A foam supply device 40 is provided in the upper portion of the raw tank 16.
Is installed. The foam supply device 40 includes a soap solution tank 42, a mixer 44 for mixing soap solution and tap water,
It is mainly composed of a foaming device 46 for foaming a mixed liquid of water and soap liquid.

A water pipe 48 branched from the ball tap 32 is connected to the mixer 44 via a first valve 50. This mixer 44, as shown in FIG.
It is composed of a Venturi pipe, and a soap liquid supply pipe 52 is connected to the negative pressure generating portion 44a of the mixer 44.

The foaming device 46 applies a mixture of water and soap liquid to the mesh 56 together with the air from the air intake pipe 54,
It is configured to be mixed and foamed. The foamed foam is supplied to the toilet bowl 12 via the tube 58. The tube 58 is routed between the raw tank 16 and the tank cover 26.

From the tap water pipe 48, the foam supply device 3
No. 0 water-washing pipe 60 is branched, and the pipe 60 is connected to the downstream side of the mesh 56 of the foaming machine 46 via the second valve 62. The second valve 62 is controlled by the controller 64 together with the first valve 50. A control signal is input to the controller 64 from a foam supply switch 66 (which may be a seating switch, a remote controller, a human body sensor, or the like) provided at an appropriate location such as the tank cover 26 or the wall surface of the toilet room. To be done.

In the Western-style toilet 10 thus constructed, when the foam supply switch 66 is operated, the first valve 50 is opened by a signal from the controller 64, and the water from the pipe 48 flows into the mixer 44. . When this water passes through the negative pressure generating portion 44a of the mixer 48, the generated negative pressure causes the soap solution in the soap solution tank 42 to be sucked in through the soap solution supply pipe 52 to mix the water / soap solution mixture. Device 44 to foamer 46
Is supplied to. Then, the air taken in from the air intake pipe 54 and the mixed liquid hit the mesh 56, and bubbles are generated. This foam is supplied to the toilet bowl 12 via the tube 58.

When the hand is released from the foam supply switch 66, the first
The valve 50 is closed, the foam supply is stopped, and the second
The valve 62 opens for a predetermined time. As a result, tap water is introduced into the foaming device 46 from the pipe 60, and the insides of the foaming device 46 and the tube 58 are washed. This prevents the soap content from remaining in the foamer 46 and the tube 58 and solidifying.

When the foam supply switch 66 is pressed, the first
The valve 50 may be opened for a predetermined time, a predetermined amount of foam may be automatically supplied to the toilet bowl 12, and then the second valve 62 may be opened for a predetermined time.

In the above embodiment, the air intake pipe 54 is inserted into the upper portion of the overflow pipe 36. However, by doing so, even if the mesh 56 is blocked, the mixture of water and soap liquid is mixed. The liquid can be discharged to the overflow pipe 36 via the air intake pipe 54. In this case, since the mixed liquid of water and water soap solution does not flow into the low tank 16, it is possible to prevent the packing and the like in the low tank 16 from coming into contact with the soap solution and deteriorating.

In the above embodiment, the foam is supplied to the toilet bowl 12 via the tube 58, but as shown in FIG. 6, the foam from the foaming machine 46A is passed through the overflow pipe 36 and the water supply passage 20. Alternatively, it may be supplied to the toilet bowl 12.
