[0080] The existing washing machine mainly detects the safety switch signal to judge the eccentricity of the load in the washing tub during dehydration. However, it does not consider that the eccentricity of the washing tub itself is not very large, and the washing tub may touch the safety switch due to the influence of the position of the eccentricity, so that the eccentricity of the load in the washing tub is not accurately judged, which leads to inaccurate control of the dehydration process, and further low dehydration efficiency or normal dehydration.

[0081] The present application creatively provides a method for determining the eccentric type of the load in the inner tub, which is used in a clothes processing device, and the clothes processing device comprises an inner tub and a safety switch, wherein the safety switch is arranged on the outer side of the inner tub and does not rotate with the inner tub; when the safety switch does not output a signal during the first preset time period when the inner tub rotates at a first preset rotating speed, it is determined that the eccentric type of the load is small eccentricity; when the safety switch does not output a signal during the second preset time period when the inner tub rotates at the first preset rotating speed, it is determined that the eccentric type of the load is medium eccentricity; when the safety switch outputs a signal during the second preset time period when the inner tub rotates at the first preset rotating speed, it is determined that the eccentric type of the load is large eccentricity; the eccentric type of the load in the inner tub can be accurately determined, and then the dehydration speed can be accurately controlled, so that the clothes processing device can be normally dehydrated, and the dehydration efficiency is improved and the dehydration time is shortened.

[0082] It should be noted that the application is limited to the eccentric positions "A", "B", "C" and "D", which do not have specific meanings, but are only used for distinguishing and expressing different eccentric positions.

[0083] Example 1

[0084] <Method for determining>

[0085] This embodiment provides a method for determining the eccentricity type of the load inside the inner drum, used in a garment processing device. The garment processing device includes an inner drum. The eccentricity type of the load includes at least small eccentricity, medium eccentricity, and large eccentricity, with the degree of eccentricity increasing sequentially. A safety switch that does not rotate with the inner drum is provided on the outer side of the inner drum. The safety switch is used to detect the degree of eccentricity of the load. The outer wall of the inner drum has multiple eccentricity positions. During the rotation of the inner drum, each eccentricity position may collide with the safety switch, and the safety switch can output a signal.

[0086] like Figure 1 As shown, taking the example of four eccentric positions on the outer wall of the inner cylinder, along the circumference of the inner cylinder, the outer wall of the inner cylinder is provided with eccentric position A, eccentric position B, eccentric position C and eccentric position D in sequence.

[0087] During the rotation of the inner drum, the probability of the safety switch being triggered at eccentric positions A, B, C, and D is different. There may be issues where, when the load eccentricity inside the inner drum is small, the output signal of the safety switch is detected, leading to a misjudgment as a large eccentricity and thus stopping the spin-drying process; or when the load eccentricity inside the inner drum is large, no output signal of the safety switch is detected, leading to a misjudgment as a small eccentricity and thus continuing to control the inner drum speed, causing the overall displacement of the garment processing equipment.

[0088] In addition, similar problems can occur when the ground on which the garment processing equipment is installed is tilted.

[0089] In this embodiment, during the dehydration process of the garment processing equipment, the inner drum is controlled to rotate at a low speed for a certain period of time. By recording whether the safety switch outputs a signal during this period, the eccentricity type of the load inside the inner drum can be accurately determined. This overcomes the problem that the eccentricity type of the load inside the inner drum is not accurately determined due to the eccentric position of the inner drum and the inclination of the ground. When the eccentricity type of the load inside the inner drum is small, the rotation speed of the inner drum is increased, thereby improving the dehydration efficiency. When the eccentricity type of the load inside the inner drum is large, the dehydration is stopped to avoid the problem of the entire garment processing equipment shifting due to excessive rotation speed of the inner drum.

[0090] Specifically, such as Figure 2 As shown, the determination method includes:

[0091] P1. Control the inner cylinder to rotate at a first preset speed for a first preset duration;

[0092] P2. Determine the type of load eccentricity based on the signal output of the safety switch during the first preset rotation speed and first preset duration of the inner cylinder.

[0093] The signal output status of the safety switch includes whether the safety switch outputs a signal and / or the duration of the output signal.

