Is inserted and held in a groove formed in the inner surface of the hot water supply nozzle in the circumferential direction. The plate can be easily attached and detached, the plate can be easily cleaned, and the plate is regularly cleaned, so that the inside of the cylinder is continuously maintained. Because hot water can be supplied in the form of a shower, a delicious beverage is always extracted at a high concentration.

The invention described in claim 5 is the invention according to claims 1 to 4
In addition to the invention described in any one of the above, the distance between the tip of the hot water injection pipe inserted into the hot water supply nozzle and the center of the plate is 2
When the length is not less than 8 mm and not more than 8 mm, the hot water is easily discharged uniformly from the hot water discharge holes of the plate, and the extraction of the extract of the beverage material is further promoted, so that a delicious beverage can be extracted at a high concentration.

According to a sixth aspect of the present invention, the valve mechanism is hollow, and further includes a plate at the center of the lower surface.
Hot water can be supplied to the beverage material from the center of the cylinder in the form of a shower with the valve mechanism closing the top opening of the cylinder, so that when extracting the beverage, the steam of the hot water leaks out of the cylinder and the temperature of the extracted beverage Since the drop is small, the beverage extract can be extracted at a high hot water temperature, so that a high-concentration delicious beverage can be extracted. Furthermore, since the hot water supply section (plate) for supplying hot water into the cylinder from above the center of the upper opening of the cylinder is integrated with the valve mechanism, the hot water supply section prevents the valve mechanism from closing the upper opening of the cylinder. The configuration for avoiding this is simplified.

According to a seventh aspect of the present invention, in addition to the sixth aspect, an air hole formed in the middle of the hot water injection pipe is opened to close the air hole when air is press-fitted into the cylinder. A hot water tank and a connection port formed in the upper opening of the hole of the valve mechanism by a hot water injection pipe having a hot water valve in the middle of the hot water tank and the air hole valve. The hot water in the hot water tank can be supplied to the cylinder with less variation by opening the hot water tank, and the air is pressed into the cylinder without interfering with the hot water tank and the hot water injection pipe by closing both the hot water valve and the air hole valve. be able to.
