[0124] If it is judged that the collection box is cleaned, the drying time and the drying number of the present drying are cleared after the drying is ended.

[0125] If it is judged that the collection box is not cleaned, the drying time and the drying number of the present drying are added to the acquired accumulated drying time and accumulated drying number after the drying is ended.

[0126] In any of the above embodiments, the method further comprises the following steps:

[0127] After starting drying, the drying time tn in the current drying process is acquired, and the acquired drying time tn is compared with the preset drying time T2.

[0128] If the drying time tn reaches the preset drying time T2, the cleaning rod is controlled to rotate.

[0129] In any of the above embodiments, the method further comprises the following steps:

[0130] An activation instruction of the laundry treatment apparatus is acquired, a current position of the cleaning rod is acquired, and the cleaning rod is controlled to be in a position not to open the upper cover of the collection box.

[0131] The following will be described in combination with Figures 1-11 The working mode of the laundry treatment apparatus will be described in detail, taking a clothes dryer as an example.

[0132] When the user activates the clothes dryer, the control system detects the current position of the cleaning assembly 4 through the motor and controls it to be in a position not to open the upper cover 32 of the collection box. Then, the current accumulated drying number na and accumulated drying time ta since the last cleaning of the lint collection box are read, and are compared with the set drying number threshold N and drying time T. If the current accumulated drying number na is greater than the threshold N, the user is reminded to dump the lint in the collection box 31; if the current accumulated drying number na is less than the threshold N, it is determined whether the current accumulated drying time ta is greater than the threshold T. If yes, the user is reminded to dump the lint in the collection box 31; if no, the drying is started. During the drying process, the drying time tn in the current drying process is acquired. If tn reaches a certain value T2, the motor 5 is driven to rotate, and the filter screen self-cleaning and lint automatic collection functions are started.

[0133] During the drying process, the dry warm air enters the laundry treatment drum 61, taking the moisture on the clothes, and enters the door body 1. The warm air first passes through the door body air inlet 12 on the outer surface of the door shell, blocking the clothes and small parts on the clothes from entering the door body 1. When the warm air enters the door body 1, it will directly pass through the filter screen 21, and the lint carried by the warm air will be blocked by the filter screen 21, and the lint will be adsorbed on the filter screen 21. The filtered warm air will flow downward in the door body 1 and flow to the heat pump device 7, and then be dried.

[0134] After a period of drying, the self-cleaning program is started, the motor 5 drives the cleaning assembly 4 to rotate, the elastic cleaning brush 41 on the cleaning assembly 4 close to the filter screen 21 rubs against the filter screen 21, and the lint on the filter screen 21 is scraped off. When a certain amount of lint is scraped off and the cleaning assembly 4 rotates to a certain angle, the lint will fall near the collection box upper cover 32 below the cleaning assembly 4. When the cleaning assembly rotates to open the collection box upper cover 32, the lint will be blown into the lint collection box 31 under the action of the warm air and gravity, and the automatic lint collection process is completed.

[0135] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content with the prompt as equivalent embodiments of equivalent changes without departing from the technical solution of the present application. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, which does not depart from the technical solution of the present application, still belongs to the scope of the present application.
