Problems solved by technology

[0010] At this time, the robot vacuum cleaner 1 performs repeated cleaning strokes on the cleaning area, and dust accumulates on the above-mentioned filters 33 and 34, so that the suction performance of the suction motor 2 decreases.
[0011] That is, the suction motor 2 maintains a predetermined suction force, but the filter accumulated by dust obstructs the flow path of air sucked in from the outside. Therefore, in order to maintain a predetermined suction force, it is necessary to increase the driving force of the suction motor 2, resulting in The problem of increased energy consumption of the suction motor 2

Abstract

The present disclosure provides a robot cleaner including a suction motor installed within a main body to generate a suction force, at least two conductive plates (111, 112) spaced apart from each other to form a flowing path for external air introduced by the suction force, and a calculator (120) to measure a capacitance value between the at least two conductive plates (111, 112). A porous structure (210; 350) may be provided having at least one through hole (H) through which external air introduced by the suction force flows, a filter (33, 34; 310, 320, 330) disposed on one surface of the porous structure (210; 350) to filter dust contained in the air, and a power supply unit (220) configured to apply alternating current (AC) power to at least a partial surface of the porous structure (210, 350).

Description

technical field [0001] The invention relates to a robot vacuum cleaner and a dust detection method thereof. Background technique [0002] Typically, robots are developed for use in industry to take care of part of factory automation. Recently, the field of using robots has been expanding, and medical robots, aerospace robots, etc. have been developed, and household robots that can be used by ordinary households are also being produced. [0003] A typical example of the aforementioned household robot is a robot cleaner, which is a type of electronic equipment that cleans by sucking in surrounding dust or foreign objects while walking in a predetermined area by itself. [0004] figure 1 It is a diagram schematically showing an example of a robot cleaner in a longitudinal sectional view. [0005] A brief look at the main structure of the robot vacuum cleaner 1 is as follows, as an example, as figure 1 As shown, it can be set: a suction motor 2, which is arranged inside the ...
