In this embodiment, the oven panel 100 is used to support the cooker 900, so that the cooker 900 can be stably and reliably heated by the heating assembly in the oven body. The projection area of the cooker 900 on the oven panel 100 is a first area a, the first conductive electrode 210 is arranged on the oven panel 100, and at least part of the projection of the first conductive electrode 210 on the oven panel 100 is positioned in the first area a, so that in the direction perpendicular to the oven panel 100, the first conductive electrode 210 and the cooker 900 have at least a partial overlapping area, when the cooker 900 is close to or far from the oven panel 100, when the distance between the cooker 900 and the first conductive electrode 210 changes, the capacitance parameters of the cooker 900 and the first conductive electrode 210 change, and by arranging the electrical detection structure 300 in the oven body to be electrically connected with the first conductive electrode 210, the electrical signal parameters, such as the current parameters, the voltage parameters and the like, at the first conductive electrode 210 are detected, thereby whether the cooker 900 exists on the oven panel 100 or not can be obtained according to the change of the electrical signal parameters, so as to realize the detection of the cooker 900.
In practical applications, the cooker 900 may be a common cooker made of conductive material, such as a metal cooker, or a cooker made of non-conductive material with conductive food material (such as water or dishes, etc.), such as a ceramic cooker. The electric signal parameters at the first conductive electrode 210 are changed by utilizing the change of the capacitance parameters between the first conductive electrode 210 and the close cookware 900, and the electric signal parameters at the first conductive electrode 210 are detected by the electric detection structure 300, so that the detection function of whether the cookware 900 is arranged on the stove panel 100 is realized, and the phenomenon of empty burning of the stove body can be prevented.
It can be appreciated that the first area a is a projection area of the outline border line of the pan 900 on the oven panel 100, and optionally, a projection area of the upper edge of the pan 900 on the oven panel 100, by setting at least part of the first conductive electrode 210 corresponding to the first area a, the detection effect on the pan 900 is ensured, the pan 900 is prevented from being too far from the first conductive electrode 210, and the electrical signal parameter variation of the first conductive electrode 210 is prevented from being influenced, so that the phenomenon that the detection is not performed is avoided.

At least part of the projection of the first conductive electrode 210 onto the furnace panel 100 is located in the first area a, it is understood that the projection of the first conductive electrode 210 onto the furnace panel 100 may be located in the first area a entirely or partially, and the projection may be located in the first area a without limitation.
Alternatively, the first conductive electrode 210 may be a metal thin film, a metal sheet, a metal block, or a conductive plating, coating, or the like, as long as it is conductive. Alternatively, the first conductive electrode 210 may be one or more.
In practical applications, the electrical detection structure 300 may be a detection circuit or a detection device, and may be capable of inputting an electrical signal to the first conductive electrode 210 and obtaining an electrical signal fed back from the first conductive electrode 210, so as to detect whether the cooker 900 is close to or far from the first conductive electrode 210, and further detect whether the cooker 900 is on the stove panel 100.
In the furnace body of the technical scheme of the utility model, the first conductive electrode 210 is arranged on the furnace panel 100, at least part of the projection of the first conductive electrode 210 on the furnace panel 100 is positioned in the projection area (the first area A) of the cooker 900 on the furnace panel 100, when the cooker 900 is close to or far from the furnace panel 100, the distance between the cooker 900 and the first conductive electrode 210 is also changed, so that the capacitance parameters of the cooker 900 and the first conductive electrode 210 are changed, and the electric detection structure 300 is arranged in the furnace body and is electrically connected with the first conductive electrode 210 for detecting the electric signal parameters fed back by the first conductive electrode 210, so that whether the cooker 900 is arranged on the furnace panel 100 or not can be obtained according to different electric signal parameters, thereby realizing the detection function of the cooker 900. In this embodiment, the change of the capacitance parameter between the first conductive electrode 210 and the close conductive object is used to realize the detection of whether the cooker 900 is on the oven panel 100, without the need of matching the cooker 900 with the oven body, so as to improve the universality of the cooker detection.
In an embodiment of the present utility model, referring to fig. 1 to 4, the projection of the first conductive electrode 210 on the furnace panel 100 is entirely within the first area a.
It can be appreciated that, in this embodiment, the projection of the first conductive electrode 210 on the oven panel 100 is all located in the first area a, and on the basis of the same first conductive electrode 210, compared with the case that only part of the projection is located in the first area a, the area of the pan 900 opposite to the first conductive electrode 210 is increased, and meanwhile, the distance between the pan 900 and the first conductive electrode 210 is also shortened, so that the capacitance between the pan 900 and the first conductive electrode 210 is increased, and the detection effect is further improved.
In an embodiment of the present utility model, referring to fig. 1 to 4, the first conductive electrode 210 is correspondingly located in the middle of the first area a.
In this embodiment, the first conductive electrode 210 is located at the middle position of the first area a, and the first conductive electrode 210 has a smaller distance from the pan 900 no matter whether the pan 900 is placed right or not, so as to further ensure the detection effect of the pan 900.
Alternatively, in practical application, the cooker 900 is usually placed in the middle of the heating area of the oven panel 100, and then the first conductive electrode 210 may be disposed in the middle of the heating area of the oven panel 100, so as to ensure the detection effect.
