[0001] The present application relates to the field of clothes treatment equipment, and particularly provides a clothes treatment equipment control method and clothes treatment equipment. BACKGROUND

[0002] The pulsator washing machine is driven by a motor to rotate a pulsator, and with the rotation of the pulsator, water flow in the washing machine is stirred to realize that clothes are constantly tumbled with the water flow.

[0003] When a user uses the washing machine to wash clothes, many existing washing machines need the user to manually put in detergent. The user usually puts in detergent into the washing machine according to his or her intuition, and the amount of detergent put in may not match the corresponding washing program, which may cause the amount of detergent to be too much or too little, and further cause clothes to have too much foam, detergent residue or not to be clean, and reduce the user experience.

[0004] In the prior art, in order to match the washing program with the amount of detergent, a detergent automatic feeding device is usually arranged in the washing machine. After the washing program is determined, the amount of detergent fed by the detergent automatic feeding device is determined according to the relevant washing parameters in the washing program. However, this technical means is not applicable to the case where the user has already put detergent into the washing machine, such as the case where the user who is not familiar with the function of the washing machine directly puts detergent into the washing machine.

[0010] In the preferred technical solution of the control method of the laundry treatment apparatus, the step of controlling the motor that drives the rotation of the impeller of the laundry treatment apparatus further comprises: controlling the motor that drives the rotation of the impeller of the laundry treatment apparatus to rotate at a preset washing rotation-stop ratio.

[0011] In the preferred technical solution of the control method of the laundry treatment apparatus, the step of executing an optimized washing mode based on the dosage of the detergent further comprises: when it is determined that the dosage level of the detergent is “more”, controlling the water inlet function to be enabled; when the water inlet reaches a target preset water level, controlling the water inlet function to be disabled; and controlling the rotation-stop ratio of the motor that drives the rotation of the impeller of the laundry treatment apparatus to decrease; wherein the set water level is less than the target preset water level.

[0012] In the preferred technical solution of the control method of the laundry treatment apparatus, the step of executing an optimized washing mode based on the dosage of the detergent further comprises: when it is determined that the dosage level of the detergent is “more”, and after the washing function ends, controlling the rinsing function to be performed according to a first preset number of rinsing times; wherein the first preset number of rinsing times is greater than a program set number of rinsing times.

[0013] In the preferred technical solution of the control method of the laundry treatment apparatus, the step of executing an optimized washing mode based on the dosage of the detergent further comprises: when it is determined that the dosage level of the detergent is “less”, controlling the heating function to be enabled.

[0014] In the preferred technical solution of the control method of the laundry treatment apparatus, the step of executing an optimized washing mode based on the dosage of the detergent further comprises: when it is determined that the dosage level of the detergent is “very less”, controlling the water inlet function to be enabled; when the water inlet reaches a target preset water level, controlling the water inlet function to be disabled; and controlling the rotation-stop ratio of the motor that drives the rotation of the impeller of the laundry treatment apparatus to increase; wherein the set water level is less than the target preset water level.

[0015] In the preferred technical scheme of the control method of the laundry treating apparatus, the set water level is obtained based on the following method: obtaining a time interval from the last time when the washing function is enabled; determining a first preset water level as the set water level when the time interval is greater than a preset time interval; determining a second preset water level as the set water level when the time interval is less than or equal to the preset time interval; wherein the first preset water level is greater than the second preset water level; and / or the step of "obtaining the motor parameter" further comprises: obtaining the motor parameter after a preset time elapses.

It has been found by the applicant that the detergent dosage is related to the power of the motor, i.e., when the detergent dosage is relatively large, the friction between the laundry and the drum wall, between the laundry, and between the laundry and the pulsator is small, so that the power of the motor driving the pulsator to rotate is also small. As the detergent dosage decreases, the friction between the laundry and the drum wall, between the laundry, and between the laundry and the pulsator increases, so that the power of the motor driving the pulsator to rotate also increases. Therefore, the detergent dosage can be determined based on the motor parameter, and an optimized washing mode can be executed based on the detergent dosage, so that the detergent dosage can be accurately determined even if the user has already put the detergent into the washing machine, and the phenomenon of excessive foam, detergent residue, or poor washing caused by the mismatch between the detergent dosage and the corresponding washing program can be avoided, thereby reducing the user experience.

[0020] Figure 1 is the main flowchart of the control method of the laundry treating apparatus of the present application;

[0021] Figure 2is a possible logic diagram of the control method of the laundry treating apparatus of the present application. DETAILED DESCRIPTION

[0022] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection 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 determine the amount of detergent when the user has already put detergent into the washing machine, thereby causing poor washing effect. The present application provides a control method of a laundry treating apparatus, wherein the specific form of the laundry treating apparatus of the present application includes a plurality of forms, for example, it can be a washing machine or a washer-dryer, etc. In order to facilitate description, the laundry treating apparatus of the present application will be introduced as a washing machine hereinafter, specifically, as shown in Figure 1 The control method of the present application comprises the following steps:

[0025] Step S100: after entering the washing function, control water to a set water level.

