DETAILED DESCRIPTION

[0069] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0070] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0071] In an embodiment of this application, an embodiment of a method for controlling the air volume of a washing and drying device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0072] In the embodiments of this application, Figure 3 The structural diagram of the washing and drying equipment of the present application is shown. The washing and drying equipment includes a washing basin and a washing and drying machine. The washing and drying machine has a drying function, and the washing basin has a blowing function. The washing basin and the clothes dryer share a fan that provides blowing air for the washing basin and drying air for the washing and drying machine. Figure 2As shown, the fan outlet is connected to a first air duct leading to the air supply outlet of the washing machine and the dryer and a second air duct leading to the air blowing outlet of the washing tub; the first air duct is provided with a first wind shield, which is used to control the air intake of the washing machine and the dryer, and the second air duct is provided with a second wind shield, which is used to control the air intake of the washing tub.

[0073] like Figure 1 As shown, the method includes the following steps:

[0074] Step S110: In response to the operating mode of the washing tub selected by the user, controlling the second wind shield to be in a second position corresponding to the operating mode of the washing tub.

[0075] The second position is a position corresponding to the operating mode of the washing tub. The second position of the second wind shield is preset to correspond to each operating mode of the washing tub. Different operating modes of the washing tub require different air intake volumes, and therefore, the second position of the second wind shield also varies.

[0076] Specifically, in response to the working mode of the washing tub selected by the user, the second wind deflector is controlled to be in a second position corresponding to the working mode of the washing tub. Optionally, the user can select the working mode of the washing tub on the operating interface of the washing and drying equipment, and the user can also select the working mode of the washing tub on the application of the mobile terminal. Correspondingly, when the selection operation of the working mode of the washing tub is received on the operating interface of the washing and drying equipment or the application of the mobile terminal, the second wind deflector is controlled to be in the second position corresponding to the working mode in response to the working mode.

[0077] For example, Figure 4 The structure of the windshield is shown. The windshield 9 is connected to the gear 11, and the gear is connected to the motor 10. The motor 10 controls the rotation of the gear 11, thereby controlling the rotation of the windshield 9.

[0078] Step S120: Determine the current drying stage of the washing and drying machine.

[0079] The drying stage refers to the stage when the washing and drying machine is processing clothes. In the embodiment of the present application, the drying stage includes four stages: washing and dehydration, drying heating, drying determination, and drying cooling. Of course, the specific stages included in the drying stage may vary depending on the function of the washing and drying machine. For example, the drying stage may include three stages: drying heating, drying determination, and drying cooling.

[0080] Specifically, the current drying stage of the washing and drying machine is determined to prepare for subsequently determining the position of the first windshield of the washing and drying machine.

[0081] Step S130: Control the first wind shield to be in a first position corresponding to the current drying stage of the washing machine and the operating mode of the washing tub selected by the user according to the current drying stage of the washing machine and the operating mode of the washing tub.

[0082] It should be noted that the first position and the second position do not have a sequential relationship, nor do they represent specific positions. They are just for the convenience of description to avoid using the same technical terminology that may cause inconvenience in understanding.

[0083] Specifically, since the fan supplies air to the washer-dryer through the first air duct and to the washing tub through the second air duct, the air intake of the washing tub affects the air intake of the washer-dryer, and the air intake of the washing tub is related to the operating mode of the washing tub. The amount of air intake is related to the position of the windshield, and therefore, the operating mode of the washing tub affects the position of the first windshield of the washer-dryer. Therefore, the present application controls the first windshield to be in a first position corresponding to the current drying stage of the washer-dryer and the operating mode of the washing tub selected by the user. The technical solution of the present application realizes that when the washing tub and the washer-dryer need to be supplied with air at the same time, by controlling the position of the first windshield and the second windshield, the air intake of the different operating modes of the washing tub and the different drying stages of the washer-dryer are not affected, thereby improving the working efficiency of the washing and drying equipment and enhancing the user experience.

