Vacuum cleaner with dust disposal
First Claim
1. A detachable dust collector for use with a vacuum cleaner having a main body including an inlet opening and an outlet opening with an electric fan being operatively positioned therebetween, said dust collector comprising:
- a housing having a top, bottom and two side walls adapted to be removably disposed within said main body and operatively positioned between said inlet opening and said electric fan;
primary filter means for trapping dust and objects of a predetermined size being operatively positioned within said housing;
said primary filter means including a horizontal wall extending from one side wall to the other side wall and a vertical wall being spaced from said bottom wall of said housing and extending from said top wall to said horizontal wall to define a dust collection chamber adapted to be in communication with said inlet opening and a first path being positioned between said horizontal wall of said primary filter means, said two side walls and said bottom wall of said housing;
secondary filter means for trapping dust and objects of a predetermined size being operatively positioned within said housing downstream of said primary filter means, said secondary filter means being spaced from said vertical wall to define a second path being in communication with said first path;
said secondary filter means extending between said top, bottom and both side walls of said housing to form an air permeable end closure for said housing; and
a movable lid being operatively positioned on an open front of said housing and being hinged about said top wall for forming a closure thereto, said lid including an opening adapted to be in communication with said inlet opening and said dust collection chamber and said lid being in engagement with said horizontal wall of said primary filter means and said bottom wall for closing the front of said dust collection chamber and said first path;
wherein detaching said dust collector from said vacuum cleaner and moving said lid to an open position permits dust and objects to be discharged in a single tilting action from said dust collection chamber of said primary filter means and from said first and second paths being in communication with said secondary filter means.

Abstract
According to the present invention, there is provided a vacuum cleaner which comprises a dust collector detachably installed in a main body of the cleaner. A primary filter composed of a horizontal wall and a vertical wall is disposed within the dust collector. Both the horizontal and vertical walls are permeable to air and include a dust filter. A secondary filter is disposed behind the vertical wall of the primary filter. A first path for dust is defined btween the horizontal wall of the primary filter and the bottom of the body and merged into a second path developed between the vertical wall of the primary filter and the second filter. Preferably, the horizontal and vertical walls of the primary filter include a coarse mesh for trapping relatively large dust and the secondary filter includes a fine mesh for trapping relatively small dust which has passed through the primary filter. A lid is provided on the side of the primary filter opposite the vertical wall for discharging dust accumulated on said primary and secondary filters.
