[0044] The embodiments provided by the present application will be specifically introduced below in combination with the accompanying drawings of the specification.

[0047] In some embodiments, the cooking device 1 includes at least one software module stored in the memory 3 in the form of software or firmware (Firmware) or solidified in the operating system (OS) of the cooking device 1.

[0048] In some embodiments, the controller 2 is used to execute the executable modules stored in the memory 3, for example, software function modules and computer programs included in the cooking device 1, to realize the control method of the cooking device.

[0049] In some embodiments, the controller 2 can execute the computer program after receiving the execution instruction. The controller 2 can be an integrated circuit chip with signal processing capability.

[0050] ​In some embodiments, the controller 2 can also be a general processor, for example, can be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a discrete gate or transistor logic, a discrete hardware component, can implement or execute the disclosed methods, steps and logic block diagrams in the embodiments of the present application, in addition, the general processor can be a microprocessor or any conventional processor, etc.

[0052] In some embodiments, the memory 3 is used to store a program, and the controller 2 executes the program after receiving an execution instruction.

[0053] Figure 2 A structural schematic block diagram of a cooking device is provided for the embodiments of the present application. As shown in the figure, the cooking device 1 comprises: a device body 11, a cooking cavity 12, a door body 13, and a human-computer interaction interface 14. Figure 1

[0054] In some embodiments, the device body 11 has a cooking cavity for accommodating cooking food materials.

[0055] In some embodiments, the cooking cavity 12 is used to accommodate cooking food materials.

[0056] In some embodiments, the human-computer interaction interface 14 is used for user to select cooking instructions and view cooking parameters.

[0057] Figure 3 A hardware structure block diagram of another cooking device is provided for the embodiments of the present application. As shown in the figure, the cooking device 1 further comprises: a humidity sensor 15 and a door body detection component 16. Figure 3

[0058] In some embodiments, the humidity sensor 15 is used to detect the humidity value of the cooking cavity. ​​

[0059] In some embodiments, the basic principle of the humidity sensor 15 is based on the fact that the thermal properties of humid air of different humidity levels are different at the same temperature. By balancing the temperature difference between the reference resistance and the resistance exposed to the environment, a difference in resistance value is caused, thereby forming a voltage difference. According to this voltage difference and the current temperature, the humidity value of the current humid air can be calculated.

[0060] It should be noted that, in the cooking environment, the humidity value and the temperature value are not in a fixed linear relationship. The humidity value at the same temperature value may be different, or the temperature value at the same humidity value may be different. Figure 4 A temperature and humidity corresponding curve diagram provided for the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the humidity values detected by the humidity sensor 15 at different temperatures of the cooking cavity may be the same. Figure 4

[0061] In some embodiments, the humidity sensor 15 is also applicable to scenarios with a temperature of 100°C or higher.

[0062] In some embodiments, it is found through testing that, in the complete cooking program of the cooking device, the humidity sensor 15 may appear two curves, Figure 5 A humidity value trend broken line diagram provided for the embodiments of the present application is shown in FIG. 2. As shown in FIG. 2, the humidity value first decreases, then increases, and finally stabilizes, Figure 5 A humidity value trend broken line diagram provided for another embodiment of the present application is shown in FIG. 3. As shown in FIG. 3, the humidity value decreases all the time until it stabilizes. Figure 5 Figure 6 According to these characteristics, when the cooking device runs the cooking program, the controller controls according to the data detected by the humidity sensor 15. The control method needs to be able to judge both curve characteristics at the same time, and determine the cooking process according to the curve characteristics.

[0063] In some embodiments, the reading of the humidity sensor 15 is the voltage value of the humidity sensor 15.

[0064] In some embodiments, the door body detection assembly 16 is used to detect the opening and closing state of the door body 13.

[0065] In some embodiments, the door body detection assembly 16 can sense the opening or closing state of the door body 13, and when the change state appears and lasts for a short time (such as 0.1s), it will report the feedback of the current state to the controller.

