Definitions

  • the present invention relates to a porthole window for a front loading drum washing machine, which has a cup-like shape closed to the inside of the washing machine, with a circular bottom section and a side wall section, the bottom section being formed from a sight glass which has a substantially flat inner surface and has an edge region, and wherein the side wall section of the cup which tapers towards the base section is formed from plastic.
  • a porthole window is attached to the front, which is usually circular and has a sight glass as a porthole window for a front-loading drum washing machine made of transparent material, in order to give the user an insight into the inside of the washing drum.
  • the porthole window With the porthole window open, the laundry can be loaded directly into the drum and taken out again.
  • Corresponding porthole windows for front-loading drum washing machines currently mostly consist of a cup-shaped element made of glass or a transparent plastic material. Since the porthole window forms the opening of the laundry drum, it is important to separate the rotating drum from the Drum and the fixed parts of the machine to create a suitable seal.
  • Such a porthole window is known for example from DE 90 14 622 U1.
  • This document shows a transparent cup-shaped element of substantially hemispherical shape and a comprehensive frame element which is mounted on the outer peripheral edge of the cup-shaped element.
  • the cup-shaped element is preferably made of glass, but can also consist of a transparent plastic material.
  • a disadvantage of the porthole window according to DE 90 14 622 U1 when using transparent plastic is that this does not allow an optimal view into the laundry drum, because it will become cloudy in particular due to chemical attacks and wear and tear from rotating laundry items after a long period of use.
  • the use of glass for a cup-like element is disadvantageous because it makes the porthole window relatively heavy and unwieldy.
  • a porthole window for drum washing machines is known from this document, which is recessed inwards in the area between the outside of the appliance and the washing drum and the recess of which is formed by a collar made of flexible material , which has on the inside facing the drum inward sealing lips for receiving a transparent disc.
  • a disadvantage of this known window is that the sealing lip of the flexible collar facing the laundry drum can become porous with prolonged use due to constant contact with the soapy water.
  • the rotating elastic items can also be used to move the soft elastic sealing lip. With prolonged use, severe wear of the soft elastic sealing lip by the rotating laundry items is also inevitable. These effects permanently impair the desired sealing of the laundry drum. Even the secure hold of the glass pane between between the sealing lips. In addition, when a part of a piece of laundry strikes the soft-elastic sealing lip, this part can be braked suddenly, which can lead to overstressing and possibly tearing of the laundry.
  • the invention has for its object to provide a porthole window of the type mentioned, which is relatively light and handy, ensures a reliable seal of the housing over the period of use of the washing machine and also avoids additional stress on the laundry items.
  • the plastic is a hard elastic material
  • the sight glass is bent in the entire edge region in the direction of the side wall portion such that a rounded glass shoulder is formed, and the sight glass on the outer edge of the glass shoulder an annular, oblique to the inner surface of the sight glass extending connecting portion which is firmly engaged at its head end with the inner end of the side wall portion.
  • the side wall section made of plastic can be kept within narrower tolerances than a glass casting at this point (approx. 1/3 of the glass tolerances). This makes it easier to control the sealing function between the porthole window and the sleeve seal surrounding the window.
  • the head end of the connecting section is advantageously designed such that it has an extension for engagement with a corresponding groove in the inner end of the side wall section, as a result of which a secure connection is ensured.
  • the head end of the connecting section is preferably connected in one piece to the side wall section by injection molding, as a result of which the number of individual components is reduced, which contributes to a reduction in assembly and storage costs.
  • the inner surface of the sight glass is curved toward the cup opening in order to increase the break resistance of the glass.
  • FIG. 1 is a front perspective view of a front loading washing machine with the porthole window open
  • Fig. 2 is a sectional view rotated by 90 ° along the section line A-A in Fig. 1 of a first embodiment of the porthole window according to the invention
  • Fig. 3 shows a detail III of FIG. 3 in section of a second embodiment of the porthole window according to the invention.
  • Fig. 1 shows a washing machine 1 from the front, which is provided with an open porthole window 2 for closing the loading and unloading opening 3.
  • the porthole window 2 shows a preferred embodiment of the porthole window 2 according to the invention.
  • the porthole window 2 consists of a side wall section 4 made of hard plastic material and a bottom section 5, which is formed by a mineral sight glass 10.
  • the sight glass 10 has an inner surface 12 which is slightly arched towards the cup opening.
  • the sight glass 10 is bent in the direction of the side wall section 4 such that a rounded glass shoulder 16 is formed.
  • the sight glass 10 has an annular connecting section 6, which runs obliquely to the inner surface 12 of the base section 5.
  • the connecting section 6 opens into a head end 18, which has an annular extension 22 which extends essentially parallel to the inner surface 12 of the bottom section 5.
  • This extension 22 engages in a head end 20 of the side wall section 4 such that it is in firm engagement with a correspondingly shaped groove 24 at the inner end 11 of the side section 4.
  • the connection is preferably made in that the head end 18 of the preformed sight glass 10 including extension 22 is injection molded around the head end 20 during injection molding of the side wall section 4.
  • the plastic side wall section 4 can also be blown onto the extension 22 of the sight glass 10 in a warm-soft state.
  • the shape of the side wall section 4 can be chosen so that the outer end 30 of the side wall section 4 is formed in one piece as an annular door frame 32.
  • FIG. 3 A second similarly preferred embodiment of the porthole window 2 according to the invention is shown by the detail III shown in section in FIG. 3, which relates to the edge section of the sight glass 10 and the side wall section 4.
  • the head end 18 of the connecting section 6 of the sight glass 10 has an annular extension 26 which initially runs essentially parallel to the inner surface 12 of the bottom section 5 and then approximately perpendicularly thereto.
  • the glass head end 18 is overmolded by the side wall section 4 during injection molding, thereby creating an extremely secure connection.
  • the closed porthole window 2 fills the space of the loading opening between the outside of the appliance and the laundry. out of the drum.
  • the front of the washing drum is thus limited by the sight glass 10 of the porthole window 2, which at the same time ensures that the washing machine user has a clear view of the washing drum.
  • the rotation of the laundry items is harmless for the sight glass 10 because it consists of silicate glass.
  • the contact of the laundry with the silicate glass is harmless to the rotating laundry because the rounded glass shoulder 16 has a soft and smooth structure.
  • the overmolded extension 22, 26 can be T-shaped.
