[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0044] Although existing smart refrigerators can automatically adjust to quick cooling mode or deep cooling mode according to temperature changes, this automatic adjustment does not always meet the actual needs of users. For example, when the deep cooling state is automatically entered in the smart mode, it is not what the user actually needs, resulting in unnecessary energy waste. In addition, in the deep cooling mode, the compressor and fan run at the highest speed, which not only produces high noise, but also increases energy consumption, which has a negative impact on the user's daily life.

[0045] In order to meet the user's usage habits and needs and reduce energy waste, the embodiment of the present application provides a refrigerator and its control method, device and storage medium, which will be described below in conjunction with the accompanying drawings.

[0046] See also Figure 1 , Figure 1 A first flow chart of a refrigerator control method provided in an embodiment of the present application. The refrigerator control method in an embodiment of the present application includes:

[0047] Step S110: receiving a user's work mode selection instruction.

[0048] In the existing deep freezing mode, the freezer compartment is controlled at -40 degrees, and the compressor and fan run at the highest speed, resulting in excessive energy consumption. High-speed compressors and fans will generate high noise when running, affecting the daily life of users. When the deep freezing mode or deep freezing state is automatically entered in the smart mode, it is often not actually needed by the user, and food may be damaged due to overcooling.

[0049] Based on the above problems, the embodiment of the present application uses the user's selection instruction as the priority condition for determining the refrigerator working mode, thereby ensuring that the deep freezing mode is based on the user's clear needs and reducing energy waste.

[0050] For example, users can manually select through the refrigerator display panel or remotely set through the mobile phone APP (application), such as setting the refrigerator's working mode to deep freezing mode, which has priority over entering the quick cooling mode and deep freezing mode through the smart mode. When the user actively selects the deep freezing mode working mode, the refrigerator is controlled according to the actual deep freezing control, that is, the target temperature of the freezer compartment is -40℃, and the compressor and fan are both running at the highest speed.

[0051] Among them, if the user does not operate the refrigerator within the set time, the user's selection instruction will be set to smart mode by default to facilitate the intelligent operation of the refrigerator and improve user satisfaction.

[0052] Step S120: If it is determined according to the selection instruction that the working mode of the refrigerator is the intelligent mode, the temperature change rate of the freezing compartment is obtained.

[0053] There are at least two ways to determine that the working mode of the refrigerator is the smart mode according to the selection instruction. One is based on the user's touch operation on the refrigerator display panel, or based on the remote setting of the user's mobile phone APP; the other is that the user does not operate the refrigerator and it automatically enters the smart mode.

[0054] In the intelligent mode, the temperature change rate of the freezer compartment is obtained, for example, by cooperating with a temperature sensor and a timer to realize recording of temperature changes within a set time period to monitor the working status of the freezer compartment.

[0055] It should be noted that in the smart mode, the temperature of the freezer compartment can be obtained in real time to prevent the temperature of the freezer compartment from rising suddenly and causing food spoilage.

[0056] Step S130: When the temperature change rate exceeds a set first threshold, the operating mode is switched to a deep cooling mode.

[0057] In the smart mode, when the temperature change rate of the freezer compartment exceeds the set first threshold, for example, the first threshold is 1°C / minute. For example, the temperature of the freezer compartment rises by 15°C within 15 minutes. At this time, the user may forget to close the freezer compartment door, so the freezer compartment needs to be quickly cooled. At this time, the working mode of the refrigerator can be switched to the deep freezing mode, that is, the system automatically enters the deep freezing mode to achieve the purpose of lowering the temperature of the freezer compartment.

[0058] Step S140: In deep cooling mode, the fan is controlled to operate at a first speed which is less than a preset maximum fan speed; and / or the compressor is controlled to operate at a step speed, wherein the speed value in the step speed is less than a preset maximum compressor speed.

