Definitions

  • washing machine is described in WO 03/066 952 A1.
  • this washing machine is one of several means for preventing the entrainment of thrown-off water caused by the spinning of the rapidly rotating laundry drum air flow from the space between the coats of the laundry drum and the tub through the annular gap between the sleeve and the loading opening of the laundry drum in the Drum drum is coupled back, formed by the fact that a barrier lip is arranged on the sleeve in the way of the air flow as a flow resistance.
  • this lip can not be effective protection against the forming air flow; because the locking lip is rigidly mounted and the laundry drum moves relative to the locking lip. This creates a circumferential, wide gap between the barrier lip and the outer surface of the laundry drum so that the barrier lip is not an effective barrier to airflow.
  • this object is achieved by the characterizing features of claim 1 in such a way that the locking lip rests with its free ridge line on an annular region of the laundry drum and the annular region of the laundry drum forms a Kugelkalottenabrough whose radius from a point of Drum axis goes out, which is at least close to the storage of the laundry drum.
  • the locking lip is not parallel to the radius on the surface of the Kugelkalottenabitess.
  • the blocking lip can follow the height stroke of the rotating abutment surface softly in the case of the smallest irregularities of the spherical cap section, since the elasticity is utilized transversely to the longitudinal extent of the cross section of the blocking lip.
  • the annular area is at least 10 mm wide form.
  • the exact device of this width is u. a. depend on the materials used as well as on the dimensions of the laundry drum and their storage and on their volume-related capacity to dry laundry.
  • the locking lip advantageously extends from one of the annular connection with the container opening inwardly to the height of the edge of the feed opening reaching, with respect to the elastic regions of the sleeve dimensionally stable collar, and the longitudinal extent of its cross section is parallel to the drum axis.
  • the collar is formed in an advantageous manner lip-like on its inner edge, and the lip-like shape is flush with the inner edge of the feed opening.
  • FIG. 1 is a schematic, perspective front view of part of a washing machine according to the invention
  • Fig. 2 shows a cross section through a part of the front portion of the machine housing, the cuff, the tub and the laundry drum with the inventive design of a locking lip and
  • Fig. 3 is an enlarged detail view according to the designated in Fig. 2
  • a washing machine housing 1 which has a loading and unloading opening 2 for the supply and removal of the laundry in the laundry drum 3 on the front.
  • the laundry drum 3 - not visible in detail here; However, indicated by dashed lines - is enclosed by the tub 4 and rotatably mounted therein about a horizontal axis.
  • its drum axis 5 coincides with the bearing axis 6, which is a fixed component of the tub 4.
  • the orientation of this bearing axis 6 may also differ from the horizontal. In general, this is a forward tilt of less than 15 ° selected. Accordingly, then the tub 4 with its container opening 7 and the drum axis 5 are inclined.
  • the camp for the laundry drum 3 is located behind its rear wall 31 in the rear bottom of the tub 4 and consists of two bearings, not shown. Their storage levels are represented by the line crosses 61 and 62. Their crossing points 63 and 64 lie on the bearing axis 6.
  • a cuff 8 For fluid-tight connection of the loading and unloading 2 in the machine housing 1 and the container opening 7 in the tub 4 is a cuff 8, which allows a certain mobility of the tub 4 relative to the machine housing 1.
  • a detergent dispensing device 9 is arranged, which can be supplied with fresh water via supply lines from the rear side-not shown here.
  • the fresh water supply can be controlled by solenoid valves not shown by a program device at selected times or depending on the level. Then, not shown detergent chambers are rinsed and their contents transported together with fresh water on the floor drain 10, the Waschstoffein Kunststofftechnisch 1 1 and the inlet 12 into the tub 4.
  • spring struts 13 For oscillating support of the system of tub 4 and its not shown here further units such as drive motor, ballast weights, heating, inlet and outlet fittings serve spring struts 13. These contain springs and friction dampers. They are based on the one hand on the bottom 14 of the housing 1, and on the other hand, they support the tub 4.
  • the front part shown in Fig. 2 in the region of the filling openings is guided in a section along the drum axis 5 intersecting vertical plane.
  • the connection between the housing 1 and the sleeve 8 encloses the loading and unloading opening 2 of the machine housing 1.
  • the sleeve 8 is a short tubular rubber part, which is folded once on the way to the container opening 7 of the tub 4 (fold 15).
  • the sleeve 8 is similar to the front side of the machine housing 1 by means of a ring spring 16 in a flute 17 attached to the tub 4. Both fasteners are liquid-tight, so that when the door is closed in the loading and unloading 2 (not shown) no liquid can reach the outside or outside of the tub 4.
  • a collar 19 which projects from the edge of the container opening 7 from transverse to the drum axis 5 inwards and approximately at the level of the edge 20 of the feed opening 21 of the laundry drum 3 ends (Fig. 3).
  • the collar 19 is made of the same elastic material as the rest of the sleeve 8, but has a much more voluminous profile so that it can stably withstand the hard adjacent parts of the laundry drum (edge 20, surfaces on the laundry drum, see below).
  • the collar 19 At its inner edge, the collar 19 has a lip-like formation 22, with which it extends very close to the edge 20 of the feed opening 21 zoom.
  • the distance A1 is less than 4 mm, so that no laundry parts between the edge 20 and the lip-like shape 22 can get advised.
  • the lip-like molding 22 is very elastic due to its blade-like shape, small deflections of the rim 20 of the charging opening 21 can not cause damage even when touched.
  • the forehead bottom 23 of the laundry drum 3 is arched out towards the edge 20 of the charging opening 21, similar to a truncated cone (FIG. 2), and contains an annular region 24, the outer surface of which forms the portion of a spherical cap.
  • the radius R of this spherical cap (see also Fig. 1) is very long and extends into the region of the bearing 61 to 64 of the laundry drum 3.
  • the center 25 of the spherical cap between the bearing points 63 and 64 because it is assumed can that the deflection of the drum axis 5 during the unbalanced deflection of the laundry drum 3 during the spin just between these two bearing points 63 and 64 is formed.
  • the deflection will also make up only a small angle ⁇ (FIG. 3), which already gives a width B of about 10 mm over this radius length. So wide should therefore be the annular area 24 on the front floor of the laundry drum 3 at least.

  • the ridge line 27 should preferably have a distance A2 ⁇ 0 mm, so that always a seal against the above dreaded air flow can be guaranteed. Since the locking lip 26 designed sufficiently thin and thus is very elastic, it can follow an additional slight height stroke of the laundry drum 3. Therefore, the blocking lip 26 is also not perpendicular to the annular region 24. provides.
  • the rotating pendulum motion of the laundry drum 3 observed during spinning causes no pressure change on the barrier lip 26 at the line of contact between the ridge line 27 and the annular area 24 because the periphery of the annular area 24 lies exactly in the pendulum line 28 of its surface. In any case, this causes no pressure fluctuation or bending stress in the blocking lip 26.
  • the lip-like formation 22 still cooperates with the blocking lip 26 in "emergencies.”
  • current setting of the distance A1 and the position of the gap resulting therefrom should still be a piece of laundry get the gap, then "saves" still the lip 24, which is in reality only about 20 mm from the gap, the laundry before the complete creeping. It is then expected to be released again from the gap with further drum rotation and transported back to the laundry.
