[0002] Heating platforms, such as induction cookers, ceramic cooktops, or heating films, are common household appliances. They offer advantages such as safety, lack of open flames, and high energy efficiency. Consequently, more and more users are using these heating platforms to heat pots and pans, such as casseroles, woks, and pressure cookers, for cooking.

[0003] In order to ensure the cooking effect, through the electrical connection (coupling) between the heating platform and the pot, various function detection circuits in the pot can output signals to the heating platform in a timely manner (such as the temperature of the pot, whether the pot is overflowing, or the pressure of the pot, etc.), so that the heating platform can adjust the state of the pot to adapt to the current situation and achieve the boiler linkage effect.

[0070] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0071] Figure 1 This is a schematic diagram of the structure of a heating platform provided in this application. The signal processing method provided in this application is applied to Figure 1 Heating platform shown. Figure 1 In the present application, the heating platform 10 may include: a heating platform body 11, a first contact group 12 and a control circuit 13 ( Figure 1 (not shown in the figure). The heating platform 10 of the present application may include multiple types. Optionally, the heating platform 10 of the present application may include: an induction cooker, an electric ceramic cooker or an electric heating film cooking appliance. For the sake of convenience, Figure 1 In the figure, the heating platform 10 of the present application is illustrated by taking an induction cooker as an example, and the number of the first contact groups 12 is two. The two first contact groups 12 are symmetrically arranged on the upper surface of the heating platform body 11, and the number of the first contacts 121 in each first contact group 12 is illustrated as three.

[0072] In the present application, the number of the first contact group 12 is one or more, and the first contact group 12 is arranged on the heating platform body 11, which is convenient for users to perform operations and simplifies the design, and provides conductive contacts for the cookware 20 to achieve coupling with the heating platform 10 and the cookware 20.

[0073] The present application does not specify the specific location of the first contact group 12 on the heating platform body 11. Alternatively, the first contact group 12 can be positioned above the heating platform body 11, to the side of the heating platform body 11, embedded within the heating platform body 11, or in a combination of the aforementioned arrangements. This application does not specify any of these arrangements. Furthermore, this application does not specify the distribution, shape, or material of the first contact group 12.

[0074] In the present application, the control circuit 13 is electrically connected to the first contacts 121 in each first contact group 12, so that the control circuit 13 can receive signals through the first contacts 121. The control circuit 13 can be an integrated chip, such as a microcontroller unit (MCU), or a circuit composed of an integrated chip and components, such as an MCU and components, which is not limited in the present application.

[0075] In this application, the cookware 20 can be of different types. For example, the cookware 20 can have different functions, shapes, or sizes. The cookware 20 has one or more second contact groups 22. Any second contact group 22 can be matched with any first contact group 12, so that the second contact 221 in the second contact group 22 is in electrical contact with the first contact 121 in the first contact group 12, allowing the control circuit 13 to receive signals.

[0076] Next, combine Figure 1 The heating platform 10 shown in FIG. Figure 1 The control circuit 13 is the execution body, and the specific implementation process of the signal processing method provided by this application is described in detail through specific embodiments.

[0077] Figure 2 This is a flow chart of a signal processing method provided by this application. Figure 2 As shown, the signal processing method provided by this application may include:

[0078] S101. When the heating platform is matched with the cookware, the control circuit obtains a plurality of signals based on electrical contact between at least one first contact group and a corresponding second contact group in the cookware, the plurality of signals including at least one functional signal.

[0079] In the present application, the user places the cookware 20 on the heating platform 10, the heating platform 10 can be matched with the cookware 20, and one or more first contact groups 12 in the heating platform 10 can be electrically contacted with the corresponding second contact groups 22 in the cookware 20, that is, a first contact group 12 in the heating platform 10 can be connected to a corresponding second contact group 22 in the cookware 20, or, multiple first contact groups 12 in the heating platform 10 can be connected to one or more corresponding second contact groups 22 in the cookware 20, so as to realize coupling between the first contact group 12 and the second contact group 22, so that the control circuit 13 receives multiple signals from one or more first contact groups 12, so that the control circuit 13 performs corresponding processing based on the multiple signals received.

[0080] For example, when the control circuit 13 receives a temperature signal, the control circuit 13 can control the heating platform to display the current temperature to the user, or the control circuit 13 controls the heating platform 10 to stop heating the pot 20 due to detecting that the temperature is too high, or controls the heating platform 10 to continue heating the pot 20 due to detecting that the temperature is too low, etc.

[0081] The multiple signals may be two or more in number, and the types of the multiple signals may include functional signals and prompt signals. In other words, the multiple signals may include one or more functional signals and one or more other signals. The functional signal indicates the properties of the cookware 20 and is typically detected by sensors or other detection components. This application does not limit the specific representation of the functional signal. Optionally, the functional signal may include at least one of an overflow signal, a temperature signal, a water level signal, and a pressure signal. The overflow signal indicates whether the food in the cookware 20 is overflowing. The temperature signal may be the temperature of the inner surface of the cookware 20, the temperature of the outer surface of the cookware 20, the average temperature of the cookware 20, the temperature of the bottom of the cookware 20, or the temperature of the sidewalls of the cookware 20, all of which are not limited in this application. The pressure signal indicates the pressure in the cookware 20. The water level signal indicates the height of the food in the cookware 20. The prompt signal, such as a coupling signal, indicates that the cookware 20 is successfully coupled to the heating platform 10. The prompt signal may be a digital signal or an analog signal, and the present application does not limit the specific implementation form of the prompt signal.

[0082] It should be noted that the types of the multiple signals acquired by the control circuit 13 may include only functional signals, or may include functional signals and prompt signals, and this application does not limit this.

[0083] S102: The control circuit determines the type of the functional signal received from the cookware based on the characteristics of the signal.

[0084] In the present application, the control circuit 13 can also determine the characteristics of the signals while acquiring multiple signals. The characteristics of the signals can be used to indicate the type of functional signal among the multiple signals. Therefore, the control circuit 13 can determine the type of functional signal received from the cookware 20 based on the characteristics of the signals, so that the control circuit 13 can know the type of each signal, which is conducive to the control circuit 13 accurately performing corresponding operations and avoiding the occurrence of erroneous operations.

