A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household appliance product that keeps food or other items in a constant low-temperature cold state. However, in line with the progress of social civilization, people have higher and higher requirements for the functionality of daily necessities and prefer a high-tech lifestyle, making the living environment and daily operations reflect a high degree of modernity, comfort, and pleasure. During the process of cooking dishes, it is often necessary to refer to a recipe. The traditional solution is to buy relevant recipe books and operate according to the steps described in the book when cooking. In this way, the requirements can be basically met, but the use process is inconvenient. It is necessary to operate while looking at the book, and the process is cumbersome and cramped. There are often interferences between the reference and execution actions, delaying the cooking time and resulting in cooking failure.

[0003] The related technology discloses an intelligent refrigerator and a method for realizing recipe recommendation. It solves the problem that the existing refrigerator cannot provide functions such as ingredient management and recipe recommendation. The intelligent refrigerator includes a main controller disposed inside the refrigerator body. The main controller is controlled and connected to a touch control display screen disposed on the surface of the refrigerator body. The main controller is controlled and connected to a network transmission port. The network transmission port is wirelessly connected to a remote server through a wireless network. The main controller is controlled and connected to an infrared barcode scanner. The main controller is controlled and connected to a barcode printer.

[0039] At present, with the continuous improvement of living standards, people pay more and more attention to diet health. A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household electrical appliance product that keeps food or other items in a constant low-temperature cold state. However, with the progress of social civilization, people have higher and higher requirements for the functionality of daily necessities and tend to a high-tech lifestyle, making the living environment and daily operations reflect a high degree of modernity, comfort, and pleasure. During the process of cooking dishes, it is often necessary to refer to recipes. The traditional solution is to buy relevant recipe books and operate according to the steps introduced in the books when cooking. In this way, the requirements can be basically met, but the use process is not convenient. It is necessary to operate while looking at the book, and the process is cumbersome and cramped. There are often interferences between the reference and execution actions, delaying the cooking time and resulting in cooking failures. Related technologies have disclosed an intelligent refrigerator and a method for realizing recipe recommendations. It solves the problem that existing refrigerators cannot provide functions such as ingredient management and recipe recommendations. The intelligent refrigerator includes a main controller disposed inside the refrigerator body. The main controller is controlled and connected to a touch control display screen disposed on the refrigerator body surface. The main controller is controlled and connected to a network transmission port. The network transmission port is connected to a remote server through a wireless network.

The method for realizing recipe recommendations includes: an ingredient entry step, a recipe recommendation step, and an ingredient deletion step. The present invention adds functions of electronic information management of ingredients and electronic recipe recommendations on the refrigerator body, and can also upload self-created dishes for more users to refer to, thereby expanding the number of recipe references for dish making, facilitating the making and quality standardization of dishes, and enhancing the comfort and pleasure of kitchen operations. When using the related technology label printer to print ingredient labels, it needs to be connected to the screen terminal. In the actual application process, due to energy conservation needs, the label printer is not always in an on state, which results in that when the user prints ingredient labels, the user needs to manually select the label printer to be connected on the screen terminal. However, it takes a long time from the label printer being turned on to establishing a connection with the screen terminal, resulting in a long waiting time for the user and a poor user experience.

[0040] The embodiments of the present disclosure disclose a refrigerator, including a display screen, a label printer, a communication module, a voice recognition module, a human sensing module, and a processor. The human sensing module includes a detection device for detecting the user's position. The detection device includes a first detection device and a second detection device spaced at a set height. Among them, the first detection device and the second detection device can be radio frequency sensors. The processor is electrically connected to the above-mentioned electrical components and is used to control the above-mentioned electrical components to perform actions.

[0041] Based on the structure of the refrigerator as described above, as Figure 1 shown, the embodiments of the present disclosure provide a method for controlling a refrigerator, including:

[0042] S01. When the duration between the time when the user last used the label printer and the current time is greater than the first duration threshold, the processor controls the label printer to turn off.

[0043] S02. When the label printer is turned off, based on the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator, the processor determines whether the user has the intention to print a label.

[0044] S03. When it is determined that the user has the intention to print a label, the processor controls the display screen to connect to the label printer.

[0045] Among them, the first duration threshold can be any duration, for example, 10 minutes, 11 minutes, or 12 minutes, etc. Specifically, the first duration threshold can be determined according to the power consumption and battery level of the label printer. The greater the power consumption and the lower the battery level, the smaller the first duration threshold; conversely, the larger it is.

