Refrigerator including a drawer supporter having a cold air discharge port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators face challenges in maximizing storage space volume due to the placement of evaporators and cold air discharge ducts, which reduces the internal capacity and increases material costs for refrigerant tubes.
Innovation Solution
A refrigerator design featuring a drawer supporter with an inner passage for cold air flow and multiple discharge ports that distribute cold air evenly, minimizing the need for additional ducts and allowing for a more compact cooling module setup, thereby maximizing storage space depth and reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If evaporator and cold air discharge duct are disposed together in the inner case, then cooling function is achieved, but storage space volume is reduced
Solution Approach 1:
The drawer supporter is merged with the cold air discharge duct function by forming an inner passage within the drawer supporter structure. This integration eliminates the need for a separate cold air discharge duct, allowing cold air to flow through the drawer supporter itself and be discharged through cold air discharge ports, thereby maximizing storage space while maintaining cooling functionality.
Solution Approach 2:
The drawer supporter serves multiple functions: it supports the drawer structure and simultaneously acts as a cold air discharge duct with inner passage and cold air discharge ports. This multi-functionality reduces the number of separate components needed, increasing storage space volume while achieving effective cold air distribution.
2Temperature
If evaporator is disposed between cold air discharge duct and inner wall, then cooling efficiency is improved, but storage space depth is reduced
Solution Approach 1:
The evaporator is disposed in the width direction rather than the front-rear direction, allowing cold air to be discharged in opposite directions (left and right) through the drawer supporter. This dimensional change enables the evaporator to be positioned without reducing storage space depth, as the cooling function is achieved through lateral heat exchange rather than longitudinal placement.
3Temperature
If separate cold air discharge duct is installed, then cold air distribution is achieved, but device complexity and material cost increase
Solution Approach 1:
The cold air discharge duct function is merged into the drawer supporter structure by forming an inner passage within it. This eliminates the need for a separate cold air discharge duct component, reducing device complexity and material costs while still achieving effective cold air distribution through the integrated structure.
Solution Approach 2:
The drawer supporter serves as both a structural support element and a cold air discharge duct with integrated inner passage and discharge ports. This multi-functionality eliminates the need for separate ducting components, simplifying the overall device structure and reducing material requirements.

AI summary
A refrigerator may include a body formed with a storage space and a cooling module accommodating space; a cooling module disposed in the cooling module accommodating space and having a heat absorption part and a heat radiating part; a drawer supporter disposed inside the storage space; and a drawer supported by the drawer supporter, and the drawer supporter is formed with an inner passage through which cold air flowing from the heat absorption part passes, and the drawer supporter is formed with a plurality of cold air discharge ports through which cold air of the inner passage is discharged in an opposite direction. Therefore, it is possible to maximize the depth of the storage space in the front-rear direction while minimizing the number of parts, and cool the entire storage space evenly.
