The method provided by the embodiment of the application can be realized through a computer program, and when the computer program is executed, each step in the drying control method provided by the embodiment of the application is completed. In some embodiments, the computer program may be executed by a processor in the drying control apparatus. Fig. 1 is a schematic flow chart of an implementation of a drying control method provided in an embodiment of the present application, and as shown in fig. 1, the drying control method includes the following steps:
step S101, determining to enter a dehydration stage, and controlling a compressor to operate at a first frequency to generate hot air.
The heat pump clothes dryer utilizes a heat pump system to absorb heat from the surrounding environment and transfer the heat to an object to be dried (such as clothes and the like), the working principle of the heat pump clothes dryer is opposite to that of a refrigerator, and the heat pump clothes dryer works according to the reverse Carnot cycle principle, except that the clothes dryer is at a raised temperature, and a refrigerant is at a lowered temperature. In the embodiment of the application, the clothes treatment device refers in particular to a frequency conversion clothes treatment device which realizes internal heat transfer through a heat pump system, such as a heat pump clothes dryer and a heat pump washing and drying integrated machine. Correspondingly, the object to be dried is the clothes to be dried. The following description will be given by taking a heat pump dryer as an example, and the following dryers are all specifically referred to as heat pump dryers without specific designation.
The heat pump clothes dryer comprises a heat pump system, wherein the heat pump system comprises an evaporator, a condenser, a compressor and a throttling device (such as a capillary tube and the like). The inlet of the throttling device is communicated with the outlet of the condenser, and the outlet of the throttling device is communicated with the inlet of the evaporator, namely, the condenser and the evaporator are communicated through the throttling device. The inlet of the condenser is communicated with the exhaust pipe of the compressor, the outlet of the evaporator is communicated with the intake pipe of the compressor, a refrigerant circulating path of the compressor → the condenser → the throttling device → the evaporator → the compressor is formed, the refrigerant is compressed into high-temperature high-pressure gaseous refrigerant in the compressor, the high-temperature high-pressure gaseous refrigerant is discharged out of the compressor through the exhaust port of the compressor and then enters the condenser to be condensed and release heat, the high-temperature high-pressure gaseous refrigerant is gradually changed into high-pressure liquid refrigerant, the high-pressure liquid refrigerant flows out of the condenser and enters the throttling device to be throttled, cooled and depressurized, the high-pressure liquid refrigerant is changed into low-temperature low-pressure gas-liquid mixed refrigerant, then the low-temperature low-pressure refrigerant flows out of the throttling device and enters the evaporator to absorb heat in the surrounding environment to be continuously evaporated and changed into low-pressure gaseous refrigerant, the low-pressure gaseous refrigerant flows out of the evaporator and then reenters the compressor for compression through the air inlet of the compressor, and the cycle is repeated.
The compressor is used as the power of the refrigeration cycle, plays a decisive role in the whole drying process, and the operation of the compressor can enable the condenser to generate hot air to provide a heat source for the barrel.
A drying control apparatus of a dryer controls a compressor of the dryer to operate at a first frequency after entering a dehydration stage. In the embodiment of the present application, the value of the first frequency may be any value between 30Hz (hertz) and 100Hz, for example, 60 Hz.
And S102, controlling a fan to operate at a first rotating speed, and introducing the hot air into a barrel of the clothes treatment device.
The drying control device controls the fan to start to operate at a first rotating speed to drive the impeller to rotate, and hot air is introduced into the barrel of the clothes treatment device. In the embodiment of the present application, the value of the first rotation speed may be any value between 1000r/min (revolutions per minute) and 6000r/min, for example 2000 r/min.
In the embodiment of the application, drying control equipment controls the compressor and the fan to operate simultaneously after determining to dewater, so that the temperature in the barrel body can reach the drying temperature quickly, and the clothes can be dried quickly, thereby shortening the drying time, reducing the energy consumption and realizing energy conservation.
The drying control method provided by the embodiment of the application is applied to a clothes treatment device, and the method comprises the following steps: determining to enter a dehydration stage, and controlling a compressor to operate at a first frequency to generate hot air; the control fan runs at a first rotating speed, hot air is introduced into the barrel of the clothes treatment device to pre-dry the objects to be dried in the barrel, and the temperature in the barrel can be rapidly raised by controlling the compressor and the fan to run simultaneously, so that bedding is made in a main drying stage. Therefore, the time of the whole drying process can be shortened, the energy consumption can be reduced, and the energy conservation is realized.
