Problems solved by technology

[0007] The aforementioned mobile intelligent cleaning robot uses a random mode when walking, which brings at least three problems: first, the purification has no directness, and the pollution source cannot be effectively eliminated in the first time; second, it will produce some areas Re-purification, but some areas have no purification defects; the third is a waste of energy, and the purification efficiency cannot be improved under the condition of limited energy supply

Embodiment 1

[0032] figure 1 It is a schematic diagram of the structure of the air purifier of the present invention; figure 2 It is a block diagram of the structure and composition of the air purifier of the present invention. like figure 1 and figure 2 As shown, an air purifier includes a main body 1 , a mobile unit 2 , an air purification unit 3 , a control unit 4 and a sensing unit 5 . The control unit 4 , the mobile unit 2 and the air purification unit 3 are arranged inside the main body 1 , and the sensing unit 5 includes an obstacle detection subunit 51 and an air pollution detection subunit 52 respectively connected to the control unit 4 . The air pollution detection subunit 52 includes a sensor that detects the degree of air pollution. The obstacle detection subunit 51 includes a front sensor 510 and a side sensor 511 . The front side sensor 510 is located at the front end of the main body in the forward direction of the air purifier; the side sensor 511 is located on one s...

Embodiment 2

[0068] The second embodiment is basically the same as the first embodiment, and the only difference is: the method for finding the pollution source. In the first embodiment, after walking a predetermined distance in the A direction and the B direction, after accurately judging the quadrant of the pollution source and the angle that the purifier needs to turn, the purifier starts to approach the pollution source at the current position and gradually approaches the pollution source in a direction. . In this embodiment, however, Figure 10 This is the second embodiment of the present invention, a schematic diagram of the air purifier looking for the pollution source. After walking a predetermined distance in the A' direction and the B' direction, after accurately judging the quadrant where the pollution source is located and the angle that the purifier needs to turn, the purifier will restart. Return to the starting point, and approach the pollution source step by step in a dire...

Embodiment 3

[0071] Embodiment 3 is an improvement on the basis of Embodiment 1 and Embodiment 2. Compared with Embodiment 1 and Embodiment 2, only one step is added, that is: in the steps of moving the purifier next to the purifier (S10) and moving to find the pollution source (S20), a purification robot is added to stop walking on the spot for purification.

[0072] like Figure 11 shown:

[0073] Step S15, a third predetermined value A3 is set in the control unit, and the air purifier control unit determines whether the detected air pollution value is greater than the third predetermined value A3 and less than the first predetermined value A1? If so, go to step S16. If not, go to step S20

[0074] In step S16, the air purifier stops moving and performs air purification on the spot.

[0075] In this embodiment, the third predetermined value A3 is larger than the second predetermined value A2 and smaller than the first predetermined value A1. At this time, it indicates that the air q...

Abstract

The invention discloses an air purifier and a method for controlling edgewise purification of the air purifier, wherein the method particularly includes the steps: 1 moving the air purifier along the edge of a space to be purified and detecting air pollution level in real time while purifying air; 2 locating a pollution source by using the air purifier and purifying air of the located pollution source when the detected air pollution value is larger than a first preset value; 3 moving the air purifier in a first preset travel mode when the detected air pollution value is smaller than a second preset value; and 4 returning to the step 1 when the air purifier moved in the first preset travel mode meets preset requirements, otherwise, continuing moving the air purifier in the first preset travel mode. By means of designing an optimal travel path, the air in a preset area is effectively purified, and purifying efficiency is improved under the condition of limited energy supply.

Description

technical field [0001] The invention relates to an air purifier and a method for controlling the same, in particular to a method for controlling the edge purification of the air purifier. Background technique [0002] With the current aggravation of air pollution and the improvement and attention of consumers to the quality of the living environment, air purifiers with various functions are used by more and more families. The principle of the air purifier: the indoor air is circulated through the fan in the air purifier. The purified air is released. The purification methods usually include physical purification methods (such as activated carbon or HEPA filters), electrostatic purification methods (such as negative ions) or chemical purification methods (such as photocatalysis or formaldehyde scavengers or agents, etc.). [0003] The traditional air purifier can only be placed in a fixed position in the room. When the air purifier is used to purify the air, the air around ...
