Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing equipment, and in particular, relates to a drying control method for clothing processing equipment and the clothing processing equipment. Background Art

[0002] When executing the drying process, clothes processing equipment such as dryers and drum washing and drying machines usually divide the clothes into grades according to their weight, set corresponding drying parameters and time for each grade, and then consider the drying to be completed based on the longest drying time and the temperature change of the dryer fan outlet during the entire drying process. Ideally, the clothes should be dried to a moderate degree at the end of drying. However, in reality, due to differences in clothing materials and other reasons, errors may occur in judgment, and the following situations often occur: (1) Clothes are over-dried, which damages the clothes and consumes a lot of energy; (2) Clothes are not dried and the drying effect is poor. In order to ensure the drying effect, the threshold for judging the temperature change of the dryer fan outlet is often set high in the design to meet the drying effect of most clothes, resulting in over-drying of the clothes, increased energy consumption, and even damage to the clothes. Summary of the invention

[0003] In view of the above-mentioned technical problems existing in the existing clothing processing equipment, the present invention proposes a drying control method for clothing processing equipment and clothing processing equipment. After the drying function is started, timed drying is performed according to the set time, and then dehydration is performed once. During dehydration, the clothes are weighed and divided into grades. Different drying times are set according to the maximum speed reached by dehydration and the weighing grades, so as to ensure the drying effect while not wasting energy.

[0004] The present invention is implemented by the following technical solutions: A drying control method for a clothes processing device is proposed, which is applied to the clothes processing device equipped with a drying program, comprising: S1, start the drying process and execute the set time; S2, executing a dehydration process and weighing the clothes after the dehydration process is completed; S3, determining the weight class of the clothes according to the weight of the clothes; S4, determining the secondary drying time according to the weight grade; S5, executing the drying process again with the secondary drying time.

[0005] Compared with the prior art, the advantages and positive effects of the present invention are as follows: the drying control method for a clothing processing device proposed by the present invention, when the clothing processing device starts the drying function, first performs the first drying according to the set time, reduces the moisture content of the clothing through the first drying, and at the same time can reduce the eccentricity of the clothing due to different materials, thereby achieving the effect of loosening and balancing the clothing, which is beneficial to the balanced distribution of the clothing during the subsequent dehydration, and avoids the occurrence of eccentricity; performs a dehydration after the drying for the set time, further reduces the moisture content of the clothing, and can improve the energy efficiency of the subsequent second drying, and because the drying for the set time has been performed once in the early stage, the uneven distribution caused by the difference in the water absorption of the clothing is reduced, thereby being able to improve The maximum speed of high dehydration, in this case, can be performed at the highest speed after dehydration is performed again, so that more water can be thrown out of the clothes with higher moisture content after the first drying, and the situation that some clothes with low moisture content have been dried and some clothes with high moisture content have not been dried after the drying is completed is reduced, so that the moisture content of all clothes tends to be balanced; then the dehydrated clothes can be weighed more accurately, and the second drying time can be set according to the accurate weighing classification, which can reduce the occurrence rate of over-drying or under-drying, thereby improving the drying effect; through the drying control proposed by the present invention, the maximum speed that can be achieved by dehydration can be increased, thereby reducing the moisture content of the clothes to be dried, thereby reducing the time required for drying, and improving the energy efficiency of drying.

[0006] In some embodiments of the present invention, before step S1, the method further includes: After the dehydration process of the washing program is completed, weighing is performed and the set time is determined based on the weighing.

[0007] In this embodiment, a weighing is performed after the dehydration process of the previous washing program is completed, and the set time is determined according to the weighing result. The heavier the clothes, the longer the set time, and the lighter the clothes, the shorter the set time. The purpose is to allow the clothes to be initially dried through the set drying time and achieve the effect of loose and balanced distribution. Especially when the clothes are heavy, after washing and dehydration, there is a certain difference in the moisture content of the clothes in different positions. This is because under the action of centrifugal force, the closer the clothes are to the drum wall, the greater the centrifugal force is, and the more water is thrown out. On the contrary, the closer the clothes are to the center of the drum, the less water is thrown out due to the small centrifugal force. This embodiment determines the set time for the first drying by weighing, so as to loosen the clothes after the first drying, and change the distribution state of the clothes during the drying rotation to make the clothes more evenly distributed, which helps to reach the highest speed in the subsequent dehydration process, so that more water can be thrown out of the clothes with higher moisture content through dehydration, and helps to perform more accurate weighing. A more accurate second drying time is determined by more accurate weighing, so as to avoid the situation where some clothes with low moisture content in the drum have been dried after the drying is completed, while some clothes with high moisture content have not been dried.

