Description

[AREA]

[0001] Embodiments of the present disclosure relate to a device for producing powdered ice. [BACKGROUND]

[0002] A powder ice or shaved ice maker is an electrical device designed to produce shaved ice flakes that resemble snow. Unlike ice cubes, shaved snow has the advantage of a short production time and high heat exchange efficiency.

[0003] Such a device for producing powdered ice or shaved ice can be classified into a type with a rotating ice-making drum and a type with a stationary ice-making drum.

[0004] A conventional device for producing powdered ice of the type with a rotating ice-making drum is disclosed in Korean patent number 10-0809928, which includes a rotating ice-making drum, a cooling cycle for cooling the ice-making drum, a water tank containing water in which the ice-making drum is partially immersed, and a cutting blade for cutting the ice, which is in contact with the outer circumferential surface of the ice-making drum, into scraped ice.

[0005] Meanwhile, a conventional device for producing ice of the type with a fixed ice-making drum is disclosed in Korean patent number 10-1446901, which includes a stationary ice-making drum having a freezing system, a water spray unit designed to spray water onto an inner wall of the ice-making drum while rotating inside the ice-making drum, and a cutting unit designed to produce shaved ice by cutting the ice produced from the sprayed water.

[0006] The powder ice production device with a rotating ice-making drum has a rotating ice-making drum, so that the refrigerant supplied to an evaporator provided in the ice-making drum could leak out. The charge level of the compressor provided in the ice-making drum for producing ice can vary according to the amount of water stored in the water tank or the conditions near the water tank.

[0007] However, the conventional device for producing powdered ice of the type with a fixed ice-making drum has a further disadvantage: the unfrozen water sprayed by the water spray component can fall into an ice compartment designed only to receive the cut ice, causing the ice to melt or clump. Another disadvantage is that the water is not sprayed uniformly onto the inner wall of the ice-making drum, or water sprayed onto a lower area of ​​the inner wall can flow downwards after failing to be converted into ice.

[0008] KR 20 1995 0 006 397 Y1 discloses a crushed ice maker comprising a fresh water supply unit for refilling the supplied water and an ice-making unit configured to produce ice by forcibly drawing water from said supply unit. The maker further comprises a cutting unit for scraping the produced ice, a dispensing unit for discharging the crushed ice to the outside, and a mechanical unit configured to compress and condense refrigerant, which is connected to an evaporator of the ice-making unit. DETAILED DESCRIPTION OF THE INVENTIONAL PROBLEM

[0009] To overcome the disadvantages, it is an objective of the present invention to solve the problems described above and others and to provide a device for producing powdered ice or a device for producing scraped ice which can prevent unfrozen water from melting the scraped ice by preventing the unfrozen water from falling onto the scraped ice.

DESCRIPTION OF SPECIFIC EXECUTION FORMS

[0030] Exemplary embodiments of this disclosure are described in detail below with reference to the accompanying drawings. Regardless of the numerical references, identical or equivalent components may be provided with the same reference numbers, and their descriptions will not be repeated. For the sake of a concise description with reference to the drawings, the sizes and profiles of the elements shown in the accompanying drawings may be exaggerated or reduced in size, and it is understood that the embodiments presented here are not limited by the accompanying drawings.

[0031] The terminology used in this disclosure is used only to describe certain embodiments and is not intended to limit this disclosure.

[0032] With reference to the in Fig. In the orthogonal coordinate system shown, a positive direction of the X-axis is defined as a front direction (forward) and a negative direction of the X-axis as a back direction (or backward). Similarly, a positive direction of the Z-axis is defined as an up direction (upward) and a negative direction of the Z-axis as a down direction (downward). A positive direction of the Y-axis is defined as a right direction (to the right) and a negative direction of the Y-axis as a left direction (to the left).

[0033] Fig. Figure 1 is a perspective view of a device for producing scraped ice according to an embodiment of the present disclosure. Fig. Figure 2 is a perspective exploded view of the device for producing scraped ice.

[0034] As in Fig. 1 and Fig. As shown in Figure 2, the device for producing shaved ice according to the embodiment comprises an ice-making component 100, which is designed in the form of a cylinder; a shaft 200, which is rotatable on a central axis of the ice-making component 100; a water spray component 300, which is provided in the shaft 200 and is configured to spray water onto an inner wall of the ice-making component 100 during rotation; a cutting component 400, which is provided in the shaft 200 and is configured to cut the ice produced on the inner wall of the ice-making component 100 during rotation; a water compartment 500, which is provided below the water spray component 300 while it rotates at the same angle as the shaft 200; and an ice compartment 600, which is provided below the cutting component 400.