[0084] In an embodiment of the present application, a method for controlling the air volume of a washing and drying device is provided. The washing and drying device includes a washing tub and a washer-dryer, the washer-dryer having a drying function, and the washing tub having a blowing function. The washing tub and the washer-dryer share a fan for providing blowing air for the washing tub and drying air for the washer-dryer, and the fan outlet is connected to a first air duct leading to the air supply outlet of the washer-dryer and a second air duct leading to the blowing outlet of the washing tub. The first air duct is provided with a first windshield for controlling the air volume entering the washer-dryer, and the second air duct is provided with a second windshield for controlling the air volume entering the washing tub. In the technical solution of the present application, in response to a user-selected operating mode of the washing tub, the second windshield is controlled to a second position corresponding to the operating mode of the washing tub, thereby controlling the air volume entering the second air duct according to the operating mode of the washing tub. The current drying stage of the washing machine and dryer is determined, and according to the current drying stage of the washing machine and the working mode of the washing tub selected by the user, the first wind shield is controlled to be in the first position corresponding to the current drying stage of the washing machine and the working mode of the washing tub. Since the second position of the second wind shield of the washing tub will affect the air intake of the washing machine and dryer, the present application takes the drying stage of the washing machine and the working mode of the washing tub as the basis for determination, and then the first position of the first wind shield of the washing machine and dryer avoids the air intake of the washing machine and dryer being affected when the fan supplies air to the washing tub and the washing tub at the same time.

[0085] In another embodiment of the present application, controlling the first wind shield to be in a first position corresponding to the current drying stage of the washing machine and the working mode of the washing tub selected by the user according to the current drying stage of the washing machine and the working mode of the washing tub includes: adjusting the position of the first wind shield to the first position corresponding to the current working mode of the washing tub and the current drying stage of the washing machine according to a mapping relationship among the working mode of the washing tub, the drying stage of the washing machine, and the first position of the first wind shield.

[0086] The mapping relationship may be in the form of a mapping table. For example, in the mapping table, the working mode of the washing basin, the drying stage of the washing and drying machine, and the first position of the first wind shield correspond one to one. The washing basin may include multiple working modes, and the washing and drying machine may include multiple drying stages.

[0087] Specifically, a mapping relationship is pre-set between the operating mode of the wash basin, the drying stage of the washer-dryer, and the first position of the first windshield. This allows the first position of the first windshield to be determined based on the mapping relationship, the current operating mode of the wash basin, and the current drying stage of the washer-dryer. The method of this application allows for rapid determination of the first position of the first windshield, thereby accelerating the drying stage of the washer-dryer.

[0088] In another embodiment of the present application, Figure 5This is a schematic diagram of the positions of the first wind shield and the second wind shield in the embodiment of the present application. The working modes of the washing basin include washing mode, blowing mode, and clothes blowing mode; the controlling the second wind shield to be in the second position corresponding to the working mode of the washing basin includes: when the working mode of the washing basin is washing mode, controlling the second wind shield to be in position d1; when the working mode of the washing basin is blowing mode, controlling the second wind shield to be in position d2; when the working mode of the washing basin is clothes blowing mode, controlling the second wind shield to be in position d3;

the drying stages of the washing and drying machine include a washing and dehydrating stage, a drying heating stage, a drying determination stage, and a drying cooling stage; the controlling of the first wind shield to be in the first position corresponding to the current drying stage of the washing and drying machine and the working mode of the washing tub selected by the user according to the current drying stage of the washing and drying machine and the working mode of the washing tub selected by the user includes: when the working mode of the washing tub is the washing mode, the second wind shield is in position d1 and the washing and dehydrating stage, the air inlet first wind shield is in position k1;

when the working mode of the washing tub is the washing mode, the second wind shield is in the d1 position and the washing machine is in the drying and heating stage, the first air inlet wind shield is in the k4 position; when the working mode of the washing tub is the blowing mode, the second wind shield is in the d2 position and the washing machine is in the washing and dehydrating stage, the first air inlet wind shield is in the k1 position; when the working mode of the washing tub is the washing mode, the second wind shield is in the d2 position and the washing machine is in the washing and dehydrating stage, the first air inlet wind shield is in the k1 position When the washing tub is in the blowing mode, the second wind shield is in the d2 position, and the washer-dryer is in the drying and cooling stage, the first air inlet wind shield is in the k5 position; when the washing tub is in the blowing mode, the second wind shield is in the d2 position, and the washer-dryer is in the drying and drying stage, the first air inlet wind shield is in the k6 position; when the washing tub is in the blowing mode, the second wind shield is in the d2 position, and the washer-dryer is in the drying and heating stage, the first air inlet wind shield is in the k7 position; when the washing tub is in the clothes blowing mode, the second wind shield is in the d3 position, and the washer-dryer is in the washing and dehydrating stage, the first air inlet wind shield is in the k1 position;When the working mode of the washing tub is the clothes blowing mode, the second wind shield is in the d3 position, and the washer-dryer is in the drying and cooling stage, the first air inlet wind shield is in the k8 position; when the working mode of the washing tub is the clothes blowing mode, the second wind shield is in the d3 position, and the washer-dryer is in the drying and drying stage, the first air inlet wind shield is in the k9 position;

and the ventilation volume of the first wind shield at position k3 is less than the ventilation volume of the first wind shield at position k4.

