BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a decompression chamber, and more particularly, to a refrigerator having a decompression chamber for facilitating production at low cost.

As is well known, a refrigerator is a device that stores food in a frozen state and / or a refrigerated state so that the food can be kept fresh longer.

The refrigerator includes a refrigerator body having a cooling chamber therein, a door for opening and closing the cooling chamber, and a refrigeration cycle device for providing cool air to the cooling chamber.

1 is a perspective view showing an example of a conventional refrigerator.

1, the refrigerator includes a refrigerator body 10 having a cooling chamber 20 therein and a cooling chamber door 30 for opening and closing the cooling chamber 20.

The cooling chamber 20 includes a freezing chamber 21 and a refrigerating chamber 22.

The cooling chamber door 30 includes a freezing chamber door 31 and a refrigerating chamber door 32 for opening and closing the freezing chamber 21 and the refrigerating chamber 22, respectively.

A plurality of shelves (41) for vertically dividing the refrigerating compartment (22) are provided in the refrigerating compartment (22).

A drawer (70) is provided in the refrigerating chamber (22).

Some of the drawers 70 contain vegetables and / or fruits therein to form a vegetable storage compartment 50.

However, in such a conventional refrigerator, since the inside of the refrigerating compartment 22 is relatively low in temperature, the vegetables or fruits stored in the vegetable storage compartment 50 may easily be worn (dried) and damaged .

In consideration of such a problem, some refrigerators have a sealing function including a case 60 opened on the front surface and a drawer 70 retractably housed in the case 60, as shown in FIG. 2 A vegetable storage room is provided.

The case 60 is formed as a rectangular parallelepiped having a front surface opened.

The outer surface of the case 60 is provided with a plurality of ribs 62 protruding outward. Thus, deformation of the case 60 can be suppressed.

A flange portion 63 extending outward is formed on the front surface of the case 60.

The drawer 70 includes a receiving portion 72 for storing food therein and a front portion 74 formed on the front surface of the receiving portion 72.

The first and second partial deformation restraining parts 301 and 305 may be formed with a female threaded part 165 so that the fastening member 260 can be screwed.

The front face portion 174 of the drawer 170 may be pressed toward the case 150 when the case 150 is to be housed in the case 150. [

When the drawer 170 is moved to the inside of the case 150 and stored therein, the sealing member 180 is brought into contact with and pressed against the flange 154 and the hook 211 and the hook 193 So that the sealed state can be maintained.

When the drawer 170 is completely stored, the interior of the drawer 170 can be decompressed to a pressure lower than the atmospheric pressure by the decompressor 183. At this time, deformation of the opening region of the case 150, which is relatively weak in strength, can be suppressed by the deformation suppressing members 290, 300.

When the drawer 170 is to be drawn out, the operating member 230 is held and pulled forward. When the operating member 230 is pulled, the operating member 230 is rotated about the rotating shaft 234, and the operating bar 240 can be moved to the releasing position by the pressing portion 235.

The operating bar 240 presses the opening and closing member 251 to open the communication part 250 and presses the hook 211 to release the engagement of the hook 211 and the engaging part 193 have.

When the operating member 230 is continuously pulled forward, the drawer 170 can be pulled forward.

The foregoing has been shown and described with respect to specific embodiments of the invention. However, the present invention may be embodied in various forms without departing from the spirit or essential characteristics thereof, so that the above-described embodiments should not be limited by the details of the detailed description.

Further, even when the embodiments not listed in the detailed description have been described, it should be interpreted broadly within the scope of the technical idea defined in the appended claims.
