Embodiment Construction

[0018] An embodiment of the present invention will be specifically described below with reference to the drawings.

[0019] figure 1 It is a cross-sectional view of a refrigerator with a refrigeration cycle. The refrigerator 2 comprises a refrigerator body 1 and doors 3 to 5 to form storage rooms (inside the refrigerator) 10 to 11 for storing food and the like. The storage rooms 10 to 12 are usually in a hermetically sealed state by closing the doors 3 to 5 . And each store room 10-12 is communicated by the cool air duct. The refrigerator body 1 is made of an outer box, a heat insulating material and an inner box. Refrigerator door 3, vegetable compartment door 4, freezer compartment door 5 are installed in the front of refrigerator body 1, form refrigerator compartment 10, vegetable compartment 11, freezer compartment 12.

[0020] The refrigerator 2 includes a refrigeration cycle, a cooling fan 8, an electric regulator 9, and the like in order to cool the inside of the r...

Abstract

An evaporator of a refrigeration cycle uses a combustible refrigerant. A defrosting heater is installed in the vicinity of the evaporator. The defrosting heater includes a heater wire(14) formed of a metal resistant element, an inner glass pipe(15) containing the heater wire, and an outer metal pipe(16) covering the outside of the inner glass pipe for forming a space between the inner glass pipe and the outer metal pipe. When the heater wire generates heat, a surface temperature of the outer metal pipe reaches a temperature below an ignition point of the combustible refrigerant.

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a refrigerator equipped with a refrigeration cycle using flammable refrigerants. Background technique [0002] In general, the structure of a refrigerator is that the refrigerant passing through the evaporator of the refrigerating cycle obtains heat from the air in contact with the surface of the evaporator and evaporates, so the cooled air is sent to the refrigerator as cold air by a circulating fan. In the refrigerator. When the evaporator gets heat from the air around the evaporator to cool the inside of the refrigerator, frost will form on the surface of the evaporator during operation. Therefore, the structure is such that a glass tube heater for defrosting is provided below the evaporator, and frost adhering to the evaporator is melted and removed by the radiant heat of the glass tube heater for defrosting. [0003] HFC-based refrigerants have been used as refrigerants for such r...
