[0051] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions of other terms will be given in the description below. It should be noted that the concepts of "first", "second", etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the processes performed by these devices, modules or units.

[0053] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0054] The disclosed embodiment provides a control method for a clothing processing device. When it is detected that the real-time dryness of the load to be dried reaches the set dryness, the drying control temperature in the middle and late stages of drying is reduced, thereby reducing problems such as shrinkage and drying damage caused by excessive temperature of the load to be dried.

[0055] Before describing the control method of the drying device provided in the embodiment of the present disclosure, the structure of the clothing processing device provided in the embodiment of the present disclosure is first analyzed.

[0056] The clothing processing device is a device used to dry clothes and other loads that need to be dried, thereby drying the load to be dried. In a specific implementation, the clothing processing device can be a dedicated dryer or a washer-dryer that can have both washing and drying functions. In a specific implementation, the clothing processing device is mostly a drum dryer.

[0057] In a specific implementation, the clothes processing device can be a direct-discharge drying device or a condensing drying device. Considering that the condensing drying device can save energy and does not discharge hot air directly into the room, most clothes processing devices in actual applications are condensing drying devices.

[0058] In order to realize the drying function, the clothes processing device needs to be equipped with corresponding drying function components. In some embodiments, the clothes processing device is a heat pump drying device, including a fan, a heat pump system (including a heating component and a condensing dehumidification component), and a drying drum.

[0059] The fan is used to drive the air to circulate between the heating component, the drying drum and the condensing and dehumidifying component, so that the hot air heated by the heating component is blown into the drying drum to heat the load to be dried, and the hot air that has passed through the load to be dried is blown to the condensing and dehumidifying component, thereby realizing heat exchange between the air and the aforementioned various components and the load to be dried.

[0060] The heating component is a component used to heat the air flowing through it. The heating component can be an electric heating component such as a thermistor, or a condenser in a heat pump system, and the embodiments of the present disclosure do not specifically limit this. Because the heat pump system has a good energy-saving effect, and the evaporator configured therein can conveniently achieve condensation and dehumidification, the heating component in actual applications is mostly a condenser in a heat pump system.

[0061] The drying drum is a component used to carry the load to be dried, so that the hot air heated by the heating component contacts and exchanges heat with the load to be dried. In a specific implementation, the clothing processing device may also include a driving motor for driving the drying drum to rotate. The driving motor drives the drying drum to rotate, so that the load to be dried and the hot air are fully in contact, the heating area is increased, and the drying speed is accelerated. The hot air passing through the drying drum evaporates the moisture in the load to be dried, so that the hot air contains a large amount of water vapor.

[0062] The condensation and dehumidification component is a component used to cool the hot air that passes through the drying drum so that the water vapor in the hot air condenses and precipitates. By condensing the water vapor in the hot air, the water content in the air can be reduced and the dryness of the air can be increased, which is more conducive to the evaporation of water into the air in the subsequent drying load. In a specific implementation, the condensation and dehumidification component can be a water-cooled condensation and dehumidification component, or it can be an evaporator in a heat pump system. Considering that the evaporator can also transfer heat to the refrigerant, the heat can be released at the condenser after the compressor compresses the refrigerant. In a specific implementation, the condensation and dehumidification component preferably uses an evaporator in a heat pump system.

[0063] Figure 1 is a flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure. Figure 1 As shown, the control method of the clothing processing device provided in the embodiment of the present disclosure includes S110-S120.

[0064] S110: In the process of drying the load to be dried according to the first drying control temperature control, detecting the real-time dryness of the load to be dried.

[0065] In the disclosed embodiment, after the drying program is started, the clothing processing device can determine the first drying control temperature for drying the clothing according to parameters such as the drying mode set by the user and the weight of the load to be dried, and control the drying operation of the load to be dried according to the first drying control temperature.

[0066] The aforementioned first drying control temperature is a parameter used to control the working characteristics of the heating component. In a specific implementation, the first drying control temperature may be a parameter for controlling the hot air temperature at the hot air outlet of the heating component and the temperature at the air inlet of the drying drum of the clothing processing device. If the hot air temperature at the hot air outlet of the heating component is lower than the first drying control temperature, the clothing processing device controls the heating component to increase the temperature of the hot air at the hot air outlet. If the hot air temperature at the hot air outlet of the heating component is higher than the first drying control temperature, the clothing processing device controls the heating component to cool down and reduce the hot air temperature at the hot air outlet.

[0067] In some embodiments, when the clothes processing device starts the drying operation of the load to be dried, it can adjust the first drying control temperature in time according to the progress of the drying operation. For example, when the clothes processing device is just started, the temperature of the load to be dried is 20°C, and the first drying control temperature can be set to 30°C; and when the temperature of the load to be dried reaches 25°C, the first drying control temperature is adjusted to 35°C. That is to say, in some embodiments, the clothes processing device can gradually increase the first drying control temperature according to the temperature rise of the load to be dried until it reaches a specific temperature value, and the first drying control temperature is not a fixed temperature.

