There is. Connected to the outgoing pipe 4 are a pump 6 for circulating water in the water storage section 1 and for supplying hot water into the water storage section 1, and a heating means 7 for raising the temperature of the circulating water. Also connected to the return pipe 5 are water level detection means 8 for detecting the water level in the water storage section 1 and temperature detection means 9 for detecting the temperature of the circulating water. Further, a hot water supply source 10 is connected to a switching means 12 via a hot water supply pipe 11. The switching means 12 switches the connection of the outgoing pipe 4 to the return pipe 5 or the hot water supply pipe 11. Further, reference numeral 13 denotes a control means, which receives signals from the water level detection means 8 and temperature detection means 9 as input and determines each set value, and stores the memory in cooperation with the processor to control the pump 6. ,

As shown in 5 to S7, the hot water supply source l is heated up to the set water level of the water storage part l.
Hot water is supplied from O. At this time, the hot water is supplied by the pump 6 from the hot water supply source 10 through the hot water supply pipe 11 and the switching means 12 to the outgoing pipe 4.

ように加熱が行われ、316で入浴開始となる。When hot water is supplied to the set water level, the heating means 7 heats the hot water in the water storage section 1 until it reaches the set temperature, as shown in S8 to SIO. At this time, heating is performed by the pump 6 from the water storage section 1 through the return pipe 5 and the switching means 12 to the heating means 7, and the water is circulated through the outgoing pipe 4, the water storage section 1, and the pump 6. When heating is performed to the set temperature, as shown in 312 to S14, heating is performed to maintain the set temperature until the bathing starts at 318, and the bathing starts at 316.

、保温モードが長くなりエネルギーを浪費してしまう。In such a sequence, in order to start operation from the bath reservation time, the reservation time must be determined by subtracting the time until the water storage part 1 reaches the set water level and temperature from the time the user starts bathing. It is not convenient to use because the water storage part 1 does not reach the set water level and temperature, and the time it takes for the water storage part 1 to reach the set water level and temperature varies depending on the water temperature.
On the contrary, the water storage section 1 quickly reaches the set water level and temperature, and the heat retention mode becomes long, resulting in wasted energy.

になる時には貯水部1は設定水位、設定温度になる。As a means to solve such problems, a sequence as shown in FIG. 5 could easily be considered. When the operation is started at S1 and the reserved time is inputted by the external input means 14 at S2, the control start time is calculated at 319. This is done so that the water storage part l reaches the set water level and temperature at the reserved time.
The control start time is determined in advance by subtracting a certain amount of time from the reserved time. Then, when the control start time comes in S4, the hot water supply mode is switched on as in the sequence shown in Fig. 4.
It is operated in heating mode and heat retention mode, and when the reserved time comes in S15, the water storage section 1 reaches the set water level and temperature.

水部1の水位と湯温が設定値になるまでの時間である。Note that the constant value absorbs variations in the operating time value due to changes in water pressure and water temperature, and is set to, for example, 5 minutes in this embodiment. The operating time value is the time from when the control means 13 starts control until the water level and hot water temperature in the water storage section 1 reach the set values.

時間を決定すれば良い。Considering that there may be some residual water in the water storage part from the previous time, there may be variations in the operating time values, so select the largest operating time value from the operating time values from the last time to several times in the past. The control start time may be determined by adding a constant value to this value.

加熱される。Next, when the control start time comes at 84, hot water is first supplied from the hot water supply source IO up to the set water level of the water storage part l as shown in 35 to S7. It passes through the switching means 12 to the outgoing pipe 4. When hot water is supplied to the set water level, the heating means 7 heats the hot water in the water storage part 1 until the temperature reaches the set temperature, as shown in S8 to SIO. At this time, heating is carried out by the pump 6 from the water storage part l through the return pipe 5 and the switching means 12 to the heating means 7.
The water is circulated through the outgoing pipe 4, the water storage section 1, and the pump 6. Here, the water storage section 1 reaches the set water level and temperature, and the total time of hot water supply mode operation and heating mode operation of 35 to SIO is calculated and stored as an operation time value in Sll, and the past several times for the next operation are calculated and stored as an operation time value. Furthermore, as shown in S12 to S]4, the bath is heated to maintain the set temperature until the reserved time is reached in S15 and bathing starts in 316.
