Definitions

  • the present invention relates to a pad coffee machine with a heater for heating water, a brewing chamber for receiving a coffee pad and a hot water line connecting the heating device and the brewing chamber.
  • Pad coffee machines usually comprise a brewing chamber, at whose outlet opening a small nozzle is arranged; she serves the crema education.
  • the nozzle opening is often in the range of one millimeter or less.
  • the nozzle opening can be clogged by particles, such as regrind from the Päd or lime particles from the heater, and thus the functioning of the coffee maker can be affected.
  • a taper which can be configured as a nozzle, is also located downstream of a grinding stock holder in this device as well. So that the nozzle is not clogged by regrind, the upstream grist holder is provided with an inlet filter and an outlet filter. The pores of the filters are adapted to the size of the ground material and correspondingly smaller than the opening of the nozzle. With regard to the lime particles entrained by the brewing water, the device has no restraint systems. Thus, at least when decalcifying the device to blockage of the nozzle by lime particles and thus cause malfunction.
  • Object of the present invention is to avoid malfunctions due to blockages in pad coffee machines.
  • the device In order for the device to be able to retain the lime particles, it has passage openings, which of course are smaller than the particles.
  • the opening dimension is based on the nozzle cross-section. Because the device only has to hold back particles that can not pass through the nozzle.
  • a device for example, a sieve, a grid or a filter can be used.
  • the shape of the through holes may be circular or polygonal.
  • the edge of the openings may have a conical or rounded shape in the flow direction. This offers the advantage that the particles only contact the opening edges at certain points. With decreasing flow, the particles are only loose on the device and can possibly move away from it again. Clogging of the openings can be avoided over a longer period of time.
  • the location of the device in the flow path between the heater and brewing range is freely selectable.
  • the device can generally be positioned directly in front of the brewing area, in the course of the hot water line or directly on the heating device.
  • the brewing area begins downstream of a regularly arranged hot water distributor.
  • the device can be arranged, for example, in the region of a hot water inlet or upstream of a hot water distributor in the brewing chamber.
  • the arrangement at or near the brewing area causes a compact construction of the brewing chamber.
  • the device can be easily replaced because it is directly accessible with or after disassembly of the easily removable pad holder on Brühbibkopf without moreover, the case of the coffee maker must be opened.
  • the device may be formed as part of the hot water line, without being part of the brewing chamber or the heating device.
  • the device can be used as a separate replaceable module at any point between two pipe or hose ends of the hot water pipe.
  • the device is suitable for retrofitting as well as for use in different machine types.
  • the device when the device is arranged so that the water is conveyed against the direction of gravity, ie from bottom to top through the device is particularly advantageous.
  • the depressed by the flow against the device particles can be so with decreasing flow or in the flow-free state, only the
  • Openings of the device are largely avoided.
  • the device thus largely cleans itself automatically.
  • the device extends transversely or perpendicular to the flow direction and is thus also perpendicular to the direction of gravity.
  • the particles then dissolve most easily from the device. But it can also be curved or formed inclined with respect to the flow direction of the water.
  • the device may be arranged in a chamber formed by walls, which has a settling space for the particles.
  • the settling space can preferably be arranged in the immediate vicinity of the device.
  • the particles are, as already said, transported by means of the flow to the device and pressed to the device, so retained. With decreasing flow or in the flow-free state, the particles can then detach from the device and slide with appropriate inclination of the device in the settling space. This offers the advantage that the particles can not settle uncontrollably in the water pipe.
  • the settling space can be arranged in the flow direction below the device, so that the particles fall into the settling space due to their gravitational force. The particles can thus fall directly and in a short path into the settling space and collect there away from the device. Particles already collected in the settling chamber should not be dragged along again by the flow and load the device repeatedly.
  • the settling space is therefore arranged in a flow-calmed or flow-free region. It is formed in a section of the chamber, which is not directly flowed through by water, but in which, if appropriate, a flow shadow is generated. Once collected in such a settling space particles remain effectively retained therein until the chamber is cleaned or replaced.
  • the device and / or the chamber may be conveniently removable from the pad coffee machine.
  • it is positioned on or in the vicinity of already accessible or easily removable parts.
  • the brewing chamber top is easily accessible, for example, as soon as the pod holder has been removed.
  • the device z. B. be accessible via an easily removable housing cover.
  • the walls of the chamber delimiting the settling chamber can be provided with a surface structure which at least makes adhesion of the particles more difficult. This makes it easier to remove the particles in the event of cleaning, for example by simply rinsing out the chamber.
  • the surface of the device can also be dimensioned correspondingly large, so that it does not become clogged over the entire service life of the device and always ensures the necessary flow. So such a device does not need to be interchangeable and therefore not accessible.
  • the settling space can be sized accordingly, so that during the life of the pad coffee machine emptying is not necessary. Its volume is dimensioned so large that the total amount of particulate matter can reliably be absorbed even in very calcareous water.

