Refrigerator Ice Compartment Sealing for Air Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators face challenges in maintaining the temperature separation between the refrigerator compartment and the ice compartment, leading to inefficiencies in ice production and storage due to air leakage and communication between compartments.
Innovation Solution
The implementation of a refrigerator design featuring a cabinet with a sealing part at the contact portion between the door and cabinet, an ice compartment with a door liner, an ice maker, an ice bin, and multiple sealing parts to prevent communication between compartments, including a second sealing part inserted into the ice compartment and a third sealing part adjacent to the hinge for enhanced sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single sealing part is used at the door contact portion, then the sealing function is provided, but air leakage occurs between the ice compartment and refrigerator compartment due to insufficient sealing
Solution Approach 1:
The sealing function is divided into multiple independent sealing parts: a first sealing part at the door contact portion, a second sealing part at the ice compartment door contact portion, and a third sealing part adjacent to the hinge. Each sealing part addresses specific leakage points, providing comprehensive sealing without requiring a single complex sealing structure.
Solution Approach 2:
Different sealing parts are positioned at specific locations where air leakage is most likely to occur: the contact portion between door and cabinet, the contact portion of ice compartment door, and the hinge area. This localized sealing approach provides effective sealing exactly where needed rather than uniform sealing throughout.
2Ease of operation
If the ice compartment door is opened frequently for ice dispensing, then user convenience is improved, but temperature separation between compartments deteriorates due to air communication
Solution Approach 1:
The sealing system is segmented into multiple parts that work together to maintain temperature separation even when the ice compartment door is opened. The first sealing part at the main door contact portion and the second sealing part at the ice compartment door contact portion create multiple barriers that prevent air communication between compartments.
Solution Approach 2:
The multiple sealing parts act as intermediary barriers between the ice compartment and refrigerator compartment. These sealing parts prevent direct air communication between the compartments, maintaining temperature separation while allowing the ice compartment door to be opened for ice dispensing.
3Productivity
If cooling air is allowed to flow between compartments, then ice production is improved, but temperature control in the refrigerator compartment deteriorates
Solution Approach 1:
The sealing system is divided into multiple parts that selectively control air flow. The sealing parts prevent uncontrolled air leakage between compartments while allowing the ice maker to access cooling air through designated pathways, thus maintaining both ice production efficiency and refrigerator compartment temperature control.
Solution Approach 2:
Different regions of the door assembly have different sealing characteristics. The sealing parts are positioned to prevent air leakage at critical interfaces while maintaining appropriate air flow paths for ice production. This localized control of air flow enables both ice production and temperature control to function effectively.

AI summary
Provided is a refrigerator that includes a cabinet, a refrigerator door, and a cabinet sealing part. The cabinet defines a storage compartment. The refrigerator door opens and closes the storage compartment. The cabinet sealing part is provided to a contact portion between the refrigerator door and the cabinet to prevent a communication between the storage compartment and an outside. The refrigerator door includes a door liner defining an ice compartment, an ice maker in the ice compartment, the ice maker generating ice, an ice bin storing ice generated by the ice maker, an ice compartment door opening and closing the ice compartment, and a plurality of sealing parts at positions spaced apart from each other. The sealing parts prevent a communication between the ice compartment and the storage compartment.
