It's about the refrigerator.
에어커튼이라 함은 고속으로 분사되는 공기에 의하여 외기와의 접촉을 차단시켜주는 작용을 하는 공기의 고속분사체를 의미한다.Air curtain means a high-speed jet of air that acts to block the contact with the outside air by the air injected at a high speed.
한편, 종래의 가정용 냉장고의 경우 냉장고 도어의 개방시에 외부로 방출되는 냉기를 막아주는 어떠한 수단도 설비되어 있지 않다. 따라서, 냉장고내에 실내의 공기가 직접적으로 유입됨으로써 보관 중인 음식물에 악영향을 미칠 수 있다. 따라서, 냉장고의 도어 개방시에 동작하는 냉기에어커튼을 형성해주면 위와 같은 냉장고 내에 외기가 직접유입되는 문제점을 제거할 수 있을 것이다.On the other hand, the conventional home refrigerator is not equipped with any means for preventing the cold air discharged to the outside when the refrigerator door is opened. Therefore, the air inside the refrigerator directly enters the refrigerator, which may adversely affect the food being stored. Therefore, by forming a cold air curtain operating when the door of the refrigerator is opened will be able to eliminate the problem that the outside air is directly introduced into the refrigerator as described above.
본 발명은 위와 같은 배경하에 안출된 것으로서, 본 발명의 목적은 냉장고의 도어 개방시에 외기가 냉장고 내에 유입되는 것을 방지하기 위한 에어커튼을 형성할 수 있는 장치를 구비한 냉장고를 제공하는 것이다.The present invention has been made under the above-described background, an object of the present invention is to provide a refrigerator having a device that can form an air curtain for preventing outside air from entering the refrigerator when opening the door of the refrigerator.
위와 같은 목적을 달성하기 위해 본 발명에서는, 냉장고의 냉동실과 냉장실을 구분하는 중간간막이판의 내측에 형성된 냉기공급덕트; 상기 냉기공급덕트의 하류측 단부에 설치된 송풍팬; 상기 송풍팬의 하측에 횡방향으로 형성되고, 하향 개방된 냉기분사슬롯; 냉장고 저면판의 상기 하향 개방된 냉기분사 슬롯에 대응되는 위치에 횡방향으로 형성되고, 상향 개방된 냉기흡입구; 상기 냉기흡입구 내에 설치된 냉기흡입팬; 및 상기 저면판 내에 형성되고, 냉장고 기계실에 연통하는 냉기이송덕트를 포함하는 것을 특징으로 하는 에어커튼 형성장치를 구비한 냉장고를 제공한다.In order to achieve the above object, in the present invention, the cold air supply duct formed on the inside of the middle partition plate for separating the freezer compartment and the refrigerator compartment of the refrigerator; A blowing fan installed at a downstream end of the cold air supply duct; A cold air injection slot formed in a transverse direction at a lower side of the blowing fan and opened downward; A cold air suction port formed in a transverse direction at a position corresponding to the downwardly opened cold air injection slot of the refrigerator bottom plate and upwardly opened; A cold air suction fan installed in the cold air suction port; And a cold air transfer duct formed in the bottom plate and communicating with the refrigerator machine room.
이하, 첨부된 도면을 참고하여 본 발명의 일 실시예에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.
제1도는 본 발명의 일 실시예에 따른 에어커튼 형성장치를 구비한 냉장고의 측단면도, 제2도는 제1도의 냉장고의 정단면도이다.1 is a side cross-sectional view of a refrigerator having an air curtain forming apparatus according to an embodiment of the present invention, and FIG. 2 is a front sectional view of the refrigerator of FIG.
제1도에 도시되어 있는 바와 같은 본 발명의 일 실시예에 따르면 냉장고의 냉동실과 냉장실을 구분하는 중간간막이판(20)의 내측에 냉기공급덕트(11)가 형성되어 있다. 상기 냉기공급덕트(11)의 상부에는 냉동실의 냉기를 증발기(10)로 귀환시키기 위한 덕트(21)이 형성되어 있고, 냉기공급덕트(11)의 하부에는 냉장실의 냉기를 증발기(10)로 귀환시키기 위한 덕트(22)가 형성되어 있다. 또한, 상기 냉기공급덕트(11)에는 억류방지밸브(11a)가 설치되어 있다.According to an embodiment of the present invention as shown in FIG. 1, a cold air supply duct 11 is formed inside the middle partition plate 20 that separates the freezer compartment and the refrigerator compartment of the refrigerator. The upper portion of the cold air supply duct 11 is formed with a duct 21 for returning the cold air in the freezer compartment to the evaporator 10, the lower portion of the cold air supply duct 11 returns the cold air in the refrigerating chamber to the evaporator 10. The duct 22 for making it is formed. In addition, the cold air supply duct 11 is provided with an arrest valve 11a.
상기 냉기공급덕트(11)의 하류측 단부에는 송풍팬(12)이 설치되어 있으며, 이 송풍팬(12)의 하측에는 하향 개방된 냉기분사슬롯(13)이 횡방향으로 형성되어 있다.The blower fan 12 is installed in the downstream end part of the said cold air supply duct 11, and the cold air injection slot 13 opened downward is formed in the horizontal direction below the blower fan 12. As shown in FIG.
