Definitions

  • the present invention relates to a dish-rack for a dishwasher, and to a dishwasher featuring such a rack.
  • the present invention relates to a pull-out dish-rack occupying the top part of the wash chamber of a front-loading dishwasher, to which the following description refers purely by way of example.
  • front-loading dishwashers comprise a substantially parallelepiped-shaped outer casing housing a wash chamber which communicates with the outside through an opening formed in one of the vertical lateral walls of the casing; a door hinged to the casing, just below the access opening to the wash chamber, to rotate about a horizontal axis of rotation to and from a substantially vertical closed position, resting against the lateral wall of the casing, to seal the access opening to the wash chamber; and two dish-racks positioned one over the other inside the wash chamber, and resting on supporting rails along which the racks are pulled out.
  • Dishwashers of the above type also comprise two rotary spray washing members, each of which is mounted for rotation inside the wash chamber, just below a respective dish-rack, and has a number of nozzles for directing pressurized-water jets onto the dishes inside the rack above it.
  • Known dish-racks are defined by a rigid, box-like, substantially parallelepiped-shaped basket or container, which is pushed inside the wash chamber along two longitudinal rails fitted to the lateral walls of the casing, inside the wash chamber, and has a bottom wall and four lateral walls made of a number of criss-cross bars forming a grille body that supports the dishes while at the same time allowing the water jets through.
  • the dish-rack occupying the top part of the wash chamber also comprises a substantially rectangular cup-tray hinged, inside the basket, to one of the four vertical lateral walls of the basket to rotate, about a horizontal axis of rotation, between a lowered position - in which the cup-tray is substantially horizontal and at a predetermined height from the bottom of the basket, so as to act as an additional shelf for small glasses and coffee-cups - and a raised position - in which the cup-tray is substantially vertical and rests against the vertical wall of the basket to which it is hinged, to make room for loading large dishes on the bottom of the basket.
  • the overall width of the cup-tray must be more or less equal to the height of the lateral wall of the basket, with the result that, in the raised position, the cup-tray projects beyond the top edge of the lateral wall of the basket by an amount approximately equal to the distance between the axis of rotation of the tray and the bottom of the basket.
  • the part of the tray projecting from the top of the basket obviously limits how close the top dish-rack can be positioned to the ceiling of the wash chamber, so front-loading dishwashers are fitted by the makers with supporting rails that allow the user to manually adjust the height of the top dish-rack according to the position of the cup-tray.
  • Adjustable supporting rails are more expensive than conventional types, with all the drawbacks this entails.
  • adjustable supporting rails are limited to top-of-the-range dishwashers.
  • a dish-rack for a dishwasher as claimed in Claim 1 and preferably, though not necessarily, in any one of the dependent Claims.
  • Number 1 in Figure 1 indicates as a whole a dish-rack, particularly suitable for removable insertion inside the wash chamber of a home dishwasher 2.
  • dishwasher 2 is a front-loading dishwasher comprising a substantially parallelepiped-shaped outer casing 3, in which is formed a wash chamber 3a for housing two dish-racks, preferably, though not necessarily, of different heights and aligned one over the other.
  • wash chamber 3a communicates with the outside through an opening formed in one of the vertical lateral walls of casing 3, and dishwasher 2 comprises a door 4 hinged to casing 3, just below the access opening to wash chamber 3a, to rotate, about a substantially horizontal axis of rotation, to and from a closed position, in which door 4 is substantially vertical and rests against the lateral wall of casing 3 to seal the access opening to wash chamber 3a.
  • dishwasher 2 Inside wash chamber 3a, dishwasher 2 comprises a number of longitudinal supporting rails (not shown) fitted to the inner lateral walls of casing 3 to permit insertion and removal of both the top and bottom dish-rack of dishwasher 2 through the access opening to wash chamber 3a; and two rotary spray washing members (not shown), each of which is mounted for rotation inside wash chamber 3a, just below a respective dish-rack, and has a number of nozzles for directing pressurized-water jets onto the dishes in the dish-rack above it.
  • dish-rack 1 preferably, though not necessarily, occupies the top part of wash chamber 3a, thus constituting the top dish-rack of dishwasher 2, and comprises a rigid, box-like, substantially parallelepiped-shaped container or basket 5 designed to slide into wash chamber 3a along the longitudinal supporting rails fitted to the inner lateral walls of casing 3 defining wash chamber 3a; and a substantially rectangular cup-tray 6, which, inside basket 5, is fixed movably to and projects from one of the four vertical lateral walls - hereinafter indicated 5a - of the basket, so that its two long lateral edges 6a and 6b are locally parallel at all times to lateral wall 5a and to the bottom wall of basket 5.
  • cup-tray 6 is fixed movably to and projects from lateral wall 5a of the basket so it can be set selectively by the user to a lowered position - in which cup-tray 6 is substantially horizontal and at a predetermined height from the bottom of basket 5, so as to act as an additional shelf for small glasses and coffee-cups - or a raised position - in which cup-tray 6 is substantially parallel to, facing, and resting on lateral wall 5a (i.e. in a substantially vertical position), to make room for loading large dishes on the bottom of basket 5.
