Description

냉동기의 증발기 냉기분사구조{EVAPORATOR COOL AIR HOOD STRUCTURE OF REFRIGERATOR}Evaporator cold air spray structure of the freezer {EVAPORATOR COOL AIR HOOD STRUCTURE OF REFRIGERATOR}

본 고안은 증발기에서 발생되는 냉기를 냉동실의 길이방향의 끝까지 보낼 수 있도록하여 냉동실에 저장한 저장품이 변질되는 것을 방지할 수 있도록 한 냉동기의 증발기 냉기분사구조에 관한 것이다.The present invention relates to an evaporator cold air spray structure of the freezer to be able to send the cold air generated in the evaporator to the end of the freezing chamber in the longitudinal direction to prevent the deterioration of the stored goods stored in the freezer.

종래의 5m-10m이내의 냉동실(1)의 내부에 사용되는 공기순환의 증발기중에서 팬을 사용하여 열교환작용을 하는 증발기의 단점은 팬의 날개에 의하여 분사되는 공기는 케이스(1)의 출구(702)로 배출시 상하좌우로 넓게 퍼져 사방으로 확산되려는 힘에 의하여 직진분사력이 떨어져 냉기는 도4와 같이 냉동실 끝까지 도달하지 못하게 되었다.The disadvantage of the evaporator which performs heat exchange using a fan among the air circulation evaporators used in the freezer compartment 1 within 5 m-10 m is that the air injected by the blades of the fan is the outlet 702 of the case 1. When it is discharged to), the direct ejection force is dropped due to the force spreading up, down, left and right and spreading in all directions, and thus the cold air cannot reach the end of the freezer as shown in FIG.

이에 따라 증발기(8)의 케이스(7)에서 분사되는 공기는 냉동실 끝까지 도달하지 못하고 증발기(8)가 설치된 케이스(7)의 입구(701)로 유입되어 다시 분사케됨으로 냉동실 각 부위의 온도분포가 고르지 못하게됨으로 인하여 저장품의 변질을 초래하게 되었다.Accordingly, the air injected from the case 7 of the evaporator 8 does not reach the end of the freezer compartment, but flows into the inlet 701 of the case 7 in which the evaporator 8 is installed. Unevenness has resulted in deterioration of the stored goods.

이의 문제점을 해소코져 도5와 같이 증발기케이스(7)의 출구(702)에 통풍닥트(15)를 설치하여 냉동실(1) 끝까지 골고루 냉기를 보낼 수 있도록 하고 있으나, 이는 길다란 통풍닥트(15)의 마찰저항에 의하여 분사되는 냉기분사력이 약해지기 때문에 큰용량의 모터에 의하여 팬(11)을 회전시켜야하게 됨으로 인하여 동력을 많이 소요하게됨과 아울러 길다란 통풍닥트(15)의 설치비의 부담이 따르게 되었다.In order to solve this problem, as shown in FIG. 5, the ventilation duct 15 is installed at the outlet 702 of the evaporator case 7 so that the cold air can be evenly distributed to the end of the freezing chamber 1, but the long ventilation duct 15 Since the cold jet force injected by the frictional resistance is weakened, the fan 11 needs to be rotated by a large capacity motor, which requires a lot of power, and the burden of the installation cost of the long ventilation duct 15 is accompanied.

본 고안은 상기와 같은 문제점을 해결하기 위하여 여러개의 냉기발산판(9)에 냉매관(10)을 지그재그로 배관하여서 된 증발기(8)를 고정한 케이스(7)의 출구 (702)에다 전면측으로 분사구(13')가 좁은 분사후드(13)를 고정하여 측면으로 넓게 퍼지는 냉기를 중앙으로 모아 좁은분사구(13')로 분사시키는 것에 의하여 분사력을 향상시킬 수 있도록 함으로서 도1과 같이 냉동실(1)의 끝까지 냉기를 보낼 수 있도록하여 저장물품이 변질되는 것을 방지할 수 있도록 한 것이다.In order to solve the above-mentioned problems, the present invention has a jet hole toward the front side of the outlet (702) of the case (7) in which the evaporator (8) fixed by zigzag pipes of the refrigerant pipes (10) to a plurality of cold air diverging plates (9).

