Referring to fig. 1 to 2, the present invention mainly provides a clothes drying prompting method and a clothes processing apparatus, and the prompting method is applied to the clothes processing apparatus. The laundry treating apparatus may take many forms, such as a dryer. Taking a drum dryer as an example, the clothes processing equipment comprises a drum 100, wherein cotton wool fabrics to be dried wait for drying objects to be in the drum 100, and when the drum 100 rotates, the objects to be dried move along with the drum and are in contact with flowing high-temperature air, and the high-temperature air takes away moisture on the objects to be dried (the moisture is taken away by evaporation), so that the objects to be dried are dried quickly. The laundry treating apparatus includes a drum 100 and a tub 200, and the drum 100 is disposed inside the tub 200 to rotate compared to the tub 200. A heating device is provided at the intake port 310 of the drum 100 to adjust the temperature of air introduced into the drum 100. The laundry treating apparatus further includes a gas driving device 500, and the gas driving device 500 is disposed in a wind tunnel of the laundry treating apparatus to draw gas inside the drum 100 such that heated air can enter the drum 100 from the wind inlet 310 and can be discharged out of the drum 100 from the wind outlet 320 of the drum 100. The gas-driven apparatus 500 may be in many forms such as a suction pump, a vacuum pump, etc. Of course, in some embodiments, in order to avoid discharging a large amount of hot and humid air directly into the room, the condenser 600 and the condensing fan 700 are disposed at the position of the air outlet, the hot and humid air passes through the condenser 600, and the condensing fan 700 cools the condenser 600, so that the hot and humid air is cooled down in temperature and humidity while passing through the condenser 600.

The following will mainly describe the specific steps of the clothes drying prompting method.

Referring to fig. 1 to 3, in an embodiment of the present invention, the laundry treating apparatus 300 includes a drum 100 and a heat exchanging device in communication with the drum 100, and the laundry drying control method includes the steps of:

s100: acquiring a coating instruction; acquiring the current dryness of the clothes dried in the current drum 100 according to the clothes adding instruction;

s200: comparing the current dryness with a preset dryness;

s300: determining that the current dryness is greater than or equal to a preset dryness;

s400: determining the coating success;

s500: determining that at least two kinds of clothes to be dried with different drying difficulty degrees exist in the drum 100;

s600: determining that clothes which are easy to dry in the dried clothes reach a preset drying degree;

s700: closing the heat exchange device and sending prompt information to a specified object;

s800: and after the preset time, the heat exchange device is started to continuously dry clothes which are difficult to dry in the dried clothes.

Specifically, in this embodiment, there are various manners of obtaining the clothes adding instruction, and the clothes adding instruction may be an instruction sent by an external terminal, such as a mobile terminal (a mobile phone, a remote controller, a tablet computer), a fixed terminal (a server, a cloud), an operation or instruction input of the user on the clothes processing device 300, and the like. It may also be the result of the clothes treating apparatus 300 performing detection and judgment according to the current situation (for example, detecting the approach of the clothes held by the user by the camera or the sensing device, preparing to add the clothes to the drum 100 of the dryer). The content of the clothes adding instruction may be only a control instruction for starting a clothes adding program, and in some embodiments, the clothes adding instruction may also be related information carrying clothes to be added, such as material information, clothes type information, and the like.

The laundry condition in the drum 100 is obtained according to the laundry adding instruction, including the type and material information of the laundry, and the current dryness of the dried laundry. There are many ways to obtain the current dryness, such as by obtaining a temperature difference or a humidity difference between the air inlet 310 and the air outlet 320, and of course, in some embodiments, the humidity value in the drum 100 may also be obtained directly. After the current dryness is obtained, the current dryness is compared with the preset dryness to judge which stage of the drying process the current clothes drying process is in. If the current dryness is smaller than the preset dryness, the current dryness is in the early stage of the drying process, the humidity of the clothes in the drum 100 is high, the influence on the humidity in the drum 100 is not too large after the clothes are added, and the drying is continued according to the original drying strategy after the clothes are successfully added. Wherein, the mode of confirming the clothes adding success has a plurality of modes, such as image identification, etc.; of course, the original clothes drying strategy does not mean that the clothes drying time and the clothes drying power are not changed at all, but the clothes drying time and/or the clothes drying power can be properly adjusted according to the added amount of the clothes.

