Description

Technical Field

[0001] This application relates to refrigerator technology. More specifically, it relates to a refrigerator control method, a refrigerator, a storage medium, and a program product. Background Technology

[0002] A refrigerator consists of a door and a cabinet. The door or cabinet may be equipped with interactive components such as touch buttons or touch screens to control the refrigerator's functions.

[0003] Currently, refrigerators on the market often use offline demonstrations to boost sales. During these demonstrations, consumers try to interact with the refrigerator's controls by touching the interactive components or open the doors to see the interior. However, these experiences require the refrigerator to be powered on. If the cooling function is also activated after powering on, frequent opening and closing leads to significant energy waste and severely reduces the lifespan of the cooling system, rendering the refrigerator unsellable and resulting in a serious waste of resources. Therefore, existing refrigerators typically have a "store mode." In this mode, the buttons, interactive components, lights, and other electrical parts operate normally, but the cooling system does not. This allows the refrigerator to remain usable by consumers even after becoming a display model.

[0004] Currently, refrigerators set to retail mode require manual switching to normal operating mode for proper cooling. However, after being sold to consumers, refrigerators on display are frequently forgotten to switch modes, or consumers may accidentally trigger retail mode without realizing it. Furthermore, consumers may not know how to switch back to normal cooling mode, leading to numerous complaints and a diminished user experience. Summary of the Invention

[0005] This application provides a refrigerator control method, a refrigerator, a storage medium, and a program product, which can solve the problem that after the refrigerator is sold to consumers, they often forget to switch modes, or the store mode is accidentally triggered during consumer use without their knowledge. Furthermore, consumers may not know how to switch to the normal cooling mode, resulting in consumers not being able to achieve normal cooling after purchasing the refrigerator, generating a large number of complaints, and reducing the consumer's user experience.

[0006] In a first aspect, embodiments of this application provide a refrigerator, the refrigerator comprising:

[0007] Storage room;

[0008] The first sensor is installed inside the storage room to detect the temperature inside the storage room;

[0009] A refrigeration system is used to lower the temperature of the storage room.

[0010] A control device is connected to the first sensor and the refrigeration system respectively. The control device is used to control the refrigeration system to cool down the storage room when the temperature detected by the first sensor does not meet the preset temperature.

[0011] The control device is also used for:

[0012] If the refrigeration system fails to cool down, determine whether the refrigerator is in the first functional mode;

[0013] When the refrigerator is in the first functional mode, a prompt message indicating that the refrigerator is in the first functional mode is output; in the first functional mode, the refrigerator does not start the refrigeration system.

[0014] The device in this embodiment utilizes the difference between the preset temperature and the actual detected temperature to first trigger a cooling operation, thereby enabling the refrigerator to perform normal temperature regulation. If the cooling operation is ineffective, it then checks whether the mode selection is correct, thus reducing unnecessary maintenance resource waste caused by directly reporting a fault after cooling failure. If the mode is incorrect, it reminds the user to quickly restore the refrigerator's function, shortening troubleshooting costs, reducing maintenance cycles, and minimizing the possibility of escalating problems caused by mode errors into product malfunctions, thereby improving user satisfaction and product trust.

[0015] In some embodiments of this application, the control device is specifically used for:

[0016] During the process of controlling the refrigeration system to cool down the storage room, the cooling time of the refrigeration system and the temperature detected by the first sensor during the cooling process are recorded.

[0017] If the cooling process takes a certain amount of time and the temperature detected by the first sensor does not meet the preset temperature condition, the cooling system is determined to have failed to cool down.

[0018] The device in this embodiment determines whether the cooling is normal by detecting the cooling situation, thereby determining whether automatic cooling alone can meet the user's needs. This enables automatic detection of faults, reduces the impact on the quality of stored items when the needs are not met for a long time, and improves user satisfaction.

[0019] In some embodiments of this application, the temperature detected by the first sensor includes a first temperature and at least two second temperatures. The first temperature is the temperature corresponding to a first duration, and the second temperature is the temperature collected at preset time intervals within the cooling process duration, wherein the preset time is less than the first duration. The preset temperature condition includes: the first temperature reaches the preset temperature; or, the first temperature does not reach the preset temperature, and the difference between the at least two second temperatures is less than or equal to the preset temperature difference.

[0020] Based on the above embodiments, the device in this embodiment further subdivides the cooling situation. When the preset temperature is not met, the recorded temperature difference is used to determine whether the cooling process actually exists, thereby reducing misjudgments caused by inaccurate determination of the detection time and improving the accuracy of the control method.

[0021] In some embodiments of this application, the refrigerator further includes a door, a cabinet, and a third sensor. The door is connected to the cabinet, and the third sensor is disposed on the door and / or the cabinet for detecting the open / closed state of the door. The control device is further configured to:

[0022] When the refrigerator displays a message indicating that it is in the first functional mode, monitor whether the door's open / closed state changes.

[0023] If the door's open / closed state changes but the refrigerator's function mode remains unchanged, the system continues to output a message indicating that the refrigerator is in its first function mode.

[0024] In this embodiment, after the user is notified that the refrigerator is in the first functional mode, the device resends the mode reminder by utilizing the door opening operation actively triggered by the user, in order to reduce the impact on the user experience caused by the user not knowing the current mode of the refrigerator. This ensures that the user can receive the prompt information about the refrigerator's current mode.

