Air channel assembly and refrigerator having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-cooled refrigerators face issues with water vapor condensation leading to water accumulation and icing, which increases energy consumption and reduces operational efficiency, as well as causing trouble in cleaning ice and air volume loss.
Innovation Solution
An air channel assembly with a casing featuring separate air and drainage guide portions, where the air-supply guide portion directs air to a bottom air supply port and the drainage guide portion directs water to a drainage port, with their guide directions being opposite, reducing air volume loss and preventing frosting by effectively separating air and water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water drainage port is arranged at the bottom air supply port, then water can be drained, but air volume is lost and frosting occurs
Solution Approach 1:
The patent divides the bottom wall into separate functional zones: a drainage guide portion with drainage ports for water removal, and an air supply guide portion with air supply ports for air circulation. This segmentation prevents air and water from mixing, allowing water drainage without air volume loss and preventing frosting by keeping the air supply path clear of condensed water.
2Reliability
If water drainage port is arranged at the bottom air supply port, then water can be drained, but frosting increases energy consumption
Solution Approach 1:
The patent divides the bottom wall into separate functional zones: a drainage guide portion with drainage ports for water removal, and an air supply guide portion with air supply ports for air circulation. This segmentation prevents air and water from mixing, allowing water drainage without air volume loss and preventing frosting by keeping the air supply path clear of condensed water.
3Device complexity
If air and water flow paths are not separated, then structure is simple, but air volume loss and frosting occur
Solution Approach 1:
The patent divides the bottom wall into separate functional zones: a drainage guide portion with drainage ports for water removal, and an air supply guide portion with air supply ports for air circulation. This segmentation prevents air and water from mixing, allowing water drainage without air volume loss and preventing frosting by keeping the air supply path clear of condensed water.
