  • each heat pump device substantially makes use of a refrigerant circuit for effectively transferring thermal energy from a first side at a lower temperature (also referred to as cool side), to a second side at a higher temperature (also referred to as hot side).
  • a common type of heat pump device exploits physical properties of a refrigerant fluid (or refrigerant), which is made to flow in the refrigerant circuit, and comprises a compressor, a pressure-lowering device (e.g., an expansion valve), and a heat exchanger assembly - i.e. a first heat exchanger (where the refrigerant absorbs heat) and a second heat exchanger (where the refrigerant releases heat).
  • the air leaving the laundry chamber with decreased temperature and increased humidity (or dump air) with respect to the incoming hot air i.e., the drying air
  • the first heat exchanger where it is further cooled down and dehydrated, and then through the second heat exchanger where, upon reheating, it forms the hot drying air, thereafter the drying air is fed again inside the laundry chamber for evaporating moisture from the laundry load.
  • cooling capacity at cool side is not high enough to efficiently cool down the dump air, which results in overheating of the drying air at hot side.
  • an undesired overheating of the laundry appliance, and especially of electric/electro-mechanic/electronic components housed therein is typically experienced, which sets reliability issues.
  • An aspect of the solution according to one or more embodiments of the invention relates to a laundry appliance comprising a cabinet, a laundry chamber enclosed within the cabinet for containing laundry to be dried, and a worktop atop the cabinet.
  • the worktop integrates a drying process air circulation system adapted to continuously circulate process air through the laundry chamber.

  • the overflow-preventing system is in fluid communication with said further air passage.
  • said washing products dispensing arrangement comprises a downwards protruding pipe portion configured to be filled, during drying operation mode, with a predefined amount of water, so that when said amount of process air is passed through the washing products dispensing arrangement, fluff is held in the water.
  • the worktop houses, along the process air circulation system, first and second heat exchangers of a heat pump device, said air duct allowing the ambient air to enter the process air circulation system through an input region thereof in correspondence of the second or the first heat exchanger.
  • the worktop houses, along the process air circulation system, first and second heat exchangers of a heat pump device, said air duct allowing the ambient air to enter the process air circulation system through an input region thereof between the first and second heat exchangers.
  • said air duct comprises an enlarged portion acting as a resonant cavity suppressing/dampening acoustic waves within it caused by ambient air flow.
  • said air duct comprises first and second sound suppressing/dampening portions for suppressing/dampening acoustic waves caused by ambient air flow, the first and second suppressing/dampening portions being spaced apart from each other so as to define an air gap therebetween for ambient air flow.
  • said air duct comprises an air passage provided at a panel of said cabinet, said ambient air being admitted within the cabinet through said air passage and hence through said air duct.

  • a motor-driven fan 125 e.g . arranged downstream the second heat exchanger HE 2 .
  • the dump air leaving the laundry chamber 105 with decreased temperature and increased humidity with respect to the incoming hot drying air is first passed (through the return duct 115) through the first heat exchanger HE 1 , where it is further cooled down and de-moisturized (heat pump cool side).
  • the de-moisturized air is then passed through the second heat exchanger HE 2 (heat pump hot side), where it is heated-up, thereafter the corresponding hot de-moisturized air, i.e . the drying air, is fed again (through the delivery duct 110) into the laundry chamber 105.
  • the second heat exchanger HE 2 heat pump hot side

  • the secondary air ducts 130-330 have been illustrated as having same shapes and arrangements, but reciprocally different lengths (depending, in the example at issue, on the air circulation system 100-300 input regions which they are fluidly connected to), it being understood that shape, size and arrangement thereof, not limiting for the invention, may be chosen according to design options of the air circulation system 100-300 (as progressively detailed when introducing design issues thereof) and of the corresponding laundry appliance (as better detailed when discussing a practical implementation thereof).
  • the ambient air A AIR is allowed to enter through the air circulation system 400 input region in correspondence of the second heat exchanger HE 2 (as for Figure 1 embodiment).
  • a secondary output opening OUT 105,S of the laundry chamber 105 is provided for allowing an amount of dump air within it to leave the air circulation system 100-400 (and to vent, at least in part, outside the laundry appliance), so as to substantially compensate/balance the ambient air A AIR added thereinto.
