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.