[0068] In other embodiments, the first drying control temperature may also be set to a fixed temperature, for example, directly set to 60°C.

[0069] In order to determine whether the load to be dried has been dried according to the actual situation, a sensor for detecting the real-time dryness of the load to be dried is arranged in the drying drum of the clothes processing device. During the process of the clothes processing device drying the load to be dried, the sensor monitors and senses in real time to determine the real-time dryness of the load to be dried. In a specific implementation, considering that the load to be dried has a lot of moisture at the beginning of drying, and the drying process at the beginning is mainly to heat up the load to be dried and the drying drum, and the moisture in the load to be dried has not yet evaporated, the clothes processing device can detect the real-time dryness after the load to be dried has been dried for a period of time.

[0070] It should be noted that the real-time dryness mentioned in the embodiments of the present disclosure refers to the dryness of the load that needs to be dried at the moment of monitoring and sensing.

[0071] In a specific implementation, the aforementioned sensor may be a humidity sensor or a temperature sensor. In the case where the sensor is a temperature sensor, after acquiring the temperature data detected by the temperature sensor, the clothing processing device may determine the temperature change data according to the temperature data detected nearby. After determining the temperature change data, the clothing processing device may directly or indirectly determine the real-time dryness of the load.

[0072] S120: Determine that the real-time dryness is greater than the first dryness, and continue to control the drying operation of the load to be dried according to the second drying control temperature, wherein the second drying control temperature is lower than the first drying control temperature.

[0073] In the disclosed embodiment, when it is determined that the real-time dryness of the load to be dried has reached a first dryness, the clothing processing device no longer uses the first drying control temperature to continue to control the drying operation of the load to be dried, but uses a second drying control temperature that is lower than the first drying control temperature to continue to control the drying operation of the load to be dried.

[0074] As analyzed above, the real-time dryness detected by the clothing processing device can be represented by temperature change data. Correspondingly, the first dryness can also be represented by temperature change data. To determine whether the implemented dryness is greater than the first dryness, it can be to compare the actual detected temperature change data to see whether it is greater than the temperature change data corresponding to the first dryness. If the actual temperature change data is greater than the temperature change data corresponding to the first dryness, it is determined that the real-time dryness is greater than the first dryness.

[0075] In the disclosed embodiment, a second drying control temperature is used to control the drying operation of the load to be dried. The second drying control temperature can also be used as the hot air temperature at the hot air outlet of the heating component or the temperature of the air inlet of the drying drum, so that hot air with a temperature substantially equal to the second drying control temperature is blown toward the load to be dried, thereby achieving further drying processing of the load to be dried.

[0076] The following is an analysis of the effects that can be achieved by using the aforementioned S110-S120 and the reasons why the aforementioned effects can be achieved.

[0077] First of all, it should be made clear that the clothing processing equipment uses hot air to blow toward the load to be dried, so that the free water in the load to be dried absorbs heat and evaporates, thereby drying the load to be dried. According to the principle of heat conduction, under normal conditions, heat is conducted from a high-temperature object to a low-temperature object. In order to make the free water in the load to be dried continue to absorb heat and evaporate, the temperature of the hot air blown toward the load to be dried needs to be higher than the temperature of the load to be dried. In order to speed up the drying speed, the temperature of the hot air blown toward the load to be dried should be increased as much as possible within a safe range, that is, the first drying control temperature should be as high as possible. The first drying control temperature may be close to or even higher than the safety temperature corresponding to the material of the load to be dried.

[0078] During the drying operation of the clothes treatment device, as the drying operation continues, the free water in the load to be dried gradually absorbs heat and evaporates, and the water content of the load to be dried gradually decreases. As the free water in the load to be dried gradually decreases, the overall weight of the load to be dried decreases, and the ability to resist the increase in its own temperature through the free water absorbing heat and evaporating also weakens.

[0079] If the temperature is still controlled according to the first drying control temperature initially set, the load to be dried will increase rapidly after the free water content in the load to be dried is lower than a specific ratio, that is, after the real-time dryness of the load to be dried is greater than a specific dryness. As the temperature of the load to be dried increases, the free water in the load to be dried will further accelerate evaporation and decrease, causing the load to be dried to enter the critical temperature and humidity range. After entering the critical temperature and humidity range, the temperature of the load to be dried will quickly approach the first drying control temperature. As the temperature of the load to be dried gradually approaches the first drying control temperature, its material will also degenerate due to the high temperature, resulting in shrinkage or even damage.

[0080] It has been discovered that the use of the aforementioned first drying control temperature to control the drying operation of the load to be dried will cause the temperature of the load to be dried to rise rapidly in the later stage of drying, resulting in the risk of the load to be dried being damaged by high temperature. In the embodiment of the present disclosure, when the load to be dried is dried according to the first drying control temperature, the real-time dryness of the load to be dried is detected. When it is determined that the real-time dryness has reached a dryness greater than the first dryness, a second drying control temperature less than the first drying control temperature is used to continue to control the drying operation of the load to be dried, thereby reducing the risk of the load to be dried being damaged.

