  • PLATE TYPE ICE MAKER [75] Inventors: Charles G. Neumann, Palatin;
  • QATENTEDAPR 16 m4 SHEET 3 BF 4 BACKGROUND OF INVENTION Thereare known in the prior art two general types of ice makers. The first of these which produces what is known in the art as flake or chip ice rather than hard ice includes an auger or the like which scrapes ice crystals from a tubular freezing surface and feeds the resultant slush ice outwardly through a die or the like to form flake or chip ice. Alternatively, a cylindrical freezing chamber can be employed and scraper blades on the outside of the chamber remove the ice crystals. In all ice makers of this type this-chamber is vertical and of tubular or cylindrical shape.
  • the other type ice maker known in the art is a cube ice maker in which water in a container is subjected to the. action of a refrigerant. While some of the cube ice makers employ flat plate type evaporators, none of them produce ice on a continuous basis. That isto say, the freezing cycle is carried on until ice of the thickness of about one quarter to one. half inch is formedand is then interrupted. Following-interruption of the freezing cycle a harvest or defrost cycle is started. Thus, ice makers of this typedo not produce 'hard ice on a continuous basis. It is more. rugged than are auger type ice makers of the prior .art. It is less expensive to manufacture than auger type ice makers. It is more efficient than are cube type ice makers of the prior art. It does not require the alternate freeze and harvest cycles of cube type ice makers of the prior art.
  • One object of our-invention is to provide a plate type ice maker which overcomesthe defects of ice makers of the prior art.
  • Another object of 'ourinvention is to provide a plate type ice maker which produces chunks of hard ice on a continuous basis.
  • a further object of our invention is to provide a plate type ice maker which is more rugged than are auger type ice makers of the prior art.
  • a still further object of our invention is to provide a plate type ice maker which is less expensive to produce than are auger type ice makers of the prior art.
  • Yet another object of our invention is to provide a plate type ice maker which is more efficient than are cube type ice makers of the prior art.
  • Yet another object of our invention is to provide a plate type ice maker for producing pieces of hard ice without the necessity for alternate freeze and harvest cycles.
  • our invention contemplates the provision of a plate type ice maker in which a cutting edge at the entrance to an ice-forming passage moves over a plane BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a top plan view of one form of our plate type ice maker with parts removed and with other parts broken away.
  • FIG. 2 is a sectional view of the form of our plate type ice maker shown in FIG. 1 taken along the line 2-2 of FIG. 1. e
  • FIG. 3 is a sectional view of one of the ice rod fonning units of the form of ourplate type ice maker illus- I trated in FIGS. 1 and 2.
  • FIG. 4 is a fragmentary top plan view of an alternate embodiment of our plate type ice maker with parts removed.
  • FIG. 5 is a sectional view of the embodiment of our ice maker illustrated in FIG. 4.
  • FIG. 6 is a section view taken along a diametral chord of the-form of our ice maker shown in FIGS. 4 and 5 to illustrate the mode of operation thereof.
  • FIG. 7 is a fragmentary sectional view of a further form of our plate type ice maker.
  • FIG. 8v is a fragmentary sectional view of the form of our plate type ice maker shown in FIG. 7 and taken along thepath of movement of a cutter thereof to illustrate the operation thereof.
  • FIGS. 1 to 3 one form of our plate type ice maker indicated generally by the reference character 10, includes a motor 12, which provides the input to a gear box 14 having an output shaft 16.
  • a bracket 18 secured to a boss 20 on the gear box 14 is attached by means of a screw 22 or the like to an evaporator plate 24.
  • Refrigerant may be introduced into the channels 26 through an inlet 28.
  • a return outlet 30 permits the refrig'erant to pass back to the compressor (not shown).
  • Shaft 16 extends upwardly through a hollow hub 32 on the evaporator plate 24.
  • the arrangement is such that shaft 16 can rotate in the hub 32.
  • An annular freezer plate 34 is secured over the channels 26 by any suitable means known to the art. Refrigerant flowing through the channels 26 cools the plate 34 to permit ice crystals to form thereon in a manner to be described.
