Dish washing machine with a vertically movable door blade
First Claim
1. A dishwashing machine comprising a vertically movable door which when closed seals against frame sides of a door opening leading to a treatment chamber in which dishes are washed by spraying the dishes with washing liquid, said door opening including a bottom, substantially vertical part (28) which is located on a front side of the chamber (10), and a top part (30) which extends obliquely upwards and inwards into the machine;
- said door comprising at least one bottom and one top section (22,
26) which are pivotally connected together;
said door being carried by a pair of pivot arms (38) which are pivotally mounted for rotation about a horizontal pivot axis (36) which lies substantially midway between front and rear walls (12,
14) of said chamber, said pivot arms having outer ends which are connected to the door via hinge joints (50 and 40 respectively) between the bottom and the top section;
said bottom section being guided by a pair of link arms (42) which are pivotal about a horizontal axis (44) located beneath the pivot axis (36) of the pivot arms (38), said link arms having outer ends which are pivotally connected to the bottom section; and
said top section being arranged such that upper and lower end edges of said top section follow an arcuate path which substantially coincides with an arcuate path of the hinge joints between the top and the bottom section from a closed, inwardly inclined position of the top section to an inner terminal position near the rear wall of the chamber.

Abstract
A dishwashing machine having a vertically movable door which when closed seals against the frame sides of a door opening leading to a treatment chamber (10) in which dishes are washed by spraying the dishes with washing liquid. The door opening includes a bottom, substantially vertical part (28) located on the front side of the chamber, and a top part (30) which extends obliquely upwards and in towards the machine interior. The door comprises a bottom and a top section (22, 20) and a center section (24), which are pivotally connected to one another. The sections are supported and guided by pivot arms (38) and link arms (42) in a manner such that when pulling up the door from its closed position, the top section will swing into the machine to a position adjacent the rear wall (14) of the chamber.