  • the amounts of dump air allowed to leave the air circulation system 100-400 (hereinafter, compensation air C AIR ) and of ambient air A AIR allowed to enter thereinto should be made substantially equal ( e.g ., by properly shaping and sizing the secondary air duct 130-430 and the secondary output opening OUT 105,S one another).

  • a first covering panel 520 1 of the cover assembly 520 covers the base element 515 with the exception of the left corner region thereof - the space between the base element 515 ( i.e., the housing sections 515 HE1 , 515 HE2 ) and the first covering panel 520 1 delimiting an air path that substantially identifies, together with filter unit F air path, the main duct 430.
  • a second covering panel 520 2 is instead provided on the first covering panel 520 1 for aesthetical issues.
  • the base element 515 comprises, e.g . at a substantially central part of the housing section 515 HE2 , a base opening 525, which is fluidly connected to the fan 125 ( e.g ., rigidly fixed to the base element 515, underneath it) and to the delivery duct 110 for allowing the drying air to be supplied into the laundry chamber 105.
  • the base opening 525 opens down to a fan 125 input
  • the delivery duct 110 arranged underneath the base element 515 as well, has a first end connector (not visible) for connection with a fan 125 output, and a second end connector (for example, an elongated-shaped connector, as illustrated) for connection with an opening of a bellow (not shown) that, as usual in washer/dryers, seals gap between the drum and the access door 510.
  • the base element 515 also comprises, e.g . at the left corner region thereof, a further base opening 530, which allows connection of the return duct 115 (carrying the dump air within it) from the output opening OUT 105 of the laundry chamber 105 to the filter unit F.
  • the base opening 530 also allows passage of un-channeled air circulating within the washer/dryer 500 (outside the air circulating system).
  • the dump air leaving the laundry chamber 105 is first supplied (through the return duct 115) through the filter unit F, and the filtered dump air output therefrom is then passed through the first heat exchanger HE 1 , where it is de-moisturized (with the condensed moisture that is properly collected and drained by a slot grid 535 of the base element 515 on which the first heat exchanger HE 1 rests).
  • the de-moisturized air is then passed through the second heat exchanger HE 2 , where it is heated-up, thereafter the drying air is supplied again (through the base opening 525, the fan 125 and the delivery duct 110) into the laundry chamber 105 ( i.e., from a front thereof through the bellow opening).
  • the air duct 430 comprises an air passage 540 for allowing admission/access of ambient air A AIR into the washer/dryer cabinet 505.
  • air passage 540 may be provided at any suitable panel 505 T ,505 F ,505 S of the cabinet 505, and at any proper position thereof.
  • such air passage 540 is provided at the worktop 505 T , as the latter integrating the air circulation system within it (however, nothing prevents from providing the air passage 540 at the front 505 F or side 505 S panels, in which case joint members could be necessary for joining the air passage 540, at the front 505 F or side 505 S panels, to the input region of the air circulation system 400, at the worktop 505 T ).
  • the air passage 540 is provided at the base element 515 of the worktop 505 T .
  • the air passage 540 is configured as an air grid vertically extending (with respect to the floor where the washer/dryer 500 is intended to rest) between opposite top S TOP and bottom S BOTTOM surfaces of the base element 515 (however, any other configuration deemed suitable for the purpose can be conceived).
  • the air passage 540 is placed at a rear portion ( e.g ., at the right corner) of the base element 515 that, upon worktop 505 T mounting, protrudes with respect to washer/dryer 500 back. This generates a gap between the washer/dryer 500 back and a vertical wall (not shown) which the washer/dryer 500 is intended to lean against, which allows adequate ambient air A AIR intake.
  • Figure 5B also shows, at the left corner of the base element 515, a further air passage 545, similar to the air passage 540, configured to allow un-channeled air within the cabinet 505 to be vented outside the washer/dryer 500 (as indicated by arrows exiting from the worktop 505 T air passage 545).
  • Such un-channeled air may comprise (as in many washer/dryers) further ambient air intended to cool down the compressor heat pump, and/or (as discussed above for some contemplated embodiments of the invention) the compensation air C AIR .
  • Air passage 540 arrangement should take into account air passage 545 arrangement.
