1-Fig. 6 describes the panel 100 for electromagnetic oven (scheming not shown) according to the utility model embodiment in detail with reference to the accompanying drawings.
As shown in Figure 1, according to the panel 100 for electromagnetic oven of the utility model embodiment, panel body 10 is comprised.Specifically, the upper surface of panel body 10 is provided with depressed part 20.When on the upper surface that pot body is positioned over panel body 10, gap is formed between the upper surface of bottom of pot body and panel body 10, to reduce the contact area of pot body bottom surface and panel body upper surface, thus the direct contact surface effectively reducing pot body and panel body 10 amasss.It should be noted that, the density of air is much smaller than the density of panel body 10, rise same temperature under the same volume, the heat that the heat of the absorption of air in gap absorbs much smaller than panel body 10, thus can effectively reduce the heat being passed to panel body 10 by pot body.
In correlation technique, the upper surface of the panel body of electromagnetic oven is formed as plane, when pot body is positioned on panel body, the whole bottom of pot body contacts completely with the upper surface of panel body, the high temperature that bottom of pot body produces can be directly delivered on panel body, and then cause the loss of heat on pot body, reduce the efficiency of heating surface and the radiating efficiency of electromagnetic oven; And the high temperature be delivered on panel body can be radiated electromagnetic oven inside further, the operating temperature of each electromagnetic oven intraware (such as IGBT, Qiao Dui, coil panel, electric capacity etc.) is made to increase, be unfavorable for electromagnetic oven heat radiation, and then shorten the life-span of electromagnetic oven.
And according to the panel 100 for electromagnetic oven of the utility model embodiment, by arranging depressed part 20 on the upper surface of panel body 10, make pot between body bottom surface and the upper surface of panel body 10, to be formed with gap, significantly reduce the heat being passed to panel body 10 by pot body thus, also reduce the heat being passed to electromagnetic oven inside by panel body 10 simultaneously, and then improve the efficiency of heating surface and the radiating efficiency of electromagnetic oven, extend the service life of electromagnetic oven.
As shown in Figure 1, use electromagnetic oven for the convenience of the user, the upper surface of panel body 10 is formed with the heating region 40 relative with pot body, heating region 40 normally on panel just to the border circular areas of coil panel, depressed part 20 is located in heating region 40.
Alternatively, depressed part 20 projected area is in the horizontal plane more than or equal to 12cm
2, and maximum cup depth is 0.5-10mm.That is, when panel body 10 horizontal positioned, the area sum of depressed part 20 projection is in the horizontal plane more than or equal to 12cm
2, the depth capacity of depressed part 20 is 0.5-10mm.
In example as Figure 1-Figure 2, depressed part 20 can be formed as one, is arranged on the center of panel heating region 40, and depressed part 20 can be formed as circular, and the diameter of circular depression 20 is 20-280mm.Thus, can make pot between body bottom surface and the upper surface of panel body 10, to form gap, and then reduce the thermal loss of pot body, improve the efficiency of heating surface of electromagnetic oven.
Be understandable that, number for depressed part 20 is not limited to this, such as, in embodiment example as Figure 3-Figure 4, depressed part 20 can be formed as multiple, multiple described depressed part is uniformly distributed and is spacedly arranged on heating region 40, and multiple depressed part 20 is all formed as circular, and the diameter of each depressed part 20 is 1-30mm.Certainly, the shape for depressed part 20 is not limited to circle, can be square or irregularly shaped etc.
In another embodiment, in the example as shown in Fig. 5-Fig. 6, heating region 40 place is provided with an annular recess, and this annular recess is annular depressed part, can certainly be square or polygon depressed part.The internal diameter of annular depressed part can be 20-80mm, and external diameter can be 60-280mm.In addition, also can arrange multiple annular recess, multiple annular recess arranges with one heart and is spaced from each other.
In an embodiment of the present utility model, the thickness of panel body 10 can be 3-12mm.
According to the electromagnetic oven of embodiment of the present utility model, comprise above-mentioned panel 100.
In correlation technique, the upper surface of the panel body 10 of electromagnetic oven is formed as plane, when pot body is positioned on panel body 10, the whole bottom of pot body contacts completely with the upper surface of panel body 10, the high temperature that bottom of pot body produces can be directly delivered on panel body 10, and then cause the loss of heat on pot body, reduce the efficiency of heating surface of electromagnetic oven; And the high temperature be delivered on panel body 10 can be radiated electromagnetic oven inside further, the operating temperature of each electromagnetic oven intraware (such as IGBT, Qiao Dui, coil panel, electric capacity etc.) is made to increase, be unfavorable for electromagnetic oven heat radiation, and then shorten the life-span of electromagnetic oven.
And according to the electromagnetic oven of the utility model embodiment, by arranging depressed part 20 on the upper surface of panel body 10, make pot between body bottom surface and the upper surface of panel body 10, to be formed with gap, decrease both contacts area, significantly reduce the heat being passed to panel body 10 by pot body thus, also reduce the heat being passed to electromagnetic oven inside by panel body 10 simultaneously, and then improve the efficiency of heating surface of electromagnetic oven, extend the service life of electromagnetic oven.
As shown in Figs. 7-8, below with by silica (SiO
2) electromagnetic oven panel made is example, explanation is compared to the electromagnetic oven in correlation technique with according to the heating effect of the electromagnetic oven of an embodiment of the present utility model, be worth understanding, following description is that example illustrates, instead of to concrete restriction of the present utility model.
Thermal conductivity due to air is 0.01-0.04W/mK, and silica SiO
2thermal conductivity be 7.6W/mK, obviously, the thermal conductivity of air is much smaller than the thermal conductivity of panel body.Fig. 7 is thermal efficiency comparison diagram, wherein series 1 represents the electromagnetic oven thermal efficiency curve using prior art panel, series 2 represents the electromagnetic oven thermal efficiency curve of the panel using an embodiment of the present utility model, the panel that electromagnetic oven employs the utility model embodiment can be seen, its thermal efficiency ratio is existing wants high, therefore panel of the present utility model effectively can improve the thermal efficiency of electromagnetic oven; Fig. 8 is electromagnetic oven internal temperature comparison diagram, wherein series 3 represents the internal air temperature traces employing the electromagnetic oven of the panel of prior art, series 4 represents the electromagnetic oven internal air temperature traces of the panel using an embodiment of the present utility model, can see that the temperature rise of the electromagnetic oven of the panel employing the utility model embodiment is obviously low than the temperature rise of the electromagnetic oven of prior art, therefore panel of the present utility model effectively can improve the radiating efficiency of electromagnetic oven.
In sum, by arranging depressed part 20 on the upper surface of panel body 10, make pot between body bottom surface and the upper surface of panel body 10, to be formed with gap, significantly reduce the heat being passed to panel body 10 by pot body thus, also reduce the heat being passed to electromagnetic oven inside by panel body 10 simultaneously, and then improve the efficiency of heating surface of electromagnetic oven, extend the service life of electromagnetic oven.