If the current dryness is greater than or equal to the preset dryness, it indicates that the drying process is in the later stage, and the humidity of the clothes in the drum 100 is low, and after the clothes are added, the influence on the humidity in the drum 100 is high, and meanwhile, the difference between the drying time of the clothes in the drum 100 is also high. At this time, a "dry first take" strategy needs to be implemented to ensure that the previously dried laundry can be taken out first, thereby reducing the possibility of damage. Specifically, after the dryness is determined to be high, the coating state is acquired first, and whether the current coating action is finished or not is judged. If the current clothes adding operation is completed, it is necessary to determine that there are at least two kinds of clothes to be dried in the drum 100, which are different in difficulty level. Among them, there are many factors that affect how hard the laundry is dried, such as the type of the laundry, the fabric of the laundry, and the like. When the types of the clothes are different, the corresponding shapes and sizes of the clothes are obtained according to the types of the clothes, and therefore the volume of the clothes is obtained. Bulky laundry is considered to be harder to dry and small laundry is considered to be easier to dry. When the two kinds of difficulty levels of drying reach a certain value, it is considered that at least two kinds of difficulty levels of drying are different.

After determining that the two kinds of clothes to be dried are different in difficulty, the heat exchanging apparatus is turned on to dry the clothes in the drum 100. It is worth mentioning that in some embodiments, the heat exchange device can be closed in the clothes adding process, so that energy can be saved, and potential safety hazards of hurting users can be reduced; in other embodiments, the heat exchanging device may be opened during the process of coating, so as to avoid excessive temperature drop in the drum 100, facilitate quick drying after coating, and improve the overall drying efficiency.

The heat exchange device may include a heating device, and may also include a heating device and a gas driving device (such as a fan). That is, the heat exchange device may include not only the heating device, but also a gas driving device for improving the heat exchange effect in some embodiments.

In order to better distinguish the heating power of the heat exchange device during the drying process, the heating power of the heat exchange device during the time period from the time when the laundry is added to the time when the relatively easily dried laundry is taken out can be defined as the first heating power. And defining the heating power of the heat exchange device as a second heating power in the time period from the time when the clothes which are easy to dry are taken out to the time when the drying is finished.

The first heating power may be a preset heating power, or may be a heating power selected according to information such as a type, fabric, and quantity of the current laundry (a mapping table of a laundry type, a laundry fabric, a laundry weight, and a heating power may be stored in the storage device of the laundry processing apparatus 300). After drying is performed for a certain period of time, drying degree detection is performed on the laundry in which drying is easily performed. When the clothes which are easier to dry in the dried clothes are determined to reach the preset drying degree, the clothes are dried and can be taken out. At this time, the heat exchanging apparatus is turned off and a prompt message is sent to the designated object to cool the laundry in the drum 100, so that the user can take out the dried laundry conveniently. The designated object can be terminal equipment, such as a fixed terminal and a mobile terminal (a mobile phone, a remote controller, a tablet computer, a smart watch and the like); or a prompting device (light, sound, vibration and the like), such as a signal lamp, a horn, a grower and the like; and may also be designated areas such as guests, restaurants, bathrooms, bedrooms, living balconies, and the like. The prompt message is sent to prompt the user that the dried laundry is available in the drum 100. After the clothes to be dried are taken out, the drying process of the clothes with high drying difficulty (clothes not to be dried) needs to be continued. That is, after the preset time period, the heat exchange device is turned on to continuously dry the clothes which are difficult to dry in the dried clothes. Thus realizing the 'first dry first fetch'.

