[0038] In the related art, the laundry treatment apparatus with drying function generally determines the drying parameter by the weight of the laundry, but in the weighing procedure, since the weighing gears are not accurate, the extremely small load with the weight range of 0-0.5 kg and the small load with the weight range of 0.5-1 kg are in the same weighing gear, so that the drying conditions of the small load and the extremely small load are the same, thereby causing the drying time to be too long in the case of drying the extremely small load, and also increasing the energy consumption.

[0039] In order to solve the above technical problems, the present embodiment provides a drying method of a laundry treatment apparatus, the drying method comprising:

[0040] determining whether the laundry in the laundry treatment drum is in a target load level;

[0043] The embodiment reflects whether the load in the drum is in light load or in very light load through the temperature rising parameter when the air inlet temperature of the drying process rising stage reaches the target temperature when the load level in the clothes treatment drum is in the target load level, so as to determine appropriate dry judgment strategies for light load and very light load, and avoid the problem of increasing energy consumption caused by too long drying time of very light load.

[0044] The technical solutions of the embodiment will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and examples can be combined with each other.

[0045] First, the implementation subject of the drying method of the embodiment is described in detail. The drying method of the embodiment is applied to a clothes treatment device, which can only have a drying function or can simultaneously have a washing function and a drying function.

[0046] The clothes treatment device includes a shell, an outer drum and a clothes treatment drum.

The drum wall of the outer drum is provided with an air outlet, the drum opening of the clothes treatment drum is provided with a door seal, the door seal is provided with an air inlet, and the drum wall of the clothes treatment drum is provided with a plurality of flow holes for the flow of air or water between the outer drum and the clothes treatment drum.

[0047] The clothes treatment device further includes an air duct assembly arranged in the space between the shell and the outer drum, preferably above the outer drum. The air duct assembly includes an air inlet duct, an air outlet duct and a fan. The air outlet duct communicates the air outlet with the air inlet end of the fan, and the air inlet duct communicates the air outlet of the fan with the air inlet.

[0048] The clothes treatment device further includes a heating device for heating the airflow in the air duct assembly. The heating device can be an electric heating device or a heat pump heating device. In an example, the heating device includes a compressor, an evaporator, a throttling device and a condenser. The compressor is arranged in the space between the shell and the outer drum, preferably at the bottom of the outer drum. The evaporator and the condenser are integrally arranged in a two-organ box body between the fan and the air inlet duct, and the condenser is arranged close to the air inlet duct. The compressor, the condenser, the throttling device and the evaporator are connected in sequence to form a refrigerant circulation loop.

[0049] The laundry treatment apparatus further comprises a first temperature detecting device and a second temperature detecting device, wherein the first temperature detecting device is configured to detect the inlet air temperature of the laundry treatment drum, preferably arranged at the inlet air port. The second temperature detecting device is configured to detect the outlet air temperature of the laundry treatment drum, preferably arranged at the outlet air port.

[0050] The drying method of the present embodiment will be described in detail below.

[0051] The present embodiment proposes a drying method of a laundry treatment apparatus, referring to the drying flow chart shown in FIG. 1, the drying method comprises the following steps: Figure 1

[0052] S11, determining whether the laundry in the laundry treatment drum is at a target load level.

[0053] In the present embodiment, before the laundry treatment apparatus enters the drying program, the load level of the laundry in the laundry treatment drum needs to be determined. Specifically, the weight of the laundry is determined first, and then the load level is determined according to the weight of the laundry. The weight of the laundry and the load level have a preset corresponding relationship, so that after the weight of the laundry is determined, the load level corresponding to the weight of the laundry can be determined. The weight of the laundry can be determined according to the weight parameter information input by the user, or according to the motor power value or current value when the laundry treatment drum rotates, or according to the eccentricity value when the laundry treatment drum rotates. After the load level of the laundry is determined, it is determined whether the load level is at a target load level.

[0054] Preferably, the target load level is a low load level, and the low load level is a load level corresponding to a small weight. Further preferably, the weight corresponding to the low load level is less than or equal to the minimum weight that the laundry treatment apparatus can hold. For example, the value range of the low load level is 0-1 kg.

