Hereinafter, an apparatus for preventing scattering of defrost water according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 2 to 5, the defrost water scattering prevention device 10 proposed by the present invention is mounted on the top of the evaporator coil C, so that the defrost water is dropped from the top to the evaporator coil C in a multistage dropping method. It is a jetting structure.

That is, a plurality of fans 14 are disposed in front of the evaporator coil C, and the plurality of fans 14 are rotated by the motor 16. Accordingly, as the fan C rotates, the air in the refrigerator blows in the direction of the evaporator coil C to perform heat exchange with the refrigerant flowing inside the evaporator coil C.

At this time, the surface temperature of the evaporator coil C is lowered, which may cause ice to freeze. As a result, the ice is removed by spraying defrost water by the defrost water scattering prevention device 10.

The defrost water scattering prevention device 10 includes an outer spray box 16 having a plurality of spray holes h4 formed on the bottom; An injection pipe 18 disposed on the inner upper side of the outer spray box 16 to primarily supply defrost water; At least one spray water guide (20) disposed under the spray pipe (18) to store defrost water and then fall by overflowing; A divider 22 disposed inside the spray water guide 20 to divide the space into a plurality of spaces to prevent the falling defrost water from being concentrated to one side; It includes an inner spray box 24 disposed under the spray water guide 20 to store the falling defrost water and then drop it through the lower spray hole h3.

In the defrost water scattering prevention device 10 having such a structure,

The outer spray box 16 has a hexahedral shape and an injection pipe 18 is connected to the inner side. In addition, the upper portion of the outer spray box 16 may be closed so as to be open and closed, so that scattering that may occur during the process of falling of defrost water from the inside may be prevented.

The injection pipe 18 may be connected to a defrost water storage tank (not shown) to supply defrost water to the inside of the outer spray box 16.

That is, the injection pipe 18 includes a main injection pipe 26 and a plurality of sub injection pipes 28 branched from the main injection pipe 26.

Accordingly, the defrost water supplied through the main injection pipe 26 is branched and supplied to the plurality of sub injection pipes 28. In addition, a plurality of first injection holes h1 are formed in the sub-injection pipe 28 so that the conveyed defrost part may be sprayed to the outside and dropped.

The spray water guide 20 first stores the dropped defrost water and drops it into the lower inner spray box 24 in an overflow method.

Since the spray water guide 20 is configured in plural, defrost water falls from the sub spray pipe 28 by being disposed under each of the plurality of sub spray pipes 28. The spray water guide 20 may be dropped downward by overflowing after stored defrost water dropped by a certain space formed therein.

The spray water guide 20 includes a pair of walls 30 facing each other at a predetermined interval; A base 32 that connects the lower portions of the pair of walls 30 to each other to form a floor; It includes a second injection hole (h2) formed in the pair of walls 30 or the base 32 to discharge defrost water.

In more detail, the pair of walls 30 has a length enough to be disposed inside the outer spray box 16. In addition, since the width of the pair of walls 30 is similar to the diameter of the sub injection pipe 28, the defrost water discharged through the first injection hole h1 of the sub injection pipe 28 easily falls. Can be.

In addition, the pair of walls 30 and the base 32 form a space of a certain volume inside, and the defrost water dropped from the first injection hole h1 fills this space, and a certain amount or more is stored. In this case, it falls downward by overflowing the pair of walls 30.

At the same time, the defrost water may directly fall downward through the second injection hole h2.

As a result, the defrost water dropped on the spray water guide 20 falls into the lower inner spray box 24 by an overflow method and a direct drop method through the second injection hole h2.

In addition, when a certain amount of defrost water is filled in the spray water guide 20, the bar may be concentrated to one side, and this may be prevented by the divider 22.

The divider 22 includes a plurality of partition walls disposed between the pair of walls 30 to divide the interior into a plurality of spaces.

The divider 22 divides the interior of the spray water guide 20 into a plurality of spaces along the length direction. Accordingly, the defrost water that has fallen from the top to the spray water guide 20 is not unilaterally flowed to one side and concentrated, but is stored uniformly by being sequentially stored in a space partitioned by a plurality of dividers 22.

In addition, a sound absorbing material such as a sponge may be provided inside the spray water guide 20 to reduce noise. At this time, the sound-absorbing material may be disposed on the floor or filled inside. Thus, noise due to falling defrost water can be prevented.

In addition, the inner spray box 24 stores defrost water falling through the second spray hole h2 of the spray water guide 20, and then flows it downward through the third spray hole h3 formed on the floor.

That is, the inner spray box 24 has a hexahedral shape with an open lower part, and a plurality of third injection holes h3 are formed in the upper part.

Accordingly, the defrost water dropped from the spray water guide 20 flows down to the inside of the inner spray box 24 through the third injection hole h3.

In addition, defrost water flowing into the inner spray box 24 is stored in the outer spray box 16.

The outer spray box 16 forms a space of a certain volume therein, so that the main and sub injection pipes 28, the spray water guide 20, the divider 22, and the inner spray box 24 are arranged. , Defrost water falling sequentially from the top is finally stored.

Further, the defrost water stored in the outer spray box 16 may drop downward through the fourth injection hole h4 to remove ice from the surface of the evaporator coil.

In this way, defrost water first falls through the main and sub spray pipes 26 and 28, and the dropped defrost water is stored first by the spray water guide 20, and overflows secondly from the spray water guide 20. It falls by the furnace, flows down to the inside of the inner spray box 24, is stored secondary, and then falls thirdly through the fourth injection hole h4 formed at the bottom of the outer spray box 16 to the surface of the evaporator coil. Comes in contact with.
