Battery powered dish cleaning device

Abstract

The present invention relates to a cleaning device for use in the kitchen sink having a drive shaft, joint assembly, a housing and a storage rack. The drive shaft rotates about an axis of rotation which is defined by the joint assembly. The drive shaft includes an applicator for cleaning a surface. The applicator may be in the form of a sponge, pad, scourer, brush or other cleaning tool. The surface may be that of a dish, glass, piece of cutlery, cooking utensil, pot, pan or other tableware.

What is claimed is:  
     
         1 . A hand held, waterproof, battery powered dish cleaning device for the purpose of cleaning tableware, dishes, plates, cups, glasses and cutlery, cooking utensils and pots and pans incorporating an adapter fitting and removable base fittings for the attachment of replaceable cleaning sponges, pads or scourers or brush heads to the cleaning device 
 Specifically, in reference to FIG. 5 and FIG. 6, the cleaning head base fitting designs are being claimed.    The present invention provides for rapid changing of the base fittings by the bayonet stud and slot design which incorporates a quarter turn click snap fitting.    The design facilitates rapid and easy change of tool using only a finger and thumb grip on the adapter fitting.    
     
     
         2 . Continuing from  claim 1 , and Referring to FIG. 5, the attachment of the replaceable cleaning sponge, pad or scourer to the cleaning head adapter fitting is claimed 
 The spikes and claws shown in FIG. 5 provide for rapid and easy attachment of a various replaceable cleaning sponges, pads or scourers for the particular task being performed without the need to replace the cleaning head base fitting itself    The design of the claws facilitate engagement with the inner material of the pad scourer or sponge by the action of the pad, scourer or sponge being forced up the ramp angle of the claw in use. The spikes further support the inner fibers of the pad, scourer or sponge and transmit torque to the object being cleaned.    
     
     
         3 . A hand held, waterproof, battery powered dishwashing device that facilitates attachment of replaceable cleaning sponges, pads or scourers or fixed brush heads to the cleaning device that rotate at the optimal rotational speed for efficient cleaning of tableware, dishes, plates, cups, glasses and cutlery, cooking utensils and pots and pans. 
 Optimal rotational speed will enable efficient cleaning, yet not cause excessive splashing or mess around the kitchen sink area, or present an operator hazard. The present invention provides for a device that operates at 300 rpm+/−10% measured at the cleaning sponge, pad, scourer or brush, with sufficient torque to prevent stalling when pushed onto the object being cleaned.
