In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0047] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0048] An exemplary embodiment of the present invention provides a fabric processing device, which may include, but is not limited to, a washing machine or a clothes dryer. Washing machines may include, but are not limited to, all-in-one washing and care machines, all-in-one washing and drying machines, and the like. For example, a washing machine may be a drum washing machine or a pulsator washing machine with drying or washing and care functions. Of course, the washing machine may also be other types of fully automatic washing machines. Clothes dryers may include, but are not limited to, condensing dryers or direct-discharge dryers.

[0049] In this example and the following examples, the fabric processing device is a washer-dryer as an example.

[0050] A fabric treatment drum is provided in the washer-dryer (ie, a fabric treatment device), and the fabric treatment drum may include a drum or a rotating drum, and the fabric treatment drum can be used to wash or dry clothes.

[0051] A drying air duct is provided in the washer-dryer, the air outlet of the drying air duct is connected to the interior of the fabric processing drum, and the drying air duct has at least one air inlet, which is also connected to the interior of the fabric processing drum.

[0052] A drying fan, a drying element, and a filter are provided in the drying air duct. The drying element can be located downstream of the drying fan along the flow direction of the drying airflow, that is, from the air inlet to the air outlet. The drying element can include but is not limited to an electric heating tube, a finned tube, and the like.

[0053] When the washer-dryer is powered on and the drying cycle is running, the drying element heats the air. Under the action of the drying fan, the heated air forms a dry airflow, which flows along the drying duct. The dry airflow then enters the fabric treatment drum through the air inlet to dry the clothes in the fabric treatment drum, converting the free water and bound water in the clothes into hot and humid air. Finally, the humid air enters the drying duct through multiple air inlets. The drying element heats and dries the humid air, removing the water molecules. The treated air is then introduced into the fabric treatment drum again by the drying fan to continue drying the fabric. This process is repeated, thereby achieving the drying of the fabric.

[0054] The filter is arranged in the drying air duct, and is used to intercept the hair scraps that fall off the fabric during the drying process. In the specific use process, as the hair scraps gradually accumulate on the filter, the filter will block the drying air duct faster and faster.

[0055] Among them, when the fabric drops from a high moisture content to a dry state, the filter will clog the fastest. Therefore, based on the filter clogging rate, the dryness of the fabric in the later stage of drying can be logically judged.

[0056] The specific logical judgment process is: when the fabric processing equipment is running the drying program, the flow rate of the drying air delivered to the fabric processing drum is detected in real time. As the filter becomes blocked faster, the flow rate of the drying air delivered to the fabric processing drum becomes lower and lower.

[0057] At each set time interval, the flow rate of the previous drying air flow and the flow rate of the next drying air flow are calculated to determine the change in flow rate, which is the difference between the flow rate of the previous drying air flow and the flow rate of the next drying air flow.

[0058] When the change in flow rate is greater than or equal to a preset threshold, the surface fabric has reached an ideal dry state, and the drying process can be ended at this time to avoid the fabric being not dried or over-dried.

[0059] Fabrics of different materials have different amounts of residual water after dehydration, that is, different moisture contents. The moisture content of the fabric is obtained by subtracting the weight of the fabric after dehydration from the dry weight of the fabric. This value is divided by the dry weight of the fabric.

[0060] Because fabrics of different materials and of the same mass have different moisture contents after being dehydrated at the same speed, the temperature impact on the entire drying system is also different. The use of the existing technology of using temperature sensors to judge the dryness may easily cause some fabrics to not be dried or over-dried, thereby causing the drying gear of the entire fabric processing equipment to be disordered, affecting the drying effect of the fabric.

[0061] In order to avoid the situation that the fabrics are not dried or over-dried in the washer-dryer, Figure 1 As shown, an exemplary embodiment of the present invention provides a drying control method, which is applied to a fabric processing device, wherein the fabric processing device includes a fabric processing drum, and the fabric processing device is capable of running a drying program to dry the fabric in the fabric processing drum, wherein the drying program includes a heating stage and a drying stage.

[0062] The drying control method comprises the following steps:

[0063] Step S100: obtaining the actual heating time after the heating phase is completed.

[0064] Step S200: determining a first correction parameter and fabric material information based on the actual heating time and the rotation speed of the fabric treatment drum, and determining a second correction parameter based on the fabric material information and the actual heating time.

