Definitions

  • the present invention relates to washing machines, and in particular to a washing machine with a sink integrated therein.
  • the object of the present invention is to provide a washing machine with integrated sink which overcomes the above-mentioned drawbacks. This object is achieved by means of a washing machine with integrated sink having the characteristics disclosed in claim 1. Other advantageous features of the present washing machine with integrated sink are disclosed in the dependent claims.
  • a first important advantage of the washing machine with integrated sink according to the present invention is that the sink operates independently of the washing machine, whereby it is possible to use both of them simultaneously and there is no risk of contamination of the laundry even when particular additives are used in the sink.
  • a second significant advantage of this washing machine with integrated sink is that the two drain pipes, of the sink and of washing machine, converge into a single pipe that can be connected to any wall drain. In this way the proper operation of the sink is independent of the position of the wall drain, contrary to what occurs with a sink having a conventional drain trap that must be located in front of the drain in order to operate properly. As a consequence, the washing machine can be located in the position most convenient for the user, without having to arrange a wall drain at that position and being able to change position subsequently without any problem.
  • Still another advantage of said washing machine with integrated sink stems from its simple structure, that makes it inexpensive and reliable.
  • a washing machine with integrated sink conventionally includes a sink 1 integrated into the top of the washing machine casing, with a relevant tap 2 fed through pipes 3 for the hot and cold water.
  • the washing machine includes, among the other components, a wash tank 4 from which the water is drained by means of a first drain pump 5, controlled by a control unit 6, that directs the water through a first drain pipe 7 to a drain 8 that may be either a stand-alone drain or a wall drain.
  • the novel aspect of the present invention resides in the drain system of sink 1, that includes a second drain pipe 9 extending down to an expansion sump 10 from which the water is drained by means of a second drain pump 11 that directs the water to drain 8 through a third drain pipe 12 that converges into the first drain pipe 7 prior to exiting the washing machine.
  • the activation of the drain pump 11 is controlled by the control unit 6, which is operatively connected to a pressure switch 13 or other similar means for detecting the water level inside sump 10 (e.g. a float sensor).
  • the present washing machine with integrated sink is also preferably provided with various clever devices that, although not strictly indispensable, are used to optimize its operation.
  • the operation of the drain pump 11 of sink 1 is controlled not only by pressure switch 13 but also by a timer, integrated into the control unit 6, provided to prevent a continuous switching on/off of pump 11 as soon as the latter starts to empty sump 10.
  • the two hydraulic circuits of the washing machine and of the sink are separated and made independent by a pair of non-return valves 14, 14', preferably mechanically operated, arranged in the respective converging drain pipes 7 and 12. Furthermore, a vent valve 15 is provided on sump 10 in order to prevent cavitation problems of pump 11, which is in communication with the outside through sump 10 and pipe 9.
  • a drain trap is formed inside sump 10 in order to prevent problems caused by the stagnation of water in the expansion sump 10, and resulting bad smell that might rise along the drain pipe 9.
  • a flood-prevention system consisting of normally closed electrovalves 16 arranged on the feed pipes 3 of tap 2, so as to stop the flow of water to tap 2 in case electric power is lacking and therefore the drain pump 11 of sink 1 can not drain the water.
