Problems solved by technology

For this reason, it is difficult to increase the size of the separator in the thickness direction
If the size of the partition in the thickness direction becomes small, it will not be able to obtain a sufficient thickness as a heat insulating wall, resulting in an increase in the amount of heat intrusion into the box

Embodiment approach 1

[0023] The refrigerator according to Embodiment 1 of the present invention will be described. figure 1 It is a perspective view which shows the schematic whole structure of the cool box 1 of this embodiment. figure 2 It is a plan view which shows the structure of the vicinity of the left door 21 and the right door 22 of the cooler box 1 of this embodiment. Include figure 1 and figure 2 In the accompanying drawings below, the relative dimensional relationship, shape, etc. of each constituent member may not correspond to reality. In addition, about the positional relationship and direction of each structural member in this specification, it demonstrates seeing the cold insulation box 1 installed in the usable state from the front in principle. In this embodiment, a refrigerator having a freezer compartment and a refrigerator compartment is described as an example of the cooler box 1 , but the cooler box 1 may be a refrigerator with only a refrigerator compartment or a fre...

Embodiment approach 2

[0044] Next, Embodiment 2 of the present invention will be described. Figure 7 It is an exploded perspective view showing the structure of the separator 140 of this embodiment. In addition, the same code|symbol is attached|subjected to the component which has the same function and action as the separator 40 of Embodiment 1 mentioned above, and the description is abbreviate|omitted.

[0045] Such as Figure 7 As shown, the separator 140 of this embodiment has one or both of the front side member 43 and the back side member 44 (only the front side member 43 in this example) in the longitudinal direction (in this example, approximately Central part) is divided into two structures. That is, the front side member 43 is divided into the upper member 43a and the lower member 43b. The upper member 43a and the lower member 43b each have the connection part 63a, 63b which can be connected with each other by fitting or the like.

[0046] In addition, in the present embodiment, the u...

Embodiment approach 3

[0058] Next, Embodiment 3 of the present invention will be described. Figure 8 It is an exploded perspective view showing the structure of the separator 240 of this embodiment. In addition, the same code|symbol is attached|subjected to the component which has the same function and action as the separator 40 of Embodiment 1 mentioned above, and the description is abbreviate|omitted.

[0059] Such as Figure 8 As shown, in the separator 240 of this embodiment, either one of the front side member 43 or the back side member 44 (in this example, the front side member 43) has a structure divided into the following parts: The intermediate member 43e; the upper end member 43c (an example of an end member) located at one end (upper end) in the longitudinal direction of the intermediate member 43e and having a fitting shape with the upper end side hinge member 51; and the length of the intermediate member 43e The other end (lower end) in the direction has a lower end member 43 d (an ...

Abstract

A cold storage is provided with: a heat-insulating box (10) which is open at the front; a left door (21) and a right door (22), which swing open from the center and which open and close the opening; a partition body (40) which is rotatably attached through a hinge member to a portion of the free end of the left door (21), the portion facing the inside of the cold storage, and which closes the gap (24) between the left door (21) and the right door (22); and condensation-preventing heater (42) which prevents condensation from forming on the partition body (40). The partition body (40) is provided with: a front face-side member (43) which is disposed on the gap (24) side and to which the condensation-preventing heater (42) is provided; a back face-side member (44) which is fitted to the front face-side member (43) so as to be capable of sliding in the longitudinal direction and which forms a cylindrical body in cooperation with the front face-side member (43); and a heat-insulating material (45) which is provided within the cylindrical body.

Description

technical field [0001] The present invention relates to a cold storage box with a side-by-side door. Background technique [0002] As a measure to prevent cold air from leaking from between the left and right doors, a cooler box having a side-by-side door has a rotary partition that blocks the space between the doors on the free end side of one door. When one door is opened, the partition is guided to rotate by a partition rotation guide provided in the refrigerator box, and is folded so as to avoid the rotation track of the other door. In addition, when one door is closed, the partition body is guided by the partition body rotation guide to rotate in the opposite direction, wraps around the back side of the other door, and closes the gap between the two doors. [0003] In addition to the function of preventing cold air from leaking from the inside of the box to the outside of the box, the partition also functions as a heat insulating wall for preventing the intrusion of he...
