ある。 [Means for Solving the Problems] Technical means for solving the above-mentioned problems include a water heater that heats water supplied from the outside to hot water of a set temperature and sends the water, and the hot water sent from the water heater. In the radiator that blows warm air into the bathroom by heat exchange with the hot water when the water is circulated, and in the first bypass circuit that bypasses the radiator or the hot water sent from the water heater. A first three-way valve capable of switching control for flowing, and a second bypass circuit for directing hot water from the first bypass circuit and the radiator to a bathtub of the same bathroom, or bypassing the bathtub and directly returning to a feedback circuit. In a bathroom heating / drying system including a second controllable second three-way valve for flowing into the air, a semi-hermetically absorbing expansion and contraction of hot water from the radiator in the middle of the second bypass circuit. Tank and the bath and the semi-closed tank
A pipe line connected between the tanks is provided , and a two-way valve capable of opening / closing control is provided midway in the feedback circuit closer to the bath than a connection point where the second bypass circuit and the feedback circuit are connected , For bathroom heating and drying mode when there is no water in the bathtub
Control so that the two-way valve is closed,
In the process of circulating between the water heater and the radiator, the hot water
Absorbs hot water inside the semi-sealed tank when expansion occurs
However, the amount of hot water that cannot be absorbed inside flows out to the above-mentioned pipeline.
By absorbing the expansion of hot water,
If water contracts, from inside the semi-enclosed tank,
Alternatively, the water accumulated in the above-mentioned pipeline is passed through this semi-sealed tank.
Therefore, by replenishing the hot water and absorbing the shrinkage of the hot water,
is there.

When the bathroom heating / drying system enters the heating mode / drying mode operation with the one-way valve closed, the hot water from the water heater flows through the radiator and then the second three-way valve and the semi-closed tank It is circulated by a circuit that flows through the feedback circuit and returns to the water heater. In this circulation process, expansion and contraction of hot water is absorbed by the semi-enclosed tank, so the hot water is circulated smoothly and the two-way valve is closed so that hot water does not flow into the bath from the feedback circuit. Therefore, even if there is no water in the bathtub, hot air is continuously blown into the bathroom from the radiator without stopping the heating mode / drying mode operation.
