Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. 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.
[0020] During operation, garment processing equipment is prone to single-axis and diagonal eccentricity. Related technologies detect eccentricity within the washing drum by monitoring fluctuations in motor current or drum speed. However, this method struggles to effectively identify diagonal eccentricity, which can lead to vibration and noise, and even damage to the washing drum due to the failure to detect diagonal eccentricity.
[0021] In the technical solution of this application embodiment, by setting a sensor at the front bearing and detecting the mechanical parameters at the front bearing, diagonal eccentricity can be effectively identified. For example... Figure 1 As shown, a model is created for the diagonal eccentricity within the garment processing equipment. This eccentricity generates a centrifugal force F=mrω during the rotation of the washing drum. 2 In the formula, m is the eccentric mass, r is the eccentric radius of rotation (the inner diameter of the washing drum), and ω is the angular velocity of the drum.
[0022] The resultant torque generated by the diagonal eccentricity at the front support point A of the front bearing is: M=F F L F -F R L R = Frω 2 L F - Rrω 2 L R In the above formula, F F The eccentric force L is set at the front of the cylinder. F F is the axial distance between the front eccentricity and point A; R The eccentric force L is set at the front of the cylinder. R R is the axial distance between the rear eccentricity and point A. F is the eccentric mass set at the front of the cylinder, and R is the diagonal eccentricity set at the rear of the cylinder.
[0023] The deformation of the washing drum front end under different diagonal eccentricities was calculated by simulation, as shown in the table below.
[0024]
[0025] If diagonal eccentricity forms within the washing drum, the greater the deformation at the front end of the drum, the more severe the diagonal eccentricity (or the larger the diagonal eccentricity). The data in the table shows that the deformation at the front end of the washing drum (i.e., the load-bearing capacity of the washing drum) is directly proportional to the resultant torque of the diagonal eccentricity. In other words, the larger the diagonal eccentricity, the greater the resultant torque on the washing drum, and simultaneously, the greater the load applied to the bearing housing by the washing drum shaft through the bearing. Thus, a corresponding relationship exists between the diagonal eccentricity and the load borne by the bearing housing. Based on this, a sensor is installed between the front bearing and the bearing housing, positioned axially on the front bearing; for example, the sensor can be positioned on the left or right side of the front bearing to eliminate the influence of the weight of the washing drum and the load of the clothes inside, improving recognition accuracy. Therefore, this embodiment of the application determines the magnitude of the diagonal eccentricity by detecting the mechanical parameters of the sensor, and then controls the clothing processing equipment to execute an operating strategy corresponding to the diagonal eccentricity value.
[0026] like Figure 2 The illustration shows a washing drum 10 and its support structure for a garment processing device. The garment processing device includes a washing drum 10, a drive shaft 20, and a front bearing 30 and a rear bearing 40 mounted on the drive shaft 20. The garment processing device also includes a bearing housing 60. The drive shaft 20 drives the washing drum 10 to rotate; wherein, axially along the drive shaft 20, the front bearing 30 is located between the rear bearing 40 and the washing drum 10. The garment processing device also includes a sensor 50 for acquiring the mechanical characteristic values of the front bearing 30. The sensor 50 is disposed between the front bearing 30 and the radial clearance of the bearing housing 60.
[0027] like Figure 3 The diagram shown is a flowchart illustrating an embodiment of the control method for a garment processing device according to this application. The control method for the garment processing device includes: S300, Obtain the mechanical characteristic value; S400, determine the diagonal eccentricity value of the washing drum based on the mechanical characteristic value; S500, based on the diagonal eccentricity value, control the washing drum to execute the operating strategy corresponding to the diagonal eccentricity value.
[0028] In the technical solution provided in this application embodiment, by obtaining the mechanical characteristic value of the front bearing, the diagonal eccentricity value of the washing drum is determined based on this mechanical characteristic value, and then the washing drum is controlled to execute an operating strategy corresponding to the diagonal eccentricity value. If diagonal eccentricity is formed inside the washing drum, it will cause the mechanical characteristic value of the front bearing to change in the same direction as the diagonal eccentricity, thereby effectively identifying the diagonal eccentricity and controlling the washing drum to execute an operating strategy corresponding to the diagonal eccentricity value, so as to reduce vibration, noise and the risk of drum collision.
[0029] In some embodiments, step S500, controlling the washing drum to execute an operating strategy corresponding to the diagonal eccentricity value, based on the diagonal eccentricity value, includes one or more of the following: When the diagonal eccentricity exceeds the set threshold, the washing drum is controlled to perform a shaking action to redistribute the load or maintain the current speed of the washing drum (i.e., it is not allowed to continue to increase its speed to avoid collisions).
[0030] When the diagonal eccentricity value is less than the set threshold, the washing drum speed is increased to improve washing efficiency.
[0031] Reference Figure 4 As shown, Figure 4 A schematic diagram illustrating the specific process of a control method for a garment processing device is provided.
[0032] When the spin cycle begins, the washing drum performs one tumbling motion. This tumbling motion includes forward and reverse rotation of the washing drum, as well as changes in spin speed.
