Description

[Detailed description of the invention] [Technical field] This invention relates to a sauna that prevents internal heat from leaking.

[Background technology]

A small sauna for home use is equipped with a heating device such as a stove inside the room, and the space inside the sauna is heated by this stove. Stoves are usually equipped with an electric heater and use natural convection to heat the room.

After heating begins, natural convection saunas like this
The problem was that it took a long time to reach the set temperature. For example, it took more than 30 minutes to heat the sauna room to 80℃.

One of the reasons for this is that heat escapes through the door gap at the sauna entrance/exit opening.

[Purpose of invention]

This invention was made in order to solve such problems, and the purpose is to provide a sauna with less indoor heat leakage and a short heating time.

[Disclosure of invention]

In order to achieve the above-mentioned purpose, this invention is based on a sauna in which a door is rotatably attached to the entrance, so that the end surface of the door on the hanging side becomes closer to the end surface of the entrance and exit opening as it goes into the sauna. The gist of the sauna is that it is slanted to widen the gap between the saunas.

This invention will be explained below along with drawings showing one embodiment thereof.

FIG. 2 shows an embodiment of the sauna according to this invention. In this sauna 1, the walls 2 are covered with a slatted interior material 3, and the room is heated by a heater 4 for bathing. A door 5 serving as an entrance into the sauna room is rotatably attached to the sauna body with a hinge. As shown in FIG. 1, the door 5 has a gap C between the end surface 5a of the hanging source side and the end surface of the doorway opening (door frame) as it moves toward the room A.
It is sloped so that it becomes wider. Door stops 7, 7 are formed in the entrance/exit opening of the sauna wall.

A conventional sauna door 15 has a shape as shown in FIG. 3, and is designed to abut against doorstops 7, 7 on the inside of both sides to maintain airtightness within the sauna room. However, saunas have large temperature fluctuations, which causes the door material to change dimensions and become thinner, as shown in door 15' indicated by the dashed line.As a result, door 15' and doorstop shrink. In some cases, a gap D was created between the two. However, as in the above embodiment, if the end surface 5a on the hanging side of the door is inclined toward the room, even if the door contracts, the end surface on the hand side will be tilted toward the room, as shown in FIG. Since the sauna can be rotated until it comes into contact with the abutment 7, the gap D is eliminated and heat is prevented from escaping from the sauna room.

Conventionally, due to the thickness of the door itself, there was a gap E between the end surface of the sauna entrance/exit opening and the end surface on the hand side of the door.
The door could not be rotated unless it was opened. As a result, heat sometimes escaped from this part. However, as in the above embodiment, if the door end face 5b is inclined so as to widen the gap B between it and the end face of the doorway opening toward the sauna room, heat escape can still be prevented. be done. 6 is a hinge.

The sauna according to this invention is not limited to the above embodiment.

Generally, the interior of a sauna is lined with a slatted interior material. Each slatted board is connected with crosspieces at intervals of approximately 8mm. The wall structure of such a sauna is shown in Fig. 5, in which a noncombustible material 12b made of Keikal board or the like is pasted as a base material on the inside of an exterior material 12a made of decorative plywood, etc. A slatted interior material 13 consisting of is arranged. As a result, the heat inside the room comes into direct contact with the wall through the gaps between the slatted boards, travels along the wall, and escapes to the outside, making it impossible to increase the rate of temperature rise inside the sauna, and furthermore, the thermal efficiency is low, resulting in high power consumption. It was a disadvantage. However, in a sauna having a wall structure as shown in FIG. 6, it is difficult for the heat inside the room to escape to the outside, and the temperature inside the sauna can be raised efficiently. This sauna uses an interior material 14 with no gaps between slatted boards. This way, the hot air inside the room will not be transmitted to the walls through the gaps and escape to the outside. Moreover,
The air layer 10 formed between the wall surface and the interior material is
This results in a heat insulating effect, further shortening the temperature rise time.

[Effect of idea]

Since the sauna according to this invention is constructed as described above, there is little heat loss, the temperature rise time can be shortened, and it is economical.
