Definitions

  • the present invention refers to a washing machine
  • washing machines both “simple” washing machines (i.e. washing machines which can only wash and rinse the laundry) and washing-drying machines (i.e. washing machines which can also dry the laundry), usually comprise an external casing provided with a loading/unloading door which allows the access to a washing tub containing a rotary perforated drum in which the laundry to be washed can be loaded.
  • the drum is provided with some lifters adapted to improve the stirring of the laundry during the rotation of the drum; the lifters are substantially prismatic elements fixed to the inner lateral surface of the drum and positioned with their longitudinal axis substantially parallel to the longitudinal axis of the drum.
  • first type of known washing machines called “front-loading” washing machines
  • front-loading washing machines on the frontal wall of the external casing it is obtained a first opening, adapted for allowing the loading/unloading of the laundry, facing a second opening obtained in the tub and a third opening obtained in one base of the drum; the borders of these first and second openings are connected by a flexible bellows.
  • the first opening is closable by a porthole hinged to the frontal wall of the external casing.
  • top-loading washing machines on the upper surface of the external casing it is obtained a substantially rectangular first opening, facing a corresponding second opening obtained in the lateral surface of the tub; also in this case the borders of the first and second openings are connected by a flexible bellows.
  • the first opening is closable by an external lid hinged to the upper surface of the external casing.
  • a third opening is obtained, adapted, when it is positioned in correspondence to the first and to the second openings, to allow the loading/unloading of the laundry in the drum.
  • the third opening is closable by one or, most frequently, by two internal lids, which, when closed, substantially constitute a portion of the cylindrical lateral surface of the drum; these internal lids, when opened and placed in the loading position, engage the border of the first opening obtained in the external casing, partially exiting from the latter, and limiting in this way the rotation of the rotary drum during the opening of the latter.
  • Both the above mentioned front-loading and top-loading washing machines comprise a water outlet circuit, typically comprising a drain pump and some draining pipes, adapted to drain water from the tub after the washing and rinsing phases.
  • the water outlet circuit usually comprises filtering means, placed between the bottom of the tub and the drain pump, adapted to retain all undesirable bodies (for example buttons came off from the laundry, coins erroneously introduced into the washing machine, etc.) passed through the holes located on the periphery of the drum, or fell to the bottom of the tub by passing between the drum and the tub, which could damage or obstruct the pump.
  • filtering means placed between the bottom of the tub and the drain pump, adapted to retain all undesirable bodies (for example buttons came off from the laundry, coins erroneously introduced into the washing machine, etc.) passed through the holes located on the periphery of the drum, or fell to the bottom of the tub by passing between the drum and the tub, which could damage or obstruct the pump.
  • the most common of these filtering means consists of a cylindrical box attached to the base of the washing machine and containing a removable filter fluidly connected upstream of the drain pump.
  • This box containing the filter is accessible through a quick-removable plug that allows the filter to be removed and cleaned, the plug being hidden by a gate located, depending on the case, on the front or back wall of the external casing of the washing machine.
  • washing machines of the top-loading type comprising a draining sump obtained on the lower region of the lateral surface of the tub, and fluidly communicating with the internal of the latter; a filter is placed in a housing obtained inside the draining sump, and the drain pump is attached to the tub in the extension of this draining sump.
  • one of the above mentioned lifters arranged longitudinally to the drum and protruding internally to the latter, is removable, in order to allow the access to the underlying housing, and the removal/ repositioning of the filter, for example for its cleaning.
  • a prior art washing machine containing a filter used to prevent residual particles of dirt from reaching and obstructing the pump and its drainage duct, and which can be removed from the internal of the tub, for inspection, cleaning and replacement, is illustrated, for example, in GB 1197919 , which discloses a washing machine comprising a tank (i.e. a tub) for liquid with an opening in its base, a draining pump connected by a pipe to the opening of the tank, and a basket (i.e. a rotary drum) disposed within the tank; a cup-like filter element having filter openings in its side wall is removably seated in the tank opening, and an opening is provided in the basket, provided with a removable closure, to provide access to the filter element.
