[0148] The second door (170) may include a container mounting portion (180) on which a container (200) is seated. The container mounting portion (180) may be coupled to the rear side of the second door (170). When the container (200) is mounted on the container mounting portion (180) and the second door (170) is closed, the container (200) and the container mounting portion (180) may be positioned in the space (113). When the second door (170) is closed, the container (200) may be aligned vertically with the discharge portion (114).

[0149] As another example, it is also possible for the container mounting part (180) to be formed integrally with the second door (170).

[0150] The bottom of the container mounting portion (180) may be positioned higher than the bottom (112a) of the dispenser housing (112). Thus, when the second door (170) is closed, interference between the container mounting portion (180) and the dispenser housing (112) can be prevented.

[0151] With the container (200) mounted on the container mounting portion (180), the upper surface of the container (200) may be positioned lower than the discharge portion (114). Therefore, when the second door (170) is closed, interference between the container (200) and the dispenser housing (112) can be prevented. When the second door (170) is closed, the container (200) may be positioned below the discharge portion (114).

[0152] The second door (170) can cover the storage space (120). A basket (172) can be attached to the rear side of the second door (170). When the second door (170) is closed, the basket (172) can be positioned in the storage space (120).

[0153] The above refrigerator (1) may further include an input unit (310). Through the input unit (310), a water discharge command, an ice discharge command, and an ice water discharge command can be input.

[0154] Through the above input unit (310), the shape of the ice to be discharged, for example, crushed ice or cubed ice, can be selected.

[0155] Through the input unit (310), the amount of water and / or the amount of ice to be discharged can be selected. When ice water is discharged, the ratio of ice to water can be selected through the input unit (310).

[0156] Through the input unit (310), a manual mode or an automatic mode can be selected. The manual mode is a mode in which water and / or ice is discharged through the dispenser (110) by the input of a user's command. The automatic mode is a mode in which water and / or ice is automatically discharged through the dispenser (110) when a set condition is satisfied.

[0157] The input unit (310) may be provided in one or more of the first door (100) and the second door (170). Alternatively, the input unit (310) may include a first input unit capable of inputting some commands among all commands and a second input unit capable of inputting some commands among all commands. The first input unit may be provided in the first door (100), and the second input unit may be provided in the second door (170).

[0158] At this time, the commands that can be entered in the first input unit may be the same as or different from the commands that can be entered in the second input unit. Some of the commands that can be entered in the first input unit may be the same as some of the commands that can be entered in the second input unit.

[0159] The refrigerator (1) may further include a water level detection sensor (410) for detecting the water level of a container (200). The water level detection sensor (410) may be placed in one or more of the first door (100) and the second door (170).

[0160] For example, the container (200) may include a magnet, and the mounting detection sensor (420) may be a Hall sensor that detects the magnetism of the magnet. 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).

[0161] As another example, a mounting detection sensor (420), 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 (420) may detect the magnet (421) of the container (200). The mounting detection sensor (420) may be installed, for example, on the dispenser housing (112).

[0162] As another example, the mounting detection sensor (420) may be an ultrasonic sensor. The mounting detection sensor (420) 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.

[0163] As another example, the mounting detection sensor (420) may be a light sensor. The light sensor may include a light-emitting part and a light-receiving part. The positions of the light-emitting part and the light-receiving part may be determined such that the container (200) is positioned between the light-emitting part and the light-receiving part. For example, the light-emitting part and the light-receiving part 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). Alternatively, the light-emitting part and the light-receiving part may be provided in the second door (170) or the container mounting part (180). Alternatively, either the light-emitting part or the light-receiving part may be placed in the first door (100) and the other may be placed in the second door (170).

[0164] As another example, the mounting detection sensor (420) may be a micro switch that is turned on or off by being pressed by the container. The micro switch may be placed in the container mounting part (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.

[0165] Although not illustrated, the refrigerator (1) may further include a leak detection sensor. The leak detection sensor is provided in the dispenser housing (112) and can detect a certain amount of water that has fallen to the bottom of the dispenser housing (112).

[0166] The above refrigerator (1) can receive water from a water source (321).

