Definitions

  • the present invention relates to a blind cleaner device.
  • Window blinds are commonly installed in various spaces, such as commercial buildings or a residential space as part of an interior decoration of such spaces.
  • the window blinds are used to regulate an amount of desired light in the space where they are installed. Further, the window blinds may block direct sunlight, promote energy conservation, and provide privacy.
  • the window blinds typically consist of multiple lamellae that are arranged in parallel.
  • the lamellae are spaced apart from each other by a predefined distance.
  • a number of controlling means are provided for controlling an angular position of the lamellae of the window blinds, such that the lamellae may be angularly rotated between an open position, which permits maximum passage of light through the window blinds, and a closed position, which provides maximum blockage of light through the window blinds.
  • dirt, dust, debris, particulate matter, and the like may accumulate on the window blinds.
  • pathogens may also be present on the window blinds.
  • such window blinds may have to be periodically cleaned. In applications where a large number of window blinds are installed, such as in the commercial buildings, individual cleaning of each lamella becomes a time consuming and laborious task.
  • Some cleaning devices such as brushes, are available in the market to remove particles accumulated on the lamellae of the window blinds. These brushes typical use a friction surface and/or a vacuum to dislodge particles accumulated on the lamellae of the window blinds. However, some particles are well adhered to the surfaces of the lamellae which may be difficult to remove with such brushes. In some cases, greasy residues are needed to be removed from the lamellae. Further, particles accumulated on the lamellae of the window blinds tend to adhere to the greasy residues. Such greasy residues may not be completely removed with brushes that involve techniques such as friction and/or vacuum. Furthermore, conventional modular design of the blind cleaner device may include a number of opening on a body of the blind cleaner device.
  • a fluid (say water) used in the blind cleaner device may come out through these openings.
  • a sealing arrangement may be required to seal the openings on the body.
  • the '625 reference discloses a cleaning apparatus, more particularly the '625 reference discloses a portable hand-held cleaner.
  • the portable hand-held cleaner includes a number of brush-type cleaning members.
  • the brush-type cleaning members are adjustable relative to one another. Further, a working fluid may be supplied to the portable hand-held cleaner. Furthermore, the brush-type cleaning members may be driven to make a cleaning movement.
  • the portable hand-held cleaner of '625 reference includes multiple parts and openings that are complex in design and assembly. Further, the present reference does not seem to provide any sealing arrangement or means to seal the openings. Furthermore, the portable hand-held cleaner seems cumbersome to use during cleaning process.
  • the blind cleaner device includes a body defining one or more openings.
  • the blind cleaner device also includes a cover attached with the body of the blind cleaner device.
  • the blind cleaner device is characterized in that the cover includes one or more sealing plugs. Each of the one or more sealing plugs of the cover water-proofing plug a corresponding opening of the one or more openings of the body.
  • the present invention provides an improved blind cleaner device to clean the lamellae of window blinds effectively and efficiently.
  • the blind cleaner device includes the sealing plugs which are integrated with the cover which reduces the number/quantity of parts in the blind cleaner device. Further, this arrangement prevents instances involving loss or misplacement of the sealing plugs as the sealing plugs are integrated part of the cover. It should be noted that the blind cleaner device can be used for cleaning other components apart from window blinds, as applicable.
  • each of the one or more sealing plugs further includes an O-ring seal to plug the corresponding opening of the one or more openings.
  • the O-ring seal may properly seal the corresponding opening to avoid leakage of cleaning fluid therethrough.
  • the one or more sealing plugs close one or more holes of nozzles of the blind cleaner device.
  • the sealing plugs close the holes of nozzles to provide implementation benefits such as to prevent discharge of cleaning fluid therethrough.
  • the cover includes a first portion and two second portions substantially perpendicular to the first portion.
  • the first portion and the two second portions forms a substantially U-shaped structure which provides structural rigidity and robustness to the blind cleaner device.
  • the first portion includes the sealing plugs.
  • the disposition of the sealing plugs on the first portion of the cover may allow desired alignment and easy insertion of the sealing plugs into the openings.
  • FIG. 1 is a perspective view of a blind cleaner device 100.
  • the blind cleaner device 100 may be used for different cleaning applications, such as to clean a number of lamellae (not shown) of a window blind (not shown).
  • the blind cleaner device 100 includes a fluid supply device 102.
  • the fluid supply device 102 includes an actuator 104 to allow passage of the fluid towards a body 106 of the blind cleaner device 100.
  • the fluid supply device 102 may include any arrangement for passage of the fluid towards the body 106 of the blind cleaner device 100, such as button, knob, handle, and the like.
  • the fluid supply device 102 includes a first inlet 108 (as shown in FIG. 3 ) and a first outlet 110 (as shown in FIG. 3 ).
  • a hose connector 112 is removably attached to the fluid supply device 102.
  • the hose connector 112 is removably attached to the first inlet 108 of the fluid supply device 102.
  • the hose connector 112 includes a threaded section (not shown) to removably couple a hose pipe (not shown) with the hose connector 112.
  • the hose pipe may supply the fluid from a fluid connection (not shown) towards the blind cleaner device 100.

  • the rotatable joint 116 In a vertical position (as shown in FIG. 1 to FIG. 3 ), the rotatable joint 116 allows vertical coupling of the fluid supply device 102 with the body 106 of the blind cleaner device 100. The vertical position of the fluid supply device 102 may create less disturbance for the user during the cleaning operation. In a horizontal position (not shown), the rotatable joint 116 allows horizontal coupling of the fluid supply device 102 with the body 106 of the blind cleaner device 100. In the horizontal position of the fluid supply device 102, the user may feel less weight, pressure or shocks during a cleaning operation.
  • FIG. 3 shows the blind cleaning device 100, in accordance with an embodiment of the present invention.

  • the outlet channels 131 are substantially perpendicular to the inlet channel 129.
  • the inlet channel 129 is fluidly coupled to the inlet portion 118 of the body 106 for a fluid flow "F", such as water for cleaning, therethrough. Further, the outlet channels 131, receive the fluid flow "F” from the inlet channel 129 to supply the fluid flow "F” to each bristle plate 132, 134.
  • Each bristle plate 132,134 defines an inlet opening 135 and a number of fluid nozzles 130.
  • the fluid flow "F" from the outlet channels 131 of the distributor 127 enters the bristle plates 132, 134 through the inlet opening 135. Further, the fluid flow "F” is discharged through the fluid nozzles 130, such as for applications involving cleaning of the lamella of the window blind and the like.
  • the present invention refers to the "fluid” or the "fluid flow” which have been used interchangeably for ease of explanation and understanding.
  • the fluid flow “F” through the blind cleaner device 100 is illustrated in FIG. 3 for detail flow from the hose connector 112 to a fluid supply device 102, and then to the distributor 127 of the body 106. This fluid flow “F” then splits in the distributor 127 to move towards each bristle plate 132, 134, as illustrated in FIG. 3 .
  • the blind cleaner device 100 further includes an adjustable limitation stop 120 for different lamella width.
  • the limitation stop 120 may be integrated and work with the distributor 127 to allow splitting of water from the inlet channel 129 to the outlet channels 131.
  • the blind cleaning device 100 may not include any limitation stop 122 and make application of the distributor 127.
  • the limitation stop 120 includes a cylindrical body defining an inlet (not shown) and an outlet (not shown).
