제3도는 본 발명의 급속냉동 제어방법을 보인 제어흐름도.3 is a control flow chart showing a rapid freezing control method of the present invention.

본 발명은 설정온도 및 고내온도와 냉동시간의 중첩적 판단에 의하여 경제적인 급속냉동운전을 수행하도록 하는 냉장고의 급속냉동 제어방법에 관한 것이다.The present invention relates to a rapid freezing control method of a refrigerator to perform economical rapid freezing operation by overlapping a set temperature, a high internal temperature and a freezing time.

종래의 급속냉동 제어방법은 제1도에 도시된 바와 같이, 단계(1)에서 급냉스위치가 온되었는지를 판별하고, 급냉 스위치가 오프되었으면 단계(2)에서 설정온도에 맞게 압축기 및 팬모터를 구동시키는 기본 냉장고의 기능을 수행한다.In the conventional rapid freezing control method, as shown in FIG. 1, it is determined whether the quench switch is turned on in step (1), and if the quench switch is turned off, the compressor and the fan motor are driven according to the set temperature in step (2). It serves as a basic refrigerator.

급냉 스위치가 온되었으면 단계(3)에서 압축기를 구동시키고, 단계(4)에서 급냉타이머를 온시키며, 단계(5)에서 급냉 타이머에 세팅된 시간, 예를들어 2시간이 경과되었는지를 판별하여 급냉시간이 경과되었으면, 단계(6)에서 급냉타이머를 오프시킨 후 초기화하고, 급냉스위치를 오프시킨다.If the quench switch is turned on, the compressor is driven in step (3), the quench timer is turned on in step (4), and the time set in the quench timer in step (5) is determined, for example, whether 2 hours have elapsed. If the time has elapsed, the quench timer is turned off and initialized in step 6, and the quench switch is turned off.

그러나 이러한 종래의 방식은 압축기를 고내온도와 관계없이 일정 시간동안 운전시키므로 평상시의 설정온도가 약 또는 절전운전으로 높게 설정되어 있을 경우 고내온도가 급속냉동시의 온도로 충분히 강하되지 않았어도 급속냉동이 끝나게 되어 급속냉동기능을 제대로 수행하지 못하게 되는 문제점이 있었다.However, since the conventional method operates the compressor for a certain time regardless of the internal temperature of the compressor, if the usual set temperature is set to high or low power saving operation, the rapid freezing ends even if the internal temperature is not sufficiently reduced to the temperature of the rapid freezing. There was a problem that can not properly perform the rapid freezing function.

따라서 본 말명의 목적은 설정온도에 따라 급속냉동 시간을 다르게 설정하여 고내온도가 충분히 급강하되도록 냉장고의 급속냉동제어 방법을 제공하는데 있다.Therefore, the purpose of the present invention is to provide a rapid freezing control method of the refrigerator so that the internal temperature drops sufficiently by setting the rapid freezing time differently according to the set temperature.

본 발명의 다른 목적은 고내온도를 감지하여 일정온도 이하로 되면 급속냉동과 무관하게 일정시간을 냉각시켜 불필요한 급속냉동 운전을 방지하도록 하는 냉장고의 급속냉동 제어방법을 제공하는데 있다.Another object of the present invention is to provide a rapid freezing control method of a refrigerator for detecting a high temperature in a temperature below a predetermined temperature to prevent unnecessary rapid freezing operation by cooling a predetermined time irrespective of rapid freezing.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명이 적용되는 냉장고의 내부블럭 구성도로서 이에 도시된 바와같이, 고내온도제어에 관한 전체동작을 제어하는 마이콤(10)과, 전원회로, 리세트회로, 발진회로등으로 이루어진 마이콤 주변회로(20)와, 급냉스위치, 온도조절기등으로 구성되어 마이콤(10)에 각종 동작 명령이나 설정온도 등을 입력시키는 기능선택부(30)와, 냉동실 및 냉장실의 온도를 각각 감지하는 온도감지부(40)와, 도어의 개폐상태나 이상 상태등을 감지하는 상태감지부(50)와, 마이콤(10)의 제어에 따라 압축기, 팬모터, 제상히터 등을 구동시키는 부하구동부(60)와, 마이콤(10)의 제어에 따라 현재의 동작상태나 온도등을 표시하는 표시부(70)로 구성되어 있다.2 is a block diagram of an internal block of a refrigerator to which the present invention is applied. As shown in FIG. 2, a microcomputer 10 including a microcomputer 10 for controlling the overall operation of high temperature control and a power supply circuit, a reset circuit, an oscillation circuit, and the like. Peripheral circuit 20, a quench switch, a temperature controller, etc., and a function selection unit 30 for inputting various operation commands or set temperatures to the microcomputer 10, and temperature sensing for sensing the temperature of the freezer compartment and the refrigerating compartment, respectively. The unit 40, the state detection unit 50 for detecting the open or closed state of the door, and the like, the load driving unit 60 for driving the compressor, fan motor, defrost heater and the like under the control of the microcomputer 10 and And a display unit 70 for displaying the current operating state, temperature, and the like under the control of the microcomputer 10.

제3도는 본 발명의 급속냉동 제어방법을 보인 제어흐름도이다. 먼저, 마이콤(10)은 단계(101)에서 급냉스위치가 온되었는지를 판별하고, 급냉스위치가 오프되었으면 단계(102)에서 설정된 온도에 맞게 압축기와 팬모터의 운전을 제어하는 기본냉장고의 기능을 수행한다.3 is a control flowchart showing the rapid freezing control method of the present invention. First, the microcomputer 10 determines whether the quench switch is turned on in step 101, and if the quench switch is turned off, performs the function of the basic refrigerator to control the operation of the compressor and the fan motor according to the temperature set in step 102. do.

