A tray 26 for accommodating and placing various articles to be refrigerated therein is accommodated in the refrigerator compartment 14 through the opening 22 so as to be drawn out to the outside.
[0003]
That is, as shown in FIG. 5, a plurality of (for example, two) shelf support pillars 30 are vertically provided at predetermined intervals in the front-rear direction on the left and right inner walls 28, 28 that define the refrigerator compartment 14, A plurality of locking holes 30a are formed in the shelf support pillar 30 at predetermined intervals in the vertical direction. And it is comprised so that the tray board 32 may be attached to the locking holes 30a and 30a in the same plane. As shown in FIG. 5, the tray plate 32 is formed in an L shape including a vertical side 32 a and a horizontal side 32 b by bending a plate material such as a sheet metal at a substantially right angle. Locking pieces 34, 34 are formed at the upper end edge of the vertical side 32a by being spaced apart by the interval between the locking holes 30a, 30a formed in the shelf support columns 30, 30. By engaging with the stop holes 30a, the tray plate 32 is attached to the shelf support columns 30 and 30 with the horizontal side 32b extending horizontally to the shelf support columns 30 (see FIG. 4).

[0004]
[Problems to be solved by the invention]
In the above-described vertical refrigerator 10, the shelf support columns 30, 30 for mounting the tray plates 32, 32 protrude inward from the left and right inner walls 28 by a length H (see FIG. 4). There is a problem that the internal volume that can be effectively used becomes small. That is, as the tray 26, it is necessary to use a tray having a width dimension that takes into account the protruding length (2 × H) of the shelf support columns 30, 30, which reduces the amount of articles to be refrigerated. In particular, when the refrigerator compartment 14 is vertically long like the vertical refrigerator 10 shown in the figure, the loss of the effective internal volume becomes large. In addition, by setting the thickness of the heat insulating material in the heat insulating box 12 thin, a required effective internal volume can be ensured without increasing the size of the refrigerator itself. It is pointed out that this causes another problem of dew condensation on the outer surface.
[0005]
Therefore, as a means for coping with the above problem, by directly attaching the tray plate 32 to the inner wall 28 of the refrigerator compartment 14, it is possible to reduce the loss of the effective internal volume without reducing the heat insulation effect. However, in this case, since the vertical side 32a of the tray plate 32 is substantially in close contact with the inner wall 28, the flow of cool air in the room is blocked by the horizontal side 32b of each tray plate 32, and the distribution of the indoor temperature becomes uneven. This causes a problem that the article to be refrigerated deteriorates. In addition, water drops flowing down the inner wall 28 accumulate on the horizontal side 32b of the tray plate 32, and the water drops may drop from the open end of the horizontal side 32b to the lower tray 26, and the problem of wetting the article to be refrigerated is pointed out. The

DETAILED DESCRIPTION OF THE INVENTION
Next, a tray support structure for a refrigerator according to the present invention will be described in detail below with reference to the accompanying drawings by giving a preferred embodiment. Note that the same members as those described in the related art are denoted by the same reference numerals.
[0009]
As shown in FIG. 1, a plurality of (two in the embodiment) locking holes 36 are formed in the inner wall 28 of the heat insulating box 12 in the vertical refrigerator 10 at a required interval in the front-rear direction. A plurality are also formed at required intervals in the vertical direction. The tray plate 32 is directly attached to the inner wall 28 through the locking holes 36 and 36 located in the same horizontal plane. The tray plate 32 is configured in an L shape in which a sheet metal is bent at a substantially right angle to form a vertical side 32a and a horizontal side 32b. As shown in the figure, the vertical side 32a is set to a length dimension (dimension in the front-rear direction) that is substantially the same as the separation dimension of the locking holes 36, 36 that are separated in the front-rear direction. In addition, a locking piece 34 that can be engaged with each locking hole 36 is formed. Then, by engaging each locking piece 34 with the corresponding locking hole 36, the tray plate 32 is attached to the inner wall 28.
[0010]
When the tray plate 32 is attached to the inner wall 28, as shown in FIG. 2, the vertical side 32a is substantially in close contact with the inner wall 28, and the horizontal side 32b connected to the lower end of the vertical side 32a is connected to the inner wall 28. It extends horizontally toward the inside. That is, the tray 26 for storing the article to be refrigerated is slidably mounted in the front-rear direction on the horizontal sides 32b, 32b of the tray plates 32, 32 which are attached to the left and right inner walls 28, 28 in the refrigerator compartment 14 so as to face each other. Is done. In addition, the code | symbol 42 in FIG. 1 shows the heat insulating material of the heat insulation box 12. FIG.
[0011]
As shown in FIG. 1, the horizontal side 32b of the tray plate 32 is formed with a through hole 38 that communicates with the vertical side 32a on the side where the vertical side 32a is connected, so that the cold air flowing along the inner wall 28 can be removed. It is configured to be able to circulate up and down via 38. The horizontal side 32b is set to have a longer dimension than the vertical side 32a, and a notch 40 is formed inwardly in a portion extending in the length direction from the end of the vertical side 32a. Yes. The notch 40 functions to define a required gap between the inner wall 28 and the horizontal side 32b in a state where the tray plate 32 is attached to the inner wall 28, and the cold air also flows through the notch 40. It is supposed to be. That is, even if the tray plate 32 is directly attached to the inner wall 28, the cool air flows up and down through the hole 38 and the notches 40 and 40, and the temperature distribution in the refrigerator compartment 14 can be made uniform. The tray 26 is set so as to be placed at a position where the hole 38 and the notches 40 and 40 in the horizontal side 32b are not blocked (see FIG. 2).
[0012]
As described above, in the tray support structure according to the embodiment, the tray plate 32 can be directly attached to the inner wall 28 without impairing the cool air circulation in the refrigerator compartment 14, so that the loss of the effective internal volume in the refrigerator compartment 14 is suppressed to a small extent. Further, it is possible to prevent deterioration of the article to be refrigerated due to uneven temperature distribution. Further, since the water droplets flowing down the inner wall 28 continue to flow down the inner wall 28 through the hole 36 and the cutout portions 40 and 40 even at the mounting position of the tray plate 32, the water droplets accumulate on the horizontal side 32b, It is possible to prevent water droplets from dropping downward from the open end of the side 32b to wet the article to be refrigerated.
[0013]
In the illustrated embodiment, the case where only one rectangular hole is formed on the horizontal side has been described. However, the present invention is not limited to this, and a plurality of rectangular or round holes are provided at predetermined intervals. You may make it form in. Further, the refrigerator in which the tray support structure is adopted is not limited to the vertical type, and may be a horizontal type.

【The invention's effect】
As described above, according to the tray support structure for a refrigerator according to the present invention, since the tray plate is directly attached to the inner wall of the refrigerator compartment, the loss of the effective internal volume in the refrigerator compartment can be reduced. In addition, since a hole is provided at a position that is not blocked by the slidably mounted tray on the horizontal side of the tray plate, the temperature distribution in the refrigerator compartment is made uniform without disturbing the cold air circulation in the refrigerator compartment. It is possible to prevent the article to be refrigerated from deteriorating depending on the storage position. Further, water drops flowing down the inner wall of the refrigerator compartment are not accumulated on the horizontal side, and there is an advantage that it is possible to prevent water drops from dripping from the open end of the horizontal side to wet the article to be refrigerated below.
