Description
Patented Mar. 7, 1950 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to novel apparatus for cleaning furniture upholstery, carpets, rugs, and the like, and for similar cleaning operations.
The invention has for an object to provide a novel cleaning apparatus for carrying on cleaning operations by either a shampooing method or a dry vacuum method or both; the apparatus being so constructed as to be readil and quickly selectively conditioned for operation by either said method.
The invention has for another object to provide a compact, simple and easily operated mobile cleaning apparatus for the above stated purposes which can be economically produced, and which, to these ends, includes a main container, a second container, adapted to hold a detergent solution, mounted within said main container, an electrically operated blower fan mounted on the main container with its intake or suction side in communication with the interior of said main container, means being provided for disconnectibly coupling the discharge of said blower fan in communication with the bottom interior of said second container, whereby to pass forced air through said second container and its contained liquid detergent for suds producing effect and for delivery of the produced suds from said second container to a manipulatable suds applying means; and said main container having an inlet means to which a manipulatable suction means may be coupled.
The invention has for a further object to provide a novel form and disposition of air deflector means within the second container for eiiiciently directing admitted air for substantially uniformly distributed suds forming flow through the detergent solution contained in said second container.
Other objects of the invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.
An illustrative embodiment of the invention is shown in the accompanying drawings, in which:
Fig. l is a central vertical cross sectional view through the cleaning apparatus made according to the invention; Fig. 2 is a top plan view of said cleaning apparatus; Fig. 3 is a fragmentary vertical cross sectional view, similar to that of Fig. l, but showing the means for delivering forced air to the second container disconnected from the discharge of the blower fan, and showing a dust collecting bag connected with the latter; and Fig. 4 is another fragmentary vertical cross sectional view showing a suction means operatively coupled to the inlet means of the main container.
Similar characters of reference are employed in the above described views, to indicate corresponding parts.
Referring to the drawings, the reference character l0 indicates the complete cleaning apparatus embodying the principles of this invention, the same comprising a main container H having a bottom wall I 2 which is supported by and suitably afiixed to a carriage member Hi. The carriage member I3 is equipped with casters l4, so that the cleaning apparatus as a whole is rendered mobile, and thus subject to be conveniently moved about from place to place. The open top end of the main container II is normally closed by a cover member [5 which is removably afliXed to the main container by fastening bolt and nut means l6, or by any other suitable form of fastening means. Although said main container Il may be made of any suitable shape, it is preferably of the cylindrical shape shown. The bottom wall 42 of the main container H is provided with a clean-out opening I! which is normally closed by a removable closure plug I3.
Supported within the interior of the main container ll, intermediate the top and bottom of the latter, is a second container I9 which is closed top and bottom by a top wall 20 and a bottom wall 2|. Said second container I9 is of smaller diameter than that of the main container II, and is mounted within the latter, so as to be preferably disposed in concentric relation thereto. The second container it may be supported within the main container by any suitable means, such e. g. as by the radial brackets 22 which extend from the side walls of said main container II. The second container I9 is provided in connection with its top wall 20 with a filling neck 23, the outer open end of which is normally closed by a removable closure plug 24.
Suitably mounted on and affixed to the cover member l5 of the main container H is a blower fan 25 and its actuating electric motor 26. The casing or housing 21 of the blower fan is provided with an axial air intake 28 which communicates with the interior of the main container I! through an opening 29 in said cover member US with which it is aligned. The blower fan casing or housing 2'! is further provided with an outlet or discharge member 30 which extends outwardly therefrom.
The main container ii is provided, preferably in a suitable location for exterior projection from a side thereof, with an air inlet nozzle or spout 3|.
Connected with the bottom wall 2| of the second or interior container |9, so as to discharge into the bottom interior of the latter, is the discharge end portion 32 of an air delivery conduit 33. Said air delivery conduit 33 extends to and through the side wall of said main container H, and terminates in an external upstanding intake portion 34. The inlet end 35 of said intak portion 34 is disposed in a plane above the level of a liquid detergent solution 36 with which the second or interior container I9 is supplied when the cleaning apparatus is in use. To said inlet end 35 of the air delivery conduit is connected, preferably by a swiveling connection 31 of suitable design, a flexible air hose 38. The free end of said flexible air hose 38 is provided with a suitable coupler member 39 adapted for detachable engagement with the outlet or discharge member 30 of the blower fan casing or housing 21, whereby, when required, to connect the air delivery conduit with the blower fan so as to deliver the air output of the latter through the air delivery conduit to and through the second or interior container H) for purposes hereinafter more particularly set forth.
