Spiral shielding mechanism of induction cooker

Abstract

The invention provides a spiral shielding mechanism of an induction cooker. The spiral shielding mechanism comprises a protection frame, a metal coil, a lead plate, aluminum plates, dovetail sliding blocks, dovetail grooves, a metal plate and an electromagnet. The protection frame is arranged at the middle position of the lower end face of a shell. The metal coil is mounted at the middle positionof the upper end face of the lead plate. The lead plate is mounted at the middle position of the lower end face in the protection frame. One aluminum plate is mounted on the left end face in the protection frame. By means of the design, the electromagnetic protection function is achieved, and the electromagnetic shielding effect is good. The dovetail sliding blocks are fixed to the upper end faceof the protection frame and assembled in the dovetail grooves, the dovetail grooves are formed in the lower end face of the shell, the metal plate is mounted on the upper end faces of the dovetail sliding blocks, and the electromagnet is mounted on the upper end faces in the dovetail grooves. By means of the design, the fast demounting and mounting function of a shielding assembly is achieved. Thespiral shielding mechanism is reasonable in structure, complete in function, good in shielding effect, high in practicality and high in reliability.

Description

technical field [0001] The invention relates to a spiral shielding mechanism for an electromagnetic oven, which belongs to the technical field of household appliances. Background technique [0002] Induction cooker is also known as induction cooker. In 1957, the first household induction cooker was born in Germany. In 1972, the United States began to produce induction cookers, and in the early 1980s, induction cookers began to sell well in Europe, America and Japan. The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the use of alternating current to pass through the coil to generate an alternating magnetic field with a constantly changing direction, and an eddy current will appear inside the conductor in the alternating magnetic field (the reason can be referred to Faraday's law of electromagnetic induction). It is caused by the vortex electric field pushing the carrier in the conductor (electrons in the pot are definitely not iro...
