(21) The apparatus for manufacturing hydrogen-containing water according to certain embodiments of the disclosure will be described below in more detail with reference to the accompanying drawings, in which those components are rendered the same reference number that are the same or are in correspondence, regardless of the figure number, and redundant explanations are omitted.

(22) FIG. 1 is a cross-sectional view illustrating an example of an apparatus for manufacturing hydrogen-containing water, FIG. 2 is a perspective view illustrating an example of an apparatus for manufacturing hydrogen-containing water from which a receptacle is separated out, FIG. 3 is a perspective view illustrating the apparatus for manufacturing hydrogen-containing water of FIG. 2 which is partially disassembled, and FIG. 4 a perspective view illustrating the apparatus for manufacturing hydrogen-containing water of FIG. 2 which is partially vertically cut.

(23) Referring to FIG. 1 to FIG. 4, an apparatus for manufacturing hydrogen-containing water 10 according to an example includes a container part 100, a connecting part 200, a handle part 300, a filter part 400, and a receptacle 500.

(24) An upper space 101 and a lower space 103, which receive water, may be formed in the container part 100. The upper space 101 and the lower space 103 may be disposed up and down about the connecting passage 105, respectively. The upper space 101 may be disposed on the upper side of the lower space 103 and the connecting passage 105 may be disposed between the upper space 101 and the lower space 103. That is, in the apparatus for manufacturing hydrogen-containing water 10, the upper space 101 where a cathode 121 (see FIG. 5) is installed and the lower space 103 wherein an anode 123 (see FIG. 5) is installed may be formed in one container, that is, in the container part 100.

(25) The container part 100 may have an opened upper surface. As a result, the hydrogen-containing water generated in the upper space 101 can be discharged to the outside through the opened upper surface of the container part 100.

(26) FIG. 5 is an enlarged view of a portion A in FIG. 1.

(27) Referring to FIG. 5, an ion exchange membrane 110 and an electrolytic part 120 may be coupled to the container part 100.

(28) The ion exchange membrane 110 does not allow water to pass, but does allow positive ions, for example, hydrogen ions (H.sup.+) to pass.

(29) The ion exchange membrane 110 may be a cation exchange membrane.

(30) The ion exchange membrane 110 may be coupled to the container part 100 to close the connecting passage 105. The water contained in the upper space 101 cannot move to the lower space 103 and the water contained in the lower space 103 cannot move to the upper space 101.

(31) The electrolytic part 120 can electrolyze the water contained in the container part 100.

(32) The electrolytic part 120 may include the cathode 121 and the anode 123. The cathode 121 may be coupled to the container part 100 to be disposed on the upper space 101 and the anode 123 may be coupled to the container part 100 to be disposed on the lower space 103. This means that the cathode 121 may be disposed in the upper space 101 or disposed on the upper space 101 of the connecting passage 105 around the ion exchange membrane 110, while the anode 123 may be disposed in the lower space 103 or disposed on the lower space 103 of the connecting passage 105 around the ion exchange membrane 110.

(33) The chemical reaction equations in the cathode 121 and the anode 123 are as follows.

(34) ##STR00001##

(35) Referring to Scheme 1, hydrogen (H.sub.2) and hydroxide ions (OH.sup.−) may be generated in the upper space 101 and oxygen (O.sub.2) may be generated in the lower space 103. Meanwhile, a part of oxygen (O.sub.2) generated in the lower space 103 may be converted into ozone (O.sub.3) by reaction with water contained in the lower space 103 as shown in the following Scheme 2.

(36) ##STR00002##

(37) Referring to Schemes 1 and 2, hydrogen ions (H.sup.+) may be generated in addition to oxygen (O.sub.2) and ozone (O.sub.2) in the lower space 103. The hydrogen ions (H.sup.+) may move to the upper space 101 through the ion exchange membrane 110 and be converted into hydrogen H.sub.2) in the cathode 121.

