Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foldable sauna device suitable primarily for home use.

Sauna baths are generally known to be effective for beauty and health, and small sauna baths for home use have also been proposed. The present inventor previously proposed a sauna device that uses a planar heating element as a heating means to heat the body efficiently by directly irradiating the body with radiant heat, but the present invention further improves this by making it foldable. When storing, chairs etc. are also stored together.
The purpose is to facilitate transportation and handling.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

1 to 10 show Example 1,
The sauna device A includes a surrounding wall 2 forming a heating chamber 1;
A frame member 3 and a chair 4 are provided to maintain the surrounding wall body 2 in a predetermined expanded shape.

The surrounding wall body 2 includes a spine part 5, left and right side parts 6, 7, a front part 8, and a heating chamber 1 surrounded by these parts.
It consists of a covering cloth 9 that covers the upper part of. The left and right sides of the spine portion 5 are bent forward to form left and right protrusions 5a and 5b, forming a storage portion 10 having a required thickness, which will be described later. In this case, the upper part of the spine part 5 may also be bent forward to form the upper protruding part 5c, but this is not necessarily necessary, and the upper protruding part 5e is omitted, and the cover 9 is used to cover the upper part of the storage part 10. may be covered.

The front part 8 is divided into left and right parts at the center to form left and right front parts 8a and 8b, respectively.
The divided portions a and 8b are connected by a removable connecting means 11, such as "Magic Tape" (trade name), which has mushroom-shaped protrusions that are engaged with each other.

In addition, the covering cloth 9 is similarly divided into left and right parts to form left and right covering cloths 9a and 9b, and a neck hole 12 is drilled above the divided part to expose the neck during use.
A removable connecting means 13 reaching 2 is connected, for example, by a fastener or the like. In this embodiment, the front part 8 and the covering cloth 9 are connected by separate connecting means 11 and 13, respectively.
The two may be connected by a connecting means 13 such as a fastener.

The spine portion 5 is constructed by covering a heat insulating member 15a and a planar heating element 16a attached to the inner surface of the heat insulating member with an inner cloth 17 and an outer cloth 18. In addition, the left and right side surfaces 6 and 7 are each divided into heat insulating members 15 that can be folded in the front and rear directions.
b, 15c, 15d, 15e, and a planar heating element 16 attached to the inner surface of each heat insulating member.
b, 16c and 16d, 16e are covered with an inner fabric 17 and an outer fabric 18 that are common to the spine part 5, and the boundary with the spine part 5, between each heat insulating member, and the boundary with the front part 8 are sewn 20. At least make it bendable. In addition, the front parts 8a and 8b are provided with heat insulating members 15f and 15g, respectively, using an inner cloth 17 common to each of the above-mentioned face parts.
It is covered with an outer cloth 18. In this case, each side surface portion 6, 7 is folded as shown in FIG.
Therefore, the width of each rear side surface portion 6a, 7a is 1/2 or less of the length of the spine central portion 5d, and the width of each front side surface portion 6b, 7b is are equal to or slightly shorter than the rear side portions 6a, 7a.

The inner cloth 17 and the outer cloth 18 are made of a waterproof material or a cloth treated with waterproofing, and the inner cloth 17 is preferably made of a raised cloth.

The above-mentioned heat insulating members 15a, 15b (hereinafter collectively referred to as simply 15) may be made of an appropriate heat insulating material such as a wooden board or a synthetic resin board, but preferably a hard urethane foam which is lightweight and has a good heat insulating effect. It is composed of plates.

Further, as the planar heating elements 16a, 16b... (hereinafter collectively referred to simply as 16), those having an appropriate well-known structure are used. For example, carbon powder alone or a mixture of carbon powder and a binder such as polyethylene powder is coated on a substrate of an electrically poor conductor and melted to form a resistive film with a desired electrical resistance, and then the entire length is covered. A conductive wire is attached to the wire, and a heat-resistant waterproof film made of an electrically poor conductor is coated on the surface. The temperature of this sheet heating element 16 is controlled by the temperature control device 3.
Controlled by 0. This temperature control device 30 mainly includes a triax 32 provided in a main circuit 31 connected to one lead wire of the planar heating element 16, and a heat-sensitive thyristor 34 provided in a trigger circuit 33 of the triax 32. , the heat-sensitive thyristor 34 includes a variable resistor 3 that arbitrarily sets the operating temperature.
5. The heat-sensitive thyristor 34 is attached to a suitable position on the planar heating element 16. As a result, when the planar heating element 16 reaches a predetermined temperature, the heat-sensitive thyristor 34 is operated and the triax 32 is cut off.

