As shown in fig. 1, the method specifically includes the following steps:

step 101: the method comprises the steps of sequentially obtaining the temperature in a first barrel in a current washing barrel, the temperature in a second barrel after blowing hot air for a first preset time, the temperature in a third barrel after blowing cold air for a second preset time and the temperature in a fourth barrel after blowing hot air for the first preset time again.

The execution main body of the embodiment of the application is clothes processing equipment with a drying function, such as a clothes dryer, a washing and drying integrated machine and the like. The user places a load to be dried in a washing tub of the laundry treating apparatus and starts a drying process through a control panel of the laundry treating apparatus. Or, the laundry treating apparatus finishes washing the load, and automatically enters a drying process when the dehydration is finished.

As shown in fig. 2, when the current drying program is started, the laundry treating apparatus implements a hot and cold air combination manner by the operations of the following steps S1-S7, and collects temperatures in a plurality of tubs, and specifically includes:

s1: the current temperature in the first tub in the washing tub is acquired.

The temperature in the first tub in the washing tub is detected by a temperature sensor provided in the washing tub of the laundry treating apparatus. Wherein the temperature sensor may be disposed under a filter screen of the laundry treating apparatus, for detecting a temperature of wind blown into the washing tub, as an in-tub temperature in the washing tub. Or the temperature sensor can also be arranged on the side wall or the door cover of the washing barrel and used for detecting the air temperature in the washing barrel, and the detected air temperature is taken as the temperature in the washing barrel.

S2: and controlling a heating pipe and a fan of the drying system to be started for a first preset time so as to blow hot air into the washing barrel.

In the embodiment of the application, a drying system is arranged in the clothes treatment equipment, the drying system comprises a drying tunnel, a heating pipe, a fan and a condenser, the heating pipe and the fan are positioned in the drying tunnel, and the drying tunnel, the condenser and the washing barrel form a circulating air duct.

And after the temperature in the first barrel is acquired by the temperature sensor, a heating pipe and a fan in the drying system are controlled to be started. The heating pipe heats air, and the flabellum of fan drives hot-air flow when rotating, forms hot-blastly, and hot-blastly blows into the washtub along the drying tunnel in, continuously blows the hot-blastly for the first predetermined duration in to the washtub.

The first preset time period may be 6min or 7min, etc. The embodiment of the application does not limit the specific value of the first preset duration, and the practical application can be limited according to requirements.

By blowing hot air into the washing barrel, the hot air can accelerate the evaporation of water in the load, and the drying effect is achieved. And the hot air blowing can raise the temperature in the washing tub, so that the load capacity can be judged according to the temperature rise condition.

S3: and controlling the heating pipe to be closed according to the first preset time, and obtaining the temperature in the second barrel in the washing barrel.

And starting timing when the heating pipe is controlled to start heating, comparing the timing duration with a first preset duration, and continuing to blow hot air if the timing duration is less than the first preset duration. If the timed time length is equal to the first preset time length through comparison, the heating pipe is controlled to be closed, and the temperature in the second barrel in the washing barrel is detected through a temperature sensor arranged in the clothes treatment equipment.

S4: keeping the fan on for a second preset time to blow cold air into the washing barrel.

And after the temperature in the second barrel is collected by the temperature sensor, keeping the fan open to blow cold air into the washing barrel for a second preset time. The second preset duration may be 3min or 4min, and the specific value of the second preset duration is not limited in the embodiment of the present application, and may be set according to a requirement in practical application.

S5: and acquiring the temperature in a third barrel in the washing barrel according to the second preset time.

And (5) starting timing when the heating pipe is closed in the step (S3), comparing the timing duration with a second preset duration, and if the timing duration is less than the second preset duration, continuing to blow cold air. And if the timed time length is equal to a second preset time length through comparison, detecting the temperature in a third barrel in the washing barrel through a temperature sensor.

S6: and controlling the heating pipe to be opened for the first preset time again so as to blow hot air into the washing barrel.

And after the temperature in the third barrel is obtained, the heating pipe is controlled to be opened again for heating, hot air is blown into the washing barrel, and the heating is continued for a first preset time.

S7: and acquiring the temperature in a fourth barrel in the washing barrel according to the first preset time.

And controlling the heating pipe to start timing when being opened, and detecting the temperature in a fourth barrel in the washing barrel through the temperature sensor when the timing duration reaches a first preset duration.

