Description

Washing article treating device

Technical Field

The invention relates to a laundry treatment appliance, in particular a laundry dryer, having at least one filter insert receptacle and having at least one filter insert inserted into the filter insert receptacle, the filter insert having at least one dimensionally stable retaining member and at least one filter pocket retained by the retaining member, the retaining member having at least one air inlet, wherein the retaining member can be connected to the filter pocket without damage, wherein the filter insert is designed such that it can be inserted as a whole into the filter insert receptacle and can be removed as a whole from the filter insert receptacle.

Background

The laundry dryer comprises a process air circulation system in which drying air is circulated during the drying process. The drying air is guided through a receptacle in which a washing drum containing the laundry to be dried is rotatably arranged, which receptacle forms part of a process air circulation system. The washing drum is rotated during the drying process, thereby moving the laundry present in the washing drum. In this case, in particular the fluff and the hair are detached from the laundry and carried along by the drying air. In order to prevent such contaminants of the drying air from being introduced into the container or the washing drum again in the process air circulation system, it is known to filter the contaminants out of the drying air by means of a filter. If the laundry dryer has a heat pump which is thermally coupled to the process air circulation system, it can be achieved by filtering the drying air that the heat exchanger of the heat pump is not contaminated and contaminated, which can lead to a reduction in the efficiency of the heat pump.

DE 102014105327 a1 relates to a laundry dryer having a drum which is mounted rotatably in a housing, a loading opening which can be closed by a door, and a device for generating a process air flow which flows through an air guide between an intake drum and a heat exchanger as a flow channel. The inlet of the air guide is arranged in the curved region of the loading opening. The fluff is filtered in the air guide by means of a bag. A flap part can be inserted over the bag, which flap part, in the inserted state, forms a detachable connection with the bag inserted into the air guide. The bag is first loaded into an air-directing device. The flip is then loaded.

EP 2492389 a1 relates to a laundry dryer having a washing drum, a door which can close the washing drum, a fluff filter device in an air channel of an air circulation system which extends through the washing drum for blocking at least a portion of the laundry fluff which is entrained in the process air. The fluff filter device contains at least one filter bag having a bag opening and a bag lumen. The filter bag is arranged on the door of the washing dryer.

Disclosure of Invention

The aim of the invention is to reduce the maintenance costs for operating a laundry treatment appliance.

This object is achieved by the laundry treatment appliance according to the invention. Advantageous, optional configurations are given in the following description and the drawings, wherein said configurations can each alone or in different combinations with one another achieve further improved, in particular also preferred or advantageous, aspects of the invention.

The laundry treatment appliance according to the invention, in particular a laundry dryer, has at least one filter insert receptacle and at least one filter insert inserted into the filter insert receptacle, the filter insert having at least one dimensionally stable retaining member and at least one filter bag retained by the retaining member, the retaining member having at least one air inlet, wherein the retaining member can be connected to the filter bag without damage, wherein the filter insert is designed such that it can be inserted as a whole into the filter insert receptacle and can be removed as a whole from the filter insert receptacle, wherein the filter bag has at least one closure unit for closing the air inlet of the filter bag.

According to the invention, the filter insert can be inserted as a whole into the filter insert receiving portion and removed as a whole from the filter insert receiving portion. The filter bag can therefore be handled by the retaining means and thus reliably prevents the user of the laundry treatment appliance from coming into contact with the filter bag which is contaminated after use when inserting and removing the filter insert. Furthermore, the handling of the filter insert according to the invention is simplified in comparison with the filter known from DE 102014105327 a1, in which the filter bag and the flap have to be inserted separately from one another. The maintenance costs for operating the laundry treatment appliance according to the invention are therefore reduced.

Conventional filter inserts, for example in the form of fluff screens, can be replaced by filter inserts according to the invention. In this case, the filter insert receptacle is arranged on a section of the process air circulation system of the laundry treatment appliance, wherein this section can be arranged in the lower region of the loading opening, in particular on a front support panel of the laundry treatment appliance. The filter insert according to the invention can be used for filtering process air or drying air during a conventional drying process and/or during a specific program, which may be a time program. The filter insert can be designed to filter out different particles, such as fluff, pollen, hair, animal dander, allergen particles and the like, from the process air, which are detached from the laundry when the laundry is moved in the washing drum of the laundry treatment appliance.

