[133] 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 surface or a rounded surface.

[134] A portion of the opening 252 may overlap the second extension 255 in a vertical direction. Another portion of the opening 252 may not overlap the second extension 255 in the vertical direction.

[135] FIG. 7 is a view schematically showing a cross-section taken along line 7-7 of FIG. 2.

[136] Referring to FIG. 7, the first door 100 may further include a path to guide ice discharged from the ice bin 134.

[137] The path may include a first ice duct 115 positioned at a lower side of the ice bin 134, and a second ice duct 116 to guide ice that has passed through the first ice duct 115 to the outlet 114. Ice in the ice bin 134 may be discharged to the first ice duct 115 by an operation of the ice discharge portion 135.

[138] The first door 100 may further include a cap duct 117 to open and close the first ice duct 115.

[139] The outlet 114 may include an ice outlet port 118 to discharge ice and a water outlet port 119 to discharge water.

[140] When the second door 170 on which the container 200 is mounted is closed, the ice outlet port 118 and the water outlet port 119 may be aligned with the opening 252 of the container 200. Accordingly, ice discharged from the ice outlet port 118 and / or water discharged from the water outlet port 119 may be supplied into the container 200 through the opening 252.

[141] As another example, the opening 252 may include an ice opening to allow ice to pass therethrough and a water opening to allow water to pass therethrough.

[142] The level sensor 410 may be in contact with the container 200, in a state in which the second door 170 on which the container 200 is mounted is closed.

[143] For example, the level sensor 410 may be a contact-type sensor. As an example, the level sensor 410 may be a contact-type capacitive sensor.

[144] The level sensor 410 may include a first sensor 411. The first sensor 411 may be in contact with a first portion of the container body 210. The first portion of the container body 210 may be a portion for detecting a first water level (a first level or a first height) H1 of the container body 210.

[145] The level sensor 410 may further include a second sensor 412. The first sensor 411 and the second sensor 412 may be disposed at different heights from each other.

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

[147] In the container body 210, water (ice or ice and water) or air may be positioned at the same height as the first portion. Since air and water have different dielectric constants, the water level can be distinguished by a difference in dielectric constants between air and water. That is, when it is detected that water is supplied to the same height as the first portion in the container body 210, it may be recognized that a first water level has been detected.

[148] In the container body 210, water (ice or ice and water) or air may be positioned at the same height as the second portion. When it is detected that water is supplied to the same height as the second portion in the container body 210, it may be recognized that a second water level has been detected.

[149] At this time, to prevent water from overflowing to the outside of the container 200, the second water level may be set to a height lower than a lower end of the extension 253.

[150] The first water level may be a reference level at which water can be primarily supplied when water is supplied.

[151] The second water level may be a limit level for preventing water or ice from being supplied any further. That is, water, ice, or water and ice may be supplied up to the second water level within the container. Although not limited thereto, the second water level may be a water level of a portion lower than a lower end of the extension.

[152] FIG. 8 is a view schematically showing various examples of a mounting detection sensor for detecting a mounting of a container.

[153] Referring to (a) of FIG. 8, the container 200 includes a magnet 421, and the mounting detection sensor 420 may be a Hall sensor to detect a magnetism of the magnet 421.

[154] The mounting detection sensor 420 may be disposed, for example, on the second door 170 or the container mounting portion 180. However, in a case in which he mounting detection sensor 420 is disposed on the container mounting portion 180, a wire connected to the mounting detection sensor 420 may be guided to the second door 170.

[155] Alternatively, a mounting detection sensor 420a, which is a Hall sensor, may be disposed 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, in the dispenser housing 112.

[156] As another example, referring to (b) of FIG. 8, the mounting detection sensor 422 may be an ultrasonic sensor. The mounting detection sensor 422 may be installed on the second door 170 or the first door 100. In a case in which the ultrasonic sensor is installed on the first door 100, mounting of the container 200 may be detected after the second door 170 is closed. In a case in which the ultrasonic sensor is installed on the second door 170, mounting of the container 200 may be detected at the time the container 200 is mounted.

