s101, when the heating platform is matched with the cookware, the control circuit obtains a plurality of signals based on the electrical contact of at least one first contact group and a corresponding second contact group in the cookware, and the plurality of signals comprise at least one functional signal.

In the present application, a user places a pot 20 on the heating platform 10, the heating platform 10 can be matched with the pot 20, one or more first contact sets 12 in the heating platform 10 can be electrically contacted with one or more corresponding second contact sets 22 in the pot 20, that is, one first contact set 12 in the heating platform 10 can be electrically contacted with one corresponding second contact set 22 in the pot 20, or a plurality of first contact sets 12 in the heating platform 10 can be electrically contacted with one or more corresponding second contact sets 22 in the pot 20, so as to realize the coupling between the first contact sets 12 and the second contact sets 22, so that the control circuit 13 receives a plurality of signals from one or more first contact sets 12, so that the control circuit 13 performs corresponding processing based on the received plurality of signals.

For example, when the control circuit 13 receives the temperature signal, the control circuit 13 may 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 the control circuit controls the heating platform 10 to continue heating the pot 20 due to detecting that the temperature is too low, and so on.

The number of the plurality of signals may be two or more, and the types of the plurality of signals may include a functional signal and a hint signal, that is, the plurality of signals may include one or more functional signals and one or more other signals. The function signal is used to indicate the property of the pot 20, and is usually detected by the pot 20 through a sensor or other detecting component. The specific representation of the functional signal is not limited in this application. Optionally, the functional signal may include: at least one of an overflow signal, a temperature signal, a water level signal, and a pressure signal. Wherein, the overflow signal is used to indicate whether the food in the pot 20 has the overflow phenomenon. The temperature signal may be a temperature of an inner surface of the pot 20, may also indicate a temperature of an outer surface of the pot 20, may also be an average temperature of the pot 20, may also be a temperature of a bottom of the pot 20, may also be a temperature of a sidewall of the pot 20, and is not limited in this application. The pressure signal is used to indicate the pressure level of the pot 20. The water level signal is used to indicate the height of the food in the pot 20 in the pot. The indication signal is used to indicate that the pot 20 is successfully coupled to the heating platform 10, such as a coupling signal. The prompt signal can be a digital signal or an analog signal, and the specific implementation form of the prompt signal is not limited in the application.

It should be noted that the types of the signals acquired by the control circuit 13 may only include the function signal, or may include the function signal and the prompt signal, which is not limited in this application.

S102, the control circuit determines the type of the function signal received from the cooker based on the characteristics of the signal.

In this application, the control circuit 13 may determine a characteristic of the signal while acquiring the plurality of signals, and the characteristic of the signal may be used to indicate a type of the functional signal in the plurality of signals. Therefore, the control circuit 13 can determine the type of the function signal received from the cooker 20 based on the characteristics of the signal, so that the control circuit 13 can know the type of each signal, the control circuit 13 can accurately perform corresponding operation, and misoperation is avoided.

The application provides a signal processing method, through when heating platform and pan match, based on one or more first contact group in the heating platform and the corresponding second contact group electrical contact in the pan, control circuit in the heating platform can obtain a plurality of signals, and wherein a plurality of signals include at least one function signal. Since the characteristics of the signal may be used to indicate the type of function signal in the plurality of signals, the control circuit may determine the type of function signal received from the cookware based on the characteristics of the signal. Therefore, the heating platform can accurately acquire the attribute characteristics of the cookware through accurately acquiring the type of each signal, the heating platform can comprehensively know the current state of the cookware, the operation corresponding to the type of the signal can be timely made, and the linkage effect between the heating platform and the cookware is realized.

In addition to the embodiments shown in fig. 1-2, in the present application, a characteristic of a signal may indicate a type of one or more signals, may also indicate a number of signals, may also indicate a location of one or more signals, may also indicate a serial number of one or more signals, may also indicate any combination of the foregoing manners, and the present application is not limited thereto.

In the following, a specific implementation process of determining the type of the function signal received from the cooker 20 by the control circuit 103 based on the characteristics of the signal in S102 is illustrated by combining two possible implementations.

