본 발명은 진공청소기의 진행방향에 따른 파워브러쉬 구동장치에 관련한 것으로서, 특히 먼지흡입단말의 바퀴에 광 감지기를 설치하여 바퀴의 전진 또는 후진 상태에 따라 브러쉬롤을 전진 또는 후진 시키므로써 사용자가 보다 더 효율적으로 청소할 수 있도록 한 것이다.The present invention relates to a power brush drive device according to the traveling direction of a vacuum cleaner, and in particular, by installing an optical sensor on a wheel of a dust suction terminal, the user moves the brush roll forward or backward according to the forward or backward state of the wheel. It can be cleaned efficiently.

종래의 진공청소기에서 브러쉬롤 모터의 구동장치는 도면 제 1 도의 블럭도 및 제 2 도의 상세회로도에서와 같이 나타내었다. 여기서는 먼저 사용자가 청소기 조작부에 위치하는 브러쉬롤 모터의 구동키를 조작하면, 그 키값을 읽어들이는 시스템 마이콤(1)과, 브러쉬롤 모터의 회전수를 조정하기 위한 모터 제어부(2)와, 브러쉬롤 모터(3) 등을 포함한 구성으로 되어 있다. 또, 시스템에서는 사용자의 필요에 의해 조작부의 브러쉬롤 모터 구동키를 누르면 그 신호를 마이콤(1)의 입력포트에서 읽어들인후 그 출력포트(Po)를 통해 모터 제어부(2)로 포토트라이악 구동신호를 내보내며, 그에 따라 모터제어부(2)의 동작으로 브러쉬롤 모터(3)가 구동되면서 브러쉬롤의 회전이 가능해진다.The driving device of the brush roll motor in the conventional vacuum cleaner is shown as shown in the block diagram of FIG. 1 and the detailed circuit diagram of FIG. In this case, when the user first operates the drive key of the brush roll motor located in the cleaner control unit, the system microcomputer 1 reads the key value, the motor control unit 2 for adjusting the rotation speed of the brush roll motor, and the brush. The roll motor 3 etc. are comprised. In addition, when the user presses the brush roll motor driving key on the control panel, the signal is read from the input port of the microcomputer 1 and the phototriac is driven by the motor control unit 2 through the output port Po. It emits a signal, and as a result, the brush roll motor 3 is driven by the operation of the motor control unit 2 to enable the rotation of the brush roll.

그러나, 이러한 동작에서는 흡입단말의 진행방향이 전진방향일때는 아무 문제가 없으나 후진방향일때는 브러쉬롤의 회전방향과 흡인단말의 진행방향이 서로 반대가 되어 부하가 크게 걸리며, 먼지가 제대로 흡입되지 않게 되는 문제점들이 발생하였다.However, in this operation, there is no problem when the moving direction of the suction terminal is in the forward direction, but in the reverse direction, the rotational direction of the brush roll and the moving direction of the suction terminal are opposite to each other, so that the load is largely applied and dust is not sucked properly. Problems have arisen.

본 발명은 상기의 문제점을 개선하기 위한 것으로서, 이것은 특히 흡인단말의 바퀴진행방향을 그 바퀴축과 같은 방향으로 회전되게 한 원판 및 발광, 수광소자로 된 광 감지기를 통해 그 상태를 마이콤에서 읽어 들이게 하고, 그 읽어들인 값을 판단하여 상기 진행방향에 맞는 신호를 선택 출력하게 되며, 그 출력신호에 의해 모터제어부의 정역회로망 구성의 스위치 소자를 구동시켜 브러쉬롤 모터에 흐르는 전류방향을 변화시키고, 브러쉬롤의 회전방향을 흡인단말 진행방향과 상응되게 일치시킬 수 있는 구동장치의 구성을 특징으로 하는 것이다.The present invention is to solve the above problems, which is to read the state from the microcomputer through a light sensor made of a disk and a light-emitting, light-receiving element, in particular, the wheel running direction of the suction terminal in the same direction as the wheel axis After determining the read value, the signal corresponding to the traveling direction is selected and outputted, and the output signal drives the switch element of the forward and reverse network structure of the motor control unit to change the current direction flowing to the brush roll motor, Characterized in the configuration of the drive device that can match the rotational direction of the roll corresponding to the suction terminal traveling direction.

