[0001] The present application relates to the technical field of clothes processing equipment, and in particular to a control method of clothes processing equipment, an eccentricity control device and a readable storage medium. BACKGROUND

[0002] A washing machine is a common household clothes washing device. When the washing machine is performing a dehydration operation, an inner drum continuously accelerates rotation, clothes adhere to the inner drum wall to form an eccentric mass, the inner drum generates forced vibration under the excitation of the eccentric mass, the vibration is transmitted to an outer drum through a power input shaft, so that the entire inner and outer drums generate forced vibration, which further causes vibration of the entire washing machine, and even causes a phenomenon of barrel collision and displacement. This not only affects the service life of the washing machine parts, but also directly reduces the user experience due to the generated noise, and even harms the health of people. How to reduce the vibration and noise during the operation of the washing machine has always been a key to improving the quality and performance of the washing machine, especially with the development of high-speed and large-capacity washing machines, which makes it more complicated.

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0050] The exemplary embodiments of the present application provide a control method of a laundry treating apparatus, including: in response to determining that the laundry treating apparatus enters a spin-drying phase of a washing program, collecting a number of times that a vibration detection pulse is triggered in the spin-drying phase; comparing the collected number of times with a set number of times threshold, and issuing a correction instruction corresponding to the comparison result according to the comparison result. In the above-mentioned solution, by collecting the number of times that the vibration detection pulse is triggered after the laundry treating apparatus enters the spin-drying phase, then comparing the collected number of times with the set number of times threshold, and issuing the correction instruction corresponding to the comparison result according to the comparison result, the purposes of balancing eccentricity, reducing vibration and reducing noise are achieved.

[0051] It should be noted that the control method of the laundry treating apparatus provided by the exemplary embodiments of the present application can be run on a laundry treating apparatus such as a washing machine or a washer-dryer.

[0052] Figure 1 An architecture 100 suitable for implementing the control method of the laundry treating apparatus provided by the exemplary embodiments of the present application is shown. The architecture 100 includes a control unit 110 of a laundry treating apparatus, a sensor system 120, a counter 130 and a timer 140.

[0053] As Figure 1As shown, the control unit 110 is configured to receive and send control instructions in the course of the laundry treatment, and can also process data received from the sensor system 120 to determine corresponding correction instructions. The sensor system 120 is configured to detect the amount of vibration of the laundry treatment apparatus, and to send a signal that the vibration detection pulse is triggered when the detected amount of vibration exceeds a vibration amount threshold. The counter 130 is configured to count the number of times the vibration detection pulse is triggered. The timer 140 is configured to time the time of entry into the dehydration phase.

[0054] Figure 2 A flowchart of a control method 200 of a laundry treatment apparatus according to the first exemplary embodiment of the present application is shown.

[0055] As Figure 2 shown, the execution of the control method 200 of the laundry treatment apparatus includes the following steps:

[0056] S210, in response to determining that the laundry treatment apparatus enters the dehydration phase of the washing program, collecting the number of times the vibration detection pulse is triggered in the dehydration phase; and

[0057] S220, comparing the collected number with a set number threshold, and sending a correction instruction corresponding to the comparison result according to the comparison result.

[0058] It should be understood that the steps shown in the control method 200 of the laundry treatment apparatus are not exclusive, and the control method 200 of the laundry treatment apparatus can also include additional steps not shown and / or can omit the steps shown, and the scope of the present application is not limited in this respect. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. In addition, unless explicitly limited or contradictory to the context, the specific steps included in the methods described in the present application are not necessarily limited to the order described, but can be executed in any order or in parallel. The following steps S210 to S220 are described in detail with reference to Figure 1 and Figure 2

[0059] The washing program of the laundry treatment apparatus usually includes a main washing phase and a rinsing phase and a dehydration phase alternately performed after the completion of the main washing phase. When the laundry treatment apparatus is in the process performed in the rinsing phase, the washing drum has a preset rinsing rotation-to-stop ratio, and the drain assembly of the laundry treatment apparatus is in a closed state. When the laundry treatment apparatus is in the process performed in the dehydration phase, the washing drum has a preset dehydration rotation-to-stop ratio, and the drain assembly is in an open state.

