Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioner designs with integrated heat exchangers, fans, and dust removal devices complicate the attachment and detachment of dust removal mechanisms, limiting the versatility and ease of maintenance of indoor units.
Innovation Solution
A modular cleaning unit with a chamber casing connected to the indoor main unit, featuring an air filter and a dust removal device that can be easily mounted and detached, along with a dust collecting device and transfer mechanism, utilizing the indoor fan's airflow for efficient dust collection and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the dust removal device is integrated with the heat exchanger and indoor fan in a single casing, then the dust removal function is provided, but the attachment and detachment of the dust removal device becomes complicated and the versatility of the indoor unit is limited
Solution Approach 1:
The dust removal device is separated from the indoor main unit into an independent cleaning unit that can be attached to or detached from the indoor unit. This segmentation allows the dust removal function to be added or removed based on user needs, thereby improving versatility while reducing structural complexity when the dust removal function is not required.
Solution Approach 2:
The indoor unit is designed with a universal structure that can operate both with and without the cleaning unit attached. The chamber casing is connected to the room side of the indoor main unit in a manner that allows easy attachment and detachment, making the indoor unit versatile enough to serve different user requirements.
2Ease of operation
If the dust removal device is integrated with the heat exchanger and indoor fan, then the dust removal function is provided, but the ease of attachment and detachment of the dust removal device is reduced
Solution Approach 1:
By dividing the system into a main indoor unit and a separate cleaning unit with chamber casing, the patent enables independent attachment and detachment of the dust removal function. This segmentation makes the attachment and detachment operations simple and easy, without requiring complex integration procedures.
3Quantity of substance
If the dust collecting device is provided outside the cleaning unit, then the dust collection capacity is increased, but the overall structure becomes less compact and installation work is increased
Solution Approach 1:
The dust collecting device is merged with the cleaning unit by positioning it within the chamber casing. This integration maintains compactness of the overall structure while providing sufficient dust collection capacity. The dust collecting device occupies space within the existing chamber casing, eliminating the need for additional external components and reducing installation complexity.
