Oven with combustion promoting coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens face contamination issues due to oil mist and combustion oxides deposited on the inner walls during cooking, making cleaning difficult and inefficient.
Innovation Solution
An oven design featuring a collision area with a catalyst coating and auxiliary heater, where circulated air collides with the oil mist, promoting its combustion and collection, thereby concentrating the oil mist for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If oil mist is distributed all over the inner wall of the cooking compartment, then the contamination area increases, but cleaning becomes more difficult and time-consuming
Solution Approach 1:
The patent extracts the harmful oil mist from the general circulation and concentrates it in a specific collision area by using a baffle structure that redirects air flow, separating the contamination problem from the entire cooking compartment to a localized region
Solution Approach 2:
The patent applies local quality by creating a specific collision area with unique structural features (baffle, angled surface) that causes oil mist to accumulate there, making that local region the designated contamination zone while keeping the rest of the cooking compartment clean
2Productivity
If a catalyst coating is applied to the collision area, then oil mist combustion is promoted, but the device complexity increases
Solution Approach 1:
The catalyst coating on the collision area enables the system to automatically combust oil mist through the existing air circulation and heating elements, allowing the oven to self-clean without requiring additional active components or complex control systems
Solution Approach 2:
The patent replaces mechanical cleaning systems with a chemical combustion process facilitated by the catalyst coating, which breaks down oil mist through chemical reactions rather than physical removal mechanisms
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 effectively collects and burns the oil mist within the oven, reducing the area that needs cleaning and maintaining a cleaner cooking compartment, enhancing user convenience and efficiency.
Implementation Method 1
The collision area includes a catalyst coating portion disposed on a surface of the collision area to act as a catalyst when an oil mist trapped on the collision area by the collision of the circulated air and the collision area is burned.
Implementation Method 2
The collision area includes a face heating coating portion disposed on a surface of the collision area to heat an oil mist collected on the collision area by the collision of the circulated air with the collision area is burned.
Implementation Method 3
The collision area includes an auxiliary heater disposed adjacent to the collision area to heat an oil mist trapped on the collision area by the collision of the circulated air with the collision area is burned.
Implementation Method 4
a fan disposed at one side of the cooking compartment to circulate air inside the cooking compartment
Implementation Method 5
a heater applying heat to the cooking compartment

AI summary
An oven includes a collision area in which air circulating inside a cooking compartment is collided to reduce the pollution inside of the cooking compartment. A collision area may collectively collect an oil mist condensed by the collision of the air. The collision area is disposed on the side where the flow of air is changed to induce air collision and guide the air to the front side of the cooking compartment to increase air circulation and increase ease of cleaning inside the cooking compartment.
