[0048] To facilitate the understanding of this embodiment, the embodiments of the present invention will be introduced in detail below.

[0049] Figure 1 And Figure 2 is a schematic structural diagram of the intelligent stir-frying control device provided in the first embodiment of the present invention.

[0050] Referring to Figure 1 And Figure 2 , the device includes: a wok 5, a pot lid 4, a controller 1, a temperature sensor 10, a motor 2 and a stirring system 11, and a lithium-ion rechargeable battery;

[0051] A temperature sensor 10 is provided at the bottom 9 of the wok 5, and a controller 1, a motor 2 and a stirring system 11 are provided on the pot lid 4. The motor 2 and the stirring system 11 can be detachably cleaned; a lithium-ion rechargeable battery and a lithium-ion rechargeable battery interface 7 are provided at the handle 6 of the wok 5; a connector 8 is provided between the wok 5 and the pot lid 4; it further includes a steam baffle 12 connected to the motor 2. The controller 1 controls the rotation angle of the motor 2 so that the motor 2 controls the steam baffle 12 to open or close the heat dissipation port 3 of the pot lid 4.

[0052] Embodiment two:

[0053] Figure 3 is a schematic diagram of the intelligent stir-frying control device provided in the second embodiment of the present invention.

[0054] Referring to Figure 3 , the device includes a lithium-ion rechargeable battery 13, a temperature sensor 10, a motor 2, a stirring system 11 and a controller 1; the lithium-ion rechargeable battery 13, the temperature sensor 10, the motor 2 and the stirring system 11 are respectively electrically connected to the controller 1;

[0055] A temperature sensor 10, configured to detect the bottom temperature of the wok when the gas stove is turned on, and obtain temperature information.

[0056] A controller 1, configured to receive recipe information sent by the range hood and temperature information sent by the temperature sensor 10 when the lid is closed on the wok and the lithium-ion rechargeable battery 13 provides electrical energy, and control the motor 2 and the stirring system 11 to operate according to the recipe information and the temperature information.

[0057] Specifically, the range hood includes, but is not limited to, specifically the ROKI (Robam Kitchen Intelligence, Robam's kitchen intelligent system) range hood and the range hood with Bluetooth linkage. The range hood has a Bluetooth function, and the controller 1 also has a Bluetooth function. After the user selects recipe information on the range hood, the range hood sends the locally stored recipe information to the controller 1 through the Bluetooth unit. Additionally, the range hood can also connect to the network, obtain recipe information from the network, and then send the recipe information on the network to the controller 1. Among them, the range hood and the gas stove also achieve information transmission and control through Bluetooth.

[0058] Place the wok on the gas stove, put the prepared ingredients, seasonings, and water in the wok, and cover the lid on the wok. At this time, the lithium-ion rechargeable battery 13 provides electrical energy for the controller 1, and the controller 1 starts to operate. Turn on the gas stove, the temperature sensor 10 detects the bottom temperature of the wok, obtains temperature information, and sends the temperature information to the controller 1. The controller 1 receives the recipe information sent by the range hood and controls the motor 2 and the stirring system 11 to operate according to the recipe information and the temperature information. Among them, the motor 2 includes, but is not limited to, specifically a stepper motor and a DC motor with a reduction gearbox. The range hood sends the recipe information to the gas stove through the Bluetooth unit, and the gas stove adjusts the firepower according to the recipe information. When the lid is opened, the motor 2 and the stirring system 11 stop operating, thus realizing the function of intelligent cooking.

[0059] Furthermore, a connector is provided between the wok and the lid, and the lithium-ion rechargeable battery 13 is electrically connected to the controller 1 through the power supply line inside the connector;

[0060] The lithium-ion rechargeable battery 13 is configured to provide electrical energy for the controller 1 when the lid is closed on the wok and the power supply line inside the connector is connected;

[0061] Or,

[0062] When the lid leaves the wok and the power supply line inside the connector is disconnected, it does not provide electrical energy for the controller 1.