[0094] Step P2 includes the following two implementation methods;

[0095] The first implementation is that the signal output condition of the safety switch includes whether the safety switch outputs a signal; P2 includes:

[0096] P211, when the safety switch does not output a signal during the first preset duration that the inner cylinder rotates at the first preset rotating speed, determining that the eccentric type of the load is small eccentricity;

[0097] P212, when the safety switch outputs a signal during the first preset duration that the inner cylinder rotates at the first preset rotating speed, continuing to control the inner cylinder to rotate at the first preset rotating speed for a second preset duration;

[0098] P213, recording whether the safety switch outputs a signal during the second preset duration that the inner cylinder rotates at the first preset rotating speed;

[0099] P214, when the safety switch does not output a signal during the second preset duration that the inner cylinder rotates at the first preset rotating speed, determining that the eccentric type of the load is medium eccentricity;

[0100] P215, when the safety switch outputs a signal during the second preset duration that the inner cylinder rotates at the first preset rotating speed, determining that the eccentric type of the load is large eccentricity;

[0101] Wherein, the difference between the first preset duration and the second preset duration is within a preset duration interval, the first preset rotating speed is n1, and n1 satisfies: 60r / min≤n1≤90r / min; the first preset duration is T1 and the second preset duration is T2, and T1 and T2 satisfy: 5s≤T1≤15s, 5s≤T2≤15s.

[0102] The second implementation is that the signal output condition of the safety switch includes whether the safety switch outputs a signal and the duration of the signal output by the safety switch; P2 includes:

[0103] P221, when the safety switch does not output a signal during the first preset duration that the inner cylinder rotates at the first preset rotating speed, determining that the eccentric type of the load is small eccentricity;

[0104] P222, when the safety switch outputs a signal first and then does not output a signal during the first preset duration that the inner cylinder rotates at the first preset rotating speed, determining that the eccentric type of the load is medium eccentricity;

[0105] P223, when the safety switch always outputs a signal during the first preset duration that the inner cylinder rotates at the first preset rotating speed, determining that the eccentric type of the load is large eccentricity.

[0149] In steps W31 and W33, controlling the clothes treatment apparatus to run the dehydration program or stop running the dehydration program comprises:

[0150] W341, control the rotating speed of the inner drum to increase from the first preset rotating speed to a second preset rotating speed, and rotate the inner drum at the second preset rotating speed for a third preset duration; during the third preset duration of the inner drum rotating at the second preset rotating speed, shield the signal of the safety switch;

[0157] Example 3

[0158] Unlike Examples 1 and 2, as Figure 4 As shown in this embodiment, the eccentricity type of the inner cylinder is divided into three categories:

[0159] The first type of eccentricity is small eccentricity, which prevents the inner drum from hitting the safety switch when the dehydration starts.

[0160] The second type of eccentricity is medium eccentricity. When the dehydration process starts, the inner drum may hit the safety switch. However, when the dehydration process is started under this type of eccentricity, the inner drum can accelerate normally.

[0161] The third type of eccentricity is large eccentricity. When the dehydration process is started under this type of eccentricity, the clothing processing equipment cannot dehydrate normally or there is displacement of the whole machine and other safety hazards during the dehydration process.

[0162] The garment processing equipment initiates the load eccentricity type determination process and proceeds to step Y1;

[0163] Step Y1: Control the inner cylinder to maintain the first preset rotation speed n1 for a duration of 5s to 15s; specifically, 60r / min≤n1≤90r / min is optimal; proceed to step Y2;

[0164] Step Y2: While the inner cylinder is rotating at the first preset speed n1, record whether the safety switch outputs a signal;

[0165] If the safety switch does not output a signal, the eccentricity type of the load inside the inner cylinder is determined to be small eccentricity; proceed to step Y5.

[0166] If the safety switch outputs a signal, proceed to step Y3;

[0167] The step Y2 can accurately determine the eccentric type of the load in the inner cylinder; in the step Y6, the safety switch is not detected during the period when the inner cylinder is accelerated to the second preset rotating speed n2 and the period when the inner cylinder is maintained at the second preset rotating speed n2, so that the load in the inner cylinder can be normally dewatered, and the eccentric type of the load is not misjudged due to the false touch of the safety switch, and then the dewatering process is stopped;

[0168] Step Y3: the inner cylinder is controlled to be maintained at the first preset rotating speed n1, and the maintaining time is 5s to 15s; whether the safety switch outputs a signal is recorded during the period when the inner cylinder is maintained at the first preset rotating speed n1;

[0169] If the safety switch does not output a signal, it is determined that the eccentric type of the load in the inner cylinder is medium eccentricity; and the step Y7 is entered;

