9 Claims. (Cl. 62105) This invention relates to refrigerating apparatus and more particularly to a device which may be used for selectively dispensing either refrigerated Water, ice cubes or crushed ice.

t is an object of this invention to provide a simple and inexpensive arrangement for manufacturing and dispensing ice for use in chilling drinks and the like.

Another object of this invention is to provide a device for selectively dispensing either cold water, ice cubes or chipped ice.

Still another object of this invention is to utilize the ice cubes stored in the dispenser bin of an ice maker for prccooling water or the like.

Still another object of this invention is to provide a device in which the mere pressing of buttons will cause the device to selectively dispense the above mentioned items at a given station.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention is clearly shown.

in the drawings:

Figure l is a vertical elevational view with parts broken broken away showing the arrangement of the parts within the cabinet;

Figure 2 is a fragmentary front elevational view with parts broken away showing the ice cube metering device and the ice crushing device;

Figure 3 is a view looking down into the bottom portion of the ice cube hopper;

Figure 4 is a fragmentary elevational view showing the actuator mechanism for the ice cube metering device; and,

Figure 5 is a schematic circuit diagram showing the controls for the dispensing mechanisms.

Referring now to the drawing wherein a preferred ernbodiment of. the invention has been shown, reference numeral generally designates a cabinet of the type which is adapted to be mounted above the work surface in a modern kitchen, store counter or the like. Within the upper portion of the cabinet there is provided an automatic ice maker of the type more fully shown in copending applications Serial Number 355,061 filed May 14, 1953, new Patent No. 2,747,375, granted May 29, 1956, and Serial Number 278,928 filed March 29, 1952. Ice makers of this general type are now in extensive use and are known in the trade as Frigidaire ice makers. This ice maker is provided with a slanting plate 12 on which slabs of ice are frozen. After a slab of ice of a predetermined thickness has been frozen on the plate 12, the plate is allowed to warm up and the slab slides down the inclined plate onto an ice dissectoror grid 14 which cuts the slabs of ice into cubes which then are free to fall down into an ice cube storage bin 16. An evaporator serves to refrigerate the slanting ice freezing plate 12 in accordance with practice which is now well known in the trade. The evaporator 20 is supplied with liquid refrigerant from the refrigerant-liquefying unit generally 2,779,165 Patented an. 29,- 1957 designated by the reference numeral 22 and mounted beneath the freezing plate 12 as shown. The ice making equipment is designed to operate continuously until the ice cube storage bin 16 has been substantially filled, at which time the ice cubes will come in contact with the thermostat 24 which projects into the upper portion of the ice cube storage bin or hopper and shuts off the ice making equipment until the supply of ice drops below the thermostat 24. Since the ice making equipment and the controls therefor are of a construction which is now well known and which is fully shown and described in said above mentioned applications they need not be described in greater detail herein.

The lower end of the bin 16 is provided with an ice cube metering and dispensing device 30 and an ice crushing device 32 which are located side-by-side above a common delivery chute 42. The ice cube dispensing and metering device 30 consists of an oscillatable element 34 supported on a shaft 36. The element 34 has a V-shaped pocket 38 forming the bottom of the ice cube storage bin 16. Upon rotation of the shaft 36 from the solid line position in which it is shown in Figure 2 to its dotted line position, it will cause the ice cubes in the pocket 38 to be shoved past a flexible rubber gate element 40 into the delivery chute 42 from whence the ice cubes are delivered into a glass or other container (not shown) which may be set on the perforated drain board 44 located directly beneath the delivery chute 42. An arcuate extension 48 on the element 30 prevents the ice cubes in the bin from interfering with the return movement of the ice cube dispenser 30 at the completion of the ice cube dispensing operation.

The shaft 36 which operates the ice cube dispensing device 30 is adapted to be automatically operated by means of an electric solenoid 50 which has its armature connected to a lever or crank arm 52 secured to the shaft 36 as best shown in Figure 4. A spring 54 returns the ice cube dispenser into the full line position in which it is shown in Figure 2 when the solenoid is deenergized. Upon energization of the solenoid 50 the force of the spring 54 will be overcome and a given quantity of ice cubes will be dispensed. Upon deenergization of the solenoid 5%) the dispenser returns to the full line position so as to cause the V-shaped pocket 38 to be refilled.

In the event that the user wishes crushed ice rather than ice cubes, the ice crusher 32 can be placed into operation. The ice crusher 32 is driven by means of an electric motor 60 through a gear drive device 62. The ice crusher consists of a rotatable shaft element 64 which carries a plurality of blades 66 which pass between stationary blades such as the blades 68 so as to crush ice cubes from the bin before delivery into the chute 42.

A water chilling coil 70 is wrapped around the inner wall of the ice storage bin so as to cause the Water in the coil to be refrigerated by the ice cubes in the bin. Water enters the coil through an inlet 72 which is adapted to be connected to any suitable water supply such as the city water mains. The water leaves the coil 70 through the line 74 which leads to a solenoid operated valve 76. Upon energization of the solenoid valve 76 the water is discharged through a water dispensing nozzle 78 which is located within the delivery chute 42. in the event that the valve 76 is opened when no glass or other receptacle is in position to receive the water dispensed from the nozzle, the water will run down onto the perforated drain board 44 and into a drain receptacle or catch basin 45 from whence the water discharges into a conventional drain pipe 47 leading to a sewer or the like. The drain receptacle 45 is also adapted to catch any of the water from ice which may be meltedinthe ice bin.

In an ice maker of the type shown, it is standard prac- I tice to periodically drain sediment from the'water recepta- 3 she 79 through the siphon 'tube 81. This tube passes down'thro'ug'h the ice storage bin 16 as shown in Figure 1 and has an outlet 83 located behind the delivery chute 42 with the resultthat a single drain may be used for disposing of all of the waste water.

The ice crushing motor 69, the ice cube dispensing solenoid 50 and the water dispensing solenoid valve "i6 are adapted to be controlled by means of suitable push button switches Si), 82 and 84 respectively, located at the front of the cabinet in close proximity to the delivery chute. These but-tons bear suitable indicia (not shown} indicating their purpose.

By virtue of the above described arrangement it is obvious that the mere pushing of a selected button will cause the device to dispense either refrigerated water, cc cubes, or chipped ice depending upon which buttons the operator presses. Since the ice 1 ment is of the fully automatic type which mai continuous amount of ice cubes in the bin dd, it is obvibus that it is not necessary to provide an attendant to loci; after the supply of ice cubes. 'Whercas this invention can templates using an ice cube maker of the type disclosed in said c'opendingapplications, it is obvious that any type of automatic ice maker could be used for supplying ice cubes to the bin '16.

Figure 5 shows very schematically the electrical circuit for controlling the dispensing mechanism. As shown therein the control switches and the devices to be energized by the respective switches are connected in parallel to apower source.

While the invention contemplates selectively'dispensing either cold water, whole ice blocks or chipped ice it should be apparent, by virtue of the water, whole ice blocks and crushed icebeing dispensed through the single delivery chute 42 and of the parallel connections of the various switches in the. electrical circuit, that a combination of crushed ice .and ice blocks or either ice blocks and cold water and particularly crushed ice and cold water can, if desired,'besimultaneously dispensed from the apparatus. To accomplish this the user of the apparatus may depress the button of two of the push button switches 80, 82 and 84 at one and the same time such, for example, as buttons 84 and 82 when cool water and ice blocks are desired to be dispensed and caught in a receptacle to be placed on a dinner table and/ or buttons 84 and 80 when cool water'and crushed ice aredesired to be dispensed and'caught in a glass or receptacle.
