DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for introducing air for bubbles in a bath apparatus.

[0002]

2. Description of the Related Art Conventionally, when a bath apparatus is used for hot water supply, there is an apparatus shown in FIG. In FIG. 2, a water supply port 2 of a 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 tap 5 to a mixing tap 7 to a bathtub 6. The water side of the mixing tap 7 is connected to a water supply source.

In the above configuration, hot water is stored in the hot water tank 1 by the heater 4 using midnight power. When filling the bathtub, the mixing tap 7 is adjusted to supply hot water at an appropriate temperature. When the temperature of the hot water is restored to a suitable temperature after the use of the bath water, the mixing tap 7 is set at a high temperature and hot water in the hot water storage tank 1 is poured into the bath 6 to raise the temperature of the hot water in the bath. Also,
In the case of a conventional bath apparatus, there was no hot-water storage type having a bubble bath function. In addition, although there is a type of instantaneous water heater (gas water heater) to which a bubble function is added, air for the bubble is introduced from outside the main body of the bath apparatus.

[0004]

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

The present invention solves the above-mentioned problems. An air inlet for air bubbles is provided in a space above a hot water storage tank, and air for air bubbles is introduced into the bath tub from the upper space when an air bubble switch of an operation unit is operated. It is another object of the present invention to provide a bath apparatus having a configuration in which a flow of air is generated in an upper space to suppress a rise in temperature.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a reheating unit for connecting a bath to a bath to heat and circulate bath water in a space between an upper part of a hot water storage tank and a top plate at the top. A reheating circuit consisting of a heater and a pump,
A pouring circuit connected to the reheating circuit through a hot water mixing valve and a pouring on / off valve for mixing tap water and water from the hot water tank, a temperature detector and a water level detector provided in the reheating circuit, An air intake valve connected to the bathtub with an air connection hose is provided with a solenoid valve for air intake and an air intake port. By operating a bubble switch of an operation unit provided in the bathtub, air for bubble generation is taken in from the space. To be configured.

[0007]

According to the present invention, the hot water and the hot water in the hot water tank are adjusted to an appropriate temperature by the hot 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 tub water is re-fired by the re-heating heater. Then, the reheating is automatically stopped at the set temperature. Further, when the temperature is set to a high temperature, the temperature of the bath water is raised by 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 by the bath water circulation. This suppresses a temperature rise in the upper space.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a bath apparatus according to one embodiment of the present invention. In the figure, hot water from a hot water outlet 5 of a hot water storage tank 1 and water supply from a pressure reducing valve 3 are connected to a hot / 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 outgoing 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 connected from an outlet of the hot / cold mixing valve 8 to a reheating circuit between the two-way valve 12 and the flow detector 17 via the pouring / opening valve 18 and the check valve 19 is formed. The pouring circuit is provided with a vacuum break valve 20 to cut off the water supply source and the bathtub 6. In addition, connection adapter 9 of bathtub 6
, An air connection hose 21 is connected to an air connection port 22, and an air introduction path for a bubble bath is formed from the air connection port 22 to a solenoid valve 24 for air and an air intake port 25 via another air hose 23. The hot water mixing valve 8 and the pump 1
1, a two-way valve 12, a pouring on / off valve 18, and a solenoid valve 26 for air are respectively provided with a hot water mixing valve driving device 26 and a pump driving device 2
7. A two-way valve driving device 28, a pouring opening / closing valve driving device 29, and an air solenoid valve driving device 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. Is controlled by the heater 31. The above is configured in the space 33 between the upper part of the hot water tank 1 and the top plate 32, and automatic hot water supply at the water level and hot water temperature set by the bathroom operation part 34 and the bathroom outside operation part 35 provided in the bathroom and outside the bathroom is provided. The controller 31 controls each of the above-described driving devices and detectors in response to a setting signal of the bathroom operation unit 34 and the bathroom outside operation unit 35 which can be selected.

In the above configuration, at the time of automatic hot water supply, the controller 31 drives the two-way valve driving device 28 to close the two-way valve 12 by pressing the tap switch 36 of the bathroom operation unit 34 or the operation unit 35 outside the bathroom. Then, with the pump 11 stopped, the pouring / opening / closing valve driving device 29 is driven to open the pouring / opening / closing valve 18. The mixed water adjusted to an appropriate temperature by the hot water mixing valve 8 by driving the hot water mixing valve driving device 26 is poured into the bathtub 6 from the connection adapter 9 via the outgoing pipe 14 of the reheating circuit. When the filling is completed to the water level set in advance by the operation unit, the controller 31 drives the pouring on / off valve driving device 29 to close the pouring on / off valve 18.

At the time when the filling is completed, the bathroom operation unit 34
When the air bubble switch 37 is pressed, the controller 31 drives the pump driving device 27 to operate the pump 11, and recirculates the bathtub water in the heating circuit at the set flow rate. At the same time as the operation, the air solenoid valve driving device 30 is driven so that the
4 is opened, and from the air intake port 25 for bubbles in the space above the hot water tank 1 through the air hose 23 via the air solenoid valve 24, from the air connection port 22 to the connection adapter 9 of the bathtub 6 by the air connection hose 21. An air introduction path for the bubble bath is formed, and air is drawn from the air intake port 25 by an ejector effect due to the circulation of the reheating circuit.
As a result, the heated air in the space above the hot water tank 1 is sucked, and low-temperature air outside the bath apparatus 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 air bubbles are generated in the bathtub, by operating the air bubble switch, air is taken in from the air intake in the bath apparatus, so that a flow is created that draws external air into the hot water tank upper space,
The reliability can be improved because the temperature rise due to the heat radiation specific to the bath apparatus and the self-heating of the components in the upper space is suppressed. (2) Further, since air for bubbles is drawn from the heated upper space, air is used, so that the temperature of hot water in the bath tub is prevented from lowering due to the bubbles, and there is also an energy saving effect.
