Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings.

The block diagrams depicted in the figures are merely functional entities and do not necessarily correspond to physically separate entities. That is, the functional entities may be implemented in software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The flow diagrams depicted in the figures are exemplary only, and do not necessarily include all of the elements and operations/steps, nor must they be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the order of actual execution may be changed according to actual situations.
When the roller and the circulating fan are controlled by the same driving motor, in order to prevent clothes from winding, in the related art, the driving motor is configured to rotate bidirectionally, and the forward-reverse rotation time ratio of the driving motor is a fixed value in the whole operation process of the drying program. The applicant found that if the reverse rotation time is short (for example, the forward and reverse rotation time ratio is 60:1), the agglomerated clothes cannot be opened due to the short reverse rotation time, and the clothes still can be entangled, so that the clothes are dried unevenly; if the configuration reverse rotation time is long (for example, the forward and reverse rotation time ratio is 1:1), the output air quantity of the circulating fan can be obviously reduced when the driving motor rotates reversely, the air quantity of hot air entering the roller is small, the air fluidity in the roller is poor, the heat exchange effect is poor, and the clothes can not be dried uniformly. For the clothes drying equipment configured with the heat pump system for carrying out heat exchange on the air outlet of the roller, as the air quantity of the hot air entering the roller is small, the vapor in the clothes cannot be evaporated into gas, and the vapor enters the compressor of the heat pump system to produce liquid impact on the compressor, so that the compressor works abnormally, and the reliability problem of the heat pump system can be caused, and meanwhile, the clothes are not dried.
Referring to fig. 1, fig. 1 shows a flow chart of a clothes drying method in the prior art, as shown in fig. 1, in the running process of the whole drying program, the forward and reverse rotation speed ratio of a driving motor is fixed to be R1 to R2, the forward and reverse rotation time ratio is fixed to be t1 to t2, and no matter whether the forward and reverse rotation time ratio t1 to t2 is set to be larger or smaller, the problem of uneven clothes drying exists. In the process of running the drying program, detecting the humidity of the clothes in the drum, judging that the clothes are dried when the humidity value of the clothes is smaller than the humidity value h1, ending the drying program, wherein misjudgment easily occurs in the drying judgment logic, particularly in the case of winding of the clothes, the humidity sensor only detects the surface humidity of the clothes, but the inside of the clothes cannot be detected, so that the clothes are misjudged to be dried under the condition of not drying the clothes, and the problem of uneven drying of the clothes is also caused.
Therefore, the application provides a clothes drying method and a related device for improving clothes drying uniformity.
The clothes drying method and the related device provided by the application are described in detail below with reference to the specific embodiments.
Fig. 2 is a schematic view showing a partial constitution of a clothes drying apparatus according to an embodiment of the present application; fig. 3 illustrates a schematic view of a wind circulation-related structure of a laundry drying apparatus according to an embodiment of the present application.
As shown in fig. 2 and 3, the laundry drying apparatus includes a cabinet 101, a front panel 102, a door 103, a circulation duct 104, a circulation fan 105, a drum 106, a driving motor 107, a heat pump system, and a controller (not shown).
Wherein, the housing 101 is formed therein with a housing space for accommodating the circulating air duct 104, the drum 106, the driving motor 107, the heat pump system, the controller and the like.
The front panel 102 is disposed at the front side of the cabinet 101, and a laundry inlet (not shown) is provided on the front panel 102, and communicates with the drum 106. When the laundry loading opening is opened, a user may load laundry to be dried into the drum 106 via the laundry loading opening, or take out the dried laundry from the drum 106.
The door body 103 is provided at one side of the laundry putting opening and hinged with the front panel 102, and the laundry putting opening is opened or closed by rotating the door body 103.
The drum 106 is rotatably provided in the cabinet 101, and when laundry is to be dried, the drum 106 is driven to rotate, so that the laundry is sufficiently contacted with hot air introduced into the drum 106 by the drum 106, thereby achieving rapid drying of the laundry.
