[0131] FIG. 11 is a perspective view of a cover according to a first embodiment of the present invention viewed from the top, FIG. 12 is a perspective view of a cover according to a first embodiment of the present invention viewed from the bottom, and FIG. 13 is a cross-sectional view taken along 13-13 of FIG. 8.

[0132] Referring to FIGS. 8 to 13, a container (200) according to a first embodiment of the present invention may include a container body (210) and a cover (250) that covers the container body (210).

[0133] The above container (200) may further include a handle (230). The handle (230) may be formed integrally with the container body (210) or coupled with the container body (210).

[0134] Water and / or ice may be stored in the container body (210). The container body (210) includes an upper opening, and the cover (250) may cover the upper opening of the container body (210).

[0135] The above container body (210) may include a water outlet (214) for discharging water. The water outlet (214) may be formed by one side of the container body (210) being recessed outward.

[0136] The horizontal cross-sectional area of ​​the container body (210) may vary depending on the height. For example, the container body (210) may include a first body (211), a second body (212) extending upward from the first body (211), and a third body (213) extending upward from the second body (212). The horizontal cross-sectional area of ​​the second body (212) may be smaller than the horizontal cross-sectional area of ​​the first body (211). The horizontal cross-sectional area of ​​the third body (213) may be larger than the horizontal cross-sectional area of ​​the second body (212). However, it should be noted that in this embodiment, the shape of the container body (210) is not limited thereto and can be formed in various shapes.

[0137] The above cover (250) may include a cover body (251) having an opening (252) formed therein.

[0138] The opening (252) can provide a passage for water and ice. That is, when the second door (170) on which the container (200) is installed is closed, water or ice discharged from the dispenser (110) can be supplied into the container (200) through the opening (252).

[0139] The diameter of the opening (252) may be larger than the diameter of the ice.

[0140] The above cover (250) may further include an extension (253). The extension (253) may extend downward from the lower surface of the cover body (251). The extension (253) may change the direction of movement of the supplied water or ice.

[0141] The extension part (253) can prevent water from splashing out of the container (200) when water is supplied to the container (200) or when ice is supplied to the container (200) containing water. Therefore, the extension part (253) can also be called a water splash prevention part.

[0142] The extension part (253) can reduce the phenomenon of water overflowing from the container (200) when the first door (100) or the second door (170) is opened or closed while water or ice water is stored in the container (200). Therefore, the extension part (253) can also be called a water overflow prevention part.

[0143] The above extension (253) can reduce the phenomenon of water inside the container (200) overflowing to the outside of the container (200) during the process of moving the container (200) itself.

[0144] The extension portion (253) may include a first extension portion (254) extending downward from the periphery of the opening (252) and a second extension portion (255) extending from the first extension portion (254).

[0145] The second extension (255) may be bent from the first extension (254). The second extension (255) may include an inclined surface. The inclined surface may include a flat or rounded surface.

[0146] A portion of the opening (252) may overlap with the second extension (255) in the vertical direction. Another portion of the opening (252) may not overlap with the second extension (255) in the vertical direction.

[0147] Meanwhile, referring to FIG. 3, when the container (200) is mounted on the container mounting part (180), the handle (230) may be positioned to face the rear of the second door (170) or to face the first door (100). Thus, when the second door (170) is open, the user can easily grasp the handle (230).

[0148] Figure 14 is a schematic drawing showing a cross-section cut along 14-14 of Figure 3.

[0149] Referring to FIG. 14, the first door (100) may further include a passage for guiding ice discharged from the ice bin (134).

[0150] The above passage may include a first ice duct (115) located below the ice bin (134) and a second ice duct (116) that guides the ice passing through the first ice duct (115) to the discharge section (114). By operating the ice discharge section (135), the ice of the ice bin (134) can be discharged to the first ice duct (115).

[0151] The first door (100) may further include a cap duct (117) for opening and closing the first ice duct (115).

[0152] The above discharge section (114) may include an ice discharge port (118) through which ice is discharged and a water discharge port (119) through which water is discharged.

[0153] When the second door (170) equipped with the container (200) is closed, the ice discharge port (118) and the water discharge port (119) can be aligned with the opening (252) of the container (200). Thus, ice discharged from the ice discharge port (118) (see solid line) and / or water discharged from the water discharge port (119) (see dotted line) can be supplied into the container (200) through the opening (252).

[0154] As another example, the opening (252) may include an ice opening for ice to pass through and a water opening for water to pass through.