[0008] In some embodiments of the present invention, before step S1, the method further includes: After the dehydration process of the washing program is completed, the maximum dehydration speed is obtained, and the set time is determined according to the maximum dehydration speed.

[0009] In this embodiment, after the dehydration process of the previous washing program is completed, the highest speed reached during the dehydration period is obtained, and the set time is determined according to the highest speed that can be reached for dehydration. The higher the maximum speed, the shorter the set time, and the lower the maximum speed, the longer the set time. The purpose is to allow the clothes to be initially dried and at the same time achieve a loose and balanced distribution effect through drying for a set time. Especially when the clothes are heavier, the more serious the uneven distribution of the clothes during washing and dehydration, the greater the risk of eccentricity, and the lower the possibility of reaching the maximum speed during dehydration. In this case, the moisture content of the clothes after dehydration is higher, resulting in more energy consumption and time during drying. This embodiment determines the set time for the first drying by obtaining the maximum speed reached during dehydration after washing and dehydration, so as to loosen the clothes after the first drying, change the distribution state of the clothes during the drying rotation, and make the clothes more evenly distributed, thereby helping to reach the maximum speed in the subsequent dehydration process, so that more water can be thrown out of the clothes through dehydration, which helps to perform more accurate weighing after dehydration. A more accurate second drying time can be determined through more accurate weighing, so as to avoid the situation where some clothes with low moisture content in the drum have been dried after the drying is completed, while some clothes with high moisture content have not been dried.

[0010] In some embodiments of the present invention, step S4 further includes: Determine the dry threshold according to the weight class; After step S5, the method further includes: judging whether to end the secondary drying based on a drying threshold when the secondary drying time is reached, implementing drying cooling when the drying threshold is met, and determining to extend the drying time based on the difference with the drying threshold when the drying threshold is not met, and continuing the drying program with the extended drying time.

[0011] In this embodiment, while determining the time required for the second drying according to the weight grade of the clothes after dehydration, a dryness threshold is determined according to the weight grade of the clothes. When the drying program is completed according to the second drying time, it is determined whether the drying parameters meet the dryness threshold, such as whether the humidity is lower than the set value. If the dryness threshold is not met, the drying time is extended until the drying conditions are met, thereby improving the drying energy efficiency and ensuring the drying effect.

[0012] In some embodiments of the present invention, the dehydration process is performed at the highest speed in step S2.

[0013] After a drying process is performed, the clothes are partially dried and loosened, and can be evenly distributed, thus avoiding the occurrence of eccentricity. The highest speed can be reached directly to implement dehydration, thereby improving the dehydration effect.

[0014] The present invention also provides a clothes processing device, which is equipped with a drying program, comprising: A primary drying control unit, used to start and execute the drying program according to the set duration; A dehydration control unit, used for executing a dehydration program after a drying cycle; A weighing unit, used to weigh the clothes after the dehydration process is completed; A weighing and grading unit, used to determine the weight grade of the clothes according to the weight of the clothes; A drying parameter determination unit, used to determine the secondary drying time according to the weight grade; The secondary drying control unit is used to execute the drying program again with the secondary drying time.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: in the clothes processing device proposed by the present invention, when the clothes processing device starts the drying function, the first drying program is first executed according to the set time. The moisture content of the clothes is reduced through the first drying, and at the same time, the eccentric distribution of clothes due to different materials can be reduced, so as to achieve the effect of loosening and balancing the clothes, which is beneficial to the distribution of clothes during subsequent dehydration and avoids the occurrence of eccentricity; after the drying for the set time, a dehydration is performed to further reduce the moisture content of the clothes, which can improve the energy efficiency of the subsequent second drying, and because the drying for the set time has been performed once in the early stage, the uneven distribution caused by the difference in water absorption of the clothes is reduced, thereby improving the dehydration efficiency. The maximum speed of water is determined by the weight of the clothes. In this case, dehydration can be performed at the maximum speed after dehydration is performed again, so that more water can be thrown out of the clothes with higher moisture content after the first drying, and the situation that some clothes with low moisture content have been dried and some clothes with high moisture content have not been dried after the drying is completed is reduced, so that the moisture content of all clothes tends to be balanced; then the dehydrated clothes can be weighed more accurately, and the duration of the second drying can be set according to the accurate weighing classification, which can reduce the occurrence rate of over-drying or under-drying, thereby improving the drying effect; through the drying control proposed in the present invention, the maximum speed that can be achieved by dehydration can be increased, thereby reducing the moisture content of the clothes to be dried, thereby reducing the time required for drying, and improving the energy efficiency of drying.

