Refrigerator with improved evaporator installation structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators have evaporators located at the rear part of the bottommost storage space, which reduces the front-rear direction volume of the storage space, limits its depth, and makes it inconvenient to store large or difficult-to-separate items.
Innovation Solution
The refrigerator features an evaporator placed on the bottom wall of the storage liner, with limit structures at the front and rear to secure its position, allowing for a cooling space that increases the storage space height and improves user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the evaporator is located at the rear part of the bottommost storage space, then the evaporator can be installed in a conventional position, but the front-rear direction volume of the storage space is reduced and the depth is limited
Solution Approach 1:
The evaporator installation position is changed from the rear part of the storage space to the bottom wall of the storage liner, utilizing the vertical dimension instead of the horizontal rear space. This dimensional shift allows the storage space to extend fully in the front-rear direction while the evaporator occupies the bottom area, thus increasing storage volume without compromising evaporator installation feasibility
2Ease of manufacture
If the evaporator is located at the rear part of the bottommost storage space, then the evaporator can be installed conventionally, but the storage space depth is limited and it becomes inconvenient to place large items
Solution Approach 1:
By relocating the evaporator to the bottom wall of the storage liner, the horizontal depth of the storage space is maximized. This allows large items to be placed conveniently in the storage space without being blocked by the evaporator positioned at the rear, thereby improving ease of operation while maintaining simple evaporator installation through the bottom wall mounting structure with limit structures
3Volume of moving object
If the evaporator is placed on the bottom wall with limit structures, then the storage space depth and volume are improved, but the evaporator installation structure becomes more complex
Solution Approach 1:
The limit structures are integrally formed with the storage liner, merging the evaporator positioning function into the existing storage liner structure. This eliminates the need for separate positioning components and reduces installation complexity while still achieving the goal of maximizing storage space volume through bottom wall evaporator placement
