본 고안은 장롱통풍장치에 관한 것이며, 좀더 구체적으로 습기 및 냄새제거를 위한 환기제어회로를 갖는 장롱의 통풍장치에 관한 것이다.The present invention relates to a cabinet ventilation device, and more particularly to a ventilation device of the cabinet having a ventilation control circuit for removing moisture and odors.

종래에는 가구 특히 장롱의 통풍장치로서 광센서(CdS)등을 이용하여 장롱문을 열었을때 외부로부터의 광을 감지하여 팬모터를 구동하여 장롱내부의 공기를 환기하고, 문이 닫혔을때 팬모터의 구동을 정지하는 방식을 사용한 것이 있으나, 이 방식은 실질적으로 장롱문이 열렸을 때 즉, 환기가 필요없을 때는 환기되고 환기가 필요한 밀폐시에는 환기가 되지 않는등 환기 효율이 좋지 못했다.Conventionally, when the cabinet door is opened using a light sensor (CdS) as a ventilation device for furniture, especially a cabinet, the fan motor is driven by sensing light from the outside to ventilate the air inside the cabinet, and the fan motor when the door is closed. Although there was a method of stopping the driving of this method, the ventilation efficiency was not good, such as when the cabinet door is opened, that is, when the ventilation is not necessary, and when the ventilation is not necessary, the ventilation is not performed.

따라서 본 고안의 목적은 전술한 바와같은 단점을 제거하기 위해 장롱문이 닫혔을 때 즉 밀폐시에 일정시간 간격으로 소정시간 동안 장롱내부공기를 주기적으로 자동환기할 수 있으며 전력소모가 적은 소형모터에 의해 구동되는 환기제어회로를 갖는 장롱의 통풍장치를 제공하는데 있으며, 또한 부수적으로 도난방지를 위해 문이 열렸을 때 멜로디가 울리는 경보회로를 갖는 장롱의 통풍장치를 제공하는데 있다.Therefore, the object of the present invention is to automatically ventilate the air inside the cabinet for a predetermined time at a certain time interval when the cabinet door is closed in order to eliminate the drawbacks described above, and to a small motor with low power consumption. Provided is a ventilator of a cabinet having a ventilation control circuit driven by it, and additionally to provide a ventilator having an alarm circuit that sounds a melody when the door is opened to prevent theft.

이하 첨부도면을 참조하여 본 고안의 양호한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention with reference to the accompanying drawings in detail.

제1도는 장롱통풍장치에 사용하는 환기제어회로도이며, 이 회로는 기본적으로 타이머회로(1), 리세트회로(2), 드라이브회로(3), 모터(M), 전원밧데리(B1) 및 전원스위치(SW1)로 구성된다.1 is a ventilation control circuit diagram used in the cabinet ventilation apparatus, which is basically a timer circuit (1), a reset circuit (2), a drive circuit (3), a motor (M), a power battery (B 1 ) and It consists of a power switch (SW 1 ).

타이머회로(1)는 설정된 주기(T1)마다 설정된 주기(T1)의 펄스를 발생하는 회로로서, 통상구입가능한 타임 IC(상품명 4521 U1)상기 타임 IC의 동작주기(T1,T2)를 결정하는 시정수회로(R1, C1, R2)로 구성된다. 본 실시예에서는 예를들어 T1은 4~8시간, T2는 30초~수분으로 하는 것이 좋다.A timer circuit (1) is set period (T 1) a circuit for generating a pulse of a period (T 1) is set for each, typically, available time IC (trade name 4521 U1) cycle operation of the time IC (T 1, T 2) It consists of time constant circuits (R 1 , C 1 , R 2 ) which determine. In this embodiment, for example, T 1 is preferably 4 to 8 hours, and T 2 is 30 seconds to several minutes.

리세트회로(2)는 타이머회로(1)를 초기화하기 위해 출력(Qn)에서 발생되는 일정주기의 펄스를 성형하여 리세트신호를 발생하는 회로로서, 인버터 IC(상품명 4584 U2), 적분회로(R3, C2) 및 역전류방지 다이오드(D1, D2)로 구성된다.The reset circuit 2 is a circuit that generates a reset signal by shaping a pulse of a certain period generated at the output Qn to initialize the timer circuit 1, and includes an inverter IC (trade name 4584 U2) and an integrated circuit ( R 3 , C 2 ) and reverse current prevention diodes D 1 , D 2 .

드라이브회로(3)는 모터구동용 회로로서, 바이어스 저항(R4)과 스위칭 트랜지스터(Q1)로 구성된다.The drive circuit 3 is a circuit for driving a motor, and is composed of a bias resistor R 4 and a switching transistor Q 1 .

이상과 같이 구성된 본 고안의 장롱통풍장치의 환기제어회로는 실용성을 위해 단일칩화하여 구성하면 좋다.The ventilation control circuit of the cabinet ventilation apparatus of the present invention configured as described above may be configured as a single chip for practical use.