[0085] The signal processing method provided in this application can obtain multiple signals by the control circuit in the heating platform when the heating platform and the cookware are matched, based on the electrical contact between one or more first contact groups in the heating platform and the corresponding second contact groups in the cookware, wherein the multiple signals include at least one functional signal. Since the characteristics of the signal can be used to indicate the type of functional signal among the multiple signals, the control circuit can determine the type of functional signal received from the cookware based on the characteristics of the signal. Thus, by accurately knowing the type of each signal, the heating platform can accurately obtain the properties of the cookware, which is beneficial for the heating platform to fully understand the current status of the cookware so that it can promptly perform operations corresponding to the type of signal, thereby achieving a linkage effect between the heating platform and the cookware.

[0086] In the above Figure 1-Figure 2 Based on the illustrated embodiments, in this application, the characteristics of a signal may represent the type of one or more signals, the number of signals, the position of one or more signals, the serial number of one or more signals, or any combination of the aforementioned methods, and this application does not limit this.

[0087] In the following, two feasible implementations are combined to illustrate the specific implementation process of the control circuit 103 in S102 determining the type of the functional signal received from the cookware 20 based on the characteristics of the signal.

[0088] In one feasible implementation, the control circuit 13 may pre-store a correspondence between the number of signals and the type of signals. This correspondence may be stored in a variety of ways, such as a table, a series, and a matrix, which is not limited in this application. Furthermore, this correspondence may be set based on the number of signals actually transmitted by any one of the cookware 20, or based on the number of signals transmitted by different types of cookware 20 compatible with the heating platform 10, or based on a combination of the first two methods, which is not limited in this application.

[0089] Thus, the control circuit 13 can determine the number of signals received from the cookware 20 based on the characteristics of the signals, so that the control circuit 13 can determine the type of functional signal received from the cookware 20 based on the correspondence between the number of signals and the type of signals.

[0090] For example, assuming that the number of signals is 1, the signal type includes a temperature signal; and the number of signals is 2, the signal type includes a temperature signal and a pressure signal. Thus, when the number of signals received by the control circuit 13 is 2, the control circuit 13 can determine that the type of the functional signal received from the cookware 20 includes a temperature signal and a pressure signal, so that the control circuit 13 performs operations corresponding to the temperature signal and the pressure signal, respectively.

[0091] The number of signals may be the total number of multiple signals, or the total number of signals received from the first contact group 12 located on one side of the heating platform body 11 , which is not limited in this application.

[0092] In addition, when the heating platform 10 can be compatible with multiple types of pots 20, the control circuit 13 can also pre-store the correspondence between the number of signals and the type of pot. This correspondence can be stored in a variety of ways, such as a table, a series, and a matrix, and this application does not limit this. Thus, based on the characteristics of the signals, the control circuit 13 can determine the number of signals received from the pot 20. This allows the control circuit 13 to determine the type of pot 20 based on the correspondence between the number of signals and the type of pot. This not only distinguishes the type of pot 20 that can be compatible with the heating platform 10, achieving precise control of the heating platform 10, but also distinguishes the coupling state of any pot 20 placed on the heating platform 10 in a variety of matching positions, such as when placed upright or inverted. The matching position is used to indicate the coupling state of the pot 20 and the heating platform 10 for signal transmission.

[0093] For example, combined with Figure 3 For ease of explanation, Figure 3 In the figure, the number of the first contact groups 12 in the heating platform 10 is indicated as two, and the number of the first contacts 121 in each first contact group 12 is indicated as three. Figure 3 There are two types of pots 20, namely a stew pot A and a soup pot B. An example is given in which a second contact group 22 is provided on one side of each pot 20, and the second contact group 22 includes three second contacts 221.

[0094] Assume that the correspondence between the number of signals and the type of pot is: if the number of signals is 1, the type of pot 20 is stew pot A; if the number of signals is 2, the type of pot 20 is soup pot B. Figure 3 As shown, when the pot 20 is placed on the heating platform 10, if the number of signals received by the control circuit 13 is 1, the control circuit 13 can determine that the type of pot placed on the heating platform 10 is a stew pot A, so that the control circuit 13 can perform corresponding operations. If the number of signals received by the control circuit 13 is 2, the control circuit 13 can determine that the type of pot placed on the heating platform 10 is a soup pot B, so that the control circuit 13 can perform corresponding operations.

[0095] Based on the above description, when the heating platform 10 includes a first contact group 12, the control circuit 13 can accurately determine the type of functional signal transmitted by the second contact group 22 that matches the first contact group 12. By changing the matching position (i.e., the coupling state of the cookware 20), the control circuit 13 can accurately determine the type of functional signal transmitted by multiple second contact groups 22 in the cookware 20. This facilitates selecting different second contact groups 22 in the cookware 20 to match with the first contact group 12 on the heating platform 10 according to actual needs, allowing the control circuit 13 to obtain the desired functional signal, thereby allowing the control circuit 13 to promptly understand the properties and characteristics of the cookware 20 and making corresponding adjustments.

[0096] When the heating platform 10 includes two or more first contact groups 12, the control circuit 13 can determine the number of signals received from each of the multiple first contact groups 12 based on the signal characteristics, allowing the control circuit 13 to determine the type of functional signal transmitted by the second contact group 22 matching each first contact group 12, so that the control circuit 13 can accurately determine the type of functional signal transmitted by the multiple second contact groups 22 in the cookware 20. This makes it convenient to select different second contact groups 22 in the cookware 20 to match with the multiple first contact groups 12 on the heating platform 10 according to actual needs, allowing the control circuit 13 to obtain the desired functional signal, thereby allowing the control circuit 13 to promptly understand the properties and characteristics of the cookware 20 and making corresponding adjustments.

[0097] Optionally, when multiple first contact groups 12 are located on both sides of the heating platform body 11, the control circuit 13 may determine a first number of signals received from the first contact group 12 located on one side of the heating platform body 11, and a second number of signals received from the first contact group 12 located on the other side of the heating platform body 11. Because the control circuit 13 pre-stores a correspondence between numbers and signal types, when the first number and the second number are different, the control circuit 13 may compare the correspondence between the numbers and signal types to determine the type of each functional signal obtained from the corresponding first contact group on either side of the heating platform body 11, thereby determining the type of the functional signal received from the cookware.

[0098] It should be noted that, based on the above, the control circuit 13 may also pre-store a correspondence between quantities and the order of arrangement of signals. This correspondence may be stored in a variety of ways, such as a table, a series, or a matrix, and this application does not limit this. Thus, by comparing the correspondence between quantities and the order of arrangement of signals, the control circuit 13 can determine the positional relationship of each functional signal.

