る。In the embodiment of the present invention, as shown in FIGS. 1 and 2 (a) and (b), the flow rate control valve A is a temperature control valve B and a water tap C.
Along with the mounting holes 2, 2a, 2b formed in the top plate 1 such as a wash basin or sink via nuts 3, 3a, 3b, the flow rate control valve A is upstream from the valve seat opening 4. The temperature control valve B and the solenoid valve D on the downstream side are connected to each other through a flow path 5, and a cylinder 6 is connected and arranged in the middle of the flow path 5 with a valve seat opening 4a as a boundary. 6
A switching valve 9 having a communication port 8 and a communication port 8a capable of communicating the valve seat port 4a with an opening 7 described later is interposed between the valve seat port 4a and the opening 7 and a spring 11 is provided between the switching valve 9 and the blind lid 10. As well as ammo
The inner end of a rod 12 penetrating the blind lid 10 from the outside and the bottom surface of the switching valve 9 are integrally coupled, and the outer end of the rod 12 is connected to one end of a foot-operated petal 13. The bypass pipe 14 has one end connected to the opening 7 of the cylinder 6,
The emergency hot water supply means E is constructed such that the other end communicates with a pipe 15 described later through a pipe joint 16. The temperature control valve B
Are provided with water valve seats 17 and hot water valve seats 18 on the upper and lower sides in the vertical direction, and communicate with a water supply source and a hot water supply source, respectively. In the water valve section 20
The valve bodies 22 each having the hot water valve portion 21 provided at the bottom are integrally attached. The flow rate control valve A communicates with the valve seat 4 and the water valve seat 17 and the hot water valve seat 18 of the temperature control valve B, respectively, and the valve seat 23 has a valve body 23 of a valve shaft 19a.
The flow rate can be adjusted freely. The valve seat 4b of the solenoid valve D communicates with the flow path 5 and the valve seats 4 and 4a on the upstream side and also communicates with the pipe 15 via the check valve seat 24 on the downstream side. The extension end communicates with the water tap C, and the head 26 at the tip of the water discharge pipe 25 of the water tap C is connected to the solenoid valve D through an electric wiring F in response to a hot water discharge port 27 and a hand or other object. 28 to automatically open and close
Are provided respectively. FIG. 4 shows another embodiment of the emergency hot water supply means E. This emergency hot water supply means E ′ has another valve seat opening 4c facing the downstream side of the valve seat opening 4a provided in the cylinder 6a. And a switching valve 9a is elastically corresponded to the valve seat opening 4c by a spring 11, and the switching valve 9a is connected to the rod 12a.
Is attached to the lower end of the rod 12, and the petal 13a supported by the sleeper 29 is connected to form the pallet 30.
When the pedal is stepped on the outside of the rod 12, the rod 12 rises via the petal 13a, and the switching valve 9a integrated with the rod 12 is raised against the accumulated force of the spring 11 to open the valve seat opening 4c. It was done. It should be noted that the cylinders 6 and 6a may be separately provided and may be attached to existing ones without limitation. Now, when an object such as a hand or an article requiring cleaning is inserted into the space below the discharge port 27 shown in FIG. 1, the sensor 28 senses the presence of this object, and the sensor 28 causes the solenoid valve D to operate. Energize to open the valve seat opening 4b. In this case, if the flow rate control valve A is in the open state, the fluid whose temperature has been previously adjusted to an appropriate temperature by the temperature control valve B is the flow path 5a, the valve seat opening 4, the flow path 5, the valve seat opening 4b, and the check valve. It reaches the water tap C through the valve seat port 24 and the pipe 15, and is normally supplied from the discharge port 27 through the water tap C and the water discharge pipe 25. The valve D immediately stops the exciting action and closes the valve seat opening 4b. The solenoid valve D closes the valve seat 4b to stop the discharge of the hot water, so that the user has a petal 13
When the operation of stepping on is performed, the switching valve 9 connected to the petal 13 via the rod 12 resists the elasticity of the spring 11 to move the inside of the cylinder 6 from the position shown in FIG. Displace to position. Due to the displacement of the switching valve 9, the switching valve 9
Since the communication port 8a of the flow path 5 communicates with the opening 7 of the bypass pipe 14, the fluid in the flow path 5 passes through the valve seat port 4a, the communication ports 8 and 8a, the opening 7 and the bypass pipe 14, and then to the pipe 15. When it reaches, hot water is supplied from the discharge port 27 as described above. Petal 13 when finished
When the foot is released from, the switching valve 9 is restored to the position shown in FIG. 2 (a) by the elastic return of the spring 11, and the hot water supply is stopped. Also, in the case of another embodiment, the operation is performed according to the above.

があっても機能的に何等の支障もない。(1) A switching valve, which communicates via a valve seat opening and has a communication opening, is elastically interposed in the middle of the flow path connecting the flow rate control valve and the solenoid valve, and this switching valve is connected to the petal via a rod. Therefore, when the solenoid valve is closed due to a sudden power failure, not only can you freely discharge the hot water by simply stepping on the petal, but you can accidentally step on the petal or There is no problem in terms of functionality even if there is something that is misled.
