Description

cold water tank assembly

[0001] The present invention relates to a cold water tank assembly.

[0002]

[0003] A water purifier is a general term for any device capable of receiving raw water, processing it to a state desired by the user, and then providing it to the user. Water purifiers can filter raw water using various types of filters before supplying it to the user.

[0004] Recently, water purifiers have been developed and are in use that not only filter raw water to provide purified water but also supply hot water, cold water, and ice to users.

[0005] A water purifier designed to dispense cold water is equipped with a cold water tank for holding cold water and a cooling unit for cooling the cold water contained in the tank. Unlike water purifiers equipped with a direct-flow cooling function, water purifiers equipped with a cooling tank have the advantage of being able to dispense a large volume of cold water at once.

[0006] However, conventional cold water tanks had the disadvantage of being unable to uniformly cool all the water contained within and preferentially cooling the water located adjacent to the cooling section, making it difficult to utilize the entire amount of water stored in the tank as cold water. In other words, there was a disadvantage in that only a smaller amount of cold water than the actual capacity of the cold water tank could be used.

[0007] In particular, in the case of conventional direct-flow storage type cold water tanks, the extraction rate of cold water below 10°C relative to the tank capacity is less than 70%, and due to this problem with cold water generation efficiency, there was a problem of the size becoming larger. In other words, there is a limitation in that the tank capacity must be made larger to satisfy the amount of cold water extraction required by the user.

[0008] Furthermore, in the case of conventional reservoir-type chilled water tanks, the wide surface area of ​​the flow paths formed inside the tank leads to a problem where the chilled water temperature varies at different locations due to the distance from the heat exchange components. When the chilled water temperature differs depending on the location within the tank, a mixing phenomenon occurs, resulting in reduced chilled water cooling efficiency and, furthermore, the disadvantage of making First-In, First-Out (FIFO) operation difficult. In addition, stagnant air remains inside the chilled water tank in some sections of the flow paths, causing a decrease in cooling efficiency, and there is the issue that additional components must be introduced to expel the residual air from the tank to the outside.

[0013] According to the present invention, the objective is to provide a cold water tank assembly in which the cold water generation efficiency relative to the volume of the cold water tank is significantly improved compared to a conventional cold water tank.

[0015] In addition, the purpose is to provide a cold water tank assembly in which multiple cold water channels with small cross-sectional areas are formed inside the cold water tank assembly to reduce the temperature variation of the cold water, thereby enabling the generation and provision of cold water at a constant temperature to the user.

[0016] In addition, the purpose is to provide a cold water tank assembly in which the cross-section of the cold water flow path formed inside the cold water tank assembly is circular so that no air remains inside the cold water flow path, thereby solving the problem of air remaining in the corners of conventional cold water tank assemblies where the cross-section is polygonal, which required an air discharge structure.

[0079] In some cases, to avoid obscuring the concept of the present invention, known structures and devices may be omitted or illustrated in the form of a block diagram focusing on the core functions of each structure and device.

[0080] Throughout the specification, when a part is described as "comprising" or "including" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, terms such as "...part," "...unit," and "module" as used in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software. Additionally, "one (a or an)," "one," "the," and similar related terms may be used in the context describing the invention (particularly in the context of the following claims) to include both singular and plural forms, unless otherwise indicated in the specification or clearly contradicted by the context.

[0081] In describing the embodiments of the present invention, specific descriptions of known functions or configurations will be omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention. Furthermore, the terms described below are defined in consideration of their functions in the embodiments of the present invention, and these definitions may vary depending on the intentions or practices of the user or operator. Therefore, such definitions should be based on the content throughout this specification.

[0082]

[0083] The present invention will be described in detail below with reference to the attached drawings.

[0084]

[0085] Referring to FIG. 1, a cold water tank assembly (1) according to an embodiment of the present invention includes a cover (100) and a case (200).

[0086]

[0087] The cover (100) and the case (200) can each be formed from a synthetic resin material, thereby reducing the weight and manufacturing cost of the entire cold water tank assembly (1) and improving manufacturing convenience.

