본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 냉장고의 운전을 제어하여 냉각효율을 향상시킴과 동시에 제빙량이 최대가 되도록 제어하기 위한 냉장고의 운전제어방법에 관한 것이다. The present invention relates to a refrigerator, and more particularly, to an operation control method of a refrigerator for controlling the operation of the refrigerator to improve cooling efficiency and to control the ice making amount to be maximum.                         

이하 종래 기술에 따른 냉장고의 운전제어방법에 대해 살펴보면 다음과 같다.Looking at the operation control method of the refrigerator according to the prior art as follows.

냉장고에서 냉매는 압축기, 응축기 및 모세관을 거쳐 증발기에 도달하여, 상기 증발기에서 증발된다. 이때 증발작용에 따른 기화열의 흡수에 의하여 증발기 부근의 열이 흡수되고, 이러한 과정에 생성된 냉기가 냉동실 및 냉장실로 순환되어 냉장고 내를 냉각한다.In the refrigerator, the refrigerant reaches the evaporator via a compressor, a condenser and a capillary tube and evaporates in the evaporator. At this time, the heat in the vicinity of the evaporator is absorbed by the absorption of the vaporization heat due to the evaporation action, the cold air generated in this process is circulated to the freezer compartment and the refrigerating compartment to cool the inside of the refrigerator.

상기 증발기에서 열을 빼앗긴 차가운 냉기의 일부는 냉동실로 순환하고, 나머지 일부는 냉장실을 순환하여 고내를 냉각시킨다. 한편, 냉동실 및 냉장실을 순환하는 동안에 더워진 냉기는 다시 증발기를 거침으로서 열을 빼앗기는 열교환작업을 반복하게 된다.Some of the cold air deprived of heat from the evaporator is circulated to the freezer compartment, and the other part is circulated in the refrigerator compartment to cool the inside of the refrigerator. On the other hand, the hot air during the circulation of the freezer compartment and the refrigerating compartment is repeated through the evaporator heat exchange operation to take heat away.

상기와 같이 열교환작업을 수행하여 고내에 냉기가 공급되도록 제어하는데 있어서, 고내에 냉기를 집중적으로 공급되도록 특급냉동기능을 선택한다. 상기 특급냉동기능 선택에 따라, 고내에 공급되는 냉기의 양을 증가시키기 위해서, 다음과 같은 열교환작업을 수행된다. 즉, 냉매를 압축하는 압축기의 구동이 고속으로 이루어지고, 이로 인해서 압축되는 냉매의 양이 증가하여, 결국 열교환을 수행하는 냉기의 양이 다량으로 토출된다.In performing the heat exchange operation as described above to control the supply of cold air in the refrigerator, the express refrigeration function is selected to concentrate the supply of cold air in the refrigerator. According to the above-mentioned special refrigeration function selection, in order to increase the amount of cold air supplied into the refrigerator, the following heat exchange operation is performed. That is, the driving of the compressor for compressing the refrigerant is made at a high speed, thereby increasing the amount of the refrigerant to be compressed, so that the amount of cold air for performing heat exchange is discharged in large quantities.

한편, 냉각된 냉기가 고내에 토출되기 위해서, 팬이 구동하게 된다. 이때 특급냉동의 경우는 고속으로 구동함으로서, 보다 고내에 냉각된 냉기가 신속하게 공급될 수 있도록 한다.On the other hand, the fan is driven in order to discharge the cooled cold air into the refrigerator. In this case, the express refrigeration is driven at a high speed so that cool air cooled in the refrigerator can be supplied more quickly.

이하 냉장고의 특급냉동시 운전상태에 대해서 좀 더 상세하세 살펴보면 다음 과 같다.Hereinafter, the operation state of the express freezing of the refrigerator will be described in more detail as follows.

도 1은 종래 기술에 따른 냉장고의 운전상태를 나타내는 상태도이다.1 is a state diagram showing an operating state of a refrigerator according to the prior art.

