Description

Coffee machine simulating hand coffee making

Technical Field

The present invention relates to a coffee machine, and more particularly to a coffee machine simulating hand-brewing coffee.

Background

The drip-type brewing coffee used by a plurality of coffee houses in a workshop is characterized in that a filter respectively made of heat-resistant plastics, ceramics, metals and the like is utilized, the filter is placed on a cup or a collector, filter paper is sleeved in the filter, ground coffee bean powder is poured in, a person holds a brewing kettle with hot boiled water in the brewing kettle in bare hands, the hot boiled water in the brewing kettle is used for brewing coffee powder in bare hands from outer threads to inner threads along the central point of the coffee bean powder in the filter paper, the drip-type brewing coffee is a convenient, simple and sanitary method, but the hand of the person holding the brewing kettle with hot boiled water in bare hands can be kept in a calm and slowly-released mood to ensure that the angle and the positioning point of the hand can accord with the optimal conditions in the process of holding and inwards encircling by outer threads, so that the flow, the stability and the encircled diameter of the water outlet are controlled, the coffee bean powder and the hot water are fully mixed, four flavors and one fragrance in the coffee are extracted, and then the coffee is dripped out through the filter paper to filter fat, protein and bad impurities contained in the coffee, so that the coffee with fresh taste can be obtained, and the delicious coffee can be enjoyed while the health of the user is taken into consideration.

The infusion method of the drip-type infused coffee is mainly operated by manually holding an infusion pot with hot boiled water in the infusion pot. Therefore, the people who brew coffee must have more experience and the operation process is more ripe to determine the taste and flavor of the drip-type brewed coffee, if the people who brew coffee have insufficient experience and hold the brewing kettle with hot boiled water, the flow rate and stability of the water output of the brewing kettle are not good, the people who brew coffee can not be sure to be perfect after the coffee powder is brewed by the hot boiled water, so that the coffee is difficult to brew uniformly, the taste and fragrance of the coffee are affected, the quality of each cup of coffee brewed by the drip-type brewing kettle cannot be controlled, even when the guests in a coffee shop are numerous, the people can be stressed by the pressure of the coffee which must brew a plurality of cups quickly, the brewing process of the drip-type brewed coffee is reduced in busy hours, or the quality of the coffee is unstable due to the procedures of the flow rate and stability of the brewing kettle with hot boiled water held by hands of the people, to influence the pleasure and mood of the guests in the cafe to taste coffee.

The inventor of the present invention has solved the problem that the quality of brewed coffee is affected by the difficulty in controlling the flow and stability of the water discharged from a brewing kettle with hot water held by a bare hand, and the taste and mood of a guest in a cafe are lost. Therefore, the present inventor has previously obtained a coffee machine of taiwan patent publication No. M528138, please refer to fig. 1, in which a water supply unit a2, a transmission unit A3 and a water outlet unit a4 are disposed in a machine body a1 of the coffee machine a, wherein the transmission unit A3 is provided with a driving disk a31, the driving disk a31 is provided at an outer periphery thereof with a plurality of convex teeth a311 and a plurality of arc segments a312, and the convex teeth a311 and the arc segments a312 are disposed at equal intervals. When the water supply unit a2 heats cold water into hot water, and provides the hot water to the water outlet unit a4, and the transmission unit A3 drives one end of the water outlet unit a4 to be provided with a water outlet pipe a41, and the hot water is injected into the sections a51, a52 and a53 of the rotary drum a5 from the center to the outside in sequence, and the rotary drum a5 is matched to rotate, so that the hot water injected into the sections a51, a52 and a53 flows out from the corresponding through holes (not shown) in the sections a51, a52 and a53, the coffee powder brewing action of the hot water from the inner spiral to the outside can be simulated. However, when the convex teeth a311 and the arc segments a312 disposed on the outer periphery of the driving disk a31 respectively pass through a pushing block a42 disposed at an end of the water outlet unit A4 facing away from the water outlet pipe a41 and a convex column a421 at the front end of the pushing block a42, the water outlet pipe a41 disposed at an end of the water outlet unit A4 can only perform repeated actions of multiple water outflows and multiple retreats, which results in a poor simulated coffee making effect.