[157] As another example, referring to (c) of FIG. 8, the mounting detection sensor 423 may be an optical sensor. The optical sensor may include a light-emitting part 423a and a light-receiving part 423b.

[158] Positions of the light-emitting part 423a and the light-receiving part 423b may be determined to allow the container 200 to be positioned between the light-emitting part 423a and the light-receiving part 423b.

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

[160] Alternatively, the light-emitting part 423a and the light-receiving part 423b may be provided on the second door 170 or the container mounting portion 180.

[161] Alternatively, one of the light-emitting part 423a and the light-receiving part 423b may be disposed on the first door 100, and the other of the light-emitting part 423a and the light-receiving part 423b may be disposed on the second door 170.

[162] As another example, referring to (d) of FIG. 8, the mounting detection sensor 424 may be a micro switch to be turned on or off by being pressed by the container.

[163] The micro switch may be disposed on the container mounting portion 180 or the second door 170. Alternatively, the micro switch may be disposed on 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.

[164] Hereinafter, a process to supply water and / or ice to the container 200 will be described.

[165] FIG. 9 is a flowchart for explaining a first method of supplying water and ice to a container of the present invention.

[166] Referring to FIG. 9, a first method is a method in which water and ice are supplied to a container by an input of a water and ice discharge command by a user (manual mode).

[167] To supply water and / or ice to the container 200, the second door 170 may be opened (S1).

[168] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S2).

[169] Then, the second door 170 may be closed (S3).

[170] After the second door 170 in which the container 200 is mounted is closed, an ice and water discharge command may be input through the first input portion 311 (S4).

[171] When the water and ice discharge command is input, water may be supplied to the container 200 as much as the first level (S5). That is, the valve 302 is opened, water is supplied to the container 200, and when the first level is detected by the first sensor 411, the valve 302 may be closed.

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

[173] As an example, the ice discharge portion 135 may operate to discharge ice from the ice bin 134. The ice discharged from the ice bin 134 may pass through an ice duct 115 and 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.

[174] When ice 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, an operation of the ice discharge portion 135 may be stopped.

[175] Therefore, according to the present embodiment, the water and ice may be supplied up to the second level in the container 200.

[176] According to the present embodiment, since water and ice can be supplied together to the container, there is an advantage that a user can drink water containing ice.

[177] Since the second level is a water level of a portion lower than the extension 253, the extension 253 may not be submerged in water or the ice may be prevented from interfering with the extension 253. Accordingly, water may be prevented from overflowing to the outside of the container 200.

[178] FIG. 10 is a flowchart for explaining a second method of supplying water and ice to a container of the present invention.

[179] Referring to FIG. 10, a second method is a method in which water and ice are supplied to a container by an input of a water and ice discharge command by a user (manual mode).

[180] To supply water and / or ice to the container 200, the second door 170 may be opened (S11).

[181] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S12).

[182] Then, a water and ice discharge command may be input through the first input portion 311 or the second input portion 312 (S13). In a state in which the second door 170 is opened, a user can easily access the second input portion 312, so the water and ice discharge command can be input through the second input portion 312. It is also possible to input a command using the first input portion 311.

[183] After the water and ice discharge command is input, the second door 170 may be closed (S14).

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

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

[186] As described above, the ice discharge portion 135 may operate to discharge ice from the ice bin 134. The ice discharged from the ice bin 134 may pass through an ice duct 115 and 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.

[187] When ice 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, an operation of the ice discharge portion 135 may be stopped.

[188] FIG. 11 is a flowchart for explaining a modified example of the first method of supplying water and ice to a container of the present invention.

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

[190] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S22).

[191] Then, the second door 170 may be closed (S23).

[192] After the second door 170 in which the container 200 is mounted is closed, a water and ice discharge command may be input through the first input portion 311 (S24).

