  • the first hand washing station includes a basin supported by a countertop and a faucet supported by the countertop.
  • the lavatory system also includes a hand dryer including a housing supported by the countertop.
  • the housing defines a cavity in which a user's hands are inserted during drying, and a motor configured to generate blown air in the direction of the cavity.
  • the housing is located such that the user's hands may be inserted into the cavity without the user leaving the first hand washing station.
  • a lavatory wash station comprises a wash station housing, a sink basin connected to a front of the housing, wherein the sink basin has a rim; the wash station also includes a sanitizing hand dryer assembly having an air intake and an exit nozzle at the front of the housing, where the air intake is disposed at the front of the housing and the exit nozzle is disposed at the front of the housing above the rim, where the exit nozzle provides air flow in a substantially downward direction in the direction of the sink basin and the sanitizing hand dryer includes an ion generator that adds ions to the air passing through the hand dryer.

  • line power e.g. 120 VAC, 208 VAC, 220 VAC, 277 VAC, et cetera
  • the blower and air purification system are disposed within the housing 12, and includes an air flow conduit between the air intake 50 and the nozzle 52.
  • the air intake 50 may be disposed below the basin rim 30, for example, at a corner region of the housing front 20 adjacent to the housing bottom end 22 and the housing second side 28.
  • the filter is configured to filter air provided by the air intake 50 to the downstream air purification system and blower.
  • the nozzle 52 is disposed above the basin rim 30 and the faucet spout 41, at a corner region of the housing front 20 adjacent to the housing top end 24 and the housing second side 28.
  • the nozzle 52 directs air substantially vertically downward towards the sink hand drying section 34. This ensures that air from the dryer, which strikes the hand(s), flows primarily along the interior of the hand drying section inwardly towards the sink hand washing section 32.
  • the surface of the hand drying section 34 preferably slopes inwardly so water runs into the hand washing section, which contains the drain.
  • the sidewall 44 extends from the basin rim 30 to the dryer cover 46.
  • This provides separation for adjacent wash stations, as shown in FIGs. 2 and 3.
  • the dryer cover 46 is disposed a lateral distance from the automatic faucet 36, such that the faucet remains uncovered.
  • the air flow from the nozzle flows vertically downward towards the sink basin, so water removed from the hands of a user by the airflow is contained within the sink basin rather than falling onto the floor, onto another surface of the wash station, or over to an adjacent wash station.
  • FIG. 4 is a cross sectional illustration of the sink basin, including the hand washing section 32 and the hand drying section 34.
  • the primary airflow path from the nozzle (not shown) is illustrated by arrow 80.
  • the contours of the sections 32, 34 ensure that airflow moves along surfaces of the sink hand drying section 34 towards the sink hand washing section 32, taking water on the surfaces along with it.
  • the purification light 48 (e.g., a blue purification light) may be disposed on a bottom of the dryer cover 46.
  • the purification light 48 may illuminate and/or sanitize surfaces of the sidewall 44, the housing front 20 and/or the sink basin 14 in a region between the sink hand drying section 34 and the dryer cover 46. If the light merely illuminates, then the light may turn on when the dryer is discharging drying air, and turn off when the user has completed drying his hands.
  • the light 48 may also purify surfaces of the wash station struck by the light using visible and invisible wavelengths of light, including for example UV light. In this case the light may remain on for a period of time after the blower has stopped, in order to provide the desired purification/sanitizing.
  • the dryer sensor may be disposed proximate the nozzle 52.
  • the dryer sensor is configured to provide an "on" signal to the blower, the air purification system and/or the purification light when, for example, a hand is proximate the nozzle 52.
  • the wash station 10 may be configured as a modular unit 54 such that a plurality of the wash stations 10 can be connected together for use, for example, in a public restroom.

In contrast, in the embodiment illustrated in FIG. 1 the dryer cover 46 is located at a height above the faucet 36. One of ordinary skill will appreciate that the dryer cover may also be located at a height below the faucet.
  • FIG. 6 is a perspective pictorial view of a plurality of the alternative embodiment wash stations 70 configured as a modular unit 90 such that a plurality of the wash stations 70 are connected together for use, for example, in a public restroom.
  • Each modular unit 70 may also include a trash receptacle 92 having an opening 94 and a tissue dispenser 96.
  • each wash station 70 may include a display/logo 98 that illuminates when the dryer is discharging air.
  • the display 98 may be configured, for example, as a backlit sign that relays information regarding the manufacturer of the wash station 90, et cetera, or it may be a display presenting scores at an event, or any other information that a user may find of interest.