[0025] In some embodiments of this application, the control device is further configured to:

[0026] If the refrigerator meets the conditions for discarding the prompt message, discard the prompt message indicating that the refrigerator is in the first functional mode;

[0027] The discard conditions include at least one of the following:

[0028] The environment in which the refrigerator is currently located belongs to the environment type corresponding to the first functional mode; for example, the refrigerator has a camera, or can obtain its current location via Wi-Fi, or can have GPS to know its altitude, or even obtain some location information of the user through the APP that controls the refrigerator, etc.

[0029] Based on the prompt message indicating that the refrigerator is in the first functional mode, the user determines that the cumulative number of times the first functional mode has been used has reached a preset number; the user then disables the functional mode detection function.

[0030] The device setup in this embodiment utilizes the off reminder function to prevent the refrigerator from repeatedly issuing voice reminders during its display in the store, which would negatively impact the consumer's pre-purchase experience. Furthermore, since the store location is usually relatively fixed and the store environment differs significantly from the furniture environment, the refrigerator's environment type can be determined by acquiring the refrigerator's location. Based on the environment type and the notification status, it can then be determined whether to disable the function mode detection and reminder function, thereby reducing computational complexity and energy consumption during the detection process.

[0031] In some embodiments of this application, the refrigerator further includes a second sensor for acquiring environmental information about the refrigerator, the environmental information including location information; the control device is further configured to:

[0032] If the second sensor detects that there are no items in the storage room and the location information belongs to the preset location information, it is determined that the environment in which the refrigerator is currently located belongs to the environment type corresponding to the first functional mode.

[0033] The device in this embodiment uses a second sensor to automatically identify stored items, as well as the location and environment of the store. This allows for the screening of non-storage models in the store, enabling automatic shutdown reminders for these models. This reduces the disturbance to potential buyers and improves the user experience. Furthermore, when the refrigerator detects items in the storage compartment, it can promptly provide users with prompts indicating whether the function mode meets their storage needs. For example, a refrigerator storing goods for sale in the store cannot operate in the first function mode, thus reducing the possibility of stored items spoiling or becoming ineffective due to incorrect mode settings. This enhances the refrigerator's intelligence and improves user satisfaction.

[0034] In some embodiments of this application, the functional mode further includes a second mode, in which the refrigerator activates the first sensor, the interactive component, and the refrigeration system, among other electrically powered components; the control device is also used for:

[0035] In the event of a power outage and restart, retrieve the refrigerator's function mode before the power outage; enter the function mode before the power outage; and if the refrigerator was in the first function mode before the power outage, output a prompt message indicating that the refrigerator is in the first function mode.

[0036] The device configuration in this embodiment reduces the need for users to repeatedly set the refrigerator's functions by setting a breakpoint memory function. It also allows users to know the current functional mode of the refrigerator when it is powered on, increasing the user's control over the refrigerator's status and improving the user experience.

[0037] Secondly, embodiments of this application provide a method for controlling a refrigerator, the refrigerator comprising:

[0038] Storage room;

[0039] The first sensor is installed inside the storage room to detect the temperature inside the storage room;

[0040] A refrigeration system is used to lower the temperature of the storage room.

[0041] Interactive components are used to obtain the preset temperature set by the user for the refrigerator;

[0042] A control device is connected to the first sensor, the refrigeration system, and the interaction component respectively. The control device is used to control the refrigeration system to cool down the storage room when the temperature detected by the first sensor does not meet the preset temperature.

[0043] The method includes:

[0044] If the refrigeration system fails to cool down, determine whether the refrigerator is in the first functional mode;

[0045] When the refrigerator is in the first functional mode, a prompt message indicating that the refrigerator is in the first functional mode is output; in the first functional mode, the refrigerator does not start the refrigeration system.

[0046] This embodiment utilizes the difference between the preset temperature and the actual detected temperature to first trigger a cooling operation, thereby enabling the refrigerator to perform normal temperature regulation. If the cooling operation is ineffective, it then checks whether the mode selection is correct, thus reducing unnecessary maintenance resource waste caused by directly reporting a fault after cooling failure. If the mode is incorrect, it reminds the user to quickly restore the refrigerator's function, shortening troubleshooting costs, reducing maintenance cycles, and minimizing the possibility of escalating problems caused by mode errors into product malfunctions, thereby improving user satisfaction and product trust.

[0047] In some embodiments of this application, the method includes:

[0048] During the process of controlling the refrigeration system to cool down the storage room, the cooling time of the refrigeration system and the temperature detected by the first sensor during the cooling process are recorded.

[0049] If the cooling process takes a certain amount of time and the temperature detected by the first sensor does not meet the preset temperature condition, the cooling system is determined to have failed to cool down.

[0050] This embodiment determines whether the cooling is normal by detecting the cooling situation, thereby determining whether automatic cooling alone can meet the user's needs. This enables automatic detection of faults, reduces the impact on the quality of stored items when the needs are not met for a long time, and improves user satisfaction.

[0051] In some embodiments of this application, the temperature detected by the first sensor includes a first temperature and at least two second temperatures. The first temperature is the temperature corresponding to a first duration, and the second temperature is the temperature collected at preset time intervals within the cooling process duration, wherein the preset time is less than the first duration. The preset temperature condition includes: the first temperature reaches the preset temperature; or, the first temperature does not reach the preset temperature, and the difference between the at least two second temperatures is less than or equal to the preset temperature difference.

[0052] When the cooling process has lasted for a certain period of time, the first temperature is obtained.

[0053] If the first temperature does not meet the preset temperature, at least two second temperatures are obtained;

[0054] If the difference between at least two second temperatures does not meet the preset temperature difference, the cooling system is determined to have failed to cool down.

