Description

Cold water generator

[0001] The present invention relates to a cold water generating device, and more specifically, to a cold water generating device having a structure that enables lightweighting while improving cooling efficiency.

[0002] A water purifier is a general term for any device that receives raw water, processes it, and then provides it to the user. A water purifier can filter raw water using various types of filters before providing it to the user. For example, a water purifier can filter raw water to make it suitable for drinking.

[0003] As living standards improve and consumer demands diversify, water purifiers that offer additional functions beyond simply filtering raw water are gaining popularity. For example, water purifiers that can provide hot water, cold water, and even ice are now on the market and selling well.

[0004] Typically, water purifiers designed to dispense cold water are equipped with a tank to hold purified water and a cooling system to cool the purified water contained in the tank. These types of water purifiers can be referred to as tank-type water purifiers. Tank-type water purifiers are widely used because they can dispense large volumes of cold water simultaneously.

[0005] For systems designed to cool purified water contained in a tank, power is typically required for operation. In particular, to achieve both miniaturization of the water purifier and cooling effect, these systems are often equipped with thermoelectric elements. As is well known, thermoelectric elements utilize the Peltier effect to perform cooling.

[0006] In water purifiers currently on the market, a thermoelectric element is incorporated into the tank itself that holds the purified water, thereby cooling the purified water. Therefore, when the thermoelectric element and its associated fan stop, the temperature of the cold water stored in the tank rises, and the thermoelectric element and its associated fan are configured to operate continuously.

[0007] However, tanks are typically formed with polygonal spaces. Therefore, some of the tank's space may be unfilled with purified or cold water, creating so-called "dead space." In this case, the generated cold water may stagnate within the tank, instead of flowing out first, resulting in a first-in, first-out pattern. If this stagnation persists, the stagnant cold water can become contaminated, potentially contaminating the entire tank.

[0008] Furthermore, because the thermoelectric element is formed with a small area compared to the tank, the cooling effect of the thermoelectric element is unlikely to extend to the entire tank space. Therefore, despite the presence of the thermoelectric element, there is a risk of reduced cooling efficiency.

[0009] Korean Patent No. 10-2036926 discloses a cooling device utilizing a thermoelectric element. Specifically, the device discloses a cooling device utilizing a thermoelectric element capable of providing cold water generated using the thermoelectric element in a direct water form.

[0010] However, the above-mentioned prior art document does not directly cool drinking water using a thermoelectric element, but rather provides a method for generating cooling water to cool drinking water. The above-mentioned prior art document does not provide a method for directly generating drinking cold water using a thermoelectric element.

[0011] Korean Patent Document No. 10-2128694 discloses a large-capacity, direct-type rapid-cooling drinking device. Specifically, the device discloses a large-capacity, direct-type rapid-cooling drinking device capable of generating cold water through heat exchange with the refrigerant by flowing cold water through a cold water coil extending around a refrigerant circulation coil.

[0012] However, the aforementioned prior art only provides a method for generating chilled water directly using a refrigerant and distributing it externally. It fails to provide a method for generating chilled water using a thermoelectric element, rather than a refrigerant, and distributing it externally.

[0013] Furthermore, the above-mentioned prior documents do not provide a method for re-cooling the cold water and then providing it to the outside when the temperature of the generated cold water is not sufficiently low.

[0120] The above opening can communicate the internal housing space (123) with the outside. The flow path part (400) accommodated in the internal housing space (123) can be coupled to the flow path support member (112) through the above opening and exposed to the outside.

[0121] The cooling member (200) substantially performs the function of cooling the fluid introduced into the cold water generation device (10). The cooling member (200) can cool the fluid by exchanging heat with the introduced fluid. In an embodiment where the fluid is purified water, the cooling member (200) can cool the purified water to produce cold water.

[0122] The cooling member (200) is electrically connected to the outside. The power and control signals required for the operation of the cooling member (200) can be transmitted from an external control power source (not shown).

[0124] The cooling member (200) is coupled to the flow path section (400). The cooling member (200) is fluidly connected to the flow path section (400). As will be described later, the flow path section (400) is fluidly connected to the direct flow path section (300), so it can be said that the cooling member (200) is fluidly connected to the direct flow path section (300) through the flow path section (400).

[0125] In the embodiments illustrated in FIGS. 7 to 15, the cooling member (200) includes a heat dissipation fin (210), a cooling module (220), a cooling cover (230), and a cooling path member (240).

[0126] The heat dissipation fin (210) constitutes a part of the cooling member (200). The heat dissipation fin (210) releases heat transferred to the cooling member (200), i.e., heat transferred from the purified water flowing into the cold water generation device (10), to the outside.

