Definitions

  • the present invention relates to industrial dishwashers, and in particular to a hood-type dishwasher with an improved drying circuit aimed at a more effective and faster drying of the dishes.
  • the whole circuit is made up of plastic, rubber or steel members securely fixed to each other.
  • Such a type of circuit structure is easily achievable in a household dishwasher with front opening door, but in a hood-type industrial dishwasher there is generally preferred an air discharge drying system since a hood-type dishwasher is substantially divided into a stationary lower half and a mobile upper half.
  • the object of the present invention is to provide a hood-type industrial dishwasher which overcomes the above-mentioned drawbacks. This object is achieved by means of a hood-type industrial dishwasher provided with air recirculation drying circuit comprising a portion of the circuit arranged at the top of the hood. Other advantageous features of the present industrial dishwasher are disclosed in the dependent claims.
  • the main advantage of the dishwasher according to the present invention is that of being able to perform an effective drying of the dishes even in a short time thanks to the fact that the hottest and most humid portion of the air present within the wash chamber is efficiently sucked away at the top of the hood.
  • Such an arrangement of the suction mouth is also advantageous in that it is opposite with respect to the air reintroduction mouth located at the bottom of the wash chamber, so as to avoid “preferential paths” and to achieve an almost uniform airflow across the whole wash chamber for an optimal drying of all the dishes.
  • a further advantage of this dishwasher is, in its preferred embodiment, the arrangement of the drying device which is mostly located in the space available at the back of the machine, with a minimum additional bulk.
  • Still another advantage of the above-mentioned dishwasher, with respect to dishwashers with air discharge drying, is that of achieving the drying through air recirculation and therefore without a sudden decrease in the temperature of the dishes, thus allowing to exploit also the drying phase for the sanification.
  • a hood-type industrial dishwasher conventionally includes a parallelepipedal wash chamber defined on four sides (left, right, top, front) by hood 1, on the bottom side by tank 2 where the filters are located and water is collected, and on the back side by the vertical wall 3 of the stationary lower part, along which hood 1 slides.
  • the novel aspect of the industrial dishwasher according to the present invention is the presence of a suction duct 4 at the top of hood 1.
  • the inlet A of said duct 4 is preferably located along the front edge of hood 1, whereas outlet B is arranged at the back side, outside the wash chamber, oriented vertically downwards and tapered.
  • a vertical condensation duct 5 On the stationary rear wall 3 of the machine there is applied a vertical condensation duct 5, with a flared top inlet C suitable to receive the tapered outlet B of duct 4. Inside duct 5 there are arranged a fan 6, preferably a tangential fan in order to reduce its bulkiness, and a condenser 7. Duct 5 is connected to the wash chamber through an outlet D for the reintroduction of the dehumidified air, said outlet D being formed in the lower rear portion of the wash chamber.
  • a seal 8 is preferably provided between the suction duct 4 and the condensation duct 5, said seal being preferably arranged on the outside of outlet B but it could also be arranged on the inside of inlet C. It should also be noted that the tapering of outlet B, in addition to making easier the coupling between ducts 4 and 5, is also useful to prevent condensate drops from falling outside the condensation duct 5 when hood 1 is open as in Fig.1 .
  • fan 6 and/or condenser 7 could be replaced by other technically equivalent elements.
