Description

Refrigeration and freezing device, control method thereof, and machine readable storage medium

[0001] The present application claims priority to the Chinese patent application with the application date of September 29, 2024, the application number of 202411375772.3, and the invention name of "Refrigeration and freezing device, control method thereof, and machine readable storage medium", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of refrigeration technology, in particular to a refrigeration and freezing device, a control method thereof, and a machine readable storage medium. BACKGROUND

[0003] At present, the operation modes of the refrigeration and freezing device include normal mode, silent mode and defrosting mode. The silent mode of the refrigeration and freezing device mainly reduces noise by reducing the rotation speed of the compressor and / or the rotation speed of the fan, so as to improve the quietness of the use environment. However, due to the low rotation speed of the compressor, the refrigerating capacity of the refrigeration system is reduced, which leads to the decrease of the evaporation pressure and the evaporation temperature. The low rotation speed of the fan leads to insufficient air supply, which further leads to insufficient heat exchange of the evaporator, and reduces the evaporation pressure and the evaporation temperature. This leads to a high probability of frost formation on the surface of the evaporator when the refrigeration and freezing device operates in the silent mode. If the silent mode is operated for a long time, the surface of the evaporator may be seriously frosted, which affects the refrigeration efficiency of the refrigeration and freezing device; and even leads to the blockage of the drain due to the icing of the condensed water, which affects the normal operation of the refrigeration and freezing device and reduces the user experience.

[0042] The present application will be described in detail below with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and any changes in structure, method, or function made by those of ordinary skill in the art based on these embodiments are included within the scope of protection of the present application.

[0043] The refrigeration and freezing device, the control method of the refrigeration and freezing device, and the machine readable storage medium according to the embodiments of the present application will be described below with reference to FIGS. 1 to 7.

[0044] FIG. 1 is a schematic flowchart of the control method of the refrigeration and freezing device 100 according to an embodiment of the present application. As shown in FIG. 1, the present application provides a control method of the refrigeration and freezing device 100, which can include the following steps:

[0045] S100, in response to the start instruction of the mute mode, acquiring a current operation mode of the refrigerator-freezer 100;

[0046] S200, if the refrigerator-freezer 100 is currently in the normal mode, executing a corresponding preset control strategy to determine whether to defrost before entering the mute mode for the first time and / or after exiting a preset mute time period.

[0047] In an embodiment, the start instruction of the mute mode can be a mute mode start instruction sent by a user. The start instruction of the mute mode can also be a mute mode start instruction automatically sent by the controller when the current time reaches the start time of the preset mute time period, which is set by the user in advance or at the factory. The mute mode can be run all the time within the preset mute time period. When the temperature of any chamber is greater than or equal to an exit temperature within the preset mute time period, the mute mode is exited and the normal mode is entered. When the chamber temperature decreases and the mute time period is still within the preset mute time period, the mute mode is entered again. The start point of the preset mute time period refers to the time point of entering the mute mode for the first time. The difference between the end point and the start point of the preset mute time period is a preset mute duration. The preset mute duration can be set by the user or set at the factory.

[0048] In the embodiment, when the refrigerator-freezer 100 receives the start instruction of the mute mode, the current operation mode of the refrigerator-freezer 100 is first acquired. If the refrigerator-freezer 100 is currently in the normal mode, a corresponding preset control strategy is executed to determine whether to defrost before the mute mode is run, or after the mute mode is completely exited, or both before the mute mode is run and after the mute mode is completely exited.

[0049] On the one hand, no defrosting is performed within the preset mute time period, which can avoid noise generated by defrosting from affecting the mute effect. On the other hand, whether defrosting is needed is determined before entering the mute mode for the first time and / or after the mute mode is completely exited. If defrosting is needed, corresponding defrosting operations are performed before entering the mute mode for the first time and / or after the mute mode is completely exited, which can avoid the evaporator from being heavily frosted after the mute mode is ended, thereby affecting the subsequent normal mode operation, and achieve the purpose of improving the user experience.

[0050] As shown in FIG. 2, in some optional embodiments of the present application, the preset control strategy includes a first preset control strategy. In S200, the execution of the preset control strategy to determine whether to defrost before entering the mute mode for the first time and / or after exiting the corresponding preset mute time period includes S210, execution of the first preset control strategy.

[0051] The first preset control strategy may include: S211, determining whether the first defrosting condition is met, and determining whether to defrost before entering silent mode for the first time based on the determination result.

[0052] In this embodiment, when the refrigerator / freezer 100 receives a start command for silent mode, it acquires the current operating mode of the refrigerator / freezer 100. If the refrigerator / freezer 100 is currently in normal mode, a first control strategy is executed: before entering silent mode for the first time, it is determined whether a first defrosting condition is met; based on the determination result, it is determined whether defrosting should be performed before entering silent mode for the first time. If the first defrosting condition is met, defrosting can be performed before entering silent mode for the first time.

