Definitions
- the present invention relates generally to the field of hand drying, and in particular to arrangements which use an air-knife to dry the hands.
- Warm air hand dryers are very well known. They are invariably low flow, low speed machines which rely on heating the air to promote an evaporative drying effect at the surface of the hand. Examples include the Model A Series of hand dryers manufactured and marketed by World Dryer Corporation. The heated airflow is typically discharged through a single nozzle and the drying action is a "hand-over-hand" action, requiring the user to rub the hands together under the nozzle with the aim of encouraging the evaporative drying effect.
- High speed hand dryers use high speed airflow (>80 m/s) to provide a momentum-drying effect at the surface of the hands.
- Examples include the Xlerator® hand dryer manufactured and marketed by Excel Dryer Inc. Again the airflow is typically discharged through a single relatively large nozzle and the mode of use is somewhat similar to the "hand-over-hand" action of the warm air dryer, with the hands being held or cupped together underneath the nozzle to dry them. However, instead of being evaporated, the vast majority of the water on the surface of the hands is instead driven or blasted from the hands by the high-momentum airflow, with evaporation accounting for only a small proportion of water removal. The airflow tends not to be heated, though waste heat from the motor may in some cases be used to heat the airflow to a degree.
- the third general type of hand dryer is the air-knife hand dryer, examples of which include the Dyson Airblade range of Hand Dryers manufactured by Dyson (UK) Limited and the Jet Towel hand dryer manufactured by Mitsubishi Electric Corporation.
- the air knives are discharged through narrow, continuous slots (only the rear slot a is visible in Figure 1 ), each less than 1mm wide.
- the air-knife is instead discharged through opposing rows of individual discharge apertures (only the rear row b is visible in Figure 2 ): here, the individual jets combine to produce the air knife downstream of the discharge apertures.
- the air knife is discharged at high speed (>80 m/s) to provide for an efficient wiping action across the surface of the hand.
- JP2006304926 is a bathroom-sink-integrated hand dryer having a water spout for spouting washing water, an air nozzle near the water spout for compulsorily drying the moisture of the washed hands with hot air, a hand-wash space for drying hands and an air blowing communication chamber with the air nozzle above a basin for washing and drying hands.
- the hand dryer also has a fan motor for feeding air to the air blowing communication chamber under the basin, and the duct for connecting the air blowing communication chamber and the fan motor.
- a heater is disposed inside the air blowing communication chamber.
- WO2011/074018 discloses a fixture according to preamble of claim 1.
- the present invention is concerned with air-knife hand dryers.
- a fixture according to claim 1 One of the problems identified with air-knife dryers is that of managing the disposal of waste water. This is a particular problem for air-knife dryers because the nature of the air-knife drying mechanism means that the water removal is non-evaporative: instead, the water is driven from the hands by the relatively high momentum of the airflow. In the conventional air-knife dryer arrangements described above, the waste water removed from the hands may be collected in a drip tray - which must periodically be emptied - or else is not collected at all and instead simply allowed to evaporate from surfaces on and around the dryer. Neither scheme is particularly hygienic.
- the invention advantageously makes use of the existing mains drainage system to manage the waste water more effectively: by incorporating the air-knife dryer on a fixture for a sink so that water driven from the hands can simply drain to mains through the standard drain-hole in the basin of the sink.
- the air-knife discharge outlets are not provided in a sidewall of the air duct. Instead, the air-knife discharge outlets extend across the second end of the air duct.
- This offers a simple air-feed configuration, in which the air is fed axially along the air duct in generally parallel alignment with the principal exit direction of the air-knife.
- the fixture can be positioned at the back of the basin of the sink - the commonplace position for sink fixtures - to direct the air-knife forwardly towards the user. This is achieved without having to turn the airflow inside the fixture, which would introduce losses and create noise.
- Each air-knife outlet may comprise an elongate discharge aperture or elongate line of discharge apertures.
- each air-knife outlet comprises an elongate air slot or plurality of elongate air slots.
- the slot, or air slots may be less than 2mm wide, intended to provide a laminar, well-defined air knife with minimal wind shear.
- the elongate air-knife outlets may be at least 80mm long, intended to span the width of a typical user's hand. A preferred range of lengths is 110mm to 150mm.
- the fixture comprises two elongate air-knife discharge outlets - one for each hand, the discharge outletsbeing arranged to extend laterally either side of the water nozzle.
- Figures 3-5 show an arrangement comprising a fixture 1 in combination with a sink 3.
- the sink 3 may itself be conventional. A "Belfast-type" sink is shown, though other types of sink may alternatively be used.
- the sink 3 has a standard drain-hole 3a, in this case positioned towards the rear wall of the basin 3b of the sink 3 ( Figure 4 ).
