The electric field generating plate 10 Is installed at a predetermined part of the refrigerator, and the food is placed on the upper portion of the refrigerator so that the food positioned at the upper portion is influenced by the electric field lines irradiated from the electric field generating plate 10 so that the freshness of the food itself is improved by molecular activation in the food. It is a device that can be greatly extended.

그러나 이와같은 전기장 발생장치는 상기 고압트랜스(11)의 이차측에 항상 일정한 전압(600V)에 따른 전기장이 유도되는 관계로, 특히 식품중 김치를 숙성(맛있는 정도)시키고자 할 경우에는, 김치량에 관계없이 항상 일정하게 조사되는 전기량에 따른 결과로, 김치량이 많은 경우에는 그 숙성시기가 빨리 도래하고, 김치량이 적은 경우에는 그 숙성시기가 늦어지게 되는 문제점이 발생되었다.However, such an electric field generating device is always induced on the secondary side of the high-voltage transformer 11 according to a constant voltage (600V), especially if you want to ripen (delicious) kimchi in food, As a result of the amount of electricity irradiated constantly, irrespective of the amount of kimchi, when the amount of kimchi is large, the ripening time arrives quickly, and when the amount of kimchi is small, the ripening time is delayed.

본 발명은 상기한 문제점을 해결하고자 안출된 것으로, 본 발명의 목적은 김치의 량에 따라 전기장의 세기를 가변하여 줄 수 있도록 하여 김치량에 따른 숙성지연의 기간을 제어할 수 있도록 한 전기장 발생장치를 제공하는 데에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide an electric field generating apparatus to control the duration of the aging delay according to the kimchi amount by varying the strength of the electric field according to the amount of kimchi. To provide.

It is installed in a predetermined portion to detect the weight of the object to be measured, it is characterized by consisting of a microcomputer to detect the weight and selectively control the voltage applied level to the electric field generating plate accordingly.

이하, 첨부된 도면에 의거하여 본 발명을 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

제1도는 본 발명에 따른 개략적인 회로도를 나타낸 것으로, 교류입력(AC)이 고압트랜스(TS)의 일차측에 인가되도록 접속하고, 상기 고압트랜스(TS)의 이차측 권선(1000볼트용)에 있어서, 800볼트용, 600볼트용 중간탭을 마련하고 상기 1000볼트용 권선이 릴레이(RL3)의 스위치(S3) 및 저항(R1)을 통해 전기장 발생판(1)에 연결되고, 상기 800볼트용 탭에서 인출된 선이 릴레이(RL2)의 스위치(S2) 및 저항(R2)을 통해 상기 전기장 발생판(1)에 연결되며, 상기 고압트랜스(TS)의 이차측 600볼트용 탭에서 인출한 선이 릴레이(RL1)의 스위치(S1) 및 저항(R3)을 통해 상기 전기장 발생수단(1)에 접속된다. 또한 상기 고압트랜스(TS)의 이차측 타단의 권선(0볼트)의 저항(R4)을 통해 고압트랜스(TS)의 일차측의 일권선과 접속된다.1 is a schematic circuit diagram according to the present invention, and is connected so that an AC input AC is applied to the primary side of the high voltage transformer TS and connected to the secondary side winding (for 1000 volts) of the high voltage transformer TS. In order to provide an intermediate tap for 800 volts and 600 volts, the 1000 volt winding is connected to the electric field generating plate 1 through the switch S 3 and the resistor R 1 of the relay RL 3 , The wire drawn from the 800 volt tap is connected to the electric field generating plate 1 through the switch S 2 and the resistor R 2 of the relay RL 2 , and 600 volts of the secondary side of the high voltage transformer TS. The wire drawn out from the tap is connected to the electric field generating means 1 via the switch S 1 and the resistor R 3 of the relay RL 1 . In addition, it is connected to the primary winding of the primary side of the high voltage transformer TS through the resistor R 4 of the winding (0 volt) of the other end of the secondary side of the high voltage transformer TS.

