Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the described embodiments are merely exemplary of some, and not all, of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any inventive step, shall fall within the scope of protection of the present application.

In recent years, the demand of the drum type dryer adopting the heat pump technology in the domestic market is gradually increased, and the sales volume is on the trend of increasing year by year. However, the conventional technology for automatically judging the humidity of clothes in a clothes dryer usually adopts a timing drying method, only simply judges the drying time, stops heating and drying, does not completely consider the damage condition of high temperature to clothes of different fabrics in the drying process, mainly dries the wet clothes for drying, not only damages the clothes, but also wastes electric energy, so that a full-automatic intelligent scheme that the clothes are stopped immediately after being dried cannot be realized, and the user experience is influenced.

In order to solve the above problems, embodiments of the present application provide a control method of a dryer, a control apparatus of a dryer, a storage medium, and a dryer. Referring to fig. 1, fig. 1 is a first flowchart illustrating a control method of a clothes dryer according to an embodiment of the present disclosure. The dryer may be an exhaust type dryer, a heat pump type dryer, a condensing type dryer, or the like. The dryer may include an inner drum for carrying a load, which may be laundry, etc., that a user needs to dry. The specific flow of the control method of the clothes dryer can be as follows:

101, when a drying program of the clothes dryer is started, acquiring a plurality of first humidity values of the inner drum at a plurality of different time points in a first preset time.

In this embodiment, a user may touch a physical key or a virtual key and control the clothes dryer to start operating the drying program through a voice instruction, the drying program may be divided into different working modes according to different target moisture contents after the user load is dried, such as a semi-dry mode, a standard dry mode, or an extra dry mode, the target moisture content of the load in the semi-dry mode may be 6% to 10%, the target moisture content of the load in the standard dry mode may be 2% to 5%, and the target moisture content of the load in the extra dry mode may be 0% to 1%.

It should be noted that, in order to save energy consumption, the drying program of the clothes dryer may have a default operation time, such as 60 minutes, after the drying program reaches the default operation time, the clothes dryer may control the drying program to be turned off. Of course, if the moisture content of the load in the inner cylinder is still higher after the drying program reaches the default operation time, the user can also perform the delay operation before the drying program does not reach the default operation time, so that the drying operation can be continued according to the set delay time after the drying program reaches the default operation time, and the load in the inner cylinder can reach the target moisture content satisfied by the user.

The clothes dryer can comprise a humidity sensor, the humidity sensor can be specifically a bimetallic strip sensing device, a water-resistant humidity-sensitive resistor sensing device, a ceramic pressure sensing device, a humidity-sensitive capacitor sensing device, an epoxy thermistor sensing device and the like, and the humidity sensor can determine the moisture content of the load by representing the corresponding relation of the humidity value of the load borne in the inner cylinder through electric signals.

After the drying program starts to run, a plurality of first humidity values of the inner drum of the clothes dryer can be obtained at a plurality of different time points in a first preset time. The humidity values may be collected every 500ms, and an average value of all the humidity values collected within 60s is used as a first humidity value at a time point, that is, each different time point may correspond to one first humidity value. The first preset time may be 10 minutes, and then 10 different time points may be provided within 10 minutes, and 10 first humidity values may be acquired at the 10 different time points, although the first preset time may also be specifically set according to an actual situation.

And 102, determining a target load carried in the inner barrel according to the plurality of first humidity values.

After obtaining the plurality of first humidity values, a target load carried in the dryer inner drum can be determined according to the plurality of first humidity values. Specifically, the plurality of first humidity values may be respectively compared with a preset humidity threshold; when the first humidity values are all larger than a preset humidity threshold value, determining that the target load is a common load or a mixed load; when the first humidity values are not all smaller than or equal to the preset temperature threshold value, determining that the target load is a characteristic load; and when the plurality of first humidity values are all smaller than or equal to the preset humidity threshold value, determining that the target load is a special load or an empty cylinder.

The preset humidity threshold value can be correspondingly set according to the corresponding humidity value when the inner barrel is an empty barrel, but the actual value of the preset humidity threshold value is compared with the humidity value of the empty barrel, and the preset humidity threshold value is larger than the humidity value corresponding to the empty barrel. The common load is a load type which is not easy to dry, such as cotton type and the like; the special load can be a load type with part of the load easy to dry and part of the load difficult to dry, such as a quick-drying type or waterproof cloth material on the surface, a cotton type on the inner layer and the like, and the special load can also be a load type with all parts easy to dry, such as a quick-drying type or waterproof cloth material; the hybrid load is a combination of a common load and a special load, namely, the inner cylinder comprises both the common load and the special load; the empty cylinder is the inner cylinder which does not bear the load to be dried.

