DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for hot water in a bath apparatus.

[0002]

2. Description of the Related Art Conventionally, there is an apparatus as shown in FIG. 3 for supplying hot water to a bath with a bath apparatus. In FIG. 3, 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 a hot water outlet 5 and a bathtub 6 are provided.
To the mixing tap 7. 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 temperature of 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 bath 6 to raise the temperature of the hot water in the bath 6. For this reason, there has been an inconvenience that the hot water must be manually supplied each time the temperature of the hot water in the bathtub 6 decreases, and the hot water is restrained until the temperature becomes high. In addition, in the case of the instantaneous bath apparatus, since the circulating water in the reheating circuit is rapidly heated by the reheating heat exchanger, simultaneous pouring by the outflow pipe and the return pipe cannot be performed.

[0004]

In such a conventional bath apparatus, high-temperature hot water must be manually supplied each time the temperature of the bathtub 6 decreases, and the bath is constrained until the temperature reaches an appropriate level. And high temperature settings varied. In the case of instantaneous bath equipment, the circulating water in the reheating circuit is rapidly heated by the reheating heat exchanger and discharged to the bathtub from the circulating outgoing piping, so the flow velocity is too fast and the hot water is too hot. Was at risk of contact with the human body.

The present invention has been made to solve the above-mentioned problem, and controls the hot water supply switch to heat the bathtub water so that the hot water is supplied to both the outgoing pipe and the return pipe.
It is an object of the present invention to provide a bath apparatus in which the flow velocity of hot water discharged to a bathtub is reduced as compared with a case where hot water is passed only through an outgoing pipe, and high-temperature hot water is prevented from directly contacting a human body.

[0006]

In order to achieve the above object, the present invention provides a reheating circuit comprising a reheating heater for heating bath water in a bathtub and a pump for circulating bath water; A pouring circuit connected to the reheating circuit via a hot water mixing valve and a pouring on / off valve for mixing water and water; a temperature detector provided in the reheating circuit for detecting hot water temperature; and detecting a water level in a bathtub. A water level detector, a two-way valve for switching between the reheating circuit and the pouring circuit, a main body composed of a controller, and an outgoing pipe and a return pipe connecting the reheating circuit of the main body and the bathtub. A bathroom operation unit and a plurality of tap switches of the operation unit, wherein the tap switch has a high-temperature tap switch for controlling hot water to be supplied to both the outgoing pipe and the return pipe.

[0007]

According to the present invention, when the bathtub water is heated, the hot water flows into both the outgoing pipe and the return pipe when heating the bathtub water. The hot water does not come into direct contact with the human body.

[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. Return pipe 10, pump 11 and two-way valve 1 from bath connection port 9 of bathtub 6
2, a reheating heater 13 and an outgoing pipe 14 constitute a reheating circuit reaching the bathtub 6. The reheating circuit is provided with a temperature detector 15, a water level detector 16, and a flow detector 17. The outlet of the mixing valve 8 is connected to a reheating circuit between the two-way valve 12 and the flow detector 17 via a pouring / opening / closing valve 18 and a check valve 19. The pouring circuit is provided with a vacuum break valve 20 to cut off the water supply source and the bathtub 6.
The hot water mixing valve 8, the pump 11, the two-way valve 12, the pouring on / off valve 18, and the solenoid valve 26 for air are respectively provided with a hot water mixing valve driving device 26, a pump driving device 27, a two-way valve driving device 28,
A pouring on / off valve driving device 29 and an air solenoid valve driving device 30 are provided, and the reheating heater 13, the temperature detector 15,
It is controlled by the controller 31 together with the water level detector 16 and the flow detector 17. The above is contained in the main body 32. The water level, automatic hot water supply at the hot water temperature, air bubbles, and hot water supply set by the bathroom operation section 33 and the outside operation section 34 provided outside the bathroom can be selected. The controller 31 controls each of the above driving devices.

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 hot water switch 35 of the bathroom operation part 33 or the outside operation part 34. Then, the pouring on / off valve driving device 29 is driven while the pump 11 is stopped to open the pouring / on / off valve 18. The mixed hot water, which is driven to the appropriate temperature by the hot and cold water mixing valve 8 by driving the hot and cold water mixing valve driving device 26, is supplied to the outgoing piping 14 of the reheating circuit.
, And is poured into the bathtub 6 from the bath connection port 9. 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.

When hot water is discharged, as shown in the control flow chart of one embodiment of the present invention in FIG.
The controller 31 drives the two-way valve driving device 28 to open the two-way valve 12, and opens circuits in both the outgoing pipe 14 and the return pipe 10 by operating the high-temperature hot water switch 36.
With the pump 11 stopped, the pouring / opening / closing valve driving device 29 is driven to open the pouring / opening / closing valve 18, and the hot / water mixing valve driving device 2 is opened.
The mixed hot water whose temperature has been adjusted to a high temperature (for example, about 60 ° C.) by the hot / water mixing valve 8 by driving the hot water 6 is supplied to the outgoing pipe 14 from the outgoing connection port 37 and the return pipe 10 from the return connection port 38 of the reheating circuit.
, And is poured into the bathtub 6 from the bath connection port 9.

[0011]

As is apparent from the above embodiment, according to the present invention, the hot water can be discharged into the bathtub through both the outgoing pipe and the return pipe by operating the hot water tap switch. As compared with the case where the hot water is discharged, the discharge flow velocity in the bathtub is weakened, and the danger of the hot water coming into direct contact with the human body is reduced.
