Definitions

  • This invention relates to a household-type dishwashing machine, particularly such one with a large load capacity.
  • Household-type dishwashing machines have standard overall and installation dimensions and they are generally made as substantially disclosed in IT-A-1 159 635, with a wash tank accomodating an upper basket and a lower basket provided to support the washload items which are then washed by means of spray nozzles that are associated to the baskets.
  • the wash tank has a front opening that is normally closed by a hollow door assembly comprising a door liner protruding inwards into the wash tank. More precisely, an upper portion of the hollow door assembly is assigned a greater depth so that it is capable to accomodate control and setting elements of the machine, as well as any other operational member or element of the machine which the user should be able to reach as conveniently as possible, such as for instance detergent and rinse aid dispensers.
  • Such a thicker portion of the door assembly which is protruding inwards, causes the greatest allowable depth of the upper basket to be reduced correspondingly, so that said upper basket has usually a smaller depth than its lower counterpart and this in turn causes the overall load capacity of the dishwashing machine to be undesirably reduced.
  • the above cited IT-A-1 159 635 discloses a concept according to which the lower basket is made up by various complementary portions that are adapted to be coupled to each other, ie. a first portion having the same dimensions as the upper basket, and at least a second portion which can be hooked up frontally to said first portion and can possibly be used for supporting cutlery pieces.
  • Dishwashing nachines have been proposed recently which have a standard height of 91 cm instead of the usual 86-cm height. It is therefore possible in this case to increase the height of the wash tank in which, above the upper basket, a further basket with a reduced height can be accomodated for holding cutlery and similar items. Such an embodiment is described for instance in DE-A-4 028 908.
  • a dishwashing machine is also known from DE-A-4 022 269 to comprise a third cutlery-holding basket which is attached directly to the door liner, in correspondence with the lower, shallower portion of the door assembly.
  • said third basket is made complicated by the need to provide it with a removable lid in order to prevent cutlery items from falling down when the door is being closed.
  • the dishwashing machine is shown to comprise an outer casing 1 with a worktop plate 2, and has standard overall dimensions with a height which is preferably, but not exclusively, of approx. 90 cm.
  • the outer cabinet 1 houses a wash tank 3 which is substantially parallelepiped in its shape and has an open front side that can be closed tightly by means of a door assembly 4 which is hinged on a horizontal axis 5 and is preferably hollow in its structure.
  • the outer surface of said door assembly 4 is substantially flush with the front edge of the machine.
  • substantially the whole of the inner surface, or door liner 6, of the door assembly 4 is receding outwards, as this is apparent in Figure 1.
  • an upper basket 7 and a lower basket 8 which, in a per sè known manner, are both substantially horizontal, capable of being slidably drawn out, adapted to support the tableware items to be washed, and associated to respective rotary spray arms (not shown for greater simplicity).
  • the baskets 7, 8 are housed in the wash tank where they extend to a substantially similar depth corresponding substantially to the full inner depth of the wash tank 3 as defined between said inner surface 6 of the door assembly and the rear wall 9 of the tank.
  • the door assembly 4 has a relatively reduced thickness, so that it is not possible to accomodate user-accessible operational elements, such as for instance control means for the operation of the machine and washing and rinse aid dispensing means, inside it.
  • user-accessible operational elements such as for instance control means for the operation of the machine and washing and rinse aid dispensing means, inside it.
  • at least part of such user-accessible operational means of the machine are arranged in the outer casing 1 of the machine, on the outside of the door assembly 4, preferably above the wash tank 3, in a reduced-height space extending between said wash tank 3 and the worktop 2.
  • said control means for the operation of the machine may include a prgramme sequence control device 10 of the electromechanical type comprising a shaft 12 that is actuatable by means of a knob 11.
  • a prgramme sequence control device 10 of the electromechanical type comprising a shaft 12 that is actuatable by means of a knob 11.
  • said shaft 12 and knob 11 are preferably arranged with their axis substantially vertical.
  • the side surface of the knob 11 is accessible from the outside through a front opening 13 provided in the outer casing of the machine, much in the same way as described in GB-A-2 269 002.
  • said programme sequence control device may be of an electronic type, actuatable through push-buttons or keypads and having particularly reduced space requirements.
  • said programme sequence control device can be mounted in any suitable location and position inside the outer casing 1 of the machine, ie. even in the door assembly 4 as this is described for instance in GB-A-2 238 576.
  • washing and rinse aid dispensing means are located outside the door assembly 4, as previously mentioned.
  • wash and rinse aid dispensing means include a detergent dispenser 14 and a rinse aid dispenser 15, and both of them are accessible from the front side of the machine.
  • said dispensers 14 and 15 may be of the sliding drawer type, with one or more compartments, as they are typically used in automatic clothes washing machines, and they communicate with the inside of the wash tank 3 through respective openings 16, 17.
  • at least the detergent dispenser 14 is adapted to be operated by the programme sequence control device 10 through operational connections that are generally indicated with 16 in Figure 2.
  • both the programme sequence control device 10 and the detergent and rinse aid dispensers 14 and 15 are installed on the outside of the door assembly 4, the latter may advantageously be free from any wire harness or cable, which should notoriously be adequately flexible and would give rise to manufacturing complications, as well as reliability and electrical insulation problems.
  • the door assembly 4 can therefore be made in a particularly simple way and lends itself to the provision of a most complete and effective noise deadening insulation.
  • the above described dishwashing machine may be the subject of anyone of a number of modifications that may be considered to be suitable without departing from the scope of the present invention.
  • at least one of the baskets 7, 8 may be constituted by a plurality of complementary portions that are adapted to be coupled to each other, as this is described in the afore cited specification IT-A-1 159 635.