In other embodiments of the present application, it is contemplated that the load may be heated for washing, or the laundry treatment apparatus may have just completed a drying process, etc. In these scenarios, when the current drying program is started, the current temperature inside the washing tub may be high, so that the temperature inside the washing tub may not be directly detected by the temperature sensor when the current temperature inside the first tub is obtained in step S1. Instead, as shown in fig. 3, the first tub inside temperature is obtained through the operation of step S1'.

S1': controlling a fan of the drying system to be started for a third preset time period so as to blow cold air into the washing barrel; and acquiring the temperature in the first barrel in the washing barrel according to the third preset time.

When the clothes processing equipment determines that the current drying program is started, the fan in the drying system is controlled to be started, fan blades rotate after the fan is started to drive air to flow to form air, and the air is blown into the washing barrel through the drying tunnel. Since heating is not performed at this time, the temperature of the air blown into the washing tub is not high, and therefore, the air is called cold air. Thus, cold air is blown into the washing barrel for a third preset time.

The third preset time period may be 2min or 3min, etc. The embodiment of the application does not limit the specific value of the third preset duration, and the third preset duration can be limited according to requirements in practical application.

In one implementation, the fan of the drying system is linked with the motor and the washing tub of the laundry treatment apparatus, and as long as the motor is turned on, both the fan blades of the fan and the washing tub rotate with the motor.

And starting timing when the fan is controlled to start cold air blowing, comparing the timing time with a third preset time, and if the timing time is less than the third preset time, continuously controlling the fan to blow cold air. If the compared timed length is equal to the third preset length, detecting the temperature in the first tub in the washing tub by a temperature sensor provided in the laundry treating apparatus. The temperature in the first tub collected after blowing the cold air for the third preset time period may be regarded as the initial ambient temperature of the environment in which the load is located.

By blowing cold air into the washing barrel, on one hand, the cold air can promote water in the load to evaporate, and a certain drying effect is achieved. On the other hand, the temperature in the washing barrel can be reduced by blowing cold air, so that the temperature in the washing barrel is reduced to be close to room temperature, the phenomenon that the temperature in the first barrel detected for the first time is too large to be different from the temperature in the barrel detected in the subsequent cold air blowing stage is avoided, the complexity of an algorithm is reduced, and the accuracy of load judgment according to the temperature in the barrel detected for the subsequent time is improved.

As shown in fig. 3, after the step S1 'is performed, the step S2' is performed: and controlling a heating pipe of the drying system to be opened for a first preset time so as to blow hot air into the washing barrel. Since the blower is turned on in step S1 ', it is not necessary to turn on the blower again in step S2'.

After the temperature sensor detects the temperature in the fourth barrel, the fan and the heating pipe can be continuously kept open, and hot air is blown into the washing barrel for drying. And the temperature in the barrel is detected in real time through the temperature sensor, and when the temperature in the barrel is detected to be higher than the preset temperature, the heating pipe is controlled to be closed. And when the temperature in the barrel is detected to be lower than the preset temperature, the heating pipe is controlled to be opened. So as to maintain the temperature in the barrel at a preset temperature for drying, wherein the preset temperature can be 70 ℃ or 80 ℃ and the like

In another implementation manner, the temperature in the barrel may also be maintained within a preset temperature interval, and when it is detected that the temperature in the barrel is greater than an upper limit value of the preset temperature interval, the heating pipe is controlled to be closed.

Step 102: and determining a weight interval corresponding to the current load according to the temperature in the first barrel, the temperature in the second barrel, the temperature in the third barrel, the temperature in the fourth barrel and the first preset time.

After the temperature in the first tub, the temperature in the second tub, the temperature in the third tub, and the temperature in the fourth tub are collected through the operation of step 101, the total heat capacity of the load and the water in the current washing tub is determined according to the collected temperatures in the respective tubs and the first preset duration of the hot air blowing stage.

Specifically, according to the first barrel internal temperature, the second barrel internal temperature, the third barrel internal temperature, the fourth barrel internal temperature and the first preset time length, the energy balance temperature when the heat absorbed by the load is equal to the heat emitted by the load and the consumption time length required by the load to reach the energy balance temperature are calculated.

