Description

전자렌지의 온도제어방법Temperature control method of microwave oven

본 발명은 전자렌지의 온도제어방법에 관한 것으로, 상세하게는 전자렌지에서 조리를 할 때 온도감지부의 설정온도를 두 단계로 구분하여 조리 초기에는 정상 조리온도보다 낮게 설정된 예열온도에서 열원을 오프시키고, 그 이후에는 설정된 조리온도에서 열원을 온/오프시키는 전자렌지의 온도제어방법에 관한 것이다.The present invention relates to a temperature control method of a microwave oven, and in particular, when cooking in a microwave oven, by dividing the set temperature of the temperature sensing unit into two stages and at the initial stage of cooking, the heat source is turned off at a preheating temperature lower than the normal cooking temperature After that, the present invention relates to a temperature control method of a microwave oven which turns on / off a heat source at a set cooking temperature.

일반적으로 전자렌지는 열전도 및 열복사등을 이용한 종래의 외부 가열방식의 조리 기구와는 달리 마그네트론이라는 초고주파 발진관에 고압전기를 가하여 2450㎒의 초고주파를 발진시켜, 발진된 초고주파를 전자렌지 조리실 내부로 방사하여 음식물에 함유된 수분의 분자배열을 반복 변환시킴으로써 분자들간의 마찰열에 의하여 음식물을 조리하는 기구이다. 또한 전자렌지는 컨벡션히터등을 구비하여 히터의 열과 마그네트론에 의해서 조리를 하기도 한다.In general, microwave ovens, unlike conventional cookware of external heating method using heat conduction and heat radiation, apply high voltage electricity to an ultra-high frequency oscillator tube called magnetron to oscillate 2450MHz ultra-high frequency and radiate the oscillated ultra-high frequency into the microwave cooking chamber. It is a mechanism for cooking food by frictional heat between molecules by repeatedly converting the molecular arrangement of the moisture contained in the food. In addition, the microwave oven is equipped with a convection heater and the like to cook by the heat of the heater and the magnetron.

도 1은 종래의 전자렌지의 온도제어방법의 제어 흐름도이다.1 is a control flowchart of a temperature control method of a conventional microwave oven.

도 2는 종래의 전자렌지의 온도제어방법에 의한 조리실 온도의 그래프이다.2 is a graph of a cooking chamber temperature according to a temperature control method of a conventional microwave oven.

전자렌지의 컨벡션조리 동작을 살펴보면 다음과 같다.The convection cooking operation of the microwave is as follows.

사용자 조리하고자 하는 음식물을 조리실내에 넣고, 입력부를 통하여 컨벡션조리를 설정을 한다(S10). 이때 온도와 조리시간등도 같이 설정된다.The food to be cooked by the user is put in the cooking chamber and the convection cooking is set through the input unit (S10). At this time, the temperature and cooking time are also set.

설정을 한 후, 조리를 시작되면 제어부는 컨벡션히터를 동작시킨다(S20). 컨벡션히터가 동작되면 조리실이 가열되는데, 이때 제어부는 온도감지부를 통하여 조리실의 온도를 감지하고, 감지된 조리실의 온도가 설정된 온도에 도달하였는지를 판단한다(S30).After setting, when cooking is started, the control unit operates the convection heater (S20). When the convection heater is operated, the cooking chamber is heated. At this time, the controller detects the temperature of the cooking chamber through the temperature sensing unit and determines whether the detected temperature of the cooking chamber reaches the set temperature (S30).

만약 판단(S30)에서 감지된 조리실의 온도가 설정된 온도에 도달하지 못했다고 판단되면 제어부는 계속적으로 컨벡션히터를 동작시킨다. 하지만 판단()에서 감지된 조리실의 온도가 설정된 온도에 도달했다고 판단되면 제어부는 컨벡션히터를 오프시킨다(S40).If it is determined in the determination (S30) that the detected temperature of the cooking chamber does not reach the set temperature, the controller continuously operates the convection heater. However, if it is determined that the detected temperature of the cooking chamber reaches the set temperature in the determination (), the control unit turns off the convection heater (S40).