(38) Hydrogen (H.sub.2) may be dissolved in water contained in the upper space 101 to generate hydrogen-containing water because of its high solubility in water. Particularly, since hydroxide ion (OH.sup.−) coexists in the upper space 101, alkalescence hydrogen-containing water may be generated. On the other hand, since oxygen (O.sub.2) exists in a substantially gaseous state at room temperature, the pressure in the lower space 103 may be increased. Since ozone (O.sub.3) is in an unstable state as it is, it is mostly dissolved in water or decomposed or spontaneously reduced to be converted into oxygen (O.sub.2). However, since ozone (O.sub.3) caused discomfort due to its distinctively pungent smell even with an extremely small amount, or has harmful effects on the human body, any appropriate treatment therefor is required.

(39) A first sealing member 130 and a second sealing member 140 may be interposed between the cathode 121 and the anode 123 to prevent leakage.

(40) The first sealing member 130 may be disposed between the ion exchange membrane 110 and the cathode 121 to be in close contact with the ion exchange membrane 110 and the inner circumferential surface of the connecting passage 105. The second sealing member 140 may be disposed between the exchange membrane 110 and the anode 123 to be in close contact with the ion exchange membrane 110 and the inner circumferential surface of the connecting passage 105. The first sealing member 130 and the second sealing member 140 may prevent the water contained in the upper space 101 and the water contained in the lower space 103 from leaking and mixing with each other through the joining portion between the container part 100 and the ion exchange membrane 110.

(41) The first sealing member 130 and the second sealing member 140 may be formed of, for example, an O-ring of a silicon material.

(42) The connecting part 200 may connect the container part 100 and the handle part 300.

(43) The connecting part 200 may be formed in a curved shape. That is, one end of the connecting part 200 coupled to one side of the container part 100 may be horizontally extended, and the other end of the connecting part 200 coupled to the lower end of the handle part 300 may be extended upward.

(44) The connecting part 200 may have a double pipe structure fluidly connected to the lower space 103. That is, the connecting part 200 may include an outer pipe 210 and an inner pipe 220, which are respectively fluidly connected to the lower space 103. The outer pipe 210 can be coupled to the container part 100 and the inner pipe 220 may be disposed within the outer pipe 210 to be coupled to the outer pipe 230 via a first bracket 230. Meanwhile, an outlet formed at one side of the container part 100 may be formed to have a double pipe structure to be coupled to the connection portion 200 having the double pipe structure.

(45) The handle part 300 is coupled to the container part 100 through the connecting part 200 to simultaneously provide a supply passage for water to be supplied to the lower space 103 and a discharge passage to discharge oxygen and ozone generated from the lower space 103.

(46) FIG. 6 is a perspective view illustrating an example of a disassembled grip part and FIG. 7 is a perspective view illustrating a part of the grip part of FIG. 6 which is vertically cut.

(47) Referring to FIG. 6 and FIG. 7, the handle part 300 may include a pipe member 310 and a funnel member 320.

(48) The pipe member 310 may be coupled to the outer pipe 210 to extend upward. The pipe member 310 may be fluidly connected to the outer pipe 210.

(49) The funnel member 320 may be coupled to the inner pipe 220 and the upper outer circumferential surface of the funnel member 320 may be in close contact with the inner circumferential surface of the pipe member 310. On the other hand, a first gas discharge groove 321 may be formed on the upper outer circumferential surface of the funnel member 320. The first gas discharge groove 321 may be vertically extended to open at both ends.

(50) Thus, the water supplied to the funnel member 320 through the open upper surface of the pipe member 310 may be moved to the lower space 103 through the inner pipe 220, while oxygen(O.sub.2) and ozone(O.sub.3) generated in the lower space 103 and moved through the space between the outer pipe 210 and the inner pipe 220 may be moved upward through the space between the pipe member 310 and the funnel member 320 to be discharged to the outside sequentially through the first gas discharge groove and he open upper surface of the pipe member 310. The first gas discharge groove 321 may be formed in plural.

(51) The filter part 400 may be coupled to the handle part 300 and may filter the ozone(O.sub.3) generated in the lower space 103.

(52) FIG. 8 is a perspective view illustrating an example of a disassembled filter part and FIG. 9 is a perspective view illustrating a part of the filter part of FIG. 8 which is vertically cut.