[0088]

[0089] In one embodiment of the present invention, a first fluid transfer pipe (110) is formed in the cover (100), and a second fluid transfer pipe (210) is formed in the case (200). In another embodiment of the present invention, both the first fluid transfer pipe (110) and the second fluid transfer pipe (210) may be formed in the cover (100) (see FIG. 7), and both the first fluid transfer pipe (110) and the second fluid transfer pipe (210) may be formed in the case (200).

[0090] When the cover (100) and the case (200) are combined, a cold water channel (f) is formed inside, and the first fluid transfer pipe (110) is connected to one end of the cold water channel (f), and the second fluid transfer pipe (210) is connected to the other end of the cold water channel (f). Accordingly, fluid introduced through the second fluid transfer pipe (210) passes through the cold water channel (f), and fluid that has passed through the cold water channel (f) can be discharged to the outside through the first fluid transfer pipe (110). In other words, the first fluid transfer pipe (110) may be an outlet pipe, and the second fluid transfer pipe (210) may be an inlet pipe. However, in another embodiment of the present invention, the first fluid transfer pipe (110) may be an inlet pipe and the first fluid transfer pipe (210) may be an outlet pipe.

[0091]

[0092] Meanwhile, the cover (100) may have an open lower side and the case (200) may have an open upper side (see FIG. 3 and 4). That is, the cover (100) can be inserted into the case (200) through the open upper side of the case (200). In other words, the case (200) can be inserted into the cover (100) through the open lower side of the cover (100).

[0093]

[0094] Referring to FIG. 3, the cover (100) includes one or more first partitions (120; 120a, 120b). The one or more first partitions (120; 120a, 120b) are structures extending downward from the upper surface of the cover (100), and the one or more first partitions (120a, 120b) may be spaced apart from each other at a predetermined interval along a radial direction.

[0095] Referring to FIG. 4, the case (200) includes one or more second partitions (220; 220a, 220b). The one or more second partitions (220; 220a, 220b) are structures extending upward from the bottom surface of the case (200), and the one or more second partitions (220a, 220b) may be spaced apart from each other at a predetermined interval along a radial direction.

[0096] In a combined state of the cover (100) and the case (200), at least one first partition (120) may be positioned between a plurality of second partitions (220a, 220b), and a cold water channel (f) may be formed in the space between the first partition (120) and the second partition (220).

[0097]

[0098] A first screw thread may be formed on the first bulkhead (120), and a second screw thread may be formed on the second bulkhead (220). The first screw thread of the first bulkhead (120) and the second screw thread of the second bulkhead (220) may be screw-coupled to each other, and a cold water channel (f) may be formed between the first screw thread and the second screw thread. Below, a structure for forming the cold water channel (f) will be described in more detail.

[0099]

[0100] A first screw thread projection (121) protruding radially outward is formed on the outer surface of the first bulkhead (120), and a first screw thread groove (122) recessed radially outward is formed on the inner surface of the first bulkhead (120).

[0101] On the outer surface of the second partition (220), a second screw thread projection (221) is formed that protrudes radially outward and is coupled to the first screw thread groove (122), and on the inner surface of the second partition (220), a second screw thread groove (222) is formed that is recessed radially outward and is coupled to the first screw thread projection (121).

[0102]

[0103] The first screw thread projection (121) and the second screw thread projection (221) may be structures that protrude continuously along the screw thread direction, and the first screw thread groove (122) and the second screw thread groove (222) may be structures that are recessed continuously along the screw thread direction. Accordingly, the cover (100) and the case (200) can be connected to each other by rotating relative to each other along the screw thread direction, and during the process of relative rotation, the first screw thread projection (121) is connected to the second screw thread groove (222), and the second screw thread projection (221) is connected to the first screw thread groove (122). As a result, the cold water tank assembly (1) can be manufactured using the screw thread connection method of the cover (100) and the case (200), and the ease of manufacturing can be improved.

