[0002] Most of the existing clothing processing equipment has a drying function. For example, clothes dryers are widely used in daily life, which greatly reduces the time users have to wait for clothes to dry.

[0003] When using a clothes dryer to dry clothes, you need to select a drying program, and the drying program is relatively fixed. Drying clothes in a fixed drying program can lead to over-drying and under-drying of the load. For example, the clothes drying has ended, and the moisture content of the clothes meets the drying requirements, but the dryer is still executing the drying program, resulting in over-drying; or, the clothes drying has not yet achieved the expected effect, and the drying program has ended, resulting in under-drying of the clothes. Therefore, it is impossible to determine the drying time according to the actual situation of the clothes to be dried, which affects the drying effect of the clothes. Summary of the invention

[0043] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. In some embodiments, the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] When clothes handling equipment such as clothes dryers dry a load, it is necessary to select a drying program, which is relatively fixed. Clothes are dried within the fixed drying program, but this may lead to over-drying or under-drying of the load. For example, the clothes drying has been completed and the moisture content of the clothes meets the drying requirements, but the clothes dryer is still executing the drying program, resulting in over-drying; or, the clothes drying program has ended before the expected effect is achieved, resulting in under-drying of the clothes. Therefore, the drying effect of the load is not ideal.

[0046] In view of the above-mentioned defects of the prior art, an embodiment of the present disclosure provides a control method for a clothing processing device. The clothing processing device includes a first clothing processing device and a second clothing processing device, the first clothing processing device is used for cleaning the load, and the second clothing processing device is used for drying the load. The method can be executed by the control device of the clothing processing device provided by the embodiment of the present disclosure, and the control device of the clothing processing device can be implemented in software and / or hardware. The control method of the clothing processing device provided by the embodiment of the present disclosure can be applicable to various types of first clothing processing devices and / or various types of second clothing processing devices of drying. The embodiment of the present disclosure does not limit the type of drying principle, for example, heat pump type or other types are applicable.

[0047] The control method of the clothes processing device and the clothes processing device provided by the embodiments of the present disclosure are exemplarily described below with reference to the accompanying drawings.

[0048] Figure 1 A flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the control method of the clothes processing device includes S110 to S130:

[0049] S110, obtaining the load moisture content of the first laundry processing device.

[0050] The first laundry treatment device is used to clean the load, for example, the load will be washed, rinsed and dehydrated when it is cleaned by the first laundry treatment device. After the first laundry treatment device completes the cleaning of the load, the moisture content of the load is determined, and then it will be dried by the second laundry treatment device.

[0051] If it is necessary to accurately obtain the drying time of the load, the moisture content of the load of the first clothes processing device may be obtained, and then the drying time of the load may be determined in combination with the load weight.

[0052] Exemplarily, the first laundry processing device may send the moisture content of the load to the second laundry processing device. In some optional embodiments, the first laundry processing device may also send the dehydration speed of the load to the second laundry processing device.

[0053] Due to different spin speeds, the moisture content of the load after the spin is completed is different. Therefore, the load moisture content is a parameter related to the spin speed. Based on this, each spin speed corresponds to the load moisture content matched with it. In the embodiment of the present disclosure, the load moisture content can be determined according to the spin speed of the load.

[0054] S120: Obtaining a load weight detected by the second laundry processing device.

[0055] S130, determining the drying time according to the moisture content of the load and the weight of the load.

[0056] The second clothes processing device is used to dry the load. The load after being washed by the first clothes processing device contains a large amount of water. The second clothes processing device can detect the weight of the load. By obtaining the load weight of the second clothes processing device and combining it with the moisture content of the load, the drying time can be determined.

[0057] Specifically, for example, the load weight determined in the above embodiment is set as the dry load weight, and the corresponding relationship between the load weight, moisture content and drying time can be preset. The corresponding relationship can be in the form of a data table, a function corresponding relationship, etc. When the load weight and the load moisture content of the first clothes processing device are determined, the corresponding drying time can be directly determined. In the embodiment of the present disclosure, the corresponding drying time can be matched according to the specific situation of the load, so as to improve the drying effect.

