[0024] The first heater 13 is a water storage type large capacity boiler, which is a hot water boiler, and the second heater 15 is a water storage type small capacity boiler, which is a coffee boiler.

[0025] Through the above water system, the following functions are achieved:

[0026] After passing through the water inlet solenoid valve 2, the municipal external water or water tank water 1 is divided into two paths to replenish the hot water boiler 13 and the coffee boiler 15 at the same time.

[0027] When the hot water boiler 13 is replenished with water, the external water or water tank water 1 passes through the water inlet solenoid valve 2, the hot water pump 3, the hot water flow meter 4, the hot water check valve 5, the hot water boiler water replenishment solenoid valve 9, the hot water boiler 13, the bypass hot water solenoid valve 18, and the beverage outlet 26 in sequence. The water replenishment action is that the water inlet solenoid valve 2, the hot water boiler water replenishment solenoid valve 9 and the bypass hot water solenoid valve 18 are opened, and the hot water pump 3 is powered on to work.

[0028] When the coffee boiler 15 is replenished with water, the municipal external water or the water tank water 1 passes through the water inlet solenoid valve 2, the coffee water pump 6, the coffee flow meter 7, the coffee one-way valve 8, the coffee boiler water replenishment solenoid valve 11, the coffee boiler 15, the coffee boiler pressure relief solenoid valve 19, and the water storage tray 22 in sequence. The water replenishment action is that the water inlet solenoid valve 2, the coffee boiler water replenishment solenoid valve 11 and the coffee boiler pressure relief solenoid valve 19 are opened, and the coffee water pump 6 is powered on to work.

[0029] The two water replenishment actions are performed simultaneously. When the respective water level probes detect the water level, the respective water pumps are stopped. Finally, when both water pumps stop working, the water replenishment action is completed.

[0030] 2. Making Italian coffee:

[0031] After passing through the water inlet solenoid valve 2, the municipal external water or water tank water 1 flows through the coffee water pump 6, the coffee flow meter 7, the coffee one-way valve 8, the coffee boiler water supply solenoid valve 11, the coffee boiler 15, the coffee pressure relief solenoid valve 20, the brewer 23, the coffee outlet solenoid valve 24, and the beverage outlet 26 in sequence;

[0032] During the production process, the water inlet solenoid valve 2, the coffee boiler water replenishment solenoid valve 11, the coffee pressure relief solenoid valve 20 and the coffee outlet solenoid valve 24 are opened, and the remaining solenoid valves are closed. At this time, the coffee water pump 6 is powered on and starts to extract coffee. The coffee flows out from the beverage outlet 26 through the coffee outlet solenoid valve 24. When the extraction is completed, all valves are closed, and the pressure in the brewer 23 flows into the water storage tray 22 through the coffee pressure relief solenoid valve 20. The residual coffee in the rear end pipeline of the brewer 23 flows into the water storage tray 22 through the coffee outlet solenoid valve 24.

[0033] 3. Make classic American coffee:

[0034] It is divided into two production lines, coffee and hot water. The two lines can be produced successively, the order of which can be adjusted, and they can also be produced simultaneously.

[0035] First, the extraction method of espresso is the same as that of making espresso.

[0036] In the second route, water flows through municipal external water or water tank water 1, water inlet solenoid valve 2, hot water pump 3, hot water flow meter 4, hot water check valve 5, hot water boiler water supply solenoid valve 9, hot water boiler 13, bypass hot water solenoid valve 18, and finally converges with the outlet of coffee outlet solenoid valve 24 to flow out at beverage outlet 26. During the production process, the water inlet solenoid valve 2 is opened, the hot water boiler water supply solenoid valve 9 and the bypass hot water solenoid valve 18 are opened, and the hot water pump 3 is powered on to provide bypass hot water.

[0037] After production is completed, close all pump valves.

[0038] 4. Make hot water:

[0039] The water flows through the municipal external water or water tank water 1, the water inlet solenoid valve 2, the hot water pump 3, the hot water flow meter 4, the hot water check valve 5, the hot water boiler 13, the hot water rod solenoid valve 17, and finally flows out from the hot water rod 25.

[0040] 5. Boiler emptying:

[0041] The water in the hot water boiler 13 passes through the hot water boiler water replenishment solenoid valve 9 and the ice coffee solenoid valve 10, and finally flows out through the beverage outlet 26; the hot water in the coffee boiler 15 flows through the coffee boiler pressure relief solenoid valve 11 and the boiler emptying solenoid valve 12, and finally flows into the water storage pan 22; the boiler emptying is carried out in sequence. When the hot water boiler 13 is emptied, only the hot water boiler water replenishment solenoid valve 9 and the ice coffee solenoid valve 10 are opened, and then the hot water boiler 13 is heated until part of the hot water is converted into steam, and the hot water in the boiler is squeezed out to the beverage outlet 26 to flow out. After the hot water boiler 13 is completed, all solenoid valves are closed, and then the coffee boiler 15 is emptied, and the coffee boiler pressure relief solenoid valve 11 and the boiler emptying solenoid valve 12 are opened. Similarly, the coffee boiler 15 is heated, and part of the hot water is heated to steam to squeeze the hot water in the boiler to the water storage pan 22 to flow out. After completion, all solenoid valves are closed, and the boiler is emptied at this time.

[0042] Through the above functions, the following advantages are achieved:

[0043] 1. Multiple solenoid valves work together to make a variety of drink combinations;

[0044] 2. Solenoid valve control, stable and efficient;

[0045] 3. Double water pumps and double heating, working together with the solenoid valve, can make hot water and cold water at the same time as making coffee;

[0046] 4. The safety valve can ensure that the water channel plays a protective role when the pressure is too high;

[0047] 5. It solves the problems of low efficiency in making large cups of American coffee and cleaning and maintenance of coffee machines, bringing new opportunities and challenges to the future development of the coffee market.

[0048] To sum up, the water system of a coffee beverage equipment pointed out in the utility model, on the one hand, has a rich variety of beverages and efficient production. In addition to general espresso, American coffee, etc., it can also provide bypass American coffee and iced coffee functions; on the other hand, it has an automatic cleaning function, which can efficiently and conveniently clean the brewer and pipelines to ensure cleanliness and hygiene. Automatic cleaning does not require manual intervention, which greatly saves labor costs.
