Description

Technical Field

[0001] The embodiments of the present application relate to the field of home appliance technology, and more specifically, to a refrigerator and a refrigerator control method. Background Art

[0002] A refrigerator is generally constructed with a cold storage compartment, which can be used to store fresh food, such as vegetables, fruits, etc. In order to improve the freshness-keeping effect of the cold storage compartment on food, a humidifying device is provided in the cold storage compartment for humidifying the cold storage compartment.

[0003] Currently, a humidifying device is controlled to release water vapor into the cold storage room at a fixed humidification rate, or a hygrometer is set in the cold storage room, and the humidification rate of the water vapor released into the cold storage room is determined according to the humidity value in the cold storage room detected by the hygrometer, and water vapor is released into the cold storage room at this humidification rate.

[0004] However, a fixed humidification rate may cause the humidification rate of the water vapor released by the humidification device to be too high or too low, resulting in poor accuracy. When the humidification rate of the released water vapor is controlled by a hygrometer, the cost of the refrigerator is increased. Summary of the Invention

[0005] The embodiments of the present application provide a refrigerator and a refrigerator control method, which can improve the accuracy of the humidification rate of water vapor released into the refrigeration chamber without increasing the hardware cost of the refrigerator.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] The box body is constructed with a refrigeration chamber;

[0008] a door body connected to the box body;

[0009] a humidifying device, disposed on the door body, the humidifying device being configured with an outlet for diffusing water vapor in the humidifying device into the refrigerating chamber;

[0010] The humidifying device comprises:

[0011] Humidification water box, used to store water;

[0012] A humidifying component, used for converting the water in the humidifying water box into water vapor;

[0013] A compressor is disposed in the box;

[0014] The controller is disposed in the box and is configured to:

[0015] When it is determined that the humidifying device is needed to humidify the refrigerating chamber, obtaining the operating rate of the compressor;

[0016] determining a control parameter according to the startup rate of the compressor;

[0017] According to the control parameter, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber, wherein the startup rate is proportional to the humidification rate corresponding to the control parameter.

[0018] In this application, considering that the humidity in the refrigerator compartment is related to the compressor's operating rate, when a humidifier is needed to humidify the refrigerator compartment, the humidifier can be controlled based on the compressor's operating rate. This eliminates the need for additional hardware in the refrigerator compartment, meaning that the hardware cost of the refrigerator does not increase. Furthermore, by controlling the humidification of the refrigerator compartment based on the compressor's operating rate, the humidification rate of water vapor diffusing into the refrigerator compartment more closely matches the refrigerator's moisture requirements, resulting in higher accuracy.

[0019] In some embodiments of the present application, the humidification component includes:

[0020] a fan, configured to generate an airflow to convert the water in the humidification water box into water vapor, and diffuse the water vapor into the refrigerated compartment through the outlet; the startup rate is proportional to the rotation speed of the fan, and the rotation speed of the fan is proportional to the humidification rate corresponding to the control parameter;

[0021] Alternatively, a heating element is used to heat the water in the humidification water box so that the water in the humidification water box is converted into water vapor; the startup rate is proportional to the power of the heating element, and the power of the heating element is proportional to the humidification rate corresponding to the control parameter;

[0022] Or, an ultrasonic device is used to use ultrasonic vibrations to break up the water in the humidification water box into tiny water droplets to form water vapor; the startup rate is proportional to the power of the ultrasonic device, and the power of the ultrasonic device is proportional to the humidification rate corresponding to the control parameter.

[0023] In the present application, when the humidification component includes any one of a fan, a heating element, and an ultrasonic device, different fan speeds, or different heating element powers, or different ultrasonic device powers are determined according to different compressor start-up rates to control the humidification device to diffuse water vapor into the refrigerated compartment at a corresponding humidification rate.

