ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a sauna chamber. More specifically, the present invention relates to an improved sauna made with illite surfaces, wherein each wall within a sauna chamber including a bottom portion thereof is formed of an illite composite material for thereby promoting conspicuous therapeutic effects together with deodorization effect.
A generally known illite refers to a group of clay minerals formed by weathering or hydrothermal alteration of other aluminium-rich minerals, and it is also known that illite occurs intermixed with kaoline and other clay minerals. Whereas, illite powder denotes natural radioactive clay particles that radiate a healthful quantity of infrared radiation.
Illite is also known as Bio-Light Stone or Sang Gwang Suk (Korean for Bio-Light Stone), as the illite powder radiates faint glow, and it can be naturally extracted from a clay deposit in form of powder, or rock that can be finely ground into a powder form. The main ingredients for illite powder are believed to be SiO

. The best illite powder for this invention comes from Republic of Korea, from the mines of the mining town of San-Ik-Rhee, the township of Young-Dong-Gun, the province of Choong-Chung-Book-Do.
Also, illite has been used for various industrial or residential purposes. For example, illite is a crucial element in sewage treatment because it has a certain antibacterial effects. Illite further generates strong negative ions that neutralize positive ions incurring bad odor.
The inventor found that the synergetic combination of illite and sauna significantly enhances therapeutic effects expected by most sauna users. Therefore, it is an object of the present invention to provide a sauna made with illite surfaces which is capable of deodorizing and pasteurizing the atmosphere within the sauna.
Another object of the present invention is to generate a healing or therapeutic effect for sauna users by taking advantage of an illite characteristic, wherein illite radiates far infrared radiations that are known to generate numerous positive effects on human body.
SUMMARY OF THE INVENTION
To achieve the aforementioned objects and other objects, a sauna according to the present invention comprises an internal enclosure member, an external enclosure member and a means for heating an internal cavity formed by the internal enclosure member. Here, the heating means may be one selected from a heated rock, an electrical heater and other commonly known sauna heating devices.
The internal enclosure member has a bottom portion, side portions and a ceiling portion, wherein the internal enclosure member is attached to the external enclosure member. The bottom portion, the side portions, and the ceiling portion of the internal member may be respectively composed of about 10 to 90 percent illite by mass.
According to an improvement of the present invention, the bottom portion of the internal enclosure member may be composed of about 50 to 90 percent illite by mass. Also, the side portions and the ceiling are respectively composed of about 20 to 50 percent illite by mass. Preferably, the respective bottom portion, side portions and the ceiling portion may be also composed of about 20 to 50 percent illite by mass.
For a better performance, the internal enclosure member may be formed unitary with the external enclosure member. Selectively, a plurality of illite particles are densely populated within the internal enclosure member in a constant and regular illite concentration. Further, the illite concentration in the internal enclosure member may become incrementally greater toward the cavity.
The advantages of the present invention are numerous. First, the illite composite sauna wall deodorizes hazardous gas and/or bad smell in the air, thereby realizing a clear atmosphere within the sauna. Second, illite pasteurizes the atmosphere by intensively radiating negative ions and subsequently provides an antibacterial effect, thereby securing a healthy and refreshed air to the full satisfaction of the sauna users. Third, the illite mineral radiates far infrared radiations of 3 to 25 &mgr;m in wave length for thereby generating a therapeutic effect on the sauna users.
Although the present invention is briefly summarized, the fuller understanding of the invention can be obtained by the following drawings, the detailed description and appended claims.