The circulation air duct 104 has an air inlet and an air outlet, the air outlet of the circulation air duct 104 is communicated with the air inlet of the roller 106, so that hot air in the circulation air duct 104 can enter the roller 106, and the air inlet of the circulation air duct 104 is communicated with the air outlet of the heat pump system.
The circulating fan 105 is arranged in the circulating air duct 104, and the circulating fan 105 can drive dry hot air in the circulating air duct 104 to enter the roller 106 through an air outlet of the circulating air duct 104, and simultaneously drive air in the roller 106 to flow, so that air after absorbing water of clothes is discharged out of the roller 106, the air discharged out of the roller 106 enters the heat pump system through an air inlet of the heat pump system to exchange heat, and hot air is formed and then flows to the air inlet of the circulating air duct 104 through an air outlet of the heat pump system, so that the hot air returns to the circulating air duct 104.
The output shaft of the driving motor 107 is connected with the roller 106 and the circulating fan 105, and the driving motor 107 is used for driving the roller 106 and the circulating fan 105 to rotate. The rotation direction and rotation speed of the driving motor 107 are adjustable, so that the rotation direction and rotation speed of the drum 106 and the circulation fan 105 are adjusted, when the driving motor 107 rotates forward (e.g., rotates clockwise), the drum 106 and the circulation fan 105 both rotate forward, and when the driving motor 107 rotates backward (e.g., rotates counterclockwise), the drum 106 and the circulation fan 105 both rotate backward.
The heat pump system comprises an evaporator 108, a condenser 109, a compressor 110 and a throttling device 111, wherein the evaporator 108, the compressor 110, the condenser 109 and the throttling device 111 are connected through pipelines which provide a passage for the flow of heat exchanger (refrigerant) in the heat pump system. When the compressor 110 is operated, the heat exchange agent is fed into the condenser 109 to perform exothermic condensation, then enters the evaporator 108 through the throttling device 111 to perform endothermic evaporation, and then returns to the compressor 110; the air discharged from the drum 106 is cooled by the evaporator 108 and then flows to the condenser 109, and the heat discharged from the condenser 109 can heat the flowing air, so that hot air is formed, and the formed hot air enters the circulating air duct 104.
The controller is used to control the operation of the various components of the laundry drying appliance, such as the drive motor 107, the circulation blower 105, the heat pump system, etc.
It should be noted that, in some embodiments, other devices that can heat air may be used instead of the heat pump system to generate hot air, for example, an electric heating device, etc.
Fig. 4 shows a flowchart of a laundry drying method according to an embodiment of the present application, which may be performed by the laundry drying appliance, in particular by a controller of the laundry drying appliance. Referring to fig. 4, the laundry drying method at least includes steps S410 to S430, and is described in detail as follows:
in step S410, a laundry drying parameter is obtained, and it is determined whether the laundry drying parameter meets a preset condition. If the clothes drying parameters meet the preset conditions, the step S420a is carried out; if the laundry drying parameters do not meet the preset conditions, step S420b is performed.
Wherein, when the clothes drying parameter accords with the preset condition, the humidity of the clothes in the roller is larger than the humidity of the clothes in the roller when the clothes drying parameter does not accord with the preset condition, namely, when the clothes drying parameter accords with the preset condition, the clothes in the roller are wet, and when the clothes drying parameter does not accord with the preset condition, the clothes in the roller are dry.
The clothes drying parameter may be at least one of a drying program running time, an exhaust temperature, a return air temperature and a clothes humidity value, and specifically may be any one of a drying program running time, an exhaust temperature, a return air temperature and a clothes humidity value, or any two of them, or any three of them, or all of them.
The longer the running time of the drying program, i.e. the longer the drying time of the clothes in the drum, more water vapor in the clothes can be taken away, and the humidity of the clothes in the drum becomes smaller, so the running time of the drying program can be used as a judging parameter of the humidity of the clothes.
The return air temperature is the air outlet temperature of the roller. When the humidity of clothes in the roller is high, the air return temperature is low due to the fact that more water vapor in the roller is mixed with hot air; when the humidity of the clothes in the drum is small, the air return temperature becomes high because the water vapor mixed with the hot air in the drum becomes small, so the air return temperature can be used as a judging parameter of the humidity of the clothes.