[0024] In some embodiments of the present application, the humidification component includes any two of a fan, a heating element, and an ultrasonic device;

[0025] The fan is used to generate airflow to accelerate the conversion of water in the humidification water box into water vapor, and diffuse the water vapor into the refrigerated compartment through the outlet; the startup rate is proportional to the speed of the fan, and the speed of the fan is proportional to the humidification rate corresponding to the control parameter;

[0026] The heating element is used to heat the water in the humidification water box so that the water in the humidification water box is converted into water vapor; the power-on rate is proportional to the power of the heating element, and the power of the heating element is proportional to the humidification rate corresponding to the control parameter;

[0027] The ultrasonic device is used to use ultrasonic vibrations to break up the water in the humidification water box into tiny water droplets to form water vapor; the startup rate is proportional to the power of the ultrasonic device, and the power of the ultrasonic device is proportional to the humidification rate corresponding to the control parameter;

[0028] The control parameters include a first control parameter;

[0029] The controller is configured to:

[0030] When the on-rate is less than a first preset on-rate, determining a first control parameter according to the on-rate of the compressor;

[0031] According to the first control parameter, one of the two humidifying components is controlled to operate so that the water in the humidifying water box is converted into water vapor and diffused into the refrigerating chamber.

[0032] In the present application, when the startup rate is low, the demand for water vapor in the refrigeration chamber is low. Therefore, one of the two humidification components can be controlled to operate, which can reduce the waste of unnecessary resources.

[0033] In some embodiments of the present application, the control parameter includes a second control parameter;

[0034] The controller is configured to:

[0035] When the on-rate is greater than or equal to the first preset on-rate, determining a second control parameter according to the on-rate of the compressor;

[0036] According to the second control parameter, both humidification components are controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber; the humidification rate corresponding to the second control parameter is greater than the humidification rate corresponding to the first control parameter.

[0037] In the present application, when the startup rate is high, the demand for water vapor in the refrigeration chamber is high. Therefore, the two humidification components can be controlled to run simultaneously, so that the humidification rate is high and the time for humidifying the refrigeration chamber can be shortened.

[0038] In some embodiments of the present application, the humidification component includes:

[0039] a fan, configured to generate an airflow to convert the water in the humidification water box into water vapor, and diffuse the water vapor into the refrigeration chamber through the outlet;

[0040] a heating element, used to heat the water in the humidification water box so that the water in the humidification water box is converted into water vapor;

[0041] An ultrasonic device for breaking up the water in the humidification water box into tiny water droplets using ultrasonic vibrations to form water vapor;

[0042] The control parameters include a third control parameter;

[0043] The controller is configured to:

[0044] Determining, based on the startup rate and the first corresponding relationship, N humidifying components that need to be operated corresponding to the startup rate, and the third control parameter corresponding to the N humidifying components; the first corresponding relationship is the startup rate, the target humidifying component to be operated, and the control parameter corresponding to the target humidifying component; N is one of 1, 2, and 3, and is proportional to the startup rate;

[0045] According to the third control parameter, the target humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber; the humidification rate corresponding to the third control parameter is proportional to N.

[0046] In this application, different numbers of humidifying components are used to diffuse water vapor into the refrigerated compartment based on the power-on rate. This allows for a higher humidification rate when the power-on rate is high, i.e., when the refrigerated compartment has a greater demand for water vapor. A lower humidification rate is used when the power-on rate is low, i.e., when the refrigerated compartment has a lower demand for water vapor. This ensures that the humidification rate of the humidifying device matches the demand for water vapor, resulting in a more accurate control of the humidification device's diffusion of water vapor into the refrigerated compartment.

[0047] In some embodiments of the present application, the controller is further configured to:

[0048] When it is determined that the humidifying device is required to humidify the refrigerating chamber, the ambient temperature and the number of times the door has been opened within a preset operating time before the current moment are obtained;

[0049] determining a control parameter according to the startup rate, the ambient temperature, and the number of times;

[0050] According to the control parameters, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber, wherein the power-on rate, the ambient temperature and the number of times are all proportional to the humidification rate corresponding to the control parameters.

[0051] In this application, while considering the startup rate, the number of times the door is opened during preset operation and the ambient temperature are also considered, so that the humidification rate corresponding to the determined control parameters is more in line with the cold storage room's demand for water vapor, making the control of the cold storage room humidification more accurate.

[0052] In some embodiments of the present application, the humidification component includes at least one of a fan, a heating element, and an ultrasonic device;

[0053] The fan is used to generate airflow to convert the water in the humidification water box into water vapor, and diffuse the water vapor into the refrigeration chamber through the outlet;

[0054] The heating element is used to heat the water in the humidification water box so that the water in the humidification water box is converted into water vapor;

[0055] The ultrasonic device is used to use ultrasonic vibration to break up the water in the humidification water box into tiny water droplets to form water vapor;

[0056] The control parameters include a fourth control parameter;

[0057] The controller is configured to:

[0058] Determining a corresponding fourth control parameter according to the startup rate, the ambient temperature, the number of times, and the second corresponding relationship;

[0059] According to the fourth control parameter, at least one humidifying component is controlled to operate so that the water in the humidifying water box is converted into water vapor and diffused into the refrigerated chamber; the power-on rate, the ambient temperature, and the number of times are proportional to the number of running humidifying components.

