Definitions

  • the present invention generally relates to filtration systems developed for use in laundry drying machines. More particularly, the present invention relates to a combined filter structure consisting of inner and outer filters with different pore structures, which are placed in the door region of the drying machine.
  • the laundry drying machines comprise filtering systems, which are placed on the front bearing in the door area and positioned in the air passage channel in front of the heat exchangers. Said filtration systems are combined in many products and attached to the front bearing in the door area.
  • the combined filters have different pore structures and are composed of two different parts, inner and outer filters.
  • a combined filter structure comprising an inner filter which is placed into an outer filter.
  • the inner and outer filter structures are configured so as to move axially around the separate hinge elements.
  • a drying machine comprising an air filtration cartridge having a first and a second air filtration body in the form of a bag or pocket, shaped so as to be inserted into the air duct, constructed to trap fluff and lint particles in the air.
  • said first air filtration body is slid into said second air filtration body by being moved along a lateral movement axis perpendicular to the movement axis of the first air filtration body into the air duct, thus forming the outer and inner filter structures.
  • a combined filter structure which is placed into an opening on the body of the drying machine and which is composed of an inner filter and an outer filter which are nested into each other.
  • said filter structure it is mentioned that there is a main filter operating in the circulation air that enters through the circulation air inlet port of the filtration receptacle and discharged from the circulation air discharge port, and a support filter that works together with the same. Since the support filter is inserted and removed before the main filter, and the main filter is inserted after the support filter and removed before the same, the main filter is removed independently, thus leaving the support filter in the receptacle thereof to handle the clogging.
  • the aim of the present invention is the realization of a filter assembly which can be used in laundry drying machines.
  • Another aim of the present invention is the realization of a filter assembly which is composed of an inner and an outer filter structure to be used in the laundry drying machines.
  • Yet another aim of the present invention is the realization of a filter assembly which is composed of an inner and an outer filter structure to be used in the laundry drying machines, as well as a handle cover.
  • Another aim of the present invention is the realization of a combined filter assembly structure wherein an inner and an outer filter structure as well as a handle cover can be grouped together to be used in the laundry drying machines.
  • the combined filter system of the present invention proposes solutions to problems in the prior art.
  • the user is enabled to remove said filter in a in a single step instead of multiple separate steps which may be caused by the multi-part configuration of the combined structure,
  • the outer filter is prevented from falling by means of the ribs extending from the handle to the body, thus preventing the outer filter from leaving the housing and scattering the lint therein.
  • connection-joint members that can be positioned on either of said parts.
  • said connection-joint parts may also be included in a handle cover, apart from the inner filter and the outer filter.
  • said filter assembly when mounted in the laundry drying machine, is configured in such a way that in the grouped state, the outer filter must be removed first.
  • a laundry drying machine comprises the combined filter of the present invention.
  • this document relates to a new filter assembly that exceeds the limitations of state of the art filtration assemblies by providing an especially compact design, comprising an inner and an outer filter, while the size of the filtration holes can be adjusted according to different embodiments.
  • the present invention relates to a combined filter assembly (10) which is placed on the front bearing in the door area in the laundry drying machines and positioned in the air passage channel in front of the heat exchangers.
  • the proposed filter assembly (10) comprises an inner filter (11) and an outer filter (12). Said inner filter (11) and said outer filter (12) are arranged one inside the other towards the center of the combined filter structure, and the inner filter (11) body can be fitted in the outer filter (12) body at least up to a sufficient height.
  • said inner filter (11) body is in a structure that corresponds to said outer filter (12) body in terms of external frame, and can be fitted into said outer filter (12) body with a rail mechanism provided on the vertical axis.
  • Said inner filter (11) and said external filter (12) in the proposed filter assembly (10) may have different pore sizes.
  • the outer filter (12) can be configured to filter lint of a certain size, while the inner filter (11) can be configured to filter lint of another certain size.
  • a handle cover (13) is proposed in addition to said inner filter (11) and said outer filter (12) structures.
  • Said handle cover (13) is configured to form the combined filter structure of the present invention by being grouped together with said inner filter (11) and said outer filter (12) structures.
  • a structural relationship is established between said inner filter (11) and said outer filter (12) structures so as to attach said structures to each other while including a locking mechanism to maintain this relationship.
  • Said inner filter (11) and said outer filter (12) structures, which are locked to each other, cannot be separated from each other without physical intervention on the handle cover (13).
  • said handle cover (13) comprises at least one surface, hereinafter referred to as the first surface, in the functionally positioned state of the filter assembly (10), in other words attached to a laundry drying machine.
  • Said handle cover (13) further comprises a second surface corresponding to the horizontally axially opposite surface of the first surface.
  • Said first surface is surrounded by the outer wall of the inner filter (11) and defines an operationally locked, that is grouped, inner volume.
  • Said inner volume comprises two gaps (16) which receive two claws (15) defined to enter the inner filter (11) body.
  • Said two gaps (16) are configured to be wide enough to receive two ribs (17) which extend from said first surface along the axis of the two claws (15) in the opposite direction to the claws (15) and leave the inner volume from a point close to the said claws (15).
  • the locking mechanism (14) obtained with the handle cover (13) is operated as follows: The spacing provided by each of said two gaps (16) is large enough to receive at least one rib (17) and at least one claw (15). Thus, if said rib (17) is not removed and a sufficient amount of space is not provided, the sloping and outer-facing protrusions of the claws (15) make it impossible for the inner filter (11) to move away from said handle cover (13). Thus, the locking mechanism (14) prevents the removal of the inner filter (11) structure without prior physical intervention on the outer filter (12) body for the purpose of removal.
  • a combined filter assembly (10) is realized, suitable to be used in a laundry drying machine, comprising a grouped inner filter (11) and outer filter (12) structure.
  • said outer filter (12) structure is located on the outside of the combined filter assembly (10) and is configured to contain said inner filter (11) structure in a large amount by volume.
  • said inner filter (11) structure is designed and configured so as to be removed only after the outer filter (12) is removed, in accordance with the structure of the combined filter assembly (10).
  • said combined filter assembly (10) comprises a locked handle cover (13) during operation, which create a temporary structural relationship between the inner and outer filters (11, 12) so as to prevent the outer filter (12) from falling when the inner filter (11) is opened.
  • said handle cover (13) comprises two ribs (17) which extend towards the inner filter (11) in the locked position and are configured to provide sufficient horizontal clearance for said two claws (15) to flex without being released.
