摘要： A filter assembly for a vacuum cleaner of the type having a motor, a housing enclosing the motor, a fan driven by the motor for producing a vacuum, and a canister removably attached to the front end of the housing and having an intake nozzle for reception of foreign matter, liquid and air drawn into the canister in response to the vacuum developed by the fan. The filter assembly includes an air permeable filter member disposed within a framework. The filter member includes a front wall. A hollow member extends axially from the front wall towards the open end of the canister. The hollow member is readily graspable by a user when the canister is removed. The filter assembly further includes a filter housing disposed within the canister and having a front wall. A member axially extends from the front wall towards the open end of the canister and is accessible by the user when the filter is removed from the filter housing.

摘要： An electric toaster includes a housing defining a toaster cavity. A comestible support rack is mounted within the toasting cavity for supporting the bread to be toasted in a horizontal plane within the cavity. The toaster includes first and second heaters mounted respectively above and below the support rack. The cavity includes radiant energy reflecting surfaces above and below the support tray to direct energy generated by the heaters of the toaster to uniformly toast each side of the comestible. Heat shields are positioned between each of the heaters and the food support rack. The heat shields aid the reflective surfaces in uniformly toasting the surfaces of the comestible.

摘要： A dust bowl of a hand-held vacuum cleaner is attached to a power unit using top and bottom latches which are actuated by pushing a single actuator button. Both latches are outside a sealed space through which air flows, and are thus not sources of air, soil of liquid leakage. A wishbone-shaped pusher transmits mechanical actuation forces from the actuator button for actuating the upper latch to a spring bar connected to a bottom latch cam. When the actuator button is pushed, the spring bar is correspondingly moved to release the bottom latch in coordination with release of the top latch. A forward support member of the power unit cradles a portion of the dust bowl to provide support and lateral stability between the elements. A tab extends from the bottom of the dust bowl to overlap a forward edge of the forward support member to provide further stability to the fit.

摘要： A hand-held vacuum cleaner including a housing comprising mating first and second half housing elements. The housing has a handle and a nozzle. A motor is mounted within the housing for driving a shaft. A fan is mounted on the shaft for rotation therewith. A selectively separable bag assembly is mounted on the housing. A working channel is defined within the housing communicating the nozzle with the bag assembly. A connector joins a hose or similar attachment to the vacuum cleaner. The connector extends the flow path of the working air from the attachment to the nozzle. The connector comprises a first section for direct engagement with the attachment and a second section adapted for fitting over the housing in underlying registration with the nozzle. The second section includes a fluid flow channel and an edge wall surrounding the fluid flow channel and an edge wall surrounding the fluid flow channel and having an extent and configuration to fit in substantially fluid tight engagement with the nozzle. A pair of spaced apart hook-shaped projections extend outwardly from the edge wall. A releasable latch is movably connected to the edge wall on the side opposite the projections.