[0016] In some embodiments of the present invention, the device further comprises: The first drying time determination unit is used to call the weighing unit to perform weighing after the dehydration process of the washing program is completed, and determine the set time according to the weighing.

[0017] In some embodiments of the present invention, the device further comprises: The second determination unit for a drying time is used to obtain the maximum dehydration speed after the dehydration process of the washing program is completed, and determine the set time according to the maximum dehydration speed.

[0018] In some embodiments of the present invention, the drying parameter determination unit is further used for: The dryness judgment threshold is determined according to the weight grade, so that the secondary drying control unit determines whether to end the secondary drying based on the dryness judgment threshold when the secondary drying time is reached, implements drying cooling when the dryness judgment threshold is met, and determines to extend the drying time based on the difference with the dryness judgment threshold when the dryness judgment threshold is not met, and continues to execute the drying program with the extended drying time.

[0019] In some embodiments of the present invention, the dehydration control unit performs a dehydration procedure at a maximum speed after one drying.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0027] The drying effect depends on many factors, the most direct of which is the drying time. In the past, the drying time consisted of two parts: (1) the drying threshold in the drying judgment logic; and (2) the maximum drying setting time. The setting of these two parts is based on the weight classification after the final dehydration of washing. In principle, the heavier the clothes, the longer the drying time required, and the stricter the drying threshold in the drying judgment logic; the lighter the clothes, the shorter the drying time required, and the wider the drying threshold in the drying judgment logic.

[0028] The applicant also analyzed that in clothing processing equipment such as a washer-dryer, the maximum speed of the final dehydration of washing also affects the drying time. The lower the maximum speed, the higher the moisture content of the clothes, the longer the drying time, and the stricter the dryness judgment threshold in the drying judgment logic; the higher the maximum speed, the lower the moisture content of the clothes, the shorter the drying time, and the wider the dryness judgment threshold in the drying judgment logic.

[0029] Therefore, in a washer-dryer, in principle, the lower the maximum speed and the heavier the clothes, the longer the drying time required, and the stricter the dryness threshold in the drying judgment logic; the higher the maximum speed and the lighter the clothes, the shorter the drying time required, and the wider the dryness threshold in the drying judgment logic.

[0030] That is, when other factors remain unchanged, the higher the maximum speed and the more accurate the weighing divisions, the shorter the drying time will be and the better the drying effect will be.

[0031] In the existing general drying scheme, the maximum speed of the final dehydration of washing is affected by the difference in the number of clothes, weight, water absorption and material, resulting in that the eccentricity value is difficult to be distributed very evenly within a limited number of distribution attempts during dehydration, and it is difficult to ensure that the maximum speed is reached during dehydration, which affects the moisture content of the clothes during drying. The drying effect can only be guaranteed by extending the drying time.

[0032] On the other hand, in the existing common drying scheme, the drying weighing grading is carried out after the final dehydration of washing is completed. Affected by the maximum speed of the final dehydration, the moisture content of the clothes after dehydration may be relatively high. In order to ensure the final drying effect of the clothes, the weighing grading is relatively wide, which will aggravate the situation of over-drying or under-drying.

[0033] In response to the problems of common drying solutions, the present invention adjusts the dehydration and drying strategies, improves the dehydration effect before weighing and grading, increases the probability of dehydration reaching the highest speed, and reduces the moisture content of clothes, thereby reducing the drying time while achieving accurate grading and improving the drying effect.

[0034] Specifically, Figure 1 As shown, the drying control method for a clothes processing device proposed by the present invention includes: S1: Start the drying process and execute it for the set duration.

[0035] Taking a condensing washer-dryer as an example, the drying program is started after washing and dehydration; of course, the present invention is not limited to a washing and drying system, and a dryer that only performs a drying function and starts the drying program after putting wet clothes to be dried is also within the protection scope of the present invention.