In a possible implementation, the control circuit 13 may store in advance a correspondence between the number of signals and the type of signals. The correspondence may be stored in various ways such as a table, a number sequence, and a matrix, which is not limited in this application, and may be set according to the number of signals actually transmitted on any one cookware 20, or according to the number of signals transmitted by cookware 20 of different types in the types of cookware 20 that the heating platform 10 can be matched with, or according to a combination of the two ways.

Thus, the control circuit 13 can determine the number of signals received from the pot 20 based on the characteristics of the signals, so that the control circuit 13 determines the type of function signal received from the pot 20 according to the correspondence between the number of signals and the type of signals.

For example, assuming that the number of signals is 1, the type of signal includes a temperature signal; the number of signals is 2, and the types of signals include temperature signals and pressure signals. Thus, when the number of signals received by the control circuit 13 is 2, the control circuit 13 may determine that the type of function signal received from the pot 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.

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

In addition, when the heating platform 10 can be matched with a plurality of types of pots 20, the control circuit 13 can also store the corresponding relationship between the number of signals and the types of pots in advance. The corresponding relationship may adopt various storage modes such as a table, a number column, a matrix and the like, which is not limited in this application. Therefore, 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 determines the type of the cookware 20 according to the corresponding relation between the number of the signals and the type of the cookware, not only can distinguish the type of the cookware 20 matched with the heating platform 10 to realize the precise control of the heating platform 10, but also can distinguish the coupling state that any cookware 20 which can adopt various matching positions is placed on the heating platform 10, such as forward or reverse placement. Wherein, the matching position is used for representing the coupling state of the pot 20 and the heating platform 10 for signal transmission.

For example, referring to fig. 3, for convenience of illustration, in fig. 3, the number of the first contact sets 12 in the heating platform 10 is illustrated as two, the number of the first contacts 121 in each first contact set 12 is illustrated as three, fig. 3 includes two types of pots 20, respectively a stew pot a and a soup pot B, one second contact set 22 is disposed on one side of each pot 20, and the second contact set 22 includes three second contacts 221.

Assuming a correspondence between the number of signals and the type of cookware: the number of signals is 1, the type of pot 20 is saucepan a; the number of signals is 2 and the type of pot 20 is soup pot B. As shown in fig. 3, when the number of signals received by the control circuit 13 is 1 when the pot 20 is placed on the heating platform 10, the control circuit 13 can determine that the type of the pot placed on the heating platform 10 is stewpot a, so that the control circuit 13 performs corresponding operations. When the number of signals received by the control circuit 13 is 2, the control circuit 13 can determine that the type of the pot placed on the heating platform 10 is the stockpot B, so that the control circuit 13 can perform corresponding operations.

Based on the above description, when the heating platform 10 includes a first contact set 12, the control circuit 13 can accurately determine the type of the function signal transmitted by the second contact set 22 matching with the first contact set 12, so that the control circuit 13 can accurately determine the type of the function signal transmitted by the plurality of second contact sets 22 in the pot 20 through the change of the matching position (i.e. the coupling state of the pot 20). By doing so, conveniently select this first contact group 12 on different second contact group 22 and the heating platform 10 in the pan 20 according to actual demand and match for control circuit 13 can acquire the function signal that wants to acquire, and then makes control circuit 13 in time know the attribute characteristic of pan 20, makes things convenient for control circuit 13 to carry out corresponding adjustment.

When two or more first contact sets 12 are included on the heating platform 10, the control circuit 13 may determine the number of signals received from each of the plurality of first contact sets 12 based on the characteristics of the signals, so that the control circuit 13 determines the type of the function signal transmitted by the second contact set 22 matched with each first contact set 12, so that the control circuit 13 can accurately determine the type of the function signal transmitted by the plurality of second contact sets 22 in the pot 20. By doing so, conveniently select different second contact group 22 in pan 20 and match with a plurality of first contact group 12 on the heating platform 10 according to actual demand for control circuit 13 can acquire the function signal that wants to acquire, and then makes control circuit 13 in time know the attribute characteristic of pan 20, makes things convenient for control circuit 13 to carry out corresponding adjustment.

