In order to facilitate those skilled in the art to understand the program recommendation control method of the present invention, the washing machine 1 of the present invention will be briefly described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, the washing machine 1 of the present invention is provided with a controller 11, a display screen 12 and a communication module 13. Wherein, the controller 11 is respectively communicatively connected with the display screen 12 and the communication module 13, and the communication connection is preferably a wired connection. The controller 11 is used to receive and recognize the instruction issued by the user, and then control the washing machine 1 to perform the corresponding operation according to the instruction. The display screen 12 is used to display the laundry treatment program, operating parameters, operating status and other information of the washing machine 1. The communication module 13 is used to realize the communication connection between the controller 11 and the server 2 so that the controller 11 and the server 2 can perform information interaction.

Those skilled in the art can understand that the controller 11 may include one functional module, or may include multiple functional modules. In addition, when the controller 11 includes multiple functional modules, the multiple functional modules may be independent functional modules or integrated functional modules; they may be physical functional modules or virtual functions. Module.

Although not explicitly shown in the figure, the controller 11 and the communication module 13 are provided in the cabinet of the washing machine 1 and fixedly connected to the cabinet. The display screen 12 is provided on the operation panel of the washing machine 1.

As shown in FIG. 2, a start / tentative key 121 is displayed on the display screen 12 of the present invention. In addition, a person skilled in the art may also set the start / tentative key 121 as a physical physical key as needed, and set it at another location on the washing machine.

As shown in FIG. 3, the program recommendation control method of the present invention mainly includes:

Step S100, obtaining the start-up time of the washing machine 1;

Step S200: Determine a preset corresponding time period according to the boot time;

Step S300, displaying at least one laundry treatment program with a higher historical running frequency in a preset corresponding period currently;

In step S400, the displayed laundry treatment program is selectively executed.

Among them, step S400 is an optional step for the program recommendation control method of the present invention.

Specifically, in step S100, when the power-on button on the washing machine 1 is operated, the washing machine 1 is turned on, and thus the controller 11 obtains the turning-on instruction of the washing machine 1. The controller 11 obtains the current time from the server 2 or from the time device of the washing machine 1 itself, and the current time is the start-up time of the washing machine 1. For example, the boot time is 7:50 in the morning on Monday.

It should be noted that the time information walked on the server 2 or the time device includes the date and time of the time zone or country where the washing machine 1 is located.

A person skilled in the art can understand that, in another feasible embodiment of the present invention, the washing machine 1 can also be set to be in a sleep state in a normal state and activated when the power-on button is operated. In this embodiment, the controller 11 detects the activation instruction of the washing machine 1 in real time, and records the current time when the washing machine 1 is activated to determine the start-up time of the washing machine 1.

Specifically, in step S200, the controller 11 determines the currently corresponding preset time period according to the power-on time.

Wherein, in a preferred embodiment of the present invention, the preset time period includes a working day period and a non-working day period. Further, the working day period includes three sub-periods of morning, noon and evening; the non-working day period includes three sub-periods of morning, noon and evening. Based on this, step S200 is specifically that the controller 11 determines whether the current time is morning, noon or evening on a working day or morning, noon or evening on a non-working day according to the start-up time.

In addition, in another feasible embodiment of the present invention, a person skilled in the art may also set the preset time period to any other feasible time period as needed. For example, each day, whether it is a working day or a non-working day, is divided into three sub-periods of morning, noon, and evening. As another example, each day is divided into two periods of day and night.

Those skilled in the art can understand that the three periods of morning, noon and evening in the present invention can be divided at any feasible time. For example, from 0 to 9 in the morning; from 9 to 16 at noon; from 16 to 24 at night. Similarly, the day and night mentioned in the present invention can also be divided at any feasible time. For example, 8 to 20 is daytime, and 20 to 8 is night.

Specifically, in step S300, the controller 11 acquires the historical operating frequency of each laundry treatment program corresponding to the period according to the determined preset period. Then the controller 11 displays at least one laundry treatment program with a higher (larger) historical operating frequency on the display screen 12.

As shown in FIG. 2, in the preferred embodiment of the present invention, three laundry treatment programs are displayed on the display screen 12, and the three laundry treatment programs are arranged in order according to the historical running frequency: mixing, quick washing, and single spin .

In another feasible embodiment of the present invention, a person skilled in the art may also make the display screen 12 display other numbers of laundry treatment programs according to the historical running frequency according to needs. The number can be one, two, four, etc. Exemplarily, the display screen 12 displays only one laundry treatment program with the highest operating frequency in history—mixing.

Specifically, in step S400, the controller 11 detects the user's manipulation instruction in real time, and selectively executes the displayed laundry treatment program according to the detected result.

The following describes step S400 with reference to FIG. 2.

When the controller 11 detects that the user directly operates the start / pause key, the controller 11 causes the washing machine 1 to execute the displayed laundry processing program—mixing, which has the highest historical operation frequency. When the controller 11 detects that the user has selected quick wash or single spin, and then operates the start / pause key, the controller 11 causes the washing machine 1 to execute a laundry treatment program—quick wash or single spin.

In addition, a person skilled in the art may, as required, after the controller 11 executes step S300, cause the washing machine 1 to directly perform the corresponding operation according to the displayed laundry processing program with the highest historical execution frequency—mixing.

Further, although not shown in the figure, the program recommendation control method of the present invention further includes steps:

The controller 11 records the laundry processing program of the washing machine 1 this time, and updates the historical operation information of the washing machine 1.

