Abstract
A sealing device is provided between a bullseye-shaped porthole of a loading door and a housing wall in washing machines or laundry dryers and includes a one-piece, substantially annular sealing collar. The porthole has an edge section, which extends substantially parallel to the plane of the loading door. The sealing device includes, at its end facing the porthole, a head section that is supported by a projection on an edge section of the housing wall limiting the door aperture. Furthermore, the sealing device includes a narrow, substantially annular sealing disk that, with the loading door closed, presses sealingly in the axial direction against the edge section of the porthole.
Claims27
A household appliance, comprising:
- a housing having a wall defining a door aperture, said door aperture having an edge section with a projection;
- a loading door defining a door plane;
- a bullseye-shaped porthole disposed in said door, said porthole having:
- an edge section extending one of substantially in said door plane and substantially parallel to said door plane;
- and
- a porthole axis;
- and
- a sealing device providing a seal between said porthole and said wall, said sealing device having a one-piece, substantially annular sealing collar with:
- an end facing said porthole;
- a head section at said end supported by said projection;
- and
- at least one substantially annular sealing disk sealingly pressing in an axial direction with respect to said porthole axis against said edge section of said porthole when said loading door is closed.
In a household appliance having:
- a housing wall defining a door aperture with an edge section having a projection;
- a loading door defining a door plane;
- and
- a bullseye-shaped porthole disposed in the door, the porthole having a porthole axis and an edge section extending one of substantially in the door plane and substantially parallel to the door plane,
- a sealing device for providing a seal between the porthole and the wall, the sealing device comprising:
- a one-piece, substantially annular sealing collar having:
- an end facing the porthole;
- a head section at said end to be supported by the projection;
- at least one substantially annular sealing disk sealingly pressing in an axial direction with respect to the porthole axis against the edge section of the porthole when the loading door is closed.
A sealing device for a household appliance, the sealing device comprising:
- a one-piece, substantially annular sealing collar having:
- an end to be disposed facing a bullseye-shaped porthole in a loading door of the appliance, the loading door defining a door plane, the porthole having a porthole
- axis and an edge section extending one of substantially in the door plane and substantially parallel to the door plane;
- a head section at said end to be supported by a projection on an edge section of a door aperture defined by the housing wall;
- at least one substantially annular sealing disk adapted to sealingly press in an axial direction with respect to the porthole axis against the edge section of the porthole when the loading door is closed and establish a seal between the porthole and the housing wall.