[0058] Exemplarily, based on obtaining the load moisture content of the first laundry processing device, and the load moisture content = (wet load weight - dry load weight) / wet load weight. Therefore, the wet load weight can be determined according to the load moisture content of the first laundry processing device and the load weight (dry load weight) detected by the second laundry processing device, and then the load moisture content can be determined according to the difference between the wet load weight and the dry load weight. The difficulty of drying the load varies with the load moisture content. For example, the more moisture the load contains, the more difficult it is to dry the load, so it takes a longer drying time to dry the load; the less moisture the load contains, the easier it is to dry the load, and it takes a shorter drying time to completely dry the load.

[0059] In an embodiment of the present disclosure, the moisture content of the load in the first clothing processing device is obtained, and the weight of the load detected by the second clothing processing device is obtained. The moisture content of the load can be determined according to the moisture content of the load and the weight of the load. Different moisture contents of the load can determine that there are differences in the difficulty of drying the load, and the required drying time is also different. Therefore, when the clothing processing device of the present disclosure dries the load, it can match the drying time suitable for it according to the actual situation of the load, thereby improving the drying effect of the load.

[0060] In some embodiments, the second laundry processing device includes a distance sensing device, the distance sensing device is used to detect distance information from a load in a laundry processing tub of the second laundry processing device; obtaining the load weight detected by the second laundry processing device includes:

[0061] The distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device is obtained.

[0062] The load weight is determined according to the distance information. The second laundry processing device includes a distance sensing device. When the distance sensing device detects the distance information of the load, the load is placed in the laundry processing tub of the second laundry processing device, and then the distance sensing device detects the distance information between itself and the load in the laundry processing tub of the second laundry processing device.

[0063] Among them, the distance sensing device can be a time-of-flight laser ranging sensor. When measuring the distance, the time-of-flight laser ranging sensor will emit a laser to the position of the load in the clothing processing barrel of the second clothing processing device. The laser contacts the load and is reflected back to the time-of-flight laser ranging sensor. Therefore, the distance information of the load can be determined based on the duration of the laser return.

[0064] The specific position of the time-of-flight laser ranging sensor and the laser emission direction of the time-of-flight laser ranging sensor can be set according to actual needs, and other distance sensing devices can also be used in the embodiments of the present disclosure, and the specific implementation methods will not be described one by one.

[0065] After the distance sensing device obtains the distance information between the load in the laundry processing tub of the second laundry processing device and the distance sensing device, the weight of the load can be determined based on the distance information. Since the larger the load weight, the larger the corresponding volume, the higher the height of the load in the tub; the smaller the load weight, the smaller the corresponding volume, the lower the height of the load in the tub. Therefore, based on the distance information detected by the distance sensing device and the load in the laundry processing tub of the second laundry processing device, the height of the load can be determined, and then the weight of the load corresponding to this height can be determined.

[0066] Exemplarily, the correspondence between the distance information, load height and load weight can be pre-set and stored in a memory. When determining the load weight based on the distance information, the load weight corresponding to the distance information can be found based on the correspondence between the distance information, load height and load weight.

[0067] Exemplarily, multiple sets of distance information may be obtained and feature value extraction may be performed, such as extracting the maximum value, minimum value, average value, and variance from the multiple sets of distance information, and determining the load weight based on the extracted feature values.

[0068] Optionally, in the embodiment of the present disclosure, the load weight determined according to the distance information refers to the dry load weight. In other embodiments, the wet load weight corresponding to the distance information can also be found according to the correspondence between the distance information, the load height and the wet load weight.

[0069] In some embodiments, obtaining the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device includes:

[0070] The distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing apparatus detected when the laundry processing tub of the second laundry processing apparatus is in a stationary state is acquired.

[0071] When the laundry processing tub of the second laundry processing device is in a stationary state, the load in the tub also remains stationary. When the distance sensing device detects, the distance between the distance sensing device and the load remains unchanged, so the detected distance information is more accurate. If the laundry processing tub of the second laundry processing device is in a rotating state for detection, the load will flip in the laundry processing tub of the second laundry processing device, causing the distance between the distance sensing device and the load to fluctuate continuously, and it is impossible to obtain accurate and fixed distance information. Therefore, the embodiment of the present disclosure obtains the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device detected by the distance sensing device when the laundry processing tub of the second laundry processing device is in a stationary state.

