Steam cooking appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam cooking appliances face challenges in maintaining sufficient cooking space due to the volume occupied by water tanks and often experience steam supply interruptions during cooking.
Innovation Solution
A steam cooking appliance design featuring a separable water tank positioned on a backguard outside the cooking cavity, with a steam supply unit outside the cavity to heat water from the tank and generate steam, ensuring continuous steam supply without reducing the cooking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a water tank is added to the steam cooking appliance, then water supplementation becomes easier, but the cooking space is reduced due to the volume occupied by the water tank
Solution Approach 1:
The water tank is extracted from the cooking cavity and positioned on the backguard instead. This separation allows the water tank to be easily accessible for refilling while keeping the cooking space completely clear and unaffected by the water tank's volume.
2Reliability
If the water tank size is increased to ensure sufficient water supply, then steam supply continuity is improved, but the cooking space is further reduced
Solution Approach 1:
By extracting the water tank from the cooking cavity and placing it on the backguard, the invention enables the water tank to be enlarged without compromising cooking space. This ensures continuous steam supply while maintaining adequate cooking volume.
3Device complexity
If the water tank is positioned inside the cooking cavity, then the appliance structure is simplified, but electronic components are exposed to heat and moisture
Solution Approach 1:
The water tank is extracted from the cooking cavity and positioned on the backguard, separating it from the heat and moisture environment. This protects electronic components from harmful exposure while maintaining a compact and integrated appliance structure.
Solution Approach 2:
The backguard serves as an intermediary structure that accommodates the water tank in a position that is both accessible and protected from the cooking environment's heat and moisture, while still maintaining structural integration.
