Description

Technical Field

[0001] This invention relates to the field of induction cooker technology, specifically to an induction cooker based on aerodynamic cooling. Background Technology

[0002] The principle of an induction cooker is electromagnetic induction. Alternating current passing through a coil generates an alternating magnetic field with constantly changing direction. Eddy currents will appear inside a conductor placed in this alternating magnetic field (the reason can be found in Faraday's law of electromagnetic induction). This is caused by the eddy current driving the movement of charge carriers in the conductor (electrons, not iron atoms, in the pot). The Joule heating effect of the eddy currents heats the conductor, thus achieving heating. The cooktop of an induction cooker is a heat-resistant ceramic plate. Alternating current passing through a coil beneath the ceramic plate generates a magnetic field. When the magnetic lines of force pass through the bottom of iron or stainless steel pots, eddy currents are generated, causing the bottom of the pot to heat up rapidly, thus heating the food. The cooktop is a high-strength, impact-resistant ceramic plate (crystal glass). Underneath the cooktop is a high-frequency induction heating coil (excitation coil), a high-frequency power conversion device, and a corresponding control system. A flat-bottomed cooking pot is placed on top of the cooktop. Its working process is as follows: Alternating current is converted into direct current by a rectifier, and then converted into high-frequency alternating current exceeding the audio frequency by a high-frequency power conversion device. This high-frequency alternating current is applied to a flat, hollow, spiral-shaped induction heating coil, thereby generating a high-frequency alternating magnetic field. The magnetic lines of force penetrate the ceramic plate of the stove and act on the metal pot. Strong eddy currents are generated inside the cooking pot due to electromagnetic induction. As these eddy currents overcome the internal resistance of the pot, they complete the conversion of electrical energy into heat energy. The resulting Joule heat is the heat source for cooking. Currently, induction cookers based on aerodynamic cooling have cooling components that are difficult to disassemble, making maintenance of these components inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an induction cooker based on aerodynamic cooling, which solves the problem that the cooling components of current aerodynamic cooling induction cookers are not easy to disassemble, thus making it inconvenient to repair the cooling components.