[0060] In this application, the demand for water vapor in the refrigerated compartment can be determined based on the compressor's operating rate, ambient temperature, and the number of times the door is opened, thereby determining the operation of the humidifying components that need to be operated. When the demand for water vapor in the refrigerated compartment is high, multiple humidifying components can be determined to operate simultaneously, so that the humidifying components diffuse water vapor into the refrigerated compartment at a high humidification rate. This ensures that the humidification rate corresponding to the determined control parameters matches the demand for water vapor in the refrigerated compartment.

[0061] In some embodiments of the present application, the control parameters further include a fifth control parameter;

[0062] The controller is further configured to:

[0063] When the operating time of the refrigerator is less than the preset operating time, obtaining a fifth control parameter;

[0064] According to the fifth control parameter, the humidifying component is controlled to operate so that the water in the humidifying water box is converted into water vapor and diffused into the refrigerating chamber.

[0065] In the present application, when the operating time of the refrigerator is less than the preset operating time, the default control parameters can be used to control the humidification device to diffuse water vapor into the refrigeration chamber.

[0066] In some embodiments of the present application, the controller is configured to:

[0067] Get the operating status of the compressor;

[0068] When the compressor is in a stopped state, the humidifying component is controlled to operate so that the water in the humidifying water box is converted into water vapor and diffused into the refrigerating chamber.

[0069] In the present application, since the refrigeration system provides cooling to the cold storage room while taking away moisture from the cold storage room during the operation of the compressor, diffusing water vapor into the cold storage room when the compressor is stopped can reduce the situation where moisture is taken away by refrigeration, so that the moisture in the cold storage room can get the required amount as soon as possible.

[0070] In a second aspect, the present application provides a method for controlling a refrigerator, the refrigerator comprising:

[0071] The box body is constructed with a refrigeration chamber;

[0072] a door body connected to the box body;

[0079] When it is determined that the humidifying device is needed to humidify the refrigerating chamber, obtaining the operating rate of the compressor;

[0080] determining a control parameter according to the startup rate of the compressor;

[0081] According to the control parameter, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber, wherein the startup rate is proportional to the humidification rate corresponding to the control parameter.

[0082] In a third aspect, the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores computer-executable instructions, and when the computer-executable instructions are executed by a computer, they are used to implement the method described in the second aspect.

[0083] The computer-readable storage medium provided in the embodiment of the present application can execute the technical solutions in the above method embodiments, and its beneficial effects are similar and will not be repeated here.

[0084] In a fourth aspect, the present application provides a computer program product, comprising a computer program, which is used to implement the method described in the second aspect when executed by a computer.

[0085] The computer program product provided in the embodiment of the present application can execute the technical solutions in the above method embodiments, and its beneficial effects are similar, which will not be described in detail here.

[0099] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0100] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0101] In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0102] The cold storage compartment of a refrigerator is mostly used to store vegetables, fruits, and in order to reduce the loss of water on the surface of the vegetables, fruits, a humidifying device can be installed in the cold storage compartment to humidify the cold storage compartment.

[0103] In some implementations, the humidifier is controlled to release water vapor into the refrigerated compartment at a fixed humidification rate. Specifically, a control parameter for the humidification rate of the released water vapor can be pre-set, and the humidifier is controlled to release water vapor into the refrigerated compartment based on the control parameter.

[0104] However, the demand for water vapor in the refrigeration chamber is not constant, and a fixed humidification rate may cause the amount of water vapor released into the refrigeration chamber to be too large or too small. Therefore, the method of releasing water vapor into the refrigeration chamber at a fixed humidification rate has low accuracy.

