For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural. The terms "first," "second," and the like, herein, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
The control method and apparatus of the washing machine of the present application will be described with reference to specific examples.
First, a control method of a washing machine according to an embodiment of the present application will be described.
Fig. 1 is a flowchart of a control method of a washing machine according to an embodiment of the present application. The execution body of the embodiment may be a washing machine control device, which may be implemented in hardware or software, and the washing machine control device may be a washing machine or may be a part of a washing machine. Referring to fig. 1, the method of the present embodiment includes:
step S101, in the dehydration process of the washing machine, dehydration parameters are obtained, wherein the dehydration parameters comprise the dehydration speed and the input voltage of a motor of the washing machine.
In particular, during washing of laundry by the washing machine, the washing machine may wash the laundry in a mode set by a user. After entering the dehydration phase, the washing machine control device acquires the dehydration parameters. The dehydration parameters include at least a dehydration speed and an input voltage of a motor of the washing machine.
Optionally, a voltage acquisition circuit may be provided in the washing machine, and the washing machine control device obtains the input voltage of the input motor according to the signal of the input voltage of the motor of the washing machine acquired by the voltage acquisition circuit. The voltage acquisition circuit may or may not be part of the control device of the washing machine.
Optionally, a speed sensor may be further provided in the washing machine, and the washing machine control device acquires the dehydration speed from the speed sensor. The dewatering speed can also be obtained by other methods, which are not limited in this embodiment.
Step S102, determining the dehydration extension time according to the dehydration parameters.
Specifically, the dehydration period required to be prolonged on the basis of the original dehydration period is determined according to the dehydration parameters. For example, a shorter dehydration extension period is determined when the input voltage of the motor is lower than the minimum voltage in the preset voltage range and/or when the dehydration speed is lower than the minimum speed in the first speed range, and a longer dehydration extension period is determined when the input voltage of the motor is lower than the minimum voltage in the preset voltage range and/or when the dehydration speed is lower than the minimum speed in the first speed range.
The minimum voltage in the preset voltage range may be the rated input voltage of the motor minus a first preset value, and the maximum voltage in the preset voltage range may be the rated input voltage of the motor plus a second preset value, where the first preset value and the second preset value may be the same or different. For example, the first preset value may be any value between 5 and 10, and the second preset value may be any value between 5 and 10. The first speed range may be a dehydration speed range corresponding to a current washing mode, i.e., a dehydration speed range in the current washing mode set when the washing machine leaves the factory.
It will be appreciated that if the input voltage of the motor currently obtained belongs to the preset voltage range, the currently obtained speed should belong to the first speed range unless the rotating structure of the motor fails, because the dehydration speed range in the current washing mode set at the time of leaving the laundry of the washing machine is the first speed range when the input voltage of the motor belongs to the preset voltage range. That is, in the case where there is no malfunction in the rotational structure of the motor and the input voltage of the motor currently acquired belongs to the preset voltage range, the dehydration extension period may be determined to be 0s.
Step S103, determining the total dehydration time length according to the dehydration extension time length and the original dehydration time length, wherein the original dehydration time length is the dehydration time length set by a user.
One method for setting the dehydration period by the user is that the user directly sets the dehydration period, such as the user inputs the dehydration period. The user can input the dehydration time through voice, can input the dehydration time through clicking a button on the interface of the washing machine, and can input the dehydration time in an input box of the interface of the washing machine.
Another method for the user to set the dehydration period is for the user to set the dehydration period indirectly. For example, the user sets a current washing mode, the current washing mode corresponds to a dehydration time length, and the dehydration time length corresponding to the current washing mode is the dehydration time length indirectly set by the user.
For the determination of the total dehydration period, in one arrangement, determining the total dehydration period from the dehydration extension period comprises: and obtaining the total dehydration time according to the sum of the dehydration extension time and the original dehydration time.
In another aspect, determining the total dehydration duration based on the extended dehydration duration includes:
and a1, pushing the dehydration extension time if the value of the dehydration extension time is larger than a second value, so that a user confirms whether the dehydration extension time needs to be extended on the basis of the original dehydration time.
Wherein the second value may be any value between 0 and 60s, including 0s and 60s.