In this embodiment, a clothes adding instruction is first obtained, and the current dryness of the clothes to be dried in the drum 100 is obtained according to the clothes adding instruction; and comparing the current dryness with a preset dryness; determining a current drying process after determining that the current dryness is greater than or equal to the preset dryness; judging the clothes adding action, and determining that at least two kinds of clothes to be dried with different drying difficulty degrees exist in the roller 100 after the clothes adding is determined to be successful; after confirming that the clothes with different drying degrees exist, starting the heat exchange device to dry the clothes in the drum 100; after drying for a certain time, detecting the drying degree of the clothes in the drum 100, and determining that the clothes which are easier to dry in the dried clothes reach the preset drying degree, which indicates that the clothes which are easier to dry are already dried and can be taken out; at this time, the heat exchange device is closed and prompt information is sent to the designated object, and the heat exchange device is closed, so that the clothes in the drum 100 can be cooled, the clothes can be taken out safely by a user, and the damage degree of the dried clothes in the subsequent drying process can be greatly reduced even if the clothes are not taken out by the user and the clothes are cooled under some working conditions; after the preset time, the heat exchange device is opened to continuously dry clothes which are difficult to dry in the dried clothes, so that the clothes can be dried firstly and firstly in the drying process, a user can timely take the clothes which are easy to dry out from the roller 100, the drying for too long time is avoided, the service life of the clothes is prolonged, and meanwhile, the clothes which are difficult to dry are dried in a higher efficiency (after the clothes which are easy to dry out are taken out, the drying efficiency of the clothes which are difficult to dry out can be improved); thus, even if the user adds clothes to the clothes treatment device 300 at the end of the drying process, the clothes treatment device 300 can receive and dry according to a preset strategy of "dry first and get first", so that the clothes to be dried can be put into the clothes treatment device 300 at any time, and the convenience of drying the clothes by the user is greatly improved.

There are various ways to obtain the current dryness of the clothes dried in the drum 100, and two examples are described below.

Referring to fig. 4, in some embodiments, the step of obtaining the current dryness of the laundry dried in the current drum 100 according to the clothes adding instruction includes:

s110: acquiring a first inlet air temperature of an inlet 310 and a first outlet air temperature of an outlet 320 of the roller 100;

s120: acquiring a first current temperature difference value between a first air inlet temperature and a first air outlet temperature;

s130: and determining the current dryness of the dried clothes according to the first current temperature difference value.

Specifically, in this embodiment, first, the temperature sensor disposed at the air inlet 310 is used to obtain a first inlet air temperature, and the temperature sensor disposed at the air outlet 320 is used to obtain a first outlet air temperature. And calculating a first current temperature difference value between the first inlet air temperature and the first outlet air temperature. Since the air is heated and then enters the drum 100 to exchange heat with the clothes, the temperature of the air after heat exchange is lower than that of the air inlet. The first current temperature difference value may be obtained by calculating a difference between the first inlet air temperature and the first outlet air temperature. And after the first current temperature difference value is obtained, judging the dryness of the current clothes according to the first current temperature difference value. When the first current temperature difference is smaller, it indicates that the temperature of the laundry in the drum 100 is higher, it indicates that the heat lost by the heat exchange of the air in the drum 100 is smaller, and it indicates that the drying degree of the laundry in the drum 100 is higher. When the first current temperature difference is larger, it indicates that the heat lost by the heat exchange of the air in the drum 100 is larger, it indicates that the temperature of the laundry in the drum 100 is lower, and it indicates that the drying degree of the laundry in the drum 100 is lower. Of course, in some embodiments, a mapping table of "first current temperature difference value-current dryness" may be stored in the storage device, and the current dryness corresponding to the first current temperature difference value may be queried according to the mapping table.

Referring to fig. 5, in some embodiments, the step of obtaining the current dryness of the laundry dried in the current drum 100 according to the clothes adding instruction includes:

s140: acquiring a first inlet air humidity of an inlet 310 and a first outlet air humidity of an outlet 320 of the roller 100;

s150: acquiring a first current humidity difference value between the first inlet air humidity and the first outlet air humidity;

s160: and determining the current dryness of the dried clothes according to the first current humidity difference value.

Specifically, in this embodiment, first the humidity sensor disposed at the air inlet 310 obtains a first inlet air humidity, and the humidity sensor disposed at the air outlet 320 obtains a first outlet air humidity. And calculating a first current humidity difference value between the first inlet air humidity and the first outlet air humidity. Since the air is heated and enters the drum 100 to exchange heat with the clothes, the humidity of the air after heat exchange is higher than that of the air at the air inlet. The first current humidity difference value may be obtained by calculating a difference between the first outlet humidity and the first inlet humidity. And after the first current humidity difference value is obtained, judging the dryness of the current clothes according to the first current humidity difference value. When the first current humidity difference is smaller, it indicates that the humidity of the laundry in the drum 100 is lower, it indicates that the moisture carried by the air after heat exchange in the drum 100 is less, and it indicates that the drying degree of the laundry in the drum 100 is higher. When the first current humidity difference is larger, it indicates that the moisture carried by the air after heat exchange in the drum 100 is more, indicates that the humidity of the laundry in the drum 100 is higher, and indicates that the drying degree of the laundry in the drum 100 is lower. Of course, in some embodiments, a mapping table of "first current humidity difference value to current dryness" may be stored in the storage device, and the current dryness corresponding to the first current humidity difference value may be queried according to the mapping table.