[0155] The above water level sensor (410) can come into contact with the container (200) at least when the second door (170) on which the container (200) is mounted is closed.

[0156] For example, the water level detection sensor (410) may be a contact type sensor. For example, the water level detection sensor (410) may be a contact type capacitive sensor.

[0157] The above water level detection sensor (410) may come into contact with a point of the container body (210). The point of the container body (210) may be the water level detection height of the container body (210).

[0158] Water (ice or ice water) or air may be positioned at the same height as the aforementioned point within the container body (210). Since air and water have different dielectric constants, the water level can be distinguished by the difference in dielectric constants between air and water. That is, if it is detected that water is supplied at the same height as the aforementioned point within the container body (210), it can be recognized that a reference water level has been detected. At this time, in order to prevent water from overflowing outside the container (200), the aforementioned point may be a point lower than the bottom of the extension part (253).

[0159] In this embodiment, since the water level detection sensor (410) is a contact type sensor, it may be important that the water level detection sensor (410) comes into contact with the container (200).

[0160] FIG. 15 is a diagram schematically illustrating various structures for a water level detection sensor to come into contact with a container.

[0161] Referring to FIG. 15 (a), the container (200) is mounted on the second door (170), and the water level sensor (410) may be provided on the second door (170).

[0162] The water level sensor (410) may be movably positioned on the second door (170) or the container mounting part (180). The water level sensor (410) may receive elastic force from an elastic member (430).

[0163] The above water level detection sensor (410) may protrude from the second door (170) or from the container mounting part (180), and when the container (200) is mounted on the container mounting part (180), the container (200) may come into contact with the water level detection sensor (410) while pressing the water level detection sensor (410).

[0164] Alternatively, if the water level detection sensor (410) does not protrude from the second door (170) or the container mounting part (180), the container (200) may include a contact projection. When the container (200) is mounted on the container mounting part (180), the contact projection may come into contact with the water level detection sensor (410). In this case, the contact projection may be formed at a height corresponding to a point for water level detection on the container (200).

[0165] As another example, referring to FIG. 15(b), the container (200) may be mounted on the second door (170), and the water level sensor (410) may be provided on the second door (170).

[0166] The above water level sensor (410) can be fixed in position at the second door (170) or the container mounting part (180).

[0167] The container mounting portion (180) may be provided with a pressurizing portion (190) for pressurizing the container (200). The pressurizing portion (190) may be movably positioned in the container mounting portion (180).

[0168] The above-mentioned pressurizing unit (190) can receive elastic force from an elastic member (431). When the container (200) is mounted on the container mounting unit (180), the pressurizing unit (190) pressurizes the container (200) toward the water level detection sensor (410), so that the container (200) can come into contact with the water level detection sensor (410).

[0169] As another example, referring to FIG. 15 (c), the container (200) may be mounted on the second door (170), and the water level sensor (410) may be provided on the first door (100).

[0170] The water level detection sensor (410) may be movably positioned on the first door (100). The water level detection sensor (410) may receive elastic force from an elastic member (432).

[0171] The above water level sensor (410) may protrude into the space (113) of the dispenser housing (112). When the second door (170) on which the container (200) is mounted is closed, the container (200) may come into contact with the water level sensor (410) while pressing against the water level sensor (410).

[0172] Alternatively, if the water level sensor (410) does not protrude into the space (113) of the dispenser housing (112), the container (200) may include a contact projection. When the second door (170) on which the container (200) is mounted is closed, it is also possible for the contact projection of the container (200) to come into contact with the water level sensor (410).

[0173] As another example, referring to (d) of FIG. 15, the container (200) may be mounted on the second door (170), and the water level sensor (410) may be provided on the first door (100).

[0174] The above water level detection sensor (410) can be fixed in position at the first door (100).

[0175] A pressurizing part (191) for pressurizing the container (200) may be provided in the container mounting part (180) or the second door (170). The pressurizing part (191) may be movably positioned in the container mounting part (180) or the second door (170).

[0176] The above-mentioned pressurizing unit (191) may receive elastic force from an elastic member (433). When the second door (170) on which the container (200) is mounted is closed, the pressurizing unit (190) pressurizes the container (200) toward the water level sensor (410) so that the container (200) can come into contact with the water level sensor (410). In order for the water level sensor (410) to easily come into contact with the container (200), the water level sensor (410) may protrude into the space (113) of the dispenser housing (112), or the container (200) may include a contact projection for contacting the water level sensor (410).

