Cleaning device for microwave oven
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning microwave ovens, such as using water and vinegar, are ineffective in removing tough stains and pose risks due to splashing and handling issues, as they lack specialized tools to cover the interior and handle heat safely.
Innovation Solution
A cleaning device with a body part, head cap, and intermediate part that includes multiple through holes for steam venting, a locking mechanism for secure assembly, and optional non-heat handles for safe handling, designed to accommodate cleaning liquids and prevent splashing during microwave heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water and vinegar are poured into a bowl or container for cleaning, then the cleaning liquid can be heated to produce steam, but the bowl or container cannot cover the splash created during heating and may cause explosion risk
Solution Approach 1:
The cleaning device is divided into multiple components: a body part for holding cleaning liquid, a head cap with through holes for steam venting, and an intermediate part for connection. This segmentation allows the head cap to cover and contain the heating process while providing controlled steam release, preventing splash and explosion risks while maintaining cleaning effectiveness
Solution Approach 2:
The head cap is designed with specific local properties: it covers the entire opening of the body part to prevent splash, but includes through holes at specific locations to allow steam venting. This local differentiation of qualities (covering vs. venting) resolves the contradiction between containment safety and steam release effectiveness
2Object-affected harmful factors
If a lid or seal is used to cover the container, then splash can be prevented, but there is a chance of explosion due to pressure buildup
Solution Approach 1:
The head cap functions as a porous structure with multiple through holes distributed across its surface. This porous design allows the cap to prevent splash while simultaneously providing multiple escape routes for steam, preventing pressure buildup and explosion risks that would occur with a solid sealed lid
3Productivity
If the container is heated in the microwave oven, then steam is generated for cleaning, but the container becomes extremely hot and unsafe to handle
Solution Approach 1:
The cleaning device incorporates asymmetric material selection: the body part and head cap are made of microwave-transparent materials that allow efficient steam generation, while the handle is made of microwave-absorbing or heat-insulating material that remains cool. This asymmetric material distribution enables efficient cleaning while ensuring safe handling
4Reliability
If a specialized cleaning device with multiple components is designed, then cleaning effectiveness and safety are improved, but the device complexity increases
Solution Approach 1:
The cleaning device employs a nested structure where the intermediate part connects the body part and head cap, with the head cap fitting over the body part opening. This nesting arrangement achieves reliable cleaning effectiveness and safety through multiple components while minimizing overall structural complexity and facilitating easy assembly and disassembly
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 device effectively cleans microwave ovens by quickly and concentratedly dispersing steam to cover the entire interior, preventing splashing and allowing safe handling, thus providing a more efficient and safer cleaning experience compared to traditional methods.
Implementation Method 1
heated up by the microwave oven (radiation)

AI summary
Provided are cleaning devices adapted for a microwave oven. A head cap of the cleaning device includes multiple through holes, and thus steam generated by heating a cleaning liquid can flow out of the through holes in a faster and more concentrated mode. Using the cleaning device of this disclosure, the cleaning operation for the microwave oven is more convenient, and safety hazard such as explosion or splashing is also prevented as well.