Alternatively, when a plurality of first contact sets 12 are located on both sides of the heating stage body 11, the control circuit 13 may determine a first number of signals received from the first contact set 12 located on one side of the heating stage body 11 and a second number of signals received from the first contact set 12 located on the other side of the heating stage body 11. Since the control circuit 13 stores the corresponding relationship between the number and the type of the signal in advance, when the first number is different from the second number, the control circuit 13 may compare the corresponding relationship between the number and the type of the signal, and determine the type of each function signal obtained from the corresponding first contact group on any side of the heating platform body 11, thereby determining the type of the function signal received from the cookware.

In addition to the above, the control circuit 13 may store a correspondence relationship between the number and the signal arrangement order in advance. The corresponding relationship may adopt various storage modes such as a table, a number column, a matrix and the like, which is not limited in this application. Thus, the control circuit 13 compares the correspondence between the number and the arrangement order of the signals, and can determine the positional relationship of each functional signal.

For example, assume a correspondence relationship between the number of signals and the arrangement order of the signals: the number of the signals is 2, and the signals are arranged in sequence of temperature signals and pressure signals from any side of the heating platform body 11; the number of signals is 2, and from the side of the heating platform body 11, the signals are arranged in order of a temperature signal, a pressure signal, and a water level signal. Thus, when the number of signals received by the control circuit 13 is 2, the control circuit 13 may determine the arrangement order of the signals as the temperature signal and the pressure signal so that the control circuit 13 performs the corresponding operation.

In addition, the control circuit 13 may also store the corresponding relationship between the number and the coupling state of the cookware in advance. The corresponding relationship may adopt various storage modes such as a table, a number column, a matrix and the like, which is not limited in this application. Therefore, when the first quantity is different from the second quantity, the control circuit 13 can determine the positive successful coupling or the negative successful coupling of the heating platform 10 and the cookware 20 by comparing the corresponding relation between the quantity and the coupling state of the cookware, and can prompt the user that the heating platform 10 and the cookware 20 are successfully coupled or coupled, if a display screen on the heating platform body 11 displays corresponding characters to the user or light with different colors on the heating platform body 11 is adopted to prompt the user correspondingly, the two processes can be executed, and the application does not limit the process.

Like this, when the user is placing pan 20 on heating platform 10, need not to consider pan 20's front or reverse side, all can realize pan 20's front or reverse side and heating platform 10's successful coupling, be favorable to simplifying and convenience of customers ' operation, improved user's use and felt.

For example, referring to fig. 4, for convenience of illustration, in fig. 4, the number of the first contact sets 12 in the heating platform 10 is illustrated as two, the number of the first contacts 121 in each first contact set 12 is illustrated as three, and in fig. 4, the pot 20 is provided with one second contact set 22 on each side of the pot 20, wherein one second contact set 22 includes three second contacts 221 for transmitting one function signal, and the other second contact set 22 includes four second contacts 221 for transmitting two function signals.

Assuming a correspondence between the number of signals and the coupling state of the cookware: the number of the signals is 1, and the coupling state of the cookware is the front; the number of signals is 2, and the coupling state of the cookware is the reverse side. As shown in fig. 4, when the number of the function signals received by the control circuit 13 is 1, the control circuit 13 can determine that the pot 20 is being placed on the heating platform 10, that is, the heating platform 10 and the pot 20 are successfully coupled, so that the control circuit 13 performs the corresponding operation. When the number of the function signals received by the control circuit 13 is 2, the control circuit 13 can determine that the pot 20 is reversely placed on the heating platform 10, that is, the heating platform 10 is successfully coupled with the reverse side of the pot 20, so that the control circuit 13 performs corresponding operations.

In another possible implementation, the control circuit 13 may determine the types of the plurality of signals based on the plurality of signals received. When the control circuit 13 determines that the plurality of signals includes one or more alert signals and one or more function signals, since the alert signals can be used to indicate the successful coupling between the heating platform 10 and the pot 20, the control circuit 13 can determine the characteristics of the alert signals such as the number, position, or serial number, so that the control circuit 13 can determine the type of the function signal in the plurality of signals, i.e., determine the type of the function signal received from the pot 20.