[0055] Based on the above embodiments, this embodiment further subdivides the cooling situation. When the preset temperature is not met, the recorded temperature difference is used to determine whether the cooling process actually exists, thereby reducing misjudgments caused by inaccurate determination of the detection time and improving the accuracy of the control method.

[0056] In some embodiments of this application, the refrigerator further includes a door, a cabinet, and a third sensor. The door is connected to the cabinet, and the third sensor is disposed on the door and / or the cabinet for detecting the open / closed state of the door. The method further includes:

[0057] When the refrigerator displays a message indicating that it is in the first functional mode, monitor whether the door's open / closed state changes.

[0058] If the door's open / closed state changes but the refrigerator's function mode remains unchanged, the system continues to output a message indicating that the refrigerator is in its first function mode.

[0059] In this embodiment, after the user is notified that the refrigerator is in the first functional mode, since the person who receives the notification may not be the same user who will use it later, in order to reduce the impact on the user experience due to the user not knowing the current mode of the refrigerator, the mode reminder is resent by the user actively triggering the door opening operation, so as to ensure that the user can receive the prompt information of the refrigerator mode.

[0060] In some embodiments of this application, the method further includes:

[0061] If the refrigerator meets the conditions for discarding the prompt message, discard the prompt message indicating that the refrigerator is in the first functional mode;

[0062] The discard conditions include at least one of the following:

[0063] The environment in which the refrigerator is currently located belongs to the environment type corresponding to the first functional mode; for example, the refrigerator has a camera, or can obtain its current location via Wi-Fi, or can have GPS to know its altitude, or even obtain some location information of the user through the APP that controls the refrigerator, etc.

[0064] The user determines that the cumulative number of times the first function mode has been used has reached a preset number based on the prompt message that the refrigerator is in the first function mode;

[0065] The user can disable the function mode detection feature.

[0066] In this embodiment, the method of turning off the reminder function is used to prevent the refrigerator from making multiple voice reminders when it is displayed in the store, which would affect the consumer's pre-purchase experience. Since the store location is usually relatively fixed and the store environment is very different from the furniture environment, the environment type of the refrigerator can be determined by obtaining the environment in which the refrigerator is located. Then, based on the environment type and the notification status, it is determined whether to turn off the function mode detection and reminder function, thereby reducing the computational complexity and energy consumption of the detection process.

[0067] In some embodiments of this application, the refrigerator further includes a second sensor for acquiring environmental information about the refrigerator, the environmental information including location information; the control device is further configured to:

[0068] If the second sensor detects that there are no items in the storage room and the location information belongs to the preset location information, it is determined that the environment in which the refrigerator is currently located belongs to the environment type corresponding to the first functional mode.

[0069] The device in this embodiment uses a second sensor to automatically identify stored items, as well as the location and environment of the store. This allows for the screening of non-storage models in the store, enabling automatic shutdown reminders for these models. This reduces the disturbance to potential buyers and improves the user experience. Furthermore, when the refrigerator detects items in the storage compartment, it can promptly provide users with prompts indicating whether the function mode meets their storage needs. For example, a refrigerator storing goods for sale in the store cannot operate in the first function mode, thus reducing the possibility of stored items spoiling or becoming ineffective due to incorrect mode settings. This enhances the refrigerator's intelligence and improves user satisfaction.

[0070] In some embodiments of this application, the functional mode further includes a second mode, in which the refrigerator activates the first sensor, the interaction component, and the refrigeration system; the method further includes:

[0071] In the event of a power outage and restart, retrieve the refrigerator's function mode before the power outage; enter the function mode before the power outage; if the refrigerator was in the first function mode before the power outage, output a prompt message indicating whether the refrigerator is in the first or second function mode.

[0072] This embodiment reduces the need for users to repeatedly set the refrigerator's functions by providing a breakpoint memory function. It also allows users to know the refrigerator's current functional mode status when it is powered on, increasing the user's control over the refrigerator's status and improving the user experience.

[0073] Thirdly, embodiments of this application provide a computer-readable storage medium storing computer-executable instructions, which, when executed by a processor, implement the aforementioned refrigerator control method.

[0074] The beneficial effects of the computer-readable storage medium provided in this embodiment can be found in the beneficial effects of the refrigerator control device and its various possible implementations, which will not be repeated here.

[0075] Fourthly, embodiments of this application provide a computer program product, including a computer program that, when executed by a processor, implements the above-described refrigerator control method.

[0076] The beneficial effects of the computer program product provided in this embodiment can be found in the beneficial effects of the refrigerator control device and its various possible implementations, which will not be elaborated here.

[0077] The refrigerator, refrigerator control method, storage medium, and program product provided in this embodiment control the refrigeration system to cool the storage compartment when the temperature detected by the first sensor does not meet the preset temperature. If the cooling process fails after cooling, the refrigerator's functional mode is determined. The functional mode includes a first functional mode, in which the refrigerator does not start the refrigeration system. When the refrigerator's functional mode is determined to be the first functional mode, a prompt message indicating that the refrigerator is in the first functional mode is output. Compared to existing technologies, this method utilizes the difference between the preset temperature and the actual detected temperature to trigger the cooling operation first, thereby achieving the refrigerator's normal temperature regulation function. If the cooling operation is ineffective, the correct mode selection is then determined, reducing unnecessary maintenance resource waste caused by directly reporting a fault after cooling failure. In the case of an incorrect mode, prompting the user allows for quick restoration of the refrigerator's function, shortening troubleshooting costs, reducing maintenance cycles, and minimizing the possibility of escalating a problem caused by a mode error into a product malfunction, thus improving user satisfaction and product trust.