It is worth noting that in some embodiments, the first current humidity difference value and the first current temperature difference value may be considered simultaneously, wherein the influence weight of the first current humidity difference value is greater than 0.6, and the influence weight of the first current temperature difference value is lower than 0.4. Of course, the corresponding mapping table "first current humidity difference value-first current temperature difference value-current dryness" may be stored, and after the first current humidity difference value and the first current temperature difference value are obtained, the corresponding current dryness may be obtained from the table.

In some embodiments, after the laundry is added, the workload of the laundry treating apparatus 300 is necessarily increased, and when the increased workload reaches a preset amount, the drying efficiency may be improved by increasing the heat exchange device power of the dryer to reduce the operating time. When the increased workload is small, the drying strategy of the dryer may not be adjusted. The following description will be given by taking several specific examples.

Referring to fig. 6, in order to improve the overall drying efficiency of the dryer. After the step of determining the success of the coating, the method further comprises the following steps:

s910: acquiring a second inlet air temperature of the air inlet 310 and a second outlet air temperature of the air outlet 320 of the roller 100;

s920: calculating a second current temperature difference value between the second inlet air temperature and the second outlet air temperature;

s930: and determining that the second current temperature difference value is greater than or equal to the preset temperature difference, and increasing the power of the heat exchange device.

Specifically, in this embodiment, after the clothes are added, the temperature sensor disposed at the air inlet 310 obtains the second inlet air temperature, and the temperature sensor disposed at the air outlet 320 obtains the second outlet air temperature. And calculating a second current temperature difference value between the second inlet air temperature and the second outlet air temperature. The second current temperature difference will be greater than the first current temperature difference due to the addition of the laundry to be dried.

Since the air is heated and then enters the drum 100 to exchange heat with the clothes, the temperature of the air after heat exchange is lower than that of the air inlet. The second current temperature difference value may be obtained by calculating a difference between the second inlet air temperature and the second outlet air temperature. And comparing the second current temperature difference value with the preset temperature difference, and when the second current temperature difference value is smaller than the preset temperature difference, indicating that the current temperature change is smaller, the influence of the added clothes on the drying process is smaller, and at the moment, the current drying strategy can not be adjusted. When the second current temperature difference value is greater than or equal to the preset temperature difference value, it is indicated that the current temperature change is large, and the influence of the added clothes on the drying process is large, and at this time, the drying efficiency can be improved by improving the power of the heat exchange device.

As to how to increase the power of the heat exchanging device, there are many ways, for example, it can be adjusted by obtaining the difference between the second current temperature difference value and the first current temperature difference value, and the larger the difference is, the larger the influence of the added laundry on the drying process is, the more the drying power needs to be increased; the smaller the difference, the smaller the influence of the added laundry on the drying process, and no adjustment of the drying strategy is required. The power of the heat exchanging means may also be adjusted by calculating the difference between the second current temperature difference and the preset temperature difference. The following description will be given by taking an example.

Referring to fig. 7, the step of determining that the second current temperature difference value is greater than or equal to the preset temperature difference, and increasing the power of the heat exchange device includes:

s931: comparing the second current temperature difference value with a preset temperature difference value to obtain a temperature difference value;

s932: the difference in temperature is greater than or equal to zero;

s933: and increasing the power of the heat exchange device according to the temperature difference value, wherein the temperature difference value is positively correlated with the power increasing amplitude.

