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

[0064] 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.

[0065] like Figure 1As shown, an exemplary embodiment of the present invention provides a clothes processing device 100. The clothes processing device may include but is not limited to a washing machine, and 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 a drying or washing and care function, and 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 clothes processing device 100 includes a body 110 and a clothes processing drum 120 disposed inside the body 110. A drying air duct 130 is disposed on the body 110, and an air outlet 131 of the drying air duct 130 is communicated with the interior of the clothes processing drum 120. The drying air duct 130 has a plurality of air inlets 132, and the plurality of air inlets 132 are also communicated with the interior of the clothes 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, that is, 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 fin tube, and the like.

[0069] When the washer-dryer is powered on and runs the drying program, the drying element 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 in the direction of the arrow in the figure, the drying airflow flows along the drying duct 130, and then enters the interior of the clothing treatment drum 120 through the air inlet 132 to dry the clothes in the clothing treatment drum 120, and the free water and bound water in the clothes form hot and humid air. Finally, the humid air enters the drying duct 130 through multiple air outlets 131, and the water molecules of the humid air are removed through condensation. The treated air is heated again by the drying element 134 and re-enters the clothing treatment drum 120 to continue drying the clothes, and this is repeated to achieve drying of the clothes.

[0070] The body 110 is also provided with a condenser 140 and a condenser valve 150. The condenser 140 may have a plurality of water inlets 141. One of the water inlets 141 extends into the laundry treatment tub 120 and is directly arranged opposite to the guide ribs 121 on the inner wall of the laundry treatment tub 120. Condensed water entering through the water inlet 141 may directly flow onto the guide ribs 121, so that the condensed water enters the laundry treatment tub 120 in a dispersed form. The remaining water inlets 141 may be arranged in the drying air duct 130, so that the water molecules in the humid air are condensed by using the water inlets 141 arranged at the positions, thereby removing the water molecules in 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 rate or flow velocity of the condensation water in the condensation tube 140, thereby accurately controlling the flow rate or flow velocity of the condensation water entering the clothing processing drum 120.

[0072] A drain port 122 is provided at the bottom of the laundry treatment tub 120, and a control valve 180 or a drain pump is provided on a drain pipe connected to the drain port 122. When the laundry treatment tub 120 runs a drying program, adaptive drainage can be performed by opening or closing the control valve 180 or the drain pump.

[0073] During the clothes drying process, it is necessary to monitor the temperature at relevant positions in the clothes processing drum 120. For example, a first temperature detection member 123 is provided at the position of the drain port 122 of the clothes processing drum 120, a second temperature detection member 124 is provided at a position close to the drying fan 133, and a third temperature detection member 125 is provided at a position close to the air inlet 132.

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

[0075] It should be noted that the first temperature detection element 123 is used to obtain the drainage temperature of the laundry treatment drum 120. The second temperature detection element 124 is used to detect the return air temperature of the return air flow returning from the drying air duct 130. And the third temperature detection element 125 is used to obtain the drying air flow temperature of the drying air flow entering the laundry treatment 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, and the outlet end 161 of the flushing pipe 160 is connected to the interior of the drying air duct 130. It should be noted that the flushing pipe 160 is used to flush the blocked position in the drying air duct 130 or the position where hair debris is easily accumulated to ensure the patency of the drying air 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 laundry processing drum, determining whether the drying air 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 laundry processing tub during dehydration, the laundry 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, it is first determined based on the control system of the clothes processing device 100 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, the circulation of the drying airflow in the drying duct 130 will be affected, 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 heating stage, wherein the inlet temperature of the inlet of the laundry processing drum 120 (i.e., the air outlet 131 of the drying air duct 130) is obtained based on the third temperature detection element 125, and the outlet temperature of the outlet of the laundry processing drum 120 (i.e., the air inlet 132 of the drying air duct 130) is obtained based on the second temperature detection element 124.

[0087] When the inlet temperature is outside the first threshold range and the outlet temperature is outside the second threshold range, it is determined that the drying temperature rise stage is 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 execution time t of the drying and heating stage is determined by the control system, or the temperature difference ΔT of the laundry treatment drum 120 is determined, and the temperature difference ΔT is used to characterize the inlet temperature T 进 With outlet temperature T 出 The difference between 进 -T 出 ).

[0089] Finally, when one of the following conditions is satisfied, 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 air duct 130 is in an abnormal state. The preset time range is [50min, 60min].

[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 is continued, and the drying time of the clothes is determined to be the fourth time t4. The fourth time t4 is positively correlated with the weight of the clothes after the clothes treatment drum 120 is dehydrated once, that is, the heavier the weight of the clothes after 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, a4 has a value range of [20, 27s], b4 has a value range of [10, 22], preferably, a4 = 25, b4 = 20. The coefficient k is equal to the weight m of the clothes 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 so that the control valve 180 drains water at a fourth drainage rhythm until the drying process ends.

