Damping unit and home appliance with the damping unit
A damping unit for damping a movable element of a home appliance has at least two dampers positioned in a housing. The dampers are positioned side-by-side to guarantee a defined series of damping an energy of the movable element. There is also described a home appliance having the novel damping unit.
1. A damping unit for damping a movable element of a home appliance, the damping unit comprising:
at least two dampers disposed in a housing;
said at least two dampers being positioned side-by-side to guarantee a defined series of damping an energy of the movable element; and
an individual piston for each of said at least two dampers located between the damper and the movable element for contacting the movable element;
a guide on said housing, and a slider on said piston being slidable in the corresponding guide to guide said piston.
2. The damping unit according to claim 1 , wherein a distance between contact points of neighboring said dampers for the movable element is 14-50 mm along a line substantially vertical to a damping direction.
3. The damping unit according to claim 2 , wherein the distance between the contact points is 20-30 mm.
4. The damping unit according to claim 2 , wherein the distance between the contact points is 25-27 mm.
5. The damping unit according to claim 2 , wherein the distance between the contact points is 26.5 mm.
6. The damping unit according to claim 1 , wherein a distance between contact points of neighboring said dampers for the movable element is substantially half of a stroke length of a longer damper of the neighboring said dampers along a damping direction.
7. The damping unit according to claim 1 , wherein said piston has a detachable connection with said housing.
8. The damping unit according to claim 7 , wherein said connection is a form-fit connection.
9. The damping unit according to claim 1 , wherein said slider is limited in the guide to move only along a line substantially parallel to the damping direction.
10. The damping unit according to claim 1 , wherein at least one of said slider or said guide is configured to limit a movement of said slider along a stroke length.
11. The damping unit according to claim 1 , wherein said housing of the damping unit has a locating detail configured to form of a location of the housing to ensure a correction of order of said at least two dampers.
12. The damping unit according to claim 1 , further comprising a sleeve, said housing of the damping unit being detachably fixed inside of said sleeve.
13. The damping unit according to claim 1 , wherein said at least two dampers have different damping characteristics.
14. The damping unit according to claim 1 , wherein said at least two dampers include a first damper having a non-linear damping characteristic starting to damp the movable element first, and a second damper having a linear damping characteristics starting to damp the movable element after start of said first damper.
15. The damping unit according to claim 1 , wherein said at least two dampers include first damper having a linear damping characteristic starting to damp the movable element first, and a second damper having a non-linear damping characteristics starting to damp the movable element after start of the first damper.
16. The damping unit according to claim 1 , wherein said at least two dampers have identical damping characteristics.
17. A home appliance, comprising a damping unit according to claim 1 .
18. A damping unit for damping a movable element of a home appliance, the damping unit comprising:
at least two dampers disposed in a housing;
said at least two dampers being positioned side-by-side to guarantee a defined series of damping an energy of the movable element; and
a sleeve, said housing of the damping unit being detachably fixed inside of said sleeve.
19. A damping unit for damping a movable element of a home appliance, the damping unit comprising:
at least two dampers disposed in a housing;
said at least two dampers being positioned side-by-side to guarantee a defined series of damping an energy of the movable element; and
an individual piston for each of said at least two dampers located between the damper and the movable element for contacting the movable element;
a guide on said piston, and a slider on said housing being slidable in the corresponding guide to guide said piston.
