After being cooled by the wall of the rear barrel, the wet air which is subjected to heat and mass transfer with the clothes in the roller is pumped into the inlet air duct 9 by the fan 8 through the air outlet pipe 6, the outlet air duct 7 and the corrugated pipe 13 to be heated, and then enters the front barrel 10 through the door seal 14 to be subjected to heat and mass transfer with the clothes in the barrel, so that primary circulation is completed.

In one embodiment, the clothes treating apparatus further comprises a spraying device 12, the spraying device 12 is disposed on one side of the filter screen 3 far away from the tub 1, and a flushing valve is disposed on the spraying device 12. This spray set 12 can set up on the lateral wall of export wind channel 7, can be through whether washing valve control spray set 12 works, when spray set 12 needs to wash filter screen 3, can open the washing valve, directly wash filter screen 3 from outside intaking, when need not washing filter screen 3, can close the washing valve.

The clothes treatment device also comprises other water inlet valves, and after the other water inlet valves are opened, the filter screen 3 cannot be washed by outside water.

Referring to fig. 1 to 6 in combination, according to an embodiment of the present application, a drum is disposed in a tub 1, and a control method of the laundry treatment apparatus includes: acquiring an operation program of the clothes treatment device; the cleaning mode of the filter screen 3 is selected according to the operation program of the clothes treatment device.

The operation program of the clothes treatment device comprises a washing program and a barrel self-cleaning program, one washing program comprises main washing and rinsing, rinsing can be selected for multiple times, two times of rinsing are defaulted in a common washing program, and the rinsing times can be selected by a user.

The bucket self-cleaning program is a program specially used for cleaning the bucket, and the bucket self-cleaning program requires a user to take out clothes, so that the problem of secondary pollution caused by lint is not needed to be considered when the filter screen is washed no matter in a main washing stage or a rinsing stage.

In one embodiment, referring to fig. 4 in combination, the step of selecting the cleaning mode of the filter net 3 according to the operation program of the laundry treatment apparatus includes:

at present, the washing program of the washing machine basically has 2 times of rinsing, and the filter screen is washed at the 1 st rinsing time, which is selected by the following considerations: the folding filter screen mode of the embodiment avoids the secondary pollution of the thread scraps as much as possible, the rotating speed of a user is approximately 50rmp in the washing process, the water flow brought by the rotation of the roller at the rotating speed cannot wash the filter screen, and the thread scraps cannot enter the roller; but the thread scraps must be treated, if not treated, the thread scraps block the air duct, and the drying function is affected; therefore, the washing brush filter screen is concentrated in the 1 st rinsing, the washed thread scraps are discharged through the 2 nd rinsing, and therefore the clothes can be prevented from being secondarily polluted by the thread scraps, and the clothes washing efficiency is improved.

Preferably, the water for the 1 st rinsing is all fed from the spray device, and the more water is flushed, the cleaner the rinsing is.

s3, washing the filter screen 3 with external water until the water level is set, and then jumping to S4;

s7: the drum runs at the rotating speed M for the remaining time and then is finished; wherein N1 < G1. The maximum time of the filter screen washing is t2, when the filter screen washing action is skipped, the washing machine runs at M speed, the speed is the default speed set by the program, and the general rinsing default speed is 50-60 rpm.

In this embodiment, t2 can be determined according to the rinsing time, if the rinsing time is longer, t2 is less than or equal to 30min, and if the rinsing time is shorter, t2 can be selected to be consistent with the default time. The default time is 1 rinse time, typically [5min, 30min ], preferably 8 min.

In one embodiment, referring to fig. 5 in combination, the step of selecting the cleaning mode of the filter net 3 according to the operation program of the laundry treatment apparatus includes:

s11: if the clothes processing device is in the barrel self-cleaning program, the program starts to run, a filter screen flushing command is executed, and S21 is skipped;

s21: washing the filter screen 3 with external water until the water level is set, and then jumping to S31;

s31: detecting whether the eccentricity OOB during the rotation of the roller meets the requirement of increasing the rotating speed of the roller, and if so, jumping to S41; if not, jumping to S51; the forced high rotation speed without the OOB limit condition may cause the washing machine to collide with the drum to be displaced, and thus, the safe and reliable operation of the washing machine may be ensured by the above-mentioned limit.

S41: rotating the roller at the rotating speed G for ti time, and rotating to S31; the operation is switched to S61 until the operation time is accumulated to t 1;

s51: rotating the roller at the rotating speed N for ti time, and then rotating to S31; the operation is switched to S61 until the operation time is accumulated to t 1;

In one embodiment, referring to fig. 6 in combination, the step of flushing the filter net 3 with the external water includes:

s22: opening a flushing valve, flushing the filter screen 3 through the spraying device 12, and jumping to S32 after water inlet time t 3;

In one embodiment, t3 < t2 < t1, and t3 is less than or equal to 3min, it is required to ensure that most of the lint can be washed away and removed to the outside of the laundry treatment apparatus when the filter net 3 is washed by the outside water sprayed by the spraying device 12, and the cleaning effect of the filter net 3 is ensured.

In one embodiment, N = N1 is a swing rotation speed, wherein the rotation speed is set within a range of 30 rpm to 50 rpm. The drum rotates for several times at the rotating speed N, the clothes can be paved again, the clothes are prevented from being agglomerated, and the OOB value is reduced; the more even the clothes in the drum are, the smaller the OOB value is, and the washing machine can rotate at a high speed; therefore, N is called the swing rotation speed.

In one embodiment, G1 < G, when the self-cleaning program of the barrel is executed, the rotating speed can be properly increased because the drum is not provided with clothes, thereby ensuring the height and the washing force of the water flow and ensuring the cleaning effect of the filter screen 3. In one embodiment, G is more than or equal to 120r/min and less than or equal to 200r/min, G is more than or equal to 80 r/min and less than or equal to 1 and less than or equal to 120 r/min.

By the control method of the clothes treatment device, the filter screen 3 can be automatically cleaned by selecting a proper time node, so that the cleaning effect is good, secondary pollution to clothes can be avoided, and the use experience of a user is effectively improved.

It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
