Abstract
Description
- The invention relates to electric household appliances and in particular to an accessory device to be applied to vacuum cleaners and electric brooms in order to augment their performance.
- In the use of vacuum cleaners or electric brooms, the need is felt to augment the performance of these devices with other functions, particularly the cleaning of carpets and fitted carpets, polishing of any kind of floor and mattress beating.
- Electric cleaning accessories for carpets and fitted carpets, provided with an electric power supply coupling and with an air intake to be fitted on a vacuum cleaner or on an electric broom, are already known; accessories for electric floor-polishers, with two or three rotating circular brushes and with an air intake to be fitted on vacuum cleaners or electric brooms and also provided with a power supply coupling, are known too.
- Mattress beating accessories with an air intake are also known.
- All these conventional accessories are devices conceived and manufactured in order to perform a single function; accordingly, the carpet cleaner can act only as a carpet cleaner, the polisher can only work as a polisher, etcetera.
- The aim of the present invention is to provide an accessory, to be fitted appropriately and when necessary on vacuum cleaners, electric brooms etcetera, provided with a power supply coupling, usable for cleaning or polishing floors, for cleaning carpets or fitted carpets, for beating mattresses etcetera, and which can be configured for a plurality of functions.
- Within the scope of this aim, an object of the present invention is to provide an accessory which has a compact and lightweight structure, which allows quick and easy using in connection with a vacuum cleaner or an electric broom and also allows safe operation, all without drawbacks linked to excess heating of the motor.
- This aim, this object and others which will become apparent hereinafter are achieved by an improved electric household appliance fittable according to requirements, on vacuum cleaners, electric brooms or the like and/or to be used as a stand-alone electric household appliance, which comprises a base with wheels, supporting an electric motor which is kinematically connected to a roller-like implement, the base being provided with means for fixing to a vacuum cleaner, an electric broom or the like or to a handle and with a seat for the roller implement, characterized in that said seat is provided with means for detachably accommodating said roller.
- Advantageously, said accessory is provided with an air intake to be connected to the suction duct of a vacuum cleaner.
- Further characteristics and advantages of the present invention will become apparent from the following detailed description of an embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Figure 1 is a top view of the accessory according to the present invention;
- Figure 2 is a sectional view, taken along the plane II-II of Figure 1;
- Figure 3 is a top view of the accessory without the covering dome;
- Figure 4 is an enlarged-scale detail view of the region of the means for engaging the roller with the base;
- Figure 5 is a longitudinal sectional view, taken along a vertical plane of the accessory.
-
- With reference to the above figures, an accessory according to the invention has, under a covering dome 1, a
base 2 which supports anelectric motor 3 which in this case is arranged horizontally and to the rear of aroller 4 which constitutes the cleaning implement. - In the
motor 3, theshaft 5 has alateral output 6 on which a driving pulley 7 is fitted; said pulley is coupled, by means of adriving belt 8, to a drivenpulley 9 which has a larger diameter, so as to provide a reduction in the rotation rate, and is rotationally rigidly coupled to a pivot 9a which is supported by aflange 10 which is accommodated within aseat 10a formed on thebase 2. - A seat 10b is formed opposite to an end of the
roller 4, in thebase 2, and retains aflange 10c which supports apivot 19a on which acoupling 19 is rigidly coupled so that it can slide with respect to said pivot but rotates rigidly with it; saidcoupling 19 is pushed toward the end of theroller 4 by a spring 19b which is arranged between said coupling and theflange 10c. - The pivot 9a and the
coupling 19 have a head which has a toothed frustum-shaped profile which is adapted to fit in a complementarily shaped seat, designated by the reference numerals 9b and 19d respectively, of theroller 4. - The translatory stroke of the
coupling 19 is at least equal to the extent by which the head of the pivot 9a or of thecoupling 19 can enter the respective seat. - This is done in order to allow interchangeability of the
roller 4. - In the central part of the
base 2 there are twosmaller wheels 11a, whereas in the rear part twolarger wheels 11b are provided which are meant to facilitate the movement of the fitted accessory during operation. - By means of a preset position of the rear wheels and of the possibility, as explained in detail hereinafter, to vertically adjust the
roller 4, the bristles of said fittedroller 4 can yield if the load becomes excessive. - The
base 2 furthermore has, behind theroller 4, aslot 12 which acts as air intake (said air being drawn by the vacuum cleaner if the accessory is fitted thereon) communicating further through the interior of the accessory, by way of aduct 13, with thefitting articulation 14 suitable for fitting on the hose of the vacuum cleaner. - The accessory according to the invention is furthermore provided with a
switch 15 allowing a switching on of the device after thepower supply cable 16 has been connected to the power supply coupling of the vacuum cleaner or of the electric broom, not shown. - On the dome 1, a
knob 17 is instead provided (or an equivalent device) whose lower part 17a is shaped like an inclined plane on which ahorizontal axle 21 rests; said axle supports, at its ends, correspondingvertical sliders 21a which can slide in theseats 10a and 10b and rigidly support theflanges - By turning the
knob 17 so as to lower theaxle 21, in contrast withelastic means 22, which tend to push thesliders 21a upward, the vertical elevation of theroller 4 is changed, as shown by the dashed lines of Figure 5. - The possibility to modify the height of the operating position of the
brushing roller 4 that is fitted as a carpet cleaner allows to render the load of the motor constant regardless of the height (length) of the pile of the carpets being treated. - A luminous indicator, not shown and, preferably but not necessarily, red, can be provided in order to warn, for example, depending on the current absorbed by the motor, when the load of said
motor 3 is too high, indicating the need to actuate theknob 17 in order to change the distance of theroller 4 being used with respect to the surface being treated. - Other luminous and/or acoustic indicators can be provided in order to report the status of the machine (on, off, etcetera) to the operator.
- By fitting a
handle 18 to thearticulation 14 and by providing it with a suitable power supply cable, not shown, and equipped with a two-pin plug to be connected to a mains outlet, said accessory can be used as a stand-alone, floor-polisher, electric household appliance, without a vacuum effect. - As an alternative, the accessory without the
roller 4 can also operate as a vacuum cleaner even with no roller fitted, being actuated directly by the electric household appliance to which it is joined and therefore without requiring any switching on. - In practice it has been observed that the intended aim and object of the present invention have been achieved.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
- All the details may also be replaced with other technically equivalent elements.
- The materials and the dimensions may be any according to requirements.
- The disclosures in Italian Patent Application No. MI98A002672 from which this application claims priority are incorporated herein by reference.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