[0105] In other implementations, a hygrometer is provided within the refrigerator compartment, and the humidification rate of water vapor released into the refrigerator compartment is controlled by the hygrometer. Specifically, when the humidity of the refrigerator compartment detected by the hygrometer is low, a control parameter corresponding to a higher humidification rate is determined, and the humidification device is controlled to release water vapor into the refrigerator compartment based on the control parameter. When the humidity of the refrigerator compartment detected by the hygrometer is high, a control parameter corresponding to a lower humidification rate is determined, and the humidification device is controlled to release water vapor into the refrigerator compartment based on the control parameter.

[0106] However, installing a hygrometer in the refrigerator compartment will increase the hardware cost of the refrigerator.

[0107] Based on this, the present application provides a refrigerator. Considering that the humidity in the cold storage room is related to the operating rate of the compressor, when a humidifying device is needed to humidify the cold storage room, the corresponding control parameters can be determined according to the operating rate of the compressor, and the humidifying device can be controlled to diffuse water vapor into the cold storage room by the control parameters, wherein the operating rate is proportional to the humidification rate corresponding to the control parameter. In this way, there is no need to set up additional hardware in the cold storage room, that is, there is no need to increase the hardware cost of the refrigerator. Moreover, by controlling the humidification of the cold storage room according to the operating rate of the compressor, the humidification rate of the water vapor diffused into the cold storage room is more in line with the cold storage room's demand for water vapor, and is more accurate.

[0108] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. For the same or similar concepts or processes, some embodiments may not be described in detail. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0109] First, the structure of the refrigerator provided in some embodiments of the present application is described.

[0110] In one possible implementation, Figure 1 is a schematic diagram of a refrigerator according to some embodiments, such as Figure 1 As shown, the refrigerator 10 includes a cabinet 101 .

[0111] The refrigerator 10 further includes a door 102 , which is connected to the housing 101 .

[0112] The refrigerator 10 further includes a storage chamber, which is disposed in the housing 101 .

[0113] In a possible implementation, the storage chamber includes a refrigeration chamber, and may also include a temperature-changing chamber and / or a freezer chamber, etc.

[0114] In a possible implementation, the refrigerator 10 further includes a controller and a compressor. Both the controller and the compressor are disposed in the box.

[0115] In the embodiment of the present application, the controller may be a microcontroller unit (MCU) or other types of controllers. The embodiment of the present application does not specifically limit the controller.

[0116] In a possible implementation, the refrigerator further includes a humidifying device, which is disposed on a door corresponding to the refrigerating chamber. The humidifying device is configured with an outlet for diffusing water vapor in the humidifying device into the refrigerating chamber.

[0117] Figure 2 A schematic diagram of the structure of a humidifying device according to some embodiments Figure 1 .

[0118] like Figure 2 As shown, the humidifying device includes a humidifying water box and a humidifying component.

[0119] Humidification water box, used to store water.

[0120] The humidification component is used to convert the water in the humidification water box into water vapor.

[0121] Figure 3 A schematic diagram of the structure of a humidifying device according to some embodiments Figure 2 .

[0122] Figure 4 A schematic diagram of the structure of a humidifying device according to some embodiments Figure 3 .

[0123] Figure 5A schematic diagram of the structure of a humidifying device according to some embodiments Figure 4 .

[0124] like Figure 5 As shown, the humidifying device is also provided with a water injection port, through which water can be injected into the humidifying water box.

[0125] In combination with the above content, the following describes the control method of the controller controlling the humidification device to humidify the refrigeration compartment during the operation of the refrigerator. For details, please refer to Figure 6 shown. Figure 6 A flow chart of a refrigerator control method according to some embodiments Figure 1 .

[0126] Figure 6 As shown, the refrigerator control method may include the following steps:

[0127] S601. When it is determined that a humidifying device is needed to humidify the refrigerating chamber, obtain the startup rate of the compressor.

[0128] Illustratively, to determine whether a humidifying device is needed to humidify the refrigerating chamber, it may be determined whether a preset condition is currently met. If the preset condition is met, it is determined that a humidifying device is needed to humidify the refrigerating chamber.

[0129] The preset condition may be a time interval, for example, whether the time interval between the current moment and the moment when the humidification was last stopped reaches a preset time interval, and when the preset time interval is reached, it is determined that the humidification device is required to humidify the refrigerating chamber.

[0130] The embodiment of the present application does not specifically limit the method for determining whether a humidifying device is needed to humidify the refrigerating chamber.

