Abstract

The combination type electronic range provides dual sounds for heater and microwave oven operations. A microprocessor (1) operates a microwave oven function if the priority data is set for it, but generates a deep sound with a buzzer driving circuit (6) if the next state data does not exist. When the priority is set for a heater function, the heater operation is performed, but if the next state data does not exist, a buzzer sound is provided by a buzzer driving circuit (7).

본 발명은 콤비네이션(Combination)기능을 가진 전자레인지에 관한 것으로, 특히 마이크로웨이브와 히이터구동시 가열방법을 선별할 수 있도록 부저의 구동을 이원화 한 전자레인지의 마이크로웨이브, 히이터구동시 부저음 이원화 방법에 관한 것이다.The present invention relates to a microwave oven having a combination function, and more particularly, to a method for dualizing a microwave and a buzzer when the heater is driven by dualizing the operation of the buzzer so as to select a heating method when driving the microwave and the heater. will be.

종래의 전자레인지에 있어서는 제1도에 도시한 바와같이, 마이크로웨이브, 히이터의 구동이나 요리데이타 선택시 단일 부저구동회로를 통해 상태가 감지되는 것으로, 키이선택시에는 단음이 출력되고, 종료나 에러발생시에는 장음이 출력되었다.In the conventional microwave oven, as shown in FIG. 1, the state is sensed through a single buzzer drive circuit when the microwave and the heater are driven or when the cooking data is selected. When generated, the long sound was output.

그런데 상기와 같은 종래의 부저구동에 있어서는 히이터와 마이크로웨이브의 혼용사용시 음의 길고 짧음으로 구별되지 못하게 되는 결함이 있었다.However, in the conventional buzzer driving as described above, there is a defect that cannot be distinguished by a long and short sound when the heater and the microwave are mixed.

본 발명은 이와같은 종래의 결함을 감안하여 소프트웨어적으로 부저음을 이원화하여, 히이터요리와 마이크로웨이브요리에 따라서 부저음을 구별하도록한 전자레인지의 마이크로웨이브, 히이터구동시 부저음 이원화벙법을 창안한 것으로, 이를 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The present invention, in view of the above-mentioned conventional defects, invented the buzzer sound dualization method for microwave and microwave operation of the microwave oven to distinguish the buzzer sound according to the heater dish and the microwave dish. When described in detail with the accompanying drawings as follows.

제2도는 본 발명 전자레인지의 부저음 이원화에 대한 블럭도로서 이에 도시한 바와같이, 전원회로(4), 릴레이구동회로(3), 래세트회로(2)에 의해 구동되는 마이크로프로세서(1)가 키이매트릭스(5)의 상태를 스캔하여, 부저음 구동회로(6)(7)를 제어하게 구성한 것이다.2 is a block diagram of the buzzer dualization of the microwave oven according to the present invention. As shown therein, a microprocessor 1 driven by a power supply circuit 4, a relay drive circuit 3, and a reset circuit 2 is provided. The state of the key matrix 5 is scanned to control the buzzer driving circuits 6 and 7.

제3도는 본 발명 부저음 구동회로(6)(7)에 대한 상세회로도로서 이에 도시한바와같이, 상기 마이크로프로세서(1)의 출력이 바이어스저항(R1-R4)을 통해 트랜지스터(Q1)을 제어하여 부저(BZ)를 구동하게 구성한 것이다.FIG. 3 is a detailed circuit diagram of the buzzer driving circuits 6 and 7 of the present invention. As shown therein, the output of the microprocessor 1 controls the transistor Q1 through the bias resistors R1-R4. The buzzer BZ is driven.

이와같이 구성된 본 발명을 부저음 이원화에 대한 신호흐름도인 제4도에 의해 설명하면 다음과 같다.The present invention configured as described above will be described with reference to FIG. 4, which is a signal flow diagram for buzzer dualization.

