Description

Refrigerator and Freezer Shelf {REFRIGERATOR AND SHELF FOR REFRIGERATOR}

The present invention relates to a refrigerator and a shelf for a refrigerator.

The refrigerator is a device for low temperature storage of food, and may be configured to freeze or refrigerate food according to the type of food to be stored. To this end, the refrigerator may include a cold air supply device in which a cooling cycle is implemented. The cold air supply device is configured such that the refrigerant undergoes a process of compression-condensation-expansion-evaporation, and cool air is generated as the refrigerant circulates through a cooling cycle. The cold air generated in the evaporator of the cold air supply device is supplied to the storage space of the refrigerator, and as the cold air supplied to the storage space of the refrigerator is circulated by convection, the food inside the refrigerator may be stored under the required temperature conditions. In general, the main body of the refrigerator has a rectangular parallelepiped shape with an open front surface, and a refrigerating chamber and a freezing chamber are provided inside the main body. The front surface of the main body is provided with a refrigerator compartment door and a freezer compartment door for selectively shielding the opening.

These refrigerators have a top mount type in which the freezer is disposed above the refrigerating chamber and a bottom freezer type in which the freezer is disposed below the refrigerator. And, the freezer compartment and the refrigerating compartment may be divided into a side by side type (Side By Side-Type) disposed in both sides.

On the other hand, the user has no choice but to open the refrigerating compartment door or the freezing compartment door in order to take out the food stored in the refrigerator, whereby hot air outside the refrigerator is introduced into the refrigerating compartment or the freezing compartment. Outside air supplied from the outside causes the temperature inside the refrigerator to rise, and a cold air supply device must be operated to maintain an appropriate temperature.

The cold air supplied through the cold air supply device may be discharged through the multi duct provided on the rear wall of the refrigerator to circulate the internal space of the refrigerating compartment. However, since the multi-duct of the conventional refrigerating compartment which is configured and functions as described above, cold air is always discharged at a constant position regardless of the position of food stored in the refrigerating compartment, there is a problem in that cold air supply is not efficient.

In addition, since the cold air is supplied only from the cold air outlet of the multi duct, there is a disadvantage in that it takes a long time to supply cold air to the entire inside of the refrigerator.
