It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0026] In addition, it also needs to be explained that in the description of the embodiments of the present application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0028] The solutions for processing the clogging of the filtering device of the laundry processing apparatus mentioned in the background art at least have the following technical problems:

[0029] In order to improve the drying speed of the laundry, most users will choose to use the laundry processing apparatus to perform drying treatment on the laundry. However, during the drying treatment of the laundry by the laundry processing apparatus, the lint on the laundry will be suspended on the filtering device of the laundry processing apparatus along with the air flow. As the load weight increases, the number of the lint in a single cycle increases, and as time goes by, the lint will be accumulated on the filtering device, causing the clogging of the filtering device, thereby reducing the air volume of the laundry drying apparatus, degrading the drying performance, lengthening the drying time of the laundry, and even in the extreme case, the heat pump system of the laundry processing apparatus in the laundry processing apparatus cannot dissipate heat, the local temperature is too high, causing a safety accident, which will greatly affect the user experience.

[0030] In the prior art, in order to solve the problem of the clogging of the filtering device of the laundry drying apparatus by the lint, it is usually reminded in the instruction manual of the laundry processing apparatus that the maximum load for a single drying, so as to ensure that the filtering device is not completely clogged after the end of a single drying process. However, this method cannot accurately detect the clogging of the filtering device, so as to ensure that the user can clean the clogging on the filtering device in time.

[0031] In view of the above problems, the present application provides a control method of a laundry processing apparatus, the core idea of which is to determine the gas humidity in the air outlet channel by monitoring the humidity and temperature in the air outlet channel, and then determine the gas flow of the air outlet channel according to the gas humidity, and compare the gas flow with a preset air volume threshold to determine the clogging condition of the filtering device, and output an alarm information when the filtering device is clogged, so that the user can clean the clogging on the filtering device in time according to the alarm information, so as to achieve the purpose of reminding the user to clean the clogging on the filtering device when the clogging on the filtering device affects the performance of the laundry processing apparatus, thereby ensuring the performance of the laundry processing apparatus.

[0032] In a possible implementation, the control method of the laundry processing apparatus provided in the embodiment can be applied in an application scenario. Figure 1An application scenario diagram of the control method of the laundry treatment apparatus provided by the embodiments of the present application is shown in Figure 1 The laundry treatment apparatus can include an inner drum, a filter device, an evaporator, a condenser, and a fan. An air outlet of the inner drum is communicated with the fan through an air outlet passage. The evaporator and the condenser are arranged in the air outlet passage. The filter device is arranged between the evaporator and the inner drum. An air outlet of the fan is communicated with an air inlet of the inner drum through an air inlet passage. When the laundry treatment apparatus is started, air in the inner drum enters the filter device through the air outlet of the inner drum. The filter device filters out the lint and other blockages in the air sent by the inner drum. Then, the air with the blockages filtered out enters the evaporator, which performs cooling and dehumidification. Then, the air after the cooling and dehumidification enters the condenser, which performs warming. Finally, the air after the warming is sent into the inner drum by the fan, taking away the moisture of the clothes in the inner drum, thereby completing the drying treatment of the clothes, Figure 1 The arrows in the figure are used to represent the flow direction of the air.

[0033] In the above scenario, the filter device can filter out the lint and other blockages carried in the air of the inner drum, thereby avoiding the lint in the air from entering the circulation passage, causing the circulation passage to be blocked and the performance of the laundry treatment apparatus to be poor. Therefore, the gas flow of the air outlet passage can be determined by the gas moisture content in the air outlet passage of the inner drum and the amount of water evaporated by the evaporator within a preset time length, so as to determine the blockage condition of the filter device by the gas flow in the air outlet passage, and output an alarm information to remind the user to timely handle the blockages on the filter device in the case that the gas flow is less than or equal to a preset air volume threshold.

[0034] In the above scenario, in order to determine the gas flow of the air outlet passage, a wet temperature sensor can be arranged before and after the evaporator to determine the gas moisture content before and after the evaporator. Then, the gas flow is determined by the change amount of the gas moisture content before and after the evaporator and the amount of water evaporated by the evaporator within a preset time length.

