Cooking Oven Filter Seat for Elevated Additive Tab Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Professional cooking ovens face challenges with manual cleaning, which is time-consuming, and existing automatic or semi-automatic cleaning systems can be expensive and corrosive, potentially damaging the oven's metal components, especially when using compressed powder tablets that can corrode the bottom wall if not activated promptly.
Innovation Solution
A cooking oven with a cleaning system featuring a filter positioned within the cooking chamber to support washing/rinsing additive tabs, keeping them spaced from the bottom wall, allowing for efficient liquid contact and preventing corrosion, while ensuring all liquid contacts the tabs for faster melting and effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed powder tablets are positioned on the bottom wall of the cooking chamber, then the cleaning agent can be activated by residual humidity, but this causes local high concentration and corrosion of the bottom wall
Solution Approach 1:
The patent extracts the cleaning agent (additive tab) from direct contact with the bottom wall by positioning it on a support structure elevated above the bottom wall. This separation prevents the harmful local concentration effect while maintaining cleaning functionality through liquid circulation.
Solution Approach 2:
The support structure acts as an intermediary between the cleaning agent and the bottom wall. It allows the additive tab to be positioned in a location where it can be effectively activated by circulating liquid without directly contacting the bottom wall, thus preventing corrosion.
2Productivity
If compressed powder tablets are positioned on the bottom wall, then cleaning can proceed, but the melting process is slow because the bottom wall is not fully contacted by cleaning water
Solution Approach 1:
The patent uses hydraulic circulation to pump cleaning liquid through the cooking chamber, ensuring comprehensive contact with the additive tab. This forced circulation accelerates the melting and activation of the cleaning agent compared to passive diffusion from bottom wall positioning.
Solution Approach 2:
By elevating the additive tab to a different vertical dimension (above the bottom wall), the patent enables multi-directional contact with circulating liquid, increasing the surface area exposed to cleaning solution and accelerating the melting process.
3Object-affected harmful factors
If manual cleaning is used, then no corrosive chemicals are involved, but the process is burdensome and time-consuming
Solution Approach 1:
The system enables self-service cleaning by automatically circulating cleaning liquid through the cooking chamber and activating additive tabs. This automated process eliminates the need for manual labor while using controlled, less corrosive cleaning agents compared to traditional methods.
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 solution enables optimal, rapid cleaning of the oven without damaging the bottom wall, reducing the risk of corrosion and shortening the cleaning cycle by ensuring all liquid contacts the additive tabs, thus improving hygiene and maintenance efficiency.
Implementation Method 1
a filter arranged at least partially within the cooking chamber for preventing solid bodies of prefixed dimensions from entering the one or more cooking chamber outlets, while letting liquids flow from the cooking chamber into the one or more cooking chamber outlets
Implementation Method 2
melting the one or more washing/rinsing additive tabs with the washing/rinsing liquid and forming a washing/rinsing solution
