[0050] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0051] With reference to Figure 1 , Figure 1 The present application relates to a clothes drying control device.

[0052] As shown in Figure 1 , the clothes drying control device can be applied to a clothes treatment device, and the clothes drying control device can include a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005, wherein the communication bus 1002 is used to realize the connection communication between the components. The user interface 1003 can include a standard wired interface, a wireless interface. The network interface 1004 can optionally include a standard wired interface, a wireless interface. The memory 1005 can be a high-speed random access memory (RAM) memory, and can also be a stable non-volatile memory (NVM), such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art can understand that Figure 1 the structure shown in the above does not constitute a limitation on the clothes drying control device, and can include more or fewer components than the drawings, or combine certain components, or different component arrangements.

[0054] As shown in Figure 1 , the memory 1005 as a storage medium can include an operating system, a data storage module, a network communication module, a user interface module, and a computer program.

[0055] In Figure 1In the clothes drying control device shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and memory 1005 in the clothes drying control device of this application can be set in the clothes processing equipment. The clothes drying control device calls the computer program stored in the memory 1005 through the processor 1001 and executes the clothes drying control methods of various embodiments provided in this invention.

[0056] This application also provides a clothing drying control method, which is applied to clothing processing equipment, as described above. Figure 3 and Figure 4 The garment processing equipment includes a drum 1 and a drum drive motor (not shown in the figure). The drum drive motor drives the drum 1 to rotate. The garment processing equipment also includes an air duct 3, which connects to the internal space of the drum 1. An internal / external circulation switching valve 2 is installed at the connection between the air inlet and outlet of the air duct 3. A fan 4 is installed in the air duct 3, and the fan 4 operates to drive the airflow in the air duct 3. A heating wire is installed at the connection between the air inlet of the air duct 3 and the internal space of the drum 1 to heat the airflow flowing through and entering the drum 1. A condenser 5 is installed near the outlet in the air duct 3 to cool, condense, and dehumidify the humid airflow flowing through the air duct 3. The internal / external circulation switching valve 2 is used to switch the airflow in the air duct between internal and external circulation. For example, when the internal / external circulation switching valve 2 is in the closed state, the air inlet and outlet of the air duct 3 are closed, and the channels where the air inlet and outlet are connected are closed. Figure 3 As shown; the internal / external circulation switching valve 2 is in the open state, connecting the external space with the air inlet and outlet of the air duct 3 respectively, while blocking the passage where the air inlet is located and the passage where the air outlet is located, as shown. Figure 4 As shown.

[0057] In some feasible embodiments, the clothing drying control method of this application uses a clothes dryer as the clothing processing equipment. As briefly described above, the clothes dryer removes moisture from the clothes by contacting hot air with the damp clothes. The hot air is heated by an electric heating wire at the air inlet of the air duct. The moisture is condensed into liquid water by the condenser in the air duct and discharged or directly discharged to the external environment through the air outlet of the air duct. This cycle continues until the clothes are completely dry, at which point the drying program (also known as the drying process) of the clothes dryer is stopped, and the clothes dryer stops working.

[0058] Currently, the drying judgment algorithm of the clothes dryer mainly judges drying through the temperature difference between the air inlet and the air outlet of the clothes dryer. This method is easily affected by the state of the clothes in the drum and cannot effectively achieve drying and stopping, resulting in poor user experience. For example, when the clothes in the drum are tangled, the outside of the clothes is dry, and the inside is slightly damp. However, since the outside of the clothes is already dry, the temperature difference between the air inlet and the air outlet is small, which may misjudge that the clothes are already dry, i.e., the drying judgment algorithm is inaccurate, the drying time is not accurate, and the drying program stops before the clothes are completely dried.

[0059] To solve the technical problems of inaccurate drying time and poor user experience of the clothes dryer in the conventional technology, the core inventive concept of the present application is that during the operation of the clothes dryer, the remaining drying time (i.e., the first remaining time) needs to be displayed in a short time when the drying program (also referred to as the drying process) is started. The first remaining time can be determined first, and then adjusted to obtain the second remaining time when the running parameters of the clothes dryer trigger the preset drying condition. The second remaining time is more consistent with the actual situation of completely drying the clothes in the clothes dryer. When the second remaining time of the drying process ends, the drying process is closed, which improves the accuracy of the drying time and improves the user experience.

