Definitions

  • the present invention relates to a hose device and an arrangement with a water-conducting household appliance and a hose device of this type.
  • Household appliances that carry water are usually connected to a water supply network with the aid of a hose device in order to supply them with fresh water. It is common to do so, such as the EP 2 314 752 A1 shows that such hose devices are provided as double-walled systems with an inner and outer hose. The annular space formed between the inner and outer hose is connected in a fluid-conducting manner to a sensor in the base of the household appliance. It can therefore detect a leak of water from the inner tube into the annulus. Such hose devices also have a blocking device which is designed to block a water supply to the inner hose in the event of a detected leak.
  • a disadvantage of hose devices in EP 2 314 752 A1 described type is that they have a comparatively complex structure and are correspondingly complex and costly to manufacture.
  • the EP 0 819 918 A2 Figure 12 shows a fluid control system in which a control device is provided for closing a fluid passage in order to achieve pressure regulation, the control device being intended to be integrated or used in a line which is part of a hydraulic device.
  • an inner hose that conducts fresh water should be suitable for drinking water, as special hygiene requirements must be observed. Such requirements can result from legal regulations and are subject to corresponding change. As a result, the choice of material for hoses that conduct fresh water can be restricted. Furthermore, this can have the consequence that hose materials are used which have a reduced strength.
  • a hose device for a water-carrying household appliance with a first connection for a connection to a water supply network, a second connection for a connection to the household appliance, precisely one hose, which is arranged between the first connection and the second connection, the hose is designed as a single-walled corrugated hose and is set up to supply water to the household appliance, and a pressure reducer which is set up to reduce pressure surges from the water supply network into the corrugated hose.
  • the hose device has only a single (that is, not about double-walled hose or two, three or more hoses) hose, a simple and inexpensive hose device can be provided.
  • no hose - in particular neither corrugated nor smooth hose - is provided between the first and second connection.
  • the pressure reducer is arranged in front of the corrugated hose in the direction of flow. The probability of a leak is therefore greatly reduced, so that no additional external hose is necessary to catch the leakage liquid.
  • Such pressure reducers are not known from the prior art in this context. This differs from so-called flow reducers, such as in EP 2 314 752 A1 described, whose only task is to reduce the flow during operation to a certain volume flow. However, these are not able to reduce high pressure surges in the pipeline network to a level that avoids leaks in the corrugated hose.
  • the water-carrying household appliance is, for example, a household dishwasher or household washing machine.
  • the water supply network includes, for example, a tap with an external thread and provides water with a nominal pressure of, for example, 3 to 7 bar, in particular 5 or 6 bar.
  • the first connection comprises, for example, a nut with an internal thread for screwing onto the external thread of the tap.
  • the first connection comprises a connector on which the nut is rotatably mounted.
  • the connector can comprise, for example, a connecting section which protrudes into a first connecting section of the corrugated hose and is connected to it.
  • the first connection can comprise a sieve for filtering water.
  • the second connection comprises a connector and a nut rotatably mounted on the connector with an internal thread for screwing onto a connection element of the domestic appliance with an external thread.
  • the connector of the second connection can include a curved section, in particular by 90 °, in order to enable a space-saving connection to the household appliance, since the connection element of the household appliance together with the household appliance can be arranged correspondingly closer to a wall.
  • the connector of the second connection comprises a connecting section which, for example, protrudes into a second connecting section of the corrugated hose and is connected to it.
  • a “single-walled hose” means a hose which comprises a simple wall and is in particular formed in one piece, in one piece or in one piece of material.
  • “Corrugated hose” means in the present case a hose that comprises wave crests and wave troughs which alternate along a direction of extent of the corrugated hose.
  • the first and / or the second connection section can be smooth (that is, not corrugated) or corrugated in sections.
  • the corrugated hose is designed as a water-carrying corrugated hose.
  • the corrugated hose is set up to conduct or conduct water on its corrugated inside.
  • a corrugated outside of the corrugated hose is set up to delimit the corrugated hose and any water located therein from the surroundings of the household appliance.
  • a corrugated outside of the corrugated hose faces an environment of the household appliance or an external environment.
  • the outer surface of the corrugated hose forms part of an outermost surface of the hose device. In the case of a hole in the corrugated hose, the fresh water would thus get into the vicinity of the household appliance, in particular on the floor of a building.
  • Corrugated hoses have the advantage that they can be bent more easily and that damage due to kinks rarely occurs.
