  • a plate (second ice breaking member) 602 and a drive mechanism 603 for moving the movable plate 601 in the direction (arrow 604) close to the fixed plate 602 and the opposite direction are provided.
  • the arrangement of the movable plate 601 and the fixed plate 602 may be opposite to each other. Further, both the first and second ice breaking members may move.
  • the ice breaking mechanism 600 is supplied with ice (first ice) produced by the ice making unit 20 provided at the top of the ice breaking mechanism 600. As shown in FIG. 11, the ice breaking mechanism 600 breaks the ice by sandwiching the ice between the planar surface 602a of the fixed plate 602 and the planar surface 601a of the movable plate 601, and serves as second ice. To produce crash ice.
  • the surface contacts the first ice, so the contact area with the ice is wide and the pressure applied to the ice Is relatively small.
  • the tip of the sharp blade structure contacts the ice, so the contact area with the ice is narrow and the pressure locally applied to the ice is large.
  • the ice breaking ability of the ice breaking mechanism 600 in the sixth embodiment is lower than the ice breaking ability of the ice breaking mechanism using the blade structure.
  • ice 110 having a cavity that is easily crushed is supplied to the ice breaking mechanism 600 by an ice making unit similar to the ice making unit 20a of the first embodiment. For this reason, ice breaking by sandwiching the surface 602a of the fixed plate 602 and the surface 601a of the movable plate 601 is possible.
  • both the surface 602a and the surface 601a are flat surfaces.
  • the ice breaking mechanism 600 does not have a blade structure, but performs ice breaking by sandwiching the surface 602a of the fixed plate 602 and the surface 601a of the movable plate 601. Damage to parts is unlikely to occur.
  • ice having a cavity that is easily crushed is supplied from the ice making unit 20a to the ice breaking mechanism 600, so that it is difficult for components to be damaged and the drive mechanism 603 is broken. hard.

Abstract

L'invention concerne un distributeur de glaçon (50) comprenant une unité de production de glaçon (20) destinée à produire un premier type de glaçon (110), un mécanisme de broyage de glaçon (500, 600) destinée à produire un second type de glaçon au moyen du broyage de la première glaçon fournie à partir de l'unité de production de glaçon, et un mécanisme de distribution (37) destiné à distribuer le second type de glaçon. L'unité de production de glaçon (20) comporte un plateau de production de glaçon (111) comprenant une pluralité de compartiments individuels de production de glaçon (112) correspondant à la forme du premier type de glaçon, une unité d'alimentation en eau (26) destinée à alimenter en eau le plateau de production de glaçon, et une unité de refroidissement (24a) destinée à refroidir l'eau alimentée au plateau de production de glaçon ; le premier type de glaçon est un glaçon (110) à partie centrale creuse, un glaçon (120) prenant une forme cuboïde ayant un côté plus court que les deux autres côtés, ou un glaçon (130) prenant une forme de colonne triangulaire ; et le mécanisme de broyage de glaçon (500, 600) comporte une pluralité d'éléments de broyage de glaçon (501, 502, 601, 602) comprenant une pluralité de faces entre lesquelles le premier type de glaçon est introduit et destinées à produire le second type de glaçon par broyage du premier type de glaçon au moyen de la réception d'une force d'entraînement et du rétrécissement de l'espace entre les faces, et une unité d'entraînement (503, 603) destinée à appliquer la force d'entraînement.