[0060] In an embodiment of the drying control method, the drying control method is applied to a clothes treatment device, and the drying control method comprises the following steps:

[0061] Step S10, starting the drying process of the clothes treatment device, and dynamically acquiring the running parameters of the clothes treatment device; the running parameters at least include one of the environmental temperature, the environmental humidity and the clothes weight in the drum;

[0062] For example, the drying control method is applied to the clothes drying control device of the clothes treatment device. After the user triggers the clothes drying function of the clothes treatment device, the drying process of the clothes treatment device is started, and the running parameters of the clothes treatment device are dynamically acquired in real time or every interval of the preset unit acquisition time. Figure 1

[0063] Optionally, the environmental temperature in the running parameters is the temperature of the air in the drum, which can be approximately represented by the temperature value sensed by the temperature sensor at the air outlet of the drum.

[0064] Optionally, the environmental humidity in the running parameters is the humidity of the air in the drum, which can be approximately represented by the humidity value sensed by the humidity sensor at the air outlet of the drum.

[0065] Optionally, the clothes weight in the running parameters is the total weight of the clothes in the drum, which can be obtained by converting the current value of the drum driving motor.

[0066] ​Step S20, according to the operation parameter, determining the first remaining time length required for the estimated drying of the clothes in the drum;

[0067] In an implementable manner, the step S20 of determining the first remaining time length required for the estimated drying of the clothes in the drum according to the operation parameter comprises:

[0068] Step S21, inputting the operation parameter into the pre-trained drying time length estimation model to determine the first remaining time length required for the estimated drying of the clothes in the drum.

[0069] For example, the drying time length estimation model can be a time estimation curve, and the first remaining time length can be preliminarily estimated by the pre-fitted time estimation curve. The time estimation curve is the time required for drying the clothes under ideal conditions (normal drum capacity and no winding). By inputting the operation parameter into the time estimation curve, the first remaining time length required for the estimated drying of the clothes under ideal conditions (normal drum capacity and no winding) can be more accurately estimated. Alternatively, the drying time length estimation model is a drying time length estimation curve formed by fitting a plurality of groups of data.

[0070] Alternatively, the operation parameter includes the ambient temperature, the ambient humidity and the weight of the clothes in the drum, and the determination of the first remaining time length and the second remaining time length is more accurate. That is, the present application can estimate the drying time required by the weight of the clothes and the ambient temperature or the weight of the clothes and the ambient humidity or the weight of the clothes, the ambient temperature and the ambient humidity, which is more accurate than estimating the drying time required by a single variable, and displaying the drying time (i.e. the first remaining time length) immediately after starting the drying program can improve the user experience.

[0071] Step S30, determining whether there is a target operation parameter in the operation parameter that meets the preset drying condition,

[0072] For example, when the operation parameter of the clothes treatment device meets the preset drying condition, it can be determined that the clothes have been dried with a high probability. When the target operation parameter meets the preset drying condition, it indicates that the clothes have been dried with a high probability based on the target operation parameter alone. At least the clothes have been dried substantially, or in other words, the clothes have been dried under ideal conditions (normal drum capacity and no winding) of the clothes treatment device.

[0073] Step S40, if there is a target operation parameter in the operation parameter, adjusting the first remaining time length to determine the second remaining time length; and when the second remaining time length of the drying process ends, closing the drying process.

[0074] After determining that there is a target running parameter in the determined running parameters that meets the preset drying condition, it is indicated that the clothes treatment equipment has been running for a long time, the clothes treatment equipment is in an ideal situation, the clothes have been dried, or the clothes are basically dried (at least the outside is dried), at this time, the first remaining time calculated before has a risk of inaccuracy, at this time, the first remaining time is adjusted and corrected to determine a second remaining time that is more suitable for the actual time required for drying the clothes, and when the second remaining time of the drying process ends, the drying process is closed. The dynamic running parameters reflecting the state of the clothes in the drum of the clothes treatment equipment and the actual working condition of the clothes treatment equipment are comprehensively considered, the first remaining time is corrected based on the dynamically obtained running parameters, the accuracy of the estimation of the clothes drying time is improved, and the user experience is improved.