[0104]

[0105] On the outer surface of the first partition (120), a first partial cold water channel (123) is formed by being recessed radially inward between a first screw thread projection (121) located on the upper side and a first screw thread projection (121) located on the lower side, and on the inner surface of the first partition (120), a second partial cold water channel (124) is formed by being recessed radially outward between a first screw thread groove (122) located on the upper side and a first screw thread groove (122) located on the lower side (see FIG. 3).

[0106] Additionally, on the outer surface of the second partition (220), a third partial cold water channel (223) is formed by being recessed radially outward between the second threaded projection (221) located on the upper side and the second threaded projection (221) located on the lower side, and on the inner surface of the second partition (220), a fourth partial cold water channel (224) is formed by being recessed radially outward between the second threaded groove (222) located on the upper side and the second threaded groove (222) located on the lower side (see FIG. 4).

[0107] The cross-sections of the first to fourth portions of cold water channels (123, 124, 223, 224) may be semicircular, and when the cover (100) and the case (200) are combined, the first portion of the cold water channel (123) may face the fourth portion of the cold water channel (224), and the second portion of the cold water channel (124) may face the third portion of the cold water channel (223). That is, the first portion of the cold water channel (123) and the fourth portion of the cold water channel (224) may be combined to form a first cold water channel (f1) with a circular cross-section, and the second portion of the cold water channel (124) and the third portion of the cold water channel (223) may be combined to form a second cold water channel (f2) with a circular cross-section.

[0108] The first cold water channel (f1) and the second cold water channel (f2) may be alternately arranged along the radial direction and may each have a structure extending along a screw thread. In the cold water channels (f; f1, f2) formed within the cold water tank assembly (1) according to an embodiment of the present invention, a plurality of cold water channels (f1, f2) are formed within a single cold water tank assembly (1), thereby securing a channel area with a large surface area relative to the volume of the cold water tank assembly (1). That is, it is possible to provide a large amount of cold water to the user even with a relatively small cold water tank assembly (1).

[0109] In addition, each of the cold water channels (f1, f2) has a smaller cross-sectional area compared to conventional cold water tanks, which form only one cooling channel, thereby minimizing water mixing. As a result, the efficiency of cold water generation can be improved.

[0110] Furthermore, the cold water channels (f1, f2) may have a constant diameter along their length direction (thread direction) and a circular cross-section. This resolves the problem of reduced cold water generation efficiency caused by air stagnation at the corners of channels with a square cross-section in conventional cold water tanks. Consequently, the inconvenience of having to separately form an air vent to discharge stagnant air to prevent reduced cold water generation efficiency in conventional cold water tanks is avoided.

[0111]

[0112] In another embodiment of the present invention, a first threaded projection (121) protruding radially inwardly is formed on the inner surface of the first partition (120), and a first threaded groove (122) recessed radially inwardly is formed on the outer surface of the first partition (120). Additionally, a second threaded projection (221) protruding radially inwardly and coupled to the first threaded groove (122) is formed on the inner surface of the second partition (220), and a second threaded groove (222) recessed radially inwardly and coupled to the first threaded projection (121) is formed on the outer surface of the second partition (220). In other words, the formation positions of the threaded projection and the threaded groove may be opposite to those of the embodiment illustrated in FIGS. 3 and 4.

[0113] In the case of the corresponding embodiment, a first partial cold water channel (123) is formed on the inner surface of the first partition (120) and is recessed radially outward between the first threaded projection (121) located on the upper side and the first threaded projection (121) located on the lower side, and a second partial cold water channel (124) is formed on the outer surface of the first partition (120) and is recessed radially inward between the first threaded groove (122) located on the upper side and the first threaded groove (122) located on the lower side.

[0114] Additionally, on the inner surface of the second partition (220), a third portion cold water channel (123) is formed by being recessed radially outward between the second screw thread projection (221) located on the upper side and the second screw thread projection (221) located on the lower side, and on the outer surface of the second partition (220), a fourth portion cold water channel (224) is formed by being recessed radially inward between the second screw thread groove (222) located on the upper side and the second screw thread groove (222) located on the lower side.

