Movable Evaporator Layout for Cleanable Refrigerated Display Cases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerated display cases face challenges in effectively cleaning the evaporator area due to its fixed position, which hinders efficient maintenance and hygiene.
Innovation Solution
The evaporator is positioned above or next to the display area and can be moved into a cleaning position, allowing for improved accessibility and separate cleaning of its rear or upper sides, facilitated by a rolling or sliding device and pivot mechanism, enabling easy transfer and detachment for thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the evaporator is arranged below the display area for fixed installation, then space utilization is improved, but cleaning accessibility deteriorates
Solution Approach 1:
The evaporator is made movable between a first position (below the display area for space-efficient installation) and a second position (offset toward the center for cleaning accessibility). This dynamic repositioning capability allows the system to optimize both space utilization and cleaning accessibility at different operational stages.
Solution Approach 2:
The evaporator is designed as a separable component that can be detached from its mounting position. The connection between the evaporator and the display case is segmented through detachable connections, allowing the evaporator to be removed independently for thorough cleaning while leaving the display structure intact.
2Ease of operation
If the evaporator is made movable for cleaning access, then cleaning accessibility is improved, but device complexity increases
Solution Approach 1:
The evaporator incorporates a movable mounting mechanism with detachable connections that enable simple repositioning between installation and cleaning positions. This dynamic design provides cleaning accessibility without requiring complex mechanical systems, as the evaporator can be moved and reconnected using straightforward attachment mechanisms.
3Ease of operation
If the evaporator is positioned above the display area, then cleaning accessibility is improved, but space utilization deteriorates
Solution Approach 1:
The evaporator is designed to dynamically reposition between being located below the display area (optimizing space utilization) and being moved to the center area (optimizing cleaning accessibility). This eliminates the need for permanent placement above the display area while still providing cleaning access when needed.

AI summary
The cooler (10) has an insulating tub (20) with a trough base (22). A shelf surface (18) is positioned in the insulating tub for delivery of goods. An evaporator (40) is arranged in the insulating tub. A fan unit (60) is provided for generating a circulating air flow for cooling goods by the evaporator. The evaporator is arranged above or in the height range of shelf surface for goods. The evaporator is moved between an operating position in a peripheral region of the insulating tub and center cleaning position.
