Abstract
A dishwashing machine constructed to allow quick and easy removal and replacement of the pump/motor used to pump liquid to the spray system. The pump/motor is mounted at a back comer area of the dishwasher cabinet on a track which angles to the center front area of the cabinet. Quick disconnect couplings allow the pump to be disconnected from the piping so that the pump/motor can be slid along the track and removed out the front of the cabinet. Each coupling includes a sealing sleeve located at a pipe joint and a clamp that can be tightened to seal the sleeve against the pipes. The couplings can be loosened by loosening nuts which release the clamps.
Claims20
A machine for washing dishware, comprising:
- a cabinet presenting a wash compartment and a sump for receiving liquid sprayed in the wash compartment;
- a spray mechanism for spraying liquid on dishware in the wash compartment;
- a pump;
- an intake conduit assembly providing a flow path from said sump to said pump, said intake conduit assembly being detachable from the pump;
- a discharge conduit assembly providing a flow path from the pump to said spray mechanism, said discharge conduit assembly being detachable from said pump;
- and
- a track on said cabinet receiving said pump and allowing the pump to move along said track to a position accessible from the exterior of the cabinet when said intake and discharge conduit assemblies are detached from the pump.
A dishwashing machine comprising:
- a cabinet providing a wash compartment and having a front;
- a spray mechanism for spraying liquid in the wash compartment;
- a pump having an intake conduit assembly for receiving liquid and a discharge conduit assembly for supplying liquid to the spray mechanism;
- a pair of pipes in said intake conduit assembly;
- a first detachable coupling sealing said pipes together and being detachable to separate said pipes;
- a pair of conduits in said discharge conduit assembly;
- a second detachable coupling sealing said conduits together and being detachable to separate said conduits;
- and
- a track on said cabinet on which said pump is mounted, said track providing a path along which the pump can slide out the front of the cabinet when said first and second couplings are detached.
In a dishwashing machine having a cabinet, a spray mechanism for spraying dishware, a pump for supplying liquid to the spray mechanism, an intake conduit assembly for supplying liquid to the pump, and a discharge conduit assembly for supplying liquid from the pump to the spray mechanism, the improvement comprising:
- a detachable coupling in said intake conduit assembly allowing the pump to be disconnected from the intake conduit assembly;
- a detachable coupling in said discharge conduit assembly allowing the pump to be disconnected from the discharge conduit assembly;
- and
- a track on the cabinet receiving the pump, said track providing a path along which the pump can slide out of the cabinet when said detachable couplings are detached to disconnect the pump from the intake and discharge conduit assemblies.
