1354844 Dishwashing machines FISHER & PAYKEL Ltd 25 Feb 1972 [28 Feb 1971] 8827/72 Heading A4F [Also in Division E2] In a cabinet for a dishwashing machine, or other appliance incorporating a vessel, and having a door hinged along a lower edge of a front loading opening, leakage from the vessel below the door is prevented or minimized when the door is closed by the engagement in a channel 12, filled in use of the appliance with water to a predetermined level, of a web 14 depending from alower edge of the door 13. In the illustrated dishwashing machine the channel 12 is filled with water agitated during the washing operation by an impeller. A further web 15 on the door 13 extends over the channel wall 8 and prevents excessive turbulence in the channel 12. A hinging and counterbalancing structure for the door comprises two torsion bar springs 23, one end of each of which extends through a pivot hole 19 in a hinge member 20 secured to the door and is formed with a J-shaped extremity 29 which is held against rotation in a slot 31 in a bracket 32 secured to the machine frame. The opposite end of each spring 23 is held in an aperture 25 and a notch 27 in the hinge member 18. When the door is opened an end 30 of each spring 23 forms a stop engaged by a hooked portion 33 of a hinge member 20, and the resistance to torsion of the springs 23 in part counterbalances the weight of the door. |
