Description

Technical Field

[0001] This application relates to the field of washing machine technology, specifically to a method, apparatus, and storage medium for detecting the eccentricity of a washing machine. Background Technology

[0002] Most washing machines have large-capacity inner drums. When the inner drum operates at high speed and high acceleration, uneven load can easily cause the washing machine to become eccentric, leading to drum collisions or large displacements, affecting the stability and safety of the washing machine. Therefore, testing the washing machine's anti-eccentricity capability (i.e., the maximum permissible amount of eccentricity) is very important. Summary of the Invention

[0003] This application provides a method, apparatus, and storage medium for detecting the eccentricity of a washing machine, with the aim of providing a method for detecting the anti-eccentricity capability of a washing machine.

[0004] Firstly, this application proposes a method for detecting the eccentricity of a washing machine, comprising:

[0005] S100, control the inner drum of the washing machine to rotate at a preset angular acceleration; wherein, an eccentric block is provided inside the inner drum;

[0006] S200, obtain the displacement;

[0007] S300, determine whether the displacement is greater than a preset displacement value or whether the inner cylinder hits the barrel;

[0008] S400, if the displacement is less than the preset displacement value and the inner drum does not collide with the drum, then control the inner drum of the washing machine to stop rotating;

[0009] After replacing the eccentric block inside the inner cylinder, steps S100, S200, and S300 are repeated until the displacement is greater than the displacement value or the inner cylinder hits the barrel; wherein, the weight of the replaced eccentric block is greater than the weight of the previous eccentric block.

[0010] S500, if the displacement is greater than the preset displacement value or the inner drum hits the drum, then the eccentricity of the washing machine is determined to be the weight of the eccentric block finally placed in the inner drum.

[0011] Optionally, the preset angular acceleration includes a first angular acceleration, which is used to increase the rotational speed of the inner cylinder from a first rotational speed to a second rotational speed; wherein the first rotational speed and the second rotational speed are located in the low rotational speed range of the inner cylinder.

[0012] Optionally, the preset angular acceleration includes a second angular acceleration, which is used to increase the inner drum of the washing machine from a third rotational speed to a fourth rotational speed; wherein the third rotational speed and the fourth rotational speed are within the resonant rotational speed range of the inner drum.

[0013] Optionally, the preset angular acceleration includes a third angular acceleration, which is used to increase the inner drum of the washing machine from a fifth rotational speed to a sixth rotational speed; wherein the fifth rotational speed is in the low rotational speed range of the inner drum, and the sixth rotational speed is in the resonant rotational speed range of the inner drum.

[0014] Optionally, the difference between the weight of the replaced eccentric block and the weight of the previous eccentric block is a preset weight increment.

[0015] Optionally, the eccentricity is a pre-eccentricity; during measurement, the eccentric block is located on the front side of the inner cylinder.

[0016] Optionally, the eccentricity is a diagonal eccentricity; during measurement, the inner cylinder is provided with two eccentric blocks of the same weight, and the two eccentric blocks of the same weight are arranged diagonally.

[0017] Optionally, in S400, if the displacement is less than the preset displacement value and the inner drum does not collide with the drum, controlling the inner drum of the washing machine to stop rotating includes:

[0018] If the displacement is less than the preset displacement value and the inner drum does not collide with the drum, the angular acceleration of the inner drum of the washing machine is increased, and it resumes accelerated rotation according to the increased angular acceleration.

[0019] Repeat steps S200 and S300;

[0020] If the displacement after increasing the angular acceleration is less than the preset displacement value and the inner drum does not collide with the drum, then control the inner drum of the washing machine to stop rotating;

[0021] S500, if the displacement is greater than a preset displacement value or the inner drum collides with the drum, then determining the eccentricity of the washing machine as the weight of the eccentric block finally placed in the inner drum includes:

[0022] If the displacement after increasing angular acceleration is greater than the preset displacement value or the inner drum hits the drum, then the eccentricity of the washing machine is determined to be the weight of the eccentric block finally placed in the inner drum.

[0023] Secondly, this application also proposes an eccentricity detection device for a washing machine, the device comprising:

[0024] The control module is used to execute step S100, controlling the inner drum of the washing machine to rotate according to a preset angular acceleration; wherein, an eccentric block is provided inside the inner drum;

[0025] The acquisition module is used to execute step S200 and acquire the displacement.

[0026] The judgment module is used to execute step S300 to determine whether the displacement is greater than a preset displacement value or whether the inner cylinder has collided with the barrel.