도1 내지 도3에 도시된 바와 같이,As shown in Figures 1-3,

냉동실(1')의 외부에 압축기(3), 응축기(4), 팽창변(5)및 팬(6)을 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)이 지그재그로 배관된 증발기(8)와 팬(11)를 설치하고, 케이스(7)의 하부에는 물받이판(12)을 고정하여서 된 것에 있어서,A freezer 2 having a compressor 3, a condenser 4, an expansion valve 5, and a fan 6 fixed thereto is installed outside the freezer compartment 1 ′, and an inlet 701 and an outlet ( The case 7 having the 702 formed thereon is fixed therein, and in the case 7, the evaporator 8 and the fan 11 in which the refrigerant pipe 10 is zigzag-piped are installed in a plurality of cold air diverging plates 9, In the lower part of the case 7, the drip board 12 is fixed.

출구에는 전면측으로 분사구(13')가 좁은 분사후드(13)를 고정하여서 된 것인데, 분사후드(13)는 전면이 좁은 타원 및 사각등의 임의의 형으로 형성할 수 있고,At the outlet, the injection hole 13 'is fixed to a narrow injection hood 13 toward the front side. The injection hood 13 may be formed in any shape such as an ellipse and a square with a narrow front surface.

분사구(13')에는 냉기의 방향변화 및 냉기의 직전력향상등을 위하여 안내판 (14)을 설치할 수도 있다.The injection hole 13 'may be provided with a guide plate 14 for changing the direction of the cold air and improving the direct power of the cold air.

미설명부호 15는 통풍닥트이다.Reference numeral 15 is a gout duct.

이와 같이 된 본 고안은 냉동기(2)를 가동시키면 압축기(3)에서 압축된 냉매는 팬(6)의 송풍에 의해 응축기(4)의 열은 방열되고 팬(11)에 의하여 입구(701)및 출구(702)로 반복순환되는 냉동실(1)내의 공기는 증발기(8)의 차거운 냉매에 의하여 냉각되어 냉동실(1)내의 온도는 점차 저온으로되게 되는 것은 종래와 동일한 바,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 fan 6 and the inlet 701 and the fan 11 by the fan 11. The air in the freezer compartment 1 which is repeatedly 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, as is conventional.

상기에 있어서 본 고안은 내부에 증발기(8)를 설치한 케이스(7)의 출구(702)에는 전면측으로 점차 좁은분사구(13')를 형성한 분사후드(13)를 고정하였으므로 팬(11)에 의하여 발생되는 송풍은 분사후드(13)로 모아져 분사후드(13)의 전면의 좁은분사구(13')를 통하여 분사케됨으로 냉기의 직진분사력이 향상되기 때문에 분사되는 냉기는 도1과 같이 냉동실(1)의 끝까지 도달하여 케이스(1)의 입구(701)로 유입되어 다시 분사된다.In the above, the present invention is fixed to the outlet 11 of the casing 7 having the evaporator 8 installed therein, so that the injection hood 13 formed with a narrow injection hole 13 'is gradually fixed to the front side. The blowing air generated by the air is collected by the injection hood 13 and is injected through the narrow injection hole 13 'on the front surface of the injection hood 13, so that the cold air injected is improved because the direct injection force of the cold air is improved as shown in FIG. Reach to the end of the inlet is introduced into the inlet 701 of the case 1 and sprayed again.

이에 따라 냉동실(1)의 내부는 냉기의 순환이 골고루 매우 양호하게 순환케되어 저장물품이 변질되는 것을 방지할 수 있음과 아울러 종래에 마력이 높은 모터에 의하여 팬을 작동시키므로 인한 전력비의 부담과 길다란 통풍닥트(15)의 설치비의 부담을 덜 수 있다.Accordingly, the inside of the freezing chamber 1 can circulate the cold air evenly and prevent the deterioration of the stored goods, and also, because the fan is operated by a high-powered motor in the related art, the burden of power cost and long The burden of installation cost of the ventilation duct 15 can be reduced.

이와 같은 본 고안은 증발기(8)를 설치한 케이스(7)의 출구(702)에는 전면측으로 점차 좁은분사구(13')를 형성한 분사후드(13)를 고정하였으므로 팬(11)에 의하여 발생되는 송풍은 분사후드(13)로 모아져 좁은분사구(13')를 통하여 멀리까지 분사되기 때문에 냉동실(1)내의 냉기순환은 매우 양호하게 이루어지게되며, 이에 따라 냉동실(1)에 저장된 저장물의 변질방지효율을 향상시킬 수 있는 효과가 있다.The present invention as described above is fixed to the outlet hood 702 of the casing (7) in which the evaporator (8) is installed is formed by the fan (11) because the injection hood (13) gradually formed a narrow injection port 13 ' Since the blowing air is collected by the injection hood 13 and injected far through the narrow injection hole 13 ', the cold air circulation in the freezing chamber 1 is made very good, thus preventing the deterioration of the stock stored in the freezing chamber 1. There is an effect to improve.
