Definitions

  • the invention concerns a hose set, with a hose and at least one first connector suitable to be coupled to a washing machine or a dishwasher with an electric manipulator valve, wherein the first connector comprises a partially pipe liked shape single-piece element with an attachment portion, with the pipe like shaped single-piece element partially surrounded by the hose.
  • a hose set according to claim 1 in which the attachment portion is configured to be directly brought in contact with the valve to allow a fluid communication therebetween.
  • hose set and a kit of parts it is possible to pre-assemble some components, such as plastic pipes in the valve body or flow regulator supports in the plastic pipes.
  • the assembly operation is simplified as no further necessity exists to assembly a fixing nut to the hose set or to assemble a gasket in the hose set on its valve side. Further it is avoided to assembly a flow regulator support in the inlet of the valve. No necessity exists to screw the fixing nut on a thread in an inlet of the valve.
  • the first filter is configured as a hollow cone, wherein the tip of the cone is directed towards the attachment portion and/or the filter is in direct contact with the co-operatingly shaped inside of the first connector, the assembly can be even easier conducted.
  • the hose comprises on an opposed end to the first connector, a second connector, which is inserted in the hose and in contact with a fixing nut to be coupled to a water supply.
  • the fixing nut is configured as a separate element to the second connector, encompassing a radial shoulder with the second connector, differently configured spigots can be connected to the hose.
  • a gasket is positioned in sealing engagement with the fixing nut and the second connector.
  • the gasket is positioning a second filter, which is extending within the second connector, the water quality is further enhanced and the assembly is simplified.
  • a flow regulator washer is positioned in a cavity between a second filter and a second connector.
  • the assembly process is simplified such that first the second connector is inserted in the fixing nut followed by the flow regulator washer being inserted in the second connector and being precisely positioned by the shaft, wherein the second filter is finally positioned by use of the gasket, whereby the gasket is pushed on the second connector and squeezed on the inside of the fixing nut when the fixing nut is screwed to a spigot.
  • the shaft can be alternatively configured without any hole.
  • the stepped hole such as a stepped through-hole itself renders the waterflow through the hose into the valve more stable.
  • the second filter can be positioned very easily, if the second filter has a mainly cylindrical outer surface with cylindrical grooves. Again, it is stressed, that the shaft can be reconfigured without such a hole.
  • the positioning for the first filter in the first connector and the fixing of the hose to the first connector can be provided in one manufacturing step if at least one of the ends of the hose of rubber or plastic material is pressed on the outer surface of the first connector of plastic material by a clamp to avoid loosening.
  • connection is long lasting and cost-effective producible, if the clamp is of metallic material.
  • the manufacturer of the washing machine or the dishwasher with their respective valves integrates the first connector to the electric valve.
  • the hose set or a kit of parts can be yet easier assembled even if the assembler is unskilled in the assembly process.
  • Such a washing machine or dishwasher then can be quickly connected without problems by an end user to the spigot or water tap.
  • a hose set with a first connector is disclosed, wherein the first connector has been connected to a valve of a dishwasher or a washing machine.
  • Figure 1 discloses a hose set 1 according to the invention.
  • the hose set 1 comprises a hose 2 of rubber or plastic material. This hose 2 surrounds at a first end 3 a first connector 4.
  • the first connector 4 comprises a partially pipelike shaped single-piece element with an attachment portion 6.
  • a serrated structure 7 with grooves is configured on the outside of the single piece element 5 in the section being pipelike formed.
  • the serrated structure 7 can also be denominated as a serrated surface.
  • the hose 2 is surrounded at its first end 3 by a metallic clamp 8.
  • the clamp 8 executes radially pressure on the compressible material of the hose 2, so that a form- and/or force-fit between the hose 2 and the single-piece element 5 is achieved.
  • the first connector 4 is fixed to an electrically manipulatable valve 9.
  • the valve 9 can alternatively be mechanically or electromechanically manipulatable.
  • the valve 9 is configured in the current embodiment as a so called “double” valve but can also be configured as a "single” valve or a “triple” valve.
  • the attachment portion 6 is e.g. welded to the valve 9. Other connection types such as gluing or press-fitting are also possible.
  • attachment portion 6 and the valve are made of one piece, so that there is no need for assembly at all.
  • a first filter 10 is positioned in the pipelike formed section of the single-piece element 5.
  • the first filter 10 is having a constant valve thickness.
  • the first filter 10 has an outer conical configuration with an hollow inner chamber. The chamber is closed in direction to the valve 9. Further, the first filter 10 is positioned such that the smaller diameter is directed to the valve 9 and the radial diameter is directed to a water tap, which is positioned on the other side of the hose 2.
  • the first filter 10 can also be absent and if present, can be positioned in both directions.
  • the first filter 10 is positioned in the first connector 4 due to a distortion of the first connector 4 and the hose 2 by the clamp 8.
  • the metal clamp 8 is made of aluminum, copper or steel.
  • another similar metallic clamp 12 fixes the hose 2 to the second connector 13.
  • the second connector 13 also comprises a pipelike section 14 with a serrated outer surface.
  • the second connector 13 In contrast to the first connector 4 the second connector 13 is in contact with a fixing nut 15.
  • the fixing nut 15 engages a shoulder 16 of the second connector 13.
  • the gasket 17 is positioned in a groove 19 of the second filter 18.
  • This flow regulator washer 20 is surrounding a shaft 21 of the second connector 13.
  • the shaft 21 is having a stepped through hole 22.
  • the assembly process is simplified essentially in that the first connector 4 can be either previously fixed to the electric valve 9 or part of the valve body of the electric valve 9 and that the hose 2 can be fixed to the second connector 13 via the metallic clamp 12. Further the second connector 13 could be completed with the flow regulator 20 and the second filter 18 held in position by the gasket 17, whereby this combination is surrounded by a fixing nut 15.
  • the second end of the hose 2 has only to be pushed over the serrated structure 7 of the first connector 4 after the first filter 10 has been pushed into the last single piece element 5, whereas the metallic clamp 8 fixes all three elements in their respective position relative to each other. Finally only the fixing nut 15 has to be screwed on the spigot or the water tap.
