Description

[Detailed description of the invention] Industrial applications The present invention relates to a refrigerator equipped with a vegetable container.

Conventional technology A conventional example will be explained based on FIG. 6. 1 is a refrigerator body, 2 is a compressor that compresses the cold bracken, and 3 is a condenser that condenses the refrigerant compressed by the compressor 2 at a predetermined temperature. , 4 is a cooler for evaporating condensed refrigerant at a predetermined temperature, and 5 is a fan for blowing cold air cooled by the cooler 4 into the refrigerator. 6 is a freezer compartment provided in the upper part of the refrigerator main body 1, 7 is an upper storage compartment of a refrigerator compartment provided in the lower part of the refrigerator main body 1, 8 is a lower storage compartment of the refrigerator compartment, and 9 and 10 are the These are a partition plate and a middle partition that divide the refrigerating room into an upper storage chamber 7 and a lower storage chamber 8. 11 is an upper storage chamber door; 12 is a vegetable container with an open top for storing vegetables and the like in the lower storage chamber 8; 13 is a lower storage chamber door that can be pulled out from the front; and 14 is a lower storage chamber door 13. This is a frame that is fixed to and holds the vegetable container 12. With the above configuration, the compressor 2. Condenser 3. The freezer compartment 6 and the upper and lower storage compartments 7 and 8 are cooled to a predetermined temperature by the refrigerant cycle constituted by the cooler 4 and the rotation of the fan 5. Now, paying attention to the lower storage chamber 8, the vegetable container 12 is cooled by cold air sent from the upper storage chamber 7 through the front part from the rear of the vegetable container 12. In order to prevent vegetables, etc. from drying out, that is, from evaporating moisture, a cutoff root 9a provided at the rear of the partition plate 9 is provided to prevent cold air from entering the vegetable container so as to prevent cold air from directly hitting the vegetables, etc. Ta.

Problems to be Solved by the Invention However, according to the above-described configuration, cooling of the vegetable container 12 is inefficient because cold air is passed around the vegetable container 12, and the inside of the vegetable container 12 is cooled. In order to cool the air to a predetermined temperature, usually 4° C. to 5° C., a large amount of cold air sent from the upper storage chamber and a strong wind speed are required.

From this, the new version 9 of the rear part of the vegetable container 12 and the partition plate 9
A problem has arisen in that cold air enters from the gap between the vegetable container 12 and the vegetable container 12, and the water that evaporates from the vegetables stored in the vegetable container 12 is carried away and the vegetables become dry in a short period of time. The amount of cold air still cooling the vegetable container 12 increases, so the upper storage chamber 7 may become too cold or the vegetable container 1 may become too cold.
2, the moisture evaporating from the vegetables causes condensation to form on the inner surface of the vegetable container 12 and the lower surface of the partition plate 9, and these water droplets fall directly onto the vegetables, etc. This has the disadvantage that the bottom surface of the vegetable container 12 comes into contact with vegetables and the like, causing them to rot.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a refrigerator that can prevent vegetables from drying out and rotting due to condensation, and can maintain a predetermined temperature in an upper storage chamber and a lower storage chamber.

Means for Solving the Problems In order to achieve this object, the refrigerator of the present invention includes a vegetable container that is movable back and forth, a moisture permeable membrane that can cover the opening of the vegetable container so as to be openable and closable, and the moisture permeable membrane. It consists of a roll that winds up.

Effects According to the present invention, the opening on the top surface of the vegetable container is covered with a moisture-permeable membrane, which blocks the cold air passing through the top surface of the vegetable container and the vegetable container, and keeps the inside of the container at a certain level due to the moisture evaporated from the vegetables. By maintaining high humidity, drying of vegetables, etc. is moderately suppressed, and vegetables, etc. can be stored for a long period of time.

EXAMPLE An example of the present invention will be described below with reference to the drawings. Note that the same parts as those in the prior art are given the same numbers, and detailed explanation thereof will be omitted.

15 is a partition plate, and 16 is a middle partition. Page 175 shows a vegetable container, in which the flange portion of the vegetable container 17 is curved vertically from the front to the rear of the top opening, and the flange portion of the vegetable container 17 is fitted with a soft resin gasket. has been inserted.

