Problems solved by technology

In particular, since the storage container has a large area to withstand the decompression pressure, in the case of forming the storage container with resin, it is necessary to thicken the storage container, thereby causing the food storage volume of the storage room to decrease. In addition, when the storage container is made of metal such as stainless steel, there is a problem of becoming an expensive storage container.

Abstract

The invention relates to a refrigerator capable of ensuring the food containing volume and reserving food for a long time with low cost. The refrigerator comprises: a refrigerator body (1) having a plurality of storage rooms; doors of the front openings of the storage rooms; a low pressure chamber (24) disposed in the storage rooms; and a decompression device for decompressing the low pressure chamber (24). The low pressure chamber (24) includes a low pressure chamber body (40) having an opening part (42a) for taking off or placing the food and a low pressure chamber door (50) for opening or closing the opening part (42a). The low pressure chamber body (40) has a box-shaped outer appearance (42) made of resin of the opening part (42a) for taking off or placing the food; and a metal sheet element (44) extending along multiple walls containing the bottom wall (42d) of the outer appearance (42).

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] As a conventional refrigerator technology, there is a technology disclosed in JP 2004-218924 A (Patent Document 1). In order to realize the long-term storage of food by controlling the air environment in the food storage room in a low-oxygen state to maintain the freshness of the refrigerator, a decompression storage space is independently set in the storage room, and the decompression storage space is discharged The air vacuum pump is installed in the corner of the storage room. The specific constitution is described below. [0003] In addition, the decompression storage space is formed by a low-pressure chamber made up of a storage container and a lid for storing and storing foods installed in the temperature conversion chamber. The storage container is installed between a pair of left and right support frames extending in the depth direction on the inner side of the doo...