Specifically, after it is determined that the second current temperature difference value is greater than or equal to the preset temperature difference, a phase difference degree-temperature difference value of the second current temperature difference value and the preset temperature difference is calculated. At this time, the temperature difference is greater than or equal to zero, which indicates that the drying strategy needs to be adjusted by increasing the power of the heat exchange device. The larger the difference in temperature, the higher the amplitude of the power required to increase the heat exchange device, and the smaller the difference in temperature, the smaller the amplitude of the power required to increase the heat exchange device. Of course, a mapping table of "temperature difference value-amplitude of power of the heat exchange device to be increased" may be prestored in the storage device, so that the amplitude of power to be adjusted may be quickly obtained according to the calculated temperature difference value. Therefore, the power of the heat exchange device can be adjusted according to the specific condition of adding clothes, and the drying efficiency after the clothes are added is improved.

Referring to fig. 8, in order to improve the overall drying efficiency of the clothes dryer, after the step of determining the success of the clothes adding, the method further includes:

s940: acquiring second inlet air humidity of the air inlet 310 and second outlet air humidity of the air outlet 320 of the roller 100;

s950: calculating a second current humidity difference value between the second inlet air humidity and the second outlet air humidity;

s960: and determining that the second current humidity difference value is greater than or equal to the preset humidity difference, and increasing the power of the heat exchange device.

Specifically, in this embodiment, after the clothes are added, the humidity sensor disposed at the air inlet 310 obtains the second inlet air humidity, and the humidity sensor disposed at the air outlet 320 obtains the second outlet air humidity. And calculating a second current humidity difference value between the second inlet air humidity and the second outlet air humidity. The second current humidity difference value will be greater than the first current humidity difference value due to the addition of the laundry to be dried.

Because the air enters the drum 100 after being heated to exchange heat with the clothes, the humidity of the air after heat exchange is higher than that of the air inlet. The second current humidity difference value may be obtained by calculating a difference between the second outlet humidity and the second inlet humidity. And comparing the second current humidity difference value with the preset humidity difference value, and when the second current humidity difference value is smaller than the preset humidity difference value, indicating that the current humidity change is smaller, the influence of the added clothes on the drying process is smaller, and at the moment, the current drying strategy can not be adjusted. When the second current humidity difference value is greater than or equal to the preset humidity difference value, it is indicated that the current humidity changes greatly, and the influence of the added clothes on the drying process is large, and at this time, the drying efficiency can be improved by improving the power of the heat exchange device.

As to how to increase the power of the heat exchanging device, there are many ways, for example, it can be adjusted by obtaining the difference between the second current temperature difference value and the first current temperature difference value, and the larger the difference is, the larger the influence of the added laundry on the drying process is, the more the drying power needs to be increased; the smaller the difference, the smaller the influence of the added laundry on the drying process, and no adjustment of the drying strategy is required. The power of the heat exchange device may also be adjusted by calculating the difference between the second current humidity difference and the preset humidity difference. The following description will be given by taking an example.

Referring to fig. 9, the step of determining that the second current humidity difference value is greater than or equal to the preset humidity difference value, and increasing the power of the heat exchange device includes:

s961: comparing the current humidity difference value with a preset humidity difference value to obtain a humidity difference value;

s962: the humidity difference is greater than or equal to zero;

s963: and increasing the power of the heat exchange device according to the size of the humidity difference, wherein the humidity difference is positively correlated with the power increase amplitude.

Specifically, after determining that the second current humidity difference value is greater than or equal to the preset humidity difference, a phase difference degree-humidity difference value of the second current humidity difference value and the preset humidity difference is calculated. At this time, the difference value of the humidity difference is greater than or equal to zero, which indicates that the power of the heat exchange device needs to be increased to adjust the drying strategy. The larger the difference in humidity, the higher the magnitude of the power required to increase the heat exchange device, and the smaller the difference in humidity, the smaller the magnitude of the power required to increase the heat exchange device. Of course, a mapping table of "humidity difference value-amplitude of power of the heat exchange device to be increased" may be pre-stored in the storage device, so that the power amplitude to be adjusted may be quickly obtained according to the calculated humidity difference value. Therefore, the power of the heat exchange device can be adjusted according to the specific condition of adding clothes, and the drying efficiency after the clothes are added is improved.

