The present invention relates to an automatic driving device for a vacuum cleaner, and more particularly, to allow the vacuum cleaner to automatically run and to be used conveniently.

In general, a vacuum cleaner is a device for cleaning dust and other foreign substances by suction force, and the suction force is generated by rotating the impeller 2 in the main body 1 as shown in FIGS. 1 to 2. The motor (3) is mounted so that the front of the main body (1), the hose (4) is detachably installed so that dust or other foreign matter can be guided into the main body (1) by the suction force. In order to remove the dust or other foreign matter that is guided to the hose (4) inside the front body 1, the paper filter (5) is built.

In addition, an exhaust filter 6 is installed at the rear of the main body 1 to remove the brush powder generated when the motor 3 is driven, and at the rear end of the main body 1, a paper filter ( 5) As the dust or other foreign matter is removed by the discharge hole 7 is formed so that only clean air is discharged to the outside, the lower surface of the main body 1 when the main body 1 moves to the front center part In addition, the front wheel 8 is rotatably installed in any direction so that the right rotation direction can be performed smoothly, and the rear wheel 9 is installed at both rear portions so that the front and rear movements of the main body 1 can be performed smoothly. .

Therefore, when the power supply button is selected from the control buttons of the handle (not shown) formed integrally with the hose 4, the motor 3 mounted in the main body 1 is driven and the impeller 2 is rotated by this driving force. The suction force is generated, and when the user faces the bottom surface to clean the suction port (not shown) connected to the hose 4, air and foreign substances are sucked together by the suction force through the hose 4 and the main body ( 1) flows into.

In this way, the air and foreign matter flowing into the main body 1 enter the paper filter 5 installed in the main body 1, and the foreign matter is removed, and only the air exits the paper filter 5 and moves to the rear of the main body 1. While cooling the motor (3).

The air cooled by the motor 3 is discharged to the discharge hole 7 formed at the rear end of the main body 1 as the impeller 2 continues to be rotated, and the brush powder generated according to the driving of the motor 3 is generated. Since is removed by the exhaust filter 6 installed inside the discharge hole (7) is actually only clean air is discharged to the outside.

On the other hand, when cleaning, the user artificially pulls and moves the main body 1 according to the cleaning position. At this time, the front wheel is installed to be freely rotatable forward and backward in the center of the front surface of the main body 1. The movement in the forward and rearward direction is carried out by (8) and is carried out by the rolling motion of the rear wheels 9 provided on the rear both sides.

However, such a general vacuum cleaner is very inconvenient to use because the user has to clean the body while moving the body for cleaning, and the bottom surface is scratched because the wheel slips when it passes over the bottom of the floor. There was a problem being hit.

The present invention was devised to solve the problem between the user, when the user selects the power supply button when cleaning, the vacuum cleaner automatically runs to facilitate the convenience and change the wheel to the track type and the bottom surface is The purpose is to prevent scratches in advance.

According to the present invention for achieving the above object, the first motor and the second motor mounted on the bottom surface of the main body for generating power, and fixed to the rotary shaft of the first motor to rotate under the driving force of the first motor The first compression ring and the second compression ring is fixed to the rotary shaft of the second motor and rotates in response to the driving force of the second motor, and the elastically variably installed by the belt tension adjusting means to the bottom of the main body, the first rotation ring and the first It is wound around a belt support coupled to the two rotary rings, and the first belt and the second compression ring and the second rotary ring which is wound around the first compression ring and the first rotary ring to move the main body while forming a track according to the rotation of the first compression ring. According to the rotation of the second compression ring is provided an automatic driving device of the vacuum cleaner of the present invention by configuring a second belt to move the main body with the first belt while forming a track.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 to 7 of the accompanying drawings.

FIG. 3 is a side view showing the main portion of the vacuum cleaner having the device of the present invention, FIG. 4 is a bottom view of the vacuum cleaner having the device of the present invention, and FIG. 5 is a cross-sectional view taken along line A-A of FIG.

6 is a side view showing the "B" partial coupling state of Figure 4, Figure 7 is a side view showing the "C" partial coupling state of FIG.

According to the present invention, the first motor 10 and the second motor 10a are mounted to one side of the bottom surface of the main body 1, respectively, so that the first compression ring 11 is attached to the rotating shaft of the first motor 10. ) And a second compression ring (11a) is fixed to the rotating shaft of the second motor (10a), the first rotary ring 12 and the second rotary ring at both ends on the other side of the bottom surface of the main body (1) A belt support 13 coupled to each other 12a is elastically installed to be variably by belt tension adjusting means, and is connected to the outer circumferential surface of the first compression ring 11 and the first rotation ring 12. Winding the belt 14, the first belt 14 is moved along the rotation of the first compression ring 11 to move the main body 1 while forming a track while the second compression ring (11a) and the second rotation ring ( The second belt 14a is wound around the outer circumferential surface of 12a so that the second belt 14a moves along the rotation of the second compression ring 11a to move the main body 1.

