Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and specifically provides a control method and device for a clothing processing device, and the clothing processing device. Background Art

[0002] At present, many clothes processing devices are provided with a standard drying mode. The standard drying mode is a mode in which relatively high temperature hot air is blown to wet clothes, so that the moisture in the wet clothes absorbs heat and evaporates quickly. Since the standard drying mode is a mode in which relatively high temperature hot air is used to heat the wet clothes, many users naturally think that the standard drying mode is a mode that can achieve fast drying of wet clothes, and use it as a common drying mode.

[0003] However, in drying tests and actual user applications, in some cases the time taken to dry wet clothes using the standard drying mode is longer than that taken using other drying modes (such as the low-temperature drying mode), and the frequency of clothes being damaged in the standard drying mode is greater than that in other drying modes.

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.

[0052] 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".

[0053] The disclosed embodiment provides a control method for a clothes processing device, which controls the drying temperature of a load to be dried based on the load amount to be dried, thereby achieving faster drying of the load.

[0054] 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.

[0055] The clothing processing device is a device used to dry clothes and other loads that need to be dried, thereby drying the loads that need 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.

[0056] 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, the clothes processing devices in actual applications are mostly heat pump drying devices or condensing drying devices.

[0057] 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 heating component, a drying drum and a condensation dehumidification component.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] Figure 1 is a flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure. Figure 1As shown, the control method of the clothing processing device provided by the embodiment of the present disclosure includes S110-S130.

[0063] S110: Detecting the initial load amount of the load to be dried.

[0064] In the disclosed embodiment, after the drying program is started, the clothing processing device detects the initial load of the load to be dried. The initial load is data used to characterize the weight characteristics of the load to be dried when drying begins. In a specific implementation, the initial load can be the weight of the load to be dried, or other parameters that indirectly characterize the weight of the initial load. It should be noted that the parameters that indirectly characterize the weight of the initial load should be positively correlated with the weight of the initial load.

[0065] In a specific implementation, the clothes processing device may determine the initial load amount of the load to be dried in various ways.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] As analyzed above, in the embodiment of the present disclosure, after the clothing processing device starts the drying program, the initial load amount of the load to be dried is detected. In actual applications, the clothing processing device may have multiple drying modes, such as a standard drying mode, a low-temperature drying mode, and a quick drying mode. The standard drying mode is generally a mode in which hot air at a preset higher temperature is blown to wet clothes, so that the moisture in the wet clothes absorbs heat and evaporates quickly. The low-temperature drying mode is generally a mode in which low temperature is used to dry clothes made of special materials (such as polyester fibers, silk, etc.). The quick drying mode is generally a mode in which high temperature is forced to be used to dry clothes. The aforementioned various drying modes may be configured with an operation to detect the initial load amount of the load to be dried.

[0073] Correspondingly, in a specific implementation, the aforementioned S110 detecting the initial load amount of the load to be dried specifically includes S111.

[0074] Make sure the preset drying mode is selected and check the initial load size of the load to be dried.

[0075] The preset drying mode is a drying mode in which the drying control temperature can be adjusted according to actual conditions. The preset drying mode can be the aforementioned standard drying mode, low temperature drying mode and fast drying mode.

[0076] S120: determining an initial drying control temperature according to the initial load, wherein the initial drying control temperature is positively correlated with the initial load.

[0077] After determining the initial load amount, the initial drying control temperature can be determined based on the initial load amount. The initial drying control temperature is a control temperature used to control the drying temperature of the load to be dried. More directly, the initial drying control temperature can be a control parameter used to control the heating power of the heating component. By controlling the heating power of the heating component based on the initial drying control temperature, the temperature of the hot air blown to the load to be dried can be controlled.

[0078] In the disclosed embodiment, the initial drying control temperature is positively correlated with the initial load, that is, the larger the initial load, the larger the corresponding initial drying control temperature. That is, if the initial load is small, the clothes processing device will use a smaller initial drying control temperature. If the initial load is large, the clothes processing device will use a larger initial drying control temperature.

[0079] It should be noted that the positive correlation between the aforementioned initial drying control temperature and the initial load is a positive correlation within a specific temperature range, and the value of the initial drying control temperature will not exceed the pre-set safe drying range.

[0080] It should also be noted that the initial drying control temperature is positively correlated with the initial load, which may be a linear positive correlation or a nonlinear positive correlation. The nonlinear positive correlation may be a step function positive correlation, a quadratic function positive correlation, or the like.

