Definitions

  • This invention relates to apparatus for removing liquid from a moving airflow and has been devised particularly though not solely for use in the vacuum conduit of a vacuum cleaner for removing any liquid present in the airflow in the vacuum cleaner conduit.
  • vacuum cleaners which are capable of being used to remove liquids as well as solids such as dirt or dust particles from surfaces have had an air/liquid separation device incorporated within the vacuum cleaner.
  • a separation device is necessary to prevent liquid damaging the vacuum cleaner by entering the electric motor or the dust filter of the machine.
  • a vacuum cleaning machine which is specifically designed for use with liquids.
  • the invention may be said to consist in apparatus for removing liquid from an airflow, said apparatus comprising: a chamber having an inlet for an incoming airflow comprising a mixture of air and liquid to enter said chamber, said incoming airflow being produced by the vacuum of a vacuum cleaning machine, an outlet for an outgoing airflow comprising said incoming airflow with said liquid substantially removed therefrom to exit said chamber, said outlet being adapted to be connected to an end of a conduit so as to be in fluid communication therewith, said conduit being in fluid communication with said vacuum cleaning machine, and a liquid collection area for collection of said liquid.
  • the invention consists in the foregoing and also envisages constructions of which the following gives examples. BRIEF DESCRIPTION OF DRAWINGS
  • Figure 1 is an elevation in cross-section of apparatus in accordance with the present invention for removing liquid from an airflow
  • Figure 2 is a schematic diagram of the apparatus of Figure 1 in use with a vacuum cleaner
  • Figure 3 is an elevation in cross-section of an alternative apparatus for removing liquid from an airflow in accordance with the present invention.
  • Figure 4 is an elevation in cross-section of another alternative, and preferred apparatus for removing liquid from an airflow in accordance with the present invention.
  • apparatus for removing liquid from an airflow is shown generally referenced 1.
  • the apparatus comprises a chamber 2 having an inlet 4 and an outlet 6.
  • the chamber comprises two separate portions 8 and 10, the portions having corresponding threaded surfaces 12 so that they may be selectively fitted together to provide a substantially air tight and water tight engagement or be separated from each other by a user.
  • the inlet 4 is provided some distance above the base 14 of the chamber and the inlet 4 has a baffle 16 located adjacent thereto, the baffle 16 being dependent from the inlet 4 by support members 18.
  • the support members 18 have substantial gaps therebetween to allow airflow into the chamber 2.
  • the inlet 4 is part of a hose or conduit attachment tube 20 for attachment to a vacuum cleaner conduit such as a flexible conduit which has the nozzle or matter, such as dust or dirt, gathering portion at the other end thereof.
  • the outlet 6 of the chamber is part of a conduit connection tube 22 for connecting to a flexible vacuum cleaner conduit the other end of which is connected to the vacuum cleaner machine so as to be in fluid communication therewith.
  • conduit 27 need not be provided so that the water removal apparatus 1 is provided rigidly connected to or as part of nozzle 29.
  • the apparatus 1 could be adapted to be plugged directly into a wall connection so as to be held thereby and the conduit 27 could be used to flexibly connect the nozzle 29 to the apparatus 1.
  • the apparatus 1 could be provided as part of nozzle 29 and the other end of conduit 27 adapted to connect to the wall connection socket.
  • the airflow from the nozzle portion of the conduit enters the chamber 2 through tube 20 and inlet 4 as indicated by arrows 24.
  • the airflow is then deflected off baffle 16 in a downward direction indicated by arrows 26 after which it proceeds relatively slowly upwardly as shown by arrows 28 and exits the chamber in direction shown by arrows 30.
  • liquid such as water for example is present in the 10 incoming air stream then as the air stream is directed through the indirect or tortuous path formed by the baffle 16, the velocity of the flow will decrease.
  • the baffle is designed to decrease the airflow velocity as shown by arrows 28 to a velocity below the carrying velocity, or minimum velocity required for carrying liquid, of the airflow.
  • the present invention may be used in the hose or conduit of a vacuum cleaner to clean up liquid spills or to use liquid to clean surfaces or objects and remove the cleaning liquid and dirt from the surface or object.
  • a float 34 may be provided in the form of an annulus having a wall 36 dependent therefrom. The float 34 is located about the outer surface of tube 20 on the inside of chamber 2 and is able to slide up and down the outer surface of tube 20 in response to the water level within the chamber.
  • the cylindrical surface 30 36 of the float 34 makes contact with the upper surface 38 of baffle 16 so as to impede the airflow entering the chamber and thus prevent the water level from rising any further.
  • the body 34 of the float could be used to block airflow between the baffle 16 and the outer surface of the portion of tube 20 within the chamber 2.
  • the supports 18 are designed so as not to interfere with walls 36 of the float.
  • the float could also be designed to block airflow through the outer instead, or both the inlet and outlet.
  • a "cyclone" form of separation device could also be used, that is, a separator which uses a spiral airflow through the chamber to separate the liquid from the airflow.
  • separator which uses a spiral airflow through the chamber to separate the liquid from the airflow.
  • Many other forms of separator could be used, but they must be adapted to be connected to a conduit of a vacuum cleaning machine for supply of substantially dry air to the conduit of the vacuum cleaning machine.
  • the baffle means 16 is connected to the annular float 34 by webs 40 which have spaces therebetween in order to allow the airflow to pass between the baffle 16 and float 34 as shown by arrow 28.
  • the upper surface 17 of the baffle 16 is in contact with a spring loaded, or otherwise biased, seal 42 which is maintained in sealing contact with surface 17 by a spring 44 for example.
