Air Conditioner Indoor Unit Chassis Layout to Reduce Horizontal Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioner indoor units face challenges in compact design due to the positioning of the fan motor and control box, which are often obstructed by the pipe unit, making it difficult to install and increasing the overall size of the unit.
Innovation Solution
The indoor unit design includes a chassis with a fan receiving part and a fan motor seating part, allowing the fan motor to be positioned directly adjacent to the fan, and the control box to be seated on a control box seating part, with the pipe unit routed through the rear, minimizing horizontal size and enabling easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fan motor and control box are positioned in the conventional location, then the installation is simpler, but the horizontal size increases and the pipe unit obstructs the components
Solution Approach 1:
The fan motor is repositioned from a conventional horizontal arrangement to a vertical arrangement directly above the fan, utilizing the vertical dimension to reduce horizontal footprint. The control box is moved to the rear side of the chassis, changing its spatial dimension from front-side to rear-side placement. This dimensional reconfiguration eliminates pipe unit obstruction while maintaining installation simplicity.
2Ease of manufacture
If the pipe unit is routed through the front, then the connection is easier, but it obstructs the fan motor and control box positioning
Solution Approach 1:
The control box is extracted from its conventional position near the front and relocated to the rear side of the chassis, separating it from the pipe unit routing path. This extraction eliminates the obstruction conflict between the pipe unit and control box, allowing the pipe unit to be routed through the front for easy connection while the control box occupies the rear space without interference.
3Ease of manufacture
If the fan motor is positioned away from the fan, then the pipe unit can be routed, but the distance increases and space utilization decreases
Solution Approach 1:
The fan motor is repositioned to the vertical dimension directly above the fan, utilizing the vertical space above the fan assembly. This vertical placement allows the pipe unit to be routed horizontally through the front without obstruction, while the fan motor remains in close proximity to the fan through vertical alignment, maintaining compact space utilization.
