Definitions

  • the present invention relates to a system to control the closing of a door of a household appliance, in particular for a washing machine, such as a dishwasher.
  • a door which is movable relative to the casing so as to open and close an access opening, through which the inner chamber is able to communicate with the outside of the household appliance.
  • these systems comprise an engagement element, intended to be fitted on one between the casing and the door, and a retaining element, which is intended to be fitted on the other one between the door and the casing.
  • the retaining element is intended to hold the engagement element in a releasable manner, so as to constrain the door to the casing, when the household appliance is being used.
  • the coupling between the engagement element and the retaining element takes place by means of the action of a user, who brings them closer by manually pushing the door against the casing, so as to obtain a complete closing.
  • the uncoupling between the engagement element and the retaining element usually takes place by means of the action of the user, who can act upon suitable control interfaces (for example, provided on the front wall of the door or on the front or upper face of the casing), which activate inner mechanisms of the retaining element, which release the engagement element from the retaining element.
  • EP 1 733 675 A2 discloses a dishwasher comprising a plate connected to the door latch which can be extended across the gap between the top of the open door and the body of the machine. It can take up two positions, in one of which the gap is wider than the other. It is extended by a motor controlled by a proximity switch.
  • An independent claim is included for a method for operating a dishwasher program, in which the door is opened to produce the narrow gap and then moved to the position with the wider gap, according to the frying of the dishes in the machine.
  • EP 2 193 740 A1 discloses a machine which has a drive unit, i.e. electric motor, controlled by a control unit.
  • a linear moving unit is driven by the drive unit for positioning a door.
  • a locking device i.e. U-shaped clamp, is arranged at the door and stays in effective connection with the linear moving unit for positioning and locking the door.
  • Another drive unit i.e. hub magnet, is arranged on the moving unit.
  • a control rod is fixed on the latter drive unit in a linear movable manner such that the control rod is moved in and out for locking or unlocking the moving unit in the locking device. It is also disclosed a method for opening a door of a cleaning machine.
  • EP 0 711 528 A1 discloses a a method and a device for carrying out the method for drying crockery in a dishwasher with a rinse container closeable by means of a door. By means of two or three successive different method steps, the drying is improved.
  • the method steps include a drainage phase, a drying phase with blower or condenser and an automatic, partial opening of the door.
  • An object of the present invention is to provide a system to close a door of a household appliance, which is improved and, at the same time, can be produced in a simple and economic fashion.
  • Another object of the present invention is to provide a system to close a door of a household appliance, which can enable a pre-opening of the door in an automatic and safe manner.
  • this opening can be used to establish a communication between the inner chamber and the outside, through the access opening.
  • the idea of enabling a pre-opening is particularly advantageous - by way of example, though not exclusively - in washing machines, such as dishwashers, since it allows the steam generated during the washing cycle to be let out, thus contributing to the at least partial drying of the articles contained in the washing chamber.
  • W indicates, as a whole, an example of a washing machine, on which a first and, respectively, a second explanatory embodiment of a system 10, 110 according to the present invention is suited to be installed.
  • the washing machine is a dishwasher W, though, as confirmed by the following description, system 10, 110 can also be applied to different washing machines or to other household appliances.
  • dishwasher W has a casing C, in which a washing tank or chamber WT is defined, for receiving the dishes to be washed.
  • Washing tank WT has an access opening O, through which the same communicates with the outside and which, therefore, is able to house the dishes.
  • dishwasher W has a door D, for opening and closing access opening O ( figure 1 ).
  • Access opening O is arranged on a front face of casing C and, preferably, door D is pivotable relative to casing C, for example it is hinged along a horizontal axis that is arranged in the lower part of the latter.
  • access opening O is peripherally provided with a sealing gasket SG, so as to allow washing tank WT to be closed in a fluid-tight manner, when door D is in a completely closed condition.
  • casing C has a lid L, which is advantageously arranged on the top of said casing C.
  • the system is designed to allow door D of dishwasher W to be closed and comprises an engagement element 11, for being fitted in correspondence to casing C, for example on the cross bar CB arranged between casing C and lid L.
