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.

[0064] 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.

[0065] like Figure 1As shown, an exemplary embodiment of the present invention provides a laundry processing device 100. The laundry processing device may include, but is not limited to, a washing machine, which may include, but is not limited to, a washer-care all-in-one machine, a washer-dryer all-in-one machine, and the like. For example, the washing machine may be a drum washing machine or a pulsator washing machine with drying or washing functions. Of course, the washing machine may also be other types of fully automatic washing machines.

[0066] In this example and the following examples, the clothing processing device 100 is taken as an example of a washer-dryer.

[0067] The laundry processing device 100 includes a main body 110 and a laundry processing drum 120 disposed within the main body 110. A drying air duct 130 is disposed on the main body 110, and an air outlet 131 of the drying air duct 130 is connected to the interior of the laundry processing drum 120. The drying air duct 130 has a plurality of air inlets 132, which are also connected to the interior of the laundry processing drum 120.

[0068] A drying fan 133 and a drying element 134 are provided in the drying air duct 130. The drying element 134 is located downstream of the drying fan 133 along the flow direction of the drying airflow, i.e., from the air inlet 132 to the air outlet 131. The drying element 134 may include, but is not limited to, an electric heating tube, a finned tube, etc.

[0069] When the washer-dryer is powered on and the drying program is running, the drying unit 134 heats the air. Under the action of the drying fan 133, the heated air forms a drying airflow. The flow direction of the drying airflow is as follows: Figure 1 As shown by the arrows in the figure, the dry airflow flows along the drying duct 130 and then enters the laundry treatment drum 120 through the air inlet 132 to dry the clothes in the laundry treatment drum 120, converting the free water and bound water in the clothes into hot and humid air. Finally, the humid air enters the drying duct 130 through the multiple air outlets 131, where it is condensed to remove the water molecules in the humid air. The treated air is heated again by the drying element 134 and then re-enters the laundry treatment drum 120 to continue drying the clothes. This cycle is repeated to achieve the complete drying of the clothes.

[0070] The main body 110 is also provided with a condenser pipe 140 and a condensation valve 150. The condenser pipe 140 may have multiple water inlets 141. One of the water inlets 141 extends into the laundry tub 120 and is directly opposite the guide ribs 121 on the inner wall of the laundry tub 120. Condensed water entering through this water inlet 141 can flow directly onto the guide ribs 121, allowing the condensed water to enter the laundry tub 120 in a dispersed manner. The remaining water inlets 141 may be provided within the drying duct 130, thereby utilizing the water inlets 141 provided at these locations to condense water molecules in the humid air, thereby removing the water molecules from the humid air.

[0071] The condensation valve 150 is arranged on the condensation tube 140, wherein the water inlet rhythm of the condensation valve 150 is controlled by the control system of the washer-dryer to control the flow or flow rate of the condensation water in the condensation tube 140, thereby accurately controlling the flow or flow rate of the condensation water entering the clothing processing drum 120.

[0072] A drain port 122 is provided at the bottom of the laundry processing tub 120, and a control valve 180 or a drain pump is provided on a drainage pipeline connected to the drain port 122. During the drying process of the laundry processing tub 120, adaptive drainage can be achieved by turning on or off the control valve 180 or the drain pump.

[0073] During the clothes drying process, it is necessary to monitor the temperature at relevant locations within the clothes processing drum 120. For example, a first temperature sensor 123 is provided at the drain outlet 122 of the clothes processing drum 120, a second temperature sensor 124 is provided near the drying fan 133, and a third temperature sensor 125 is provided near the air inlet 132.

[0074] The first temperature detecting element 123 , the second temperature detecting element 124 , and the third temperature detecting element 125 may include, but are not limited to, temperature sensors, temperature and humidity sensors, etc. Furthermore, the first temperature detecting element 123 , the second temperature detecting element 124 , and the third temperature detecting element 125 may use the same sensor or different sensors.

[0075] It should be noted that the first temperature detector 123 is used to detect the temperature of the drain water from the laundry processing drum 120. The second temperature detector 124 is used to detect the return air temperature of the return air flow from the drying air duct 130. And, the third temperature detector 125 is used to detect the drying air flow temperature of the drying air flow entering the laundry processing drum 120.

[0076] In some embodiments, the first temperature detection element 123 is set at the lowest position of the water tank in the clothing processing drum 120, and the setting position of the second temperature detection element 124 is higher than the setting position of the first temperature detection element 123. For example, the second temperature detection element 124 can be set at a predetermined position below the suction port of the drying fan 133.