[0075] Further, in another embodiment of the clothes drying control method of the present application, the step 30 of determining whether there is a target running parameter in the running parameters that meets the preset drying condition comprises:

[0076] Step S31, determining whether there is a target running parameter in the running parameters whose value is in the preset drying interval and whose value change rate is less than the preset threshold.

[0077] For example, the running parameters include the environmental temperature, the environmental humidity and the clothes weight in the drum, and whether the values of the environmental temperature, the environmental humidity and the clothes weight are respectively in the respective corresponding preset drying intervals and the respective value change rates are less than the preset threshold can be determined.

[0078] For example, the preset drying interval of the environmental temperature is an upper and lower temperature range of about 60 degrees Celsius, for example, the preset drying interval is 59 to 61 degrees Celsius, and the change rate of the environmental temperature is not obvious (tends to 0), which indicates that the temperature in the drum of the clothes treatment equipment is basically unchanged, the water vapor of the clothes has little or no influence on the change of the environmental temperature, the clothes are basically dried, and at least the outside of the clothes is basically dried.

[0079] For example, the preset drying interval of the environmental humidity is an upper and lower temperature range of about 3%, for example, the preset drying interval is 2% to 3%, and the change rate of the environmental humidity is not obvious (tends to 0), which indicates that the humidity in the drum of the clothes treatment equipment is basically unchanged, and there is little or no evaporation of water vapor of the clothes, the clothes are basically dried, and at least the outside of the clothes is basically dried.

[0080] For example, the preset drying interval of the clothes weight is a preset proportion range of the initial clothes weight, for example, the preset drying interval is 10 to 20% of the initial clothes weight, and the change rate of the clothes weight is not obvious (tends to 0), which indicates that the clothes weight in the drum of the clothes treatment equipment is basically unchanged, and there is little or no evaporation of water vapor of the clothes, the clothes are basically dried, and at least the outside of the clothes is basically dried.

[0081] In the embodiment, the target running parameter capable of triggering the current clothes drying judgment is determined by setting the preset drying interval corresponding to the value of each type of running parameter and the preset threshold with a small value change rate. The target running parameter with one or two values reaching the threshold range and with an unobvious change is determined by combining the preset drying interval and the value change rate, so as to facilitate subsequent accurate elimination of the target running parameter with little influence on the clothes drying judgment.

[0082] In some possible embodiments, the step of adjusting the first remaining duration in step S40 includes:

[0083] Step S41, the influence weight of the target running parameter on the remaining time required for the estimated drying of clothes is reduced;

[0084] After it is determined that there is the target running parameter with a value in the preset drying interval and a value change rate less than the preset threshold, it indicates that the target running parameter has no or basically no reference value for the drying time estimation, and other running parameters in the running parameters except the target running parameter have greater reference value for the drying time estimation. Therefore, the influence weight of the target running parameter on the remaining time required for the estimated drying of clothes is reduced, that is, the influence weight of other running parameters in the running parameters except the target running parameter on the remaining time required for the estimated drying of clothes is increased.

[0085] Exemplarily, the influence weight of the remaining time required for the estimated drying of clothes indicates the influence degree of a running parameter on the remaining time required for the drying of clothes. For example, the running parameters include the ambient temperature, the ambient humidity and the clothes weight, the initial influence weight of the ambient temperature is 40%, the initial influence weight of the ambient humidity is 30%, and the initial influence weight of the clothes weight is 30%. After the clothes treatment device starts to run the drying process, the ambient temperature is determined as the target running parameter, and then the influence weight of the ambient temperature is reduced from 40% to 10%, and the influence weights of the ambient humidity and the clothes weight are indirectly increased.

