Definitions

the invention relates to a Schlauchaufrollsystem with an axis having a fluid line, with a seated on the axis and rotatable about this hub, which is equipped with a hose reel, on which a hose is wound, wherein the hub has a fluid line, wherein a guide a fluid through the fluid line in the axis towards the fluid line in the hub and in the connected hose interruptible possible and equipped therewith a cooking appliance.
Schlauchaufrollsysteme usually have a drum on which a hose is wound up.
the hose is connected at one end to a fluid delivery port on the drum.
the drum is supplied with a fluid, in particular water or water with a cleaning fluid or the like, forwarded within the drum to the fluid discharge port, transferred there into the tube and discharged again at the other end of the tube from a fluid outlet.
This fluid outlet can be provided with a shower.
Such Schlauchaufrollsysteme be used, inter alia, in connection with cooking appliances. With the fluid from the fluid outlet with the shower possibly connected, the interior of cooking appliances or other parts can be cleaned.
a Schlauchaufrollsystem offers when using in connection with cooking appliances compared to a conventionally suspended hose the advantage that when not in use, the hose neither disturbs the use of the cooking appliance nor the hose in the ground area comes into contact with dirt or otherwise damaged. Especially in professional kitchens and kitchen appliances, the hygiene guaranteed in this way and the minimization of the risk of stumbling when not using the hose are particularly advantageous.
a roll-up mechanism ensures that the tube, when not in use, is rolled up in one or more turns around the drum, thus taking up very little space and being in a defined location.
Such Schlauchholzrollsysteme with about a so-called roll shower device are expediently constructed so that only a fluid can be passed through the hose to the fluid outlet or the shower head when the hose is at least partially pulled out. In the rolled-up condition, however, the feed to the rolled-up tube should be blocked in order to avoid a continuous load at rest.
a mechanical valve can be used.
an automatic fluid barrier is used. This is especially in commercial kitchens a great advantage, since especially in cleaning tasks trainees or technically low-skilled forces are used, and therefore the relatively high risk that an improper operation of any manual shut-off valves, resulting in hazards and damage to the Can lead hoses.
Hose reeling systems are known with such automatic shut-off.
the shut-off takes place in a radial region of the drum or a hub, which is provided in the drum and to which the fluid is supplied. Because the shut-off takes place only within or within a plurality of individual angular sections on a radial region of this hub, there are alternately locked and unlocked regions during unwinding of the rolled-up tube.
the tube can be fixed in the (non-locked) fluid (angular) areas and thus ensures that the fluid also arrives at the fluid outlet.
a roll shower device for a cooking appliance in which an electric switch is actuated by the rotation of the drum. This switch in turn controls an electric solenoid valve.
the electric switch is positioned so that in the wound state of the hose, the solenoid valve shuts off the fluid supply. This too increases the complexity of the system. An additional power supply is needed for the operation of the showerhead device, which leads to additional costs.
a hose drum is used, in which water is supplied in the axis region. The water is stopped there by a valve assembly at rest. If a piece of hose is withdrawn from the drum beyond a predetermined minimum distance, then a spring element is withdrawn in the valve assembly by the rotation of the hose drum thereby taking place. By retracting the spring in the valve assembly, the path for the water is released to flow from the axis region of the hose reel into an adjoining and radially outwardly through the hose reel outport assembly and out of this then into the hose.
the object of the invention is in contrast to propose a Schlauchaufrollsystem that allows automatic shut-off for the supplied fluid and this is simple, inexpensive and reliable.
the invention provides a shut-off facility for rotary feedthroughs for fluids in reel systems for flexible hoses with a limited hose length.
the invention operates in that the hub of the drum is displaced in the axial direction during and by a rotation of the drum relative to the drum. So it's not just the usual rotational movement of the drum when winding or unrolling the hose but also a movement in the axial direction.
the fluid guide In the unrolled or partially unrolled state, by contrast, the fluid guide is no longer locked and the fluid can be controlled by the user by means of the manual valve at the end of the tube.