[0089] It should be noted that the same ventilation volume when the first windshield is in positions k2, k5, and k8 means that the ventilation volume of the first air duct of the washer-dryer is the same. Similarly, the same ventilation volume when the first windshield is in positions k3, k6, and k9, and the same ventilation volume when the first windshield is in positions k4, k7, and k10, all have the same meaning. The embodiments of this application are merely illustrative. Depending on the washing and drying equipment, the operating mode of the washtub and the drying stage of the washer-dryer may also vary. The required air intake volume for the different operating modes of the washtub and the required air intake volume for the different drying stages of the washer-dryer are not specifically limited and can be determined based on actual conditions.

[0090] In another embodiment of the present application, after the step of controlling the first wind shield to be in the first position corresponding to the current drying stage of the washing and dryer and the working mode of the washing basin selected by the user, the step also includes: obtaining the actual pressure value of the first wind shield based on the first position of the first wind shield; and adjusting the position of the first wind shield according to the current drying stage of the washing and dryer and the actual pressure value of the first wind shield at the first position.

[0091] A pressure sensor is provided on the first windshield to measure the pressure value caused by the wind force on the first windshield. The actual pressure value of the first windshield can represent the current air flow into the first air duct, that is, the position of the first windshield affects the air flow into the first air duct.

[0092] Specifically, according to the first position of the first wind shield, the actual pressure value of the first wind shield is measured, and according to the current drying stage of the washing and dryer and the actual pressure value of the first wind shield at the first position, the position of the first wind shield is adjusted. For example, if the actual pressure value of the first wind shield does not meet the preset conditions corresponding to the current drying stage of the washing and dryer, the position of the first wind shield is adjusted so that the actual pressure value of the first wind shield meets the preset conditions corresponding to the current drying stage of the washing and dryer, thereby ensuring that the washing and dryer can proceed smoothly in the current drying stage.

[0093] In another embodiment of the present application, adjusting the position of the first wind shield according to the current drying stage of the washing machine and the actual pressure value of the first wind shield in the first position includes: determining a preset pressure threshold of the first wind shield according to the current working mode of the washing tub and the current drying stage of the washing machine and the dryer; adjusting the current position of the first wind shield according to the preset pressure threshold and the actual pressure value of the first wind shield; adjusting the current position of the first wind shield according to the preset pressure threshold and the actual pressure value of the first wind shield includes: when the actual pressure value of the first wind shield is less than or equal to the preset pressure threshold, controlling the position of the first wind shield to remain unchanged; when the actual pressure value of the first wind shield is greater than the preset pressure threshold, increasing the opening and closing angle of the first wind shield and obtaining the updated actual pressure value of the first wind shield in real time; when the updated actual pressure value is less than or equal to the preset pressure threshold, stopping increasing the opening and closing angle of the first wind shield and ending the air volume adjustment of the washing machine and dryer.

[0094] In an embodiment of the present application, a preset pressure threshold of the first wind shield is determined based on the current operating mode of the washing tub and the current drying stage of the washer-dryer. Furthermore, when the actual pressure value of the first wind shield is less than or equal to the preset pressure threshold, the position of the first wind shield is controlled to remain unchanged. When the actual pressure value of the first wind shield is greater than the preset pressure threshold, the opening and closing angle of the first wind shield is increased, thereby changing the air intake volume of the first air duct. The actual pressure value of the first wind shield is updated in real time. When the updated actual pressure value is less than or equal to the preset pressure threshold, the increase in the opening and closing angle of the first wind shield is stopped. At this point, the air intake volume of the first air duct can meet the instantaneous air volume requirement of the washer-dryer, and the air volume adjustment of the washer-dryer is terminated. This embodiment of the present application achieves air volume control of the washer-dryer by controlling the opening and closing angle of the first wind shield based on a comparison between the actual pressure value of the first wind shield and the preset pressure threshold of the current drying stage of the washer-dryer.

