Description

Brewing machine with hydraulic system Technical Field The invention relates to the technical field of household appliances, in particular to a brewing machine with a hydraulic system. Background Capsule beverage brewing machines are popular with users because they are more convenient and hygienic than manual brewing. The main reason that the machine brewing is faster than the manual brewing is that the brewing system formed by the brewing machine and the capsule together forms pressure brewing for the beverage raw material placed in the machine, the existence of the pressure promotes the precipitation of effective substances in the beverage raw material, and the pressurized brewing of the capsule beverage is completed in the brewing cavity of the machine. The brewing pressure of the capsule beverage is mostly in the pressure range of 3-12bar, so that the brewing cavity is required to have reliable pressure resistance, and once the pressure-resistant measures fail, the problems of bin bursting, water leakage, hot water splashing and the like in the brewing process are likely to occur, and great potential safety hazards exist. Most of the existing high-pressure-resistant brewing systems are manual purely mechanical locking structures or locking structures in a motor control mode. The manual purely mechanical locking structure (such as a handle type) has the problems that the manual purely mechanical locking structure needs larger force to control during operation and has poor convenience, and the locking structure of the motor control mode not only increases the equipment cost, but also requires a certain time for the actual running of a driving part (such as a motor), and the actual operation acts slower and has poor instantaneity, so that no matter which mode is adopted, the stable pressure-resistant environment cannot be formed effectively for the brewing cavity. Aiming at the problem that the existing brewing machine in the related art cannot efficiently form a stable pressure-resistant environment due to the reasons of poor control convenience, high cost and the like when effectively brewing the high-pressure capsule, no effective solution is provided at present.
