[0013] In the technical solution, after determining that the material of the cooking container is metal, it is determined whether the microwave cooking program in the current cooking program can be canceled. If the microwave cooking program in the current cooking program can be canceled, the microwave heating device is controlled or kept to stop working during the execution of the current cooking program. In the technical solution of the present invention, after determining that the material of the cooking container is metal, the microwave cooking program in the current cooking program is canceled (but other programs in the current cooking program are retained), thereby preventing the cooking device from performing microwave treatment on the metal cooking container, avoiding the user from mistakenly placing the metal cooking container into the cooking device for microwave heating, thereby damaging the cooking device, and improving the safety of the user in the process of using the cooking device.

[0014] In any of the above technical solutions, the control method of the cooking device also includes: stopping the execution of the current cooking program based on the fact that the microwave cooking program cannot be canceled during the current cooking program.

[0015] In the technical solution, after determining that the material of the cooking container is metal, it is determined whether the microwave cooking program in the current cooking program can be canceled. If the microwave cooking program in the current cooking program cannot be canceled, the current cooking program is stopped.

[0018] In any of the above technical solutions, determining the material information according to the distance specifically includes: determining that the cooking container is made of metal based on the distance being less than a preset threshold.

[0019] In this technical solution, a preset threshold is stored in advance. When the distance between the cooking container and the microwave distance measuring device detected by the microwave distance measuring device is less than the preset threshold, the cooking container is determined to be a metal material, and then the microwave heating device is controlled or maintained to stop working. In the technical solution of the present invention, the cooking container in the cooking cavity is determined to be a metal material when the microwave distance measuring device detects that the distance value is less than the preset threshold, thereby realizing the control of stopping the microwave heating device, thereby improving the accuracy of the entire cooking device control process.

[0052] A first aspect of the present invention provides a control method for a cooking device, wherein the cooking device includes a cooking cavity and a microwave heating device, and the microwave heating device is used to generate a first microwave to perform microwave heating on a cooking container placed in the cooking cavity.

[0053] Embodiment 1, Figure 1 A flow chart of a control method for a cooking device according to an embodiment of the present invention is shown. The control method for a cooking device includes:

[0054] Step 102, obtaining material information of the cooking container contained in the cooking cavity;

[0055] Step 104, controlling the operation of the microwave heating device according to the material information.

[0056] In this embodiment, the cooking device is provided with a cooking cavity and a microwave heating device, wherein the microwave heating device can generate a first microwave to heat a cooking container contained in the cooking cavity. In an embodiment of the present invention, the material of the cooking container contained in the cooking cavity is detected, and the working state of the microwave heating device is controlled by the material information of the cooking container obtained above. The present invention realizes the control of the working state of the microwave heating device by obtaining the material information of the cooking container contained in the cooking cavity, avoids the risk of arcing of the cooking device due to the use of an inappropriate cooking container during the microwave treatment of the cooking container by the cooking device, and ensures the safety and reliability of the microwave heating device of the cooking device during the microwave treatment of the cooking container.

[0057] In the above embodiment, controlling the operation of the microwave heating device according to the material information specifically includes: controlling or keeping the microwave heating device from operating based on the cooking container being made of metal.

[0058] In this embodiment, the material of the cooking container contained in the cooking cavity is detected, and if it is determined that the material of the cooking container is metal, the microwave heating device is controlled or maintained to stop working. In the embodiment of the present invention, by determining that the cooking container is made of metal, the microwave heating device is controlled to stop working, ensuring that when the cooking device performs microwave treatment on the metal cooking container, the microwave heating device can be controlled to stop working, avoiding arcs generated by the cooking device performing microwave treatment on the metal cooking container, thereby damaging the electronic components of the cooking device, increasing the service life of the cooking device, and ensuring the safety of the cooking device in the process of controlling the cooking container to perform microwave treatment.

[0059] In any of the above embodiments, based on the cooking container being made of metal, controlling or keeping the microwave heating device from working specifically includes: judging whether the microwave cooking program can be canceled in the current cooking program based on the cooking container being made of metal; and controlling or keeping the microwave heating device from working during the execution of the current cooking program based on the fact that the microwave cooking program can be canceled in the current cooking program.

[0060] In this embodiment, after determining that the material of the cooking container is metal, it is determined whether the microwave cooking program in the current cooking program can be canceled. If the microwave cooking program in the current cooking program can be canceled, the microwave heating device is controlled or maintained to stop working during the execution of the current cooking program. In the embodiment of the present invention, after determining that the material of the cooking container is metal, the microwave cooking program in the current cooking program is canceled (but other programs in the current cooking program are retained), thereby preventing the cooking device from performing microwave treatment on the metal cooking container, avoiding the user from mistakenly placing the metal cooking container into the cooking device for microwave heating, thereby causing damage to the cooking device, and improving the safety of the user in the process of using the cooking device.

