The present invention relates to a vacuum cleaner, and more particularly to a robot cleaner that performs cleaning automatically.

In general, the vacuum cleaner is a device that is provided inside the cleaner body to drive the air suction device for generating an air suction force, and then suctions the air containing the foreign matter from the outside, and then separates and collects the foreign matter.

Vacuum cleaners that perform the above functions are classified into manual vacuum cleaners that are directly operated by a user, and robot cleaners that perform cleaning by themselves without the user's manipulation.

Here, the robot cleaner is a device that sucks foreign substances such as dust from the floor while traveling by itself in the area to be cleaned. In other words, the robot cleaner automatically cleans a certain area.

To this end, the robot cleaner is provided with a distance sensor for detecting a distance to an obstacle such as furniture, office supplies, walls, and the like, and left and right wheels for moving the robot cleaner.

Here, the left and right wheels are configured to rotate by the left wheel motor and the right wheel motor, respectively, so that the robot cleaner performs the cleaning of the room by changing the direction by itself according to the driving of the left wheel motor and the right wheel motor.

In addition, a lower portion of the robot cleaner, the suction unit for sucking the foreign matter from the bottom is provided.

The suction unit includes a nozzle case integrally fixed to the cleaner body, a suction inlet formed at a bottom of the nozzle case, and an edge data rotatably provided at the suction port.

Here, the edge data has a function of sweeping up foreign matter such as dust accumulated on the floor to the suction port.

However, since the conventional robot cleaner performs cleaning only by vacuum suction of dust by the suction unit, there is a problem that cleaning by the mop must be performed manually in order to finish the indoor cleaning.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a robot cleaner capable of automatically performing cleaning by dust suction and cleaning by mop.

In order to achieve the above object, the present invention, the cleaner body is provided with a dust inlet for sucking dust on the floor; Wheels rotatably provided on the cleaner body for the automatic running of the cleaner body; A driving unit provided in the cleaner body to drive the wheels; A dust collecting unit which separates and collects dust contained in the air sucked through the dust inlet; Mop mounting portion provided on the bottom of the cleaner body; And provided to the mop mounting portion to wipe the dirt on the floor surface of the room, and provides a robot cleaner comprising a mop detachable from the cleaner body.

In addition to the above configuration, the robot cleaner according to the present invention further comprises a sensor unit 400 for detecting whether the mop 300 is mounted.

In the present invention, the sensor unit 400 is operated by a magnetic force, for example, the sensor unit 400 is configured to include a reed switch 410. The sensor unit 400 detects whether the mop 300 is mounted by detecting whether the mop 200 is mounted.

In more detail, the reed switch 410 is provided in the cleaner main body 110, and operates as the mop mounting unit 200 provided with the first magnet 250 is coupled to the cleaner main body 110. It is configured to be.

Referring to FIG. 9, the reed switch 410 is a switch driven by magnetic force, and includes a pair of reeds 411 and 412 and a glass tube 413. The glass tube 413 is generally filled with an inert gas. Each of the leads 411 and 412 is formed of a magnetic material, one end of which is positioned inside the glass tube and the other end of which is positioned outside the glass tube 413.

Here, one ends of the leads 411 and 412 are installed side by side to be spaced apart from each other by a predetermined interval, and when the reed switch 410 is located in a magnetic field, the leads are connected to each other by magnetic force to detect a signal. .

Since the operation principle or structure of the reed switch 410 is variously disclosed in the related art, further description thereof will be omitted. It has its features.

Referring to FIGS. 10A and 10B, when the mop mounting unit 200 is mounted on the cleaner body 110, the reed switch 410 is positioned in the magnetic field by the first magnet 250. Accordingly, the leads 411 and 412 are connected to each other to detect the mounting of the mop 300. In addition, the mounting of the mop 300 may be displayed on the display 112a provided in the cleaner body.

Next, when the mop mounting portion 200 is separated from the cleaner body 110, the reed switch 410 is out of the magnetic field, accordingly, the leads 411, 412 are separated from each other and the mop part Removal of 300 is detected. The removal of the mop 300 may be displayed on the display 112a provided in the cleaner body.

By detecting whether the mop unit 300 is mounted as described above, when the robot cleaner 100 cleans the surface to be cleaned such as a carpet, the mop unit 200 on which the mop unit 300 is mounted is separated, and When cleaning the cleaning surface that needs to be mop, the mop mounting part 200 in which the mop part 300 is mounted may be mounted.

In addition, it is preferable that the driving force of the wheels 150 and 160 is adjusted in a state in which the mop mounting part 200 having the mop part 300 is mounted on the cleaner body 100.

The reason is that when the robot cleaner performs cleaning by mopping, the friction force between the robot cleaner and the surface to be cleaned increases, and in the state where the mop mounting unit 200 is mounted on the cleaner main body 100. It is preferable that the controller 180 increases the driving force of the wheel.

In other words, in the state in which the mop mounting unit 200 is mounted on the cleaner body 100, the controller 180 controls the driving units 151 and 161 to drive driving horsepower of the wheels 150 and 160. Increase the movement of the robot cleaner smoothly.

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.
