Description

Treatment module for a laundry treatment apparatus, laundry treatment apparatus and method for operating a laundry treatment apparatus Technical Field The invention relates to a treatment module for a laundry treatment apparatus, comprising a plurality of treatment brushes, which are each provided for contacting laundry to be treated. The invention further relates to a laundry treatment apparatus having the aforementioned treatment module, and also to a method for operating a laundry treatment apparatus. Background In particular, a laundry treatment apparatus is disclosed in which laundry is generally individually suspended and subjected to a corresponding treatment. In this case, in devices of this type and in some cases also referred to as laundry treatment cabinets, a movable treatment module is often provided, with which the respective treatment of the introduced laundry takes place in at least one treatment step. In this case, a treatment module of this type may have a treatment brush which is brought into contact with the incoming laundry during the treatment step in order to smooth out the latter. WO 2020/084315 A1 discloses a laundry treatment apparatus configured as a laundry treatment cabinet having a treatment chamber into which laundry to be treated can be individually introduced. Furthermore, a treatment module is provided in the treatment chamber of the laundry treatment apparatus, which is vertically movable in the treatment chamber and has a flexible steam head. The laundry to be treated is spread out in the treatment chamber to be smoothed, wherein the steam head of the treatment module is brought into contact with the laundry during the treatment. Further, treatment brushes are provided on opposite sides of the steam head, each treatment brush being in contact with the side of the laundry during treatment of the laundry. Disclosure of Invention Starting from the above-described prior art, it is now the object of the present invention to provide a treatment module for a laundry treatment apparatus, with which wrinkles/folds of laundry introduced into the laundry treatment apparatus can be removed as much as possible within the framework of the smoothing process. The object is achieved by the features of the solution according to the invention. The technical scheme reflects the advantageous development of the invention respectively. Further, a laundry treatment apparatus to which the treatment module of the present invention is applied is the subject of the present invention. The invention further relates to a method for operating a laundry treatment device. According to the invention, the treatment module comprises a plurality of treatment brushes, each for contacting the laundry to be treated. The treatment module according to the invention is intended for use in a laundry treatment apparatus in order to smooth laundry introduced into a treatment chamber as comprehensively as possible in the treatment chamber and during the smoothing process by means of a treatment brush. In the sense of the present invention, a treatment brush relates to components of a treatment module which, during the treatment of the laundry to be treated, are brought into contact with the laundry at the bristles or bristle-like projecting elements in order to introduce mechanical stresses into the laundry, thereby at least partially reducing wrinkles/folds. The bristles or bristle-like elements are preferably made of an elastic plastic material. The treatment module is preferably configured to be movably accommodated in the laundry treatment apparatus in order to effect at least one movement of the treatment module along the laundry to be treated during contact of the treatment brush with the laundry and to effect a smoothing of the laundry therein. For this purpose, in particular, on the side of the treatment module, a respective guide is provided, by means of which the treatment module is guided in the mounted state in a respective guide device of the laundry treatment device in order to present a guided movement in the laundry treatment device. It is further preferred that one or more drive means are provided on the processing module side, by means of which drive means a drive motion can be transmitted to the drive module. The invention now includes the technical teaching that every two treatment brushes form at least one pair and are arranged here with respect to one another in a treatment position or can be arranged in a treatment position in which the at least one pair of treatment brushes are opposite one another in such a way that they come into contact with the laundry on both sides when the laundry is placed between the at least one pair of treatment brushes. In other words, in the process module of the present invention, at least one pair is provided, which is composed of two process brushes, respectively. In the treatment position of the at least one pair of treatment brushes, the treatment brushes are po