[0036] The set duration may be a specified fixed duration or a duration derived according to the state of the clothing, which will be specifically described in subsequent embodiments.

[0037] After starting the drying program, the present invention first executes the first drying program according to the set duration. The moisture content of the clothes is reduced through the first drying. At the same time, the eccentric distribution of clothes due to different materials can be reduced, so as to achieve the effect of loosening and balancing the clothes, which is beneficial to the distribution of clothes during subsequent dehydration and avoids the occurrence of eccentricity.

[0038] S2: Execute the dehydration program and weigh the clothes after the dehydration program is completed.

[0039] After executing the first drying for the set time, the clothing processing equipment switches to the dehydration program to implement a dehydration, so as to further reduce the moisture content of the clothes, so as to improve the energy efficiency of the subsequent second drying. Since the drying for the set time has been performed once in the previous stage, the uneven distribution caused by the difference in water absorption of the clothes is reduced, so that the maximum dehydration speed can be increased. In this case, after executing the dehydration again, the dehydration can be implemented at the highest speed, so that more water can be thrown out of the clothes with higher moisture content after the first drying, and the situation where some clothes with low moisture content have been dried and some clothes with high moisture content have not been dried after the drying is completed is reduced, so that the moisture content of all clothes tends to be balanced.

[0040] After dehydration, the dehydrated clothes can be weighed, and the moisture content in the weighing is low, so the weighing is more accurate.

[0041] S3: Determine the weight class of the clothes according to the weight of the clothes.

[0042] The more accurate the weighing of the clothes after dehydration, the more accurate the determination of their weight class. For example, if the dehydration is not thorough, the weight of the clothes will be very different from the actual weight of the clothes, and the assigned weight class will be wrong, resulting in inaccurate judgment of the subsequent drying time. The weight class here is divided into several intervals according to the weight nodes, for example, 0-1Kg is the first weight class, 1-3Kg is the second weight class, 3-5Kg is the third weight class, etc.

[0043] S4: Determine the secondary drying time according to the weight grade.

[0044] Setting the duration of the second drying according to precise weighing and grading can reduce the incidence of over-drying or under-drying, thereby improving the drying effect.

[0045] S5: Execute the drying process again with the second drying time.

[0046] After the drying process is complete, cool as usual.

[0047] As described above, after the drying function is started, the present invention first performs timed drying according to the set time, then performs dehydration once, and weighs and grades the clothes during dehydration. Different drying times are set according to the maximum speed reached by dehydration and the weighing grades, so as to ensure the drying effect while not wasting energy.

[0048] The following is a detailed description of the application of the drying control method proposed in the present invention in a clothing processing device using two specific embodiments.

[0049] Take a washer-dryer as an example. Figure 2 As shown, the following steps are included: S21: The washer-dryer starts the washing program.

[0050] S22: After the washing and dehydration is completed, the highest rotation speed reached during the dehydration is obtained.

[0051] Due to factors such as the material of the clothes, the clothes are unevenly distributed in the drum after washing, resulting in eccentricity. Especially when the clothes are heavy, it will affect the maximum speed during dehydration. When the eccentricity is more serious, the maximum speed cannot reach the ideal maximum speed, which will affect the dehydration effect. The present invention uses the maximum speed reached during washing and dehydration as a determining factor for the subsequent drying time.

[0052] S23: Determine the set time for executing the first drying according to the maximum spin speed.

[0053] In this embodiment, after the dehydration process of the previous washing program is completed, the highest speed reached during the dehydration period is obtained, and the set time is determined according to the highest speed that can be reached for dehydration. The higher the maximum speed, the shorter the set time, and the lower the maximum speed, the longer the set time. The purpose is to allow the clothes to be initially dried and at the same time achieve a loose and balanced distribution effect through drying for a set time. Especially when the clothes are heavier, the more serious the uneven distribution of the clothes during washing and dehydration, the greater the risk of eccentricity, and the lower the possibility of reaching the maximum speed during dehydration. In this case, the moisture content of the clothes after dehydration is higher, resulting in more energy consumption and time during drying. This embodiment determines the set time for the first drying by obtaining the maximum speed reached during dehydration after washing and dehydration, so as to loosen the clothes after the first drying, change the distribution state of the clothes during the drying rotation, and make the clothes more evenly distributed, thereby helping to reach the maximum speed in the subsequent dehydration process, so that more water can be thrown out of the clothes through dehydration, which helps to perform more accurate weighing after dehydration. A more accurate second drying time can be determined through more accurate weighing, so as to avoid the situation where some clothes with low moisture content in the drum have been dried after the drying is completed, while some clothes with high moisture content have not been dried.

