[0080] When the existing washing machine is dehydrating, it mainly determines the eccentricity of the load in the washing tub by detecting the safety switch signal. However, it does not take into account that the eccentricity of the washing tub itself is not very large. Due to the influence of the eccentricity position, the washing tub may touch the safety switch, making the eccentricity of the load in the washing tub inaccurate, resulting in inaccurate control of the dehydration process, and thus low dehydration efficiency or failure to dehydrate normally;

[0081] The present invention creatively provides a method for determining the eccentricity type of a load in an inner drum, which is used in a clothing processing device. The clothing processing device includes an inner drum and a safety switch, wherein the safety switch is arranged on the outside of the inner drum and does not rotate with the inner drum; when the safety switch does not output a signal during the period when the inner drum rotates at a first preset speed for a first preset time, the eccentricity type of the load is determined to be small eccentricity; when the safety switch does not output a signal during the period when the inner drum rotates at a first preset speed for a second preset time, the eccentricity type of the load is determined to be medium eccentricity; when the safety switch outputs a signal during the period when the inner drum rotates at the first preset speed for a second preset time, the eccentricity type of the load is determined to be large eccentricity; the eccentricity type of the load in the inner drum can be accurately determined, and the dehydration speed can be accurately controlled, so that the clothing processing device can be dehydrated normally, while improving the dehydration efficiency and shortening the dehydration time.

[0082] It should be noted that the limitations on the eccentric positions "A", "B", "C" and "D" in the present application do not have specific meanings, but are only for the convenience of distinguishing and expressing different eccentric positions.

[0083] Example 1

[0084] <Determination method>

[0085] The present embodiment provides a method for determining the eccentricity type of a load in an inner drum, which is used in a clothes processing device, wherein the clothes processing device includes an inner drum; the eccentricity type of the load includes at least small eccentricity, medium eccentricity and large eccentricity with increasing eccentricity degrees in sequence; a safety switch that does not rotate with the inner drum is provided on the outer side of the inner drum, and the safety switch is used to detect the eccentricity degree of the load; a plurality of eccentric positions are provided on the outer wall of the inner drum, and during the rotation of the inner drum, each eccentric position may collide with the safety switch, and then the safety switch may output a signal;

[0086] like Figure 1 As shown, taking the outer wall of the inner cylinder with four eccentric positions as an example, along the circumference of the inner cylinder, the outer wall of the inner cylinder is sequentially provided with eccentric position A, eccentric position B, eccentric position C and eccentric position D;

[0087] During the rotation of the inner drum, the probability of the eccentric positions A, B, C and D touching the safety switch is different; when the eccentricity of the load in the inner drum is small, the output signal of the safety switch is detected, and then it is misjudged as large eccentricity, and the dehydration process is stopped; or when the eccentricity of the load in the inner drum is large, the output signal of the safety switch is not detected, and then it is misjudged as small eccentricity, and the speed of the inner drum is continued to be controlled, resulting in the overall displacement of the clothing processing device;

[0088] In addition, similar problems may occur when the installation ground of the clothes treating apparatus is inclined.

[0089] In this embodiment, when the clothes processing device is dehydrating, the inner drum is controlled to rotate at a low speed for a certain period of time, and the eccentricity type of the load in the inner drum is accurately determined by recording whether the safety switch outputs a signal during this period; the problem of inaccurate determination of the eccentricity type of the load in the inner drum caused by the eccentric position of the inner drum and the inclination of the ground is overcome. When the eccentricity type of the load in the inner drum is small eccentricity, the rotation speed of the inner drum is increased, thereby improving the dehydration efficiency; when the eccentricity type of the load in the inner drum is large eccentricity, the dehydration is stopped, thereby avoiding the problem of the overall displacement of the clothes processing device caused by the excessive rotation speed of the inner drum;

[0094] Step P2 includes the following two implementation modes:

[0095] The first implementation mode is: 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 period when the inner drum rotates at a first preset speed for a first preset time, it is determined that the eccentricity type of the load is small eccentricity;

[0099] P214, when the safety switch does not output a signal during the period when the inner drum rotates at the first preset speed for the second preset time, it is determined that the eccentricity type of the load is medium eccentricity;

[0100] P215, when the safety switch outputs a signal during the period when the inner drum rotates at the first preset speed for the second preset time, it is determined that the eccentricity type of the load is large eccentricity;

[0101] Among them, the difference between the first preset time length and the second preset time length is within the preset time length range, the first preset speed is n1, and n1 satisfies: 60r / min≤n1≤90r / min; the first preset time length is T1 and the second preset time length is T2, and T1 and T2 satisfy: 5s≤T1≤15s, 5s≤T2≤15s.

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

[0103] P221, when the safety switch does not output a signal during the period when the inner drum rotates at a first preset speed for a first preset time, determining that the eccentricity type of the load is small eccentricity;

[0104] P222, when the safety switch first outputs a signal and then does not output a signal during the period when the inner drum rotates at a first preset speed for a first preset time, it is determined that the eccentricity type of the load is medium eccentricity;

[0105] P223. When the safety switch continuously outputs a signal during the period when the inner drum rotates at a first preset speed for a first preset time period, it is determined that the eccentricity type of the load is large eccentricity.