[0086] Step S42, determining the sub-remaining time required for drying clothes by each running parameter as a separate drying factor;

[0087] Exemplarily, each running parameter can be respectively and individually input into a pre-trained drying duration estimation model to determine the sub-remaining time required for drying clothes by each running parameter as a separate drying factor.

[0088] For example, continuing the above example, the operation parameters include ambient temperature, ambient humidity, and clothes weight, the influence weight of ambient temperature is 10%, the influence weight of ambient humidity is 30%, and the influence weight of clothes weight is 30%, and the ambient temperature, the ambient humidity, and the clothes weight are input into the drying time estimation model separately, and the sub-remaining time of the ambient temperature, the ambient humidity, and the clothes weight for drying clothes as separate drying factors is 3 minutes, 4 minutes, and 5 minutes, respectively.

[0089] In step S43, the second remaining duration is determined by weighted calculation according to the current influence weight and the sub-remaining time of each operation parameter.

[0090] For example, continuing the above example, the operation parameters include ambient temperature, ambient humidity, and clothes weight, the current influence weight of ambient temperature is 10%, the current influence weight of ambient humidity is 30%, and the current influence weight of clothes weight is 30%, and the sub-remaining time of the ambient temperature, the ambient humidity, and the clothes weight is 3 minutes, 4 minutes, and 5 minutes, respectively, and then the current influence weight and the sub-remaining time of each operation parameter are weighted calculated, that is, the second remaining duration = 10% * 3 + 30% * 4 + 30% * 5 = 3 minutes.

[0091] In the embodiment, by adjusting or redistributing the influence weight of each operation parameter (such as ambient temperature, ambient humidity, and clothes weight) on the determination of clothes drying, the influence weight of the target operation parameter is reduced by one or two values to reach the preset drying interval and the value change rate is less than the preset threshold (that is, the change is not obvious), the influence weight of other operation parameters except the target operation parameter is maintained or increased, the other operation parameters with a still large value change rate or not in the preset drying interval are valued, which is more in line with the actual situation that other operation parameters play a decisive role in the estimation of drying time, greatly improves the accuracy of the second remaining duration relative to the actual clothes drying time, and improves the user experience.

[0092] In some possible embodiments, the target operation parameter includes ambient temperature, and step S41 includes:

[0093] In step S411, when the ambient temperature is in the preset drying interval of the temperature and the value change rate of the ambient temperature is less than the preset threshold of the temperature, the influence weight of the ambient temperature on the remaining time required for the estimation of clothes drying is reduced.

[0094] For example, the target operating parameter includes the ambient temperature, i.e., the ambient temperature is in the preset drying interval of the temperature and the numerical change rate of the ambient temperature is less than the preset threshold of the temperature, in the current working condition of the clothes treatment, the ambient temperature has less influence on the estimated remaining time of the clothes drying, and other operating parameters are mainly used to determine the estimated remaining time of the clothes drying, thus the influence weight of the ambient temperature on the estimated remaining time of the clothes drying can be adjusted to be small, and the influence weight of other operating parameters on the estimated remaining time of the clothes drying can be adjusted to be large.

[0095] Optionally, the step of adjusting the influence weight of the ambient temperature on the estimated remaining time of the clothes drying to be small includes adjusting the influence weight of the ambient temperature on the estimated remaining time of the clothes drying to 0-10%. In this way, the influence weight of the ambient temperature as the target operating parameter is greatly adjusted to be small, and the accuracy of the second remaining time relative to the actual clothes drying time is increased.

[0096] For example, in the case that the air outlet of the air duct of the clothes treatment device is blocked or the lint filter is clogged, the ambient temperature in the drum is easily quickly raised to the numerical range of the preset drying interval of the temperature and the numerical change rate is less than the preset threshold of the temperature, at this time, the influence weight of the ambient temperature is reduced, and the ambient humidity and the clothes weight are mainly used to determine the estimated remaining time of the clothes drying.

[0097] In some possible embodiments, the target operating parameter includes the ambient humidity, the step S41 of adjusting the influence weight of the target operating parameter on the estimated remaining time of the clothes drying includes:

[0098] The step S412 of adjusting the influence weight of the ambient humidity on the estimated remaining time of the clothes drying to be small includes adjusting the influence weight of the ambient humidity on the estimated remaining time of the clothes drying to 0-10%.

