Electromagnetic heating coffee machine and method for making coffee

Abstract

The invention discloses an electromagnetic heating coffee machine. The coffee machine comprises a water storing tank, a heating assembly, a coffee brewing core and a control circuit board for controlling the coffee machine to work, wherein the water storing tank, the heating assembly and the coffer brewing core are connected sequentially by a conveying pipe; the heating assembly comprises a boiler and an electromagnetic coil arranged under the bottom of the boiler, the boiler is a sealed boiler and provided with an inlet end and an outlet end, the inlet end and the outlet end of the boiler are in gas tight joint with the conveying pipe respectively, a water pump is arranged between the water storing tank and the boiler, and the water pump controls water flowing amount of the boiler. The electromagnetic heating method is adopted for the coffee machine, the energy efficiency is high, the pre-heating time is short, hot water can be conveyed out instantly and used for brewing coffee, a heating system does not need heating wires, and the service life is greatly prolonged. Besides, the electromagnetic heating coffee machine has the functions of making the coffee and generating steam to churn milk bubbles. The invention further discloses a method for making the coffee with the milk bubbles.

Description

technical field [0001] The invention relates to a coffee machine, in particular to an electromagnetic heating coffee machine. The invention also relates to a method of making coffee. Background technique [0002] Most of the heating elements used in existing coffee machines are aluminum die-cast heating elements, which contain heating wires and water pipes. Contact heat, while the heating wire transmits heat through itself to the die-casting body, and then the die-casting body transfers to the water pipe, so that the water is heated. Although the heating method of aluminum die-casting heating element is simple to manufacture, the energy efficiency is average due to too many heat transfer media, and because the aluminum die-casting body itself needs to absorb heat, it needs a long warm-up time to make the aluminum die-casting heating element Entering the normal working state is time-consuming and energy-consuming, and the user experience is poor. Furthermore, because the h...