[0096] Among them, the process of drainage in the fourth drainage rhythm includes:

[0097] The start-stop ratio of the control valve 180 is b41:b42, wherein 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, when it is determined that the drying air duct 130 is in an abnormal state, the flushing valve 170 can be opened first, and the drying fan 133 can be turned on at the same time, so as to use the water in the flushing pipe 160 and the wind of the drying fan 133 to blow and flush the drying air duct 130 for a predetermined time to remove some of the blocked materials in the drying air duct 130. The preset time can be 20 seconds.

[0100] It should be noted that in this example, the flushing valve 170 is controlled to be opened 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 in each washing program, and the drying duct 130 is flushed for about 10 seconds.

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

[0102] The first dehydration speed V1 before the laundry treatment drum 120 runs the drying program is acquired based on the control system. 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 relevant parameters of the first dehydration speed V1 are greater than or equal to the maximum dehydration speed Vmax, it indicates that the clothes in the laundry treatment drum 120 have been dehydrated at the maximum speed, and the moisture content in the clothes has reached the minimum value, and there is no need to dehydrate the clothes for a second time. At this time, the remaining drying time of the clothes is determined to be the third time t3 based on the control system.

[0105] The third time t3 is positively correlated with the weight of the clothes after one dehydration of the clothes treatment tub 120, that is, the heavier the weight of the clothes after one dehydration, the longer the third time t3. The third time t3 is greater than the fourth time t4.

[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, a3 has a value range of [28, 35], b3 has a value range of [23, 28], preferably, a3 = 30, b3 = 25. The coefficient k is equal to the weight m of the clothes 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 ends.

[0108] Among them, the process of drainage in the third drainage rhythm includes:

[0109] The start-stop ratio of the control valve 180 is b31:b32, wherein 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 relevant parameters of the first dehydration speed V1 are less than the maximum dehydration speed Vmax, it indicates that the clothes in the clothes processing drum 120 have not been dehydrated at the maximum dehydration speed Vmax, that is, the moisture content in the clothes is still relatively high, which is more unfavorable for drying when the drying duct 130 is in an abnormal state, and the clothes need to be dehydrated for the second time. At this time, the control system autonomously controls the clothes processing 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, the 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, in the process of determining subsequent drying parameters of the clothes according to the secondary dehydration information, the second dehydration speed V2 of the clothes treatment drum 120 can be first obtained based on the control system. Then, the drying parameters of the clothes are determined according to the second dehydration speed V2.

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

[0116] When the second dehydration speed V2 is greater than or equal to the maximum dehydration speed Vmax when the clothes treatment drum 120 is dehydrated, it indicates that the clothes in the clothes treatment drum 120 have been dehydrated at the maximum speed, and the moisture content in the clothes has reached the minimum value, and the remaining drying time of the clothes is determined to be the first time t1. The first time t1 is positively correlated with the weight of the clothes after the second dehydration in the clothes treatment drum 120, that is, the heavier the weight of the clothes 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, 27s], b1 has a value range of [10, 22], preferably, a1 = 25, b1 = 20. The coefficient k is equal to the weight m of the clothes 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 ends.

[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, wherein 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 less than the maximum dehydration speed Vmax of the clothes processing drum 120, since the clothes processing drum 120 has been dehydrated twice, the clothes can be directly heated by the drying element 134 in the drying air duct 130 in cooperation with the drying fan 133.

[0123] Based on the control system, the remaining drying time of the clothes in the clothes treatment drum 120 at this time is determined to be the second time t2. The second time t23 is positively correlated with the weight of the clothes after the clothes treatment drum 120 is dehydrated twice, that is, the heavier the weight of the clothes after the second dehydration, the longer the second time t2. It should be noted that the second time t2 is greater than the third time t3, that is, the drying time required for the clothes at this time is longer than the drying time required for the clothes that have been dehydrated once and have executed the maximum dehydration speed, so that the clothes can be completely dried, thereby avoiding the situation of not being dried or not being dried thoroughly.

[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, a2 has a value range of [36, 45], b2 has a value range of [28, 35], preferably, a2 = 40, 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 program 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, wherein 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, 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 and execute the drying control method of the clothes processing device in the above embodiment.

[0132] An exemplary embodiment of the present invention further provides a clothes processing device 100. The clothes processing device 100 is controlled by using the drying control method of the clothes processing device in any of the above embodiments; or, it is an electronic device having 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 and 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 relationship 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 experience, and at the same time, it 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.
