Description

Ice makers and refrigerators

[0001] This specification relates to an ice maker and a refrigerator.

[0002] In general, a refrigerator is a home appliance that allows food to be stored at low temperatures in an internal storage space that is shielded by a refrigerator door. It is configured to store stored food in an optimal condition by cooling the interior of the storage space using cold air generated through heat exchange with a refrigerant circulating in a refrigeration cycle.

[0003] The above refrigerator can be placed independently in a kitchen or living room, or stored inside a kitchen cabinet.

[0004] The above refrigerators are gradually becoming larger and more multifunctional in line with the trend of changing eating habits and higher-end products, and refrigerators equipped with various structures and convenient devices that take user convenience into consideration are being released.

[0079] In the present specification, an ice-making device may include a tray that forms an ice-making cell, which is a space where water changes into ice. The ice-making device may further include a cooling unit for supplying cold to the ice-making cell. The ice-making device may further include a water supply unit for supplying water to the ice-making cell. The ice-making device may further include a controller.

[0080] The above cooling unit, as a source that supplies cold, can be referred to as a cold source.

[0081] The above ice making device may further include an ice unit.

[0082] The above tray may include a first tray. The above tray may further include a second tray.

[0083] The first tray and the second tray can produce different types of ice.

[0084] The water supply unit can independently supply water to each of the first tray and the second tray. The water supply unit can be configured to supply water to the first tray and the second tray simultaneously.

[0085] The above water supply unit may include a pump for pumping water.

[0086] The above cooling unit may be defined as a means for cooling the ice making cell, including an evaporator (or cooler) and at least one thermoelectric element.

[0091] The above-mentioned ice separating unit can separate ice independently from each of the first tray and the second tray or simultaneously separate ice from the first tray and the second tray.

[0092] For example, power from the drive unit may be simultaneously transferred to the first tray and the second tray, heat from a heater or refrigerant pipe may be simultaneously transferred to the first tray and the second tray, or water may be simultaneously transferred to the first tray and the second tray.

[0093] FIG. 1 is a perspective view of an ice maker according to an embodiment of the present invention, and FIG. 2 is a front view showing an open state of a door of an ice maker according to an embodiment of the present invention. FIG. 3 is a cutaway view showing the interior of an ice maker according to an embodiment of the present invention. FIG. 4 is a drawing showing the interior of an ice maker according to an embodiment of the present invention. FIG. 5 is a refrigerant cycle diagram constituting a cooling unit according to an embodiment of the present invention.

[0094] Referring to FIGS. 1 to 5, the ice making device (1) of the present embodiment can be installed independently to produce ice.

[0095] The above ice making device (1) may include a cabinet (10) forming an outer shape. The above ice making device (1) may further include a door (20) connected to the cabinet (10).

[0096] The cabinet (10) may include an ice-making chamber (12) for forming ice. The cabinet (10) may further include a storage chamber (13) for storing ice.

[0097] The ice making room (12) and the storage room (13) may be partitioned by a partition member. The ice making room (12) and the storage room (13) may be communicated by a communication hole of the partition member. Alternatively, the ice making room (12) and the storage room (13) may be communicated without a partition member.

[0098] Alternatively, it is also possible for the ice making room (12) to include the storage room (13), or for the storage room (13) to include the ice making room (12).

[0099] The cabinet (10) may include a front opening (102). The door (20) may open and close the front opening (102). The door (20) may open and close the front opening (102) by, for example, a rotational motion.

[0100] When the door (20) opens the front opening (102), the user can access the storage compartment (13) through the front opening (102). The user can take out ice stored in the storage compartment (13) through the front opening (102).

[0101] The above ice making device (1) may further include an ice making unit (40) located in the ice making room (12).

[0102] Ice generated in the ice making unit (40) can fall from the ice making unit (40) and be stored in the storage room (13).

[0103] The cabinet (10) may include an inner case (101) forming the ice making room (12). The cabinet (10) may further include an outer case (110) arranged on the outside of the inner case (101).

[0104] Although not shown, insulation may be provided between the inner case (101) and the outer case (100).

[0105] The above inner case (101) can additionally form the storage room (13).

[0106] The above ice making room (12) can be formed on one side inside the inner case (101).

[0107] The ice making unit (40) may be positioned close to the rear wall (101a) of the inner case (101). If the ice making unit (40) is positioned close to the rear wall (101a) of the inner case (101), the usability of the storage room (13) may be increased.

[0108] To make it easy for the user to access the storage room (13), the ice produced in the ice making unit (40) can fall in a direction closer to the door (20).

[0109] The above cabinet (10) may further include a machine room (18) partitioned from the storage room (13). The machine room (18) may be located, for example, on one side of the storage room (13).

[0110] Although not limited, a portion of the storage room (13) may be located between the ice making room (12) and the machine room (18). The volume of the storage room (13) may be larger than the volume of the ice making room (12) and the volume of the machine room (18).

[0111] The above machine room (18) can be placed on the outside of the inner case (101).

[0112] The inner case (101) may include a bottom wall (104) forming the bottom of the storage room (13). The machine room (18) may be located on one side of the bottom wall (104).

[0113] The above floor wall (104) may be provided with a drainage hole (105) for discharging water.

[0114] A portion of a cooling unit may be located in the above machine room (18). The cooling unit may be, for example, a refrigerant cycle for circulating refrigerant.

