[0059] Existing clothes drying equipment can remove dust and lint attached to clothes by beating the clothes and blowing hot air at the end of the drying process, thus removing lint and dust. However, this method does not analyze the actual particle situation and clothing information of the clothes, so the dust removal method adopted cannot completely remove the particles.

[0060] To this end, the present invention provides a method for removing dust from clothes, the method comprising: obtaining a first particle concentration and internal detection information of a clothes drying device; determining a particle concentration threshold based on the internal detection information; determining a comparison result based on the first particle concentration and the particle concentration threshold; and adjusting a first control parameter of the clothes drying device based on the comparison result. The present invention first obtains the particle concentration and internal detection information of the clothes drying device, and determines the particle concentration threshold through the internal detection information, and then adjusts the first control parameter of the clothes drying device according to the comparison relationship between the particle concentration and the particle concentration threshold, so as to remove dust and lint attached to the clothes, improve the cleanliness of the clothes, further improve the drying effect, and enhance the user experience.

[0061] See attached Figure 1 , Figure 1It is a schematic flow chart of main steps of a method for removing dust from clothes according to an embodiment of the present invention.

[0062] like Figure 1 As shown, the clothing dust removal method in the embodiment of the present invention mainly includes the following steps S101 to S104.

[0063] Step S101: obtaining a first particle concentration and internal detection information of a clothes drying device.

[0064] In this embodiment, the particulate matter may be dust, lint or lint, etc. The first particulate matter concentration is collected by a particulate matter concentration sensor installed in the drying device, and the internal detection information is obtained by a detection sensor in the drying device. The detection sensor may be a weight sensor, a humidity sensor, a camera and a particulate matter particle size sensor.

[0065] Step S102: determining a particle concentration threshold based on the internal detection information.

[0066] In this embodiment, the particle concentration threshold is determined by collecting internal detection information, such as at least one of clothing humidity information, clothing material information, clothing weight information and particle size.

[0067] Step S103: determining a comparison result based on the first particle concentration and the particle concentration threshold.

[0068] In this embodiment, the comparison result is determined according to a comparison relationship between the first particle matter concentration and the particle matter concentration threshold.

[0069] Step S104: adjusting a first control parameter of the clothes drying device based on the comparison result.

[0070] Based on the above steps S101 to S104, the particle concentration and internal detection information in the drying device are first collected, and the particle concentration threshold is determined through at least one of the internal detection information such as clothing humidity information, clothing material information, clothing weight information and particle size. Then, the first control parameter of the drying device is adjusted according to the comparison relationship between the first particle concentration and the particle concentration threshold to remove dust and lint attached to the clothes, improve the cleanliness of the clothes, further improve the drying effect, and enhance the user experience.

[0071] The above steps S101 to S104 are further explained below.

[0072] With respect to step S101 , a first particle concentration and internal detection information of the clothes drying device are obtained.

[0073] In this embodiment, the first particle concentration is collected by a particle concentration sensor installed in the clothes drying device. The particle concentration sensor may be a dust concentration sensor, which can obtain the concentration of particles such as dust, lint or lint. Specifically, the particle concentration sensor emits light into the clothes drying device, and the suspended particles in the clothes drying device are irradiated by the light to generate scattered light. The intensity of the scattered light is proportional to the mass concentration of the particles. The first particle concentration is obtained by measuring the intensity of the scattered light and applying mass concentration conversion. The internal detection information is obtained by a detection sensor in the clothes drying device. The detection sensor may be a weight sensor, a humidity sensor, a camera, a particle size sensor, etc.

[0074] For step S102, in one embodiment, the internal detection information includes at least one of clothing humidity information, clothing material information, clothing weight information and particle size; determining the particle concentration threshold based on the internal detection information includes: determining a first concentration threshold based on the clothing humidity information; determining a first coefficient based on the clothing material information; determining a second coefficient based on the clothing weight information; determining a third coefficient based on the particle size; determining the particle concentration threshold based on the product of at least one of the first coefficient, the second coefficient and the third coefficient and the first concentration threshold.

