Description

Technical Field

[0001] This utility model relates to the field of electromagnetic induction heating technology, and in particular to an outdoor electromagnetic induction heating device powered by a photovoltaic inverter. Background Technology

[0002] Induction cookers can raise the temperature of a pot bottom to over 300 degrees Celsius within 15 seconds, much faster than oil or gas stoves, significantly saving cooking time and increasing the speed of food preparation. The principle of an induction cooker is magnetic field induction eddy current heating, which uses an electric current passing through a coil to generate a magnetic field. When the magnetic lines of force pass through the bottom of an iron pot, they are cut, generating countless small eddy currents. This causes the iron atoms in the pot to rotate at high speed and generate heat through collision and friction, directly heating the food inside the pot. Compared to traditional gas stove combustion heating, electromagnetic induction heating has the advantages of being green and environmentally friendly, and it also has stronger stability in extreme environments, such as windy conditions.

[0003] Currently, induction cookers mainly regulate their output power directly through AC power from the power grid, meaning they are primarily used in homes and shopping malls where the power grid covers the area. However, when picnicking outdoors, portable DC power supplies cannot power the induction cooker due to DC and voltage limitations, making it impossible to cook green and environmentally friendly meals. Furthermore, they cannot be used for extended outdoor camping trips. Utility Model Content

[0004] The purpose of this invention is to solve the problem that portable DC power supplies cannot power induction cookers during outdoor picnics due to DC and voltage limitations, thus hindering green and environmentally friendly picnic cooking. Therefore, this invention proposes an outdoor electromagnetic induction heating device powered by a photovoltaic inverter.

The photovoltaic power generation module is used to convert solar energy into electrical energy and store the electrical energy in the storage battery via the first transmission line. The storage battery is used to store the DC power output by the photovoltaic power generation module.
