Problems solved by technology

As a result, the surface of the piping 40 installed in the vicinity of the defrosting heater 37 also rises to approximately 100° C. or higher. Therefore, in order to prevent deformation due to heat, it is necessary to cover the surface and other parts with metal such as aluminum foil, resulting in material costs and man-hours. The problem of rising costs

Abstract

Cooler (107) provided on the back surface side of a refrigerator, the cooler for generating cool air, defrosting heater (132) provided below cooler (107), and cooler cover (120) having cool air return port (135) are provided. Center of defrosting heater (132) is set on the upper side of a lower surface of a freezing compartment, projection member (136) protruding into the interior side is arranged on the lower surface of the freezing compartment, and a lower end of cool air return port (135) and an upper end of projection member (136) are overlapped with each other in the height direction.

Description

technical field [0001] The present invention relates to a refrigerator provided with a defrosting heater. Background technique [0002] In recent years, with the development of energy saving in refrigerators, in order to reduce the power consumption of refrigerators, in order to improve the cooling efficiency, the efficiency of the compressor with a large input has been improved, and the frost attached to the cooler has been melted. The method of improving the defrosting efficiency. [0003] Among them, as a conventional refrigerator that reduces power consumption of the refrigerator, a refrigerator that reduces ventilation resistance of a cooling air path and increases cooling air volume to improve cooling efficiency is disclosed (for example, refer to Patent Document 1). Moreover, the refrigerator which promotes heat convection at the time of defrosting is also disclosed (for example, refer patent document 2). [0004] Hereinafter, the above-mentioned conventional refrig...