[0099] For example, the target operating parameter includes the ambient humidity, i.e., the ambient humidity is in the preset drying interval of the humidity and the numerical change rate of the ambient humidity is less than the preset threshold of the humidity, in the current working condition of the clothes treatment, the ambient humidity has less influence on the estimated remaining time of the clothes drying, and other operating parameters are mainly used to determine the estimated remaining time of the clothes drying, thus the influence weight of the ambient humidity on the estimated remaining time of the clothes drying can be adjusted to be small, and the influence weight of other operating parameters on the estimated remaining time of the clothes drying can be adjusted to be large.

[0100] Optionally, the step of adjusting the influence weight of the ambient humidity on the estimated remaining time of the clothes drying to be small includes adjusting the influence weight of the ambient humidity on the estimated remaining time of the clothes drying to 0-10%. In this way, the influence weight of the ambient humidity as the target operating parameter is greatly adjusted to be small, and the accuracy of the second remaining time relative to the actual clothes drying time is increased.

[0101] For example, when the ambient humidity of the air in the drum of the clothes treatment apparatus is 3% or less and the change rate of the ambient humidity is small (e.g., less than a preset threshold of the humidity), it can be considered that the clothes have been dried, but when the clothes are wrapped (the clothes are dry on the outside and wet on the inside), the ambient humidity satisfies the drying judgment condition (e.g., is in a preset drying interval of the humidity and the numerical change rate of the ambient humidity is less than a preset threshold of the humidity) to stop, but the actual situation is that the inside of the clothes is not completely dry.

[0102] Therefore, it is necessary to make a comprehensive judgment in combination with the ambient temperature, the ambient humidity, or the weight of the clothes, but the conventional drying judgment method or algorithm cannot be applied to different working conditions. In the embodiments of the present application, the influence weight of the ambient temperature, the ambient humidity, or the weight of the clothes on the determination of the remaining time required for drying the clothes can be adjusted by detecting the operation parameters associated with the drying of the clothes. For example, when the clothes are wrapped, in the late drying stage, due to the clothes being dry on the outside and wet on the inside, the ambient temperature of the air in the drum basically reaches the drying stop condition (e.g., 60 degrees Celsius or 59 to 61 degrees Celsius) and the change rate of the temperature is not obvious (e.g., less than a preset threshold of the temperature), the ambient humidity also basically reaches the drying stop condition (e.g., 10% humidity or a humidity interval of 0% to 10%) and the change rate of the humidity is not obvious (e.g., less than a preset threshold of the humidity), but since the impact of the wrapped clothes on the drum is relatively large, the change rate of the weight of the clothes is relatively obvious (e.g., greater than a preset threshold of the weight of the clothes), therefore, the influence of the ambient temperature and the ambient humidity on the drying judgment is small, the influence on the remaining time required for drying the clothes is small, and whether the clothes are dry can be mainly determined by the change of the weight of the clothes, at this time, the influence weight of the ambient temperature and the ambient humidity on the drying judgment is adjusted to be low, and the influence weight of the weight of the clothes on the drying judgment is adjusted to be high, so as to realize accurate drying and make the second remaining time more suitable for the actual remaining time required for drying the clothes in the clothes treatment apparatus.

[0103] In some possible embodiments, the target operation parameter includes the weight of the clothes, and the step of adjusting the influence weight of the target operation parameter on the remaining time required for estimated drying of the clothes in step S41 includes:

[0104] In step S413, when the weight of the clothes is in a preset drying interval of the weight and the numerical change rate of the weight of the clothes is less than a preset threshold of the weight, the influence weight of the weight of the clothes on the remaining time required for estimated drying of the clothes is adjusted to be small.

