[0105] The ice maker and / or the refrigerator may include a heater. The heater (e.g., a wire heater, cable heater, radiant heater, etc.) may supply heat to the compartment and / or the storage compartment. The heater may directly supply heat to the tray assembly and / or the compartment. Alternatively, the heater may indirectly supply heat (e.g., hot air, warm air) without contacting the tray assembly and / or the compartment.

[0106] The ice maker and / or the refrigerator may include a cooler (e.g., evaporator, refrigerant pipe, refrigerant valve, fan, damper, thermoelectric module, etc.). The cooler may be in contact with the tray assembly and / or the compartment to directly supply cold air. The cooler may also provide heat indirectly (e.g., cold air, cold flow) without being in contact with the tray assembly and / or the compartment.

[0107] The ice maker and / or the refrigerator may include a temperature sensor. The temperature sensor can be used to detect the temperature of items (e.g., water) or ice in the compartment.

[0108] The ice maker and / or the refrigerator may include a drive mechanism. The drive mechanism may be connected to the tray assembly and / or the pusher.

[0109] The refrigerator of the present invention may include a tray assembly forming part of a compartment that serves as a space for water to change into ice, a cooler for supplying cold air to the compartment, a water supply unit for supplying water to the compartment, and a controller. The refrigerator may further include a drive unit capable of moving the tray assembly. In addition to the compartment, the refrigerator may further include a storage compartment for storing food. The refrigerator may further include a cooler for supplying cold air to the storage compartment. The refrigerator may further include a temperature sensor for detecting the temperature inside the storage compartment. The controller may control at least one of the water supply unit and the cooler. The controller may control at least one of the heater and the drive unit.

[0110] The controller can be configured to, after moving the tray assembly to the ice-making position, supply cold air to the compartment via the cooler. The controller can also be configured to, after ice has been formed in the compartment, move the tray assembly in a forward direction to the ice-removal position to remove the ice from the compartment. The controller can further be configured to, after ice removal, move the tray assembly in a reverse direction to the water supply position and then begin water supply. Finally, the controller can be configured to, after water supply is complete, move the tray assembly back to the ice-making position.

[0111] In this invention, the compartment is located inside the storage chamber and can be defined as the space where water changes phase to ice. The periphery of the compartment refers to its outer surface, regardless of its shape. Alternatively, the outer periphery of the compartment can refer to the inner surface of the wall forming the compartment. The center of the compartment refers to its center of gravity or center of volume. The center may pass through the line of symmetry of the compartment.

[0112] In this invention, a tray can be defined as a wall that divides the interior of the compartment and the storage room. The tray can be defined as a wall that forms at least a portion of the compartment. The tray can be configured to completely or partially surround the compartment.

[0113] In this invention, the refrigerator may include at least one tray assembly configured to be connected to and movable by a drive unit. The drive unit is configured to move the tray assembly along at least one of the X, Y, and Z axes, or to rotate it around at least one of the X, Y, and Z axes. This invention may include a refrigerator having all the components described in the specific embodiments except for the drive unit and the power transmission member connecting the drive unit and the tray assembly. In this invention, the tray assembly can move in a first direction.

[0114] In this invention, the refrigerator may include at least one tray assembly configured with the heater. The heater may be configured near the tray assembly to heat the compartment formed by the tray assembly with the heater. The heater may include a heater (hereinafter referred to as a "transparent ice heater") controlled to turn on in at least a portion of the area where the cooler supplies cold flow, so as to cause dissolved air bubbles in the water inside the compartment to move from the ice-forming portion to the liquid water side to form transparent ice.

[0115] In this invention, the compartment can be cooled by the cooler that cools the storage room. As an example, the storage room containing the compartment is a freezer that can be controlled at a temperature below 0 degrees Celsius, and the compartment can be cooled by the cooler that cools the freezer.

[0116] In this invention, the compartment can be cooled by a different cooler than the cooler of the storage compartment. For example, the storage compartment containing the compartment is a refrigerator compartment with a temperature that can be controlled above 0 degrees Celsius, and the compartment can be cooled by a different cooler than the cooler of the refrigerator compartment. That is, the refrigerator has a refrigerator compartment and a freezer compartment, the compartment is located inside the refrigerator compartment, and the compartment can be cooled by the cooler that cools the freezer compartment. The compartment can be located at the door of the storage compartment for opening and closing.

[0117] In this invention, the degree of deformation resistance represents the extent to which an object resists deformation caused by an external force applied to it, and is defined as a value determined by factors such as the object's shape, material, and thickness.

[0118] On the other hand, from the perspective of the material of the object, the high resistance to deformation can refer to the high rigidity of the object. The thermal conductivity can be an inherent material property of the object. Even when the materials of the objects are the same, the resistance to deformation can vary depending on the shape of the object, etc. The resistance to deformation can be affected by the deformation-resistant reinforcement extending in the direction in which the external force is applied. The greater the rigidity of the deformation-resistant reinforcement, the greater the resistance to deformation. The higher the height of the extended deformation-resistant reinforcement, the greater the resistance to deformation.