This displacement of the component in the axial direction is made so that the displacement direction is dependent on the direction of rotation.
the hub is displaced by its rotation with the drum so that, when the hose is rolled up, the hub is automatically and defined in an axial position in which the fluid guide is interrupted by the supply of fluid through the axle to the hub.
the hub according to the invention is axially displaced so that the fluid can now flow from the supply in the axis in the hub and then further into the hose ,
the hub When rolling up the hose on the hose reel, the hub is moved in the opposite direction by the now opposite direction of rotation of the drum. The hub is thus after reeling in the area in which the fluid supply is blocked from the supply in the axis to the hub.
a valve assembly is not retracted by a spring design and provides a path for a fluid, but is followed by an axial displacement of the hub relative to the axis as a whole.
a valve assembly is also possible to rotate the connection of the fluid line in the hub with the hose reel about the axis, and nevertheless ensure a perfect and reliable closure or an opening for the fluid by the axial displacement of the hub ,
the invention enables a simple, cost-effective, reliable and automatic fluid shut-off, which is also completely integrated in the hose reeling system.
the axial displacement is performed by a link on the axle and a guide member in the hub.
the gate preferably has a helical radial section, ie a spiral groove around the axis with a technically reasonable width and a pitch relative to the axial direction of the axle or the hub.
the scenery corresponds in this case about a thread.
the scenery has at least as many turns as the hose has turns on the hose reel.
the scenery can make a two-sided leadership possible, namely for the axial movement in both directions.
the hub and the scenery can be connected by means of a socket.
the hub can be manufactured cost-effectively with the slide if the bushing and a part of the hub facing away from the water-fluid supply are a common component, for example a cast part.
the scenery in the hub can be made so deep that the hub is not broken.
the scenery can also be arranged on the axis.
the guide element is radially placed the axial bore of the hub.
the embodiment can be designed without a hub bushing.
the hub in the rolled-up state of the hose has an axial position on the axis in which the supplied fluid can not get from the axis of relationship in the hub from the axis. This is achieved by the radial bore in the hub is outside the sealing area of the radial fluid supply of the axis.
provision may be made to provide sealing elements positioned further outboard. This prevents fluid from escaping uncontrollably through the hub and axle connection during the transition from the bore of the hub to the fluid guide when the hose is rewound onto the hose reel.
the gate can also be mounted on the axle and the guide pin attached to the hub.
the process is kinematically reversed.
the effect is basically similar to the first embodiments.
a Schlauchaufrollsystem is created, which is primarily intended for fluids such as water, but possibly also for cleaning agents or mixtures of water and detergent.
a gas such as air could be passed through the hose of Schlauchaufrollsystems.
the fluid is then guided to its destination and can be dispensed there targeted.
a hand-operated valve which allows or prevents the escape of the fluid.
the hose Due to the roll-up functionality, the hose is wound up after use.
hose reeling systems For applications related to cooking appliances hose reeling systems are useful, have the hose lengths of one or a few turns on the drum. In many cases, a hose length of 1 m to 3 m is sufficient.
the invention also relates to a cooking appliance provided with a hose reeling system according to the description and the claims.
a substantially fixed axis 10 is shown. Centrally through the axis 10 leads a fluid line 11, 12, which is formed in the concrete example predominantly of an axial bore 11. Through the axial bore 11 in the axis 10, a fluid (not shown) is supplied from the left from a water supply network, a fluid reservoir or other fluid source.
the axial bore 11 terminates in a radial bore 12.
This radial bore 12 leads from the axial bore 11 in one, two or more branches in different radial directions outwardly to the circumference of the axis 10.
the radial bore 12th is performed in the illustrated embodiment as running through the center of the axis 10 and thus the axial bore 11 cutting through bore. This is technically particularly practical and reliable.
the fluid line 11, 12 is composed by the axis 10 together.
a hub 20 in section On the right side of the hose reeling system in the FIG. 1 you can see a hub 20 in section.
This hub 20 is positioned on the axis 10 and rotatable relative to the fixed axis 10 about the axis 10.
the hub 20 is with a Drum firmly connected.
the drum is not shown separately in the figures.
a sliding bearing is provided between the axis 10 and the hub 20, a sliding bearing is provided.
the Schlauchholzrollsystem can be mounted.
the hub 20 of the drum has an axial bore with an inner diameter that largely corresponds to the outer diameter of the axle 10. The hub 20 can thus be placed on the axle 10 and rotate around the axle 10 as needed due to the sliding bearing.
the hub 20 carries a tube 21. Of the tube 21 is shown only a short piece, which is connected to a radial fluid connection device 23 of the hub 20.
the hose 21 itself is flexible as usual with hoses. He sticks out in the FIG. 1 up and out of the hub 20 to the outside (not shown) and can be placed around the hose reel in several turns.
a fluid leading line can be arbitrarily passed through the room (compare the position in the FIG. 2 ).
a fluid outlet opening 25 is provided, with which a user with unrolled hose 21 exiting fluid can steer in a desired direction.
a shower (not shown) with or without adjustable elements for achieving a desired output beam.
the axle 10 protrudes into the hub 20 up to a certain stop.
the axle 10 on the right side practically exits the hub 20 again.