[0026] Specifically, the way of entering the washing function of the washing machine includes a plurality of 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. After entering the washing function, the washing machine can first obtain the target preset water level, wherein the target preset water level can be the water level selected by the user himself, or can be determined based on the weight of the clothes, such as obtaining the weight of the clothes through the weighing sensor or fuzzy weighing of the washing machine, etc. The target preset water level can be determined based on the pre-stored clothes weight-target preset water level corresponding table in the washing machine or through a deep learning model, etc. After obtaining the target preset water level, at the same time or before, control water to a set water level. Wherein the set water level is less than the target preset water level. Preferably, the set water level is obtained based on the following method.

[0027] Obtain the time interval from the last time the washing function is started; when the time interval is greater than the preset time interval, determine the first preset water level as the set water level; when the time interval is less than or equal to the preset time interval, determine the second preset water level as the set water level; wherein the first preset water level is greater than the second preset water level.

[0028] In other words, the time interval between the current activation of the washing function and the last activation of the washing function indicates how long the user has gone without washing clothes. This allows for an estimate of the approximate amount of laundry to be washed. When the time interval is greater than a preset interval, the user has accumulated more unwashed laundry, requiring more water, thus the first preset water level is higher. Conversely, when the time interval is less than or equal to the preset interval, the user has accumulated less unwashed laundry, requiring less water, thus the second preset water level is lower. In other words, the first preset water level is higher than the second preset water level. The preset time interval can be obtained through experiments or empirical methods.

[0029] Since the amount of detergent used by the user is uncertain, a set water level lower than the target preset water level can be determined based on the time interval since the last wash function was activated, so as to avoid adding too much water and reducing the washing effect of the detergent.

[0030] Step S200: Control the motor that drives the pulsator of the washing machine to rotate.

[0031] Once the water level reaches the set level, the motor controlling the pulsator of the washing machine starts rotating. The rotation of the pulsator agitates the water, ensuring the detergent is mixed evenly. Preferably, the motor rotates at a preset washing start-stop ratio, which is the start-stop ratio pre-set in the program for use during the washing cycle.

[0032] It is understood that although the motor of the present invention is described as rotating at a preset washing start-stop ratio, this is not intended to limit the scope of protection of the present invention. For example, the motor may rotate at a start-stop ratio that is less than the preset washing start-stop ratio.

[0033] Furthermore, as an alternative implementation, the motor rotating at a preset washing start-stop ratio can be replaced by the motor rotating at a preset washing speed, etc.

[0034] Step S300: Obtain motor parameters.

[0035] Preferably, motor parameters can be acquired after a preset time has elapsed since the motor controlling the pulsator of the washing machine began rotating. This ensures thorough mixing of detergent, clothes, and water, resulting in more accurate motor parameters. The preset time can be based on experimental values ​​or set directly based on experience. Alternatively, motor parameters can be acquired while the motor is rotating, and the detergent dosage can be determined based on these parameters after the preset time has elapsed.

[0036] Preferably, the motor parameter is motor power, but other parameters can be used instead, such as motor current. For ease of explanation, the motor parameters of this invention will be described below using motor power as an example. That is, the control methods related to motor power are also applicable to motor current.

[0037] Step S400: determining the detergent dosage based on the motor parameter.

[0038] Preferably, the detergent dosage level can be determined based on the range in which the motor power is located. For example, the present application divides the detergent dosage level into three, namely "more", "less" and "very less", wherein the detergent dosage level of "more" is greater than that of "less", and the detergent dosage level of "less" is greater than that of "very less". Specifically, when the motor power is less than the first preset power, the detergent dosage level is determined as "more"; when the motor power is greater than or equal to the first preset power and less than or equal to the second preset power, the detergent dosage level is determined as "less"; when the motor power is greater than the second preset power, the detergent dosage level is determined as "very less". It can be understood that the present application does not limit the specific type of detergent as long as it can be dissolved in water for washing clothes, which is within the protection scope of the present application, such as liquid or powder, etc., which can be laundry liquid or softener, etc., which does not deviate from the principle of the present application.