[0054] S24: Start the drying program and execute it for the set time.

[0055] Perform the first drying according to the fixed set time. The moisture content of the clothes can be reduced through the first drying. At the same time, it can also reduce the eccentric distribution of clothes due to different materials, so as to achieve the effect of loosening and balancing the clothes, which is beneficial to the distribution of clothes during subsequent dehydration and avoids eccentricity.

[0056] S25: Execute the dehydration process at the highest speed, and weigh the clothes for the second time after the dehydration process is completed.

[0057] After executing the first drying for the set duration, the clothing processing equipment switches to the dehydration program to implement a dehydration, further reducing the moisture content of the clothes, in order to improve the energy efficiency of the subsequent second drying. Since the drying for the set duration has been performed once in the previous stage, the uneven distribution caused by the difference in water absorption of the clothes is reduced, and the occurrence of eccentricity is eliminated. In this case, after executing the dehydration again, the dehydration can be implemented at the highest speed, so that more water can be thrown out of the clothes with a higher moisture content after the first drying, and the situation where some clothes with low moisture content have been dried and some clothes with high moisture content have not been dried after the drying is completed is reduced, so that the moisture content of all clothes tends to be balanced.

[0058] After dehydration, the dehydrated clothes are weighed a second time. At this time, the moisture content of the clothes is lower, so the weighing is more accurate.

[0059] S26: Determine the weight class of the clothes according to the weight of the clothes.

[0060] The more accurate the weighing of the clothes after dehydration, the more accurate the weight class is. S27: Determine the secondary drying time and dryness threshold according to the weight grade.

[0061] Setting the duration of the second drying according to precise weighing and grading can reduce the incidence of over-drying or under-drying, thereby improving the drying effect.

[0062] The dryness determination threshold in this embodiment is a threshold of a parameter that can characterize the drying effect, such as a humidity threshold.

[0063] S28: Execute the drying process again with the secondary drying time.

[0064] S29: When the secondary drying time is reached, it is determined whether the drying can be ended according to the drying threshold.

[0065] When the dry threshold is met, the cooling step S31 is executed; if not, step S30 is executed.

[0066] S30: Determine the difference between the dryness threshold and the dryness threshold, determine the extended drying time based on the difference, and execute the drying program with the extended drying time.

[0067] S31: Exit the drying program after cooling.

[0068] Steps S29 to S30 may be repeated until the drying condition is met and then the drying procedure is exited.

[0069] The following embodiments take a clothes dryer as an example. Figure 3 As shown, the following steps are included: S41: The user puts the washed wet clothes into the dryer.

[0070] S42: Implement the first weighing.

[0071] The first weighing is implemented with existing pressure sensors or motor current feedback.

[0072] S43: Determine the set time for performing the first drying according to the weighing.

[0073] In this embodiment, a weighing is performed after the wet clothes are placed in the dryer, and the set time is determined according to the weighing result. The heavier the clothes, the longer the set time, and the lighter the clothes, the shorter the set time. The purpose is to allow the clothes to be initially dried and at the same time achieve a loose and evenly distributed effect through drying for a set time. Especially when the clothes are heavy, after washing and dehydrating in the early stage of the washing machine, there is a certain difference in the moisture content of the clothes in different positions. This is because under the action of centrifugal force, the closer the clothes are to the drum wall, the greater the centrifugal force is, and the more water is thrown out. On the contrary, the closer the clothes are to the center of the drum, the less water is thrown out due to the small centrifugal force. This leads to uneven moisture content of the wet clothes put into the dryer; when the wet clothes with uneven moisture content are put into the dryer, this embodiment determines the set time of the first drying by weighing, so as to loosen the clothes after the first drying, and change the distribution state of the clothes during the drying rotation to make the clothes evenly distributed, so as to help reach the highest speed in the subsequent dehydration process, so that more water can be thrown out of the clothes with higher moisture content through dehydration, and it is helpful to perform more accurate weighing, and determine a more accurate second drying time by more accurate weighing, so as to avoid the situation that some clothes with low moisture content in the drum have been dried after the drying is completed, while some clothes with high moisture content have not been dried.

