Description

refrigerator

The present invention relates to a refrigerator having a prefabricated inner case with an improved seating structure of a hot pipe.

A refrigerator is a device that keeps food fresh by including a main body having a storage compartment and a cold air supply system for supplying cold air to the storage compartment. The storage compartment includes a refrigerating compartment maintained at approximately 0 to 5 degrees Celsius to refrigerate food, and a freezer compartment maintained at approximately 0 to 30 degrees Celsius to freeze and store food.

The main body of the refrigerator is provided by combining an inner case and an outer case. The inner case forms a storage compartment, and the outer case forms the exterior of the refrigerator. A heat insulating material for heat insulation is disposed between the inner and outer wounds. The storage compartment of the refrigerator is provided so that the front is opened, and the open front is closed by a door to maintain the temperature of the storage compartment.

In general, the inner chamber of a refrigerator heats a sheet of resin material, places the stretched sheet on a mold, sucks in air from the opposite side of the mold, and the heated sheet is heated on the mold or sucked into the mold by the suction force. It is formed by a vacuum forming method in which it is formed by allowing it to enter.

When the refrigerator is operated, cold air inside the storage compartment is introduced into the outer box forming the exterior of the main body, and dew may form on the outer surface of the outer box due to a temperature difference between the inside and the outside of the outer box. To prevent this, a hot pipe is installed on the front edge of the inner box to prevent dew formation on the outer box. For the hot pipe to be seated, a seating groove is formed on the front edge of the inner box.

As the hot pipe seated in the seating groove closely adheres to the outer skin, the high-temperature heat by the high-temperature refrigerant flowing inside the hot pipe is well transferred to the outer skin. It is possible to prevent dew forming on the outer surface of the outer box.

In addition, as the hot pipe seated in the seating groove moves away from the storage room, the transfer of high-temperature heat flowing into the hot pipe to the inside of the storage room is reduced, reducing the rise of the temperature inside the storage room and consuming energy to lower the temperature inside the storage room. can be reduced.

Since the inner case is formed by a vacuum forming method, a separate part must be used for the seating groove in order to bring the hot pipe into close contact with the outer case and away from the storage compartment.

One aspect of the present invention provides a refrigerator in which a rib is integrally formed with an outer case so that a hot pipe seated in a seating groove formed in a front flange of a prefabricated inner case is in close contact with an outer case.

The plurality of first ribs may allow the hot pipe to come into close contact with the external trauma located in front of the internal trauma.

The hot pipe is in close contact with the trauma by the plurality of first ribs, and the temperature difference between the inside and outside of the trauma is reduced by the high-temperature heat generated by the high-temperature refrigerant flowing into the hot pipe, which is generated on the outer surface of the trauma. Condensation can be prevented.

The plurality of second ribs may be formed on a side surface close to the storage compartment among both sides of the inside of the seating groove.

The plurality of second ribs may allow the hot pipe to come into close contact with the external trauma located on the side of the internal trauma.

The hot pipe is in close contact with the trauma by the plurality of second ribs, and the temperature difference between the inside and outside of the trauma is reduced by the high-temperature heat generated by the high-temperature refrigerant flowing into the hot pipe, which is generated on the outer surface of the trauma. Condensation can be prevented.

The plurality of second ribs may allow the hot pipe to move away from the inside of the storage compartment.

The hot pipe is disposed far from the inside of the storage compartment by the plurality of second ribs, so that transfer of high-temperature heat by the high-temperature refrigerant flowing into the hot pipe to the inside of the storage compartment may be reduced.

Among the seating grooves, the plurality of ribs provided in the seating groove provided on the front flange of the lower plate may be formed on a bottom surface inside the seating groove.
