Definitions

  • This invention relates to a liquid atomizer for humiditying the air.
  • a duct is provided enclosing the exhausting hoods and attached on the upper side of a circular outside element of the atomizer unit, with an additional blower arranged opposite to the openings of the exhausting hoods for the production of an air stream to carry the mist.
  • FIG. l is a sectional view of the liquid atomizer
  • FIG. 2 is a plan view of the liquid atomizer according to FIG. l,
  • FIG. 3 is a plan view of a liquid atomizer with the air duct as a modied structure
  • FIG. 4 is a plan view of the liquid atomizer according to FIG. 3 with a joint drive for two blowers, and
  • FIG. 5 is a plan view showing a non-revolvable air channel and a wall.
  • a box or casing 2 is mounted as a support bracket.
  • the box 2 has on its upper side a circular opening 3, and on the bottom side of the box 2, there is an opening covered with a filter plate 4.
  • the filter plate 4 has a very tine mesh so that air streaming through it will be well cleaned.
  • a water container 5 to which has been attached a feed pipe 6 with a ioat valve 7 and a drainage pipe 8.
  • a motor driven centrifugal liquid atomizer unit 9 has been inserted with its circular outside element 20 into the opening 3 of the box 2 and has been rotatably mounted around an axis 33 in relation to the fixed box or casing 2.
  • the atomizer unit 9, which is of known design, has a suction pipe 10 extending into the water container 5, an opening 11 for the entry of air and two exhaust hoods 12 located in parallel, one beside the other (FIGS. l and 2).
  • Each exhaust hood 12 has two openings 13 and 14, FIGS. l and 2.
  • a duct 21 On the upper side of the circular outer rim element 20 of the unit 9, a duct 21 has been attached, consisting of side walls 22 and 23, a bottom plate 24, a cover plate 25 and of a rear end wall 26, FIGS. 1 and 2.
  • the exhaust 3,365,862 Patented Jan. 30, 1968 hoods 12 are entirely enclosed by the duct 21 and there is only one open front wall 27 of the duct 21.
  • an additional blower 28 is provided which has been placed between the end wall 26 and a distributor 29 which will let the air pass therethrough.
  • the wall 29 may consist of a grid or screen or of a metal sheet equipped with openings and it serves for an even distribution of the air that is forced therethrough, by the blower 28.
  • the air current moved by the blowers 28 because the metal sheets 22, 23, and 26 equipped with holes acts as coarse iiller, and moves only through the duct 21, not through the atomizer unit 9.
  • the cross section of the openings in the wall 29, is greater than the space allowing the air to pass through the wall 26, so that an increase of air pressure cannot occur in the space between these two walls.
  • blower 19 of the unit 9 is provided for the blower 19 of the unit 9 and for the additional blower 28 arranged in the duct 21.
  • the blowers 19 and 28 can each be switched on separately, and if both blowers 19 and 28 are switched on, then the quantity of air moved by the blower 28 will be a multiple of the quantity of air moved by the blower 19.
  • the side walls 22 and 23 and the end wall 26 of the duct 21 will consist of a metal sheet with holes therein, serving as a coarse filter.
  • the side walls of the duct ⁇ 21 are fitted with double walls 23, 35, 22 and 34 and the additional side walls 34 and 35 run angularly in relation to one another.
  • the wheels of the additional blower 28 are located more closely, one near the other, and the air is sucked in in flow paths 30.
  • a wall 36 which will allow the air to pass through and which is equipped with means to distribute the air, is smaller than the wall 29 in FIGS. l and 2.
  • the other construction elements of the device according to FIG. 3 correspond to the device according to FIGS. l and 2.
  • the additional blower 28 has been connected by means of a belt 37 with the motor of the unit 9. Therefore, no separate motor is required for the blower 28.
  • the rear end wall 38 of the duct 21 merely has an opening 39 passing over into the Wall 1 and will be in connection with this opening 39, for example, with some other spaec or with the open air in order to have a supply of fresh air.
  • the unit 9 with their duct 21 can be swung around the axis 33, FIG. l, then it will be possible to blow the mist-air mixture, coming from the device, in various directions into a room or space.
  • the device which cannot be turned, according to FIG. 5 it is possible, for example, to suck in the fresher air of some other room through the fan ZS and to blow it in a humidiiied state into a room with air.
  • blower 28 and the blower 19 Because of the double air current, by means of the blower 28 and the blower 19, it will only be necessary for a small quantity of well purified air to flow through the unit 9, in order to produce a mist. About of the total air moved by the blowers 19 and 2S will come through blower 28 and will serve as a carrier for the mist coming from the unit 9. The 10% of the total air moved by the blower 19 will be very well purified because of the filter plate 4, which will result in a long life of the unit 9 because there will be little pollution.
  • An apparatus for humidifying air comprising a casing having vertical side walls and generally horizontal top and bottom walls, said top wall having a circular opening therein, a container supported within said casing in spaced relation to said casing walls, a motor driven centrifugal liquid atomizer unit rotatably supported on the rim of said circular opening, said unit having a vertical axis of rotation, said unit further comprising a housing including an open-ended portion extending downwardly into said casing adjacent said container and a hood portion extending upwardly from said opening, liquid atomizing and air moving means enclosed within and spaced from the walls of said housing, said atomizing means including a suction means adapted to extend into liquid in said container and including liquid atomizing elements adapted to disperse atomized liquid into the space between said atomizing means and the housing, an air inlet opening in the bottom wall of said casing, a filter completely spanning said inlet opening, a horizontal open-ended duct including an opening in the bottom wall thereof, said duct having substantially imperforate walls