[0027] The control module is used to execute step S400. If the displacement is less than the preset displacement value and the inner drum does not collide with the drum, the control module controls the inner drum of the washing machine to stop rotating. The control module is used to re-execute steps S100, S200, and S300 after replacing the eccentric block inside the inner drum, until the displacement is greater than the displacement value or the inner drum collidees with the drum. The weight of the replaced eccentric block is greater than the weight of the previous eccentric block.

[0028] The determination module is used to execute step S500. If the displacement is greater than a preset displacement value or the inner drum hits the drum, the eccentricity of the washing machine is determined to be the weight of the eccentric block finally placed in the inner drum.

[0029] Thirdly, this application also proposes a computer-readable storage medium having a computer program stored thereon, the computer program being loaded by a processor to perform the steps in the aforementioned method for detecting the eccentricity of a washing machine.

[0030] In this application, before performing the eccentricity detection method, an eccentric block is placed inside the inner drum. Then, the inner drum of the washing machine is controlled to rotate at a preset angular acceleration, and the displacement is acquired. The weight of the eccentric block is determined by whether the displacement is greater than a preset displacement value or whether the inner drum collidees with the drum. If the displacement is less than the preset displacement value and the inner drum does not collide with the drum, the weight of the eccentric block is not the eccentricity of the inner drum. Therefore, the inner drum is stopped rotating, and a heavier eccentric block is replaced. Steps S300, S400, and S500 are repeated. This process is repeated until the displacement is greater than the preset displacement value or the inner drum collidees with the drum. At this point, the eccentricity of the washing machine is determined to be the weight of the last eccentric block placed in the inner drum, thus detecting the eccentricity capability of the washing machine.

In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0040] This application provides a method, apparatus, and storage medium for detecting the eccentricity of a washing machine, which will be described in detail below.

[0041] The washing machine in this application embodiment can be a washing machine with only washing function, a dryer with only drying function, or a washer-dryer combo that combines washing and drying functions.

[0042] like Figure 1 , Figure 3 and Figure 4 The diagram shown is a flowchart of an embodiment of the eccentricity detection method for a washing machine according to this application. The eccentricity detection method for the washing machine includes:

[0043] S100, control the inner drum of the washing machine to rotate at a preset angular acceleration; wherein, the inner drum is provided with an eccentric block 01;

[0044] S200, obtain the displacement;

[0045] S300, determine 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 collide with the drum, then control the inner drum of the washing machine to stop rotating;

[0047] After replacing the eccentric block 01 inside the inner cylinder, steps S100, S200, and S300 are repeated 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 the preset displacement value or the inner drum hits the drum, then the eccentricity of the washing machine is determined to be the weight of the eccentric block 01 placed in the inner drum last.

[0049] In the technical solution of this application embodiment, before performing the eccentricity detection method, an eccentric block 01 is set inside the inner drum; then, the inner drum of the washing machine is controlled to rotate at a preset angular acceleration, and the displacement is obtained; by checking whether the displacement is greater than a preset displacement value or whether the inner drum hits the drum, it is determined 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 drum, then the weight of the eccentric block 01 is not the eccentricity of the inner drum, so the inner drum is stopped rotating, and a heavier eccentric block 01 is replaced, repeating steps S300, S400, and S500. This process is repeated until the displacement is greater than the preset displacement value or the inner drum hits the drum, at which point the eccentricity of the washing machine is determined to be the weight of the eccentric block 01 finally placed in the inner drum, thus obtaining the eccentricity capability of the washing machine.

[0050] For example, in one embodiment, an eccentric block 01 of weight W1 is first placed in the inner drum; the rotational speed of the inner drum is increased by a preset angular acceleration, and the displacement is obtained; if the displacement is less than a preset displacement value and the inner drum does not collide with the drum, the inner drum is controlled to stop rotating. Then, an eccentric block 01 of weight W2 (W2 is greater than W1) is placed in the inner drum a second time, and the rotational speed of the inner drum is increased by a preset angular acceleration, and the displacement is obtained; if the displacement is greater than a preset displacement value or the inner drum collidees with the drum, the eccentricity of the washing machine is determined to be the weight W2 of the last eccentric block 01 placed in the inner drum.

[0051] In the above embodiments, the collision of the inner cylinder with the outer cylinder can be determined by a pressure sensor. For example, a pressure sensor is installed on the inner cylinder. When the inner cylinder collidees with the outer cylinder, the pressure sensor impacts the outer cylinder, thus determining that the inner cylinder has collided. The collision can also be determined by a sound sensor. For example, a sound sensor is installed on the outer cylinder. By comparing the collected sound with the normal sound set by the system, when the inner cylinder collides, the sound is an impact sound, which is compared with the normal sound of the inner cylinder not collided, thus determining that the inner cylinder has collided. In other embodiments, the collision detection can be input by the operator into the detection system; for example, if the operator detects that the inner cylinder has collided during testing, they input the corresponding collision information into the detection system, and the system then determines that the inner cylinder has collided.