[0115] The only difference is that the position of the threaded projection and the threaded groove is opposite to that shown in FIG. 3 and 5, but the cover (100) and the case (200) are connected in the direction of the threads to each other, and a plurality of cold water channels (f1, f2) are formed between the first partition (120) and the second partition (120).

[0116]

[0117] In both embodiments, the outer surface of the outermost second bulkhead (220) of the case (200) may be composed of a flat surface in which the second threaded projection (221) or the second threaded groove (222) is not formed. The outer surface of the outermost second bulkhead (220) of the case (200) forms one exterior of the cold water tank assembly (1) as shown in FIG. 1.

[0118]

[0119] One end of a plurality of cold water channels (f) formed by the mutual connection of the cover (100) and the case (200) is connected to the first fluid transfer pipe (110), and the other end of the cold water channels (f) is connected to the second fluid transfer pipe (210).

[0120] To achieve this, each end of a plurality of cold water channels (f) must be connected to one another and also connected to the first fluid transfer pipe (110) and the second fluid transfer pipe (210).

[0121] To maintain the airtightness of each cold water channel (f), the height at which the threaded projections (121, 221) protrude from the bulkhead and the depth at which the threaded grooves (122, 222) are recessed from the bulkhead may be equal. If the threaded projections and threaded grooves located at the top and bottom of each bulkhead are joined together without gaps, one end and the other end of the cold water channel cannot be connected to the fluid transfer pipe.

[0122] In order to connect one end of each cooling channel to the second fluid transfer pipe (210), the cold water tank assembly (1) according to an embodiment of the present invention may be formed such that the height (h2) of the first threaded projection (121) located at the bottom of the first partition (120) is lower than the height (h1) of the first threaded projection (121) located above it (see enlarged view of the bottom left of FIG. 7). In other words, the height (h2) of the first threaded projection (121) located at the bottom of the first partition (120) is configured to be lower than the depth of the recess of the second threaded groove (222) that is coupled to the first threaded projection (121), so that even if the bottom first threaded projection (121) is coupled to the second threaded groove (222), a gap is formed between the two components. The above empty space may be connected to the second fluid transfer pipe (210), so that fluid may flow into the cold water flow path (f) through the second fluid transfer pipe (210), and in another embodiment, fluid may be discharged to the second fluid transfer pipe (210) through the cold water flow path (f).

[0123] In another embodiment of the present invention, the width (w2) of the first threaded groove (122) located at the bottom of the first partition (120) may be formed wider than the width (w1) of the first threaded groove (122) located above it (see the enlarged view of the bottom right of FIG. 7). The width (w2) of the first threaded groove (122) located at the bottom of the first partition (120) may be formed wider than the width of the second threaded projection (221) coupled to the first threaded groove (122), and even if the bottom second threaded projection (221) is coupled to the bottom first threaded groove (122), a gap is formed between the two components. The above empty space may be connected to the second fluid transfer pipe (120), so that fluid may flow into the cold water path (f) through the second fluid transfer pipe (120), and in another embodiment, fluid may be discharged to the second fluid transfer pipe (210) through the cold water path (f).

[0124] In another embodiment, when the cover (100) and the case (200) are fully combined, the bottom end of the first partition (120) may be spaced apart from the bottom surface (201) of the case (200) at a certain distance. As a result, an empty space communicating with the second fluid transfer pipe (210) may be formed between the bottom end of the first partition (120) and the bottom surface (201) of the case (200).