  • the sealing surface of seal 42 has an aperture 46 therein the upper end of which is open to ball housing 48 which supports a ball 50.
  • the operation of the device described with reference to Figure 3 is as follows.
  • air or a mixture of air and liquids and/or particles of dust or dirt enters the device as shown by arrows 24 through the central tubular portion and the flow is deflected by the upper surface 17 of baffle 16 so that it enters chamber 2 at inlet 4 and substantially reverses direction as shown by arrow 26.
  • the indirect, or torturous flow path created by the baffle means 16 substantially removes the liquid from the airflow.
  • the liquid pools and collects in the base of the chamber as indicated by area 32 and the airflow turns and moves upward as shown by arrow 28, flowing about the outer surface of the baffle, then over the baffle and then out the outlet 6 after flowing through gaps 52 in the ball housing 48.
  • float 34 When the water level 32 reaches a undesirably high level, for example when the water level starts to approach the level of the inlet or any other undesirably high level, then float 34 will either lift or pivot slightly, which will move the baffle means 16 slightly, overcoming the force exerted by spring 44 on seal 42. This will break the seal between the upper surface 17 and the seal 42 so that air in the chamber 2, which has had liquid removed therefrom, will enter the aperture 46 in the seal member 42 and the airflow through the aperture 46 will tend to force the ball 50 upwardly slightly relative to the housing 48. The slight upward movement of the ball 50 is sufficient to push the ball into the rapidly moving airstream through the ball housing indicated by arrow 54.
  • FIG 4 a further, and most preferred, form of separation device is shown.
  • the device shown in Figure 4 is similar to the device described with reference to Figure 3, and the same reference numerals have been used to designate similar features of the separation devices shown in both Figures 3 and 4.
  • the baffle 16 is shown together with two other baffles or separators 60 and 62.
  • the baffle 16 comprises a first baffle, baffle 60 a second baffle and baffle 62 a third baffle.
  • the first baffle 16 is located adjacent to inlet 4 and spaced therefrom by support members 18 which have gaps therebetween in order to allow air to enter the device.
  • the second baffle member 60 is located immediately below first baffle member 16 and is also located adjacent to inlet 4 and dependent therefrom.
  • the float 34 is fixedly connected to valve actuating member 64 at point 66. Valve actuating member 64 rests on a ledge 68 in the walls of the chamber.
  • the valve 70 (comprising a further valve member) is pivotally mounted on the valve actuating member 64 at pivot 71.
  • the valve 70 When the valve 70 is in the position shown in Figure 4 it makes a substantially air tight seal with aperture 72 in third baffle member 62 which also contains the valve body or housing 48 for the ball valve member 50 of the valve means.
  • the third baffle member 62 has vertically disposed support members 74 which allow air to travel through the baffle member and into gaps 52 in the ball housing to travel out the outlet 6.
  • the device is connected to the vacuum cleaner as shown in Figure 2 for example, and then the vacuum of the vacuum cleaning machine air or a mixture of air and liquids and/or particles of dust or dirt enters the device as shown by arrows 24 through the central tubular portion.
  • the flow is deflected by the first baffle member 16 past support members 18 and in a downward direction as shown by arrows 26.
  • the second baffle member 60 then causes the flow of air and liquids to travel horizontally toward the outer walls 8 of the chamber as shown by arrows 28.
  • the rapidly moving airflow 28 impinges upon walls 8 and in so doing causes the liquids to separate from the airflow by accumulating on walls 8 and running downwardly together as liquid 32 in the base of the chamber.
  • a venturi effect occurs between the first deflector or baffle member 16 and float 34.
  • This venturi effect creates a reduction in air pressure adjacent to the outer edge of baffle 16 and thus causes a flow of air to be drawn up from the base of the chamber in the direction indicated by arrow 76 which assists in causing the liquid which has impinged upon walls 8 of the chamber to travel to the base of the chamber along with any air and liquid which is not separated out as indicated by arrow 78.
  • an annular ring 77 is provided dependent from valve actuating member 64. Airflow about the annular ring 77 creates a positive air pressure on an upper surface of float 34. This stabiHses the float, reducing the possibility of unnecessary actuation of ball valve 50.
  • the float 34 will also prevent operation of the device if the water level is sufficiently high so that when the apparatus is tilted on its side the float is caused to move. If there is very little liquid in the chamber and the unit lies on its side, then the float pivots about the ledge 68 to operate the air diversion member 64 and therefore cause operation of the apparatus to cease. Furthermore, if the apparatus is to pass the point where its longitudinal axis is substantially horizontal, the ball 50 will roll downwardly to seal against the outlet 6 so as to prevent any water which may be in the chamber from passing through the outlet and into the vacuum cleaner machine.
  • a device which is easily adaptable for location in the hose of conventional vacuum cleaner so as to allow liquids to be vacuumed using a conventional vacuum cleaner, the liquid being removed from the airflow by the device so as to prevent any liquid entering the pump, motor or dust receptacle of the vacuum cleaner.

Abstract

Dispositif de séparation air/liquide accouplé au conduit flexible d'un aspirateur. Le dispositif permet à l'aspirateur qui remplit sa fonction de nettoyage en créant une circulation d'air à travers le conduit flexible, d'aspirer des liquides ou de nettoyer des surfaces auxquelles on a appliqué un agent de nettoyage liquide, par exemple. Le séparateur sépare le liquide de l'air en circulation, de manière à ne pas faire pénétrer le liquide dans le conduit et à ne pas endommager l'aspirateur. Le séparateur possède également un clapet empêchant le liquide séparé de pénétrer dans le conduit.
