Portable wet/dry vacuum cleaner and recharging base
First Claim
1. A portable wet/dry hand held vacuum cleaner comprising a housing having a handle permitting a user to lift and operate said vacuum cleaner and a nozzle/debris container releasably secured to said housing, said housing having a motor and a blower driven by said motor which is in communication with said nozzle/debris container for forcibly drawing air and debris including water into the nozzle/debris container, and said nozzle/debris container being constructed to transmit visible light therethrough along a substantial portion of the nozzle/debris container in order that a user may visually observe the amount of debris collected by the vacuum cleaner within the nozzle/debris container.

Abstract
A portable wet/dry vacuum cleaner is disclosed having a handle base and a combination nozzle/debris container. The handle base comprises a housing having a motor, a blower driven by the motor, and a battery pack for energization of the motor located therein. The blower is in communication with the container for forceably drawing air and entrained debris in the air into the container, for depositing the debris in the container, and for exhausting air from the handle base. A channel is provided within the outer end of the container, which channel extends inwardly and upwardly, but terminates short of the housing. The latter has an air duct between the nozzle/debris container and the blower having an inlet spaced from the inner end of the channel. A deflector is disposed between the inner end of the channel and the inlet of the air duct for directing debris entrained into the air exhausted from the channel away from the air duct inlet. The vacuum cleaner (or appliance) further includes a charging base for holding or mounting the vacuum cleaner. The charging base has a recess formed therein to receive at least a portion of the handle base. The handle base has a receptacle formed therein and a finger from the recharging base fits into the receptacle such that the vacuum cleaner is rotated on the finger toward the recharging base, electrical charging terminal both on the vacuum cleaner and on the recharging base cammingly engage one another thereby to resiliently hold the vacuum cleaner in place on the base and to permit recharging of the batteries within the vacuum cleaner.

5. A method of visually observing the contents of a nozzle/debris container in a portable wet/dry hand held vacuum cleaner in order to separate the nozzle/debris container from the vacuum cleaner for emptying the contents of the nozzle/debris container, comprising the steps of:
-
molding said nozzle/debris container from a transparent plastic resin material in order to transmit visible light therethrough for visibility of the contents of said nozzle/debris container, removably securing said nozzle/debris container to a vacuum cleaner housing having a handle, a motor and a blower driven by said motor to draw air and debris including water into the nozzle/debris container; operating said vacuum cleaner to draw air and debris into the nozzle/debris container; and visually observing the contents of the nozzle/debris container during operation of the vacuum cleaner to determine when it is appropriate to empty the contents of the nozzle/debris container by separating same from the vacuum cleaner housing.

- 6. A portable wet/dry hand held vacuum cleaner comprising a housing having a handle permitting a user to lift and operate said vacuum cleaner and a nozzle/debris container releasably secured to said housing, said housing having a motor, a blower driven by said motor and being in communication with said nozzle/debris container for forcibly drawing air and debris including water into the nozzle/debris container, said nozzle/debris container having an inner end secured to said housing and an outer end, said nozzle/debris container further having a bottom for resting on a supporting surface and a top which extends upwardly and rearwardly from said bottom to said housing, a channel extending from the outer end of and within said nozzle/debris container, the outer end of said channel being proximate the container bottom and constituting an air/debris nozzle inlet, said channel being constructed to extend upwardly and rearwardly from the air/debris inlet toward said housing and terminating in an air/debris outlet short of said housing, a filter positioned between the air/debris outlet of said channel and said housing, and deflector means within said nozzle/debris container positioned between the air/debris outlet of said channel and said filter for deflecting air and debris in a direction away from the filter and into the nozzle/debris container.

13. A portable hand held vacuum cleaner and recharging base, said vacuum cleaner having a housing containing rechargeable battery means and a pair of electrical terminals connected to the rechargeable battery means, said pair of electrical terminals also extending to an outer face of said housing, said recharging base having a frame adapted to receive a portion of said housing therein, said frame having a pair of electrical terminals connectable to a source of electrical energy and being positioned for cooperative electrical connection with the pair of housing terminals to permit recharging of the rechargeable battery means, said housing and frame having spaced cooperating resilient interengaging means for applying a resilient interlocking force across a substantial area of said housing and frame in order to releasably interlock said housing and frame together, said housing and frame terminals being proximately located on said housing and frame relative to at least one of said spaced cooperating resilient interengaging means for engagement of said housing and frame terminals to one another when said housing and frame are releasably interlocked together, said housing and frame also including cooperating finger and notch means for alignment of said housing and frame during the releasable interlocking of said housing and frame to one another, said housing and frame terminals constructed to serve as one of said spaced cooperating resilient interengaging means, and said cooperating finger and notch means constructed to serve as the other of said spaced cooperating resilient interengaging means.
- 14. A portable wet/dry hand held vacuum cleaner comprising a housing having a handle permitting a user to lift and operate said vacuum cleaner and a nozzle/debris container releasably secured to said housing, said housing having a motor and a blower driven by said motor which is in communication with said nozzle/debris container for forcibly drawing air and debris including water into the nozzle/debris container, a debris filter in said vacuum cleaner to filter debris from air drawn into the nozzle/debris container by the motor and blower in said housing, and said nozzle/debris container being constructed to transmit visible light therethrough along a substantial portion of the nozzle/debris container in order that a user may visually observe the amount of debris collected by the vacuum cleaner within the nozzle/debris container.