For example, assuming that the number of cue signals is 1, the type of function signal includes a temperature signal; the number of cue signals is 2 and the types of function signals include temperature signals and pressure signals. Thus, when the number of the prompt signals received by the control circuit 13 is 2, the control circuit 13 can determine that the type of the function signal received from the pot 20 includes a temperature signal and a pressure signal, so that the control circuit 13 performs respective operations corresponding to the temperature signal and the pressure signal.

For another example, assuming that the prompt signal is located on the side a of the heating platform body 11, the type of the function signal includes a temperature signal; the prompt signal is located on the side B of the heating platform body 11, and the types of the function signals comprise a temperature signal and a pressure signal. Therefore, when the prompting signal received by the control circuit 13 is located on the side a of the heating platform body 11, the control circuit 13 can determine that the type of the function signal received from the pot 20 includes a temperature signal, so that the control circuit 13 performs an operation corresponding to the temperature signal.

Alternatively, the control circuit 13 may determine that the cue signal corresponds to the position of the first contact 121 in the first contact set 12, so that the control circuit 13 determines the type of the function signal corresponding to the first contact 121 in the rest positions based on the position.

The type of the function signal correspondingly included in any position is stored in the control circuit 13 in advance, and the type may be stored in a form of a table or a list, which is not limited in the present application. For the convenience of storage, the control circuit 13 may store the correspondence between the sequence number and the position in advance so that the control circuit 13 determines the position corresponding to the presentation signal based on the sequence number of the presentation signal.

The first contact group 12 is provided with one or more first contacts 121, each first contact 121 is used for conducting electricity to implement receiving or sending of a signal, and specifically, a conductive material such as a metal may be used. The number of the first contacts 121 in each first contact group 12 may be the same or different, and is not limited in this application. The first contact set 12 may only include the first contact 121, and may also include the first contact 121 and other components that protect or fix the first contact 121, and the like, and the specific implementation form of the first contact set 12 is not limited in this application. In addition, when the first contact group 12 includes a plurality of first contacts 121, the present application does not limit the signal transmission order and the spacing between the plurality of first contacts 121.

In addition, when the heating platform 10 includes at least two first contact sets 12, the heating platform 10 and any one of the pots 20 have at least two matching positions, and a signal can be transmitted between the heating platform 10 and any one of the pots 20 at each matching position, the control circuit 13 may also store a corresponding relationship between the position and the coupling state of the pot in advance. The corresponding relationship may adopt various storage modes such as a table, a number column, a matrix and the like, which is not limited in this application.

Therefore, the control circuit 13 can determine the successful positive coupling or the successful negative coupling of the heating platform 10 and the cookware 20 by comparing the corresponding relationship between the positions and the coupling states of the cookware, and can also prompt the user that the heating platform 10 and the cookware 20 are successfully coupled positively or negatively, if a display screen on the heating platform body 11 displays corresponding characters for the user or lights with different colors on the heating platform body 11 are used for carrying out corresponding prompt for the user, the two processes can be carried out, and the application does not limit the processes.

In this way, the heating platform 10 can distinguish the coupled state that any one pot 20 can be placed on the heating platform 10 in any one of a plurality of matching positions, such as right side or reverse side. Moreover, when the user places the pot 20 on the heating platform 10, the front or the back of the pot 20 can be successfully coupled with the heating platform 10 without considering the front or the back of the pot 20, so that the pot is easy to simplify and convenient for the user to operate, and the use feeling of the user is improved.

For example, referring to fig. 5, for convenience of illustration, in fig. 5, the number of the first contact sets 12 in the heating platform 10 is illustrated as two, the number of the first contacts 121 in each first contact set 12 is illustrated as three, and in fig. 5, the pot 20 is provided with one second contact set 22 on each side of the pot 20, and each second contact set 22 includes three second contacts 221, which may be used for transmitting one or two function signals.

