냉장고 및 그 제어방법Refrigerator and its control method

본 발명은 냉장고 및 그 제어방법에 관한 것으로서, 급속냉각실내의 물품의 수용여부를 감지하여 그 내부를 소정의 설정온도로 유지할 수 있도록 한 냉장고에 관한 것이다.The present invention relates to a refrigerator and a control method thereof. The present invention relates to a refrigerator configured to detect whether an article is accommodated in a rapid cooling chamber and to maintain the inside at a predetermined set temperature.

냉장고중에는, 도 7에서 볼 수 있는 바와 같이, 급속냉각실을 가지는 것도 제안되어 있다. 도면에서 볼 수 있는 바와 같이, 종래의 냉장고는, 상하로 구획된 한 쌍의 냉각실을 가지는 냉장고본체와, 냉장고본체의 전면에 설치되어 각 냉각실을 회동개폐시키는 냉장고도어를 가지고 있다. 냉장고본체(101)의 후면하단에는 냉매의 압축을 위한 압축기(106)가 설치되어 있으며, 냉동실(102) 및 냉장실(103)의 후방벽과 본체의 후벽사이에는 증발하는 냉매에 의해 주위공기를 냉각시키는 냉동실증발기(107) 및 냉장실증발기(108)가 각각 설치되어 있다.Among the refrigerators, as shown in Fig. 7, it is also proposed to have a rapid cooling chamber. As can be seen in the drawing, a conventional refrigerator has a refrigerator main body having a pair of cooling chambers divided up and down, and a refrigerator door installed at the front of the refrigerator main body to rotate and open and close each cooling chamber. A compressor 106 for compressing the refrigerant is installed at the lower rear end of the refrigerator body 101, and the ambient air is cooled by the refrigerant evaporating between the rear wall of the freezer compartment 102 and the refrigerating compartment 103 and the rear wall of the main body. The freezer compartment evaporator 107 and the refrigerator compartment evaporator 108 are respectively provided.

각 증발기(107,108)에는 송풍팬(109)이 인접하게 설치되어, 각 증발기(107,108) 주위에 형성되는 냉기를 냉동실(102)과 냉장실(103)로 각각 공급한다. 냉장실(103) 내부에는 냉장실증발기(108)에서 발생하는 냉기를 송풍하는 송풍팬(109)과 인접한 위치에 급속냉각실(110)이 마련되어 있으며, 저장품을 층상으로 저장할 수 있도록 복수의 수납선반(111)에 의해 내부공간이 상하로 구획되어 있고, 냉장실(103)의 하부에는 야채 및 과일 등을 보관할 수 있도록 야채저장실(112)이 마련되어 있다. 급속냉각실(110)의 온도는 냉장실(103)의 온도보다 상대적으로 소정 저온으로 유지되고, 야채저장실(112)의 온도는 냉장실(103)의 온도보다 소정 고온으로 유지된다.A blowing fan 109 is provided adjacent to each evaporator 107, 108 to supply cold air formed around each evaporator 107, 108 to the freezing chamber 102 and the refrigerating chamber 103, respectively. In the refrigerating chamber 103, a rapid cooling chamber 110 is provided at a position adjacent to the blowing fan 109 for blowing cold air generated in the refrigerating chamber evaporator 108, and a plurality of storage shelves 111 to store stored items in layers. The inner space is divided up and down by the upper side, and the vegetable storage room 112 is provided in the lower part of the refrigerating room 103 so that vegetables and fruits may be stored. The temperature of the rapid cooling chamber 110 is maintained at a predetermined temperature relatively lower than the temperature of the refrigerating chamber 103, the temperature of the vegetable storage chamber 112 is maintained at a predetermined temperature higher than the temperature of the refrigerating chamber 103.

그런데, 이러한 종래의 냉장고에서는, 급속냉각실(110)의 온도조절이 단순히 증발기와 인접하게 설치되어 있는 송풍팬(109)에 의해 이루어진다. 특히, 송풍팬(109)의 작동은 급속냉각실(110)내의 온도나 물품수용여부에 관계없이 냉장실(103)내의 온도에 따라 단속되며, 이에 의해, 급속냉각실내에 효과적인 급속냉각이 이루어지지 못한다는 문제점이 있다.By the way, in such a conventional refrigerator, the temperature control of the rapid cooling chamber 110 is simply performed by the blowing fan 109 provided adjacent to the evaporator. In particular, the operation of the blower fan 109 is intermittent according to the temperature in the refrigerating chamber 103 regardless of the temperature in the rapid cooling chamber 110 or whether the article is accommodated, whereby the rapid cooling in the rapid cooling chamber is not effective. Has a problem.