컨벡션히터가 오프되면 제어부는 타이머를 통하여 조리시간이 종료하여 조리가 완료되었는지를 판단한다(S50).When the convection heater is off, the controller determines whether cooking is completed by ending the cooking time through a timer (S50).

만약 판단(S50)에서 조리시간이 종료하지 않아서 조리가 완료되지 않았다고 판단되면 제어부는 일단 조리실의 온도가 설정된 온도에 도달했으므로 소정시간을 지연시킨다(S60). 그리고 나서 조리실의 온도가 낮아지면 제어부는 다시 컨벡션히터를 동작시킨다. 전술한 동작은 설정된 조리시간이 종료할 때까지 반복하여 이루어진다.If it is determined in the determination S50 that the cooking time is not finished because the cooking time is not finished, the control unit once delays the predetermined time since the temperature of the cooking chamber reaches the set temperature (S60). Then, when the temperature of the cooking chamber decreases, the control unit operates the convection heater again. The above operation is repeated until the set cooking time ends.

그런데 전술한 온도감지부는 온도를 감지하기 위해서 온도감지부의 표면에서 내부로 열이 전도되는 시간이 필요하다. 그래서 온도감지부가 조리실의 온도를 감지할 때, 초기에는 조리실의 온도가 설정온도에 도달했음에도 불구하고 온도감지부의 내부로 온도가 완전하게 전도되지 못했기 때문에, 온도감지부는 조리실의 온도를 실제온도보다 낮은 온도로 감지하게 된다. 그래서 컨벡션히터는 계속 구동되고 그에 따라서 조리실을 설정온도이상 과도하게 가열하게 되어 에너지가 낭비되고 조리시간이 오래 걸리는 문제점이 있었다.However, the above-described temperature sensing unit needs a time for conducting heat from the surface of the temperature sensing unit to the inside in order to sense the temperature. Therefore, when the temperature sensing unit detects the temperature of the cooking chamber, the temperature sensing unit lowers the temperature of the cooking chamber lower than the actual temperature because the temperature was not completely conducted into the temperature sensing unit at the beginning even though the temperature of the cooking chamber reached the set temperature. It is detected by temperature. Therefore, the convection heater is continuously driven and accordingly, the cooking chamber is heated excessively above the set temperature, which wastes energy and takes a long cooking time.

본 발명은 상기한 문제를 해결하기 위하여 안출된 것으로, 그 목적은 전자렌지에서 히터를 이용하여 조리를 할 때 설정온도를 두 단계로 구분하여 조리 초기에는 설정된 조리온도보다 낮게 설정된 예열온도에서 히터를 오프시키고 그 이후에는 설정된 조리온도에서 히터를 온/오프시킴으로서, 온도감지부의 온도전달시간에 의한 온도감지오차를 보정하여 조리시간을 단축시키며 에너지를 절감할 수 있는 전자렌지의 온도제어방법을 제공하고자 하는 것이다.The present invention has been made in order to solve the above problems, the object is to separate the set temperature when cooking using a heater in a microwave oven in two stages to heat the heater at a preheating temperature set lower than the set cooking temperature at the beginning of cooking By turning the heater on and off at a set cooking temperature thereafter, it is possible to provide a temperature control method of a microwave oven that can shorten the cooking time and save energy by correcting a temperature sensing error caused by the temperature transfer time of the temperature sensing unit. It is.

As shown in FIG. In addition, a fan motor driving unit 81 for driving the fan motor 82 is connected to the control unit 40.

본 발명에 따른 전자렌지의 온도제어방법을 살펴보면 다음과 같다.Looking at the temperature control method of the microwave oven according to the present invention.

