If it is determined that time, the defrost temperature detecting means 20 detects the temperature of the evaporator 4, while the microcomputer 10 outputs a driving stop signal to the cooling fan drive means 30 and the compressor drive means 50. Then, the compressor 9 and the cooling fan 3 are stopped and the defrost heater 6 is driven from the defrost heater driving means 40 to start defrosting.
제상돌입 후 성애가 녹으면서 제상온도감지수단(20)의 부착부위온도가 일정온도로 상승되면 제상온도감지수단(20)은 이를 감지하여 마이컴(10)에 입력하고 마이컴(10)은 제상히터(6)를 오프제어함으로써 제상을 종료하며, 동시에 압축기(9)와 냉각팬(3)을 구동시켜 다시 냉각 작용을 시작한다.After defrosting and defrosting, the defrosting temperature detecting means 20 rises to a certain temperature and the defrosting temperature detecting means 20 detects this and inputs it to the microcomputer 10 and the microcomputer 10 defrost heater ( Defrost is terminated by turning off 6), and at the same time, the compressor 9 and the cooling fan 3 are driven to start the cooling operation again.
이때, 상술한 바와 같이 제어되는 제상동작시의 증발실(4a) 통상 온도는 평상시 -20℃의 온도를 유지하나 제상 직후에는 제상히터(6)의 발열로 상승하여 8 ∼ 10℃의 온도분포를 갖는다.At this time, the normal temperature of the evaporation chamber 4a during the defrosting operation controlled as described above is normally maintained at a temperature of −20 ° C., but immediately after defrosting, the temperature rises to 8 to 10 ° C. due to the heating of the defrost heater 6.

따라서, 종래의 냉장고는 제상 직후 압축기 및 냉각팬이 동시에 동작하여 가열된 증발실의 더운 공기를 고내로 유출시킴으로서 냉기손실을 초래하는 문제점이 있었다.Therefore, the conventional refrigerator has a problem of causing a loss of cold air by simultaneously operating a compressor and a cooling fan immediately after defrosting to let hot air of the heated evaporation chamber out into the refrigerator.

In the case of turning off the compressor 9 and the cooling fan 3 and turning on the defrost heater 6, 104, 105 and 106, and then determining whether defrost has been completed 107. When the defrosting is completed, the compressor 9 is turned on again to perform a refrigeration cycle (108), and during the refrigeration cycle, it is determined whether the temperature of the evaporator (4) has dropped to an appropriate temperature. Operating (109) (110).
상기와 같은 구성으로 된 본 발명을 도 1 내지 도 3을 참조하여 상세히 설명하면 다음과 같다.The present invention having the above configuration will be described in detail with reference to FIGS. 1 to 3 as follows.
먼저 압축기(9)가 온되는 단계(101)를 통하여 냉동사이클이 수행되면 냉매가 증발기를 지나며 증발기 주위의 열을 빼앗아 증발실의 공기가 냉각된다.First, when the refrigerating cycle is performed through the step 101 in which the compressor 9 is turned on, the refrigerant passes through the evaporator and takes heat around the evaporator to cool the air in the evaporation chamber.
동시에 냉각팬이 온되어 상기 증발실의 냉각된 공기를 냉동실 및 냉장실로 공급함으로서, 냉동실(1) 및 냉장실(2)이 적정온도로 냉각되어 보관된 식품등이 장시간 동안 신선도를 유지하게 된다.At the same time, the cooling fan is turned on to supply the cooled air of the evaporation chamber to the freezing compartment and the refrigerating compartment, whereby the freezer compartment 1 and the refrigerating compartment 2 are cooled to an appropriate temperature to maintain freshness for a long time.
이후, 회수관(5)으로 상기 냉기가 회수되었다가 다시 증발실(4a)에서 재차 냉각되어 냉동실(1) 및 냉장실(2)로 공급되나, 상기 과정이 반복 수행되는 동안 상기 증발기(4)의 표면에는 외부 온도차에 의해 성애가 발생하여 냉기의 전달을 차단함으로 냉각효율이 크게 떨어지게 된다.Thereafter, the cold air is recovered to the recovery pipe 5 and then cooled again in the evaporation chamber 4a and supplied to the freezing chamber 1 and the refrigerating chamber 2, but the process of the evaporator 4 is repeatedly performed. Defrost occurs on the surface due to the external temperature difference, the cooling efficiency is greatly reduced by blocking the transfer of cold air.