  • the form of our ice maker shown in FIGS. 1 to 3 includes three cube or ice piece-forming units indicated generally respectively by the reference characters 36, 38 and 40. Since all of the units 36, 38 and 40 are substantially identical we will describe only the unit 36 in detail.
  • the unit 36 includes a chute-forming member 42 provided with an ice chute 44 which, together with a roof or top member 46, forms a channel for the reception of slush ice.
  • the roof member may be secured to the channel-forming member 42 in any suitable manner. It includes a resilient tip portion 48 adapted to move to the broken line position illustrated in FIG. 3 in response to movement of a rod of ice up the passage.
  • the member 42 further is formed with a scraper edge 50 adapted to scrape ice crystals from the surface of the plate 34.
  • the leading edge of a rod of ice emerging from chute 44 passes under the tip 48, forcing it to the broken line position and ultimately engages a breaker surface 52 located in a plane forming an angle of less than 90 with the plane of the chute base and a piece of ice breaks off the rod.
  • the length L of the piece is approximately equal to the distance between surface 52 and the end of tip 48, as indicated in FIG. 3.
  • Member 42 is formed with a peripheral flange 54 adapted to receive screws 56 to secure the member 42 in an opening 58 in a support plate 60 threaded onto shaft 16 for rotation therewith.
  • a support plate 60 threaded onto shaft 16 for rotation therewith.
  • unit 36, 38 and 40 are radially staggered as indicated in FIG. 1. That is, unit 36 is radially positioned so that its edge 50 rides over the outermost portion of the surface of the plate 34. Unit 38 is so positioned that its edge 50 rides over the central portion of the annular plate 34. Unit 40 is furthest inboard so that its edge 50 rides over the innermost portion of the plate 34. If desired, we may provide some overlap between the edges 50 of the various units. We provide the surface of the .plate 34 with spaced radially extending grooves 64 for preventing a body of ice from moving along with the rotating support plate 60 when shaft 16 is driven.
  • a cover plate 66 on the plate 60 for rotation therewith. As chunks of ice are formed in the various units in a manner to be described they are discharged at locations above the plate 66 so as to be retained thereon. Any water running off the formed ice passes downwardly over the edge of the plate 66.
  • a surrounding wall 68 on the outer edge of plate 24 to provide a storage space for formed ice.
  • the entire assembly is provided with an insulating jacket 72.
  • An inlet pipe 70 permits water to be introduced into the .space over the freezer plate 34. Preferably, we maintain the water at a level indicated by the dot-dash line in FIG. 2.
  • a cover 74 is adapted to be removably secured over the top of the wall 68 by any suitable means such for example as by screws 76.
  • an alternate embodiment of our plate type ice maker indicated generally by the reference character 78 includes an evaporator plate 80 covered with a plate 82 providing the freezing surface.
  • the output shaft 84 of a gear box or the like passes upwardly through the central hollow hub of the plate 80 and is secured to an extruding head support 86 by means of a key 90 or the like the ends of which engage recesses in the hub 88 of the support plate 86.
  • a nut 92 threaded onto shaft 84 is adapted to position the support 86 on the shaft.
  • the support 86 carries a scraper blade 94 adapted to move over the surface 82 when the support member 86 is driven by shaft 84.
  • the blade 94 may include more than one scraping edge, such for example as a second edge at a location circumferentially spaced around hub 88 from the edge shown in the drawings.
  • the member 86 includes downwardly extending partitions 98 which, together with the upper surface of the scraping blade 94 provide extruding passages for the formation of ice. It will be seen that the space between the outer wall portion of support 86 and the hub 88 and between the top of head 96 and the cutting edge of blade 94 forms a plenum chamber just ahead of passages 100 in the direction of movement of the head 96. Ice being scraped from plate 82 collects in the plenum chamber and is partially dewatered in the course of its passage therethrough. Finally it is forced into passages 100 wherein it is extended to form hard ice.
  • Each of the passages 100 has an outlet 104 leading into a recess formed in the top of a drip ring 106 secured to shaft 84 for rotation therewith.
  • Each recess 108 is provided with a surface 110 on which a rod of ice emerging from the outlet 104 impinges.
