Description

The techniques disclosed herein relate to cooling storage.

Conventionally, the cooling storage has a cooling storage main body which is a heat insulating box body. Patent Document 1 has a structure in which the opening of the cooling cabinet body is partitioned to the left and right by a partition frame. The partition frame is composed of a metal front frame, a resin cover that is one size larger than the front frame and covers the inside of the front frame, and a heat insulating material that is filled inside. In addition, a metal stay is attached to the inner surface of the resin cover to attach a shelf board or the like.

Japanese Unexamined Patent Publication No. 2006-284064.

Since the partition frame (pillar) fixes the stay, the load of a heavy object placed on the shelf board is applied to the stay fixing portion of the partition frame. Therefore, there is a concern that the load is concentrated on the stay fixing portion of the partition frame and the stay fixing portion of the partition frame is damaged.

This specification is created in view of the above circumstances, and discloses a technique for suppressing damage to a prism by distributing the load applied to the prism to the main body of the cooling cabinet.

The cooling storage disclosed in the present specification is a cooling cabinet main body having an opening composed of four inner peripheral walls on the front surface, and a bottom surface which is located at the opening of the cooling cabinet main body and constitutes the inner peripheral wall of the opening. It is provided with a pillar body connecting the wall and the upper surface wall, a pair of doors for opening and closing the opening divided into two by the pillar body, and a stay for attaching a support member for supporting the object to be cooled. A mounting surface for mounting the stay is provided on the wall surface of the inner wall of the prism, and the mounting surface is located on the upper surface of the bottom wall of the opening and is mounted on the mounting surface. The lower end surface of the stay abuts on the bottom wall of the opening.

In this configuration, since the load of the heavy object placed on the shelf board can be distributed to the cooling cabinet main body, it is possible to alleviate the concentration of the load on the stay fixing portion of the column body. Therefore, damage to the prism can be suppressed.

As one embodiment of the cooling storage, the following configuration is preferable.
The wall portion inside the column body has a recess between a pair of side walls, the bottom surface of the recess is the mounting surface of the stay, and in the recess of the wall surface, the bottom wall of the opening. Is exposed, and it is preferable that the bottom wall of the exposed opening receives the lower end surface of the stay attached to the mounting surface. In this configuration, a stay installation space can be created by forming a recess in the wall surface inside the column. Further, since the bottom wall of the opening is exposed in the recess, the lower end surface of the stay attached to the bottom of the recess can be received by the bottom wall of the exposed opening.

The cooler body has a double box structure composed of a metal outer box and a metal inner box, and the inner peripheral wall of the opening of the cooler body is the edge of the outer box and the inner box. It is preferable that the gap is filled with a resin joiner for connection, and the joiner on the bottom wall of the opening receives the lower end surface of the stay attached to the mounting surface. In this configuration, the load of a heavy object placed on the shelf board can be distributed to the joiner. Therefore, it is possible to alleviate the concentration of the load on the stay fixing portion.

The prism includes a metal outer frame located on the outside of the refrigerator and a resin inner frame located on the inside of the refrigerator, and the mounting surface is provided on the wall surface inside the inner frame of the inner frame. Is preferable. Since the inner frame is made of resin, the stay fixing portion is particularly liable to be damaged when the load of a heavy object placed on the shelf board is concentrated. By applying this technology, it is possible to solve the problem peculiar to the inner frame that the stay fixing portion is easily damaged due to the concentration of load.

According to the present invention, damage to the prism can be suppressed.

Hereinafter, the configuration of the inner surface walls 61 to 65 of the opening 60 will be described by taking the bottom surface wall 61 as an example. As shown in FIG. 14, the bottom wall 11A of the outer box 11 is folded upward at the front end of the cooling cabinet main body 10 to provide a vertical wall 11F. On the other hand, the bottom wall 13A of the inner box 13 is gently curved upward near the front end of the cooling cabinet body 10, and the height is substantially the same as the upper end of the vertical wall 11F provided at the front end of the bottom wall 11A. There is. The first flange 12 and the second flange 14 are bent and formed at the upper ends of the vertical wall 11F of the outer box 11 and the bottom wall 13A of the inner box 13, respectively. The two flanges 12 and 14 are arranged so as to face each other so as to face each other in the front-rear direction (Z direction), and face each other horizontally. As described above, the first flange 12 and the second flange 14 are horizontally facing facing portions. Then, there is a gap between the tip of the first flange 12 (the edge on the outer box side) and the tip of the second flange 14 (the edge on the inner box side), and the gap is filled with the joiner 70 which is a connecting body. The two flanges (edges of the outer box and the inner box) 12 and 14 are connected to each other. The cooling cabinet main body 10 is also filled with a heat insulating material (omitted in FIGS. 13 and 14) between the outer box 11 and the inner box 13 on the front side corresponding to the opening 60.

