スの充填過多・過少、または膨脹弁のセツト圧力
の間違いなどで異常な温度上昇を招き、結果とし
て焼損という重大な問題を生じることがある。 In general, compressors for coolers can cause abnormal temperature rises due to the wrong type of refrigerating oil specified, overfilling or underfilling of refrigerating oil, overfilling or underfilling of refrigerant gas, or incorrect setting pressure of the expansion valve, resulting in burnout. This can lead to serious problems.
従来、このような問題を防ぐために、コンプレ

うという問題が生じる。 Therefore, it is possible to create a circular hole on the compressor side that is easy to mold, and insert a thermal protector using a rectangular cylindrical metal container that fits into this hole, but in this case, there is a gap between the compressor hole and the thermal protector. This creates a problem in that air-tightness cannot be maintained and Freon gas inside the compressor leaks out.

ムが用いられる。 The metal container 13 has a cylindrical insertion part 1a into the compressor body, and has an inclined surface with an inclination angle of 30° to 60° so that the opening upper end 13b can be brought into close contact with the outer peripheral surface of the compressor main body via the heat-resistant rubber packing 16. The opening lower end portion 13c is formed into a cylindrical shape having a diameter larger than the diameter of the insertion portion 13a. The metal container 13 is made of corrosion-resistant aluminum, which is the same material as the compressor.

3 is provided with a mount body in which a fixed electrode plate 4 and a movable electrode plate 5 are integrated with a resin bead 2, and electrode leads 10 and 11 extending outward from the resin bead 2 are provided with a mount body as shown in FIG. As shown in FIG.
4a, it is positioned with the metal container 13, and the sealant 1 is inserted into the gap at the open end.
5 and sealed. The sealant 15 is prevented from flowing into the cylindrical portion of the metal container 13 by a shield 14 attached to the mount body.
Therefore, there is no possibility that the opening/closing operation of the thermally responsive switch will be hindered by the flow of the sealant 15 into the cylindrical portion, and the open end of the metal container 13 is reliably sealed.

る。 Further, the covering portions of the electrode leads 10 and 11 are passed through holes provided in the center of the mounting screw 8. As a result, when the electrode leads 10, 11 are bent, the fulcrum is formed at a location away from the root of the electrode leads 10, 11, so the bending causes damage to the sealant 15, causing the thermal protector 1 to leak. The risk of this happening is extremely reduced.

The mounting screw 18, in which the covering portions of the electrode leads 10 and 11 are inserted into the hole 19 in the center, is screwed into the threaded portion of the mounting portion 17 of the compressor body until the Freon gas inside the compressor does not leak out, until it is in complete contact. Therefore, the thermal protector 1 is fixed to the compressor body.

る。 As explained above, the thermal protector device of the present invention has a structure in which the thermal protector is inserted into the compressor body, so it has good thermal response and therefore can improve safety and reliability. The efficiency of the cooling cycle can be improved. In addition, the thermal protector device of the present invention has a packing interposed between the inclined surface of the flange portion of the thermal protector and the outer circumferential edge of the compressor body, and the mounting screw is screwed into the threaded portion of the compressor body from the outside. Since it is tightened, it is possible to reliably prevent leakage of Freon gas in the compressor of an air conditioner, for example. Furthermore, by providing the insulating plate on the covering portion of the electrode lead, it is possible to prevent the sealant from flowing into the metal container, and there is no risk of interfering with the opening/closing operation of the thermally responsive switch. Furthermore, since the covering part of the electrode lead is inserted into the hole of the mounting screw, the fulcrum when the electrode lead is bent is formed at a location away from the root of the electrode lead. It is also possible to eliminate the fear that the thermal protector itself will leak due to damage.
