Abstract

PURPOSE:To prevent dry of vegetables, to prevent the occurrence of putrefaction due to formation of dew (waterdrops) occasioned by closing, and to enable division and arrangement to vegetables by a method wherein a large and a small container form structure in which the containers are approximately closed, and a passage through which cold air is forced to perform positive convection is formed between a partition plate for an upper and a lower storage chamber and a cover body. CONSTITUTION:Cold air from an upper storage chamber 9 is taken in through a first cold air intake port 49, but the length of a first cold air convention air passage 48 is shorter than that of a second cold air convection air passage 54 running along an outer periphery, and air passage resistance thereof is lower than that of the second cold air convection air passage. A convection amount of the first cold air convection air passage 48 is increased, moisture is gradually penetrated in the upper storage chamber 9, having low humidity, through a moisture penetrating film on the surface of a cover body 37. This constitution prevents formation of dew due to filling of the rear of a partition plate 6 with a moisture content. Meanwhile, a convection amount of the second cold air convection air passage 54 is decreased, and besides since containers 24 and 30 are covered with the cover body 37, the temperature of a rear part is not decreased so much, and a temperature difference between the inside and the outside of the containers 24 and 30 is suppressed.

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.

1 is the refrigerator main body, outer box 2, inner box 3, and both boxes 2, 3
It is constituted by a heat insulator 4 filled in between.

A heat insulating partition wall 6 with an open front side formed by the inner box 3
The upper freezing chamber 8, the upper storage chamber 9, and the lower storage chamber 1o are partitioned by a partitioning member consisting of a plate-shaped partition plate 6 and a heat insulating front 7, and each of these chambers 8, 9 .10 has its front opening closed by door bodies 11, 12 and 13 so as to be openable and closable.

The partition wall 6 has a compressor 14 disposed at the bottom of the refrigerator body and a condenser 16 disposed on the heat insulating material 4 side of the outer box 2.
A cold air passage 17 is formed in which a cooler 16 forming a refrigeration cycle is disposed, and the freezer compartment 8 is formed above and below the front insulation partition wall 6.
and suction ports 18 and 19 communicating with storage chambers 9 and 1o, respectively.
is formed.

20 supplies cold air cooled by the cooler 16 to the freezer compartment 8 and the storage compartments 9 and 1 through a duct 21 formed on the back surface of the inner box 2.
This is an air blower that blows air into the refrigerator from respective discharge ports 22 and 23.

24 is a large container with an open top for storing vegetables and the like in the lower storage chamber 1o, and is removably placed inside a support frame 26 provided on the door body 13 which can be freely pulled out.

The starting support frame 25 is equipped with rollers 26 protruding from the rear of the left and right sides and a stopper 27 provided on the bottom surface, and the rollers 26 are placed on a grooved support device 28 formed in the side wall of the inner box 3 in the front-rear direction. Meanwhile, the lower surfaces of the left and right sides of the support frame 26 are placed on rollers 29 protruding from the front of the side wall of the inner box 3. With this configuration, the door body 13 can be freely pulled out forward and backward using the support frame 26, the grooved support device 28, and the rollers 26 and 29.

Reference numeral 30 denotes an independent small container for storing vegetables and the like;
(not shown) and is located inside the front surface of the refrigerator main body 1. Due to these configurations, the door body 1
3 and when moving the small container 30 back and forth with the stopper 27 of the support frame 26 in contact with the roller 29, or when taking it out of the refrigerator main body 1 from the supporting and guiding rails, the back of the large container 24 It was necessary to provide a gap (not shown) between the bottom 32 of the small container 3o and the gap 33 so as not to touch the upper edge 31 of the opening, and also to prevent the side surface from touching.