In the belt tension adjusting means is a plurality of concave groove 15 formed on the bottom surface of the main body 1, the support 16 fitted into the concave groove, the movable table 17 supported by the support between the, and the movement The support member 16 can be selectively fitted into the plurality of recessed grooves 15 formed in the main body 1 by being composed of a compression spring 18 which is inserted between the belt support belt 13 and the belt support 13 to have elasticity. When the moving table 17 moves forward and backward, the tension of the first belt 14 and the second belt 14a is adjusted by pressing the belt support 13 or releasing the pressing force.

In addition, a plurality of contact protrusions 19 are formed on the outer surfaces of the first belt 14 and the second belt 14a so that the contact protrusions when the first belt 14 and the second belt 14a form a track. As the body 19 contacts the bottom surface, the main body 1 is smoothly moved.

And the front of the bottom surface of the main body 1 is provided with a wheel 20 is formed with a plurality of projections (20a) on the outer circumferential surface so that the main body 1 is easily moved even at high places such as the threshold by the wheel.

Referring to the operation, effects of the present invention configured as described above in detail.

When the power supply button is selected among the control buttons of the handle formed integrally with the hose 4, cleaning is performed. At this time, the first motor 10 and the second motor 10a mounted on one side of the bottom surface of the main body 1 are also powered. The first compression ring 11 fixed to the rotation shaft of the first motor 10 and the second compression ring 11a fixed to the rotation shaft of the second motor 10a are rotated, and thus the first belt ( 14 and the plurality of contact protrusions 19 formed on the outer surface of the first belt 14 and the second belt 14a as the second belt 14a orbits in continuous contact with the bottom surface. (1) is moved.

In the above, the first belt 14 and the second belt (14a) is in the orbit is the belt support 13 is elastically installed to be variable by the belt tension adjusting means on the other side of the bottom of the main body (1), The first rotary ring 12 and the second rotary ring 12a are fitted at both ends of the belt support, respectively, and the first belt 14 has the first compression ring 11 and the first rotary ring 12 outside. Since the second belt 14a is fitted to be connected to the circumferential surface, the second belt 14a is fitted to be connected to the outer peripheral surface of the second compression ring 11a and the second rotary ring 12a.

Meanwhile, when the main body 1 moves as the first belt 14 and the second belt 14a move in orbit, if the tension of the first and second belts 14 and 14a is too weak, the first and second compression rings ( 11) Since the rotational force of 11a is not completely transmitted to the first and second belts 14 and 14a, the movement of the main body 1 is not normally performed, on the contrary, the first and second belts 14 and 14a are reversed. When the tension of the) is too strong, the first and second motors (10, 10a) is subjected to a load and various castings are deformed or the power consumption is increased, so the tension of the first and second belts (14, 14a) needs to be properly adjusted. There is.

That is, if the tension of the first and second belts 14 and 14a is too weak, the support 16 is formed in the recess groove formed in front of the recess groove formed in the front of the plurality of recess grooves 15 formed on the front surface of the main body 1. In this case, the moving base 17 is moved toward the front of the main body 1 by the distance the support is moved, and the compression spring 18 inserted between the moving base 17 and the belt support 13 is pushed. Accordingly, since the belt support 13 moves to the left in the drawing under the pressing force of the compression spring 18, the tension of the first and second belts 14 and 14a is reduced by the first and second rotation rings 12 and 12a. Get stronger.

In addition, if the tension of the first and second belts 14 and 14a is too strong, the support base 16 is provided in the recess groove formed behind the recess groove which was first inclined among the plurality of recess grooves 15 formed in the bottom surface of the main body 1. This can be inserted, but at this time, the tension is weakened because all operations are made in reverse when the tension of the first and second belts 14 and 14a described above is increased.

As described above, when there is a step on the bottom surface when the vacuum cleaner is driven by the action, the pair of wheels 20 provided in front of the bottom surface of the main body 1 are integrally formed on the outer circumferential surface. The main body is moved while being caught by the projection 20a while being rotated under the moving force of the main body 1 while easily passing over the stepped portion.

Here, the driving direction of the vacuum cleaner when the user can be adjusted to the left and right as needed, if briefly described with reference to the action for this.

If the user selects the right travel direction control button or the left travel direction control button among the control buttons of the handle integrally formed on the hose 4, the microcomputer reads the signal of the selected button and the driving direction of the first and second motors 10 and 10a. Since the driving direction of the vacuum cleaner is changed to the selected direction because it is different from each other, the circuit configuration of the control unit for this is generally widely used, so a detailed description thereof is omitted.

Therefore, the present invention is automatically operated even if the vacuum cleaner is not artificially driven, and even if there is a step on the floor, the cleaner continues to easily move beyond the step, so it is very convenient to use and the wheel is in the track type. Scratches on the floor can be prevented beforehand.
