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.

[0005] In Japanese Patent Publication No. 5687018, a prior art document, an automatic ice maker is disclosed.

[0006] The automatic ice maker may include an ice making room for forming ice, an evaporator disposed on the upper side of the ice making room, a water plate disposed on the lower side of the ice making room and rotatably supported by a support shaft, an ice making water tank assembled on the lower side of the water plate, a supply pump connected to the ice making water tank, a guide member positioned on one side of the ice making water tank and rotatable, and an ice storage room for storing ice.

[0007] During the ice-making process, water is supplied from a supply pump while the water dish closes the space of the ice-making room, and the water supplied to the ice-making cell can be cooled by an evaporator.

[0008] During the ice-making process, high-temperature gas is supplied to the evaporator, and the ice-making cell is heated, and at the same time, the water dish tilts downward, and during the process of the water dish tilting downward, the guide member rotates to cover the upper side of the water dish.

[0009] As the ice-making cell is heated, ice is separated from the ice-making cell, falls to the upper side of the guide member, and ultimately moves to the ice storage room.

[0010] However, in the case of the prior art, during the ice-making process, high-temperature gas is supplied to the evaporator to heat the ice-making cell, but a technology for separating ice from a water dish in case ice is not separated is not disclosed.

[0011] Additionally, in the case of the prior literature, it is not possible to create ice in a shape other than a cube shape, for example, a spherical shape.

[0012] Prior art document, Korean Patent Publication No. 10-2020-0057604, discloses an ice maker capable of producing spherical ice.

[0013] The ice maker comprises an upper assembly including one side tray defining an upper chamber which is part of an ice chamber; a lower assembly including another side tray defining a lower chamber which is part of the ice chamber; and a supporter supporting the other side tray and having a lower opening, the lower assembly being rotatable relative to the upper assembly; and a lower ejector having a lower pushing bar which penetrates the lower opening and presses the other side tray when the lower assembly is rotated to an open position for ejecting ice.

[0014] However, in the case of the above ice maker, since the lower ejector pressurizes the other tray during the ice-making process, a structure for supplying water to the supporter cannot be installed. Therefore, in the case of the above ice maker, the water supply unit must be installed in the upper assembly, and in order to produce transparent ice, a heater must be placed and operated during the ice-making process, which presents a drawback.

[0015] The present embodiment provides an ice making device and a refrigerator capable of producing ice with high transparency without the operation of a heater.

[0016] Optionally or additionally, the present embodiment provides an ice making device and refrigerator in which ice making efficiency is improved by supplying water to the ice making unit during the ice making process.

[0017] Optionally or additionally, the present embodiment provides an ice making device and a refrigerator that can improve ice separation performance and thus reduce ice-making time.

[0049] According to one embodiment, since water is supplied from the water supply unit to the ice-making cell during the ice-making process, there is an advantage in that ice with high transparency can be produced without the operation of the heater.

[0050] In one embodiment, water is supplied to the ice making unit during the ice breaking process, thereby improving the ice breaking efficiency and enhancing the ice separation performance.

[0114] Fig. 1 is a perspective view of an ice maker according to the present invention, and Fig. 2 is a front view showing the door of the ice maker according to the present invention in an open state. Fig. 3 is a cutaway view showing the interior of the ice maker according to the present embodiment. Fig. 4 is a drawing showing the interior of the ice maker according to the present embodiment. Fig. 5 is a refrigerant cycle diagram constituting a cooling unit.

[0115] Referring to FIGS. 1 to 5, the ice making device (1) of the present embodiment can be installed independently to produce ice.

[0116] 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).

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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.

[0121] 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).

[0122] The above ice making device (1) may further include an ice making unit (40) located in the ice making room (12).

[0123] Ice generated in the ice making unit (40) can fall from the ice making unit (40) and be stored in the storage room (13).

[0124] The cabinet (10) may further 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).

[0125] Although not shown, insulation may be provided between the inner case (101) and the outer case (100).

[0126] The above inner case (101) can additionally form the storage room (13).

[0127] The above ice making room (12) can be formed on one side inside the inner case (101).

[0128] 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.

[0129] 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).

[0130] 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).

[0131] 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).

[0132] The above machine room (18) can be placed on the outside of the inner case (101).

[0133] 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).

[0134] The above floor wall (104) may be provided with a drainage hole (105) for discharging water.

[0135] 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.

[0136] 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.

[0137] 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).

[0138] 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.

[0139] The refrigerant flowing through the above cooler (50) can flow to the compressor (183) after flowing through the accumulator (189).

[0140] 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).

[0141] 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).

[0142] 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).

[0143] 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).

[0144] 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.

[0145] 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).

[0146] In this embodiment, the ice making unit (40) can produce a single type of ice or at least two different types of ice.

[0147] Hereinafter, an example will be described in which the ice making unit (40) produces at least two different types of ice.

[0148] 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.

[0149] The first ice (I1) and the second ice (I2) may differ in at least one of shape, size, transparency, etc.

[0150] 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.

[0151] 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).

[0152] 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).

[0153] 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).

[0154] 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).

[0155] 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).

[0156] 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).

[0157] The bottom wall (104) of the above storage room (13) can form the bottom of the second storage space (134).

[0158] 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).

[0159] 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).

[0160] 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).

[0161] 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).

[0162] 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.

[0163] 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).

[0164] 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.

[0165] Of course, it is also possible to omit the opening cover (16) by varying the height of one end (102a) of the front opening (102).

[0166] 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).

[0167] The above guide (70) can be arranged spaced apart from the ice making unit (40). The guide (70) can guide the first ice (I1) separated from the first tray unit (410). The guide (70) can guide the second ice (I2) separated from the second tray unit (450).

[0168] For example, the guide (70) may include a first guide (710). The guide (70) may further include a second guide (730).

[0169] 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).

[0170] 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).

[0171] 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).

[0172] 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).

