[0022] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions.

[0023] It should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "first", "second" are only for description purposes, and cannot be understood as indicating or implying relative importance.

[0024] In order to solve the problem that the existing washing machine cannot achieve good laundry treatment effect due to the inability to classify the size of the laundry, the present application provides a control method of a laundry treatment apparatus, wherein the specific form of the laundry treatment apparatus of the present application includes various forms, for example, it can be a washing machine or a washing-drying integrated machine, etc. In order to facilitate description, the laundry treatment apparatus of the present application will be introduced as a washing machine, specifically, as shown in Figure 1 The control method of the present application includes the following steps:

[0025] Step S100: after entering the washing function, control the water inlet function to start.

[0026] Preferably, after entering the washing function, the weight of the laundry can be obtained first, and when the weight of the laundry is less than the preset weight, it indicates that the laundry put into the washing machine is a small amount of laundry, and then the classification of the small amount of laundry can be further divided based on the following steps to determine the size classification of the laundry, so as to improve the accuracy of determining the size classification of the laundry. After the weight judgment of the laundry is completed, the water inlet function is controlled to start to water the washing tub. The above-mentioned preset weight can be obtained based on empirical value, or obtained based on experiment, etc. In addition, the way of entering the washing function includes various ways, for example, after the user selects the start function button, the washing function is entered, or after the user sends the washing function instruction to the washing machine through the terminal such as mobile phone APP, the washing function is entered, etc.

[0027] In addition, the method for obtaining the weight of the laundry includes various methods, for example, a weighing sensor is arranged at the bottom of the washing tub of the washing machine, the weight of the laundry is obtained through the weighing sensor, or the laundry is roughly weighed through the rotation of the impeller, and then the weight of the laundry is reflected through the power of the motor driving the rotation of the impeller. Of course, whether the laundry in the washing machine is a small amount of laundry can also be determined in other ways, for example, it can be determined through the user-selected washing parameter value, for example, when the user-selected water level value is less than the preset water level value, it is determined that the laundry is a small amount of laundry, or a washing button for a small amount of laundry is specially designed on the washing machine, and after the user presses the button, it is considered that the laundry in the washing machine is a small amount of laundry, and then the classification of the small amount of laundry can be further identified based on the steps below.

[0028] Step S200: when the water reaches the preset water level, the water inlet function is controlled to be closed.

[0029] Firstly, the output mode of the motor driving the rotation of the impeller is introduced, wherein the output mode of the motor of the present application is divided into three kinds, which are strong output mode, standard output mode and weak output mode, various output modes can be characterized by the rotation stop ratio of the motor, for example, the strong output mode corresponds to the first preset rotation stop ratio, the standard output mode corresponds to the preset washing rotation stop ratio set in the washing program, and the weak output mode corresponds to the second preset rotation stop ratio, and the first preset rotation stop ratio is greater than the preset washing rotation stop ratio, and the preset washing rotation stop ratio is greater than the second preset rotation stop ratio, for example, the first preset rotation stop ratio is 1.6 / 0.8, the preset washing rotation stop ratio is 1.2 / 0.8, and the second preset rotation stop ratio is 0.8 / 0.8, so as to control the intensity of the water flow according to the different rotation stop ratios, specifically, the water flow intensity when the motor runs in the strong output mode is greater than the water flow intensity when the motor runs in the standard output mode, and the water flow intensity when the motor runs in the standard output mode is greater than the water flow intensity when the motor runs in the weak output mode. Of course, although various output modes of the present application are introduced by the rotation stop ratio of the motor, this does not intend to limit the protection scope of the present application, for example, the rotation speed of the motor can also be used to characterize the output mode, that is, the strong output mode corresponds to the first preset rotation speed, the standard output mode corresponds to the preset washing rotation speed, and the weak output mode corresponds to the second preset rotation speed, wherein the first preset rotation speed is greater than the preset washing rotation speed, and the preset washing rotation speed is greater than the second preset rotation speed.

[0030] Preferably, when the water level reaches the preset water level for the first time, the water inlet function is controlled to be closed, and the motor driving the rotation of the impeller of the washing machine is controlled to run in a weak output mode to obtain a weak water flow intensity to stir the clothes, so that the clothes can be fully soaked and energy can be saved. When a preset time is reached, it is determined that the clothes have been completely soaked, at which time the water level of the washing machine will decrease. In this case, the water inlet function is controlled to be enabled again to supplement water. When the water inlet reaches the preset water level again, since the clothes have been completely soaked, the water level will not decrease at this time, and the water inlet function is controlled to be closed.

[0031] It can be understood that, although the present application is introduced above by twice water inlet to the preset water level, this is not intended to limit the protection scope of the present application. For example, the first water inlet can be above the preset water level, and after the clothes are completely soaked, it is determined whether to supplement water or drain water, etc.

[0032] Step S300: controlling the motor driving the rotation of the impeller of the clothes processing device to run in a strong output mode.

[0033] When the water inlet reaches the preset water level, as above after the water supplement, the motor driving the rotation of the impeller of the washing machine is controlled to run in a strong output mode to obtain a strong water flow intensity.

[0034] Step S400: obtaining a motor parameter.

[0035] Preferably, the motor parameter is the motor power, and of course other parameters such as motor current can also be replaced. In order to facilitate the introduction, the motor parameter of the present application will be introduced below as an example of the motor power.

[0036] Step S500: determining the size classification of the clothes based on the range in which the motor parameter is located.

[0037] Preferably, when the motor power is greater than or equal to a preset power, the clothes are determined to be large clothes, and when the motor power is less than the preset power, the clothes are determined to be multiple small clothes.