The pushing dehydration time length comprises the following steps: displaying dehydration extension time on a display screen of the washing machine, and giving out prompt tones; alternatively, pushing the dehydration for an extended period of time includes: broadcasting dehydration for a prolonged period of time; alternatively, pushing the dehydration for an extended period of time includes: and sending the dehydration extension time to the terminal equipment of the user so as to enable the terminal equipment of the user to display or broadcast the dehydration extension time.
In an alternative, the dewatering process may be suspended while the dewatering extension period is pushed, i.e. the dewatering speed is controlled to 0, so that the user knows the pushed dewatering extension period.
A2, if the confirmation information input by the user is received, or the pushing time of the dehydration extension time is taken as the starting time, and the information input by the user is not received within the preset time, obtaining the total dehydration time according to the sum of the dehydration extension time and the original dehydration time.
If the non-confirmation information that the rejection input by the user prolongs the dehydration time period is received, the original dehydration time period is determined to be the total dehydration time period.
In the embodiment, the dehydration parameters are obtained in the dehydration process of the washing machine, and the dehydration parameters at least comprise the dehydration speed and the input voltage of the motor of the washing machine; determining dehydration extension time according to the dehydration parameters; and determining the total dehydration time according to the dehydration extension time and the original dehydration time, wherein the original dehydration time is the dehydration time set by a user. The method of the embodiment adjusts the dehydration time by acquiring the dehydration parameters, namely, ensures the dehydration effect of the washing machine on the clothes by ensuring enough dehydration time.
The specific implementation of the above embodiment will be described in detail below by way of the embodiment shown in fig. 2 and 3.
Fig. 2 is a flowchart of a control method of a washing machine according to an embodiment of the present application. Referring to fig. 2, the method of the present embodiment includes:
step S201, in the dehydration process of the washing machine, the dehydration speed and the input voltage of the motor of the washing machine are obtained.
The order of acquiring the input voltage and the dehydration speed of the motor of the washing machine is not limited, and the input voltage and the dehydration speed may be acquired simultaneously or sequentially.
Step S202, determining dehydration extension time according to the dehydration parameters and the corresponding relation; the corresponding relation comprises a plurality of groups of preset dehydration parameters, and the dehydration extension time corresponding to each group of preset dehydration parameters, wherein each group of preset dehydration parameters comprises a preselected input voltage range and a preselected dehydration speed range.
Wherein, there are one or more sets of preset dehydration parameters including a pre-selected input voltage range of a preset voltage range in the corresponding relation sets of preset dehydration parameters, and one or more sets of preset dehydration parameters including a pre-selected dehydration speed range of a first speed range in the corresponding relation sets of preset dehydration parameters. The preset voltage range and the first speed range have the same meaning as the embodiment shown in fig. 1.
It is understood that the dehydration extension time length corresponding to one or more groups of preset dehydration parameters excluding the preset voltage range in the corresponding relationship is greater than 0, and the dehydration extension time length corresponding to one or more groups of preset dehydration parameters excluding the first speed range in the corresponding relationship is greater than 0.
In particular, since the speed ranges corresponding to different washing modes may be different, a correspondence relationship for the extended period of time for dehydration in each washing mode may be stored in the washing machine.
Optionally, before step S202, the method may further include: and determining that the input voltage of the motor which is currently acquired is smaller than the minimum voltage in the preset voltage range. When the input voltage of the motor which is acquired currently is determined to be smaller than the minimum voltage in the preset voltage range, the dehydration extension time is determined according to the dehydration parameters and the corresponding relation. Since the dehydration extension period needs to be determined according to which voltage range the input voltage of the motor currently acquired is in when the input voltage of the motor is smaller than the minimum voltage among the preset voltage ranges, the dehydration extension period needs to be determined according to the dehydration parameters and the correspondence.
Optionally, before step S202, the method may further include: it is determined that the dewatering speed is lower than the minimum speed in the first speed range. That is, when it is determined that the currently acquired dehydration speed is lower than the minimum speed in the first speed range, the dehydration extension period is determined according to the dehydration parameters and the correspondence. Since the dehydration extension period needs to be determined according to which speed range the currently acquired dehydration speed is in when the dehydration speed is lower than the minimum speed in the first speed range, the dehydration extension period needs to be determined according to the dehydration parameters and the correspondence.
Corresponding to at least one of the two alternatives, when it is determined that the input voltage of the motor currently acquired belongs to the preset voltage range and the dehydration speed currently acquired belongs to the first speed range, it may be directly determined that the dehydration extension time period is 0.
