* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 증발기 2 : 보조 증발기1: evaporator 2: auxiliary evaporator

3 : 감온관 4 : 열팽창밸브3: temperature reduction tube 4: thermal expansion valve

5 : 수액기 6 : 압축기5: receiver 6: compressor

본 발명은 냉장고의 수분제거장치, 특히 보조 증발기를 채용하여 냉장고의 수분을 물방울로 응결시켜 제거하는 냉장고의 수분제거장치에 관한 것이다.The present invention relates to a moisture removal device of the refrigerator, and more particularly, to a moisture removal device of the refrigerator which removes moisture by condensing the moisture of the refrigerator with water droplets.

통상, 냉장고의 냉동실과 냉장실을 경유하여 증발기로 귀환하는 냉기 내에는 다량의 수분의 함유되어 있다. 이같이 냉기 내에 함유되어 있는 수분은 증발기의 극저온에 의해 빙결되어 증발기의 표면에 다량의 성에를 형성하게 된다. 이같이 증발기의 표면상에 성에가 두텁게 형성되면 증발기 열교환성능이 감소하게 되므로 제상히터를 이용하여 성에를 제거해주어야 한다.Usually, a large amount of moisture is contained in the cold air returned to the evaporator via the freezer compartment and the refrigerating compartment of the refrigerator. The moisture contained in the cold air is frozen by the cryogenic temperature of the evaporator to form a large amount of frost on the surface of the evaporator. If the frost is formed on the surface of the evaporator in this way, the heat exchange performance of the evaporator is reduced, so the frost must be removed using a defrost heater.

따라서, 본 발명의 목적은 위와 같은 증발기로 귀환하는 냉기 내의 수분의 양을 감소시켜 줌에 의해 증발기에 생성되는 성에의 양을 감소시킬 수 있는 냉장고의 수분제거장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide a refrigerator moisture removal device that can reduce the amount of frost generated in the evaporator by reducing the amount of moisture in the cold air returned to the evaporator as described above.

위와 같은 목적을 달성하기 위해 본 발명에서는, 증발기, 압축기, 콘덴서, 수액기, 모세관이 냉매관으로 연결되어 냉동사이클을 구성하는 냉장고에 있어서, 상기 수액기와 압축기의 흡입측을 냉매관으로 연결하여 상기 냉매관로상에 설치된 보조증발기와, 상기 보조증발기와 수액기상이의 냉매관로 상에 설치된 열팽창밸브와 상기 보조증발기와 압축기의 흡입측 사이의 냉매관로 상에 설치된 감온관으로 구성된 냉장고의 수분제거장치를 제공한다.In order to achieve the above object, in the present invention, a refrigerator comprising an evaporator, a compressor, a condenser, a receiver, and a capillary tube connected to a refrigerant pipe to configure a refrigeration cycle, wherein the receiver side of the compressor and the suction side of the compressor are connected to the refrigerant pipe. A water evaporation device of the refrigerator comprising an auxiliary evaporator installed on a refrigerant passage, a thermal expansion valve installed on the refrigerant passage between the auxiliary evaporator and an infusion solution, and a temperature reduction tube installed on the refrigerant passage between the auxiliary evaporator and the suction side of the compressor. to provide.

이하, 첨부한 도면을 참고하여 본 발명의 일 실시예에 대하여 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

제1도는 본 발명의 일 실시예에 다른 냉장고의 수분제거장치의 회로를 보여주는 도식도이다.1 is a schematic view showing a circuit of a moisture removing device of a refrigerator according to one embodiment of the present invention.

