DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater (stove) for a sauna suitable for use in various types of sauna rooms for home and business use.

[0002]

2. Description of the Related Art A conventional general heater for a sauna uses an electric heater as a heat source, but the electric heater has a risk of electric shock due to electric leakage, and the energy cost itself is expensive and the running cost is very high. In recent years, instead of this, for example,
As disclosed in Japanese Patent Application Publication No. 922 and Japanese Patent Application Laid-Open No. 60-168455, sauna heaters using far-infrared radiation heat of a gas combustion type as a heat source are often used.

[0003]

However, in the above-mentioned conventional far-infrared radiation type heater for a sauna, the entire heat radiating portion is formed in a panel type, or the heat radiation tube is simply bent up and down repeatedly. Each of these is a meandering plumbing structure, all of which are stones baked at a high temperature for a long time in a container, and the original Nordic type sauna that uses the high-temperature steam heat generated by applying water to it. The heat source (stove) is quite different from the heat source, and there is a problem of lack of practicality for a sauna.

Further, the conventional far-infrared radiation sauna heater uses far-infrared dry convection heat and radiation heat radiated from a panel plate or a heat radiation tube as heat sources.
It was recognized that there was a decisive difference in the presence or absence of humidity from the original sauna heat source using the above-described steam heat.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a structure similar to a Scandinavian type original heat source for a sauna, which can utilize steam heat, and a sauna heater having an excellent heat radiation function.

[0006]

Means taken by the present invention to solve the above-mentioned technical problems are as follows.

A sauna heater configured to heat the inside of a sauna room by radiant heat of far-infrared rays radiated from a heat radiating tube of combustion gas piped in the sauna room,

(1) The above-mentioned heat radiation tube is repeatedly bent in a plane direction and in an upward and downward direction to gradually widen the skirt.
While constituting a heat radiating portion formed in a substantially pyramidal or conical coil shape, the heat radiating portion is placed inside a casing having an open-top, heat-resistant and water-resistant structure, and a large number of heat radiating portions are placed on the heat radiating portion. sauna Stone was loaded with, this, such as sauna Storr of
Be constructed so that water is applied from above . (Claim 1)

[0009] (2) a portion of the heat radiating tube, to extend the pipe to the lower interior of the installed bathers bench in sauna room. (Claim 4)

According to the means of claim 1 described in the above (1), the heat radiating portion formed by bending the heat radiating tube into various shapes is installed inside a casing having a heat-resistant and water-resistant structure. It is a structure in which sauna stones are loaded. In order to burn and heat the sauna stones loaded with far-infrared radiation heat radiated from the radiator, the sauna room is uniformly and softly radiated by the sauna stones. Because it can be radiated, you can expect the same effect as the original Nordic sauna stove that uses the baked stone as a heat source.
By applying water to this sauna stone heated by the heat radiation tube, it is possible to generate high-temperature steam heat,
It enables comfortable and body-friendly sauna bathing by radiant heat of far infrared rays containing appropriate humidity.

Furthermore, according to the means according to claim 1 described in the above (1), the overall heat radiation tube for radiating far infrared rays, are pipes formed in a substantially pyramidal or conical coiled spread the hem gradually Therefore, by installing this inside the sauna room and loading sauna stones, it gives the bather a wild and natural impression that the heat source is just piled in a pyramid shape inside the sauna room. Therefore, compared with the conventional panel heater or sauna heater having a meandering pipe structure, it is possible to give a good impression close to the original sauna heat source of the Nordic type, and to make the heat radiation tube a substantially pyramidal or conical shape. As a result of piping in the shape of a coil, it is possible to compactly install a long-length heat radiation tube inside the narrow sauna room,
High thermal efficiency enables high-temperature, comfortable sauna baths.

[0012] The According to the measure according to claim 2 as described in (2), bather to set up a part of the heat radiation tube into the sauna room
By extending the piping inside the lower part of the bench for heat dissipation, the temperature distribution inside the sauna room is made uniform, and the bather's lower limb
