Automatic perfusion water dispenser and method for controlling automatic perfusion

Abstract

The invention discloses an automatic perfusion water dispenser and a method for controlling automatic perfusion, and provides a water dispenser which is convenient to use and capable of being suitable for various water cups with indefinite volumes and the method for controlling automatic perfusion. An automatic perfusion control component of the water dispenser comprises a hot-water end electromagnetic valve which is connected with a hot-water outlet of a hot-water preparation device, a cold-water end electromagnetic valve which is arranged on a cold-water pipe in an engine base, a stepper motor, a lead screw, a slide block, an ultrasonic sensor which is used for detecting the height of a water cup, a fiber optic sensor for detecting a water level and an automatic perfusion controller, wherein after being connected in parallel, the water outlet end of the hot-water end electromagnetic valve and the water outlet end of the cold-water end electromagnetic valve are connected with a water outlet connection pipe; an output shaft of the stepper motor is provided with the lead screw; the lead screw is connected with the slide block through screw threads; the slide block is provided with the fiber optic sensor; the ultrasonic sensor is arranged in a water cup placement groove at the front end of the engine base; and the automatic perfusion controller is connected with the ultrasonic sensor, the fiber optic sensor, the stepper motor, the cold-water end electromagnetic valve and the hot-water end electromagnetic valve respectively.

Description

technical field [0001] The invention relates to the technical field of water dispensers, in particular to an automatic filling intelligent water dispenser and an automatic filling control method. Background technique [0002] Water dispenser is widely used because it can get cold / hot water for drinking in time. [0003] At present, water dispensers are mostly controlled manually. When taking water, the water receiving switch needs to be turned on manually, and then the water receiving switch needs to be turned off manually after the water is poured to a certain height. This mode of use is very inconvenient due to the need for the user to bend over and wait for the water to be filled in front of the water dispenser. Moreover, when hot water is taken, it is easy to cause injury to the person due to splashing of boiling water, and there is a potential safety hazard. For this reason, the intelligent control of water filling in drinking fountains has become a research direction ...

AI Technical Summary

Problems solved by technology

This type of water dispenser can only fill and fill water cups of a fixed size, and cannot automatically complete the task of fully filling water cups of various sizes and volumes, which limits its application.

Patent No. 2011202191217 discloses an automatic filling water dispenser in the patent literature titled "Intelligent Control Automatic Filling Water Dispenser", but due to its complex structure, it is difficult to implement