[0035] The device for producing shaved ice is of the stationary ice-making drum type. The water spray component 300 and the cutting component 400 produce powdered or shaved ice while rotating within the ice-making component 100. The water that is not converted into ice can fall into the water compartment 500 and be stored there. The powdered or shaved ice cut from the inner wall of the ice-making component 100 can fall into the ice compartment 600 and be stored there. Thus, the shaved ice (SI) and the unfrozen water are kept separate to prevent the unfrozen water from melting the shaved ice (SI).

[0036] The device for producing shaved ice according to the illustrated embodiment can be manufactured as a module. The shaved ice production module can be integrated into an electrical household appliance, such as a refrigerator, a water purifier, or similar device, and can produce the shaved ice. Alternatively, the shaved ice production module can be provided as a standalone electrical household appliance to form a device for producing and producing the shaved ice.

[0037] The structure and elements of the device for producing scraped ice are described in detail below.

[0038] Fig. Figure 3 is a sectional view showing the device for producing scraped ice in a horizontal view, and Fig. Figure 4 is a sectional view showing the device for producing scraped ice in a vertical view.

[0039] With reference to Fig. 3 and Fig. 4 The ice-making component 100 has a metal cylinder area 102; and a coolant tube 104 for ice-making, which covers an outer circumferential area of ​​the cylinder area 102.

[0040] The cylinder section 102 can be made of a metal with high thermal conductivity 102 to exchange heat with the coolant tube 104 of the ice-making device, which cools the ice to a low temperature in a relatively short time. A central axis of the cylinder section 102 is vertically oriented, and the top and bottom of the cylinder section 102 are open.

[0041] An inner circumferential surface of the cylinder area 102 can directly absorb the water sprayed by the water spray component 300, and the ice produced on the inner circumferential surface of the cylinder area 102 can be cut into scraped ice (SI) by the cutting component 400. In other words, the inner circumferential surface of the cylinder area 102 can form an inner wall of the ice-making component 100.

[0042] The coolant tube 104 for ice production can be wound around the outer circumferential surface of the cylinder area 102 in a diagonal direction to form a spiral shape.

[0043] The coolant flowing through the coolant pipe 104 for ice production is directed to a lower section of the cylinder section 102 and discharged from an upper section of the cylinder section 102. An inlet end 106 of the coolant pipe 104 for ice production can be provided in the lower section of the cylinder section 102, and an outlet end 108 of the coolant pipe 104 for ice production can be provided in the upper section of the cylinder section 102.

[0044] If the cooling capacity of the cooling circuit (for example, the capacity of the compressor 110) is insufficient, the temperature of the coolant at the outlet end 108 is relatively higher than at the inlet end 106. Accordingly, the lower part of the cylinder area 102 is provided at a lower temperature than the upper part.

[0045] Even if the water sprayed by the water spray component 300 falls along the inner circumferential surface of the cylinder area 102, ice can be generated in the lower area of ​​the cylinder area 102, whose temperature is lower in this respect than that of the upper area, in order to minimize only the unfrozen water that falls from the cylinder area 102.

[0046] The coolant pipe 104 for ice production can function as an evaporator for cooling the cylinder area 102 and the water sprayed onto the inner circumferential surface of the cylinder area 102. The cooling circuit system includes an evaporator 104, a compressor 110, a condenser 112, and an expansion valve 114.

[0047] The high-temperature, high-pressure gas refrigerant compressed in compressor 110 is circulated and condensed in condenser 112 to become a liquid refrigerant at a relatively low temperature. The liquid refrigerant circulates and expands in expansion valve 114. The expanded, low-temperature, low-pressure liquid refrigerant is then circulated from expansion valve 114 into evaporator 104, where it evaporates to become gaseous. The gaseous refrigerant is then supplied to compressor 110. As the liquid refrigerant evaporates and becomes gaseous in evaporator 104, heat is removed from the periphery of the evaporator, thus producing a cooling effect in its vicinity.

[0048] In this case, the inlet end 106 is connected to the expansion valve 114 and the outlet end 108 of the coolant pipe 104 for ice making is connected to the compressor 110.

[0049] Meanwhile, the device for producing scraped ice can further include a housing 161 designed to retain the cold air generated in the coolant tube 104 for ice production, in order to minimize the heat exchange between the outside air and the coolant tube 104 for ice production.

