    An espresso maker has a brewing unit (1), which comprises a top open brewing chamber (3), a grinder (7) and a feeder channel (11), which protrudes from a Mahlwerkauslauf (10) and up to the brewing chamber (3) in Filling position (I) extends to feed in the grinder (7) ground coffee the brewing chamber (3). In this case, the grinder (7) is arranged inclined to the brewing chamber in the filling position. At least one of the Mahlwerkauslauf (10) remote portion (11 ') of the feeder passage (11) is inclined relative to the horizontal (16) more down to the brewing chamber (3) in the filling position (I) as the grinder (7).

    专利说明:

    The invention relates to an espresso machine according to the preamble of claim 1.
    In a well-known from practice espresso makers both the brewing chamber during filling in filling position and the grinder are arranged vertically in the brewing unit. After the grinding and filling process, the brewing chamber is pivoted for brewing under a brewing piston and pushed over the brewing piston. To previously fill the brewing chamber in filling position with the ground material, ground coffee, protrudes from the grinder a feeder channel from a Mahlwerkauslauf to about the open top brewing chamber. Accordingly, the stock, which is ejected and pushed horizontally out of the grinder outlet from a grinder outlet by the action during the grinding operation of moving parts of the grinder, is moved substantially horizontally to the end of the feeder channel and moreover directly, i. without active separate transport, directed to fall into the open top brewing chamber. However, it has been shown that depending on the nature of the material to be ground and also due to static charges, blockages of the feed channel with the ground material may occur.
    From US 6 101 923 A an automatic coffee machine with two brewing piston is already known, which may extend into two pivotable brewing chambers. Two grinders, which are arranged at an angle of 90 ° to each other, each have a Mahlwerkauslauf leading to a controllable funnel is passed over the freshly ground coffee powder to one of the brewing chambers. To this end, grinder outlets, each with a straight feeder channel to the hopper are arranged on the grinders, which protrude from the grinders over their entire length at right angles.
    The present invention has for its object to avoid the clogging caused by the susceptibility of the filling process of an espresso machine (better).
    This object is achieved by an espresso machine with the features specified in claim 1.
    By combining the inclined stationary arrangement of the grinder to the brewing chamber in the filling position with the greater inclination of at least one of the Mahlwerkauslauf remote portion of the feeder channel down to the brewing chamber in filling position, it is achieved that the millbase always reliable during milling, without causing blockages in the feeder channel, which is fed to the open-topping brewing chamber and thus during the milling process falls smoothly from the end of the feeder channel into the brewing chamber.
    The tendency of the stationary grinder is so low that the supply of coffee beans in the grinder and the grinding function are not affected and the grinder can be compact installed in the espresso machine. A disturbance of the filling of the brewing chamber in filling position by clogging of the feeder channel is reliably avoided by the compared to the grinder stronger inclination of at least the remote from the Mahlwerkauslauf portion of the feeder channel down to the brewing chamber in the filling position.
    According to claim 2 of the grinder outlet remote section of the feeder channel is simply bent down from this.
    The inclination of the grinder or the tilt angle of the grinder is based on the vertical axis relative to the vertical and is according to claim 3 preferably between 5-35 °.
    The contrast stronger inclination of the removed or bent portion of the feeder channel is according to claim 4 preferably between 25-45 °, particularly preferably 35 ° relative to the horizontal.
    Particularly preferably, a tilt angle of the grinder of greater than 5 ° is combined with an angle of 35 ° of the remote portion of the feeder channel relative to the horizontal.
    The above-mentioned horizontal or the vertical refer to a properly established in the horizontal espresso machine, in which the grinder is fixed.
    According to claim 5, the above features of the tilted fixed arrangement of the grinder with the inclined relative to the horizontal training of the feeder channel or its remote from the Mahlwerkauslauf section are provided in an espresso maker, the brewing chamber in filling vertically under the feeder channel, in particular vertically below the remote from the grinder section of the feeder channel and can be pivoted away for the brewing process from this filling position to a position of the feeder channel or the grinder. The inventive modification of an espresso maker can therefore be carried out without major design effort.
    An embodiment of the invention will be explained below with reference to a drawing with a figure, from which illustrate the inventive features. Hereby shows:<Tb> FIG. 1 <SEP> a brewing unit with a brewing chamber and a brewing piston and a grinder, schematically and partially cut in a side view.
    In Fig. 1, a brewing unit 1 is shown with a brewing unit housing 2, in which an open-top brewing chamber 3 with a pivoting arm 5 about an axis 6 is pivotable. The brewing chamber 3 is shown in a filling position I with solid lines and cut. In a pivoted away from the filling position II position the brewing chamber shown in broken lines is prepared for a brewing process, to which they can be pushed in the direction of a non-designated straight double arrow up to a brewing piston 4 and on this.
    To the preceding filling the brewing chamber with ground coffee as ground material is in the espresso maker, in which the described brewing unit is installed, adjacent to the brewing unit a grinder 7 is arranged. The grinder comprises a drive motor 8, a grinding mill inlet 9 and a grinder outlet 10, to which a feeder channel 11 for feeding the ground material to the brewing chamber 3 in filling position I is attached.
    The fixed in the espresso maker automatic grinder 7 is, as shown in Fig. 1, arranged with its grinder vertical axis 13 with respect to a vertical 12 tilted by an angle of 10 °. The tilt angle can also be greater, at least 20 °, without differences in the grind and the distribution. The feeder channel 11 on the grinder outlet 10 initially runs at right angles to the vertical axis 13 of the grinder, whereby it is inclined by the same angle to a horizontal 16, as the vertical axis 13 to the vertical 12. However, the feeder channel 11 with its from the mill inlet 9th removed portion 11 further down to the brewing chamber 3 in the filling position, so that the distal portion extends at an angle of 35 ° to the horizontal 16.
    As a result of the inclinations of the grinder 7 and the removed portion of the feeder channel, the brewing chamber 3 is filled in the filling position I during the grinding process trouble-free with ground coffee, which is supplied through the tubular feeder channel. Subsequently, the filled brewing chamber can be pivoted away from the grinder 7 in the position II, from which further functional positions of the brewing chamber for the brewing process and subsequent operations can be taken conventionally.
