Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a control method for a refrigeration and freezing apparatus, a machine-readable storage medium, and a refrigeration and freezing apparatus. Background Technology

[0002] Currently, with the continuous improvement of living standards, consumers have increasingly higher requirements for the quietness of refrigerators. Refrigerator noise is a significant factor affecting its quietness. Existing refrigerators typically determine whether to exit or continue in quiet mode based on the compartment temperature. However, if the compartment temperature exceeds a threshold when a user is just falling asleep or preparing to fall asleep, the refrigerator will exit quiet mode. This can cause the refrigerator to emit significant noise, affecting the user's sleep or reducing sleep quality. Therefore, the existing refrigerator's quietness control logic is simplistic and cannot meet users' specific quietness needs, thus reducing the user experience. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a control method, machine-readable storage medium and refrigeration and freezing device for overcoming or at least partially solving the above problems, which can solve the problem that the single silent control logic cannot meet the user's special silent needs, so as to improve the user experience.

[0004] Specifically, the present invention provides a control method for a refrigeration and freezing apparatus, comprising:

[0005] During the silent mode operation, time parameters and room temperature of each room are acquired;

[0006] Based on the time parameters and the compartment temperature, the refrigeration and freezing unit is controlled to exit silent mode or continue operating in silent mode.

[0007] Optionally, the time parameter includes the current time and / or the duration of the silent mode.

[0008] Optionally, controlling the refrigeration / freezing unit to exit silent mode or continue operating in silent mode based on the time parameter and the compartment temperature includes:

[0009] Determine whether the time parameter meets the preset time condition;

[0010] If so, continue running the silent mode;

[0011] If not, then based on the compartment temperature, control the refrigeration and freezing unit to exit silent mode or continue operating in silent mode.

[0012] Optionally, the time parameter includes the current time, and the preset time condition is that the current time is less than a set time point; or

[0013] The time parameter includes the duration of operation of the silent mode, and the preset time condition is that the duration of operation is less than a set duration; or

[0014] The time parameter includes the current time and the duration of the silent mode. The preset time condition is: the current time is less than a set time point, or the duration of the silent mode is less than a set duration.

[0015] The set time point is located within a preset silent time period, and the set duration is less than the total duration corresponding to the preset silent time period.

[0016] Optionally, controlling the refrigeration / freezing unit to exit silent mode or continue operating in silent mode based on the compartment temperature includes:

[0017] Determine whether the temperature of each compartment is greater than a corresponding preset threshold; wherein the preset threshold of each compartment is greater than or equal to a corresponding set temperature;

[0018] If so, exit the silent mode;

[0019] If not, the silent mode will continue to run.

[0020] Optionally, when the preset silent period falls at night, the set time is from 11 PM to midnight, and the set duration is from 1 hour to 3 hours; or

[0021] When the preset silent period falls during the daytime, the set time is from 11:00 to 12:00, and the set duration is from 1 hour to 3 hours.

[0022] Optionally, after exiting the silent mode, the method further includes:

[0023] Control the refrigeration and freezing unit to operate in either low-temperature mode or normal mode;

[0024] When the temperature of each of the rooms is less than or equal to the set temperature, determine whether the current time is within the preset quiet time period;

[0025] If so, the refrigeration and freezing device will be controlled to operate in silent mode.

[0026] Optionally, the mute mode includes a first mute mode and / or a second mute mode and / or a third mute mode:

[0027] The first silent mode includes: controlling the compressor to stop;

[0028] The second silent mode includes: controlling the compressor to execute a preset compressor speed and / or controlling the fan to execute a preset fan speed; wherein, the preset compressor speed is the compressor speed with the lowest noise level when the refrigeration and freezing unit is operating only the compressor, and the preset compressor speed is within the rated compressor speed range; the preset fan speed is the fan speed with the lowest noise level when the refrigeration and freezing unit is operating only the fan, and the preset fan speed is within the rated fan speed range;

[0029] The third silent mode includes: controlling the compressor to reduce the compressor speed and / or controlling the fan to reduce the fan speed.

[0030] Optionally, the silent mode includes a first silent mode; and

[0031] The control method further includes: when the refrigeration and freezing device meets the silent mode start-up conditions, determining whether the number of days the first silent mode has been running within a preset time period is less than a preset number of days; if so, controlling the refrigeration and freezing device to run the first silent mode; wherein, the first silent mode includes: controlling the compressor to stop.

[0032] On the other hand, the present invention also provides a machine-readable storage medium having a machine-executable program stored thereon, which, when executed by a processor, implements the control method as described in any of the preceding claims.