[0061] It should be noted that in the above embodiment, when the microwave heating device is controlled or kept to stop working during the execution of the current cooking program, the cooking device will issue a prompt message to remind the user that the cooking container currently used is a metal container and needs to be replaced with a non-metal container, or to remind the user that the microwave cooking program in the current cooking program has been cancelled. The present invention does not limit the method of prompting information, and the method of prompting information can be voice prompt, indicator light prompt, display screen subtitle prompt, etc.

[0062] In any of the above embodiments, the control method of the cooking device further includes: stopping the execution of the current cooking program based on the fact that the microwave cooking program cannot be canceled during the current cooking program.

[0063] In this embodiment, after determining that the material of the cooking container is metal, it is determined whether the microwave cooking program in the current cooking program can be canceled. If the microwave cooking program in the current cooking program cannot be canceled, the current cooking program is stopped. In the embodiment of the present invention, after determining that the material of the cooking container is metal, the current cooking program is stopped by canceling the current cooking program, thereby preventing the cooking device from performing microwave treatment on the metal cooking container, avoiding damage to the cooking device when the user mistakenly puts the metal cooking container into the cooking device for microwave heating, improving the safety of the user in the process of using the cooking device, and further improving the safety of the cooking device control process.

[0064] It should be noted that in the above embodiment, when the current cooking program is stopped, the cooking device will send a prompt message to remind the user that the cooking container currently used is a metal container, so the microwave cooking program is cancelled from the current cooking program. The present invention does not limit the prompt message method, and the prompt message method can be a voice prompt, an indicator light prompt, a display screen subtitle prompt, etc.

[0065] In any of the above embodiments, obtaining the material information of the cooking container contained in the cooking cavity specifically includes: obtaining the distance between the microwave ranging device of the cooking equipment and the cooking container; and determining the material information according to the distance.

[0066] In this embodiment, a microwave distance measuring device is provided in the cooking cavity of the cooking device. In the embodiment of the present invention, after the cooking container is placed in the cooking device, the microwave distance measuring device of the cooking device is started to detect the distance between the cooking container in the cooking device and the microwave distance measuring device, and then the material information of the cooking container is determined by the detected distance. The present invention determines the material information of the cooking container by obtaining the distance between the microwave distance measuring device of the cooking device and the cooking container, and then controls the working state of the microwave heating device by the material information obtained, thereby ensuring the rationality and intelligence of the entire cooking device control process.

[0067] In any of the above embodiments, determining the material information according to the distance specifically includes: determining that the cooking container is made of metal based on the distance being less than a preset threshold.

[0068] In this embodiment, a preset threshold is stored in advance. When the distance between the cooking container and the microwave distance measuring device detected by the microwave distance measuring device is less than the preset threshold, the cooking container is determined to be a metal material, and then the microwave heating device is controlled or maintained to stop working. In the embodiment of the present invention, the cooking container in the cooking cavity is determined to be a metal material by the microwave distance measuring device detecting that the distance value is less than the preset threshold, thereby realizing the control of stopping the microwave heating device, thereby improving the accuracy of the entire cooking device control process.

[0069] In any of the above embodiments, after obtaining the distance between the microwave ranging device of the cooking device and the cooking container, the method further includes: determining that the cooking cavity is empty based on the distance being equal to a preset threshold; and determining that the cooking container is made of a non-metal material based on the distance being greater than the preset threshold.

[0070] In this embodiment, when the distance between the cooking container detected by the microwave ranging device and the microwave ranging device is equal to the preset threshold, it is determined that the cooking cavity is empty, that is, no cooking container has been placed in the cooking device. When the distance between the cooking container detected by the microwave ranging device and the microwave ranging device is greater than the preset threshold, it is determined that the cooking container is made of a non-metal material. In the embodiments of the present invention, on the one hand, after determining that the cooking cavity is in an empty state by detecting that the distance value detected by the microwave ranging device is equal to the preset threshold, the cooking device is controlled not to work, preventing the cooking device from being accidentally turned on and causing ineffective operation of the cooking device and wasting resources when no cooking container is placed, ensuring the effectiveness of the cooking device throughout the control process. On the other hand, after determining that the cooking container in the cooking cavity is made of a non-metal material by detecting that the distance value detected by the microwave ranging device is greater than the preset threshold, the cooking device is controlled to execute the cooking program to work and perform microwave heating on the cooking container, ensuring the practicality of the entire cooking device control process.

[0071] Specifically, microwave refers to an electromagnetic wave with a frequency ranging from 300 MHz to 300 GHz, which is a short name for a limited frequency band in radio waves. The basic properties of microwaves usually exhibit three characteristics: penetration, reflection, and absorption. For glass, plastic, and porcelain, microwaves almost pass through without being absorbed. For water and food, etc., they will absorb microwaves and heat themselves. For metal objects, microwaves will be reflected.

