The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A control method, system and washing machine of a top-loading washing machine according to embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of a top-loading washing machine according to an embodiment of the present invention.
First, referring to fig. 2, the washing machine related to the method includes, for example, a box, an outer cylinder and an inner cylinder, and further includes a sensing component disposed on the outer cylinder, and a calibration component disposed on two preset calibration points of a coaxial belt of the inner cylinder, wherein the two preset calibration points and an axis of the inner cylinder are not on a straight line. In the operation process of the inner cylinder, the sensing component fixed on the outer cylinder is relatively static, the calibration component arranged on the coaxial belt of the inner cylinder follows the station of the belt, and when the calibration component passes through the sensing component, the sensing component records a sensing signal.
In a specific example, 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 belt, which has the advantages of low cost and easy installation.
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 specific structures and types of the sensing component and the calibration component are not limited to those described in the above examples, and are not repeated here to reduce redundancy.
Further, as shown in fig. 2, an angle θ formed by a connecting line between two preset calibration points (or a calibration component located at the calibration points, such as magnetic steel) and the axis of the inner cylinder is smaller than or equal to a difference between the opening angle α of the outer cylinder and the preset angle. The preset angle is, for example, one third of the inner cylinder opening angle β. Specifically, first, in order to ensure the accuracy of positioning the inner cylinder, the angle θ between the two preset calibration points and the axis needs to be smaller than the range of the outer cylinder opening angle α + the inner cylinder opening angle β, and further, in order to improve the positioning accuracy, it needs to ensure that at least 2/3 of the inner cylinder opening angle β is exposed, so that the angle θ between the two preset calibration points and the axis of the inner cylinder is smaller than or equal to the difference between the outer cylinder opening angle α and the 1/3 of the inner cylinder opening angle β, that is:
therefore, when the calibration assembly is within the range of the angle theta, the door cover of the inner cylinder faces upwards and is in a reasonable position.
The method provided by the embodiment of the invention is suitable for the beginning or the end of a washing program, so that the inner cylinder door is upward by positioning and controlling the position of the inner cylinder, and the clothes are convenient to put and take. Specifically, as shown in fig. 1, the control method of the top-loading washing machine includes the steps of:
step S1: controlling the rotation of the inner drum of the washing machine.
Specifically, for example, when the washing program is started or ended, such as a washing machine start button is triggered, or after the dehydration is completed, the washing machine drum is controlled to start rotating.
Step S2: when the sensing assembly of the washing machine senses the two sensing signals, it is determined whether a time interval T1 between the two sensing signals is greater than or equal to a first preset time T1 and the inner drum is controlled to stop rotating. Namely, whether the magnetic steel at the two calibration points passes through the magnetic sensor is judged, if so, the magnetic sensor receives two sensing signals, then, whether the time interval T1 between the two sensing signals is greater than or equal to a first preset time T1 is judged, and the inner cylinder is controlled to stop rotating, namely, the rotation is stopped.
Step S3: and if the time interval T1 is less than the first preset time T1, controlling the inner barrel to rotate reversely and then stop rotating. In other words, when it is determined that the time interval T1 between the sensed two sensing signals is less than T1, the drum of the washing machine is controlled to rotate in a reverse direction and then to be stopped. Note that, here, the reverse rotation is with respect to the inner cylinder rotation direction in step S1, that is, in step S3, the inner cylinder is controlled to rotate in the direction opposite to the inner cylinder rotation direction in step S1 and then to stop rotating.
Step S4: it is determined whether the number of sensing signals sensed by the sensing elements is one when step S3 is performed, and if not, it returns to step S1. In other words, it is determined whether the number of sensing signals sensed by the sensing assembly is 1 during the reverse rotation of the inner tub, and if not, the process returns to step S1, i.e., the inner tub is controlled to rotate.
In one embodiment of the present invention, in step S1, the specific manner of controlling the rotation of the inner drum of the washing machine is, for example: controlling the inner drum of the washing machine to rotate at a first preset rotating speed.
Further, in an embodiment of the present invention, in step S2, the manner of controlling the inner barrel to stall is: controlling the delay stalling of the inner cylinder. More specifically, the method for controlling the delay stalling of the inner cylinder specifically comprises the following steps: if the time interval T1 between the two sensed signals is greater than or equal to the first preset time T1, controlling the inner cylinder to stop rotating after delaying the third preset time T3; and if the time interval T1 is less than the first preset time T1, controlling the inner barrel to stop rotating after delaying the fourth preset time T4.
In an embodiment of the present invention, in step S3, the specific way of controlling the inner cylinder to stop rotating after rotating in the reverse direction is, for example: and after the inner cylinder is controlled to rotate reversely at the second preset rotating speed for the second preset time T2, the inner cylinder is controlled to stop rotating.
The second preset time T2 is set according to the time interval T1, for example. For example, the specific setting manner of the second preset time T2 is as follows: segmenting a time interval T1, and when T1 is less than or equal to 400ms, T2 is 200 ms; when the time is 400ms < T1 < 700ms, T2 is 400 ms; when T1 is 700ms or more, T2 is 500 ms. Furthermore, the first preset rotating speed and the second preset rotating speed can be selected according to actual requirements, such as the distance between two preset calibration points. Generally, the first preset rotating speed and the second preset rotating speed are selected to be smaller speeds, such as less than or equal to 30rpm, and similarly, the first preset time and the second preset time are both shorter times, so that the inner cylinder is ensured to run at a smaller speed in a short time and advance for a smaller angle, the calibration assembly can be stopped in a reasonable range (such as an angle theta range), the opening of the inner cylinder is enabled to face upwards, and the accuracy of the position positioning of the inner cylinder is improved.
