Definitions

  • the present invention relates to a device for actuating a valve which is connected to a removable water container of a hot beverage preparation device, namely at an interface between a basic unit, so the preparation device without water tank, and the water tank and / or at an interface between a Aufbrüh adopted and a beverage container Hot beverage preparation device is arranged.
  • the valve comprises a valve housing and a movably mounted therein, acted upon by a spring force valve body. It serves to open and close a drain opening on the water tank or the Aufbrüh coupled.
  • Such valves are provided when the user is at risk of scalding.
  • coffee makers will be discussed hereinafter instead of hot beverage preparation devices.
  • Similar versions of such a valve are known in principle as a so-called drip stop, for example in coffee machines.
  • the valve is located between a filter holder and a coffee pot. If the coffee pot is to be filled below the filter, the valve is open. As soon as the coffee pot is removed, the valve closes automatically and prevents the coffee from dripping. This function is impaired, for example, by lime or coffee deposits, in particular in the region of the valve seat. This can cause the valve to no longer close tightly. This generally happens with all liquids that tend to form deposits.
  • Object of the present invention is therefore to provide an improved valve assembly that reliably prevents dripping.
  • the device according to the invention has an actuator for actuating the valve, which causes a movement of the valve body against the spring force.
  • the opening force is defined by the operating force.
  • Their maximum amount is determined by the force that can be demanded from an operator to place the pot under the filter holder, inter alia, in terms of comfort maximum. Since the opening force opposes the closing force, the closing force is smaller or at best as large as the opening force. To close the valve is therefore also only a limited force available.
  • the invention turns away from this concept. Rather, it pursues the principle of providing the opening force, at least in terms of its size, largely independently of the operator, by means of an actuator. As a result, the opening and the closing force of the valve can not only be matched exactly. Rather, now in particular the closing force can be dimensioned independently of a narrow operating force. As a result, the closing force provided by the spring can be dimensioned exclusively according to how the shooting of the valve is reliably ensured even with deposits. It can therefore be considerably larger than before.
  • a comparable device can be arranged on a removable water tank.
  • Both the valve at the outlet of the Aufbrühaji and the water tank can each be assigned its own actuator.
  • both valves can be actuated by a common actuator. Regardless of which container the signal to close to the actuator, he closes both valves.
  • this offers the advantage that, when the beverage container is removed, the valve at the brewing device is not only closed in a known manner. At the same time the actuator also closes the valve on the water tank and thus prevents a further inflow of hot water in the Aufbrüh sensory. The brewing process is interrupted so that the brewing device can not overflow.
  • the actuator or the actuators can be arranged both on the base unit and on the water tank. At the water tank he can valve directly actuate. This leads to a compact design and avoids energy losses through short transmission paths. If the actuator is arranged on the basic unit, a container with a low dead weight is obtained. In addition, the interfaces between the water tank and the basic unit and the interface between the actuator and the valve coincide. When removing the container from the base unit, the power flow between the actuator and the valve body is interrupted. Thereupon, the preloaded spring arranged on the valve can close the valve automatically.
  • the actuator can be operated either with mechanical or electrical energy, with respect to the
  • Beverage container only with electrical energy.
  • the mechanical energy can continue to be provided by an operator available, but now by means of a
  • the gearbox is part of the actuator.
  • Energy can activate the actuator, for example an electric motor, completely independently of the operating force. It can basically be made available from the basic unit, but also from the water tank. Preferably, the actuator, for example an electric motor, completely independently of the operating force. It can basically be made available from the basic unit, but also from the water tank. Preferably, the actuator, for example an electric motor, completely independently of the operating force.

  • An electrical power supply from the water tank means that it can be equipped with its own power supply. It offers the advantage that the water tank can then be operated independently of the base unit as a separate kettle.
  • the actuator may be, for example, an electromagnet or an electric motor. If the actuator is an electromagnet, its movably mounted armature can be indirectly connected, for example via a transmission, or directly to the valve body. The anchor may also be part of the valve body itself. Then, the actuator is arranged in the water tank as close to the valve to avoid additional transmission elements between the actuator and the valve body with corresponding friction losses. If the actuator is an electric motor, a gear can be arranged between the electric motor and the valve body, which converts the rotational movement of the electric motor into a straight-line movement of the valve body. As a gear come for example eccentric, helical, crank or traction mechanism into consideration.
  • a power supply of the actuator from the base unit in any case the transmission of either mechanical or electrical energy at an interface between the basic unit and water tank required.
  • means for transmitting energy are arranged at the interface. These means are designed so that they are coupled only with attached container and transmit energy. Once the container is removed, there is an interruption of the power supply. The actuator then lacks the necessary energy to apply a counterforce to the closing force of the closing spring, and the closing spring closes the valve in the same way as in devices without an actuator.
  • mechanically effective means such as pins, plungers, joints or springs, can be used, which can transmit an actuating force to the valve.
  • the means may be electrically conductive, for example pin-shaped or annular contact elements, which come into contact with each other when the containers are placed, thus closing an electrical circuit. When removing the container they are disconnected, which leads to the interruption of the power supply of the actuator with the consequences already mentioned.
  • a contact element arranged regularly on the container in the bottom area of the container can therefore be used, which is in operative connection with a mating contact element on the base unit.
  • a plunger or a ring can come into contact with a ring as a mating contact element as contact elements.
  • the arrangement of a ring as one of the contact elements - at least in centric arrangement of the interface on the container - has the advantage that the container with respect to a vertical axis of rotation in any orientation can be placed on the coffee machine.
