Definitions

  • the invention relates to a domestic appliance with at least one height-adjustable stand.
  • Domestic appliances such as washing machines, tumble dryers or dishwashers, may have height-adjustable feet, which may be e.g. a foot plate with a threaded shaft and a screwed onto the threaded shaft threaded nut include.
  • a movement in the operation of the domestic appliance may change a set height of the base.
  • DE 42 21 079 A1 discloses on the threaded shaft or the thread of the foot nut to apply a coating of plastic.
  • the coating is e.g. executed as an annular circle or semicircle or is applied segment-like or punctiform.
  • the object of the present invention is to provide a domestic appliance with at least one further height-adjustable base, in which a risk of unintentional automatic adjustment of the set height is at least reduced.
  • the solution he task is based on a domestic appliance, in particular water-conducting household appliance, at least comprising a base which is height adjustable by means of a thread.
  • the object of the invention is achieved in that clamping areas are provided which cause an increase in the force required for a threaded operation, so that on a simple way an unintentional adjustment of the feet, for example. By vibrations during operation of the domestic appliance is prevented.
  • the shaft has an external thread.
  • the shaft with the external thread is for example made of plastic, in particular polypropylene.
  • the shank with the external thread can in particular be made in one piece.
  • the base is inserted into a bore in the bottom wall of the household appliance.
  • the bore has a cylindrical inner wall, on which an internal thread is arranged.
  • the radius of the cylindrical inner wall is greater than the outer radius of the external thread of the shaft, so that the shaft with its external thread in the internal thread of the shaft Hole can be screwed.
  • the shaft protrudes differently far out of the hole, ie out of the bottom wall of the household appliance. This allows the height of the stand to be adjusted.
  • a foot plate may be arranged to accommodate e.g. to increase the contact surface of the stand.
  • the foot plate can be made in one piece with the shaft.
  • the inner wall of the bore has at least one thickening.
  • the radius of the inner wall is smaller than the outer radius of the external thread, i. the bore is narrower in the area of the thickening than the shaft provided with the outer thread.
  • the inner wall of the hole has several with respect to a cross-sectional area of the bore arranged thickenings, in whose regions the radius of the inner wall is smaller than the radius of the external thread.
  • a plurality of protrusions are disposed on the inner wall with respect to a transverse sectional area, i. the individual thickenings are arranged substantially annularly on the inner wall. Due to the multiple thickening increases the likelihood that at a desired set height of the base, the external thread is in contact with one of the thickenings.
  • the inner wall is free in areas opposite the individual thickenings Thickened. This allows on the one hand a reliable clamping of the shaft with the inner wall and also allows a screwing of the shaft with the bore.
  • On the inner wall of the bore of the base according to the invention may be arranged an odd number of thickenings, which may be arranged in particular at regular intervals to each other on the inner wall.
  • This embodiment can be made relatively easily and ensures that in areas of the inner wall against thickening the inner wall is free of thickening.
  • the internal thread of the bore can only have a single gear. Due to the thread results in a helix. One full turn of this helix is called a gear. Due to the use of a single passage for the internal thread according to this embodiment, the height of the bore can be made relatively small.
  • the external thread has at least one flattening along the shaft, in the region of which the outside radius of the external thread is smaller than the radius of the inside wall in regions of the thickenings.
  • the external thread can in particular have exactly two opposite flattenings.
  • the multiple thickening embodiment disposed on the inner wall such that the inner wall is free of thickening in areas opposite to a thickening, in combination with the shank whose external thread has the flat, can be relatively easily adjusted, but provides simultaneously a relatively good protection against accidental adjustment of the base by the operation of the household appliance.
  • the number of flattenings may in particular be unequal to the number of thickenings.
  • the at least one thickening, the inner wall and the internal thread may be made in one piece and be made of plastic, for example polypropylene, for example.
  • the bore of the base can be located in particular directly in the bottom wall, wherein the internal thread, the inner wall and the thickenings are integral with the bottom wall.
  • the bottom wall may be made of plastic, e.g. made of polypropylene. This allows a relatively inexpensive production of the bottom wall of the household appliance according to the invention.
  • the household appliance is for example a washing machine, a tumble dryer or a dishwasher.
  • Fig. 3 is a base of the household appliance
  • FIG. 1 shows a dishwasher 1 as an example of a household appliance, which has a bottom wall 2.
  • the bottom wall 2 is made for example of plastic, in particular of polypropylene, for example by means of an injection molding process.
  • the holes 3 each have a cylindrical inner wall 5 with an inner radius r.
  • an internal thread 6 is arranged, which in the case of the present embodiment comprises a single passage 7 and is formed integrally with the inner wall 5.
  • five thickenings 8 formed on the inner wall 5 and formed integrally therewith.
  • FIG. 2 shows three of the thickenings 8.
  • the thickenings 8 are formed annularly on the inner wall 5 at regular intervals and are designed in such a way that regions opposite a thickening 8 are free of thickenings 8.
  • the individual holes 3 with their internal threads 6, their inner walls 5 and their thickenings 8 can, as is the case here, be made in one piece with the bottom wall 2.
  • the feet 4 further each have a shaft 9, shown in more detail in FIG. 4, on which an external thread 10 with several threads is formed.
  • the shaft 9 is integral with its external thread 10, e.g. made of plastic, in particular polypropylene.
  • the external thread 10 is designed such that it corresponds to the internal thread 6 of the holes 3, so that in each of the holes 3, a shaft 9 can be screwed.
  • a hole 3, in whose internal thread 6 a shaft 9 is screwed with its external thread 10, thus constitutes one of the height-adjustable feet 4 of the domestic appliance 1.
  • the end of the shaft 9, not shown in FIG. 4, projects out of the base plate 2 and is intended to be in contact with a surface on which the dishwasher 1 stands.
  • an unillustrated foot plate can be arranged in particular integrally with the shaft 9 on the shaft 9, with which the domestic appliance 1 is on the surface.
  • the outer radius R of the external thread 10 is smaller than the inner radius r of the hole 3
  • the thickenings 8 of the inner wall 5 of a hole 3 protrude so far into the interior of this hole 3 that in their areas the radius of the hole 3 is smaller than the outer radius R of the external thread 10 is.
  • the relevant thickening 8 presses in this area against the external thread 10 and thereby presses the shank 9 against the region of the inner wall 5 of the hole 3 which is opposite the relevant thickening.
  • the shank 9 jams with the inner wall 5, whereby there is a risk of an adjustment of the shaft 9 in the hole 3, for example due to a movement of the dishwasher 1 during its operation is at least reduced.
  • the external thread 10 has two opposing flats 11.
  • the outer diameter R 'of the thread 10 is not only smaller than the radius r of the hole 3, but also smaller than the radius of the hole 3 in areas of its thickenings 8.
  • the flats 1 1 on the shaft 9 are optional.
  • the shaft 9 may also have only one flattening 11 or more than two flattenings 11.
