[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0053] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, when describing a pipeline, the "connected" and "connection" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0054] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] As described in the background technology, in areas with long-term humidity, serious air pollution, strong winds and sand, or other areas where it is inconvenient to dry clothes, dryers can meet people's needs for drying clothes, but at the same time, using dryers will increase the user's electricity burden.

[0056] In view of this, an embodiment of the present application provides a dryer, which includes: a shell, a drying drum and a controller; the drying drum is arranged in the shell and is used to load clothes to be dried; the controller is configured to: determine the predicted power consumption of the drying program during the running of the drying program; when the predicted power consumption is greater than the preset maximum power consumption of the drying program, perform energy-saving operations.

[0057] In this way, the predicted power consumption can be calculated in advance, and when the predicted power consumption is greater than the maximum power consumption, certain energy-saving operations can be taken to reduce the power consumption of executing the drying program so that the use of the dryer meets the maximum power consumption limit.

[0058] Figure 1 1 is a schematic diagram of the structure of the clothes dryer 100 provided in this application. Figure 1 As shown, the clothes dryer 100 includes one or more of the following: The clothes dryer includes: a housing 1, a clothes drying drum 2, a motor 3, a compressor 4, a drying fan 5, a drainage pump 6 and a controller 7 ( Figure 1 The controller 7 is connected to the motor 3, the compressor 4, the drying fan 5, and the drainage pump 6 respectively.

[0059] The clothes drying drum 2 is arranged in the housing 1 and is used to load clothes to be dried. There is an air duct between the housing 1 and the clothes drying drum 2. The clothes drying drum 2 has an air inlet and an air outlet. The two ends of the air duct are connected to the air inlet and the air outlet of the clothes drying drum 2 respectively.

[0060] In some embodiments, an evaporator and a condenser are provided in the air duct between the housing 1 and the clothes drying drum 2. The evaporator is used to condense the steam generated by the clothes dryer into condensed water, and the condenser is used to increase the air temperature so that the passing air becomes dry and hot air.

[0061] The motor 3 is used to provide driving power for the clothes dryer 100. Figure 1 As shown, when the clothes dryer is drying clothes, the motor 3 can drive the drying drum 2 to rotate via a belt.

[0062] The compressor 4 is used to drive the refrigerant circulation in the dryer 100 to further realize the air circulation in the dryer 100. Optionally, the air intake of the compressor 4 is connected to one end of the evaporator, the other end of the evaporator is connected to one end of the condenser through a pipeline, and the other end of the condenser is connected to the exhaust port of the compressor.

[0063] The drying fan 5 is used to increase the air pressure in the air duct and discharge the high-pressure air. It is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It can also be a ventilator, a blower, and a wind turbine. The drying fan 5 can be set at the condenser so that the hot air generated by the heat generated by the condenser is blown into the drying drum 2, and the air can circulate in a directional manner in the air duct.

[0064] Among them, when the dryer 100 is working, the drying fan 5 drives the air to circulate in a directional manner in the air duct. After the compressor 4 is started, the air is heated by the condenser and then blown into the drying drum 2. The hot air comes into contact with the wet clothes in the drying drum 2 and becomes hot and humid air. The hot and humid air flows into the evaporator through the air duct. The hot and humid air is cooled by heat exchange in the evaporator, and condensed water is generated. The air in the air duct is repeatedly heated and condensed until the dryer 100 completes this drying task.

[0065] Drain pump 6, such as Figure 1 As shown, the condensed water generated by the humid hot air lowering its temperature through heat exchange in the evaporator will flow into the water tank, and the drain pump 6 is used to discharge the condensed water in the water tank.

[0066] The controller 7 refers to a device or apparatus that can generate an operation control signal according to the instruction operation code and the timing signal to instruct the clothes dryer 100 to execute the clothes drying program. Exemplarily, the controller 6 can be a central processing unit (CPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof.

[0067] The controller 7 may also be other devices with processing functions, such as circuits, devices or software modules, and the present application embodiment does not impose any limitation on this. The controller 7 may control the clothes dryer 100 to run or end a clothes drying program.

