The second moisture content D is a moisture content corresponding to the dehydration abnormality of the laundry, and the second moisture content D may be a factory set value of the washing machine, or a user set value, and preferably, a detection value of the washing machine.
The washing machine divides the interval from the step B to the step D into a plurality of intervals, each interval corresponds to a dehydration duration adjusting parameter lambda 2 and/or a dehydration rotating speed adjusting parameter mu 2, both lambda 2 and mu 2 are larger than 1, the washing machine determines the corresponding dehydration duration adjusting parameter lambda 2 and/or the corresponding dehydration rotating speed adjusting parameter mu 2 according to the interval where the clothes moisture content X is located, and correspondingly adjusts the dehydration parameters in the second dehydration process.
Wherein, the interval that moisture content is bigger, the corresponding regulating parameter is also bigger, just so can carry out the parameter of the second dehydration process of pertinence regulation to the clothing of different moisture contents, ensure ultimate dehydration effect.
Example eight
The present embodiment describes the washing machine in detail to obtain the moisture content of the laundry.
The washing machine acquires the dry weight of the laundry before water is supplied, acquires the moisture content of the laundry before a dehydration process is performed after water is drained, and the second water content ratio D is obtained by the following formula:
d ═ 100% by weight (W2-W1)/W1, W2 is the wet weight of the laundry, and W1 is the dry weight of the laundry.
The washing machine can acquire the dry weight of the clothes by identifying the electronic tag on the clothes to acquire the information of the clothes, and can also acquire the dry weight by directly controlling the motor to weigh. The manner in which the washing machine obtains the dry weight of the laundry includes, but is not limited to, weighing by a motor.
The washing machine comprises a motor, the motor is used for driving a washing barrel to rotate, and the washing machine determines the dry weight and the wet weight of clothes by weighing the load of the washing barrel. The washing machine can obtain the load weight of the washing barrel through the following three schemes:
the first scheme is that after the washing machine receives the first dewatering course, the washing machine stops rotating, then the motor is controlled to drive the washing tub from static to moving, the current required by the motor from static to rotating is detected, the larger the load weight is, the larger the driving current is, and the load weight can be obtained according to the detected driving current.
The second scheme is that at the end of the first dewatering course, the washing machine control motor stops suddenly from rotating, and the current or electromotive force generated by the inertia to continuously rotate and cut the magnetic induction lines is larger, so that the larger the load weight is, the larger the counter-driving potential is.
The third scheme is that at the end of the first dewatering course, the washing machine controls the motor to stop suddenly by rotation, records the time required for the motor to stop rotating, the larger the load weight is, the larger the inertia is, the longer the stop time is, therefore, the washing tub load weight can be determined according to the stop time.
In another solution, the washing machine comprises a weighing device that directly weighs the load of the washing tub. If a weighing device is arranged on a hanger rod of the washing machine, the weight of the inner barrel and the outer barrel of the washing machine is known, so that the weight of clothes can be obtained.
Example nine
And after the second dewatering process is finished, the washing machine detects the moisture content of the clothes again, judges whether the moisture content of the clothes is lower than a set value or not, if the judgment result is yes, the dewatering is finished, and if the judgment result is not, prompt information is sent.
Specifically, after the second dehydration process is finished, the washing machine detects the moisture content of the clothes again, judges whether the moisture content of the clothes is lower than a set value, if so, the washing machine controls the dehydration to be finished, otherwise, the washing machine executes a prompt process for prompting a user that the moisture content of the clothes does not reach the set value.
After the second dehydration process is finished, if the moisture content of the clothes is detected to be higher than the set value, the washing machine does not execute shutdown, but executes a prompt process, so that the unqualified clothes which are not dehydrated are provided with a chance for remedying.
In the prompting process, the washing machine receives a dehydration canceling instruction or detects that the cover body is opened, the control of the washing machine is finished, otherwise, the washing machine executes the dehydration process again after the prompting process is finished.
When the second dehydration process is finished and the moisture content of the clothes is detected to be higher than the set value, the washing machine defaults to the fact that the dehydration process needs to be executed once again, therefore, a waiting process is executed first, if the user selects to cancel the dehydration, or the user directly opens the cover body, the user gives up executing the dehydration process once again, at the moment, the control of the washing machine is finished, otherwise, the washing machine automatically executes the dehydration process after the prompt process is finished.
In the prompting process, the washing machine generates prompting information to prompt a user, the prompting mode can be voice prompting, or the prompting mode can be that an indicator lamp flickers, and a display screen displays prompting. When the user is remotely controlled through the intelligent terminal, the intelligent terminal can shake or prompt the user through voice.
Preferably, in the prompting process, the washing machine controls the display screen to display the current moisture content of the clothes, detects the trigger signal of the start key in real time, and controls the dewatering process to be executed when the trigger signal of the start key is detected.
In the scheme, the washing machine displays the moisture content in the prompting process, so that a user can conveniently judge whether to accept the moisture content, the user selects to accept the moisture content, an instruction for canceling the execution of the dehydration process is generated, and the user can directly trigger the starting key of the washing machine again, so that the washing machine executes the dehydration process once again, and the washing machine does not need to wait for the completion of the washing as early as possible after the prompting process is finished.
The washing machine comprises a plurality of dewatering keys/a plurality of dewatering icons displayed on the washing machine, each dewatering key/dewatering icon corresponds to a dewatering program, and when the washing machine senses that a certain dewatering key/dewatering icon is triggered, a corresponding dewatering process is executed in a dewatering stage. And each dehydration key or each dehydration icon represents a target water content, namely a corresponding set value after dehydration is finished, and whether a prompting process is executed or not is determined according to the relation between the actual water content and the set value.
Example ten
An embodiment ten provides a different solution from the ninth embodiment, in the tenth embodiment, after the dehydration stage of the washing machine is finished, the washing machine detects the moisture content of the clothes again, determines whether the deviation rate of the moisture content of the clothes from the set value is lower than the set deviation rate, if so, the control of the washing machine is finished, otherwise, the washing machine executes a prompt process for prompting a user that the moisture content of the clothes does not reach the standard.
In the embodiment, when the moisture content of the clothes is close to the set value, the clothes are considered to be qualified in dehydration, so that the probability of performing the dehydration process for the second time by the washing machine can be reduced, and the time and the energy are saved.
Further, the washing machine executes a prompt process with set duration, in the prompt process, the washing machine receives a dehydration instruction and executes the dehydration process, and in the prompt process, the washing machine does not receive the dehydration instruction or the washing machine detects that the cover body is opened, and the washing machine control is finished. And in the prompting process, the washing machine control display screen displays the current water content of the clothes and detects whether the start key is triggered or not, if so, the washing machine controls to execute the dehydration process, and if the start key is not triggered/the cover body is opened, the washing machine controls to finish.
The scheme of this embodiment is different from the ninth embodiment and is an alternative scheme.
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.
