Description

Refrigerator with Specialty Rooms {REFRIGERATOR WITH SPECIAL-REFRIGERATION-ROOM}

The present invention relates to a refrigerator provided with a special selection room, and more particularly, the configuration is simple, making it easy to manufacture and preventing unnecessary increase in the installation space, and having a relatively wide cooling temperature range. The present invention relates to a refrigerator equipped with a special chamber for adjusting the cooling temperature according to the cooling characteristics of food.

In general, a refrigerator is a device for low temperature storage of food, and includes a freezer compartment for freezing and storing food at a relatively low temperature and a refrigerating compartment for storing food at a relatively high temperature. The freezing chamber usually maintains a cooling temperature of -18 ° C or lower, and the refrigerating chamber has a cooling temperature range around 2 ° C.

Fish and meat (漁 肉類) is usually stored in the freezer, in which case it takes a lot of time to thaw, causing a lot of inconvenience, especially if you want to store meat for a relatively short time, for example several hours to several ten hours There is no place for proper storage.

In recent years, in consideration of this point, refrigerators have been devised to store fish, meat, and the like by providing a special special room called a fresh room or a singso, etc. inside the refrigerating compartment.

By the way, in the conventional refrigerator equipped with the special selection room, the configuration of the special selection room is complicated, making it difficult to manufacture, and also requires a relatively large installation space compared to the storage space, there is a problem that the content is reduced.

In addition, since the cooling temperature is fixed around -1 ℃, it is not suitable for storage of other foods except for fish meat, and if the fish meat is not stored, the special chamber is left empty, so that the space utilization of the refrigerating chamber is insufficient. have.

In addition, such a conventional specialty room usually has a cooling temperature range of about -1 ° C., and when meat and the like are stored, water in the cells repeatedly freezes and thaws, thereby hampering the unique flavor of food. have.

Therefore, the object of the present invention is not only to suppress the unnecessary increase in the installation space due to its simple configuration, but also to control the cooling temperature appropriately according to the cooling characteristics of the food by having a relatively wide cooling temperature range. It is to provide a refrigerator equipped with a special room.
