Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator designs face challenges in implementing a quick-chilling chamber, including complex structures that increase manufacturing costs and reduced cooling speed, as well as non-uniform chilling of stored food or drink when using part of the refrigerating compartment.
Innovation Solution
A refrigerator design that incorporates a quick-chilling chamber cooled by direct cold air from a compressor or indirect cold air from the freezing compartment, utilizing a door of the freezing compartment to enhance space efficiency and rapidly chill objects, with a cooling fan system to control the airflow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate drawer-type quick-chilling chamber is implemented, then chilling function is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The quick-chilling chamber is merged with the freezing compartment door, combining two functions into one structure. The door assembly serves both as the freezing compartment closure and as the quick-chilling chamber, eliminating the need for a separate drawer-type chamber and reducing overall structural complexity.
Solution Approach 2:
The freezing compartment door is designed to serve multiple functions: it acts as the closure for the freezing compartment and simultaneously houses the quick-chilling chamber. This multi-functional design allows the same structure to provide both freezing storage and rapid chilling capabilities without requiring additional components.
2Device complexity
If part of the refrigerating compartment is used as quick-chilling chamber, then space efficiency is improved, but cooling speed decreases
Solution Approach 1:
The quick-chilling chamber is designed with localized high-quality cooling features, including direct cold air inlet passages that provide intense cooling specifically within the quick-chilling chamber. This localized cooling enhancement ensures rapid chilling performance in the specific region where it is needed, without compromising the overall space efficiency of the refrigerating compartment.
3Speed
If cold air is supplied directly from compressor to quick-chilling chamber, then cooling speed is improved, but temperature control precision worsens
Solution Approach 1:
The system dynamically adjusts the cooling mode based on real-time temperature conditions. A controller monitors the temperature in the quick-chilling chamber and dynamically switches between direct cold air supply (for rapid cooling when temperature is high) and indirect cold air supply through the freezing compartment (for precise temperature maintenance when the target temperature is approached), optimizing both cooling speed and temperature control precision throughout the chilling process.

Implementation Method 1
a compressor that supplies cold air to at least one of the freezing compartment, the refrigerating compartment, or the quick-chilling chamber
Implementation Method 2
allow direct cold air supplied from the compressor or indirect cold air supplied through the freezing compartment to flow into the quick-chilling chamber

AI summary
A refrigerator is provided. The refrigerator includes a freezing compartment, a refrigerating compartment, a quick-chilling chamber, and a compressor that supplies cold air to at least one of the freezing compartment, the refrigerating compartment, or the quick-chilling chamber. The quick-chilling chamber is cooled by first cold air introduced through the compressor or second cold air introduced through the freezing compartment.
