Refrigerator having drawer type door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator deodorizer installations are complex, occupy valuable storage space, and do not effectively circulate cool air to remove odors from all compartments, leading to incomplete odor removal and reduced space utilization.
Innovation Solution
A refrigerator design with a deodorizing case integrated into the drawer, where the deodorizing member is positioned on the inner surface of the storage room and the lower end part is in the cool air circulating flow path, minimizing installation space and enhancing odor removal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the deodorizing unit and deodorizing case are mounted in the door, storage space, or storage room in a complicated assembly structure, then the deodorizer can be installed, but the number of parts increases and assembly time becomes longer
Solution Approach 1:
The deodorizing case is integrated directly into the drawer structure, merging the deodorizing function with the storage compartment. This eliminates the need for separate deodorizing units and complex assembly structures, while maintaining effective odor removal capability.
Solution Approach 2:
The drawer structure serves multiple functions: it provides storage space and simultaneously houses the deodorizing case. This multi-functional design reduces the number of separate components needed while maintaining both storage and deodorizing effectiveness.
2Reliability
If the deodorizing unit and deodorizing case protrude from the wall surface, then the deodorizer can be installed, but the storage room space is occupied and space utilization decreases
Solution Approach 1:
The deodorizing case is nested within the drawer structure rather than protruding outward. This nested design allows the deodorizing function to be incorporated into the existing drawer volume without encroaching on the storage room space, maximizing space utilization.
Solution Approach 2:
The deodorizing case is positioned in the lower portion of the drawer structure, utilizing vertical space that would otherwise be unused. This dimensional arrangement allows deodorizer installation without reducing the horizontal storage capacity of the drawer.
3Ease of manufacture
If the deodorizer is installed in the inner part of one storage chamber, then the deodorizer can be mounted, but cool air with odor is circulated to other storage chambers and odor diffuses
Solution Approach 1:
The deodorizing function is extracted from the enclosed storage chamber environment and positioned in the drawer where it can directly interact with cool air flow. This extraction allows the deodorizer to treat air before it circulates to other chambers, preventing odor diffusion rather than treating it after circulation.
Solution Approach 2:
The drawer structure acts as an intermediary between the storage chamber and other refrigerator compartments. By placing the deodorizer in this intermediate position, it can filter and treat the cool air before it reaches other storage chambers, blocking odor diffusion at the source.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design improves deodorizing performance by ensuring direct contact between cool air and the deodorizing member, reduces storage space occupation, and allows for easy installation and replacement of the deodorizing member, while preventing it from deviating or being damaged.
Implementation Method 1
a deodorizer is mounted in the deodorizing case by being received thereinto, wherein the deodorizer removes an odor of the storage chamber
Implementation Method 2
the lower end part is provided in cool air circulating flow path