[0119] In this invention, the degree of restoration refers to the extent to which an object deformed by an external force returns to its original shape before the external force was applied after the external force is removed. It is defined as a value determined by factors such as the object's thickness, material, etc.

[0120] On the other hand, from the perspective of the object's material, the degree of resilience of the object can refer to the object's high elastic modulus. The elastic modulus can be an inherent material property of the object. Even when objects are made of the same material, the degree of resilience can vary depending on the object's shape, etc.

[0121] Hereinafter, specific embodiments of the refrigerator of the present invention will be described with reference to the accompanying drawings.

[0122] Figure 1 This is a diagram illustrating a refrigerator according to an embodiment of the present invention.

The freezer compartment 32 can be divided into two spaces even if it can be opened and closed using a single door 30.

[0126] In this embodiment, the freezer compartment 32 can be referred to as the first storage compartment, and the refrigerator compartment 18 as the second storage compartment. An ice maker 200 capable of making ice can be installed in the freezer compartment 32. As an example, the ice maker 200 can be located in a portion of the space of the freezer compartment 32 (e.g., the upper space).

[0127] An ice box 600 may be disposed on one side (e.g., the lower side) of the ice maker 200, into which the ice produced by the ice maker 200 falls and is stored. The user can remove the ice box 600 from the freezer compartment 32 and use the ice stored in it. The ice box 600 may be attached to one side (e.g., the upper side) of the wall separating the first space (e.g., the upper space) and the second space (e.g., the lower space) of the freezer compartment 32.

[0128] Although not shown, the housing 14 is provided with a conduit (not shown) for supplying cold air to the ice maker 200. The conduit guides the cold air, after heat exchange with the refrigerant flowing in the evaporator, toward the ice maker 200. As an example, the conduit may be positioned in one direction (e.g., rearward) of the housing 14, discharging cold air in another direction (e.g., frontward). The ice maker 200 may be positioned in one direction of the conduit (e.g., frontward). The outlet of the conduit may be located on one or more of the first side wall (e.g., rear side wall) and the second side wall (e.g., upper side wall) of the freezer compartment 32, but is not limited thereto.

[0129] The above description uses the example of the ice maker 200 being installed in the freezer compartment 32 as an example. However, the space in which the ice maker 200 can be installed is not limited to the freezer compartment 32; the ice maker 200 can be located in various spaces capable of receiving cold air. The following description uses the example of the ice maker 200 being located in the storage compartment as an example.

[0139] A cold flow hole 226a may be formed in any of the walls 222b to allow the cold flow passing through the ice maker to be discharged.

[0140] A switch hole 226b may be formed on any of the walls 222b, and a switch for inputting commands regarding the opening / closing of the ice maker is configured in the switch hole 226b.

[0141] The other wall 222a of the two second walls 222 can function as a preventive plate to prevent ice falling into the ice box 600 or ice stored in the ice box 600 from spilling outwards.

[0142] The bracket 220 may include a third wall 223 protruding from the first wall 221. The third wall 223 may protrude from the first wall 221 toward the storage compartment. The third wall 223 may include a first member 223a extending in a direction corresponding to one direction of the storage compartment (e.g., front-rear direction) and a second member 223b extending from one end (e.g., front end) of the first member 223a in another direction (e.g., left-right direction). The third wall 223 may include a hook 223c that engages with one side (e.g., top surface) of the storage compartment. As an example, the hook 223c may be provided on the second member 223b.

[0143] The second component 223b may provide a water supply section 248. The water supply section 248 may guide water supplied from the upper side to one side (e.g., the lower side) of the water supply section 248. A water supply pipe (not shown) may be arranged on the other side (e.g., the upper side) of the water supply section 248.

[0144] Since the water supply unit 248 is positioned lower than the water supply pipe, water will not splash onto the water supply unit 248 but will be guided in one direction (e.g., downwards). Furthermore, due to the lower height, even if the water moves in one direction (e.g., downwards), the amount of water splashing can be reduced.

[0145] The water supply unit 248 may include a first water supply member 248a connected to the second member 223b of the third wall 223 and a second water supply member 248b having an inclined surface extending from the first water supply member 248a in one direction (e.g., downward).

[0146] The water supply unit 248 may include a third water supply unit 248c extending on both sides of the second water supply member 248b to prevent the supplied water from splashing to the outside.

[0147] The two third water supply components 248c extend from the first water supply component 248a in one direction (e.g., rearward) and can be tilted such that the separation distance between the two third water supply components 248c decreases in one direction (e.g., rearward).

[0148] The support 220 may have a suction port 224a for the cold air from the storage compartment to flow into the tray assembly. The suction port 224a may be formed on the side wall of the support 220.

[0149] As an example, the suction hole 224a may be formed in the space between the second wall 222 and the third wall 223.

[0150] From another perspective, the suction hole 224a may be formed by at least a portion of the second wall 222 penetrating through it.

[0151] Cold air is drawn from the side of the bracket 220 through the suction hole 224a into the tray assembly side, which can serve as a cold air flow for ice making.