[0060] ​It can be understood that the washing program of the laundry treating apparatus can also not include the main washing phase but only include the alternately performed rinsing phase and the dehydration phase; or the washing program of the laundry treating apparatus can also include a final dehydration phase performed after the alternately performed rinsing phase and the dehydration phase, and the washing drum also has a corresponding dehydration rotation-stop ratio when the laundry treating apparatus is in the final dehydration phase.

[0061] In step S210, when the control unit 110 of the laundry treating apparatus determines that the current laundry treating apparatus enters the dehydration phase of the washing program, the sensor system 120 is used to collect the number of times that the vibration detection pulse is triggered in the dehydration phase. It should be noted that the dehydration phase here can be the dehydration phase alternately performed with the rinsing phase, or the final dehydration phase, and the present application does not limit this.

[0062] Specifically, when the laundry treating apparatus is in the dehydration phase, the laundry treating apparatus vibrates due to the fast rotation speed of the washing drum. At this time, the sensor system 120 arranged on the laundry treating apparatus can detect the vibration amount of the laundry treating apparatus, and send a signal that the vibration detection pulse is triggered when the detected vibration amount exceeds the preset vibration amount threshold. It should be noted here that the sensor system 120 will not send a signal that the vibration detection pulse is triggered to the control unit 110 of the laundry treating apparatus when the detected vibration amount does not exceed the preset vibration amount threshold.

[0063] When the control unit 110 of the laundry treating apparatus receives the signal that the vibration detection pulse is triggered, the counter 130 is used to count the number of times that the received signal that the vibration detection pulse is triggered. The control unit 110 of the laundry treating apparatus has a corresponding number threshold value stored in advance, so in step S220, the control unit 110 can compare the number of times that the vibration detection pulse is triggered collected by the counter 130 with the number threshold value to determine whether the clothes in the washing drum of the laundry treating apparatus are eccentric, and send a correction instruction corresponding to the comparison result according to the comparison result, so as to achieve the purposes of balancing eccentricity, reducing vibration and reducing noise.

[0064] Figure 3 A flowchart of a control method 300 of a laundry treating apparatus according to a second exemplary embodiment of the present application is shown.

[0065] As shown in Figure 3 The execution of the control method 300 of the laundry treating apparatus includes the following steps:

[0066] S310, in response to determining that the laundry treating apparatus enters the dehydration phase, collecting the cumulative number of times that the vibration detection pulse is triggered within a first preset time range of the dehydration phase; and

[0067] S320, compare the collected cumulative number with a preset number threshold, and issue a correction instruction corresponding to the comparison result according to the comparison result.

[0068] It should be understood that the steps shown in the control method 300 of the laundry treating apparatus are not exclusive, and the control method 300 of the laundry treating apparatus can further include additional steps not shown and / or the shown steps can be omitted, and the scope of the present application is not limited in this respect.

[0069] Specifically, in step S310 of the present embodiment, when the control unit 110 of the laundry treating apparatus determines that the laundry treating apparatus enters the dehydration phase, the cumulative number of vibration detection pulses triggered within a first preset time range of the dehydration phase is collected by the counter 130, and then in step S320, the collected cumulative number is compared with a preset number threshold, and a correction instruction corresponding to the comparison result is issued according to the comparison result. In this way, it can be accurately and timely determined whether there is an eccentric condition in the washing drum of the laundry treating apparatus, and a correction instruction is timely issued when it is determined that there is an eccentric condition in the washing drum, thereby maintaining the balance of the laundry treating apparatus.

[0070] It should be noted that, as previously described herein, in the dehydration phase, the washing drum of the laundry treating apparatus has a corresponding rotation-to-stop ratio. In other words, in the dehydration phase, the washing drum has a plurality of alternating rotation timing and stop timing. The inventors have found through research that when the laundry treating apparatus does not have an eccentric condition in the first one to two rotation-to-stop timing in the dehydration phase, even when the laundry treating apparatus does not have an eccentric condition in the first rotation-to-stop timing, the probability of having an eccentric condition in the subsequent rotation-to-stop timing is small.

