Solution Overview
Problem
Existing refrigeration and freezing devices face challenges in heating food efficiently and uniformly, leading to nutrient loss and uneven heating due to the limitations of traditional heating methods, and also struggle with power supply module cooling and dust/dampness issues.
Innovation Solution
A refrigeration and freezing device with an electromagnetic heating system that uses a power supply module located outside the cabinet, employing a heat dissipation fan and strip-shaped air inlet and outlet holes with water retaining ribs to ensure efficient heat dissipation and prevent moisture and dust ingress, while maintaining high space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power supply module is placed inside the cabinet body, then the device structure is compact, but the heating space and storage space are reduced and heat dissipation is difficult
Solution Approach 1:
The power supply module is extracted from the cabinet body and placed in an external accommodation space formed by the accommodation groove and cover plate. This extraction resolves the space conflict by locating the power supply module outside the heating and storage spaces, ensuring both spaces remain relatively large while the device structure remains integrated and compact.
2Productivity
If traditional heating devices are used, then the device structure is simple, but the heating time is long and temperature control is difficult
Solution Approach 1:
The traditional mechanical heating device is replaced with an electromagnetic heating device that uses electromagnetic waves to heat food. This substitution dramatically improves heating efficiency and temperature control while the integrated design keeps the overall device structure relatively simple.
3Duration of action of stationary object
If the power supply module operates without effective cooling, then the device structure is simple, but the service life is reduced and efficiency decreases
Solution Approach 1:
The power supply module performs self-cooling by utilizing the natural airflow generated during device operation. The airflow passes through the accommodation groove and cover plate, providing passive cooling that extends service life without requiring an active cooling system.
4Reliability
If the power supply module is exposed to the environment, then the device structure is simple, but the module is prone to dampness and dust accumulation
Solution Approach 1:
The power supply module is nested within the accommodation space formed by the accommodation groove and cover plate. This nested structure provides protection from dampness and dust while maintaining a compact integrated design without requiring separate protective enclosures.
