The drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before describing embodiments of the present application, the terms and background are used herein to describe:
an intermediate stripping stage: when the washing machine executes the dewatering process, the inner drum of the washing machine is driven by the motor to be in a cyclic period of firstly rotating for several seconds and then stopping for several seconds, and the time length is generally 3 minutes (can be set according to actual requirements);
and (3) a continuous stripping stage: after the intermediate dewatering stage, the inner tub of the washing machine is driven by the motor to rotate continuously at certain frequency and the rest dewatering process is executed.
The washing machine, as a commonly used intelligent device for home life, has gradually replaced manual washing of clothes, and after the washing machine washes the clothes, the dehydration stage of the clothes is entered, and the dehydration stage is divided into an intermittent stage and a continuous stage, wherein the continuous stage is to remove moisture attached to the clothes after the intermittent stage to the maximum extent so as to complete the dehydration of the clothes, and therefore, the dehydration treatment in the intermittent stage is particularly critical.
In the prior art, the dehydration method of the intermediate dehydration stage is commonly used, in which the rotation duration and the stop duration of a fixed period are set, and the period is repeatedly executed until the intermediate dehydration stage is finished,
however, this method has some disadvantages, such as that in the intermittent dewatering stage of the washing machine with large capacity and constant frequency, the water is easily stored in the gap between the inner and outer barrels during dewatering at full water level. Therefore, the current of the motor corresponding to the inner barrel is increased, the motor is protected from overheating, the rotating speed is stopped, the motor is restarted after the temperature is reduced, and the continuous dehydration is repeated in cycles and cannot be carried out continuously. The occurrence of this phenomenon may cause incomplete dehydration, high moisture content of the laundry, and high complaint rate of the user.
In view of the above problems, the inventive concept of the present application is as follows: in the prior art, the dewatering method of the washing machine in the intermittent dewatering stage does not distinguish the water level of the inner barrel, and the motor is controlled to rotate only according to the preset rotating time length and the preset stopping time length. Based on this, the inventor finds that the water storage in the gap between the inner barrel and the outer barrel can be reduced by acquiring the current water level of the inner barrel of the washing machine in real time and then enabling the motor to execute different strategies of rotating time and stopping time at different water levels.
For example, the dewatering method of the washing machine provided by the embodiment of the present application can be applied to an application scenario diagram shown in fig. 1. Fig. 1 is a schematic view of an application scenario of a dewatering method of a washing machine according to an embodiment of the present application, so as to solve the above technical problem. As shown in fig. 1, the application scenario may include: a washing machine 11 and a server 12.
For example, in the application scenario shown in fig. 1, the washing machine 11 obtains the current water level of the inner tub of the washing machine 11, obtains the mapping relationship between the water level range and the water level provided by the server 12, determines the water level to which the current water level belongs according to the current water level and the mapping relationship, and then operates the motor and the drain pump of the washing machine 11 according to the rotation-stop duration of the motor and the opening-closing duration of the drain pump corresponding to the water level.
Alternatively, the mapping relationship between the water level range and the water level may be pre-configured by the washing machine 11 and stored in the configuration parameters of the washing machine 11.
Alternatively, the server 12 may be a device providing corresponding functions for a service platform corresponding to the washing machine 11, and the mapping relationship between the water level range and the water level may also be preset in the server 12.
The execution main body of the embodiment of the present application may be the washing machine 11, or may be a control device having a related control device for controlling the washing machine to perform the dehydration, that is, the control device can execute the dehydration method of the washing machine 11 provided in the embodiment of the present application.
The technical solution of the present application will be described in detail below with reference to specific examples.
It should be noted that the following several specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a dewatering method of a washing machine according to an embodiment of the present disclosure. As shown in fig. 2, the dehydration method of the washing machine may include the steps of:
and step 21, acquiring the current water level of the inner barrel of the washing machine when the washing machine carries out dehydration.
In this embodiment, the dewatering method of the washing machine will be described in detail by taking the execution body as an example of the washing machine.
In this step, the washing machine is used for dewatering, and when the washing machine is in a dewatering stage, in order to reduce the water level in the inner drum, the water in the clothes is thrown to the gap between the inner drum and the outer drum under the action of eccentricity because the motor drives the inner drum to rotate in the dewatering process, and at the moment, the current water level of the inner drum needs to be obtained.
