The present invention relates to a refrigerator, and more particularly, to a hinge structure for rotatably supporting a door.

In general, the refrigerator is configured to supply the cold air generated from the evaporator of the refrigeration cycle to the storage compartment to prolong the freshness of various foods for a long time.

As shown in FIG. 1, the refrigerator is a storage compartment 2 and 3 having an open front in a cabinet 1 constituting an outer body, and includes a freezer compartment 2 for storing frozen food and a refrigerator compartment for storing refrigerated food ( 3) is partitioned. And doors 4 and 5 provided with handles 4a and 5a to open and close the freezer compartment 2 and the refrigerating compartment 3 are hinged to the front face of the cabinet 1.

This hinge consists of an upper hinge portion 6, a middle hinge portion 7, and a lower hinge portion 8, which are fixed using bolts 7d. The upper hinge portion 6 and the middle hinge portion 7 provided on the upper side of the cabinet 1 are configured to support the freezing chamber door 4, and the lower hinge portion 8 provided on the lower hinge portion 8 and the lower portion of the cabinet 1 is a refrigerator compartment door ( 5) is configured to support. In particular, the middle hinge portion 7 provided in the front part of the cabinet 1 between the freezer compartment 2 and the refrigerating compartment 3 is composed of a middle hinge plate 7c provided by the hinge shafts 7a and 7b to protrude up and down. The heavy hinge plate 7c is fixed to the front surface of the cabinet 1 using the bolt 7d. In addition, shaft holes 4b and 5b are formed at upper and lower ends of the freezing chamber door 4 and the refrigerating chamber door 5 so that the hinge shafts 6a, 7a, 7b, and 8a are coupled to each other.

Therefore, the freezer door 4 is fitted with the hinge shaft 6a of the upper hinge 6 at the upper end and the upper hinge shaft 7a of the middle hinge 7 at the lower end thereof, so that the freezing chamber 2 is rotatable. ) Will be opened and closed. And the refrigerating chamber door 5 is inserted into the lower hinge shaft (7b) of the middle hinge (7), the lower end is fitted to the hinge shaft (8a) of the lower hinge (8), by rotating around the refrigerating chamber ( 3) will be opened and closed.

On the other hand, in recent years, each household also prefers a large-capacity refrigerator, and such a large refrigerator is too large to enter the room through the front door of the apartment. Accordingly, the cabinet 1 and the doors 4 and 5 are separated and transported separately, and then reassembled at the installation site. That is, the upper hinge 6 and the middle hinge 7 coupled to the bolt 7d are separated from the cabinet 1 using a spanner or the like, and then the doors 4 and 5 are lifted from the cabinet 1. . Then, the doors 4 and 5 and the cabinet 1 are transported indoors and assembled in reverse order at the installation site.

However, in the disassembly and assembly process of the doors 4 and 5, it takes time because the bolts 7d of the hinges 6, 7, and 8 have to be tightened and loosened, and in some cases, the doors 4 and 5 are frequently disassembled. If this occurs, the thread of the bolt (7d) is worn, making it difficult to reuse. In addition, since a spanner, that is, a separate tool is necessary to tighten and loosen the bolt 7d, it is impossible to disassemble and assemble the refrigerator door without the tool.

The present invention is to solve this problem, an object of the present invention is to attach and detach the hinge plate provided with a hinge shaft to support the door to rotate the movement to the cabinet using the coupling shaft and the coupling hole without using bolts. By combining it, it is to provide a refrigerator that facilitates disassembly and assembly of the cabinet and the door.

As shown in the refrigerator, the refrigerator according to the present invention is partitioned up and down by a partition wall so that the cabinet 10 and the storage compartment 20 and 30 in which the storage compartment 20 and 30 are formed so as to distinguish the freezer compartment 20 and the refrigerating compartment 30. ) Are provided with doors 40 and 50 for opening and closing. The door is divided into a freezer compartment door 40 that opens and closes the freezer compartment 20 and a refrigerator compartment door 50 that opens and closes the refrigerating compartment 30, which are hinged to the front surface of the cabinet 10 in a rotatable manner.

The hinge supports an upper end (not shown), a middle hinge part 60, and a lower end of the refrigerating chamber door 50 to support the upper end and the lower end of the freezing chamber door 40 in a rotatable manner on the front surface of the cabinet 10. It is divided into a lower hinge portion (not shown). The middle hinge part 60 is comprised of the hinge plate 61 which protrudes in the up-down direction, and the hinge board 61 couple | bonded with the intermediate part of the cabinet 10 in which the freezer compartment 20 and the refrigerating compartment 30 are distinguished. . The upper portion of the hinge shaft 62 is fitted into the shaft hole 41 formed at the lower end of the freezing chamber door 40, and the lower portion thereof is fitted into the shaft hole 51 formed at the upper end of the refrigerator compartment door 50.

And the hinge plate 61 of the middle hinge portion 60 is a characteristic element of the present invention using a coupling hole 64 formed in the cabinet 10 and the coupling shaft 63 provided to protrude in the hinge plate 61 and Peelability is possible, and its structure is as follows.

