Removable Motor Fan Assembly in Combustion Blower Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blower designs for furnaces in smaller buildings and mobile homes complicate maintenance and servicing due to fixedly attached motor and fan assemblies, which can hinder airflow and require complex disassembly for maintenance.
Innovation Solution
A blower housing with a removably attached cover that captures the motor and fan assembly between housing and cover portions, allowing for easy access and removal without additional fasteners or brackets, facilitating maintenance and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the motor and fan assembly is fixedly attached to the blower housing with separate brackets, then the assembly is securely mounted, but maintenance and servicing become complicated
Solution Approach 1:
The motor and fan assembly is integrated directly into the blower housing structure, eliminating the need for separate mounting brackets. The assembly is captured between the housing body and housing cover, creating a unified structure that simplifies maintenance while maintaining secure mounting.
2Ease of operation
If the motor and fan assembly is fixedly attached directly to the housing cover, then the assembly is securely mounted, but disassembly requires complex procedures
Solution Approach 1:
The blower housing is segmented into a housing body and a removable housing cover. The motor and fan assembly is positioned between these two segments, allowing the cover to be removed for easy access to the assembly without complex disassembly procedures, while maintaining secure mounting when assembled.

AI summary
A combustion air supply blower includes a blower housing having a housing body and housing cover. The cover is removably attached to the housing body and generally provides access to a motor and fan assembly including a fan and a motor. The motor and fan assembly is removably mounted within the housing body and is captured between the housing body and the housing cover such that, upon removal of the housing cover, the motor and fan assembly is exposed and may then be lifted out of the housing body for easy maintenance, repair, and/or replacement of any portion of the motor and fan assembly. Alternatively, upon removal of the housing cover, the motor and fan assembly may be accessed while remaining within the housing body to complete any maintenance and/or repair of the motor and fan assembly.
