Indoor unit of air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner indoor units require users to remove large components for cleaning, which is difficult and poses a risk of refrigerant leakage, and does not allow for easy access to the blower fan for cleaning without exposing the user to rotating parts and potential dew formation.
Innovation Solution
The indoor unit design includes a display panel that can be hinged and positioned to expose the lower cabinet portion for cleaning, with a cover that can be removed to stop the blower fan and allow access through a bottom outlet, featuring a hanger system for secure placement and a control vane to prevent dew formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front panel, heat exchanger, and orifice are removed to clean the blower fan, then the blower fan becomes accessible for cleaning, but the cleaning process becomes difficult and complex, and there is a risk of refrigerant leakage
Solution Approach 1:
The cabinet is divided into multiple removable covers (front cover, side covers, rear cover) that can be selectively removed. The blower fan is accessed by removing only the necessary covers rather than the entire front panel and heat exchanger assembly, simplifying the cleaning process while maintaining system integrity
Solution Approach 2:
The blower fan is extracted from the cabinet structure by providing dedicated access paths through removable covers. This allows the blower fan to be accessed and cleaned independently without removing the heat exchanger or orifice, reducing the number of components that need to be handled
2Ease of operation
If the blower fan is exposed for cleaning, then the fan becomes accessible, but the user may be injured by the rotating blower fan
Solution Approach 1:
The control unit is programmed to automatically stop the blower fan before the cover is fully removed or during the cleaning process. This preliminary action of stopping the fan eliminates the rotating blade hazard while maintaining accessibility for cleaning operations
Solution Approach 2:
The control unit monitors the state of the cover (attached or removed) and provides feedback control to the blower fan operation. When the cover is removed, the system detects this state and automatically stops the fan to prevent injury, while allowing the fan to operate normally when the cover is attached
3Adaptability or versatility
If the display panel is fixed in one position, then the structure is simple, but the display panel cannot be positioned differently for cleaning access and operation
Solution Approach 1:
The display panel is transformed from a fixed structure to a dynamic one that can change positions. The hanger and connecting link mechanism allows the display panel to move between a first position (for normal operation) and a second position (for cleaning access), providing adaptability while maintaining structural integrity through controlled movement