[0167] The above water source (321) may be a faucet or a supply tank connected to the refrigerator (1).

[0168] The refrigerator (1) may further include a water flow (330) through which water supplied from the water source (321) flows.

[0169] The refrigerator (1) may further include a water supply valve (322). When the water supply valve (322) is opened, water supplied from the water source (321) can flow through the water path (330).

[0170] The refrigerator (1) may further include a flow sensor (323). The flow sensor (323) can measure the amount of water flowing through the water path (330).

[0171] A portion of the water passage (330) may be located in the cabinet (10) and another portion may be located in the door (20). In this embodiment, the other portion of the water passage (330) is described as being located in the refrigerator door (21). In this case, the water passage (330) may pass through the hinge of the first door (100), but is not limited thereto.

[0172] The refrigerator (1) may further include a filter (325) for purifying water. In this embodiment, the filter (325) may be located, for example, on the refrigerator door (21).

[0173] The filter (325) may be located, for example, at the lower side of the ice-making room (130). The filter (325) may be located on the refrigerator door (21) with its length arranged in a left-right direction. The filter (325) may be located on the upper side of the dispenser housing (112). For example, the filter (325) may be located on the first door (100).

[0174] The refrigerator (1) may further include a water tank (326) in which water purified by the filter (325) is stored. The water tank (326) may be placed in the refrigerator door (21). For example, the water tank (326) may be located in the first door (100).

[0175] The refrigerator (1) may further include a first valve (303). The first valve (303) can control the flow of water discharged from the dispenser (110).

[0176] The refrigerator (1) may further include a second valve (304). The second valve (304) can regulate the flow of water supplied to the ice maker (132). The first valve (303) and the second valve (304) may be placed on the refrigerator door (21). For example, the first valve (303) and the second valve (304) may be located on the first door (100).

[0177] For example, a single three-way valve can control the flow of water supplied to the dispenser (110) and / or the ice maker (132).

[0178] FIG. 9 is a perspective view of a container according to a first embodiment of the present invention, and FIG. 10 is a cross-sectional view taken along 10-10 of FIG. 9.

[0179] Referring to FIGS. 9 and FIGS. 10, 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).

[0180] 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).

[0181] 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).

[0182] 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.

[0183] The above cover (250) may include an opening (252).

[0184] The opening (252) can provide a passage for water and ice. That is, when the second door (170) equipped with the container (200) is closed, water or ice discharged from the dispenser (110) can be supplied into the container (200) through the opening (252).

[0185] The diameter of the opening (252) may be larger than the diameter of the ice.

[0186] The above cover (250) may further include an extension (253). The extension (253) may extend downward from the lower surface of the cover (250). The extension (253) may change the direction of movement of the supplied water or ice.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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).

[0191] 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.

[0192] 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.

[0193] FIG. 11 is a schematic drawing showing a cross-section cut along 11-11 of FIG. 2. FIG. 12 is a schematic drawing showing a cross-section cut along 12-12 of FIG. 1.

[0194] Referring to FIGS. 5, FIGS. 11 and FIGS. 12, the first door (100) may further include a passage for guiding ice discharged from the ice bin (134).

[0195] 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).

[0196] The first door (100) may further include a cap duct (117) for opening and closing the first ice duct (115).

[0197] 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.

[0198] 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) (see solid line) and water discharged from the water discharge port (119) (see dotted line) can be supplied into the container (200) through the opening (252).

[0199] The diameter of the opening (252) may be larger than the diameter of the ice discharge port (118). The diameter of the opening (252) may be larger than the sum of the diameter of the ice discharge port (118) and the diameter of the water discharge port (119).

[0200] In order to prevent ice from splashing out of the container (200) during the process of supplying ice to the container (200) through the opening (252), the difference between the diameter of the opening (252) and the diameter of the ice discharge port (118) may be equal to or smaller than the radius of the ice discharge port (118). The horizontal distance (distance in the Y-axis direction) between the end adjacent to the lever (111) (or the rear wall of the dispenser housing (112)) at the opening (252) and the end adjacent to the lever (111) (or the rear wall of the dispenser housing (112)) at the ice discharge port (118) may be equal to or smaller than the radius of the ice discharge port (118). The horizontal distance (distance in the Y-axis direction) between the end adjacent to the lever (111) (or the rear wall of the dispenser housing (112)) at the opening (252) and the end adjacent to the lever (111) (or the rear wall of the dispenser housing (112)) at the ice discharge port (118) may be equal to or smaller than the diameter of the water discharge port (119).