[0066] In some embodiments, the door body detection assembly 16 can sense the opening or closing state of the door body 13, and when the change state appears and lasts for a short time (such as 0.1s), it will report the feedback of the current state to the controller.

[0067] ​​In the embodiments shown in the present application, the controller 2 refers to a device that can generate operation control signals according to instruction operation codes and timing signals to instruct the cooking device 1 to execute control instructions. Exemplarily, the controller 2 can be a central processing unit (CPU), a general processor network processor (NP), a digital signal processing (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller 2 can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not make any limitation thereto.

[0068] In addition, the controller 2 can be used to control various components inside the cooking device 1 to enable the components to operate to achieve various predetermined functions of the cooking device 1.

[0069] Figure 7 A hardware configuration block diagram of the cooking device 1 provided by the embodiments of the present application is shown in the figure. Figure 7 As shown in the figure, the cooking device 1 can further include a communication interface 1001.

[0070] In some embodiments, the communication interface 1001 is used to establish a communication connection with other network entities, such as a terminal device. The communication interface 1001 can include a radio frequency (RF) module, a cellular module, a wireless fidelity (WIFI) module, and a GPS module, etc. Taking the RF module as an example, the RF module can be used for receiving and transmitting signals, in particular, transmitting the received information to the controller 2 for processing; in addition, transmitting the signals generated by the controller 2. Generally, the RF circuit can include but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc.

[0071] Those skilled in the art can understand that Figure 7 The hardware structure shown in the figure does not constitute a limitation on the cooking device 1, and the cooking device 1 can include more or fewer components than shown in the figure, or combine certain components, or different component arrangements.

[0072] Figure 8 An internal interaction schematic diagram of a cooking device provided by the embodiments of the present application is shown in the figure. Figure 8 As shown in the figure, the cooking device 1 can further include a heating system 17 and a temperature sensor 18.

[0073] In some embodiments, the heating system 17 can be an infrared heating tube, a resistance heating tube, a graphene heating tube, or a carbon fiber heating tube, etc. The type of the heating system of the cooking system is not limited in the present application.

[0074] In some embodiments, the heating system 17 can be arranged above, below, or opposite to the cooking cavity 12. When the controller 2 starts the heating system 17, the heating system 17 starts to heat the cooking cavity 12. The heating system 17 can also be equipped with a fan (not shown) to enhance the convective heat exchange. Figure 8

[0075] In some embodiments, the temperature sensor 18 is installed inside the cooking cavity to detect the temperature rise of the air in the cooking cavity and feed back the temperature value per second.

[0076] In some embodiments, the humidity sensor 15 is installed close to the temperature sensor 18 to ensure that the temperature value at the position of the humidity sensor 15 is close to the temperature value read by the temperature sensor 18.

[0077] In some embodiments, the user can view the cooking parameters or select the menu through the human-computer interaction interface 14.

[0078] Figure 9 A control method flow chart of a cooking device provided by the embodiments of the present application is shown in FIG. 10. The method comprises the following steps: Figure 9

[0079] S101, when the cooking device runs a cooking program, the controller acquires the humidity value data of the cooking cavity.

[0080] In some embodiments, in response to the cooking instruction input by the user, the controller controls the cooking device to run the cooking program indicated by the cooking instruction.

[0081] In some embodiments, the controller can periodically acquire the humidity value data of the cooking cavity through the humidity sensor at a first preset time length.

[0082] The cooking instruction is pre-stored in the memory of the cooking device. The cooking program is a group of cooking programs that can include a set temperature, a preheating time, a first stage time, and a second stage time.

[0083] When the user cooks food using the cooking device, the corresponding food category can be input through the human-computer interaction interface of the cooking device, i.e., the cooking instruction is input.

[0084] For example, the user inputs the instruction to bake a pizza. The input can be through voice input, selection of a food category button, or automatic recognition (such as image recognition, etc.) of the cooking device.

