Description

[Detailed description of the invention] This invention efficiently cools the interior of containers such as crispers, which are stacked in two layers at the bottom of a refrigerator, by smoothly convecting cold air around the containers and suppressing drying. It is something.

Still another object is to provide convection of air around the container without adding special supports or the like.

In addition, the upper container is placed on a glass shelf that covers the upper opening of the lower container, so that the smooth surface allows for smooth sliding operation of the container in the front and back direction, and the glass shelf is strengthened. This prevents the risk of the glass shelf breaking even if a large amount of stored items are stored in the glass container.

The present invention will be explained in detail below based on the drawings.

Reference numeral 1 denotes a well-known heat insulating box body consisting of an inner box 2, an outer box 3, and a heat insulating material 4, the front opening of which is closed by a door (indicated by a dashed line 5), and a cooler (not shown) inside the refrigerator compartment 5. It is cooled to a predetermined temperature with cold air from the

The bottom rear wall of the inner box 2 is formed in a step-like manner so as to house a compressor (indicated by a two-dot chain line 6) on the outside of the refrigerator. A first protrusion 8 is integrally protruded.

The first protrusion 8 is formed in a step-like shape and is provided with a stopper surface 8A located forward of the inner box back wall and a mounting surface 8B on which the rear end edge of a first glass shelf (described later) is placed.

First shelf ribs 9, 9 are provided on the left and right side walls of the inner box at the same height as the mounting surface 8B of the first protrusion 8, and presser ribs 10, 10 for pressing the upper surface on the first glass shelf side are the first shelf ribs. 9, 9 and grooves 11 and 11, which are slightly larger than the thickness of the first glass shelf, are formed in a protruding manner.

The first glass shelf 12 is formed by, for example, ordinary glass having a thickness of 5 mm, and decorative frames 13 and 14 made of synthetic resin made by extrusion molding are fitted to the front and rear edges of the glass.

The rear decorative frame 14 is provided with a rising piece 14A and a hanging piece 14B that protrude upward and downward.
4A is the rear shelf 1 of food to be placed on the first glass shelf 12;
In addition to the role of the collar, the hanging piece 14B also plays the role of guiding cold air downward.

The left and right side edges of the first glass shelf 12 are inserted into the grooves 11.11, and the glass shelf 12 is stopped when the rear edge comes into contact with the flange surface 8A of the first protrusion 8.

Therefore, the upper surface of the first shelf ribs 9, 9 and the mounting surface 8B of the first protrusion 8
The first glass shelf 12 is supported, and an air passage is formed on the side of the first protrusion 8, that is, behind the rear edge of the first glass wJ12.

Further, second shelf ribs 15, 15 are provided on the left and right side walls of the inner box at a position slightly lower than the stepped upper wall 7A,
Groove 17.1 slightly larger than the thickness of the glass shelf (described later)
7 are formed.

Note that a stepped portion 18 on which the rear end edge of the second glass shelf is placed is formed at the intersection ridgeline of the stepped vertical wall 7B and the stepped upper wall 7A at the same height as the second shelf ribs 15, 15. .

Reference numeral 19 designates a cold air circulation recess formed across the stepped upper wall 7A and the stepped vertical wall 7B, which secures an air flow path behind the stopper surface of the second shelf rib 15 (the vertical wall surface 18A of the stepped portion 18). ing.

The second glass shelf 20 is made of tempered glass with a thickness of 6 mm (manufactured by heat-treating ordinary glass that comes out of a furnace by hardening) and a decorative frame 21 fitted to the front and rear edges of the tempered glass. 22.

The left and right side edges of this second force glass shelf 20 are inserted into the grooves 17.17, and the rear end edges are stopped by contacting the stopper surfaces 18A, 18A of the second shelf ribs 15, 15, and the second shelf ribs 15, 15 are stopped.
5. The second glass shelf 20 is supported by the upper surface of 15 and the upper surface of the stepped portion 18.

Note that support ribs 23, 23 are formed on the bottom wall of the inner box 2 in the front-rear direction to project upward and support the bottom surface of the second container (described later).

A first container 24 and a second container 25 are housed in the space below the first glass tM12 and the second glass shelf 20, respectively.