[0089] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0090] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0091] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0092] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0093] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0094] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0095] In related technologies, refrigerators often utilize offline demonstrations to boost sales. During these demonstrations, to enhance the user experience, some of the refrigerator's functions are typically activated. For example, consumers might try touching interactive components to get a feel for the operation, or open the refrigerator door to see the interior. These experiences require the refrigerator to be powered on. However, if the cooling function is also activated after powering on, frequent activation leads to significant energy waste and severely reduces the lifespan of the cooling system, rendering the refrigerator unsellable and resulting in a serious waste of resources. Therefore, existing refrigerators typically have a "store mode." In this mode, the buttons, interactive components, lights, and other electrical parts operate normally, but the cooling system does not. This allows the refrigerator to remain usable by consumers even after becoming a display model.

[0096] Currently, refrigerators set to retail mode require manual switching to normal operating mode for proper cooling. However, after being sold to consumers, refrigerators on display are frequently forgotten to switch modes, or consumers may accidentally trigger retail mode without realizing it. Furthermore, consumers may not know how to switch back to normal cooling mode, leading to numerous complaints and a diminished user experience.

[0097] In view of this, the refrigerator provided in this application records the temperature change over a period of time when there is a cooling demand. If the temperature does not drop, it first checks the mode status. If the mode status is the store mode, it sends the mode status to the user, thereby reducing complaints about refrigerator quality problems caused by incorrect mode selection or accidental triggering of incorrect mode. This aims to solve the above-mentioned problems of the prior art.

[0098] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0099] First, it should be noted that in this embodiment, when the user faces the refrigerator door, the width direction of the refrigerator, i.e., the left-right direction, corresponds to the X-axis direction in the attached drawings; the depth direction of the refrigerator, i.e., the depth direction of the compartments, i.e., the front-back direction, corresponds to the Y-axis direction in the attached drawings; and the height direction of the refrigerator, i.e., the up-down direction, corresponds to the Z-axis direction in the attached drawings. The width of the refrigerator door is the dimension along the X-axis when the door is closed, the thickness of the door is the dimension along the Y-axis when the door is closed, and the height of the door is the dimension along the Z-axis.

[0100] Figure 1 This is a schematic diagram of the refrigerator in this embodiment. (Reference) Figure 1 As shown, the refrigerator of this embodiment includes a door 10 and a cabinet 20, wherein the cabinet 20 includes a storage compartment with a front opening for storing food and other items. The door 10 is installed on the front side of the storage compartment and is used to open or close the storage compartment.

[0101] There may be one storage compartment; or there may be multiple storage compartments, which may be arranged at intervals along the height and / or width of the refrigerator.

[0102] For example, storage rooms can be divided into freezer rooms, refrigerator rooms, and variable temperature rooms according to different storage temperatures.

[0103] For example, shelves can be installed in the storage room to increase the storage space for items.

[0104] For example, the storage room can also be equipped with drawers that can be pulled out relative to the depth of the refrigerator, making it convenient to classify, store, and retrieve items.

[0105] In some embodiments, the door 10 is rotatably mounted on the housing 20 to open or close the storage compartments. Exemplarily, the door 10 is rotatably connected to the housing 20 via a hinge assembly. When multiple storage compartments are provided, there may be one door 10, with multiple storage compartments sharing one door 10; alternatively, there may be multiple doors 10, each corresponding to a different storage compartment.

[0106] In some embodiments, the door 10 may also be slidably mounted on the housing 20 to open or close the storage compartment. For example, the door 10 is pull-outly connected to the housing 20 via a slide rail assembly. When multiple storage compartments are provided, multiple doors 10 may be provided, each corresponding to a different storage compartment.

[0107] Figure 2 This is a schematic diagram of the rear structure of the refrigerator in this embodiment; Figure 3 This is a schematic diagram of the refrigeration system in this embodiment. (Reference) Figure 2 , Figure 3As shown, a refrigeration system 30 is installed at the bottom rear of the refrigerator. The refrigeration system 30 includes a compressor 31, a fan 32, and a condenser 33. When the compressor 31 starts, the condenser 33 compresses the high-temperature medium along with the compressor 31 and releases the heat through the evaporator tube to obtain a cooled low-temperature medium. The low-temperature medium then enters the evaporator (internal structure of the cabinet, not shown in the figure) inside the cabinet 20, absorbs heat through the condenser tube, and exchanges heat with the items stored inside the cabinet 20. Finally, it circulates back to the condenser 33 to complete the refrigeration cycle.

[0108] In some embodiments, the refrigerator may also be equipped with an interactive component for interacting with a user or external devices. By touching the interactive component, the user can send operation requests, such as temperature setting requests or function mode selection requests, to the refrigerator's control device. The control device generates corresponding operation instructions based on the operation request and then sends these instructions to the corresponding actuators within the refrigerator to fulfill the user's operation request.

[0109] Figure 4 This is a schematic diagram illustrating the application scenario of the refrigerator in this application embodiment. (Refer to...) Figure 4 As shown, an interactive component 42 can be installed on the refrigerator 41. The interactive component 42 can be connected to the server 44 via the network 43, and the server 44 can be connected to the terminal device 45 via communication, thereby realizing the connection and control between the terminal device and the refrigerator 41. In addition, the interactive component 42 can also be directly connected to the terminal device 45 via communication.