[0059] The deep freezing function entered in the smart mode is not an active choice by the user, but is intended to lower the temperature of the freezer compartment. If the actual deep freezing control is used, that is, the target temperature is -40°C, the compressor and fan will both run at the highest speed, which will cause high noise and high energy consumption, affecting the user experience.

[0060] In order to reduce the occurrence of the above problems, the embodiment of the present application controls the fan and / or compressor to operate at different maximum speeds. In addition, the target temperature of the freezing chamber is not the target temperature in the deep freezing mode, i.e. -40°C, but operates according to the target temperature set by the user to reduce the risk of food being damaged by overcooling.

[0061] For example, the fan is controlled to operate at a first speed which is less than a preset maximum fan speed. The first speed may be, for example, 60% of the preset maximum fan speed. This ensures that cold air is continuously blown in without generating loud noise.

[0062] For another example, the compressor is controlled to operate at a stepped speed, and the speed value in the stepped speed is less than the preset maximum speed of the compressor. The stepped speed can be understood as a speed control scheme in which the speed of the compressor decreases or increases in a stepwise manner. Compared with directly reducing or increasing the speed of the compressor, the stepped speed control scheme of the embodiment of the present application can make the operation of the compressor more stable and can further reduce the noise of the compressor. In addition, the speed of the compressor operating at a stepped speed can be set based on the temperature of the freezer compartment, which conforms to the law of temperature change in the freezer compartment and can further save energy consumption.

[0063] In the control method of the refrigerator in the embodiment of the present application, by setting the opening of the deep freezing mode to user selection priority, and controlling the fan and the compressor to operate at a speed less than the maximum speed when entering the deep freezing mode in the intelligent mode, the refrigeration effect of the refrigerator is met and the noise is reduced, which can meet the user's needs and reduce energy waste.

[0064] The reception of the user's working mode selection instruction can be achieved by, for example, receiving a touch pressing signal of the user operating the refrigerator display panel, or by receiving a communication signal between the refrigerator and an external device such as a mobile phone. Figure 1 Also see Figure 2 As shown, Figure 2 A second flow chart of the refrigerator control method provided in an embodiment of the present application. In one implementation, step S110, receiving a user's operating mode selection instruction, includes:

[0065] Step S111: obtaining a pressing signal of a touch button on a display panel of the refrigerator.

[0066] Step S112: Acquire the communication signal between the external device and the refrigerator.

[0067] Step S113: When a pressing signal or a communication signal is received, determining that the working mode of the refrigerator is the working mode corresponding to the pressing signal or the communication signal.

[0068] Regarding steps S111 to S113:

[0069] The display panel of the refrigerator is usually equipped with touch keys or buttons. By obtaining the pressing signal of the touch keys or buttons, the user's selection instructions for the refrigerator working mode can be learned. Touch keys in different positions correspond to different functions. For example, for the working mode, the quick cooling mode, deep cooling mode and smart mode can have corresponding touch keys respectively. By obtaining the position of the touch key corresponding to the pressing signal, the working mode selected by the user can be obtained according to the mapping relationship.

[0070] With the advancement of intelligent technology, there are more and more interactive functions between household appliances and mobile devices such as mobile phones. For example, the working mode of the refrigerator can be set through the mobile phone APP (application software), so that the refrigerator can be remotely controlled. Correspondingly, there are different touch buttons corresponding to different working modes in the mobile phone APP. The communication signal corresponding to the touch button selected by the user can be transmitted to the refrigerator to realize the selection of the refrigerator working mode.

[0071] Exemplarily, when a pressing signal or a communication signal is received, the working mode of the refrigerator is determined to be the working mode corresponding to the pressing signal or the communication signal. For example, when a user selects a touch button corresponding to the deep freezing mode through the refrigerator display panel, the working mode of the refrigerator is determined to be the deep freezing mode corresponding to the pressing signal.