[0173] FIG. 6 is a drawing showing a water supply path in an ice making device according to a first embodiment of the present invention, and FIGS. 7 and 8 are drawings showing how water is supplied to an ice making unit according to the first embodiment.

[0174] Referring to FIGS. 6 to 8, the ice making device (1) may include a water supply path for guiding water supplied from a water source (302) to the ice making unit (40).

[0175] The above water supply path may include a first path (303) connected to the water supply source (302). A water supply valve (304) may be provided in the first path (303). By the operation of the water supply valve (304), the supply of water from the water supply source (302) to the ice maker (1) may be controlled. By the operation of the water supply valve (304), the supply flow rate when water is supplied to the ice maker (1) may be controlled.

[0176] The above water supply path may further include a second path (305) connected to the water supply valve (304). The second path (305) may be connected to a filter (306). The filter (306) may be located, for example, in the machine room (18).

[0177] The above water supply path may further include a third path (308) that guides water that has passed through the filter (306).

[0178] The above ice making device (1) may further include a water supply device (320). The water supply device (320) may be connected to the third flow path (308).

[0179] The above water supply device (320) can supply water to the ice making unit (40) during the water supply process.

[0180] The above ice making device (1) may further include a water supply unit (330). The water supply unit (330) may supply water to the ice making unit (40) during the ice making process. The water supply unit (330) may store water supplied from the water supply device (320) and supply it to the ice making unit (40).

[0181] 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.

[0182] 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).

[0183] The above water supply unit (330) may be located on the other side of the above ice making unit (40).

[0184] The water supply unit (330) may be separated from the water supply device (320). The water supply unit (330) may store water supplied from the water supply device (320) and supply it to the ice making unit (40).

[0185] In FIGS. 6 to 8, the dotted line shows the flow of water supplied from the water supply device (320), and the solid line shows the flow of water supplied from the water supply unit (330).

[0186] 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.

[0187] 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).

[0188] 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.

[0189] 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. For example, the water supply valve (304) may be turned off when the water level of the water storage unit (350) detected by the water level detection unit (356) reaches a reference water level.

[0190] The above water supply unit (330) may further include a water supply pump (360, 362) for pumping water stored in the water storage unit (350).

[0191] In the ice-making process of this embodiment, the water stored in the water storage unit (350) can be pumped by the water supply pump (360, 362) and supplied to the ice-making unit (40).

[0192] The above water supply pump (360, 362) may include a first pump (360). The above water supply pump (360, 362) may further include a second pump (362). When the first pump (360) operates, water may be supplied to the first tray unit (410). When the second pump (362) operates, water may be supplied to the second tray unit (450).

[0193] The first pump (360) and the second pump (362) can operate independently. The pumping capacities of the first pump (360) and the second pump (362) can be the same or different.

[0194] The above water supply unit (330) may further include a first connecting pipe (352, 354) connecting each of the above pumps (360, 362) and the water storage unit (350).

[0195] The above first connecting pipe (352, 354) can be connected to the water storage unit (350) at a height equal to or similar to the bottom of the water storage unit (350).

[0196] The above water supply unit (330) may further include a first water supply unit (380) for supplying water pumped by the first pump (360) to the first tray unit (410).

[0197] The above water supply unit (330) may further include a second water supply unit (382) for supplying water pumped by the second pump (362) to the second tray unit (450).

[0198] The above first water supply unit (380) can supply water to the first tray unit (410) from one side of the first tray unit (410).

[0199] The second water supply unit (382) can supply water to the second tray unit (450) from one side of the second tray unit (450).

[0200] The first water supply unit (380) and the second water supply unit (382) may be located on one side of the guide (70).

[0201] 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).

[0202] 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).

[0203] 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).

[0204] A drain pipe (360) may be connected to the water storage unit (350). The drain pipe (360) may extend through the drain hole (105) to the machine room (18). 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).

[0205] Below, the ice making unit (40) will be described in detail.

[0206] Fig. 9 is a perspective view showing the arrangement of the first tray unit and the second tray unit of the first embodiment, and Figs. 10 and 11 are perspective views showing the ice making unit and the cooler of the first embodiment. Fig. 12 is a bottom view of the ice making unit according to the first embodiment of the present invention, and Fig. 13 is a cross-sectional view taken along line 13-13 of Fig. 12.

[0207] 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).

[0208] The above ice making unit (40) may include a first tray unit (410) and a second tray unit (450) as described above.

[0209] 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.

[0210] 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.

[0211] 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.

[0212] The above first tray unit (410) may include a first ice-making cell (440).

[0213] 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.

[0214] 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).

[0215] 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).

[0216] 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 other-side cell or the first one-side cell. The first other-side cell may be another one of the first other-side cell and the first one-side 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.

[0217] 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).

[0218] 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).

[0219] 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.

[0220] 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).

[0221] The number of the first openings (423) may be the same as the number of the first ice-making cells (440).

[0222] The first other-side cell (441) can form the other-side outer surface of the first ice. The first one-side cell (442) can form the one-side outer surface of the first ice.

[0223] 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.

[0224] 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.

[0225] 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.

[0226] 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.

[0227] Each of the first other-side cell (441) and the first one-side cell (442) may be formed in a hexahedral shape, for example. The volume of the first other-side cell (441) and the volume of the second other-side cell (442) may be the same or different.

[0228] 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).

[0229] 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.

[0230] 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).

[0231] The above first tray body (420) may include a passage hole (421, 425) for water to pass through.

[0232] The second tray unit (450) may include a second tray forming a second ice-making cell (451).

[0233] 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 a first tray, a left tray, or a first tray section. The second tray (470) may be a second 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.

[0234] 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).

[0235] 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 (272) can be formed in a hemispherical shape, for example.

[0236] 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).

[0237] 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.

[0238] The second ice-making cell (451) may be positioned between the rotation center (C1) of the other side tray (470) and the first ice-making cell (440). The other side tray (470) may be connected to the driving unit (690) by a hinge shaft (489). The hinge shaft (489) may provide the rotation center (C1) of the other side tray (470).

