Refrigerator Ice-Making Compartment with Guided Cold Air
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators require users to bend to access ice makers, which are often located in freezing compartments beneath refrigerating compartments, making it inconvenient, especially for shorter users, and rearranging the ice maker to address this issue increases manufacturing costs and complexity.
Innovation Solution
Incorporating an ice making compartment within the refrigerating compartment and using a cold air guiding device to direct cold air from the heat exchanger to the ice making compartment, allowing for ice production without altering the refrigerator's capacity or freezing compartment position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ice maker is arranged in the freezing compartment, then ice can be made using cold air, but the user must bend to access it which is inconvenient
Solution Approach 1:
A cold air guiding device acts as an intermediary to transport cold air from the heat exchanger in the freezing compartment to the ice making compartment in the refrigerating compartment, enabling ice production without requiring the ice maker to be physically located in the freezing compartment where it would be inaccessible
2Ease of operation
If the ice maker is moved outside the freezing compartment, then ease of access is improved, but manufacturing costs and complexity increase
Solution Approach 1:
The cold air generated by the heat exchanger serves multiple functions: it cools the freezing compartment for food storage and is simultaneously guided to the ice making compartment to produce ice, eliminating the need for separate ice-making equipment and reducing manufacturing complexity
3Productivity
If cold air is guided to the ice making compartment, then ice production is enabled, but frosting may occur in the refrigerating compartment
Solution Approach 1:
The refrigerating compartment is segmented into distinct functional zones: a cold air guiding passage for transporting cold air to the ice maker, and a heating element zone that prevents frosting by locally heating the area where cold air passes through, maintaining temperature control without causing ice accumulation

AI summary
A refrigerator is disclosed which enables the user to easily take ice out of an ice maker without causing a variation in the capacity of the refrigerator or a limitation on the position of a freezing compartment. The refrigerator includes a refrigerator body which includes a freezing compartment and a refrigerating compartment, an ice making compartment which is arranged in the refrigerating compartment, to make ice, a heat exchanger which generates cold air for freezing food stored in the freezing compartment, and a cold air guiding device which guides the cold air generated by the heat exchanger to the ice making compartment, to enable the ice making compartment to make ice.
