Specifically, when porridge or soup is cooked, if no overflow exists, the resistance between the first electrode 201 and the second electrode 202 is very large; if the liquid bubbles overflow, the liquid bubbles generated by boiling food touch the first electrode 201 and the second electrode 202, and the resistance between the first electrode 201 and the second electrode 202 changes under the action of the overflow liquid bubbles, so that the resistance is small.

One end of the columnar electrode (the second electrode 202) is fixed in the pot cover handle 200 and is electrically connected with the MCU203 through a wire inside the pot cover handle 200; the other end of the columnar electrode may extend into the interior of the pot 2, and may be provided with threads on the outer surface, which are screwed with the metal screw cap 206, so that the pot cover handle 200 may be fixed to the pot cover 20 through the columnar electrode and the metal screw cap 206. Namely, the columnar electrode serves as an anti-overflow conductive electrode and a fixing piece at the same time, and plays a role in fixing the pot cover handle 200; in addition, the contact area between the columnar electrode and the overflowing liquid bubble is enlarged by the metal nut 206, so that the leakage judgment is difficult, and the accuracy of the overflowing prevention detection is improved. Of course, the columnar electrode may not extend into the cooker 2, and may be used as an anti-overflow conductive electrode, and the cooker cover handle 200 may be fixed to the cooker cover 20 by other means, and may be specifically set as required.
In addition, the second electrode 202, which is a columnar electrode, may specifically be a temperature sensor 207 with a metal casing, where the temperature sensor 207 extends into the accommodating space of the pan 2, so as to directly test the temperature of air and steam in the pan, and realize accurate temperature measurement. The MCU203 can send a temperature signal to the induction cooker 1 through the sending device 204 according to the temperature value detected by the temperature sensor 207; after the receiving device 10 in the induction cooker 1 receives the temperature signal, the controller 11 in the induction cooker 1 can control the induction cooker 1 to adjust the heating temperature according to the temperature signal, so as to realize accurate temperature control.
The MCU203 and the controller 11 may transmit signals in a wired manner, and the transmitting device 204 and the receiving device 10 are connected through a data transmission line, so as to save cost; the signal can be transmitted in a wireless mode, namely the sending device (204) is a wireless transmitting device, and the receiving device (10) is a wireless receiving device, so that the structural complexity of the cooker is reduced, and the use is convenient for users.

In this embodiment, the interior of the pot cover 20 may be made of an insulating material, such as a glass material, and the outer edge of the pot cover 20 may be provided with a metal ring 208, and the first electrode 201 is electrically connected to the metal ring 208. Specifically, taking the first electrode 201 as an example of a sheet electrode as shown in fig. 2, the metal screw 205 may be located on the metal ring 208 or may be located on the glass of the pot cover 20, and is connected to the metal ring 208 through a section of metal strip on the upper surface or the lower surface of the pot cover 20. Through being connected first electrode 201 and metal ring 208 electricity, can greatly increased the area of contact of first electrode 201 with the vacuole that overflows through metal ring 208, reduce and leak and judge, effectively improve anti-overflow detection accuracy.
Optionally, a metal wafer 209 may be disposed in the middle of the pot cover 20, and the second electrode 202 is electrically connected to the metal wafer 209. Continuing with the example of the second electrode 202 shown in fig. 2 as a cylindrical electrode, the second electrode 202 may be located on a metal disc 209, or may be located on the glass of the lid 20, and connected to the metal disc 209 through a section of metal strip on the upper or lower surface of the lid 20, similar to the first electrode 201. Similarly, through electrically connecting the second electrode 202 with the metal wafer 209, the contact area between the second electrode 202 and overflowing liquid bubbles can be greatly increased through the metal wafer 209, so that the leakage judgment is reduced, and the accuracy of the overflow prevention detection is further improved. It should be noted that, for the convenience of detection, when food does not overflow, the first electrode 201 is insulated from the second electrode 202, i.e. there is a certain space between the metal ring 208 and the metal disc 209.
Furthermore, an electromagnetic field detection device 210 may be further disposed in the pot cover handle 200, and the electromagnetic field detection device 210 is electrically connected with the MCU203 and the first electrode 201 respectively; the electromagnetic field detecting device 210 is configured to detect whether an electromagnetic field exists at the first electrode 201, and the MCU203 is configured to activate the transmitting device 204 when the electromagnetic field detecting device 210 detects the electromagnetic field, and deactivate the transmitting device 204 when the electromagnetic field detecting device 210 does not detect the electromagnetic field.
