According to the control method of the top-opening washing machine, the inner barrel of the washing machine is controlled to rotate, then the size relation between the time interval of the two sensing signals sensed by the sensing assembly of the washing machine and the set interval duration is compared, and then the inner barrel is controlled to continue to rotate for the corresponding duration according to the size relation and then stops rotating.

And, need not to adopt mechanical system to keep interior bucket opening direction up, can reduce the complexity of hardware to reduction in production cost does benefit to the marketing of top-opening washing machine.
A control method and apparatus of a top-loading washing machine and a top-loading washing machine according to embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a control method of a top-loading washing machine according to an embodiment of the present disclosure.
The embodiment of the present application exemplifies that the control method of the top-loading washing machine is configured in the control device of the top-loading washing machine, and the control device of the top-loading washing machine can be configured in the top-loading washing machine, so that the top-loading washing machine can execute the control function.
The control method of the top-opening washing machine in the embodiment of the application can be suitable for the beginning or the end of a washing program, so that the inner barrel can be positioned and controlled to enable the door of the inner barrel to face upwards, and clothes can be conveniently put in and taken out.
As an example, referring to fig. 2, fig. 2 is a schematic structural diagram of a top-loading washing machine according to a second embodiment of the present application. Among them, the top-loading type washing machine may include, for example: the box body, the outer barrel and the inner barrel further comprise a sensing assembly arranged on the outer barrel and a calibration assembly arranged on two preset calibration points on the inner barrel coaxial driving wheel, wherein the two preset calibration points and the axis of the inner barrel are not on the same straight line. In the rotating process of the inner barrel, the sensing assembly fixed on the outer barrel is relatively static, the two calibration assemblies arranged on the coaxial driving wheel of the inner barrel rotate along with the driving wheel, and when the calibration assemblies pass through the sensing assembly, the sensing assembly generates a sensing signal.
In some examples, the sensing component may be, for example, a magnetic sensor, and correspondingly, the calibration component may be, for example, a magnetic element, such as a magnetic steel. More specifically, as shown in fig. 2, the calibration component is, for example, magnetic steel disposed on two preset calibration points on the driving wheel, and has the advantages of low cost and easy installation. In some embodiments of the present application, the sensing component may be a reed switch or a hall device.
In other examples, the sensing component may also be a photosensitive element, such as a photodiode, and accordingly, the calibration component may be composed of a light emitting element and a light shielding member, such as a light emitting diode and a light shielding member, and as such, has the advantages of low cost and easy installation.
It should be noted that the specific structures and types of the sensing component and the calibration component are not limited to the above examples, and are not repeated here to reduce redundancy.
Further, referring to fig. 2, an angle θ formed by two predetermined calibration points (or calibration components located at the calibration points, such as magnetic steel) and a connecting line of the axis of the inner barrel is smaller than or equal to a difference between an outer barrel opening angle α and a predetermined angle, wherein the predetermined angle is, for example, one third of an inner barrel opening angle β, specifically, first, in order to ensure the accuracy of positioning the inner barrel, the angle θ formed by the two predetermined calibration points and the connecting line of the axis needs to be smaller than a range of the outer barrel opening angle α + the inner barrel opening angle β, and further, in order to improve the positioning accuracy, at least 2/3 of the inner barrel opening angle β needs to be exposed, therefore, the angle θ formed by the two predetermined calibration points and the connecting line of the axis of the inner barrel needs to be smaller than or equal to a difference between an outer barrel opening angle α and an:
therefore, when the calibration assembly is within the range of the angle theta, the door cover of the inner barrel faces upwards and is in a reasonable position.
As shown in fig. 1, the control method of the top-loading type washing machine includes the steps of:
In the embodiment of the application, when the washing program starts or ends, the inner tub of the washing machine can be controlled to rotate in order to position the opening position or the opening direction of the inner tub.
In the embodiment of the present application, the set interval duration is preset, for example, the set interval duration may be preset for a built-in program of the top-loading washing machine, or the set interval duration may be set by a user, which is not limited thereto. It is understood that the set interval period is related to the rotation speed of the inner tub, and the set interval period is smaller as the rotation speed of the inner tub is higher, and is larger as the rotation speed of the inner tub is lower.
