Solution Overview
Problem
Existing refrigerators face issues with separate locations for the compressor and evaporator requiring inconvenient repairs, cumbersome manufacturing, reduced storage space due to the heat exchange room, and insulation performance deterioration when the heat exchange room is not in close contact with the storage space.
Innovation Solution
A storehouse design with integrated first and second storage spaces, where the heat exchange device is easily mounted and coupled to the storehouse body, allowing for fluid connection and improved sealing, and can be easily separated for repairs without removing stored items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the compressor and evaporator are placed in separate spaces (machine room and heat exchange room), then the refrigeration cycle components can be independently positioned, but repair becomes inconvenient requiring food removal and complex access procedures
Solution Approach 1:
The patent combines the compressor and evaporator into a single integrated refrigeration cycle component assembly that can be accessed together through one opening. This merging allows both components to be positioned within the same accessible region, eliminating the need to remove food stored in separate machine rooms or heat exchange rooms during repair operations.
2Reliability
If the evaporator is integrally formed inside the refrigerator body and fixed by welding, then structural stability is achieved, but manufacturing becomes cumbersome and defrosting causes temperature increase in storage space
Solution Approach 1:
The patent segments the refrigeration cycle components into a modular assembly that includes the evaporator and compressor as integrated but separable units. This segmentation allows the components to be manufactured independently and assembled together using simplified connection methods instead of complex welding processes, while maintaining structural stability through the integrated design.
3Ease of manufacture
If the heat exchange room is arranged at the rear of the storage space, then the heat exchange device can be positioned, but the width of the rear wall increases and storage space volume decreases
Solution Approach 1:
The patent repositions the heat exchange device and refrigeration cycle components to utilize the vertical dimension and side wall spaces rather than exclusively occupying rear wall space. This dimensional redistribution allows the heat exchange room to be arranged in a three-dimensional configuration that does not increase the rear wall width, thereby preserving maximum storage space volume while maintaining proper heat exchange device positioning.
4Device complexity
If the heat exchange device is combined with the storage main body, then integration is achieved, but if the heat exchange room is not in close contact with the storage main body, insulation performance deteriorates
Solution Approach 1:
The patent employs thermal insulation barriers and sealing structures between the heat exchange room and storage space that maintain effective thermal isolation even when the components are integrated. These flexible insulation elements ensure that the heat exchange room remains thermally isolated from the storage main body, preventing energy loss and maintaining insulation performance despite the integrated configuration.

AI summary
The present invention may include a heat exchanger case that accommodates a first heat exchanger and constitutes at least a portion of a second wall of the second storage space. The heat exchanger case includes a hinge device, and the hinge device may rotate while supported by a hinge holder of the storehouse body so that the heat exchanger case may move in a direction in which the heat exchanger case is in close contact with the storehouse body.
