Description

[Detailed Description of the Invention] The present invention relates to a new type of sauna box that uses residual heat from a heater to emit far-infrared rays from all sides of the sauna box's inner surface.

In conventional sauna boxes, the heat source consists of the heater itself installed inside the sauna box, and the radiation of far-infrared rays emitted from the heater, convection of air inside the sauna box, etc.
It was warming the human body inside the sauna box. However, in the case of the conventional method, as shown in Figure 1, the immediate radiation from the heater 1 and the radiation from the reflector 2 hit the human body from one direction, making it difficult to warm the human body evenly. In addition, there was a problem that the temperature in the sealed space 5 between the reflector 2 and the inner surface of the heater box 3 covered with the heat insulating material 4 could rise abnormally.

In order to solve the above problem, the present invention makes the walls of the sauna box hollow, coats the sauna room side with ceramic, and communicates the inside of the heater box with the hollow part of the wall to release residual heat inside the heater box. is introduced into the wall and warms the wall itself, causing far-infrared rays to be emitted from the ceramic on the inner surface.

Preferred embodiments of the sauna box of the present invention will be described below with reference to the drawings.

Figures 2 and 3 show cross-sectional views of the sauna box of the present invention. In the figures, reference numeral 10 is a wall, which extends from the four side walls 10a, 10b, 10c, and 10d, the ceiling wall, and the floor plate wall. Become. The inside of the wall 10 is formed hollow, and a core material 11 is inserted at key points, but a large number of ventilation channels 13 are perforated in the core material 11 so that the spaces 12 inside the wall communicate with each other. It is set up. The illustrated sauna box is shown as a box in which a front wall 10a, a rear wall 10b, a pair of side walls 10c, 10d, etc. are rigidly fixed to each other, but the box is not limited to a fixed type. It may also consist of a foldable box.

The inner surface of the wall 10 of the sauna box is coated with ceramic material, as shown in FIG.
In this ceramic layer 14, the inner wall of the wall 10 is made of metal.
It is made of cloth, plastic, wood, etc., and is formed by coating the inner surface of the material. The ceramic layer 14 emits far infrared rays when the back wall 10 is heated, and the ceramic layer 14
The part where is formed functions as a surface heater.

A heater device 15 is installed inside the sauna box, as shown in an enlarged view in FIG. The heater device 15 usually consists of a pair of heaters located at both front corners of the interior of the sauna box, and one back heater embedded in the rear wall 10b. The heater device 15 includes a heater body 16 that is usually a rod heater or the like;
It consists of a reflector plate 17 provided on the back of the heater body 16 to reflect far-infrared rays toward the human body, and a heater box 18 that houses them. A space within the heater device 15, for example a space 19 formed between the reflector 17 and the heater box 18, is communicated with the space 12 within the wall 10 through a ventilation hole 20. The air flow through 20 allows heated air in the space 19 of the heater device 15 to circulate into the space 2 in the wall 10. For example, if the ventilation holes 20 are provided at the upper and lower parts of the heater device 15, the air heated in the space 19 will enter the space 12 in the wall 10 through the upper ventilation hole 20, and
0, it cools down and naturally moves downward, enters the space 19 inside the heater device 15 through the ventilation hole 20 at the bottom, where it is heated again on the back side of the reflector plate 17 and rises upward. The so-called natural circulation becomes possible. Further, holes 22 may also be provided in the inner wall.

A large number of fins 21 are provided on the surface of the wall 10 facing the hollow space 12, as shown in FIG.
By doing this, the heated air is transferred to space 1.
When the air flows into the wall 10, the contact area between the wall 10 and the air becomes large, and the heat of the air is effectively transferred to the wall 10, so that the wall 10 can be heated more effectively.

The sauna box constructed as described above operates as follows. That is, when the heater body 16 of the heater device 15 is energized, the heater body 16 is heated, and part of the heat works to warm the human body by radiation, reflection, and convection as in the conventional case, but the remaining heat The heat in the space 19 at the back of the heater, which conventionally had no escape and was dangerous due to its high temperature, was transferred to the wall 1.
It flows into the space 12 inside the sauna box, heats the wall 10, heats the ceramic layer 14 coated on the inner surface of the wall 10, emits far infrared rays from all surfaces of the inner surface of the sauna box, and hits the human body from all directions. It will heat up evenly.

Therefore, when using the sauna box according to the present invention, the human body is heated more evenly than in the past, making it possible to enjoy a comfortable and safe sauna. The heat in the space behind the heater can also be released to prevent it from becoming too high, and there is no risk of fire or the like, and an extremely safe sauna box can be provided. Note that if fins or the like are provided on the back side of the wall, the above effect will be further promoted.