[0081] As analyzed above, when it is determined that the implemented dryness is greater than the first dryness, the drying operation of the load to be dried is continued to be controlled according to the second drying control temperature. In practical applications, it is necessary to reasonably set the second drying control temperature to avoid the risk of a high probability of damaging the clothes when the load to be dried is dried according to the second drying control temperature.

[0082] It should be noted here that the second drying control temperature mentioned in the embodiment of the present disclosure should be understood in an expanded sense. In some applications, the second drying control temperature is a constant value, that is, the second drying control temperature is a temperature that remains unchanged; while in other applications, the second drying control temperature is not a constant value, but a variable value. Considering that the closer to the end of drying, the lower the drying control temperature needs to be. In the case where the second drying control temperature is a variable value, the second drying control temperature gradually decreases from a specific value as the drying proceeds.

[0083] In some embodiments of the present disclosure, the clothes processing device can directly use the drying temperature used in the low-temperature drying mode as the second drying control temperature, and continue to control the drying operation of the load to be dried in the low-temperature drying mode. In other embodiments of the present disclosure, the clothes processing device can also determine the second drying control temperature according to the actual situation of the load to be dried.

[0084] In some other embodiments of the present disclosure, the clothes processing device may estimate a target control temperature for keeping the temperature of the load to be dried from rising while continuing the drying process, and use the aforementioned target control temperature as the second drying control temperature.

[0085] In a specific implementation, the clothing processing device may use the control temperature that prevents the temperature of the load to be dried from rising as the intermediate control temperature, so that the load to be dried will not be damaged due to the temperature rise. In a specific implementation, the aforementioned preventing the temperature of the load to be dried from rising includes two situations: (1) maintaining the temperature of the load to be dried at the previous temperature, that is, the temperature of the load to be dried remains basically unchanged, with only slight fluctuations; for example, if the temperature of the load to be dried is 85°C when the real-time dryness of the load to be dried is detected to be greater than the first dryness, then the temperature of the load to be dried is subsequently maintained at 85°C. (2) maintaining the temperature of the load to be dried lower than the previous temperature; for example, if the temperature of the load to be dried is 85°C when the real-time dryness of the load to be dried is detected to be greater than the first dryness, then the temperature of the load to be dried is subsequently maintained at lower than 85°C.

[0086] The aforementioned process of making the temperature of the load to be dried lower than the previous temperature can be divided into two cases: (1) maintaining the temperature of the load to be dried at a specific value lower than the previous temperature; for example, if the real-time dryness of the load to be dried is greater than the first dryness when the load is detected to be dried, the temperature of the load to be dried is 85°C, and then during the drying process, the temperature of the load to be dried is reduced to 80°C and maintained; (2) gradually reducing the temperature of the load to be dried. For example, if the real-time dryness of the load to be dried is greater than the first dryness when the load is detected to be dried, the temperature of the load to be dried is 85°C, and then during the drying process, the temperature of the load to be dried is gradually reduced from 85°C until it reaches 30°C.

[0087] According to the law of conservation of heat, the reason why the humidity and temperature of the load to be dried present the aforementioned changes is not only the hot air controlled according to the first drying control temperature, but also the evaporation rate of free water in the load to be dried. Based on the real-time dryness detected during the drying process and the real-time temperature of the load to be dried, combined with the drying heating power corresponding to the current drying control temperature, the evaporation rate and evaporation amount of the water in the load to be dried can be calculated. Since the water content ratio of the load to be dried is basically determined (excess water does not remain in the fabric gaps of the load to be dried, but will be lost under the action of gravity), combined with the aforementioned water evaporation rate and evaporation amount, the water evaporation rate and evaporation amount that keep the temperature of the load to be dried at the target temperature can be estimated. According to the aforementioned water evaporation rate and evaporation amount, the required drying heating power can be estimated. Then, the intermediate drying control temperature can be determined according to the drying heating power and the flow rate of the hot air.

[0088] It should be noted that when the aforementioned target control temperature is used as the second drying control temperature to control the drying of the load to be dried, due to system errors or accidental errors such as detection delays or inaccurate predictions, the actual temperature of the load to be dried may be slightly higher than the previous temperature in some periods of time, but the aforementioned period will not be particularly long.

[0089] In some other embodiments of the present disclosure, the clothes processing device can determine the second drying control temperature according to the initial load of the load to be dried. In the embodiment of the present disclosure, the second drying control temperature is positively correlated with the initial load, and the larger the initial load, the larger the corresponding initial drying control temperature.

[0090] It should be noted that the positive correlation between the second drying control temperature and the initial load is a positive correlation within a specific temperature range, and the second drying control temperature will not be higher than the first drying control temperature.

[0091] It should also be noted that the positive correlation between the second drying control temperature and the initial load may be a linear positive correlation or a nonlinear positive correlation. The aforementioned nonlinear positive correlation may be a step function positive correlation, a quadratic function positive correlation, and the like.