[0035] In combination with the above scenario, the technical solutions of the control method of the laundry treatment apparatus provided by the present application are described in detail below through several specific embodiments.

[0036] Figure 2 A flow chart of the control method of the laundry treatment apparatus provided by the embodiments of the present application is shown in Figure 2 The control method of the laundry treatment apparatus includes the following steps:

[0037] S201: Determine the gas moisture content in the air outlet passage according to the humidity and temperature in the air outlet passage.

[0038] In this step, the clothes treatment device can be a device with clothes drying function, such as a clothes dryer. The clothes treatment device comprises an inner drum and a fan, an air outlet of the inner drum is communicated with an air inlet of the fan through an air outlet channel, an air inlet of the inner drum is communicated with an air outlet of the fan through an air inlet channel, an evaporator and a condenser are arranged in the air outlet channel, and a filter device is arranged between the evaporator and the inner drum.

[0039] In the above scheme, in order to determine whether the filter device is blocked, the humidity and temperature in the air outlet channel can be determined first, and then the gas moisture content in the air outlet channel is determined according to the humidity and temperature in the air outlet channel, so that the gas flow in the air outlet channel can be further determined, and the blockage of the filter device can be determined according to the gas flow.

[0040] S202: Determine the gas flow according to the gas moisture content and the water evaporated by the evaporator in a preset time length.

[0041] In this step, the gas moisture content can be used to represent the weight of water contained in a unit weight of air. Since the evaporator is arranged in the air outlet channel, in order to determine the gas flow in the air outlet channel, the gas flow can be calculated according to the gas moisture content in the air outlet channel and the water evaporated by the evaporator in a preset time length.

[0042] S203: If the gas flow is less than or equal to a preset air volume threshold, output an alarm information.

[0043] In this step, the alarm information is used to remind the blockage of the filter device. The preset air volume threshold can be a best air volume value that can ensure the performance of the clothes treatment device. For example, the preset air volume threshold can be 50% of the rated air volume of the clothes drying device. Therefore, if the gas flow is less than or equal to the preset air volume threshold, it means that there is too much blockage on the filter device, which has affected the performance of the clothes treatment device. At this time, the drying effect of the clothes treatment device is low, so the alarm information needs to be output to remind the user that the filter device is blocked and needs to be cleaned in time. If the gas flow is greater than the preset air volume threshold, it means that there is no blockage on the filter device or the blockage on the filter device is within an acceptable range. At this time, the performance of the clothes treatment device is not greatly affected, so the clothes treatment device can continue to run.

[0044] The control method of the laundry treatment device provided in the embodiments of the present application determines the gas moisture content in the air outlet channel according to the humidity and temperature in the air outlet channel; determines the gas flow rate according to the gas moisture content and the amount of water evaporated by the evaporator within a preset time length; and outputs an alarm information if the gas flow rate is less than or equal to a preset air volume threshold, the alarm information being used to remind the clogging of the filtering device. The present application determines the gas moisture content in the air outlet channel by monitoring the humidity and temperature in the air outlet channel, and then determines the gas flow rate of the air outlet channel according to the gas moisture content, and compares the gas flow rate with the preset air volume threshold to determine the clogging condition of the filtering device, and outputs the alarm information when the filtering device is clogged, so that the user can clean the clogging on the filtering device in time according to the alarm information, thus the technical solution of the present application can avoid the problem that the performance of the laundry treatment device is reduced due to the failure to clean the clogging in time caused by the user's need to actively check the clogging condition of the filtering device, and achieves the purpose of timely reminding the user to clean the clogging on the filtering device.

[0045] The technical solution of the control method of the laundry treatment device is described in detail below.

