Definitions

  • the invention relates to a front-loading washing machine and a method for producing a door seal.
  • a front loadable washing machine comprising a washing machine housing with a housing front, a tub arranged in the washing machine housing, a drum arranged rotatably in the tub, a loading opening arranged in the front of the housing, which can be closed with a door is, a circumferential door seal extending between the front of the housing and the tub around the loading opening, which connects the front of the housing and the tub in a liquid-tight manner, and a drum lighting with a drum lighting housing that is integrated into the door seal.
  • Such a washing machine is known from a prior art that is not documented in printed documents, in which a cylinder-shaped drum lighting housing is pushed somewhat oversized into a socket of the door seal.
  • a diameter of the drum lighting housing is larger than an inner diameter of the connecting piece.
  • the drum lighting is fixed and a sealing effect is achieved.
  • the drum lighting housing must have a sufficiently round cross-section, and the connecting piece and the drum lighting housing must have a minimum contact surface, which is reached when the connecting piece and the drum lighting housing are at least 20 mm high. This requirement can only be met if a circumferential fold of the door seal is reduced in size in this area compared to a door seal without drum lighting.
  • the invention thus has the problem of providing an automatic washing machine with a door seal with integrated drum lighting and a method for producing the door seal, with which a mechanical and economic improvement is provided.
  • the advantages that can be achieved with the invention consist, in addition to a mechanical and economic improvement, in a thermal and optical improvement of the door seal including drum lighting.
  • the door seal is tightly connected to the drum lighting housing.
  • the tightness achieved between the door seal and the drum lighting housing is independent of a geometry and / or a cross section of the drum lighting housing.
  • the door seal has at least one door seal connecting section which is positively connected to the drum lighting housing.
  • the drum lighting housing preferably has a height that is less than 20 mm, more preferably in the range from 3 to 15 mm, even more preferably in the range from 5 to 7 mm.
  • the drum lighting housing is preferably transparent.
  • the drum lighting housing is preferably designed as a lens housing.
  • the drum lighting housing preferably has a predetermined part which is positively connected to the door seal connecting section.
  • the drum lighting housing is encapsulated by the at least one door seal connecting section.
  • the drum lighting housing is preferably encapsulated by the at least one door seal connecting section in such a way that the predetermined part is positively connected to the door seal connecting section.
  • the drum lighting housing is placed in a tool for producing the door seal and overmolded. This creates at least one positive connection between the door seal connecting section and the predetermined part of the drum lighting housing.
  • the drum lighting housing is injected into the at least one door seal connecting section.
  • the drum lighting housing is preferably injected into the at least one door seal connection section in such a way that the predetermined part is positively connected to the door seal connection section.
  • the door seal including the integrated drum lighting can be produced using a 2K (2-component) technique, for example.
  • One component comprises a material for the door seal and the other component comprises a further material for the drum lighting housing.
  • the further material for the drum lighting housing is injected into the material of the door seal in a predetermined area.
  • the drum lighting housing preferably has one or more undercuts in which one of the at least one door seal connecting section is or are arranged.
  • the drum lighting housing has one or more holes in which one of the at least one door seal connecting section is or are arranged.
  • the drum lighting housing has one or more projections which is or are each arranged in one of the at least one door seal connecting sections. The projection can be designed, for example, as a circumferential projection of the drum lighting housing.
  • the lens housing has at least one or more cutouts in which one of the at least one door seal connecting section is arranged.
  • a connection between the door seal and the drum lighting housing can be further improved.
  • the drum lighting housing when the drum lighting housing is placed in a tool for producing the door seal and encapsulated, the material of the door seal can flow into the at least one undercut and / or into the at least one hole.
  • the drum lighting housing has a circumferential projection which has one or more undercuts and / or holes.
  • the projection or projections can each have a T-shape, for example. This will continue to support the connection.
  • the door seal preferably has a round cross-sectional shape so that it is designed as a door seal.
  • the door seal has a fold which is arranged circumferentially around the door seal, which is designed around. This improves the unbalance absorption and the service life of the washing machine.
  • the fold In comparison to a correspondingly comparable door seal without drum lighting, the fold is the same size or essentially the same size. That is, if a door seal has the same dimensions and is designed in the same shape with and without drum lighting, the fold has the same or essentially the same shape and dimensions regardless of whether the door seal has the drum lighting or not.
  • the drum lighting preferably has a light source which is arranged in the drum lighting housing and which is designed as one or more LEDs. LEDs are long-lasting and inexpensive light sources.
  • the drum lighting has a circuit board with cooling surfaces, which is arranged in the drum lighting housing and on which the light source is arranged.
  • the cooling surfaces show that the heat generated by the operation of the light source is dissipated. Sufficient dimensioning of the board and the cooling surfaces is an economical solution for this.
  • the cross section of the board can have any shape.
  • the geometry of the circuit board can be freely selected since the tightness between the drum seal and the drum lighting housing is independent of the cross section and / or the geometry of the drum lighting housing.
  • the board preferably has a circular or round, oval, rectangular or trapezoidal cross section.
  • the board more preferably has the oval or rectangular cross section.
  • the available installation space can be optimally used by choosing the geometry.
  • a drum lighting housing material has a Shore hardness and a door seal material has a further Shore hardness, the quotient of which is in the range from 0.5 to 1.5, more preferably 0.8 to 1.2, more preferably 0.9 to 1.1.
  • a mechanical and / or thermal improvement is also achieved.
  • the drum lighting housing is preferably made of optical silicone. This is a comparatively soft material. Alternatively or additionally, the drum lighting housing is made of polymethylpentene. This is a comparatively hard material.
  • the drum lighting housing has a grommet which is designed to receive a cable harness.
  • the material of the drum lighting housing preferably has an elastomeric character.
  • the grommet and the drum lighting housing are preferably formed in one piece.
  • the door seal is preferably designed as a door seal ring.
  • the door seal is preferably made from EPDM (ethylene-propylene-diene rubber).
  • the washing machine can be a washing machine or a combination device such as a washer-dryer.
  • the invention relates to a method for producing a door seal with integrated drum lighting with a drum lighting housing, having the following step: Positive connection of the drum lighting housing with at least one door seal connecting section, the positive connection being an overmolding of the drum lighting housing with the at least one door seal -Connection section and / or an injection of the drum lighting housing into the at least one door seal connection section.