[0052] In the above embodiments, the washing machine is equipped with a displacement sensor, which can measure the displacement of the washing machine. In some embodiments, the displacement sensor can also be installed on a fixed device outside the washing machine, and the displacement sensor measures the displacement of the washing machine relative to the fixed device, thereby determining the displacement of the washing machine.

[0053] In the above embodiments, the weight of the eccentric block 01 initially placed can be adapted to the capacity of the inner cylinder. For example, numerically, the weight (g) of the eccentric block 01 initially placed can be 1 / 20, 1 / 25, or 1 / 30 of the inner cylinder capacity (mL) as an initial test.

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

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

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

[0057] As an optional implementation of the above embodiments, the difference between the weight of the replaced eccentric block 01 and the weight of the previous eccentric block 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 collide with the barrel, then in the next eccentricity detection, the weight of the eccentric block 01 will be increased by the preset weight increment based on the weight of the previous eccentric block 01.

[0058] As an optional implementation of the above embodiments, combined with Figure 3 As shown, the eccentricity is the pre-eccentricity; during measurement, the eccentric block 01 is located on the front side of the inner cylinder. In an embodiment, when performing pre-eccentricity detection, the eccentric block 01 is located on the front side of the inner cylinder, for example, on the right side of the lifting rib near the front of the barrel.

[0059] As an optional implementation of the above embodiments, combined with Figure 4As shown, the eccentricity is a diagonal eccentricity. During measurement, the inner drum is equipped with two eccentric blocks 01 of equal weight, and the two eccentric blocks 01 of equal weight are arranged diagonally. In an embodiment, when detecting the diagonal eccentricity, two eccentric blocks 01 of equal weight are placed on the right side of the washing machine's lifting rib near the front of the drum (same as the position of the front eccentric block), and then another eccentric block 01 is placed directly above the front eccentric block and behind the drum, thus the two eccentric blocks 01 are arranged diagonally.

[0060] like Figure 2 As shown, in the above embodiment, S400, if the displacement is less than the preset displacement value and the inner drum does not collide with the drum, then 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 collide with the drum, control the angular acceleration of the inner drum of the washing machine to increase, and restart the accelerated rotation according to the increased angular acceleration.

[0062] Repeat steps S200 and S300;

[0063] S420, if the displacement after increasing angular acceleration is less than the preset displacement value and the inner drum does not collide with the drum, then control 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 drum, then the eccentricity of the washing machine is determined to be the weight of the eccentric block 01 finally placed in the inner drum, including:

[0065] S510, if the displacement after increasing angular acceleration is greater than the preset displacement value or the inner drum hits the drum, then 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 operation, especially during the spin-drying process, washing machines can use different accelerations to increase the rotation speed. Therefore, in the technical solution of this application embodiment, after placing the eccentric block 01 in the inner drum, the rotation speed is first increased with a smaller angular acceleration. It is then determined whether the displacement is greater than a preset displacement value or whether the inner drum is hitting the drum. If the displacement is less than the preset displacement value and the inner drum is not hitting the drum, the washing machine is controlled to increase the rotation speed with a larger angular acceleration, and then it is determined whether the displacement is greater than the preset displacement value or whether the inner drum is hitting the drum. If the displacement is greater than the preset displacement value or the inner drum is hitting the drum, the eccentricity of the washing machine is equal to the weight of the eccentric block 01. Furthermore, the washing machine can be set to increase the rotation speed with the smaller angular acceleration when the load weight is equal to or close to the weight of the eccentric block 01, but not with the larger angular acceleration.

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

[0068] In 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, which is different from the different tolerances of different models of washing machines to eccentricity. This helps to further improve the performance of the washing machine in the later stages of development, helps to prevent the washing machine from shifting or hitting the drum, and helps to maximize the utilization of the washing machine.

[0069] To better implement the eccentricity detection method for washing machines in this application embodiment, based on the eccentricity detection method for washing machines, this application embodiment also provides an eccentricity detection device for washing machines, such as...

[0072] Judgment module 30 is used to execute step S300 to determine whether the displacement is greater than a preset displacement value or whether the inner cylinder hits the barrel.

[0073] The control module 10 is used to execute step S400. If the displacement is less than the preset displacement value and the inner drum does not collide with the drum, the control module controls the inner drum of the washing machine to stop rotating. The control module is used to re-execute steps S100, S200, and S300 after replacing the eccentric block inside the inner drum, until the displacement is greater than the displacement value or the inner drum collidees with the drum.
