Definitions

  • the present invention refers to a washing machine provided with a recirculation circuit.
  • washing machines and in particular washing machines and washer-dryers, include a support frame, on which a washing tub is mounted, inside which rotates a drum, wherein the garments to be washed are placed.
  • the tub has an opening through which the access to the drum is possible and clothes can be placed inside the drum.
  • Such machines also comprise a controlled hydraulic system, which provides the water supply, suitably mixed with detergent substances, so that the garments are subjected to the washing process.
  • a recirculation circuit which has the aim to facilitate the dissolution of the detergent in the water and to promote the circulation of water and detergent into the tub.
  • Document EP 2267211 A1 discloses a washing machine having a recirculation conduit connected to a spray nozzle that is arranged in the upper section of tub.
  • Document DE 3437886 A1 discloses a washing machine having a pump for the recirculation of the suds to deliver the recirculated suds to the detergents drawer.
  • FIG. 1 An exemplary recirculation circuit is disclosed in US 2005/0132758 A1 .
  • the conduit 110 output from the washing tub, which conveys the water and the detergent to the pump 130.
  • the latter provides to convey the water and the detergent towards the valve 150.
  • the washing fluid can be selectively inserted in the conduit 120, to then be distributed in a "rain mode" on the drum, or it can be diverted into the conduit 140, which brings it back to the pump 130 so as to define a closed circuit substantially outside the tub.
  • the valve 140 is controlled on the basis of the fact that the detergent needs to be further dissolved in water (deviation inside the conduit 140), or on the basis of the fact that the washing fluid should be distributed on the garments to be washed (forwarding to the conduit 120).
  • washing machine described in this document is characterized by a considerable constructional complexity and consequent particularly significant difficulty of assembly.
  • the object of the present invention is to provide a washing machine having a simplified structure, which can be easily and quickly assembled.

  • the Applicant believes that, in this way, a washing machine can be implemented wherein the recirculation circuit has a particularly simplified structure, easy to assemble and with a lower cost.
  • the second conduit allows a reintroduction of the fluid into the tub through a lower surface of the tub itself.
  • the end portion of the outlet conduit has a substantially cylindrical shape; the first conduit leads to a first radial opening of such an end portion.

  • first and/or second conduit have a corrugated shape, at least at a substantially middle portion thereof.
  • the recirculation circuit further includes a removable insert mounted at the second end of the second conduit, wherein said insert is such as to divert the flow of the fluid coming out from the second conduit by substantially 90° and make the same flow substantially parallel to the bottom the tub.

  • 1 denotes in its entirety a washing machine in accordance with the present invention.
  • the washing machine 1 is preferably a washing machine or a washer-dryer.
  • the washing machine 1 may be a front loading washing machine or, alternatively, a top-loading washing machine.

  • the drum 20 is rotatably driven by suitable actuators, known per se and therefore not described in detail below.
  • a fluid which, depending on the single washing step, can include only water, or water mixed with one or more detergents.
  • An outlet conduit 40 is connected to the tub 10 for conveying the fluid out of the tub 10 itself; the outlet conduit 40, also called exhaust bellows, is connected to a drain pump (not shown) in turn connected to a further outflow conduit (also not shown), so as to exhaust the fluid at the end of predetermined washing or rinsing steps.
  • the outlet conduit 40 comprises a main body 30 and an end portion 50.

  • volute 62c wherein the impeller of the recirculation pump 62 is mounted, is formed enbloc with a protective element or cover 62d, which protects the circulation pump 62 itself from any water leakage, and therefore assigns particular safety to the washing machine 1.

  • a switch (not shown), comprising for example a solenoid or a thermal actuator.
  • This diverter can be driven in at least two operating configurations: in a first configuration, it allows a flow of fluid within the second conduit 63 (from the recirculation pump 62 to the tub 10), while in the second configuration it diverts the flow to an auxiliary conduit (not shown), which carries the fluid up to an upper end of the tub 10. In this way the fluid can be sprayed inside the tub by a different position, for example in the vicinity of the upper portion of the gasket surrounding the porthole.
  • the diverter is suitably driven by the electronic control system of the washing machine 1, for example time-based or depending on the measurements performed by a sensor capable of generating signals representative of the level of water inside the tub.
  • the control technique provides that a limited amount of water should be retained in the lower part of the tub 10 (in correspondence of a resistor, not shown, used to heat water); when the existing water exceeds a predetermined threshold, the diverter is controlled so as to interrupt the recirculation (that through the second conduit 63 enters again the fluid in the lower part of the tub 10), and to divert the flow toward said auxiliary conduit.
  • the washing fluid is inserted into the tub 10 and the drum 20, comprising water and one or more detergent substances.
  • Such fluid tends to accumulate on the bottom of the tub 10, in particular near said back surface 10a of the tub 10 itself.

  • the fluid is made to slide in the recirculation circuit 60, by means of the first conduit 61, the recirculation pump 62 and the second conduit 63.
  • the activation of the recirculation pump 62 for each cycle occurs after about 5 minutes, during which a water heating step is carried out; and the pump 62 is activated when it reaches a predetermined target temperature.
  • the recirculation pump 62 then remains active for the next 15-20 minutes. Thereafter, it is activated for about 30 seconds at regular intervals of about 10 minutes, until the conclusion of the mechanical washing. It should be noted that the periods can vary slightly depending on the cycle run.
  • the recirculation circuit 60 is also active during the rinsing phases: in particular for a time of about 30 seconds during the exchange time of each rinsing, and at the end of the final spin during unloading.
  • the invention achieves important advantages.
  • the washing machine according to the invention has a simplified structure, which can be easily and quickly assembled.
  • a further advantage consists in the fact that the washing machine according to the invention is able to optimize the cleaning action of the washing fluid by means of its recirculation circuit, since it obtains a premature mixing in the water of the washing agent, so that it can be effective in a quicker time.