[0131] For example, obtaining the compressor's on-rate may be obtaining the compressor's on-rate during the previous operating cycle at the current moment, or obtaining the average on-rate within a preset time period before the current moment. The embodiment of the present application does not specifically limit the method for obtaining the compressor's on-rate.

[0132] S602: Determine control parameters according to the startup rate of the compressor.

[0133] In the present application, the humidification component may include one or more. For example, the humidification component may include at least one of a fan, a heating element, and an ultrasonic device. The embodiments of the present application do not specifically limit the humidification component.

[0134] When the type and quantity of humidifying components are different, the determined control parameters are different. For example, when the humidifying component includes a fan, the control parameter is the fan speed; when the humidifying component is a heating element, the control parameter is the power of the heating element.

[0135] The method for determining the control parameters according to the operating rate of the compressor can be referred to the following embodiment.

[0136] S603. According to the control parameters, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber, wherein the startup rate is proportional to the humidification rate corresponding to the control parameters.

[0137] It should be noted that when the compressor is running at a high rate, it indicates that the internal temperature of the refrigerator fluctuates greatly, and the refrigerator compartment requires higher humidity compensation to maintain the freshness of food. When the compressor is running at a low rate, it indicates that the internal temperature of the refrigerator is relatively stable, and the refrigerator compartment requires lower humidity compensation.

[0138] In the present application, the humidification component may include one or more. For example, the humidification component may include at least one of a fan, a heating element, and an ultrasonic device. The embodiments of the present application do not specifically limit the humidification component.

[0139] Depending on the type and number of humidifying components, the humidifying components are controlled differently based on the control parameters. For example, if the humidifying component includes a fan, the fan is controlled to operate at a determined fan speed. If the humidifying component includes a heating element, the heating element is controlled to operate based on a determined heating power.

[0140] The method for controlling the operation of the humidification component according to the control parameters can be referred to the following embodiments.

[0141] In this way, the control parameters for controlling the humidification component to humidify the refrigerator compartment are determined by the compressor's operating rate, so that the humidification component can diffuse water vapor into the refrigerator compartment at a humidification rate corresponding to the control parameters to adjust the humidity in the refrigerator compartment. This makes the humidity in the refrigerator compartment more consistent with the humidity requirements of the refrigerator compartment and has higher accuracy. Furthermore, there is no need to install a hygrometer in the refrigerator compartment.

[0142] In the present application, the humidification component may include at least one of a fan, a heating element, and an ultrasonic device.

[0143] The fan is used to generate airflow to convert the water in the humidification water box into water vapor, and diffuse the water vapor into the refrigerated compartment through the outlet.

[0144] The heating element is used to heat the water in the humidification water box so that the water in the humidification water box is converted into water vapor.

[0145] The ultrasonic device is used to use ultrasonic vibration to break up the water in the humidification water box into tiny water droplets to form water vapor.

[0146] Several possible implementations of determining the control parameters and controlling the operation of the humidification component according to the control parameters are described below.

[0147] In one possible implementation, the humidification component includes any one of a fan, a heating element, and an ultrasonic device.

[0148] When the humidifying component is a fan, the determined control parameter is the speed of the fan, the start-up rate of the compressor is proportional to the speed of the fan, and the speed of the fan is proportional to the humidification rate corresponding to the control parameter.

[0149] In this way, when the startup rate is large, the fan speed is determined to be large, and the humidification rate at this speed is large; when the startup rate is small, the fan speed is determined to be small, and the humidification rate at this speed is small.

[0150] When the humidifying component is a heating element, the determined control parameter is the power of the heating element. The startup rate of the compressor is proportional to the power of the heating element, and the power of the heating element is proportional to the humidification rate corresponding to the control parameter.

[0151] In this way, when the power-on rate is high, the power of the determined heating element is high, and the humidification rate under the power of the heating element is high. When the power-on rate is low, the power of the determined heating element is low, and the humidification rate under the power of the heating element is low.

[0152] When the humidifying component is an ultrasonic device, the determined control parameter is the power of the ultrasonic device. The startup rate of the compressor is proportional to the power of the ultrasonic device, and the power of the ultrasonic device is proportional to the humidification rate corresponding to the control parameter.

[0153] In this way, when the power-on rate is large, the power of the determined ultrasonic device is large, and the humidification rate under the power of the ultrasonic device is large. When the power-on rate is small, the power of the determined ultrasonic device is small, and the humidification rate under the power of the ultrasonic device is small.

