The embodiments of the present invention are described below to explain the present invention by referring to the figures.
FIG. 2 is a perspective view illustrating the appearance of a refrigerator according to an embodiment of the present invention. FIG. 3 is a sectional view taken along line III-III′ of FIG. 2. FIG. 4 is a perspective view illustrating only the dispenser of FIG. 2, wherein a cover is disassembled from a door.
As illustrated in FIGS. 2 and 3, the refrigerator, according to an embodiment of the present invention, comprises a main body 10 which includes a storage chamber 11 for storing food, and a pair of doors 20 that are pivotably installed to the main body 10 so as to open and close the storage chamber 11. The main body 10 comprises an outer cabinet 10a forming an outer surface thereof, and an inner cabinet 10b spaced apart from the outer cabinet 10a at a predetermined interval and forming the storage chamber 11 thereinside. A heat insulating material 10c to prevent cold air from being lost is formed between the outer cabinet 10a and the inner cabinet 10b. 
The storage chamber 11 is divided left and right into a refrigerating chamber 11a and a freezing chamber 11b by an intermediate partition 12, wherein the refrigerating chamber 11a cools and stores food on the right side, and the freezing chamber 11b freezes and stores food on the left side. The storage chamber 11 is provided with a cold air generating chamber 15, which generates cold air to be supplied to the storage chamber 11, at the rear thereof. The cold air generating chamber 15 comprises an evaporator 16, which exchanges heat with surrounding air and thereby generating cold air. A blowing fan 17 for supplying the generated cold air to the storage chamber 11 is installed around the evaporator 16.
Further, the door 20 comprises a dispenser 30 on the front surface thereof such that a user can extract a desired object such as water or ice without opening the door 20. Although not illustrated in the figure, the main body 10 is provided with a water vessel in which water is stored, and a water supply pipe that guides the water from the water vessel to the dispenser 30. The water supply pipe is provided, at one end thereof, with a water extraction port 18, through which the cold water stored in the water vessel is extracted.
Further, the freezing chamber 11b is provided therein with an ice supply mechanism 25 for supplying ice to the dispenser 30. The ice supply mechanism 25 comprises an ice making unit 26 which makes ice cubes, an ice storage vessel 27 that is disposed below the ice making unit 26 and stores the ice cubes made by the ice making unit 26, a transfer unit 28 transfers the ice cubes stored in the ice storage vessel 27, and a cracking unit 29 cracks the ice cubes transferred by the transfer unit 28 and makes chips of ice. In this manner, in order to extract the ice cubes made by the ice supply mechanism 25 to the dispenser 30, the door 20 comprises an ice extraction port 21 to extract the ice cubes.
As illustrated in FIGS. 2, 3 and 4, the dispenser 30 according to an embodiment of the present invention, comprises a case 31 that forms an extraction section 31a which is a space for extracting a desired object such as water or ice, a push button 32 (i.e., key unit) which is installed on a rear surface of the case 31 and operates a device which extracts the desired object such as water or ice, and a cover 33 which is pivotably installed to the case 31 so as to be able to open and close the extraction section 31a. 
The case 31 comprises the water and ice extraction ports 18 and 21, through which the desired object is extracted, at the upper rear thereof, and a display panel 34, which displays the operated state of the dispenser, at the upper front thereof. Further, the case 31 comprises a water tray 35 to collect a part of the desired object which is extracted through the water and ice extraction ports 18 and 21 but is not contained in a container.
The cover 33 is made of a flat plate, for example, such that the front surface of the cover 33 forms the same plane as the front surface of the door 20 when the extraction section 31a is closed. The cover 33 comprises an opening 33a at a central portion thereof, formed by cutting out part thereof so as to allow a container such as a cup to pass through the opening 33a. 
The cover 33 comprises hinge shafts 33b at a lower portion thereof, such that the cover 33 is pivotably coupled with the case 31. Further, the cover 33 comprises a hooking unit 36 at an upper portion thereof, such that the cover 33 is coupled with and decoupled from the door 20 whenever the user pushes the cover 33.
