Embodiment approach 1

[0023] figure 1 It is a schematic front view of refrigerator 100 of Embodiment 1. The storage room of the refrigerator 100 for accommodating food and the like has a refrigerator compartment 102 installed on the uppermost floor, an ice making room 103 and a switching room 104 arranged side by side on the lower side of the cooling room 102, and a switching room provided in the ice making room 103 and a switching room. Freezer compartment 105 below compartment 104 and vegetable compartment 106 provided under freezer compartment 105 . The front opening of refrigerator compartment 102 is covered so as to be openable and closable by refrigerator compartment door 102a and refrigerator compartment door 102b, which are pivotally mounted with vertical hinges. The ice making room 103 has an ice making device that automatically makes ice from water in a water supply tank (not shown) installed in the refrigerating room 102, and the ice making room 103 can store ice made by the ice making...

Embodiment approach 2

[0073] In Embodiment 1 above, the back panel flange portions 8 a are formed on the upper and lower ends of the back panel 8 . And the protection member 10 is attached to the back panel 8 by fitting in the upper and lower two claw parts 10b of the protection member 10 respectively. Here, the fluidity of the foamed heat insulating material differs depending on its material, density, door shape, and the like. Therefore, in order to improve the fluidity of the heat insulating foam, the back panel 8 described in Embodiment 1 may be rotated by 90 degrees parallel to the inner panel 5 to fix the back panel 8 to the inner panel 5 . That is, the back panel flange part 8a is located in the right side end and the left side end of the back panel 8. As shown in FIG.

[0074] Moreover, the back panel 8 may form the back panel flange part 8a in both the upper side end, the lower side end, the right side end, and the left side end of the back panel 8. In order to improve the fluidity of the...

Abstract

An object of the present invention is to provide a refrigerator door and a refrigerator including the refrigerator door, which can suppress an increase in manufacturing cost and suppress a decrease in strength. The above-mentioned refrigerator door has: a door part containing a vacuum heat insulating material and filled with a foam heat insulating material; a frame attached to the door part to support the door part freely; The back panel on which the fixing member is attached, and the protection member attached to the back panel in such a way as to face the front end protruding toward the door side of the fixing member, fill the gap formed between the protection member and the back panel with hair. Foam insulation.

Description

technical field [0001] The present invention relates to a refrigerator door and a refrigerator provided with the refrigerator door. Background technique [0002] Conventionally, there has been proposed a refrigerator in which a control box for controlling various devices of the refrigerator is mounted outside the outer contour of the refrigerator made of polyurethane foam or the like (for example, refer to Patent Document 1). In the technology described in Patent Document 1, in order to fix the control box to the outer contour of the refrigerator, screws with a length of about 20 mm to 30 mm are fastened, for example. Furthermore, in order not to cause the tightened screws to penetrate into the vacuum insulation material provided in the outer contour of the refrigerator and cause damage to the vacuum insulation material, the part of the vacuum insulation material located at the screw fastening part is previously press-molded to make it The thickness is thinned, so that a pr...