[0239] 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).

[0240] 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).

[0241] 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 one-side tray body (420) and the other-side 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 one-side tray body (420) and the other-side tray body (430).

[0242] 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).

[0243] 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).

[0244] 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).

[0245] 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).

[0246] 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).

[0247] The above-mentioned other side tray (470) may include a second opening (473).

[0248] 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).

[0249] 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.

[0250] 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.

[0251] During the moving process, the other side tray (470) can be moved relative to the one side tray (460).

[0252] 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).

[0253] 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).

[0254] The bracket (452) may be supported on a wall forming the ice making chamber (12). For example, the bracket (452) may be supported on the inner case (101). Alternatively, the bracket (452) may be supported on a separate inner housing accommodated in the inner case (101).

[0255] 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).

[0256] A portion of the one-sided tray (460) may penetrate the bracket (452). Another portion of the one-sided tray (460) may be seated on the bracket (452).

[0257] A driving unit (690) for moving the other side tray (470) may be installed on the above bracket (452).

[0258] 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).

[0259] The above bracket (452) may include a passage hole (634) for water to pass through.

[0260] The second tray unit (450) may further include a supporter (480) that supports the other tray (470).

[0261] 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).

[0262] 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).

[0263] The diameter of the above supporter opening (482a) may be larger than the diameter of the second opening (473).

[0264] 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).

[0265] 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.

[0266] 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.

[0267] 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.

[0268] 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 rotation of the other-side tray (470) is described as an example.

[0269] The second tray unit (450) may further include a case (498) that supports the other side tray (470) from the other side. The case (498) may be mounted on the other side tray (470). At the ice-making position, the one side tray (460) may penetrate the case (498) and come into contact with the other side tray (470).

[0270] For example, the fastening member can be fastened to the supporter (480) by penetrating the case (498) and the other side tray (470).

[0271] 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.

[0272] 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.

[0273] 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.

[0274] 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).

Since the water supplied from the external water source (302) is at room temperature or a temperature similar to room temperature, water can be supplied from the water supply mechanism (320) to the ice making unit (40) during the ice-making process to increase the temperature of the ice making unit (40).

[0309] Fig. 14 is a drawing showing a state in which the first water supply unit and the second water supply unit are separated according to the first embodiment.

The first individual pipe may include, for example, a first pipe (384b), a second pipe (384c), and a third pipe (384d). It should be noted that in the present embodiment, there is no limitation on the number of pipes constituting the first individual pipe. The heights of some of the first pipe (384b), the second pipe (384c), and the third pipe (384d) may be different from the heights of other pipes.

[0324] The first water supply nozzle (381) may be connected to each of the first pipe (384b), the second pipe (384c), and the third pipe (384d). Accordingly, water flowing through the first common pipe (384a) may be distributed to the first pipe (384b), the second pipe (384c), and the third pipe (384d) and then supplied to the first ice-making cell (440) through the first water supply nozzle (381).

[0326] The second water supply unit (382) may include a second water supply pipe (385) through which water flows. The second water supply pipe (385) may receive water from the second pump (362).

[0327] The second water supply unit (382) may further include a second water supply nozzle (383) coupled to the second water supply pipe (385). The second water supply nozzle (383) may spray water into the second ice-making cell (451).

[0328] The second water supply pipe (385) may include a second common pipe (385a). The second common pipe (385a) may extend in the front-rear direction. The second common pipe (385a) may be arranged parallel to the first common pipe (384a).

It should be noted that in the present embodiment, there is no limitation on the number of pipes constituting the second individual pipe. The heights of some of the fourth pipe (385b), fifth pipe (385c), and sixth pipe (385d) may be different from the heights of other pipes.

[0331] The second water supply nozzle (383) may be connected to each of the fourth pipe (385b), the fifth pipe (385c), and the sixth pipe (385d). Accordingly, water flowing through the second common pipe (385a) may be distributed to the fourth pipe (385b), the fifth pipe (385c), and the sixth pipe (385d) and then supplied to the second ice-making cell (451) through the second water supply nozzle (383).

[0332] The second water supply unit (382) may further include a second connection unit (385e) for connection with the first connection unit (384i).

[0333] The second connecting portion (385e) may extend from the second common pipe (385a). For example, a plurality of second connecting portions (385e) may extend toward the first water supply portion (380).

[0334] Either the first connecting portion (384i) or the second connecting portion (385e) can be inserted into the other. For example, FIG. 14 illustrates that the diameter of the second connecting portion (385e) is larger than the diameter of the first connecting portion (384i), so that the first connecting portion (384i) can be inserted into the second connecting portion (385e).

[0335] The second water supply unit (382) may further include a third connection unit (385f) for connection with the connector (386). The third connection unit (385f) may extend from the second common pipe (385a). The third connection unit (385f) may extend from the second common pipe (385a) in the opposite direction to the second connection unit (385e). For example, a plurality of third connection units (385f) may extend toward the connector (386).

[0336] The connector (386) may include a fourth connecting portion (386a) for connection with the third connecting portion (385f). Either the third connecting portion (385f) or the fourth connecting portion (386a) may be inserted into the other. For example, FIG. 14 illustrates that the diameter of the third connecting portion (385f) is larger than that of the fourth connecting portion (386a), so that the fourth connecting portion (386a) may be inserted into the third connecting portion (385f).

[0337] Meanwhile, since at least one of the shape and size of the first ice-making cell (440) is different from the shape and size of the second ice-making cell (451), the structure of the first water supply nozzle (381) and the structure of the second water supply nozzle (383) may be different.

[0338] In this embodiment, water sprayed from one first water supply nozzle (381) can be supplied to a plurality of first ice-making cells (440). On the other hand, water sprayed from one second water supply nozzle (383) can be supplied to one second ice-making cell (451).

