This is actually very simple. Open the top cover and divide it into two parts. The rear part is the water inlet of the water tank, and the front part is a circular extraction bin for storing powder. Under the extraction bin, there is a coffee pot and a heating plate. When in use, a proper amount of drinking water is added into the water tank, the powder filter basket is taken out from the filter bin, the ground coffee powder is put into the basket, the filter basket is put back into the filter bin, the top cover is closed, and the coffee pot is inserted under the heating plate, so that the water leakage port is aligned with the leak-proof valve at the bottom of the filter bin. Press the switch to start heating. When the water is heated, the hot water is pumped to the top spray port by the water pump and injected into the filter bin to extract the coffee liquid. When the water tank is emptied, the water pump automatically stops working, and the heating plate continues to keep warm and heat, during which the water pump no longer works. After drinking coffee, turn off the power switch, open the top cover to take out the filter basket and filter rack, pour out the residual powder, rinse the powder basket with clear water, and hold the leak-proof valve at the bottom of the filter rack with your fingers. When flushing, the leak-proof valve at the bottom must flow out a lot of clear water. After washing, put it in a dry place to dry the coffee powder basket and filter rack, lift the top cover of the coffee pot, rinse it with clear water or gently scrub the inner wall and the pot body with soft cotton cloth, put it in a dry place to dry, wipe the heating plate with semi-wet cotton cloth, and put all the utensils into the main machine in order after drying, waiting for the next use.
