The type of the material is determined according to the electrical parameters detected by the detection circuit, the corresponding cooking program is determined according to the type, and the cooking device is controlled to operate according to the cooking program, thereby improving the user experience.

[0013] The detection circuit is used to detect the electrical parameters of the material, and the type of the material is identified according to the electrical parameters. No additional structure needs to be arranged on the material, and the cooking device does not need to have the capabilities of NFC communication and image processing. Therefore, the structure is simple, the cost is low, and the processing resources required are few. Specifically, different types of materials, such as meat, rice, fruits and vegetables, have different electrical parameters, including resistance, capacitance or inductance. Therefore, after the electrical parameters of the material placed in the cooking cavity are determined, the type of the material can be determined. That is, when the material is placed in the cooking cavity, the material will contact the detection circuit. At this time, the detection circuit can detect the electrical parameters of the material and send the detected electrical parameters to the controller.

The obtained cooking program corresponds to the type of the material. The cooking device is controlled to work through the cooking program, so that the cooking cavity can be cooked according to the type of the material. Therefore, the cooking device can automatically identify the type of the material and automatically specify the corresponding cooking process, thereby improving the automation and intelligence of the cooking device.

Specifically, the detection circuit includes an input end, the input end is used for receiving a voltage signal, which can supply power to the detection circuit on one hand, and is also a comparison signal for detecting the resistance of the material on the other hand. The first resistor is specifically a signal resistor of the detection circuit, and the second resistor is specifically a grounding resistor. When the material is placed in the cooking cavity, the equivalent resistance of the material will form a parallel connection with the first resistor, and the first resistor and the second resistor are in series connection. Therefore, the voltage signal input by the input end will be divided by the first resistor, the second resistor and the equivalent resistance of the material. At this time, by detecting the voltage information at both ends of the first resistor, the equivalent resistance of the material can be calculated, that is, the electric parameter of the material is obtained.

[0019] By detecting the resistance value of the material, the type of the material is determined, the cooking program is determined according to the type of the material, and the cooking device is controlled to work through the cooking program. The food in the cooking cavity can be cooked in a targeted manner, so that the cooking device can automatically identify the type of food and automatically specify a targeted cooking process, thereby improving the automation and intelligence of the cooking device.

[0020] In any of the above technical solutions, the detection circuit further includes: a first detection member connected with the first end of the first resistor; and a second detection member connected with the second end of the first resistor.

[0021] In the technical solution, the first detection member and the second detection member are located in the cooking cavity. When the material is placed in the cooking cavity, the material can simultaneously contact the first detection member and the second detection member. Specifically, the first detection member and the second detection member can be a probe, an electrode or a metal sheet. When the material enters the cooking cavity and contacts the first detection member and the second detection member, an electric circuit is formed among the first detection member, the second detection member and the material, so as to determine the resistance value of the material by injecting current into the material or applying voltage to the material, and determine the corresponding cooking program according to the resistance value, thereby realizing automatic intelligent cooking.

[0022] In any of the above technical solutions, the electrical parameter includes a capacitance value, the controller includes a second detection terminal and a signal output terminal, the signal output terminal is configured to output a pulse width modulation (PWM) signal, the detection circuit includes: a first capacitor connected to the signal output terminal; a third resistor, a first end of the third resistor being connected to the first capacitor, and a second end of the third resistor being connected to the second detection terminal; and a fourth resistor, a first end of the fourth resistor being connected to the second end of the third resistor, and a second end of the fourth resistor being grounded.

[0023] In this technical solution, the electrical parameter can include a capacitance value, that is, the detection circuit detects the capacitance value of the material in the cooking cavity, determines the type of the material according to the capacitance value, and determines the corresponding cooking program.

[0024] Specifically, the controller includes a signal output terminal capable of outputting a PWM (pulse width modulation) signal, the first capacitor is a PWM signal output capacitor, the third resistor is connected in series with the first capacitor to form a signal output path, and the fourth resistor is connected in series with the signal output path. When the material is placed in the cooking cavity, the equivalent capacitance of the material is equivalent to being connected in parallel with the fourth resistor.

