[0017] 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 the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0020] Refrigerators are ubiquitous devices for refrigerating food and medicine. Energy efficiency has become a key focus for both the refrigerator industry and consumers. Current technologies primarily address energy conservation in refrigerators by improving compressor efficiency, optimizing insulation materials, and refining the refrigeration cycle. However, the use of refrigerators also presents challenges to their energy efficiency. Refrigerators are frequently used devices, requiring the door to be opened often. When the door is open, the refrigerator compartment is connected to the external environment, leading to heat exchange and disturbance of the internal heat. When the refrigeration module operates at high energy consumption, it needs to adjust its operating parameters to restore the disturbed compartment environment to its set state. This results in the refrigeration module operating at high energy consumption to cope with the heat disturbance, further increasing the refrigerator's energy consumption.

[0021] Therefore, while focusing on achieving optimal compressor efficiency, insulation, and refrigeration cycle performance, refrigerators also need to pay closer attention to the adverse effects of user behavior on energy consumption. To this end, this application proposes a real-time refrigerator door opening prompt method to provide users with door opening suggestions, balancing user behavior with refrigerator energy consumption.

[0022] In the following embodiments, opening the door is interpreted broadly: that is, the internal compartments of the refrigerator are in a state of communication with the outside world; for example, in some refrigerator structures, the refrigerator compartment is constructed as a drawer structure, and opening the drawer can be understood as opening the door (such as a French door structure).

[0023] Before demonstrating the steps for the door opening indicator, let's explain the refrigerator's refrigeration module. The refrigeration module provides cooling to the compartments. It mainly includes a compressor, condenser, throttling device, and evaporator. The compressor is the heart of the refrigerant cycle; it compresses the refrigerant and supplies it to the condenser. The condenser cools the refrigerant and then supplies it to the throttling device. The throttling device reduces the pressure of the refrigerant, resulting in a low-temperature, low-pressure liquid refrigerant. This liquid refrigerant enters the evaporator, where it dissipates heat and absorbs heat from the air, producing cool air. This cool air, driven by a fan, enters the compartments. Alternatively, the liquid refrigerant can enter the evaporator, dissipate heat, and the cool air is transferred to the compartment walls. The refrigerant, having absorbed heat, re-enters the compressor, completing one refrigeration cycle.

[0024] The refrigerator also includes a controller for controlling the refrigerator to perform cooling. The controller is also used to perform the steps in the door opening prompt method provided in the embodiments of this application.

[0025] The refrigerator may also have a notification module or be connected to a notification module. For example, the notification module could be an indicator light or display screen on the refrigerator door. Alternatively, the notification module could be connected to a user terminal, such as a mobile phone, linked to the refrigerator.

[0026] Based on the above description of the embodiments, this application provides a refrigerator and its door opening prompt method, control device and computer-readable storage medium, which will be described in detail below.

[0027] like Figure 1 The diagram shown is a flowchart of an embodiment of the refrigerator door opening prompt method in this application. The door opening prompt method includes: S100, retrieve the current time period; S200, obtain the operating status of the cooling module; S300, based on the current time period and the operating status, generate a prompt message; the prompt message is used to suggest to the user whether to open the refrigerator door; S400, the prompt information is displayed on the prompt module.

[0028] In the technical solution of this application embodiment, a prompt message is generated based on the current time period and the operating status of the refrigeration module, and the prompt message is displayed on the prompt module. This prompt message is displayed in a prominent manner to suggest to the user whether it is possible to open the refrigerator door at the current time period. This reduces the occurrence of users opening the door unnecessarily, which would increase the energy consumption of the refrigeration module. This effectively guides users to form energy-saving habits and balances the relationship between users' usage habits and the energy efficiency of the refrigerator.

[0029] In this embodiment, the refrigerator's interior divides a 24-hour day into several distinct time periods, such as 7-9 AM, 11 AM-1 PM, and 5-7 PM, which are the user's usual usage periods; the remaining time periods are the user's non-usual usage periods. For example, if the current time is 3 PM, then the current time period is the user's non-usual usage period. In this embodiment, the refrigeration module has high-frequency operation, medium-frequency operation, low-frequency operation, and a stopped operation state. The high-frequency operation state is when the refrigerator is in a high-energy-consumption phase. Therefore, based on the current time period and the refrigeration module's operating state, a suggestion is given regarding whether the refrigerator door can be opened, to avoid users opening the door unnecessarily and increasing the refrigeration module's energy consumption.