[0068] In some embodiments of the present application, the controller 7 can be used to determine the predicted power consumption of the drying program during the operation of the drying program; when the predicted power consumption is greater than the preset maximum power consumption of the drying program, perform energy-saving operations, thereby completing the drying task with less power consumption.

[0069] In some embodiments, the clothes dryer 100 further includes a heater 8, which is connected to the controller 7 and is used to assist in heating the circulating air to increase the drying speed. The heater 8 can be a common electric heating device that uses electrical energy to achieve a heating effect, including but not limited to a steam heater and a hot air heater.

[0070] In some embodiments, the clothes dryer 100 may further include a humidity sensor 9 connected to the controller 7. The humidity sensor 9 is disposed in the clothes dryer 2, and is used to detect the humidity value in the clothes dryer 2 in real time, and send the detected humidity value in the clothes dryer 2 to the controller 7.

[0071] In some embodiments, the clothes dryer 100 may further include a timing device 10 ( Figure 1 ), which is connected to the controller 7. When the clothes dryer runs a drying program, the timing device 10 can be used to record the running time of the drying program and send the acquired running time of the drying program to the controller 7.

[0072] In some embodiments, the clothes dryer 100 may further include a display device 11 ( Figure 1The display device 11 is used to display the actual power consumption of the clothes dryer when running the clothes drying program.

[0073] Those skilled in the art will understand that Figure 1 The clothes dryer 100 shown in the figure may further include, for example, a temperature sensor or other possible components, which will not be described in detail herein.

[0074] For example, the clothes dryer 100 provided in the embodiment of the present application can be applied to Figure 2 In the smart home system shown in the figure. Figure 2 As shown, the smart home system may include a clothes dryer 100, a server, and an electronic device. The server may establish connections with the clothes dryer 100 and the electronic device, respectively, to achieve mutual communication. It should be understood that the connection method may be a wireless connection, such as a Bluetooth connection, a Wi-Fi connection, etc.; or the connection method may also be a wired connection, such as an optical fiber connection, etc., without limitation.

[0075] Exemplarily, the dryer 100 may further include a communication module, and the communication module of the dryer 100 is used to establish a communication connection with the electronic device through the server.

[0076] In some embodiments, when a user needs to use a clothes dryer to dry clothes, the user can send a control instruction to the server through the electronic device, and after receiving the control instruction, the server sends the control instruction to the clothes dryer 100. Accordingly, the clothes dryer 100 can receive the control instruction and perform corresponding operations, such as operating according to the control instruction to dry clothes. Optionally, the clothes dryer 100 and the electronic device 102 can also communicate by wireless connection.

[0077] Exemplarily, the user can operate on the first application installed on the electronic device, and remotely control the dryer 100 by transmitting control instructions through a wireless communication network (for example, a 3G network, a 4G network, etc.) or by wireless means (for example, Wireless Fidelity (WiFi)). The first application is a control program for the dryer 100. The embodiment of the present application does not limit the specific communication method. Optionally, the user can also operate directly on the dryer 100 to control the smart home device 101.

[0078] The electronic device in the embodiment of the present application can be any form of mobile terminal. For example, a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR)\virtual reality (VR) device, etc. The embodiment of the present application does not impose any special restrictions on the specific form of the electronic device. In addition, in the embodiment of the present application, the user can send a control instruction to the dryer 100 through the electronic device to control the dryer 100.

[0079] The server in the embodiment of the present application may be a device with data processing capability and data storage capability. Exemplarily, it may be a single server, or a server cluster consisting of multiple servers, or a cloud computing service center, which is not limited thereto. Optionally, the server in the embodiment of the present application may be a background server of an application for controlling home appliances.

[0080] Optional, Figure 2 The smart home system shown may also include other home appliances in addition to the clothes dryer 100. For example, televisions, smart speakers, water heaters, cameras, air conditioners, refrigerators, smart curtains, table lamps, chandeliers, rice cookers, security equipment (such as smart electronic locks), and other devices that can access the home wireless local area network. In addition, the above-mentioned home appliances are also equipped with wireless fidelity (WIFI) modules to establish connections with servers or electronic devices for mutual communication.