On the basis of the embodiment shown in fig. 1, an embodiment of the present application further provides a drying control method, fig. 2 is a schematic view of another implementation flow of the drying control method provided in the embodiment of the present application, and as shown in fig. 2, the drying control method includes the following steps:
step S201, determining to enter a dehydration stage, controlling the compressor to operate at a first frequency to generate hot air.
A drying control apparatus of a dryer controls a compressor of the dryer to operate at a first frequency after entering a dehydration stage. The first frequency here may be a relatively high frequency, and the high frequency of the compressor may promote the generation of hot air, thereby increasing the temperature rise rate. In the embodiment of the present application, the value of the first frequency may be any value between 50Hz (hertz) and 100Hz, for example, 60 Hz.
And S202, controlling a fan to operate at a first rotating speed, and introducing the hot air into a barrel of the clothes treatment device.
The drying control device controls the fan to start to operate at a first rotating speed to drive the impeller to rotate, and hot air is introduced into the barrel of the clothes treatment device. The rotating speed of the fan can be relatively low, the generated hot air temperature is guaranteed not to be affected by the fan, and under the normal condition, if the rotating speed of the fan is high, the hot air temperature can be reduced, so that the first rotating speed is relatively low. In the embodiment of the present application, the value of the first rotation speed may be any value between 1000r/min (revolutions per minute) and 2500r/min, for example 2000 r/min.
In the embodiment of the application, after getting into the dehydration stage, the control compressor moves with high frequency to control fan moves with low-speed, in order when the temperature is lower in the staving, let in the hot-air of less amount of wind in to the staving, so can make the temperature of compressor blast pipe, the temperature of condenser export and the temperature of staving air inlet can rise the setting value fast, thereby rise the temperature in the dryer staving as early as possible, make the temperature in the staving reach drying temperature fast.
Step S203, detecting a temperature inside the laundry treating apparatus.
Here, the temperature inside the dryer is detected, and at least one of the temperature of the air inlet of the tub of the dryer, the temperature of the air outlet of the tub, the temperature of the compressor discharge pipe, and the temperature of the condenser outlet may be detected.
Step S204, determining that the temperature in the clothes treatment device meets a first preset condition, and controlling the compressor to operate at a second frequency.
Here, the second frequency is smaller than the first frequency.
After the temperature in the clothes dryer is detected, whether the detected temperature meets a first preset condition is judged. Here, the first preset condition is used to determine whether the temperature in the tub of the dryer rises to a set drying temperature. In some embodiments, whether the temperature inside the dryer rises to the drying temperature may be determined according to at least one of a temperature of the compressor discharge pipe, a temperature of the condenser outlet, and a temperature of the tub air inlet. When the temperature in the clothes dryer rises to the drying temperature, the temperature in the clothes dryer is determined to meet a first preset condition, the temperature in the barrel body reaches the drying temperature, the operation frequency of the compressor is reduced to a second frequency, the drying energy consumption of the clothes dryer can be reduced, and therefore energy conservation is achieved. Here, the second frequency may take any value between 30Hz and 50Hz, for example 40 Hz.
And S205, controlling the fan to operate at a second rotating speed.
Here, the second rotation speed is greater than the first rotation speed. In the embodiment of the application, the value of the second rotating speed can be any value between 2500r/min and 6000r/min, such as 5000 r/min.
When the temperature in the clothes dryer meets a first preset condition, the temperature in the barrel body reaches the pre-drying temperature, at the moment, in order to accelerate the drying speed, the drying time is shortened, the rotating speed of the fan is increased from the first rotating speed to the second rotating speed, hot air with larger air quantity is introduced into the barrel body by improving the rotating speed of the fan, so that the moisture on the clothes to be dried can be quickly evaporated into steam, the clothes are dried as soon as possible, and the drying time is greatly shortened.
In the embodiment of the application, when the dehydration stage is started, the drying control equipment can enable the temperature in the barrel body to quickly reach the pre-drying temperature by controlling the high-frequency operation of the compressor and the low-speed rotation of the fan; when the temperature in the barrel body reaches the pre-drying temperature, the low-frequency operation of the compressor and the high-speed rotation of the fan are controlled, so that the temperature in the barrel body can reach the drying temperature quickly, the energy consumption is reduced while clothes are dried quickly, the energy conservation is realized, and the problems of long drying time and high energy consumption of the heat pump clothes dryer are solved.
