Definitions

• the present invention relates to a vacuum cleaner that provides the grounding of the built-up static electric charge formed due to friction during suction of dust /dirt.
• electrostatic charges of extremely high voltages tend to build up, due to the friction created by the impact of the dust/dirt laden to the inner surface of the metallic extension tube.
• electrostatic charges mostly occur on the extension tube may create a potential danger both for the user and the equipment.
• USA Patent No. 3711742 relates to draining off the static electricity built-up in the extension tube, by grounding it through the user.
• a conductor disposed between the metallic tube and the handle with which the user is in continuous contact causes the electrostatic charge to be grounded and does not allow it to be accumulated in the extension tube.
• this method is not very healthy from the user point of view.
• a vacuum cleaner comprising a rotatable brush, a handle and an extension tube, which are mechanically or pneumatically interconnected, wherein the electrostatic charge is dissipated or drained off from its components to the surrounding air, by means of an annular corona discharge element having a roughened surface and serrations.
• the object of the present invention is to realize a vacuum cleaner that can provide the grounding of the electrostatic charges built-up due to friction, from the base of the dust collector nozzle.
• Figure 1 is the schematic view of the vacuum cleaner.
• Figure 2a is the schematic view of the ring, wire and shield.
• Figure 2b is the schematic view of the ring with a projection and the wire.
• Figure 3 is the exploded, three-dimensional view of the brush, extension tube, elbow, ring and wire.
• Figure 4 is the bottom view of the brush.
• the vacuum cleaners (1) include a body (10) containing the motor unit that realizes the suction function and the control unit; a flexible hose (11); an adapter (12) connected to the hose to facilitate the handling of the hose by the user; a metallic extension tube (2) connected to be adapter (12); and a brush (4) fitted on the end of the extension tube (2) to clean the rugs and/or floors.
• the vacuum cleaner (1) provides the grounding of the static electricity built-in particularly in the metallic extension tube (2), to the floor being cleaned over a contact surface (9) provided at the base of the brush (4).
• a contact surface (9) provided at the base of the brush (4).
• one or more conductive rings (7) and one or more conductive wires (5) placed on the connection surfaces between the brush (4) and the extension tube (2) are used.
• Said wires (5) connect the rings (7) with other rings (7) or with the contact plate (9).
• said ring (7) and wire (5) are produced and used as one piece.
• said ring (7) and wire (5) are used as two distinct parts and joined to each other for example by soldering during their assembly.
• Said wire (5) is preferably placed into one or more channels (6) opened on the support piece.
• one or more shields (14) are used to protect it.
• Said ring (7) is placed in one or more suitable recesses (8) opened on the extension tube (2) and/or brush (4). It can easily be kept in contact with another ring (7) or with the conductive surface of the extension tube (2), by virtue of its hollow cylindrical structure, while the extension tube (2) and the brush (4) are removable fitted to each other. More than one ring (7) in contact with each other and placed preferably on both contacting surfaces, is used in order to prevent the torsions occurred during mounting/dismantling from detaching the connection between the ring (7) and the wire (5).
• the rings (7) used at different parts such as the extension tube (2) and the brush (4) have dimensions corresponding to the surface they are intended to be placed.
• Said rings (7) are placed in the recess (8) on the inner surface of large pieces and on the outer surface of the small pieces.
• the electrostatic charge has to be conducted to the base of the brush (4) over the conductors (5) continuously, i.e. always keeping the contract at connection points.
• the contact surface (9) at the base of the brush (4), in contract with the floor, such as a metal plate, screw, and the like, enables the grounding of the electrostatic charge. Grounding continues until the electrostatic charges in these objects are brought to equal quantities. In this way, the high amount of electrical charge, built-up during the use of the vacuum cleaner is transferred to the surface being cleaned, without affecting the user.
• one or more projections (13) on the ring (7) which present said ring (7) from moving by being attached on the place they are situated, are used so that the connection between said ring (7) and the wire (5) is not detached as the result of torsions.
• groimding is provided without being influenced by the continuous contact of the ring (7) and the wire, by the movements of the components such as the extension tube (2) and brush (4) they are placed on, and/or by their being removably mounted; and the user health is protected.
• the vacuum cleaner (1) comprises an elbow (3) which provides the connection between the brush (4) and the extension tube (2), and which is attached to the brush (4) and used together.
• the elbow (3) when the elbow (3) is made of a conducting material, it serves as a conductor between the extension tube (2) and the brush (4). Grounding is realized over the contact surface (9) by means of a ring (7) and a wire (5) placed only on the brush (4).
• the elbow (3) is made of a non-conductive material, grounding is provided over the contact surface (9), by means of the ring (7) and the wire (5) placed on it, by conducting the electrostatic charge on the extension tube (2) to said ring (7) and wire (5) on the brush (4).
