CLEANER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/131436
Kind Code:
A1
Abstract:
A cleaner can comprise: a fan motor for generating a suction force; an input button for receiving a user input; a first power circuit for converting alternating current power received from an external power supply, and outputting first direct current power; a second power circuit for receiving the first direct current power so as to store electrical energy, and outputting second direct current power by means of the stored electrical energy; a driving circuit for driving the fan motor by receiving the first direct current power and/or the second direct current power; a first semiconductor switching circuit for controlling the first direct current power supplied to the second power circuit; a second semiconductor switching circuit for controlling the first direct current power and the second direct current power supplied to the driving circuit; and a microprocessor for outputting a control signal for turning the first semiconductor switching circuit and the second semiconductor switching circuit ON or OFF according to the user input and a connection state of the external power supply.
