[0131] 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.

[0132] 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).

[0133] 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.

[0134] 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.

[0135] Figure 7 is a schematic diagram showing a cross-section cut along 7-7 of Figure 2.

[0136] Referring to FIG. 7, the first door (100) may further include a passage for guiding ice discharged from the ice bin (134).

[0137] 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).

[0138] The first door (100) may further include a cap duct (117) for opening and closing the first ice duct (115).

[0139] 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.

[0140] 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). Accordingly, ice discharged from the ice discharge port (118) and water discharged from the water discharge port (119) can be supplied into the container (200) through the opening (252).

[0141] 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.

[0142] The above water level sensor (410) can come into contact with the container (200) when the second door (170) on which the container (200) is mounted is closed.

[0143] 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.

[0144] The above water level detection sensor (410) may include a first sensor (411). The first sensor (411) may come into contact with a first part of the container body (210). The first part of the container body (200) may be a part for detecting a first water level (first level or first height) (H1) of the container body (210).

[0145] The above water level detection sensor (410) may further include a second sensor (412). The first sensor (411) and the second sensor (412) may be placed at different heights.

[0146] The second sensor (412) may come into contact with a second part of the container body (210). The second part of the container body (200) may be a part for detecting a second water level (second level or second water level) (H2) of the container body (210). The second sensor (412) may be positioned higher than the first sensor (411).

[0147] Water (ice or ice water) or air may be positioned at the same height as the first part within the container body (200). 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 first part within the container body (200), it can be recognized that the first water level has been detected.

[0148] Water (ice or ice water) or air may be positioned at the same height as the second part within the container body (200). When water is detected being supplied at the same height as the first part within the container body (200), it may be recognized that the second water level has been detected.

[0149] At this time, the second water level can be set to a height lower than the bottom of the extension part (253) so as to prevent water from overflowing outside the container (200).

[0150] The above first water level may be a standard water level at which water can be primarily supplied when water is supplied.

[0151] The second water level may be a limiting water level to prevent water or ice from being supplied any further. That is, water, ice, or ice water may be supplied up to the second water level within the container. Although not limited, the second water level may be a water level lower than the bottom of the extension (253).

[0152] Figure 8 is a diagram schematically showing various examples of mounting detection sensors for detecting the mounting of a container.

[0153] Referring to FIG. 8(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).

[0154] 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).

[0155] 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).

[0156] As another example, referring to FIG. 8(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.

[0157] As another example, referring to FIG. 8(c), 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).

[0158] 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).

[0159] 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).

[0160] 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).

[0161] 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).

[0162] As another example, referring to Fig. 8 (d), the mounting detection sensor (424) may be a micro switch that is turned on or off by being pressurized by the container.

[0163] 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.

[0164] Below, the process of supplying water and / or ice to the above container (200) will be described.

[0165] FIG. 9 is a flowchart illustrating a first method of supplying ice water to a container of the present invention.

[0166] Referring to FIG. 9, the first method is a method in which ice water is supplied to a container by inputting an ice water discharge command by a user (manual mode).

[0167] The second door (170) can be opened to supply water and / or ice to the container (200) (S1).

[0168] With the second door (170) open, the container (200) can be mounted on the second door (170) (S2).

[0169] Next, the second door (170) can be closed (S3).

[0170] After the second door (170) equipped with the container (200) is closed, an ice water discharge command can be input through the first input unit (311) (S4).

[0171] When the above ice water discharge command is input, water can be supplied to the container (200) up to the first water level (S5). That is, the valve (302) is opened so that water is supplied to the container (200), and when the first water level is detected by the first sensor (411), the valve (302) can be closed.

[0172] After water is supplied up to the first water level, ice can be supplied to the container (200) up to the second water level (S6).

[0173] For example, the ice discharge unit (135) may be operated to discharge ice from the ice bin (134). The ice discharged from the ice bin (134) may pass through the ice duct (115, 116) and then be discharged from the ice discharge port (118). The ice discharged from the ice discharge port (118) may be supplied to the container (200) through the opening (252).

[0174] When ice is supplied to the container (200), the water level inside the container (200) increases, and when the second water level is detected by the second sensor (412), the operation of the ice discharge unit (135) can be stopped.

[0175] Accordingly, according to the present embodiment, the ice water can be supplied from the container (200) to the second water level.