[0201] In order to prevent ice from splashing out of the container (200) during the process of supplying ice to the container (200) through the opening (252), it is advantageous to have a small vertical gap (Z-axis direction gap) between the bottom of the ice discharge port (118) and the opening (252). Furthermore, having a small vertical gap (Z-axis direction gap) between the bottom of the ice discharge port (118) and the opening (252) is advantageous in terms of increasing the volume (water storage capacity) of the container (200). Of course, even if the second door (170) is closed while the container (200) is mounted in an inclined state on the container mounting part (200), the bottom of the ice discharge port (118) must be spaced apart from the container (200) by a certain distance so that the container (200) does not interfere with the ice discharge port (118) or the water discharge port (119).

[0202] For example, the vertical distance (distance in the Z-axis direction) between the bottom of the ice discharge port (118) and the opening (252) may be equal to or smaller than the radius of the ice discharge port (118). The vertical distance between the bottom of the ice discharge port (118) and the opening (252) may be equal to or smaller than the diameter of the water discharge port (119). The vertical distance between the bottom of the ice discharge port (118) and the opening (252) may be equal to or smaller than the difference between the diameter of the opening (252) and the diameter of the ice discharge port (118).

[0203] The positional relationship between the opening (252) and surrounding structures mentioned above may be applied in the same or similar way to the positional relationship between the upper opening of the container body (210) and surrounding structures.

[0204] In terms of increasing the volume of the container (200), some walls of the container (200) may be positioned closer to the lever (111) than to the ice discharge port (118) based on the horizontal direction (Y-axis direction).

[0205] A portion of the wall of the container (200) may be, for example, a connecting wall to which the lower side of the handle (230) is connected, or a wall located below the connecting wall. A portion of the wall of the container (200) may be, for example, a connecting wall to which the upper side of the handle (230) is connected, or a wall located above the connecting wall.

[0206] 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. In this case, the diameter of the ice opening may be larger than the diameter of the ice discharge port (118).

[0207] When the second door (170) on which the container (200) is mounted is closed, the handle (230) of the container (200) may be positioned to face the lever (111). The handle (230) (or part of the container (200)) may be spaced apart from the lever (111). When the handle (230) is spaced apart from the lever (111), the phenomenon of the handle (230) pressing against the lever (111) can be prevented. That is, the handle (230) may be spaced apart from the lever (111) regardless of the position of the container (200) in the container mounting part (180). With the second door (170) closed, the handle (230) can be separated from the lever (111) while the container (200) is in contact with the vertical wall adjacent to the lever (111) in the container mounting part (180).

[0208] When the second door (170) equipped with the container (200) is closed, at least a portion of the container (200) may overlap with the storage space (120) in the vertical direction.

[0209] When the second door (170) equipped with the container (200) is closed, at least a portion of the opening (252) of the container (200) may overlap with the storage space (120) in the vertical direction.

[0210] 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.

[0211] When the second door (170) equipped with the container (200) is closed, at least a portion of the container (200) may overlap with the ice-making chamber (130) in the vertical direction.

[0212] When the second door (170) equipped with the container (200) is closed, at least a portion of the container (200) may overlap vertically with one or more of the ice maker (132) and the ice bin (134).

[0213] 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.

[0214] 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).

[0215] 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).

[0216] Meanwhile, at least a portion of the filter (325) may be located below the ice bin (134). At least a portion of the filter (325) may overlap with the ice bin (134) in the vertical direction (Z-axis direction).

[0217] The filter (325) may be located below the ice maker (132). At least a portion of the filter (325) may overlap with the ice maker (132) in the vertical direction.

