The clothes drying method provided by the embodiment can be applied to a heat pump clothes dryer. The heat pump clothes dryer in the embodiment can be a common heat pump clothes dryer or a heat pump clothes dryer with auxiliary heat.
Fig. 1 is a schematic structural view of a heat pump clothes dryer to which a clothes drying method according to an embodiment of the present invention is applied. As shown in fig. 1, the heat pump clothes dryer includes a heat pump (which may also be referred to as a heat pump system) 22, a clothes drying tub 21, and a blower 24. The heat pump 22 includes: an evaporator 221, a condenser 222, a compressor 224, and a throttling element 223. Wherein the output of the evaporator 221 is connected to the input of the compressor 224. An output of the compressor 224 is connected to an input of the condenser 222.

The clothes drying method provided by the embodiment can improve the drying efficiency on the premise of saving the power consumption. The following describes in detail the clothes drying method and technical effects provided by the present embodiment.
Fig. 3 is a flowchart of a laundry drying method according to an embodiment of the present invention. The present embodiment is applicable to a case where laundry is dried by a dryer, and the method may be performed by a laundry drying apparatus, which may be implemented in hardware and/or software, and which may be configured in a heat pump dryer. The laundry drying device may be a controller in a heat pump dryer, for example. As shown in fig. 3, the method includes the following steps.
Step 301: and acquiring drying parameters of the clothes to be dried in the drying process.
The drying process of the present embodiment refers to a process in which drying has already been started. In the drying process, the laundry to be dried in the present embodiment is set in the drying tub. The clothes to be dried in the embodiment may be fabrics such as clothes, household articles (e.g. curtains), etc.
The drying parameters in this embodiment are parameters that can characterize the drying stage in which the laundry to be dried is located.
Optionally, the drying parameters of the laundry to be dried include at least one of: the temperature of the clothes to be dried, the water content of the clothes to be dried and the weight variation of the clothes to be dried.
Based on different implementation modes of the drying parameters, different kinds of sensors can be set to acquire the drying parameters of the clothes to be dried. The drying parameter of the laundry to be dried is, for example, a temperature of the laundry to be dried. Correspondingly, a temperature sensor may be provided in the dryer, through which the temperature of the laundry to be dried is obtained.
Step 302: and determining the current drying stage of the clothes to be dried according to the drying parameters of the clothes to be dried.
Fig. 4A is a schematic diagram showing the change of the moisture content and temperature of laundry during drying. As shown in fig. 4A, in the process of drying laundry by the dryer, the following 4 drying stages may be included. The horizontal axis in fig. 4A represents time. According to the time sequence, each drying stage is respectively as follows: a heating stage, a constant speed stage, a deceleration stage and a cold air stage. The first curve 41 in fig. 4A shows the trend of temperature over time. The second curve 42 shows the trend of the moisture content of the laundry over time.
The first stage: and (3) heating. In this stage, the temperature of the laundry to be dried is increased, and the moisture content of the laundry to be dried is maintained substantially unchanged, that is, the variation of the moisture content is less than the preset moisture content variation threshold. The main effect on the drying rate at this stage is the rate of rise in temperature. The drying rate in this embodiment refers to the rate at which the laundry is dehumidified, i.e., the rate at which the moisture in the laundry is reduced. When the temperature of the clothes to be dried rises to the preset maximum temperature T at the stage Lifting device At that time, the next stage, i.e., the constant speed stage, is entered.
And a second stage: constant speed stage. In this stage, the sensible heat absorbed by the laundry to be dried from the drying medium is substantially equal to the latent heat required for vaporization of water, and the temperature of the laundry to be dried is substantially unchanged, i.e., the variation of the temperature is less than the preset temperature variation threshold. The moisture content of laundry to be dried is decreased at a constant rate. The humidity of the drying medium decreases at a constant rate. The drying rate in the constant speed stage depends on the vaporization rate of the moisture on the surface of the material of the clothes to be dried, and the drying time is shorter as the flow rate of the drying medium is higher, the temperature is higher, the humidity is lower. When the temperature of the clothes to be dried rises to the preset maximum temperature T at the stage Constant-force device When this occurs, the next stage, i.e., the deceleration stage, is entered.
And a third stage: and a deceleration stage. In this phase, the heat imparted by the drying medium cannot be used entirely to vaporise the moisture, and a portion is used to heat the laundry to be dried. The drying rate gradually decreases and the temperature of the laundry to be dried increases. The drying rate at this time depends on the structure, shape and size of the material itself and the bulk thickness of the laundry to be dried. The parameter relation with the drying medium is not great. That is, in the deceleration stage, the drying rate is not greatly related to the temperature of the drying medium. When the temperature of the clothes to be dried rises to the preset maximum temperature T at the stage Lowering blood pressure When the next stage, i.e., the cool air stage, is entered.