[0115] The above cooling unit may include a compressor (183), a condenser (184), an expander (186), and a cooler (50). The cooler (50) may be an evaporator through which refrigerant flows.

[0116] In the present embodiment, the refrigerant cycle may control the flow of refrigerant by a valve (188). The refrigerant cycle may include a bypass pipe (187) for bypassing the refrigerant discharged from the compressor (183) to the inlet side of the cooler (50). The valve (188) may be provided in the bypass pipe (187).

[0117] When the valve (188) is turned off, the refrigerant compressed in the compressor (183) can flow directly to the condenser (184). When the valve (188) is turned on, some or all of the refrigerant compressed in the compressor (183) can be bypassed to the bypass pipe (187) and flow directly to the cooler (50). Although not limited, the refrigerant of the compressor (183) can flow to the evaporator during the separating process.

[0118] The refrigerant flowing through the above cooler (50) can flow to the compressor (183) after flowing through the accumulator (189).

[0119] The compressor (183) and the condenser (184) may be located in the machine room (18). The machine room (18) may be provided with a condenser fan (185) to allow air to pass through the condenser (184). The condenser fan (185) may be, for example, placed between the condenser (184) and the compressor (183).

[0120] The front of the cabinet (10) may be provided with a front grill (180) in which air holes (182) are formed. A plurality of air holes (182) may be formed in the front grill (180). The front grill (180) may be positioned on one side of the front opening (102). When the door (20) closes the front opening (102), the door (20) may cover a portion of the front grill (180).

[0121] The above cooler (50) may include a refrigerant pipe (510, 520) through which refrigerant flows. At least a portion of the cooler (50) may be located in the ice making room (12).

[0122] At least a portion of the cooler (50) may be in contact with the ice making unit (40). That is, water supplied to the ice making unit (40) may be phase-changed into ice by the low-temperature refrigerant flowing through the cooler (50). Alternatively, the cooler (50) may be positioned adjacent to the ice making unit (40).

[0123] The method in which the above cooler (50) directly contacts the above ice-making unit (40) to create ice can be called a direct cooling method.

[0124] As another example, the air that has exchanged heat with the cooler (50) may be supplied to the ice making unit (40), so that the water in the ice making unit (40) may be phase-changed into ice by the cooling air. The method of producing ice by supplying cooling air may be called an indirect cooling method or an air cooling method. In the case of the indirect cooling method, the cooler (50) may not be located in the ice making room (12). However, additionally, a guide duct may be provided to guide the cooling air that has exchanged heat with the cooler (50) to the ice making room (12).

[0125] In this embodiment, the ice making unit (40) can produce a single type of ice or at least two different types of ice.

[0126] Hereinafter, an example will be described in which the ice making unit (40) produces at least two different types of ice.

[0127] The ice making unit (40) may include a first tray unit (410) for forming a first type of first ice (I1). The ice making unit (40) may further include a second tray unit (450) for forming a second type of second ice (I2) different from the first type.

[0128] Of course, the above ice making unit (40) may also include only one of the first tray unit (410) and the second tray unit (450) described later.

[0129] The first ice (I1) and the second ice (I2) may differ in at least one of shape, size, transparency, etc.

[0130] Hereinafter, it will be explained by way of example that the first ice (I1) is polygonal ice and the second ice (I2) is spherical ice.

[0131] The storage room may include a first storage space (132). The storage room may further include a second storage space (134).

[0132] Ice produced in the first tray unit (410) can be stored in the first storage space (132). Ice produced in the second tray unit (450) can be stored in the second storage space (134).

[0133] Although not limited, the second storage space (134) may be defined by the ice bin (14). That is, the internal space of the ice bin (14) may serve as the second storage space (134). The ice bin (14) may be fixedly or detachably coupled to the inner case (101).

[0134] The above ice bin (14) can also be referred to as a partition member that partitions the storage room (13) into the first storage space (132) and the second storage space (134).

[0135] The volume of the first storage space (132) may be larger than the volume of the second storage space (134). Although not limited, the size of the first ice (I1) stored in the first storage space (132) may be smaller than the size of the second ice (I2) stored in the second storage space (134).

[0136] The front of the ice bin (14) may be positioned spaced apart from the rear of the front opening (102). The bottom surface of the ice bin (14) may be spaced apart from the bottom wall (104) of the storage room (13).

[0137] Accordingly, the first ice (I1) may be positioned on one side of the ice bin (14). The first ice (I1) may also be positioned on the other side of the ice bin (14). The first ice (I1) stored in the first storage space (132) may surround the ice bin (14).

[0138] The bottom wall (104) of the above storage room (13) can form the bottom of the second storage space (134).

[0139] The bottom wall (104) of the storage room (13) may be positioned lower than one end (102a) of the front opening (102). The bottom surface of the ice bin (14) may be positioned higher than one end (102a) of the front opening (102).

[0140] The ice bin (14) may be positioned adjacent to one side (the left side in the drawing) among the left and right sides of the inner case (101). The second tray unit (450) may be positioned adjacent to the one side. Accordingly, ice separated from the second tray unit (450) may be stored in the second storage space (134) of the ice bin (14). Ice separated from the first tray unit (410) may be stored in the first storage space (132) outside the second storage space (134).

[0141] When the amount of first ice stored in the first storage space (132) increases, the cabinet (10) may further include an opening cover (16) to prevent the first ice from being unintentionally discharged through the front opening (102) when the door (20) is opened. The opening cover (16) may be rotatably arranged on the inner case (101). The opening cover (16) may cover one side of the front opening (102).

