technical field

The utility model belongs to the technical field of cooking of household appliances, in particular to a coil pan cover with a magnetizer and an electric rice cooker equipped with the coil pan cover.

Background technique

At present, electric rice cookers generally have two heating methods, one is electric heating tube heating, and the other is electromagnetic heating, or magnetic induction heating. The electromagnetic of the magnetic induction heating is generated by the energized coil, and the coil is fixed on the outer wall surface of the coil disc support. Because of the fast heating speed and uniform heating of magnetic induction heating, the cooked rice is better, so it is more and more favored by consumers.

In the electromagnetic heating rice cooker products on the market, the coil plate assembly is generally composed of a coil plate seat, a coil, a magnetic strip and a magnetic strip seat. In order to improve the efficiency of electromagnetic induction heating, the coil disk assembly needs to add magnetizers on the bottom and side of the coil. The magnetizers are generally fixed on the installation position of the coil disk base, fixed by glue or added with brackets and screws, and the assembly is cumbersome. The production efficiency is low and the appearance is complicated.

Utility model content

The utility model is proposed in order to overcome the shortcomings in the prior art, and its purpose is to provide a coil disk cover with a magnetizer.

The technical scheme of the utility model is:

A coil disk cover with a magnetizer, the coil disk cover includes a cover body and a magnetizer arranged in the cover body; the magnetizer is composed of at least two groups of magnetically conductive strips; the magnetically conductive strips are strip-shaped, and They are uniformly distributed along the circumference, arranged radially along the bottom of the cover body, and intersect with the direction of the coil.

The cover body is a hollow cylinder with an open upper end, the bottom protrudes downward to form an arc surface, a through hole is arranged in the center of the bottom, and the wall of the through hole extends upward to form a convex ring.

A duckbill-shaped protrusion is formed on the bottom of the cover where the heat dissipation holes are located.

The magnetic conductor is fixed on the inner bottom or the inner wall of the cover by any one of inlay, glue, buckle connection and screw connection.

The magnetic conductive strip is a one-stage or multi-stage structure.

An electric rice cooker equipped with a coil disk cover, the electric rice cooker is provided with a coil disk assembly inside, the coil disk assembly includes a coil disk seat, a coil, a temperature controller and a coil disk cover, the coil disk seat is installed in the middle of the electric rice cooker, and the inner pot Directly below the coil, the coil is wound between the ribs on the back of the coil base, and the coil cover is fixed to the lower part of the coil base through buckles or screws. The coil cover is provided with a magnetic conductor.

The beneficial effects of the utility model are:

The utility model provides a coil disk cover provided with a magnetizer, which can concentrate the electromagnetic field generated by the coil, improve heating efficiency, has simple structure, low cost, quick and convenient assembly, reliable use and strong applicability.

detailed description

A coil disc cover with a magnetizer and an electric cooker equipped with the coil disc cover of the utility model will be described in detail below in conjunction with the accompanying drawings and embodiments of the specification:

As shown in Figures 1 and 2, a coil disk cover with a magnetizer, the coil disk cover 4 includes a cover body 7 and a magnetizer 6 arranged in the cover body 7; the upper end surface of the cover body 7 is provided with a plurality of The buckle 9 and the slot 10, the buckle 9 and the slot 10 are matched with the coil base, and the bottom is provided with a cooling hole 11;

The cover body 7 is a hollow cylinder with an open upper end, the bottom of which protrudes downward to form an arc surface, and is provided with cooling holes 11;

The cover body 7 is fixed on the lower part of the coil disk seat by buckling around the circle or fastened on the coil disk seat by screws.

A duckbill-shaped protrusion 14 is formed at the bottom of the cover body 7 where the cooling holes 11 are located.

The magnetic conductor 6 is fixed on the inner bottom or the inner side wall of the cover body 7 by any one of inlay, glue, buckle connection and screw connection.

The magnetic strips 8 are elongated, uniformly distributed along the circumference, radially arranged along the bottom of the cover body 7 , and intersect with the direction of the coil 2 .

The magnetic conductive strip 8 is a one-stage or multi-stage structure.

The magnetic strip 8 is made of materials such as magnetically permeable metal and ferrite.

As shown in Figures 3 and 4, an electric rice cooker equipped with a coil disk cover, the inside of the electric cooker is provided with a coil disk assembly, and the coil disk assembly includes a coil disk base 1, a coil 2, a temperature controller 3 and a coil disk cover 4.