[0050] The housing 116 can cover the outer circumferential surface of the cylinder area 102 and form an enclosed space (C). The coolant pipe 104 for ice production is located within this enclosed space (C). This minimizes the leakage of cold air generated in the coolant pipe 104 for ice production and the heat exchange between the coolant pipe 104 and the outside air.

[0051] The housing 116 includes a housing cylinder section 116a, the diameter of which is larger than the diameter of the cylinder section 102; and covers 116b and 116c designed to cover the space formed between the housing cylinder section 116a and the cylinder section 102. In this case, the covers 116b and 116c comprise an upper cover 116b and a lower cover 116c, respectively, designed to cover the top and bottom of the housing cylinder section 116a and the cylinder section 102. Accordingly, the enclosed space (C) can be defined by the cylinder section 102, the housing cylinder section 116a, the upper cover 116b, and the lower cover 116c.

[0052] The ice-making coolant pipe 104 refers to a pipe surface located within the enclosed space (C). The inlet end 106 and the outlet end 108 of the ice-making coolant pipe 104 refer to a pipe surface located outside the housing 116. In other words, the inlet end 106 passes through a lower portion of the housing 116, and the outlet end of the ice-making coolant pipe 104 passes through an upper portion of the housing 116.

[0053] Meanwhile, the device for producing shaved ice can also include a fastening component 700 for securing the housing 116 or the ice-making component 100. The fastening component 700 for securing the housing 116 is described below for simplicity, and this can also be applied to securing the ice-making component 100.

[0054] The fastening component 700 includes a mounting plate 701, which is intended to fasten the housing 116; and a base plate 704, which is provided under the mounting plate 702, which is spaced at a certain distance from it.

[0055] The housing 116 is held on the upper side of the mounting plate 702 by a flange that projects from an outer circumferential surface of the housing 116 beyond the mounting plate 702. The flange 118 and the mounting plate 702 are fastened together by means of a screw to secure the housing 116 to the mounting plate.

[0056] A multitude of supports can be provided between the mounting plate 702 and the base plate 704, and both ends of each support 706 can be fastened to the mounting plate 702 and the base plate 704.

[0057] Meanwhile, the device for producing scraped ice can still include a drive unit 800 designed to generate a driving force in order to rotate the shaft 200.

[0058] The drive unit 800 can be located in an upper or lower region of the shaft 200. Since the water compartment 500 and the ice compartment 600 are located below the shaft 200, it is preferred that the drive unit 800 be located above the shaft 200.

[0059] The drive unit 800 comprises a drive motor 802, which is supplied with an electric current and is designed to generate a rotational force; a drive gear 802 connected to the drive motor 802; and a shaft gear 804 attached to the shaft 200. The shaft gear 804 engages with the drive gear 806 and receives the rotational force designed to rotate the shaft 200. Alternatively, the drive gear 804 can also include an auxiliary transmission gear 808, which is provided between the shaft gear 804 and the drive gear 806, in order to receive the rotational force and rotate the shaft 200 by exerting this rotational force. In this case, the shaft gear 804, the transmission gear 808, and the drive gear 806 have diameters that decrease in that order.

[0060] If the drive unit 800 is provided above the shaft 200, an upper plate 708 may also be provided to secure the drive unit 800.

[0061] The upper plate 708 is spaced upwards at a specific distance from the mounting plate 702, and the plurality of supports 706 can be provided between the mounting plate 702 and the upper plate 708 to hold the upper plate 708. The upper portion of the housing 116, which passes through the upper plate 708 and the shaft 200 rotatably on the central axis of the housing 116 (or the ice-making component 100), can project upwards from a top surface of the mounting plate 702 to be connected to the shaft gear 804.

[0062] Fig. 5 is a sectional view showing a first state of the device for producing scraped ice, and Fig. Figure 6 is a sectional view showing a second state of the device for producing scraped ice.

[0063] Regarding the water spray direction in the first state of the device for producing scraped ice, the water spray direction in the second state is rotated 180° relative to the first state. In other words, the difference between the first and second states is the reversal of the direction in which the shaft is rotated 180° to the right or left.

[0064] With reference to Fig. 5 and Fig. 6 The water spray component 300 can include a tube 302 which is attached to one side of the shaft 200 and is designed to supply water; and a through opening 304 which is designed to spray water flowing along the tube 302 outwards.