Reference numeral 19 denotes a moisture permeable membrane that covers the upper opening of the vegetable container 17. The moisture permeable membrane 19 is wound around a roll 21 in a case 20 attached to the front side of the partition plate 15, and a holder 22 having a rectangular cross section is detachably attached to the tip of the moisture permeable membrane 19. It is attached to. Also, rubber 23 is attached to both ends of the roll 21 that winds up the moisture permeable membrane 19 in the case 2o.
It is designed to be caught on a hook 24 inside. As a result, the moisture permeable membrane 19 is always pulled toward the case 20, so that when the lower storage chamber door 13 is pulled out, the moisture permeable membrane 19 is wound around the roll 21. Therefore, the moisture permeable membrane 19 is pulled out and the vegetable container 17
By locking the holder 22 at the rear upper end of the container and by covering the gasket 18 with the moisture permeable membrane 19, the upper opening of the vegetable container 17 is covered with the moisture permeable membrane 19, A closed chamber is formed.

Here, the moisture permeable membrane 19 will be explained. The moisture permeable membrane 1
9 is a silicon thin film 19a and a hydrophilic nylon fiber 19b
The silicon thin film 19a has a thickness of about 10 to 50
It is composed of mostly amorphous chain-like molecular aggregates with a film thickness of about μm, and these cotton-like molecular aggregates completely shut out liquid, and have gas permeability due to the molecular spacing of 10 to 10'A. It is. In other words, water vapor, air, and carbon dioxide gas can permeate through the membrane if there is a difference in concentration between the inside and outside of the membrane. Moreover, the reason for using the hydrophilic nylon fiber 19b is to prevent dew condensation. and the moisture permeable membrane 1
Since the membrane 9 is knitted from hydrophilic nylon fibers, peeling from the ends and misalignment of the fibers occur.In order to prevent this, a melted part 19c is provided around the moisture permeable membrane 19.

With the above configuration, the moisture permeable membrane 19 is in close contact with the gasket 18 on the upper surface of the vegetable container 17,
There is no direct or direct intrusion of cold air into the vegetable container 17, and the moisture evaporated from the vegetables stored in the vegetable container 17 keeps the inside of the vegetable container 17 at a high level of humidity, keeping the humidity above the saturated humidity level. The moisture gradually permeates to the upper surface side, where the humidity is lower, through the moisture permeable membrane 19, which is most easily cooled by cold air hitting the upper surface. Therefore, it is possible to prevent a large amount of vegetables from being stored in the vegetable container 17, causing the humidity inside the vegetable container 17 to rise abnormally, causing dew condensation, and causing the water droplets to adhere to the vegetables and promote rotting of the vegetables.

Furthermore, by providing a curved shape in the seventh rank portion at the top of the vegetable container 17, the adhesion with the gasket is further improved. By cooling the vegetable container 17 from the entire circumference, it is possible to cool the vegetable container 17 with a smaller amount of cold air from the upper storage chamber 7 than in the past. There is no problem of over-cooling of the vegetable container 17, and dew condensation on the inner surface of the vegetable container 17 that still occurs due to extreme cooling is eliminated.

Effects of the Invention As described above, the present invention covers a gasket provided on the upper part of a vegetable container with a moisture-permeable membrane, and furthermore, allows cold air to flow between the partition plate that divides the refrigerator compartment into an upper and a lower storage chamber and the moisture-permeable membrane. Since the vegetable container is made to flow, the vegetable container can be cooled by efficiently passing cold air around and over the container, and the inside of the vegetable container can be maintained at a predetermined temperature with a small amount of air. Therefore, dew condensation on the inner surface of the vegetable container, which occurs due to extreme cooling, can be prevented, and the problem of excessive cooling of the lower storage chamber, which occurs due to a large amount of cold air, is also eliminated. Since the shredded vegetable container is covered with the moisture-permeable membrane, cold air does not directly enter the vegetable container, and the moisture evaporated from the vegetables stored inside the vegetable container keeps the inside of the vegetable container highly humid. It prevents vegetables in sauce from drying out, and maintains the freshness of vegetables for a long period of time by keeping the optimum humidity constant using a moisture-permeable membrane. Furthermore, since the upper opening of the vegetable container is covered with a single moisture-permeable membrane, it can be easily replaced if it gets soiled, and it is extremely convenient to use, which has some practical effects.
