Abstract

An ice maker comprises a mold container (1) which is open on one side and at least one Peltier element (4) for cooling the mold container (1). The mold container (1) is movable on a frame (10) between a position in which the opening of the mold container (1) is directed upward and a position in which the opening is directed downward.

Description

  • The present invention relates to an ice maker having a mold container open on one side and at least one Peltier element for cooling the mold container and producing a piece of ice therein. Such an icemaker is out DE 100 62 663 C2 known.
  • Of the mold container this icemaker is fixedly mounted with respect to a storage container for finished pieces of ice and becomes through a dipping from above, by the open side, into it liquid supply filled. If one in the mold container filled Amount of water is frozen by the action of the Peltier element, becomes the direction of the electric current flowing through the Peltier element Current reversed temporarily, so that the Peltier element heats the mold vessel, instead of him to cool. This thaws the ice in the mold container superficial and can by lifting the liquid supply, at which it is frozen, from the mold container to a stripping device be lifted out. Before the piece of ice the scraper reached, a slide is inserted between it and the mold container, so that the piece of ice, when it passes through the wiper finally from the liquid supply is stripped, falls on the slide and on this in one Clippings for finished Ice pieces glide.
  • This conventional Ice maker has a considerable Number of moving parts and needs space for their Movements.
  • task The present invention is an ice maker with a Peltier element To specify that is simple and compact in construction and with a small Number of moving parts.
  • The Task becomes according to claim 1 solved by that the mold container even on a frame between a position in which the opening of the freezing container directed upward and freeze water in the mold vessel can, and a position is movable, in which the opening downwards is directed, so that the finished ice body, powered by own weight, the mold container can leave.
  • There the movement of the mold container essentially comprises a rotation, it is executable in a small space, in particular when an axis of rotation is in close proximity to the mold vessel, preferably centrally through this, runs.
  • Around To ensure good thermal contact is the Peltier element preferably on a surface of the mold container firmly mounted and movable with this.
  • Around a big cooling capacity available too and needed to freeze To make the time span short is preferably at least one pair mounted by Peltier elements on opposite sides of the mold container.
  • Around a reflux of heat to avoid from the warm side of the Peltier element to the mold container, is preferably each Peltier element in a surrounding the mold container Layer embedded from an insulating material.
  • These Layer is preferably arranged so that it has a gap between the mold container and fills a heat sink, the is connected to the Peltier element to the waste heat of to leave its warm side.
  • one preferred embodiment, according to a supply line for fresh water through a wall of the mold container guided. This arrangement makes it possible to use the pressure of the supplied fresh water to a finished piece of ice from the mold container expel.
  • The Supply line for Fresh water should also expediently at a side facing away from the opening Bottom of the mold container lead to it a possibly projecting into the lead projection of the ice chunk of Do not solve with special needs.
  • alternative is possible, too, that a supply line for Fresh water a fixed orifice over the opening of the mold container in the upward position, so that between the finished ice cream piece and the mouth There can be no connection that could hinder the loosening of the piece of ice.
  • Preferably wears the freezing container a rotatably suspended in the frame Shaft on which a mounted in the frame engine can attack.
  • Of the Ice maker according to the invention Due to its compact shape, it is well suited for use in a refrigerated interior a household refrigerator.
  • Further Features and advantages of the invention will become apparent from the following Description of exemplary embodiments with reference to the attached Characters. Show it:
  • 1 a perspective view of a first embodiment of the ice maker according to the invention;
  • 2 the icemaker off 1 partially cut open;
  • 3 a schematic section through another embodiment of the ice maker; and
  • 4 a third embodiment of the ice maker in a zu 2 analog view.
  • Centerpiece of in 1 The ice maker shown is a solid aluminum block with a cylindrical recess 2 , which is a shaped body 1 for each forming an ice cube to be produced. The molded body 1 is on five sides of an isolation layer 3 , For example, from a foamed plastic, surrounded. Like the sectional view of the 2 shows are on two opposite sides of the molding 1 each window in the insulation layer 3 cut, which is a peltier element 4 take up. A main page of Peltier elements 4 is in direct contact with the surface of the molding 1 the other side is in direct contact with a projection of a heat sink engaging in the window 5 , on its side facing away from the projection side a plurality of narrow ribs 6 wearing.
  • In order to increase the cooling performance of the ice maker, another pair of Peltier elements could be attached to the other two side walls and / or a single Peltier element to the underside of the shaped body 1 to be appropriate.