우선순위가 마이크로웨이브로 되면, 마이크로웨이브 요리를 수행하면서 데이타를 ″0″으로 될때까지 감소시키고, 다음 상태의 수행데이타를 판별하여, 있으면 상기 우선순위데이타가 마이크로웨이브 데이타인지를 판별하여, 더이상 수행할 마이크로웨이브의 데이타가 없으면 마이크로웨이브의 부저구동회로(6)를 구동하여 일정시간동안, 비프(Beep)음을 발생시킴에 따라 마이크로웨이브의 요리상태가 감지된다.When the priority becomes microwave, while performing microwave cooking, the data is reduced until it becomes ″ 0 ″, and the performance data of the next state is determined, and if so, the priority data is discriminated to determine whether it is microwave data, and no further execution is performed. If there is no microwave data, the microwave buzzer driving circuit 6 is driven to generate a beep sound for a predetermined time, thereby detecting the cooking state of the microwave.

여기서 상기 부저구동회로(6)의 구동은 제3도에 도시한 바와같이, 마이크로프로세서(1)의 고전의 출력이 바이어스저항(R1)(R2)(R4)을 통해 트랜지스터(Q1)을 턴온시킴에 따라 부저(BZ)의 단자(D)에 저전위가 인가되며, 이의 저전위가 바이어스저항(R1)(R2)를 통해 트랜지스터(Q1)를 턴온시킨다.In this case, as shown in FIG. 3, the high output of the microprocessor 1 turns on the transistor Q1 through the bias resistors R1, R2, and R4, as shown in FIG. 3. Accordingly, a low potential is applied to the terminal D of the buzzer BZ, and the low potential thereof turns on the transistor Q1 through the bias resistors R1 and R2.

이때 부저(BZ)의 단자(D)에는 마이크로프로세서(1)의 출력측으로부터 저항(R3)을 통해 고전위가 인가되여, 이의 고전위가 바이어스저항(R1)(R2)을 통해 트랜지스터(Q1)를 턴온시킨다.At this time, a high potential is applied to the terminal D of the buzzer BZ through the resistor R3 from the output side of the microprocessor 1, and the high potential thereof is applied to the transistor Q1 through the bias resistors R1 and R2. Turn on

이때 부저(BZ)가 상기와 같이 발진함에 따라 비프음이 출력되어 사용자에게 마이크로웨이브의 요리상태를 감지시키는 것이다.At this time, as the buzzer BZ oscillates as described above, a beep sound is output to detect the cooking state of the microwave by the user.

그리고 마이크로프로세서(1)로부터 저전위가 출력되어 트랜지스터(Q1)를 턴온시킴으로써 부저 구동회로(6)가 오프된다.The low potential is output from the microprocessor 1, and the buzzer driving circuit 6 is turned off by turning on the transistor Q1.

또한 우선순위 데이타가 히이터로 되면, 세트된 데이타로 요리가 종료될때까지 히이터요리를 수행하고, 다음상태의 수행데이타를 판별하여, 있으면 상기 우선순위데이타가 마이크로웨이브인지를 다시 판별하며, 더이상 수행할 마이크로웨이브의 데이타가 없으면 히이터의 부저구동회로(7)를 구동하여 일정시간동안 비프음을 발생시킴에 따라 히이터의 요리상태가 감지된다.When the priority data becomes the heater, the heater is cooked until the end of cooking with the set data, the performance data of the next state is determined, and if so, the priority data is again determined to be microwave, and it is no longer performed. If there is no microwave data, the buzzer drive circuit 7 of the heater is driven to generate a beep sound for a predetermined time, thereby detecting the cooking state of the heater.

이후 마이크로프로세서(1)의 저전위출력으로 상기와 같이 부저구동회로(7)를 오프시킨다.After that, the buzzer driving circuit 7 is turned off as described above with the low potential output of the microprocessor 1.

이상에서 상세히 설명한 바와같이 본 발명은 부저를 이원화하여 히이터와 마이크로웨이브 사용시 고유의 부저음을 출력하므로 혼동의 염려가 제거되어 사용자에 편리함을 제공할 수 있는 효과가 있다.As described in detail above, the present invention outputs a unique buzzer sound when using a heater and a microwave by dualizing the buzzer, thereby eliminating the fear of confusion, thereby providing convenience to the user.