따라서, 본 발명의 목적은, 종래의 이러한 문제점들을 고려하여, 급속냉각실내의 물품수용여부에 따라 급속냉각실내를 소정의 설정온도로 유지할 수 있도록 한 냉장고 및 냉장고의 제어방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a control method of a refrigerator and a freezer capable of maintaining the inside of the rapid cooling chamber at a predetermined set temperature according to whether or not the article is accommodated in the rapid cooling chamber.

As described with reference to FIG. 7 of the related art, the refrigerator 1 includes a pair of refrigerator doors 11 which rotate and open the refrigerator body 3 and the respective cooling chambers 5 and 7 of the refrigerator body 3. 13) Therefore, the description about the whole structure of the refrigerator 1 is replaced with what was mentioned above, In the following, the rapid cooling chamber 10 which has a structural difference is demonstrated concretely.

급속냉각실(21)은 사각통형상을 가지며, 그 배면에는 증발기(15) 주위에 형성된 냉기의 유동을 안내하는 냉기덕트(17)의 냉기토출구와 연통하는 급속냉각토출구(23)가 형성되어 있다. 급속냉각토출구(23)의 하부에는 급속냉각토출구(23)를 개폐시킴으로써, 급속냉각실내의 온도를 조절가능한 온도조절장치(31)가 설치되어 있다. 그리고, 급속냉각실(21)의 하부판(25)에는 냉각실내와 연통하는 다수의 냉기유출구(26)가 형성되어 있고, 그 상면 즉, 급속냉각실(21)의 바닥면에는 물품수용여부를 감지하는 누름스위치(29)가 설치되어 있다.The rapid cooling chamber 21 has a rectangular cylinder shape, and on the rear thereof, a rapid cooling discharge port 23 communicating with the cold air discharge port of the cold air duct 17 for guiding the flow of cold air formed around the evaporator 15 is formed. . In the lower part of the quick cooling discharge port 23, a temperature control device 31 capable of adjusting the temperature in the quick cooling chamber is provided by opening and closing the quick cooling discharge port 23. In addition, a plurality of cold air outlets 26 are formed in the lower plate 25 of the rapid cooling chamber 21 and communicate with the inside of the cooling chamber. The push switch 29 is provided.

온도조절장치(31)는, 급속냉각토출구(23)를 회동개폐가능하게 설치되는 댐퍼(35)와, 댐퍼(35)를 개폐시키는 댐퍼구동부(33), 그리고, 급속냉각실내 온도를 감지하는 도시않은 온도감지부로 구성되어 있다. 댐퍼구동부(33)의 전면에는 급속냉각실(21)의 내부로 노출되어, 온도조작가능한 온도설정노브(37)가 결합되어 있다. 한편, 누름스위치(29)는, 물품의 안착시 누름유지되고 물품의 인출시 원상복귀되는 형태로 구성되어 있다. 도면에서는 설명의 용이함을 위하여 누름스위치가 실제보다 과장되어 도시되어 있다.The temperature control device 31 is a damper 35 to which the rapid cooling discharge port 23 is rotatably opened and closed, a damper driver 33 for opening and closing the damper 35, and a city for sensing the temperature in the rapid cooling chamber. It consists of a temperature sensing unit. The front surface of the damper driver 33 is exposed to the inside of the rapid cooling chamber 21, the temperature setting knob 37 that can be operated temperature is coupled. On the other hand, the push switch 29 is configured in such a way that it is held in place when the article is settled and returned to its original shape when the article is taken out. In the drawings, the push switch is exaggerated than actual for ease of explanation.

이와 같은 구성을 가지는 본 냉장고(1)는, 도 3에서 볼 수 있는 바와 같이, 급속냉각실내의 온도를 설정할 수 있는 온도설정노브(37)와, 급속냉각실내의 온도를 감지하는 온도감지부(39), 급속냉각토출구(23)의 개구에 개폐가능하게 설치된 댐퍼(35), 그리고 댐퍼(35)를 개폐시키는 댐퍼구동부(33)를 가진다. 여기에, 급속냉각실내에 물품수용여부를 감지하는 누름스위치(29)와, 댐퍼구동부(33)를 통해 댐퍼(35)를 개폐시키는 제어부(41)를 더 포함하고 있다.As shown in FIG. 3, the refrigerator 1 having such a configuration includes a temperature setting knob 37 capable of setting a temperature in the rapid cooling chamber, and a temperature sensing unit for sensing a temperature in the rapid cooling chamber ( 39, a damper 35 provided to be opened and closed at the opening of the rapid cooling discharge port 23, and a damper driver 33 for opening and closing the damper 35. The apparatus further includes a push switch 29 for sensing whether the article is accommodated in the rapid cooling chamber, and a controller 41 for opening and closing the damper 35 through the damper driver 33.

