Definitions

  • the present invention relates to a hose device and an arrangement with a water-conducting household appliance and such a hose device.
  • Water-bearing household appliances such as household dishwashers, are usually connected by means of a hose device to a water pipe network to supply this fresh water.
  • hose devices are provided as a double-walled systems with an inner and outer tube.
  • the annular space formed between the inner and outer tube is fluidly connected to a sensor in the bottom of the household appliance. He can therefore detect a leakage of water from the inner tube in the annulus.
  • hose devices have a locking device which is adapted to block a water supply to the inner tube in the event of a detected leakage.
  • a disadvantage of hose devices of in EP 2 314 752 A1 described type is that they have a relatively complex structure and are correspondingly expensive and expensive to manufacture.
  • an inner tube that conducts fresh water should be suitable for drinking water, as special hygiene requirements must be met. Such requirements may result from legal requirements and are subject to change. Consequently, material selection for hoses that channel fresh water may be limited. Furthermore, this can result in that tube materials are used which have a reduced strength.
  • an object of the present invention is to provide an improved hose device, which in particular has a simplified structure.
  • a hose device for a water-conducting household appliance with a first connection for connection to a water supply network, a second connection for connection to the household appliance, exactly one hose, which is arranged between the first connection and the second connection, wherein the hose designed as a single-walled corrugated hose and is adapted to supply water to the household appliance, and a pressure reducer, which is adapted to reduce pressure surges from the water supply network in the corrugated hose.
  • the pressure reducer is arranged in the flow direction in front of the corrugated hose. The likelihood of leakage is therefore greatly reduced, so that no further outer tube is necessary to catch leakage fluid.
  • the water-conducting 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 may, for example, comprise a connecting portion, which projects into a first connecting portion of the corrugated tube and is connected thereto.
  • the first connection may comprise a filter for filtering water.

  • the connector of the second terminal comprises a connecting portion which projects, for example, into a second connecting portion of the corrugated hose and is connected thereto.
  • a “single-walled hose” means a hose which comprises a simple wall and, in particular, is designed in one piece, in one piece or in one piece of material.

  • Corrugated hoses have the advantage that bending them is facilitated and damage due to kinking rarely occur.
  • the corrugated tube provides fluid communication between the first port and the second port.
  • the pressure reducer is a device that particularly effectively dampens pressure surges from the pipe network, so that the corrugated hose is spared. Furthermore, the pressure reducer is set up, for example, to abruptly reduce a flow cross-section in the event of a pressure surge occurring in the water supply network, in order to reduce the pressure surge into the corrugated hose.
  • the pressure reducer is configured to reduce a pressure of a pressure surge in the corrugated hose to less than 50%, 40% or 30% of the pressure 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 produced with a correspondingly reduced wall thickness.
  • the hose device is formed between the first connection and the corrugated hose without safety valve for shutting off a flow of water into the corrugated hose in the event of leakage therefrom.
