ICE CUBE MAKER Filed May 6. 1953 INVENTOR. ROMEO 5. DENzER BM a W ICE CUBE MAKER Romeo S. Denzer, La Crosse, Wis.
Application May 6, 1953, Serial No. 353,291
Claims. (Cl. 62-107) This invention relates to apparatus for automatically making ice cubes. More specifically, it relates to an ice cube maker which freezes a tray of cubes, releases said cubes for discharge to a storage bin and automatically repeats the freezing and releasing cycles.
It is an object of this invention to provide apparatus for freezing ice cubes in inverted cups and for periodically applying heat to release said cubcs for movement by gravity to a storage bin.
It is another object of this invention to release the ice cubes by conducting hot refrigerant gas to the evaporator and by causing make up water to flow over the evaporator before falling into the reservoir. The heat from the make up water contributes to the release of the frozen cubes and at the same time the make up water is precooled so that it does not substantially increase the temperature of the water in the reservoir.
It is another object of this invention to provide a main reservoir and a secondary reservoir for maintaining a substantially constant level in the main reservoir.
Other objects and advantages of the invention Will appear as the specification proceeds to describe the invention with reference to the accompanying drawings in which:
Fig. 1 is a cross-sectional view, partly diagrammatic, showing the interior construction of my improved ice cube maker;
Fig. 2 is a cross-sectional view taken on line 2-2 of Pig. 1.
Fig. 3 is an enlarged plan view of a spray disc.
Fig. 4 is an end view of the spray disc.
Referring now to the drawings the cabinet is designated generally by numeral and is divided by partition 12 'into a freezer space 14 and an equipment space 16. The
walls of the cabinet 10 are insulated to reduce the transmission of heat therethrough.
An evaporator 18 has a plurality of inverted cups 20. Water is sprayed into the cups 20 by rotating discs 22 which are mounted on shaft 24. A motor 26 is mounted on partition 12 and drives pulley 28. A pulley 30 is mounted on shaft 24 and a belt 32 engages pulleys 28 and 30 to transmit the driving force from motor 26 to shaft 24. Discs 22 extend below the level of water in a reservoir 34. An overflow pipe 36 prevents the water in tank 34 from rising beyond a predetermined point. A partition 38 provides an auxiliary reservoir 40 which receives spray water at the start of a freezing cycle and feeds said water to the main reservoir 34 as freezing progresses. Partition 38 has an opening 42 which permits water to fiow from auxiliary reservoir 40 to reservoir 34 at a predetermined rate. The opening 42 is sized slightly larger than required to supply the water at the exact rate at which it is frozen because if the fiow to the main reservoir is greater than necessary the level in the main reservoir will rise causing more water to be sprayed back into the auxiliary reservoir 40.
A refrigeration compressor 56 is mounted in the equipment space 16 and has a discharge pipe 58 for conducting refrigerant to a condenser 60 which is cooled by air moved by a fan 62 driven by a motor 64. Pipe 66 conducts refrigerant from condenser 60 to a capillary tube 68, and pipe 70 conducts refrigerant from capillary tube 68 to evaporator 18. The cups 20 extend into a chamber 72 which conducts the refrigerant into intimate contact with all of the cups 20 of the evaporator 18 and a pipe 74 conducts the refrigerant from chamber 72 to the compressor 56.
A pipe 76 conducts refrigerant from pipe 58 to a solenoid valve 78 and a pipe 80 connects solenoid valve 78 to pipe 70. When the solenoid valve 78 is opened hot gaseous refrigerant from pipe 58 bypasses condenser 60 and capillary tube 68 and flows directly as a gas through pipe 70 to evaporator 18 to heat the evaporator and release the cubes as will be more fully described.
Water is supplied from any source 82 and flow is controlled by a solenoid valve 84. A pipe 86 conducts the water from solenoid valve 84 to a spray tree 88 from which the water flows and runs down over the top of the evaporator 18 finally dropping into the reservoir 34. v
The operation of the cube maker will now be described. When the freezing of cubes is taking place, refrigerant fiows through condenser 60, pipe 66, capillary tube 68, pipe 70 to evaporator 18. Refrigerant gas fiows from evaporator 18 through pipe 74 to compressor 56. During the freezing cycle, rotating discs 22 supply a fine spray of water to the cups 20. A timer or a thermostat on the evaporator not shown, will signal the completion of a freezing cycle and energize solenoid valves 78 and 84 to open these valves. When valve 78 is opened, hot refrigerant gas is conducted directly to the evaporator, and the cups 20 are heated by the gas to release the cubes. When valve 84 is open, water fiows from spray tree 88 and over the top surface of evaporator 18 before dropping into reservoir 34. This water gives up some of its heat to the evaporator to release the cubes, and the water is precooled before entering the reservoir 34. The timer or thermostat closes valve 84 after a predetermined length of time which is sufiicient to add enough water to make up for that frozen and to permit some water to be discharged through overflow pipe 36. The timer or thermostat also closes solenoid valve 78 after a predetermined length of time sufficient for all the cubes to be released from the cups 20.
When the water valve 84 is open the level of water in tank 34 rises and discs 22 spray a larger volume of water with the result that auxiliary reservoir 40 is filled. As water from reservoir 34 is frozen to the cups 20 the level of water in reservoir 34 is maintained by the fiow of water from auxiliary reservoir 40 through orifice 42, and the spray from discs 22 is maintained Constant throughout the freezing cycle.
It should be understood that although I prefer to use a timer to nitiate the freezing and releasing cycles, other means such as pressure switches or thermostats can be used as is well known to those skilled in the art.
Although I have described specifically the preferred embodiment of my invention, various changes are possible without departing from the scope of the invention, and I desire to be limited only by the claims.