Fourth stage: and (3) a cold air stage. In the later drying stage, the temperature of the clothes and the system is too high, so that a cold air stage is set in the control logic of the clothes dryer to cool the clothes, and the humidity of the drying medium and the water content of the clothes are basically kept unchanged.
In one implementation, the drying parameter of the laundry to be dried is the moisture content of the laundry to be dried. A moisture content sensor may be provided in the dryer, and the moisture content of laundry to be dried is obtained through the moisture content sensor. Based on fig. 4A, three water cut thresholds may be set. The first water content threshold is the critical water content of the heating stage and the constant speed stage. The second water content threshold is the critical water content of the constant speed stage and the deceleration stage. The third water content threshold is the critical water content of the deceleration stage and the cold air stage. And the first water content threshold value, the second water content threshold value and the third water content threshold value are sequentially reduced.
And when the water content of the clothes to be dried is determined to be larger than the first water content threshold value, determining that the current drying stage of the clothes to be dried is a heating stage.
And when the water content of the clothes to be dried is determined to be smaller than or equal to the first water content threshold value and larger than the second water content threshold value, determining that the current drying stage of the clothes to be dried is a constant-speed stage.
And when the water content of the clothes to be dried is determined to be smaller than or equal to the second water content threshold value and larger than the third water content threshold value, determining that the current drying stage of the clothes to be dried is a deceleration stage.
And when the water content of the clothes to be dried is less than or equal to the third water content threshold value, determining that the current drying stage of the clothes to be dried is a cold air stage.
In another implementation, the drying parameter of the laundry to be dried is a weight variation of the laundry to be dried. A weight sensor may be provided in the dryer, and a weight variation of laundry to be dried is acquired through the weight sensor. Three weight change thresholds may be set. The first weight change amount threshold is the critical weight change amount of the heating stage and the constant speed stage. The second weight change threshold is a critical weight change amount in the constant speed stage and the deceleration stage. The third weight change threshold is the critical weight change of the deceleration stage and the cold air stage. The first weight change amount threshold value, the second weight change amount threshold value, and the third weight change amount threshold value are sequentially decreased. The weight variation in this embodiment refers to a variation between the current weight of laundry to be dried and the initial weight (i.e., the weight when drying is not started).
When the weight change amount of the clothes to be dried is less than or equal to the first weight change amount threshold value, the current drying stage of the clothes to be dried is determined to be a heating stage.
When it is determined that the weight variation of the laundry to be dried is greater than the first weight variation threshold value and less than or equal to the second weight variation threshold value, it is determined that the current drying stage of the laundry to be dried is a constant speed stage.
When it is determined that the weight variation of the laundry to be dried is greater than the second weight variation threshold value and less than or equal to the third weight variation threshold value, it is determined that the current drying stage of the laundry to be dried is a deceleration stage.
And when the weight change amount of the clothes to be dried is determined to be larger than the third weight change amount threshold value, determining that the current drying stage of the clothes to be dried is a cold air stage.
In yet another implementation, the drying parameter of the laundry to be dried includes a temperature of the laundry to be dried. Fig. 4B is a schematic diagram of each temperature threshold. As shown in fig. 4B, in this implementation, a preset first temperature threshold T1, a preset second temperature threshold T2, and a preset third temperature threshold T3 are set. And, the preset first temperature threshold, the preset second temperature threshold, and the preset third temperature threshold are sequentially increased. The preset first temperature threshold value is smaller than the highest temperature T corresponding to the temperature rising stage Lifting device . Exemplary, a first temperature threshold ratio T is preset Lifting device 3 degrees celsius to 5 degrees celsius less. The preset second temperature threshold value is larger than the highest temperature T corresponding to the constant speed stage Constant-force device . Exemplary, the second temperature threshold ratio T is preset Constant-force device 3 degrees celsius to 5 degrees celsius greater. The preset third temperature threshold value is smaller than the highest temperature T in the deceleration stage Lowering blood pressure . Exemplary, a third temperature threshold ratio T is preset Lowering blood pressure 3 degrees celsius to 5 degrees celsius less.
In this implementation, the specific implementation procedure of step 302 may include steps 3021 to 3024.
Step 3021: and when the temperature of the clothes to be dried is less than or equal to the preset first temperature threshold value, determining that the current drying stage is a heating stage.
