Drain Pan Access Panel for Air Conditioner Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners require onerous work for visual examination of the drain pan due to dirt accumulation on transparent inspection windows and necessitate detachment of the drain pan for water quality checks, which is labor-intensive.
Innovation Solution
An air conditioner design featuring a maintenance panel with a detachable lid member that allows visual examination of the drain pan and suction port without tools, enabling tool-free attachment and detachment for simplified water quality checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transparent inspection window is provided to the drain pan, then visual examination of the drain pan becomes possible, but dirt accumulation on the transparent plate member makes examination difficult
Solution Approach 1:
The invention extracts the examination function from the transparent inspection window by providing a separate opening part in the casing that allows direct visual access to the drain pan. This bypasses the transparent plate member that accumulates dirt, enabling reliable examination without being affected by dirt on the original inspection window.
Solution Approach 2:
The opening part in the casing serves as an intermediary access point that provides a clear line of sight to the drain pan. This intermediary structure allows examination without requiring the transparent plate member to remain clean, as the opening provides direct visual access around or beyond the inspection window area.
2Measurement precision
If the drain pan is detached for water quality examination, then thorough inspection is possible, but the work becomes onerous and labor-intensive
Solution Approach 1:
The invention extracts only the necessary examination capability from the drain pan assembly by providing an opening part in the casing. This allows users to perform water quality examinations without detaching the entire drain pan, extracting only the visual access function while leaving the drain pan installed and functional.
Solution Approach 2:
The examination function is segmented from the drain pan detachment operation. The opening part in the casing provides a dedicated access path that separates the examination activity from the drain pan removal process, allowing independent access for inspection without affecting the drain pan's installation or requiring full disassembly.
3Ease of operation
If the opening part is provided in the casing, then visual examination without detachment is possible, but the opening may affect the structural integrity or aesthetics
Solution Approach 1:
The opening part in the casing serves multiple functions: it provides visual access to the drain pan for examination, allows natural light to illuminate the examination area, and can be integrated with the existing casing structure without requiring separate complex mechanisms. This multi-functionality reduces the need for additional components.
Solution Approach 2:
The opening part is strategically positioned and sized to provide sufficient examination access while minimizing impact on the overall casing structure. The opening can be located in areas where structural impact is minimal, and its size is optimized to provide adequate viewability without creating large structural weaknesses or aesthetic compromises.

AI summary
In order to enable a drain pan to be visually checked for contamination without requiring a complicated operation, the present invention is configured so as to be equipped with: a housing; a drain pan provided inside the housing; a drain pump for pumping up drain water accumulated in the drain pan; an opening provided in a side surface of the housing; and a cover member attached to the opening and covering the opening. When the cover member is detached from the opening at least a portion of the drain pan can be viewed from the opening.
