Refrigerator Upper Duct Deodorizing Device for Space and Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators face issues with deodorizing devices that protrude forward, reducing storage space and deodorization efficiency, and are exposed when the door is opened, affecting the outer appearance and cold air flow.
Innovation Solution
A deodorizing device is positioned on the upper surface of the refrigerator's storage space, adjacent to the cold air discharge port, with an inclined design that minimizes exposure and enhances air circulation, using a deodorizing filter and sterilization LED to improve deodorization and sterilization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the deodorizing device is placed on the rear wall of the refrigerator, then it can be installed in the available space, but it protrudes forward causing loss of storage space and reduced deodorization efficiency
Solution Approach 1:
The deodorizing device is relocated from the rear wall to the upper surface of the storage space, changing its spatial dimension. This allows the device to be positioned above the cold air discharge port without protruding into the storage space, thereby preserving storage volume while maintaining deodorization functionality.
Solution Approach 2:
The cold air discharge port serves as an intermediary location where the deodorizing device is positioned. By placing the device adjacent to the discharge port on the upper surface, the cold air naturally flows through the deodorizing device, enabling effective deodorization without requiring additional protruding structures into the storage space.
2Ease of manufacture
If the deodorizing device is placed on the rear wall, then it can be installed, but it is directly exposed when the door is opened compromising the outer appearance
Solution Approach 1:
The deodorizing device is relocated from the rear wall to the upper surface of the storage space, changing its spatial dimension. This positioning places the device above the cold air discharge port, where it is not directly exposed when the door is opened, thereby improving outer appearance while maintaining functionality.
3Ease of manufacture
If the deodorizing device is placed above the rear of the storage space, then it can be installed, but deodorization efficiency is reduced because air is circulated at the rear
Solution Approach 1:
The cold air discharge port serves as an intermediary location where the deodorizing device is positioned. By placing the device adjacent to the discharge port on the upper surface, the cold air naturally flows through the deodorizing device, enabling effective deodorization without requiring additional protruding structures into the storage space.