The exhaust temperature is the heat exchanger temperature at the outlet of the heat pump system, i.e. the heat exchanger temperature at the outlet of the compressor. When the humidity of clothes in the roller is high, the temperature of return air is low due to the fact that more water vapor in the roller is mixed with hot air, so that more heat is taken away when the return air exchanges heat with the heat pump system, and the temperature of a heat exchanger is reduced; when the humidity of clothes in the roller is smaller, as the water vapor mixed with hot air in the roller is reduced, the return air temperature is increased, so that less heat is taken away when the return air exchanges heat with the heat pump system, and the temperature of the heat exchanger is increased, therefore, the exhaust temperature can be used as a judging parameter of the humidity of the clothes.
It should be noted that, in some embodiments, the temperature of the hot air entering the circulation duct may also be directly measured as the exhaust temperature.

As shown in fig. 5, in one embodiment of the present application, step S410 includes steps S510 to S530, which are described in detail below:
in step S510, four judgment parameters of the drying program running time T, the exhaust temperature T1, the return air temperature T2 and the laundry humidity value h are obtained.
In step S520, it is determined whether the operation time T of the drying program is less than or equal to the preset operation time T0 or the exhaust temperature T1 is less than or equal to the preset temperature T10 or the return air temperature T2 is less than or equal to the preset temperature T20 or the laundry humidity value h is more than or equal to the preset humidity value h0, if yes (i.e. one or more than one determination parameters are satisfied), step S530a is performed; otherwise (i.e., none of the judgment parameters is satisfied), the process proceeds to step S530b.
In step S530a, it is determined that the laundry drying parameter meets the preset condition.
In step S530b, it is determined that the laundry drying parameter does not meet the preset condition.
Of course, the flowchart shown in fig. 5 is only one embodiment of the step S410 of the present application, and in other embodiments, the step S410 is not limited to the steps shown in fig. 5.
In step S420a, the driving motor is controlled to operate in a first mode.
In step S420b, the driving motor is controlled to operate in the second mode. Then, the process advances to step S430.
The forward and reverse rotation time ratio of the driving motor in the second mode is smaller than that of the driving motor in the first mode, namely, the reverse rotation time of the driving motor in the second mode is longer, and the reverse rotation time of the driving motor in the first mode is shorter.
The clothes drying parameters meet preset conditions, namely that the clothes in the roller are wet, more hot air is required to enter the roller to ensure heat exchange in the drying process, so that the driving motor is controlled to operate in a first mode, namely the inversion time of the driving motor is shorter, and the heat exchange in the drying process is ensured; if the clothes drying parameters do not meet the preset conditions, the clothes in the roller are dry, and the requirement for hot air quantity is reduced at the moment, so that the driving motor is controlled to operate in a second mode, namely the inversion time of the driving motor is longer, the inversion time of the roller is prolonged, the entangled clothes can be fully opened, and the clothes drying uniformity is improved. That is, by controlling the driving motor to operate different modes in stages, the heat exchange effect in the drying process can be well considered, the clothes are prevented from being entangled, and the drying uniformity of the clothes is improved.
Illustratively, in the first mode, the forward/reverse rotation time ratio of the driving motor is 5 min/30 s; in the second mode, the forward/reverse rotation time ratio of the driving motor is 4 min/1 min.
In this application an embodiment, driving motor's reversal speed is all greater than positive rotational speed under first mode and second mode, driving motor under reverse rotation, and the output amount of wind of driving the fan can obviously decline, consequently increases driving motor's reversal speed to the output amount of wind when increasing driving motor reversal makes more hot-blast in the circulation wind channel can get into the cylinder and participate in the heat exchange, thereby takes away the steam in the clothing, is favorable to the clothing stoving even, and heat pump system's operation is also more reliable.