[0125]

[0126] Additionally, in order to connect the other end of each cold water channel to the first fluid transfer pipe (110), when the cover (100) and the case (200) are fully combined, the upper end of the second partition (220) along at least some of the screw thread direction may be spaced apart from the bottom surface (101) of the cover (100) at a certain distance (see upper left enlarged view of FIG. 7). As a result, a void space is formed between the upper end of the second partition (220) and the bottom surface (101) of the cover (100), and the void space may be connected to the first fluid transfer pipe (110), so that fluid passing through the cold water channel (f) can be discharged to the outside through the first fluid transfer pipe (110), and in another embodiment, fluid may also be introduced into the cold water channel (f) through the first fluid transfer pipe (110).

[0127] Meanwhile, the uppermost part of the second bulkhead (220) along the other thread direction may include a flat surface (220c) where the second thread groove (222) is not formed (see the upper right enlarged view of FIG. 7). As a result, a void space is formed between the bottom surface of the cover (100) and the first bulkhead (120), and the void space may be connected to the first fluid transfer pipe (110), so that fluid passing through the cold water path (f) can be discharged to the outside through the first fluid transfer pipe (110), and in another embodiment, fluid may also be introduced into the cold water path (f) through the first fluid transfer pipe (110).

[0128]

[0129]

[0130] Referring to FIG. 5, a third cold water channel (f3) in the shape of a cylinder, rather than a threaded cold water channel, may be formed in the center of the cold water tank assembly (1). To this end, the inner surface of the innermost second partition (220) of the case (200) may be composed of a flat surface in which the second threaded projection (221) or the second threaded groove (222) is not formed.

[0131] The cylindrical third cold water channel (f3) can also be connected to the first fluid transfer pipe (110) at one end and to the second fluid transfer pipe (210) at the other end.

[0132]

[0133] A temperature sensor (S) may be installed in the third cold water channel (f3). To this end, a temperature sensor installation part (130) may be provided in the cover (100), and the temperature sensor (S) may pass through the temperature sensor installation part (130) to reach the third cold water channel (f3). Information measured by the temperature sensor (S) may be used to control the cooling unit (2).

[0134]

[0135] Meanwhile, in another embodiment of the present invention, a cold water tank assembly (1') may have both a first fluid transfer pipe (110') and a second fluid transfer pipe (120') formed in either the cover (100') or the case (200'). An embodiment in which both the first fluid transfer pipe (110') and the second fluid transfer pipe (120') are formed in the cover (100') is illustrated in FIG. 7.

[0136] In this case, the fluid introduced into the second fluid transfer pipe (120') can flow along the third cold water path (f3) and enter one end of the first cold water path (f1) and the second cold water path (f2). The fluid introduced into one end of the first cold water path (f1) and the second cold water path (f2) can flow toward the other end of the first cold water path (f1) and the second cold water path (f2) and be discharged to the outside through the first fluid transfer pipe (110').

[0137] In the case of an embodiment where the first fluid transfer pipe (110') is an inlet pipe, the fluid flowing into the first fluid transfer pipe (110') can flow into the other end of the first cold water path (f1) and the second cold water path (f2). The fluid flowing into the other end of the first cold water path (f1) and the second cold water path (f2) can flow toward one end of the first cold water path (f1) and the second cold water path (f2) and be discharged to the outside through the second fluid transfer pipe (120').

[0138] In the embodiment illustrated in FIG. 7, the temperature sensor (S') can pass through the temperature sensor mounting portion (130') formed in the cover (100) and reach the first cold water flow path (f1) or the second cold water flow path (f2). Information measured by the temperature sensor (S') can be used to control the cooling portion (2).

[0139] In another embodiment of the present invention, one or more reinforcing ribs (140') may be formed on the outer surface of a configuration (cover or case) in which a first fluid transfer pipe (110'), a second fluid transfer pipe (120'), and a temperature sensor installation part (130') are installed. The reinforcing ribs (140') may be, for example, a structure that extends outwardly with a predetermined height along a radial direction, and as they extend, they may connect the first fluid transfer pipe (110'), the second fluid transfer pipe (120'), and the temperature sensor installation part (130'). Accordingly, the durability of the configuration (cover or case) in which the reinforcing ribs (140') are formed may be improved.