[0065] Step S300: correcting the theoretical drying time of the fabric in the drying stage according to the first correction parameter and the second correction parameter to obtain a corrected drying time.

[0066] Step S400: using the corrected drying time as the drying time of the drying stage to dry the fabric.

[0067] Wherein, in step S100, after the fabric processing device completes the heating stage, the actual heating time of the entire heating stage can be obtained through the fabric processing device.

[0068] In step S200, the control system of the fabric processing device determines a first correction parameter and fabric material information according to the actual heating time and the rotation speed of the fabric processing drum during the heating stage.

[0069] The first correction parameter can be determined by the following method:

[0070] The control system first determines the theoretical material coefficient based on the actual heating time and rotation speed. It should be noted that the theoretical material coefficient can be pre-stored in the control system. After the fabric treatment drum has completed the heating stage, the theoretical material coefficient can be determined based on the rotation speed of the fabric treatment drum during the heating stage and the actual heating time. Among them, the theoretical material coefficient of the fabric is used to characterize the relationship between the dehydration speed of the fabric of this material and the moisture content after dehydration. The theoretical material coefficient of the fabric can be determined based on the calculation under the European standard load. Among them, the European standard load is a standardized test procedure in the prior art. The fabric samples used in the standardized test include different types such as pure cotton and blended fabrics to simulate actual clothing combinations; and the environmental conditions are set to a constant temperature and constant humidity laboratory environment to eliminate external interference to obtain repeatable results. The test process will not be repeated here.

[0071] Once the theoretical material coefficient is determined, the material information of the fabric corresponding to the theoretical material coefficient can be directly determined.

[0072] The control system of the washer-dryer can adopt the control system in the existing technology, as long as the control system can control various startup functions of the washer-dryer. The specific structure type and specific control logic of the control system will not be repeated here.

[0073] It should be noted that under European standard load, fabrics made of a single material have a certain theoretical material coefficient at different kilogram levels. Based on this, the theoretical material coefficients of fabrics made of multiple mixed materials at different kilogram levels can be derived.

[0074] Among them, the kilogram grades under European standard load are divided into 0.5Kg, 1Kg, 2Kg, 3Kg, 4Kg, 5Kg, 6Kg, 7Kg, etc.

[0075] Then, the actual material coefficient of the fabric in the drying stage is determined. Specifically, the moisture content of the fabric after dehydration before the drying process can be obtained first, and the actual material coefficient can be determined based on the moisture content and the rotation speed of the fabric treatment drum during the heating stage.

[0076] The quotient of moisture content and rotation speed is taken as the actual material coefficient of the fabric in the drying stage.

[0077] Finally, a first correction parameter is determined based on the actual material coefficient and the theoretical material coefficient. Specifically, the difference between the actual material coefficient and the theoretical material coefficient is defined as a first difference, the first difference is divided by the theoretical material coefficient to obtain a quotient, and the sum of the quotient and a first set value is used as the first correction coefficient, where the first set value is 1.

[0078] After the material information of the fabric is determined, the second correction parameter is determined according to the actual heating time and the material information.

[0079] The process of determining the second correction parameter includes:

[0080] Based on the material information of the fabric in the fabric treatment drum, the theoretical heating time of the fabric in the heating stage can be determined. It should be noted that the theoretical heating time of the fabric in the heating stage can be determined through the calculation process of the European standard load. That is to say, under the European standard load, a single material has a certain theoretical heating time at various kilogram levels, and multiple mixed fabrics also have a certain theoretical heating time at various kilogram levels.

[0081] Depending on the material and weight of the fabric, the theoretical heating time may be longer or shorter than the actual heating time. For example, if the fabric weight is not accurate in kilograms, the theoretical heating time may be longer or shorter than the actual heating time.

[0082] Then, a second correction parameter is determined according to the theoretical heating time and the actual heating time.

[0083] Specifically, the difference between the actual heating time and the theoretical heating time is defined as the second difference, the second difference is divided by the theoretical heating time to obtain a quotient, and the sum of the quotient and the second set value is used as the second correction coefficient, where the second set value is 1.

[0084] In step S300, the first correction coefficient, the second correction coefficient and the theoretical drying time of the fabric in the drying stage are multiplied respectively to obtain the product of the first correction coefficient, the second correction coefficient and the theoretical drying time, and the product is used as the corrected drying time.