[0046] In a possible implementation, the determination of the gas moisture content in the air outlet channel according to the humidity and temperature in the air outlet channel comprises: determining the saturated water vapor partial pressure according to the temperature in the air outlet channel; determining the actual water vapor partial pressure according to the saturated water vapor partial pressure and the humidity in the air outlet channel; and determining the gas moisture content in the air outlet channel according to the actual water vapor partial pressure and the measured atmospheric pressure.

[0047] In this solution, the saturated water vapor partial pressure can be calculated by the Hay and Wexler formula. For example, in the case that the current air temperature is between -100℃ and 0℃, the calculation formula of the saturated water vapor partial pressure P WS may be as follows:

[0048] ln P WS =C1 / T+C2+C3T+C4T+C5T+C6T+C7ln T 2 3 4 +C7ln T

[0049] wherein T can be used to represent the current air temperature, i.e. the dry bulb temperature of the current environment, C1, C2, C3, C4, C5, C6 and C7 are constants, and the values of C1, C2, C3, C4, C5, C6 and C7 can be as follows:

[0050] C1=-5.674 535 9H+03

[0051] C2=6.392 524 7E+00

[0052] ​​C3 = -9.677 843 0 E-03

[0053] C4 = 6.221 570 1 E-07

[0054] C5 = 2.074 782 5 E-09

[0055] C6 = -9.484 024 0 E-13

[0056] C7 = 4.163 501 9 E+00

[0057] In the case that the current temperature is between 0°C and 200°C, the saturated water vapor partial pressure P WS can be calculated by the following formula:

[0058] ln P WS = C8 / T + C9 + C 10 T + C 11 T 2 + C 12 T 3 + C 13 ln T

[0059] wherein T can be used to represent the current temperature, C8, C9, C 10 , C 11 , C 12 , C 13 are constants, and the values of C8, C9, C 10 , C 11 , C 12 , C 13 can be as follows:

[0060] C8 = -5.800 220 6 E+03

[0061] C9 = 1.391 499 3 E+00

[0062] C 10 = -4.864 023 9 E-02

[0063] C 11 = 4.176 476 8 E-05

[0064] C 12 = -1.445 209 3 E-08

[0065] C 13 = 6.545 967 3 E+00

[0066] In the above scheme, after the saturated water vapor partial pressure is determined, the actual water vapor partial pressure can be determined according to the saturated water vapor partial pressure and the humidity in the air outlet channel. The calculation formula of the actual water vapor partial pressure P W may be as follows:

[0067]

[0068] may be used to represent the humidity in the air outlet channel.

[0069] In the above scheme, after the actual water vapor partial pressure is determined, the gas moisture content in the air outlet channel can be determined according to the actual water vapor partial pressure and the measured atmospheric pressure. The calculation formula of the gas moisture content W can be as follows:

[0070]

[0071] wherein P can be used to represent the measured atmospheric pressure, and P can take a value of 101325 pascal (Pa).

[0072] In the above scheme, by determining the gas moisture content in the air outlet channel, the gas flow rate of the air outlet channel can be determined according to the gas moisture content, so that after the gas flow rate is compared with the preset air volume threshold, the clogging condition of the filtering device can be determined, thereby avoiding the problem that the performance of the clothes treatment apparatus is reduced due to the inability to clean the clogging material in time caused by the user needing to actively check the clogging condition of the filtering device, and achieving the purpose of timely reminding the user to clean the clogging material on the filtering device.

[0073] In a possible implementation, the evaporator is further provided with a first humidity temperature sensor and a second humidity temperature sensor. The gas flow rate is determined according to the gas moisture content and the amount of water evaporated by the evaporator within a preset time length, including: obtaining a moisture content change value according to the gas moisture content obtained by the first humidity temperature sensor and the gas moisture content obtained by the second humidity temperature sensor; obtaining the amount of water evaporated by the evaporator within the preset time length; and determining the gas flow rate as a quotient value of the amount of water and the preset time length and the moisture content change value.

