[0048] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of this application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0050] In related technologies, the nominal noise level of refrigerators is the result of testing in a standard laboratory according to standards. However, due to different usage environments, the noise perception of the same refrigerator can often vary. Furthermore, test data shows that the main noise sources of refrigerators come from the compressor and fan motor. These noise levels vary at different speeds, especially at high speeds, which can affect the user experience. High speeds are typically required to ensure that the refrigerator compartment temperature meets storage requirements. Balancing these compartment temperature requirements with a high-quality, low-noise experience remains a challenging issue within the industry.

[0051] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiments of the present application, an embodiment of a smart refrigerator control method is provided, such as Figure 1 As shown, the method may include the following steps:

[0052] Step S102, obtaining the current ambient temperature of the space where the refrigerator is located and the operating intensity of the noise source, wherein the noise source is the mechanical components inside the refrigerator;

[0053] Step S104: determining a first reference intensity that matches the ambient temperature based on a preset mapping relationship, and comparing the operating intensity with the first reference intensity to obtain a comparison result, wherein the preset mapping relationship is a correspondence between multiple ambient temperatures and a reference operating intensity that meets a predetermined storage temperature requirement of the refrigerator compartment at each ambient temperature;

[0054] Step S106: executing a noise reduction strategy that matches the comparison result.

[0055] Through the above steps S102 to S106, the present application first determines the benchmark operating intensity corresponding to the noise source through the current ambient temperature of the refrigerator, then compares the current operating intensity of the noise source with the benchmark operating intensity, and then executes the corresponding noise reduction strategy according to the comparison result. It can reduce noise while ensuring the compartment temperature storage requirements, improve user experience, and solve the technical problem that it is difficult to reduce noise while ensuring the compartment temperature storage requirements.

[0056] In step S102, the refrigerator may be a smart refrigerator with a mute function. The smart refrigerator may include an external temperature sensor to obtain the current ambient temperature of the space where the smart refrigerator is located. The main noise sources in smart refrigerators come from the compressor and fan motor. The compressor and fan motor are used to maintain a suitable storage temperature in the refrigerator compartment. The noise levels vary depending on the speed of the compressor and fan motor, and particularly at high speeds, the noise levels may affect the user experience.

[0057] In an optional embodiment, the noise source includes at least one of a compressor and a fan of the refrigerator, and the operating intensity is at least one of a rotation speed of the compressor and a rotation speed of the fan.

[0058] In an embodiment of the present application, when the smart refrigerator is in silent mode, it can intelligently adjust the speed of at least one of the compressor and fan motor on the basis of ensuring the compartment temperature storage requirement. That is, when the current speed of the compressor and fan motor is already much greater than the compartment temperature storage requirement, the following adjustment strategies can be adopted: first, completely stop the compressor or significantly reduce the speed of the compressor, and the fan motor continues to operate normally; second, completely stop the fan motor or significantly reduce the speed of the fan motor, and the compressor continues to operate normally; third, significantly reduce the speed of the compressor and fan motor at the same time. When the current speed of the compressor and fan motor is slightly greater than the compartment temperature storage requirement, the following adjustment strategies can be adopted: first, slightly reduce the speed of the compressor, and the fan motor continues to operate normally; second, slightly reduce the speed of the fan motor, and the compressor continues to operate normally; third, slightly reduce the speed of the compressor and fan motor at the same time. It should be noted that in the above strategies, the priority of adjusting the compressor or the fan motor can be selected based on the energy consumption of the two, such as prioritizing the component with higher energy consumption; the refrigeration efficiency of the two, such as prioritizing the component with lower refrigeration efficiency; and the noise level of the two, such as prioritizing the component with higher noise.

[0059] In the embodiment of the present application, the mute function can be selected on the display panel of the smart refrigerator to put the smart refrigerator into mute mode, and the mute function can also be selected on the terminal device wirelessly connected to the smart refrigerator to put the smart refrigerator into mute mode. The embodiment of the present application provides an optional display panel of the smart refrigerator, such as Figure 2 As shown, the panel features compartment and temperature selection, function selection, and a child lock button. A mute (noise reduction) function has been added to the selection options. The display panel communicates with the refrigerator's main control unit. When the mute (noise reduction) function is set, the mainboard controls the load according to the mute control mode.