[193] When the water and ice discharge command is input, water may be supplied to the container 200 as much as the first level (S25). That is, the valve 302 is opened, water is supplied to the container 200, and when the first level is detected by the first sensor 411, the valve 302 may be closed.

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

[195] As an example, the ice discharge portion 135 may operate to discharge ice from the ice bin 134. The ice discharged from the ice bin 134 may pass through an ice duct 115 and 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, an operation time of the ice discharge portion 135 may be predetermined.

[196] That is, when the ice discharge portion 135 operates for a predetermined operation time, a set amount of ice may be supplied to the container 200.

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

[198] As a result of the determination in step S27, when the second level is detected by the second sensor 412, the supply of the water and ice may be ended.

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

[200] FIG. 12 is a flowchart for explaining a third method of supplying water and ice to a container of the present invention.

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

[202] To supply water and / or ice to the container 200, the second door 170 may be opened (S31).

[203] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S32).

[204] Then, the second door 170 may be closed (S33).

[205] When the second door 170 in which the container 200 is mounted is closed, water may be automatically supplied to the container 200 as much as the first level (S34). That is, even without a user inputting a separate water and ice discharge command, water may be automatically supplied to the container 200 when the second door 170 is closed.

[206] The valve 302 is opened, water is supplied to the container 200, and when the first level is detected by the first sensor 411, the valve 302 may be closed.

[207] After water is supplied up to the first level, ice may be supplied to the container 200 up to the second level (S35). As an example, the ice discharge portion 135 may operate to discharge ice from the ice bin 134. The ice discharged from the ice bin 134 may pass through an ice duct 115 and 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.

[208] When ice 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 ice discharge portion 135 may be stopped.

[209] Therefore, according to the present embodiment, there is an advantage that water and ice can be supplied to the container 200 even without a user's command input.

[210] FIG. 13 is a flowchart for explaining a modified example of a third method of supplying water and ice to a container of the present invention.

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

[212] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S42).

[213] Then, the second door 170 may be closed (S43).

[214] When the second door 170 in which the container 200 is mounted is closed, ice may be automatically supplied to the container 200 as much as a first level (S44). Alternatively, a set amount of ice may be supplied to the container 200.

[215] That is, even without a user inputting a separate water and ice discharge command, ice may be automatically supplied to the container 200 when the second door 170 is closed.

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

[217] When water is supplied to the container 200, a 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 may be stopped.

[218] FIG. 14 is a flowchart for explaining a fourth method of supplying water to a container of the present invention.

[219] Referring to FIG. 14, a fourth method is a method for a user to additionally supply water or ice after water is automatically supplied as much as a first level.

[220] To supply water and / or ice to the container 200, the second door 170 may be opened (S51).

[221] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S52).

[222] Then, the second door 170 may be closed (S53).

[223] When the second door 170 in which the container 200 is mounted is closed, water may be automatically supplied to the container 200 as much as the first level (S54).

[224] That is, even without a user inputting a separate water discharge command, water may be automatically supplied to the container 200 when the second door 170 is closed.

[225] After water is supplied up to the first level, it may be determined whether the water discharge command has been input through the first input portion 311 (S55).

[226] As a result of the determination in step S55, when it is determined that the water discharge command has been input, the water may be supplied to the container 200 up to the second level (S56).

[227] On the other hand, as a result of the determination in step S55, when it is determined that the water discharge command has not been input, it may be determined whether an ice discharge command has been input (S57).

[228] As a result of the determination in step S57, when it is determined that the ice discharge command has been input, ice may be supplied to the container 200 until the second level is detected (S58).

[229] In the case of the present embodiment, when the second door 170 is closed, water may be automatically supplied to the container 200 up to the first level, and thereafter, water or ice may be additionally supplied to the container 200 by a user's selection.

[230] FIG. 15 is a flowchart for explaining a fifth method of supplying at least one of water or ice to a container of the present invention.

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

[232] To supply water and / or ice to the container 200, the second door 170 may be opened (S61).