[0077] The location of the third temperature detection element 125 can be flexibly set according to the different locations of the air inlet 132 , and is not specifically limited here.

[0078] The main body 110 is also provided with a flushing pipe 160 and a flushing valve 170. The outlet end 161 of the flushing pipe 160 is connected to the interior of the drying duct 130. It should be noted that the flushing pipe 160 is used to flush blocked locations in the drying duct 130 or locations where hair debris is easily accumulated, thereby ensuring the patency of the drying duct 130.

[0079] like Figure 2 As shown, an exemplary embodiment of the present invention provides a drying control method for a clothes processing device, the drying control method comprising the following steps:

[0080] Step S100: During the drying process of the clothes processing drum, it is determined whether the drying duct is in an abnormal state.

[0081] Step S200: When the drying air duct is in an abnormal state, obtaining a first dehydration speed before the clothes processing drum runs a drying program.

[0082] Step S300: When the first dehydration speed is lower than the maximum dehydration speed of the clothes processing tub during dehydration, the clothes processing tub is controlled to perform secondary dehydration.

[0083] Step S400: Determine the drying parameters of the clothes according to the secondary dehydration information of the clothes processing drum.

[0084] In step S100, when the clothes in the clothes processing drum 120 need to be dried after being dehydrated, the control system of the clothes processing device 100 is first used to determine whether the drying duct 130 is in an abnormal state. For example, when there is blockage inside the drying duct 130 due to long-term use, it will affect the circulation of the drying airflow in the drying duct 130, thereby affecting the drying effect of the clothes.

[0085] Among them, 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.

[0086] In some embodiments, the drying process includes a drying temperature rise phase, wherein the inlet temperature of the laundry processing drum 120 (i.e., the air outlet 131 of the drying duct 130) is obtained based on the third temperature detecting element 125, and the outlet temperature of the laundry processing drum 120 (i.e., the air inlet 132 of the drying duct 130) is obtained based on the second temperature detecting element 124.

[0087] When the inlet temperature is outside the first threshold range and the outlet temperature is outside the second threshold range, the drying and heating phase is determined to be over. The first threshold range is [90°C, 100°C] and the second threshold range is [50°C, 60°C].

[0088] When the drying and heating stage is finished, first, the control system determines the execution time t of the drying and heating stage, or determines the temperature difference ΔT of the laundry processing drum 120, which is used to represent the inlet temperature T 进 and outlet temperature T 出 The difference between 进 -T 出 ).

[0089] Finally, when one of the following conditions is met, it is determined that the drying air duct 130 is in an abnormal state.

[0090] Condition 1: When the temperature difference ΔT is outside the preset difference range, it is determined that the drying air duct 130 is in an abnormal state. The preset difference range is [35° C., 50° C.].

[0091] Condition 2: When the execution time t is greater than the upper limit of the preset time range, it is determined that the drying duct 130 is in an abnormal state. The preset time range is [50 minutes, 60 minutes].

[0092] It should be noted that when the temperature difference ΔT is within the preset difference range, ie, [35° C., 50° C.], or when the execution time t is within the preset time range, it is determined that the drying duct 130 is in a normal state.

[0093] When the drying air duct 130 is in a normal state, the drying process continues and the clothes drying time is determined to be a fourth time t4. The fourth time t4 is positively correlated with the weight of the clothes after one dehydration in the clothes processing drum 120. That is, the heavier the weight of the clothes after one dehydration, the longer the fourth time t4.

[0094] In one example, the fourth time t4 can be determined by the following relationship: t4 = a4k + b4, where a4 and b4 are set values, the value range of a4 is [20, 27 s], and the value range of b4 is [10, 22]. Preferably, a4 = 25 and b4 = 20. The coefficient k is equal to the weight m of the laundry after one dehydration, that is, k = m.

[0095] During the remaining drying time of the fourth time t4, the control valve 180 is controlled based on the control system to drain water at a fourth drainage rhythm until the drying process is finished.

[0096] The process of drainage in the fourth drainage rhythm includes:

[0097] The start-stop ratio of the control valve 180 is b41:b42, where b41 is used to characterize the opening time of the control valve 180, and the value range of the opening time is [10s, 30s]; b42 is used to characterize the closing time of the control valve 180, and the value range of the closing time is [5s, 20s].

[0098] In a specific example, the value range of b41 is [20s, 25s], and the value range of b42 is [10s, 15s].

