본 고안은 냉장고에 있어서 냉매순환구조의 개선에 관한 것으로써, 특히 냉장고의 초기 기동시 압축기로부터의 냉매가 증발기로 바로 급송되게 하여 냉장고 초기 기동시의 냉동능력을 향상시킬 수 있도록 안출한 냉장고의 냉매순환구조에 관한 것이다.The present invention relates to an improvement of a refrigerant circulation structure in a refrigerator, and in particular, a refrigerant of a refrigerator prepared to improve the freezing capacity at the initial startup of the refrigerator by allowing the refrigerant from the compressor to be immediately fed to the evaporator during the initial startup of the refrigerator. It relates to the circulation structure.
냉장고는 일반적으로 일정의 냉매를 압축기, 응축기, 팽창 모세관, 증발기등을 차례로 거쳐 다시 압축기로 돌아가는 과정을 반복순환시켜 필요한 냉각작용을 얻도록 하고 있다.In general, a refrigerator repeatedly cycles a predetermined refrigerant through a compressor, a condenser, an expansion capillary, an evaporator, and then returns to the compressor to obtain a required cooling action.
이러한 냉장고에 채용되는 냉매순환구조로서 종래의 냉매순환구조는 제2도에 도시한 바와 같이 냉장고(1')의 하부에 압축기(10')를 설치하고 이 압축기(10')로부터의 냉매가 먼저 냉장고 내부에서 발생한 이슬을 수집, 증발제거토록 하기 위한 증발명수 대상의 냉매관(21')을 거친 후 응축기의 냉매관(20')과 팽창 모세관(19')을 거쳐 증발기의 냉매관(30')으로 유입되고 이 증발기의 냉매관(30')을 통과하면서 증발하여 주위의 열을 빼앗아 냉기를 생성한 후 다시 압축기(10')쪽으로 돌아가도록 되어 있다.As a refrigerant circulation structure employed in such a refrigerator, a conventional refrigerant circulation structure is provided with a compressor 10 'at the bottom of the refrigerator 1', as shown in FIG. 2, and the refrigerant from the compressor 10 'first comes first. After passing through the refrigerant pipe 21 'for the evaporation water to collect and remove the dew generated in the refrigerator, the refrigerant pipe 30' of the evaporator passes through the refrigerant pipe 20 'and the expansion capillary 19' of the condenser. ) Is evaporated while passing through the refrigerant pipe (30 ') of the evaporator to take the heat of the surroundings to generate cold air and then to return to the compressor (10').
이러한 종래의 냉매순환구조는, 냉장고(1')의 초기 기동시 증발기를 이룬 냉매관(30')내의 냉매가 아직 부족하여 냉기를 제대로 생성할 수 없는 상태에서 압축기(10')로부의 냉매가 증발명수대 및 응축기쪽의 긴 냉매관(21')(20')을 거친 후에야 증발기의 냉매관(30')에 이르도록 되어있기 때문에 그 초기 기동시간 동안에는 현저히 저급한 냉동능력을 제공할 수 밖에 없는 문제점이 있었다.In the conventional refrigerant circulation structure, the refrigerant to the compressor 10 'cannot be properly generated because the refrigerant in the refrigerant pipe 30' forming the evaporator at the initial startup of the refrigerator 1 'is still insufficient. Only after passing through the long refrigerant pipes 21 'and 20' at the evaporation water fountain and the condenser, the refrigerant pipes 30 'of the evaporator have to reach a significantly lower freezing capacity during their initial start-up time. There was this.
본 고안은 이와 같은 문제점을 해결하기 위해 안출한 것으로, 압축기에서 증발명수대 쪽으로 통하는 냉매관로 적소와 증발기 입구쪽의 냉매관로 적소사이에 전자변에 의해 개폐되는 보조냉매관을 연결설치하고 냉장고의 초기 기동시에는 압축기로 부터의 냉매가 상기 보조냉매관을 통해 증발기로 바로 신속 급송되게하여 냉장고의 초기 기동시부터 거의 정상수준의 양호한 냉동능력을 제공할 수 있도록 한 것이다.The present invention has been devised to solve such a problem, and installs an auxiliary refrigerant pipe opened and closed by an electronic valve between a refrigerant pipe path connected to the evaporation water fountain and an evaporator inlet in place. The refrigerant from the compressor is to be quickly fed to the evaporator through the auxiliary refrigerant pipe to provide a good freezing capacity of almost normal level from the initial startup of the refrigerator.
