The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner capable of cleaning the cleaner side portion.

In general, a vacuum cleaner uses a vacuum pressure generated by a vacuum motor mounted inside a main body to suck air containing foreign substances such as dust from the surface to be cleaned, and then filter the foreign substances from the air sucked inside the main body. It is a device to clean the cleaning surface. Such a cleaner is classified into a canister type vacuum cleaner in which a nozzle portion for sucking air containing foreign matter on the surface to be cleaned is connected by a connecting tube provided separately from the main body, and an upright type vacuum cleaner in which the nozzle portion is integrally formed with the main body. Then, it is classified into a manual cleaner and an automatic cleaner according to whether or not it is directly operated by the user.

On the other hand, the general automatic cleaner is a device that performs the cleaning while moving the area to be cleaned by the input program, the rechargeable battery as a power source. Since these automatic cleaners perform their own cleaning without the user's direct manipulation, they are in the spotlight among busy modern people.

The automatic cleaner determines an area to be cleaned by driving the outer side of the cleaning area surrounded by a traveling obstacle such as a wall through a sensing device installed in the main body, and plans a cleaning path for cleaning the cleaning area. Next, drive the planned cleaning route while calculating the mileage and the current position through the number of revolutions of the wheel.

Then, through the suction nozzle and the brush formed on the bottom of the automatic cleaner, the dust or the like on the surface to be cleaned is shaken off, and the scattered dust and the like are sucked to clean the surface to be cleaned.

However, in the conventional automatic cleaner as described above, since the suction port is formed on the bottom of the main body, the distance between the suction port and the surface to be cleaned is far from the corner where the floor meets the wall or the cleaning area where the vacuum cleaner is difficult to enter. There is no problem.

In addition, in order to clean the cleaning area that is not cleaned by the conventional automatic cleaner, the user has to perform additional cleaning using a separate cleaning tool or the like.

Accordingly, an object of the present invention is to provide a vacuum cleaner which is designed to solve the problem as described above, the cleaning in the corner where the floor and the wall meets or the cleaning area that is difficult to enter the cleaner. It is done.

Vacuum cleaner according to the present invention for achieving the object as described above, the base portion is provided with a suction port forcibly sucked air containing dust or foreign matter; A rotating member formed on at least one bottom of the base and rotated by a rotating means; First and second cleaning hair coupling portions formed on the rotating member; A first cleaning hair coupled to the first cleaning hair coupling portion; A second cleaning hair having a diameter smaller than the diameter of the first cleaning hair and coupled to the second cleaning hair coupling portion; And a packing member surrounding the rotating member and a part of the first cleaning hair and the second cleaning hair.

The vacuum cleaner according to the present invention has the effect of cleaning at the corner where the floor and the wall meet or at the cleaning area where the vacuum cleaner is difficult to enter. In addition, there is an effect that the surface to be cleaned is cleaned more cleanly by the side cleaning device provided with a plurality of cleaning caps.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the presented embodiments, and other inventions within the scope of the spirit of the present invention or other embodiments which are deteriorated by addition, modification, or deletion of other components can be easily proposed. Can be.

1 is a front view of an automatic cleaner according to an embodiment of the present invention, Figure 2 is a bottom view of the automatic cleaner according to an embodiment of the present invention.

1 and 2, the automatic cleaner 1 according to the present invention is formed on both sides of the main body 10 including the upper side 20 and the base 30, and both sides of the base 30. Drive wheel 31 for moving the automatic cleaner 1, suction port 32 formed on one side of the base portion 30, and auxiliary wheels 33 formed in a plurality of places of the base portion 30 And a side cleaning device 40 provided with cleaning caps 41a and 41b which protrude at least longer than the outer circumference of the main body 10.