[0072] Among them, if a press signal and a communication signal are received at the same time, and the working modes of the refrigerator corresponding to the press signal and the communication signal are different, the refrigerator can be operated according to the working mode of the refrigerator corresponding to the communication signal. This is because, from experience, users who usually use mobile phone APPs are not the elderly or children, and they have a clearer understanding of the operating procedures or instructions of the refrigerator. Therefore, they can control the refrigerator more flexibly and accurately, and are also the main object of refrigerator usage satisfaction.

[0073] Step S114: When no pressing signal or communication signal is received within a preset time period, it is determined that the working mode of the refrigerator is the smart mode.

[0074] It should be noted that if the working mode of the refrigerator always waits for the user's operation to start, it will affect the refrigerator's performance in preserving food. Therefore, when no press signal or communication signal is received within the preset time, it indicates that the user has not selected the refrigerator mode within the preset time, or has not stored new food in the refrigerator. At this time, the working mode of the refrigerator can be set to the smart mode to flexibly monitor the operation of the refrigerator and improve the intelligence of the refrigerator operation.

[0075] Among them, the preset time length can be, for example, 20 minutes. During the preset time length, the working mode of the refrigerator can be the working mode set last time, or it can be the set refrigerator initialization or normal operation mode, so as to take into account both energy saving and preservation performance.

[0076] When switching from the intelligent mode to the deep cooling mode, there can be multiple combinations of controlling the speed of the fan and the compressor. In one implementation, step S140, in the deep cooling mode, controls the fan to operate at a first speed, the first speed is less than the preset maximum speed of the fan; and / or controls the compressor to operate at a step speed, the speed value in the step speed is less than the preset maximum speed of the compressor, including:

[0077] Step S141: in the deep cooling mode, after controlling the compressor to operate at the second speed for a first period of time, the speed of the compressor is adjusted to a third speed, where the third speed is lower than the second speed.

[0078] The second speed and the third speed are both lower than the set maximum speed of the compressor, and the third speed is lower than the second speed. For example, the second speed may be 75% of the maximum speed of the compressor, and the third speed may be 50% of the maximum speed of the compressor.

[0079] That is to say, in the embodiment of the present application, the stepped speed includes a second speed and a third speed. After the second speed is operated for a first period of time, which may be 10 minutes, the speed of the compressor is adjusted to the third speed and continues to run. The stepped speed operation can reduce the noise of the compressor and save energy on the one hand, and can also steadily reduce the temperature of the freezer compartment on the other hand, thereby reducing the damage to food caused by quick freezing.

[0080] The step speed is not limited to the above-mentioned second speed and third speed. In another implementation, step S140, in the deep cooling mode, controls the fan to operate at a first speed, the first speed is less than the preset maximum speed of the fan; and / or controls the compressor to operate at a step speed, the speed value in the step speed is less than the preset maximum speed of the compressor, including:

[0081] Step S142: in the deep cooling mode, after controlling the compressor to operate at the second speed for a first period of time, the second speed is reduced and operated at a first ratio at intervals of a second period of time until the speed of the compressor is adjusted to a third speed.

[0082] The second speed and the third speed are both less than the set maximum speed of the compressor, and the third speed is less than the second speed. For example, the second speed can be 75% of the maximum speed of the compressor, and the third speed can be 50% of the maximum speed of the compressor. For example, the first duration can be 6 minutes, and the second duration can be 5 minutes.

[0083] In the intelligent mode, the deep freezing mode is entered to obtain the temperature of the freezing compartment at a preset frequency, such as monitoring the temperature once per second, and the target temperature at this time is not -40°C in the deep freezing mode, but the temperature of the freezing compartment set by the user. When the deep freezing mode is just entered, the compressor speed is the second speed, that is, 75% of the maximum speed of the compressor, and runs for 6 minutes. After that, the compressor speed is reduced by 5% of the maximum speed of the compressor every 5 minutes until it is reduced to the third speed, that is, 50% of the maximum speed of the compressor.

[0084] The compressor speed can be reduced in a step-by-step manner to reduce abnormal noise caused by rapid downshifting of the compressor, and can be controlled according to the real-time temperature of the freezer compartment, in line with the temperature change law of the freezer compartment, thereby improving the user experience.