[0154] In this way, when the humidification component includes any one of a fan, a heating element, or an ultrasonic device, different fan speeds, or different heating element powers, or different ultrasonic device powers are determined according to different compressor start-up rates to control the humidification device to diffuse water vapor into the refrigerated compartment at a corresponding humidification rate.

[0155] In another possible implementation, the humidification component includes any two of a fan, a heating element, and an ultrasonic device.

[0156] For example, the humidification component may include a fan and a heating element, or the humidification component may include a fan and an ultrasonic device, or the humidification component may include a heating element and an ultrasonic device. This embodiment of the present application does not specifically limit this.

[0157] In this possible implementation, the control parameter includes a first control parameter.

[0158] Figure 7A flow chart of a refrigerator control method according to some embodiments Figure 2 .

[0159] like Figure 7 As shown, the refrigerator control method may include:

[0160] S701. When it is determined that a humidifying device is needed to humidify the refrigerating chamber, obtain the startup rate of the compressor.

[0161] The method for obtaining the operating rate of the compressor can be found in the above embodiment and will not be repeated here.

[0162] S702: When the startup rate is less than a first preset startup rate, determine a first control parameter according to the startup rate of the compressor.

[0163] The embodiment of the present application does not limit the first preset power-on rate.

[0164] Exemplarily, the first control parameter is a control parameter of the corresponding humidifying component. For example, when the humidifying component is a fan, the first control parameter is the speed of the fan. When the humidifying component is a heating element, the first control parameter is the power of the heating element.

[0165] When the humidifying component is a fan, the start-up rate is proportional to the rotational speed of the fan, and the rotational speed of the fan is proportional to the humidification rate corresponding to the first control parameter.

[0166] When the humidifying component is a heating element, the on-rate is proportional to the power of the heating element, and the power of the heating element is proportional to the humidifying rate corresponding to the first control parameter.

[0167] When the humidifying component is an ultrasonic device, the on-rate is proportional to the power of the ultrasonic device, and the power of the ultrasonic device is proportional to the humidifying rate corresponding to the first control parameter.

[0168] S703: According to the first control parameter, control one of the two humidifying components to operate so that the water in the humidifying water box is converted into water vapor and diffused into the refrigerating chamber.

[0169] According to the determined first control parameter, the corresponding humidifying component is controlled to operate.

[0170] For example, when the first control parameter is the power of the heating element, the heating element is controlled to operate at the power of the first control parameter.

[0171] In this way, when the startup rate is low, the demand for water vapor in the refrigeration chamber is small. Therefore, one of the two humidification components can be controlled to operate, which can reduce the waste of unnecessary resources.

[0172] In this possible implementation, the control parameter includes a second control parameter.

[0173] Figure 8 A flow chart of a refrigerator control method according to some embodiments Figure 3 .

[0174] like Figure 8 As shown, the refrigerator control method may include:

[0175] S801. When it is determined that a humidifying device is needed to humidify the refrigerating chamber, obtain the startup rate of the compressor.

[0176] The method for obtaining the operating rate of the compressor can be found in the above embodiment and will not be repeated here.

[0177] S802: When the startup rate is greater than or equal to the first preset startup rate, determine a second control parameter according to the startup rate of the compressor.

[0178] The second control parameter includes the content corresponding to the two humidification components. For example, when the humidification component includes a fan and a heating element, the second control parameter includes the fan speed and the heating element power. When the humidification component includes a fan and an ultrasonic device, the second control parameter includes the fan speed and the ultrasonic device power.

[0179] S803. According to the second control parameter, control both humidification components to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber; the humidification rate corresponding to the second control parameter is greater than the humidification rate corresponding to the first control parameter.

[0180] The two humidifying components are controlled to operate according to the determined second control parameter.

[0181] For example, when the humidification component includes a fan and a heating element, the second control parameter includes the speed of the fan and the power of the heating element. According to the second control parameter, the fan is controlled to operate at the speed of the second control parameter, and the heating element is controlled to operate at the power of the second control parameter.

[0182] In this way, when the startup rate is high, the demand for water vapor in the refrigerating chamber is high. Therefore, the two humidifying components can be controlled to run simultaneously, so that the humidification rate is high and the time for humidifying the refrigerating chamber can be shortened.