[0099] For example, assuming a correspondence between the number of signals and the order in which they are received: if the number of signals is 2, the order in which the signals are received from either side of the heating platform body 11 is temperature signal and pressure signal; if the number of signals is 2, the order in which the signals are received from that side of the heating platform body 11 is temperature signal, pressure signal, and water level signal. Thus, when the control circuit 13 receives 2 signals, it can determine that the order in which the signals are received is temperature signal and pressure signal, so that the control circuit 13 can perform the corresponding operation.

[0100] In addition, the control circuit 13 may also pre-store a correspondence between the quantity and the coupling state of the pot. This correspondence may be stored in a variety of ways, such as a table, a number series, and a matrix, and this application does not limit this. Thus, when the first quantity and the second quantity are different, the control circuit 13 can determine whether the heating platform 10 and the pot 20 are successfully coupled to the front or back by comparing the correspondence between the quantity and the coupling state of the pot. The control circuit 13 can also prompt the user that the heating platform 10 and the pot 20 are successfully coupled to the front or back, such as by displaying corresponding text on the display screen on the heating platform body 11 or by using different colored lights on the heating platform body 11 to provide the user with the corresponding prompt. Alternatively, the aforementioned two processes can be performed, and this application does not limit this.

[0101] In this way, when the user places the cookware 20 on the heating platform 10, there is no need to consider the front or back of the cookware 20, and the front or back of the cookware 20 can be successfully coupled to the heating platform 10, which is conducive to simplifying and facilitating user operation and improving the user's experience.

[0102] For example, combined with Figure 4 For ease of explanation, Figure 4 In the figure, the number of the first contact groups 12 in the heating platform 10 is indicated as two, the number of the first contacts 121 in each first contact group 12 is indicated as three, and Figure 4 The middle pot 20 is illustrated by taking an example in which a second contact group 22 is respectively provided on both sides of the pot 20, wherein one second contact group 22 includes three second contacts 221 for transmitting one functional signal, and the other second contact group 22 includes four second contacts 221 for transmitting two functional signals.

[0103] Assume that the corresponding relationship between the number of signals and the coupling state of the pot is: if the number of signals is 1, the coupling state of the pot is positive; if the number of signals is 2, the coupling state of the pot is negative. Figure 4As shown, when the number of function signals received by the control circuit 13 is 1, the control circuit 13 can determine that the cookware 20 is placed on the heating platform 10, that is, the heating platform 10 and the front side of the cookware 20 are successfully coupled, so that the control circuit 13 can perform the corresponding operation. When the number of function signals received by the control circuit 13 is 2, the control circuit 13 can determine that the cookware 20 is placed on the heating platform 10 upside down, that is, the heating platform 10 and the back side of the cookware 20 are successfully coupled, so that the control circuit 13 can perform the corresponding operation.

[0104] In another feasible implementation, the control circuit 13 can determine the types of the multiple signals based on the multiple signals received. When the control circuit 13 determines that the multiple signals include one or more prompt signals and one or more function signals, since the prompt signal can be used to indicate successful coupling between the heating platform 10 and the cookware 20, the control circuit 13 can determine characteristics of the prompt signal, such as the quantity, position, or sequence number, so that the control circuit 13 can determine the type of the function signal among the multiple signals, that is, determine the type of the function signal received from the cookware 20.

[0105] For example, assuming the number of prompt signals is 1 and the type of function signal includes a temperature signal; and the number of prompt signals is 2 and the type of function signal includes a temperature signal and a pressure signal. Thus, when the number of prompt signals received by the control circuit 13 is 2, the control circuit 13 can determine that the type of function signal received from the cookware 20 includes a temperature signal and a pressure signal, so that the control circuit 13 performs operations corresponding to the temperature signal and the pressure signal, respectively.

[0106] For another example, assume that the prompt signal is located on side A of the heating platform body 11 and the type of function signal includes a temperature signal; and that the prompt signal is located on side B of the heating platform body 11 and the type of function signal includes a temperature signal and a pressure signal. Thus, when the prompt signal received by the control circuit 13 is located on side A of the heating platform body 11, the control circuit 13 can determine that the type of function signal received from the cookware 20 includes a temperature signal, and the control circuit 13 can perform an operation corresponding to the temperature signal.

[0107] Optionally, the control circuit 13 may determine the position of the first contact 121 in the first contact group 12 corresponding to the prompt signal, so that the control circuit 13 determines the type of functional signals corresponding to the first contacts 121 at other positions based on the position.

[0108] The control circuit 13 stores in advance the type of functional signal corresponding to any position. This storage may be in the form of a table or list, and is not limited in this application. In addition, for ease of storage, the control circuit 13 may store in advance the correspondence between the sequence number and the position, so that the control circuit 13 can determine the position corresponding to the prompt signal based on the sequence number of the prompt signal.

[0109] The first contact group 12 is provided with one or more first contacts 121, each of which is used for conducting electricity to achieve signal reception or transmission, and can be made of a conductive material such as metal. The number of first contacts 121 in each first contact group 12 can be the same or different, and this application does not limit this. The first contact group 12 can include only the first contacts 121, or it can include the first contacts 121 and other components that protect or fix the first contacts 121. This application does not limit the specific implementation form of the first contact group 12. In addition, when the first contact group 12 includes multiple first contacts 121, this application does not limit the signal transmission order and spacing between the multiple first contacts 121.

[0110] Furthermore, when the heating platform 10 includes at least two first contact groups 12, the heating platform 10 and any one of the cookware 20 have at least two matching positions, and signals can be transmitted between the heating platform 10 and any one of the cookware 20 at each matching position, the control circuit 13 may also pre-store a correspondence between the position and the coupling state of the cookware. This correspondence may be stored in various ways, such as a table, a series, and a matrix, and this application is not limited thereto.

[0111] Thus, the control circuit 13 can determine whether the heating platform 10 and the cookware 20 are successfully coupled on the front side or the back side by comparing the correspondence between the position and the coupling state of the cookware, and can also prompt the user whether the heating platform 10 and the cookware 20 are successfully coupled on the front side or the back side, such as using a display screen on the heating platform body 11 to display corresponding text to the user or using lights of different colors on the heating platform body 11 to give corresponding prompts to the user, etc. The above two processes can also be performed, and this application does not limit this.

[0112] In this way, the heating platform 10 can also distinguish the coupling state of any pot 20 placed on the heating platform 10 in a variety of matching positions, such as upright or inverted. Moreover, when the user places the pot 20 on the heating platform 10, it does not matter whether the pot 20 is facing forward or backward, as the pot 20 can be successfully coupled to the heating platform 10 from either side, which simplifies and facilitates user operation and improves user experience.