[0105] For example, when the weight of the clothes is relatively light or the amount of the clothes is relatively small, the temperature in the drum of the clothes treatment apparatus can easily increase to reach the drying stop condition (e.g., the temperature in the drum is in the preset drying interval of the temperature and the rate of change of the temperature is less than the preset threshold of the temperature), and the weight of the clothes itself is relatively light and does not change significantly (e.g., the weight of the clothes is in the preset drying interval of the weight and the rate of change of the weight is less than the preset threshold of the weight). Therefore, in this state, the temperature in the drum and the weight of the clothes have less influence on the drying determination and the remaining time required for drying the clothes. The change in the humidity in the drum can be used to determine whether the clothes are dried. In this case, the influence weight of the temperature in the drum and the weight of the clothes on the drying determination is adjusted to be lower, and the influence weight of the humidity in the drum on the drying determination is adjusted to be higher, so that the clothes are accurately determined to be dried, and the second remaining time is more suitable for the actual remaining time required for drying the clothes in the clothes treatment apparatus.

[0106] Optionally, the step of adjusting the influence weight of the weight of the clothes on the second remaining time required for drying the clothes to be smaller includes adjusting the influence weight of the weight of the clothes on the second remaining time required for drying the clothes to be 0-10%. In this way, the influence weight of the weight of the clothes in the scenario of the target operating parameter is greatly reduced, and the accuracy of the second remaining time relative to the actual time required for drying the clothes is increased.

[0107] For example, when the weight of the clothes is relatively light or the amount of the clothes is relatively small, the temperature in the drum of the clothes treatment apparatus can easily increase to reach the drying stop condition (e.g., the temperature in the drum is in the preset drying interval of the temperature and the rate of change of the temperature is less than the preset threshold of the temperature), and the weight of the clothes itself is relatively light and does not change significantly (e.g., the weight of the clothes is in the preset drying interval of the weight and the rate of change of the weight is less than the preset threshold of the weight). Therefore, in this state, the temperature in the drum and the weight of the clothes have less influence on the drying determination and the remaining time required for drying the clothes. The change in the humidity in the drum can be used to determine whether the clothes are dried. In this case, the influence weight of the temperature in the drum and the weight of the clothes on the drying determination is adjusted to be lower, and the influence weight of the humidity in the drum on the drying determination is adjusted to be higher, so that the clothes are accurately determined to be dried, and the second remaining time is more suitable for the actual remaining time required for drying the clothes in the clothes treatment apparatus.

[0108] For example, the influence weights of the change rates of the temperature in the drum, the humidity in the drum, and the weight of the clothes on the drying time can also be obtained by querying a mapping table. Optionally, the preset thresholds corresponding to the change rates of the temperature in the drum, the humidity in the drum, and the weight of the clothes can be obtained by querying and determining a preset mapping table, which is more conducive to the determination of the calculation time of the second remaining time and the improvement of the accuracy of the value of the second remaining time relative to the actual drying condition.

[0109] Further, in another embodiment of the clothes drying control method, the clothes treatment apparatus further includes an internal-external circulation switching valve. Before the step of dynamically obtaining the operating parameters of the clothes treatment apparatus, the clothes drying control method further includes:

[0110] Step A: controlling the internal-external circulation switching valve to make the air circulation of the clothes treatment apparatus in an internal circulation state.

[0111] For example, when the weight of the clothes is relatively light or the amount of the clothes is relatively small, the temperature in the drum of the clothes treatment apparatus can easily increase to reach the drying stop condition (e.g., the temperature in the drum is in the preset drying interval of the temperature and the rate of change of the temperature is less than the preset threshold of the temperature), and the weight of the clothes itself is relatively light and does not change significantly (e.g., the weight of the clothes is in the preset drying interval of the weight and the rate of change of the weight is less than the preset threshold of the weight). Therefore, in this state, the temperature in the drum and the weight of the clothes have less influence on the drying determination and the remaining time required for drying the clothes. The change in the humidity in the drum can be used to determine whether the clothes are dried. In this case, the influence weight of the temperature in the drum and the weight of the clothes on the drying determination is adjusted to be lower, and the influence weight of the humidity in the drum on the drying determination is adjusted to be higher, so that the clothes are accurately determined to be dried, and the second remaining time is more suitable for the actual remaining time required for drying the clothes in the clothes treatment apparatus. Figure 3As shown, the inner-outer circulation switching valve 2 is in a closed state, closing the air inlet and air outlet of the air duct 3, and connecting the channel where the air inlet is located and the channel where the air outlet is located. In this embodiment, in order to prevent the air humidity of the external environment from affecting the detection of the environmental humidity of the clothes in the drum of the clothes treatment equipment, thereby affecting the influence weight of the environmental humidity of the clothes in the distribution drum, and ultimately affecting the drying detection and the second remaining time estimation, the switching valve is controlled to make the air duct of the clothes treatment equipment in an inner circulation state before the dynamic acquisition of the operating parameter, as shown. Figure 3