[0142] The above opening cover (16) can be accommodated inside the storage compartment (13) while the door (20) is closed. When the door (20) is opened, one end of the opening cover (16) can be rotated so that the other end protrudes outward from the storage compartment (13).

[0143] The above opening cover (16) may be elastically supported, for example, by an elastic member (not shown). When the door (20) is opened, the opening cover (16) may be rotated by the elastic member.

[0144] The above opening cover (16) may be formed in a convex shape toward the door (20). Accordingly, although not limited, the first ice may be filled in the first storage space (132) up to one end (16a) of the opening cover (16).

[0145] When the opening cover (16) is rotated, a portion of the first ice is pulled outward from the storage chamber (13) while being positioned within the convex portion of the opening cover (16), so there is an advantage in that the user can easily obtain the first ice.

[0146] Of course, it is also possible to omit the opening cover (16) by varying the height of the other end (102a) of the front opening (102).

[0147] The above cabinet (10) may further include a guide (70) that guides ice separated from the ice making unit (40) to the storage room (13).

[0148] The above guide (70) may be arranged spaced apart from one side of the ice making unit (40). The guide (70) may guide the first ice (I1) separated from the first tray unit (410). The guide (70) may guide the second ice (I2) separated from the second tray unit (450).

[0149] For example, the guide (70) may include a first guide (710). The guide (70) may further include a second guide (730).

[0150] The first ice (I1) separated from the first tray unit (410) can fall to the first guide (710). The first ice (I1) can be moved to the first storage space (132) by the first guide (710).

[0151] The second ice (I2) separated from the second tray unit (450) can fall to the second guide (730). The second ice (I2) can be moved to the second storage space (134) by the second guide (730).

[0152] One end of the ice bin (14) can be positioned adjacent to one end of the second guide (730) so that the second ice (I2) can be moved to the second storage space (134).

[0153] To prevent the first ice and the second ice that fall through the guide (70) from being mixed, the ice making device (1) may further include a partition plate (80). The partition plate (80) extends in the vertical direction and may be coupled to the guide (70) or the ice making unit (40).

The water supply unit (330) may store water supplied from the water supply device (320) and supply it to the ice making unit (40).

[0162] In this embodiment, the water supply device (320) may be referred to as a first water supply unit. The water supply unit (730) may be referred to as a second water supply unit.

[0163] The above water supply device (320) may be located on one side of the ice making unit (40). Water supplied from the water supply device (320) may fall onto the ice making unit (40).

[0167] The water supply unit (330) may include a water storage unit (350) in which water is stored. The ice making unit (40) may include one or more through holes (426) through which water passes. Water supplied from the water supply device (320) and dropped toward the ice making unit (40) may be stored in the water storage unit (350) after passing through the through holes (426). The guide (70) may be provided with a plurality of through holes through which water passing through the ice making unit (40) passes.

[0168] When the water supply valve (304) is turned on, water supplied from the water supply device (320) can fall to the ice making unit (40) and then pass through the ice making unit (40) to be stored in the water storage unit (350).

[0169] The water storage unit (350) may be equipped with a water level detection unit (356) that detects the water level. When the water level of the water storage unit (350) detected by the water level detection unit (356) reaches a reference water level, the water supply valve (304) may be turned off.

[0170] In this specification, the process from when the water supply valve (304) is turned on until the water supply valve (304) is turned off may be referred to as a water supply process.

[0182] The above water supply unit (330) may further include a second connecting pipe (370, 372) connecting each pump (360, 362) and each water supply unit (380, 382).

[0183] The water supplied from the first water supply unit (380) to the first tray unit (410) can be used to create ice. The water that falls again from the first tray unit (410) can be stored in the water storage unit (350) after passing through the guide (70).

[0184] The water supplied from the second water supply unit (382) to the second tray unit (450) can be used to create ice. The water that falls again from the second tray unit (450) can be stored in the water storage unit (350) after passing through the guide (70).

The machine room (18) may be provided with a drain tube (362) connected to the drain pipe (360). The drain tube (362) may ultimately discharge water to the outside of the ice making device (1).

[0186] Below, the ice making unit (40) will be described in detail.

[0187] FIG. 9 is a perspective view showing the arrangement of a first tray unit and a second tray unit according to a first embodiment of the present invention, and FIGS. 10 and 11 are perspective views showing an ice making unit and a cooler according to the first embodiment of the present invention.

[0188] FIG. 12 is a bottom view of an ice making unit according to a first embodiment of the present invention, and FIG. 13 is a cross-sectional view taken along line 13-13 of FIG. 12.

[0189] Referring to FIGS. 9 to 13, the cooler (50) may be in contact with the ice making unit (40). The cooler (50) may be located, for example, on one side of the ice making unit (40).

[0190] The above ice making unit (40) may include a first tray unit (410) and a second tray unit (450) as described above.

[0191] The first tray unit (410) and the second tray unit (450) can be arranged in a horizontal direction. It is also possible for the first tray unit (410) and the second tray unit (450) to be arranged in a vertical direction.

[0192] The first tray unit (410) and the second tray unit (450) can be installed in the cabinet (10) while being connected to each other. That is, the first tray unit (410) and the second tray unit (450) can be modularized.

[0193] As another example, the first tray unit (410) and the second tray unit (450) may be installed in the cabinet (10) in a separated state. The first tray unit (410) and the second tray unit (450) may be positioned close to each other in the horizontal direction.

