Description

DETAILED DESCRIPTION OF THE INVENTION [Subject of the Invention] The present invention relates to the improvement of electric sauna baths, and in particular, in an electric sauna bath having a panel heater, it is possible to effectively utilize the heat trapped in the back of the heater (- This invention relates to an electric sauna bath with a fan that circulates water.

[Background of the invention]

In recent years, electric sauna baths, especially electric sauna baths using far-infrared heaters, are said to be good for health and beauty, and have been developed not only for commercial use but also for general home use and have gained popularity.

FIG. 1 is a side cross-sectional view of an electric sauna bath having a conventional panel-shaped sauna bath. As shown in FIG. It allows warm air to circulate.

However, in the case of an electric sauna bath having a panel-shaped heater 4 as described in item 1 (2), a large amount of heat will be trapped between the back of the heater 4 and the inner wall of the sauna bath main body 1, as described above. If the fan 2 is simply installed at an appropriate position inside the sauna bath body, the heat trapped between the back of the heater 4 and the inner wall of the sauna bath body l cannot be used effectively, resulting in poor thermal efficiency. In addition, in a sauna bath having the structure as described above, the temperature of the floor of the sauna bath inevitably becomes low, making the bathers feel cold and uncomfortable.

[Purpose of the invention]

The present invention was made in view of two series of point C2, and an electric sauna bath C2 having a pile-shaped heater,
The back of the heater (2) makes use of the accumulated heat (1) to improve thermal efficiency, and also sends warm air to the feet of the bather, providing a comfortable electric sauna bath with fan that allows bathers to enjoy a bath for two. The purpose is to

[Summary of the invention]

The gist of the present invention is that a panel-shaped heater is provided with a predetermined gap from the wall surface of the sauna bath main body (-1), and a fan is provided at the bottom of this gap, and the heat emitted from the back of the heater is radiated into the gap. The heated air is circulated from the bottom of the sauna bath body by the fan, and the heat accumulated on the back of the heater is effectively used. Comfortable without feeling your feet get cold (There are two electric sauna baths that can be enjoyed by two people).

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a side sectional view, not showing, of an electric sauna bath with a fan, which constitutes one embodiment of the present invention. Referring to FIG. 2, parts with the same reference numerals as those in FIG. 1 indicate the same or equivalent parts (hereinafter, the same applies to other drawings). The pile-shaped heater 4 is attached to the sauna bath main body 1 by a suitable attachment member 5c2 with a gap g provided from the inner wall surface.

At the bottom of the gap g formed between the heater 4 and the inner wall surface of the sauna bath 1, a long fan 6 is provided parallel to the bottom surface of the heater 4.

In the structure as described in item 1, when the fan 6 is started, the air in the sauna bath main body l enters from the upper part of the gap g, and the heat emitted from the back of the heater 4 (2) descends while being warmed, and is heated by the Noan 6. It is sent to the bather's feet 8. In this case, if the fan 6 is placed parallel to the floor of the sauna bath main body 1, the warm air sent from the fan 6 will be immediately blown onto the floor and will be sent to the bather's feet 8. It may not reach you.

Therefore, by adjusting the bevel angle α at an appropriate angle, even greater effects can be obtained. This value is related to the size of the sauna bath and the width of the seat 9, but it has been experimentally confirmed that it is best to set it at about 15 degrees.

When the warm air directly hits the feet 8 of the bather 3, the bather 3 does not feel that his feet are cold as in the past, and can enjoy a comfortable bath.

3 and 4 are views showing a heater unit in which the pile heater 4 and the fan 6 are integrally formed, and FIG. 3 is a front view, and FIG. be. In the figure, IO is a heater frame formed by pressing a metal plate, etc., and a large number of metal rods 1 formed in a grid shape are provided on the front of this frame 10. A gap g is provided between the back surface of the pile-shaped heater 4 and the inner surface of the heater frame 10.
The upper heater is attached to the heater frame O on the side of the appropriate attachment part.

At the bottom of the gap g, a long fan 6 whose length is slightly shorter than the width of the heater 4 is attached to the heater frame with an appropriate mounting system (2). In such a configuration, when the heater frame 10 is activated, the air inside the sauna bath body enters from the front of the heater frame 10 (7, heater 4
The fan passes through the gap between the upper part of the heater frame 10 and the upper inner surface of the heater frame lO, and then passes through the gap g between the back surface of the heater 4 and the back inner surface of the heater frame ]-0, and is warmed by the heat emitted from the back surface of the heater 4. Reach 6. Warm air is sent from the fan 6 to the feet of the bather, and the air in the sauna bath body is circulated.

-3 By integrating the heater 4 and fan 6 into the heater frame and making it a part of the sauna bath, it can be easily attached to the sauna bath body using simple mounting materials.
It can be installed twice, making repairs and other maintenance extremely easy.

In the above embodiments, the panel-shaped heater may be of any type, such as a far-infrared pile heater, or a plurality of sheathed heaters arranged in parallel to form a flat panel. In addition, even though it is called a panel shape, it is not limited to a flat surface, but may also be wavy or the like.
It is good to have a heater that is shaped to trap heat.

In addition, in the above embodiment, a long fan was used as the shape of the fan. If so, a round fan is fine.

〔Effect of the invention〕

As explained above, in the electric sauna bath with a fan according to the present invention, the fan is installed at the lower part of the gap between the panel heater and the wall surface of the sauna bath body or the frame of the heater. By effectively utilizing (1) and improving thermal efficiency, (2) hot air directly hits the feet of the bather, which has the extremely excellent effect of allowing the bather to enjoy bathing comfortably.
