When cleaning the mop function at the same time the power is applied and driven, the clean means 16 is separated from the rotating means 13, when the cleaning of the suction function is performed only the driving means that the power is cut off (12) is mounted.

In addition, a DC voltage (VCC) supplied from the DC power supply unit 20 is input to the suction port 10 to detect whether or not the clean means 16 is adhered to the rotating means 13. When the means 16 is attached to the rotating means 13, it generates a low level detection signal, and when the clean means 16 is separated from the rotating means 13, it generates a high level detection signal. Detection means 30 for outputting to the control means to be described later is mounted.

When it is received and operated and the clean means 16 is separated from the rotating means 13, the light generated by the light emitting part 31 is absorbed to the bottom surface so that a small amount of light below a predetermined value is received and is inoperative. The receiver 32 and TR1 and the receiver 32 so that a low or high level voltage signal input from the DC power supply unit 20 is output to the control means described later in accordance with the operation or non-operation of the receiver 32. It consists of a resistor R2 connected to).

In addition, the sensing means 30 receives a DC voltage (VCC) supplied from the DC power supply means 20 to initialize a vacuum cleaner, and the clean means 16 is rotated by the sensing means 30. The low level sensing signal generated when the adhesive is attached to the means 13 is input through the input terminal P1 to generate a low level control signal, and the cleaning means 16 causes the clean means 16 to receive the low level control signal. It receives the high level detection signal generated when it is separated from the rotating means 13, generates a high level control signal, and simultaneously outputs a low or high level control signal through the output terminal P2 to the starting means. The control means 40 which outputs is connected.

In addition, in the control means 40, when the clean means 16 is adhered to the rotation means 13 by a low or high level control signal of the control means 40, the driving means 12 Is driven and the cleaning means (16) is separated from the rotating means (13) starting means for applying or cutting off the power supplied to the driving means (12) so that the driving means (12) is not driven ( 50) is connected.

In addition, the starting means 50, the transistor (TR2) and the transistor (TR2) and the non-operating or operated by receiving a low or high level control signal output from the control means 40 through the resistor (R3), Start-up unit starting or non-starting by receiving a high or low level voltage signal outputted from the DC power supply unit 20 by the non-operation or operation of TR2) through the resistor R4 and the resistor R5. And a triac 51, TR3, which is started or non-started by starting or non-starting of the starter 51.

In addition, the starter 51 is configured by the avalanche photodiode 52 that emits light or does not emit light by the non-operation or the operation of the transistor TR2, and the light emission or the non-emission of the avalanche photodiode 52. It consists of a photodial liquid 53 which is started or not started.

That is, when the clean means 16 is bonded to the rotating means 13 by the control signal of the control means 40 selectively output according to the detection signal of the detection means 30, the starting means ( At the same time as the starter 51 of the 50 is started, the triac 54 is started and powered by the driving means 12, and the clean means 16 is separated from the rotating means 13. When the starter 51 of the starting means 50 is deactivated, the triac 54 is deactivated, and the power applied to the driving means 12 is cut off so that the driving means 12 It becomes undriven.

Next, the operation and effect of the vacuum cleaner applied to the present invention configured as described above will be described.

First, when the user turns on the vacuum cleaner switch to clean the floor of the room, the DC power supply unit 20 detects the AC voltage output from the external AC power supply terminal 30 and the control means 40. And a predetermined DC voltage (VCC) required for the operation of the starting means 50, and outputs the same to the sensing means 30, the control means 40, and the starting means 50.

At this time, the power supplied from the external AC power source is also applied to the suction motor built in the vacuum cleaning body to generate the suction force.

In addition, when the DC voltage VCC is input to the sensing means 30, the light emitting unit 31 receives the DC voltage VCC output from the DC power supply unit 20 through the resistor R1. Light is emitted.

At this time, when the clean means 16 is attached to the rotating means 13, the light generated from the light emitting part 31 of the sensing unit 30 is reflected by the reflecting plate 18 of the clean means 16. A large amount of light reflected by a predetermined value or more is received by the light receiving unit 32 of the sensing unit 30.

In addition, when the light emitted from the light emitting part 31 receives a large amount of light greater than or equal to a predetermined value from the light receiving part 32 by the reflecting plate 18 of the clean means 16, the light receiving part 32 is connected to the collector end. The potential is lowered to output a low level detection signal to the input terminal P1 of the control means 40.

