Self-cleaning method of self-moving cleaning robot and self-moving cleaning robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-moving cleaning robots face difficulties in automatically cleaning hard-to-reach areas like dust suction ports and air ducts, leading to secondary pollution from accumulated dirt, and require cumbersome mode changes for self-cleaning processes.
Innovation Solution
A self-cleaning method for self-moving cleaning robots that includes a control system allowing automatic transition from a basic working mode to a self-cleaning mode, with increased suction force and water spray flow in a small region, performing in-situ operations or spiral walking actions to clean critical components without altering the original working mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the cleaning robot performs self-cleaning by changing working mode, then the self-cleaning function can be achieved, but the operation process becomes more cumbersome
Solution Approach 1:
The cleaning robot performs self-cleaning automatically without requiring user intervention to change working modes. The control system detects when self-cleaning is needed and automatically switches between working modes to complete the self-cleaning process, allowing the device to serve itself.
Solution Approach 2:
The control system dynamically switches between basic working mode and self-cleaning mode based on operational conditions. The working mode is not fixed but changes automatically according to the robot's needs, enabling flexible transition between cleaning operations and self-maintenance.
2Ease of manufacture
If manual cleaning of dust suction port and air duct is attempted, then some dirt can be removed, but these positions are very difficult to clean by hand and some positions cannot be cleaned
Solution Approach 1:
The robot uses its own cleaning system to clean its internal components. The water spray device and suction device work together to automatically clean the dust suction port, air duct, and other internal components that are difficult to reach by hand, eliminating the need for manual disassembly and cleaning.
Solution Approach 2:
The patent introduces a water spray as an intermediary medium to facilitate cleaning of hard-to-reach areas. The water spray device delivers cleaning fluid to internal components through the existing structure, enabling effective cleaning without direct manual access to difficult-to-reach positions.
3Reliability
If remaining pollutants are left in dust suction port or washing port, then the robot maintains its cleaning function, but the pollutants may drop onto the working surface to cause secondary pollution
Solution Approach 1:
The robot performs self-cleaning as a preliminary action before storing or ending its cleaning task. By automatically cleaning the dust suction port, washing port, and air duct before completion, the system prevents pollutants from being left in positions where they could later drop onto the working surface and cause secondary pollution.
Solution Approach 2:
The patent converts the potentially harmful accumulated dirt into a cleaning opportunity. The self-cleaning system uses water spray and suction to remove pollutants that would otherwise cause secondary pollution, transforming a harmful situation into a beneficial self-maintenance process.

AI summary
The present disclosure provides a self-cleaning method of a self-moving cleaning robot and a self-moving cleaning robot. The self-moving cleaning robot has both a basic working mode and a self-cleaning mode. When the self-moving cleaning robot needs to perform self-cleaning, the following steps are performed: step 100: controlling the self-moving cleaning robot to enter the self-cleaning mode; step 200: performing, by the self-moving cleaning robot, at least one self-cleaning action; and step 300: when at least one condition for ending the self-cleaning action is met, exiting the self-cleaning mode, the step 100 includes: adjusting parameters related to the operation of the self-moving cleaning robot while substantially maintaining the basic working mode. The present disclosure automatically clean part of the stains left at a rolling brush, a rolling brush cavity, a water suction port, a dust suction port and an air duct of the self-moving cleaning robot without changing an original working mode of the self-moving cleaning robot, and can prevent remaining pollutants from dropping onto a working surface to cause secondary pollution, is easy to operate and convenient to control, and can effectively realize a self-cleaning process of the self-moving cleaning robot.