[0074] ​In the scheme, since the evaporator can remove moisture from the air sent from the inner cylinder, in order to determine the gas flow in the air outlet channel, a first wet temperature sensor and a second wet temperature sensor can be arranged in front of and behind the evaporator, the humidity and temperature in front of the evaporator are detected by the first wet temperature sensor, that is, the humidity and temperature at the air inlet of the evaporator, and the humidity and temperature behind the evaporator are detected by the second wet temperature sensor, that is, the humidity and temperature at the air outlet of the evaporator. Then the gas moisture content in front of the evaporator is determined according to the humidity and temperature in front of the evaporator, the gas moisture content behind the evaporator is determined according to the humidity and temperature behind the evaporator, and then the moisture content change value in front of and behind the evaporator is determined. As shown in Figure 3

[0075] Figure 3 The layout diagram of the wet temperature sensor provided by the embodiment of the present application is shown in Figure 3 In the above scheme, the filter device, the evaporator and the condenser are arranged in the heat pump shell of the clothes treatment equipment, the filter device is arranged to communicate with the air inlet of the evaporator through the air inlet channel, the first wet temperature sensor is arranged in front of the evaporator, and the second wet temperature sensor is arranged behind the evaporator. Therefore, the humidity and temperature in front of the evaporator can be detected by the first wet temperature sensor, and the humidity and temperature behind the evaporator can be detected by the second wet temperature sensor.

[0076] In the above scheme, the moisture removed by the evaporator (that is, the condensed water) can be discharged into the water tank of the outer cylinder of the clothes treatment equipment through the drain pipe under the heat pump shell of the clothes treatment equipment, and then the condensed water is discharged by the water pump of the clothes treatment equipment. Therefore, when the amount of water evaporated by the evaporator in a preset time period is obtained, the timing can be started when the condensed water enters the water tank and triggers the liquid level sensor, and the timing can be ended when the amount of condensed water reaches a preset water amount value. At this time, the water pump discharges the condensed water, and the time period from the start of timing to the end of timing is the preset time period, and the amount of condensed water discharged (that is, the water amount threshold) is the amount of water evaporated by the evaporator in the preset time period.

[0077] In the above scheme, the calculation formula of the gas flow Q can be as follows:

[0078] Q = m / Δt / ΔD

[0079] Wherein, m can be used to represent the amount of water evaporated by the evaporator in a preset time period, Δt can be used to represent the preset time period, and ΔD can be used to represent the moisture content change value.

[0080] ​In the above scheme, the gas flow rate is determined by the average humidity content of the gas in front of and behind the evaporator, which can ensure the rationality of the final obtained gas flow rate value, avoid the problem of large deviation of the calculation result caused by single numerical calculation, thereby ensuring that the value of the gas flow rate is more reasonable, and further improving the accuracy of judging the blocking condition of the filtering device.

[0081] In a possible implementation, the method further includes: determining a first time point as a time point at which the condensed water of the evaporator enters the water tank after the drying program starts; determining a second time point as a time point at which the amount of the condensed water in the water tank reaches the water amount threshold; determining a preset time length according to the first time point and the second time point; and determining the water amount evaporated by the evaporator in the preset time length as the water amount threshold.

[0082] In the above scheme, the preset time length can be represented by Δt, and the calculation formula of the preset time length can be as follows:

[0083] Δt = t2-t1

[0084] wherein t2 can be used to represent the first time point at which the condensed water enters the water tank to trigger the start timing of the liquid level sensor, and t1 can be used to represent the second time point at which the water amount of the condensed water reaches the water amount threshold.

[0085] In the above scheme, in order to ensure that the value of the gas flow rate is more reasonable, the gas flow rate can be determined by the average humidity content of the gas in front of and behind the evaporator, and therefore the average humidity content of the gas in front of and behind the evaporator can be determined by the preset time length, thereby improving the accuracy of judging the blocking condition of the filtering device.

[0086] In a possible implementation, the humidity content change value is obtained according to the gas humidity content obtained by the first humidity temperature sensor and the gas humidity content obtained by the second humidity temperature sensor, including: determining a first average humidity content according to the gas humidity content obtained by the first humidity temperature sensor in the preset time length; determining a second average humidity content according to the gas humidity content obtained by the second humidity temperature sensor in the preset time length; and obtaining the humidity content change value according to the first average humidity content and the second average humidity content.