When the first humidity values are all larger than the preset humidity threshold value, it indicates that the moisture content of the target load in the inner barrel is higher in the first preset time, the drying program of the clothes dryer does not dry the target load in the first preset time, and the target load belongs to a load type which is not easy to dry, that is, the target load is a common load.

When the first humidity values are not all smaller than or equal to the preset humidity threshold value, it is indicated that a part of the moisture content of the target load in the inner cylinder is higher and a part of the moisture content is lower in the first preset time, the drying program of the clothes dryer dries a part of the target load in the first preset time, while a part with the higher moisture content is not dried, the target load belongs to a load type in which a part is easily dried and a part is not easily dried, namely the target load is a characteristic load.

It should be noted that, since the clothes dryer can dry a plurality of loads at the same time, and the types of the plurality of loads may not include a type, for example, the inner drum includes both a normal load and a special load, but the humidity value in the inner drum is always greater than the preset humidity threshold value due to the presence of the normal load in the inner drum, and even if there is a part of the special load which is easily dried, the humidity value of the whole inner drum is not affected, therefore, when the humidity values of the plurality of first loads are greater than the preset humidity threshold value, the target load may be a normal load, or may be a combination of a normal load and a special load, that is, the target load is a mixed load.

When the first humidity values are all smaller than or equal to the preset humidity threshold value, the moisture content of the target load in the inner cylinder is lower in the first preset time, and the target load belongs to a load type with all parts easy to dry, namely the target load is a special load; or the inner barrel does not bear the target load, namely the target load is an empty barrel.

Based on the target load, the remaining operation time of the drying program is determined 103.

After the target load is determined by the plurality of first humidity values detected at the plurality of different time points within the first preset time, a remaining operation time of the drying course may be determined based on the target load.

Specifically, if the target load is a common load or a mixed load, after a first preset time, obtaining a plurality of second humidity values of the inner cylinder at a plurality of different time points within a second preset time; if the second humidity values are all smaller than or equal to the preset humidity threshold value, the running time of the drying program from the beginning to the current moment is obtained; and calculating the residual operation time of the drying program according to the operated time of the drying program, such as calculating the residual operation time of the drying program through a fitting formula.

After the first preset time, the drying program of the clothes dryer is in a continuous working state, so that the humidity value of a target load, namely a common load or a mixed load in the inner cylinder is gradually reduced, when a plurality of second humidity values of the inner cylinder at a plurality of different time points in a second preset time are detected to be smaller than or equal to a preset humidity threshold value, the current water content of the target load is low and tends to a stable state, the residual running time of the drying program can be calculated by obtaining the running time of the drying program, the clothes drying is stopped immediately, the drying program in the clothes dryer is automatically controlled to dry the target load to reach the target water content set by a user, and the user experience is improved. Wherein, the second preset time may be 5 minutes.

It should be noted that after the target load is judged to be a normal load or a special load through a plurality of first humidity values acquired at different time points within a first preset time, a fitting formula can be obtained through fitting according to a large amount of normal load or mixed load test data, and the purpose is to record the running time of all normal loads or mixed loads with different initial water contents, which is dried to a preset humidity threshold value each time, and record the remaining running time required for drying the normal loads or mixed loads to the target water content set by a user, so as to obtain a relation curve between the running time and the remaining running time, and obtain the fitting formula through fitting of a second-order polynomial or a higher-order polynomial or other characteristic equations. The target moisture content set by the user may correspond to a working mode of a drying program of the dryer, such as a semi-dry mode, a standard dry mode or an extra-dry mode, and different fitting formulas are obtained corresponding to different working modes of the drying program.

Specifically, working modes of a drying program are obtained, wherein the working modes comprise a semi-dry mode, a standard dry mode and an extra dry mode; when the working mode is the semi-dry mode, acquiring first running time of the drying program, and calculating first residual running time of the drying program through a first fitting formula based on the first running time; when the working mode is the standard dry mode, acquiring second running time of the drying program, and calculating second residual running time of the drying program through a second fitting formula based on the second running time; and when the working mode is the special dry mode, acquiring third operated time of the drying program, and calculating third residual operated time of the drying program through a third fitting formula based on the third operated time.

