Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, specifically to an induction cooker with improved heat dissipation. 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 the direct current is converted into high-frequency alternating current exceeding the audio frequency by a high-frequency power conversion device. The 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. Due to electromagnetic induction, a strong eddy current is generated inside the cooking pot. As the eddy current overcomes the internal resistance of the pot, it completes the conversion of electrical energy into heat energy. The resulting Joule heat is the heat source for cooking.

[0003] The pot must be made of iron or alloy steel, whose high magnetic permeability enhances the magnetic field, thereby greatly increasing the eddy electric field and eddy current heat power. Cookware made of other materials, due to their excessively high or low resistivity, will cause abnormal load on the induction cooker, triggering its automatic protection and preventing normal operation. Furthermore, because iron effectively absorbs magnetic fields and has excellent shielding properties, it reduces magnetic radiation significantly, making iron pots safer than cookware made of any other material. Current induction cookers are small in size, and the high-temperature zone during operation affects the overall temperature. Relying solely on the built-in fan for cooling is insufficient and can shorten the lifespan of the internal electronic components. Utility Model Content

[0004] The purpose of this invention is to provide an induction cooker with improved heat dissipation, which solves the problem that current induction cookers are small in size, and the high-temperature zone during operation affects the overall temperature. The problem is that relying solely on the built-in fan for heat dissipation is insufficient to effectively cool the induction cooker, which affects the lifespan of the internal electronic components.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an induction cooker with improved heat dissipation, comprising a cooker body, a support foot fixedly connected to the bottom of the cooker body, a heat absorption hole communicating with the interior of the cooker body on the left side of the cooker body, an air intake port snapped into the interior of the heat absorption hole, an air intake mechanism fixedly connected to the left side of the air intake port, an air outlet provided on the left side of the air intake mechanism, a slot on the left side of the cooker body, a shrinkable rubber strip fixedly connected to the inner wall of the right side of the slot, a crossbar fixedly connected to the left end of the shrinkable rubber strip, and a limit plate fixedly connected to the left end of the crossbar.

[0007] Furthermore, the right side of the limiting plate overlaps with the left side of the suction mechanism.

[0008] Furthermore, a support groove is provided on the left side of the furnace body, and a reinforcing rod is inserted into the inside of the support groove.

[0009] Furthermore, the lower surface of the reinforcing rod is fixedly connected to the upper surface of the suction mechanism.

[0010] Furthermore, the surface of the crossbar is movably connected to the interior of the slot.

[0011] Furthermore, the shrinkable rubber strip has good extensibility and elasticity.

[0012] This invention provides an induction cooker with improved heat dissipation. It has the following beneficial effects:

[0013] This improved heat dissipation induction cooker, through the cooperation of heat absorption holes, air intake ports, air intake mechanisms, air outlets, shrink rubber strips, slots, crossbars, limiting plates, reinforcing rods, and support slots, achieves the goal of adding heat dissipation measures to the induction cooker, improving the heat dissipation effect. At the same time, it limits and supports the heat dissipation measures, increasing the stability of the heat dissipation measures. This solves the problem that current induction cookers are small in size, and the high-temperature zone during operation affects the overall temperature. The problem that relying solely on the built-in fan for heat dissipation is not enough to cool down the induction cooker, which will affect the lifespan of the internal electronic components.

A heat absorption hole 3 communicating with the interior of the cooker body 1 is opened on the left side of the cooker body 1. An air intake 4 is snapped into the heat absorption hole 3. An air intake mechanism 5 is fixedly connected to the left side of the air intake 4. A fan is installed inside the air intake mechanism 5, and its airflow direction is to the left, thereby dissipating the heat inside the cooker body 1 to the outside. A support groove 12 is opened on the left side of the cooker body 1, and an auxiliary device is inserted into the support groove 12.
