Description

Technical Field

[0001] This invention relates to a flowing water evaporator, an ice-making device and a water purification device including the same, wherein during de-icing, heat supplied by a high-temperature fluid is uniformly transferred to the ice, thus enabling easy separation of the ice without the use of separate de-icing water, thereby minimizing ice melting during de-icing, and preventing a decrease in the cleanliness of the de-icing water because the ice-making water circulates only to the outside of a pair of outer plate components. Background Technology

[0002] Typically, a flow-through evaporator is used to generate ice by flowing ice-making water over the evaporator surface, then removes the generated ice from the evaporator and supplies it to the user. This type of flow-through evaporator can be used in various devices that require ice generation, such as ice-making equipment or water purification systems.

[0003] Korean Patent Publication No. 10-1335953, issued by Daeyeong E&B Co., Ltd. of South Korea, discloses a conventional ice maker. This ice maker includes: an evaporator in which a low-temperature fluid flows; an ice-making tray vertically positioned to contact the evaporator; a water tank disposed below the ice-making tray for storing water (ice-making water and de-icing water) falling from the ice-making tray; and an ice storage compartment disposed outside the water tank for storing the falling ice. Furthermore, the ice-making tray is provided with a separating part for laterally separating the ice to generate multiple ice crystals. When water flows through this ice-making tray, ice is generated at the portion in contact with the evaporator; specifically, the generated ice is formed not only adhering to the ice-making tray but also to the separating part. Therefore, to de-ice, all parts attached to the ice need to be separated quickly. To separate the portion attached to the ice-making tray, a high-temperature fluid is supplied to the evaporator. To separate the portion attached to the separating partition, de-icing water flows through the inside of the partition, i.e., the part where the evaporator is located. Without de-icing water, the portion attached to the separating partition cannot be separated quickly, and due to the high-temperature fluid supplied to the evaporator, the ice size becomes very small, potentially leading to reduced user satisfaction. Therefore, de-icing water is the only option. However, since this de-icing water is collected in a water tank after passing through the copper-tubed outer surface of the evaporator and circulates with the ice-making water, the cleanliness of the generated ice decreases.

[0004] The ice-making unit disclosed in Japanese Patent Publication No. 2009-264729 of Hoshizaki Electric Co., Ltd. includes: an ice-making tray with a plurality of protrusions extending longitudinally and arranged laterally at each predetermined interval; and an evaporation tube disposed on the back of the ice-making tray and extending laterally. When ice-making water flows in the ice-making tray, ice is generated at the part in contact with the evaporation tube, and the ice generated in the manner described above adheres to and forms on the ice-making tray and the protrusions. When the de-icing operation for separating ice is started, a high-temperature fluid valve is opened to circulate high-temperature fluid to the evaporation tube, and a water supply valve is also opened to supply de-icing water to the back of the ice-making tray, so that the ice-making tray is heated and ice is separated. Even in this case, since the de-icing water is collected in a water tank after passing through the outer side of the evaporator made of copper tube material and circulates with the ice-making water, there is still a problem of decreased cleanliness of the generated ice.

During de-icing, the heat supplied by the high-temperature fluid is uniformly transferred to the ice, thus enabling easy separation of the ice without the use of separate de-icing water, thereby minimizing the melting of the ice during de-icing. Furthermore, since the ice-making water circulates only to the outside of a pair of plate components, the cleanliness of the ice-making water is improved.

That is, the aforementioned high-temperature fluid supply port 421 may include a first high-temperature fluid supply port 421a formed on one outer side plate component 100 and a second high-temperature fluid supply port 421b formed on another outer side plate component 100, and the high-temperature fluid discharge port 422 may include a first high-temperature fluid discharge port 422a formed on one outer side plate component 100 and a second high-temperature fluid discharge port 422b formed on another outer side plate component 100.