[0085] ​​It should be noted that the cooking food suitable for the cooking equipment provided in the present application is a mixed food of ingredients, that is, the food includes at least two categories of ingredients, for example, possible mixed ingredients such as vegetables and pasta, meat and pasta, pasta and vegetables, and meat.

[0086] For example, the cooking food includes at least two categories of ingredients, and the degrees of cooking of the at least two categories of ingredients are different. For example, the pasta in the cooked food is required to be baked dry, while the vegetables and meat are required to ensure a certain moisture content. That is, in the cooking process, the moisture of one category of ingredients is required to escape more than the moisture of another category of ingredients.

[0087] In some embodiments, one category of ingredients in the cooking food is pasta, and another category of ingredients is at least one of vegetables, meat, and dairy products. For example, a pizza includes a pizza crust and vegetables and meat placed on the pizza crust, which is a mixed food of ingredients.

[0088] Optionally, the pre-stored cooking instructions in the cooking equipment can include cooking programs corresponding to other possible mixed dishes such as baking a pizza or baking a hot dog.

[0089] Further, the controller can control the cooking equipment to run the cooking program corresponding to the cooking instruction input by the user according to the preset correspondence.

[0090] The preset correspondence is used to indicate at least one cooking instruction and at least one group of cooking programs.

[0091] For example, the preset correspondence can be implemented in the form of a correspondence table. Table 1 shows a correspondence table. As shown in Table 1, the preset correspondence can include a plurality of cooking instructions and a plurality of groups of cooking programs, and there is a one-to-one correspondence between at least one cooking instruction and at least one group of cooking programs.

[0092] Table 1

[0093]

[0094] For example, when the user inputs the cooking instruction of "baking a pizza", the controller controls the cooking equipment to run the cooking program corresponding to the cooking instruction, which is: setting the temperature a ℃ , preheating time A min , first stage time d min , and second stage time g min .

[0095] For example, when the user inputs the cooking instruction of "baking a hot dog", the controller controls the cooking equipment to run the cooking program corresponding to the cooking instruction, which is: setting the temperature b ℃ , preheating time B minthe first stage time e min and the second stage time h min .

[0096] For example, when the user inputs the cooking instruction "roast dessert", the controller controls the cooking device to run the cooking program corresponding to the cooking instruction, which is: setting the temperature c ℃ , the preheating time C min , the first stage time f min , and the second stage time i min .

[0097] It should be understood that the cooking instructions provided by the embodiments of the present application include but are not limited to the cooking instructions shown in Table 1, which are not limited by the present application.

[0098] In some embodiments, before controlling the cooking device to run the cooking program corresponding to the cooking instruction, a preheating program corresponding to the cooking instruction is controlled to run, and the temperature value in the cooking cavity is periodically acquired by the temperature sensor for a second preset time period, and the temperature sensor is initialized according to the temperature value and a preset temperature threshold.

[0099] Optionally, the second preset time period can be 1 second, and the preset temperature threshold is the working temperature range (a℃-b℃) of the temperature sensor.

[0100] For example, when the cooking device runs the cooking program corresponding to the cooking instruction, the cooking device enters the preheating program and starts heating, and the temperature in the cooking cavity of the device starts to rise. At this time, the temperature sensor starts to detect the temperature value in the cooking cavity every second. When the temperature value in the cooking cavity every second is between (a℃-b℃), the initialization of the temperature sensor ends.

[0101] Further, the temperature in the cooking cavity is continuously acquired by the temperature sensor, and when the temperature in the cooking cavity is less than the preset temperature, the controller controls the cooking device to continue running the preheating program. When the temperature in the cooking cavity reaches the preset temperature, the controller controls the cooking device to end the preheating program.

[0102] In some embodiments, during the running of the cooking program by the cooking device, the heating assembly of the cooking device is intermittently turned on or interrupted according to a preset temperature control method, so as to ensure that the temperature detected by the temperature sensor is consistent with the set temperature.