[233] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S62).

[234] Then, the second door 170 may be closed (S63).

[235] When the second door 170 in which the container 200 is mounted is closed, it may be determined whether a water discharge command has been input (S64).

[236] As a result of the determination in step S64, when it is determined that the water discharge command has been input, water may be supplied to the container 200 as much as a reference level (S65).

[237] The reference level may be set to a first level by a user's selection or automatically, and may be changed to a second level.

[238] As a result of the determination in step S64, when it is determined that the water discharge command has not been input, it may be determined whether an ice discharge command has been input (S66).

[239] As a result of the determination in step S66, when it is determined that the ice discharge command has been input, ice may be supplied to the container 200 as much as a reference height (S67). Alternatively, when it is determined that the ice discharge command has been input, a set amount of ice may be supplied to the container 200. The reference height may be set to a first height by a user's selection or automatically, and may be changed to a second level.

[240] As a result of the determination in step S66, when it is determined that the ice discharge command has not been input, it may be determined whether a water and ice discharge command has been input (S68).

[241] As a result of the determination in step S68, when it is determined that the water and ice discharge command has been input, water may be supplied to the container 200 up to the first level (S69). Then, ice may be supplied to the container 200 until the second level is detected (S70).

[242] In the present embodiment, it is also possible that the order of step S69 and step S70 is reversed.

[243] Meanwhile, in a state in which the second door 170 is opened, a user may place the container 200 or a cup of another shape in the space 113 of the dispenser housing 112 and then input any one of a water discharge command, an ice discharge command, and a water and ice discharge command through the second input portion 312.

[244] When the water discharge command is input through the second input portion 312, water may be supplied to the container 200 up to the reference level, and the reference level is changeable.

[245] When an ice discharge command is input through the second input portion 312, ice may be supplied to the container 200 up to the reference height, and the reference height is changeable.

[246] When a water and ice discharge command is input through the second input portion 312, water may be supplied to the container 200 as much as the first level, and then ice may be supplied to the container 200 until the second level is detected. Of course, the supply order of water and ice may be reversed.

[247] Meanwhile, in the present embodiment, when the container is not detected by the mounting detection sensor 420, discharge of water and / or ice is not performed, and information on the non mounting of the container may be output through an output portion (a speaker or a display) not shown.

[248] FIG. 16 is a view showing a positional relationship between a level sensor and a container according to a second embodiment of the present invention.

[249] This embodiment is identical to the previous embodiment in other portions, except that it differs in the type and arrangement of the level sensor. Therefore, hereinafter, only the characteristic portions of the present embodiment will be described.

[250] Referring to FIG. 16, a level sensor 413 of the present embodiment may be, for example, an ultrasonic sensor.

[251] The ultrasonic sensor may be positioned above the container 200. For example, the ultrasonic sensor may be positioned on the second door 170 or on the first door 100.

[252] In either case, the ultrasonic sensor may be aligned with the opening 252 of the container 200. In a case in which the ultrasonic sensor is positioned on the first door 100, the ultrasonic sensor may be aligned with the opening 252 of the container 200 when the second door 170 on which the container 200 is mounted is closed.

[253] On the other hand, in a case in which the ultrasonic sensor is positioned on the second door 170, the ultrasonic sensor may be aligned with the opening 252 of the container 200 when the container 200 is mounted on the container mounting portion 180. To prevent ultrasonic waves from interfering with the extension 253, the ultrasonic sensor may be non-overlapping with the extension 253 on the cover 250.

[254] By using the ultrasonic sensor, it is possible to detect the water level by measuring a distance from the ultrasonic sensor to a water surface. In particular, using the ultrasonic sensor allows not only the detection of a specific water level but also the detection of changes in the water level.

[255] That is, by using the ultrasonic sensor, the detection of a first water level (first level) and a second water level (second level) is possible.

