Description

Technical Field

[0001] The present invention relates to a water outlet unit and a water purifier including the same.

Background Art

[0002] Generally, a water purifier is a device that supplies water from a water source such as a water supply, filters it into purified water, and then provides the purified water to a user. Such a water purifier can provide not only purified water but also warm water to the user.

[0003] Regarding this, the applicant's Korean Patent Publication No. 10-2018-0133611, "Faucet for Water Purifier" (Patent Document 1), discloses a water outlet pipe member, a faucet member coupled to an end of the water outlet pipe member, and a detachable jig detachably coupled to the faucet member. The water outlet pipe member of Patent Document 1 is composed of a cold and purified water supply pipe member for supplying cold water or purified water and a hot water pipe member for supplying hot water.

[0004] On the other hand, in order to provide warm water to the user, a water purifier immediately heats the purified water to 80 degrees or more with an instant hot water module (heater). Also, recent water purifiers can heat instant hot water to a higher temperature and provide warm water to the user. Such warm water vaporizes due to various causes such as pressure changes due to flow and vortex formation, generating bubbles, and the bubbles may flow out with the warm water. Therefore, when warm water flows out from the water purifier, there may be a problem that the discharged water flow of the warm water scatters in all directions due to the bubbles.

[0005] However, in the aforementioned Patent Document 1, only the configuration of the hot water pipe member formed to extend linearly is disclosed, and a configuration for removing the steam generated from the hot water pipe member for supplying hot water is not disclosed. Therefore, when the hot water flows out, the hot water cannot flow out in a straight form of water flow, and the problem of flowing out while scattering in all directions cannot be solved at all.

[0006] On the other hand, some researchers have recognized the aforementioned problem with bubbles when hot water is dispensed and have conducted research to remove the bubbles generated when hot water is dispensed from water purifiers.

[0007] In this regard, the applicant's Korean Patent Publication No. 10-2012-0075799, "Hot Water Discharge Valve" (Patent Document 2), discloses a hot water discharge valve that includes a discharge channel for discharging hot water and a bubble crushing member arranged in the discharge channel through which the hot water passes to remove bubbles from the hot water.

[0008] However, the bubble crushing member of the hot water discharge valve described in Patent Document 2 is formed in a mesh shape to allow hot water to pass through and is placed in the discharge channel, which has the problem that it may reduce the fluidity of the discharged hot water. In addition, the bubble crushing member of the hot water discharge valve described in Patent Document 1 has the problem that it makes the flow path structure of the water purifier more complex. Furthermore, because the bubble crushing member of Patent Document 2 may reduce the fluidity of hot water, residual water may remain in the flow path, which may reduce the hygiene of the water purifier.

[0009] Furthermore, the applicant's Korean Patent Publication 10-2013-0128591, "Steam Separation Apparatus" (Patent Document 3), discloses a lower body equipped with a steam outlet for discharging steam separated from hot water, a hot water outlet for discharging the hot water from which the steam has been separated to the outside, and a separation member for separating steam contained in the hot water, and an upper body equipped with a steam outlet.

[0010] However, the upper body, which is the superstructure of the steam separator, occupies a relatively large volume in the overall structure of the water purifier, making it difficult to apply the steam separator to water purifiers with a slim external shape. In addition, the steam emitted from the hot water outlet may cause condensation on the surfaces of other components of the water purifier located inside the water purifier, and this condensation may be discharged to the outside of the water purifier, causing inconvenience in use. Furthermore, the hot water outlet of the steam separator has a problem in that the upper part of the discharge flow path is exposed to atmospheric pressure, and no differential pressure is applied to the flow path, resulting in a very fast discharge rate of hot water, which causes the hot water to splash in all directions when it is discharged.

[0011] Thus, when hot water is dispensed, if it splashes in all directions, the user of the water purifier may suffer burns from the splashing water. Subsequently, the user may hesitate to use the hot water from the water purifier, potentially reducing its usability. In addition, during the process of dispensing hot water from the water purifier, the water flow may splash outside the container and contaminate surrounding objects.

