The inventors of the present application have found through research that when a lighter garment, such as a dry sock, is placed in the inner tub of the washing machine, the weighing value detected by the weighing device is close to 0, or even 0, but the detected weight under the same state The imbalance value is more obvious.

Based on the above findings, an embodiment of the present application proposes a weighing calibration method for a laundry treatment device.

Referring to FIG. 1, in an embodiment of the present application, the method includes:

S101 obtains a weighing value and an out-of-balance (Out-Of-Balance, OOB) value detected by a weighing device in a clothes treatment device, and determines whether the clothes treatment device is in an empty state according to the obtained weighing value and out-of-balance value Drum state (that is, the state in which no clothes are placed in the inner drum of the laundry treatment device);

Ideally, when the laundry treatment device is in an empty drum state, the weighing value and unbalance value detected by the weighing device are 0;

S102: Record the weighing value obtained when the laundry treatment device is in an empty drum state as the empty drum weighing value, and perform the weighing value detected by the weighing device during the clothes treatment process according to the empty drum weighing value. calibration.

In the technical solution of the embodiment of the present application, the weighing value and the unbalance value detected by the weighing device in the laundry processing device are obtained, and whether the laundry processing device is in an empty cylinder state is determined according to the obtained weighing value and the unbalanced value. , the accuracy of the obtained empty cylinder weighing value can be increased by detecting whether the clothes processing device is in an empty cylinder state; the weighing value obtained when the clothes processing device is in an empty cylinder state can be recorded as the empty cylinder weighing value, The weighing value detected by the weighing device during the laundry processing process is calibrated according to the empty cylinder weighing value, and the weighing value detected by the weighing device during the laundry processing process is calibrated through the empty cylinder weighing value. Calibration can improve weighing accuracy and user experience.

In an optional embodiment of the present application, the clothes treatment device may be a washing machine, and the weighing device of the clothes treatment device may be a motor assembly of the washing machine; for a frequency conversion washing machine, the motor assembly includes a frequency converter and a motor.

In an optional embodiment of the present application, the above-mentioned method is performed by a control unit in the clothes treating apparatus; the control unit may be in the form of a control chip, a processor, or the like.

In an optional embodiment of the present application, judging whether the laundry treatment device is in an empty cylinder state according to the acquired weighing value and unbalanced value includes: verifying whether the weighing value is less than an empty cylinder weighing pre-set value. set value, and whether the unbalance value is smaller than the empty drum unbalance preset value, if both are smaller, it is confirmed that the laundry treatment device is in an empty drum state. The empty cylinder preset value of the weighing value and the empty cylinder preset value of the unbalanced value can be set according to the empirical value or simulation results, such as the empty cylinder preset value of the weighing value and the empty cylinder preset value of the unbalanced value. Both are set to 20, and the preset value of the empty cylinder of the weighing value and the preset value of the empty cylinder of the unbalanced value may be different.

In an optional embodiment of the present application, the obtaining the weighing value and the unbalance value detected by the weighing device of the clothes treating device includes: when the clothes treating device runs a preset program, obtaining the weighing value and the unbalance value of the clothes treating device. For the weighing value and unbalance value detected by the weighing device, the preset program is set as a program running in an empty cylinder state. The inventors of the present application have found through many experiments that if a light-weight laundry (such as a dry sock) is placed in the laundry treatment device, the unbalance detected when the laundry treatment device is running a program (such as a washing machine motor running a washing program) is unbalanced. The value increases significantly relative to the unbalance value detected when the clothes processing device is stationary and not running the program. Based on the above test results, in the embodiment of the present application, the clothes treatment device runs a program set to run in an empty cylinder state to obtain the weighing value and unbalance value detected by the weighing device of the clothes treatment device, which can improve the use of the weighing device. The accuracy of empty cylinder judgment with weight value and unbalance value.

