Definitions

  • the present invention relates to dishwashers, and in particular to a dishwasher provided with a device for recovering the heat dissipated during the wash phase.
  • the direct contact implies that the water stored in the external container immediately absorbs heat as soon as the tank starts to heat up, whereby in practice the dishwasher resistor has to heat not only the water loaded in the tank for the present wash phase but also that for the following phase. This results in an extension of the time required to reach the temperature set for the wash, and in a greater dissipation of heat from the external container during the waiting phase before the water stored therein is used.
  • the object of the present invention is to provide a dishwasher which overcomes the above-mentioned drawbacks.
  • This object is achieved by means of a dishwasher provided with a container, for the water to be used in the following wash phase, arranged outside the wash tank and extending at least over one side of the tank yet not in contact therewith.
  • Other advantageous features of the present dishwasher are disclosed in the dependent claims.
  • the main advantage of this dishwasher stems from the fact that the water stored in the external container is not heated by contact with the tank but only by capturing the heat radiated therefrom, so that it does not affect the duration and consumption of the present wash phase yet recovering heat that would otherwise be wasted.
  • a further advantage of the present dishwasher is that the heat recovery is achieved by means of a simple and inexpensive device, which can be arranged in spaces around the tank that would otherwise remain unused.
  • a dishwasher according to the present invention is provided with a container C arranged outside the wash tank T between the latter and the external casing E of the machine.
  • the novel aspect of the present invention resides in the fact that the external container C is not in contact with tank T, so as not to absorb heat therefrom by contact.
  • container C extends over the side and bottom portions of the dishwasher so as to obtain a high-capacity container (even 8-10 litres indicatively, depending on the available room) inside which there is stored water intended for the following wash phase.
  • the water is loaded from the network through a first pipe P1 and after passing through the air-break A and the softener S it goes through a second pipe P2 to build up in container C, from where it passes then to tank T through a third pipe P3. From the following cycle, the water entering tank T will no longer come directly from the network but it will be the water stored in container C. Therefore, its temperature will not be 15°C but at least 23°C, assuming said temperature as room temperature, and this increase in temperature will be at no cost.
  • the water is heated in tank T and due to the heat radiated from the tank the temperature in the spaces of the dishwasher surrounding the tank increases. Said increase in temperature leads to a heating of the water stored in container C thanks to the captured heat, that would otherwise be wasted.
  • the water will have a temperature higher than the 23°C assumed as room temperature because it will have benefited from the heat coming from the tank.
  • container C may change according to the required capacity and to the room available between tank T and the external casing E.
  • container C could even extend over multiple sides of tank T until it substantially completely encloses it so as to maximize the heat recovery, possibly being divided into several separate containers that each feed tank T.
