Abstract
A hardbox upright vacuum cleaner having a filter bag cleaning brush within the box which is operable by a handle projecting from the box. The filter bag is enclosed within the box and is filled with a stiffening material, such as short fibers. Dirtladen air is drawn against the outside surface of the bag so that the dirt is collected on the bag surface. The collected dirt is scraped from the bag surface by the bag cleaning brush. A removable dirt collecting box is provided beneath the bag for disposal of the dirt.

SHEEI 2 BF 2 FILTER BAG CLEANING MEANS BACKGROUND OF THE INVENTION There have been various proposals for cleaning the dirt and lint from the filtering material in vacuum cleaners. In those vacuum cleaners which do not include disposable dirt bags, it has been proposed to remove the dirt and lint from the filtering material by employing devices which either vibrate or beat the material. Examples of filter vibrators are shown in U.S. Pat.
Nos. 2,488,300; 2,522,498; 2,522,709; 2,534,578; 2,558,429; 2,585,508; and 3,484,889. Examples of filter heaters are shown in U.S. Pat. Nos. 2,564,734 and 2,586,876. These beater and vibrator devices are employed with filter constructions which may be easily vibrated or beaten.
There are filter constructions, however, which are not easily cleaned by the foregoing devices. For example, there is disclosed in U.S. Pat. No. 3,160,908 a sweeping machine having a dust separator which includes a plurality of depending filtering pockets through which the air is forced for separating the dust on the outer surfaces of the pockets. The pockets may contain a separator to maintain the sides of the pockets in spaced relation. The outside surface of the filter pockets is cleaned during use, since the pockets move in a pendulum fashion as the machine changes direction and speed. In addition, a mechanism is provided to bounce the pockets up and down to loosen accumu- Iated dirt.
Although the arrangement shown in U.S. Pat. No 3,160,908 may effectively clean the filter pockets, such an arrangement is unsuitable for cleaning filter pockets provided in a hand-operated hardbox upright vacuum cleaner, since the pockets in such a cleaner are not vertically suspended for pendulum motion during normal cleaning operations and since it is impractical to make the box large enough to accommodate such motion in a hand-operated cleaner.
SUMMARY OF THE INVENTION This invention provides a cleaning mechanism for pocket-type filters in a hardbox upright vacuum cleaner which effectively cleans the filter without relying upon motion of the pockets or upon mechanical agitation or beating of the filter material. According to this invention, a hardbox upright vacuum cleaner is provided with a filter which includes a plurality of Iongitudinally extending filter pockets within the hardbox portion of the cleaner having their upper ends joined to a manifold. Each pocket is spaced from each other pocket and is filled with a stiffening material, such as coarse fibers or the like. A cleaning brush assembly having a plurality of spaced brushes is mounted within the box so that the brushes engage the exposed planar surfaces of the filter pockets. The brush assembly is provided with a handle which projects from the box so that by grasping the projecting end of the handle, the brushes may be caused to traverse the planar faces of the filter pockets. A removable dirt box or collector is provided below the filter pockets to catch the dirt which is brushed from the filter pockets. The brushes maintain the filter pockets in a separated condition when the box is in any position during cleaning operatrons.

DETAILED DESCRIPTION OF THE DRAWINGS In FIG. 1 of the drawings, there is illustrated a hardbox upright vacuum cleaner 10. The hardbox upright vacuum cleaner 10 includes a motor and fan housing 1 1, a brush nozzle portion 12 which may be removably attached to the housing 11, in a manner more fully set forth in copending application Ser. No. 299,345, filed Oct. 20, 1972, a filter housing 13 which is pivotally connected to the motor housing 11, and an operating handle 14.
As is customary in hardbox upright-type vacuum cleaners, a first hose 15 extends from the brush nozzle portion 12 to the filter housing 13. A second hose 16 extends from the housing 13 to a motor fan unit (not shown) within the housing 11. Thus, air is drawn by the motor fan unit from the portion 12 through the first hose 15, the housing 13, the second hose l6, and then through a suitable clean air exhaust (not shown).
