Definitions

  • the present invention particularly relates to enhancing dust collection performance of a cleaning head used in vacuum cleaners.
  • Vacuum cleaners are appliances which have considerably low efficiencies. The portion of a vacuum cleaner's power utilized to clean dust from a surface is very low. Therefore, there is a need for vacuum cleaners functioning with much higher efficiency and having maximal dust collection capacity.
  • At least one suction port is provided on the base of the cleaning heads used in vacuum cleaners.
  • Channels are grooved on the base of the cleaning head, to provide an equal pressure distribution and a homogeneous suction throughout the base.
  • the dust collected from the surface is directed towards a suction port by means of the channels provided on the cleaning head base.
  • An equal and homogeneous suction is thus provided along the entire base of the cleaning head.
  • current vacuum cleaner cleaning heads comprise a single suction port. High vacuum pressure occurring during usage of vacuum cleaners with high suction power, causes the cleaning head to adhere to the surface and the user to fail performing an effective vacuum cleaning.
  • US 2006/000053 discloses a vacuum cleaner having a suction port.
  • US7,350,268 discloses a first and a second suction port provided on the same base of the cleaning head. The second port however is not directly connected via a second channel to the pipe but via a conduct to the main suction space which however is connected to the first suction inlet.
  • the aim of the present invention is to realize a vacuum cleaner in which the high vacuum pressure occurring between a surface and a cleaning head is homogenized.
  • the vacuum cleaner realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a first suction port and at least one second suction port provided on the base of a cleaning head, a first channel extending through the cleaning head to the pipe and directly connecting the first suction port to a pipe, and at least one second channel extending through the cleaning head to the pipe and directly connecting the second suction port to the pipe and further comprises at least one orifice interposed between the body side wall and the second suction port, at least one lid controlled by the user, enabling the orifice to be opened and closed, and a movement mechanism enabling actuating the lid.
  • the movement mechanism By means of the movement mechanism, the user opens and closes the orifice opening outside, and thereby performs an effective vacuum cleaning.
  • the user actuates the lid by means of the movement mechanism and enables closing the orifice.
  • the orifice is opened by actuating the lid again, preventing the cleaning head from adhering due to vacuum effect to the item to be vacuumed.
  • the movement mechanism enables the user to shift the lid placed on the second suction port, to open or closed position.
  • the second suction port is thus enabled to function efficiently.
  • the first suction port is preferably disposed in the middle of the cleaning head, and two second suction ports are provided on both sides of the first suction port. Problems related to usage difficulties are thus eliminated by homogenizing high vacuum effect on the cleaning head base by three separate suction ports in the vacuum cleaner cleaning head with an unmovable base.
  • the first channel is "L"-shaped and interconnects the first suction port and the pipe.
  • the second channel forms a corner in between when interconnecting the second suction port and the pipe.
  • the first and the second suction ports are annular.
  • the diameter of the suction ports is 5 cm.
  • the first and the second suction ports are rectangular.
  • the length of the shorter edges is 6 cm and the length of the longer edges is 7 cm.
  • the movement mechanism comprises a spring extending from beside the body of the cleaning head towards the second suction port, whose one end is fastened to the lid, a pusher enabling the spring to be compressed and released, whose one end is fastened to the spring, and a trigger to which the pusher is connected, shifting the lid to open or closed position by actuating the pusher and the spring upon being triggered by the user from beside the cleaning head.
  • the invention enables improving performance of the cleaning head and facilitates usage.
  • the invention reduces the high vacuum pressure which in fact makes usage more challenging.
  • the second channel enables achieving a homogeneous vacuum pressure distribution on the base by transmitting the vacuum effect between the cleaning head base and a surface not through a single channel but through the second channels. Said homogenizing eliminates the usage problems arising from vacuum pressure.
  • the present invention enables homogenizing vacuum pressure without modifying the size of current cleaning heads.
  • dust collection capability is enhanced by means of the cleaning head comprising three channels.
  • the first channel (7) is "L"-shaped and interconnects the first suction port (4) and the pipe (6).
  • the second channel (8) forms a corner in between when interconnecting the second suction port (5) and the pipe (6).
  • the first and the second suction ports (4 and 5) are rectangular.
  • the invention enables improving performance of the cleaning head (1) and facilitates usage.
  • the invention reduces the high vacuum pressure which in fact makes usage more challenging.
  • the second channel (8) enables achieving a homogeneous vacuum pressure distribution on the base (3) by transmitting the vacuum effect between the cleaning head (1) base (3) and a surface not through a single channel but through the second channels (8). Said homogenizing eliminates the usage problems arising from vacuum pressure.
  • the present invention enables homogenizing vacuum pressure without modifying the size of current cleaning heads (1).
  • dust collection capability is enhanced by means of the cleaning head (1) comprising three channels (7 and 8).
  • the first suction port (4) is preferably disposed in the middle of the cleaning head (1), and two second suction ports (5) are provided on both sides of the first suction port (4). Problems related to usage difficulties are thus eliminated by homogenizing high vacuum effect on the cleaning head (1) base (3) by three separate suction ports (4 and 5) in the vacuum cleaner cleaning head (1) with an unmovable base (3).
  • the first channel (7) is "L"-shaped and interconnects the first suction port (4) and the pipe (6).
  • the first and the second suction ports (4 and 5) are annular.
  • the movement mechanism (10) comprises a spring (11) extending from beside the body (2) of the cleaning head (1) towards the second suction port (5), placed in a cylindrical seat (15) with the orifice (14) on its end, whose one end is fastened to the lid (9); a pusher (12) enabling the spring (11) to be compressed and released, whose one end is fastened to the spring (11); and a trigger (13) to which the pusher (12) is connected, shifting the lid (9) to open or closed position by actuating the pusher (12) and the spring (11) upon being triggered by the user from beside the cleaning head (1).
  • Light items are enabled to be vacuum cleaned without adhesion to the cleaning head (1) by reaching atmospheric pressure by means of the orifice (14) opening to the second suction port (5) by the lid (9) being opened ( Figure 4 , Figure 5 and Figure 6 ).