[0075] Specifically, the humidity information of clothing is collected through the humidity sensor installed in the drying device; the image information of clothing is collected through the camera, and the material information of clothing is identified based on the image information of clothing through a pre-trained neural network model; the weight information of clothing is collected through the weight sensor; and the particle size sensor is used to collect the particle size of particles floating in the drying device.

[0076] A first concentration threshold is determined according to clothing humidity information and a preset humidity concentration relationship, wherein the preset humidity concentration relationship is a corresponding relationship between humidity and concentration determined through offline experiments; and a first coefficient corresponding to the clothing material in the first concentration relationship is obtained by matching clothing material information with the clothing material of the first concentration relationship, wherein the first coefficient is a particle concentration coefficient, and the first concentration relationship is a relationship between the clothing material and the first coefficient obtained through offline experiments. The first concentration relationship may be as shown in Table 1.

[0077] Clothing material … silk … wool … Cotton and Linen … The first coefficient … <![CDATA[m1]]> … <![CDATA[m2]]> … <![CDATA[m3]]> …

[0078] Table 1

[0079] Then, by matching the clothing weight information with the clothing weight of the second concentration relationship, the second coefficient corresponding to the clothing weight in the second concentration relationship is obtained. The second coefficient is the particle concentration coefficient. The second concentration relationship is the relationship between the clothing weight and the second coefficient obtained through offline experiments. The second concentration relationship can be shown in Table 2.

[0080] Clothing weight Less than 0.5kg 0.5–2kg More than 2kg The second coefficient <![CDATA[n1]]> <![CDATA[n2]]> <![CDATA[n3]]>

[0081] Table 2

[0082] Then match the particle size with the third concentration relationship to obtain the third coefficient corresponding to the particle size in the third concentration relationship. The third coefficient is the particle concentration coefficient. The third concentration relationship is the relationship between the particle size and the third coefficient obtained through offline experiments. The third concentration relationship can be shown in Table 3.

[0083] Particle size Less than 2.5μm 2.5-10μm More than 10μm The third coefficient <![CDATA[k1]]> <![CDATA[k2]]> <![CDATA[k3]]>

[0084] Table 3

[0085] At least one of the first coefficient, the second coefficient and the third coefficient is multiplied by the first concentration threshold, and the product is used as the particle concentration threshold. It can be understood that when the clothing weight information, clothing material information and particle size can all be obtained and the first coefficient, the second coefficient and the third coefficient can be determined, the particle concentration threshold calculated by multiplying the three coefficients by the first concentration threshold is the most accurate. For example, if the determined first concentration threshold is 90, the clothing material information is wool material, the clothing weight information is greater than 2 kg, and the particle size is less than 2.5 μm, then the particle concentration threshold is 90*m2*n3*k1.

[0086] In the case where the clothing weight information, clothing material information and particle size are not completely obtained, the corresponding coefficient can also be determined according to the obtained data, and the particle concentration threshold is calculated by multiplying the corresponding coefficient with the first concentration threshold. Under the same clothing humidity condition, the heavier the clothing weight, the more dust-absorbing the clothing material, and the larger the particle size, the higher the calculated particle concentration threshold.

[0087] The particle concentration threshold is closely related to the weight, material and particle size of the clothes. The particle concentration threshold of the clothes at the current humidity is determined by the humidity information, material information, weight information and particle size of the clothes. The particle concentration threshold can be determined according to the actual situation of the clothes and the situation of the particles, providing an accurate judgment basis for the subsequent adjustment of the parameters of the drying equipment according to the comparison results of the particle concentration and the particle concentration threshold.

[0088] With respect to step S103 , a comparison result is determined based on the first particle concentration and the particle concentration threshold.

