Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the control circuit schematic diagram of the utility model embodiment.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the coffee machine in the present embodiment comprise boiler 1, boiler feed water device 2, the waterworks 3 that draw water, two-position three way magnetic valve 4, pouring and boiling device 5 and pressure valve 6.
The waterworks 3 that draw water are arranged on the outlet pipe place of boiler 1, and the water inlet of the waterworks 3 that draw water is connected with the outlet pipe of boiler 1, are provided with water feeding one-way valve 32 at the water inlet of the waterworks 3 that draw water, and the delivery port of the waterworks 3 that draw water is provided with out water one-way valve 33.The delivery port that goes out water one-way valve 33 is connected with the water inlet of two-position three way magnetic valve 4, and the first delivery port of two-position three way magnetic valve 4 is connected with the water inlet of pouring and boiling device 5, and the second delivery port of two-position three way magnetic valve 4 is connected with boiler 1 by water pipe.In addition, be provided with pressure valve 6 in the water side of pouring and boiling device 5, can be by changing or regulating this pressure valve 6 and realize brewing coffee under the different pressures state.
