An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, a shower head for discharging hot water is composed of a hand shower head 9 and a fixed shower head 10, and the hand shower head 9 is a closed path through which hot water is sent by a shower hose 11.
(Hereinafter referred to as pipeline) , and the fixed shower head is connected to a closed path (hereinafter referred to as pipeline) through which hot and cold water is sent.
13 ) . Further, on-line valves 12 and 13 are provided with on-off valves (hereinafter referred to as motor-operated valves) 14 and 15 for opening and closing and varying the flow rate. The water heater 16 includes a burner 17 and a heat exchanger 18, a gas proportional valve 19 for variably controlling a gas amount, a hot water temperature sensor 20 for detecting tap water temperature, and a water amount sensor 2 for detecting water flow rate.
1 and the like are incorporated. Further, hot water from the water heater 16 and a water- tight path (hereinafter referred to as a water pipe) . A hot water sealing path (hereinafter referred to as a hot water pipe) at an outlet of the heat exchanger 18 of the hot water supply 16
24 ) and the water conduit 22 are connected. The hot and cold water mixing unit 23 is provided with check valves 25 and 26 at hot water side and water side inlets, respectively, and an electric mixing valve 27 for variably controlling and opening and closing the mixing ratio and amount of hot water through the check valves 25 and 26. , 28, the temperature of the mixed hot and cold water is detected by a hot water temperature sensor 29, which is a temperature detector, and the amount of hot water is detected by a hot water flow sensor 30.
The hot water temperature and flow rate are controlled while feeding back to 7, 28. Further, downstream of the electric mixing valves 27 and 28, an air pump 32 serving as a gas supply means is connected to an electric valve 33 in a closed path (hereinafter referred to as a pipe) 31 for sending hot water to the hand shower head 9 and the fixed shower head 10. , Heater 3
4. It is connected via a check valve 35. Heater 3
The heating section 36 is constituted by an electric heater or a heat exchanger capable of circulating the hot water of the water heater 16. Also, between the hot water side inlet of the hot water mixing unit 23 and the water side inlet of the water heater 16,
The circulation path 39 is connected through a circulation pump 37 and a check valve 38 to form a circulation path 39.

In the above configuration, at the time of completion of the discharge of hot water such as a shower, the motor-operated mixing valve 2 which is also an on-off valve provided in the conduit 31 for sending hot water to the jet nozzles such as the shower heads 9 to 10.
7 and 28 are closed, and pressurized air is supplied to the downstream of the electric mixing valves 27 and 28 by an air pump 32 which is a gas supply means for mixing gas such as air. Hot water in the downstream shower hose 11 is pushed out of the shower heads 9 to 10 by pressurized air. That is, in the pipe 31 for feeding hot and cold water, the hot and cold water after the gas supply section such as pressurized air is discharged, and the hot water and the like in the pipes 31, 12, 13 and the shower hose 11
The hot and cold water is replaced with a gas such as air. Therefore, when hot water is discharged to the human body, such as at the start of use of a shower, since the inside of the shower hose 11 is a gas such as air, the hot water upstream of the electric mixing valves 27 and 28 serving as the open / close valves quickly flows into the shower head 9. It acts so as to be able to be discharged from the ejection nozzles such as 10 to 10 so that it is possible to prevent the water in the shower hose 11 from being erroneously bathed and to cool the liver cold.

When the supply pressure of the hot water supplied from the upstream of the electric mixing valves 27 and 28 is low, the force of the jets such as the shower jetted from the jet nozzles such as the shower heads 9 to 10 is weakened, and the user can use the jet head. Although the user feels unsatisfactory and cannot easily obtain comfort and satisfaction, the present invention provides the above-described configuration in which the pressurized air of the air pump 32 serving as a gas supply unit for air or the like is supplied while the electric mixing valve is opened. When the hot and cold water is supplied to the conduit 31, the pressurized air mixed with the hot and cold water is discharged from the jet nozzles such as the shower heads 9 and 10, and the hot and cold water acts on the body with the same force. In spite of the small amount of hot water flow, the hot water is blown to the body by air pressure, and as a shower feeling, as if the shower flow increased, the high pressure shower It is possible to bring about a specific effect, such as can be obtained.

Further, according to the embodiment of the present invention, when the discharge of hot water such as a shower is completed, the shower head 9 is provided.
By closing the electric mixing valves 27 and 28 which are also on-off valves provided in the conduit 31 for sending hot and cold water to the jet nozzle, the shower hose 11 and the conduit are supplied by supplying gas such as pressurized air by the air pump 32. The hot and cold water in the inside 12 is pushed out from the ejection nozzles such as the shower head 9 by the gas such as the pressurized air, and then the gas such as the pressurized air can be ejected from the ejection nozzles such as the shower head 9. It is possible to bring about a specific effect that cooling can be performed by air of a gas such as pressurized air, or water droplets on a wet body can be blown off by a gas such as air ejected from the shower head 9 to promote drying. In this case, if the heating unit 36 is operated, warm air can be obtained, and not only drying but also heating can be performed.

In recent years, the so-called bubble bath, which is capable of taking a bath while blowing air bubbles into a bathtub, has been gaining in popularity.
By closing the motor-operated on-off valves 27 and 28 provided in the pipe line 31 for feeding hot and cold water to the equalizing nozzle and supplying gas such as pressurized air by the air pump 32, the compressed air from the nozzle such as the shower head 9 is compressed. Etc. can be ejected. Therefore, by putting the jet nozzle such as the shower head 9 in hot water of a bathtub (not shown), it is possible to enjoy so-called bubble bathing while jetting air bubbles into the bathtub.

In the above-described embodiment, the case where the instantaneous gas water heater is used has been described. However, the same effect can be obtained by using an electric hot water heater. In this embodiment, a shower used in a bathroom or the like has been described. However, it is needless to say that the present invention is not limited to this as long as the object of the present invention is achieved.
