Definitions

  • the present invention relates to an apparatus to deliver hot air, of the type comprising a protection casing to be fixed to a wall, an air delivery unit electrically operated and housed in the protection casing and at least a pushbutton to actuate the delivery unit.
  • the apparatus in question is particularly adapted to be used as hair or hand drier in public and private use utility premises, such as dressing rooms and showers in gymnasiums, swimming pools and the like, bathrooms in hotels, restaurants, private houses and so on.
  • these apparatuses substantially comprise a protection casing to be fixed to a wall, in which a hot air delivery unit is housed.
  • This delivery unit conventionally comprises a tubular or spiral-shaped structure to the opposite ends of which an air inlet and an air outlet are defined which are in communication with the surrounding atmosphere. Housed in the tubular or spiral-shaped structure in consecutive alignment starting from the air inlet, are an impeller, an electric motor to operate the impeller and one or more resistors.
  • the delivery unit can be electrically actuated by at least a timed switch exposed on the casing surface to be hand-actuated by a user.
  • Several apparatus to be used as hair driers are actuated by a lever to which a flexible hose is hung which is connected, at one end thereof, to the outlet of the delivery unit.
  • the apparatus is activated by the disengagement of the hose from the lever and can only be deactivated when the hose is hung back.
  • the main object of the present invention is to solve the problems of the known art by providing an apparatus to deliver hot air in which all electrical components are properly protected both from humidity and possible water splashes which may reach the protection casing, so as to ensure a complete safety of use as regards the possibility of short-circuits in operation and the possibility of transmitting electric shocks to the user while he is activating or deactivating the apparatus.
  • said protection casing comprises said base wall having a substantially rectangular shape with a rounded upper end, a dome-shaped portion extending from said rounded upper end in a downwardly inclined fashion with respect to said base wall, and two side portions laterally extending in the same inclined direction from said dome-shaped portion, each side portion (9) being connected to a corresponding side edge of said base wall with the width of each side portion gradually decreasing away from said dome-shaped portion towards said corresponding side edge, an opened passage of said protection casing being defined by the external perimeter of said portion and said two side portions on opposite side with respect to said base wall; said air delivery unit is oscillatably pivoted to said protection casing by two pivots each of which being hinged to one of said two side portions, said air delivery unit being movable from a non-use position in which it is substantially parallel to said base wall, to a use position in which it is inclined away from said base wall;
  • the inventive apparatus is structured so as to perfectly protect all electrical components provided therein against possible water splashes or humidity.
  • both the operating pushbutton and air inlet of the delivery unit are protected by said casing and practically cannot be reached by possible water splashes that might fall onto the casing.
  • 1 generally denotes an apparatus to deliver hot air according to the invention.
  • apparatus 1 in known manner substantially comprises a protection casing 2 to be fixed to a wall referenced by 3, a hot air delivery unit 4 housed within casing 2 and at least a pushbutton 5 to operate the delivery unit 4.
  • the protection casing 2 preferably made of an electrically insulating plastic arterial, comprises a base wall 6 designed to allow the fastening of apparatus 1 to a wall 3 by means of nogs 7 or the like.
  • said fastening can also be carried out using a pressure sensitive double-adhesive tape.
  • the base wall 6 has a substantially rectangular configuration with a rounded upper end from which a dome-shaped portion 8 extends in a downwardly inclined fashion.
  • each side portion 9 Laterally extending in the same inclined direction from the dome-shaped portion 8 are two side portions 9 which prolong their length parallelly downwardly and are connected each to a corresponding side edge of the base wall 6; the width of each side portion 9 is gradually decreasing away from said dome-shaped portion, towards said corresponding side edge, as clearly shown in Fig. 2.
  • the delivery unit 4 comprises a tubular structure 10 at the opposite ends of which an air inlet and an air outlet identified by reference numerals 10a and 10b respectively, are defined. Housed in the tubular structure 10, in consecutive alignment starting from the air inlet 10a, are an impeller operated by an electric motor and one or more resistors acting close to the air outlet 10b. All components enclosed in the tubular structure 10 are not shown or further described as known per se and conventional.
  • the delivery unit 4 is disposed vertically and its air inlet 10a is directed upwardly and is exposed on casing 2 through an open side thereof defined by the external perimeter of said portion 8 on the opposite side with respect to the base wall 6.
  • the delivery unit 4 is oscillatably connected to casing 2 according to a substantially horizontal axis, by means of two pivots 11 rotatably engaging into the side portions 9 of the casing.
  • the delivery unit 4 is engaged to the protection casing 2 so as to be movable from a non-use position in which, as shown in solid line in Fig. 2, it is oriented substantially upright, to a use position in which, as diagrammatically shown in dotted line in Fig, 2, it has a slanting orientation away from wall 3.
  • Stop means can be advantageously provided to fix the positioning of the delivery unit 4 in its use condition.
  • said stop means consists of a peg 12 made of elastically deformable material fastened to the dome-shaped portion 8 of casing 2 and designed to be elastically engaged by the tubular structure of the delivery unit 4 when the latter is brought to its use position. Under this condition the engagement of peg 12 on the surface of tubular portion 10 brings about a stable positioning of the delivery unit 4 in its use condition.
  • Peg 12 can be replaced by one or more magnets performing the same function, which are fastened to the casing and act on metal elements secured to the tubular structure 10.
  • the operating pushbutton 5 is advantageously located at the inside of the protection casing 2 so as to be actuated by the delivery unit 4 as a result of the latter moving to its use position.
  • pushbutton 5 is secured to the upper part of the base wall 6, immediately under the dome-shaped portion 8 suitably protecting it against possible water splashes and the like and is provided with a drive arm 13 designed to interfere with the movement of the delivery unit 4 to close the pushbutton contacts when the delivery unit is brought to its use position.
  • the impeller therein provided causes the drawing in of air through the air inlet 10a.
  • the drawn-in air is taken from the surrounding atmosphere through the hollow spaces existing between the delivery unit 4 and protection casing 2, as well as, optionally, through slits suitably formed in the side portions 9 of said casing.
  • the air drawn in through the air inlet 10a is heated at the inside of the tubular structure 10 and delivered through the air outlet 10b.
  • a flexible hose 14 should preferably be combined therewith; said flexible hose 14 partially shown in dotted line, extends from the air outlet 10b and the free end thereof, not shown, can be equipped with several different accessories, such as diffusers, brushes and the like and conventionally fastened to casing 2 by suitable hooking means not shown. In this case it will be sufficient to direct said free end of the flexible hose 14 towards the user's head to cause said hose to move apart from wall 3, which brings about the orientation of the delivery unit 4 into its use position and, as a result, the activation of the same upon the action of pushbutton 5.
  • hose 14 When hose 14 is merely released the use of apparatus 1 being no longer necessary, it comes automatically close to wall 3; in fact the weight of said hose overcomes the resistance offered by peg 12 and automatically brings back the delivery unit 4 to its non-use position, causing the deactivation thereof.
  • the present invention attains the intended purposes.
  • the inventive apparatus is in fact structured so as to perfectly protect all electrical components provided therein against possible water splashes or humidity. It is to be pointed out in this connection that both the operating pushbutton 5 and air inlet 10a of the delivery unit 4 are protected by casing 2 and practically cannot be reached by possible water splashes that might fall onto the casing.
  • activation of pushbutton 5 achieved by the displacement of the delivery unit 4 eliminates the necessity for the user to act directly on said pushbutton to control the apparatus operation.
  • the switching on and off of the apparatus are achieved by directly acting on the tubular structure 10 or flexible hose 14, that is to say on elements made in electrically insulating arterial and located rather far from pushbutton 5.
