Definitions

  • the present invention relates to the laundry-drying machines of the domestic type, with a panel-type front door and extractable tank for collecting the condensation water.
  • Front-loading laundry-drying machines are known, both of the type in which the loading opening is closed by a porthole and of the type in which the loading opening is closed by a continuous panel which covers the entire front surface of the machine excluding the single control panel and a lower base.
  • EP-A-0 555 703 discloses an arrangement according to the preamble of claim 1.
  • the tank is provided, on its upper face, with a filling opening which freely faces, when the door is closed, a pipe for supplying condensation water, without the use of sealing connections or overflow pressure switches.
  • the cassette housing of the tank also constitutes a section of the drying circuit leaving the rotating basket for containing the laundry, which is closed by a perforated protection diaphragm and in which, interposed between diaphragm and collecting tank, there is accommodated a filter for catching fluff, which can be removed separately from said tank and cleaned easily.
  • a first seal arranged all around the loading opening ensures, when the door is closed, the sealing of the drying circuit from the outside.
  • a second seal arranged inside the loading opening, mates with the internal diaphragm, isolating the section of the drying circuit leaving the rotating basket from the volume of the basket.
  • the tank is provided with means which reduce to a minimum or eliminate the risk of overflows during handling of the tank.
  • the laundry-drying machine comprises essentially a rotating drum or basket 1 which holds the laundry, is set in rotation by a motor 2 and passed through by a flow of air which is introduced into the drum 1 by a centrifugal fan 3 and is subject to heating by heating elements 4.
  • the laundry contained in the drum 1 releases, by evaporation, the humidity which it contains to the flow of hot air.
  • the hot humid air leaves the drum through a filter 5 (which retains flying down and fluff) and is conveyed by an appropriate pipe entering a condenser 6 which is cooled by a flow of relatively cold air drawn in from the atmosphere by means of a centrifugal aspirator 7.
  • the vapour contained in the flow of hot air is condensed to liquid by cooling and collects in a condenser reservoir 8 arranged below the level of a door for closing the loading opening, while the dehumidified air leaving the condenser 6 is drawn by the fan 3 and made to recirculate in the drum 1, subject to reheating.
  • the flow of ambient air used for the condensation is on the other hand dispersed into the atmosphere.
  • the condensation liquid collected in the reservoir 8 is conveyed, by means of a pump 9, into a collecting tank 10 which is arranged at a higher level relative to that of the condenser.
  • a level sensor 11 acts if the level of liquid in the reservoir exceeds a predetermined value, stopping the operation of the machine.
  • the operation of the machine is controlled by a programmer 12 which is actuated by buttons or knobs 13 arranged on a front control panel 14.
  • the loading opening 16 in the front wall is defined by a collar 17 which extends internally from the front wall 15 to be connected, by a labyrinth seal, to a front rim 18 of the rotating drum 1.
  • aspiration openings 19 open, which are connected to an aspiration pipe 20 which conveys the humid air leaving the rotating drum to the condenser 6.
  • the external edge and the internal edge of the collar are expediently provided with a resilient seal 22, 23 respectively.
  • the door for closing the loading opening which is hinged on the front wall, is formed by a flat external front panel 24 and by an internal counter-panel 25 which has a flat frame which, when the door is closed, is juxtaposed to the seal 22 bringing about the sealed closing of the loading opening.
  • the counter-panel forms a sleeve 26 which projects internally and is accommodated in the collar of the loading opening and the external wall of which is juxtaposed, when the door is closed, to the seal 23.
  • a housing 27 or containing cassette Formed inside the sleeve is a housing 27 or containing cassette, which is generally cylindrical but can be prismatic, for a tank 10 for collecting the condensation water, which can be removed from the cassette in the direction of the housing axis represented by the arrow 28 and inserted by translation in the opposite direction.
  • a perforated cover 29 is hinged, which constitutes a separation diaphragm between the internal volume of the rotating drum 1 and the cylindrical housing 27 to prevent the penetration of the laundry to be dried into the housing 27 during operation of the machine.
  • a filter 5 for catching the down and fluff shed by the laundry is removably engaged.
  • the filter 5 is expediently provided with a knob 31 or equivalent means for its extraction from the cover 29 in the direction represented by the arrow 32.
  • the knob 31 also serves as a spacer and, by bearing against the wall of the tank 10, ensures the formation, between filter and tank, of an air chamber, through which the hot humid air which passes through the filter can flow towards the aspiration pipe 20, through expedient openings 34 formed in the lower wall of the sleeve.