[0060] In step S104, the predetermined storage temperature requirement of the refrigerator compartment can be a customized requirement based on customer habits, or a basic requirement, that is, a minimum temperature requirement for storing food, such as milk must be lowered to at least a certain temperature. The preset mapping relationship is the correspondence between multiple ambient temperatures and the benchmark operating intensity that meets the basic storage temperature requirement of the refrigerator compartment at each temperature, such as Figure 3 FIG. 1 is a schematic diagram of an optional preset mapping relationship provided in an embodiment of the present application. Figure 3As shown, the preset mapping relationship is the reference speed of the compressor and fan motor at different ambient temperatures. In the example provided, the ambient temperature is divided into six ambient temperature segments: less than 14 degrees, greater than or equal to 14 degrees and less than 19 degrees, greater than or equal to 19 degrees and less than 23 degrees, greater than or equal to 23 degrees and less than 29 degrees, greater than or equal to 29 degrees and less than 36 degrees, and greater than or equal to 36 degrees. In each ambient temperature segment, the reference speed of the compressor and fan motor is set. For example, when the ambient temperature is less than 14 degrees, the reference speed of the compressor is S1, and the fan speed is F1. The speeds of the compressor and fan motor can be linked or controlled independently. Figure 3 The figure shows the control relationship between the compressor and fan motor speeds. For example, when the compressor base speed is S1, the fan speed is F1. S1 is set to a low speed, and S6 is set to a high speed.

[0061] In the embodiment of the present application, in order to more accurately reduce the noise on the basis of ensuring the storage demand of the compartment temperature, the speed adjustment of the compressor and fan motor during operation is not only affected by the ambient temperature, but also can use more parameters as the basis for the implementation of the noise reduction strategy, such as the difference between the compartment temperature and the set temperature, the setting of the function selection, etc. to implement noise reduction. The greater the difference between the compartment temperature and the set temperature, the greater the compartment temperature storage demand. At this time, the speed of the compressor and fan motor can be reduced to a smaller extent, thereby giving priority to ensuring the compartment temperature storage demand. The noise reduction strategy and the degree of noise reduction can also be adjusted in real time according to the function selected by the user (such as rapid cooling, constant temperature, etc.).

[0062] In an embodiment of the present application, after obtaining the current ambient temperature of the space where the smart refrigerator is located and the operating intensity of the noise source, the first benchmark intensity that matches the ambient temperature can be determined according to the preset mapping relationship, and the operating intensity can be compared with the first benchmark intensity to obtain a comparison result. In subsequent steps, the corresponding noise reduction strategy can be executed according to the comparison result.

[0063] In this embodiment of the present application, the operating intensity of the compressor and fan motor can be divided into multiple gears according to this preset mapping relationship. Each gear corresponds to a baseline intensity. When implementing a real-time noise reduction strategy, it is necessary to first conduct a temperature demand test within the same gear or across gears. Then, based on the test results of the temperature demand test, the target intensity of the noise source noise reduction operation is determined. This is explained in detail below.

[0064] In step S106, executing a noise reduction strategy that matches the comparison result includes:

[0065] The first one is to execute the first noise reduction strategy when the comparison result shows that the operating intensity is greater than the first benchmark intensity, first performing a temperature requirement test in the first gear where the first benchmark intensity is located, and then determining the target intensity of the noise source noise reduction operation according to the test result of the temperature requirement test, and controlling the noise source to operate according to the target intensity.

[0066] In an embodiment of the present application, if the comparison result is that the operating intensity is greater than the first reference intensity, the current operating intensity of the compressor and / or fan motor can be reduced to the first reference intensity, and a temperature demand test can be performed at the first reference intensity. This is a temperature demand test performed within the same gear, the purpose of which is to detect whether the compartment temperature storage requirement can be met by running at the lowest speed (reference speed) of the current gear. If the compartment temperature storage requirement can be met by running at the lowest speed of the current gear, the speed is further reduced to further reduce the noise while ensuring the compartment temperature storage requirement. Otherwise, the operation is continued according to the first reference intensity to give priority to ensuring the compartment temperature storage requirement.

