Refrigerator vegetable room
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerator vegetable rooms experience uneven temperature distribution, leading to dew formation and vegetable decay due to temperature differences, which affects the freshness of stored fruits and vegetables.
Innovation Solution
A metal plate is attached to the case of the refrigerator vegetable room to facilitate heat transfer across multiple surfaces, ensuring uniform temperature distribution, and an insulating material is used to block cool air transfer from the freezing chamber, minimizing temperature differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vegetable room is mounted at an inner portion of the refrigerating chamber, then the vegetable room can be provided as an independent space, but uneven temperature distribution occurs due to cool air from the freezing chamber causing temperature differences between left and right wall portions
Solution Approach 1:
A metal plate is introduced as an intermediary thermal conduction element between the cooling system and the vegetable room air. The metal plate receives cool air from the freezing chamber and distributes it uniformly across the vegetable room, acting as a mediator that transforms localized cooling into uniform temperature distribution.
Solution Approach 2:
The patent replaces complex mechanical temperature distribution systems with a simple thermal conduction-based metal plate. Instead of using multiple fans, ducts, or active control mechanisms, the solution uses passive thermal conduction through a metal plate to achieve uniform temperature distribution.
2Temperature
If the left wall portion of the vegetable room is exposed to cool air from the freezing chamber, then cooling efficiency is improved, but temperature difference between wall portions increases causing dew formation
Solution Approach 1:
The metal plate is divided into multiple regions (first metal plate at the left wall exposed to cool air, second metal plate at the right wall, third metal plate at the rear wall) that locally adapt to different thermal conditions. Each region has specific properties optimized for its location, creating local quality variations that collectively achieve global temperature uniformity.
Solution Approach 2:
The patent converts the harmful effect of cool air causing temperature differences and dew formation into a beneficial uniform cooling system. The metal plate structure transforms the concentrated cool air exposure into distributed uniform cooling across all wall portions, turning the temperature difference problem into a solution.
3Reliability
If the partition wall is formed not to transfer temperature from the freezing chamber, then independent function of each storage chamber is maintained, but temperature uniformity in the vegetable room deteriorates
Solution Approach 1:
The patent solves the temperature uniformity problem by transitioning from a two-dimensional wall-based heat transfer approach to a three-dimensional air circulation system. The metal plates create multiple thermal pathways through the vegetable room space, distributing cool air in three dimensions rather than relying on single-point wall conduction.