[0113] For example, combined with Figure 5For ease of explanation, Figure 5 In the figure, the number of the first contact groups 12 in the heating platform 10 is indicated as two, the number of the first contacts 121 in each first contact group 12 is indicated as three, and Figure 5 The middle cooker 20 is illustrated by taking an example in which a second contact group 22 is respectively provided on both sides of the cooker 20, and each second contact group 22 includes three second contacts 221, which can be used to transmit one or two functional signals.

[0114] Assume that the corresponding relationship between the position and the coupling state of the pot is: if the prompt signal is located on the A side of the heating platform body 11, the coupling state of the pot is the front side; if the prompt signal is located on the B side of the heating platform body 11, the coupling state of the pot is the back side. Figure 5 As shown, when the control circuit 13 determines that the prompt signal is located on side A of the heating platform body 11, the control circuit 13 can determine that the pot 20 is placed on the heating platform 10, that is, the heating platform 10 and the pot 20 are successfully coupled from the front, so that the control circuit 13 can perform the corresponding operation. When the control circuit 13 determines that the prompt signal is located on side B of the heating platform body 11, the control circuit 13 can determine that the pot 20 is placed on the heating platform 10 upside down, that is, the heating platform 10 and the pot 20 are successfully coupled from the back, so that the control circuit 13 can perform the corresponding operation.

[0115] In the present application, there are multiple methods for the control circuit 13 to obtain the prompt signal. Below, three implementation methods are used to illustrate the specific process of the control circuit 13 obtaining the prompt signal.

[0116] In one embodiment, if any second contact 221 in at least one second contact group 22 located on both sides of the cookware 20, except for the second contact 221 corresponding to the function signal, is short-circuited, and when the heating platform 10 and the cookware 20 are mated, the second contact group 22 can be coupled to the first contact group 12, so that the short-circuited second contact 221 can short-circuit the first contact 121 in the first contact group 12. Thus, the control circuit 13 determines the signal generated by the short-circuited first contact 121 as a prompt signal.

[0117] The second contact group 22 may include one or more second contacts 221, each of which is used for conducting electricity to enable signal reception or transmission, and may be made of a conductive material such as metal. The second contact group 22 may include only the second contacts 221, or may include the second contacts 221 and other components that protect or secure the second contacts 221. This application does not limit the specific implementation of the second contact group 22. Furthermore, when the second contact group 22 includes multiple second contacts 221, this application does not limit the order in which the multiple second contacts 221 transmit signals or the spacing between them.

[0118] In another embodiment, if a second contact 221 specifically for transmitting a prompt signal is pre-set in the second contact group 12, then when the cookware 20 is matched with the heating platform 10, the control circuit 13 can determine that the signal received by the first contact 221 coupled to the second contact 221 is a transmission prompt signal. Thus, the control circuit 13 can determine that the signal received from the first contact 121 coupled to the pre-set second contact 221 is a prompt signal.

[0119] In another embodiment, if the first contact group 12 is pre-set with a first contact 121 specifically for receiving a prompt signal, then when the cookware 20 is paired with the heating platform 10, the second contact 221 coupled to the first contact 121 is configured to transmit a prompt signal. Thus, the control circuit 13 can determine that the signal received from the pre-set first contact 121 is a prompt signal.

[0120] Illustratively, the present application also provides an electronic device. Figure 6 This is a schematic diagram of the hardware structure of the electronic device provided in this application. Figure 6 As shown, the electronic device 100 is used to implement the operation corresponding to the control circuit in the heating platform in any of the above method embodiments. The electronic device 100 of the present application may include: a memory 101 and a processor 102;

[0121] Memory 101, used for storing computer programs;

[0122] The processor 102 is configured to execute the computer program stored in the memory to implement the signal processing method in the above embodiment. For details, please refer to the relevant description in the above method embodiment.

[0123] Optionally, the memory 101 may be independent or integrated with the processor 102 .

[0124] When the memory 101 is a device independent of the processor 102, the electronic device 100 may further include:

[0125] The bus 103 is used to connect the memory 101 and the processor 102 .

[0126] Optionally, the present application may further include: a communication interface 104, which may be connected to the processor 102 via the bus 103. The processor 102 may control the communication interface 103 to implement the above-mentioned receiving and sending functions of the electronic device 100.

[0127] The electronic device provided by this application can be used to perform the above Figure 2-Figure 5 The signal processing method shown has similar implementation methods and technical effects, and will not be described in detail in this application.

[0128] Exemplarily, the present application further provides a computer-readable storage medium, the computer-readable storage medium including a computer program, the computer program being used to implement the above Figure 2-Figure 5 The signal processing method in the illustrated embodiment.

[0129] Exemplarily, the present application also provides a heating platform 10. Figure 1 The heating platform 10 of the present application can perform the above Figure 2-Figure 5 The specific implementation principles and technical effects of the signal processing method in the illustrated embodiment can be found in the above method embodiments, and will not be repeated in this application.

[0130] In this application, the user places the cookware 20 on the heating platform 10, the heating platform 10 can be matched with the cookware 20, and one or more first contact groups 12 in the heating platform 10 can be electrically contacted with the corresponding second contact groups 22 in the cookware 20 to achieve coupling between the first contact groups 12 and the second contact groups 22, so that the control circuit 13 receives multiple signals from one or more first contact groups 12, so that the control circuit 13 performs corresponding processing based on the multiple signals received.

[0131] Furthermore, while acquiring multiple signals, the control circuit 13 can also determine the characteristics of the signals. The characteristics of the signals can be used to indicate the type of functional signal among the multiple signals. Thus, the control circuit 13 can determine the type of functional signal received from the cookware 20 based on the characteristics of the signals. This allows the control circuit 13 to know the type of each signal, which helps the control circuit 13 accurately perform corresponding operations and avoids erroneous operations.

[0132] The heating platform provided in the present application can obtain multiple signals by the control circuit based on the electrical contact between one or more first contact groups and the corresponding second contact groups in the cookware when the heating platform is matched with the cookware, wherein the multiple signals include at least one functional signal. Since the characteristics of the signal can be used to indicate the type of functional signal among the multiple signals, the control circuit can determine the type of functional signal received from the cookware based on the characteristics of the signal. Thus, by accurately knowing the type of each signal, the heating platform can accurately obtain the properties of the cookware, which is beneficial for the heating platform to fully understand the current status of the cookware so that it can promptly perform operations corresponding to the type of signal, thereby achieving a linkage effect between the heating platform and the cookware.