[0176] According to the present embodiment, since ice and water can be supplied together to the container, the user has the advantage of being able to drink ice water.

[0177] Since the second water level is a lower water level than the extension (253), the extension (253) is not submerged in water, and the ice is prevented from interfering with the extension (253). Therefore, the water is prevented from overflowing outside the container (200).

[0178] FIG. 10 is a flowchart illustrating a second method of supplying ice water to a container of the present invention.

[0179] Referring to FIG. 10, the second method is a method in which ice water is supplied to a container by inputting an ice water discharge command by a user (manual mode).

[0180] The second door (170) can be opened to supply water and / or ice to the container (200) (S11).

[0181] With the second door (170) open, the container (200) can be mounted on the second door (170) (S12).

[0182] Next, an ice water discharge command can be input through the first input unit (311) or the second input unit (312) (S13). When the second door (170) is open, the user can easily access the second input unit (312) and input an ice water discharge command through the second input unit (312). It is also possible to input a command using the first input unit (311).

[0183] After the above ice water discharge command is entered, the second door (170) can be closed (S4).

[0184] When the second door (170) is closed, water can be supplied to the container (200) up to the first water level (S15). That is, when the valve (302) is opened and water is supplied to the container (200), and the first water level is detected by the first sensor (411), the valve (302) can be closed.

[0185] After water is supplied up to the first water level, ice can be supplied to the container (200) up to the second water level (S16).

[0186] As described above, the ice discharge unit (135) can be operated to discharge ice from the ice bin (134). The ice discharged from the ice bin (134) can be discharged from the ice discharge port (118) after passing through the ice duct (115, 116). The ice discharged from the ice discharge port (118) can be supplied to the container (200) through the opening (252).

[0187] When ice is supplied to the container (200), the water level inside the container (200) increases, and when the second water level is detected by the second sensor (412), the operation of the ice discharge unit (135) can be stopped.

[0188] FIG. 11 is a flowchart illustrating a variation of the first method of supplying ice water to a container of the present invention.

[0189] Referring to FIG. 11, the second door (170) can be opened to supply water and / or ice to the container (200) (S21).

[0190] With the second door (170) open, the container (200) can be mounted on the second door (170) (S22).

[0191] Next, the second door (170) can be closed (S23).

[0192] After the second door (170) equipped with the container (200) is closed, an ice water discharge command can be input through the first input unit (311) (S24).

[0193] When the above ice water discharge command is input, water can be supplied to the container (200) up to the first water level (S25). That is, the valve (302) is opened so that water is supplied to the container (200), and when the first water level is detected by the first sensor (411), the valve (302) can be closed.

[0194] After water is supplied up to the first water level, a set amount of ice can be supplied to the container (200) (S26).

[0195] For example, the ice discharge unit (135) may be operated to discharge ice from the ice bin (134). The ice discharged from the ice bin (134) may pass through the ice duct (115, 116) and then be discharged from the ice discharge port (118). The ice discharged from the ice discharge port (118) may be supplied to the container (200) through the opening (252). At this time, the operating time of the ice discharge unit (135) may be predetermined.

[0196] That is, when the ice discharge unit (135) operates for a predetermined operating time, a set amount of ice can be supplied to the container (200).

[0197] After ice is supplied to the container (200), it can be determined whether the water level inside the container (200) has reached a second water level (S27).

[0198] In step S27, if the second water level is detected by the second sensor (412) as a result of the judgment, the supply of ice water may be terminated.

[0199] On the other hand, if, as a result of the judgment in step S27, the second water level is not detected by the second sensor (412), water may be additionally supplied to the container (200) until the second water level is detected by the second sensor (412) (S28).

[0200] FIG. 12 is a flowchart illustrating a third method of supplying ice water to a container of the present invention.

[0201] Referring to FIG. 12, the third method may be a method in which ice water is automatically supplied to a container (automatic mode).

[0202] The second door (170) can be opened to supply water and / or ice to the container (200) (S31).

[0203] With the second door (170) open, the container (200) can be mounted on the second door (170) (S32).

[0204] Next, the second door (170) can be closed (S33).

[0205] When the second door (170) equipped with the container (200) is closed, water can be automatically supplied to the container (200) up to the first water level (S34). That is, water can be automatically supplied to the container (200) when the second door (170) is closed, without the user having to input a separate ice water discharge command.