(53) Referring to FIG. 8 and FIG. 9, the filter part 400 may include a lower case 410, an upper case 420, a filter member 430, a third sealing member 440, and a valve assembly 450.

(54) The lower case 410 may be detachably coupled to the upper case 420 and cooperate with the upper case 420 to form a receptive space to receive the filter member 430 and the valve assembly 450. The lower case 410 and the upper case 420 may be detachably coupled to each other to facilitate replacement of the filter member 430 and maintenance of the valve assembly 450.

(55) The lower case 410 may be seated in the funnel member 320.

(56) The lower case 410 may include a lower end pipe region 411, a tapered region 413, an outer pipe region 417, and an inner pipe region 419.

(57) The lower end pipe region 411 may be formed in a pipe shape. The lower pipe region 411 may be inserted into the funnel member 320.

(58) The tapered region 413 may be formed in a pipe shape that extends upward from the upper end of the lower end pipe region 411 and increases in diameter as the height increases. The tapered region 413 may be in close contact with the inner circumferential surface of the funnel member 320.

(59) The outer pipe region 417 may extend upward from the upper end of the tapered region 413 and may be formed in a pipe shape. A female screw may be formed on the inner circumferential surface of the outer pipe region 417 so as to be screwed to the upper case 420 on which a male screw is formed on the outer circumferential surface. As another example, a male screw may be formed on the outer circumferential surface of the outer pipe region 417 and a female screw may be formed on the inner circumferential surface of the upper case 420 so as to be screwed to each other.

(60) The inner pipe region 419 may protrude from the inner circumferential surface of the tapered region 413 to extend upward and may be formed in a pipe shape. The inner space of the inner pipe region 419 may be fluidly connected to the inner space of the lower end pipe region 411. A second gas discharge groove 414, a first through hole 415, and a second through hole 416 may be formed in the tapered region 413. The second gas discharge groove 414 may be formed in the outer circumferential surface of the tapered region 413 so that oxygen(O.sub.2) and ozone(O.sub.3) discharged through the first gas discharge groove 321 may be provided to the second through hole 416. The first through hole 415 may be formed at the lower end of the tapered region 413. The first through hole 415 may fluidly connect the inner space of the lower end pipe region 411 with the inner space of the inner pipe region 419. The second through hole 416 may be formed in the tapered region 413 to fluidly connect the inner space of the inner pipe region 419 with the second gas discharge groove 414. As a result, oxygen(O.sub.2) and ozone(O.sub.3) discharged through the first gas discharge groove 321 may be guided along the second gas discharge groove 414 and then pass through the second through hole 416 to reach the inner space of the inner pipe region 419. Meanwhile, the second gas discharge groove 414 and the second through hole 416 may be formed in plural.

(61) The upper case 420 may be formed in a vertically opened pipe shape.

(62) A network-structure mesh net 421 may be coupled to the open upper surface of the upper case 420.

(63) The filter member 430 may be disposed above the receptive space formed by the lower case 410 and the upper case 420.

(64) The filter member 430 may filter the ozone(O.sub.3) and allow the oxygen(O.sub.2) to pass among the oxygen(O.sub.2) and the ozone(O.sub.3) discharged from the lower space 103. The oxygen(O.sub.2) passed through the filter member 430 may be discharged to the outside through the mesh net 421.

(65) The third sealing member 440 may be coupled to the outer circumferential surface of the lower case 410 or the upper case 420. The third sealing member 440 may prevent the oxygen(O.sub.2) and the ozone(O.sub.3) discharged from the lower space 103 from discharging through the gap between the pipe member 310 and the filter part 400 without passing through the filter part 400.

(66) The third sealing member 440 may be made of, for example, an O-ring of a silicon material.

(67) The valve assembly 450 may be disposed below the receptive space formed by the lower case 410 and the upper case 420.