[0127] A heat dissipation fin (210) is coupled to a cooling module (220). The heat dissipation fin (210) can receive heat transferred from the purified water flowing inside the cooling module (220). A cooling pipe (221) provided in the cooling module (220) is penetrated and coupled to the heat dissipation fin (210). The heat dissipation fin (210) can be supported at a position spaced apart from the housing (100) by the cooling pipe (221).

[0128] The heat dissipation fin (210) may be provided in any form capable of dissipating the received heat to the outside. In the illustrated embodiment, the heat dissipation fin (210) is configured to include a plurality of plates that are stacked and spaced apart from each other in the height direction, i.e., the vertical direction. The plates are formed such that the length in the left-right direction is longer than the width in the front-back direction, and the thickness in the vertical direction is greater.

[0129] The cooling module (220) is a part where the cooling member (200) is connected to the housing (100). The cooling module (220) is mounted and supported on the upper side of the external housing (110). In addition, the cooling module (220) is configured to cool the introduced purified water.

[0130] The cooling module (220) is coupled to the heat dissipation fin (210). The heat transferred from the introduced water to the cooling module (220) can be transferred to the heat dissipation fin (210) and released to the outside.

[0131] The cooling module (220) is coupled to a cooling cover (230). One side of the cooling module (220) in the height direction, the upper side in the illustrated embodiment, is covered by the cooling cover (230). The cooling pipe (221) of the cooling module (220) can be supported by the cooling cover (230).

[0132] The cooling module (220) is coupled to the cooling channel member (240). The cooling module (220) covers a space formed inside the cooling channel member (240), i.e., a cooling channel space (242), and is coupled to the cooling channel member (240). The cooling module (220) may be configured to cool purified water flowing in the cooling channel space (242). In one embodiment, the cooling module (220) may come into contact with the purified water flowing in the cooling channel space (242) to exchange heat.

[0133] The cooling module (220) may be provided in any form capable of generating cold water by cooling purified water delivered to the cold water generation device (10). In one embodiment, the cooling module (220) may be provided as a thermoelement. In the above embodiment, the cooling module (220) may be electrically connected to an external control power source (not shown) to receive power and control signals.

[0134] The cooling module (220) may have a shape corresponding to the shape of the cooling channel member (240). In the illustrated embodiment, the cooling module (220) is formed in a polygonal plate shape having a length in the front-back direction, a width in the left-right direction, and a thickness in the up-down direction. At this time, the cross-sectional area of ​​the cooling module (220) is formed to be greater than the cross-sectional area of ​​the cooling channel space (242), so that the cooling module (220) can seal the cooling channel space (242).

[0135] In the illustrated embodiment, the cooling module (220) includes a cooling pipe (221).

[0136] The cooling pipe (221) is configured to connect the cooling module (220) to the heat dissipation fin (210). The cooling pipe (221) can support the heat dissipation fin (210). In addition, the cooling pipe (221) can form a passage for heat transferred from the water to the cooling module (220) to be transferred to the heat dissipation fin (210).

[0137] A cooling pipe (221) extends between the cooling module (220) and the heat dissipation fins (210). In the illustrated embodiment, the cooling pipe (221) comprises a portion extending horizontally and another portion extending vertically at a predetermined angle with the first portion. The other portion of the cooling pipe (221) is respectively penetrated and connected to a plurality of plates constituting the heat dissipation fins (210).

[0138] A plurality of cooling pipes (221) may be provided. The plurality of cooling pipes (221) may be spaced apart from each other in the width direction of the cooling module (220), in the left-right direction in the illustrated embodiment, and may be respectively connected to the heat dissipation fins (210) at different locations. In the illustrated embodiment, five cooling pipes (221) are provided, spaced apart from each other in the left-right direction, and respectively connected to the cooling module (220) and the heat dissipation fins (210).

[0139] The cooling cover (230) is configured to cover the cooling module (220). The cooling cover (230) covers one side of the cooling module (220) in the thickness direction, the upper side in the illustrated embodiment. Heat transferred to the cooling module (220) can be transferred to the heat dissipation fin (210) through the cooling pipe (221) without being arbitrarily released to the outside by the cooling cover (230). For this purpose, the cooling cover (230) can be formed of a material with low thermal conductivity.

[0140] The cooling cover (230) may have a shape corresponding to the shape of the cooling module (220). In the illustrated embodiment, the cooling cover (230) is formed in a polygonal plate shape having a length in the front-back direction, a width in the left-right direction, and a thickness in the up-down direction.

