Sealed Icebox Airflow and Drainage for Remote Ice Makers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigerator appliances with a bottom freezer configuration, locating the ice maker in the freezer chamber can be inconvenient, and there is a need for an ice making system that can operate independently of the freezer chamber.
Innovation Solution
An ice making appliance with a sealed icebox compartment containing a heat exchanger and a mold body for forming ice, along with a defrost conduit and air circulation system, allowing the ice maker to be positioned outside the freezer chamber, proximate to the fresh food chamber, and maintaining efficient thermal communication with the freezer chamber through convection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ice maker is located in the bottom freezer chamber, then the ice maker can operate at freezer temperatures, but the ice maker becomes inconvenient to access and locate
Solution Approach 1:
The ice making system is separated from the freezer chamber into a dedicated sealed icebox compartment. This segmentation allows the ice maker to be positioned in a convenient location (such as the fresh food chamber or door) while maintaining independent temperature control through the sealed compartment design, thus resolving the contradiction between accessibility and temperature reliability.
Solution Approach 2:
A sealed icebox compartment acts as an intermediary between the ice maker and the external environment. This intermediary structure enables the ice maker to be located outside the freezer chamber while still maintaining the necessary cold environment through thermal insulation and controlled heat exchange, solving the conflict between convenient location and temperature control.
2Ease of operation
If the ice maker is positioned outside the freezer chamber, then ice production becomes more convenient, but thermal communication with the freezer chamber must be maintained
Solution Approach 1:
The sealed icebox compartment serves as a thermal intermediary, allowing the ice maker to be positioned outside the freezer chamber while maintaining efficient thermal communication. The compartment's insulation and controlled heat exchange mechanisms enable energy-efficient operation at remote locations, resolving the contradiction between location convenience and thermal efficiency.
Solution Approach 2:
The ice maker is nested within a sealed icebox compartment that can be positioned within or adjacent to the refrigerator structure. This nested configuration allows the ice maker to be located in a convenient position (such as within the fresh food chamber or door) while the sealed compartment maintains thermal efficiency by minimizing heat transfer, thus resolving the energy efficiency contradiction.
3Adaptability or versatility
If a sealed icebox compartment is used, then the ice maker can be positioned remotely, but the compartment requires air circulation and defrost mechanisms
Solution Approach 1:
The sealed icebox compartment is designed with multi-functional integrated systems. The air circulation conduit serves both cooling and defrost functions, while the defrost conduit handles both meltwater removal and temperature regulation. This multi-functionality reduces the overall system complexity despite the added versatility of remote positioning, resolving the contradiction between adaptability and device complexity.
