Description

Waterway system suitable for movable water tank and with disinfection function

Technical Field

The utility model relates to the technical field of household appliance waterway systems, in particular to a waterway system with a disinfection function suitable for a movable water tank.

Background

The liquid level sensor is one of the sensors commonly used in the household electrical appliance industry, and is mainly applied to household electrical appliances with waterway systems, such as washing machines, water dispensers, coffee machines, water purifiers, dish washers, water heaters, humidifiers and the like. The liquid level sensor is divided into photoelectric type, capacitance type, floating ball type, electrode type and pressure type liquid level sensor according to the use types, wherein the photoelectric type, capacitance type, floating ball type and electrode type liquid level sensor is mainly used as a liquid level switch, and outputs a signal when the liquid level reaches a certain height, so that the real-time height in the liquid level lifting process can not be monitored. The pressure type liquid level sensor is communicated with the bottom of the container generally through a sealed air pipe, the pressure generated by liquid on the bottom of the container is converted into the pressure of gas in the sealed air pipe, and the pressure type liquid level sensor monitors the liquid level in the container in real time by monitoring the pressure change of the gas.

In order to realize liquid level monitoring in the prior art, a Hall rotor water flow mode is adopted. The water flow meter is arranged on a pipeline connected with the water heating equipment, water flow in the pipeline pushes the water flow meter to rotate to generate pulses in the water pumping process, and the singlechip system of the electric appliance converts the water flow through pulse counting in unit time, so that the water outlet volume is obtained. The waterway system adopting the Hall rotor water flowmeter can only measure the relative liquid volume in the pumping process by a pulse counting mode, so that the liquid level of the water tank can not be monitored in real time, and the liquid level monitoring function of the water tank can not be realized. Moreover, the pulse counting method is easy to generate accumulated errors, and the accuracy of measurement is affected.

The pressure type liquid level sensor can monitor the liquid level of the water tank in real time, but after long-term use, water enters the sealed air pipe, so that the initial zero point of the liquid level calibration is inaccurate, and because of the difference of air pipe assembly of the household appliance, the water quantity entering the air pipe also has individual difference, so that the zero point is difficult to recalibrate in the use process of the electric appliance, the actual measurement precision of the liquid level is low, and the consistency is poor.

In addition, the interior space of the small household appliance is limited, the general structure is compact, the space is not provided with a residual water cleaning structure, residual water remained in the waterway system cannot be discharged, bacteria breeding and deterioration are easy to occur when the water dispenser is not used for a long time, and the health of a user can be influenced.

In summary, there is a need in the art for a waterway system that monitors tank level in real time using a pressure type level sensor and can solve the problems of bacteria and spoilage of the remaining water in the waterway system.
