Anti-leakage method for coffee machine and anti-leakage coffee machine

Abstract

The invention relates to an anti-leakage method for a coffee machine. After a water pump stops working, the residual high pressure in a brewing chamber is utilized to drain the residual liquid in a capsule from a water inlet surface of the capsule through a decompression water path, under a closed state of the brewing chamber. The invention also relates to an anti-leakage coffee machine which comprises a shell, a piston, a water inlet component, a water draining component and the brewing chamber used for accommodating the capsule, wherein the water draining component comprises a decompression connecting pipe, a decompression pipe and a decompression valve; the decompression connecting pipe is arranged on the shell; the decompression pipe and the decompression valve penetrate through the piston in a sealing form; one end of the decompression pipe is communicated with the brewing chamber while the other end is connected with one end of the decompression connecting pipe; the other end of the decompression connecting pipe is communicated with the decompression water path; the chamber of the decompression pipe is communicated with the decompression connecting pipe so as to form a decompression water channel; the decompression valve is used for controlling the decompression water channel and the decompression water path to connect or close. Compared with the prior art, the anti-leakage coffee machine can effectively solve the leakage problem of the coffee machine caused by the residual liquid in the coffee capsule.

Description

technical field [0001] The invention relates to the field of coffee machines, in particular to an anti-drip method for a coffee machine and an anti-drip coffee machine. Background technique [0002] Capsule coffee machine is a new type of coffee machine that has appeared in recent years. When brewing coffee, this kind of coffee machine only needs to put coffee capsules into a special capsule coffee machine to drink fragrant coffee. Compared with semi-automatic coffee machines and fully automatic coffee machines, capsule coffee machines have the advantages of easy operation, strong coffee, and the ability to keep the quality of each cup of coffee basically the same, so they are sought after by coffee lovers. [0003] After the capsule coffee machine has finished brewing coffee, the coffee liquid remaining in the coffee machine will flow out of the coffee outlet mouth, which is not only inconvenient to clean, but also affects the user experience of consumers. For this reason,...

AI Technical Summary

Problems solved by technology

A general coffee capsule is filled with about 8g of coffee powder, and the coffee powder fully fills the space in the coffee capsule, but the coffee powder in some coffee capsules on the market does not fully fill the interior of the capsule, that is, when this kind of coffee capsule is used, the coffee powder and There will be a gap between the top of the capsule, so that after the coffee is brewed, there will be more liquid in the capsule, so the liquid will drip from the coffee outlet, causing a bad user experience

It can be seen from the above that the anti-drip structure in the above-mentioned first patent solves the problem of dripping caused by the coffee remaining in the coffee inlet pipe, while the anti-drip structure in the above-mentioned second patent solves the problem caused by the remaining water in the water pipe. The dripping problem caused by both of them cannot solve the dripping problem of the capsule coffee machine caused by the insufficiently filled coffee capsules of the above-mentioned coffee powder. It can be seen that the anti-drip technology of the existing capsule coffee machine still needs to be modified.
