Coffee machine

Abstract

The invention provides a coffee machine. A water vapor preparation system uses steam for driving a stirring system and / or conveys the steam or hot-state water to a brewing system; the stirring system stirs foaming liquid for foaming the foaming liquid through being driven by the steam; a foaming heating system receives the steam after the steam driving of the stirring system by a water vapor preparation system or the hot-state water condensed by the steam, and heats the foaming liquid stirred in the stirring system; a fermentation system receives the steam or the hot-state water conveyed by the water vapor preparation system to ferment or soak coffee powder in the fermentation system so as to prepare coffee; and a control system is in signal connection with and controls one kind or several kinds of systems of the water vapor preparation system, the stirring system, the foaming heating system and the brewing system. The coffee machine has the advantages that the steam can be used for stirring foaming and heating at the same time; through the stirring foaming, the foaming quantity of the foaming liquid can be great; the foam is sufficient, fine and dense; the driving of the stirring system by a motor is not needed; the device cost is low; and the operation energy consumption is low.

Description

technical field [0001] The invention relates to the field of beverage preparation equipment, in particular to a coffee machine. Background technique [0002] At present, there are two technologies for automatically foaming liquid and synchronously heating the foaming liquid on the coffee machine: the first technology is to use steam to foam and heat the foaming liquid through the Venturi tube. This device has a simple structure and low cost. But the shortcomings are also very obvious, mainly reflected in the insufficient foam, not dense, easy to dissipate, the temperature of the foaming liquid is difficult to control, and it is not suitable for foaming a large amount of foaming liquid; the second technology is to use the motor to drive the stirring shaft. Foaming liquid and using an additional heating element to heat the foaming liquid at the same time, this device has a good foaming effect, but due to the need for an additional motor, heating element, and control system S4,...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to solve the problems of insufficient foam, not dense, easy to dissipate, difficult to control the temperature, and not suitable for foaming a large amount of foaming liquid when the foaming liquid is heated by steam through the Venturi tube, and through mechanical stirring. The problem of high cost and high energy consumption when the heating element heats the foaming liquid provides a coffee