[256] As another example, a separate sensing hole may be formed in the cover 250, making it possible for the ultrasonic sensor to be aligned with the sensing hole of the container 200. In this case, the sensing hole may be disposed spaced apart from the opening and may be formed to have a diameter less than a diameter of the opening 252. Therefore, while water level detection is possible through the sensing hole, it is possible to restrict water from overflowing to the outside of the container through the sensing hole.

[257] Even when the ultrasonic sensor is used, the first to third methods and modifications for supplying water and ice to the container described above can be applied as they are.

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

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

[260] Various containers may be mounted on the second door 170. Accordingly, the container 200 referred to below may be a container from which a cover is separated, a container in which a cover does not exist, or a container in which a cover is mounted.

[261] To supply water and / or ice to the container 200, the second door 170 may be opened (S81).

[262] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S82).

[263] Then, the second door 170 may be closed (S83).

[264] After the second door 170 in which the container 200 is mounted is closed, a water and ice discharge command may be input through the first input portion 311 (S84).

[265] Before or after the water and ice discharge command is input, a water level in the container 200 may be detected by the ultrasonic sensor.

[266] It may be determined whether a water level in the container 200 is within a reference level (S85).

[267] The reference level may be a water level lower than the first level, and may include a case where the water level is zero.

[268] A user may mount the container 200 in which water does not exist on the second door 170, or may mount the container 200 in which a small amount of water exists on the second door 170.

[269] Particularly, in a case in which more water than the reference level exists in the container 200 and a cover does not exist, if ice is directly supplied to the container 200, there is a concern that water may splash to an outside of the container 200 in a process in which the ice is supplied to the container 200.

[270] That is, a case in which the water level in the container 200 is within the reference level may be a case in which water hardly exists, or a case in which there is little concern that water splashes to the outside of the container 200 even if ice is supplied in a state in which water exists.

[271] Therefore, as a result of the determination in step (S85), when a water level in the container 200 is less than the reference level, ice may be automatically supplied to the container 200 as much as a first level (first water level) (S86).

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

[273] When water is supplied to the container 200, a water level in the container 200 increases, and when the second level is detected by the ultrasonic sensor, the operation of the valve 302 may be stopped.

[274] On the other hand, as a result of the determination in step S85, when the water level in the container 200 is equal to or greater than the reference level, it may be determined whether the water level in the container 200 is equal to or greater than the first level (S87).

[275] As a result of the determination in step S87, when the water level in the container 200 is less than the first level, a set amount of ice may be supplied (S88). As an example, when the ice discharge portion 135 operates for a predetermined operation time, the set amount of ice may be supplied to the container 200.

[276] There may also be a case where the container 200 is mounted on the second door 170 in a state in which a user has already filled the container 200 with more water than the reference level. In this case, since the user intends to add ice to the container 200 containing water, a set amount of ice may be supplied to the container 200.

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

[278] As a result of the determination in step S89, when the second level is detected by the ultrasonic sensor, the supply of the ice water may be ended.

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

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

[281] When the water level in the container 200 is greater than the first level, if a set amount of ice is supplied to the container 200, there may be a concern that water overflows from the container 200.

[282] Therefore, at this time, ice may be additionally supplied to the container 200 until the second level is detected by the ultrasonic sensor.

[283] Therefore, according to the present embodiment, even in a case of a container in which a cover does not exist, a phenomenon in which water splashes or overflows to the outside of the container in a process of supplying ice can be reduced.

[284] Meanwhile, in a process in which water, ice, or water and ice are supplied to the container 200, if the first level is not detected by the level sensor 410 during a reference time, there is a concern of a water outage or a failure of the valve 302, and thus error information may be output from an output portion not shown.

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

[286] In the case of the present embodiment, a contact type sensor or a non-contact type sensor may be used as the level sensor 410.

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

[288] In a state in which the second door 170 is opened, the container 200 may be mounted on the second door 170 (S102).

[289] Then, the second door 170 may be closed (S103).

[290] After the second door 170 in which the container 200 is mounted is closed, a water and ice discharge command may be input through the first input portion 311 (S104).