In the present example, the function to which the temperature change in the tub during heating is conformed in the washing tub was fitted through a large number of experiments, as shown in formula (1),

T_out＝T_in+f(τ，Δt)(T_∞-T_in)…(1)

in the formula (1), T_outIs the temperature in the barrel at the end of heating, T_inIs the temperature in the barrel at the beginning of heating, Δ T is the duration of heating, T_∞The energy balance temperature when the load absorbs heat and emits heat is equal, and tau is the temperature T in the barrel from the beginning of heating_inHeating to energy balance temperature T_∞The required elapsed time.

The temperature in the first barrel is increased to the temperature in the second barrel in one temperature increasing process. The first barrel internal temperature is taken as the barrel internal temperature T at the beginning of heating_inThe temperature in the second barrel is taken as the temperature T in the barrel at the end of heating_outThe first preset duration of the hot air blowing is the duration Δ t of the heating. Substituting the temperature in the first barrel, the temperature in the second barrel and the first preset time into the formula (1) to obtain an energy balance temperature T_∞And two unknown variables of consumption duration tauEquation of the quantity.

Similarly, the third internal temperature obtained in the second cold-hot air combining process is set as the internal temperature T at the start of heating_inThe fourth barrel internal temperature is regarded as the barrel internal temperature T at the end of heating_outSubstituting the first preset duration of the hot air blowing as the duration delta T of the heating into the formula (1) to obtain another energy balance temperature T_∞And the consumption duration τ.

The two equations are solved simultaneously to calculate the energy balance temperature T_∞And a consumption time period τ.

In other embodiments of the present application, a combination of hot air and cold air may be performed more times in step 101, for example, after step S7, cold air is blown again for a certain period of time to detect the temperature in the primary barrel, and then hot air is blown again for a certain period of time to detect the temperature in the primary barrel. Through the operation of carrying out cold and hot wind combination many times, gather the barrel internal temperature before beginning to heat in the process of rising the temperature many times and the barrel internal temperature after the heating is finished, then solve out a plurality of energy balance temperature T according to formula (1)_∞And a plurality of elapsed time periods tau. Calculating a plurality of energy balance temperatures T_∞Is taken as the final energy balance temperature T_∞And calculating an average value of the plurality of consumption periods τ as a final consumption period τ. The energy balance temperature T is determined by calculating the average value through a plurality of times of combined operations of cold air and hot air_∞And a consumption time tau, capable of increasing the calculated energy balance temperature T_∞And the accuracy of the elapsed time period τ.

Obtaining the energy balance temperature T by any of the above-mentioned methods_∞And determining the current total heat capacity of the load and water in the washing tub according to the temperature in the first tub, the calculated energy balance temperature and the consumption duration after the consumption duration tau.

The heat quantity and the consumption time required for the temperature of the load to rise from the initial ambient temperature to the energy equilibrium temperature can be expressed by the thermodynamic equation shown in equation (2).

In the formula (2), T_∞To balance the temperature, T, with energy_coolIs the initial ambient temperature, and τ is the temperature from the initial ambient temperature T_coolThe length of time spent heating to the energy balance temperature, Q_elFor heating power of the heating tube, C_totIs the heat capacity.

In the embodiment of the present application, the temperature in the first barrel is taken as the initial ambient temperature T_coolSubstituted into the above equation (2). And calculating the energy balance temperature T according to the formula (1)_∞Duration of consumption tau and known heating power Q_elSubstituting into the above formula (2), calculating to obtain the heat capacity C_tot。

Wherein the heat capacity C thus calculated_totThe total heat capacity of the load and the water in the current washing barrel is determined, and then the corresponding weight interval of the load is determined according to the total heat capacity. Specifically, the material type of the load and a preset water content interval of the load are obtained. And acquiring the specific heat capacity corresponding to the load according to the material type of the load. And determining a weight interval corresponding to the load according to the water content interval of the load, the total heat capacity and the specific heat capacity corresponding to the load.

The corresponding relation between different material types and specific heat capacities is configured in the clothes treatment equipment in advance. When a user puts a load into the washing tub and starts a washing process or a drying process for the load, the material type of the current load may be set on the control panel of the laundry treating apparatus. The laundry treating apparatus obtains a material type of a load set by a user through a control panel. Or, the laundry processing apparatus may be provided with a camera device, and the camera device may capture an image of the load during the process of putting the load into the washing tub, and automatically identify the material type of the load according to the texture feature of the load in the image by processing the captured image. After the material type of the load is obtained through any one of the above manners, the specific heat capacity corresponding to the load is obtained from the mapping relation between the material type and the specific heat capacity configured in advance according to the material type of the load.