한편, 도 4는 본 발명에 따른 냉장고의 제어방법을 설명하기 위한 순서도이다. 제어부(41)는 누름스위치(29)로부터의 신호에 기초하여 급속냉각실(21)의 물품수용여부를 인식한다(S1). 도 5에서 볼 수 있는 바와 같이, 급속냉각실내에 물품이 수용되지 아니한 경우에는, 누름스위치(29)는 누름해제위치에 배치된다. 이때, 냉장고(1)는 냉각실내의 온도에 따른 제어방법으로 작동되며, 이에 의해 냉각실내는 소정의 설정온도로 유지된다.On the other hand, Figure 4 is a flow chart for explaining the control method of the refrigerator according to the present invention. The controller 41 recognizes whether or not the article is accommodated in the rapid cooling chamber 21 based on the signal from the push switch 29 (S1). As can be seen in FIG. 5, when the article is not accommodated in the rapid cooling chamber, the push switch 29 is disposed in the push release position. At this time, the refrigerator 1 is operated by a control method according to the temperature in the cooling chamber, whereby the cooling chamber is maintained at a predetermined set temperature.

이러한 작동중에, 도 6에서 볼 수 있는 바와 같이, 급속냉각실내에 수용되는 물품 즉, 병에 의해 누름스위치(29)가 누름유지되면, 제어부(41)는 우선, 온도감지부(39)로 부터의 온도신호에 기초하여 급속냉각실내의 온도를 감지한다(S3). 그래서, 급속냉각실내의 온도가 소정의 설정온도에 대한 기준허용값 이상을 경우(S4), 댐퍼구동부(33)를 통해 댐퍼(35)를 개방시킨다(S5). 그러면, 개방된 급속냉각토출구(23)를 통해 냉기덕트(17)로 부터의 냉기가 급속냉각실내로 유입된다. 그런 다음, 급속냉각실내의 온도가 소정의 설정온도에 대한 기준허용값 이하로 되었을 때, 댐퍼구동부(33)를 통해 댐퍼(35)를 폐쇄방향으로 회동시킨다(S6).During this operation, as shown in FIG. 6, when the push switch 29 is held by an article accommodated in the rapid cooling chamber, that is, a bottle, the controller 41 firstly starts from the temperature sensing unit 39. The temperature in the rapid cooling chamber is detected based on the temperature signal of (S3). Thus, when the temperature in the rapid cooling chamber is equal to or greater than the reference allowable value for the predetermined set temperature (S4), the damper 35 is opened through the damper driver 33 (S5). Then, the cold air from the cold air duct 17 is introduced into the rapid cooling chamber through the open rapid cooling discharge port 23. Then, when the temperature in the rapid cooling chamber is lower than the standard allowable value for the predetermined set temperature, the damper 35 is rotated in the closing direction through the damper driver 33 (S6).

이 후, 누름스위치(29)가 누름유지된 상태가 지속되는 경우, 다시, 급속냉각실의 온도에 따라 댐퍼의 개폐작동이 단속되고, 사용자가 물품을 인출시켜 누름스위치(29)가 해제위치에 배치되면, 정상적인 작동을 실시한다.After that, when the state in which the push switch 29 is pressed and held continues, the damper opening and closing operation is interrupted again according to the temperature of the quick cooling chamber, and the user pulls out the article so that the push switch 29 is in the release position. If deployed, perform normal operation.

이상 설명한 바와 같이, 본 발명에 따른 냉장고 및 냉장고의 제어방법에 따르면, 급속냉각실내의 물품수용여부에 따라 급속냉각실내가 소정의 설정온도로 유지되므로, 물품의 보관상태가 양호하게 된다.As described above, according to the control method of the refrigerator and the refrigerator according to the present invention, since the inside of the rapid cooling chamber is maintained at a predetermined set temperature according to whether the article is accommodated in the rapid cooling chamber, the storage state of the article is improved.
