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. The main sources of refrigerator noise include the operating noise of the compressor at the bottom of the refrigerator, the noise from the thermal expansion and contraction or ejection of the evaporator or condenser, the operating noise of the refrigeration fan, the operating noise of the freezer fan, and the noise of refrigerant flowing in the pipes. Existing refrigerators typically reduce noise in quiet mode by reducing the compressor speed and / or the fan speed. However, because refrigerator noise is affected by various factors, these noise reduction methods are not effective, resulting in poor quietness and a reduced user experience. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a control method, a machine-readable storage medium, and a refrigeration and freezing device for overcoming or at least partially solving the above problems, which can solve the problem of poor noise reduction in existing silent modes and improve the user experience.

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

[0005] When the refrigeration and freezing unit meets the start-up conditions for silent mode, the compressor and / or fan are controlled to stop.

[0006] After the compressor and / or the fan has been shut down for a first period of time, the actual ambient temperature is obtained, and the speed of the compressor and / or the fan is controlled according to the actual ambient temperature.

[0007] Optionally, controlling the speed of the compressor and / or the fan based on the actual ambient temperature includes:

[0008] If the actual ambient temperature is less than or equal to the preset ambient temperature, the compressor is controlled to run at a first compressor speed, and / or the fan is controlled to run at a first fan speed;

[0009] If the actual ambient temperature is greater than the preset ambient temperature, control the compressor to run at a second compressor speed, and / or control the fan to run at a second fan speed;

[0010] The second compressor has a higher speed than the first compressor, and the second fan has a higher speed than the first fan.

[0011] Optionally, the first compressor speed is the compressor speed with the lowest noise level when the refrigeration and freezing unit is operating only the compressor, and the first compressor speed is within the rated compressor speed range; and / or

[0012] The first fan speed is the fan speed with the lowest noise level when the refrigeration and freezing device is operating only the fan, and the first fan speed is within the rated fan speed range.

[0013] Optionally, the control method further includes:

[0014] Obtain the room temperature of each compartment;

[0015] Determine whether the greenhouse chamber meets the exit conditions for silent mode;

[0016] If not, then perform the steps of obtaining the actual ambient temperature and controlling the speed of the compressor and / or the fan according to the actual ambient temperature.

[0017] Optionally, the exit condition includes: the difference between the room temperature of any room and the corresponding first target temperature is greater than a temperature threshold.

[0018] Optionally, the first target temperature of each room is greater than the corresponding user-set temperature.

[0019] Optionally, the step of obtaining the actual ambient temperature and controlling the speed of the compressor and / or the fan based on the actual ambient temperature further includes, before:

[0020] Determine if the room temperature is greater than the first target temperature;

[0021] If so, then perform the steps of obtaining the actual ambient temperature and controlling the speed of the compressor and / or the fan according to the actual ambient temperature;

[0022] If not, then control the compressor and / or the fan to continue to shut down.

[0023] Optionally, the control method further includes:

[0024] If the greenhouse chamber meets the exit conditions for the silent mode, then the silent mode is exited, and the compressor is controlled to execute the third compressor speed, and / or the fan is controlled to execute the third fan speed;

[0025] When the temperature of each of the compartments is less than or equal to the corresponding second target temperature, determine whether the current time is within the preset silent time period.

[0026] If so, then perform the step of controlling the compressor and / or fan to stop, or perform the step of controlling the speed of the compressor and / or the fan according to the actual ambient temperature.

[0027] 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.

[0028] 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.

[0029] In the control method, machine-readable storage medium, and refrigeration and freezing apparatus of the present invention, the silent mode is divided into two stages. Upon entering silent mode, the first stage is initiated by controlling the compressor and / or fan to stop, thereby reducing noise. After a preset time of compressor and / or fan shutdown, the second stage can be initiated, where the compressor and fan speeds are controlled according to the actual ambient temperature. Compared with existing technologies, the present invention significantly improves the quietness of the silent mode, thereby enhancing the user experience. Furthermore, controlling the compressor and / or fan speeds according to the actual ambient temperature better balances quietness and preservation effectiveness.

[0030] Furthermore, the control method of the present invention has the advantages of simple control procedures and easy execution.