  • FIG. 6 we have indicated water by the reference character 112, the thin film of ice on the surface of plate 82 by 114, slush ice in the plenum chamber by the reference character 116, the rod of ice by 118, and a broken off ice piece by 120. 1
  • the ice maker 122 includes a gear motor 124 having an output shaft 126.
  • a stationary housing 128 formed with a base 130 is secured to the gear motor housing by any suitable means such, for example, as by screws 132.
  • a refrigerant coil-forming member 134 supported on the base 130 carries a freezer plate 136 on the surface of which ice crystals form when water is supplied to the plate and when refrigerant flows in the coil-forming assembly 134.
  • the ice maker 122 includes a cutter disc 138 fonned with a hub 140 which is screwed onto or otherwise secured to the shaft 126 for rotation therewith.
  • a cover plate 142 secured to hub 140 in any suitable manner so as to be driven together with the cutter disc 138.
  • the salient feature of the form of our plate type ice maker illustrated in FIGS. 7 and 8 is a plurality of circumferentially extending radially spaced ribs or walls 144, 146, 148 and on the bottom of the cutter plate 138. Pairs of adjacent ribs 144 and 146, 146 and 148,
  • y and 148 and 150 provide confined passages 152, 154
  • Each assembly 158 is formed with an inclined passage 164 and with a base 166 secured to a boss 162 by any suitable means such, for example, as by screws 168.
  • An extension 170 on the trailing wall of the inclined passage 164 extends downwardly through the opening 160 and to a location at which a scraper edge 172 thereon cooperates with the portion of the freezer plate 136 associated with the channel 154 for example.
  • Each assembly 158 includes a spring finger 174 analogous to the finger 46 of the form of our invention illustrated in FIGS. 1 to 3.
  • the fingers 174 are provided with pivotal supports 176 which mount the fingers on the assemblies 158.
  • the action of the finger 174 compresses the slush ice until ultimately a rod of ice emerges from the upper end of the inclined passage 164.
  • the cut ice is contained within this track and is immediately forcedup the inclined plane formed by the bottom of chute 44. Owing to the fact that such a diametral track is formed, all ice is ultimately forced up the chute. In this manner, the slush ice is raised above the water level maintained in the freezing chamber. As more ice is forced up the chute, water is removed therefrom by elevating it above the water level. Ultimately the ice is forced against the spring tip 48 of the roof or top 46 of the chute 44. The pressure exerted by this closure forces additional water out of the ice until sufficient force is exerted by the rod of ice on the tip 48 to force it to the broken line position shown in FIG. 3. By this time, the ice emerging from the top of the chute is hard bar ice.
  • this bar of ice impinges on the surface 52 which is at an angle of less than to the bottom of the chute. Owing to the fact that the ice is brittle, it will fracture at the end of the tip 48 in its broken line position to form a chunk of ice. The thus-formed chunks of ice collect on top of the cover 66 so as to provide a sup ply of hard chunks of ice.
  • the scraper edges 172 of the respective units 158 scrape ice crystals off the surface of plate 136.
  • the walls or ribs 144, 146, 148 and 150 form confined channels extending 'circumferentially of the plate 136 and in line with the cutting edges 172 and the entries of the inclined passages 164 of the units 158. These passages ensure that ice scraped from the surface of plate 136 will enter the passages 164.
  • a rod of hard ice is formed in a manner similar to that in the operation of the form of our invention illustrated in FIGS. 1 to 3.
  • As a rod of ice emerges from the top of the inclined passage 164 it strikes the breaker surface so that pieces of hard ice break off' and are discharged outwardly through outlets 182 to the storage area in housing 128 above the cover 142.
  • Apparatus for forming hard pieces of ice including in combination, means forming an extended freezing surface, means forming an extruding passage having an entry and an exit, a gathering edge adjacent to said entry, and means mounting said passage forming means for movement relative to surface with said gathering edge adjacent to said surface to remove ice crystals from a film of ice on said surface and to deliver said crystals to said entry in the form of slush ice which enters said passage and emerges from said exit in the form of a hard rod of ice in response to relative movement between said passage forming means and said surface.
