In the present embodiment, identical with the first above-mentioned embodiment, be provided with vertically arranged rotating shaft 45 in the feed path 15, horizontal proliferation blade 43 is fixed in the rotating shaft 45.

The top of horizontal proliferation blade 43 is formed with a hinged projection 45d.This hinged projection 45d has a predetermined angular corresponding to the plane of horizontal proliferation blade 43.On hinged projection 45d, be formed with one outstanding downwards with the swivel pin 45e parallel with rotating shaft 45, this swivel pin 45e interacts with the control stick 115 that will narrate hereinafter.

In the present embodiment, the structure of drive motor 109 and cam 101 is basically the same as those in the first embodiment.That is, cam 101 has a cam body 103, a cam path 105 and a camshaft 106 that is arranged on the cam body 103.Yet in the present embodiment, the direction of cam 101 is different with first embodiment's.In other words, cam 101 flatly is provided with as in first embodiment, just on direction perpendicular to the cam 51 of first embodiment.

Drive motor 109 is fixing by the motor bracket on the posterior face that is installed in channel plate 27 110.One end of camshaft 106 links to each other with the driving shaft of drive motor 109, and its other end is inserted on the rear wall that is arranged at channel plate 27 rear portions.Therefore, cam 101 is being supported rotationally.Also fixing a ways 117 parallel on the rear wall 29 with camshaft 106.

Ways 117 has a gathering sill that forms along its longitudinal direction (not shown go out), and guide post 115 passes ways 117 by this gathering sill.At the middle body of control stick 115, be provided with a pair of guide plate 116.This guide plate 116 is arranged on the both sides of ways 117, makes its contact.Guide plate 116 supports control stick 115, makes control stick 115 keep vertical with ways 117, thereby control stick 115 can be slided along the gathering sill of ways 117.

One end of control stick 115 is inserted in the cam path 105, and its other end is formed with a groove 111 that receives swivel pin 45e.Therefore, when control stick 115 when the longitudinal direction of ways 117 moves, swivel pin 45e moves along groove 111, thus horizontal proliferation blade 43 is as Figure 21 and shown in Figure 22 the rotation.

Therefore, when cam 101 under the driving of drive motor 109 and when rotating, control stick 115 moves back and forth under the effect of cam 101, and horizontal proliferation blade 43 back and forth rotates in a predetermined angular range therefrom.Therefore, cold air flatly spreads.

As mentioned above,, can realize steady flow and the evenly distribution of cold air on vertical and horizontal direction, the phenomenon of air-swirl can not take place near the cold air outlet according to the present invention.

Although the present invention is had been described in detail, should be interpreted as clearly that this is only used for illustrating and giving an example, be not to be used for limiting, wherein the spirit and scope of the present invention are by the claim limit of appended claims.
