Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sanitary cleaning device that is attached to a flush toilet and performs private parts cleaning, etc., and more specifically relates to a valve unit installed in a cleaning water supply piping system.

[Conventional technology]

BACKGROUND ART In recent years, sanitary cleaning devices for cleaning private parts, etc., in which a casing containing a built-in functional part is integrally fixed to a toilet bowl body have rapidly become popular. This sanitary cleaning device has a hot water tank with a built-in heater for storing hot water for cleaning, a nozzle device for spouting hot water from the hot water tank to private areas, etc. built into the casing. The supply of hot water for washing is carried out by opening and closing the washing water flow path, including valve units, etc., using an external operation panel.In addition, a control system for operating hot air fans for drying, etc. It may also be equipped with.

[Problem that the invention attempts to solve]

By the way, such a sanitary cleaning device is designed as a product to be installed in a general toilet, so it cannot be directly applied to, for example, a Western-style unit bath that requires maximum use of a narrow space. For this reason, it is possible to adopt as one effective means to separate the attached cleaning function unit attached to the toilet main body from the function unit including the cleaning warm water supply and all operation control systems.

Furthermore, when the installation space is limited in this way, it is also a design condition to reduce the capacity of the divided functional sections, and it is necessary to perform a design that satisfies this requirement.

In addition to these design conditions, the smaller equipment capacity will inevitably have a major impact on equipment assembly, and it will be necessary to change the overall equipment design, including the ease of assembly of each equipment. . For example, in order to install a valve unit that supplies wash water to a hot water tank, it is necessary to connect a hose etc. in addition to fixing the unit itself, and as a result, it cannot be manufactured without going through two steps. In addition, the work of connecting hoses in a small device capacity is extremely complicated, and there are also problems such as not being able to achieve sufficient sealing pressure, resulting in water leakage.

Therefore, in consideration of the above-mentioned problems caused by the miniaturization of device capacity, the present invention simplifies the assembly of the valve unit placed in the function box.
The purpose is to suppress the decline in assembly work efficiency and productivity due to downsizing of equipment capacity.

[Means for solving problems]

In order to achieve the above object, the present invention provides a valve unit installed in a piping system that supplies cleaning water to a nozzle device of a sanitary cleaning device, in which a piping connection portion of the valve unit is attached to a mounting plate that fixes the valve unit. The socket is provided with a protruding fixed seat for receiving the socket, and a socket whose outer surface is pressed by the fixed seat is connected to the connecting pipe, and the socket is externally fitted onto the pipe connecting portion.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

Fig. 1 is a side sectional view of a functional box for sanitary cleaning equipment equipped with a valve unit according to the present invention;
The figure is a plan view of functional boxes arranged in a Western-style unit bath.

In Figure 2, inside the Western-style unit bath A,
A bathtub B, a washbasin C, and a flush toilet D are arranged as a unit, and a washing section E having washing and drying functions is attached to the rear side of the flush toilet D. The function box 1, which contains the supply of hot water for washing to the washing section E and the control section for each function, is located behind the flush toilet D to effectively utilize the narrow space inside the Western-style unit bath A. It is placed in the cabinet G below the integrated counter F. Further, among the various specifications of the Western-style unit bath A, if there is something that cannot be stored in the cabinet G or if there is no cabinet G, it can be placed behind or to the side of the flush toilet D.

Note that the cleaning section E is of a conventionally used type, and is provided with a nozzle device inside thereof that moves forward and backward in the direction of the bowl of the flush toilet D and jets hot cleaning water from the cleaning position. Some also have a built-in warm air fan for drying after the cleaning process.

As shown in FIG. 1, the function box 1 includes a lower casing 2 for housing equipment, an upper casing 3, and a connector cover 4 detachably attached to one side of the lower casing. A support plate 5 is fixed in the lower casing 2 in a substantially horizontal direction, and a control board 6 and a mounting plate 7 for a valve unit are connected to the upper and lower parts of the support plate 5, respectively.

A hot water tank 8 for heating and storing wash water is fixed to the support plate 5, and a valve unit 9 for supplying wash water to the hot water tank 8 is arranged on one side of the lower mounting plate 7. The hot water tank 8 has a built-in heater, a sensor for temperature control, a float switch for preventing dry heating, and the like. Further, the valve unit 9 is connected at its inlet side to a steel pipe 10 communicating with a cleaning water source, and has a supply pipe 11 connected to the hot water tank 8 at its outlet side.

The heating system of the hot water tank 8 and the opening/closing of the flow paths of the valve unit 9 are controlled by a control section 12 provided on the control section board 6. That is, all control elements included in the cleaning process, such as setting the temperature of hot water in the hot water tank 8 and opening time of the flow path by the valve unit 9, are controlled by the control section 12.

With the above-described cleaning water supply system including the hot water tank 8 and the valve unit 9, when the valve unit 9 receives a signal from the control section 12 and opens its internal flow path,
Cleaning water flows into the hot water tank 8. Thereby, heated hot water is supplied from the hose 13 communicating with the nozzle device of the cleaning section E, and cleaning water can be spouted from the nozzle device.

Note that when using a sanitary cleaning device, it is of course possible to provide the operation panel integrally with the function box 1, but from the standpoint of usability, we have chosen an example in which the operation panel P is placed on the wall of the Western-style unit bath A. This will be shown in the examples. By using this operation panel P, functions such as firing the flushing water discharge operation, hot air drying, heated toilet seat, etc. can be added. and the control section 12 of the function box 1.