[0177] FIG. 16 is a diagram schematically showing various examples of mounting detection sensors for detecting the mounting of a container.

[0178] Referring to FIG. 16 (a), the container (200) includes a magnet (421), and the mounting detection sensor (420) may be a Hall sensor that detects the magnetism of the magnet (421).

[0179] The mounting detection sensor (420) may be placed, for example, in the second door (170) or in the container mounting section (180). However, if the mounting detection sensor (420) is placed in the container mounting section (180), the wire connected to the mounting detection sensor (420) may be guided to the second door (170).

[0180] Alternatively, a mounting detection sensor (420a), which is a Hall sensor, may be placed on the first door (100). In this case, when the second door (170) on which the container (200) is mounted is closed, the mounting detection sensor (420a) may detect the magnet (421) of the container (200). The mounting detection sensor (420a) may be installed, for example, on the dispenser housing (112).

[0181] As another example, referring to FIG. 16(b), the mounting detection sensor (422) may be an ultrasonic sensor. The mounting detection sensor (422) may be installed on the second door (170) or on the first door (100). If the ultrasonic sensor is installed on the first door (100), the mounting of the container (200) may be detected after the second door (170) is closed. If the ultrasonic sensor is installed on the second door (170), the mounting of the container (200) may be detected when the container (200) is mounted.

[0182] As another example, referring to (c) of FIG. 16, the mounted detection sensor (423) may be a light sensor. The light sensor may include a light-emitting part (423a) and a light-receiving part (423b).

[0183] The positions of the light-emitting part (423a) and the light-receiving part (423b) can be determined so that the container (200) is positioned between the light-emitting part (423a) and the light-receiving part (423b).

[0184] For example, the light-emitting part (423a) and the light-receiving part (423b) may be provided in the first door (100). In this case, the light-emitting part (423a) and the light-receiving part (423b) may be placed in the dispenser housing (112).

[0185] Alternatively, the light-emitting part (423a) and the light-receiving part (423b) may be provided in the second door (170) or the container mounting part (180).

[0186] Alternatively, either one of the light-emitting part (423a) and the light-receiving part (423b) may be placed in the first door (100), and the other may be placed in the second door (170).

[0187] As another example, referring to (d) of FIG. 16, the mounted detection sensor (424) may be a micro switch that is turned on or off by being pressurized by the container.

[0188] The micro switch may be placed in the container mounting portion (180) or the second door (170). Alternatively, the micro switch may be placed in the first door (100), and when the second door (170) on which the container (200) is mounted is closed, the container (200) may press the micro switch.

[0189] Below, the process of supplying water and / or ice to the above container (200) will be described.

[0190] After the second door (170) equipped with the container (200) is closed, water and / or ice can be supplied to the container (200) manually or automatically.

[0191] For example, when manual mode is selected, if the user inputs a water discharge command, an ice discharge command, or an ice water discharge command through the input unit (310), water, ice, or ice water can be discharged through the discharge unit (114) and supplied to the container (200) up to a reference water level.

[0192] When an ice water discharge command is entered, water may be supplied to the container (200) first, and then ice may be supplied to the container (200), or ice may be supplied to the container (200) first, and then water may be supplied to the container (200).

[0193] At this time, if the container is not detected by the mounting detection sensor (420), water and / or ice is not discharged, and information regarding the non-mounting of the container may be output through an output unit (speaker or display) not shown.

[0194] Alternatively, if automatic mode is selected, when the second door (170) is closed, water and / or ice can be automatically discharged through the discharge unit (114) and supplied to the container (200). At this time, the target (water and / or ice) to be discharged in automatic mode can be selected through the input unit (310).

[0195] Alternatively, after placing the container (200) on the bottom of the dispenser housing (112), a water discharge command, an ice discharge command, or an ice water discharge command can be input through the input unit (310). However, in this case, the water discharge command, an ice discharge command, or an ice water discharge command can be performed when the water discharge command, an ice discharge command, or an ice water discharge command is input through the input unit provided in the first door (100). That is, when the second door (170) is open, if a water discharge command, an ice discharge command, or an ice water discharge command is input through the input unit provided in the first door (100), water and / or ice can be discharged from the discharge unit (114) regardless of whether the container (200) is mounted. Of course, if a mounting detection sensor (420) is provided on the first door (100), when the second door (170) is open, if the container (200) (or various types of cups other than the container described above) is detected by the mounting detection sensor (420), it can be discharged from the discharge section (114).