[0067] The second type is to execute the second noise reduction strategy when the comparison result shows that the operating intensity is less than or equal to the first benchmark intensity, first performing a temperature requirement test for downshifting based on the first gear, then determining the target intensity of the noise source noise reduction operation according to the test result of the temperature requirement test, and controlling the noise source to operate according to the target intensity.

[0068] In an embodiment of the present application, if the comparison result is that the operating intensity is less than or equal to the first reference intensity, the current operating intensity of the compressor and / or fan motor can be directly reduced by one gear, and a temperature demand test can be performed based on the speed after the downshift. This is a temperature demand test performed across gears, the purpose of which is to detect whether the compartment temperature storage requirement can be met when running at a lower gear. If the compartment temperature storage requirement can be met by running at a lower gear, then continue to reduce one gear to further reduce the noise while ensuring the compartment temperature storage requirement. Otherwise, continue to run at the current speed to give priority to ensuring the compartment temperature storage requirement.

[0069] The technical solution of this application can reduce noise to the greatest extent while ensuring the temperature storage requirements of the compartment and improve user experience.

[0070] In an optional embodiment, executing the first noise reduction strategy to first perform a temperature requirement test in a first gear at a first reference intensity, and then determining a target intensity of the noise source noise reduction operation based on a test result of the temperature requirement test includes:

[0071] Reduce the current operating intensity of the noise source to the first baseline intensity of the first gear and start timing;

[0072] If the noise source stops within the first preset time period, determining a second gear position adjacent to the first gear position and having an operating intensity lower than the first gear position, and determining a second reference intensity of the second gear position as a target intensity for noise reduction operation of the noise source;

[0073] If the noise source does not stop within the first preset time period, the first reference intensity of the current operation is determined as the target intensity of the noise source noise reduction operation;

[0074] The first preset duration is the maximum duration for meeting the predetermined storage temperature requirement of the refrigerator compartment when the noise source operates at the first reference intensity.

[0075] In an optional embodiment, executing a noise reduction strategy that matches the comparison result to reduce noise further includes:

[0076] If the noise source stops within the first preset time, the noise source will be operated according to the second reference intensity as the target intensity when it is started next time;

[0077] If the noise source does not stop within the first preset time period, the first reference intensity is used as the target intensity to continue operating.

[0078] In an embodiment of the present application, if the operating intensity is greater than a first baseline intensity, the current operating intensity is reduced to the first baseline intensity to reduce noise levels and perform a temperature requirement test. During the temperature requirement test, the operating time of the compressor and / or fan motor at the first baseline intensity is measured. Within a first preset duration, it is determined whether the compressor and / or fan motor has shut down. If so, the next time the compressor and / or fan motor is turned on, the speed is reduced by one gear from the compressor and / or fan motor speed before the shutdown, i.e., the speed is reduced to the second baseline intensity of the second gear. If the first gear is already the lowest gear, the operation continues at the first baseline intensity of the first gear. The first preset duration is the maximum duration that the noise source can meet the basic storage temperature requirement of the refrigerator compartment when operating at the first baseline intensity. If the compressor and / or fan motor is detected to be shut down within the first preset duration, it can be determined that the cooling capacity generated by the compressor and / or fan motor at the first baseline intensity can also meet the compartment temperature requirement. The gear can then be further reduced, thereby both meeting the compartment temperature requirement and minimizing the user's perception of operating noise. If it is detected that the compressor and / or fan motor is not shut down within the first preset time, the compressor and / or fan motor will continue to operate according to the first reference intensity to give priority to meeting the temperature demand of the compartment, and no downshifting will be performed.

[0079] In an optional embodiment, executing the second noise reduction strategy to first perform a temperature requirement test for downshifting based on the first gear, and then determining a target intensity of noise source noise reduction operation based on the test result of the temperature requirement test includes:

[0080] determining a second gear position adjacent to the first gear position and having a lower operating intensity than the first gear position;

[0081] Reduce the current operating intensity of the noise source to the second benchmark intensity of the second gear and start timing;

[0082] If the noise source stops within the second preset time period, determining a third gear position adjacent to the second gear position and having an operating intensity lower than the second gear position, and determining a third reference intensity in the third gear position as a target intensity for noise reduction operation of the noise source;

[0083] If the noise source does not stop within the second preset time period, the second reference intensity of the current operation is determined as the target intensity of the noise source noise reduction operation;

[0084] The second preset duration is the maximum duration for meeting the predetermined storage temperature requirement of the refrigerator compartment when the noise source is operating at the second reference intensity.