The joiner 70 is made of synthetic resin and is formed by, for example, extrusion molding. The joiner 70 has a slightly thicker joiner body 71 that can be abutted over the outer surfaces of the two flanges 12 and 14. The joiner body 71 has a size that covers the two flanges 12 and 14. A support portion 72 is provided on the back surface of the joiner main body 71, and a pair of elastic pieces 75 and an engagement piece 76 are formed so as to extend back and forth at the protruding end of the support portion 72.

The pair of side walls 122, 122 are formed in the entire inner frame 122 in the vertical direction (Y direction). The recess 123 is located between the pair of side walls 122, 122. The recess 123 is recessed on the outer frame 110 side (lower side in FIG. 12), and the bottom surface thereof is the mounting surface 123A of the stay 150. Two stays 150 are mounted side by side in the width direction (X direction) on the mounting surface 123A. The stay 150 is made of metal and has a long shape in the vertical direction.

FIG. 13 is a vertical cross-sectional view of the pillar 100 and shows the mounting structure of the stay 150 with respect to the inner frame 120. The inner frame 120 is provided with stay fixing portions 127 at three locations, an upper portion, a central portion, and a lower portion.

The stay fixing portion 127 is a trapezoidal boss, and is formed so as to project inward from the back surface of the inner frame 120 to the inside of the pillar 100. The stay 150 is fixed to the inner frame 120 by fixing the stay 150 to the stay fixing portions 127 provided at the upper part, the central part, and the lower part with screws N1.

The stay 150 is a member for attaching a horizontal shelf board 180 (see FIG. 6) that supports the object to be cooled. The stay 150 is provided with a plurality of locking holes 160 for fixing the shelf plate 180 along the vertical direction. The stay 150 is also attached to the right side wall 10C and the rear side wall 10E of the cooling cabinet main body 10, and has a structure in which the shelf board 180 is supported by using the plurality of stays 150. The shelf board 180 is an example of a support member.

As described above, by providing the recess 123 in the wall portion 121 inside the inner frame 120, the joiner 70 is exposed in the recess 123 as shown in FIG. Then, as shown in FIG. 15, the lower end surface 151 of the stay 150 attached to the attachment surface 123A of the recess 123 is in contact with the exposed upper surface of the joiner 70, and the lower end surface 151 of the stay 150 is received by the joiner 70. There is. Specifically, it is received at a portion of the joiner 70 that overlaps the upper surface of the second flange 14 formed on the bottom wall 13A of the inner box 13. By receiving the lower end surface 151 of the stay 150 with the joiner 70, the load of a heavy object placed on the shelf board 180 can be transmitted to the refrigerator main body 10 via the stay 150 and dispersed. More specifically, the bottom wall 10A of the cooler main body 10 filled with a filler between the bottom wall 11A of the outer box 11 and the bottom wall 13A of the inner box 13 can be transmitted and dispersed.

Further, as shown in FIG. 15, a resin leg cover 170 is attached to the lower end of the pillar 100 by utilizing a pair of side walls 122 and 122 of the inner frame 120. The leg cover 170 improves the appearance by covering and concealing the connecting portion between the pillar 100 and the joiner 70.

(3) Effect of Embodiment Since the load of a heavy object placed on the shelf board 180 is applied to the stay fixing portion 127 of the inner frame 120, there is a concern that the stay fixing portion 127 may be damaged due to the concentration of the load. In particular, since the inner frame 120 is made of resin, it is easily damaged. In this configuration, by providing the recess 123 that serves as the placement space for the stay 150 on the wall portion 121 inside the inner frame 120, the joiner 70 is exposed in the recess 123, so that the jointer 70 is exposed under the stay 150. The end face 151 can be received by the exposed joiner 70. Therefore, the load of the heavy object placed on the shelf board 180 can be distributed to the joiner 70 and, by extension, to the bottom wall 10A of the cooling cabinet main body 10. Therefore, it is possible to alleviate the concentration of the load on the stay fixing portion 127 of the inner frame 120, and it is possible to prevent the stay fixing portion 127 of the inner frame 120 from being damaged.
