Abstract
A dishwasher includes an outer housing, a drawer having front, rear, bottom and opposing side walls that collectively define a washing tub, a lid for selectively closing the washing tub and an operating mechanism that raises and lowers the lid as the drawer is shifted into and out of the outer housing. The operating mechanism includes a lifting slider slidably mounted in the outer housing operatively coupled to a lifting spring and a compression slider, also slidably mounted in the outer housing coupled to a compression spring. The lifting slider and compression slider are provided with corresponding lifting rollers and compression rollers that engage the lid. As the drawer is withdrawn from the outer housing, the lifting spring urges the lifting slider upward raising the lid and, as the drawer is inserted into the outer housing, the compression slider forces the lid downward onto the washing tub.