[0089] Specifically, the comparison result is a size comparison relationship between the first particle matter concentration and the particle matter concentration threshold, including that the first particle matter concentration is greater than the particle matter concentration threshold, and the first particle matter concentration is less than or equal to the particle matter concentration threshold.

[0090] For step S104, adjusting the first control parameter of the drying device based on the comparison result includes: obtaining a first consecutive number of comparison results; determining an adjustment ratio based on the first consecutive number of comparison results and a preset adjustment relationship, wherein the preset adjustment relationship is a corresponding relationship between the first consecutive number of times and the adjustment ratio; and adjusting the first control parameter of the drying device based on the adjustment ratio.

[0091] The first consecutive number of comparison results is the accumulation of the consecutive number of occurrences of the relevant comparison results after each execution of the first control parameter of the clothes drying device corresponding to the comparison result is completed, and the comparison results include the first particle concentration being greater than the particle concentration threshold and the first particle concentration being less than or equal to the particle concentration threshold. For example, when the comparison result is that the first particle concentration is greater than the particle concentration threshold, after the corresponding first control parameter adjustment procedure is executed, the first consecutive number of comparison results that the first particle concentration is greater than the particle concentration threshold is increased by one.

[0092] After determining the comparison result, the first consecutive number of comparison results is obtained, and the adjustment ratio is determined according to the first consecutive number of comparison results and a preset adjustment relationship. The preset adjustment relationship is the corresponding relationship between the first consecutive number and the adjustment ratio determined by offline experiments. The preset adjustment relationship can be shown in Table 4.

[0093] First consecutive number 1 2 … N-1 N Adjust the ratio M M-1 … 10％ 0％

[0094] Table 4

[0095] For example, when the first consecutive number of comparison results is 2, the adjustment ratio is M-1, and the adjustment ratio can be set as a percentage multiple, such as M is 100%, M-1 is 90%... and so on, when the first consecutive number of comparison results is the Nth time, the adjustment ratio is 0%, that is, when the first consecutive number of comparison results is greater than or equal to the preset first number threshold N, the first control parameter of the clothes drying device is no longer adjusted. The adjustment ratio is determined according to the first consecutive number of comparison results of the particle concentration and the particle concentration threshold, so as to achieve targeted adjustment of the first control parameter of the clothes drying device based on the particle situation in the clothes drying device, thereby improving the particle removal effect.

[0096] In one embodiment, the first control parameter includes a first wind speed and a first rotational speed of the drying device; when the comparison result is that the first particle concentration is greater than the particle concentration threshold, adjusting the first control parameter of the drying device based on the adjustment ratio includes: obtaining the first wind speed and the first rotational speed of the drying device; determining a wind speed adjustment value based on the product of the first wind speed and the adjustment ratio, and determining a rotational speed adjustment value based on the product of the first rotational speed and the adjustment ratio; increasing the first wind speed based on the wind speed adjustment value, and reducing the first rotational speed based on the rotational speed adjustment value.

[0097] Specifically, the first control parameter includes a first wind speed and a first rotational speed of the clothes drying device, the first wind speed is the fan wind speed, and the first rotational speed is the motor rotational speed; when the first particle concentration is greater than the particle concentration threshold, it is determined that the particles currently attached to the clothes are small, while the particles floating in the clothes drying device are large, and the discharge of dust in the clothes drying device needs to be accelerated. At this time, the first wind speed and the first rotational speed of the clothes drying device are obtained, and the first wind speed and the first rotational speed can be the current wind speed and the current rotational speed of the clothes drying device, and the wind speed adjustment value is determined by the product of the first wind speed and the adjustment ratio, and the first wind speed is increased according to the wind speed adjustment value, and the rotational speed adjustment value is determined by the product of the first rotational speed and the adjustment ratio, and the first rotational speed is reduced according to the rotational speed adjustment value.

