Problems solved by technology

Coupling members (for example, screws for connecting a plurality of frame sides or frame bars 10a, 10b, and 10c, etc.) and reinforcement members (for example, ribs) for ensuring durability are necessary respectively, both of which are usually Increased manufacturing cost of conventional door frames
In addition, the labor involved in joining the individual frame bars must be carried out
It may also take heavy effort and labor to prevent the urethane foam resin filled in each frame from leaking through the joint between the frame bars
These problems and difficulties can lead to lower production efficiency
In addition, since the respective frames 10a, 10b, and 10c are coupled to each other, gaps may be formed between the frame bars or the frames are easily bent, so that the durability of the door deteriorates.

Abstract

The present invention relates to a refrigerator door frame and a manufacturing method thereof. In one embodiment, the refrigerator door frame comprises: a first side portion forming a first side of the door frame; a second side portion forming a second side of the door frame; a third side portion, It forms a third side of the door frame integrally coupled to the first side and the second side; and a fourth side forms the first side of the door frame. four sides, the fourth side portion is integrally coupled to the first side portion and the second side portion. In the refrigerator door frame, the first side, the second side, the third side, and the fourth side are integrally formed with each other, and the first side, the second side, and the fourth side are formed integrally with each other. At least one rib is formed on at least one of the second side, the third side, and the fourth side. The present invention enables better production efficiency and durability.

Description

technical field [0001] The invention relates to a refrigerator door frame and a manufacturing method of the refrigerator door frame. Background technique [0002] A refrigerator is a device used to store food in a temperature-controlled environment (eg, to help cool food, keep food fresh, etc.). A refrigerator generally includes a storage compartment, and the storage compartment is used through a door that can be opened and closed. Conventional refrigerator doors typically include a frame assembly and panels. [0003] Figure 15 is a block diagram for explaining an exemplary conventional refrigerator door including a frame assembly 10, a front panel 11 provided at the front side of the frame assembly 10, and a rear panel 12 provided at the at the rear side of the frame assembly 10 . The frame assembly 10 includes: two side frames 10a, which respectively include home bar seating parts A; an upper frame 10b, which is coupled to the upper sides of the two side frames 10a; an...