[0183] In another possible implementation, the humidification component includes a fan, a heating element, and an ultrasonic device. The control parameter includes a third control parameter.

[0184] Figure 9 A flow chart of a refrigerator control method according to some embodiments Figure 4 .

[0185] like Figure 9 As shown, the refrigerator control method may include:

[0186] S901. When it is determined that a humidifying device is needed to humidify the refrigerating chamber, obtain the startup rate of the compressor.

[0187] The method for obtaining the operating rate of the compressor can be found in the above embodiment and will not be repeated here.

[0188] S902. Determine, based on the startup rate and the first corresponding relationship, the N humidification components that need to be run corresponding to the startup rate, and the third control parameters corresponding to the N humidification components; the first corresponding relationship is the startup rate, the target humidification component that needs to be run, and the control parameters corresponding to the target humidification component; N is one of 1, 2, and 3, and N is proportional to the startup rate.

[0189] In this application, different startup rates determine that different numbers of humidification components are in operation.

[0190] For example, when the on-rate is less than a first value, one humidifying component is determined to be operating, and the third control parameter is the parameter for controlling the operation of that component. When the on-rate is greater than or equal to the first value and less than a second value, two humidifying components are determined to be operating, and the third control parameter is the operating parameter corresponding to the two humidifying components. When the on-rate is greater than or equal to the second value, three humidifying components are determined to be operating simultaneously, and the third control parameter is the operating parameter corresponding to the three humidifying components.

[0191] S903. According to the third control parameter, control the target humidification component to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber; the humidification rate corresponding to the third control parameter is proportional to N.

[0192] When the third control parameter includes the operating parameters of one humidifying component, the humidifying component is controlled to operate. When the third control parameter includes the operating parameters of two humidifying components, the corresponding two humidifying components are controlled to operate. When the third control parameter includes the operating parameters of three humidifying components, the three humidifying components are controlled to operate simultaneously.

[0193] In this way, the number of humidifying components used to diffuse water vapor into the refrigerated compartment is determined based on the power-up rate. When the power-up rate is high, i.e., when the refrigerated compartment has a greater demand for water vapor, the humidification rate of water vapor diffusion into the refrigerated compartment is high. When the power-up rate is low, i.e., when the refrigerated compartment has a lower demand for water vapor, the humidification rate of water vapor diffusion into the refrigerated compartment is low. This ensures that the humidification rate of the humidifying device diffuses water vapor into the refrigerated compartment and the demand for water vapor in the refrigerated compartment matches, resulting in more accurate control of the humidifying device's water vapor diffusion into the refrigerated compartment.

[0194] In this application, in addition to determining the control parameters based on the power-on rate, the number of times the refrigerator door is opened and closed and the ambient temperature can also be considered. Figure 10 A flow chart of a refrigerator control method according to some embodiments Figure 5 .

[0195] like Figure 10 As shown, the refrigerator control method may include:

[0196] S1001. When it is determined that a humidifying device is needed to humidify the refrigerating chamber, obtain the ambient temperature and the number of times the door is opened within a preset operating time before the current moment.

[0197] Exemplarily, the refrigerator is also provided with a temperature detection device, such as a temperature sensor, etc., through which the ambient temperature of the refrigerator can be detected.

[0198] The preset running time can be 12 hours or 24 hours. The embodiment of the present application does not specifically limit the preset running time.

[0199] S1002. Determine control parameters according to the startup rate, ambient temperature, and number of times.

[0200] When the ambient temperature is high, the refrigerator will continuously remove moisture from the refrigerator compartment through the refrigeration system, making the air in the refrigerator compartment relatively dry. Therefore, when the ambient temperature is high, the refrigerator compartment has a greater demand for water vapor.

[0201] When the refrigerator door is opened, outside air is drawn in. If the outside humidity is low (such as in a dry winter), the humidity in the refrigerator compartment decreases. If the outside humidity is high (such as in a humid rainy season), the humidity in the refrigerator compartment temporarily rises, and the refrigerator controls the refrigeration system, which removes moisture from the refrigerator compartment. Therefore, the more times the refrigerator door is opened within the preset operating time, the greater the demand for moisture in the refrigerator compartment.

[0202] Therefore, the startup rate, ambient temperature and number of times are all proportional to the humidification rate corresponding to the control parameters.

