ABSTRACT:
A dishwashing machine having a box-like closed main frame with a front vertical opening and a door for closing the front opening. A hinge pivotally interconnects the bottom edge section of the door to the bottom front edge section of the main frame. A latch releasably lockingly anchors the top edge section of the door to the top front edge section of the main frame. The machine is characterized by the way the door joins with the main frame of the dishwasher when the door is closed: the side and top edge sections of the door inner face have two spaced outturned projections forming a continuous U-shape cavity, and the front and side edge sections of the top and side walls of the dishwasher main frame define an inturned U-shape cavity. The U-shape cavities engage each other when the door is closed, to prevent water escape but to allow air circulation through the joint.
