Ice-Making Chamber Layout for Door Insulation and Cooling Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigerators with an ice-making chamber, the space of the cooling chamber is reduced due to the large width of the ice-making chamber, which also compromises insulation performance and cool air flow, as the ice-making chamber's structure interferes with the cool air channel and door thickness.
Innovation Solution
A refrigerator design where a protrusion portion is formed on the first sidewall of the ice-making chamber, allowing the ice-making chamber door to be thicker without altering the cool air channel's structure, thereby increasing the cooling chamber space by redistributing the protrusion width and maintaining insulation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the width of the ice-making chamber is increased, then the ice-making capacity is improved, but the space of the refrigerating chamber is reduced
Solution Approach 1:
The connecting duct is repositioned from a lateral connection to a connection through the rear surface of the ice-making chamber. This dimensional change allows the ice-making chamber to be positioned more optimally within the door, improving ice-making capacity while minimizing intrusion into the refrigerating chamber space.
Solution Approach 2:
The ice-making chamber door is divided into functionally independent sections: the ice-making chamber body and the door portion. The connecting duct is specifically positioned in the rear surface of the chamber body, separating the cooling air supply function from the door structure, allowing independent optimization of each component.
2Reliability
If the thickness of the refrigerating chamber door is increased, then the insulation performance is improved, but the space of the refrigerating chamber is reduced
Solution Approach 1:
The connecting duct is positioned at the rear surface of the ice-making chamber rather than extending laterally through the door thickness. This allows the door to maintain adequate thickness for insulation while accommodating the duct in a different spatial dimension that does not compromise refrigerating chamber space.
3Quantity of substance
If the structure of the cool air channel is changed to increase ice-making chamber width, then the ice-making capacity is improved, but the cool air flow efficiency is reduced
Solution Approach 1:
The cool air channel is reconfigured to connect through the rear surface of the ice-making chamber rather than through lateral passages. This maintains efficient, direct airflow path from the freezing chamber through the duct to the ice-making chamber, preserving cool air flow efficiency while allowing the ice-making chamber to have greater width.
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
This design enhances the thickness of the ice-making chamber door while maintaining the cool air channel's integrity, increasing the refrigerating chamber's space without reducing insulation performance or affecting cool air flow.
Implementation Method 1
a refrigerator body 110 formed with a cooling chamber 120, 130
Implementation Method 2
a door 125 configured to open and close the cooling chamber 120, 130
Implementation Method 3
a region of the ice-making chamber 150 is inserted into the refrigerating chamber 120, and thus when the width of the ice-making chamber 150 is large, the space of the refrigerating chamber 120 in the refrigerator may be reduced to that extent

AI summary
Disclosed herein is a refrigerator having an ice-making chamber, and the refrigerator may include a refrigerator body (110) and an ice-making chamber (150), and the ice-making chamber (150) may include an ice-making chamber body (151) one side of which is opened, a connecting duct (171) provided in a first sidewall (161) of the ice-making chamber (150) to be connected to the refrigerator body (110), an ice-making chamber door (190) provided at a second sidewall (162) of the ice-making chamber (150) to open and close the ice-making chamber (150), and a protrusion portion (181) formed to be protruded at the first sidewall (161). Accordingly, the thickness of the ice-making chamber door (190) can be secured without changing a cool air channel of the ice-making chamber, thereby increasing a cooling chamber.
