Kitchen Extractor Hood Mounting Frames for Fast Cabinet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for mounting kitchen extractor hoods between hanging cabinets are cumbersome, requiring multiple persons for installation and failing to ensure quick and easy alignment with the cabinets' surface, leading to prolonged installation times.
Innovation Solution
A system comprising a first frame with adjustable projections and a second frame, allowing for secure and accurate positioning of the extraction motor unit and hood casing without the need for screws and bolts, enabling single-person installation and coplanar alignment with hanging cabinets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a first frame is secured to the wall and the hood casing is fixed to the first frame using screws and bolts, then the hood can be securely mounted, but at least two persons are required for installation and the installation time becomes very long
Solution Approach 1:
A second frame is introduced as an intermediary component between the first frame and the hood casing. The second frame includes a holding element that receives the hood casing, eliminating the need for direct screw and bolt fixation between the first frame and casing. This intermediary structure enables single-person installation while maintaining secure mounting.
2Shape
If the hood is installed between two hanging cabinets with coplanar alignment, then aesthetic requirements are met, but the installation becomes more complex and time-consuming
Solution Approach 1:
The second frame is designed with an adjustable projection that can be preliminarily positioned to ensure coplanar alignment with the hanging cabinets before the hood casing is installed. This preliminary adjustment of the frame structure simplifies the overall installation process by pre-establishing the correct positioning and orientation.
3Reliability
If traditional screw and bolt fixation is used to secure the hood casing to the frame, then reliable mounting is achieved, but the installation process becomes cumbersome and requires multiple persons
Solution Approach 1:
The complex screw and bolt fixation process is extracted and replaced by a simplified holding element mechanism. The holding element on the second frame directly receives and secures the hood casing through a plug-socket type connection, eliminating the time-consuming screw and bolt installation while maintaining reliable mounting.

AI summary
The invention relates to a system for mounting a kitchen extractor hood to a vertical wall (1) of a kitchen between a pair of hanging cabinets (2, 3) of the kitchen furniture, which have a given depth (H) relative to the surface (1) of the wall, such system comprising: a hood comprising filter devices (5) for filtering the extracted air, an extraction motor unit (8), a channel for ejecting the extracted air and a casing having an inverted-T shape, wherein the casing comprises a horizontal bar (4) configured to contain the filter devices (5) for filtering the extracted air and a vertical stem (7) configured to contain the extractor motor unit (8) and the channel for ejecting the extracted air; a first frame (9), adapted to be secured to the vertical wall (1) of the kitchen, between the pair of hanging cabinets (2, 3), such first frame (9) having means for supporting the extraction motor unit (8) of the hood and means (18) for adjusting the position of the extraction motor unit (8) relative to the wall (1), based on the depth (H) of the hanging elements; a second frame (19), adapted to be placed and fixed above the first frame (9), such second frame (19) having means (20, 21) for receiving and holding the casing of the hood; wherein the first frame (9) comprises right-angled elements (10, 11), whose vertical long sides are adapted to be fixed to the wall (1) by expansion means (12, 13, 14), such right-angled elements (10, 11) of the first frame (9) comprise overhanging short sides (15, 16), perpendicular to the wall (1) of the kitchen, when the frame is attached thereto, such short sides (15, 16) forming a bracket (17) for positioning and supporting the extraction motor unit (8)