또한, 제1도에서 참조번호(30)으로 도시한 냉장고 저면판에는 상기 냉기분사슬롯(13)으로 부터 분사되는 냉기를 흡입하기 위한 흡입구(16a)가 상기 냉기분사슬롯(13)에 대향하는 위치에 형성되어 있고, 이 흡입구(16a)는 저면판(30)의 내측에 형성되어 냉장고 기계실(40)과 연통하는 냉기이송덕트(16)와 연통되어 있다. 또한, 상기 흡입구(16a) 내에는 상기 냉기분사슬롯(13)으로부터 고속으로 분사된 냉기를 적극적으로 흡입하기 위한 흡입팬(15)이 장착되어 있다. 또한, 상기 냉기이송덕트(16) 내에는 기계실의 온기가 냉장실(50)내로 억류하는 것을 방지하기 위한 억류방지밸브(16b)가 개재되어 있다. 상기 냉기이송덕트(16)의 말단부에는 이 이송덕트(16)를 통해 공급된 냉기를 기계실(40)내의 고온발생부(예로써, 압축기(18))로 지향시키기 위한 냉기분사구(17)가 설치되어 있다. 따라서, 상기 냉기분사슬롯(13)으로부터 고속으로 분사되어 저면판(30)의 흡입구(16a)로 유입됨으로써 냉장실(50)의 전면에 냉기에 의한 에어커튼(14)을 형성한 냉기는 냉기이송덕트(16)를 통해 기계실(40) 내로 유입되어 기계실(40) 내의 압축기(18)를 냉각시키는데 이용된다.In addition, in the refrigerator bottom plate shown by reference numeral 30 in FIG. 1, a suction port 16a for sucking cold air injected from the cold air injection slot 13 faces the cold air injection slot 13. The suction port 16a is formed inside the bottom plate 30 and communicates with the cold air transfer duct 16 communicating with the refrigerator machine room 40. In addition, the suction port 16a is provided with a suction fan 15 for actively sucking cold air injected from the cold air injection slot 13 at high speed. In addition, the cold air transfer duct 16 is interposed with a detention prevention valve 16b for preventing the warmth of the machine room from being detained into the refrigerating chamber 50. At the distal end of the cold air transfer duct 16, a cold air injection port 17 for directing the cold air supplied through the transfer duct 16 to the high temperature generating unit (for example, the compressor 18) in the machine room 40 is installed. It is. Therefore, the cold air is injected from the cold air injection slot 13 at high speed and flows into the inlet 16a of the bottom plate 30 to form the air curtain 14 formed by cold air on the front surface of the refrigerating chamber 50. It enters into the machine room 40 via 16 and is used to cool the compressor 18 in the machine room 40.
위와 같은 구성의 에어커튼 형성장치는, 냉장고 도어(도시생략)의 개폐와 연동되도록 구성된 온/오프 스위치(19)에 의해 동작되도록 하는 것이 바람직하다. 즉, 냉장고 도어를 개방하면, 상기 스위치(19)가 중간간막이판(20)의 송풍팬(12)와 저면판(30) 상의 흡입팬(15)을 작동시킴으로써, 제1도 및 제2도에 도시한 바와 같이, 냉장실(50)의 전면에 냉기에 의한 에어커튼(14)을 형성할 수 있게 된다.Air curtain forming device of the above configuration, it is preferable to be operated by the on / off switch 19 configured to be linked to the opening and closing of the refrigerator door (not shown). That is, when the refrigerator door is opened, the switch 19 operates the blower fan 12 of the middle partition plate 20 and the suction fan 15 on the bottom plate 30, thereby providing the first and second views. As shown, the air curtain 14 by cold air can be formed in the front side of the refrigerating chamber 50. As shown in FIG.
제2도에 도시되어 있는 바와 같이, 중간간막이판(20)에 다수의 송풍팬(12)을 설치하여 냉장실(50)의 전면에 걸쳐 에어커튼(14)을 형성할 수 있도록 하고, 저면판(30)에는 하나의 흡입팬(30)을 설치한다.As shown in FIG. 2, a plurality of blowing fans 12 are installed in the middle partition plate 20 so that the air curtain 14 can be formed over the entire surface of the refrigerating chamber 50, and the bottom plate ( 30, one suction fan 30 is installed.
위의 설명과 같은 본 발명의 에어커튼 형성장치를 구비한 냉장고에 의하면 냉장고의 도어 개방시에 외기가 냉장고 내에 유입되는 것을 방지할 수 있고, 또한, 에어커튼을 형성한 냉기는 전술한 바와 같이 냉장고의 기계실내의 고온발생부를 냉각하는데 이용할 수 있으므로 압축기를 포함한 고온발생부를 냉각시키기 위한 별도의 냉각수단을 제거할 수 있는 효과가 있다.According to the refrigerator provided with the air curtain forming apparatus of the present invention as described above, it is possible to prevent outside air from flowing into the refrigerator when the door of the refrigerator is opened, and the cold air having the air curtain formed therein as described above. Since it can be used to cool the high temperature generating part in the machine room, there is an effect that can remove the separate cooling means for cooling the high temperature generating part including the compressor.