[0074] S44: Start the drying program and execute it for the set time.

[0075] Perform the first drying according to the fixed set time. The moisture content of the clothes can be reduced through the first drying. At the same time, it can also reduce the eccentric distribution of clothes due to different materials, so as to achieve the effect of loosening and balancing the clothes, which is beneficial to the distribution of clothes during subsequent dehydration and avoids eccentricity.

[0076] S45: Execute the dehydration process at the highest speed, and weigh the clothes for the second time after the dehydration process is completed.

[0077] After executing the first drying for the set duration, the clothing processing equipment switches to the dehydration program to implement a dehydration, further reducing the moisture content of the clothes, in order to improve the energy efficiency of the subsequent second drying. Since the drying for the set duration has been performed once in the previous stage, the uneven distribution caused by the difference in water absorption of the clothes is reduced, and the occurrence of eccentricity is eliminated. In this case, after executing the dehydration again, the dehydration can be implemented at the highest speed, so that more water can be thrown out of the clothes with a higher moisture content after the first drying, and the situation where some clothes with low moisture content have been dried and some clothes with high moisture content have not been dried after the drying is completed is reduced, so that the moisture content of all clothes tends to be balanced.

[0078] After dehydration, the dehydrated clothes are weighed a second time. At this time, the moisture content of the clothes is lower, so the weighing is more accurate.

[0079] S46: Determine the weight class of the clothes according to the weighing of the clothes.

[0080] The more accurate the weighing of the clothes after dehydration, the more accurate the weight class is. S47: Determine the secondary drying time and dryness threshold according to the weight grade.

[0081] Setting the duration of the second drying according to precise weighing and grading can reduce the incidence of over-drying or under-drying, thereby improving the drying effect.

[0082] The dryness determination threshold in this embodiment is a threshold of a parameter that can characterize the drying effect, such as a humidity threshold.

[0083] S48: Execute the drying process again with the secondary drying time.

[0084] S49: When the secondary drying time is reached, it is determined whether the drying can be ended according to the drying threshold.

[0085] When the dry threshold is met, the cooling step of S51 is executed; if not, step S50 is executed.

[0086] S50: Determine the difference between the dryness threshold and the dryness threshold, determine the extended drying time based on the difference, and execute the drying procedure based on the extended drying time.

[0087] S51: Exit the drying program after cooling.

[0088] Steps S49 to S50 may be repeated until the drying condition is met and then the drying procedure is exited.

[0089] Based on the drying control method given above, the present invention also proposes a clothes processing device, which is equipped with the drying control method given above, such as Figure 4 As shown, including: The primary drying control unit 41 is used to start and execute the drying program according to the set duration.

[0090] The dehydration control unit 42 is used to execute a dehydration program after a drying process.

[0091] The weighing unit 43 is used to weigh the clothes after the dehydration process is completed.

[0092] The weighing and grading unit 44 is used to determine the weight grade of the clothes according to the weighing of the clothes.

[0093] The drying parameter determination unit 45 is used to determine the secondary drying time according to the weight grade.

[0094] The secondary drying control unit 46 is used to execute the drying program again with the secondary drying time.

[0095] In some embodiments of the present invention, the clothes processing device further includes: The first drying time determination unit 47 is used to call the weighing unit to perform weighing after the dehydration process of the washing program is completed, and determine the set time according to the weighing.

[0096] In some embodiments of the present invention, the clothes processing device further includes: The second drying time determination unit 48 is used to obtain the maximum spin speed after the spin process of the washing program is completed, and determine the set time according to the maximum spin speed.

[0097] In some embodiments of the present invention, the drying parameter determination unit 45 is also used to determine a dryness threshold according to the weight grade, so that the secondary drying control unit 46 determines whether to end the secondary drying based on the dryness threshold when the secondary drying time is reached, implements drying cooling when the dryness threshold is met, and determines to extend the drying time based on the difference with the dryness threshold when the dryness threshold is not met, and continues to execute the drying program with the extended drying time.

[0098] In some embodiments of the present invention, the dehydration control unit 42 performs a dehydration procedure at the highest speed after one drying.