The inventor of the present application also found that the weighing calibration program is usually a function program set separately on the machine, and it is up to the user to decide whether to use it, which may cause the user to frequently use the weighing calibration program. Frequent use of the weighing calibration procedure can easily lead to over-calibration by weighing calibration before the machine is experiencing weighing errors. In an optional embodiment of the present application, an existing tub self-cleaning program in the functional program of the laundry treatment device is used as the program set to run in an empty tub state. Since the drum self-cleaning program does not need to place any clothes during operation, it satisfies the condition that the weighing calibration runs in an empty drum state; in addition, considering that the weighing calibration program itself does not require high-frequency execution, optionally, the laundry treatment device The weighing calibration procedure is performed only after using the normal laundry treatment procedure for a period of time, so the infrequently used tub self-cleaning procedure can also meet the requirement of low usage frequency for weighing calibration. In this embodiment, the self-cleaning program of the drum is used as the program that is set to run in the empty drum state, and the weighing calibration can be completed while the user is performing the self-cleaning of the drum, which avoids additionally setting the weighing calibration function on the laundry treatment device. , which can simplify the number of control keys on the operation panel of the laundry treatment device without losing the function, and also simplifies the user's operation.

In addition to using the drum self-cleaning program as the program set to run in the empty drum state, as an optional embodiment of the present invention, other existing clothes treatment programs that the clothes treatment device runs in the empty drum state can also be used as A program that runs in an empty canister state.

In an optional embodiment of the present application, the acquiring the weighing value and the unbalance value detected by the weighing device of the laundry treatment device includes: running a tub self-cleaning program in the laundry treatment device and the laundry treatment device When the normal laundry processing program has been run for a preset number of times, the weighing value and the unbalance value detected by the weighing device of the laundry processing device are acquired. This embodiment stipulates that the premise of acquiring the weighing value and the unbalance value detected by the weighing device of the laundry treatment device not only requires the laundry treatment device to run the tub self-cleaning program, but also stipulates that the laundry treatment device runs a normal laundry treatment program that has reached a pre-condition. Set the number of times to avoid frequent weighing and calibration of the laundry treatment device caused by the frequent use of the drum self-cleaning program.

In an optional embodiment of the present application, recording the weighing value obtained when the laundry treatment device is in an empty drum state as the empty drum weighing value includes: recording the weight value used for judging that the clothes treatment device is in an empty drum state. The weight value is recorded as the empty cylinder weight value; this operation can shorten the time for weighing calibration.

In another optional embodiment of the present application, recording the weighing value obtained when the clothes treatment device is in an empty drum state as the empty drum weighing value may include: judging that the clothes treatment device is in an empty drum state, Continue to acquire the weighing value detected by the weighing device of the laundry treatment device, and determine the weighing value of the empty cylinder according to the continuously acquired weighing value. This embodiment can improve the compatibility of the program for realizing the weighing calibration method in the embodiment of the present application and the existing weighing program of the laundry treatment device. Taking the frequency conversion washing machine as an example, when it is judged that the frequency conversion washing machine is in the empty drum state through the weighing value and the unbalance value detected by the frequency conversion motor running at the first speed state, the frequency conversion motor can continue to run at the second speed state. , and the weighing value detected in the second rotational speed state is determined as the empty cylinder weighing value, and the first rotational speed state and the second rotational speed state are different.

In another optional embodiment of the present application, the continuing to acquire the weighing value detected by the weighing device in the laundry treatment device, and determining the weighing value of the empty cylinder according to the continuously acquired weighing value includes: continuing to acquire the weighing value The weighing value of the preset number detected by the device is determined according to the weighing value of the preset number of empty cylinders, and the preset number is an integer greater than or equal to 2. In order to improve the accuracy of the empty cylinder weighing value obtained when the laundry processing device is in an empty cylinder state, and reduce the adverse effects caused by the inaccurate empty cylinder weighing value obtained through one detection, you can continue to acquire multiple weighing values, and The weighing value of the empty cylinder is determined according to the multiple weighing values, for example, the average value of the multiple weighing values is recorded as the weighing value of the empty cylinder. Taking the frequency conversion washing machine as an example, when it is judged that the frequency conversion washing machine is in the empty drum state by the weighing value and the unbalance value detected by the frequency conversion motor running at the first speed state, the frequency conversion motor can be continued to run at the second speed respectively. state and third rotational speed state, and determine the empty cylinder weighing value according to the weighing value detected in the second rotational speed state and the third rotational speed state, the first rotational speed state, the second rotational speed state and the third rotational speed state Are not the same.