급냉스위치가 온되었으면, 단계(103)에서 온도조절기의 설정온도에 맞는 급냉최대 허용시간을 설정하였는지를 판별하는데, 그 이유는 본 흐름도가 연속적인 폐순로로된 프로그램의 일부분이기 때문에 급속냉동기능의 수행시에 타이머 동작중의 초기화설정을 피하기 위한 것이다.If the quench switch is turned on, it is determined whether the quench maximum allowable time corresponding to the set temperature of the thermostat is set in step 103, since the flowchart is part of a program in a continuous closed order to perform the rapid freezing function. This is to avoid the initialization setting during timer operation.

급냉시간이 설정되지 않았으면, 단계(105)에서 온도조절기의 위치가 강위치 인지를 판별하고, 강위치이면 단계(106)에서 급냉타이머를 기본시간, 예를들어 2시간으로 세팅시킨다.If the quench time is not set, it is determined in step 105 whether the position of the thermostat is in the strong position, and if it is the strong position, in step 106 the quench timer is set to a base time, for example 2 hours.

강위치가 아닐 경우에는 단계(107)에서 온도조절기의 위치가 중위치인지를 판별하고, 중위치이면 단계(108)에서 급냉타이머를 기본시간에 일정시간을 더한 시간(2시간+ta)으로 세팅시키며, 중위치가 아닐 경우에는 단계(109)에서 약위치인지를 판별하여, 약위치이면 단계(110)에서 급냉타이머를 더 긴 시간(2시간+tb)으로 세팅시키고, 약위치가 아닐 경우에는 절전상태로 판단하여 단계(111)에서 급냉타이머를 약운전시보다 더 긴 시간(2시간+tc)으로 세팅시킨다.If it is not the strong position, it is determined whether the position of the temperature controller is in the middle position in step 107, and if it is the middle position, the quenching timer is set to the basic time plus a predetermined time (2 hours + ta) in step 108. If it is not the middle position, it is determined whether it is the weak position in step 109, and if it is the weak position, the quench timer is set to a longer time (2 hours + tb) in step 110, and when it is not the weak position, power saving is performed. Judging by the state, in step 111, the quench timer is set to a longer time (2 hours + tc) than during the weak operation.

이와같이 하여 온도조절기의 위치에 맞게 최적의 급속냉동시간이 설정되었으면, 단계(104)에서 시간설정 완료표시를 한 다음 다음번에 상기 과정이 반복되더라도 다시 시간세팅을 하지않고 바로 단계(112)를 수행하여 압축기와 팬모터를 구동시킴으로서 고내온도를 급강하시킨다.In this way, if the optimum rapid freezing time is set according to the position of the temperature controller, the time setting completion indication is displayed in step 104 and the step 112 is performed immediately without time setting even if the process is repeated next time. By driving the compressor and fan motor, the internal temperature of the high air is dropped.

다음에, 단계(113)에서 고내온도가 급속냉동을 위한 최소만족온도, 예를들어 -25℃ 이하인지를 판별하고, 급냉초기에 고내온도가 만족온도 이상일 경우에는 단계(114)에서 시간이 설정된 급냉타이머를 온시켜, 단계(115)에서 급냉시간이 경과되었는지를 계속적으로 판별한다.Next, in step 113, it is determined whether the high temperature inside is the minimum satisfaction temperature for rapid freezing, for example, -25 ° C. or less, and when the high temperature inside the quench is at a temperature higher than the satisfying temperature, the time is set in step 114. The quench timer is turned on to continuously determine whether the quench time has elapsed in step 115.

급속냉동중에 고내온도가 만족온도 이하로 되면 단계(116)에서 급속 냉동과 관계없는 평형타이머를 온시켜, 단계(117)에서 평형타이머에 세팅된 시간이 경과하였는지를 판단한다.When the internal temperature of the freezing temperature is below the satisfactory temperature during the rapid freezing, the balance timer is turned on in step 116 to determine whether the time set in the balance timer has elapsed in step 117.

이러한 상태로 운전하여 급냉타이머나 평형타이머에 의해 세팅된 시간이 경과되면, 단계(118)에서 급냉스위치를 오프시켜 다시 급속 냉동기능을 선택해줄 수 있게하고, 시간설정표시, 급냉타이머, 평형타이머를 모두 초기화하며, 급냉표시를 지워 사용자가 기능수행 유무를 인지할 수 있도록 한다.After operating in this state and the time set by the quenching timer or the equilibrium timer has elapsed, the quenching switch is turned off in step 118 so that the quick freezing function can be selected again, and the time setting display, the quenching timer and the equilibrium timer are changed. All are initialized and the quenching indication is cleared so that the user can recognize the function.

이상에서와 같이 본 발명은 온도조절기의 위치에 따라 급냉시간을 다르게 설정하므로 최적급냉 온도에 도달되는 시간 오차를 줄일 수 있고, 급속냉동중에 고내온도를감지하여 1차로 강하면 상태이면 일정시간을 냉각시켜 불필요한 급냉을 방지하므로 경제적인 효과가 있다.As described above, the present invention sets the quenching time differently according to the position of the temperature controller, thereby reducing the time error of reaching the optimum quenching temperature, and detecting the internal temperature during rapid freezing to cool down a predetermined time if the state is strong first. It is economical because it prevents unnecessary quenching.