In addition, if the target load is the special load, the water content of the special load is already low after the drying process of the first preset time, so that the residual operation time of the drying program does not need to be calculated through a fitting formula, and the residual operation time that a large number of special loads reach the target water content set by the user by adopting a timing drying technology can be recorded, wherein the target water content set by the user can correspond to the working mode of the drying program of the clothes dryer, such as a semi-dry mode, a standard dry mode or a special dry mode, and different working modes of the drying program correspond to different residual operation times. It should be noted that different operation modes of the drying program correspond to the same timing drying time, such as 30 minutes.

If the target load is a special load, obtaining the working mode of a drying program, wherein the working mode comprises a semi-dry mode, a standard dry mode and a special dry mode; when the working mode is the semi-dry mode, taking the sum of the preset fixed time and the first preset time as the fourth residual running time of the drying program; when the working mode is the standard dry mode, taking the sum of the preset fixed time and the second preset time as the fifth residual running time of the drying program; and when the working mode is the extra-dry mode, taking the sum of the preset fixed time length and the third preset time length as a sixth residual running time of the drying program. The target moisture content of the target load dried in the semi-drying mode is higher than that dried in the standard drying mode by the drying program, so that the first preset time length is shorter than the second preset time length; similarly, since the target moisture content of the target load dried in the standard dry mode is higher than the target moisture content dried in the special dry mode by the drying program, the second preset time period is shorter than the third preset time period.

Wherein the preset fixed time is the timing drying time, such as 30 minutes. The first preset time period in the semi-dry mode may be 10 minutes, and the fourth remaining operation time is 40 minutes; the second preset time in the standard dry mode may be 40 minutes, and the fifth remaining operation time is 70 minutes; the third preset time period in the ultradry mode may be 60 minutes, and the sixth remaining operation time is 90 minutes.

If the target load is an empty drum, it indicates that the inner drum does not bear the load, and only the moisture content of the empty drum needs to be dried, so that the seventh residual operation time of the drying program corresponding to the empty drum is a fixed value, for example, 20 minutes, and the purpose of drying the empty drum is to dry the water contained in the empty drum, so that the influence of the residual water in the inner drum on the humidity value of the inner drum measured by next drying is avoided. It should be noted that, if the target load in the inner cylinder is not a special load, but the volume or the surface area of the target load is small, so that the influence on the humidity value of the whole inner cylinder is small, that is, the detected plurality of first humidity values are all smaller than or equal to the preset humidity value. At this time, the target load with the small volume or the small surface area is loaded in the inner cylinder, but the target load is judged to be an empty cylinder through the above mode, so that the target load with the small volume or the small surface area can be dried while the empty cylinder is dried, and the drying requirement is met.

And 104, when the remaining operation time of the drying program is finished, closing the drying program.

After different residual running times of the drying programs corresponding to different target loads are obtained, when the drying programs run to the end of the residual running time, the drying programs are automatically controlled to be closed, so that the clothes drying is stopped immediately, and the requirements that the target loads required to be dried by a user reach different target water contents are met.

As can be seen from the above, in the embodiment, when the drying program of the clothes dryer is started, a plurality of first humidity values of the inner cylinder at a plurality of different time points within a first preset time are obtained; determining a target load carried in the inner barrel according to the plurality of first humidity values; determining a remaining operation time of the drying program based on the target load; when the remaining operation time of the drying process is finished, the drying process is closed. The type of the load is determined according to the humidity value of the inner cylinder of the clothes dryer, and the residual operation time of the drying program of the clothes dryer is determined according to the type of the load, so that the effect of automatically controlling the clothes dryer to stop immediately after the clothes dryer is dried can be achieved, and the user experience is improved.

Referring to fig. 2, fig. 2 is a second flowchart of a control method of a clothes dryer according to an embodiment of the present disclosure. The specific operation steps of the control method of the clothes dryer can be as follows:

201, when a drying program of the clothes dryer is started, acquiring a plurality of first humidity values of the inner barrel at a plurality of different time points in a first preset time.