  • the air passages 540 and 545 are arranged far enough to substantially avoid, or at least limit, that the air exiting the air passage 545 gets back into the air passage 540 thereby frustrating drying air cooling.
  • the first 445 1 and second 445 2 sound suppressing/dampening portions are arranged on the top surface S TOP of the worktop base 515 such that the ambient air A AIR , after entering the air passage 540, are channeled within the air gap defined by them.
  • the ambient air A AIR is then channeled into a bottleneck portion 550 of the base element 515 fluidly connecting the air gap to the housing section 515 HE2 (or to any other input region of the air circulation system 400, as discussed above), thereafter mixing between ambient air A AIR and drying air takes place.
  • the air passage 540, the air gap between the first 445 1 and second 445 2 sound absorbing portions and the bottleneck portion 550 act, as a whole, as the secondary air duct 430.
  • Arrangement of the air passage 540, as well as sizing and shaping of the air gap and of the bottleneck portion 550, are adapted to meet specific design options.
  • a sufficiently narrow and curved bottleneck portion (as the illustrated bottleneck portion 550), is able to prevent the drying air from spreading without control through the secondary air duct 430.
  • air passage 540, air gap and/or bottleneck portion 550 reciprocal arrangements, shaping and sizing could meet local pressures differences issues.
  • a pressure at the input region of the air circulation system 100 sufficiently lower than ambient pressure would allow ambient air A AIR taking/drawing by pressure unbalance, without requiring any additional fans.
  • the drying air/ambient air A AIR mixture is supplied to the laundry chamber 105, thereafter at least a part thereof (compensation air C AIR ) is vented outside the washer/dryer 500 through the washing products dispensing arrangement 435 and the loading tray 440 connected thereto (as discussed herebelow).
  • At least part of the compensation air C AIR leaving the laundry chamber 105 and flowing, through the dispensing arrangement 435, up to the loading tray 440 is vented through interstices of the loading tray 440 (not distinguishable) allowing opening/closing movements thereof.
  • compensation air C AIR venting is further achieved by means of an overflow-preventing system typically provided in washer/dryers for preventing liquids (e.g ., washing products and/or water) from overflowing out of the washer/dryer 500, for example through the loading tray 440, upon a fault occurrence (e.g ., water pump closure fail).
  • the overflow-preventing system per se well known in the art, comprises a draining channel 555 (part of which visible in Figure 5D ), preferably arranged at a side of the loading tray 440 and at predefined height.
  • the liquids When, as a result of a fault, the liquids, rising up within the laundry chamber 105, reach the loading tray 440, they reach a limit level (given by said predefined height), and the exceeding liquids are drained (through the draining channel 555) to a proper liquid container (not shown) arranged within the washer/dryer 500, where a liquid detection system (also not shown) is provided.
  • the liquid detection system Upon detection of a predefined liquids amount, the liquid detection system completely stops washer/dryer 500 operation, thereby preventing liquids from overflowing out of the washer/dryer 500 via the loading tray 440 and from causing flooding of the user premises where the washer/dryer 500 is placed.
  • the compensation air C AIR (or a part thereof) can flow through the overflow-preventing system, and vent inside the washer/dryer 500.
  • the overflow-preventing system is in fluid communication with the air passage 545, such that, compensation air C AIR (or a part thereof) which has been vented inside the washer/dryer 500, can be exhausted outside the washer/dryer cabinet 505.
  • the fluff-laden compensation air C AIR leaving the laundry chamber 105 and flowing up the washing product dispensing arrangement 435 may cause fluff to accumulate within, thereby dirtying, the loading tray 440. Such fluff may mix to washing products and negatively affect washing operation of the washer/dryer 500.
  • the washing products dispensing arrangement 435 preferably in the form of a pipe, is preferably provided with a downwards protruding pipe portion 560 ( Figure 5D ) adapted to be at least partially filled, during drying operation mode, with a proper amount of water (a water well is thus formed along the compensation air C AIR path).
  • a water well is thus formed along the compensation air C AIR path.
  • any component thereof may be separated into several elements, or two or more components may be combined into a single element; in addition, each component may be replicated for supporting the execution of the corresponding operations in parallel.
  • any interaction between different components generally does not need to be continuous (unless otherwise indicated), and it may be both direct and indirect through one or more intermediaries.