In detail, the main body 10 has at least a suction motor (not shown), a drive motor (not shown), a filtering device (not shown), and a distance sensor (not shown). And a shock sensor (not shown) and a control unit (not shown) are accommodated. In more detail, the drive motor allows the drive wheels 31 formed on both sides of the base portion 30 to rotate through a predetermined power transmission member. And two drive motors are preferably formed corresponding to the number of the drive wheels (31). And two drive motors enable the drive wheels 31 to rotate with their respective rotational directions and rotational speeds. Through each of these drive motors, the automatic cleaner 1 is capable of traveling at the programmed travel direction and travel speed.

The suction motor rotates a suction fan (not shown). The suction force is generated by the rotation of the suction fan, and the air containing the substance is sucked into the suction port 32 by the suction force.

The filtering device filters out only those substances in the air containing the substances sucked by the suction motor. The filtered air is exhausted to the outside through the exhaust port formed on one side of the automatic cleaner (1). On the other hand, the exhaust port is preferably formed on the upper surface of the vacuum cleaner 1 in order to prevent dust from scattering from the surface to be cleaned by the exhaust machine.

A plurality of impact sensors are formed on the outer circumferential surface of the main body 10. The impact sensor detects an impact with an external obstacle when the automatic cleaner 1 runs and transmits a shock signal to the controller.

A plurality of distance detecting sensors are formed at selected portions of the outer circumferential surface of the main body 10 to detect an object outside the automatic cleaner 1, and calculate a distance between the object and the vacuum cleaner 1 to control the control unit. Send a signal with. Meanwhile, the distance calculation between the object and the automatic cleaner 1 may be performed by the controller.

The control unit includes a microprocessor and a memory for storing data to control the driving method and each component of the automatic cleaner 1. In detail, the driving method program stored in the memory is executed by using the distance information input from the distance sensor. Then, the avoidance driving is performed by using the shock signal input from the shock sensor.

In addition, the auxiliary wheel 33 is formed in one place in front of the base portion 30, two places in the center and one place in the rear. These auxiliary wheels 33 are installed in the same direction as the drive wheels 31, and rotates with the movement of the automatic cleaner (1). In detail, the auxiliary wheel 33 serves to smoothly change the self-dispersion of the automatic cleaner 1 and the traveling direction of the automatic cleaner 1. The auxiliary wheel 33 allows a predetermined gap to be formed between the base portion 30 and the surface to be cleaned. This interval prevents excessive pressure from being applied to the hair 35 to be described later to prevent breakage.

In addition, the suction port 32 is formed on any one side of the bottom surface of the base portion 30. Then, a foreign matter collecting device is formed inside the suction port 32. In detail, a cylindrical foreign material collection rotating member 34 is formed in consideration of the shape of the suction port 32. And a plurality of rows of hair 35 is planted on the outer circumferential surface of the foreign material collection rotation member 34, one end of the hair 35 is in contact with the surface to be cleaned. In addition, a rotation motor (not shown) is coupled to one end of a rotating shaft (not shown) through which the foreign material collection rotation member 34 is coupled. This rotary motor causes the foreign matter collection rotating member 34 to rotate. Therefore, the hair 35, which is planted on the outer circumferential surface of the foreign material collection rotating member 34, scrapes upward of this substance buried on the surface to be cleaned.

In addition, the side cleaning device 40 is formed at one front side of the base portion 30. Here, the reference for dividing the front and rear is based on the main direction of travel of the vacuum cleaner (1). On the other hand, the formation position of the side cleaning device 40 is not limited to only one side of the front of the base portion 30, it turns out that it can be formed on both sides. In addition, it is noted that the number of the side cleaning device 40 can be formed.

Hereinafter, the side cleaning device 40 will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view showing a side cleaning apparatus according to an embodiment of the present invention, Figure 4 is an exploded perspective view of the rotating member and the cleaning cap and packing member according to an embodiment of the present invention.

3 and 4, the side cleaning device 40 according to the present invention is embedded in the base portion 30 and coupled to the rotary motor 42 and the rotary shaft 42 having a rotary shaft 46; A rotating member 44, a bristle coupling portion 45 extending to one side of the rotating member 44, at least two or more kinds of bristle caps 41a 41b press-fitted to the bristle coupling portion 45, and A packing member 46 surrounding the rotating member 44 and the cleaning caps 41a and 41b is included.

