Cooking Chamber Coating Structure for Easier Pollutant Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cookers with enamel coating layers face difficulties in easily removing pollutants adhered to the inner surfaces during the cooking process, as these pollutants are strongly chemically bonded, making cleaning inefficient.
Innovation Solution
A cooker design featuring a first ceramic-based coating layer and a second layer with a higher percentage of hydrophilic phosphorus oxide-based components, which absorbs pollutants through weaker Van der Waals interactions, allowing for easier removal with polar solvents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an enamel coating layer is provided on the inner surface of the cooking chamber, then the inner surface is protected from heat and impact, but pollutants adhere strongly to the coating layer and are difficult to remove
Solution Approach 1:
The coating layer is divided into two distinct layers: a lower enamel coating layer (first coating layer) that provides heat and impact protection, and an upper hydrophilic coating layer (second coating layer) that facilitates easy cleaning. This segmentation allows each layer to perform its specific function independently, resolving the contradiction between protection and ease of cleaning.
Solution Approach 2:
The invention uses a composite coating structure combining enamel material in the first layer with hydrophilic material (containing phosphorus oxide-based components) in the second layer. This composite material approach enables the coating system to simultaneously achieve thermal protection, impact resistance, and pollutant release functionality.
2Ease of manufacture
If a single enamel coating layer is used, then the manufacturing process is simple, but the bonding strength between pollutants and the coating surface is too strong for efficient cleaning
Solution Approach 1:
The single coating layer is segmented into two functional layers with different properties. The first layer maintains the traditional enamel composition for protection, while the second layer introduces hydrophilic components for weak pollutant bonding, thereby reducing cleaning difficulty without complicating the overall manufacturing process.
Solution Approach 2:
The invention changes the chemical composition parameters of the coating layers, specifically introducing phosphorus oxide-based components in the second layer that create hydrophilic surfaces. This parameter change reduces the bonding strength between pollutants and the coating surface from strong chemical bonds to weaker Van der Waals forces, enabling easier cleaning.
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 hydrophilic coating layers significantly reduce the bonding strength of pollutants, enabling more efficient cleaning by allowing pollutants to be easily removed with less physical force compared to traditional enamel coatings, as demonstrated by reduced swabbing frequency and improved cleaning efficacy.
Implementation Method 1
a second layer with a higher percentage of hydrophilic phosphorus oxide-based components, which absorbs pollutants through weaker Van der Waals interactions
Implementation Method 2
a second coating layer, that is coated on the base coating layer, and contains a greater percentage of hydrophilic components than the base coating layer

AI summary
A cooker and methods of manufacturing and controlling the same. The cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.
