TECHNICAL FIELD The present invention relates to a refrigerator provided with a vegetable container.

2. Description of the Related Art A conventional example will be described with reference to FIG. 7. 1 is a refrigerator main body, 2 is a compressor for compressing a refrigerant, 3 is a condenser for condensing the refrigerant compressed by the compressor 2 at a predetermined temperature, Reference numeral 4 is a cooler for evaporating the condensed refrigerant at a predetermined temperature, 5 is a fan for blowing the cool air cooled by the cooler 4 into the refrigerator, 6 is a freezer compartment provided above the refrigerator body 1, and 7 is An upper storage room of a refrigerating room provided in the lower part of the refrigerator body 1, 8 is a lower storage room of the refrigerating room, and 9 and 10 are partition plates which divide the refrigerating room into an upper storage room 7 and a lower storage room 8. It is a partition. 13 is a vegetable container with an open upper surface for storing vegetables in the lower storage room 8,
14 is a lower storage compartment door that can be pulled out from the front, and 15 is a lower storage compartment door
The frame is fixed to 14 and holds the vegetable container 13. With the above structure, the freezing compartment 6 and the upper and lower storage compartments 7 and 8 are cooled to a predetermined temperature by the rotation of the refrigerating cycle constituted by the compressor 2, the condenser 3 and the cooler 4 and the fan 5. Here, paying attention to the lower storage compartment 8, the vegetable container 13 is cooled by the cold air sent from the upper storage compartment 7 from the rear part of the vegetable container 13 through the front part and the vegetables stored in the vegetable container 13. In order to prevent the dryness of the vegetables, that is, the evaporation of water, the barrier plate 9a provided at the rear part of the partition plate 9 so that the vegetables are not directly exposed to cold air.
Therefore, cold air is prevented from entering the vegetable container 13.

Problems to be Solved by the Invention However, according to the above-described configuration, the cooling of the vegetable container 13 is inefficient because cold air is passed around the vegetable container 13 to cool the inside of the vegetable container 13. Predetermined temperature Normal 4
In order to cool to -5 ° C, a large amount of cold air sent from the upper storage room and a strong wind speed were required. Due to this, cold air enters from the gap between the rear part of the vegetable container 13 and the blocking plate 9a of the partition plate 9 and both sides of the vegetable container 13,
There has been a problem that the transpirational water is carried away from the vegetables stored inside and the vegetables are dried in a short time. Further, since the amount of cold air for cooling the vegetable container 13 is large, there is a problem that the upper storage room 7 is too cold. Another vegetable container
Since the surroundings of 13 are extremely cooled, the water evaporated from the vegetables causes dew condensation on the inner surface of the vegetable container 13 and the lower surface of the partition plate 9, and the water droplets drop by weight and directly fall on the stored products such as vegetables. Further, it has a drawback that it stays on the bottom surface of the vegetable container 13 and comes into contact with vegetables to spoil stored materials.

In view of the above drawbacks, the present invention has an object to provide a refrigerator capable of drying stored items such as vegetables and preventing the stored items from spoiling due to dew condensation, and keeping the upper storage chamber and the lower storage chamber at a predetermined temperature. It is a thing.

Means for Solving the Problems In order to achieve the above object, the present invention is provided with a vegetable container that can be moved back and forth and a lid that substantially seals the upper surface of the vegetable container, and the lid is placed on the inner surface of the container. Is a water-permeable fiber and the outer surface is made of a hydrophobic resin thin film, and a moisture-permeable membrane is held by a resin flat plate with a large number of through-holes, and the refrigerator compartment is divided into upper and lower storage compartments. A space is provided between the plate and the lid, and a convex portion is formed on the front of the lid,
A notch portion that engages with this convex portion is provided on several flat plates having a bottom surface.

