일반적으로 김치 냉장고는 기존의 일반적인 냉장고와는 달리, 김치와 같은 발효 음식물을 적절하게 숙성시켜 음식물의 맛을 보다 더 향상시킬 수 있도록 하는 것으로서, 음식물을 적절히 숙성시키거나 맛을 지속적으로 유지하는데 주로 사용된다. 이러한 김치 냉장고는 냉각 방식에 따라 크게 간냉식 및 직냉식으로 구분되며, 김치 냉장고는 종래의 통상적인 김치 숙성 원리, 즉 땅 속 김치독의 김치 숙성 시간과 온도에 의한 원리에 착안한 것이다.In general, unlike conventional refrigerators, kimchi refrigerators are used to ferment fermented foods such as kimchi to improve the taste of foods more appropriately, and are mainly used to properly ripen foods or maintain the taste. do. These kimchi refrigerators are classified into a simple cooling method and a direct cooling method according to a cooling method, and the kimchi refrigerator focuses on a conventional kimchi ripening principle, that is, a principle based on the kimchi ripening time and temperature of the kimchi poison in the ground.

이러한 일반적인 구조를 갖는 김치냉장고는 도 1 내지 도 3에 도시한 바와 같이 상향 개구된 상부저장실(13)과 전면으로 개방된 하부저장실(17)이 각각 형성되어 있는 본체(11)와, 상부저장실(13)을 개폐할 수 있도록 본체(11)에 힌지결합되는 상부저장실도어(15)와, 하부저장실(17)에 본체(11)의 전후방향을 따라 인출 가능하게 수납되는 드로어(19)를 구비하고 있다.Kimchi refrigerator having such a general structure as shown in Figures 1 to 3, the main storage 11 and the upper storage chamber is formed with the upper storage chamber 13 is opened upwardly and the lower storage chamber 17 open to the front, respectively ( 13 is provided with an upper storage door 15 hinged to the main body 11 so that the main body 11 can be opened and closed, and a drawer 19 that is retractably accommodated in the lower storage chamber 17 along the front and rear directions of the main body 11. have.

상기 본체(11)의 상측면에는 상측커버(12)가 복개되어 상부저장실(13)에 통하는 개구부(13a)를 형성한다.The upper cover 12 is covered on the upper side of the main body 11 to form an opening 13a through the upper storage chamber 13.

드로어(19)의 전면에는 하부저장실(17)을 개폐할 수 있도록 도어(20)가 일체로 형성되어 있으며, 드로어(19)의 양 측부 및 하부저장실(17)의 양 내벽(18)에는 드로어(19)가 용이하게 인출 및 수납될 수 있도록 레일(21)이 구비되어 있다. 본체(11)의 전면에는 드로어(19)의 도어(20)에 접촉되며 하부저장실(17)에 통하는개구부(17a)를 형성한다.The front of the drawer 19, the door 20 is integrally formed to open and close the lower storage chamber 17, the drawer (19) on both sides of the drawer 19 and both inner walls (18) of the lower storage chamber (17) The rail 21 is provided so that 19) can be easily taken out and stored. An opening 17a is formed on the front surface of the main body 11 in contact with the door 20 of the drawer 19 and communicates with the lower storage chamber 17.

상측커버(12)에 형성된 개구부(13a)와 하부저장실(17)에 통하는 개구부(17a)의 주변에는 히터(36)가 장착되어 개구부(17a) 주변의 온도를 상온으로 유지시켜 대기중의 증기가 응결되지 않도록 한다.A heater 36 is mounted around the opening 13a formed in the upper cover 12 and the opening 17a through the lower storage chamber 17 to maintain the temperature around the opening 17a at room temperature to allow vapor in the atmosphere. Do not condense.