[0083] like Figure 4 As shown, the first surface C1 of the generated ice C is attached to the ice-generating surface 110, and the second surface C2 extending from the first surface C1 is attached to the outer surface of the partition 111. That is, when the ice-making water W1 flows, ice C is first generated on the ice-generating surface 110, and in this case, the first surface C1 of the ice C is attached to the ice-generating surface 110. In this state, as the ice-making water W1 continues to flow, the size of the ice C increases, and therefore ice also forms on the outer surface of the partition 111. In this case, the second surface C2 of the ice C is attached to the outer surface of the partition 111. Therefore, in order to de-ice, it is necessary to quickly separate the first surface C1 and the second surface C2 of this ice C. For this purpose, a high-temperature fluid, such as..., can be supplied to the interior of the flow path plate component 200. Figure 5 As shown, heat supplied by the high-temperature fluid flowing through the flow path plate component 200 is transferred to ice C through the heat transfer surface 120 and the ice-forming surface 110, causing the first surface C1 to separate from the ice-forming surface 110. Simultaneously, the high-temperature fluid supplied through the supply tank 112a moves to the interior of the partition 111 through the second flow path 112, and heat is transferred to the partition 111 through the high-temperature fluid flowing inside the partition 111, allowing the second surface C2 to separate from the partition 111. That is, during de-icing, heat supplied by the high-temperature fluid flowing through the flow path plate component 200 and the high-temperature fluid flowing inside the partition 111 of the outer plate component 100 is uniformly transferred to ice C, thus allowing easy separation of ice C without the use of separate de-icing water, thereby minimizing the degree of melting of ice C during de-icing. Furthermore, since the ice-making water W1 circulates only towards the outside of the pair of outer plate components 100, the cleanliness of the circulating ice-making water W1 and ice C can be effectively prevented from decreasing.

[0084] like Figure 5 As shown, the water-flow evaporator of this embodiment may further include an inner side plate component 300 joined to the heat transfer surface 120 to prevent the aforementioned fluid flowing inside the supply channel 112a and the partition 111 from leaking into the space between a pair of outer side plate components 100. To join the inner side plate component 300 to the heat transfer surface 120 as described above, a covering material may be disposed between the outer side plate component 100 and the inner side plate component 300. In this case, the covering material may be sprayed to form a covering layer, or a covering sheet may be used as the covering material. With the covering material disposed between the outer side plate component 100 and the inner side plate component 300, they can be joined together by a brazing process, thereby sealing the supply channel 112a and the partition 111, preventing high-temperature fluid from leaking into the inner side of the pair of outer side plate components 100, thus ensuring structural stability. In this case, curved ribs 330 extending inward along the depth direction Y may be formed around the pair of inner side plate components 300 arranged facing each other. When the curved rib 330 is formed in the manner described above, the spacing between the pair of inner side plate components 300 is stably maintained, so that they can be stably joined with the heat transfer surface 120 of the outer side plate component 100 during the brazing process, and the flow path plate component 200 can be easily ensured to be located in the space between the pair of inner side plate components 300.

[0085] like Figure 3 As shown, in the flowing evaporator of this embodiment of the invention, the baffles 111 extend parallel to the direction of the flow of ice-making water W1, and multiple baffles 111 are arranged at predetermined intervals. The outer plate component 100 may further include: a connecting groove 112b for connecting adjacent baffles 111; and a discharge groove 112c for discharging the fluid flowing inside the baffles 111. That is, because the connecting groove 112b is formed, the baffles 111 are connected, so even if high-temperature fluid is supplied to one baffle 111, high-temperature fluid can be supplied to multiple baffles 111, thereby simplifying the overall structure of the flowing evaporator. During the flow of ice-making water W1 between adjacent baffles 111, ice C is generated at each position of the low-temperature fluid flow, so that multiple ices can be produced simultaneously, thereby improving user convenience.

[0086] In this case, in the flow-through evaporator of this embodiment of the invention, the supply tank 112a communicates with at least one of the plurality of partitions 111 and supplies high-temperature fluid to the interior of the partition 111. The high-temperature fluid supplied to the partition 111 can move through the aforementioned connecting tank 112b to another partition 111 adjacent to the partition 111 and then be discharged through the discharge tank 112c. That is, when supplying high-temperature fluid to the plurality of partitions 111, the second flow paths 112 can be connected in series so that the high-temperature fluid moves the plurality of partitions 111 sequentially, or the second flow paths 112 can be connected in parallel so that the high-temperature fluid moves the plurality of partitions 111 simultaneously. When the connecting tank 112b is formed in the manner described above, the partitions 111 are connected, so even if high-temperature fluid is supplied to one partition 111, high-temperature fluid can be supplied to the plurality of partitions 111, thereby simplifying the structure and improving productivity.

[0087] Figure 6 This is a perspective view showing the assembled state of a pair of flow path board components according to an embodiment of the present invention. Figure 7 To illustrate a perspective view of a flow path board component according to an embodiment of the present invention, Figure 8 A perspective view of another flow path board component according to an embodiment of the present invention is provided.

