Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In a conventional general sauna heater, an electric heater is used as its heat source. However, the electric heater has a risk of electric shock due to electric leakage, and the energy cost itself is high, resulting in a very high running cost. Since it is expensive, recently, instead of this, for example
As seen in Japanese Patent Laid-Open No. 922 and Japanese Patent Laid-Open No. 60-168455, a gas heater of a sauna heater using far infrared radiation heat as a heat source is widely used.

[0003]

However, in the conventional far-infrared radiation type sauna heater, the heat radiating portion is constructed as a panel or the heat radiation tube is simply bent up and down repeatedly. All of them have a meandering piping structure, both of which are original Scandinavian-type saunas that use the high-temperature steam heat generated by putting stones that have been baked at high temperature for a long time in a container and applying water to them. It is quite different from the heat source (stove), and there was a problem that it was not practical for a sauna.

Further, the conventional far infrared radiation type sauna heater uses the dry convection heat and radiant heat of far infrared radiation radiated from the panel plate or the heat radiation tube as a heat source.
It has been recognized that there is a definite difference in the presence or absence of humidity from the above-mentioned original heat source for saunas that uses steam heat.

Therefore, a technical object of the present invention is to provide a sauna heater device having a high heat efficiency and a structure close to the original heat source for a sauna of the Nordic type which can utilize steam heat and an excellent heat dissipation function. Is to provide.

[0006]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows.

By far-infrared radiant heat and convective heat radiated from the heat-radiating tube for combustion gas piped in the sauna room,
A sauna heater device configured to heat the inside of a sauna room,

[0008] (1) to hem the heat radiation tube is a pipe formed in a substantially pyramidal or conical coiled widen gradually
Thus the structure and heat radiation unit, placed on the casing inside the top open, upper end side upright combustion cylinder in communication with said heat radiating pipe to the inside of the heat radiating portion, and, on the heat radiating portion A large number of sauna soots are loaded and water is sprinkled on them to install a heater unit configured to generate high temperature radiant heat and steam heat in the sauna room, while a burner is installed in the combustion cylinder in this heater unit. Install.

(2) An air duct is provided between the heater unit installed in the sauna room and a partition wall that separates the sauna room and the machine room, and a fuel supply pipe for a burner is provided inside the air duct. In addition to piping, provide the burner combustion adjustment section inside either the heater unit or the air duct. (Claim 2)

[0010] (3) to hem the heat radiation tube is a pipe formed in a substantially pyramidal or conical coiled widen gradually
The thus configured heat radiation section, while mounted on the casing inside the top open, upper end inside of the heat radiating portion is erected combustion cylinder in communication with the heat radiating tube above and, on the heat radiating portion by multiplying the number of sauna stone which in water loaded with, the configuration and heater units to generate high-temperature radiant heat and steam heat installed in the sauna room co to

State, that is, the heater unit can be freely installed and used at any position in the sauna room, the gas pipe is connected to the inside of the air duct, and the combustion adjusting section of the burner is connected to the air duct. Alternatively, since it can be provided inside either of the heater units, a bather can safely take a sauna bath.

According to the third aspect of the invention described in (3) above, since the burner is provided in the sauna room,
As mentioned above (1), the thermal efficiency can be improved compared to the case where it is installed in the machine room, and the structure of the sauna room can be simplified because it is not necessary to take various heat resistance measures on the partition wall. In addition to exhibiting the same effect as that of the above, the heat dissipation part of the heater unit is composed of the combustion cylinder and the heat radiation pipe , and the discharge including the top part of this combustion cylinder.
Since sauna stones are loaded on the heat section , the sauna stones can be efficiently heated to generate high-temperature radiant heat and steam heat, and it is also possible to enhance the heat dissipation effect by natural convection. To do.

In addition, according to the third aspect of the invention described in (3) above, since the air duct can be provided between the partition wall and the heater unit, the heater unit can be separated from the partition wall. That is, the heater unit can be freely installed and used at any position in the sauna room.

As described above, the above (1)-
By solving the above-mentioned technical problem by the means of (3),
It is possible to solve the problems of the conventional technology.