[0072] When the cooking device is empty, after the microwave is emitted, it is reflected back from the cooking cavity wall opposite the microwave ranging sensor. That is, the distance measured by the microwave ranging sensor is the height or width D of the internal cavity of the cooking device. Therefore, D is a known fixed parameter, and the cooking device pre-stores D in the processing chip. When the cooking container used is a non-metal container, the microwave penetrates the non-metal container after being emitted and enters the food interior, where it is absorbed by the food, and very little microwave is reflected back, which is equivalent to being unable to measure the distance, that is, the distance is infinite. When the cooking container used is a metal container, after the microwave is emitted, it returns when it encounters the metal container at the middle position of the cooking cavity, and the measured distance is d, where d < D. Considering the above several situations, when the microwave sensor measures a distance d < D, it can be determined that the current user is using a metal container.

[0073] In any of the above embodiments, obtaining the material information of the cooking container accommodated in the cooking cavity specifically includes: collecting the image information of the cooking container; and determining the material information according to the image information.

[0074] In this embodiment, an image acquisition device is provided in the cooking cavity of the cooking device. In the embodiment of the present invention, after the cooking container is placed in the cooking device, the image acquisition device of the cooking device is controlled to acquire image information of the cooking container in the cooking device, and then the material information of the cooking container is determined through the acquired image information. The present invention determines the material information of the cooking container by acquiring the image information of the cooking container in the cooking device, and then controls the working state of the microwave heating device through the acquired material information, thereby ensuring the rationality and intelligence of the entire cooking device control process.

[0075] It should be noted that the cooking device of the present invention pre-stores material information of various cooking containers, wherein the material information includes: the density of the cooking container corresponding to the cooking containers of various materials. The cooking device obtains the weight and volume of the cooking container through the image acquisition device, and then determines the density of the cooking container, and determines the material of the cooking container by comparing the obtained density of the cooking container with the pre-stored material information of the cooking container.

[0076] Embodiment 2: Figure 2 The second flow chart of the control method of the cooking device according to the embodiment of the present invention is shown. The control method of the cooking device includes:

[0077] Step 202, receiving a cooking instruction and determining a current cooking program;

[0078] Step 204, determining whether the current cooking program includes a microwave cooking program, if the current cooking program includes a microwave cooking program, proceeding to step 206, otherwise proceeding to step 210;

[0079] Step 206, obtaining material information of the cooking container contained in the cooking cavity;

[0080] Step 208, controlling the operation of the microwave heating device according to the material information;

[0081] Step 210, executing the current cooking program.

[0082] In this embodiment, the cooking device first receives a cooking instruction and determines the current cooking program based on the cooking instruction. If the current cooking program includes a microwave cooking program, the step of obtaining material information of the cooking container contained in the cooking cavity is entered, thereby ensuring the accuracy of the cooking device during the entire control process.

[0083] In this embodiment, if the current cooking program does not include a microwave cooking program, the cooking device continues to execute the current cooking program, thereby avoiding the step of obtaining material information of the cooking container contained in the cooking cavity when microwave processing is not needed in the cooking device, thereby avoiding the cooking device from executing redundant programs and ensuring the accuracy of the cooking device during the control process.

[0084] Embodiment 3, Figure 3 The third flow chart of the control method of the cooking device according to the embodiment of the present invention is shown. The control method of the cooking device includes:

[0085] Step 302, the user starts the cooking program;

[0086] Step 304, determining whether the microwave function needs to be enabled for the current menu, if yes, proceeding to step 306, if no, proceeding to step 322;

[0087] Step 306, start the microwave ranging sensor;

[0088] Step 308, the measured distance is d;

[0089] Step 310, determine whether the measured distance d is less than D, if yes, proceed to step 312, if no, proceed to step 320;

[0090] Step 312, determining that the cooking container currently in use is a metal container;

[0091] Step 314, determining whether the microwave function in the current menu is a required program function, if yes, proceeding to step 316, if no, proceeding to step 318;

[0092] Step 316, prohibiting cooking and reminding the user to replace the non-metal container;

[0093] Step 318, start cooking, and turn off the microwave function during the cooking process;

[0094] Step 320, determining that the cooking container currently in use is a non-metal container;

[0095] Step 322, start cooking normally.

[0096] In this embodiment, after the user starts the cooking program, it is determined whether the microwave function needs to be enabled in the menu of the current program. When it is determined that the microwave function needs to be enabled, the cooking device first enables the microwave distance sensor. The microwave distance sensor measures different distances d according to different scenarios. Then, according to the above-mentioned measured distance d and D are compared, if d is less than D, it is determined that the cooking container currently in use is a metal container, and if d is greater than D, it is determined that the cooking container currently in use is a non-metal container. When the cooking container currently in use is a metal container, it is determined whether the microwave function in the current menu is a required program function. If the microwave function is a required program function, cooking is prohibited and the user is reminded to replace the non-metal container. If the microwave function is a non-required program function, cooking is started and the microwave function is turned off during the cooking process. When the cooking container currently in use is a non-metal container, the cooking function is started normally.

[0097] It should be noted that when the use of a metal container is detected, two operations are implemented: for menus that must use the microwave function, cooking is prohibited and the user is reminded to change the container; for menus that do not require the microwave function to be enabled, the microwave function is automatically turned off during the cooking process.