[0033] Then, the washing drum speed increases to the preset first speed. While the washing drum is running at the first speed, the controller first performs a single eccentricity (OOB) detection. If the single eccentricity detection value is less than the preset OOB value, the controller detects the diagonal eccentricity (DOOB) value by collecting the mechanical characteristic value of the pressure sensor. If the diagonal eccentricity (DOOB) value is less than the threshold set at the first speed, the controller controls the washing drum to increase to the second speed for spin-drying. When the washing drum reaches the second speed, the controller again collects the mechanical characteristic value of the pressure sensor to re-detect the diagonal eccentricity (DOOB) value. If the re-detected diagonal eccentricity (DOOB) value is less than the threshold set at the second speed, the controller controls the washing drum to increase to the third speed for spin-drying; if the re-detected diagonal eccentricity (DOOB) value exceeds the threshold set at the second speed, the controller controls the washing drum to maintain the second speed for spin-drying. In this embodiment, in order to prevent the OOB or DOOB value from increasing, especially rapidly, due to changes in load conditions during the speed increase after the eccentricity detection speed, and ultimately causing problems such as grinding, large vibration and high noise at higher speeds, an additional sensor-based eccentricity detection and judgment is added after the medium to high speed.
[0034] The washing drum will perform a shaking operation under the following conditions: When the washing drum is running at the first speed, the controller first performs a single eccentricity (OOB) detection on the washing drum. When the single eccentricity detection value is greater than the preset value set by OOB; When the washing drum is running at the first speed, the diagonal eccentricity (DOOB) value is detected by collecting the mechanical characteristic value of the pressure sensor. If the diagonal eccentricity (DOOB) value is greater than the threshold set at the first speed, then...
[0035] After the shake operation is completed, OOB and DOOB are re-detected in sequence.
[0036] If the eccentricity detection fails after N shake operations, a prompt message is generated to remind the user to manually shake the device.
[0037] In some technical solutions of this application's embodiments, the clothing handling equipment can be a washing machine, a washer-dryer combo, or a dryer. Compared to washing machines and washer-dryer combos with dehydration functions, dryers have relatively lower rotation speeds, resulting in a relatively lower probability of diagonal eccentricity (or even if diagonal eccentricity occurs, the amount of eccentricity is small due to the low rotation speed). Therefore, the control method of this application is applicable to washing machines and washer-dryer combos. Of course, in some models, the control method of this application can also be applied to dryers with only drying functions to improve the performance of the dryer.
[0038] In the technical solutions of this application embodiment, the sensor may include a displacement sensor, a velocity sensor, an acceleration sensor, or a pressure sensor. The data collected by the displacement sensor, velocity sensor, acceleration sensor, or pressure sensor can all be converted into a load exerted by the drive shaft on the bearing. In some embodiments, the mechanical characteristic value can be a pressure value or an acceleration value, which can directly reflect the intensity of the load exerted by the drive shaft on the bearing. Therefore, the sensor can be an acceleration sensor or a pressure sensor; of course, the parameters collected by the displacement sensor and velocity sensor can also be converted into pressure values or acceleration values through a built-in algorithm.
[0039] As an optional implementation of the above embodiments, such as Figure 5 As shown, before obtaining the mechanical characteristic value, the control method includes: S100, Obtain the maximum value among the mechanical values collected by the sensor; S200, determine the mechanical characteristic value based on the maximum value.
[0040] When diagonal eccentricity occurs inside the washing drum, the mechanical value collected changes with rotation due to the change in diagonal eccentricity and the position of the sensor. This change results in a maximum value. This maximum value reflects the intensity of the effect of the diagonal eccentricity on the sensor during rotation, and is therefore used to determine the mechanical characteristic value.
[0041] Combination Figure 6 As shown, taking a pressure sensor as an example, and with the sensor located on the left side of the drive shaft, simplifying the diagonal eccentricity to the drive shaft, the eccentricity rotates with the washing drum. When the eccentricity is at the top, the pressure detection value F of the force sensor is zero. As the eccentricity rotates counterclockwise with the washing drum, the eccentricity detection value F gradually increases. When the eccentricity rotates to the left position, the pressure detection value F reaches its maximum value F0. As the eccentricity continues to rotate counterclockwise, the pressure detection value F gradually decreases. When it rotates to the bottom, the pressure detection value F drops to zero. Then, when rotating from the bottom to the right, the eccentricity deviates to the right, while the pressure detection value remains 0. Based on this, when diagonal eccentricity occurs inside the washing drum, the eccentricity can be reflected by obtaining the maximum value in the pressure sensor. Therefore, the mechanical characteristic value is determined based on the maximum value.
[0042] In some embodiments, the maximum value can be used as the mechanical characteristic value. For example, when the washing drum rotates once, the sensor collects multiple mechanical values at a preset sampling frequency, these mechanical values are curve-fitted, and the maximum value is determined based on the curve, which is then used as the mechanical characteristic value. Alternatively, when the washing drum rotates once, the sensor collects multiple mechanical values at a preset sampling frequency, and the maximum value among these mechanical values is taken as the maximum value, which is then used as the mechanical characteristic value.
