Solution Overview
Problem
Existing ceiling type air purifiers require complex and cumbersome processes to access the electric components, leading to increased overall volume and difficulty in maintenance.
Innovation Solution
A ceiling type air purifier design with a housing that includes a convergent space containing the electric room, a discharge assembly that rotates to open the convergent space for access, and a flow path for air circulation, allowing easy access to internal components without disassembling the entire unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the discharge assembly is made detachable and rotatable, then accessibility to electric components is improved, but device complexity increases
Solution Approach 1:
The discharge assembly is segmented into a discharge plate and a discharge blade that can rotate independently on the rotation shaft. This segmentation allows the discharge blade to be accessed and removed separately while the discharge plate remains attached to the housing, enabling electric component maintenance without complete disassembly.
Solution Approach 2:
The discharge blade is designed to rotate dynamically on the rotation shaft rather than being fixed. This dynamic configuration allows the blade to be rotated to an accessible position for maintenance while maintaining its functional position during operation, resolving the contradiction between accessibility and structural integrity.
2Loss of time
If the convergent space is made accessible through the discharge assembly, then maintenance time is reduced, but the discharge assembly structure becomes more complex
Solution Approach 1:
The discharge blade is extracted as a separate removable component from the discharge assembly. This extraction allows the blade to be quickly removed and replaced without affecting other components, significantly reducing maintenance time while keeping the overall structure relatively simple.
Solution Approach 2:
The discharge assembly serves multiple functions: it controls air discharge direction during normal operation and provides access to the convergent space during maintenance. This multi-functionality reduces the need for separate access mechanisms, minimizing structural complexity while enabling quick maintenance access.
3Adaptability or versatility
If the discharge blade is rotatable on the discharge plate, then air discharge direction control is improved, but manufacturing complexity increases
Solution Approach 1:
The rotation shaft is merged with the discharge plate structure, forming an integrated assembly. This merging simplifies manufacturing by reducing the number of separate parts and assembly steps while still enabling the discharge blade to rotate for directional control of air discharge.
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
Enhances accessibility to electric components, reduces the overall volume of the air purifier, and simplifies maintenance by enabling access through a rotational operation of the discharge assembly.
Implementation Method 1
a fan configured to circulate air having passed through the filter
Implementation Method 2
a discharge blade rotatably coupled with the discharge plate so as to be rotatable to control a moving direction of air discharged from the convergent space
Implementation Method 3
The discharge assembly may be coupled with the housing to be rotatable on the rotation shaft so as to rotate to open the convergent space to allow access to the convergent space

AI summary
A ceiling type air purifier including a housing having an opening on a lower side; a filter on one side of the opening and fixed to the housing; a fan configured to circulate air having passed through the filter; a convergent space formed in the housing and configured to receive air circulated by the fan; and a discharge assembly including a discharge plate formed to match a lower portion of the convergent space, a discharge blade rotatably coupled with the discharge plate so as to be rotatable to control a moving direction of air discharged from the convergent space, and a rotation shaft at one end of the discharge assembly. The discharge assembly may be coupled with the housing to be rotatable on the rotation shaft so as to rotate to open the convergent space to allow access to the convergent space, and to rotate to close the convergent space.
