終了するように構成されている（Ｓ９，Ｓ１０）。(Prior art) In order to improve the durability of the pump and save energy, forced circulation bathtubs periodically detect the water temperature and keep the water temperature within an allowable temperature range based on a predetermined set temperature. It is customary to control the For example, as shown in Japanese Utility Model Application Publication No. 60-59032 and Figure 3, a predetermined waiting time is
Every time To elapses (S1), the circulation pump is activated (S2), and when a certain period of time (here, 1 minute) has elapsed since the start of the pump (S3), the water temperature Th is detected using a thermistor, etc. (S4 ), after determining whether the hot water temperature Th is lower than the set temperature Ts, (S
5) If the hot water temperature Th is higher than the set temperature Ts, the pump is stopped and the hot water temperature control sequence is terminated (S
6) If the hot water temperature is lower than the set temperature Th, the combustion device is activated to heat the hot water (S7), and when the hot water temperature reaches the set temperature Th (S8), the combustion device and pump are activated. It is configured to sequentially stop the hot water supply and complete the hot water temperature setting control sequence (S9, S10).

なつたり、無駄にポンプが運転されてエネルギを
充分に節約できないといつた問題がある。 In such a conventional method of controlling the water temperature of a forced circulation bath pot, the interval at which the water temperature control sequence is executed is constant, so depending on the season, the water is strongly cooled during that time and the water temperature does not reach a predetermined temperature. The temperature may become lower than the temperature range, or conversely, the hot water may not be cooled much during that time, and the heat retention cycle without combustion may be repeated many times. Therefore, there are problems such as the accuracy of hot water temperature control becoming low and the pump being operated unnecessarily, making it impossible to save sufficient energy.

4 is a burner, 5 is a circulation pump, 6 is a circulation pipe, and 7 is a hot water temperature detector. 8 is a control device. Reference numeral 9 denotes a water heater, which has a water flow sensor 11 and a water flow temperature detector 12 in a water inlet pipe 10, and controls the gas flow rate in a feed forward manner. Reference numeral 8 denotes a control device for controlling the bathtub 2 and the water heater 9.
次に第２図に従つて作用を説明する。 Next, the operation will be explained according to FIG.

行うのである（Ｓ１７）。 The bath burner 4 is combusted (S11), and when the circulating water temperature Ts becomes equal to or higher than the set temperature Th (S12), combustion is stopped (S13). Here, the inlet water temperature Tc is taken in by the inlet water temperature detector 12 of the water heater 9 (S
14) Set the waiting time To as a function of the inlet water temperature Tc (S15). Then, a heat retention standby timer is started (S16). Then, when the timer times up, the bath returns to its original state and starts burning the bath (S17).

耐久性を高めることができる。 In the above configuration, since the inlet water temperature changes depending on the air temperature, the intensity of cooling (cooling state) can be detected by detecting this temperature.
The stronger the cooling intensity, the longer the waiting time will be.
To is set short, and the hot water temperature detection and subsequent hot water temperature control sequence are repeated frequently. As a result, it is possible to prevent the water temperature from dropping significantly below the permissible range during winter and the like. In addition, during seasons such as summer when the cooling intensity is weak, the standby time is set longer.
The number of times the pump is operated to detect hot water temperature can be reduced to the minimum necessary, thereby further saving energy and increasing the durability of the pump.
又、凍結防止の為に設けられている気温検出器
の出力を利用してもよい。 Alternatively, the output of a temperature detector provided for freezing prevention may be used.