[0072] Optionally, in some other embodiments, when the rotation speed of the laundry processing tub of the second laundry processing device is slow, the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device is obtained. Since the rotation speed of the laundry processing tub of the second laundry processing device is slow, the load turnover degree is weak, and the distance fluctuation between the distance sensing device and the load is small, if the distance information is detected at this time, it is also relatively accurate.

[0073] In some embodiments, obtaining the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device when the laundry processing tub of the second laundry processing device is in a stationary state comprises:

[0074] The distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing apparatus detected during the stop phase of the rotation rhythm of the laundry processing tub of the second laundry processing apparatus is obtained.

[0075] In the embodiment of the present disclosure, the clothing processing barrel of the second clothing processing device is in a stationary state, including a stop phase of the rotation rhythm of the clothing processing barrel of the second clothing processing device. During this phase, the distance information of the load is detected, which meets the requirements for detection in a stationary state, and the distance information obtained is relatively accurate.

[0076] The clothes processing barrel of the second clothes processing equipment has a rotation rhythm during the drying load process. During the rotation stage of the rotation rhythm, the clothes processing barrel of the second clothes processing equipment can shake out the load in the barrel to make the load scattered more evenly. In order to avoid the problem that the clothes processing barrel of the second clothes processing equipment continuously rotates, resulting in excessive power or affecting the life of the clothes processing barrel of the second clothes processing equipment, there will also be a stop stage in the rotation rhythm. During the stop stage, the clothes processing barrel of the second clothes processing equipment is equivalent to a static state, and the load in the barrel remains stationary and will not flip. When the distance sensing device detects the load distance, the distance between the distance sensing device and the load is fixed and will not change. Therefore, the distance information between the distance sensing device and the load in the clothes processing barrel of the second clothes processing equipment detected by the distance sensing device during the stop stage of the rotation rhythm of the clothes processing barrel of the second clothes processing equipment is more accurate.

[0077] In some embodiments, obtaining the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device detected during the stop phase of the rotation rhythm of the laundry processing tub of the second laundry processing device includes:

[0078] The laundry processing tub of the second laundry processing device is controlled to rotate according to the first rotation rhythm.

[0079] The distance information between the distance sensing device and the load in the laundry treatment tub of the second laundry treatment device detected during the stop phase of the first rotation cycle is obtained.

[0080] The first rotation rhythm includes rotating in a first direction, stopping, rotating in a second direction and stopping; the first direction is opposite to the second direction.

[0081] In the embodiment of the present disclosure, a first rotation rhythm is provided to control the clothing processing barrel of the second clothing processing device to rotate according to the first rotation rhythm. The rotation can make the load more evenly scattered, avoiding uneven load distribution and inconsistent height, which affect the accuracy of the detected distance information.

[0082] In the first rotation rhythm, the clothing processing barrel of the second clothing processing device performs corresponding operations in the order of rotating in the first direction, stopping rotating, rotating in the second direction, and stopping rotating. By controlling the load to rotate in different directions, the load is fully shaken and flattened. The first direction is opposite to the second direction, for example, the first direction is forward, and the second direction is reverse. The clothing processing barrel of the second clothing processing device performs corresponding operations according to this rotation rhythm. When the clothing processing barrel of the second clothing processing device is in the stop stage, the load stops flipping and is in a stationary state. At this time, the distance information of the load detected by the distance sensing device is obtained, and the distance information is relatively accurate and there will be no fluctuations. Furthermore, the load weight can be obtained more accurately.

[0083] In some embodiments, obtaining the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device detected during the stop phase of the first rotation rhythm includes:

[0084] The distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device detected in two adjacent stop stages in the first rotation cycle is obtained.

