ようにするためである。尚、前述のＴ。<Prior Art> This type of water heater generally supplies hot water by dropping hot water from the water heater through piping into the bath, and the hot water supply side is comprised of a semi-hot water storage tank. When supplying hot water to a bath, the temperature setting of the water heater is automatically switched from the temperature setting for normal hot water supply to the temperature adjustment set temperature 'rys for bath hot water supply, and the off set temperature T of the hot water supply side burner is set. FF TOFF=TFS TI% ON Set temperature TON T. Set N=TOFF THI and this ON setting temperature T. , and off set temperature T. FF
The burner on the hot water supply side is controlled on and off according to the temperature, and the temperature of the hot water supplied to the bathtub is adjusted. The reason why the bath temperature control set temperature TF3 is shifted to lower than TF3 is that because it is a semi-hot water storage tank, the remaining high temperature water is dropped into the tank at the beginning of hot water supply, and the temperature sensor on the hot water supply side and the bath side This is to prevent the bath temperature control set temperature bs from exceeding even if there is a difference in characteristics with the temperature sensor. In addition, the above-mentioned T.

調設定温度以下となる問題がある。<Problems to be solved by the invention> However, if a water heater is used in the kitchen or the like at the same time as hot water is poured into the bath, the heat exchange rate changes as the amount of water changes, causing the bath temperature to change. There is a drawback that the difference from the adjusted temperature becomes large and the automatic reheating time after automatic hot water supply to the bath becomes long. In addition, when water retention starts while taking a bath, the water temperature in the bathtub decreases due to the supply of hot water with a temperature considerably lower than the above-mentioned bath temperature control setting temperature, causing discomfort to the bather. In addition, there is a problem in that the water temperature in the bathtub remains below the temperature control setting temperature until the automatic reheating is finished.

される。When the water level of the bathtub reaches a predetermined water level, the circulation pump is activated and the detected temperature is subtracted from the polarity of the temperature difference between the temperature control set temperature for the bath and the detected temperature of the bath water temperature, that is, the temperature control set temperature. If the difference temperature is a value of 10, add the difference temperature to the temperature control set temperature to set the off set temperature of the hot water supply side burner, and if it is a negative value, add the difference temperature to the temperature control set temperature. The off set temperature is set by subtracting the temperature. Therefore, even when the water heater is used for automatic bath water supply and normal hot water supply at the same time, correction is made to maintain the dropped hot water at approximately the temperature control set temperature.
