  • the balancer portion 60 is disposed so as to have asymmetry.
  • the balancer portion of the cross-flow fan 10 When the balancer portion of the cross-flow fan 10 is molded integrally with the main body portion (the ring portion 61, the connection portions 62, and the auxiliary connection portions 63) of the auxiliary ring, assembly man-hours pertaining to the balancer portion can be saved. Because of that, the cross-flow fan 10 in which rotational wobble is suppressed by the balancer portion can be inexpensively provided.
  • the balancer portion of the fan block 30 When the balancer portion of the fan block 30 is molded integrally with the main body portion (the ring portion 61, the connection portions 62, and the auxiliary connection portions 63) of the auxiliary ring, assembly man-hours pertaining to the balancer portion can be saved. Furthermore, by disposing the balancer portion on the auxiliary ring 60 located on the outer radial portion, the balancer portion resin amount can be reduced and costs can be reduced. Conventionally, the balancer portion has been disposed on the circular annular support plate or the inner peripheral side thereof in order to correct an imbalance of the fan block caused by disposing the blades at an uneven pitch, but when the balancer portion is disposed on the auxiliary ring 60 located more on the outer radial side, the resin amount can be reduced and costs can be reduced.
  • the auxiliary ring 60 in the substantially central portion of the blades 40 to correct imbalance. Because of that, the cross-flow fan 10 in which rotational wobble is suppressed by the balancer portion can be inexpensively provided.
  • the balancer portion can, for example, as shown in FIG. 12 , be disposed as a raised portion 64 on the inner peripheral side of the main body portion, such as on the inner peripheral surface 60d of the auxiliary ring 60.
  • a substantially linear section 64a indicated by the long dashed double-short dashed line is the shape in a case where a balancer portion is not disposed. In this way, when the balancer portion is disposed on the inner peripheral side of the main body portion, rotational wobble can be reduced while suppressing a drop in performance pertaining to blowing caused by disposing the balancer portion.
  • the balancer portion may also be a raised portion disposed in the thickness direction of the main body portion.
  • a raised portion 65 of the auxiliary ring 60 formed by increasing the thickness of one of the plural connection portions 62 or the plural auxiliary connection portions 63 can also be disposed as the balancer portion.
  • a raised portion 66 of the auxiliary ring 60 formed by increasing part of the thickness of the ring portion 61 can also be disposed as the balancer portion.
  • the balancer portion of the cross-flow fan 10 is disposed in the thickness direction of the main body portion, the balancer portion can be disposed in such a way that air resistance does not increase, and rotational wobble can be reduced while suppressing a drop in performance pertaining to the blowing of the cross-flow fan caused by disposing the balancer portion.
  • the ring portion 61 of the auxiliary ring 60 is positioned on the lengthwise direction intermediate section of the plural blades 40 and is combined with the outer ends 40a of the plural blades 40. Because the auxiliary ring 60 is combined with the outer ends 40a of the plural blades 40, flow path loss is suppressed compared to a case where a circular annular plate-like member supports the blades 40 from their outer ends to their inner ends. Furthermore, in the above-described embodiment, the auxiliary ring 60 is located in a position away from the blade base portions 40c on the support plate side of the blades 40 by a distance of 60% of the long dimension from the blade base portions 40c to the blade distal end portions 40d.
  • auxiliary ring 60 is away from the blade base portions 40c by a distance equal to or greater than 55% of the long dimension from the blade base portions 40c to the blade distal end portions 40d, the strength of the cross-flow fan 10 is improved, and this improvement in strength will be described.
  • the blades 40 each have a gently curved plate-like shape, they easily bend in the width direction of the blades 40.
  • stress concentrates in the joint sections between the blade base portions 40c or the blade distal end portions 40d and the support plate 50 or the end plate 21 so that it becomes easier for breakage to occur, or this becomes a factor causing vibration.
  • the plural blades 40 are bundled together by the auxiliary ring 60, it becomes difficult for the blades 40 to bend, so problems such as breakage caused by stress concentration and joint defects caused by bending described above and the occurrence of noise can be eliminated. Furthermore, blade collapse after molding can be suppressed, insertion into fusion slots becomes easy, and blade stiffness on the distal end side from the auxiliary ring can be sufficiently ensured, so workability is further improved.
