Method for water level detection of water purification tank and system

Abstract

The invention provides a method for water level detection of a water purification tank. The method is used for solving the problem in the prior art that the running time is prolonged and the working efficiency of the water purification tank is lowered due to the fact that the water level detection of the water purification tank is not in place. The method comprises the steps: S1: receiving a start-up signal of the water purification tank, and detecting whether a water level of the water purification tank is at a preset 0 water level or not; S2: if the condition that the water level of the water purification tank is at the preset 0 water level is detected, performing preset water intake action, and judging whether the preset water intake action is completed or not; if the condition that thewater level of the water purification tank is not at the preset 0 water level is detected, performing preset drainage action, and judging whether the preset drainage action is completed or not; S3: if the preset water intake action is not completed, issuing an abnormal water intake alarm; if the preset drainage action is not completed, issuing an abnormal drainage alarm. By adopting the method, water in the water purification tank can work according to a preset water level, and thus, the aims of protecting an ultrasonic assembly in the water purification tank and saving energy are achieved.

Description

technical field [0001] The invention relates to the technical field of purification water tank control, in particular to a method and system for detecting the water level of a purification water tank. Background technique [0002] With people's requirements for the quality of life, the requirements for kitchen utensils are also getting higher and higher. For example, the current purification sink can realize the functions of purification, air blowing and ultrasound, which improves the quality of people's life. However, the current purification sink is also There are a series of problems. [0003] For example, in the current purified water tank, when starting up, regardless of whether there is water in the washing chamber, the purified water tank will perform drainage operation within a certain period of time, thereby increasing the running time of the purified water tank. After the purified water tank completes the predetermined water intake procedure, the purified water ta...

AI Technical Summary

Problems solved by technology

After the purified water tank completes the predetermined water intake procedure, the purified water tank will start cleaning operations such as purification, air blowing, and ultrasonic cleaning without judging whether there is water in the machine. If there is no water in the machine due to water leakage at this time, ultrasonic It will run in an anhydrous state, which will cause heat damage to the ultrasonic components, thereby affecting the sealing effect and causing water leakage

If the water in the purified water tank is still at a high level at the end of the drainage time, it indicates that the purified water tank has an abnormal drainage failure, but the purified water tank cannot determine whether the drainage is abnormal during the drainage process
