A heating element unit composed of a protective net having a fibrous treatment layer on the surface, and a yagura having a plurality of cross beams in the inside and having an outer frame provided on the outer periphery of the middle beam, In the heating table including the legs arranged at the four corners of the tower, the heating unit incorporated inside the middle crosspiece of the girder has a lower position of the outer peripheral wall of the support plate with respect to the lower surface portion of the middle crosspiece. It is located on the same plane or the lower side, and the outer peripheral wall surrounds four directions , By forming the recessed space, in the heating element unit arranged in the middle crosspiece of the girder, radiated and radiated at a high temperature of about 300 to 500 ° C. from the heating element, and Warm the floor.

[0010] Further, four directions of the outer peripheral portion of the support plate are surrounded,
Since the heating element is located in the wall in which the recessed space is formed and above the support plate, the heating element is surrounded in four directions in the support plate of the heating element unit, and convection heat accumulates in the recessed space, and the heating element unit is formed. Convection heat to the outer peripheral portion is difficult to escape, and the outer peripheral wall is extended to the same plane as the middle crosspiece or to the lower side, and a relatively high temperature heat pool is created in the concave space surrounding the four sides.

Next, secondary radiation is generated by the heat radiating plate provided with far-infrared rays disposed in the concave space of the support plate having the heat pool obtained above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3. FIG.

Reference numeral 1 denotes a heating element serving as a heat source for heating the inside of the tower 10, which has a generally known configuration such as a quartz lamp type heater, a quartz tube type heater, a sheathed heater type, and a combined type combining these. Things.

Reference numeral 2 denotes a reflection plate for efficiently reflecting the heating element 1 into the scaffold 10, and is disposed so as to cover the upper part of the heating element 1.

Reference numeral 3 denotes a safety device for detecting a temperature when an abnormality or failure occurs in the heating element unit 7.

Reference numeral 4 denotes a controller for controlling the temperature inside the heating element unit 7 and controlling the temperature inside the tower 10.

Reference numeral 14 denotes a radiator plate located near the heating element 1 and provided with far infrared rays on its surface.

Reference numeral 5 denotes the heating element 1, the reflector 2, and the safety device 3.
The heat radiation plate 14 is incorporated therein, and the outer peripheral portion has a concave wall. The outer peripheral wall is a support plate having a shape surrounding four directions and forming a concave space.

Reference numeral 6 denotes a protective net which has a fibrous treatment layer on its surface and is located below the support plate 5.

Reference numeral 7 denotes a heating element unit which comprehensively constitutes the above-mentioned components.

Reference numeral 8 denotes a middle crosspiece which has a plurality of insides and is formed in a cross-girder shape.

Reference numeral 9 denotes an outer frame provided on the outer peripheral portion of the middle crosspiece 8, which is made of wood, plastic, or the like.

Reference numeral 10 denotes a scaffold composed of the middle crosspiece 8 and the outer frame 9.

Reference numerals 11 denote legs arranged at the four corners of the tower 10, which are made of wood or plastic.

Next, the operation of the above configuration will be described.

With the above-described structure, in the heating element unit 7 disposed in the middle beam 8 of the girder, the heat is radiated and radiated at a high temperature of about 300 to 500.degree. Warm the space and floor inside 10.

Next, a heating element unit 7 is formed in a support plate 5 having a wall on the outer periphery where a concave space is formed surrounding four sides, and is formed in four directions on the outer periphery of the support plate 5. Since the heating element 1 is located inside the wall forming the recessed space and above the support plate 5, the heating element unit 7 is surrounded in four directions in the support plate 5 of the heating element unit 7 and is located in the recessed space. Convection heat accumulates, making it difficult for the convection heat to escape to the outer peripheral portion of the heating element unit 7. Further, the outer peripheral wall is extended to the same plane or lower side as the middle rail 8, and a relatively high temperature is formed in the concave space surrounding the four sides.

[0029]

According to the present invention, since the heating element is located in the wall of the outer peripheral portion of the support plate and above the support plate, convection heat to the outer peripheral portion of the heating element unit is less likely to be transmitted. Extends the outer peripheral wall to the same plane as the middle crossbar or to the lower side,
The outer wall is formed in a shape that surrounds the outer wall in four directions to form a recessed space and to keep heat in the recessed space, making it difficult to escape. It can be used while keeping the temperature of the table from rising.

Further, by disposing the heat radiating plate provided with the far-infrared ray in the concave space provided with the relatively high temperature heat pool, the radiant heat of the heating element and the secondary radiation from the heat radiating plate are generated together. Therefore, a useful heating table can be provided such that the floor and the table space can be efficiently heated.