[0206] When the valve (302) is opened and water is supplied to the container (200), and when the first water level is detected by the first sensor (411), the valve (302) can be closed.

[0207] After water is supplied up to the first level, ice can be supplied to the container (200) up to the second level (S34). For example, the ice discharge unit (135) can be operated to discharge ice from the ice bin (134). The ice discharged from the ice bin (134) can be discharged from the ice discharge port (118) after passing through the ice duct (115, 116). The ice discharged from the ice discharge port (118) can be supplied to the container (200) through the opening (252).

[0208] When ice is supplied to the container (200), the water level inside the container (200) increases, and when the second water level is detected by the second sensor (412), the operation of the ice discharge unit (135) can be stopped.

[0209] Accordingly, according to the present embodiment, there is an advantage that ice water can be supplied to the container (200) without user command input.

[0210] FIG. 13 is a flowchart illustrating a variation of the third method of supplying ice water to a container of the present invention.

[0211] Referring to FIG. 13, the second door (170) can be opened to supply water and / or ice to the container (200) (S41).

[0212] With the second door (170) open, the container (200) can be mounted on the second door (170) (S42).

[0213] Next, the second door (170) can be closed (S43).

[0214] When the second door (170) equipped with the container (200) is closed, ice can be automatically supplied to the container (200) to a first level (S44). Alternatively, a set amount of ice can be supplied to the container (200).

[0215] That is, ice can be automatically supplied to the container (200) when the second door (170) is closed, without the user entering a separate ice water discharge command.

[0216] After ice is supplied up to the first level, water can be supplied to the container (200) up to the second level (second water level) (S45).

[0217] When water is supplied to the container (200), the water level in the container (200) increases, and when the second level is detected by the second sensor (412), the operation of the valve (302) can be stopped.

[0218] FIG. 14 is a flowchart illustrating a fourth method of supplying water to a container of the present invention.

[0219] Referring to FIG. 14, the fourth method is a method for a user to supply additional water or ice after water has been automatically supplied to a first level.

[0220] The second door (170) can be opened to supply water and / or ice to the container (200) (S51).

[0221] With the second door (170) open, the container (200) can be mounted on the second door (170) (S52).

[0222] Next, the second door (170) can be closed (S53).

[0223] When the second door (170) equipped with the container (200) is closed, water can be automatically supplied to the container (200) up to the first water level (S54).

[0224] That is, water can be automatically supplied to the container (200) when the second door (170) is closed, without the user entering a separate water discharge command.

[0225] After the ice is supplied up to the first water level, it can be determined whether a water discharge command has been entered through the first input unit (311) (S55).

[0226] If, as a result of judgment in step S55, it is determined that the water discharge command has been entered, the water can be supplied to the container (200) up to the second water level (S56).

[0227] On the other hand, if it is determined at step S55 that the water discharge command was not entered, it can be determined whether the ice discharge command was entered (S57).

[0228] If, as a result of judgment in step S57, it is determined that the ice discharge command has been entered, ice can be supplied to the container (200) until the second water level is detected (S58).

[0229] In the case of this embodiment, when the second door (170) is closed, water can be automatically supplied to the container (200) up to the first water level, and thereafter, water or ice can be additionally supplied to the container (200) by the user's choice.

[0230] FIG. 15 is a flowchart illustrating a fifth method of supplying one or more of water and ice to a container of the present invention.

[0231] Referring to FIG. 15, the fifth method relates to a method of manually selecting any one of a water discharge command, an ice discharge command, and an ice water discharge command.

[0232] The second door (170) can be opened to supply water and / or ice to the container (200) (S61).

[0233] With the second door (170) open, the container (200) can be mounted on the second door (170) (S62).

[0234] Next, the second door (170) can be closed (S63).

[0235] When the second door (170) equipped with the container (200) is closed, it can be determined whether a water discharge command has been entered (S64).

[0236] If, as a result of the judgment in step S64, it is determined that a water discharge command has been entered, water can be supplied to the container (200) up to the reference water level (S65).

[0237] The above standard water level can be set to the first water level by user selection or automatically, and can be changed to the second water level.

[0238] If, as a result of the judgment in step S64, it is determined that the water discharge command has not been entered, it can be determined whether the ice discharge command has been entered (S66).

