[0019]
Next, FIG. 5 shows a case in which bathing and heating of the bathtub are operated at the same time. When the chasing and heating switch operation is performed with the remote controller of the hot water bath 12, the switching mechanism 14 causes the circulation port 8 and the bathtub 3 to be connected. In this case, the A part, the B part, and the C part of the three-way valve 21 are opened, and the on-off valve 22 is turned on. Open state. By driving the remedy pump 25, the bath water passes through the tub return pipe 32 from the circulation port 8, is sucked in through the circulator water tank 29 through the on-off valve 22, and is heated in the remedy combustion unit 24. The hot water for remedy flows in the direction C of the three-way valve 21, the hot water for heating flows in the B direction of the three-way valve 21, and the hot water for remedy passes through the bathtub outlet pipe 31 to the bathtub 3 through the circulation port 8. And flows in. Thereafter, the bathtub water flows from the circulation port 8 through the bathtub return pipe 32 and the opening / closing valve 22 into the circulation water tank 29. On the other hand, the heating hot water flows from the heating forward pipe 33 through the heating panel 37 to the circulating water tank 29 through the heating return pipe 34. Here, the memorial combustion unit 24 detects the hot water return temperature of the circulating water tank 29 so that the set temperature of the hot water of the bathtub 3 and the heating circulation hot water can be maintained, and does not burn or burn it.

[0020]
In the embodiment shown in FIGS. 1 to 5 described above, hot water heated in the combusting combustor 24 is added by one three-way valve 21 and one on-off valve 22 provided in the switching mechanism 14. It is branched into a soot channel and a heating channel, and then merges in the circulating water tank 29, is sucked in by the chasing pump 25, and returns to the chasing combustion unit 24. That is, the hot water circulation circuit is a parallel circuit. Since warm water flows through the circulation port 8 and the heating panel 37, respectively, heat loss is less than that of a series circuit configuration, and efficient operation is possible. Further, in the configuration of this embodiment, since the number of the three-way valves 21 is one, the structure is easy and can be manufactured at low cost.
[0021]
As shown in FIG. 5, the switching mechanism 14 shown in FIGS. 1 and 2 is configured to be switched by one three-way valve 21 and one on-off valve 22 as shown in FIG. In addition, either a configuration that switches with one three-way valve 21 or a configuration that switches with two on-off valves 22 as shown in FIG. 6 can be adopted.
[0022]
FIG. 7 shows a piping path through which circulating water enters the heating panel 37 via the three-way valve 21 in the switching mechanism 14 from the combusting combustor 24 through the heating forward pipe 33, and the piping from the three-way valve 21 to the heating panel 37. In this embodiment, a bypass pipe 35 connected to the heating return pipe 34 is provided.
Normally, the amount of circulation when performing reheating in the hot water hot water bath 12 is 6 to 9 (liters / minute). In order to prevent the heat exchanger from being blown and to ensure safety, the hot water supply flow path and the revolving flow are used. A sensor such as a water flow switch 36 for detecting running water is provided on the road. However, the amount of water set by which the water flow switch 36 detects the water flow varies.
[0023]
On the other hand, since the amount of water flowing through the hot water circulation pipe 5 in the heating panel 37 is a relatively small circulation amount of 1 to 4 (liters / minute), the water flow switch 36 detects flowing water in the case of heating independent operation. In such a case, the water circulates through the hot water circulation pipe 5 in the heating panel 37 in a state where no additional combustion is performed and the circulating water is not heated.
Therefore, in the embodiment shown in FIG. 7, the hot water from the combusting combustion section 24 flows to the bypass pipe 35 of the heating forward pipe 33, and the same amount of water flows as the additional circulation amount. It branches into the flow path to 37 and the flow path to the heating return pipe 34.
[0024]
Thereafter, the circulating water that has passed through the heating panel 37 flows from the outlet of the hot water circulation pipe 5 to the heating return pipe 34, and joins with the circulating water from the heating forward pipe 33 in the bypass pipe 35. Thus, the amount of the recirculated water in the hot water hot water bath 12 can be made constant regardless of the operation state of the memorial single operation, the single heating operation, and the simultaneous operation of the memorial and heating. it can.
[0025]
In the present invention, a hot water bath 12 is fitted from the inside of the bathroom into a square hole for an air supply / exhaust port on the outer wall of the bathroom and fixed to the bathroom wall surface, and the main body part is projected outdoors, and piping for hot water, water, gas, etc. Although the connection part is installed on the wall side in the bathroom, it has a through-wall installation type. However, it is possible to use an outdoor stationary hot water bath with a hot water supply panel in order to use the circulation pump provided for the bath. It is.
In addition, when the outer wall penetration type hot water bath with hot water supply is used as in the embodiment of the present invention, both the wall through water bath with hot water supply and the heating panel 37 are located inside the bathroom 4. Therefore, the work from construction to maintenance can be simplified, the heating circulation pump for circulating hot water can be miniaturized, and the circulation path is shortened, so that the heat radiation loss during heating can be reduced. An effect is obtained.
In the embodiment, the heating panel 37 is arranged on the floor surface of the washing place of the bathroom 4, but the installation location is not particularly limited as long as it is inside the bathroom 4.