As may be seen most clearly in FIG. 4, a filter unit 17 is mounted within the housing 13. The filter unit 17 includes a plurality of pockets 18 which open into a header or manifold 19. The pockets 1 8 may be sealed to the manifold 19 by a suitable adhesive and/or rivets (not shown). The pockets 18 are filled with a stiffening material 20 which may comprise a multiplicity of rubberized hair or bristles.
The manifold 19 is fixed to the upper end of the housing 13 and has a downwardly extending elbow extension 21 which is attached to one end of the hose 16. The other hose l5 communicates with an elbow extension 22 which is provided at the lower end of the housing 13.
First and second axially extending ducts 23 and 24, respectively, are sealed to the sides of the housing 13, as may be seen most clearly in FIG. 3. The duct 23 carries the hose 15 at its lower endto prevent kinking of the hose during operation of the cleaner. The duct 24 carries the hose 16. The housing 13 and the upper ends of the ducts 23 and 24 are sealingly capped by a cover 25 upon which the handle 14 is mounted. The lower ends of the ducts 23 and 24 are removably fixed to hinge members (not shown) which are provided on the housing 11.
The bottom end of the housing 13 is closed by a dirt box 26. The dirt box 26 may be removed for cleaning by releasing a latch 27 and by sliding the box 26 rearwardly with respect to the housing 13 along guide runners 28 formed in the lower end of the housing 13 (FIG. 4).
As may be seen most clearly in FIG. 4, the motor fan unit draws air through the hose 16. This air is filtered,
since it is drawn through the filter pockets 18. Thus, dirt-laden air is drawn from the brush nozzle 12 through the hose 15 and the dirt is deposited on the external surface of the filter pockets 18. Of course, some dirt will fall into the dirt box 26. Eventually, however,
- the outside surface of the filter pockets 18 will become coated with dirt and lint,
To remove the dirt from the outside surface of the filter pockets 18, there is provided a filter cleaning brush assembly 29. The brush assembly 29 includes a rod 30 having a handle 31 at its upper end and a mounting plate 32 at its lower end. The plate 32 is fixed to the rod by a pair of nuts 33. A plurality of brushes 34 project from the plate 32 and are spaced apart so that their bristles bear against the planer surfaces of the pockets 18, as may be seen in FIG. 3. The plate 32 has a narrowed neck portion 35, which projects through a longitudinal slot 36 in the housing 13. The rod 30 extends within the duct 23 and projects through the cap 25. In order to maintain suction through the casing 13, a suitable seal (not shown) is provided between the rod 30 and the cap 25. A seal 37 is provided in the duct 23 beneath the rod 30.
When the surfaces of the pockets l8 become covered with dirt and lint (thereby reducing the efficiency of idly separated condition so that they are spaced from each other and from the sidewalls-of the housing 13.
The invention is not restricted to the slavish imitation of each and every detail set forth above. Obviously, devices may be provided which change, eliminate, or add certain specific details without departing from the scope of the invention. What is claimed is:
1. A vacuum cleaner having a motor housing, a suc-v tion nozzle connected to said housing, an elongated filter box for filtering dirt-laden air picked up by said nozzle, first conduit means connecting said nozzle to one end of the interior of said filter box for conducting said dirt-laden air to a first portion of said interior, second conduit means connecting said motor housing to the other end of the interior of said filter box for conducting fiitered air from a second portion of said interior to a fan means Within said motor housing, filter means within said box and separating said first and second portions, said filter means comprising a plurality of elongated filter bags fixed at said other end of said filter box and having freely hanging distal ends extending toward said one end, said filter bags having stiffened planar faces and being arranged in spaced face-to-face apposition, brush means engaging each planar face of said filter bags adjacent said distal ends and providing the sole spacing means for those ends, and means to move said brush means along said planar faces toward.
