ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a sauna and more particularly to a portable sauna enclosure having improved characteristics.
BACKGROUND OF THE INVENTION
Steam bath have been popular worldwide recently for health reasons. The only drawback of a steam bath is the high service charge due to the expensive associated facilities. As such, a relatively cheap portable sauna enclosure has been commercially available as shown in FIG.
1
. The sauna enclosure comprises a frame
1
including a plurality of interconnected vertical and horizontal bars, a canopy
2
covered on the frame
1
and stretched by it for forming a space to allow a person to take a bath therein, canopy
2
having three holes
201
for the neck and two arms extending through and a zipper
202
for permitting a person to enter the sauna enclosure when it is unfastened, a steamer
3
outside the sauna enclosure, and a steam pipe
4
connected between the steamer
3
and the inside of the sauna enclosure for transferring steam from steamer
3
to the sauna enclosure. The user should add water into steamer
3
for heating. After bathing, the user should use a dry cloth to absorb the condensed steam (i.e., water) in the sauna enclosure in order to forestall the growth of micro-organisms on the canopy
2
.
However, the previous design suffered from several disadvantages. For example, it is still possible for steam to pass through holes
201
and zipper
202
during bathing due to the gaps between human body (i.e., neck and arms) and holes
201
as well as the gaps in the zipper
202
itself. As such, the leaked steam may be subsequently carried from the bathroom to the other rooms in the house, resulting in a potential damage to the household appliances, furniture, and wall due to humidity. In addition, the assembly and disassembly of frame
1
and steam pipe
4
is a tedious job. Also, the efficiency of steamer
3
may be adversely affected if the packing between steam pipe
4
and steamer
3
is not well sealed. Furthermore, the bulky steamer
4
is not easy to store when not in use. In view of this, its portability is adversely affected. Thus, it is desirable to provide an improved portable sauna enclosure in order to overcome the above drawbacks of the prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a portable sauna enclosure wherein the person enclosed therein may be exposed to dry heated air so as to induce sweating.
It is another object of the present invention to provide a portable sauna enclosure wherein the person enclosed therein may also be exposed to infrared emitted from a heated infrared layer in the enclosure for helping the metabolism of human body.
To achieve the above and other objects, the present invention provides a portable sauna enclosure comprising a foldable frame, a canopy, and a control device. Frame includes a plurality of pivotably connected boards. The canopy is covered on the frame and stretched by it for forming a space. The canopy includes a band along the internal edge of the neck hole having a Velcro© fastener on either end for securing together for preventing dry air from leaking when the band encloses the neck of the person who takes a bath, two side straps on the back of canopy each having a Velcro© fastener on the open end for securing together in folding the canopy, and a handle. A control device is provided on a side of canopy. A heating element for generating dry heated air is provided on the inner surface of the frame. A heat resistant layer is sandwiched between the heating the element and the frame. A protective layer is formed on the heating element for preventing a person from injury due to direct contact with the high temperature heating element.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
