Based on the clothes treatment device in the related art, such as a clothes dryer, a washing and drying integrated machine and other household appliances with drying functions, after dehydration is finished, the compressor and the fan are controlled to be started, clothes are dried, and the problems of long drying time and high energy consumption exist. The method provided by the embodiment of the application can be realized by a computer program, and each step in the drying control method provided by the embodiment of the application is completed when the computer program is executed. 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 according to an embodiment of the present application, as shown in fig. 1, where the drying control method includes the following steps:
step S101, determining to enter a dehydration stage, controlling the compressor to operate at a first frequency to generate hot air.
The heat pump clothes dryer utilizes a heat pump system to extract heat from the surrounding environment and transfer the heat to an object to be dried (such as clothes and the like), and 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 an increased temperature, and the refrigerant is at a reduced temperature. In the embodiment of the application, the clothes treatment device particularly refers to a variable-frequency 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 clothes dryer as an example, and the clothes dryer hereinafter will be referred to as a heat pump clothes dryer unless otherwise specified.
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 air inlet pipe of the compressor to form a refrigerant circulation path of the compressor, the condenser, the throttling device, the evaporator and the compressor, the refrigerant is compressed into high-temperature and high-pressure gaseous refrigerant in the compressor, the high-temperature and high-pressure gaseous refrigerant is discharged out of the compressor through the exhaust port of the compressor and then enters the condenser to condense and release heat, the high-pressure and high-pressure gaseous refrigerant is gradually converted into high-pressure liquid refrigerant, the high-pressure liquid refrigerant flows out of the condenser and enters the throttling device to perform throttling, temperature reduction and depressurization, the high-pressure and low-pressure liquid refrigerant is then discharged out of the throttling device and enters the evaporator to absorb heat in the surrounding environment and evaporate continuously, and is converted into low-pressure gaseous refrigerant, and the low-pressure gaseous refrigerant is discharged out of the evaporator and then reentered into the compressor through the air inlet of the compressor to compress, and thus the reciprocating circulation is performed.
The compressor is used as the power of refrigeration cycle, plays a decisive role in the whole drying process, and the condenser can generate hot air through the operation of the compressor to provide a heat source for the barrel.
The drying control apparatus of the 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, 60Hz.
Step S102, controlling a fan to run at a first rotating speed, and introducing the hot air into a barrel body of the clothes treatment device.
The drying control equipment controls the fan to start to run at a first rotation speed to drive the impeller to rotate, and hot air is introduced into the barrel body 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, 2000r/min.
In the embodiment of the application, after the dehydration stage is determined, the drying control equipment controls the compressor and the fan to operate simultaneously, so that the temperature in the barrel body can quickly reach the drying temperature, and clothes can be quickly dried, thereby shortening the drying time, reducing the energy consumption and saving energy.
The drying control method provided by the embodiment of the application is applied to a clothes treatment device, and comprises the following steps: determining to enter a dehydration stage, controlling the compressor to operate at a first frequency to produce hot air; the fan is controlled to run at a first rotation speed, hot air is introduced into the barrel body of the clothes treatment device, so that the object to be dried in the barrel body is pre-dried, and the temperature in the barrel can be quickly increased by controlling the compressor and the fan to run simultaneously, so that a bedding is made for entering a main drying stage. Therefore, the time length of the whole drying process can be shortened, and meanwhile, the energy consumption can be reduced, and the energy conservation is realized.
On the basis of the embodiment shown in fig. 1, the embodiment of the present application further provides a drying control method, and fig. 2 is a schematic flow chart of another implementation of the drying control method provided by the embodiment of the present application, as shown in fig. 2, where 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.
The drying control apparatus of the dryer controls a compressor of the dryer to operate at a first frequency after entering a dehydration stage. The first frequency can be relatively high, and the compressor is high in frequency, so that hot air can be promoted to be generated, and the temperature rising rate is further improved. In the embodiment of the present application, the value of the first frequency may be any value between 50Hz (hertz) and 100Hz, for example, 60Hz.
Step S202, controlling a fan to run at a first rotating speed, and introducing the hot air into a barrel body of the clothes treatment device.
The drying control equipment controls the fan to start to run at a first rotation speed to drive the impeller to rotate, and hot air is introduced into the barrel body of the clothes treatment device. The fan can be operated at a relatively low rotational speed, so that the temperature of the generated hot air is not affected by the fan, and normally, if the rotational speed of the fan is high, the temperature of the hot air is reduced, so that the first rotational 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, 2000r/min.
