(structure in row ice portion 9)
As reference Fig. 5 (a) description, in the manner, limiting unit 4 is made up of the wind gate cover side protuberance 29 of wind gate cover 2 and the rotation side protuberance 39 of rotary body 3.Therefore, wind gate cover side protuberance 29 with rotate side protuberance 39 close to time, the ice produced because of the water freezing condensed at the outer peripheral face of rotary body 3 is handled upside down by groove 27 and projecting strip part 37, as shown in Fig. 5 (b), ice P can be clamped in wind gate cover side protuberance 29 and rotate between side protuberance 39.
Therefore, in the manner, lean on the position of radial outside to be configured with row ice portion 9 (wind gate cover side row ice portion 9a) in the end 290 of the counter clockwise direction CCW side around central axis relative to wind gate cover side protuberance 29 (side around central axis L) of wind gate cover 2, wind gate cover side protuberance 29 with rotate side protuberance 39 close to time, as shown in arrow Wa, row ice portion 9 (wind gate cover side row ice portion 9a) makes ice P discharge between wind gate cover side protuberance 29 and rotation side protuberance 39 to radial outside.
In the manner, be formed with the wind gate cover side projecting strip part 231 of the end side (side L1) in central axis L direction along the opening edge extension in rotary body configuration hole 20 at wind gate cover 2, wind gate cover side protuberance 29 is outstanding to radially inner side from wind gate cover side projecting strip part 231.Therefore, in the manner, be formed with breach at wind gate cover side projecting strip part 231, constitute by described breach wind gate cover side row's ice mouth 299 that ice portion 9a is arranged in wind gate cover side.In described wind gate cover side row's ice mouth 299, being positioned in face 299a, 299b that circumference is opposed becomes towards the inclined plane making the direction more more leaving face 299a by the part of radial outside tilt around the face 299b of the clockwise direction CW side (opposite side around central axis L) of central axis.Therefore, the circumferential size of the radial outside of wind gate cover side row ice mouth 299 is larger than the circumferential size of radially inner side.
And, the end 290 of the counter clockwise direction CCW side (side around central axis L) of wind gate cover side protuberance 29 comprise can with rotate wind gate cover side abutting part 292 that side protuberance 39 abut and than wind gate cover side abutting part 292 by the surface of position of radial outside to the wind gate cover lateral incline 293 of radial outside, wind gate cover lateral incline 293 is formed and the face 299b continuous print inclined plane 295 of the clockwise direction CW side of ice mouth 299 is arranged in wind gate cover side.Therefore, the radial width size of the inclined plane that the face 299b that the radial dimension ratio of wind gate cover side abutting part 292 arranges the clockwise direction CW side of ice mouth 299 by wind gate cover lateral incline 293 and wind gate cover side is formed is little.
(main efficacy results of the manner)
