Although it forms a curved part, the heater is exposed below the lower edge of the crosspiece and the bent part, so the horizontal direction (circumferential direction) of the heater is
The radiant heat radiated to the inside of the kotatsu body is dissipated upward and around the kotatsu body, and heat loss occurs by the amount of dissipation.
In addition, a part of the outside air that has flowed along the bent portion of the wind guide plate flows out into the upper part of the kotatsu body and around the inside of the kotatsu body, as described above, before being heat exchanged with the heater.
There is a drawback that the heat exchange efficiency of the combined drawn outside air to the warm air is reduced.

る。 Next, talking about the flow of warm air, as shown in Fig. 1, the outside air sucked in mainly from below outside the mounting part 17 by the rotation of the fan 21 hits the lower surface of the wind guide plate 14 and flows along this wall surface in the circumferential direction. The air is exchanged with heat through the space between the heaters 19, 19 and the wind guide plate 14, and is then discharged downward along the lower surface of the shielding plate 14a, expanding the inner space of the kotatsu body from the outer periphery to the center. It circulates efficiently to all parts of the body. At this time, the above-mentioned wind is partly heat-exchanged by the heaters 19, 19, and the rest is heated by the heater 1.
The heaters 19, 19 are spaced a small distance from the wall surface of the wind guide plate 14 to allow the flow of warm air to flow smoothly without being hindered by the heaters 19, 19. Because it is placed in a position where it does not interfere, this warm air can smoothly flow through the shielding plate 14.
It is discharged from the lower outer circumferential surface of the protective guard 23 into the internal space of the kotatsu main body along the direction a. This phenomenon allows the wind guide plate 14 to be cooled and the heater heat to be effectively used for warming the wind guide plate 14.
This results in a reduction in the spatial distance between the heat shield plate 13 and the heat shield plate 13.
そして、ヒーター１９，１９の水平周囲方向へ

方向へ効率良く反射されるため、桟９，９に対す
るヒーター１９，１９による輻射熱の悪影響を防
止し且つ反射熱をロスなくコタツ本体の内部空間
へ反射することができるものである。 Since the radiant heat from the heaters 19, 19 in the horizontal surrounding direction is blocked by the shielding plate 14a and efficiently reflected downward, the adverse effects of the radiant heat from the heaters 19, 19 on the crosspieces 9, 9 can be prevented and reflected. This allows heat to be reflected back into the internal space of the kotatsu body without loss.
すなわち、前記遮蔽板１４ａは外気を効率よく
温風へ熱交換させるとともにこの温風を効率良く

たりするのを、防止することと、この水平周囲方
向への輻射熱を反射熱としてコタツ本体の内部空
間へ反射せしめることとを、作用効果として有し
ているものである。 That is, the shielding plate 14a efficiently exchanges heat from outside air into warm air, efficiently sends this warm air to the internal space of the kotatsu body, and directs the radiant heat from the heaters 19, 19 in the horizontal surrounding direction to the crosspieces 9, 14. The functions and effects are to prevent the heat from being directly irradiated onto the kotatsu body or to dissipate it in the surrounding direction, and to reflect the radiant heat in the horizontal direction into the internal space of the kotatsu body as reflected heat. It is something that exists.

その外径が取付部の径と同径がよい。 In the present invention, a flat reinforcing plate 24 is provided in the center of the protective guard 23 and brought close to the lower surface of the attachment part 17 of the supporting plate 16, but the reinforcing plate 24 is not necessarily necessary, and the protective guard 23 is entirely meshed. The central portion thereof may be close to the mounting portion 17, or may be brought into contact with or screwed onto the mounting portion 17 even if it is not close. Furthermore, if it is provided on the reinforcing plate 24, it is preferable that its outer diameter be the same as the diameter of the attachment part in order to reduce the resistance of the air flow path.

Furthermore, the shielding plate located between the crosspiece and the heater efficiently exchanges heat from the outside air into warm air, and also efficiently guides and sends this warm air to the internal space of the kotatsu body. This prevents thermal effects and allows radiant heat to be reflected back into the internal space of the kotatsu body as reflected heat.