[0103] In some embodiments, before controlling the cooking device to run the cooking program corresponding to the cooking instruction, the opening and closing state of the door body is detected by the door body detection assembly. When it is detected that the closing state of the door body meets a preset condition, the cooking device is controlled to run the cooking program corresponding to the cooking instruction.

[0104] The preset condition includes that the door body changes from an open state to a closed state.

[0105] In some embodiments, the first preset time length and the second preset time length can be one second, etc. The time length of one cycle can be half a minute, one minute, etc. The present application does not limit this.

[0106] Optionally, the humidity value data comprises a humidity value average of the cooking device in the second cycle, a humidity value average of the cooking device in the first cycle, a humidity value average of the cooking device in the current cycle, a difference between the humidity value average of the cooking device in the second cycle and the humidity value average of the cooking device in the first cycle, and a difference between the humidity value average of the cooking device in the first cycle and the humidity value average of the cooking device in the current cycle.

[0107] S102, the controller determines a first humidity value change amount and a second humidity value change amount according to the humidity value data of the cooking cavity.

[0108] The first humidity value change amount is a change amount between the humidity value data of the current cycle and the first cycle, and the second humidity value change amount is a change amount between the humidity value data of the first cycle and the second cycle. The first cycle is a previous cycle of the current cycle, and the second cycle is a previous cycle of the first cycle.

[0109] In some embodiments, the humidity value data of the current cycle comprises an average of a plurality of humidity values detected by the cooking device in the current cycle periodically with a first preset time length, the humidity value data of the first cycle comprises an average of a plurality of humidity values detected by the cooking device in the first cycle periodically with the first preset time length, and the humidity value data of the second cycle comprises an average of a plurality of humidity values detected by the cooking device in the first cycle periodically with the first preset time length.

[0110] For example, when the first preset time length is one second and the time length of one cycle is one minute, the cooking device detects 60 humidity values in one minute. According to the 60 humidity values, the average of the humidity values of the current cycle is calculated.

[0111] For example, when the first preset time length is two seconds and the time length of one cycle is one minute, the cooking device detects 30 humidity values in one minute. According to the 30 humidity values, the average of the humidity values of the first cycle is calculated.

[0112] In some embodiments, the first humidity value change amount is a difference between the average of a plurality of humidity values detected by the cooking device in the current cycle periodically with the first preset time length and the average of a plurality of humidity values detected by the cooking device in the first cycle periodically with the first preset time length.

[0113] In some embodiments, the second humidity value change amount is a difference between an average of the plurality of humidity values detected in the first preset time period in the first cycle and an average of the plurality of humidity values detected in the first preset time period in the second cycle.

[0114] S103, in a case where the difference between the first humidity value change amount and the second humidity value change amount is within a preset difference value range, the controller controls the cooking device to end the cooking program.

[0115] In some embodiments, the preset difference value range can be (Δ1, Δ2).

[0116] In some embodiments, when the cooked time length of the cooking device is less than the total time length of the above three cycles, the controller determines that the cooking device is currently still in the device heating stage, at which time, the calculation of the difference between the average values of the humidity values in each cycle is not required. When the cooked time length of the cooking device is greater than or equal to the total time length of the above three cycles, the controller starts to calculate the difference between the average values of the humidity values in each cycle.

[0117] In a specific implementation, the cooked time length can be represented by t0, the total time length of the three cycles is represented by t s , and the difference (y0-y1) between the average value y1 of the plurality of humidity values detected in the first preset time period in the current cycle and the average value y0 of the plurality of humidity values detected in the first preset time period in the first cycle is represented by β.

[0118] For example, when t0 s , the cooking device is still in the device heating stage, and continues to heat until t0=t s . When t0≥t s , and Δ1<β<Δ2, the controller determines that the cooking device is in the first cooking stage of the cooking program, at which time, the controller sets the ripeness flag of the cooking food in the cooking cavity to 0.

[0119] On the contrary, when t0≥t s , and β<Δ1 or β>Δ2, the controller controls the cooking device to continue to run the cooking program, at which time, the food in the cooking cavity is not ripe, and the controller sets the ripeness flag of the cooking food in the cooking cavity to 1.

