Definitions

  • This invention relates to ice makers generally and in particular to an ice maker that comprises a sump that quickly slides from an operational position to a cleaning position.
  • Ice cube makers employing gridded freeze plates forming lattice-type cube molds, gravity water flow and ice harvest are well known and in extensive use. Such machines have received wide acceptance and are particularly desirable for commercial installations such as restaurants, bars, motels and various beverage retailers having a high and continuous demand for ice.
  • ice makers water is introduced at the top of a freeze grid which directs the water in a tortuous path toward a sump.
  • the frozen water collects on the freeze grid and is sensed by suitable means to defrost the grid whereupon the frozen product is discharged therefrom into an ice bin.
  • Control means associated with the ice maker are provided to control the operation of the device to insure a constant supply of frozen product.
  • a refrigeration system incorporating a compressor, condenser, evaporator and expansion valve is common.
  • the evaporator tubing is in direct physical connection with the freeze plate in order to freeze the water.
  • Water that falls from the freeze plate into a sump is recirculated from the sump across the freeze plate again until it freezes on the plate. Commonly water falls from the freeze plate back to the sump over and over until the charge of water sufficiently cools and begins to reach the freezing point.
  • One of the most desirable features of manufactured ice is that it be as clear as possible. Highly clear ice becomes increasingly difficult as operation of the machine continues until the machine is cleaned.
  • Tap water contaminants can generally be classified into three categories: suspended solids, dissolved minerals and metals, and chemicals.
  • Sand and dirt are examples of suspended solids and can be removed with mechanical filters. Chemicals are typically removed with carbon filtration. Removal of dissolved metals and minerals is more difficult and requires processes like reverse osmosis, distillation (water softening), or deionization. These processes are more expensive and difficult to implement, and ice machines generally do not include apparatus to remove any or certainly all minerals.
  • water softening just exchanges sodium ions for calcium and manganese, so the mineral problem is not effectively eliminated by water softening.
  • the minerals and metals general comprise sodium, potassium, calcium, magnesium, iron, copper, manganese, phosphorus, and zinc in amounts that vary with locale and type of water source.
  • Heavier scale deposits may require soaking in the acid solution, but manual scrubbing or wiping is also very effective and sometimes necessary to clean minerals and metals from the sump.
  • sumps are located under the evaporator and freeze plate, which make it difficult to access the interior of the sump to remove mineral build up and may require the use of tools to remove it.
  • the present invention comprises an ice maker having an upper section and a lower section.
  • the lower section comprises an ice storage portion
  • the upper section comprises a refrigeration compartment for housing at least a portion of a closed refrigeration circuit for making ice.
  • the upper section further houses an ice-making grid, a water pump and sump.
  • the lower section defines an ice opening from which ice can fall from the ice-making grid of the upper section into the lower section.
  • the sump is configured to be movable from a first position where the sump is positioned to catch unfrozen water falling from the ice-making grid to a second, cleaning position whereby the interior of the sump is more easily accessed.
  • FIG. 1 is an isometric view of an ice maker with its front cover removed according to an embodiment of the present invention
  • FIG. 2 is a side view an ice maker with its front cover removed and with its sump in an operating position according to an embodiment of the present invention
  • FIG. 3 is a side view an ice maker with its front cover removed and with its sump in an extended, cleaning position according to an embodiment of the present invention
  • FIG. 4 is a cross-sectional view of an ice maker with its front cover removed and with its sump in an operating position according to an embodiment of the present invention
  • FIG. 5 is a cross-sectional view of an ice maker with its front cover removed and with its sump in an extended, cleaning position according to an embodiment of the present invention.
  • FIG. 6 is an isometric view of a sump according to an embodiment of the present invention.
  • the preferred embodiment of the present invention comprises a sump which is moveable from a first, ice-making position to a second, extended, cleaning position.
  • the sump is held in either position by the friction of its own weight (and occasional the weight of the water within the sump) and requires no tools to move the sump between either position. It is protected from overextension and accidental removal by a back wall that will contact a portion of the upper cabinet and/or a front wall which will contact a portion of the upper cabinet thereby preventing the sump from being completely removed from the ice maker. Further, when in the extended position, the sump will block the hole through which ice falls when it is being harvested. This protects the ice and ice bin from contamination during the cleaning process. Referring to FIG.
  • a commercial type ice making machine 10 of the present invention is housed in a cabinet 12 which is located on top of a lower housing 14 that forms an ice receiving and storing compartment (ice bin 15) accessible through door 16 and an upper section 20 comprising a refrigeration compartment housing the compressor and condenser units of a closed refrigeration circuit.
  • the upper section 20 of the ice making machine 10 further includes evaporator tubing 18 (Figs. 4 and 5) attached to an ice making grid 21, which is located above a water pump 19 and sump 24.
  • the various compartments of the ice maker cabinet 12 are enclosed by suitable fixed and removable panels to provide temperature integrity and compartmental access, as will be understood by those in the art.
  • the closed refrigeration system housed in compartment 20 includes the refrigeration compressor and the air-cooled condenser.
  • the high pressure discharge side of the compressor is connected by a discharge line to the condenser.
  • Saturated liquid refrigerant flows from the condenser through liquid line having a filter/drier unit therein and is connected to a typical thermostatic expansion valve which meters refrigerant into the inlet 42 of the evaporator unit 21 in the freeze compartment.
  • the outlet 44 of the evaporator is connected by a suction line to a suction side of the compressor.
  • the refrigeration cycle is typical—the compressor supplies high pressure hot refrigerant gas to the condenser, where it is cooled to its saturation temperature and liquefied refrigerant flows to the evaporator 21 through the expansion valve.
  • the expanding vaporization of liquid refrigerant in the evaporator removes heat from the water on the evaporator 18 and freeze plate 21 thereby forming the ice cubes in the lattice molds thereon, and the gaseous refrigerant is returned to the compressor suction side to complete the refrigeration and freeze cycle.
  • the system also includes a hot gas by-pass line connected between the discharge line and the evaporator inlet 42 side downstream of expansion valve, and being controlled by solenoid valve to initiate an ice harvest cycle.
  • a hot gas by-pass line connected between the discharge line and the evaporator inlet 42 side downstream of expansion valve, and being controlled by solenoid valve to initiate an ice harvest cycle.
  • the sump 24 of the preferred embodiment comprises a generally rectangular box having an open top.
  • the sump 24 rests just above the lower cabinet 14 and is slidably movable between the positions of Figs. 2 and 3 (side view) and Figs. 4 and 5 (cross-section view).
  • the sump 24 is held in position by the friction of its own weight (and when full of water, the weight of the water within the sump 24).
  • a rear abutment surface 26 strikes a rear surface 28 of a rear wall 30 of the sump 24 and prevents the sump from being inserted too far within the upper housing 14 of the ice maker 10.
  • a front abutment surface 36 of the upper cabinet 14 strikes a rear abutment surface 38 of a front wall 40 of the sump 24.
  • the sump 24 may be moved to an extended position by sliding it outwardly toward a front of the ice maker 10. This done by manually pulling on a front wall 32 of the sump 24 until the sump 24 completely cover the ice hole 22.
  • the cleaning instructions for this machine do not include the requirement to remove ice from the bin prior to cleaning.