[0218] The filter (325) may be superimposed on one or more of the first ice duct (115) and the second ice duct (116) in a horizontal direction (e.g., front-back direction) (Y-axis direction).

[0219] The X-axis direction is a direction that intersects the Z-axis and Y-axis directions, and can be, for example, the left-right direction.

[0220] Referring to FIG. 12, a first component may be placed on one side of the dispenser housing (112) (or space 133)) with respect to the X-axis direction, and a second component may be placed on the other side.

[0221] For example, the first part may include a cold air duct (500).

[0222] The second part may include one or more of a water tank (326), a filter (325), a first valve (303), and a second valve (304).

[0223] When the second door (170) equipped with the container (200) is closed, at least a portion of the container (200) may overlap horizontally (in the X-axis direction) with one or more of the first and second parts.

[0224] FIG. 12 illustrates, for example, that the cold air duct (500) is located on one side of the dispenser housing (112) and the water tank (326) is located on the other side of the dispenser housing (112).

[0225] The water tank (326) can be positioned lower than the filter (325).

[0226] At least a portion of the above cold air duct (500) may overlap with the dispenser housing (112) and the water tank (326) in the left-right direction (X-axis direction).

[0227] The above cold air duct (500) may be connected to the ice-making room (130). The above cold air duct (500) may include a first duct (510) and a second duct (520). The first duct (510) may guide cold air introduced through the cold air inlet (101) to the ice-making room (130). The second duct (520) may guide cold air from the ice-making room (130) to the cold air outlet (102).

[0228] The first door (100) may include a door frame (103) that forms an internal insulation space. The door frame (103) and the dispenser housing (112) may form the insulation space. The insulation space may be filled with a foaming agent. When the foaming agent filled in the insulation space hardens, it may form an insulating material.

[0229] In the case of the present embodiment, if the water tank (326) is positioned on the opposite side of the cold air duct (500) with respect to the dispenser housing (112), interference between the water tank (326) and the cold air duct (500) is prevented, and the thickness of the insulation material formed within the insulation space is prevented. At this time, the water tank (326) and the filter (326) may be located in a separate receiving space partitioned from the insulation space, so that contact with the insulation material is prevented.

[0230] When the second door (170) equipped with the container (200) is closed, the container (200) can be positioned in the space (113). At least a portion of the container (200) can overlap with the dispenser housing (112) and the cold air duct (500) in the left-right direction (X-axis direction).

[0231] Based on the X-axis direction, at least a portion of the container (200) may be located between the water tank (326) and the cold air duct (500).

[0232] One or more of the first valve (303) and the second valve (304) may be located on the opposite side of the cold air duct (500) relative to the dispenser housing (112).

[0233] Alternatively, the positions of the filter (325) and the water tank (326) may be opposite to each other. That is, it is possible for the filter (325) to be located on the opposite side of the cold air duct (500) relative to the dispenser housing (112), and for the water tank (326) to be located on the lower side of the ice bin (134).

[0234] The above water tank (326) may be a container type that stores water in an internal space, or a tube type in which a tube is wound multiple times. In either case, the above water tank (326) may be placed on the refrigerator door (21).

[0235] In this embodiment, when the filter (325) is placed on the refrigerator door (21), there is an advantage that the filter (325) can be easily replaced.

[0236] In the above embodiment, the water level detection sensor (410) was described as a contact type sensor, but alternatively, the water level detection sensor (410) may be an ultrasonic sensor.

[0237] 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). In either case, the ultrasonic sensor may be aligned with the opening (252) of the container (200). When the ultrasonic sensor is located 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. On the other hand, when the ultrasonic sensor is located 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 part (180). In order to prevent the ultrasonic waves from interfering with the extension (253), the ultrasonic sensor may not overlap with the extension (253) in the cover (250).

[0238] 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.

[0239] 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.

[0240] Below, the process of supplying water and / or ice to the above container (200) will be described.

[0241] 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.

[0242] 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.

[0243] 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).

[0244] 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.

[0245] Alternatively, if automatic mode is selected, when the second door (170) is closed, water and / or ice may 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 may be selected through the input unit (310). In addition, in the case of ice water, the ratio of water to ice may be selected through the input unit (310).

