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.

Embodiment Construction

[0064] Hereinafter, a refrigerator according to an embodiment of the present invention will be described using the drawings.

[0065] First, refer to Figure 1 ~ Figure 3 The whole refrigerator is explained. figure 1 Is a front view of the refrigerator of this embodiment, figure 2 Yes figure 1 The central longitudinal sectional view of the refrigerator, image 3 Yes figure 1 Front view of the main body of the refrigerator.

[0066] The refrigerator includes a refrigerator main body 1 and doors 6-10. The refrigerator main body 1 is configured by having a urethane foam heat insulating material 13 and a vacuum heat insulating material (not shown) between an outer box 11 made of a steel plate and an inner box 12 made of resin, and has a refrigerator compartment 2 in order from above. Freezer compartments 3 and 4 and vegetable compartment 5 and other storage compartments. In other words, the refrigerating compartment 2 is divided and arranged at the uppermost stage, the vegetable c...

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 invention relates to a refrigerator. Background technique [0002] As a technique of a conventional refrigerator, there is a technique disclosed in JP 2004-218924 A (Patent Document 1). In order to achieve long-term storage of food by controlling the air environment in the food storage room to maintain freshness while keeping the air environment in a low-oxygen state, the refrigerator has an independent pressure-reduced storage space in the storage room and discharges it into the reduced-pressure storage space The vacuum pump of the air is installed in the corner of the storage room. The specific structure is described below. [0003] In addition, the reduced-pressure storage space is formed by a low-pressure chamber composed 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 ...
