본 발명은, 전자레인지에서의 자동 조리 방법에 관한 것으로서, 특히 초기 송풍의 최적 소요 시간을 결정하는데 적당한 조리 방법인 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cooking method in a microwave oven, and in particular, to a cooking method suitable for determining the optimum time required for initial blowing.

종래에는, 제 1 도에 도시된 전자 레인지의 구성도에서와 같이, 자동조리가 개시되면, 그 이전에 실행하고 있었던 조리 상태에 의하여 캐비티(Cavity)(1)내에 남아 있는 고온 수증기를 방출시키기 위하여 가열은 행하지 아니하고, 송풍만을 실시하게 되는데, 이때에 소요되는 송풍 기간은 대략적으로 20초가 소요된다.Conventionally, as shown in the configuration diagram of the microwave oven shown in FIG. 1, when automatic cooking is started, in order to release the high temperature water vapor remaining in the cavity 1 by the cooking state that was previously performed. The heating is not performed, but only blowing is performed, and the blowing period required at this time takes approximately 20 seconds.

그런데, 전자레인지에 있어서, 20초이면 짧은 시간이 아닌 것이어서, 사용자가 매우 지루함을 느낄 우려가 있고, 또한 캐비티(1)내에 고온 수증기가 남아 있지 아니한 경우에는 송풍을 필요로 하지 않는 것임에도 불구하고, 종래의 방식에서는 반드시 20초를 소비하고 있었던 것으로서, 이로 인하여 불필요한 전력 소모가 가중되는 문제점이 있었다.By the way, in a microwave oven, if it is 20 seconds, it is not a short time, and there is a possibility that a user may feel very bored, and even if there is no high temperature steam remaining in the cavity 1, it does not require air blowing. In the conventional method, it is necessary to consume 20 seconds, thereby causing unnecessary power consumption.

본 발명은 이러한 점을 감안하여 캐비티(1)내에서 초기에 발생되는 고온 수증기의 양에 따라서 최적시간 동안만 송풍을 행하여 조리 시간을 가능한한 단축시켜 대기시간 및 불필요한 소비 전력을 절감할 수 있는 조리 방법을 목적으로 한 것이다.In view of the above, the present invention blows only during the optimum time according to the amount of high temperature steam initially generated in the cavity 1 to shorten the cooking time as much as possible to reduce the waiting time and unnecessary power consumption. It is for the purpose of the method.

본 방법 발명을 첨부된 도면에 따라서 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings as follows.

우선, 캐비티(1)내부를 고온 수증기로 포화시킨후, 송풍만을 실시한 경우에, 배기구(10)의 온도센서(12)의 출력 변화 상태를 제 2a 도에 나타내었다.First, when the inside of the cavity 1 is saturated with high temperature steam and only blowing is performed, the output change state of the temperature sensor 12 of the exhaust port 10 is shown in FIG. 2A.

여기에서, A점까지는 캐비티(1)내의 고온 수증기가 배출되면서 온도센서(12)에 맞닿는 것이기 때문에, 출력전압이 상승하게 되고, A점 이후 부터는 고온수증기가 모두 배출된후, 송풍에 의하여 캐비티(1)내부의 온도가 하강하기 때문에 배기 온도도 이에 따라 하강하게 된다.Here, since the hot water vapor in the cavity 1 comes into contact with the temperature sensor 12 while the hot water vapor in the cavity 1 is discharged, the output voltage is increased, and after the hot water vapor is discharged from the A point, the cavity (by blowing) 1) Since the internal temperature decreases, the exhaust temperature also decreases accordingly.

즉, 변곡점인 A점을 찾아서 고온 수증기가 모두 배출된 시점으로 규정 지을수가 있다.That is, it can be defined as the point of inflection point A, which is the point where all the high temperature steam is discharged.

제 1 도에서, 미설명 부호 2는 턴테이블(Turn table), 3은 음식물, 4는 마그네트론, 5는 도어, 6은 전원공급회로(Power Supply) 7은 스터러팬(stirror Fan), 8,9는 흡기구, 11은 콘트로울러(Controller)를 각각 표시한다.In FIG. 1, reference numeral 2 denotes a turntable, 3 diets, 4 magnetrons, 5 doors, 6 power supply circuits, 7 a stirror fan, and 8 and 9 Intake vents 11 indicate controllers, respectively.

본 발명에 있어서, 초기 송풍기간을 결정하는 방법에 대한 설명은 제 2b 도 및 제 3 도에 따라서 설명한다. 제 2b 도에 나타낸 바와같이, (a)의 경우는 캐비티(1)내부에 고온 수증기가 다량으로 남아 있었던 경우로서, K초 간격으로 샘플링 한 센서 전압치(Vn-k),(Vn)의 차이가 기준치(V)보다 작아 졌을때에 제 3 도의 플로우 챠아트로 나타낸 바와같이 송풍 기간을 종료하고 가열을 개시한다.(제 2a 도의 B점 해당)In the present invention, a description of the method for determining the initial blowing period is described with reference to FIGS. 2B and 3. As shown in FIG. 2B, in the case of (a), a large amount of high temperature water vapor remains in the cavity 1, and the difference between the sensor voltage values V nk and V n sampled at intervals of K seconds. When is smaller than the reference value (V), as shown by the flow chart of FIG. 3, the air blowing period ends and heating starts (corresponding to point B of FIG. 2a).

b의 경우는 캐비티(1) 내부에 고온은 수증기가 초기부터 남아 있지 않은 경우로서, 전압 변환값(Vn-k-Vn)이 처음부터 작은 값이므로, 송풍기간 없이 곧바로 가열 상태로 들어 간다(제 2b 도의 C점 해당).In the case of b, since the high temperature inside the cavity 1 does not have water vapor remaining from the beginning, and the voltage conversion value V nk- V n is a small value from the beginning, it enters the heating state immediately without a blowing period. For point C in Figure 2b).

이상에서와 같이 본 발명은 캐비티(Cavity) 내부의 초기 고온 수증기의 양에 따라 최적기간 동안만 송풍을 행하여 조리 기간을 단축할 수가 있는 것이어서, 조리중 대기 시간 및 불필요한 소비 전력을 절감할 수 있는 효과를 제공하는 것이다.As described above, according to the present invention, it is possible to shorten the cooking period by blowing air only during the optimum period according to the amount of initial high temperature water vapor inside the cavity, thereby reducing the waiting time and unnecessary power consumption during cooking. To provide.
