Description

한 쌍의 특선실을 구비한 냉장고{REFRIGERATOR WITH A COUPLE OF SOFT-FREEZING ROOMS}REFRIGERATOR WITH A COUPLE OF SOFT-FREEZING ROOMS}

본 발명은, 한 쌍의 특선실을 구비한 냉장고에 관한 것으로서, 보다 상세하게는, 냉동실 및 냉장실과 다른 온도로 음식물을 냉각 및 유지시킬 수 있으며 냉기공급이 신속하여 음식물의 선도를 높게 유지할 수 있을 뿐만 아니라, 하측에 배치된 특선실의 온도를 특선실 또는 냉장실 온도에 대응되게 선택적으로 절환할 수 있어 부하에 신축적인 대응이 가능하도록 한 한 쌍의 특선실을 구비한 냉장고에 관한 것이다.The present invention relates to a refrigerator having a pair of special chambers, and more particularly, to cool and maintain food at a temperature different from that of a freezer compartment and a refrigerating compartment, and to quickly maintain a freshness of food by supplying cold air quickly. In addition, the present invention relates to a refrigerator having a pair of specially selected chambers capable of selectively changing the temperature of the specially arranged chamber disposed at the lower side to correspond to the specially selected chamber or the refrigerating chamber temperature so as to be able to flexibly respond to the load.

일반적으로 냉장고는 음식물을 저온저장하기 위한 장치로서, 통상 비교적 낮은 온도에서 음식물을 동결저장하는 냉동실과 상대적으로 높은 온도에서 음식물을 냉장상태로 저장하는 냉장실을 구비한다. 냉동실은 통상 -18℃ 이하의 냉각온도를 유지하며, 냉장실은 2℃ 를 전후로 한 냉각온도 범위를 가진다.In general, a refrigerator is a device for low temperature storage of food, and includes a freezer compartment for freezing and storing food at a relatively low temperature and a refrigerating compartment for storing food at a relatively high temperature. The freezing chamber usually maintains a cooling temperature of -18 ° C or lower, and the refrigerating chamber has a cooling temperature range around 2 ° C.

어육류(漁肉類) 등은 통상 냉동실에 보관하게 되는데, 그럴 경우 해동에 많은 시간이 소요되어 많은 불편이 따르게 되며, 특히 육류 등을 비교적 짧은 시간, 예를 들면 수시간 내지 십수시간 정도로 보관하고자 할 경우에는 적절히 보관할 장소가 없는 실정이다.Fish and meat (漁 肉類) is usually stored in the freezer, in which case it takes a lot of time to thaw, causing a lot of inconvenience, especially if you want to store meat for a relatively short time, for example several hours to several ten hours There is no place for proper storage.

최근에는 이러한 점을 고려하여, 냉장실의 내부에 소위 신선실 또는 싱싱고 등으로 불리는 별도의 특선실을 마련하여 어류, 육류 등을 보관하도록 한 냉장고들이 고안되어 있다.In recent years, in consideration of this point, refrigerators have been devised to store fish, meat, and the like by providing a special special room called a fresh room or a singso, etc. inside the refrigerating compartment.

그런데, 이러한 종래의 특선실이 구비된 냉장고에 있어서는, 특선실이 통상 -1℃를 전후로 해서 운전이 이루어지기 때문에, 냉기의 공급시와 중단시의 온도편차에 기인하여 음식물의 세포속의 수분이 얼었다 녹았다를 반복하게 되어 음식물의 특유의 풍미를 저해하게 된다고 하는 문제점이 있다.By the way, in the refrigerator equipped with such a conventional specialty room, since the specialty room normally operates around -1 degreeC, the water | moisture content of the food cell frozen in water by the temperature deviation at the time of supplying and stopping cold air. There is a problem in that it is to repeat the melted to inhibit the unique flavor of the food.

또한, 보관할 음식물이 많은 경우에는 일부를 냉동실에 보관하여야 하므로 보관도중 음식물이 완전 결빙되어 조리시 해동을 필요로 하게 되어 사용에 많은 불편이 따르게 된다고 하는 문제점이 있다.In addition, when there is a lot of food to be stored, part of the food should be stored in the freezer, so that during the storage of the food is completely frozen, there is a problem that requires a lot of inconvenience in use because it requires thawing during cooking.

따라서, 본 발명의 목적은, 냉동실 및 냉장실과 다른 온도로 음식물을 냉각 및 유지시킬 수 있으며 냉기공급이 신속하여 음식물의 선도를 높게 유지할 수 있을 뿐만 아니라, 하측에 배치된 특선실의 온도를 특선실 또는 냉장실 온도에 대응되게 선택적으로 절환할 수 있어 부하에 신축적인 대응이 가능하도록 한 한 쌍의 특선실을 구비한 냉장고를 제공하는 것이다.Accordingly, an object of the present invention is to cool and maintain the food at a different temperature from the freezer compartment and the refrigerating compartment, and to supply the cold air quickly to maintain the freshness of the food, and to select the temperature of the specially arranged chamber located at the lower side. Alternatively, the present invention provides a refrigerator having a pair of specially selected rooms that can be selectively switched to correspond to the temperature of the refrigerator compartment so that the load can be flexibly responded to the load.