[0095] In another embodiment of the present application, after adjusting the position of the first wind shield according to the current drying stage of the washing machine and the actual pressure value of the first wind shield in the first position, the method further includes: determining a preset rated time according to the current working mode of the washing tub; determining a preset timeout time according to the current drying stage of the washing machine; and judging whether the washing machine has an air intake timeout fault according to the preset rated time, the preset timeout time, the preset pressure thresholds corresponding to the current working mode of the washing tub and the current drying stage of the washing machine, and the actual pressure value.

[0096] The air intake timeout fault refers to a fault reported when the air intake does not meet the preset requirements, such as the air intake volume not meeting the required volume within the preset time.

[0097] Specifically, a preset rated time is determined based on the current working mode of the washing tub, and a preset timeout time is determined based on the current drying stage of the washing machine and dryer. Based on the preset rated time, the preset timeout time, the preset pressure thresholds corresponding to the current working mode of the washing tub and the current drying stage of the washing machine and dryer, and the actual pressure value of the first wind shield, it is determined whether the washing machine and dryer have an air intake timeout fault. In an embodiment of the present application, after adjusting the position of the first wind shield, it is determined whether the washing machine and dryer have an air intake timeout fault. This avoids the problem of improper handling of clothes due to the inability to detect the air intake timeout fault in time. Optionally, a corresponding prompt message is generated for the air intake timeout fault. The prompt method can be to remind the user of the air intake timeout fault in the application of the mobile terminal, or to display the prompt message on the display interface of the washing and drying device, or to remind the user in the form of sound effects, indicator lights, etc. on the washing and drying device.

[0098] In another embodiment of the present application, determining whether an air intake timeout fault has occurred in the washer-dryer based on a preset rated duration, a preset timeout duration, preset pressure thresholds corresponding to the current operating mode of the washing tub and the current drying stage of the washing tub, and the actual pressure value, includes: starting timing and continuously acquiring updated actual pressure values ​​while controlling the position of the first air shield to remain unchanged or stopping increasing the opening and closing angle of the first air shield; and when the timed duration reaches a total duration, if the sum of the durations during which the actual pressure values ​​are greater than the preset pressure thresholds is greater than the instantaneous total pressure duration, or the total pressure value of the washing tub is greater than a preset total pressure value, then an air intake timeout fault has occurred in the washing tub, wherein the total duration is the sum of the preset rated duration and the timeout duration, the instantaneous total pressure duration is determined based on the current operating mode of the washing tub and the current drying stage of the washing tub, the preset total pressure value is determined based on the current operating mode of the washing tub and the current drying stage of the washing tub, and the total pressure value is equal to the sum of the actual pressure values.

[0099] Specifically, when the position of the first windshield is controlled to remain unchanged or the increase in the opening and closing angle of the first windshield is stopped, that is, when the air volume adjustment of the washing and drying machine is ended, timing is started and the updated first actual pressure value is continuously obtained. When the timing time reaches the total time, it is determined whether the sum of the time periods when the actual pressure value is greater than the preset pressure threshold is less than or equal to the instantaneous total pressure time, and whether the total pressure value of the washing and drying machine is less than or equal to the total pressure value requirement. If both conditions are met, the washing and drying machine does not have an air intake timeout fault. If any one of the conditions is not met, it indicates that the washing and drying machine has an air intake timeout fault. The method of the present application realizes the judgment of the air intake timeout fault of the washing and drying machine, which facilitates the user to timely understand the status of the washing and drying machine.

[0100] In another embodiment of the present application, a method for controlling the air volume of a washing and drying device is provided, such as Figure 6 As shown, the air volume control method of the washing and drying equipment in the embodiment of the present application is a preferred embodiment of the above-mentioned embodiment, wherein the positions of the first windshield and the second windshield in the embodiment of the present application can refer to Figure 5 The same or similar technical terms as those in the above embodiments will not be repeated.

[0101] like Figure 6 As shown, the embodiment of the present application includes the following steps:

[0102] First, start the washing and drying equipment, and secondly determine the mode of the washing tub.

[0103] In this application, the modes of the washing tub include, but are not limited to, washing mode, air-blowing mode, and clothes-blowing mode. In washing mode, the air-blowing function is not required, and the clothes-blowing mode requires more air than the air-blowing mode. The washing tub mode can be obtained by triggering the washing tub mode.

