Extractor hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor hoods with edge extraction filters face difficulties in cleaning the collection device separately from the baffle plate, and the collection channel must be removed for cleaning, which is inconvenient and limits its size.
Innovation Solution
An extractor hood design with a detachable collection container that rests on the inside of the baffle plate, allowing for easy removal and cleaning by hand or in a dishwasher, and an inclined inner frame to guide liquid droplets into the collection container, preventing them from escaping through edge gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a baffle plate with collection channel is integrated into the extractor hood, then liquid contaminants are effectively collected, but the collection device cannot be cleaned separately from the baffle plate
Solution Approach 1:
The collection channel is segmented from the baffle plate by providing a detachable connection. The collection channel can be separated from the baffle plate, allowing independent cleaning of each component. This segmentation resolves the contradiction by maintaining the collection function while enabling separate cleaning operations.
Solution Approach 2:
The collection channel is extracted as a separate removable component from the baffle plate assembly. This extraction allows the collection channel to be detached for cleaning purposes while the baffle plate remains in place, solving the cleaning convenience issue without compromising the liquid collection efficiency.
2Device complexity
If the collection channel is integrated into the baffle plate, then the structure is simplified, but the collection channel must be removed from the cooker hood for cleaning
Solution Approach 1:
The collection channel is segmented as a detachable component that can be easily separated from the baffle plate. This segmentation maintains relative structural simplicity while enabling quick removal and cleaning, reducing the time loss associated with cleaning operations.
3Productivity
If narrow gaps are used in the intake area for perimeter extraction, then extraction efficiency is improved, but grease and water droplets separate and soil the inner frame
Solution Approach 1:
The collection channel is extracted as a separate component specifically designed to collect and remove liquid contaminants (grease and water droplets) before they can soil the inner frame. This extraction of the collection function into a dedicated removable component solves the harmful deposition issue while maintaining narrow gap extraction efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy cleaning of the extractor hood by allowing the collection container to be detached and cleaned independently, while the inclined frame ensures efficient collection of liquid droplets, preventing them from falling outside the device.

AI summary
The invention relates to extractor hoods with edge extraction. Here, the cooking vapors are usually sucked in via a gap formed between a baffle plate and the extractor housing. Due to the flow deflection required for edge extraction, fat and water droplets from the cooking vapors sucked in are separated in the inner frame of the device and soil it. A collection container on the inside of the baffle plate, in which the fat and water drops are collected, is suggested.