[0339] That is, the number of the first water supply nozzles (381) may be less than the number of the first ice-making cells (440). On the other hand, the number of the second water supply nozzles (383) may be the same as the number of the second ice-making cells (451).

[0340] Accordingly, the first water supply nozzle (381) may be called a spray type nozzle. The second water supply nozzle (383) may be called a direct type nozzle.

[0341] The first water supply nozzle (381) can supply water to an open type tray. On the other hand, in the case of the second tray, the second water supply nozzle (383) can supply water to a closed type tray.

[0342] Fig. 15 is a top perspective view of the supporter of the first embodiment, and Fig. 16 is a bottom perspective view of the supporter of the first embodiment.

[0343] Referring to FIGS. 13, 15 and 16, the other side tray (470) may include a other side tray body (471) forming the second other side cell (472).

[0344] The above supporter (480) may include a supporter body (481) that forms a receiving portion (482) for receiving the other side tray body (471).

[0345] The above supporter body (481) may include a body wall (481a) forming the receiving portion (482).

[0346] The upper surface of the above supporter body (481) may be provided with a fastening protrusion (486) for penetrating the other side tray.

[0347] The above supporter (480) may further include a hinge body (483) to which the hinge shaft (489) is coupled. A pair of hinge bodies (483) may be spaced apart in a direction parallel to the extension direction of the hinge shaft (489). A pair of hinge parts (465) may be positioned between the pair of hinge bodies (483).

[0348] The above hinge body (483) may include a shaft hole (484) for the hinge shaft (489) to pass through.

[0349] The above supporter (480) may further include a shaft cover (485) for covering the hinge shaft (489). The shaft cover (485) may be positioned between the pair of hinge bodies (483).

[0350] In order to avoid interference with the hinge shaft (489) when the shaft cover (485) rotates while covering the hinge shaft (489), the shaft cover (485) may be rounded. For example, the shaft cover (485) may be rounded to surround the circumference of the hinge shaft (489) while being spaced apart from the hinge shaft (489).

[0351] During the ice-making process, the shaft cover (485) can be positioned on one side of the hinge shaft (489). Therefore, water can be prevented from splashing toward the hinge shaft (489).

[0352] The above supporter (480) may further include a connecting portion (488) for connecting an elastic member, although this is not shown. The connecting portion (488) may protrude from the side of the supporter body (481).

[0353] The supporter (480) may further include a barrier (487) to prevent water from splashing toward the elastic member connecting portion (488). The barrier (487) may protrude from a side of the supporter body (481). The barrier (487) may be positioned spaced apart from one side of the elastic member connecting portion (488). The protruding length of the barrier (487) may be greater than the protruding length of the elastic member connecting portion (488).

[0354] The above supporter (481) may further include an opening wall (482b) extending around the perimeter of the supporter opening (482a). The opening wall (482b) may be formed in a ring shape or an arc shape.

[0355] The above opening wall (482b) may further include a slot to prevent interference with a component during the icing process. For example, the component may be a pusher.

[0356] The above opening wall (482b) can limit water from splashing outward when water is supplied to the other side tray (470).

[0357] Fig. 17 is a drawing showing the process of supplying water to the ice making unit during the ice making process, Fig. 18 is a drawing showing the process of supplying water from the first water supply unit to the first ice making cell, and Fig. 19 is a drawing showing the process of supplying water from the second water supply unit to the second ice making cell. Fig. 20 is a drawing showing the positional relationship between the supporter and the guide during the ice making process.

[0358] Referring to FIGS. 1 to 20, the process of generating ice in the ice making device (1) will be described.

[0359] 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.

[0360] 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).

[0361] 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.

[0362] After the above water supply process is completed, the ice making process begins.

[0363] In the above ice-making process, water is supplied to the ice-making unit (40) by the water supply unit (330). In addition, in the above ice-making process, the cooling unit operates so that low-temperature refrigerant can flow to the cooler (50).

[0364] In the ice-making process of this embodiment, as water is supplied to each ice-making cell (440, 451), some of the supplied water changes into ice, and as the size of the phase-changed ice increases, ice is created.

[0365] When the above ice making process starts, one or more of the first and second pumps (360, 362) may be operated.

[0366] When the first pump (360) is operated, water can be supplied to the first tray unit (410) through the first water supply unit (380).

[0367] The first water supply nozzle (381) is located on one side of the first tray unit (410). Water sprayed from the first water supply nozzle (381) is supplied to the first ice-making cell (440) of the first tray unit (410).

[0368] Water sprayed from the first water supply nozzle (381) is supplied to the first ice-making cell (440) through the first opening (423) of the first tray body (420). The water supplied to the first ice-making cell (440) flows toward the upper surface of the second tray body (430).

[0369] The water sprayed from the first water supply nozzle (381) can be supplied to a plurality of first ice-making cells (440). Although not limited, the water sprayed from one first water supply nozzle (381) can be supplied to four first ice-making cells (440).

[0370] A portion of the water within the first ice-making cell (440) may be frozen by the first refrigerant pipe (510). 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).

[0371] 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. During the process of water being sprayed onto the one-side tray body (420) or onto the ice created in the one-side tray body (420), air bubbles in the water may be discharged from the water. When air bubbles in the water are discharged from the water, the transparency of the ice created may increase.

[0372] In the above ice-making process, the first ice (I1) can grow to the inner side of the first side cell (441).

[0373] When the second pump (362) is operated, water can be supplied to the second tray unit (450) through the second water supply unit (382).

[0374] The second water supply nozzle (383) may be located on one side of the second tray unit (450). Water sprayed from the second water supply nozzle (383) is supplied to the second ice-making cell (451) of the second tray unit (450).

[0375] Water sprayed from the second water supply nozzle (383) 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).

[0376] As described above, water sprayed from one second water supply nozzle (383) can be directly supplied to one second ice-making cell (451).

