<p>A table top dishwasher, comprises:
(a) a tub (10) for accommodating articles to be cleaned; and
(b) a water-tight hood (12) located above said tub, said hood comprising two fixed side portions (18), and a curved central region having generally the shape of a cylinder shell the axis of which extends horizontally and the 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 (14; 56) which is joined to said side portions and a door (16; 70) 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 (36; 54) and curved abutment surfaces (46; 68) 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 wherein the center of curvature of the side seals is offset with respect to the center of curvature of the abutment surfaces.</p> |
