Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking appliances, such as ovens, face challenges in effectively removing contaminants like oil mist and combustion oxides from their inner walls, which can lead to contamination and unpleasant odors due to the difficulty in cleaning these substances, especially when they crystallize and adhere strongly.
Innovation Solution
A cooking appliance and method that utilizes a steam generator, water supplier, and pump assembly to heat the cooking room to a temperature that amorphizes contaminants, followed by controlled steam generation to facilitate easy removal of these substances, using a combination of convection heaters, heat coatings, and light sources for efficient heating and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cooking room is heated to high temperature for a long time to amorphize contaminants, then the cleaning effectiveness is improved, but the energy consumption and heating time increase
Solution Approach 1:
Water is supplied to the cooking room before heating begins, pre-positioning the cleaning agent so that it is immediately available to interact with contaminants when the heating process starts, eliminating the need for prolonged heating
Solution Approach 2:
The system utilizes the phase transition of water from liquid to vapor during heating. The supplied water evaporates and interacts with contaminants through condensation and hydrolysis reactions, enabling effective cleaning at lower temperatures and shorter durations compared to traditional thermal decomposition methods
2Reliability
If water is supplied continuously to the cooking room during heating, then the steam generation and cleaning effect are improved, but the water management complexity increases
Solution Approach 1:
Water is supplied in advance before the heating process begins, rather than continuously during heating. This preliminary supply allows the water to be distributed and positioned optimally throughout the cooking room, where it will naturally evaporate and interact with contaminants as heating proceeds
Solution Approach 2:
The system allows water to naturally evaporate and distribute itself throughout the cooking room through the heating process, without requiring complex pumping or distribution mechanisms during operation. The water self-regulates its evaporation rate based on the heating conditions
