  • the bearing body is expediently in turn lockable to the frame.
  • this bearing body comprises a pin which axially slidably engages in an opening of an end wall of the frame, and arranged in the interior of the frame, in the radial direction over the pin protruding projection, and a bolt is in a space between the projection and the front wall insertable. If the bolt is removed, then the projection back to the front wall, and the ice tray can disengage from a receptacle of an opposite end wall of the frame.
  • Such a bar is expediently U-shaped with two legs, wherein the legs engage on both sides of the pivot axis of the ice tray between the projection and the end wall.
  • a recess in the end wall, which receives the bearing body be designed open-edge.
  • a journal of the ice tray is preferably connected torque-tight and inserted into one another in the axial direction.
  • the bearing body of the first bearing is preferably movable far enough to cancel the mated connection of the shell with the bearing body of the second bearing.
  • the plugged connection of the ice tray with the bearing body of the second bearing is playful around an axis orthogonal to the pivot axis of the ice tray, it is sufficient if the ice tray can be pivoted about the orthogonal axis in an inclined position in the unlocked state of the bearing body of the first bearing, in the it can finally be taken out of the frame.
  • the ice tray can be exchanged with only a few manipulations and without special knowledge and without any tools, it is possible alternatively to use different ice trays with differently shaped compartments in order to produce differently shaped ice cubes.
  • Fig. 1 shows an automatic ice cube maker according to the present invention in an exploded perspective view. It comprises an ice tray 1 in the form of a groove, which is closed at their end faces in each case by transverse walls 2 and divided by uniformly spaced intermediate walls 3 in a plurality of identically shaped compartments 4, here seven pieces, with semi-cylindrical bottom. While the intermediate walls 3 are flush with the longitudinal wall 5 facing away from the observer, the longitudinal wall 6 facing the observer is extended beyond the upper edges of the intermediate walls 3. While the intermediate walls 3 are exactly semicircular, the transverse walls 2 in each case corresponding to the projection of the front longitudinal wall 6 on a sector 7 extending beyond the semicircular shape.
  • the ice tray 1 is shown in a tilted position, in which the upper edges of the sectors 7 are substantially horizontal, while the intermediate walls 3 to the longitudinal wall 6 are downhill.
  • the ice tray 1 may be a plastic molded part; Preferably, due to the good thermal conductivity, it is designed as a cast aluminum.
  • a cable drum 11 On one of the transverse walls 2 of the ice bowl 1, a cable drum 11 is mounted; it serves for the sheltered accommodation of a coiled supply cable 12, which is used to power a not visible in the figure, mounted on the underside of the ice tray 1 heater 13 (see Fig. 9 ) serves.
  • the ice bowl 1 lies completely within an imaginary hollow cylinder defined by the jacket surface of the cable drum 11, which at the same time represents the smallest possible cylinder into which the ice bowl 1 fits.
  • a journalled from the transverse wall 2 facing the viewer extends on the longitudinal center axis of the cable drum 11.
  • a corresponding, from the second transverse wall through the cable drum 11 extending journal is not visible in the Fig.
  • a plastic core hub 50 is provided to be mounted in an entangled manner with the umbilical 12 in the cable drum 11.
  • a molded plastic frame is designated 15. It has an upwardly and downwardly open cavity 16 which is provided to mount the ice tray 1 therein. On the end walls 17, 18 of the cavity 16 are a tubular Bearing bush 19 or a keyhole-like, downwardly open-edge recess 20 for the pivotal mounting of the ice tray 1 is formed.
  • a longitudinal wall of the cavity 16 is formed by a box 21 which is provided to receive a drive motor 22 as well as various electronic components for controlling the operation of the icemaker.
  • the frame is shown with a second longitudinal wall 65 opposite the box 21; this longitudinal wall 65 can be omitted if the frame is stiff enough even without them to keep the ice bowl 1 safe.
  • a pinion 23 is mounted, which in the FIGS. 3, 4 . 6 respectively 8 is better to see than in FIG. 2 ,
  • the pinion 23 takes place in a cavity 24 of the end wall 17. It forms there with a gear 25, a reduction gear.
  • the gear 25 carries a projecting in the axial direction pin 26 which is provided to engage in a vertical slot 27 of a vibrating body 28.