[0081] In some embodiments, the laundry processing device may determine the initial drying control temperature using the following steps S121-S123: The following steps S121-S123 are substantially a method for determining the initial drying control temperature using a step function positive correlation.

[0082] S121: Compare whether the initial load is greater than or equal to a first load threshold; if so, execute S122; if not, execute S123.

[0083] S122: Using the first preset temperature as the initial drying control temperature.

[0084] S123: Using the second preset temperature as the initial drying control temperature.

[0085] 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.

[0086] 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, so the first preset temperature is used as the initial 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 second preset temperature is used as the initial drying control temperature.

[0087] Here, it should be noted that the first preset temperature is lower than the second preset temperature. In a specific implementation, the first preset temperature can be set to be lower than 60°C, for example, 55°C; the second preset temperature can be set to be higher than 60°C, for example, 65°C.

[0088] The initial drying control temperature is determined by comparing the initial load and the first load threshold. In other embodiments, multiple load thresholds may be set in the clothing processing device, and adjacent load thresholds correspond to a specific preset temperature, and the preset 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 preset temperature, the corresponding preset temperature can be used as the initial drying control temperature.

[0089] In some other embodiments, the clothes treating apparatus may determine the initial drying control temperature in S124 as follows.

[0090] S124: using a drying temperature determination function to process the initial load to obtain an initial drying control temperature.

[0091] The drying temperature determination function is a predetermined function that characterizes the positive correlation between the initial load amount and the initial drying control temperature. The drying temperature determination function may be the aforementioned quadratic function, linear function, etc. It should be noted that the drying temperature determination function is a function that characterizes the positive correlation between the load amount and the initial drying control temperature. After determining the initial load amount, the initial load amount is input into the drying temperature determination function, and the corresponding initial drying control temperature can be obtained. When the drying temperature determination function is used to determine the initial drying control temperature, different initial load amounts may correspond to different initial drying control temperatures.

[0092] After the initial drying control temperature is determined, S130 may then be performed.

[0093] S130: Controlling the drying operation of the load to be dried according to the initial drying control temperature.

[0094] After the initial drying control temperature is determined, the clothes treating apparatus may then perform a drying control operation according to the initial drying control temperature.

[0095] The clothing processing device can adopt a negative feedback method to perform a drying operation on the load to be dried based on the initial drying control temperature. In a specific implementation, a temperature sensor can be set in the ventilation channel between the heating component and the drying drum, and the temperature sensor detects the hot air temperature output by the heating component and generates a real-time temperature signal. The temperature sensor then sends the temperature signal to the controller of the clothing processing device. The controller of the clothing processing device takes the initial drying control temperature as the control target. According to the difference between the real-time temperature signal and the initial drying control temperature, the controller determines the negative feedback adjustment amount for adjusting the heating power of the heating component, and uses the negative feedback adjustment amount to control the clothing processing device to perform the drying operation.

[0096] The following analyzes the effect of drying control using the control method for the clothing processing device provided by the embodiment of the present disclosure.

[0097] 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.

[0098] 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. In addition, if the load is dried before the temperature reaches the cooling point during the drying process, but the clothing processing equipment continues the drying operation, on the one hand, the drying time will be increased; on the other hand, since the load is in a high temperature environment for a long time, the load is easily damaged or deformed, affecting the user experience.

[0099] 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 initial drying control temperature according to the initial load amount, and then perform a drying operation on the load to be dried according to the initial drying control temperature. Based on the above analysis, using the solution provided by the embodiment of the present disclosure, when the initial load amount is small, compared with using a set larger initial drying control temperature, using a corresponding smaller initial drying control temperature can achieve the drying operation of the load in a shorter time, and the drying energy consumption is also reduced accordingly.

[0100] 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 another embodiment, the control method of the clothes processing device includes S210-S240.

[0101] S210: Detecting the initial load amount of the load to be dried.

[0102] S220: Determine an initial drying control temperature according to the initial load, where the initial drying control temperature is positively correlated with the initial load.

[0103] The aforementioned S210-S220 are the same as S110-S120 in the previous embodiment, and will not be repeated here. The following is an analysis of the differences between the embodiment of the present disclosure and the previous embodiment.

[0104] S230: Determine a first rotation control parameter of a drying drum in the laundry processing device according to the initial load.

