A table top dishwasher generally includes a tub and a water-tight hood located above the tub, the hood including a central region that includes a fixed portion which is joined to two side portions and a door which is rotatably connected to the side portions, the hood includes a sealing arrangement comprising curved side seals and curved abutment surfaces extending along the lateral edges of the door, wherein when the door is closed a contact pressure is exerted between the side seal and the abutment surfaces in a direction perpendicular to the axis of rotation of the door, wherein the radius of curvature of the side seals substantially corresponds to the radius of curvature of the abutment surfaces, and the center of curvature of the side seals is offset with respect to the center of curvature of the abutment surfaces. |

1. A table top dishwasher, comprising:
(a) a tub for accommodating articles to be cleaned; and (b) a water-tight hood located above said tub, said hood comprising two fixed side portions, and a curved central region having generally the shape of a cylinder shell the axis of which extends horizontally and a lower section of which has been cut away so as to merge into the upper edge of the tub; said central region comprising a fixed portion which is joined to said side portions and a door which is rotatably connected to the side portions, the door being rotatable between a closed position in which it forms part of the cylinder shell, and an opened position in which the door at least in part superposes the fixed portion, said hood further comprising a sealing arrangement for said door, the sealing arrangement comprising curved side seals and curved abutment surfaces extending continuously along the lateral edges of the door, wherein when the door is closed a contact pressure is exerted between the side seal and the abutment surfaces in a direction perpendicular to the axis of rotation of the door, wherein the radius of curvature of the side seals substantially corresponds to the radius of curvature of the abutment surfaces, and wherein the center of curvature of the side seals is offset with respect to the center of curvature of the abutment surfaces to facilitate the contact pressure when the door is closed, wherein when the door is opened the contact pressure is substantially reduced or terminated. |
