Lipson, 2=3i5 l ryden Road, Eexley, @hio Filed Get. 2, 1961, Ser. No. 142,163 6 Claims. Ii. 15-310) My invention relates to improvements in dust mop cleaning devices.
The principal object of the present invention is to provide a dust mop cleaning device which can be operated when permanently installed in the floor, at a location convenient to the areas generally cleaned with a dry dust mop.
This important feature makes the unit instantly available for use. The user is not required to unwind and connect a cord to an electric outlet or attach the unit to a conventional vacuum cleaner for suction each time it will be used.
Another object of the invention is to locate the operating mechanism below the door level so that no storage space is required. The design will permit the device to be walked upon without loss of floor space.
A further object of the invention is to locate the dust receiving slots ilush with the door, thus making it possible for dust, lint, and sweepings to be pusheddirectly into the suction openings for deposit into the dust collector bag.
Another object of the invention is to provide a suction unit within the appliance, which will be powered by an electric motor, arranged so that the movement of air will draw dust and lint from a dirty mop and deposit this dust and lint in a disposable dust collecting bag made of air pervious material.
A further object of t is invention is to provide the appliance with a hinged cover that can readily be opened exposing the dust collecting bag so that the bag may easily be removed and replaced.
Another object of this invention is to provide a device of simple and practical construction, which will be highly efficient, reliable, and inexpensive to operate and which will be economical to manufacture.
A further object or" this invention is to provide a device for the purposes described that can easily be installed in either new construction or existing homes, apartment buildings, oilice buildings, or other places where its use is desired.
Having described the invention, it is realized that it susceptible to various changes and modifications, and is not, the efore, the desire to limit it to the precise shown and described here.
i aren't from a study of the detailed description which follows, and the accompanying drawings in which:
FIGURE 1 is a plan view of an installation or" a floor mounted dust mop cleaning device embodying my invention;
FEGURE 2 is a sectional side view through lines IIII in FIGURE 1, the upper portion of the dust collector adapter, t e dust collector bag, and the dust collector bag retaining ring being shown however in a section taken along a plane along the longitudinal axis of the dust collector bag;
FIGURE 3 is an enlarged partial or fragmentary view in vertical section taken also along line 11-11 or" FIG. 1
nd illustrating the method of mounting the appliance into the floor;
FEGURE 4 is a side view mainly in elevation and illustrating the relationship between dust mop, floor, and the appliance mounted in the floor;
FEGURE 5 is a fragmentary view on a reduced scale partially in vertical section and partially in elevation showing a portion of the left hand half of the appliance Patented Mar. 3, i964 a li t;
as shown in FIG. 2 in sectio. '0 show the relationship of the inverted cone shaped disk which serves as a protector for impeller) to the impeller and motor;
Fi-GURE 6 is a view also on a reduced scale and in vertical section taken on the line VIVI of FIG. 5 showing th mounting flange which surrounds the open ing in the interior wall between the suction side and the exhaust side of the housing; and
FIGURE 7 is a fragmentary top plan view of the impeller case and impeller case protector, the top of the housing being removed in order to show the impeller case and protector.
As an example of one form in which the invention may be embodied, l have shown in the drawing in FF- URE 2 a housing it divided into two sections by the suction unit mount ll, which is firmly attached to the opposite sides and bottom of the housing 10. Side (:2) is the suction side and side (12) the exhaust side. Suction unit l2 contains an impeller, driven by an electric motor l3, and is located in the suction side of housing 1% which is mounted to the suction unit mount 11 by flange 14. The flange l4 surrounds the opening in the interior wall or suction unit mount ll through which dust laden air is driven by the suction unit 12 into a dust collector bag 17, as subsequently described.
Directly above the air inlet opening in the suction unit 12, an inverted cone shaped disc serving as impeller protector i5 is mounted to protect against solid objects which may fall into the impeller.
On the opposite side of the housing iii, in side (b) the dust collector bag adapter in is mounted to the suction unit mount 11. The opening in the dust collector bag l7 has been slipped over the dust collector adapter 16 is held in place with molded rubber dust collector -.a ning ring The exhaust side of the housing (side 12) is perforated with holes 19 to allow filtered air to escape the unit. In the installation of the unit into the iloor, the housing i is fastened to the sub-flooring with wood screws 2? mounted through the housing mounting clips as as shown in FIGURE 3. The top 29 is retained on the housing by use of top mounting screws 26 into top mounting clips 25, as shown in FIGURE 2. The top Ell is provided with a top cover 21 held in place with top cover hinges 22. A conventional toggle switch (not shown) is located in a wall adjacent to the unit and controls the motor 13 on suction unit 12. A strip of felt or soft compressible material 23 is cemented to the top edges of housing iii to effect an air-tight closure bet: so the top 20 and the suction side (a) of housing id.
When a dust mop (31) is to be cleaned, the switch is engaged and the suction unit 12 draws a large volume of air through the suction slots 2'7. FlGURE 4 illustrates the dust mop 351 as it is moved across the top 29 causing the lint and dirt on the mop 31 to be drawn out of the mop 31 and deposited in the dust collector bag 17. When the dust collector bag 1'7 becomes partially full of dust after occasions of use, with the electric switch in the 01% position, the top cover 21 is placed in the open positron. The dust collector bag 17 will then be accessible. By sliding the dust collector bag retaining ring ll j in a horizontal direction towards the right (as indicated in H6. 2) off of the dust collector bag adapter 16 and off of the dust collector bag 17, the dust collector bag 17 may be removed. A clean bag 17 is then placed into the housing 1% by slipping the mouth of the dust collector bag 17 over the dust collector bag adapter 16. The dust collector bag retainer ring 13 is then moved into the retaining position and it will remain in place as it seats into retaining ring groove 3t? in the neck of the adapter.