In one embodiment of the present application, the reverse speed of the drive motor in the second mode is less than the reverse speed of the drive motor in the first mode. When the clothes in the roller are wet, the reversing speed of the driving motor is set to be high, the output air quantity when the driving motor reverses is increased, and when the clothes in the roller are dry, the reversing speed of the driving motor is properly reduced, so that the energy consumption of the driving motor can be saved, the electric energy is saved, and meanwhile, the problem of box vibration caused by high rotating speed of the driving motor is solved.
Illustratively, in the first mode, the forward speed of the drive motor is 2500rpm and the reverse speed is 2800rpm; in the second mode, the forward rotation speed of the driving motor is 2500rpm, and the reverse rotation speed is 2700rpm.
Illustratively, in the first mode, the forward/reverse rotation time ratio of the drive motor is 5 min/30 s, the forward rotation speed of the drive motor is 2500rpm, and the reverse rotation speed is 2800rpm; in the second mode, the forward/reverse rotation time ratio of the driving motor is 4 min/1 min, the forward rotation speed of the driving motor is 2500rpm, and the reverse rotation speed is 2700rpm.
In one embodiment of the present application, the forward rotation speed and the reverse rotation speed of the driving motor in the first mode and the second mode are determined according to the laundry weight in the drum. Specifically, before step S410 is performed, the following steps are performed: acquiring the weight of clothes in the drum; the forward rotation speed and the reverse rotation speed of the driving motor in the first mode and the second mode are determined according to the laundry weight. Since the greater the weight of the laundry in the drum, the greater the wind resistance, and the smaller the weight of the laundry in the drum, the wind resistance is also the smaller, in this embodiment, the forward rotation speed and the reverse rotation speed are configured to be positively correlated with the weight of the laundry, so that the rotation speed of the driving motor is adapted to the actual demand.
In step S430, it is determined whether the laundry is dried. If the clothes are judged to be dried, the drying program is ended, and if the clothes are judged to be not dried, the drying program is continuously operated.
As shown in fig. 6, in one embodiment of the present application, step S430 includes steps S610 to S630, which are described in detail below:
in step S610, a laundry humidity value h of laundry in the drum for a preset period tn is acquired.
In detail, a humidity sensor may be provided on a sidewall of the drum or an air outlet of the drum, and a laundry humidity value is detected by the humidity sensor, thereby achieving acquisition of the laundry humidity value h of laundry in the drum within a preset time period tn.
In step S620, it is determined whether the laundry humidity value h at all times within the preset time period tn is less than or equal to the target humidity value h1, if yes, step S630 is entered; otherwise (i.e. at least one moment when the humidity value h of the clothes is greater than the target humidity value h 1), judging that the clothes are not dried, and continuing to operate the drying program.
In step S630, it is determined that the laundry has been dried, and the drying process is ended.
The preset time period tn is flexibly configured according to the actual operation condition of the clothes drying equipment, and is illustratively 3 minutes. The target humidity value h1 is flexibly configured according to the actual operation condition of the clothes drying device, and the target humidity value h1 is exemplified by the water content of clothes being 0% -1%.
In the embodiment shown in fig. 6, by increasing the number of humidity detections in a given period of time, only if the detected humidity value of the laundry at all times in the given period of time is less than or equal to the target humidity value, it is determined that the laundry is dried, and the humidity value of the laundry at any time is greater than the target humidity value, and it is determined that the laundry is not dried, it is possible to prevent erroneous determination that the laundry is dried in the case that the laundry is not dried, and to prevent uneven drying of the laundry due to detection errors of the humidity sensor or local aggregation of the laundry.
As shown in fig. 7, in one embodiment of the present application, step S430 includes steps S710 to S750, which are described in detail below:
in step S710, a laundry humidity value h of laundry in the drum for a preset period tn is acquired.
In step S720, it is determined whether the laundry humidity value h at all times within the preset time period tn is less than or equal to the target humidity value h1, if yes, step S730a is entered; otherwise (i.e., there is at least one moment when the laundry humidity value h is greater than the target humidity value h 1), step S730b is performed.
In step S730a, it is determined that the laundry has been dried, and the drying process is ended.
In step S730b, the return air temperature and the suction air temperature are obtained, and the process proceeds to step S740.
In step S740, the return air temperature increase rate L and the temperature difference Δt between the return air temperature and the suction air temperature are calculated.