[0141] The cooling channel member (240) constitutes a part through which the fluid delivered to the cold water generator (10) flows. The introduced purified water flows in the cooling channel member (240) and can be cooled.

[0142] The cooling duct member (240) is coupled to the housing (100). The cooling duct member (240) can be coupled to and supported by the upper surface of the outer housing (110).

[0143] The cooling channel member (240) is coupled with the cooling module (220). The space formed inside the cooling channel member (240) (i.e., the cooling channel space (242)) can be covered and sealed by the cooling module (220). In the illustrated embodiment, one side in the height direction of the cooling channel member (240), i.e., the upper side, is coupled with the cooling module (220). The purified water flowing inside the cooling channel member (240) can be cooled by the cooling module (220).

[0144] The cooling channel member (240) is coupled to the flow channel member (400). The cooling channel member (240) is fluidly connected to the flow channel member (400) and can receive purified water. The cooling water generated by flowing through the cooling channel member (240) and being cooled by the cooling module (220) can be transferred to the direct water channel member (300) through the flow channel member (400).

[0145] Accordingly, it can be said that the cooling flow path member (240) is fluidly connected to the external and direct flow path members (300) through the flow path member (400).

[0146] The cooling channel member (240) may be formed of a material with high thermal conductivity. In one embodiment, the cooling channel member (240) may be formed of a stainless steel material.

[0147] In the cold water generation device (10) according to an embodiment of the present invention, the cold water generation process, i.e., the process of cooling purified water, is performed only in the cooling channel member (240). That is, the cooling module (220) may be configured to cool only purified water flowing in the cooling channel member (240).

[0148] Therefore, cold water can be generated even if other components, excluding the cooling channel member (240) among the components for fluid flow, i.e., the straight water channel section (300) and the flow channel section (400), are not formed of a material with high thermal conductivity.

[0149] Accordingly, compared to the case where the straight flow path section (300) and the flow path section (400) are formed of a heavy and expensive metal material, such as stainless steel, the straight flow path section (300) and the flow path section (400) can be formed of a lightweight and inexpensive material, such as synthetic resin.

[0150] As a result, the weight and manufacturing cost of the entire cold water generator (10) can be reduced, and manufacturing convenience can be improved.

[0151] Meanwhile, a temperature sensor (S) may be placed in the cooling channel member (240) (see FIGS. 24 and 27). The temperature sensor (S) may be placed on the upstream or downstream side of the cooling channel member (240) and may generate sensing information on the temperature of the incoming purified water or cold water or the temperature of the outgoing cold water.

[0152] The detection information generated by the temperature sensor (S) can be transmitted to a control unit (not shown) and used to calculate control information for controlling the operation of the circulation pump (440).

[0153] As best illustrated in FIGS. 13 to 15, the cooling channel member (240) includes a cooling channel body (241), a cooling channel space (242), a cooling channel rib (243), a cooling channel outlet (244), and a cooling channel inlet (245).

[0154] The cooling path body (241) constitutes the outer shape of the cooling path member (240). The cooling path body (241) is a portion where the cooling path member (240) is connected to the housing (100) and the cooling module (220).

[0155] A different configuration of a cooling channel member (240) is formed or combined in the cooling channel body (241). In the illustrated embodiment, a cooling channel space (242) and a cooling channel rib (243) are formed inside the cooling channel body (241). A cooling channel outlet (244) and a cooling channel inlet (245) are combined on the outside of the cooling channel body (241).

[0156] The cooling channel body (241) may have a shape corresponding to the shape of the cooling module (220). In the illustrated embodiment, the cooling channel body (241) is formed in a polygonal plate shape having a length in the front-back direction, a width in the left-right direction, and a thickness in the up-down direction.

[0157] A cooling path space (242) is formed inside the cooling path body (241).

[0158] The cooling passage space (242) is a space in which purified water transferred from the flow passage section (400) flows. The purified water flows in the cooling passage space (242) and can be cooled.

[0159] The cooling channel space (242) may have a shape corresponding to the shape of the cooling module (220) or the cooling channel body (241). In the illustrated embodiment, the cooling channel space (242) is formed as a polygonal plate-shaped space having a length in the front-back direction, a width in the left-right direction, and a thickness in the up-down direction.

[0160] In the above embodiment, one side of the cooling passage space (242) in the thickness direction, the remaining part except the upper side in the illustrated embodiment, i.e. the front side, the rear side, the left side, the right side and the lower side, can be surrounded by the cooling passage body (241).

[0161] One side in the thickness direction of the cooling passage space (242) is formed open and can be covered by the cooling module (220). The purified water flowing in the cooling passage space (242) can be cooled by coming into contact with the cooling module (220) through the one side.

