部で室温が表示される。7 is a combustion filter and is attached to the right side of the rear plate 2.
The heat sensing portion at the tip of the thermistor 8 is located at the opening of the combustion filter 7, and the rear plate 2 and the thermistor 8 are fixed by a fixing band 9. The thermistor 8 is connected to the control board 10, and the fan 4 draws in air from outside the appliance through the opening of the combustion filter 7. The tip of the thermistor 8 senses the temperature, which is controlled by the control board 10 and displayed on the appliance. The room temperature will be displayed.

れるまで器具をある程度運転させる時間を要した。Problems to be Solved by the Invention However, with the above configuration, the room temperature is displayed correctly under normal operating conditions, but when the switch is turned off,
After the fan 4 rotates for several minutes and then stops, when the fan 4 is turned on after a while (when it is re-ignited), the room temperature display is higher than the actual room temperature. This is because when the fan 4 stops, the combustion chamber 5 is still hot, and the residual heat is transferred to the tip of the thermistor 8. When relighting, it took some time to run the appliance until the room temperature was displayed correctly.

し、異なる部分を中心に説明する。EXAMPLE An example of the present invention will be described below based on the drawings. FIG. 1 shows a perspective view of a gas hot air heater according to an embodiment of the present invention, with the right half cut away. The same parts as those of the above-mentioned conventional example are given the same reference numerals, detailed explanations are omitted, and different parts will be mainly explained.

る。In FIG. 1, 2 is a rear plate, 4 is a fan, 5 is a combustion chamber, and 7 is a combustion filter. 8 is a thermistor, and the rear plate 2 and the thermistor 8 are fixed by a fixing band 9, and the tip of the thermistor 8 is attached to the bottom, both sides, and the front 4.
A heat shielding box 11 surrounding the surface is provided and fixed to the rear plate 2. The upper part of the tip of the thermistor 8 and the combustion filter 7 side are left open.

とができる。In normal operating conditions, the fan 4 sucks air from outside the appliance through the opening of the combustion filter 7, and the heat shield box 11
Air flows from the combustion filter 7 side to the top, and the tip of the thermistor 8 senses the room temperature. At the time of re-ignition, the heat shield box 11 prevents residual heat from the combustion chamber 5 from being transmitted to the tip of the thermistor 8. Since the combustion filter 7 side of the heat shield box 11 is open, the tip of the thermistor 8 is not exposed to the outside of the appliance. It can come into direct contact with the air. Therefore, the room temperature display under normal operating conditions is displayed correctly, and the room temperature display at the time of re-ignition can also be displayed correctly without being displayed higher than the actual room temperature.