[0152] The support 220 may include a blocking plate 227a, which prevents the cold flow drawn in through the suction hole 224a from flowing out of the support 220 instead of flowing to the tray assembly.

[0153] As an example, the blocking plate 227a may extend from the first wall 221 in one direction (e.g., upward). The blocking plate 227a is separated laterally from the suction hole 224a, and a plurality of compartments 411a may be disposed between the suction hole 224a and the blocking plate 227a.

[0154] The plurality of said compartments 411a may be arranged along a direction (e.g., the X-axis direction).

[0155] The end (e.g., the upper end) of the compartment 411a can be open. That is, the compartment 411a has an open end through which water can be supplied.

[0156] The blocking plate 227a is positioned further away from the suction port 226a than the compartment 411a furthest from the suction port 226a, thereby preventing cold flow from bypassing multiple compartments 411a and being discharged from the support 220.

[0157] The support 220 may include a fourth wall 225 for engagement with the pusher 540. The fourth wall 225 may extend from one end (e.g., the rear end) of the first wall 221 in one direction (e.g., downward) to form a wall of one side (e.g., the back side) of the support 220.

[0158] The fourth wall 225 may include guide protrusions 225a for guiding wires connected to the ice maker. A plurality of guide protrusions 225a may be provided.

[0159] The ice maker 200 may include a tray assembly.

[0160] The pallet assembly may include a pallet 400, or may include pallet housings 450 and 480, or may include the pallet 400 and pallet housings 450 and 480.

[0161] The support 220 can define at least a portion of the space for accommodating the tray assembly.

[0162] The ice maker 200 may include a compartment 411a that serves as a space for water to change phase into ice through a cold flow. A plurality of compartments 411a may be formed.

[0163] The tray 400 can form the compartment 411a.

[0164] The tray 400 can be movably configured. The tray 400 can move linearly or rotate.

[0165] If water is cooled by a cold flow while water is being supplied to the compartment 411a, ice of the same or similar shape as the compartment 411a can be generated. As an example, the compartment 411a may have a polyhedral or cubic shape with an open top.

[0166] The tray 400 can be referred to as an "open-loop shape tray".

[0167] As an example, the pallet housing may include a pallet cover 480 and a pallet support 450. The pallet cover 480 and the pallet support 450 may be integrally formed, or they may be combined after being manufactured as separate components.

[0168] In this embodiment, the tray cover 480 and the tray support 450 can be combined after being manufactured as separate components. As an example, the second tray 400, the second tray support 450, and the second tray cover 480 can be combined using fastening members.

[0169] At least a portion of the tray cover 480 may be located on one side (e.g., the upper side) of the tray 400.

[0170] The ice maker 200 may include a pusher 540. As an example, the pusher 540 may be attached to the bracket 220. The pusher 540 may be referred to as a "fixed pusher".

[0171] The pusher 540 can push out ice located in the compartment 360. As an example, the pusher 540 can pass through the tray support 450 and contact the tray 400 forming the compartment 411a, and can press the contacted tray 400.

[0172] The pusher 540 may include a connecting plate 542 that engages with the bracket 220 and at least one push rod 544 disposed on the connecting plate 542. A plurality of push rods 544 may be connected to the connecting plate 542 in a separate manner along a first direction (for example, the horizontal direction).

[0173] The push rods 544 may be provided in the same number as the number of compartments 411a, but are not limited thereto.

[0174] The ice maker 200 may include a heater 490.

[0175] The heater 490 is disposed in the heater housing 460 and can apply heat to the tray 400.

[0176] The heater 490 may be configured to be adjacent to or in contact with an end (e.g., lower end) of the tray 400 to supply heat to a portion (e.g., lower part) of the tray 400.

[0177] The heater 490 is operable to assist in the formation of transparent ice during the ice-making process. The heater 490 may be referred to as a "transparent ice heater".

[0178] As an example, the heater 490 may be a wire heater.

[0179] The heater housing 460 is disposed at one end (e.g., the lower end) of the tray support 450, and the heater 490 disposed on one side (e.g., the top surface) of the heater housing 460 may be disposed at one end (e.g., the lower end) of the tray 400.

[0180] The ice maker 200 may include a drive unit 510 that provides driving force. The tray 400 may receive the driving force from the drive unit 510 to move.

[0181] The drive unit 510 may include a motor and a plurality of gears.

[0182] The drive unit 510 can be connected to a full ice detection rod 470. The full ice detection rod 470 is moved by the power provided by the drive unit 510, and during the movement, it detects the amount of ice stored in the ice box 600.

[0183] A push rod connection portion 515, which is connected to the full ice detection rod 470, can be provided on the side of the drive unit 510.

[0184] The drive unit 510 may include a cam that receives power from the motor to move or rotate. The ice maker 200 may include a sensor that detects the movement or rotation of the cam.