[0110] For example, the interactive components may include: a touch display component, and / or function keys, and / or a voice acquisition component, and / or a communication component.

[0111] The control device generates corresponding operation instructions by acquiring the user's operation on the interactive components. These operation instructions may include selecting the refrigerator's function mode, such as turning on or off the store mode or the cooling mode.

[0112] For example, a touch display component may include a touch screen installed on a refrigerator.

[0113] In this implementation, the control device acquires the electrical signal generated after the user operates the touch screen, and determines the user's operation request based on the electrical signal, thereby generating an operation instruction that matches the operation request.

[0114] For example, function keys may include physical buttons located on the refrigerator or touch-sensitive virtual buttons.

[0115] In this implementation, the control device acquires the trigger signal generated after the user operates the physical button or the touch-sensitive virtual button, and generates the corresponding operation command based on the trigger signal.

[0116] It should be understood that there may be one or more physical buttons or touch-sensitive virtual buttons.

[0117] With only one function key, different operation commands can be generated by varying the number of times the single function key is pressed to meet different user operation requests. For example, pressing it once will switch between cooling mode and retail mode in a preset cycle. Another example is pressing it once within 3 seconds to activate cooling mode, and pressing it three times within 3 seconds to activate retail mode.

[0118] Alternatively, if there is only one function key, different operation commands can be generated by varying the duration of continuous triggering of a single function key to meet different user operation requests. For example, continuous touch for 1 second or less switches to cooling mode, while continuous press for 3 seconds or more switches to retail mode. Or, for example, continuous press for 3 seconds switches to cooling mode, while continuous press for 6 seconds or more switches to retail mode.

[0119] When multiple function keys are set, various corresponding operation commands can be generated through different combinations of these function keys to meet different user operation requests.

[0120] For example, the voice acquisition component may include a microphone positioned on the refrigerator.

[0121] Users can select different functions of the refrigerator via voice input. In this implementation, the control device acquires the electrical signal generated by the voice acquisition component due to the user's voice input and converts it into corresponding operation commands as the user's operation request.

[0122] For example, users can input the identifier of the sales mode or refrigeration mode by voice, thereby enabling the system to obtain the user's selected sales mode or refrigeration mode based on the user's voice input.

[0123] Alternatively, users can input the desired mode via voice, which will then be used to find the corresponding store mode or refrigeration mode, thus obtaining the selected store mode or refrigeration mode.

[0124] In some embodiments, the voice acquisition component can be controlled by associating it with function keys. Users can activate the voice acquisition component to perform voice acquisition by operating the function keys, or they can activate it via a voice command or a key associated with the voice acquisition component after operating the function keys.

[0125] For example, communication components may include Bluetooth modules, Wi-Fi modules, etc., installed on the refrigerator. These components enable the refrigerator to communicate with associated terminal devices, allowing users to send their selected store mode or cooling mode via these devices.

[0126] In practice, the terminal device can wirelessly connect to the refrigerator via a communication component to perform the aforementioned sending action. Alternatively, the refrigerator can connect to a network and a server via a communication component, allowing the terminal device to send the user's selected store mode or cooling mode to the refrigerator with the help of the server.

[0127] In this implementation, an app can be installed on the terminal device side for viewing and controlling the refrigerator, allowing users to perform control operations such as selecting the store mode or cooling mode through the app interface.

[0128] Optionally, the user can activate the communication component to establish a communication connection by operating the first function key, or in other words, enter a network state. Alternatively, the user can operate the first function key and then trigger the communication connection through a communication connection command or key press.

[0129] It should be understood that a refrigerator can have multiple communication components, and different communication components have different communication functions.

[0130] For example, it can have both Bluetooth and Wi-Fi modules. In this implementation, the user can select the desired communication component, or trigger the default communication component to establish a communication connection, or trigger the user's commonly used communication component to establish a communication connection, or have multiple communication components in operation until one of them receives the store mode or cooling mode sent by the user through the terminal device.

[0131] In addition to the interactive components mentioned above, the refrigerator can also be equipped with a variety of sensors, including a first sensor, a second sensor, and a third sensor.

[0132] It should be understood that the first sensor described above is used to detect the temperature inside the storage room, such as a temperature sensor. The second sensor described above is used to detect whether fresh or frozen items are present inside the storage room, such as a combination of at least two of a vision sensor, an infrared sensor, a temperature sensor, and a humidity sensor. The third sensor described above is used to detect the open / closed state of the door, such as a door open / closed status.

[0133] For example, by detecting the temperature inside the storage compartment using the first sensor, the temperature change inside the storage compartment can be obtained, thereby determining whether the refrigerator is currently in a cooling or non-cooling state. This is then matched with the selected function mode to help determine whether the refrigerator is malfunctioning and to send corresponding prompts to the user.

[0134] By detecting the items stored in the storage room through the second sensor, the user's usage needs can be indirectly obtained. This allows the system to determine whether the current functional mode meets the user's needs and to promptly remind the user to switch functional modes if not.

[0135] For example, a vision sensor can capture images of items stored in a storage room. After the control device preprocesses the captured images, it sends them to a preset image processing model to identify whether the items need to be refrigerated or frozen. The preset image processing model is an image recognition model that has been trained. It can determine the name of the identified item based on the classification probability of the identified item. The name of the item can be preset with a corresponding suitable storage temperature range. Then, by detecting the actual temperature through a temperature sensor, it is determined whether the currently detected temperature of the storage room meets the suitable storage temperature range. If it does, no processing is performed. If it does not meet the range, it is necessary to find out whether the reason for the non-compliance is a specific reason such as a functional mode or a device malfunction.

