Problems solved by technology

[0004] Since the circuit board integrates the circuit in the electromagnetic heating equipment, the power adjustment potentiometer is directly installed on the circuit board in the existing electromagnetic heating equipment to adjust the resistance in the circuit, and the test tool is used to debug before installation. Check the power of the electromagnetic heating equipment, and then install the whole machine, but there will still be a certain power deviation due to the difference in the inductance of the coils and the distance between the coils; or install the whole machine first, cover the shell, and not screw , when the power does not meet the requirements of use, open the shell for adjustment, until the power meets the requirements and then fix it with screws, which is extremely inconvenient to operate

Abstract

The invention relates to an electromagnetic heating device which comprises a shell, a coil, a circuit board and a potentiometer, wherein the circuit board and the coil are fixed in the shell, and is characterized in that the potentiometer is fixedly arranged in the shell in a separated mode from the circuit board, and the potentiometer and the circuit board are electrically connected through a conductive piece. a debugging hole penetrating through the shell is formed in the side face of the shell, and the potentiometer is adjacent to the debugging hole. When the power of the electromagnetic heating device does not meet the use requirements, and a tool can be directly used for extending into the shell from the debugging hole to adjust the potentiometer, the shell is not required to be opened or the whole machine does not have to be turned over. Horizontal operation is achieved, simplicity and convenience are achieved, and adjustment is easy.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic heating, and in particular relates to electromagnetic heating equipment. Background technique [0002] The electromagnetic heating equipment currently on the market includes a casing, a coil disk, a circuit board and a potentiometer. The coil disk and the circuit board are all fixed in the casing, and the potentiometer is fixed on the circuit board. Among them, the coil disk is one of the important devices to complete the LC oscillation. It is a device that stores and releases electric energy, and a key device that completes the conversion of electric energy into magnetic field energy. Electronic components such as integrated circuits and resistors and capacitors cannot function as a single individual. Only when there is a foothold on the circuit board and there are guides to connect them can they function in this whole; the potentiometer is a An adjustable electronic component is a type ...