The drying control method provided by the embodiment of the application is applied to a clothes treatment device, and the method comprises the following steps: determining to enter a dehydration stage, and controlling a compressor to operate at a first frequency to generate hot air; controlling a fan to operate at a first rotating speed, and introducing the hot air into a barrel body of the clothes treatment device; detecting a temperature within the laundry treating apparatus; determining that the temperature in the laundry treating device satisfies a first preset condition, and controlling the compressor to operate at a second frequency, which is less than the first frequency; and controlling the fan to operate at a second rotating speed, wherein the second rotating speed is greater than the first rotating speed. The hot air is introduced into the barrel body of the clothes treatment device to pre-dry the objects to be dried in the barrel body, and the temperature in the barrel body can be rapidly raised by controlling the compressor and the fan to operate simultaneously, so that the hot air is used for bedding in a main drying stage. When the temperature in the barrel body is low, the drying control equipment can enable the temperature in the barrel body to quickly reach the drying temperature by controlling the compressor to operate at high frequency and the fan to rotate at low speed; after the temperature in the barrel body reaches the drying temperature, the compressor is controlled to operate at a low frequency, the fan is controlled to rotate at a high speed, the drying time can be shortened, the energy consumption is reduced while clothes are dried quickly, and energy conservation is achieved.
In some embodiments, the dehydration stage in the above embodiments is included in the drying stage or is a separate dehydration stage.
The dehydration stage is included in the drying stage, that is, when entering the drying stage, the laundry to be dried in the tub is not dehydrated yet or is dehydrated already, but the dehydration is not complete, and the moisture content of the laundry to be dried is still relatively large. At this moment, after entering the drying stage, the drying stage is firstly entered to execute the dehydration procedure, and the pre-drying is carried out while executing the dehydration procedure, so that the temperature in the barrel body can be quickly raised to the drying temperature, and the time length of the whole drying process can be shortened.
The dehydration stage is a separate dehydration stage, namely, when the drying stage is started, the clothes to be dried in the barrel body are dehydrated and are completely dehydrated. Performing a dehydration program in a dehydration stage and pre-drying clothes to be dried; the drying stage is entered after the dehydration stage is completed, and after the drying stage is entered through pre-drying, the temperature in the barrel body can be quickly raised to the drying temperature, so that the duration of the whole drying process can be shortened.
In some embodiments, the drying control apparatus may determine whether the temperature inside the dryer satisfies the first preset condition by the temperature of the hot air entering the tub, and the step S203 "detecting the temperature inside the laundry treating device" in the embodiment shown in fig. 2 may be implemented as the following steps:
in step S203a1, the temperature of the inlet of the tub is detected to obtain a first temperature.
Here, the temperature of the tub air inlet, that is, the temperature of the hot air of high drying temperature entering the tub of the dryer is detected.
In the embodiment of the application, the temperature of the air entering the barrel of the clothes dryer can be detected through a temperature sensor, and the temperature sensor is arranged at the air inlet of the barrel of the clothes dryer.
At this time, "determining that the temperature inside the laundry treating apparatus satisfies the first preset condition" in step S204 of the embodiment shown in fig. 2 may be implemented as the following steps:
step S204a1, determining whether the first temperature reaches a first temperature threshold.
After detecting the first temperature, the drying control device judges whether the first temperature reaches a first temperature threshold value. When the first temperature reaches a first temperature threshold value, namely the first temperature is greater than the first temperature threshold value, determining that the temperature in the barrel of the clothes dryer meets a first preset condition, and continuing to execute the step S204; when the first temperature does not reach the first temperature threshold, that is, the first temperature is less than or equal to the first temperature threshold, it is determined that the temperature in the dryer tub does not meet the first preset condition, and at this time, the operation returns to step S201 to control the compressor to continue to operate at the first frequency.
In some embodiments, the drying control device may also determine whether the temperature in the dryer satisfies the first preset condition by the temperature of the exhaust pipe of the compressor, and at this time, step S203 "detecting the temperature in the laundry treating apparatus" in the embodiment shown in fig. 2 may be implemented as the following steps:
step S203b1, detecting the temperature of the compressor discharge pipe to obtain a second temperature.
Here, the temperature of the compressor discharge pipe, that is, the temperature of the hot air of the high drying temperature discharged from the compressor is detected.
