Problems solved by technology

However, the aforementioned invention suffers from some disadvantages, such as the use of less water than is normally used by stove-top espresso machines, thus obtaining a smaller amount of coffee relative to the production capacity of the stove-top espresso machine, and the inability to obtain particularly hot coffee. coffee
[0006] Moreover, according to the aforementioned invention, the overall dimensions inside the brew collector are large
[0007] Moreover, given the high pressure / temperature at which the aforementioned prior art stove top espresso machines obtain brewed espresso with foam, the The known gasket means between the boiler and the collector are subject to thermal stresses which, after prolonged use, induce significant deformations affecting the functionality of these gasket means and the ease with which the stove-top espresso machine can be disassembled and reassembled
[0008] Furthermore, the overpressure valve devices provided in the aforementioned prior art stove top espresso machines suffer from deposits and / or fouling and residues of coffee grounds which impair the proper functioning of the espresso machine

[0030] The first embodiment ( figure 1 and 2 )

[0031] According to the prior art, in stove-top espresso machines there is known a boiler 3 adapted to contain water to be heated, a filter for holding ground coffee 4 and adapted to receive a predetermined amount of ground coffee per brewing boiler, and a collector 5 suitable for collecting brewed products prepared by passing hot water through ground coffee, wherein an annular rubber gasket 2 is interposed between said boiler 3 and said collector 5, and wherein, with The filter for holding the ground coffee 4 communicates at one side with the interior of the filter 3 and at the other side with the dispensing duct 6 for dispensing the brewed product; The known way comprises a device 10, 10', 20 for dispensing brewed products, said device being arranged on a dispensing duct 6 and comprising a Overpressure valve device 19.

[0032] According to the invention, said device 10, 10', 20 advantageously comprises ( Figure 1-3 ): ...

no. 2 example

[0044] The second embodiment ( image 3 )

[0045] In a second example of embodiment of a stove-top espresso machine according to the invention, said device 20 comprises ( image 3 ) a first dispensing outlet 21 and a second dispensing outlet 22 of the brewed product arranged in parallel from the dispensing conduit 6, wherein the first dispensing outlet 21 is associated with the overpressure valve device 19 and arranged to dispense a Lima's brewing product, said overpressure valve device 19 includes said opposite elastic member 13" adapted to allow the discharge of the brewing product only when the pressure is greater than a predetermined pressure, the second dispensing outlet 22 is connected to said overpressure valve device 19 is separated and arranged to dispense a brewed product with no crema or with less crema than the brewed product discharged from the first dispensing outlet 21 .

[0046] Said device 20 comprises control means 23 operable manually to allow selective d...

Abstract

Stovetop espresso maker comprising a boiler (3), a filter for holding ground coffee (4), and a collector (5) adapted to collect the brew produced by means of the passage of hot water through the grounds, wherein said stovetop espresso maker also comprises a device (10) for dispensing the brew, which is arranged on a dispensing duct (6) and includes overpressure valve means (19) arranged along a path of said brew from the boiler (3) to the collector (5) and wherein said device (10) comprises: - said overpressure valve means (19), in which a valve body (11) is movable parallel to the axis of said dispensing duct (6), with respect to a corresponding valve seat (12), and opposing elastic means (13), which act on said valve body (11), are housed in a decompression chamber (14) arranged downstream of said dispensing duct (6) and comprising at least one brew dispensing outlet (14.1), and - manual adjustment means of the dispensing pressure (15) of said brew, between at least a first pressure value and a second pressure value, greater than the first, in correspondence of at least one of which said overpressure valve means (19) allow the passage of the brew from said dispensing duct (6) to said at least one dispensing outlet (14.1), so that a brew without foam and with foam can be produced with said stovetop espresso maker.

Description

technical field [0001] The present invention relates to a stove top espresso machine. [0002] In particular, the present invention relates to such a stove-top espresso machine for the preparation of brewed coffee, barley coffee, etc. obtained from coffee grounds or beans, in particular with or without foam Brewed espresso, ie: coffee prepared using a professional espresso machine. Background technique [0003] While many coffee drinkers prefer the aroma of coffee prepared using conventional home coffee machines, they also greatly appreciate the "crema" (foam) that develops on coffee prepared using professional espresso machines. [0004] The main difference between the organoleptic properties of coffee prepared with a professional espresso machine and that prepared with a domestic stove-top espresso machine stems from the difference in the processes used to obtain the two types of coffee: the espresso is prepared using a specialized machine that The machine basically pres...