The hooking unit 36 comprises hooks 36a installed to the cover 33, and hooking recesses 36b installed to the case 31 and receiving and separating the hooks 36a. This hooking unit 36 is broadly used, and so a description thereof will be omitted.
In this manner, due to the cover 33 opening and closing the extraction section 31a, the front appearance of the refrigerator is more beautiful, and the refrigerator prevents foreign materials such as dust from entering the extraction ports 18 and 21 through which the desired objects are extracted.
The dispenser 30 of the refrigerator according to an embodiment of the present invention comprises a lever 40 such that the user pushes the push button 32 to be able to extract the desired object such as water or ice although the cover 33 does not open the extraction section 31a. 
The lever 40 is adapted to open and close the extraction section 31a together with the cover 33, as well as to open and close the opening 33a of the cover 33. The lever 40 comprises hinge shafts 41 on opposite side of a lower end thereof, so that the lever 40 can be pivoted backwards to push the push button 32 when the user grasps the container such as a cup to push the lever 40. Elastic springs 42 are fitted around the hinge shafts 41 such that the lever 40 returns to an original state when the user releases force applied to the lever 40.
The lever 40 comprises a stepped stopper 43 at an upper end thereof. The elastic force of the elastic springs 42 is exerted in a direction where the lever 40 is supported on the cover 33. Therefore, the lever 40 can be pivoted only toward the extraction section 31a, and is pressed in the direction supported on the cover 33. When the force applied to the lever 40 is removed, the lever 40 is unified with the cover 33 by means of the elastic force of the elastic springs 42.
FIGS. 5 and 6 illustrate the operation of a dispenser according to an embodiment of the present invention.
When the user wants to extract a desired object using a container 50 that is smaller than the opening 33a, the user pushes the lever 40 in the state in which the cover 33 closes the extraction section 31a as illustrated in FIG. 5. Therefore, the lever 40 is rotated about the hinge shafts 41 toward the extraction section 31a. Thus, the upper end of the lever 40 rotated about the hinge shafts 41 pushes the push button 32, and then the desired object such as water or ice is extracted and contained into the container 50.
After the desired object is contained into the container 50 at a desired amount, the user removes the force applied to the lever 40. Thus, the lever 40 returns to its original state by rotating about the hinge shafts 41 by means of the elastic force of the elastic springs 42, thereby closing the opening 33a. 
According to an embodiment of the present invention, when the user wants to extract the desired object using the container 50 that is larger than the opening 33a, the container 50 cannot pass through the opening 33a of the cover 33.
At this time, when the user pushes the upper portion of the cover 33, the hooks 36a of the hooking unit 36 escape from the hooking recesses 36b as illustrated in FIG. 6, and the cover 33 is rotated about the hinge shafts 33b, thereby opening the extraction section 31a. 
In this manner, when the cover 33 opens the extraction section 31a, and thus the rear surface of the cover 33 is in an approximately horizontal state, the cover 33 can be used as a support table on which the container such as a cup is placed.
When the user directly pushes the push button 32 using the container 50 in the state in which the cover 33 has opened the extraction section 31a, the desired object is extracted through the extraction port 18 or 21, and is contained into the container 50.
After the user extracts the desired object, the user fixes the upper portion of the cover 33 to the case 31 using the hooking unit 36 installed to the upper portion of the cover 33, thereby closing the extraction section 31a. Thus, the front appearance of the refrigerator is beautifully maintained, and the refrigerator prevents foreign materials such as dust from entering the extraction ports 18 and 21 through which the desired objects are extracted.
As described in detail above, according to the dispenser and the refrigerator having the same, various switches installed to the extraction section can be covered, and thus the front appearance of the refrigerator is beautifully maintained.
Further, according to an embodiment of the present invention, the dispenser prevents the foreign materials such as dust from entering the extraction ports through which the desired objects are extracted.
Although a few embodiments of the present 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.