  • the sleeve 26 is provided on its upper wall with a funnel-shaped opening 33 which brings the outside of the sleeve into communication with the internal housing 27 and, when the door is closed, faces the nozzle 21 for discharge of the condensation water.
  • the tank 10 is expediently provided with a handle 35 for extraction/insertion and, on its upper face, with a filling mouth 36 which, when the tank is inserted in its housing, is juxtaposed freely, in other words without any device for valve-type closing or sealed connection to a delivery pipe, to the funnel-shaped opening 33.
  • the filling mouth therefore functions jointly as a filling opening and a vent opening and prevents the tank becoming pressurized during filling.
  • the tank 10 is provided on one side and on the upper wall with a recessed groove 37 which extends from the filling mouth 36 to the lower wall of the tank in such a manner that, when the tank is full, the excess liquid conveyed into the tank can freely overflow from the mouth 36 and flow along the groove 37 to the lower wall of the sleeve 26 where, passing through the openings 34, it is conveyed into the condenser 6 and discharged into the reservoir 8.
  • the operation of the laundry-drying machine described is very simple: by opening the loading door, the operator can insert the laundry to be dried into the rotating drum, check that the filter 5 is clean and, if necessary, clean it by opening the cover 29 and removing the filter independently of the tank.
  • tank 10 expediently made to this end of transparent material, is empty and, if necessary, remove it and empty it.
  • the filter When the tank has been reinserted into its housing, the filter has been reinserted into the cover 29 and the cover has been reclosed, the door can be reclosed and the operation of the drier can be started.
  • the condensation liquid leaving the nozzle 21 is discharged into the housing 27 and, conveyed back into the condenser reservoir, brings about the action of the protection, in the same manner, at the very beginning of the drying operation.
  • the operator alerted by the action of the protection, can easily recognize, by opening the loading door, the full state of the tank or its absence from the housing.
  • the structure of the machine is therefore very simple and extremely reliable and at the same time particularly ergonomic and convenient to operate.
  • the removability of the filter independently of the collecting tank allows it to be handled easily, unaffected by the weight of the tank, for thorough cleaning, if necessary under a jet of water, without risk of damage.
  • the removal of the tank for emptying can be carried out without special precautions, except those which are necessary in order to avoid any overflows if the tank is completely full.
  • Figures 3, 4 and 5 represent a number of measures which reduce to a minimum or eliminate the risk of any overflows during removal of the tank.
  • the tank 10 is provided internally with an overflow tube 40 which is open on the lower wall of the tank and the top of which ends close to the handle 35 for extracting the tank from its housing. Since the handle is eccentric relative to the barycentric vertical axis of the tank, the tank tends, during its removal from the cassette housing, to rotate slightly to be arranged with its barycentre vertically aligned with the gripping handle.
  • the overflow tube 40 can advantageously be replaced by a siphon 41 which comes into action when the level of the liquid in the tank reaches the threshold 42 of the siphon and brings about the partial emptying of the tank to the level of the mouth 43 for feeding the siphon.
  • the mouth 36 for filling the tank 10 is provided with a funnel-shaped sleeve 44 which penetrates a convenient depth into the tank.
  • the maximum pressurization which can be exerted is determined in terms of water column, by the difference between the overflow level of the mouth 36 and the filling level of the tank.
  • vent opening 46 which is normally closed when the tank 10 is correctly installed in its housing by a resilient plug 47 arranged in the housing, on the first movement of the tank 10 for its removal, the opening 46 is opened, drawing back into the tank the liquid contained in the sleeve 44.
  • the resilient plug 47 can be mounted on the filter 5 and the vent 46 can be provided on the wall of the tank facing the filter in such a manner that opening the cover 29 brings about opening of the vent, still before the tank is removed from its housing.
  • Fig. 6 represents an alternative embodiment of the laundry-drying machine in Figs 1 and 2, in which, inside the front closing door, the counter-panel 25 forms a cassette 27 or pocket housing for the tank and filter, which is open at the top.
  • the perforated diaphragm 50 for clsing the cassette is an integral part and steady with the counter-panel itself.
  • the filter 5 provided with a spacing frame 30 and an upper handle 48, is arranged in the cassette 27 in an interposed position between the perforated diaphragm 50 and the tank 10 which is provided with an upper handle 49 and a filling mouth 36.
  • the tank is expediently shaped to allow its removal from the cassette by slight rotation and translation upwards, subject to removal of the filter 30, so as to utilize (as in the case of Figs 1 and 2) the volume offered by the thickness of the closing door.
  • the filter is inspected upon each operation to remove the tank, avoiding subsequent disadvantages (reduction of the drying efficiency, greater wear of the fan and overheating of the recirculation air).