이러한 본 고안을 처부도면에 의거하여 더욱 상세히 설명하면 다음과 같다.When the present invention is described in more detail based on the drawing drawings as follows.
제1도는 본 고안에 따른 냉장고의 냉매순환구조를 도식적으로 나타낸 것으로, 이 냉장고(1)의 냉매순환구조는 냉장고의 초기 기동시를 지난 정상가동중에는 통상적인 냉장고에서와 같이 압축기(10)로 부터의 냉매가 증발 명수대쪽 냉매관(21)과 응축기의 냉매관(20)과 팽창 모세관(19)과 증발기의 냉매관(30)을 차례로 거쳐 흐른 후 압축기(10)로 다시 돌아가는 과정을 반복순환토록 되어 있다.1 is a view showing a refrigerant circulation structure of the refrigerator according to the present invention, the refrigerant circulation structure of the refrigerator (1) from the compressor 10 as in a normal refrigerator during normal operation after the initial startup of the refrigerator Of refrigerant flows through the evaporation water-side refrigerant tube 21, the refrigerant tube 20 of the condenser, the expansion capillary tube 19, and the refrigerant tube 30 of the evaporator, and then returns to the compressor 10 repeatedly. It is.
본 고안은 이러한 냉장고에 있어서, 상기 압축기(10)로부터 증발명수대쪽 냉매관(21)으로 통하여 냉매관로 적소와 증발기의 입구쪽 냉매관로 적소사이에 보조팽창 모세관(24)을 가진 비교적 짧은 길이의 보조냉매관(22)을 연결설치하고, 상기 보조냉매관(22) 및 증발명수대쪽 냉매관(21)으로 통하는 냉매관로의 연결부위에는 전자변(23)을 설치하여서 된 것이다.The present invention provides a refrigerator having a relatively short length having an auxiliary expansion capillary tube (24) between a refrigerant line in place and an inlet refrigerant line in place of the evaporator from the compressor (10) to the evaporation water side refrigerant line (21). The refrigerant pipes 22 are connected to each other, and the electron valve 23 is provided at the connection portion between the auxiliary refrigerant pipes 22 and the refrigerant pipes passing through the evaporation fresh water coolant pipe 21.
상기 전자변(23)은 마이콤과 같은 제어수단에 의해 냉장고(1)의 초기 기동시에는 압축기(10)로부터 증발명수대의 냉매관(21)쪽으로 통하는 냉매관로를 폐쇄함과 동시에 압축기(10)로부터 보조냉매관(22)쪽으로 통하여 냉매관로를 열어 압축기(10)로부터의 냉매가 상기 보조냉매관(22)을 거쳐 증발기의 냉매관(30)으로 바로 급송되게 하고, 이러한 초기기동시간이 경과하고 나면 앞서와는 반대로 보조냉매관(22)으로의 냉매관로를 폐쇄함과 동시에 증발명수대쪽 냉매관(21)으로의 냉매관로를 열어 압축기(10)로부터의 냉매관 증발명수대쪽 냉매관(21)과 응축기의 냉매관(20)등을 차례로 거친 후 증발기의 냉매관(30)으로 급송되는 정상적인 냉매순환 과정을 수행토록 하여 준다.The electromagnetic valve 23 is assisted by the compressor 10 while closing the refrigerant pipe from the compressor 10 toward the refrigerant pipe 21 of the evaporation water zone at the initial startup of the refrigerator 1 by a control means such as a microcomputer. Open the refrigerant passage through the refrigerant pipe 22 to allow the refrigerant from the compressor 10 to be fed directly to the refrigerant pipe 30 of the evaporator through the auxiliary refrigerant pipe 22, and after such initial starting time has elapsed On the contrary, the refrigerant path to the auxiliary refrigerant pipe 22 is closed and the refrigerant path to the evaporation water-side refrigerant pipe 21 is opened to open the refrigerant pipe from the compressor 10 to the evaporation water-side refrigerant pipe 21 and the condenser. After passing through the refrigerant pipe 20, etc. in turn to perform a normal refrigerant circulation process is fed to the refrigerant pipe 30 of the evaporator.