[0071] Based on this, as an example, the time of entering the dehydration phase is timed by the timer 140 to determine the above-mentioned first preset time range. The above-mentioned first preset time range is, for example, from the timing of entering the dehydration phase to the end of the second rotation-to-stop timing. Preferably, the above-mentioned first preset time range is from the timing of entering the dehydration phase to the end of the first rotation-to-stop timing. More preferably, the above-mentioned first preset time range is from the timing of entering the dehydration phase to one to two seconds after the start of the stop timing in the first rotation-to-stop timing.

[0072] In some embodiments, as shown in Figure 4 The step of issuing a correction instruction corresponding to the comparison result according to the comparison result in step S320 includes:

[0073] S321, in response to determining that the accumulated number of times is between the first number threshold and the second number threshold, obtaining an accumulated number of times of rinsing in the washing program of the clothes processing apparatus;

[0074] S322, in response to determining that the accumulated number of times of rinsing exceeds the third number threshold, issuing an instruction of eccentricity alarm; or, in response to determining that the accumulated number of times of rinsing does not exceed the third number threshold, issuing an instruction of pausing dehydration and re-entering the rinsing stage; and

[0075] S323, in response to determining that the accumulated number of times exceeds the second number threshold, issuing an instruction of eccentricity alarm.

[0076] Specifically, in step S321, when the control unit 110 of the clothes processing apparatus determines that the accumulated number of times x of the vibration detection pulse being triggered is between the first number threshold X1 and the second number threshold X2, it means that the degree of eccentricity in the washing drum is not serious, at this time, the control unit 110 of the clothes processing apparatus obtains the accumulated number of times y of rinsing in the washing program to determine the corresponding correction method.

[0077] In step S322, when the control unit 110 of the clothes processing apparatus determines that the accumulated number of times y of rinsing exceeds the third number threshold Y1, it means that the clothes in the washing drum have experienced enough rinsing process to be rinsed clean, in order to achieve the purpose of saving water, and also to prevent excessive processing process from damaging the clothes, at this time, the control unit 110 should issue an instruction of eccentricity alarm to remind the user to adjust the placement position of the clothes in the washing drum. However, when the control unit 110 of the clothes processing apparatus determines that the accumulated number of times y of rinsing does not exceed the third number threshold Y1, it means that the clothes in the washing drum have not been rinsed clean, at this time, the control unit 110 should issue an instruction of pausing dehydration and re-entering the rinsing stage, so that the position of the clothes in the washing drum can be changed by the rinsing process to achieve the purpose of correction.

[0078] In step S323, when the control unit 110 of the clothes processing apparatus determines that the accumulated number of times x of the vibration detection pulse being triggered collected by the counter 130 exceeds the second number threshold X2, it means that the degree of eccentricity in the washing drum is serious, and the possibility of achieving correction by the rinsing process is small, at this time, an instruction of eccentricity alarm is issued to remind the user to adjust the placement position of the clothes in the washing drum.

[0079] It should be noted that when the control unit 110 of the clothes processing apparatus determines that the accumulated number of times x of the vibration detection pulse being triggered collected by the counter 130 does not exceed the first number threshold X1, it means that there is no eccentricity condition in the washing drum within the first preset time range, at this time, the clothes processing apparatus can continue the dehydration process.

[0080] In some embodiments, as shown in FIG. 3, the step of issuing a deviation correction instruction corresponding to the comparison result in step S320 further comprises: Figure 5

[0081] S324, in response to determining that the cumulative number of times does not exceed the first number threshold, collecting a number of times that the vibration detection pulse is continuously triggered within a second preset time range of the dehydration phase;

[0082] S325, in response to determining that the collected number of times that the vibration detection pulse is continuously triggered exceeds the fourth number threshold, counting a number of times that the number of times that the vibration detection pulse is continuously triggered within the second preset time range exceeds the fourth number threshold; and

[0083] S326, in response to determining that the number of times that the number of times that the vibration detection pulse is continuously triggered within the second preset time range exceeds the fourth number threshold exceeds a fifth number threshold, issuing an instruction to issue an eccentricity alarm.

[0084] Specifically, as described herein before, when the laundry treating apparatus does not have an eccentricity condition within a time range of the previous one to two rotation stop sequences of the dehydration phase, even when the laundry treating apparatus does not have an eccentricity condition in the first rotation stop sequence, the probability of having an eccentricity condition in the subsequent rotation stop sequence is small. However, it is still possible to have an eccentricity condition in the subsequent rotation stop sequence, and it is still necessary to monitor the situation in which the vibration detection pulse is triggered in the subsequent rotation stop sequence. However, if the cumulative number of times that the vibration detection pulse is triggered in the rotation stop sequence is still analyzed to determine the deviation correction instruction, false positives can occur due to the user or other objects colliding with the laundry treating apparatus.