[0136] Optionally, the third sensor mentioned above includes a door switch. Multiple door switches can be provided, and the multiple door switches are diagonally distributed along the shape of the door body 10 to more accurately determine whether the door body 10 is in contact with and closed with the box body 20.

[0137] Figure 5 This is a schematic diagram showing the location of the door switch in this embodiment. (Reference) Figure 5 As shown, the door switches are columnar switches, and there are four of them, including the first switch 51, the second switch 52, the third switch 53 and the fourth switch 54. The four door switches are respectively located at the four corners of the refrigerator.

[0138] In some embodiments, the door switches at the four corners are connected in series. The opening and closing action of the door 10 is obtained by pressing the column switch on the door 10. When any of the four corner switches in the circuit detects that the door is not closed, it will be identified as the door 10 is not closed properly, and the relevant signal of the detected door 10 not being closed will be sent to the control device.

[0139] Optionally, the door switches at the four corners may not be connected to each other, but they are all connected to the control device. The door 10 presses the column switch to obtain the opening and closing action of the door 10. Since the door switches are connected to the control device respectively, when any of the four corner switches detects that the door is not closed, the control device can identify that the door 10 at the corresponding position is not closed according to the signal sent by the door switch.

[0140] In some embodiments, the refrigerator may also include a storage component, with both the control device and the storage component located inside the refrigerator.

[0141] Alternatively, the storage component can be integrated with the control device, or it can be a separate component from the control device.

[0142] Storage components are used to store data; for example, various software control programs, some modes and / or parameters of terminal devices, etc.

[0143] Specifically, the program may include program code, which includes computer operation instructions.

[0144] The control device may include, for example, one or more circuits or chips with control functions.

[0145] A control device is used to control the operation of the refrigerator and respond to user operations through various software control programs stored in memory.

[0146] The executing entity in this application embodiment can be a control device in the refrigerator or a server corresponding to the refrigerator. The server is located in the cloud, connected to the refrigerator via a network, and issues control commands to the refrigerator, or forwards control commands sent by the user through a terminal device to the refrigerator, etc.

[0147] The following uses a control device in a refrigerator as an example to illustrate the technical solution of this application and how it solves the aforementioned technical problems. The following specific embodiments can be combined with each other, and similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0148] Figure 6 A flowchart illustrating a refrigerator control method provided in this application. Figure 1 .like Figure 6 As shown, the method includes the following steps:

[0149] S61. In the event that the refrigeration system fails to cool down, determine whether the refrigerator is in the first functional mode.

[0150] The functional modes include a first functional mode, in which the refrigerator activates the first sensor and the interaction component, but does not activate the refrigeration system.

[0151] For example, the first functional mode is the store mode. When the refrigerator is in the store mode, the control device, the interaction component and the first sensor are all operating normally, while the refrigeration system is in a closed state. The control device will not start the refrigeration system due to changes in the parameters of the interaction component and the first sensor, thereby reducing the usage time of the refrigeration system, extending the service life of the refrigeration system, and will not affect the normal experience of users of the refrigerator prototype in the store environment for functions other than the refrigeration effect.

[0152] S62. When the refrigerator is in the first functional mode, output a prompt message indicating that the refrigerator is in the first functional mode.

[0153] For example, since the first functional mode is a special non-cooling mode, users who purchase the refrigerator demo unit need to use the refrigerator's cooling function during normal use. Therefore, when the preset temperature cannot be reached, it is necessary to show the user a functional mode reminder that the refrigerator cannot reach the preset temperature because it is in a special mode. This will prevent users from mistakenly believing that the refrigerator has a quality problem because it cannot reach the temperature setting, thereby reducing the number of complaints caused by incorrect functional mode settings.

[0154] The above control method utilizes the difference between the preset temperature and the actual detected temperature to first trigger the cooling operation, thereby realizing the refrigerator's normal temperature regulation function. If the cooling operation is still ineffective, it first checks whether the mode selection is correct, thereby reducing unnecessary maintenance resource waste caused by directly reporting a fault after cooling failure. If the mode is incorrect, it reminds the user to quickly restore the refrigerator's function, shortening the fault-solving cost, reducing the maintenance cycle, and reducing the possibility of escalating problems caused by mode errors into product failures, thus improving user satisfaction and product trust.

[0155] Figure 7 A flowchart illustrating a refrigerator control method provided in this application. Figure 2 .like Figure 7 As shown, the method includes the following steps:

[0156] S71. During the process of controlling the refrigeration system to cool down the storage room, record the cooling process duration of the refrigeration system and the temperature detected by the first sensor during the cooling process.

[0157] For example, when the temperature detected by the first sensor is higher than a preset temperature, the control device will control the cooling system to cool down the storage compartment. By recording the temperature detected by the first sensor from the start of controlling the cooling system to lower the temperature, it is possible to determine when the cooling operation is complete.

[0158] S72. If the cooling process takes a first duration and the temperature detected by the first sensor does not meet the preset temperature condition, the cooling system is determined to have failed to cool down.

[0159] The preset temperature conditions include: the first temperature reaches the preset temperature; or, the first temperature does not reach the preset temperature, and the difference between the at least two second temperatures is less than or equal to the preset temperature difference.

