Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention particularly relates to a sauna bath device for home use, and particularly to a low-temperature type sauna bath device.

(b) Prior Art Conventionally, this type of sauna bath device uses an electric heater as a heat source as disclosed in Japanese Utility Model Publication No. 58-20258, etc., and is visible even during use in the sauna room, making it visually unsightly. It was frightening and there was a risk of burns or electric shock. Furthermore, such a structure also has the disadvantage of localized heating.

(c) Purpose of the invention In view of the above points, the present invention provides a system that can be used with peace of mind.
Another object of the present invention is to provide a sauna bath device that can uniformly heat the inside of a sauna room.

B) Structure of the Invention For this purpose, the present invention forms a box-shaped sauna room using a panel etc. in which a heating element is embedded, and a wall surface facing the sauna room of the panel in which the heating element is embedded has a good thermal conductivity. The wall is made of a suitable material, and a surface material that emits far-infrared rays, which is a wavelength that is well absorbed by the human body, is adhered to the wall surface.

(e) Examples An embodiment of the present invention will be described in detail below based on the drawings.

First of all, the sauna bath device (1) has a hexahedral rectangular parallelepiped shape, with panels on both sides (2) (3), a front panel (4), and a back panel (5).
), a ceiling panel (6) and a floor panel (7),
A sauna room (8) above the floor panel (7) and a piping room (9) below formed by these panels are formed.

A doorway (10) is provided in the front panel (4), and the doorway is provided with a door body α1) that can be opened and closed. In addition, a chair (14) is provided at the rear part on the floor panel (7).
It is designed for the convenience of users.

Next, the structures of the both side panels (2+ (3), back panel (5), and floor panel (7) will be described. Since all the panels have the same structure, the back panel (5) will be described as an example.

First, the inner surface of the inner wall surface (5A), which has an open outer surface and has a box-like shape and is made of a material with good thermal conductivity, such as a steel plate, is heated at 80°C.
Heat exchange pipe made of copper pipe through which hot water passes before and after Q3)
The pipe α3 is bent from the upper surface in a meandering manner.
) is fixed with aluminum tape Q→ which increases the heat conduction area.

Both ends of the pipe (13) are connected to the inner wall surface (5).
Notches (15) provided at both corners of the lower end of A) lead out to α9. After this, the outer wall surface (5B) is replaced with the inner wall surface (5A).
and fix them together, then both walls (5A) (5B
) is filled with hard urethane foam to form a heat insulating material (I6).

The back panel (5) is formed in this way, but the side panels (21 (3)) and the floor panel (7) are also formed by foaming urethane on-site with the heat exchange pipe (131) installed. The insulation material αe is filled, but the floor panel (the sword has notches 0!19α group at both rear corners, and the notches (15)
The heat exchange pipe (13) is led out to α■. In this embodiment, the ceiling panel (6) and the front panel (4) are not provided with heat exchange pipes (13), but are filled with a heat insulating material.

(17) is connected to the boiler (21) and the boiler (2
The outgoing pipe that sends the hot water heated by 1) to the sauna bath device (1) communicates with the header outlet provided in the piping chamber (9) formed by each panel. ) (3), is connected to one end of each heat exchange pipe (13) in the back panel (5) and floor panel (7). The other end of each heat exchange pipe (0.3) is also connected to the piping chamber (
9) is connected to the boiler (21) through a header and a return pipe (201) provided in the sauna bath device (1), and the heat-exchanged hot water returns to the boiler (21) and is heated again and supplied to the sauna bath device (1). and is configured to circulate.

Then, each panel, that is, the inner wall surface (5A) of both side panels (2), (3), front panel (4), back panel (5), ceiling panel (6), and floor panel (7), has wavelengths that are well absorbed by the human body. A surface material that emits far infrared rays (the two are glued together).

This far infrared ray generally refers to electromagnetic waves with a wavelength of 3 to 1000μ, but when a polyvinyl chloride sheet is used as the surface material (22), far infrared rays of 7 to 10.2μ are emitted, and far infrared rays are emitted. When a cloth sheet (cotton, linen, etc.) is used, it emits far infrared rays of 3 to 12 microns, and the far infrared emissivity is about 90%.

It is said that the range in which the human body has good infrared absorption is 6 to 7μ and around 20μ, and the above-mentioned polyvinyl chloride sheet and cloth sheet are within this range and are fully suitable for the purpose. Furthermore, even if it comes into direct contact with each panel, it will not cause burns due to the surface material (22), so it can be said that it is an extremely good material as a surface material (22).

Of course, the front panel (4) does not have the heat exchange pipe (13) buried.
The surface material (2) does not necessarily need to be glued to the floor panel (7), but it is better to do so in consideration of the harmony within the sauna room (8).

The heat exchange pipes embedded in each panel are configured to circulate hot water, but are not limited to this and may be heaters. At this time, the insulation material is preferably glass wool or the like.

Because of this configuration, hot water heated by the boiler (21) first passes through the outgoing pipe 07) and the header α8) to the side panels (2), (3), the back panel (5), and the floor panel (7). The heat passes through the buried heat exchange pipe α (8) and is radiated from the inner wall surface of each panel toward the sauna room (8). At this time, hot water of around 80°C circulates inside the heat exchange pipe (13), and for example, when a polyvinyl chloride sheet is glued as a surface material (2 layers), the surface material (2 layers)
2) is heated to generate electromagnetic waves with a specific wavelength, i.e. 7 to 10.2
Emit far infrared rays of μ. Therefore, it stimulates the thermal zone of the user sitting on the chair <12) in the sauna room (8), and a sufficient sweating effect can be obtained even if the temperature in the sauna room (8) is relatively low. Of course, even if you touch the inner surface of the panel during use, it will not cause burns because the temperature is lower than when the inner wall surface (5A) is exposed due to the surface material @.

The heat-exchanged hot water in each pipe (13) passes through the header and return pipe (20) in the piping room (9) to the boiler CI! ]).