It is worth mentioning that, before acquiring the clothes adding instruction, the clothes processing device may acquire the clothes drying instruction and dry the clothes in the drum according to the clothes drying instruction. There are many ways to determine that at least two kinds of clothes to be dried with different drying difficulty degrees exist in the drum 100, for example, the obtained drying instruction contains information affecting the drying difficulty degree of the clothes, the information may be information input and selected by a user, or information implanted by an external terminal when sending the instruction; of course, in other embodiments, the information affecting the ease with which the clothes can be dried can be detected and obtained by the clothes treating apparatus itself. The following description will be given by taking several specific examples.

In the case that the drying instruction includes information of a type of laundry, the step of determining that there are at least two kinds of laundry to be dried in the drum 100 with different degrees of difficulty of being dried according to the drying instruction includes:

extracting clothes type information of clothes to be dried from the clothes drying instruction;

acquiring the volume of each clothes to be dried according to the clothes type information;

and determining the difficulty degree of drying each clothes to be dried according to the volume of the clothes to be dried.

Specifically, in the present embodiment, the laundry type information is first extracted from the laundry drying instruction. The types of clothing may be T-shirts, inch shirts, shorts, coats, pants, quilts, sheets, and the like, among others. After the type of garment is obtained, the volume of the garment is determined according to the type of garment, for example, the outer cover is generally larger than the T-shirts and jerseys, the trousers are generally larger than the shorts, and the bed sheets and quilt covers are generally larger than the clothes. Of course, a mapping table between the clothes types and the volume sizes may be stored in the storage device, and the corresponding volume sizes may be obtained through the clothes types in the table. And determining the difficulty level of drying the clothes to be dried according to the volume of the clothes to be dried, for example, the difficulty level of drying the clothes with large volume can be considered to be larger than the difficulty level of drying the clothes with small volume. Of course, the relationship between the volume and the drying difficulty can be judged according to other modes.

For example, the step of determining the difficulty level of drying each laundry to be dried according to the volume of the laundry to be dried includes:

acquiring a volume difference value between clothes to be dried;

comparing each volume difference value with a preset volume difference;

and determining that the volume difference value is greater than or equal to the preset volume difference, and the corresponding clothes to be dried are different in drying difficulty degree.

Specifically, in the present embodiment, after the volume size of each laundry is obtained, the volume difference between the laundry to be dried is calculated. When comparing whether any two clothes to be dried need to be judged to be different in difficulty degree, the obtained volume difference value can be compared with the preset volume difference. When the volume difference value is determined to be larger than or equal to the preset volume difference, the difference between the volumes of two pieces of clothes generating the current volume difference value is larger, the difficulty difference between the two pieces of clothes to be dried is larger, and the two corresponding pieces of clothes belong to different drying difficulties. When all the volume difference values are determined to be smaller than the preset volume difference, it is indicated that the volume difference between all the clothes is not large, the difficulty of drying the clothes to be dried is considered to be not large, and the clothes at the moment belong to the same drying difficulty.

The step of determining that at least two clothes to be dried with different drying difficulty degrees exist in the drum 100 according to the clothes drying instruction includes:

extracting the fabric information of the clothes to be dried from the clothes drying instruction;

acquiring the water absorption capacity of each piece of clothes to be dried according to the fabric information of the clothes;

and determining the difficulty level of drying each clothes to be dried according to the water absorption capacity of each clothes to be dried.

Specifically, in this embodiment, the clothes fabric information is first extracted from the clothes drying instruction. The fabric of the clothes can be pure cotton, pure hair (wool, rabbit hair, camel hair and the like), pure silk (mulberry silk, tussah silk, rayon and the like), pure hemp, cotton type chemical fiber blended yarn, synthetic fiber filament, wool type chemical fiber, pure chemical fiber fabric and the like.

After obtaining the fabric of the garment, the water absorption capacity of the garment is determined according to the fabric of the garment, for example, the water absorption capacity (water absorption capacity, hydrophilic capacity, usually measured by the weight of water absorbed by a unit volume of material) of pure cotton is usually stronger than that of pure hemp. Of course, a mapping table between the fabric of the clothes and the water absorption capacity may be stored in the storage device, and the corresponding water absorption capacity may be obtained through the fabric of the clothes in the table. And determining the difficulty degree of drying each clothes to be dried according to the water absorption capacity of the clothes to be dried, wherein for example, the difficulty degree of drying the clothes with high water absorption capacity is considered to be greater than the difficulty degree of drying the clothes with low water absorption capacity. Of course, the relationship between the water absorption capacity and the drying difficulty can be judged according to other modes.