사용자 조리하고자 하는 음식물을 조리실내에 넣고, 입력부(10)를 통하여 컨벡션조리를 설정을 한다(S110). 이때 조리 온도와 조리시간등도 같이 설정된다. 조리 온도가 설정되면 제어부(40)는 설정된 조리온도보다 낮은 온도로 예열온도를 설정한다(S120).The food to be cooked by the user is placed in the cooking chamber and the convection cooking is set through the input unit 10 (S110). At this time, the cooking temperature and the cooking time are also set. When the cooking temperature is set, the controller 40 sets the preheating temperature to a temperature lower than the set cooking temperature (S120).

이때 조리온도보다 낮은온도로 예열온도를 설정하는 이유는 다음과 같다. 온도감지부(30)는 온도를 감지하기 위해서 온도감지부(30)의 표면에서 내부로 열이 전도되는 시간이 필요하다. 그래서 그 시간지연만큼의 온도감지부(30)의 온도감지 오차를 보정하기 위하여 설정된 조리온도보다 낮은 온도로 예열온도를 설정함으로서, 조리 초기에 조리실의 온도가 설정된 조리온도에 이르렀을 때 온도감지부(30)는 조리실의 온도가 예열온도라고 감지한다. 즉, 온도감지부(30)는 조리온도보다 낮은 온도인 예열온도를 감지할 때, 조리실의 실제온도는 설정된 조리온도가 되는 것이다. 그래서 실제로 온도감지부(30)가 조리초기에 조리실의 온도를 감지할 때, 조리실의 온도가 설정된 조리온도에 이르기까지 온도를 감지하는 시간을 단축시킬 수 있다.The reason for setting the preheating temperature to a temperature lower than the cooking temperature is as follows. The temperature sensing unit 30 needs a time for conducting heat from the surface of the temperature sensing unit 30 to the inside in order to sense the temperature. Thus, by setting the preheating temperature to a temperature lower than the cooking temperature set to correct the temperature sensing error of the temperature sensing unit 30 as much as the time delay, when the temperature of the cooking chamber reaches the set cooking temperature at the beginning of cooking, the temperature sensing unit 30 senses that the cooking chamber temperature is a preheating temperature. That is, when the temperature detector 30 detects a preheating temperature that is lower than the cooking temperature, the actual temperature of the cooking chamber becomes the set cooking temperature. Therefore, when the temperature detector 30 senses the temperature of the cooking chamber at the beginning of cooking, the time for detecting the temperature until the temperature of the cooking chamber reaches the set cooking temperature can be shortened.

단계(S120)에서 설정이 끝나면, 제어부(40)는 조리를 하기 위하여 컨벡션히터구동부(61)를 제어하여 컨벡션히터(62)를 동작시킨다(S130). 컨벡션히터(62)가 동작되면 조리실이 가열되는데, 이때 제어부(40)는 온도감지부(30)를 통하여 조리실의 온도를 감지하고, 감지된 조리실의 온도가 설정된 예열온도에 도달하였는지를 판단한다(S140).After the setting is completed in step S120, the controller 40 controls the convection heater driving unit 61 to operate the convection heater 62 to cook (S130). When the convection heater 62 is operated, the cooking chamber is heated. At this time, the control unit 40 detects the temperature of the cooking chamber through the temperature sensing unit 30 and determines whether the detected cooking chamber temperature has reached the preset preheating temperature (S140). ).

만약 판단(S140)에서 감지된 조리실의 온도가 설정된 예열온도에 도달하지 못했다고 판단되면 제어부(40)는 계속적으로 컨벡션히터구동부(61) 컨벡션히터(62)를 동작시킨다(S130).If it is determined in operation S140 that the detected temperature of the cooking chamber does not reach the preset preheating temperature, the controller 40 continuously operates the convection heater driving unit 61 and the convection heater 62 (S130).