[0033] In another aspect, the present invention also provides a refrigeration and freezing apparatus, including a controller, the controller including a memory, a processor and a machine-executable program stored in the memory and running on the processor, and the processor, when executing the machine-executable program, implements the control method as described in any of the above.

[0034] In the control method, machine-readable storage medium, and refrigeration and freezing device of the present invention, during the operation of silent mode, the refrigeration and freezing device is controlled to exit silent mode or continue operating silent mode based on two factors: time parameter and compartment temperature. Since users are more sensitive to noise when preparing to fall asleep or just falling asleep, and noise has a relatively small impact on sleep quality when users are in deep sleep, the need for silence varies at different times within the preset silent period. This means that the user's biological clock is a crucial factor in determining whether to execute silent mode, and the time parameter is related to the user's biological clock. Therefore, the present invention determines whether to exit silent mode or continue operating silent mode based on compartment temperature and time parameter, which can meet the user's silence needs at different times, thereby improving the user experience. Compared with the prior art, which determines whether to exit silent mode based solely on compartment temperature, the present invention solves the problem that the single silent control logic cannot meet the specific silent needs of users.

[0035] Furthermore, the control method of the present invention has the advantages of simple control procedures and easy execution.

[0036] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0049] Figure 1 This is a schematic flowchart of a control method for a refrigeration and freezing apparatus 100 according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 7 This invention provides a control method for a refrigeration and freezing device 100, which may include the following steps:

[0050] S100 acquires time parameters and room temperature of each compartment during silent mode operation;

[0051] S200 controls the refrigeration and freezing unit to exit silent mode or continue running silent mode based on time parameters and compartment temperature.

[0052] Specifically, during the operation of silent mode, the refrigeration and freezing unit 100 is controlled to either exit silent mode or continue operating in silent mode based on two factors: time parameters and compartment temperature. Since users are more sensitive to noise when preparing to fall asleep or just falling asleep, and noise has a relatively smaller impact on sleep quality when users are in deep sleep, the need for silence varies at different times within the preset silent period. This means that the user's biological clock is a crucial factor in determining whether to execute silent mode, and the time parameter is related to the user's biological clock. Therefore, this invention determines whether to exit or continue silent mode based on compartment temperature and time parameters, satisfying the user's silence needs at different times, thereby improving the user experience. Compared with existing technologies that determine whether to exit silent mode solely based on compartment temperature, this invention solves the problem of a single silent control logic that cannot meet the specific silent needs of users.

[0053] In some optional embodiments of the present invention, the time parameter includes the current time and / or the duration of operation of the silent mode. Specifically, the time parameter includes the current time; or, the time parameter includes the duration of operation of the silent mode; or, the time parameter includes both the current time and the duration of operation of the silent mode.

[0054] S200 includes: controlling the operating mode of the refrigeration / freezing unit based on the compartment temperature and current time, or based on the compartment temperature and elapsed running time, or based on the compartment temperature, current time, and elapsed running time, to exit silent mode or continue operating in silent mode. The current time and the elapsed running time in silent mode are two important time parameters associated with the user's biological clock. Therefore, this invention determines whether to exit silent mode or continue operating silent mode based on the compartment temperature, current time, and / or the elapsed running time in silent mode, which can meet the user's silent needs at different times, thereby improving the user experience.

[0055] like Figure 2 As shown, in some optional embodiments of the present invention, S200, controlling the refrigeration and freezing unit to exit silent mode or continue operating in silent mode according to time parameters and compartment temperature may include the following steps:

[0056] S210, determine whether the time parameter meets the preset time condition; if yes, execute S220; if no, execute S230.

[0057] S220, continuously running in silent mode.

[0058] S230 controls the refrigeration and freezing unit to exit silent mode or continue running silent mode based on the compartment temperature.

[0059] This embodiment provides a specific method for noise control, which has the advantages of simple and easy-to-execute control procedures. Specifically, since users are more sensitive to noise when preparing to fall asleep or just falling asleep, during the operation of the silent mode, it is preferable to determine whether the time parameter meets the preset time condition. When the time parameter meets the preset time condition, the silent mode is controlled to run, which can help users fall asleep or improve sleep quality. In addition, since noise has less impact on sleep quality when users are in deep sleep, it is preferable to ensure the preservation effect of the compartment. Therefore, when the time parameter does not meet the preset time condition, the refrigeration and freezing device is controlled to exit the silent mode or continue to run the silent mode according to the compartment temperature, which is beneficial to improving the preservation effect of food and has virtually no adverse effect on sleep quality.