[0194] The above first tray unit (410) may include a first ice-making cell (440).

[0195] In this embodiment, the ice-making cell refers to a space where ice is created. One ice can be created in one ice-making cell.

[0196] The first tray unit (410) may include a first tray. The first tray may include a first tray body (420). The first tray may further include a second tray body (430) coupled to the first tray body (420).

[0197] The above first tray may form, for example, a plurality of first ice-making cells (440). A plurality of second tray bodies (430) may be coupled to the first tray body (420).

[0198] The first ice-making cell (440) may be defined by one cell or may be defined by a plurality of cells. For example, the first ice-making cell (440) may include a first one-side cell (442) and a first other-side cell (441). Although not limited, the first one-side cell may be either the first lower cell or the first upper cell. The first other-side cell may be another one of the first lower cell and the first upper cell. The first one-side cell may be either the first left cell or the first right cell. The first other-side cell may be another one of the first left cell or the first right cell. Although not limited, it is also possible that the terms of the first one-side cell and the first other-side cell are opposite.

[0199] The first other side cell (441) can be formed by the first tray body (420). The first one side cell (442) can be formed by the second tray body (430).

[0200] For example, the first tray body (420) may form a plurality of first side cells (441). Each of the plurality of second tray bodies (430) may form a first side cell (442).

[0201] Therefore, when the plurality of second tray bodies (430) are combined into a single first tray body (420), a plurality of first ice-making cells (440) can be formed.

[0202] The first tray body (420) may include a first opening (423). The first opening (423) is in communication with the first other side cell (441).

[0203] The number of the first openings (423) may be the same as the number of the first ice-making cells (440).

[0204] The first one-side cell (442) can form one side of the first ice, and the first other-side cell (441) can form the other side of the first ice.

[0205] After the second tray body (430) is coupled to the first tray body (420), the separation of the second tray body (430) from the first tray body (420) may be restricted.

[0206] Water supplied from the first water supply unit (380) can pass through the first opening (423) and be supplied to the first ice-making cell (440). Therefore, the first opening (423) can serve as a water supply opening during the ice-making process.

[0207] A portion of the water supplied to the first ice-making cell (440) may fall to the lower portion of the first tray unit (410) through the first opening (423). Therefore, the first opening (423) may serve as a water discharge opening during the ice-making process.

[0208] The ice generated in the first ice-making cell (440) can be separated from the first tray unit (410) through the first opening (423) during the ice-breaking process. Therefore, the first opening (423) can serve as an ice discharge opening during the ice-breaking process.

[0209] Each of the first one-sided cell (442) and the first other-sided cell (441) may be formed in a hexahedral shape, for example. The volume of the first other-sided cell (441) and the volume of the first one-sided cell (442) may be the same or different.

[0210] After the first ice is created in the first ice-making cell (440), the horizontal circumference (or horizontal cross-sectional area) of the first other-side cell (441) may be larger than the horizontal circumference (or horizontal cross-sectional area) of the first one-side cell (442) so that the ice can be discharged through the first opening (423).

[0211] That is, during the water supply process, ice-making process, or ice-breaking process, the second tray body (430) and the first tray body (420) are maintained in a combined state so that the shape of the first ice-making cell (440) can be maintained.

[0212] The cooler (50) can be brought into contact with the second tray body (430) so that ice is first generated in the first side cell (442).

[0213] The above first tray body (420) may include a passage hole (421, 425) for water to pass through.

[0214] The second tray unit (450) may include a second tray forming a second ice-making cell (451).

[0215] The second tray may be defined by one tray or by multiple trays. For example, the second tray may include a first tray (460) and a second tray (470). Although not limited, the first tray may be an upper tray, a left tray, or a first tray section. The second tray (470) may be a lower tray, a right tray, or a second tray section. It is also possible that the terms for the first tray (460) and the second tray (470) are opposite to each other.

[0216] The second ice-making cell (451) may be defined by one cell or by multiple cells. For example, the second ice-making cell (451) may include a second one-side cell (462) and a second other-side cell (472).

[0217] The above-mentioned one-sided tray (460) can form the second one-sided cell (462). The above-mentioned other-sided tray (470) can form the second other-sided cell (472). Each of the second one-sided cell (462) and the second other-sided cell (472) can be formed in a hemispherical shape, for example.

[0218] For example, the second tray can form a plurality of second ice-making cells (451). Accordingly, the one-side tray (460) can form a plurality of second one-side cells (462). The other-side tray (470) can form a plurality of second other-side cells (472).

[0219] A portion of the first ice-making cell (440) may be positioned at the same height as the second ice-making cell (451). For example, at least a portion of the first ice-making cell (440) may be arranged to overlap the second ice-making cell (451) in the horizontal direction.

[0220] The second ice-making cell (451) may be positioned between the rotation center (C1) of the other tray (470) and the first ice-making cell (440). The other tray (470) may be connected to the driving unit (690) by a shaft (489). The shaft (489) may provide the rotation center (C1) of the other tray (470).

[0221] The heights of one end of the first ice-making cell (440) and one end of the second ice-making cell (451) may be different. For example, one end of the first ice-making cell (440) may be positioned lower than one end of the second ice-making cell (451).

[0222] The heights of the other end of the first ice-making cell (440) and the other end of the second ice-making cell (451) may be different. For example, the other end of the first ice-making cell (440) may be positioned higher than the other end of the second ice-making cell (451).

