AN SEME-AUDIO DEFROSTER OF A COLD STORAGE ROOM

摘要

The present invention relates to a manual defroster for a refrigerator and a freezer having a header structure and, more particularly, to a manual defroster for a refrigerator and a freezer having a header structure, comprising: a mechanical part consisting of a compressor and condenser for conducting the physical transition of refrigerant circulating along a closed circuit; a cool air generating part for cooling or defrosting by applying low-temperature and low-pressure or high-temperature and high-pressure refrigerant generated by the mechanical part; and a control part including a group of opening and closing valves arranged at the fore-end and rear end of the cool air generating part and a pressure correction part arranged on a closed circuit for connecting the opening and closing valves so as to control the low-temperature and low-pressure or high-temperature and high-pressure refrigerant according to the mode of operation, wherein the cool air generating part and the opening and closing valves of the control part have two or more combinations and are composed in a parallel structure so as to conduct defrosting operation together with cooling operation. The present invention enables a user to control the application of the low-temperature and low-pressure refrigerant and the high-temperature and high-pressure refrigerant to the cool air generating part without movement by including a header structure part in the control part, thereby increasing operation efficiency because the control part has the header structure part for controlling the application of the low-temperature and low-pressure refrigerant and the high-temperature and high-pressure refrigerant so as to enable the user to manually manipulate the refrigerants without movement. The present invention reduces defrosting time by inhaling the pressure of the upper part of a high-pressure receiver into a freezing device and lowering the pressure of the receiver. And the present invention increases the efficiency of discharging ice by enabling the discharge of ice without the movement of stored refrigerated and frozen products because the present invention enables the collection of ice at one place and the discharge of the ice, which falls during defrosting operation, by further installing a defrosting tent in a refrigerator or a freezer.