[0012] Therefore, there is a need for technology that can separate the steam generated from the hot water in the water purifier and maintain a stable flow of hot water coming out of the water purifier. [Prior art documents] [Patent Documents]

[0014] The embodiments of the present invention were invented in view of the above-mentioned background, and aim to provide a water outlet unit that can mechanically separate steam from hot water and stably dispense hot water, and a water purifier including the same. Furthermore, the embodiment of the present invention aims to provide a water outlet unit and a water purifier containing the same that can reduce the formation of vortices caused by bubbles during the hot water extraction process. [Means for solving the problem]

[0015] A water purifier outlet unit according to one aspect of the present invention includes a first fluid pipe providing a first outlet passage for hot water outlet; and a second fluid pipe providing a second outlet passage for purified or cold water outlet, wherein the first fluid pipe includes a hot water pipe section; and a nozzle section extending from the lower end of the hot water pipe section and having an inner diameter smaller than the inner diameter of the hot water pipe section in a downward direction to delay the hot water outlet time.

[0016] Furthermore, the first fluid pipe may be further provided with a buffer section at the upper end of the hot water pipe section so that the steam generated from the hot water can remain stagnant.

[0017] Furthermore, the water purifier outlet unit is further equipped with a hot water supply pipe that communicates with the side of the hot water pipe and supplies the hot water to the hot water pipe, and the buffer section is positioned above the hot water supply pipe and can extend upward.

[0018] Furthermore, the hot water pipe section has a hot water inner diameter surface that slopes downwards so that the inner diameter decreases, and the first water outlet passage can be formed by the hot water inner diameter surface.

[0019] Further, the nozzle portion includes a first nozzle portion that continuously extends downward from the lower end portion of the hot water pipe portion and has a first inner diameter surface that slopes such that the inner diameter gradually decreases downward; and a second nozzle portion that continuously extends downward from the lower end portion of the first nozzle portion and has a second inner diameter surface that slopes less than the first inner diameter surface or extends parallel to the vertical direction.

[0020] Also, the thickness between the inner diameter and the outer diameter of the second nozzle portion is greater than the thickness between the inner diameter and the outer diameter of the first nozzle portion, and the thickness between the inner diameter and the outer diameter of the first nozzle portion may be greater than the thickness between the inner diameter and the outer diameter of the hot water pipe portion.

[0021] Also, the first flow pipe and the second flow pipe can be integrally formed.

[0022] A water purifier according to one aspect of the present invention includes a main body; and a water outlet unit installed in the main body for discharging hot water, purified water, or cold water. The water outlet unit includes a first flow pipe that provides a first water outlet passage for discharging hot water; and a second flow pipe that provides a second water outlet passage for discharging purified water or cold water. The first flow pipe includes a hot water pipe portion; and a nozzle portion that extends from the lower end portion of the hot water pipe portion and has an inner diameter smaller than the inner diameter of the hot water pipe portion in the downward direction to delay the hot water discharge time.

Advantages of the Invention

[0023] According to an embodiment of the present invention, by forming a steam buffer space above the first flow pipe through which hot water is discharged, it is possible to mechanically separate the steam of the hot water and reduce the formation of vortices by bubbles.

[0024] Also, according to an embodiment of the present invention, the steam stagnating in the steam buffer space can be used to push the hot water in the gravitational direction, thereby maintaining the hot water flow in a straight form.

[0025] Furthermore, according to the embodiment of the present invention, by providing a stabilization section where hot water stagnates at the lower part of the first fluid pipe from which hot water is discharged, the discharge time of the hot water can be delayed and the hot water can be stabilized, which significantly improves the ease of use of hot water for the user and contributes to maximizing the quality of the product.

[0026] Furthermore, according to the embodiment of the present invention, the thickness between the inner and outer diameters of the nozzle located on the lower side of the first fluid pipe is greater than the thickness between the inner and outer diameters of the nozzle located on the upper side of the first fluid pipe, thus preventing deformation of the nozzle due to the high temperature of the hot water.

[0033] As used herein, "includes" embodies a particular characteristic, domain, constant, step, operation, element and / or component, and does not exclude the presence or addition of other particular characteristics, domains, constants, steps, operations, elements, components and / or groups.

[0034] Furthermore, it should be made clear in advance that the terms "upper side," "lower side," etc., used in this specification are explained based on what is shown in the drawings, and may be expressed differently if the orientation of the object changes.

[0035] The specific configuration of a water purifier 1 according to one embodiment of the present invention will be described below with reference to the drawings.

[0036] Referring to Figures 1 to 3, the water purifier 1 can provide clean water to the user by filtering water supplied from an external source. Such a water purifier 1 may include a main body 100, a filter 200, a heater 300, a cooler 400, a flow path assembly 500, and a faucet 600.