[0157] Example 3

[0158] Different from Examples 1 and 2, Figure 4 As shown, this embodiment proposes to classify the eccentricity types of the inner cylinder into three categories:

[0159] The first eccentric type is small eccentricity, and the inner drum will not hit the safety switch when the dehydration starts;

[0160] The second eccentricity type is medium eccentricity. When the dehydration process is started, the inner drum has a probability of hitting the safety switch. However, when the dehydration process is started under this eccentricity type, the inner drum can increase speed normally.

[0161] The third eccentricity type is a large eccentricity. When the dehydration process is started under this eccentricity type, the clothing processing device cannot dehydrate normally or the entire machine may be displaced and have other safety hazards during the dehydration process.

[0162] The clothes processing device starts the load eccentricity type determination process and enters step Y1;

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

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

[0165] If the safety switch does not output a signal, it is determined that the eccentricity type of the load in the inner cylinder is small eccentricity; go to step Y5;

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

[0167] Step Y2 can accurately determine the eccentricity type of the load in the inner drum; in step Y6, during the period when the inner drum speed increases to the second preset speed n2 and during the period when the second preset speed n2 is maintained, it is not detected whether the safety switch outputs a signal, ensuring that the load in the inner drum can be dehydrated normally, and the eccentricity type of the load will not be misjudged due to the accidental touch of the safety switch, thereby stopping the dehydration process;

[0168] Step Y3: Control the inner drum to maintain the rotation of the first preset speed n1 for 5s to 15s; during the period when the inner drum maintains the rotation of the first preset speed n1, record whether the safety switch outputs a signal;

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

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

[0171] Step Y3 can identify the large eccentricity of the load in the inner cylinder to avoid the displacement of the whole machine caused by the large eccentricity speed increase;

[0172] Step Y4: When the eccentricity type of the load in the inner drum is large eccentricity, controlling the clothes processing device to stop the dehydration process;

[0173] Step Y5: When the eccentricity type of the load in the inner drum is small eccentricity, the current load eccentricity type determination process is stopped; the clothes processing device is controlled to execute the dehydration process again, and the process goes to step Y6;

[0174] Step Y6: Control the clothes processing device to execute the dehydration process, control the inner drum to increase the speed to the second preset speed n2, maintain the time for 5s to 15s, 100r / min≤n2≤160r / min is optimal; during the second preset speed n2, shield the output signal of the safety switch; control the inner drum to continue to increase the speed according to the set dehydration process, increase the speed to the target speed and maintain the target speed to complete the dehydration process; record whether the safety switch outputs a signal during the inner drum speed increase process;

[0175] ① If the safety switch outputs a signal, the clothing processing equipment is controlled to stop the dehydration process;

[0176] ② If the safety switch does not output a signal, the clothing processing equipment is controlled to continue the dehydration process;

[0177] Step Y7: When the eccentricity type of the load in the inner drum is medium eccentricity, the current load eccentricity type determination process is stopped; the clothes processing device is controlled to execute the dehydration process again, and the process goes to step S8;

[0178] Step Y8: Control the clothes processing device to execute the dehydration process, control the inner drum to increase the speed to the second preset speed n2, maintain the speed for 5s to 15s, and record whether the safety switch outputs a signal during the inner drum speed increase process; 100r / min≤n2≤160r / min is optimal;

[0179] ① If the safety switch does not output a signal, the clothes processing equipment is controlled to execute a normal speed-up process, and the speed of the inner drum is controlled to increase to the target speed and the target speed is maintained to complete the dehydration process; during the speed-up process of the inner drum, whether the safety switch outputs a signal is recorded, and if the safety switch outputs a signal, the clothes processing equipment is controlled to stop the dehydration process; if the safety switch does not output a signal, the speed of the inner drum is controlled to increase to the target speed and the target speed is maintained to complete the dehydration process;

[0180] ② If the safety switch outputs a signal, the inner drum is controlled to maintain the second preset speed n2 for 5s to 15s; then the inner drum is controlled to maintain the second preset speed n2 for 5s to 15s;

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

[0182] ③If the safety switch outputs a signal, the clothing processing equipment is controlled to stop the dehydration process;

[0183] ④ If the safety switch does not output a signal, the clothing processing equipment is controlled to execute a normal speed-up process, and whether the safety switch outputs a signal during the inner drum speed-up process is recorded; if the safety switch outputs a signal, the clothing processing equipment is controlled to stop the dehydration process; if the safety switch does not output a signal, the clothing processing equipment is controlled to continue the dehydration process.

[0184] Steps Y2 and Y3 can accurately distinguish the large eccentric load and the small eccentric load in the inner cylinder; they cannot accurately determine the medium eccentric load in the inner cylinder;

[0185] Before executing step Y8, the eccentricity type of the load in the inner cylinder must be determined by steps Y2 and Y3. Step S8 can only be executed when the eccentricity type of the load is medium eccentricity or small eccentricity, because when the eccentricity type of the load is large eccentricity, the inner cylinder in step Y8 will hit the box when it rotates at the second preset speed n2;

[0186] Step Y8 further divides the eccentric load determined in step Y3 into two parts; one part of the eccentricity type of the load in the inner drum meets the dehydration requirements, and the other part of the eccentricity type of the load in the inner drum does not meet the dehydration requirements; therefore, through steps Y2, Y3 and Y8, the eccentricity type of the load in the inner drum can be accurately determined, and the dehydration process will continue if it meets the dehydration requirements, and the dehydration process will be stopped if it does not meet the dehydration requirements.