[0140]

[0141] Hereinafter, a water purifier (10) including a cold water tank assembly (1) according to an embodiment of the present invention will be described in detail.

[0142]

[0143] A water purifier (10) according to an embodiment of the present invention includes a cold water tank assembly (1), a cooling unit (2), a pump (3), a water purification unit (4), and a water outlet unit (5).

[0144]

[0145] The cooling unit (2) is configured to cool the fluid flowing in from the outside to produce cold water.

[0146] Referring to FIG. 14, the cooling unit (2) includes a cooling channel member (310), a cooling module (320), a heat dissipation member (330), and a cooling unit cover (340).

[0147]

[0148] In the cooling channel member (310), an inlet (311) communicating with the first fluid flow pipe (110) of the cold water tank assembly (1) and an outlet (312) communicating with the outlet (5) or the second fluid flow pipe (210) of the cold water tank assembly (1) are formed. Additionally, the cooling channel member (310) provides a space (C) through which fluid can flow. In the space (C), a plurality of cooling channel ribs (313) that divide the space (C) into a plurality of partitioned spaces may be located. The plurality of cooling channel ribs (313) may be alternately arranged on the left or right side so that the length of the channel formed within the space (C) is maximized, thereby increasing the contact area and time with the cooling module (320) and improving cooling efficiency.

[0149]

[0150] The cooling module (320) may be configured to cover the space (C) of the cooling channel member (310), and may be provided as a thermoelement, for example. The cooling module (320) may be electrically connected to an external control power source (not shown) to receive power and control signals, so that one side is cooled and the opposite side facing the one side is heated.

[0151] As one side of the cooling module (320) is cooled, heat exchange occurs with the fluid in the space (C), and the fluid that has undergone heat exchange is cooled to generate cold water. In other words, the fluid introduced through the inlet (311) of the cooling channel member (310) flows along the space (C) and is cooled by the cooling module (320) to generate cold water, and the generated cold water is discharged to the outside through the outlet (312).

[0152]

[0153] A heat dissipation section (330) may be disposed on the heated opposite side of the cooling module (320). The heat dissipation section (330) includes a pipe installation section (331), a pipe (332), and a heat dissipation plate (333).

[0154] One side of the pipe installation part (331) is connected to the heated opposite side of the cooling module (320), and a guide groove for installing the pipe (332) is formed on the other side. Accordingly, as one side of the cooling module (320) cools, the heat generated is conducted sequentially through the pipe installation part (331) and the pipe (332) and can be discharged to the outside through the heat sink (333).

[0155]

[0156] The cooling unit cover (340) is configured to cover at least a portion of the cooling module (320) and the heat dissipation unit (330), and the cooling efficiency can be improved by minimizing the external exposure area of ​​the cooling module (320).

[0157]

[0158] In another embodiment of the present invention, the cover (100) and case (200) constituting the cold water tank assembly (1) are formed of a metal material, and the cooling part (2) may be directly connected to the cold water tank assembly (1) to directly cool the cold water tank assembly (1).

[0159]

[0160] The pump (3) can be installed on a flow line through which fluid flows and provides power for fluid flow.

[0161]

[0162] The water purification unit (4) includes one or more filters that filter out foreign substances contained in the fluid flowing in from the outside, and in the water purifier according to the embodiment of the present invention, the water purification unit (4) may be located upstream of the cold water tank assembly (1). As a result, only purified water filtered by the water purification unit (4) can be introduced into the cold water tank assembly (1).

[0163]

[0164] The water outlet (5) is configured to discharge fluid toward the outside, and the user can receive purified water, hot water, or cold water through this.

[0165]

[0166] Hereinafter, the flow path in a water purifier (10) according to one embodiment of the present invention will be specifically described with reference to FIGS. 9 and 10.

[0167] Referring to FIGS. 9 and 10, the cold water tank assembly (1) can be connected to the outlet (5) through the first flow line (L1). In one embodiment, a pump (3) can be installed on the first flow line (L1) to provide power for fluid flow.