[0098] For example, if the first wind speed is 3.8 m / s and the determined adjustment ratio is 40%, then the first wind speed is multiplied by the adjustment ratio, 3.8*40%=1.52. 1.52 is used as the wind speed adjustment value to increase the first wind speed by 1.52 m / s. The increased wind speed is 3.8+1.52=5.32 m / s.

[0099] When the first particle concentration is greater than the particle concentration threshold, it means that there are more particles floating in the dryer. Increasing the wind speed can speed up the air flow in the dryer and blow the particles from the inner drum of the dryer to the outside of the drum. Reducing the rotation speed can shake the clothes by tumbling back and forth, so that the particles inside the clothes can be lifted up and floated, and then blown from the inner drum to the outside of the drum by the fan.

[0100] In one embodiment, the first control parameter includes the second wind speed and the second rotational speed of the drying device; when the comparison result is that the first particle concentration is less than or equal to the particle concentration threshold, adjusting the first control parameter of the drying device based on the adjustment ratio includes: obtaining the second wind speed and the second rotational speed of the drying device; determining a wind speed adjustment value based on the product of the second wind speed and the adjustment ratio, and determining a rotational speed adjustment value based on the product of the second rotational speed and the adjustment ratio; reducing the second wind speed based on the wind speed adjustment value, and increasing the second rotational speed based on the rotational speed adjustment value.

[0101] Specifically, when the first particle concentration is less than or equal to the particle concentration threshold, it is determined that there are fewer particles floating in the drum and the particles may be attached to the clothes. At this time, the second wind speed and the second rotation speed are obtained, and the second wind speed and the second rotation speed may be the current wind speed and the current rotation speed of the clothes drying device, and then the wind speed adjustment value is determined based on the product of the second wind speed and the adjustment ratio, and the rotation speed adjustment value is determined based on the product of the second rotation speed and the adjustment ratio, and the second wind speed is reduced according to the wind speed adjustment value, and the second rotation speed is increased according to the rotation speed adjustment value.

[0102] When the first particle concentration is less than or equal to the particle concentration threshold, it is determined that there are fewer particles floating in the drum and the particles may be attached to the clothes. At this time, the rotation speed is increased to increase the tumbling speed of the clothes in the drum so that the particles attached to the clothes float up. Reducing the wind speed can prevent the particles from being attached to the clothes and unable to float due to excessive wind speed.

[0103] In one embodiment, the method further includes: after executing the step of "adjusting the first control parameter of the drying device based on the comparison result", controlling the first consecutive number of the comparison result to be increased by one; and / or when the first consecutive number of the comparison result is greater than the first number threshold, obtaining a third wind speed and a third rotational speed, and keeping the drying device running at the third wind speed and the third rotational speed until the comparison result meets a preset condition.

[0104] Specifically, after the first control parameter of the drying equipment is adjusted, the first consecutive number of determined comparison results is increased by one. For example, the comparison result determined this time is that the first particle concentration is less than or equal to the particle concentration threshold, and the first consecutive number obtained is 5 times. Then, after the first control parameter is adjusted, the first consecutive number is increased by one, and the first consecutive number becomes 6 times.

[0105] The preset condition means that if the comparison result determined next time is inconsistent with the comparison result determined this time, it is determined that the preset condition is met.

[0106] When the first consecutive number of comparison results is greater than the first number threshold, the third wind speed and the third rotational speed are obtained, and the third wind speed and the third rotational speed may be the current wind speed and the current rotational speed of the drying device. At this time, the first control parameter is no longer adjusted, and the drying device is controlled to maintain the third wind speed and the third rotational speed until the comparison result meets the preset conditions.

[0107] For example, the comparison result determined this time is that the first particle concentration is less than or equal to the particle concentration threshold, the first consecutive number of times obtained is 11 times, and the first consecutive number of times is greater than the set first number threshold of 10 times. At this time, the first control parameter is not adjusted, and the drying equipment is controlled to maintain the third wind speed and the third speed. Until the next comparison result determined becomes that the first particle concentration is greater than the particle concentration threshold, the next round of adjustment procedure for the first control parameter is started.