For example, the following steps are carried out: that is, the inner cylinder is controlled to rotate at a smaller rotation speed (a first preset rotation speed), and in the process, whether the sensing assembly detects two sensing signals is judged, i.e. whether both magnetic steels pass through the magnetic sensor, if both magnetic steels pass through the magnetic sensor, i.e., two sensing signals are detected, it is determined whether the time interval T1 between the two sensing signals is greater than or equal to the first preset time T1, if yes, controlling the inner cylinder to stall after delaying for a third preset time T3, if the time interval T1 is less than the first preset time T1, controlling the inner cylinder to stall after delaying for a fourth preset time T4, then reversely rotates at a lower rotating speed (second preset rotating speed) for a short time (second preset time T2), the inner cylinder is controlled to stop rotating, at this time, the two magnetic steels are in a reasonable range (such as an angle theta range), the opening of the inner barrel is upward, and a user can conveniently place and take clothes. Further, it is determined whether the number of sensing signals sensed by the sensing assembly during the reverse rotation of the inner cylinder is one, and if not, the inner cylinder is controlled to rotate again, i.e., the process returns to step S1.
Further, in an embodiment of the present invention, before step S1, the method further includes: and a shaking process is carried out so as to shake the clothes in the inner barrel. The reason is that after the washing machine finishes dewatering, the clothes can cling to the wall of the inner drum, so that the clothes need to be shaken off first, and the clothes are scattered in the drum under the action of gravity. Specifically, the shaking-out process includes the steps of:
step 1: and after the inner cylinder is controlled to rotate forwards at the third preset rotating speed for the fifth preset time, the inner cylinder is controlled to rotate backwards at the fourth preset rotating speed for the sixth preset time.
Step 2: and (5) repeatedly executing the step (1) until the preset times.
Specifically, the third and fourth preset rotation speeds, the fifth and sixth preset times and the preset times can be selected according to actual requirements, for example, according to the material, weight and the like of the laundry, as long as it is ensured that the laundry in the inner drum can be shaken out after the step 2 is executed for the preset times.
According to the control method of the top-opening washing machine, in the process of controlling the rotation of the inner cylinder, the position of the inner cylinder is judged according to the number of the sensing signals recorded by the sensing assembly and the time interval between the sensing signals, the position of the inner cylinder of the washing machine can be accurately positioned, and the inner cylinder is controlled according to the position of the inner cylinder, so that the position of the door cover of the inner cylinder is upward when the washing machine is stopped, a user can conveniently take clothes, and the method is easy to implement and low in required cost.
The invention further provides a control system of the top-loading washing machine.
Fig. 3 is a block diagram of a control system of a top-loading washing machine according to an embodiment of the present invention.
First, referring to fig. 2, the washing machine related to the system includes, for example, a box, an outer cylinder and an inner cylinder, and further includes a sensing component disposed on the outer cylinder, and a calibration component disposed on two preset calibration points of a coaxial belt of the inner cylinder, wherein the two preset calibration points and an axis of the inner cylinder are not in a straight line. In the operation process of the inner cylinder, the sensing component fixed on the outer cylinder is relatively static, the calibration component arranged on the coaxial belt of the inner cylinder follows the station of the belt, and when the calibration component passes through the sensing component, the sensing component records a sensing signal.
In a specific example, 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 belt, which has the advantages of low cost and easy installation.
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 specific structures and types of the sensing component and the calibration component are not limited to those described in the above examples, and are not repeated here to reduce redundancy.
Further, as shown in fig. 2, an angle θ formed by a connecting line between two preset calibration points (or a calibration component located at the calibration points, such as magnetic steel) and the axis of the inner cylinder is smaller than or equal to a difference between the opening angle α of the outer cylinder and the preset angle. The preset angle is, for example, one third of the inner cylinder opening angle β. Specifically, first, in order to ensure the accuracy of positioning the inner cylinder, the angle θ between the two preset calibration points and the axis needs to be smaller than the range of the outer cylinder opening angle α + the inner cylinder opening angle β, and further, in order to improve the positioning accuracy, it needs to ensure that at least 2/3 of the inner cylinder opening angle β is exposed, so that the angle θ between the two preset calibration points and the axis of the inner cylinder is smaller than or equal to the difference between the outer cylinder opening angle α and the 1/3 of the inner cylinder opening angle β, that is:
therefore, when the calibration assembly is within the range of the angle theta, the door cover of the inner cylinder faces upwards and is in a reasonable position.
The control system of the top-opening washing machine provided by the embodiment of the invention is suitable for the beginning or the end of a washing program, so that the inner drum door is upward by positioning and controlling the position of the inner drum, and the clothes are convenient to put and take.

Wherein, the second preset time T2 is set according to the time interval T1. For example, the specific setting manner of the second preset time T2 is as follows: segmenting a time interval T1, and when T1 is less than or equal to 400ms, T2 is 200 ms; when the time is 400ms < T1 < 700ms, T2 is 400 ms; when T1 is 700ms or more, T2 is 500 ms. Furthermore, the first preset rotating speed and the second preset rotating speed can be selected according to actual requirements, such as the distance between two preset calibration points. Generally, the first preset rotating speed and the second preset rotating speed are selected to be smaller speeds, such as less than or equal to 30rpm, and similarly, the first preset time and the second preset time are both shorter times, so that the inner cylinder is ensured to run at a smaller speed in a short time and advance for a smaller angle, the calibration assembly can be stopped in a reasonable range (such as an angle theta range), the opening of the inner cylinder is enabled to face upwards, and the accuracy of the position positioning of the inner cylinder is improved.
