Liquid dispenser
In an example, a liquid dispenser is for dispensing liquid into a liquid reservoir with reduced foam formation. The liquid dispenser has a baffle element, guiding element and a discharge element. The baffle element is to receive liquid, the guiding element is to guide liquid from the baffle element to the discharge element, and the discharge element is to discharge liquid into the liquid reservoir. The baffle element, the guiding element and the discharge element are arranged in cascade to flow liquid from the baffle element to the discharge element.
1. A liquid dispenser for dispensing liquid into a liquid reservoir with reduced foam formation, the liquid dispenser comprising a baffle element, a guiding element a discharge element, and a hinge between the baffle element and the guiding element to adjust an angle therebetween;
wherein the baffle element is to receive liquid, the guiding element is to guide liquid from the baffle element to the discharge element, and the discharge element is to discharge liquid into the liquid reservoir; and
wherein the baffle element, the guiding element and the discharge element are arranged in cascade to flow liquid from the baffle element to the discharge element, and wherein the baffle element and the guiding element are vertically spaced from one another and the discharge element and the guiding element are vertically spaced from one another to form a waterfall-structure for the liquid.
2. The liquid dispenser according to claim 1 , further comprising an additional hinge to adjust an angle between the discharge element and the guiding element.
3. The liquid dispenser according to claim 1 , wherein the discharge element comprises a floating body to automatically adjust a vertical position of the discharge element to correspond to a liquid level in the liquid reservoir.
4. The liquid dispenser according to claim 1 , wherein the baffle element, the guiding element and the discharge element comprise plates to channel liquid.
5. The liquid dispenser according to claim 1 , wherein the baffle element comprises a fastening device to fasten the liquid dispenser to the liquid reservoir.
