s1, weighing the load in the inner cylinder by adopting a first weighing way, wherein the weighing step of the first weighing way comprises the following steps:
s11, before the load is put into the inner barrel, the weighing module weighs the inner barrel and outputs a weight A0(ii) a After the user opens the washing and drying machine, the controller is electrified to calibrate the weight of the empty barrel once through the weighing module and output the weight A of the empty barrel0；
S12, after the load is put into the inner barrel, the weighing module weighs the inner barrel again and outputs a weight A1(ii) a Accurately weighing after a user adds a load, performing weighing detection again through the pressure sensor before washing when the motor does not rotate, and outputting weighing data A1；

In this embodiment, the second weighing approach may adopt a plurality of weighing manners, and one of the weighing manners may be: clothes weight B output by motor power after motor rotationn. The method specifically comprises the following steps: when the motor rotates, calculating the transient conduction angle of the motor; calculating the transient power consumed by the motor according to the transient conduction angle of the motor and the characteristic curve of the power supply signal of the motor; the transient power consumed by the motor is subjected to integral summation to obtain the work of the motor on a load; and finding the load weight corresponding to the work of the motor on the load according to the corresponding relation between the work and the load weight.
Another possible implementation is: controlling the washing and drying machine to rotate at a set rotating speed with the load weight larger than the centrifugal force, acquiring vibration data detected by a vibration sensor in the rotating process, calculating a first amplitude of an outer cylinder of the washing and drying machine in a first direction based on the vibration data, and searching a corresponding relation table of the amplitude and the load weight to determine the load weight corresponding to the first amplitude as the load weight; training according to a large amount of repeatedly tested data to obtain the corresponding relation between the amplitude and the load weight of the outer barrel of the washing and drying machine, acquiring the vibration data of the outer barrel of the washing and drying machine detected by the vibration sensor when the washing and drying machine rotates at a set rotating speed, calculating the amplitude generated by the vibration of the outer barrel of the washing and drying machine according to the vibration data, inquiring a corresponding relation table of the amplitude and the load weight, and accurately determining the load weight by combining the correction of a correction rule.
Yet another possible implementation is: firstly, controlling a motor to enable the motor to reach a first preset rotating speed, enabling the motor to rotate at a constant speed at the first preset rotating speed, and measuring the electric energy of a load driven by the motor at the moment; and finally, according to the detection result, subtracting a difference value obtained by multiplying the electric energy rotating at the constant speed at the first preset rotating speed by a time correction parameter from the rising electric energy of the motor rising from the first preset rotating speed to the second preset rotating speed, calculating corresponding load electric energy, and comparing the obtained load electric energy with a corresponding relation curve of the load electric energy and the load weight stored in a computer controller of the washing and drying machine after the correction step, thereby determining the most approximate weight data. The invention has high detection precision and short detection time.
In the embodiment, the load is weighed by adopting two weighing ways, so that the condition that the weighing data obtained by a single weighing way has a large error is avoided, and the weighing accuracy is ensured.
Further optionally, before step S3, the following steps are also performed:
s21, comparing the load weight DeltaA obtained by the first weighing way1With the load weight B obtained in the second weighing path1An error of (2);
s22, current Δ A1And B1When the error of (b) is within the allowable error range, S3 is executed;
s23, current Δ A1And B1When the error of (2) is out of the allowable error range, returning to S12; obtaining the load weight Delta A by a first weighing waynObtaining the load weight B by a second methodnN is the number of weighing times until delta AnAnd BnThe error value of (1) is within the allowable error range, and the final load weight M is output as (delta A)n+Bn)/2。
The embodiment compares the weighing data of the two weighing approaches, and if the difference between the data obtained by the two weighing approaches is not large, namely within an allowable error range, the weighing results of the two weighing approaches are accurate. If the difference of the weighing data obtained by the two weighing approaches is large, namely the weighing data exceeds the allowable error range, the two weighing approaches are adopted for weighing for multiple times until the error values of the two weighing approaches are within the allowable error range, so that the accuracy of the weighing result is ensured.
Further optionally, in step S23, after the number of weighing times n reaches the set number, if the load weight Δ a obtained by the first weighing pathnWith the load weight B obtained in the second weighing pathnIf the error of (a) is still beyond the allowable error range, the weighing data with the error value of the two weighing approaches closest to the allowable error range is selected from the n times of weighing to output the final load weight M, wherein M is equal to (delta A)i+Bi) And/2, wherein i is the weighing times when the error values of the two weighing ways are closest to the allowable error range, and i is less than or equal to n.
In order to avoid that the excessive weighing operation affects the subsequent washing time, the present embodiment prevents the excessive weighing times by setting the allowable maximum weighing times, i.e. the set times, and the set times can be adjusted according to the user's needs, and can also be directly set in the controller and can not be changed. For example, the maximum number of times of weighing is set to 5 times, and after 5 times of weighing is performed by adopting two weighing approaches, the results of the two times of weighing both exceed the allowable error range, and then the program selects and outputs one time of weighing data with the error closest to the allowable error range from the 5 times of weighing.
And finally, after the accurate weighing process is finished, calculating the washing time, the detergent putting amount and the first drying time according to the output final load weight, and then starting to enter a normal washing process.