[0162] The cooling passage space (242) can be divided into a plurality of small spaces that are interconnected by cooling passage ribs (243). The purified water introduced into the cooling passage space (242) flows along the plurality of small spaces, and the heat exchange time with the cooling module (220) can be increased. As a result, the cooling effect of the purified water can be improved.

[0163] The cooling passage space (242) is connected to the cooling passage outlet (244). The cooled water flowing in the cooling passage space (242) can flow out to the first circulation passage (431) through the cooling passage outlet (244).

[0164] The cooling passage space (242) is connected to the cooling passage inlet (245). The introduced purified water or pre-cooled purified water can flow into the cooling passage space (242) through the second circulation passage (432) and the cooling passage inlet (245).

[0165] The cooling path rib (243) divides the cooling path space (242) into a plurality of small spaces that are connected to each other. The cooling path rib (243) is positioned in the cooling path space (242) and is continuous with the inner circumference of the cooling path body (241) that surrounds the cooling path space (242).

[0166] The cooling path rib (243) may have any shape that can divide the cooling path space (242) into a plurality of small spaces that are interconnected. In the illustrated embodiment, the cooling path rib (243) is formed in a polygonal plate shape having a length in the front-back direction, a height in the up-down direction, and a thickness in the left-right direction.

[0167] At this time, the length in the front-back direction of the cooling channel rib (243) may be formed to be less than the length in the front-back direction of the cooling channel space (242). The purified water introduced into the cooling channel space (242) may flow along the space formed between the end of the cooling channel rib (243) and the inner surface of the cooling channel body (241) and be cooled.

[0168] A plurality of cooling path ribs (243) may be provided. The plurality of cooling path ribs (243) may be spaced apart from each other in the thickness direction, i.e., in the left-right direction in the illustrated embodiment.

[0169] At this time, some of the plurality of cooling channel ribs (243) may be continuous with one side of the inner circumference of the cooling channel body (241) in the longitudinal direction, i.e., the rear-side inner circumference in the illustrated embodiment. The remaining of the plurality of cooling channel ribs (243) may be continuous with the other side of the inner circumference of the cooling channel body (241) in the longitudinal direction, i.e., the front-side inner circumference in the illustrated embodiment.

[0170] Additionally, the cooling path ribs (243) of some of the above and the remaining cooling path ribs (243) of the above can be arranged alternately along the separation direction, i.e., the left-right direction in the illustrated embodiment.

[0171] Accordingly, a plurality of small spaces that are interconnected in a zigzag shape can be defined in the cooling passage space (242). As a result, the purified water flowing in the cooling passage space (242) also flows in a zigzag shape, and the heat exchange time with the cooling module (220) is increased, so that the cooling efficiency of the purified water can be improved.

[0172] The cooling channel outlet (244) constitutes a portion through which the cooling channel space (242) communicates with the outside. The cooling channel outlet (244) communicates the cooling channel space (242) with the circulation channel (430), specifically, the first circulation channel (431). The generated cold water can flow out into the first circulation channel (431) through the cooling channel outlet (244).

[0173] The cooling channel outlet (244) is coupled with the cooling channel body (241). The cooling channel outlet (244) is formed to extend from one side of the width direction of the cooling channel body (241), in the illustrated embodiment, from the left side.

[0174] The cooling flow outlet (244) is connected to and coupled with the cooling flow fitting member (453). The cooling flow outlet (244) is connected to the first circulation flow path (431) through the cooling flow fitting member (453).

[0175] The cooling channel inlet (245) constitutes another part through which the cooling channel space (242) communicates with the outside. The cooling channel inlet (245) communicates the cooling channel space (242) with the circulation channel (430), specifically, the second circulation channel (432). Purified water provided from the outside or cold water that is circulating can flow into the cooling channel space (242) through the second circulation channel (432) and the cooling channel inlet (245).

[0176] The cooling channel inlet (245) is coupled with the cooling channel body (241). The cooling channel inlet (245) is formed to extend from the other side in the width direction of the cooling channel body (241), in the illustrated embodiment, from the right side.

[0177] The cooling flow inlet (245) is connected to and coupled with the cooling flow fitting member (454). The cooling flow inlet (245) is connected to the second circulation flow path (432) through the cooling flow fitting member (454).

[0178] The direct water passage unit (300) stores the generated cold water. The direct water passage unit (300) is fluidly connected to the cooling member (200), specifically the cooling passage unit (240), and can receive and store the generated cold water. Therefore, the direct water passage unit (300) can be said to function as a type of tank.

