Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0046] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0047] 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 construed 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. The washing machine may include but is not limited to a washing and care machine, a washing and drying machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with drying or washing and care functions, and of course, the washing machine may also be other types of fully automatic washing machines. The clothes dryer may include but is not limited to a condensing clothes dryer or a direct-discharge clothes dryer.

[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 arranged in the washer-dryer (ie, fabric treatment device), and the fabric treatment drum may include a drum or a rotating drum, and the clothes can be washed or dried by the fabric treatment drum.

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

[0052] A drying fan, a drying element and a filter are arranged in the drying air duct, and 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 fin tube, etc.

[0053] Among them, when the washer-dryer is powered on and runs the drying program, the drying part heats the air. Under the action of the drying fan, the heated air forms a drying airflow, which flows along the drying air duct and then enters the fabric treatment drum through the air inlet to dry the clothes in the fabric treatment drum, and the free water and bound water in the clothes form hot and humid air. Finally, the humid air enters the drying air duct through multiple air inlets, and the water molecules in the humid air are removed by the heating and drying of the drying part. The treated air is introduced into the fabric treatment drum again by the drying fan to continue drying the fabric, and this process is repeated to achieve the drying of the fabric.

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

[0055] Among them, when the moisture content of the fabric drops from a high value to a dry state, the filter screen is blocked at the fastest speed. Therefore, based on the blocking speed of the filter screen, a logical judgment can be made on the dry state of the fabric in the later stage of drying.

[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 airflow and the flow rate of the next drying airflow are calculated to determine the change in flow rate, which is the difference between the flow rate of the previous drying airflow and the flow rate of the next drying airflow.

[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 under-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. The moisture content of the fabric is obtained by dividing the value by the dry weight of the fabric.

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

[0061] To avoid the situation where fabrics are not dried or over-dried in a 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 can run 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 processing 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 the first correction parameter and the material information of the fabric according to the actual heating time and the rotation speed of the fabric processing drum during the heating stage.

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

[0070] The control system first determines the theoretical material coefficient according to 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 according to 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 and the moisture content after dehydration of the fabric of this material. 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 a constant temperature and constant humidity laboratory environment is set for the environmental conditions to eliminate external interference. The test process to obtain repeatable results 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, and the specific structure type and specific control logic of the control system will not be repeated here.

[0073] It should be noted that under the 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, the first correction parameter is determined according to 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 the first set value is used as the first correction coefficient, wherein 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] According to 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, 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] According to the material information and weight information of the fabric, the theoretical heating time may be longer or shorter than the actual heating time. For example, when the fabric weight is not accurate in kilograms, the theoretical heating time may be longer or shorter than the actual heating time.

[0082] Then, the 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, wherein 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 after the material information of the fabric is determined, the theoretical drying time of a single material at different kilogram levels is derived according to the calculation process of the European standard load. Based on this, the theoretical drying time of fabrics 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, but instead 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 enhancing 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 by 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 completed the heating stage, the theoretical material coefficient K can be determined according to the rotation 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, we can directly determine the theoretical material coefficient K 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 factor 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 according to the moisture content and the rotation 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 is 实It is the quotient of water content and rotation speed.

[0096] Refer to the following Table 1 and Table 2 to get the actual material coefficient K of a single material fabric. 实 , where 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 Corresponding parameter table.

[0098] Table 1

[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 material of the fabric may include cotton, linen, chemical fiber, denim, wool, etc., that is, the fabric of mixed materials may include any combination of the above-mentioned 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 T of the fabric in the heating stage is 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 at 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 1Kg and 2Kg, the theoretical heating time T may be 升 Than the actual heating time 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, and the second difference 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, in the process of drying the fabric using the modified drying time, in order to improve the accuracy of judging the drying state of the fabric, the clogging speed of the filter in the drying duct can be used for logical judgment.

[0114] As hair debris gradually accumulates on the filter, the filter clogs the drying air duct faster and faster.

[0115] Among them, when the moisture content of the fabric drops from a high value to a dry state, the filter screen is blocked at the fastest speed. Therefore, based on the blocking speed of the filter screen, a logical judgment can be made on the dry state of the fabric in the later stage of drying.

[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 airflow and the flow rate of the next drying airflow are calculated to determine the change in flow rate, which is the difference between the flow rate of the previous drying airflow and the flow rate of the next drying airflow.

[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 under-dried or over-dried.

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

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

The drying program includes a heating stage and a drying stage. The drying control method includes: first, obtaining the actual heating time of the fabric after the heating stage is completed; then, according to the actual heating time and the rotation speed of the fabric processing drum, determining a first correction parameter and the material information of the fabric, and determining a second correction parameter according to the material information of the fabric and the actual heating time; then, 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 the corrected drying time; finally, using the corrected drying time as the drying time of the drying stage, and drying the fabric.
