Description

Technical Field

[0001] This application relates to the field of home appliance technology, such as a method, apparatus, and microwave oven for controlling a microwave oven. Background Technology

[0002] With the ever-accelerating pace of life, the automatic heating and cooking of food is a crucial issue to address in achieving smart living. To directly heat food inside a microwave oven, current technology incorporates a semiconductor cooling module. This module cools the food within the microwave, extending its shelf life and allowing users to pre-heat it after a preset time. However, existing microwave ovens typically place the heating module in the center for even heating, often placing the cooling module on the side wall or side. This can cause cold air to concentrate around the cooling module, resulting in uneven cooling and affecting food preservation.

[0003] In the process of implementing the embodiments of this disclosure, it was found that at least the following problems exist in the related technology: different foods are suitable for different degrees of cooling balance, and existing microwave ovens cannot provide a suitable degree of cooling balance for different foods. Summary of the Invention

This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] This disclosure provides a method, apparatus, and microwave oven for controlling a microwave oven to provide a suitable and balanced cooling level for different foods.

[0008] Acquire an image of the food inside the microwave oven;

[0009] The rotation speed of the tray is determined based on the image of the food;

[0010] The tray is triggered to rotate according to the rotation speed.

[0011] In some embodiments, the apparatus for controlling a microwave oven includes a processor and a memory storing program instructions, the processor being configured to execute the method for controlling a microwave oven as described above when executing the program instructions.

[0012] In some embodiments, the microwave oven includes the aforementioned means for controlling the microwave oven.

[0013] The method, apparatus, and microwave oven for controlling a microwave oven provided in this disclosure can achieve the following technical effects: when food is placed in the microwave oven, the semiconductor cooling module is triggered to cool and the microwave heating module is triggered to stop working; an image of the food inside the microwave oven is acquired; the rotation speed of the tray is determined based on the image of the food; the tray is triggered to rotate according to the rotation speed, so that the tray can drive the food on the tray to rotate, causing airflow inside the microwave oven, making the cooling of the microwave oven more even. At the same time, since the degree of cooling evenness is different for different rotation speeds, it can provide a suitable degree of cooling evenness for different foods.

[0028] The method for controlling a microwave oven provided in this disclosure, when food is placed inside the microwave oven, triggers a semiconductor cooling module to cool and triggers a microwave heating module to stop working. It also determines the rotation speed of the tray and, when the semiconductor cooling module is cooling, triggers the tray to rotate according to this rotation speed. This causes the tray to rotate, resulting in airflow inside the microwave oven, making the cooling more even. Furthermore, since different rotation speeds correspond to different degrees of cooling evenness, it can provide a suitable degree of cooling evenness for different foods.

[0029] Optionally, the microwave oven includes a camera device. Optionally, the camera device acquires an image of the microwave oven's interior; based on the image, it is determined whether food is placed inside the microwave oven.

[0030] Optionally, the microwave oven includes an image recognition device. The image recognition device identifies the image inside the microwave oven cavity and determines whether there is food in the image based on the recognition result. Optionally, the pixel values ​​of corresponding pixels in the microwave oven cavity image to be identified are compared with those in a preset initial background image. If the difference in pixel values ​​between a set number of pixels is greater than or equal to a set threshold, it is determined that there is food in the microwave oven cavity image to be identified; if the difference in pixel values ​​between a set number of pixels is less than a set threshold, it is determined that there is no food in the microwave oven cavity image to be identified. Optionally, the initial background image is the image inside the microwave oven cavity when there is no food inside.

[0031] Optionally, the presence of food inside the microwave oven can be determined by the difference in reflection between food and the microwave oven cavity detected by sensors such as infrared and ultrasonic sensors. The presence of food inside the microwave oven can be detected by a combination of one or more of the following sensors: infrared sensor, radar, laser sensor, and ultrasonic sensor. Optionally, the presence of food inside the microwave oven can be detected by the signal reflection detected by the sensors. Optionally, if the signal reflection information detected by the sensors inside the microwave oven differs from preset signal reflection information, it is determined that food is inside the microwave oven.

[0032] Optionally, triggering the semiconductor cooling module to perform cooling includes: triggering the semiconductor cooling module to perform cooling at the cooling temperature corresponding to the first preset time period at different first preset time periods.

[0033] Optionally, triggering the semiconductor cooling module to cool at the cooling temperature corresponding to the first preset time period at different first preset time periods includes: acquiring food images inside the microwave oven; performing image recognition on the food images to obtain the food type in the food images; matching the cooling temperature corresponding to the food type and the cooling time period corresponding to the cooling temperature in a preset cooling temperature database; the cooling temperature database stores the correspondence between food type, cooling temperature, and cooling time period; determining the matched cooling time period as the first preset time period, and cooling at the cooling temperature corresponding to the first preset time period according to the first preset time period. In some embodiments, an example table of the cooling temperature database is shown in Table 1.