[0085] It should be noted that once the fabric material information is determined, the theoretical drying time of a single material at different kilogram levels is derived based on the calculation process of the European standard load. Based on this, the theoretical drying time of fabrics made of multiple mixed materials at different kilogram levels can be derived.

[0086] In step S400, the corrected drying time is used as the drying time of the fabric in the drying stage, and the fabric is dried.

[0087] In this example, after the heating stage is completed, the control system does not immediately give the subsequent drying time for the fabric. Instead, it corrects the theoretical drying time of the fabric in the drying stage at least twice based on the actual heating time and rotation speed in the heating stage, and uses the corrected drying time as the drying time of the fabric in the drying stage, thereby providing a more accurate drying time for the fabric in the drying stage, effectively ensuring the drying effect of the fabric, and improving the user experience of the fabric processing equipment.

[0088] like Figure 2 As shown, in some embodiments, the first correction parameter and the second correction parameter may be determined using the following method.

[0089] The process of determining the first correction parameter includes:

[0090] The control system first determines the theoretical material coefficient K based on the actual heating time and speed. 理 It should be noted that the theoretical material coefficient K 理 It can be pre-stored in the control system. After the fabric treatment drum has finished the heating stage, the theoretical material coefficient K can be determined based on the speed of the fabric treatment drum during the heating stage and the actual heating time. 理 , where the theoretical material coefficient K of the fabric is 理 Used to characterize the relationship between the dehydration speed of the fabric and its moisture content after dehydration.

[0091] When the theoretical material coefficient K is determined 理 After that, the theoretical material coefficient K can be directly determined 理 The corresponding fabric material information.

[0092] It should be noted that under the European standard load, a single material fabric has a certain theoretical material coefficient K at different kilogram levels. 理 ,Based on this, the theoretical material coefficients of various mixed material fabrics at different kilogram levels can be derived.

[0093] Among them, the kilogram grades under European standard load are divided into 0.5Kg, 1Kg, 2Kg, 3Kg, 4Kg, 5Kg, 6Kg, 7Kg, etc.

[0094] Then, determine the actual material coefficient K of the fabric during the drying stage 实 Specifically, the moisture content of the fabric after dehydration before the drying process can be obtained first, and the actual material coefficient K can be determined based on the moisture content and the speed of the fabric treatment drum during the heating stage. 实 .

[0095] Among them, the actual material coefficient K of the fabric in the drying stage 实It is the quotient of water content and rotation speed.

[0096] Refer to Table 1 and Table 2 below to get the actual material coefficient K of a single material fabric. 实 Table 1 is the corresponding parameter table of dehydration speed and moisture content of fabrics of a single material at different kilogram levels. Table 2 is the corresponding parameter table of dehydration speed and actual material coefficient K of fabrics of a single material at different kilogram levels. 实 The corresponding parameter table.

[0099]

[0100] Table 2

[0101] The actual material coefficient K of the single material fabric in Table 2 above 实 The actual material coefficient K of fabrics of various mixed materials can be derived 实 .

[0102] It should be noted that the materials of the fabric may include cotton, linen, chemical fiber, denim, wool, etc., that is, the mixed material fabric may include any combination of the above material types.

[0103] Finally, according to the actual material coefficient K 实 And theoretical material coefficient K 理 , determine the first correction parameter A. Specifically, define the actual material coefficient K 实 And theoretical material coefficient K 理 The difference is the first difference, which is divided by the theoretical material coefficient K 理 A quotient is obtained, and the sum of the quotient and a first set value is used as a first correction coefficient, wherein the first set value is 1.

[0104] That is, the first correction parameter A=(1+(K 实 -K 理) ) / K 理 ), it should be noted that K in this example 实 It can be the actual material coefficient of a fabric of a single material, or it can be the actual material coefficient of a fabric of mixed materials derived from Table 2.

[0105] The process of determining the second correction coefficient includes:

[0106] According to the material information of the fabric in the fabric treatment drum, the theoretical heating time T of the fabric in the heating stage can be determined. 升It should be noted that the theoretical heating time of the fabric in the heating stage is T 升 It can be determined through the calculation process of the European standard load. That is to say, under the calculation derivation of the European standard load, a single material has a certain theoretical heating time T under various kilogram levels. 升 Based on this, after logical deduction of various mixed material fabrics, various mixed fabrics also have a certain theoretical heating time T under various kilogram levels. 升 .