[0092] In some embodiments, the laundry processing apparatus may determine the second drying control temperature according to the initial load using the following S210-S230. The following S210-S230 is essentially a method for determining the second drying control temperature using a step function positive correlation.

[0093] S210: Compare whether the initial load is greater than or equal to a first load threshold; if not, execute S220; if so, execute S230.

[0094] S220: Using the first temperature as the second drying control temperature.

[0095] S230: Using the second temperature as the second drying control temperature.

[0096] The first temperature and the second temperature are both pre-set temperatures that are lower than the first drying control temperature, and the first temperature is lower than the second temperature. In a specific implementation, the first temperature and the second temperature are both determined through drying experimental tests.

[0097] The first load threshold is a pre-set threshold used to determine the initial load level. The first load threshold can be set based on experiments. How to determine the first load threshold through experiments will be described later.

[0098] By comparing the initial load and the first load threshold, it can be determined whether the load to be dried is small. If the initial load is less than the first load threshold, it is determined that the initial load is small. If the initial load is greater than or equal to the first load threshold, it is determined that the initial load is not too small.

[0099] Since the moisture content of the load to be dried is generally determined, the moisture content of the load to be dried can also be generally determined when the initial load is determined. When the real-time dryness is determined to be equal to the first dryness, the moisture content of the load to be dried is also generally determined.

[0100] According to the above reasoning, if the initial load is less than the first load threshold, it can be determined that when the real-time dryness is detected to be greater than the first dryness, the water content of the load to be dried is also less. In order to avoid the rapid temperature rise of the load to be dried due to the rapid evaporation of water in the subsequent drying process, the first temperature can be used as the second drying control temperature. On the contrary, if the initial load is greater than or equal to the first load threshold, when the real-time dryness is detected to be greater than the first dryness, the water content of the load to be dried is relatively high, and the second temperature can be used as the second drying control temperature.

[0101] In some other embodiments, the clothes treating apparatus may determine the second drying control temperature in S240 as follows.

[0102] S240: Processing the initial load or the real-time load according to the drying temperature adjustment function to obtain a second drying control temperature.

[0103] The drying temperature adjustment function is a predetermined function that characterizes the positive correlation between the initial load and the second drying control temperature. The drying temperature adjustment function can be the aforementioned quadratic function, linear function, etc. It should be noted that the drying temperature adjustment function is a function that characterizes the positive correlation between the load and the initial drying control temperature. After determining the initial load, the initial load is input into the drying temperature adjustment function, and the corresponding second drying control temperature can be obtained. When the second drying control temperature is determined using the drying temperature adjustment function, different initial loads can correspond to different second drying control temperatures.

[0104] In the above embodiments, it is mentioned that the second drying control temperature is determined by using the initial load of the load to be dried. Determining the initial load of the load to be dried is a prerequisite for determining the second drying control temperature. In specific implementations, the clothing processing device can determine the initial load of the load to be dried in various ways.

[0105] In some embodiments, the clothing processing device can control the driving motor to drive the drying drum to rotate according to the set power, and detect the motion characteristic parameters in the drying drum, and then determine the initial load amount of the load to be dried according to the motion characteristic parameters in the drying drum.

[0106] The kinematic characteristic parameter is a parameter used to characterize the kinematic characteristics of a specific object, and the kinematic characteristic parameter may include motion speed, motion angular velocity, motion acceleration or motion angular acceleration. In the embodiment of the present disclosure, the kinematic characteristic parameter is preferably the motion angular velocity or motion angular acceleration of the drying drum.

[0107] According to the principle of kinematics, under the drive of a specific input power, the kinematic characteristic parameters that can be achieved by the drying drum are different at different initial load amounts of the load to be dried. Accordingly, the initial load amount of the load to be dried can be determined based on the kinematic characteristic parameters detected during the rotation of the clothing processing device. For example, in some embodiments, the clothing processing device pre-stores an association relationship table of kinematic characteristic parameters and initial load weight under a specific input power. After the motion characteristic parameters of the drying drum are detected, the association relationship table is searched based on the motion characteristic parameters to determine the initial weight of the load to be dried, and the aforementioned initial weight is used as the initial load amount of the load to be dried.

[0108] It should be noted that, because the load to be dried itself is not a rigid body, and the load to be dried is not rigidly connected to the clothing processing drum, during the rotation of the clothing processing equipment, the load to be dried will slide relative to the drying drum, and relative sliding will also occur inside the load to be dried. The load weight determined based on the aforementioned first kinematic characteristic parameter is only an initial estimated weight, not an accurate weight.

[0109] In some other embodiments, the clothes processing device can perform a pre-drying operation on the load to be dried according to a preset heating power, so that the load to be dried can be quickly heated up, thereby increasing the kinetic energy of evaporation of water in the clothes. When the heating power during the pre-drying operation is determined, the heating rate during the pre-drying operation on the load to be dried is inversely proportional to the weight of the load to be dried (assuming that the specific heat capacity of the clothes is the same). Therefore, the initial load amount of the load to be dried can be determined according to the heating rate.

