Refrigerator Diffusion Layer Positioning for Moisture-Sensitive Goods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration devices with air circulation struggle to maintain optimal storage conditions for both moisture-sensitive and dryness-sensitive goods, as existing diffusion layers can lead to inadequate air flow and condensation issues, causing either drying out or moisture penetration.
Innovation Solution
A refrigeration device with a diffusion layer that can be moved between two positions, allowing for adjustable airflow through the compartment, using a movable frame and actuation mechanism to control air circulation, ensuring optimal conditions for different types of refrigerated goods by bypassing the diffusion layer when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a diffusion layer is used to slow down air flow, then sharp jet of cold air is prevented from hitting goods, but condensation drainage becomes insufficient
Solution Approach 1:
The diffusion layer is designed to be dynamically positionable between covering and displaced states. When covering the air passage openings, it slows down air flow to prevent sharp jets from hitting goods. When displaced to the second position, it allows free air circulation through the air passage openings, enabling adequate condensation drainage. This dynamic positioning resolves the contradiction between protecting goods from cold air jets and maintaining efficient condensation drainage.
2Stability of the object's composition
If the diffusion layer is fixed in position, then storage conditions are consistent, but the system cannot adapt to different types of refrigerated goods with different moisture sensitivity
Solution Approach 1:
The movable diffusion layer enables the refrigeration system to adapt to different types of refrigerated goods by adjusting its position. For moisture-sensitive goods, the diffusion layer can be positioned to cover openings and provide gentle air flow. For goods requiring better drainage, the diffusion layer can be displaced to allow free air circulation. This dynamic adaptability maintains stable storage conditions appropriate for each type of goods while providing versatility across different storage needs.
Solution Approach 2:
The patent applies local quality by allowing different air flow conditions in different compartments or at different times based on the type of goods stored. Each compartment can have its diffusion layer positioned independently to create locally optimized storage conditions - some compartments may require diffusion layer coverage while others need free air flow, depending on the specific goods stored in each location.

AI summary
The invention relates to a refrigerating device comprising an evaporator (15) and at least one compartment (7), which is cooled by circulating air from and to the evaporator (15), wherein a diffusion layer (50) can be displaced between a first position, in which air passage openings (30) distributed in a wall (29) separating the compartment (7) from a distribution chamber (27) are covered by the diffusion layer (50), and a second position, in which it allows air to flow from the evaporator (15) through the distribution chamber (27) into the compartment (7) while bypassing the diffusion layer (50).