In the embodiment of the application, a load moisture content interval at the beginning of the drying program is measured in advance through a large number of tests, and the load moisture content interval is configured in the clothes treatment equipment in advance, wherein the load moisture content interval can be 30% -70% or 40% -75%, and the like. In other embodiments, it is contemplated that the moisture content of the different material types of the load may be different, such as a cotton-like load having a greater moisture content, or a chemical fiber-like or silk-like load having a lesser moisture content. Therefore, the water content intervals of the load corresponding to the loads of different material types can be measured through a large number of tests, and the mapping relation between the material types and the water content intervals of the load is configured in advance in the clothes treatment equipment. And after the material type of the current load is obtained through any one of the above modes, obtaining a corresponding load water content interval from the preset mapping relation.

And after the specific heat capacity corresponding to the load, the current total heat capacity in the washing barrel and the preset load water content interval are obtained, determining an upper limit load proportion and a lower limit load proportion corresponding to the load according to the preset load water content interval, the specific heat capacity of water and the specific heat capacity corresponding to the material type of the load. The upper limit load share ratio and the lower limit load share ratio are as shown in equation (3):

in the formula (3), K_maxAt the upper limit duty ratio, K_minAt a lower limit of load ratio, RMC_minThe lower limit value of the moisture content interval of the load, RMC_maxIs the upper limit value of the interval of the water content of the load, C_{Water (W)}Is the specific heat capacity of water, C_ClothesIs the specific heat capacity of the load.

And multiplying the upper limit load ratio by the total heat capacity to obtain the weight upper limit value corresponding to the current load. And multiplying the lower limit load ratio by the total heat capacity to obtain the weight lower limit value corresponding to the current load. The upper weight limit value and the lower weight limit value constitute a weight section to which the weight of the current load belongs.

In other embodiments of the present application, the above-described upper limit duty ratio and lower limit duty ratio may also be preconfigured directly in the laundry treating apparatus. After obtaining the total heat capacity of the load and the water in the current washing tub according to the above formula (2), directly calculating the product of the upper limit load ratio and the total heat capacity, and the product of the lower limit load ratio and the total heat capacity to obtain the weight interval to which the weight of the current load belongs. Therefore, the calculation process of the upper limit load ratio and the lower limit load ratio is not needed in the drying process, the calculation amount is reduced, and the time for judging the load amount is shortened.

The method comprises the steps of obtaining the temperature in the washing barrel in the multiple temperature rise processes in a cold and hot air alternating operation mode, calculating the total heat capacity in the current washing barrel according to the obtained temperature in the washing barrel and based on the thermodynamic principle of the temperature rise processes, and judging the weight interval to which the weight of the current load belongs according to the load water content interval when the drying program starts. Therefore, the judgment process of the load can be realized only by depending on the temperature sensor without additionally arranging other sensors in the clothes treatment equipment, and the cost is low. And the weight interval to which the weight of the load belongs can be accurately judged instead of the magnitude grade of the load in a general way, so that the judgment of the load is more accurate.

After the weight interval corresponding to the current load is judged through the embodiment of the application, the judgment can be carried out according to the weight interval. Firstly, according to the weight interval corresponding to the load, the weight interval corresponding to the water in the current washing barrel is determined. After the total heat capacity in the current washing tub and the specific heat capacity corresponding to the load are obtained in the above manner, the weight interval corresponding to the water in the current washing tub is determined according to the total heat capacity, the specific heat capacity corresponding to the load, the specific heat capacity of the water and the weight interval corresponding to the load.

Specifically, the upper limit value and the lower limit value of the weight interval of the load are multiplied by the specific heat capacity corresponding to the load, respectively, to obtain the heat capacity interval corresponding to the load. And respectively calculating the difference value between the upper limit value and the lower limit value of the heat capacity interval corresponding to the total heat capacity and the load to obtain the heat capacity interval corresponding to the water in the current washing barrel. The upper limit value and the lower limit value of the thermal capacity interval of the water are respectively divided by the specific heat capacity of the water, and the weight interval of the water is obtained.