[0133] In the following, two feasible implementations are combined to illustrate the specific implementation process of the control circuit 103 determining the type of the functional signal received from the cookware 20 based on the characteristics of the signal.

[0134] In a feasible implementation, the control circuit 13 is configured to determine the number of signals received from the cookware 20 , and determine the type of the functional signal received from the cookware 20 based on a correspondence between the number of signals and the type of the signals.

[0135] Optionally, when the heating platform 10 includes at least two first contact groups, the control circuit 13 is used to determine the number of signals received from each of the multiple first contact groups 122, so that the control circuit 13 determines the type of functional signal transmitted by the second contact group 22 matching each first contact group 12.

[0136] Optionally, when at least two first contact groups 12 are located on both sides of the heating platform body 11, the control circuit 13 is specifically used to determine a first number of signals received from the first contact group 12 located on one side of the heating platform body 11, and a second number of signals received from the first contact group 12 located on the other side of the heating platform body 11, and when the first number is different from the second number, compare the correspondence between the number and the type of signal to determine the type of functional signal received from the cookware 20.

[0137] Optionally, the control circuit 13 is also used to compare the correspondence between the quantity and the coupling state of the cookware 20 when the first quantity is different from the second quantity, determine whether the heating platform 10 is successfully coupled to the front or back of the cookware 20, and / or prompt the user that the heating platform 10 is successfully coupled to the front or back of the cookware 20.

[0138] In this way, when the user places the cookware 20 on the heating platform 10, there is no need to consider the front or back of the cookware 20, and the front or back of the cookware 20 can be successfully coupled to the heating platform 10, which is conducive to simplifying and facilitating user operation and improving the user's experience.

[0139] In another feasible implementation, when at least one second contact group 22 is provided on the cookware 20, the control circuit 13 is used to determine that the multiple signals include at least two types of signals, wherein at least one type of signal is a prompt signal and the remaining types of signals are functional signals; and based on the characteristics of the prompt signal, determine the type of functional signal received from the cookware 20.

[0140] Optionally, the control circuit 13 is configured to determine the position of the contact in the first contact group 12 corresponding to the prompt signal, and based on the position, determine the type of functional signals corresponding to the contacts at other positions.

[0141] Optionally, the control circuit 13 is further configured to determine whether the heating platform 10 is successfully coupled to the front or back of the pot 20 based on the position, and / or to prompt the user that the heating platform 10 is successfully coupled to the front or back of the pot 20.

[0142] In this way, when the user places the cookware 20 on the heating platform 10, there is no need to consider the front or back of the cookware 20, and the front or back of the cookware 20 can be successfully coupled to the heating platform 10, which is conducive to simplifying and facilitating user operation and improving the user's experience.

[0143] In the present application, there are multiple methods for the control circuit 13 to obtain the prompt signal. Below, three implementation methods are used to illustrate the specific process of the control circuit 13 obtaining the prompt signal.

[0144] In one embodiment, when any second contact 221 other than the second contact 221 corresponding to the functional signal in at least one second contact group 22 located on both sides of the cookware 20 is short-circuited, the control circuit 13 is configured to determine a signal generated based on the short-circuit connection of the first contacts 121 in at least two first contact groups 12 as a prompt signal.

[0145] In a specific embodiment, Figure 7 As shown, it is assumed that two first contact groups 12 are provided on the heating platform 10, which are respectively denoted as CN1 and CN2. The first contacts 121 in the two first contact groups 12 are axially symmetrically arranged.

[0146] The first contact group 12, labeled CN1, includes three first contacts 121, labeled A1, B1, and C1. The first contact group 12, labeled CN2, includes three first contacts 121, labeled A2, B2, and C2. A control circuit 13, labeled M, is electrically connected to each first contact 121.

[0147] Assume that two second contact groups 22 are provided on the cooker 20, which are respectively denoted as CN3 and CN4. The third contacts in the two second contact groups 22 are arranged symmetrically about the axis.

[0148] The second contact group 22, labeled CN3, includes three second contacts 221, labeled A1', B1', and C1'. The second contact group 22, labeled CN4, includes three second contacts 221, labeled A2', B2', and C2'. One function detection circuit 23 is a temperature detection circuit N1, connected between the two second contacts 221 (A1' and B1'). The temperature detection circuit N1 is configured to output a temperature signal. Another function detection circuit 23 is an overflow detection circuit N2, connected between the two second contacts 221 (A2' and B2'). The overflow detection circuit N2 is configured to output an overflow signal. The second contact 221 (C1') in the second contact group 22, labeled CN3, is short-circuited to the second contact 221 (C2') in the second contact group 22, labeled CN4.

[0149] like Figure 7 As shown, when the pot 20 is placed on the heating platform 10, CN1 is in contact with CN3, CN2 is in contact with CN4, and the control circuit 13 detects that C1 in CN1 and C2 in CN2 are short-circuited to obtain a prompt signal.

[0150] Therefore, based on the prompt signal, the control circuit 13 can obtain a temperature signal from the temperature detection circuit N1 by matching A1 in CN1 with A1' in CN3, and B1 in CN1 with B1' in CN3. Furthermore, the control circuit 13 can obtain an overflow signal from the overflow detection circuit N2 by matching A2 in CN2 with A2' in CN4, and B2 in CN2 with B2' in CN4.

[0151] In another embodiment, the control circuit 13 is configured to determine a signal received from the first contact 121 in the first contact group 12 coupled to the second contact 221 preset in the second contact group 22 as a prompt signal.

[0152] In a specific embodiment, Figure 8a As shown, it is assumed that two first contact groups 12 are provided on the heating platform 10, which are respectively denoted as CN1 and CN2. The first contacts 121 in the two first contact groups 12 are symmetrically arranged.

[0153] The first contact group 12, labeled CN1, includes three first contacts 121, labeled A1, B1, and C1. The first contact group 12, labeled CN2, includes three first contacts 121, labeled A2, B2, and C2. A control circuit 13, labeled M, is electrically connected to each first contact 121.

[0154] Assume that two second contact groups 22 are provided on the cooker 20, which are respectively denoted as CN3 and CN4. The second contacts 221 in the two second contact groups 22 are arranged axially symmetrically.

