In addition, above-mentioned household electrical appliances still possess wireless fidelity (WIFI) module to establish being connected with server or electronic equipment, so that intercommunication.

As shown in fig. 3, an embodiment of the present application provides a control method of a dryer, the method including the steps of:

s101, in the process of running the clothes drying program, the controller determines the predicted power consumption of the clothes drying program.

When a user dries clothes by using the clothes dryer, the user can input a control instruction according to the requirement of the user through electronic equipment or directly on the clothes dryer. Correspondingly, after receiving the control instruction input by the user, the clothes dryer can operate the clothes drying program corresponding to the operation mode in the control instruction according to the control instruction.

The clothes drying program may include working parameters such as a target duration, a target humidity, a target electric element corresponding to the clothes drying program, and control parameters of each target electric element. In the process of running the clothes drying program, the clothes dryer controls the target electric elements to run according to the control parameters of the target electric elements corresponding to the clothes drying program.

Further, the target electrical component includes: one or more of a compressor, a motor, a drying fan, a drain pump, or a heater. The predicted power consumption is a total amount of power that may be consumed by the dryer to perform the drying process.

Optionally, in the process of operating the clothes drying program, the controller may periodically determine the predicted power consumption of the clothes drying program, so as to perform energy-saving management in time. It should be appreciated that the predicted power consumption determined by the controller at different times during the operation of the drying program may be different.

Further, in case that the user turns on the energy saving function of the dryer or the dryer turns on the energy saving function by default, after the controller determines the predicted power consumption amount of the drying program, the controller may compare the calculated predicted power consumption amount with the preset maximum power consumption amount of the drying program to determine whether the following step S102 needs to be performed. The preset maximum power consumption can be a preset power consumption value in the clothes dryer or a power consumption value set by a user according to the self energy-saving requirement.

In some embodiments, if the user does not select the energy saving function of the dryer when starting the dryer, it indicates that the user does not currently have an energy saving requirement, or the user pays more attention to the drying effect than energy saving, and at this time, the dryer normally operates according to the operation parameters corresponding to the drying program (i.e., the technical scheme provided by the embodiment shown in fig. 3 does not need to be executed), so that a better drying effect can be obtained.

And S102, when the predicted power consumption is larger than the preset maximum power consumption of the clothes drying program, the controller executes energy-saving operation.

It should be noted that, if the predicted power consumption calculated by the controller is greater than the preset maximum power consumption of the clothes drying program, it indicates that the plurality of clothes dryers continue to operate according to the current operating parameters, and the power consumption required by the clothes dryer to complete the current clothes drying task may be greater than the preset maximum power consumption, so as to not meet the energy saving requirement of the user. Therefore, when the predicted power consumption is greater than the preset maximum power consumption of the clothes drying program, the controller performs step S102 to perform a corresponding energy saving operation to reduce the power consumption of the corresponding power consumption element, thereby reducing the power consumption of the clothes dryer.

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 clothes drying program, it indicates that a plurality of clothes dryers continue to operate according to the current operating parameters, and the power consumption for completing the current clothes drying task can meet the energy-saving requirement of the user. Therefore, the controller may not perform the energy saving operation but normally operate the drying process.

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

and operating the first step, and reducing the target exhaust temperature of the compressor by the controller.

It should be appreciated that the higher the target discharge temperature of the compressor, the greater the power consumption of the compressor. Therefore, the power consumption of the compressor can be reduced by reducing the target exhaust temperature of the compressor, and the purpose of reducing the power consumption of the clothes dryer is achieved.

And secondly, reducing the rotation-stop ratio of the motor by the controller.

The rotation-stop ratio of the motor is used for reflecting the rotation time length of the motor in a period of time and the rotation stop time length of the motor. Therefore, the rotation-stop ratio of the motor is reduced, the rotation time of the motor is shortened, and the rotation stop time of the motor is prolonged. For example, the original motor rotates for 30s, and stops rotating for 15 s; after lowering the rotation stop ratio of the motor, the motor is rotated for 20s, and the rotation is stopped for 20 s.

It should be understood that the power consumption of the motor is related to the accumulated operating time period of the motor and the power of the motor, and the longer the accumulated operating time period of the motor, the greater the power consumption thereof. Therefore, by reducing the rotation-stop ratio of the motor, the cumulative operating time period of the motor can be reduced. If the motor keeps the current power running, the power consumption of the motor is reduced, and the power consumption of the clothes dryer is reduced accordingly.

And thirdly, reducing the rotating speed of the drying fan by the controller.