  • a tank i.e. a tub
  • a draining pump connected by a pipe to the opening of the tank
  • a basket i.e. a rotary drum
  • FR 2190966 discloses a top-loading washing machine comprising a tub containing a rotary drum provided, on its lateral surface, with a first door, adapted for loading/unloading the laundry, and with a second door, disposed opposite to the first door and adapted for allowing the recovering of linen which would have slipped between the tank and the drum.
  • a connector is fixed to the bottom of the tub, such connector being provided, at his inferior region, with a duct adapted to receive one of the extremities of a discharging pipe.
  • a housing is provided in the connector, adapted to receive a filter accessible by simultaneously opening the two doors of the drum.
  • EP 1 849 904 discloses a top-loading washing machine comprising a draining filter access apparatus integrated in a lifter diametrically opposite to the drum access door (i.e. to the internal lid allowing the access to the drum).
  • the draining filter access apparatus comprises a body, including an opening aligned with an opening of the same shape and dimensions made in the body of the drum, and a lid, hinged to the body and locking on the body by a simple ratchet mechanism.
  • the rotation allowed to the rotary drum is limited by the engagement of the internal lids with the border of the opening obtained in the external casing; the position of the opening lifter with respect to the drum is set in such a way that, when the washing machine is in the loading position, the opening lifter is placed approximately above the filter housing, in a position that allows placing the opening lifter above the filter housing by at most a small rotation of the drum. In this way, when the inner lids are in the loading position, the user has to apply at most a small rotation to the drum in order to align the latter with the tub, thus allowing the access to the housing of the filter.
  • the drum can freely rotate with respect to the tub even if the porthole is opened, and therefore the setting of the angular position of the drum in which the opening lifter is aligned with the underlying filter housing, necessary both when the filter has to be removed and when the filter has to be repositioned after cleaning, is more complicated and time expensive with respect to the top-loading solution.
  • the drum can be rotated even during the removal and during the repositioning of the filter, with the consequent risk of injuring the user, and/or of breaking the filter.
  • the aim of the present invention is therefore to obtain a washing machine which facilitates the access to the filter, so as, for example, to facilitate and to speed up the removing/repositioning of such a filter from/to the housing associated to the tub, and/or the cleaning and/or the inspection of such a filter.
  • Another object of the invention is to obtain a washing machine which facilitates the reaching of the angular-positioning of the drum allowing the access to the filter.
  • Another object of the invention is to obtain a washing machine which allows a safe removing/repositioning and/or clening and/or inspecting of the filter.
  • the Applicant has found that by the use of locking means adapted to lock the rotation of the drum of a washing machine with respect to the tub, when an opening, obtained in a lateral surface of the drum, faces a housing for a filter adapted to impede the passage of bodies of fixed dimensions from the tub to a draining circuit, and/or by the use of locking means adapted to impede the opening of a closing device adapted for selectively closing the opening when the opening doesn't face the housing, and to allow the opening of the closing device when the opening faces the housing, it is possible to have an easy and fast access to the filter, for example for its removal/repositioning from/to the housing and/or for its cleaning and/or inspecting.
  • a washing machine comprising:
  • the washing machine 1 according to the invention which is illustrated in the enclosed Figures is advantageously of the front-loading type; even if from the following description it will be clear that the advantages of the invention can be particularly appreciated in the case of a front-loading washing machine, the invention is however applicable, substantially without any substantial modification, to a top-loading washing machine.
  • the invention can be applied, substantially without any substantial modification, both to a "simple" washing machine (i.e. a washing machine which can only wash and rinse the laundry) and to a washing-drying machine (i.e. a washing machine which can also dry the laundry).
  • a "simple" washing machine i.e. a washing machine which can only wash and rinse the laundry
  • a washing-drying machine i.e. a washing machine which can also dry the laundry.
  • the washing machine 1 according to the invention, schematically represented in Figure 1 , comprises an external casing 2 in which frontal wall 2a an access opening 3 is obtained, provided with a loading/unloading door 4, which allows the access to a washing tub 5, contained in the external casing 2; the washing tub 5 contains a rotary perforated drum 6 in which the laundry to be washed, not illustrated, can be loaded (in the enclosed Figures, the holes obtained in the lateral surface of the rotary perforated drum 6 have not been represented).
