Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0040] The embodiments of the present application provide a method, device and storage medium for detecting the eccentricity of a washing machine, which are described in detail below.

[0041] The washing machine in the embodiment of the present application may be a washing machine with only a washing function, a drying machine with only a drying function, or a washer-dryer with both washing and drying functions.

[0042] like Figure 1 , Figure 3 and Figure 4 FIG. 1 is a flow chart of an embodiment of a method for detecting the eccentricity of a washing machine in an embodiment of the present application. The method for detecting the eccentricity of a washing machine includes:

[0043] S100, controlling the inner drum of the washing machine to accelerate the rotation according to a preset angular acceleration; wherein an eccentric block 01 is provided in the inner drum;

[0044] S200, obtaining displacement;

[0045] S300, determining whether the displacement is greater than a preset displacement value or whether the inner cylinder hits the barrel;

[0046] S400, if the displacement is less than the preset displacement value and the inner drum does not hit the tub, controlling the inner drum of the washing machine to stop rotating;

[0047] After the eccentric block 01 in the inner cylinder is replaced, steps S100, S200, and S300 are performed again until the displacement is greater than the displacement value or the inner cylinder hits the barrel; wherein the weight of the replaced eccentric block 01 is greater than the weight of the previous eccentric block 01;

[0048] S500: If the displacement is greater than a preset displacement value or the inner drum collides with the tub, the eccentricity of the washing machine is determined to be the weight of the eccentric block 01 last placed in the inner drum.

[0049] In the technical solution of the embodiment of the present application, before the eccentricity detection method is performed, an eccentric block 01 is set in the inner drum; then the inner drum of the washing machine is controlled to accelerate and rotate according to the preset angular acceleration, and the displacement is obtained; by whether the displacement is greater than the preset displacement value or whether the inner drum hits the barrel, it is judged whether the weight of the eccentric block 01 is the eccentricity of the inner drum. If the displacement is less than the preset displacement value and the inner drum does not hit the barrel, the weight of the eccentric block 01 is not the eccentricity of the inner drum, so the inner drum is controlled to stop rotating, and the eccentric block 01 with a heavier weight is replaced, and steps S300, S400 and S500 are repeated. In this way, the reciprocating cycle is performed until the displacement is greater than the preset displacement value or the inner drum hits the barrel, then the eccentricity of the washing machine is determined to be the weight of the eccentric block 01 last placed in the inner drum, so as to obtain the eccentricity capacity of the washing machine.

[0050] For example, in one embodiment, the eccentric block 01 with a weight of W1 is placed in the inner drum for the first time; the speed of the inner drum is increased at a preset angular acceleration, and the displacement is obtained at this time; and it is determined that the displacement is less than the preset displacement value and the inner drum does not hit the barrel, then the inner drum is controlled to stop rotating. At this time, the eccentric block 01 with a weight of W2 is placed in the inner drum for the second time (W2 is greater than W1), and the speed of the inner drum is increased at a preset angular acceleration, and the displacement is obtained at this time; and it is determined that the displacement is greater than the preset displacement value or the inner drum hits the barrel, then the eccentricity of the washing machine is determined to be the weight W2 of the eccentric block 01 last placed in the inner drum.

[0051] In the above embodiment, the inner cylinder hitting the barrel can be judged by a pressure sensor. For example, a pressure sensor is provided on the inner cylinder. When the inner cylinder hits the barrel, the pressure sensor hits the outer cylinder, and it is judged that the inner cylinder hits the barrel. The inner cylinder hitting the barrel can also be judged by a sound sensor. For example, a sound sensor is provided on the outer cylinder, and by comparing the collected sound with the normal sound set by the system, when the inner cylinder hits the barrel, the sound is an impact sound, which is compared with the normal sound of the inner cylinder without hitting the barrel, and it is judged that the inner cylinder hits the barrel. In some other embodiments, the inner cylinder hitting the barrel can be input into the detection system by the implementer; for example, when the implementer is testing, if it is determined that the inner cylinder hits the barrel, the corresponding information of the barrel collision is input into the detection system, and the system determines that the inner cylinder hits the barrel.

[0052] In the above embodiment, a displacement sensor is provided on the washing machine, and the displacement of the washing machine can be measured by the displacement sensor. In some embodiments, a displacement sensor can also be installed on a fixture outside the washing machine, and the displacement sensor measures the displacement of the washing machine relative to the fixture, thereby determining the displacement of the washing machine.

[0053] In the above embodiment, the weight of the eccentric mass 01 placed for the first time can be adapted according to the capacity of the inner cylinder. For example, in terms of numerical value, the weight (g) of the eccentric mass 01 placed for the first time is 1 / 20, 1 / 25 or 1 / 30 of the capacity (mL) of the inner cylinder for initial detection.

[0054] In the technical solution of the above embodiment, the preset angular acceleration includes a first angular acceleration, and the first angular acceleration is used to increase the rotation speed of the inner drum from a first rotation speed to a second rotation speed; wherein the first rotation speed and the second rotation speed are located in a low rotation speed range of the inner drum. That is, the eccentricity detection is an eccentricity detection of a low rotation speed of the washing machine.

