Abstract
The utility model pertains to the technical field of electromagnetic cooker and discloses a convenient and energy-saving electromagnetic cooker. The electromagnetic cooker comprises a casing (1), a panel, a coil plate (2), and a circuit board (3). The coil plate (2) and the circuit board (3) are fixed inside the casing (1). The panel is provided on the casing (1). A shielding aluminum plate (4) is provided right below the coil of the coil plate (2). According to the utility model, a magnetic conductive metal piece below the coil plate (2) is prevented from generating an eddy current and heating by adding the shielding aluminum plate (4). Even if the electromagnetic cooker is placed on a magnetic conductive metal table, the eddy current and a heating phenomenon do not occur on the metal table. Therefore, use for a user is convenient, electricity is saved, the use efficiency of the electromagnetic cooker is improved and the user cost is reduced.
Description
Technical field
The utility model belongs to the electromagentic furnace technology field, especially relates to a kind of convenience and energy-conservation electromagnetic oven.
Background technology
Electromagnetic oven is to utilize electromagnetic induction principle to convert electrical energy into heat energy.Convert the alternating voltage of 50/60Hz to direct voltage by rectification circuit; Convert direct voltage to high frequency voltage that frequency is 20 ~ 35KHz through control circuit again; The electric current that high speed changes flows through coil and produces the magnetic field that changes at a high speed, in the magnetic line of force in the magnetic field passes through metalware bottom metal body, produces countless little eddy current, makes vessel heating at a high speed voluntarily itself; And then the thing in the heating vessel, reach the effect that the user uses.But the magnetic conductive metal below the coil panel of electromagnetic oven also can produce heat simultaneously; The for example fixedly screw of usefulness or other finding, the circuit board of perhaps traditional electromagnetic oven below coil panel etc., and when electromagnetic oven is placed on the metal desktop of magnetic conduction; This caloric value also can increase; So just brought certain inconvenience, the more important thing is and to cause waste of electric energy, can't bring into play the maximum effect of electromagnetic oven to the user.
The utility model content
In order to solve the deficiency that exists in the above-mentioned prior art, the utility model has designed a kind of convenience and the energy-conservation electromagnetic oven that can avoid electromagnetism to leak.
The concrete scheme of the utility model is: a kind of convenience and energy-conservation electromagnetic oven; Comprise shell (1), panel, coil panel (2), circuit board (3); Wherein coil panel (2), circuit board (3) are fixed in the shell (1); Panel is located on the shell (1), is provided with shielding aluminium sheet (4) under the middle coil of coil panel (2).Avoided the magnetic conductive metal spare generation eddy current of coil panel (2) below to generate heat through increasing shielding aluminium sheet (4); Even electromagnetic oven is placed on the magnetic conductive metal desktop; Can not produce the eddy-current heating phenomenon at the metal desktop yet, convenient for users to use, and saved electric energy; Improve the service efficiency of electromagnetic oven, reduced user's use cost.
For the shield effectiveness of assurance shielding aluminium sheet (4) is good, the diameter at minimum place, the outer of shielding aluminium sheet (4) is greater than the diameter of the outer maximum of the middle coil of coil panel (2), so that shielding aluminium sheet (4) covers coil comprehensively.
The outer contour shape of above-mentioned shielding aluminium sheet (4) and the outer contour shape of coil panel (2) are same or similar, and when assembling install according to the outer contour shape is corresponding, so preferably all be designed to regular circular, so both processing easily was convenient for assembly again.
Above-mentioned shielding aluminium sheet (4) is fixed in the shell (1) through the plastics screw, perhaps on shell (1), is provided with claw chucking shielding aluminium sheet (4), avoids producing unnecessary eddy-current heating, further saves electric energy.
The utility model is compared with existing electromagnetic oven has following beneficial effect: effectively avoided the magnetic conductive metal spare generation eddy current of coil panel (2) below to generate heat through increasing shielding aluminium sheet (4); And can be placed on the metal desktop and to use and can not make the metal desktop produce eddy current and generate heat; Saved the energy; Convenient for users to use, simple in structure, with low cost.
Description of drawings
Fig. 1 is that electromagnetic oven is removed front view behind the panel among the utility model embodiment;
Fig. 2 is the cross-sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As depicted in figs. 1 and 2; A kind of convenience and energy-conservation electromagnetic oven; Comprise shell 1, panel (not shown), coil panel 2, circuit board 3, shielding aluminium sheet 4; Wherein coil panel 2, circuit board 3, shielding aluminium sheet 4 are fixed in the shell 1, shielding aluminium sheet 4 be located at coil in the coil panel 2 under, panel is fixed on the shell 1.
As shown in Figure 1 again, the body shape of coil panel 2 is circular, and the shape of shielding aluminium sheet 4 also be circular, guarantees coaxially during installation, and the diameter of shielding aluminium sheet 4 is greater than the diameter of coil panel 2 main bodys, so that shielding aluminium sheet 4 covering coil panels 2 comprehensively.
Claims (4)
1. convenience and energy-conservation electromagnetic oven; Comprise shell (1), panel, coil panel (2), circuit board (3); Wherein coil panel (2), circuit board (3) are fixed in the shell (1); Panel is located on the shell (1), it is characterized in that: be provided with shielding aluminium sheet (4) under the middle coil of described coil panel (2).
2. convenience according to claim 1 and energy-conservation electromagnetic oven is characterized in that: the diameter at minimum place, the outer of described shielding aluminium sheet (4) is greater than the diameter of the outer maximum of coil in the coil panel (2).