  • the tub 5 is connected the external casing 2 via a flexible bellows 7, connected between the frontal, opened, surface of the tub 5 facing the access opening 3, and the border of the latter.
  • the washing machine 1 comprises a water inlet circuit 8 adapted to feed water and washing/rinsing products into the tub 5; the water inlet circuit of a washing machine is well known in the art, and therefore will not be described in detail.
  • the washing machine 1 comprises a draining sump 9, obtained preferably on the lateral surface 5a of the tub 5, fluidly communicating with the internal of the tub 5, and fluidly connected to a draining circuit 10 adapted to drain the washing/rinsing liquid (i.e. water and water mixed with washing and/or rinsing products) from the tub 5.
  • the draining circuit 10 comprises a draining pump, not illustrated, and one or more draining pipes, adapted to drain water from the tub after the washing and rinsing phases; the draining circuit of a washing machine is well known in the art, and therefore will not be described in detail.
  • the draining circuit 10 can be also provided with a recirculation circuit, adapted to drain the washing/rinsing liquid from the bottom of the tub 5, and to re-admit such liquid into an upper region of the tub, for improving the wetting of the laundry.
  • a recirculation circuit adapted to drain the washing/rinsing liquid from the bottom of the tub 5, and to re-admit such liquid into an upper region of the tub, for improving the wetting of the laundry.
  • the recirculation circuit of a washing machine is well known in the art, and therefore will not be described in detail.
  • draining sump 9 is placed in the lower region of the tub 5, so that the liquid contained in the latter can be conveyed by gravity towards this draining sump 9, and therefore to the draining circuit 10.
  • the draining sump 9 is obtained in a single-piece construction with the lower region of the tub 5, advantageously by moulding of a plastic material.
  • the draining pump of the draining circuit 10 comprises an impeller, not illustrated, housed in a body obtained in a single-piece construction with the tub 5 and/or with the sump 9.
  • the draining sump 9 is provided with a housing 11 for a filter 12 adapted to impede the passage of bodies of fixed dimensions from the tub 5 to the draining circuit 10 (and therefore to the pump of the latter).
  • bodies can be, for example, buttons came off from the laundry, coins or other little objects contained in the pockets of trousers or other clothes and erroneously introduced into the washing machine 1, etc.
  • the filter 12 can be extractable from the housing 11, as in the embodiments illustrated in the enclosed figures, or alternatively, in another embodiment, not illustrated, the filter 12 can be fixed to the housing 11 or obtained in a single-piece construction with the latter.
  • the filter 12 is substantially box-shaped and is provided, on its lateral surface, with a plurality of holes 13 (or apertures) adapted to allow the passage of liquids, but to avoid the passage of objects (e.g. coins or buttons) whose dimensions are higher than a prefixed value depending on the dimensions of the holes 13.
  • objects e.g. coins or buttons
  • the filter 12 is arranged in such a way that, when it is positioned into the housing 11, all the liquids entering the draining sump 9 have to pass through this filter 12 before going to the draining circuit 10; in this way bodies like buttons, coins, etc, contained in the washing or rinsing water, are trapped in the filter 12, and don't reach the draining circuit 10.
  • the filter 12 can be removed from the housing 11, for example for its cleaning, and it can be afterwards repositioned in the housing 11.
  • the filter 12 is fixed to the housing 11 in a permanent way, or it is a single-piece construction with the housing 11, and therefore it can't be removed from the housing 11; in this case a user can perform the cleaning of the filter 12 directly in the housing 11. It is clear that in the case in which the filter 12 is a single-piece construction with the housing 11, the filter and the housing partially or totally coincide.
  • the drum 6 is provided, on its lateral surface 6a, with an opening 14, adapted for allowing the access to the housing 11 of the draining sump 9, so as to allow acceding to the filter 12, for example for removing/repositioning and/or cleaning and/or inspecting the latter, when the drum 6 is positioned in such a way that this opening 14 faces the housing 11.

  • the lifter 16 operates as a traditional lifter, and is therefore useful for improving the stirring of the laundry during the rotation of the drum 6.
  • the closing element of the closing device 15 is a lifter 16
  • the closing device 15 could comprise, instead of a lifter 16, another suitable closing element (for example a lid or a porthole) adapted to selectively close the opening 14.