In addition, when a low level detection signal is input to the control means 40, the control means 40 determines that the clean means 16 is adhered to the rotation means 13 and then moves to the starting means 50. The low level control signal is output through the output terminal P2.

In addition, when a low level control signal is input to the starting means 50, the transistor TR2 of the starting means 50 is deactivated.

When the transistor TR2 of the starting means 50 is deactivated, the DC voltage VCC output from the DC power supply means 20 passes through the resistor R3 to the ground terminal through the transistor TR2. Then, a high level voltage signal is input to the starter 51 of the starting means 50.

In addition, when a high level voltage signal is input to the starter 51, the avalanche photodiode 52 of the starter is emitted, and when the avalanche photodiode 52 is emitted, the starter 51 The photo die liquid 53 is started.

When the photo die solution 53 of the starting unit 51 is started, the triac 54 of the starting unit 50 is started to supply power supplied from an external AC power source to the driving unit 12. To be applied.

In addition, when power is applied to the driving means 12, the driving means 12 is driven to the rotary means 13 and the rotary means 13 axially coupled to the driving means 12 Clean means 16 is to be rotated.

In addition, when the clean means 15 is rotated, the clean means 16 is rotated in surface contact with the floor surface of the room at the bottom of the suction port 10 by the drive means 12 to the floor of the room While performing the cleaning of the suction function to suck the dust scattered on the surface through the suction port 11, it is possible to perform the cleaning of the mop function to remove stains and dirt on the bottom surface.

On the other hand, when the clean means 16 is separated from the rotating means 13, the light emitted from the light emitting part 31 of the sensing means 30 is absorbed by the floor or the like, so that a small amount of light having a predetermined value or less The light receiving unit 32 of the sensing means 30 is to be received.

In addition, when a small amount of light below a predetermined value is received by the light receiving part 32, the potential of the collector terminal of the light receiving part 32 is increased in the light receiving part 32, and the input terminal P1 of the control means 49 is high. It will output the level detection signal.

At this time, the control means 40 determines that the clean means 16 is separated from the rotation means 13 by the high level detection signal input through the input terminal P1, and thus the starting means 50. As a result, a high level control signal is output through the output terminal P2.

In addition, when a high level control signal is input to the starting means 50, the transistor TR2 of the starting means 50 is operated to input a low level voltage signal to the starting part 51.

In addition, when a low level voltage signal is input to the starter 51, the avalanche photodiode 52 of the starter 51 becomes non-emitted and the avalanche photodiode 52 is non-emitted. The photodie solution 53 of the starting unit 51 is not started.

In addition, when the photo die liquid 53 of the starting unit 51 is deactivated, the triac 54 of the starting means 50 is deactivated and supplied from the external AC power source to the driving means 12. The power supply will be cut off.

In addition, when power supplied from an external AC power source to the driving means 12 is cut off, the driving means 12 is not driven, and the rotating means 13 axially coupled to the driving means 12 is also not rotated. Will not.

In addition, when the rotating means 13 is not rotated, the suction port body on which the rotating means 13 and the driving means 12 are mounted by the roller member 15 mounted to the rotating means 13 ( 10) It is possible to easily perform the cleaning of the suction function to suck the dust scattered on the floor surface while smoothly moving on the floor surface of the room.

Therefore, the cleaning of the floor surface of the room can be performed separately by the suction function of sucking the dust scattered on the floor surface of the room separately, as well as to clean the floor of the room more efficiently, the driving means 12 By cutting off the power applied to the) it is possible to eliminate the power consumption and noise generated by the driving of the drive means (12).

As described above, according to the driving device of the vacuum cleaner according to the present invention, when cleaning the floor of the room, the cleaning means is automatically detected whether the cleaning means is adhered to the rotating means, and the cleaning means is attached to the rotating means. Power is applied to the driving means so that the driving means for rotating the motor is driven, and when the clean means is separated from the rotating means, the power applied to the driving means is cut off so that the driving means is not driven, thereby simultaneously cleaning the mop function and the suction function. By being able to selectively perform the cleaning to be performed and the cleaning to perform the suction function, there is a very practical effect, such as to reduce the power consumption and driving noise as well as to clean the floor of the room more efficiently.