[0223] The contact surface of the one-side tray (460) and the other-side tray (470) may have a different height from the joining portion of the first tray body (420) and the second tray body (430). For example, the contact surface of the one-side tray (460) and the other-side tray (470) may be positioned higher than the joining portion of the first tray body (420) and the second tray body (430).

[0224] The height of the first ice-making cell (440) and the height of the second ice-making cell (451) may be different. For example, the height of the first ice-making cell (440) may be smaller than the height of the second ice-making cell (451).

[0225] The maximum horizontal circumference of the first ice-making cell (440) may be different from the maximum horizontal circumference of the second ice-making cell (451). For example, the maximum horizontal circumference of the first ice-making cell (440) may be smaller than the maximum horizontal circumference of the second ice-making cell (451).

[0226] The number of the first ice-making cells (440) may be different from the number of the second ice-making cells (451). For example, the number of the first ice-making cells (440) may be greater than the number of the second ice-making cells (451).

[0227] The volume of the first ice-making cell (440) may be different from the volume of the second ice-making cell (451). The volume of the first ice-making cell (440) may be smaller than the volume of the second ice-making cell (451).

[0228] The sum of the volumes of the plurality of first ice-making chambers (440) may be different from the sum of the volumes of the plurality of second ice-making cells (451). For example, the sum of the volumes of the plurality of first ice-making chambers (440) may be greater than the sum of the volumes of the plurality of second ice-making cells (451).

[0229] The above-mentioned other side tray (470) may include a second opening (473).

[0230] The water supply process and the ice making process can be performed while the one-sided tray (460) and the other-sided tray (470) are in contact to form the second ice making cell (451).

[0231] Water supplied from the second water supply unit (382) can pass through the second opening (473) and be supplied to the second ice-making cell (451). Therefore, the second opening (473) can serve as a water supply opening during the ice-making process.

[0232] A portion of the water supplied to the second ice-making cell (451) may fall to the lower portion of the second tray unit (450) through the second opening (473). Therefore, the second opening (473) may serve as a water discharge opening during the ice-making process.

[0233] During the moving process, the other side tray (470) can be moved relative to the one side tray (460).

[0234] The first opening (423) and the second opening (473) may be positioned at different heights. For example, the first opening (423) may be positioned higher than the second opening (473).

[0235] The second tray unit (450) may further include a bracket (452) that supports the one-sided tray (460). The bracket (452) may be fixed in position within the ice making room (12).

[0236] The above bracket (452) can be supported on a wall forming the ice making room (12). For example, the above bracket (452) can be supported on the inner case (101).

[0237] The above bracket (452) can provide a space for accommodating at least a portion of the one-side tray (460) and the other-side tray (470).

[0238] A portion of the above one-sided tray (460) may penetrate the bracket (452) and another portion may be seated on the bracket (452).

[0239] A driving unit (690) for moving the other side tray (470) may be installed on the above bracket (452).

[0240] The bracket (452) may include a peripheral portion (635). The peripheral portion (635) may be provided with a mounting portion (636). The mounting portion (636) may be mounted on the first tray unit (410). For example, the mounting portion (636) may be mounted on the first tray body (420). When the mounting portion (636) is mounted on the first tray body (420), a portion of the first tray unit (410) may be positioned at the same height as a portion of the second tray unit (450).

[0241] The above bracket (452) may include a passage hole (634) for water to pass through.

[0242] The second tray unit (450) may further include a supporter (480) that supports the other tray (470).

[0243] With the other side tray (470) secured to the supporter (480), the supporter (480) and the other side tray (470) can be moved together. For example, the supporter (480) can be movably connected to the one side tray (460).

[0244] The above supporter (480) may include a supporter opening (482a) for water to pass through. The supporter opening (482a) may be aligned with the second opening (473).

[0245] The diameter of the above supporter opening (482a) may be larger than the diameter of the second opening (473).

[0246] The above first ice can be discharged from the first ice-making cell through the first opening (423). On the other hand, the above second ice cannot be discharged from the second ice-making cell through the second opening (473).

[0247] In the present embodiment, in the case of the first tray, since the first ice can be discharged from the first ice-making cell through the first opening (423) during the freezing process, the first tray can be called an open type tray.

[0248] For open type trays, the diameter or size of the opening may be equal to or larger than the diameter or size of the first ice making cell.

[0249] On the other hand, in the case of the second tray, since the second ice cannot be discharged to the outside from the second ice-making cell through the second opening (473), the second tray can be called a closed type tray.

[0250] In the case of a closed type tray, for ice separation, at least one of the one-side tray (460) and the other-side tray (470) may be configured to move or the one-side tray (460) and the other-side tray (470) may be configured to separate from each other. In the present embodiment, the movement of the other-side tray (470) is described as an example.

[0251] The second tray unit (450) may further include a pusher (490) for separating ice from the other tray (470) during the separating process. The pusher (490) may be installed, for example, on the bracket (452). The pusher (490) may pressurize the other tray (470) or pressurize the second ice during the separating process.

[0252] The above pusher (490) may include a pushing bar (492). When the other side tray (470) and the supporter (480) are moved during the ice-making process, the pushing bar (492) may penetrate the supporter opening (482a) of the supporter (480) to pressurize the other side tray (470) or the second ice.