[0085] See also Figure 3 As shown, Figure 3A third flow chart of the refrigerator control method provided by the embodiment of the present application. For exiting the deep freezing mode, the temperature of the freezer compartment can be used as a judgment condition. In one implementation, step S140, in the deep freezing mode, controls the fan to operate at a first speed, the first speed is less than the preset maximum fan speed; and / or controls the compressor to operate at a step speed, the speed value in the step speed is less than the preset maximum compressor speed, and then the refrigerator control method further includes:

[0086] Step S150: Obtain the set temperature of the freezing compartment set by the user.

[0087] Step S160: determining the set temperature as the target temperature of the freezing compartment in the deep freezing mode.

[0088] Regarding step S150 and step S160:

[0089] Entering deep freezing mode in smart mode is often due to the need for refrigeration in the freezer compartment. If it is operated at the original temperature of the deep freezing mode, such as -40°C, not only will the compressor and fan run at the highest speed, causing noise problems, but it may also cause food to freeze and increase energy consumption.

[0090] Based on this, the embodiment of the present application uses the set temperature of the freezing compartment set by the user as the target temperature for entering the deep freezing mode in the intelligent mode to meet the user's needs and reduce energy consumption.

[0091] Step S170: When the temperature of the freezing compartment reaches the target temperature, the fan and the compressor are controlled to continue running at the current speed for a set time and then stop.

[0092] Step S180, exit the deep cooling mode and continue to run in the intelligent mode.

[0093] Regarding step S170 and step S180:

[0094] The end judgment condition of the deep freezing mode in the intelligent mode can be the temperature of the freezer compartment, that is, when the temperature of the freezer compartment reaches the target temperature, the deep freezing mode can be exited. However, considering the constancy of the temperature of the freezer compartment, or in order to reduce the large fluctuations in the temperature of the freezer compartment, the fan and the compressor can be controlled to continue running at the current speed for a set time, such as stopping after 5 minutes. In addition, the shutdown of both the fan and the compressor can also serve as a sign of the transition from the deep freezing mode to the intelligent mode. Among them, in order to reduce the vibration problem caused by the asynchronous shutdown of the fan and the compressor, the fan can be controlled to stop before the compressor.

[0095] In the control method of the refrigerator provided in the embodiment of the present application, the deep freezing mode is entered in the intelligent mode, and the rotation speeds of the compressor and the fan are adjusted so that the rotation speeds are within a reasonable range, thereby ensuring the refrigeration effect of the refrigerator, reducing noise, and reducing energy consumption.

[0096] In order to better implement the refrigerator control method of the embodiment of the present application, the embodiment of the present application also provides a refrigerator control device. Figure 4 As shown, Figure 4 The control device 400 of the refrigerator includes a receiving unit 410 , an acquiring unit 420 , a switching unit 430 , and a control unit 440 .

[0097] The receiving unit 410 is used to receive a user's operating mode selection instruction.

[0098] The acquisition unit 420 is used to acquire the temperature change rate of the freezer compartment if it is determined according to the selection instruction that the working mode of the refrigerator is the smart mode.

[0099] The switching unit 430 is used to switch the working mode to the deep cooling mode when the temperature change rate exceeds a set first threshold.

[0100] The control unit 440 is used to control the fan to operate at a first speed in the deep cooling mode, the first speed being less than the preset maximum fan speed; and / or control the compressor to operate at a step speed, the speed value in the step speed being less than the preset maximum compressor speed.

[0101] All of the above technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described in detail here.

[0102] In the control device 400 of the refrigerator provided in the embodiment of the present application, by setting the opening of the deep freezing mode to user selection priority, and controlling the fan and the compressor to operate at a speed less than the maximum speed when entering the deep freezing mode in the intelligent mode, the refrigeration effect of the refrigerator is met and the noise is reduced, which can meet the user's needs and reduce energy waste.
