Nozzle of cleaner and method for controlling same

Abstract

The present invention relates to a nozzle of a cleaner. A nozzle of a cleaner according to the present invention comprises: a nozzle body having suction passages for suctioning air; a first rotary cleaning part and a second rotary cleaning part which are arranged spaced apart from each other in the left and right directions below the nozzle body, and each of which is provided with a rotary plate to which a rag can be attached; a first driving device which is disposed on one side of the suction passage, among the suction passages, extending in the front-rear direction, and which is provided with a first driving motor for driving the first rotary cleaning part; a second driving device which is disposed on the other side of the suction passage, among the suction passages, extending in the front-rear direction, and which is provided with a second driving motor for driving the second rotary cleaning part; a water tank which is detachably mounted to the upper side of the nozzle body and stores water to be supplied to each of the rotary cleaning parts; a first detection part for detecting the rotation speed of the first driving motor; a second detection part for detecting the rotation speed of the second driving motor; and a control unit which receives an input of the rotation speeds of the first and second driving motors as detected by the first and second detection parts, and controls the rotation speeds of the first and second driving motors.

Description

technical field [0001] The present disclosure relates to a suction nozzle of a cleaner and a control method thereof. Background technique [0002] A cleaner is a device that sucks or wipes dust or foreign matter in the area to be cleaned for cleaning. [0003] Such cleaners can be classified into manual cleaners that clean while a user directly moves the cleaner and automatic cleaners that clean while traveling by themselves. [0004] Manual cleaners can be classified into canister cleaners, upright cleaners, hand cleaners, and stick cleaners according to the type of cleaner. [0005] These cleaners can use suction nozzles to clean the floor. Generally speaking, the suction nozzle can be used to suck air and dust. Depending on the type of nozzle, the nozzle can be attached to a mop in order to mop the floor. [0006] Korean Patent Registration 10-0405244 of prior art 1 discloses a suction port assembly for a vacuum cleaner. [0007] The suction port assembly of prior ar...

AI Technical Summary

Problems solved by technology

[0022] That is, when the rotation speeds of the drive motors arranged on both sides are different from each other, the straightness of the head coupled with the mop is reduced, and the user must apply a greater force to push the nozzle body while operating the handle.

In addition, the user's operational convenience is reduced, and the user's fatigue is inevitably increased.