[0085] Based on this, in step S324 of the present embodiment, when the control unit 110 of the laundry treating apparatus determines that the cumulative number of times does not exceed the first number threshold within the first preset time range, the counter 130 is used to collect the number of times z that the vibration detection pulse is continuously triggered within a second preset time range of the dehydration phase. It should be noted here that the second preset time range described above is the remaining time of the dehydration phase after the first preset time range, and the timer 140 can be used to time the second preset time range.

[0086] ​In step S325, when the control unit 110 of the laundry treating apparatus determines that the number z of times that the vibration detection pulse is continuously triggered exceeds the fourth number threshold Z1, it means that there is an eccentricity condition in the washing drum of the laundry treating apparatus. At this time, the control unit 110 of the laundry treating apparatus controls the counter 130 to count the number s of times that the number z of times that the vibration detection pulse is continuously triggered exceeds the fourth number threshold Z1 within the second preset time range, so as to further determine the degree of eccentricity in the washing drum.

[0087] In step S326, when the control unit 110 of the laundry treating apparatus determines that the number s of times that the number z of times that the vibration detection pulse is continuously triggered exceeds the fourth number threshold Z1 exceeds the fifth number threshold S1, it means that the degree of eccentricity in the washing drum is relatively serious, and at this time, an eccentricity alarm instruction should be issued to remind the user to re-adjust the placement position of the laundry in the washing drum.

[0088] It should be noted that in step S325, when the control unit 110 of the laundry treating apparatus determines that the number z of times that the vibration detection pulse is continuously triggered does not exceed the fourth number threshold Z1, it means that there is no eccentricity condition in the washing drum, and at this time, the laundry treating apparatus can continue the dehydration process, and the eccentricity condition will not occur in the subsequent process of the dehydration stage.

[0089] The above scheme can avoid false alarm caused by the user or other objects colliding with the laundry treating apparatus by determining the eccentricity condition in the washing drum by using the number of times that the vibration detection pulse is continuously triggered within the second preset time range.

[0090] It should be noted that the first number threshold X1 currently set in the control unit 110 can be set by the laundry treating apparatus when it is shipped, or can be the correction threshold determined in the last drum self-cleaning program of the laundry treating apparatus, and the present application does not limit this.

[0091] Specifically, by collecting the number of times that the vibration detection pulse is triggered in the dehydration stage of the drum self-cleaning program after the laundry treating apparatus enters the drum self-cleaning program, and then comparing the collected number with the currently set correction threshold, the correction threshold of the laundry treating apparatus is determined, so that the correction threshold is a value that changes with the environment, which is equivalent to learning the threshold under the environmental conditions of the laundry treating apparatus, and the correction control of the laundry treating apparatus is more accurate.

[0092] The method for determining the first number threshold X1 through the last drum self-cleaning program of the laundry treating apparatus will be described in detail below.

[0093] To achieve the cleaning of dirt, bacteria and odor inside the drum assembly for the purpose of maintaining the hygiene and service life of the laundry treatment apparatus, most of the laundry treatment apparatuses on the market currently include a drum self-cleaning program. The drum self-cleaning program can clean the inside of the drum assembly by high-temperature water, detergent and mechanical operation. This helps to prevent bacterial growth and dirt accumulation, while also keeping the inside of the drum assembly clean and dry.

[0094] It should be noted that the laundry treatment apparatus does not place laundry to be washed or a small amount of laundry to be washed, such as a towel, inside the drum assembly when the drum self-cleaning program is running. Therefore, during the running of the drum self-cleaning program, vibration due to unbalanced position of laundry inside the drum does not occur.

[0095] In an exemplary application scenario, the drum self-cleaning program includes three spin-drying stages, namely spin-drying stage 1, spin-drying stage 2 and spin-drying stage 3. In the three spin-drying stages, the washing drum has a preset spin-to-stop ratio, and it can be understood that the spin-to-stop ratios in the three spin-drying stages can be the same or different, and the present application does not limit this. The control unit 110 of the laundry treatment apparatus stores a first number threshold X1 currently used to determine the eccentricity condition of the laundry treatment apparatus in the first preset time range of the spin-drying stage.

