Water dispenser provided with vacuum generator

Abstract

A water dispenser provided with a vacuum generator comprises a main water dispenser body, the vacuum generator and a balance box, wherein a water inlet, a room-temperature water outlet and a hot wateroutlet are formed in the main water dispenser body; a control panel, a first control valve, a second control valve and a thermal liner are arranged in the main water dispenser body; a water inlet endof the first control valve is communicated with the water inlet, a water outlet end of the first control valve is communicated with an inlet of the thermal liner, an outlet of the thermal liner is communicated with the hot water outlet, a water inlet end of the second control valve is communicated with the water inlet, and a water outlet end of the second control valve is communicated with the room-temperature water outlet; a positive pressure port, a negative pressure port and a pressure adjusting port are formed in the vacuum generator, the positive pressure port is communicated with the first control valve, the negative pressure port is communicated with the thermal liner, the pressure adjusting port is communicated with a lower outlet of the balance box, and an upper outlet of the balance box is communicated with the outside. A water supply structure adopting the vacuum generator replaces the conventional water pump based water supply structure, noise is reduced greatly during use, the water dispenser is safer and more energy-saving, maintenance is not needed, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of water dispensers, in particular to a water dispenser with a vacuum generator. Background technique [0002] A water dispenser is a device that heats up or cools down barreled pure water (or mineral water) and makes it convenient for people to drink. Put bottled water above the machine and use it together with bottled water. The most common drinking water machine is placed above the bottled water, and it is used in conjunction with the bottled water. This water dispenser is designed as a special connector on the top of the fuselage to place the bucket upside down. The latest foreign water dispenser puts the bottled water in the machine The lower part is sucked by the water pump, which is safer and more hygienic than conventional water dispensers. However, there are also some defects in the water dispenser using the lower bucket of the water pump. For example, the water pump will generate a lot of noise, the servic...

AI Technical Summary

Problems solved by technology

However, there are also some defects in the water dispenser using the lower bucket of the water pump. For example, the water pump will generate a lot of noise when it is working, the service life of the water pump is limited, and the cost is relatively high, etc.
