Specialty room of the refrigerator

The present invention relates to a specialty room of a refrigerator, and more particularly, to a specialty room of a refrigerator, which prevents cold air from leaking out of the specialty room and prevents noise generated by inserting and removing shelves.

The refrigerator utilizes a principle that heat exchange is performed by using a temperature difference generated when the refrigerant is phase-changed in the process of compressing, condensing, or expanding a refrigerant such as freon or methane, and is a device that allows food to be kept fresh.

Such a refrigerator is generally a storage compartment having an open front in a main body constituting an outer body, and a freezer compartment and a refrigerating compartment are partitioned, and a door that opens and closes the freezer compartment and a refrigerating compartment is hinged to a main body front portion.

In the freezer and the refrigerating chamber, a plurality of shelves are interposed to accommodate food. In recent years, a separate temperature zone is maintained to provide an optimal temperature according to the type of food. There is space.

For example, a vegetable compartment provided in the lower side of the refrigerating compartment in the form of a drawer and formed to preserve vegetables and fruits, and a special selection chamber formed at the upper side of the refrigerating compartment to store fish and foods that require freshness in particular.

Usually, a freezer compartment of a domestic refrigerator generally maintains a temperature range of -12 ° C to -24 ° C, and the refrigerating chamber is generally user adjustable to maintain a temperature range of 0 ° C to 7 ° C.

In addition, the vegetable chamber should normally maintain a temperature range of 5 ° C to 10 ° C, and the specialty chamber should maintain a temperature range of about 1 ° C.
