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
An air-cooled refrigerator with a simplified drying chamber assembly featuring a drawer-type sealing container, airflow inlet, and a compact design that eliminates the need for additional structures like drawer cylinders, enhancing sealing performance and reducing installation complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional drying chamber assembly is used, then the drying function is achieved, but the structure becomes complex and occupies large volume
Solution Approach 1:
The patent merges the drying chamber with the refrigerator drawer structure, integrating the drying function into the existing drawer assembly. The drawer body itself serves as the drying chamber container, eliminating the need for separate drying chamber structures and reducing overall device complexity while maintaining the drying function.
Solution Approach 2:
The drawer assembly is designed to serve multiple functions: it acts as both a storage drawer and a drying chamber. The drawer body, drawer door, and sealing structures are universally utilized for both general storage and specialized drying purposes, reducing the need for dedicated separate components.
2Reliability
If a traditional drying chamber assembly is used, then the drying function is achieved, but the volume of the refrigerator is significantly occupied
Solution Approach 1:
The drying chamber is merged with the drawer structure, utilizing the drawer's existing volume for dual purposes. This integration allows the drying function to be achieved without adding separate dedicated space, thereby minimizing the impact on the refrigerator's overall volume.
Solution Approach 2:
The drying chamber components are nested within the drawer structure. The airflow inlet, sealing strips, and other drying-specific elements are integrated into the drawer body and door, creating a nested configuration that maximizes space utilization without increasing external dimensions.
3Reliability
If additional structures like drawer cylinders are added, then the drying chamber assembly is complete, but the installation complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates unnecessary complex components like drawer cylinders from the design. The drying chamber assembly is simplified to use only essential elements such as the drawer body, drawer door, sealing strips, and airflow inlet, removing redundant mechanical components that complicate installation and manufacturing.
Solution Approach 2:
The drawer structure itself provides the necessary support and functionality without requiring additional auxiliary components. The drawer body and door inherently provide the structural framework, and the sealing strips automatically provide the required sealing function when the drawer is closed, eliminating the need for complex installation procedures.
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 a compact, efficient, and cost-effective drying chamber that maintains a low-humidity, low-temperature environment suitable for long-term storage of dry food materials, preventing dampness and preserving nutritional ingredients.
Implementation Method 1
an airflow inlet (4001), formed in the drawer body (400) and configured to supply a cooling airflow in the freezing chamber (10b) to the drying space

AI summary
Provided are a drying chamber assembly and an air-cooled refrigerator having same. The drying chamber assembly may be composed of a drawer-type sealing container, the drawer-type sealing container comprising a drawer body (400), a drawer door (500) and a drawer upper cover (600). The drawer body (400) is used for receiving an object to be stored, has a top opening facing upwards, and is configured to be pulled out of or pushed into a storage compartment (10) in a controllable manner. The drawer door (500) is arranged at a front end of the drawer body (400) and used for pushing and pulling the drawer body (400). The drawer upper cover (600) is arranged above the drawer body (400) so as to seal the top opening when the drawer body (400) is completely pushed into the storage compartment (10) and defines a drying space together with the drawer body (400) and the drawer door (500). An airflow inlet (4001) is provided in the drawer body (400) 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 (400) by means of the drawer upper cover (600), such that the drying space, which is independently sealed, is formed inside the drawer body (400), without it being necessary to additionally provide structures such as a drawer cylinder, thereby simplifying the assembly of components of the drying chamber and reducing the manufacturing costs.
