) generates heat and heats the air inside the main body case (1). As a result, the temperature of the air inside the main body case (1) increases, and the heated air becomes an air flow (a) and flows out of the main body case (1) through the exhaust port (9), and the guide plate (7) ) is sent indoors to warm the room. By the amount of air that flows into the room from the main body case (1), the cold air in the room flows through the main body case (1) from the air intake port (8) at the bottom of the panel as shown in air flow (b).
The cold air that flows into the room is heated by the heater (10) and flows out into the room from the exhaust port (9) as described above, so that the indoor air is circulated through the heater, and the indoor air is thereby heated. This creates convection, which heats the room.

The heated air inside loses the outgoing light, and the main body case (1)
Trapped inside. As a result, the heated air inside the main body case (1) is further heated by the heater (10) and heats the main body case (1), and the main body case (1) rises in temperature to a high temperature, causing burns to those who touch it. In extreme cases, it may cause a fire.

ある。[Problems to be Solved by the Invention] In the electric heater configured and operated as described above, when the heater (10) is energized and heating is performed, the radiant heat of the heater (10) may damage the main body case ( The front panel (2) and rear panel (3) of 1) may become overheated and rise to a high temperature, or the top panel (4) of the main body case (1) may become hot due to hot air flowing out from the exhaust port (9). Problems such as: There is also an overtemperature preventer (
12) is attached to the top surface of the guide plate (7), so in the event of an abnormality such as when the exhaust port (9) is blocked by a blanket, etc., the overtemperature rise preventer (I2) is installed around the heater (1 (1)). It takes time to detect high temperature, and overtemperature preventer (12
) before operating the main body case (1) or front panel (2).
Problems such as heating to high temperatures tend to occur.

In the main body case, a front heat shield plate and a rear heat shield plate are provided between the heater and the front panel and between the heater and the rear plate, respectively, and the structure is configured such that air passes through the upper surface of the guide plate. Furthermore, an overtemperature rise preventer was installed inside the main body case opposite the heater.
［作用コ
まず前後遮熱板の配置により、ヒータの周辺への放熱が
減少し、空気へのヒータの伝熱効率が向上する。[Operations] First, by arranging the front and rear heat shield plates, heat radiation to the surroundings of the heater is reduced, and the heat transfer efficiency of the heater to the air is improved.

板との間、及び後面板と後遮熱板との間を流れる空気流
が発生するが、その空気流の温度はヒータの輻射熱を受
けず室温より若干高い程度となるので、前面パネル及び
後面板の過熱が防止される。In addition, due to the arrangement of the front and rear heat shields, an air flow is generated between the front panel and the front heat shield, and between the rear panel and the rear heat shield, but the temperature of the air flow is lower than that of the heater. Since the temperature is slightly higher than room temperature without receiving radiant heat, overheating of the front panel and rear panel is prevented.
さらに案内板の上面を室温より若干高い程度の温度の空
気が流れるので、上面板の過熱が防止される。Furthermore, since air at a temperature slightly higher than room temperature flows over the upper surface of the guide plate, overheating of the upper surface plate is prevented.
さらにまた本体ケース内にヒータに対向して温度過昇防
止器を装着したので、排気口の閉塞などによるヒータ周
辺の過熱を早期に検知してヒータへの通電を遮断し、ヒ
ータ過熟による危険発生を防止できることとなる。Furthermore, an overtemperature rise prevention device is installed inside the main body case facing the heater, so overheating around the heater due to blockage of the exhaust port can be detected early and power to the heater can be cut off, creating a risk of overheating. This means that the occurrence can be prevented.