For example, the step of determining the drying difficulty of each item of laundry to be dried according to the water absorption capacity of each item of laundry to be dried includes:

comparing the water absorption capacity difference value with a preset water absorption capacity difference value;

Specifically, in the present embodiment, after the water absorption capacity of each piece of laundry is obtained, the water absorption capacity difference between the pieces of laundry to be dried is calculated. When comparing whether any two clothes to be dried need to be judged to be different in difficulty degree, the obtained water absorption capacity difference value can be compared with the preset water absorption capacity difference. When the water absorption capacity difference is determined to be larger than or equal to the preset water absorption capacity difference, the difference between the water absorption capacities of two pieces of clothes generating the current water absorption capacity difference is larger, the difficulty of drying the two pieces of clothes is larger, and the two corresponding pieces of clothes belong to different drying difficulties. When all the water absorption capacity difference values are determined to be smaller than the preset water absorption capacity difference, the water absorption capacity difference between all the clothes is small, the clothes to be dried are considered to be difficult to dry, and the clothes at the moment belong to the same drying difficulty.

As for other steps, acquiring the volume of each clothes to be dried according to the type of the clothes; acquiring a volume difference value between clothes to be dried; and determining that the volume difference value is larger than the preset volume difference, and the drying difficulty degrees of the corresponding clothes to be dried are different. The implementation manner is the same as that in the above embodiment, and is not described herein again.

Referring to fig. 11, the step of determining that at least two clothes to be dried with different degrees of difficulty are present in the drum 100 according to the drying instruction includes:

s550: acquiring the fabric of clothes to be dried according to the clothes drying instruction;

s560: acquiring the water absorption capacity of each piece of clothes to be dried according to the fabric of the clothes;

s570: acquiring a water absorption capacity difference value between clothes to be dried;

s580: and determining that the difference value of the water absorption capacities is larger than or equal to the preset water absorption capacity difference, and the corresponding clothes to be dried are different in drying difficulty degree.

Specifically, in this embodiment, compared with the above embodiment, the information of the fabric of the clothes in this embodiment is not directly extracted from the clothes drying instruction, but the clothes processing apparatus itself acquires the information according to the clothes drying instruction. There are many ways and ways to obtain the information, for example, the information may be obtained from other associated household appliances (such as washing machine, terminal device, etc.), or the information may be obtained from the laundry processing device through a camera, etc. In particular, reference may be made to the following embodiments, which are implemented by the image capturing apparatus 800.

Similarly, the dried object in the image is analyzed, the analysis result is compared with the characteristics of the corresponding clothes fabric, and if the similarity between the clothes fabric of the dried object and the prestored clothes fabric is determined to reach the preset value (taking 90% -95% as an example), the clothes fabric of the dried object is the prestored clothes fabric.

It should be noted that, on the basis of the above embodiment, whether the clothes drying instruction contains information affecting the clothes drying difficulty or the clothes processing device obtains the information affecting the clothes drying difficulty, the clothes type and the clothes fabric can be considered at the same time. When the size of the clothes is determined to be large according to the type of the clothes and the water absorption capacity of the clothes is determined to be strong according to the fabric of the clothes, the current clothes are high in drying difficulty; when the volume of the clothes is determined to be small according to the type of the clothes, and the water absorption capacity of the clothes is determined to be weak according to the fabric of the clothes, the current difficulty in drying the clothes is low.

There are many ways to determine the clothes that are easier to dry among the dried clothes to reach the preset drying degree, and two specific examples are described below.

And comparing the air inlet temperature with the air outlet temperature, and when the air outlet temperature is 80-90% of the air inlet temperature, indicating that the integral drying degree of the current clothes is 80-90%, and at the moment, considering that the clothes which are easy to dry are already dried and can be taken out. If the outlet air temperature is higher than 90% of the inlet air temperature, it is indicated that the overall drying degree of the current clothes is higher than 90%, and the clothes which are easy to dry can be determined to be dried. If the air outlet temperature is lower than 80% of the air outlet temperature, the integral drying degree of the current clothes is lower than 80%, the clothes which are easy to dry can be determined to be not dried yet, and the drying process needs to be continued.