[0085] When the laundry processing tub of the second laundry processing device rotates according to the first rotation rhythm, the laundry processing tub of the second laundry processing device will rotate in the first direction, stop, rotate in the second direction, and stop in sequence. In order to avoid the problem of uneven load distribution and inconsistent height affecting the accuracy of the detection distance information, the distance information of the load in the laundry processing tub of the second laundry processing device detected by the distance sensing device in two adjacent stop stages in the first rotation rhythm can be obtained.

[0086] After obtaining the distance information detected in the first stop phase, the clothes processing barrel of the second clothes processing device will rotate, and the load in the barrel will be scattered during the rotation. After the clothes processing barrel of the second clothes processing device stops again, the distance information detected in the second stop phase is obtained. If the distance information detected in two adjacent stop phases is similar, it can be determined that the load is relatively stable and the data is accurate; if the distance information detected in two adjacent stop phases fluctuates greatly, the average value can be taken for balancing to reduce the error caused by uneven load height. In order to obtain a more accurate load weight.

[0087] In some embodiments, the time of rotation in the second direction in the first rotation beat is greater than the time of rotation in the second direction in the second rotation beat.

[0088] The second rotation rhythm is the rotation rhythm of the clothes processing drum of the second clothes processing device when the drying component is in operation.

[0089] In the disclosed embodiment, a first rotation rhythm and a second rotation rhythm are also provided. The clothes processing barrel of the second clothes processing device rotates according to the first rotation rhythm, and the distance information between the distance sensing device and the load in the clothes processing barrel of the second clothes processing device is detected in the stop phase of the first rotation rhythm. When the clothes processing barrel of the second clothes processing device rotates according to the second rotation rhythm, the drying component of the clothes processing device of the second clothes processing device is in operation, and the drying component performs a drying operation on the load in the barrel. The second rotation rhythm is the rotation rhythm of the clothes processing barrel of the second clothes processing device when the drying component is in operation, mainly for performing a drying operation to dry the load, and usually rotating in the first direction for a longer time to avoid frequent changes in the rotation direction and affecting the drying efficiency. Rotating at the first rotation rhythm is mainly to improve the accuracy of obtaining the distance information between the distance sensing device and the load in the clothes processing barrel of the second clothes processing device detected in the stop phase, and to determine the load weight.

[0090] If the load weight is to be determined accurately, it is necessary to improve the accuracy of the acquired load distance information to avoid uneven load distribution and inconsistent height, which will cause large fluctuations in the acquired load distance information and affect the accuracy. The role of the first rotation rhythm is to fully shake out the load. By increasing the time that the clothing processing barrel of the second clothing processing device rotates along the second direction, the load can have more sufficient time to be shaken and evenly distributed in the barrel. Therefore, the load distance information is acquired within the first rotation rhythm, and the time for rotation in the second direction is increased, so that the time for rotation in the second direction in the first rotation rhythm is greater than the time for rotation in the second direction in the second rotation rhythm. This can make the load distribution more even, detect the distance information of the load more accurately, and improve the accuracy of obtaining the load weight.

[0091] For example, in the first rotation rhythm, the laundry processing barrel of the second laundry processing device rotates in the first direction for 1 minute, stops for 5 seconds, rotates in the second direction for 1 minute, and stops for 5 seconds. In the second rotation rhythm, the laundry processing barrel of the second laundry processing device rotates in the first direction for 15 minutes, stops for 5 seconds, rotates in the second direction for 10 seconds, and stops for 5 seconds. The time of rotation in the second direction in the first rotation rhythm is greater than the time of rotation in the second direction in the second rotation rhythm, which can make the load distribution more uniform, obtain the distance information of the load more accurately, and thus improve the accuracy of obtaining the load weight.

[0092] In some embodiments, the time of rotation in the first direction and the time of rotation in the second direction in the first rotation rhythm are the same.

[0093] The first rotation rhythm also includes the stages of rotation in the first direction and rotation in the second direction. Since the rotation in the first direction and the rotation in the second direction are to fully shake off the load, the load is evenly distributed in the laundry processing tub of the second laundry processing device to avoid inconsistent loads. Therefore, the time of rotation in the first direction and the time of rotation in the second direction in the first rotation rhythm can be made the same to make the load evenly distributed.