In the embodiment of the application, after entering a dehydration stage, the compressor is controlled to run at high frequency, and the fan is controlled to run at low speed, so that hot air with smaller air quantity is introduced into the barrel when the temperature in the barrel is lower, and the temperature of the exhaust pipe of the compressor, the temperature of the outlet of the condenser and the temperature of the air inlet of the barrel can be quickly increased to set values, thereby quickly increasing the temperature in the barrel of the clothes dryer and quickly enabling the temperature in the barrel to reach the drying temperature.
Step S203, detecting a temperature in the laundry treating apparatus.
Here, detecting the temperature inside the dryer may detect 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.
Step S204, determining that the temperature in the clothes treating apparatus 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 detecting the temperature in the clothes dryer, judging whether the detected temperature meets a first preset condition. Here, the first preset condition is for determining whether the temperature in the tub of the dryer rises to a set drying temperature. In some embodiments, whether the temperature in the dryer rises to the drying temperature may be determined according to at least one of the temperature of the compressor discharge pipe, the temperature of the condenser outlet, and the temperature of the inlet port of the tub. 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, at the moment, the temperature in the barrel body reaches the drying temperature, the operation frequency of the compressor is reduced to a second frequency, and the drying energy consumption of the clothes dryer can be reduced, so that energy conservation is realized. Here, the value of the second frequency may be any value between 30Hz and 50Hz, for example 40Hz.
Step S205, controlling the fan to operate at a second rotating speed.
Here, the second rotational speed is greater than the first rotational speed. In the embodiment of the present application, the value of the second rotation speed may be any value between 2500r/min and 6000r/min, for example, 5000r/min.
When the temperature in the clothes dryer meets the first preset condition, the temperature in the barrel body reaches the pre-drying temperature, at the moment, in order to accelerate the drying speed and shorten the drying time, the rotating speed of the fan is increased from the first rotating speed to the second rotating speed, and hot air with larger air quantity is introduced into the barrel body by increasing the rotating speed of the fan, so that the water on the clothes to be dried can be quickly evaporated into steam, the clothes can be dried as soon as possible, and the drying time is greatly shortened.
In the embodiment of the application, when entering a dehydration stage, 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 compressor is controlled to run at a low frequency, the fan rotates at a high speed, the temperature in the barrel body can reach the drying temperature quickly, the energy consumption is reduced while clothes are dried quickly, the energy saving 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 comprises the following steps: determining to enter a dehydration stage, controlling the compressor to operate at a first frequency to produce hot air; controlling a fan to run at a first rotation speed, and introducing the hot air into a barrel body of the clothes treatment device; detecting a temperature within the laundry treatment apparatus; determining that the temperature in the clothes treatment device meets a first preset condition, and controlling the compressor to operate at a second frequency, wherein the second frequency is smaller than the first frequency; and controlling the fan to run at a second rotating speed, wherein the second rotating speed is larger than the first rotating speed. And (3) introducing the hot air into the barrel body of the clothes treatment device so as to pre-dry the object to be dried in the barrel body, and controlling the compressor and the fan to operate simultaneously, so that the temperature in the barrel body can be quickly increased, and a bedding is made for entering 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 high-frequency operation of the compressor and the low-speed rotation of the fan; when the temperature in the barrel body reaches the drying temperature, the compressor is controlled to run at low frequency and the fan rotates at high speed, so that the drying time can be shortened, the energy consumption is reduced while the clothes are dried rapidly, and the energy saving is realized.
In some embodiments, the dehydration stage described 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, i.e., when the drying stage is entered, the laundry to be dried in the tub is not dehydrated yet, or is dehydrated yet, but the dehydration is not complete, and the moisture of the laundry to be dried is still relatively large. At this time, after entering the drying stage, the drying stage is first entered to execute the drying process, and the pre-drying is performed while the drying process is executed, so that the temperature in the tub body can be quickly increased to the drying temperature, and thus the duration of the whole drying process can be shortened.
The dehydration stage is an independent dehydration stage, namely, when entering the drying stage, the clothes to be dried in the barrel body are dehydrated and thoroughly dehydrated. Pre-drying the clothes to be dried while entering a dehydration stage to execute a dehydration program; after the dehydration stage is finished, the drying stage is started, the temperature in the barrel body can be quickly increased to the drying temperature after the drying stage is started through pre-drying, and thus the duration of the whole drying process can be shortened.
In some embodiments, the drying control apparatus may determine whether the temperature in the dryer satisfies the first preset condition by the temperature of the hot air entering the tub, and at this time, step S203 "detect the temperature in the laundry treating device" in the embodiment shown in fig. 2 may be implemented as:
In step S203a1, the temperature of the air 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 the dry high temperature entering the tub of the dryer is detected.
