Magnetic strip for electromagnetic oven

Abstract

The invention relates to a magnetic strip for an electromagnetic oven, which is characterized in that two vertical parts are respectively connected with two ends of a horizontal part through two transition parts, the inner surface of each transition part is in smooth transition with the inner surface of the horizontal part and the inner surface of the corresponding vertical part, and the outer surface of each transition part is in smooth transition with the outer surface of the horizontal part and the outer surface of the corresponding vertical part; the outer surface of the horizontal part isuniformly connected with three reinforcing ribs A along the length direction; two reinforcing ribs B are uniformly connected on the outer surface of the left vertical part along the width direction of the horizontal part, and one end of each reinforcing rib B starts at the upper end of the vertical part, the other end extends through the vertical part and the transition part and is connected withthe reinforcing rib A at the left side; two reinforcing discs C are uniformly connected on the outer surface of the right vertical part along the width direction of the horizontal part, one end of each reinforcing rib C starts at the upper end of the vertical part, and the other end extends through the vertical part and the transition part and is connected with the reinforcing rib A at the rightside. The magnetic strip is large in magnetic flux area at the junction of the horizontal part and the vertical part, high in heating efficiency and not easy to deform.

Description

technical field [0001] The invention relates to, in particular to a magnetic strip for an electromagnetic cooker. Background technique [0002] The coil disk of the induction cooker includes a bracket, a coil built in the bracket, and a magnetic strip arranged outside the bracket. The main function of the magnetic strip is to reduce the magnetic resistance, improve the efficiency and power of the coil disk, and guide the direction of the magnetic force line. Conventional magnetic strips are generally bar-shaped or U-shaped, wherein a U-shaped magnetic strip includes a horizontal portion and a vertical vertical portion connected to an end of the horizontal portion, and the horizontal portion and the vertical portion are integrally formed. This traditional U-shaped magnetic strip has a relatively small magnetic flux area at the connection, resulting in low heating efficiency at the connection. In addition, during the sintering process of the magnetic strip, due to its uneven ...

This traditional U-shaped magnetic strip has a relatively small magnetic flux area at the connection, resulting in low heating efficiency at the connection

In addition, during the sintering process of the magnetic strip, due to its uneven density and thickness, the deformation of the magnetic strip will occur, which will reduce the service life of the magnetic strip