냉장고의 운전상태가 표준운전상태에서 특급냉동 운전상태에 돌입하면 도시된 바와 같이 냉동제어온도의 상태가 변화된다. 즉 도면에 도시된 바와 같이 냉동제어온도가 높은 '적' 상태에서, 압축기가 고속으로 연속구동하여 압축된 냉매가 열교환을 수행하고, 냉각된 증발기를 통과한 냉각된 냉기가 고내에 공급되도록 팬이 고속으로 구동한다.When the operation state of the refrigerator enters the express freezing operation state from the standard operation state, the state of the refrigeration control temperature is changed as shown. That is, as shown in the drawing, in a 'red' state where the refrigeration control temperature is high, the compressor is continuously driven at high speed so that the compressed refrigerant performs heat exchange, and the cooled cold air passing through the cooled evaporator is supplied into the refrigerator. Drive at high speed.

상기와 같이 압축기와 팬의 구동을 고속으로 운전하는 상태를 3시간동안 연속적으로 이루어지도록 구동제어됨에 따라, 냉동제어온도가 하강하게 된다. 이와 같이 고내의 온도가 급격하게 하강함에 따라서, 평상시 표준온도조건에서보다 빨리 고내를 냉각시킬 수 있었다. 상기와 같은 특급운전기능을 3시간 연속으로 구동하고 난 뒤, 냉동고 내의 운전은 특급운전기능 전의 운전상태로 전환된다.As described above, the driving control is performed to continuously operate the compressor and the fan at a high speed for three hours, thereby lowering the refrigeration control temperature. Thus, as the temperature in the refrigerator drastically decreased, the interior of the refrigerator could be cooled faster than the normal temperature condition. After driving the express operation function as described above continuously for 3 hours, the operation in the freezer is switched to the operation state before the express operation function.

이와 같이 종래의 특급냉동모드는 단지 일정시간 동안 압축기와 팬을 연속 그리고 고속으로 운전하므로서, 단순히 고내를 빨리 냉각시키는 기능만을 수행하고 있다.As described above, the conventional express freezing mode merely operates the compressor and the fan at a constant and high speed for a predetermined time, and simply performs a function of cooling the inside of the refrigerator quickly.

따라서 본 발명의 목적은, 압축기 및 팬의 고속운전과 더불어 냉동실만 냉기공급이 이루어지도록 제어하여 제빙량이 최대가 되도록 제어하는 냉장고의 운전제어방법을 제공함에 있다.Accordingly, it is an object of the present invention to provide a refrigerator operation control method of controlling a compressor to provide a maximum amount of ice by controlling only a freezer to supply cold air together with high-speed operation of a compressor and a fan.

상기 목적을 달성하기 위한 본 발명에 따른 냉장고의 운전제어방법은, 압축기 및 팬을 구동하여 열교환작업을 수행하여, 냉동실과 냉장실로 냉기를 공급하는 냉장고에 있어서, 특급냉동 제어신호를 입력하는 입력단계와; 상기 입력단계에 따라, 특급냉동제어신호가 입력되면, 압축기 및 팬이 연속으로 소정시간동안 고속회전시켜 고내온도가 단시간에 최저온도에 도달되도록 제어하는 제 1 제어단계와; 상기 제 1 제어단계가 소정시간 경과하면, 냉동실만 저온으로 제어하는 제 2 제어단계를 포함하여 구성된다.The operation control method of the refrigerator according to the present invention for achieving the above object, in the refrigerator for supplying cold air to the freezer compartment and the refrigerating compartment by performing a heat exchange operation by driving the compressor and the fan, an input step of inputting the express refrigeration control signal Wow; According to the input step, when the express refrigeration control signal is input, the first control step of controlling the compressor so that the high speed of the internal temperature reaches the minimum temperature in a short time by rotating the compressor for a predetermined time at a high speed; And a second control step of controlling only the freezing compartment at a low temperature when the first control step has elapsed for a predetermined time.

그리고 상기 목적을 달성하기 위한 본 발명에 따른 냉장고의 운전제어방법에서 상기 제 2 제어단계는, 압축기 및 팬이 일반운전으로 일정시간까지 구동하는 것을 특징으로 한다.In the operation control method of the refrigerator according to the present invention for achieving the above object, the second control step is characterized in that the compressor and the fan is driven to a predetermined time in the normal operation.