  • the closing element could be pivoted on the lateral surface 6a of the drum 6, or to a frame 17 fixed to the latter (as in the embodiments illustrated in the enclosed Figures); in another embodiment, not illustrated, the closing element could also be slidably associated to the drum, or it can be associated to the drum in a completely removable way.
  • a lifter 16 can be referred, substantially without modifications, to another suitable closing element (for example a lid, a porthole, etc.).

  • the lever 33 is preferably provided with elastic means, not illustrated, such as a spring, which allows a stable positioning of the lever 33 in two distinct angular positions, one, called external position and illustrated in Figure 11 , in which the pin 20 is positioned at an higher distance from the underlying tub 5, and the other, called internal position and illustrated in Figure 12 , in which the pin 20 is positioned at a lower distance from the underlying tub 5.
  • elastic means not illustrated, such as a spring
  • the closing device 15 comprises a locking/unlocking device adapted for locking/unlocking the lifter 16 in/from the closed position; in this case the locking/unlocking device comprises a second end 33b of the lever 33, which is substantially "U-shaped", in order to engage and lock, when the lifter 16 is in the closed position and the pin 20 is in the external position, a second arm 34 protruding from the lifter 16, such as to lock the lifter 16 in the closed position.
  • the pin 20, the first and second extremities 33a and 33b of the lever 33, and the second arm 34 are arranged in such a way that by manually lifting the lifter 16, the consequent movement upwards of the second arm 34 causes the lever 33 to rotate in such a way that its first end 33a pushes the pin 20 towards the tub 5.
  • the length of the pin 20 is such that if the drum 6 is rotated in such a way that the pin 20 isn't positioned in correspondence to the seat 19, and the user tries to lift the lifter 16, the pin 20 is pushed by the lever 33 towards the tub 5, and engages the lateral surface 5a of the latter, not allowing the full opening of the lifter 16.
  • the lifter 16 can therefore be opened only if the drum 6 is rotated in such a way that the pin 20 is positioned above the seat 19; in this position, by opening the lifter 16, the pin 20 is introduced in the seat 19, and locks the rotation of the drum 6; in this way it is very easy to find the correct angular position of the drum 6 which allows the opening of the lifter 16.
  • the pin 20 and the seat 19 are arranged in such a way that when the pin 20 is positioned in correspondence to the seat 19, the opening 14 provided in the drum 6 faces the housing 11, such that by opening the lifter 16 it is possible to accede to the housing 11.
  • a closing device 15 comprising, instead of the lifter 16, for example a lid, not illustrated, pivoted on a frame fixed to the drum 6, or directly to the latter.
  • FIG. 13 to 16 A fourth embodiment of the present invention is illustrated in Figures 13 to 16 .
  • the closing device 15 comprises a lifter 16 pivoted on two pivoting elements 21a, 21b protruding from a frame 17 fixed to the lateral surface 6a of the drum 6; obviously the frame 17 could be not provided, and the lifter 16 could be pivoted directly on pivoting elements provided on the lateral surface 6a of the drum 6.
  • the pin 20, preferably cylindrical or prismatic, is permanently associated to the drum 6 and to the frame 17 (only to the drum 6 if the frame 17 isn't provided), and it is accessible by the user towards a suitable opening 35 obtained in the lifter 16; advantageously the pin 20 can translate substantially radially respect to the lateral surface 6a of the drum 6.
  • the pin 20 is associated to a first end of 33a of a lever 33, pivoted on the frame 17 (or directly to the drum 6 if the frame 17 isn't provided).
  • the lever 33 is preferably provided with elastic means, not illustrated, such as a spring, which allows a stable positioning of such a lever 33 in two distinct angular positions, one, called external position and illustrated in Figure 15 , in which the pin 20 is positioned at an higher distance from the underlying tub 5, and the other, called internal position and illustrated in Figure 16 , in which the pin 20 is positioned at a lower distance from the underlying tub 5.
  • the closing device 15 comprises a locking/unlocking device adapted for locking/unlocking the lifter 16 in/from the closed position; also in this case the locking/unlocking device comprises a second end 33b of the lever 33, which is substantially "U-shaped", in order to engage and lock, when the lifter 16 is in the closed position and the pin 20 is in the external position, a second arm 34 protruding from the lifter 16, such as to lock the lifter 16 in the closed position.