[0155] The second contact group 22, labeled CN3, includes three second contacts 221, labeled A1', B1', and C1'. A1' and C1' are functional contacts, and B1' is a ground contact. The second contact group 22, labeled CN4, includes three second contacts 221, labeled A2', B2', and C2'. A2' and C2' are functional contacts, and B2' is a ground contact.

[0156] One function detection circuit 23 is a temperature detection circuit N1, which is connected between the two second contacts 221 (A1' and B1'). The function signal output by the temperature detection circuit N1 is a temperature signal. The other function detection circuit 23 is a water level detection circuit N3, which is connected between the two second contacts 221 (B1' and C1'). The function signal output by the water level detection circuit N3 is a water level signal.

[0157] One function detection circuit 23 is an overflow detection circuit N2, connected between the two second contacts 221 (A2' and B2'). The function signal output by the overflow detection circuit N2 is an overflow signal. The other function detection circuit 23 is a coupling detection circuit N4, connected between the two second contacts 221 (B2' and C2'). The function signal output by the coupling detection circuit N4 is a prompt signal.

[0158] like Figure 8a As shown, when the pot 20 is placed on the heating platform 10, CN1 is in contact with CN3, CN2 is in contact with CN4, and the control circuit 13 obtains a prompt signal from C2' in CN4 coupled with C2 preset in CN2 and transmitting a prompt signal.

[0159] Thus, based on this prompt signal, the control circuit 13 can obtain a temperature signal from the temperature detection circuit N1 by matching A1 in CN1 with A1' in CN3, and matching B1 in CN1 with B1' in CN3. Furthermore, the control circuit 13 can obtain an overflow signal from the overflow detection circuit N2 by matching A2 in CN2 with A2' in CN4, and matching B2 in CN2 with B2' in CN4. Furthermore, the control circuit 13 can obtain a water level signal from the water level detection circuit N3 by matching C1 in CN1 with C1' in CN3, and matching B1 in CN1 with B1' in CN3.

[0160] In another specific embodiment, Figure 8b As shown, it is assumed that two first contact groups 12 are provided on the heating platform 10, which are respectively denoted as CN1 and CN2. The first contacts 121 in the two first contact groups 12 are centrally symmetrically arranged.

[0161] The first contact group 12, labeled CN1, includes four first contacts 121, labeled A1, B1, C1, and D1. The first contact group 12, labeled CN2, includes four first contacts 121, labeled A2, B2, C2, and D2. A control circuit 13, labeled M, is electrically connected to each first contact 121.

[0162] Assume that two second contact groups 22 are provided on the cooker 20, which are respectively denoted as CN3 and CN4. The second contacts 221 in the two second contact groups 22 are arranged axially symmetrically.

[0163] The second contact group 22, labeled CN3, includes four second contacts 221, designated A1', B1', C1', and D1'. A1' and C1' are functional contacts, and B1' and D1' are ground contacts. The second contact group 22, labeled CN4, includes four second contacts 221, designated A2', B2', C2', and D2'. A2' and C2' are functional contacts, and B2' and D2' are ground contacts.

[0164] One function detection circuit 23 is a temperature detection circuit N1, which is connected between the two second contacts 221 (A1' and B1'). The function signal output by the temperature detection circuit N1 is a temperature signal. The other function detection circuit 23 is a water level detection circuit N3, which is connected between the two second contacts 221 (C1' and D1'). The function signal output by the water level detection circuit N3 is a water level signal.

[0165] One function detection circuit 23 is an overflow detection circuit N2, connected between the two second contacts 221 (A2' and B2'). The function signal output by the overflow detection circuit N2 is an overflow signal. The other function detection circuit 23 is a coupling detection circuit N4, connected between the two second contacts 221 (C2' and D2'). The function signal output by the coupling detection circuit N4 is a prompt signal.

[0166] like Figure 8b As shown, when the pot 20 is placed on the heating platform 10, CN1 is in contact with CN3, CN2 is in contact with CN4, and the control circuit 13 obtains a prompt signal from C2' in CN4 coupled with C2 preset in CN2 and transmitting a prompt signal.

[0167] Thus, based on this prompt signal, the control circuit 13 can obtain a temperature signal from the temperature detection circuit N1 by matching A1 in CN1 with A1' in CN3, and matching B1 in CN1 with B1' in CN3. Furthermore, the control circuit 13 can obtain an overflow signal from the overflow detection circuit N2 by matching A2 in CN2 with A2' in CN4, and matching B2 in CN2 with B2' in CN4. Furthermore, the control circuit 13 can obtain a water level signal from the water level detection circuit N3 by matching C1 in CN1 with C1' in CN3, and matching B1 in CN1 with B1' in CN3.

[0168] In another embodiment, the control circuit 13 is configured to determine a signal received from a first contact 121 preset in the first contact group 12 as a prompt signal.

[0169] Continue to combine Figure 8a or Figure 8b When the pot 20 is placed on the heating platform 10, CN1 is in contact with CN3, CN2 is in contact with CN4, and the control circuit 13 obtains the prompt signal from C2' in CN4 which is preset and receives the prompt signal.

[0170] Thus, based on this prompt signal, the control circuit 13 can obtain a temperature signal from the temperature detection circuit N1 by matching A1 in CN1 with A1' in CN3, and matching B1 in CN1 with B1' in CN3. Furthermore, the control circuit 13 can obtain an overflow signal from the overflow detection circuit N2 by matching A2 in CN2 with A2' in CN4, and matching B2 in CN2 with B2' in CN4. Furthermore, the control circuit 13 can obtain a water level signal from the water level detection circuit N3 by matching C1 in CN1 with C1' in CN3, and matching B1 in CN1 with B1' in CN3.

[0171] Optionally, there is at least one multiplexing contact 121A in the first contact 121. For any multiplexing contact 121A, the multiplexing contact 121A can receive different types of signals to achieve signal multiplexing. Among them, the present application does not limit the number and type of signals that the multiplexing contact 121A can receive. Optionally, all the first contacts 121 are multiplexing contacts 121A, so that the number of signals that the first contact 121 can receive is maximized. Optionally, some of the first contacts 121 are multiplexing contacts 121A, which facilitates the design of the first contact 121. In addition, the first contacts 121 arranged on both sides of the heating platform body 11 can be arranged symmetrically so that the first contact 121 can transmit multiple types of signals when used as a multiplexing contact 221A.