In the embodiment of the application, in the rotating process of the inner barrel, the sensing assembly fixed on the outer barrel is relatively static, the calibration assemblies of two preset calibration points arranged on the coaxial driving wheel of the inner barrel rotate along with the driving wheel, and when the calibration assemblies pass through the sensing assembly, the sensing assembly generates a sensing signal. For example, the calibration components for marking two preset calibration points are M1 and M2, respectively, the sensing component can generate a corresponding sensing signal when M1 passes by the sensing component, and the sensing component can also generate a corresponding sensing signal when M2 passes by the sensing component, so that the time interval of the two sensing signals can be determined according to the generation time of the two sensing signals. Specifically, the time interval may be obtained by subtracting the generation times of the two sensing signals, and then the time interval may be compared with the set interval duration to obtain the magnitude relationship between the time interval and the set interval duration.
It can be understood that when the relative positions of the sensing assembly and the two calibration assemblies are different, the time interval is different, for example, referring to fig. 3, the angle formed by the connecting line of the two preset calibration points (or the calibration assemblies M1 and M2 located at the calibration points) and the axis of the inner tub is θ, and when the sensing assembly is located on the arc of the outer tub corresponding to the angle θ at the beginning or end of the washing process, i.e. when the sensing assembly is located in the middle of the two calibration assemblies, when the inner tub rotates in the clockwise direction, the sensing assembly passes through the calibration assembly M2 first and then the calibration assembly M1, the time interval 1 of the two sensing signals can be determined according to the angle (2 pi- θ) and the rotation speed of the inner tub.
For another example, referring to fig. 4, when the sensing assembly is located on the arc of the outer tub corresponding to the angle (2 pi-theta) at the beginning or end of the washing process, i.e. when the two calibration assemblies are located at one side of the sensing assembly, the sensing assembly passes through the calibration assembly M1 first and then passes through the calibration assembly M2, and the time interval 2 between the two sensing signals can be determined according to the angle theta and the rotation speed of the inner tub. Since (2 π - θ) is greater than θ, it can be seen that time interval 1 is greater than time interval 2.
It should be noted that fig. 3 and 4 only illustrate the inner tub rotating in a clockwise direction, and in practical applications, if the inner tub rotates in a counterclockwise direction, at the beginning or the end of a washing program, if the sensing component is located in the middle of the two calibration components, the time interval 1 and the angle (2 pi-theta) of the two sensing signals can be obtained as well as related to the inner tub rotation speed, and if the two calibration components are located at one side of the sensing component, the time interval 2 and the angle theta of the two sensing signals can be obtained as well as related to the inner tub rotation speed.
And 103, controlling the inner barrel to continue rotating for a corresponding time length according to the size relation and then stopping rotating.
As can be seen from fig. 2, when the sensing assembly is located between the two calibration assemblies, the opening direction of the inner barrel is right upward, that is, the opening of the inner barrel is located at the set position, and when the sensing assembly is not located between the two calibration assemblies, the opening of the inner barrel is not located at the set position. Specifically, it can be determined whether the sensing assembly is located between the two calibration assemblies or the two calibration assemblies are located at one side of the sensing assembly, so as to determine the opening direction of the inner barrel according to the relative position relationship between the sensing assembly and the calibration assemblies.
As a possible implementation manner, the set interval duration may be located between the time interval 1 and the time interval 2, that is, the time interval 2< the set interval duration < the time interval 1, so that after the time interval when the sensing component of the washing machine senses the two sensing signals is known, the time interval may be compared with the set interval duration, if the time interval is greater than the set interval duration, it indicates that the washing program starts or ends, the sensing position is located between the two calibration components, and if the time interval is less than the set interval duration, it indicates that the washing program starts or ends, the two calibration components are located at one side of the sensing component.
In the embodiment of the application, after the relationship between the time interval and the set time interval is determined, the opening direction of the inner barrel can be determined when the washing program starts or ends, and then the inner barrel can be controlled to continue to rotate for the corresponding time interval and then stop rotating, so that the opening direction of the inner barrel is adjusted to be upward, namely the opening of the inner barrel is located at the set position.
For example, referring to fig. 3, when the sensing assembly S passes through the calibration assembly M1, it may be determined that the time interval is greater than the set time interval, which indicates that the opening of the inner tub is located at the set position at the beginning or end of the washing process, but at this time, the sensing assembly S is located directly below the calibration assembly M1, and the opening of the inner tub is not directed upward, so that the inner tub may be controlled to continue to rotate such that the sensing assembly S is located between the two calibration assemblies, and the opening of the inner tub is directed upward, i.e., such that the opening of the inner tub is located at the set position. For example, the inner tub may continue to rotate for an angle less than θ, i.e., the inner tub may continue to rotate for a period less than time interval 2, or the inner tub may continue to rotate for a period between (2k π, 2k π + θ), i.e., the inner tub continues to rotate for a period between (k (time interval 1+ time interval 2), time interval 2+ k (time interval 1+ time interval 2)), such that the sensing assembly is located between the two calibration assemblies. Where k is a natural number including 0.