Alternatively, the water level may be obtained by sensor measurements, e.g. by measuring the weight of the inner tub (water and laundry) by a pressure sensor, by comparison with the weight of the inner tub when fully loaded, etc.; the water level may be obtained according to the amount of water used when the washing machine starts a washing mode, for example, the user selects the amount of water to be supplied 24L, which is compared with the volume of the inner tub when the inner tub is fully loaded.
And step 22, determining a target water level grade corresponding to the water level according to the mapping relation between the water level range and the water level grade.
In this step, after the current water level is obtained, the motor and the drain pump need to be controlled to be in different operating states according to the height of the water level, and at this time, the target water level corresponding to the current water level is obtained according to the preset mapping relationship between the water level range and the water level.
In one possible implementation, taking the height of the inner tub of the washing machine as 850mm as an example, the mapping relationship between the water level range and the water level may be: 0mm-250mm is the low water level; 250mm (not including 250 mm) -500mm is the middle water level; 500 (not including 500 mm) -850mm is the high water level. That is, the water level levels include: low water level, medium water level and high water level.
In another possible implementation, the water level may also include: low water level, middle and low water level, middle and high water level, the principle is similar.
Optionally, the mapping relationship between the water level range and the water level grade is obtained from a service platform corresponding to the washing machine.
Specifically, the mapping relationship may be issued by a technician in a service platform corresponding to the washing machine, and obtained from the service platform corresponding to the washing machine when the washing machine is dehydrated.
Optionally, the mapping relationship between the water level range and the water level grade is obtained from the configuration parameters of the washing machine.
Specifically, the mapping relationship may be written in the configuration parameters of the washing machine at the time of factory shipment, and obtained from the configuration parameters of the washing machine when the washing machine is dehydrated.
And 23, determining the rotation and stop time of the motor and the opening and closing time of the drainage pump according to the target water level grade.
The rotation and stop duration of the motor comprises rotation duration and stop duration of the motor in a rotation and stop period, and the opening and closing duration of the drainage pump comprises opening duration and closing duration of the drainage pump in an opening and closing period.
In this step, in each water level class, a corresponding rotation/stop time period of the motor and an opening/closing time period of the drain pump are configured.
In a possible implementation, when the water level levels include a low water level, a middle water level and a high water level, taking the low water level as an example, the motor rotates 15S, stops 6S, and the drain pump closes 2S and opens 20S; taking a middle water level as an example, rotating the motor for 10S, stopping the rotation for 5S, closing the drainage pump for 2S and opening the drainage pump for 15S; taking high water level as an example, the motor rotates 5S and stops 4S, and the drainage pump is closed 2S and opened 10S.
It should be understood that: the above-mentioned number of seconds is only an example, and the following conditions should be satisfied for the rotation/stop time period of the motor and the opening/closing time period of the drain pump between the respective stages:
optionally, the rotation-stop ratio of the motor at the high water level is smaller than that of the motor at the medium water level, and the rotation-stop ratio of the motor at the medium water level is smaller than that of the motor at the low water level; the opening/closing ratio of the drain pump at the high water level is smaller than that of the drain pump at the medium water level, and the opening/closing ratio of the drain pump at the medium water level is smaller than that of the drain pump at the low water level. The rotation-stop ratio is the ratio of the rotation time length to the stop time length, and the opening-closing ratio is the ratio of the opening time length to the closing time length.
Namely: the rotation-stop ratio of the motor with high water level is as follows: 5S/4s =1.25; the rotation-stop ratio of the motor at the middle water level is as follows: 10S/5s =2; the rotation-stop ratio of the motor with low water level is as follows: 15S/6s =2.5; therefore, the following steps are carried out: 1.25 is less than 2,2 is less than 2.5.
The same principle is that: the opening/closing ratio of the high-water-level drainage pump is as follows: 10S/2s =5; the opening-closing ratio of the drainage pump at the middle water level is as follows: 15S/2s =7.5; the opening/closing ratio of the drain pump at the low water level is: 20S/2s =10; therefore, the following steps are carried out: 5 is less than 7.5,7.5 is less than 10.
Optionally, the time length of the motor stopping and the time length of the opening and closing of the drainage pump corresponding to each water level grade configured by the service platform are received and stored.
