AI Technical Summary

Technical Problem

When faced with complex home environments, existing floor washing robots and floor sweeping robots have single cleaning methods and insufficient applicability, making it difficult to deal with soft and hard floor mixing, wet and dry garbage mixing, and pet hair entanglement problems are serious.

Method used

A cleaning robot is designed to integrate a wet cleaning drum and a dry cleaning roller brush, combined with a negative pressure unit to provide dynamic negative pressure, adapt to different grounds through the lifting unit and sensor, realize the synchronous treatment of dry and wet garbage, and optimize the suction distribution through the fan frequency conversion control and air duct switching.

Benefits of technology

It realizes efficient cleaning of various environments such as hard floors and carpets, reduces structural complexity and volume redundancy, improves suction efficiency and energy use, simplifies maintenance operations, and improves user experience.

Abstract

The invention relates to the technical field of cleaning equipment, and provides a cleaning robot and a control method thereof.The cleaning robot comprises a body, a floor washing unit and a floor sweeping unit, the floor washing unit is arranged at the bottom of the body and comprises a roller used for wet cleaning, and the floor sweeping unit is arranged at the bottom of the body and comprises a roller used for wet cleaning; the floor sweeping unit comprises a rolling brush used for dry cleaning, the negative pressure unit is used for providing negative pressure for the floor washing unit and the floor sweeping unit, and the negative pressure unit comprises at least one draught fan. By integrating the rolling brush for dry-state cleaning and the roller for wet-state cleaning, the robot can treat various kinds of garbage at the same time or separately, the robot adapts to various environments such as hard ground and short-wool carpets, and the defects of traditional cleaning equipment with a single function are effectively overcome. Negative pressure is provided for the floor sweeping unit and the floor washing unit, the suction efficiency is improved, the structural complexity and volume redundancy of the whole machine are reduced, and therefore energy use and space configuration are optimized.
