<p>- 13 A washing appliance includes a wash receptacle and a lid assembly for closing an open top of the wash receptacle. At least a peripheral portion of the lid assembly is movable toward and away from the open top of the wash receptacle between a sealed condition contacting the periphery of the open top and an unsealed condition spaced away from the periphery of the open top. The closing forces applied to the lid, the shape and stiffness of the lid assembly, and the shape of the top periphery of the receptacle are such that when the peripheral portion of the lid is pressed against the receptacle into the sealing condition, the variation in sealing pressure across the width of the forward sealing portion of the lid is less than would be expected for a lid assembly of the same stiffness where the shape of the lid assembly and receptacle provide a uniform clearance across the width of the forward sealing region with the lid raised.</p> |
