That is, a groove for inserting the heat generating panel 10 is formed on the upper surface of the bed 1, and the heat generating panel 10 is inserted into the groove so as to be horizontal with the edge height of the bed 1.

Guide rails la are mounted on upper edges of both longitudinal sides of the bed 1 to guide the slider cover 3 so that the slider cover 3 does not come off the bed 1 when sliding.

On the side surface of the bed 1, at least one drawer 19 for accommodating various objects is provided.

It goes without saying that the drawer 19 may be equipped with a normal roller rail or the like so as to facilitate opening and closing.

On the other hand, a heat insulation material such as urethane foam is interposed between the upper surface of the bed 1 and the heat generating panel 10, thereby minimizing heat loss during heat generation.

The heat generating panel 10 is formed of a regenerative type and generates heat when power is supplied to perform a function and a role of fomiting a body part of a user's body, and also generates a far-infrared ray and an anion.

4 and 5, the heat generating panel 10 includes a rectangular tubular frame 11 having an opened upper surface, a built-in tubular frame 11, A charcoal grain 13 which surrounds the heating wire 12 in the interior of the wooden frame 11 and receives heat radiated from the heating wire 12 to store and discharge heat; A lower protective nonwoven fabric 14 having a surface coated with loess powder and a plurality of wiring grooves 15a for maintaining the wiring state of the heating wire are formed at a predetermined interval, A partition plate 15 which divides the internal space of the wood frame 11 into a plurality of cells to facilitate the flow and prevent the flow of the charcoal particles 13 and a partition plate 15 which is fixed to close the upper surface opening of the wooden frame 11, (16a) formed at a predetermined interval and a plurality of wooden upper plates (16) A ceramic plate 17 having a plurality of ceramic stones 17a fixed to the mount holes 16a and having ventilation holes 17b at inner and outer peripheries thereof and a plurality of charcoal grains 13 attached to the top plate 16, And a top-controlling non-woven fabric 18 on which a loess powder is coated and fixed on the surface thereof to prevent leakage and loss through the mount hole 16a of the ceramic block 17a and the vent hole 17b of the ceramic block 17a.

On the other hand, the ceramic stone 17a is preferably formed by mixing 1 part by weight of tourmaline powder with 10 parts by weight of the elvan powder, and sintering or firing at about 1100 to 1200 占 폚. For example, when the total composition ratio is 100%, it can be formed by blending 89% of elvan and 11% of tourmaline. At this time, if the compounding ratio of tourmaline exceeds 11%, tourmaline may react rapidly to the human body, resulting in redness or irritation of the skin. Conversely, if the blending ratio of tourmaline is less than 8%, there may be a problem that the useful reaction to the human body does not occur properly.

Here, the blending ratio of the ceramic stone 17a refers to a relative content ratio when the content of the elvan powder and the tourmaline powder is 100, which means that the inventors have repeatedly experimented with trial and error to implement the object of the present invention And it is not intended to impose any particular limitation on the upper limit or the lower limit.