For another example, referring to fig. 4, when the sensing assembly S passes through the calibration assembly M2, it may be determined that the time interval is less than the set time interval, which indicates that the opening of the inner tub is not located at the set position at the beginning or end of the washing process, and that the opening of the inner tub is not upward when the sensing assembly S is located directly below the calibration assembly M2, so that the inner tub may be controlled to continue to rotate such that the sensing assembly S is located between the two calibration assemblies, and the opening of the inner tub is upward, i.e., the opening of the inner tub is located at the set position. For example, the inner barrel may continue to rotate by an angle greater than (2 π - θ) and less than 2 π, i.e., the inner barrel may continue to rotate for a period greater than time interval 1 and less than (time interval 1+ time interval 2), or the inner barrel may continue to rotate by an angle greater than (2k π + (2 π - θ)) and less than (2k π +2 π), i.e., the inner barrel may continue to rotate for a period between (k × (time interval 1+ time interval 2) + time interval 1, (k +1) (time interval 1+ time interval 2)), such that the sensing assembly is located between the two calibration assemblies. Where k is a natural number including 0.
In summary, in the present application, when the time interval is greater than the set time interval, the inner tub may continue to rotate for a period of time between (k × time interval 1+ time interval 2, time interval 2+ k × time interval 1+ time interval 2), and when the time interval is less than the set time interval, the inner tub may continue to rotate for a period of time between (k × time interval 1+ time interval 2) + time interval 1, (k +1) (time interval 1+ time interval 2)).
According to the control method of the top-opening washing machine, the inner barrel of the washing machine is controlled to rotate, then the size relation between the time interval of the two sensing signals sensed by the sensing assembly of the washing machine and the set interval duration is compared, and then the inner barrel is controlled to continue to rotate for the corresponding duration according to the size relation and then stops rotating. In this application, according to the sensing subassembly sensing to two sensing signal's time interval and the big or small relation between the length of setting for the interval, can confirm when the washing procedure begins or finishes, sensing subassembly and two calibration assembly's relative position relation, thereby confirm interior bucket opening position or interior bucket opening direction, and then according to big or small relation, the interior bucket of control continues to rotate and stops rotating after corresponding length of time, can realize adjusting interior bucket opening direction, make interior bucket opening direction up, even get interior bucket opening and be located the position of setting for, can compromise the efficiency of interior bucket opening location and the accuracy of location, and simultaneously, be convenient for the user to put the clothing into and get. And, need not to adopt mechanical system to keep interior bucket opening direction up, can reduce the complexity of hardware to reduction in production cost does benefit to the marketing of top-opening washing machine.
To clearly illustrate the above embodiment, the present embodiment provides another control method for a top-loading washing machine, and fig. 5 is a flowchart illustrating the control method for the top-loading washing machine according to the third embodiment of the present application.
As shown in fig. 5, the control method of the top-loading type washing machine may include the steps of:
It should be noted that, when the inner tub of the washing machine is controlled to rotate, if the rotation speed of the inner tub is fast, the time interval between the sensing components sensing the two sensing signals is small, and the set interval duration is also small. Because the time interval is compared with the set time interval due to factors such as shaking of the inner barrel, and the like, and a condition of misjudgment can occur, as a possible implementation manner of the embodiment of the application, in order to improve the accuracy of the calculation result of the time interval and reduce the probability of misjudgment, in the application, the inner barrel can be controlled to rotate at a lower rotation speed, for example, the inner barrel can be controlled to rotate at a rotation speed less than or equal to 35 Revolutions Per minute (rpm).
In step 202, a time interval between two sensing signals sensed by a sensing assembly of the washing machine is obtained.
The execution process of step 202 may refer to the execution process of step 102 in the above embodiments, which is not described herein again.
In step 203, it is determined whether the time interval is greater than the set interval duration, if so, step 204 is executed, and if not, step 205 is executed.
And step 204, controlling the inner barrel to continue rotating for a first time period and then stopping rotating.
