Concentrated liquid adding control system of water dispenser

Abstract

The invention discloses a concentrated liquid adding control system of a water dispenser. The concentrated liquid adding control system comprises a water purification tank (1), a normal-temperature-water water outlet valve connected with a normal-temperature-water water outlet of the water purification tank (1), a heat tank (4) connected with a hot-water water outlet of the water purification tank (1), a hot-water water outlet valve connected with a water outlet of the heat tank (4), a stepping motor (8) which is connected with concentrated liquid water inlets of the hot-water water outlet valve and the normal-temperature-water water outlet valve and a concentrated liquid bottle (6) connected with a water inlet of the stepping motor (8), wherein the water purification tank (1) is provided with a control board provided with a water level detection switch (2); the water level detection switch (2) is provided with a plurality of water purification detection points for detecting a water flow speed of the hot-water water outlet; the water level detection switch (2) and the stepping motor (8) are both connected with a main controller. According to the concentrated liquid adding control system of the water dispenser, disclosed by the invention, the problem that the use amount of concentrated liquid cannot be accurately controlled is effectively solved.

Description

technical field [0001] The invention relates to the technical field of water dispensers, in particular to a control system for adding concentrated liquid to a water dispenser. Background technique [0002] A water dispenser is a device that heats up or cools down bottled clean water or mineral water and makes it convenient for people to drink. Concentrated liquid needs to be added to the water of the water dispenser, such as adding mineral elements that are beneficial to the human body in the purified water, so that people can drink water safely and be healthier. [0003] In the prior art, the concentrate bottle is connected to the peristaltic pump, and the addition of the concentrated liquid is controlled by the peristaltic pump. As long as the water outlet button is pressed, the peristaltic pump will start or stop according to a fixed program, which cannot be dynamically adjusted at any time. For a fixed amount of concentrated liquid, the amount of concentrated liquid add...
