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 creative effort, shall fall within the protection scope of the present application.

In recent years, the demand of the clothes dryer adopting the heat pump technology on the domestic market is gradually increased, and the sales volume is on the trend of increasing year by year. However, the 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 to cause damage to the clothes and waste 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 device 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, or a condensing type dryer, etc. 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, obtaining the material of the target load carried in the inner cylinder.

In this embodiment, when a user wants to dry clothes using the clothes dryer, the user can first identify the material of the clothes to be dried, wherein the material of the clothes may include hemp, leather, terylene, wool, silk, cotton cloth, wool fabric, silk, acrylic, silk, down, and the like. The clothes to be dried can be identified in various ways, for example, a code scanning gun can be arranged in an inner drum of the clothes dryer, and the material can be identified by scanning a tag or label of the clothes to be dried; for example, a camera can be arranged in the inner cylinder, and corresponding materials are matched from a database through a shot picture; for another example, the user may scan a tag or label of the laundry to be dried through a camera of the electronic device, or may take a picture of the laundry to be dried through the camera of the electronic device to identify the material of the laundry, and the specific identification manner is not limited in this respect.

The clothes to be dried are placed in the inner cylinder of the clothes dryer, so that the load borne by the clothes dryer can be obtained, and after the material of the clothes to be dried is identified, the material of the target load borne by the inner cylinder can be obtained.

And 102, acquiring the temperature change rate of the air outlet of the inner barrel within the preset time after the drying program of the clothes dryer is started.

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.

It should be noted that the target load carried in the inner cylinder may be made of a common load with a high water content or a special load with a low water content, wherein the down material, the wool material and the silk material may be used as special loads, and the cotton material may be used as a common load. Because the special load is influenced by fabric density and the like, misjudgment easily occurs to the bimetallic strip sensing device and the like, so the embodiment explains by down materials, wool materials, real silk materials and the like to achieve the effect of classifying and accurately drying the special load made of different materials.

Specifically, the user can open the drying program through touch control physical key or virtual key to and through voice command control dryer, the drying program of dryer can include a plurality of drying programs to the material of the target load of different materials, if the eiderdown material corresponds to eiderdown drying program, the wool material corresponds to wool drying program, the silk material corresponds to silk drying program. Of course, the clothes to be dried can also be divided into soft type materials, stiff and comfortable type materials, glossy type materials, heavy and thick type materials and transparent type materials.

The drying program corresponding to each material may include different working modes, and may be divided into a semi-drying mode, a standard drying mode, or an extra drying mode according to a difference in target moisture content after the drying program corresponding to the material of the target load is completed, where the target moisture content of the load in the semi-drying mode may be 6% to 10%, the target moisture content of the load in the standard drying mode may be 2% to 5%, and the target moisture content of the load in the extra drying 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 material of the target load in the inner cylinder does not meet the requirement of the user 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 program can continue to perform the drying operation according to the set delay time after reaching the default operation time, and the material of the target load in the inner cylinder can meet the target moisture content.

After the drying program of the clothes dryer is started, the temperature change rate of the air outlet of the inner barrel in the preset time can be obtained. Specifically, after a drying program of the clothes dryer is started, the rotating speed of a compressor of the clothes dryer can be rapidly increased from zero to an initial working rotating speed, the compressor can generate a large amount of heat when working at the initial working rotating speed, the heat is cooled through a condenser, the residual heat is transferred to an air inlet of an inner barrel, the heat is transferred to an accommodating space of the inner barrel from the air inlet of the inner barrel, and the material of a target load borne by the inner barrel is dried.

Because compressor work can continuously produce the heat, consequently, for the material that prevents the target load of continuous heat in to the inner tube from leading to the fact the damage, need set up the air outlet heat extraction at the inner tube, because the material of target load contains moisture, can absorb into the partly heat that the wind gap got into in the inner tube, so the temperature that reachs the air outlet can reduce, also can understand that the material of target load can exert an influence to the temperature of air outlet, and the temperature of inner tube air outlet constantly changes along with the change of the moisture content of the material of target load promptly. The material of the target load has initial moisture content, namely initial weight, and the weight of the material of the target load is continuously reduced along with the continuous reduction of the moisture content, namely the moisture absorbed by the material of the target load is continuously reduced, so that the effect of drying the material of the target load is achieved, the water absorption of the material of the target load is reduced, the capability of absorbing the temperature of the air inlet is reduced, the temperature of the air outlet is continuously increased, namely the weight of the material of the target load and the temperature of the air outlet are in an inverse proportion relation, and the weight of the material of the target load can be represented according to the temperature change rate of the air outlet.

