A vacuum cleaner includes a cleaner body, a suction hose mounted at a front surface of the cleaner body to suck in dust, moving wheels provided at both sides of the cleaner body, rotating to move the cleaner body and rotatably supporting the cleaner body, wheel motors connected to the moving wheels and rotating the moving wheels, a detecting unit provided in the cleaner body and sensing inclination of the cleaner body to determine whether the cleaner moves and stops, a plurality of detecting members provided at a front surface of the cleaner body and located at both sides of the suction hose to detect an obstacle, and a controller for controlling the wheel motors according to detected signals of the detecting unit and the obstacle detecting members.

Vacuum cleaner

An electronic device includes: a communication unit performing communication with a preset voice recognition server; a microphone receiving voice information; and a controller executing a specific function on the basis of voice information received through the microphone, wherein after voice information is received through the microphone, the controller determines whether a wake-up word is detected within a preset time, and when the wake-up word is detected within the preset time, the controller performs voice recognition on the voice information received before the wake-up word is detected, and when the wake-up word is not detected within the preset time, the controller does not perform voice recognition on the voice information received before the wake-up word is detected.

Electronic device and method of controlling the same

Provided is a vacuum cleaner including a cleaner body; a dust container installed at the cleaner body and of which at least a part is exposed to an outside through a front surface of the cleaner body; a cover member installed to open and close a part of the cleaner body and configured to selectively accommodate an upper portion of the dust container; a suction hose of which one side is connected to a suction part for suctioning dust and the other side is connected to a front end of the cover member; a grip portion provided at the cover member and operated to open and close the cover member; and a locking assembly provided inside the cover member and disposed at both sides based on the suction part to be restricted in the cleaner body.

A vacuum cleaner that includes: a cleaner body; a wheel; a dust container; a cover member that is configured to (i) rotate, about an axis that is outside of a plane of the cover member, between a first position and a second position and (ii) cover, based on the cover member being located at the first position or the second position, the first opening of the cleaner body and a portion of the dust container; a cover member coupling portion that couples the cover member to the cleaner body and that is configured to rotate about the second axis with the cover member; a suction nozzle that is coupled to the dust container and that is configured to guide dust into the dust container; and a display that is coupled to the cover member and that is configured to display operating information of the vacuum cleaner is disclosed.

The present invention relates to a motor driving apparatus and a home appliance comprising the same. The motor driving apparatus according to an embodiment of the present invention comprises: an inverter which converts a direct current power source of a DC stage capacitor to an alternating current power source and outputs the converted alternating power source to a motor by a switching operation; a DC stage resistance device arranged between the DC stage capacitor and the inverter; and a control unit which controls the inverter on the basis of phase current sampled by means of the DC stage resistance device, wherein the control unit controls the frequency of voltage applied to the motor or the rotation frequency of the motor to be synchronized with the sampling frequency of the phase current sampled via the DC stage resistance device. Accordingly, it is possible to accurately calculate the phase current flowing through the motor by means of the DC stage resistance device.

Motor driving apparatus and home appliance comprising same

Provided is a vacuum cleaner including a cleaner body disposed at a position distant from the ground; moving wheels rotatably installed at both sides of the cleaner body and configured to rotatably support the cleaner body; a dust container installed at a front surface of the cleaner body located at a front of the moving wheels and configured to collect suctioned dust; and a suction hose connected to the front surface of the cleaner body and through which the dust is suctioned, wherein a center of gravity of the cleaner body is located at a rear side further than a vertical extension line of a rotating center of the moving wheels, and a rear end of the cleaner body becomes closer to the ground when travel of the vacuum cleaner is stopped.

Provided is a vacuum cleaner including a base configured to form a lower surface of a cleaner body; moving wheels provided at both side surfaces of the cleaner body and rotated for travel of the vacuum cleaner and also configured to support the cleaner body to be rotated in normal and reverse directions; and a dust container installed at a front of the moving wheels and configured to collect suctioned dust, wherein the base includes a center portion; a first half portion configured to extend to be inclined upward from a front end of the center portion; and a second half portion configured to extend to be inclined upward from a rear end of the center portion, and a rotating center of the moving wheels is located between the first half portion and the second half portion.
