The timing unit 511 can count down. The cooking system 100 of the present application includes the first wireless communication unit 40 of the cooking appliance and the timing device 50. The timing device 50 includes a timing control unit. The timing control unit includes a timing unit 511, a control unit 512, and a second wireless communication unit 513. The second wireless communication unit 513 and the timing unit 511 are respectively electrically connected to the control unit 512, and the second wireless communication unit 513 is communicatively connected to the first wireless communication unit 40. In this way, the main controller 30 can communicate with the timing device 50 through the first wireless communication unit 40 and the second wireless communication unit 513, so that signals can be transmitted between the main controller 30 and the timing device 50, and the main controller 30 can perform cooking control more flexibly and intelligently according to the signals of the timing device 50. In some embodiments, the control unit 512 obtains the timing duration of the timing unit 511. When the timing of the timing unit 511 ends, the control unit 512 can send an end instruction to the main controller 30 through the second wireless communication unit 513 and the first wireless communication unit 40.

[0046] Figure 3 The principle block diagram of an embodiment of the timing device 50 is shown. The timing device 50 includes a timing control unit 512. The timing control unit 512 includes a timing unit 511, a control unit 512, and a second wireless communication unit 513. The second wireless communication unit 513 and the timing unit 511 are respectively electrically connected to the control unit 512. The timing unit 511 is used for countdown. The user can set the required cooking duration according to usage habits, specifically by rotating a knob, key input, or wireless communication. When the countdown ends, the control unit 512 sends an end instruction to the first wireless communication unit 40 through the second wireless communication unit 513. The second wireless communication unit 513 is wirelessly connected to the first wireless communication unit 40, specifically through WIFI (wireless network communication technology), Bluetooth communication technology, infrared communication technology, or radio frequency communication technology, etc. When the first wireless communication unit 40 receives the end instruction from the second wireless communication unit 513, it passes the instruction to the main control 30, and the main control 30 controls the heater 20 to stop heating. Figure 1 The cooking system 100 is only an exemplary embodiment, and the present application is not limited to Figure 1 the shown cooking system 100 and can be other types of cooking systems 100.

[0047] The timing device 50 also includes a temperature sensor 52. The temperature sensor 52 extends into the cooking vessel assembly 10 and is used to obtain cooking temperature information. The temperature sensor 52 can be a thermistor, a thermocouple, a radiation temperature sensor, etc. The control unit 512 is electrically connected to the temperature sensor 52 and is used to obtain an electrical signal from the temperature sensor 52. The control unit 512 compares the temperature obtained by the temperature sensor 52 with the set temperature. When the temperature information obtained by the temperature sensor 52 is higher than the set temperature and is maintained for a set time, the control unit 512 sends a command to stop heating to the main control 30, and the main control 30 turns off the heater 20. If the temperature in the cooking vessel assembly 10 exceeds the set temperature, it means that the temperature is over-temperature and heating needs to be stopped. The user can set a cooking mode, such as steaming, boiling, stewing, braising, etc., and can send the cooking mode and start instruction to the main control 30 through the wireless communication unit, and the main control 30 controls the heater 20 according to the cooking mode.

The second heat insulation layer 532 is disposed between the first heat insulation layer 531 and the timing circuit assembly 51, and the thermal conductivity of the first heat insulation layer 531 is less than that of the second heat insulation layer 532. A large amount of heat from the cooking utensil assembly 10 can be isolated through the first heat insulation layer 531, and the second heat insulation layer 532 further protects the timing circuit assembly 51.

[0050] In some embodiments, the thickness of the first heat insulation layer 531 is greater than that of the second heat insulation layer 532 to improve the heat insulation effect of the heat insulation member 53.

[0051] In some embodiments, the first heat insulation layer 531 is a polypropylene heat insulation layer. Polypropylene has the characteristics of high temperature resistance and corrosion resistance. As the first heat insulation layer 531, it is not easily damaged due to contact with the high-temperature cooking utensil assembly, and can also protect the second heat insulation layer 532 and the timing circuit assembly 51 disposed thereon, which is beneficial to the service life of the timing device 50.

[0052] In some embodiments, the second heat insulation layer 532 is a mica layer. Mica has good mechanical strength and insulation properties, is easy to process, and when the timing circuit assembly 51 is disposed on the mica layer, it has better safety.

In some embodiments, when the timing unit 511 finishes timing, the control unit 512 controls the buzzer 514 to turn on and emit a sound to remind the user. In other embodiments, when the temperature information acquired by the temperature sensor 52 is higher than the set temperature and remains for a period of time, the control unit 512 controls the buzzer 514 to turn on. Through the buzzer 514, the user is reminded that the cooking is completed or an abnormality occurs during cooking, thereby reducing the risks of cooking failure and dry burning, which is beneficial to the use safety of the cooking system 100 and facilitates the use of the cooking system 100.

The display control module 515 at least includes a time area 5151, and the time area 5151 is used to display the duration. In some embodiments, the time area 5151 displays the remaining cooking duration in a countdown manner. In some embodiments, the user can also adjust the time required for the countdown of the timing device 50 by touching in the time area 5151; or by rotating the timing device 50 circumferentially; or by operating the buttons on the timing device 50.

As a specific implementation manner, the timing unit 511, the control unit 512, and the second wireless communication unit 513 are integrated on a system-on-chip (SoC). By the above method, the structural setting of the timing circuit assembly is simplified, and the operation of installing the timing circuit assembly 51 relative to the timing device 50 is simplified, facilitating the production of the timing device 50 and the cooking system 100.

[0058] In some embodiments, the power module 516 may also be integrated into the chip 55. The control unit 512 may read the remaining power in the power module 516.
