본 고안은 진공청소기의 속도 제어 장치에 관한것으로, 특히 진공청소기의 기동시에 속도 조절 스위치가 ″강″ 위치에 있으면 많은 전류가 인입되어 전동기나 각종 전자부품에 악영향을 끼치는 현상을 제거하기 위하여 기동속도를 서서히 증가시켜주는 진공청소기의 속도 제어 장치에 관한 것이다.The present invention relates to a speed control device for a vacuum cleaner. Especially, when the speed control switch is in the ″ strong ″ position at the start of the vacuum cleaner, a large amount of current is introduced to remove the phenomenon that adversely affects a motor or various electronic parts. It relates to a speed control device for a vacuum cleaner that gradually increases the.
제1도는 종래 진공청소기의 회로도로서 이에 도시한 바와같이, 일반적으로 위상 제어 회로로 구성하여 전동기(M)의 속도를 제어하는 속도 제어 장치(1)와, 상기 전동기(M)의 속도를 조절하기 위하여 상기 속도 제어장치(1)에 구동속도값을 인가하는 속도조절스위치(S)로 구성된것으로, 상기 속도조절스위치(S)는 가변 저항이다.1 is a circuit diagram of a conventional vacuum cleaner, and as shown therein, a speed control device 1 for controlling a speed of an electric motor M, which is generally composed of a phase control circuit, and adjusting the speed of the electric motor M. As shown in FIG. In order to configure the speed control switch (S) for applying a drive speed value to the speed control device (1), the speed control switch (S) is a variable resistor.
이와같은 종래 진공청소기의 동작과정을 설명하면 다음과 같다.Referring to the operation of the conventional vacuum cleaner as follows.
먼저, 교류전압(AC)이 인가되면 속도제어장치(1)는 속도조절스위치(S)의 위치에 따라 가변된 저항값을 인식한 후 그 저항값에 적절한 속도값을 출력하여 전동기 (M)를 구동한다.First, when an AC voltage AC is applied, the speed controller 1 recognizes a resistance value that is variable according to the position of the speed control switch S, and then outputs an appropriate speed value to the resistance value to operate the motor M. Drive.
이때, 속도조절스위치(S)가 ″강″위치에 있으면 교류전압(AC)이 인가될때 속도제어장치(1)의 속도값에 의하여 많은 전류가 공급된 전동기(M)는 강으로 구동된다.At this time, when the speed control switch S is in the " strong " position, the electric motor M to which a large amount of current is supplied by the speed value of the speed control device 1 when the AC voltage AC is applied is driven by steel.
따라서, 이와같은 종래 진공청소기는 속도조절스위치의 저항값에 의해 설정된 속도로 전동기가 구동하므로 속도조절스위치가 ″강″위치에 있을때 전원이 전동기에 인가되면 갑자기 무리한 힘으로 기동하여 많은 기동전류가 인가됨에 의해 전동기나 속도제어장치에 내장된 전자부품으로 과전류가 흘러 파손되는 문제점이 있었다.Therefore, such a conventional vacuum cleaner operates the motor at the speed set by the resistance value of the speed control switch, so when the power control is applied to the motor when the speed control switch is in the ″ strong ″ position, it suddenly starts with excessive force and a large amount of starting current is applied. As a result, there is a problem in that an overcurrent flows to an electronic component embedded in a motor or a speed controller.
본 고안은 이러한 문제점을 감안하여 진공청소기의 기동시 급속한 속도변화가 요구되어도 갑자기 큰부하가 전동기에 인가되지 않도록 전동기의 구동속도를 서서히 변화시켜 주는 진공청소기의 속도 제어 장치를 안출한 것으로, 이를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.In view of these problems, the present invention devised a speed control device for a vacuum cleaner that gradually changes the driving speed of the motor so that a sudden large load is not applied to the motor even when a rapid speed change is required when the vacuum cleaner is started. Referring to the drawings in detail as follows.
