Description

The present invention relates to a beverage extracting apparatus for obtaining a beverage extracted by pouring hot water into raw material powder and filtering through a filter.

(B) Conventional technology Generally, hot water is poured into a powdered raw material such as coffee powder, and a mixed liquid of the powdered raw material and hot water is passed through a filter formed of paper or the like by its own weight to obtain a filtered and extracted beverage. Although the beverage brewing device of the above is simple in construction and inexpensive, it takes about 3 minutes to brew a cup of beverage, and it takes too much time to brew the beverage.

In addition, a beverage brewing device that completes brewing in a short time, such as that used in a vending machine, has a cylinder with a piston on a filter block like a fresh brewed coffee brewing device disclosed in Japanese Utility Model Publication No. 60-57885. This is to shorten the time for filtering the coffee by pressurizing the piston in a state where the powder and hot water of the regular coffee are supplied into the cylinder, and furthermore, the extraction residue remaining on the upper surface of the filter after the extraction is completed. Since we also need a device to remove,
The structure becomes complicated and expensive.

For this reason, as a beverage supply device that is easily configured and shortens the time required for beverage extraction compared to a beverage extraction device of a type that filters an extracted beverage by using its own weight, a cartridge-like shape including a filter and containing powdered raw materials is provided. A beverage extraction apparatus of a type in which hot water is pumped into a powder receiver using a pump and the powder receiver is replaced when the extraction is completed has also been considered.

(C) Problems to be Solved by the Invention In a beverage extraction device of the type in which hot water is pressure-fed to the above-mentioned cartridge-shaped powder receiver to shorten the time required for extracting a beverage, the hot water is pressure-fed to the powder receiver. A load will be applied to the support for supporting the powder receiver.

For example, if the diameter of the top surface of the powder receiver receiving the pressure of hot water is 6 cm, the surface area is 28.26 cm ² , and the pressure of hot water is 0.5 atm for normal use and 1 atm at the maximum, so the powder receiver is supported. The power will need up to 28kg.

Also, even if the supporting portion supporting the powder receiver can withstand the above load, if the time required for the replacement of the powder receiver is long and the replacement operation is long, when selling the beverage with such a beverage supply device, There is a problem that the sales efficiency is reduced.

The present invention solves the above-mentioned problem by clamping the upper lid portion and the support portion by clamping means while holding the powder receiver between the upper lid portion provided on the upper lever and the support portion provided on the lower lever. And presses the hot water to the powder receiver, and the powder receiver placed on the support part is pushed up by the push-up member based on the upward rotation of the upper lever, so that it can withstand the load when the hot water is pumped. The present invention is to provide a beverage extraction device that can perform the above-mentioned process and can easily replace the powder receiver.

(D) Means for Solving the Problems The present invention has been made to solve the above problems, and the extraction of a beverage is performed by pumping hot water into a powder receiver having a filter and containing a raw material powder therein.

I do.

(E) Action According to the beverage supply device of the present invention, at the time of beverage extraction, the clamp means is used in a state where the powder receiver is held between the upper lid portion provided on the upper lever and the support portion provided on the lower lever. The upper lid and the support are pressed against each other to counteract the load generated when the hot water is pumped into the powder receiver. Then, the extract can be extracted from the extract outlet at the lower part of the support portion without any trouble. Also, when replacing the powder receiver, release the crimped state of the upper lid and the support by the clamping means,
If the upper lever is further rotated upward, the transmitting means transmits the rotating power to the lower lever, and rotates the lower lever downward to insert the push-up member into the extract liquid outlet to remove the used powder receiver. It is spaced from the push-up support to facilitate removal of such a powder receiver.
