Of course, a brush (not shown) may be provided between the blades 134a in a spiral direction.

 In addition, in order to rotate the edge data 134, one side of the nozzle case 131 transmits the power of the edge data motor 134b and the edge data motor 134b to the edge data 134. The belt 134c is provided.

Therefore, when the rotational force of the edge data motor 134b is transmitted to the edge data 134 through the belt 134c, the edge data 134 rotates and wipes foreign substances on the floor to the suction port 132. Up.

On the other hand, the suction nozzle 130 provided to the robot cleaner according to the present invention is provided to be movable up and down on the cleaner body 110, and moves along the bottom surface with irregularities.

In more detail, when the cleaner body 110 of the robot cleaner performs cleaning while moving on the floor by the driving wheels 150 and 160, the suction nozzle 130 is in contact with the floor on which cleaning is performed. Inhale foreign substances on the floor in the state.

Then, when the robot cleaner 100 passes through the recessed portion of the floor, the suction nozzle 130 moves downward along the surface of the recessed portion to suck in foreign matter, and the robot cleaner 100 passes through the recessed portion of the floor. Then, it moves upward along the bottom surface and returns to its original position.                     

The suction nozzle 130 provided to the robot cleaner according to the present embodiment is rotatably connected to the cleaner body 110 by a hinge connection part.

Here, the hinge connection part is a first connection part (not shown) formed in the cleaner body 110, a second connection part 220 formed in the suction nozzle 130, and the second connection part 220 in the first connection part. It comprises a pin 230 to rotatably connect).

Here, the side blocking portion provided in a direction perpendicular to the surface of the blade 134a of the side blocking portions, it is preferably formed to extend longer in front than the opposite side blocking portion.

The reason for this is that dust on the bottom is more likely to spread in the direction perpendicular to the surface of the blade 134a.

Referring to Figures 1 to 7 the operation of the robot cleaner according to the present invention configured as described above are as follows.

First, when a driving signal is input to the robot cleaner 100 by a power switch or a separate remote controller provided in the cleaner main body 110, the robot cleaner 100 moves on the floor by itself along the floor of the room. Foreign substances such as accumulated dust are sucked through the suction nozzle 130.

Here, the suction nozzle 130, by the driving of the air suction device 120 in communication with the air outlet of the dust collector 140, the suction port 132 to suck the foreign matter accumulated on the indoor floor with the air. do.

At this time, the edge data 134 provided in the suction nozzle 130, the foreign matter accumulated on the floor or the foreign matter adhered to the floor is sucked more smoothly into the suction port 132, the foreign matter accumulated on the floor or attached to the floor After wiping off the foreign matter, it is swept up to the suction port 132.

The foreign matter introduced into the robot cleaner through the suction nozzle 130 is introduced into the dust collector 140 through the communication tube 133a and is then collected by the dust collector 140.                     

In addition, the air from which the foreign matter is separated from the dust collector 140 is discharged to the outside of the cleaner body 110 through the fan.

On the other hand, when the robot cleaner 100 passes the depression of the bottom, the suction nozzle 130 moves downward along the surface of the depression to suck in foreign matter.

Then, when the robot cleaner 100 passes through the depression of the bottom, the suction nozzle 130 is moved upward along the bottom surface and returned to its original position.

In more detail, the suction nozzle 130 rotates downwardly about the hinge connection part 200 by gravity, and sucks dust accumulated in the depression in contact with the surface of the depression.

In addition, when the suction nozzle 130 passes through the recessed part, the suction nozzle 130 rotates upwardly around the hinge connection part 200 to move upward, and sucks foreign substances such as dust in contact with the flat bottom.

As described above, in the process of the suction nozzle 130 sucks the dust of the floor, the dust of the floor is swept up to the suction port 132 by the blade 134a of the rotating edge data.

However, some dust is bounced tangentially to the bottom of the edge data 134 and dispersed to the side and / or rear of the suction port 132.

At this time, the dust bounced to the rear of the inlet 132 is blocked by the sweeper constituting the first blocking unit 135, the dust bounced to the side of the inlet 132 is the second blocking unit ( It is blocked by the at least one brush 136a constituting the 136, it is introduced into the suction port 132 by the air suction force.

In addition to the embodiments described above, the fact that the present invention can be embodied in other specific forms without departing from the spirit and scope will be apparent to those skilled in the art.

Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above detailed description, but may vary within the scope of the appended claims and their equivalents.

The robot cleaner according to the present invention configured as described above has the following effects.

First, according to the suction nozzle of the cleaner according to the present invention, there is no gap between the recessed part of the bottom having the unevenness and the suction nozzle, so that the foreign matter accumulated in the recessed part of the floor is easily removed and the cleaning performance is improved.

Secondly, according to the suction nozzle of the cleaner according to the present invention, a foreign matter dispersion prevention part is provided at the bottom of the suction nozzle, and dust is prevented from being thrown out by the edge data and dispersed to the outside of the robot cleaner.

Third, according to the suction nozzle of the cleaner according to the present invention, since dust is prevented from being bounced off by the edge data and dispersed to the outside of the robot cleaner, re-contamination of the already cleaned portion is prevented, and the floor is cleaned quickly.
