  • the specific structure may be described in detail below.
  • the volute fan combination structure comprises a mounting plate 4, as well as three volute fans (hereinafter referred to as fans for short).
  • the three volute fans comprise a first volute fan 1 provided at an upper side of the mounting plate 4, a third volute fan 3 located a lower side of the mounting plate 4, as well as a second volute fan 2 provided on the mounting plate 4 and located between the first volute fan 1 and the third volute fan 3.

  • the mounting plate in the present embodiment is provided in a longitudinal direction, and the three volute fans are also arranged in a longitudinal direction, the technical solution of the present application should not be limited in a mounting plate structure provided in a longitudinal direction. It is both possible that the mounting plate uses a horizontal arrangement or an inclined arrangement.
  • the longitudinal, latitudinal and front-and-rear definitions mentioned in the present text are all relative directions with respect to the mounting plate.
  • the second volute fan 2 is disposed between the first volute fan 1 and the third volute fan 3, and the air outlet is provided in such a manner as to blow air longitudinally. If three fans are mounted on the same plane according to a conventional manner, the volute of the first volute fan 1 and the volute of the third volute fan 3 may form a barrier for the air blowing of the second volute fan, which impedes air blown by the second volute fan 2 from smoothly entering the main body air duct 56. Accordingly, the three fans are provided to present a staggered structure in space, such that the second volute fan first air outlet 28 and the second volute fan second air outlet 29 are staggered in space from positions of the first volute fan 1 and the third volute fan 3.
  • the influence on the air blowing of the second volute fan 2 by the first volute fan 1 and the third volute fan 3 is reduced to minimum as much as possible, for example the three fans are staggeringly disposed in a front-and-rear direction and/or a latitudinal direction.

  • a mounting position of the second volute fan 2 on the mounting plate 4 is disposed at a front side of mounting positions of the second and third volute fans by changing a shape of the mounting plate 4.
  • the mounting plate has a first fan mounting portion 41, a second fan mounting portion 42 and a third fan mounting portion 43, in which steps are formed between the second fan mounting portion 42 and the first fan mounting portion 41/third fan mounting portion 43, such that the second fan mounting portion 42 projects in a forward direction towards the front panel 51 relative to the first fan mounting portion 41 and the third fan mounting portion 43.
  • a mounting position of the second volute fan 2 on the mounting plate 4 is located at a front side of mounting positions of the first and third volute fans when the three fans are mounted on the mounting plate 4.
  • the advantage of staggered arrangement back and forth is only to increase a thickness in a front-and-rear direction for certain extent, without increasing a thickness of the volute fan assembly in a latitudinal direction, so that there is a very slight influence on the overall size of the air conditioning device.
  • the rear walls of the second volute fan first air outlet 28 and the second volute fan second air outlet 29 have an inner surface which may present a plane parallel to the mounting plate, and the extension of the plane does not intersect with the volutes of the first volute fan 1 and the third volute fan 3 respectively. In this way, it may allow that the air blown by the second volute fan 2 may not be blown onto the volutes of the first volute fan 1 and the third volute fan 3, and the influence on the air blowing of the second volute fan 2 by the first volute fan 1 and the third volute fan 3 is reduced to minimum.
  • the three fans are staggered in a latitudinal direction (not shown in the drawings), i.e. the second volute fan 2 is arranged at a left side or a right side of the first volute fan 1 and the third volute fan 3, which may also effectuate reducing disturbance of the air blowing of the second volute fan by the first volute fan 1 and the third volute fan 3.
  • such manner may significantly increase a width of the volute fan assembly in a latitudinal direction, which is unfavorable for the overall layout of the air conditioning device.
  • the second volute fan first air outlet 28 and the second volute fan second air outlet 29 of the second volute fan 2 may also be inclinedly disposed relative to the volute of the second volute fan 2.
  • the volute of the second volute fan 2 is mounted in such a manner as to be substantially parallel to a plane of the second volute fan mounting portion 42 of the mounting plate 4.

  • the third inclination ⁇ 3 may be the same as or different from the fourth inclination ⁇ 4 in size.
  • the extension of the slope or the extension 2821 of the tangent of the camber of the inner surface 282 of the rear wall of the second volute fan first air outlet does not intersect with the volute of the first volute fan 1, as shown in Figure 4 .

  • An extension of the slope or an extension 2921 of the tangent of the camber of the inner surface 292 of the rear wall of the second volute fan second air outlet does not intersect with the volute of the third volute fan 3.
  • Such combination of staggered manners may reduce an increase in a thickness (a front-and-rear direction) of the volute fan combination structure resulting from staggering in a front-and-rear direction, and at the same time may also avoid that the inclined angles of the second volute fan first air outlet 28 and the second volute fan second air outlet 29 relative to the volute is so large as to affect the air blowing of the volute fan, ensure that there is no significant increase of size in both a thickness (a front-and-rear direction) and width (a latitudinal direction) of the volute fan combination structure, and facilitate an optimized design of the overall structure of the air conditioning device.