Specifically, the compressor can be controlled to keep working at the initial working rotating speed for a preset time; acquiring a plurality of temperature values of an air outlet of the inner barrel at different time points within preset time; and calculating the temperature change rate of the air outlet according to a plurality of temperature values of the air outlet, wherein positive correlation exists between different time points and a plurality of temperature values corresponding to different time points. The preset time may be 10 minutes, 15 minutes, etc., and is not particularly limited thereto. It should be further noted that the increase of the rotation speed of the compressor from zero to the initial operating rotation speed may take about 2 minutes, and the preset time for acquiring the plurality of temperature values of the air outlet may be 10 minutes from 2 minutes to 12 minutes after the drying program is started.

It should be noted that the calculation of the temperature change rate of the air outlet is only for the purpose of subsequently calculating the remaining operation time of the drying program, and does not indicate that the compressor always operates at the initial operating speed under the drying program, and after the temperature change rate of the air outlet is obtained, the rotating speed of the compressor continues to be increased, so that the temperature of the air inlet of the inner cylinder continues to be increased, and the drying efficiency of the material of the target load is improved. The drying program is still in the rapid heating stage, and then the compressor can keep the maximum working speed to continuously work until the drying program is finished, namely the stable drying stage of the drying program. The rapid heating stage comprises the processes of raising the compressor from zero to the initial working speed and raising the compressor from the initial working speed to the maximum working speed, so that the time of the rapid heating stage is more than 2 minutes for raising the compressor from zero to the initial working speed, and the time for keeping the initial working speed to calculate the air inlet temperature change rate is 10 minutes, and because the heating time is required for the compressor from the initial working speed to the maximum working speed, the time of the rapid heating stage can be 20 minutes.

The residual operation time of the drying program calculated through the temperature change rate of the air outlet comprises a rapid heating stage corresponding to the compressor from the initial working rotating speed to the target working rotating speed and a stable drying stage corresponding to the target working rotating speed.

Because the working temperatures of the drying programs needed by different materials corresponding to the target load are different, the different working temperatures correspond to the maximum working rotating speeds of different compressors. Specifically, according to the material of the target load, determining a target working rotating speed of the compressor corresponding to the material of the target load, wherein the target working rotating speed is greater than the initial working rotating speed, and the target working rotating speed is the maximum working rotating speed of the compressor; and determining a target temperature threshold value of the air inlet of the inner barrel corresponding to the material of the target load according to the target working rotating speed.

The target temperature threshold corresponds to a maximum temperature value of an air inlet of the inner barrel, which is transmitted to the compressor when the compressor works at the target working speed, and if the target temperature threshold is exceeded, a target load in the inner barrel risks being damaged. For example, the target temperature threshold for down feather loading may be 60 ℃, the target temperature threshold for wool loading may be 42 ℃, and the target temperature threshold for silk loading may be 50 ℃.

And 103, calculating the residual operation time of the drying program according to the material of the target load and the temperature change rate of the air outlet.

After the target temperature threshold corresponding to the material of the target load is determined, the remaining operation time of the drying program can be calculated according to different materials of the target load and the temperature change rate of the air outlet.

The calculation formula of the remaining operation time T may be T ═ c × k + b, where c and b are constants, and k is the temperature change rate of the air outlet. It should be noted that, when the drying procedure is in the stable drying stage, that is, the compressor works at the target working rotation speed, the moisture content of the material of the target load in the inner cylinder will gradually decrease, and the temperature of the air outlet of the inner cylinder will continuously increase, so the temperature change rate k of the air outlet will gradually increase, and the continuous consumption of the remaining operation time will continuously decrease, so c is a negative number.