Assuming a correspondence between the position and the coupling state of the cookware: the prompting signal is positioned at the side A of the heating platform body 11, and the coupling state of the cookware is the front; the position of the prompt signal is located on the side B of the heating platform body 11, and the coupling state of the cookware is the reverse side. As shown in fig. 5, when the control circuit 13 determines that the position of the prompting signal is located on the side a of the heating platform body 11, the control circuit 13 can determine that the pot 20 is being placed on the heating platform 10, that is, the heating platform 10 and the pot 20 are successfully coupled with each other, so that the control circuit 13 performs corresponding operations. When the control circuit 13 determines that the position of the prompting signal is located on the side B of the heating platform body 11, the control circuit 13 may determine that the pot 20 is reversely placed on the heating platform 10, that is, the heating platform 10 and the pot 20 are successfully coupled with each other on the reverse side, so that the control circuit 13 performs corresponding operations.

In this application, the method for the control circuit 13 to obtain the prompt signal includes various methods. In the following, three implementation manners are used to exemplify a specific process of the control circuit 13 for acquiring the prompt signal.

In one embodiment, if any one of the second contacts 221 of the at least one second contact group 22 located on both sides of the pot 20 except the second contact 221 corresponding to the function signal is short-circuited, and when the heating platform 10 is matched with the pot 20, the second contact group 22 can be correspondingly coupled with the first contact group 12, so that the short-circuited second contact 221 can short-circuit the first contact 121 of the first contact group 12. Thus, the control circuit 13 determines the signal generated from the short-circuiting of the first contact 121 as the cue signal.

The second contact group 22 may include one or more second contacts 221, each second contact 221 is used for conducting to receive or transmit a signal, and specifically, a conductive material such as a metal may be used. The second contact set 22 may only include the second contact 221, or may include the second contact 221 and other components that protect or fix the second contact 221, and the application does not limit the specific implementation form of the second contact set 22. In addition, when the second contact group 22 includes a plurality of second contacts 221, the present application does not limit the signal transmission order and the spacing between the plurality of second contacts 221.

In another embodiment, if the second contact 221 dedicated to transmitting the prompting signal is preset in the second contact group 12, when the pot 20 is matched with the heating platform 10, the control circuit 13 may determine that the signal received by the first contact 221 coupled with the second contact 221 is the transmission prompting signal. Thus, the control circuit 13 may determine a signal received from the first contact 121 coupled with the preset second contact 221 as the cue signal.

In another embodiment, if the first contact set 12 is pre-set with a first contact 121 dedicated to receiving the prompting signal, the pot 20 sets a second contact 221 coupled with the first contact 121 to transmit the prompting signal when matching with the heating platform 10. Thus, the control circuit 13 may determine a signal received from the preset first contact 121 as the cue signal.

Optionally, all of the first contacts 121 are multiplexing contacts 121A such that the number of signals receivable by the first contacts 121 is maximized. Optionally, a portion of the first contacts 121 are multiplexing contacts 121A, facilitating the design of the first contacts 121. In addition, the first contacts 121 disposed at both sides of the heating stage body 11 may be disposed in central symmetry so that the first contacts 121 can transmit a plurality of types of signals when they are the multiplexing contacts 221A.

For example, when the first contact 121 is the multiplexing contact 121A, the multiplexing contact 121A may receive the signal 1 and may also receive the signal 2.

And the specific position of the second contact group 22 on the pot body 21 is not limited by the present application. Optionally, the second contact group 22 may be disposed on a side surface of the pot body 21, or disposed on a bottom surface of the pot body 22, or embedded in the pot body 22 and may be retractable for convenient connection, which is not limited in this application. In addition, the shape and material of the second contact group 22 are not limited in the present application.

As another example, the second contact set 22 may be disposed at the bottom of the pot 20, so that when the user places the pot 20 on the heating platform 10, the second contact set 22 may contact the first contact set 12, thereby simplifying the operation of the user.

The second contact group 22 may include two or two second contacts 221, so that the pot 20 may transmit various types of signals to the heating platform 10 through the second contacts 121, and each second contact 221 may transmit the same type of signal or different types of signals.

In addition, the second contact group 22 may only include the second contact 221, or may include the second contact 221 and other components that protect or fix the second contact 221, and the application does not limit the specific implementation form of the second contact group 22. In addition, when the second contact group 22 includes a plurality of second contacts 221, the present application does not limit the signal transmission order and the spacing between the plurality of second contacts 221.

In the present application, each function detection circuit 23 outputs a function signal. Each function detecting circuit 23 is electrically connected to one or more second contacts 221 so that the function detecting 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 formed by combining components, or a circuit formed by combining an integrated chip and components, which is not limited in this application.