  • the oscillating body 28 is guided horizontally displaceable by means of the pin 29 protruding into the cavity 24 from the end wall 17 and engaging in a horizontal slot 30 of the oscillating body.
  • a toothing 31 formed on a lower edge of the oscillating body 28 meshes with a toothed wheel 32, which is integral with a shaft journal 14 of the ice bowl 1 rotatably receiving, rotatably supported in the bearing bush 19, in Fig. 10 Connected to 8 bearing body is connected.
  • a to be screwed on the open side of the end wall 17 cover plate 33 closes the cavity 24.
  • a mounting flange 34 with laterally beyond the end wall 17 protruding tabs 35 is used for mounting the icemaker in a refrigerator.
  • a bottom plate 36 closes from below the box 21st
  • Fig. 2 shows, seen from the side of the end wall 18 and the box 21 ago, in a perspective view of the ice maker with the ice bowl 1 in a tilted position.
  • the upper edges of the sectors 7 on the transverse walls 2 of the ice tray 1 are horizontal.
  • Fig. 3 shows a frontal view of the ice maker from the side of the end wall 17, wherein cover plate 33 and mounting flange 34 are omitted to look into the Cavity 24 of the end wall 17 to give free.
  • the configuration shown here is the one where the icemaker is assembled.
  • Various markings indicate a correct positioning of individual parts relative to each other.
  • a first pair of markings 37, 38 is located on the end wall 17 itself, or on the gear 26 carrying the pin 26. If these markings 37, 38, as shown in the figure, are exactly aligned with each other, the pin 26 is located in a three o'clock position, that is, on the right-most point of his path, which he can reach.
  • the mounted on the pin 26 and the stationary pin 29 vibrating body 28 is located at the right turning point of its path.
  • Arranged markings 39, 40 on a protruding beyond the sprocket flange 41 of the gear 32 and on the end wall 17 show a correct orientation of the gear 32 and consequently also with its journal 14 in a cross-sectionally T-shaped recess of the gear 32nd engaging ice tray 1.
  • An inherently redundant pair of markers 42, 43 on the teeth 31 of the pivot body 28 and the gear 32 indicates the correct positioning of the gear 32 and the oscillating body 31 with respect to each other.
  • a sensor 44 for detecting the rotational position of the gear 32 is mounted adjacent thereto. It cooperates with a rib 45 projecting from the edge of the flange 41 on a part of its circumference in the axial direction, so that it can dive into a slot at the rear of the sensor housing. In the tilted position of Fig. 3 For the most part, the rib 45 is covered by the sensor 44 and the vibrating body 28.
  • Fig. 4 differs from Fig. 3 in that the housing of the sensor 44 is shown partially cut open, so that two photocells 46, 47 bridging the slot can be seen in its interior.
  • the rib 45 is located just above the two light barriers 46, 47 so that an unillustrated control electronics based on the fact that both light barriers are open, can recognize that the ice bowl 1 is in the tilted position and the drive motor 22 can stop to hold the ice tray 1 in the tilted position and be able to fill.
  • the drive motor 22 is set by the control unit in motion to bring the ice bowl 1 in the upright position in which the Amounts of water in the compartments 4 of the ice tray 1 are neatly separated from each other.
  • This position is in Fig. 5 in a perspective view accordingly Fig. 2 and in Fig. 6 in a frontal view accordingly Fig. 4 shown.
  • the gear 25 is opposite to the position of Fig. 4 rotated in the clockwise direction, but the same position of the ice tray 1 could also be achieved by a rotation of the gear 25 in the counterclockwise direction.
  • the achievement of the upright position is recognized by the fact that the rib 45 begins to obstruct the lower light barrier 47.
  • the ice tray 1 In the upright position, the ice tray 1 remains standing for a while until the water in the compartments 4 is frozen.
  • the standing time in the upright position can be fixed;
  • the control circuit may also be connected to a temperature sensor to determine a sufficient time at the measured temperature for freezing the water on the basis of a measured temperature in the vicinity of the ice tray 1 and a characteristic curve stored in the control circuit.
