Solution Overview
Problem
Prior range hoods suffer from poor fume suction efficiency due to limited air intake area caused by the small spacing between the air deflector and the main body, leading to unsatisfactory fume collection and discharge.
Innovation Solution
A fume collecting assembly with a curved concave fume gathering panel and a curved convex air deflector, forming spaced apart first and second air inlets, which increases the air intake area and enhances fume suction by directing oil fumes into an air duct, along with a skeletal front plate and notch design for improved structural support and oil collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air deflector is positioned close to the main body to achieve compact structure, then the device complexity is reduced, but the air intake area is greatly reduced leading to poor fume suction effect
Solution Approach 1:
The patent transitions from a single-plane air intake structure to a three-dimensional curved surface structure. The air deflector and fume gathering panel are designed with curved convex and concave portions that create multiple air inlets (first air inlet and second air inlet) at different spatial positions, effectively increasing the air intake area without increasing the horizontal footprint of the device.
Solution Approach 2:
The air deflector features a curved convex portion while the fume gathering panel has a curved concave portion. These curved surfaces work together to form air inlets and guide fumes more effectively. The curvature allows the structure to maintain a compact form factor while creating sufficient spacing for air intake channels, resolving the contradiction between compactness and air intake area.
2Productivity
If the spacing between air deflector and main body is increased to improve fume suction, then the air intake area increases, but the device complexity and manufacturing cost increase
Solution Approach 1:
The air deflector and fume gathering panel are designed as integrated components where the curved convex portion of the air deflector and curved concave portion of the fume gathering panel work together to form the air intake structure. This merging of functions allows the structure to achieve increased air intake area and improved fume suction efficiency without requiring additional separate components or complex assembly, thus avoiding increased device complexity.