A person skilled in the art can understand that any of the above steps S100 to S300 can be executed on the washing machine 1 (specifically, the controller 11), or on the server 2. When the server 2 executes the above steps, the cost of the controller 11 on the washing machine 1 can be reduced. For example, the controller 11 can ban functional modules such as the storage module, the processing module, and the comparison module accordingly, simplifying the function and structure of the controller 11. In order to establish an independent communication relationship between the washing machine 1 and the server 2, it is necessary to register a corresponding account on the server 2 and bind the identity information of the washing machine 1 to the account.

The following describes the program recommendation control method of the present invention with reference to FIGS. 4 to 7.

As shown in FIG. 4, the historical operation information of the washing machine 1 in the past year is counted in advance. That is, in the past 1 year, the number of uses of each laundry treatment program in each preset time period is counted.

As shown in FIG. 5, according to the statistical results in FIG. 4, the frequency of use of each laundry treatment program in each preset period is calculated.

As shown in FIG. 6, a laundry treatment program with the highest usage frequency in each preset period is selected and recommended to the user, and displayed on the display screen 12. As shown in FIG. 6, the laundry treatment program recommended and displayed in the morning on weekdays is quick wash; the laundry treatment program recommended and displayed in the noon on weekdays is quick wash; the laundry treatment program recommended and displayed in the evening on weekdays is Quick wash; the laundry treatment program recommended and displayed on the morning of non-working days is mixed; the laundry treatment program recommended and displayed on the noon of non-working days is mixed; the laundry treatment program recommended and displayed on the evening of non-working days is quick washing.

As shown in FIG. 7, the three most frequently used laundry treatment programs in each preset period are selected and recommended to the user, and displayed on the display screen 12. As shown in FIG. 7, the laundry treatment programs recommended and displayed in the morning on weekdays are quick wash, mixing and single spin; the laundry treatment programs recommended and displayed at noon on weekdays are quick wash, mix and single spin; weekdays The recommended and displayed laundry treatment programs for the evening are quick wash, mix and silk; the recommended and displayed laundry treatment programs for the non-working day morning are mixing, single spin and quick wash; the recommended and displayed laundry treatment programs for the non-working day noon It is mixing, quick washing and single dehydration; the laundry treatment program recommended and displayed at night on non-working days is quick washing, mixing and single dehydration.

In addition, in order to facilitate the user's use of the washing machine 1, a person skilled in the art may also preset or count the frequency of use of each laundry treatment program in each preset period of time as needed, and then store the washing machine 1 in the factory The controller 11 of the washing machine 1 or a corresponding storage module.

Based on the above description, those skilled in the art can understand that the present invention calculates the historical operating frequency of the washing machine 1 in each preset period in advance, and then after the washing machine 1 is turned on, makes the history corresponding to the preset period The one or more laundry treatment programs with the highest operating frequency are displayed on the display screen 12 and are recommended for use by the user. Therefore, the user only needs to browse a few laundry treatment programs on the display screen 12 to obtain the desired laundry treatment program, without turning the page on the display screen 12 to find the desired laundry treatment program. Therefore, the present invention facilitates the operation and use of the washing machine 1 by the user.

Finally, it should be noted that the historical operating frequency of each laundry treatment program in each preset period mentioned in the present invention refers to the actual historical operation of each laundry treatment program in each preset period Frequency (denoted as f ₀ ). Wherein, the actual historical operating frequency = (the number of times a certain laundry treatment program runs in the preset period) ÷ (the sum of the number of times all laundry treatment programs run in the preset period). For example, the actual historical running frequency of the quick wash program on the morning of the working day = (the number of times the quick wash program is run in the morning) ÷ (the sum of the number of times all laundry treatment programs are run in the morning)

However, due to the influence of other factors (such as the operating habits of different users), the laundry treatment program recommended to the user based on the actual historical operating frequency (f ₀ ) is often not the user's most desired.

For this reason, in another feasible embodiment of the present invention, which is different from the above preferred embodiment, this embodiment sets the historical operating frequency of each laundry treatment program in each preset time period to an estimated history Operating frequency (recorded as f _estimate ).

Wherein, f _estimate _{= f 0 * (1-k} ) + f * k _Total

Among them, f _estimate refers to the estimated historical running frequency of a certain laundry treatment program within a specific preset time period. For example, the estimated historical frequency of the quick wash program on the morning of the working day.

f ₀ refers to the actual historical running frequency of a certain laundry treatment program within a specific preset time period. For example, the actual historical running frequency of the quick wash program on the morning of the working day.

f _always refers to the actual historical frequency of a certain laundry treatment program in all preset time periods. For example, the actual historical running frequency of the quick wash program in all consecutive times.

k is the correction factor. Preferably, 0 <k ≦ 0.2; further preferably, k = 0.1. More preferably, k will continue to self-learn, optimize, and correct according to “the number of deviations of the laundry treatment program recommended by the washing machine 1 and the laundry program finally selected by the user”, so as to make the laundry treatment program recommended by the washing machine 1 more accurate. Illustratively, when a deviation occurs, the value of k is increased by 0.01.

So far, the technical solutions of the present invention have been described with reference to the preferred embodiments shown in the accompanying drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or replacements to the related technical features, and the technical solutions after these changes or replacements will fall within the protection scope of the present invention.