[0034] Table 1

[0035]

[0036]

[0037] In some embodiments, as shown in Table 1, when the food type is pork, the corresponding cooling temperature is -4. 0 The corresponding cooling time period is 3 minutes, meaning the first preset time period is 3 minutes. For example, when cooling pork, the microwave oven receives a cooling command, the microwave oven's semiconductor cooling module begins cooling, and within 3 minutes, it cools at -4... 0 The cooling temperature is set to -2 degrees Celsius. For fish, the appropriate cooling temperature is -2 degrees Celsius. 0 The corresponding cooling time is 2 minutes. When the food type is a hamburger, the corresponding cooling temperature is 4. 0 The corresponding cooling time period is 0.5 minutes.

[0038] Optionally, determining the tray rotation speed based on the food image includes: performing image recognition on the food image to obtain the food type in the image; and determining the tray rotation speed based on the food type. Optionally, an image inside the microwave oven cavity when there is food inside the microwave oven can be used as the food image.

[0039] Optionally, an image of food inside the microwave oven is acquired using a camera device. Optionally, the food image is identified to determine the food type, including: extracting features from the food image to be identified; extracting features from reference images corresponding to each food type in a preset food type database; comparing the features of the food image to be identified with the features of the reference images in the food type database to obtain a reference image that matches the food image to be identified; and determining the food type corresponding to the matched reference image as the food type of the food image to be identified; wherein the food type database stores reference images corresponding to each food type.

[0040] Optionally, the rotation speed of the tray is determined according to the type of food, including: matching the rotation speed corresponding to the type of food in a preset rotation speed data table, wherein the rotation speed data table stores the correspondence between food types and rotation speeds.

[0041] Optionally, the tray is triggered to rotate based on the rotation speed, including: triggering the tray to rotate at a preset rotation speed for a preset rotation time; the rotation time is determined based on the image of the food.

[0042] Optionally, determining the rotation time based on the food image includes: performing image recognition on the food image to determine the food type; and determining the rotation time based on the food type. Since different foods are cooled to varying degrees at different rotation times, obtaining the rotation time corresponding to the food type and triggering the tray to rotate according to the rotation time corresponding to the food type enables targeted cooling for different foods.

[0043] Optionally, the rotation time is determined based on the type of food, including: matching the rotation time corresponding to the type of food in a preset rotation time database; the rotation time database stores the correspondence between the types of food and the rotation time.

[0044] Optionally, after the tray is triggered to rotate according to the rotation speed, the method further includes: upon receiving a defrosting command, triggering the semiconductor refrigeration module to cool according to a preset energizing current and triggering the microwave heating module to enter the microwave defrosting state; the energizing current is determined according to the microwave defrosting time: matching the semiconductor refrigeration module energizing current corresponding to the microwave defrosting time in a preset energizing current database; the energizing current database stores the correspondence between the microwave defrosting time and the semiconductor refrigeration module energizing current.

[0045] In this way, the semiconductor cooling module cools the food according to the preset energizing current during thawing, which can prevent the outer surface of the food from overheating and causing the outside to burn while the inside remains frozen.

[0046] Optionally, after the tray is triggered to rotate according to the rotation speed, the method further includes: upon receiving a defrosting command, switching the direction of the energizing current of the semiconductor cooling module; and after a preset time interval, triggering the microwave heating module to enter the microwave defrosting state and triggering the semiconductor cooling module to stop working. In this way, switching the energizing current of the semiconductor cooling module causes the cooling end of the semiconductor cooling module to heat up, which facilitates a rapid increase in the temperature inside the microwave oven and accelerates the defrosting efficiency of the food inside the microwave oven.

[0047] Optionally, when the semiconductor cooling module is in cooling mode, the user's location and the corresponding duration are obtained; the user's location and the corresponding duration are input into a preset microwave oven heating prediction model to obtain the probability that the user will heat food in the microwave oven; and the microwave oven heating is controlled based on the probability that the user will heat food in the microwave oven. Alternatively, the user's location and the corresponding duration are obtained; the user's location and the corresponding duration are input into a preset microwave oven heating prediction model to obtain the probability that the user will heat food in the microwave oven within a preset time period; and the semiconductor cooling module of the microwave oven is triggered to stop cooling and the microwave oven heating is controlled based on the probability that the user will heat food in the microwave oven.

