Conventionally, when there is a large amount of high-temperature residual water in the bathtub than necessary due to over-boiling, etc., the user can reduce the high-temperature residual water to an appropriate level before refilling the bathtub, or leave it for a long time. If there is an unnecessarily large amount of low-temperature residual water in the bathtub due to reasons such as this, the user should first reduce the low-temperature residual water to an appropriate water level and then supply high-temperature hot water to reach the desired water level while avoiding overflow. (I am unable to provide references).

In other words, by reducing residual water at a certain temperature to an appropriate water level, the desired hot water filling state (water filling state at a set water level Hp and a set temperature tp) can be obtained by supplying water or hot water at a certain temperature after the water reduction. If so, the above-mentioned appropriate water level at which the remaining water should be reduced in advance, that is, the target water reduction water level Hl, is determined by the above-mentioned set water level Hp and set temperature tp, as well as the temperature of the remaining water detected by the water temperature detection means. If tx and the water or hot water supply temperature ti are given, it can be determined from the calorific balance relationship as shown below.

Water level Hl
If the remaining water is automatically drained to the target water reduction level H L by the automatic operation of the drain valve device based on the information detected by the water level detection means, the user's intuitive judgment as in the past can be avoided. In addition, the remaining water reduction operation can be easily and accurately completed without any artificial start/stop operations of drainage.

In either case, the water level sensor 5 and water temperature sensor 6 attached to the bathtub 1 Detected residual water level Hx (when there is no residual water in bathtub 1)
Based on Hx=0) and temperature tx, the required water supply amount and required heating amount required to obtain the desired hot water filling state at the set temperature tp at the set water level Hp set by the user are calculated. Based on the heating capacity adjustment, the hot water supply temperature to is adjusted to a temperature such that the bathtub water temperature becomes the set temperature tp when the bathtub water level reaches the set water level Hp, and the detected bathtub water level Hx becomes the set water level Hp.

The time required to reach this point is minimized. However, if the required hot water supply temperature to cannot be secured in terms of heating capacity even if both the water heater 2 and the bath pot 3 are operated (for example, when the water temperature ti entering the water heater 2 is quite low in winter), Water heater 2 and bath pot 3

ていない風呂装置に特に有効である。 In the above-mentioned embodiment, when there is an unnecessarily large amount of high-temperature residual water in the bathtub 1, and the water level in the bathtub exceeds the set water level Hp before the bathtub water temperature drops to the set temperature tp by simply supplying water, Although the solution (automatic low-temperature hot water filling) has been shown, the present invention solves the problem when there is an unnecessarily large amount of low-temperature residual water in the bathtub.
It can also be applied to the case where the bathtub water level exceeds the set water level Hp before the bathtub water temperature rises to the set temperature tp even if hot water is supplied to the maximum temperature from the water heater, and in that case, the following (a) In the formula, H L = Hp・(tp−ti)/tx−ti……(a) Hp: Set water level tp: Set temperature tx: Detected residual water temperature Substitute the hot water temperature for ti to find the target water reduction level H L , and the low-temperature residual water may be automatically drained up to the target water reduction level H L , and this type is particularly effective for bath equipment equipped with only a water heater as a bathtub water heating means.
