    Description


    [0001] The invention relates to domestic appliances, such as washing machines, tumble-driers, dishwashers and the like, with a water outlet system with outlet hose.

    [0002] In installing domestic appliances the outlet hose should be easily accessible after the removal of the packaging and be capable of being easily extended to the correct length for attachment to the local outlet system. In addition, the outlet hose already led out of the casing of the appliance, requires a larger pack for outlet hose arranged on the rear panel of the machine housing for the packaging, storage and transport.

    [0003] US-A-4 715 402 discloses an appliance having a hose retainer for removably receiving the outlet hose within a cabinet of the appliance. The appliance includes accen parts for affording access to a portion of the hose for pulling it outwardly.

    [0004] It is an object of the invention to arrange the outlet hose for a domestic appliance of the above-mentioned type for packaging, storage and transport, so that the size of the packaging is determined only by the dimensions of the appliance housing and that the outlet hose can be rapidly and simply connected with the local outlet system at the point of use.

    [0005] This object is met by the invention in, by providing in the rear panel of the appliance housing, an outwardly open receiving assembly for the end of the outlet hose and the outlet hose installed so that it can be drawn out, is introduced into the receiving assembly through an inlet and is set up for packaging, storage and transport of the domestic appliance with its end in an outlet.

    [0006] The end of the outlet hose is inserted in the receiving assembly and arranged in such a way that it is lightly held and can be withdrawn from the appliance housing. In this way the size of the packaging required can be reduced to the dimensions of the appliance casing, without hindering connection of the outlet hose to the local outlet system. All that is required is simply to withdraw the outlet hose from the appliance casing until there is a sufficient length free for connection. Handling is simplified as a result of the fact that the end of the outlet hose is held in an arcuate holder, which extends with the end of the outlet hose in the receiving assembly from entry to exit and does not extend with the outlet hose beyond the receiving assembly. The end of the outlet hose can then be easily held.

    [0007] For safety reasons it is envisaged that the part of the outlet hose introduced into the appliance casing should be provided with a stop which, after removal of the end of the outlet hose from the receiving assembly, limits the extraction movement of the outlet hose through impact of the stop against the inlet, so that the connection of the outlet hose to the internal outlet of the appliance within the appliance casing is not subjected to an unnecessary tensile force.

    [0008] If the outlet hose is not firmly attached to a local outlet system then it is advantageous to provide an embodiment which is characterised by the provision of a suspension lug on the holder. The outlet hose can then be suspended after use.

    [0009] In accordance with a further embodiment retaining elements are provided, preferably moulded-on formed, on the receiving assembly to fix the outlet hose in the operating position and for fixing the mains plug of the appliance connecting cable. The mains plug of the appliance connecting cable will then also be accepted by the receiving assembly and held securely at least in the packed condition of the domestic appliance. It is thus envisaged that the retaining device for the appliance connecting cable is covered with the holder so that the domestic appliance can only be electrically connected when the outlet hose has been removed from its not-in-service position in the receiving assembly.

    [0010] The entry and the exit for the outlet hose is preferably moulded-on formed in the receiving assembly.

    [0011] The incorporation of the receiving assembly into the rear panel is preferably done in such a way that the receiving assembly is provided with entry and exit openings positioned vertically above one another in a marginal area of the rear panel. Adequate space is then available between the appliance unit and the adjacent side wall of the appliance casing for the extractable storage of the outlet hose.

    [0012] For the incorporation of the receiving assembly in the rear panel it is envisaged, in one embodiment, that the receiving assembly be provided with a circumferential attachment flange in which the fastening seating for connecting the receiving assembly inserted in a recess in the rear panel with the rear panel is built in.

    [0013] To enable the exit aperture for the outlet hose in the receiving assembly which is no longer required in the operating condition to be closed, one embodiment envisages that a closure lid for the exit is provided by means of an elastic connecting member, in particular moulded-on.

    [0014] If the appliance outlet system has an extraction pump, the outlet hose is connected to the outlet of this extraction pump.

    [0015] The invention will be illustrated in more detail by way of an example of an embodiment with the aid of the drawings.

    shows a perspective view of the rear panel of the appliance casing of an electrical domestic appliance using water with outlet hose and appliance connecting cable.

    [0016] The domestic appliance with the machine assembly is enclosed in an appliance casing 10 where the machine assembly is adapted according to the function of the domestic appliance as a washing machine, tumble-drier, dishwasher and the like. The design of the machine assembly is not of significance for the purposes of the present invention and is not therefore explained in more detail.

    [0017] 11 indicates the rear panel of the appliance casing 10. An outwardly opening, trough-like receiving assembly 20 is set into this rear panel 11. If the internal outlet system within the appliance is provided with an extraction pump 13, then an outlet hose with the end 17 (Fig. 2) turned towards it is connected to the outlay from this extraction pump 13. The receiving assembly 20 is arranged in a vertical boundary region of this rear panel 11 and has an entry 21 and an exit 22 for the end of the outlet hose 14. The entry 21 serves to introduce the outlet hose 14 into the receiving assembly 20 and the end of the outlet hose 14 can be inserted into the exit 22 and held in the receiving assembly 20. Entry 21 and exit 22 can be integrally formed in one piece as sleeves on the receiving assembly 20.

    [0018] The end of the outlet hose 14 can be held in an arcuate holder 16 which extends from the entry 21 to the exit 22 and which holds the outlet hose 14 on removal from the receiving assembly 20. The holder 16 may be clamped only to the end of the outlet hose 14, so that it can be removed when the outlet hose 14 is attached to the local outlet system. If the connection of the outlet hose to the local outlet system is not fixed, then it can be hung on the holder 16 provided with a suspension lug 17.

    [0019] The receiving assembly 20 may comprise a retaining member 28 covered by the holder 16 which can be employed to receive the mains plug of the appliance connecting cable 30, as shown in Figs. 1 and 2. Before the plug of the appliance power cable can be accessed the end of the outlet cable 14 held in the receiving assembly 20 must be removed and the holder 16 taken out of the receiving assembly 20. This will release the exit 22 and can be covered with a closure cap 26, as shown in Fig. 3.

    [0020] This closure cap 26 is moulded-on through an elastic connecting member 27 on the receiving assembly 20.

    [0021] The outlet hose 14 is withdrawn from the appliance casing 10 until the length required for connection to the local outlet system is attained, where the outlet hose is led into the entry 21. A stop 15 provided on the outlet hose 14 limits the maximum extractable length. As made clear in Fig. 1, the outlet hose 14 can be stowed extractably in a sufficient length between the machine assembly and the adjacent side wall 12 of the appliance casing 10.

    [0022] As shown in Fig. 2, the receiving assembly 20 is provided with a circumferential attachment flange 31 in which the apertures 23 and 24 required for attachment to the rear panel 11 are provided. The receiving assembly 20 is inserted in a cut-out in the rear panel 11. In addition, the receiving assembly 20 may comprise additional retaining elements 25 which may be employed to hold the outlet hose 14 in its operating position. The holder 16 may also be held in additional retaining elements in the receiving assembly 20.