[0253] When the other side tray (470) is pressed by the pushing bar (492), the shape of the other side tray (470) is deformed, and the second ice can be separated from the other side tray (470). To enable deformation of the other side tray (470), the other side tray (470) can be formed of a non-metallic material. In terms of ease of deformation, the other side tray (470) can be formed of a flexible material.

[0254] Meanwhile, the cooler (50) may include a first refrigerant pipe (510) that is in contact with the first tray unit (410) or positioned adjacent to the first tray unit (410).

[0255] The above cooler (50) may further include a second refrigerant pipe (520) positioned adjacent to or in contact with the second tray unit (450).

[0256] The above first refrigerant pipe (510) and the above second refrigerant pipe (520) can be connected in series or in parallel.

[0257] The first refrigerant pipe (510) may include the first inlet pipe (511). The first inlet pipe (511) may be located at one side of the first tray body (420). The first inlet pipe (511) may extend from a position adjacent to the driving unit (690). The first inlet pipe (511) may extend from one side of the driving unit (690). That is, the first inlet pipe (511) may extend in a space between the driving unit (690) and the rear wall (101a) of the inner case (101).

[0258] The above first refrigerant pipe (510) may further include a first bent pipe (512) extending from the first inlet pipe (511).

[0259] The above first refrigerant pipe (510) may further include a first cooling pipe (513) extending from the first bent pipe (512).

[0260] The first cooling tube (513) can be in contact with one surface of the second tray body (430). Therefore, the second tray body (430) can be cooled by the refrigerant flowing through the first cooling tube (513).

[0261] The first cooling tube (513) may include a plurality of straight sections (513a). The first cooling tube (513) may further include a curved connecting section (513b) connecting the ends of two adjacent straight sections (513a).

[0262] The first inlet pipe (511) may be positioned adjacent to a boundary portion between the first tray unit (410) and the second tray unit (450). The first cooling pipe (513) may extend from the boundary portion in a direction away from the second tray unit (450).

[0263] One straight section can contact one surface of a plurality of second tray bodies (430).

[0264] The above plurality of straight sections (513a) can be arranged at substantially the same height.

[0265] The first refrigerant pipe (510) may further include a first connecting pipe (514) extending from an end of the first cooling pipe (513). The first connecting pipe (514) may be extended to have a lower height than the first cooling pipe (513).

[0266] The first refrigerant pipe (510) may further include a second cooling pipe (515) connected to the first connecting pipe (514). The second cooling pipe (515) may be positioned lower than the first cooling pipe (513).

[0267] The above second cooling tube (515) can contact the side of the second tray body (430).

[0268] The second cooling tube (515) may include a plurality of straight sections (515a, 515b). The second cooling tube (515) may further include a curved connecting section (515c) connecting two adjacent straight sections (515a, 515b).

[0269] The above plurality of second tray bodies (430) can be arranged in a plurality of columns and rows.

[0270] Some of the straight portions (515a, 515b) among the plurality of straight portions (515a, 515b) may be in contact with one side of the second tray body (430) of one row. Other of the straight portions (515b) among the plurality of straight portions (515a, 515b) may be in contact with the second tray bodies (430) of two adjacent rows, respectively.

[0271] For example, some of the straight portions (515a) may contact, for example, the first side of the second tray body in the first row.

[0339] The shaft hole (465a) of the above pair of hinge parts (465) can be connected to the shaft p (489).

[0340] When the first tray body (461) penetrates the through hole (601), the pair of hinge parts (465) can also penetrate the through hole (601).

[0341] The above one-sided tray (460) may include a discharge path (466) for discharging water that has fallen on one side of the one-sided tray (460).

[0342] One side of the extension (463) may be sunken, and the discharge path (466) may be formed by a flow path wall protruding from the other side of the extension (463). The discharge path (466) may extend, for example, in the fourth direction. The discharge path (466) may extend to the side end of the extension (463).

[0343] The above discharge path (466) may be arranged to communicate with any one of the plurality of settling grooves (468). That is, a portion of the second refrigerant pipe (520) may be arranged to overlap the discharge path (466) in the first direction.

[0344] The above-described one-sided tray (460) may further include a fixing projection (464b) inserted into the fixing groove (606) of the first fixing portion (605). The fixing projection (464b) may, for example, extend from the extension portion (463). For example, a plurality of fixing projections (464b) may be arranged spaced apart from each other in the second direction.

[0345] Meanwhile, the partition plate (80) may be installed, for example, on the bracket (452). The partition plate (80) may be provided with a coupling extension portion (82).

The hook (84) may extend in a direction intersecting the coupling extension portion (82).

[0346] The partition plate (80) may be positioned adjacent to the fifth wall (626) in the bracket (452). That is, the partition plate (80) may be positioned on the opposite side of the fourth wall (620). Accordingly, the partition plate (80) may restrict ice separated from the second ice-making cell (451) during the ice-making process from moving away from the fourth wall (620).

[0347] Although not limited, the plurality of coupling extensions (82) may be coupled to the second wall (611) and the third wall (612).

[0348] The second wall (611) and the third wall (612) can be positioned between the plurality of coupling extensions (82). In this state, the hook (84) of each coupling extension (82) can be coupled to the first coupling hole (611a) and the second coupling hole (612a).

[0349] Fig. 22 is a drawing showing a state in which a case is coupled to one side of a tray of the present embodiment, Fig. 23 is a drawing showing a state in which an insulating member is accommodated in the case of the present embodiment, and Fig. 24 is a drawing showing a state in which a tray on the other side is positioned on one side of the case of the present embodiment.