Leading outwardly from the top of said second or interior container i9 is a discharge conduit G0, which extends to and through the side wall of the main container I I, and which terminates in a discharge nozzle or spout 4| which projects exteriorly from said main container Suspended within the second or interior container 59, by suitable supporting means such e. g. as the hanger 42, and so as to overhang the discharge end 32 of the air delivery conduit 33, in suitably spaced relation to and above the latter, is an air deflector or spreader bafile 43. Preferably, the form of said air deflector or spreader bafiie is that of a hollow cone, the open bottom of which opposes the discharge end 32 of the air delivery conduit 33.
Prior to putting the cleaning apparatus in use, a liquid detergent solution 36 is supplied to the second or interior container IS in quantity suflicient to submerge the air deflector or spreader baflie 43, and yet to but partially fill said container, so as to leave open space within the interior of the latter above the level of the supplied solution.
In the useof the cleaning apparatus, when it is desired to operate the same to carry on a cleaning operation by a shampooing method, the flexible air hose 38 is connected to the discharge member 30 of the blower fan, whereupon electric current is supplied to motor 26 so as to operate said blower fan. The air inlet nozzle or spout 3| being open to the atmosphere, the operating blower fan sucks air from the atmosphere into the main container II and thence through the opening 29 and blower fan intake 28. The thus operating blower fan discharges air from its discharge member 3!} through the air hose 38 and air delivery conduit 33 for discharge into and through the liquid detergent solution within the second or interior container IS. The stream of air thus entering the container i9 will be deflected by the air deflector or spreader baiiie 43 so as to be directed outwardly from the rim of the latter to pass into the solution in such manner as to be substantially uniformly distributed laterally in all directions, and thereupon so as to bubble upwardly therethrough. The ebullition of air through the solution so agitates and aerates portions of the same as to produce lather, foam or suds which is accumulated within the upper interior of the container |9 above the level of the solution therein. The continued flow of forced air thus discharged by the blower fan through the container |9 will discharge the produced lather, foam or suds through the discharge conduit 40 and discharge nozzle or spout 4|. Thence the lather, foam or suds may be delivered to the furniture upholstery, rug, carpet or other material, desired to be cleaned by a shampoo treatment, by attaching to the discharge nozzle or spout 4| a flexible hose 44 which terminates in a suitable applicator member 45, through which the lather, foam or suds may be discharged for application to the material to be cleaned.
After application of the lather, foam or suds to the material to be cleaned has been satisfactorily accomplished, the applied lather, foam or suds, together with the dirt taken up thereby, can be removed from the material under treatment by adjusted operation of the cleaning apparatus. To condition the apparatus for lather, foam or suds removal, the hose 44 and its applicator member 45 is detached from the discharge nozzle or spout 4|, and attached to the inlet nozzle or spout 3|, or a similar hose having a suitable suction head is attached to said inlet nozzle or spout 3| (see Fig. 4). The flexible air hose 38 is thereupon disconnected from the discharge member 30 of the blower fan (see Fig. 3), thus preventing delivery of air from the blower fan through the second or interior container I9 and its detergent solution content. When the apparatus is thus conditioned, and the blower fan again put in operation, air will be sucked through the applied hose and its suction head into the interior of the main container The air suction thus induced will take up the soiled lather, foam or suds from the material being cleaned, and will carry the same into the interior of the main container where it will fall out of the air stream so as to accumulate in the bottom of said container I. The main container may be emptied of accumulated soiled lather, foam or suds through the bottom opening ll of the main container II when the closure plug I8 is removed. The interior of the main container may be thoroughly cleansed by removing the cover member l5 for access thereto. The supply of detergent solution in the second or interior container [9 may be renewed while the cover member I5 is removed so as to give access to the filling neck 23.
When it is desired to operate the cleaning apparatus by a dry vacuum method, the apparatus is conditioned in the same manner as above described for soiled lather, foam or suds collection, except that a dust collection bag 46 (see Fig. 3) is coupled to the discharge member 30 of the blower fan.
From the above, it will be apparent that the instant invention provides a very simple, compact and light weight cleaning apparatus adapted to be optionally conditioned for either shampoo cleaning effect or for dry vacuum cleaning efiect. The apparatus is further simplified in that but a single blower fan is required, the air circulation which is induced thereby being quickly and easily conditioned and controlled by the mere coupling and uncoupling of the flexible air hose 38 relative to the discharge member 38 of the blower fan.
It will be obvious that various changes could be made in the constructions and arrangements of the above described cleaning apparatus and its parts without departing from the scope of this invention as defined by the here-following claims.
aeeaeve 5 a It is therefore intended that all matter contained in the above description or shown in the aceompanying drawings shall be interpreted as illustrative and not in a limiting sense.
