The water inlet 5A is passed through the coffee hopper 1 and the water flows out from the water outlet 1A of the coffee hopper 1. At this time, the power is turned off to complete the cleaning operation of the brewer.

The second step: rotating the handle 19 to the vertical state, when the brewer is opened, as shown in FIG. 5, the coffee hopper 1 is taken out, and then the coffee powder (coffee bag, coffee capsule) is placed in the coffee hopper 1 The coffee hopper 1 is then safely pushed into the holder 7, and finally the handle 19 is rotated to a horizontal state, at which time the brewer is closed, as shown in FIG.

The third step: brewing coffee: turn on the power button, when the machine is warmed up, press the brewing coffee control button, the machine can cook the aromatic coffee.

Step 4: After brewing the coffee, press the brewing coffee control button to stop brewing the coffee, and rotate the handle 19 to the vertical state. At this time, the brewer is opened, as shown in Fig. 5, and then the coffee funnel 1 is taken from the bracket 7. Take out inside and finish brewing coffee.
