Definitions

  • the object of this application is the registration of a hand dryer device.
  • the invention proposes the development of a hand drying device that allows the hands of a user to be introduced from the front portion of the device through a chamber that is superiorly open.
  • hand dryer devices There are basically two main types of hand dryer devices on the market. One of them is the traditional machines (also called “hands under”), in which the user places their hands under the device and, on the other hand, and of more recent temporary expansion, the devices having a drying chamber for the user to introduce the hands from above (also called “hands in”).
  • the user has no contact with the casing of the device and can clearly see the hands.
  • the water falls to the ground and can splash the user.
  • the present invention has been developed with the aim of providing a hand dryer device that is configured as a novelty within the field of application and solves the previously mentioned drawbacks, further contributing other additional advantages that will be obvious from the description below.
  • a hand dryer device comprising a casing defined by a front region, a rear region and two lateral regions, a drying chamber superiorly open formed in the upper portion of the same casing configured for the insertion of the hands of a user, aeration means provided for orienting an air flow rate towards an outlet located in the area of the chamber, and detection means for detecting the presence of the hands of the user in the drying chamber.
  • the invention is characterised in that the drying chamber runs from the front region to the rear region of the casing, the drying chamber being laterally delimited by two arms facing each other, which extend vertically from the corresponding lateral regions, the drying chamber having dimensions for the insertion of both hands together from the front area of the casing (and not only from the upper portion as in currently known hand dryers), in which the air outlet is located on the internal face of the two arms that extend so that the air flow rate is laterally oriented towards the hands of a user.
  • the distance between the two arms is such that the hands of the user can be inserted frontally.
  • the hands of a user can be positioned in the drying area either from top to bottom (vertically), or from outside inwards (horizontally) or in any combination of both without touching the casing of the device during the positioning of the hands and away from the walls of the same device, or during the drying process.
  • the hand dryer device of the present invention allows the user to see their hands while drying them, that the water does not fall to the ground, further preventing it from splashing on the user during the drying operation, and it is high-speed but allows the hands to be farther away from the device and thus prevent contact with the same device, and hands do not have to be introduced inside a closed-looking compartment.
  • the feeling of putting the hands "inside something”, of which the state of cleanliness is unknown, is something that is not usually desired by the user.
  • the hands are not placed “inside anything”, but rather users see where they put their hands, and it would not be a “hands in” but neither would it be a "hands under” of those initially referred to.
  • the aim of this novel arrangement is to combine the positive aspects of the two main known types of hand dryer devices.
  • the device of the invention may include water evacuation means intended for evacuating water from the hands of the user.
  • the water evacuation means comprise a cage or extension located on the rear face of the casing of the device, which has a sunken section having at its bottom at least one drainage outlet linked to a water evacuation conduit.
  • the air outlet is defined by two holes facing each other, each of the holes being in a respective arm.
  • the aforementioned aeration means comprise a body that forms two nozzles that extend from a lower portion that can be coupled to air propulsion means, each of which has a final ending that is inclined with respect to a horizontal plane, such that the outlet flow exiting through the air outlets is oriented downwards, and also in such a way that the air can be projected in the direction of the wall or support surface where the dryer is mounted, minimising water splashes to the ground from the hands of the user.
  • these nozzles have been designed so that they conduct the air so that the air jets hit the hands.
  • the detection means comprise at least one infrared sensor located on the internal face of one of the arms.
  • the device described represents an innovative structure with structural and constituent features heretofore unknown for its intended purpose, reasons which, taken together with its usefulness, provide it with sufficient grounds for obtaining the requested exclusivity privilege.
  • One embodiment of the hand dryer device essentially comprises a casing (1), made for example of an injection mouldable plastic material, which is defined by a front region (11), a rear region (12) and two lateral regions (13), a drying chamber (2) superiorly open that is formed in the upper portion of the casing itself (1) configured for the insertion of the hands of a user, aeration means provided for orienting an air flow rate towards an outlet located in the area of the drying chamber (2), and detection means for detecting the presence of the hands of the user in the drying chamber (2).
  • a casing (1) made for example of an injection mouldable plastic material, which is defined by a front region (11), a rear region (12) and two lateral regions (13), a drying chamber (2) superiorly open that is formed in the upper portion of the casing itself (1) configured for the insertion of the hands of a user, aeration means provided for orienting an air flow rate towards an outlet located in the area of the drying chamber (2), and detection means for detecting the presence of the hands of the user in the drying
  • the same runs transversely from the front region to the rear region of the casing, the drying chamber (2) being laterally delimited by two arms (14) facing each other, and presenting a U-shaped general geometry as can be seen in the figures.
  • the two arms (14) extend vertically from the corresponding lateral regions, the drying chamber having dimensions for the insertion of the two hands from the front area of the casing (1), wherein the air outlet is located on the internal face of the two arms (14) that extend parallel to each other, internally defining a curvature area, in such a way that the air flow rate is laterally oriented towards the hands of a user.
  • the air outlet of the drying device is defined by two outlet holes (3) facing each other, each of the outlet holes (3) being in a respective arm (14).
  • the device includes water evacuation means for removing water coming from the hands of the user.
  • These water evacuation means comprise a cage (4) located on the rear region (12) of the casing (1), which has a sunken section (5) superiorly with a curved-concave shape having at its bottom at least one drainage outlet (6) (a through hole) linked with a water evacuation conduit (not shown).
  • aeration means comprise a body that forms two nozzles (7) that extend from a lower portion (8) that can be coupled to air propulsion means, each of which having a final ending that is inclined with respect to a horizontal and vertical plane, such that the outlet flow exiting through the outlets is projected downwards and slightly towards the rear portion of the casing (1) where the water evacuation means are located, as shown represented by means of arrows in figure 6 .
  • the orientation of the air outlet can also be towards a wall area on which the drying device is mounted in order to minimise water splashes.
  • the aeration means may include a thermal resistor that provides a heated air flow.
  • the detection means comprise a pair of infrared sensors (9) located on the internal face of each of the arms (14) or extensions of the lateral regions (13), so that when they detect the presence of hands on the area of the drying chamber, the aeration means are automatically activated. It should be mentioned that the sensors (9), together with the aeration means, are linked to each other through a control unit that governs the operation of the dryer device.
  • the distance (d) between the two arms is such that the hands of the user can be inserted frontally side by side, as represented with the arrows (f).
  • the sensors (9) detect their presence and activate an electric motor that drives a fan.
  • an air flow rate captured by an air intake (10) is introduced at a previously determined speed in the equipment that makes up the aeration means, so that it passes through the inside of the two nozzles (7) in the direction of the outlet holes (3).