[0185] As an example, a magnet is provided on the cam, and the sensor can be a Hall sensor used to detect the magnetism of the magnet during the movement of the cam. Depending on whether the magnet is detected by the sensor, the sensor can output a first signal and a second signal as mutually different outputs. Either the first signal or the second signal can be a high-level signal, and the other signal can be a low-level signal.

[0186] The refrigerator controller can determine the position of the tray 400 (or the second tray assembly) based on the type and pattern of signals output by the sensors. That is, since the tray 400 and the cam are moved by the motor, the position of the tray 400 can be indirectly determined based on the detection signal of the magnet set on the cam.

[0187] As an example, the water supply location, ice-making location, and ice-moving location can be distinguished and determined based on the signal output by the sensor.

[0188] The tray support 450 may include a protrusion 459 connected to the drive unit 510. The protrusion 459 may be configured to protrude from one side (e.g., the side) of the tray support 450 toward the drive unit 510.

[0189] Figure 7 This is a front perspective view of the tray according to an embodiment of the present invention. Figure 8 This is a rear perspective view of the tray according to an embodiment of the present invention. Figure 9 This is a top view of the tray according to an embodiment of the present invention. Figure 10 It is along Figure 8 A sectional view taken along line 10-10. Figure 11 This is a cross-sectional view showing the configuration of the compartment walls of a tray according to an embodiment of the present invention.

[0190] Reference Figures 7 to 11 The tray 400 in this embodiment of the invention may include a tray wall 410 forming the compartment 411a.

[0191] The tray wall 410 may include compartment walls 411 that define the outer periphery of each compartment 411a. A plurality of compartment walls 411 may be provided corresponding to a plurality of compartments 411a.

[0192] In order to form separate ice, the compartment walls 411 can be separated or formed apart along a direction (e.g., the X-axis direction).

[0193] by Figure 7 Based on this, we can understand the X-axis as the left-right direction, the Y-axis as the front-back direction, and the Z-axis as the up-down direction.

[0194] The tray 400 may include a separation wall 413 for separating or dividing a plurality of the compartments 411a. The separation wall 413 may be provided between two adjacent compartments 411a.

[0195] The plurality of said compartment walls 411 can be separated by said separation wall 413.

[0196] The separation wall 413 can form one side of each of the compartments 411a.

[0197] The separation wall 413 can be provided in a plurality of separate parts along a direction (e.g., the X-axis direction).

[0198] With reference to the end (e.g., the lower end) of the tray wall 410 or the compartment wall 411, the height of the separation wall 413 can be formed differently along the length direction of the compartment. It can be understood that the length direction is a direction (e.g., the Y-axis direction).

[0199] The separation wall 413 may include a first wall member 413a, which includes the highest portion of the separation wall 413.

[0200] The first wall member 413a can form a first height H1 from the end (e.g., the lower end) of the tray wall 410.

[0201] The first wall 413a can be connected to the fourth extension wall 433.

[0202] The separation wall 413 may include a second wall member 413b formed at a lower height than the first wall member 413a. The second wall member 413b may extend from the first wall member 413a toward the second extension wall 431.

[0203] The second wall member 413b can form a channel for water flow when water diffuses from any one compartment 411a to other surrounding compartments 411a during water supply.

[0204] The height of the second wall member 413b can be configured as a second height H2 that is lower than the first height H1. Because the second wall member 413b has a relatively low height, water flow (water diffusion) between compartments 411a can be achieved smoothly.

[0205] The separating wall 413 may include a third wall member 413c that connects the first wall member 413a and the second wall member 413b.

[0206] The third wall member 413c can extend obliquely from the first wall member 413a toward the second wall member 413b.

[0207] The separation wall 413 may include a fourth wall member 413d extending from the second wall member 413b and connected to the tray wall 410.

[0208] The thickness of the fourth wall member 413d in one direction (e.g., the X-axis direction) can be greater than the thickness of the first wall member 413a or the second wall member 413b in one direction (e.g., the X-axis direction). The strength of the separation wall 413 can be enhanced by the configuration of the fourth wall member 413d.

[0209] Since the third wall member 413d includes a portion with increased thickness, it is easy to form the desired polyhedral shape.

[0210] The tray 400 may include a first extension wall 420 extending from the upper end of the tray wall 410 in a first direction (for example, a horizontal direction). The first extension wall 420 may extend from the periphery of one side (e.g., the upper side) end of the tray wall 410 in the first direction (for example, a horizontal direction).

[0211] The first extended wall 420 may include a wall body 421. The wall body 421 is disposed at the edge of the plurality of compartments 411a and may protrude from the edge of the plurality of compartments 411a in a first direction (for example, the horizontal direction).

[0212] The tray 400 may include engagement holes 423, 424 for engaging with the tray support 450 or the tray cover 480.

[0213] The connecting holes 423 and 424 may include a first connecting hole 423 that engages with the tray support 450. A protrusion 457 of the tray support 450 may be inserted into the first connecting hole 423.

[0214] The first mating hole 423 can be aligned with the cover hole 483 of the tray cover 480 in one direction (e.g., up and down).

[0215] The first connecting hole 423 can be formed in multiples.

