본 발명의 구성과 작용을 좀더 구체적으로 설명하면, 도면 제 1 도는 종래의 냉장고(1)에 증설하여 공간을 확보한 별도의 진공냉장실(2)을 갖춘 것으로 외관 구조상 통기밸브(18)와 문손잡이(11) 그리고 뒷면의 몸체벽(3)내에 진공펌프(5)를 장착한 점이 종래의 냉장고(1)와 다른 것이다.Referring to the configuration and operation of the present invention in more detail, Figure 1 is a conventional refrigerator (1) by adding a separate vacuum refrigeration chamber (2) to secure a space in the appearance structure of the vent valve 18 and the door handle (11) The point of mounting the vacuum pump 5 in the body wall 3 on the back side is different from the conventional refrigerator 1.

도면 제 2 도는 본 발명의 구조와 구성요소들에 대하여 나타낸 것으로 이의 작용을 설명하면 최초 진공냉장실(2) 문(10)을 닫으면 눌림스위치(4)에 의하여 진공펌프(5)가 작동하고 이에 따라 진공냉장실(2) 내부의 기체분자가 강제로 배출되어 진공냉장실(2) 내부가 진공을 이루게 된다.2 is a view of the structure and the components of the present invention. When explaining the operation thereof, the vacuum pump 5 is operated by the push switch 4 when the door 10 of the first vacuum refrigerator compartment 2 is closed. Gas molecules in the vacuum refrigerating chamber 2 are forcibly discharged, and the inside of the vacuum refrigerating chamber 2 is vacuumed.

진공냉장실(2) 내부의 냉기유입은 종래의 냉장고(1)에서 연하여 구성되는 응축기를 통한 냉기증발기능의 냉각관(23)에 의하여 차겁게 되며, 이는 저면의 몸체벽(3)에 형성하고 진공냉장실(2) 내부가 밀봉되게 함과 동시에 냉기를 전달하는 냉각판(4)을 구성하여서 된 것이다.The cold air inflow inside the vacuum refrigerating chamber 2 is cooled by a cooling tube 23 having a cold air evaporation function through a condenser formed in a conventional refrigerator 1, which is formed on the body wall 3 of the bottom surface. The inside of the vacuum refrigerating chamber 2 is sealed, and the cooling plate 4 which delivers cold air is comprised.

진공냉장실(2) 내부는 진공상태인 10-2mmHg 정도 이하 또는 이상의 저압이므로 냉기가 더욱 빠르게 이동하여 전달되는 특징으로 종래의 냉동실이나 냉장실 보다 우수한 냉기발생 효율을 갖기도 한다.Since the inside of the vacuum refrigerating chamber 2 has a low pressure of about 10 −2 mmHg or less in a vacuum state, the cold air moves faster and is transferred, and thus, has an excellent cold air generating efficiency than the conventional freezer or refrigerating chamber.

진공냉장실(2)내에 저장된 식품류를 꺼낼 때는 외기를 유입하여 진공상태가 해제되게 하는 기능으로 1차 외기를 유입시키는 통기밸브(18)를 형성하며, 이는 누름버튼(20)을 눌러 외기가 유입되게 한다.When taking out the foodstuffs stored in the vacuum refrigerating chamber (2) to form a vent valve (18) for introducing the first outdoor air to the inlet of the outside air to release the vacuum state, which presses the push button (20) do.

또한 문손잡이(11)는 문(10)를 여는 기능과 2차 외기를 유입시키는 기능을 동시에 수행하며, 이는 1차 외기가 유입됨에도 불구하고 완전한 진공해제를 보장받지 못하는 현상에 대한 보완책인 것이다.In addition, the door handle 11 performs the function of opening the door 10 and the function of introducing the second outdoor air at the same time, which is a supplement to the phenomenon that the complete vacuum release is not guaranteed even though the first outdoor air is introduced.

다시 문(10)을 닫으면 눌림스위치(4)에 의한 진공펌프(5)가 작동되는 작용을 수행한다.When the door 10 is closed again, the vacuum pump 5 by the push switch 4 operates.

이와같은 기능의 구성체인 본 발명의 각 요소들에 대하여 나누어 설명하면, 눌림스위치(4)에 의하여 작동되는 진공펌프(5)에 유입되고 다시 배기관(8)과 배출구(9)를 통하여 외부로 배출된다.Each of the elements of the present invention, which is a component of such a function, is divided into the vacuum pump 5 operated by the push switch 4 and discharged to the outside through the exhaust pipe 8 and the outlet 9 again. do.