[0030] As an optional implementation of the above embodiments, Figure 2 As shown, generating the prompt information based on the current time period and the operating status includes: S310, determine whether the current time period is a time period when the user does not usually use the device; S320, determine whether the operating state of the cooling module is a high-frequency operating state; S330, if the current time period is a period when the user is not accustomed to using the refrigerator and the refrigeration module is in a high-frequency operating state, a first prompt message is generated; the first prompt message is used to suggest that the user postpone opening the refrigerator door; Displaying the prompt information on the prompt module includes: S410, the first prompt message is displayed on the prompt module.

[0031] Reference Figure 2 As shown, when the current time period is a time when the user is not accustomed to using the refrigerator and the refrigeration module is operating at high frequency, the refrigerator is in a high-energy-consumption mode during this period. Since this is not a time when the user typically uses the refrigerator, a first prompt message is generated on the prompt module, advising the user to postpone opening the refrigerator door. This is because this is not a time when the user usually opens the refrigerator door, and the refrigerator is operating in a high-energy-consumption mode; opening the door at this time would result in even higher energy consumption.

[0032] As an optional implementation of the above embodiments, Figure 3 As shown, generating the prompt information based on the current time period and the operating status includes: S340, if the refrigeration module is not in the high-frequency operating state, a second prompt message is generated; the second prompt message is used to remind the user that the refrigerator door can be opened at any time; Displaying the prompt information on the prompt module includes: S420, a second prompt message is displayed on the prompt module.

[0033] In this embodiment, if the refrigeration module is not in a high-frequency operating state, opening the door at any time will not have a significant impact on the refrigerator's energy consumption. In this case, a second prompt message is generated and displayed on the prompt module.

[0034] In some embodiments, the second prompt message can be divided into two categories. Taking an indicator light as an example, the first category is as follows: If the cooling module is not in the high-frequency operating state and the current time period is during the user's usual usage period, the second prompt message can be that the indicator light is constantly on blue or off, that is, prompting the user that the cooling module is currently in a low-power state during the user's usual usage period. The second category is as follows: If the cooling module is not in the high-frequency operating state and the current time period is during the user's unused usage period, the indicator light can be displayed as green.

[0035] As an optional implementation of the above embodiments, Figure 4 As shown, the door opening prompt method further includes: If the current time period is a period when the user is not accustomed to using the device and the cooling module is in a high-frequency operating state, then after generating the first prompt message; S510, obtain the real-time status of the door or the real-time operating status of the refrigeration module; S520, if the real-time status of the door is switched to the open state or the real-time operating status of the cooling module is switched to the non-high frequency operating state, then the prompt module is controlled to exit the state of displaying the first prompt information.

[0036] In this embodiment, after prompting the user to postpone opening the door, the real-time status of the door or the real-time operating status of the refrigeration module is monitored. It should be noted that prompting the user to postpone opening the door does not force the user not to open it. The door may still be opened at this time. If the user opens the door after receiving the first prompt from the prompt module, the prompt module will exit the state of displaying the first prompt; that is, if the suggestion to not open the door is invalid, the prompt is ineffective. If the user needs to take items out of the refrigerator or place items in the refrigerator, the first prompt can be removed, and no prompt is needed in this case.

[0037] In one embodiment, if the refrigeration module switches from a high-frequency operating state to a low-frequency operating state, it indicates that the refrigerator has entered a low-power consumption phase. At this time, the prompting module is controlled to exit the state of displaying the first prompting information so as not to prompt the user to postpone opening the door. In some embodiments, the prompting module may subsequently switch to displaying a second prompting information.

[0038] In some embodiments, once the refrigerator has exited the user's usual usage period, the notification module can be controlled to exit the state of displaying the first notification information. Even if the user opens the door immediately, the impact on the refrigerator's power consumption is minimal.

[0039] As an optional implementation of the above embodiments, determining whether the current time period is a period when the user is not accustomed to using the device includes: Obtain the user's historical door opening times; Based on the historical door opening times, determine the user's non-habitual usage periods; Determining whether the operating state of the cooling module is in a high-frequency operating state based on whether the current time period is within the non-habitual usage period; and / or, including: Obtain the operating parameters of the refrigeration module; Based on the operating parameters, determine whether the operating state of the refrigeration module is a high-frequency operating state.