이와 같이 된 고안은 상술한 바와 같은 냉매순환구조에 의해 증발기의 냉매관(30)내의 냉매가 아직 부족한 냉장고 초기 기동시에는 전자변(23)이 압축기(10)로부터 증발명수대 및 응축기쪽 냉매관(21)(20)으로 통하여 정상적인 냉매순환 관로를 폐쇄함과 동시에 압축기(10)로부터 보조맹매관(22)으로 통하는 냉매관로를 열어주게 되어서 압축기(10)로부터의 냉매가 짧은 보조냉매관(22) 및 보조팽창 모세관(24)을 거쳐 증발기쪽 냉매관(30)으로 바로 급송됨으로써 냉장고 초기 가동시로부터 거의 정상수준의 양호한 냉동능력을 제공할 수 있고, 이러한 2~3분간의 초기기동시간이 지나고 나면 전자변(23)이 앞서와는 반대로 보조냉매관(22)쪽 냉매관로를 폐쇄하여 줌과 동시에 정상 냉매순환관로인 증발명수대 및 응축기쪽 냉매관(21)(20)으로 통하는 냉매관로를 열어주어서 정상적인 냉매순환을 이루게 된다.According to the above-described design, the electronic valve 23 is evaporated from the compressor 10 and the condenser-side refrigerant tube 21 at the time of initial startup of the refrigerator which is still short of the refrigerant in the refrigerant tube 30 of the evaporator due to the refrigerant circulation structure described above. The secondary refrigerant pipe (22) and the short refrigerant from the compressor (10) are opened by closing the normal refrigerant circulation pipe through the (20) and simultaneously opening the refrigerant pipe from the compressor (10) to the auxiliary blind pipe (22). Feeding directly through the auxiliary expansion capillary tube 24 to the evaporator-side refrigerant tube 30 can provide a good normal freezing capacity from the initial operation of the refrigerator, and after the initial starting time of 2 to 3 minutes In contrast to the foregoing, the refrigerant path to the secondary refrigerant pipe 22 is closed, and at the same time, the refrigerant path to the evaporation water zone and the condenser-side refrigerant pipes 21 and 20 is opened. Then normal circulation of refrigerant is achieved.
상기에서 보조냉매관(22)을 통한 냉장고 초기기동시의 냉매순환은 증발기쪽 냉매관(30)내에 냉매가 충분히 들어차기까지의 약 2~3분간의 짧은 시간동안에 이루어지는 한시적인 냉매순환이고, 이때 보조냉매관(22)에 작용하는(보조냉매관(22) 자체가 짧은 시간동안 어느정도의 응축기역할을 담당하게 됨)응축 방열부하는 그 다지 크지 않으므로 목적하는 바의 냉각작용수득상에 아무런 문제가 없다.In the above, the refrigerant circulation at the initial startup of the refrigerator through the auxiliary refrigerant pipe 22 is a temporary refrigerant circulation made in a short time of about 2 to 3 minutes until the refrigerant is sufficiently filled in the evaporator side refrigerant pipe 30. The condensation heat dissipation load acting on the subsidiary refrigerant pipe 22 (the subsidiary refrigerant pipe 22 itself serves as a part of the condenser for a short time) is not so large, so there is no problem in obtaining the desired cooling action. none.
이러한 본 고안은 상술한 바와 같은 특징적인 냉매순환구조 및 작용에 의해 냉장고의 초기 기동시로부터 거의 정상수준의 양호한 냉동능력을 제공할 수가 있기 때문에 전체적으로 더욱 향상된 냉동능력을 관련 냉장고에 제공할 수 있게 된 유용한 고안인 것이다.The present invention is able to provide a better freezing capacity as a whole as a function of the above-described characteristic refrigerant circulation structure and action from the initial start-up of the refrigerator can provide a more improved freezing capacity to the relevant refrigerator as a whole. It is a useful design.