Function box 1, which is equipped with the elements necessary for the above-mentioned washing process and a control system for the operation of washing section E, is a counter F integrated with washbasin C of Western-style unit bath A.
It is used by placing it on the floor inside the cabinet G located at the bottom of the cabinet. Alternatively, it can be placed on the floor of the Western-style unit bath A behind or to the side of the flush toilet D. For this purpose, leg portions 20 are integrally formed on the lower surface of the lower casing 2. Furthermore, a fixing fitting 21 for fixing the function box 1 to the side wall of the Western-style unit bath A or other equipment is provided at the lower part of the back.

5 is a perspective view of the function box 1 housed in a cabinet G provided at the bottom of a counter F. FIG. In this case, since function box 1 is not placed on the floor of Western-style unit bath A,
Sufficient waterproofing measures can be taken against water splashing from the bathtub B and washbasin C, and accidents such as electrical leakage can be prevented. Furthermore, the function box 1 can be used safely without tripping over it, and the space inside the narrow Western-style unit bath A can be used effectively. Furthermore, when the walls of the Western-style unit bath A are to be finished with tiles H, the operation panel P is shaped in front of the tiles H as shown in the figure, and arranged so that joints I are formed. In this way, by making the operation panel P harmonious with the surrounding walls, it is possible to improve the function and appearance of the unit.

FIG. 3 is an exploded perspective view showing the valve unit 9 and the mounting plate 7.

On one surface of the mounting plate 7, fixing seats 25 having a U-shaped cross section for fixing the valve unit 9 are formed at two positions, and a receiving seat 27 with a screw hole 26 is provided. An oval notch 28 is formed at the tip of the fixed seat 25, and a rib 29 for positioning the valve unit 9 is provided on the outer circumferential surface of the catch 27 so as to protrude from the tip of the seat 27. ing. In addition, a seat 15 and a screw hole 16 are formed to support and fix the motor unit 14 that mechanically opens and closes the needle valve in the valve unit 9, and an engaging pawl is provided at the upper end for temporarily fixing it to the support plate 5. There are 17.

The valve unit 9 includes an inflow section 30 that connects to a steel pipe 10 that communicates with a washing water source, an outflow section 31 that connects a supply pipe 11 that goes to the hot water tank 8, and a waste water section 32 that is provided as a countermeasure against insensitive water volume. It is something. A male screw 3 is provided on the outer periphery of the inflow portion 30.
3 is formed, and the steel pipe 10 is connected by a cap nut 10a.

In addition, the outflow part 31 and the water waste part 32 are connected to the fixed seat 25.
A socket 34 integrally formed with a large diameter part 35 located on the inside side and a small diameter part 36 located on the outside side.
is detachably fitted on the outside. Furthermore, O-rings for sealing are attached to the outer peripheries of the outflow portion 31 and the water waste portion 32, so that sealing can be achieved between them and the inner periphery of the large diameter portion 35 of the socket 34.

The above valve unit 9 is assembled to the mounting plate 7 in the following manner.

First, the sockets 34 are fitted into each of the outflow section 31 and the water waste section 32 to integrate them, and in this state, both sockets 34 are set so as to fit inside the fixing seat 25 as shown in FIG. Note that the sockets 34 are attached to the steel pipe 10 and the supply pipe 11 in advance, respectively. When the socket 34 is set on the fixed seat 25, the small diameter portion 36 of the socket 34 is attached to the fixed seat 25, as shown in the cross-sectional view on the outflow portion 31 side in FIG.
At the same time, the step between the large diameter portion 35 and the large diameter portion 35 comes into contact with the inner wall of the fixed seat 25 . Note that the socket 34 is attached to the fixed seat 25 in the same manner on the water waste portion 32 side.

Here, the distance between both fixed seats 25 is determined by the distance between both sockets 3.
If the sockets 34 are set appropriately in accordance with the distance between the sockets 4 and 4, the sockets 34 will mutually receive acting forces toward the center of the valve unit 9. Therefore, the valve unit 9 is fixed in position by the fixing seat 25 by the reaction of this acting force.

Note that the O-ring 37 and the large diameter portion 3 of the socket 34
The seal between the 5 inner circumferences is determined by the degree of fitting between the large diameter portion 35, the outflow portion 31, and the water waste portion 32. Therefore, the acting force that the socket 34 receives from the fixed seat 25 toward the center of the valve unit 9 has nothing to do with the sealing pressure, and even if the fixing strength is small, water leakage will not occur.

Next, the valve unit 9 placed in a predetermined position
On the other hand, by screwing the screw 40 into the screw hole 26 of the receiving seat 27, the valve unit 9 is fixed to the mounting plate 7. Then, attach the steel pipe 10 to the cap nut 10a.
The assembly is completed by connecting it to the inflow portion 30 by.

[Effects of the invention] As explained above, in the valve unit of the present invention, when attaching the valve unit to the mounting plate, the valve unit itself is fixed to the mounting plate at the same time as connecting the piping to the outflow section and the drainage section. can. Therefore, assembly work is simplified and productivity can be improved. Furthermore, since the valve unit can be installed even if there is no space required for piping connections, there is no problem in assembly even if the device capacity is small.