Problem to be Solved by the Invention However, according to this particular configuration, the cold air taken in through the cold air intake port 34 from the upper storage chamber 9 flows into the container 2.
4. When convection flows around the outer circumference of 30, large container 24 and small container 3
Since the water directly enters through the gap 33 in the large container 24, the moisture that evaporates from the vegetables, especially leafy vegetables, in the large container 24 is carried away, resulting in dehydration and dryness, resulting in the problem that freshness can only be ensured for a short period of time. Ta.

For this reason, a structure has been considered in particular for the large container 24 in which a lid (not shown) whose outer periphery is sealed with a gasket or the like is brought into contact with the opening of the large container 24 to seal it. In addition, it is inconvenient to remove the lid, and the inside of the container becomes highly humid due to the respiratory heat transpiration of vegetables, especially leafy vegetables, creating a temperature difference between the large container 24 and the surface of the lid, and the inner surface of the container facing the lid. A large amount of dew condenses on the inner surface of the large container 24, which is locally cooled. As a result, water droplets fell from the inner surface and the lid that came into contact with the vegetables, causing the parts that came into contact to rot, which was a quality defect, and it was not put into practical use. In view of the above problems, the present invention
This solves the conventional problems, and in addition to preventing vegetables from drying out and rotting due to condensation M (water droplets) in an airtight container, it also enables vegetables to be sorted and sorted. The object of the present invention is to provide a refrigerator equipped with an independent container.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a small container having a large number of through holes, and a container side surface made of hydrophilic fibers on the opening side of the small container, and an outer (top surface) a member made of a moisture-permeable membrane such as a hydrophobic resin thin film, and a lid body provided with a guide rail portion on the inside of the flange to allow the small container to move freely back and forth;
The lower ends of the seven lunges on the left and right sides and the rear side of this lid are in close contact with the top surface of the support frame on the door body side, so that the large container and small container are almost sealed, and the upper storage chamber and the lower storage chamber are connected. A passage is provided between the partition plate and the lid to actively circulate cold air.

Effects of the present invention With the above-described structure, the large container and the small container are sealed by the lid body, and the large container and the small container are kept in the same temperature range by the numerous through holes provided in the small container, and in particular, the large container is stored in the large container. The water vapor generated by evaporation or respiration from the vegetables is permeated through the through holes of the small container to the surface of the lid, which is the lower humidity side, cooled by cold air convection between the partition plate and the lid. By preventing dew condensation on the surface of the small container and moderately suppressing the drying of the vegetables in each container, by positioning the lower end of the small container above the lower end of the 7-lunge of the lid, the large container , each small container can be operated independently.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 6.

Components that are the same as those of the prior art are designated by the same reference numerals, and their explanation will be omitted, and only the different parts will be described.

In the figure, reference numeral 13 denotes a door body, and a gasket 35 with a built-in magnet disposed on the peripheral edge of the back surface of the door body 13 is closely attached to the front surface of the refrigerator main body 1 to seal the lower storage chamber. 26 is a support frame fixed to the back side of the door body 13 with screws, etc., and the left and right sides 2
5a, 2tsb and rear side 25c and roller 2 at the rear
6 and extends substantially horizontally.

The side wall of the inner box 3 is provided with a grooved support device 28 on which the roller 26 slides, and the lower side of the support frame 26 is placed on a roller 29 protruding from the front portion of the side wall of the inner box 3. I support it.

24 is a large container placed on the support frame.

30 is the inner surface 3 of the extended front opening of the large container 24;
6, is placed on the inner rail portion 38 of the lid 37, and is supported in a position where the upper opening of the large container 24 is closed, and has a large number of through holes 39.

Reference numeral 37 denotes a plane part 41 having a large number of through holes 40, flanges 42a, 42b, 42a on both sides and the back, a tray/l/38 on which the small container 30 is placed on the inner surfaces 43 of the flanges 42a, 42b on both sides, and the plane. A moisture-permeable membrane 44 welded (or embedded, or held via a separate member) on the container-facing surface of the portion 41
It is a lid body made up of.

Upper surfaces 45a and 45b on each side of the support frame 25.