[0104] Afterwards, the stage of the washing machine and dryer is determined according to the mode corresponding to the washing tub.

[0105] Among them, the washing and drying machine is divided into four stages: washing and dehydration, drying heating, drying judgment and drying cooling stages. The air intake volume required in different drying stages is different. The air intake volume required in the drying heating stage is more than that in the drying judgment, and the air intake volume required in the drying judgment is more than that in the drying cooling stage.

[0106] Specifically, the corresponding stage may be determined according to the preset stage duration and stage triggering operation of the washing and drying machine.

[0107] Figure 6 The air volume control of each mode of the washing tub and each stage of the washing and drying machine is clearly described:

[0108] When the washing tub is in washing mode, the second wind shield is in position d1, and the drying stage of the washing and drying machine is judged to be the washing and dehydration stage, the first wind shield is in position k1, the first air duct of the washing and drying machine is in the closed state, and the fan does not need to be turned on. At this time, the washing and drying machine does not need to judge the air intake timeout fault logic, and the air intake timeout fault is not calculated.

[0109] When the washing tub is in washing mode, the second air shield is in position d1, and the washer-dryer is determined to be in the drying and cooling phase, the first air shield is in position k2. The pressure sensor monitors the pressure in real time. If the pressure value of the first air shield of the washer-dryer is less than or equal to p1, the washer-dryer air inlet timeout fault logic switches to control 2, i.e., determining the air inlet timeout as T1+t1. T1 is the preset rated duration corresponding to the washing tub in washing mode and the washer-dryer in the drying and cooling phase, and t1 is the preset timeout duration corresponding to the washing tub in washing mode and the washer-dryer in the drying and cooling phase. It should be understood that the following methods for determining the air inlet timeouts T2+t2, T3+t3, etc. are similar to the aforementioned method for determining T1+t1, and their determination methods will not be further described. p1 is the preset pressure threshold corresponding to the washing tub in washing mode and the washer-dryer in the drying and cooling phase. The subsequent methods for obtaining p2, p3, etc. are similar to the method for obtaining p1, and will not be further described. y1 is the preset instantaneous total pressure duration, set according to the washing mode of the washing tub and the washing and dehydration phases of the washer-dryer. P1 is the preset total pressure value, set according to the washing mode of the washing tub and the washing and dehydration phases of the washer-dryer. In the embodiment of the present application, a preset instantaneous pressure threshold, a preset timeout duration, a preset rated duration, a preset total pressure value, and a preset instantaneous total pressure duration are set, respectively, according to the operating mode of the washing tub and the drying phase of the washer-dryer. The air intake timeout duration is differentiated based on the state of the second wind deflector. That is, the time required for air intake in the washer-dryer varies depending on the operating mode of the washing tub. T1<T2<T3. When the second wind shield is in a certain position, the timeout time is adjusted according to the different drying stages of the washing and drying machine: t3>t2>t1, t6>t5>t4, t9>t8>t7. The total pressure value judgment condition is P1>P2>P3, P4>P5>P6, P7>P8>P9. The cumulative time judgment condition is y1<y2<y3, y4<y5<y6, y7<y8<y9.

[0110] When the pressure value of the first windshield is greater than p1, the first windshield tends to rotate horizontally, increasing the angle with the vertical direction, and monitors the pressure value in real time. When the pressure value is less than or equal to p1, the timing starts, and when the timing reaches T1+t1, the total pressure value within T1+t1 is recorded, that is, the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than P1, or the cumulative time that the instantaneous pressure value is greater than p1 is greater than y1, it indicates an air intake timeout fault, and the entire machine reports an air intake timeout fault. If the total pressure value is less than or equal to P1, and the cumulative time that the instantaneous pressure value is greater than p1 is less than or equal to y1, then the washing machine has not experienced an air intake timeout fault, and the first windshield maintains its current position.

[0111] When the washing tub is in washing mode, the second air shield is in position d1, and the washer-dryer is determined to be in the drying phase, the first air shield is in position k3. The pressure sensor monitors the pressure in real time. If the pressure value of the first air shield is less than or equal to p2, the washer-dryer's air inlet timeout fault logic switches to control three, determining the air inlet timeout as T2 + t2. If the pressure value of the first air shield is greater than p2, the first air shield rotates laterally, increasing its angle with the vertical direction, and the pressure value is monitored in real time. If the pressure value is less than or equal to p2, a timer is started. When the timer reaches T2 + t2, the total pressure value within T2 + t2 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than P2, or if the cumulative time for which the instantaneous pressure value is greater than p2 is greater than y2, an air inlet timeout fault has occurred, and the entire machine will report an air inlet timeout fault. If the total pressure value is less than or equal to P2, and the cumulative time that the instantaneous pressure value is greater than p2 is less than or equal to y2, the washing and drying machine does not have an air intake timeout fault, and the first windshield maintains its current position.