[0350] Referring to FIG. 12, FIG. 22 to FIG. 24, the second tray unit (450) may further include an insulating member (660) surrounding the one-sided tray (460).

[0351] The above insulating member (660) may, for example, surround the first tray body (461). Although not limited, the one-side tray (460) may be formed of a metal material, and the insulating member (660) may minimize the cold or heat supplied to the one-side cell (462) from being transferred to the outside.

[0352] Although not limited, the exterior of the insulating member (660) may be formed as a rectangular parallelepiped overall. The insulating member (660) may include a first opening (662) for the first tray body (461) to pass through. The vertical length of the insulating member (660) may be equal to or smaller than the vertical length of the first tray body (461).

[0353] When the first tray body (461) penetrates the first opening (662), one surface of the insulating member (660) can come into contact with the other surface of the extension portion (462).

[0354] The insulating member (660) may include a first recessed space (663) in which the second fixing member (607) is positioned. The first recessed space (663) may be recessed into one side of the insulating member (660). Alternatively, the first recessed space (663) may be recessed from the side of the insulating member (660) toward the first opening (662).

[0355] The second fixing part (607) and the one-side tray (460) can be fastened while the second fixing part (607) is positioned in the first sunken space (663).

[0356] The above insulating member (660) may further include a second recessed space (664) in which the discharge passage (466) is positioned. The second recessed space (664) may be recessed in one surface of the insulating member (660). Alternatively, the second recessed space (664) may be recessed in the second direction in the side surface of the insulating member (660).

[0357] The second tray unit (450) may further include a supporter (650) that supports the insulating member (660).

[0358] The above supporter (650) may include a supporter plate (651) having a second opening (652) for the first tray body (461) to pass through. The insulating member (660) may be mounted on the supporter plate (651).

[0359] The supporter plate (651) may include a receiving hole (657) for receiving a fastening member (S1) for coupling the other side tray (470) and the supporter (480). Accordingly, when the one side tray (460) and the other side tray (470) are in contact for ice making, interference between the fastening member (S1) and the supporter (650) can be prevented.

[0360] The supporter (650) may further include a peripheral wall (650) extending from the supporter plate (660). For example, the peripheral wall (650) may extend from the edge of the supporter plate (660).

[0361] The above-mentioned peripheral wall (650) can surround the side surface of the insulating member (660). The above-mentioned peripheral wall (650) and the supporter plate (660) can form a space in which the insulating member (660) is accommodated. The insulating member (660) can be fitted into the space formed by the supporter (650). Since the insulating member (660) is formed of a material that can change shape, the insulating member (600) can be fitted into the space formed by the supporter (650). When the insulating member (600) is fitted into the supporter (650), the insulating member (600) can be maintained in a state of being coupled to the supporter (650) without a separate coupling means.

[0362] Accordingly, the peripheral wall (650) can come into contact with the side surface of the insulating member (660).

[0363] The above peripheral wall (650) may include a first slot (654) aligned with the first recessed space (663). The second fixing member (407) may be positioned in the first slot (654).

[0364] The second fixing part (407) can be prevented from interfering with the peripheral wall (650) by the first slot (654).

[0365] The above-mentioned peripheral wall (650) may further include a second slot (655) in which the discharge path (466) is positioned. The second slot (655) may prevent the discharge path (466) from interfering with the peripheral wall (650).

[0366] The supporter (650) may further include an extension portion (666) extending in the second direction from the peripheral wall (650). The extension portion (666) may contact the other surface of the extension portion (463) of the one-sided tray (560).

[0367] In a state where the insulating member (660) surrounds the first tray body (461) and the supporter (650) supports the insulating member (666), a portion of the first tray body (461) may protrude from the other surface of the supporter plate (651). That is, the other surface (461a) of the first tray body (461) may be positioned lower than the other surface of the supporter plate (651). Accordingly, the other surface (461a) of the first tray body (461) may come into contact with the other tray (470).

[0368] Below, the series of processes by which ice is created in the ice making unit will be described.

[0369] The process for creating ice may include a water supply process. The process for creating ice may further include an ice-making process. The process for creating ice may further include an ice-breaking process.

[0370] When the above water supply process starts, the water supply valve (304) is turned on and water supplied from an external water source (302) flows along the water supply path. The water flowing along the water supply path is supplied to the ice making unit (40) through the water supply mechanism (320).

[0371] The water supplied to the ice making unit (40) falls to the lower side of the ice making unit (40) and is stored in the water storage unit (350). When the water level stored in the water storage unit (350) reaches the reference level, the water supply valve (304) is turned off, thereby ending the water supply process.

[0372] After the above water supply process is completed, the ice making process begins.

[0373] During the above ice-making process, the cooling unit may operate to allow low-temperature refrigerant to flow into the cooler (50). For example, the compressor (183) may be turned on. Of course, the condenser fan (185) may also be turned on. Alternatively, the compressor (183) and the condenser fan (185) may be turned on before the ice-making process and remain turned on during the ice-making process. The valve (188) may be turned off.

[0374] In the above ice-making process, water can be supplied to the ice-making unit (40) by the water supply unit (330).

[0375] The controller, which is not shown, can turn on the pumps (360, 362) simultaneously or sequentially.

[0376] For example, when the first pump (360) is operated, water can be supplied to the first tray unit (410) through the first water supply unit (380).

