Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a toilet bowl with a hot water washing device, and more particularly to an improvement of a toilet bowl with a hot water washing device that supplies washing water through a flush valve to the toilet bowl. .

[Prior Art] Toilet bowls with a hot water washing device for ejecting hot water to the human buttocks are becoming popular. This toilet bowl with a hot water washing device is usually installed in a western-style toilet having a low tank, and the water supply to the hot water washing device is dispensed from a water supply path (for example, a ball tap) in the low tank.

By the way, there is an electric type flush valve for supplying flush water to a toilet bowl. An example of this remote control flash valve will be described with reference to FIG.

Reference numeral 10 is a valve casing, which has an inlet 12 and an outlet 14, and a piston main valve 16 is provided between them. The piston main valve 16 has an inner hole 18 passing through the inside thereof,
A sleeve-shaped piston guide part 20 with vertical ribs at its lower end
Is provided. This sleeve-shaped piston guide part
The vertical rib 20 is inserted through the opening 22a such that the peripheral surface of the vertical rib is slidable on the inner peripheral surface of the opening 22a of the partition wall 22.

A starting valve 24 is inserted in the inner hole of the piston main valve 16, and a valve shaft 24a of the starting valve 24 is inserted through the piston guide portion 20 and extends downward. Reference numeral 26 is a lever, and a push rod 28 is connected to the lever 26.
The start valve 24 can be tilted by contacting a. An opening is formed above the casing 10, and a cover cap 30 is screwed into the opening.

A seat portion 34 on which the start valve 24 is seated is provided around the inner hole 18 of the piston main valve 16 so as to project from the inner peripheral wall, and a rubber packing 36 is arranged on the upper surface side of the inner hole 18 of the piston main valve 16. 18
It is fixed by a press nut 38 screwed to the.
A compression coil spring 40 for urging the starting valve 24 downward is disposed on the valve head upper surface of the starting valve 24, and the spring 40 is fixed at its upper end side by a spring receiving nut 42 screwed into the inner hole 18. ing. The nut 42 has a through hole for water passage. The piston main valve 16 is provided with a small hole 44 that communicates the upper and lower chambers A and C with each other. Reference numeral 46 indicates a strainer.

The cover cap 30 is provided with a water drainage port 48, and the water drainage port 48 is communicated with an electrically driven control valve (not shown in FIG. 3) such as a solenoid valve or an electric valve via a water drainage pipe. .

In the flash valve having such a configuration, when the lever 26 is pushed and the start valve 24 is tilted, the water in the chamber (working chamber) B above the piston main valve 16 is made into the inner hole of the piston main valve 16.
It flows through 18 into the chamber C on the outflow side of the partition wall 20.
As a result, the water pressure balance between the chamber A and the working chamber B on the upstream side of the piston main valve 16 is broken, and the piston main valve 16 is pushed up by the water supply pressure in the chamber A to open and the water supply from the inlet 12 is supplied. Flows through chambers A and C towards the toilet bowl. On the other hand, during this outflow, water gradually flows into the working chamber B through the small hole 44, and the piston main valve 16 is gradually pushed down by the water pressure to eventually close the flow of washing water.

When the switch is operated to open the electrically operated control valve instead of pushing the lever 26, the water in the working chamber B is drained through the drain pipe and the piston main valve 16 is lifted. , Water flow starts. After that, when the control valve is closed, water gradually flows into the working chamber B through the small hole 44,
Eventually, the piston main valve 16 closes.

[Problems to be solved by the invention] In a Western-style toilet that does not have a low tank but is supplied with cleaning water via a flush valve, a water supply pipe dedicated to the warm water cleaning device is installed to supply water to the warm water cleaning device. Therefore, the installation of a hot water cleaning device was a major task.

[Means for Solving the Problems] A toilet bowl with a hot water cleaning device of the present invention is a toilet bowl equipped with a nozzle for ejecting hot water toward a human buttocks and a tank for supplying hot water to the nozzle, and a toilet bowl. Remote control flush valve provided on the water supply pipe for supplying wash water to
In a toilet bowl with a hot water washing device having a drainage pipe for draining water from the operation chamber for opening the flush valve and an electrically driven control valve provided in the drainage pipe, the operation switch of the control valve is washed with hot water. It is characterized in that the water intake pipe is branched from a water supply passage upstream of the flush valve and provided with an operation switch of the apparatus, and water can be supplied to the tank by the water intake pipe.

[Operation] According to the toilet bowl with the hot water washing device of the present invention, since the water for the hot water washing device can be dispensed from the water supply passage, the hot water washing device can be installed in the Western-style toilet provided with flush water by the flush valve. When it is installed, the pipeline installation work of the water supply pipe for the hot water washing device becomes extremely easy.

Further, since the operation switch of the electrically driven control valve for operating the flush valve and the operation switch of the hot water cleaning device are arranged together, various electric parts can be centrally arranged.

[Embodiment] FIG. 1 is a perspective view of a Western-style toilet having a hot water cleaning device according to an embodiment, and FIG. 2 is a water flow system diagram.

This Western-style toilet is provided with a first water supply pipe 52, a water stopcock 54, a second water supply pipe 56, a remote control flush valve 58 having the structure shown in FIG. 3, a vacuum breaker 60, and a third water supply pipe 62. Wash water is supplied. The water stop 54 is provided with a water intake 54a.

A toilet seat box 64 is installed in the Western-style toilet 50, and a hot water tank 66, a washing valve 68, a hot water washing nozzle 70, a control valve 72 for controlling the flush valve 58, and the like are provided in the toilet seat box 64. Although not shown, a warm air blowing device for drying the buttocks is also installed.

The toilet seat box 64 is provided with an inlet 74 for introducing tap water into the hot water tank 66 and an inlet 76 for the control valve 72.