By closing the closing unit, leakage of particles from the filter bag into the surroundings can be prevented during cleaning and/or intermediate storage of the used filter bag, which can be disadvantageous in particular with regard to allergen particles. The closing unit may be configured such that it is opened by a user before arranging the filter bag on the retaining member and closed after detaching the filter bag from the retaining member. Alternatively, the closing unit may be configured such that it is forcibly opened before the filter bag is arranged on the retaining member and forcibly closed after the filter bag is detached from the retaining member, without having to be handled by the user here. That is to say, the automatic opening of the closure unit can take place by placing the filter bag on the retaining member, by inserting the filter insert into the filter insert receptacle or by the volumetric flow of process air or drying air within the laundry treatment appliance. The closing of the closing unit can accordingly take place by detaching the filter bag from the retaining member, by removing the filter insert from the filter insert receptacle or by shutting off the volumetric flow of process air or drying air within the laundry treatment appliance. The closing unit can have a filter bag frame arranged on the filter bag, which is designed to be articulated in multiple ways, and which can be designed in its open state, for example, hexagonally or parallelogram-shaped. The closing unit can be opened and closed by planar deformation of the filter bag frame. Alternatively, the closing unit can be designed such that the filter bag with the filter bag frame can be closed not in a plane but three-dimensionally. For this purpose, the filter bag frame can have at least two frame elements which are connected to one another in an articulated manner.

The retaining member may be partially or completely manufactured from plastic, metal or composite material. The retaining member can be supported on a member of the laundry treating appliance adjoining the filter insert receiving portion and thereby carry a filter bag, by means of which a corresponding support cannot be achieved due to its flexibility. The retaining member is preferably constructed such that it can be used throughout the entire service life of the laundry treatment appliance. If the filter insert receptacle is arranged at a front support guard well of the process air circulation system of the laundry treatment appliance, the retaining member can additionally have the function of preventing laundry from falling into the support guard well or reaching the filter bag. Furthermore, the retaining member is preferably designed such that it constitutes as little flow resistance as possible for the process air volume flow.

The filter bag may be a disposable component which is removed after a shorter service life than the retaining member and replaced by a new, clean filter bag. Alternatively, the filter bag can be a multi-use component which is cleaned and reused at certain time intervals or depending on its degree of contamination.

According to one advantageous embodiment, at least one actuating element is arranged on the filter insert. The user can insert the filter insert into the filter insert receptacle or remove it by means of the actuating element without coming into contact with the remaining filter insert, in particular the filter bag. The actuating element can be arranged on the holding member and can be configured, for example, as a grip, a cleat, a strap, a bail or the like.

According to a further advantageous embodiment, at least one first connection piece is arranged on the retaining member and at least one second connection piece is arranged on the filter bag, wherein the connection pieces are designed such that they can be connected to one another without damage only by means of a linear relative movement between the retaining member and the filter bag. The connecting elements can be designed, for example, as latching hooks or latching tongues which engage with one another. Alternatively, the connection piece can, for example, form a groove-and-tongue system or a dovetail connection, wherein the groove is arranged on the retaining element or on the filter bag. In a linear relative movement or linear engagement direction (horizontal), the tongue or dovetail can optionally be pushed into the groove or dovetail groove via the narrow side of the filter insert or via the wide side of the filter insert. Furthermore, at least one locking flap is arranged on the retaining member, which in its closed position, secured on the retaining member, prevents the tongue engaged in the groove from sliding out of the groove.

According to a further advantageous embodiment, at least one first connection element is arranged on the retaining member and at least one second connection element is arranged on the filter bag, wherein the connection elements are designed such that they can be connected to one another without damage by at least two different relative movements between the retaining member and the filter bag. For example, the first connection can have at least one movably arranged flap, the pivot point of which is arranged on the upper section of the holding member facing away from the filter bag or on the lower section of the holding member, and which performs a pivoting movement as a relative movement. Alternatively, the connection piece can form a plug-and-turn arrangement in which the second connection piece has a turning hook arranged on the filter bag and the first connection piece has a receptacle for the turning hook. The rotating hook and the receiving portion may be configured such that the rotating hook can be engaged into the receiving portion from inside or from outside. After engaging the rotating hook to the receiving portion, the filter bag can be swung relative to the retaining member, whereby the filter bag edge adjoining the air inlet of the filter bag is introduced into the retaining member. In this case, the detent connection or the like can be locked, so that the filter bag can be connected to the retaining element without damage. Alternatively, the connector forms a bayonet connection. Alternatively, the second connection member is connected to the first connection member by at least partially unfolding the filter bag. For example, the filter bag can be actively clamped by the user against the holding element. Alternatively, the filter bag can be in a form of passively or automatically clamping the filter bag on the retaining member. Alternatively, a wrap-around contact solution is possible, in which the filter bag is fixed to the retaining member in such a way that the filter bag is pivotably supported on the retaining member by means of a latching pivot hook on one side of the filter insert and is fixed, for example latched, to the retaining member by means of multiple hinged tabs on the opposite side of the filter insert. The tab can be constructed in the form of a hook and loop. The tab may also form an actuating element, for example a gripper, for actuating the filter insert.

