Claims

[Scope of utility model registration request]

(1) A cylinder with a piston is assembled on top of a filter block equipped with a filter on the top surface, and with regular coffee powder and hot water being supplied into the cylinder, the piston is moved downwards in the cylinder by the drive of the brewer motor. In a fresh pull coffee extractor that extracts and filters coffee through the filter by pressurizing the raw material by descending toward a point, the speed of movement of the piston that moves up and down in the cylinder is equipped with a means for controlling the operation of the brewer motor. A fresh-pull coffee extractor characterized in that the operation of the brewer motor is controlled so that the speed of the upward stroke is relatively increased compared to the speed of the downward stroke.

(2) Utility Model Registration Scope of the Claim In the fresh pull coffee extractor according to claim 1, the operation control means of the brewer motor includes a position detector for detecting the stroke position of the downward stroke of the piston, and a signal from the position detector. A fresh brew coffee extractor consisting of a brewer motor deceleration controller that operates based on the following.

(3) Scope of Utility Model Registration In the Fretsu Sprü coffee extractor described in claim 2, the deceleration operation controller is a power frequency converter connected to the power supply circuit of the brewer motor, and Due to the operation of the self-running cam as a synchronized position detector, the power supply frequency to the Brewer motor is changed from the commercial frequency to a preset low frequency during the piston's downward stroke, and the Brewer motor is operated at a low speed, thereby decelerating the piston. Threshprew coffee brewer with control. , s (4) Utility model registration In the fresh pull coffee extractor according to claim 2, the deceleration operation controller is a timer that periodically opens and closes a timer contact inserted in the power supply circuit of the brewer motor. , the self-propelled cam stops operating as a position detector in synchronization with the stroke of the piston, and the timer cycle is set in advance on the piston's downward stroke. A fresh brew coffee extractor that operates the brewer motor intermittently to control piston deceleration.