[0046] Using the method for controlling a refrigerator provided by the embodiments of the present disclosure, when the duration between the time when the user last used the label printer and the current time is greater than the first duration threshold, for energy conservation, the processor controls the label printer to turn off. When the label printer is turned off, based on the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator, it is determined whether the user has the intention to print a label. When it is determined that the user has the intention to print a label, the display screen is controlled to connect to the label printer. When the label printer is turned off for energy conservation, the user's intention is recognized based on the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator, so that before the user prints a label, the connection between the label printer and the screen terminal is established in advance, realizing a seamless connection between the label printer and the screen terminal. Thus, when the user prints a food ingredient label, the situation of the user waiting for a long time is avoided, and the user experience is improved.

[0047] Based on the above structure of the refrigerator, as Figure 2 shown, the embodiments of the present disclosure provide a method for controlling a refrigerator, including:

[0048] S01. When the duration between the time when the user last used the label printer and the current time is greater than the first duration threshold, the processor controls the label printer to turn off.

[0049] S21. When the label printer is turned off, the processor obtains the user's location information and / or the user's voice information and / or the interface information of the display screen.

[0050] S22. When the user's location information and / or the user's voice information and / or the interface information of the display screen meet the preset conditions, the processor determines that the user has the intention to print a label.

[0051] S03. When it is determined that the user has the intention to print a label, the processor controls the display screen to connect to the label printer.

[0052] When using the method for controlling a refrigerator provided by the embodiments of the present disclosure, when the label printer is turned off, the label printer is in a power-saving state. It is necessary to judge in advance whether the user has a printing intention, so as to judge whether to connect the screen terminal and the label printer in advance. Therefore, the processor obtains the location information of the user and / or the voice information of the user and / or the interface information of the display screen. When the location information of the user and / or the voice information of the user and / or the interface information of the display screen meet the preset conditions, the processor determines that the user has the intention to print a label.

[0053] Optionally, the preset conditions include: the user is within the set range; and / or, the user emits a voice with a printing intention; and / or, the display screen enters the printing interface.

[0054] In this way, when the user is within the set range, the user is relatively close to the refrigerator screen terminal and has the intention to print food ingredient labels. When the user issues a voice command to print food ingredient labels or the display screen enters the printing interface, it indicates that the user clearly has the intention to print food ingredient labels. Therefore, when the user is within the set range and / or the user emits a voice with a printing intention and / or the display screen enters the printing interface, it can be determined that the user has the intention to print food ingredient labels.

[0055] Optionally, as Figure 3 shown, the processor judges whether the user is within the set range according to the following method:

[0056] S31. When the user is within the recognition range of the detection device, the processor respectively obtains the first detection value of the first detection device and the second detection value of the second detection device.

[0057] S32. The processor calculates the parameter difference between the first detection value and the second detection value.

[0058] S33. When the parameter difference is less than the error threshold, the processor determines that the user is within the set range.

[0059] Wherein, the first detection device and the second detection device are spaced apart by a set height. Since the body proportions of different users are different, some have long legs, some have short legs, some have long upper bodies, and some have short upper bodies. By spacing the set height, the detection parameters of the two detection devices can be adapted to the body conditions of different users, so that the detection results can be more accurate.

[0060] In this way, when the user is within the recognition range of the detection device, the first detection value of the first detection device and the second detection value of the second detection device are respectively obtained, and the parameter difference between the first detection value and the second detection value is calculated. Finally, when the parameter difference is less than the error threshold, the user is determined to be within the set range based on the first detection value and the second detection value. By setting two detection devices and comparing the consistency of the detection values of the two detection devices, it is possible to accurately identify whether the moving object within the recognition range is only the user. This reduces the interference of the movable device on the detection device when identifying the user, thereby improving the accuracy of user identification.

[0061] Optionally, the processor determines the set height according to the following method: The processor obtains the body information of the user; The processor determines the set height corresponding to the body information according to the preset correspondence between the body information and the set height.

[0062] Among them, the correspondence can be determined by looking up a table, introducing expert knowledge, or determined by developers.

[0063] In this way, determining the set height based on the body information of the user can make the set height match the user's figure.

[0064] Optionally, the processor determines the error threshold according to the following method: The processor obtains the first height of the first detection device and the second height of the second detection device; The processor determines the error threshold according to the first height and the second height.

[0065] In this way, since the detection devices are placed at different heights and the recognition ranges may be different, resulting in reasonable errors in the detection results of each parameter, the processor determines the error threshold through the first height and the second height, which can make the error threshold more accurate.

[0066] Optionally, the processor determines the error threshold according to the first height and the second height, including: The processor calculates the height difference between the first height and the second height; The processor determines the error threshold corresponding to the height difference according to the preset correspondence between the height difference and the error threshold.

