S1. Obtain the user's height;

S2. Selectively operate the lifting device to adjust the height of the washing tub according to the acquired height of the user.

In another aspect, the present invention also provides a pulsator washing machine, as shown in Figure 3, the pulsator washing machine includes a cabinet, a washing bucket, a lifting device, a height detection device, a distance detection device and a control device; wherein, washing The bucket is set in the box to accommodate the objects to be cleaned; the lifting device is set in the box to adjust the height of the washing bucket; the distance detection device is set on the front panel of the box to detect the distance between the user and the pulsator washing machine. The height detection device is arranged on the front panel of the box to detect the user's height, and the height detection device selectively performs the operation of detecting the user's height according to the detection result of the distance detection device; the control device is arranged on the table of the box On the panel, it controls the lifting device based on the detection result of the height detection device so as to adjust the height of the washing tub. Of course, the actual installation positions of the lifting device, the height detection device, the distance detection device and the control device are not limited to the above-mentioned installation positions, and those skilled in the art can flexibly set the lifting device, the height detection device, and the distance detection device in practical applications. And the actual installation position of the control device, as long as the lifting device, the height detection device, the distance detection device and the control device cooperate with each other, the lifting device can be selectively operated according to the height of the user so as to adjust the height of the washing tub.

Preferably, the lifting device is a telescopic rod, and the telescopic rod raises the washing bucket from the bottom of the cabinet in a telescopic manner, so as to reduce the distance between the user and the bottom of the washing bucket, so that the user can take out the clothes at the bottom of the washing bucket, and then Improved user experience. The telescoping rod can be extended in multiple stages to raise the washing tub to different heights. Certainly, the structure of the lifting device is not limited to the structure of the above example, and may also be a structure such as a lifting platform, a lift, a lift, a hydraulic rod, no matter what structure is adopted, as long as the height of the washing tub can be adjusted.

Preferably, the height detection device may be an infrared spectrum sensor, an ultrasonic distance measuring sensor, or a camera and other human body sensing distance measuring equipment.

Preferably, the distance detecting device may be an infrared spectrum sensor, an ultrasonic distance measuring sensor, or a camera and other human body sensing distance measuring equipment. It should be noted that the distance detection method should not limit the present invention.

When the control device receives the height signal detected by the height detection device, it compares the height with the preset height threshold, and according to the comparison result, the control device selectively controls the pulsator washing machine to adjust the height of the lifting device, so that the user can The clothes at the bottom of the washing bucket are taken out, thereby improving the user experience. Specifically, the control device may be the control device of the pulsator washing machine itself, or may be an additional control device or other mobile terminals, which will not be repeated here.

In a preferred embodiment, in the above step S2, the step of "selectively operating the lifting device to adjust the height of the washing tub according to the acquired height of the user" specifically includes:

S21. Comparing the height of the user with a preset height threshold;

S22. Selectively operate the lifting device to adjust the height of the washing tub according to the comparison result.

Preferably, the user's height is divided into multiple height levels. According to different height levels, the lifting device is reasonably operated to adjust the height of the washing tub, so that users of different heights can take out the clothes at the bottom of the washing tub, avoiding the user's height. It is too short to take out the clothes at the bottom of the washing bucket, which improves the user experience. Preferably, the height level is divided into four levels: very short, relatively short, somewhat short and high, wherein, the division of the height level can be flexibly adjusted and set according to the actual situation, for example, those skilled in the art under specific working conditions According to the experimental height level obtained from the experiment, or the empirical height level obtained from experience, as long as the height of the lifting device determined by the height level can meet the user's requirement for taking the clothes out of the washing tub.

Wherein, the preset height threshold includes a first preset height threshold, a second preset height threshold and a third preset height threshold.

Preferably, in the above step S22, the step of "selectively operating the lifting device to adjust the height of the washing tub according to the comparison result" specifically includes:

S221. If the height of the user is less than or equal to the first preset height threshold, do not adjust the height of the lifting device.

Specifically, if the height of the user is less than or equal to the first preset height threshold, it means that the user is very short, and the user can be considered as a child. Since children are not allowed to operate the pulsator washing machine, the height of the lifting device will not be adjusted. In order to prevent children from misoperating the pulsator washing machine, children are prevented from being injured due to misoperation of the pulsator washing machine, the use safety of the pulsator washing machine is improved, and the use experience of users is improved.

In the above process, through the setting of the first preset height threshold, a preliminary conclusion on whether to adjust the height of the lifting device can be given, so that the washing tub can adopt the optimal height mode under different circumstances, so that the lifting device can adjust according to the user's The height adjusts the height of the washing tub to meet the needs of the user to take out the clothes at the bottom of the washing tub, thereby improving the user experience. Wherein, the first preset height threshold may be the maximum height for judging that the user is a child, thereby preventing children from mishandling the pulsator washing machine and preventing children from being injured due to misuse of the pulsator washing machine. Of course, the above-mentioned first preset height threshold is not limited to the maximum height for judging that the user is a child, and can also be other heights, such as the experimental height obtained by those skilled in the art based on experiments under specific working conditions, or based on experience The empirical height only needs to meet the requirement of not adjusting the height of the lifting device determined by the first preset height threshold.

Preferably, in the above step S22, the step of "selectively operating the lifting device to adjust the height of the washing tub according to the comparison result" further includes:

S222. If the height of the user is greater than the first preset height threshold but smaller than the second preset height threshold, operate the lifting device to raise the washing tub to the first height.