[0179] In addition, due to the shape of the direct water passage part (300), the direct water passage part (300) may be configured to provide the generated cold water directly to the outside without storing it. In the above embodiment, it can be said that the cold water generation device (10) is provided in a direct water type. In the above embodiment, the purified water generated by the cooling member (200) may be provided directly to the outside through the direct water passage part (300) and the flow passage part (400) in sequence.

[0180] The direct flow path part (300) is coupled to the housing (100). The direct flow path part (300) is accommodated in the internal housing space (123) and supported by the internal housing body (121). The direct flow path part (300) is not arbitrarily exposed to the outside.

[0181] The direct flow path (300) is connected to the cooling member (200). Specifically, the direct flow path (300) can be connected to the cooling member (200) by the flow path (400). Cold water generated in the cooling member (200) can be delivered to the direct flow path (300).

[0182] The direct flow path section (300) is coupled to the flow path section (400). The direct flow path section (300) is connected to the flow path section (400) and can receive any fluid. For example, the direct flow path section (300) can receive purified water transmitted from the outside through the flow path section (400).

[0183] In addition, the direct flow path section (300) can receive cold water generated in the cooling member (200) through the flow path section (400). Furthermore, the cold water flowing in the direct flow path section (300) can be delivered to the outside through the flow path section (400) or circulated back to the cooling member (200).

[0184] As described above, the cold water generating device (10) according to the embodiment of the present invention is configured so that only the cooling member (200) performs the function of cooling purified water. Therefore, the direct water passage section (300) through which the generated cold water flows or is stored is not required to be formed of a material with high thermal conductivity.

[0185] Accordingly, as described above, the direct-flow guiding portion (300) can be formed of lightweight and inexpensive materials such as synthetic resin, thereby reducing weight and manufacturing costs and improving manufacturing convenience.

[0186] In the embodiments illustrated in FIGS. 16 to 19, the straight-line flow path (300) includes a first straight-line flow path (310), a second straight-line flow path (320), a bulkhead member (330), and a straight-line fitting member (340).

[0187] The first direct water passage (310) constitutes a portion of the direct water passage section (300). The first direct water passage (310) is a portion where purified water or previously generated cold water introduced from the outside flows into the direct water passage section (300). The first direct water passage (310) is connected to and connected with the first circulation passage (431) by a direct water fitting member (340), specifically, a first direct water fitting member (341).

[0188] The first direct water passage (310) is connected to and communicated with the second direct water passage (320). Clean or cold water flowing into the first direct water passage (310) can flow out into the second direct water passage (320). In the illustrated embodiment, one side in the height direction of the first direct water passage (310), i.e., the lower side, is connected to and communicated with the above-mentioned side, i.e., the lower side, of the second direct water passage (320).

[0189] A hollow space is formed within the first straight channel (310). The hollow space extends along the extension direction of the first straight channel (310). At this time, the cross-sectional area of ​​the hollow space may be formed to be larger than the cross-sectional area of ​​the hollow space formed within the second straight channel (320).

[0190] In addition, the cross-section of the hollow body may be formed in a circular shape. Accordingly, purified or cold water introduced into the first direct water passage (310) may be first-in, first-out (FIFO). In other words, the amount of purified or cold water stagnating in the first direct water passage (310) among the purified or cold water introduced may be minimized.

[0191] The first straight water passage (310) may be formed to accommodate a sufficient amount of purified or cold water. In other words, the first straight water passage (310) may be formed to have as long an extension length as possible. In the illustrated embodiment, the first straight water passage (310) extends in a helical shape.

[0192] The first direct current flow path (310) is connected to and connected with the second direct current flow path (320). In addition, the first direct current flow path (310) is formed to surround the second direct current flow path (320) radially outside.

[0193] The first straight flow path (310) is coupled to a bulkhead member (330). The first straight flow path (310) may be formed in a spiral shape by being wound around the bulkhead member (330). The bulkhead member (330) and the second straight flow path (320) may be sequentially arranged in the straight flow path hollow space (H) formed inside the first straight flow path (310).

[0194] The first direct current (310) can be divided into a plurality of parts. The plurality of parts constituting the first direct current (310) can be connected to each other and arranged in parallel along the radial direction.

[0195] In the illustrated embodiment, the first direct current flow path (310) includes a first external direct current flow path (310a) and a first internal direct current flow path (310b).

[0196] The first external straight flow path (310a) may be defined as a portion located radially outer among the portions of the first straight flow path (310). The first straight flow path (310a) surrounds the second straight flow path (310b) from the radially outer side. A first straight fitting member (341) is coupled to a radially outer end of the first external straight flow path (310a). A second straight fitting member (342) of the first internal straight flow path (310b) is coupled to a radially inner end of the first external straight flow path (310a).

