In FIG. 2, the water supply port 2 of the hot water storage tank 1 is connected to a water supply source via a pressure reducing valve 3. A heater 4 is provided in the hot water storage tank 1 and is guided from a hot water outlet 5 to a mixing tap 7 into a bath 6. The water side of the mixing tap 7 is connected to a water supply source.

In the above structure, hot water is stored in the hot water storage tank 1 by the heater 4 using the midnight power. When filling the bathtub with hot water, the mixing tap 7 is adjusted to supply hot water of an appropriate temperature. After the bath water has been used, when the hot water temperature is restored to a suitable temperature, the mixing tap 7 is set to a high temperature and the hot water in the hot water storage tank 1 is poured into the bathtub 6 to raise the hot water temperature in the bathtub. Also,
In the case of the conventional bath equipment, there was no storage type with a bubble bath function. There is also a model with a bubble function added to the instantaneous hot water heater (gas water heater), but the air for the bubbles was introduced from outside the body of the bath device.

[0004]

In such a conventional bath device, there is no bubble bath function in the case of the hot water storage type, or in the case of the bath device with the instantaneous type bubble bath function, the air for the bubble bath is supplied from the outside of the main body. Because of the introduction, unlike the hot-water storage type bath apparatus of the present invention, it was not possible to prevent the temperature of the atmosphere in the upper space from rising due to radiative convection due to hot water from the hot-water storage tank and self-heating of the component parts.

The present invention is to solve the above-mentioned problems. An air inlet for bubbles is provided in the space above the hot water tank, and air for bubbles is introduced from the upper space into the bath when the bubble switch of the operating portion is operated. An object of the present invention is to provide a bath device configured to suppress the temperature rise by generating an air flow in the upper space.

[0006]

In order to achieve the above object, the present invention is a reheating apparatus for heating and circulating bath water connected to a bath in a space between the upper part of the hot water tank and the top plate of the bath apparatus. A reheating circuit consisting of a heater and a pump,
A pouring circuit connected to the reheating circuit via a hot water mixing valve and a pouring opening / closing valve for mixing the hot water and hot water of the hot water storage tank, and a temperature detector and a water level detector provided in the reheating circuit. An air solenoid valve for air intake connected to the bathtub with an air connection hose and an air intake port are provided, and the air bubble generation operation is performed from the space by operating a bubble switch of an operation unit provided in the bathtub. To configure.

[0007]

According to the present invention, with the above construction, the hot and cold water of the hot water storage tank is adjusted to an appropriate temperature by the hot and cold water mixing valve, the hot water is poured into the bath, and the filling is automatically stopped at the set water level. In addition, the reheating heater reheats the bath water. Then, the reheating is automatically stopped at the set temperature. When the temperature is set to a higher temperature, the temperature of the bath water is raised with hot water. Then, by operating the bubble switch of the operation unit, the bath water is circulated by the operation of the pump, the solenoid valve for air is opened, and the air for bubbles is introduced from the air inlet in the upper space by the ejector effect of the bath water circulation. , It suppresses the temperature rise in the upper space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a bath device according to an embodiment of the present invention. In the figure, hot water from the hot water outlet 5 of the hot water tank 1 and water supply from the pressure reducing valve 3 are connected to the hot and cold water mixing valve 8. A reheating circuit from the connection adapter 9 of the bathtub 6 to the bathtub 6 is constituted by the return pipe 10, the pump 11, the two-way valve 12, the reheating heater 13 and the outflow pipe 14. The reheating circuit is provided with a temperature detector 15, a water level detector 16 and a flow detector 17. A pouring circuit is formed which is connected to the reheating circuit between the two-way valve 12 and the flow detector 17 via the pouring opening / closing valve 18 and the check valve 19 from the outlet of the hot / water mixing valve 8. A vacuum breaking valve 20 is provided in the pouring circuit to separate the water supply source from the bath 6. Also, the connection adapter 9 for the bathtub 6
The air connection hose 21 is connected to the air connection port 22, and an air introduction path for the bubble bath is formed from the air connection port 22 to the air solenoid valve 24 and the air intake port 25 via another air hose 23. Hot water mixing valve 8 and pump 1
The hot and cold water mixing valve drive device 26 and the pump drive device 2 are provided for the one-way valve 12, the pouring pouring on-off valve 18, and the solenoid valve 26 for air, respectively.
7, a two-way valve drive 28, a pouring on-off valve drive 29, and an electromagnetic solenoid valve drive 30 are provided, and are controlled together with the reheating heater 13, the temperature detector 15, the water level detector 16, and the flow detector 17. It is controlled by the device 31. The above is configured in the space 33 between the upper part of the hot water storage tank 1 and the top plate 32, and automatic hot water supply at the water level and the hot water temperature set by the bathroom operation unit 34 and the bathroom operation unit 35 provided inside and outside the bathroom It can be selected, and the controller 31 controls the above-mentioned drive devices and detectors in response to the signals of the settings of the bathroom operation unit 34 and the operation unit outside the bathroom 35.

In the above structure, when the hot water is supplied automatically, the hot water outlet switch 36 of the bathroom operating portion 34 or the outside bathroom operating portion 35 is pushed to cause the controller 31 to drive the two-way valve driving device 28 to close the two-way valve 12. While the pump 11 is stopped, the pouring / opening valve driving device 29 is driven to open the pouring / opening valve 18. The hot water mixing valve drive device 26 is driven, and the hot water mixed by the hot water mixing valve 8 is adjusted to an appropriate temperature, and the hot water is poured into the bathtub 6 from the connection adapter 9 through the forward pipe 14 of the reheating circuit. When the filling of water to the water level set in advance by the operation unit is completed, the controller 31 drives the pouring opening / closing valve driving device 29 to close the pouring opening / closing valve 18.

When the water filling is completed, the bathroom operation unit 34
When the bubble switch 37 is pressed, the controller 31 drives the pump driving device 27 to operate the pump 11, and circulates the bath water at the set flow rate in the reheating circuit. Simultaneously with the operation, the air solenoid valve drive device 30 is driven to drive the air solenoid valve 2

An air introduction path for the bubble bath is formed, and the air is drawn from the air intake port 25 by the ejector effect due to the circulation of the reheating circuit.
As a result, the heated air in the space above the hot water storage tank 1 is sucked in, and low-temperature air outside the bath device enters the upper space, so that the temperature rise in the upper space is suppressed.

[0011]

As is apparent from the above embodiments, the following effects can be obtained according to the present invention. (1) When bubbles are generated in the bathtub, air is taken in from the air intake port in the bath device by operating the bubble switch, so that a flow that draws external air into the hot water tank upper space is created,
Reliability is improved because the temperature rise due to the heat radiation peculiar to the bath device and the self-heating of the components in the upper space is suppressed. (2) Further, since the air for the bubbles uses the drawn air from the warmed upper space, it is possible to prevent the decrease in the temperature of the hot water in the bathtub due to the bubbles, and thus there is an energy saving effect.