[0087] In this scheme, the humidity content change value can be represented by ΔD, and the calculation formula of the humidity content change value can be as follows:

[0088] ΔD = D2-D1

[0089] D2 =∑d2 / Δt

[0090] D1 =∑d1 / Δt

[0091] Wherein, D1 can be used to represent a first average moisture content, d1 can be used to represent a gas moisture content detected by a first wet temperature sensor, D2 can be used to represent a second average moisture content, and d2 can be used to represent a gas moisture content detected by a second wet temperature sensor.

[0092] In the above scheme, in order to ensure that the value of the gas flow is reasonable, the gas flow can be determined by the average moisture content of the gas moisture content in front of and behind the evaporator, thereby improving the accuracy of judging the blocking condition of the filtering device.

[0093] In a possible implementation, the method further includes: if the gas flow is less than or equal to a preset air volume threshold, obtaining a current speed of the fan; and if the current speed is less than a speed threshold, adjusting the speed of the fan to a target speed, the target speed being greater than the current speed.

[0094] In this scheme, the preset air volume threshold can be a best air volume value that can ensure the performance of the clothes processing apparatus, and if the gas flow is less than or equal to the preset air volume threshold, it indicates that there are more blockages on the filtering device, which has affected the performance of the clothes processing apparatus, and at this time, the drying effect of the clothes processing apparatus is low. In order to ensure the drying effect of the clothes processing apparatus, the current speed of the fan in the clothes processing apparatus can be obtained first, and it is determined whether the current speed of the fan is less than the speed threshold, and if the current speed of the fan is less than the speed threshold, it indicates that in the case that the filtering device is blocked, the value of the gas flow can be increased by increasing the speed of the fan, thereby ensuring the drying effect of the clothes processing apparatus and avoiding the problem that the drying effect of the clothes is poor, resulting in poor user experience.

[0095] In the above scheme, the fan can be a variable frequency fan. When the current speed of the fan is increased, it can be increased by a certain value each time, for example, 100 revolutions per minute (rpm) each time. Each time the current speed is increased, the gas flow can be determined again at the target speed until the gas flow is greater than the preset air volume threshold.

[0096] In a possible implementation, the method further includes: if the current speed is greater than or equal to the speed threshold, adjusting the current speed of the fan to the speed threshold.

[0097] In this scheme, the speed threshold is the highest speed of the fan, and when the speed of the fan exceeds the highest speed, the fan will be damaged. Therefore, if the current speed of the fan is greater than or equal to the speed threshold, the current speed of the fan needs to be reduced to the speed threshold, thereby avoiding damage to the fan. After the drying program ends, the user needs to clean the blockages on the filtering device, otherwise, the drying performance of the clothes processing apparatus will be affected when the clothes processing apparatus is used next time.

[0098] In one possible implementation, in addition to setting a first humidity temperature sensor and a second humidity temperature sensor before and after the evaporator as described above, a first humidity temperature sensor can be set before the evaporator and a second humidity temperature sensor can be set after the condenser. Then, the gas flow rate can be obtained using the aforementioned method to determine the blockage status of the filter device.

[0099] In general, the control method for the clothing processing equipment provided in this application can obtain the humidity and temperature before and after the evaporator through humidity and temperature sensors before and after the evaporator, thereby determining the gas flow rate within a preset time period, and determining the blockage of the filter device based on the gas flow rate. Then, when there is a lot of blockage on the filter device, an alarm message is output to remind the user to clean the blockage on the filter device in time. Furthermore, when there is a lot of blockage on the filter device, the fan speed can be increased to ensure the drying performance of the clothing processing equipment. Therefore, the technical solution provided in this application is a technical implementation solution that can both remind the user to clean the blockage on the filter device in time and ensure the drying performance of the clothing processing equipment.