[0216] The connecting holes 423 and 424 may include a second connecting hole 424 that engages with the tray cover 480. A protrusion 484 of the tray cover 480 can be inserted into the second connecting hole 424.

[0217] The tray 400 may include a peripheral wall 430 surrounding a plurality of the compartments 411a. The peripheral wall 430 may protrude from the first extension wall 420 in one direction (e.g., upward).

[0218] The peripheral wall 430 may extend along the periphery of the end (e.g., the upper end) of the tray wall 410. As an example, the peripheral wall 430 may be integrally formed with the tray wall 410 and extend upward from the end (e.g., the upper end) of the tray wall 410.

[0219] The inner space of the peripheral wall 430 can form a fluid flow space when water is supplied from the water supply unit 248.

[0220] The peripheral wall 430 may include a second extension wall 431 that protrudes from the first extension wall 420 in one direction (e.g., upward). The second extension wall 431 may include the portion of the peripheral wall 430 that protrudes most from the first extension wall 420.

[0221] In the water supply position, the tray 400 is in a state of forward movement at a predetermined angle. In order to prevent water from overflowing outside the tray 400 when water is supplied in this position, the second extension wall 431 can extend from the first extension wall 420 to a relatively high position.

[0222] The second extension wall 431 may be configured adjacent to the side end of the tray 400 that moves in one direction (e.g., downward) as it moves from the water supply position.

[0223] By adjusting the height of the second extension wall 431, even if one side of the tray 400 moves in one direction (e.g., downwards), the end of the second extension wall 431 (e.g., the upper end) can be located at a position higher than the water level.

[0224] The second extended wall 431 can guide the movement of water as it diffuses from one compartment 411a to adjacent compartments 411a. That is, the inner surface of the second extended wall 431 can form a water guiding surface.

[0225] The second extension wall 431 can form at least a portion of the flow path (waterway) for fluid supplied to the compartment 411a.

[0226] The second extension wall 431 may be disposed on the side of the compartment wall 411 connected to the third wall member 413c of the separation wall 413.

[0227] The peripheral wall 430 may include a third extension wall 432 that is bent or folded from both sides of the second extension wall 431 and extends in a direction (e.g., the Y-axis direction).

[0228] The third extension wall 432 may protrude from the first extension wall 420 in a direction (e.g., upward).

[0229] The third extension wall 432 may extend obliquely in a direction in which the height of the wall decreases.

[0230] The third extension wall 432 may form at least a part of a flow path (water path) of the fluid supplied to the compartment 411a.

[0231] The second extension wall 431 and the third extension wall 432 may have the shape of a bent or curved wall (a U-shaped).

[0232] The peripheral="17"]]The peripheral wall 430 may include a fourth extension wall 433 that is connected to the third extension wall 432 and forms at least a part of the edge of the compartment 411a.

[0233] A part of the fourth extension wall 433 and the second extension wall 431 may be arranged on opposite sides with the compartment 411a as the center.

[0234] The fourth extension wall 433 may protrude from the first extension wall 420 in a direction (e.g., upward).

[0235] The height at which the second extension wall 431 protrudes from the first extension wall 420 in a direction (e.g., upward) may be greater than the height at which the third extension wall 432 protrudes from the first extension wall 420 in a direction (e.g., upward).

[0236] The height at which the third extension wall 432 protrudes from the first extension wall 420 in a direction (e.g., upward) may be greater than the height at which the fourth extension wall 433 protrudes from the first extension wall 420 in a direction (e.g., upward).

[0237] The fourth extension wall 433 may include a first member 433a that defines at least a part of the edge of one compartment 411a among the plurality of compartments 411a and a second member 433b that defines at least a part of the edge of another compartment 411a.

[0238] The third extension wall 433 may include a third member 433c that connects the first member 433a and the second member 433b and has a shape that is recessed in the direction toward the compartment 411a.

[0239] The third component 433c can be connected to the first wall component 413a of the separation wall 413.

[0240] Temperature sensors 428 for detecting the temperature of water or ice in compartment 411a may be configured in the space between the plurality of compartment walls 411.

[0241] The temperature sensor 428 may be configured to contact or be adjacent to the outer surface of the compartment wall 411. As an example, the temperature sensor 428 may be configured to contact the outer surface of one compartment wall 411 and the outer surface of another compartment wall 411 among a plurality of compartment walls 411.

[0242] At least one of the compartment walls 411 and the other compartment wall 411 may be formed with a sensor mounting slot 411c for configuring the temperature sensor 428 (see reference). Figure 28 The locking step 414 can be defined by the sensor setting slot 411c.

[0243] The temperature sensor 428 is configured to have a length along one direction (e.g., the Y-axis direction) of the tray 400 and can be configured to pass through the centerline of one direction (e.g., the front-to-back direction) of the compartment 411a.

[0244] The compartment 411a can be defined by the compartment wall 411.

[0245] The inner surface of the compartment wall 411 can form the compartment surface 412 of the compartment 411a.