이하에 제3도를 참조하여 환기제어회로의 동작을 설명하면 다음과 같다. 제3도는 제1도의 ㉮~㉳ 각 부위의 신호파형을 나타내는 도면이다.Hereinafter, the operation of the ventilation control circuit will be described with reference to FIG. 3. FIG. 3 is a diagram showing signal waveforms of each region of FIG.

스위치(SW1)온시, 밧데리전원(B1)이 공급되면 타이머회로(1)의 타임 IC에서 기설정된 주기(T1)마다 기설정된 주기(T2)의 펄스가 출력단자(Qn)로 부터 발생되어 저항(R4)를 통해 트랜지스터(Q1)의 베이스에 바이어스전압이 인가되므로, 트랜지스터(Q1)가 스위칭온되어 도통하므로 모터(M)에 밧데리전원(B1)이 공급될 수 있어 모터(M)가 구동하여 환기팬을 상기 펄스주기(T2)동안 구동시킨다. 한편 상기 출력단자(Qn)에서 발생된 주기(T2)의 펄스(제3도의 ㉯는 인버터 IC(4584 U2)의 적분회로(C2, R2)통해 파형이 정형되어 리세트펄스(㉮)로서 리세트단자(RST)에 입력되므로 타임 IC가 리세트되어 초기상태로 돌아간다.When the battery power supply B 1 is supplied when the switch SW 1 is turned on, a pulse of a predetermined period T 2 is output from the output terminal Qn for each predetermined period T 1 in the time IC of the timer circuit 1. Since the bias voltage is generated and applied to the base of the transistor Q 1 through the resistor R 4 , the transistor Q 1 is switched on and conducts, so that the battery power source B 1 can be supplied to the motor M. The motor M is driven to drive the ventilation fan during the pulse period T 2 . On the other hand, the waveform of the period T 2 generated at the output terminal Qn (see FIG. 3 is formed through the integrating circuits C 2 and R 2 of the inverter IC 4548 U2) and reset pulses. The time IC is reset and returned to the initial state because the signal is input to the reset terminal RST.

이와같은 동작을 반복하므로서 설정된 주기(T1)마다 설정된 주기(T2)동안 팬모터(M)가 구동되므로 환기가 될 수 있다.By repeating such an operation, the fan motor M is driven during the set period T 2 for each set period T 1 , and thus may be ventilated.

본 고안의 장롱통풍장치는 제2도에 보인 바와같은 경보회로를 더 구비하고 있다.The cabinet ventilation apparatus of the present invention further includes an alarm circuit as shown in FIG.

이 회로는 장롱문이 열릴때 광센서(CdS)에 의해 외부의 광이 감지되면 광센서(CdS)의 저항이 변화하여 저항(R1) 및 가변저항(VR1)으로 구성된 전압분배회로에 의해 다이오드(D1)를 통해 멜로디 IC의 드라이브회로를 구성하는 트랜지스터(Q1)과 트랜지스터(Q2)를 순차도통시키므로 이때 멜로디 IC (U1)의 MT1 입력에 밧데리전원(B1)이 가해져 피에조 발진기(PZ1)가 작동하여 멜로디가 울리므로 경보하게 된다.When the outside door is detected by the light sensor (CdS) when the cabinet door is opened, the resistance of the light sensor (CdS) changes so that the voltage distribution circuit composed of a resistor (R 1 ) and a variable resistor (VR 1 ). diode (D 1) the transistor (Q 1) and the transistor (Q 2) constituting a drive circuit of the melody IC through because sequential conductive case is applied the battery power source (B 1) to the MT1 the input of the melody IC (U1) the piezoelectric oscillator (PZ1) is activated and the melody rings to alert you.

한편, 장롱문이 닫히면 트랜지스터(Q1, Q2)가 차단되어 밧데리전원(B1)의 공급이 차단되어 피에조 발진기(PE1)의 동작이 정지한다. 이 경보회로 역시 환기제어회로와 함께 실용성을 위해 단일칩화 할 수 있다.On the other hand, when the long door is closed, the transistors Q 1 and Q 2 are cut off, the supply of the battery power source B 1 is cut off, and the operation of the piezo oscillator PE 1 is stopped. This alarm circuit can also be integrated into a single chip for practical use with a ventilation control circuit.

상술한 바와같이 구성된 본 고안의 장롱통풍장치는 환기제어회로 및/또는 경보회로를 단일칩화할 수 있으므로 전력소모가 적어 밧데리로 구동되는 소형모터에 사용할 수 있으므로 장치전체의 사이즈를 소형화 할 수 있고, 제품의 신뢰성이 높고, 더욱이 설정된 시간간격으로 설정된 시간동안 반복적으로 환기팬을 자동으로 구동시킬 수 있으므로 가구 고급화에 실용성이 지대할 것으로 기대된다.The cabinet ventilation apparatus of the present invention configured as described above can be used in a small motor driven by battery because the ventilation control circuit and / or alarm circuit can be integrated into a single chip, so that the overall size of the apparatus can be reduced. It is expected that the product will be highly practical for high quality furniture because it can be operated with high reliability and can automatically drive the ventilation fan repeatedly for the set time at the set time interval.