[0105] In the disclosed embodiment, after the initial load is determined, not only the initial drying control temperature is determined according to the initial load, but also the first rotation control parameter of the drying drum is determined according to the initial load. The first rotation control parameter is a parameter used to control the rotation characteristics of the drying drum when the initial drying control temperature is used to dry the load to be dried. The first rotation control parameter includes a first rotation speed and a first turn-stop ratio. The first rotation speed characterizes the rotation speed of the drying drum when it is rotating. The first turn-stop ratio characterizes the ratio of the rotation time and the stop time of the drying drum. Under different first rotation speeds and first turn-stop ratios, the load to be dried has different rotation characteristics.

[0106] S240: Controlling the drying operation of the load to be dried according to the initial drying control temperature, and controlling the rotation of the drying drum according to the first rotation control parameter.

[0107] After determining the initial drying control temperature and the first rotation control parameter, the clothes processing device then controls the rotation of the drying drum according to the initial drying control temperature and the first rotation control parameter to dry the load to be dried.

[0108] Under normal circumstances, in a standard drying mode, the clothes processing device controls the rotation of the drying drum at a specific rotation rate to increase the heat exchange area between the load to be dried and the hot air, thereby accelerating the drying speed. However, the inventors of the present application have found that when the initial load of the load to be dried is different, the specific rotation rate is used to control the rotation of the drying drum, and the tumbling and rolling characteristics of the load to be dried are different, so that the contact specific surface area of ​​the hot air is different.

[0109] In order to solve the above problems, the embodiment of the present disclosure determines the first rotation control parameter according to the initial load of the load to be dried. When the drying operation is performed according to the initial drying control temperature, the rotation of the drying drum is controlled according to the first rotation control parameter to increase the specific surface area of ​​the load to be dried in contact with the hot air as much as possible, speed up the drying speed, and reduce the drying time.

[0110] In a specific implementation, the aforementioned S230 may include the following S231 - S233 .

[0111] S231: Compare whether the initial load is less than or equal to the second load threshold; if so, execute S232; if not, execute S233.

[0112] S232: The target rotation speed that makes the beating path of the load to be dried the longest is set as the first rotation speed.

[0113] S233: The multi-combination cycle rotation speed is used as the first rotation speed.

[0114] The second load threshold is a preset threshold used to determine the initial load level.

[0115] When the initial load is less than the second load threshold, the rotation speed that minimizes the drying time is the target rotation speed that makes the path of the load to be dried the longest, so the target rotation speed can be used as the first rotation speed. When the initial load is greater than the second load threshold, the drying time can be minimized by using the multi-combination cycle speed as the first rotation speed.

[0116] 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 first rotation speed can make the drying load be fully beaten and developed, increasing its contact area with the hot air.

[0117] When the initial load of the load to be dried is greater than the second 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 a multi-combination cycle rotation speed as the first rotation speed. The multi-combination cycle rotation speed is a rotation speed formed by combining at least two preset rotation speeds and executed cyclically.

[0118] In order to use the multi-combination cycle speed as the first 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.

[0119] As analyzed above, after the initial drying control temperature and the first rotation control parameter are determined, the clothes processing device can then be controlled to operate according to the initial drying control temperature and the first rotation control parameter.

[0120] In order to determine whether the load to be dried has been dried according to actual conditions, a sensor for detecting the real-time dryness of the load to be dried is also configured in the clothing processing device, as long as the sensor can sense the dryness of the load. During the process of drying clothes in the clothing processing device, the sensor monitors and senses in real time to determine the real-time dryness of the load to be dried. In a specific implementation, the aforementioned sensor can be a humidity sensor or a temperature sensor. It should be noted that when the sensor is a temperature sensor, after obtaining the temperature change data, the clothing processing device needs to convert the temperature change data into corresponding dryness data according to the set conversion relationship.

[0121] In some embodiments, while performing a drying operation on the load to be dried according to the initial drying control temperature, the clothes processing apparatus may further include the following S250-S260.

[0122] S250: Detecting the real-time dryness of the load to be dried.

[0123] S260: 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 intermediate drying control temperature.

[0124] In the embodiment of the present disclosure, when it is determined that the implemented dryness is greater than the first dryness, the clothes processing device uses the intermediate drying control temperature as the target control temperature and continues to dry the load to be dried. It should be noted that the intermediate drying control temperature is less than the initial drying control temperature.

