Coffee Machines and Coffee Brewing Methods

Abstract

The invention discloses a coffee machine and a coffee brewing method. The coffee machine comprises a water tank; a brewing head is provided with a water outlet hole; It communicates with the water tank, the second water hole communicates with the brewing head, and the inside of the flow guide assembly is provided with a heating chamber and a regulating chamber between the first water hole and the second water hole, and the heating chamber communicates with the regulating chamber; the heating part ; The water pump assembly includes a helical blade and a driving part, the helical blade is connected to the output end of the driving part, and the helical blade is arranged in the regulating cavity. When brewing starts, the water in the brewing head and the regulating chamber can be sucked into the heating chamber through the water pump assembly, and then flow back after heating; or, the hot water in the heating chamber can be pumped to the regulating chamber to the brewing head for further brewing Preheating; or, control the water delivery through the pump water component to compensate for the fluctuation of water temperature caused by the change of water pressure. Through the above-mentioned technical means, large fluctuations in the brewing water temperature can be avoided, and the water temperature requirements for brewing coffee with various flavors can be met.

Description

technical field [0001] The invention is used in the field of coffee machines, and in particular relates to a coffee machine and a coffee brewing method. Background technique [0002] In the current coffee machines on the market, the water adding device of the coffee machine tends to leave a lot of excess water. When brewing starts, the water in the water adding device is heated and expands, which easily gushes out, resulting in a low initial brewing temperature, which seriously affects the coffee. Taste. In addition, at the later stage of brewing, due to the influence of the water level, the water pressure of the water adding device fluctuates greatly, and the temperature fluctuates greatly. Especially for coffee machines that require strong flavor functions, it is necessary to inject a certain amount of high-temperature coffee before the initial brewing. The amount of water is stewed to satisfy the coffee powder to be fully moistened by the appropriate water temperature. I...

[0002] In the current coffee machines on the market, the water adding device of the coffee machine tends to leave a lot of excess water. When brewing starts, the water in the water adding device is heated and expands, and it is easy to gushes out, resulting in a low initial brewing temperature, which seriously affects the coffee. Taste

In addition, at the later stage of brewing, due to the influence of the water level, the water pressure of the water adding device fluctuates greatly and the temperature fluctuates greatly. Especially for coffee machines that require strong flavor functions, it is necessary to inject a certain amount of high-temperature coffee before the initial brewing. The amount of water is stewed to satisfy the coffee powder to be fully moistened by the appropriate water temperature. It is difficult for existing coffee machines to meet the above temperature requirements.