[0081] like Figure 3 As shown, an embodiment of the present application provides a control method for a clothes dryer, the method comprising the following steps:

[0082] S101 . During the running of a clothes drying program, a controller determines a predicted power consumption of the clothes drying program.

[0083] When a user uses a clothes dryer to dry clothes, the user can input a control instruction through an electronic device or directly on the clothes dryer according to his or her own needs. Accordingly, after receiving the control instruction input by the user, the clothes dryer can run a drying program corresponding to the operation mode in the control instruction according to the control instruction.

[0084] The drying program may include target duration, target humidity, target electrical components corresponding to the drying program, and control parameters of each target electrical component. During the drying program, the dryer controls the target electrical components to operate according to the control parameters of each target electrical component corresponding to the drying program.

[0085] In addition, the target electrical components include: one or more of a compressor, a motor, a drying fan, a drainage pump or a heater. The predicted power consumption is the total power that the clothes dryer may consume to complete the drying program.

[0086] Optionally, during the operation of the drying program, the controller may periodically determine the predicted power consumption of the drying program to facilitate timely energy saving management. It should be understood that during the operation of the drying program, the predicted power consumption determined by the controller at different times may be different.

[0087] Further, when the user turns on the energy-saving function of the clothes dryer, or the clothes dryer turns on the energy-saving function by default, after the controller determines the predicted power consumption of the clothes drying program, the controller can compare the calculated predicted power consumption with the preset maximum power consumption of the clothes drying program to determine whether it is necessary to perform the following step S102. The preset maximum power consumption can be a power consumption value preset in the clothes dryer or a power consumption value set by the user according to his own energy-saving needs.

[0088] In some embodiments, if the user does not select the energy-saving function of the dryer when starting the dryer, it means that the user currently has no energy-saving demand, or the user pays more attention to the drying effect than energy saving. At this time, the dryer operates normally according to the operating parameters corresponding to the drying program (that is, there is no need to execute Figure 3 The technical solution provided by the illustrated embodiment can achieve a better clothes drying effect.

[0089] S102: When the predicted power consumption is greater than the preset maximum power consumption of the clothes drying program, the controller performs an energy-saving operation.

[0090] It should be noted that if the predicted power consumption calculated by the controller is greater than the preset maximum power consumption of the drying program, it means that several clothes dryers continue to operate according to the current operating parameters, and the power consumption required by the dryer to complete the current drying task may be greater than the preset maximum power consumption, thereby failing to meet the user's energy saving needs. Therefore, when the predicted power consumption is greater than the preset maximum power consumption of the drying program, the controller executes step S102 to perform corresponding energy-saving operations to reduce the power consumption of the corresponding electrical components, thereby reducing the power consumption of the dryer.

[0091] It should be understood that if the predicted power consumption calculated by the controller is less than or equal to the preset maximum power consumption of the drying program, it means that the clothes machines continue to operate according to the current operating parameters, and the power consumption of completing this drying task can meet the user's energy saving needs. Therefore, the controller may not perform energy-saving operations, but run the drying program normally.

[0092] In some embodiments, when the predicted power consumption is greater than the preset maximum power consumption of the drying program, the controller may perform one or more of the following energy-saving operations:

[0093] Operation 1. The controller lowers the target exhaust temperature of the compressor.

[0094] It should be understood that the higher the target exhaust temperature of the compressor, the greater the power consumption of the compressor. Therefore, by lowering the target exhaust temperature of the compressor, the power consumption of the compressor can be reduced, thereby achieving the purpose of reducing the power consumption of the dryer.

[0095] Operation 2: The controller reduces the motor's run-stop ratio.

[0096] The motor's rotation-stop ratio is used to reflect the duration of the motor's rotation and the duration of the motor's stop rotation within a period of time. Therefore, reducing the motor's rotation-stop ratio means reducing the duration of the motor's rotation and increasing the duration of the motor's stop rotation. For example, the original motor rotates for 30 seconds and stops for 15 seconds; after reducing the motor's rotation-stop ratio, the motor rotates for 20 seconds and stops for 20 seconds.

