This invention relates to lavatory fixtures.
More particularly, the present invention relates to hand drying devices used in association with sinks bathroom vanities and facilities.
BACKGROUND OF THE INVENTIONIn the field bathroom fixtures, there have been numerous attempts to provide devices for drying hands after washing. These devices conventionally included towel dispensers and the like, which result in large amounts of waste and must be replaced frequently. Additionally, if positioned on a wall away from the basin, trails of dripping water are left to cause an untidy appearance if not dangerously slippery conditions on the flooring. To overcome these problems, air blowers were introduced which use forced air to strip water off the hands presented to be dried. While somewhat effective in eliminating waste, and requiring replacement of towels, these devices still require movement of the user from the basin to the drying device, resulting in dripping and dispersion of water. Attempts at solving this last problem include mounting an air blower next to the faucet so the hands can be dried after washing without moving. While somewhat successful, no dripping on the floor, the blowers simply expel the water off the hands and onto the person. Additionally, these devices are aesthetically displeasing, awkward, and clutter counter space. It would be highly advantageous, therefore, to remedy the foregoing and other deficiencies inherent in the prior art.
An object of the present invention is to provide an air blowing hand dryer in association with a sink basin.
Another object of the present invention is to provide a non-obtrusive hand dryer.
Yet another object of the present invention is to provide a hand dryer which expels water away from the individual using the device.
SUMMARY OF THE INVENTIONBriefly, to achieve the desired objects and advantages of the instant invention, provided is a nozzle fixture for use in association with a sink unit having a basin carried by a top element. The nozzle fixture includes a housing having a nozzle, and a base with an aperture formed therethrough. An anchor post extends downwardly from the base and is aligned with the aperture. The anchor post defines an air passage therethrough coupled in communication with the aperture formed through the base. A fastener engages the anchor post for securing the nozzle fixture to the top element adjacent the basin. A channel element is carried by the base and defines a channel coupling the aperture to the nozzle. The fastener can also include a bracket captured on the anchor post between a nut threaded onto the anchor post and the housing.
The nozzle fixture can also include a sensor switch carried by the base for activating a pressurized air source to supply pressurized air to the nozzle through the anchor post. The sensor switch is activated by detecting an object in a predetermine drying region.
In another aspect of the present invention, provided is a sink unit with hand drying assembly including a casement having a top element, a front and a back. A basin having a rim is carried by the casement with the rim adjacent the top element. A faucet is carried by the casement intermediate the basin and the back. A nozzle fixture is carried by the top proximate the rim of the basin toward the front of the casement. The nozzle fixture includes a housing having a nozzle, and a base with an aperture formed therethrough. An anchor post extends downwardly from the base to a position below the top element. The anchor post defines an air passage therethrough, the air passage aligned with and coupled in communication with the aperture formed through the base. A fastener engages the anchor post and secures the nozzle fixture to the top element adjacent the basin. A channel element is carried by the base and defines a channel coupling the aperture to the nozzle. An air conduit couples a pressurized air source to the anchor post.
The foregoing and further and more specific objects and advantages of the invention will become readily apparent to those skilled in the art from the following detailed description of a preferred embodiment thereof, taken in conjunction with the drawings in which:

In this embodiment, basin 14 is carried by top element 22 of casement 12 intermediate front edge 23 and back edge 24. Faucet 16 is carried by top element 22 (which can be part of sink basin 14) intermediate sink basin 14 and back edge 24. It will be understood that for purposes of orientation the terms “front” and “back” are used to designate the position relative a user 25, depicted in broken lines. The “front” designates the side of the casement user 25 stands at for use, and the term “back” is the side opposite the user, where faucet 16 is positioned. Depending on the basin type employed, top element 22 can underlie or be integrally formed with a rim 28 of sink basin 14. In the embodiment illustrated, basin 14 includes rim 28 underlying top element 22. The placement of sink basin 14 within casement 12 is variable, and can be adjusted to the depth of substantially any vanity casement as with any conventional basin.

Hand drying assembly 20 further includes couplers 70 coupling a pressurized air conduit 72 to anchor posts 40, supplying pressurized air (or other gasses) through air passage 44 to nozzles 50 of nozzle fixture 30. In the preferred embodiment, while couplers 70 are quick release couplers allowing for ease of installation, other couplers requiring more labor intensive attachment such as solder, threads, adhesive and the like, can be employed. Referring specifically to
With attention directed to
It should be noted that the air stream provided by this invention for drying hands, has a low volume but a very high velocity. High velocity and low volume are achieved through the use of compressed air, regulated by a regulator to provide the desired volume and velocity. By employing high velocity low volume air, and adjusting the direction thereof, optimum air velocity and volume are achieved at drying region W. Since the air volume is low, outside area W, the air dissipates and quickly disappears. This prevents air movements from causing issues outside area W. Conventional air dryers employ high volume, low velocity air. This is opposite to the resent invention. This air will not dissipate quickly due to the large volume, and can cause issues outside of the drying area.

Basin 114 is carried by top element 122 of casement 112 intermediate front edge 123 and back edge 124. It will be understood that for purposes of orientation the terms “front” and “back” are used to designate the position relative a user as in the description of sink unit 10. The “front” designates the side of the casement a user stands at for use, and the term “back” is the side opposite the user. Depending on the basin type employed, top element 122 can underlie or be integrally formed with a rim 125 of sink basin 14. In the embodiment illustrated, basin 114 includes rim 125 underlying top element 122. The placement of sink basin 114 within casement 112 is variable, and can be adjusted to the depth of substantially any vanity casement as with any conventional basin.

As an example, nozzle fixtures can be mounted between sink basins in public facilities, or on completely separate vanities. Various changes and modifications to the embodiments herein chosen for purposes of illustration will readily occur to those skilled in the art. To the extent that such modifications and variations do not depart from the spirit of the invention, they are intended to be included within the scope thereof, which is assessed only by a fair interpretation of the following claims.