  • the pin 20, the first and second extremities 33a and 33b of the lever 33, and the second arm 34 are arranged in such a way that when the pin 20 is moved towards the underlying tub 5, the second end 33b of the lever 33 rotates towards the lifter 16, so as to unlock the second arm 34; in this condition the lifter 16 can be manually lifted, or, if the pivoting means are provided with elastic means which tends to open the lifter 16, the latter is automatically opened as soon as the second arm 34 is unlocked.
  • the length of the pin 20 is such that if the drum 6 is rotated in such a way that the pin 20 isn't positioned above the seat 19, and the user tries to press the pin 20 towards the tub 5, for example by using a suitable tool, like a screwdriver or a pen, or also by a finger, the pin 20 translates towards the tub 5, and engages the lateral surface 5a of the latter, not allowing the unlocking of the second arm 34, and therefore not allowing the opening of the lifter 16.
  • the lifter 16 can therefore be opened only if the pin 20 is positioned above the seat 19; in this position, by pushing the pin 20 towards the tub 5, the pin 20 is introduced in the seat 19, locking the rotation of the drum 6, and contemporaneously the second arm 34 is unlocked, allowing the opening of the lifter 16. In this way it is very easy for a user to find the correct angular position of the drum 6 which allows the opening of the lifter 16.
  • the pin 20 and the seat 19 are arranged in such a way that when the pin 20 is positioned in correspondence to the seat 19, the opening 14 of the drum 6 faces the housing 11, such that by opening the lifter 16 it is possible to accede to the housing 11.
  • the closing device 15 comprises, instead of the lifter 16, for example a lid, not illustrated, pivoted on a frame fixed to the drum 6, or directly to the latter.
  • a fifth embodiment of the invention is illustrated in Figures 17 to 20 .
  • a cavity 36 adapted to temporarily lodge the pin 20, is provided in a frontal side 17a of the frame 17 opposite to the pivoting elements 21a, 21b on which the lifter 16 is pivoted (if the frame 17 isn't provided, the cavity 36 is obtained directly on the lateral surface 6a of the drum 6); advantageously the cavity 36 has an elongated shape.
  • the pin 20 is provided, in correspondence of a first end 20a, with a pivoting element 37, protruding from its lateral surface 20b opposite to the lifter 16.
  • a pivoting element 37 protruding from its lateral surface 20b opposite to the lifter 16.
  • an analogous further pivoting element protrudes from the lateral surface of the pin 20 facing the lifter 16.
  • a housing 38 for the pivoting element 37 is obtained at one side of the cavity 37, adapted to allow the rotation of the pin 20 with respect to the cavity 36 when the pivoting element 37 is positioned in the housing 38.
  • the pin 20 can rotate, with respect to the cavity 37, from an inner position, illustrated in Figure 18 , in which it is substantially fully contained in the cavity 37, to an outer position, illustrated in Figure 19 , in which it protrudes externally from the cavity 37, and is positioned substantially perpendicular to the cavity 37.
  • the housing 38 is opened towards the tub 5, in such a way that the pivoting element 37 can exit from the housing 38 when the pin 20 is in the outer position, as illustrated in Figure 20 .
  • the pin 20 After the pin 20 has been taken in the outer position, it can be pushed towards the tub 5, and, if the pin 20 is positioned above the seat 19, the pin 20 is introduced in the seat 19, locking the rotation of the drum 6 with respect to the tub 5.
  • the pin 20 isn't positioned above the seat 19, and a user, after taking the pin 20 in the outer position, tries to push the pin 20 towards the tub 5, the pin 20 engages the lateral surface 5a of the latter, and the rotation of the drum 6 isn't locked.
  • the pin 20 is provided with a handle 39 for its lifting.
  • the washing machine 1 comprises a locking/unlocking device adapted for locking/unlocking the lifter 16 in/from the closed position;
  • the locking/unlocking device comprise a lip 40 protruding from the end of the lifter 16 opposite to the pivoting elements 21a, 21b on which it is pivoted; opportunely the lip 40 is arranged in such a way that when the lifter 16 is in the closed position and the pin 20 is placed in the cavity 36 in the inner position (as illustrated for example in figure 18 ), the pin 20 leans on the lip 40, and the lifter 16 can't therefore be lifted; the lifter 16 can therefore be opened only after the pin 20 has been lifted and taken in the outer position.