First, the hinge plate 61 is provided with a coupling shaft 63 on the rear surface in contact with the front surface of the cabinet 10 at regular intervals, the coupling shaft 63 is a rod-like small diameter portion 63a protruding rearward and its It is comprised by the large diameter part 63b with a relatively large diameter at the edge part. And the end of the hinge plate 61 is bent is formed a bending portion (61a) in contact with the side of the cabinet 10, which is fitted into the coupling hole (65a) to be described later when the hinge plate 61 is fixed The fastening shaft 65 is provided.

In the front portion of the cabinet 10 to which the hinge plate 61 is coupled, a large diameter portion 63b of the coupling shaft 63 is fitted to the coupling hole 64 to which the hinge plate 61 is coupled, and spaced apart from each other by a predetermined width. The keyway 64a is connected to the coupling hole 64 to the left side. In addition, the side portion of the cabinet 10 is provided with a secondary hinge plate 66 and the coupling rod 67 to prevent the hinge plate 61 is pushed to the right in the coupled state. The auxiliary hinge plate 66 is formed in a pair of fixing pieces 66a, each end of which is bent in a U-shape and spaced apart from each other, and the fixing pieces 66a are exposed to the outside of the cabinet 10. It is fixed. Each fixing piece (66a) is formed with a through hole (66b) to pass through the square rod-shaped coupling rod 67, the upper end of the coupling rod 67 is provided with a handle (67a) protruding to the outside The engagement rod 67 can be inserted or removed. Therefore, when the hinge plate 61 is fixed so that the bent portion 61a is positioned between the fixing pieces 66a and the coupling rod 67 is inserted into the through hole 66b, the hinge plate 61 is firmly fixed. This will be explained in detail once again. Reference numeral 65a is a fastening hole to which the fastening shaft 65 formed at the bent portion 61a is fitted.

Next, the assembly process of the heavy hinge portion 60 according to the present invention configured as described above will be described. First, when the hinge plate 61 is pushed to the left in a state where the large diameter portion 63b of the coupling shaft 63 is inserted into the coupling hole 64 formed in the front portion of the cabinet 10, the small diameter portion of the coupling shaft 63 ( The 63a) is fitted into the key groove 64a to prevent the vertical flow of the hinge plate 61. In addition, the bent portion 61a of the hinge plate 61 is positioned between the fixing pieces 66a to be in contact with the side surface of the cabinet 10, and the fastening shaft 65 provided therein is fitted with the fastening hole 65a. 61 is fixed more firmly. At this time, since the hinge plate 61 is pushed back to the right side, it is separated, so to prevent this, hold the handle 67a and insert the coupling rod 67 to penetrate the through hole 66b of the fixing piece 66a. . Therefore, the hinge plate 61 is prevented from being pushed to the right without applying an artificial force, thereby being firmly fixed to the front portion of the cabinet 10.

The hinge shaft 62 provided in the hinge plate 10 is coupled to the shaft holes 41 and 51 formed at the side ends of the freezing chamber door 40 and the refrigerating chamber door 50, thereby freezing chamber door 40 and the refrigerating chamber door 50. ) Is rotatably coupled to the front surface of the cabinet 10 to open and close the freezer compartment 20 and the refrigerating compartment 30.

On the other hand, the super-large refrigerator is too large to pass through the door of the apartment, such as when changing the installation location or transport, and the weight is quite heavy, so often the door (40, 50) is separated, the present invention is applied In the case of the refrigerator, disassembling the doors 40 and 50 can be performed very easily by assembling the middle hinge plate 61 in the reverse order.

That is, by holding the handle 67a and pulling out the coupling rod 67 from the fixing piece 66a, and slightly pulling the hinge plate 61 to the right side, the small diameter portion 63a is pulled out of the key groove 64a and the coupling hole 64. ) And the fastening shaft 65 is also separated from the fastening hole (65a). In this state, when the hinge plate 61 is pulled forward of the cabinet 10, the coupling shaft 63 is separated from the coupling hole 64. Subsequently, when the hinge shaft 62 is removed from the freezing chamber door 30 and the refrigerating chamber door 40 through the shaft holes 41 and 51, the freezing chamber door 40 and the refrigerating chamber door 50 are easily connected to the upper hinge portion (not shown). It is separated from the lower hinge part (not shown) and disassembled simultaneously with the cabinet 10. Then, the disassembled freezer door 40, the refrigerating chamber door 50, and the cabinet 10 are transported to the installation place, respectively, and then assembled again as described above.

Therefore, in order to disassemble and assemble the doors 40 and 50 for opening and closing the storage compartments 20 and 30, the hinge plate 61 of the heavy hinge part 60 is disassembled and assembled in the cabinet 10. This process is combined without a separate tool. Since only the rod 67 is used, the time can be shortened, and this can be facilitated.

As described in detail above, the refrigerator according to the present invention can attach and detach a hinge plate provided with a hinge shaft to support the door in a rotatable manner using a coupling hole formed in the cabinet and a coupling shaft provided in the hinge plate without using bolts. Combined together. Therefore, when changing and transporting the installation place, the carrier disassembles the hinge plate, disassembles the door from the cabinet, moves it separately, and reassembles it without a separate tool, thereby improving workability. In addition, in the production line of the refrigerator there is an advantage that the manufacturing cost is reduced by the easy assembly of the door.