따라서, 제상히터(6)를 동작시켜 발생되는 열로서 상기 증발기(4)의 성애를 제거하게 되는데, 이때 마이컴(10)에 의해 압축기운전 누적시간, 압축기 운전율, 도어오픈 누적시간, 외기온도 등의 정보를 비교 분석한 후 제상돌입시간이라고 판단 되면 냉각팬구동수단(30) 및 압축기구동수단(50)에 구동정지신호를 출력하여 압축기(9) 및 냉각팬(3)을 정지시킴과 동시에 제상히터구동수단(40)으로부터 제상히터(6)를 구동시켜 제상을 시작하게 된다(103-106).Therefore, the defrost of the evaporator 4 is removed as the heat generated by operating the defrost heater 6, in which the microcomputer 10, the compressor operation cumulative time, compressor operation rate, door open accumulation time, outside air temperature, etc. After comparing and analyzing the information of the defrosting time, if it is determined that the defrost inrush time outputs the drive stop signal to the cooling fan drive means 30 and the compressor drive means 50 to stop the compressor (9) and the cooling fan (3) at the same time defrost The defrost heater 6 is driven from the heater driving means 40 to start defrosting (103-106).
소정시간 제상이 이루어진 후 제상이 완료되었는가를 판단하는 단계(107)에서 제상온도감지수단(20)의 부착부위온도가 일정온도로 상승되면 제상온도감지수단(20)은 이를 감지하여 마이컴(10)에 입력하고 상기 마이컴(10)은 제상히터구동수단(40)을 통하여 제상히터(6)를 오프제어함으로써 제상을 종료한다.After the defrosting has been performed for a predetermined time, if the defrosting temperature sensing unit 20 rises to a predetermined temperature in step 107, the defrosting temperature detecting means 20 detects the microcomputer 10. The microcomputer 10 terminates the defrost by off-controlling the defrost heater 6 through the defrost heater driving means 40.
이때, 상술한 바와 같이 제어되는 제상동작시 증발실(4a)의 통상 온도는 평상시 -20℃의 온도를 유지하나 제상 직후에는 제상히터(6)의 발열로 상승하여 8 ∼ 10℃의 온도분포를 갖는다.At this time, during the defrosting operation controlled as described above, the normal temperature of the evaporation chamber 4a normally maintains a temperature of -20 ° C, but immediately after defrosting, the temperature of the defrost heater 6 is raised to generate a temperature distribution of 8 to 10 ° C. Have
따라서, 본 발명은 제상 직후 압축기(9) 및 냉각팬(3)을 동시에 구동시키지 않고 압축기(9) 만을 소정시간 구동시켜 상기 냉동사이클을 수행시킨 후 증발실(4a)이 충분히 냉각되도록 한다(108).Therefore, in the present invention, the evaporation chamber 4a is sufficiently cooled after the compressor 9 is driven for a predetermined time without performing the compressor 9 and the cooling fan 3 at the same time immediately after defrosting. ).
이후 증발기(4)의 온도를 측정하여 설정된 기준온도까지 하강되었는가를 판단하고 설정온도에 도달하였을 경우 냉각팬(3)을 온 시켜 냉기를 냉동실(1) 및 냉장실(2)로 순환하게 한다(109)(110).Thereafter, the temperature of the evaporator 4 is measured to determine whether the temperature has dropped to the set reference temperature, and when the set temperature is reached, the cooling fan 3 is turned on to circulate the cold air into the freezing chamber 1 and the refrigerating chamber 2 (109). 110).
따라서 본 발명은 제상 직후 압축기 및 냉각팬이 동시에 동작하여 가열된 증발실의 공기를 고내로 유출시켜 발생되는 냉기손실을 제거하여 냉장고 효율을 상승시키는 효과가 있다.Therefore, the present invention has the effect of increasing the efficiency of the refrigerator by eliminating the loss of cold air generated by flowing the air of the heated evaporation chamber into the refrigerator immediately after the compressor and the cooling fan at the same time.
본 발명은 냉장고에 관한 것으로서, 더욱 상세하게는 제상 직후 압축기 및 냉각팬이 동시에 동작하여 가열된 증발실의 공기를 고내로 유출시킴으로 발생되는 냉기손실을 제거하여 냉장고 효율을 상승시킨 냉장고의 냉각팬제어방법을 제공함에 그 목적이 있다.The present invention relates to a refrigerator, and more particularly, to control a cooling fan of a refrigerator in which a compressor and a cooling fan are simultaneously operated immediately after defrosting, thereby removing cold air loss caused by flowing air from a heated evaporation chamber into a refrigerator.