[0377] Accordingly, the through hole for water discharge formed in the second water supply nozzle (383) can be aligned vertically with the supporter opening (482a) and the second opening (473).

[0378] The water supplied to the second ice-making cell (451) flows toward the inner surface 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).

[0379] As water is sprayed into the second ice-making cell (451), some of the water freezes. During the process of the water being sprayed onto the one-side tray (460) or onto the ice generated from the one-side tray (460), air bubbles in the water may be discharged from the water. When air bubbles in the water are discharged from the water, the transparency of the ice generated may increase.

[0380] The transparency of the first ice (I1) produced in the first ice-making cell (440) and the transparency of the second ice (I2) produced in the second ice-making cell (451) may be different.

[0381] In the above ice-making process, the second ice (I2) can grow from the side of the one-side tray (460) and grow to the extent of covering one side of the second opening (423a) of the other-side tray (470).

[0382] When the ice-making process is completed, the ice-breaking process is performed. The 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.

[0383] When the above-described ice-making process begins, the flow direction of the refrigerant is switched by the valve so that the high-temperature refrigerant compressed in the compressor (183) can flow to the cooler (50). The high-temperature refrigerant flowing to the cooler (50) can exchange heat with the ice-making unit (40). When the high-temperature refrigerant flows to the cooler (50), heat can be transferred to the ice-making unit (40).

[0384] 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).

[0385] The second ice (I2) can be separated from at least one tray (460) by the heat transferred to the ice making unit (40).

[0386] 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.

[0387] 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. 17).

[0388] 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).

[0389] 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.

[0390] 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).

[0391] During the moving process, the supporter (480) moves in a direction closer to the guide (70), and since the supporter (480) is provided with an inclined surface (481d), interference between the supporter (480) and the guide (70) can be prevented.

[0392] After the other side tray (470) is moved in the forward direction, the other side tray (470) is moved in the reverse direction (counterclockwise in the drawing) by the driving unit (690) so as to come into contact with the one side tray (460).

[0393] 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.

[0394] 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.

[0395] FIG. 21 is a drawing showing water being supplied to an ice making unit according to a second embodiment, and FIG. 22 is a bottom perspective view of a second tray unit according to the second embodiment.

[0396] Fig. 23 is a perspective view of a supporter according to the second embodiment. Fig. 24 is a drawing showing a second water supply unit according to the second embodiment installed on the supporter, and Fig. 25 is a cross-sectional view taken along line 25-25 of Fig. 24.

[0397] This embodiment is otherwise identical to the first embodiment, with the exception of the second water supply section. Therefore, only the modified structure related to the second water supply section will be described, and the description of the first embodiment will be used for the same configuration as the first embodiment.

[0398] Referring to FIGS. 21 to 25, unlike the first embodiment, in the second embodiment, the second water supply unit (1382) can be mounted on the second tray unit (450).

[0399] A water supply tube (373) connected to the second water supply unit (1382) may be connected to the second connecting pipe (372). The water supply tube (373) may be formed of a material whose shape can be changed.

[0400] For example, the second water supply unit (1382) may be installed on a supporter (480a) and moved together with the supporter (480a).

[0401] The other side tray (470) may include a other side tray body (471) forming a second other side cell (472). The other side tray (470) may further include a tray extension portion (475) extending in the second direction from the other side tray body (471).

[0402] The above supporter (480a) may include a supporter body (481) that forms a receiving portion (482) for receiving the other side tray body (471).

[0403] The supporter body (481) may include a body wall (481a) forming the receiving portion (482). The body wall (481a) may be formed, for example, in a hemispherical shape or a shape similar to a hemisphere. The supporter opening (482a) may be formed in the body wall (481a).

[0404] The supporter body (481) may further include a body extension (481b) extending from the body wall (481a). The tray extension (475) may be mounted on the body extension (481b).

[0405] The case (498) can be mounted on the tray extension (475) mounted on the body extension (481b). The case (498) can include a case opening (498a) through which the one-sided tray (470) passes.

[0406] The case (498) may further include a fastening hole (498b) through which a fastening member may pass. The fastening member may pass through the fastening hole (498b) and the tray extension (475) and be fastened to the supporter (480a).

[0407] The supporter body (481) may further include a peripheral wall (481c) extending from the body wall (481b). The peripheral wall (481c) may be spaced apart from the body wall (481a). Accordingly, a space (485) for accommodating the second water supply unit (1382) may be formed between the peripheral wall (481c) and the body wall (481a).

[0408] The above-mentioned peripheral wall (481c) may be provided with an inclined surface (481d) to prevent interference with the guide (70) during the movement of the supporter (480a) during the moving process.

[0409] The supporter (480a) may further include an opening wall (482b) extending around the supporter opening (482a). The opening wall (482b) may be formed in a ring shape or an arc shape.

[0410] The above supporter (480a) may further include a hinge body (483, 483a) to which the shaft (489) is coupled. A plurality of hinge bodies (483, 483a) may be spaced apart in a direction parallel to the extension direction of the shaft (489).

[0411] The above hinge body (483, 483a) may include a shaft hole (484) through which the hinge shaft (489) passes.

[0412] Meanwhile, the second water supply unit (1382) may include an inlet pipe (1384). The inlet pipe (1384) may be connected to the water supply tube (373). Although not limited, the inlet pipe (1384) may be formed in a straight shape or may be bent one or more times.

[0413] The inlet of the above inlet pipe (1384) can be referred to as the first through hole.

[0414] The above second water supply unit (1382) may further include a common pipe (1385) connected to the inlet pipe (1384).

[0415] The above common pipe (1385) may, for example, extend in a direction parallel to the arrangement direction of the second ice-making cell (451).

[0416] The above common pipe (1385) can be fastened to the above supporter (480a).

[0417] For example, the common pipe (1385) may be located in the space (485) between the peripheral wall (481c) and the body wall (481a).

