Description

Door combination structure of refrigerator

The present invention relates to a door coupling structure of a refrigerator, and more particularly, to a door coupling structure of a refrigerator to enable easy detachment and / or coupling of freezing and refrigerating chamber doors for preventing leakage of cold air provided in a refrigerator refrigerator. will be.

In general, a refrigerator used for home use is divided into a freezer compartment for storing an ice making container and a frozen food at a set temperature, and a refrigerating compartment in which a refrigeration object is stored. The freezer compartment and the refrigerating compartment door are rotatably coupled to prevent external leakage of the dispersed and circulated cold air.

In the conventional door coupling structure for coupling the freezer compartment and the refrigerating chamber door, as shown in FIGS. 1 and 2, the freezer compartment 10a and the refrigerating compartment 10b are held in front of the refrigerator body 10 made of a heat insulating structure. The freezing and refrigerating chamber doors 12 and 14 are rotatably coupled so as to be sealed from each other, and the upper and lower sides of the freezing and refrigerating chamber doors 12 and 14 have a predetermined depth in the inward direction. (12a) 12b (14a) 14b are formed, respectively.

An upper bracket 16 having a hinge shaft 16a is fixed to the upper part of the main body 10 by a fixing screw 18 so that a portion thereof is fitted into the upper hinge hole 12a of the freezing chamber door 12. The intermediate partition of the middle having an intermediate hinge shaft (20a) to be fitted into the lower hinge hole (12b) and the upper hinge hole (14a) of the refrigerating chamber door (14), respectively, to support the freezing and refrigerating chamber doors (12) (14). The bracket 20 is fixed.

The lower bracket 22 is fixed to the lower part of the main body 10, and the hinge bracket 22a fitted into the lower hinge hole 14b of the refrigerating chamber door 14 protrudes integrally from the lower bracket 22.

In the door coupling structure of the conventional refrigerator configured as described above, the intermediate bracket 20 protruding from the intermediate hinge shaft 20a to the intermediate partition wall for partitioning the freezing and refrigerating chambers 10a and 10b is fixed with the fixing screw 18. Next, the hinge shaft of the upper bracket 16 as the upper hinge hole 12a formed by standing the freezing chamber door 12 vertically while inserting the lower hinge hole 12b of the freezing chamber door 12 into the intermediate hinge shaft 20a. 16a) to fix the upper bracket (16) with a set screw (18).

And, the refrigerating chamber door 14 is fitted with the intermediate hinge shaft (20a) to the upper hinge hole (14a) formed on the upper portion thereof and at the same time the hinge shaft (22a) of the lower bracket (22) into the lower hinge hole (14b). Tighten with a set screw 18 to complete the combination of the refrigerating chamber door 14.

Thereafter, the handle 24 attached to the front surface of the freezer compartment 12 or the refrigerator compartment door 14 is pulled to store or remove the frozen and refrigerated food in the freezer compartment 10a or the refrigerator compartment 10b. 12 and 14 are rotated around the hinge shafts 16a and 22a and the intermediate hinge shafts 20a of the upper and lower brackets 16 and 22, and the freezer compartment 10a and / or the refrigerating compartment 10b are rotated. Open.

However, since the freezing and refrigerating chamber doors are rotatably coupled to the upper, middle and lower hinge shafts of the brackets fixed to the refrigerator main bodies as described above, a separate tool is used when carrying a large model refrigerator or when the door of the consumer is small. By disassembling the intermediate bracket fixed by the fixing screw from the middle partition wall and separating the freezing and freezing chamber doors, there is a problem in that the separation and / or combination of the door is inconvenient, and thus the workmanship is increased.

The present invention is to solve the above problems, an object of the present invention is to improve the freezing and refrigerating chamber door and the hinge structure coupled to the refrigerator body, when transporting the refrigerator, especially when the door of the consumer is small in the middle partition of the body It is to provide a door coupling structure of the refrigerator that can be easily separated and / or assembled only the freezing and refrigerating chamber doors without disassembling the mounted hinge using a separate tool.

Hereinafter, a preferred embodiment of the door coupling structure of the refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are views showing the door coupling structure according to the present invention, the main body 40 of the refrigerator is partitioned into a freezer compartment and the refrigerating chamber (40a) 40b by the intermediate partition 42, the main body 40 Upper and lower portions of the upper and lower brackets 16 and 22, which project the hinge shafts 16a and 22a, respectively, are fixed by fixing screws 18, and the intermediate partition 42 has a locking groove 42a and A plurality of reinforcing support grooves 42b are formed to have a predetermined interval.

The door engaging means is mounted in the locking groove 42a and the reinforcing support groove 42b, and the freezing chamber 40a is provided in the hinge shafts 16a and 22a of the door coupling means and the upper and lower brackets 16 and 22. The refrigerating and refrigerating chamber doors 12 and 14, which have upper and lower hinge holes 12a, 12b, 14a, and 14b, respectively, are detachably coupled to seal the refrigerating compartment 40b from the atmosphere. On one side of the 40, that is, the surface perpendicular to the middle partition 42, the fixing means is fixed by the fixing screw 44 to fix the door coupling means.

The door joining means is opposite to each other on both sides of the hinge shaft 52 protruding up and down so that a part is fitted into the lower surface and the upper hinge hole 12b, 14a of the refrigerating and refrigerating chamber doors 12 and 14, respectively. At the same time bent and fitted into the locking groove (42a) and at the same time protruding in the same surface on the hooking jaw 54 and the hook 56 and the locking jaw (54) that the fixing means is caught to be inserted into the reinforcing support groove (52b) The support protrusion 58 is provided with a protruding hinge 50.

The fixing means includes a fixing plate 62 fixed to one surface of the main body 40, a handle 64 hinged thereto, and a hook 66 connected to the handle 64 to be hooked to the hook 56. It becomes the latch 60.

Referring to the operation of the door coupling structure of the refrigerator according to the present invention configured as described above in detail as follows.

The upper and lower brackets 16 and 22 having the hinge shafts 16a and 22a protruding from the upper and lower sides of the refrigerator main body 40 are fixed with the fixing screws 18, and then the latches 60 are formed on one surface of the main body 40. The hinge shaft of the hinge 50 with the lower hinge hole 12b and the upper hinge hole 14a of the freezing and refrigerating chamber doors 12 and 14 while the fixing plate 62 of the fixing plate 62 is fixed with the fixing screw 44. 52) Insert each end.

Thereafter, the upper and lower hinge holes 12a and 14b of the freezing and refrigerating chamber doors 12 and 14 are respectively inserted into the hinge shafts 16a and 22a of the upper and lower brackets 16 and 22, respectively.