In detail, the rotary motor 42 is embedded in the base portion 30 so that the rotary shaft 43 is rotated. It is considered that the main action of the rotary motor 42 is the action of rotating the rotary shaft 43, it can be replaced by other rotating means for rotating the rotary shaft 43.

On the other hand, the rotation direction of the rotary shaft 43 of the rotary motor 42 is considered in the action of the side cleaning device 40, and rotates in the direction of gathering from the outside to the inside with respect to the traveling direction of the automatic cleaner (1) do. In other words, when the side cleaning device 40 is formed on the front right side with respect to the traveling direction of the automatic cleaner 1, the rotating shaft 43 of the rotary motor 42 rotates from the right side to the left side. That is, it is rotated counterclockwise.

In addition, the rotating member 44 is formed in a substantially disk shape having one surface is hemispherical. In detail, a coupling groove 47 into which the rotating shaft 43 is inserted is formed on a flat surface of the rotating member 44. On the other hand, when the rotary member 44 receives a rotational force from the rotary shaft 43, in order to avoid the phenomenon, one side of the rotary shaft 43 is formed by a D-cut process and the coupling groove 47 is It is formed corresponding to the shape of the rotary shaft 43.

In addition, the outer peripheral surface of the hemispherical portion of the rotating member 44 is formed with at least one bristle coupling portion 45 is extended, preferably four bristle coupling portion 45 is formed. In detail, the bristle coupling portion 45 is coupled to the rotating member 44 to the rotating shaft 43 and the flat surface 49 of the rotating member 44 faces the bottom surface of the basal portion 30. If so, the center line of the bristle coupling portion 45 is formed to have a predetermined angle with respect to the rotating shaft 43. In more detail, the angle formed by the center line of the rotating shaft 43 and the cleaning cap coupling portion 45 is determined in consideration of the contact range between the cleaning caps 41a and 41b and the surface to be cleaned. In the present embodiment, four cleaning hair coupling portions may be referred to as first cleaning hair coupling portions to fourth cleaning hair coupling portions.

In addition, the four bristle coupling portions 45 may be disposed between any one bristle coupling portion 45 at a distance D1 between another bristle coupling portion 45 and another bristle coupling portion 45. The distance D2 is formed differently. In addition, the two bristle coupling portions 45 having a small distance between the bristle coupling portions 45 form a single bristle coupling portion set 47.

Here, although it has been suggested that two cleaning bristle coupling sets 47 according to the present invention are formed, the present invention is not limited thereto, and three or more sets may be formed. And one of the bristle coupling portion 45 is made of one bristle coupler set 47 as two, but not limited to this, it will be understood that one bristle coupler set of three can be made.

In addition, the cleaning caps (41a, 41b) is formed of two or more kinds formed of a nylon material. The classification criteria of the cleaning caps 41a and 41b are classified by the cross-sectional area. In other words, if the cutting area is large, it is classified into a thick cleaning hat 41a, and if the cutting area is small, it is classified into a thin cleaning hat 41b. In detail, one end of the cleaning caps 41a and 41b is planted by the method of press-fitting into the cleaning cap coupling unit 45. Here, the types of the cleaning caps 41a and 41b may be classified into the thick cleaning cap 41a and the thin cleaning cap 41b according to their diameters. In addition, the types of the cleaning caps 41a and 41b may be classified by their materials. In the present embodiment, the cleaning cap having a large diameter of the hair may be referred to as the first cleaning hair, and the cleaning hair having a diameter smaller than the diameter of the first cleaning hair may be referred to as the second cleaning hair. At this time, the first cleaning hair is coupled to the first cleaning hair coupling portion and the third cleaning hair coupling portion, and the second cleaning hair is coupled to the second cleaning hair coupling portion and the fourth cleaning hair coupling portion.