[0097] It should be understood that the power consumption of the motor is related to the accumulated running time of the motor and the power of the motor. The longer the accumulated running time of the motor is, the greater its power consumption is. Therefore, by reducing the motor's start-stop ratio, the accumulated running time of the motor can be reduced. If the motor maintains the current power operation, the power consumption of the motor will decrease accordingly, and thus the power consumption of the clothes dryer will also decrease accordingly.

[0098] Operation 3: The controller reduces the speed of the drying fan.

[0099] It should be understood that the power consumption of the drying fan is related to the cumulative running time of the drying fan and the power of the drying fan. The greater the power of the drying fan, the greater its power consumption. It should be noted that the speed of the drying fan is positively correlated with the power of the drying fan. The greater the speed of the drying fan, the greater its power. Therefore, when the controller reduces the speed of the drying fan, the power of the drying fan will also decrease. If the cumulative running time of the drying fan remains unchanged, the power consumption of the drying fan will decrease accordingly, and thus the power consumption of the clothes dryer will also decrease accordingly.

[0100] Operation 4. The controller turns off the heater.

[0101] It should be understood that in the embodiment of the present application, the heater of the clothes dryer is used to assist in heating the circulating air. In the absence of the heater to assist in heating the circulating air, the clothes dryer can still complete the clothes drying process. In the case where the predicted power consumption calculated by the controller is greater than the preset maximum power consumption of the drying program, the controller can directly turn off the heater to meet the user's energy saving needs.

[0102] Operation 5: The controller increases the target humidity value of the drying program.

[0103] When the dryer is running a drying program, if the goal of the drying program is to dry the clothes to a target humidity value, the controller may also increase the target humidity value of the drying program when the predicted power consumption is greater than the preset maximum power consumption of the drying program.

[0104] It should be understood that the greater the difference between the initial humidity value of the clothes and the target humidity value, the longer the clothes drying time of the dryer is. Therefore, the controller increases the target humidity value, which can reduce the working time of the dryer, thereby meeting the user's energy saving needs.

[0105] In some embodiments, when the predicted power consumption is greater than the preset maximum power consumption of the drying program, the controller may take one or more energy-saving operations corresponding to each target power-consuming component related to the drying program according to each target power-consuming component related to the drying program.

[0106] Exemplarily, some clothes dryers are not equipped with heaters, and the target electrical components related to the current drying program of the dryer include a compressor, a motor, a drying fan and a drain pump. When the predicted power consumption is greater than the preset maximum power consumption of the drying program, the controller of the dryer can perform one or more of operation one, operation two or operation three in the above-mentioned energy-saving operations.

[0107] For example, the target electrical components related to the current drying program of several clothes dryers include a compressor, a motor, a drying fan, a drainage pump and a heater, and if the goal of the drying program is that the humidity in the drying drum reaches the target humidity, then when the predicted power consumption is greater than the preset maximum power consumption of the drying program, the controller of the clothes dryer can perform one or more of the above energy-saving operations: operation 1, operation 2, operation 3, operation 4 or operation 5.

[0108] The technical solution provided by the above-mentioned embodiment brings at least the following beneficial effects: the controller of the dryer can calculate in advance the predicted power consumption required to complete the drying program during the running of the drying program; when the calculated predicted power consumption is greater than the maximum power consumption, the controller of the dryer performs energy-saving operations, which can reduce the power consumption of executing the drying program, so that the use of the dryer can meet the maximum power consumption limit as much as possible (that is, the power consumption of finally completing the drying program is only as much as possible less than the maximum power consumption), thereby achieving the effect of energy saving and emission reduction.

[0109] In some embodiments, based on Figure 3 The embodiment shown, as Figure 4 As shown, the above step S101 can be specifically implemented as follows:

[0110] S1011. During the running of the clothes drying program, the controller obtains the actual power consumption of the clothes drying program from the start time to the current time.

[0111] According to the description in step S101, the clothes drying program may include its corresponding target electrical components. During the running of the clothes drying program, each target electrical component in the clothes dryer related to the clothes drying program may be in operation.

[0112] In addition, the target electrical components related to the clothes drying program may include: one or more of: a compressor, a motor, a drying fan, a drainage pump or a heater.

