The roller 51a may be formed of a rigid body, but is not limited thereto. The brush 51b may be formed of various materials having elasticity.

The brush unit 51 can be controlled at a constant speed to keep the cleaning performance constant. When the brush unit 51 cleans the non-smooth floor surface such as a carpet, the rotation speed may be lower than that of the smooth floor surface. In this case, the brush unit 51 may further supply current to increase the rotation speed of the brush unit 51. You can keep it constant.

The dust container (60) can be mounted on the rear (R) of the main body (11). The inlet 64 of the dust container 60 can communicate with the dust inlet 50a of the brush drum unit 50. [ The dust wiped by the brush unit 51 may pass through the dust inflow path 50a and be stored in the dust container 60.

The dust detection unit 65 may be configured to include a light emitting unit 65a for emitting a beam and a light receiving unit 65b for receiving a beam. When the amount of light received by the light receiving unit 65b falls below a predetermined value, it may be determined that the dust container 60 is full of dust.

Each of the brush drum unit 50, the side brush unit 51, and the dust container 60 may be detachably attached to the main body 11 by a single assembly.

The various sensors 12, 13 may comprise a proximity sensor 12 and / or a vision sensor 13. For example, when the robot cleaner 10 travels in an arbitrary direction without a predetermined path, that is, in the cleaning system without a map, the robot cleaner 10 may travel the cleaning area using the proximity sensor 12. . On the contrary, when the robot cleaner 10 runs along a predetermined path, that is, in a cleaning system requiring a map, a vision sensor 13 may be installed to receive the position information of the robot cleaner 10 and generate a map. have. The vision sensor 13 corresponds to one embodiment of the position recognition system and can be implemented in various other ways as well.

The display unit 14 may indicate various states of the robot cleaner 10. For example, it may indicate whether the battery is charged or whether the dust container 60 is full of dust, a cleaning mode, a sleep mode, and the like of the robot cleaner 10.

The controller (not shown) may control the driving unit 20 and the cleaning unit 30 so that the cleaning task can be efficiently performed. The controller (not shown) may receive signals from various sensors 12 and 13 to avoid obstacles and change the driving mode.

In addition, when the control unit (not shown) determines that the dust container 60 is full of dust by receiving a signal from the dust detection unit 65, the controller (not shown) docks the maintenance station (not shown) to automatically collect dust from the dust container 60. Can be emptied or an alarm given to the user.

In addition, the controller (not shown) may receive a signal from the dust inflow detection unit 70 to distinguish and clean the area into which the dust flows in and the area in which the dust does not flow. For example, in the region where the dust is introduced, the cleaning efficiency can be improved by slowing the traveling speed and running speed, or by increasing the rotational force of the brush unit 51 or the suction force of the air blowing unit 52. Conversely, in areas where dust is not introduced, it may be possible to prioritize the cleaning order or reduce the number of rides.

Figure 4 is an enlarged cross-sectional view showing a blade assembly according to an embodiment of the present invention.

As shown in FIG. 4, a blade assembly 80 is positioned inside the main body 11 to guide dust inflow. Since the blade assembly 80 is installed at the rear of the brush unit 51, the brush unit 51 plays a kind of dust collecting role when the brush unit 51 sweeps out dust.

The blade assembly 80 may include a blade 82, a fixing member 81, and a support member 83.

The blade 82 is fixed to the main body 11, and serves to guide dust into the main body 11. The blade 82 may include a first portion 82a disposed above and a second portion 82b extending from the first portion 82a to the bottom side. The second portion 82b of the blade 82 has a downward slope. The second portion 82b of the blade 82 may extend to the guide portion 82d for guiding the inflow of dust from the bottom. Along the guide portion 82d, dust is introduced into the main body 11. A bent portion 82c is provided between the guide portion 82d and the second portion 82b to efficiently guide the inflow of dust by adjusting the angle between the guide portion 82d and the bottom. Although not shown in the drawings, a plurality of guide parts may be installed spaced apart.

The blade 82 is formed of a flexible material such as rubber, and may be installed to be inclined downward toward the bottom side. At this time, the end of the blade 82 may be in close contact with the bottom.

The support member 83 serves to limit the flow of the blade 82 to a predetermined range and is coupled to the blade 82. The support member 83 may be coupled to the lower side of the blade 82. The fixing member 81 is disposed to be adjacent to the blade 82 such that at least a portion of the blade 82 is in close contact with the floor. The fixing member 81 may be coupled to the upper side of the blade 82.

Insertion member 90 is located on the back of the support member 83 to be located between the support member 83 and the bottom. The blade 82 comes into contact with the floor during the driving of the robot cleaner 10. Thus, when cleaning the curved tatami floor, the end of the second portion 82b of the blade 82 is cut into the valley of the tatami floor. If you enter and hit the floor of the tatami floor, the blade could break. This not only causes damage to the tatami floor, but also causes noise during the cleaning process using the robot cleaner 10, and the insertion member 90 is for preventing this. Since the insertion member 90 is located at the rear surface of the support member 83, noise may be reduced during the driving process of the robot cleaner 10.