이하 본 발명에 따른 냉장고의 운전제어방법에 대해 좀 더 상세하게 살펴보면 다음과 같다.Hereinafter, the operation control method of the refrigerator according to the present invention will be described in more detail.

도 2는 본 발명에 따른 냉장고의 운전제어를 위한 제어구성도이다.2 is a control block diagram for operation control of the refrigerator according to the present invention.

제품에 전원을 공급하는 전원공급부(100)와, 동작제어신호를 입력하는 신호입력부(110)와, 사용자에게 동작기능을 표시하는 디스플레이부(120)와, 냉매를 압축하는 압축기구동부(160)와, 고내에 냉기가 공급되도록 구동하는 팬구동부(150)와, 고내의 온도를 감지하는 온도감지센서(140)와, 제품의 구동을 제어하는 마이크로컨트롤러(130)를 포함하여 구성된다.A power supply unit 100 for supplying power to the product, a signal input unit 110 for inputting an operation control signal, a display unit 120 for displaying an operation function to a user, a compressor driver 160 for compressing a refrigerant, In addition, the fan driving unit 150 to drive the cold air is supplied to the interior, the temperature sensor 140 for sensing the temperature in the interior, and comprises a microcontroller 130 for controlling the drive of the product.

상기 압축기구동부(160)를 포함한 응축기, 증발기의 구성을 통해서 열교환사이클을 구성하고, 압축된 냉매를 순환하여 냉기를 생성하는 일련의 과정을 반복한 다.The heat exchange cycle is configured through a condenser and an evaporator including the compressor driver 160, and a series of processes for generating cold air by circulating the compressed refrigerant are repeated.

상기 온도감지센서(140)는 고내에 구성되고, 본 발명에서는 냉동실에 구성하여 냉동실의 온도를 감지하는 기능을 수행한다. 상기 온도감지센서(140)는 특급냉동기능을 선택하여 운전을 수행함에 따라 고내에 변화되는 냉동제어온도를 감지하는 역할을 수행한다. 그리고 고내의 냉동제어온도가 소정온도에 도달하게 되면, 특급냉동기능이 수행되었다고 판단하여, 일정온도가 유지되도록 온도값을 마이크로컨트롤러(130)에 전달한다.The temperature sensor 140 is configured in the interior, in the present invention is configured in the freezer to perform the function of detecting the temperature of the freezer. The temperature sensor 140 performs a role of sensing the refrigeration control temperature changes in the refrigerator as the operation of selecting the express refrigeration function. When the refrigeration control temperature in the refrigerator reaches a predetermined temperature, it is determined that the express freezing function is performed, and the temperature value is transmitted to the microcontroller 130 to maintain a constant temperature.

상기 마이크로컨트롤러(130)에는 특급냉동에 따른 압축기 및 팬의 회전이 고속으로 구동되도록 제어하기 위해서, 압축기구동부(160)와 팬구동부(150)로 제어신호를 출력한다. 그리고 상기 마이크로컨트롤러(130)는 특급냉동기능이 제 1 일정시간 동안 이루어지도록 구동제어한다. 이때 압축기 및 팬이 제 2 일정시간 동안 고속으로 구동한 후, 제 1 일정시간 중 제 2 일정시간을 뺀 나머지 제 3 일정시간 동안 냉동실만 고내 냉동제어온도 조건을 '강'으로 제어하게 된다.The microcontroller 130 outputs control signals to the compressor driver 160 and the fan driver 150 to control the rotation of the compressor and the fan according to the express refrigeration at high speed. In addition, the microcontroller 130 controls to drive the express refrigeration function for a first predetermined time. At this time, after the compressor and the fan are driven at a high speed for a second predetermined time, the freezer control temperature condition in the freezer only is controlled to be 'strong' for the third predetermined time after subtracting the second predetermined time.

도 3은 본 발명에 따른 냉장고의 운전상태를 나타내는 상태도이다.3 is a state diagram showing an operating state of the refrigerator according to the present invention.

