It should be noted that the present invention is directed to a washing machine and S0N in the present invention does not represent the sequence of the method for smoothing operation of the washing machine based on the pressure sensor, and the method for smoothing operation of the washing machine based on the pressure sensor according to the present invention is described in detail below.
Step S01, receiving pressure values collected by at least three pressure sensors; the pressure sensors are distributed at preset positions of the washing machine base, and pressure values borne by the preset positions are collected; .
It should be noted that before the washing machine operation system receives the pressure values collected by the at least three pressure sensors, the at least three pressure sensors are required to be arranged on the washing machine base based on the preset position, and all the pressure sensors are uniformly arranged on the washing machine base and support the washing machine base, so as to collect the pressure born by the preset position of the washing machine base and upload the pressure values collected in real time to the washing machine operation system. In addition, the preset position can be determined according to the position of the pressure sensor which is uniformly distributed on the washing machine base, so that the pressure value which is acquired according to the pressure sensor which is uniformly distributed on the washing machine base is convenient to follow up and accords with the preset range, and the washing machine is ensured to be in a stable running state.
In an optional embodiment, pressure sensors are respectively arranged at four bottom corners of a base of the washing machine, and the pressure sensors acquire the pressure applied to the bottom corners in real time and upload the pressure values to an operation system of the washing machine; the washing machine operation system receives the pressure value uploaded by the pressure sensor, so that the current balance state of the washing machine can be known in time, and whether the washing machine continues to operate stably or not is judged.
In an optional embodiment, after the operating system receives the pressure values collected by the pressure sensors and before comparing the pressure values uploaded by the pressure sensors with the preset ranges, the method includes: the pressure value is converted from the signal to a numerical value, thereby facilitating comparison of the numerical pressure value with a preset range.
Step S02, comparing the pressure value of each pressure sensor with a preset range, judging whether the pressure value of the pressure sensor can be adjusted to the preset range by adjusting the height of the base angle based on the fact that the pressure value uploaded by any pressure sensor is out of the preset range, and controlling to adjust the height of the base angle if the pressure value is out of the preset range; otherwise, sending pressure alarm to the display panel and stopping the operation of the washing machine.
In this embodiment, the operation system of the washing machine needs to compare the pressure values uploaded by the pressure sensors with a preset range, and if the pressure values of all the pressure sensors are within the preset range, the washing machine continues to operate normally; otherwise, the washing machine operation system is required to analyze the specific situation to judge which way to solve the problem that the pressure value does not conform to the preset range, and the method specifically comprises the following steps: the operation system judges whether the pressure value of the pressure sensor can be adjusted to be within a preset range by adjusting the height of the base angle, and if so, the operation system controls and adjusts the height of the base angle; otherwise, sending pressure alarm to the display panel and stopping the operation of the washing machine.
More specifically, comparing the pressure values uploaded by the pressure sensors with a preset range respectively includes: respectively and correspondingly setting preset ranges according to the preset positions; and comparing the pressure values acquired by the pressure sensors at the preset positions with the corresponding preset ranges respectively based on a preset range. It should be noted that, in the preset ranges corresponding to the preset positions, at least three preset ranges are different, or at least three preset ranges are the same. In addition, the preset range can be calculated based on factors such as the actual operation scene of the washing machine, the weight of the washing machine, the placing position of the washing machine, the actual pressure bearing of the preset position corresponding to the preset range, the scene where the preset position is located and the like, and the preset range is not further limited in the application.

It should be noted that the adjusted height of the base angle is the height that the base angle needs to be increased or decreased. In addition, if the preset position and the bottom corner are at the same position, the adjusting height of the preset position is the adjusting height of the bottom corner.
In an alternative embodiment, after the operating system sends the height and direction of adjustment of the base corner to the height of adjustment of the base corner, the base corner receives the height and direction of adjustment and adjusts in the direction of adjustment by the height of adjustment so that the adjusted height is equal to the sum of the current height and the height of adjustment.
