Description

Evaporator cover structure of refrigerator

The present invention relates to an evaporator cover structure of a refrigerator, and more particularly, to an evaporator cover structure of a refrigerator in which the drain plate is integrally injected into the evaporator rear cover to facilitate fixing of the heater pipe.

In general, as shown in FIG. 1, a refrigerator compartment 11 and a freezer compartment 12 are respectively formed inside the main body 10, and the front side of the refrigerator compartment 11 and the freezer compartment 12 are food stored therein. The doors 13 and 14 are coupled to open and close to store and draw out the backs, and a plurality of shelves 15 for seating foods and the like are coupled to the refrigerating chamber 11.

In addition, an evaporator 17 is installed inside the main body 10 to evaporate the condensed refrigerant sent from the compressor 16 to form cold air, and the cold air cooled by the evaporator 17 is a cooling fan 18. And according to the operation of the damper 19 is properly supplied into the refrigerating chamber 11 and the freezing chamber 12 to achieve the freezing and refrigeration.

Conventionally, such an evaporator is mounted on a rear cover 21 located on the rear side of the inner damper 20, as shown in FIG. 2, and a front cover 22 is located on the front side thereof, and the evaporator 17 The heater pipe 23 drawn out below is positioned at the bottom of the drain plate 24 and fixed to the bracket 25 by rivets or the like, and a motor for driving the cooling fan 18 to the bracket 25. 26 is mounted.

In addition, the internal damper 20 and the front cover 22 are each formed with cold air outlets 20a and 22a for discharging cold air generated in the evaporator 17 into the air.

Therefore, the cold air heat-exchanged in the evaporator 17 by the operation of the cooling fan 18 that is rotated in accordance with the drive of the motor 26 is discharged into the chamber through the cold air discharge port 20a, 22a, the evaporator 17 The drain water generated at the periphery of the c) is dropped into the drain plate 24 and then evaporated by the heat transferred from the heater pipe 23 to allow the treatment of the drain water.

However, in such a conventional refrigerator, the drain plate is supported by the heater pipe drawn out from the evaporator, and the heater pipe is fixed by a rivet or the like by a separate bracket, so that the number of parts is difficult, assembly is difficult, and the manufacturing cost is increased. There were several problems inherent.

Therefore, the technical problem to be solved by the present invention, that is, the purpose of the present invention is to solve the above-described problems, the object of the present invention is to insert the drain plate directly into the inner cover to minimize the number of parts and assembly is The present invention provides an evaporator cover structure of a refrigerator that is easy and can further improve productivity and reduce manufacturing cost.

In order to achieve the above object, the present invention, an evaporator for heat-exchanging ambient air to form cold air, and a refrigerator comprising a back cover on which the evaporator is mounted, wherein the back cover stores drain water generated in the evaporator. Drain plate is integrally formed, and the bottom surface of the drain plate provides a evaporator cover structure of the refrigerator, characterized in that a plurality of hook rings for fixing the heater pipe drawn out from the evaporator protruded.

Hereinafter, preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view showing the evaporator cover structure of the refrigerator of the present invention, Figure 4 is a partially enlarged cross-sectional view showing the main part of the present invention.

In the figure, the front cover 31 is positioned inside the internal damper 30, and the rear cover 32 is positioned on the rear side thereof.

Cold air discharge ports 31a and 32a through which cold air is discharged are formed in the front and rear covers 31 and 32, and a motor 34 for operating the cooling fan 33 above the rear cover 32. Is mounted, the lower side is equipped with an evaporator 35 for heat exchange of the ambient air.

In addition, the drain plate 36 is integrally injection-molded on the lower side of the rear cover 32, and a plurality of hooking rings 32a for inserting and fixing the heater pipe 37 drawn out of the evaporator 35 on the bottom surface thereof. ) Is formed.

The drain plate 36 is preferably formed of a metal material such as steel or aluminum.

The evaporator cover structure of the refrigerator according to the present invention configured as described above is a cold air discharge port (31a) (32a) by the operation of the cooling fan 33, the cold air heat exchanged in the evaporator 35 is rotated in accordance with the operation of the motor 34. Refrigeration and freezing is made by discharging into the refrigerator through.

At this time, the drain water generated in the evaporator 35 falls to the drain plate 36, and the drain water stored in the drain plate 36 is heated and evaporated by the heat transferred from the heater pipe 37 to drain water. Will be processed.

In addition, the heater pipe 37 is inserted into and fixed to the plurality of hooking rings 32a formed on the lower side of the front cover 31, thereby maintaining a firmly coupled state and facilitating the coupling of the heater pipe 37.

As described above, according to the present invention, the drain plate is integrally insert-molded under the front cover, and at the same time, as the hook ring for fixing the heater pipe is formed, the number of parts is reduced, the assembly is easy, the productivity is improved, and the manufacturing cost is improved. There are several effects, such as significantly reduced.
