Removable Commercial Oven Door Assembly for Wash-Down Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial cooking ovens in commercial kitchens face challenges in cleaning due to non-removable door assemblies, which hinder effective cleaning of glass panes and other components exposed to cooking residues and contaminants.
Innovation Solution
A door assembly design that includes an inner and outer panel with spaced glass panes, pivotally mounted to the oven housing, allowing for vertical upward separation and removal for cleaning, featuring multiple openings for fluid access between panels and glass panes to facilitate cleaning processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the door assembly is made non-removable, then the structural integrity and stability of the oven is improved, but the ease of cleaning the door assembly deteriorates
Solution Approach 1:
The door assembly is segmented into separable components including the door panel, glass pane, and pivot mechanism. This allows the door assembly to be detached from the oven housing for cleaning while maintaining structural integrity when assembled. The segmentation enables the door to be removed vertically upward from the pivot arrangement without compromising the overall structure.
Solution Approach 2:
The pivot arrangement provides a dynamic connection between the door assembly and housing, allowing the door to transition between fixed (closed) and movable (removed) states. The pivot mechanism with separable male and female members enables the door to be dynamically repositioned for cleaning while maintaining stability during normal operation.
2Ease of operation
If the door assembly is made removable, then the ease of cleaning the door assembly is improved, but the device complexity increases
Solution Approach 1:
The door assembly is divided into separable components with a pivot arrangement that has distinct male and female members. This segmentation allows for easy removal and reattachment while adding minimal complexity compared to a fully integrated design. The simple vertical lifting motion for removal reduces operational complexity.
Solution Approach 2:
The pivot mechanism is extracted as a separate functional element that can be easily engaged and disengaged. By taking out the pivot connection as a distinct feature with simple male-female geometry, the design achieves removability without significantly increasing overall device complexity.

AI summary
A cooking oven includes a housing defining an internal cooking cavity with an opening. A door assembly includes an inner panel framing an inner glass pane, and an outer panel framing an outer glass pane. A pivot arrangement pivotably mounts the door assembly to the housing. The pivot arrangement includes at least one pivot part located on the door assembly and at least one pivot part located on the housing. The pivot part of the door assembly is separable from the pivot part of the housing via vertically upward movement of the door assembly and upon separation of the pivot part of the door assembly from the pivot part of the housing the door becomes completely removed from the housing to enable the door assembly to be taken to a washing station for cleaning.
