Then, the cleaning function and the air cleaning function in the air cleaning robot cleaner according to the present invention will be described in more detail with reference to Figure 8a to 8c of the above embodiment.

First, the portion shown by the dotted lines of FIGS. 8A to 8C represents the flow of air.

8A shows an operation relationship when the cleaning and air cleaning operation modes are driven by the control unit.

When driving the cleaning and air cleaning operation mode in the control unit 570, the air (A) containing dust or foreign matter on the ground is sucked through the cleaning air suction port 510 by the suction unit (400). The sucked air flows along the cleaning air flow path 520 and is first purified through two air purification filters 210 and 220. In the cleaning and air cleaning operation mode, the first non-return valve 310 is closed and the second, third and fourth non-return valves are opened. As a result, the air on the cleaning air flow path tube 520 is discharged to the air cleaner 100 through the cleaning air connection port 525. The air discharged through the cleaning air connection port 525 is introduced into the air cleaning flow path 120 of the air cleaner 100 through the air cleaning connection port 125. Since the third non-return valve 330 is open, the air B in the external space is sucked into the clean air flow path pipe 120 through the air cleaning suction port 110 by the suction driving device 430 and is also suctioned. Air on the main body 500 introduced through the clean air connection port 125 by the driving device 430 is also sucked onto the clean air flow path pipe 120. Air and external air introduced from the main body 500 are mixed with each other on the clean air flow path pipe 120 to be purified by the air purification filter 230. The purified air is discharged to the outside (D) through the clean air discharge port 130.

As such, air including dust on the ground is first purified from the main body 500 and secondly purified through an air cleaner, and then discharged. The air in the space generated during the cleaning process is purified through the air cleaner, thereby cleaning. It is possible to maintain a comfortable state even during performance.

8B shows the operation relationship when the cleaning operation mode is driven by the control unit.

When driving the cleaning operation mode in the control unit 570, the air (A) containing dust or foreign matter on the ground by the suction unit 400 is sucked through the cleaning air suction port 510. The sucked air flows along the cleaning air flow path 520 and is purified through two air purification filters 210 and 220. In the cleaning operation mode, the first non-return valve 310 is opened and the second, third and fourth non-return valves are closed. Therefore, the air purified through the air purification filters 210 and 220 along the cleaning air flow path pipe 520 is discharged to the outside (C) through the cleaning air discharge port 530.

Thus, in the cleaning operation mode, only the role of the cleaner is performed. The air cleaner does not need to be operated when the air in the cleaning area is not contaminated. In addition, the volume of the robot cleaner increases when the air cleaner is attached. It may be difficult to clean a narrow space. In this case, the air cleaner can be separated and the robot cleaner can be made as small as possible to clean a narrow space.

8C shows an operation relationship when the air cleaning operation mode is driven by the control unit.

When the controller 570 drives the air cleaning operation mode, the air B on the external space is sucked through the cleaning air suction port 110 by the suction driving device 430. In the air purifying operation mode, the first and second non-return valves are closed and the third and fourth non-return valves are closed, and the air sucked in flows along the air-cleaning flow path pipe 120 to form a plurality of filters in one group. Purification is performed through the air purification filter 230. The purified air is discharged to the outside (D) through the air clean discharge port 130.

As such, in the air purifying operation mode, only a function of purifying air in the external space is performed, which eliminates the need for a separate air purifier.

Furthermore, the air cleaner robot cleaner according to the present invention may be controlled by the user's wireless remote controller. For this purpose, the controller 550 may be controlled by the user's wireless remote controller through the wireless transmitter / receiver 570. It provides information and receives a control command signal from the wireless remote controller to control the operation mode of the air cleaning robot cleaner.

By using such a wireless transmission and reception device, the user can check the operation state of the air cleaning robot cleaner and operate the operation mode.
