Abstract

The utility model relates to a panel of an induction cooker, wherein, a top surface is a plane. The utility model is characterized in that at least one groove is arranged on the top surface; the groove is distributed on a heating area of the panel; the bottom of the groove is the plane or a curved surface; the depth of the groove ranges from 0.2 to 5 mm; and the periphery shape of groove is of a round or a polygon. As the groove is arranged on the top surface of the panel, the direct contact area on the bottom of a pan is reduced, the heat dissipation of the pan is reduced, and the heating efficiency of the induction cooker is increased by 2 percent; when the pan is put on the top surface, relatively close space is formed, the heating and the temperature measurement is relatively uniform and accurate through air, and the temperature measurement precision is enhanced, thereby leading better cooking effect. The test improves that the temperature measurement precision is increased by about 50 percent.

Description

Electromagnetic oven panel

Technical field

The utility model relates to a kind of electromagnetic oven panel.

Background technology

Electromagnetic oven is to rely on electromagnetic induction principle, and pan is placed on the panel, makes the bottom of a pan produce eddy current under the electromagnetism drum effect of panel below, by the bottom of a pan heating itself food is carried out heating cooking; The most glass-ceramic panels that adopt of panel, one of such panel characteristics is to have good vertical thermal conductivity and poor lateral thermal conductivity, therefore corresponding panel can be assembled a large amount of heat below the pan, can be delivered to electromagnetic oven inside by panel, discharge through the electromagnetic oven fan inside again, so lost the efficiency of heating surface that portion of energy has also just reduced electromagnetic oven, be unfavorable for energy-conservation.

Present electromagnetic oven all is to conduct heat to stove by pan to carry out thermometric, if when running into the pan of wall thickness, it is inhomogeneous that the distortion of pan can cause pan that the heat of stove is transmitted, thereby cause the electromagnetic oven thermometric inaccurate, and function realizes poor effect.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of electromagnetic oven panel is provided, and helps improving the electromagnetic oven thermal efficiency, improves the thermometric reliability.

Technical solutions of the utility model: a kind of electromagnetic oven panel, end face is the plane, it is characterized in that, and end face is provided with at least one groove, and described groove is distributed in the thermal treatment zone of panel.

Groove floor is plane or curved surface.

Depth of groove is 0.2～5mm.

The peripheral shape of groove is circular or is polygon.

The present invention has following advantage:

At first, because the panel end face is provided with groove, reduced the area that directly contacts with the pan bottom, the heat that has reduced pan scatters and disappears, and has improved the efficiency of heating surface about 2% of electromagnetic oven.

Secondly, the groove of panel, right and wrong are penetrating, form airtight relatively space after putting pan, conduct heat and thermometric by air, and relatively evenly accurate, as to have improved electromagnetic oven temperature measurement accuracy makes the culinary art effect better.By verification experimental verification, temperature measurement accuracy has improved about 50%.

The specific embodiment

As shown in Figure 1, the electromagnetic oven panel of prior art, pan are placed on the panel, and the panel end face is the plane.

Shown in Fig. 2,4,5, first embodiment electromagnetic oven panel of the utility model, end face is the plane, end face is provided with a groove, the bottom surface of groove 2 is the plane, groove 2 degree of depth are that 0.2mm is (certainly according to actual electromagnetic stove whole big or small coupling and factor affecting such as panel self material and processing technology, can between 0.2～5mm, choose), the central authorities of the thermal treatment zone of described groove 2 subpanels 1, peripheral shape is a square, the length of side is 50mm, panel wall thickness unanimity, and the described thermal treatment zone is meant the zone of placing pan at electromagnetic oven panel.

Because the end face of panel 1 is provided with groove 2, reduced panel 1 and pan 3 bottom contacts area, the heat that has reduced pan 3 scatters and disappears, and has improved the efficiency of heating surface about 2% of electromagnetic oven.Equally, form airtight relatively space, heat transfer and thermometric are accurate, make the culinary art effect better.By verification experimental verification, temperature measurement accuracy has improved about 50%.

Shown in Fig. 3,6,7, second embodiment electromagnetic oven panel of the utility model, end face is the plane, end face is provided with a groove 2, and groove 2 bottom surfaces are curved surface, and groove 2 degree of depth are 0.5mm, the central authorities of the thermal treatment zone of described groove 2 subpanels 1, peripheral shape is circular, and circular diameter is 50mm, panel wall thickness unanimity.

As shown in Figure 8, the 3rd embodiment electromagnetic oven panel of the utility model is that with the difference of embodiment one the panel wall thickness is different, and promptly the panel bottom surface can also be a plane.

Shown in Fig. 9,10,11, other embodiment electromagnetic oven panels of the utility model mainly are that the quantity and the shape of groove 2 also has multiple variation, what Fig. 9 represented is two grooves, is " day " shape, and what Figure 10 represented is four grooves, be " field " shape, what Figure 11 represented is circular groove structure.
