BACKGROUND

A refrigerator is an apparatus for storing food for by keeping a refrigeration compartment and a freezing compartment at a low temperature using a heat exchange process involving a refrigerant, where a freezing cycle consisting of compression, condensation, expansion and evaporation is used to generate cold air.
In general, a refrigerator includes a refrigerator main body with a freezing compartment and a refrigeration compartment for storing food at a low temperature, and refrigerator doors mounted to a front surface of the refrigerator main body to selectively open and close the freezing compartment and the refrigeration compartment.
Top-mount refrigerators with a freezing compartment disposed above a refrigeration compartment are a common type of refrigerator. In recent years, bottom-freeze refrigerators with a freezing compartment positioned at a lower end of the refrigerator have become popular due to enhanced user convenience. However, for bottom-freeze refrigerators, the freezing compartment is positioned lower which may be inconvenient when a user wants to retrieve ice from the freezer.
In order to solve this problem, bottom-freeze refrigerator may include a dispenser disposed on a refrigeration compartment door for dispensing ice. The dispenser is installed in the refrigeration compartment door, and a user may dispense ice by placing a container on the dispenser and pressing a push member or a button, for example.
However, the ice may be scattered around in the course of dispensing the ice through the dispenser and may become lodged in other parts of the refrigerator. This may lead to sanitary problems when ice and/or water sits in areas of the refrigerator that are intended to be kept dry. Accordingly, a demand exists for a dispenser that enables ice pieces to be discharged only through a specified route without being scattered around the refrigerator.

FIG. 1 is a schematic perspective view illustrating an exemplary refrigerator 1 according to one embodiment of the present disclosure. FIG. 2 is an enlarged view of a region designated A in FIG. 1.
Referring to FIGS. 1 and 2, an exemplary refrigerator according to one embodiment of the present disclosure includes a refrigerator main body 11 configured to define an outer shell, refrigerator doors 12 (12 a and 12 b) coupled to the refrigerator main body 11 to selectively open and close the refrigerator main body 11, a dispenser module 100 installed in one of the refrigerator doors 12, and an ice maker 14 provided inside the refrigerator main body 11 and configured to supply ice to the dispenser module 100.
The bottom-freeze refrigerator 1 includes a freezing compartment at a lower side thereof. However, the present disclosure is not limited thereto. The present disclosure may be applicable to different types of refrigerators such as a top-mount refrigerator and other types which are widely used in the related art.
The refrigerator main body 11 may include an internal space which may be selectively opened and closed by the refrigerator doors 12. For example, the interior of the refrigerator main body 11 may be divided into a refrigeration compartment R and a freezing compartment F, which may be selectively opened and closed by a refrigeration compartment door 12 a and a freezing compartment door 12 b, respectively.
The dispenser module 100 may be disposed on one of the refrigerator doors 12. For example, the dispenser module 100 may be disposed on an outer surface of the refrigeration compartment door 12 a. An opening 11 a may be provided in the refrigeration compartment door 12 a. A push lever 140 of the dispenser module 100 may be accessible through the opening 11 a to enable a user to use the dispenser module 100 without having to open the refrigeration compartment door 12 a.
The ice maker 14 is configured to receive water from an external water source and to produce ice, and may be provided inside the refrigeration compartment R. The ice maker 14 and the dispenser module 100 may be connected to each other by a separate connection pipe 13 (see FIG. 6). The ice produced in the ice maker 14 may be discharged through the dispenser module 100. For example, the ice maker 14 may supply the ice to the dispenser module 100 in response to a signal transmitted from a switch 150.
FIG. 3A is a schematic perspective view of an exemplary dispenser module 100 according to one embodiment of the present disclosure, and FIG. 3B is a schematic perspective view of the dispenser module 100 illustrated in FIG. 3A, viewed from a second angle. FIG. 4A is a schematic perspective view of the dispenser module 100 with an ice cap thereof removed, and FIG. 4B is a schematic perspective view of the dispenser module 100 illustrated in FIG. 4A viewed from a second angle. FIG. 5 is a schematic side view of the dispenser module 100 according to one embodiment of the present disclosure. FIG. 6 is a schematic sectional view illustrating an exemplary process for discharging ice from the dispenser module 100 according to one embodiment of the present disclosure.
Referring to FIGS. 3A to 6, the dispenser module 100, according to one embodiment of the present disclosure, may be provided in the refrigerator 1 to dispense ice. For example, the dispenser module 100 may be provided on a surface of the refrigeration compartment door 12 a in order to enable a user to easily obtain ice from the refrigerator 1.
The dispenser module 100 may include a dispenser body 110, a guide wall 120, an ice cap 130, a push lever 140 and a switch 150.
The dispenser body 110 may be coupled to one of the refrigerator doors 12, and may use a shoot or pathway for discharging ice, such as discharge port 110 a.
The guide wall 120 may protrude from an edge of the dispenser body 110. When the ice is discharged through the dispenser module 100, the guide wall 120 prevents the ice from being scattered outward. With regard to FIG. 6, when the ice I is supplied to the dispenser module 100, some of the ice I may not enter the discharge port 110 a and may move to the outside of the discharge port 110 a after colliding with the dispenser body 110. In this case, the guide wall 120 prevents the ice from being scattered outward and guides the ice toward the discharge port 110 a.