  • a circumferential sealing lip 25 is formed, which seals the lower part 14 with the upper part when the brewing chamber 10 is closed.
  • the lower part 14 forms an adapted to the respective pad shape, only schematically illustrated interior 26, the funnel-shaped opening into a tubular drain opening 28.
  • the drain opening 28 contains a nozzle 30 inside.
  • the water inlet pipe 16 forms a free end 32 for connection of a hot water line, not shown, for example, a hose.
  • the arrows A the flow direction of the hot water is shown, which supplies a heating device via the hot water line of the brewing chamber 10.
  • the water flows through the water inlet nozzle 16 in the upper part 12 of the brewing chamber 10, passes through the sieve device 20 and flows through the openings 24 of the hot water distributor 22 in the an interior space 26 (not shown) of the bottom part 14.
  • the water is under pressure, which presses it through the coffee pad and as a coffee extract into the drain opening 28. Through the nozzle 30, the extract leaves the brewing chamber 10 in the direction of a vessel parked below it.
  • the screen 20 has the function of retaining particles carried in the water, for example lime particles, even before the brewing chamber 10. It ensures that the particles do not clog the openings 24 of the hot water manifold 22, let alone the nozzle 30. Its arrangement between heating device and brewing area thus prevents particles from ever reaching this area.
  • FIG. 2 shows a further embodiment of a brewing chamber 110 having an upper part 12, a lower part 14 and a disk-shaped hot water distributor 122 arranged therebetween.
  • the upper part 12 has a screen chamber 134 between a water inlet connection 16 and a water inlet opening 18.

  • the water inlet nozzle 1 16 is laterally formed on the screen chamber 134.
  • the brewing chamber 10 like the brewing chamber 10 known from FIG. 1, has a sealing lip 125 and a discharge opening 128 with a nozzle 130.
  • the arrows A 'in FIG. 2 show the direction of flow of the hot water through the brewing chamber 110.
  • the water flows through the water inlet nozzle 116 horizontally into the screen chamber 134. From there it is pressed against the force of gravity through the sieve 120. Entrained particles are first pressed by the flow against the sieve 120. With decreasing water pressure they sink
  • FIG. 3 shows a sieving module 200, which predominantly flows through horizontally, with a sieve 220 and a substantially horizontal settling space 236.
  • To the sieve module 200 are water inlet nozzle 216, 217, each with a free end 232, 233 formed. They are suitable for connection to a hot water pipe.
  • the sieve module 200 can thus be used at any point in a horizontally extending hot water line between a heater and a brewing chamber. This makes it suitable for retrofitting.
  • the directional arrows B in FIG. 3 indicate the direction of flow of the water through the sieve module 200.
  • the water flows substantially horizontally through the water inlet nozzle 216 into a screen chamber 234. From there it is forced against the force of gravity through the sieve 220 into the water outlet connection 217.
  • the particles retained by the sieve 220 may sink into the settling space 236 as the water pressure decreases, counter to the flow direction of gravity.
  • the settling space 236 is located here away from the flow, that is, it is not completely in the flow path of the water. As a result, already settled particles are not entrained again by a renewed flow.
  • the screen chamber 234 thus ensures that the screen 220 is not added by particles during operation.

  • a sieve module 300 In addition to water entry stub 316, 317, each with a free end 332, 333, it has a mainly vertically extended screen chamber 334 with a relative to the vertical inclined screen 320. Due to the inclination of the screen 320 it receives a larger flow area than if it were arranged horizontally in the screen chamber 334. In addition, the particles can be easier to solve in the inclined position of the sieve.
  • the sieve chamber 334 forms a settling space 336.
  • the arrows B ' indicate the direction of flow of the water through the sieve module 300. Also in the embodiment according to FIG. 4, it is conveyed against the force of gravity through the sieve 320 in the direction of the brewing chamber. Particles entrained with the water are retained by the screen 320 and sink back into the settling space 336 in accordance with their gravity.
  • the settling chamber 336 is arranged offset next to and opposite to a water inlet opening 315 down. He thus forms a completely flow-free space below the sieve 320. Once deposited particles can no longer be entrained by a subsequent flow and pressed against the screen 320. Furthermore The water in the area of the sieve chamber 334 follows a bent flow path. It prevents the particles from falling back into the hot water pipe.
  • the modular design of the sieve module 300 facilitates its replacement in case of repair. Such a case may occur, for example, when the settling space 336 is filled with particles and there is a risk that particles may clog the screen 320.
  • brewing chambers 10 and 110 can be modified in a customary manner by a person skilled in the art to a great extent without departing from the scope of the invention.
  • the concrete configurations of the sieve modules 200 and 300 can also take place in a different form from that described here.
  • the Absetzschreib 136, 236 and 336 can be configured in a different form, if this is necessary for space or designerischen reasons.
  • the use of the indefinite article "on” or "one” does not exclude that the characteristics in question may also be present multiple times.