The target load materials of different materials correspond to different formulas with different c and b, so the calculated residual operation time of the target load materials of different materials is also different.

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

After the drying program running time is obtained through calculation, when the drying program runs to the end of the residual running time, the drying program is automatically controlled to be closed, and therefore the clothes dryer is intelligently controlled to achieve the effect that the clothes dryer stops immediately after being dried.

As can be seen from the above, in the embodiment, the material of the target load carried in the inner cylinder is obtained; when a drying program of the clothes dryer is started, acquiring the temperature change rate of an air outlet of the inner cylinder within preset time; calculating the residual operation time of the drying program according to the material of the target load and the temperature change rate of the air outlet; when the remaining operation time of the drying course is finished, the drying course is closed. The embodiment aims at different materials bearing target loads in the inner barrel, the residual operation time of the drying program of the clothes dryer is calculated by detecting the temperature change rate of the air outlet of the inner barrel, the intelligent drying effect of the clothes dryer with accurate classification 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:

and 201, obtaining the material of the target load carried in the inner cylinder.

In this embodiment, when a user wants to dry clothes using the clothes dryer, the user can first identify the material of the clothes to be dried, wherein the material of the clothes may include hemp, leather, terylene, wool, silk, cotton cloth, wool fabric, silk, acrylic, silk, down, and the like. The clothes to be dried can be identified in various ways, for example, a code scanning gun can be arranged in an inner drum of the clothes dryer, and the material can be identified by scanning a tag or label of the clothes to be dried; for example, a camera can be arranged in the inner cylinder, and corresponding materials are matched from a database through a shot picture; for another example, the material of the laundry to be dried is identified by scanning a tag or label of the laundry to be dried through a camera of the electronic device of the user, or by taking a picture of the laundry to be dried through the camera of the electronic device, and the specific identification manner is not specifically limited herein.

202, after the drying program of the clothes dryer is started, acquiring the temperature change rate of the air outlet of the inner cylinder within the preset time.

Specifically, the user can touch the physical key or the virtual key and control the clothes dryer to start the drying program through the voice instruction, the drying program of the clothes dryer can comprise a plurality of drying programs aiming at the target load materials of different materials, and if the down material corresponds to the down drying program, the wool material corresponds to the wool drying program, and the real silk material corresponds to the real silk drying program. Of course, the clothes to be dried can also be divided into soft type materials, stiff and comfortable type materials, glossy type materials, heavy and thick type materials and transparent type materials.

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 target load material in the inner cylinder does not meet the requirement of the user 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 program can continue to perform the drying operation according to the set delay time after reaching the default operation time, and the target load material in the inner cylinder can meet the target moisture content.

When the drying program of the clothes dryer is started, the temperature change rate of the air outlet of the inner barrel in the preset time can be obtained. The compressor can be controlled to keep the initial working rotating speed for working for a preset time; acquiring a plurality of temperature values of an air outlet of the inner barrel at different time points within preset time; and calculating the temperature change rate of the air outlet according to a plurality of temperature values of the air outlet, wherein positive correlation exists between different time points and a plurality of temperature values corresponding to different time points. The preset time may be 10 minutes, 15 minutes, etc., and is not particularly limited thereto. It should be further noted that the increase of the rotation speed of the compressor from zero to the initial operating rotation speed may take about 2 minutes, and the preset time for acquiring the plurality of temperature values of the air outlet may be 10 minutes from 2 minutes to 12 minutes after the drying program is started.

And 203, determining a target temperature threshold value of the air inlet of the inner barrel corresponding to the material of the target load according to the material of the target load.

It should be noted that the calculation of the temperature change rate of the air outlet is only for the purpose of subsequently calculating the remaining operation time of the drying program, and does not indicate that the compressor always operates at the initial operating speed under the drying program, and after the temperature change rate of the air outlet is obtained, the rotating speed of the compressor continues to be increased, so that the temperature of the air inlet of the inner cylinder continues to be increased, and the drying efficiency of the material of the target load is improved. The drying program is still in the rapid heating stage, and then the compressor can keep the maximum working speed to continuously work until the drying program is finished, namely the stable drying stage of the drying program. The rapid heating-up stage comprises the processes of raising the compressor from zero to the initial working speed and raising the compressor from the initial working speed to the maximum working speed, so that the time of the rapid heating-up stage is more than 2 minutes for raising the compressor from zero to the initial working speed, the initial working speed is kept, and the temperature change rate of the air port is calculated for 10 minutes.