For example, the guide wall 120 may surround at least a portion of the discharge port 110 a. The ice cap 130 may be disposed on a portion of the discharge port 110 a not covered by the guide wall 120.
The guide wall 120 may be provided along at least a portion of the edge of the dispenser body 110 and extend upward. The upper end of the guide wall 120 may be disposed above the ice cap 130.
For example, the guide wall 120 may include sidewalls 121 disposed at the opposite sides of the ice cap 130 and a rear wall portion 122 configured to interconnect the sidewalls 121 and face the ice cap 130.
In this regard, the upper ends of the sidewalls 121 and the rear wall portion 122 may be disposed on the same plane. In other words, the sidewalls 121 and the rear wall portion 122 may be provided along at least a portion of an edge of the discharge port 110 a and protrude upward to guide the ice discharged from the ice maker 14 toward the discharge port 110 a.
The guide wall 120 and the dispenser body 110 may be combined as a single object or provided as separate components. For example, the guide wall 120 may be manufactured using injection-molding, where the guide wall 120 and the dispenser body 110 are formed into a single component. Alternatively, the guide wall 120 may be independently manufactured and fixed to the dispenser body 110 by bonding, screw-fixing or other methods.
The ice cap 130 may be mounted to the guide wall 120 in a rotatable or hinged manner. In one example, the ice cap 130 may be mounted to the sidewalls 121 of the guide wall 120 using a hinge. The ice cap 130 may be connected to a separate drive unit 160 and may be rotated by the drive unit 160. In this regard, the drive unit 160 may rotate the ice cap 130 in response to a signal applied from the switch 150.
The ice cap 130 may include a shaft 131 mounted to the sidewalls 121 using a hinge, and a stopper 132 connected to the shaft 131 and configured to open and/or close a route through which ice is moved toward the discharge port 110 a.
The sidewalls 121 may include a first insertion hole 121 a and a second insertion hole 121 b into which the shaft 131 is rotatably inserted. In this regard, one side of the first insertion hole 121 a may include a slit or narrow opening. When the shaft 131 of the ice cap 130 is combined with the sidewalls 121, an end portion of the shaft 131 may be inserted into the second insertion hole 121 b, and another end portion of the shaft 131 may be pressed into to the first insertion hole 121 a.
An elastic member 133 configured to apply a restoration force to the ice cap 130 may be disposed on one end portion of the shaft 131. The elastic member 133 may be, for example, a coil spring or a torsion spring. When the ice cap 130 is rotated in one direction by the drive unit 160, the elastic member 133 may provide a rotational force for returning the ice cap 130 to an original position. When the ice cap 130 is rotated by the drive unit 160, the end portion of the ice cap 130 may make contact with the inner surface of the rear wall portion 122.
The operation of the drive unit 160 may be controlled by the switch 150 provided at one side of the dispenser body 110. The switch 150 may sense the rotation of the push lever 140 and may transmit a start signal or a stop signal to the drive unit 160.
The push lever 140 may make contact with the switch 150. When the push lever 140 is brought into contact with the switch 150, the switch 150 may transmit a signal to the drive unit 160 and the ice maker 14. Upon receiving the signal from the switch 150, the drive unit 160 rotates the ice cap 130 and opens the discharge port 110 a. In this way, the ice maker 14 can supply ice to the dispenser module 100. Because the discharge port 110 a is opened by a rotation of the ice cap 130, the ice supplied from the ice maker 14 can be discharged through the discharge port 110 a. When discharging ice, some ice may collide with the pipe 13, which interconnects the ice maker 14 and the dispenser module 100, or the dispenser body 110. However, the guide wall 120 prevents the ice from being scattered or discharged through a route other than the route provided by the discharge port 110 a.
The push lever 140 may be mounted to the dispenser body 110 in a hinged manner. For example, one end portion of the push lever 140 may be rotatably mounted to the dispenser body 110 and the other end portion of the push lever 140 may extend away from the guide wall 120. In this way, at least a portion of the push lever 140 may be exposed through the opening 11 a of the refrigeration compartment door 12 a. Accordingly, a user may push the push lever 140 using a cup, container (e.g., container B) or the like without having to open the refrigerator door 12.
If a user pushes the push lever 140, a switch contact projection 141 disposed at one side of the push lever 140 may be rotated to press the switch 150. As the switch contact projection 141 presses the switch 150, the ice discharge process is performed as described above.
The method of operating the switch 150 may be changed to many different methods widely used in the related art. For example, a separate photo sensor may be installed so that a switch is operated when a container is detected by the photo sensor. Alternatively, a pressure sensor may be installed on the surface on which a container is seated, so that a switch is operated when a container is detected by the pressure sensor.
The dispenser module 100 according to one embodiment of the present disclosure includes the guide wall 120 which surrounds at least a portion of an edge of the discharge port 110 a for preventing ice from being scattered in the refrigerator or moved away from the intended route. In addition, the guide wall 120 is an integral part of the dispenser module 100. Therefore, there is no need to install a separate guide member in the dispenser body 110 to prevent ice from moving away from the specified movement route.
From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. The exemplary embodiments disclosed in the specification of the present disclosure do not limit the present disclosure. The scope of the present disclosure will be interpreted by the claims below, and it will be construed that all techniques within the scope equivalent thereto belong to the scope of the present disclosure.
