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 with a fixing screw from the intermediate partition wall and then separating the freezing and freezing chamber doors, there is a problem that the separation and / or assembly 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 door without disassembling the fixed hinge, which can significantly shorten the labor accordingly.

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.

Hinges fixed to the intermediate partition wall by fixing the upper and lower brackets 16 and 20 with the hinge shafts 16a and 22a protruding from the upper, lower and middle partition walls of the refrigerator body 10 with the fixing screws 18. When the hinge pin 50 is penetrated by the through hole 40a of the 40, a part of the through part 52 is inserted into the through hole 40a while the locking part 54 is caught on the upper surface of the through hole 40a.

After that, the intermediate partition wall is inserted into the lower hinge hole 44b so that a part of the locking portion 54 is fitted into the lower hinge hole 44b while the upper hinge hole 44a of the freezer compartment 44 is inserted into the hinge shaft 16a of the upper bracket 16. The hinge 40 is fixed to the fixing screw 42 to complete the coupling of the freezer door 44.

Then, the refrigerating chamber door 46 is coupled to the through shaft 52 inserted into the hinge shaft 20a and the through hole 40a of the lower bracket 20. That is, while pressing the contact plate 60 interposed in the upper hinge hole 46a to make a space for inserting a part of the penetrating portion 52 into the upper hinge hole 46a of the freezer door 46. When the lift preventing projection 64 is inserted into the ball 46c, a space is formed as one end of the lift prevention projection 64 contacts the upper surface of the contact plate 60.

At this time, the elastic member 62 interposed in the lower portion of the contact plate 60 maintains the compressed state, and the hinge pin (63) is inserted into the slot 56a of the leaf spring 56 by the recess 52a of the through part 52. 50) to prevent omission.

On the other hand, when removing the freezer and / or the refrigerating chamber door in accordance with the precautions when transporting the refrigerator, remove the leaf spring 56 fitted in the recess 52a, and then pull the rising prevention projection 64, preventing the rise Since the projection 64 is separated from the contact plate 60, the contact plate 60 is moved by the restoring force of the compressed elastic member 62, and at the same time, the hinge pin 50 is pushed upwards, so that the refrigerating chamber door ( 46) can be easily separated.

In addition, when the freezing chamber door 44 is removed by artificially pushing the penetrating portion 52 inserted into the penetrating hole 40a of the hinge 40, the penetrating portion 52 is completely removed from the hinge 40, so the freezing chamber door is (44) can be separated. And, the combination of the refrigerating and / or refrigerating chamber door is to insert the hinge pin 50 in the lower hinge hole (44a) of the freezing chamber door 44 in the reverse order of the above-described method and then through the through portion 52 of the hinge pin (50) After insertion into the through hole 40a, the leaf spring 56 is fitted into the recess 52a of the through part 52 to be coupled thereto. At this time, by pressing the contact plate 60 interposed in the upper hinge hole 46a of the refrigerating chamber door 46 and pushing the rising prevention protrusion 64 to control the restoring force of the elastic member 62, the contact plate ( Contact with the top of 60).

According to the door coupling structure of the refrigerator according to the present invention as described above, by improving the freezing and refrigerating chamber door and the hinge structure coupled to the refrigerator body, it is fixed to the middle partition of the main body when transporting the refrigerator, especially when the door of the consumer is small Only the freezing and refrigerating chamber doors can be simply removed and / or assembled without disassembling the hinges using a separate tool, thereby significantly reducing the labor required.
