Definitions
- the present invention relates to a vacuum cleaner, more particularly, a rotary brush having a plurality of radial channels about on the surface therein, exhausts water onto the surface to be cleaned, said rotary brush being rotated about its own axis by rotational force transmitted from the air fan through the belt pulley.
- the present invention relates to a suction nozzle body with a rotary brush and an air fan for a vacuum cleaner.
- Vacuum cleaners are known in prior art.
- the conventional dry vacuum cleaners have a body with an electrical motor sucking the air with the dirt to be filtered through a tube and put filtered air back into circulation.
- Vacuum cleaners are especially intended to clean dust in carpets and on the floor, usually containing an enormous amount of micro-level dust. The drawn air is then introduced to the filter in the form of a dust-collecting bag.
- Both wet cleaning and dry cleaning vacuum cleaners for the removal of dirt from surface have common practice to provide a motor-driven device which facilitates the collection of the dirt from the floor.
- a vacuum cleaner having wet cleaning function can selectively perform dry cleaning and wet cleaning. When performing wet cleaning, the vacuum cleaner exhausts water onto the surface to be cleaned, and wipes off stains from that surface using the brush, so as to draw in the exhausted water with the stains removed by the brush.
- Document EP0313403 discloses a floor nozzle for use with a vacuum cleaner which has a brush rotatably disposed in housing and which comprises a rotor.
- the floor nozzle also has a turbine rotatable under a vacuum developed by the vacuum cleaner and operatively coupled to the brush for rotating the brush.
- Document US2001011404 discloses a rotating brush, a turbine operationally connected to the brush and the turbine such that the brush and the turbine are rotatably supported.
- vacuum cleaners Before described vacuum cleaners have various disadvantages. They also have the tendency to untwist long filaments from the surface and to draw them out. In the absence of rotating brushes, the bristles are less efficient than the case of rotating brushes mentioned previously in the loosening of dirt.
- the present invention provides that circulated air used in rotating the brush is not directly on the air path through which suction is applied to the surface being cleaned. In contrast, the present invention provides that the air rotating said brush is taken from a separate path through which air suction for cleaning purposes is not effected.
- the present invention comprises rotary brush and wet cleaning function at the same time.
- centrifugal force effects and forces the water to discharge out of the radial channels of the rotary brush.
- Primary object of the present invention is to provide an improved rotary brush having radial channels where water is exhausted onto the surface to wipe off stains from that surface and draws in dust with sprayed water.
- Another object of the present invention is to provide a rotary brush by means of an air fan coupled with a belt pulley which is adapted to be rotated by the drawn air.
- Another aim of the invention is to reduce the cleaning time providing a vacuum cleaner having radial channels on the rotary brush that enables wet cleaning function.
- Another object of the present invention is to provide a rotary brush being arranged to rotate in contact with said surface therefore involving simplicity, reduced noise and necessitating less man-hour work during manufacture.
- Rotary brushes can be performed in various ways.
- First way is electric motor with a rotatable shaft which is connected for example by means of the drive belt to the rotatable brush, so as to transmit a rotational movement to the rotatable brush.
- Second way provides that rotation of the rotary brush is performed by means of an air fan which is mounted generally near the opening of an air intake channel.
- electric motor for performing rotary brush has some disadvantages.
- One of them is that electric power supply from the power line requires a connection between the main body and the electric motor by means of electric cables which constitutes an inconvenience for the user during use of the vacuum cleaner.
- a user When cleaning a place with such a cleaning brush, a user first dips the brush hairs into a detergent and then uses the brush head to brush the dirty place such as a floor or a wall face.
- a cleaning brush According to the present invention an improved cleaning brush has been proposed which can easily be cleaned during operation as the brush itself when operated deep in a cleaning agent cleans off easily.
- the rotary brush is formed with a plurality of radial holes, whereby the water discharges out from the said radial channels.
- Water spraying arrangement on the rotary brush with radial channels of the invention ensures that the suction nozzle can effectively collect dusts; waste threads and any other contaminants from a surface being cleaned, and can therefore maintain a desired high dust-collecting capability.
- the air fan takes in air and expels it in a different direction, comprises frame body with straight blades and rotary fan.
- the frame body with stationary blades creates less wind resistance and outperforms.
- Said frame body with stationary blades performs as a deflector and ensures to reduce noise and increase air pressure for power saving.