[0088] like Figures 6 to 8 As shown, in the flowing evaporator of this embodiment of the invention, a pair of flow path plate components 200 are arranged facing each other, and each flow path plate component 200 may include a main channel 210 protruding outward. Through this main channel 210, a low-temperature fluid flows during ice making and a high-temperature fluid flows during de-icing. Since the main channel 210 is formed in the pair of flow path plate components 200, the structural stability of the main channel 210 is improved, and the position of the flow path plate component 200 inside the outer plate component 100 can be stably fixed. The main channel 210 includes a heat transfer channel 211 extending along the width direction X and exchanging heat with the heat transfer surface 120. In this case, more than one such heat transfer channel 211 may be arranged along the height direction Z, thereby generating ice C at multiple locations along the height direction Z. Furthermore, the main channel 210 may also include a connecting channel 212 for connecting such heat transfer channels 211.

[0089] In the flow-through evaporator of this embodiment, the flow path plate component 200 may include a first opening 220, which is formed through the flow path, allowing the fluid flowing through the main channel 210 to directly contact the heat transfer surface 120. That is, the low-temperature or high-temperature fluid flowing along the main channel 210 transfers heat during the process of directly contacting the heat transfer surface 120 through the first opening 220, thereby not only improving ice-making performance but also facilitating ice separation during de-icing and maintaining the size or shape of the ice C, thus improving user satisfaction.

[0090] In this case, as described above, since the inner side plate component 300 is disposed in conjunction with the heat transfer surface 120 formed on the outer side plate component 100, even if the first opening 220 is formed in the main groove 210, the low temperature fluid or high temperature fluid cannot directly contact the heat transfer surface 120 due to the inner side plate component 300. At this time, the inner side plate component 300 acts as a thermal barrier, which may cause the ice-making or de-icing performance to decrease. In order to prevent this situation, in the water flow evaporator of the present invention, the inner side plate component 300 may include a second opening 310, which is formed through the first opening 220 so that the fluid passing through the first opening 220 can directly contact the heat transfer surface 120. That is, an inner side plate component 300 is configured on the heat transfer surface 120 to prevent the high-temperature fluid flowing inside the partition 111 from leaking to the inside of a pair of outer side plate components 100. At the same time, the low-temperature fluid or high-temperature fluid passing through the first opening 220 passes through the second opening 310 in sequence and directly contacts the heat transfer surface 120. This not only improves the ice-making performance, but also makes it easier to separate ice during de-icing, thus improving user satisfaction.

[0091] like Figure 6 As shown, in the flow-through evaporator of this embodiment, the flow path plate component 200 includes a heat transfer column 230 that protrudes outward along the main channel 210 and contacts the heat transfer surface 120. In this case, the first opening 220 can be provided at the front end of the heat transfer column 230. As described above, since the heat transfer column 230 is in surface contact with the heat transfer surface 120, the heat transfer performance is improved, and the ice-making performance is improved when the low-temperature fluid flows. Furthermore, when the high-temperature fluid flows, the ice C can be easily separated. Moreover, the surface contact between the heat transfer column 230 and the heat transfer surface 120 can improve structural stability. In addition, the first opening 220 is formed at the front end of this heat transfer column 230, allowing the low-temperature fluid or the high-temperature fluid to directly contact the heat transfer surface 120, thereby improving the ice-making performance and increasing user satisfaction through rapid ice separation.

[0092] Figure 9 This is a perspective view showing the assembled state of the inner side plate component and the flow path plate component according to an embodiment of the present invention. Figure 10 for Figure 9 An enlarged view of part B.

[0093] like Figure 9 and Figure 10 As shown, the front end of the heat transfer column 230 is inserted into the second opening 310 formed in the inner side plate component 300. In this case, as Figure 5As shown, in the flow-through evaporator of this embodiment of the invention, a support surface 311 can be provided around the second opening 310 to support the outer side of the heat transfer column 230 when it is inserted. That is, since the heat transfer column 230 is inserted into the second opening 310, the low-temperature fluid or high-temperature fluid flowing in the main tank 210 can exchange heat with the heat transfer surface 120 while maintaining stable contact. Since the outer side of the heat transfer column 230 is supported by the support surface 311 formed in the second opening 310, the flow path plate component 200 and the inner side plate component 300 can be assembled in accurate positions during assembly, and after assembly, the assembly state of these components is stably maintained, thus ensuring structural stability even after long-term use.