In the temperature control device 30 of this example, a bypass circuit 36 is provided in parallel with the triax 32. This bypass circuit 36 includes a half-wave rectifying element 37 such as a half-wave rectifying diode. After the triac 32 is cut off by this, an electric charge is applied to the planar heating element 16 via the bypass circuit 36. The bypass circuit 36 is only half-wave conductive, so the current is halved and the temperature drops slowly. However, even at this point, the planar heating element 16 maintains a considerably high temperature (a temperature higher than room temperature) due to the energization, and therefore far-infrared rays are continuously emitted.
In the figure, 38 is a safety temperature fuse, and 39 is a sub-temperature control member provided as necessary in the bypass circuit 36, which opens the circuit when the temperature rises even with the halved current in summer or the like. The thyristor 34 is made of a bimetal or the like that is opened at a higher temperature (for example, 90° C.) than the thyristor 34.

In FIG. 1, reference numeral 40 indicates an operation panel, and the operation panel 40 includes a power supply socket 41, an earth leakage breaker 42, and a dial 4 for operating the variable resistor 35.
3. An energizing lamp 44, a suitable temperature lamp 45, etc. are attached.

The covering cloth 9 preferably has a heat insulating effect, and for example, as shown in FIG. 5, an aluminum foil 51 is laminated as a reflective member on the inner surface of a heat insulating thin plate member 50 made of flexible synthetic resin such as foamed polyurethane or polyethylene. This is then covered with an inner cloth 52 and an outer cloth 53 which are waterproof or have been subjected to a waterproof treatment, and are then quilted.

In the figure, reference numeral 54 is a window hole through which the user puts his/her hand out for operation, and is normally closed by a connecting member such as a fastener.

The frame member 3 expands and maintains the surrounding wall body 2 in a desired shape, and is made of wood or the like, for example. The left and right protrusions 5a and 5b of the spinal part 5 are on both sides of the rear part.
The lower end is supported by a support shaft 60.

The chair 4 is of a foldable type, with supports 6 on both sides.
The lower ends of 2 and 62 are provided with guide pins 63 that are fitted into guide grooves 61 formed on the inner surfaces of both sides of the frame member 3, and the seat portions 64 are connected to the support columns 6 on both sides at the center of both sides.
2 and 62, and guide pins 68 are protrudingly provided on both sides of the rear part to fit into guide grooves 67 formed in the rear pillars 66, 66 located inside the both side pillars 62, 62, The upper ends of the rear columns 66, 66 are rotatably connected to the upper portions of the side columns 62, 62 by a support shaft 69, and the lower ends are placed on the frame member 3.

By rotating the both side supports 62 of the chair 4 forward around the guide pin 63 at the lower end, the rear support 66 is lifted from the frame member 3 and rotates around the support shaft 69. It is brought to the support column 62 side. At this time, by providing the guide groove 61 in the frame member 3, the guide pin 63 descends along this, and the upper end of the chair 4 can be lowered to below the height of the storage section 10.

FIG. 12 shows the folding capacity of the chair 4.

This lifts the front end of the frame member 3 and
0 and at the same time lift the front end of the seat part 64 upward, the chair 4 is folded and stored together with the frame member 3 in the storage part 10 formed by the spine part 5.

Next, the left and right front side portions 8a, 8b are turned outward to align with the outside of each front side portion 6b, 7b, and the front side portions 6b, 7b are bent inward.
The inner side surfaces 6a, 7a are folded inward to form the front doors 21a, 21b of the storage section 10 (FIG. 9). In use, it is the opposite of the above. Before use, it is preferable to energize and heat the inside of the device in advance.

Next, FIG. 11 shows a second embodiment. Said Example 1
shows an example in which a neck hole 12 is provided in the cover cloth 9, but the sauna device B shown in this example is designed to accommodate the whole body up to the head, and the sauna device B has a surrounding wall body 70 and a frame member 71. and a chair 72, the frame member 71 and chair 72 having the same structure as the frame member 3 and chair 4 of the previous example. The surrounding wall body 70 is composed of a spine part 73, both side parts 74 and 75, a front part 76, and a covering cloth 77 as in the previous example, and the front part 76 and the covering cloth 7 are divided into left and right parts at the center. Left and right covering cloths 77a, 77b
Translucent windows 78a and 78b are bored above the holder, and a transparent material is attached to the windows.

Other than that, the structure is the same as the previous example except that the overall height is higher to accommodate the whole body, so the explanation will be omitted.

As described above, according to the present invention, the spine part forms the storage part to store the frame members and the chair, and the left and right side parts and the front part serve as the front doors of the folding storage part, so it is extremely convenient for transportation and storage. To use it, all you have to do is open the front door and pull out the frame member and chair inside the storage compartment, and the spine, each partitioned side surface, and the front surface are each equipped with a sheet heating element.
It can be used immediately by energizing it after being expanded, and has advantages such as being easy and quick to use, and since both side parts are held expanded by the frame member, it will not deform during use.
