Technical Field

[1] The present invention relates to a dispenser and a refrigerator having the same, and particularly, to a dispenser capable of easily catching water and a refrigerator having the same. Background Art

[2] In general, a refrigerator is an apparatus for storing foods or the like in a cooling chamber configured therein under a lower temperature. Such refrigerator includes a refrigerator main body having a cooling chamber therein, a door for opening/closing the cooling chamber, and a refrigerating cycle for supplying cold air to the cooling chamber.

[3] The refrigerating cycle is typically implemented as a vapor compression refrigerating cycle including a compressor for compressing a refrigerant, a condenser for condensing the compressed refrigerant, an expander for expanding the condensed refrigerant, and an evaporator for adsorbing and evaporating peripheral latent heat.

[4] In addition, the refrigerator may be provided with a dispenser for supplying purified water to a user.

[5] When a user puts a cup on the dispenser and operates a manipulation lever, water supplied via a water supply tube is dropped in the cup through a nozzle formed in the dispenser. Accordingly, the user can get water from the dispenser.

[6] However, in the related art refrigerator, since the nozzle is fixed to a housing of the dispenser, it may be impossible or difficult to adjust a direction to supply water via the nozzle.

[7] Furthermore, it is difficult to catch a relatively much amount of water in a container greater than an inner space of the dispenser housing, which causes a user's inconvenience. Disclosure of Invention

Mode for the Invention

[42] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

[43] Hereinafter, a refrigerator hving a dispenser according to the present invention will be explained.

[44] As shown in FIGS. 1 to 3, a refrigerant having a dispenser according to the present invention may include a refrigerator main body 110 having a cooling chamber therein, doors 125 and 135 for opening/closing the cooling chamber, and a dispenser 150 disposed at the door 125. Here, the cooling chamber totally indicates a refrigerating chamber and a freezing chamber, and the refrigerator main body 110 may be formed to only have one of the freezing chamber and the refrigerating chamber. Also, the dispenser 150 may be configured at the refrigerating chamber door. This embodiment of the present invention is implemented such that the refrigerator main body 110 has a freezing chamber 120 and a refrigerating chamber 130 disposed respectively at right and left sides thereof. However, the freezing chamber 120 and the refrigerating chamber 130 may be disposed up and down.

[45] The freezing chamber 120 and the refrigerating chamber 130 are formed in the refrigerator main body 110. A freezing chamber door 125 and a refrigerating chamber door 135 are disposed at front surfaces of the freezing chamber 120 and the refrigerating chamber 130, respectively, to open/close the corresponding chambers 120 and 130. A home bar 137 for keeping foods or the like or taking such food out there without opening the refrigerating chamber door 135 may be disposed at the refrigerating chamber door 135.

[46] In the meantime, the dispenser 150 for dispensing water without opening the freezing chamber door 125 may be disposed at the freezing chamber door 125. The dispenser 150 may include a dispenser housing 151 having an accommodating space 152 therein, and a water supply unit 180 disposed inside the accommodating space 152 and implemented to adjust one of its height and direction. Here, the dispenser housing 151 may further be provided with an ice supply unit (not shown) for supplying ices.

[47] A penetrated portion 127 is formed through a front surface of the freezing chamber door 125 in a thickness direction, and thus the dispenser housing 151 is inserted in the penetrated portion 127 from a front side of the freezing chamber door 125.

[48] The dispenser housing 151 has the accommodating space 152 for accommodating a small container Cl, such as a cup. A manipulation lever 161 operated by being touched or pressed such that water can be dispensed may be disposed in the accommodating space 152. An input unit 155 for inputting a manipulating signal and a display 156 for outputting certain visual information may be disposed at the front surface of the dispenser housing 151. Here, the input unit 155 may be implemented as a press button, or be implemented to input a signal in a touching manner. Here, the water supply may also be executed by the manipulation of the input unit 155.

[49] The manipulation lever 161 may be installed at a rear wall of the dispenser housing

151. Here, the manipulation lever 161 may include an operation portion 162 to which an external force is applied, a connection portion 164 connected to the operation portion 162, and an axis 166 for rotatably supporting the connection portion 164. Here, the operation portion 162 or the connection portion 164 may be connected to a switch or sensor (not shown) for generating a signal and the switch or sensor is connected to a controller (not shown), such that water can be dispensed upon a signal input.

[50] The water supply unit 180 may be formed at an upper portion of the accommodating space 152.

[51] The water supply unit 180 may include a water supply tube 181 through which water is supplied, a flexible tube 185 having one end connected to the water supply tube 181, and a nozzle 191 connected to another end of the flexible tube 185. A filter (not shown) may be disposed in the water supply tube 181. Also, the water supply tube 181 may pass through the refrigerating chamber 130 so as to supply cold water.

[52] Here, the flexible tube 185 may be formed of a flexible material, and also be formed of a material or in a structure being flexibly transformed. In this embodiment, the flexible tube 181 is implemented in a shape of wrinkled pipe, namely, having a structure of being flexibly transformed.