하지만 판단(S140)에서 감지된 조리실의 온도가 예열온도에 도달했다고 판단되면 제어부(40)는 컨벡션히터구동부(61)를 제어하여 컨벡션히터(62)를 오프시킨다(S150). 이때 온도감지부(30)는 충분히 가열이 되어 있지 않은 상태이기 때문에, 온도감지부(30)의 내부로 조리실의 열기가 전도되는 시간오차에 의하여 온도감지부(30)가 감지하는 예열온도는 조리온도보다 낮은 온도이지만 온도감지부(30)가 예열온도를 감지했을 때 조리실의 실제온도는 거의 조리온도가 된다.However, if it is determined in the determination (S140) that the detected temperature of the cooking chamber has reached the preheating temperature, the controller 40 controls the convection heater driving unit 61 to turn off the convection heater 62 (S150). At this time, since the temperature sensing unit 30 is not sufficiently heated, the preheating temperature detected by the temperature sensing unit 30 is cooked due to a time error in which heat of the cooking chamber is conducted inside the temperature sensing unit 30. Although the temperature is lower than the temperature, when the temperature detecting unit 30 senses the preheating temperature, the actual temperature of the cooking chamber is almost the cooking temperature.

그리고 나서 제어부(40)는 소정시간을 지연(S160)시킨 후, 컨벡션히터구동부(61)를 제어하여 컨벡션히터(62)를 동작시킨다(S170). 컨벡션히터(62)가 동작하면 소정시간지연에 의하여 온도가 낮아졌던 조리실의 온도가 상승한다. 이때 제어부(40)는 온도감지부(30)를 통하여 조리실의 온도를 감지하고, 그 감지된 조리실의 온도가 설정된 조리온도에 도달하였는지를 판단한다(S180). 이때에는 이미 예열에 의하여 온도감지부(30)가 충분히 가열되어 있는 상태이기 때문에 온도감지부(30)는 오차없이 조리실의 온도를 감지할 수 있다.Thereafter, the controller 40 delays the predetermined time (S160), and then controls the convection heater driver 61 to operate the convection heater 62 (S170). When the convection heater 62 is operated, the temperature of the cooking chamber where the temperature is lowered due to a predetermined time delay increases. At this time, the control unit 40 detects the temperature of the cooking chamber through the temperature sensing unit 30 and determines whether the detected temperature of the cooking chamber reaches a set cooking temperature (S180). At this time, since the temperature sensing unit 30 is sufficiently heated by preheating, the temperature sensing unit 30 may sense the temperature of the cooking chamber without error.

판단(S180)에서 감지된 조리실의 온도가 설정된 조리온도에 도달했다고 판단되면 제어부(40)는 컨벡션히터구동부(61)를 제어하여 컨벡션히터(62)를 오프시킨다(S190).If it is determined in operation S180 that the detected temperature of the cooking chamber reaches the set cooking temperature, the controller 40 controls the convection heater driving unit 61 to turn off the convection heater 62 (S190).

컨벡션히터(62)가 오프되면 제어부(40)는 타이머를 통하여 조리시간이 종료하여 조리가 완료되었는지를 판단한다(S200).When the convection heater 62 is off, the controller 40 determines whether cooking is completed by ending the cooking time through a timer (S200).

만약 판단(S200)에서 조리시간이 종료하지 않아서 조리가 완료되지 않았다고 판단되면 일단 조리실의 온도가 설정된 조리온도에 도달했으므로 제어부(40)는 컨벡션히터(62)가 오프된 상태에서 소정시간을 지연시킨다(S160).If it is determined in the determination S200 that the cooking is not completed because the cooking time is not finished, since the temperature of the cooking chamber reaches the set cooking temperature, the controller 40 delays the predetermined time in the state in which the convection heater 62 is turned off. (S160).

그리고 나서 소정시간이 지나서 조리실의 온도가 설정된 조리온도보다 낮아지면 제어부(40)는 다시 컨벡션히터구동부(61)를 제어하여 컨벡션히터(62)를 동작시킨다(S170).Then, when the temperature of the cooking chamber becomes lower than the set cooking temperature after a predetermined time, the control unit 40 again controls the convection heater driving unit 61 to operate the convection heater 62 (S170).

