Definitions

  • the present invention refers to the aeraulic field, in particular to implants and systems for air treatment of industrial and civil environments.
  • the present invention refers, more in detail, to a model of an electric recirculating air fan heater, designed to air heating of civil and industrial environments in order to disinfest and sanitize.
  • US6466737 discloses a conditioning system comprising two independently operating separable units
  • WO 01/40714 discloses a stove, provided with two rotationally connected units, that allows adjustability for the hot air flow output.
  • Aim of the present invention is to allow environmental disinfestation and sanitation activities that mainly develop vertically (for example silos), by introducing hot air generated by an electric fan heater whose shape can be mutated in order to facilitate both the transport and the use of the whole hot air generator.
  • the electric fan heater of the present invention is preferably provided with hinges and releasing and locking means which allow to vary shape and size of the electric fan heater, switching from a transport configuration to a use one and vice versa.
  • the electric fan heater according to the present invention comprises a medium pressure centrifugal fan which intakes air from the environment to be treated, canalizes it into a duct where, after passing through a set of electrical resistors, is heated and released into the vertical structures, allowing the heating of the entire volume in which it is placed.
  • the electric fan heater A is an assembly - or device - comprising a first and a second box-shaped body, respectively denoted by the reference 1 and 2, which, in the illustrated example, are connected to each other by means of hinges 24 and a fast releasing means 6.
  • the box-shaped body 1 comprises:
  • FIG. 1 shows inside the upper compartment 1 there are preferably lifting and opening equipment for the opening 4 useful to facilitate lifting the box-shaped body 2, when the electric fan heater A, from a transport configuration ( Figure 2 ), requires to be placed in an operating configuration ( Figure 1 ).
  • a fixed support 29 of the fast releasing means 6 is anchored to the perimetral edge of the box-shaped body 1, as illustrated in figure 1 ; in the fixed support 29, hinges 24 preferably mounted on the perimetral edge of the box-shaped body 2 are preferably inserted, again with reference to Figure 1 .
  • the device in accordance with the present invention comprises coupling means 24, 6 configured to connect the first and second box-shaped bodies 1, 2 along a respective perimetral edge.
  • the wheels 16 for handling the electric fan heater A are the wheels 16 for handling the electric fan heater A; said wheels 16 can also be replaced by fixed elements, without thereby not being considered in the scope of the present invention.
  • the electric panel 3 preferably contains all control and safety devices of the electric fan heater A.
  • an electronic control unit 17 to control the entire electric fan heater system A is present in the frontal part of the electric panel 3.
  • the box-shaped body 2 comprises:
  • the fixed elements 20 for the placement on the ground are present.
  • the handles 21 and the locking means 22 and 23 are present, which said locking means 22, denoted with reference 22, blocks the second box-shaped body 2 to the first box-shaped body 1 when electric fan heater A is in operating configuration as showed in figure 1 ; the locking means 23 blocks, instead, the second box-shaped body 2 with the first box-shaped body 1 when electric fan heater A is in transport configuration as showed in figure 2 .
  • the exhaust ducts 8 and suction ducts 9 are for the intake of hot air.
  • Each of said ducts 8, 9 connects the flexible pipes having the function of exhausting (duct 8) and sucking (duct 9) hot air into the environment to be treated.
  • said exhaust duct 8 and suction duct 9 of the second box-shaped body 2 open on opposite sides of the latter with respective suction and exhaust openings.
  • the hinges 24 are fixed as showed in figure 1 ; the hinges 24 fit in the fixed support 29 of the releasing means 6.
  • the hinges 24 are anchored to the fixed support 29 through the pins 28 of the releasing means 6, so as to constrain the first and the second box-shaped bodies 1, 2 each other.
  • the fast releasing means 6 of the preferred embodiment from figure 3 comprises the fixed support 29, the pins 28, levers 27, the driving element 26 and the key 25.
  • the key 25 fits in the driving element 26 which is coupled to the fixed support 29 though the screw 30.
  • the levers 27 are hooked, which levers 27 are coupled to respective opposite ends of the pins 28.
  • the levers 27 retract extracting the pins 28 from the hinges 24 and from the fixed support 29, thus placing the fast releasing means 6 in the release mode; in this way, the second box-shaped body 2 is released from the first box-shaped body 1, thus allowing their detachment.
  • driving element 26 is aligned with the levers 27, the pins 28 are inserted in the hinges 24 and in the fixed support 29; the fast releasing means 6 is thereby in a hooking position and the first and the second box-shaped bodies 1, 2 of the electric fan heater A are bounded together.
  • the hinges 24 and the fast releasing means 6 allows the second box-shaped body 2 to be rotated of 180° with respect to the first box-shaped body 1, thus positioning the electric fan heater A from the transport configuration ( figure 2 ) to the operating configuration ( figure 1 ) and vice versa.
  • the configuration of the coupling means 24, 6 is such as to allow a reversible overturning of the second box-shaped body 2 from a transport configuration of the fan heater A wherein the second box-shaped body 2 rests on the first box-shaped body 1, to an operating configuration wherein their respective air exhaust ducts 11, 8 and suction ducts 12, 9 are in fluid communication through said corresponding openings.
  • the lifting box-shaped body 2 is favoured by lifting means 4 used for opening, which said means 4 is placed inside the upper compartment of the first box-shaped body 1.
  • the second box-shaped body 2 is secured to the first box-shaped body 1 through the locking means 22; in this configuration, the cam 19 presses the safety contacts 13 present on the first box-shaped body 1, thus allowing the electric fan heater A to operate in total safety.