Step 3022: and when the temperature of the clothes to be dried is determined to be larger than the preset first temperature threshold and smaller than or equal to the preset second temperature threshold, and the duration time of the temperature of the clothes to be dried being larger than the preset first temperature threshold and smaller than the preset second temperature threshold is longer than the preset first duration time, determining that the current drying stage is a constant speed stage.
The preset first duration may be, for example, 30 seconds. Since the temperature of the laundry to be dried fluctuates in the constant speed stage, the judgment of the duration is added in the judgment process in step 3022. The current drying stage is determined to be a constant speed stage only when the temperature of the laundry to be dried is greater than a preset first temperature threshold and less than or equal to a preset second temperature threshold, and the duration of the state is greater than a preset first duration. And the preset first temperature threshold value is smaller than the highest temperature T corresponding to the temperature rising stage Lifting device . The judging mode avoids misjudgment and improves the accuracy of judging the drying stage.
Step 3023: and when the temperature of the clothes to be dried is determined to be larger than the preset second temperature threshold and smaller than or equal to the preset third temperature threshold, and the duration time of the temperature of the clothes to be dried being larger than the preset second temperature threshold and smaller than the preset third temperature threshold is longer than the preset second duration time, determining that the current drying stage is a deceleration stage.
The preset second duration may be, for example, 30 seconds. In step 3023, a determination of the duration is added in the determination process. The current drying stage is determined to be a deceleration stage only when the temperature of the laundry to be dried is greater than a preset second temperature threshold and less than or equal to a preset third temperature threshold, and the duration of the state is greater than a preset second duration. The judging mode avoids misjudgment and improves the accuracy of judging the drying stage.
Step 3024: and when the temperature of the clothes to be dried is determined to be larger than a preset third temperature threshold value, and the duration time when the temperature of the clothes to be dried is larger than the preset third temperature threshold value is longer than the preset third duration time, determining that the current drying stage is a cold air stage.
The preset second duration may be, for example, 30 seconds. In step 3024, a determination of the duration is added in the determination process. And determining the current drying stage as the cold air stage only when the temperature of the clothes to be dried is greater than a preset third temperature threshold value and the duration time of the state is longer than a preset third duration time.
The judging process of steps 3021 to 3024 may implement accurate judgment of the current drying stage.
Step 303: and when the current drying stage is determined to be the deceleration stage, controlling the heat pump clothes dryer to enter a deceleration mode.
The power consumption of the speed-down mode is smaller than that of the constant speed mode corresponding to the constant speed stage. The heat pump is in a working state in the deceleration mode, and the working mode of the clothes drying barrel in the deceleration mode is a positive and negative rotation mode. The constant speed stage is a drying stage before the deceleration stage.
Based on the analysis of each drying phase in step 302, in the deceleration phase, the drying rate depends on the structure, shape and size of the mass itself and the bulk thickness of the laundry to be dried. The parameter relation with the drying medium is not great. That is, in the deceleration stage, the drying rate is not greatly related to the temperature of the drying medium. And the power consumption of the dryer is positively correlated with the temperature of the drying medium. Therefore, in order to reduce power consumption and avoid electric energy waste, the power consumption of the speed-down mode can be smaller than the power consumption of the constant speed mode corresponding to the constant speed stage, and meanwhile, the drying rate is not affected by the reduced power consumption due to the fact that the heat pump is in a working state.
Meanwhile, in the deceleration stage, the drying rate depends on the structure, shape and size of the material itself of the laundry to be dried and the stacking thickness, and thus, in order to increase the drying rate to increase the drying efficiency, it may be possible from the viewpoint of reducing the stacking thickness of the laundry to be dried. Based on this, in the present embodiment, the operation mode of the drying tub in the deceleration mode is the forward and reverse rotation mode. It can be understood that the laundry drying barrel is in the forward and reverse rotation mode, so that the stacking thickness of laundry to be dried can be reduced, and further, the drying efficiency is improved.
The forward and reverse rotation mode in this embodiment means that the drying tub is in a state of alternately working forward and reverse rotation in a preset strategy. For example, the preset strategy may preset the fourth duration for forward rotation and the fifth duration for reverse rotation. The preset fourth time period and the preset fifth time period may be the same or different. Illustratively, the preset fourth duration and the preset fifth duration may each be 15 seconds. The normal rotation in this embodiment may be clockwise rotation, and the reverse rotation may be counterclockwise rotation. Of course, the normal rotation may be counterclockwise rotation, and the reverse rotation may be clockwise rotation.
In one implementation, the deceleration mode includes at least one of: the power of the heat pump is reduced, the rotating speed of the fan is reduced, and the rotating speed of the clothes drying barrel is reduced.