[0196] FIG. 17 is a schematic drawing showing a container according to a second embodiment, and FIG. 18 is a drawing showing the opening of the container with the opening of the container open according to the second embodiment. FIG. 19 is a drawing showing the size of the opening of the container, the ice discharge port, and the water discharge port according to the second embodiment.

[0197] This embodiment is identical to the first embodiment in other respects, except that the container further includes an opening / closing unit for opening and closing the opening. Therefore, only the characteristic parts of this embodiment will be described below.

[0198] Referring to FIGS. 17 to 19, a container (200) according to a second embodiment of the present invention may include an opening / closing unit (520) for opening / closing an opening (252) of the cover (250).

[0199] The above opening / closing unit (520) can be installed on the cover (250).

[0200] The above opening / closing unit (510) may include a frame (510) coupled to the cover (250) and an opening / closing part (520) movably coupled to the frame (510).

[0201] The opening (252) can be opened or closed by moving the opening / closing part (520).

[0202] The above opening / closing unit (510) may further include an elastic member (530). The elastic member (530) may provide elastic force to the opening / closing part (520). The opening / closing part (520) may be slidably coupled to the frame (510). For example, the opening / closing part (520) may move in a straight line.

[0203] The elastic member (530) can, for example, elastically support the opening / closing part (520) within the space formed by the frame (510). The elastic member (530) may, for example, be a coil spring, a leaf spring, or a torsion spring.

[0204] The above opening / closing part (520) can move between an open position and a closed position. The position of the opening / closing part (520) in FIG. 17 may be a closed position, and the position of the opening / closing part (520) in FIG. 18 may be an open position.

[0205] The above opening / closing part (520) may include a hole (522) that is aligned with the opening (252) of the container (200) in the open position. Of course, the hole (522) may be omitted by changing the shape of the above opening / closing part (520).

[0206] Unless an external force is applied to the opening / closing part (520), the opening / closing part (520) can be maintained in a closed position by the elastic force of the elastic member (530).

[0207] During the process of closing the second door (170) equipped with the container (200), the opening / closing part (520) can move from the closed position to the open position.

[0208] The opening / closing part (520) can be moved to the open position by being pressed by a part of the dispenser (110) during the process of closing the second door (170). The part of the dispenser (110) may be, for example, the discharge part (114). That is, during the process of closing the second door (170), the opening / closing part (520) can be moved from the closed position to the open position by the discharge part (114).

[0209] When the opening / closing part (520) is moved to the open position, the hole (522) can be aligned with the opening (252). Additionally, when the second door (200) is closed, the opening (252) can be aligned with the ice discharge port (118) and the water discharge port (119).

[0210] In order for the ice discharged from the ice discharge port (118) to pass through the opening (252), the diameter (D2) of the opening (252) may be larger than the diameter (D1) of the ice discharge port (118).

[0211] The diameter (D2) of the opening (252) may be larger than the diameter of the water discharge port (119). The diameter (D2) of the opening (252) may be larger than the sum of the diameter (D1) of the ice discharge port (118) and the diameter of the water discharge port (119).

[0212] In order for water and ice to pass through the hole (522) of the opening / closing part (520), the diameter (D3) of the hole (522) may be the same as or larger than the diameter (D2) of the opening (252).

[0213] When the second door (170) is opened, the external force pressing the opening / closing part (520) is removed, so the opening / closing part (520) can move to the closed position by the elastic force of the elastic member (530).

[0214] According to the present embodiment, since the opening / closing part (520) can cover the opening (252) during the process of opening or closing the second door (170), the phenomenon of water overflowing outside the container (200) can be prevented.

[0215] In addition, even when the container (200) itself is moved, the opening / closing part (520) can cover the opening (252), so that water can be prevented from overflowing outside the container (200). In addition, foreign substances can be prevented from entering the container (200).

[0216] Meanwhile, the frame (510) may include a first extension part (512), and the opening / closing part (520) may include a first protrusion (524) that acts with the first extension part (512). The first protrusion (524) may, for example, be formed on the upper surface of the opening / closing part (520).

[0217] The above frame (510) may include a second extension part (513), and the opening / closing part (520) may include a second protrusion that acts with the second extension part (513). The second protrusion may be formed on the side of the opening / closing part (520).

[0218] It should be noted that in this embodiment, the structure for guiding the movement of the opening / closing part (520) is exemplary and various types of extension parts may be applied.