[0168] At one point of the first flow line (L1), a first cooling channel (L2) communicating with the cooling section (2) may be branched off from the first flow line (L1).

[0169] A first flow path switching member (6) may be installed at the branching point of the first flow line (L1) and the first cooling flow path (L2). The first flow path switching member (6) enables the first fluid transfer pipe (110) of the cold water tank assembly (1) to communicate with either the cooling section (2) or the water outlet section (5) through operation. When the first fluid transfer pipe (110) communicates with the cooling section (2) through the operation of the first flow path switching member (6), the process of generating cold water by the cooling section (2) is performed, and when the first fluid transfer pipe (110) communicates with the water outlet section (5), the fluid flowing through the cold water tank assembly (1) is discharged to the outside through the water outlet section (5).

[0170] Meanwhile, the cold water tank assembly (1) can be connected to the water purification unit (4) through the second flow line (L4).

[0171] At one point of the second flow line (L4), a second cooling channel (L3) communicating with the cooling section (2) may be branched off from the second flow line (L4).

[0172] A second flow path switching member (7) may be installed at the branching point of the second cooling flow path (L3) and the second flow line (L4). The second flow path switching member (7) enables the second fluid transfer pipe (210) of the cold water tank assembly (1) to communicate with either the cooling section (2) or the water purification section (4) through operation. When the second fluid transfer pipe (210) communicates with the cooling section (2) through the operation of the second flow path switching member (7), cold water generated in the cooling section (2) can flow into the cold water tank assembly (1), and when the second fluid transfer pipe (210) communicates with the water purification section (4), purified water can flow into the cold water tank assembly (1).

[0173]

[0174] A water purifier (10) according to one embodiment illustrated in FIGS. 9 and 10 can operate in any one of a cold water extraction mode, a drain mode, and a cold water generation mode.

[0175] In the cold water generation mode, the first flow path switching member (6) is switched toward the cooling unit (2), and the second flow path switching member (7) is switched toward the cold water tank assembly (1). At this time, when the pump (3) is operated, the fluid circulates through the first flow line (L1), the first cooling flow path (L2), the cooling unit (2), the second cooling flow path (L3), the second flow line (L4), and the cold water tank assembly (1), and is continuously cooled by the cooling unit (2) (see FIG. 9). The cold water generation mode can be continuously performed until the temperature measured by the temperature sensor (S) reaches a preset temperature.

[0176]

[0177] In the cold water extraction mode and drain mode, the first flow path switching member (6) is switched toward the water outlet (5) side, and the second flow path switching member (7) is switched toward the water purification section (4) side. At this time, when the pump (3) is operated, raw water flows into the water purification section (4) to produce purified water, and the produced purified water flows into the cold water tank assembly (1) through the second flow line (L4), causing the cold water remaining inside the cold water tank assembly (1) to be directed toward the water outlet (5) side (see FIG. 10). In another embodiment, cold water extraction or residual water drainage through the water outlet (5) can be performed using only raw water pressure without the operation of the pump (3).

[0178]

[0179] Hereinafter, a flow path system in a water purifier (10) according to another embodiment of the present invention will be described in detail with reference to FIGS. 11 and 12.

[0180] Referring to FIGS. 11 and 12, the cold water tank assembly (1) can be connected to the cooling unit (2) through the first cooling channel (L2'). In one embodiment, a pump (3) can be installed on the first cooling channel (L2') to provide power for fluid flow.

[0181] Additionally, the cold water tank assembly (1) may be connected to the cooling section (2) through the second cooling channel (L3'), and at one point of the second cooling channel (L3'), a third flow line (L5) connected to the outlet section (5) may be branched off from the second cooling channel (L3').