  • the bottom wall and four lateral walls of rigid, box-like, substantially parallelepiped-shaped container or basket 5 are made of a number of criss-cross bars forming a grille body that supports the dishes while at the same time allowing the water jets through; and cup-tray 6 is defined by a flat, substantially rectangular grille, the length w of the long lateral edges 6a and 6b of which is approximately equal to, but no greater than, the length of lateral wall 5a of the basket measured parallel to the edge between lateral wall 5a and the bottom wall of the basket.
  • cup-tray 6 of dish-rack 1 is connected to lateral wall 5a of basket 5 by an oscillating-arm connecting member 7 comprising at least one bottom oscillating arm 8 and at least one top oscillating arm 9, which are hinged, one above the other, to lateral wall 5a of basket 5 to rotate freely about two axes of rotation parallel to and spaced apart from each other, and each of which is substantially coplanar with lateral wall 5a and locally parallel to the edge of basket 5 between the bottom wall and lateral wall 5a of the basket.
  • an oscillating-arm connecting member 7 comprising at least one bottom oscillating arm 8 and at least one top oscillating arm 9, which are hinged, one above the other, to lateral wall 5a of basket 5 to rotate freely about two axes of rotation parallel to and spaced apart from each other, and each of which is substantially coplanar with lateral wall 5a and locally parallel to the edge of basket 5 between the bottom wall and lateral wall 5a of the basket.
  • bottom oscillating arm 8 lies in a plane locally perpendicularly to lateral wall 5a, and has a first end hinged to lateral wall 5a to rotate freely, with respect to lateral wall 5a, about a first axis of rotation A locally coplanar with lateral wall 5a and locally parallel to the edge of basket 5 between the bottom wall and lateral wall 5a of the basket; and a second end hinged to the body of cup-tray 6 - roughly along the long lateral edge 6a positioned adjacent to lateral wall 5a when cup-tray 6 is in the lowered position - so as to rotate freely, with respect to cup-tray 6, about a second axis of rotation B locally parallel to axis of rotation A.
  • Top oscillating arm 9 also lies in a plane locally perpendicular to lateral wall 5a, but on the opposite side of bottom oscillating arm 8 to the bottom of basket 5, and has a first end hinged to lateral wall 5a to rotate freely, with respect to lateral wall 5a, about a third axis of rotation C locally parallel to and spaced apart from axis of rotation A; and a second end hinged to the body of cup-tray 6, in the space between the two long lateral edges 6a and 6b of the cup-tray, to rotate freely, with respect to cup-tray 6, about a fourth axis of rotation D locally parallel to axis of rotation C.
  • bottom oscillating arm 8 and top oscillating arm 9 are designed so that the distance between axes of rotation C and D is greater than that between axes of rotation A and B; and top oscillating arm 9 is hinged to lateral wall 5a, above bottom oscillating arm 8, so that the distance between axes of rotation A and C substantially equals the distance between axes of rotation C and D.
  • oscillating-arm connecting member 7 of dish-rack 1 comprises two bottom oscillating arms 8 and two top oscillating arms 9, in both cases parallel to and facing each other.
  • Top oscillating arms 9 move in the space between the short lateral edges of cup-tray 6 and the two lateral walls of the basket adjacent to lateral wall 5a, i.e. move in two planes (parallel to the Figure 2 plane) locally perpendicular to lateral wall 5a and to the bottom of basket 5, and locally substantially tangent to the two lateral walls of the basket adjacent to lateral wall 5a; while the two bottom oscillating arms 8 move, parallel to and facing each other, in another two planes inside the space bounded by the planes of the two top oscillating arms 9.
  • the design of oscillating-arm connecting member 7 enables the user to selectively rotate cup-tray 6 simultaneously about axes of rotation A and C into a lowered position ( Figure 2 ), in which cup-tray 6 is substantially horizontal, at a predetermined height from the bottom of basket 5, with long lateral edge 6a substantially resting against lateral wall 5a of the basket, between axes of rotation A and C; and into a raised or fold-up position ( Figure 3 ), in which cup-tray 6 is parallel to and facing lateral wall 5a, with both long lateral edges 6a and 6b resting against lateral wall 5a, and with long lateral edge 6a at a minimum distance from the bottom of basket 5.
  • axis of rotation D is at a minimum distance from axis of rotation A, and axis of rotation B at a maximum distance from axis of rotation C; and, in the lowered position ( Figure 2 ), axis of rotation B is at a minimum distance from axis of rotation C.
  • oscillating-arm connecting member 7 in the raised or fold-up position, the cup-tray no longer projects from the perimeter of the basket, so the top dish-rack of the dishwasher need no longer be lowered when the cup-tray is in the raised or fold-up position.
  • dishwasher 2 may be a chest type, as described in U.S. Patent US-7152612 .