In this embodiment, a user may touch a physical key or a virtual key and control the dryer to start operating the drying program through a voice instruction, the drying program may be divided into different working modes according to different target moisture contents after the user load finishes drying, such as a semi-dry mode, a standard dry mode, or an extra-dry mode, the target moisture content of the load in the semi-dry mode may be 6% to 10%, the target moisture content of the load in the standard dry mode may be 2% to 5%, and the target moisture content of the load in the extra-dry mode may be 0% to 1%.

It should be noted that, in order to save energy consumption, the drying program of the clothes dryer may have a default operation time, such as 60 minutes, after the drying program is started, and the clothes dryer may control the drying program to be closed after the drying program reaches the default operation time. Certainly, if the moisture content of the load in the inner cylinder is still higher after the drying program reaches the default operation time, the user can also perform the delay operation before the drying program does not reach the default operation time, so that the drying operation can be continued according to the set delay time after the drying program reaches the default operation time, and the moisture content of the load in the inner cylinder can reach the target moisture content satisfied by the user.

After the drying program starts to run, a plurality of first humidity values of the inner drum of the clothes dryer can be obtained at a plurality of different time points in a first preset time. The humidity values may be collected every 500ms, and an average value of all the humidity values collected within 60s is used as a first humidity value at a time point, that is, each different time point may correspond to one first humidity value. The first preset time may be 10 minutes, and then 10 different time points may be provided within 10 minutes, and 10 first humidity values may be acquired corresponding to the 10 different time points, and of course, the first preset time may also be specifically set according to actual conditions.

A target load carried in the inner drum is determined 202 based on the plurality of first humidity values.

After obtaining the plurality of first humidity values, a target load carried in the dryer inner barrel can be determined according to the plurality of first humidity values. Specifically, the plurality of first humidity values may be respectively compared with a preset humidity threshold value, so as to determine that the target load is a normal load, a mixed load, a special load, an empty drum, or the like. When the first humidity values are all larger than a preset humidity threshold value, determining that the target load is a common load or a mixed load; when the first humidity values are not all smaller than or equal to the preset temperature threshold value, determining that the target load is a special load; when the first humidity values are all smaller than or equal to the preset humidity threshold value, the target load is determined to be a special load or an empty drum.

The preset humidity threshold value can be correspondingly set according to the corresponding humidity value when the inner barrel is an empty barrel, but the actual value of the preset humidity threshold value is compared with the humidity value of the empty barrel, and the preset humidity threshold value is larger than the humidity value corresponding to the empty barrel. The common load is a load type which is not easy to dry, such as cotton type and the like; the special load can be a load type with part of the load easy to dry and part of the load difficult to dry, such as a quick-drying type or waterproof cloth material on the surface, a cotton type on the inner layer and the like, and the special load can also be a load type with all parts easy to dry, such as a quick-drying type or waterproof cloth material; the hybrid load is a combination of a common load and a special load, namely the inner cylinder comprises both the common load and the special load; the empty cylinder is the inner cylinder which does not bear the load to be dried.

When the first humidity values are not all less than or equal to the preset humidity threshold value, it is indicated that a part of the moisture content of the target load in the inner cylinder is higher and a part is lower in the first preset time, the drying program of the clothes dryer dries a part of the target load in the first preset time, the part with the higher moisture content is not dried, the target load belongs to a load type that a part of the target load is easy to dry and a part of the target load is difficult to dry, namely the target load is a special load.

It should be noted that, since the clothes dryer can dry a plurality of loads at the same time, and the plurality of loads may not be of a single type, for example, the inner drum contains both a normal load and a special load, however, since the normal load exists in the inner drum, the humidity value in the inner drum is always greater than the preset humidity threshold, even if there is a part of the special load which is easily dried, the humidity value of the whole inner drum will not be affected, therefore, when the plurality of first humidity values are greater than the preset humidity threshold, the target load may be a normal load, or a combination of a normal load and a special load, that is, the target load is a mixed load.

And 203, judging that the target load is a special load or an empty cylinder according to the temperature value.

After the target load is determined to be the special load or the empty cylinder when the first humidity values are all smaller than or equal to the preset humidity threshold value, whether the target load is the special load or the empty cylinder can be judged through the temperature values.

In particular, the inner drum of the dryer may be provided with a temperature sensor, which may be used to detect a temperature value of the inner drum. The temperature sensor can comprise a first temperature sensor and a second temperature sensor, wherein the first temperature sensor can be arranged at the air inlet of the inner barrel and used for detecting a first temperature value of the air inlet of the inner barrel; the second temperature sensor can be arranged at the air outlet of the filter screen side of the clothes dryer and used for detecting a second temperature value of the air outlet.

