Definitions
- the invention relates to an espresso machine with a brewing piston which can be displaced in a brewing cylinder according to the preamble of claim 1.
- the brewing piston is in a force-locking connection with a motorized actuating device, specifically via a rod which is mounted in a vertically displaceable sleeve with a tube section (EP 0 270 1 41 A1).
- the tube section is connected, inter alia, via a tension spring to the pin of a cam disk which is driven by a geared motor.
- the tension spring is arranged and dimensioned such that the coffee powder filled into the brewing chamber of the brewing cylinder is compressed by the geared motor essentially constantly and regardless of the amount of powder.
- a brewing water inlet which is in brewing water-conducting connection with the brewing chamber, opens into the brewing cylinder, specifically via a filter with an annular opening, which cooperates through a displaceable closure piece to open a passage.
- the brewing piston is to be held in its position compressing the ground coffee when the brewing water flowing into the brewing cylinder or brewing chamber is pressed.
- an outlet sieve is arranged, which can be raised to push out the ground coffee cake formed after the brewing process.
- the compression of the ground coffee is provided in such espresso machines to achieve a good crema, which also determines the quality of the espresso, since the compressed ground coffee forms a throttle section for the brewing water and a brewing pressure is thereby generated in the brewing cylinder, which presses the essential oils from the ground coffee, which form the crema.
- a construction with a housing-fixed lower part and a carousel that can be rotated relative to it on a circular path of 360 ° as the upper part with a control mechanism is known in order to produce espresso in a very good quality in a simple yet very reliable manner.
- a brewing piston as part of the upper part, is aligned in its one rotational position axially with a brewing chamber or brewing chamber, in order to be able to be lowered into it or raised therefrom. Specifically, after the ground coffee has been poured in, the brewing piston is lowered into the brewing position with a brewing sieve in the brewing chamber until the brewing piston striking the ground coffee has compacted the ground coffee.
- locking elements are effective, which cooperate with a lowering lever and thereby fix the position of the brewing piston before and during the introduction of the brewing water through the holes of the lifting piston into the brewing chamber.
- the latching elements comprise several latching traps to enable different amounts of coffee to be compressed.
- a reciprocating piston is arranged, which is perforated for the passage of the brewing water from the brewing water nozzle embedded in the bottom into the brewing chamber.
- the reciprocating piston is slidably mounted and can be moved up and down by the rotary movement of the upper part. This allows the piston to be raised after brewing the espresso when the upper part is rotated into a different angular position up to the upper edge of the brewing chamber.
- the ground coffee cake remaining after the brewing process can be pushed off to the side with a clearing element.
- the tight confinement of the ground coffee between the perforated piston and the brewing sieve also means that after the brewing process, only a little residual water remains in the ground coffee cake, which is also referred to as the coffee sump.
- the known espresso machines mentioned above can have the disadvantage that not all zones of the ground coffee are adequately moistened at high, either by the highly compressed ground coffee or the back pressure formed by the creme valve, and the essential oils are therefore inadequately squeezed out in these areas.
- Both Espresso machines with a crema valve can be disadvantageous in that when the target opening pressure is reached and the creme valve is opened accordingly, a sudden channel-like breakthrough of the brewing water takes place in the shortest way in the direction of the espresso outlet, with zones of the ground coffee being insufficiently leached out. But even at relatively low pressures and in the absence of a cream valve, undesirable breakthrough channels of the brewing water can form in the ground coffee.
- a known espresso machine of the type mentioned does not have a cream valve, but a spring-loaded brewing piston arranged in the brewing chamber in such a way that it is displaced to the bottom of a brewing chamber by the pressurized brewing water against the restoring force of the spring, thus expanding a brewing chamber and finally on The floor closes a passage to an espresso spout (EP 0 948 927 A1).
- the brewing flask carries a filter on its top, which absorbs the ground coffee, and has a piston rod at the bottom.
- through-channels in the brewing flask through the base in particular an elevation of the base, should be practically closed off from the espresso outlet when the brewing piston is seated on the base or the elevation of the base.
- the brewing chamber is not closed immediately, but only after the pressure has built up to such an extent that the brewing piston is largely pressed onto the floor. At least until then, brewing water can escape from the espresso spout in an undesirable manner. Even afterwards, the tightness is not guaranteed due to unavoidable sediment from the coffee cake and the incompressible water between the underside of the brewing flask and the bottom of the brewing chamber. Therefore, the restoring force of the spring must not be very large, which after the end of the brewing phase, when the supply of hot brewing water is switched off under pressure, resets the brewing piston, including the coffee cake.
- the present invention is therefore based on the object of creating an espresso machine of the type mentioned at the outset, in which, while avoiding the above disadvantages, uniform moistening, pressing out and leaching out of all zones of the ground coffee in the brewing cylinder take place reliably, whereby the best possible use of the ground coffee and an optimized crema should be achieved.
- the sealing of the brewing chamber should also be improved from the beginning of the brewing water inlet into the brewing chamber until the end of the brewing phase.
- the solution according to the invention not only ensures that the ground coffee is compressed by the brewing piston before the actual brewing process, the brewing piston being able to rest on the ground coffee via a water distributor.
- This compression position of the brewing piston before the start of the brewing process is also referred to as the first position the brewing room is sealed pressure and watertight by the brewing flask and downstream by a cream valve.