- the fixture 1 is fitted next to the basin 3b of the sink 3 using a locknut 5 underneath the sink 3 which engages with an externally threaded, hollow fixing stud 7 to clamp the fixture 1 in place (the fixture 1 may alternatively be fitted adjacent the sink rather than to the sink itself, according to the style of sink).
- the fixture 1 comprises a hollow, curved spout 9 which projects out over the basin 3b of the sink 3.
- the spout 9 has a rectangular cross-section, defined by opposing pairs of side walls 9a, 9b.
- the inside of the spout 9 forms an air duct 11, shown in Figure 4 .
- This air duct 11 has a first end 11a and a second end 11b.
- the air duct 11 is connected at the first end 11a to the hollow fixing stud 7.
- the second end 11b being the end positioned over the sink basin 3b in use, is provided with two air-knife discharge outlets: a left-hand air-knife discharge outlet 13 and a right-hand air-knife discharge outlet 15.
- Each air-knife discharge outlet 13, 15 extend laterally across the second end 11b of the air duct 11.
- Each air-knife discharge outlet 13, 15 takes the form of an elongate narrow air slot, less than 2mm in width - intended to provide a narrow, well-defined air-knife, and more than 80mm in length - intended to span the width of a typical user's hand.
- the hollow fixing stud 7 is connected to a motor-driven fan 17 via a flexible hose 19.
- the fan 17 is configured in use to drive airflow in through the air duct 11 - via the hose 19 and hollow fixing stud 7 - and out through the air-knife discharge outlets 13, 15 at a speed in excess of 80 m/s. The airflow is thus discharged from the outlets in the form of two high-speed air-knives.
- a water nozzle 21 is provided on the fixture 1, positioned in between the two air-knife discharge outlets 13, 15 so that the outlets extend laterally either side of the central water nozzle 21.
- the water nozzle 21 connects to the mains water supply line via a flexible pipe 23 which runs through the inside of the air duct 11 and out through the hollow fixing stud 7 (adequate provision will need to be made to route this pipe externally of the air supply line - or alternatively the flexible water pipe may run externally of the air supply line altogether).
- the fixture 1 On demand, water is delivered through the water nozzle 21 for washing.
- the fixture 1 is configured for "hands-free" operation to supply the water, using a conventional sensor and control loop which automatically opens a stop valve in the supply line, in response to detection of a user's hands in a washing position.
- the fixture 1 may be configured for manual operation to supply water.
- air-knives 13a, 15a are ejected through the air-knife outlets 13, 15 to dry the user's hands. Again, this is achieved via a conventional sensor and control loop, which automatically switches on the fan 17 in response to detection of a user's hands in a drying position (which should be distinguishable from the aforementioned washing position - which automatically activates the water supply).
- the fixture may be configured for manual operation.
- a user presents his (or her) wet left-hand - palm open - in front of the left-hand air-knife discharge outlet 13 and similarly presents his wet right hand - palm open - in front of the right-hand air-knife outlet 15 on the right hand of the spout 9.
- the sensor and control loop then operates to activate the fan 17, which forces air under high pressure through the air-knife outlets 13, 15: directing two high-momentum air-knives forwards onto the user's hands.
- the hands are dried one side at a time: first, the user passes his hands lengthwise up and down in front of the air-knife outlets 13, 15 with the back of the hand facing the air-knife outlets (referred to below as the "standard pass” - illustrated in Figure 6 ). Then - after turning over the hands - the user passes his (or her) hands lengthwise up and down in front of the air-knife outlets 13, 15 with the palms facing the air-knife outlets (referred to below as the "reverse pass”).
- the "standard pass” and “reverse pass” may each be repeated, as required, and carried out in any order.
- FIG. 7 shows an alternative arrangement in which the fixture 10 is wall-mounted above the sink 3, rather than being fitted next to the basin 3b of the sink 2.
- a relatively narrow, tubular spout 90 forms the air duct 110 connecting the fan to the air-knife discharge outlets (not visible: on the underside of the spout 90), and the outlets are provided extending across a flared forward end 110a of the air duct 110.
- Two outlets are provided, which deliver respective air-knives 130a and 150a.
- the water nozzle (not visible on the underside of the spout 90) is provided between the air-knife discharge outlets to deliver a stream of water 210a, via a flexible pipe 230 running inside the air duct 110.
- air-slots are not essential.
- the air knife discharge outlets may be formed from a line of air-holes or individual, shorter air slots - similar to the Mitsibishi scheme shown in Figure 2 .

Description
- The present invention relates generally to the field of hand drying, and in particular to arrangements which use an air-knife to dry the hands.
- In commercial washrooms, it is common to provide one or more sinks or water basins for washing, and one or more separate, wall-mounted hand-dryers which users can then use to dry their hands.
