Abstract

An air cleaner disposed in an indoor space is disclosed. The air cleaner according to an embodiment of the present invention includes a blowing device including a suction port and a discharging port, a fan motor configured to cause air flow, a purification unit installed in the blowing device to clean air, a flow conversion configured to change a flow direction of air discharged from the discharging port, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive feature information collected by the moving agent and associated with a structure of the indoor space, obtain a type of the indoor space by using the feature information, and control an operation of at least one of the fan motor and the flow conversion device by using the type of the indoor space to adjust at least one of an operation mode, a wind direction, and a wind volume.

Claims (30)

1. An air cleaner disposed in an indoor space, the air cleaner comprising:

a blower including a suction port and a discharging port;

a fan motor configured to cause air flow;

a purifier installed in the blower to clean air;

a flow converter configured to change a flow direction of air discharged from the discharging port;

a communicator configured to communicate with a moving agent moving in the indoor space;

a memory configured to store types of a plurality of indoor spaces including a plurality of zones and a plurality of cleaning information respectively corresponding to the plurality of zones, wherein each type among the types of the plurality of indoor spaces is divided into the plurality of zones and the cleaning information of each zone is a setting value of the air cleaner which enables optimal air cleaning to be performed in a corresponding zone; and

a processor configured to receive feature information collected by the moving agent and associated with a structure of the indoor space, obtain the type of the indoor space by using the feature information, and control an operation of at least one of the fan motor and the flow converter by using the type of the indoor space to adjust at least one of an operation mode, a wind direction, and a wind volume,

wherein the feature information collected by the moving agent includes a structure of a map of the indoor space and a position and a direction of the air cleaner,

wherein the types of the plurality of indoor spaces stored in the memory have different structures and different positions and directions of virtual air cleaners, and

wherein the processor is further configured to:

receive an input which sets a specific zone of the indoor space among the plurality of zones through an input unit;

obtain the type of the indoor space including the plurality of zones from the memory;

compare positions of the plurality of zones corresponding to the obtained type of indoor space with a position of the specific zone corresponding to the received input;

select the zone closest to the specific zone among the plurality of zones corresponding to the obtained type of indoor space;

obtain the cleaning information corresponding to the selected zone from the memory; and

perform intensive cleaning on the selected zone based on the cleaning information including the setting value of the air cleaner.

2. The air cleaner of claim 1 , wherein the processor adjusts at least one of the operation mode, the wind direction, and the wind volume by using the cleaning information corresponding to the type of the indoor space.

3. The air cleaner of claim 1 , wherein the processor receives situation information including at least one of zone-based air quality information and dust occurrence information collected by the moving agent and controls an operation of at least one of the fan motor and the flow converter by using the type of the indoor space and the situation information to adjust at least one of the operation mode, the wind direction, and the wind volume.

4. The air cleaner of claim 3 , wherein the processor determines the specific zone on which intensive cleaning is to be performed, based on the situation information.

5. The air cleaner of claim 4 , wherein the specific zone is a zone where air quality is worst in the indoor space.

6. The air cleaner of claim 4 , wherein the specific zone is a zone which does not reach target air quality in the indoor space.

7. The air cleaner of claim 4 , wherein the specific zone is a zone where the dust occurrence information appears.

8. The air cleaner of claim 3 , wherein

the processor obtains uniformity of air quality of the indoor space on the basis of the situation information,

when the uniformity is lower than a predetermined value, the processor adjusts at least one of the operation mode, the wind volume, and the wind direction by using the cleaning information corresponding to the type of the indoor space, and

the cleaning information corresponding to the type of the indoor space is the setting value of the air cleaner for enabling air quality of the indoor space to be uniform, based on the structure of the indoor space.

9. The air cleaner of claim 4 , wherein, when an operation of the air cleaner starts, the processor transmits a situation information collection command to the moving agent.

10. The air cleaner of claim 1 , wherein the moving agent is a robot vacuum cleaner.

11. The air cleaner of claim 2 , wherein the processor obtains at least one of the position and the direction of the air cleaner in the indoor space on the basis of the feature information and corrects the cleaning information corresponding to the type of the indoor space on the basis of at least one of the position and the direction of the air cleaner.