[0060] In some optional embodiments of the present invention, the time parameter includes the current time, and the preset time condition is that the current time is less than a set time point. The set time point is located within a preset silent time period. Specifically, if the current time is less than the set time point, it indicates that the user is preparing to fall asleep or has just fallen asleep. Running the silent mode at this time can help the user fall asleep or improve sleep quality. If the current time is not less than the set time point, it indicates that the user has entered deep sleep. Executing step S230 at this time is beneficial for improving the preservation effect of food and has virtually no adverse effect on sleep quality.

[0061] In some optional embodiments of the present invention, the time parameter includes the elapsed duration of the silent mode, with a preset time condition that the elapsed duration is less than a set duration. The set duration is less than the total duration corresponding to the preset silent time period. Specifically, if the elapsed duration is less than the set duration, it indicates that the user is preparing to fall asleep or has just fallen asleep. Running the silent mode at this time can help the user fall asleep or improve sleep quality. If the current time is not less than the set time point, it indicates that the user has entered deep sleep. Executing step S230 at this time is beneficial for improving the preservation effect of food and will not have a significant adverse impact on sleep quality.

[0062] In some optional embodiments of the present invention, the time parameters include the current time and the elapsed duration of the silent mode. The preset time condition is: the current time is less than a set time point, or the elapsed duration is less than a set duration; wherein the set time point is within a preset silent time period, and the set duration is less than the total duration corresponding to the preset silent time period. Specifically, during the operation of the silent mode, if the current time is less than the set time point or the elapsed duration is less than the set duration, step S220 is executed; if the current time is less than the set time point and the elapsed duration is less than the set duration, step S230 is executed. In this embodiment, the time parameters include the current time and the elapsed duration of the silent mode, which can avoid misjudgment, thereby improving control accuracy and ultimately enhancing the user experience.

[0063] like Figure 3 As shown, in some optional embodiments of the present invention, S230, controlling the refrigeration and freezing device to exit silent mode or continue operating in silent mode according to the compartment temperature may include the following steps:

[0064] S231, determine whether the temperature of each compartment is greater than the corresponding preset threshold; if yes, proceed to S232; if no, proceed to S220.

[0065] S232, Exit silent mode;

[0066] S220, continuously running in silent mode.

[0067] Each compartment has a preset threshold temperature greater than or equal to its corresponding set temperature, which can be set as needed. For example, the preset threshold temperature for the refrigeration compartment can be 5°C, the preset threshold temperature for the freezing compartment can be 5°C, and the preset threshold temperature for the variable temperature compartment can be 3°C. In this embodiment, the control method described herein ensures the preservation effect of the refrigeration and freezing device.

[0068] In some optional embodiments of the present invention, before S100, the control method further includes the following step: when the refrigeration and freezing device meets the silent mode start-up conditions, the refrigeration and freezing device is controlled to operate in silent mode.

[0069] The conditions for activating silent mode may include at least one of the following:

[0070] The current time has reached the start time of the preset silent period;

[0071] The temperature of each compartment is lower than a first temperature; wherein the first temperature is less than or equal to a set temperature; preferably, the first temperature is lower than the set temperature.

[0072] In some optional embodiments of the present invention, the preset silent time period is a preset silent time period within the refrigeration and freezing device 100.

[0073] Furthermore, the refrigeration and freezing unit 100 can be preset with multiple quiet time periods, which users can select according to their needs.

[0074] Furthermore, the refrigeration and freezing unit 100 has two preset quiet periods: one preset quiet period is from 22:00 to 6:00 the next day; the other preset quiet period is from 10:00 to 18:00.

[0075] In some optional embodiments of the present invention, the preset silent period is the silent period set by the user through a mobile APP.

[0076] In some optional embodiments of the present invention, the preset silent period is the silent period set by the user via the cloud.

[0077] In some optional embodiments of the present invention, the preset silent period is the silent period set by the user through the control panel or display screen of the refrigeration and freezing device 100.

[0078] In the three embodiments described above, users can set the desired silent period as needed. In other words, the start time, end time, and total duration of the silent period can all be customized according to user needs.

[0079] In some optional embodiments of the present invention, when the preset silent period falls at night, the set time is from 11 PM to midnight (e.g., 11 PM, 11:30 PM, or midnight), and the set duration is from 1 hour to 3 hours (e.g., 1 hour, 1.5 hours, 2 hours, 2.5 hours, or 3 hours). Preferably, when the preset silent period falls at night, the set time is midnight, and the set duration is 2 hours.