In another implementation, the heat pump clothes dryer further includes a heating assembly and a blower. In this implementation, the deceleration mode includes at least one of: and closing the heating assembly, reducing the working power of the heating assembly, reducing the power of the heat pump, reducing the rotating speed of the fan and reducing the rotating speed of the clothes drying barrel.
The clothes drying method provided by the embodiment comprises the following steps: in the drying process, the drying parameters of the clothes to be dried are obtained, the current drying stage of the clothes to be dried is determined according to the drying parameters of the clothes to be dried, and when the current drying stage is determined to be a deceleration stage, the heat pump clothes dryer is controlled to enter a deceleration mode. The power consumption of the deceleration mode is smaller than that of a constant speed mode corresponding to a constant speed stage, the heat pump is in a working state in the deceleration mode, the working mode of the clothes drying barrel in the deceleration mode is a positive and negative rotation mode, and the constant speed stage is a drying stage before the deceleration stage. In the clothes drying method, when the current drying stage is determined to be the deceleration stage, the power consumption can be reduced, the heat pump is in a working state, and the working mode of the clothes drying barrel is controlled to be the positive and negative rotation mode.
Fig. 5 is a flowchart of another laundry drying method according to an embodiment of the present invention. The embodiment will be described in detail with respect to the implementation of the current drying phase as other drying phases based on the embodiment shown in fig. 3 and various alternative implementations. As shown in fig. 5, the laundry drying method provided in this embodiment includes the following steps.
Step 501: and acquiring drying parameters of the clothes to be dried in the drying process.
Step 502: and determining the current drying stage of the clothes to be dried according to the drying parameters of the clothes to be dried.
The implementation process and technical principle of step 501 and step 301, and step 502 and step 302 are similar, and will not be described again here.
The heat pump clothes dryer in this embodiment includes a heating assembly and a blower.
Step 503: and when the current drying stage is determined to be a heating stage, controlling the heat pump clothes dryer to enter a heating mode.
The heat pump and the heating assembly are in working states in the heating mode. The rotating speed of the clothes drying barrel is the rotating speed of the first clothes drying barrel. The rotating speed of the fan is the rotating speed of the first fan. The heating stage is a drying stage before the constant speed stage.
Since in the warming phase, the drying rate at this phase is mainly affected by the warming rate. Therefore, in this embodiment, in order to increase the drying rate during the temperature increasing stage, the heat pump and the heating assembly are both in operation. And the rotating speed of the clothes drying barrel is the rotating speed of the first clothes drying barrel. The rotating speed of the fan is the rotating speed of the first fan.
Step 504: and when the current drying stage is determined to be a constant speed stage, controlling the heat pump clothes dryer to enter a constant speed mode.
The heat pump and the heating assembly are in working states in the constant speed mode. The rotating speed of the clothes drying barrel is the rotating speed of the second clothes drying barrel, and the rotating speed of the fan is the rotating speed of the second fan. The rotating speed of the second clothes drying barrel is larger than that of the first clothes drying barrel, and the rotating speed of the second fan is larger than that of the first fan.
Since the drying rate in the constant speed stage depends on the vaporization rate of the moisture of the material surface of the laundry to be dried, the drying time is shorter as the drying medium flow rate is higher, the temperature is higher, the humidity is lower. Therefore, in this embodiment, in the constant speed stage, the heat pump and the heating assembly are both in operation for increasing the drying rate. And compared with the temperature rising stage, the rotating speed of the clothes drying barrel and the rotating speed of the fan are improved, so that the flow speed of the drying medium is increased.
Step 505: and when the current drying stage is determined to be the deceleration stage, controlling the heat pump clothes dryer to enter a deceleration mode.
The power consumption of the speed-down mode is smaller than that of the constant speed mode corresponding to the constant speed stage. The heat pump is in a working state in the deceleration mode, and the working mode of the clothes drying barrel in the deceleration mode is a positive and negative rotation mode. The constant speed stage is a drying stage before the deceleration stage.
Step 505 is similar to the implementation process and technical principle of step 303, and will not be described again here.
It should be noted that, in the deceleration mode, the rotation speed of the drying tub may be smaller than the rotation speed of the second drying tub. In this embodiment, the relationship between the rotational speed of the drying tub and the rotational speed of the first drying tub in the deceleration mode is not limited. The rotational speed of the blower may be less than the second blower rotational speed. In this embodiment, the relationship between the rotational speed of the fan in the speed-reducing mode and the rotational speed of the first fan is not limited.
Step 506: and when the current drying stage is determined to be a cold air stage, controlling the heat pump clothes dryer to enter a cold air mode.
The heat pump and the heating component are in a closed state in the cold air mode. The fan is in a working state, and the cold air stage is a drying stage after the speed reduction stage.