[0063] Specifically, the connector can be a snap fastener, and a power supply line is provided inside the snap fastener. The lithium-ion rechargeable battery 13 is electrically connected to the controller 1 through the power supply line inside the connector. When the pot lid is closed on the wok, the power supply line inside the connector is connected, and at this time, the lithium-ion rechargeable battery 13 provides electrical energy to the controller 1; when the pot lid leaves the wok, the power supply line inside the connector is disconnected, and at this time, the lithium-ion rechargeable battery 13 cannot provide electrical energy to the controller 1, and the motor 2 and the stirring system 11 also stop working, thus avoiding the soup or the stirring system brought out when opening the pot lid from hurting the user and improving the safety of the user.

[0064] Since the intelligent stir-frying control device is used on a gas stove and does not allow wire harnesses to be exposed, using the lithium-ion rechargeable battery 13 can improve safety. After charging the intelligent stir-frying control device once, it can be used for 3 - 4 hours.

[0065] Further, referring to Figure 4 , the controller 1 includes a battery voltage detection unit 15 and an MCU (Microcontroller Unit) 14, and the battery voltage detection unit 15 is electrically connected to the MCU 14; referring to the structural schematic diagram of the battery voltage detection unit as shown in Figure 12 and the structural schematic diagram of the MCU as shown in Figure 5 , in Figure 12 , the interface VCC_DET of the battery voltage detection unit is connected to the MCU.

[0066] The battery voltage detection unit 15 is used to detect the current voltage of the lithium-ion rechargeable battery;

[0067] The MCU 14 is used to compare the current voltage with a preset voltage threshold. If the current voltage is less than the preset voltage threshold, a prompt message is generated. Among them, the power adapter supplies power to the lithium-ion rechargeable battery, and the specifications of the power adapter are: output voltage / current is 12.6VDC / 1A.

[0068] Further, the controller 1 further includes a display unit 16. Referring to the structural schematic diagram of the display unit as shown in Figure 6 , in Figure 6 , the interfaces DIN, CLK, and STB are respectively connected to the MCU. Among them, DIN receives the data signal of the MCU, CLK receives the clock signal of the MCU, and STB receives the chip select signal of the MCU.

[0069] The display unit 16 is electrically connected to the MCU 14 and is used to display the prompt message in a flashing form. The prompt message includes battery power information. Among them, the controller 1 further includes a button 21, and the button 21 is electrically connected to the MCU 14. Referring to Figure 11Schematic diagram of the key structure shown, where SW3 is the power button, SW2 is for controlling the manual rotation or stop of the motor; SW3 is for controlling the motor speed, which can be two speeds, 30 RPM or 45 PRM respectively, and D0 and D1 are connected to the MCU.

[0070] Specifically, the controller 1 includes a battery voltage detection unit 15. The battery voltage detection unit 15 detects the current voltage of the lithium-ion rechargeable battery in real time and sends the current voltage to the MCU 14; if the current voltage is less than the preset voltage threshold, the MCU 14 generates a prompt message and sends it to the display unit 16, and the display unit 16 displays the prompt message in a flashing form. Through the above voltage detection, it can remind the user to charge the intelligent stir-fry control device in real time, enabling the user to eat delicious meals in real time, meeting the user's usage requirements, and improving the user experience.

[0071] Furthermore, the device also includes a steam baffle connected to the motor 2, and the controller 1 also includes a motor drive unit 20. Refer to the Figure 7 Schematic diagram of the motor drive unit structure shown. When connected to the PWM (speed control) interface, the motor speed is controlled, and the speed is between 10 KHz - 30 KHz. When the MCU 14 inputs a high-level signal to the PWM interface, the motor stops. When a low-level signal is input, the motor starts to work. When connected to the F / R (forward / reverse) interface, when the MCU 14 inputs a high-level signal, the motor rotates forward; when the MCU 14 inputs a floating signal, the motor rotates in reverse; when connected to the FG (rotation speed signal), the motor sends a rotation speed signal to the MCU; when connected to the BR (brake), when the MCU 14 inputs a low-level signal, the motor brake is controlled.

[0072] The motor drive unit 20 is electrically connected to the MCU 14 and is used to control the rotation angle of the motor 2 according to the control instruction information sent by the MCU 14, so that the motor 2 controls the steam baffle to open or close the heat dissipation port of the pot lid.