It should be understood that the power consumption of the drying fan is related to the accumulated operation time of the drying fan and the power of the drying fan, and the power of the drying fan is larger. It should be noted that the rotation speed of the drying fan is positively correlated with the power of the drying fan, and the larger the rotation speed of the drying fan is, the larger the power thereof is. Therefore, the controller reduces the rotating speed of the drying fan, and the power of the drying fan is reduced accordingly. If the accumulated operation time of the drying fan is not changed, the power consumption of the drying fan is reduced, and the power consumption of the clothes dryer is reduced accordingly.

And fourthly, the controller turns off the heater.

It should be understood that in the embodiment of the present application, the heater of the dryer is used to assist in heating the circulated air, and the dryer can still complete the laundry drying process without the heater to assist in heating the circulated air. And under the condition that the predicted power consumption calculated by the controller is larger than the preset maximum power consumption of the clothes drying program, the controller can directly turn off the heater so as to meet the energy-saving requirement of a user.

And fifthly, the controller increases the target humidity value of the clothes drying program.

In the course of the clothes drying program running in the clothes dryer, if the target of the clothes drying program is to dry the clothes to the target humidity value, the controller may also increase the target humidity value of the clothes drying program when the predicted power consumption is greater than the preset maximum power consumption of the clothes drying program.

It should be understood that the greater the difference between the initial humidity value of the laundry and the target humidity value, the longer the drying time of the laundry by the dryer. Therefore, the controller increases the target humidity value, and can reduce the operating time of the dryer, thereby satisfying the energy saving requirement of the user.

In some embodiments, when the predicted power consumption amount is greater than the preset maximum power consumption amount of the clothes drying program, the controller may take one or more energy saving operations corresponding to each target power consumption element associated with the clothes drying program according to each target power consumption element associated with the clothes drying program.

For example, if heaters are not installed in several dryers and target electric components related to the current drying program of the dryer include a compressor, a motor, a drying fan, and a drain pump, the controller of the dryer may perform one or more of the first, second, or third operations of the energy saving operations when the predicted power consumption is greater than the preset maximum power consumption of the drying program.

For example, the current drying program of several clothes machines includes a compressor, a motor, a drying fan, a drain pump, and a heater, and the drying program targets the humidity in the drying drum to reach the target humidity. The controller of the dryer may perform one or more of the above-described energy saving operation one, operation two, operation three, operation four, or operation five when the predicted power consumption amount is greater than the preset maximum power consumption amount of the drying program.

The technical scheme provided by the embodiment at least has the following beneficial effects: the controller of the clothes dryer can calculate the predicted power consumption required for completing the clothes drying program in advance in the process of operating the clothes drying program; when the calculated predicted power consumption is larger than the maximum power consumption, the controller of the clothes dryer executes energy-saving operation, so that the power consumption for executing the clothes drying program can be reduced, the clothes dryer can be used as far as possible to meet the maximum power consumption limit (namely the power consumption for finally executing the clothes drying program is only smaller than the maximum power consumption as far as possible), and the effects of energy conservation and emission reduction are achieved.

In some embodiments, based on the embodiment shown in fig. 3, as shown in fig. 4, the step S101 may be specifically implemented as:

and S1011, in the process of running the clothes drying program, the controller acquires the actual power consumption of the clothes drying program from the starting time to the current time.

As can be seen from the above description in step S101, the clothes drying program may include its corresponding target power utilization element. During the operation of the drying program, various target power consuming elements in the dryer related to the drying program may be in an operating state.

In addition, the target power consumption components related to the clothes drying program may include: one or more of a compressor, a motor, a drying fan, a drain pump, or a heater.

In some embodiments, the controller may calculate the power consumption of each target power consumption element related to the clothes drying program at the current time, and use the sum of the power consumption of all the target power consumption elements as the actual power consumption of the clothes drying program from the starting time to the current time.

Optionally, the controller may obtain power and accumulated operating time of each target electric element related to the clothes drying program at the current time, and determine the power consumption of each target electric element according to the power and accumulated operating time of each target electric element.

For example, the following shows a calculation process of the power consumption amount of each of the above-described power consumption elements:

(1) compressor with a compressor housing having a plurality of compressor blades

Illustratively, the actual power consumption of the compressor may satisfy the following relationship:

Q₁＝t₁×P₁

wherein Q is₁Representing the actual power consumption of the compressor; t is t₁Represents the accumulated operation time of the compressor; p₁Representing the power of the compressor. Exemplary, P₁May be determined according to the model of the compressor provided in the dryer.

For example, if the controller obtains the power of the compressor to be 0.1 kilowatt, the cumulative operating time of the compressor is 30 minutes, i.e. t₁30 min-0.5 h, P₁0.1 kw. The actual power consumption Q of the compressor₁0.1 × 0.5-0.05 kwh.

