Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to a stove for a sauna room.

[Background Art] The inside of a sauna room is heated to, for example, around 80 to 100°C. For this reason, water is often sprinkled to bring the humidity inside the sauna to an appropriate level. This watering is done on the stove for the sauna room,
If water splashes on the heating element (heater), it may be damaged or become unable to heat up. If the heating element uses electrical energy, it may be dangerous to shoot.

[Purpose of invention]

In view of the above, the purpose of this invention is to provide a stove for a sauna room that has good heat distribution and does not cause trouble even when water is sprinkled on it.

[Disclosure of invention]

In order to achieve the above object, as shown in FIG. 3, a sauna room stove 24 was devised in which a heating element 21 is covered with an inner box 22 up to its lower part, and the surrounding area is further covered with an outer box 23. Water is in the inner box 22
Flows on the surface as shown by arrow 25. However, in this sauna room stove 24, the heating element 21 is completely covered up to its lower part with the inner box 22, so the air heated by the heating element 21 once descends and flows as shown by the arrow 26. Therefore, there is a problem that the convection of hot air is insufficient and the heat distribution is not good.

In this invention, in order to solve this problem and achieve the above-mentioned purpose, the heating element is covered to the bottom with a hood, and water can be sprayed onto the ceiling of the hood. The stove for a sauna room is provided with a passage on the ceiling of the hood that guides the gas heated by the heating element to the outside of the hood, and the ceiling of the hood is parallel and slopes as this passage. Consists of two partition plates that
The space formed between these opens into the hood at a high point on the lower partition plate, and
The gist is a stove for a sauna room, which is characterized by an opening to the outside of the hood at the lower part of the upper partition plate.

This invention will be explained in detail below based on drawings showing examples thereof.

FIG. 1 shows one embodiment of this invention, and FIG. 2 shows a schematic view of this installed in a sauna room.

As shown in FIG. 2, this sauna room stove 1 is installed inside a sauna 2 and heats the inside of a sauna room 3.

As shown in FIG. 1, in this sauna room stove 1, a heating element (also referred to as a "heater") 4 is covered with a hood 5 up to its lower part. The ceiling portion of the hood 5 is composed of two partition plates 6 and 7 that are inclined in parallel. A space 8 formed between these partition plates 6 and 7 opens into the hood 5 at a high point of the lower partition plate 7, and opens to the outside of the hood 5 at a low point. For this reason, space 8
is a passageway that allows gas (usually air) heated by the heating element 4 to pass through, but does not allow the water applied to the ceiling of the hood 5 to pass through. This is because the opening of the space 8 into the hood 5 is located higher than the opening to the outside of the hood 5.

The air heated by the heating element 4 rises inside the hood 5 and exits the hood 5 through the passage (arrow 9).

In this way, in the sauna room stove according to this invention, the heated gas does not descend as much as shown in Figure 3 (arrow 26), the heat distribution is improved, and sufficient convection occurs. . Therefore, the inside of the sauna room 3 can be heated quickly and efficiently.

When water is sprinkled on the ceiling of this sauna room stove 1, the water falls along the outer surface of the hood 5 (arrow 10), is heated, and evaporates. In this manner, the sauna room stove according to this invention does not cause any trouble even when water is sprinkled on it, since the water does not come onto the heating element.

When the passage in the hood ceiling is structured as in this embodiment, water may fall from the upper end side of the upper partition plate 6 when water is sprinkled on the sauna room stove 1. If the heating element 4 uses electrical energy, the falling water will be connected to the wiring 1.
3, etc., may be applied to live parts and cause trouble. To prevent this, an upwardly extending wall 11 may be provided at the upper end of the upper partition plate to prevent water from falling therefrom.

When the above-mentioned passage in the hood ceiling is structured as in this embodiment, when water is sprinkled on the sauna room stove 1, the side where water falls (the lowered side of the hood ceiling) is Since the sauna is heated by the hood 5, the heated water may splash and cause burns to the sauna bather. If the sauna room stove 1 is provided with a wall 12 facing the side of the hood 5 on the side where the ceiling is lowered, this wall 12 will prevent heated water from scattering. this wall 12
may be supported by an arm-shaped member on the hood 5, or may be supported by a wall having the same height as the wall 11.

If the heating element uses electrical energy as in this embodiment, no harmful gas will be generated in the sauna room, but trouble may occur if live parts such as wiring get wet with water. Therefore, this can be prevented by covering the charging part with a hood together with the heating element. For live parts that are not covered by a hood, you can protect them from water as described above.

In the above example, the partition plates on the ceiling of the hood are double-layered, but the overlapping partition plates are alternately shifted from one side to the other, and the outermost plate is connected to the side of the hood without any gaps. , the openings into and out of the hood may form passageways in the manner described above.

Note that this invention is not limited to the above embodiment.

[Effect of idea]

Since the sauna room stove according to this invention has the above-described structure, it has good thermal efficiency and does not cause any trouble even when water is sprinkled on it.

〔reference〕

As shown in Figure 2, the sauna 2 heats gas (usually air) with a heating element (also referred to as a "heater", not shown) such as a sheathed heater of the sauna room stove 1, and then uses this hot air as it is. Sauna room 3
The interior of the sauna is heated by raising it to the top and causing natural convection. However, if the gas heated by the heating element is allowed to rise directly to the upper part of the sauna room, only the upper part H (near the ceiling) of the sauna room 3 will quickly heat up, while the lower part L (near the floor) will remain cold for a long time. This causes problems such as large temperature fluctuations in the sauna room and the feet of bathers getting cold.

By using a sauna room stove as shown below, temperature unevenness in the sauna room can be reduced.

For example, there is a sauna room stove 1 as shown in FIG.

As shown in FIG. 4, this sauna room stove 1 is provided with a reflecting plate 14 on the top of the heating element 4 to reflect the radiant heat from the heating element 4. This reflective plate 14 reflects the radiant heat from the heating element 4 to a relatively lower part of the sauna room 3, which, together with the natural convection of hot air, reduces the temperature unevenness in the sauna room and quickly The temperature inside the sauna increases. The heating element 4 is usually surrounded by a hood 15 to reduce radiant heat to the bather. The upper part of the heating element 4 was open, and the radiant heat and hot air came out toward the ceiling of the sauna room, causing temperature unevenness. By installing a reflector on the top of the heating element, we slightly change the flow of hot air and reflect the radiant heat.
Temperature unevenness disappeared and the rate of temperature rise became faster. Incidentally, the reflection plate 14 is often attached to the upper part of the hood 15, as shown in FIG. 5a. As shown in FIG. 5b, when the reflector 14 is attached to the middle and lower part of the hood 15, the angle of the reflector 14 can be easily changed, and the reflection destination can avoid the position of the bather's face. Further, as shown in FIG. 5c, if the reflecting plate 14 is a perforated reflecting plate 18 with through holes 16..., the holes 16...
Some of the hot air and radiant heat passes through and rises toward the ceiling, and some of it is reflected by the reflector 18, making it possible to further reduce temperature unevenness and heat the sauna room in a shorter time. It is.

Note that the shape and method of providing the reflector are not limited to these.