[0055] S12, in the case that the load level of the laundry is at the target load level, obtaining the inlet air temperature of the laundry treatment drum in the heating stage of the drying program.

[0056] In the present embodiment, in the case that the load level is at the target load level, it is further determined whether the load is at a small load or an extremely small load, which can be determined by the heating condition of the laundry treatment apparatus in the drying stage. Specifically, the laundry treatment apparatus is controlled to enter the drying program, and the drying air flow is introduced into the laundry treatment drum to dry the laundry. As the drying continues, the inlet air temperature of the laundry treatment drum continues to rise, and the stage in which the inlet air temperature continues to rise is the heating stage. The inlet air temperature of the laundry treatment drum is obtained in the heating stage, so that the load condition in the drum can be further understood according to the heating condition of the inlet air temperature subsequently. In the case that the load level of the laundry is not at the target load level, the drying is performed according to the drying parameters corresponding to the load level. ​

[0057] S13, determine a temperature rising parameter of the temperature rising of the inlet air temperature to the target temperature, and determine a drying strategy of the drying stage according to the temperature rising parameter.

[0058] In this embodiment, the target temperature can be a temperature value corresponding to a middle stage of the temperature rising stage, or a temperature value corresponding to an end of the temperature rising stage. The temperature rising parameter of the temperature rising of the inlet air temperature to the target temperature reflects the load condition in the drum. The temperature rising parameter is, for example, a cumulative temperature rising time length and / or a temperature rising rate of the temperature rising of the inlet air temperature to the target temperature. Taking the cumulative temperature rising time length as an example, the longer the cumulative temperature rising time length is, the more the load in the drum is, and vice versa, the shorter the cumulative temperature rising time length is, the less the load in the drum is. Therefore, the temperature rising parameter of the temperature rising of the inlet air temperature to the target temperature can be used to distinguish whether the load in the drum is in the weight range of the small load and the extremely small load which cannot be distinguished by the weighing method, and then a suitable drying strategy is determined according to the comparison result of the temperature rising parameter.

[0059] In different drying strategies, the drying stage has different operation parameters and / or drying parameters, so as to avoid the problem that the extremely small load and the small load use the same operation parameters and / or drying parameters for drying, resulting in that the drying time of the extremely small load is too long and energy is wasted. In the case that the clothes treatment device includes a heat pump drying system, the operation parameter includes a compressor frequency; or, in the case that the clothes treatment device includes an electric heating system, the operation parameter includes an electric heating power.

[0060] In some embodiments, the method further includes determining a weight range of the clothes according to the temperature rising parameter. In an example, the temperature rising parameter includes a cumulative temperature rising time length of the temperature rising of the inlet air temperature to the target temperature, and determining the weight range of the clothes according to the temperature rising parameter includes determining the weight range of the clothes according to a comparison result of the cumulative temperature rising time length and a set temperature rising time length.

[0061] In this embodiment, since the time lengths of the temperature rising of the loads in different weight ranges from the initial temperature to the target temperature are different, the weight range of the clothes can be determined according to the comparison result of the cumulative temperature rising time length and the set temperature rising time length. The set temperature rising time length is a theoretical temperature rising time length of the load between two weight ranges from the initial temperature to the target temperature.

[0062] In the case that the cumulative temperature rising time length is greater than the set temperature rising time length, it indicates that the temperature rising time of the inlet air temperature from the initial temperature to the target temperature is relatively long, and the more the clothes to be dried, the more difficult it is to reach the target drying temperature. Therefore, it is determined that the weight range of the clothes is in the first weight range, and the first weight range is the small load range. For example, the weight value range of the first weight range is 0.5 kg < the first weight range ≤ 1 kg.

[0063] In a case that the accumulated temperature rising duration is less than or equal to the set temperature rising duration, it is indicated that the temperature rising time for the inlet air temperature to reach the target temperature from the initial temperature is short, and the less the drying clothes, the easier to reach the target drying temperature, and thus the weight interval of the clothes is determined to be the second weight interval, the second weight interval is the extremely small load interval, and the weight value of the first weight interval is greater than the weight value of the second weight interval. Exemplarily, the weight value of the second weight interval ranges from 0 to 0.5 kg.