The residual operation time of the drying program calculated through the temperature change rate of the air outlet comprises a rapid heating-up stage corresponding to the compressor from the initial working rotating speed to the target working rotating speed and a stable drying stage corresponding to the target working rotating speed.

And 204, calculating the residual operation time of the drying program according to the material of the target load and the temperature change rate of the air outlet.

The calculation formula of the remaining operation time T may be T ═ c × k + b, where c and b are constants, and k is the temperature change rate of the air outlet. It should be noted that, when the drying procedure is in the stable drying stage, that is, the compressor is working at the target working speed, the moisture content of the material of the target load in the inner cylinder will gradually decrease, and the temperature of the air outlet of the inner cylinder will continuously increase, so the temperature change rate k of the air outlet will gradually increase, and the continuous consumption of the remaining operation time will continuously decrease, so c is a negative number.

The formula c and b corresponding to the target load material of different materials are different, and therefore, the calculated residual operation time of the target load material of different materials is also different.

Specifically, when the material of the target load is a first material, calculating a first residual operation time of the drying program according to the first material and the temperature change rate; when the target load is made of a second material, calculating a second residual operation time of the drying program according to the second material and the temperature change rate; when the target load is made of a third material, calculating a third residual operation time of the drying program according to the third material and the temperature change rate; the high-temperature resistant degree of the first material is smaller than that of the second material, and the high-temperature resistant degree of the second material is smaller than that of the third material.

The first material may be a wool material, and the formula of the first remaining operation time T1 corresponding to the wool material may be T1 ═ c1 × k + b 1; the second material may be a real silk material, and a formula of the second remaining operation time T2 corresponding to the real silk material may be T2 ═ c2 × k + b 2; the third material may be a down material, and a formula of the third remaining operating time T3 corresponding to the down material may be T3 ═ c3 × k + b3, where c1, c2, and c3, b1, b2, and b3 are set according to different respective materials, that is, c1, c2, and c3, b1, b2, and b3 may be the same or different, and are not limited specifically herein.

In addition, if the target load is made of a first material, the compressor is controlled to work at a first target working rotating speed for a first residual operation time, and in the first residual operation time, the temperature of the air inlet of the inner barrel does not exceed a first target temperature threshold; if the target load is made of a second material, controlling the compressor to work at a second target working speed for a second residual operation time, and controlling the temperature of the air inlet of the inner barrel not to exceed a second target temperature threshold value in the second residual operation time; if the target load is made of a third material, controlling the compressor to work at a third target working rotating speed for a third residual running time, and controlling the temperature of the air inlet of the inner barrel not to exceed a third target temperature threshold value in the third residual running time; wherein the first target temperature threshold is less than the second target temperature threshold, and the second target temperature threshold is less than the third target temperature threshold.

The target working rotating speeds of the compressors corresponding to the first material, the second material and the third material are different, the target working rotating speeds of the compressors corresponding to the first material, the second material and the third material are corresponding to a target temperature threshold of an air inlet of the inner cylinder, and if the temperature in the inner cylinder exceeds the target temperature threshold, the target load can be damaged.

It should be noted that, because the high temperature resistance degree of the wool material is less than that of the real silk material, the first target temperature threshold corresponding to the wool material is less than the second target temperature threshold corresponding to the real silk material; the high temperature resistant degree of the real silk material is less than that of the down feather material, so that the second target temperature threshold value corresponding to the real silk material is less than the third target temperature threshold value corresponding to the down feather material.