Specifically, the first electrode 201 may be used as a magnetic field detection point at this time, and as described above, the first electrode 201 is connected to the metal ring 208 on the pot cover 20, where the metal ring 208 may connect, on one hand, the potential difference generated by the alternating electromagnetic field on the pot 2 to the pot cover 20, and on the other hand may serve as an electric wire to collect the electromagnetic field signal to the magnetic field detection point. When the induction cooker 1 heats the cooker 2, the electromagnetic field detection device 210 can detect that the first electrode 201 has an electromagnetic field, and at this time, the MCU203 starts the transmitting device 204; when the pot 2 is not heated or the pot cover 20 is not used, the electromagnetic field detection device 210 can not detect the electromagnetic field at the first electrode 201, and at this time, the MCU203 turns off the transmitting device 204 to save power.
In addition, an indicator lamp 211 may be further disposed on the pot cover handle 200, and the indicator lamp 211 is electrically connected with the MCU 203. When the transmitting device 204 is started, the MCU203 can control the indicator lamp 211 to flash or be normally on; when the transmitting device 204 is started, the MCU203 can control the indicator lamp 211 to be turned off.
The operation principle of the present invention will be described in detail below by taking the mode of detecting overflow prevention by the MCU203 as an example of a voltage detection mode.
FIG. 4 is a schematic diagram of circuitry within the pan lid handle 200, as shown in FIG. 4, a first Input/Output (I/O) port (denoted by I/O1 in FIG. 4) and a digital-to-Analog (AD) port (denoted by AD in FIG. 4) of the MCU203 are electrically connected to the second electrode 202, respectively, and a second I/O port (denoted by I/O2 in FIG. 4) of the MCU203 is electrically connected to the first electrode 201; the electromagnetic field detection device 210 is electrically connected to the MCU203 and the first electrode 201, respectively.
When the electromagnetic field detection module detects that the first electrode 201 has an electromagnetic field, it indicates that the induction cooker 1 is heating the cooker 2, and at this time, the MCU203 turns on the transmitting device 204, and the transmitting device 204 starts to operate.
The MCU203 begins to detect overflows, outputs a high level signal to the first I/O port, and outputs a low level signal to the second I/O port. When food does not overflow, the resistance between the first electrode 201 and the second electrode 202 is very large, and the circuit is similar to a circuit break, and the AD port of the MCU203 detects a high-level analog signal.
When food overflows, the liquid bubbles generated by boiling the food touch the first electrode 201 and the second electrode 202, the resistance between the first electrode 201 and the second electrode 202 changes under the action of the overflowed liquid bubbles, the resistance is very small at this time, the circuit is conducted, and the AD port of the MCU203 detects a low-level analog signal. At this time, the MCU203 transmits an overflow signal to the induction cooker 1 through the transmitting device 204, and after receiving the overflow signal, the receiving device 10 in the induction cooker 1 controls the induction cooker 1 to adjust the heating temperature and the like through the controller 11, so as to prevent the overflow.
When the electromagnetic field detection module detects that the electromagnetic field is weak or not, the cooker 2 is not heated or the cooker cover 20 is not used, and at the moment, the MCU203 turns off the transmitting device 204 to save power.
It should be noted that, in order to ensure the accuracy of detection, when the electromagnetic field detection module detects an electromagnetic field, the MCU203 may set the first I/O port and the second I/O port to a high-impedance state or an input port, so as to prevent signals on the MCU203 from interfering with electromagnetic field signals at the first electrode 201; when detecting an overflow prevention, the first I/O port is set to a high level output and the second I/O port is set to a low level output.
In order to improve the safety of the circuit, a resistor (R in fig. 4) may be connected between the first I/O port and the first electrode 201, and voltage may be divided so that the resistance of the circuit between the first electrode 201 and the second electrode 202 is reduced, and the current is not excessively increased when the circuit is turned on.
In addition, in order to further improve the accuracy of the anti-overflow detection, a capacitor (C in fig. 4) may be connected between the AD port and the second I/O port, and the circuit may be filtered.
According to the overflow-preventing cooking device provided by the invention, the first electrode and the second electrode are arranged on the pot cover, so that the MCU can timely detect the overflow phenomenon according to the resistance change generated by the first electrode and the second electrode when overflow liquid bubbles touch, and an overflow signal is sent to the electromagnetic oven through the sending device; after the receiving device in the induction cooker receives the overflow signal, the controller in the induction cooker can control the induction cooker to adjust the heating temperature and the like according to the overflow signal, so that the overflow event is prevented. Namely, the cooker provided by the invention can realize an automatic overflow prevention detection function, and the first electrode, the second electrode and the MCU are arranged on the cooker cover, so that the connection structure is simple; in addition, the continuous overflowing liquid bubbles do not need to be formed among the first electrode, the second electrode and the pot body, and the overflowing liquid bubbles can realize the anti-overflowing detection only by touching the first electrode and the second electrode, so that the detection omission is not easy to occur, and the detection precision is high.
