Central Suction Hob Layout for Efficient Cooking Vapor Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hobs with suction slits on both sides and back are inefficient due to canceled suction flows, high manufacturing and maintenance costs, and noise generation, as they restrict countertop usage and fail to effectively remove cooking vapors from the central area.
Innovation Solution
A hob design with recesses only around its geometric center, featuring a device for downward suction of cooking vapors, allowing unrestricted countertop usage, reduced manufacturing and maintenance costs, and efficient energy use, with a compact assembly unit that eliminates the need for a separate mounting frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If suction slits are provided on both sides and on the back of the hob, then cooking vapors can be removed through suction, but the suction flows cancel each other out in the central area, allowing vapors to rise unimpeded
Solution Approach 1:
The invention extracts the suction function from the peripheral slits and concentrates it in the central area. The suction device is positioned directly below the geometric center of the hob, creating a focused suction flow that effectively captures cooking vapors at their source without the cancellation effect of opposing flows.
Solution Approach 2:
The invention transitions from horizontal peripheral suction to vertical central suction. By positioning the suction device below the hob and directing airflow vertically upward through the central area, the system creates a three-dimensional suction pattern that efficiently captures vapors rising from the cooking surface.
2Object-generated harmful factors
If suction slits are provided on both sides and on the back of the hob, then cooking vapors can be removed, but the countertop surfaces cannot be completely used for temporary storage
Solution Approach 1:
The invention removes the peripheral suction slits from the hob design, extracting the suction function and relocating it to the central area. This eliminates the need for side and back slits, freeing up the entire countertop surface for storage and other purposes.
3Object-generated harmful factors
If three suction devices with three grease filters are used, then cooking vapors can be removed from all areas, but manufacturing, assembly, and maintenance costs increase
Solution Approach 1:
The invention merges the three separate suction devices and their associated grease filters into a single centralized suction system. This consolidation reduces the number of components from three to one, simplifying manufacturing, assembly, and maintenance while maintaining effective vapor removal through the optimized central positioning.
Solution Approach 2:
The single central suction device performs the function previously distributed across three devices, serving as a universal solution that handles vapor removal from all cooking areas on the hob through its centrally located, powerful suction capability.
4Object-generated harmful factors
If strong suction flows are released through all suction slits simultaneously, then cooking vapors can be removed, but energy expenditure and noise generation increase
Solution Approach 1:
The invention extracts the suction function from multiple peripheral locations and concentrates it in a single central position. This allows the suction system to operate more efficiently with lower energy consumption, as the centralized design creates a more effective airflow pattern that captures vapors with less power requirement.
Solution Approach 2:
The invention changes the operational parameters of the suction system by transitioning from multiple high-power peripheral slits to a single optimized central suction point. This parameter change results in reduced energy expenditure and lower noise generation while maintaining or improving vapor removal effectiveness.
