Description

Refrigerator {refrigerator}

The present invention relates to a refrigerator equipped with a vacuum chamber capable of storing foods for a long period of time or freshly stored.

Generally, a compressor forms a refrigeration cycle together with a condenser and an evaporator, and is widely used in a conventional refrigerator including a air conditioner and a kimchi refrigerator which is actively used recently.

At least one storage compartment is formed in the upper part of the Kimchi refrigerator, and a machine room for operating the Kimchi refrigerator is formed in the lower part of the kimchi refrigerator.

A plurality of storage containers are housed in the storage room to store food, and a compressor, a condenser, a cooling fan, and the like are installed in the machine room.

Among the devices installed in the machine room, the compressor is usually installed on the bottom of the machine room, compresses the refrigerant at high temperature and high pressure, and supplies the compressed refrigerant to each device installed in the kimchi refrigerator, thereby performing a cooling operation according to the refrigeration cycle.

In a typical refrigerator, a storage room such as a freezing room or a refrigerating room is provided, and the food stored in the storage room is frozen or stored at a low temperature for a long period of time by using cold air generated by the refrigeration cycle.

Generally, a refrigerator is classified into a direct cooling type and a indirect cooling type according to a method of cooling air in a storage room.

In the direct cooling type refrigerator, an evaporator is installed in a storage room, and the air in the storage room is directly cooled through an evaporator. In an indirect cooling type refrigerator, an evaporator and a blowing fan are installed in a storage room, Is indirectly cooled.