In the embodiment of the present application, when the time interval is longer than the set interval duration, for example, referring to fig. 3, when the sensing component generates the second sensing signal, the sensing component is located directly below the calibration component M1, and the opening direction of the inner barrel is not upward, so that the inner barrel can be controlled to continue rotating for the first duration and then stop rotating, so that the sensing component is located between the two calibration components, and the opening direction of the inner barrel is upward, i.e. the opening of the inner barrel is located at the set position.
For example, the angle of continued rotation of the inner tub may be smaller than θ, i.e., the first duration of continued rotation of the inner tub may be smaller than time interval 2, or the angle of continued rotation of the inner tub may be located between (2k pi, 2k pi + θ), i.e., the first duration of continued rotation of the inner tub may be located between (k x (time interval 1+ time interval 2), time interval 2+ k x (time interval 1+ time interval 2)), such that the sensing assembly is located between the two calibration assemblies. Where k is a natural number including 0.
As an example, after the top-loading washing machine is used to spin off the laundry of different weights, the sensing assembly may be adjusted to the middle of the two calibration assemblies, and then the washing machine is tested using the laundry of different weights and different first time periods, with the test results shown in table 1. Wherein, table 1 shows the success rate of the inner tub opening being in the set position under different weights of laundry and different first time periods.
TABLE 1 success rates corresponding to the first time length values
Wherein ok represents 5 times of testing, the openings of the inner barrel are all positioned at the set position, no represents 5 times of testing, the openings of the inner barrel are not positioned at the set position, nok represents 5 times of testing, and the openings of the inner barrel are not all positioned at the set position.
As can be seen from table 1, when the weight of the laundry in the inner tub is within a reasonable range, that is, the load weight of the inner tub is within a reasonable range, in order to ensure that the opening of the inner tub is located at the set position, the value of the first time period may be about 5500 ms, for example, 5400 ms to 5600 ms.
In the embodiment of the present application, when the time interval is less than or equal to the set time interval, for example, referring to fig. 4, when the sensing component generates the second sensing signal, the sensing component is located right below the calibration component M2, and the opening direction of the inner barrel is not upward, so that the inner barrel can be controlled to continue rotating for the second time period and then stop rotating, so that the sensing component is located between the two calibration components, and the opening direction of the inner barrel is upward, i.e. the opening of the inner barrel is located at the set position.
For example, the angle of continued rotation of the inner barrel may be greater than (2 π - θ), and less than 2 π, i.e., the second duration of continued rotation of the inner barrel may be greater than time interval 1, and less than (time interval 1+ time interval 2), or the angle of continued rotation of the inner barrel may be greater than (2k π + (2 π - θ)), and less than (2k π +2 π), i.e., the second duration of continued rotation of the inner barrel may be located between (k (time interval 1+ time interval 2) + time interval 1, (k +1) × (time interval 1+ time interval 2)), thereby locating the sensing assembly in between the two calibration assemblies. Where k is a natural number including 0.
As an example, after the top-loading washing machine is used to spin off the laundry with different weights, the two calibration assemblies may be adjusted to one side of the sensing assembly, and then the washing machine is tested with the laundry with different weights and different second time periods, and the test results are shown in table 2. Wherein, table 2 shows the success rate of the inner tub opening being in the set position for different weights of laundry and different second time periods.
TABLE 1 success rates corresponding to the second duration values
As can be seen from table 2, when the weight of the laundry in the inner tub is within a reasonable range, that is, the load weight of the inner tub is within a reasonable range, in order to ensure that the opening of the inner tub is located at the set position, the value of the second time period may be about 5400 ms, for example, the value of the second time period may be about 5300 ms to 5500 ms.
As can be seen from the above steps, the first and second time periods are related to the rotation speed of the inner tub since the time interval 1 and the time interval 2 are related to the rotation speed of the inner tub, and as can be seen from tables 1 and 2, the first and second time periods are also different when the loads of the inner tub are different. In addition, the shaking degree of the inner tub may cause a deviation between the calculated first time period and the calculated second time period, and therefore, in the embodiment of the present application, the first time period is related to at least one of the rotation speed of the inner tub, the load weight of the inner tub, and the shaking degree of the inner tub, and similarly, the second time period is also related to at least one of the rotation speed of the inner tub, the load weight of the inner tub, and the shaking degree of the inner tub.