[0043] In some embodiments, multiple sensors can be used. The sensors are symmetrically distributed on the left and right sides of the drive shaft. For example, when the washing drum rotates once, two sensors collect multiple mechanical values at a preset sampling frequency. These mechanical values from the same sensor are then subjected to curve fitting, and the maximum value of the sensor is determined based on the curve. The mechanical characteristic value is then determined by averaging these two maximum values, improving accuracy. Alternatively, when the washing drum rotates once, two sensors collect multiple mechanical values at a preset sampling frequency. The maximum value among these mechanical values is taken as the maximum value, and this maximum value is used as the mechanical characteristic value; or the average of the maximum values collected by the two sensors is used as the mechanical characteristic value.
[0044] As an optional implementation of the above embodiments, obtaining the maximum value among the mechanical values collected by the sensor includes: The washing drum acquires a maximum value once every one or N rotations, so that multiple maximum values are acquired every M rotations of the washing drum; where M and N are integers, and M is an integer multiple of N; Determining the mechanical characteristic value based on the maximum value includes: The mechanical characteristic value is determined based on the plurality of maxima.
[0045] To eliminate fluctuations during the data collection process, a maximum value is acquired every one or N rotations of the washing drum, resulting in M or M / N maximum values. Multiple maximum values are acquired every M rotations of the washing drum. Based on these multiple maximum values, mechanical characteristic values are determined to eliminate errors caused by fluctuations and improve the accuracy of the mechanical characteristic values.
[0046] In an embodiment, the mechanical characteristic value can be obtained by averaging the multiple maxima, or the maximum value among the multiple maxima can be used as the mechanical characteristic value.
[0047] As an optional implementation of the above embodiments, the control method further includes: determining N based on the current rotational speed of the washing drum; wherein N is negatively correlated with the current rotational speed. In this embodiment, the higher the current rotational speed, the smaller the value of N; that is, the higher the rotational speed, the higher the frequency of maximum value acquisition, and the more maximum values can be obtained, which can improve the accuracy of diagonal eccentricity identification.
[0048] As an optional implementation of the above embodiments, the control method further includes: determining M based on the current rotational speed of the washing drum; wherein M is negatively correlated with the current rotational speed. In this embodiment, the higher the current rotational speed, the smaller the value of M; that is, the higher the rotational speed, the faster the maximum value is converted into a mechanical characteristic value, thereby quickly obtaining the diagonal eccentricity, so as to quickly determine whether the diagonal eccentricity of the washing drum exceeds the limit at the high rotational speed, thereby improving the safety of the laundry processing equipment and reducing the risk of drum collision.
[0049] As an optional implementation of the above embodiments, determining the diagonal eccentricity value of the washing drum based on the mechanical characteristic value includes: determining a mapping between the mechanical characteristic value and the diagonal eccentricity value based on the current rotational speed of the washing drum; and determining the diagonal eccentricity value based on the mechanical characteristic value and the mapping. In the embodiments, the effect of diagonal eccentricity on the sensor differs at different rotational speeds; therefore, in the embodiments of this application, there are different mapping relationships between the diagonal eccentricity value and the mechanical characteristic value at different rotational speeds.
[0050] For example, in some technical solutions of this application embodiment, a first mapping of mechanical characteristic value to diagonal eccentricity value at low speed and a second mapping of mechanical characteristic value to diagonal eccentricity value at high speed are provided. When the washing drum rotates at low speed, the diagonal eccentricity value is determined by the first mapping and the mechanical characteristic value, and then compared with a first threshold of DOOB at low speed to determine whether it can reach high speed. When the washing drum rotates at high speed, the diagonal eccentricity value is determined by the second mapping and the mechanical characteristic value, and then compared with a second threshold of DOOB at high speed to determine whether it can reach ultra-high speed or maintain the current high speed rotation.
[0051] In this embodiment, the mapping can be calibrated through experiments to determine the corresponding table or relationship curve.
[0052] For example, in some embodiments, a table showing the correspondence between the pressure value of the pressure sensor at low speeds and the diagonal eccentricity is provided:
[0053] When the measured pressure value is between two adjacent calibrated pressure values, the diagonal eccentricity can be obtained by interpolation.
[0054] For example, in some embodiments, a table showing the correspondence between the pressure values of the pressure sensor at high rotational speeds and the diagonal eccentricity is provided:
[0055] When the measured pressure value is between two adjacent calibrated pressure values, the diagonal eccentricity can be obtained by interpolation.

[0057] Before acquiring the mechanical characteristic value, the acquisition module 100 acquires the maximum value among the mechanical values collected by the sensor; The determining module 200 is used to determine the mechanical characteristic value based on the maximum value.
[0058] When the acquisition module 100 acquires the maximum value among the mechanical values collected by the sensor, it acquires the maximum value once every one or N rotations of the washing drum, so that multiple maximum values are acquired every M rotations of the washing drum; where M and N are integers, and M is an integer multiple of N; When determining the mechanical characteristic value based on the maximum value, module 200 determines the mechanical characteristic value based on the plurality of maximum values.