[0112] Further, in another embodiment of the clothes drying control method, the clothes drying control method further comprises:

[0113] After determining the first remaining time, output the first remaining time;

[0114] And / or, after determining the second remaining time, output the second remaining time.

[0115] For example, after the clothes treatment equipment starts the drying process, the operating parameter of the clothes treatment equipment is dynamically acquired, and the first remaining time of the drying program is calculated according to at least one of the clothes weight and the environmental temperature and the environmental humidity. After that, the first remaining time is displayed on the display panel of the clothes treatment equipment, or the first remaining time is announced by the speaker of the clothes treatment equipment, or the clothes treatment equipment sends the first remaining time to the binding terminal to remind the user. Optionally, the clothes treatment equipment generally needs to calculate the first remaining time and output it within a certain time, such as 30s, so that the user knows the time required for clothes drying in time, and the user experience of using the clothes treatment equipment is improved.

[0116] For example, after determining the second remaining time, the second remaining time can be displayed on the display panel of the clothes treatment equipment, or the second remaining time can be announced by the speaker of the clothes treatment equipment, or the clothes treatment equipment sends the second remaining time to the binding terminal to remind the user, so as to remind the user of the more accurate second remaining time in time and improve the user experience.

[0117] Further, in another embodiment of the clothes drying control method, before the step of adjusting the first remaining time and determining the second remaining time, the clothes drying control method further comprises:

[0118] Step B: counting the existing duration of the target operating parameter; when the existing duration is greater than a preset maximum duration, the step of adjusting the first remaining time and determining the second remaining time is performed.

[0119] ​For example, the existence duration of the statistical target operating parameter is: a duration that the statistical ambient temperature is in the preset drying interval of the temperature and the numerical change rate of the ambient temperature is less than the preset threshold of the temperature, a duration that the statistical ambient humidity is in the preset drying interval of the humidity and the numerical change rate of the ambient humidity is less than the preset threshold of the humidity, and a duration that the statistical clothes weight is in the preset drying interval of the weight and the numerical change rate of the clothes weight is less than the preset threshold of the weight. When the existence duration is greater than the preset maximum duration, the first remaining duration is adjusted, and the second remaining duration is determined. On the one hand, the output of the second remaining duration is not too short from the output of the first remaining duration, the user's prejudice that the remaining duration changes frequently and the remaining duration is inaccurate is avoided, and then the user's experience of using the clothes processing device is avoided. On the other hand, the first remaining duration is adjusted after the clothes processing device fully automatically processes special conditions (such as clothes unwinding), which is more conducive to accurate estimation of the second remaining duration.

[0120] For example, when the ambient humidity is less than 10%, the ambient temperature is higher than 50°C, and is maintained for 2 min, that is, in the later stage of drying the clothes by the clothes processing device, the first remaining duration is adjusted.

[0121] The present application also provides a clothes processing device, which comprises a drum, a drum driving motor, a memory, a processor, and a computer program stored on the memory and executable on the processor, and the computer program is configured to implement the steps of the clothes drying control method described above.

[0122] The present application also provides a computer readable storage medium, which stores a computer program, and the computer program is executed by a processor to implement the steps of the clothes drying control method described above.

[0123] The technical extension and technical effect derivation of the clothes processing device and the computer readable storage medium of the present application are basically the same as those of the above-mentioned clothes drying control method, and therefore will not be repeated.

[0124] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent processing scope of the present application.
