Electrically powered service vehicle

摘要: An electrically powered service vehicle having a plurality of programmable electrical stations is exemplified by food for use with serving trays including internal heating elements providing localized areas heat on the maintaining placed thereon at desired temperature. The has storage compartments, each which holds in vertically spaced relation to other. on-board d-c. power source connected within via contacts compartment. A drive motor propelling selectively through control. compartment are positioned engage corresponding when inserted into compartments. compartments part controllable circuits associated tray station various supplying separately individual heater, and manually operable programming means circuit generate control signals enable or disable separate permit resilient bumper provided front vehicle, switch actuated event an external object, de-energizing also powers air blower forces inlet rear wall directs stream forced forwardly heated side tray. door covering forms outlet adjacent so that flowing exits door.