Obtaining the current temperature value of the inner cylinder of the clothes dryer; judging whether the current temperature value of the inner cylinder is less than or equal to a preset temperature threshold value or not; if yes, determining that the target load is an empty cylinder; and if not, determining that the target load is the special load.

And calculating the difference value between the first temperature value and the second temperature value, and then calculating the absolute value of the difference value as the current temperature value of the inner cylinder. It can be understood that the air inlet and the air outlet of the clothes dryer are two opposite outlets, if a special load exists in the inner cylinder, the temperature detection of the air inlet and the air outlet can be blocked, so that the absolute value of the difference value between the first temperature value and the second temperature value, namely the current temperature value of the inner cylinder, is larger, and the fact that the special load is carried in the inner cylinder but not an empty cylinder is judged.

And 204, when the target load is a common load or a mixed load, calculating the residual running time of the drying program through a fitting formula.

After determining that the target load is the normal load or the hybrid load through a plurality of first humidity values detected at a plurality of different time points within the first preset time, the remaining operation time of the drying course may be determined through a fitting formula.

It should be noted that after the target load is judged to be a normal load or a characteristic load through a plurality of first humidity values acquired at a plurality of different time points within a first preset time, a fitting formula can be obtained through fitting according to a large amount of normal load or mixed load test data, and the purpose is to record the running time of all normal loads or mixed loads with different initial water contents, which is obtained when the normal loads or mixed loads are dried to a preset humidity threshold value each time, and record the remaining running time required for drying the normal loads or mixed loads to the target water content set by a user, so as to obtain a relation curve between the running time and the remaining running time, and obtain the fitting formula through fitting of a second-order polynomial or a higher-order polynomial or other characteristic equations. The target moisture content set by the user may correspond to a working mode of a drying program of the clothes dryer, such as a semi-drying mode, a standard drying mode or an extra-drying mode, and different fitting formulas are obtained corresponding to different working modes of the drying program.

Specifically, working modes of a drying program are obtained, wherein the working modes comprise a semi-dry mode, a standard dry mode and an extra dry mode; when the working mode is the semi-dry mode, acquiring first running time of the drying program, and calculating first residual running time of the drying program through a first fitting formula based on the first running time; when the working mode is the standard dry mode, acquiring second running time of the drying program, and calculating second residual running time of the drying program through a second fitting formula based on the second running time; and when the working mode is the extra-dry mode, acquiring third operated time of the drying program, and calculating third remaining operated time of the drying program through a third fitting formula based on the third operated time.

When the operation mode is the semi-dry mode, and the obtained first elapsed time is T1, the first fitting formula may be T1 ═ a × T1 × T1+ b × T1+ c, where T1 is the first remaining operation time, and a, b, and c are formula coefficients, which may be specifically set according to actual situations, and are not specifically limited herein.

When the working mode is the mark dry mode, the second obtained running time is T2, and the second fitting formula may be T2 ═ a × T2 × T2+ B × T2+ C, where T2 is the second remaining running time, and A, B, C is a formula coefficient, which may be specifically set according to actual conditions, and is not specifically limited herein.

When the working mode is the special dry mode, and the third obtained running time is T3, the third fitting formula may be T3 ═ u × T3 × T3+ v × T3+ w, where T3 is the third remaining running time, and u, v, and w are formula coefficients, which may be specifically set according to actual situations, and are not specifically limited herein.

When the target load is a characteristic load or an empty drum, the remaining operation time of the drying program is determined by a timed drying technique 205.

If the target load is the special load, the water content of the special load is already low after the drying process of the first preset time, so that the residual operation time of the drying program does not need to be calculated through a fitting formula, and the residual operation time for reaching the target water content set by a user through a timing drying technology can be recorded by a large number of special loads, wherein the target water content set by the user can correspond to the working mode of the drying program of the clothes dryer, such as a semi-drying mode, a standard drying mode or a special drying mode, and different working modes of the drying program correspond to different residual operation times. It should be noted that different operation modes of the drying program correspond to the same timing drying time, such as 30 minutes.

