Description

[Detailed description of the invention] [Industrial application field] This invention heats the air inside the sauna bath room using a heat source such as an electric heater, raises the room temperature to around 100℃, and at the same time generates sweating using far infrared rays. This invention relates to an improvement in an air heating device for sauna baths that has an accelerating effect.

[Prior art and its problems] There are several types of sauna baths. As mentioned above, the air inside the sauna bath room is heated with an electric heater to raise the room temperature to around 100℃,
Conventionally, air heating devices for sauna baths that provide thermal stimulation to bathers in a low-humidity atmosphere to promote sweating have generally been of an electric stove structure using an electric heater. This kind of thing is installed in the corner of the sauna bath room,
Water is poured onto stones placed on a heating plate that is heated by an electric heater to generate steam, thereby achieving an appropriate level of humidity. Therefore, this type of heating device having a stove structure takes a long time to start up and start up, depending on the volume of the sauna bath. One of the reasons is that
Since indoor air is only heated through an electric heater, forced circulation of indoor air is not possible, and there is no heating effect using radiant heat.

The purpose of this invention is to improve such an electric stove-type heating device, and to make use of the draft effect created by the rising air flow inside the cylinder, to make the heated air uniform in the sauna bath room, to use the radiant heat from the cylinder, and to use it from a distance. Effectively promotes sweating in bathers through the radiation effect of infrared rays,
Furthermore, it is an object of the present invention to provide an air heating device that can be started up in a short time after starting, and can also be used effectively with conventional stove-type heating devices.

[Means for Solving the Problems] The structure of the present invention, which solves the problems of the prior art, is that an electric heater is installed in the lower part of the inside of an elongated vertical cylinder whose entire area is coated with a far-infrared emitting coating mainly made of ceramic. At the same time, leg members are provided at the lower end of the cylindrical body to form a ventilation gap for a draft effect to constitute the heating element A. , and a shallow casing made of stainless steel or the like with an open front is provided, a plurality of the heating bodies A are arranged in parallel at appropriate intervals within this casing, and a cylindrical body constituting the heating bodies A is provided. The upper end is opened close to an eave formed at the upper end of the housing end and inclined upward toward the opening direction of the housing, and each of the cylinders is located close to the front surface of the vertical wall of the housing. It is characterized by this.

[Embodiment] Next, details of an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view, FIG. 2 is a partially cutaway side view of the same as the above, and FIG. 3 is a functional explanatory diagram.

Reference numeral 1 in FIG. 1 denotes an elongated vertical cylinder whose outer surface or the entire inner and outer surfaces are coated with a far-infrared emitting coating (not shown) mainly made of ceramic, for example, and the inner lower part of the cylinder 1. A heating element 2 such as an electric heater is provided in a circuit that heats the cylindrical body 1 and has a temperature sensing element (not shown). The heating body A is constructed by providing leg members 5 at the lower end of the cylindrical body 1 to form a ventilation gap 4 for a draft effect.

Reference numeral 6 denotes a shallow casing made of a material such as stainless steel with an opening on the front side. Inside the casing 6, a large number of heating elements A having the above structure are arranged in parallel, and the upper end of each cylindrical body 1 is An opening is formed near the eaves 6a formed at the upper end of the casing 6 and inclined upward toward the opening direction of the casing 6, so that the heated air jetted out from the upper end of each cylinder 1 is directed to the casing 6. The eaves 6a of the casing 6 direct water to the upper part of the sauna bathroom, and the reflected heat from the inner surface of the vertical wall of the casing 6 is also added.

[Description of operation] The operation will be explained based on the above embodiment. This device is installed along one side wall of a sauna bathroom as shown in FIG.

First, upon starting, the heating element 2 such as an electric heater is turned on and energized to heat each cylindrical body 1. Each cylinder 1
When heated to a single volume, the heated air in each cylinder 1 is released into the sauna bath room from the upper end opening of the cylinder 1 as an upward airflow, and a large amount of far-infrared rays is emitted from the surface of each cylinder 1. . The cold air in the sauna bath room is sucked into the cylinder 1 through the ventilation gap 4 formed at the lower end of the cylinder 1, that is, by the draft effect, and the heated air heated by the heating element 2 is transferred to the sauna. The sauna room is filled with air, and the air in the sauna room rises quickly, making it possible to take a bath in a short time. Then, when the room temperature reaches a set upper limit temperature, for example, 100° C., a temperature sensing element (not shown) provided in the electric heater circuit shuts off the electric heater circuit, and the heating action is interrupted. When the room temperature reaches the set lower limit temperature, for example 90° C., due to this heating interruption, the electric heater circuit is turned on again and the air in the sauna bath room is heated.

Figure 3 shows the flow of air in the sauna bath room, where the arrow a indicates a semi-forced circulating heated air flow, the arrow b indicates an air flow accompanying the circulating heated air,
The c arrow indicates far infrared radiation, the d arrow indicates reflected far infrared rays, and the e arrow indicates circulation flow into the ventilation gap 4. In addition, far infrared rays are spread widely as indicated by the arrow c above, and can be seen not only on the side walls of the sauna bathroom, but also on the ceiling,
It heats the floor and chairs, and by repeatedly reflecting far-infrared rays, it can warm even the water droplets in the sauna bath room.

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Air inside the sauna bath heated by the electric heater is discharged from the top of each cylindrical body, guided by the slope of the eaves of the housing, and efficiently discharged into the sauna bath, This circulating heated airflow causes the air in the room to flow, speeding up the heating, and furthermore, radiant conduction heat and far infrared rays from the heat source and the cylinder heated by the heated air are also added, and the above-mentioned third As explained in the figure, heating of the room to the set temperature can be done in a short time.

(b) Since the depth of the casing is shallow and each cylindrical body is close to the inner surface of the vertical wall of the casing, the far infrared rays emitted from the cylindrical bodies are reflected by the inner surface of the vertical wall, and the reflected far infrared rays of can be added to indoor heating, and furthermore, the bathing time can be accelerated and bathing efficiency can be improved.

(c) It is possible to configure an appropriate temperature sauna bathroom by increasing or decreasing the number of heating elements A depending on the size of the sauna bathroom or the setting conditions of the upper limit heating temperature.

(d) A conventional electric stove-type air heating device can be used as a heat source, simplifying the device and significantly reducing costs.