On the other hand, each of the cleaning cap coupling portion 45 configured in the one cleaning cap coupling portion set 47 described above is coupled to the different types of cleaning caps (41a, 41b) described above. In detail, a thick bristle 41a having a wide cross-sectional area s1 is coupled to the bristle coupling 45 at the front side based on the traveling direction v of the bristle coupling set 47, and The cleaning head coupling part 45 is coupled with a narrow cleaning head 41b having a narrow cross-sectional area s2.

Here, it will be appreciated that the method by which each of the cleaning caps are coupled to each of the cleaning cap coupling portions is determined by the cross-sectional area of each cleaning cap and the advancing direction of the cleaning cap coupling set. That is, when a plurality of bristle coupling units form one set, the thicker the bristle is coupled and the position of the bristle coupling is closer to the front of the bristle coupling unit based on the moving direction of the bristle coupling unit set. The rear is more fine bristle.

On the other hand, in the method of coupling the cleaning hair 41a, 41b and the cleaning hair coupling portion 45, the thick cleaning hair 41a and the thin cleaning hair 41b are mixed in a predetermined ratio, thereby combining one cleaning hair. Note that it can be coupled to the portion 45.

In addition, the packing member 46 is coupled to surround the rotating member 44 after the cleaning cap 41a, 41b is coupled to the cleaning cap coupling portion 45, and the cleaning cap coupling portion 45 Shrink-molded at the portion where the cleaning caps 41a and 41b are coupled. The packing member 46 prevents the cleaning caps 41a and 41b from being separated from the cleaning cap coupling portion 45, and prevents the cleaning caps 41a and 41b from being scattered when they are rotated at a high speed. do.

On the other hand, in the embodiment of the present invention, the above-described side cleaning device 40 is proposed to be formed in the automatic cleaner 1, one side around the suction nozzle of the upright cleaner and around the suction nozzle of the canister cleaner Note that it can be formed on one side.

Hereinafter, the operation of the automatic cleaner having the configuration as described above will be described with reference to the drawings.

5 is an explanatory view showing the operation of the automatic cleaner according to the embodiment of the present invention.

Referring to FIG. 5, first, when a user inputs an operating condition to an operation unit formed on one side of the automatic cleaner 1, the automatic cleaner 1 determines a cleaning area through the distance sensor. A driving method according to the program stored in the memory is selected.

In addition, the automatic cleaner 1 rotates the driving motor to drive the cleaning area determined according to the selected driving method. Then, the suction motor and the collection motor are rotated while the automatic cleaner 1 runs. Therefore, a foreign material on the surface to be cleaned is sucked through the suction port formed at one side of the base portion 30 and is sucked at the same time.

Finally, the foreign matter sucked through the suction port 32 is moved to the filtering device. Then, the clean air filtered by the foreign matter is filtered by the filter installed in the filtering device is exhausted through the exhaust port formed on one side of the automatic cleaner (1).

On the other hand, when the automatic cleaner 1 runs along the wall surface 60 of the room, the side cleaner 40 formed on one side in front of the bass unit 30 of the automatic cleaner 1 is operated. . In other words, the rotation direction v of the thick cleaning hair 41a and the thin cleaning hair 41b is rotated from left to right based on the traveling direction of the vacuum cleaner 1. Here, the left and right sides are found to be left and right with reference to the drawings. Therefore, a somewhat large dust m or foreign matter close to the wall surface is first moved to the front of the vacuum cleaner 1 by the coarse cleaning cap 41a. And somewhat small dust (n) or foreign matter is moved to the front of the automatic cleaner (1) by the thin cleaning head 41b secondary. The dust (m, n) or foreign matter moved in front of the automatic cleaner 1 is sucked into the suction port (32). Here, the above action is proposed by the difference in the cross-sectional area of the cleaning caps (41a, 41b), but the action by the difference in the material of the cleaning hair (41a, 41b) is also found to have substantially the same action. .

The vacuum cleaner according to the present invention as described above has the effect of cleaning at the corner where the floor meets the wall or at the cleaning area where the vacuum cleaner is difficult to enter. In addition, there is an effect that the surface to be cleaned is cleaned more cleanly by the side cleaning device is provided with a variety of cleaning caps.