[0107] According to the material and weight information of the fabric, the theoretical heating time T 升 Can be longer than the actual heating time T 实 More or less. For example, when the fabric weight is not accurate in kilograms, for example, when the fabric weight is between 1 kg and 2 kg, the theoretical heating time T may be 升 Longer than the actual heating time T 实 More or less.

[0108] Then, according to the theoretical heating time T 升 and the actual heating time T 实 A second correction parameter is determined.

[0109] Specifically, the actual heating time T is defined as 实 and theoretical heating time T 升 The difference is the second difference, which is divided by the theoretical heating time T 升 A quotient is obtained, and the sum of the quotient and a second set value is used as a second correction coefficient B, wherein the second set value is 1.

[0110] That is, the second correction parameter B=(1+(T 实 -T 升) ) / T 升 ).

[0111] like Figure 2 As shown, in some embodiments, the first correction coefficient A, the second correction coefficient B and the theoretical drying time T of the fabric in the drying stage are calculated. 理 Multiply them respectively to get the first correction coefficient A, the second correction coefficient B and the theoretical drying time T 理 The product of the three is used as the corrected drying time T 烘 .

[0112] That is, the corrected drying time T 烘 =A times B times T 烘 =(1+(K 实 -K 理) ) / K 理 )×(1+(T 实 -T 升) ) / T升 )×T 理 .

[0113] like Figure 2 As shown, in some embodiments, when drying fabrics using a modified drying time, in order to improve the accuracy of judging the drying status of the fabrics, a logical judgment can be made using the clogging speed of the filter in the drying duct.

[0114] Among them, as the hair debris gradually accumulates on the filter, the filter blocks the drying air duct faster and faster.

[0115] Among them, when the fabric drops from a high moisture content to a dry state, the filter will clog the fastest. Therefore, based on the filter clogging rate, the dryness of the fabric in the later stage of drying can be logically judged.

[0116] The specific logical judgment process is: when the fabric processing equipment is running the drying program, the flow rate of the drying air delivered to the fabric processing drum is detected in real time. As the filter becomes blocked faster, the flow rate of the drying air delivered to the fabric processing drum becomes lower and lower.

[0117] At each set time interval, the flow rate of the previous drying air flow and the flow rate of the next drying air flow are calculated to determine the change in flow rate, which is the difference between the flow rate of the previous drying air flow and the flow rate of the next drying air flow.

[0118] When the change in flow rate is greater than or equal to a preset threshold, the surface fabric has reached an ideal dry state, and the drying process can be ended at this time to avoid the fabric being not dried or over-dried.

[0119] An exemplary embodiment of the present invention further provides an electronic device comprising a processor (not shown) and a memory (not shown) connected to the processor. The memory is configured to store one or more computer-executable instructions. The computer-executable instructions can be called by the processor to execute the drying control method of the above-described embodiment.

[0120] An exemplary embodiment of the present invention further provides a fabric processing device that is controlled by the drying control method of any of the above embodiments, or includes an electronic device of the above embodiments.

[0121] In this example, a fabric processing device includes a fabric processing drum, and the fabric processing device is capable of running a drying program to dry fabric within the fabric processing drum. The drying program includes a heating phase and a drying phase. The drying control method includes: first, obtaining an actual heating time of the fabric after the heating phase ends; then, determining a first correction parameter and fabric material information based on the actual heating time and the rotation speed of the fabric processing drum, and determining a second correction parameter based on the fabric material information and the actual heating time; then, correcting a theoretical drying time of the fabric in the drying phase based on the first correction parameter and the second correction parameter to obtain a corrected drying time; finally, using the corrected drying time as the drying time in the drying phase and drying the fabric. In the present invention, after the heating phase ends, the control system does not immediately set a subsequent drying time for the fabric. Instead, the control system corrects the theoretical drying time of the fabric in the drying phase at least twice based on the actual heating time and the rotation speed of the heating phase, and uses the corrected drying time as the drying time for the fabric in the drying phase. This provides a more accurate drying time for the fabric in the drying phase, effectively ensuring the drying effect of the fabric, and improving the user experience of the fabric processing device.
