Correspondingly, after the step 101, the method may further include: and 103, judging whether the identity information accords with the identity information stored in the electric heating device in advance by the electric heating device.

Wherein, the identity information that preserves in advance in the electric heater unit can be the identity information of the matching pan that preserves when confirming pan and electric heater unit match last time. According to the identity information that electric heater unit preserved in advance, judge the identity information in the wireless signal of pan, can make the judgement fast, whether this signal sends for the pan that matches.

301. the induction cooker receives wireless information sent by the cookware, and the wireless information carries the identification of the cookware.

Wherein, wireless information can also include the temperature data that the pan detected the pan through temperature collector. The temperature data of the pot can be temperature data of the bottom of the pot or temperature data of liquid, gas or solid inside the pot. The temperature collector can be a temperature sensor or other devices capable of detecting temperature. The identification of the cookware is a code which can uniquely identify the cookware, and the like.

302. The work state of the induction cooker is judged.

Wherein, the working state of the induction cooker can comprise: a heating stop state, a power-out heating state, a pot lifting state and a standby state. Wherein, the heating stop state is the state that the induction cooker is started up and a cooker is arranged on the induction cooker but the induction cooker does not heat the induction cooker; the power output heating state is a state that the induction cooker is started up and is provided with a cooker and is heated by the induction cooker; the pot lifting state is a state after a pot on the induction cooker is lifted in a power-out heating state, and in the state, the induction cooker is started, no pot is arranged on the induction cooker, and the induction cooker does not heat the induction cooker; the standby state is a state when the induction cooker is in standby.

The heating stop state and the power output heating state are determined by the induction cooker with the cooker according to the self-hot starting switch state. The pot lifting state is determined by the induction cooker according to the pressure value detected by the pressure sensor on the surface of the oven. If the cooker placed on the induction cooker is lifted away under the condition that the induction cooker is in the power-out heating state, the working state of the induction cooker is changed into the cooker lifting state by the induction cooker according to the pressure signal fed back by the pressure sensor.

Specifically, if the induction cooker does not receive the wireless information sent by the pot after stopping heating operation and receives the wireless information sent by the pot after performing power-out heating operation, the induction cooker can determine that the heated pot is placed on the induction cooker, which indicates that the pot is matched with the induction cooker, and the induction cooker can heat the pot in a precise control mode.

Further, since a certain time is required for the alternating magnetic field of the pot and the rectifier capacitor of the electromagnetic coil to decay, and the pot may periodically send the wireless information when the electromagnetic coil is powered on, step 304 may specifically be that if the electromagnetic oven does not receive the wireless information within a first preset time period after the heating operation is stopped, and receives the wireless information within a second preset time period after the power-off heating operation is performed, the electromagnetic oven determines that the identifier is an effective identifier, and performs the precise control mode heating on the pot according to the effective identifier.

The first preset time period can be longer than decay time of the alternating magnetic field of the pot and the rectification capacitor of the electromagnetic coil. The second preset time period can be longer than the stabilization time of the alternating magnetic field and the electromagnetic coil rectification capacitor of the cooker and shorter than the sum of the stabilization time of the alternating magnetic field and the electromagnetic coil rectification capacitor of the cooker and the fixed period of the wireless information transmitted by the cooker. It should be noted that, correspondingly, in step 303, the time interval between the heating stopping operation and the power output heating operation performed by the induction cooker needs to be greater than or equal to the length of the first preset time period.

In this embodiment, the induction cooker carries the identification of the pan through receiving the wireless information that the pan sent, if the state of induction cooker is the power-out heating state, then the induction cooker stops heating operation and power-out heating operation in proper order, if the induction cooker does not receive wireless information after stopping heating operation, and receive wireless information after heating operation, then the induction cooker confirms that the identification is effective identification, carry out the heating of accurate control mode to the pan according to effective identification, thereby realize according to the operating condition of induction cooker, and whether the induction cooker receives wireless information in stopping heating and power-out heating process and carry out validity judgement to the identification of pan, match induction cooker and pan before avoiding dispatching from the factory, improve production efficiency.

Fig. 4 is a flowchart of another embodiment of a pot heating control method provided by the present invention, as shown in fig. 4, on the basis of the embodiment shown in fig. 3, before step 303, the method may further include:

305. the induction cooker judges whether the preset invalid identity list comprises the identification of the cookware.

After the induction cooker determines that the identification is the invalid identification, the invalid identity list can be updated according to the invalid identification.

If the invalid identity list includes the identity of the cookware, execute step 306: and the induction cooker determines that the mark is an invalid mark, and heats the cookware on the induction cooker in a non-precise control mode.

If the invalid identity list does not include the identity of the cookware, execute step 303: the induction cooker performs heating stop operation and power output heating operation in sequence.

Further, if the state of the induction cooker is changed from the power-out heating state to the pot-lifting state, the pot placed on the induction cooker may be moved away, or replaced with another pot, for example, the pots on another induction cooker are exchanged with the pot on the induction cooker, which may result in the change of the pot matched with the induction cooker. That is to say, after the state information of the induction cooker is changed from the power-out heating state to the pot-lifting state, the previous invalid identifier for the induction cooker may be valid at this time, and therefore, after the induction cooker heats the pot in the fine control mode according to the valid identifier, if the working state of the induction cooker is changed to the pot-lifting state, the induction cooker may clear the invalid identifier list.

In the embodiment, the induction cooker receives the wireless information sent by the cooker, the wireless information carries the identification of the cooker, if the state of the induction cooker is the power-out heating state, the induction cooker judges whether the preset invalid identity list comprises the identification of the cooker, if the invalid identity list comprises the identification of the cooker, the induction cooker determines that the identification is the invalid identification, and the cooker on the induction cooker is heated in a non-precise control mode; if the invalid identity list does not comprise the identification of the cookware, the induction cooker sequentially stops heating operation and power-out heating operation, if the induction cooker does not receive wireless information after the heating operation is stopped, and receives the wireless information after the power-out heating operation, the induction cooker determines that the identification is an effective identification, and carries out precise control mode heating on the cookware according to the effective identification, so that validity judgment on the identification of the cookware is carried out according to the state of the induction cooker and whether the induction cooker receives the wireless information in the processes of stopping heating and power-out heating, the induction cooker and the cookware are prevented from being matched before delivery, and the production efficiency is improved.
