４２号公報に示すような構成が一般的であった。Prior art This type of conventional hot air heating device was developed in Utility Model Publication No. 59-1785.
A configuration as shown in Publication No. 42 was common.
以下、その構成について第６図、第７図および第８図を

て運転を停止するようになっていた。When the hot air heating device is operated with the above configuration, the air flowing into the main body 1 of the hot air heating device from the outside air suction port 5 is pressurized by the blower 2, passes through the blowing air path 6, is heated by the heating element 3, and becomes warm. Air is blown out from the wind outlet 4. In the event that the hot air outlet 4 becomes blocked, the temperature inside the outlet air passage 6 rises and the overheating prevention device 7 is activated to stop the operation.

。Problems to be Solved by the Invention In such a conventional hot air heating device, a temperature overheating preventer 7 is disposed in the blowout air passage 6, so that the temperature overheating preventer 7 is prevented by the heating element 3. Since the temperature of the heated air is sensed, the operating temperature must be raised, and if the hot air outlet 4 is partially blocked, overheating cannot be prevented with just the temperature increase in the air outlet 6. Since there was also a flow of air near the vessel 7, the temperature overheat protector 7 could not be activated. In other words, if you try to operate the overheat protector 7 when the hot air outlet 4 is partially blocked, the operating temperature of the overheat protector 7 must be lowered, causing a slight rise in the room temperature. The operating temperature could not be lowered unnecessarily, and the hot air outlet 4 was partially blocked, as problems such as variations in input voltage and product assembly caused the product to operate in a normal state. Under this condition, the temperature overheat protector 7 could not be activated.
本発明は上記課題を解消するもので、温風吹き出し口が

In an abnormal case where the hot air outlet is only partially blocked, the heated air near the hot air outlet will flow through the through hole to the blower, causing the overheating preventer to close. The ambient temperature rises rapidly and the overheat protector activates in a short time.

ケース８内には外気吸い込み口９と温風吹き出し口１０
を連通ずるＬ型の吹き出し風路１１が設けられている。Inside the case 8, there is an outside air inlet 9 and a hot air outlet 10.
An L-shaped air outlet duct 11 is provided that communicates with the air.
吹き出し風路１１の垂直部１２の上部には送風１１１３

の小さい吹き出し風路１１内へ空気が流れる。In the above configuration, the operation will be described. During normal operation, air sucked through the outside air suction port 9 passes through the case 8 and then enters the blower 13 through the suction port 20. Blower 1
The air pressurized by 3 is heated by the heating element 16, passes through the blowing air passage 11, and is blown out from the hot air blowing port 10. At this time, air flows through the through hole 18 from inside the case 8 into the blowing air passage 11 where the pressure is low.

度上昇を検知して運転を停止させるものである。Therefore, the pressure within the horizontal portion 17 of the blowing air passage 11 increases. Therefore, at this time, the blower 13, which was sucking the air inside the case 8 that flowed in from the outside air suction port 9,
The heated air stagnant in the blowout air passage 11 through the through hole 18 is also sucked. In this way, a flow of heated air is created from the through hole 18 to the suction port 20 of the blower 13, and the overheating preventer 19 in the flow detects a temperature rise and stops the operation.