[0096] When the control unit 110 of the laundry treatment apparatus determines that the laundry treatment apparatus enters the drum self-cleaning program, the number of times x1 that the vibration detection pulse is triggered in the first preset time range of the spin-drying stage 1, the number of times x2 that the vibration detection pulse is triggered in the first preset time range of the spin-drying stage 2 and the number of times x3 that the vibration detection pulse is triggered in the first preset time range of the spin-drying stage 3 are collected by the counter 130, thereby collecting the cumulative number A1 of times that the vibration detection pulse is triggered in the first preset time range of each of the plurality of spin-drying stages, wherein A1 = x1 + x2 + x3. Then, based on the cumulative number A1, the average number D of times that the vibration detection pulse is triggered in the first preset time range of each of the plurality of spin-drying stages is determined, wherein D = A1 / 3.

[0097] The control unit 110 of the laundry treatment apparatus compares the collected average number D with the first number threshold X1. When the control unit 110 determines that the average number D is greater than the first number threshold X1, the first number threshold X1 used to determine the eccentricity condition of the laundry treatment apparatus in the first preset time range of the spin-drying stage is adjusted to the average number D. When the control unit 110 determines that the average number D is less than or equal to the first number threshold X1, the current first number threshold X1 used to determine the eccentricity condition of the laundry treatment apparatus in the first preset time range of the spin-drying stage is maintained unchanged.

[0098] The fourth number threshold Z1 currently set in the control unit 110 can be a number threshold set by the laundry treating apparatus at the time of manufacture, or can be a deviation correction threshold determined in the last drum self-cleaning program of the laundry treating apparatus, and the present application does not limit thereto.

[0099] The method of determining the fourth number threshold Z1 through the last drum self-cleaning program of the laundry treating apparatus will be described in detail below.

[0100] In this exemplary application scenario, the drum self-cleaning program includes three dewatering stages, namely, dewatering stage 1, dewatering stage 2, and dewatering stage 3. In these three dewatering stages, the washing drum has a preset rotation-to-stop ratio, and it can be understood that the rotation-to-stop ratios in these three dewatering stages can be the same or different, and the present application does not limit thereto. The control unit 110 of the laundry treating apparatus stores the fourth number threshold Z1 currently used to determine the eccentricity condition of the laundry treating apparatus in the second preset time range of the dewatering stage.

[0101] When the control unit 110 of the laundry treating apparatus determines that the laundry treating apparatus enters the drum self-cleaning program, the highest number y1 of vibration detection pulses continuously triggered in the second preset time range of the dewatering stage 1, the number y2 of vibration detection pulses continuously triggered in the second preset time range of the dewatering stage 2, and the highest number y3 of vibration detection pulses continuously triggered in the second preset time range of the dewatering stage 3 are collected by the counter 130, thereby collecting the cumulative number B1 of the highest number of vibration detection pulses continuously triggered in the second preset time range of each of the plurality of dewatering stages, wherein B1 = y1 + y2 + y3. Then, the average highest number Q of vibration detection pulses continuously triggered in the second preset time range in each of the plurality of dewatering stages is determined based on the cumulative number B1, wherein Q = B1 / 3.

[0102] The control unit 110 of the laundry treating apparatus compares the collected average highest number Q with the fourth number threshold Z1. When the control unit 110 determines that the average highest number Q is greater than the fourth number threshold Z1, the fourth number threshold Z1 used to determine the eccentricity condition of the laundry treating apparatus in the second preset time range of the dewatering stage is adjusted to the average highest number Q. When the control unit 110 determines that the average highest number Q is less than or equal to the fourth number threshold Z1, the fourth number threshold Z1 currently used to determine the eccentricity condition of the laundry treating apparatus in the second preset time range of the dewatering stage is maintained unchanged.

[0103] Figure 6 The structure of an eccentricity control device of a laundry treating apparatus according to an exemplary embodiment of the present application is shown.

[0104] As Figure 6As shown, the eccentricity control device 600 includes a vibration detection module 605, a processor 601 and a memory 602.