If the target load is a special load, obtaining the working mode of a drying program, wherein the working mode comprises a semi-dry mode, a standard dry mode and a special dry mode; when the working mode is the semi-dry mode, taking the sum of the preset fixed time and the first preset time as the fourth residual running time of the drying program; when the working mode is the standard dry mode, taking the sum of the preset fixed time and the second preset time as the fifth residual running time of the drying program; and when the working mode is the special dry mode, taking the sum of the preset fixed time and the third preset time as the sixth residual running time of the drying program. The target moisture content of the target load dried in the semi-dry mode is higher than that of the target load dried in the standard dry mode by the drying program, so that the first preset time length is shorter than the second preset time length; similarly, since the target moisture content of the target load dried in the standard dry mode is higher than the target moisture content dried in the special dry mode by the drying program, the second preset time period is shorter than the third preset time period.

Wherein the preset fixed time is the timing drying time, such as 30 minutes. The first preset duration in the semi-dry mode may be 10 minutes, and the fourth remaining operation time is 40 minutes; the second preset time in the standard dry mode may be 40 minutes, and the fifth remaining operation time is 70 minutes; the third preset time period in the ultradry mode may be 60 minutes, and the sixth remaining operation time is 90 minutes.

If the target load is an empty drum, it indicates that the inner drum does not bear the load, and only the moisture content of the empty drum needs to be dried, so that the seventh remaining operation time of the drying program corresponding to the empty drum is a fixed value, for example, 20 minutes, and the purpose of drying the empty drum is to dry the water contained in the empty drum, so that the influence of the residual water in the inner drum on the humidity value of the inner drum measured in the next drying is avoided. It should be noted that, if the target load in the inner cylinder is not a special load, but the volume or the surface area of the target load is small, so that the influence on the humidity value of the whole inner cylinder is small, that is, the detected plurality of first humidity values are all smaller than or equal to the preset humidity value. At this time, the target load with the small volume or the small surface area is loaded in the inner cylinder, but the target load is judged to be an empty cylinder through the above method, so that the target load with the small volume or the small surface area can be dried while the empty cylinder is dried, and the drying requirement is met.

And 206, when the remaining operation time of the drying course is finished, closing the drying course.

After different residual running times of the drying programs corresponding to different target loads are obtained, when the drying programs run until the residual running time is finished, the drying programs are automatically controlled to be closed, so that the clothes drying can be stopped immediately, and the requirements of the target loads required to be dried by a user on different target water contents are met.

It should be noted that, because the inner drum is in a high temperature state during the drying process of the target load by the drying program of the dryer, and the root cause of the high temperature is the operation of the engine or other functional devices of the dryer, if the dryer is directly turned off after the target load reaches the target moisture content, that is, the drying program is turned off, the engine or other functional devices may be damaged, therefore, after the drying program of the dryer is finished, that is, after the remaining operation time is finished, the dryer may be kept in a neutral position for a certain time, so that the transmitter or other functional devices in the dryer completely stop operating, and then the dryer is turned off, so as to improve the service life of the dryer. The time for holding the neutral gear may be 5 minutes.

In addition, after the user dries the target load to the target moisture content through the clothes dryer, namely the drying program is closed, wrinkles are generated due to the fact that the target load is in a winding state in the inner cylinder in the drying process of the target load, and the clothes dryer can further have a wrinkle preventing function in order to eliminate the wrinkles. Specifically, after the clothes dryer keeps neutral for a certain time, the crease-resistance function of the clothes dryer is started, and after the crease-resistance operation is finished, the clothes dryer is controlled to stop running.

As can be seen from the above, in this embodiment, when a drying program of the dryer is started, a plurality of first humidity values of the inner cylinder at a plurality of different time points within a first preset time are obtained, a target load carried in the inner cylinder is determined according to the plurality of first humidity values, the target load is determined to be a special load or an empty cylinder according to a temperature value, when the target load is a normal load or a mixed load, a remaining operation time of the drying program is calculated by a fitting formula, when the target load is the special load or the empty cylinder, a remaining operation time of the drying program is determined by a timing drying technology, and when the remaining operation time of the drying program is ended, the drying program is closed. The embodiment determines the type of the load through the humidity value and the temperature value of the inner cylinder of the clothes dryer, determines the residual running time of the drying program through the type of the load, can realize the effect of automatically controlling the clothes dryer to stop immediately after the clothes dryer is dried, and further improves the user experience through increasing the crease-resistance function of the target load.
