Description
Technical field
The present invention relates to coffee machine field, particularly relate to the coffee machine of the predeterminable control of a kind of quantity of coffee.
Background technology
At present along with the raising that quality of coffee is required by human consumer, has there is various tastes in the same a capsule of most of coffee business, and few person three or five kinds, many persons tens kinds. In addition, along with coffee capsule profile is tending towards stdn gradually, the coffee capsule profile of multiple coffee business similar (such as imitative nest) occurs, can use on a machine simultaneously. Visible, same coffee machine need to meet the capsule of various tastes, many coffee business, due to its production technique, the baked coffee degree of depth, proportioning difference, its best coffee extracted amount required is also different, therefore, human consumer in use needs repeatedly to be preset by quantity of coffee, sometimes also can carry out repeating within multiple time period arranging, operate very loaded down with trivial details.
The mode of existing coffee machine default control quantity of coffee has three kinds: (1) coordinates the manipulation part of multiple button by PCB computer board program, the corresponding default quantity of coffee of each button, during use, it may also be useful to person by selecting different buttons select corresponding different quantity of coffee. In this mode, need to take bigger space due to multiple button, make the needs in functional structure and profile, aesthetically produce to conflict, therefore it is difficult to accomplish that many quantity of coffee are preset in actual applications, existing market adopts the coffee machine of which generally also only have 2��3 default quantity of coffee (namely needing 2��3 buttons to control). (2) control quantity of coffee by the mode of timer, namely machine is equipped with a timer, control quantity of coffee by control time length of making coffee. In this mode, manually going owing to all needing user every time to regulate timer, therefore affect by the factor such as speed, angle deviation of adjustment, be difficult in operation precisely preset, quantity of coffee deviation is bigger. (3) by controlling quantity of coffee by compressing switch manually, namely when quantity of coffee reach user expection require time, manual off switch, controls quantity of coffee with this. This kind of mode cost is lower, but quantity of coffee control is accurate not, operates simultaneously and relatively bothers, needs people to keep by machine after unlatching, in fact adopts the coffee machine of this mode also can think and Non-precondition value controls completely by manual operation.
