Abstract

The utility model discloses a kind of heating devices of electromagnetic induction heating, including drum and the coil being mounted on drum, ferrite is inlaid on drum, ferrite is made of five independent parts of a vertical magnetic stripe and four lateral magnetic stripes, there are magnetic gaps between this five independent parts, staggered magnetic field is formed at the center of coil, make cookware center non-blind area, the temperature at cookware center is higher than lip temperature and relatively evenly heats from center to outer edge, realizes the bottom of a pan heating close to 90% or more of open firing effect.

Description

A kind of heating device of electromagnetic induction heating
Technical field
The utility model relates to a kind of electromagnetic oven, especially a kind of coil panel of electromagnetic oven.
Background technique
The patent document of Publication No. " CN207118006U " discloses " a kind of whole district's induction heating apparatus ", and the device is logical It crosses and ferrite is set on coil panel to realize that homogeneous heating, the effect of center non-blind area improve heating efficiency, but its really Ferrite is an entirety, is made of vertical section and horizontal segment, and vertical section and horizontal segment are in T shape (referring to specification the 0021st Section, Fig. 3), the ferrite of this structure is in following disadvantage:First is that ferrite is an entirety, the magnetic formed on the ferrite Field is uniformly distributed formula, still has a magnetic field blind spot at the center of vertical section, second is that being directed to the product of different size, needs The ferrite of different size (size) is customized, ferritic versatility is poor, causes the production cost of product higher.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of center non-blind area, realizes that the bottom of a pan is more nearly The heating device of the electromagnetic induction heating of open firing effect.
Technical solution adopted by the utility model to solve its technical problems is:
A kind of heating device of electromagnetic induction heating, including drum and the coil being mounted on the drum, the drum On be inlaid with ferrite, the ferrite includes a vertical magnetic stripe and four transverse direction magnetic stripes, and the drum is provided with through-hole, institute It states vertical magnetic stripe to inlay in the through hole, is higher by the drum at the top of the vertical magnetic stripe;Described four lateral magnetic stripe positions In being mutually 90 degree of arrangements on same plane, the vertical magnetic stripe is vertical with the lateral magnetic stripe.
The bottom of the drum is provided with cross groove, and described four lateral magnetic stripes are embedded in described cross recessed In slot.
The lower end of the vertical magnetic stripe is directly contacted with all or part of lateral magnetic stripe.
The coil turn of the hub of a spool is greater than the coil turn of periphery.
The utility model has the beneficial effects that:The ferrite of the utility model is by a vertical magnetic stripe and four lateral magnetic stripes Five independent parts are constituted, and there are magnetic gaps between this five independent parts, and staggered magnetic field is formed at the center of coil, Make cookware center non-blind area, the temperature at cookware center is higher than lip temperature and relatively evenly heats from center to outer edge, real It heats close to 90% or more of open firing effect in the existing the bottom of a pan.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the cross-sectional view of the utility model;
Fig. 2 is the structural schematic diagram of the utility model;
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, a kind of heating device of electromagnetic induction heating, including drum 1 and be mounted on the drum 1 Coil 2, specifically, the drum 1 is provided with several fixture blocks 7, and card slot 8, institute are formed between the two neighboring fixture block 7 Coil 2 is stated to be wrapped in the card slot 8.
Ferrite is inlaid on the drum 1, the ferrite includes a vertical magnetic stripe 3 and four lateral magnetic stripes 4, institute It states drum 1 and is provided with through-hole 5, the vertical magnetic stripe 3 is embedded in the through-hole 5, and the top of the vertical magnetic stripe 3 is higher by described Drum 1;Described four lateral magnetic stripes 4 are in the same plane to be mutually 90 degree of arrangements, the vertical magnetic stripe 3 and the lateral magnetic stripe 4 is vertical.
The bottom of the drum 1 is provided with cross groove 6, and described four lateral magnetic stripes 4 are embedded in described cross Groove 6 in.
The lower end of the vertical magnetic stripe 3 is directly contacted with all or part of lateral magnetic stripe 4, for four lateral magnetic stripes 4 Arrangement mode there are two types of, the first is that one end of described four lateral magnetic stripes 4 is drawn close and vertically the central symmetry of magnetic stripe 3 is arranged Column form a vacancy between four lateral magnetic stripes 4, correct and be inserted into the vacancy under vertical magnetic stripe 3;It is for second One end of first lateral magnetic stripe and Article 2 transverse direction magnetic stripe is drawn close to be arranged in "-" type, and Article 3 transverse direction magnetic stripe and Article 4 are horizontal Seam crossing to one end of magnetic stripe along first lateral magnetic stripe and Article 2 transverse direction magnetic stripe is symmetrically arranged, and the lower end of vertical magnetic stripe is supported In the binding site of four lateral magnetic stripes.
The coil turn at 2 center of coil be greater than periphery coil turn, i.e., the arrangement density of coil turn from center to Outer uniformly to reduce, this arrangement mode is capable of forming stronger vortex, improves heating efficiency.
The ferrite of the utility model is made of five independent parts of a vertical magnetic stripe and four lateral magnetic stripes, a side Face, there are magnetic gaps between this five independent parts, form staggered magnetic field at the center of coil, make cookware center without blind Area, the temperature at cookware center are higher than lip temperature and relatively evenly heat from center to outer edge, realize that the bottom of a pan heating is close On the other hand 90% or more of open firing effect for the product of different size, only needs to change the vertical magnetic stripe of different height , and lateral magnetic stripe can then be common to the product of different size, can be effectively reduced production cost.
Above embodiment cannot limit the protection scope of the invention, and the personnel of professional skill field are not departing from In the case where the invention general idea, the impartial modification and variation done still fall within the range that the invention is covered Within.