[0040] In this embodiment, by analyzing historical door opening times, users' uncommon usage periods can be determined. For example, the refrigerator in this application is equipped with a habit learning module to receive signals from a door status recognition unit (such as a micro-motion sensor), record and analyze historical door opening times, and establish a high-frequency usage period model for users through clustering algorithms and time segmentation statistics to determine users' uncommon and common usage periods. Alternatively, based on historical door opening times, the distribution of current door opening times can be determined, and users' uncommon usage periods can be statistically analyzed. For instance, if historical door opening times are concentrated between 7-8 am, 11-12 pm, and 5-7 pm, then users' common usage periods are 7-8 am, 11-12 pm, and 5-7 pm, and the remaining time periods are users' uncommon usage periods.

[0041] In this embodiment, by acquiring the operating parameters of the refrigeration module, it can be determined whether the refrigeration module is operating at a high frequency. For example, by acquiring the compressor's operating current / voltage, the compressor's operating power can be determined; when the operating power exceeds a preset threshold, the refrigeration module is determined to be operating at a high frequency; and when the operating power is below the preset threshold, the refrigeration module is determined not to be operating at a high frequency. Alternatively, the compressor's rotational speed can be acquired; if the speed exceeds a preset speed, the refrigeration module is determined to be operating at a high frequency; and if the speed is below the preset speed, the refrigeration module is determined not to be operating at a high frequency. Furthermore, the compressor's frequency can be acquired; if the frequency is higher than a preset frequency, the refrigeration module is determined to be operating at a high frequency; and if the frequency is lower than the preset frequency, the refrigeration module is determined not to be operating at a high frequency.

[0042] As an optional implementation of the above embodiments, generating prompt information based on the current time period and the operating state includes: when it is determined that the refrigeration module is in the high-frequency operating state, controlling the refrigerator to enter the candidate prompt state, and then determining whether the current time period is a time period when the user does not usually use the refrigerator; if so, generating the first prompt information.

[0043] In this embodiment, the system determines whether the current time period is a period when the cooling module is operating at a high frequency. This avoids wasting system computing resources by frequently determining whether the current time period is a period when the user is not used to using the system, thus saving the computing resources inside the controller and reducing power consumption.

[0044] In some embodiments, the system only begins determining whether the current time period is a period of infrequent user use when the cooling module enters a high-frequency operating state. If the current time is not a period of infrequent user use, then the current time period is not a period of infrequent user use. At this time, the system determines whether the prompt module should switch to displaying the first prompt message based on the time information fed back by the timer. For example, if the cooling module enters a high-frequency operating state at 5:30, and the current time is not a period of infrequent user use, then the prompt module displays the second prompt message. When the timer reaches 7:00, the prompt module displays the first prompt message. Furthermore, if the cooling module enters a high-frequency operating state, but switches to a low-frequency operating state before the time enters a period of infrequent user use, the system either does not acquire time information or the acquired time information is not used to control the prompt module to switch display information.

[0045] As an optional implementation of the above embodiments, the user's uncommon usage period includes a first period and a second period; during the first period, the user's historical frequency of opening the refrigerator door is the first frequency; during the second period, the user's historical frequency of opening the refrigerator door is the second frequency; the first frequency is greater than the second frequency. In this embodiment, the user's uncommon usage period includes a first period and a second period. During the first period, the user's historical frequency of opening the refrigerator door is higher than the user's historical frequency of opening the refrigerator door during the second period.

[0046] The first prompt message includes a prompt message with a third frequency and a prompt message with a fourth frequency; the third frequency is less than the fourth frequency.

[0047] If the current time period is a period when the user is not accustomed to using the refrigerator and the refrigeration module is in a high-frequency operation state, a first prompt message is generated; the first prompt message is used to suggest that the user postpone opening the refrigerator door, including: If the current time period is the first time period and the cooling module is in a high-frequency operating state, a prompt message with a fourth frequency is generated; If the current time period is the second time period and the cooling module is in a high-frequency operating state, a prompt message with a third frequency is generated.

