Humidifying Air Purifier Drawer Layout for Easy Filter Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing humidifying air purifiers face challenges such as difficult access to internal components, compromised air intake performance due to narrow spaces, and issues with water leakage affecting filter and blower performance.
Innovation Solution
A humidifying air purifier design featuring a drawer-type door assembly that allows easy access to internal components, with a water container and filter positioned on the door, improved air intake from the lower front, and an air filter on the back surface for enhanced filtration, along with a guide structure for mounting the air filter and a centrifugal fan secured within the cabinet for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air blower, air purifying filter, and humidifying unit are stacked vertically from lower to upper portion, then the device structure is compact, but it becomes troublesome and difficult to separate and access the air purifying filter or humidifying unit for cleaning or replacement
Solution Approach 1:
The device is divided into three separate horizontal drawers: the air blower in the lower drawer, the air purifying filter in the middle drawer, and the humidifying unit in the upper drawer. This segmentation allows each component to be independently accessed and removed without affecting the others, solving the problem of difficult separation and access while maintaining a compact vertical arrangement.
2Adaptability or versatility
If the inlet is formed on the rear surface or bottom surface of the main body, then the air purifier can be disposed adjacent to wall surface, but the space between the main body and wall surface or bottom surface is too narrow, deteriorating the intake performance
Solution Approach 1:
The air inlet is positioned on the front surface of the device rather than the rear or bottom surface. This dimensional change in inlet placement allows sufficient space for air intake even when the device is placed close to a wall, maintaining good intake performance while preserving adaptability to various placement locations.
3Device complexity
If the filter and driving fan are installed together in the inner space of the drawer, then the structure is simplified, but when the user draws out the drawer to replace or clean the filter, a relatively heavy driving fan has to be also drawn out together
Solution Approach 1:
The air blower (driving fan) is separated from the air purifying filter and placed in a different drawer. The filter is located in the middle drawer while the blower is in the lower drawer. This segmentation allows users to remove and service the filter without having to handle the heavy blower, reducing the weight of movable components during maintenance operations.
4Device complexity
If the humidifying unit is disposed above the air blower and air purifying filter, then the vertical stacking is achieved, but water present in the humidifying unit can be dropped and flow into the blower or air purifying filter, deteriorating performance or causing failure
Solution Approach 1:
The humidifying unit is placed in the upper drawer, separated from the air blower and air purifying filter which are in lower drawers. This vertical segmentation with horizontal separation prevents water from the humidifying unit from flowing into the blower or filter, even if leakage occurs, thereby maintaining reliability while preserving the compact vertical structure.

AI summary
A humidifying air purifier includes a door assembly supported and configured to be selectively drawn out of a front side of a cabinet and drawn into the front side of the cabinet to respectively open and close an inner portion of the cabinet. The door assembly includes an accommodation portion configured to support an air filter and a humidifying device which are both drawn out of and into the humidifying air purifier with the door assembly.
