Refrigerator with a divider within the machinery room
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators have a freezing chamber located at a low position, reducing storage volume and convenience due to the need to leave space for the compressor chamber, leading to a specially shaped freezing chamber that is inconvenient for users, especially in terms of access and item placement.
Innovation Solution
A refrigerator design where the cooling chamber is positioned at the bottom, allowing the freezing chamber to be raised and rectangular in shape, with a divider separating the bottom air inlet and outlet to improve airflow and reduce noise from the heat dissipation fan, and is stably fixed using a fan fixing frame and evaporating dish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the freezing chamber is located at the lower part of the refrigerator to accommodate the compressor chamber, then the compressor can be installed, but the freezing chamber depth is limited and its shape becomes specially shaped, reducing storage efficiency and user convenience
Solution Approach 1:
The patent divides the lower space into two separate chambers: a cooling chamber at the very bottom and a compressor chamber above it. The freezing chamber is then positioned above the cooling chamber, creating a segmented vertical arrangement that allows the freezing chamber to have full depth and rectangular shape without being constrained by compressor space requirements.
Solution Approach 2:
The patent reorganizes the vertical stacking order of components, placing the cooling chamber below the freezing chamber rather than having the compressor directly below the freezing chamber. This dimensional reorganization allows the freezing chamber to extend to the bottom of the refrigerator cavity, maximizing its depth and storage volume while maintaining proper compressor placement.
2Productivity
If the bottom air inlet and bottom air outlet are not separated, then the structure is simpler, but external air entering the condenser and heat dissipation air discharged from the compressor cross each other, reducing heat dissipation efficiency
Solution Approach 1:
The patent introduces a divider that segments the bottom space into two separate airflow paths: one for air entering the condenser through the bottom air inlet, and another for hot air discharged from the compressor through the bottom air outlet. This segmentation prevents the crossing of airflows and ensures efficient heat dissipation while maintaining relatively simple structure.
3Object-affected harmful factors
If the heat dissipation fan is installed without vibration isolation, then the structure is simpler, but vibration noise is generated during operation
Solution Approach 1:
The patent introduces a vibration isolation member as an intermediary component between the heat dissipation fan and the compressor chamber. This intermediary element absorbs and dampens vibrations from the heat dissipation fan, preventing noise generation while adding minimal structural complexity.
4Reliability
If the divider is not stably fixed, then the assembly is easier, but the divider cannot effectively separate the airflows and maintain structural integrity
Solution Approach 1:
The patent combines the divider with the cooling chamber structure, making them an integrated assembly. This merging ensures that the divider is stably fixed and effectively separates the airflows while simplifying the manufacturing process, as the divider and cooling chamber can be produced as a single piece or pre-assembled unit.

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
Implementation Method 2
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
Implementation Method 3
sequentially flow through the condenser and the compressor, and finally flow out from the bottom air outlet

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.