[0044] 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 refer to Figures 2 to 5 This invention provides a control method for a refrigeration and freezing device 100, which may include the following steps:

[0045] S100, when the refrigeration and freezing unit 100 meets the start conditions of the silent mode, the compressor 110 and / or fan 120 are controlled to stop to enter the silent mode;

[0046] S200: After a preset time has elapsed since the compressor 110 and / or the fan 120 stopped, the actual ambient temperature is obtained, and the speed of the compressor 110 and / or the fan 120 is controlled according to the actual ambient temperature.

[0047] Specifically, in S100, "controlling the compressor 110 and / or the fan 120 to stop" includes the following and several situations: ① controlling the compressor 110 to stop; ② controlling the fan 120 to stop; ③ controlling both the compressor 110 and the fan 120 to stop. In S200, the actual ambient temperature refers to the ambient temperature of the space where the refrigeration and freezing unit 100 is located. The preset duration can be set as needed. Preferably, the preset duration can be from 0.5h to 3h, for example, 0.5h, 1h, 2h, 2.5h, or 3h.

[0048] The silent mode in this invention consists of two stages. Upon entering silent mode, the first stage involves stopping the compressor 110 and / or fan 120 to reduce noise. After a preset time of shutdown, the second stage begins, controlling the speed of the compressor 110 and / or fan 120 according to the actual ambient temperature. Compared to existing technologies, this invention significantly improves the quietness of the silent mode, enhancing the user experience. Furthermore, controlling the speed of the compressor 110 and / or fan 120 based on the actual ambient temperature better balances quiet operation and preservation.

[0049] In some alternative embodiments of the present invention, the refrigeration and freezing apparatus 100 includes compartments, a compressor 110, and / or a fan 120. The number of compartments in the refrigeration and freezing apparatus 100 may be one, two, three, four, or more.

[0050] like Figure 2 As shown, in some optional embodiments of the present invention, step S200, which involves controlling the speed of compressor 110 and / or fan 120 according to the actual ambient temperature, includes:

[0051] S201, if the actual ambient temperature is less than or equal to the preset ambient temperature, control the compressor 110 to execute the first compressor speed, and / or control the fan 120 to execute the first fan speed.

[0052] S202, if the actual ambient temperature is greater than the preset ambient temperature, control the compressor 110 to execute the second compressor speed, and / or control the fan 120 to execute the second fan speed.

[0053] Among them, the second compressor has a higher speed than the first compressor, and the second fan has a higher speed than the first fan.

[0054] Specifically, when the actual ambient temperature is less than or equal to the preset ambient temperature, step S201 is executed. Step S201 includes the following three cases: ① Controlling the compressor 110 to execute the first compressor speed. ② Controlling the fan 120 to execute the first fan speed. ③ Controlling the compressor 110 to execute the first compressor speed and controlling the fan 120 to execute the first fan speed. When the actual ambient temperature is greater than the preset ambient temperature, step S202 is executed. Step S202 includes the following three cases: ① Controlling the compressor 110 to execute the second compressor speed. ② Controlling the fan 120 to execute the second fan speed. ③ Controlling the compressor 110 to execute the second compressor speed and controlling the fan 120 to execute the second fan speed. The preset ambient temperature can be set as needed. Preferably, the preset ambient temperature is between 20°C and 45°C, for example, 20°C, 25°C, 30°C, 35°C, 40°C, or 45°C. In this embodiment, when the actual ambient temperature is high, a relatively high compressor speed and / or fan speed is used, which can better balance noise reduction and cooling effect.

[0055] In some optional embodiments of the present invention, in step S201, the first compressor speed is the compressor speed with the lowest noise level corresponding to the refrigeration and freezing unit 100 when only the compressor 110 is running, wherein the first compressor speed is within the rated compressor speed range. In some alternative embodiments, the first compressor speed may also be the lower limit of the rated compressor speed range.

[0056] Specifically, the speed of the first compressor is preset on the controller of the refrigeration and freezing unit 100.