[0170] If the safety switch outputs a signal, it is determined that the eccentric type of the load in the inner cylinder is large eccentricity; and the step Y4 is entered;

[0171] The step Y3 can identify the large eccentricity of the load in the inner cylinder, so that the displacement of the whole machine caused by the acceleration of the large eccentricity is avoided;

[0172] Step Y4: when the eccentric type of the load in the inner cylinder is large eccentricity, the clothes treatment equipment is controlled to stop the dewatering process;

[0173] Step Y5: when the eccentric type of the load in the inner cylinder is small eccentricity, the determination process of the current load eccentric type is stopped; the clothes treatment equipment is controlled to execute the dewatering process again, and the step Y6 is entered;

[0174] Step Y6: the clothes treatment equipment is controlled to execute the dewatering process, the inner cylinder is accelerated to the second preset rotating speed n2, and the maintaining time is 5s to 15s, 100r / min≤n2≤160r / min is optimal; the output signal of the safety switch is shielded during the period when the inner cylinder is maintained at the second preset rotating speed n2; the inner cylinder is controlled to continue to accelerate according to the set dewatering process, to accelerate to a target rotating speed and maintain the target rotating speed to complete the dewatering process; whether the safety switch outputs a signal is recorded during the acceleration process of the inner cylinder;

[0175] If the safety switch outputs a signal, the clothes treatment equipment is controlled to stop the dewatering process;

[0176] If the safety switch does not output a signal, the clothes treatment equipment is controlled to continue to execute the dewatering process;

[0177] Step Y7: when the eccentric type of the load in the inner cylinder is medium eccentricity, the determination process of the current load eccentric type is stopped; the clothes treatment equipment is controlled to execute the dewatering process again, and the step S8 is entered;

[0178] Step Y8: controlling the laundry treatment apparatus to perform a dewatering course, controlling the inner tub to accelerate to a second preset rotational speed n2, maintaining for a time duration of 5s to 15s, recording whether the safety switch outputs a signal during the acceleration of the inner tub; 100r / min≤n2≤160r / min is optimal;

[0179] ①If the safety switch does not output a signal, controlling the laundry treatment apparatus to perform a normal acceleration course, controlling the inner tub to accelerate to a target rotational speed and maintaining the target rotational speed to complete the dewatering course; recording whether the safety switch outputs a signal during the acceleration of the inner tub, if the safety switch outputs a signal, controlling the laundry treatment apparatus to stop the dewatering course; if the safety switch does not output a signal, controlling the inner tub to accelerate to the target rotational speed and maintaining the target rotational speed to complete the dewatering course;

[0180] ②If the safety switch outputs a signal, controlling the inner tub to maintain the second preset rotational speed n2 for a time duration of 5s to 15s, and then controlling the inner tub to maintain the second preset rotational speed n2 for a time duration of 5s to 15s again;

[0181] During the two times of maintaining the second preset rotational speed n2, recording whether the safety switch outputs a signal;

[0182] ③If the safety switch outputs a signal, controlling the laundry treatment apparatus to stop the dewatering course;

[0183] ④If the safety switch does not output a signal, controlling the laundry treatment apparatus to perform a normal acceleration course, recording whether the safety switch outputs a signal during the acceleration of the inner tub; if the safety switch outputs a signal, controlling the laundry treatment apparatus to stop the dewatering course; if the safety switch does not output a signal, controlling the laundry treatment apparatus to continue to perform the dewatering course.

[0184] Steps Y2 and Y3 can accurately distinguish between large eccentric load and small eccentric load in the inner tub; it is not possible to accurately determine the medium eccentric load in the inner tub;

[0185] Before performing step Y8, the determination of the eccentric type of the load in the inner tub performed by steps Y2 and Y3 is necessary, only when the eccentric type of the load is medium eccentric and small eccentric, step S8 can be performed, because when the inner tub rotates at the second preset rotational speed n2 in step Y8, it will hit the cabinet when the eccentric type of the load is large eccentric;

[0186] Step Y8 further divides the medium eccentric load determined in step Y3 into two parts; one part of the eccentric type of the load in the inner tub meets the dewatering requirement, and the other part of the eccentric type of the load in the inner tub does not meet the dewatering requirement; therefore, through steps Y2, Y3 and Y8, the eccentric type of the load in the inner tub can be accurately determined, the dewatering course is continued to be performed if it meets the dewatering requirement, and the dewatering course is stopped if it does not meet the dewatering requirement.
