Abstract

The utility model relates to a foam production and drainage structure of a high pressure coffee machine, which is characterized in that a partition board is arranged in a coffee container; the bottom of the container is provided with a guide outlet, the top at the circumference of the container is provided with one or more than air inlet grooves, and the bottom surface of the container is convexly provided with a convex body; the position of the partition board corresponding to the convex body is provided with a through hole, and the position of the through hole corresponds to that of the guide outlet of a coffee containing basket; the partition board is arranged above the convex body in order to make a spacing layer arranged between the bottom of the coffee containing basket and the partition board when the coffee containing basket is arranged in the container. In such a way, coffee oil of the coffee guided out from the coffee containing basket can be mixed with fresh air guided into the coffee container, and the utility model can generate an optimal foaming effect; when coffee foam is guided out via the through holes of the partition board, the coffee foam can strike the convex body at the bottom of the container and diffuse towards the outer side of the utility model, and thus, the phenomenon that the shaped foam disappear due to the continuously striking of the following guided coffee can be prevented; the coffee with the optimal foam can be guided out from the guide outlet of the container, and the flavor of the coffee is improved.

Description

High pressure coffee machine foam produces and flow guiding structure

Technical field

The utility model relates to a kind of high pressure coffee machine foam and produces and flow guiding structure.

Background technology

Known high pressure coffee (espresso) machine mainly is to fetch water with the pressure of about 10kg/cm2 by high-pressure pump to enter a heater and water is heated to about 94 ℃, shown in figure five, coffee powder 1 ' places the coffee with filtering function to contain in the basket 2 ', and this coffee Sheng basket 2 ' below is provided with filter screen 21 ', and this coffee contains that basket 2 ' places in the container 3 ' and with container 3 ' top driving fit, and and has wall 4 ' between container 3 ', in container 3 ' below export mouth 31 ' is set again, and when making this container 3 ' with the combination of high pressure coffee machine coffee contain basket 2 ' can with the delivery port driving fit (indicating among the figure) of high pressure coffee machine.

The high thermal high water of high pressure coffee machine injects in the coffee Sheng basket 2 ' again, and melt, extract material in the coffee powder 1 ', for example caffeine, fragrance, caffeol, flow out by filter screen 21 ' again, and the caffeol that should flow out coffee combines with the air of wall 4 ' and forms foam, derived by export mouth 31 ' again.

Caffeol combined with wall 4 ' interior limited air when yet aforementioned structure was derived by filter screen 21 ' because of coffee, thereby cause air capacity not enough and cause foam to form the shortcoming of poor effect, the minority foam of this container 3 ' top formation directly impacts because of being subjected to follow-up coffee of being derived by filter screen 21 ' again, cause this established coffee foam to be impacted the disappearance situation, make the foam of deriving significantly reduce, reduced the flavor taste of coffee by export mouth 31 '.

The utility model content

Main purpose of the present utility model provides a kind of high pressure coffee machine foam that produces and derive preferable foam and produces and flow guiding structure.

The technical solution of the utility model is such: high pressure coffee machine foam produces and flow guiding structure, be provided with dividing plate in the coffee container, and this container bottom is provided with export mouth, in said vesse periphery top one or more air inlet duct is set, and is convexly equipped with convex body in this container bottoms again; Aforementioned barriers is provided with through hole corresponding to the position of above-mentioned convex body, and this lead to the hole site and coffee to contain basket export mouth position corresponding, and dividing plate places the top of convex body, so that this coffee is contained between basket bottom and dividing plate and had wall when coffee being set in the container containing basket.

Above-mentioned air inlet duct comprises the recess that is arranged at the said vesse top and is located at the rectangular groove of said vesse medial surface to should recess location being provided with, and the bottom of this rectangular groove is corresponding to the position of aforementioned barriers.

The utility model high pressure coffee machine foam produces and flow guiding structure, outside air can be imported in the wall by air inlet duct, and can mix the preferable foam of generation with the fresh air of continuous importing by the caffeol that coffee contained basket and derive by coffee, and this coffee foam can clash into the convex body of container bottom and diffusion laterally when deriving via the through hole of dividing plate, the foam that can prevent this shaping is subjected to the coffee of follow-up derivation constantly to impact disappearance, like this, the container export mouth just can be derived the coffee with preferable foam, thereby promotes coffee flavor.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model is provided with dividing plate 2 in coffee container 1, and container 1 bottom is provided with export mouth 11, and one or more air inlet duct 12 is set in container 1 periphery top, air inlet duct 12 comprises the recess 121 of being located at container 1 top and is opened in the rectangular groove 122 that container 1 medial surface corresponding recess 121 positions are provided with, and the bottom of rectangular groove 122 is corresponding to the position of dividing plate 2, and container 1 bottom surface convexes with convex body 13.

Dividing plate 2 is provided with through hole 21 corresponding to the position of convex body 13, and the position of through hole 21 is corresponding with the position that coffee is contained basket 3 export mouths 32, dividing plate 2 places the top of convex body 13, so that this coffee is contained basket 3 bottoms and 2 on dividing plate has wall 22 when coffee being set in the container 1 containing basket 3, coffee is contained basket 3 inside and is provided with the filter screen 31 that can extract again, and filter screen 31 is provided with export mouth 32.

As shown in Figure 4, the coffee Sheng basket 3 of coffee powder 4 has been filled in setting in the container 1 of the present utility model, high pressure after container 1 and high pressure coffee machine (indicating among the figure) make up, the water of high temperature can inject coffee Sheng basket 3 and melt, material in the extraction coffee powder 4 is (as coffee powder, fragrance, caffeol), export mouth 32 by coffee Sheng basket 3 exports to wall 22 again, because outside air can import in the wall 22 from air inlet duct 12, thereby the caffeol that should derive coffee can be mixed by the fresh air of continuous importing, produce preferable foam, and this coffee foam can clash into the convex body 13 of container 1 bottom and diffusion laterally when deriving via the through hole 21 of dividing plate 2, thereby the foam that can prevent this shaping is subjected to the coffee of follow-up derivation constantly to impact disappearance, like this, just can derive coffee from container 1 export mouth 11, thereby promote coffee flavor with preferable foam effect.

In sum, thereby the utility model structure has the effect that can produce and derive better foam lifting coffee flavor, and its effect is better than known product, so propose patent application in accordance with the law.