[0099] In step S200, during the drying process, if it is determined that the drying duct 130 is in an abnormal state, the flushing valve 170 may be opened and the drying fan 133 may be simultaneously turned on to flush the drying duct 130 for a predetermined time using the water in the flushing pipe 160 and the air from the drying fan 133 to remove any clogged material from the drying duct 130. The predetermined time may be 20 seconds.

[0100] It should be noted that in this example, the flushing valve 170 is controlled to open for 20 seconds to flush the drying duct 130. When the drying duct 130 is in a normal state, the flushing while blowing operation is not performed. The flushing valve 170 is only opened during the drainage process of each washing cycle to flush the drying duct 130 for about 10 seconds.

[0101] After the drying air duct 130 is flushed through the flushing valve 170 and the flushing pipe 160, or alternatively, the drying air duct 130 may not be flushed, the following operations are performed:

[0102] The control system obtains the first dehydration speed V1 before the laundry processing drum 120 runs the drying process, wherein the value range of the first dehydration speed V1 may include [1000 rpm, 1400 rpm].

[0103] In step S200 , after obtaining relevant parameters of the first dehydration speed V1 of the laundry processing drum 120 before the laundry processing drum 120 runs the drying program, the control system compares the relevant parameters with the maximum dehydration speed when the laundry processing drum 120 is dehydrating.

[0104] When the parameters related to the first spin speed V1 are greater than or equal to the maximum spin speed Vmax, it indicates that the clothes in the laundry treatment drum 120 have been spun at the maximum spin speed and the moisture content in the clothes has reached the minimum value, and no secondary spin is required. At this time, the control system determines that the remaining drying time for the clothes is the third time t3.

[0105] The third time t3 is positively correlated with the weight of the clothes after one dehydration in the clothes treatment tub 120, that is, the heavier the clothes after one dehydration, the longer the third time t3.

[0106] In one example, the third time t3 can be determined by the following relationship: t3 = a3k + b3, where a3 and b3 are set values, the value range of a3 is [28, 35], and the value range of b3 is [23, 28]. Preferably, a3 = 30 and b3 = 25. The coefficient k is equal to the weight m of the laundry after one dehydration, that is, k = m.

[0107] During the remaining drying time of the third time t3, the control valve 180 is controlled based on the control system so that the control valve 180 drains water at a third drainage rhythm until the drying process is finished.

[0108] The process of drainage in the third drainage rhythm includes:

[0109] The start-stop ratio of the control valve 180 is b31:b32, where b31 is used to characterize the opening time of the control valve 180, and the value range of the opening time is [15s, 30s]; b32 is used to characterize the closing time of the control valve 180, and the value range of the closing time is [10s, 25s].

[0110] In a specific example, the value range of b31 is [20s, 25s], and the value range of b32 is [15s, 20s].

[0111] When the parameters related to the first spin speed V1 are less than the maximum spin speed Vmax, it indicates that the clothes in the laundry drum 120 have not yet been dehydrated at the maximum spin speed Vmax, that is, the moisture content in the clothes is still relatively high, which is even more unfavorable for drying in the abnormal state of the drying duct 130. The clothes need to be dehydrated a second time. At this time, the control system autonomously controls the laundry drum 120 to perform the second dehydration.

[0112] In step S400, the control system obtains relevant information of the second dehydration of the clothes processing drum 120, that is, secondary dehydration information, and determines subsequent drying parameters of the clothes according to the secondary dehydration information.

[0113] In the above example, when it is determined that the drying duct 130 is in an abnormal state, the control system autonomously controls whether the clothing processing drum 120 needs to be dehydrated for the second time, and determines the subsequent drying parameters of the clothing based on the secondary dehydration information, thereby effectively improving the subsequent drying effect of the clothing, and improving the service life of the clothing processing equipment and the user experience.

[0114] like Figure 3 As shown, in some embodiments, when determining subsequent drying parameters for the clothes based on the secondary dehydration information, the second dehydration speed V2 of the clothes processing drum 120 can be first obtained based on the control system. Then, the drying parameters for the clothes are determined based on the second dehydration speed V2.

[0115] The drying parameters of the clothes include the remaining drying time and the drainage rhythm of the control valve 180 .

[0116] When the second spin speed V2 is greater than or equal to the maximum spin speed Vmax of the laundry processing drum 120 during dehydration, it indicates that the laundry in the laundry processing drum 120 has reached the maximum spin speed and the moisture content in the laundry has reached the minimum value. The remaining drying time of the laundry is determined to be the first time t1. The first time t1 is positively correlated with the weight of the laundry in the laundry processing drum 120 after the second dehydration. That is, the heavier the weight of the laundry after the second dehydration, the longer the first time t1.