[0418] The common pipe (1385) may be formed with a protruding fastening rib (1387). The supporter (480a) may be provided with a fastening portion (486) for fastening to the fastening rib (1387). The fastening portion (486) may be positioned, for example, between two adjacent second side cells (472).

[0419] The above-mentioned fastening portion (486) may protrude from the supporter (480a). A fastening protrusion (486a) aligned with the fastening rib (1387) may be provided at the end of the above-mentioned fastening portion (486). A portion of the fastening protrusion (486a) may be inserted into the fastening rib (1387). In this state, a fastening member may be fastened to the fastening rib (1387) and the fastening protrusion (486a).

[0420] The above peripheral wall (481c) may be provided with a pipe opening (481e) for the inlet pipe (1384) to pass through.

[0421] The second water supply unit (1382) may further include one or more supply pipes (1386) extending from the common pipe (1385).

[0422] The number of the above supply pipes (1386) may be the same as the number of the second ice-making cells (251).

[0423] The common pipe (1385) may be positioned radially outside the supporter opening (482a). The supply pipe (1386) may extend from the common pipe (1385) and be aligned with the supporter opening (482a). The supply pipe (1386) may extend from the common pipe (1385) toward the center of the supporter opening (482a).

[0424] The above supply pipe (1386) can be aligned with the second opening (473).

[0425] Although not limited, the supply pipe (1386) may be located in the center of the second opening (473).

[0426] A slot (482c) may be formed in the above opening wall (482b) for the supply pipe (1386) to pass through. The slot (482c) may prevent the supply pipe (1386) from interfering with the above opening wall (482b).

[0427] The above supply pipe (1386) may include a water supply hole (1386c) (or a second through hole). The above water supply hole (1386c) may be referred to as a second through hole.

[0428] The above water supply hole (1386c) can be arranged so that water is supplied into the second ice-making cell (251) via the second opening (473) formed in the other side tray (470).

[0429] For example, the water supply hole (1386c) may be located in the support opening (482a) or in the second opening (473). The water supply hole (1386c) may be located in the center of the second opening (473) or may correspond to the center.

[0430] The diameter of the above-mentioned water supply hole (1386c) may be smaller than the diameter of the second opening (473). Therefore, a portion of the water supplied to the second ice-making cell (251) may flow downward through the outer region of the water supply hole (1386c) from the second opening (473). In addition, the water supplied through the water supply hole (1386c) may be prevented from interfering with the water discharged from the second ice-making cell (251) through the second opening (473).

[0431] When the above water supply hole (1386c) is located in the support opening (482a) or the second opening (473), water can be stably supplied into the second ice-making cell (251), so the size of the second opening (473) can be reduced.

[0432] In this embodiment, the position of the supporter (480a) can be changed during the ice-making and ice-removing processes. Accordingly, the position of the supply pipe (1386) mounted on the supporter (480a) can also be changed.

[0433] Since the other side tray (470) is mounted on the supporter (480a), the supply pipe (1386) can move in the same direction as the movement direction of the other side tray (470).

[0434] The supply pipe (1386) may include, but is not limited to, a first portion (1386a) extending from the common pipe (1385). The supply pipe (1386) may further include a second portion (1386b) extending from the first portion (1386a) and bent at one point.

[0435] In another aspect, the second water supply unit (1382) of the present embodiment may be understood to include a first through hole (inlet of the inlet pipe), a second through hole (1386c), and a connecting pipe connecting the first through hole and the second through hole (1386c). In this case, the connecting pipe may include at least a portion of the inlet pipe, a common pipe, and at least a portion of the discharge pipe.

[0436] Meanwhile, the water supply tube (373) connected to the inlet pipe (1384) may extend in a direction parallel or nearly parallel to the arrangement direction of the second ice-making cells (251).

[0437] Among the plurality of hinge bodies (483, 483a), one hinge body (483a) may be provided with a rib (484a) for fixing the position of the water supply tube (373). The rib (484a) may extend from the hinge body (483a). The water supply tube (373) may be positioned between the hinge body (483a) and the rib (484a). The rib (484a) may be extended to be rounded or bent one or more times to form a space in which the water supply tube (373) may be positioned.

[0438] According to the present embodiment, when the supporter (480a) moves, the water supply tube (373) also moves together, and if the water supply tube (373) is positioned close to the hinge body (483a) that provides the center of rotation of the supporter (480a), the bending phenomenon of the water supply tube (373) can be minimized.

[0439] Fig. 26 is a perspective view of the pusher of the second embodiment.

[0440] Referring to FIG. 22 and FIG. 26, the pusher (490a) of the present embodiment can be mounted on the bracket (452).

[0441] The above bracket (452) may include an inclined wall (455). The pusher (490a) may be mounted on the inclined wall (455), for example.

[0442] A mounting groove (455a) for mounting the pusher (490a) may be formed on the inclined wall (455).

[0443] The above pusher (490a) may include a plate (491) that is seated in the seating groove (455a). The pushing bar (492) may extend from the plate (491).

[0444] A fastening protrusion (456) may be formed in the above-mentioned fixing groove (455a). The above-mentioned plate (491) may be provided with a protrusion hole (495) through which the fastening protrusion (456) passes. Although not limited, the protrusion hole (495) may be located between two adjacent pushing bars (492).

[0445] A fastening boss (457) may be formed in the above-mentioned fixing groove (455a). A boss engaging portion (496) to which the fastening boss (457) is engaged may be provided in the above-mentioned plate (491). The boss engaging portion (496) may protrude from the above-mentioned plate (491). The fastening boss (457) may be inserted into the boss engaging portion (496). In this state, a fastening member may be fastened to the boss engaging portion (496) and the fastening boss (457).

[0446] The pusher (490a) may be positioned on one side of the other tray (470). The pusher (490a) may provide a path (493) that allows the component to move through the interior. The path (493) may be formed on the pushing bar (492).