[0067] In this way, since the difference between the first height and the second height can affect the interval between the recognition ranges of the first detection device and the second detection device, the processor determines the error threshold according to the preset height difference, which can further improve the accuracy of the error threshold.

[0068] Optionally, the processor determines the first height according to the following method: The processor obtains the size information of the movable device in the user's home; The processor determines the first height according to the size information of the movable device; where the first height is less than the second height.

[0069] Among them, the dimension information includes information such as the length, width, and height of the movable device. The first height is greater than the height of the movable device.

[0070] In this way, in order to avoid the interference of the movable device to the detection device, it is necessary to make the height of the effective recognition range of the first detection device greater than the height of the movable device, so that the first detection device cannot detect the movable device, thereby reducing the interference of the movable device in the home. Therefore, determining the first height according to the dimension information of the movable device can make the first height more accurate and improve the accuracy of user recognition.

[0071] Based on the above structure of the refrigerator, as Figure 4 shown, the embodiments of the present disclosure provide a method for controlling a refrigerator, including:

[0072] S01, when the duration between the time when the user last used the label printer and the current time is greater than the first duration threshold, the processor controls the label printer to shut down.

[0073] S02, when the label printer shuts down, the processor determines whether the user has the intention to print a label according to the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator.

[0074] S41, when it is determined that the user has the intention to print a label, the processor detects whether the label printer is powered on.

[0075] S42, when the label printer is not powered on, the processor controls the printer to be powered on.

[0076] S43, when the label printer is powered on, the processor controls the display screen to be connected to the label printer.

[0077] By using the method for controlling a refrigerator provided by the embodiments of the present disclosure, when it is determined that the user has the intention to print a label, the processor detects whether the label printer is powered on to determine whether the label printer can be normally started. When the label printer is not powered on, the processor controls the printer to be powered on so that the label printer can be normally started. When the label printer is powered on, the processor controls the display screen to be connected to the label printer, so that the user can control the label printer to print a label through the display screen.

[0078] Optionally, the processor controls the display screen to be connected to the label printer, including: the processor determines the start connection time for the display screen to be connected to the label printer according to the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator; when the start connection time arrives, the processor controls the display screen to start connecting to the label printer.

[0079] Among them, the processor determines the start connection time for the display screen to connect to the label printer according to the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator. Specifically, the duration required for the user to reach the screen end from entering the recognition range of the detection device and start using the label printer to print food ingredient labels under the current environmental parameters and / or operating parameters can be determined through a preset corresponding relationship. Thus, the processor can calculate and determine the start connection time based on the required duration and the current time. For example, when the user is within the set range, or when the user issues a voice command with the intention of printing, the processor adds the duration required to reach the screen end and start using the label printer to print food ingredient labels to the current time, and then subtracts the duration required for the label printer to connect to the display screen, thereby obtaining the start connection time; when the display screen enters the printing interface, the processor directly uses the current time as the start connection time for the display screen to connect to the label printer, etc. The start connection time can be any time, as long as the label printer is connected to the display screen when the user reaches the screen end to use the label printer, and there is no limitation here. The duration required for the label printer to connect to the display screen can be specifically determined by querying through a preset corresponding relationship according to the model of the label printer and the signal of the refrigerator.

[0080] In this way, the processor determines the start connection time for the display screen to connect to the label printer according to the environmental parameters around the refrigerator and / or the operating parameters of the refrigerator. When the start connection time is reached, the processor controls the display screen to start connecting to the label printer, so that the start connection time of the label printer and the display screen matches the time when the user reaches the screen end, thereby enabling the user to use the label printer when they need to print food ingredient labels, reducing the waiting time of the user.

[0081] Combined with Figure 5 As shown, an apparatus 800 for controlling a refrigerator provided by an embodiment of the present disclosure includes a processor 801 and a memory 802. Optionally, the apparatus may further include a communication interface 803 and a bus 804. Among them, the processor 801, the communication interface 803, and the memory 802 can complete communication with each other through the bus 804. The communication interface 803 can be used for information transmission. The processor 801 can call the logical instructions in the memory 802 to execute the method for controlling the refrigerator in the above embodiment.

[0082] In addition, when the logical instructions in the above-mentioned memory 802 are implemented in the form of a software functional unit and sold or used as an independent product, they can be stored in a computer-readable storage medium.

[0083] The memory 802, being a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as the program instructions / modules corresponding to the methods in the embodiments of the present disclosure. The processor 801 executes functional applications and data processing by running the program instructions / modules stored in the memory 802, that is, implements the method for controlling the refrigerator in the above embodiments.
