shaft 7a and a cylindrical mechanism body 7b accommodating the lock shaft 7a therein, and a thrust lock mechanism is installed therein, and switching is repeated in which the lock shaft 7a advances and locks/unlocks and the lock shaft 7a is pushed by stress to retreat each time the lock shaft 7a is pressed.

The push button 4d is a disk-shaped member, and its center is connected to the lock shaft 7 a.

The wire fixing member 4c is formed of a substantially cylindrical member, and is fixed to the operating element connecting port K1 so that the end of the lock shaft 7a of the mechanism portion 7 is opposed to the end of the inner wire 5b, for fixing the mechanism portion 7 and the end of the outer tube 5 a. Further, a cylindrical portion is provided to cover the push button 4d and the side surface of the mechanism portion 7. The cylindrical portion is located at a position symmetrical to the water supply operation handle H with the pipe body portion of the water supply metal fitting K as a center, and has the same shape as the water supply operation handle H to improve the design of the operation member 3.

The end of the outer tube 5a of the release wire 5 is fixed to the wire fixing member 4c, and the wire fixing member 4c is fixed to the operation member connection port K1 to which the water supply fitting K is attached, so that the end of the outer tube 5a of the release wire 5 is fixed to the operation member connection port K1.

And, although not shown in the drawings, the release wire 5 is provided with a return spring that pushes the inner tube 5b toward the operating assembly 3.

In the second embodiment, one end of the lock shaft 7a of the mechanism portion 7 is fixed to the disc-shaped push button 4d, and the other end of the lock shaft 7a of the mechanism portion 7 is connected to the end of the inner wire 5 b. Further, the mechanism body 7b of the mechanism portion 7 is attached to the water supply metal fitting K by the wire fixing member 4 c.

Other structures are the same as those of the first embodiment except for the above structure.

In the structure of the second embodiment, the water supply fitting K is the operation unit body 9, the installation surface of the operation unit body 9 is the top surface of the base C1, and the outer side of the installation surface of the operation unit body 9 in this embodiment is the side above the top surface of the base C1. The connection position between the operating element 4 and the operation transmitting member of the second embodiment is the connection position between the lock shaft 7a and the inner wire 5 b. In the present embodiment, the inner wire 5b is urged toward the operating unit 3 by the return spring so as to be held in abutment with the lock shaft 7a which is a part of the operating element 4. Therefore, in the remotely operated drain plug device of the second embodiment, since the lock shaft 7a is connected (abutted) to the inner wire 5b above the top surface of the base C1, the remotely operated drain plug device of the second embodiment is a remotely operated drain plug device in which the connection position of the operation transmission member and the operation element is located outside the operation member installation surface.

When the remote-operated drain plug device of the second embodiment is used, as shown in fig. 8(b), the valve body 2a and the valve shaft 2b of the valve body assembly 2 are first lowered, and the drain port 1a is closed. As shown in fig. 8(a), at this time, the inner wire 5b retreats toward the push button 4d, and the lever portion 5c descends. In this state, when the push button 4 of the operation element 4 is pushed, the thrust lock mechanism is operated, and as shown in fig. 9(a), the lock shaft 7a and the inner wire 5b abutting against the lock shaft 7a advance toward the drain opening 1 a.

As the inner wire 5b advances, the stem portion 5c rises, and the valve body 2a is separated from the edge of the drain port 1a by pushing the valve shaft 2b and the valve body 2a, whereby the drain port 1a is opened as shown in fig. 9 (b).