[0110] In some embodiments, the clothes processing device stores a correlation table of the heating rate and the initial load under a specific heating power. The corresponding relationship between the heating rate and the initial load in the correlation table is determined according to experiments. After determining the heating rate, the control device retrieves the correlation table based on the heating rate to determine the initial load of the load to be dried.

[0111] Of course, the aforementioned method for determining the initial load amount can also be used to determine the real-time load amount of the load to be dried, that is, to determine the load amount of the load to be dried during the drying operation.

[0112] As mentioned above, based on the initial load of the load to be dried, the second drying control temperature is determined by a corresponding processing method. Considering that the real-time dryness of the load to be dried can be detected at each moment, the real-time dryness is related to the amount of residual water in the load to be dried. According to the real-time dryness and the real-time load of the load to be dried, the amount of residual water in the load to be dried can be roughly estimated. The purpose of setting the second drying control temperature is to remove the residual water in the load to be dried. Therefore, the second drying control temperature can also be determined based on the real-time load of the load to be dried by the processing method mentioned above.

[0113] Figure 2 FIG. 1 is a flow chart of a control method for a clothes processing device provided by another embodiment of the present disclosure. Figure 2 As shown, in some other embodiments of the present disclosure, the control method of the clothing processing device includes S310-S340.

[0114] S310: In the process of performing a drying operation on the load to be dried according to the first drying control temperature control, detecting the real-time dryness of the load to be dried.

[0115] S320: Determine whether the real-time dryness is greater than the first dryness; if so, execute S330 and S340; if not, continue to execute S310.

[0116] S330: Continue to control the drying operation of the load to be dried according to the second drying control temperature, wherein the second drying control temperature is lower than the first drying control temperature.

[0117] S340: Controlling the drying drum of the clothes processing apparatus to continue rotating according to the first rotation control parameter.

[0118] The specific execution process of S310-S330 is the same as the execution process of S110-S120 mentioned above, which will not be repeated here. For details, please refer to the above description. Different from the above embodiment, when the drying operation of the load to be dried is continued to be controlled according to the second drying control temperature, the clothes processing device will also control the drying drum of the clothes processing device to continue to rotate according to the first rotation control parameter.

[0119] In the disclosed embodiment, during the drying operation of the load to be dried according to the first drying control temperature control, the clothes processing device will also control the rotation of the drying drum of the clothes processing device according to the second rotation control parameter to increase the heat exchange area between the load to be dried and the hot air, thereby accelerating the drying speed. After determining that the implemented dryness is greater than the first dryness, the clothes processing device no longer uses the second rotation control parameter to control the drying drum to continue rotating, but uses the first rotation control parameter to control the drying drum to continue rotating.

[0120] The first rotation control parameter includes a first rotation speed and a first rotation-stop ratio, and the second rotation control parameter includes a second rotation speed and a second rotation-stop ratio. In the disclosed embodiment, the first rotation speed is less than the second rotation speed, and the first rotation-stop ratio is less than the second rotation-stop ratio.

[0121] As analyzed above, during the clothes drying process, by controlling the drying drum to rotate at a specific speed and start-stop ratio, the load to be dried is caused to roll and fall, which can increase the contact area between the load to be dried and the hot air, thereby speeding up the drying speed.

[0122] In the early stage of drying, since the moisture content of the load to be dried is relatively high, its wrinkles have not yet taken shape. At this time, a relatively large rotation speed and stop ratio can be used to control the rotation of the drying drum, so that the load to be dried will roll and fall significantly, which will not have a significant impact on the wrinkles. In the later stage of drying, since the moisture content of the load to be dried is relatively low, large-scale rolling and falling during the drying process will cause wrinkles in the load to be dried, and as the moisture content of the load to be dried further decreases, the aforementioned wrinkles will gradually take shape. At this time, in order to reduce the wrinkles caused by rolling and falling of the load to be dried, it is necessary to reduce the rotation speed and stop ratio.

[0123] In the embodiment of the present disclosure, when it is determined that the real-time dryness is greater than the first dryness, the moisture content of the load to be dried is already low, and by adjusting the rotation control parameter for controlling the rotation of the drying drum from the second rotation control parameter to the first rotation control parameter, that is, adjusting the second rotation speed to the first rotation speed, and adjusting the second stop ratio to the first stop ratio, the rolling and falling of the load to be dried in the later stage of drying can be reduced, thereby reducing the wrinkles caused thereby.

[0124] As analyzed above, when it is determined that the real-time dryness is greater than the first dryness, the drying drum of the laundry processing device is controlled to continue rotating according to the first rotation control parameter. The premise of controlling the drying drum to continue rotating according to the first rotation control parameter is to determine the first rotation control parameter. In the disclosed embodiment, before executing the aforementioned S340, the laundry processing device may execute the following S350 to determine the first rotation control parameter.

