Description
Technical field
The utility model relates to refrigerator heater, particularly relates to a kind of refrigerator heater with leakage protection.
Background technology
Current heater for defrosting of refrigerator adopts parcel silicon rubber and heat-shrink tube to insulate mostly, when refrigerator defrost, heater works, the generation of defrosting water will shorten the effective and safe distance between heater and evaporimeter, once insulation breakdown, be easy to cause heater line to leak electricity, electric current conducts to refrigerator body shell by defrosting water, evaporator pipeline etc., and human body is once contact, then easily there is electric shock phenomenon, cause potential safety hazard.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of leakage protection structure of refrigerator heater, when electric leakage occurs heater, leakage current can be imported the earth by compressor bottom board, thus avoid potential safety hazard.
The utility model is that technical solution problem adopts following technical scheme:
The composition of the leakage protection structure of a kind of refrigerator heater of the utility model comprises: heater, heater conductor, the first stainless steel contact rod, the second stainless steel contact rod, heat-shrink tube and silastic-layer, one end of described heater is connected with one end of the first stainless steel contact rod, the other end of described first stainless steel contact rod is connected with power firestreak by heater conductor, the other end of described heater is connected with the second stainless steel contact rod, and the other end of described second stainless steel contact rod is connected with zero-power line by heater conductor; Silastic-layer and heat-shrink tube is disposed with in the outside of described first stainless steel contact rod and the second stainless steel contact rod;
Its design feature is: between described heater and the first stainless steel contact rod, arrange a ground terminal; Described ground terminal is connected with refrigerator earth terminal by earth lead.
The design feature of the leakage protection structure of the utility model refrigerator heater is also:
Arranging described heat-shrink tube is double hyer insulation Rotating fields, and the thickness of described double layer of insulation is not less than 3.5mm.
Described ground terminal adopts stainless steel material.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, heater leakage current is conducted to the earth by earth lead by arranging ground terminal by the utility model, avoids potential safety hazard, ensures personal safety.
2, the utility model is by being set to double-decker by heat-shrink tube, overcomes the defect that heater for defrosting of refrigerator in the past only has silicon rubber and heat-shrink tube single layer dielectrics, thus improves the insulating properties of heat-shrink tube.

Detailed description of the invention
In the present embodiment, as illustrated in figs. ia and ib, a kind of composition of leakage protection structure of refrigerator heater comprises: heater 1, heater conductor 2, first stainless steel contact rod 3a, second stainless steel contact rod 3b, heat-shrink tube 4, ground terminal 5 and silastic-layer 6, one end of heater 1 is connected with one end of the first stainless steel contact rod 3a, the other end of the first stainless steel contact rod 3a is connected with power firestreak by heater conductor 2, the other end of heater 1 is connected with the second stainless steel contact rod 3b, the other end of the second stainless steel contact rod 3b is connected with zero-power line by heater conductor 2, silastic-layer 6 and heat-shrink tube 4 is disposed with in the outside of the first stainless steel contact rod 3a and the second stainless steel contact rod 3b, arrange heat-shrink tube 4 for double hyer insulation Rotating fields, the thickness of double layer of insulation is not less than 3.5mm.Stainless steel contact rod is connected between heater conductor and heater, and it is overall by heat-shrink tube double wrapped together with silicon rubber again after carrying out silicon rubber vulcanization;
Ground terminal 5 is provided with between heater 1 and the first stainless steel contact rod 3a; Ground terminal 5 is crimped on stainless steel contact rod close to heater place; Ground terminal 5 adopts stainless steel material, and is connected with refrigerator earth terminal 9 by earth lead 8.
See Fig. 2, in freezer compartment of refrigerator 14, refrigerator defrosting heater 1 is fixed on the below of refrigerating evaporator 13, when refrigerator heater 1 works, on evaporimeter, the thawing of frost shortens the effective and safe distance of heater charging member and evaporator pipeline, when the fluctuation of experience domestic electric network or thunderstorm hour, moment, excessive voltage was once after puncturing the insulating elements such as silicon rubber, leakage current conducts to compressor bottom board 10 by the earth lead 8 in ground terminal 5 and refrigerator body, because compressor bottom board 10 is steel plate materials, therefore leakage current can be imported the earth by power line ground wire 11, avoiding leakage current, to conduct to the human electric shock that outcase of refrigerator brings dangerous.