[0447] The above pusher (490a) may further include a wall (493d) that provides a position at which a component passing through the empty space (493b) stops. The wall (493d) may include a hole (494).

[0448] Although not limited, the component may be a part of the second water supply unit (1382). For example, the component may be the supply pipe (1386).

[0449] In another aspect, the pusher (490a) may include an opening through which a component may move.

[0450] The above opening may be formed on one side of the pusher (490a). At least a portion of the above component may be disposed on one side of the pusher (490a), and the above opening may be formed on one side of the pusher (490a).

[0451] Alternatively, at least a portion of the above components may be disposed on one side of the pusher (490a), and the opening may be formed on one side of the pusher (490a).

[0452] The above opening may be provided to face a non-opening wall, so that the part may be stopped by the wall.

[0453] Fig. 27 is a drawing showing a connector being coupled to a first water supply unit according to the second embodiment.

[0454] Referring to FIG. 27, the first water supply unit (380) and connector (386) of the present embodiment may be the same as the first water supply unit and connector mentioned in the first embodiment.

[0455] However, the first water supply unit (380) and the connector (386) may be connected by an intermediate member (2385). The intermediate member (2385) may be positioned corresponding to the second water supply unit in the first embodiment.

[0456] The intermediate member (2385) may include a first connection part (2386) for connection with the first water supply unit (380). The intermediate member (2385) may include a second connection part (2387) for connection with the connector (386).

[0457] As another example, it is also possible to omit the intermediate member (2385), in which case the first water supply unit (380) may be directly connected to the connector (386).

[0458] Fig. 28 is a drawing showing a process in which water is supplied to an ice making unit during an ice making process according to the second embodiment.

[0459] Referring to FIG. 28, the process for generating ice in the present embodiment may include a water supply process. The process for generating ice may further include an ice-making process. The process for generating ice may further include an ice-breaking process.

[0460] 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).

[0461] 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.

[0462] After the above water supply process is completed, the ice making process begins.

[0463] In the above ice-making process, the pumps (360, 362) can be turned on simultaneously or sequentially.

[0464] 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).

[0465] 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).

[0466] When the second pump (362) is operated, water can be supplied to the second tray unit (450) through the second water supply unit (382).

[0467] Water sprayed from the second water supply unit (1382) can be supplied to the second ice-making cell (451) through the supporter opening (482a) of the supporter (480a) and the second opening (473) of the other tray (470).

[0468] In the present embodiment, since the second water supply unit (1382) is mounted on the supporter (480a), water can be supplied intensively to the second ice-making cell (451).

[0469] Once the ice-making process is complete, the ice-breaking process can be performed.

[0470] When the above-described ice-making process begins, the high-temperature refrigerant compressed in the compressor (183) can flow to the cooler (50). The high-temperature refrigerant flowing to the cooler (50) can exchange heat with the ice-making unit (40). When the high-temperature refrigerant flows to the cooler (50), heat can be transferred to the ice-making unit (40).

[0471] 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).

[0472] 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). 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.

[0473] Next, the driving unit (690) can be operated so that the second ice (I2) is separated from the second tray unit (450).

[0474] That is, after the second ice is created in the second ice-making cell (251), the controller can cause the other tray (470) to move in the first direction (clockwise with reference to FIG. 28) to the ice-removing position in order to remove ice from the second ice-making cell (251). The controller can control the other tray (470) to move in the second direction after moving in the first direction.

[0475] As the other side tray (470) is rotated to the ice position, the pusher (490a) presses the other side tray (470), so that the second ice (I2) can be separated and dropped from the other side tray (470).

[0476] Alternatively, depending on the size of the second opening (473), the pusher (490a) may penetrate the other side tray (470) to directly press the second ice (I2). Alternatively, the pusher (490a) may contact both the other side tray (480) and the second ice (I2).

[0477] During the moving process, the second water supply unit (1382) can move in a direction closer to the pusher (490a).

[0478] As described above, since the pusher (490a) includes a path (393), the second water supply unit (1382) can move without interference with the pusher (490a) during the moving process. For example, the supply pipe (1386) can move while being accommodated in the pushing bar (492).

[0479] After the other side tray (470) is rotated in the first direction, the other side tray (470) can be rotated in the second direction (counterclockwise in the drawing) by the driving unit (690) to come into contact with the one side tray (460).

[0480] FIG. 29 is a bottom perspective view of a second tray unit according to a third embodiment, FIG. 30 is a drawing showing the other side tray and supporter and the second water supply unit according to the third embodiment, and FIG. 31 is a bottom perspective view of the other side tray according to the third embodiment.

[0482] This embodiment is otherwise identical to the second embodiment, with the exception of the second water supply section. Therefore, only the modified structure related to the second water supply section will be described, and the description of the second embodiment will be used for the same configuration as the second embodiment.

[0483] Referring to FIGS. 29 to 33, the second water supply unit (3382) of the present embodiment may be mounted on the second tray unit (450a). For example, the second water supply unit (3382) may be mounted on the supporter (1480).

[0484] A water supply tube (373) may be connected to the second water supply unit (3382). The water supply tube (373) may be formed of a material whose shape can be changed.

[0485] The other side tray (1470) of the present embodiment may include a other side tray body (1471) forming a second other side cell (472). The other side tray (1470) may further include a tray extension portion (1473) extending from the other side tray body (1471). A fastening boss (1475) for coupling a fastening member for fastening with the supporter (1480) may be formed on the tray extension portion (1473). A fastening hole (1475a) may be formed at a position corresponding to the fastening boss (1475).

[0486] The above supporter (1480) may include a supporter body (1481) that forms a receiving portion (1482) for receiving the other side tray body (1471). A supporter opening (1482a) may be formed in the supporter body (1481).

[0487] The supporter body (1481) may include a body wall (1481a) forming the receiving portion (1482). The body wall (1481a) may be formed, for example, in a hemispherical shape or a shape similar to a hemisphere. The supporter opening (1482a) may be formed in the body wall (1481a).