[0108] like Figure 4 As shown, in one embodiment, a dust sensor is used to detect the particle concentration, the particle concentration is the first particle concentration in the aforementioned embodiment, and the critical concentration of the current humidity is the particle concentration threshold in the aforementioned embodiment; the particle concentration is compared with the critical concentration of the current humidity, and if the particle concentration is higher than the critical concentration of the current humidity, it is determined whether the particle concentration is higher than the critical concentration of the current humidity for N consecutive times, and if not, the adjustment measures of increasing the wind speed and reducing the rotation speed are taken; if so, the particle concentration is continuously detected until the particle concentration is lower than the critical concentration of the current humidity. After executing the adjustment procedure of increasing the wind speed and reducing the rotation speed, the number of consecutive times that the particle concentration is higher than the critical concentration of the current humidity is increased by one.

[0109] When the particle concentration is lower than the critical concentration of the current humidity, determine whether the particle concentration is lower than the critical concentration of the current humidity for N consecutive times. If not, take the adjustment measures of increasing the rotation speed and reducing the wind speed; if so, continue to detect the particle concentration until the particle concentration is higher than the critical concentration of the current humidity. After executing the adjustment procedures of increasing the rotation speed and reducing the wind speed, the number of consecutive times that the particle concentration is lower than the critical concentration of the current humidity is increased by one.

[0110] In one embodiment, after the drying program is started for a preset time and the humidity change rate of the clothes is less than a humidity change rate threshold, the method further includes: obtaining a second particle matter concentration within a preset time period; determining the particle matter concentration change rate and the concentration change rate threshold based on the second particle matter concentration within the preset time period; and selectively controlling the drying device based on the particle matter concentration change rate and the concentration change rate threshold.

[0111] Specifically, after the drying program is started for a preset time, the drying program is about to end, the humidity of the dried clothes tends to be stable, and the corresponding particle concentration threshold also tends to be stable. At this time, the drying equipment maintains the current state operation and obtains the second particle concentration of the preset time period. The second particle concentration can be multiple second particle concentrations within the preset time period. The particle concentration change rate is calculated based on the multiple second particle concentrations, and the concentration change rate threshold is determined based on the second particle concentration collected for the last time within the preset time period. Then, based on the comparison relationship between the particle concentration change rate and the concentration change rate threshold, the drying equipment is controlled to choose to adjust the second control parameter or end the drying program.

[0112] like Figure 5 As shown, in one embodiment, the rate of change of the particle matter concentration is first calculated, and the rate of change of the particle matter concentration is the aforementioned rate of change of the particle matter concentration, and the rate of change of the particle matter concentration is compared with a current concentration rate of change threshold, and the rate of change threshold is the aforementioned concentration rate of change threshold. When the rate of change of the particle matter concentration is higher than the rate of change threshold, it is determined whether the rate of change of the particle matter concentration is higher than the rate of change threshold for M consecutive times. If not, the clothes drying device is controlled to extend the drying time; if so, the rate of change of the particle matter concentration is continuously calculated until the rate of change of the particle matter concentration is lower than the rate of change threshold.

[0113] After the adjustment procedure for extending the drying time is executed, the number of consecutive times that the rate of change of the particle concentration is higher than the rate of change threshold is increased by one.

[0114] When the change rate of the particle concentration is higher than the change rate threshold, the clothes drying device is controlled to end the drying process.

[0115] By analyzing the current particle removal status by the rate of change of particle concentration within a preset time period before the end of drying, the clothes drying equipment can be further controlled to take measures according to the analysis results before the end of drying to improve the particle removal effect.

