Abstract:
Provided are a vacuum cleaner that uses both alternating current (AC) power and direct current (DC) power without a separate switch module, and a control method thereof. The cleaner includes a suction nozzle sucking a cleaning target, a suction connection part connected to the suction nozzle and allowing the sucked cleaning target to pass therethrough, and a main body separated from the suction nozzle and having a dust box collecting the cleaning target, wherein the main body includes a suction force generating unit installed in the main body to generate a suction force and a power supply unit detachably provided in the main body to apply a voltage to the suction force generating unit, wherein the power supply unit supplies power to the suction force generating unit using any one of a DC voltage and an AC voltage.

Provided is a vacuum cleaner 1. The vacuum cleaner 1 according to one aspect of the present invention includes a cleaner body 10 having a suction motor 160; a suctioning portion 21 configured to be in communication with the cleaner body 10 and to suction air and dust; an installing portion 102 provided at the cleaner body 10; a battery assembly 120 separably installed at the installing portion 102, and having a battery 122; a cord reel assembly 130 separably installed at the installing portion 102 to replace the battery assembly 120, and having a power cord 140; and a controller 150 configured to control the suction motor 160 based on the assembly 120, 130 installed at the installing portion 102.
Abstract:
A home appliance (100a) is disclosed, including a motor (230), a drive unit (220) configured to drive the motor (230), a first circuit unit (610) including a main controller (210) configured to control the drive unit (220), a display unit (118), and a second circuit unit (620) including a display controller (625) configured to control the display unit (118). The first circuit unit (610) transmits wireless power to the second circuit unit (620), using a first frequency, and the second circuit unit (620) transmits data to the first circuit unit (610), using a second frequency different from the first frequency. Thereby, wireless power transmission and bidirectional communication are performed between the first and second circuit units (610, 620).