[0120] Further, when the ripeness flag of the cooking food in the cooking cavity is 1, the average value y0 of the plurality of humidity values detected in the first preset time period in the first cycle is set to y ’ , if in the next N cycles, β<Δ1 or β>Δ2, the controller controls the cooking device to end the first cooking stage of the cooking program and enter the second cooking stage of the cooking program.

[0121] Figure 10 Another flowchart of a control method of a cooking device provided by an embodiment of the present application is shown in FIG. 6. As shown in FIG. 6, the method further includes the following steps: Figure 10

[0122] In some embodiments, when the difference between the first humidity value change amount and the second humidity value change amount is not within the preset difference value range, the controller controls the cooking device to continue running the cooking program.

[0123] For example, when t0≥t s , and Δ1<β<Δ2, the controller controls the cooking device to continue running the cooking program.

[0124] In some embodiments, when the cooking device starts running the cooking program, the controller controls the human-computer interaction interface to display "Intelligent detection in progress...". When the controller detects that the difference in the cooking device is less than or equal to the difference threshold, the controller controls the human-computer interaction interface to display "Intelligent detection of food is ripe, end of cooking".

[0125] It should be understood that the prompts of the human-computer interaction interface described above can be other sentences with similar meanings, which are not limited in the present application.

[0126] The technical solutions provided by the embodiments of the present application at least bring the following beneficial effects: the humidity sensor can monitor the humidity value in the cooking cavity in real time, and the cooking device can run different cooking programs according to the user's needs, and according to the relationship between the difference between the first humidity value change amount and the second humidity value change amount of the current period and the preset difference value range, whether to end the current cooking program is determined, so as to avoid the controller running the judgment algorithm in real time, reduce the occupation of computing resources, and at the same time, through comparison with the preset difference value range, different ripening curves can be distinguished, so that the ripeness of the current food is determined by the humidity value in the cooking cavity, and the cooking program is ended in time after the ripeness of the food reaches the expected target to avoid the problem of overcooking, thereby achieving a better cooking effect.

[0127] In some embodiments, when the cumulative cooking time of the cooking program exceeds the preset cooking time, the controller controls the cooking device to end running the cooking program.

[0128] The preset cooking time is obtained by measurement and is pre-stored in the memory of the cooking device,

[0129] In a specific implementation, the cumulative cooking time of the cooking program is represented by t a The preset cooking time is represented by t1.

[0130] It should be noted that the preset cooking time t1 is set to limit the maximum cooking time of the cooking program, which is used to automatically end the current cooking program and avoid overcooking.​

[0131] For example, when t a ≥ t1, the controller controls the cooking device to end running the cooking program. In some embodiments, a second cooking stage can also be run after the cooking program ends running. The preset cooking time of the second cooking stage is t2.

[0132] For example, when the cooking time of the second cooking stage reaches (t2 / t1)*t a , the controller controls the cooking device to end the second cooking stage.

[0133] Optionally, t2 can be 0, that is, the cooking program ends running without entering the second cooking stage.

[0134] In some embodiments, the detection of the opening and closing state of the door body can also be achieved by the method as shown in Figure 11 , which includes the following steps: Figure 11 Another flowchart of a control method of a cooking device provided by the embodiments of the present application is shown in Figure 11 , which is used to determine the opening and closing state of the door body. The method includes the following steps:

[0135] S201. Before the cooking device runs the cooking program, the controller acquires the opening and closing state of the door body.

[0136] In some embodiments, the controller can detect the opening and closing state of the door body through the door body detection assembly.

[0137] S202. When it is detected that the closing state of the door body meets the preset condition, the controller controls the cooking device to run the cooking program.

[0138] The preset condition includes that the door body changes from the opening state to the closing state.