[0172] For example, when the first contact 121 is a multiplexing contact 121A, the multiplexing contact 121A can receive signal 1 and signal 2. Alternatively, the multiplexing contact 121A can receive signal 1, signal 2, and signal 3. Signal 1, signal 2, and signal 3 are different types of signals. Furthermore, for any two multiplexing contacts 121A, the signals that can be received by the two multiplexing contacts 121A can be of the same type or different types, and this application does not limit this.

[0173] Since the multiplexed contact 121A in the first contact group 12 can receive different types of signals, based on the first contact 121 in the first contact group 12, matching with the second contact group 22 in the cookware 20 can be achieved, so that the heating platform 10 can receive various types of signals sent by the cookware 20 through the first contact group 12, so that the heating platform 10 and the cookware 20 are successfully coupled, thereby reducing the number of conductive contacts.

[0174] The present application does not limit the number of first contacts 121 in the first contact group 12. Optionally, the number of first contacts 121 in each first contact group 12 may be the same or different.

[0175] Exemplarily, the present application also provides a stove assembly. Figure 9 This is a schematic diagram of the structure of the stove assembly provided in this application. Figure 9 As shown, the stove assembly 1 of the present application may include: a heating platform 10 and a pot 20.

[0176] Among them, the heating platform 10 can be seen Figure 1-Figure 8a 、 Figure 8b The description of the embodiment shown is not repeated here. The heating platform 10 of the present application may include multiple types. Optionally, the heating platform 10 of the present application may include: an induction cooker, an electric ceramic cooker or an electric film heating device. For the sake of convenience, Figure 9 In the figure, the heating platform 10 is an induction cooker, and a second contact group 12 is provided on the bottom surface of the cookware body 21. The number of the second contacts 221 in the second contact group 12 is three for illustration.

[0177] In the present application, the cookware 20 may include a cookware body 21, at least one second contact group 22 and at least one function detection circuit 23 ( Figure 9 (not shown), each second contact group 22 is provided with at least two second contacts 221, and each function detection circuit 23 outputs a function signal.

[0178] Each second contact group 22 is disposed on the cookware body 21, providing a conductive contact for the cookware 20 to transmit signals to the heating platform 10. The present application does not limit the specific location of the second contact group 22 on the cookware body 21. Alternatively, the second contact group 22 can be disposed on the side of the cookware body 21, on the bottom surface of the cookware body 22, or embedded within the cookware body 22 and retractable for convenient connection. This application does not impose any restrictions on this. Furthermore, the present application does not impose any restrictions on the shape or material of the second contact group 22.

[0179] For example, the second contact group 22 can be set at the handle of the cookware 20. Since the cookware 20 generally has two handles, the user holds the cookware 20 with both hands, which makes it convenient for the user to accurately position the second contact group 22 through the handle of the cookware 20, thereby simplifying the user's operation and improving the user experience.

[0180] For another example, the second contact group 22 can be set at the bottom of the cookware 20, so that when the user places the cookware 20 on the heating platform 10, the second contact group 22 can contact the first contact group 12, thereby simplifying the user's operation.

[0181] Among them, the second contact group 22 can include two or two second contacts 221, so that the cookware 20 can transmit various types of signals to the heating platform 10 through the second contact 121. Each second contact 221 can transmit the same type of signal or a different type of signal. This application does not limit this. The signal can refer to the description of the aforementioned signal and will not be repeated here.

[0182] In addition, the second contact group 22 may include only the second contact 221, or may include the second contact 221 and other components that protect or secure the second contact 221. This application does not limit the specific implementation of the second contact group 22. In addition, when the second contact group 22 includes multiple second contacts 221, this application does not limit the signal transmission order or spacing between the multiple second contacts 221.

[0183] In the present application, each function detection circuit 23 outputs a function signal. Each function detection circuit 23 is electrically connected to one or more second contacts 221, so that the function detection circuit 23 transmits the detected function signal through the second contacts 221. The function detection circuit 23 may be an integrated chip, such as a temperature sensor or a pressure sensor, or a circuit composed of a combination of components, or a circuit composed of a combination of an integrated chip and components, and this application does not limit this.

[0184] In this application, the user places the cookware 20 on the heating platform 10, the heating platform 10 can be matched with the cookware 20, and one or more first contact groups 12 can be electrically contacted with the corresponding second contact groups 22 to achieve coupling between the first contact groups 12 and the second contact groups 22, so that the control circuit 13 receives multiple signals from one or more first contact groups 12, so that the control circuit 13 performs corresponding processing based on the multiple signals received.

[0185] Furthermore, while acquiring multiple signals, the control circuit 13 can also determine the characteristics of the signals. The characteristics of the signals can be used to indicate the type of functional signal among the multiple signals. Thus, the control circuit 13 can determine the type of functional signal received from the cookware 20 based on the characteristics of the signals. This allows the control circuit 13 to know the type of each signal, which helps the control circuit 13 accurately perform corresponding operations and avoids erroneous operations.

[0186] In one embodiment, one or more second contact groups 22 may be located on each side of the cookware body 21. In at least one second contact group 22 located on one side of the cookware body 21, in addition to the second contact 221 connected to the function detection circuit 23, there are one or more second contacts 221 not connected to the function detection circuit 23. In at least one second contact group 22 located on the other side of the cookware body 21, in addition to the second contact 221 connected to the function detection circuit 23, there are one or more second contacts 221 not connected to the function detection circuit 23. In at least one second contact group 22 located on one side of the cookware body 21, the one or more second contacts 221 not connected to the function detection circuit 23 are short-circuited with the one or more second contacts 221 not connected to the function detection circuit 23 in at least one second contact group 22 located on the other side of the cookware body 21.

[0187] When the heating platform 10 and the cookware 20 are matched, the second contact group 22 can be coupled to the first contact group 12, so that the short-circuited second contact 221 can short-circuit the first contact 121 in the first contact group 12. Therefore, the control circuit 13 determines the signal generated by the short-circuit connection of the first contact 121 as the prompt signal.

[0188] The present application does not limit the number of short-circuited second contacts 221. For example, any second contact 221 in each of the two second contact groups 22 can be short-circuited. The present application does not limit the positional relationship between the two short-circuited second contacts 221.

[0189] Optionally, the two second contacts 221 of the short-circuit connection are arranged axially symmetrically. Alternatively, the two second contacts 221 of the short-circuit connection are arranged asymmetrically.

[0190] For example, the cookware 20 includes two second contact groups 22, CN1 and CN2. Each second contact group 22 includes three second contacts 221, which are numbered 1, 2, and 3. The two second contact groups 22 are axially symmetrical.

