Definitions

  • This invention relates to an exhaust fan, more particularly to the drive of an exhaust fan.
  • Exhaust fans are commonly used in domestic situations, particularly for use in kitchens, bathrooms and toilets to remove not only fumes and odours, but also steam from baths and showers. They are also used in public buildings such as in the bathrooms and toilets of hotels, motels, and apartments. In the more humid areas, particularly in the tropical areas it known that these fans are positioned in the ceiling to exhaust into the roof space, or in an outside wall to exhaust directly outside of the building.
  • Units are known where provision is made for the extraction of air from toilets, and reference is made to AU-24999/84 which is directed to a ventilator for a lavatory pan, there being an electric fan having its inlet connected a duct extending from the cistern to the flush pipe of the pan.
  • a manual switch is operated to switch on the fan, there being a valve in the flush pipe which when the water flows opens, and when the flow of flush water ceases the valve returns to its closed position and in so doing operates the switch to turn off the fan.
  • AU14859/88 discloses a similar system with the switch being manually operated to turn on the fan, but the switch having a time delay to automatically turn off after a preset period of time.
  • a still further object of the invention is to provide an exhaust fan which is not so susceptible to the problems of rust and corrosion.
  • an exhaust fan driven by a water turbine connected to a water supply and a point of usage of the water so that whenever the water is used at the point of usage the exhaust fan operates.
  • the water is taken to the position of the fan in the building.
  • the water turbine is connected to the fan by a drive which ensures that the fan operates at a speed suitable for exhausting the air from the area concerned.
  • FIG. 1 is a diagrammatic view of the invention applied to a bathroom and a toilet
  • FIG. 2 is a view of the fan and drive unit
  • FIG. 3 is a sectional view of one form of water turbine, FIG. • ; a view of the rotor of a turbine,
  • FIG. 5 is a view of a further water turbine
  • FIG. 6 is a view of a further rotor of a turbine
  • FIG. 7 is a view of an axial flow turbine
  • FIG. 8 is a view of an impulse turbine
  • FIG. 9 is a view of a positive displacement motor.
  • FIG. 1 there is shown one example of the installation and use of the invention.
  • a bath room 1 having a shower 2 an: 5 a hand basin 3, and also a toilet 4 having a cistern 5 to supply water to a toilet pan 6.
  • a hot water supply 7 is provided to the shower 2, and it will be realised that there would also be a hot water supply (not shown) to the hand basin 3.
  • the bath room 1 is fitted with an exhaust fan 8 driven by a water turbine 9 while the toilet 4 is '. u ⁇ d with an exhaust fan 10 driven by a water turbine 11.
  • the cold water supply pipe 12 passes along the ceiling and is connected by branch pipe 13 to the inlet to the water turbine 9, the pipe 12 extending to the inlet to the water turbine 11.
  • the exhaust from water turbine 9 is connected by p.pe 14 to the cold water tap 15 of the hand basin 3, and is also connected by branch pipe 16 to tap 17 of the shower 2.
  • the exhaust from the turbine 11 is connected by pipe 18 to the inlet to the cistern 5.
  • FIG. 2 is a view of a combined exhaust fan 10 and water driven turbine 11 with the fan impeller 18 being direct coupled to the driving shaft 19 of the water turbine 11.
  • FIG. 3 shows in cross section one form of water turbine 20, the casing 21 having a water inlet 22 and a water outlet 23, the inlet 22 passing water axially to the rotor 24.
  • the rotor 24 can have a plurality of spiral passages extending from the centre of the rotor to the circumference thereof.
  • FIG. 4 shows one form of such rotor where the impeller 25 has the passages 26 extending from the central inlet 27.
  • FIG. 5 shows a further form of turbine where again the water inlet 28 is axial to the rotor 29, the curved or spiral passages 30 extending from the axial inlet to a radial and tangential discharge 31.
  • a still further form of rotor 32 is shown in FIG. 6, again the water entering axially and discharging tangentially of the rotor.
  • FIG. 7 shows in cross section an axial flow turbine 33 having an inlet 34 and exhaust 35.
  • the drive shaft 36 is attached to a rotor 37, the drive shaft being supported in a spider 38 and bearings 39.
  • the rotor 37 in this example is in the general form of a marine propeller.
  • impulse turbine 40 is shown in FIG. 8 in which a jet of water from the inlet 41 impinges on the curved blades 42 of the rotor 43, the water exhausting through outlet 44.
  • FIG. 9 An example of a positive displacement turbine 45 is shown in FIG. 9, the turbine having an inlet 46 and an outlet 47.
  • the rotor 48 has a plurality of sliding vanes 49 against which the water acts to 1 drive the turbine.
  • the exhaust fan can be driven by one of a number of water turbines. It will be appreciated that the exhaust fan can be positioned as desired in the room, either in the wall or in the ceiling, so that steam, water vapour and other gasses and odours are exhausted from the room.
  • the fan be direct coupled to the shaft of the.turbine, it is to be realised that in some instances there may be either a step-up drive or a step-down drive connection between the water turbine and the fan, depending on the turbine and the fan size.
  • the driving connection between the water turbine and the fan can be a belt drive or an enclosed gear train drive.
  • the cold water supply to each of these is from a single point of entry and passes through the water turbine before being branched to the various points of use. In this way irrespective of which of the unit uses cold water, the water turbine will operate to drive the exhaust fan.
  • the components of the water turbine and the fan can all be produced of a suitable plastics material, so that rust and corrosion can be eliminated.
  • the housing of the turbine and also the rotor itself can be produced of a plastics material, as can the fan blades and the surrounding casing and protective grill.

Abstract

Un ventilateur d'aération est entraîné par une turbine à eau. La turbine à eau est connectée entre l'alimentation en eau et le point d'utilisation, de sorte que lorsqu'on utilise de l'eau, par exemple une douche, une baignoire, des toilettes, le ventilateur est entraîné par la turbine à eau.