[0053] The method of this embodiment can prevent severe frosting of the evaporator during silent mode operation, improve the heat exchange performance of the evaporator, and prevent the drain outlet from being blocked by condensate freezing. Furthermore, it avoids frequent exits from silent mode due to poor heat exchange performance of the evaporator during the preset silent time period; that is, this embodiment can extend the actual operating time of silent mode, thereby giving the refrigeration and freezing device 100 a better silent effect.

[0054] In some optional embodiments of this application, the first defrosting condition includes: the amount of frost on the evaporator is greater than or equal to a first preset frost amount. In one embodiment, the amount of frost on the evaporator surface is acquired using a camera probe. The camera probe can be a video camera or an infrared camera.

[0055] In some optional embodiments of this application, the first defrosting condition includes: a first time interval greater than or equal to a first preset duration. The first time interval is: the time interval between receiving the silent mode activation command and the last defrost.

[0056] In this embodiment, the first preset duration can be set according to the specific model of the refrigeration and freezing device 100. Optionally, the first preset duration can be 8~10h (e.g., 8h, 8.5h, 9h, 9.5h, or 10h). Compared with the previous embodiment, this embodiment does not require additional frost amount detection equipment, thereby saving equipment production costs.

[0057] In some optional embodiments of this application, the first defrosting condition includes: a first time interval greater than or equal to a first preset duration; and the amount of frost on the evaporator greater than or equal to a first set amount of frost. Using the above two conditions as the first defrosting condition can reduce misjudgments and thus improve control accuracy.

[0058] As shown in Figure 2, in some optional embodiments of this application, step S211, which involves determining whether to defrost before entering silent mode based on the judgment result, may include the following steps:

[0059] S2111, if the first defrosting condition is met, entering a first defrosting mode;

[0060] After the first defrosting mode ends, entering a mute mode; or, after the first defrosting mode ends, entering a normal mode, and when the chamber temperature of each chamber reaches the corresponding set temperature, exiting the normal mode and entering the mute mode;

[0061] S2112, if the first defrosting condition is not met, entering the mute mode.

[0062] In an embodiment, after the first defrosting mode ends, the mute mode can be directly entered; or, the normal mode can be run first to pre-cool each chamber, and then the mute mode is entered. Compared with the above two modes, the second mode can avoid affecting the freezing and refrigerating effect when directly entering the mute mode after defrosting, so as to better ensure the fresh-keeping effect of the freezing and refrigerating device on food, and further better balance the mute effect and the freezing and refrigerating effect.

[0063] As shown in FIG. 3, in some optional embodiments of the present application, after step S2112, the control method further includes the following step: S212, in response to exiting the preset mute time period, judging whether a second defrosting condition is met, and determining whether to defrost before entering the normal mode according to the judgment result.

[0064] In an embodiment, if the first defrosting condition is not met, the mute mode is directly entered, and whether to defrost is confirmed again when the mute mode is completely exited. If the second defrosting condition is met, it is indicated that the evaporator surface may be seriously frosted after the mute mode is completely exited, and the defrosting operation is performed before entering the normal mode, so as to avoid affecting the heat exchange effect of the subsequent normal mode.

[0065] As shown in FIG. 4, in some optional embodiments of the present application, in step S200, the preset control strategy is executed to determine whether to defrost before entering the mute mode for the first time and / or after exiting the corresponding preset mute time period, including: S220, executing a second preset control strategy.

[0066] The second preset control strategy includes: S221, entering the mute mode; S222, in response to exiting the preset mute time period, judging whether the second defrosting condition is met, and determining whether to defrost before entering the normal mode according to the judgment result.

[0067] In an embodiment, when the refrigerator-freezer 100 receives the start instruction of the silent mode, the current operation mode of the refrigerator-freezer 100 is acquired; if the refrigerator-freezer 100 is currently in the normal mode, a second preset control strategy is executed: directly entering the silent mode, and confirming whether the second defrosting condition is met when completely exiting the silent mode; if the second defrosting condition is met, it means that the surface of the evaporator may be seriously frosted after completely exiting the silent mode, and a defrosting operation is performed before entering the normal mode to avoid affecting the heat exchange effect of the subsequent normal mode.

[0068] In some optional embodiments of the present application, the second defrosting condition can include at least one of the following conditions:

[0069] The actual running duration of the silent mode is greater than or equal to a second preset duration;

[0070] The second time interval is greater than or equal to a third preset duration; wherein the second time interval is the time interval from the time when the preset silent period is exited to the last defrosting time;

[0071] The frosting amount of the evaporator is greater than or equal to a second set frosting amount.