진공펌프(5)의 배기구마개(6)는 진공중 기체분자의 역류를 방지하는 역할을 한다. 통기밸브(18)는 문(10)의 중앙에 구멍을 뚫어 장착하는 것으로 도면 제 5 도와 같이 누름버튼(20), 밸브몸체(19), 요부(22), 스프링(15), 밸브마개(21)로 되어 누름버튼(20)을 누르면 밸브마개(21)가 밸브몸체(19)의 요부(22)로부터 이격되어 외기가 유입되며 외기유입이 끝나면 스프링(15)에 의해 누름버튼(20)이 복구된다.The exhaust plug 6 of the vacuum pump 5 serves to prevent backflow of gas molecules in the vacuum. Ventilation valve 18 is provided by drilling a hole in the center of the door 10, the push button 20, the valve body 19, the recessed portion 22, the spring 15, the valve plug 21 as shown in FIG. Press the push button 20, the valve stopper 21 is spaced from the main portion 22 of the valve body 19 so that the outside air flows in and the push button 20 is restored by the spring 15 after the inflow of the outside air. do.

도면 제 3 도는 나타내기 편리하게 하기 위한 문손잡이(11) 일대를 확대한 사시도이며, 이에 따른 도면 제 4 도에서와 같이 문손잡이(11)에 부설된 손잡이측 마개(12)와 문측 마개(13)등의 구조를 나타낸 것이다.FIG. 3 is an enlarged perspective view of a portion of the door handle 11 for convenience of display, and as shown in FIG. 4, the handle side stopper 12 and the door stopper 13 attached to the door handle 11 are enlarged. ) Is shown.

문손잡이(11)는 문(10)의 몸체 끝단에 구성되며 문(10)을 사람의 손으로 열때 문손잡이(11)가 젖혀지는 작용과 문(10)이 열리는 작용을 동시에 한다.The door handle 11 is configured at the end of the body of the door 10, and when the door 10 is opened by a human hand, the door handle 11 is flipped and the door 10 is opened at the same time.

문손잡이(11)는 나사공(17)에 의해 지지되며 사람의 손에 의해 젖혀지고 스프링(15)에 의해 복구된다.The door handle 11 is supported by the screw hole 17 and is retracted by the human hand and restored by the spring 15.

문(10)을 열때 문손잡이(11)를 당기면, 젖혀지면서 상기한 2차 외기가 유입되는데 이는 손잡이측 마개(12)와 문측 마개(13)가 이격되어 문측 마개(13) 중앙의 마개구멍(14)을 통해 외기유입구(16)를 따라 진공냉장실(2) 내부로 외기가 유입된다.Pulling the door handle (11) when opening the door (10), the second outside air is introduced while being flipped, which is the handle side stopper (12) and the door stopper (13) is separated from the stopper hole in the center of the door stopper (13) ( 14) the outside air flows into the vacuum refrigerating chamber 2 along the outside air inlet 16.

휠터(28)가 진공냉장실(2) 내부의 내기배출관(7)측과 통기밸브(18)측 그리고 문손잡이(11)측에 공히 형성된 것은 내기를 배출하거나 외기를 유입하는 과정에서 공기를 깨끗하게 걸러주기 위한 것이다.The filter 28 is formed on both the air exhaust pipe 7 side, the vent valve 18 side, and the door handle 11 side in the vacuum refrigerating chamber 2 to clean the air in the process of discharging the internal air or introducing the external air. It is to give.

진공냉장실(2) 내부가 진공되려면 문(10)이 확고히 닫혀지고 문(10)의 틈이 치밀하게 밀착되어야 하는데 이는 문(10)이 눌리는 힘을 갖게 하기 위해 문(10) 장석에 스프링을 형성하거나 가스켓(27) 취부구조를 개선하면 되는 것으로 본 발명에서는 세부구성을 생략하기로 한다.In order to vacuum the inside of the vacuum refrigerating chamber (2), the door (10) must be firmly closed and the gap of the door (10) must be tightly pressed, which forms a spring on the door (10) feldspar to give the door (10) a pressing force. In addition, since the gasket 27 mounting structure may be improved, a detailed configuration will be omitted in the present invention.

도면 제 2 도의 순환팬(26)은 냉각관(23)과 냉각판(24)에 의해 냉기가 진공냉장실(2) 내부에 전달됨에 따른 냉기의 순환을 위해 구성된 것이다.The circulation fan 26 of FIG. 2 is configured for circulation of the cold air as the cold air is transferred into the vacuum refrigerating chamber 2 by the cooling tube 23 and the cooling plate 24.

이상에서와 같이 구성된 본 발명은 종래의 냉장고(1)에 진공냉장실(2)이 부설됨에 따라 식품류를 보관하면 호기성 미생물(好氣性微生物)에 의한 부패를 지연시키고 또한 산화방지와 습기로부터 식품류를 보호할 수 있어서 장기간 냉장에 큰 효과를 얻을 수 있는 것이다.According to the present invention configured as described above, when the vacuum refrigerator compartment 2 is installed in the conventional refrigerator 1, the foodstuffs are stored to delay the decay due to aerobic microorganisms and to protect the foodstuffs from oxidation and moisture. It can be a great effect for long-term refrigeration.

또한 과일을 이용한 음식만들기나 김치 등을 만들때 첨가된 조미료가 짧은 시간내에 급속히 스며들어 맛을 내는 효과가 탁월한 기능을 제공하게 된 것이다.In addition, the seasoning added when making foods using kimchi or making kimchi, etc., quickly penetrates in a short time to provide an excellent effect.
