In some cases, the user may not know how much the washing time is set to be appropriate. If the setting is not proper, the whole washing process may be too long, or the clothes may not be washed cleanly. In addition, the user sets the relevant parameters after selecting the program every time the washing machine is used, and the operation is not simple and is troublesome.
For the user, much attention is paid to how long the program selected by the user can wash the clothes, and the user cannot wash the clothes completely. The clothes can not be washed clean, and the washing time and the heating time play a great role.
The total time required for the washing machine to operate a washing course is determined by parameters such as washing time, water heating temperature, rinsing times, etc. The current washing machines on the market need to adjust the total washing time by adjusting parameters such as washing time, water heating temperature, rinsing times and the like. When the time requirement of a user is high, for example, the user goes out after 40 minutes, the user also wants to wash and dry clothes before going out, after the washing machine is opened, the total time displayed by a program is about 70 minutes, the time needs to be shortened, the time needs to be about 40 minutes indirectly by adjusting parameters such as washing time, water heating temperature and rinsing times, and a set of parameters contained in the adjusted 40 minutes is not necessarily optimal, so that the clothes are not washed cleanly, can not be rinsed cleanly, contain too much water after being dehydrated, and are not easy to dry.
The present invention has been made in view of this situation.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a washing machine control method which determines the total washing time by a user and automatically configures parameters of each washing stage of the washing machine.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used for illustrating the present invention and are not intended to limit the scope of the present invention.
For the user, much attention is paid to how long the program selected by the user can wash the clothes, and the user cannot wash the clothes completely. Whether the laundry can be washed clean or not depends mainly on the washing time and the heating time. In the existing washing machine program, after the user selects the relevant program, parameters such as rinsing times, dehydration rotating speed, drying non-drying and the like need to be set. Some washing machines can also modify the washing time by the user, but in some cases, the user does not know how much the washing time is set to be appropriate, and if the set washing time is not appropriate, the whole washing process may be too long, or the laundry may not be washed cleanly. In addition, the user selects the program and then sets the relevant parameters when using the washing machine every time, and the operation is not simple and troublesome.
The washing machine of the invention has a normal washing mode and a time washing mode, wherein the normal washing mode is a control mode of the existing washing machine, and the time washing mode is an added control mode of the invention. In a conventional washing mode, a user selects a corresponding program according to the requirement of the user, and washing is executed by adopting the default set parameters of the program, or washing time, water heating temperature, rinsing times and dehydration time are modified under the current program, and functions of drying, soaking and the like are selected, and then washing is executed according to the modified parameters; after the user sets the corresponding parameters, the program calculates the total time and converts the total time into the remaining time to display, namely how long the program needs to be completed.
In the time washing mode, the user determines the total washing time, the washing machine automatically adjusts parameters according to the total washing time, and determines the final main washing time without selecting the main washing time or selecting additional functions by the user. When the user selects the additional function or adjusts the parameters, the washing machine prompts the user and exits the time washing mode, and the regular washing mode is performed.
The default mode of the washing machine is a conventional washing mode, the time washing mode is an off state, the time washing mode can be selected to enter the time washing mode in the process that a user sets parameters or selects additional functions before washing is not started in the conventional washing mode, and at the moment, the parameters set by the user in the conventional washing mode and the selected additional functions are invalid.
As shown in fig. 1, the method for controlling a washing machine according to the present invention comprises, after the washing machine is turned on and laundry is put in, specifically,
s1, starting a time washing mode;
s2, selecting a program and determining the total washing time;
s3, automatically configuring the execution parameters of each stage of the washing process of the washing machine, wherein the execution parameters comprise at least one parameter of washing time, rinsing times and dehydration time;
s4, starting washing.
Example one
In this embodiment, in the time washing mode, different programs of the washing machine are set with different total washing times, for example, the display of cotton and linen: off, 50 to 180, the shirt shows: off, 30 to 90, etc., wherein "off" in each program refers to off time wash mode. The user selects the program first and then selects the total washing time corresponding to the program, or the user freely inputs the time within the total washing time range of each program preset by the washing machine.
Each program capable of realizing the time washing mode correspondingly displays the default total washing time, and a user selects the program to start washing and directly executes the program according to the default operation parameters corresponding to the default total washing time of the program.
For example, if a shirt program is selected, washing is carried out for 60 minutes in the default time, the displayed remaining time is also 60 minutes, parameters such as washing time, rinsing times, dewatering time, default heating temperature and rotating speed and the like are preset in the washing machine corresponding to the 60 minute program, the general shirt program has no additional programs such as drying, additional functions, special stains, disinfectants and the like in the default mode, the detergent is automatically added, and the rotation and stop ratio of the conventional shirt washing program is adopted.
