Description
Technical field
The utility model belongs to technical field of refrigeration compressors, is specifically related to a kind of sucking pipe and exhaust pipe structure that prevents the refrigeration compressor of refrigeration system electric leakage
Background technique
Along with improving constantly of living standards of the people, refrigeration system such as air-conditioning, refrigerator, refrigerator, ice making machine, enter in the daily life of ordinary people along with various household electric appliance more and more with the drinking machine of refrigerating function with the cabinet etc. of spilling of refrigerating function, yet the safety problem that is caused by the refrigeration system electric leakage also manifests thereupon and is paid close attention to by people.
Refrigeration system is made of parts such as refrigeration compressor, condenser, throttle valve and vaporizers, consists of refrigerant circuit (also claiming the refrigeration system loop) by the pipeline connection between these parts.The characteristics that generally require pipeline to have convenient bending and be convenient to weld must be born again the easy sealing in higher refrigerant pressure and joint simultaneously and difficult the leakage, and therefore adopting copper pipe to fill the post of aforesaid pipeline is generally acknowledged at present selection.And consist of aforementioned condenser, throttle valve and the vaporizer etc. of refrigeration system because require to have thermal conductivity, sealing joint, refrigerant pressure ability to bear, cold-hot, oil resistant and corrosion-resistant aging etc., therefore also usually adopt metallic material to make.Refrigeration compressor namely is connected with the refrigeration system loop with aforesaid refrigerant circuit with sucking pipe by the outlet pipe that is fixed on its housing, more particularly be connected with aforesaid copper pipe, Placement is the uninsulated direct connections such as welding or cutting ferrule, and other parts in the refrigerant circuit are also similar with being connected of copper pipe.Therefore, under normal conditions, whole refrigeration system is actually the interconnect conductive body that the copper pipe that conducted electricity well couples together, and refrigeration compressor demand motive motor (being compressor electric motor) wherein drives operation.At present, basically the drive motor of the employed refrigeration compressor of all domestic refrigeration system all is to be enclosed in the housing of refrigeration compressor, and has preferably insulation measures, therefore, can not make circuit be connected to the interconnected conductor of aforesaid refrigeration system during drive motor energising work generally speaking.But, at refrigeration compressor through long-time running and the wearing and tearing that cause enough greatly the time, when perhaps refrigeration compressor abnormal failure occurs and causes insulation measures to go wrong, the circuit of drive motor might with the interconnected conductor conducting of refrigeration system, thereby make refrigeration system generation leaky.In this case, the personnel that touch refrigeration system just have electric shock feeling, when serious even cause the casualty accident of getting an electric shock.
For the problems referred to above; people tend to expect using residual current operated protective device; use and make the user avoid the electric shock accidents that causes because of electric leakage; but not all household electric appliance of refrigeration system that contain are all with residual current operated protective device; and residual current operated protective device also has the situation that breaks down and can't embody protective function; at this moment, the electric leakage of refrigeration system will be fatal undoubtedly.
The applicant has carried out literature search, has searched two pieces of reference, document A) publication number be CN1888510A, name is called " pipe joint "; Document B) notice of authorization number is CN201568670U, and name is called " a kind of sealed insulation pipe joint ".
Above-mentioned document A) although has the capable described technique effect of Instructions Page 2 10-12, but the anxiety that in the large situation of loine pressure and cold and hot distortion, has refrigrant leakage, come from namely that the disconnection port area of refrigeration agent between first, second interface in first, second through hole oozed and the slot of the boss of insulation shell and first, second interface, thereby insulation function is reduced and even forfeiture.Above-mentioned document B) noticed document A) shortcoming (specifically can referring to the background technique hurdle of the 1st page in the specification of this patent), junction plane place at a pair of pipeline section of copper pipe has set up an anti-fluorine, oil resistant and resistant to elevated temperatures O RunddichtringO, uses the sealing effect that improves pipe joint.This sealed insulated joint can make in heat pump water heater system between the pipeline of the heater of heat pump water heater and refrigeration system and the refrigeration compressor and realize completely electric insulation isolation, therefore can stop the water heater electric leakage accident that causes because of refrigeration compressor or pipe-line system electric leakage.But be only applicable to the electric insulation isolation to the condenser of refrigeration system, and for other household electric appliance that use refrigeration system as the aforementioned refrigerator and air-conditioning etc. be inadequate because these household electric appliance require the position of whole refrigeration systems that the every user beyond the refrigeration compressor is touched easily to carry out the electric insulation isolation.
In addition, because above-mentioned two patent schemes all are to be connected on the refrigeration system pipeline as independent parts, therefore not only increased the amount of parts of refrigeration system, and increased the assembling work amount and assembled complexity, and the cost that has improved refrigeration system, thereby be difficult to promote the use of at the product of the production in enormous quantities such as refrigerator and air-conditioning.
In view of above-mentioned prior art, be necessary to be improved, for this reason, the applicant has done useful design, and technological scheme described below produces under this background