[0039] When the motor drives the pulsator to rotate, the pulsator will stir the water flow in the washing machine, so that the water flow has a certain water flow intensity. In this case, the applicant found that the detergent dosage is related to the motor power, i.e. when the detergent dosage is more, the friction between the clothes and the barrel wall, the clothes and the clothes, and the clothes and the pulsator is smaller, so that the power of the motor driving the pulsator to rotate is also smaller. With the decrease of the detergent dosage, the friction between the clothes and the barrel wall, the clothes and the clothes, and the clothes and the pulsator will increase, so that the power of the motor driving the pulsator to rotate will also increase. Therefore, in order to accurately divide the detergent dosage, the present application determines the detergent dosage level when the motor power is less than the first preset power as "more"; determines the detergent dosage level when the motor power is greater than or equal to the first preset power and less than or equal to the second preset power as "less"; and determines the detergent dosage level when the motor power is greater than the second preset power as "very less", wherein the first preset power and the second preset power can be obtained based on experiments.

[0040] By determining the detergent dosage based on the motor parameter, the detergent dosage can be accurately determined even if the user has already put detergent into the washing machine, so as to avoid the phenomenon of excessive clothes foam, detergent residue or poor washing caused by the mismatch between the detergent dosage and the corresponding washing program, thereby reducing the user experience.

[0041] In addition, it can be understood that although the present application is introduced by determining the dosage level of the detergent based on the range of the motor power, it is not intended to limit the protection scope of the present application, for example, the dosage of the detergent can not be graded, but the dosage of the detergent can be directly estimated, for example, a comparison table of the motor power and the dosage of the detergent under a known water level can be established in advance, so that the corresponding comparison table can be found based on the set water level, and then the dosage of the detergent can be determined based on the power value, and the like, which do not deviate from the principles of the present application and are within the protection scope of the present application.

[0042] Step S500: performing an optimized washing mode based on the dosage of the detergent.

[0043] Possibly, when it is determined that the dosage level of the detergent is "more", the water inlet function is controlled to be enabled, and when the water inlet reaches the target preset water level, the water inlet function is controlled to be closed; the rotation stop ratio of the motor driving the rotation of the impeller of the washing machine is reduced.

[0044] That is, when the dosage of the detergent is more, the washing machine starts to inlet water, and stops to inlet water until the water inlet reaches the target preset water level. Since the dosage of the detergent is more, in order to avoid the phenomenon of excessive washing foam or detergent residue during washing, the detergent is diluted by increasing the amount of water, so that the concentration of the detergent is reduced, and after the water inlet reaches the target preset water level, the rotation stop ratio of the motor is reduced. At this time, the rotation stop ratio of the motor is less than the preset washing rotation stop ratio, that is, the water flow intensity is reduced. First, since the dosage of the detergent is more, the dirt of the clothes is more easily removed, so that it is not necessary to use a strong water flow intensity, which can save energy. Second, by reducing the water flow intensity, the phenomenon of excessive washing foam can also be avoided. Of course, when the motor rotates at the preset washing rotation speed, the preset washing rotation speed can be reduced.

[0045] Possibly, after the washing function is finished, the rinsing function is controlled to run according to the first preset rinsing number, wherein the first preset rinsing number is greater than the program setting rinsing number. For example, it is one more than the program setting rinsing number, so that the phenomenon of detergent residue can be avoided.

[0046] Possibly, when it is determined that the dosage level of the detergent is "less", the heating function is controlled to be enabled.

[0047] That is, at this time, the original set water level is kept unchanged, and the heating function is controlled to be enabled to heat the washing water, so as to accelerate the dissolution of the detergent, effectively remove the dirt of the clothes, and improve the washing effect. At this time, the washing machine can rinse according to the program setting rinsing number. It can be understood that the washing machine of the prior art generally has a heating function, which is to set a heating device on the washing machine to heat the water, such as setting a heating pipe on the inside or outside of the outer barrel.

[0048] Possibly, when it is determined that the amount of the detergent is "little", the water inlet function is controlled to be enabled; when the water is filled to the target preset water level, the water inlet function is controlled to be closed; and the rotation stop ratio of the motor driving the rotation of the pulsator of the washing machine is increased.

[0049] That is, when the amount of the detergent is little, the washing machine starts to fill water and stops to fill water when the water is filled to the target preset water level. Since the amount of the detergent is little, if the original lower water level is still used for washing, the friction between the clothes will be larger, which can cause damage to the clothes and reduce the washing effect. In order to avoid this phenomenon, the water is added to the target preset water level, and the rotation stop ratio of the motor is increased. At this time, the rotation stop ratio of the motor is greater than the preset washing rotation stop ratio, that is, the washing intensity is increased to improve the washing effect. At this time, the washing machine can perform rinsing according to the rinsing times set by the program. Of course, when the motor rotates at the preset washing rotation speed, the preset washing rotation speed can be increased.

[0050] In summary, the above control method can accurately determine the amount of the detergent when the user has put the detergent into the washing machine, so that the optimal washing function can be matched based on the amount of the detergent, thereby improving the washing effect and having strong universality and practicality.