[291] Before or after the water and ice discharge command is input, a water level in the container 200 may be detected by the level sensor 410.

[292] It may be determined whether a water level in the container 200 is less than a first level (first water level) (S105).

[293] A user may mount the container 200 in which water does not exist on the second door 170, or may mount the container 200 in which a small amount of water exists on the second door 170.

[294] As a result of the determination in step S105, when a water level in the container 200 is within a first level, water may be automatically supplied to the container 200 as much as the first level (S106).

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

[296] When ice is supplied to the container 200, a water level in the container 200 increases, and when the second level is detected by the level sensor 410, the supply of ice may be ended.

[297] On the other hand, as a result of the determination in step S105, when the water level in the container 200 is equal to or greater than the first level, ice may be supplied to the container 200 until the second level is detected by the level sensor 410 (S108).

[298] That is, when a user puts water of the first level or more in the container 200, only ice may be supplied to the container 200. Accordingly, since water is not additionally supplied to the container 200, overflowing of water from the container 200 can be reduced.

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

[300] In another embodiment, in addition to an ice bin in which ice made in an icemaker is stored, the container may also serve as an ice bin. For example, the ice bin positioned in the ice making chamber may be a main ice bin (or a first ice bin), and the container may be a sub ice bin (or a second ice bin).

[301] In a state in which the second door 170 is closed, ice stored in the main ice bin may be discharged from the main ice bin and supplied to the sub ice bin by an operation of the ice discharge portion 135. Accordingly, the ice may be stored in the sub ice bin. In this state, water may be supplied to the sub ice bin according to a user's selection. An amount of ice stored in the sub ice bin may be determined based on a level detected by the level sensor 410 or may be determined by an operation time of the ice discharge portion 135.

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

[303] For example, when the main ice bin is detected to be full, the ice stored in the main ice bin may be supplied to the sub ice bin.

[304] Alternatively, when a non-operation time of the ice discharge portion 135 within the main ice bin becomes greater than or equal to a reference time, the ice stored in the main ice bin may be supplied to the sub ice bin.

[305] Alternatively, the ice stored in the main ice bin may be supplied to the sub ice bin based on a pattern in which ice is discharged from the main ice bin, for example, based on a user’s ice usage pattern. The user’s ice usage pattern may be stored in a memory (not shown). For example, the ice stored in the main ice bin may be supplied to the sub ice bin at a specific time range, a specific date, or a specific day of the week. Alternatively, the ice stored in the main ice bin may be supplied to the sub ice bin at a time range, date, or day of the week set by the user.

[306] Alternatively, when the user selects a sub ice bin mode through an input portion, the ice stored in the main ice bin may be supplied to the sub ice bin.

[307] In another embodiment, the container may also serve as an ice bin independently of an ice bin in which ice made in an ice maker is stored. For example, the ice bin positioned in the ice making chamber may be a first ice bin, and the container may be a second ice bin.

[308] At this time, although not shown, an independent path for directly moving the ice generated in the ice maker to the second ice bin may be provided in the first door.

[309] Accordingly, the ice generated in the ice maker may be stored in the first ice bin or may be stored in the second ice bin through a separate path. The ice stored in the first ice bin may be guided to the ice outlet port through a first path. A second path may guide the ice generated in the ice maker to the ice outlet port.

[310] Alternatively, when ice separation is performed by the ice maker, some of the ice generated in the ice maker may be stored in the first ice bin, and the other portion may be stored in a separate second path for the second ice bin. When the second path is opened, the ice may be supplied to the second ice bin.

[311] Alternatively, it is also possible for the ice maker to include a first ice maker for the first ice bin and a second ice maker for the second ice bin.

[312] Alternatively, it is also possible for the ice bin provided in the ice making chamber to be omitted. In this case, the ice generated in the ice maker may be stored on an ice path, and when the ice path is opened, it is also possible for the ice to be supplied to the container.
