以上に上昇されがちであり、該感温素子は正確な
室温を検知できない不都合があつた。 Generally, in a heater using a burner, the combustion control of the burner and the room temperature control by the heater detect the room temperature with a temperature sensing element attached to the heater body.
This is done by using the output of the temperature sensing element corresponding to the detected temperature, but the air around the temperature sensing element tends to rise above room temperature due to the influence of radiant heat from the combustion of the burner. The thermosensor had the disadvantage of not being able to accurately detect room temperature.

る。 In order to eliminate this inconvenience, a fan with an air outlet facing the temperature sensing element is installed near the temperature sensing element, and the fan forcibly blows indoor air to the temperature sensing element. Although it is possible to accurately detect the room temperature using an element, this method requires a separate dedicated power source such as a storage battery or an external AC power source to drive the fan, which is not preferable under current energy saving measures. In this case, it is desired to drive the fan without using a separate dedicated power source using a thermoelectric generating element developed in recent years.

The element and the n-type FeSi 2 element doped with Co, etc. are joined at their tips to form a heating section, and an output terminal is provided at the sink section at the tail end of the device, and the heating section and the sink section are connected from between both terminals. It is designed to extract a relatively large electromotive force according to the temperature difference between the two.

揮し得ない不都合を生ずる。 When driving a fan using this element, it is generally considered that a plurality of these elements are placed in their respective heating parts facing the combustion surface of a burner, and the combustion flame of the burner heats these heating parts. A temperature difference between the thermoelectric generating elements and the sink portion is generated, a thermoelectromotive force corresponding to the temperature difference is generated from the output terminal of each thermoelectric generating element, and the fan is driven by this electromotive force. However, in this case, the dimensions of the thermoelectric generator are extremely small, for example, 25 mm x 6 mm x 4 mm, so the radiant heat from the combustion flame also acts on each sink part, causing the temperature of the sink part to increase over time. As a result, the temperature difference with the heating section is reduced, and the characteristics are also deteriorated, resulting in the inconvenience that the above-mentioned excellent performance cannot be exhibited.
