Solution Overview
Problem
Existing cooking appliances face challenges in efficiently generating and managing steam for cooking, leading to potential contamination and increased cooking time due to boiling over and inefficient steam generation.
Innovation Solution
A steam generator with a steam case and cover, divided into multiple spaces to heat water efficiently, using a steam heater and interference members to prevent boiling over, and a discharge system to supply superheated steam into the cooking chamber, while preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is heated to generate steam in a single space, then steam generation speed increases, but water boils over and contaminates the cooking space
Solution Approach 1:
The steam generation space is divided into multiple spaces (first space, second space, third space) arranged in sequence. Water flows through these spaces sequentially, allowing controlled heating and steam generation without boiling over into the cooking chamber. This segmentation enables efficient steam production while preventing contamination.
2Device complexity
If a single heater is used to heat water, then device complexity is reduced, but steam generation efficiency and temperature control are insufficient
Solution Approach 1:
The heating system is segmented into multiple heaters (first heater in the first space, second heater in the second space, third heater in the third space). Each heater independently controls the temperature in its respective space, enabling efficient water heating and superheated steam generation while maintaining manageable device complexity through modular configuration.
3Loss of time
If water is heated rapidly to reduce cooking time, then cooking efficiency improves, but water boils over and introduces contamination
Solution Approach 1:
The rapid heating process is segmented across multiple spaces with controlled temperature gradients. Water is heated progressively through the first, second, and third spaces, allowing fast steam generation without violent boiling that would cause overflow and contamination.
Solution Approach 2:
The multiple heated spaces act as intermediaries between the heat source and the steam discharge point. Water and steam flow through these intermediate spaces, which control the heating rate and prevent direct contact between boiling water and the cooking chamber, thus avoiding contamination while maintaining rapid steam production.

AI summary
A steam generator is provided. The steam generator may include a steam chamber, a steam heater to supply heat into the steam chamber, a water supply, through which water to generate steam may be supplied into the steam chamber, one or more interference members disposed in the steam chamber to interfere with a flow of the water introduced through the water supply, and at least one discharge to discharge the steam generated in the steam chamber. The one or more interference members may be disposed under the at least one discharge and above the water supply.
