2. Description of the Related Art Baths using a hot water supply mechanism using city gas, oil, electricity, etc. as heat sources are often used. At the same time, the sauna, clothes, and futon dryer use electric heat as a direct heat source, and are installed independently regardless of the bath or bathroom.

[0003]

[Problems to be Solved by the Invention] Commercially available saunas, clothes and futon dryers use electric heat as a direct heat source.
For this reason, installation in the bathroom is prohibited by the Electrical Appliance and Material Control Law. Therefore, the sauna, clothes, and futon dryer are installed outside the bathroom independently of the bath. In view of this, in the present invention, a hot air generator is installed outside the bathroom to circulate the hot air inside the tank and use it as a heat source. Thus, saunas, clothes, and futon dryers are constructed using bathtubs that retain the functions of a bath. The heat source of the hot air generator may be hot water of the hot water supply mechanism of the bath or electric heat.

[0004]

[Means for Solving the Problems] 1). While maintaining the function of the bath, a hot air generator is installed outside the bathroom to circulate the hot air inside the bath and use it as a heat source. 2). A sauna room is constructed by forming an air curtain on the upper part of the bath and using the lid of the bath as it is, and the hot air is circulated to form a sauna. 3). A detachable room space is formed in the upper part of the bathtub to form a drying room together with the bathtub, and warm air is circulated to form clothes and futon dryers.

[0005]

[Operation] 1). The function as a bath or bathtub is the same as before. 2). A hot air generator is installed outside the bathroom to circulate the hot air in the bathtub as a heat source. Therefore, you can freely combine baths and saunas, baths and clothes, futon dryers, etc. 3). The inner wall of the bathtub is always 50 ° -60 ° C due to warm air circulation.
Is kept at. Therefore, a large amount of long-wave infrared rays (far infrared rays) is radiated from the wall surface, which is absorbed by the human body, clothes, futons, etc., and is combined with warm air to enhance the heating effect. 4). The warm air blows out evenly from the bottom of the bathtub, and the human body, clothes, and futon are easily contained in the flow of this warm air, and together with the infrared rays emitted from the inner surface of the bathtub, each part is heated evenly and quickly. To do. 5). The inner wall of the room space that is detachably formed on the upper lid of the sauna room, the clothes, and the upper part of the bathtub of the futon dryer is aluminum vapor-deposited, and the infrared rays emitted from the lower part are reflected to the bottom again. Have returned to. For this reason, the infrared effect is great and the heat loss on the inner wall is small. Therefore, the infrared effect is great and the waiting time at the start of heating is shortened.
