Definitions

  • the present invention relates to a washing machine for dishes and other ware and to the washing process using said machine.
  • dishwashers which comprise a washing area, equipped with fixed or moveable nozzles for the supply of a liquid substance, generally water mixed with detergents/cleansing agents, and a pump connected to the above nozzles for the pressurized feeding of the same liquid substance.
  • a first category relates to washing machines which assemble a medium/low-power pump, for example about 500-3000 Watt, which are used exclusively for the washing of dishes.
  • the second category relates to washing machines which assemble a medium/high-power pumping group, for example about 3000-6000 Watt, which are used for the washing of saucepans, containers, cooking utensils, etc. which normally have a much greater degree of dirt than dishes.
  • washing machines are commonly called “warewashers” indicating the fact that they are capable of cleaning the above elements which will be called herein with the term “other items”, which differ in the greater degree of dirt with respect to that present on dishes.
  • the machines comprise a single operating station suitable for both washing and rinsing
  • the second category comprises so-called “tunnel machines” in which the washing and rinsing stations are distinct and separate areas.
  • the latter tunnel machines generally consist of three main functioning areas situated in series, pre-washing, washing and rinsing respectively, through which, during the functioning of the machine, the dishes or "other ware” pass, depending on the power of the pump installed, situated on specific moving means, such as conveyor belts or baskets.
  • washing machines As already specified above, whether they be single-station washing machines or tunnel washing machines, at present there are no washing machines suitable for washing both dishes and other ware without having to resort to incorrect washings or with high energy consumption.
  • An objective of the present invention is to provide a device capable of solving the above drawbacks of the known art in an extremely simple, economical and particular functional way.
  • Another objective of the invention is to provide a machine and washing process for dishes and other ware capable of correctly cleaning both the dishes and other ware using the necessary power each time without energy waste.
  • this shows a single-station washing machine 10 for dishes and other ware according to the present invention
  • figure 2 shows a tunnel washing machine 100 for dishes and other ware according to the present invention.
  • the washing machine 10, 100 for dishes and/or other ware comprises at least one washing area 11 equipped with supply means 12, 13 of a liquid substance, generally water or water mixed with detergents, suitable for being distributed under pressure on the dishes and/or other ware to be washed.
  • a liquid substance generally water or water mixed with detergents
  • the washing machine 10 is a single-station washing machine 10
  • the washing machine 100 is a tunnel washing machine.
  • the washing machine 10, 100 for dishes and/or other ware for distributing the above liquid substance, according to a pressure established each time, on the dishes and/or other ware to be washed also comprises at least two centrifugal feeding pumps 14, 15 connected to the supply means 12, 13, said pumps being situated in series one after another and can be independently activated.
  • the powers of the above at least two centrifugal pumps 14, 15 can be the same or different and, as already mentioned, can be independently activated for producing various configurations of use, or different supply pressures of the liquid substance, according to the requirements.
  • the washing machine 10, 100 in accordance with the present invention allows both dishes and other dirtier ware to be washed, always obtaining an optimum cleaning degree without wasting energy by feeding the supply means 12, 13 each time with an optimal pressure for the desired washing.
  • Any possible energy waste is in fact minimized by activating, according to the requirements, one or more pumps of the at least two pumps 14, 15 present, in relation to the ware to be washed.
  • the activation, depending on the requirements, of the above at least two pumps 14, 15 is therefore of particular importance and, according to the present invention, said activation can be manual or, alternatively, automatic.
  • the washing machine 10, 100 also comprises automatic activation means 16, 17 of the at least two centrifugal pumps 14, 15.
  • Said automatic activation means 16, 17 of the at least two centrifugal pumps 14, 15 can, for example, be at least one optical sensor 16 electronically connected to the at least two centrifugal pumps 14, 15, or alternatively they can be at least one captive sensor 17, also electronically connected to the at least two centrifugal pumps 14, 15.
  • said at least one optical sensor 16 or said at least one captive sensor 17 are preferably positioned at the entrance of the washing area 11 to analyze the degree of dirt of the ware entering the washing area 11 itself.
  • the machine 100 is a tunnel washing machine 100 and, in addition to the washing area 11, comprises a pre-washing area 20 and at least one rinsing area 21.
  • the dishes and/or other ware to be washed possibly positioned on specific transporting means, such as conveyor belts or baskets, pass through these areas, according to the succession shown in figure 2 .
  • the stations of the pre-washing area 20 and washing area 11 have a pre-washing tank 22, a washing tank 23 respectively, to which they are connected by at least one pump 24, and by the above at least two pumps 14, 15, respectively.
  • the supply means 12, 13 connected to the at least two pumps 14, 15 are spray nozzles 13 situated on specific collector arms 12.
  • the rinsing station 21 is equipped with a rinsing tank 30 connected by a pump 31 to an upper transversal collector arm 25 and a lower transversal collector arm 26, each equipped with a plurality of spray nozzles 27.
  • the rinsing station 21 advantageously also has at least one additional supply arm 28, 29 which can be activated or deactivated in relation to the advance rate of the dishes.
  • Said supply arm 28, 29 is activated when the machine functions with a high feeding rate of the dishes and is deactivated at a low speed.
  • the rinsing station 21 also comprises at least one regulation valve 32 suitable for activating or deactivating the supply arm 28, 29 in relation to the advance rate of the dishes.
  • a boiler 33 for heating the water to be supplied during the rinsing, at least one electrovalve 34 for closing or opening the connection with the water supply which feeds the rinsing water.
  • both the pre-washing and the rinsing are effected in the same washing area 11 with the difference that the pressurized liquid substance supplied is different each time and suitable for the treatment required and taken from a relative tank 40.
  • the washing process for dishes and other ware by means of a washing machine 10, 100 as described above and object of the present invention comprises the following phases:
  • washing machine 10, 100 object of the present invention, it is possible to wash both normal dishes and also other ware by selectively activating at least one of the at least two centrifugal pumps 14, 15 depending on the degree of dirt present on the dishes and/or other ware.
  • the energy power consumed for pressurizing the washing/rinsing liquid is therefore correctly dimensioned each time to the required washing level.
  • the phase of introducing the dishes and/or other ware into the washing area 11 can be effected manually, as in the presence of the single-station washing machine 10 shown in figure 1 , or automatically, as in the presence of the tunnel washing machine 100 shown in figure 2 .
  • phase of analyzing the degree of dirt present on the dishes and/or other ware can also advantageously be effected automatically, for example by means of at least one optical sensor 16 electronically connected to the at least two centrifugal pumps 14, 15, or by means of at least one captive sensor 17 also electronically connected to the at least two centrifugal pumps 14, 15.
  • the activation phase of at least one of the two centrifugal pumps 14, 15 for obtaining said required pressure without energy waste can be effected manually or automatically through the above automatic activation means 16, 17.
