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, saunas and/or premises where sports are generally practised, as well as in bathrooms in hotels, restaurants and the like. It is known that in premises of the above type there often is the installation of apparatuses designed to produce a hot air flow so that a user may dry his hair or hands quickly and hygienically.
  • Apparatuses of this kind substantially comprise a protection casing to be fixed to a wall and a hot air delivery unit accommodated within the protection casing.
  • Housed in the delivery unit is an electric motor operable by means of a pushbutton projecting outwardly from the protection casing, and operated by the electric motor is an impeller drawing air in through an inlet formed in the delivery unit and sending it to one or more resistors disposed close to an outlet formed on the opposite side to the inlet. The air sent to the resistors is then heated and delivered to the surrounding atmosphere through said outlet.
  • the main object of the present invention is to solve the drawbacks of the known art by providing an apparatus exhibiting construction contrivances adapted to prevent the water which may be accidentally dropped onto the protection casing from reaching the electric components of the apparatus, while protecting at the same time the user against the possibility of electric shocks when he operates the pushbutton.
  • an apparatus to deliver hot air characterized in that the delivery unit is slidably engaged with the protection casing and in that said pushbutton acts between said protection casing and the delivery unit to cause the operation of said delivery unit when the latter moves within the casing from a non-use position to an operating position, positioning means being provided to selectively retain the delivery unit in its non-use position and operating position.
  • 1 globally denotes an apparatus to deliver hot air in accordance with the present invention.
  • Apparatus 1 comprises a protection casing 2 to be fastened to a wall 3 and accommodating a hot air delivery unit 4 operable by means of a pushbutton 5.
  • the protection casing 2 made of an electrically insulating material, has a base portion 6 fixable to wall 3 by means of expansion nogs 7 or the like. Extending forward from the top of the base portion 6 is an upper portion 8 to which a downwardly extending front portion 8a is connected. Two side portions 9 extend from the opposite sides of the upper 8, front 8a and base 6 portions, an opening 2a being formed between the above mentioned portions, at the lower part thereof.
  • flaps 10 are housed at the inside of the protection casing 2; they are integral to the base portion 6 and have each a through slot 11 disposed in a substantially vertical direction.
  • the delivery unit 4 is comprised of a housing 12, made of plastic material, at the opposite ends of which an air inlet 12a and an air outlet 12b are respectively defined. Located inside the housing 12 is an electric motor connected to an impeller disposed close to the air inlet 12a and one or more resistors housed in the vicinity of the air outlet 12b.
  • the housing 12 is provided on its outer opposite sides, with two projections 13 each guided within the slot 11 of one of the two flaps mentioned above.
  • the delivery unit 4 is oriented in a vertical direction the air inlet 12a being disposed upwardly, and is in communication with the surrounding atmosphere through the opening 2a provided at the lower part of the protection casing 2.
  • the pushbutton 5 to operate the delivery unit 4 is disposed within the protection casing 2 so as to be acted upon by the delivery unit itself when the latter moves, while slightly rising, from a non-use position to an operating position.
  • the housing 12 is provided with a drive lug, referenced by 14 in Fig. 1, located to such a position as to cooperate with the pushbutton 5 to close the contacts thereof when the delivery unit 4 moves to its operating position.
  • apparatus 1 is also provided with positioning means to selectively retain the delivery unit 4 in its non-use position and operating position.
  • said positioning means consists of the combination of at least a return spring and a flexible hose 15 shown in dotted line, the weight of the latter being higher than the lifting force of the return spring.
  • the return spring may for example be a helical spring 16 one end of which is engaged with the upper portion 8 of the protection casing 2, the opposite end being engaged with the housing 12 of the delivery unit 4.
  • an elastic bearing identified by 17 in Fig. 1, supported by a fastening portion 17a integral to the base portion 6 of the protection casing 2.
  • the elastic bearing 17 incorporates a seat 17b inside which a projecting portion 4a of the delivery unit 4 engages.
  • the elastic bearing 17 is made of rubber or another elastomeric material.
  • the non-use position of the delivery unit 4 is held as far as the weight of the flexible hose 15 connected to the delivery unit 4 has a higher value than the lifting force of the helical spring 16 and/or elastic bearing 17 and/or magnet 18. In this position the drive lug 14 provided on housing 12 does not come in contact with the pushbutton 5.
  • the apparatus of the invention can also be arranged so as to be used as a hand drier.
  • the flexible hose 15 is not necessary and the positioning means essentially comprises a bistable spring, referenced by 20 in Fig. 2, one end of which is engaged in a seat 20a incorporated in the base portion 6, the other end being engaged in a further seat 20b incorporated in the housing 12.
  • the bistable spring 20 retains the delivery unit 4 in its non-use and operating positions respectively.
  • the displacement of the delivery unit 4 from the operating position to the non-use position and vice versa is achieved by a mere manual action directly carried out on the housing 12.
  • the present invention attains the intended purposes.
  • the delivery unit 4, pushbutton 5 and all electric components present in apparatus 1 are protected against possible water splashings and/or jets which may accidentally fall and impinge on the apparatus itself.
