Anti-frost evaporator pipe of drawer type refrigerator

Abstract

The present invention relates to an anti-frost evaporator pipe of a drawer type refrigerator for preventing frost from being formed on a ceiling portion of a storage chamber of the refrigerator. It is an object of the present invention to provide an anti-frost evaporator pipe of a drawer type refrigerator, wherein by preventing frost from being formed on a ceiling surface of an inner case through a structural improvement in the evaporator pipe installed to the inner case, excessive cooling and spoilage of foods and food damage due to the conversion of frost into water can be prevented and a drawer container can be more smoothly opened or closed, and wherein more precise operating conditions can be set and temperature variation in the storage chamber cannot be produced by using a sensor installed to more accurately detect a status of the storage chamber. To achieve the aforementioned object of the present invention, there is provided an anti-frost evaporator pipe of a drawer type refrigerator including an inner case in which a storage chamber for accommodating a storage drawer container is defined and the storage drawer container is kept at a low temperature by means of the evaporator pipe for refrigerant circulation wrapped around the exterior of the inner case, the evaporator pipe comprising curved pipe portions positioned at both side surfaces of the inner case, and a straight pipe portion positioned at a top surface of the inner case and connected with the curved pipe portions.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an evaporator pipe of a drawer type refrigerator, and more particularly, to an anti-frost evaporator pipe of a drawer type refrigerator, wherein the structure of the evaporator pipe is improved to prevent formation of frost on a ceiling portion of a storage chamber of the refrigerator, and an operating state of the refrigerator can be more accurately controlled by more accurately detecting the status of the interior of the storage chamber. [0003] 2. Description of the Related Art [0004] Generally, a refrigerator is to prolong a preservation term of a food by means of circulation of a refrigerant therethrough. Recently, various refrigerators have been developed according to their uses. For such specialized purposes, refrigerators that enable easy storage of foods and have a food-ripening function have been developed. [0005] According to door-opening methods, such refrigerators are cla...

Benefits of technology

[0020] The present invention is conceived to solve the aforementioned problems in the prior art. Accordingly, an object of the present invention is to provide an anti-frost evaporator pipe of a drawer type refrigerator, wherein by preventing frost from being formed on a ceiling surface of an inner case through a structural improvement in the evaporator pipe installed to the inner case, excessive cooling and spoilage of foods and food damage due to the conversion of frost into water can be prevented and a drawer container can be more smoothly opened or closed, and wherein more precise operating conditions can be set and temperature variation in a storage chamber cannot be produced by using a sensor installed to more accurately detect a status of the storage chamber.

Problems solved by technology

Furthermore, since the frost formed on the ceiling surface of the inner case 30 prevents heat transfer into the inner case and thus reduces thermal efficiency of the refrigerator, it is necessary to remove the frost.

Therefore, the foods stored in the drawer container 40 are damaged and spoiled.

These problems are due to the frost formed on the surfaces of the inner case 30.