It should be further noted that, since the wool material itself is wound by heat, the target load of the wool material may be wrinkled after being dried, which may affect the dressing effect of the user. Therefore, in order to avoid the winding, the rotating speed of the inner cylinder can be controlled not to be lower than the preset rotating speed threshold value in the process of drying the first material of the wool material, so that the first material can be kept in the attaching operation state on the same scale of the inner cylinder to operate for the first residual operation time. Thereby guarantee after first remaining time, the first material of wool material can reach the effect of wearing promptly or receiving promptly.

In addition, a user may dry loads of different materials at the same time in a drying process using the dryer. Such as drying wool and down, or wool and silk, etc. Specifically, if the target load is a mixed load of a first material and a second material, the compressor is controlled to operate at a first target operating speed for the first remaining operation time, and the temperature of the air inlet of the inner cylinder does not exceed a first target temperature threshold value within the first remaining operation time; if the target load is made of a mixed load of a second material and a third material, controlling the compressor to work at a second target working speed for the second residual running time, wherein the temperature of the air inlet of the inner cylinder does not exceed a second target temperature threshold value in the second residual running time; if the target load is a mixed load of a first material and a third material, controlling the compressor to work at a first target working speed for the first residual running time, wherein the temperature of the air inlet of the inner barrel does not exceed a first target temperature threshold value in the first residual running time; wherein the first target temperature threshold is less than the second target temperature threshold.

It can be understood that if the first material is wool material, the second material is real silk material, the high temperature resistant degree of wool material is that the target temperature threshold value of the air inlet of the inner barrel is not more than 42 ℃, and the target temperature threshold value corresponding to real silk material is not more than 50 ℃, if the material of the target load in the inner barrel comprises the mixed load of wool material and real silk material, then the damage of the wool material caused by overhigh temperature can not be received in the drying process, therefore, the compressor can work for the first residual operation time at the first target working rotation speed, so as to enable the first target temperature threshold value of the air outlet.

205, calculating the remaining operation time of the drying program according to the operation mode of the drying program, the material of the target load and the temperature change rate of the air outlet.

In some embodiments, the drying procedure for target load materials of different materials may be divided into different operation modes, such as a semi-drying mode, a standard drying mode and an extra-drying mode, in order to meet the requirements of users for different target moisture contents.

Therefore, the operation modes of the drying program can be obtained, and the operation modes include a semi-drying mode, a standard drying mode and an extra-drying mode; when the working mode is the semi-dry mode, calculating fourth residual operation time of the drying program according to the material of the target load and the temperature change rate of the air outlet; when the working mode is a standard dry working mode, calculating fifth residual running time of the drying program according to the material of the target load and the temperature change rate of the air outlet; and when the working mode is an extra-dry working mode, calculating sixth residual running time of the drying program according to the material of the target load and the temperature change rate of the air outlet, wherein the fourth residual running time is less than the fifth residual running time, and the fifth residual running time is less than the sixth residual running time.

Different residual operation times under different working modes enable target loads made of different materials to reach different water contents, and different requirements of users can be met.

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

After the drying program running time is obtained through calculation, when the drying program runs to the end of the residual running time, the drying program is automatically controlled to be closed, so that the clothes dryer is intelligently controlled to achieve the effect of stopping the clothes drying immediately, and the requirements that the target load required by a user to be dried achieves different target water contents are met.

It should be noted that, because the inner cylinder is in a high temperature state during the drying process of the drying program of the dryer to the target load, 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, after 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 state 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, thereby prolonging the service life of the dryer. The time for keeping the neutral gear can be 5 minutes, and the process can be regarded as a cooling stage.

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, the present embodiment obtains the material of the target load carried in the inner cylinder; when a drying program of the clothes dryer is started, acquiring the temperature change rate of an air outlet of the inner cylinder within preset time; determining a target temperature threshold value of an air inlet of the inner barrel corresponding to the material of the target load according to the material of the target load; calculating the residual operation time of the drying program according to the material of the target load and the temperature change rate of the air outlet; when the remaining operation time of the drying course is finished, the drying course is closed. The embodiment aims at different materials bearing target loads in the inner barrel, the residual operation time of the drying program of the clothes dryer is calculated by detecting the temperature change rate of the air outlet of the inner barrel, the intelligent drying effect of the clothes dryer with accurate classification can be achieved, and the user experience is improved.
