냉동실(1)의 외부에는 압축기(3),응축기(4)와 팽창변(5)및 송풍기(6)를 고정한 냉동기(2)를 설치하고 냉동실(1)의 내부에는 입구(701)와 출구(702)를 형성한 케이스(7)를 고정하고, 케이스(7)내에는 여러개의 냉기발산판(9)에 냉매관(10)을 지그재그로 배관한 증발기(8)와 송풍기(11)를 설치하고,Outside the freezer compartment 1, a compressor 3, a condenser 4, an expansion valve 5, and a refrigerator 2 fixed with a blower 6 are installed, and an inlet 701 and an outlet 702 inside the freezer compartment 1. ), The case 7 is formed, and the evaporator 8 and the blower 11 in which the refrigerant pipe 10 is zigzag-piped are installed in a plurality of cold air diverging plates 9 in the case 7,

케이스(7)의 하부에는 물받이판(12)을, 증발기(8)의 상부에는 여러개의 살포구멍(130)이 뚫린 살포박스(13)를 고정하고, 전기의 살포박스(13)에는 여러개의 분사구멍(140)을 뚫은 분사관(14)을 고정하여 물탱크(16)의 물을 펌프(15)에 의하여 제상수입구로 공급시킬 수 있도록 한 것에 있어서,The bottom of the case 7 is fixed to the drip tray 12, the top of the evaporator (8) is fixed to the spray box (13) with a plurality of spray holes 130, the electric spray box 13, a plurality of sprays In fixing the injection pipe 14 bored through the hole 140 so that the water in the water tank 16 can be supplied to the defrosting inlet by the pump 15,

살포박스(13)에는 갓(17)을 고정하고 분사관(14)의 분사구멍(140)은 상부로 향하게 고정하여 제상수를 갓(17)에 분사하여 감압시킬 수 있도록 한 것인데,The spatula 17 is fixed to the shade 17 and the injection hole 140 of the injection pipe 14 is fixed to the upper to spray defrost water on the shade 17 to reduce the pressure,

본 고안에 따른 다른 실시예로는 도4와 같이 살포박스(13)와 다공판을 없이 구성할 수도 있고, 도5와 같이 분사관(14)에 노즐(19)을 고정하여도 동일한 기능을 발휘시킬 수 있다.In another embodiment according to the present invention may be configured without the spray box 13 and the porous plate as shown in Figure 4, even if the nozzle 19 is fixed to the injection pipe 14 as shown in Figure 5 exhibits the same function You can.

미설명부호 142는 작동하지 않을 시 분사관(14)내의 물을Reference numeral 142 indicates that the water in the spray pipe 14 should not be operated.

빼기 위한 잔여수배출구멍이고To drain out the remaining water

18은 드레인파이프이다.18 is a drain pipe.

이와 같이 된 본 고안은 냉동기(2)를 가동시키면 압축기(3)에서 압축된 냉매는 송풍기(6)의 송풍에 의해 응축기(4)의 열은 방열되고, 송풍기(11)에 의하여 입구(701)및 출구(702)로 순환되는 냉동실(1)내의 공기는 증발기(8)의 차거운 냉매에 의하여 냉각되어 냉동실(1)내의 온도는 점차 저온으로되게 되고,According to the present invention, when the refrigerator 2 is operated, the refrigerant compressed by the compressor 3 is dissipated from the heat of the condenser 4 by the blowing of the blower 6, and the inlet 701 is blown by the blower 11. And the air in the freezer compartment 1 circulated to the outlet 702 is cooled by the cool refrigerant of the evaporator 8 so that the temperature in the freezer compartment 1 becomes gradually low temperature.

장시간 가동으로 증발기(8)에 고정된 여러개의 냉기발산판(9)의 사이에 서리나 얼음이 달라붙어 냉기발산판(9)의 사이로 공기순환이 원활하게 이루어지지 않을 때에는 냉동기(2)의 작동을 중지시키고 분사관(14)으로 제상수를 분사하여 서리나 얼음을 녹여 물받이판(12)의 드레인파이프(18)을 통하여 배수시킨 후 다시 냉동기 (2)를 가동하여 냉동실(1)의 온도를 저온으로 냉각시키게되는 것은 종래와 동일한 바,When the frost or ice is stuck between several cold air diverging plates 9 fixed to the evaporator 8 by long time operation, and the air circulation is not smoothly performed between the cold diverging plates 9, the operation of the refrigerator 2 is stopped. Stop and spray defrost water into the injection pipe 14 to dissolve frost or ice and drain it through the drain pipe 18 of the drip plate 12, and then operate the freezer 2 again to lower the temperature of the freezer compartment 1 to a lower temperature. Cooling is the same as before,

상기에 있어서 본 고안은 살포박스(13)에는 갓(17)을 고정하고 분사관(14)의 분사구멍(140)은 상부로 향하게 고정하여 제상수를 갓(17)의 내면에 분사하여 갓 (17)에 부딪쳐 높은 수압을 감압되게하여 아래로 떨어지게 하였으므로 고루 분포되어 뿌려지게 된다.In the above, the present invention is fixed to the spray box (13) to the cap (17) and the injection hole 140 of the injection pipe 14 is fixed to the upper to spray the defrost water on the inner surface of the shade (17) 17) to hit the high water pressure to fall down, so evenly distributed and sprinkled.

이에 따라 살수가 매우 고르게 이루어지게되어 증발기(8)의 제상(除霜)은 신속하게 이루어지게 된다.As a result, watering is made very evenly, and defrosting of the evaporator 8 is performed quickly.

이와 같은 본 고안은 살포박스(13)에는 갓(17)을 고정하고 분사관(14)의 분사구멍(140)은 상부로 향하게 고정하여 제상수를 갓(17)에 부딪혀 높은 수압을 감압되게하여 아래로 고루 분포되어 살수되게 하였으므로 제상효율을 대폭 향상시킬 수 있는 효과가 있다.The present invention is fixed to the spout 17 in the spray box 13 and fixed to the injection hole 140 of the injection pipe 14 to the upper to impinge the defrost water to the guard 17 to reduce the high water pressure Since it is distributed evenly down and spraying, there is an effect that can greatly improve the defrosting efficiency.
