Definitions

  • the invention relates to an aggregate for a washing machine and a washing machine.
  • rubber bumpers are used to compensate for tolerances between components and to dampen vibrations.
  • the invention has as its object to provide an improved unit for a washing machine and an improved washing machine.
  • the unit in the at least one receiving device has a structure which is adapted to compensate for tolerances by deformation and to dampen vibrations by elasticity.
  • the structure has ribs that are thin enough to be squeezed when connecting the motor to the unit. The same ribs act as short bending springs, which absorb vibration energy through elastic deformation.
  • the achievable with the present invention consist in addition to the compensation of component tolerances and the damping of vibrations in a reduced assembly costs and reduced manufacturing costs by reducing the number of components and operations used.
  • An aggregate for a washing machine wherein the aggregate has a tub made of a plastic material and a motor interface for a drive motor of the washing machine, wherein the motor interface is integrally connected to the tub and at least one holder with a through-hole having a rib structure for a Aufwmedom of the drive motor.
  • a central functional element of a washing machine In the unit fastening elements and functional elements are united.
  • a washing drum of the washing machine In the tub, a washing drum of the washing machine is rotatable stored.
  • the drive motor can be coupled with the washing drum, for example via a belt drive.
  • the motor interface can be molded onto the tub.
  • a receiving dome may be a fastener of the drive motor.
  • the receiving dome may have aligned in several axes stop surfaces.
  • the holder may have corresponding stop surfaces.
  • the through hole may form a stop surface in two axes.
  • the rib structure may have at least three ribs distributed diametrically over a circumference of the through-hole. With three ribs, the receiving dome can be supported in two axes. An even number of ribs may also be formed in the through-hole. Then two ribs can always be arranged in pairs opposite one another.
  • Ribs of the rib structure may be aligned axially with the through hole. Due to the axial alignment, a simple tool for production can be used.
  • a back of the ribs can be designed tapering.
  • a tapered rib acts like a progressive spring, which provides a strong increasing force to an increasing deformation.
  • the back of the ribs can be designed as a surface.
  • the surfaces may be aligned substantially parallel to a wall of the through-hole.
  • the ribs may thereby have a trapezoidal or rectangular cross section.
  • the surface results in a large contact surface between the receiving dome and the ribs.
  • the surface can also be made concave.
  • the surfaces of the ribs may be partial surfaces of a core bore of the through-hole.
  • the rib structure may have a greater clearance at a first end of the through-hole between two diametrically opposed ribs than at a second end of the through-hole opposite the first end.
  • the through-hole may have a larger diameter at a first end of the through-hole than at a second end of the through-hole opposite the first end. Thereby, a height of the ribs over the entire length of the through hole can be defined.
  • the motor interface may have at least one further holder with a further through hole.
  • the further through hole may have another rib structure.
  • the rib structures may differ. Thereby, various spring forces of the ribs in the various through holes can be achieved.
  • a washing machine is presented with an aggregate according to the approach presented here and a drive motor, wherein in the at least one through hole of the secured by a lag screw receiving the drive motor is arranged, wherein the receiving mandrel squeezed at least in a portion of the through hole part of the rib structure.
  • FIG. 1 shows a representation of a washing machine 100 with an aggregate 102 according to an embodiment.
  • the unit 102 includes a tub 104 and a motor interface 106.
  • a washing drum 108 of the washing machine 100 is rotatably mounted.
  • a drive motor 110 of the washing machine 100 is attached.
  • the drive motor 110 is coupled to the wash drum 108 via a belt drive.
  • the motor interface 106 here has two holders 112, each with a through hole 114.
  • the holders 112 are molded onto the tub 104.
  • a rib structure 116 is formed in each of the through holes 114.
  • the rib structure 116 has been produced by injection molding.
  • the pick-up domes 118 are pulled into the through-holes by lag screws. In this case, the receiving domes 118 abut against ribs of the rib structure 116.
  • the rib structures 116 are deformed when retracted from the receiving domes 118 to compensate for tolerances.
  • FIGS. 2 and 3 show representations of an aggregate 102 with mounted drive motor 110 according to an embodiment.
  • the unit 102 and the drive motor 110 essentially correspond to the illustrations in FIG FIG. 1 , Here, a single holder 112 is shown.
