Kitchen appliance with cupboard and combination device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen appliances with integrated extractor devices require complex dismantling of furniture parts to replace odor filters, making the process cumbersome and inconvenient.
Innovation Solution
The odor filter is positioned in the front area of the combination device, allowing easy access by removing a cover plate, and is held in a movable filter holder for simple removal and replacement, reducing the need for extensive disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the odor filter is positioned at the rear end of the kitchen cabinet extending vertically downwards into the air duct, then a large-capacity filter can be used, but a large number of furniture components must be dismantled to replace the filter
Solution Approach 1:
The patent repositions the odor filter from a vertical rear-end location to a horizontal front-end location within the combination device. This dimensional change allows the filter to be accessed from the front of the kitchen cabinet rather than requiring dismantling of rear furniture components, thereby simplifying replacement while maintaining adequate filter capacity through optimized placement in the air duct's front section
2Ease of operation
If the odor filter is positioned in the middle of the air duct height, then filter replacement is simplified, but the filter holder requires complex mounting structures
Solution Approach 1:
The patent segments the combination device into distinct functional modules: the odor filter is separated as an independent removable component housed in a dedicated filter holder that is itself separable from the main device body. This segmentation allows the filter to be accessed and replaced independently without complex mounting structures, as the filter holder can be简单地 removed from the front to provide direct access to the filter
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 design simplifies the handling and maintenance of odor filters by allowing straightforward access and replacement without disassembling multiple furniture components, enhancing user convenience and reducing installation complexity.
Implementation Method 1
These filters are arranged in an air duct connected to an extractor hood housing and extend vertically downwards at the rear end of a kitchen cabinet into which the cooktop and extractor hood are installed. Such a cooktop with integrated extractor hood is described, for example, in WO 2018/036800 A1.
Implementation Method 2
An odor filter is a filter for filtering out odorous substances. In particular, the odor filter can be an activated carbon filter.
