The present invention relates to a door hinge device for a refrigerator that facilitates disassembly and assembly to improve productivity and reduce manufacturing costs.

In general, the refrigerator includes a freezer compartment (7) and a refrigerating compartment (9) in which the upper door (3) and the lower door (5) are opened and closed in the main body (1) formed of a heat insulating material as shown in FIG. Compressors 11 for compressing the refrigerant are mounted on the lower side of the refrigerating chamber 9, and a condenser 13 for dissipating the high temperature and high pressure heat sent from the compressor 11 into the air is formed at the lower side of the refrigerating chamber 9, respectively. Buried

An evaporator 15 is provided between the freezing chamber 7 and the refrigerating chamber 9 to evaporate the refrigerant sent from the condenser 913 to perform a cooling operation. An evaporator is provided in the freezing chamber 7 and the refrigerating chamber 9. A blowing fan 19 is provided to rotate the cooling air formed around the periphery of the refrigerator 15 in accordance with the operation of the motor 17 to supply the freezing chamber 7 and the refrigerating chamber 9, and at the bottom of the refrigerating chamber 9. The evaporation plate 21 which collects the defrost water produced | generated in the kiln is inserted and installed.

In the above description, the first hinge bracket 23, the second hinge bracket 25, and the third hinge bracket 27 supporting the upper door 3 and the lower door 5 on one side of the front surface of the main body 1; The first, second, and third hinge brackets 23, 25, and 27 are provided with protrusions 23a, 25a, and 27a for engaging the upper door 3 and the lower door, and the protrusions 23a. (25a, 27a) is inserted into the through holes (3a, 3b, 5a, 5b) formed in the upper and lower cross-section of the upper door (3) and the upper and lower cross-section of the lower door (5) so that the upper and lower doors (3) and (5) are the main body ( It is combined with 1) to open and close.

Therefore, when the refrigerant gas compressed at a high temperature and high pressure in the compressor 11 is condensed while releasing heat from the condenser 13 to the outside, and then sent to the evaporator, the refrigerant in the evaporator 15 is evaporated while cooling the surrounding air to cool. The cooling air generated by the evaporator 15 is appropriately supplied to the freezer compartment 3 and the refrigerating compartment 5 by the operation of the blower fan 19 which is rotated according to the driving of the motor 17. Cooling is performed.

However, the door hinge device of the conventional refrigerator configured as described above has a problem in that the hinge brackets (first, second and third hinge brackets) must be removed when the door is disassembled, and in particular, the first hinge bracket when the lower door 5 is disassembled. After disassembling (23), removing the upper door (3), and disassembling the second hinge bracket (25), after separating the upper door (3), the problem of having to remove the lower door (5) There was this.

The present invention is devised to solve the conventional problems as described above, the purpose of the present invention is to allow the independent disassembly of the upper door and the lower door, and at the same time for a refrigerator that can simplify assembly and disassembly. It is to provide a door hinge device.

In the refrigerator door hinge device according to the present invention made to achieve the above object is a refrigerator having a plurality of hinge brackets for supporting the upper and lower doors, and the upper and lower doors coupled to the front and rear of the main body, The groove portion formed on one side of the upper and lower doors, the hinge shaft is inserted into the groove portion and the upper, lower and middle ends are supported by the hinge bracket, and the hinge shaft coupled to the groove portion It characterized in that it comprises a fixing pin inserted and fixed to one side of the groove portion to prevent.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 5.

In the drawing, reference numeral 1 denotes a main body, and a refrigerating chamber 7 and a freezing chamber 9 in which the upper door 3 and the lower door 5 are coupled to be opened and closed on the front of the main body 1, and the main body 1 A plurality of hinge brackets 31 coupled to the hinge shaft 29 supporting the upper door 3 and the lower door 5 are coupled to one side of the front by a fastening means (not shown).

As shown in FIGS. 3 and 4, a plurality of through holes 35 and 39 through which the fixing pin 33 is inserted are formed at one side of the upper door 3 and the lower door 5, respectively. On one side of the upper door (3) and the lower door (5) is formed a recess 37, one side of which is open to extrapolate the outer circumferential surface of the hinge shaft (29) to which the plurality of hinge brackets (31) are coupled.

Next will be described the operation and effect of the fixing device of the door for a refrigerator according to the present invention configured as described above.

First, a plurality of hinge brackets 31 to which the hinge shaft 29 is coupled are fixed to one side of the front surface of the main body 1 by fastening means (not shown), and formed on the upper door 3 and the lower door 5 side. The concave groove 37 is extrapolated to the outer circumferential surface of the hinge shaft 29, and the fixing pin 33 is provided in the plurality of through holes 35 and 39 formed in front of the upper door 3 and the lower door 5, respectively. The upper door 3 and the lower door 5 are fixed to the main body 1 so as to be able to be inserted through the main body 1.

In the refrigerator assembled as described above, when it is necessary to disassemble the door such as a service, first open the upper door 3, then pull out the fixing pin 33 inserted into the through-hole 39, The upper door 3 is simply separated from the hinge shaft 29.

The lower door 5 can also be easily separated in the same manner as above.

In the above description, the shape of the recess 37 formed on the side of the upper door 3 and the lower door 5 into which the hinge shaft 29 is inserted is not limited thereto, and is inserted as shown in FIG. It is also possible to have an Ω shape in which a locking step 37a is formed to prevent the hinge shaft 29 from being separated.

The Ω shaped groove portion 37 configured as described above has a separate fixing means, that is, a fixed hinge by forcibly pressing the hinge shaft 29 into the latching jaw 37a of the groove portion 37 when engaged with the hinge shaft 29. Since it can be combined easily without using (33), it is possible to improve assembly and disassembly, increase productivity, and reduce cost by reducing the number of parts.

As described above, the door hinge device for a refrigerator according to the present invention eliminates the inconvenience of having to disassemble the hinge bracket of each part during assembly and disassembly, and by removing only the fixing pin, the disassembly can be easily performed. It is a very practical design that improves productivity and workability by separating and reassembling doors and lower doors independently.

In addition, the door hinge device according to another embodiment of the present invention can not only facilitate the disassembly and assembly, but also reduce the number of parts, thereby achieving cost reduction and productivity improvement. It is a practical design.
