The present invention relates to a foot valve-type water-saving shower with a thermostatic control, in particular, the water discharge and the step number by the step of stepping on the foot valve installed on the floor of the shower room without using your hands to turn on or off the water during the shower The foot valve is provided with a hot / cold water mixing valve that automatically controls the amount of hot water mixed with cold water according to a preset discharge temperature so that water of a temperature suitable for showering is discharged from the shower nozzle.

As a prior art for the thermostatic shower associated with the present invention is known as 'water temperature automatic shower' of Utility Model Publication No. 84-2764, which is a valve of the hot water pipe and the cold water pipe connected to the lower end of the gas The opening and closing period of the conical screw rod to open and close the valve is inserted into the toilet room, and several hot water inflow holes are drilled on the upper surface of the cold water chamber guided into the hot water pipe and can be elevated to the inner wall of the cold water chamber. In the upper part of the valve tube on which the water hole is driven, the lower part of the support rod in which the plurality of bimetallic holes are inserted and the upper part of the spring installed in the cold water chamber are attached to the fixing device so that the bottom of the lower side of the bimetal can be elevated and adjusted by the pinion. Pipes are connected to each other so that the lower and upper parts of the switching valves, which are installed in contact with the resident, and which have a flat fan-shaped hole in the upper part of the body, can be rotated. This was more convenient than the method of controlling the temperature of the mixed water by controlling the two hot and cold water valves respectively, but the operation of opening and closing the hot and cold water valves had to be done by hand, and inside the hot and cold water mixing pipe. Due to the complex structure of the present invention, there was a practical difficulty in actual production and use, and the water-saving function to be achieved in the present invention had a disadvantage not found.

In addition, the conventional technology for a foot valve type showerhead according to the present invention is known as a 'shower with a multi-pedal' of Utility Model Publication No. 96-2623, which is connected to the shower head by a water supply control valve connected to the water supply pipe In the shower to be supplied with water, the inlet pipe and the outlet pipe is formed to extend, and the inlet and outlet connected to the inlet and outlet provided with a multi-pedal unit, and the multi-pedal unit is provided with a footrest, the multi-pedal unit The body, the cover nut and the underside form an outer shape, and seven foot pedals having the same shape are spring-tipped on the support, and the foot pedal is configured to block the channel with an O-ring and packing, so that at least one foot Even when the pedal is pressed, water is supplied from the water supply room to the drainage room and water is sprayed to the shower head through the outlet port and the outlet pipe. If you step on one of the multi-pedal with your hands without showering, you can get water out of the shower head, but the water-saving function of the multi-pedal is too big and complicated. There was installation trouble to connect the hot / cold water mixer to the multipedal to adjust the temperature suitable for showering, and also had to use the hands, and to suddenly open / close the foot pedal when stepping or releasing the foot pedal. There was a lung where water hammering occurred.

The present invention has been made in view of the above-mentioned conventional problems, the object of the present invention is to be showered all the time without having to use your hand at all when showering, and when soaping or other operations in the shower room is automatic As water is not discharged, it is possible to achieve maximum water-saving function and energy saving, and to provide a shower device in which water hammering does not occur when water is discharged and water is shortened.

In order to achieve this purpose, the water is discharged from the shower nozzle and the water is discharged from the shower nozzle by stepping on or releasing the foot valve installed at an appropriate position on the floor of the shower room without using hands to turn or lock the water. The foot valve is equipped with a hot / cold water mixing valve that automatically controls the amount of hot water mixed with cold water according to a preset outlet temperature so that water of a suitable temperature for showering is discharged. It provides a foot valve-type water-saving shower with a thermostatically controlled double valve structure that does not generate water hammering.
