DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator provided with a vegetable room container.

[0002]

2. Description of the Related Art A conventional refrigerator is disclosed in Japanese Patent Laid-Open No. 62-2996.
One disclosed in Japanese Patent Publication No. 81 is known as an example. This conventional technique will be described with reference to FIG. In FIG. 5, a part of the cool air blown out from the upper cooler to the upper storage room is blown directly to the back of the vegetable room without cooling the upper storage room. In this structure, it is difficult to supply a sufficient amount of cold air to the front of the vegetable compartment, and the temperature tends to be uneven in the vegetable compartment. Therefore, if a large amount of cold air is supplied to the vegetable compartment in an attempt to cool it to a sufficiently low temperature to the front of the container, a large amount of cool air having a temperature of zero or less is blown from the cooler to the vegetable compartment, and the vicinity of the cold air blowout portion of the container is provided. Is excessively cooled locally and forms dew inside the part of the container, adversely affecting the vegetables stored in the container. In order to prevent this, a blocking plate was provided at the rear rear portion of the vegetable room. In addition, a moisture permeable membrane for keeping the humidity in the vegetable compartment at an appropriate level is formed integrally with the lid of the vegetable compartment, and when placed in a vegetable container, is sent from the upper storage compartment to a passage formed by the lid and a partition plate. It allows cold air to pass through.
The cool air sent from the upper storage room and hitting the blocking plate passed around the vegetable container and returned to the upper storage room through the front hole of the vegetable container.

[0003]

In the above-mentioned prior art, excessive cooling of the container due to a large amount of low-temperature cold air coming into contact with the container at the rear portion of the container in the vegetable compartment causes dew condensation on the container. In addition, if a blocking plate that blocks cold air is provided to solve this problem, the number of parts increases and the cost increases. In addition, since a space is provided between the container and the shielding plate so that the container does not touch the shielding plate, there is a problem that the inner volume of the vegetable container is reduced.

[0004] Further, although the lid substantially seals the vegetable compartment container, it cannot be perfect, and there is always a gap, so that the cool air sent from the upper storage compartment flows through the gap into the vegetable compartment container. There is a problem that water that evaporates from the vegetables stored in the vegetable room container and evaporates from the vegetables is carried away and dried.

An object of the present invention is to provide a refrigerator that minimizes drying in a storage room container.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to provide a partition member for dividing the inside of a refrigerator into a plurality of storage rooms, a cooler for cooling air in the storage room, and a cooling device for cooling the plurality of storage rooms. A refrigerator provided with a cool air passage for supplying the cooled air, wherein a storage container housed inside a first storage room among the plurality of storage rooms, a second storage room and the first storage room are provided. And a humidity control member provided on the storage container and facing the outside and the inside of the container.

Further, there is provided an outlet for blowing cool air from the cooler through the cool air passage to a storage room accommodating the storage container, and a cool air flow passage communicating the outlet with the ventilation hole. This is achieved because the humidity adjusting member faces the cold air flow path.

When the humidity adjusting member provided on the storage container faces a cold air passage through which the cool air flowing through another storage chamber flows, the water in the storage container that has become a predetermined amount or more is removed from the humidity adjusting member. Is added to the cool air after cooling in another storage room, for example, a refrigerating room, which is discharged into the cool air passage and called into the cool air passage by the action of (1). The cool air after cooling the refrigerating compartment is humid because it absorbs moisture in the refrigerating compartment, but becomes more humid. The cool air that cools the storage room container is a mixture of the cool air that is directly led from the cooler to the storage room and the cool air that has been cooled in the refrigerator room. Because it is overwhelmingly large, the humid cold air after cooling the refrigerator compartment is overwhelmingly large,
Mixed cold air is also humid. In addition, the space between the container and the lid is substantially closed, but cannot be completely closed.There is always a gap, but even if mixed cold air enters the container through this gap, the mixed cold air is humid. It does not dry the inside, and sometimes humidifies when the internal humidity is low.

To the bottom.

According to this embodiment, the vegetable compartment container 11 is cooled by the cool air after cooling the refrigerator compartment on the lid 14 side of the upper surface. Also, all the cool air that has cooled the inside of the vegetable compartment 10 is sucked into the cool air passage 17, and the cool air passage 17 is located in the lower front part of the vegetable compartment 10. 16a flows downward. Here, since the opening of the vegetable compartment of the cool air distribution duct 8 is located at the rear of the vegetable compartment, the cool air substantially after cooling the refrigerator flows on the rear wall side of the vegetable compartment container 11 at the upper rear part of the vegetable compartment container, Passage 16b
As it flows forward 〜16d, the proportion of cool air directly led from the cooler increases until it reaches a completely mixed and averaged temperature. Therefore, the cool air guided directly from the cooler to the vegetable room does not directly hit the vegetable room container 11, so that the vegetable room container 11 is extremely cooled, and power supply, freezing, etc. occur inside the vegetable room container 11. Is also gone.

Also, the cold air mixed and mixed is supplied to the vegetable compartment container 1 through a gap existing between the vegetable compartment container 11 and the lid 14.
1 and may cool the inside of the container, but the proportion of the mixed cold air is higher than that of the cool air directly introduced from the cooler, ie, the dry cold air, after cooling the refrigerator compartment and absorbing moisture. Since the cool air is overwhelmingly large, and the cool air after cooling in the refrigerator compartment passes through the cool air passage 15, the cool air passes through the vegetable compartment 11 by the function of the humidity control material 14 a and is discharged into the cool air passage 15. Since it is humid and contains moisture, even if it enters the interior of the vegetable compartment container 11, the rate of carrying moisture that evaporates from the vegetables and drying it is reduced.

That is, according to the present embodiment, a humidity control material is provided on a part of the lid provided at the upper part of the vegetable room container, and the humidity control material is provided in the cold air passage formed by the lid of the vegetable room container and the partition plate. The moisture released into the cool air passage by the action of the humidity control material is absorbed into the cool air after the cooling in the refrigerator compartment, which is drawn into the cool air passage, and then the cooler cools down to the rear of the vegetable compartment. , Directly,
The combined cool air is humid because it joins with the guided cool air. Therefore, even if the combined cool air that cools the vegetable compartment container penetrates into the interior through the gap between the vegetable compartment container and the lid, the rate of drying the inside is small. Furthermore, when the amount of vegetables and the like stored in the interior of the vegetable room is small, the result is that water is replenished, and freshness of the field can be maintained for a long time.
