The controller moves the movable water discharger from an original position to a height with respect to a water container based on a sensing by the sensor. ## Claims ### Claim 1 A hydrogen water generator comprising: a water tank for receiving and storing water; an electrode module coupled to the water tank for generating hydrogen water; a movable water discharger; a transfer tube for transferring the hydrogen water from the water tank to the movable water discharger; a sensor; and a controller, wherein the controller is configured to move the movable water discharger from an original position to a height with respect to a water container based on a sensing by the sensor, wherein the sensor is configured to sense a level of the hydrogen water filled in the water container as the water container is filled with the hydrogen water discharged by the movable water discharger; and the controller is configured to move the movable water discharger such that a distance between the movable water discharger and the level of the hydrogen water remains constant and is limited by a predetermined range or value that prevents hydrogen from escaping the hydrogen water. ### Claim 2 (depends on 1) The hydrogen water generator of claim 1, wherein the controller is configured to move the movable water discharger to the height with respect to the water container based on at least one of a height and a size of the water container sensed by the sensor. ### Claim 3 (depends on 2) The hydrogen water generator of claim 2, wherein the controller is configured to limit the discharge of the hydrogen water from the movable water discharger when the height of the water container and a level of the filled hydrogen water in the water container is greater than or equal to a set threshold ratio. ### Claim 4 (depends on 2) The hydrogen water generator of claim 2, wherein the controller is configured to move the movable water discharger to the original position when the discharge of the hydrogen water is complete. ### Claim 5 (depends on 2) The hydrogen water generator of claim 2, wherein the controller is configured to cause the movable water discharger to partially fill the water container with hydrogen water, move the movable water discharger to make contact with an upper surface of the water container, and then completely fill the water container with hydrogen water. ### Claim 6 (depends on 2) The hydrogen water generator of claim 2, wherein the controller is configured to move the movable water discharger to make contact with an upper surface of the water container when the discharge of the hydrogen water is complete. ### Claim 7 (depends on 1) The hydrogen water generator of claim 1, further comprising another sensor, wherein the controller is configured to restrict an amount of pressure applied to an upper surface of the water container based on a pressure sensed by the another sensor during a contact between the movable water discharger and the upper surface of the water container. ### Claim 8 (depends on 1) The hydrogen water generator of claim 1, wherein the controller is configured to move the movable water discharger to make contact with an upper surface of the water container. ### Claim 9 (depends on 1) The hydrogen water generator of claim 1, wherein the movable water discharger comprises: a first casing; a second casing retractably inserted at the first casing; and a lifter, wherein the controller is configured to control the lifter to protrude the second casing from the first casing when the controller is adjusting the height between the movable water discharger and the water container. ### Claim 10 (depends on 9) The hydrogen water generator of claim 9, wherein the lifter comprises a motor, a pinion, and a rack. ### Claim 11 (depends on 9) The hydrogen water generator of claim 9, wherein the lifter comprises a pump, a cylinder, and a piston. ### Claim 12 (depends on 9) The hydrogen water generator of claim 9, wherein a portion of the transfer tube at the movable water discharger is elastic such that the transfer tube stretches when the second casing protrudes from the first casing. ### Claim 13 (depends on 9) The hydrogen water generator of claim 9, wherein the movable water generator further comprises a third casing retractably inserted in the second casing and another lifter, wherein the controller is configured to control the lifter and the another lifter so that the second casing protrudes from the first casing, and then the third casing protrudes from the second casing, and the controller is configured to control the lifter and the another lifter so that the third casing retracts to the second casing, and then the second casing retracts to the first casing. ### Claim 14 (depends on 1) An appliance comprising a body including the hydrogen water generator of claim 1. ### Claim 15 A hydrogen water generator comprising: a body including a first protrusion at an upper portion of the body, the first protrusion including a movable water discharger, and a second protrusion at a lower portion of the body facing the first protrusion, the second protrusion including a seating part in which a water container is seated;