In an embodiment of the present utility model, referring to fig. 1 to 4, the first conductive electrode 210 has a plurality of surfaces, and the surface with the largest area among the plurality of surfaces is defined as a first surface, and the first surface is parallel to the surface of the furnace panel 100.
It can be appreciated that when the pan 900 is placed on the oven panel 100, the bottom surface of the pan 900 is closer to the oven panel 100, and by setting the surface with the largest area of the first conductive electrode 210 to be parallel to the surface of the oven panel 100, the surface with the largest area of the first conductive electrode 210 is opposite to the bottom surface of the pan 900, so that the opposite areas are increased, the capacitance of the two is larger, and the detection sensitivity is higher.
Alternatively, the first conductive electrode 210 may be a plate-like structure, a bar-like structure, a disk-like structure, or other shaped structure, etc.
In an embodiment of the present utility model, referring to fig. 1 to 4, the electrical detection structure 300 includes an electrical signal generating module for inputting a voltage having an ac component to the first conductive electrode 210, and an electrical signal detecting module for detecting an electrical signal parameter at the first conductive electrode 210.
In this embodiment, the electrical detection structure 300 is configured as a circuit having an electrical signal generating function and an electrical signal detecting function, and the electrical detection structure 300 may be a detection device independently installed in the furnace body, or may be a circuit structure integrated on a main control board or a driving board in the furnace body, such as a chip structure. Alternatively, the electric signal generating module and the electric signal detecting module may be two independent circuits or may be integrated in the same circuit structure.
It can be appreciated that when the cooker 900 is placed on the oven panel 100, a capacitor is formed between the cooker 900 and the first conductive electrode 210, and the capacitor has the characteristics of ac resistance and dc resistance, and high frequency resistance and low frequency, and then an ac voltage or a dc voltage containing an ac component is input to the first conductive electrode 210 through the electric signal generating module, and then the ac voltage is fed back to the electric signal parameter corresponding to the electric signal detecting module through the first conductive electrode 210, so that whether the cooker 900 is located at the first conductive electrode 210 can be successfully detected.
As shown in fig. 4, when the cooker 900 is not on the oven panel 100 (fig. 4 (a)), the capacitance at the first conductive electrode 210 is C1, when the cooker 900 is close to the oven panel 100 but not placed on the oven panel 100 (fig. 4 (b)), the capacitance at the first conductive electrode 210 is C2, when the cooker 900 is placed on the oven panel 100 (fig. 4 (C)), the capacitance at the first conductive electrode 210 is C3, then C1< C2< C3, and further, by detecting the electrical signal parameters such as the voltage signal/current signal at the different first conductive electrodes 210 through the electrical detection structure 300, it can be determined whether the cooker 900 is on the oven panel 100.
Alternatively, the frequency of the ac component in the voltage applied to the first conductive electrode 210 is not lower than 1kHz, and it is understood that the capacitance of the capacitor is inversely related to the frequency, so that the frequency of the ac component cannot be too low, and if the capacitance of the capacitor is too high, the detection sensitivity will be low and the detection effect will be poor. Therefore, the frequency of the input ac component may be increased to reduce the capacitive reactance and improve the detection sensitivity, and optionally, the frequency of the ac component in the voltage applied to the first conductive electrode 210 is not lower than 100kHz, so that the sensitivity is improved and the pot 900 with smaller volume can be detected.
In an embodiment of the present utility model, referring to fig. 1 to 4 and 8, the first conductive electrode 210 is integrated with the electrical detection structure 300.
It will be appreciated that the first conductive electrode 210 may be a separate electrode structure or may be part of the electrical conductor in the electrical detection structure 300.
Alternatively, when the first conductive electrode 210 is a separate electrode structure, the electrical connection with the electrical detection structure 300 may be achieved by connecting the first conductive electrode 210 by wire or by circuit connection or soldering connection. In this way, the first conductive electrode 210 is independent from the outside of the electrical detecting structure 300, and the location of the first conductive electrode 210 is more selective, and the installation location may be determined according to the layout of each structure in the furnace body, for example, may be separately installed on the furnace panel 100, on the heating assembly, or on the housing of the furnace body, etc., which may not be limited herein.
Alternatively, when the first conductive electrode 210 is a conductive body in the electrical detection structure 300, it is understood that a certain wire in the electrical detection structure 300 may be used as the first conductive electrode 210, for example, a connection wire between the electrical signal generating module and the electrical signal detecting module may be used as the first conductive electrode 210, and when the frequency of the electrical signal generating module passing into the connection wire is higher, the connection wire and the close pot 900 may change in electrical signal, so that an electrical signal parameter is detected by the electrical signal detecting module. In this manner, no special first conductive electrode 210 is required.
In one embodiment of the present utility model, the first conductive electrode 210 is disposed on the inner surface of the furnace panel 100; alternatively, the first conductive electrode 210 may be disposed to penetrate both upper and lower surfaces of the furnace panel 100.
It can be appreciated that the location of the first conductive electrode 210 may be determined according to practical situations, for example, may be disposed on the outer surface of the furnace panel 100, may be disposed on the inner surface of the furnace panel 100, or may be disposed on both the upper and lower surfaces of the furnace panel 100.