For example, two ribs 24A are provided on the lower surface of the bottom wall of the first container 24 on the left and right sides, and the ribs 24A abut and are supported on the upper surface of the second glass shelf 20.

Note that the upper opening of the first container 24 is covered by the first glass shelf 12, and the back surface of the upper part of the front wall hits the front surface of the front decorative frame 13, thereby stopping further insertion of the first container 24 to the rear.

Therefore, a space is formed behind the hanging piece 14B of the rear decorative frame 14.

When the first container 24 is pulled forward by placing a hand on the handle 24B, the rib 24A slides on the two glass surfaces of the second glass shelf 20 and the upper surface of the front decorative frame 21 and is smoothly pulled out.

Note that the length of the rib 24A is long enough to rest on the glass, and does not reach the top surface of the front and rear decorative frames 21 and 22.

This is because if the ribs 24A are placed on the top surface of the decorative frame, the load of the food stored in the first container 24 will be concentrated and the top surface of the decorative frame will wear violently when pushing the front and rear drawers. This is because it becomes unsightly.

Although not shown, the first container 24 may be divided into two parts within the width of the refrigerator and placed on the second glass shelf 20.

The second container 25 has ribs 25A on the lower surface of the bottom wall, similar to the first container 24.
Two protruding ribs are formed on the left and right sides, and these ribs 25A, 2
5A faces the support ribs 23, 23 of the inner box 2, and the second container 25 is substantially supported by the support ribs 23, 23.

The opening of the second container 25 is covered by the second glass shelf, and the back surface of the upper part of the front wall hits the front surface of the front decorative frame 21, thereby stopping further insertion of the second container 25 to the rear.

Therefore, a space is formed between the rear wall of the second container 25 and the stepped vertical wall 7B, and the bottom wall is connected to the supporting ribs 23, 23.
Since it is lifted up, a space will be created here as well.

When the second container 25 is pulled forward by placing a hand on the handle 25B, the rib 25A slides on the upper surface of the support rib 23 and is smoothly pulled out.

Note that since the inner box 2 is generally manufactured by a vacuum forming method, the rear part of the support rib 23 is thin, and if there is a risk that the top surface of the support rib 23 will be worn and torn due to the sliding operation of the second container 25, the inner box 2 is made in a U-shape. It is preferable to cover the upper surface of the support rib 23 with a protective material of the form.

Next, looking at the cooling inside the first container 24 and the second container 25,
Low-temperature air from above the refrigerator compartment 5 flows as shown by the arrow, enters the rear space of the first container 24 from the side of the first projection 8, that is, from behind the rear edge of the first glass shelf 12, and then enters the rear space of the first container 24. 7A and the vertical wall 7B to reach the rear space of the second container 25, the cold air flows forward in the space below the bottom wall of the second container 25, and circulates through the first. Second container 24.25
The room is indirectly cooled by this circulating cold air.

Therefore, both the upper openings of the containers are the first one. Second glass shelf 12.2
Since it is in a substantially airtight state at zero, less moisture is removed from the indoor air, making it suitable for storing vegetables and fruits.

Since the present invention is constructed as described above, an air passage for low-temperature air circulation can be ensured by the first protrusion, air circulation recess, and support rib, and it is inexpensive because no special support is required. Compared to methods that cut out the glass to provide air passages, there is less damage from glass breakage.

By appropriately selecting the distance of the stopper surface of the first protrusion from the back wall surface of the inner box, the amount of inflowing air can be greatly changed and the temperature inside the container chamber can be designed to a desired temperature.

In addition, since the first container rests on the top of the glass of the second glass shelf, the smooth glass surface makes it easy to slide back and forth, and since the second glass shelf is made of tempered glass, the inside of the first container Even if a large amount of food is stored in
This makes it much more difficult to break than when using regular glass.

Furthermore, since the support ribs are formed to protrude from the inner box toward the bottom wall of the second container, the second container does not have to be specially made into a mold.
It is easy to change the air passage cross-sectional area by appropriately changing the height of the support ribs, and the refrigerator can easily obtain a desired cooling temperature.