[0246] The compartment surface 412 may include a first compartment surface 412a that defines the bottom surface of the compartment 411a.

[0247] The compartment surface 412 may include a second compartment surface 412b extending upward from one end of the first compartment surface 412a, i.e., toward the open end (e.g., the upper end) of the compartment 411a.

[0248] The second compartment surface 412b may form part of the compartment wall 411 (e.g., the front portion).

[0249] The second compartment surface 412b may extend obliquely in one direction (e.g., upward) from one end of the first compartment surface 412a so that the width of the compartment 411a in the first direction (e.g., front and back) can increase upward.

[0250] The compartment surface 412 may include a third compartment surface 412c extending from the other end of the first compartment surface 412a toward the open end (e.g., the upper end) of the compartment 411a.

[0251] The third compartment surface 412c may form part of the compartment wall 411 (e.g., the rear portion).

[0252] The third compartment surface 412c may extend obliquely in one direction (e.g., upward) from the other end of the first compartment surface 412a, so that the width of the compartment 411a in the first direction (e.g., front and back) can increase in one direction (e.g., upward).

[0253] The third compartment surface 412c may include a surface facing the second compartment surface 412b.

[0254] The compartment surface 412 may include a fourth compartment surface 412d forming one side (e.g., a side) of the compartment 411a. The fourth compartment surface 412d may extend from both sides of the first compartment surface 412a in one direction (e.g., upward).

[0255] The fourth compartment surface 412d can extend obliquely from both sides of the first compartment surface 412a in one direction (e.g., upward) so that the width of the compartment 411a in the second direction (e.g., left and right sides) can increase upward.

[0256] The fourth compartment surface 412d can form one side of the separation wall 413.

[0257] The tray 400 may be formed of a non-metallic material. For example, the tray 400 may be formed of a flexible or soft material that can deform in shape when pressed by the pusher 540. For example, the tray 400 may be formed of silicone, but is not limited thereto.

[0258] Therefore, during the pressing of the tray 400 by the pusher 540, the tray 400 can transfer the pressing force of the pusher 540 to the ice while deforming. Under the pressing force of the pusher 540, the ice and the tray 400 can separate.

[0259] When the tray 400 is formed of a non-metallic material, a flexible material, or a soft material, the bonding or adhesion between the ice and the tray 400 can be reduced, so that the ice can be easily separated from the tray 400.

[0260] When the tray 400 is formed of a non-metallic material, a flexible material, or a soft material, after the tray 400 is deformed by the pusher 540, if the pressing force of the pusher 540 is removed, the tray 400 can easily return to its original shape.

Figure 17 This is a partial perspective view illustrating a case where a pallet is supported by a pallet support member according to an embodiment of the present invention. Figure 18 It is along Figure 16 A sectional view taken along line 18-18.

[0262] Reference Figures 12 to 18 The ice maker 200 of this embodiment may include a tray support 450 that supports the tray 400.

[0263] At least a portion of the tray support 450 may be located on one side (e.g., the underside) of the tray 400.

[0264] The tray support 450 can support the tray 400 from one side (e.g., the underside). As an example, at least a portion of the tray wall 410 forming the compartment 411a of the tray 400 can be supported by the tray support 450.

[0265] The pallet support 450 may include a first wall 451 forming its outer surface. The first wall 451 may include at least one of the front wall 451a, back wall 451b, first side wall 451c, second side wall 451d, top wall 451e, and bottom wall 451f of the pallet support 450. The front wall, back wall, first side wall, second side wall, top wall, and bottom wall may be referred to sequentially as "the first to the sixth walls".

[0266] By means of the configuration of the first wall 451, the tray support 450 can have a hexahedral shape with a first end (e.g., the upper end) and a second end (e.g., the lower end) open.

[0267] A through hole 450a may be formed on the inner side of the tray support 450 for the tray 400 to be disposed. If the tray 400 is disposed in the through hole 450a, a portion (e.g., the upper part) and another portion (e.g., the lower part) of the tray 400 may be exposed to the outside of the tray support 450.

[0268] The tray support 450 may include partitions 452 that separate the plurality of compartment walls 411 of the tray 400.

[0269] The partition 452 can extend from one end (e.g., the front end) of the through hole 450a toward the other end (e.g., the rear end). One end of the partition 452 can be connected to one side of the inner circumferential surface of the tray support 450 that defines the through hole 450a, and the other end of the partition 452 can be connected to the other side of the inner circumferential surface of the tray support 450.

[0330] Reference Figures 24 to 28The ice maker 200 of this embodiment may include a heater housing 460. A heater 490 may be disposed in the heater housing 460. The heater housing 460 may be combined with the tray support 450.

[0331] The heater housing 460 may include a housing body 461, with a heater 490 for transferring heat from one side (e.g., the underside) of the tray 400 disposed on the housing body 461. The housing body 461 may include a heater groove 461a that accommodates at least a portion of the heater 490.