[0064] In some embodiments, the temperature rising parameter includes an accumulated temperature rising duration for the inlet air temperature to rise to the target temperature, and the drying-out strategy of the drying-out stage is determined according to the temperature rising parameter, including: determining the drying-out strategy of the drying-out stage according to a comparison result of the accumulated temperature rising duration and the set temperature rising duration.

[0065] In an example, the drying-out strategy of the drying-out stage is determined according to a comparison result of the accumulated temperature rising duration and the set temperature rising duration, including: determining the drying-out strategy of the drying-out stage according to the weight interval in which the clothes is located.

[0066] Specifically, after the weight interval of the load is determined, the drying-out strategy of the drying-out stage is regulated according to the weight interval in which the load is located, for example, different weight intervals correspond to different drying-out parameters, and after the weight interval is determined, the drying-out is performed with the corresponding drying-out parameter in the drying-out stage.

[0067] For example, in a case that the drying-out parameter includes a compressor operating frequency, the smaller the weight value of the weight interval, the lower the compressor operating frequency corresponding to the weight interval, so that when the load level is determined to be the second weight interval, the drying-out can be performed with a lower compressor frequency, which reduces the compressor operating power while ensuring the drying effect, and accordingly reduces the overall energy consumption. When the load level is determined to be the first weight interval, the drying-out can be performed with a higher compressor frequency, which ensures the accuracy of the drying-out and ensures the drying effect.

[0068] In a case that the drying-out parameter includes the number of drying-outs, the drying-out parameter of the drying-out stage is regulated according to the weight interval in which the load is located, including: the smaller the weight value of the weight interval, the fewer the number of drying-outs corresponding to the weight interval, so that when the load level is determined to be the second weight interval, the drying-out can be performed with a smaller number of drying-outs, which further shortens the drying time while ensuring the drying effect, and is more energy-saving. When the load level is determined to be the first weight interval, the drying-out can be performed with a larger number of drying-outs, which ensures the accuracy of the drying-out and ensures the drying effect.

[0069] Exemplarily, in a case that the load level is determined to be the first weight interval, the subsequent drying-out process is performed with the compressor frequency and / or the number of drying-outs corresponding to the target load level; in a case that the load level is determined to be the second weight interval, the compressor operating frequency and / or the number of drying-outs are reduced on the basis of the compressor operating frequency and the number of drying-outs corresponding to the target load level

[0070] In another example, the running parameter includes a compressor running frequency; the determination of the drying judgment strategy of the drying judgment stage according to the comparison result of the accumulated temperature rising duration and the set temperature rising duration includes: in the case that the accumulated temperature rising duration is greater than the set temperature rising duration, determining to adopt a first compressor running frequency in the drying judgment stage; in the case that the accumulated temperature rising duration is less than or equal to the set temperature rising duration, determining to adopt a second compressor running frequency in the drying judgment stage; the second compressor running frequency is less than the first compressor running frequency.

[0071] In another example, the drying judgment parameter includes a drying judgment number; the determination of the drying judgment strategy of the drying judgment stage according to the comparison result of the accumulated temperature rising duration and the set temperature rising duration includes: in the case that the accumulated temperature rising duration is greater than the set temperature rising duration, determining to adopt a first drying judgment number in the drying judgment stage; in the case that the accumulated temperature rising duration is less than or equal to the set temperature rising duration, determining to adopt a second drying judgment number in the drying judgment stage; the second drying judgment number is less than the first drying judgment number.

[0072] In another example, the running parameter includes a compressor running frequency, and the drying judgment parameter includes a drying judgment number; the determination of the drying judgment strategy of the drying judgment stage according to the comparison result of the accumulated temperature rising duration and the set temperature rising duration includes: in the case that the accumulated temperature rising duration is greater than the set temperature rising duration, determining to adopt a first compressor running frequency and a first drying judgment number in the drying judgment stage; in the case that the accumulated temperature rising duration is less than or equal to the set temperature rising duration, determining to adopt a second compressor running frequency and a second drying judgment number in the drying judgment stage; the second compressor running frequency is less than the first compressor running frequency, and the first drying judgment number is less than the second drying judgment number.