- There are three distinct types of hand dryer on the market: "warm-air" hand dryers, "high speed" hand dryers and "air-knife" hand dryers.
- Warm air hand dryers are very well known. They are invariably low flow, low speed machines which rely on heating the air to promote an evaporative drying effect at the surface of the hand. Examples include the Model A Series of hand dryers manufactured and marketed by World Dryer Corporation. The heated airflow is typically discharged through a single nozzle and the drying action is a "hand-over-hand" action, requiring the user to rub the hands together under the nozzle with the aim of encouraging the evaporative drying effect.
- High speed hand dryers, as the name suggests, use high speed airflow (>80 m/s) to provide a momentum-drying effect at the surface of the hands. Examples include the Xlerator® hand dryer manufactured and marketed by Excel Dryer Inc. Again the airflow is typically discharged through a single relatively large nozzle and the mode of use is somewhat similar to the "hand-over-hand" action of the warm air dryer, with the hands being held or cupped together underneath the nozzle to dry them. However, instead of being evaporated, the vast majority of the water on the surface of the hands is instead driven or blasted from the hands by the high-momentum airflow, with evaporation accounting for only a small proportion of water removal. The airflow tends not to be heated, though waste heat from the motor may in some cases be used to heat the airflow to a degree.
- The third general type of hand dryer is the air-knife hand dryer, examples of which include the Dyson Airblade range of Hand Dryers manufactured by Dyson (UK) Limited and the Jet Towel hand dryer manufactured by Mitsubishi Electric Corporation.
- These hand dryers use an air-knife - a sheet or curtain of moving air - to remove the water from the user's hands. The mode of operation is analogous to the established use of air knives in industry to remove debris or liquid from the surface of a product (see e.g.
EP2394123A1 , which describes removal of debris from a glass sheet using air knives): the air-knife moves across the surface of the hand and, as it does so, wipes or scrapes the water from the surface of the hand. - In both the Dyson Airblade and the Mitsubishi Jet Towel, two opposing, stationary air-knives are used, one for each side of the user's hand. The hands are inserted between the air-knives and then withdrawn slowly to effect the required relative movement between the hands and the air knives.
- In the Dyson arrangement - shown in
Figure 1 - the air knives are discharged through narrow, continuous slots (only the rear slot a is visible inFigure 1 ), each less than 1mm wide. In the Mitsubishi arrangement - shown inFigure 2 - the air-knife is instead discharged through opposing rows of individual discharge apertures (only the rear row b is visible inFigure 2 ): here, the individual jets combine to produce the air knife downstream of the discharge apertures. In each case, the air knife is discharged at high speed (>80 m/s) to provide for an efficient wiping action across the surface of the hand. - A further hand dryer is disclosed in
JP2006304926 -
WO2011/074018 discloses a fixture according to preamble ofclaim 1. The present invention is concerned with air-knife hand dryers. - According to the present invention, there is provided a fixture according to
claim 1. One of the problems identified with air-knife dryers is that of managing the disposal of waste water. This is a particular problem for air-knife dryers because the nature of the air-knife drying mechanism means that the water removal is non-evaporative: instead, the water is driven from the hands by the relatively high momentum of the airflow. In the conventional air-knife dryer arrangements described above, the waste water removed from the hands may be collected in a drip tray - which must periodically be emptied - or else is not collected at all and instead simply allowed to evaporate from surfaces on and around the dryer. Neither scheme is particularly hygienic. - The invention advantageously makes use of the existing mains drainage system to manage the waste water more effectively: by incorporating the air-knife dryer on a fixture for a sink so that water driven from the hands can simply drain to mains through the standard drain-hole in the basin of the sink.
- The air-knife discharge outlets are not provided in a sidewall of the air duct. Instead, the air-knife discharge outlets extend across the second end of the air duct. This offers a simple air-feed configuration, in which the air is fed axially along the air duct in generally parallel alignment with the principal exit direction of the air-knife. This means that the fixture can be positioned at the back of the basin of the sink - the commonplace position for sink fixtures - to direct the air-knife forwardly towards the user. This is achieved without having to turn the airflow inside the fixture, which would introduce losses and create noise.
- Each air-knife outlet may comprise an elongate discharge aperture or elongate line of discharge apertures. For example, each air-knife outlet comprises an elongate air slot or plurality of elongate air slots.
- The slot, or air slots, may be less than 2mm wide, intended to provide a laminar, well-defined air knife with minimal wind shear.
- The elongate air-knife outlets may be at least 80mm long, intended to span the width of a typical user's hand. A preferred range of lengths is 110mm to 150mm. The fixture comprises two elongate air-knife discharge outlets - one for each hand, the discharge outletsbeing arranged to extend laterally either side of the water nozzle.