[0072] In an embodiment, when at least one of the above conditions is met, the second defrosting condition is met. The second set frosting amount is greater than the first preset frosting amount. The second preset duration can be set according to the model of the refrigerator-freezer 100; optionally, the second preset duration can be 3-5h (for example: 3h, 3.5h, 4h, 4.5h or 5h); preferably, the second preset duration is 4h. The third preset duration is greater than the first preset duration.

[0073] As described in FIG. 3 and FIG. 4, in some optional embodiments of the present application, the determination of whether to defrost before entering the normal mode according to the judgment result includes:

[0074] S241, if the second defrosting condition is met, enter the second defrosting mode, and after exiting the second defrosting mode, enter the normal mode;

[0075] S242, if the second defrosting condition is not met, enter the normal mode.

[0076] The second defrosting mode is a pre-cooling defrosting mode or a non-pre-cooling defrosting mode. Preferably, the second defrosting mode is a pre-cooling defrosting mode; the pre-cooling defrosting mode refers to: controlling the compressor 110 to operate until the temperature of each compartment decreases by a preset temperature, and then the compressor 110 stops and the defrosting heating wire starts. The effect of pre-cooling defrosting is to avoid the high temperature of the compartment caused by direct defrosting. Compared with non-pre-cooling defrosting, pre-cooling defrosting is beneficial to the preservation effect of food.

[0077] As shown in FIG. 5, in some optional embodiments of the present application, after step S100, the control method further comprises: S300, if the refrigerating-freezing device 100 is currently in the third defrosting mode, after the third defrosting mode ends, the compressor 110 is controlled to operate at the first compressor rotation speed; and / or the fan 120 is controlled to execute the first fan 120 rotation speed to enter the mute mode.

[0078] In the present embodiment, when the refrigerating-freezing device 100 receives the starting instruction of the mute mode, the current operation mode of the refrigerating-freezing device 100 is acquired; if the refrigerating-freezing device 100 is currently in the defrosting mode, after the defrosting ends, the mute mode is entered for the first time, and the compressor 110 and / or the fan 120 are controlled to start at a smaller rotation speed to ensure the preservation effect of the freezing and refrigerating compartments.

[0079] In some alternative embodiments, in S300, after the defrosting ends, the compressor 110 and / or the fan 120 are controlled to stop to enter the mute mode for the first time.

[0080] In some optional embodiments of the present application, the refrigerating-freezing device 100 can be a refrigerator, a beverage refrigerating cabinet, a fresh food cabinet, a refrigerator or the like.

[0081] In some optional embodiments of the present application, in step S200, within the preset mute time period, the specific control method of the refrigerating-freezing device can comprise the following steps:

[0082] S510, the refrigeration load is controlled to be turned off to enter the mute mode;

[0083] S520, after the refrigeration load is turned off for a preset time length, the compartment temperature of each compartment is acquired to obtain a first temperature;

[0084] S530, according to the on-off points of the preset gears of each compartment and the first temperature, the refrigeration load is controlled to start and stop.

[0085] In an embodiment, the refrigeration load comprises the compressor 110, the fan 120, the damper and the electromagnetic valve. The on-off points of the preset gears of each compartment refer to the on-off temperatures corresponding to the preset gears of each compartment. When the first temperature of any one compartment is greater than or equal to the corresponding on-off point, the refrigeration load is controlled to be turned on to reduce the temperature of the corresponding compartment; otherwise, when the first temperature of each compartment is less than the corresponding on-off point, the refrigeration load is controlled to continue to be turned off to maintain the mute effect. The preset time length can be set according to needs, and preferably, the preset time length can be 10 min to 3 h, for example, 10 min, 20 min, 0.5 h, 1 h, 2 h, 2.5 h or 3 h.

[0086] After the embodiment enters the mute mode, the refrigeration load is first controlled to be closed to reduce noise; after the refrigeration load is closed for a preset time, the refrigeration load is controlled to be started and stopped according to the on-off points of the preset gears of each compartment, so that the mute effect can be maintained as much as possible, and the preservation effect can be considered in the mute mode. Compared with the prior art, the mute effect of the mute mode can be significantly improved, and the purpose of improving the user experience is achieved.

[0087] In some optional embodiments of the present application, the refrigeration-freezing device 100 comprises compartments. The number of compartments in the refrigeration-freezing device 100 is one or two or three or four or more than four. Preferably, the refrigeration-freezing device 100 comprises a refrigeration compartment R, a freezing compartment F and a variable-temperature compartment S.

[0088] In some optional embodiments of the present application, S530, the starting and stopping of the refrigeration load is controlled according to the on-off points of the preset gears of each compartment and the first temperature, comprising the following steps:

[0089] S531, whether the starting condition of the refrigeration load is met is judged according to the on-off points of the preset gears of each compartment and the first temperature; if yes, S532 is executed; if no, S510 is executed;

[0090] S532, the refrigeration load is controlled to be started;

[0091] S533, the actual ambient temperature is obtained;

[0092] S534, if the actual ambient temperature is less than or equal to the preset ambient temperature, the compressor 110 is controlled to execute the third compressor speed, and / or the fan 120 is controlled to execute the third fan speed.