[0191] If the two second contacts 221 of the short-circuit connection are axially symmetrically arranged, the two second contacts 221 of the short-circuit connection can be the two second contacts 221 of the short-circuit connection No. 1 in CN1 and the second contact 221 No. 1 in CN2, or the two second contacts 221 of the short-circuit connection No. 2 in CN1 and the second contact 221 No. 2 in CN2, or the two second contacts 221 of the short-circuit connection No. 3 in CN1 and the second contact 221 No. 3 in CN2.

[0192] If the two second contacts 221 of the short-circuit connection are set asymmetrically, the two second contacts 221 of the short-circuit connection can be the two second contacts 221 of the short-circuit connection No. 1 in CN1 and the second contact 221 No. 2 in CN2, or the two second contacts 221 of the short-circuit connection No. 2 in CN1 and the second contact 221 No. 1 in CN2, or the two second contacts 221 of the short-circuit connection No. 2 in CN1 and the second contact 221 No. 3 in CN2, or the two second contacts 221 of the short-circuit connection No. 3 in CN1 and the second contact 221 No. 2 in CN2.

[0193] In another embodiment, the second contact group 22 includes a preset second contact 221 for transmitting a prompt signal. When the cookware 20 is mated with the heating platform 10, the control circuit 13 can determine that the signal received by the first contact 221 coupled to the second contact 221 is a transmission prompt signal. Thus, the control circuit 13 can determine that the signal received from the first contact 121 coupled to the preset second contact 221 is a prompt signal.

[0194] The present application does not limit the type of the functional signal in the multiple signals. Optionally, the functional signal may include at least one of an overflow signal, a temperature signal, a water level signal, and a pressure signal.

[0195] Optionally, the type of functional signal transmitted by the second contact group 22 located on one side of the cookware body 21 is the same as the type of functional signal transmitted by the second contact group 22 located on the other side of the cookware body 21, so that the control circuit 13 can receive multiple functional signals of the same type at the same time, avoiding the problem of signal transmission failure due to poor contact of the contacts, and also allowing the control circuit 13 to accurately obtain this type of functional signal, so that the control circuit 13 can microscopically adjust the heating condition of the cookware by the heating platform 10.

[0196] Optionally, the type of functional signal transmitted by the second contact group 22 located on one side of the cookware body 21 is different from the type of functional signal transmitted by the second contact group 22 located on the other side of the cookware body 21, so that the control circuit 13 can receive different types of functional models at the same time, so that the control circuit 13 can fully grasp the current state of the cookware 30, so as to adjust the heating condition of the cookware 20 by the heating platform at a macro level.

[0197] The same type of functional signal is used to represent a property characteristic of the cookware 20. This application does not limit the detection position of the same type of functional signal. Optionally, the same type of functional signal is a signal detected from the same position and / or the same height of the cookware body 21. Alternatively, the same type of functional signal is a signal detected from different positions and / or different heights of the cookware body 21.

[0198] For example, assuming the functional signal is a temperature signal, then two signals obtained by detecting the temperature at the same position of the cookware body 21, that is, the two signals are of the same type and are both temperature signals. Two signals obtained by detecting the temperature at different positions of the cookware body 21, that is, the two signals are of the same type and are both temperature signals.

[0199] Those skilled in the art will appreciate that a grounding area is typically not provided on the cookware 20. Therefore, in this application, each functional signal is transmitted via two second contact points 221, one of which is a ground contact and the other is a functional contact. The ground contact is used to allow the heating platform 10 and the cookware 20 to share a common ground when the cookware 20 and the heating platform 10 are mated. The functional contact is used to transmit the functional signal.

[0200] Among them, the present application includes multiple settings for the ground contact.

[0201] Optionally, the ground contact corresponding to each functional signal is the same ground contact, that is, the ground contact of each functional detection circuit 23 is the same.

[0202] Optionally, each functional signal corresponds to a different ground contact. In other words, each functional detection circuit 23 is connected to a different ground contact. Figure 7 As shown, the temperature detection circuit N1 and the overflow detection circuit N2 are connected to different ground contacts.

[0203] Optionally, the grounding contacts of some function detection circuits 23 are the same grounding contact, and the grounding contacts of the remaining function detection circuits 23 are connected to different grounding contacts. Figure 8a As shown, the grounding contacts connected to the temperature detection circuit N1 and the overflow detection circuit N2 are different, while the grounding contacts connected to the temperature detection circuit N1 and the water level detection circuit N3 are the same.

[0204] Optionally, there is at least one multiplexing contact 221A in the second contact 221. For any multiplexing contact 221A, the multiplexing contact 221A can transmit different types of signals to achieve signal multiplexing. Among them, the present application does not limit the number and type of signals that can be transmitted by the multiplexing contact 221A. Optionally, all second contacts 221 are multiplexing contacts 121A, so that the number of signals that can be transmitted by the second contact 221 is maximized. Optionally, some second contacts 221 are multiplexing contacts 221A, which facilitates the design of the second contacts 221. In addition, the second contacts 221 arranged on both sides of the cookware body 21 can be arranged symmetrically with respect to the center, so that the second contact 221 can transmit multiple types of signals when used as a multiplexing contact 221A.

[0205] For example, when the second contact 221 is a multiplexing contact 221A, the multiplexing contact 221A can transmit signal 1 and signal 2. Alternatively, the multiplexing contact 221A can transmit signal 1, signal 2, and signal 3. Signal 1, signal 2, and signal 3 are different types of signals. Furthermore, for any two multiplexing contacts 221A, the signals that can be received by the two multiplexing contacts 221A can be of the same type or different types, and this application does not limit this.

[0206] Since the multiplexed contact 221A in the second contact group 22 can receive different types of signals, based on the second contact 221 in the first contact group 12, it can be matched with the second contact group 22 in the cookware 20, so that the cookware 20 can transmit various types of signals to the heating platform 10 through the second contact group 22, so that the heating platform 10 and the cookware 20 are successfully coupled, thereby reducing the number of conductive contacts.

[0207] The present application does not limit the number of second contacts 221 in the second contact group 22. Optionally, the number of second contacts 221 in each second contact group 22 may be the same or different.

[0208] The pot assembly provided in this application can be found in the above Figure 1-Figure 8a 、 Figure 8b The specific implementation principle and technical effects of the embodiment of the heating platform shown are not repeated here in this application.

[0209] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