컨벡션히터(62)가 동작하면 낮아졌던 조리실의 온도가 상승한다. 이때 제어부(40)는 온도감지부(30)를 통하여 조리실의 온도를 감지하고, 그 감지된 조리실의 온도가 설정된 조리온도에 도달하였는지를 판단한다(S180).When the convection heater 62 operates, the temperature of the lower cooking chamber increases. At this time, the control unit 40 detects the temperature of the cooking chamber through the temperature sensing unit 30 and determines whether the detected temperature of the cooking chamber reaches a set cooking temperature (S180).

판단(S180)에서 감지된 조리실의 온도가 설정된 조리온도에 도달했다고 판단되면 제어부(40)는 컨벡션히터구동부(61)를 제어하여 컨벡션히터(62)를 오프시킨다(S190). 컨벡션히터(62)가 오프되면 제어부(40)는 타이머를 통하여 조리시간이 종료하여 조리가 완료되었는지를 판단한다(S200).If it is determined in operation S180 that the detected temperature of the cooking chamber reaches the set cooking temperature, the controller 40 controls the convection heater driving unit 61 to turn off the convection heater 62 (S190). When the convection heater 62 is off, the controller 40 determines whether cooking is completed by ending the cooking time through a timer (S200).

판단(S200)에서 조리시간이 종료했다고 판단되면 제어부(40)는 조리가 완료되었다고 판단하여 종료를 한다.If it is determined in the determination S200 that the cooking time has ended, the controller 40 determines that cooking is completed and ends.

도 5를 참조하면 다시 설명하면, 예열온도를 조리온도보다 낮은 온도로 설정함으로서, 조리개시 후 조리실의 온도가 설정된 조리온도가되어 조리구간에 도달하는 시간이 종래보다 짧아진다. 즉, 예열구간의 시간이 짧아진다. 그래서 실제로 온도감지부(30)가 조리초기에 조리실의 온도를 감지할 때, 조리실의 온도가 설정된 조리온도에 이르기까지 온도를 감지하는 시간을 단축시킬 수 있으므로 전체 조리시간을 줄일 수 있다. 그래서 그만큼 에너지를 절감할 수 있다.Referring to FIG. 5 again, by setting the preheating temperature to a temperature lower than the cooking temperature, the temperature of the cooking chamber becomes the set cooking temperature after the start of the cooking, and the time for reaching the cooking section is shorter than before. That is, the time for the preheating section is shortened. Therefore, when the temperature sensor 30 detects the temperature of the cooking chamber at the beginning of cooking, the time for sensing the temperature until the temperature of the cooking chamber reaches the set cooking temperature can be shortened, thereby reducing the overall cooking time. So you can save energy.

본 발명에 따른 전자렌지의 온도제어방법에 의하면, 조리를 할 때 조리실의 온도를 조리온도와 그 조리온도보다 낮은 온도인 예열온도로 구분하여, 조리 초기에는 온도감지부를 통하여 감지한 조리실의 온도가 예열온도일 때까지만 컨벡션히터등의 열원을 구동시켜 조리실을 가열하고, 그 이후에는 온도감지부를 통하여 감지한 조리실의 온도가 조리온도일 때까지 컨벡션히터등의 열원을 구동시켜 조리실을 가열함으로서, 조리 초기에 온도감지부가 조리실의 온도를 감지하여 열원이 오프되는 시간을 단축시킬 수 있어 조리 초기에 조리실이 과다하게 가열되는 것을 방지하고 실제 조리시간을 줄일 수 있으므로 에너지를 절감할 수 있다.According to the temperature control method of the microwave oven according to the present invention, when cooking, the temperature of the cooking chamber is divided into a cooking temperature and a preheating temperature which is lower than the cooking temperature. By heating the cooking chamber by driving a heat source such as a convection heater only until the preheating temperature, and then heating the cooking chamber by driving a heat source such as a convection heater until the temperature of the cooking chamber detected by the temperature sensing unit is the cooking temperature. Initially, the temperature sensing unit senses the temperature of the cooking chamber to shorten the time that the heat source is turned off, thereby preventing the cooking chamber from being excessively heated at the beginning of the cooking and reducing the actual cooking time, thereby saving energy.