[0080] In some optional embodiments of the present invention, when the preset silent period falls during the daytime, the set time is 11:00 to 12:00 (e.g., 11:00, 11:30, or 12:00), and the set duration is 1 hour to 3 hours (e.g., 1 hour, 1.5 hours, 2 hours, 2.5 hours, or 3 hours). Preferably, when the preset silent period falls during the daytime, the set time is 12:00, and the set duration is 2 hours.

[0081] like Figure 4 As shown, in some optional embodiments of the present invention, after step S232, the control method may further include the following steps:

[0082] S240 controls whether the refrigeration and freezing unit operates in low-temperature mode or normal mode;

[0083] S250: When the temperature of each room is less than or equal to the set temperature, determine whether the current time is within the preset silent period; if so, execute S260.

[0084] S260 controls the silent operation mode of the refrigeration and freezing unit.

[0085] In this embodiment, the above method can increase the total actual operating time of the refrigeration and freezing device in silent mode within the preset silent time period, thereby further improving the user's silent experience.

[0086] In some alternative embodiments of the present invention, the silent mode includes at least one of a first silent mode, a second silent mode, and a third silent mode.

[0087] The first silent mode includes: controlling the compressor to stop.

[0088] The second silent mode includes: controlling the compressor to execute a preset compressor speed and / or controlling the fan to execute a preset fan speed. The preset compressor speed is the compressor speed with the lowest noise level when only the compressor is running, and the preset compressor speed is within the rated compressor speed range; the preset fan speed is the fan speed with the lowest noise level when only the fan is running, and the preset fan speed is within the rated fan speed range.

[0089] The third silent mode includes: controlling the compressor to reduce the compressor speed and / or controlling the fan to reduce the fan speed.

[0090] Specifically, in the second silent mode, the method for obtaining the preset compressor speed may include the following steps: obtaining several compressor speed values ​​within the rated compressor speed range; under the condition that the refrigeration and freezing unit only operates the compressor and does not operate the fan, obtaining the noise value of the refrigeration and freezing unit when the compressor operates at each of the above-mentioned compressor speed values, and obtaining multiple noise values; taking the compressor speed value corresponding to the smallest noise value among the multiple noise values ​​as the preset compressor speed.

[0091] A method for obtaining a preset fan speed may include the following steps: obtaining several fan speed values ​​within the rated fan speed range; under the condition that the refrigeration and freezing unit only operates the fan and does not operate the compressor, obtaining the noise value of the refrigeration and freezing unit when the fan operates at each of the above-mentioned fan speed values, and obtaining multiple noise values; taking the fan speed value corresponding to the minimum noise value among the multiple noise values ​​as the preset fan speed.

[0092] Noise levels in refrigeration and freezing systems are influenced by various factors, with the compressor and fan being the primary sources. However, compressor speed and noise levels are not directly correlated; that is, a lower compressor speed does not necessarily mean lower noise. Similarly, fan speed and noise levels are not directly correlated; a lower fan speed does not necessarily mean lower noise.

[0093] Therefore, among the three silent modes mentioned above, the first silent mode provides the best noise reduction effect. The second silent mode is more effective than the third silent mode.

[0094] In some optional embodiments of the present invention, the silent mode includes a first silent mode. The control method may further include the following steps: when the refrigeration and freezing device meets the silent mode start-up conditions, determining whether the number of days the first silent mode has been running within a preset time period is less than a preset number of days; if so, controlling the refrigeration and freezing device to run the first silent mode; wherein, the first silent mode includes: controlling the compressor to stop.

[0095] Specifically, the preset time period can be 7 days, 10 days, 15 days, 20 days, 25 days, or 30 days; correspondingly, the preset number of days can be selected according to the preset time period.

[0096] For example, when the preset time limit is 30 days, the preset number of days is 15 to 20 days.

[0097] The method described in this embodiment helps to better balance noise reduction and food preservation, thus avoiding situations where noise reduction severely affects the freshness of food in the storage room.

[0098] Furthermore, if the number of days the first silent mode has been running within the preset time period is not less than the preset number of days, then the refrigeration and freezing unit is controlled to run in the second or third silent mode.

[0099] like Figure 5 As shown, in a preferred embodiment of the present invention, the control method of the refrigeration and freezing apparatus includes the following steps:

[0100] S1. When the refrigeration and freezing unit meets the conditions for starting the silent mode, determine whether the number of days the first silent mode has been running within the preset time period is less than the preset number of days; if so, execute S2.