[0112] When the washing tub is in washing mode, the second air shield is in position d1, and the washer-dryer is determined to be in the drying and heating phase, the first air shield is in position k4. The pressure sensor monitors the pressure in real time. If the pressure value of the first air shield is less than or equal to p3, the washer-dryer's air inlet timeout fault logic switches to control 4, determining the air inlet timeout as T3 + t3. If the pressure value of the first air shield is greater than p3, the first air shield rotates laterally, increasing its angle with the vertical direction, and the pressure value is monitored in real time. If the pressure value is less than or equal to p3, a timer is started. When the timer reaches T3 + t3, the total pressure value within T3 + t3 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than P3, or if the cumulative time for which the instantaneous pressure value is greater than p3 is greater than y3, an air inlet timeout fault has occurred, and the entire machine will report an air inlet timeout fault. If the total pressure value is less than or equal to P3, and the cumulative time that the instantaneous pressure value is greater than p3 is less than or equal to y3, the washing and drying machine does not have an air intake timeout fault, and the first windshield maintains its current position.

[0113] When the washing tub is in blowing mode, the second wind shield is in position d2, and the drying stage of the washing and drying machine is judged to be the washing and dehydration stage, the first wind shield is in position k1, the first air duct of the washing and drying machine is in the closed state, and the fan does not need to be turned on. At this time, the washing and drying machine does not need to judge the air intake timeout fault logic, and the air intake timeout fault is not calculated.

[0114] When the washing tub is in blower mode, the second air shield is in position d2, and the washer-dryer is determined to be in the drying and cooling phase, the first air shield is in position k5. The pressure sensor monitors the pressure in real time. If the pressure on the first air shield is less than or equal to p5, the washer-dryer's air inlet timeout fault logic switches to control five, determining the air inlet timeout as T5 + t5. If the pressure on the first air shield is greater than p5, the first air shield rotates laterally, increasing its angle with the vertical direction, and the pressure is monitored in real time. If the pressure is less than or equal to p5, a timer begins. When the timer reaches T5 + t5, the total pressure value within T5 + t5 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than p5, or if the cumulative time for which the instantaneous pressure value is greater than p5 is greater than y5, an air inlet timeout fault has occurred, and the entire machine reports an air inlet timeout fault. If the total pressure value is less than or equal to P5, and the cumulative time that the instantaneous pressure value is greater than p5 is less than or equal to y5, the washing and drying machine does not have an air intake timeout fault, and the first windshield maintains the current position.

[0115] When the washing tub is in blower mode, the second air shield is in position d2, and the washer-dryer is determined to be in the drying phase, the first air shield is in position k6. The pressure sensor monitors the pressure in real time. If the pressure value of the first air shield is less than or equal to p6, the washer-dryer's air inlet timeout fault logic switches to control six, determining the air inlet timeout as T6 + t6. If the pressure value of the first air shield is greater than p6, the first air shield rotates laterally, increasing its angle with the vertical direction, and the pressure value is monitored in real time. If the pressure value is less than or equal to p6, a timer is started. When the timer reaches T6 + t6, the total pressure value within T6 + t6 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than p6, or if the cumulative time for which the instantaneous pressure value is greater than p6 is greater than y6, an air inlet timeout fault has occurred, and the entire machine reports an air inlet timeout fault. If the total pressure value is less than or equal to P6, and the cumulative time that the instantaneous pressure value is greater than p6 is less than or equal to y6, the washing and drying machine does not have an air intake timeout fault, and the first wind deflector maintains its current position.

