Definitions

  • the invention relates to a container for storing liquids and a device for removing the liquids from this container for further use, in particular a water storage container in an automatic beverage dispenser and a water extraction device, the container having a plug-in connection part in the bottom area which includes a valve and which connects to a Footprint of integrated plug-in connection part, via which the stored liquid can be passed on, can be connected for liquid removal.
  • vending machines that produce soft drinks from one or more beverage concentrates and carbonated water can obtain the water required for beverage production directly from a water pipe connected to the vending machine.
  • vending machines can be supplied with water from a storage container, for example in cases in which a water pipe is not available at the location of the vending machine if the quality of the water that can be drawn from the water pipe does not meet the special requirements for the beverage to be produced.
  • trouble-free operation depends on the fact that sufficient quantities of the starting materials can be removed from the storage container during each manufacturing process.
  • the invention has for its object to provide a storage container with a removal device of the type mentioned, which enables trouble-free operation with a decreasing supply of the liquid stored in the container.
  • the invention is characterized by a number of advantages.
  • the containers of the vending machines only have a plug-in valve and an electrical switch.
  • the switch is used to switch off the vending machine when the amount of liquid in the container reaches a critical value.
  • Both components, valve and switch are common products that can be adopted without special adaptation. They work together in a simple manner and ensure trouble-free operation.
  • the container is detachably connected to the vending machine, so that the container can be easily removed from the vending machine and refilled with the liquid to be stored in each case.
  • An advantageous embodiment of the invention is characterized in that the container has on its underside an adjustable foot which acts on the switch contact piece of the switch.
  • the pen concentrates the pressure emanating from the container including the amount of liquid contained in each case onto a punctiform area at the pen tip pointing downwards and thus transmits the pressure in a defined manner.
  • the vending machine has a sealing membrane with a plunger in the area of the pin, which transmits the pressure emanating from the pin to the switch contact piece.
  • This embodiment is characterized by a double protection; the interior is protected from contamination by means of the sealing membrane and the switch contact piece of the electrical switch is protected from otherwise possible damage by the pin when the container is placed on the vending machine.
  • the switch is designed as a snap switch.
  • the switch thus moves the container only when a certain filling level is reached and thus when a critical pressure value is reached, while the position of the container is not changed before this point in time when the amount of liquid is reduced.
  • the snap switch thus gives the reservoir Stability. Fluctuations in the liquid in the container and the container itself do not affect the interaction between the container and the beverage dispenser.
  • the container interior is flat on its underside in such a way that the surface lowers from the area of the pin to the area of the valve. This configuration of the container supports the pivoting of the container about the pivot point in the valve.
  • a further advantageous embodiment of the invention is characterized in that the switch has a second switch position which the switch contact piece produces when a predetermined second container pressure is reached. The switch then triggers an alarm message in its first switch position, which indicates the end of the supply in the container, while in the second switch position the drinks machine is switched off.
  • Figure 1 shows a container 1 for storing water for use in a vending machine.
  • the container 1 is placed on a shelf 3 in the vending machine and is thus connected to the vending machine.
  • the container 1 is preferably cuboid and can be closed by a removable cover 12.
  • the liquid stored in the container 1 reaches the beverage dispenser 3 through a plug connection containing a valve 2.
  • This plug connection containing the valve 2 which is described in more detail with reference to FIG. 2, consists of two parts 21 and 22 which can be plugged into one another.
  • a first valve part 21 is arranged on the underside of the container 1 and a second valve part 22 is arranged in the shelf 3 in the vending machine.
  • the valve 2 is opened by inserting the container 1 and closed by detaching the container 1.
  • the plug connection is designed as a pivot bearing and is arranged offset to the pivot line of the filled container 1, so that the container 1 is pivotably mounted with respect to its vertical axis with respect to the footprint 3.
  • an electrical switch 4 with respect to the pivoting line of the container 1 relative to the plug connection.
  • this has a switch contact piece which can be moved upwards (in the direction of the container 1) or downwards 42, which is mechanically connected to a return spring 41 on its underside.