[0094] For example, when the laundry treatment barrel of the second laundry treatment device rotates at the first rhythm, the first direction can be set to the forward direction and the second direction can be set to the reverse direction, and the time for rotating in the first direction can be the same as the time for rotating in the second direction. For example, the laundry treatment barrel of the second laundry treatment device rotates in the forward direction for 2 seconds and in the reverse direction for 2 seconds, and the two times are the same, so as to evenly shake off the load. The specific rotation time can be set according to actual needs, and the embodiments of the present disclosure do not limit this.

[0095] Optionally, the difference between the time of rotation in the first direction and the time of rotation in the second direction in the first rotation rhythm can be made smaller than a difference threshold. The difference threshold is small, that is, the difference between the time of rotation in the first direction and the time of rotation in the second direction is small, and because both the rotation in the first direction and the rotation in the second direction can make the load evenly distributed, accurate load distance information can be collected in the stopping stage after the rotation in the first direction and the stopping stage after the rotation in the second direction.

[0096] In some embodiments, the time for rotating in the first direction and the time for rotating in the second direction in the first rotation rhythm are both greater than the stop time in the first rotation rhythm.

[0097] The first rotation rhythm includes rotating in a first direction, stopping, rotating in a second direction and stopping, and the first direction is opposite to the second direction.

[0098] Among them, the rotation of the clothing processing barrel of the second clothing processing device in the first direction and in the second direction is to fully shake out the load, so that the load is evenly distributed in the clothing processing barrel of the second clothing processing device to avoid inconsistent load height. The clothing processing barrel of the second clothing processing device stops rotating in order to accurately obtain the distance information of the load. When the clothing processing barrel of the second clothing processing device is in the stop stage, the load in the barrel stops flipping and there will be no fluctuation. The distance sensing device can quickly detect the distance information of the load, and the required detection time is short; while shaking out the load and scattering it evenly requires a longer time. Therefore, in the first rotation rhythm, the rotation time of the clothing processing barrel of the second clothing processing device should be greater than the stop time.

[0099] In some embodiments, obtaining the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device when the laundry processing tub of the second laundry processing device is in a stationary state includes:

[0100] It is determined that the driving motor of the laundry processing tub of the second laundry processing device is in a stopped state, and distance information from the load in the laundry processing tub of the second laundry processing device detected by the distance sensing device is obtained.

[0101] Specifically, in the clothing processing device of the second clothing processing device, the rotation of the driving motor drives the clothing processing tub of the second clothing processing device to rotate. Therefore, it is possible to determine whether the clothing processing tub of the second clothing processing device is in a stationary state by judging whether the driving motor of the clothing processing tub of the second clothing processing device is running.

[0102] When the driving motor of the clothing processing tub of the second clothing processing device is in operation, the driving motor can drive the clothing processing tub of the second clothing processing device to rotate. At this time, the clothing processing tub of the second clothing processing device is not in a static state. If the distance information of the load is detected by the distance sensing device, the detection result is inaccurate. If the driving motor of the clothing processing tub of the second clothing processing device is in a stopped state, it can be determined that the clothing processing tub of the second clothing processing device is not rotating and is in a static state, and the distance information of the load can be detected by the distance sensing device. Since the loads remain stationary and the position between the distance sensing device and the load is fixed, the distance information of the load in the clothing processing tub of the second clothing processing device detected by the distance sensing device is more accurate and there is no possibility of fluctuation.

[0103] Thus, it can be determined whether detection can be performed by determining the operating state of the driving motor of the laundry processing tub of the second laundry processing device. For example, it is determined that the driving motor of the laundry processing tub of the second laundry processing device is in a stopped state, and the distance information detected by the distance sensing device to the load in the laundry processing tub of the second laundry processing device is obtained.

[0104] In some embodiments, obtaining the distance information between the distance sensing device and the load in the laundry processing tub of the second laundry processing device when the laundry processing tub of the second laundry processing device is in a stationary state includes:

[0105] Determining that a change difference between the distance information detected by the distance sensing device and the load in the laundry processing tub of the second laundry processing device within a preset time is less than a first difference threshold, and determining that the laundry processing tub of the second laundry processing device is in a stationary state;

[0106] The distance information between the load in the laundry processing tub of the second laundry processing device and the distance detected by the sensing device within a preset time is used as the distance information for determining the load weight.

