Blower Assembly Faceplate Mounting for Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat pump water heater blower assembly enclosures are difficult to disassemble for servicing due to the need to remove the shroud and disconnect fluid or air conduits, limiting access to fan components.
Innovation Solution
The air transferring system includes an enclosure with a base, lid, and shroud, where the blower assembly is attached to a faceplate and positioned externally to the shroud, allowing for easy access and servicing without removing the shroud.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wrap-around sheet-metal shrouds are used to fully enclose the axial fan, then safety requirements are met, but servicing becomes difficult requiring removal of the lid and disconnection of conduits
Solution Approach 1:
The enclosure is segmented into modular components: the shroud remains fixed for safety, while the blower assembly is separated and mounted on a removable faceplate. This allows the faceplate with blower assembly to be detached for servicing without removing the entire shroud, maintaining safety while enabling easy access to fan components.
2Reliability
If the blower assembly is enclosed within the shroud, then safety is maintained, but access to fan components is limited
Solution Approach 1:
The blower assembly is extracted from within the shroud enclosure and remounted on the exterior faceplate. This extraction allows the blower assembly to be accessed and serviced by simply removing the faceplate, while the shroud remains intact to maintain safety enclosure for any remaining internal components.
3Stability of the object's composition
If the blower assembly is positioned inside the enclosure, then structural integrity is maintained, but disassembly complexity increases
Solution Approach 1:
The system is divided into three independent modules: the fixed shroud maintaining structural integrity, the removable faceplate providing access, and the blower assembly mounted on the faceplate. This segmentation allows the faceplate and blower assembly to be detached as a unit for servicing, simplifying disassembly while maintaining the overall structural integrity of the enclosure.
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
This design enables easier disassembly and access to fan components within the enclosure, simplifying maintenance and service operations while maintaining the structural integrity of the enclosure.
Implementation Method 1
an impeller for drawing air through the air exhaust, faceplate opening, and blower exhaust and urging the air out the exhaust

AI summary
An air transferring system is disclosed. The air transferring system includes an enclosure, a faceplate, and a blower assembly attached to the faceplate. The enclosure includes a base, a lid having an air exhaust, and a shroud. The shroud has an open shroud top, an open shroud bottom, and an opening in the shroud defined between a first shroud edge and a second shroud edge. Each of the shroud edges extends between the open shroud top and the shroud bottom. The faceplate includes a faceplate opening that extends between the first and second shroud edges. The blower assembly includes a blower exhaust proximate to all of the faceplate opening, an exhaust opening, and an impeller for drawing air through the air exhaust, faceplate opening, and blower exhaust and urging the air out the exhaust.