In the embodiment of the application, the temperature of the air entering the dryer barrel can be detected by the temperature sensor, and the temperature sensor is arranged at the air inlet of the dryer barrel.
At this time, "determining that the temperature in 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:
in step S204a1, it is determined 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. When the first temperature reaches the first temperature threshold, that is, when the first temperature is greater than the first temperature threshold, determining that the temperature in the drum body 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 tub of the dryer does not meet the first preset condition, and at this time, the step S201 is returned to control the compressor to continue to operate at the first frequency.
In some embodiments, the drying control apparatus may also determine whether the temperature in the dryer satisfies the first preset condition through the temperature of the compressor discharge pipe, and at this time, step S203 "detect the temperature in the laundry treating device" in the embodiment shown in fig. 2 may be implemented as:
step S203b1, detecting a temperature of the compressor discharge pipe to obtain a second temperature.
Here, the temperature of the compressor discharge pipe, i.e., the temperature of the hot air at a high temperature of drying discharged from the compressor is detected.
In the embodiment of the application, the temperature of the air discharged from the compressor can be detected by a temperature sensor arranged at the outlet of the exhaust pipe of the compressor of the clothes dryer.
At this time, "determining that the temperature in 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 judges whether the second temperature reaches a second temperature threshold. When the second temperature reaches the second temperature threshold, that is, when the second temperature is greater than the second temperature threshold, determining that the temperature in the drum body of the clothes dryer meets the 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 at this time, the step S201 is returned to control the compressor to continue to operate at the first frequency.
In some embodiments, the drying control apparatus may also determine whether the temperature in the dryer satisfies the first preset condition by the temperature of the dryer condenser outlet, and at this time, step S203 "detect the temperature in the laundry treating device" in the embodiment shown in fig. 2 may be implemented as the following steps:
step S203c1, detecting a temperature of an outlet of the condenser of the laundry treating apparatus to obtain a third temperature.
Here, the temperature of the outlet of the condenser, i.e., the temperature of the dry high-temperature hot air condensed by the condenser, is detected.
In the embodiment of the application, the temperature of the condenser outlet can be detected by a temperature sensor, and the temperature sensor is arranged at the condenser outlet of the clothes dryer.
At this time, "determining that the temperature in 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 S204c1, determining whether the third temperature reaches a third temperature threshold.
After detecting the third temperature, the drying control device judges whether the third temperature reaches a third temperature threshold. When the third temperature reaches the third temperature threshold, that is, when the third temperature is greater than the third temperature threshold, determining that the temperature in the drum body of the clothes dryer meets the first preset condition, and continuing to execute the step S204; when the third temperature does not reach the third temperature threshold, that is, the third temperature is less than or equal to the third temperature threshold, it is determined that the temperature in the tub of the dryer does not meet the first preset condition yet, and at this time, the step S201 is returned to control the compressor to continue to operate at the first frequency.
In some embodiments, the drying control apparatus may determine whether the temperature in the dryer satisfies the first preset condition by any two or three of the temperature of the hot air entering the tub, the temperature of the compressor discharge pipe, and the temperature of the condenser outlet, and step S203 in the embodiment shown in fig. 2 performs two or three steps corresponding to step S203a1, step S203b1, and step S203c1, and detects the air temperature at different positions through a plurality of temperature sensors provided at different positions, so that the accuracy of determining the temperature in the laundry treating apparatus may be improved. The following description will be made taking as an example that the drying control apparatus determines whether the temperature in the dryer satisfies the first preset condition by three temperatures of the temperature of the hot air entering the tub, the temperature of the compressor discharge pipe, and the temperature of the condenser outlet, and at this time, step S203 "detect the temperature in the laundry treating apparatus" in the embodiment shown in fig. 2 may be implemented as:

step S501, a drying program is started.
Step S502, starting a dehydration program, controlling the compressor to operate at a first frequency, and controlling the fan to operate at a first rotational 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, the first frequency is high (such as 50 to 100 Hz), the first rotating speed is low (such as 1000 to 2500 r/min), the compressor operates at a high frequency, the fan operates at a low rotating speed, the small air quantity is kept, at the same time, the dehydration operation is started at the same time, the dehydration program is performed according to a normal program, namely, the dehydration and heat pump system, the fan operates at the same time, and the temperature in the barrel can be quickly increased to reach a set value through the logic.

When the laundry to be dried has been dried, the process proceeds to step S509 to end the drying process; when the laundry to be dried is not dried, the process returns to step S505 to continue drying.
Step S509, the drying process is ended.