[0094] like Figure 5 As shown, in the flow-through evaporator of this embodiment of the invention, a supply groove 112a is provided on each of a pair of outer side plate components 100, and the inner side plate component 300 can be configured to be joined to the pair of outer side plate components 100 respectively. Figure 4 As shown, in addition to the supply tank 112a, the outer side plate component 100 may also have a connecting tank 112b and a discharge tank 112c, and may be provided with a high-temperature fluid supply port 421 communicating with each supply tank 112a and a high-temperature fluid discharge port 422 communicating with each discharge tank 112c. As described above, with the supply tanks 112a respectively formed on a pair of outer side plate components 100, when the inner side plate components 300 are respectively engaged and independently supplied with high-temperature fluid, the ice C formed on the ice-generating surfaces 110 of the pair of outer side plate components 100 will quickly separate, thereby improving user satisfaction.

[0095] like Figure 5 As shown, in the flow-through evaporator of this embodiment of the invention, one of the pair of flow path plate components 200 may include a connecting piece 240 that engages with the other flow path plate component 200. As an example, this connecting piece 240 can be bent to surround a portion of the other flow path plate component 200, but is not necessarily limited to this shape; it can be any shape capable of preventing relative movement of the pair of flow path plate components 200. As described above, structural stability can be ensured when the pair of flow path plate components 200 are engaged with each other via the connecting piece 240.

[0096] On the other hand, such as Figure 5As shown, in the flow-through evaporator of this embodiment, one of the pair of flow path plate components 200 may include a support plate 250 that contacts and is supported by the inner side plate component 300. This support plate 250 may extend for a predetermined length along the width direction X or the height direction Z, and is in contact with the surface of the inner side plate component 300 while extending a predetermined distance outward toward the inner side plate component 300 in the depth direction Y. Furthermore, in the flow-through evaporator of this embodiment, the inner side plate component 300 may include a corresponding plate 320 that contacts and is supported by the support plate 250. This corresponding plate 320 may extend for a predetermined length along the width direction X or the height direction Z, and is in contact with the surface of the support plate 250 while extending a predetermined distance inward toward the inner side of the flow path plate component 200 in the depth direction Y. As described above, when the support piece 250 and the corresponding piece 320 are formed by extending at a predetermined distance along the depth direction Y, it is easy to ensure that the flow path plate component 200 can be disposed in the space between the inner side plate components 300. Since the support piece 250 and the corresponding piece 320 are in contact with each other and are supported, the assembly state between the flow path plate component 200 and the inner side plate component 300 is stably maintained, and thus structural stability can be ensured even after long-term use.

[0097] like Figure 5 As shown, in the flow-through evaporator of this embodiment of the invention, mating surfaces 130 capable of engaging with each other can be respectively provided around a pair of outer side plate components 100. As described above, when the mating surfaces 130 are respectively provided around a pair of outer side plate components 100, not only are these components stably engaged with each other, but the interior of the pair of outer side plate components 100 is also sealed, so that air or ice-making water W1 will not flow in, thereby preventing a decrease in the cleanliness of the ice-making water W1.

[0098] In this case, such as Figure 5 As shown, in the flow-through evaporator of this embodiment of the invention, curved surfaces 140 that bend inward are respectively provided around a pair of outer side plate members 100 arranged facing each other, and a mating surface 130 can be provided at the front end of the curved surface 140. That is, by forming curved surfaces 140 on a pair of outer side plate members 100 respectively, the internal space of the configurable flow path plate member 200 can be easily ensured, thereby improving manufacturability.

