Coffee maker

Abstract

The invention discloses a coffee maker, which comprises a main machine, a coffee cup and a processing hopper capable of smashing or stirring a coffee raw material and filtering coffee liquid, wherein a first water inlet is formed in the main machine; the processing hopper comprises an inner hopper body and an outer hopper body which are used for accommodating the coffee raw material, a lateral wall of the inner hopper serves as a filter screen, and a first water outlet is formed in the outer hopper; when the processing hopper is installed on the main machine, the inner hopper body is in sleeve fit in the outer hopper body, a first accommodating cavity communicated with the first water outlet is formed between the inner hopper body and the outer hopper body, the first water inlet is communicated with the inner cavity of the inner hopper body, and the first water outlet can be communicated with the inner part of the coffee cup, and an area between the inner hopper body and the main machine and an area between an opening of the inner hopper body and an opening of the outer hopper body are both sealed. According to the coffee maker disclosed by the invention, the whole structure of newly improved to introduce a micropressure principle into the coffee maker; thus, not only can a coffee extracting rate and coffee drink purity be improved based on effectively shortening coffee making time, but also self making cost of coffee is low.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a coffee machine. Background technique [0002] Coffee is one of the most popular drinks in the world. It can bring pleasure and excitement to people. With the continuous improvement of people's living standards, there is an increasing pursuit of homemade coffee and coffee taste. A coffee machine is a general term for a coffee brewing machine, and it is the best choice for people to make their own coffee drinks. Today, the coffee machines active in the market are mainly drip coffee machines and capsule coffee machines. [0003] However, for the drip coffee machine, there are many defects because it needs to vent holes above the coffee bucket for holding coffee powder so that it can work in a pressure-free state, such as: [0004] (1) The heat is easily lost, resulting in a low extraction rate of coffee powder (only about 18%) and a low brewing concentra...

AI Technical Summary

Problems solved by technology

[0004] (1) The heat is easily lost, resulting in a low extraction rate of coffee powder (only about 18%) and a low brewing concentration;

[0005] (2) Only rely on the gravity of the coffee powder itself to filter, then, if the filter mesh is designed too densely, it will be difficult to drip and brew, which prolongs the production time of coffee drinks; otherwise, if the filter mesh is designed too sparsely (such as The filter mesh of the current drip coffee machine can only be set to 80-100 mesh at most), and the brewed coffee contains more dregs, which greatly affects the taste

[0006] For the capsule coffee machine, although it solves the above-mentioned technical problems of the drip coffee machine to a certain extent, that is, it can increase the extraction rate of the coffee powder and the purity of the coffee, and the brewing efficiency is also improved, but because of Only special coffee capsules can be used, so the cost of self-made coffee drinks is relatively high. In addition, the structure of the capsule coffee machine is also relatively complicated, and the product manufacturing cost is also high
