Abstract
A refrigerator according to the present invention is so designed that the refrigerating chamber is divided by a partition plate into an upper cooling chamber and a lower cooling chamber in which a vegetable storing container in a sealed structure is accommodated, the vegetable storing container having a lid member attached with a humidity permeable film of gas permeability, whereby the humidity inside the vegetable storing container is maintained within a predetermined range suitable for preservation of vegetables, such that the vegetables are prevented from being dried to be withered and can be kept fresh for relatively a long period of time.
Claims15
A refrigerator comprising:
- a refrigerating chamber;
- a partition plate in said refrigerating chamber for dividing said refrigerating chamber into an upper cooling chamber and a lower cooling chamber;
- a vegetable storing container including a container main body having an upper opening at the upper surface thereof, a lid member covering said upper opening of said container main body, said lid member being a synthetic resin flat plate having a plurality of through-holes, a gas-permeable humidity-permeable film attached to said flat plate for covering said through-holes, and said vegetable storing container being accommodated within said lower cooling chamber;
- and
- a cold air convection path defined between said lid member and said partition plate for fluidly communicating said container main body of said vegetable storing container with said upper cooling chamber.

A refrigerator comprising:
- a refrigerating chamber;
- a partition plate in said refrigerating chamber for dividing said refrigerating chamber into an upper cooling chamber and a lower cooling chamber;
- a vegetable storing container including a container main body having an upper opening at the upper surface thereof, a lid member covering said upper opening of said container main body, said lid member including a humidity-permeable film having gas permeability for allowing gases through said lid member, and said vegetable storing container being accommodated within said lower cooling chamber;
- and
- a cold air convection path defined between said lid member having said humidity-permeable film and said partition plate, and being defined between said vegetable storing container and an inner wall of said lower cooling chamber, for fluidly communicating said vegetable storing container and said lower cooling chamber with said upper cooling chamber.

A refrigerator which comprises:
- a refrigerating chamber divided into an upper cooling chamber and a lower cooling chamber by a partition member;
- a cold air take-in port provided in the rear of said partition member so as to communicate said upper cooling chamber with said lower cooling chamber;
- a cold air returning port provided in the front of said partition member so as to communicate said upper cooling chamber with said lower cooling chamber;
- a vegetable storing container accommodated in said lower cooling chamber and including a container main body opened at the upper surface thereof, and a lid member covering said upper opening of the main body, said lid member being provided with a humidity permeable film having gas permeability;
- a first cold air convection path defined between said lid member and said partition member so as to run from said cold air take-in port to said cold air returning port;
- and
- a second cold air convection path defined between said container main body and the inner wall of said lower cooling chamber from said cold air take-in port, along the rear surface, bottom surface and front surface of said container main body, to said cold air returning port.

A refrigerator which comprises:
- a refrigerator main body consisting of an outer box, an inner box and an adiabatic material filled between the outer and the inner boxes;
- a refrigerating chamber composed of said inner box and opened at the front surface thereof;
- an upper cooling chamber divided from a lower cooling chamber by a partition member in said refrigerating chamber;
- a door member which closes said opening in the front surface of said upper and lower cooling chambers in a freely openable manner;
- a support frame held at one end thereof on the rear surface of said door member closing the front opening of said lower cooling chamber, and guided by a support device in a manner to be freely drawn in or out, said support device being provided at the opposite side walls of the inner box forming said lower cooling chamber;
- a container main body for preserving vegetables therein which is opened at the upper surface thereof and mounted on said support frame so as to be drawn into or out of the refrigerator in association with the closing or opening of the door member;
- a lid member provided with a humidity permeable film having gas permeability for covering said upper opening of the container main body;
- a cold air take-in port formed in the rear portion of said partition member so as to communicate said upper cooling chamber with said lower cooling chamber;
- a cold air returning port formed in the front portion of said partition member so as to communicate said upper cooling chamber with said lower cooling chamber;
- a first cold air convection path defined between said lid member and said partition member and running from said cold air take-in port to said cold air returning port;
- a second cold air convection path defined between said container main body and said inner box forming said lower cooling chamber and running from said cold air take-in port to said cold air returning port along the rear surface, the bottom surface and the front surface of said container main body;
- and
- a covering member placed in said second convection path adjacent to said cold air take-in port so as to cover the rear surface of said container main body.