According to the control method of the top-opening washing machine, the inner drum is controlled to continue rotating for the duration corresponding to the size relation according to the size relation between the time interval and the set interval duration, and then the inner drum stops rotating. Therefore, the success rate that the inner barrel opening is positioned at the set position can be improved.
As a possible implementation manner, after the inner barrel is controlled to continue to rotate for the corresponding time length, the inner barrel can be further judged whether the opening of the inner barrel is located at the set position or not, if so, no processing can be performed, or a user can be prompted that the opening of the inner barrel is correct, if not, the time intervals of the two sensing signals can be detected again, and the relative position relationship between the sensing component and the calibration component is determined according to the size relationship between the time intervals and the set interval time length, so that the time length for the inner barrel to continue to rotate can be determined according to the relative position relationship, the corresponding time length for the inner barrel to continue to rotate is controlled, the opening of the inner barrel is ensured to be located at the set position, and the success rate for the. The above process is described in detail below with reference to fig. 6.
Fig. 6 is a flowchart illustrating a control method of a top-loading washing machine according to a fourth embodiment of the present application.
As shown in fig. 6, the control method of the top-loading type washing machine may include the steps of:
The execution process of step 301 may refer to the execution process of step 101 or step 201 in the above embodiments, which is not described herein again.

And step 303, controlling the inner barrel to continue rotating for a corresponding time length according to the size relation, and then stopping rotating.
The execution process of step 303 may refer to the execution process of step 103 in the above embodiment, or may execute the execution processes of steps 204 to 205 in the above embodiment, which is not described herein again.
The set times is determined according to the size relationship between the time interval and the set interval duration.
It can be understood that when the time interval is longer than the set interval, for example, referring to fig. 3, when the sensing component generates the second sensing signal, the sensing component is located right below the calibration component M1, the opening direction of the inner barrel is not upward, i.e. the opening of the inner barrel is not located at the set position, at this time, the inner barrel only needs to rotate by an angle less than θ continuously, so that the opening of the inner barrel can be located at the set position, at this time, the sensing component only passes through the calibration component 2 times, i.e. the set number is 2. Alternatively, the inner barrel may continue to rotate by an angle between (2k pi, 2k pi + θ), and at this time, the number of times that the sensing component passes through the calibration component is (2k +2), i.e., the set number of times may be (2k + 2).
When the time interval is less than or equal to the set interval, for example, referring to fig. 4, when the sensing component generates the second sensing signal, the sensing component is located right below the calibration component M2, the opening of the inner barrel is not directed upwards, i.e. the opening of the inner barrel is not located at the set position, at this time, the angle of continuous rotation of the inner barrel may be greater than (2 pi- θ) and less than 2 pi, so that the opening of the inner barrel is located at the set position, at this time, the sensing component passes through the calibration component 3 times, i.e. the set number of times is 3. Or, the angle of the inner barrel continuing to rotate may be greater than (2k pi + (2 pi-theta)) and smaller than (2k pi +2 pi), at this time, the number of times that the sensing component passes through the calibration component is (2k +3), that is, the set number of times may be (2k + 3).
And 305, determining that the opening of the inner barrel is at a set position.
In the embodiment of the application, when the times of sensing signals sensed by the sensing component meet the set times, the opening of the inner barrel is indicated to be at the set position.
Specifically, when the time interval is greater than the set interval duration, if the number of times that the sensing component senses the sensing signal matches (2k +2) times, it is determined that the inner tub opening is at the set position, and when the time interval is less than or equal to the set interval duration, if the number of times that the sensing component senses the sensing signal matches (2k +3) times, it is determined that the inner tub opening is at the set position.
And step 306, prompting a user that the opening of the inner barrel is correct.
In the embodiment of the application, when the opening of the inner barrel is located at the set position, the user can be prompted, so that the user can put and take clothes.
It should be noted that, the present application is only exemplified by performing step 306 after step 305, and in practical applications, step 306 may not be required to be performed.
And 307, determining that the opening of the inner barrel is not at the set position.
In this embodiment, when the number of times that the sensing component senses the sensing signal does not meet the set number of times, it indicates that the opening of the inner barrel is not located at the set position, at this time, step 302 and the subsequent steps may be performed, that is, the time interval between the two sensing signals is detected again, and the relative position relationship between the sensing component and the calibration component is determined according to the size relationship between the time interval and the time length of the set interval, so that the time length that the inner barrel continues to rotate may be determined according to the relative position relationship, and the corresponding time length that the inner barrel continues to rotate is controlled, so as to ensure that the opening of the inner.
