The present invention relates to a drain water discharge device of the refrigerator, and more particularly, it is possible to block the cold air exiting through the drain pipe when drain water is discharged, and also to prevent the refrigerator door from being opened due to the internal pressure of the refrigerator. It relates to a drain water discharge device.

In general, the refrigerator keeps the inside of the refrigerator at a low temperature by lowering the temperature in the refrigerator by the freezing cycle so as not to spoil the food stored therein. However, if the refrigeration cycle is continued, the evaporator through which the low-temperature low-pressure refrigerant passes will generate frost or condensed water due to the temperature difference with the external air on the outer surface of the refrigerant, thereby lowering the flow of the refrigerant, thereby lowering the cooling efficiency. The defrosting operation is performed to remove the defrosting every predetermined time to prevent the defrosting, and the defrosting removed by the defrosting device is discharged into the defrosting water. Or evaporate on their own.

However, when the drain water is discharged to the outside through the drain pipe, the cooling efficiency is lowered because the cold air in the refrigerator is discharged together. In order to prevent this, the drain trap 10 is used, and its configuration is illustrated in FIG. 1. As shown in FIG. 1, the drain trap 2 consists of a box-shaped trap body 10 having an open top and a cover 20 covering the open top of the trap body 10. Molded by The trap body 10 has an outer air hole 11 is formed on the upper wall surface thereof, the coupling groove 12 is further formed above the trap body 10. In addition, the two sides of the trap body 10 are formed with a slide groove 13 is formed long corresponding to each other up and down, the corner of the lower side of one side is formed in the form of a "??" shape, the "??" part The upper surface of the wall of the drain pipe (1) is connected to the coupling pipe path 14 is formed, and the upper and lower surfaces of the trap body 10 is further formed with a screw hole (16), respectively. In addition, the cover 20 forms a plate shape and a coupling hole 21 is formed at one side thereof to which the drain tube 1 is coupled, and a plate 22 is formed to protrude downward to be coupled to the slide groove 13. have. In addition, the coupling groove 12 is coupled to the blocking film 15 is formed with a protrusion to block the outer pores 11 formed in the lower portion is to be opened and closed inside the trap body (10).

In the above configuration, the cover body 20 is coupled to the trap body 10 to form a drain trap 2, and a passage having a shape in which substantially S-shapes are formed by the diaphragm 22 formed on the cover 20. As a result, the drain water becomes high, and when the drain water increases, the drain water overflows and is discharged to the outside through the lower drain pipe 1 connected to the coupling pipe line 14. In addition, when the internal pressure in the refrigerator is reduced, the outside air flows through the outside air 11 to increase the internal pressure, so that the refrigerator door is easily opened.

However, since the drain trap 2 formed by injection has difficulty in manufacturing the shape, the manufacturing cost is high, and the drain pipe 1 connected to the upper and lower portions of the drain trap 2 is formed coaxially. It is not convenient to install it, which is inconvenient to work. In addition, since the blocking film 15 is coupled in a form spanning the coupling groove 12 formed on the upper surface of the outer pores 14, a separate device is not provided so as to be in close contact with the outer pores 14. Due to the blocking effect is weak, there is a fear that the cold air in the interior leaks to the outside, if it is provided with a separate device for close contact with the configuration may be more complicated. In addition, in order to fix the drain trap 2 to the refrigerator, it is inconvenient to perform a separate operation in addition to fixing the drain pipe (1).