[0065] The pipe 302 can be inserted through the opening 202 provided in the shaft 200. The pipe 302 provided in the opening 202 can be connected to one side of a connector (not shown), and a water supply hose (not shown), connected to an external water supply source, is connected to the other side of the connector (not shown). Accordingly, even if the pipe 302 attached to the shaft 200 is rotated, water from the external water supply source can be supplied to the pipe 302 without it being twisted by the connector.

[0066] The through-hole 304, which is provided as an opening through the tube 302, can adjust the diameter of the through-hole or the number of through-holes 304 based on the quantity or pressure of the water sprayed onto the inner circumferential surface of the cylinder section 102. An additional nozzle (not shown) can be provided in the through-hole 304. However, the diameter of the tube 302 and the sprayed water cannot be so large that it is preferable to provide the nozzle (not shown) when the diameter of the cylinder section 102 becomes larger, in order to produce solid scraped ice.

[0067] The water can be sprayed from the water spray component 300 from an area higher than half the height (h) of the ice-making component 100. In other words, the water is sprayed downwards from the area higher than half the height (h) of the cylinder section 102. The through-hole 304 or nozzle (not shown) can be located higher than half the length of the tube 302 within the cylinder section 102.

[0068] The water sprayed onto the upper part of the cylinder area 102 is more likely to condense and become ice as it falls along the inner circumferential surface of the cylinder area 102. However, the water sprayed onto the lower part of the cylinder area 102 falls along the inner circumferential surface in a relatively short time, and the heat exchange with the ice-making component 100 can therefore be relatively brief. It is more likely that the unsprayed water will become the unfrozen water that falls from the ice-making component 100.

[0069] The water spray component 300 can be positioned longitudinally along the shaft 200 and configured to spray water onto the inner circumferential surface of the ice-making component 100. The water spray component 300 can spray vertically in the direction of the inner circumferential surface.

[0070] Meanwhile, the device for producing scraped ice can further include a guide 310 which is designed to guide and distribute the ice sprayed onto the inner circumferential surface of the ice-making component 100 in a uniform manner.

[0071] The guide 310 is attached to the shaft 200 and rotates with the shaft. The guide 310 is positioned longitudinally along the shaft, and one end of the guide 310 is in contact with the inner wall of the ice-making component 100, allowing the guide 310 to rotate along with the rotation of the shaft 200, seemingly cleaning the inner wall.

[0072] The guide 310 must distribute the sprayed water uniformly, in contact with the inner wall of the ice-making component 100, after the water has been sprayed onto the inner wall of the ice-making component 100. In other words, the guide 310 is designed to operate in the opposite direction to the water spray direction (the direction of rotation of the shaft).

[0073] The end of the guide 310 can include a curved section 312 which is bent in the opposite direction to the rotating shaft 200 in order to allow the guide 310 to rotate smoothly in contact with the inner wall of the ice-making component 100.

[0074] Meanwhile, the cutting component 400 is attached to the shaft 200 and is designed to cut the ice produced on the inner wall of the ice-making component 100 during rotation.

[0075] The cutting component 400 can be located within the shaft, opposite the water spray component 300. The cutting component 400 can include cutting blades arranged at predefined intervals within the ice-making component 100; and a blade attachment area is provided to secure the cutting blades to the shaft.

[0076] The device for producing scraped ice according to the illustrated embodiment can further include a strength-reinforcing support element 210, which is rotatable in the ice-making component 110 and through which the shaft 200 passes (see Fig. 2).

[0077] The shaft 200 has one end that is cut off vertically with respect to its longitudinal direction, so that a cross-sectional area can have a circular shape from which one side has been cut away. Such a shaft 200 can pass through the reinforcing support element 210 and rotate together with the shaft 200 without being in free-running position relative to the shaft 200.

[0078] The reinforcement support element 210 can only be provided in the ice-making component 100, and the pipe 302 of the water spray component 300 can be attached to the reinforcement support element 210. Alternatively, the cutting component 400 or the guide 310 can be attached to the reinforcement support element 210. Accordingly, the reinforcement support element 210 can be provided as an independent element from the shaft 200, thus simplifying its assembly process and increasing the shaft's strength.

[0079] Meanwhile, the water sprayer 500 and the ice compartment 600 can be rotated while they are attached to the shaft 200.

[0080] Alternatively, as in Fig. 5 and Fig. As shown in Figure 6, the device for producing scraped ice can further include a hollow shaft 220 which is connected to a lower end of the shaft 200 and to both the ice compartment 600 and the water compartment 500 and which is designed to rotate together with the shaft 200.