[0101] S2 controls the refrigeration and freezing unit to operate in the first silent mode in order to control the compressor to stop;

[0102] S3, get the current time and the runtime of the first silent mode;

[0103] S4, determine whether the current time is less than the set time point or whether the running time is less than the set duration; if yes, execute S2; if no, execute S5.

[0104] S5, obtain the room temperature of each compartment;

[0105] S6, determine whether the temperature of each compartment is greater than the corresponding preset threshold; if yes, proceed to S7; if no, proceed to S2.

[0106] S7 controls the refrigeration and freezing unit to exit silent mode and start the low-temperature operation;

[0107] S8, determine whether the temperature of each room is less than or equal to the set temperature; if yes, proceed to S9; if no, proceed to S7.

[0108] S9, determine if the current time is within the preset silent period; if so, execute S2.

[0109] The set time point falls within a preset quiet period, and the set duration is less than the total duration corresponding to the preset quiet period. The preset threshold for each room is greater than the corresponding set temperature.

[0110] In this embodiment, when the refrigeration and freezing device meets the silent mode activation conditions and the number of days the first silent mode has been running within a preset time period is less than a preset number of days, the compressor is controlled to stop to run the first silent mode. Compared with other silent modes, the first silent mode has the best noise reduction effect. Furthermore, during the operation of the first silent mode, if the current time is less than a set time point or the current running time of the silent mode is less than a set duration, the silent mode continues to run, thereby helping the user fall asleep or improve sleep quality.

[0111] In some optional embodiments of the present invention, the refrigeration and freezing device 100 can be a freezer, a beverage refrigerator, a fresh food refrigerator, or a refrigerator, etc.

[0112] Figure 6 This is a schematic diagram of a machine-readable storage medium 200 according to an embodiment of the present invention, as shown below. Figure 6 As shown, this embodiment of the invention also provides a machine-readable storage medium 200, on which a machine-executable program 201 is stored. When the machine-executable program 201 is executed by the processor 132, it implements the control method of the refrigeration and freezing apparatus 100 according to any of the above embodiments.

[0113] It should be noted that the logic and / or steps represented in the flowchart or otherwise described herein, for example, can be considered as a sequenced list of executable instructions for implementing logical functions, and can be specifically implemented in any machine-readable storage medium 200 for use by, or in conjunction with, an instruction execution system, apparatus or device (such as a computer-based system, a system including processor 132 or other system that can fetch and execute instructions from an instruction execution system, apparatus or device).

[0114] For the purposes of this embodiment, the machine-readable storage medium 200 can be any means capable of containing, storing, communicating, propagating, or transmitting a program for use by or in conjunction with an instruction execution system, apparatus, or device.

Furthermore, the machine-readable storage medium 200 can even be paper or other suitable media on which the program can be printed, since the program can be obtained electronically, for example, by optically scanning the paper or other medium, followed by editing, interpreting, or otherwise processing as necessary, and then stored in the memory 131.

[0115] Figure 7 This is a schematic diagram of a refrigeration and freezing apparatus 100 according to an embodiment of the present invention, as shown below. Figure 7As shown, this embodiment of the invention also provides a refrigeration and freezing apparatus 100, which includes a controller 130. The controller 130 includes a memory 131, a processor 132, and a machine-executable program 201 stored in the memory 131 and running on the processor 132. When the processor 132 executes the machine-executable program 201, it implements the control method of the refrigeration and freezing apparatus according to any of the above embodiments.

[0116] Specifically, controller 130 may include processor 132 adapted to execute stored instructions and memory 131 providing temporary storage space for the operation of said instructions during operation. Processor 132 may be a single-core processor 132, a multi-core processor 132, a computing cluster, or any other configuration. Memory 131 may include random access memory 131 (RAM), read-only memory 131, flash memory, or any other suitable storage system.

[0117] The processor 132 can be connected via a system interconnect (e.g., PCI, PCI-Express, etc.) to an I / O interface (input / output interface) suitable for connecting the refrigeration unit 100 to one or more I / O devices (input / output devices). The I / O devices may include, for example, a keyboard and indicating devices, wherein the indicating devices may include a touchpad or a touch screen, etc.

[0118] The processor 132 may also be linked via a system interconnect to a display interface suitable for connecting the controller 130 to a display device. The display device may include a display screen that is a built-in component of the controller 130. The display device may also include a computer monitor, television, or projector externally connected to the refrigeration unit 100. Furthermore, a network interface controller (NIC) may be adapted to connect the controller 130 to a network via a system interconnect. In some embodiments, the NIC may use any suitable interface or protocol (such as an Internet Minicomputer System Interface) to transmit data.