[0182] A first flow path switching member (6') may be installed at the branching point of the second cooling flow path (L3') and the third flow line (L5). The first flow path switching member (6') causes the outlet (312) of the cooling unit (2) to communicate with either the water outlet (5) or the cold water tank assembly (1) through operation. When the cooling unit (2) communicates with the cold water tank assembly (1) through the operation of the first flow path switching member (6'), the process of generating cold water by the cooling unit (2) is carried out, and when the cooling unit (2) communicates with the water outlet (5), the cold water generated by the cooling unit (2) is discharged to the outside through the water outlet (5).

[0183] Meanwhile, the cold water tank assembly (1) can be connected to the water purification unit (4) through the second flow line (L4).

[0184] A second flow channel switching member (7) may be installed at the confluence point of the second flow line (L4) and the second cooling channel (L3'). The second flow channel switching member (7) enables the second fluid transfer pipe (210) of the cold water tank assembly (1) to communicate with either the cooling section (2) or the water purification section (4) through operation. When the second fluid transfer pipe (210) communicates with the cooling section (2) through the operation of the second flow channel switching member (7), cold water generated in the cooling section (2) can flow into the cold water tank assembly (1), and when the second fluid transfer pipe (210) communicates with the water purification section (4), purified water can flow into the cold water tank assembly (1).

[0185]

[0186] A water purifier (10) according to one embodiment illustrated in FIGS. 11 and 12 can also operate in any one of the cold water extraction mode, drain mode, and cold water generation mode.

[0187] In the cold water generation mode, the first flow path switching member (6') and the second flow path switching member (7) are switched toward the cold water tank assembly (1). At this time, when the pump (3) is operated, the fluid circulates through the first cooling flow path (L2'), the cooling section (2), the second cooling flow path (L3'), the second flow line (L4), and the cold water tank assembly (1), and is continuously cooled by the cooling section (2) (see FIG. 11). The cold water generation mode can be continuously performed until the temperature measured by the temperature sensor (S) reaches a preset temperature.

[0188]

[0189] In the cold water extraction mode and drain mode, the first flow path switching member (6') is switched toward the water outlet (5) side, and the second flow path switching member (7) is switched toward the water purification section (4) side. At this time, when the pump (3) is operated, raw water flows into the water purification section (4) to produce purified water, and the produced purified water flows into the cold water tank assembly (1) through the second flow line (L4), causing the cold water remaining inside the cold water tank assembly (1) to be directed toward the water outlet (5) side (see FIG. 12). In another embodiment, cold water extraction or residual water drainage through the water outlet (5) can be performed using only raw water pressure without the operation of the pump (3).

[0190]

[0191] According to the cold water tank assembly according to the embodiment of the present invention described above, the following effects are achieved.

[0192] First, compared to conventional cold water tanks, the cold water tank assembly has the effect of significantly improving cold water generation efficiency relative to the tank volume.

[0193] Second, as the cold water generation efficiency is improved, it is possible to miniaturize the water tank compared to conventional cold water tanks, and accordingly, there is an effect of enabling the miniaturization of the water purifier including the cold water tank assembly.

[0194] Third, multiple cold water channels with small cross-sectional areas are formed inside the cold water tank assembly, which can reduce the temperature variation of the cold water. Consequently, there is an effect of generating and providing cold water at a constant temperature to the user.

[0195] Fourth, since the cross-section of the cold water flow path formed inside the cold water tank assembly is circular, no air remains inside the cold water flow path. Accordingly, the problem of air remaining in the corners due to the polygonal cross-section of the conventional cold water tank assembly is resolved.

[0196] Fifth, the assembly of the cold water tank assembly can be completed solely by joining the screw threads of the cover and the case, which has the effect of improving manufacturing convenience.

[0197] Sixth, multiple cold water flow paths are formed in the cold water tank assembly, allowing it to accommodate a large amount of cold water relative to the volume of the cold water tank assembly. Accordingly, there is an effect that enables the supply of a large amount of cold water without the need for a separate tank for storing cold water.

[0198]

[0199] For the time being, the present specification has been described with reference to embodiments illustrated in the drawings so that those skilled in the art can easily understand and reproduce the present invention; however, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible from the embodiments of the present invention.