- the present invention proposes a vacuum cleaner having an air fan which is equipped with a belt-pulley that rotates a brush and where radial channels are formed longitudinally along said rotary brush whereby the disadvantages of earlier systems are avoided.
- One of the most important functions of the apparatus according to the invention is to increase the dust particle removing performance on the surface to be cleaned.
- a vacuum cleaner has a rotary brush with a plurality of radial channels for use in wet cleaning process.
- a first suction opening is formed in the housing bottom surface.
- a second suction opening is formed at the backside of the main body where the sucked air advances and rotates the air fan.
- the present invention proposes an improved suction nozzle for a vacuum cleaner which is referred to in accordance with the following numerals throughout this description.
- the present invention provides a suction nozzle body for a vacuum cleaner, which includes upper and lower cases (12 and 18) combined in a contacting manner with each other.
- figs. 8 to 11 show the suction nozzle body (10) of a vacuum cleaner.
- the cleaner mainly comprises a rotary brush (11); a belt pulley (17) incorporating an air fan (16) in which rotating process is carried out by sucked air and an air inlet channel (13) formed at the back lower end partition of said suction nozzle body (10).
- the suction chamber (25) has a lower opening where the rotary brush (11) is present.
- Said suction nozzle body (26) essentially comprises an air inlet channel (13) where sucked air is firstly introduced into said suction nozzle body (10).
- an air flow passes firstly through air intake channel (13) and strikes the vanes of the air fan (16), as shown in fig. 5 .
- This causes to rotate vanes of said air fan (16) and a rotational force is created.
- the air fan (16) transmits created rotary movement to the brush (11) through said belt-pulley (17) so as to rotate said brush (11) with its bristles (32) passing over the surface to be cleaned, removing dust and the rubbish which are sucked up by the air flow generated by the vacuum cleaner.
- water or cleaning fluid solution is introduced into said rotary brush (11) by an intake adapter (24)
- Fig 6 shows the path of the water before advancing to the radial channels (23) formed on said rotary brush (11).
- the arrangement of the invention provides that users are provided with an optional wet cleaning function.
- a user may activate wet cleaning by pushing a switch allowing water flow to said water path. In this manner, water is discharged through said plurality of radials channels (23) formed circumferentially along the longitude of said rotary brush (11).
- the radial channels (23), where the water discharges due to the centrifugal force, are provided along the longitude of said rotary brush (11) in a spaced manner serving to the purpose of preventing filamentary dust particle being entangled around said rotary brush (11).
- the present invention substantially contributes to a longer operational efficiency of the brush (11) as its surface is maintained operational in terms of preventing accumulation of filaments.
- a rotatably bent coupling (22) is secured in the rear side of said main body (26).
- the front part of the main body (26) comprises a brush case (20) in which rotary brush (11) is situated.
- Said brush case (20) is provided with an opening facing downward, where said rotary brush (11) comprises a plurality of radial channels (23) receiving water from the intake adapter (24).
- Said rotary brush (11) is mounted thereon by means of a rotation support member (31) formed at the lateral ends of said intake adapter (24) and said rotary transmission part (33)
- the suction hose (14) is introduced into brush case (20) on the backside of the main body (10). Said suction hose (14) directly leads drawn air to the vacuum cleaner.
- said intake adapter (24) which is formed on lateral side of the main body (10) also allows users to remove the rotary brush (11).
- Said rotary brush (11) according to the present invention is designed to be seated on the underlying brush case (20) to be easily removable therefrom.
- Said rotary brush (11) is rotatably supported by rotation support member (31) formed at opposite ends of said brush case (20).
- the suction nozzle body (10) is movable on wheels (15a) located at the backside thereof. Relatively smaller wheels (15b) are formed at the front portion of the suction nozzle body (10).
- Fig. 12b shows a suction nozzle body (10) according to the present invention.
- drawn air firstly enters the suction nozzle body (10) and directly strikes the vanes of said air fan (16), as shown in 13b; that enables simpler manufacture, however, leads to increasing of noise level.
- a solid large-sized dust may be swept by a suction guide wall (29), which is projected below the bottom face of the suction nozzle body (10).
- the rotary brush (11) is rotated by the air fan (16) and thereupon a suction force is generated.
- Said suction guide wall (29) prevents to draw large solid pieces directly to vacuum cleaner.
