Definitions

  • the present invention relates to dishwashers, and in particular to a dishwasher provided with a noise reduction member.
  • modem dishwashers have reached high levels of silence, but said silence is obtained thanks to the use of large amounts of bituminous materials applied to the external walls of the wash tank.
  • the use of such materials has the drawback of leading to an increase in power consumption during the operation of the machine, since these materials heat up by absorbing heat stolen from the water. Due to this, conventional dishwashers have difficulties in achieving high levels of power efficiency.
  • 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 noise reduction member arranged between the tank bottom and the lower sprinkler. Other advantageous features of the present dishwasher are disclosed in the dependent claims.
  • the main advantage of the dishwasher according to the present invention is that of obtaining a noise reduction without increasing the power consumption, or at most with an extremely reduced increase, so as to achieve a high power efficiency.
  • a further advantage of this dishwasher stems from the structural simplicity of the devised arrangement, which implies significant savings both in material and labour during the manufacturing step.
  • a dishwasher in a dishwasher according to the present invention the water falling on the bottom 1 of the wash tank is intercepted by a member 2, preferably having an inverted frustoconical shape, secured at the ends of the lower sprinkler 3 so as to be supported between the latter and bottom 1.
  • the sloped walls of the noise reduction member 2 preferably converge to a central hole 4 to drain the intercepted water to bottom 1, said hole 4 being preferably formed close to the region where the dishwasher filter (not shown) is located.
  • member 2 it would be possible to shape member 2 so that it extends beyond the lower sprinkler 3, with a suitable play with respect to the tank walls, thus minimizing the area of bottom 1 not covered by member 2.
  • the latter can be made of a plastic material or the like, with a small thickness and weight so as to prevent useless increases in the power absorbed by member 2.
  • the second embodiment illustrated in fig.2 shows how a similar member 2' can also be directly supported by the tank bottom 1 as long as this is achieved through insulating supports, such as rubber feet 5, suitable to prevent the transmission of the vibrations from member 2' to bottom 1.
  • This arrangement makes easier to establish the size of member 2' so that it intercepts substantially all the water falling on bottom 1, since such a member 2' does not rotate with sprinkler 3 and therefore can be placed on bottom 1 with a minimum play.
  • the noise reduction member can be made with different shapes and materials, for example with a wavy surface and/or a fine mesh structure that intercepts the drops yet allows the water to pass through to bottom 1 even in the absence of the central hole 4.