[0037] Before going into detail, the water flowing into the water purifier 1 from the outside can be classified into raw water, purified water, chilled water, and hot water. In the following, water that has not passed through the filter 200 will be defined as raw water, and water that has been filtered through the filter 200 will be defined as purified water. Furthermore, of the water filtered through the filter 200, water cooled to a predetermined temperature or below by the cooler 400 will be defined as chilled water, and water filtered through the filter 200 and heated to a predetermined temperature or above by the heater 300 will be defined as hot water.

[0038] The main body 100 can provide the overall appearance of the water purifier 1. The main body 100 can be in the form of a case provided to enclose at least a portion of the main components of the water purifier 1. The main body 100 can be formed by assembling multiple covers and frames together with bolts or the like. The main body 100 can support various types of water purifier components for filtering raw water. For example, the main body 100 can support a filter 200, a heater 300, a cooler 400, and a flow path assembly 500.

[0039] The filter 200 can filter the raw water that flows into the water purifier 1 into purified water. Raw water can flow into the filter 200 from the flow channel 511 of the flow channel section 510, which will be described later. The purified water filtered by the filter 200 can flow into the first discharge channel 512 and the second discharge channel 513 of the flow channel section 510, which will be described later.

[0040] The heater 300 can provide hot water by heating purified water to a predetermined temperature or higher. The hot water provided by the heater 300 can be supplied to the water outlet unit 520, which will be described later, via the first discharge channel 512.

[0041] The cooler 400 can provide chilled water by cooling the purified water to a predetermined temperature or below. The chilled purified water provided by the cooler 400 can be supplied to the water outlet unit 520 via the second discharge channel 513.

[0042] The flow path assembly 500 is located inside the main body 100 and can provide pathways for raw water, hot water, and chilled purified water to flow within the main body 100. Such a flow path assembly 500 may include a flow path section 510, a water outlet unit 520, and a replacement tube module 530.

[0043] The flow path section 510 can provide a path through which raw water, hot water, and chilled purified water flow within the main body 100. Such a flow path section 510 may include a flow channel 511, a first discharge channel 512, and a second discharge channel 513.

[0044] The fluid flow channel 511 can provide a path for raw water flowing into the filter 200 from the outside, and a path for purified water filtered by the filter 200 to be discharged. The first discharge channel 512 branches off from the fluid flow channel 511 and can provide a path for purified water flowing from the filter 200 to the heater 300. The second discharge channel 513 branches off from the fluid flow channel 511 and can provide a path for purified water flowing from the filter 200 to the cooler 400.

[0045] Referring to Figures 4 and 5, the water outlet unit 520 can be supported by the main body 100. The water outlet unit 520 can be configured to discharge purified water, cold water, and hot water flowing through the replacement tube module 530 to the outside. For example, the water outlet unit 520 can be configured to discharge one of the purified water, cold water, and hot water to the outside, depending on the user's choice. The water outlet unit 520 can also be located on the front side of the main body 100 and can be open downwards.

[0046] A faucet 600 can be detachably connected to the lower end of the water outlet unit 520. The faucet 600 can guide hot water, purified water, or cold water supplied from the water outlet unit 520 to the outside. In this embodiment, the hot water, purified water, or cold water supplied from the water outlet unit 520 is supplied through the faucet 600, but is not limited to this; the hot water, purified water, or cold water may be supplied directly to the outside from the water outlet unit 520 without passing through a separate faucet 600.

[0047] Referring to Figures 6 and 8, such a water outlet unit 520 may include an outer pipe 521, a first fluid pipe 522, a second fluid pipe 523, a hot water supply pipe 524, a chilled purified water supply pipe 525, a first outlet 527, and a second outlet 528.

[0048] The outer pipe 521 can be a cover pipe that encloses the first fluid pipe 522 and the second fluid pipe 523. The outer pipe 521 can be integrally formed with at least a portion of the first fluid pipe 522 and the second fluid pipe 523. For example, one side of the outer pipe 521 can be integrally formed with a portion of the side wall of the first fluid pipe 522, and the other side of the outer pipe 521 can be integrally formed with a portion of the side wall of the second fluid pipe 523. In addition, at least a portion of the first fluid pipe 522 and the second fluid pipe 523 can be integrally formed.