In this application, a user places a pot 20 on the heating platform 10, the heating platform 10 can be matched with the pot 20, and one or more first contact sets 12 can be electrically contacted with corresponding second contact sets 22 to realize the coupling between the first contact sets 12 and the second contact sets 22, so that the control circuit 13 receives a plurality of signals from one or more first contact sets 12, and the control circuit 13 performs corresponding processing based on the received plurality of signals.

In one embodiment, one or more second contact sets 22 may be located on each side of the pot body 21. In at least one second contact group 22 located at one side of the pot body 21, there are one or more second contacts 221 not connected to the function detecting circuit 23 in addition to the second contacts 221 connected to the function detecting circuit 23. In the at least one second contact group 22 located at the other side of the pot body 21, there are one or more second contacts 221 not connected to the function detecting circuit 23 in addition to the second contacts 221 connected to the function detecting circuit 23. One or more second contacts 221, which are not connected with the function detection circuit 23, of the at least one second contact group 22 located at one side of the pot body 21, and one or more second contacts 221, which are not connected with the function detection circuit 23, of the at least one second contact group 22 located at the other side of the pot body 21, are set to be in short-circuit connection.

When the heating platform 10 is mated with the pot 20, the second contact set 22 may be correspondingly coupled with the first contact set 12, so that the short-circuited second contact 221 may short-circuit the first contact 121 in the first contact set 12. Thus, the control circuit 13 determines the signal generated from the short-circuiting of the first contact 121 as the cue signal.

The number of the second contacts 221 to be short-circuited is not limited in the present application. For example, any one of the second contacts 221 in each of the two second contact groups 22 is short-circuited. The present application does not limit the positional relationship between the two second contacts 221 that are short-circuited.

Alternatively, the two second contacts 221 of the short-circuit connection are arranged axisymmetrically. Alternatively, the two second contacts 221 of the short-circuit connection are arranged asymmetrically.

For example, two second contact sets 22, CN1 and CN2, are included in the pot 20. Each second contact group 22 includes three second contacts 221, and the serial numbers of the three second contacts 221 are No. 1, No. 2, and No. 3, respectively. And the two second contact sets 22 are arranged axisymmetrically.

If the two second contacts 221 of the short circuit connection are disposed axisymmetrically, the two second contacts 221 of the short circuit connection may be the two second contacts 221 of the short circuit connection No. 1 in CN1 and the second contact 221 No. 1 in CN2, the two second contacts 221 of the short circuit connection No. 2 in CN1 and the second contact 221 No. 2 in CN2, the two second contacts 221 of the short circuit connection No. 3 in CN1 and the second contact 221 No. 3 in CN 2.

If the two second contacts 221 of the short circuit connection are arranged asymmetrically, the two second contacts 221 of the short circuit connection may be the two second contacts 221 of the short circuit connection No. 1 in CN1 and the second contact 221 No. 2 in CN2, the two second contacts 221 of the short circuit connection No. 2 in CN1 and the second contact 221 No. 1 in CN2, the two second contacts 221 of the short circuit connection No. 2 in CN1 and the second contact 221 No. 3 in CN2, and the two second contacts 221 of the short circuit connection No. 3 in CN1 and the second contact 221 No. 2 in CN 2.

In another embodiment, a preset second contact 221 for transmitting the prompting signal is arranged in the second contact group 22. When the pot 20 is matched with the heating platform 10, the control circuit 13 may determine that the signal received by the first contact 221 coupled with the second contact 221 is a transmission prompting signal. Thus, the control circuit 13 may determine a signal received from the first contact 121 coupled with the preset second contact 221 as the cue signal.

The present application does not limit the type of the functional signal in the plurality of 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.

Optionally, the type of the function signal transmitted by the second contact group 22 located on one side of the pot body 21 is the same as the type of the function signal transmitted by the second contact group 22 located on the other side of the pot body 21, so that the control circuit 13 can receive a plurality of function signals of the same type at the same time, thereby avoiding the problem of signal transmission failure caused by poor contact of the contacts, and also enabling the control circuit 13 to accurately obtain the type of function signal, so that the control circuit 13 can microscopically adjust the heating condition of the heating platform 10 on the pot.