  • the auxiliary ring 60 is disposed away by a distance equal to or greater than 55% of the long dimension from the blade base portions 40c to the blade distal end portions 40d, in a location offset toward the blade distal end portions 40d from the lengthwise direction exact middle of the blades 40.
  • the auxiliary ring 60 is away by a distance of 60%, but as the blades 40 are bundled together at their lengthwise direction intermediate section, the auxiliary ring 60 is preferably located at a distance equal to or greater than 55% and equal to or less than 75% and even more preferably a distance equal to or greater than 60% and equal to or less than 65%.
  • a configuration which is not according to the invention will be considered where, for example, in order to obtain a block resembling the fan block 30 having the length L1, instead of the auxiliary ring 60, as shown in FIG. 11 , two fan blocks 130 whose blades 140 are relatively short are joined to one another by a support plate 150.
  • the structure of the support plate 150 is the same as that of the support plate 50 described above. Comparing the two conventional fan blocks 130 of FIG. 11 with the one fan block 30 as according to the invention of FIG. 5 , their strength when configuring an impeller is substantially the same, but in the configuration of FIG.
  • the auxiliary ring 60 and the plural blades 40 are formed of resin, and the auxiliary ring 60 is molded integrally with the plural blades 40 by injection molding, for example.
  • injection molding for example.
  • the support plate 50 is also formed of resin, and the fan block 30, in which one support plate 50, one auxiliary ring 60, and plural blades 40 are integrally molded by injection molding, for example, is plurally formed. Additionally, the plural blades 40 are combined by the auxiliary ring 60 that is away from the blade base portions 40c by a distance equal to or greater than 55% of the long dimension from the blade base portions 40c to the blade distal end portions 40d, so it becomes easier to fixedly attach the support plate 50 of one fan block 30 to the plural blades 40 of another fan block. As a result, the blades 40 of each fan block 30 can be lengthened and the number of fan blocks can be reduced so that manufacturing costs can be reduced.
  • the thickness of the ring portion 61 of the auxiliary ring 60 becomes thinner heading from the inner peripheral side toward the outer peripheral side.
  • the thickness t1 on the inner peripheral side is larger than the thickness t2 on the outer peripheral side.
  • the thickness of the auxiliary ring 60 becomes thinner heading toward the outer peripheral side from the connection portions 62 to the ring portion 61. In this case also, blowing characteristics can be further improved.
  • the thickness of the auxiliary ring 60 is thinner on the outer peripheral side than it is on the inner peripheral side, it becomes easier to remove the fan block 30 of the cross-flow fan 10 from the mold during injection molding.
  • the inclination of the auxiliary ring 60 heading from the outer peripheral side toward the inner peripheral side is greater on the first surface 60a on the side of the blade distal end portions 40d than on the second surface 60b on the side of the support plate 50. Because the inclination heading from the outer peripheral side toward the inner peripheral side is greater on the first surface 60a than on the second surface 60b on the side of the support plate 50, removal of the molded product becomes easy when detaching the mold from the fan block 30 while rotating the mold about a place near the blade distal end portions 40d after injection molding, for example.
  • a mold with this way of removal has parting faces plurally divided about the axial centre O, for example. In this way, yield is improved because integral molding becomes easy, and the manufacturing costs of the cross-flow fan 10 can be reduced.
  • the plural blades 40 are disposed in such a way that their outer ends 40a are positioned concentrically about the axial centre O.
  • the auxiliary ring 60 has a circular annular shape where its outer peripheral surface 60c runs along the outside of the outer ends 40a of the plural blades 40. Because the outer peripheral surface 60c of the auxiliary ring 60 runs along the outside of the outer ends 40a of the blades 40, the outer peripheral surface 60c of the auxiliary ring 60 is continuous without being interrupted by the outer ends 40a. Because of that, the strength of the auxiliary ring 60 can be increased so that the effect of reinforcing the strength of the cross-flow fan 10 can be improved.
  • the auxiliary ring 60 has a circular annular shape and has the outer radius r3 larger than the outer radius r1 of the support plate 50.
  • the outer radius r3 of the auxiliary ring 60 is equal to or larger than the outer radius r1 of the support plate 50, the interval between the outer peripheral surface 60c of the auxiliary ring 60 and the outer ends 40a of the blades 40 can be increased so that the strength of the auxiliary ring 60 can be increased.
  • the effect of reinforcing the strength of the cross-flow fan 10 can be improved.
