Convex Cyclone Body Shape for Lower Vacuum Cleaner Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone dust-separating apparatuses in vacuum cleaners face issues with increased operating noise and pressure loss due to uniform cylinder shape, leading to higher power consumption and frequent emptying of dust collections.
Innovation Solution
The cyclone dust-separating apparatus features a cyclone body with a convex cylinder shape, where the diameter is maximized at the air discharging part, and can be formed by joining convex and linear cylinder portions, with various inlet shapes to reduce airflow speed and pressure loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cyclone body is formed in a uniform cylinder shape, then the manufacturing is simple, but the air flowing speed increases at the air discharging part causing increased pressure loss and operating noise
Solution Approach 1:
The cyclone body is designed with non-uniform diameter along its longitudinal axis, where the diameter varies to control airflow characteristics. Specifically, the diameter is smaller near the air discharging part to reduce airflow speed and pressure loss, while maintaining sufficient diameter in other sections for effective dust separation. This local variation in geometric property resolves the contradiction between manufacturing simplicity and energy loss.
Solution Approach 2:
The patent changes the geometric parameter (diameter) of the cyclone body along its length to optimize performance. By making the diameter variable rather than constant, the airflow speed at the discharging part is controlled, reducing pressure loss and operating noise while maintaining dust separation efficiency.
2Ease of manufacture
If the cyclone body is formed in a uniform cylinder shape, then the manufacturing is simple, but the operating noise increases due to increased airflow speed at discharge
Solution Approach 1:
The cyclone body employs local quality variation by having different diameters at different sections. The diameter is specifically reduced near the air discharging part to lower airflow velocity, which directly reduces turbulence and operating noise, while maintaining adequate diameter elsewhere for proper cyclone function.
Solution Approach 2:
By changing the diameter parameter along the longitudinal axis of the cyclone body, the patent controls the airflow characteristics to minimize noise generation. The variable diameter design reduces sudden expansions and contractions that cause turbulence and noise, achieving quieter operation.
3Ease of manufacture
If the cyclone body is formed in a uniform cylinder shape, then the manufacturing is simple, but the suction motor output must be increased to compensate for pressure loss
Solution Approach 1:
The non-uniform diameter design with smaller diameter near the discharge part creates a more efficient airflow path that reduces pressure loss. This allows the suction motor to operate at lower power output while maintaining the same dust separation performance, reducing energy consumption.
Solution Approach 2:
By optimizing the diameter parameter distribution along the cyclone body, the patent reduces overall pressure loss in the system. This parameter optimization enables the suction motor to deliver the required performance with lower power consumption, improving overall system efficiency.
