ものであつた。(Prior Art and Problems) Conventionally, in a one-can, two-circuit type bathtub circulation heating device with hot water supply in which the heating pipe for circulation and the heating pipe for hot water supply share a fin, there is a method disclosed in Japanese Utility Model Publication No. 53-30433. The hot water supply circuit, which is a sealed circuit when not in use, was drained to prevent boiling.
However, if the bathtub and bath heat exchanger are configured with a circulation circuit with a circulation pump interposed, a natural circulation path is not formed, so if hot water is used while the circulation pump is stopped, the circulation circuit will be damaged. There was a risk of boiling. However, draining the water in order to prevent boiling as in the conventional example described above could not be adopted because it would lead to a decrease in water in the bathtub.

である。(Means for Solving the Problems) In order to solve the above problems, the present invention has a hot water supply heat exchanger placed above the bathtub, a hot water heat exchanger placed above the shared fin, and a bath heat exchanger placed below the shared fin. A bathtub heat exchanger and a bathtub are connected to each other by a circulation path with a circulation pump interposed therebetween, with a main body having a one-can, two-circuit type can body. A check valve is interposed and an automatic air supply device is provided in the circulation path between the check valve and the bath heat exchanger.

ることはなくなり、沸騰もしなくなる。(Operation) When the circulation pump is stopped, no discharge pressure is applied to the downstream circulation path. Moreover, since the bathtub, which is open to the atmosphere, is located below the main body, the circulation path downstream of the circulation pump has negative pressure. The automatic air supply system then opens and sucks air into the circuit to prevent water from accumulating in the heat exchanger. Therefore, even if hot water is supplied when the circulation pump is stopped, the circulating water will not be heated and will not boil.

る。 The present embodiment has the above configuration, and when performing circulating heating of the bathtub 1, the bath operation switch 22 is closed. Then, the circulation pump 16 is energized via the normally closed switch 25, and the operation of the circulation pump 16 causes the bathtub water to circulate between the bathtub 1 and the bath heat exchanger 5 via the circulation path 15. 1
7 is detected, the gas electromagnetic valve 7 is opened by energization, and the gas burner 6 is ignited by an ignition device (not shown) to combust and circulate and heat the bath water. If you want to supply hot water next time, just open the hot water faucet 10 in the kitchen or the like. When this tap is opened, a water flow is generated in the hot water supply circuit, the water switch 11 is closed, and the relay 23 is activated. Due to the operation of the relay 23, the normally closed switches 24 and 26 are closed and the normally closed switch 25 is opened, so that water in the bathtub is not circulated, but the gas electromagnetic valve 7 is opened, the gas burner 6 is combusted, and hot water is supplied. Also, while the circulation pump 16 is operating, the water pressure in the circulation path 15 is high, and as shown in FIG. When the circulation stops, the pressure inside the circulation path 15 decreases, and as shown in FIG. Therefore, the water in the bath heat exchanger 5 is replaced with the invading air, and the water in the circulation path 15 downstream of the check valve 18 escapes into the bathtub 1 below the main body, and the water in the circulation heat exchanger 5 is replaced by the invading air. Water does not stagnate.

The influence of heat on the inside of the bathtub 4 is not a problem because most of the circulating water absorbs heat, but since the bath heat exchanger 5 is configured to receive a lot of combustion heat from the gas burner 6 during hot water supply, the inside of the heat exchanger 5 Stagnant water boils,
Extremely inconvenient phenomena occur, such as the main body 2 vibrating, water spewing out into the bathtub 1, and water in the heat exchanger 5 evaporating and forming scale.

く、極めて実用効果の大なる考案である。 In contrast, in the present invention, as mentioned above, a check valve is interposed in the forward direction in the circulation path downstream of the circulation pump, and an automatic air supply device is installed in the circulation path between the check valve and the bath heat exchanger. Therefore, when hot water is supplied, the accumulated water in the bath heat exchanger is replaced with air entering from the automatic air intake device and drained into the bathtub 1. Therefore, unlike the conventional example, the circulating water does not boil when hot water is supplied. Moreover, the problem of scale formation in the bath heat exchanger 5 is also eliminated. Moreover, in the present invention, the circulation path 15 upstream of the circulation pump 16 is not drained because the check valve 18 blocks air entry, and there is no need to prime the circulation pump 16 again during recirculation, which is extremely practical. This is a great idea.