[0048] In this embodiment, if the current time period is either the first time period or the second time period and the cooling module is operating at high frequency, the prompting module needs to display a first prompt message. When the current time period is the first time period, because the user has a higher historical frequency of opening the door during the first time period, the user is more likely to open the door, therefore the first prompt message is displayed more frequently to provide a more prominent reminder to the user and reduce the likelihood of them opening the door. When the current time period is the second time period, because the user has a lower historical frequency of opening the door during the second time period, the user is less likely to open the door, therefore the first prompt message is displayed less frequently to provide a less prominent reminder to the user.

[0049] For example, consider LED lights. A fourth frequency alert is indicated by an amber light with a first flashing frequency, and a third frequency alert is indicated by an amber light with a second flashing frequency. The first flashing frequency is higher than the second. That is, during off-peak usage periods, the cooling module operates at a higher frequency. During the first period, users are more likely to open the door, hence the higher LED flashing frequency provides a more noticeable alert; during the second period, users are less likely to open the door, hence the lower LED flashing frequency provides a less noticeable alert. For instance, 3-4 PM and 2-3 AM are off-peak usage periods; and users open the door more frequently during 3-4 PM compared to 2-3 AM. When the cooling module operates at a high frequency during 2-3 AM, the LED flashes amber once every 2 seconds; when the cooling module operates at a high frequency during 3-4 PM, the LED flashes amber once every 1 second.

[0050] like Figure 5 This application provides an example of the system architecture for a refrigerator door opening prompt method according to an embodiment of the present application. A data acquisition module includes a power monitoring unit for real-time monitoring of compressor power or operating frequency, and a door status sensor for detecting the door's open / closed state. A data processing and control module, serving as the core controller, integrates a status recognition unit to receive signals from the power monitoring unit and, by determining the threshold range of the power value, identifies the compressor status as stopped, operating at low frequency, or operating at high frequency. A habit learning unit receives signals from the door status sensor, records and analyzes historical door opening data, and establishes a model of the user's high-frequency usage periods through clustering algorithms and time-segmented statistics. For example, it identifies three peak meal times: morning, noon, and evening. A human-machine interaction module includes a visual prompt device located on the exterior of the refrigerator, such as the front or side panel of the door, for example, a multi-color LED indicator light integrated into the refrigerator's external control display panel.

[0051] like Figure 6An example of a refrigerator is shown. The refrigerator is equipped with LED lights. When the LED light is red, it indicates a potential malfunction. When the LED light is solid green, it means the compressor is off or operating at a low frequency, and the door can be opened at any time. When the LED light is solid blue, it means the compressor is operating at a lower frequency, but during the user's usual usage period. When the LED light is flashing amber, it means the compressor is operating at a higher frequency, during a period not the user's usual usage period, and the user is advised to open the door later.

[0052] The technical solution of this application can solve the problem of unnecessary energy consumption caused by user door opening and closing behavior, so that the refrigerator can effectively guide the user's main behavior of cold energy loss by opening and closing the door, and effectively avoid the user forcing the refrigeration system to deal with the heat load in a high-energy-consumption mode at an inappropriate time, resulting in additional energy waste.

[0053] Furthermore, existing refrigerator alert functions are limited to passive warnings, such as alarms for exceeding the door open time limit. They cannot proactively and intelligently provide users with forward-looking energy-saving suggestions from the perspective of optimizing overall system energy efficiency, resulting in a poor user experience and limited energy-saving effects. This application, however, combines the refrigerator's operating status and the current time period to proactively and intelligently provide users with forward-looking energy-saving suggestions, thereby improving the user experience.

[0054] Furthermore, existing technologies suffer from a mismatch between door-opening prompts and actual user needs. For instance, simple prompt systems may interfere during peak refrigerator usage periods, such as when users are cooking. This type of prompt not only fails to effectively save energy but also negatively impacts the user experience, causing users to disable the prompt function and rendering the energy-saving design ineffective. However, during peak usage periods, when users are accustomed to using the refrigerator, it is more effective to avoid prompts suggesting not to open the door, thus meeting the user's actual needs and balancing door opening with energy conservation.

[0055] The technical solution of this application can intelligently prompt the door to open. It can intelligently identify the real-time energy consumption status of the refrigerator and, in combination with the user's usage habits, provide the user with the optimal door opening suggestion in a non-intrusive manner, thereby guiding the user to form energy-saving habits and reducing the overall operating energy consumption of the refrigerator.

[0056] To better implement the door opening prompt method in the embodiments of this application, based on the door opening prompt method, the embodiments of this application also provide a refrigerator control device, such as...
