본 고안은 제습기의 제상장치에 관한 것으로, 특히 제습기를 통과하는 공기의 흐름을 바꿔주어 증발기 표면에 낀 성에를 용이하게 제거할 수 있도록 된 제습기의 제상장치에 관한 것이다.The present invention relates to a dehumidifier of the dehumidifier, and more particularly, to a dehumidifier of the dehumidifier that can easily remove the frost on the evaporator surface by changing the flow of air passing through the dehumidifier.
종래 냉동싸이클의 원리로 구성된 제습기는 저온운전시(18℃이하)증발기에 성에가 끼고 이 성에가 시간이 지날수록 두터운 얼음으로 되어 결국 제습효과가 감소되었었다.The dehumidifier composed of the principle of the conventional refrigeration cycle was frosted in the evaporator during low temperature operation (below 18 ℃) and the frost became thick ice as time passed, and the dehumidification effect was reduced.
이의 해결을 위해 종래에는 2가지 방식의 구조로 된 제상장치가 사용되었었는데, 즉 저온에서는 사용되지 못하도록 증발기 표면온도가 0℃이하가 되거나 주변온도가 18℃이하가 되면 성에 제거장치가 동작하여 제습기의 제습동작을 멈추게 하거나, 온도감지장치에 저온상태가 인지되면 일정시간동안 제상 타이머에 의해 응축기의 고온의 가스가 솔레노이드밸브를 통해 증발기로 분사되어 성에를 제거하고 성에 제거후 다음 성에가 생성될때까지 정상동작하며 이후에는 다시 상기 제상동작을 실행하는 제상장치들이 사용되고 있었다.In order to solve this problem, a defrosting device having a structure of two types has been used. That is, the defrosting device operates when the evaporator surface temperature is 0 ° C or below or the ambient temperature is 18 ° C or below so that it cannot be used at low temperatures. When the dehumidification operation is stopped or the low temperature state is detected by the temperature sensing device, the hot gas of the condenser is injected into the evaporator through the solenoid valve by the defrost timer for a certain period of time to remove the frost and remove the frost until the next frost is formed. Defrosting devices which normally operate and then perform the defrosting operation again have been used.
이러한 제상장치들 중 상기 제습기의 제습동작을 멈추게 하는 제상장치는 단순히 실내공기에 의해서 제상을 실행하기 때문에 장시간 동안 제습작용을 할수 없다는 문제점이 있었고, 응축기의 고온의 가스가 솔레노이드밸브를 통해 증발기로 분사되는 제상장치는 솔레노이드 밸브의 동작시 제상소음이 크고 솔레노이드 밸브에서 냉매가 누설됨으로써 제습기의 성능이 저하된다는 문제점이 있었다.Among these defrosting devices, the defrosting device which stops the dehumidifying operation of the dehumidifier has a problem in that it cannot dehumidify for a long time simply because defrosting is performed by indoor air, and hot gas of the condenser is injected into the evaporator through the solenoid valve. Defrosting device is a problem that the defrost noise during operation of the solenoid valve is large and the performance of the dehumidifier is deteriorated by the leakage of refrigerant from the solenoid valve.
따라서, 본고안은 상기와같은 문제점들을 해결하기 위하여 이루어진 것으로써, 본 고안의 목적은 제상이 빠르게 실행되고 제상소음이 적으며 제습기 성능을 양호하게 유지시킬 수 있는 제습기의 제상장치를 제공하는데 있다.Therefore, the present subject matter has been made to solve the above problems, an object of the present invention is to provide a dehumidifier of the dehumidifier that can perform defrosting quickly, low defrost noise and good dehumidifier performance.

이하, 이와같이 구성된 제습기의 제상장치의 동작을 제1도 내지 제4도를 참조하여 설명한다.Hereinafter, the operation of the defrosting device of the dehumidifier configured as described above will be described with reference to FIGS. 1 to 4.
