Description
Technical field
the invention belongs to technical field of refrigeration compressors, be 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 as air-conditioning, refrigerator, refrigerator, ice making machine, with the drinking machine of refrigerating function and with refrigerating function spill cabinet etc. more and more along with various household electric appliance enter in the daily life of ordinary people, yet by refrigeration system, leaked electricity and the safety problem that causes also manifests thereupon and paid close attention to by people.
refrigeration system consists of parts such as refrigeration compressor, condenser, throttle valve and vaporizers, between these parts, by pipeline, is connected and is formed refrigerant circuit (also claiming refrigeration system loop).Generally require pipeline to have convenient bending and the feature of being convenient to welding, the while must be born again compared with high refrigerant pressure and joint easily seals and difficult leakage, and therefore adopting copper pipe to fill the post of aforesaid pipeline is current generally acknowledged selection.And aforementioned condenser, throttle valve and the vaporizer etc. that form refrigeration system owing to requiring to there is thermal conductivity, sealing joint, refrigerant pressure ability to bear, cold-hot, oil resistant and corrosion-resistant aging etc., therefore also conventionally adopt metallic material to make.Refrigeration compressor is connected with refrigeration system loop with aforesaid refrigerant circuit with sucking pipe by the outlet pipe being 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 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, the drive motor of the refrigeration compressor that all domestic refrigeration system are used is substantially to be all enclosed in the housing of refrigeration compressor, and there is good insulation measures, therefore, generally can not make circuit be connected to the interconnected conductor of aforesaid refrigeration system during drive motor energising work.But, at refrigeration compressor through long-time running and the wearing and tearing that cause enough greatly time, or when refrigeration compressor occurs that abnormal failure causes insulation measures to go wrong, the circuit of drive motor will be likely and 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, even cause the casualty accident of getting an electric shock when serious.
for the problems referred to above; people tend to expect using residual current operated protective device; use and make user avoid the electric shock accidents causing because of electric leakage; but not all household electric appliance that contain refrigeration system are all with residual current operated protective device; and residual current operated protective device also has the situation that breaks down and cannot embody protective function; now, 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 there is the technique effect of Instructions Page 2 10-12 described in capable, but in loine pressure and cold and hot distortion, there is the anxiety of refrigrant leakage large in the situation that, come from that refrigeration agent in first, second through hole disconnection port area between first, second interface is oozed and the boss of insulation shell and the slot of first, second interface, thereby insulation function is reduced and even loses.Above-mentioned document B) noticed document A) shortcoming (specifically can referring to the background technique hurdle of the 1st page, the specification of this patent), junction plane place at a pair of pipeline section of copper pipe has set up a resistance to fluorine, oil resistant and resistant to elevated temperatures O RunddichtringO, uses the sealing effect that improves pipe joint.This sealed insulated joint can make to realize between the heater of heat pump water heater and the pipeline of refrigeration system and refrigeration compressor electric insulation isolation completely in heat pump water heater system, therefore can stop the water heater electric leakage accident causing 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 refrigeration compressor is easily touched to carry out electric insulation isolation.
in addition, because above-mentioned two patent schemes are to be all connected on refrigeration system pipeline as independent parts, therefore not only increased the amount of parts of refrigeration system, and increased assembling work amount and assembled complexity, and the cost that has improved refrigeration system, thereby be difficult to promote the use of on 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.