[0160] The temperature detected by the first sensor includes a first temperature and at least two second temperatures. The first temperature is the temperature corresponding to a first duration, and the second temperature is the temperature collected at preset time intervals within the first duration, wherein the preset time is less than the first duration.

[0161] For example, in the second normal cooling mode, the cooling system is in the start state, and the control device can normally control the cooling system to perform cooling operations. At this time, it can determine when to stop the cooling process based on whether the detected temperature in the storage room has reached the preset temperature.

[0162] However, in the non-cooling first function mode, the refrigeration system is off, and the refrigeration control of the control device is ineffective. Since cooling cannot be unlimited, a first duration is set to determine whether the first temperature inside the storage room meets the preset temperature requirement within that first duration. The first duration is the time required for the refrigeration system to reach a second temperature threshold from a first temperature threshold under normal operating conditions, and the first temperature threshold is greater than the second temperature threshold.

[0163] For example, since the first temperature is the temperature obtained when the first duration is reached, the temperature may have changed by decreasing before the first duration. If the temperature decreases to a certain extent, even if it has not reached the preset temperature decrease range, it can still prove that the refrigeration system has achieved refrigeration, that is, it is not in the first functional mode of not refrigerating at all. Therefore, it is necessary to obtain at least two second temperatures before the first duration in order to calculate the temperature difference using multiple temperatures and obtain the temperature change.

[0164] For example, since the temperature inside the storage compartment changes with the ambient temperature when the refrigerator's refrigeration system is not working, the temperature may also change before the first duration in the first functional mode. However, the change in ambient temperature is usually small. Therefore, a preset temperature difference is set to filter the difference in the second temperature to ensure that the cooling process is dominated by the refrigerator's refrigeration system.

[0165] S73. If the refrigeration system fails to cool down after the cooling process, obtain the refrigerator's functional mode.

[0166] The functional modes include a first functional mode, in which the refrigerator activates the first sensor and the interaction component, but does not activate the refrigeration system.

[0167] For example, after determining through the above steps that the reason for the cooling failure of the refrigeration system is that the refrigeration system has not started or is not working, rather than that the refrigeration system is not cooling enough, since the refrigeration system is in a normal non-starting state in the first functional mode, the function mode of the refrigerator can be obtained first to determine whether the reason is the first functional mode. If it is not the first functional mode, an alarm prompt that there may be a refrigeration failure can be output.

[0168] S74. If the refrigerator's function mode is determined to be the first function mode, output a prompt message indicating that the refrigerator is in the first function mode.

[0169] The specific implementation of S74 is similar to that of S62 in the above embodiment, and will not be described again here.

[0170] Figure 8 A flowchart illustrating a refrigerator control method provided in this application. Figure 3 .like Figure 8 As shown, based on the above control method, this method includes the following steps:

[0171] S81. When the refrigerator is in the first functional mode, monitor whether the door opening / closing status changes.

[0172] For example, the door's open / closed state includes both open and closed states. In the first functional mode, the cooling system is not working, and opening and closing the door will not affect the temperature changes inside the storage room. However, the prompts for the first functional mode may be obscured by other information or go unnoticed by the user. Since the open state of the door has a significant impact on the cooling system after it starts up, it needs to be monitored.

[0173] S82. If the opening / closing state of the door changes and the function mode of the refrigerator does not change, continue to output a prompt message indicating that the refrigerator is in the first function mode.

[0174] For example, when the door's open / closed state changes to open, it indicates that a user is operating the refrigerator, meaning the user is within the range of the refrigerator's notification information. In this case, it is easier for the user to receive the notification information.

[0175] The output terminal for providing prompts is determined based on the type of prompt. For example, when the prompt is a voice reminder, the user terminal can be the refrigerator's player or a third-party player connected to the refrigerator; or, when the prompt is text, the user terminal can be the refrigerator's display screen or a third-party display screen connected to the refrigerator; or, when the prompt is light, the user terminal can be the refrigerator's indicator light, which indicates that the refrigerator is currently in its first functional mode.

[0176] Optionally, when the refrigerator is in a first functional mode and the first functional mode that is turned off is the voice reminder function, the number of times the door is opened and closed is obtained.

[0177] For example, the number of times the door is opened and closed here refers to completing one cycle from closing to opening. Since voice prompts can be quite disruptive to users, if the door is opened and closed frequently, each prompt will create noise pollution and negatively impact the user experience. Therefore, the voice prompt function can be disabled.

[0178] Since the refrigerator does not start the cooling system in the first function mode, the first function mode is a special mode that the refrigerator does not use often and requires special attention from the user. After the voice reminder of the first function mode is turned off for a period of time, the user may forget the mode that the refrigerator is in, or the special mode that the refrigerator is in may not be known by other users. Therefore, it is necessary to set a function to automatically restore it after it has been turned off for a period of time.

[0179] Similar to the steps above, when the door's open / closed state changes, it indicates that a user is operating the refrigerator. When the number of changes reaches a certain threshold, the likelihood of the user changing increases, thus triggering a new reminder.

[0180] If the number of times the door is opened and closed meets the preset threshold, the voice reminder function of the first function mode is restarted.

[0181] For example, restarting the voice reminder method allows the user who has changed the method to more directly obtain the current function mode of the refrigerator.

[0182] In some embodiments, the prompt message can be turned off in several ways, that is, when the refrigerator meets the conditions for discarding the prompt message, the prompt message indicating that the refrigerator is in the first functional mode is discarded; for example:

[0183] The discard conditions include at least one of the following:

[0184] Condition 1: The environment in which the refrigerator is currently located belongs to the environment type corresponding to the first functional mode.