[0081] An insertion area 222 is provided at the upper end of the hollow shaft 220 to ensure it is firmly inserted into the shaft. One end of the shaft is vertically cut off, and the cross-sectional area of ​​the shaft 200 is not a complete circle, so that the shaft 200, inserted into the insertion area 222, can transmit the rotational force to the hollow shaft 220 without idle.

[0082] The hollow shaft 220 can include an internal opening 202; and an opening-passage tube 224 is provided in the opening 202. The tube 302 can be provided in the opening 202 and pass through the opening-passage tube 224 to be attached to the shaft 222, which is inserted in the upper region of the hollow shaft 220 or the reinforcement support element 210. The water supplied via the tube 302 can be sprayed onto the inner wall of the ice-making component 100 through the through-opening 304.

[0083] The lower portion of the hollow shaft 220 is inserted into a rotating support element 705, which is designed as a cylinder with an open top. The rotating support element 705 can be configured to assist the rotation of the hollow shaft 220. The rotating support element 705 can include a water supply opening 705a, which is aligned with the opening 202 provided in the hollow shaft 220. Water is supplied to the pipe 302 from the outside via the water supply opening 705a.

[0084] The rotational mounting element 705 is provided in the base plate 704 and the water supply opening 705a is provided through the base plate 704, which is located in an interior area of ​​the rotational mounting element 705.

[0085] The rotation support element 705 can include the connector (not shown). One side of the connector (not shown) is connected to the pipe 302 and the other side of the connector (not shown) is connected to the water supply path (not shown) which is connected to the external water supply source, so that the pipe 302 cannot be twisted even when the hollow shaft 220 is rotated.

[0086] Fig. Figure 7 is a perspective view showing part of the device for producing the scraped ice. Fig. Figure 8 is a horizontal sectional view of Fig. 5 in the view from below.

[0087] With reference to Fig. 7 and Fig. Section 8 describes the structure designed to separate the unfrozen water and the shaved ice.

[0088] The water compartment 500 has an open top to store the unfrozen water that falls from the ice-making component 100, and a certain depth.

[0089] Meanwhile, the water compartment 500 can contain a drainage path 502 designed to drain the stored unfrozen water. The drainage path 502 can be connected to a bottom of the water compartment 500 to drain the unfrozen water to the outside. The drainage path 502 can be connected to the opening 202 provided in the hollow shaft 220 to exchange and supply the low temperature of the unfrozen water with the opening 202, thereby lowering the temperature of the water in the tube 302 through heat exchange with the water supplied via the tube 302. Accordingly, the amount of unfrozen water falling from the ice-making component 100 can be reduced, and unnecessary energy consumption can be saved.

[0090] Meanwhile, the ice compartment 600 can contain an ice accumulation area 602 to accumulate the scraped ice (SI) that falls from the ice-making component 100; and a rib 604 to prevent ice from falling is provided in the ice accumulation area 602 to prevent scraped ice from falling from the ice accumulation area 602.

[0091] The ice accumulation area 602 is provided at a lower point below the cutting component 400 as a surface projecting horizontally from the hollow shaft 220, so that the scraped ice cut from the inner wall of the ice-making component 100 by the cutting component 400 can accumulate in the ice accumulation area 602. The ice accumulation area 602 can be fan-shaped. A first central angle (θ1) of the ice accumulation area 602 can be within 180° to avoid contact with the unfrozen water falling from the ice-making component 100.

[0092] The rib 604 for preventing ice from falling projects upwards from an angle of the ice accumulation area 602. In other words, the rib 604 for preventing ice from falling can be a rib projecting upwards from a point at a radius spaced a certain distance from the center of the ice accumulation area 602, taking into account the polar coordinate system.

[0093] Meanwhile, the ice compartment 604 had two open sides corresponding to the radius of the ice accumulation area 602, except for the angle of the ice accumulation area 602. In other words, with respect to the polar coordinate system, the ice compartment 600 contains a first dispensing opening 606 and a second dispensing opening, which are open at an angle to discharge the scraped ice (SI) accumulated in the ice compartment 600.

[0094] However, the device for producing scraped ice according to the illustrated embodiment can further include an ice guide rib 900, which is designed to dispense the scraped ice (SI) that accumulates in the ice compartment 600.

