Control box for a cooking device and cooking device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The control box of cooking appliances is difficult to clean due to its inaccessible design, leading to inefficiencies in removing deposits caused by fatty vapors, which can affect its functionality over time.
Innovation Solution
Incorporating a cleaning agent inlet aligned with the steam flow path between the steam inlet and outlet, with outlets directed towards the ceiling or side walls, and utilizing a fanning structure or baffle plates to ensure even distribution of cleaning agents, along with a grid structure to shield high-frequency radiation and facilitate cleaning of hard-to-reach areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the control box is designed to be compact and integrated into the cooking appliance, then the appliance structure is simplified and space is saved, but the control box becomes difficult to access for cleaning
Solution Approach 1:
The control box is segmented into multiple cleanable sections with accessible openings. The housing includes removable panels or openings that allow cleaning agents to reach internal surfaces, particularly the ceiling area where deposits accumulate. This segmentation maintains the compact external form while providing internal access paths for cleaning operations.
2Reliability
If the control box housing is sealed to prevent grease and vapor ingress, then protection against contaminants is improved, but cleaning becomes more difficult due to restricted access
Solution Approach 1:
Cleaning access openings are extracted from the sealed housing structure. These openings allow cleaning agents to be introduced into the control box interior while maintaining the sealed configuration during normal operation. The openings can be closed during cooking to maintain sealing and opened during cleaning to provide access.
Solution Approach 2:
A cleaning agent delivery system acts as an intermediary between the external cleaning source and the internal control box surfaces. This system includes channels, nozzles, or spray mechanisms that transport cleaning agents through the housing structure to reach hard-to-access areas like the ceiling, enabling effective cleaning without compromising the sealed design.
3Ease of operation
If cleaning agents are introduced from the bottom or side of the control box, then access is easier, but even distribution of cleaning agent across all surfaces including the ceiling is difficult to achieve
Solution Approach 1:
The cleaning agent delivery system utilizes multiple dimensions for distribution. Instead of single-point introduction from bottom or side, the system employs multiple introduction points distributed across different locations and orientations. This includes upward-facing nozzles from the bottom, side-wall nozzles, and potentially ceiling-mounted nozzles that spray downward, creating multi-directional coverage that ensures uniform distribution across all surfaces including horizontal ceilings.
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
This design allows for efficient and even distribution of cleaning agents, effectively addressing the challenge of accessing and removing deposits within the control box, enhancing its maintenance and operational reliability.
Implementation Method 1
the cleaning agent inlet is arranged between the steam inlet and the steam outlet with respect to a steam flow path. Cleaning agent can be introduced into the control box particularly easily through the cleaning agent inlet
Implementation Method 2
By orienting the outlet opening toward the ceiling, the cleaning agent is specifically directed to the main dirt spots in the control box, where it is atomized and distributed on the ceiling
Implementation Method 3
a deflection element provided at the outlet opening, which is designed to redirect a cleaning agent flow exiting the outlet opening toward the ceiling