Optionally, the type of the function signal transmitted by the second contact group 22 located on one side of the pot body 21 is different from the type of the function signal transmitted by the second contact group 22 located on the other side of the pot body 21, so that the control circuit 13 can receive different types of function models at the same time, and the control circuit 13 can comprehensively grasp the current state of the pot 30, so as to adjust the heating condition of the heating platform on the pot 20 macroscopically.

Wherein the same type of function signal is used to represent one attribute characteristic of the cookware 20. The present application does not limit the detection positions of the same type of functional signals. Optionally, the same type of function signal is a signal detected from the same position and/or the same height of the pot body 21. Alternatively, the same type of function signal is a signal detected from different positions and/or different heights of the pot body 21.

For example, assuming that the function signal is a temperature signal, two signals obtained by detecting the temperature from the same position of the pot body 21, i.e., the two signals are of the same type and are both temperature signals. Two signals obtained by detecting the temperature from different positions of the pot body 21, namely, the two signals are of the same type and are both temperature signals.

It will be appreciated by those skilled in the art that generally no ground contact area is provided on the pot 20. Thus, in the present application, each functional signal is transmitted by two second contact points 221, wherein one second contact point 221 is a ground contact and the other second contact point 221 is a functional contact. The ground contact is used to ground the heating platform 10 and the pot 20 when the pot 20 and the heating platform 10 are mated. The functional contact is used for transmitting functional signals.

The arrangement of the grounding contact includes various arrangements.

Optionally, the ground contact corresponding to each functional signal is the same ground contact. That is, the ground contact of each function detection circuit 23 is the same.

Optionally, the ground contact for each functional signal is different. That is, the ground contact to which each function detection circuit 23 is connected is different. As shown in fig. 7, the temperature detection circuit N1 and the overflow detection circuit N2 are connected to different ground contacts.

Alternatively, the ground contacts of some of the function detection circuits 23 are the same ground contact, and the ground contacts to which the ground contacts of the remaining function detection circuits 23 are connected are different ground contacts. As shown in fig. 8a, the temperature detection circuit N1 and the overflow detection circuit N2 are connected to different ground contacts. The temperature detection circuit N1 and the water level detection circuit N3 are connected to the same ground contact.

Optionally, there is at least one multiplexing contact 221A in the second contacts 221. For any one multiplexing contact 221A, the multiplexing contact 221A can transmit different types of signals to realize multiplexing of signals. The number and types of signals that multiplexing contact 221A can transmit are not limited in the present application. Optionally, all of the second contacts 221 are multiplexing contacts 121A such that the number of signals that can be transmitted by the second contacts 221 is maximized. Optionally, a portion of the second contacts 221 are multiplexing contacts 221A, which facilitates the design of the second contacts 221. In addition, the second contacts 221 disposed at both sides of the pot body 21 may be disposed in central symmetry so that the second contacts 221 can transmit a plurality of types of signals when they are the multiplexing contacts 221A.

For example, when the second contact 221 is a multiplexing contact 221A, the multiplexing contact 221A may transmit signal 1 and may also transmit signal 2. Alternatively, the multiplexing contact 221A may transmit signal 1, signal 2, or signal 3. Where signal 1, signal 2, and signal 3 are different types of signals. In addition, for any two multiplexing contacts 221A, the signals receivable by the two multiplexing contacts 221A may be of the same type or of different types, which is not limited in this application.

Since the multiplexing contacts 221A in the second contact set 22 can receive different types of signals, matching with the second contact set 22 in the pot 20 can be achieved based on the second contacts 221 in the first contact set 12, so that the pot 20 can transmit various types of signals to the heating platform 10 through the second contact set 22, so that the heating platform 10 and the pot 20 are successfully coupled, thereby reducing the number of conductive contacts.

The number of the second contacts 221 in the second contact group 22 is not limited in the present application. Alternatively, the number of second contacts 221 in each second contact set 22 may be the same or different.

The pot assembly provided by the application can refer to the embodiments of the heating platform shown in fig. 1-8 a and 8b, and the specific implementation principle and technical effect are not repeated herein.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