상기 목적은, 본 발명에 따라, 상하방향을 따라 형성된 격벽을 사이에 두고 냉동실 및 냉장실이 각각 형성되어 있는 냉장고에 있어서, 단열부재로 일측이 개구된 통형상을 가지고 상기 냉장실의 내부에 배치되어 상기 냉동실 및 냉장실과 상호 다른 온도로 음식물을 냉각하는 제1특선실을 형성하며, 상기 격벽과 접촉되는 측벽에 형성된 제1흡기구와 저부면에 관통된 제1배출구를 구비한 제1케이싱과; 상기 제1흡기구와 상호 연통되게 격벽을 관통하여 형성되는 냉기공급부와; 상기 냉기공급부를 통해 상기 냉동실의 냉기를 상기 제1케이싱의 내부로 흡입하는 흡입팬과; 단열부재로 일측이 개구된 통형상을 가지고 상기 제1케이싱의 하측에 배치되어 제2특선실을 형성하며 상부면에 관통형성된 제2흡기구와, 일측에 내부의 냉기를 배출할 수 있도록 제2배출구를 구비한 제2케이싱과; 상기 제1케이싱 및 제2케이싱의 내부온도를 감지하는 제1온도감지센서 및 제2온도감지센서와; 일단은 상기 제1배출구에 연결되고 타단은 상기 제2흡기구와 상호 연통되게 연결되며 일측에 제3배출구가 형성된 상하연결덕트와; 일측연부가 공동회동축에 일체로 회동가능하게 결함됨과 아울러 상호 내각이 직각을 이루도록 형성되어 상기 상하연결덕트 및 상기 제3배출구중 적어도 어느 하나가 차단되도록 배치되는 제1개폐판부 및 제2개폐판부를 구비한 개폐판과; 상기 개폐판을 회동구동시키는 개폐판구동모터와; 상기 제1케이싱 및 제2케이싱의 냉각온도를 각각 설정하는 제1 및 제2특선실온도설정버튼과; 상기 제1 및 제2특선실온도설정버튼에 의해 설정된 온도 및 상기 제1 및 제2온도감지센서의 감지결과에 기초하여 상기 개폐판구동모터를 제어하는 제어부를 포함하는 것을 특징으로 하는 한 쌍의 특선실을 구비한 냉장고에 의해 달성된다.According to the present invention, in the refrigerator in which the freezer compartment and the refrigerating compartment are formed, respectively, with partition walls formed along the up and down direction, the refrigerator has a tubular shape, one side of which is opened as a heat insulating member, and is arranged inside the refrigerating compartment. A first casing which forms a first special chamber for cooling food at a temperature different from that of the freezer compartment and the refrigerating compartment, the first casing having a first intake formed in a side wall contacting the partition wall and a first outlet formed in the bottom surface; A cold air supply unit formed through the partition wall to communicate with the first intake port; A suction fan configured to suck cold air from the freezing compartment into the first casing through the cold air supply unit; A second inlet having a tubular shape, one side of which is opened as a heat insulating member, disposed below the first casing to form a second special chamber, and formed through the upper surface, and a second outlet for discharging the cold air to one side; A second casing having a; A first temperature sensor and a second temperature sensor for sensing internal temperatures of the first and second casings; An upper and lower connection ducts having one end connected to the first outlet and the other end connected to each other in communication with the second inlet and having a third outlet formed at one side thereof; The first opening plate and the second opening and closing plate are formed so that one side edge is integrally rotatable in the joint pivot shaft and mutually perpendicular to each other so that at least one of the vertical connecting duct and the third discharge port is blocked. And opening and closing plate provided with; An opening and closing plate driving motor for driving the opening and closing plate; First and second special room temperature setting buttons for setting cooling temperatures of the first and second casings, respectively; And a control unit for controlling the opening and closing plate driving motor based on the temperature set by the first and second special room temperature setting buttons and the detection result of the first and second temperature sensing sensors. This is achieved by a refrigerator with specialty rooms.

여기서, 상기 제어부는 상기 제1온도감지센서 및 제2온도감지센서의 감지결과, 상기 제1특선실 및 제2특선실의 냉각온도조건이 미충족된 경우, 상기 제1케이싱 및 제2케이싱이 상호 연통됨과 동시에 상기 제3배출구가 차단되는 위치로 상기 제1개폐판 및 제2개폐판이 회동하도록 상기 개폐판구동모터를 제어하는 것이 바람직하다.Here, when the cooling temperature conditions of the first special chamber and the second special chamber are not satisfied as a result of the detection of the first temperature sensor and the second temperature sensor, the first casing and the second casing mutually cross each other. It is preferable to control the opening and closing plate driving motor so that the first opening and closing plate and the second opening and closing plate rotate in a position where the third outlet is blocked while being in communication with each other.

그리고, 상기 제어부는 상기 제1온도감지센서 및 제2온도감지센서의 감지결과, 상기 제2특선실의 냉각온도조건이 충족되고 상기 제1특선실의 냉각온도조건이 미충족된 경우, 상기 제2흡기구가 차단되고 상기 제3배출구가 개방되는 위치로 상기 제1개폐판 및 제2개폐판이 회동하도록 상기 개폐판구동모터를 제어하는 것이 효과적이다.The control unit is further configured to control the second temperature when the cooling temperature condition of the second special chamber is satisfied and the cooling temperature condition of the first special chamber is not satisfied, as a result of the detection of the first temperature sensor and the second temperature detecting sensor. It is effective to control the opening and closing plate driving motor so that the first opening and closing plate and the second opening and closing plate rotate to a position where the intake port is blocked and the third discharge port is opened.