[0099] As described above, this type of flow-through evaporator 20 for an ice-making apparatus includes: a pair of outer plate members 100 arranged facing each other; and a flow path plate member 200 disposed between the pair of outer plate members 100 for separating the space between the pair of outer plate members 100 to form a first flow path 201 for the flow of a low-temperature fluid for generating ice C or a high-temperature fluid for separating the generated ice. The outer plate members 100 may include: a heat transfer surface 120 formed on the inner side for thermal contact with the fluid; an ice generating surface 110 formed on the outer side such that a first surface C1 of ice C is attached; a partition 111 separating the ice generating surface 110 and protruding outward to attach a second surface C2 formed on the first surface C1 of ice C, extending in a direction intersecting the flow direction of the fluid flowing in the first flow path 201; and a supply channel 112a protruding outward to form a second flow path 112 communicating with the interior of the partition 111 to supply high-temperature fluid to the interior of the partition 111. That is, in order to de-ice, it is necessary to quickly separate the first surface C1 and the second surface C2 of this ice C. For this purpose, a high-temperature fluid, such as..., can be supplied to the interior of the flow path plate component 200. Figure 5 As shown, heat supplied by the high-temperature fluid flowing through the flow path plate component 200 is transferred to ice C through the heat transfer surface 120 and the ice-forming surface 110, causing the first surface C1 to separate from the ice-forming surface 110. Simultaneously, the high-temperature fluid supplied through the supply tank 112a moves to the interior of the partition 111 through the second flow path 112, and heat is transferred to the partition 111 through the high-temperature fluid flowing inside the partition 111, allowing the second surface C2 to separate from the partition 111. That is, during de-icing, heat supplied by the high-temperature fluid flowing through the flow path plate component 200 and the high-temperature fluid flowing inside the partition 111 of the outer plate component 100 is uniformly transferred to ice C, thus allowing easy separation of ice C without the use of separate de-icing water, thereby minimizing the degree of melting of ice C during de-icing. Furthermore, since the ice-making water W1 circulates only towards the outside of the pair of outer plate components 100, the cleanliness of the circulating ice-making water W1 and ice C can be effectively prevented from decreasing.

[0100] On the other hand, as described above, the flow-type evaporator 20 for the water purification device also includes: a pair of outer plate members 100, arranged facing each other; and a flow path plate member 200, disposed between the pair of outer plate members 100, for separating the space between the pair of outer plate members 100 to form a first flow path 201 for the flow of a low-temperature fluid for generating ice C or a high-temperature fluid for separating the generated ice. The outer plate members 100 may include: a heat transfer surface 120, formed on the inner side for thermal contact with the fluid; an ice generating surface 110, formed on the outer side, such that a first surface C1 of ice C is attached; a partition 111, separating the ice generating surface 110 and protruding outward to attach a second surface C2 formed on the first surface C1 of ice C, extending along a direction intersecting the flow direction of the fluid flowing in the first flow path 201; and a supply channel 112a, protruding outward to form a second flow path 112 communicating with the interior of the partition 111 to supply high-temperature fluid to the interior of the partition 111. That is, in order to de-ice, it is necessary to quickly separate the first surface C1 and the second surface C2 of this ice C. For this purpose, a high-temperature fluid, such as..., can be supplied to the interior of the flow path plate component 200. Figure 5 As shown, heat supplied by the high-temperature fluid flowing through the flow path plate component 200 is transferred to ice C through the heat transfer surface 120 and the ice-forming surface 110, causing the first surface C1 to separate from the ice-forming surface 110. Simultaneously, the high-temperature fluid supplied through the supply tank 112a moves to the interior of the partition 111 through the second flow path 112, and heat is transferred to the partition 111 through the high-temperature fluid flowing inside the partition 111, allowing the second surface C2 to separate from the partition 111. That is, during de-icing, heat supplied by the high-temperature fluid flowing through the flow path plate component 200 and the high-temperature fluid flowing inside the partition 111 of the outer plate component 100 is uniformly transferred to ice C, thus allowing easy separation of ice C without the use of separate de-icing water, thereby minimizing the degree of melting of ice C during de-icing. Furthermore, since the ice-making water W1 circulates only towards the outside of the pair of outer plate components 100, the cleanliness of the circulating ice-making water W1 and ice C can be effectively prevented from decreasing.

[0101] As described above, in the flowing water evaporator, ice-making device, and water purification device of the present invention, during de-icing, the heat supplied by the high-temperature fluid is uniformly transferred to the ice C, thus making it easy to separate the ice without using separate de-icing water, thereby minimizing the melting of the ice during de-icing. Furthermore, since the ice-making water W1 circulates only to the outside of a pair of outer plate members 100, the cleanliness of the ice-making water W1 can be effectively prevented from decreasing.

[0102] The embodiments of the present invention have been described above. However, the concept of the present invention is not limited to the embodiments presented in this specification. Those skilled in the art who understand the concept of the present invention can easily propose other embodiments by adding, changing, deleting, or adding structural elements within the same conceptual scope, but these will also fall within the conceptual scope of the present invention.
