It is therefore not necessary to make the entrance opening or the sectors narrow to limit the number of ice pieces entering, and mutual blockage of the ice pieces at the entrance opening or in a sector can be largely avoided. This also contributes to the fact that the number of pieces of ice, which enters a sector of the chamber when it passes through the inlet, varies only slightly.

Due to its planar shape, unlike a helix or a worm, it exerts no conveying force in the axial direction on pieces of ice contained in the collecting container 6, but moves them in random directions and thus prevents them from freezing over a large area. Therefore, the stirring rod 9 can be rotated from the motor 7 from time to time even if no ice is to be dispensed.

  • Fig. 4 shows the chamber 10 in a closed configuration in which edges 34, 35 of the sheets 30, 31 meet in a lower region of the chamber 10, on the left side of the plane 32. Ice dispensing is not possible in this configuration. Since the swing arm 28 is pulled out of the discharge chamber 10, the cutter discs 16, 17 are rotatable with the stirring rod 9, and the knives 11 push pieces of ice which have come into the discharge chamber 10 by the movement of the stirring rod 9 in front of them. In order to form an outlet opening 36 of the chamber 10, the sheet 30 is pivoted about its axis 33 in a clockwise direction, as shown in Fig. 5, so that the edges 34, 35 of the sheets 30, 31 apart and between them the outlet opening 36 is formed.

If the dimensions of the sectors 37 limit the number of pieces of ice entering each passage of the inlet opening 29, the inlet opening 29 can be generously dimensioned.

Due to the staggered orientation of the cutting discs 13, 14, 15, a piece of ice is not clamped between more than two knives 1 1 and 20 at the same time. Therefore, a single piece of ice can not block the rotation of the stirring bar 9. Since the blades are prevented from axial movement by the spring washer 24, the bridge portions 27 are also substantially immobile during the crushing operation, and a slight overlap between the pivot arm 28 and the bridge portion 27 is sufficient to reliably block the knives 20 and release to prevent.

Abstract

L'invention concerne une unité de dosage de glace pour une machine à glace, laquelle unité comprend une chambre qui est subdivisée en secteurs par plusieurs ailettes disposées à rotation autour d'axe sensiblement horizontal et présente une ouverture d'entrée et une ouverture de sortie. Dans chaque position des ailettes dans laquelle l'ouverture d'entrée recouvre suffisamment un des secteurs pour permettre le passage d'un glaçon par l'ouverture d'entrée dans ce secteur, un recouvrement de ce même secteur par l'ouverture de sortie est trop minime pour permettre au glaçon de sortir du secteur par l'ouverture de sortie.