Wherein, the return air temperature is the air-out temperature of cylinder. When the humidity of the clothes in the roller is high, the return air temperature is low, when the humidity of the clothes in the roller is low, the return air temperature becomes high, and the rising speed of the return air temperature is faster and faster, so that the return air temperature increasing rate L is gradually increased. Therefore, the return air temperature increase rate L can be used as a clothes drying judging condition.
The suction temperature is the heat exchanger temperature at the inlet of the heat pump system, i.e. at the inlet of the compressor. When the humidity of clothes in the drum is high, the air suction temperature is almost equal to the return air temperature, namely, the temperature difference delta T between the return air temperature and the air suction temperature is small. The configuration air suction temperature gradually decreases along with the drying of clothes, the return air temperature gradually increases, the temperature difference delta T is larger and larger, and finally the maximum value is reached. Therefore, the temperature difference deltat between the return air temperature and the suction air temperature can be used as the drying condition of the clothes.
In step S750, it is determined whether the return air temperature increase rate L is greater than or equal to a preset increase rate L0 or the temperature difference Δt between the return air temperature and the intake air temperature is greater than or equal to a preset difference T3, if yes (i.e., one or both of them are satisfied), step S730a is entered; otherwise (i.e. none of them is satisfied), it is determined that the laundry is not dried, and the drying program is continued to be operated.
Wherein the preset increasing rate L0 is flexibly configured according to the actual operation condition of the clothes drying apparatus, and the preset increasing rate L0 is an increase in temperature by 5 ℃ within 3 min. The preset difference T3 is also flexibly configured according to the actual operation of the laundry drying apparatus, and the preset difference T3 is, for example, 20 ℃.
In the embodiment shown in fig. 7, unlike the embodiment shown in fig. 6, if the laundry humidity value h at all times within the preset time period tn is not equal to or less than the target humidity value h1, further performing the temperature detection judging logic can prevent inaccurate laundry humidity detection caused by the influence of the humidity voltage due to the fluctuation of the power grid of the humidity sensor, and prevent excessive drying of the laundry due to erroneous judgment of not drying the laundry in the case that the laundry is dried.
Fig. 8 is a flowchart of a clothes drying method according to an embodiment of the present application, and referring to fig. 8, the clothes drying method at least includes steps S810 to S840, which are described in detail as follows:
in step S810, four judgment parameters of the drying program running time T, the exhaust temperature T1, the return air temperature T2 and the clothes humidity value h are obtained, whether the drying program running time T is less than or equal to a preset running time T0 or the exhaust temperature T1 is less than or equal to a preset temperature T10 or the return air temperature T2 is less than or equal to a preset temperature T20 or the clothes humidity value h is more than or equal to a preset humidity value h0 is judged, if yes (namely, one judgment parameter or more than one judgment parameter is met), step S820a is entered; otherwise (i.e., none of the judgment parameters is satisfied), the process proceeds to step S820b.
In step S820a, the driving motor is controlled to operate in a first mode.
In step S820b, the driving motor is controlled to operate in the second mode.
In step S830, a laundry humidity value h of the laundry in the drum in a preset time period tn is obtained, and whether the laundry humidity value h at all times in the preset time period tn is less than or equal to a target humidity value h1 is determined, if yes, step S840a is entered; otherwise (i.e., there is at least one moment when the laundry humidity value h is greater than the target humidity value h 1), step S840b is performed.
In step S840a, it is determined that the laundry has been dried, and the drying process is ended.
In step S840b, the return air temperature and the suction air temperature are obtained, and the return air temperature increasing rate L and the temperature difference Δt between the return air temperature and the suction air temperature are calculated, and then it is determined whether the return air temperature increasing rate L is greater than or equal to the preset increasing rate L0 or the temperature difference Δt between the return air temperature and the suction air temperature is greater than or equal to the preset difference T3, if yes (i.e. one or both of them are satisfied), step S840a is entered; otherwise (i.e., none of them is satisfied), it is determined that the laundry is not dried, and the process returns to step S830, and the drying process is continued.