  • this heating device 13 is a bent into a loop electric heating element, which extends in close contact with the tray 1 between protruding from the bottom heat exchanger ribs 49 therethrough and partly in a formed on the underside of the ice bowl 1 groove 48 is included.
  • the pieces of ice in the subjects 4 are thawed superficially.
  • the water layer thus produced between the tray 1 and the pieces of ice acts as a sliding film on which the pieces of ice are movable with very little friction. Due to the cylinder segment cross-sectional shape the fan 4 slide the pieces of ice easily out of the compartments 4 and fall into a not shown, arranged under the icemaker receptacle.
  • the drive motor After draining the compartments 4, the drive motor is set in motion again, and the gear 25 is further rotated clockwise until it returns to the in Fig. 2 to 4 reached position shown and a new operating cycle of the icemaker begins.
  • Fig. 10 illustrates the suspension of the ice tray 1 in the above-described ice maker on the basis of a section along the pivot axis of the ice tray 1.
  • the axle journal 14 is inserted into the integrally connected to the gear 32 bearing body 8.
  • radially protruding ribs of the axle journal 14 engage in grooves of the bearing body 8 and thus establish a rotationally fixed connection.
  • the head piece 59 is located in the inner cavity 16 of the frame 15 and is from the inside of the end wall 18 by a in Fig. 11 held in perspective view latch 60 spaced.
  • the bolt 60 for example, made of spring plate comprises two U-shaped connected, curved legs 61 which engage around the narrower portion 58 of the pin 56 on both sides and thereby elastically press against facing surfaces of the end wall 18 and the head piece 59.
  • the ice bowl 1 is held between the two bearing bodies 8, 9 with negligible play in the axial direction and in radial directions.
  • Fig. 12 shows a section through a central region of the end wall 18 with the recess 20 and engaging in the recess 20 bearing body 9.
  • the outer, larger portion 57 of the pin 56 fills a circular upper end portion 62 of the recess 20 substantially completely.
  • the end portion 62 is followed at the bottom by a slot 63 whose width is smaller than the diameter of the portion 57 and slightly larger than that of the portion 58.
  • the slot 63 does not pass.
  • the latch 60 When the latch 60 is removed, it is possible to displace the bearing body 9 outwardly in the axial direction so that the portion 57 fully disengages from the recess 20 and instead the portion 58 is therein.
  • the engagement depth of the pivot pin 14 in the bearing body 8 is slightly smaller than the distance between the end wall 18 and the head piece 59 maintained by the bolt 60, so that when the head piece 59 is brought into contact with the end wall 18 after removal of the bolt 60 , the engagement of the axle journal 14 is lost in the bearing body 8. Since the now engaging in the recess 20 portion 58 of the bearing body 9 is narrow enough to pass through the slot 63, the ice tray 1 can be removed from the frame 15 down. Since the ice tray 1 can be removed in a horizontal orientation, the spillage of water can be avoided if the ice tray 1 at the time of their removal contains.
  • Fig. 13 shows in an exploded perspective view in each case a part of the end wall 18 and the ice bowl 1 according to a second embodiment of the invention.
  • the bearing body 9 facing away from the motor, in which the axle journal 54 rotatably engages, is clamped in a recess 20 of the end wall 18 by a bracket 64 engaging in the recess 20.
  • the bracket 64 has two elastic spring arms, which engage in notches 66 of the recess 20 engaging latching lugs 67 and are guided by laterally protruding fingers 68 along the edges of the recess 20. By squeezing the spring arms 65, the locking lugs 67 can be released from the notches 66 and the bracket 64 are removed.
  • Fig. 14 shows the motor-side end of the ice tray 1 in section.
  • the engaging in the motor-side bearing body 8 journal 14 here has a square cross-section, and the bearing body 8 has a recess 69 for the torque-locking receiving the axle journal 14, the height of which the ice bowl 1 facing the end of the bearing body 8 increases towards.
  • This makes it possible to fix the ice tray 1 in the bearing body 8 substantially free of play, as long as the opposite bearing body 9 is locked; However, if the bearing body 9 is unlocked, it can be raised in the recess 20 and with it the ice tray 1 are pivoted, as indicated by a dashed outline in Fig. 14 presented until it finally becomes possible, the Axle 14 completely pull out of the bearing body 8 and remove the ice tray 1.
