[0022] The utility model will be further described below in combination with the drawings and examples.
[0023] Referring to Figures 1-6 The pipeline system of the coffee machine comprises a water pump 1, a coffee boiler 2, a steam boiler 3, an instant heater 4, and a first electromagnetic valve 5. The input end 6 of the instant heater 4 is connected to the water pump 1. The first output end 7 of the instant heater 4 is connected to the first water inlet 8 of the coffee boiler 2. The second output end 9 of the instant heater 4 is connected to the steam inlet 10 of the steam boiler 3 through the first electromagnetic valve 5 to control the steam entering the steam boiler 3. The instant heater 4 is an instant heating tube.
[0024] The coffee boiler 2 is provided with a water outlet 12, a second water inlet 13, and a water outlet mechanism. The first water inlet 8, the heating cavity 25 of the coffee boiler 2, and the water outlet 12 are sequentially connected. The water outlet 12 is connected to the second water inlet 13 through the second electromagnetic valve 11 to control the water flowing out of the heating cavity 25. The second water inlet 13 is connected to the water outlet mechanism.
[0025] Through the control of the first electromagnetic valve 5 and the second electromagnetic valve 11, the instant heater 4 can provide preheated water for the coffee boiler 2 or high-temperature steam for the steam boiler 3.
[0026] The coffee machine further comprises a third electromagnetic valve 14 and a steam pipe 15. The steam outlet 16 of the steam boiler 3 is connected to the steam pipe 15 through the third electromagnetic valve 14 to control the steam output to the steam pipe 15.
[0027] The water outlet mechanism comprises a water guide pipe 17, a liquid outlet nozzle 18, and a filter screen 19. The water guide pipe 17 is located in the heating cavity 25. The upper end of the water guide pipe 17 is connected to the second water inlet 13, and the lower end is connected to the liquid outlet nozzle 18. The liquid outlet nozzle 18 is connected to the filter screen 19, and the filter screen 19 is located below the liquid outlet nozzle 18.
[0028] When making coffee, the water pump 1 supplies water to the instant heater 4. The instant heater 4 preheats the water to 80-110 degrees. The preheated water is input to the coffee boiler 2. The coffee boiler 2 heats the water through the first heating component 24 to stabilize the water temperature. After the water temperature is stabilized, the water enters the water guide pipe 17 from the second water inlet 13 through the second electromagnetic valve 11, then reaches the liquid outlet nozzle 18, and is sprayed onto the filter screen 19 through the liquid outlet nozzle 18. The hot water after entering the filter screen 19 is mixed with the coffee powder. This structure can stabilize the coffee temperature and prolong the continuous working time.
[0029] When making steam, the water pump 1 supplies water to the instant heater 4. The instant heater 4 preheats the water to 110-135 degrees. The vaporized water steam enters the steam boiler 3 through the first electromagnetic valve 5. The steam boiler 3 simultaneously heats the stored water in the boiler body through the second heating component 21 to generate steam. The steam is output to the steam pipe 15 through the third electromagnetic valve 14, which can make the steam output for a long time without weakening.
[0030] When the steam pot 3 is short of water, or the steam pot 3 is refilled with water for the first time, the water pump 1 supplies water to the instant heater 4, the instant heater 4 preheats the water to 70-100 degrees, and the heated water enters the steam pot 3 in turn through the first electromagnetic valve 5 and the steam inlet 10. When the water level reaches the position of the water level probe 27, the water pump 1 stops working, and the second heating component 21 further heats the water in the pot body to reach the set temperature. This method can avoid the problem that the traditional steam pot needs to wait for the water level to reach the specified position before heating in order to avoid burning the heating tube. The preheating time of the steam pot 3 can be shortened, and the problem of performance degradation of the steam pot 3 caused by refilling cold water in the middle of the process can be avoided.
[0031] When coffee and steam need to be made at the same time, the instant heater 4 only supplies water to the coffee pot 2, the first electromagnetic valve 5 is not opened, and the second electromagnetic valve 11 and the third electromagnetic valve 14 are opened. At this time, the generation of steam can only be through the second heating component 21 of the steam pot 3 and the steam stored in the steam pot 3 itself, and the performance of simultaneous output of coffee and steam can be maintained for a short time.
[0032] The instant heater 4 is provided with a thick film type heating body.
[0033] The heating cavity 25 is provided with a first heating component 24 for heating the water in the heating cavity 25. The first heating component 24 is a heating tube.
[0034] The water outlet 12 is arranged on the side of the heating cavity 25. The side of the heating cavity 25 is provided with a first temperature sensor 20 for detecting the water temperature of the water outlet 12. The first temperature sensor 20 is arranged close to the water outlet 12, so that the detected water temperature is more accurate. By detecting the water temperature, the working state of the first heating component 24 and the water temperature of the heating cavity 25 are further regulated.
[0035] The steam pot 3 is provided with a second heating component 21 for heating the water in the steam pot 3 and generating steam. The second heating component 21 is a heating tube.
[0036] The steam outlet 16 is arranged on the top of the steam pot 3. The top of the steam pot 3 is provided with a second temperature sensor 22 for detecting the steam temperature of the steam outlet 16. The second temperature sensor 22 is arranged close to the steam outlet 16, so that the detected steam temperature is more accurate. By detecting the steam temperature, the working state of the second heating component 21 is further regulated.
[0037] The third temperature sensor 23 is arranged on the instant heater 4, is arranged close to the first output end 7 and the second output end 9, and is used for detecting the outlet water temperature of the first output end 7 and the second output end 9.
[0038] The steam pot 3 is provided with a drain port 26 at the bottom, which is used for draining water in the steam pot 3.
[0039] The steam pot 3 is provided with a water level probe 27 at the top, which is used for detecting the water level height of the pot body.