[0116] In one embodiment, the clothes drying device is selectively controlled based on the particle matter concentration change rate and the concentration change rate threshold, including: when the particle matter concentration change rate is greater than the concentration change rate threshold, obtaining a second consecutive number of times that the particle matter concentration change rate is greater than the concentration change rate threshold; determining whether the second consecutive number is greater than the second number threshold, and if not, controlling the clothes drying device to adjust a second control parameter; or when the particle matter concentration change rate is less than or equal to the concentration change rate threshold, controlling the clothes drying device to end the drying program.

[0117] The second consecutive number of times is the number of consecutive occurrences of the particle concentration change rate being greater than the concentration change rate threshold. After executing the step of "controlling the drying device to adjust the second control parameter", the second consecutive number of times the particle concentration change rate is controlled to be greater than the concentration change rate threshold increases by one.

[0118] Specifically, when the particle matter concentration change rate is greater than the concentration change rate threshold, it means that the current particle matter concentration in the drying device is still high, and the drying device needs to be controlled to adjust the second control parameter. Adjusting the second control parameter can be to extend the drying time. At this time, the second consecutive number of times that the particle matter concentration change rate is greater than the concentration change rate threshold is obtained, and it is determined whether the second consecutive number is greater than the second number threshold. If not, the drying device is controlled to extend the drying time according to the preset time, and the preset time can be set to 1 minute.

[0119] If the second consecutive number is greater than the second number threshold, the clothes dryer is controlled to maintain the current operating state, and the particle concentration change rate and the concentration change rate threshold are monitored according to the preset time period until the particle concentration change rate is less than the concentration change rate threshold, and the clothes dryer is controlled to end the drying process. When the particle concentration change rate is less than or equal to the concentration change rate threshold, it means that the particle concentration in the current clothes dryer is basically stable and there are few particles, and the clothes dryer can be controlled to end the drying process.

[0120] Before the end of the drying program, the particle removal status of the clothes is judged according to the particle concentration change rate, and measures can be taken to extend the drying time when the particle concentration change rate is high, which can further improve the particle removal effect. When the particle concentration change rate is lower than the concentration change rate threshold, the drying program is terminated in time to achieve the purpose of saving energy.

[0121] See attached Figure 2 , Figure 2 1 is a schematic diagram of a complete process flow for adjusting a first control parameter according to an embodiment of the present invention.

[0122] like Figure 2 As shown, when adjusting the first control parameter, the laundry dust removal method of the present invention comprises the following steps:

[0123] Step S201: Start the program.

[0124] Step S202: Acquire the first particle concentration and internal detection information. In this embodiment, the internal detection information includes clothing humidity information, clothing material information, clothing weight information and particle size of the particles.

In this embodiment, the product of the first wind speed and the adjustment ratio is used as the wind speed adjustment value, and the product of the first rotational speed and the adjustment ratio is used as the speed adjustment value.

[0132] Step S210: adjusting the first control parameter based on the wind speed adjustment value and the rotation speed adjustment value. In this embodiment, the first control parameter includes a first wind speed and a first rotation speed, the first wind speed is increased based on the wind speed adjustment value, and the first rotation speed is decreased based on the rotation speed adjustment value.

[0133] Step S211: increase the first consecutive number of the first comparison result by one, and execute step S202. In this embodiment, after the first control parameter is adjusted, the first consecutive number of the first comparison result is increased by one.

[0134] Step S212: Control the clothes drying device to operate at the third wind speed and the third rotation speed, and execute step S202. In this embodiment, the third wind speed is the current wind speed, and the third rotation speed is the current rotation speed. When the first consecutive number of the first comparison result is greater than N times, the wind speed and the rotation speed of the clothes drying device are no longer adjusted, and the clothes drying device is controlled to operate at the third wind speed and the third rotation speed.

[0135] Step S213: Obtain the first consecutive number of second comparison results. In this embodiment, when the first particle concentration is less than or equal to the particle concentration threshold, the first consecutive number of second comparison results is obtained, and the second comparison result is that the first particle concentration is less than or equal to the particle concentration threshold.