In an optional embodiment of the present application, the weighing value and the unbalanced value used for judging whether the laundry treatment apparatus is in an empty drum state may be multiple pairs of weighing values and unbalanced values. Optionally, when the clothes treating apparatus runs a preset program, acquire multiple weight values and unbalance values detected by a weighing device of the clothes treating apparatus. The weighing value and the unbalanced value detected by the weighing device at one time are a pair of the weighing value and the unbalanced value. In this embodiment, by acquiring multiple weight values and unbalance values detected by the weighing device of the laundry treatment device, it is possible to avoid inaccurate weight values and unbalance values obtained by one weighing detection, thereby affecting the accuracy of the judgment of the empty cylinder state. (For example, judging a non-empty cylinder state as an empty cylinder state). For the variable-frequency clothes treatment device, the multiple weight values and unbalance values can also be obtained through multiple variable-speed rotations, so that the values can be obtained in more diverse working environments, and the accuracy of the obtained values can be more improved, thereby improving the The accuracy of the judgment of the empty cylinder state.

In an optional embodiment of the present application, when there are multiple pairs of weight values and unbalance values, verify whether the weight value in each pair is less than the preset value of the empty cylinder weighing, and whether the unbalance value is less than the unbalance of the empty cylinder Preset value, in response to the weighing value being less than the empty cylinder weighing preset value and the unbalance value being less than the empty cylinder unbalance preset value, confirming that the laundry treatment device is in an empty cylinder state, including: Each pair of weighing value and unbalance value is verified, and when the verification result of each pair is that the weighing value is less than the preset value of empty cylinder weighing, and the unbalance value is less than the preset value of unbalanced empty cylinder, then the laundry is confirmed. The processing unit is in an empty cylinder state.

In yet another optional embodiment of the present application, when there are multiple pairs of weight values and unbalance values, it is respectively verified whether the weight values and unbalance values of each pair are both smaller than the respective preset values of the empty cylinder, and if the If the weighing value is less than the preset value of the empty cylinder weighing and the unbalance value is less than the preset value of the unbalanced empty cylinder, then confirming that the laundry treatment device is in the empty cylinder state, including: respectively weighing the multiple weighing values and the multiple unbalanced values. The value is averaged, and when the average value of weighing is less than the preset value of empty cylinder weighing, and the average value of unbalance is less than the preset value of unbalanced empty cylinder, it is confirmed that the laundry treatment device is in an empty cylinder state.

In an optional embodiment of the present application, calibrating the weighing value detected by the weighing device during the laundry processing process according to the empty cylinder weighing value includes: calculating the empty cylinder weighing value and a preset empty cylinder weighing value. The difference between the drum values, and the actual weighing value of the laundry treatment device is calibrated according to the difference; the preset empty drum value is generally placed in the running program of the clothes treatment device in a preset manner before the clothes treatment device leaves the factory. , ideally 0. In actual operation, the difference between the empty cylinder weighing value and the preset empty cylinder value may be 0, may be a positive value, or may be a negative value. When the difference is 0, the actual weighing value of the laundry treatment device is not calibrated; when the difference is positive, the actual weighing value of the laundry treatment device can be increased according to the difference; when the difference is positive When it is a negative value, the actual weighing value of the laundry treatment device can be reduced according to the difference.