[53] The nozzle 191 may be formed to have an extended size as compared to the flexible tube 185. A nozzle coupling portion 175 to which the nozzle 191 is separably coupled may be formed on a ceiling of the dispenser housing 151.

[54] The nozzle coupling portion 175 may be formed to correspond to the shape of the nozzle 191 such that one region of the nozzle 191 can be accommodated therein. An engaging portion 195 to which the nozzle 191 is fixed may be formed at a contact region between the nozzle 191 and the nozzle coupling portion 175. The engaging portion 195 may include a protrusion 196 protruded from one of mutual contact surfaces between the nozzle 191 and the nozzle coupling portion 175 to another surface thereof, and a protrusion receiving portion 197 formed in the another surface to receive the protrusion 196 therein. Here, at least one of the protrusion 196 and the protrusion receiving portion 197 may be formed to be elastically transformed upon the coupling therebetween. This embodiment is implemented such that the protrusion 196 is protruded from an outer surface of the nozzle 191 and the protrusion receiving portion 197 is recessed in the nozzle coupling portion 175.

[55] On the other hand, a flexible tube receiving portion 171 for receiving the flexible tube 185 may be formed at an upper area of the dispenser housing 151. The flexible tube 185 may be implemented such that the nozzle 191 is separated from the nozzle coupling portion 175 to have a length long enough to be movable within a certain range. That is, the flexible tube 185 has a length longer than a distance between the water supply tube 181 and the nozzle coupling portion 175. Accordingly, when the nozzle 191 is spaced apart from the nozzle coupling portion 175 by being separated therefrom, the flexible tube 185 is extended as long as a distance that the nozzle 191 is spaced apart from the nozzle coupling portion 175. When the nozzle 191 is coupled to the nozzle coupling portion 175, the flexible tube 185 is received within the flexible tube receiving portion 171 via the nozzle coupling portion 175.

[56] With such configuration, when desiring to catch water in a relatively small container

Cl, such as a cup, the container Cl is put in the accommodating space 152 of the dispenser housing 151 and the manipulation lever 161 is then manipulated, so as to catch water. On the other hand, when desiring to catch water in a container C2 relatively greater than the accommodating space 152, the nozzle 191 is pulled downwardly to thusly be separated from the nozzle coupling portion 175, and then the separated nozzle 191 is appropriately located above the container C2. Here, the flexible tube 185 is extended as long as a distance that the nozzle 191 is moved from the nozzle coupling portion 175. Afterwards, upon manipulating the manipulation lever 161 or the input unit 155, water can be dispensed via the nozzle 191.

[57] Hereinafter, a refrigerator having a dispenser according to a second embodiment of the present invention will be described with reference to FIGS. 4 and 5.

[58] The same reference numerals will be equally used for the same and like portions to the aforementioned and illustrated configuration, and the description thereof will be omitted.

[59] As shown in FIGS. 4 and 5, a refrigerator with a dispenser according to the present invention may include a refrigerator main body 110 having a cooling chamber therein, a door 125 for opening/closing the cooling chamber, and a dispenser 150 disposed at the door 125.

[60] The dispenser 150 may include a dispenser housing 151 having an accommodating space 152 therein, and a water supply unit 180 disposed inside the accommodating space 152 and implemented to adjust one of its height and direction.

[61] The water supply unit 180 may include a water supply tube 181 through which water is supplied, a flexible tube 185 having one end connected to the water supply tube 181, and a nozzle 191 connected to another end of the flexible tube 185.

[62] A manipulation lever 161 operated for allowing water to be dispensed is disposed inside the dispenser housing 151. The nozzle 191 is coupled to a ceiling of the accommodating space 152 of the dispenser housing 151, and a flexible tube receiving portion 171 for receiving the flexible tube 185 therein is formed at an upper area of the dispenser housing 151.

[63] A water supply tube 181 for supplying water is disposed in the flexible tube receiving portion 171. The water supply tube 181 is connected to one end of the flexible tube 185 formed to have a length longer than a distance between the water supply tube 181 and the nozzle coupling portion 175.

[64] On the other hand, a winding unit 210 on which the flexible tube 185 is wound is disposed in the flexible tube receiving portion 171, so as to facilitate an extension and retraction of the flexible tube 185 with such long length.

[65] The winding unit 210 may include a sheave 211 having a circumferential surface on which the flexible tube 185 is wound, and supporting bars 213 for rotatably supporting the sheave 211. The sheave 211 may be formed to have a length as long as being wound by the flexible tube 185 plural times. Both ends of the sheave 211 are rotatably supported by the supporting bars 213. The flexible tube 185 is contacted and fixed at the middle of the sheave 211 and wound thereon plural times. That is, the flexible tube 185 is configured such that, initially, part of the water supply tube side section 186a is not wound on the sheave 211 and part of the nozzle side section 186b is wound on the circumference of the sheave 211. Accordingly, upon the separation or movement of the nozzle 191, the section 186b wound on the sheave 211 is unrolled to be extended and simultaneously the section 186a not wound on the sheave 211 is then wound on the circumference of the sheave 211. On the other hand, upon coupling the nozzle 191 to the nozzle coupling portion 175, the nozzle side section 186b is wound on the circumference of the sheave 211, and the water supply tube side section 186a wound on the sheave 211 is then unrolled.

