Definitions
- Dispensing opening of the ice crushing unit transported. If, however, the second set of blades is found on the housing, it blocks the path of the ice pieces to
- the second set of knives when fixed to the housing, tends to disengage and temporarily rotate together with the first set of knives until the detection again takes hold. During this time pieces of ice may be issued intact, although this is not desired by the user.
- Object of the present invention is to provide an ice crushing unit, which provides a high degree of security against unwanted co-rotation of the second set of blades.
- Each knife set preferably comprises at least one knife disc with a ring pushed onto the shaft and a plurality of knives radially projecting from the ring.
- the second set of knives comprises at least two such knives
- the free ends of the knives of different knives of the second set of knives are preferably interconnected, so that the knives of the second set can only rotate together or not at all.
- Figure 1 is a schematic section through a household refrigerator, which is equipped with an ice crusher according to the invention.
- Fig. 2 shows a section through an ice storage container with integrated
- Fig. 3 is an exploded view of the shaft and the blades of the crushing unit of Fig. 2;
- FIG. 4 shows a radial section through the ice breaking unit of FIG. 2 with the discharge opening closed
- FIG. and Fig. 5 is a radial section through the Eiszerklein mecanicstician open dispensing opening.
- the refrigerating appliance shown in a schematic section in FIG. 1 has a heat-insulating body 1 and a door 2 which delimit an interior space 3.
- Interior 3 is maintained at a temperature below 0 0 C by an evaporator, which is housed in an upper part of the body 1 divided evaporator chamber 4.
- An automatic ice maker 5 is in the immediate vicinity of
- Evaporator chamber 4 arranged in the interior 3, so that it can preferably be acted upon with cold air from the evaporator chamber 4.
- the ice maker 5 comprises in a known manner, not shown in detail in the figure, a plurality of
- Molded containers means for automatically dosing water into the mold containers and means for automatically ejecting the finished pieces of ice from the mold container.
- a collecting container 6 of an ice dispenser is arranged, which receives the ejected pieces of ice.
- the collecting container 6 extends over a large part of the depth of the interior 3.
- an electric motor 7 is housed, which drives via an adapter part 8 in the longitudinal direction of the collecting container 6 extending stirring rod 9.
- the adapter part 8, which carries a rear end of the stirring rod 9, is rotatably but axially immovably held in an opening in the back of the collecting container 6.
- An output shaft of the electric motor 7 engages positively in rear recesses of the adapter part 8 in order to drive the stirring rod 9.
- the collecting container is guided in the body 1 on rails and pulled out; when it is pulled out, the engagement between the output shaft of the motor 7 and the adapter part 8 is lost; when reinserting the collecting container 6, the intervention is restored.
- the rake 9 is a zigzag in a plane parallel to its axis of rotation and straight at a front end along the axis of rotation extending metal rod. Because of its planar shape, it practices, unlike a helix or a Snail, no conveying force in the axial direction on Eisump publishede contained in the collecting container 6, but moves them in random directions, thus preventing 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.
- an output chamber 10 through which the straight end section 12 of the stirring rod 9 extends, adjoins the collecting container 6 on the side facing away from the motor 7.
- the end portion 12 carries a plurality of rotatable blades 11, which are used for crushing brought by rotation of the stirring rod 9 in the discharge chamber 10 ice pieces.
- Function and arrangement of the knife 1 1 is more clearly with reference to FIG. 3, which shows the stirring rod 9 and arranged at her components of an ice crushing unit, to which the knife 1 1, in exploded view.
- two types of cutting discs 13, 14, 15 and 16, 17 are arranged.
- All knife discs each have a central ring 19 with an opening through which the end portion 12 extends, and from the ring radially projecting knives 1 1 and 20.
- the opening of the ring 19 each out of round and adapted to the Ouerten of the end portion 12, so that these cutting discs 13, 14, 15 are entrained by a rotation of the stirring rod 9.
- the orientation of the knives 11 with respect to the opening of the ring 19 is slightly different in the case of the three cutter disks 13, 14, 15, so that the blades 11 are not aligned with one another when the cutter disks 13, 14, 15 are mounted on the end portion 12 are.
- the rings 19 of the cutting discs 16, 17 each have larger openings that allow rotation of the cutting discs 16, 17 with respect to the stirring rod 9.
- the cutter disks 13 to 17 are each held by plastic buffers 21, 22 of substantially cylindrical shape from one another and by a flange 23 fixed to the stirring rod 9.
- the buffers 21, 22 and cutter discs 13 to 17 are pressurized in the axial direction by a spring washer 24 which is clamped between the foremost buffer 21 and a washer 26 secured by a circlip 25 at the tip of the stirring rod 9.
- the spring washer 24 ensures that regardless of Manufacturing tolerances and regardless of different coefficients of thermal expansion of the stirring rod 9, the cutting discs 13 to 17 and the buffers 21, 22, the cutting discs 13 to 17 between the buffers 21, 22 are clamped so that they do not dodge appreciably in the axial direction on the one hand when crushing ice, on the other the stirring rod 9 with the cutting discs 13, 14, 15 remains rotatable, even if the cutting discs 16, 17 are locked to the walls of the discharge chamber 10.
- Configuration blocks the pivot arm 28, a rotation of the cutter discs 16, 17, and in the discharge chamber 10 occurred pieces of ice each before reaching the Opening 32 between the rotating blades 11 and the knives 20 crushed.