사용자가 설정한 운전상태로 냉동운전을 수행하는 냉장고에 있어서, 특급운전을 수행하기 위해서 신호입력부(110)를 통해서 특급냉동기능을 선택한다. 이에 따라 사용자가 입력한 특급냉동신호는 마이크로컨트롤러(130)에 전달되고, 상기 마이크로컨트롤러(130)는 특급냉동기능을 수행하도록 압축기구동부(160)와 팬구동부(150)의 고속 그리고 연속구동을 제어한다.In the refrigerator that performs the freezing operation in the operation state set by the user, the express freezing function is selected through the signal input unit 110 to perform the express operation. Accordingly, the express refrigeration signal input by the user is transmitted to the microcontroller 130, and the microcontroller 130 controls the high speed and continuous drive of the compressor driver 160 and the fan driver 150 to perform the express refrigeration function. do.

이에 따라 압축기구동부(160)를 통해서 냉매가 압축되고, 압축된 냉매가 응 축기, 팽창밸브, 증발기를 거쳐 열교환작업을 수행한다. 그리고 팬에 의해서 공기가 순환되어 고내에 냉기가 공급되게 된다. 이에 따라 상기와 같이 구동제어되어, 사용자가 입력한 특급냉동기능을 시작하면 고내에 냉각된 냉기가 고속으로 많이 공급됨으로서 고내의 온도가 하강한다.Accordingly, the refrigerant is compressed through the compressor driver 160, and the compressed refrigerant performs a heat exchange operation through a condenser, an expansion valve, and an evaporator. The air is circulated by the fan to supply cold air to the inside of the refrigerator. Accordingly, when the drive is controlled as described above and the user enters the express freezing function, a lot of cold air cooled in the refrigerator is supplied at a high speed, thereby lowering the temperature in the refrigerator.

그리고 고내에 구비된 온도감지센서(140)를 통해서 감지되는 고내온도가 특급냉동에 해당되는 최저온도에 도달하기까지 연속적으로 팬구동부(150)와 압축기구동부(160)가 구동되어 열교환작업을 수행하고, 냉각된 냉기가 냉동고 내에 공급되도록 한다. Then, the fan driver 150 and the compressor driver 160 are continuously driven until the internal temperature detected by the temperature sensor 140 provided in the refrigerator reaches the minimum temperature corresponding to the express freezing to perform heat exchange. Allow the chilled chilled air to feed into the freezer.

그 결과 상기 냉기가 냉동고 내에 공급됨에 따라, 냉동고내의 온도가 하강하게 된다. 그리고 상기와 같이 특급냉동기능에 따른 구동시간이 제 2 일정시간(본 발명에서는 3시간)에 도달하게 되면, 마이크로컨트롤러(130)는 종래 운전시보다 좀 더 고내 냉동제어온도가 높은 '강' 으로 냉동고내의 온도가 유지되도록 구동제어한다.As a result, as the cold air is supplied into the freezer, the temperature in the freezer drops. When the driving time according to the express refrigeration function reaches the second predetermined time (3 hours in the present invention) as described above, the microcontroller 130 is 'high', which has a higher internal refrigeration control temperature than the conventional operation. Drive control to maintain the temperature in the freezer.

즉, 제 2 일정시간(본 발명에서는 3시간)동안 연속으로 압축기구동부(160)를 구동제어하여 열교환작업을 수행하고, 제 2 일정시간이 경과되면 압축기구동부(160)를 일반운전으로 구동제어한다. 이때 냉동고 내의 온도가 '강'운전에 따른 기준고내온도를 유지하도록 구동된다.That is, the compressor driving unit 160 is continuously driven for a second predetermined time (3 hours in the present invention) to perform heat exchange operation, and when the second predetermined time elapses, the compressor driving unit 160 is driven and controlled by the general operation. . At this time, the temperature in the freezer is driven to maintain the reference temperature inside the 'strong' operation.

상기와 같이 압축기구동부(160)가 일반운전을 수행하여, 고내온도가 '강'운전에 따른 기준고내온도를 유지하도록, 제 1 일정시간에서 제 2 일정시간(본 발명에서는 3시간)을 뺀 나머지 제 3 일정시간 동안 '강'운전을 수행한다. As described above, the compressor driving unit 160 performs the general operation, so that the internal temperature is maintained by the reference high temperature according to the 'strong' operation, minus the second predetermined time (3 hours in the present invention). Carry out 'strong' operation for the third predetermined time.                     

