Description

Filter-plate structure in coffee-making machine brewing chamber

Technical field

The present invention relates to a kind of parts of coffee machine, the filter-plate structure specifically in a kind of coffee-making machine brewing chamber.

Background technology

The chamber lower end of brewageing of coffee machine is communicated with the water inlet pipe of coffee machine, a gangbar is sheathed with in water inlet pipe, filter plate is fixed in gangbar, namely the center of gangbar upper end and filter plate lower surface is fixed, filter plate other fringe region except central area is provided with multiple filter opening, and filter plate will be brewageed chamber and be separated into upper chamber and lower chambers.When brewageing, ground coffee is placed on filter plate upper surface and namely brewages in the upper chamber of chamber, people rotate the handle of coffee machine, gangbar is driven to rise through transmission mechanism again, final drive filter plate also rises, and water enters the lower chambers brewageing chamber from water inlet pipe, then enter upper chamber through the filter opening of filter plate and mix with ground coffee, with brewing coffee.

There is following defect in the filter-plate structure in the coffee-making machine brewing chamber of prior art: because the central area of filter plate does not arrange filter opening, current are through filter plate, upper chamber can only be poured from each filter opening of fringe region, and filter plate central area does not have water to flow through at the beginning, the middle diffusion of the current direction of fringe region can only be waited for, like this, the ground coffee being positioned at filter plate central area cannot fully mix with current the very first time, and what affect coffee brews mouthfeel; But the central area of filter plate needs to be connected and fixed with gangbar, and it is solid for which results in filter plate central area, cannot arrange filter opening, and this just constitutes the technical barrier that coffee brewing is brewageed at all.

Summary of the invention

The technical problem to be solved in the present invention is, provides the filter-plate structure in a kind of coffee-making machine brewing chamber that the ground coffee of regional on filter plate can be made fully to mix with current the very first time.

Technical solution of the present invention is, filter-plate structure in a kind of coffee-making machine brewing chamber is provided, it comprises filter plate body and gangbar, filter plate body central is solid area, the solid area of gangbar upper end and filter plate body is fixed, and the acentric circle ring area of filter plate body is provided with multiple through hole, and filter plate body upper surface is provided with many from the outward extending reinforcement of solid area, whole reinforcement is uniformly distributed along filter plate body circumference, and every bar reinforcement is outer low and inner high; This filter-plate structure also comprises a curved surface filter disc covered above filter plate body, and the upper surface of curved surface filter disc and whole reinforcement is fitted, and curved surface filter disc is evenly distributed with multiple filter opening, forms mixing chamber between curved surface filter disc lower surface and filter plate body upper surface.

Adopt filter-plate structure in the coffee-making machine brewing chamber of above structure compared with prior art, have the following advantages:

Water is through entering the process of upper chamber from lower chambers through filter plate body, first through each through hole of filter plate body, now, the non-central circle ring area being provided with through hole of filter plate body is only had to have water, and the solid area of filter plate body central there still is not water, but owing to there is mixing chamber between filter plate body and curved surface filter disc, like this, water through filter plate body directly can not enter upper chamber, but cambicly fully to mix in mixing chamber, each filter opening again through curved surface filter disc enters upper chamber, and each filter opening on curved surface filter disc is uniformly distributed, and filter opening aperture is much smaller than through hole, therefore enter into the water center of upper chamber or edge is all uniform through curved surface filter disc, like this, the ground coffee being positioned at optional position on curved surface filter disc can both mix with water the very first time, so ensure that and brew mouthfeel, also the technical barrier that prior art filter plate body central region cannot arrange filter opening is naturally solved.

As improvement, reinforcement is even number bar, the upper surface of filter plate body also comprises many arc dowels, whole arc dowel is uniformly distributed along filter plate body circumference, the two ends of every bar arc dowel are connected with the inner of adjacent two reinforcements respectively, the number of reinforcement is the twice of arc dowel number, like this, in fact, many arc dowel interval is laid, the bulk strength increasing structure of maximum possible, and can not stop that again the water in mixing chamber spreads to central area, ensure that the uniform fluid flow finally entering upper chamber.

As preferably, the excircle of curved surface filter disc is provided with multiple downward elasticity inserted sheet, each elasticity inserted sheet lower end is provided with in-flanges, filter plate body is through with and elasticity inserted sheet elongated hole one to one, each elasticity inserted sheet inserts in corresponding elongated hole and the in-flanges of this elasticity inserted sheet is stuck in the end opening of elongated hole, like this, the elasticity inserted sheet of curved surface filter disc is only needed to insert in elongated hole corresponding on filter plate body, after being inserted into position the in-flanges of elasticity inserted sheet can eject and automatic clamping at the end opening of elongated hole, this Standard is convenient and swift, and assembling rear curved surface filter disc and being connected firmly of filter plate body.