[0025] In this technical solution, the voltage across the fourth resistor is related to the equivalent capacitance of the material during a period of time when the PWM signal is output. Therefore, by collecting the voltage across the fourth resistor when the PWM signal is output, the equivalent capacitance of the material can be determined, that is, the electrical parameter of the material is obtained. By detecting the capacitance value of the material, the type of the material is determined, and the cooking program is determined according to the type of the material. The cooking device is controlled to work through the cooking program, which can be used to cook the food material in the cooking cavity in a targeted manner. Therefore, the cooking device can automatically identify the type of the food material and automatically specify a targeted cooking process, thereby improving the automation and intelligence of the cooking device.

[0026] In any of the above technical solutions, the detection circuit further includes: a third detection member connected to the first end of the fourth resistor; and a fourth detection member connected to the second end of the fourth resistor.

[0027] In this technical solution, the third detection member and the fourth detection member are located in the cooking cavity, and when the material is placed in the cooking cavity, the material can simultaneously contact the third detection member and the fourth detection member. Specifically, the third detection member and the fourth detection member can be a probe, an electrode, or a metal sheet. When the material enters the cooking cavity and contacts the third detection member and the fourth detection member, an electrical circuit is formed among the third detection member, the fourth detection member, and the material. Therefore, the resistance value of the material is determined by injecting a current into the material or applying a voltage to the material, and the corresponding cooking program is determined according to the resistance value, thereby realizing automatic intelligent cooking.

[0028] According to a second aspect of the present application, a control method of a cooking device is provided, which is used in any of the above technical solutions, and the method comprises: collecting an electrical parameter in the cooking cavity; and determining a material category in the cooking cavity according to the electrical parameter.

[0029] In this technical solution, a detection circuit is arranged in the cooking cavity, and the material is placed in the cooking cavity and contacts the detection circuit, and the contact mode can be a contact mode such as a probe, an electrode, a metal sheet, and the like. The electrical parameter of the material is collected by the detection circuit.

[0030] After the electrical parameter of the material is obtained, the category of the material is determined according to the electrical parameter of the material, and a corresponding program is determined according to the category of the material. The obtained cooking program corresponds to the material category, and the cooking device is controlled to work through the cooking program. The cooking device can be used to cook the material in the cooking cavity, so that the cooking device can automatically identify the material category and automatically specify the corresponding cooking process, thereby improving the automation and intelligence of the cooking device.

[0032] In this technical solution, the collected electrical parameter can be a resistance value. The detection circuit in the cooking device is provided with a second resistance. The first voltage value of the second resistance in the detection circuit is collected by the controller to determine the resistance value of the material.

[0033] Specifically, the detection circuit includes an input end, which is used to receive a voltage signal. The voltage signal can be used to supply power to the detection circuit, and is also used as a comparison signal for detecting the resistance of the material. The first resistance is specifically a signal resistance of the detection circuit, and the second resistance is specifically a grounding resistance. When the material is placed in the cooking cavity, the equivalent resistance of the material will form a parallel connection with the first resistance, and the first resistance and the second resistance are connected in series. Therefore, the voltage signal input into the input end will be divided by the first resistance, the second resistance, and the equivalent resistance of the material. At this time, the equivalent resistance of the material can be calculated by detecting the voltage information at both ends of the first resistance, that is, the electrical parameter of the material is obtained.

[0034] In any of the above technical solutions, the cooking device further includes a controller and a fourth resistance, and the electrical parameter includes a capacitance value; the electrical parameter in the cooking cavity is collected, including: controlling the controller to output a pulse width modulation signal to the cooking cavity; collecting a second voltage value on the fourth resistance; and determining the capacitance value according to the second voltage value.

The controller is provided with a signal output end for outputting a pulse width modulation signal. Specifically, the controller outputs a pulse width modulation signal to the detection circuit, and the detection circuit collects a second voltage value across the fourth resistor after receiving the pulse width modulation signal. The second voltage value across the fourth resistor is related to the capacitance value of the material within a certain time, and thus the capacitance value of the material can be derived according to the second voltage value across the fourth resistor. The controller determines the category of the material according to the capacitance value of the material.

[0036] In any of the above technical solutions, the category of the material in the cooking cavity is determined according to the electric parameter, including: obtaining a preset category set, wherein the preset category set includes a plurality of preset categories, each of which is associated with a first electric parameter range; determining the category of the material in the preset category set based on the correspondence between the electric parameter and the first electric parameter range.

[0037] In the technical solution, the controller is pre-set with a plurality of cooking programs, wherein different cooking programs are applicable to different materials to be cooked, and a plurality of electric parameters corresponding to a plurality of materials are stored. It can be understood that the plurality of materials and the plurality of electric parameters correspond one by one. In work, the controller can find the corresponding material category in the preset set according to the collected electric parameter.

