Description

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 device.

[0002]

2. Description of the Related Art Conventionally, there is a device as shown in FIG. 3 when supplying hot water to a bath with a bath device. In FIG. 3, 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 a hot water outlet 5 to a bath 6
To the mixing tap 7 to the. 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 proper 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 6. For this reason, there has been an inconvenience that the high-temperature hot water accompanying the decrease in the hot water temperature of the bathtub 6 must be manually performed each time, and the hot water is restrained until it becomes warm. In addition, in the case of the instantaneous bath device, the circulating water in the reheating circuit was rapidly heated by the heat exchanger for reheating, so simultaneous pouring with the forward and return pipes was not possible.

[0004]

In such a conventional bath device, the high temperature hot water accompanying the decrease in the hot water temperature of the bathtub 6 must be manually performed each time, and it is inconvenient that the hot water is restrained until it reaches an appropriate temperature. There were various settings for the high temperature. In the case of a momentary bath device, the circulating water in the reheating circuit is rapidly heated by the heat exchanger for reheating and discharged from the circulating piping to the bathtub, so the flow velocity is too fast and hot water is hot. There was a risk of contact with the human body.

The present invention is to solve the above-mentioned problems. When the bath water is heated, the high temperature hot water switch is operated to control the hot water to flow to both the outgoing pipe and the return pipe,
An object of the present invention is to provide a bath device that reduces the flow rate of hot water discharged into a bathtub as compared with the case of passing hot water only through an outgoing pipe and prevents hot water 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 the bath water, and hot water discharged from a hot water storage tank. A pouring circuit connected to the reheating circuit via a hot and cold water mixing valve and a pouring on / off valve for mixing water and water, and a temperature detector for detecting the hot water temperature provided in the reheating circuit and the water level in the bathtub are detected. 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 a forward pipe and a return pipe connecting the reheating circuit of the main body and the bath. A bathroom operation unit and a plurality of hot water discharge switches of the operation unit are provided, and the hot water discharge switch has a high-temperature hot water switch for controlling hot water to flow through both the outgoing pipe and the return pipe.

[0007]

According to the present invention, with the above-described structure, when the bath water is heated, the hot water is passed through both the forward pipe and the return pipe, and the flow velocity of the hot water discharged to the forward bath is weakened as compared with the high temperature hot water of the forward pipe only. The hot water does not come into direct contact with the human body.

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. From the bath connection port 9 of the bathtub 6, the return pipe 10, the pump 11, and the two-way valve 1
2, the reheating heater 13 and the outgoing pipe 14 constitute a reheating circuit that reaches 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 on-off valve 18 and a check valve 19. A vacuum breaking valve 20 is provided in the pouring circuit to separate the water supply source from the bath 6.
The hot water mixing valve 8, the pump 11, the two-way valve 12, the pouring on-off valve 18, and the electromagnetic valve 26 for the air are respectively a hot water mixing valve driving device 26, a pump driving device 27, a two-way valve driving device 28,
It is equipped with a pouring on-off valve driving device 29 and an air solenoid valve driving device 30, and is provided with a reheating heater 13, a 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 stored in the main body 32. You can select the water level set by the bathroom operation part 33 and the outside bathroom operation part 34 provided inside and outside the bathroom, automatic hot water supply at hot water temperature, bubbles, and high-temperature hot water. The controller 31 controls each of the above driving devices.

In the above structure, when the hot water supply switch 35 of the bathroom operation unit 33 or the bathroom operation unit 34 is pressed during automatic hot water supply, the controller 31 drives the two-way valve drive 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 mixing valve 8 adjusts the hot water to an appropriate temperature.
After that, it is poured into the bathtub 6 from the bath connection port 9. 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 tapping hot water, as shown in the control flow chart of the embodiment of the present invention in FIG.
By operating the high-temperature hot water switch 36, the controller 31 drives the two-way valve drive device 28 to open the two-way valve 12, and opens the circuit in both the outflow pipe 14 and the return pipe 10.
While the pump 11 is stopped, the pouring / opening valve driving device 29 is driven to open the pouring / opening / closing valve 18, and the hot / water mixing valve driving device 2
The mixed hot water which is driven by 6 and adjusted to a high temperature (for example, about 60 ° C.) by the hot and cold water mixing valve 8 is 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.
After that, it is poured into the bathtub 6 from the bath connection port 9.

[0011]

As is apparent from the above embodiments, according to the present invention, hot water can be discharged to the bathtub through both the outgoing pipe and the return pipe by operating the high temperature hot water switch. Compared with the case of doing so, the discharge flow velocity in the bathtub is weakened, and the risk of direct contact with high-temperature hot water against the human body is reduced.
