In this type of bathtub, a bathtub (water heater) and a waiting tub are formed adjacent to each other via a partition door (shielding plate). If you open the partition door when you move, it is inevitable that hot water will flow from the bathtub to the waiting tub. Therefore, this kind of bathtub is desirably formed so that the hot water flowing into the waiting tub side can be comfortably bathed without wasting.

However, in the conventional product, no countermeasures were taken against hot water flowing from the bathtub to the waiting tub when the partition door was opened. Therefore, according to the conventional product, the water level dropped due to the outflow to the waiting tub during bathing. There is a problem in that it is necessary to add hot water to the bathtub, and if the shield plate is opened when going out, the hot water in the waiting tub is drained.

[0005] Conventionally, for example, there is a type in which a plurality of bathtubs are provided, the bathtubs are connected to each other by pipes, and hot water can be transferred by a pump (for example, see Japanese Patent Application Laid-Open No. 3-26221). ).

However, in the case of this conventional product, since each bathtub is individually arranged in the bathroom, it is inevitable that a large installation space is required. Therefore, according to this, there is a problem that it cannot be used unless the building has a dedicated wide bathing facility, such as a nursing home or a welfare facility, and cannot be installed in, for example, a bathroom of a general home where space is limited.