[0095] The ice guide rib 900 is attached to a lower portion of the ice-making component 100 and is designed to move along the inside of the rotating ice chamber 600. Specifically, the ice falling after being cut in the cutting component 400 can accumulate on the top of the ice accumulation area 602 as the ice chamber 600 rotates with respect to the shaft. The ice guide rib 900 can move through the ice chamber 600 after passing through the first discharge opening 606, which is formed in an open side of the ice chamber 600, and then push the scraped ice (SI) to discharge it through the second discharge opening 608, where it falls outside the ice chamber 600.

[0096] Alternatively, the ice guide rib 900 can be attached to a lower area of ​​the housing 116 using an additional element. In other words, the ice guide rib 900 can be attached in any position that allows only relative movement with the rotating ice compartment 600.

[0097] The ice-guiding rib 900 can include a first rib 902, which is provided in a radial direction with respect to the shaft 200; and a second rib 904, which is provided vertically with respect to the first rib 902. The first rib 902 has a length corresponding to the radius of the ice accumulation area 602 in order to clear and traverse the entire upper surface of the ice accumulation area 602. The second rib 904 projects from the first rib 902 in a vertical direction to have a predefined length in order to prevent damage to the first rib 902, which can be caused by a large torque exerted on the first rib 902 by the scraped ice that accumulates only at the end of the first rib 902.

[0098] The water compartment 500 can be installed below the ice compartment 400 so as not to be located within the rotation radius of the ice guide rib 900.

[0099] Alternatively, the water compartment 500 can have a fan shape, and a second central angle (θ2) of the water compartment 500 can be smaller than the first central angle (θ1) of the ice compartment 600. This is because it is not necessary to store the unfrozen water in the water compartment 500, as the drainage path 502 is connected to the water compartment 500.

[0100] The device for producing scraped ice can further include an ice storage unit 910, which is provided below the ice guide rib 900.

[0101] The ice storage unit 910 has an open top and a predefined depth to store the scraped ice (SI) that falls from the ice compartment 600. The user can then use the scraped ice (SI) stored in the ice storage unit 910.

[0102] The ice storage unit 910 can be provided in a surface of the base plate 704 and be removable to increase ease of use for the user.

[0103] Fig. Figure 9 is a representation illustrating a state in which the sprayed water in the device for producing scraped ice turns into ice, and Fig. Figure 10 is a representation illustrating a state in which shaved ice is taken from an ice compartment into the device for producing shaved ice.

[0104] With reference to Fig. 9 and Fig. Section 10 describes the operation of the device for producing scraped ice.

[0105] With reference to Fig. 9a A signal requesting the production of shaved ice is entered by a user request or a predefined program, and the ice-making component 100 is cooled by the cooling circuit system. Thus, the shaft 200 rotates in one direction counterclockwise, and the water spray component 300 sprays water onto the inner wall of the ice-making component 100. As in Fig. As shown in Figure 9b, the sprayed water is distributed uniformly along the inner wall of the ice-making component 100 by the guide 310, and the cooled ice-making component 100 produces the ice (I). When the shaft 200 is rotated by 180°, the cutting component 400 cuts the ice (I) produced on the inner wall of the ice-making component 100 to produce scraped ice (SI). The scraped ice (SI) falls down and accumulates in the ice compartment 600.

[0106] The water spray component 300 and the cutting component 400 are positioned at a 180° angle, preventing water from being sprayed directly onto the inner wall of the ice-making component 100, from which the ice is cut by the cutting component 400. This allows time for the water to cool via the cooling circuit system before it is sprayed again by the opposite water spray component 300. Consequently, the risk of the water sprayed onto the ice-making component 100 freezing is minimized, thus preventing the formation of unfrozen water.

[0107] As in Fig. As shown in Figure 10a, the scraped ice (SI) cut off and falling from the cutting component 400 can accumulate in the ice compartment 600. As shown in Fig.As shown in Figure 10b, the ice compartment 600, which rotates counterclockwise together with the shaft 200 or the hollow shaft 220, can engage the stationary ice guide rib 900, and the ice guide rib 900 can traverse the interior of the ice compartment 600. The ice guide rib 900 can push the scraped ice (SI) out of the ice compartment 600 and discharge it to the outside. The discharged scraped ice (SI) can be stored in the ice reservoir 910 and used as needed.

[0108] Since the present features can be implemented in various forms without deviating from their properties, it is understood that the embodiments described above are not limited by any details of the preceding description, unless otherwise stated, but rather are to be considered as broad in scope according to the definition in the claims in the Annex, and therefore all changes and modifications that fall within the scope and extent of the claims or equivalents to such scope and delimitations are to be covered by the claims in the Annex.
