Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a beverage extraction device that extracts beverages such as tea, coffee, black tea, etc. and supplies them to a cup.

(Prior Art) As an example of this type of device, a coffee brewing device for a vending machine will be described with reference to FIG.

In the figure, a coffee brewing mechanism 5 including a brewing cup 6, its transfer mechanism, a cylinder 3, a piston 4, and a cam mechanism 5a is provided.

This operation will be explained.

After inserting a coin, when the selection button is pressed, ground coffee from the coffee raw material container 8 is supplied into the guide shooter 10.

Next, the extraction mechanism is operated by the cam mechanism 5a driven by the motor.

The brewing cup 6 receives ground coffee from within the guide shooter 10 while being drawn directly below the cylinder 3, and stops immediately below the cylinder 3.

Cylinder 3 descends.

The hot water supply electromagnetic valve 13 is energized, and hot water is supplied into the cylinder 3.

Coffee liquid is extracted by the descent of the piston 4 and is supplied to the cup 20 through the brewing nozzle 61.

After the extraction is completed, the cylinder 3 and piston 4 rise.

The extraction cup 6 returns to the standby position (position A in the figure).

(Problem to be solved by the invention) By the way, in this type of extraction device, compressed air is usually passed through the coffee grounds in order to minimize the amount of water remaining in the coffee grounds after the extraction is completed. This compressed air is produced by extracting and compressing the air between the surface of the hot water supplied in the cylinder and the piston. However, this compressed air scatters the liquid when it exits the extraction nozzle. This scattered liquid adheres to the outer circumferential surface of the cup, staining the hands of the person taking it out, and staining the surroundings of the cup holder, etc., which is undesirable from a sanitary and aesthetic point of view.

In order to solve this problem, the present applicant has provided a device in which an extraction funnel is installed directly below the extraction cup 6 (Japanese Utility Model Publication No. 45039/1983). This will be briefly explained below.

In Fig. 8, ground coffee is in the brewing cup 6, hot water is supplied in the cylinder 3, and the piston 4
It shows the state in the middle of descent, that is, the state in which coffee is being extracted.

Some of the coffee liquid that has passed through the filter 62 directly below the brewing cup 6 becomes droplets from the brewing nozzle 61 and scatters as shown by the arrow. On the other hand, by providing the extraction funnel 63 directly below the extraction nozzle 61, the droplets can be concentrated in one place and poured into the cup 20 without being scattered around. This brewing funnel 63 is provided at a beverage outlet formed around the cup 20, which includes part of the brewing mechanism.

However, since the extraction funnel 63 is installed inside the beverage extraction device main body 1 by screwing or the like, it requires maintenance and maintenance.
When cleaning, etc., the door of the vending machine had to be opened and then the screws removed, which was time-consuming and troublesome.

The present invention aims to solve these problems by making it possible to easily attach and detach parts corresponding to the above-mentioned extraction funnel even from the beverage outlet.

(Means for solving the problem) The present invention supplies the extraction raw material to the extraction cup at the extraction raw material receiving position, moves the extraction cup to the extraction position directly under the extraction mechanism by the extraction cup transfer mechanism, and In the beverage extraction device, the hot water is supplied under pressure to the extraction mechanism to extract an extract from the extraction raw material, and the extracted liquid is caused to flow out through an extraction nozzle into a cup placed at the beverage outlet, the beverage outlet being configured. A substantially circular funnel hole with a brim recess on the inner periphery is provided in the ceiling wall, and the funnel hole has an outer diameter slightly smaller than its inner diameter and has the brim recess in the upper part of its outer circumferential surface. A funnel is provided with a convex portion having a width that allows passage through the convex portion, and the funnel has a convex portion having a width such that the concave portion can pass through the concave portion at the center of the outer peripheral surface of the funnel. It is characterized in that it is provided in a staggered manner so that it can be attached and detached from the beverage outlet to the funnel hole.

(Function) According to the present invention, when the extractor is in use, the funnel is installed on the ceiling wall by resting on the edge of the funnel hole, and the lower part hangs down from the ceiling wall, allowing extraction. To prevent the extract from scattering when the extract is supplied between the nozzle and the cup. When inspecting or cleaning the funnel, rotate the bottom of the funnel from the beverage outlet with your fingers so that the brim corresponds to the brim recess in the funnel hole, and then pull down the funnel. The convex portion of the funnel then engages with the edge of the hole. From this state, turn the funnel again so that the convex part corresponds to the brim recess in the funnel hole, and then pull down the funnel to remove it from the funnel hole. To reattach the funnel to the ceiling wall, simply reverse the above steps.