이와 같이 특급운전이 수행됨에 따라, 단시간 내에 냉동고 내의 온도가 하강하고, 하강된 온도를 장시간 유지하는 것이 가능해진다. 또한, 냉동고 내에 있는 자동제빙기의 얼음이 단시간 내에 냉각될 수 있다. 이에 따라 냉각된 얼음이 이빙되어 급수되는 과정이 반복적으로 진행됨으로서, 결과적으로 얼음의 제빙량이 증가하는 효과도 가져온다.As the express operation is performed in this way, the temperature in the freezer drops within a short time, and it is possible to maintain the lowered temperature for a long time. In addition, the ice of the automatic ice maker in the freezer can be cooled in a short time. As a result, the process of repeatedly cooling the iced ice and watering the water brings about an effect of increasing the amount of ice making.

상기와 같이 본 발명에서는 제 1 일정시간 동안 압축기구동부(160)와 팬구동부(150)를 제어하여 특급냉동을 수행한 후, 특급냉동운전 전의 상태로 되돌아가도록 운전기능을 전환한다. 이에 따라, 고내의 온도가 특급냉동기능을 선택하기 이전의 온도로 도달하도록 냉동고 내에 공급되는 냉기량을 제어하면서, 고내온도를 제어하게 된다. As described above, in the present invention, after performing the express refrigeration by controlling the compressor driver 160 and the fan driver 150 for the first predetermined time, the operation function is switched to return to the state before the express refrigeration operation. Accordingly, the temperature in the refrigerator is controlled while controlling the amount of cold air supplied into the freezer so that the temperature in the refrigerator reaches a temperature before selecting the express freezing function.

도 4는 본 발명에 따른 냉장고의 운전에 따른 제빙량의 변화를 나타내는 상태도이다.4 is a state diagram showing a change in the amount of ice making according to the operation of the refrigerator according to the present invention.

도 4는 도시되고 있는 바와 같이 특급냉동기능과 일반냉동기능에 따른 제빙량의 상태변화를 도시하고 있다. 즉, 특급냉동기능과 일반냉동기능에서 기준운전온도에 따른 제빙량은 다음과 같이 나타나고 있다.4 shows a state change of the ice making amount according to the express freezing function and the general freezing function as shown. That is, the ice making amount according to the reference operating temperature in the express freezing function and the general freezing function is shown as follows.

즉, 특급냉동기능인 경우, 기준고내온도가 '적' 상태보다 '강' 상태에서 제빙량이 더 많아진다. 또한 일반냉동기능인 경우에도, 기준고내온도가 '적' 상태보다 '강' 상태에서 제빙량이 더욱 많아진다.That is, in the case of the express refrigeration function, the amount of ice making in the 'strong' state is higher than that of the 'high' standard reference temperature. In addition, even in the case of the normal freezing function, the amount of ice making in the 'strong' state is higher than the reference high temperature inside the 'red' state.

그리고 기준고내온도가 '적'상태에서, 특급냉동기능과 일반냉동기능의 제빙량을 비교해보면, 특급냉동기능을 수행한 결과에서 제빙량이 더욱 많음을 알 수 있 다.When the reference high temperature is 'low', comparing the ice making capacity of the express freezing function and the general freezing function, the result of the express freezing function shows that the amount of ice making is higher.

이와 같이 본 발명에 따른 냉장고의 운전제어방법은, 냉동고 내의 온도를 단시간 내에 적정온도에 도달하도록 제어하기 위해서 특급냉동기능을 수행한다. 그리고 상기 특급냉동기능을 수행함으로 인해서, 동시에 제빙기능도 향상된다.As described above, the operation control method of the refrigerator according to the present invention performs an express freezing function to control the temperature in the freezer to reach a proper temperature within a short time. And by performing the express freezing function, the ice making function is also improved at the same time.

이상 살펴본 바와 같이 본 발명은, 냉장고의 특급운전기능에 따른 냉동고 내의 온도를 제어하여, 냉동기능 뿐 아니라 제빙기능도 향상시키는 것을 기본적인 기술적 사상으로 한다.As described above, the present invention is to control the temperature in the freezer according to the express operation function of the refrigerator to improve not only the freezing function but also the ice making function as a basic technical idea.
