Condenser Cleaning Net With Reversing Rollers for Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensers in refrigerators and heat exchangers accumulate dust and debris, leading to decreased performance and potential breakdown due to inefficient cleaning methods.
Innovation Solution
An automatic condenser cleaner with a net, rollers, and brushes that continuously clean dust from condensers by alternating the direction of the net movement between rollers, ensuring thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning methods are used for condensers, then device complexity is reduced, but cleaning effectiveness and productivity deteriorate
Solution Approach 1:
The system uses the condenser fan's existing airflow to automatically move the cleaning net through the condenser fins, allowing the condenser system to clean itself without external manual intervention. The brush automatically contacts and cleans the net as it moves, creating a self-sustaining cleaning cycle.
Solution Approach 2:
The cleaning net is designed to be movable rather than stationary, allowing it to be positioned at different locations along the condenser fins. The net can be advanced and repositioned automatically, enabling thorough cleaning of extensive condenser surfaces that would be difficult to reach with fixed manual methods.
2Productivity
If the net moves continuously in one direction, then device complexity is reduced, but cleaning thoroughness deteriorates
Solution Approach 1:
The system alternates the net's movement direction periodically, first moving in one direction to clean one side of the condenser fins, then reversing to move in the opposite direction for cleaning the other side. This periodic bidirectional movement ensures comprehensive cleaning coverage of both surfaces of the condenser fins.
Solution Approach 2:
The cleaning process is divided into separate directional passes, with each pass focusing on cleaning one side of the condenser fins. By segmenting the cleaning task into multiple directional passes rather than attempting to clean all areas simultaneously, the system achieves thorough cleaning without requiring overly complex multi-axis mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the efficiency and longevity of condensers by effectively removing dust and debris, preventing performance degradation and potential breakdown.
Implementation Method 1
The first brush is placed touching the net to brush clean the net when the net moves between the first roller and the second roller
Implementation Method 2
The first brush is placed touching the net to brush clean the net
Implementation Method 3
The net is designed to move between a first roller and a second roller
Implementation Method 4
The net may have a plurality of protrusions, and the first roller and the second roller have sprockets to engage the protrusions of the net
Implementation Method 5
A motor is attached to the first roller to rotate the net around the first roller

AI summary
An automatic condenser cleaner has a net, a first roller, a second roller, and a first brush. The net is placed in front of the condenser to filter an airflow onto the condenser and the net moves between a first roller and a second roller, with the first brush brushing to clean the net while the net moves between the first roller and the second roller.