[0038] Specifically, after the detection circuit detects the electric parameter of the material in the cooking cavity, the electric parameter is transmitted to the controller. After the controller collects the electric parameter, the preset set is called, the first electric parameter range matching the electric parameter is determined in the plurality of electric parameter ranges in the preset set according to the electric parameter, and the category of the material actually placed in the current cooking cavity is judged according to the material category corresponding to the first electric parameter range, so as to realize the function of determining the category of the material according to the electric parameter of the material.

[0039] In any of the above technical solutions, the category of the material in the cooking cavity is determined according to the electric parameter, and further includes: determining that there is no material in the cooking cavity based on the condition that the electric parameter satisfies a second electric parameter range.

[0040] In the technical solution, if the electric parameter of the material is detected to be in the second electric parameter range. The second electric parameter range can be an electric parameter that cannot be detected, i.e. the electric parameter is empty.

[0041] The application sets a detection circuit to detect the electric parameter of the material in the cooking cavity, which can determine the specific type of the material according to the electric parameter, so as to cook the material through the cooking program matched with the material type, and realize the intelligent and automatic cooking process. On the other hand, the detection circuit can also detect whether there is material in the cooking cavity according to the reading, that is, to judge the internal state, and without setting structures such as weight sensor and image sensor, the low-cost material detection is realized, which is beneficial to realize the low-cost automatic cooking.

[0042] In any of the above technical solutions, the control method of the cooking device further comprises: determining a corresponding cooking program according to the material category, and controlling the cooking device to operate through the cooking program.

[0043] In this technical solution, the cooking device further comprises determining a corresponding cooking program according to the category of the material, and the controller sends the cooking program to the corresponding cooking device, and then controls the cooking device to operate. Specifically, different types of materials have different cooking methods. For example, meat can be stir-fried, rice can be steamed, etc. Therefore, different cooking programs for different categories of materials are set in the controller. Among them, the controller determines the category of the material through the electric parameter, and then calls different cooking programs in the controller according to the category of the material, which can cook the food in the cooking cavity in a targeted manner, so that the cooking device can automatically identify the type of food and automatically specify the targeted cooking process, thereby realizing the intelligence and automation of the cooking device, and improving the use experience of the cooking device.

[0064] The following reference Figures 1 to 9 This invention describes a cooking apparatus and its control method and control device, as well as a readable storage medium, according to some embodiments of the present invention.

[0065] Example 1

Figure 1 As shown, the cooking device includes: a main body, including a cooking cavity; a detection circuit 200, disposed in the cooking cavity, for detecting the electrical parameters of the material 300 in the cooking cavity; and a controller 100, disposed in the main body and connected to the detection circuit 200, for determining the type of material 300 based on the electrical parameters, determining the corresponding cooking program based on the type, and controlling the operation of the cooking device according to the cooking program.

[0067] The cooking equipment provided by the application comprises a body, the body is used for accommodating main components of the cooking equipment, so as to avoid that the components are exposed to air, thereby avoiding that water or impurities in the air cause corrosion or damage to the components of the cooking equipment, and the service life of the cooking equipment is ensured. The body comprises a cooking cavity, the cooking cavity is used for containing materials 300, so that the materials 300 can be cooked in the cooking cavity.

[0068] The cooking equipment further comprises a detection circuit 200 arranged in the cooking cavity, when the materials 300 are placed in the cooking cavity, the materials will contact the detection circuit 200 after entering the cooking cavity, so that the electrical parameters of the materials 300 in the cooking cavity are accurately detected and identified. The cooking equipment further comprises a controller 100 used for controlling the whole cooking equipment. The controller 100 is arranged in the body and connected with the detection circuit 200. The type of the materials 300 is determined according to the electrical parameters detected by the detection circuit 200, the corresponding cooking program is determined according to the type, and the cooking equipment is controlled to operate according to the cooking program, thereby improving the use experience of the user.

[0069] The application detects the electrical parameters of the materials 300 by using the detection circuit 200, the type of the materials is identified by using the electrical parameters, no additional structure needs to be arranged on the materials, and the cooking equipment does not need to have the capabilities of NFC communication and image processing, so that the structure is simple, the cost is low, and the required processing resources are few.