[0219] If a structure for guiding the movement of the opening / closing part (520) is formed in the cover body (251), the frame (510) may be omitted. In this case, the guide not only guides the movement of the opening / closing part (520) but also limits the separation of the opening / closing part (520).

[0220] Meanwhile, although the above embodiment describes the opening / closing part (520) moving in a straight line, it is also possible for the opening / closing part (520) to pivot or rotate relative to the shaft.

[0221] That is, when the second door (170) is closed while the opening / closing part (520) is in the closed position, the opening / closing part (520) can pivot or rotate and move to the open position by a part of the dispenser (110). Of course, when the external force applied to the opening / closing part (520) is removed, the opening / closing part can return to the closed position by means of elastic force. In this case, the frame (110) can be omitted.

[0222] In the case of this embodiment as well, the cover (250) may include the extension part (253) described in the first embodiment. Alternatively, the extension part (253) may be omitted from the cover (250).

[0223] FIG. 20 is a diagram showing the arrangement relationship between a water level sensing sensor and a container according to a third embodiment of the present invention.

[0224] This embodiment is identical to the previous embodiment in other respects, except for the difference in the type and arrangement of the water level sensor. Therefore, only the characteristic parts of this embodiment will be described below.

[0225] Referring to FIG. 20, the water level detection sensor (412) of the present embodiment may be, for example, an ultrasonic sensor.

[0226] The ultrasonic sensor may be located on the upper side of the container (200). For example, the ultrasonic sensor may be located on the second door (170) or on the first door (100).

[0227] In any case, the ultrasonic sensor can be aligned with the opening (252) of the container (200). When the ultrasonic sensor is located in the first door (100), the ultrasonic sensor can be aligned with the opening (252) of the container (200) when the second door (170) on which the container (200) is mounted is closed.

[0228] On the other hand, when the ultrasonic sensor is located in the second door (170), the container (200) is mounted in the container mounting part (180), so that the ultrasonic sensor can be aligned with the opening (252) of the container (200). In order to prevent the ultrasonic waves from interfering with the extension part (253), the ultrasonic sensor can be non-overlapping with the extension part (253) in the cover (250).

[0229] By using the above-described ultrasonic sensor, the water level can be detected by measuring the distance from the ultrasonic sensor to the water surface. In particular, by using the above-described ultrasonic sensor, not only can a specific water level be detected, but changes in the water level can also be detected.

[0230] As another example, a detection hole may be separately formed in the cover (250) so that the ultrasonic sensor is aligned with the detection hole of the container (200). In this case, the detection hole may be spaced apart from the opening and may be formed smaller than the diameter of the opening (252). Thus, water level detection is possible through the detection hole, while preventing water from overflowing outside the container through the detection hole.

[0231] FIG. 21 is a drawing showing the state in which the second door is opened in the refrigerator door according to the fourth embodiment of the present invention.

[0232] This embodiment is identical to previous embodiments in other respects, except that the basket is omitted in the second door. Therefore, the characteristic parts of this embodiment will be described below.

[0233] Referring to FIG. 21, in the case of the present embodiment, a basket may not be installed on the second door (170). In this case, the storage space (120) formed in the first door (100) may be omitted or the depth of the storage space (120) may be reduced. Thus, there is an advantage in that the overall thickness of the door (20) can be reduced.

[0234] FIG. 22 is a drawing showing a refrigerator door according to the fifth embodiment of the present invention.

[0235] This embodiment is identical to previous embodiments in other respects, except that the second door includes a panel assembly capable of transmitting light. Accordingly, the characteristic parts of this embodiment will be described below.

[0236] Referring to FIG. 22, in the case of the present embodiment, the second door (170) may include a panel assembly (600). Additionally, the first door (100), the second door (170), or the cabinet (10) may be equipped with a lighting unit (not shown).

[0237] The panel assembly (600) may include one or more panels capable of transmitting light. The panels may be formed of glass material or plastic material.

[0238] From an insulation perspective, the panel assembly (600) may include a first panel, a second panel spaced apart from the first panel, and a spacer disposed between the first panel and the second panel. In this case, an insulating space may be formed between the first panel and the second panel.

[0239] Although not shown, the lighting unit may be turned on when it is detected that an operation command for the lighting unit has been input from the sensor. The sensor may be a sensor of various types, such as a sensor for detecting knocks or a sensor for detecting touches.