[0073] In an optional implementation, the load level of the clothes is determined, including the following steps:

[0074] S21, before entering the drying program, entering a drying weighing stage.

[0075] S22, in the drying weighing stage, the clothes treatment drum is controlled to rotate, the eccentricity value of the clothes treatment drum is obtained, and when the eccentricity value of the clothes treatment drum reaches a preset weighing eccentricity value range, it is determined that the load level reaches a target load level according to the eccentricity value being greater than or equal to a set eccentricity value.

[0076] In this embodiment, before entering the drying program, the load level of the clothes needs to be determined. At this time, the drying weighing stage is entered, after entering the drying weighing stage, the clothes treatment drum is first controlled to rotate, and then the eccentricity value of the clothes treatment drum is detected. When the eccentricity value of the clothes treatment drum reaches a preset weighing eccentricity value range, at this time the clothes reach the wall sticking state, and the clothes treatment drum is in the balanced state and will not appear the situation of hitting the barrel.

[0077] Then the eccentricity value of the laundry treating drum in the balanced state is combined to determine the load level of the laundry. The eccentricity value range and the load level have a preset corresponding relationship in the balanced state of the laundry treating drum, and the greater the eccentricity value, the smaller the load weight of the load level corresponding to the eccentricity value range. Therefore, the eccentricity value of the laundry treating drum in the balanced state can determine the target load level. When the detected eccentricity value of the laundry treating drum is greater than or equal to the set eccentricity value, it indicates that the load level reaches the target load level, and the set eccentricity value is the eccentricity value corresponding to the minimum weight in the target load level.

[0078] In an implementable manner, the laundry treating apparatus is a washer-dryer, and the above-described drying weighing phase is performed after the dehydration phase of the washing program ends, and the drying program can be entered after the drying weighing phase ends.

[0079] The drying method of the embodiment will be described in detail below in combination with a specific example.

[0080] In combination with Figure 3 the drying flowchart, the drying method includes the following steps:

[0081] S31, after the dehydration phase of the washing program ends, entering the drying weighing phase;

[0082] S32, controlling the rotation of the laundry treating drum to obtain the eccentricity value of the laundry treating drum;

[0083] S33, judging whether the eccentricity value of the laundry treating drum is in a preset weighing eccentricity value range, if the result is yes, entering S34, and if the result is no, returning to S32;

[0084] S34, judging whether the eccentricity value is < a set eccentricity value X, if the result is yes, entering S35, and if the result is no, entering S36;

[0085] S35, determining that the load level of the laundry is not in the target load level, and running the drying according to the drying parameters corresponding to the load level;

[0086] S36, determining that the load level of the laundry is in the target load level, and recording the inlet air temperature T1 of the laundry treating drum in real time in the temperature rising phase of the drying program;

[0087] S37, judging whether the inlet air temperature T1 rises to a target temperature, if the result is yes, entering S38, and if the result is no, returning to S36;

[0088] S38, accumulating the temperature rising duration t rising;

[0089] S39, judging whether the accumulated temperature rising duration t rising is greater than a set temperature rising duration, if the result is yes, entering S310, and if the result is no, entering S311;

[0090] S310, determine the first weight interval, at this time, the subsequent dry judgment process is performed according to the compressor frequency corresponding to the target load level and the dry judgment times;

[0091] S311, determine the second weight interval, the weight value of the first weight interval is greater than the weight value of the second weight interval, at this time, the compressor operating frequency is reduced and the dry judgment times are reduced on the basis of the compressor operating frequency corresponding to the target load level and the dry judgment times.

[0092] In summary, in the case that the clothes to be dried are in the target load level, the weight interval of the clothes is determined according to the drying parameters when the inlet air temperature of the drying stage reaches the target temperature, so that it can be determined whether the clothes belong to light load or extremely light load, and then different dry judgment strategies are executed according to the determined weight interval in the dry judgment stage, so as to run according to different dry judgment parameters in different weight intervals, thereby avoiding the problems of too long dry time of extremely light load and increased energy consumption caused by using the same dry way for extremely light load and light load.