(2) Electric machine

Illustratively, the actual power consumption of the motor may satisfy the following relationship:

Q₂＝t₂×P₂

wherein Q is₂Representing the actual power consumption of the motor; t is t₂Representing the accumulated running time of the motor; p₂Representing the power of the motor. Exemplary, P₂May be determined according to a model of a motor provided in the dryer.

In addition, since the motor is periodically and intermittently operated, the controller may determine T according to the actual operation time period T of the dryer and the rotation/stop ratio X of the motor₂。

The rotation-stop ratio of the motor refers to a ratio of a rotation time length of the motor to a total time length of an operation period of the motor in one operation period.

For example, the accumulated operating time of the motor may satisfy the following relationship:

t₂＝T×X

for example, if the actual operation time period of the dryer is 50 minutes and the rotation/stop ratio X of the motor is 60% during the execution of the drying process, the accumulated operation time period of the motor is₂Is t₂50 minutes × 60% 30 minutes.

(3) Drying fan

Illustratively, during the execution of the drying program, t₄May be an actual operation time period T of the dryer.

Illustratively, during the execution of the drying program, t₅May be an actual operation time period T of the dryer. P₅It is possible to perform the model determination of the heater provided in the dryer.

Further, in the course of the clothes drying program being operated by the clothes dryer, the controller may use the sum of the power consumptions of the respective target power consuming elements associated with the clothes drying program as the actual power consumption of the clothes drying program from the start time to the current time.

Illustratively, the target electrical components of the drying program include: compressor, motor, drying fan, drain pump and heater, then the power consumption of dryer satisfies following relation:

Q＝Q₁+Q₂+Q₃+Q₄+Q₅

wherein Q is the power consumption of the clothes dryer, Q₁Representing the actual power consumption of the compressor; q₂Representing the actual power consumption of the motor; q₃Representing the actual power consumption of the drying fan; q₄Representing the actual power consumption of the drain pump; q₅Representing the actual power consumption of the heater.

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

In one example, the clothes dryers comprise voice reminding devices, and after the current actual power consumption is calculated, the controller can control the clothes dryer to broadcast 'current used electricity is 1 degree' or other similar reminding information. Or, if the plurality of clothes dryers include the display device, the controller may control the display device to display the calculated current actual power consumption for operating the clothes drying program after calculating the current actual power consumption, so as to facilitate viewing by the user.

In another example, several clothes dryers are in the smart home system as shown in fig. 2, and after calculating the current actual power consumption, the clothes dryer may send a notification instruction to the electronic device through the server, so that the electronic device may display the current actual power consumption for running the clothes drying program. Therefore, the user does not need to check the actual power consumption beside the clothes dryer, and the actual power consumption of the clothes dryer can be known remotely and in real time through the electronic equipment.

In some embodiments, the controller may control the dryer to issue a warning message that the power consumption exceeds a preset maximum power consumption when the current actual power consumption is greater than the preset maximum power consumption.

For example, when the current actual power consumption is greater than the preset maximum power consumption, the controller of the clothes dryer may control the clothes dryer to send out a warning message that the power consumption exceeds the standard in a manner of broadcasting a warning voice, broadcasting a warning sound, or displaying a warning text on a display device.

Or the controller of the clothes dryer can control the clothes dryer to send the reminding message through the server or directly to the electronic equipment, so that the electronic equipment can send the reminding message that the power consumption exceeds the standard.

And S1012, the controller determines the predicted power consumption of the clothes drying program according to the actual power consumption and the target of the clothes drying program.

In some embodiments, the target of the drying program may be that the dryer continuously dries the laundry for a target length of time. A drying program based on this goal may be referred to as a "timed dry" drying program. When the clothes dryer executes the timing drying program, the clothes dryer can continuously work until the working time reaches the preset target time.

Optionally, the target duration may be a preset operation duration of the dryer (for example, the standard mode of the dryer may be a fixed operation duration), or may be an operation duration set by a user (for example, a timing mode of the dryer).

In other embodiments, the drying process may be targeted to dry the laundry to a target humidity value. The drying process based on this goal may be referred to as a "stop-and-go-dry" drying process, and the dryer continues to operate while performing the "stop-and-go-dry" drying process until the current humidity of the drying drum (or the clothes in the drying drum) reaches the target humidity.

Alternatively, the target humidity may be a preset humidity value of the dryer (for example, a clothes drying stop mode of the dryer) or a target humidity value set by a user.

The embodiment provides a method for calculating and predicting power consumption, wherein a controller of a clothes dryer can calculate actual power consumption of each target power consumption element corresponding to a clothes drying program respectively, and the sum of the actual power consumption of each target power consumption element is used as actual power consumption of an operation clothes drying program, so that the actual power consumption of the operation clothes drying program can be calculated more accurately. The controller can thus further determine the predicted power consumption of the drying program based on the calculated actual power consumption.