[0048] Optionally, if the probability of a user heating food in the microwave oven within a preset time period reaches a set threshold, the microwave oven is controlled to heat. Optionally, if the probability of a user heating food in the microwave oven within a preset time period reaches a set threshold, the microwave oven's semiconductor cooling module is triggered to stop cooling and the microwave oven is controlled to heat. Optionally, if the probability of a user heating food in the microwave oven within a preset time period does not reach the set threshold, the microwave oven's semiconductor cooling module is controlled to remain in cooling mode. Optionally, if the probability of a user heating food in the microwave oven within a preset time period does not reach the set threshold, the microwave oven's semiconductor cooling module is controlled to continue cooling and the current of the semiconductor cooling module is increased.

[0049] Optionally, the microwave oven heating prediction model is trained in the following way:

[0050] Training samples are acquired, each including the user's location and the corresponding duration. Each user location carries a label representing the microwave oven's on / off status within a preset time period after the user's location is acquired. Based on these training samples, an initial neural network model is trained to obtain a microwave oven heating prediction model. Optionally, the microwave oven's on / off status is obtained through a microwave oven door opening detection circuit. In some embodiments, the microwave oven's on / off status is either on or off. Obtaining the microwave oven's on / off status through a microwave oven door opening detection circuit is a mature existing technology and will not be elaborated upon here.

[0051] Optionally, the user's location can be obtained through a user positioning device. Optionally, the user positioning device is an infrared human body sensor.

[0052] Optionally, obtaining the user's location through a user positioning device includes: matching the location information corresponding to the user positioning device that detected the user in a preset database, that is, matching the location information corresponding to the user positioning device, which detected the user; and using the location information as the user's location. The database stores the correspondence between user positioning devices and location information. Optionally, the location information is the location of the user positioning device. In some embodiments, the user positioning device detects a human body, which is considered as the user positioning device detecting the user. Optionally, when multiple user positioning devices detect the user, the location information of any one of the user positioning devices is used as the user's location.

[0053] Optionally, after a human body is detected by the infrared human body sensor, the time when the human body is detected by the infrared human body sensor is determined as the first time point, the time after the first time point when the human body is not detected by the infrared human body sensor is determined as the second time point, and the time period between the first time point and the second time point is determined as the duration corresponding to the user's location.

[0054] The advent of microwave ovens has changed people's lifestyles. Users are increasingly accustomed to placing food in microwave ovens that can refrigerate in advance. However, if the microwave oven stops refrigerating and starts heating food after its set time, and the user doesn't remove the heated food promptly, it can easily spoil. The solution described above uses a user positioning device to detect the user's location. A microwave oven heating prediction model, obtained through training samples including the user's location and the corresponding duration, can correlate the user's historical trajectory data with the microwave oven's on / off status. This allows the model to predict the likelihood of the user heating food in the microwave oven within a preset time period based on the user's location and the duration of that location. If the prediction indicates the user will heat food in the microwave oven within the preset time period, the model controls the microwave oven to heat or triggers the semiconductor refrigeration module to stop refrigeration and control the microwave oven to heat, ensuring timely heating of the food and improving the user's microwave oven experience.

[0055] Combination Figure 2 As shown, this disclosure provides an apparatus for controlling a microwave oven, including a processor 100 and a memory 101 storing program instructions. Optionally, the apparatus may further include a communication interface 102 and a bus 103. The processor 100, communication interface 102, and memory 101 can communicate with each other via the bus 103. The communication interface 102 can be used for information transmission. The processor 100 can call the program instructions in the memory 101 to execute the method for controlling a microwave oven described in the above embodiment.

[0056] When food is placed inside the microwave oven, the semiconductor cooling module is triggered to cool and the microwave heating module is stopped. The rotation speed of the tray is determined, and the tray is triggered to rotate according to the rotation speed when the semiconductor cooling module is cooling. This causes the food on the tray to rotate, which causes air to flow inside the microwave oven, making the microwave oven cool more evenly and the food cools more evenly.

[0057] Furthermore, the program instructions in the aforementioned memory 101 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.

[0058] The memory 101, as a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as program instructions / modules corresponding to the methods in the embodiments of this disclosure. The processor 100 executes functional applications and data processing by running the program instructions / modules stored in the memory 101, that is, it implements the method for controlling the microwave oven in the above embodiments.

[0059] The memory 101 may include a program storage area and a data storage area. The program storage area may store the operating system and applications required for at least one function; the data storage area may store data created based on the use of the terminal device. Furthermore, the memory 101 may include high-speed random access memory and may also include non-volatile memory.

[0060] Using the device for controlling a microwave oven provided in this embodiment, when food is placed inside the microwave oven, the semiconductor cooling module is triggered to cool and the microwave heating module is triggered to stop working. The rotation speed of the tray is determined, and the tray is triggered to rotate according to the rotation speed when the semiconductor cooling module is cooling.
