[0011]

The configuration of the bathroom heating apparatus according to the present invention is as follows.

A fully automatic bath water heater with a reheating mechanism capable of reheating the hot water in the bathtub by circulating the hot water in the bathtub through the heat exchanger using a circulation pump. The hot water supply pipe of the reheating mechanism is branched via a three-way valve, and this branch side is connected to the hot water inlet of the hot water mat,
A bathroom heating mechanism in which the hot water outlet of the hot water mat is connected to the downstream side of the three-way valve in the hot water outflow pipe, and a bathroom heating mechanism that simultaneously drives the circulation pump of the bath tub reheating mechanism when the bathroom heating operation switch is turned on. Switch the three-way valve to the hot water mat side to circulate the hot water in the bathtub into the hot water mat, and when the temperature of the circulating hot water is lower than the set temperature, ignite the gas burner of the bathtub reheating mechanism and heat it. The heated hot water is circulated through the hot water mat, and the temperature in the bathroom is detected by a bathroom temperature detection sensor. When the temperature reaches the set temperature, the circulation pump is stopped and the gas burner is ignited at the same time. And a control mechanism for controlling so as to stop the driving of the bathroom.

[0013]

[Function] When the reheating operation switch is turned on, the circulation pump in the fully automatic bath water heater is driven, and the gas burner is ignited at the same time, and the hot water in the bathtub is fully heated by the fully automatic bath water heater. It will be refired.

Next, the bathroom heating operation switch is turned on,
And when the reheating operation is not performed, the three-way valve is switched to the hot water mat side at the same time when the circulation pump of the fully automatic bath water heater is driven, and the hot water in the bathtub is changed from the bathtub to the reheating pipe → the circulation pump → It circulates through the heat exchanger in the non-heated state → reheating pipe → three-way valve → hot water mat → reheating pipe → bathtub, and the hot water mat generates heat with the hot water in the bathtub to heat the bathroom.

Next, when the reheating operation is being performed, the three-way valve is switched to the hot water mat side, and the hot water flows from the three-way valve into the bathtub via the hot water mat once.

Next, the bathroom heating operation switch is turned on,
When the temperature of the hot water in the bathtub is low, the gas burner is ignited simultaneously with the driving of the circulation pump in the fully automatic bath water heater, and the reheating operation is performed simultaneously with the heating of the bathroom. The above operations are all controlled by the controller.

FIG. 1 shows an embodiment of the present invention. Reference numeral 20 denotes a fully automatic bath water heater, which has a hot water supply function, a bath tub reheating function, and a heating function. However, in FIG. 1, only the reheating function is shown, and other functions are omitted. 21 is a heat exchanger of the fully automatic bath water heater 20, 22 is a gas burner, 23 is a gas valve, and 24 is a circulation pump. Reference numeral 26 denotes a reheating pipe, and reference numeral 27 denotes a bathtub. The reheating return pipe 25 and the transmission pipe 26 are connected to the bathtub 27 via a bathroom heating unit 28. The bathroom heating unit 28 has a three-way valve 29 attached to the reheating pipe 26, and the hot water mat 3
The hot water feed pipe 31 of the hot water mat 30 is connected to the hot water return pipe 32 and the hot water return pipe 32 of the hot water mat 30. In the figure, 25 'is a hot water return port, and 26' is a hot water outlet.

Reference numeral 33 denotes the inside of the bathroom heating unit 28,
In order to detect the temperature of hot water reaching the hot water mat 30,
A hot water temperature detection sensor attached to the hot water outflow pipe 31 is a reheating pipe 25 of the fully automatic bath water heater 20.
Is a hot water temperature detection sensor, 35 is a controller, 36 is a remote controller, and 37 is a room temperature sensor.

Next, an operation example of the above embodiment will be described. When the reheating operation of the bathtub 27 is turned on, the circulating pump 24 in the fully automatic bath water heater 20 is driven, and the gas burner 22 is ignited at the same time. It is re-fired at.

Next, a bathroom heating operation switch (remote controller 36)
Is turned on and the reheating operation is not performed, the circulating pump 2 of the fully automatic bath water heater 20 is operated.
At the same time as the 4 is driven, the three-way valve 29 is switched to the hot water mat 30 side, and the hot water in the bathtub 27 is changed from the bathtub 27 to the hot water inlet 2.
5 ′ → reheating pipe 25 → circulation pump 24 → heat exchanger 21 in non-heated state → reheating pipe 26 → three-way valve 29 →
The hot water outflow pipe 31, the hot water mat 30 → the hot water return pipe 32 → the reheating heating outflow pipe 26 → the hot water outlet 26 ′ → the bath tub 27 circulates, and the hot water mat 30 generates heat with the hot water in the bath tub 27 to heat the bathroom. .

Next, when the reheating operation is being performed, the three-way valve 29 is switched to the hot water mat 30 side, and the reheating water flows from the three-way valve 29 into the bathtub 27 via the hot water mat 30 once. .

Next, when the bathroom heating operation switch is turned on and the temperature of the hot water in the bathtub 27 is low, the fully automatic bath water heater 20 is turned on.
The gas burner 22 is ignited at the same time as the circulation pump 24 inside is driven, and the reheating operation is performed simultaneously with the heating of the bathroom. The above operations are all controlled by the controller 35.

[0023]

As described above, according to the present invention, the bathroom heating unit is attached to the bathtub, and the bathroom is heated by using the fully automatic bath water heater by switching the three-way valve.

A. The inside of the bathtub does not become narrow because the submersible pump is not built into the bathtub.

B. There is no electrical wiring in the bathroom.

C. All power is controlled by the fully automatic bath water heater, so there is no need for power in the bathroom.

D. Because the circulation pump of the fully automatic bath water heater is large, it can be used even if the hot water mat is large.

E. The room can be widely used because the remote control is only installed in a position where it does not interfere with the bathroom.

F. Since only a bathroom heating unit is to be installed, this is only a simple pipe connection, and equipment and construction costs are very low, and it can be used for existing facilities.