상기 상부저장실(13) 및 하부저장실(17)이 일정온도 이하로 유지되도록 하는 냉각사이클은 도 4에 도시한 바와 같이 저온 저압의 기체냉매를 압축하여 고온 고압의 기체냉매로 변화시키는 압축기(31)와, 압축기(31)에 의해 변환된 고온 고압의 기체냉매를 고온 고압의 액체냉매로 응축하는 응축기(32)와, 응축기(32)를 지난 액체냉매의 흐름을 제어하는 삼방밸브(33)와, 삼방밸브(33)에 연결되어 응축기(32)를 지난 고온 고압의 액체냉매를 공급받아 저온 저압의 액체냉매로 변환하는 모세관(34)과, 모세관(34)을 지난 저온 저압의 액체냉매는 냉각기(35)를 지나면서 저온 저압의 기체냉매로 변화되면서 증발하여 주변의 공기를 냉각시키므로 냉기가 발생된다.As shown in FIG. 4, the cooling cycle for maintaining the upper storage chamber 13 and the lower storage chamber 17 below a predetermined temperature compresses the gas refrigerant of low temperature and low pressure to change the gas refrigerant of high temperature and high pressure into a compressor 31. A condenser 32 for condensing the high temperature and high pressure gas refrigerant converted by the compressor 31 into a high temperature and high pressure liquid refrigerant, a three-way valve 33 for controlling the flow of the liquid refrigerant passing through the condenser 32, Capillary tube 34, which is connected to the three-way valve 33 and receives the high temperature and high pressure liquid refrigerant passing through the condenser 32, is converted into a low temperature low pressure liquid refrigerant, and the low temperature low pressure liquid refrigerant passing through the capillary tube 34 is a cooler ( As it passes through 35), it is transformed into a low-temperature low-pressure gas refrigerant and evaporates to cool the surrounding air.

The front surface of the main body 11 forms an opening 17a in contact with the door 20 of the drawer 19 and communicating with the lower storage chamber 17.

상기 상부저장실(13) 및 하부저장실(17)이 일정온도 이하로 유지되도록 하는 냉각사이클은 도 6에 도시한 바와 같이 저온 저압의 기체냉매를 압축하여 고온 고압의 기체냉매로 변화시키는 압축기(131)와, 압축기(131)에 의해 변환된 고온 고압의 기체냉매를 고온 고압의 액체냉매로 응축하는 응축기(132)와, 응축기(132)를 지난 고온 고압의 액체냉매를 안내하는 응결방지관(136)과, 응결방지관(136)을 지난 액체냉매의 흐름을 제어하는 삼방밸브(133)와, 삼방밸브(133)에 연결되어 응축기(132)를 지난 고온 고압의 액체냉매를 공급받아 저온 저압의 액체냉매로 변환하는 모세관(134)과, 모세관(134)을 지난 저온 저압의 액체냉매가 냉각기(135)를 지나면서 저온 저압의 기체냉매로 변화되면서 증발하여 주변의 공기를 냉각시키므로 냉기가 발생된다.The cooling cycle for maintaining the upper storage chamber 13 and the lower storage chamber 17 below a predetermined temperature is a compressor 131 for compressing a low-temperature low-pressure gas refrigerant to a high-temperature high-pressure gas refrigerant as shown in FIG. And a condenser 132 for condensing the high temperature and high pressure gas refrigerant converted by the compressor 131 into a high temperature and high pressure liquid refrigerant, and a condensation preventing tube 136 for guiding the high temperature and high pressure liquid refrigerant passing through the condenser 132. And a three-way valve 133 for controlling the flow of the liquid refrigerant passing through the condensation preventing pipe 136 and a high-temperature and high-pressure liquid refrigerant connected to the three-way valve 133 and passing through the condenser 132 to receive a liquid of low temperature and low pressure. The low temperature and low pressure liquid refrigerant passing through the capillary tube 134 and the capillary tube 134 is converted into a low temperature low pressure gas refrigerant while passing through the cooler 135 to cool the surrounding air.

상기 응결방지관(136)의 일측은 응축기(132)에 연결되어 응축된 고온 고압의 액체냉매를 공급받고, 상측커버(12)에 형성된 개구부(13a) 주변과 하부저장실(17)에 접하는 개구부(17a)의 주변에 권선되며, 그 타측은 삼방밸브(133)에 연결되는 구조로 형성된다.One side of the condensation preventing tube 136 is connected to the condenser 132 is supplied with the condensation of the high-temperature and high-pressure liquid refrigerant, the opening (13a) surrounding the opening 13a formed in the upper cover 12 and the lower storage chamber 17 ( Winding around the 17a), the other side is formed in a structure that is connected to the three-way valve 133.