  • A flexible fresh water supply line 7 flows through a central bore 8 at the bottom of the recess 2 ,
  • Two collinear shaft sections 9 are each on the heat sinks 5 attached. The wave sections 9 are each rotatably suspended in a frame of the ice maker, wherein for the sake of simplicity only for one of the shaft sections 9 a piece of a rack plate 10 and a rolling bearing 11 are shown, in which the shaft portion 9 rotatable on the frame plate 10 is suspended.
  • The operation of the ice maker is as follows: While the molded body 1 in the in 1 and 2 shown position, a metered amount of water through the supply line 7 in the recess 2 fed. At the same time, the Peltier elements 4 fed with a direct current (eg via the metallic shaft sections 9 can be conducted) whose sign is chosen so that the Peltier elements 4 at her the molding 1 cool facing surface and on her the heat sink 5 facing surface heat. As a result, the contents of the recess freezes in a few minutes 2 , After a fixed period of operation, a control circuit, not shown, reverses the direction of the supply current through the Peltier elements 4 around. The time span, depending on one of a near the shaped body 1 arranged temperature sensor can be preset measured temperature, so that it is freezing the water in the recess 2 sufficient. The relationship between cooling time of operation and measured temperature may be determined empirically.
  • Once the predetermined period of time has elapsed, the control circuit returns the direction of the supply current of the Peltier elements 4 so that these are the shaped body 1 heat. Thus, a thin layer of water forms on the surface of the recess 2 ice cubes contained. Along with reversing the direction of the supply current, the control circuit also actuates one on one of the shaft sections 9 attacking electric motor 12 to the molding 1 as indicated by the arrow P in 1 indicated to turn 180 ° with the opening down. As a result of the water layer between him and the molding 1 easily moving ice piece slides out of the recess 2 out and falls into a storage container located below 13 ,
  • A modified embodiment of the ice maker according to the invention is in 3 shown in a schematic section. Like the icemaker 1 and 2 includes the one of 3 a massive molded body 1 made of aluminum with a central recess 2 and two opposite outer sides of the shaped body 1 arranged Peltier elements in the 3 are not visible because they are outside the cutting plane.
  • The molded body 1 is constructed of a base plate 17 and a hollow top, attached to the bottom plate about an axis 15 pivotally hinged, extending along a lower edge of the upper part 18 perpendicular to the cutting plane of the 3 extends. The upper part rests in a position shown by solid lines 18 on the bottom plate 17 , and the recess 2 is through an elastomeric sealing ring 16 between shell 18 and bottom plate 17 sealed. The motor 12 serves to pivot the upper part 18 around the axis 15 , A supply line 7 for fresh water flows through a hole 8th the bottom plate 17 in the recess 2 of the molding. The recess 2 is to the bottom plate 17 rejuvenated.
  • Again, to produce a piece of ice first a metered amount of water through the supply line 7 in the recess 2 admitted, and the Peltier elements are energized to the molding 1 to cool and the water in the recess 2 to freeze. After a sufficient period of time, the supply current of the Peltier elements 4 inverted to superficially build up the piece of ice, and the shaped body 1 is by the electric motor 12 in the in 3 dashed position shown tilted. Because the recess 2 also tapers down, the piece of ice can not during the tilting from the lower opening 14 slip out of the top and on the bottom plate 17 to lie down. In the dashed position, however, the piece of ice from the recess can slide freely; since the bottom of the piece of ice is exposed, this is sufficient for a minimum thickness of the water layer between the ice and the molding 1 after reversing the direction of the supply current of the Peltier elements.
  • 4 shows a modification of the ice maker of 1 and 2 in which instead of a water supply through the hole 8th in the bottom of the molding 1 a feeder over one above the recess 2 Stationarily arranged supply line 19 is provided. Into the drilling 8th whereas there is a valve 20 inserted, which in the illustrated position of the molding 1 is tight.
  • If the water in the recess 2 is frozen and the shaped body 1 with the help of the engine 12 is rotated, and the Peltier elements are switched to heating mode, thaws not only the walls of the recess 2 Touching surface of the ice, but also the water in the valve 20 so that this can open and air flow through the valve. So the ice body slides easily and quickly out of the recess 2 out.
  • While at the illustrated embodiments the moldings each having a single recess for generating a piece of ice is Naturally Also a modified embodiment of the invention conceivable, in the molded body has a plurality of recesses. The increased number However, the recesses requires increased dimensions of the molding required. The relationship from surface to volume decreases, and as a result also the cooling capacity, the with the help of on the surface attached to the molding Peltier elements is feasible. The for freezing water needed in the recesses Time is therefore at an icemaker, where several recesses on the molding is distributed in a two-dimensional arrangement, longer than at a shaped body a single recess, on the one hand because of the less favorable ratio of cooling power on the other hand, because of the increased average distance the recesses to the Peltier elements.
