Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a refrigerator, and in particular to a refrigerator, which is equipped with a plurality of storage chambers, each of which can be maintained at a different temperature, and the volume of each storage chamber can be changed. Regarding a refrigerator with movable shelves.

[Conventional technology]

Traditionally, this type of refrigerator has been underdeveloped.
Generally, the storage chambers are fixedly formed, such as a freezer compartment and a refrigerator compartment, and the food etc. stored in the storage compartments are maintained within a set temperature range by a built-in cooling device. It's just that.

[Problem that the invention attempts to solve]

Foods generally have different temperatures to maintain their freshness; for example, normal foods are frozen (-18℃).
(below), chilled (0°±2°C), and refrigerated (5°±2°C). Furthermore, since there are many types of foods and their amounts vary randomly, it is necessary to keep each food at the appropriate temperature as described above, depending on the amount. However, since the storage chamber inside the refrigerator is fixed, there is no flexibility in selecting temperature and storage volume, resulting in a problem of decreased efficiency and economy.

[Means for solving problems]

The refrigerator with movable shelves according to the present invention has a case surrounded by a heat insulating layer with a door that can be opened and closed on the opening surface, and a plurality of partition shelves that can be moved in parallel with the partition surface, and an inner wall of the heat insulating layer at the rear with a space between them. It has a plurality of storage chambers formed by a plurality of vertical partition plates, each of which is partitioned by a plurality of vertical partition plates, each of which is movable together with the partition shelf via a telescoping section, and the distance between the inner wall of the heat insulating layer is set to the storage chamber. A first duct separated and formed in a corresponding manner and a second duct formed inside the partition shelf form a wind circuit of the corresponding accommodation chamber, and each is inserted into the second duct. Each of the corresponding storage chambers is individually cooled through a separate evaporator.

[Effect]

According to the refrigerator with movable shelves according to the present invention, a plurality of storage chambers are each formed by a plurality of partition shelves that are movable in parallel to the partition surface and a vertical partition plate that is movable together with the partition shelves via an extendable part. Because of this, the volume of the containment chamber can be changed as needed. In addition, a wind circuit for cooling each storage chamber is formed by a first duct on the back side of each chamber and a second duct formed inside the partition shelf, and By arranging the evaporators in each duct, the plurality of storage chambers can be cooled separately to a desired temperature.
