Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a digitally controlled coffee machine. Background Art

[0002] With the rapid development of the global economy and the increasing frequency of cultural exchanges, coffee culture has spread widely around the world, and coffee has become one of the most popular drinks. As the coffee market continues to expand, consumers' pursuit of coffee quality has reached an unprecedented level. They not only require coffee to have a mellow and rich taste and rich and diverse flavors, but also have higher requirements for the coffee making process, hoping to obtain a more convenient, efficient and fun making experience.

[0003] Looking back at the traditional way of making coffee, hand-grinding coffee beans and manual brewing dominated. Hand-grinding coffee beans relies on manual operation, and there are significant differences in the strength and grinding rhythm of different people, which makes it difficult to unify the coarseness of the ground coffee powder. The coarseness of the coffee powder is directly related to the extraction effect when brewing coffee. Too coarse coffee powder may lead to insufficient extraction and a light coffee taste; too fine coffee powder may cause over-extraction, making the coffee bitter.

[0004] The manual brewing process also faces many challenges. The temperature of hot water is crucial to the flavor extraction of coffee. Too high a temperature will destroy the aroma components in the coffee, and too low a temperature will not fully stimulate the flavor of the coffee. However, in the manual brewing process, it is difficult to accurately control the hot water temperature within the optimal range. In addition, the brewing time and the ratio of coffee powder to water depend on the personal experience of the brewer and lack scientific and precise measurement, which makes it difficult to ensure the stability and consistency of the quality of each cup of coffee. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and provide a digitally controlled coffee machine.

Detailed Description of the Invention

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] A numerical control coffee machine according to a preferred embodiment of the present invention will be described in detail below.

[0040] Embodiment 1, as Figures 1-10 shown, a numerical control coffee machine includes a body 1, and the body 1 includes five mechanisms and one unit:

[0041] A coffee grinding mechanism 2 for grinding coffee beans into coffee powder is provided on the back of the machine body 1. The coffee grinding mechanism 2 includes a first motor 21, grinding cutters, and a coffee bean storage bin 22. The first motor 21 is drivingly connected to the grinding cutters. The coffee bean storage bin 22 is arranged above the grinding cutters, and a discharge port 221 is provided at the bottom of the coffee bean storage bin 22;

[0042] A quantitative powder feeding mechanism 3 for quantitatively conveying the ground coffee powder to the brewing chamber is connected below the coffee grinding mechanism 2;

The heated hot water flows into the brewing chamber through the water outlet 411. In the brewing chamber of the brewing mechanism 5, the coffee powder is fully mixed with the hot water to complete the coffee brewing process. During the whole process, the numerical control unit 6 plays a key control role. It is electrically connected to the coffee grinding mechanism 2, the quantitative powder feeding mechanism 3, the hot water supply mechanism 4, and the brewing mechanism 5, and the working states of each mechanism are displayed in real time through the display screen 61. Users can adjust the working parameters of each mechanism according to their taste preferences, such as adjusting the rotation speed of the first motor 21 to control the grinding fineness of the coffee powder, and setting the working frequency of the electromagnetic pump 44 to adjust the flow rate and velocity of the hot water, so as to achieve precise control of the coffee brewing effect.
