Description

Technical Field

[0001] The present invention relates to the technical field of cup washing machines, and in particular to a novel cup washing machine with ozone disinfection, independent nozzle control and an external slide rail structure. Background Art

[0002] A cup washer is a device used to automatically wash cups. As a commercial and household device, the demand for cup washers has grown rapidly in recent years, especially in catering, hotels and home scenarios. With technological advances, cup washers have been continuously improved in terms of cleaning efficiency, energy saving, environmental protection and intelligence. However, there are still the following disadvantages: 1. The cup holder of the cup washer generally adopts a drawer-type switch design, and the cup holder is installed in the cabinet using a slide rail to ensure flexible switching. However, since the slide rail is often exposed to water vapor, it is easy to rust, resulting in a decrease in its service life; 2. The existing cup washer cannot independently control a single nozzle. Even if there is no cup placed on part of the cup holder, the nozzle will be turned on, which causes unnecessary waste of water resources; 3. The existing cup washers have a variety of cleaning methods, mainly including ultrasonic cleaning, high-pressure spraying, steam cleaning and chemical cleaning, but ultrasonic cleaning has high energy consumption and high noise, high-pressure spraying can easily damage thin-walled cups and consumes more water, steam cleaning takes a long time, and the equipment cost is high, and chemical cleaning requires regular replacement of cleaning agents, and chemical substances may remain. Summary of the invention

[0005] The ozone generated by the ozone generator is mixed with the washing water flow through the venturi tube. When the washing pump is running, the venturi tube uses the negative pressure of the water flow to actively inhale ozone, achieving full mixing of gas and liquid, and the ozone dissolution rate is ≥90%. The mixed ozone water is sprayed out through the nozzle in atomization, without chemical residue, and the sterilization rate is as high as 99.9% (refer to GB 4789.2-2016 standard).

[0014] The drainage pump is installed in the bottom sink. The drainage pipe is made of UPVC material, with an inner diameter of 50mm and an inclination angle of 5° to ensure rapid discharge of wastewater.

[0015] The controller supports Wi-Fi communication module to achieve remote control and status monitoring.

[0016] The touch screen (resolution 800×480) is integrated into the panel, and the interface is divided into three modules: "Automatic Mode", "Manual Mode" and "Ozone Concentration Setting". In automatic mode, the controller dynamically turns on and off the nozzle according to the sensor signal; in manual mode, the user can select the nozzle switch area through the 4×4 matrix button.

[0017] The controller integrates a Wi-Fi module (model ESP32-C3, supporting IEEE 802.11b / g / n protocols), and users can remotely start / pause cleaning, view water consumption and ozone concentration through a mobile phone APP. In automatic mode, an infrared sensor (model E18-D80NK, detection distance 10-30cm, response time ≤0.1 second) monitors the position of the cup in the cup holder in real time and dynamically adjusts the switch of the nozzle (24); in manual mode, users can customize the nozzle working area through the touch screen (resolution 800×480).