  • the closing device 28, adapted for locking/unlocking the lifter 16 in/from the closed position comprises also the pin 20.
  • the closing device 15 comprises, instead of the lifter 16, for example a lid, not illustrated, pivoted on a frame fixed to the drum 6, or directly to the latter.
  • a pin 20 protrudes substantially radially from the lateral surface 6a of the drum 6, so as to engage a seat 19 provided on the lateral surface 5a of the tub 5.
  • the pin 20 protrudes from the rear end 6b of the drum 6, and the seat 19 is provided on the rear end 5b of the tub 5 facing the rear end 6b of the drum 6; in the same way in another embodiment, not illustrated, the pin 20 and the seat 19 can be associated respectively to a frontal end 6d of the drum 6, and to a frontal end 5d of the tub 5.
  • the drum can be taken and locked in the particular angular position in which the opening 14 of the drum faces the housing 11 for the filter, by a suitable programming of the electric drive which controls the electric motor adapted rotate the drum 6.
  • the electric motor can be directly mounted on the drum (or on a rotating shaft, not illustrated, associated to the drum), or it can also be connected to the drum via a suitable belt pulley.
  • the electric motor is a step motor (but it is clear that other kinds of electric motors could be used).
  • the electric drive of the electric motor of a washing machine is controlled by a programmable electronic board adapted to control the various functions of the machine (e.g. the washing phases, the rotary speed of the drum, etc.).
  • the electric motor rotates the drum 6 up to reach the angular position in which the opening 14 faces the housing 11, and locks the drum 6 in such a position, so as to allow the access to the filter, for example for its removing/repositioning and/or for its cleaning and/or inspecting.
  • the electronic board of the washing machine can be programmed in such a way that as soon as a user opens the loading/unloading door, the drum 6 is automatically rotated and locked by the electric motor in the position in which the opening 14 faces the housing 11, so as to allow the access to the filter.
  • the locking means comprise the electric motor and its electric drive.
  • the locking of the drum is obtained by other suitable means, comprising, for example, suitable brakes, not illustrated, controlled, for example, by the electronic board of the washing machine, and adapted to lock the drum, or the belt pulley, or the drum shaft.
  • the locking means comprise, for example a magnet, not illustrated, provided at/to the drum 6, preferably on its lateral surface 6a, and an electromagnet, also not illustrated, provided externally to the tub and preferably electrically powered by the electronic board of the washing machine.
  • the magnet and the electromagnet are arranged in such a way that when the electromagnet is electrically powered, it generates a magnetic field which causes the drum 6 to rotate until the magnet provided at/to the latter faces the electromagnet; opportunely the reciprocal position of the magnet and of the electromagnet is such that when the magnet faces the electromagnet, the opening 14 of the drum 6 faces the housing 11 of the tub, so as to allow the aces to the filter.
  • the electronic board is in this case programmed in such a way that after the detection, for example by a sensor or a switch, of a specific event (e.g. the opening of the loading/unloading door), the electromagnet is powered, so as to cause, as explained above, the rotation of the drum 6 and the positioning of the opening 14 in correspondence of the housing 11.
  • the electromagnet isn't electrically powered and controlled by the electronic board of the washing machine, but by a dedicated device, for example another electronic board, or simply by an electric switch connecting the electromagnet to a power source; in this last case, a user can act on the switch in order to activate the electromagnet and to cause the rotation of the drum.
  • a washing machine which, thanks to the locking means which impede the rotation of the drum with respect to the tub only when the opening obtained in the drum faces the housing for the filter, facilitates the access to the filter, and therefore the operations of removing/repositioning the filter from/to the housing, and/or the cleaning and/or the inspection of the filter.
  • the invention facilitates and speeds up the reaching the angular-positioning of the drum allowing the access to the filter housing.
  • the fact that the rotation of the drum is locked when the lift is opened and the opening of the drum is positioned above the filter housing allows a safe access to the filter, without the risk of injuring the user or to brake the filter.