[0332] The housing body 461 may form an opening 462. A portion of one end (e.g., the lower end) of the tray 400 can be inserted into this opening 462. A plurality of openings 462 may be provided corresponding to a plurality of compartments 411a, and these openings 462 may be arranged along a direction (e.g., the X-axis). For example, the opening 462 may be circular. However, its shape is not limited.

[0333] At least a portion of the heater slot 461a may be formed along the outer periphery of the opening 462.

[0334] The heater housing 460 may include protrusions 463 extending from the housing body 461. A plurality of protrusions 463 may be provided along the periphery of the housing body 461.

[0335] The protrusion 463 is aligned with the protrusion 458 of the tray support 450, and the specified fastening member can be fastened to the protrusion 463 and 458.

[0336] The heater housing 460 may include a support protrusion 465 for supporting a temperature sensor 428. The support protrusion 465 may include a support surface that protrudes from the housing body 461 and contacts or is located adjacent to the support protrusion 465. The support protrusion 465 prevents the temperature sensor 428 from detaching from the tray 400. The support protrusion 465 may be located among a plurality of the openings 462.

[0337] The heater 490 may be configured along the periphery of the opening 462 at a position that contacts or is adjacent to the tray 400.

[0338] The heater 490 may include a first member 491 extending along the periphery of the opening 462. As an example, the first member 491 may be bent or extend in an arc shape corresponding to the shape of the opening 462.

[0339] The first component 491 may be provided with a plurality of openings 462 corresponding to the plurality of openings 462.

[0340] The heater 490 may include a second member 492 connecting a plurality of the first members 491. The second member 492 may include portions connected to both ends of the first members 491. The second member 492 may include a linearly extending portion. The second member 492 may extend on both sides of the support protrusion 465 and connect two adjacent first members 491.

[0341] The first component 491 and the second component 492 can be integrally formed.

[0342] Reference Figure 28 The heater 490 may be configured in contact with the tray 400 or may be configured adjacent to the tray 400.

[0343] The heater 490 may be configured at the end (e.g., the lower end) of the tray 400.

[0344] As an example, the heater 490 may be configured at the end (e.g., the lower end) of the compartment wall 411 that forms the first compartment surface 412a.

[0345] The first component 491 of the heater 490 may be disposed at an end (e.g., the lower end) of the compartment wall 411. Since a plurality of compartment walls 411 are provided, a plurality of the first component 491 may be provided and disposed at the end (e.g., the lower end) of each compartment wall 411.

[0346] The second component 492 of the heater 490 may be configured to pass through a separate space between the first compartment wall 411 and the second compartment wall 412 of a plurality of compartment walls, and connect to a plurality of the first components 491.

[0347] The refrigerator's controller can be configured to enable the heater 490 to heat the compartment 411a during at least a portion of the interval in which cold air is supplied to the compartment 411a, thereby generating transparent ice.

[0348] By utilizing the heat of the heater 490 to delay the ice formation rate, dissolved air bubbles in the water inside the compartment 411a move from the ice-forming part to the liquid water side, thereby enabling the formation of transparent ice in the ice maker 200. That is, dissolved air bubbles in the water can also be guided to escape to the outside of the compartment 411a or trapped at a predetermined location within the compartment 411a.

[0349] On the other hand, if ice is generated quickly when cold flow is supplied to the compartment 411a, the air bubbles dissolved in the water inside the compartment 411a may freeze without moving from the part where ice is generated to the liquid water side, which may result in low transparency of the generated ice.

[0350] Conversely, if the rate of ice formation is slow when supplying cold flow to the compartment 411a, while the above-mentioned problem is solved and the transparency of the formed ice is increased, it may cause the problem of longer ice-making time.

[0351] Therefore, the heater 490 can be configured on one side (e.g., the lower side) of the compartment 411a and locally heat the compartment 411a to improve the transparency of the generated ice while reducing the delay in ice-making time.

[0352] Reference Figure 29 and Figure 30 A heater housing 460 is disposed on the underside of the tray 400, and a portion of one end (e.g., the lower end) of the tray 400 is exposed to the outside through the opening 462.

[0353] When the heater housing 460 is separated, the end (e.g., the lower end) of the tray 400 is exposed to the outside, and the tray 400 is located inside the through hole 450a of the tray support 450.

[0354] Reference Figure 31 The tray 400 can be placed on one side (e.g., the upper side) of the heater housing 460.

[0355] As an example, the heater 490 may be disposed in the heater housing 460 and accessiblely disposed at the end (e.g., the lower end) of the tray 400.

[0356] A heater groove may be formed at the end (e.g., the lower end) of the tray 400 to accommodate at least a portion of the heater 490, so as to maintain the contact state between the tray 400 and the heater 490.

[0357] To distinguish it from the heater slot 461a of the heater housing 460, the heater slot 461a can be referred to as the "first heater slot", and the heater slot of the tray 400 can be referred to as the "second heater slot".

[0358] A space for arranging temperature sensors 428 can be formed between a plurality of the compartment walls 411. A step 414 for supporting the temperature sensors 428 can be provided on the side of the compartment wall 411 that forms the second compartment surface 412b or the third compartment surface 412c.