[0038] The applicant finds that when the motor driving the pulsator of the washing machine is running in a high output mode, i.e. the water flow in the washing machine is increased by the agitation of the pulsator, washing a large piece of clothing will cause eccentricity, while washing multiple small pieces of clothing will not easily cause eccentricity. For example, when the water flow is strong, washing a bed sheet will cause eccentricity, while washing ten pairs of socks will not cause eccentricity. When a large piece of clothing is eccentric, the power of the motor driving the rotation of the pulsator will increase. Based on this finding, the present application determines that the clothing is a large piece of clothing when the motor power is greater than or equal to a preset power, and determines that the clothing is multiple small pieces of clothing when the motor power is less than the preset power, so that the classification of the clothing can be accurately divided. The above-mentioned preset power can be obtained based on experiments, or obtained based on empirical formula, etc. It can be understood that although the present application is introduced as determining that the clothing is multiple small pieces of clothing when the motor power is less than the preset power, the present application is also applicable to determining that the clothing is a single small piece of clothing, etc.

[0039] After determining the size classification of the clothing, the motor driving the rotation of the pulsator of the washing machine is controlled to run in a standard output mode, i.e. the motor is controlled to run in a preset washing rotation-to-stop ratio, so as to obtain a standard washing water flow intensity to wash the clothing, until the washing function is exited after the washing is completed.

[0040] Step S600: based on the size classification of the clothing, an optimized clothing processing mode is executed.

[0041] Possibly, when the clothing is determined to be a large piece of clothing, and when the dehydration function is running, the program setting initial rotation speed is reduced, and the program setting time to rise to the program setting final rotation speed is extended. It can be understood that the program setting initial rotation speed, the program setting final rotation speed and the program setting time are all preset, and the relationship between the three can be determined by a formula to control the normal dehydration program. By reducing the program setting initial rotation speed and extending the program setting time to rise to the program setting final rotation speed, the present application can avoid the eccentricity of the large piece of clothing at the initial dehydration, improve the service life of the washing machine, and improve the user experience. Further, when it is determined to be multiple small pieces of clothing, the dehydration function can be executed based on the program setting initial rotation speed, the program setting final rotation speed and the program setting time. This control method can perform targeted dehydration control on large pieces of clothing, multiple small pieces of clothing, etc., and improve the user experience.

[0042] Possibly, when the garments are identified as multiple small items, the shaking function is activated after the spin-drying cycle. Because there are many small garments, they are prone to sticking to the sides after spin-drying. Therefore, this invention adds a shaking function after spin-drying to prevent this phenomenon, thus providing convenience for the user to remove the garments. It is understood that the shaking function can be implemented by controlling the motor driving the impeller to operate at a set rotation-to-stop ratio. Preferably, it can operate at the second preset rotation-to-stop ratio described above, effectively preventing multiple small garments from sticking to the sides while saving energy.

[0043] The aforementioned control method enables the washing machine to perform targeted optimized garment processing modes for large garments and multiple small garments respectively. Specifically, by controlling the spin-drying process of large garments, it avoids the occurrence of eccentricity, and by adding a shaking function after spin-drying multiple small garments, it avoids the phenomenon of sticking to the wall. Compared with the prior art where all garments of different sizes are processed with the same program, this invention can execute corresponding programs based on the different categories of garments of different sizes, avoiding phenomena such as eccentricity or sticking to the wall, and has strong versatility and practicality.

[0044] The following describes a possible, more specific implementation of the control method for the garment processing equipment of the present invention.

[0045] like Figure 2 and Figure 3 As shown ( Figure 2 and Figure 3 An implementation method that can be combined into a whole includes the following steps:

[0048] Step S703: Determine if the weight of the clothing is less than the preset weight. If yes, proceed to step S704; otherwise, proceed to step S702.

[0049] Step S704: Enable water inlet control function.

[0050] Step S705: When the water level first reaches the preset level, the water inlet function is turned off.

[0051] Step S706: Control the motor to operate in a low output mode.

[0052] Step S707: Determine if a preset time has elapsed. If yes, proceed to step S708; otherwise, return to step S706.

[0053] Step S708: control the water inlet function to be enabled again.

[0054] Step S709: when the water inlet reaches the preset water level again, control the water inlet function to be closed.

[0055] Step S710: control the motor to run in a strong output mode.

[0056] Step S711: obtain the motor power.

[0057] Step S712: determine whether the motor power is greater than or equal to a preset power, if yes, execute step S713, if not, execute step S714.

[0058] Step S713: determine that the clothes are large clothes, then execute step S715, and execute step S719 when the spinning function is running.

[0059] Step S714: determine that the clothes are multiple small clothes, then execute step S715, and execute step S718 after the spinning function is ended.

[0060] Step S715: control the motor to run in a weak output mode.

[0061] Step S716: determine whether the washing is ended, if yes, execute step S717, if not, execute step S715.

[0062] Step S717: exit the washing function.

[0063] Step S718: after the spinning function is ended, control the shaking function to be enabled.

[0064] Step S719: when the spinning function is running, reduce the initial rotating speed of the program setting, and prolong the program setting time of rising to the final rotating speed of the program setting.

[0066] After the clothes processing device has the control method of the clothes processing device described above, the classification of a small amount of clothes can be further divided, and the corresponding function is executed based on the determined classification of the size of the clothes, so that the phenomenon of clothes eccentricity or wall sticking can be avoided, the clothes processing effect is improved, and the user experience is improved.