the radial bore 12 ends in the illustration in the FIG. 1 on a tubular inner wall of a shaft 10 receiving nozzle 24 of the hub 20th
the nozzle 24 thus extends in the direction of the water supply to the axial bore 11 of the hub 20 about the axis 10th
the axis 10 carries in the illustrated embodiment, outside a plurality of circumferential sealing elements 15 which act against the inner wall of the nozzle 24 of the hub 20.
the radial or transverse bore 12 terminates in a region between the circumferential sealing elements 15 on the circumference of the axis 10. Fluid, which is supplied in the axial bore 11 through the axis 10 to the radial bore 12, thus can not escape from the radial bore 12, because it is prevented by the inner wall of the nozzle 24. As far as it passes in a small amount in an annular gap 19 between the axis 10 and the hub 20, it is stopped laterally in the axial direction of the sealing elements 15.
the hub 20 of the drum has a radial bore 22.
the radial bore 22 extends from the inner wall of the hub 20 adjacent to the axis 10 to the fluid connection device 23 to which the hose 21 is connected.
FIG. 2 is another position of Schlauchaufrollsystems shown.
the tube 21 was unwound from the drum of the hub 20, not shown.
the hub 20 has rotated radially. It has been assumed in the representation that the hub 20 four turns from the FIG. 1 has performed on the axis 10, as will be explained in more detail below.
FIGS. 1 and 2 A major difference of positions from the FIGS. 1 and 2 is that the axis 10 has shifted axially within the hub 20 axially to the right. In practice, the hub 20 will have shifted to the left on the axis 10, which is synonymous. Essential is the relative displacement in the axial direction of the axis 10 and hub 20th
the radial bore 12 of the axle 10 has now come close to the radial bore 22 of the hub 20.
the sealing elements 15, which are circumferentially arranged on the circumference of the axis 10, are also axially displaced so that now the outlet of the radial bore 12 at the periphery of the axis 10 between the sealing elements 15 in an axial region, in which also the radial bore 22 of the hub 20 ends on the inner wall.
the diameter of the axis 10 is slightly smaller than the inner diameter of the nozzle 24 of the hub 20 in the region between the two illustrated sealing elements 15.
the guide member 26 protrudes into the groove of the link 16.
the angle ⁇ of the spiral groove of the link 16 relative to the axis 10 determines the exact relationship between the extent of the axial displacement of the hub 20 to axis 10 on the one hand and the rotation of the hub 20 about the axis 10 on the other hand, namely by the slope of the spiral backdrop , For tribological reasons, one will prefer an angle ⁇ of more than 45 °.
the axial movement need only bridge relatively small and relative to the length of the unrolled tube 21 small dimensions to bring the radial bore 22 in the hub 20 into engagement or out of engagement in the annular gap 19 between the sealing elements 15 and so to stop the flow of fluid.
the annular gap 19 between the two adjacent sealing elements 15 has a finite width which corresponds approximately to the order of magnitude of the axial dimension of the link 16. This has the consequence that a fluid flow from the radial bore 12 into the radial bore 22 takes place not only at an exact coverage of these two holes, but also over a well-defined range of axial displacement of these two holes 12, 22 to each other, as can be seen in of the FIG. 2 can recognize well.
the sealing elements 15 also prevent fluid from the annular gap 19 from escaping from the annular gap 19 in the axial direction.
the sealing elements 15 are preferably O-rings. In a preferred and also in the FIGS. 1 and 2 illustrated embodiment, a total of four sealing elements in the form of such O-rings are shown, each in the outside sitting corresponding circumferential grooves of the axis 10. The two most important and inner sealing elements 15 are placed next to the annular gap 19 or on the axis in front of and behind the outlet of the radial bore 12 from the axis 10 at its periphery.
a third sealing element 15 in the form of, for example, an O-ring on in the FIGS. 1 and 2 right side of these two inner sealing elements 15 ensures that the outlet of the radial bore 22 is sealed from the hub 20 when the fluid guide is just interrupted. In this way, it is reliably avoided that, for example, fluid returning from the hose 21 into the hose reel system may inadvertently be distributed along the axis and impair its functioning over time.
a fourth sealing element 15 on the exactly axially opposite left side of the two inner sealing elements 15 contributes to the additional sealing in order to secure the area against fluid from the outside and thus guarantee an absolutely hygienic separation of the different fluids from each other.
the interruption of the fluid guide it is not mandatory.
the hose 21 can be automatically rewound by the spring force after unwinding against the spring force.
a mechanical end stop it is possible to prevent the hand-operated valve from being wound too far onto the drum of the hub 20 by the spring. This position would then be called wound position again.