[0116] When the washing tub is in blower mode, the second air shield is in position d2, and the washer-dryer is determined to be in the drying and heating phase, the first air shield is in position k7. The pressure sensor monitors the pressure in real time. If the pressure value of the first air shield is less than or equal to p7, the washer-dryer's air inlet timeout fault logic switches to control seven, determining the air inlet timeout as T7 + t7. If the pressure value of the first air shield is greater than p7, the first air shield rotates laterally, increasing its angle with the vertical direction, and the pressure value is monitored in real time. If the pressure value is less than or equal to p7, a timer is started. When the timer reaches T7 + t7, the total pressure value within T7 + t7 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than p7, or if the cumulative time for which the instantaneous pressure value is greater than p7 is greater than y7, an air inlet timeout fault has occurred, and the entire machine will report an air inlet timeout fault. If the total pressure value is less than or equal to P7, and the cumulative time that the instantaneous pressure value is greater than p7 is less than or equal to y7, the washing and drying machine does not have an air intake timeout fault, and the first wind deflector maintains its current position.

[0117] When the washing tub is in clothes blowing mode, the second wind deflector is in position d3, and the drying stage of the washing and drying machine is judged to be the washing and dehydration stage, the first wind deflector is in position k1, the first air duct of the washing and drying machine is in the closed state, and the fan does not need to be turned on. At this time, the washing and drying machine does not need to judge the air intake timeout fault logic, and the air intake timeout fault is not calculated.

[0118] When the washing tub is in drying mode, the second air shield is in position d3, and the washer-dryer is determined to be in the drying and cooling phase, the first air shield is in position k8. The pressure sensor monitors the pressure in real time. If the pressure value of the first air shield is less than or equal to p8, the washer-dryer's air inlet timeout fault logic switches to control eight, determining the air inlet timeout as T8 + t8. If the pressure value of the first air shield is greater than p8, the first air shield rotates laterally, increasing its angle with the vertical direction, and the pressure value is monitored in real time. If the pressure value is less than or equal to p8, a timer is started. When the timer reaches T8 + t8, the total pressure value within T8 + t8 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than p8, or if the cumulative time for which the instantaneous pressure value is greater than p8 is greater than y8, an air inlet timeout fault has occurred, and the entire machine will report an air inlet timeout fault. If the total pressure value is less than or equal to P8, and the cumulative time that the instantaneous pressure value is greater than p8 is less than or equal to y8, the washing and drying machine does not have an air intake timeout fault, and the first wind deflector maintains its current position.

[0119] When the washing tub is in the clothes-blowing mode, the second air shield is in position d3, and the washer-dryer is determined to be in the drying phase, the first air shield is in position k9. The pressure sensor monitors the pressure value in real time. If the pressure value of the first air shield of the washer-dryer is less than or equal to p9, the washer-dryer's air inlet timeout fault logic switches to control nine, determining the air inlet timeout as T9 + t9. If the pressure value of the first air shield is greater than p9, the first air shield rotates laterally, increasing the angle with the vertical direction, and the pressure value is monitored in real time. If the pressure value is less than or equal to p9, a timer is started. When the timer reaches T9 + t9, the total pressure value within T9 + t9 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than p9, or the cumulative time that the instantaneous pressure value is greater than p9 is greater than y9, an air inlet timeout fault has occurred, and the entire machine reports an air inlet timeout fault. If the total pressure value is less than or equal to P9, and the cumulative time that the instantaneous pressure value is greater than p9 is less than or equal to y9, the washing and drying machine does not have an air intake timeout fault, and the first wind deflector maintains its current position.

[0120] When the washing tub is in drying mode, the second air deflector is in position d3, and the washer-dryer is determined to be in the drying and heating phase, the first air deflector is in position k10. The pressure sensor monitors the pressure in real time. If the pressure on the first air deflector is less than or equal to p10, the washer-dryer's air inlet timeout fault logic switches to control 10, determining the air inlet timeout as T10 + t10. If the pressure on the first air deflector is greater than p10, the first air deflector rotates laterally, increasing its angle with the vertical direction, and the pressure is monitored in real time. If the pressure is less than or equal to p10, a timer begins. When the timer reaches T10 + t10, the total pressure value within T10 + t10 is recorded. This is the sum of each instantaneous pressure value monitored in real time by the pressure sensor. If the total pressure value is greater than p10, or if the cumulative time for which the instantaneous pressure value is greater than p10 is greater than y10, an air inlet timeout fault has occurred, and the entire machine reports an air inlet timeout fault. If the total pressure value is less than or equal to P10, and the cumulative time that the instantaneous pressure value is greater than p10 is less than or equal to y10, the washing and drying machine does not have an air intake timeout fault, and the first windshield maintains the current position.