[0073] Furthermore, the MCU 14 is used to determine the category and cooking parameters of the recipe according to the recipe information. If the category of the recipe is stewing, it sends a heat dissipation port closing instruction message to the motor drive unit 20; if the category of the recipe is stir-frying and the cooking parameters reach the preset conditions, it sends a heat dissipation port opening instruction message to the motor drive unit 20;

[0074] The motor drive unit 20 is used to control the motor 2 to rotate to the first angle according to the heat dissipation port closing instruction message, so that the motor 2 controls the steam baffle to close the heat dissipation port of the pot lid; or, controls the motor 2 to rotate to the second angle according to the heat dissipation port opening instruction message, so that the motor 2 controls the steam baffle to open the heat dissipation port of the pot lid;

[0075] Among them, the cooking parameters include cooking time and cooking temperature, and the preset conditions include that the cooking time reaches the preset time and / or the cooking temperature reaches the preset temperature.

[0076] Specifically, the motor 2 is connected to the steam baffle, and the motor 2 can control the steam baffle to open or close the heat dissipation port of the pot lid. Specifically: The MCU 14 judges the category of the recipe according to the recipe information, and can also determine the cooking time and cooking temperature corresponding to different cooking stages according to the recipe information. When the category of the recipe is stewed vegetables, the MCU 14 sends a heat dissipation port closing instruction message to the motor drive unit 20, and the motor drive unit 20 controls the motor to rotate to the first angle according to the heat dissipation port closing instruction message, so that the motor 2 controls the steam baffle to close the heat dissipation port of the pot lid; when the category of the recipe is stir-fried vegetables and the cooking parameters reach the preset conditions, the MCU 14 sends a heat dissipation port opening instruction message to the motor drive unit 20, and the motor drive unit 20 controls the motor 2 to rotate to the second angle according to the heat dissipation port opening instruction message, so that the motor 2 controls the steam baffle to open the heat dissipation port of the pot lid, avoiding a large amount of water vapor when opening the pot lid and scalding the user. The cooking parameters reaching the preset conditions can be that the stir-frying is about to end or high-fire thickening the sauce, which is specifically determined according to the set time and set temperature of different cooking stages in the recipe information.

[0077] Furthermore, the controller 1 further includes a Bluetooth unit 17. Referring to the Figure 8 structural schematic diagram of the Bluetooth unit shown, BT_TX, RXD, BT_RX, and TXD are connected to the MCU. Among them, when RXD receives the signal of the MCU, BT_TX is used to transmit the signal; when TXD sends the signal, BT_RX is used to receive the signal of the MCU.

[0078] The Bluetooth unit 17 is electrically connected to the MCU 14 and is used to receive the recipe information sent by the range hood and send the recipe information to the MCU 14.

[0079] Furthermore, the controller 1 further includes a power supply unit 18. Referring to the Figure 9 structural schematic diagram of the power supply unit shown, CN1 inputs electrical energy to U1 and U2. U1 converts the electrical energy into 5V voltage, and U2 converts the 5V voltage into 3.3V voltage. U1 mainly provides electrical energy for the MCU and the like, and U2 mainly provides electrical energy for the Bluetooth unit and the like.

[0080] The power supply unit 18 is electrically connected to the MCU 14 and is used to receive the electrical energy sent by the lithium-ion rechargeable battery 13 and send the electrical energy to the MCU 14.

[0081] Furthermore, the controller 1 further includes a temperature detection unit 19. Referring to the Figure 10 structural schematic diagram of the temperature detection unit shown, NTC is connected to the MCU, and CN2 is connected to the temperature sensor.

[0082] A temperature detection unit 19, electrically connected to the MCU 14, is configured to receive the temperature information sent by the temperature sensor 10 and send the temperature information to the MCU 14.

[0083] Specifically, the range hood sends the recipe information to the Bluetooth unit 17, and the Bluetooth unit 17 sends the recipe information to the MCU 14; when the temperature detection unit 19 detects the temperature at the bottom of the frying pan, it sends the temperature information to the MCU 14, and the MCU 14 controls the motor 2 and the stirring system 11 to work according to the recipe information and the temperature information.
