Abstract

PURPOSE: A control method of a refrigeration compartment is provided to prevent a refrigeration compartment from being run in a weak mode by automatically converting a temperature control button into a rapid mode when a user opens a refrigerator door frequently. CONSTITUTION: A temperature sensor of a refrigeration compartment detects indoor temperature of a refrigeration compartment when a user pushes a temperature control button. A refrigerator fan is driven according to a control signal of a microcomputer. The microcomputer saves opening frequency of a refrigerator door by deciding opening of the refrigerator. If the refrigerator door is opened five and more times per hour, the microcomputer decides driving of the refrigerator fan by comparing the refrigerator temperature with set temperature. A run mode of a refrigerator is automatically converted into a rapid mode, and the refrigerator fan is driven under drive conditions. The refrigerator is run normally after the rapid mode. Therefore, the refrigerator is prevented from running in a weak mode even though the user opens the refrigerator door frequently.

Description

냉장고의 냉장실 운전 제어방법How to control the operation of the refrigerator

본 발명은 냉장고 운전방법에 관한 것으로서, 특히 냉장고의 냉장실 도어의 오픈이 잦을 때의 냉장고의 냉장실 운전 제어방법에 관한 것이다.The present invention relates to a method for operating a refrigerator, and more particularly, to a method for controlling a refrigerator operation of a refrigerator when the refrigerator door is frequently opened.

일반적으로 냉장고는 음식물을 일정기간 동안 신선하게 유지시키는 용도로 사용되는 전자제품으로 첨부도면 도 1에 도시된 바와같이 본체(10)와, 본체(10) 내부에 양분되어 음식물을 냉동 보관하는 냉동실(11) 및 냉장 보관하는 냉장실(12)과, 본체(10)의 전면에 설치되어 냉동실(11)을 개폐시켜 주는 냉동실도어(13) 및 냉장실(12)을 개폐시켜 주는 냉장실도어(14)와, 상기 냉동실(11)과 냉장실(12)의 냉각에 필요한 냉기를 만들어 주는 냉동싸이클과, 냉동싸이클에서 만들어진 냉기를 냉동실(11) 및 냉장실(12)로 보내주는 냉기공급수단으로 크게 구성되어 있다.In general, a refrigerator is an electronic product used for keeping food fresh for a certain period of time. As shown in FIG. 1, the refrigerator is divided into a main body 10 and a freezer compartment for freezing and storing food in the main body 10. 11) and a refrigerating chamber 12 for refrigerating, a refrigerating chamber door 13 for opening and closing the freezer compartment 11 and a refrigerating chamber door 14 for opening and closing the freezer compartment 11 at the front of the main body 10, It is composed of a freezing cycle for making the cold air required for cooling the freezing chamber 11 and the refrigerating chamber 12, and a cold air supply means for sending the cold air made in the freezing cycle to the freezing chamber 11 and the refrigerating chamber 12.

상기와 같은 냉장고의 냉동싸이클은 도 2에 나타낸 바와같이 저온, 저압의 기체냉매를 고온, 고압의 기체냉매로 압축하는 압축기(15)와, 상기 고온, 고압의 기체냉매를 응축시켜 고온, 고압의 액체냉매로 변환시켜 주는 응축기(16)와, 상기 고온, 고압의 액체냉매를 저온, 저압의 액체냉매로 변환시켜 주는 모세관(17)과, 상기 저온, 저압의 액체냉매를 저온, 저압의 기체냉매로 증발시켜 주는 증발기(18)와, 상기 각 구성품을 일체화하면서 냉매의 이동통로 역할하는 연결파이프(19)로 구성되어 있다.As shown in FIG. 2, the refrigerating cycle of the refrigerator includes a compressor 15 for compressing a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant, and condensing the high-temperature, high-pressure gas refrigerant to a high-temperature, high-pressure pressure. A condenser 16 for converting a liquid refrigerant, a capillary tube 17 for converting the high temperature and high pressure liquid refrigerant into a low temperature and low pressure liquid refrigerant, and a low temperature and low pressure gas refrigerant for the low temperature and low pressure liquid refrigerant. And an evaporator 18 for evaporating the furnace, and a connecting pipe 19 serving as a moving passage of the refrigerant while integrating the respective components.

따라서, 냉동실(11)에 냉동용 음식물을 채우고 냉장실(12)에는 냉장용 음식물을 채운상태에서 전원을 공급시키면 콘트롤러의 제어신호를 받아 냉동싸이클을 구성하는 압축기(15)가 구동되어 저온, 저압의 기체냉매를 고온, 고압의 기체냉매로 압축시킨다.Therefore, when the refrigeration chamber 11 is filled with the food for freezing and the refrigeration chamber 12 is supplied with the refrigerated food in the state of filling the refrigerated food, the compressor 15 constituting the refrigeration cycle is driven under the control signal of the controller to operate at low temperature and low pressure. The gas refrigerant is compressed into a gas refrigerant of high temperature and high pressure.

이 압축된 고온, 고압의 기체냉매는 연결파이프(19)에 안내되어 응축기(16)를 통과하면서 고온, 고압의 액체냉매로 응축되며 이 응축된 고온, 고압의 액체냉매는 연결파이프(19)에 안내되어 모세관(17)를 통과하면서 온도와 압력이 급격히 떨어진 저온, 저압의 액체냉매로 변환된 다음 계속해서 연결파이프(19)에 안내되어 증발기(18)를 통과하면서 저온, 저압의 기체냉매로 변환되어 증발되는데, 이때 상기 증발기(18)의 증발작용에 의해 주위의 공기가 열교환되므로 냉기가 발생된다.The compressed high-temperature, high-pressure gas refrigerant is guided to the connecting pipe 19 and condensed into a high-temperature, high-pressure liquid refrigerant while passing through the condenser 16. The condensed high-temperature, high-pressure liquid refrigerant is transferred to the connecting pipe 19. Guided through the capillary tube 17, the temperature and pressure is rapidly converted into low-temperature, low-pressure liquid refrigerant and then guided to the connecting pipe 19 to pass through the evaporator 18 to convert to low-temperature, low-pressure gas refrigerant The evaporator 18 is then evaporated. At this time, the ambient air is heat-exchanged by the evaporation of the evaporator 18 so that cold air is generated.

이와같이 증발기(18)에서 발생된 냉기는 냉기공급수단에 의해 일부가 냉동실(11)로 공급되어 상기 냉동실(11)을 냉각시켜 주므로 냉동실(11)에 보관된 음식물이 냉동됨과 함께 일부가 냉장실(12)로 공급되어 상기 냉장실(12)을 냉각시켜 주므로 냉장실(12)에 보관된 음식물이 냉장된다.As such, the cold air generated in the evaporator 18 is partially supplied to the freezing chamber 11 by the cold air supply means to cool the freezing chamber 11, so that the food stored in the freezing chamber 11 is frozen and a portion of the cold chamber 12 is cooled. Since the refrigerator is cooled to the refrigerator compartment 12, the food stored in the refrigerator compartment 12 is refrigerated.
