Description

Coffee machine with bean grinding function

Technical Field

The utility model relates to the technical field of coffee machines, in particular to a coffee machine with a bean grinding function.

Background

Coffee is one of the most popular beverages in the world. The traditional coffee brewing process needs several processes of baking, grinding, brewing, filtering and the like, and although the traditional coffee making process has good ornamental and interesting properties. But many people do not have time to learn these processes relative to modern fast life; to solve this problem, coffee machines have been developed, which can be operated in the following manner: 1. a hand-brewing coffee machine; hand-brewed coffee machines, also known as drip coffee machines, rely on manual operation and gravity principles to make coffee. Common hand-brewed coffee machines include a law pressing pot, a hand brewing pot, a siphon pot, and the like. 2. A drip coffee machine; the drip type coffee machine is an automatic appliance for flushing coffee, and generally, coffee powder and water are respectively placed into independent containers, the coffee machine pumps water out of a water tank, the water is heated and then automatically dripped into a filter filled with the coffee powder, and the coffee is manufactured in the dripping process. 3. An espresso machine; espresso machines, also known as espresso machines, are machines that make espresso with hot water and high pressure. Common espresso machines are capsule coffee machines, semi-automatic coffee machines, and the like. 4. French press, which is a manual appliance for flushing coffee, mixes coffee powder and water thoroughly by pressure, and infuses coffee with a rich feeling of mouth. The coffee beans need to be manually ground, and the time and the powder amount are mastered. 5. The three-in-one coffee machine can automatically finish the work of grinding, brewing, sugar adding, milk adding and the like. Common three-in-one coffee machines are capsule coffee machines, automatic extraction coffee machines, and the like. 6. The full-automatic coffee machine can automatically finish all the works of grinding, brewing, sugar adding, milk adding and the like. Only press the button or select the setting program to make a cup of coffee easily.

The automatic control of the whole process of brewing coffee by preheating, cleaning, grinding, pressing powder, brewing, purging powder and the like is realized by the Italian coffee machine, hot water at about 90 ℃ is forced to pass through the young extruded coffee powder by using 20 Pa pressure, brewing is completed in a short time, the coffee brewed by the pressurized hot water is thicker than normal, emulsified grease exists, and the milk can be emulsified by high-pressure steam to prepare aromatic milk foam, and coffee in various forms such as cappuccino and the like can be brewed. Chinese patent application publication No. CN206659685U discloses an espresso machine comprising: the quantitative grinding device and the coffee extraction device are provided with a linkage type powder outlet groove mechanism between the quantitative grinding device and the coffee extraction device. The linkage type powder outlet groove mechanism comprises a powder outlet nozzle and a telescopic groove; the first end of the powder outlet nozzle is connected with the quantitative grinding device, and the telescopic groove is movably positioned at the second end of the powder outlet nozzle; the shifting fork linkage assembly is connected between the powder pressing head and the telescopic groove and used for driving the telescopic groove to synchronously stretch along with the movement of the powder pressing head. When the powder pressing head rises, the telescopic groove extends out of the powder outlet nozzle so that the coffee powder falls into the extraction cup downwards. A turnover movable baffle is hinged on the front end part shell of the powder outlet nozzle; when the telescopic groove extends out of the powder outlet nozzle, the powder outlet nozzle jacks up the movable baffle; a torque spring for driving the movable baffle to be closed is arranged between the movable baffle and the front end part of the powder outlet nozzle; when the telescopic groove is contracted, the torque spring drives the movable baffle to turn down and close; the movable baffle can completely shield the outlet of the powder outlet nozzle after being closed, so that the residual coffee powder in the powder outlet nozzle is prevented from continuously falling, and meanwhile, the phenomenon that water vapor in the coffee extraction process enters the powder outlet nozzle and the quantitative grinding device is prevented from causing the coffee powder to wet and harden is avoided.

The coffee machine in the above patent application is to directly deliver ground coffee powder to a coffee extraction device (brewing chamber) and to perform a pressing operation in situ, and although a movable baffle capable of being turned and closed is designed, the movable baffle may have a problem of blocking or poor sealing, so that water vapor in the extraction process enters a powder outlet nozzle and the inside of a quantitative grinding device, and the coffee powder is wetted and hardened.

Therefore, there is a need for further improvements in existing coffee machines.