[0488] The supporter body (1481) may further include a body extension portion (1481b) extending from the body wall (1481a). The tray extension portion (1473) may be mounted on the body extension portion (1481b). The body extension portion (1481b) may include a fastening protrusion portion (1487a) aligned with the fastening boss (1475). A fastening member penetrating the fastening boss (1475) may be fastened to the fastening protrusion portion (1487a).

[0489] The supporter body (1481) may further include a peripheral wall (1481c) extending from the body wall (1481b). The peripheral wall (1481c) may be spaced apart from the body wall (1481a). The peripheral wall (1481c) may be provided with an opening (1481e) through which a portion of the second water supply unit (3382) passes.

[0490] The above supporter (1480) may be provided with a fastening portion (1486) for fastening to the second water supply portion (3382). The fastening portion (1486) may, for example, protrude from the body wall (1481a).

[0491] The second tray unit (450a) of the present embodiment may further include a heater (1490: see FIG. 35). The heater (1490) may provide heat to the other tray (470) during the ice-making process. The second ice may be separated from the other tray (1470) by the heat provided from the heater (1490).

[0492] The heater (1490) may be coupled to, for example, the other side tray (1470). The other side tray (1470) may further include a heater coupling portion (1476) to which the heater (1490) is coupled. The heater coupling portion (1476) may be formed, for example, on the other side tray body (1471). The heater coupling portion (1476) may extend along the perimeter of the second opening (473).

[0493] The heater coupling portion (1476) may protrude from the other side tray body (1471). The heater coupling portion (1476) may include a receiving groove (1477) for receiving the heater (1490). The receiving groove (1477) may be formed by recessing one surface of the heater coupling portion (1476).

[0494] The heater (1476) accommodated in the above-described receiving groove (1447) may surround the second other-side cell (472). For example, the heater (1476) may surround the second other-side cell (472). Accordingly, a portion of the heater (1476) may be rounded, thereby increasing the contact area between the heater (1476) and the other-side tray (1470).

[0495] The above-mentioned receiving groove (1447) may include, for example, a curved portion (1447a) and a straight portion (1477b).

[0496] The above heater joint (1476) may further include a slot (1478) for passage of the heater (1490).

Fig. 37 is a cross-sectional view taken along line 37-37 of Fig. 36, and Fig. 38 is a cross-sectional view taken along line 38-38 of Fig. 36.

[0498] In Figures 37 and 38, the supporter is omitted.

[0499] Referring to FIGS. 34 to 38, the second water supply unit (3382) may include an inlet pipe (3383). The inlet pipe (3383) may be connected to the water supply tube (373) described in the second embodiment. Although not limited, the inlet pipe (3383) may be formed in a straight shape or may be bent one or more times.

[0500] The inlet of the above inlet pipe (3383) can be referred to as the first through hole.

[0501] The above inlet pipe (3383) can pass through the opening (1481e) of the peripheral wall (1481c).

[0505] The second water supply unit (3382) may further include a discharge opening (3392) through which water supplied to the second ice-making cell (451) passes. To prevent interference between water sprayed from the water supply hole (3391) to the second ice-making cell (451) and water discharged through the discharge opening (3392), the water supply hole (3391) may be aligned with the second opening (473) of the other tray (470). The discharge opening (3392) may be located on the side of the water supply hole (3391). For smooth flow of water, the second water supply unit (3382) may include a plurality of discharge openings (3392). For example, the water supply hole (3391) may be located between two discharge openings (3392). The size of the above discharge opening (3392) may be larger than the diameter of the above water supply hole (3391).

[0506] The above second water supply unit (3382) can be coupled to the supporter (1480) to cover the supporter opening (1482a).

[0511] Accordingly, the second body (3388) may be formed in a shape corresponding to the heater coupling portion (1476). For example, the second body (3388) may include a curved portion (3387a) and a straight portion (3387b).

[0512] The above-mentioned coupling body (3386) may include a slot (3393) for the heater (1490) to pass through.

[0513] The above-described coupling body (3387) may further include a coupling extension portion (3389) for coupling to the supporter (1480). For example, a plurality of coupling extension portions (3389) may extend from the second body (3388). The coupling extension portions (3389) may, for example, extend from the curved portion (3387a). A coupling hole (3389a) for a coupling member to pass through may be formed in the coupling extension portion (3389). The coupling hole (3389a) may be aligned with the coupling portion (1486) of the supporter (1480).

Accordingly, one surface of the protrusion (3390) may be rounded on one side. One side of the above protrusion (3390) can form a second side cell (472) in a hemispherical shape together with the other side tray body (471).

[0515] Since the protrusion (3390) is located in the second opening (473), the discharge opening (3392) can pass through the protrusion (3390) in the vertical direction so that water inside the second other cell (472) can pass through.

[0516] The protrusion (3390) may be spaced apart from the second body (3388). The protrusion (3390) may be positioned between a pair of curved portions in the second body (3388).

[0517] Meanwhile, when the other side tray (1470) is seated on the supporter (1480), the heater coupling portion (1476) can pass through the supporter opening (1482a). The heater coupling portion (1476) can protrude through the supporter opening (1482a). The heater (1490) can be coupled to the heater coupling portion (1476).

[0518] When the second water supply unit (3382) is coupled to the supporter (1480), the coupling body (3386) can surround the heater coupling unit (1476). At this time, a portion of the heater (1490) can be arranged to surround the outer periphery of the protrusion (3390).

[0522] Then, one side portion of the second ice can be separated from the one side tray (460). The other side portion of the second ice can be separated from the other side tray (1470).

[0523] When the operation of the above heater (1490) is completed, the above movement process can be performed.

[0524] In the above moving process, the supporter (1480) can be moved clockwise in the drawing by the driving unit (690). In the present embodiment, since the second ice can be separated from the other tray (1470) by the heater (1490), the pusher of the second embodiment can be omitted.
