Multizone Oven Jet Plate Cleaning Using Integrated Spray Inlet Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multizone ovens face challenges in efficiently cleaning the cavity and jet plates, and in providing uniform steam generation and sealing between cooking chambers.
Innovation Solution
The solution involves directing pressurized cleaning spray into the jet plates through cleaning spray inlet ports, using small air holes in the baffle wall to enhance suds production, and employing a spray diverter for effective cleaning solution distribution. Additionally, separate motors and control chains are used for mechanical atomization and convection blower speed, and an improved steam generator design is implemented. The oven also features enhanced sealing with a front gasket and separate drain tubes for each cooking chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning spray is directed into jet plates through inlet ports, then cleaning efficiency is improved, but device complexity increases
Solution Approach 1:
The cleaning spray inlet ports are integrated into the jet plate structure itself, with the spray nozzles nested within the jet plate body. The spray channels are formed within the jet plate thickness, creating a nested configuration where the cleaning system is embedded within the functional component rather than being a separate external system.
Solution Approach 2:
The jet plates serve dual functions: they distribute cooking heat through their slots and openings during normal operation, and they receive cleaning spray through integrated inlet ports during cleaning cycles. This multi-functionality eliminates the need for separate cleaning apparatus, reducing overall system complexity while maintaining high cleaning efficiency.
2Quantity of substance
If small air holes are provided in the baffle wall, then suds production is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The baffle wall is designed with a porous structure containing multiple small air holes that allow controlled airflow through the wall. These holes enable air to mix with cleaning solution to generate suds in the cooking cavity, enhancing cleaning effectiveness. The porous nature of the baffle wall integrates the air supply function directly into the structural component.
3Reliability
If separate motors and control chains are used for mechanical atomization and convection blower, then steam generation consistency is improved, but device complexity increases
Solution Approach 1:
The oven system is divided into independent control zones with separate motors for the mechanical atomizer and the convection blower. Each motor has its own control chain, allowing independent adjustment of steam generation and air circulation. This segmentation enables precise control of each function without interference, ensuring consistent steam generation while maintaining the ability to optimize performance separately.
4Manufacturing precision
If spray diverter is added for cleaning solution distribution, then cleaning uniformity is improved, but device complexity increases
Solution Approach 1:
The spray diverter is strategically positioned to direct cleaning solution to specific areas of the jet plates that require enhanced cleaning. Rather than uniform spray distribution, the diverter creates localized high-concentration cleaning zones where cooking residues accumulate most, optimizing cleaning effectiveness in critical areas while maintaining overall system simplicity.
Applied Scientific Principles

Function Achieved in This Case
This approach improves cavity and jet plate cleaning efficiency, ensures consistent steam generation, enhances sealing between cooking chambers, and maintains uniformity across cooking chambers, thereby improving overall oven performance.
Implementation Method 1
directing pressurized cleaning spray into the jet plates while installed within the oven through cleaning spray inlet ports
Implementation Method 2
providing small air holes in the baffle wall of the upper jet plate... an increased amount of airflow is provided upward to the pool of cleaning fluid when the blower is on to produce more trapped air in the form of soap bubbles
Implementation Method 3
low pressure venturi drawing water through the holes to clean the interior of the jet plates
Implementation Method 4
combi-ovens cook using combinations of convection and steam... steam can also reduce water loss from the food
Implementation Method 5
In convection cooking, heated air is circulated rapidly through the cooking compartment to break up insulating, stagnant layers of air around the food, thereby increasing the rate of heat transfer
Implementation Method 6
enhanced sealing with a front gasket and separate drain tubes for each cooking chamber

AI summary
A multi cavity oven provides improved cavity and jet plate cleaning by directing pressurized cleaning spray into the jet plates while installed within the oven through cleaning spray inlet ports in the walls of the removable jet plates. By directing cleaning spray directly into the interior of the jet plates, cooking juices that fall through the slots and openings and into the air passageway of the jet plates can be pressure cleaned and drained from the interior of the jet plates without removing the jet plates from the oven cavity.