The flanges 42a, 42b, 42a of the lid body 37 are placed on the 450 and held and fixed.

When the large container 24 is stored in a predetermined position in the lower storage compartment 1o of the refrigerator compartment, the lid body 37 is attached to both sides 25a of the support frame.
, 25b and the upper surface 45a of the back side 25c.

It is in close contact with the upper surfaces of 45b and 45a.

Next, when the lower storage chamber door body 13 is pulled out, that is, when the support frame 26 is moving, the lid body 37 is attached to the support frame 26.
The front surfaces of the flanges 42a and 42b touch the stopper 46 of the grooved support device 28, which is formed on the side wall of the inner box 3, so that the lid 37 does not move. Furthermore, when the lower storage chamber door body 13 and the large container 24 are removed from the refrigerator main body 1 as shown in FIG.
The flange portions 42a and 42b of the lid body 37 rest on the upper surface 47 of the grooved support device 28 and are held therein.

The first one between the lid body 37 and the partition plate 6 located above the lid body 37
The cold air convection air passage 48 is substantially hermetically sealed. 49
is the cold air intake. 7 is a heat insulating front added laterally, and 50 is a cold air return vent.

Because of the above configuration, the large container 24° and the small container 3
There is no direct intrusion of cold air into the through hole 3 of the small container 3o.
The containers 24 and 30 communicate with the large container 24 through the container 9, and since there is no temperature difference within each container, the lid 37 sealed on the top surface of the small container 30 allows the containers 24 and 30 to absorb transpiration from the vegetables 51. On the other hand, the small container 30 maintains high humidity uniformly due to moisture.
On the side.

A through hole 63 is formed in the back wall 62 to allow moisture to escape.
Even if the bottom part 32 were covered with vegetables or the like, there would be no problem.

Moisture above the saturated humidity inside each container is permeated.

In other words, the cold air from the upper storage chamber 9 is taken in through the first cold air intake 49, and the first cold air convection air passage 48 has a shorter passage than the second cold air convection air passage 64 flowing around the outer periphery.
The air flow resistance is small, so the convection amount in the first cold air convection air path 48 is large, and the cool air gradually flows into the upper storage chamber 9, which has low humidity, through the moisture permeable membrane 44 on the surface of the lid body 37, which is cooled the most. Breathable.

Moreover, for this reason, moisture will not accumulate on the back surface of the partition plate 6 and cause dew condensation.

On the other hand, the amount of convection in the second cold air convection air passage 64 decreases, and in addition, since the lid body 37 covers the containers 24 and 30, the back surface becomes
The temperature does not become very low, and the temperature difference between the inside and outside of the container 24°3o is suppressed.

Effects of the Invention As is clear from the above explanation, according to the present invention, each container that can be pulled out independently is substantially sealed with a lid body equipped with a moisture-permeable membrane, so there is no cold air entering the container. Since the small containers have many through holes, the moisture from the vegetables stored in the containers evaporates to keep the inside of each container at a high and uniform level of humidity, allowing the vegetables to maintain their freshness for a long period of time. I can do it.

In addition, because the first cold air convection air path is formed to cool the surface of the lid made of a moisture-permeable membrane, the surface of the moisture-permeable membrane has the lowest temperature and lowest humidity relative to the inside of the container, and the moisture that evaporates from the vegetables in the container is reduced. The excess moisture does not condense on the other surface, but is concentrated on the surface of the moisture permeable membrane.

Moreover, according to the wooden structure, the effect can be achieved without using a lid body provided with a moisture permeable membrane for each of the large and small containers.

In addition, the lid is brought into close contact with the upper surfaces of the left and right rear sides of the support frame of the large container to seal the entire container, which is simple in structure and significantly reduces costs.

Even when the door of the lower storage compartment is removed, the lid and small container are retained by the grooved support device installed on the inner box wall, making handling easy and providing an excellent refrigerator in practical terms. have.
