Drying chamber assembly and air-cooled refrigerator having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying chamber assemblies in refrigerators are complex and occupy significant space, making it difficult to effectively store dry food materials like wolfberries, tea, mushrooms, and ophiocordyceps sinensis while minimizing the impact on the refrigerator's volume.
Innovation Solution
A compact drying chamber assembly with a simple structure, featuring a drawer sealing container with a drawer body, door, and upper cover that forms an independently sealed drying space, utilizing airflow from the freezing chamber through an air duct assembly to maintain low humidity and temperature, reducing the need for additional components and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional drying chamber assembly is installed in the refrigerator, then the drying function is achieved, but the refrigerator volume is significantly reduced and the structure becomes complex
Solution Approach 1:
The drawer body is designed to serve dual purposes: as a storage drawer for regular refrigerator use and as a drying chamber when positioned in the upper portion. This multi-functional design eliminates the need for a separate dedicated drying chamber, thereby preserving refrigerator volume while maintaining the drying function.
Solution Approach 2:
The drawer body is made movable between different positions within the refrigerator - it can be pulled out for drying operation or pushed back to restore full refrigerator space. This dynamic positioning allows the system to adapt between drying mode and space-saving mode, resolving the volume contradiction.
2Reliability
If a traditional drying chamber assembly with complete sealing structure is used, then the sealing performance is improved, but the device complexity increases
Solution Approach 1:
The drawer body's own structure serves as the sealing container, utilizing its inherent walls and structure to form the drying chamber. This self-service approach eliminates the need for additional separate sealing structures, reducing complexity while maintaining sealing performance through proper positioning and existing drawer construction.
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
The solution provides an efficient and space-saving method for storing dry food materials by creating a low-humidity, low-temperature environment within the refrigerator, ensuring the preservation of dry food while minimizing the impact on the refrigerator's volume and reducing manufacturing costs.
Implementation Method 1
An airflow inlet is formed in the drawer body and configured to supply an airflow to the drying space
Implementation Method 2
a drawer upper cover, disposed above the drawer body, so as to seal the top opening when the drawer body is completely pushed into the storage compartment

AI summary
A drying chamber assembly and a refrigerator are provided. The drying chamber assembly consists of a drawer-type sealing container which includes a drawer body, a drawer door and a drawer upper cover. The drawer body has an upward top opening. The drawer door is disposed at a front end of the drawer body and configured to push and pull the drawer body. The drawer upper cover is disposed above the drawer body to seal the top opening when the drawer body is completely pushed into the storage compartment and defines a drying space together with the drawer body and the drawer door. An airflow inlet is formed in the drawer body and configured to supply an airflow to the drying space. The drying chamber assembly directly covers and seals the top opening of the drawer body through the drawer upper cover.
