Description

Technical Field

[0001] The invention relates to a coffee machine and a brewing mechanism thereof, which is a multifunctional coffee machine. Background Art

[0002] A coffee machine is an electrical device used for making coffee. It is generally divided into semi-automatic and fully automatic types. Semi-automatic coffee machines rely on manual operation for grinding, pressing, loading, brewing, and manual removal of residues. Fully automatic coffee machines are coffee machines that automatically control the entire process of brewing coffee, including preheating, cleaning, grinding, pressing, brewing, and draining. Coffee is brewed according to scientific data and procedures, and coffee can be obtained with just a light press. However, with the improvement of people's quality of life and the popularization of coffee culture, the functional requirements for coffee machines are becoming increasingly diversified and demanding. Traditional coffee machines often have a single function and can only meet the needs of drip brewing coffee or can only use specific types of coffee capsules, etc., and cannot meet consumers' needs for different coffee making methods in different scenarios. For example, the production process of a drip coffee machine is relatively simple, but the coffee flavor may be relatively single; although the capsule coffee machine is convenient, the capsule types are limited and the cost is high; the extraction coffee machine can make a richer coffee, but the operation is relatively complicated; and for consumers who like milk coffee such as cappuccino and latte, additional equipment is needed to make milk foam. The main brands of coffee capsules are: Nespresso from Nestle, TASSIMO and K-cup from JDE Zhenyin, Oro (Ovo), Lavazza, Monodor, ecaffe from Gaggia from Italy, and Allcream from Hanpai. Therefore, the market urgently needs a coffee machine that integrates multiple functions to improve the user experience and convenience. For example, the application number 202320768185.5 disclosed in the Chinese patent document, the authorization announcement date is 2023.06.23, and the utility model name is "a coffee machine"; for example, the application number 202222338445.3 disclosed in the Chinese patent document, the authorization announcement date is 2023.03.03, and the utility model name is "a dual-purpose coffee machine and top cover assembly"; but the above-mentioned coffee machine and similar products are mainly drip coffee machines, which are difficult to use as capsule coffee machines, especially difficult to use with coffee capsules such as K-cup capsule coffee at the same time.

[0037] The American drip function module of this coffee machine includes a detachable drip pot, a metal filter basket, and a coffee basket; the drip pot is made of transparent glass, which is convenient for users to observe the water level and the coffee brewing process. At the same time, a coffee basket is set in the brewing component above the drip pot to place the filter basket and coffee powder; the filter is finely designed to effectively filter the coffee grounds, and the brewing component cover above the brewing component is distributed like a shower hole, so that the coffee in the filter basket is brewed evenly, ensuring that the dripped coffee tastes pure. There is a water stopper structure at the bottom of the brewing component above this position. Only when the drip pot is in place, the water outlet will be connected; otherwise, it will be sealed by umbrella-shaped silicone.

[0038] When the coffee machine is in the American drip function module state, hot water enters from the drip hot water channel and the central hot water channel of the hot water channel in the upper cover of the brewing component, and then disperses and flows out from the small holes; when the drip pot is pushed in, the cup cover of the drip pot pushes open the water blocking seat, the water blocking silicone opens, and the coffee flows into the cup; when the drip pot is taken out, the water blocking seat is reset under the action of the spring, keeps it horizontal, and the water blocking silicone is closed.

According to the characteristics of the K-cup coffee capsule package, the flow of hot water and the brewing time are accurately controlled to ensure that the taste and concentration of the coffee meet the standards.

[0040] When the K-cup capsule cup holder is placed in the coffee basket and the upper cover of the brewing component is closed, the ring on the top of the K-cup capsule cup holder abuts against the sealing top rod to seal the drip hot water channel of the hot water channel, and hot water enters through the central hot water channel of the hot water channel; at the same time, when the K-cup capsule cup holder is placed in the coffee basket, the lower edge of the skirt of the K-cup capsule cup holder drives the guide rod to move downward to open the water stopper below. The above American K-cup function module does not require a drip pot, but a small cup or other mug can be placed.

[0041] The detection working principle of the American drip function module is as follows: a first Hall switch component is provided on the left side of the brewing component. When the brewing component is placed in the machine body, the upper cover of the brewing component is closed, the safety switch component is turned on, and a first induction magnet is provided on the guide rod on one side of the brewing component, which forms a detection conduction with the first Hall switch component. The machine body program recognizes and displays that it can be operated as the default American drip brewing related functions.

[0042] The detection working principle of the American K-cup function module is as follows: a second Hall switch component is provided at the upper rear position of the brewing component, and a second induction magnet is provided on the skirt of the K-cup capsule cup holder. After the K-cup capsule is placed in, the upper cover of the brewing component is closed, and the safety switch component is turned on. When the second Hall switch component forms a detection conduction, the body program display can be operated as the default K-cup American drip brewing related functions.

[0043] The Italian extraction function module on the extraction capsule brewing outlet side of the above-mentioned machine has a high-pressure extraction pump and an extraction chamber, which can provide a stable high-pressure environment to deeply extract the coffee powder in the funnel assembly. The extraction chamber is made of high-quality stainless steel material, which has good thermal conductivity and corrosion resistance, ensuring the temperature uniformity of the coffee during the extraction process; and equipped with a precise timing device to monitor the time of the extraction process in real time to ensure the consistency and stability of each extraction. At the same time, the funnel assembly is easy to replace different powder bowls, which can adapt to coffee capsules and coffee powder of different brands and sizes, and has good compatibility; it adopts advanced puncture and water injection technology to ensure that the coffee in the capsule can be fully extracted while avoiding leakage of coffee grounds.

[0044] In summary, the present invention is a coffee machine with five functions, namely, drip, K-cup (K-cup coffee capsule), Italian extraction module, hot water function, and milk frothing, to meet the needs of users for different coffee making methods and improve the versatility and practicality of the coffee machine.
