Refrigerator with divider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional refrigerators have a freezing chamber located at a low position, reducing storage volume and convenience due to the need to accommodate a compressor chamber, leading to inconvenient access and inefficient storage layout.
Innovation Solution
The refrigerator design includes a cooling chamber at the bottom and a freezing chamber above, with a divider separating the bottom air inlet and outlet to improve access and storage efficiency, and fixes the divider to the fan fixing frame, evaporating dish, and supporting plate for stability and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the freezing chamber is located at a lower part to accommodate the compressor chamber, then the compressor chamber can be arranged behind the freezing chamber, but the depth of the freezing chamber is limited and user access becomes inconvenient
Solution Approach 1:
The invention divides the bottom space into separate functional zones using a divider. The first bottom space accommodates the compressor chamber while the second bottom space forms part of the freezing chamber, allowing independent optimization of each zone's function and dimensions.
Solution Approach 2:
The invention changes the spatial arrangement by introducing a vertical divider that creates distinct first and second bottom spaces. This dimensional separation allows the compressor chamber to be positioned in the first bottom space while the freezing chamber extends into the second bottom space, increasing the freezing chamber's effective depth and improving user access.
2Productivity
If the bottom air inlet and bottom air outlet are not completely separated, then the structure is simpler, but external air entering the condenser and heat dissipation air discharged from the compressor cross each other reducing efficiency
Solution Approach 1:
The divider completely separates the bottom air inlet and bottom air outlet into different zones, preventing cross-contamination of air flows. This segmentation ensures that external air entering through the bottom air inlet does not mix with heat dissipation air discharged through the bottom air outlet, maintaining high heat dissipation efficiency.
Solution Approach 2:
The divider extracts and isolates the air flow paths by creating distinct first and second bottom spaces. This extraction of air flow separation functionality from the overall structure allows independent optimization of air inlet and outlet paths without interfering with each other.
3Reliability
If the divider is not fixed securely, then the structure is simpler and easier to assemble, but the divider becomes unstable and noise from heat dissipation fan vibration increases
Solution Approach 1:
The divider is merged with the supporting plate through integrated fixing structures. The supporting plate provides a stable base that combines multiple fixing functions, securing the divider firmly in position while reducing the need for separate fixing components and simplifying the overall assembly.
Solution Approach 2:
Instead of adding complex external fixing mechanisms to stabilize the divider, the invention inverts the approach by making the supporting plate itself the fixing element. The supporting plate incorporates fixing structures that directly secure the divider, transforming the base support function into a stabilization mechanism.

Function Achieved in This Case
This design raises the freezing chamber, improves user access, enhances storage efficiency by allowing spread layout, and reduces noise from the heat dissipation fan's vibration.
Implementation Method 1
a heat dissipation fan and a condenser are sequentially arranged; and a divider configured to completely separate the bottom air inlet from the bottom air outlet to allow external air to enter the compressor chamber via the bottom air inlet located at one transverse side of the divider under the action of the heat dissipation fan, sequentially flow through the condenser and the compressor

AI summary
Provided is a refrigerator (10), including: a cabinet (100) in which a cooling chamber (200) located at a lower side and at least one storage compartment located above the cooling chamber (200) are defined, a bottom air inlet (110a) and a bottom air outlet (110b) being provided in a bottom of the cabinet (100) in a transverse direction at an interval; a compressor chamber (300) arranged behind the cooling chamber (200), in which a compressor (104), a heat dissipation fan (106) and a condenser (105) are sequentially arranged; and a divider (117) configured to completely isolate the bottom air inlet (110a) from the bottom air outlet (110b), such that external air entering the condenser (105) and heat dissipation air discharged from the compressor (104) are not crossed. In the refrigerator (10), the freezing chamber (132) is raised, a user has no need to bend down much to access to the freezing chamber (132), and the use experience is improved. In addition, by the divider (117), the bottom air inlet (110a) and the bottom air outlet (110b) are completely separated, so that the external air entering the condenser (105) and the heat dissipation air discharged from the compressor (104) are not crossed.