[0117] In one example, the first time t1 can be determined by the following relationship: t1 = a1k + b1, where a1 and b1 are set values, a1 has a value range of [20, 27 s], and b1 has a value range of [10, 22]. Preferably, a1 = 25 and b1 = 20. The coefficient k is equal to the weight m of the laundry after one dehydration, that is, k = m.

[0118] During the remaining drying time of the first time t1 , the control valve 180 is controlled based on the control system so that the control valve 180 drains water at a first drainage rhythm until the drying process is finished.

[0119] The process of draining water in the first drainage rhythm includes:

[0120] The start-stop ratio of the control valve 180 is b11:b12, where b11 is used to characterize the opening time of the control valve 180, and the value range of the opening time is [12s, 28s]; b12 is used to characterize the closing time of the control valve 180, and the value range of the closing time is [12s, 24s].

[0121] In a specific example, the value range of b11 is [20s, 25s], and the value range of b12 is [15s, 20s].

[0122] When the second dehydration speed V2 is lower than the maximum dehydration speed Vmax of the clothes processing drum 120, the clothes processing drum 120 has been dehydrated twice, so the clothes can be heated directly by using the drying element 134 in the drying duct 130 in conjunction with the drying fan 133.

[0123] The control system determines the remaining drying time for the laundry in the laundry treatment drum 120 as the second time t2. The second time t23 is positively correlated with the weight of the laundry after the second spin cycle in the laundry treatment drum 120; that is, the heavier the laundry after the second spin cycle, the longer the second time t2. It should be noted that the second time t2 is greater than the third time t3. This means that the laundry requires a longer drying time than the laundry that has been spun once and at the maximum spin speed. This ensures that the laundry is thoroughly dried, avoiding incomplete or under-drying.

[0124] In one example, the second time t2 can be determined by the following relationship: t2 = a2k + b2, where a2 and b2 are set values, the value range of a2 is [36, 45], and the value range of b2 is [28, 35]. Preferably, a2 = 40 and b2 = 30. The coefficient k is equal to the weight m of the clothes after the second dehydration, that is, k = m.

[0125] During the remaining drying time of the second time t2, the control valve 180 is controlled based on the control system so that the control valve 180 drains water at a second drainage rhythm until the drying process is finished.

[0126] The process of draining water in the second drainage rhythm includes:

[0127] The start-stop ratio of the control valve 180 is b21:b22, where b21 is used to characterize the opening time of the control valve 180, and the value range of the opening time is [15s, 30s]; b22 is used to characterize the closing time of the control valve 180, and the value range of the closing time is [15s, 30s].

[0128] In a specific example, the value range of b21 is [20s, 25s], and the value range of b22 is [15s, 20s].

[0129] The opening time of the control valve 180 in the first drainage rhythm is greater than the opening time of the control valve 180 in the second drainage rhythm. Also, the closing time of the control valve 180 in the first drainage rhythm is less than the closing time of the control valve 180 in the second drainage rhythm.

[0130] In the above example, different working conditions in the clothes drying process are determined according to the correspondence between the first spin speed V1, the second spin speed V2 and the maximum spin speed Vmax. By executing different drainage rhythms based on different drying conditions, the service life of the control valve 180 or the drainage pump can be effectively extended.

[0131] 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 invoked by the processor to execute the drying control method for a laundry processing device according to the above-described embodiment.

[0132] An exemplary embodiment of the present invention further provides a clothes processing device 100. The clothes processing device 100 is controlled by the drying control method of the clothes processing device in any of the above embodiments; or has an electronic device according to the above embodiments.

[0133] In the above example, before the clothes processing drum 120 runs the drying program, the control system autonomously determines the blockage condition of the drying air duct 130 , that is, determines the dirt blockage condition in the drying air duct 130 .

[0134] Then, according to the blocking condition of the drying air duct 130 and based on the comparison between the first dehydration speed V1 and the maximum dehydration speed Vmax, it is determined whether a secondary dehydration needs to be performed.

[0135] Then, based on the secondary dehydration situation, the second dehydration speed V2 is compared with the maximum dehydration speed Vmax, and the subsequent drying parameters for the clothes are determined according to the comparison relationship at this time, thereby effectively improving the subsequent drying effect of the clothes, and can effectively improve the service life of the clothing processing device 100 and the user's usage experience, and at the same time can also ensure and improve the service life of some electrical components in the clothing processing device 100, such as the control valve 180 or the drainage pump.
