Solution Overview

Problem

Existing cooking appliances with steam heating sources require complex assembly and maintenance due to separate steam inlet and outlet openings, which complicates the assembly process and makes cleaning difficult.

Innovation Solution

A cooking appliance design featuring a common structural unit with multiple steam inlet and outlet openings aligned laterally and approximately parallel to the cooking chamber walls, allowing for easier assembly and cleaning, with a temperature sensor integrated into the steam outlet opening for precise control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate steam inlet and outlet openings are installed in the cooking chamber, then steam control functionality is achieved, but assembly complexity and difficulty increase

Engineering Contradiction:
Improvesteam control functionalityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple steam openings (inlet and outlet) into a single integrated structural unit that can be installed as one piece in the cooking chamber. This merging of separate components into a unified module reduces assembly complexity while maintaining the required steam control functionality through multiple openings.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If multiple separate components are installed in the cooking chamber, then steam distribution is improved, but cleaning difficulty increases

Engineering Contradiction:
Improvesteam distribution efficiencyVSAvoidcleaning ease
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

By consolidating multiple steam openings into a single removable structural unit, the patent enables easier cleaning of the cooking chamber. The integrated unit can be removed as one piece, allowing straightforward access to all surfaces for cleaning, while still providing multiple openings for effective steam distribution throughout the chamber.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If steam openings are distributed throughout the cooking chamber, then steam coverage is improved, but assembly difficulty increases

Engineering Contradiction:
Improvesteam coverageVSAvoidassembly ease
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent segments the steam distribution system into a modular structural unit containing multiple openings that is pre-assembled outside the cooking chamber. This segmentation allows the complex multi-opening structure to be manufactured and tested separately, then installed as a single module, improving both steam coverage and assembly ease.

Inventive Principle:
Principle #1Segmentation

AI summary

The device (1) has a steam source (3) arranged over an outer side of a cooking chamber (2) to be heated, and steam inlet openings e.g. steam nozzle, provided in the cooking chamber to discharge steam from the steam source into the cooking chamber. A steam outlet opening (8) is provided in the cooking chamber, and the steam is blown out from the cooking chamber through the steam outlet opening. The openings are arranged in a structural unit (10) that is provided in the cooking chamber in an exchangeable manner. A temperature sensor detects characteristic temperature (12) of the chamber.
