That is, it has a bath circuit that forcibly circulates bath water by a pump and a drop-in hot water supply circuit connected to the bath circuit, and a water level sensor that communicates with one of the reciprocating piping forming the bath circuit; A valve is provided to shut off a flow path between the water level sensor and the pump, and the valve is closed while hot water is being supplied to the bathtub from the other pipe via the pump, and the water level in the bathtub is detected by the water level sensor. ing.

内に配置することもできるのである。(Function) Hot water from the drop-in hot water supply circuit is pressurized by a pump and sent to the bathtub from one of the reciprocating pipes forming the bath circuit. The water level sensor receives pressure based on the bath water level via the other pipe, and the flow path between the water level sensor and the pump is blocked by a valve, so it is not affected by the pump's discharge or suction force. Therefore, while hot water is being force-fed into the bathtub from one pipe, the water level in the bathtub can be detected via the other pipe. Therefore, the water level sensor can also be placed within the device body.

に記憶させる。In the embodiment with the above configuration, a test run is performed when the construction is completed, hot water is supplied to the bathtub (4), and once the water level in the bathtub (4) reaches the minimum water level (LMIN) at which bathing is possible, the hot water supply is stopped. Then, the output value (PMIN) of the water level sensor (9) at that time is stored in a storage circuit (not shown) of the controller.

2) Supply hot water heated in step 2). When the water level inside the hopper (16) reaches the upper limit, the float switch (21) detects this and closes the automatic hot water supply solenoid valve (17), and also opens the solenoid valve (22) and solenoid valve (8). and hop (7)

な水量センサを用いる無駄を排除できるのである。Then, the hot water in the hopper (16) mainly flows from the connecting pipe (23) through the pump (7) to a bypass path with low water flow resistance (
10). This is because the bath heat exchanger (3) has a pipe wound around the outer periphery of the heating side and a fin pipe-shaped heat absorbing part formed inside the heating side, so it has many bent parts and the water flow resistance is low. The hot water discharged from the pump (7) reaches the bath heat exchanger (3) and then flows to the bypass path (10) where water flow resistance is small. Hot water flows from the bypass path (10) to the water flow switch (
11) flows back through the return pipe (6) to the bath M (4). When the water level in the hopper (16) reaches the lower limit, the float switch (21) detects this number and stops the pump (7), as well as closes the solenoid valve (22) and solenoid valve (8), and closes the solenoid valve for automatic hot water supply. (17) is established. In this way, hot water is again supplied to the upper limit water level of the hopper (16) and sent to the return pipe (6) via the bypass path (10). The above operation is repeated several times to fill the bypass passage (10) and return pipe (6) with hot water and to discharge air from the bath adapter (24). The number of times to repeat varies depending on the construction site depending on the length of the piping, etc., so it is determined during the trial run described above and stored in the controller. In addition, the hot water supply pipe for the bath (
15) Alternatively, a water flow rate sensor may be provided in the connecting pipe (23) or the like to measure the flow rate necessary for discharging the air. By using the hopper (16), which is essential to prevent the danger of water flowing back into the city water pipe, the waste of using expensive water flow sensors can be eliminated.

弁（２２）を閉成しポンプ（７）を停止させる。When the air exhaust operation is performed a predetermined number of times and the path from the water level sensor (9) to the bus adapter (24) is filled with hot water, the solenoid valve (8) is closed and the output of the water level sensor (9) is sampled. This air evacuation operation is always performed at the beginning of automatic hot water supply, so if there is hot water remaining in the bathtub (4), the set water level (set by a setting means such as a remote control not shown) has already been reached at this point. If so, automatic hot water supply will be stopped, but if not, the automatic hot water supply solenoid valve (17) and solenoid valve (22) will be opened and the pump (7) will be operated to turn on the bath heat exchanger (3). Hot water is supplied through four routes from the outgoing pipe (5) to the bathtub (4). While hot water is being supplied through this route, the output of the water level sensor (9) is sampled;
4) Until the water level in the return pipe (6) reaches the bath adapter level (LBA), there is a risk that the hot water filled in the return pipe (6) will be replaced by air entering from the bath adapter (24), and if the piping If air is present in the middle, the water level sensor (9
) cannot accurately detect the water level, so at least the output of the water level sensor (9) is used to detect the water level! Until it is confirmed that the water level in (4) has exceeded the bus adapter level (LBA), the solenoid valve (8) is opened at regular intervals and the water is returned to the return pipe (6) side via the bypass path (1o). Supply hot water. That is, hot water is sent out alternately from the outgoing pipe (5) side and the return pipe (6) side. However, if the solenoid valve (8) is opened and the return pipe (
6) While supplying hot water from the water level sensor (9), the pump (7) is connected to the water level sensor (9).
Since the discharge pressure of the water level sensor (9) is transmitted, the output of the water level sensor (9) is not sampled.
6) The time for supplying hot water from the side is kept as short as possible. The pressure due to the water level in the bathtub (4) is only applied while hot water is being supplied from the outgoing pipe (5) side, and the output of the water level sensor (9), which can continuously sample the output, is equal to the minimum water level (L). The output value (p
S K T) and if an output equal to or higher than the output value (psET) is detected, the automatic hot water supply solenoid valve (17) and the solenoid valve (22) are closed and the pump (7) is stopped.

4) Regardless of the presence or absence of hot water remaining in the piping, or even if air has initially entered the piping, the water level can be stopped extremely accurately at the desired water level.

吸引圧力の影響を受けるから水位の検出は行わない。In addition, in order to reheat the hot water in the bathtub (4), the valve (25) is opened and the pump (7) is operated. Return pipe (6)
The bath water sucked in from the bathtub is heated by the bath heat exchanger (3), which is heated by a signal from the water flow switch (11), and then reaches the bathtub (4) from the outgoing pipe (5), where it is heated by the water temperature sensor (12). When it detects a preset temperature, it automatically stops this circulating heating. In addition, during this rear-end collision, the valve (25)
Since the water level sensor (9) is open, the water level sensor (9) is affected by the suction pressure of the pump (7) and therefore does not detect the water level.
また、本発明では入浴時に浴湯を使用することによる浴
槽（４）の水位の低下を検出し、設定水位まで自動的に
補水することが可能である。Further, in the present invention, it is possible to detect a drop in the water level of the bathtub (4) due to the use of bath water during bathing, and automatically replenish the water to a set water level.

The system repeatedly stops and enters a chattering state.