- the spring is dimensioned so that the brewing cylinder is moved by the pressure of the brewing water flowing into the brewing room against the spring force of this spring into a second position in which the volume of the brewing room is increased to a predetermined maximum value, so that in the Ground coffee in the expanding brewing room does not have any local breakthroughs for the brewing water, but that the ground coffee, due to its mobility, in particular its swirling in a floating infusion, is uniformly moistened, pressed out and leached out before the creme valve opens when the desired opening pressure is reached.
- the brewing plunger is automatically moved back to the first position by the energy stored in the spring, so that the coffee sump or ground coffee cake is dry in the desired manner after the brewing process has ended - no additional active control elements for controlling the movement of the brewing plunger between the first position (compression position) into the second position and back into the first position before excavating the ground coffee cake.
- This function of the brewing piston results from the arrangement and dimensioning of the means which exert a force on the brewing piston during the brewing process, i.e. the brewing pressure in the brewing chamber, the effective brewing piston surface on which the pressure acts, the spring and possibly other elements which the forces acting on the brewing piston influences.
- the cream valve contributes to the automatic displacement of the brewing piston, which also determines the maximum adjustment of the brewing piston and thus the expansion of the brewing space until it reaches its target opening pressure. Mechanical stops or other additional means for limiting the brewing piston stroke are therefore not necessary.
- the target opening pressure can, for example, be set to approximately 6 bar.
- Claim 2 specifies a particularly compact, reliable and structurally uncomplicated arrangement of a compression spring which acts on the brewing piston.
- the targeted automatic displacement of the brewing piston in the brewing cylinder during the brewing process can also be easily inserted into espresso machines of the type which have a lower part which is fixed to the housing and a carousel which can be rotated on a circular path of 360 ° as the upper part, the brewing piston as part the upper part in an angular position of the upper part with a lowering lever in the brewing space can be lowered and raised from it, whereby the upward and downward movement of a reciprocating piston with perforated bottom is positively controlled by the rotary movement of the upper part, which in the brewing chamber in the lower part up to the upper edge the brewing chamber can be raised, from where a ground coffee cake can be pushed laterally with a clearing element.
- This type of construction is shown in detail in EP 0 756 842 B1 mentioned above. The advantages of an uncomplicated, reliable control mechanism can thus be used, with no expansion of this control mechanism being necessary for the brewing piston movement during the brewing process.
- FIG. 1 shows a longitudinal section through part of an espresso machine, in which a brewing head is shown in longitudinal section in a highly simplified manner.
- Fig. 1 denotes a brewing cylinder in which a brewing piston 2 is slidably mounted.
- the brewing piston 2 is sealed against an inner wall of the brewing cylinder 1 by a piston seal 3.
- a water distributor 4 which is designed as a sieve can be and is movable with the brewing piston 2.
- an outlet sieve 5 is located in a lower part of the brewing cylinder 1.
- a brewing chamber 6 of variable volume is defined by the underside of the brewing piston with displaceable water distributor 4, the outlet sieve and the inner wall jacket section of the brewing cylinder between the brewing piston 2 or water distributor 4 and the outlet sieve.
- a cream valve 7 with a target opening pressure of approximately 6 bar is arranged under the outlet sieve in a flow path downstream of the brewing chamber 6 to an espresso outlet 8.
- the outlet sieve 5 can be realized as a perforated bottom.
- a tubular brewing water inlet 9 is connected to a flexible water hose 1 0, which leads to a brewing water pump, not shown.
- the brewing water inlet is designed as a tubular piston rod, which is displaceably mounted in a brewing cylinder carrier 1 1, and merges into a bore in the brewing piston 2, which is in brewing water-conducting connection with the brewing chamber 6 under the water distributor 4.
- a compression spring 1 4 is supported between an upper part of the brewing piston 2, which is not shown, and an underside of the brewing cylinder support 1 1, which is also not shown.
- the compression spring 1 4 is dimensioned so that in the first position of the brewing water piston shown in FIG. 1 at normal pressure in the brewing water inlet it compresses the ground coffee poured into the brewing chamber to a desired extent, however, when the brewing water begins through the flexible water hose at the beginning of the brewing process 1 0 and the brewing water inlet 9 is pressed through the water distributor 4 into the brewing chamber 6, under the pressure of the brewing water upwards to a predetermined second position and accordingly the volume of the brewing chamber 6 while raising the brewing piston 2 with the water distributor 4 in a desired Dimensions enlarged. This brewing piston 2 is raised against the spring force of the compression spring 1 4 until the desired opening pressure of the cream valve 7 is reached.
- the ground coffee can spread in the widening brewing chamber 6, swirled by the pressure of the brewing water flowing into the brewing room 6, in order to be evenly moist, then to be squeezed and leached out.
- the second position of the brewing piston 2, which is reached until the internal pressure in the pressure chamber has risen to the desired opening pressure of the cream valve 7, can be defined, for example, by the characteristic of the compression spring 1 4 in relation to the effective pressure area on the underside of the brewing piston 2 or by a mechanical stop.
- the internal pressure collapses there and the compression spring 1 4 presses the leached coffee grounds in the reducing pressure chamber 6 via the brewing piston 2 and the water distributor 6 until the first position is practically again of the brewing piston 2 is reached.
- the brewing cylinder 1 attached to the brewing cylinder carrier 1 1 by means of a bayonet lock 1 2 can be removed from the brewing cylinder carrier 1, the brewing piston 2 with water distributor 4 and compression spring 1 4 remaining on the brewing cylinder carrier 11.
- the ground coffee can be poured into the removed brewing cylinder 1 before the preparation of the espresso and after the brewing process the ground coffee cake can be removed from the brewing cylinder 1, which in turn has been removed.