[0246] 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).

[0247] 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.

[0248] When ice is supplied along with water, the temperature of the water is lowered compared to when only water is supplied to the container, allowing for the consumption of cooler water.

[0249] FIG. 11 is a drawing showing a water supply path according to a second embodiment of the present invention.

[0250] This embodiment is identical to the first embodiment in other respects, except that one or more additional ice makers are provided in the cabinet (10). Below, only the characteristic parts of this embodiment will be described, and the same reference numerals will be used for components identical to the first embodiment.

[0251] Referring to FIG. 13, the water channel (300) according to the second embodiment may include a first channel (331) and a second channel (332).

[0252] The first Euro (331) is a path that passes through the hinge (340) of the first door (100) and is guided from the cabinet (10) to the refrigerator door (21).

[0253] The second Euro (332) is a path that passes through the hinge (340) of the first door (100) and is guided from the refrigerator door (21) to the cabinet (10).

[0254] The above water channel (300) may further include a door channel (333). The filter (325) and the water tank (326) may be provided in the door channel (333).

[0255] The above door passage (333) can be branched into two passages by a connector (327). A first valve (303) and a second valve (304) can be connected to one passage. The second passage (332) can be connected to the other passage.

[0256] The cabinet (10) may be equipped with one or more of a first main body ice maker (341) that produces first ice and a second main body ice maker (342) that produces second ice.

[0257] The first ice and the second ice may be of the same type (form) or different types (forms).

[0258] One or more of the first body valve (305) for the first body ice maker (341) and the second body valve (306) for the second body ice maker (342) may be connected to the second Euro (332).

[0259] FIG. 14 is a drawing showing a water flow path according to a third embodiment of the present invention.

[0260] This embodiment is identical to the first embodiment in other respects, and differs in that the position of the filter is different. Therefore, the characteristic parts of this embodiment will be described below.

[0261] Referring to FIG. 14, in this embodiment, the filter (325a) may be located on the outside of the refrigerator door (21). For example, the filter (325a) may be located in the cabinet (10).

[0262] In this case as well, the arrangement of the remaining components other than the filter (325a) may be the same as in the first embodiment or the second embodiment.

[0263] FIG. 15 is a perspective view of a refrigerator door according to a fourth embodiment of the present invention, and FIG. 16 is a drawing showing the second door in an open state in the refrigerator door according to a fourth embodiment of the present invention. FIG. 17 is a cross-sectional view taken along 17-17 of FIG. 15.

[0264] This embodiment is identical to previous embodiments in other respects, except that the storage space is reduced and the arrangement of the container and surrounding structures differs. Therefore, only the characteristic parts of this embodiment will be described below.

[0265] Referring to FIGS. 15 to 17, 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. Accordingly, there is an advantage in that the overall thickness of the door (20) can be reduced.

[0266] When the second door (170) equipped with the container (200) is closed, at least a portion of the container (200) may overlap with the ice-making chamber (130) in the vertical direction (Z-axis direction).

[0267] When the second door (170) equipped with the container (200) is closed, at least a portion of the container (200) may overlap vertically with one or more of the ice bin (134) and the ice maker (132).

[0268] At least a portion of the opening (252) of the above container (200) may overlap with the above ice-making chamber (130) in the vertical direction.

[0269] In this embodiment, the filter (325) may be placed in the refrigerator door (21), or it may be placed in the cabinet (10) as in the third embodiment.

[0270] FIG. 18 is a drawing showing a refrigerator door according to the fifth embodiment of the present invention.

[0271] This embodiment is identical to previous embodiments in other respects, except that the second door includes a panel assembly through which light can pass. Accordingly, the characteristic parts of this embodiment will be described below.

[0272] Referring to FIG. 18, in 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).

[0273] 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.

[0274] 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.

[0275] 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.

[0276] 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.

[0277] FIG. 19 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.

[0278] 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.

[0279] Referring to FIG. 19, 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).

[0280] 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).

[0281] FIGS. 20 and 21 are drawings illustrating various communication relationships between the space of the ice-making room and the dispenser housing.