[0093] S535, if the actual ambient temperature is greater than the preset ambient temperature, the compressor 110 is controlled to execute the fourth compressor speed, and / or the fan 120 is controlled to execute the fourth fan speed.

[0094] Wherein, the fourth compressor speed is greater than the third compressor speed, and the fourth fan speed is greater than the third fan speed.

[0095] In an embodiment, the preset ambient temperature is 20℃ to 45℃, for example, 20℃, 25℃, 30℃, 35℃, 40℃ or 45℃. More preferably, the preset ambient temperature is 32℃. In this embodiment, when the actual ambient temperature is high, a relatively high compressor speed and / or fan speed is used, which can better consider the refrigeration effect while reducing noise.

[0096] In some optional embodiments of the present application, the third compressor speed is a compressor speed corresponding to a minimum noise value of the refrigerator-freezer 100 when only the compressor 110 is running, and the third compressor speed is within the rated compressor speed range. The third fan speed is a fan speed corresponding to a minimum noise value of the refrigerator-freezer 100 when only the fan 120 is running, and the third fan speed is within the rated fan speed range. The third compressor speed is equal to the first compressor speed. The third fan speed is equal to the first fan speed.

[0097] When the actual ambient temperature is less than or equal to the preset ambient temperature, the fan speed corresponding to the minimum noise value and the compressor speed corresponding to the minimum noise value are executed, which can further improve the silence effect.

[0098] In some optional embodiments of the present application, the fourth compressor speed is another compressor speed corresponding to a minimum noise value of the refrigerator-freezer when only the compressor is running, and the fourth compressor speed is within the rated compressor speed range. This embodiment can further improve the noise reduction effect, so that the user has a better silent experience.

[0099] In some optional embodiments of the present application, the fourth fan speed is another fan speed corresponding to a minimum noise value of the refrigerator-freezer when only the fan is running. This embodiment can further improve the noise reduction effect, so that the user has a better silent experience.

[0100] In some optional embodiments of the present application, in step S510, the step of controlling the refrigeration load to be closed specifically includes: controlling the compressor and the fan to stop, the damper to be closed, and the electromagnetic valve to be reset. In step S532, the step of controlling the refrigeration load to be opened specifically includes: controlling the compressor and the fan to start, the damper and the electromagnetic valve to be opened. This embodiment provides a specific method for controlling the refrigeration load to be closed and opened, which has the beneficial effects of simple control program and easy execution.

[0101] In some optional embodiments of the present application, the first compressor speed, the third compressor speed, the fourth compressor speed, the first fan speed, the third fan speed, and the fourth fan speed are preset on the controller of the refrigerator-freezer 100.

[0102] In some optional embodiments of the present application, after step S534 or S535, the control method further includes:

[0103] S537, obtaining the compartment temperature of each compartment to obtain a second temperature;

[0104] S538, determining whether the second temperature satisfies the exit condition of the silent mode; if not, executing S533; if yes, executing S540;

[0105] S540, controlling the refrigerator-freezer to exit the silent mode and run in the normal mode;

[0106] S550, obtaining the chamber temperature of each chamber to obtain a third temperature; when the third temperature of each chamber is less than or equal to the corresponding target temperature, S560 is performed;

[0107] S560, determining whether the current time is within the preset quiet time period; if yes, S510 is performed; if no, S570 is performed.

[0108] S570, controlling the refrigeration-freezing device to continue running in the normal mode.

[0109] In an embodiment, the target temperature of each chamber is equal to or less than the corresponding set temperature. The set temperature refers to the user set temperature.

[0110] During the running of the quiet mode, when the exit condition of the quiet mode is not met, step S533 is performed. When the exit condition of the quiet mode is met, the quiet mode is exited, and the normal mode is performed to quickly reduce the chamber temperature, so as to avoid affecting the preservation effect; if the current time is still within the preset quiet time period after the chamber temperature is reduced, the quiet mode is performed again to increase the actual running time of the quiet mode as much as possible. Until the current time is not within the preset quiet time period, the quiet mode is not entered. By using the control method of the embodiment, the quiet effect and the preservation effect can be better balanced within the preset quiet time period.

[0111] In some optional embodiments of the present application, the exit condition of the quiet mode includes that the second temperature of any chamber is higher than the switching point of the corresponding preset gear by a preset temperature threshold.

[0112] Preferably, the preset temperature threshold is 3-10℃. For example, the preset temperature threshold can be any one of 3℃, 4℃, 5℃, 6℃, 7℃, 8℃, 9℃ and 10℃.