[0240] When the above lighting unit is turned on, the container (200) can be checked from the outside of the refrigerator (1) through the panel assembly (600) while the second door (170) is closed. Thus, the amount of water (or ice or ice water) stored in the container (200) can be checked.

[0241] FIG. 23 is a drawing showing the state in which the second door is opened in the refrigerator door according to the 6th embodiment of the present invention.

[0242] This embodiment is identical to previous embodiments in other respects, except that the dispenser housing includes a rear opening. Therefore, the characteristic parts of this embodiment will be described below.

[0243] Referring to FIG. 23, the dispenser housing (112) may include a rear opening (113a). Thus, the space (113) formed by the dispenser housing (112) may be in communication with the refrigerator room (11).

[0244] Then, when the refrigerator door (21) is closed, the water or ice inside the container (200) can be maintained at a low temperature by the cold air of the refrigerator (11).

[0245] FIG. 24 is a drawing showing the state in which the second door is opened in the refrigerator door according to the 7th embodiment of the present invention.

[0246] This embodiment is identical to previous embodiments in other respects, except for the position of the handle on the container. Therefore, the characteristic parts of this embodiment will be described below.

[0247] Referring to FIG. 24, in the present embodiment, the container (200A) can be mounted on the container mounting part (180A) with the handle (230A) of the container (200A) positioned to face one side. The one side may be a direction facing the door adjacent to the door (20) when the door (20) is closed.

[0248] In this case as well, when the second door (170) is opened, the user can easily grab the handle (230A).

[0249] In addition to the above embodiments, the present specification may further include the following embodiments.

[0250] As another embodiment, in addition to the ice bin where ice produced from an ice maker is stored, the container may also serve as an ice bin. For example, the ice bin located in the ice-making room may be the main ice bin (or first ice bin), and the container may be the sub ice bin (or second ice bin).

[0251] With the second door (170) closed, the ice stored in the main ice bin can be discharged from the main ice bin and supplied to the sub ice bin by the operation of the ice discharge unit (135). Thus, ice can be stored in the sub ice bin. In this state, water can be supplied to the sub ice bin by the user's choice. The amount of ice stored in the sub ice bin can be determined based on the level detected by the water level sensor (410) or by the operating time of the ice discharge unit (135).

[0252] The ice stored in the main ice bin can be supplied to the sub ice bin automatically or manually.

[0253] For example, if fullness is detected in the main ice bin, the ice stored in the main ice bin can be supplied to the sub ice bin.

[0254] Alternatively, if the non-operation time of the ice discharge unit (135) in the main ice bin exceeds a reference time, the ice stored in the main ice bin may be supplied to the sub ice bin.

[0255] Alternatively, ice stored in the main ice bin may be supplied to the sub ice bin based on a pattern of ice discharge from the main ice bin, for example, a user's ice usage pattern. The user's ice usage pattern may be stored in a memory not illustrated. For example, ice stored in the main ice bin may be supplied to the sub ice bin at a specific time, on a specific date, or on a specific day of the week. Alternatively, ice stored in the main ice bin may be supplied to the sub ice bin at a time, date, or day of the week specified by the user.

[0256] Alternatively, if the user selects a sub ice bean mode through the input unit, the ice stored in the main ice bean can be supplied to the sub ice bean.

[0257] As another embodiment, the container may also function as an ice bin independently of the ice bin where ice produced in the ice maker is stored. For example, the ice bin located in the ice-making room may be the first ice bin, and the container may be the second ice bin.

[0258] At this time, although not shown, an independent passage may be provided in the first door to directly transfer ice generated from the ice maker to the second ice bin.

[0259] Accordingly, the ice generated in the ice maker may be stored in the first ice bin or stored in the second ice bin through a separate passage. The ice stored in the first ice bin may be guided to the ice discharge port through the first passage. The second passage may guide the ice generated in the ice maker to the ice discharge port.

[0260] Alternatively, when ice is produced in the ice maker, some of the ice produced in the ice maker may be stored in the first ice bin, and other parts may be stored in a separate second passage for the second ice bin. When the second passage is opened, ice may be supplied to the second ice bin.

[0261] Alternatively, the ice maker may include a first ice maker for the first ice bean and a second ice maker for the second ice bean.

[0262] Alternatively, the ice bin provided in the ice-making chamber may be omitted. In this case, the ice generated by the ice maker may be stored in the ice passage, and when the ice passage is opened, the ice may be supplied to the container.
