DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water supply apparatus capable of supplying electrolyzed water to a bathtub.

[0002]

2. Description of the Related Art Conventionally, there is a hot water supply apparatus as shown in FIG. In FIG. 2, a hot water storage tank 1 is connected to a water supply source via a water supply port 2 and a pressure reducing valve 3. From the tap 4 in the hot water storage tank 1, it is guided to the mixing tap 5. The water side of the mixing tap 5 is connected to a water supply source.

[0003] In the above configuration, when the bathtub 6 is filled with hot water,
Hot water stored in hot water storage tank 1 is supplied as hot water at an appropriate temperature through mixing tap 5.

Conventionally, it has been said that the effect of adjusting the PH value is that when the skin is weakly acidic and the body is weakly alkaline, the body balance is good, and in fact, astringent water applied to the face in female cosmetics is acidic. It is known that However, if it is limited to the body skin, PH value adjustment restricted to a local part like the face can be performed, but there is no hot water supply device that can adjust the PH value of bathtub hot water as a means to easily meet the requirement to adjust the PH value of the entire body skin. Was. For example, when adjusting the PH value of bath water, it is necessary for the user to put the electrolytic solution into the bath tub 6 and adjust the pH value to an appropriate value while watching the pH meter 7.

[0005]

In such a conventional hot water supply apparatus, the user has to adjust the PH value himself / herself each time, and is constrained until the adjustment is completed, and it takes a long time for the adjustment. .

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a hot water supply apparatus for supplying electrolytic water having a pH value automatically adjusted to a bathtub by operating an operation unit.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a hot water mixing valve for mixing water and hot water from a water heater, a hot water shutoff valve for stopping hot water from mixing, and a hot water mixing valve. An automatic hot water supply unit comprising a hot water supply circuit composed of a temperature detector for detecting a temperature, an electrolyzed water generator for generating electrolyzed water by directly using water from a water supply source , and water supply to the electrolyzed water generator. A water supply valve to be performed, an electrolyzed water generation unit having a tank for storing the electrolyzed water, a controller for controlling the automatic hot water supply unit and the electrolyzed water generation unit, and an operation electrically connected to the controller The electrolytic water
The generation unit and the automatic hot water supply unit are
And the hot water supply circuit are connected and integrated via a supply valve, and the
As shown in the figure, the electrolytic water can be supplied into the hot water supply circuit .

[0008]

According to the present invention, the operation of the operation unit is performed by the above-described structure.
Electrolyzed water generated and stored in advance by the automatic hot water supply unit
Supply to the hot water supply circuit of the
Sometimes, electrolyzed water adjusted to a desired PH value can be supplied. Ma
Also, connect the electrolyzed water storage tank and hot water supply circuit via the supply valve
So that only electrolytic water or mixed hot water is supplied
Select the supply form of electrolyzed water, etc., and supply it to the hot water supply circuit
it can.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a hot water supply apparatus according to one embodiment of the present invention. In the figure, a water level, a hot water temperature, and a PH value are set by operating a setting unit 9 of an operation unit 8, and a water supply source 1 is
The water from 1 and the hot water from the water heater 12 are mixed to make hot water of an appropriate temperature. Temperature detector 1
The controller 15 controls the hot and cold water mixing valve 10 so that the hot water temperature becomes a preset hot water temperature in accordance with the signal from 4. Hot water that has reached an appropriate temperature is sent from the automatic hot water supply unit 19 to the bathtub 6 through the outgoing pipe 20 via the heat retaining heater 16, the pump 17, and the water level sensor 18. When the water level detected by the water level sensor 18 reaches a preset water level, the hot water supply is stopped, and the controller 15 controls the two-way valve 21 to detect the hot water temperature of the bath tub to make the reheating circuit side. The temperature of the bathtub is detected by the temperature detector 14 by circulating the bathtub hot water. If the temperature is lower than the set hot water temperature, the heater 16 is energized to increase the bathtub hot water temperature.

In order to generate electrolyzed water for supplying electrolyzed water to a hot water supply circuit, first, water from a water supply source 11 is branched from just before a hot / water mixing valve 10 and is supplied via a water supply valve 23 for water supply. Lead to 22. The water supply valve 23 controls water supply to the electrolyzed water generator 22. The electrolyzed water generated by the electrolyzed water generator 22 is stored in tanks 24 and 25 of alkaline water and acidic water, respectively. When the tanks 24 and 25 of the electrolyzed water are full, the water supply is stopped so that the water supply is stopped. Vessels 26, 27
Are installed respectively. In addition, each tank 24,
25, the drainage valves 28 and 29 allow the electrolytic water in the tanks 24 and 25 to be discharged. Tank 24,
The supply of the electrolyzed water in 25 to the reheating circuit is controlled by supply valves 30 and 31, and the electrolyzed water is supplied to the bathtub 21.

[0011]

As described above, according to the hot water supply apparatus of the present invention,
For example, the electrolytic water adjusted to the desired PH value in advance is stored in the tank.
The tank and hot water supply circuit are connected via a supply valve.
As a result, the hot water supply circuit is
Water can be supplied, when filling the bathtub or when using hot water
The desired electrolyzed water can be obtained immediately. Operation unit
Operation to supply only electrolyzed water or simultaneously with mixed water
For example, the supply form of the electrolyzed water can be freely selected.
