[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to improvement of a Western-style toilet with a toilet bowl, and more specifically, to stop hand-washing water in the toilet bowl when a user sits on the toilet bowl. It is related to a Western-style toilet with a washbasin.

(Prior Art) Generally, in a Western-style toilet with a toilet, for example, as shown in FIG. 7, a water tank 3 is installed in the vicinity of a stool-type toilet 2.
The upper part of the water storage tank 3 is a hand washing device 4 through which the hand washing water W is discharged. Then, by operating the switch board 6 (which may be a lever), the water stored in the water tank 3 is discharged to the toilet bowl 2 to flush the waste in the toilet bowl 2, and the hand washing water W is discharged from the water pipe 12 of the hand toilet bowl 4. The hand washing water W is stored in the water tank 3 below the hand washing device 4.
Is formed so as to be stored in.

(Problems to be solved by the invention) However, when the user of the toilet bowl 2 operates the switch panel 6 while seated on the toilet seat 26, the water stored in the water tank 3 is discharged to the toilet bowl 2 and the handwasher 4 is discharged. There was a problem that the hand-washing water W discharged from the water pipe 12 splashed by the hand-washing device 4 and the splashed water wets the seated user.

(Means for Solving Problems) The present invention has been improved in view of the above-mentioned problems of the related art, and when the user sits on the toilet seat, the handwash water of the handwasher is stopped directly. Water is supplied to the water tank to prevent water leakage of the user due to hand washing water, and when the user does not sit on the toilet seat, as usual, the water in the water tank is released into the toilet bowl and the hand washing water It is intended to provide a Western-style toilet bowl with a hand-washing device.

In order to solve the above-mentioned problems, the means adopted by the present invention is that a water tank is provided in the vicinity of a stool-type toilet bowl, and the upper part of the water tank is used as a hand-washing device for hand-washing water. In a Western-style toilet bowl that is stored in a tank and used as flush water for the toilet bowl when necessary, the pipeline for the supply water is connected to the pipeline that normally communicates with the toilet bowl to supply water for handwashing water. Normally, it is formed by a conduit that leads to the water tank via a closed on-off valve, while the toilet bowl is equipped with a seating detection switch that detects the seated state, and the seating detection switch detects the seated state of the user. In this case, the opening / closing valve is opened to stop the water supply to the hand wash basin and supply the water to the water storage tank.

(Operation) When the user sits on the toilet seat, the seating detection switch operates, the on-off valve opens, water supply to the hand wash is stopped, and water is directly supplied to the water tank.

When the user does not sit on the toilet seat, the seating detection switch does not operate, the open / close valve is closed, and water is supplied to the handwasher and handwashing water comes out. This hand wash water is stored in the water tank.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. The same members as those in the conventional example shown in FIG. 7 are designated by the same reference numerals.

FIG. 1 shows a Western-style toilet 1 with a hand-washing device in which a water tank 3 is provided in the vicinity of a stool type toilet 2, and an upper part of the water tank 3 is a hand-washing device 4 through which hand-washing water W is discharged.

The toilet bowl 2 is equipped with a local cleaning device, and the toilet bowl 2 having a predetermined shape is provided with a local cleaning device 5. The toilet bowl 2 is washed from the local cleaning device 5 by operating a switch panel 6 on the side of the toilet bowl 2. Water is gushing out.

The water storage tank 3 is arranged at a higher position than the toilet bowl 2, and a float valve 8 connected to a water supply pipe 7 is provided at an upper part of the water storage tank 3 and the float valve 8 is branched to guide water in two directions, up and down. A tube 9 is connected (see Figures 1 and 3).

The float valve 8 has the same structure as the conventional one, because the float 10 moves up and down by opening and closing the water level.
A drainage pipe for hand-washing is provided at the upward water inlet 11 of the branch pipe 9.
12 is connected and is guided above the handwasher 4. Branch pipe 9

In the water tank 3, a water stop ball 18 that is lowered by a chain line 16 to open and close a drainage port 17 and a water level pipe 19 that holds the water level are arranged in the same manner as in the conventional one.