[0113] In some embodiments, the controller may calculate the power consumption of each target electrical component related to the drying program at the current moment, and use the sum of the power consumption of all target electrical components as the actual power consumption of the drying program from the start moment to the current moment.

[0114] Optionally, the controller may obtain the power and accumulated operating time of each target electrical component related to the clothes drying program at the current moment, and determine the power consumption of each target electrical component according to the power and accumulated operating time of each target electrical component.

[0115] Exemplarily, the calculation process of the power consumption of each of the above-mentioned electrical components is shown below:

[0116] (1) Compressor

[0117] Exemplarily, the actual power consumption of the compressor may satisfy the following relationship:

[0118] Q 1 =t 1 ×P 1

[0119] Among them, Q 1 Indicates the actual power consumption of the compressor; t1 Indicates the cumulative running time of the compressor; P 1 Indicates the power of the compressor. For example, P 1 It can be determined based on the model of the compressor installed in the dryer.

[0120] For example, if the controller obtains that the power of the compressor is 0.1 kilowatt, and the cumulative running time of the compressor is 30 minutes, that is, t 1 = 30 minutes = 0.5 hours, P 1 =0.1 kW. Then the actual power consumption of the compressor is Q 1 =0.1×0.5=0.05 kWh.

[0121] (2) Motor

[0122] Exemplarily, the actual power consumption of the motor may satisfy the following relationship:

[0123] Q 2 =t 2 ×P 2

[0124] Among them, Q 2 Indicates the actual power consumption of the motor; t 2 Indicates the accumulated running time of the motor; P 2 Indicates the power of the motor. For example, P 2 This can be determined based on the motor model set in the dryer.

[0125] In addition, since the motor is periodically operated, the controller can determine t according to the actual operation time T of the dryer and the motor's start-stop ratio X. 2 .

[0126] The above-mentioned motor rotation-stop ratio refers to the ratio of the rotation duration of the motor within one operation cycle of the motor to the total duration of the operation cycle.

[0127] Exemplarily, the accumulated running time of the motor may satisfy the following relationship:

[0128] t 2 =T×X

[0129] For example, if during the execution of the drying program, the actual running time of the dryer is 50 minutes, and the motor stop ratio X is 60%, then the accumulated running time of the motor is 2 t 2 =50 minutes × 60% = 30 minutes.

[0130] (3) Drying fan

[0131] Exemplarily, the actual power consumption of the drying fan may satisfy the following relationship:

[0132] Q 3 =t 3 ×P 3

[0133] Among them, Q 3 Indicates the actual power consumption of the drying fan; t 3 Indicates the cumulative running time of the drying fan; P 3 Indicates the power of the drying fan. For example, during the execution of the drying program, t 3 It can be the actual running time T of the clothes dryer. 3 It can be the actual power of the drying fan that executes the drying program.

[0134] (4) Drainage pump

[0135] Exemplarily, the actual power consumption of the drainage pump may satisfy the following relationship:

[0136] Q 4 =t 4 ×P 4

[0137] Among them, Q 4 Indicates the actual power consumption of the drainage pump; t 4 Indicates the cumulative running time of the drainage pump; P 4 Indicates the power of the drain pump. For example, during the execution of the drying program, t 4 It can be the actual running time T of the clothes dryer. 4 The model determination of the drain pump set in the dryer can be performed.

[0138] (5) Heater

[0139] Exemplarily, the actual power consumption of the heater may satisfy the following relationship:

[0140] Q 5 =t 5 ×P 5

[0141] Among them, Q 5 Indicates the actual power consumption of the heater; t 5 Indicates the cumulative running time of the heater; P 5 Indicates the power of the heater. For example, during the execution of the drying program, t 5 It can be the actual running time T of the clothes dryer. 5 The model determination of the heater set in the dryer can be performed.

[0142] Furthermore, when the clothes dryer is running a drying program, the controller may use the sum of the power consumption of each target electrical component related to the drying program as the actual power consumption of the drying program from the start time to the current time.

