Rather, the invention is to cover all modifications, modifications and equivalents within the spirit and scope of the appended claims.

An automatic control method of a washing machine according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 2, the automatic control method of the washing machine in the embodiment of the present invention includes the following steps:

5201, receiving an instruction input by a user through a button, so that the washing machine is performed in a weighing mode, wherein the weighing mode is associated with the motor. In one embodiment of the invention, the button can be a start button. In another embodiment of the invention, the button can also be a power button. Wherein, when the button is a start button, the washing machine further comprises a power button, wherein the power button is different from the start button. And, the weighing mode can be fuzzy weighing. The automatic control method of the washing machine proposed in one embodiment of the present invention will be described below by using the button as a start button.

In a specific embodiment of the present invention, the user inputs the command through the start button of the washing machine, and after receiving the command information, the motor of the washing machine is controlled to rotate in the weighing mode, and the motor of the washing machine controls the rotation of the drum. In an embodiment of the present invention, the weighing mode may control the cylinder to rotate in a preset rotation speed and a rotation direction sequence, wherein the sequence may be understood as controlling the cylinder to rotate once according to a preset direction such as a forward rotation direction or a reverse rotation direction. Or multiple times, for example, according to the slower rotation speed, the control cylinder is rotated once in the forward rotation direction, and then the cylinder is rotated once in the reverse direction to stop, and then rotated again to stop. In the process of controlling the cylinder stop of the washing machine, the motor of the washing machine generates a counter electromotive force, thereby obtaining the weight of the laundry, thereby proceeding to step S202.

5202, obtaining the weight of the laundry in the cylinder according to the counter electromotive force of the rotating motor.

When the drum of the washing machine is controlled to perform the turning-off process in the weighing mode in step S201, the motor of the washing machine generates an anti-electromotive force, and the weight of the laundry in the drum is obtained according to the counter electromotive force of the motor. For example, when the load is large, that is, when the laundry is large, the back electromotive force of the motor is short, for example, 0.5 second, and the number of pulses generated is, for example, three, which may be based on the duration of the counter electromotive force generated when the washing motor is stopped and the number of pulses generated. Obtaining the weight of the laundry in the cylinder can be understood as the duration of the back electromotive force of the motor and the number of generated pulses corresponding to the laundry in the cylinder. After the weight of the laundry in the washing machine drum is determined, the process proceeds to step S203.

5203. Determine a corresponding water level and a corresponding laundry mode according to the weight of the laundry in the tube, and control the washing machine to perform a washing operation.

The corresponding water level is determined according to the weight of the laundry obtained in step S202, and the weight of the different clothes may correspond to different water levels. For example, if the weight of the laundry obtained in step S202 is in the range of 0-1 kilogram, it may be set as The low water level, when the weight of the clothes is within the range of 1-2 kg, can be set to the mid-range water level, and the weight of the clothes can be set to the high-grade water level when the weight is more than 2 kg. A corresponding laundry mode is obtained by the weight of the obtained laundry, wherein the laundry mode may include laundry time, number of rinsing, dehydration time, and laundry tempo corresponding to the weight of the laundry. As shown in Table 1, for example, the weight of the laundry is 0-1 kg (KG), the corresponding water level is 1st gear, that is, the low water level, the washing time is 9 minutes, the rinsing frequency is 1 time, the dehydration time is 3 (minutes), and the laundry beat is Stop, forward, stop, reverse, the number of times is 14, 9, 14, 9, each time is 0.1 seconds. There are different water level and laundry modes corresponding to different clothes weights.

Table 1

It can be seen that the more clothes, the greater the weight of the clothes, for example, more than 2 kilograms, the stronger the laundry beat, the longer the washing time, the more the number of rinsing times, the longer the dehydration time, the longer the washing time, and the difference in the laundry time according to the length of the laundry time. .

In summary, after receiving the instruction to start the button input, the weight of the laundry can be automatically weighed, and the appropriate water level is selected according to the weight of the laundry, and the laundry mode is determined according to the weight of the laundry and the water level.

5301, the washing machine is powered on.

5302, the user triggers the start button.

If the number of triggering start button is 1, then the process goes to step S303. If the number of times the trigger start button is 2, the process goes to step S308, that is, the single-off process is directly performed, and the single-off mode is entered; if the start button time is triggered, the preset time is, for example, 3 seconds. Then, the process proceeds to step S304.

5303, obtain the weight of the laundry, and allocate the washing parameters according to the weight of the laundry.

That is, the corresponding water level is determined according to the weight of the laundry, and the laundry mode, that is, the laundry time, the number of rinsing times, the dehydration time, and the laundry tempo are determined according to the water level. After all the parameters are assigned, the process proceeds to step S305.

5304, Determine the water level to the maximum water level.

If the start button time is set to a preset time, for example, 3 seconds, it is determined that the water level is the maximum water level, and after the water level is determined, the process proceeds to step S305.
