SUMMARY OF THE INVENTION
In accordance with one embodiment of the present invention, a hand held cleaning apparatus is provided comprising a rigid subassembly shell and a shell cover. The shell has a motor located therein. The shell cover is injection molded around the shell after the motor has been located inside the shell.
In accordance with one method of the present invention, a method of assembling a housing for a motorized appliance is provided comprising steps of connecting members of a shell to each other; and molding a shell cover around the assembled shell to seal areas of connection between the members of the shell.
In accordance with another embodiment of the present invention, a hand held tool is provided comprising a motor, a battery and a housing. The housing has a rigid multipiece subassembly shell and a shell cover molded over the shell. The shell encloses the motor. The cover is comprised of a resilient polymer material that is injection molded onto a majority of an exterior surface of the shell. The cover provides a watertight seal over areas of connection between members that form the shell.
In accordance with another method of the present invention, a method of assembling a housing for a motorized appliance is provided comprising steps of inserting a subassembly shell into a mold, the mold encapsulating the shell therein; moving a slide from within one portion of the mold to cover a deflectable member on the shell; and injecting a polymer material into the mold at a space between the shell and the mold to form a resilient cover over a majority of the shell.