제상장치의 동작을 설명하기 위한 초기조건으로서는 상기 제습수받이통(32)의 제습수(36)가 가득차있지 않고 , 실내습도가 설정습도보다 높으며, 증발기(82)의 표면온도는 설정온도보다 높다고 가정한다, 이와같은 초기조건에서는 상기 만수방지스위치(30)의 가동접점(30a이 고정접점(30b)에 접속되고 , 자동습도조절기(40)의 가동접점(40a)이 고정접점(40b)에 접속되며, 상기 온도감지센서(80)의 고정접점(80a)과 고정접점(80b)은 개방된 상태가 된다, 이때, 절환부(90)의 가동접점(90a)은 접속되어 있으므로, 전원코드(9)를 전원단자에 삽입시키고, 메인스위치(20)를 온시키면, 압축기(60)에서 발생된 과전류에 위해 기동릴레이(70)의 릴레이 작동자(70a)가 상측으로 부세되어 기동릴레이(70)의 고정접점(70b)과 고정접점(70c)이 접속되며, 그 결과 전류는 메인스위치(20)로부터 만수방지스위치(30)의 가동접점(30a) → 만수방지스위치 (30) 의 고정접점(30b) → 자동습도조절기(40)의 가동접점(40a) → 자동습도조절기(40)의 고정접점(40b) → 과부하릴레이(50)의 고정접점(50a)→ 과부하 릴레이(50)의 가동접점(50b)→ 압축기(60)의 제1압축코일(60a)→ 기동릴레이(70)의 고정접점(70c)→ 기동릴레이(70)의 고정접점(70b) → 전원코드(10)의-단자로 흐른다.As an initial condition for explaining the operation of the defrosting device, the dehumidifying water 36 of the dehumidifying container 32 is not full, the indoor humidity is higher than the set humidity, and the surface temperature of the evaporator 82 is higher than the set temperature. Assume, in such an initial condition, the movable contact 30a of the water level preventing switch 30 is connected to the fixed contact 30b, and the movable contact 40a of the automatic humidity controller 40 is connected to the fixed contact 40b. The fixed contact 80a and the fixed contact 80b of the temperature sensor 80 are in an open state. At this time, since the movable contact 90a of the switching unit 90 is connected, the power cord 9 ) Is inserted into the power supply terminal and the main switch 20 is turned on, the relay operator 70a of the starter relay 70 is biased upward for the overcurrent generated by the compressor 60 so that the starter 70 of the starter relay 70 is turned on. The fixed contact point 70b and the fixed contact point 70c are connected, and as a result, current flows from the main switch 20. Movable contact 30a of water level preventing switch 30 → Fixed contact 30b of water level preventing switch 30 → Movable contact point 40a of automatic humidity controller 40 → Fixed contact point 40b of automatic humidity controller 40 → fixed contact point 50a of overload relay 50 → movable contact 50b of overload relay 50 → first compression coil 60a of compressor 60 → fixed contact point 70c of starting relay 70. ¡Æ the fixed contact 70b of the start relay 70 flows into the negative terminal of the power cord 10.
압축기(60)이 기동이 끝나면 기동릴레이(70)에는 정상전류가 흘러 릴레이 작동차(70a)가 하측으로 떨어지며, 전류는 메인스위치(20)로부터 만수방지스위치의 가동접점(30a)→ 만수방지스위치(30)의 고정접점(30b)→ 자동습도조절기(40)의 가동접점(40a) → 자동습도조절기(40)의 고정접점(40b)→ 과부하릴레이(50)의 고정접점(50a)→ 과부하 릴레이(50)의 가동접점(50b)→ 압축기(60)의 제2압축코일(60b)→ 전원코드 (10)의-단자로 흘러 압축기(60)의 정상운전이 이루어진다.When the compressor 60 is started, a normal current flows into the start relay 70 so that the relay operating car 70a falls downward, and the current flows from the main switch 20 to the movable contact 30a of the full water prevention switch → full water prevention switch Fixed contact 30b of (30) → movable contact 40a of automatic humidity controller 40 → fixed contact 40b of automatic humidity controller 40 → fixed contact 50a of overload relay 50 → overload relay The movable contact 50b of the 50 → second compression coil 60b of the compressor 60 flows into the negative terminal of the power cord 10 and normal operation of the compressor 60 is performed.
