Description
Technical field
The present invention relates to coffee machine field, particularly relate to a kind of coffee machine antidrip method and antidrip coffee machine.
Background technology
Capsule coffee machine is a kind of Novel coffee machine in recent years occurred, only need to be by coffee glue during this kind of coffee machine coffee
Capsule loads in special capsule coffee machine, can drink aromatic coffee.Capsule coffee machine and semi-automatic coffee machine, full-automatic coffee
Coffee machine is compared, and has easy and simple to handle, the advantage such as coffee is aromatic and brewed every cup of quality of coffee can be kept basically identical, therefore
By coffee, fan is pursued.
Capsule coffee machine, after having brewageed coffee, remains in the coffee liquid in coffee machine and also can flow from Coffee outlet mouth
Go out, be not only inconvenient to clean, and the use impression of consumer can be affected.For this Patent No. ZL201520647004.9
The Chinese utility model patent " Anti-dripping structure of a kind of coffee machine " of (Authorization Notice No. is CN 204889669 U) discloses
A kind of structure, it includes housing；Brewage unit and water pump is located in housing；Waste material box is mounted on below housing；Coffee outlet group
Part is located at housing forward end face, and Coffee outlet assembly includes that coffee inlet pipe, airport, the first Coffee outlet pipe and the second coffee go out
Mouth pipe, wherein coffee inlet pipe one end connects with brewageing unit group, and the other end and the first and second Coffee outlet pipes are connected, air
Hole is positioned at above coffee inlet pipe, and the first Coffee outlet pipe is positioned at coffee inlet pipe front lower place, and a retaining wall is located at first and second
Between Coffee outlet pipe and be positioned at the front lower place of coffee inlet pipe lower wall end, second Coffee outlet pipe one end is connected with waste material box
Logical.This patent remains in after the coffee in coffee inlet pipe loses water-aspirator pressure and cannot do parabolic motion, thus at gravity
It is dropped in the second Coffee outlet pipe along coffee inlet pipe under effect and then is flowed in waste material box.
And for example the China of Patent No. ZL201120028375.0 (Authorization Notice No. is CN 201948803 U) is practical new
Type patent " Anti-dripping structure of coffee machine " discloses a kind of structure, and it includes that the coffee brewing being sequentially communicated by water pipe is filled
Put, heating pot, water pump and water tank, between heating pot with coffee-making device, be provided with the outlet check valve and pressure release concatenated
Valve.This relief valve is inverted T-shaped, and one end of the lateral duct part of relief valve is provided with water inlet, and the other end is provided with water outlet
Mouthful, the top of the longitudinal passages part of relief valve is provided with valve gap, valve gap has pressure relief opening.By setting in this patent
It is interior because of pressure produced after having boiled coffee that relief valve can automatically and rapidly shed coffee machine, thus shortens coffee machine
There is the time of water clock at the kettle nozzle, or stop the weeping occurred at the kettle nozzle completely.
Prior art is exclusively used in the coffee capsule of capsule coffee machine when preparing, is that coffee bean is made through special handling
It is sealed in after coffee powder in the capsule being similar to " fruit jelly ", in capsule, is full of nontoxic noble gas simultaneously plays prolongation guarantor
The effect of matter phase sterilizing again.Equipped with about 8g coffee powder in general coffee capsule, and coffee powder is sufficient filling with coffee glue
Space in capsule, but the not sufficiently filled capsule of coffee powder in some coffee capsule, i.e. this kind coffee glue in the market
Can leave gap between coffee powder and the top of capsule when capsule uses, such coffee is quenched after taking, and can remain more in capsule
Liquid, therefore liquid can at Coffee outlet water clock not to the utmost, the experience that cause the user is bad.Therefore, above-mentioned
What the Anti-dripping structure in first part of patent solved is to remain in the dripping problems that the coffee in coffee inlet pipe causes, and above-mentioned
What the Anti-dripping structure in second part of patent solved is the dripping problems caused because of the water of residual in water pipe, and both of which can not solve
The dripping problems of the capsule coffee machine that the not sufficiently filled coffee capsule of above-mentioned coffee powder causes, it is seen then that existing capsule coffee
The antidrip technology of machine need to change.
