Embodiment 1

[0039] This embodiment provides an assembly structure of the magnetic strip 2 and the coil 1, such as Figure 1-Figure 5 shown, including:

[0040] Coil 1, the coil 1 includes a wire-dense area 11 and a wire-loose area; specifically, the coil 1 itself can be a disk-shaped structure, or can be in other shapes, such as a rectangular arrangement. The coil 1 is provided with an incoming line interface and an outgoing line interface, the current flows into the coil 1 through the incoming line interface, and flows out of the coil 1 through the outgoing line interface;

[0041] The magnetic strip 2 is detachably arranged on the coil 1, the magnetic strip 2 has a magnetic strip strengthening area 22 corresponding to the wire dense area 11, and a magnetic strip 2 corresponding to the wire loose area zone of weakening.

[0042] By setting the magnetic strip strengthening area 22, the wire dense area 11 on the coil 1 can obtain more magnetic flux density, and at the same time, because ...

Embodiment 2

[0054] This embodiment provides a cooking device, including the assembly structure of the magnetic strip and the coil provided in Embodiment 1, and a pot body. The coil itself is arranged below the pot body and can support the pot body in a pocket shape.

[0055] In this embodiment, the cooking device may be an electrical device such as an electric pressure cooker that requires the cooperation of a coil and a magnetic strip for heating. As a preferred embodiment, the cooking device is an electric rice cooker.

[0056] In the cooking equipment provided in this embodiment, since the wire-intensive area on the coil 1 is correspondingly arranged in the magnetic strip reinforcement area, more magnetic flux density can be obtained at the wire-intensive area, thereby making the pot body have a larger Magnetic flux, so as to achieve better heating effect.

Abstract

The invention provides a magnetic stripe and coil assembly structure and cooking equipment, and the structure comprises a coil which comprises a wire dense region and a wire loose region; and a magnetic strip which is detachably arranged on the coil, and is provided with a magnetic strip reinforcing area corresponding to the wire dense area and a magnetic strip weakening area corresponding to thewire loose area. According to the invention, by arranging the magnetic stripe reinforcing area, the wire dense area on the coil can obtain higher magnetic flux density, and meanwhile, as the coil in the corresponding area is denser, larger magnetic flux can be generated, so that the coil dense area has larger magnetic flux, and a better heating effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electric rice cookers, in particular to an assembly structure of a magnetic strip and a coil. Background technique [0002] For an electric rice cooker, it is usually heated by electromagnetic induction between the pot body and the coil. The working principle is that after the current passes through the coil, an alternating magnetic field is generated around the coil wire. When a magnetic metal pan is placed on the stove surface, the magnetic force line passes through the pan body, generating eddy current, forming eddy current heat to heat the food in the pan. [0003] Existing rice cookers all add magnetic strips under the coils. The magnetic strips have high magnetic permeability and can gather the magnetic field lines diverging from the coils to increase the magnetic field strength acting on the pot body, thereby increasing the heating efficiency. However, the electric rice cooker in the prior art sti...