[0125] S350: Determine a first rotation control parameter according to an initial load or a real-time load of the load to be dried.

[0126] In a specific implementation, the speed and the stop ratio required to enable the load to be dried to fully rotate are different according to the different load amounts of the load to be dried in the drying drum. Based on the above relationship, the embodiment of the present disclosure determines the first rotation control parameter according to the initial load amount or the real-time load amount of the load to be dried, that is, determines the first rotation speed and the first stop ratio according to the initial load amount or the real-time load amount.

[0127] In a specific implementation, the aforementioned S350 determining the first rotation control parameter according to the initial load amount of the load to be dried may include the following S351-S352.

[0128] S351: Determine whether the initial load is greater than the second load threshold; if not, execute S352; if so, execute S353.

[0129] S352: Using the first control speed and the first control rotation-stop ratio as the first rotation control parameter.

[0130] S353: The first multi-combination cycle speed and the second control start-stop ratio are used as the first rotation control parameter.

[0131] In actual applications, if the load to be dried is small, it is only necessary to control the drying drum of the clothing processing equipment to rotate at a specific rotation speed, so that the load to be dried can be fully unfolded and all parts can be fully in contact with the hot air; if the drying load is large, the load to be dried maintains a specific shape when rotating at a specific rotation speed, and the internal relative position does not change much, and the inner part cannot be fully in contact with the hot air.

[0132] Based on the above analysis, in the embodiment of the present disclosure, when the clothes processing device determines that the initial load of the load to be dried is less than the second load threshold, a specific first control speed and a first control turn-stop ratio are used as the first rotation control parameter. If the clothes processing device determines that the initial load of the load to be dried is greater than or equal to the second load threshold, in order to avoid the load shape remaining unchanged during the rotation process, the first multi-combination cycle rotation speed and the second turn-stop control ratio are used as the first rotation control parameter. The aforementioned first multi-combination cycle rotation speed is a rotation speed formed by combining at least two preset rotation speeds and executed cyclically.

[0133] As analyzed above, before drying the load to be dried according to the second drying control temperature, the load to be dried needs to be dried according to the first drying control temperature. Reasonable determination of the first drying control temperature has an important influence on improving the drying rate. The following is an analysis of how to determine the first drying control temperature.

[0134] In the embodiment of the present disclosure, the clothes processing apparatus may determine the first drying control temperature using the following S410-420.

[0135] S410: Detecting the initial load amount of the load to be dried.

[0136] For details on how to determine the initial load amount to be dried, please refer to the previous analysis and will not be repeated here.

[0137] S420: Determine a first drying control temperature according to an initial load amount of the load to be dried, wherein the first drying control temperature is positively correlated with the initial load amount.

[0138] After determining the initial load, the clothes processing device can determine the first drying control temperature according to the initial load. In the embodiment of the present disclosure, the first drying control temperature is positively correlated with the initial load, that is, the larger the initial load, the larger the corresponding first drying control temperature. That is, if the initial load is small, the clothes processing device will adopt a smaller first drying control temperature. If the initial load is large, the clothes processing device will adopt a larger first drying control temperature.

[0139] Similar to the positive correlation between the second drying control temperature and the initial load in the previous text, the positive correlation between the first drying control temperature and the initial load is a positive correlation within a specific temperature range, and the value of the first drying control temperature will not exceed the pre-set safe drying range. The first drying control temperature and the initial load are positively correlated, which can be a linear positive correlation or a nonlinear positive correlation. The aforementioned nonlinear positive correlation can be a step function positive correlation, a quadratic function positive correlation, etc.

[0140] In some embodiments, the laundry processing device may determine the first drying control temperature using the following steps S421-S423: The following steps S421-S423 are substantially a method for determining the first drying control temperature using a step function positive correlation.

[0141] S421: Compare whether the initial load is greater than or equal to a third load threshold; if so, execute S422; if not, execute S423.

[0142] S422: Using the third temperature as the first drying control temperature.

[0143] S423: Using the fourth temperature as the first drying control temperature.

[0144] The third load threshold is a pre-set threshold used to determine the initial load level. The third load threshold is set based on experiments.

[0145] If the initial load is less than the first load threshold, it is determined that the initial load is small, so the third temperature is used as the first drying control temperature. If the initial load is greater than or equal to the first load threshold, it is determined that the initial load is not too small, and the fourth temperature is used as the first drying control temperature. Here, it should be noted that the third temperature is less than the fourth temperature.

[0146] The first drying control temperature is determined by comparing the initial load and the third load threshold. In other embodiments, multiple load thresholds can be set in the clothing processing device, and adjacent load thresholds correspond to a specific control temperature, and the control temperature corresponding to the load interval determined by the smaller load threshold is smaller than the load interval determined by the larger load threshold. Accordingly, after determining the initial load, the initial load is compared with each load threshold, and after determining the corresponding control temperature, the corresponding control temperature can be used as the first drying control temperature.