이때에 메인스위치(20)로부터 만수방지 스위치(30)의 가동접점(30a)→ 만수방지스위치(30)의 고정접점(30b)→ 자동습도조절기(40)의 가동접점(40a)→ 자동습도조절기(40)의 고정접점(40b) → 절환부(90)의 가동접점(90a) → 절환부(90)의 고정접점(90b)→ 팬모터(100)의 제1구동코일(L1)→ 전원코드(10)의 → 단자로도 전류가 흘러 팬모터(100)를 시계방향으로 회전시켜서 응축기 팬(1020을 시계방향으로 회전시킴으로써 실내공기를 증발기(82)에서 응축기(104)방향으로 이동시킨다.At this time, from the main switch 20, the movable contact 30a of the anti-water switch 30 → the fixed contact 30b of the anti-water switch 30 → the movable contact 40a of the automatic humidity controller 40 → the automatic humidity controller. (40) fixed contact point (40b) → movable contact point (90a) of switching unit 90 → fixed contact point (90b) of switching unit (90) → first drive coil (L1) of fan motor (100) → power cord Current flows to the terminal of (10), too, and rotates the fan motor 100 clockwise to rotate the condenser fan 1020 clockwise to move the indoor air from the evaporator 82 to the condenser 104.
실내공기는 상기 증발기(82)를 통과하는 동안 증발기(82)내의 차가운 냉매에 의해 제습된다. 이와같이 제습이 샐행되는 도중 상기 증발기(82)표면이 과도하게 냉각되어 증발기(82)표면에 성에가 끼거나 얼음이 형성되면, 상기 온도감지센서(80)의 고정접점(80a)과 고정접점(80b)이 접속되어 절환부(90)의 릴레이코일(92)에 전류가 흘러 가동접점(90a)과 고정접점(90c)이 접속된다. 따라서, 팬모터(100)의 제2구동코일(l2)을 통해 전류가 흐름으로써 팬모터(100)가 반시계방향으로 회전하여서 응축기 팬 (102)이 반시계방향으로 회전하여 실내공기가 응축기(104)에서 증발기(82)방향으로 이동한다. 이때 응축기(104) 주위의 더운공기가 증발기(82) 표면의 성에와 얼음에 접하여 성에와 얼음을 녹이게 되어 제상이 빠르게 실행된다.Indoor air is dehumidified by cold refrigerant in the evaporator 82 while passing through the evaporator 82. When the surface of the evaporator 82 is excessively cooled and frost or ice is formed on the surface of the evaporator 82 while the dehumidification is performed, the fixed contact 80a and the fixed contact 80b of the temperature sensor 80 are formed. ) Is connected, and current flows through the relay coil 92 of the switching unit 90 so that the movable contact 90a and the fixed contact 90c are connected. Therefore, as the current flows through the second driving coil l2 of the fan motor 100, the fan motor 100 rotates counterclockwise, so that the condenser fan 102 rotates counterclockwise so that the indoor air is condenser ( In 104 direction evaporator 82; At this time, the hot air around the condenser 104 is in contact with the frost and ice on the surface of the evaporator 82 to melt the frost and ice defrosting is carried out quickly.
제상이 완료되면 증발기 표면에 설치된 온도감지센서(800의 고정접점(80a)과 고정접점(80b)은 다시 개방되며, 절환부(90)의 릴레이코일(92)에는 전류가 흐르지 않아 절환부(90)의 가동접점(90a)과 고정접전(90b)이 접속되어서 상술한 바와 같은 정상적인 제습동작이 실행된다,When the defrost is completed, the fixed contact 80a and the fixed contact 80b of the temperature sensor 800 installed on the surface of the evaporator are opened again, and no current flows through the relay coil 92 of the switch 90 so that the switch 90 The movable contact 90a and the stationary contact 90b of () are connected to perform normal dehumidification operation as described above.
이상 설명한 바와같이 본고안에 따른 제습기의 제습장치는 제습기의 제상시에 팬모터의 회전방향을 바꾸어서 응축기 주위의 더운공기가 증발기 표면으로 이동하여 성에와 얼음을 녹임으로써 제상이 빠르게 실행되고 제상소음이 적으며 제습기의 성능을 양호하게 유지시킬수 있는 매우 뛰어난 효과가 있다.As described above, the dehumidifier of the dehumidifier according to the present invention changes the rotation direction of the fan motor during dehumidification of the dehumidifier, so that hot air around the condenser moves to the evaporator surface and melts frost and ice so that defrosting is executed quickly and defrost noise is low.