  • the container 1 which is pivotably mounted in the plug-in connection, presses on this switching contact piece.
  • the return spring 41 presses the switching contact piece 42 and the container 1 upwards. The container 1 thus pivots about the pivot point in the connector.
  • the spring 41 presses the switch contact piece 42 of the switch 4 into a first switch position, that is to say closes the electrical switch 4.
  • the closing of the switch 4 is intended to end the operation of the drinks machine and / or trigger an alarm message. This can be done, for example, by means of a relay, not shown in the drawing, which is connected in series with the electrical unit (s) of the beverage machine.
  • a second switch position can be realized in which the beverage machine is switched off.
  • an alarm message can be triggered, which indicates the end of the supply in container 1.
  • the container 1 has in particular an adjustable foot 11 on its underside, which acts on the switch contact piece 42.
  • the length of the adjusting foot 11 is dimensioned in relation to the valve part 21 arranged on the underside of the container and possibly further adjusting feet or supports 13 on the underside of the container so that the container 1 detached from the vending machine 3 can be safely placed on a flat surface.
  • the standing surface 3 has a sealing membrane 31 with a plunger 32, which transmits the pressure emanating from the adjusting foot 11 to the switching contact piece 42.
  • the switch 4 is preferably designed as a snap switch in order to give the container 1 stability to fluctuations in the liquid in the period before the critical pressure value or values are reached.
  • the container interior is flat on its underside in such a way that the surface in the area of the adjustable foot 11 lowers to the area of the plug connection with the valve 2.
  • the plug-in connection 2 between the storage container 1 and the shelf area 3 is shown in a practical embodiment in FIG. 2.
  • the plug-in connection elements are designed essentially rotationally symmetrical. It can be seen that is formed on the footprint 3 to form its connector 22 as a pipe socket.
  • a plug connection part 21 projects into the floor there of the reservoir 1 molded pipe socket.
  • a valve tappet 25 which can be lifted upward against the force of a spring 23, is arranged from a valve opening 24.
  • An insert 26 is arranged in the plug-in connection part 22 assigned to the footprint 3 in such a way that a dome-shaped bracket 27, when the storage container 1 is placed on the footprint and engage in the two plug-in connection parts 21 and 22, the valve tappet 25 is lifted upwards and thereby the Valve opening 24 is opened so that the water stored in the storage container 1 can get down into the area of the insert 26, from where it is derived for further use or is sucked off by a feed pump.
  • An elastic sealing element 28 seals the two plug connection parts 21 and 22 against one another. The design of this sealing element 28 increases the sealing effect due to the water pressure occurring in this area.
  • the upper edge of the plug connection part assigned to the shelf 3 is closed with an annular cap 29 made of elastic material.
  • the reservoir 1 could be supported on this annular cap 29 with respect to the standing surface 3, so that an elastic pivot axis would be formed in this area. In this case, the foot 13 of the storage container 1 should not touch the footprint 3.
  • this adjusting foot 13 of the storage container stands on the support surface 3, so that the pivot axis for the storage container 1 is formed at the point of contact.
  • the plug connection 2 located in the vicinity experiences only extremely little for its function due to the tilting movement of the storage container insignificant relative movements against each other. In this case, the bottom region of the storage container 1 is not supported or is hardly supported on the annular cap 29 of the plug connector 22.
  • this storage container 1 On the opposite side of the storage container 1 with respect to the center of gravity of the storage container 1 of the plug-in connection 2, this storage container 1 is always supported laterally from the elastic membrane directly on the storage surface 3 via the adjusting foot with a water-filled state.
  • the leveling foot 11 extends - like the leveling foot 13 - in the direction of the top view of FIG. 2 in a strip shape below the storage container 1, specifically beyond the opening of the leveling area 3 covered by the sealing membrane 31. Only when the storage container 1 is substantially emptied is a spring element of the switch 4 able to raise the correspondingly emptied storage container 1 via its adjusting foot 11, as a result of which an electrical switching function is also carried out, which is evaluated via the connecting lines 41 and 42 .
