Definitions

  • the present invention relates to a ventilation device equipped with a valve for opening and closing an aperture for the passage of an airflow.
  • Ventilation devices for buildings are normally equipped with a first fan unit that generates a first airflow directed from the inside outwards and a second fan unit that generates a second airflow directed from the outside inwards.
  • the two airflows are usually arranged in a relationship of mutual heat exchange within a heat exchanger, for the recovery of the thermal energy of the airflow directed outwards.
  • Air exchange devices of this type can be equipped with valve devices to close one or both of the apertures communicating with the outside of the building.
  • the valve devices may envisage the use of movable partitions for the opening and closing of the apertures in communication with the external environment
  • the present invention aims to provide a ventilation device with a valve for opening and closing an aperture for the passage of an airflow, having a smaller footprint.
  • this object is achieved by a device having the features forming the subject of claim 1 .
  • FIG. 1 is an exploded perspective view of a ventilation device according to the present invention
  • FIG. 2 is a perspective view of a valve device indicated by the arrow II in FIG. 1 ;
  • FIGS. 3 and 4 are perspective views illustrating the valve device of FIG. 2 in a partially closed and fully closed condition, respectively;
  • FIG. 5 is a cross-section of the valve element indicated by the arrow V in FIG. 2 ;
  • FIG. 6 is an exploded cross-section of the valve element of FIG. 5 .
  • numeral 1 indicates an air exchange device for buildings according to the present invention.
  • the device 1 comprises a casing including a base 2 and a lid 3 , which can be made of rigid injection-molded plastic material.
  • the device 1 is intended to be mounted in an internal environment of a building in order to carry out air exchange with recovery of the airflow energy delivered to the outside.
  • the device 1 is intended to be fixed on a perimetrical wall and communicates with the external environment by means of a pair of holes formed in the perimetrical wall.
  • the base 2 comprises an internal inlet opening 4 , an internal outlet opening 5 , an external inlet opening 6 and an external outlet opening 7 .
  • the external inlet opening 6 and the external outlet opening 7 communicate with the holes formed in the perimetrical wall.
  • the external inlet opening 6 and the external outlet opening 7 are associated with a valve device 8 configured to hermetically close the openings 6 , 7 .
  • the base 2 contains a heat exchanger 11 having a first inlet 12 in communication with the internal inlet opening 4 , a first outlet 13 in communication with the internal outlet opening 5 , a second inlet 14 in communication with the external inlet opening 6 and a second outlet 15 in communication with the external outlet opening 7 .
  • the air exchange device 1 comprises a first fan unit 16 that generates a first airflow F 1 directed from the internal inlet opening 4 towards the external outlet opening 7 and a second fan unit 17 that generates a second airflow F 2 directed from the external inlet opening 6 towards the internal outlet opening 5 .
  • the first and second airflows F 1 , F 2 are in a relationship of mutual heat exchange in the heat exchanger 11 .
  • the outwardly directed airflow F 1 transfers heat to the inwardly directed airflow F 2 .
  • the outwardly directed airflow F 1 cools the inwardly directed airflow F 2 .
  • the first and the second fan units 16 , 17 are housed in an elastic support 18 in the form of cushion, equipped with seats for housing the fan units 16 , 17 and ducts for the passage of the airflows F 1 and F 2 .
  • the valve device 10 comprises a plate 9 , for example of sheet metal, fixed to a bottom wall 10 of the base 2 ( FIG. 1 ).
  • the plate 9 has two openings 6 , 7 for the passage of the airflows F 1 and F 2 .
  • a respective valve element 19 is associated with each opening 6 , 7 .
  • each valve element 19 comprises a fixed crown gear 21 , a rotatable crown gear 20 and a flexible sleeve 22 .
  • the fixed crown gear 21 and the rotatable crown gear 20 have respective openings 24 , 26 aligned with each other and arranged alongside the respective openings 6 , 7 of the plate 9 .
  • the fixed crown gear 21 is fastened to a support 28 ( FIGS. 2-4 ) in turn fastened to the plate 9 .
  • the fixed crown gear 21 and the rotatable crown gear 20 are connected together by means of a threaded coupling 30 , in such a way so that following the rotation of the rotatable crown gear 20 about the axis A, a relative axial displacement between the gears 21 , 20 is also obtained.
  • the flexible sleeve 22 is constituted of a thin tubular-shaped film of flexible and elastic material, such as latex or the like.
  • the sleeve 22 has two opposite ends, which are attached, respectively, to the fixed crown gear 21 and the rotatable crown gear 20 .
  • the opposite ends of the flexible sleeve 22 are fixed to two o-rings 32 , 34 that are inserted within the respective grooves 36 , 38 formed in the fixed crown gear 21 and the rotatable crown gear 20 .
  • each valve device 19 comprises an actuator 40 for controlling the rotation of the respective rotatable crown gear 20 about the axis A.
  • the actuator 40 is an electric motor, which rotationally drives a worm screw 42 that engages with a helical gear 44 of the rotatable crown gear 20 .
  • Position sensors associated with the rotatable crown gear 20 may also be provided and configured to stop the actuator 40 when the rotatable crown gear 20 reaches the open position and the closed position.
  • the flexible sleeve 22 In the open position, illustrated in FIGS. 2 and 5 , the flexible sleeve 22 has an annular shape and is adjacent to the edges of the openings 24 , 26 . In this condition the opening 6 , 7 is open and allows the transit of an airflow.
  • the rotatable crown gear 20 is rotationally driven about the axis A by means of the actuator 40 .
  • the two opposite ends of the flexible sleeve 22 rotate relative to one another.
  • the flexible sleeve 22 consequently assumes a diaphragm shape as shown in FIGS. 3 and 4 .
  • FIG. 3 illustrates a partially closed position
  • FIG. 4 illustrates the fully closed position of the valve device 19 .
  • the worm screw and helical gear transmission system is unidirectional so that the rotatable crown gear 20 is retained in a stable manner in the position that is reached. This also partially closed stable positions of the valve device 19 .
  • the valve device 19 according to the present invention can be used in air exchange devices for buildings and in any other application where there is the need to completely or partially close a duct for the passage of an airflow.