제2도는 본 고안 진공청소기의 속도 제어 장치의 회로도로서, 이에 도시한 바와같이 교류전압(AC)을 인가받아 직류 정전압을 생성하는 정전압부(11)와, 속도조절스위치(S)의 위치에 따라 부하 속도값을 생성하는 마이콤부(12)와, 그 마이콤부(12)의 부하 속도값에 따라 전동기(M)의 속도를 제어하는 속도조절부(13)로 구성한 것으로, 상기 속도조절부(13)는 상기 마이콤부(12)의 부하속도값을 저항(R1)을 통해 에미터가 접지된 트랜지스터(Q1)에 인가하고, 그 트랜지스터(Q1)의 콜렉터를 저항(R2)을 통해 트라이액(Tr)의 게이트전극(G)에 연결하며, 그 트라이액(Tr)의 주전극(T2)을 전동기(M)에 연결하고, 타측 주전극(T1)을 교류전원(AC)의 한선에 연결하여 구성한다.2 is a circuit diagram of a speed control device of a vacuum cleaner according to the present invention. As shown in FIG. 2, a constant voltage unit 11 generating a DC constant voltage by applying an AC voltage AC and a position of a speed control switch S are shown in FIG. It consists of the microcomputer part 12 which produces | generates a load speed value, and the speed control part 13 which controls the speed of the electric motor M according to the load speed value of the micom part 12, The said speed control part 13 ) Applies the load speed value of the microcomputer unit 12 to the transistor Q1 having the emitter grounded through the resistor R1, and the collector of the transistor Q1 through the resistor R2 to the triac Tr. The main electrode T2 of the triac Tr to the motor M, and the other main electrode T1 to one line of the AC power source AC. do.
이와같이 구성한 본 고안 진공청소기의 속도 제어 장치의 작용 및 효과를 제3도 본 고안 전동기 속도 제어시 신호 흐름도를 참조하여 설명하면 다음과 같다.The operation and effects of the speed control device of the vacuum cleaner of the present invention constructed as described above will be described with reference to the signal flow chart of the third motor speed control of the present invention.
먼저, 교류전압(AC)이 정전압부(11)에 인가되면 전원 트랜스(T), 브릿지 다이오드(BD)를 통해 감압되어 직류로 변환되고, 레귤레이터 집적소자(7805)에서 정전압(+5V)으로 생성되어 마이콤부(12)에 공급된다.First, when the AC voltage AC is applied to the constant voltage unit 11, the AC voltage is reduced through the power transformer T and the bridge diode BD to be converted to DC, and is generated as a constant voltage (+ 5V) in the regulator integrated device 7805. And supplied to the microcomputer 12.
이때, 속도조절스위치(S)의 위치에 따라 전압(Vcc)을 저항(R3)과 속도조절스위치(S)의 저항값으로 분압하여 0∼5V의 분압을 마이콤부(12)의 아날로그-디지탈 변환부(A/D)에 인가한다.At this time, the voltage Vcc is divided by the resistance value of the resistor R3 and the speed regulating switch S according to the position of the speed regulating switch S, and the divided voltage of 0 to 5 V is converted into analog-digital conversion of the microcomputer 12. It is applied to the part A / D.
따라서, 마이콤부(12)는 아날로그-디지탈 변환부(A/D)에 인가된 분압에 따라 1-16단계의 디지탈 신호로 변환하고, 이 디지탈신호를 인가받은 속도조절부(13)는 전동기(M)가 적정 속도로 구동하도록 전류의 흐름을 제어한다.Accordingly, the microcomputer unit 12 converts the digital signal in steps 1-16 according to the partial pressure applied to the analog-to-digital converter A / D, and the speed controller 13 receiving the digital signal receives an electric motor ( M) controls the flow of current to drive at an appropriate speed.
즉, 상기 속도조절부(13)는 마이콤부(12)의 디지탈 신호를 저항(R1)을 통해 트랜지스터(Q1)에 인가하여 트라이액(Tr)의 게이트 전극(G)에 디지탈 신호의 상수값에 대응하는 전류를 공급하므로써 주전극(T1),(T2)으로 흐르는 전류를 제어하여 전동기 (M)의 구동속도를 제어한다.That is, the speed controller 13 applies the digital signal of the microcomputer 12 to the transistor Q1 through the resistor R1 to the constant value of the digital signal at the gate electrode G of the triac Tr. The drive speed of the motor M is controlled by controlling the current flowing to the main electrodes T1 and T2 by supplying the corresponding current.
