Description

Brewing machine for coffee machine

The present invention relates to a brewing machine for coffee machines, and more particularly, to simplify the configuration of the pressing means for pressing the coffee particles contained in the cylinder to reduce the manufacturing cost and improve the operation of the components to reduce the compression and removal of the coffee particles. It relates to a brew for a coffee machine that can be facilitated.

Instant drinking coffee sold through vending machines is made by mixing sugar or prim in a fixed ratio in a freeze-dried coffee powder. Freeze-dried coffee for these vending machines not only can not mix sugar or prim according to the buyer's preference, but also has a disadvantage that the taste and aroma are significantly lower than the coffee beans to extract the coffee liquid by grinding the coffee beans on the fly. Therefore, in recent years, a coffee machine for grinding coffee beans on the fly and extracting a coffee liquid is used.

In such a coffee machine, a brewing machine for extracting coffee liquid using high-temperature and high-pressure water by using a grinder for grinding coffee beans and pulverized coffee particles is used.

Such a brewing machine has been disclosed, such as 'apparatus for releasing the compressed coffee grounds from the brewing mechanism of the coffee machine' No. 10-0218815.

As shown in FIGS. 1A to 1C, in the conventional brewing machine (Patent Registration No. 10-0218815), the lower part of the cylinder 1 in which the coffee particles C are accommodated is closed by the lower piston 2. At the upper spindle (4) by the drive spindle (3) to move up to the coffee particles (C) of the cylinder (1) is pressed, at this time, the high temperature and high pressure water is supplied into the cylinder (1) and manufactured through this Coffee liquid is extracted to the outside of the cylinder (1). Subsequently, the cylinder 1 moves downward to the connecting member 5 at the lower side by the driving spindle 3. At this time, the lower piston 2 is inserted while the connecting member 5 is inserted into the hollow of the lower piston 2. The coffee particles C, which are pressed upward while moving upward of the cylinder 1, are pushed out of the upper end of the cylinder 1, and then the discharge part 6 rotatably installed in the cylinder 1 is rotated, so that the coffee particles are rotated. (C) is removed to the outside. Thereafter, the cylinder 1 is moved up to its original position by the drive spindles 3, and the discharge part 6 is rotated to the original position, and the connecting member 5 is inserted from the hollow of the lower piston 2. As it is released, the upper end of the lower piston 2 has a state located below the cylinder 1.

Accordingly, when the O-

rings

2a and 5a are worn and do not have a normal function according to repeated operations of the cylinder 1, the lower piston 2, and the connecting member 5, which are the pressing means of the brew, that is, the lower When the O-ring 2a of the piston 2 wears, the upper end of the lower piston 2 is placed on the lower side of the cylinder 1 when the coffee particles C are received in the cylinder 1 or when the cylinder 1 is raised. With the problem that it is difficult to quantitatively receive the coffee particles (C), the sudden lowering of the lower piston (2) during compression with the upper piston (4) (for example, the lower piston (2) in the center of the cylinder (1) ) Is located in the upper end portion of the upper piston 4 when the upper end is lowered to the lower side of the cylinder (1) due to the problem that the compression efficiency is lowered.