Specifically, if the user's height is greater than the first preset height threshold but smaller than the second preset height threshold, it means that the user is short and it is difficult to take out the clothes at the bottom of the washing tub. In order to facilitate the user to take out the clothes at the bottom of the washing tub, then The lifting device is operated to raise the washing tub to the first height, thereby reducing the distance between the user and the bottom of the washing tub, enabling the user to take out the clothes at the bottom of the washing tub, thereby improving user experience.

Preferably, in the above step S222, the step of "operating the lifting device to raise the washing tub to the first height" specifically includes controlling the lifting device to stretch out two stages of length in a telescopic manner to raise the washing tub from the bottom of the cabinet to the first height. The first height enables the user to take out the clothes at the bottom of the washing tub. Certainly, the protruding length of the lifting device is not limited to two levels, those skilled in the art can flexibly set the protruding length of the lifting device in practical applications, as long as the user can take out the clothes at the bottom of the washing tub.

In the above process, through the setting of the second preset height threshold, a conclusion can be given whether to raise the washing tub to the first height, so that the washing tub can adopt the optimal height mode under different circumstances, so that the lifting The device can adjust the height of the washing tub according to the height of the user, so as to meet the needs of the user to take out the clothes at the bottom of the washing tub, thereby improving the user experience. Wherein, the setting of the second preset height threshold can be flexibly adjusted and set according to the actual situation, as long as the requirement of raising the washing tub to the first height determined by the second preset height threshold is met.

Preferably, in the above step S22, the step of "selectively operating the lifting device to adjust the height of the washing tub according to the comparison result" further includes:

S223. If the height of the user is greater than or equal to the second preset height threshold but smaller than the third preset height threshold, operate the lifting device to raise the washing tub to the second height;

S224. If the height of the user is greater than or equal to the third preset height threshold, do not adjust the height of the lifting device.

Specifically, if the height of the user is greater than or equal to the second preset height threshold but smaller than the third preset height threshold, it means that the user is a bit short, and it is difficult to take out the clothes at the bottom of the washing tub by virtue of its own height. The clothes at the bottom of the washing tub are taken out, and the lifting device is operated to raise the washing tub to a second height, thereby reducing the distance between the user and the bottom of the washing tub, so that the user can take out the clothes at the bottom of the washing tub; if the user If the height is greater than or equal to the third preset height threshold, it means that the user is taller, and the clothes at the bottom of the washing tub can be taken out by virtue of its own height without external force, and the height of the lifting device is not adjusted, thereby realizing the user's height. The purpose of selectively operating the lifting device to adjust the height of the washing tub is to meet the needs of users of different heights to take out the clothes at the bottom of the washing tub, thereby improving the user experience.

Preferably, in the above step S223, the step of "operating the lifting device to raise the washing tub to the second height" specifically includes: controlling the lifting device to stretch out a level of length in a telescopic manner to raise the washing tub from the bottom of the cabinet to the second height, enabling the user to remove laundry from the bottom of the tub. Of course, the protruding length of the lifting device is not limited to one level, and those skilled in the art can flexibly set the protruding length of the lifting device in practical applications, as long as the user can take out the clothes at the bottom of the washing tub.

Preferably, the second height is smaller than the first height.

In the above process, through the setting of the third preset height threshold, a conclusion can be given whether to raise the washing tub to the second height, so that the washing tub can adopt the optimal height mode under different circumstances, so that the lifting The device can adjust the height of the washing tub according to the height of the user, so as to meet the needs of the user to take out the clothes at the bottom of the washing tub, thereby improving the user experience. After repeated tests, observations, analyzes and comparisons by the inventor, it is determined that the third preset height threshold is the lowest height at which the user can take out the clothes at the bottom of the washing tub by virtue of his own height. In practical applications, the actual value of the third preset height threshold is not limited to the lowest height at which the user can take out the clothes at the bottom of the washing tub by virtue of his own height, and can be obtained by those skilled in the art based on experiments or experience.

In a preferred implementation manner, before the above step S1 of "obtaining the user's height", the control method further includes:

S01. Acquiring the distance between the user and the pulsator washing machine;

S02. Selectively perform an operation of obtaining the user's height according to the distance.

Further, in the above step S02, the step of "selectively performing the operation of obtaining the user's height according to the distance" specifically includes:

S021. Determine whether the distance is less than or equal to a preset distance threshold;

S022. If the distance is less than or equal to the preset distance threshold, perform the operation of acquiring the height of the user;

S023. If the distance is greater than the preset distance threshold, the operation of acquiring the height of the user is not performed.

Specifically, if the distance is less than or equal to the preset distance threshold, it means that the user is already within the range of the preset distance threshold, and it can be considered that the user wants to operate the pulsator washing machine, such as taking out the clothes at the bottom of the washing tub. To adjust the height of the washing tub, perform the operation of acquiring the user's height; if the distance is greater than the preset distance threshold, it can be considered that the user is outside the range of the preset distance threshold, and it is not intended to operate the pulsator washing machine, then do not perform the operation of acquiring the user's height The operation avoids the operation of obtaining the height of the user when the user does not intend to operate the pulsator washing machine, avoids the waste of energy, and improves the user experience.

In the above process, through the setting of the preset distance threshold, a conclusion can be given whether to perform the operation of obtaining the user's height, so that the pulsator washing machine can adopt the optimal operation mode of obtaining the user's height in different situations. Wherein, the preset distance threshold is the maximum distance within which the user can operate the pulsator washing machine. In practical applications, the actual value of the preset distance threshold is not limited to the maximum distance that the user can operate the pulsator washing machine. The setting of the preset distance threshold can be flexibly adjusted and set according to the actual situation, as long as the preset distance The threshold determines whether to perform the operation of obtaining the user's height.

Of course, steps S01 and S02 may also be performed while step S1 is being performed, and this change does not deviate from the principle and scope of the present invention.
