Definitions

  • the present invention is generally directed to a dryer with an integrated splash guard, as well as splash guards for existing hand dryers that eliminates or reduces water from being splashed from the hands during the drying process onto the nearby walls, floor and clothes of the user.
  • Wall or surface mounted dryers have been used for many years in washrooms for drying a person's hands. Originally, most of these dryers used a low velocity air, causing the drying process of the hands to be fairly slow. To speed up the drying process, many manufacturers created high speed or high velocity hand dryers. As the velocity of the air impacting the hands increases, the water or moisture on the hands is increasingly sprayed off in a fine mist to the surrounding surfaces, particularly depending on how the user positions their hands. In certain high usage situations, such as airports and sporting facilities, the water and moisture may visibly accumulate on the walls, floor and surrounding surfaces. To protect the surrounding surfaces, manufacturers have tried a number of options, none of them completely successful.
  • the ADA requires that protruding objects with leading edges more 27 inches (685 mm) and not more than 80 inches (2030 mm) above the finished floor or ground shall not protrude more than 4 inches (100 mm) maximum horizontally into a circulation pathway, such as a hallway or passageway.
  • Many facilities have substantial design limitations where the hand dryer may actually be installed, including when considering the flow of people entering and exiting a washroom.
  • all traditional hand dryers mounted to a wall must be mounted much higher than 27" from the ground to be functional, leaving only two options to meet ADA requirements, recess the dryer into the wall so that it protrudes less than 4", or use a low profile dryer having a complete thickness when mounted of less than 4".
  • Low profile hand dryers are expensive when compared to tradition hand dryers and are not capable of providing high speed air drying. Furthermore, low profile hand dryers are difficult to use, as the user typically needs to place their hands extremely close to the supporting surface to insert them into the air stream. Given the positioning of the hands, the user typically contacts the wall at least once during the drying process. In addition, the close proximity to the wall only amplifies the water and moisture problems discussed above.