[0085] In an optional embodiment, executing a noise reduction strategy that matches the comparison result to reduce noise further includes:

[0086] If the noise source stops within the second preset time period, the noise source will be operated according to the third reference intensity as the target intensity when it is started next time;

[0087] If the noise source does not stop within the second preset time period, the second reference intensity is used as the target intensity to continue operating.

[0088] In an embodiment of the present application, if the operating intensity is less than or equal to the first reference intensity, the current operating intensity is directly reduced by one gear, that is, reduced to the second reference intensity of the second gear, so as to reduce the noise value and perform a temperature requirement test. If the first gear is already the lowest gear, continue to operate according to the first reference intensity of the first gear. During the temperature requirement test, the operating time of the compressor and / or fan motor that is reduced to the second reference intensity is timed, and within the second preset time, it is determined whether the compressor and / or fan motor is shut down. If so, when the compressor and / or fan motor is turned on next time, it is reduced by one gear based on the speed of the compressor and / or fan motor before the shutdown, that is, reduced to the third reference intensity of the third gear. If the second gear is already the lowest gear, continue to operate according to the second reference intensity of the second gear. The second preset duration is the maximum duration for meeting the basic storage temperature requirement of the refrigerator compartment when the noise source is operating at the second reference intensity. If the compressor and / or fan motor is detected to be shut down within the second preset duration, it can be determined that the cooling capacity generated by the operation of the compressor and / or fan motor at the second reference intensity can also meet the compartment temperature requirement, and the gear can be further reduced, thereby meeting the compartment temperature requirement and minimizing the user's perception of the operating noise. If the compressor and / or fan motor is detected to be not shut down within the second preset duration, it will continue to operate according to the second reference intensity to give priority to meeting the compartment temperature requirement, and no downshifting will be performed.

[0089] In an optional embodiment, after executing the noise reduction strategy that matches the comparison result, the method further includes:

[0090] After each execution of the noise reduction strategy, the target intensity of the noise source noise reduction operation is determined to be a new reference intensity that matches the current ambient temperature, so as to update the preset mapping relationship.

[0091] In an embodiment of the present application, during the actual use of the smart refrigerator, the reference intensity corresponding to each ambient temperature can be optimized in real time according to the actual situation, so that the preset mapping relationship can be continuously updated and optimized according to the actual environment where the smart refrigerator is located, so that the smart refrigerator can be more suitable for the specific use environment and improve the user experience.

[0092] like Figure 4 An optional mute control logic provided in an embodiment of the present application is shown, and the mute control logic is generally described below.

[0093] like Figure 4As shown in the figure, after the user activates the [Mute] function, the current ambient temperature, compressor speed, and fan speed are obtained. The current speed (compressor speed and / or fan speed) is first compared with the reference speed. If the current speed is greater than the reference speed, it is reduced to the reference speed. The system then determines whether the compressor and / or fan have stopped within a preset time. If the compressor and / or fan have stopped, the system will operate at a speed one gear lower than the pre-stop speed (if it is the lowest speed, it will operate at the lowest speed) the next time it is restarted. If the compressor and / or fan have not stopped, the system will continue to operate at the reference speed. If the current speed is less than or equal to the reference speed, the system will reduce the speed by one gear lower than the current reference speed (if it is the lowest speed, it will operate at the lowest speed). The system then determines whether the compressor and / or fan have stopped within a preset time. If the compressor and / or fan have stopped, the system will reduce the speed by another gear lower than the pre-stop speed (if it is the lowest speed, it will operate at the lowest speed) the next time it is restarted. If the compressor and / or fan have not stopped, the system will continue to operate at the current speed.

[0094] This application first determines the benchmark operating intensity corresponding to the noise source through the current ambient temperature of the refrigerator, then compares the current operating intensity of the noise source with the benchmark operating intensity, and then executes the corresponding noise reduction strategy according to the comparison result. It can reduce noise while ensuring the compartment temperature storage requirements, improve user experience, and solve the technical problem that it is difficult to reduce noise while ensuring the compartment temperature storage requirements.