[0107] According to the distance information detected by the distance sensing device and the load in the laundry processing tub of the second laundry processing device, it can also be determined whether the laundry processing tub of the second laundry processing device is in a stationary state, thereby determining the effective distance information detected by the distance sensing device.

[0108] Specifically, the distance sensing device is relatively fixedly arranged in the laundry processing tub of the second laundry processing device, and when the laundry processing tub of the second laundry processing device is in a rotating state or a stationary state, the distance sensing device can obtain the distance information of the load in real time. However, when the laundry processing tub of the second laundry processing device is in different states, the distance information obtained is different.

[0109] When the clothes processing barrel of the second clothes processing device is in a rotating state, the load in the clothes processing barrel of the second clothes processing device is also constantly flipped. During the flipping process, the load position is constantly changing, and the load height is also constantly changing. If the distance information of the load is obtained in the rotating state, the data fluctuates greatly. When the clothes processing barrel of the second clothes processing device is in a stationary state, the load in the clothes processing barrel of the second clothes processing device is fixed and the load height remains unchanged. If the distance information of the load is obtained in a stationary state, the data fluctuates less. Therefore, a first difference threshold value can be set. When the distance information detected by the distance sensing device and the load in the clothes processing barrel of the second clothes processing device has a small change difference within a preset time and is less than the first difference threshold value, it is determined that the clothes processing barrel of the second clothes processing device is in a stationary state at this time, and the distance information obtained at this time fluctuates less. This data can be used to more accurately determine the load weight.

[0110] Based on this, the state of the laundry processing tub of the second laundry processing device can be determined by whether the change difference of the distance information detected by the distance sensing device to the load in the laundry processing tub of the second laundry processing device within a preset time is less than the first difference threshold.

[0111] Furthermore, when the clothing processing barrel of the second clothing processing device is in a stationary state, the distance information between the distance sensing device and the load in the clothing processing barrel of the second clothing processing device is more accurate, and the distance information between the distance sensing device and the load in the clothing processing barrel of the second clothing processing device within a preset time can be used as the distance information for determining the load weight.

[0112] In some embodiments, before acquiring the load weight detected by the second laundry processing device, the method further includes:

[0113] It is determined that the drying component of the second laundry processing apparatus is in a stopped state.

[0114] In order to ensure the accuracy of the detected load weight (dry load weight), the weight of the load (wet load) in the laundry treatment barrel should be prevented from changing. If the drying component of the second laundry treatment device is in operation when detecting the distance information of the load, the water content of the load in the barrel will be reduced by heat, causing the weight of the load in the barrel to change, affecting the detected load weight (dry load weight). When the drying component of the second laundry treatment device is in a stopped state, the drying component does not dry the load, and the water content of the load will not change. The load weight detected by the second laundry treatment device at this time is the accurate load weight.

[0115] Therefore, it is most accurate to determine that the drying assembly of the second laundry processing apparatus is in a stopped state and to obtain the distance information detected by the distance sensing device to the load in the laundry processing tub of the second laundry processing apparatus.

[0116] Exemplarily, the present disclosure explains the complete process of the control method of the laundry processing device with a specific embodiment:

[0117] Figure 2 Another control method of a clothes processing device provided by the embodiment of the present disclosure is as follows: Figure 2 As shown, the control method includes:

[0118] S200, start.

[0119] S201, putting a dehydrated load into the second clothes processing device and starting the program.

[0120] S202, determining whether the second laundry processing device receives the dehydration speed of the load in the first laundry processing device. If yes, executing S203; otherwise, executing S204.

[0121] S203, obtaining the dehydration speed of the load.

[0122] S204, setting the default spin speed to the spin speed of the load.

[0123] In some optional embodiments, if the second clothes processing device does not receive the dehydration speed of the load in the first clothes processing device, a default dehydration speed may be used.