[0049] The first fluidized pipe 522 can provide a first outlet passage 522a for the discharge of hot water. A hot water supply pipe 524 can be connected to the side of the first fluidized pipe 522 so as to extend in a vertical and offset direction. The first fluidized pipe 522 can be configured to communicate with the hot water supply pipe 524 below its upper end. In other words, the first fluidized pipe 522 can communicate with the hot water supply pipe 524 below the buffer section 522-3 described later. When hot water is supplied from the hot water supply pipe 524 to the first fluidized pipe 522, steam G generated from the hot water moves to the upper part of the first fluidized pipe 522, and the hot water from which some of the steam has been separated (H: hot water from which the steam has been released) can move to the lower part of the first fluidized pipe 522. By stagnating at the upper part of the first fluidized pipe 522, the steam G can push the hot water H from which the steam has been separated downwards (in the direction of gravity) of the first fluidized pipe 522.

[0050] Such a first fluid pipe 522 may include a hot water pipe section 522-1, a nozzle section 522-2, and a buffer section 522-3.

[0051] The hot water pipe section 522-1 can provide a flow path for hot water, which has passed through the hot water supply pipe 524, to flow to the nozzle section 522-2. The hot water pipe section 522-1 may have a hot water inner diameter surface 522-1a that slopes downward so that its inner diameter decreases. The inner wall of the first water outlet passage 522a provided in the hot water pipe section 522-1 may be formed by the hot water inner diameter surface 522-1a.

[0052] The nozzle portion 522-2 can be formed by extending from the lower end of the hot water pipe portion 522-1. The nozzle portion 522-2 may have an inner diameter smaller than the inner diameter of the hot water pipe portion 522-1 when extending downward. For example, the nozzle portion 522-2 may include a first nozzle portion 522-21 and a second nozzle portion 522-22 having an inner diameter smaller than such a first nozzle portion 522-21.

[0053] The first nozzle section 522-21 can extend continuously downward without a notch from the lower end of the hot water pipe section 522-1 and connect to the second nozzle section 522-22. The first nozzle section 522-21 may have a first inner diameter surface 522-21a that slopes downward so that its inner diameter gradually decreases. The gradient at which the inner diameter of the first nozzle section 522-21 decreases can be greater than the gradient at which the inner diameter of the hot water pipe section 522-1 decreases. In other words, the degree to which the inner diameter of the first nozzle section 522-21 decreases per unit length in the vertical direction can be greater than the degree to which the inner diameter of the hot water pipe section 522-1 decreases. The inner wall of the first water outlet passage 522a provided in the first nozzle section 522-21 can be formed by the first inner diameter surface 522-21a.

[0054] The first nozzle section 522-21 has a funnel-shaped inner diameter surface that becomes smaller than the inner diameter of the hot water pipe section 522-1 in the downward direction. As a result, a stabilization section can be created in the first nozzle section 522-21 where a portion of the hot water stagnates. In the stabilization section within the first nozzle section 522-21 where a portion of the hot water stagnates, the flow velocity of the hot water increases due to the narrower inner diameter surface, and the eddy phenomenon of the hot water is significantly reduced, thereby stabilizing the discharge of hot water.

[0055] Referring to Figure 7, the thickness between the inner and outer diameters of the first nozzle section 522-21 can be greater than the thickness between the inner and outer diameters of the hot water pipe section 522-1. Since the thickness between the inner and outer diameters of the first nozzle section 522-21 is greater than the thickness between the inner and outer diameters of the hot water pipe section 522-1, based on the same outer diameter, the first nozzle section 522-21 can have a funnel-shaped inner diameter surface that becomes smaller than the inner diameter of the hot water pipe section 522-1 towards the downward direction of the first fluid pipe 522.

[0056] The second nozzle portion 522-22 can extend continuously downward from the lower end of the first nozzle portion 522-21. The second nozzle portion 522-22 may have a second inner diameter surface 522-22a that is less inclined than the first inner diameter surface 522-21a or extends parallel to the vertical direction. The second inner diameter surface 522-22a can form the inner wall of the first water outlet passage 522a provided in the second nozzle portion 522-22.

[0057] If the first fluid pipe 522 has the same outer diameter and extends along the vertical direction, the thickness between the inner and outer diameters of the second nozzle portion 522-22 can be greater than the thickness between the inner and outer diameters of the first nozzle portion 522-21. Thus, the thickness between the inner and outer diameters of the first nozzle section 522-21 may be greater than the thickness between the inner and outer diameters of the hot water pipe section 522-1, and the thickness between the inner and outer diameters of the second nozzle section 522-22 may be greater than the thickness between the inner and outer diameters of the first nozzle section 522-21.

