(3), water level gauge (24) for detecting the water level in the bathtub, and heat exchanger
A water filling circuit (21) pipe-connected from (22) to the bathtub (2),
A water filling valve (23) which is inserted into the water filling circuit (21) and which is opened by a closing signal of the water filling switch (3) and closed by a water filling completion signal output from the water level gauge (24). In a hot water filling device comprising a hot water temperature setting device (4) for setting a desired bath temperature, and a hot water temperature control circuit (61) for controlling the temperature of hot water supplied from the heat exchanger (22), The drainage circuit (31) for communicating the inside and outside of the bathtub (2), the drainage valve (33) and the water temperature sensor (32) arranged in the drainage circuit (31), and the drainage after the water filling switch (3) is turned on. There is a timer (35) that keeps the valve (33) open for a certain period of time, and a replenishment water temperature calculation circuit (37) that determines the temperature of replenishment water to be added to the bathtub (2) by the following calculation. The water temperature detected by the water temperature sensor (32) after a certain time has elapsed since the (33) was opened is t2, and the water level gauge (2
When the water level of residual water detected by 4) is h2, the water filling temperature set in the water temperature setting device (4) is t, and the water filling target water level is h, replenishment is performed by the replenishment water temperature calculation circuit (37). Water temperature t1
= (Ht-h2 * t2) / (h-h2), and the supplementary water temperature t1 obtained as a result of the calculation is applied to the hot water temperature control circuit (61). Hot water filling device.