And determining a first drying time interval required for evaporating the water in the washing tub according to the corresponding weight interval of the water. First, an upper limit value of the amount of heat required to evaporate water at an upper limit value of a water weight range and a lower limit value of the amount of heat required to evaporate water at a lower limit value of the water weight range are determined. According to the heating power of the heating pipe, the upper heat value and the lower heat value, the upper limit value of the drying time required for evaporating the water with the upper limit value of the water weight interval and the lower limit value of the drying time required for evaporating the water with the lower limit value of the water weight interval are respectively determined. The upper limit value and the lower limit value of the drying time period form a first drying time period interval required by the evaporation of the water in the current washing tub.

After the first drying time interval required for evaporating the water in the washing tub is obtained in the above manner, the lower limit value of the first drying time interval is compared with the fourth preset time interval, and the fourth preset time interval may be 1 hour or 1.5 hours and the like. The embodiment of the present application does not limit the specific value of the fourth preset duration, and the setting can be performed according to the requirement in practical application.

If the lower limit value of the first drying time interval is greater than or equal to the fourth preset time interval, the drying time required by the current drying program is longer, and in order to improve the accuracy of load judgment, the load can be judged again in a cold and hot air combined mode. Specifically, after the lower limit value of the first drying time interval is determined to be greater than or equal to the fourth preset time, the current drying time is compared with the fifth preset time, and the current drying time is the time between the starting of the current drying program and the current time.

The fifth preset time period may be 40min or 50min, etc. The embodiment of the application does not limit the specific value of the fifth preset duration, and the setting can be performed according to the requirement in practical application.

And if the current drying time reaches the fifth preset time, re-determining the weight interval corresponding to the load. Specifically, when the current drying time reaches a fifth preset time, the fan of the drying system is controlled to be started for a sixth preset time, and the temperature in the fifth barrel in the washing barrel is obtained through the temperature sensor according to the sixth preset time. And then, the heating pipe of the drying system is controlled to be opened for a first preset time, and the temperature in the sixth barrel in the washing barrel is obtained according to the first preset time.

After the temperature in the fifth bucket and the temperature in the sixth bucket are obtained in the above manner, the weight interval corresponding to the load is determined again according to the operation of step 102, based on the temperature in the third bucket, the temperature in the fourth bucket, the temperature in the fifth bucket, the temperature in the sixth bucket, and the first preset time period. Or, according to the first barrel internal temperature, the second barrel internal temperature, the fifth barrel internal temperature, the sixth barrel internal temperature and the first preset time, re-determining the weight interval corresponding to the load according to the operation of the step 102.

When the load is large and the required drying time is long, after the drying is carried out for a period of time, the weight interval to which the load belongs is determined again in a cold and hot air combined mode, and the accuracy of load judgment can be improved.

And after the weight interval of the load is determined again, judging the trunk according to the determined weight interval. Specifically, the weight interval corresponding to the water currently in the washing tub is newly determined according to the newly determined weight interval corresponding to the load. And determining a second drying time interval required for evaporating the water according to the re-determined weight interval corresponding to the water. And judging the drying of the current drying program according to the second drying time interval.

Specifically, during the operation of the current drying program, the temperature in the tub in the washing tub is detected in real time by the temperature sensor, and the current drying time period is recorded in real time. And judging whether the detected temperature in the barrel reaches a preset temperature threshold value or not, and judging whether the current drying time is located in a second drying time interval or not. And if the current drying time is judged to be in the second drying time interval and the current temperature in the barrel reaches the preset temperature threshold, determining that the load is dried, and controlling the current drying program to end. And if the temperature in the barrel still does not reach the preset temperature threshold when the current drying time reaches the upper limit value of the second drying time interval, controlling the current drying program to end, or controlling the current drying program to end after the drying set time is prolonged. The set time period can be 10min, 20min or 30min and the like. The preset temperature threshold may be a sum of an energy equilibrium temperature at which the load is conserved and a preset deviation value, and the preset deviation value may be 4 ℃, 8 ℃, 10 ℃ or the like.

If the lower limit value of the first drying time interval is compared with the fourth preset time interval, and the lower limit value of the first drying time interval is determined to be smaller than the fourth preset time interval, the drying time required by the current drying program is indicated to be shorter, and the drying is directly determined according to the currently determined weight interval of the load. Namely, the drying is judged according to the first drying time interval. The process of determining the dryness according to the first drying time interval is the same as the process of determining the dryness according to the second drying time interval, and is not repeated herein.

And (3) judging the drying according to the judged weight interval of the load, so that the drying judgment accuracy is improved, the over-drying or non-drying condition is reduced, and the drying effect is improved.