[0058] The buffer section 522-3 can provide a steam buffer space into which steam separated from the hot water can flow and accumulate. Such a buffer section 522-3 can extend above the hot water pipe section 522-1 and be provided above the hot water supply pipe 524. Alternatively, a buffer cap 522-31 can be provided detachably at the upper end of the hot water pipe section 522-1, which can selectively open the inside of the buffer section 522-3. When steam G moves to the upper part of the first fluid pipe 522, steam G contained in or generated from the hot water can enter the steam buffer space. The steam G flowing into the buffer section 522-3 can guide the water flow into a straight shape by pushing the hot water in the first fluid pipe 522 downward (in the direction of gravity).

[0059] The second fluid pipe 523 can provide a second outlet passage 523a for discharging purified or chilled water. The upper end of the second fluid pipe 523 can be connected in communication with the chilled purified water supply pipe 525. The second fluid pipe 523 can discharge purified or chilled water supplied from the chilled purified water supply pipe 525 to the outside of the faucet 600.

[0060] The hot water supply pipe 524 can provide a passage for hot water to flow through. The end of the hot water supply pipe 524 can be connected to the side of the first fluid pipe 522. The hot water supply pipe 524 can guide hot water heated to a certain temperature or higher by the heater 300 to the first fluid pipe 522.

[0061] The chilled purified water supply pipe 525 can provide a passage for purified or chilled water to flow through. The end of the chilled purified water supply pipe 525 can be connected to the upper end of the second flow pipe 523. The chilled purified water supply pipe 525 can guide the purified or chilled water, which has passed through the filter and cooler, to the second flow pipe 523.

[0062] The first outlet 527 may be a hole for extracting hot water. The first outlet 527 can be located at the end of the first fluid pipe 522. The first outlet 527 can be detachably connected to communicate with the top of the faucet 600. For example, hot water supplied from the first discharge channel 512 can move downward through the first outlet passage 522a and flow into the interior of the faucet 600. The second outlet 528 may be a hole for extracting chilled purified water. The second outlet 528 can be located at the end of the second flow pipe 523. The second outlet 528 can be detachably connected to communicate with the top of the faucet 600. The chilled purified water supplied from the second discharge channel 513 can flow downward through the second outlet passage 523a and into the interior of the faucet 600. These first outlet 527 and second outlet 528 can be located adjacent to each other. Returning to Figure 2, the replacement tube module 530 can provide a passage connecting the first discharge channel 512 and the first outlet 527, and a passage connecting the second discharge channel 513 and the second outlet 528. This replacement tube module 530 can be detachably coupled to the outlet unit 520.

[0063] The faucet 600 can be detachably coupled to the outlet unit 520 so as to communicate with the outlet unit 520. The lower part of the faucet 600 can extend to the underside of the main body 100. The upper part of the faucet 600 can be coupled to the outlet unit 520 within the main body 100. Hot water and cold water or purified water flowing out from the outlet unit 520 can be discharged to the underside of the faucet 600.

[0064] The following describes the effects and benefits of water purifier 1 having the configuration described above.

[0065] When hot water from the water purifier is supplied to the user, and the hot water is supplied from the hot water supply pipe 524 to the first fluid pipe 522, some of the steam G generated from the hot water moves to a steam buffer space provided at the top of the first fluid pipe 522 and can remain stagnant in the steam buffer space. The steam G stagnant in the steam buffer space pushes the hot water downward (in the direction of gravity) of the first fluid pipe 522, allowing the hot water to be discharged in a stable flow without splashing around.

[0066] Furthermore, since the first flow pipe 522 from which the hot water is discharged has a shape that narrows its inner diameter, the flow velocity of the hot water increases, and the eddy phenomenon of the hot water is significantly reduced, thereby stabilizing the discharge of hot water.

[0067] Although embodiments of the present invention have been described above as specific examples, these are merely illustrative, and the present invention is not limited thereto, but should be interpreted as having the broadest scope of the technical idea disclosed herein. Those skilled in the art can combine / substitute the disclosed embodiments to carry out patterns of shapes not indicated, and this will not depart from the scope of the present invention. Furthermore, those skilled in the art can easily modify or transform the embodiments disclosed herein, and it is clear that such modifications or transformations also fall within the scope of the present invention.