[0185] The refrigerator also includes a second sensor for acquiring environmental information, including location information. When the second sensor detects that there are no items in the storage compartment and the location information is a preset location, it is determined that the environment in which the refrigerator is currently located belongs to the environment type corresponding to the first functional mode.

[0186] For example, the second sensor includes a visual sensor such as a camera. The camera can acquire images of the storage room, and the presence of items in the storage room can be determined based on image analysis.

[0187] The second sensor may also include a positioning sensor, such as a precise positioning device like Wi-Fi or GPS, to obtain the location information of the refrigerator, such as the store address and floor information corresponding to the geographic coordinates. This information is then combined with a visual sensor such as a camera to obtain images of the environment around the refrigerator. Based on the image analysis, the environmental information of the refrigerator is obtained, thereby determining whether the current environment of the refrigerator meets the environmental type corresponding to the first functional mode.

[0188] Condition 2: The user determines that the cumulative number of times the first function mode has been used has reached a preset number based on the prompt information that the refrigerator is in the first function mode.

[0189] For example, in an unattended store, it would waste energy if the first function mode remained in the prompt state for a long time. Therefore, the reminder can be automatically turned off after the preset number of prompts. Since consumers will turn off the device after purchasing the demo unit for transportation, the function mode reminder will be triggered again after the device is turned off and restarted. Therefore, there is no need to worry that the automatic shutdown will affect the consumer's user experience.

[0190] Condition 3: The user has turned off the function mode detection function, that is, the function has been manually turned off.

[0191] In some embodiments, Figure 9 A flowchart illustrating a refrigerator control method provided in this application. Figure 4 .like Figure 9 As shown, the method includes the following steps:

[0192] S91. In the event of a power outage and restart of the refrigerator, obtain and enter the function mode before the power outage.

[0193] For example, setting a power outage memory function can reduce the tedious operation of resetting for users and improve the user experience.

[0194] S92. If the refrigerator was in the first functional mode before the power was cut off, output a prompt message indicating that the refrigerator is in the first functional mode.

[0195] For example, since a power outage and restart may occur when a demo unit is moved from the store to the user's location, and the first functional mode used in the store has a significant impact on the user's normal use, it is necessary to emphasize the reminder to inform the user of the refrigerator's current functional mode. This would reduce user dissatisfaction with the refrigerator's cooling function caused by using the first functional mode, and thus reduce after-sales service reports caused by mode setting issues.

[0196] Optionally, Figure 10 A flowchart illustrating a refrigerator control method provided in this application. Figure 5 .like Figure 10As shown, the method includes the following steps:

[0197] S101. When the second sensor detects that there are fresh or frozen items in the storage room, the refrigerator's functional mode is obtained.

[0198] For example, by detecting the items stored in the storage room through the second sensor, the user's usage needs can be indirectly obtained, and then it can be determined whether the current functional mode meets the user's usage needs, and if not, the user can be promptly reminded to switch functional modes.

[0199] The second sensor can be a vision sensor that can collect images of items stored in the storage room. After the control device preprocesses the collected images, it sends them to a preset image processing model to identify whether the items need to be refrigerated or frozen. The preset image processing model is an image recognition model that has been trained. It can determine the name of the identified items based on the classification probability of the identified items. The name of the items can be preset with a corresponding suitable storage temperature range, such as refrigeration temperature range, freezing temperature range, or room temperature temperature range.

[0200] It should be understood that fresh or frozen items need to be stored within a very wide temperature range. When such items are placed in the storage room, it indicates that the user needs to use the refrigerator's cooling function, which requires the refrigerator's cooling system to be activated. However, the cooling system is not activated in the first function mode. Therefore, after the items are identified, it is necessary to first confirm whether the refrigerator's current function mode is correct.

[0201] S102. If the refrigerator is in the first functional mode, output a prompt message indicating that the refrigerator is in the first functional mode again.

[0202] For example, in the first functional mode, the control device cannot control the refrigeration system to achieve refrigeration, and thus cannot guarantee the storage time of items in the storage room. Therefore, it is necessary to notify the user of the current functional mode status in a timely manner so that the user can switch the functional mode according to actual needs and reduce the damage to stored items caused by incorrect mode settings.

[0203] The time point at which the prompt message indicating that the refrigerator is in the first functional mode is output again is at the time when the user places the item, to ensure that the user can receive the corresponding notification information.

[0204] Optionally, after receiving the notification of the function mode, users can choose to switch modes according to their actual needs, or they can choose not to switch, without needing to set up the automatic mode switching function. For example, temporarily storing or displaying food in a refrigerator demo unit in a store environment.

[0205] It should be understood that in the above embodiments, the prompt information can exist in a variety of forms, including at least one of the following prompt methods: using a player installed on the refrigerator to provide voice broadcast prompts, or using a display screen installed on the refrigerator to provide text display prompts, or using a function warning light installed on the refrigerator to provide light prompts, or using a third-party terminal, such as a speaker, monitoring or other intelligent third-party terminal device that is in the same working environment as the refrigerator and is associated with it.

[0206] This application also provides a computer-readable storage medium, which may include various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk. Specifically, the computer-readable storage medium stores program instructions, which are used in the methods described in the above embodiments.

[0207] This application also provides a computer program product including executable instructions stored in a readable storage medium. At least one control module of the refrigerator can read the executable instructions from the readable storage medium, and the at least one control module executes the executable instructions to cause the refrigerator to perform the methods provided in the various embodiments described above.