[0125] Since the drying process mostly absorbs heat through the evaporation of water, it is ensured that the temperature of the load to be dried will not be damaged due to excessive temperature. As the drying operation proceeds, the water in the load to be dried gradually evaporates, and the possibility of a sudden and rapid increase in problems with the clothes to be dried becomes greater, that is, the probability that the clothes may be damaged will also increase. In order to avoid this problem, in the embodiment of the present disclosure, after detecting that the real-time dryness of the load to be dried is greater than the first preset dryness, the intermediate drying control temperature is used to continue to control the drying operation of the drying load, which can avoid the problem of the load to be dried heating up too quickly due to the excessively high temperature of the hot air used for drying, thereby reducing the probability of the load to be dried being damaged.

[0126] In a specific implementation, the intermediate drying control temperature can be set differently according to the initial drying control temperature setting. For example, when the initial drying control temperature is the first preset temperature, a temperature lower than the first preset temperature can be used as the intermediate drying control temperature; and when the initial drying control temperature is the second preset temperature, a temperature lower than the second preset temperature can be used as the intermediate drying control temperature.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] In some embodiments, the clothes processing device can also determine the intermediate drying control temperature according to the initial load, and the intermediate drying control temperature is a control temperature that is positively correlated with the initial load. As the initial load increases, the intermediate drying control temperature can also increase accordingly. However, it should be noted that the intermediate drying control temperature should still be lower than the initial drying control temperature.

[0131] In some embodiments, when the laundry processing device performs a drying operation, especially when driving the load to be dried to rotate, it can also detect the real-time load amount of the load to be dried. Accordingly, when the laundry processing device determines that the real-time dryness is greater than the first dryness, it can determine the intermediate drying control temperature according to the implemented load amount.

[0132] In some embodiments of the present disclosure, while executing the aforementioned S260, the laundry processing apparatus may further execute the following S270.

[0133] S270: Determine that the real-time dryness is greater than the first dryness, and control the drying drum of the clothes processing device to rotate according to the second rotation control parameter.

[0134] The second rotation control parameter is a parameter used to control the rotation characteristics of the drying drum when the intermediate drying control temperature is used to continue the drying operation on the load to be dried. The second rotation control parameter includes a second rotation speed and a second rotation-stop ratio. In the disclosed embodiment, the second rotation speed is less than the aforementioned first rotation speed, and the second rotation-stop ratio is less than the aforementioned first rotation-stop ratio.

[0135] In actual applications, as the drying progresses, the moisture content in the load to be dried decreases and the load is gradually dried. At this time, if a larger rotation control parameter is continued to be used to control the rotation of the drying drum, the load to be dried may be wrinkled due to severe beating during the subsequent drying process. In order to avoid this problem, in the embodiment of the present disclosure, after the dryness is greater than the first dryness, the clothing processing device uses a smaller second rotation speed and a second rotation-stop ratio to control the load to be dried to rotate slowly in the drying drum, thereby reducing the possibility of wrinkles in the load to be dried.

[0136] In a specific implementation, if the first rotation speed in the first rotation control parameter is the target rotation speed that makes the drying load fall path the longest, the second rotation speed can be set to be smaller than the first rotation speed, for example, it can be 35-45 rpm. If the first rotation speed is a cyclic rotation speed, the second rotation speed can be set to a smaller cyclic rotation speed, for example, only the rotation speed combination of 40 and 50 rpm is used as the cyclic rotation speed.

[0137] If the aforementioned second rotation speed is lower than the first rotation speed, the second rotation-stop ratio is also lower than the aforementioned first rotation-stop ratio.

[0138] While executing the aforementioned S260-S270, the clothes processing device may 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 preset dryness, it is determined that the load to be dried is substantially dry, and then a cooling operation may be performed on the load to be dried, so that the load to be dried and the clothes processing device are cooled down, thereby preventing the user from being scalded when removing the dried load. It should be noted that the aforementioned second preset dryness is greater than the first dryness.

[0139] 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 second rotation control parameter, or control the drying drum to continue rotating at a second rotation speed slower than the second drying control parameter to speed up the cooling of the load.

[0140] 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.

[0153] In some embodiments, while the drying operation of the load to be dried is continuously controlled according to the intermediate drying control temperature, the dryness detection unit continues to detect the real-time dryness of the load to be dried.