It can be understood that when the two alternatives are not present, in this embodiment, after the input voltage and the dehydration speed of the motor are obtained, the dehydration extension period is determined according to the dehydration parameters and the correspondence.
Specifically, determining the dehydration extension period according to the dehydration parameters and the correspondence may include: determining that the input voltage of the motor currently acquired belongs to a first preselected input voltage range in a plurality of preselected input voltage ranges, determining that the dehydration speed of the motor currently acquired belongs to a first preselected dehydration speed range in a plurality of dehydration speed ranges, and determining that the dehydration extension time corresponding to a set of dehydration parameters including the first preselected input voltage range and the first preselected dehydration speed range in the corresponding relation is the finally determined dehydration extension time.
Further, the corresponding relation includes a plurality of groups of preset dehydration parameters, and the minimum input voltage included in the plurality of groups of preset dehydration parameters is greater than or equal to a target voltage, wherein the target voltage is the lowest voltage at which the motor can work. It can be understood that the washing machine is controlled to stop operating if the input voltage of the motor currently obtained is lower than the target voltage.
Step S203, determining the total dehydration duration according to the dehydration extension duration and the original dehydration duration.
The specific implementation of this step is referred to step S103 in the embodiment shown in fig. 1, and will not be described here again.
The method of the embodiment adjusts the dehydration time by acquiring the dehydration parameters, namely, ensures the dehydration effect of the washing machine on the clothes by ensuring enough dehydration time. And the method has higher efficiency of obtaining the total dehydration time.
Fig. 3 is a flowchart III of a control method of a washing machine according to an embodiment of the present application. Referring to fig. 3, the method of the present embodiment includes:
step S301, during the dehydration process of the washing machine, the input voltage of the motor of the washing machine is obtained.
Step S302, determining that the input voltage of the motor is lower than the minimum voltage in the preset voltage range, and increasing the rotation speed of the motor.
The preset voltage range in this embodiment has the same meaning as the embodiment shown in fig. 1.
When the input voltage of the motor which is acquired currently is determined to be lower than the minimum voltage in the preset voltages, the input voltage of the motor is indicated to be lower. When the input voltage of the motor is lower, the rotation speed of the motor is also reduced, so that the dehydration speed is reduced, and the dehydration effect is affected.
In one aspect, increasing the rotational speed of the motor when the maximum speed at which the motor is currently capable of rotating is greater than or equal to the target speed includes: the rotational speed of the motor is increased to a target speed, which is the rotational speed of the motor that enables the dehydration speed of the washing machine to fall within a first speed range, which is defined as in the embodiment shown in fig. 1. At this time, after the rotational speed of the motor increases in step S303, the obtained dehydration speed of the motor belongs to the first speed range.
And when the maximum speed of the motor which can rotate at present is smaller than the target speed, increasing the rotating speed of the motor, and increasing the rotating speed of the motor to the maximum speed of the motor which can rotate at present. At this time, after the rotational speed of the motor is increased in step S303, the obtained dehydration speed of the motor is less than the minimum speed in the first speed range.
Step S303, after the rotation speed of the motor is increased, the dehydration speed is obtained.
Step S304, determining dehydration extension time according to the dehydration parameters and the corresponding relation; the corresponding relation comprises a plurality of groups of preset dehydration parameters, and the dehydration extension time corresponding to each group of preset dehydration parameters, wherein each group of preset dehydration parameters comprises a preselected input voltage range and a preselected dehydration speed range.
The description of the correspondence relationship in this embodiment is the same as that in the embodiment shown in fig. 2, and will not be repeated here. The specific implementation of this step refers to the specific implementation of step S202 in the embodiment shown in fig. 2, and will not be described here again.
The method of the embodiment adjusts the dehydration time by acquiring the dehydration parameters, namely, ensures the dehydration effect of the washing machine on the clothes by ensuring enough dehydration time. Meanwhile, the dehydration extension time is determined by the dehydration speed obtained after the rotation speed is adjusted, so that the determined dehydration extension time is relatively smaller, the washing efficiency is improved, and the dehydration energy consumption is reduced.
The control method of the washing machine provided by the application is described in detail above, and the device and the equipment provided by the application are described below.