[0055] In the technical solution of the above embodiment, the preset angular acceleration includes a second angular acceleration, and the second angular acceleration is used to increase the inner drum of the washing machine from a third speed to a fourth speed; wherein the third speed and the fourth speed are in the resonance speed range of the inner drum. That is, the eccentricity detection is the eccentricity detection in the resonance range of the washing machine.

[0056] In the technical solution of the above embodiment, the preset angular acceleration includes a third angular acceleration, and the third angular acceleration is used to increase the inner drum of the washing machine from a fifth speed to a sixth speed; wherein the fifth speed is in a low speed range of the inner drum, and the sixth speed is in a resonance speed range of the inner drum. That is, the eccentricity detection is an eccentricity detection of the washing machine transitioning from a low speed range to a resonance range.

[0057] As an optional implementation of the above embodiment, the difference between the weight of the replaced eccentric mass 01 and the weight of the previous eccentric mass 01 is a preset weight increment. In this embodiment, after the previous eccentricity detection, if the displacement is less than the preset displacement value and the inner cylinder does not hit the barrel, the weight of the eccentric mass 01 is increased by the preset weight increment based on the weight of the previous eccentric mass 01 during the next eccentricity detection.

[0058] As an optional implementation of the above embodiment, Figure 3 As shown, the eccentricity is the front eccentricity; when measuring, the eccentric block 01 is arranged at the front side of the inner tube. In the embodiment, when the front eccentricity is detected, the eccentric block 01 is arranged at the front side of the inner tube, such as the right side of the lifting rib close to the front of the barrel.

[0059] As an optional implementation of the above embodiment, Figure 4As shown, the eccentricity is the diagonal eccentricity; when measuring, the inner drum is provided with two eccentric blocks 01 of the same weight, and the two eccentric blocks 01 of the same weight are arranged diagonally. In the embodiment, when testing the diagonal eccentricity, two eccentric blocks 01 of the same weight are placed at the right side of the lifting rib of the washing machine near the front of the barrel body (the same as the position of the front eccentricity), and another eccentric block 01 is placed just above the front eccentricity and at the rear of the barrel body, so that the two eccentric blocks 01 are arranged diagonally.

[0060] like Figure 2 As shown, in the above embodiment, at S400, if the displacement is less than the preset displacement value and the inner drum does not hit the tub, controlling the inner drum of the washing machine to stop rotating includes:

[0061] S410, if the displacement is less than the preset displacement value and the inner drum does not hit the tub, controlling the angular acceleration of the inner drum of the washing machine to increase, and restarting the rotation according to the accelerated rotation after the angular acceleration is increased;

[0062] Re-execute step S200 and step S300;

[0063] S420, if the displacement after the angular acceleration is increased is less than the preset displacement value and the inner drum does not hit the tub, controlling the inner drum of the washing machine to stop rotating;

[0064] S500, if the displacement is greater than a preset displacement value or the inner drum hits the tub, determining the eccentricity of the washing machine as the weight of the eccentric block 01 last placed in the inner drum comprises:

[0065] S510, if the displacement after adding the angular acceleration is greater than the preset displacement value or the inner drum collides with the tub, the eccentricity of the washing machine is determined to be the weight of the eccentric block 01 finally placed in the inner drum.

[0066] During the operation of the washing machine, especially during the dehydration process, different accelerations can be used to increase the speed. To this end, in the technical solution of the embodiment of the present application, after the eccentric block 01 is placed in the inner drum, the speed is first increased with a smaller angular acceleration to determine whether the displacement is greater than the preset displacement value or whether the inner drum hits the barrel; if the displacement is less than the preset displacement value and the inner drum does not hit the barrel, the washing machine is controlled to increase the speed with a larger angular acceleration, and then determine whether the displacement is greater than the preset displacement value or whether the inner drum hits the barrel; if the displacement is greater than the preset displacement value or the inner drum hits the barrel, the eccentricity of the washing machine is the weight of the eccentric block 01; and the washing machine can be set as follows: when the weight of the load is or is close to the weight of the eccentric block 01, the washing machine can increase the speed with the smaller angular acceleration, but is not allowed to increase the speed with the larger angular acceleration.

[0067] When the washing machine is controlled to use a larger angular acceleration to increase the speed, if the displacement is less than the preset displacement value and the inner drum does not hit the barrel, the eccentric block 01 is replaced with an eccentric block 01 with a larger mass to complete subsequent detection until the inner drum hits the barrel or the displacement is greater than the preset displacement value.

[0068] In the technical solution of the above embodiment, the anti-eccentricity ability of the washing machine can be measured by adding an eccentric block 01 of a certain weight according to a specific method, in view of the different eccentricity tolerance of different models of washing machines. This will help to further improve the performance of the washing machine in the later stage of development, prevent the washing machine from shifting and colliding with the barrel, and maximize the utilization of the washing machine.
