DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sauna using far-infrared rays, which makes it possible to perform sweating in a comfortable state for a long period of time without feeling the pain of high heat and high dryness by fully utilizing the indoor space. An apparatus is provided.

[0002]

2. Description of the Related Art A sauna device has the following features. (1) A floor is provided with a floor in a room so that many people can use it at the same time.
One that uses air as a heat medium, (2) a chaise longue provided inside a housing that can be used by one or several people, and a heating device installed inside this chair or on the wall, and (3) an apartment Radiates radiant heat to the front by partitioning the washroom in a unit bath installed in a building or a bathroom installed in a general house, and also emits hot air from the feet to heat the human body with both hot air and radiant heat. There has been proposed an apparatus for performing the above.

[0003]

The present invention relates to an improvement of the above-mentioned device (1), and the disadvantages of this device will be described. In the device of (1), a heating device is provided in a corner of a large room, a lower portion of a chair or in a wall, and air in the room is reduced to 80 mm.
The temperature is maintained at a high temperature of about 110 ° C. to 110 ° C., and the atmosphere is dry, and chairs, floors, and snowboards are extremely hot. Therefore, the user receives a shocking thermal shock when entering the room, and in a warm bath, a battle between high temperature and high drying occurs.
It can only be used for about 0 minutes.

[0004] Since it is necessary to take a bath while being exposed to a severe atmosphere as described above, it cannot be used for people who are unwell, who cannot withstand high temperatures, and children who are sensitive to high temperatures. Also, the problem with this conventional device is that the user is exposed to extremely high temperatures for a very short period of time, so that it is not possible to sweat sufficiently, and the heating device is placed under the chair or in the wall. Care must be taken not to burn this chair or wall when the bath is warmed.

The present invention makes it possible to use the sauna room widely, reduce the air temperature as much as possible to directly transfer radiant heat to the human body, and transfer a large amount of thermal energy to the human body for a long time use. It is another object of the present invention to provide a device capable of promoting a large amount of perspiration as compared with a conventional sauna device.

[0006]

In a sauna apparatus according to the present invention, a heating device is provided on a ceiling portion of a sauna room having a stair-like chair portion, the heating device being directed to a floor surface. And a duct portion formed on the back surface of the heat radiation plate,
The heat radiation plate has a heating element disposed in the duct portion, the heat radiation plate has a porous ceramic layer formed by plasma spraying ceramic on the surface of a metal plate, and the duct portion has one end of the heat radiation plate. It is configured so that air is sucked and heated while passing through the heating element, and is ejected from the other end.

The metal plate constituting the heat radiating plate has a porous ceramic layer formed by plasma spraying ceramic on the surface, and preferably has a black processing layer formed on the back surface, so that far infrared rays can be efficiently emitted. It has the function of radiating light. In particular, the present invention does not apply heat to the human body mainly from the floor surface or chair portion and further from the wall surface as in the conventional sauna device, but directly or indirectly applies a metal plate having a porous ceramic layer formed as a heat source. The first feature is that a flat heating device that emits far-infrared rays from the surface of the ceramic layer by heating is installed on the ceiling surface.

In addition, a duct is formed on the back surface of the flat heating device, and the air in the sauna room is sucked from one of the ducts, and is blown out from the other or from the middle. This is to avoid raising the temperature of the air in the sauna room more than necessary,
While warming the body gently with this heated air, the body is sufficiently heated to the deep part of the body by far infrared rays radiated through the ceramic layer, causing a large thermal stimulus to the human body like a conventional device. It is configured not to give.

The position of suction and discharge of air in the room is determined by the size of each sauna room, the flow state of the air, and the position of the user. The temperature of the air in the sauna room is averaged as much as possible. It is better to set it so as to slightly rise at the position of the user.

[0010]

[Operation] Since a far-infrared ray is radiated from a planar heating device provided on the ceiling, it can be heated by projecting heat rays to the deep part of the human body. Furthermore, the heating device arranges a heat source for heating the heat radiating plate in the duct portion or on the heat radiating plate, and heats the air while the air passes through the duct portion and injects it into the floor of the sauna room. Therefore, this air is heated to a temperature of about 40 to 60 ° C. in this duct, not to a remarkably high temperature, and to a temperature that does not adversely affect the human body. Therefore, since the body can be heated from both the airflow and the far-infrared rays, it is possible to comfortably encourage a large amount of sweat without being tired even if the bath is warmed for a long time.
