Definitions

  • the present invention relates to a device for electrical domestic apparatus, in particular for a dishwashing machine.
  • this device comprises:
  • the breather chamber serves to allow vapours which occur during the washing operation to escape from the vessel.
  • the wall around the neck of the receptacle, for its part, ensures that any salt and/or brine which may escape from the interior of the neck or overflow from it remains confined within the air space, without coming into contact with metal parts of the electrical domestic apparatus.
  • the breather chamber is put into communication with the washing vessel by an opening formed suitably in a side wall of the washing vessel and communicating with the chamber via a suitable bush.
  • the object of the present invention is a device of the type initially indicated in the present description and characterised in that the said breather chamber communicates with the washing vessel through the said air space.
  • the device of the apparatus thus makes use of a pre-existing element of one of its constituent parts - that is the annular air space around the neck of the receptacle - to guarantee communication between the breather chamber and the washing vessel.
  • the device of the invention is less bulky than those of the prior art and guarantees a better hydraulic seal of the vessel.
  • a device for electrical domestic apparatus in particular for a dishwasher machine, is produced in the form of an integrated component (Figure 1) which comprises a receptacle 10 and a breather chamber 12 forming part of the mains-water fill circuit.
  • the receptacle 10 contains salt intended, once mixed with water, to form a brine for regeneration of a decalcifier, known per se and not illustrated in the drawings.
  • the receptacle 10 includes a casing 14 within which there is defined a chamber 16 for containing the brine and from which projects a neck 18 by which the chamber 16 communicates with the washing vessel 20 of the apparatus.
  • the neck 18 is surrounded by an outer wall 22 in such a way as to define an annular air space 24 between the wall 22 and the neck 18, which is disposed coaxially thereof.
  • the air space 24 is connected by a duct 26 to the washing tank (not illustrated in the drawings) of the vessel 20.
  • an adjustment rod 29 projects into the air space 24, which, in a manner known per se and not illustrated in the drawings, allows the adjustment of the flow of water through the receptacle 10 for the formation of a decalcifier regeneration brine having a desired saline content.
  • the structure and manner of operation of an adjustment device of this type are for example described in DE-A-196 03 619.
  • a removable closure plug 28 which has a head 30 and a stem 32 capable of engaging the wall 22 is also associated with the receptacle 10.
  • the stem 32 is threaded and engageable on a thread formed on the outer surface of the wall 22.
  • the stem 32 there is also formed a plurality of circumferentially spaced slots 34 capable of putting the washing vessel 20 into communication with the air space 24 even when the plug 28 is screwed onto the wall 22.
  • the head 30 of the plug 28 is provided internally with a seal 36 capable of sealing against the upper edge of the neck 18.
  • the plug 28 is further provided with a skirt 38 disposed coaxially outside the stem 32.
  • the breather chamber 12 communicates, through an aperture 40, with the external environment and, through a section 42 of the duct 26, with the air space 24 which is in turn in communication with the washing vessel 20 through the slots 34.
  • the section 42 of the duct 26 as well as the neck 18 and the air space 24 are located at the lower part of the washing vessel 20.
  • the breather chamber 12 communicates through a section 43 of the duct 26 - disposed in series with the section 42 and forming part of the water fill supply circuit of the dishwashing machine - with the washing tank.
  • the presence of the wall 22 around the neck 18 ensures that - when salt is being introduced into the receptacle 10, from which the plug 28 has been previously unscrewed - the salt and/or any possible brine splashing out of the neck 18 or overflowing out from it, remains confined within the air space 24 and, through the duct 26, is directed to the wash tank without coming into contact with any metal parts which could become corroded.
  • the vessel 20 is in communication with the breather chamber 12 through the slots 34, the air space 24 and the section 42 of the duct 26. Therefore, thanks to this communication, vapours which are generated in the vessel 20 can be directed continuously into the breather chamber 12 and from here discharged to the outside via the aperture 40, or directly condensed. In this latter case the water of condensation formed in the chamber 12 is discharged into the wash tank through the section 43 of the duct 26.
  • the skirt 38 of the plug 28 which protects the slots 34, serves to prevent entry into the air space 24 of any water spray from the vessel 20 in addition to the vapour to be discharged through the chamber 12.
  • Figure 2 illustrates an alternative embodiment of the invention in which the same reference numerals have been utilised as in Figure 1 to distinguish the same or equivalent parts.
  • the threaded stem 44 of the plug 28 can engage a corresponding thread formed on the outer surface of the neck 18 rather than on the wall 22.