  • Engagement element 11 is suited to be held in a releasable manner by a retaining element 16, for being fitted on door D, for example on its rear face facing access opening O.
  • Retaining element 16 is suited to hold engagement element 11 in a releasable manner, so as to constrain door D to casing C, when washing machine W is being used.
  • engagement element 11 is fitted on casing C and retaining element 16 is fitted on door D.
  • Engagement element 11 comprises a support element 12, which, in the embodiments shown, is fixed to casing C.
  • Engagement element 11 comprises, furthermore, a striker 14, for being coupled, in a releasable manner, to retaining element 16 and is movable, relative to support body 12, between a retracted position ( figures 4 and 5 ) and an extracted position ( figures 6 and 7 ).
  • support body 12 is manufactured as an internally hollow case, for example comprising a pair of half-shells or cups 12a, 12b, which are coupled to one another - in particular in an interlocking manner - in the area of their periphery.
  • half-shells 12a, 12b of support body 12 are manufactured with a plastic material, for example by means of injection molding.
  • support body 12 is screwed to casing C of household appliance W.
  • striker 14 is movable in such a way that it is guided by support body 12, in particular by inner walls thereof.
  • striker 14 can slide relative to support body 12.
  • striker 14 is manufactured with a plastic material, for example by means of injection molding.
  • striker 14 can translate between the retracted position and the extracted position.
  • striker 14 in the retracted position, striker 14 partially projects from support body 12 with a section, whereas, in the extracted position, striker 14 further projects with an additional section.
  • striker 14 projects through a slit (without reference number), which is obtained on the front face of casing C of dishwasher W, on which engagement element 11, as a whole, is mounted.
  • Retaining element 16 is substantially of a known type and has, for example, a containing body, which is provided with a slit and houses a coupling mechanism, which can be accessed by striker 14 through said slid, so as to allow the striker 14 itself to be coupled in a releasable manner to said coupling mechanism.
  • said coupling mechanism is pivotable between an operating position and a rest position and comprises a rotary member, whose movement is opposed by an elastic member and which is suited be engaged in a releasable manner by striker 14.
  • the rotary member of the coupling mechanism holds striker 14 when door D is closed.
  • the rotary member of the coupling mechanism releases striker 14 when the user operates a suitable release mechanism (not shown), for example including a push-button, a lever or a knob, which is arranged on door D.
  • a retaining element 16 of the type described above are widely known in the technical field and are described in detail in many prior art documents.
  • Italian patent applications no. TO97A1120 , TO2000A000383 and TO2001A01003 are mentioned, whose content is to be considered as included herein by mere way of example. Therefore, for sake of brevity, retaining element 16 will not be further disclosed in the description below.
  • striker 14 when striker 14 is coupled to retaining element 16 and moves to the extracted position, it allows retaining element 16 to be moved away from support body 12, which consequently causes door D to be moved away from casing C.
  • door D due to the coupling between striker 14 and retaining element 16, door D remains in any case constrained to casing C, though without closing access opening O in a fluid-tight manner.
  • engagement element 11 preferably comprises a stop assembly, which is indicated, as a whole, with number 18.
  • stop assembly 18 is fitted on support body 12; in particular, it is contained in the cavity defined the support body 12 itself.
  • Stop assembly 18 moves between:
  • engagement element 11 comprises moving means 20, in particular electrically operated ones, comprising a bidirectional motor 22 (for example, an AC one) and a transmission mechanism 24, which is operated by motor 22 and cooperating with striker 14.
  • motor 22 is designed to selectively deliver to transmission mechanism 24:
  • moving means 20 are configured to:
  • moving means 20 are connected to a control device 21, for controlling moving means 20 according to predetermined use conditions.
  • moving means 20 are mounted on support body 12, for example they are housed in the cavity defined therein.
  • motor 22 and transmission mechanism 24 are located in support body 12, in particular in lower half-shell 12b.
  • motor 22 controls the movement of striker 14 and of stop element 18 through transmission mechanism 24.