According to a further advantageous embodiment, the connecting element forms a force-fitting connection. For example, the filter bag can have, adjacent to its air inlet, an elastic bag edge with or without rubber ribs or the like, wherein the bag edge for placing the filter bag on the retaining member is elastically deformed and, after unloading, automatically transforms into its unloaded shape in which it cooperates with a groove or the like provided for this purpose on the retaining member. The detachment of the filter bag from the retaining member can accordingly be achieved by elastic deformation of the bag edge. Alternatively, a force-fitting connection may be achieved by a conical connection between the retaining member and the filter bag.

According to a further advantageous embodiment, the connecting element forms a form-fitting connection.

According to a further advantageous embodiment, the closing unit comprises at least one elastic diaphragm, on which at least one opening is formed which is closed in the unloaded state of the diaphragm. The opening can be at least partially slot-shaped and have at least partially a linearly, zigzag or otherwise shaped extension. The membrane is at least partially made of an elastic material, in particular an elastomer. The opening of the membrane is closed, for example automatically, when the opening is no longer flowed through by process air and is pressed in this case, or when the section of the retaining member no longer holds the membrane open, or when the membrane is closed by removing the retaining member from the filter bag. The advantage of this solution is to resist possible "loss of elasticity" or fatigue of the membrane. The possibility arises that the diaphragm will no longer close properly due to fatigue of the diaphragm. If the membrane is of bistable design, it is pulled into a stable position by the retaining member by a movement directed away from the filter bag when the retaining member is removed from the filter bag, so that it can be reliably closed. The membrane may have multiple layers or layers of different strengths. The membrane can be realized by a section of the filter bag, i.e. also by the filter material, so that the closure of the filter bag is realized by the filter material itself of the filter bag. The closed cell may have one, two or more membranes.

According to a further advantageous embodiment, the closing unit has at least one frame and at least one flap movably arranged on the frame, the frame having at least one opening, the flap closing the opening in the closed state and at least partially opening the opening in the open state. The movement of the flap from its closed position into its open position can be effected, for example, by means of a mechanical or magnetic actuator. The frame can be constructed by the holding member itself or as a separately manufactured member arranged on the holding member. The flap can, for example, be produced separately and connected to the frame by at least one hinge after its production. The flap and/or the frame may be manufactured as an injection molded part. The flap may be connected to the frame, for example, by at least one film hinge, wherein the flap may be produced as a single injection-molded part together with the frame and the film hinge. The axis of rotation of the flap can be arranged on the long side of the filter insert or on the short side of the filter insert. The return of the flap into its closed position can be effected by means of at least one spring element or by preloading the flap itself. The closure unit may have one, two or more flaps.

According to a further advantageous configuration, the closing unit comprises at least one louver. The louver may be closed and opened in a longitudinal direction or a lateral direction of the filter insert. The shutter may automatically close the filter bag when the filter insert is removed from the filter insert receptacle. Alternatively, the louvers may automatically close the filter bag when the retaining member is removed from the filter bag. Alternatively, the louvers may be manually closed by the user. The blind can have a handle for opening and closing, respectively, wherein the handle can be arranged on mutually opposite sections of the blind. The closed unit may have one, two or more louvers.

According to a further advantageous embodiment, at least one marking is present in the region of the filter insert receiver and on the filter insert, wherein the marking indicates a defined positioning of the filter insert relative to the filter insert receiver. This reliably prevents the possibility of incorrect installation by the user. The marking can be embodied stereoscopically and/or as a color marking. The indicia on the filter insert may be disposed on the retaining member and/or on the filter bag.

According to a further advantageous embodiment, the filter insert has at least one contact protection element, which at least partially surrounds the filter bag. This prevents the filter bag from being touched during handling of the filter insert, to be precise independently of the respective connection principle between the filter bag and the retaining element. The contact protection unit may have a protective grid structure at least in part.

The invention is not limited to a given combination of features of the disclosure. Further possibilities of combinations of the individual features with one another are thus to be found when the individual features are to be derived from the following description of a particularly preferred embodiment or directly from the drawing.