  • the corrugated hose creates a fluid connection between the first connection and the second connection.
  • the pressure reducer is a device which, in particular, effectively dampens pressure surges from the pipe network, so that the corrugated hose is protected. Furthermore, the pressure reducer is set up, for example, to abruptly reduce a flow cross-section when a pressure surge occurs in the water supply network, in order to reduce the pressure surge in the corrugated hose.
  • the pressure reducer is set up to reduce a pressure of a pressure surge in the corrugated hose to below 50%, 40% or 30% of the To reduce the pressure of the corresponding pressure surge in the water supply network and / or to reduce a pressure of a pressure surge in the corrugated hose to below 15, 12, 10, 8 or 6 bar.
  • the corrugated hose can be manufactured with a correspondingly reduced wall thickness.
  • the hose device between the first connection and the corrugated hose is designed without a safety valve for shutting off a flow of water into the corrugated hose in the event of a leak from the latter.
  • the hose device does not include a safety device with a safety valve for shutting off the flow of water. In this way, a particularly inexpensive and yet reliable hose device can be provided.
  • the pressure reducer comprises a control element which is set up to reduce a flow cross section for reducing pressure surges in the corrugated hose by means of an elastic movement and / or axial movement.
  • the pressure reducer is arranged, for example, inside the first connection.
  • the elastic movement and / or axial movement is triggered by means of the pressure output.
  • a mass flow and thereby the pressure can be suddenly reduced.
  • the pressure reducer is set up to form a plurality of radial channels by means of the elastic and / or axial movement when the pressure surge occurs in the water supply network and thereby to reduce the pressure surge in the corrugated hose.
  • the radial channels by means of the elastic movement or elastic deformation.
  • control element comprises a disc which is designed to be elastically deformable.
  • the disk is made, for example, partially or completely from silicone and / or from an elastomer material.
  • silicone and / or an elastomer material is well suited for drinking water or drinking water approval.
  • the disk comprises a flat and ring-shaped side against which fresh water flows, so that an elastic deformation and / or an axial movement of the disk takes place.
  • the pressure reducer comprises inner and outer openings for the passage of water to the corrugated hose.
  • the regulating element is preferably set up to merely reduce and / or prevent a flow of water through the outer openings in order to reduce pressure surges in the corrugated hose.
  • the pressure reducer comprises a disk section and a tube section molded onto the disk section.
  • a fluid channel which is axially delimited by a wall of the disk section, is preferably formed within the tube section and the disk section.
  • the wall here comprises the inner openings which are arranged radially inside the fluid channel.
  • the disk section comprises a disk wall which is arranged radially outside of the tube section and which comprises the outer openings.
  • control element is provided so that it can move elastically with respect to the pane wall and is arranged on the pipe section opposite the pane wall.
  • the regulating element is designed to be pressed against the pane wall in order to at least partially close the outer openings close.
  • the pressure reducer is provided in the first connection, for example, in such a way that the water from the water supply network has to flow through the inner and / or outer openings in order to get into the corrugated hose. As a result, the control element is forced by the water, so that the function of the pressure reducer is always guaranteed.
  • the pressure reducer is screwed into the first connection by means of a thread.
  • an external thread is provided in an outer region of the disk section, which can be screwed into an internal thread which is provided within the first connection. This ensures a simple and reliable connection between the pressure reducer and the first connection.
  • the corrugated hose is made partially or completely from polyethylene.
  • the polyethylene is designed as cross-linked polyethylene (PE-X).
  • PE-X cross-linked polyethylene
  • Polyethylene is particularly suitable for use in drinking water.
  • the corrugated hose can thereby be manufactured inexpensively.
  • the strength disadvantages of polyethylene can be accepted because the pressure reducer is used.
  • the first connection is, in particular exclusively, connected to the corrugated hose by means of a plug-in connection and / or a non-positive connection, in particular cold-pressed.

  • the non-positive connection is formed, for example, by the radial force due to the resetting behavior of the connecting section of the corrugated hose on the connecting section of the connector, so that an axial fixation is ensured in particular due to friction (referred to here as "cold pressing").
  • the plug connection is preferably set up to withstand water pressures that are greater than 10, 12 or 15 bar.
  • the first connection comprises an inlet cross-sectional area for a water inlet and an outlet cross-sectional area for a water outlet, the inlet cross-sectional area being at least 9, 12, 15 or 20 times larger than the outlet cross-sectional area.
