In another embodiment, the coffee extraction device includes a control for sensing the depression of the open / close button and calculating a coffee brewing amount, and a display for indicating the calculated coffee brewing amount.

The user presses the open / close button. The control unit detects the depression of the opening / closing button, operates the timer to calculate the time, and calculates the coffee extraction amount based on the steam generation amount. The control unit accumulates the coffee extraction amount over time to calculate the final coffee extraction amount. The display unit displays the calculated coffee extract amount on a scale. The display is displayed by increasing the scale according to the amount of coffee extracted. The user can see the amount of coffee by viewing the scale. The user determines the amount of coffee in the amount of the scales and decides whether to stop the coffee extraction.

When the user releases pressing the opening / closing button, the control unit initializes the amount of coffee, and the display unit stops displaying the amount of coffee. When the user presses the opening / closing button again, the control unit operates the timer to calculate the coffee extraction amount, and the display unit displays the increase amount according to the coffee extraction amount.

In another embodiment, the coffee extracting apparatus includes a pressure sensor for measuring the steam pressure, a control unit for calculating the coffee extraction amount when the steam pressure exceeds a certain pressure, and a display unit for displaying the calculated coffee extraction amount.

When the water containing housing is heated, steam is generated and when the generated steam is filled in the housing, the steam pressure rises and exceeds a certain pressure. The control unit calculates the coffee extract amount when the steam pressure exceeds a certain pressure. When the steam pressure becomes lower than a certain pressure, the control unit stops calculating the coffee extract amount. The display shows the calculated coffee extract.

In another embodiment, the coffee extracting device can correct the coffee extraction amount to the steam generation amount by measuring the steam pressure with the pressure sensor when sensing the depression of the opening / closing button and calculating the coffee extraction amount. Since the steam pressure varies with the degree of heating, the coffee extractor can estimate the amount of steam generated by measuring the steam pressure and calculate the coffee extract according to the changing steam pressure.
