DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the drawings. The embodiments are described below to explain the present invention by referring to the figures.
FIG. 2 is a side sectional elevation illustrating the interior of a refrigerator according to an embodiment of the present invention, and FIG. 3 is a front sectional view illustrating a main component of the refrigerator of FIG. 2.
In FIGS. 2 and 3, a refrigerator according to an embodiment of the present invention includes a cabinet 11 defining at least one storage chamber 10 therein, and at least one door 12 hinged to a front side of the cabinet to open or close the storage chamber 10. The cabinet 11 and the door 12 are made of a thermally insulated wall to shield heat transfer from the outside.
The storage chamber 10 includes a plurality of shelves 13 to locate food containers and the like thereon, and having a plurality of drawers 14 to store vegetables, fruits, and the like therein. The storage chamber 10 includes an evaporator 15 at a rear side of an upper portion thereof, as a component of a typical cooling cycle to cool the storage chamber 10. The door 12 is provided, at an inside surface thereof facing the storage chamber 10, and includes a plurality of door guards 16 to place beverage cans or bottles therein.
A machinery chamber 17 is formed at a rear side of a lower portion of the cabinet 11 to operate the refrigerator, and includes a compressor 18 as a component of the typical cooling cycle necessary to operate the refrigerator.
The door 12 is provided at an outer surface thereof with a dispenser 20, which allows ice to be easily dispensed without opening the door 12. An ice supplying device 30 is provided at an upper portion of the storage chamber 10, and supplies the ice to the dispenser 30.
The ice chamber 30 includes an ice tray 31 to freeze water into ice having a predetermined size and shape, a water supplying pipe 32 to supply water to the ice tray 31, an ice storing box 33 located below the ice tray 31 to store ice cubes frozen in the ice tray 31, a spiral-shaped feeding spring 34 to feed the ice from the ice storing box 33 to the dispenser 20 of the door 12, and a motor 35 to drive the feeding spring 34. The front end of the ice storing box 33 is opened downwardly to form an ice exit 33 a, through which the ice is supplied to the dispenser 20.
The dispenser 20 includes an ice cube dispensing part 21 to allow the ice cubes supplied from the ice supplying device 30 to be directly dispensed, and a shaved ice dispensing part 22 to allow shaved ice to be dispensed after pulverizing the ice cubes supplied from the ice supplying device 30 to the shaved ice. The ice cube dispensing part 21 and the shaved ice dispensing part 22 are operating levers, which are subjected to an operation for drawing out the ice.
An ice feeding passageway 23 is formed in the door 12 from a portion below the ice exit 33 a of the ice supplying device 30, and branched into the ice cube dispensing part 21 and the shaved ice dispensing part 22 therein. The ice feeding passageway 23 consists of an ice cube passageway 23 a connected to the ice cube dispensing part 21, and a shaved ice passageway 23 b connected to the shaved ice dispensing part 22.
A passageway-changing member 24 is positioned at a branch point in the ice feeding passageway 23 to selectively guide the ice supplied from the ice supplying device 30 to the ice cube passageway 23 a or to the shaved ice passageway 23 b. The passageway-changing member 24 is hingably positioned in the ice feeding passageway 23 with one side thereof acting as a rotational shaft. When the passageway-changing member 24 is positioned at the location “a” of FIG. 3, the ice cube passageway 23 a is closed while the shaved ice passageway 23 b is opened, and when the passageway-changing member 24 is positioned at the location “b” of FIG. 3, the ice cube passageway 23 a is opened while the shaved ice passageway 23 b is closed. In FIG. 4, a driving shaft of a motor 25 for driving the passageway-changing member 24 is connected to one end of the rotational shaft of the passageway-changing member 24.
An ice shaver 40 is positioned on the shaved ice passageway 23 b to pulverize the ice cubes supplied from the ice supplying device 30 into shaved ice.
Referring to FIGS. 4 and 5, the construction of the ice shaver 40 will now be described as follows. The ice shaver 40 is embedded in the door 12, and includes a cup-shaped housing 41 having a convex bottom, a rotor 42 rotatably positioned within the housing 41, and a motor 43 to drive the rotor 42.
The housing 41 is opened at an upper portion thereof such that the rotor 42 can be inserted thereto, and provided at the center thereof with a cylindrical rotational shaft 41 b extending from the bottom 41 a of the housing 41. A slit 41 c is radially formed on the bottom 41 a of the housing 41 to discharge the pulverized shaved ice, and is connected at one side thereof to a cutter 41 d for pulverizing the ice. A guide 41 e having a predetermined length is formed below the slit 41 c to guide the shaved ice provided into the slit 41 c to the shaved ice dispensing part 22.
The rotor 42 is positioned in the housing 41 to be rotated therein. The rotor 42 includes a central portion 42 a having a bore formed therein to allow the rotational shaft 41 b of the housing 41 to be inserted into the bore, a cylindrical surrounding portion 42 b spaced a predetermined distance from the central portion 42 a, and a spiral-shaped intermediate plate 42 c provided between the central portion 42 a and the surrounding portion 42 b. When the rotor 42 is rotated in the direction of the arrow, the intermediate plate 42 c serves to feed the ice cubes toward the cutter 41 d while compressing the ice cubes against the bottom 41 a of the housing 41. As a result, the ice cubes is pulverized into the shaved ice by the cutter 41 d fixed to the bottom 41 a of the housing 41, and is then discharged to the slit 41 c as the pulverized ice.
A predetermined gear 42 d is formed around an outer peripheral surface at an upper portion of the surrounding portion 42 b of the rotor 42, and is engaged with a pinion 44 rotated by a driving motor 43.
Operation for obtaining the ice from the refrigerator according to one embodiment of the present invention will now be described.
When a user wants to obtain ice cubes from the dispenser 20 of the refrigerator, the ice cube dispensing part 21 is pushed by means of a container, such as a cup, and then the motor 35 of the ice supplying device 35 is operated to allow the ice cubes to be discharged from the ice storing box 33 through the ice exit 33 a. The ice cubes discharged through the ice exit 33 a is dropped into the ice feeding passageway 23. The passageway-changing member 24 provided at the branch point in the ice feeding passageway 23 is converted to the location b of FIG. 3, and the ice cubes discharged through the ice exit 33 a passes through the ice cube passageway 23 a, and is then supplied to the dispenser 20.
When the user wants to obtain shaved ice from the dispenser 20 of the refrigerator, the shaved ice dispensing part 22 is operated. Similar to the case of obtaining the ice cubes from the refrigerator, the motor 35 of the ice supplying device 35 is operated to allow the ice cubes to be discharged from the ice storing box 33 through the ice exit 33 a. The passageway-changing member 24 is driven by the motor 25, and is converted to the location a of FIG. 3, where the ice cube passageway 33 a is closed while the shaved ice passageway 23 b is opened, thereby allowing the ice to be fed to the ice shaver 40. In the ice shaver 40, the rotor 42 driven by the motor 43 moves the ice cubes dropped into the rotor 42 downward. Then, the ice cubes moved downward is pulverized into shaved ice by means of the cutter 41 d while being rotated on the bottom 41 a of the housing 41 in a state of being compressed by the rotor 42. The shaved ice is discharged to the slit 41 c, and is then supplied to the dispenser 20.
As apparent from above description, according to the present invention, there is an advantageous effect in that, as the refrigerator is provided with the ice shaver for supplying shaved ice, and the ice distributing structure for dispensing the ice, various shapes of ice can be supplied according to needs of the user.
Although a few embodiments of the invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
