Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sweating device used as a home sauna bath.

Generally, as a sweating device that is convenient to store and transport when not in use, a wall member with a sheet-like heating element is rolled up into a cylindrical shape, and a top lid and a bottom lid are removably fitted to the upper end and bottom end of the wall member, respectively. There is a wall member that has a structure in which the above three parts can be disassembled when not in use or when being transported, and the wall member can be rolled up into a smaller size than when in use.

In such a sweating device, the wall member, which is rolled into a cylindrical shape, must have enough strength to resist buckling during use, and the heat from the heating element must effectively act on the inside of the cylindrical shape. The structure must be such that the heating element will not be easily damaged even if a hard object hits the wall member, both when the heating element is in use and when it is not in use.

However, the wall members of conventional sweating devices are
Since the sheet-shaped heating element was simply bonded and fixed to the inner surface of the synthetic resin sheet, not only did it not have sufficient buckling strength during use, but the heat of the heating element tended to escape to the outside, resulting in poor thermal efficiency. Ta. In addition, there have been cases where the heating element is damaged by directly hitting the heating element with a hard object.

This idea was made based on the above circumstances,
The purpose is to improve buckling strength and heat insulation by constructing the wall member with an inner layer provided on the inner surface of the heating element and an outer layer provided on the outer surface. Another object of the present invention is to provide a sweating device in which the heating element is not easily damaged.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the entire sweating device, which includes a wall member 1 that is rolled into a cylindrical shape and has an inclined upper end surface, and an upper lid 2 that is removably fitted to the upper end of the wall member 1. It consists of a bottom cover 3 that is removably fitted to the lower end. The wall member 1 includes a heating element 6 made of a sheet-like carbon heater 4 covered with an insulating sheet 5 made of vinyl chloride, and the heating element 6.
It is composed of an inner layer 7 provided on the inner surface side and an outer layer 8 provided on the outer surface side. inner layer 7
A net 9 made of synthetic resin and an inner sheet 10 made of vinyl chloride or the like are successively joined to the inner surface of the heating element 6. The outer layer 8 includes a foamed elastic material sheet 11 made of urethane foam, an intermediate sheet 12 made of vinyl chloride, and an outer sheet 13 made of vinyl chloride.
are successively joined to the outer surface of the The outer sheet 13 has a large number of bulges 14 projecting outward over almost the entire length in the height direction, and is formed at predetermined intervals in the circumferential direction, and has a cross section L at one end in the longitudinal direction, as shown in FIG. A letter-shaped engaging portion 15 is formed, and an engaging piece 15a extending from the other end engages with this engaging portion 15. Further, at the upper and lower ends of the heating element 6 and the inner and outer layers 7 and 8 joined to the inner and outer surfaces thereof,
Pressing member 1 made of flexible plastic sheet
6 and 16 are provided.

On the other hand, the top lid 2 and the bottom lid 3 are both formed into a cap shape from relatively hard synthetic resin, and an elastic material 17 such as urethane foam is bonded to the inner bottom surface of the bottom lid 3. . Further, an opening 18 is formed in the upper lid 2, and a through hole 1 is provided in this opening 18.
A cloth 20 having 9 formed thereon is detachably provided by a fastener 21.

The top cover 2 has an elliptical shape because it is fitted onto the inclined upper end surface of the wall member 1 which is rounded into a cylindrical shape, and the bottom cover 3 has a circular shape.

According to the sweating device constructed in this manner, the wall member 1 has a three-layer structure in which the inner layer 7 is provided on the inner surface of the heating element 6, and the outer layer 8 is provided on the outer surface. The inner layer 7 consists of a net 9 and an inner sheet 10 and has almost no heat insulation properties, so the heating element 6
The heat from the wall member 1 is easily dissipated to the inner surface side of the wall member 1.
Therefore, the user who enters the wall member 1, which is rolled into a cylindrical shape, is efficiently heated by the heating element 6. In addition, the outer layer 8 is a foamed permeable material sheet 11.
The heat insulating effect makes it difficult for the heat of the heating element 6 to escape to the outside, so the heat of the heating element 6 effectively acts on the inner surface of the wall member 1, improving thermal efficiency. In addition, since the bulging portions 14 are formed along the height direction of the outer sheet 13, the buckling strength of the outer sheet 13 is improved by the bulging portions 14. The member 1 is less likely to lose its shape during use. Furthermore, since the heating element 6 is protected by the inner layer 7 and the outer layer 8, it will not be damaged by being hit directly with a hard object.

Further, when a user enters the wall member 1 which is rolled into a cylindrical shape, a fabric 20 in which a through hole 19 is formed for the user to take his/her head out is attached to the upper cover 2 by means of a fastener 21. Since the cloth 20 is provided in a removable manner, the cloth 20 can be removed from the upper lid 2 and washed easily.

In the above embodiment, the bottom cover 3 is fitted to the lower end of the wall member 1, but the function as a sweating device can be maintained even without the bottom cover 3. That is, the wall member 1 rolled into a cylindrical shape may be installed and used in a bathroom or the like with the lower end left open.

As described above, the present invention provides a wall member that can be rolled into a cylindrical shape with three layers: a heating element, an inner layer joined to the inner surface of the heating element, and an outer layer joined to the outer surface of the heating element. The inner layer is formed by sequentially bonding the net and the inner sheet to allow the heat of the heating element to pass through easily, and the outer layer has heat insulating properties and buckling strength. Therefore, it is difficult for the heat from the heating element to escape to the outside of the wall member, which is rolled into a cylindrical shape, and the inner layer has almost no insulation properties, so the heat from the heating element is easily dissipated to the inner side. can be heated efficiently. In addition, the buckling strength of the outer layer prevents the wall member, which is rolled into a cylindrical shape, from losing its shape during use, and since the heating element is protected by the inner and outer layers, it can be easily It has the advantage of not being easily damaged.