[0197] The first internal straight flow path (310b) may be defined as a portion located radially inward among the portions of the first straight flow path (310). One side in the height direction of the first internal straight flow path (310b), in the illustrated embodiment, an upper end, is coupled and communicated with the first external straight flow path (310a). The other side in the height direction of the first internal straight flow path (310b), in the illustrated embodiment, a lower end, is coupled and communicated with the second straight flow path (320).

[0198] As the first direct water passage (310) is composed of the first external direct water passage (310a) and the first internal direct water passage (310b), the volume of the hollow space formed within the entire first direct water passage (310) can be increased. Accordingly, the flow rate of purified water or cold water that can flow in or be accommodated in the first direct water passage (310) can be increased. Accordingly, the flow rate of cold water provided externally can also be increased.

[0199] The second direct water passage (320) constitutes another part of the direct water passage section (300). The second direct water passage (320) receives purified or cold water that has passed through the first direct water passage (310). The purified or cold water that has entered the second direct water passage (320) may be provided to the outside through the flow passage section (400) or may be circulated along the flow passage section (400). The second direct water passage (320) is connected to the second circulation passage (432) by means of a direct water fitting member (340), specifically, a second direct water fitting member (342).

[0200] A hollow space is formed inside the second straight channel (320). The hollow space extends along the extension direction of the second straight channel (320). At this time, the cross-sectional area of ​​the hollow space may be formed to be smaller than the cross-sectional area formed inside the first straight channel (310).

[0201] In addition, the cross-section of the hollow body may also be formed in a circular shape. Accordingly, the purified or cold water flowing into the second direct water passage (320) may also be first-in, first-out, so that the purified or cold water stagnating in the second direct water passage (320) may be minimized.

[0202] The second straight water passage (320) may be formed to accommodate a sufficient amount of purified or cold water. In other words, the second straight water passage (320) may be formed to have as long an extension length as possible. In other words, the second straight water passage (320) is formed in a spiral shape.

[0203] The second direct water passage (320) is connected to and coupled with the first direct water passage (310). Clean water or cold water that has passed through the first direct water passage (310) can flow into the second direct water passage (320). In the illustrated embodiment, one side in the height direction of the second direct water passage (320), i.e., the lower side, is connected to and coupled with the one side, i.e., the lower side, of the first internal direct water passage (310b). The second direct water passage (320) can be fluidly connected to the first direct water passage (310) by a second direct water fitting member (342).

[0204] The second straight flow path (320) is coupled to the bulkhead member (330). The second straight flow path (320) is accommodated in the straight flow path hollow (H) formed inside the bulkhead member (330) and is positioned radially inward of the bulkhead member (330). The second straight flow path (320) is surrounded radially outward by the bulkhead member (330).

[0205] The bulkhead member (330) supports a first straight channel (310) and a second straight channel (320) that extend in a spiral shape. The first straight channel (310) is positioned radially outside the bulkhead member (330). The first straight channel (310) is wound around the bulkhead member (330).

[0206] A straight water passage hollow (H) defined by being surrounded by the bulkhead member (330) is formed on the radially inner side of the bulkhead member (330). The second straight water passage (320) is accommodated in the straight water passage hollow (H) and is arranged to face the first straight water passage (310) with the bulkhead member (330) interposed therebetween in the radial direction.

[0207] Accordingly, even if the first straight flow path (310) and the second straight flow path (320) are formed to have different cross-sectional areas, the spiral shape can be stably maintained by the bulkhead member (330).

[0208] The direct fitting member (340) is a configuration in which the direct flow path section (300) is coupled with another configuration, specifically, the flow path section (400). The direct fitting member (340) fluidly connects the first direct flow path (310) and the second direct flow path (320) to the flow path section (400), respectively.

[0209] A plurality of straight fitting members (340) may be provided. One of the plurality of straight fitting members (340) fluidly connects the first straight fitting passage (310) to the outside, thereby forming an inflow passage for purified or cold water. Another of the plurality of straight fitting members (340) fluidly connects the second straight fitting passage (320) to the outside, thereby forming an outflow passage for purified or cold water.

[0210] In the illustrated embodiment, the straight fitting member (340) includes a first straight fitting member (341) and a second straight fitting member (342).

[0211] The first direct fitting member (341) fluidly connects the first direct flow path (310) and the first circulation path (431). The first direct fitting member (341) is coupled to and communicates with the circulation inlet fitting member (455). Clean or cold water introduced into the first circulation path (431) can flow out into the first direct flow path (310) through the first direct fitting member (341).

