Combination device with an extractor device and a cooker hob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination devices with integrated extractor hoods face space constraints due to the placement of power electronics and fan housings, limiting installation options and storage space, particularly in standardized kitchens.
Innovation Solution
The power electronics are arranged perpendicular to the cooking modules, allowing for a more compact design that maximizes space below the hob, enabling larger fans and filters without obstructing the air inlet opening, and facilitating easier maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power electronics housing is placed below the cooktop, then the electronics are protected and integrated, but the available space for fan housing is reduced
Solution Approach 1:
The patent changes the orientation of the power electronics housing from a horizontal placement that blocks fan space to a vertical arrangement where the housing extends downward from the cooktop. This dimensional reorientation allows the fan housing to be positioned laterally adjacent to the electronics housing rather than below it, resolving the space conflict while maintaining integration.
2Productivity
If the fan housing size is increased to improve air extraction, then extraction performance is enhanced, but the installation width must be increased beyond standard kitchen dimensions
Solution Approach 1:
The patent transitions from a width-oriented fan housing layout to a depth-oriented configuration. By positioning the fan housing laterally adjacent to the power electronics housing and extending in the depth direction rather than the width direction, the design achieves high extraction performance while maintaining a compact width suitable for standard 60cm kitchen installations.
3Device complexity
If the power electronics are arranged parallel to the cooking modules, then the layout is simplified, but the space below the cooktop is insufficient for both electronics and fan housing
Solution Approach 1:
Instead of arranging the power electronics parallel to the cooking modules (horizontal orientation), the patent inverts the arrangement by positioning the electronics housing vertically below the cooktop. This inversion creates a three-dimensional configuration where the fan housing can be placed laterally adjacent to the electronics housing, efficiently utilizing the available volume below and around the cooktop.
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
This configuration ensures efficient air filtration, reduces noise, and allows for flexible design widths, such as 60cm, while maintaining electromagnetic compatibility and easy access for maintenance.
Implementation Method 1
A fan can be provided in one embodiment. The fan can be arranged in a space laterally adjacent to a recess... the air inlet opening extends through the center of the width of a hob