As a possible implementation manner, for the "time drying" clothes drying procedure, based on the embodiment shown in fig. 4, as shown in fig. 5, the step S1012 may be specifically implemented as:

s10121, if the plurality of clothes drying programs are targeted to continuously dry the clothes within the target time period, the controller obtains the running time period of the clothes drying program from the starting time to the current time.

The controller can acquire the running time of the clothes drying program from the starting time to the current time through the timing device of the clothes dryer.

In addition, for the specific steps of determining the actual power consumption of the clothes drying program from the starting time to the current time, reference may be made to the related description in step S1011, and details are not repeated here.

S10122, the controller determines the remaining operation time length according to the target time length and the operated time length.

The controller can obtain the target duration of the clothes drying program from the operation parameters corresponding to the clothes drying program.

In addition, the remaining operation time is the time from the current time to the end time of the clothes drying program operated by the clothes dryer.

Illustratively, the remaining operation time length satisfies the following relationship:

remaining operating time length is equal to target time length-operating time length

S10123, the controller determines the predicted power consumption of the clothes drying program according to the running time, the actual power consumption and the residual running time.

It should be noted that the predicted power consumption is the total power consumption that may be consumed by the dryer to complete the drying procedure, that is, the power consumption of the dryer to always control the target power consumption elements to operate according to the control parameters of the target power consumption elements corresponding to the drying procedure from the starting time to the ending time of the drying procedure. The actual power consumption is the power consumption of the dryer control target power consumption elements which are operated according to the control parameters of the target power consumption elements corresponding to the drying program from the starting time of the drying program to the current time.

It is assumed that the dryer still controls the target power utilization elements to operate according to the control parameters of the target power utilization elements corresponding to the drying program within the remaining operation time of the drying program. The controller may infer the remaining power consumption required to complete the drying program based on the actual power consumption, and the elapsed operating time and the remaining operating 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 process.

Further, the sum of the actual power consumption and the estimated remaining power consumption is the predicted power consumption for completing the drying process.

Illustratively, the predicted power consumption may satisfy the following relationship:

the above-described embodiments provide a method of calculating a predicted power consumption based on an actual power consumption, and a controller of a clothes dryer may determine the predicted power consumption of a clothes drying program based on an operated time period, the actual power consumption, and a remaining operating time period in a case where a target of the clothes drying program is to continuously dry clothes for a target time period.

As another possible implementation manner, for the "stop-as-you-go" drying procedure, based on the embodiment shown in fig. 4, as shown in fig. 6, the step S1012 may be specifically implemented as:

s10124, if the plurality of clothes drying processes are targeted to dry the clothes to a target humidity value, the controller obtains a current humidity value detected by the humidity sensor at the current time and an initial humidity value detected at the beginning of the clothes drying process.

The controller may obtain the target humidity value of the drying program from the operation parameters corresponding to the drying program.

S10125, the controller determines a first humidity difference value according to the current humidity value and the initial humidity value.

Wherein the first humidity difference value is a difference value between the initial humidity value and the current humidity value.

S10126, the controller determines a second humidity difference value according to the current humidity value and the target humidity value.

And the second humidity difference value is the difference value between the current humidity value and the target humidity value.

S10127, the controller determines the predicted power consumption of the clothes drying program according to the actual power consumption, the first humidity difference value and the second humidity difference value.

It should be noted that the predicted power consumption is the total power consumption that may be consumed by the dryer to perform the drying process, that is, the power consumption required by the dryer in the process of the humidity value detected by the humidity sensor being changed from the initial humidity value to the target humidity value.

It is assumed that the dryer always controls the target power utilization elements to operate according to the control parameters of the target power utilization elements corresponding to the drying program from the starting time to the ending time of the drying program. The actual power consumption amount is a power consumption amount required by the dryer in a process in which the humidity value detected by the humidity sensor is converted from the initial humidity value to the current humidity value. Therefore, the controller can estimate the residual power consumption required for completing the clothes drying program according to the actual power consumption and the first humidity difference and the second humidity difference. The remaining power consumption is the power consumption required by the dryer in the process of converting the humidity value detected by the humidity sensor from the current humidity value to the target humidity value.

Illustratively, the predicted power consumption of the clothes drying program satisfies the following relationship:

in the embodiment of the application, the power consumption can be accurately determined and predicted according to the target of the clothes drying program in two situations.

The above embodiment provides another method for calculating predicted power consumption according to actual power consumption, in a case that a target of a drying program is to dry laundry to a target humidity value, a controller of a clothes dryer may calculate a first humidity difference value and a second humidity difference value, and further determine the predicted power consumption of the drying program according to the actual power consumption, the first humidity difference value and the second humidity difference value.