[0143] For example, if the target electrical components of the clothes drying program include: a compressor, a motor, a drying fan, a drainage pump, and a heater, the power consumption of the clothes dryer satisfies the following relationship:

[0144] Q=Q 1 +Q 2 +Q 3 +Q 4 +Q 5

[0145] Among them, Q is the power consumption of the dryer, Q 1 Indicates the actual power consumption of the compressor; Q 2 Indicates the actual power consumption of the motor; Q 3 Indicates the actual power consumption of the drying fan; Q 4 Indicates the actual power consumption of the drainage pump; Q 5 Indicates the actual power consumption of the heater.

[0146] In some embodiments, after calculating the current actual power consumption, the controller may issue a power consumption reminder so that the user can understand the current actual power consumption of the dryer in real time.

[0147] In one example, some clothes machines include voice reminder devices, and after calculating the current actual power consumption, the controller can control the dryer to broadcast "currently 1 kWh of power has been used" or other similar reminder information. Alternatively, some clothes machines include display devices, and after calculating the current actual power consumption, the controller can control the display device to display the calculated current actual power consumption of running the drying program, so that the user can view it.

[0148] In another example, several clothes machines are in Figure 2 In the smart home system shown, after calculating the current actual power consumption, the clothes dryer can send a notification instruction to the electronic device through the server, so that the electronic device can display the current actual power consumption of running the clothes drying program. In this way, the user does not need to check the actual power consumption next to the clothes dryer, and can remotely and in real time understand the actual power consumption of the clothes dryer through the electronic device.

[0149] In some embodiments, when the current actual power consumption is greater than the preset maximum power consumption, the controller can control the dryer to send a reminder message that the power consumption exceeds the limit.

[0150] For example, when the current actual power consumption is greater than the preset maximum power consumption, the controller of the dryer can control the dryer to issue a reminder message of excessive power consumption by broadcasting a prompt voice, playing a prompt sound, or displaying a reminder text on a display device.

[0151] Alternatively, the controller of the clothes dryer may control the clothes dryer to send a reminder message through a server or directly to the electronic device, so that the electronic device may send a reminder message indicating that the power consumption exceeds the standard.

[0152] S1012: The controller determines the predicted power consumption of the drying program according to the actual power consumption and the target of the drying program.

[0153] In some embodiments, the goal of the drying program can be that the dryer continues to dry clothes within a target duration. The drying program based on this goal can be called a "timed drying" drying program. When the dryer executes the "timed drying" drying program, it will continue to work until the working time reaches the preset target time.

[0154] Optionally, the target duration may be a preset operating duration of the dryer (eg, a standard mode of the dryer may be a fixed operating duration), or an operating duration set by a user (eg, a timing mode of the dryer).

[0155] In other embodiments, the goal of the drying program may be to dry the clothes to a target humidity value. The drying program based on this goal may be called a "stop when clothes are dry" drying program. When the dryer executes the "stop when clothes are dry" drying program, it will continue to work until the current humidity of the drying drum (or the clothes in the drying drum) reaches the target humidity.

[0156] Optionally, the target humidity may also be a preset humidity value of the dryer (eg, a stop-when-dry mode of the dryer) or a target humidity value set by a user.

[0157] This embodiment provides a method for calculating predicted power consumption. The controller of the clothes dryer can first calculate the actual power consumption of each target power-consuming component corresponding to the clothes drying program, and use the sum of the actual power consumption of each target power-consuming component as the actual power consumption of running the clothes drying program. In this way, the actual power consumption of running the clothes drying program can be calculated more accurately. Therefore, the controller can further determine the predicted power consumption of the clothes drying program based on the calculated actual power consumption.

[0158] As a possible implementation method, for the "timed drying" drying program, based on Figure 4 The embodiment shown, as Figure 5 As shown, the above step S1012 can be specifically implemented as follows:

[0159] S10121. If the goal of the clothes drying program is to dry the clothes continuously within a target time, the controller obtains the running time of the clothes drying program from the start time to the current time.

[0160] The controller may obtain the running time of the drying program from the start time to the current time through the timing device of the dryer.

[0161] In addition, the specific steps for determining the actual power consumption of the drying program from the start time to the current time can refer to the relevant description in the above step S1011, which will not be repeated here.

[0162] S10122. The controller determines the remaining running time according to the target time and the running time.

[0163] The controller may obtain the target duration of the drying program from the operating parameters corresponding to the drying program.