또한, 상기 스위치(S1~S3)들을 온, 오프 구동하는 각각의 릴레이(RL1~RL3)는 각각의 인버터(I1~I3) 및 다이오드(D1~D3)를 통해 본 발명에 따른 소정 프로그램을 적재한 원칩 마이컴(2)의 출력포트(O1~O3)에 각각 접속되며, 상기 마이컴(2)의 입력포트(PI)에는 중량감지소자(WS), 저항(R5)(R6) 및 콘덴서(C1)로 이루어진 회로가 접속되어, 제2도에 도시된 바와 같이 전기장 발생판(1)의 소정부위에 설치되는 중량감지소자(WS)는 용기(4)내에 투입된 김치(5)의 중량을 검출하는데 중량이 클수록 중량감지소자(WS)의 자체저항은 감소하고, 이로 인해 상기 중량감지소자(WS)와 저항(R6)에 따른 분배전압, 곧 마이컴(2)의 입력포트(PI)의 입력전압이 변화(전압이 높아짐)를 가져오게 되어 이를 인식한 마이컴(2)은 현재의 김치중량을 파악하여 상기 릴레이(RL1~RL3)를 구동제어한다.In addition, each of the relays RL 1 to RL 3 driving the switches S 1 to S 3 on and off is viewed through the respective inverters I 1 to I 3 and the diodes D 1 to D 3 . It is connected to the output port (O 1 ~ O 3 ) of the one-chip microcomputer (2) loaded with a predetermined program according to the invention, respectively, the input port (PI) of the microcomputer (2), the weight sensing element (WS), the resistance (R) 5 ) A circuit composed of (R 6 ) and a condenser (C 1 ) is connected, and as shown in FIG. 2, the weight sensing element (WS) provided at a predetermined portion of the field generating plate (1) is a container (4). In order to detect the weight of the kimchi (5) put in the larger the larger the self-resistance of the weight sensing element (WS) is reduced, and thus the distribution voltage according to the weight sensing element (WS) and the resistance (R 6 ), that is, micom ( 2) the microcomputer (2) the input voltage of the input port (PI) is led to a variation (the voltage increases) in this recognition is the weight to identify the current kimchi relay (RL 1 RL ~ 3) And it controls the same.

따라서, 김치량이 많을 때에는 큰 유도전기장을 조사하여 김치의 숙성에 따른 기간연장에 대응하도록 하며 김치량이 적을 때에는 적은 유도전기장으로 김치의 숙성의 지연을 김치량을 따라 조절할 수 있는 것이다.Therefore, when there is a large amount of kimchi, a large induction electric field is investigated to cope with the extension of the length of kimchi, and when the amount of kimchi is small, a small induction electric field can control the delay of ripening of kimchi according to the amount of kimchi.

제3도는 본 발명의 제어흐름도를 나타낸 것으로, 이를 토대로 본 발명의 작용 및 효과를 설명한다.Figure 3 shows the control flow chart of the present invention, the operation and effect of the present invention will be described based on this.

전원(AC) 인가되고, 전원공급부(3)를 통해 본 발명에 따른 회로에 전원이 투입되면, 마이컴(2)은 중량감지소자(WS)를 통해 입력포트(PI)로 입력되는 김치의 양에 따른 중량신호를 읽어들인다. 여기서 김치의 중량이 소정무게(3kg) 이상이 아니라면, 곧 3kg 미만이면 출력포트(O1)로 하이레벨 신호를 출력하여 릴레이(RL1)를 통전시킴으로써, 그 스위치(S1)는 온되고, 결과적으로 고압트랜스(TS)의 이차측에는 600볼트용 탭을 통해 유기된 600볼트의 전압이 전기장 발생판(1)으로 전기장을 유도시킨다.When power (AC) is applied and power is supplied to the circuit according to the present invention through the power supply unit 3, the microcomputer 2 is applied to the amount of kimchi that is input to the input port PI through the weight sensing element WS. Read the weight signal accordingly. Here, if the weight of the kimchi is not more than a predetermined weight (3kg), if it is less than 3kg, the switch S 1 is turned on by outputting a high level signal to the output port O 1 and energizing the relay RL 1 . As a result, a voltage of 600 volts induced through the 600 volt tab on the secondary side of the high voltage transformer TS induces an electric field to the electric field generating plate 1.

한편, 김치의 중량이 3kg 보다 크고 5kg 보다 적은 것으로 판단되면, 출력포트(O2)로 하이레벨 신호를 출력하여 릴레이(RL2)를 통전시킴으로써 그 스위치(S2)가 온되어, 전기장 발생판(1)에는 800볼트의 전기장이 유도된다.On the other hand, if it is determined that the weight of the kimchi is greater than 3kg and less than 5kg, the switch S 2 is turned on by outputting a high level signal to the output port O 2 and energizing the relay RL 2 to generate the electric field generating plate. In (1), an electric field of 800 volts is induced.

또한, 중량검출결과 5kg 이상이 감지되면, 출력포트(O3)로 하이레벨 신호를 출력하여 릴레이(RL3)를 통전시킴으로써 그 스위치(S3)가 온되어 600볼트의 전압에 따른 전기장이 전기장 발생판(1)으로 유도된다.In addition, if more than 5kg is detected as a result of the weight detection, by outputting a high-level signal to the output port (O 3 ) and energizing the relay (RL 3 ), the switch (S 3 ) is turned on, the electric field according to the voltage of 600 volts Guide plate 1 is guided.

이상에서와 같이 본 발명은 김치량에 따라 자동으로 전기장으로 세기를 가변하여 줌으로써 김치숙성의 지연 효과를 일정하게 관리할 수 있는 유용한 발명이다.As described above, the present invention is a useful invention that can constantly manage the delay effect of kimchi ripening by automatically varying the intensity with the electric field according to the kimchi amount.