[0070] Specifically, different types of materials, such as meat, rice and fruits and vegetables, have different electrical parameters, including resistance, capacitance or inductance, etc. Therefore, after the electrical parameters of the materials placed in the cooking cavity are determined, the type of the materials can be known. That is to say, when the materials are placed in the cooking cavity, the materials will contact the detection circuit, at this time, the detection circuit can detect the electrical parameters of the materials and send the detected electrical parameters to the controller.

[0071] After the controller 100 receives the electrical parameters detected by the detection circuit 200, the type of the materials 300 is determined by looking up a table according to the received electrical parameters, and the corresponding cooking program is determined according to the type of the materials, wherein the obtained cooking program corresponds to the type of the materials, the cooking equipment is controlled to work by using the cooking program, the materials in the cooking cavity can be cooked in a targeted manner, so that the cooking equipment can automatically identify the type of the materials and automatically specify a targeted cooking process, and the automation and intelligence of the cooking equipment are improved.

[0072] The cooking equipment provided by the application can detect the electrical parameter of the material 300 through a simple circuit design and determine the type of the material 300 through the electrical parameter of the material 300, and determine the corresponding program according to the type of the material 300, and further control the cooking equipment to operate according to the corresponding program, so that the detection scheme is simple, the cost is low, and the processing resources required are few.

[0073] In some embodiments of the application, as shown in Figure 1 The electrical parameter includes the resistance value, the controller 100 includes a first detection end 202, the detection circuit 200 includes an input end 220 for receiving a voltage signal, a first resistor 216, a first end of the first resistor 216 is connected with the input end 220, and a second end of the first resistor 216 is connected with the first detection end 202, and a second resistor 218, a second end of the second resistor 218 is grounded.

[0074] In the embodiments of the application, the electrical parameter can include the resistance value, that is, the detection circuit 200 detects the resistance value of the material 300 in the cooking cavity. The controller 100 includes a first detection end 202, that is, the controller 100 is connected with the detection circuit 200 through the first detection end 202, further, the detection circuit 200 sends the detected resistance value to the controller 100 through the first detection end 202, and then the controller 100 determines the type of the material 300 according to the detected resistance value. The type of the material 300 is determined by using the resistance value of the material 300, which is more simple in structure and requires less processing resources. Specifically, the controller 100 needs to identify different material 300 types corresponding to different resistance values.

[0075] Specifically, the detection circuit includes an input end 220 for receiving a voltage signal, which can supply power to the detection circuit and is also a comparison signal for detecting the resistance of the material. The first resistor 216 is specifically a signal resistor of the detection circuit, and the second resistor 218 is specifically a grounding resistor. When the material 300 is placed in the cooking cavity, the equivalent resistance of the material will form a parallel connection with the first resistor 216, and the first resistor 216 and the second resistor 218 are in series. Therefore, the voltage signal input into the input end 220 will be divided by the first resistor 216, the second resistor 218 and the equivalent resistance of the material 300. At this time, the equivalent resistance of the material 300 can be calculated by detecting the voltage information at both ends of the first resistor 216, that is, the electrical parameter of the material 300 is obtained.

[0076] By detecting the resistance value of the material, the type of the material is determined, the cooking program is determined according to the type of the material, and the cooking device is controlled to work through the cooking program, so that the food in the cooking cavity can be cooked in a targeted manner, thereby enabling the cooking device to automatically identify the type of food and automatically specify a targeted cooking process, and improving the automation and intelligence of the cooking device.

[0077] In some embodiments of the present application, the detection circuit 200 further includes: a first detection member 204 connected to the first end of the first resistor 216; and a second detection member 206 connected to the second end of the first resistor 216.

[0078] In the embodiments of the present application, the first detection member and the second detection member are located in the cooking cavity, and when the material is placed in the cooking cavity, the material can simultaneously contact the first detection member and the second detection member. Specifically, the first detection member 204 and the second detection member 206 can be a probe, an electrode, a metal sheet, etc., and the material 300 is connected to the detection circuit 200 by connecting the first detection member 204 and the second detection member 206. By means of resistance voltage division, the controller 100 collects the voltage across the second resistor 218 through the first detection end 202, and it can be known from the formula that the voltage across the second resistor 218 will be different with the different resistance of the material 300; and then the resistance value of the material 300 is obtained by the formula using the voltage across the second resistor 218. The controller 100 obtains the resistance value of the material 300 and determines the type of the material 300.
