[0092] The calibration device 200 has wireless communication function. Specifically, the calibration device 200 is provided with a calibration-end wireless transmission device 70, which can be, for example, a WI-FI module or a Bluetooth module. Of course, the wireless transmission device can also be a functional module based on other wireless communication technologies, which are not limited in the present application. It can be understood that the calibration-end wireless transmission device 70 of the calibration device 200 should be matched with the product-end wireless transmission device 50 of the cooking utensil 100. To realize the power calibration function, the calibration device 200 further comprises a calibration module 60 and a setting module 61. The calibration module 60 runs a calibration software for controlling the calibration device 200 and completing the power calibration function, and simultaneously serves as the processor of the calibration device 200. The calibration module 60 is electrically connected with the calibration-end wireless transmission device 70 and the setting module 61. The setting module 61 is used to realize parameter setting of the calibration device 200. In the preferred embodiment, the calibration device 200 of the cooking utensil 100 according to the present application can be a special device specially used for implementing the power calibration function, or can be realized by relying on a device having a wireless communication module and a processing module, such as a civil or industrial intelligent terminal installed with the calibration software, including a desktop computer, a notebook computer, an industrial computer, a tablet computer, a mobile phone, etc.

[0093] ​The power metering device 300 is preferably a digital power meter, used to measure the actual power of the cooking appliance 100. The power metering device 300 has wireless transmission capabilities. Specifically, the power metering device 300 includes a metering-end wireless transmission device 80, which can be, for example, a Wi-Fi module or a Bluetooth module. Of course, this wireless transmission device can also be a functional module based on other wireless communication technologies; this invention is not limited thereto. It is understood that the metering-end wireless transmission device 80 of the power metering device 300 should be matched with the calibration-end wireless transmission device 70 of the calibration device 200.

[0094] Specifically, when using a power meter to measure the actual power of a cooking appliance, the power meter is connected to the mains power network, and the power input terminal of the cooking appliance is connected to the power output terminal of the power meter. The cooking appliance is electrically connected to the power meter and powered by the power meter, so the power meter can measure electrical parameters such as the power consumption, operating voltage, and operating current of the cooking appliance, and thus can measure the actual power of the cooking appliance.

[0095] The power calibration method for the cooking appliance 100 of the present invention involves obtaining the rated power value P0, the actual power value P1, and the self-collected power value P2 of the cooking appliance 100, and then determining the power calibration parameter C, where C = P2 + P1 / P2 × (P0 - P1). When the cooking appliance 100 is heating, adjusting the working power value to this value C will achieve the actual working power being equal to the rated power value.

[0096] The following combination Figure 3 The working process of the cooking system 500 according to the present invention is described, that is, the process by which the calibration system 400 performs power calibration on the cooking appliance 100.

[0097] During the power calibration process, the power metering device 300 is always electrically connected to the cooking appliance 100 to measure the actual working power of the cooking appliance 100 in real time.

[0098] The cooking appliance 100 includes a calibration button among its function buttons 30 for initiating the power calibration process. This calibration button can be a dedicated button or can be activated through a combination of other buttons. After the user presses this calibration button, the control device 40 of the cooking appliance 100 initiates the power calibration process.

[0099] First, the control device 40 controls the product-side wireless transmission device 50 to send a first signal, also known as a handshake signal, to the calibration device 200 to establish wireless communication. Specifically, the product-side wireless transmission device 50 sends the first signal to the calibration-side wireless transmission device 70 of the calibration device 200.

[0100] After the first signal from the cooking appliance 100 is received by the calibration end wireless transmission device, the calibration end wireless transmission device sends a start signal to the cooking appliance 100, which instructs the cooking appliance 100 to continue the power calibration process. Specifically, the calibration end wireless transmission device sends the start signal to the product end wireless transmission device 50.

[0101] After the start signal sent by the calibration device 200 is received by the product end wireless transmission device 50, the control device 40 controls the heating device 41 to work. After the heating device 41 works for a predetermined length of time (for example, 2 seconds), the heating power is stable, and the control device 40 obtains the working voltage value U and the working current value I of the heating device 41. Then, the control device 40 sends a second signal corresponding to the self-measured power value P2 of the cooking appliance 100 to the calibration end wireless transmission device 70 of the calibration device 200 through the product end wireless transmission device 50, where P2 = UI.

[0102] After the second signal sent by the cooking appliance 100 is received by the calibration device 200, the calibration end wireless transmission device 70 sends a fourth signal to the metering end wireless transmission device 80 of the power metering device 300, which is a handshake signal, so that the calibration device 200 and the power metering device 300 establish wireless communication.

[0103] After receiving the fourth signal sent by the calibration device 200, the power metering device 300 sends a metering signal corresponding to the actual power value PI of the cooking appliance 100 to the calibration device 200. Specifically, the metering end wireless transmission device 80 sends the metering signal to the calibration end wireless transmission device 70.

[0104] After receiving the metering signal, the calibration end wireless transmission device 70, the calibration module 60 reads information corresponding to the self-measured power value P2 and the actual power value PI from the calibration end wireless transmission device 70, and determines the power calibration parameter C according to the information. When the model of the cooking appliance is different, its rated power value is different. The calibration system according to the present application can set the rated power value of the cooking appliance according to its model, so that the calibration system according to the present application is suitable for cooking appliances of various models. Specifically, the user sets the rated power value PO of the cooking appliance 100 in advance through the setting module 61 of the calibration device 200, and the calibration module 60 determines the calibration parameter C according to the rated power value PO, the actual power value PI and the self-measured power value P2. The calibration parameter C = P2 + PI / P2 x (PO - PI). The calibration end wireless transmission device 70 sends a third signal corresponding to the power calibration parameter C to the product end wireless transmission device 50. Then the calibration device 200 ends the power calibration process.

[0105] After the product end wireless transmission device 50 receives the third signal, the control device 40 controls the heating device 41 to stop heating. Then the control device 40 reads the information corresponding to the power calibration parameter C from the product end wireless transmission device 50, and stores the power calibration parameter C to the storage device 42. The control device 40 ends the power calibration process.

[0106] After the cooking appliance 100 obtains the power calibration parameter C, during the cooking heating process, the control device 40 adjusts the PWM (Pulse Width Modulation) value to make the product of the working voltage and the working current of the heating device 41 as close to the C value as possible (for example, the difference between the product of the working voltage and the working current of the heating device 41 and the C value is controlled within ±C·5%), so that the cooking appliance 100 works at the rated power value.

[0107] The present application also provides a cooking system, which comprises the cooking appliance and the calibration system of the cooking appliance described above. As shown in the specific embodiment, the cooking system 500 according to the present application may, for example, comprise the cooking appliance 100 and the calibration system 400 of the cooking appliance. The cooking system 500 according to the present application can calibrate the working power of the cooking appliance 100 according to the working process described above. Figure 2

[0108] The cooking appliance, the calibration system of the cooking appliance and the cooking system according to the present application directly interact with the special calibration equipment through the WI-FI or Bluetooth module of the cooking appliance to quickly calibrate the whole machine. This method is fast and accurate, and can greatly reduce the labor intensity of workers. In addition, the whole machine calibration is more accurate than the calibration of the line board tooling alone, because the small differences in the structure parameters of the coil disc after the installation into the whole machine will cause the power deviation of the whole machine. The cooking appliance, the calibration system of the cooking appliance and the cooking system according to the present application improve the consistency of the cooking effect and improve the production efficiency of the product.
