Detachable Fan Base Structure for Easy Indoor AC Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing indoor units for air conditioners are inconvenient for users to disassemble and clean the fan wheel due to its integration with the heat exchanger and base plate, requiring professional help and resulting in high costs.
Innovation Solution
The design includes a guide assembly with a guide groove and rail system that facilitates easy mounting and dismounting of the lower base plate, allowing for independent disassembly and cleaning of the fan without affecting the heat exchanger, and incorporates a detachable structure for the fan and heat exchanger to simplify maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fan wheel is integrated with the heat exchanger and base plate, then the structural stability is improved, but the ease of disassembly and cleaning deteriorates
Solution Approach 1:
The housing is divided into an upper base plate and a lower base plate that can be detachably separated. The fan wheel is mounted on the lower base plate, which can be removed independently from the upper base plate containing the heat exchanger. This segmentation allows the fan wheel to be accessed and cleaned without removing the heat exchanger, resolving the contradiction between structural stability and ease of disassembly.
2Strength
If the fan wheel is limited by the heat exchanger and base plate, then the structural integrity is improved, but the ease of repair deteriorates
Solution Approach 1:
The detachable connection between the upper base plate and lower base plate enables independent access to the fan wheel for cleaning and maintenance while preserving the overall structural integrity when assembled. The lower base plate can be removed separately to service the fan wheel without affecting the heat exchanger or compromising structural strength.
3Reliability
If professional help is required for fan wheel cleaning, then the reliability of maintenance is improved, but the cost increases
Solution Approach 1:
The detachable lower base plate design enables users to independently remove and clean the fan wheel without requiring professional service. Users can access the fan wheel by simply removing the lower base plate from the upper base plate, perform cleaning themselves, and reassemble the unit, thereby reducing maintenance costs while maintaining reliability through regular user-performed cleaning.
