3D Cooking Chamber Floor Foil Heater for Condensate Evaporation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking appliances with external steam generators face inefficiencies in heating the cooking chamber floor, leading to incomplete evaporation of condensate and potential overheating due to limited heated areas and uneven water distribution, especially when the appliance is tilted.
Innovation Solution
A cooking appliance with a foil heating element that has a three-dimensional shape matching the cooking chamber floor, equipped with temperature sensors and safety devices to ensure effective evaporation and prevent overheating by switching off the heating element when the water level drops below a certain threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a foil heating element is arranged on the outside of the cooking chamber floor to heat the floor, then an evaporation surface is provided inside the cooking chamber, but only a limited area of the cooking chamber floor can be heated
Solution Approach 1:
The foil heating element is formed in a three-dimensional shape that protrudes into the cooking chamber, transforming a two-dimensional heating surface into a three-dimensional structure. This allows the heating element to heat both the bottom and side surfaces of the cooking chamber floor simultaneously, effectively increasing the heated area without expanding the horizontal footprint of the element.
2Ease of operation
If the cooking appliance is set up at a slight angle, then condensate may not collect in the area of the film heating element, but the foil heater may overheat due to insufficient water coverage
Solution Approach 1:
By forming the foil heating element in a three-dimensional shape that protrudes into the cooking chamber, the element creates a deeper water collection area that is less sensitive to appliance tilting. The three-dimensional structure ensures that condensate can still effectively cover the heating element even when the appliance is installed at an angle, preventing overheating while maintaining installation flexibility.
Solution Approach 2:
The three-dimensional shape of the foil heating element anticipates potential tilting issues by creating a deeper water collection area in advance. This design cushioning ensures that even if condensate distribution is uneven due to tilting, there is sufficient water depth to prevent the heating element from overheating.
3Productivity
If a foil heating element is used to heat the cooking chamber floor, then condensate can be evaporated, but the heating element may overheat when not completely covered by condensate
Solution Approach 1:
The three-dimensional shape of the foil heating element creates a deeper water collection area that holds more condensate, ensuring the heating element remains covered by water during evaporation. This maintains high evaporation capability while reducing overheating risk through increased water retention.
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
The solution provides a larger, more effective evaporation surface by heating both the bottom and side surfaces of the cooking chamber floor, ensuring safe operation by preventing overheating through precise temperature control and water level detection.
Implementation Method 1
At least one foil heating element is arranged on the outside of the cooking chamber floor, which element is suitable and designed to heat the cooking chamber floor at least in sections
Implementation Method 2
During the cooking process, steam condenses on the food and the walls of the food and collects on the floor of the cooking space. There, this condensate can then advantageously be evaporated again