[0057] The method for obtaining the first compressor speed may include the following steps: obtaining several compressor speed values ​​within the rated compressor speed range; under the operating condition that the refrigeration and freezing unit 100 only operates the compressor 110 and does not operate the fan 120, obtaining the noise value of the refrigeration and freezing unit 100 when the compressor 110 operates at 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 first compressor speed.

[0058] The noise of the refrigeration and freezing unit 100 is affected by various factors, among which the compressor 110 is the main source of noise. However, the compressor speed and the noise of the refrigeration and freezing unit 100 are not positively correlated; that is, a lower compressor speed does not necessarily mean lower noise. Therefore, when the actual ambient temperature is less than or equal to the preset ambient temperature, operating at the compressor speed with the lowest noise level can further improve the quietness effect.

[0059] Furthermore, the speed of the first blower can be set according to the speed of the first compressor. That is to say, the speed of the blower is related to the speed of the compressor; generally, when the compressor speed is low, the speed of the blower is also low, and vice versa.

[0060] In some optional embodiments of the present invention, in step S201, the first fan speed is the fan speed with the lowest noise level when only the fan 120 is running in the refrigeration and freezing device 100, and the first fan speed is within the rated fan speed range. In some optional embodiments, the first fan speed is the lower limit of the rated fan speed range.

[0061] The method for obtaining the first 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 device 100 only operates the fan 120 and does not operate the compressor 110, obtaining the noise value of the refrigeration and freezing device 100 when the fan 120 operates at the above-mentioned fan speed values, and obtaining multiple noise values; taking the fan speed value corresponding to the smallest noise value among the multiple noise values ​​as the first preset fan speed.

[0062] The noise of the refrigeration and freezing unit 100 is affected by various factors, among which the fan 120 is the main source of noise. However, the fan speed and the noise of the refrigeration and freezing unit 100 are not positively correlated; that is, a lower fan speed does not necessarily mean lower noise. Since the fan 120 has the lowest noise level when running at the first preset fan speed, when the actual ambient temperature is less than or equal to the preset ambient temperature, executing the fan speed with the lowest noise level can further improve the noise reduction effect.

[0063] Furthermore, the speed of the first compressor can be set according to the speed of the first fan. That is to say, the compressor speed is related to the fan speed; generally, when the fan speed is low, the compressor speed is also low, and vice versa.

[0064] In some optional embodiments of the present invention, in step S201, the first compressor speed is the compressor speed with the lowest noise level when only the compressor 110 is running in the refrigeration and freezing unit 100, wherein the first compressor speed is within the rated compressor speed range. The first fan speed is the fan speed with the lowest noise level when only the fan 120 is running in the refrigeration and freezing unit 100, wherein the first fan speed is within the rated fan speed range. When the actual ambient temperature is ≤ the preset ambient temperature, executing the fan speed and compressor speed with the lowest corresponding noise level can further improve the noise reduction effect.

[0065] like Figure 3 As shown, in some optional embodiments of the present invention, the control method for the air conditioner further includes the following steps:

[0066] S300, obtains the room temperature of each compartment;

[0067] S400: Determine whether the greenhouse chamber meets the exit conditions for silent mode; if not, proceed to S200; if yes, proceed to S500.

[0068] S500, exit silent mode and control compressor 110 to execute the third compressor speed, and / or control fan 120 to execute the third fan speed;

[0069] S600: When the temperature of each compartment is less than or equal to the corresponding second target temperature, determine whether the current time is within a preset quiet period; if yes, proceed to S100; if no, proceed to S500. In some alternative embodiments, if the current time is within a preset quiet period, proceed to step S200.

[0070] Specifically, the second target temperature is equal to or less than the first target temperature. Preferably, the second target temperature is equal to or less than the user-set temperature.

[0071] During the operation of silent mode, if the exit conditions for silent mode are not met, the step of "controlling the speed of compressor 110 and / or fan 120 according to the actual ambient temperature" is executed. During the operation of silent mode, if the exit conditions for silent mode are met, silent mode is exited, and the speed of compressor 110 and / or fan 120 is increased (either in normal mode or other modes) to quickly reduce the compartment temperature and avoid affecting the preservation effect. If the compartment temperature decreases and the current time is still within the preset silent time period, silent mode is executed again to maximize the duration of silent mode operation. Silent mode is not re-entered until the current time is no longer within the preset silent time period. Using the control method of this embodiment, the silent effect and preservation effect can be better balanced within the preset silent time period.

