Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a silent induction cooker with good heat dissipation effect. Background Art

[0002] During heating, induction cookers need to dissipate heat simultaneously to protect both the components and the cooker. Existing induction cookers primarily rely on small axial-flow fans for cooling, which is not only noisy but also inefficient. Continuous high-power operation can lead to rapid temperature rises, resulting in excessively high temperatures and shortening the cooker's lifespan.

[0003] According to the above, the existing heat dissipation structure of the induction cooker needs to be further improved. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing induction cooker heat dissipation structure and provide a silent induction cooker with good heat dissipation effect. A fan structure is set to suck and dissipate heat. The fan structure adjusts the speed according to temperature changes, thereby controlling the temperature rise and ensuring the service life of the induction cooker. At the same time, components are arranged on the heat dissipation duct. Driven by the fan structure, the heat dissipation duct makes the air flow speed faster, and the heat dissipation effect of the components is better.

[0006] The present invention provides a fan structure for suction and heat dissipation. The fan structure adjusts its speed according to temperature changes, thereby drawing a corresponding amount of airflow to dissipate heat from the induction cooker, thereby controlling temperature rise. When operating at low power, the fan structure rotates at a low speed, resulting in low operating noise. When operating at high power, the fan structure rotates at a high speed, preventing excessive temperature rise.