Example two
In this embodiment, the washing machine has different total washing time intervals and corresponding execution parameters of each stage of the washing process, in step S3, the washing machine determines the preset interval in which the washing machine is located according to the total washing time input by the user, and calls the execution parameter corresponding to the preset interval, and if the total washing time input by the user is different from the default total washing time in the preset interval, the washing machine needs to adjust the washing time to reach the determined total washing time.
For example: under the shirt program, if the user determines that the total washing time is 65 minutes, the washing machine presets 60-70 minutes as a total washing time interval, and defaults to execute a parameter corresponding to the total washing time of 60 minutes in the interval, at the moment, the washing machine adjusts the main washing time on the basis of the total washing time of 60 minutes, so that the final total washing time is 65 minutes.
However, if the user determines that the total shirt washing time is 85 minutes and is not within the preset interval of the total shirt washing time of 60-70 minutes, the default rinsing times, the dewatering time, the heating temperature and the dewatering time of the program are different from the time washing of 65 minutes.
EXAMPLE III
In this embodiment, the control method of the washing machine of the present invention is that a user puts in clothes, selects a washing program "shirt", determines that the total washing time is 60 minutes, and then weighs the clothes to obtain a weighing value, and the program adjusts corresponding parameters according to the weighing value, and the weighing value determines the heating time, because different clothes amounts correspond to different water inflow amounts, and different water inflow amounts are heated to default heating temperatures and have different heating times.
After the user selects 'shirt' and determines that the total washing time is 60 minutes, the washing machine allocates default rinsing times, default dewatering time and the weight value, and determines the optimal heating time corresponding to the clothes quantities at the default heating temperature. And after the rinsing times are determined, determining the rinsing time, wherein the washing time comprises main washing time and heating time, and after the total washing time is fixed, the main parameter of the washing machine adjusted in the time washing mode is the main washing time.
Example four
As shown in fig. 2, in the present embodiment, if the user selects time washing "shirt" for 60 minutes, the amount of laundry put into the washing machine increases. The program assigns a default number of rinses, a default spin time. As the amount of laundry increases, the corresponding heating time is positively changed. At this time, the default heating time of the program is changed, the latest heating time is adjusted according to the weighing value, and then the main washing time is automatically distributed, so that the final total washing time is 60 minutes.
If a user puts a lot of clothes, the heating time corresponding to the weighing value exceeds the main washing time automatically distributed, at the moment, the program starts to adjust the default rinsing times, and the rest times are unchanged; if not, continuously adjusting the default dehydration time; until the appropriate main wash time can be automatically dispensed. Further, if the amount of the laundry is increased more, and the heating time still exceeds the main washing time allocated last after the adjustment, the time washing mode is exited and the conventional washing mode is entered.
EXAMPLE five
The time washing in the washing machine of the invention is a single washing mode, the default control mode is normal washing, and the time washing mode is an off state. Further, the user can also select whether the time washing mode is closed or opened, if the user defaults to be closed, the user defaults to enter the professional washing mode, if the user selects time washing, the user enters the time washing mode, and if the user selects time washing to be closed, the user cannot enter the time washing mode.
After the user selects the time, the original functions of the programs such as appointment, temperature, rotating speed, rinsing times, drying, special soaking and the like can be selected continuously, if the functions are selected again, the displayed remaining time, namely the determined total time of washing and washing the clothes in the time is adjusted according to the selection of the functions, and meanwhile, the washing machine prompts the user, such as prompting: changing this parameter will exit the time wash.
For example, in the time washing mode, the total washing time under the shirt program is determined to be 60 minutes, that is, the displayed remaining time is 60 minutes, if the user adjusts to increase one time of rinsing, the remaining time is changed to 72 minutes, at this time, the time washing mode is exited, and the time washing mode is closed; if the rinsing is reduced once, the residual time is changed to 48 minutes, the time washing is still exited, and the time washing mode is closed.
Further, if time washing is not selected at first, but in a default normal washing mode, the remaining time is displayed as 96 minutes by setting various parameters, and if time washing is selected for 60 minutes again, the previous setting in the normal washing mode is cancelled, and the setting parameter of the total washing time of 60 minutes under the program is called directly. Preferably, the user is prompted to select a time wash and the other set parameters are cancelled.
Furthermore, the current programs of the drum washing machine are various, but not all programs are suitable for time washing, so the programs suitable for time washing are limited, and only part of programs can select time washing. For example, a single rinse or single spin program is selected, and since there is no main wash time, the time wash is disabled, i.e., the program with the default main wash time of 0 cannot select the time wash. In addition, after the time is selected, the main washing time allocated to the washing machine cannot be 0.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