한편, 제3도 본 고안 전동기속도제어시의 신호흐름도를 참조하여 설명하면 전동기(M)를 구동하기 위해 교류 전압(AC)을 인가하면 일정시간(100msec)을 지연시켜 실행하고, 속도조정스위치(S)의 분압(아날로그 전압)을 마이콤부(12)의 아날로그-디지탈 변환부(A/D)에 인가하여 속도 상수값인 디지탈 신호로 변환한다.Meanwhile, referring to the signal flow diagram of the inventive motor speed control, FIG. 3 illustrates that when an AC voltage AC is applied to drive the motor M, a predetermined time (100 msec) is delayed, and the speed adjustment switch ( The partial pressure (analog voltage) of S) is applied to the analog-to-digital converter A / D of the microcomputer 12 to convert the digital signal into a speed constant value.
이때, 전동기의 현재속도 상수값이 요구속도 상수값 즉, 아날로그-디지탈 변환부(A/D)에 인가되어 디지탈 변환된 새로운 속도 상수값과 같거나 크면 현재속도를 요구 속도값으로 하여 속도조절부(13)에 인가하므로 전동기(M)는 현재속도를 유지하거나 감속하게 된다.At this time, if the current speed constant value of the motor is equal to or greater than the required speed constant value, that is, the new speed constant value applied to the analog-to-digital conversion unit (A / D) and digitally converted, the speed control unit sets the current speed as the required speed value. Applied to (13), the motor M maintains or decelerates the current speed.
한편, 현재속도값이 요구속도값보다 작으면 현재속도를 1단계 증가시킨 속도(현재속도+1)를 현재속도로하여 속도조절부(13)에 인가하여 전동기(M)를 구동한다.On the other hand, if the present speed value is smaller than the required speed value, the motor (M) is driven by applying the speed (current speed + 1), in which the present speed is increased by one step, to the speed adjusting unit 13 as the current speed.
이때, 요구속도값이 현재속도값보다 매우 큰값으로 많은 변화를 요구하여도 일정시간(100msec)동안 일정비율(1/16) 만큼의 속도만을 변화시킨다.At this time, although the required speed value is much larger than the current speed value, only a speed by a certain ratio (1/16) is changed for a predetermined time (100 msec).
즉, 최저속(1단)에서 최고속(16단)의 속도로 변화하려면 일정시간(100msec)×16 만큼의 시간이 지연된 후 최고속(16단)의 속도로 변화할 수 있다.That is, in order to change the speed from the lowest speed (stage 1) to the highest speed (stage 16), the predetermined time (100 msec) x 16 times may be delayed and then change to the speed of the maximum speed (stage 16).
따라서, 지연시간과 속도조절 스위치의 변환단수를 적절히 조정하면 더욱 부드러운 속도변화를 얻을 수 있다.Therefore, a smoother speed change can be obtained by appropriately adjusting the delay time and the conversion stage of the speed control switch.
이상에서 상세히 설명한 바와같이 븐 고안 진공청소기의 속도제어장치는 전동기구동시 속도를 증가시켜도 급속한 속도 변화가 발생하지 않기 때문에 구동시 과전류나 과전압으로 인한 전동기 및 전자부품의 파손을 방지하고, 속도 조절에 필요한 스위칭 소자를 보호하기 위해 각종 보호소자를 접속할 필요가 없으며, 급속한 속도 변화에 대하여 사용자의 놀라움이나 긴장등을 해소하는 효과가 있다.As described in detail above, the speed control device of the designed vacuum cleaner does not cause rapid speed change even if the speed of the electric motor is increased, thereby preventing damage to the motor and electronic parts due to overcurrent or overvoltage during driving, and There is no need to connect various protection elements to protect the necessary switching elements, and there is an effect of relieving the user's surprise or tension against the rapid speed change.