이를 첨부도면에 의해 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

즉 도면 제 3 도에서와 같이 본 발명의 브러쉬롤(3) 모터 구동장치는 브러쉬롤(3) 모터와, 이 브러쉬롤(3) 모터의 회전수를 조정하기 위한 모터 제어부(2)와, 흡인단말의 바퀴진행 방향을 감지하는 바퀴진행방향 감지기(4)와, 청소기 조작부의 브러쉬롤 구동키값 및 상기 감지기의 출력을 읽어들여 흡인단말의 진행방향에 맞는 신호를 선택 출력하는 마이콤(1)과, 마이콤의 출력으로 브러쉬롤 모터의 전류방향을 정역 회로망으로 제어하는 모터 제어부(2)로 구성되며, 상기 바퀴진행 방향 감지기(4)는 도면 제 5 도 a와 같이 다수개의 절결구멍(41a)을 형성한 원판(41)과, 이 원판의 회전상태를 발광소자(42a)와 수광소자(42b)로 검출하는 도면 제 5 도 b의 광 감지기(42)로 구성하여 도면 제 4 도와 같은 흡인단말(6) 하부의 바퀴(7)축에 설치한후 광감지기의 출력단을 마이콤(1)의 입력포트(Pi)에 연결하여 구성한다.That is, as shown in FIG. 3, the brush roll 3 motor driving apparatus of the present invention includes a brush roll 3 motor, a motor control unit 2 for adjusting the rotation speed of the brush roll 3 motor, and suction. A wheel travel direction sensor 4 for detecting a wheel travel direction of the terminal, a microcomputer 1 for selecting and outputting a brush roll driving key value of the cleaner operation unit and a signal corresponding to the direction of travel of the suction terminal by reading the output of the sensor; It consists of a motor control unit 2 for controlling the current direction of the brush roll motor by the output of the microcomputer, the wheel progress direction detector 4 is formed a plurality of cutout holes (41a) as shown in Figure 5 a A suction terminal 6 as shown in FIG. 4 is composed of one disc 41 and a light detector 42 of FIG. 5B which detects the rotation state of the disc by the light emitting element 42a and the light receiving element 42b. ) Install the sensor at the lower wheel (7) Constitute the connection to the input port (Pi) of the comb (1).

그리고 상기의 모터 제어부(2)에 구비되는 모터 전류의 정역 방향제어 수단은 도면 제 8 도와 같이 브러쉬롤 모터(3)의 양단에 PNP 혹은 NPN 트랜지스터(Tr1-Tr4)로 되는 스위치 소자와, 이 스위치 소자를 동작시키기 위한 베이스 드라이브회로(8)로 구성되며, 여기서 상기의 스위치 소자는 도면 제10도와 같이 두개의 연동 릴레이(Ry1) (Ry2)를 릴레이 구동회로(도면에는 도시되지 않았음)에 의해 구동되게 하여서도 구성 가능하다.And the forward and reverse direction control means of the motor current provided in the motor control unit 2 is a switch element which is a PNP or NPN transistor (Tr 1 -Tr 4 ) at both ends of the brush roll motor 3, as shown in FIG. The switch element comprises a base drive circuit 8 for operating the switch element, wherein the switch element comprises two interlocking relays Ry 1 (Ry 2 ) as shown in FIG. 10 and a relay driving circuit (not shown). Can be configured to be driven by

이와같이 구성되는 본 발명의 동작은 도면 제 9 도의 흐름도에서와 같이 일단 사용자가 브러쉬롤 구동의 구동키를 눌러 브러쉬롤 모터(3)를 구동(S1 단계)시키게 되면 마이콤(1)에서는 흡인단말 바퀴진행 방향을 감지하기 위한 입력포트값(X)을 '0'으로 초기화(스텝 S2) 시키고 일정시간(여기서는 0.5초 정도)을 대기(스텝 S3)한다.In the operation of the present invention configured as described above, as shown in the flowchart of FIG. 9, once the user presses the drive key of the brush roll drive to drive the brush roll motor 3 (step S1), the suction terminal wheel proceeds in the microcomputer 1. The input port value X for detecting the direction is initialized to '0' (step S2) and waits for a predetermined time (about 0.5 seconds here) (step S3).

