Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a refrigerator having independent pull-out containers.

Prior Art FIG. 6 shows a conventional refrigerator. The conventional method will be explained below with reference to FIG. In the figure, reference numeral 1 denotes a refrigerator body, which is made up of an outer box 2, an inner box 3, and a heat insulating material 4 filled between the two boxes. This refrigerator body 1 is formed from top to bottom into a freezer compartment 5, a refrigerator 6, and a vegetable compartment 7, each with doors 8, 9, and 10.
is installed. The doors 8 and 9 of the freezer compartment 5 and the refrigerator compartment 6 are pivotally supported on one side and open laterally. Further, the door 10 can be freely pulled out by placing a frame 12 protruding from both ends of the back surface of the door 10 on a rail 11 provided on the side wall of the inner box 2 of the vegetable compartment 7 via rollers 12a and 12b. Reference numeral 13 denotes a partition wall that partitions the refrigerator compartment 6 and the vegetable compartment 7 through the front opening of the main body 1. Numerals 14 and 15 are containers with open tops having different depths, and are installed in the vegetable compartment 7. The lower container 14 on the deep side is placed on the frame 12 with its side portion and is taken in and out of the vegetable compartment 7 as the door 10 is put in and taken out. Also,
A shallow upper container 15 is located above the lower container 14,
A refrigerator 6 and a vegetable compartment 7 on an extension of the partition wall 13
It is placed on rails 13b provided at both ends of the lid body 13a located between them. When the door 10 is open (as indicated by the two-dot chain line in FIG. 6), the upper container 15 can be pulled out by holding the handle 16.

Problems to be Solved by the Invention However, in order for the lower container 14 to be usable for multiple purposes, it is designed so that it can store bottles.
In order to always form a deep space in the lower container 14 below the handle portion 16 of the upper container 15,
A gap 17 is formed between the containers 14 and 15 as shown in FIG. In addition, in order to ensure that the containers 14 and 15 can be operated independently, variations in the assembly of the rails 11 and 13b and deformations such as warpage and deflection of the lower container 14 and the upper container 15 are taken into consideration. The gap 17' between the upper container 15 and the lower container 14 also requires a relatively large gap as shown in Fig. 8, which has the disadvantage that the container is not tightly sealed and the drying of vegetables and other foods is accelerated, making it impossible to store the vegetables for a long time. It was hot. Note that a special sealing material is applied to the opening periphery of the lower container 14 and the upper container 15.
It is also known that the upper container 15 is interposed between the upper container 15 and the bottom surface of the upper container 15 to eliminate the gap 17, but if it is completely sealed, dew will form on the bottom surface of the upper container 15 due to the breathing action of the food such as vegetables, and this will cause the food to It has the disadvantage of dripping and spoiling food.

The present invention was devised in view of the above-mentioned drawbacks of the prior art, and its purpose is to prevent dew from forming inside the container due to the respiration of foods such as vegetables in the lower container, and to suppress drying as much as possible.

Means for Solving the Problems In view of the above problems, the present invention supports an upper container and a lower container by one rail, and makes the width of the bottom of the upper container larger than the width of the top opening of the lower container. be.

Function: Therefore, the gap between the upper container and the lower container can be made constant by the rail having an integrally formed flat surface that supports the upper container and the lower container.

Further, by arranging the upper container having a bottom surface larger than the upper opening of the lower container, movement of air from the upper container can be restricted.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. Structures that are the same as those of the prior art will be denoted by the same reference numerals and detailed explanation thereof will be omitted.

Reference numeral 21 denotes rails, which are provided on the side wall of the inner box 3 constituting the vegetable compartment 7 so as to be left and right opposite to each other in the depth direction. This rail 21 has an upper plane 21a and a lower plane 21b integrally formed vertically. Upper plane 2
1a includes a bottom surface 22a of an upper container 22 with an open top surface.
The corner portion 22b of is placed and serves as a sliding surface. Further, on the lower plane 21b is mounted a roller 24 attached to the rear of the frame 12 on which the peripheral edge end of the lower container 23 with an open upper surface is placed. Note that a roller 25 is attached to the rail 21, which contacts the lower surface of the frame 12 at a position slightly higher than the lower surface 21b of the rail 21.

The upper container 22 and the lower container 23 are
The upper container 22 is formed to have a higher height, and the front side of the upper container 22 has a tip that becomes a handle portion 22c, and the upper container 22 is designed so that tall items such as bottles can be stored in the lower container 23. handle part 2
2c is formed long in the depth direction.

Also, the upper container 22 is attached to the upper surface 21a of the rail 21.
The upper end 23a of the lower container 23 and the bottom surface 2 of the upper container when the lower container 23 is placed on the frame 12.
2a are close to each other, and the bottom surface 2 of the upper container 22
2a is selected to have a larger area than the upper opening of the lower container 23, and the gap 17 between the upper container 22 and the lower container 23 is kept almost constant. Also, the upper container 22
A protrusion 22d that protrudes from the gap 17 toward the lower container 23 is formed in the middle of the bottom surface.

This projection 22d is formed to be slightly longer than the gap 17 formed between the upper container 22 and the lower container 23, so that when the lower container 23 is pulled out, the rear end edge of the lower container 23 and the projection 22d are formed. When the lower container 23 is pulled out, the upper container 22 is also pulled out slightly.

In this way, since the upper plane 21a and the lower plane 21b of the rail 21 are integrally formed, variations in the vertical dimensions are reduced. In addition, since the corner portion 22b of the upper container 22 is placed on the upper plane 21a, even if the bottom surface is bent due to variations in the molding of the upper container 22 or when items are put therein, the container is the least likely to deform. Since the portion is placed on the upper plane 21a, the gap 17 between the opening edge of the lower container 23 and the opening edge of the lower container 23 is unlikely to change due to deformation. In addition, the bottom surface 2 of the upper container 22
Since the width of 2a is set larger than the width of the opening of the lower container 23, even if the left and right positions of the upper container 22 and the lower container 23 are shifted, the opening end of the lower container 23 and the bottom surface 22a of the upper container 22 will be aligned. The gap 17 formed can always be maintained constant.

Therefore, even if food such as vegetables in the lower container has a respiration effect, since the gap 17 is always maintained at a constant interval, dew will not form on the bottom of the upper container 22, and the vegetables etc. will not rot. There is no.

Effects of the Invention As is clear from the above embodiments, the present invention includes a rail in which an upper plane and a lower plane are integrally formed, a bottom corner part of an upper container supported by the upper plane, and a lower container supported by the lower plane. The upper and lower containers are supported by the same rail, and the gap between the two containers is maintained constant. Furthermore, by making the width of the bottom surface of the upper container larger than the width of the opening surface of the lower container, a gap between both containers is ensured even if the containers shift from side to side on the plane of the rail. Therefore, even if food such as vegetables breathes in the lower container, dew will not form on the bottom of the upper container and fall, causing the vegetables to rot.