[0212] The second direct fitting member (342) fluidly connects the first direct flow path (310) and the second direct flow path (320). The second direct fitting member (342) is connected and communicated with the lower end of the first internal direct flow path (310b) and the lower end of the second direct flow path (320), respectively. Clean or cold water flowing into the first direct flow path (310) can flow out into the second direct flow path (320) through the second direct fitting member (342).

[0213] The fluid path section (400) fluidly connects the outside and the direct flow path section (300). Purified water delivered from the outside can be delivered to the direct flow path section (300) through the fluid path section (400). Cold water contained in the direct flow path section (300) can be provided to the outside through the fluid path section (400).

[0214] In addition, the flow path section (400) fluidly connects the cooling path section (240) of the cooling member (200) and the direct water path section (300). The purified water delivered from the outside or the cold water that has been cooled by passing through the cooling path section (240) can be delivered to the direct water path section (300) through the flow path section (400).

[0215] That is, the flow path section (400) constitutes an inflow path of purified water and an outflow path of cold water with respect to the outside. At the same time, the flow path section (400) constitutes a circulation path of purified water or cold water. The purified water or cold water circulates through the cooling path member (240) along the flow path section (400) and, after being sufficiently cooled, can be received in the direct water path section (300) or provided to the outside.

[0216] Accordingly, as described above, the cooling efficiency of cold water can be improved.

[0217] The flow path section (400) is coupled to the housing (100). A portion of the flow path section (400) may be accommodated and supported by the flow path support member (112). The flow path section (400) is at least partially exposed to the outside of the housing (100).

[0218] The flow path section (400) is connected to and coupled with the cooling member (200). Specifically, the flow path section (400) can comprise an inlet path through which purified water or cold water flows into the cooling path section (240) and an outlet path through which water flows out from the cooling path section (240).

[0219] The flow path section (400) is connected to and connected with the direct water path section (300). Specifically, the flow path section (400) can form an inflow path through which purified water or cold water flows into the direct water path section (300) and an outflow path through which purified water or cold water flows out from the direct water path section (300).

[0220] As described above, the cold water generating device (10) according to the embodiment of the present invention is configured so that only the cooling member (200) performs the function of cooling purified water. Therefore, the flow path section (400) through which the generated cold water flows or is stored is not required to be formed of a material with high thermal conductivity.

[0221] Accordingly, as described above, the fluid path section (400) can be formed of lightweight and inexpensive materials such as synthetic resin, thereby reducing weight and manufacturing costs and improving manufacturing convenience.

[0222] In the embodiments illustrated in FIGS. 20 to 23, the flow path section (400) includes an inlet path (410), an outlet path (420), a circulation path (430), a circulation pump (440), a flow fitting member (450), and a fitting support member (460).

[0225] The outlet passage (420) is another configuration in which the flow passage section (400) is fluidly connected to the outside. The outlet passage (420) is located on the outside of the housing (100) and is fluidly connected to the outside. In an embodiment in which the cold water generating device (10) is provided in the water purifier, the outlet passage (420) can be fluidly connected to a faucet to provide cold water to the outside.

[0226] The outlet passage (420) is fluidly connected to the circulation passage (430), specifically, the second circulation passage (432). Cold water received in the direct water passage section (300) can be provided to the outside via the second circulation passage (432).

[0227] The circulation path (430) is a portion where the fluid path section (400) is connected to the cooling member (200) and the direct flow path section (300). The circulation path (430) is fluidly connected to the cooling path section (240), the first direct flow path (310), and the second direct flow path (320), respectively.

The first circulation path (431) is connected to a circulation pump (440) so that a transport force can be provided to purified water or cold water remaining in the first circulation path (4310).

[0233] The first circulation path (431) can be divided into a plurality of parts depending on the configuration to which it is coupled. In the illustrated embodiment, the first circulation path (431) is configured to include a part located on the front side and coupled and communicated with the inlet path (410) and the first direct water path (310), respectively, and another part located on the rear side and coupled and communicated with the cooling path outlet (244) and coupled with the circulation pump (440).

[0236] The second circulation path (432) constitutes a path through which purified water or cold water that has passed through the direct water path section (300) flows into the circulation path (430). The second circulation path (432) is connected to and communicates with the cooling path inlet (245), the outlet path (420), and the second direct water path (320), respectively. The purified water or cold water inside the second circulation path (432) can flow by the conveying force provided by the circulation pump (440).

[0237] The second circulation path (432) can be divided into a plurality of parts depending on the configuration to which it is coupled.

[0240] A detailed description of the process in which purified water or cold water is circulated along the circulation path (430) and re-cooled will be provided later.

