Abstract:
1. An arrangement for a quick positioning of a motor of a cross-flow fan, comprising: a) a housing having a first plate, a second plate and an L-shaped wind deflector between the first and second plates, the first plate having a first mounting hole, the second plate having a second mounting hole with a greater diameter than the first mounting hole, a convex ring and several securing lugs being arranged around a rim of the second mounting hole on the second plate; b) a cross-flow fan having a shaft at a first side thereof positioned within the first mounting hole, a third mounting hole being axially formed at a second side of the cross-flow fan for accommodating a shock-absorbing body, the shock-absorbing body being provided with a shaft-retaining hole in an axial direction; and c) a motor apparatus having a motor body and a mounting base, the mounting base being disposed at a side of the motor apparatus facing a driving shaft of the motor body, the mounting base having a mounting member and a flange member, the mounting member being matched to the convex ring for a tight insertion into the second mounting hole, the flange member being formed around a rim of the mounting member and snugly secured to the convex ring, an external side of the flange member being provided with projecting ears corresponding to the securing lugs of the convex ring, the projecting ears being secured to the securing lugs by screws such that the motor apparatus may rapidly and precisely fit into the second mounting hole, the driving shaft being extended into the shaft-retaining hole of the shock-absorbing body of the cross-flow fan for imparting rotary motion to the cross-flow fan; wherein a projecting shaft support is fitted to a side of the motor body to accept the driving shaft; and wherein a fourth mounting hole is formed at the center of the mounting member of the mounting base, the fourth mounting hole coaxially receiving the projecting shaft support therein.
