Abstract

A hydrogen water generator includes a water supply part including a water supply passage including an inlet and an outlet; a water tank coupled to the outlet for receiving and storing water supplied to the inlet; an electrode module coupled to the water tank for generating hydrogen to generate hydrogen water in the water tank; and a water outlet for discharging the hydrogen water stored in the water tank. The water supply passage includes a delayed discharge outlet which is a portion of the water supply passage having a smallest cross-sectional area of a flow path in the water supply passage.

First claim

What is claimed is:

1. A hydrogen water generator comprising:
a water supply part including a water supply passage including an inlet and an outlet;
a water tank coupled to the outlet for receiving and storing water supplied to the inlet;
an electrode module coupled to the water tank for generating hydrogen to generate hydrogen water in the water tank; and
a water outlet for discharging the hydrogen water stored in the water tank, wherein
the water supply passage includes a delayed discharge outlet which is a portion of the water supply passage having a smallest cross-sectional area of a flow path in the water supply passage;
wherein the water supply part further comprises:
a first passage body including a first flow path, the first passage body including the inlet at one end portion the first flow path,
a second passage body including a second flow path, the second passage body including the outlet at one end portion of the second flow path,
wherein the delayed discharge outlet is disposed at an other end portion of the first flow path of the first passage body, and an other end portion of the second flow path of the second passage body couples with the other end portion of the first flow path of the first passage body, and

a cross-sectional area of the other end portion of the second flow path is wider than the cross-sectional area of the delayed discharge outlet,
wherein the outlet is formed as an opening that opens toward one side of the water supply part and the outlet has a width in a horizontal direction longer than a height in a vertical direction.

2. The hydrogen water generator of claim 1 , wherein
a cross-sectional area of the first flow path of the first passage body increases going towards the inlet and decreases going towards the delayed discharge outlet.

3. The hydrogen water generator of claim 2 , wherein
the cross-sectional area of the first flow path of the first passage body increases slowly towards the inlet relative to a decrease in the cross-sectional area of the first flow path of the first passage body towards the delayed discharge outlet, and
the cross-sectional area of the first flow path of the first passage body decreases rapidly towards the delayed discharge outlet relative to the increase in the cross-sectional area of the first flow path of the first passage body towards the inlet.

4. The hydrogen water generator of claim 1 , wherein a portion of the water supply passage is bent such that the water from the inlet of the water supply passage changes in direction to flow to the outlet of the water supply passage.

5. The hydrogen water generator of claim 1 , wherein
the second passage body includes a flow guide surface that is curved and disposed at a surface of the second flow path of the second passage body where the water flowing from the delayed discharge outlet falls on.

6. The hydrogen water generator of claim 5 , wherein
the flow guide surface of the second passage body changes a flow direction of the water flowing in the second flow path of the second passage body with respect to the flow of the water from the delayed discharge outlet such that the water flows at least equal to or greater than a right angle.

7. The hydrogen water generator of claim 1 , wherein at least one of cross-sectional area of the delayed discharge outlet, the length of the outlet in the traverse direction, and the length of the outlet in the longitudinal direction is dimensioned such that the water flowing out of the outlet flows along a wall surface of the water tank.

8. The hydrogen water generator of claim 1 , wherein the water supply part including the first passage body and the second passage body is removably coupled to the water tank so that the water supply part is removable from the hydrogen water generator.

9. A hydrogen water generator comprising:
a water supply part including a water supply passage including an inlet and an outlet;
a water tank coupled to the outlet for receiving and storing water supplied to the inlet;
an electrode module coupled to the water tank for generating hydrogen to generate hydrogen water in the water tank; and
a water outlet for discharging the hydrogen water stored in the water tank,
wherein a portion of the water supply passage is bent such that the water from the inlet changes in direction to flow to the outlet,
wherein the outlet is formed as an opening that opens toward one side of the water supply part and the outlet has a width in a horizontal direction longer than a height in a vertical direction.

10. The hydrogen water generator of claim 9 , wherein
the water supply part further comprises:
a first passage body including a first flow path, the first passage body including the inlet at one end portion of the first flow path,
a second passage body including a second flow path, the second passage body including the outlet at one end portion of the second flow path, wherein

an other end portion of the first flow path of the first passage body couples with an other end portion of the second flow path of the second passage body, and
the portion of the water supply passage that is bent is a flow guide surface of the second flow path of the second passage body where the water flowing from the other end portion of the first flow path of the first passage body falls on.

11. The hydrogen water generator of claim 10 , wherein
the flow guide surface is curved such that a height of the curve is progressively reduced going towards the outlet.

12. The hydrogen water generator of claim 11 , wherein
a delayed discharge outlet is disposed at the other end portion of the first flow path of the first passage body, the delayed discharge outlet having a smallest cross-sectional area of a flow path in the water supply passage.

13. The hydrogen water generator of claim 12 , wherein
the flow guide surface is disposed at a surface of the second flow path of the second passage body where the water flowing from the delayed discharge outlet falls on.

14. The hydrogen water generator of claim 13 , wherein
the flow guide surface changes a flow direction of the water flowing in the second flow path of the second passage body with respect to the flow of the water from the delayed discharge outlet such that the water flows at least equal to or greater than a right angle.

15. The hydrogen water generator of claim 9 , wherein at least one of cross-sectional area of the delayed discharge outlet, the length of the outlet in the traverse direction, and the length of the outlet in the longitudinal direction is dimensioned such that the water flowing out of the outlet flows along a wall surface of the water tank.

16. The hydrogen water generator of claim 15 , wherein the water supply part including the first passage body and the second passage body is removably coupled to the water tank so that the water supply part is removable from the hydrogen water generator.

17. A hydrogen water generator comprising:
a body;
a water supply part including
a first passage body including a first flow path, the first passage body including an inlet at one end portion the first flow path, the inlet opening toward a upper side of the body,
a second passage body including a second flow path, the second passage body including an outlet at one end portion of the second flow path, the outlet disposed at a lower position than the inlet,
a delayed discharge outlet at an other end portion of the first flow path of the first passage body, and an other end portion of the second flow path of the second passage body couples with the