  • the through hole 114 has a larger diameter than the receiving mandrel 118. A resulting gap is filled by the rib structure 116.
  • the rib structure 116 has eight ribs 200 here.
  • the ribs 200 are aligned in the axial direction in the through hole 114.
  • the ribs 200 are integrally connected to the holder 112.
  • the ribs 200 are designed tapering.
  • At the top of the ribs 200 is a contact surface with the receiving mandrel 118. The small contact surface results in a large surface pressure. A resultant force in the single rib 200 may thereby be great enough to deform the rib 200. Thus, component tolerances between the drive motor 110 and the motor interface can be compensated.
  • a hard motor connection is shown on the NMT tub 102.
  • the drive motor is mounted on the tub. This can be done via additional components, such as rubber bushings, which dampen the vibrations. So far, either a vibration rubber or a very rigid, non-elastic rigid connection is used.
  • the swing bushings have the task of achieving a decoupling between the tub 102 and the motor 110. By decoupling the vibrations can be damped and noise can be reduced.
  • the swing bushings also allow a certain tolerance compensation.
  • An alternative connection is presented, which does not require swinging bushings.
  • the conical rib geometry 116 allows safe assembly and tolerances can be compensated.
  • the assembly is very simple, yet a secure fit of the motor 110 is ensured.
  • the special geometry 116 presented here combines the cost advantages of a hard motor connection and the soft motor connection, ie the vibration damping and the axial tolerance compensation with each other.
  • the through hole 114 is provided with ribs 200 which allow axial and radial tolerance compensation.
  • a vibration damping and thereby also an acoustic reduction are achieved by the softer than the solid material ribs 200.
  • the system is inexpensive because no additional components are needed.
  • the axial and radial tolerance compensation is achieved by squeezing the ribs 200. Due to the softer ribs 200 energy is absorbed during operation, for example when spinning and not transferred to the entire tub 102 or the entire unit 102.
  • FIGS. 4 and 5 show sectional views through a holder 112 with mounted drive motor 110 according to an embodiment.
  • the holder corresponds essentially to the in the FIGS. 1 to 3 shown holders.
  • the receiving mandrel 118 is conical here. Thereby, the receiving mandrel 118 can be inserted with a thin end into the through hole 114 and between the ribs 200, respectively. Upon insertion, at the point where the diameter of the receiving mandrel 118 corresponds to the clearance between the ribs 200, direct contact between the drive motor 110 and the holder 112 occurs for the first time.
  • the receiving mandrel 118 is hollow with an internal thread for a tension screw 500 executed.
  • the lag screw 500 braces on a back side of the holder 112 using a washer.
  • the ribs 200 are squeezed and the contact pressure between the receiving mandrel 118 and the ribs 200 increases.
  • the receiving mandrel 118 can be pulled into the through hole 114 until a receiving surface 502 of the receiving mandrel abuts a stop surface 504 of the holder 112.
  • the receiving mandrel 118 is laterally offset from a center of the through hole 114. In this case, the receiving mandrel 118 rests against the ribs 200 only on one side. On the opposite side, the receiving mandrel 118 does not abut the ribs 200.
  • FIG. 6 shows a representation of an aggregate 102 according to an embodiment.
  • the unit 102 substantially corresponds to the unit in the FIGS. 1 to 3 ,
  • the unit 102 here has a first holder 112, a second holder 600 and a third holder 602 on.
  • the first holder 112 has the first through hole 114 with the first rib structure 116.
  • the second holder 600 has a second through-hole 604 with a second rib structure 606.
  • the third holder 602 has a third through-hole 608 with the second rib structure 606.
  • the first rib structure 116 corresponds to that in FIG FIG. 2 illustrated rib structure.
  • the second rib structure 606 has eight flattened ribs 200. The surfaces on the ribs 200 are substantially parallel to a wall of the through-holes 604, 608.
  • FIGS. 7 to 9 show spatial representations of an aggregate 102 according to an embodiment.
  • the unit 102 substantially corresponds to the unit in FIG. 6 .
  • the rib structures 116, 606 are tapered.
  • a clear width between two opposite ribs on the side of the stop surfaces 504 is greater than on the opposite rear side of the holders 112, 600, 602.
