Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a sanitary washing device mounted on or adjacent to the toilet bowl body.

(B) Conventional technology This type of sanitary cleaning device has a nozzle that discharges cleaning water inside the toilet bowl body, a water storage tank that stores the cleaning water and keeps it heated to an appropriate temperature, and a cistern that supplies the cleaning water to the water storage tank. A plurality of solenoid valves are provided between the water supply pump, the water storage tank, and the nozzle. Such a prior art is disclosed in Japanese Utility Model Application No. 58-44990, but the above-mentioned nozzle is normally configured to be switchable between a ladies' nozzle that protrudes deeply into the toilet body and a family nozzle that protrudes shallowly. This switching is performed by opening and closing the electromagnetic valve provided on the corresponding side depending on the wishes of the ladies' or family's use. This kind of nozzle has fewer solenoid valves, which simplifies piping, but it also has many moving parts, making it more complicated.Also, when not in use, all solenoid valves must be closed to prevent water leakage, making the electrical circuit complicated. It was hot.

(c) Problems to be solved by the invention The invention aims to improve the ease of assembling the main body of the washer and shorten the length of the water supply pipe.

(d) Means for solving the problem The present invention includes a nozzle that has flow channels for families and women and discharges washing water from the selected flow channel, a water storage tank for washing water, and a washing water tank in the tank. a water supply pump that supplies water; a first solenoid valve for a main valve connected to the water storage tank; a second solenoid valve provided between the first solenoid valve and the family flow channel; and the first solenoid valve. It has a third solenoid valve installed between the women's flow channels, and the respective solenoid valves are connected by a water supply pipe, and the first solenoid valve, the second solenoid valve, and the third solenoid valve are a single solenoid valve. The electromagnetic valve assembly is fixed to the fixed plate, and the assembly is fixed near the nozzle.

(E) Operation The first solenoid valve for the main valve, the second solenoid valve for the family, and the third solenoid valve for the ladies are each fixed to a single mounting plate to form a unit and fixed near the nozzle. The first solenoid valve is opened to supply water to the nozzle, and the second or third desired solenoid valve is opened to discharge cleaning water to the area to be cleaned.

A dryer main body 5 is installed inside to dry the part to be cleaned by blowing hot air afterwards.

The cleaning device main body 4 will be explained in detail. 6 is the toilet bowl body 1
It is a cylindrical nozzle that discharges cleaning water toward the approximate center of the inside, and as shown in FIG. 8b
two inner cylinders 9a and 9b formed with a
a and 10b, and disposed between a sliding tube 12 having discharge holes 11a and 11b bored at the tips of the respective flow channels, and the rear end of the side wall of the sliding tube and the tip of the inner wall of the outer tube 7. A spring 13 is energized so that the sliding cylinder 12 is always housed in the outer cylinder 7, and an inlet is fixed to the rear part of the outer cylinder 7 and communicates between the space 14 between the outer cylinder and the inner cylinder. It consists of a cap 18 provided with an opening 15 and two outlets 16 and 17. Reference numeral 19 denotes a water storage tank housed on one side of the cleaning device body 4, in which the cleaning water discharged from the nozzle 6 is supplied from the cistern 2, heated by an internal heater (not shown), and stored as hot water. 20 is the water storage tank 19
A water supply pump fixed to the side wall of the cistern supplies cleaning water in the cistern from the bottom of the water storage tank 19 via a water supply pipe 21 connected to the cistern 2. 2
Reference numeral 2 denotes a substantially square-shaped mounting plate fixed near the nozzle 6, on which a first electromagnetic valve 23, a second electromagnetic valve 24, and a third electromagnetic valve 25 are fixed.

The first solenoid valve 23 has an inlet side connected to a water supply pipe 26.
The outlet side is connected to the upper part of the water storage tank 19 through a water supply pipe 27 to the inlet 1 of the nozzle 6.
5, and from the water storage tank 19 to the nozzle 6
This is for the main valve that cuts off the water supply to the side.

The second solenoid valve 24 has an inlet side connected to a water supply pipe 28.
The outlet side is connected to one outlet 16 of the nozzle 6 through a water supply pipe 29 to a short flow channel 10a.
It is connected to the inner cylinder 9a that communicates with the water flow, and is suitable for families with strong water flow.

The third solenoid valve 25 has an inlet side connected to the water supply pipe 30.
The outlet side is connected to the other outlet 17 of the nozzle 6 through the water supply pipe 31 and connected to the long flow channel 10b.
It is connected to the inner cylinder 9b that communicates with the water flow, and is suitable for ladies with weak water flow.

The dryer main body 5 includes a duct 32 that discharges warm air to a substantially central portion of the toilet main body 1, a heater 33 disposed within the duct, and a fan 35 disposed within the duct and rotationally driven by a motor 34. It consists of

Next, we will discuss the operation. Now, when using it for family use, when the first solenoid valve 23 and the second solenoid valve 24 are opened and the water supply pump 20 is operated, the cleaning water in the cistern 2 is supplied to the water storage tank 19, and this water supply is used to supply water. The cleaning water that has flowed into the cavity 14 through the pipe 26, the first electromagnetic valve 23, and the inlet 15 is pushed against the spring 13 into the sliding tube 1.
After that, the cleaning water passes through the flow channel 10a and is gradually discharged from the discharge hole 11a. When the sliding tube 12 is pushed out, the cleaning water that has previously accumulated in the cavity 14 flows out from between the outer wall of the sliding tube 12 and the inner wall at the tip of the outer tube 7, and the cleaning water that has accumulated in the flow channel 10a in advance flows out. The cold water is discharged from the discharge hole 11a until the sliding tube 12 fully protrudes to the front (position A in broken line in FIG. 2) to prevent cold water from hitting the part to be cleaned.

When used for ladies, the first solenoid valve 23 and the third solenoid valve 25 are opened, and the sliding tube 12 is pushed out through the flow channel 10b to the position where it completely protrudes to the front side (at the position indicated by the broken line B in Fig. 2). ) Release hole 1
Released from 1b.

Therefore, unless the first electromagnetic valve 23 is opened, cleaning water will not be discharged in either the family or ladies use case.

(g) Effects of the invention As described above, the invention provides a solenoid valve by fixing the first solenoid valve for the main valve, the second solenoid valve for the family valve, and the third solenoid valve for the ladies valve to a single mounting plate. Since the first solenoid valve is constructed as an assembly, the first solenoid valve not only prevents water from leaking from the nozzle part when not in use, but also allows comprehensive management of each solenoid valve, and also simplifies assembly. Further, since the solenoid valve assembly is fixed near the nozzle, the water supply pipes connecting the respective solenoid valves and the water supply pipe connecting the solenoid valves and the nozzles can be shortened.
The piping is simplified, the amount of cleaning water remaining in the water supply pipe is reduced, and the amount of cold water discharged at the initial stage of use of the main body is also reduced.