[0072] In some alternative embodiments of the present invention, the exit condition for the silent mode includes: the difference between the room temperature of any room and the corresponding first target temperature is greater than a temperature threshold.

[0073] Preferably, the temperature threshold is between 2°C and 15°C. For example, the temperature threshold can be any one of 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, 11°C, 12°C, 13°C, 14°C, and 15°C.

[0074] More preferably, the first target temperature of each compartment is greater than the corresponding user-set temperature. In some alternative embodiments, the first target temperature is equal to the corresponding set temperature.

[0075] Specifically, the user-set temperature for refrigerator compartment R is 5°C. The user-set temperature for freezer compartment F is -18°C. The user-set temperature for variable temperature compartment S is 7°C.

[0076] like Figure 4As shown, in some optional embodiments of the invention, before step S200, which involves obtaining the actual ambient temperature and controlling the speed of the compressor 110 and / or the fan 120 based on the actual ambient temperature, the following step is also included: S700, determining whether the room temperature is greater than the first target temperature; if not, then proceeding to S100; if yes, then proceeding to S200.

[0077] In this embodiment, after step S100, if the compartment temperature is greater than the first target temperature, then step S200 is executed. If the compartment temperature is less than or equal to the first target temperature, then step S100 continues. Using this method, the noise reduction effect can be further improved while ensuring the preservation effect.

[0078] In some optional embodiments of the present invention, the preset quiet time period is a pre-set quiet time period within the refrigeration and freezing device 100. The preset quiet time period can be from 22:00 to 6:00 the next day; or, the preset quiet time period can be from 10:00 to 18:00. Multiple quiet time periods can be preset within the refrigeration and freezing device 100, and the user can select one as needed.

[0079] In some optional embodiments of the present invention, the preset silent period is the silent period set by the user through a mobile APP, the cloud, or the control panel of the refrigeration and freezing device 100. Users can set the desired silent period as needed; that is, the start time and duration of the silent mode can be customized according to user requirements.

[0080] like Figure 5 As shown, in a preferred embodiment of the present invention, the control method of the refrigeration and freezing apparatus 100 includes the following steps:

[0081] S1 receives a signal that the refrigeration and freezing unit meets the start-up conditions for silent mode.

[0082] S2 controls the compressor and fan to stop; after a preset time, S3 is executed.

[0083] S3, obtain the temperature of each compartment.

[0084] S4, determine whether the room temperature is greater than the first target temperature; if yes, execute S5; if no, execute S2; where the first target temperature is greater than the user-set temperature.

[0085] S5, obtain the actual ambient temperature.

[0086] S6, if the actual ambient temperature is less than or equal to the preset ambient temperature, control the compressor to execute the first compressor speed and control the fan to execute the first fan speed; wherein, the first compressor speed is the compressor speed with the lowest noise level when only the compressor is running, and the first compressor speed is within the rated compressor speed range. The first fan speed is the fan speed with the lowest noise level when only the fan is running, and the first fan speed is within the rated fan speed range.

[0087] S7, if the actual ambient temperature is greater than the preset ambient temperature, control the compressor to run at the second compressor speed and control the fan to run at the second fan speed. Wherein, the second compressor speed is greater than the first compressor speed, and the second fan speed is greater than the first fan speed.

[0088] S8, determine whether the greenhouse chamber meets the exit conditions for silent mode; if yes, execute S9; if no, execute S5.

[0089] S9 exits silent mode and controls the compressor to run at the third compressor speed and the fan to run at the third fan speed. The third compressor speed is greater than the second compressor speed, and the third fan speed is greater than the second fan speed.

[0090] S10: When the temperature of each room is less than or equal to the corresponding second target temperature, determine whether the current time is within the preset silent period; if yes, execute S2; if no, execute S9. The second target temperature is less than or equal to the first target temperature.

[0091] The control method of this embodiment can significantly improve the noise reduction effect and effective noise reduction time; on the other hand, it can also effectively maintain the preservation effect.

[0092] 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.
