Filter screen cleaning module and air treatment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner filter cleaning systems suffer from instability during operation, leading to poor cleaning efficiency and potential damage, with issues such as shaking brushes and excessive water consumption, and often fail to effectively recycle dirty water.
Innovation Solution
A filter screen cleaning module with a cleaning box, a screen brush assembly, and a screen brush drive gear that rotates synchronously to prevent shaking and ensure stable cleaning, while also incorporating a water inlet and outlet for efficient cleaning and dust collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brush is used to clean the filter surface, then cleaning function is achieved, but the brush tends to sway back and forth during work, resulting in poor working stability
Solution Approach 1:
The cleaning device is divided into separate functional components: a cleaning box housing, a screen brush assembly, and a drive gear assembly. This segmentation allows each component to be optimized independently - the brush assembly can be designed for cleaning effectiveness while the housing provides structural stability, resolving the contradiction between cleaning function and working stability.
Solution Approach 2:
The cleaning box serves as an intermediary structure that houses and stabilizes the screen brush assembly. The box provides a fixed reference frame and support structure, preventing the brush from swaying during operation while still allowing it to perform its cleaning function effectively.
2Reliability
If the screen brush assembly is fixed inside the cleaning box, then working stability is improved, but the drive gear may damage the filter and accumulate dust
Solution Approach 1:
The drive gear assembly is extracted from the cleaning box and positioned externally. This separation allows the drive gear to rotate the screen brush assembly without coming into direct contact with the filter screen, eliminating the risk of filter damage and dust accumulation on the drive gear while maintaining working stability through the fixed brush assembly.
Solution Approach 2:
The screen brush assembly acts as an intermediary between the drive gear and the filter screen. The drive gear rotates the brush assembly, which then contacts the filter for cleaning. This intermediary arrangement protects the filter from direct contact with the drive gear, preventing damage and dust accumulation on mechanical components.
3Productivity
If solution spray is used to clean the filter, then cleaning coverage is improved, but parts around the filter are easily sprayed and water consumption increases
Solution Approach 1:
Instead of using spray to clean the filter, the invention uses a screen brush assembly that physically contacts and brushes the filter surface. This copying of the cleaning action through direct mechanical contact provides effective cleaning coverage without the water waste associated with spray methods, and prevents water from reaching surrounding parts.
