  • Another object of the present invention is to provide a dust disposal device which may advantageously use the dust collection bags commercially available in the market.
  • the dust collection bag is folded, but its opening is connected to the opening end of the dust collection box so that when the dust and dirt collected in the dust collection box are disposed, the dust collection box is removed from the main body of the vacuum cleaner and the dust collection bag is extended so that the dust and dirt in the dust collection box may be transferred into the dust collection bag.
  • the dust collection bag containing the dust and dirt may be disposed of in a garbage can or the like.
  • FIG. I is a side view, partly in section of an electric vacuum cleaner in accordance with the present invention.
  • FIG. 2 is a longitudinal sectional view, on enlarged scale of a dust collection box thereof;
  • FIG. 3 is a perspective view thereof with the dust collection box being removed from the main body
  • FIG. 4 is a perspective view illustrating the method for transferring the dust and dirt collected in the dust collection box into a dust collection bag
  • FIG. 5 is a sectional view illustrating the method of removing the dust bag from the dust collection box
  • FIG. 6 is a view illustrating the method of handling the dust collection bag removed from the dust collection box
  • FIG. 7 is a perspective view illustrating the attachment of the dust collection bag to a dust collection bag holder.
  • FIG. 8 is a longitudinal sectional view illustrating a variation of the dust collection bag holder shown in FIGS. 3-7.
  • a vacuum cleaner in accordance with the present invention generally comprises a wheeled main body 1 with wheels 38 and a handle 3 and having an electric-motor-driven fan 2 housed therein; and a front dust collection box receiving section 6 formed integral with the main body 1 and separated therefrom by a partition wall 4 made integral therewith and provided with an opening 5; and a dust collection box 7 removably received in the front section 6 of the main body 1 as best shown in FIG. 3.
  • the reference la of FIG. 3 includes an exhaust opening.
  • the dust collection box 7 has a handle 10 formed integral therewith at the top of the box 7, an opening 8 and a suction port or suction pipe connection 9.
  • the dust collection box 7 is generally divided into two chambers, a first dust collection chamber 13 and a second dust collection chamber 18, by a pre-filter 11 and a main filter 15 each having an end removably fitted into a guide groove 12 formed in the inner wall surface of the dust collection box 7.
  • the pre-filter l1 and the main filter 15 are fitted into the guide groove 12 with a packing 16 interposed therebetween so as to provide dusttightness.
  • the pre-filter 11 comprises a screen so that the dust and dirt which are relatively large in particle size are trapped by the pre-filter 11 and collected in the first dust chamber 13.
  • the dust and dirt which is very fine in particle size which pass through the pre-filter 11 are trapped by the main filter 15 having a mesh smaller than that of the pre-filter 11 and collected in the second dust collection chamber 18 between the pre-filter 11 and the main filter 15.
  • a dust exhaust port 17 is provided on the side of the opening 8 of the dust collection box.
  • a push button 19 extends from the handle 10 and is normally biased to move upwardly under the force of a spring 20 loaded between the flange 19a of the push button 19 and a portion of the handle 10 as best shown in FIG. 2, but is prevented from moving out of the handle 10 by the flange 19a.
  • a lever 21 which is pivotably fixed to the dust collection box 7 with a pivot pin 22 has its one end 23 engaged with the lower end 19b of the push button 19 and has its the other end engaged with the upper edge 27 of a cover 26 which is pivotably fixed to the dust collection box 7 with a shaft 2.5 to cover the opening 8 of the dust collection box 7 as best shown in FIGS. 4 and 5.
  • a dust collection bag holder generally denoted by 29 is fitted into the stepped portions formed along the bottom and side edges of the opening 8 and interposed between the opening 8 and the cover 26.
  • the dust collection bag holder 29 holds the opening edge of adjustablet collection bag 30 made of a substantially impervious material such as paper or plastic sheet such as polyethylene.
  • the dust collection bag holder 29 comprises an inner frame 32 and an outer frame 31 which is pivotably fixedto the inner frame 32 with pivot pins 34 of the outer inner frame 32 fitted into bearing members 33 formed on the inner frame 32.
  • the opening'edge of the dust collection bag 30 is held between the inner and outer frames 32 and 31 as the latter is fitted over the former.
  • the outer frame 31. is made slightly greater than the inner frame 32.
  • a handle 35 is rotatably fixed to the inner frame 32 of the dust collection bag holder 29 so that the latter may be removed from the dust collection box 7 with ease and without causing the hands to become soiled as shown in FIGS. 4-7.
  • the handle 35 of the dust collection bag holder 29 has a dust collection bag retaining member 36 formed integral with the handle 35 and is normally located at the center of the dust collection bag holder 39.
  • the dust collection bag 30 is folded as shown in FIG. 2 and its bottom portion 30a is securely retained between the cover 26 and the retaining member 36 so that the dust collection box 30 may be prevented from being sucked into the dust collection chambers during the operation.
  • a dust collection bag holder 29a is formed integral with the dust collection box 7 along the opening 8a thereof.
  • the opening edge of the dust collection bag 30 is fitted over the dust collection bag holder 29a and is securely retained in position with a rubber band or the like 39.
  • the vacuum cleaner of the present invention has many advantages which may besummaried as follows:
  • the dust collection bag may be securely held between the pair of frames of the dust collection bag holder with the opening edge of the bag interposed therebetween so that the dust collection bag may be easily and rapidly attached to the holder.
  • the dust collection bag may be easily attached to. the bag holder. Furthermore, when the pair of frame members are fitted together with the dust collection bag held therebetween and are locked in position by suitable locking means, the dust collection bag may be more firmly attached to the bag holder.
  • a sanitary and easy dust disposal may be made because the operator may use the handle to remove the dust collection bag holder from the dust collection box and dispose 'of the dust collection bag into a garbage can or the like.
  • the dust collection bag receiving member is formed integral with the rotatable handle of the dust collection bag holder, the bottom portion of the dust collection bag may be securely held between the dust collection bag receiving member and the cover as best shown in FIG. 2 so that the dust collection bag may be prevented from being sucked into the dust collection chamber to adversely affect thereby the operation of the vacuum cleaner.
  • a dust collection box for collection of dust removably connected to said main body and having an inlet, a dust collection chamber, and an opening defining a dust outlet communicating with said dust chamber;
  • said dust collection box and main body defining an air duct extending from said inlet to said outlet by way'of said motor driven fan;
  • a filter positioned across the flow path in said air duct and being removably fixed to said dust collection box;
  • a substantially impermeable dust collection bag having an open end detachably held by said ring like bag holding body to the said opening for removal of collected dust in said dust collection box, said bag being folded when said dust collection box is connected to said main body.
  • An electric vacuum cleaner as set forth in claim 1 comprising a handle on said bag holding body for facilitating the removal of said holder from said box.