[0139] In some embodiments, in order to avoid accidents caused by the cooking device cooking when the door body is not in the closing state, when the closing state of the door body changes from the opening state to the closing state, the controller controls the cooking device to run the cooking program corresponding to the cooking instruction, thereby improving the cooking safety.

[0140] In some embodiments, the initialization of the temperature sensor can also be achieved by the method as shown in Figure 12 , which includes the following steps: Figure 12 Another flowchart of a control method of a cooking device provided by the embodiments of the present application is shown in Figure 12 , which is used to initialize the temperature sensor. The method includes the following steps:

[0141] S301. Before the cooking device runs the cooking program, the controller controls the cooking device to run a preheating program.

[0142] It should be noted that after the user selects the recipe, before the cooking device runs the cooking program of the recipe, the cooking device needs to start a preheating program to preheat the cooking cavity, so as to better cook the cooking materials.

[0143] S302, the controller acquires the temperature value in the cooking cavity.

[0144] In some embodiments, the controller can periodically acquire the temperature value in the cooking cavity through the temperature sensor for a second preset time length.

[0145] Optionally, the second preset time length can be 1 second.

[0146] For example, after the cooking device runs the cooking program corresponding to the cooking instruction, the cooking device enters the preheating program and starts heating, and the temperature in the cooking cavity of the device starts to rise. At this time, the temperature sensor starts to detect the temperature value in the cooking cavity every second.

[0147] S303, the controller initializes the temperature sensor according to the temperature value and the preset temperature threshold.

[0148] In some embodiments, when the temperature value in the cooking cavity acquired by the controller is between (a℃-b℃), the initialization of the temperature sensor ends.

[0149] Further, the temperature in the cooking cavity is continuously acquired through the temperature sensor, and when the temperature in the cooking cavity is less than the preset temperature, the controller controls the cooking device to continue running the preheating program. When the temperature in the cooking cavity reaches the preset temperature, the controller controls the cooking device to end the preheating program.

[0150] In some embodiments, the above steps S101-S103 can also be implemented by the method as shown in Figure 13 , Figure 13 Another flowchart of a control method of a cooking device provided by the embodiments of the present application is shown in Figure 13 , and the method comprises the following steps:

[0151] S11, the user selects a recipe.

[0152] In some embodiments, after the user selects the recipe, the human-computer interaction panel issues the set temperature T0, the set first stage time length t1 and the set second stage time length t2 indicated by the recipe.

[0153] S12, the heating system starts.

[0154] In some embodiments, after the recipe is determined, the heating system starts to heat the cooking cavity and starts the preheating program to preheat the cooking cavity.

[0155] S13, the temperature value T in the cooking cavity is acquired.

[0156] In some embodiments, the temperature value T in the cooking cavity can be acquired by a temperature sensor.

[0157] S14, if T≥T0, the preheating procedure ends, and the first cooking stage is entered; if T

[0158] S15, the humidity value data in the cooking cavity is acquired.

[0159] In some embodiments, the humidity value data includes the humidity value average of the cooking device in the last period, the humidity value average of the cooking device in the current period, the humidity value average of the cooking device in the next period, the difference between the humidity value average of the cooking device in the current period and the humidity value average of the cooking device in the last period, and the difference between the humidity value average of the cooking device in the next period and the humidity value average of the cooking device in the current period.

[0160] S16, if the difference between the first humidity value change amount and the second humidity value change amount is within the preset difference range, the step S15 is executed; otherwise, the ripeness flag is marked as 1, and y ’ =y0.

[0161] S17, if the difference between the first humidity value change amount and the second humidity value change amount is within the preset difference range for N periods, in the case that the difference between the first humidity value change amount and the second humidity value change amount is not within the preset difference range, the step S16 is executed; in the case that the difference between the first humidity value change amount and the second humidity value change amount is within the preset difference range, the step S15 is executed; otherwise, the first cooking stage duration is recorded, and the second cooking stage is entered.

[0162] S18, in the case that the second cooking stage duration≥(t2 / t1)*t a , the cooking procedure ends; otherwise, the step S17 is executed.
