Definitions

  • the present invention relates to a washer-dryer machine comprising a heat pump for realising a drying function.
  • Washer-dryer machines combine a laundry washing machine and a laundry drying machine in one appliance having the size of a stand-alone washing machine.
  • washer-dryer machines using heat pump technology for dehumidifying the process air
  • these known washer-dryer machines comprise a heat pump provided with an evaporator, arranged in the air duct for cooling and dehumidifying hot air exiting a laundry treatment chamber, and with a condenser, arranged in the same air duct, downstream of the evaporator, for heating air before admitting it into the laundry treatment chamber.
  • a drawback of these known washer-dryer machines is that lint/fluff removed from the laundry by the process air can settle on the evaporator, reducing its heat-exchanging surface, and therefore its performances. There is also the risk that lint/fluff settled on the evaporator could catch fire due to the high temperature of the air flux exiting the laundry treatment chamber and passing through the evaporator.
  • some known washer-dryer machines using heat pump technology are provided with a lint/fluff filter placed in the air duct, upstream of the evaporator, in order to catch lint/fluff carried by process air, so as to try to avoid that this lint/fluff can reach the evaporator.
  • lint/fluff in particular small fibres and particles, may cross the filter without being trapped, in which case this lint/fluff may settle on the evaporator, with the above mentioned risks.
  • a washer-dryer machine comprising a heat pump for treating (i.e. heating and also cooling and dehumidifying) process air, in which the evaporator of the heat pump is arranged in such a way that during a washing cycle the washing liquid present in the machine at least partially submerges the evaporator, so as to at least partially wash the latter and at least partially remove fluff/lint from this evaporator, the latter is kept free/clean from lint/fluff, without requiring a manual cleaning performed by the user.
  • a washer-dryer machine comprising:
  • the evaporator is arranged in such a way that during a washing cycle the washing liquid present inside the tub and/or inside the air duct and/or draining channel at least partially submerges the evaporator, so as to at least partially wash the latter and at least partially remove fluff/lint from the evaporator.
  • the washing liquid reaches the evaporator and cleans it from the lint or fluff. A very comfortable, easy and secure cleaning of the evaporator is therefore possible.
  • the evaporator is arranged in such a way that during a drying cycle the liquid optionally present inside the tub and/or inside the air duct and/or the draining channel does not submerge the evaporator.
  • the evaporator can carry out its function properly.
  • the process air passes the evaporator, where liquid contained in process air condenses.
  • the condensed liquid drops back into the draining channel.
  • the washer-dryer machine comprises a lint/fluff filter arranged in such a way to trap fluff or lint exiting the laundry treatment chamber and moving towards the evaporator through the air duct, wherein the filter is arranged in such a way that during a washing cycle the washing liquid present inside the tub and/or inside the air duct and/or the draining channel at least partially submerges the filter, so as to at least partially wash the latter and at least partially remove fluff/lint from the filter.
  • the liquid level reaches the filter and covers it, washing away and cleaning the filter from lint or fluff which was collected there during the drying mode.
  • the fluff or lint is transported away. In this way, the filter is cleaned after each washing cycle.
  • the filter is arranged in such a way that during a drying cycle the liquid optionally present inside the tub and/or inside the air duct and/or the draining channel does not submerge the filter.
  • the filter carries out its function without being impeded or covered by the washing liquid.
  • the washer-dryer machine comprises a level sensor, connected to a control device of the washer-dryer machine, for detecting the liquid level inside the draining channel and/or inside the air duct.
  • control device is configured in such a way that, if, during a drying cycle, the liquid level inside the draining channel and/or inside the air duct reaches a prefixed threshold value, the control device activates the draining pump for draining at least part of the liquid present inside the draining channel.
  • the laundry treatment chamber is connected to the draining channel via a first coupling joint, the draining channel and the coupling joint being arranged in such a way that, once a liquid has entered the draining channel and has at least partially filled the first coupling joint, the latter can't be fully emptied by operating the draining pump, so that liquid present in the coupling joint impedes air contained in the laundry treatment chamber from reaching the draining channel via the first coupling joint.
  • the washer-dryer machine comprises also an auxiliary cleaning system adapted for washing one or more components (e.g. the evaporator and/or, if provided, the filter) of the washer-dryer machine.
  • an auxiliary cleaning system adapted for washing one or more components (e.g. the evaporator and/or, if provided, the filter) of the washer-dryer machine.
  • auxiliary cleaning system may advantageously comprise an auxiliary duct coupled in fluid connection with a first nozzle arranged such that a jet of liquid sprayed from the first nozzle cleans the evaporator.
  • the auxiliary cleaning system may advantageously comprise an auxiliary duct coupled in fluid connection with a second nozzle arranged such that a jet of liquid sprayed from the second nozzle cleans the filter.
  • Providing an auxiliary cleaning system allows cleaning the evaporator and/or, if provided, the filter, independently from performing the washing cycle.
  • the cleaning procedure can be carried out at each desired time, when it is necessary. Further the cleaning procedure can be carried out using tap water.
  • control device of the washer-dryer machine is configured for providing an alarm signal to inform a user about the necessity to clean the filter after the washer-dryer machine has performed a prefixed number of consecutive drying cycles.
  • control device is configured for automatically loading a washing liquid inside the tub, so as to at least partially submerge the evaporator and at least partially wash the latter in such a way to at least partially remove fluff/lint from the evaporator, after the washer-dryer machine has performed a prefixed number of consecutive drying cycles.
  • the control device is configured for automatically loading a washing liquid inside the tub, so as to at least partially submerge the filter and at least partially wash the latter in such a way to at least partially remove fluff/lint from the filter, after the washer-dryer machine has performed a prefixed number of consecutive drying cycles.
  • the drum comprises, on its lateral surface, an opening arranged in such a way that it can face the filter when the drum is in a prefixed angular position, wherein the opening allows accessing the filter for its manual maintenance, and wherein the opening is closed by a removable closure device.
  • the filter can be reached manually for being cleaned manually or for being detached from its seat in the air inlet channel. Easy and comfortable access is provided to the filter in this way.
  • the removable closure device may advantageously be a lifter adapted to engage the laundry during the rotation of the drum, which can be pivoted with respect to the drum for providing access to the opening.