[0124] S205: Determine the moisture content of the load according to the dehydration speed of the load.

[0125] S206: Determine that the drying component is in a stopped state, and control the clothes processing drum of the second clothes processing device to rotate according to a first rotation rhythm.

[0126] S207, the second laundry processing device stops t1 after rotating forward, and the distance sensing device detects distance information.

[0127] S208: The second laundry processing device is reversed and then stops t2, and the distance sensing device detects the distance information.

[0128] S209, feature value extraction: maximum value, minimum value, mean value, variance.

[0129] Based on the multiple distance information detected in step S207 and step S208, feature value extraction is performed, for example, the maximum value, minimum value, average value and variance in the distance information are extracted.

[0130] S210: Determine the load weight according to the distance information.

[0131] Specifically, there is a corresponding relationship between the distance information and the load weight, and the load weight can be obtained based on the feature value extracted in the above steps. In this case, the dry load weight is obtained.

[0132] S211, displaying the drying load weight.

[0133] S212: Determine the water content of the load according to the water content of the load in the laundry processing tub and the weight of the load.

[0134] S213: Determine a drying time based on the moisture content of the load and a drying parameter of the clothes processing equipment.

[0135] S300, end.

[0136] On the basis of the above embodiments, the present disclosure also provides a control device for a clothes processing device, which can be used to execute the steps of any of the control methods for clothes processing devices in the above embodiments to achieve corresponding beneficial effects. The detection of the load weight in the clothes processing device can be understood by referring to the above, and will not be repeated here.

[0137] For example, Figure 3 A schematic diagram of the structure of a clothes processing device provided by an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, the embodiment of the present disclosure also provides a laundry processing device, including: a first laundry processing device and a second laundry processing device; the first laundry processing device is used for cleaning loads, and the second laundry processing device is used for drying loads. The second laundry processing device includes a laundry processing tub 1 and a distance sensing device 2.

[0138] The laundry treatment tub 1 is used to hold a load. The distance sensing device 2 is used to detect distance information from the load in the laundry treatment tub.

[0139] The loads are all located at the bottom of the laundry treatment tub 1, and the distance sensing device 2 is arranged in the laundry treatment device and is located in the same space as the loads so as to directly sense the distance between the loads and the loads. For example, the distance sensing device 2 is located above the loads, and the distance sensing device 2 can send a detection signal to the bottom where the loads are located, thereby obtaining the distance information of the loads.

[0140] Exemplarily, the distance sensing device is a time-of-flight laser distance sensor, which is disposed in the laundry processing device, and the load is located at the bottom of the laundry processing tub. When measuring the distance, the time-of-flight laser distance sensor emits a laser toward the load, and the laser contacts the load and is reflected back to the time-of-flight laser distance sensor, and the distance information of the load is determined based on the time length of the laser return.

[0141] In some embodiments, continue to refer to Figure 3 , further comprising a front support plate 3. The front support plate 3 is used to support the laundry treatment tub 1.

[0142] The distance sensing device 2 is arranged at the highest position of the front supporting plate 3 .

[0143] The clothes processing device further includes a front support plate 3, which is used to support the clothes processing barrel 1 to increase its stability. The front support plate 3 is located in front of the clothes processing barrel 1, close to the barrel door. Based on the structural characteristics of the clothes processing device itself, when drying the load, the load is mostly concentrated in the front position of the clothes processing barrel 1. Therefore, in order to detect the distance information of the load, the distance sensing device 2 is set on the front support plate 3 to avoid the situation where there is no load at the position sensed by the distance sensing device 2.

[0144] The distance sensing device 2 is set at the highest position of the front support plate 3 to prevent the distance sensing device 2 from being too low. The load in the clothing treatment barrel 1 is all below the distance sensing device 2. Loads of any weight can be sensed without the distance sensing device 2 being lower than the load position.

[0145] The angle and specific setting height of the distance sensing device 2 can be adjusted according to actual needs to increase the detection range, and the embodiments of the present disclosure do not limit this.

[0146] In some other embodiments, other devices or other types of sensors may be used as distance sensing devices, which is not limited in the present disclosure and can be selected according to actual needs.
