Description
Technical field
The utility model relates to a kind of thermal protector, particularly a kind of structure improved refrigerant compressor thermal protector, and it is mainly used in the protection that refrigerant compressor is crossed temperature rise, overcurrent.
Background technology
The all supporting starter of present refrigerant compressor and a thermal protector, starter are mainly used in refrigerant compressor and rise and employ, and thermal protector is mainly used in refrigerant compressor and crosses temperature rise, overcurrent protection.During use; Thermal protector is close on the refrigerant compressor shell, when refrigerant compressor when the big electric current, thermal protector internal heating element moment produces big heat and causes the crooked upset of bimetal leaf; And moving contact is broken off, play the protective effect of overload current; In addition; When refrigerant compressor running for a long time for a certain reason, cause the compressor case temperature too high, add and impel the upset of bimetal leaf heated bending after the thermal protector internal heating element produces the heat stack; And moving contact is broken off, played the protective effect of temperature rise.Because of overcurrent and the bimetal leaf of crossing the crooked upset of temperature rise, after residing ambient temperature was lower than the reset temperature that bimetal leaf sets, the bimetallic sector-meeting automatically reset, and makes the thermal protector rearming.Prior art commonly used has following two kinds of structures on refrigerant compressor at present, and still there is certain shortcoming in actual use in the thermal protector of these two kinds of structures, specifically is summarized as follows.
Referring to Fig. 1-Fig. 3; It is stereochemical structure and the plane structural representation of embodiment 1 in the prior art, and it comprises fixed head 1, screw rod 2, cover plate 3, packing ring 4, bimetal leaf 5, contact 6, compound quiet pin 7, housing 8, quiet pin 9, geometrical clamp 10, lead-in wire 11, pin 12 and heating wire 13.There is disadvantage in this structure:
Structural design is reasonable inadequately, installs loaded down with trivial details: need during installation to locate by the spring clip;
Installation cost is high: owing to increased the Spring Card fitting for hose, and thermal protector is installed on the compressor case of three core binding post sides, increased the volume of plastic housing;
Temperature-sensitive poor-performing: because bimetal leaf 5 still has with a certain distance from the shell end face of compressor; Be installed on the compressor case even be close to; Skin temperature will be sensed bimetal leaf 5 and need longer a period of time of air transmitted, can produce certain influence to the over-temperature protection performance.
The above-mentioned shortcoming that this prior art exists needs to solve.
Referring to Fig. 4-Fig. 5; It is stereochemical structure and the plane structural representation of embodiment 2 in the prior art, and it comprises cover plate 14, pin 15, liner 16, connects inserted sheet 17, the quiet pin of base 18, spring leaf 19, bimetal leaf 20, first 21, moving contact 22, fixed contact 23, heating wire 24, the second quiet pin 25.My company of this technology is open in the patent documentation of patent No. ZL200720184795.1, and the installation pattern of compressor case is as shown in Figure 4, is commonly called as to positive triangle and installs, and the domestic Compressors Factory of China all belongs to this kind pattern at present; Positive triangle as as shown in Figure 4 is installed pattern, and its thermal protector base 18 is descending at last, cover plate 14, and heating wire 24 is suspended in topmost under the installment state of this moment; Bimetal leaf 20 is in the centre; Spring leaf 19 below, in case instantaneous large-current appears in thermal protector in actual use, the heating wire 24 under the big function of current is understood sagging under action of gravity; Can contact and short circuit with bimetal leaf 20 after heating wire 24 is sagging; Make the thermal protector cisco unity malfunction thereby blow heating wire 24, this bad phenomenon reflects more on market, and the above-mentioned shortcoming that this prior art exists also needs to solve.