Action The present invention prevents the vegetables from drying by sealing the upper surface of the vegetable container with the lid by the above configuration and keeping the inside of the container high humidity by the water evaporated from vegetables, especially leafy vegetables, and between the lid and the partition plate. A cool air passage is provided in the room, a cool air passage to the upper storage room is secured, and the circulation of the cool air is smoothed so that the vegetable container can be cooled from the top of the vegetable container and the vegetable container can be maintained at a predetermined temperature with a small air volume. In this way, it is possible to prevent dew condensation in the vegetable container due to extreme cooling, and also to keep the humidity in the container constant with a moisture permeable film and to appropriately suppress the drying of the vegetables so that the vegetables can be stored for a long time. is there. Further, since the notch portion that engages with the convex portion of the front portion of the lid body is provided on the flat plate having the bottom surface of the middle partition, the lid body is fixed at the bottom surface of the middle partition,
It is installed at a position that reliably seals the upper surface of the vegetable container without moving backward or forward.

Embodiment One embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same parts as those of the related art are designated by the same reference numerals and the description thereof will be omitted.

16 is a partition plate and 17 is a middle partition. On the bottom surface of the middle partition 17, several flat plates 17b provided with notches 17a are formed. Reference numeral 18 denotes a lid body having a convex portion 18a formed on the front portion, and the inner box 1
It is held by the receiving portion 19a formed by 9, and the convex portion 18a of the lid body 18 is engaged with the notch portion 17a of the partition 17 to stop the movement of the lid body 18 in the front-rear direction to the upper surface of the vegetable container 20. It is fixed so as to be surely positioned, and is attached with a space from the partition plate 16. Further, the lid 18 has a large number of through holes 21a formed of resin.
And a moisture permeable membrane 22 welded to one surface of the flat plate 21. Here, the moisture permeable film 22 will be described. The moisture permeable membrane 22 is a laminate of a silicon thin film 22a and hydrophilic nylon fibers 22b, and the silicon thin film 22a has a thickness of about 10-50.
It consists of a group of almost amorphous reticulated molecules with a film thickness of about μ, and these cotton-like molecules completely shut out the liquid and have gas permeability due to the molecular spacing of 10 to 10 ³ Å. . That is, water vapor, air, and carbon dioxide gas are permeated if there is a difference in concentration inside and outside the membrane. Further, the reason why the hydrophilic nylon fiber 22b is used is to prevent dew condensation.

Because of the above-described structure, the lid 18 is positioned and closely attached to the upper surface of the vegetable container 20, there is no direct entry of cold air into the vegetable container 20, and vegetables are produced by the water evaporated from the vegetables stored in the vegetable container 20. The inside of the container 20 is kept at high humidity and the vegetables can be prevented from drying. Further, as shown in FIG. 6, the moisture permeable film 22 allows the moisture above the saturated humidity to hit the upper surface of the cool air well, and the moisture is apt to be cooled. Moisture vapor is gradually introduced as shown by the arrow. Therefore, the vegetable container 20
It is also possible to prevent an abnormal situation in which a large amount of vegetables are stored inside and the humidity inside the vegetable container 20 rises abnormally to cause dew condensation and the water droplets adhere to the vegetables to promote the spoilage of the vegetables. Further, since the vegetable container 20 is cooled from the entire circumference of the vegetable container 20, the scenery of the cold air from the upper storage chamber 7 is less than in the conventional case, and the vegetable container 20 can be cooled. There is no problem of being too cold, and dew condensation on the inner surface of the vegetable container 20 caused by extreme cooling is also eliminated.

Effect of the Invention As described above, the present invention provides a vegetable container by providing a lid body that is substantially in close contact with the upper surface of the vegetable container and flowing cold air between the lid body and the partition that divides the refrigerating chamber into the upper and lower storage chambers. It can be cooled from the entire circumference and can keep the inside of the vegetable container at a predetermined temperature with a small amount of air flow, it is possible to prevent dew condensation on the inner surface of the container caused by extreme cooling and the upper part which was emitted due to a large amount of cold air The problem of overcooling the storage room is also eliminated.

Also, in terms of structure, since the convex portion of the lid engages with the notch provided on the bottom surface of the partition, the lid is securely installed on the upper surface of the vegetable container and sealed so that no cold air directly enters the container. Moisture that evaporates from the vegetables stored inside keeps the inside of the container highly humid and prevents vegetables from drying, and the moisture permeable membrane keeps the optimum humidity constant to keep the vegetables fresh for a long time. You can Further, since the notch portion provided on the bottom surface of the intermediate partition is provided on the flat plate, the vegetable container can be kept at a low temperature without obstructing the flow of cold air for cooling the vegetable container.