[0147] In some other embodiments, the clothes treating apparatus may determine the first drying control temperature in S424 as follows.

[0148] S424: using the initial drying temperature determination function to process the initial load to obtain a first drying control temperature.

[0149] The initial drying temperature determination function is a predetermined function that characterizes the positive correlation between the initial load and the first drying control temperature. Similar to the drying temperature adjustment function described above, the initial drying temperature determination function may be the aforementioned quadratic function, linear function, etc. When the initial drying temperature determination function is used to determine the first drying control temperature, different initial loads may correspond to different first drying control temperatures.

[0150] The general inherent thinking is that the higher the initial drying control temperature of the clothing processing equipment, the faster the corresponding drying load speed, especially when the load to be dried is a small amount of small clothes, the higher the drying control temperature, the shorter the drying time. However, after a more detailed analysis of the reasons for energy consumption and time consumption in the drying process, the applicant found that the above inherent thinking does not hold true under some conditions.

[0151] Generally, the drying process includes a heating and drying process and a cooling process. In the heating and drying process, not only the load to be dried is heated, but also the bearing components such as the drying drum of the clothing processing equipment are heated. It also takes time to heat the bearing components such as the drying drum. Moreover, the higher the drying control temperature, the longer it takes to heat the aforementioned bearing components to the corresponding specific temperature and maintain the temperature stable. Similarly, the cooling process requires not only cooling the load to be dried, but also cooling the bearing components such as the drying drum of the clothing processing equipment. The higher the drying control temperature during the heating and drying process, the more time it takes to cool down the bearing components accordingly. When the load to be dried is small, the time required to heat and lower the drying drum for the bearing components accounts for a large proportion. In this case, it is not that the higher the temperature, the shorter the time required for drying; on the contrary, when the load to be dried is small, the drying control temperature is set lower, and the time required for drying will be shorter.

[0152] Based on the above analysis, the embodiment of the present disclosure proposes to determine the initial load amount of the load to be dried, determine the positively correlated first drying control temperature according to the initial load amount, and then perform a drying operation on the load to be dried according to the first drying control temperature. By adopting the scheme provided by the embodiment of the present disclosure, when the initial load amount is small, compared with adopting the set larger first drying control temperature, adopting the corresponding smaller first drying control temperature can realize the drying operation of the load in a shorter time, and the drying energy consumption is also reduced accordingly.

[0153] As analyzed above, when the drying operation is performed on the load to be dried according to the first drying control temperature control, in order to increase the drying rate, it is also necessary to control the rotation of the drying drum. In the disclosed embodiment, the clothing processing device controls the rotation of the drying drum according to the second drying control parameter, and the second rotation control parameter includes a second rotation speed and a second start-stop ratio.

[0154] In the disclosed embodiment, the laundry processing apparatus may determine the second rotation control parameter in S430 as follows.

[0155] S430: Determine a second rotation control parameter of a drying drum in the laundry processing device according to the initial load amount.

[0156] In a specific implementation, the aforementioned S430 may include the following S431 - S433 .

[0157] S431: Compare whether the initial load is less than or equal to a fourth load threshold; if so, execute S432; if not, execute S433.

[0158] S432: The target rotation speed that makes the beating path of the load to be dried the longest is used as the second rotation speed.

[0159] S433: The second multi-combination cycle speed is used as the second rotation speed.

[0160] The fourth load threshold is a pre-set threshold for determining the initial load level. The fourth load threshold can be set based on experiments. In specific implementations, the load to be dried and the first rotation speed can be changed while the first drying control temperature remains unchanged, and the drying time under various conditions is determined and plotted to determine the first rotation speed.

[0161] Through experimental tests, it is found that when the initial load is less than the fourth load threshold, the rotation speed that makes the drying time shortest is the target rotation speed that makes the path of the load to be dried longest, so the target rotation speed can be used as the second rotation speed. When the initial load is greater than the fourth load threshold, the second multi-combination cycle rotation speed is used as the second rotation speed, which makes the drying time shortest. The second multi-combination cycle rotation speed is also a rotation speed formed by combining at least two preset rotation speeds and executed cyclically.

[0162] As analyzed above, the target rotation speed is the rotation speed that makes the drying load's beating path the longest. When the initial load of the drying load is small, using the target rotation speed as the second rotation speed can make the drying load be fully beaten and developed, increasing its contact area with the hot air.

[0163] In some specific embodiments, the laundry processing device may determine the target rotation speed according to the initial load by kinematic simulation estimation. The kinematic simulation estimation method is specifically to input the initial load into a pre-built rotation speed determination model to obtain the target rotation speed.

[0164] In some other embodiments, it has been verified through experiments that when the weight of the load to be dried in the clothes processing device is less than the second load threshold, the load can be fully unfolded and the beating path can basically reach the longest when it is required to rotate according to the preset empirical speed, so the preset empirical speed can be used as the target rotation speed. For example, the speed in the range of 40-50rmp can be used as the target rotation speed.