In a possible implementation, the rotation and stop time length of the motor and the opening and closing time length of the drainage pump corresponding to each water level grade configured by the service platform are received and stored in a local cache of the washing machine, when the current water level is determined to be at a low water level, the rotation and stop time length of the motor corresponding to the low water level is 15S for rotation and 6S for stopping, and the opening and closing time length of the drainage pump is 2S for closing and 20S for opening.
Optionally, if the rotation/stop time length of the motor and the opening/closing time length of the drain pump corresponding to each water level grade are in the configuration parameters of the washing machine, the rotation/stop time length and the opening/closing time length can be directly obtained from the configuration parameters.
And 24, controlling the operation of the motor and the drainage pump according to the rotation and stop time of the motor and the opening and closing time of the drainage pump.
In this step, the rotation duration and the stop duration of the motor in a rotation-stop period and the opening duration and the closing duration of the drainage pump in an opening-closing period are obtained, so that the motor and the drainage pump periodically operate according to the rotation-stop duration and the opening-closing duration respectively.
In a possible implementation, when the current water level of the inner barrel of the washing machine is a low water level, the rotation and stop time length (rotation 15S and stop 6S) of the motor and the opening and closing time length (closing 2S and opening 20S) of the drainage pump are acquired, the motor is periodically controlled to rotate 15S and stop 6S, and meanwhile, the drainage is controlled to close 2S and open 20S until the end of the intermittence stage.
In another possible implementation, when the current water level of the inner drum of the washing machine is the middle water level, the rotation and stop time length (rotation 10S and stop 5S) of the motor and the opening and closing time length (closing 2S and opening 15S) of the drainage pump are acquired, the motor is periodically controlled to rotate 10S and stop 5S, meanwhile, the drainage pump is controlled to close 2S and open 15S, the water level is continuously updated along with the operation of the motor and the drainage pump, and when the current water level is the low water level, the processing process when the water level is the low water level is repeated.
In another possible implementation, when the current water level of the inner tub of the washing machine is a high water level, acquiring the rotation stop time (rotation 5S, stop 4S) of the motor and the opening and closing time (closing 2S, opening 10S) of the drainage pump, periodically controlling the motor to rotate 5S and stop 4S, and at the same time, controlling the drainage pump to close 2S and open 10S, continuously updating the water level along with the operation of the motor and the drainage pump, and when the current water level is a middle water level, repeating the treatment process when the water level is the middle water level; when the current water level is the low water level, the above-mentioned processing procedure when the water level is the low water level is repeated.
After this step, the washing machine enters a continuous dewatering stage, thereby completing the whole process of dewatering the laundry.
According to the dewatering method of the washing machine, when the washing machine is dewatered, the current water level of the inner barrel of the washing machine is obtained, the target water level grade corresponding to the water level is determined according to the mapping relation between the water level range and the water level grade, then the rotating and stopping time length of the motor and the opening and closing time length of the drainage pump are determined according to the target water level grade, the rotating and stopping time length of the motor comprises the rotating time length and the stopping time length of the motor in a rotating and stopping period, the opening and closing time length of the drainage pump comprises the opening and closing time length of the drainage pump in an opening and closing period, and finally the motor and the drainage pump are controlled to operate according to the rotating and stopping time length of the motor and the opening and closing time length of the drainage pump. According to the technical scheme, starting from the water level grades of different water levels, the rotation and stop time of different motors and the opening and closing time of the drainage pump are configured, the condition that water is stored in the gap between the inner barrel and the outer barrel of the washing machine is reduced, and the dewatering efficiency of the washing machine is improved.
On the basis of the above embodiments, a dewatering method of a washing machine at a high water level is illustrated, and fig. 3 is a schematic flow chart of a second embodiment of the dewatering method of the washing machine provided in the embodiment of the present application. As shown in fig. 3, the dehydration method of the washing machine includes the steps of:
step 1, acquiring the water level of an inner barrel of the current washing machine;
step 2, determining that the target water level grade corresponding to the water level is a high water level according to the mapping relation between the water level range and the water level grade;
step 3, controlling the operation of the motor and the drainage pump according to the rotation and stop time length of the motor corresponding to the high water level and the opening and closing time length of the drainage pump;
in the step, the step 4 is executed after the motor and the drainage pump are controlled to operate for a first preset time according to the rotation and stop time of the motor corresponding to the high water level and the opening and closing time of the drainage pump.