[66] The winding unit 210 may further include an elastic member 215 having an elastic force applied to rotate the sheave 211 to its original position, which makes it easy to retract the flexible tube 185 extended to the exterior due to the movement of the nozzle 191.

[67] The elastic member 215 may be configured as a spring, in more detail, as a coil spring or torsion spring. One end of the elastic member 215 may be fixed to the sheave 211 and the other end thereof may be fixed to the supporting bar 213. As a result, the elastic member 215 accumulates an elastic force by a rotational force of the sheave 211 rotated upon extending the flexible tube 185. Also, upon retracting the flexible tube 185, the sheave 211 is rotated by the accumulated elastic force, so as to facilitate the rolling of the flexible tube 185.

[68] With such configuration, when desiring to catch water in a relatively small container

Cl, such as a cup, the container Cl is put in the accommodating space 152 of the dispenser housing 151, and the manipulation lever 161 is then manipulated, thus to receive water in the container Cl. On the other hand, when desiring to catch water in a container C2 greater than the accommodating space 152, the nozzle 191 is pulled downwardly to be separated from the nozzle coupling portion 175. When the separated nozzle 191 is further pulled, the flexible tube 185 wound on the circumference of the sheave 211 is unrolled to be extended. Here, the sheave 211 is rotated and the elastic member 215 accumulates an elastic force by the rotational force of the sheave 211.

[69] Then, after the nozzle 191 is appropriately located above the container C2, when the manipulation lever 161 or the input unit 155 is operated, water is dispensed via the nozzle 191.

[70] Upon the completion of water reception, the nozzle 191 is slowly moved to the nozzle coupling portion 175 to thereafter be coupled back to the nozzle coupling portion 175. Here, the sheave 211 is rotated opposite to being extended due to the elastic force of the elastic member 215, and accordingly, the thusly received flexible tube 185 is easily wound on the circumference of the sheave 211.

[71] Hereinafter, a refrigerator with a dispenser according to a third embodiment of the present invention will be described with reference to FIGS. 6 and 7.

[72] As shown in FIGS. 6 and 7, a refrigerator with a dispenser according to the present invention may include a refrigerator main body 110 having a cooling chamber therein, a door 125 for opening/closing the cooling chamber, and a dispenser 150 disposed at the door 125.

[73] The dispenser 150 may include a dispenser housing 151 having an accommodating space 152 therein, and a water supply unit 220 disposed inside the accommodating space 152 and implemented to adjust one of its height and direction.

[74] The water supply unit 220 may include a water supply tube 181 through which water is supplied, a flexible tube 221 having one end connected to the water supply tube 181, and a nozzle 191 connected to another end of the flexible tube 221.

[75] A manipulation lever 161 operated for allowing water to be dispensed is disposed inside the dispenser housing 151. The nozzle 191 is coupled to a ceiling of the accommodating space 152 of the dispenser housing 151, and a flexible tube receiving portion 171 for receiving the flexible tube 185 therein is formed at an upper area of the dispenser housing 151.

[76] A water supply tube 181 for supplying water is disposed in the flexible tube receiving portion 171. One end of the flexible tube 221 is connected to the water supply tube 181, and the nozzle 191 is disposed at the other end of the flexible tube 221. Here, the flexible tube 221 can be transformed, and preferably, after being transformed, such transformed shape is maintained, which allows an adjustment a water outlet direction via the nozzle 191.

[77] The nozzle 191 is disposed to be exposed at a ceiling of the accommodating space

152 of the dispenser housing 151. An insertion hole in which the flexible tube 221 is inserted is formed through the ceiling of the dispenser housing 151.

[78] With such configuration, when desiring to receive water in a relatively small container Cl, such as a cup, the container Cl is put in the accommodating space 152 of the dispenser housing 151, and the manipulation lever 161 is then manipulated, so as to receive water in the container Cl. On the other hand, desiring to receive water in a container C2 greater than the accommodating space 152, the nozzle 191 is rotated with respect to the dispensing housing 151 such that a water outlet direction of the nozzle 191 faces the container C2. Here, the nozzle 191 is continuously located at a position rotated due to the transformation of the flexible tube 221, thereby facilitating the water reception. Afterwards, upon manipulating the manipulation lever 161 or the input unit 155, water is dispensed via the nozzle 191.

[79] The aforementioned embodiments have illustrated a refrigerator with a dispenser, however, the dispenser can be configured to be disposed at a water purifier.