도면에 도시되어 있는 바와 같이, 본 발명의 수분제거장치는 수액기(5)와 압축기(6) 사이에 설치한 보조증발기(2)를 포함한다. 이 보조증발기(2)의 하류측에는 온도감지센서가 설치되어 있고, 그 상류측에는 열팽창밸브(4)가 설치된다. 상기 온도감지센서로서는 감온관(3)을 사용하는 것이 바람직하다. 감온관(3)내에는 온도변화에 따라 팽창수축이 가능한 냉매가 주입되어 있다. 따라서, 상기 보조증발기(2)를 통과한 냉매의 온도가 소정치 이상으로 상승하면 감온관(3)내의 냉매가 팽창하여 연결관(3a)을 통해 이동하여 열팽창밸브(4)를 개방시킬 수 있다. 이같이 열팽창밸브(4)가 개방되면 수액기(5)로부터 보다 많은 양의 저온냉매가 보조증발기(2)로 공급됨으로써 상기 보조증발기(2)의 온도를 소정치로 유지할 수 있게 된다. 상기 열팽창밸브(4)는 약 -14℃의 온도에서 작동하도록 설정하는 것이 바람직하다.As shown in the figure, the water removal device of the present invention includes an auxiliary evaporator 2 provided between the receiver 5 and the compressor 6. On the downstream side of this auxiliary evaporator 2, a temperature sensor is provided, and on the upstream side, a thermal expansion valve 4 is provided. It is preferable to use the temperature sensor tube 3 as said temperature sensor. In the temperature reduction tube 3, a refrigerant that can expand and contract with temperature changes is injected. Therefore, when the temperature of the refrigerant passing through the auxiliary evaporator 2 rises above a predetermined value, the refrigerant in the temperature reduction tube 3 expands and moves through the connection tube 3a to open the thermal expansion valve 4. . When the thermal expansion valve 4 is opened in this way, a larger amount of low-temperature refrigerant is supplied from the receiver 5 to the auxiliary evaporator 2 so that the temperature of the auxiliary evaporator 2 can be maintained at a predetermined value. The thermal expansion valve (4) is preferably set to operate at a temperature of about -14 ℃.

상기 보조증발기(2)는 냉장실 및 냉동실을 경유한 냉기를 증발기(1)로 귀환시키는 냉기흡입통로(도시생략)내에 설치하는 것이 바람직하다. 이에 따라, 냉장실 및 냉동실을 경유한 냉기가 상기 냉기흡입통로 내를 경유하는 동안에 이 냉기흡입통로 내에 설치된, 약 -14℃의 저온으로 유지되는 보조증발기(2)에 충돌하면 냉기내의 수분이 물방울로 응결함으로써 제거될 수 있다. 이같이 수분의 응결에 의해 생성된 물방울은 증발기의 제상수를 배수하는 통상의 제상수 배수관을 이용하여 배출할 수 있다.The auxiliary evaporator (2) is preferably installed in a cold air suction passage (not shown) for returning cold air via the refrigerating chamber and the freezing chamber to the evaporator (1). Accordingly, when the cold air passing through the refrigerating chamber and the freezing chamber collides with the auxiliary evaporator 2 installed at the low temperature of about -14 ° C while the cold air passes through the cold air suction passage, the moisture in the cold air flows into the water droplets. Can be removed by condensation. Thus, the water droplets generated by the condensation of water can be discharged using a normal defrost water drain pipe for draining the defrost water of the evaporator.

이상의 설명과 같은 냉장고 수분제거장치에 의하면 냉장실 및 냉동실을 경유하는 냉기 내의 수분의 양을 감소시켜줌에 의해 증발기에 생성되는 성에의 양을 극감시킬 수 있고, 이에 따라 증발기의 냉각성분을 향상시킬 수 있는 효과가 있다.According to the refrigerator moisture removing device as described above, by reducing the amount of moisture in the cold air passing through the refrigerator compartment and the freezer compartment, the amount of frost generated in the evaporator can be reduced, thereby improving the cooling component of the evaporator. It works.

이상은 본 발명의 일 실시예에 대한 설명이며, 본 발명은 그 요지구성의 범위 내에서 다양한 변경이 가능하다.The above is a description of one embodiment of the present invention, and the present invention can be variously modified within the scope of the gist structure.
