Air Cleaner Flow Adjusting Device with Gear-Driven Directional Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaners are limited in their ability to discharge filtered air in a horizontal direction parallel to the top surface of the blower, and the space within the blower restricts the orientation of the flow adjusting device, making it difficult to direct air in desired directions.
Innovation Solution
An air cleaner with a blower, flow adjusting device, and guide member that includes a plurality of gears allowing the flow adjusting device to change orientation from horizontal to perpendicular to the blower surface, facilitated by a housing and guide gear assembly that controls the flow adjusting device's position and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flow adjusting device is added to change air discharge direction, then air can be blown in directions other than vertical, but the operating radius is limited and horizontal direction discharge is not achieved
Solution Approach 1:
The flow adjusting device is made rotatable through the guide member with gear mechanisms, allowing dynamic adjustment of the discharge direction from vertical to horizontal positions. The rotation mechanism enables the device to change its orientation freely rather than being fixed at limited angles.
Solution Approach 2:
The guide member extends the operating radius by utilizing the vertical space dimension within the blower housing. The gear mechanisms are arranged to rotate the flow adjusting device around a horizontal axis, adding a rotational degree of freedom that expands the achievable discharge directions into the horizontal plane.
2Adaptability or versatility
If a rotation guide is added to induce rotation of the flow adjusting device, then air can be blown in different directions, but the limited space inside the blower restricts the length of the rotation guide
Solution Approach 1:
The gear mechanisms of the rotation guide are nested within the existing blower housing structure. The guide member and its rotational components are positioned to utilize the available vertical space efficiently, with gears arranged in a compact configuration that fits within the blower's internal volume.
Solution Approach 2:
The rotation guide employs a compact gear mechanism that achieves full rotational functionality within a limited space. The gear train is designed to rotate the flow adjusting device through a complete 90-degree range from vertical to horizontal discharge positions without requiring excessive linear space.
3Adaptability or versatility
If the flow adjusting device is positioned to discharge air horizontally, then desired horizontal discharge is achieved, but the device complexity increases
Solution Approach 1:
The guide member serves multiple functions: it guides the rotation of the flow adjusting device, provides structural support, and houses the gear mechanisms. The gear train simultaneously transmits rotational motion and defines the angular positions for both vertical and horizontal discharge orientations.
Solution Approach 2:
The flow adjusting device is merged with the guide member structure, where the device is rotatably coupled to the guide member rather than being a separate fixed component. This integration allows the combination to function as a unified adjustable discharge system.

AI summary
Disclosed is an air cleaner, more specifically, an air cleaner including a blower that inhales air from the outside, filters the inhaled air, and discharges the filtered air, a flow adjusting device disposed on the blower to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air, and discharge the air, and a guide member disposed below the flow adjusting device to change a state of the flow adjusting device. The guide member may include a plurality of gears arranged inside the guide member to be rotatable, some of the plurality of gears may be connected to each other to be rotatable in engagement with each other, and the flow adjusting device may change the discharge direction of the air by rotations of the plurality of gears of the guide member.