[0165] When the initial load of the load to be dried is greater than the fourth load threshold, because the load to be dried is large, when the load is driven to rotate according to the target rotation speed, the load to be dried will maintain a specific rotation shape, and the internal relative position relationship will not change. To avoid this problem, the clothing processing device can use the second preset cycle speed as the second rotation speed.

[0166] In order to use the multi-combination cycle speed as the second rotation speed, in a specific implementation, the laundry processing device selects two combinations from a plurality of preset speeds to form a multi-combination cycle speed. The aforementioned preset speeds include at least one low speed, at least one intermediate speed, and at least one high speed. For example, in one application, the preset speeds include low speeds of 30-50rpm and 50rmp-60rpm, the intermediate speed includes 60rmp-70rpm, and the high speed includes a combination of 80rmp-90rpm. The control device can combine all the aforementioned preset speeds into a multi-combination cycle speed.

[0167] In the disclosed embodiment, while the clothes processing device continues to control the drying operation of the load to be dried according to the second drying control temperature, the clothes processing device can continue to detect the real-time dryness of the load to be dried. When it is determined that the real-time dryness is greater than the second dryness, it is determined that the load to be dried is basically dry, and then the load to be dried can be cooled to reduce the temperature of the load to be dried and the clothes processing device, thereby preventing the user from being burned when removing the dried load. It should be noted that the aforementioned second dryness is greater than the first dryness.

[0168] In a specific implementation, while cooling the load to be dried, the clothing processing device can continue to control the rotation of the drying drum according to the first rotation control parameter, or control the drying drum to continue rotating at a second rotation speed slower than the first drying control parameter to speed up the cooling of the load.

[0169] After the cooling operation is completed, it can be determined that the drying operation on the load is finished. At this time, the clothes processing device can end the drying and alarm through a buzzer.

[0170] In addition to providing the aforementioned drying control method for the clothes treating apparatus, the embodiment of the present disclosure also provides a control device for the clothes treating apparatus.

[0171] The dryness detection unit 301 is used to detect the real-time dryness of the load to be dried during the process of performing a drying operation on the load to be dried according to the first drying control temperature control.

[0172] The control unit 302 is used to continue controlling the drying operation of the load to be dried according to the second drying control temperature when the dryness detection unit 301 determines that the real-time dryness is greater than the first dryness, wherein the second drying control temperature is lower than the first drying control temperature.

[0173] In some embodiments, the control device 300 of the clothing processing equipment also includes a temperature setting unit, which is used to estimate a target control temperature for keeping the temperature of the load to be dried from rising during the continued drying process, and use the target control temperature as the second drying control temperature; or, determine the second drying control temperature based on the initial load or real-time load of the load to be dried, and the second drying control temperature is positively correlated with the initial load or the real-time load.

[0175] In some embodiments, the temperature setting unit processes the initial load or the real-time load according to the drying temperature adjustment function to obtain the second drying control temperature. The drying temperature adjustment function is a predetermined function that characterizes the positive correlation between the initial load or the real-time load and the second drying control temperature.

[0176] In some embodiments, the control unit 302 controls the drying drum of the clothing processing equipment to continue rotating according to the first rotation control parameter while continuing to control the drying operation of the load to be dried according to the second drying control temperature, and the first rotation control parameter includes a first rotation speed and a first turn-stop ratio; wherein the first rotation speed is less than the second rotation speed used when drying the load to be dried according to the first drying control temperature, and / or the first turn-stop ratio is less than the second turn-stop ratio used when drying the load to be dried according to the first drying control temperature.

[0181] In some embodiments, before drying the load to be dried according to the first drying control temperature control, the rotation setting unit determines a second rotation control parameter according to an initial load amount of the load to be dried, and the second rotation control parameter includes a second rotation speed and a second rotation-stop ratio.

[0182] In some embodiments, the rotation setting unit determines the second rotation speed based on a comparison result between the initial load and a fourth load threshold; wherein, when the initial load is less than or equal to the fourth load threshold, the target rotation speed that makes the beating path of the load to be dried the longest is used as the second rotation speed; and when the initial load is greater than the fourth load threshold, the second multi-combination cycle speed is used as the second rotation speed.

[0183] In some embodiments, when the target rotation speed is determined to be the first rotation speed, the rotation setting unit determines the target rotation speed according to the initial load; or, a preset experimental rotation speed is used as the target rotation speed.

[0184] In some embodiments, when determining to use the second multi-combination cycle speed as the first rotation speed, the rotation setting unit selects at least two combinations from a plurality of preset speeds to form a second multi-combination cycle speed, wherein the preset speeds include at least one low speed, at least one intermediate speed and at least one high speed.

[0185] In some embodiments, while the control unit 302 continues to control the drying operation of the load to be dried according to the second drying control temperature, the dryness detection unit 301 continues to detect the real-time dryness of the load to be dried; when the dryness detection unit 301 determines that the real-time dryness is greater than the second dryness, the control unit 302 controls the cooling operation of the load to be dried.
