Domestic refrigerator and food storage container with an air-conditioning device with a specific adjustment between a shell and an attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food storage containers for household refrigeration appliances require complex mechanical assemblies and operating elements to adjust air conditioning devices, leading to restricted movement and cramped situations, which complicates the operation and maintenance of ventilation.
Innovation Solution
A food storage container with a wall attachment that can be placed on a tray, featuring a lifting device with an elongated slide and tilting beam mechanism, allowing for manual adjustment of the wall attachment's position relative to the tray, enabling two operating states for air exchange and ventilation control without the need for additional motors or complex mechanical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid-based air conditioning device is used, then air exchange control is achieved, but the operation becomes cramped and requires complex mechanical assemblies
Solution Approach 1:
The air conditioning device is segmented into separate functional components: the wall attachment with lifting device is separated from the lid structure. This allows the air exchange control mechanism to be operated independently from the lid, eliminating the cramped operating conditions caused by integrating both functions in the lid.
2Measurement precision
If complex mechanical assemblies are used for air conditioning adjustment, then precise control is achieved, but the device complexity increases
Solution Approach 1:
The complex mechanical adjustment mechanisms are extracted from the lid and relocated to the wall attachment. The lifting device with its simple elongated slide and tilting beam provides precise air exchange control through a minimal mechanical structure, eliminating the need for complex assemblies while maintaining adjustment precision.
Solution Approach 2:
The air exchange control is achieved by changing the vertical position parameter of the wall attachment relative to the tray. The lifting device enables continuous adjustment of this position parameter, providing precise control over the ventilation gap size without requiring complex mechanical linkages.
3Extent of automation
If additional motors and complex components are added for air conditioning, then automation is improved, but the device complexity and space requirements increase
Solution Approach 1:
The lifting device is designed for manual operation by the user, eliminating the need for motors or automated actuation systems. The simple mechanical structure of the elongated slide and tilting beam allows direct user manipulation, achieving air conditioning control through self-service operation without adding complex automated components.

AI summary
One aspect of the invention relates to a food storage container (8, 8') for a household refrigeration appliance (1), comprising a tray (10) for receiving the food and an air conditioning device (23) by which air exchange between the environment and the interior of the food storage container (8, 8') is possible, and a wall attachment (17) separate from the tray (10) which can be placed on top of the tray (10), wherein the air conditioning device (23) has a lifting device (24) by which the wall attachment (17) is movable relative to the tray (10) in the vertical direction (y) of the food storage container (8, 8'), so that in a ventilation position of the air conditioning device (23) a ventilation gap (38) is formed between the tray (10) and the wall attachment (17). The invention also relates to a household refrigeration appliance (1).