[0282] First, referring to FIG. 20 (a), cold air is supplied to the ice-making room (130) by the first duct (510), and the cold air from the ice-making room (130) can be discharged through the second duct (520).

[0283] The space (113) of the dispenser housing (112) located below the ice-making room (130) may not be connected to the ice-making room (130).

[0284] As another example, referring to FIG. 20(b), the ice-making chamber (130) and the space (113) may be connected by a connecting duct (540). Thus, some of the cold air supplied to the ice-making chamber (130) may flow into the space (113). When the container (200) is placed in the space (113), the water and / or ice supplied to the container (200) may be maintained at a low temperature.

[0285] As another example, referring to FIG. 21 (a), the ice-making room (130) and the space (113) may be connected by a connecting duct (540). A fan (541) may be provided in the connecting duct (540). A temperature sensor may be provided in the connecting duct (540) or the space (112). The space (113) may be connected to the second duct (520) by an exhaust duct (546).

[0286] When the temperature detected by the temperature sensor is above a reference temperature, the fan (541) may operate. The fan (541) may operate for a set time, or the fan (541) may stop when the temperature detected by the temperature sensor reaches a set temperature lower than the reference temperature. Alternatively, the temperature sensor may be omitted, and the fan (541) may be turned on and then turned off after a certain period. Of course, it is also possible for the fan (541) to operate only when the container (200) is detected.

[0287] Accordingly, when the fan (541) is stopped, the flow of cold air from the ice-making room (130) into the space (113) may be restricted, and when the fan (541) is operated, some of the cold air supplied to the ice-making room (130) may flow into the space (113). When the container (200) is located in the space (113), the water and / or ice supplied to the container (200) may be maintained at a low temperature. The cold air supplied to the space (113) may flow into the second duct (520) through the discharge duct (546).

[0288] As another example, referring to FIG. 21 (b), the ice-making room (130) and the space (113) may be connected by a connecting duct (540). The connecting duct (540) may be equipped with a damper (542). A temperature sensor may be equipped in the connecting duct (540) or the space (112). The space (112) may be connected to the second duct (520) by an exhaust duct (546).

[0289] When the temperature detected by the temperature sensor is above a reference temperature, the damper (542) can open the connecting duct (540). The damper (542) can close the connecting duct (540) after a set time has elapsed or when the temperature detected by the temperature sensor reaches a set temperature lower than the reference temperature. Alternatively, the temperature sensor may be omitted, and the damper (542) may close the connecting duct (540) after opening it at regular intervals. Of course, it is also possible for the damper (542) to operate only when the container (200) is detected.

[0290] Accordingly, when the damper (542) is not operated, the flow of cold air from the ice-making room (130) into the space (113) may be restricted, and when the damper (542) is operated and the connecting duct (540) is opened, some of the cold air supplied to the ice-making room (130) may flow into the space (113). When the container (200) is located in the space (113), the water and / or ice supplied to the container (200) may be maintained at a low temperature. The cold air supplied to the space (113) may flow into the second duct (520) through the discharge duct (546).

[0291] FIG. 22 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.

[0292] 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.

[0293] Referring to FIG. 22, 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.

[0294] In this case as well, when the second door (170) is opened, the user can easily grab the handle (230A).

[0295] In the case of this embodiment, when the second door (170) is closed, the handle (230A) may not face the lever (111) described above.

[0296] In this case, the front-rear width of the container (200) (as the arrangement direction of the first door and the second door, refer to the width in the Y-axis direction in FIG. 11) can be reduced without reducing the volume of the container (200). When the front-rear width of the container (200) is reduced, the depth of the dispenser housing (112) can be reduced, and it may be possible to reduce the thickness of the first door (100).

[0297] In addition to the above embodiments, the present specification may further include the following embodiments.

[0298] 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).

[0299] 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).

[0300] The ice stored in the main ice bin can be supplied to the sub ice bin automatically or manually.

[0301] 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.

[0302] 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.

[0303] 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.

[0304] 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.

[0305] 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.

[0306] 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.

[0307] 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.

[0308] 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.

[0309] 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.

[0310] 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.
