Refrigerator defrosting knife with serrated edge

Abstract

The invention discloses a refrigerator defrosting knife with a serrated edge, which mainly comprises a small knife body, a heating plate and a conductive wire, and is characterized in that the small knife body comprises a knife handle, a knife handle holder, a knife back and an edge, wherein a strip-shaped heating plate is mounted in the interlayer of the knife back, with two insulating strips respectively on two sides to allow the small knife body not to be electrified; the knife handle and the knife handle holder are made of non-conducting insulating materials; the heating plate is connected with the conductive wire which penetrates out of the knife handle from the center; the other end of the conductive wire is connected with a plug; once the plug is connected with a power, the heating is electrified and heated, and accordingly the temperature of the small knife body rises to about 200 DEG C, and the defrosting can be started. The small knife body adopts a serrated edge can quickly remove the frost on the inner wall of the refrigerator at a certain temperature, so that the purpose of labor saving and convenience are provided. Moreover, the defrosting knife is simple to manufacture, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to a living appliance, in particular to a serrated knife-edge refrigerator defrosting knife. Background technique [0002] After the refrigerator has been used for a period of time, the inside of the refrigerator will be covered with a lot of frost. Since most refrigerators do not have a defrosting device, defrosting is extremely troublesome. Some people even use fruit knives or kitchen knives to scrape it. Frost is very hard, if the force is small, it is difficult to remove, and if the force is too strong, it is easy to damage the refrigeration pipe or other things, causing unnecessary losses. There is a refrigerator defrosting knife whose patent No. is 201020629763X, because its blade is straight, although it is sharp, the speed of cutting frost is still relatively slow, and the effect is not ideal enough. Contents of the invention [0003] The object of the present invention is to provide a serrated knife-edge refrigerator d...
