Description
Technical field
The utility model is related to double-deck double low surface loading refrigerator class defrosting heater and the refrigerator with it, belongs to house
Electrical appliance field.
Background technology
The defrosting heater that current refrigerator industry is used is generally divided into three species, is that steel pipe heater, aluminum pipe add respectively
Hot device and quartz tube heater.Wherein, aluminum pipe heater heat is relatively low, is contact conduction defrost, because its exterior line is
Aluminum pipe, bending easy damaged.Quartz tube heater heating is heat radiation conduction, and heating efficiency is high, but because exterior protection is glass
Pipe, it is easily damaged.Therefore, the conventional defrost of current refrigerator industry is steel pipe heater, this kind of heater heating effect with sensor
Rate is high, while being difficult loss, reliability is higher.To meet R600a refrigerant requirement of explosion proof, steel tube surface hottest spot temperature should not
More than 394 degrees Celsius, but to meet refrigerator defrost requirement, heater power again can not be too low, and this is accomplished by increasing as far as possible
The surface area of heater, conventional steel pipe heater structure such as Fig. 1, heater is distributed in approximately the same plane, can effectively dropped
Low heater surfaces load, but this structure occupies larger spatial area up and down in refrigerator, is made to refrigerator structure design
Into many puzzlements.
Utility model content
The utility model takes that space above and below refrigerator compartment is big, evaporator of refrigerator is unilateral to solve existing defrosting heater
Defrost is bad, and there is provided a kind of double-deck double low surface loading refrigerator class defrost heating with the problems such as easily icing at drip tray discharge outlet
Device and the refrigerator with it.The structure design of this new optimization refrigerator defrost steel pipe heater, is set using each biexhaust pipe up and down
Meter, the length of effective increase steel pipe in limited bulk up and down.In this way, before requirement of explosion proof is met
Put, make heater that there is higher power, realize heat distribution evenly, enhance defrost ability.Simultaneously by heater
Cold end is positioned over top, solves because heater heat is distributed not caused by all cold end designs of conventional steel heater side
Uniformly, the problem of defrost is bad.In discharge outlet position, steel pipe heater carries out bending, shortens heater heating position and discharge outlet
Distance, reduce discharge outlet risk of icing.Heater conductor is unilateral cabling, it is to avoid evaporator fin hurts the risk of wire,