[0239] If, as a result of the judgment in step S66, it is determined that an ice discharge command has been entered, ice can be supplied to the container (200) up to a reference height (S67). Alternatively, if it is determined that an ice discharge command has been entered, a certain amount of ice can be supplied to the container (200). The reference height can be set to the first height by user selection or automatically, and can be changed to the second level.

[0240] If, as a result of the judgment in step S66, it is determined that the ice discharge command has not been entered, it can be determined whether the ice water discharge command has been entered (S68).

[0241] If, as a result of the judgment in step S68, it is determined that an ice water discharge command has been entered, water can be supplied to the container (200) up to a first water level (S69). Then, ice can be supplied to the container (200) until the second water level is detected (S70).

[0242] In this embodiment, the order of step S69 and step S70 may be reversed.

[0243] Meanwhile, with the second door (170) open, the user can place the container (200) or other types of cups, etc., in the space (113) of the dispenser housing (112), and then input any one of a water discharge command, an ice discharge command, or an ice water discharge command through the second input unit (312).

[0244] When a water discharge command is input through the second input unit (312), water can be supplied to the container (200) up to the reference water level, and the reference water level can be changed.

[0245] When an ice discharge command is input through the second input unit (312), ice can be supplied to the container (200) up to the reference height, and the reference height can be changed.

[0246] When an ice water discharge command is input through the third input unit (312), water is supplied to the container (200) to a first level, and then ice is supplied to the container (200) until a second level is detected. Of course, the order of supplying water and ice may be reversed.

[0247] Meanwhile, in the present embodiment, 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.

[0248] FIG. 16 is a diagram showing the arrangement relationship between a water level sensing sensor and a container according to a second embodiment of the present invention.

[0249] This embodiment is identical to the first embodiment in other respects, except that there is a difference in the type and arrangement of the water level sensor. Therefore, only the characteristic parts of this embodiment will be described below.

[0250] Referring to FIG. 16, the water level detection sensor (413) of the present embodiment may be, for example, an ultrasonic sensor.

[0251] 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).

[0252] 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.

[0253] 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 not overlapped with the extension part (253) in the cover (250).

[0254] 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.

[0255] That is, by using the above ultrasonic sensor, it is possible to detect the first water level (first level) and the second water level (second level).

[0256] 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.

[0257] Even when using the above-mentioned ultrasonic sensor, the first to third methods and variations for supplying ice water to the container described above can be applied as they are.

[0258] FIG. 17 is a flowchart illustrating a method for supplying ice water to a container according to a second embodiment of the present invention.

[0259] Referring to FIG. 17, the method of supplying ice water to a container in the present embodiment is a method in which ice water is supplied to the container by inputting an ice water discharge command by a user (manual mode).

[0260] Various containers may be mounted on the second door (170). Accordingly, the container (200) mentioned below may be a container with a cover removed, a container without a cover, or a container with a cover mounted.

[0261] The second door (170) can be opened to supply water and / or ice to the container (200) (S81).

[0262] With the second door (170) open, the container (200) can be mounted on the second door (170) (S82).

[0263] Then, the second door (170) can be closed (S83).

[0264] After the second door (170) equipped with the container (200) is closed, an ice water discharge command can be input through the first input unit (311) (S84).

[0265] Before or after the above ice water discharge command is input, the water level inside the container (200) can be detected by the ultrasonic sensor.

[0266] It can be determined whether the water level in the above container (200) is within the standard water level (S85).

[0267] The above reference water level may be a water level lower than the above first water level, and may include cases where the water level is 0.

[0268] The user may mount a container (200) that does not contain water in the second door (170), or mount a container (200) that contains a small amount of water in the second door (170).

[0269] In particular, when there is more water than the standard water level in the container (200) and there is no cover, if ice is supplied directly to the container (200), there is a risk that water may splash out of the container (200) during the process of supplying ice to the container (200).

[0270] That is, when the water level inside the container (200) is within the standard water level, it may be a case where there is almost no water, or where there is little risk of water splashing out of the container (200) even if ice is supplied while water is present.

[0271] Accordingly, if, as a result of the judgment in step S85, the water level in the container (200) is lower than the reference water level, ice can be automatically supplied to the container (200) up to the first level (first water level) (S86).

[0272] After ice is supplied up to the first level, water can be supplied to the container (200) up to the second level (second water level) (S89).

