Tower Blower Layout for Concentrated Airflow and Heater Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers, such as axial fans, struggle to provide intense or concentrated air flow in narrow regions and often lack the space to accommodate heaters for air heating, while existing fan designs with displays can interfere with air flow and are not conveniently integrated.
Innovation Solution
The design incorporates a blower with a unique configuration of towers and airflow converters that utilize the Coanda effect to enhance air flow concentration and integration of a heater, while a display module is positioned to minimize interference with airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an axial fan is used to provide wide air flow coverage, then the air flow covers a wide range, but the air flow is not concentrated or intense in narrow regions
Solution Approach 1:
The blower is divided into multiple towers (first tower, second tower, third tower) with separate air discharge ports, allowing different regions to serve different functions. The first and second towers provide wide coverage while the third tower provides concentrated airflow in a specific direction.
Solution Approach 2:
Different towers are designed with different characteristics to provide localized air flow qualities. The airflow converters in specific towers create concentrated airflow in narrow regions, while other towers maintain wide coverage, allowing each part to have optimized local properties.
2Length of stationary object
If the air discharge port is positioned close to the fan, then the air flow path is compact, but there is insufficient space to accommodate a heater for air heating
Solution Approach 1:
The blower utilizes vertical stacking of multiple towers to extend the air flow path in the vertical dimension rather than horizontally. This allows the air flow path to be sufficiently long for heater accommodation while maintaining a compact horizontal footprint.
Solution Approach 2:
The heater is integrated within the air flow path structure itself, with the air flow path accommodating the heater as a nested component. The air flow path is designed to wrap around or contain the heater, allowing compact integration rather than separate positioning.
3Adaptability or versatility
If a display is integrated into the fan structure, then information display is provided, but the display interferes with the air flow
Solution Approach 1:
The display is extracted from the main air flow path structure and positioned in a separate location (front surface of the case) where it does not interfere with air flow. The display function is separated from the air moving function to eliminate interference.
Solution Approach 2:
The controller serves as an intermediary that manages both the display and air flow converter operations. It receives user input and coordinates the air flow converters and display separately, allowing independent optimization of each function without direct physical interference.
4Area of stationary object
If multiple air discharge ports are provided in different directions, then air flow coverage is enhanced, but the device structure becomes more complex
Solution Approach 1:
Multiple towers with different air discharge ports are designed to work together as a unified system controlled by a single controller. Each tower can operate independently or in coordination, providing multi-directional air flow coverage while being managed as an integrated device rather than separate units.

AI summary
A blower may include a first case and a second case provided above the first case and having a first tower and a second tower that have a passage therebetween. A display assembly is received in the second case at a position that does not interfere with air flowing in the passage. An inner surface of the second tower and an outer surface of a diffuser define a space in which the display assembly is received.
