Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hob devices with integrated extractor units require additional cooling fans, increasing complexity and costs, while existing solutions do not efficiently address the need for low complexity and effective cooling of hob units.
Innovation Solution
A hob device with an integrated extractor unit that uses a blower unit to generate two air flows: one for vapor extraction and another for cooling the hob unit, eliminating the need for an additional cooling fan by utilizing an air duct unit with cooling ribs and an optimized air flow direction to efficiently cool the hob unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an additional cooling fan is used to cool the hob unit, then the cooling effectiveness is improved, but the device complexity and costs increase
Solution Approach 1:
The blower unit is designed to perform multiple functions: it generates both the first air flow for vapor extraction and the second air flow for cooling the hob unit. This multi-functionality eliminates the need for a separate cooling fan, reducing device complexity while maintaining effective cooling through the integrated design.
2Reliability
If multiple separate units are used for vapor extraction and cooling, then each function can be optimized independently, but the overall device complexity increases
Solution Approach 1:
The patent combines the vapor extraction function and the cooling function into a single integrated system using one blower unit. The air duct is designed with multiple outlets that distribute air flows for both vapor removal and hob unit cooling, achieving functional integration while maintaining reliable performance through careful airflow path design.

AI summary
The invention is based on a hob device (10a-c) with at least one hob plate (12a-c) and with at least one integrated extraction unit (14a-c) which has at least one blower unit (16a-c) which, in at least one operating state, is at least generates a first air flow (18a-c) and uses the first air flow (18a-c) to transport away vapors arising in the operating state. In order to provide a generic device with improved properties in terms of low complexity, it is proposed that the blower unit (16a-c) generates at least one second air flow (20a-c) in the operating state and is intended to be at least partially ventilated by means of the second air flow (20a -c) to cool at least one hob unit (22a-c).
