Blowing fans 21 and 23 for blowing cold air are provided adjacent to the evaporators 17 and 19, respectively.
한편, 도 2는 본 발명에 따른 냉장고의 제어블록도이고, 도 3은 본 발명에 따른 온도제어방법의 흐름도이다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 냉장고에는 사용자가 취침운전을 선택할 수 있는 취침운전선택버튼(25)과, 냉동실(5) 및 냉장실(7)의 온도를 검출하는 온도감지부(27)가 마련되어 있으며, 취침운전선택버튼(25)에 의해 취침운전이 선택된 경우, 온도감지부(27)의 온도검출값과 기 설정된 취침제어온도를 비교하여 압축기(15) 및 송풍팬(21,23)의 구동을 제어하는 제어부(29)가 마련되어 있다.2 is a control block diagram of a refrigerator according to the present invention, and FIG. 3 is a flowchart of a temperature control method according to the present invention. As shown in these drawings, the refrigerator according to the present invention includes a bed operation selection button 25 through which a user can select a bed operation, and a temperature sensing unit 27 for detecting temperatures of the freezing chamber 5 and the refrigerating chamber 7. If the sleep operation is selected by the sleep operation selection button 25, the compressor 15 and the blower fan 21, 23 by comparing the temperature detection value of the temperature sensing unit 27 with the preset sleep control temperature. The control part 29 which controls the drive of () is provided.
일반적으로 냉동실 및 냉장실의 온도제어를 위해서는 서로 상이한 여러 온도대역별로 유지시키는 다양한 운전모드를 가진다. 취침운전선택버튼(25)에 의해 취침운전이 선택되면, 제어부(29)에 의해 다양한 운전모드 중, 약냉운전모드로 운전되며, 제어부(29)에 기 설정된 취침제어온도는 약냉운전모드의 최상한온도이다.In general, the temperature control of the freezer compartment and the refrigerating compartment has a variety of operating modes that are maintained for each different temperature band. When the sleep operation is selected by the sleep operation selection button 25, the controller 29 is operated in the low temperature cold operation mode among the various operation modes, and the sleep control temperature preset in the control unit 29 is the best of the low temperature cooling mode. Temperature.
이상과 같은 구성에 의하여, 사용자가 야간에 취침을 하기 전에, 취침운전선택버튼(25)을 ON하여 취침운전을 선택하게 되면(S1), 제어부(29)에서는 냉동실(5) 및 냉장실(7)의 온도감지부(27)로부터 감지하여 입력으로 받아들이게 되며, 제어부(29)에 기 입력된 취침제어온도와 비교하게 된다(S2). 만약, 취침운전 중인 경우, 취침운전선택버튼(25)을 누르게 되면, 취침운전이 OFF 되어 정상운전이 가동하는 것으로, 취침운전 전에 가동되던 운전모드로 가동하게 된다(S3).By the above configuration, before the user goes to bed at night, when the user selects the sleep operation by turning on the sleep operation selection button 25 (S1), the control unit 29 controls the freezer compartment 5 and the refrigerating compartment 7. The temperature is detected by the temperature sensing unit 27 is received as an input, and compared with the sleep control temperature previously input to the control unit 29 (S2). If the sleep operation is pressed, when the sleep operation selection button 25 is pressed, the sleep operation is turned off, and the normal operation is started, and the operation is performed in the operation mode that was operated before the sleep operation (S3).
먼저, 냉동실(5)의 온도가 기 입력된 냉동에 해당하는 냉동실측 취침제어온도보다 높게되면, 제어부(29)에서는 압축기(15)와 송풍팬(21,23)을 가동시켜 약냉운전모드로 냉동시스템을 운전하게 된다(S4). 만약, 냉동실(5)의 온도가 기 입력된 냉동실측 취침제어온도보다 낮게되면, 제어부(29)에서는 냉장실(7)의 온도와 기 입력된 냉장에 해당하는 냉장실측 취침제어온도와 비교하게 된다(S5).First, when the temperature of the freezing chamber 5 is higher than the freezing chamber side sleep control temperature corresponding to the previously input freezing, the control unit 29 operates the compressor 15 and the blowing fans 21 and 23 to freeze in the weak cooling operation mode. The system is operated (S4). If the temperature of the freezer compartment 5 is lower than the previously input freezing chamber side sleep control temperature, the controller 29 compares the temperature of the refrigerating compartment 7 with the refrigerating compartment side sleep control temperature corresponding to the input refrigeration ( S5).
냉장실(7)의 온도가 기 입력된 냉장실측 취침제어온도보다 높게 되면, 제어부(29)에서는 약냉운전모드로 압축기(15)와 송풍팬(21,23)을 가동시키게 되며(S6), 만약, 냉장실(7)의 온도가 기 입력된 냉장실측 취침제어온도보다 낮게 되면 취침운전에 들어가게 된다(S7).When the temperature of the refrigerating chamber 7 is higher than the refrigerating-side sleeping control temperature inputted, the control unit 29 operates the compressor 15 and the blowing fans 21 and 23 in the weak cooling operation mode (S6). When the temperature of the refrigerating chamber (7) is lower than the input of the refrigerating chamber side sleep control temperature is entered (S7).
취침운전 중에도, 제어부(29)에서는 냉동실(5) 및 냉장실(7)의 온도를 기 설정된 냉동실 및 냉장실측 취침제어온도와 계속 비교하여 냉동실(5) 및 냉장실(7)의 온도를 적절하게 유지시킨다.Even during the sleep operation, the control unit 29 continuously compares the temperatures of the freezing chamber 5 and the refrigerating chamber 7 with the preset freezing chamber and refrigerating chamber side control temperature to maintain the temperatures of the freezing chamber 5 and the refrigerating chamber 7 properly. .
이와 같이, 야간에 사용자가 선택버튼을 통해 용이하게 취침운전을 선택할 수 있어 냉동실 및 냉장실을 약냉운전모드로 운전함에 따라 소음으로 인한 수면방해와 냉동실 및 냉장실의 과도한 온도 상승을 억제시킬 수 있다.As such, the user can easily select the bedtime operation through the selection button at night, thereby suppressing sleep disturbance due to noise and excessive temperature rise of the freezer and the refrigerating compartment as the freezer and the refrigerating compartment are operated in the weak cooling operation mode.
이상에서 설명한 바와 같이, 본 발명에 따르면, 사용자가 취침운전선택버튼을 이용하여 취침운전을 간편하게 선택할 수 있어 야간에 냉각실 내의 온도가 과도하게 상승하는 것을 억제시킬 수 있을 뿐만 아니라 정숙운전을 실시할 수 있는 냉장고와 그 온도제어방법이 제공된다.As described above, according to the present invention, the user can easily select the sleep operation by using the sleep operation selection button, so that the temperature in the cooling chamber is not excessively increased at night, and the quiet operation can be performed. A refrigerator and its temperature control method are provided.