  • a fan 7 is arranged in the air duct 16 for creating an air flow that passes through the evaporator 6, then through the condenser 102, then enters the tub 2 via the air inlet 17 (so as to contact the laundry 25 contained in the drum 3 and removing the moisture from such laundry 25), and exits the tub 2 via the air outlet 8.
  • a lint/fluff filter 9 is provided at the air outlet 8 for trapping fluff or lint exiting the laundry treatment chamber 4 and moving towards evaporator 6; filter 9 may have also a different position in the air duct 16, provided that it is placed upstream the evaporator 16, i.e. in a position in which air exiting laundry treatment chamber 4 passes through the filter 9 before contacting the evaporator 6.
  • Washer-dryer machine 1 comprises also a washing liquid inlet circuit, not illustrated, adapted to bring a washing liquid (i.e. water or water mixed with a washing/rinsing product, for example a detergent or a laundry softener) into the tub 2.
  • Washing liquid inlet circuit may advantageously comprise a series of ducts connectable to the water mains, valves, a detergent drawer, etc.
  • the washer-dryer machine comprises also a draining channel 11, fluidly connected to the laundry treatment chamber 4, i.e. to the tub 2, and comprising a draining pump 15, for draining washing liquid from the laundry treatment chamber 4.
  • the draining channel 11 is fluidly connected to the tub 2 via a coupling joint 13, preferably comprising a flexible or rigid conduit.
  • the coupling joint 13 is preferably coupled to the tub 2 at the lowermost position of the tub 2 or the tub shell adjacent to a sump 24 advantageously formed in the tub 2.
  • liquid which is collected in the lowermost position of the tub 2 or in the sump 24 (if provided) flows through the coupling joint 13 into the draining channel 11.
  • the draining channel 11 and the air duct 16 are in fluid communication one another, in such a way that moisture condensed in the evaporator 6 during the drying cycle goes in the draining channel 11 and can be drained away via the latter.
  • washer-dryer machine 1 comprises also a level sensor 10 (for example a floating level sensor), connected to a control device of the washer-dryer machine 1, schematically represented in enclosed figures and numbered 103 (connection is not represented in enclosed figures), adapted for detecting the liquid level inside the draining channel 11 and/or inside the air duct 16 (which, being fluidly connected to the draining channel 11, can be partially filled with washing liquid and/or condensed liquid).
  • level sensor 10 is arranged in a conduit 12 connecting the draining channel 11 to the aid duct 16.
  • the control device 103 is configured in such a way that, if, during a drying cycle, the liquid level detected by the level sensor 10 is higher than a prefixed threshold value (which may be memorized in the control device 103), the control device 103 activates the draining pump 15 for draining at least part of the liquid present inside the draining channel 11.

  • the moisture or humidity that is absorbed or dissolved in the process air condenses and regains a liquid state.
  • the moisture or humidity that has become fluid now drops down into the draining channel 11 via the conduit 12.
  • the process air passes the air duct 16 in the direction of the air flow AF and is redirected to the air outlet 17 again.
  • the passage which is formed by the coupling joint 13 serves as a sort of siphon for avoiding that during a drying cycle a part of the process air can be drained outside the machine via the draining channel 11.
  • this is obtained by positioning at least part of the pump 15 at a level at least slightly higher than the outlet region (i.e. the region connected to the draining channel 11).
  • FIG 2 schematically illustrates the washer-dryer machine 1 during a washing cycle.
  • Evaporator 6 is arranged in such a way that during a washing cycle the washing liquid (water or water mixed with washing/rinsing products) present inside the tub 2 and/or inside the duct 16 and/or the draining channel 11 at least partially submerges the evaporator 6, so as to at least partially wash the latter and at least partially remove fluff/lint from this evaporator 6.
