水を沸す様にしたものである。<Conventional technology> Conventionally, this type of bathtub was developed in the 1970s, for example.
There is one disclosed in Publication No. 58644.
In such a bathtub, a heating heat exchanger (heat exchange section) is installed by closely attaching pipes to the outer surface of the tank wall at the bottom and lower side walls, and high-temperature hot water is circulated from the hot water source to the heat exchanger. The bathtub water is heated by heat transfer from the inner surface of the bathtub wall.

すことが出来る。 A heat exchange section is formed by attaching bellows-shaped metal pipes in multiple stages along the inner peripheral surface of the lower part of the side wall of the bathtub body, and a protective cover covering the heat exchange section is extended from the bottom wall of the bathtub body to the side wall. At the same time, a communication passage is provided between the upper edge of the protective cover and the side wall and between the lower edge of the protective cover and the bottom wall to communicate the heat exchange chamber and the inside of the tank, on the inner peripheral surface of the lower part of the side wall. Because it is installed across the body, the bath water can be heated and boiled while directly exchanging heat with the bath water in the heat exchange chamber. It is possible to boil water in the bathtub by supplying it in circulation.

とができる浴槽を提供でき、有益である。 The bathtub water (hot water) heated in the heat exchange chamber flows out into the tank from an upper communication passage that opens along the entire inner circumference of the side wall, and as it flows out, it flows into the bathtub from a lower communication passage that opens around the bottom wall. When the water flows into the heat exchange chamber and is heated, the natural convection in the vertical direction is generated around the entire lower part of the side wall of the bathtub body, allowing the bathtub water to boil. It is advantageous to be able to provide a bathtub in which heat exchange is performed effectively and the bathtub water can be boiled efficiently in a short time.