In the embodiment of the present application, the temperature of the air discharged from the compressor may be detected by a temperature sensor provided at an outlet of an exhaust pipe of the dryer compressor.
At this time, "determining that the temperature inside the laundry treating apparatus satisfies the first preset condition" in step S204 of the embodiment shown in fig. 2 may be implemented as the following steps:
step S204b1, determining whether the second temperature reaches a second temperature threshold.
After detecting the second temperature, the drying control device determines whether the second temperature reaches a second temperature threshold. When the second temperature reaches a second temperature threshold value, namely the second temperature is greater than the second temperature threshold value, determining that the temperature in the dryer barrel meets a first preset condition, and continuing to execute the step S204; when the second temperature does not reach the second temperature threshold, that is, the second temperature is less than or equal to the second temperature threshold, it is determined that the temperature in the tub of the dryer does not meet the first preset condition, and then the operation returns to step S201 to control the compressor to continue to operate at the first frequency.
In some embodiments, the drying control device may also determine whether the temperature in the dryer satisfies the first preset condition by the temperature at the outlet of the condenser of the dryer, and at this time step S203 "detecting the temperature in the laundry processing apparatus" in the embodiment shown in fig. 2, may be implemented as the following steps:
step S203c1, detecting a temperature of the laundry treating device condenser outlet to obtain a third temperature.
Here, the temperature of the outlet of the condenser, that is, the temperature of the hot air of the dry high temperature condensed by the condenser is detected.
In the embodiment of the application, the temperature of the outlet of the condenser can be detected through a temperature sensor, and the temperature sensor is arranged at the outlet of the condenser of the clothes dryer.
At this time, "determining that the temperature inside the laundry treating apparatus satisfies the first preset condition" in step S204 of the embodiment shown in fig. 2 may be implemented as the following steps:

Fig. 5 is a schematic flow chart of another implementation of the drying control method provided in the embodiment of the present application, and as shown in fig. 5, the method includes the following steps:
step S501, a drying program is started.
Step S502, a dehydration program is started, the compressor is controlled to operate at a first frequency, and the fan operates at a first rotating speed.
When the drying program is started, the compressor starts to operate at a first frequency, the fan starts to operate at a first rotating speed, wherein the first frequency is high frequency (such as 50-100 Hz), the first rotating speed is low rotating speed (such as 1000-2500 r/min), the compressor operates at a high frequency, the fan operates at a low rotating speed, a small air volume is kept, at the same time, the dehydration operation starts, the dehydration program is performed according to a normal program, namely, the dehydration and heat pump systems and the fan operate simultaneously, and the temperature in the barrel body can quickly rise to a set value through such logic.
In step S503, it is determined whether the temperature T1 of the air inlet of the tub reaches a set value T1, the temperature T2 of the compressor discharge pipe reaches a set value T2, and the temperature T3 of the condenser outlet reaches a set value T3.
In the embodiment of the present application, the air inlet temperature sensor 401 may be used to detect the temperature t1 of the air inlet of the barrel, the compressor exhaust pipe temperature sensor 402 may be used to detect the temperature t2 of the compressor exhaust pipe, and the condenser outlet temperature sensor 404 may be used to detect the temperature t3 of the condenser outlet.

When t1, t2 and t3 all reach the corresponding set temperature threshold, the compressor is controlled to operate at a second frequency, the fan operates at a second rotating speed, wherein the second frequency is low frequency (such as 30-50 Hz), the second rotating speed is high rotating speed (such as 2500-6000 r/min), the operating frequency of the compressor is reduced to low frequency operation, high frequency operation is not performed any more, meanwhile, the rotating speed of the impeller fan is increased, the air volume is increased, and the large air volume operation is performed, and the temperature in the barrel body can be kept at the drying temperature through the logic. The drying time can be greatly shortened by improving the air quantity, the clothes can be quickly dried by logical combination, energy is saved, and the problems of long drying time and energy consumption of the heat pump washing and drying integrated machine are solved.
In step S505, it is determined whether the temperature T4 of the inlet of the tub is less than the set value T1 and the temperature T5 of the outlet of the condenser is less than the set value T3.

When the clothes to be dried are dried, the step S509 is entered to end the drying process; when the laundry to be dried is not dried, the drying process returns to step S505 to continue drying.
In step S509, the drying process is ended.
The heat pump washing and drying all-in-one machine in the related art is single in drying logic and simple in logic judgment, so that the drying time and energy conservation are difficult to take into account.
