Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a beverage extraction device for obtaining an extracted beverage by pouring hot water into raw material powder and filtering it through a filter. (Explanation) Conventional technology Generally, hot water is poured into a powdered raw material such as Fuhi powder, and the mixed liquid of the powdered raw material and hot water passes through a filter made of paper or the like under its own weight to obtain a filtered and extracted beverage. Although this beverage brewing device has a simple configuration and is inexpensive, it takes about 3 minutes to brew one cup of beverage, which takes too much time. In addition, a beverage extraction device that can complete extraction in a short time, such as that used in a vending machine, has a cylinder with a piston mounted on a filter block, such as the Fresh Pull coffee extraction device disclosed in Japanese Utility Model Application Publication No. 60-57885. This system shortens the time it takes to filter coffee by pressurizing the piston while supplying regular coffee powder and hot water into the cylinder, and also removes the extraction residue remaining on the top of the filter after the extraction is complete. Since a removal device is also required, the configuration becomes complicated and expensive.

For this reason, as a beverage supply device that has a simple configuration and shortens the time required to extract a beverage compared to a beverage extraction device that uses its own weight to filter the extracted beverage, a cartridge-shaped beverage supply device that is equipped with a filter and contains powdered raw materials is recommended. Beverage brewing apparatuses have also been considered in which hot water is forced into a powder receiver using a pump, and the powder receiver is replaced when extraction is completed.

(c) Problems to be Solved by the Invention In the beverage extraction device described above, which shortens the time required to extract a beverage by force-feeding hot water to the cartridge-shaped powder receiver,
Since hot water is forced into the powder receiver, a load is applied to the support section that supports the powder receiver.

For example, the diameter of the top surface of the powder receiver that receives the pressure of hot water is 6cIT.
If it is +, the surface area is 2B. 26effl", and the pressure of the hot water is normally 0.5 atm, and the maximum is 1 atm, so a maximum force of 28 kg is required to support the powder receiver. Also, the support part that supports the powder receiver is as described above. Even if the powder receptacle can withstand the load, it takes time to replace the powder receiver and the time required for the replacement operation becomes long, and when selling beverages using such a beverage dispensing device, there is a problem that sales efficiency decreases. .

In order to solve the above-mentioned problems, the present invention provides a powder receiver that is held between the upper lid part provided on the upper lever and the support part provided on the lower lever, and the upper lid part and the support part provided on the lower lever by a clamping means. is crimped and hot water is force-fed to the powder receiver, and based on the upward rotation of the upper lever, the powder receiver placed on the support part is pushed up by the push-up member to withstand the load when hot water is force-fed. To provide a beverage brewing device in which a powder receiver can be easily replaced.

(2) Means for Solving the Problems The present invention has been made to solve the above-mentioned problems, and extracts a beverage by force-feeding hot water to a powder receiver equipped with a filter and containing raw material powder inside. a beverage brewing device that replaces the powder receiver when the brewing is completed;
The powder receiver is held between a lower lever having an extract liquid outlet opening at the bottom and a support part on which the powder receiver can be placed, and the upper lid part and the support part. a clamp means for crimping the upper lid part and the support part;
Transmission means for transmitting the upward rotational force of the upper lever to the lower lever to rotate the lower lever downward;
The above-mentioned problem is solved by a beverage brewing device including a push-up member that fits into the extract liquid delivery port and pushes up the powder receiver when the lower lever is rotated downward.

(*) Function According to the beverage supply device of the present invention, when extracting a beverage, the powder receiver is held between the upper lid part provided on the upper lever and the support part provided on the lower lever, and the powder receiver is used by the clamping means. The upper lid part and the support part are crimped to resist the load that occurs when hot water is forced into the powder receiver, and in this state hot water is forced into the powder receiver through the hot water inlet opened at the top of the upper cover part. Then, the extract can be extracted from the extract outlet opening at the bottom of the support part without any problem. In addition, when replacing the powder receiver, if the clamp means releases the upper lid part and the support part and then rotates the upper lever upward, the transmission means transmits the rotational force to the lower lever, causing the lower lever to move downward. The used powder receiver is pushed up and separated from the support by rotating the push-up member into the extract liquid delivery port, thereby making it easier to remove the powder receiver.