[0377] Water sprayed from the first water supply unit (380) can be supplied to the first ice-making cell (440) through the first opening (423) of the first tray body (420).

[0378] The water supplied to the first ice-making cell (440) flows toward one surface of the second tray body (430). Some of the water within the first ice-making cell (440) may be frozen by the first refrigerant pipe (510). The unfrozen water falls downward again through the first opening (423). The water falling downward through the first opening (423) is stored again in the water storage unit (350).

[0379] During the above ice-making process, ice is created on one side of the first ice-making cell (440) and grows toward the other side. As water is sprayed into the first ice-making cell (440), some of the water freezes. As the water is sprayed onto the ice created in the first tray body (420) or the second tray body (430), air bubbles in the water may be discharged from the water.

[0380] When the second pump (362) is operated, water can be supplied to the second tray unit (450) through the second water supply unit (382).

[0381] Water sprayed from the second water supply unit (382) can be supplied to the second ice-making cell (451) through the supporter opening (482a) of the supporter (480) and the second opening (473) of the other tray (470).

[0382] The water supplied to the second ice-making cell (451) flows toward the interior of the one-side tray (460). Some of the water within the second ice-making cell (451) may be frozen by the second refrigerant pipe (520). The unfrozen water falls downward again through the second opening (473). The water falling downward through the second opening (473) is stored again in the water storage unit (350).

[0383] During the above ice making process, the controller can determine whether ice making is completed in the tray unit.

[0384] The above ice making process can be determined to be completed when the temperature detected by the temperature sensor for detecting the temperature of each tray unit reaches the end reference temperature.

[0385] Once the ice-making process is complete, the ice-breaking process can be performed.

[0386] When the above-described ice-making process begins, the valve (188) may be turned on. When the valve (188) is turned on, the high-temperature refrigerant compressed in the compressor (183) may flow to the cooler (50). The high-temperature refrigerant flowing to the cooler (50) may exchange heat with the ice-making unit (40). When the high-temperature refrigerant flows to the cooler (50), heat may be transferred to the ice-making unit (40).

[0387] The first ice (I1) can be separated from the first tray unit (410) by the heat transferred to the ice making unit (40). When the first ice (I1) is separated from the first tray unit (410), the first ice (I1) can fall to the guide (70). The first ice (I1) that falls to the guide (70) can be stored in the first storage space (132).

[0388] The second ice (I2) can be separated from the surface of at least one tray (460) by the heat transferred to the ice making unit (40).

[0389] Over time, or when the temperature of each tray unit reaches a set temperature, the flow of high temperature refrigerant to the cooler (50) can be blocked.

[0390] Next, the driving unit (690) can be operated so that the second ice (I2) is separated from the second tray unit (450). By the operation of the driving unit (690), the other tray (470) can be moved in the positive direction (clockwise with reference to FIG. 13).

[0391] When the second ice (I2) is separated from the one-side tray (460) and the other-side tray (470) by the high-temperature refrigerant flowing to the cooler (50), the other-side tray (470) can be moved while the second ice (I2) is supported on the other-side tray (470). In this case, when the other-side tray (470) moves at an angle of approximately 90 degrees, the second ice (I2) can fall from the other-side tray (470).

[0392] On the other hand, if the second ice (I2) is separated from the one-side tray (460) by the high-temperature refrigerant flowing to the cooler (50) but is not yet separated from the other-side tray (470), the pusher (490) presses the other-side tray (470) while the other-side tray (470) moves by the ice-breaking angle, so that the second ice (I2) can be separated from the other-side tray (470) and fall.

[0393] When the second ice (I2) is separated from the second tray unit (450), the second ice (I2) can fall to the guide (70). The second ice (I2) that falls to the guide (70) can be stored in the second storage space (134).

[0394] After the other side tray (470) is moved in the forward direction by D, the other side tray (470) is moved in the reverse direction (counterclockwise in the drawing) by the driving unit (690) to come into contact with the one side tray (460).

[0395] When the ice-making process is performed once or a set number of times, the water in the water storage unit (350) can be discharged to the outside through the drain pipe (390) and the drain tube (392) (drain process). That is, the drain valve can be turned on for a certain period of time when the water drain condition is satisfied.

[0396] The next water supply process may begin after the drain process has been performed. When the drain process is performed intermittently, if the drain condition is not satisfied, the water supply process may be performed immediately after the ice removal process. If the drain condition is satisfied, the drain process may be performed after the ice removal process, and the water supply process may be performed after the drain process has been completed.

[0397] Meanwhile, it is also possible to apply the technology applied to the ice making device (1) to a refrigerator. That is, the refrigerator may include some or all of the components of the ice making device (1).

[0398] First, the ice-making unit (40) of the ice-making device (1) can be applied to the refrigerator. The refrigerator can include a cabinet having a storage compartment and a door for opening and closing the storage compartment. The ice-making compartment can be provided in the cabinet or the door.

[0399] The ice making unit (40) having the same structure or a similar form as the ice making unit (40) of the present embodiment may be provided in the ice making room.

[0400] In the present embodiment, the cooling unit in the ice making device (1) may be replaced with a cooling unit or refrigerant cycle that cools the storage compartment of the refrigerator.

[0401] The guide (70), water supply mechanism (320) and water supply unit (330) provided in the above ice making device (1) may be the same as or applied to the refrigerator, or may be applied with a shape, size or position modified to suit the characteristics of the refrigerator.
