Method for controlling a fabric treatment appliance, fabric treatment appliance and computer program product Technical Field The present application relates to the field of household appliances, in particular to a method for controlling a fabric treatment appliance, and a computer program product for at least assisted implementation of the steps of the method according to the present application. Background In the existing fabric treatment apparatuses having a drying function such as a clothes dryer, a drying and washing integrated machine, etc., generally an air inlet is provided at a rear drum wall and an air outlet is provided at a filter screen below a machine door, most of hot air is blown to the filter screen during drying, and the air volume of the fabric treatment apparatus is large and the air velocity is high, so that small lightweight fabrics such as scarves, socks, infant clothes, etc. are easily adsorbed near the filter screen, which not only causes the fabrics to continuously contact with a humidity sensor near the filter screen, thereby causing deviation of control parameters of the drying process, but also causes serious wrinkles of the fabrics, especially, a part of the fabrics of normal size such as scarves but very light and thin may be piled up near the filter screen, while the rest may still rotate in a drum, which may cause wrinkles, wear and snagging of the fabrics. Furthermore, the fabric that is deposited at the screen below the gate is also very noticeable to the user, which will greatly affect the user experience of the fabric treatment appliance. Therefore, effectively preventing small pieces of fabric from being adsorbed during the fabric drying process is a technical problem to be solved at present.

By circularly executing the steps S1 to S3, the switching of the rotation direction of the drum can be realized, so that the fabric is continuously turned over in the fabric drying process, and the fabric is ensured to be sufficiently dried. According to another alternative embodiment of the application, the direction of rotation of the drum may be switched a plurality of times, and the drum is rotated for a first desired period of time between the two switches.