이때 광 감지기(42)는 도면 제 7 도에서와 같은 부호기로 구성되어 있으므로 발광소자(42a)에는 항상 일정전류(If=(vDO-vF)/Ra ; 단 vF는 발광소자의 단자전압)가 흐르게 되어 있어 흡인단말(3)의 바퀴가 회전하게 되면 다수개의 절결구멍(41a)이 뚫린 원판(41)이 회전하게 되고 그에 따라 수광소자(42b)에는 도면 제 6 도와 같이 전, 후진 방향에 대해 다른 출력이 나오게 되어 마이콤(1)의 입력포트(X)로 인가된다.At this time, since the light detector 42 is constituted by the encoder as shown in FIG. 7, the constant current (If = (vDO-vF) / Ra; however, vF is the terminal voltage of the light emitting element) always flows through the light emitting element 42a. When the wheel of the suction terminal 3 is rotated, the disc 41 having a plurality of cutout holes 41a is rotated, so that the light receiving element 42b is different from the forward and backward directions as shown in FIG. The output comes out and is applied to the input port (X) of the microcomputer (1).

이에 마이콤(1)에서는 입력포트(트랜지스터)의 값을 원판(41)이 1회전하는 주기(T)를 기준으로 일정간격(여기서는 0.2초 마다 읽도록 설정했음)으로 읽어들여(S4 단계) 그 파형의 형태에 따라 전진방향인지 혹은 후진방향인지(여기서는 주기(T)안에 두개의 펄스가 먼저 들어오는지 한개의 펄스가 먼저 들어오는지를 구분함)를 판다(S5, S7단계)하여 전진방향의 파형(도면 제 6 도의 가)일때는 마이콤(1)의 출력포트를 '하이'(HIGH)로, 후진방향의 파형(제 6 도의 나)일때는 '로우'(LOW)로 설정하여 출력(S6, S8 단계)하게 된다.Accordingly, the microcomputer 1 reads the value of the input port (transistor) at a predetermined interval (in this case, it is set to read every 0.2 seconds) based on the period T in which the disc 41 rotates once (step S4). Depending on the shape of the forward or backward direction (in this case, two pulses in the period (T) to distinguish whether or not one pulse comes first) sells the waveform in the forward direction (step S5, S7) In the case of a) of FIG. 6, the output port of the microcomputer 1 is set to 'HIGH', and in the backward direction (B of FIG. 6), the output port is set to 'LOW' and the output port is set (S6, S8). )

상기의 마이콤(1)의 출력은 베이스 드라이브 회로(8)(혹은 릴레이를 사용할 경우 릴레이 구동회로)를 동작시켜 스위치 소자의 온/오프(ON/OFF)를 제어하게 되는데 전진방향 즉 '하이'(HIGH)이면 NPN 트랜지스터(Tr2, Tr3)를 스위칭 동작시켜 브러쉬롤(3) 모터의 전류는 점선으로 된 화살표 방향을 그려진 루프(Loop1)를 따라 흐르게 하고, 후진방향 즉 '로우'(LOW)이면 PNP 트랜지스터(Tr1,Tr4)를 스위칭 동작시켜 실선으로 된 화살표 방향으로 그려진 루프(Loop2)를 따라 브러쉬롤(3) 모터으 전류가 흐르게 하여 브러쉬롤 회전방향을 흡입단말(6)의 바퀴(7) 진행방향과 같게 한다.The output of the microcomputer 1 controls the ON / OFF of the switch element by operating the base drive circuit 8 (or a relay driving circuit in the case of using a relay). HIGH) switches the NPN transistors Tr 2 and Tr 3 so that the current of the brush roll 3 motor flows along the loop Loop 1 with the dotted arrow direction, and reverse direction, that is, LOW. When the PNP transistors Tr 1 and Tr 4 are switched, the current flows through the brush roll 3 motor along the loop Loop 2 drawn in the solid arrow direction, and the rotation direction of the brush roll is changed to the wheel of the suction terminal 6. (7) Make the same direction of travel.

따라서 본 발명은 흡인단말의 바퀴진행방향과 브러쉬롤의 회전방향이 같게 되므로 바닥과 청소기의 흡인단말간의 마찰이 적어져 사용자가 손쉽게 청소할 수 있게 되며, 또한 먼지가 진행방향쪽으로 일어나므로 해서 빠른시간내 청소를 할수 있게 되는 것이다.Therefore, in the present invention, the wheel running direction of the suction terminal and the rotation direction of the brush roll are the same, so that the friction between the floor and the suction terminal of the cleaner is reduced, so that the user can easily clean it, and also dust occurs in the direction of travel in a short time. You will be able to clean.