Now, as shown in FIG. 2, there is a predetermined amount of water stored in the water tank 3, and when the switch panel 6 on the side of the toilet 2 is operated, the water ball is stopped via the electromagnetic solenoid 20. When 18 moves up or the lever 21 on the outer side of the water storage tank 3 is operated, the water stop ball 18 moves up via the chain line 22 and the stored water is discharged into the toilet 2 via the conduit 23.

On the other hand, when the stored water level is lowered, the float 10 is lowered and the float valve 8 is opened so that the water of the water supply pipe 7 enters the drain pipe 12 from the upwardly directed water inlet 11 of the branch pipe 9 and is used as hand-washing water W on the handwasher 4. Is discharged. The discharged hand-washing water W passes through the receiving surface of the hand-washing device 4 and enters the water tank 3 through the drop port 24 and is stored therein. When the pressure-sensitive switch of the toilet seat, which will be described later, is turned off, the electromagnetic solenoid 14 of the branch pipe 9 is actuated to open the downward water guide port 13 of the branch pipe 9, causing the water in the water supply pipe 7 to differ in water level. The water introducing port 13 causes the water to fall into the tank.

Further, as shown in FIG. 1, a water guiding pipe and a pressurizing means for guiding water to the local cleaning device 5 are provided inside and outside the water storage tank 3, and the local operation is performed by operating a switch panel 6 on the side of the toilet bowl 2. Hot water can be jetted from the nozzle of the cleaning device 5.

On the other hand, the upper end of the toilet bowl 2 is a toilet seat mounting surface, and a fixing member, which is a toilet seat box 25 in this example, is fixed to the rear portion of the toilet bowl 2. As shown in FIG. 4, the toilet seat 26 has the mounting pieces 26A on both sides of the rear end thereof arranged in the mounting recess 25A of the toilet seat box 25, and the pivots 27 are connected between the mounting piece 26A and the mounting recess 25A, respectively. It is placed on the toilet seat surface.

As shown in FIG. 5, the pivot 27 of the toilet seat 26 is inserted through a shaft hole 28 on the side of the mounting piece 26A of the toilet seat 26 and a longitudinal long hole 29 of the toilet seat box 25. It is fixed to 26A, and the pivot 27 can move up and down in the long hole 29 depending on the action of the seating load applied to the toilet seat 26. The pivot 27 passes through the long hole 29 and is inserted into the toilet seat box 25 by a predetermined length. Reference numeral 30 denotes a cylindrical washer, which is inserted from the outer surface of the long shaft hole 29 to the tip end side of the pivot 27.

The portion of the pivot 27 inserted into the toilet seat box 25 is

A coil spring is vertically formed around the guide shaft 33 between the coil spring and the bottom surface 32 in the space 25. The lower end of the guide shaft 33 is fixed to the bottom surface 32 of the toilet seat box 25, and the upper end of the guide shaft 33 is at the same height as the lower end of the long shaft hole 29, and the lowering of the pivot 27 is received at this position. Reference numeral 34 is a guide tube for guiding the upper and lower outer peripheral portions of the coil spring.

The pivot 27 is inserted in each symmetrical position on both mounting pieces 26A of the toilet seat 26, and a seating detection device 35 for detecting the seating load of the toilet seat 26 is provided on one of the pivots 27 side, as shown in FIG. It is installed.

The seating detection device 35 is interposed between the inner peripheral surface of the toilet seat box 25 and the pivot 27, has a cylindrical casing 36 that is open at the lower surface and is fixed to the inner periphery of the toilet seat box 25, and the upper and lower parts formed of rubber or the like. The elastic outer skins 37, 38 are formed of an auxiliary electrode 39, a pressure-sensitive conductive rubber 40, and a pressure-sensitive switch 43 having contacts 41, 42 mounted thereon. The lower end side of the elastic body outer skin 38 is a contact surface portion that makes surface contact with the pivot shaft 27. The pressure-sensitive switch 43 is formed in a cylindrical shape in this embodiment, is housed in a casing, and its wiring is provided by an elastic outer skin 37 and an opening (not shown) formed in the side surface of the casing 36 to form a toilet seat. It is designed to be led out to the circuit section in the box 25.