[0359] The temperature sensor 428 is disposed between the step 414 of the first compartment wall 411 and the step 414 of the adjacent second compartment wall 411, and can be supported by the partition 452 of the tray support 450. The temperature sensor 428 is prevented from detaching from the heater housing 460 by the support protrusion 465 of the heater housing 460.

[0360] The temperature sensor 428 can be located in the space between the partition 452 and the support protrusion 465. As described above, the heater 490 is configured adjacent to the end (e.g., the lower end) of the tray 400 and is able to supply heat to the compartment 411a, thus facilitating the production of transparent ice.

[0361] The temperature sensor 428 is disposed in the space defined by the tray 400, the tray support 450 and the heater housing 460 and is configured adjacent to the tray 400, thus enabling easy detection of the temperature of water or ice present in the compartment 411a.

[0362] Figures 32a to 32e This is a diagram illustrating the operation of an ice maker according to an embodiment of the present invention.

[0363] Reference Figure 32a When the tray assemblies 400, 450, and 480 are in the water supply position, the tray 400 can be positioned by the drive unit 510 at a forward movement set angle θ1. For example, the set angle can be a value within the range of 20° to 25° to prevent overflow.

[0364] Since water is supplied while the tray 400 is moving in the forward direction at the set angle, water can easily diffuse into the plurality of compartments 411a.

[0365] During water supply, water from the water supply section 248 can flow into compartment 411a through the open side (e.g., the upper side) of the tray 400.

[0366] At this time, water can be supplied to the second extension wall 431 of the tray 400 and can diffuse along the second extension wall 431 in one direction (e.g., the X-axis direction). The diffused water can be distributed to a plurality of compartments 411a. As an example, water can be supplied to the compartment 411a near the central side of the plurality of compartments 411a, and the water can diffuse to the other adjacent compartments 411a.

[0367] The inner surface of the second extension wall 431 may include a guiding surface for guiding the flow of water.

[0368] The second wall member 413b of the separation wall 413 can form part of the waterway through which water flows to the adjacent compartment 411a.

[0369] After the preset amount of water is supplied, a set time can be waited for the water to diffuse from the central compartment 411a to the side compartments 411a.

[0370] When the water supply is completed, the water level can be located at a position lower than the second wall member 413b of the separation wall 413.

[0371] Figure 32b This shows the ice maker in the ice-making position. (Refer to...) Figure 32b When the tray assembly is in the ice-making position, the tray 400 can be moved in the opposite direction from the water supply position and kept horizontal by the drive unit 510.

[0372] At the ice-making position, cold air can be supplied to the compartment 411a via the open upper part of the tray 400 through the cold air supply device, in which ice I can be generated.

[0373] In the ice-making process, the heater 490 can be driven to generate transparent ice.

[0374] Figure 32c The diagram shows the process of moving ice from the ice maker. Figure 32d This shows the situation where the ice maker reaches the maximum ice-moving position.

[0375] Reference Figure 32c and Figure 32d After ice making is complete, the drive unit 510 can move forward.

[0376] When the drive unit 510 moves forward, such that the tray 400 is in the maximum ice-moving position, the end of the tray 400 (e.g., the lower end) can contact and deform with the pusher 540. The ice present in the tray 400 can be pressed by the pusher 540 and separated from the tray 400.

[0377] The second tray 400 may be formed of a flexible or soft material that can deform in shape when pressed by the pusher 540.

[0378] During the ice removal process, the heater 490 can be activated to assist in the smooth removal of ice from compartment 411a.

[0379] Ice detached from the tray 400 can fall and be stored in the ice box 600. After the ice removal operation is completed, the drive unit 510 can be operated to move the tray assembly in the opposite direction and reset it to the ice-making position. Figure 32b ).

[0380] If the water supply operation begins, the tray assembly can move toward the water supply position ( Figure 32a(Moves forward.) At the water supply position, fluid is supplied through the water supply unit 240, and the fluid can be supplied to a plurality of compartments 411a.

[0381] An additional embodiment for controlling water supply will be described.

[0382] To control the water supply, a sensor for detecting the water level can be installed on the support 220 or the compartment wall 411. For example, the sensor could be a temperature sensor or a capacitance sensor.

[0383] exist Figure 32a After the water supply is completed at the water supply location, Figure 32b When the ice-making position moves, the water level can be detected by the sensor.

[0384] If the sensor determines that the water level is low, the system moves back to the water supply position and adds the set minimum water supply. This process is repeated until the desired water level is detected, at which point the system can proceed. Figure 32b The following are the ice-making steps.

[0385] On the other hand, when the sensor is composed of a temperature sensor, during water supply, the temperature sensor can detect the water level based on the result of detecting a temperature above zero when in contact with water.

[0386] After the ice removal is complete, wait until the temperature detected by the temperature sensor reaches below zero before supplying water. This is to prevent false detections when the temperature sensor detects a temperature above zero after ice removal, as the temperature difference between the ice-removed and water-supplyed temperatures is minimal upon contact with water above zero.