[0273] When water is supplied to the container (200), the water level inside the container (200) increases, and when the second level is detected by the ultrasonic sensor, the operation of the valve (302) can be stopped.

[0274] On the other hand, if the water level in the container (200) is above the reference water level as a result of the judgment in step S85, it can be determined whether the water level in the container (200) is above the first water level (S87).

[0275] If, as a result of the judgment in step S85, the water level in the container (200) is lower than the first water level, a set amount of ice can be supplied (S88). For example, if the ice discharge unit (135) operates for a predetermined operating time, a set amount of ice can be supplied to the container (200).

[0276] There may also be cases where the container (200) is mounted on the second door (170) while the user has already filled the container (200) with more water than the standard water level. In this case, since the user wants to add ice to the container (200) containing water, a set amount of ice can be supplied to the container (200).

[0277] After ice is supplied to the container (200), it can be determined whether the water level inside the container (200) has reached a second water level (S89).

[0278] In step S89, if the second level is detected by the ultrasonic sensor, the supply of ice water may be terminated.

[0279] On the other hand, if, as a result of the judgment in step S89, the second water level is not detected by the ultrasonic sensor, water may be additionally supplied to the container (200) until the second water level is detected by the ultrasonic sensor (S91).

[0280] Meanwhile, if, as a result of the judgment in step S87, the water level in the container (200) is greater than the first water level, ice may be additionally supplied to the container (200) until the second water level is detected by the ultrasonic sensor (S90).

[0281] When the water level in the container (200) is greater than the first water level, if a set amount of ice is supplied to the container (200), there may be a risk that the water will overflow from the container (200).

[0282] Therefore, at this time, ice can be additionally supplied to the container (200) until the second water level is detected by the ultrasonic sensor.

[0283] Accordingly, according to the present embodiment, even in the case of a container without a cover, the phenomenon of water splashing out of the container or overflowing during the process of supplying ice can be reduced.

[0284] Meanwhile, during the process of supplying water, ice, or ice water to the container (200), if the first water level is not detected by the water level detection sensor (410) during a standard time, there is a risk of water cutoff or failure of the valve (302), etc., so error information may be output from an output unit not shown.

[0285] FIG. 18 is a flowchart illustrating a method for supplying ice water to a container according to a third embodiment of the present invention.

[0286] In the case of this embodiment, a contact sensor or a non-contact sensor may be used as the water level detection sensor (410).

[0287] Referring to FIG. 18, the second door (170) can be opened to supply water and / or ice to the container (200) (S101).

[0288] With the second door (170) open, the container (200) can be mounted on the second door (170) (S102).

[0289] Next, the second door (170) can be closed (S103).

[0290] After the second door (170) equipped with the container (200) is closed, an ice water discharge command can be input through the first input unit (311) (S104).

[0291] Before or after the above ice water discharge command is input, the water level inside the container (200) can be detected by the water level detection sensor (410).

[0292] It can be determined whether the water level in the above container (200) is lower than the first water level (first level) (S105).

[0293] The user may mount a container (200) that does not contain water in the second door (170), or mount a container (200) that contains a small amount of water in the second door (170).

[0294] If, as a result of the judgment in step S105, the water level in the container (200) is within the first water level, water can be automatically supplied to the container (200) up to the first water level (S106).

[0295] After water is supplied up to the first level, ice can be supplied to the container (200) up to the second level (second level) (S107).

[0296] When ice is supplied to the container (200), the water level inside the container (200) increases, and when the second water level is detected by the water level detection sensor (410), the ice supply can be terminated.

[0297] On the other hand, if, as a result of judgment in step S105, the water level in the container (200) is above the first water level, ice can be supplied to the container (200) until the second water level is detected by the water level detection sensor (410) (S108).

[0298] That is, when the user fills the container (200) with water above the first level, only ice can be supplied to the container (200). Therefore, since additional water is not supplied to the container (200), the overflow of water from the container (200) can be reduced.

[0299] In addition to the above embodiments, this specification may further include the following embodiments.

[0300] 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).

[0301] 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).

[0302] The ice stored in the main ice bin can be supplied to the sub ice bin automatically or manually.

[0303] 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.

[0304] 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.

[0305] 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.

[0306] 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.

[0307] 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.

[0308] 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.

[0309] 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.

[0310] 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.

[0311] 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.

[0312] 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.