[0203] Taking the preset operating time as 24 hours as an example, the corresponding relationship between the power-on rate, ambient temperature, number of times and humidification rate can be as described in the following Table 1.

[0204] Table 1

[0205]

[0206]

[0207] It should be noted that when the door has not been opened for 24 hours, it can be determined that the refrigerator is in energy-saving mode.

[0208] The present application embodiment is merely described by taking Table 2 as an example and does not constitute any limitation.

[0209] S1003. According to the control parameters, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber.

[0210] The method for controlling the operation of the humidification component according to the control parameters can be referred to the above embodiment and will not be repeated here.

[0211] In this way, while considering the startup rate, the number of times the door is opened during preset operation and the ambient temperature are also considered, so that the humidification rate corresponding to the determined control parameters is more in line with the refrigeration room's demand for water vapor, making the control of the humidification of the refrigeration room more accurate.

[0212] In conjunction with the above embodiments, the humidification component may include at least one of a fan, a heating element, and an ultrasonic device. The functions of the fan, the heating element, and the ultrasonic device can be referred to the above embodiments and will not be repeated here.

[0213] In the present application, the control parameter may include a fourth control parameter.

[0214] When considering the compressor's operating rate, refrigerator door opening and closing times, and ambient temperature, the corresponding control method can be as follows: Figure 11 As shown, Figure 11 A flow chart of a refrigerator control method according to some embodiments Figure 6 .

[0215] like Figure 11 As shown, the refrigerator control method may include:

[0216] S1101. When it is determined that a humidifying device is needed to humidify the refrigerating chamber, the startup rate of the compressor, the ambient temperature, and the number of times the door is opened within a preset operating time before the current moment are obtained.

[0217] The method for obtaining the compressor startup rate, ambient temperature and the number of times the door is opened can be found in the above embodiment and will not be repeated here.

[0218] S1102: Determine a corresponding fourth control parameter according to the power-on rate, ambient temperature, number of times, and the second corresponding relationship.

[0219] It should be noted that, if the humidification rate in Table 2 is replaced with the control parameter corresponding to the humidification rate, Table 1 can be regarded as the second corresponding relationship.

[0220] S1103. According to the fourth control parameter, control at least one humidifying component to operate so that the water in the humidifying water box is converted into water vapor and diffused into the refrigerated compartment; the power-on rate, ambient temperature, and number of times are proportional to the number of operating humidifying components.

[0221] Exemplarily, according to the fourth control parameter, the operation of at least one humidifying component is controlled, which can be described in the above embodiment and will not be repeated here.

[0222] In this way, the moisture demand of the refrigerated compartment can be determined based on the compressor's operating rate, ambient temperature, and the number of times the door is opened, thereby determining the operation of the humidifying components that need to be operated. When the refrigerated compartment's moisture demand is high, multiple humidifying components can be operated simultaneously to diffuse moisture into the refrigerated compartment at a high humidification rate. This ensures that the humidification rate corresponding to the determined control parameters matches the refrigerated compartment's moisture demand.

[0223] In the present application, when obtaining the number of times the door is opened within the preset operating time before the current moment, there may be a situation where the operating time of the refrigerator is less than the preset operating time.

[0224] Exemplarily, the control parameters further include a fifth control parameter, which is a preset default control parameter.

[0225] When the operating time of the refrigerator is less than the preset operating time, the controller can obtain the fifth control parameter; according to the fifth control parameter, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber.

[0226] In this way, when the operating time of the refrigerator is less than the preset operating time, the default control parameters can be used to control the humidifying device to diffuse water vapor into the refrigerating chamber.

[0227] In this application, when the humidification component is controlled to operate, the operating status of the compressor can be obtained; when the operating status of the compressor is stopped, the humidification component is controlled to operate so that the water in the humidification water box is converted into water vapor and diffused into the refrigeration chamber.

[0228] In this way, since the refrigeration system provides cooling to the cold storage room while taking away moisture from the cold storage room during the operation of the compressor, diffusing water vapor into the cold storage room when the compressor is stopped can reduce the situation where moisture is taken away by refrigeration, so that the moisture in the cold storage room can get the required amount as soon as possible.

[0229] The present application also provides a computer-readable storage medium, which may include: a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk, and other media that can store program codes. Specifically, the computer-readable storage medium stores computer execution instructions, which, when executed by a computer, are used to implement the technical solution shown in the above method embodiment.
