Description

Condenser for refrigerator cooled by defrost water {THE CONDENSER COOLED BY DEICED WATER FOR REFRIGERATOR}

The present invention relates to a condenser for refrigerators cooled by defrost water, and more particularly to a condenser for refrigerators having a structure in which the heat of condensation is easily dissipated by defrost water generated when ice or frost layers of the freezer are defrosted. It is about.

Generally, a refrigerator includes a compressor, a condenser, an expansion valve, and an evaporator connected to each other through a refrigerant pipe, and the refrigerant is compressed, condensed, expanded, and evaporated by the respective devices as the refrigerant flows through the refrigerant pipe, thereby absorbing heat inside the refrigerator. Release to the outside.

The condenser is installed on the outside of the refrigerator to facilitate heat dissipation, and the evaporator is installed on the inside of the refrigerator to facilitate heat absorption inside the refrigerator. In addition, in the combined refrigerator freezer, in consideration of its cooling performance and power consumption, an evaporator is usually installed on the freezer compartment side, and the air cooled by the evaporator is transferred to the refrigerating compartment side so that the refrigerated compartment maintains a low temperature state.

However, since the freezing chamber is at a low temperature of approximately 10 degrees to 30 degrees, the moisture particles adhere to the surface of the cooling pipe provided on the freezing chamber side to form a frost layer. As the frost layer is opened or closed in the freezer compartment or air flows into the freezer compartment by air flow, the moisture is continuously introduced into the freezer compartment and stacked more thickly. In addition, the frost layer has a problem that the cooling performance of the refrigerator is deteriorated by changing to a hard ice layer over time to prevent heat exchange through the cooling pipe.

In order to solve this problem, conventionally, a defrosting device for stopping a refrigerator for a predetermined time or heating a refrigerant pipe is provided to remove an ice layer.

1 shows a schematic configuration of a conventional refrigerator, in which an evaporator 1 is installed inside a refrigerator freezer compartment and a heater 3 is provided below the evaporator. In addition, a collecting container 4 is installed at the lower part of the evaporator 1 to collect defrost water generated by melting the frost or ice layer attached to the evaporator 1 by the heater 3. At this time, the collected defrost water is connected to the pipe (6) is accommodated in the water collecting container (5) installed in the lower part of the refrigerator. In addition, the condenser (2) is typically bent by the support tube is the refrigerant pipe passing through the refrigerant, and is exposed to the outside to the rear side of the refrigerator to discharge the heat of the freezer compartment absorbed by the evaporator (1) to the outside of the refrigerator. Is installed. The collecting container 5 in the lower part of the refrigerator is installed at the lower end side of the condenser 2 so that the defrost water contained therein is in contact with the condenser 2 and is easily discharged from the condenser.

Therefore, when the heater 3 is operated to remove the ice layer of the evaporator, the ice layer melts and defrost water is generated, and the defrost water is collected in the sump 4 installed below the evaporator 1 and condensers along the pipe 6. (2) The water is collected by a water collecting container 6 provided at the lower portion. When the defrost water is collected in the water collecting vessel 6 and the condenser lower end part is submerged, the heat of the condenser 2 is absorbed by the defrost water in the low temperature state and is heat-dissipated.

However, the condenser of the refrigerator as described above has a problem that the heat dissipation is easy only when the lower end is submerged in the defrost water contained in the collecting container, so that the lower part of the condenser is not cooled by the defrost water.

Accordingly, an object of the present invention is to provide a condenser for a refrigerator having a structure capable of cooling even a small amount of defrost water and improving a refrigerator performance.