(68) The valve assembly 450 may open or close the opened upper surface of the inner pipe region 419 in accordance with the pressure in the lower space 103. Specifically, the valve assembly 450 may close the opened upper surface of the inner pipe region 419 when the pressure in the lower space 103 is less than a predetermined value, while it may open the opened upper surface of the inner pipe region 419 when the pressure in the lower space 103 is equal to or higher than a predetermined value The opened upper surface of the inner pipe region 419 can be opened. As a result, the valve assembly 450 can prevent the water contained in the lower space 103 from being poured through the handle part 300 even when the apparatus for supplying hydrogen-containing water 10 shakes or falls down and also prevent all kinds of devices including the ion exchange membrane 110, which are installed in or in contact with the lower space 103, from being damaged when the oxygen(O.sub.2) and the ozone(O.sub.3) generated in the lower space are accumulated to high pressure. The pressure of the lower space 103, which is a reference for opening/closing the opened upper surface of the inner pipe region 419 by the valve assembly 450, may be determined based on physical properties of various devices disposed in or contacted with the lower space 103, for example breaking strength of the ion exchange membrane 110 and the like

(69) FIG. 10 is a perspective view illustrating an example of a disassembled valve assembly and FIG. 11 a perspective view illustrating a part of the valve assembly of FIG. 10 which is vertically cut.

(70) Referring to FIG. 10 and FIG. 11, the valve assembly 450 may include a stopper 451, a second bracket 453, and an elastic member 455.

(71) The stopper 451 may be disposed on the upper side of the inner pipe region 419.

(72) The stopper 451 may be shaped to close the opened upper surface of the inner pipe region 419.

(73) The second bracket 453 may be disposed in the receptive space formed by the lower case 410 and the upper case 420 to be restrained from up-and-down movement. The second bracket 453 needs to be restrained from up-and-down movement to support the elastic member 455 to pressure the stopper 451 toward the inner pipe region 419.

(74) The second bracket 453 may be fixed to the inner circumferential surface of the lower case 410 or the upper case 420, but may be in close contact with the filter member 430 and the inner circumferential surface of the tapered area 413 to be restrained from up-and-down movement, instead of being fixed to the lower case 410 and the upper case 420 as shown. In the latter case, replacement of the filter member 430 and maintenance of the valve assembly 450 may be relatively easy.

(75) The second bracket 453 may be formed in a pipe shape having a flange protruded from the upper end inner circumferential surface to support the elastic member 455.

(76) The elastic member 455 may be engaged with the second bracket 453 and pressure the stopper 451 toward to the inner pipe region 419. The physical properties of the elastic member 455 such as the elastic modulus may be determined according to the pressure of the lower space 103, which is a reference for opening/closing the opened upper surface of the inner pipe region 419.

(77) The container part 100 may be mounted on the receptacle 500. Particularly, the receptacle 500 may have a structure on which the container part 100 can be detachably coupled, thereby enhancing user convenience. For example, a user can lift the container part 100 separated from the receptacle 500 and directly drink or pour into the cup to drink the hydrogen-containing water.

(78) A power terminal 510 for supplying electricity to various electric devices, for example, the electrolytic part 120, mounted on the container part 100 may be formed on the receptacle 500. The electricity supplied through the power terminal 510 may be stored in the battery 150 mounted on the container part 100. As a result, since hydrogen-containing water can be generated even when the container part 100 is disconnected from the receptacle 500 to be connected to an external power source in order to supply electricity to the power terminal 510, mobility and portability of the apparatus for manufacturing hydrogen-containing water 10 can be improved.

(79) The receptacle 500 may be provided with an input unit 520. A user may use the input part 520 to input an on-off signal of electric power to be supplied to various electric devices or the battery 150 mounted on the container part 100 through the power terminal 510 or to control power supply amount or power supply time. The user can adjust the hydrogen concentration by adjusting the power supply amount through the input unit 520 and adjust the hydrogen supply water production time by adjusting the power supply time through the input unit 520.

(80) FIG. 12 is a diagram illustrating an example of a control part.

(81) Referring to FIG. 12, an apparatus for manufacturing hydrogen-containing water 10 according to an example may further include a water level sensor 600, an alarm part 610, and a control part 620.