Since the pivot shaft 27 is located at the upper end side of the long shaft hole 29 by the spring force of the spring means 31 without a toilet seat load, the elastic body skins 37 and 38 of the pressure-sensitive switch 43 are moved by the raised pivot shaft 27. It is pressed upward. For this reason,
The pressure-sensitive conductive rubber 40 of the pressure-sensitive switch 43 is made conductive by sensing the pressing force, and the contacts 41 and 42 are made conductive, and the pressure-sensitive switch 43 is held in the ON state. This pressure sensitive switch 43
Is turned off in the circuit portion in the toilet seat box 25 so that it is not energized and the electromagnetic solenoid 14 of the branch pipe 9 does not work (the downward water inlet 13 of the branch pipe 9 is closed). State, see FIG. 3).

On the other hand, the pivot 27 on which the toilet seat load acts is lowered to the lower end side of the long hole 29 against the spring force of the spring means 31, and the pressure sensitive switch 43.
The elastic outer skins 37, 38 return to their original state when the pressure is released and there is no load. Therefore, the pressure-sensitive conductive rubber 40 of the pressure-sensitive switch 43 is in a non-conductive state, and the contact 41
And 42 are opened and the pressure sensitive switch 43 is held in the OFF state.
The OFF state of the pressure-sensitive switch 43 is turned ON so that the circuit portion in the toilet seat box 25 is electrically reverse-converted and energized, and the electromagnetic solenoid 14 of the branch pipe 9 acts to open / close the valve.

That is, when the user does not sit on the toilet seat 26, the pressure sensitive switch 43 of the seating detection device 35 is in the ON state, the downward water inlet 13 of the branch pipe 9 is closed by the opening / closing valve 15, and the toilet seat Pressure switch when user is seated on 26
When 43 is turned off, the downward water inlet 13 is opened.

Then, when the user seated on the toilet seat 26 operates the switch panel 6 to discharge the water stored in the water tank 3 to the toilet bowl 2 as necessary, the water in the water supply pipe 7 passes through the drain pipe 12 and the handwasher 4 The water is directly stored in the water storage tank 3 through the downward water introduction port 13 (see FIG. 6).

As described above, since the hand-washing water W does not come out, the conventional inconvenience of wetting the seated user by splashing the hand-washing water W does not occur.

When a user who does not sit on the toilet seat 26 operates the switch on the switch panel 6 or operates the lever 21 on the outer surface of the water tank 3 to discharge the water stored in the water tank 3 to the toilet 2, the water in the water supply pipe 7 is drained. After passing through the pipe 12, it becomes the hand-washing water W, which falls into the tank through the receiving surface of the hand-washing device 4 and the dropping port 24 and is stored therein.

In the embodiment described above, the seating detection is performed by the seating detection device.
Although the pressure-sensitive switch 43 of 35 is used, a seating detection switch for detecting seating may be a proximity switch, a capacitance type proximity switch, a photoelectric tube type switch, an ultrasonic sensing type switch, or the like. . Further, the toilet 2 is not limited to the shower cleaning type of this example,
It may be a type without a shower device.

(Effect of the Invention) Since the present invention is the means for solving the problems described above, the intended problems can be solved. That is, the present invention has a structure in which when the user sits on the toilet seat, the handwash water of the handwasher is stopped and the water is supplied directly to the water tank, so that the user sitting on the toilet seat needs to store the water in the water tank. Even if water is discharged into the toilet bowl, the water supply to the water tank does not come out of the drain pipe of the handwash device, and the seated user does not suffer from the inconvenience caused by splashing of the handwash water. In the present invention, when the user does not sit on the toilet seat, the handwash water is discharged to the handwasher and water can be washed by hand when the water in the water storage tank is discharged to the toilet bowl, and the handwash water is stored in the water tank.