[0164] In addition, the remaining running time is the time from the current moment to the end moment of the running of the drying program by the clothes dryer.

[0165] Exemplarily, the remaining running time satisfies the following relationship:

[0166] Remaining running time = target time - running time

[0167] S10123. The controller determines the predicted power consumption of the drying program according to the running time, the actual power consumption and the remaining running time.

[0168] It should be noted that the predicted power consumption is the total power that the dryer may consume to complete the drying program, that is, the power consumption of the dryer controlling the target electrical components to operate with the control parameters of each target electrical component corresponding to the drying program from the start time to the end time of the drying program. The actual power consumption is the power consumption of the dryer controlling the target electrical components to operate with the control parameters of each target electrical component corresponding to the drying program from the start time to the current time.

[0169] Assuming that during the remaining running time of the drying program, the dryer still controls the target electrical components to operate with the control parameters of each target electrical component corresponding to the drying program. The controller can infer the remaining power consumption required to complete the drying program based on the actual power consumption, the running time and the remaining running time of the drying program. The remaining power consumption is the power consumption required by the dryer from the current time to the end time of the drying program.

[0170] Furthermore, the sum of the actual power consumption and the estimated remaining power consumption is the predicted power consumption for completing the clothes drying program.

[0171] Exemplarily, the above predicted power consumption may satisfy the following relationship:

[0172]

[0173] The above embodiment provides a method for calculating predicted power consumption based on actual power consumption. When the goal of the drying program is to continuously dry clothes within a target time, the controller of the dryer can determine the predicted power consumption of the drying program based on the running time, actual power consumption and remaining running time.

[0174] As another possible implementation, for the "stop when clothes are dry" drying program, based on Figure 4 The embodiment shown, as Figure 6 As shown, the above step S1012 can be specifically implemented as follows:

[0175] S10124: The goal of the drying program is to dry the clothes to a target humidity value, so the controller obtains a current humidity value detected by the humidity sensor at the current moment and an initial humidity value detected at the start of the drying program.

[0176] The controller may obtain the target humidity value of the drying program from the operating parameters corresponding to the drying program.

[0177] S10125. The controller determines a first humidity difference based on the current humidity value and the initial humidity value.

[0178] The first humidity difference is the difference between the initial humidity value and the current humidity value.

[0179] S10126. The controller determines a second humidity difference value based on the current humidity value and the target humidity value.

[0180] The second humidity difference is the difference between the current humidity value and the target humidity value.

[0181] S10127. The controller determines the predicted power consumption of the drying program according to the actual power consumption, the first humidity difference, and the second humidity difference.

[0182] It should be noted that the predicted power consumption is the total power that the dryer may consume to complete the drying program, that is, the power consumption required by the dryer when the humidity value detected by the humidity sensor changes from the initial humidity value to the target humidity value.

[0183] Assume that from the start time to the end time of the drying program, the clothes dryer always controls the target electrical components to operate with the control parameters of each target electrical component corresponding to the drying program. The actual power consumption is the power consumption required by the clothes dryer during the process in which the humidity value detected by the humidity sensor changes from the initial humidity value to the current humidity value. Therefore, the controller can infer the remaining power consumption required to complete the drying program based on the actual power consumption, the first humidity difference and the second humidity difference. The remaining power consumption is the power consumption required by the clothes dryer during the process in which the humidity value detected by the humidity sensor changes from the current humidity value to the target humidity value.

[0184] Furthermore, the sum of the actual power consumption and the estimated remaining power consumption is the predicted power consumption for completing the clothes drying program.

[0185] Exemplarily, the predicted power consumption of the above-mentioned clothes drying program satisfies the following relationship:

[0186]

[0187] In the embodiment of the present application, the predicted power consumption can be determined more accurately in two situations according to the goal of the drying program.

[0188] The above embodiment provides another method for calculating predicted power consumption based on actual power consumption. When the goal of the drying program is to dry the clothes to a target humidity value, the controller of the dryer can calculate the first humidity difference and the second humidity difference, and further determine the predicted power consumption of the drying program based on the actual power consumption, the first humidity difference and the second humidity difference.
