self-cleaner

Abstract

An autonomous cleaner comprising: a cleaner body; a cleaning module protruding from one side of the cleaner body and having casters; a crawler unit disposed on both sides of the cleaner body, And located on the rear side of the cleaning module, wherein the crawler unit includes: a driving module; a driving wheel, the driving wheel is mounted to the driving module and formed to be able to rotate by receiving a driving force from the driving module a driven wheel mounted to the drive module and disposed on the rear side of the drive wheel; and a belt formed to completely surround the drive wheel and the driven wheel in a closed loop, and configured to rotate the driven wheel when the drive wheel rotates. The cleaner main body is supported on the floor surface by the caster wheels and the driven wheels, or supported on the floor surface by the driving wheels and the driven wheels.

Description

technical field

[0001] This description relates to an autonomous cleaner with a crawler unit for moving the cleaner body. Background technique

[0002] A cleaner is a device used to perform a cleaning function by suctioning dust or foreign objects or by mopping and sweeping. Typically, the cleaner performs a cleaning function relative to the floor and includes wheels for movement. Generally, the wheels move by external force applied to the cleaner body, and are configured to move the cleaner body on the floor.

[0003] However, recently, autonomous cleaners such as robot cleaners, which perform cleaning functions while autonomously moving without manipulation by the user; The nozzle of the cleaner moves autonomously.

[0004] Such autonomous cleaners are generally provided with driving wheels that rotate by receiving driving force from a driving motor. More recently, however, belt-driven tracks have been introduced instead of drive wheels. This is because, compared to d...