[0241] The circulation pump (440) is coupled and communicated with the circulation path (430) to provide a transfer force to the interior of the circulation path (430). The circulation path (430) is coupled and communicated with the cooling path member (240), the direct water path section (300), the inflow path (410), and the outflow path (420), respectively, so it will be understood that the transfer force provided by the circulation pump (440) can be provided to purified water or cold water remaining in each component coupled and communicated with the circulation path (430).

[0242] The circulation pump (440) may be provided in any form capable of providing a transport force to the fluid. The circulation pump (440) may be electrically connected to an external control power source (not shown) to receive power and control signals necessary for operation.

[0263]

[0264] Referring to FIGS. 24 to 29, the flow of purified water or cold water formed inside a cold water generating device (10) according to an embodiment of the present invention is illustrated as an example.

[0265] As described above, the flow path section (400) can constitute an inflow path for purified water and an outflow path for cold water. At the same time, the flow path section (400) can constitute a circulation path for purified water or cold water.

[0266] Accordingly, inside the cold water generating device (10), either a flow for circulation of purified water or cold water (hereinafter, first flow (F1)) or a flow for inflow of purified water and outflow of cold water (hereinafter, second flow (F2)) can be formed.

[0267] Referring to FIGS. 24 to 26, a first flow (F1) formed in a cold water generating device (10) according to an embodiment of the present invention is illustrated as an example. The first flow (F1) may be defined as a flow in which purified water is provided to the cold water generating device (10), and the provided purified water circulates through the cold water generating device (10) and passes through the cooling channel member (240) multiple times to be re-cooled.

[0268] First, the first flow (F1) can be formed in a process in which purified water is continuously supplied from the outside.

[0269] In the above embodiment, the inlet fitting member (451) allows communication between the inlet flow path (410), the first circulation flow path (431), and the other part. Accordingly, purified water introduced from the outside passes through the inlet flow path (410) and the first circulation flow path (431) in sequence and is delivered to the direct water flow path section (300).

[0270] The purified water passing through the direct flow path (300) flows into the second circulation path (432). At this time, the outlet fitting member (452) is operated to allow communication between the above-mentioned part of the second circulation path (432) and the above-mentioned other part, but block communication between the above-mentioned part of the second circulation path (432) and the outlet path (420).

[0271] Accordingly, the purified water flowing into the second circulation path (432) is not discharged to the outside but is transferred to the cooling path member (240). The purified water flowing into the cooling path member (240) flows through the cooling path space (242) and is cooled and then transferred to the other part of the first circulation path (431).

[0272] Additionally, the first flow (F1) can be formed by circulating supplied purified water or generated cold water while the supply of purified water from the outside is blocked.

[0273] In the above embodiment, the inlet fitting member (451) blocks the communication between the inlet flow path (410) and the first circulation flow path (431), and allows the communication between the part of the first circulation flow path (431) and the other part. Accordingly, additional supply of purified water from the outside is blocked, and the introduced purified water and the generated cold water can be continuously re-cooled by circulating through the cooling flow path member (240), the direct water flow path section (300), and the circulation flow path (430).

[0274] Each of the above embodiments can be performed in accordance with the detection information generated by the temperature sensor (S) provided in the cooling channel member (240).

[0275] That is, if the temperature of the generated cold water is higher than the reference value based on the detection information generated by the temperature sensor (S), the control unit (not shown) can operate the circulation pump (440) to circulate the cold water. Accordingly, the generated cold water can be continuously reintroduced into the cooling channel member (240) and re-cooled.

[0276] If the temperature of the generated cold water is below a reference value based on the detection information generated by the temperature sensor (S), the control unit (not shown) can stop the circulation pump (440) to stop the circulation of the cold water.

[0277] Referring to FIGS. 27 to 29, a second flow (F2) formed in a cold water generating device (10) according to an embodiment of the present invention is illustrated as an example. The second flow (F2) can be defined as a flow in which the generated cold water is provided to the outside.

[0278] In the above embodiment, the inlet fitting member (451) blocks the connection between the inlet flow path (410) and the first circulation flow path (431). Accordingly, the supply of purified water from the outside is blocked, and the second flow (F2) can be formed only by the cold water generated by being provided to the cold water generating device (10).

[0279] When a user manipulates the faucet (not shown), cold water contained in the direct flow path (300) flows out to the second circulation path (432). At this time, the discharge fitting member (452) allows communication between a portion of the second circulation path (432) and the discharge path (420), but blocks communication between the portion of the second circulation path (432) and the other portion.

[0280] Accordingly, the cold water flowing into the second circulation path (432) can be provided to the outside through the outlet path (420).

[0281]

[0282] Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
