その構成と欠点を述べる。(b) Conventional Technology A number of hot air type kotatsu using ring-shaped heaters have been proposed in the past, but some of the most representative ones are listed below, and their configurations and drawbacks will be described.

ありた。■ Publication No. 46-17516... A ring-shaped heating element a (I is cleaned and an impeller 1e is provided inside the heating element) below the mounting plate/reflection plate (6). The radiant heat from the heating element heats the protective net (18), causing the protective net to reach a high temperature and causing a risk of burns.Therefore, in order to lower the temperature of the protective net, the distance between the protective net and the heating element must be shortened. Although the size was increased, there was a drawback that the effective space within the punch main body was reduced due to the large thickness of the black part formed by each of the above-mentioned members.

An annular heating element α4 is provided below the annular heating element, and a centrifugal impeller (9) disposed above the annular heating element is rotated by an electric motor (8) to discharge hot air. Similar to technology (2), the radiant heat from the heating element heats the protective cover (13), which becomes hot and causes burns, and also has the disadvantage that the thickness of the heating part is thick (13). Since the car is installed above the heat generating element, the electric motor is located in the flow path of the air taken into the heat generating element, which means that the air flow is poor and the temperature of each component (reflector, protection cover) is low. became dangerous due to high temperatures.

寸法を小さくすることかでさる。(l) In the present invention, the outer diameter of the fan is set to be larger than the outer diameter of the infrared lamp heater. Since it is shielded by the infrared lamp heater, the temperature of the guard directly under the infrared lamp heater is prevented from rising, and there is no risk of getting burned even if your hands or feet touch the guard.In particular, since the first fan has a shielding effect, there is no need for a separate member. The ease of assembly is greatly improved.Therefore, the temperature rise in each part is lowered due to the spreading effect of the fan, which makes it possible to reduce the thickness of the heat generating part.