[0136] Step S214: Determine whether the first consecutive number of the second comparison result is greater than N times, if so, execute step S220; if not, execute step S215.

[0137] Step S215: determining an adjustment ratio based on the first consecutive number of second comparison results and a preset adjustment relationship.

[0138] Step S216: Acquire a second wind speed and a second rotation speed. In this embodiment, the second wind speed may be the current wind speed, and the second rotation speed may be the current rotation speed.

[0139] Step S217: Determine the wind speed adjustment value based on the second wind speed and the adjustment ratio, and determine the speed adjustment value based on the second rotational speed and the adjustment ratio. In this embodiment, the wind speed adjustment value is determined according to the product of the second wind speed and the adjustment ratio, and the speed adjustment value is determined according to the product of the second rotational speed and the adjustment ratio.

[0140] Step S218: adjusting the first control parameter based on the wind speed adjustment value and the rotation speed adjustment value. In this embodiment, the first control parameter includes a second wind speed and a second rotation speed, the second wind speed is reduced based on the wind speed adjustment value, and the second rotation speed is increased based on the rotation speed adjustment value.

[0141] Step S219: increase the first consecutive number of the second comparison result by one, and execute step S202. In this embodiment, after adjusting the first control parameter, the first consecutive number of the second comparison result is increased by one.

[0142] Step S220: Control the clothes drying device to operate at a third wind speed and a third rotation speed, and execute step S202.

[0143] See attached Figure 3 , Figure 3 1 is a schematic diagram of a complete flow chart of steps for adjusting the second control parameter according to an embodiment of the present invention.

[0144] like Figure 3 As shown, when adjusting the second control parameter, the laundry dust removal method of the present invention comprises the following steps:

[0145] Step S301: After the drying program is started for a preset time, and the humidity change rate of the clothes is less than the humidity change rate threshold, execute step S302.

[0146] Step S302: Obtain the second particle concentration within a preset time period. In this embodiment, after the drying program is started for a preset time, the humidity of the dried clothes tends to be stable, and the corresponding particle concentration threshold also tends to be stable. At this time, the drying device maintains the current state operation, and the second particle concentration of the preset time period is obtained.

[0147] Step S303: Determine the particle concentration change rate based on the second particle concentration within the preset time period. In this embodiment, the second particle concentration may be a plurality of second particle concentrations within the preset time period, and the particle concentration change rate is calculated based on the collected plurality of second particle concentrations.

[0148] Step S304: Determine a concentration change rate threshold value based on the second particle concentration within a preset time period. In this embodiment, the concentration change rate threshold value is determined based on the second particle concentration collected last time within the preset time period.

[0149] Step S305: determine whether the particle concentration change rate is greater than the concentration change rate threshold, if so, execute step S306; if not, execute step S310. In this embodiment, the clothes drying device is controlled to adjust the second control parameter or end the drying process according to the comparison relationship between the particle concentration change rate and the concentration change rate threshold.

[0150] Step S306: Obtain the second consecutive number of the third comparison result. In this embodiment, the third comparison result is that the particle concentration change rate is greater than the concentration change rate threshold.

[0151] Step S307: Determine whether the second consecutive number of the third comparison result is greater than P times, if so, execute step S302; if not, execute step S308.

[0152] Step S308: adjusting the second control parameter of the clothes drying device according to the preset time. In this embodiment, adjusting the second control parameter is to extend the drying time, and specifically, the drying time of the clothes drying device can be extended according to the preset time, such as 1 minute.

[0153] Step S309: increase the second consecutive number of the third comparison result by one, and execute step S302. In this embodiment, after adjusting the second control parameter, the second consecutive number of the third comparison result is increased by one.

[0154] Step S310: End the drying process. In this embodiment, when the particle concentration change rate is less than or equal to the concentration change rate threshold or the second consecutive number of the third comparison result is greater than P times, the clothes drying device is controlled to end the drying process.