(82) The water level sensor 600 may detect the level of water contained in the lower space 103. The water level sensor 600 may be installed in the container part 100.

(83) The alarm part 610 may inform information on the need for water supply due to insufficient water contained in the lower space 103 to the outside. The alarm part 610 may be installed in the container part 100 or the receptacle 500. The alarm part 610 may include various information display devices, for example, LED lights, sirens, display devices, and the like.

(84) The control part 620 may drive the alarm part 610 to inform information on the need for water supply due to insufficient water contained in the lower space 103 to the outside when the water level detected by the water level sensor 600 is lower than a predetermined value. Through this, the user can determine the timing of water supply. The water level, which is a reference of the control part 620 for driving the alarm part 610, may be set to a minimum water level necessary for producing hydrogen-containing water, for example, a water level above which the anode 123 can be immersed.

(85) FIG. 13 a cross-sectional view illustrating an example of an apparatus for manufacturing hydrogen-containing water in which water is being supplied.

(86) Referring to FIG. 13, a user may supply water through the opened upper surface of the pipe member 310 after separating the filter part 400 from the handle part 300.

(87) The water supplied through the opened upper surface of the pipe member 310 may flow into the lower space 103 sequentially through the inner space of the funnel member 320 and the inner pipe 220. At this time, the gas filling a part of the lower space 103 may be discharged to the outside sequentially passing through the space between the outer pipe 210 and the inner pipe 220, the space between the pipe member 310 and the funnel member 320, and the first gas discharge groove 321 and finally through the opened upper surface of the pipe member 310.

(88) When the water supply is completed, The filter part 400 may be coupled to the handle part 300 as shown in FIG. 1. Oxygen(O.sub.2) and ozone(O.sub.3) may be continuously generated in the lower space 103 when the hydrogen-containing water production time elapses in the state where the filter part 400 is coupled to the handle part 300. However, since the upper surface of the inner pipe region 419 is closed by the stopper 451, oxygen(O.sub.2) and ozone(O.sub.3) are accumulated in the lower space 103, thereby increasing the pressure in the lower space 103.

(89) FIG. 14 is a cross-cross-sectional view illustrating an example of an apparatus for manufacturing hydrogen-containing water which is manufacturing hydrogen-containing water.

(90) Referring to FIG. 14, when the pressure of the lower space 103 becomes equal to or greater than a predetermined value, the stopper 451 that closes the upper surface of the inner pipe region 419 is raised while compressing the elastic member 455, so that the upper surface of the inner pipe region 419 may be opened. As a result, oxygen(O.sub.2) and ozone(O.sub.3) accumulated in the lower space 103 or newly generated in the lower space 103 may flow into the filter member 430 sequentially passing through the space between the outer pipe 210 and the inner pipe 220, the space between the pipe member 310 and the funnel member 320, the first gas discharge groove 321, the second gas discharge groove 414, the second through hole 416, and the inner pipe region 419.

(91) Oxygen(O.sub.2) may be discharged to the outside by passing through the filter member 430 across the mesh net 421, but ozone(O.sub.3) may be filtered by the filter member 430. Meanwhile, oxygen(O.sub.2) and ozone(O.sub.3) accumulated in the lower space 103 or newly generated in the lower space 103 may flow into the filter member 430 through a different path of the inner pipe 220, the inner space of the funnel member 320, the first through hole 415 and the inner pipe region 419 in order.

(92) While this disclosure includes specific examples, it will be apparent to one of ordinary skill in the art that various changes in form and details may be made in these examples without departing from the spirit and scope of the claims and their equivalents. The examples described herein are to be considered in a descriptive sense only, and not for purposes of limitation. Descriptions of features or aspects in each example are to be considered as being applicable to similar features or aspects in other examples. Suitable results may be achieved if the described techniques are performed in a different order, and/or if components in a described system, architecture, device, or circuit are combined in a different manner, and/or replaced or supplemented by other components or their equivalents. Therefore, the scope of the disclosure is defined not by the detailed description, but by the claims and their equivalents, and all variations within the scope of the claims and their equivalents are to be construed as being included in the disclosure.