  • motor 22 is a bidirectional one, which means that it can selectively deliver, as an output, a torque oriented in a direction of rotation and also in the opposite direction of rotation.
  • transmission mechanism 24 comprises a gear 26 driven by motor 22 and cooperating with striker 14, in particular through a rack coupling (for example, by means of a linear toothing 27 carried by striker 14 and shown in figures 5 and 7 ).
  • gear 26 simultaneously cooperates with stop assembly 18 in the ways that are described more in detail below.
  • gear 26 comprises a plurality of toothed wheels 26a-d, which cooperate with one another and are supported in their rotation by support body 12, for example by pins (with no reference numbers) projecting from lower half-shell 12b.
  • stop assembly 18 comprises a cam 28, which can be moved to operate motor 22, and a cam follower 30, for cooperating with cam 28 in an elastically countered manner (for example countered by an elastic member, such as a spring 32).
  • cam follower 30 is adapted to be subjected to a stress through a push of cam 28; alternatively, cam follower 30 can be subjected to a stress through a pull of cam 28.
  • cam 28 can be adapted to stress cam follower 30 through push and pull, thus creating between the two of them a desmodromic cooperation or configuration.
  • stop assembly 18 comprises, furthermore, a lock bolt 34, which is movable relative to support body 12 under the control of cam follower 30, in particular relative to lower half-shell 12b, and is designed to:
  • the movement of cam 28 is controlled by moving means 20.
  • the movement of cam 28 takes place through transmission mechanism 24.
  • the rotation of cam 28 is controlled by gear 26, for example cam 28 being carried by one of toothed wheels 26a-d.
  • cam 28 is carried by the toothed wheel indicated with 26c.
  • cam follower 30 comprises a stem 30a, for cooperating with the profile of cam 28 (for example being pushed by the latter), and a head 30b, which is advantageously wider and is designed to cooperate, in turn, with lock bolt 34 (for example pushing the latter) so as to move stop assembly 18 to the locking condition and to the release condition.
  • lock bolt 34 is movable so as to be coupled to a recess 36 made in striker 14 when stop assembly 18 is in the locking condition. Accordingly, when stop assembly 18 is in the release condition, lock bolt 34 is uncoupled from recess 36.
  • lock bolt 34 is rotary relative to support body 12, in particular it being coupled to cam follower 30 with a clearance.
  • head 30b is coupled to lock bolt 34 with a clearance, so that the push of cam follower 30 causes an oscillation movement of lock bolt 34, in particular in such a way that it engages and disengages recess 36.
  • spring 32 is mounted so as to cooperate with cam follower 30 (for example pushing the latter), tending to hold it in the locking condition of stop assembly 18, i.e. in a coupling with striker 14, for example in recess 36.
  • the action of spring 32 is used to counter the push exerted by cam 28 upon the cam follower 34.
  • control device 21 comprises a sensor assembly, for detecting at least one between the position taken on by striker 14 and the condition assumed by stop assembly 18. More in particular, the sensor assembly is designed to detect at least one between:
  • the sensor assembly comprises at least one position sensor, for example a pair of limit stop switches 38a, 38b (such as micro-switches), and for detecting at least one between the position taken on by striker 14 and the condition assumed by stop assembly 18.
  • each limit stop switch 38a, 38b detects a respective parameter between the position taken on by striker 14 and the condition assumed by stop assembly 18.
  • control device 21 further comprises a control unit 40, for example obtained on a printed circuit board.
  • control unit 40 is adapted to control motor 22 based on the detections of the sensor assembly (in particular, of limit stop switches 38a, 38b), so as to allow striker 14 to move between the retracted position and the extracted position according to some predetermined criteria.
  • the sensor assembly in particular, of limit stop switches 38a, 38b
  • device 21 can be programmed in such a way that the limit stop switches 38a, 38b provide detections that cause control unit 40 to have motor 22 reach its maximum torque and invert its direction of rotation. In this way, striker 14 returns to the retracted position, thus preventing moving means 20 - in particular transmission mechanism 24 - from being subjected to abnormal mechanical stresses.
  • moving means 20 are adapted to create an intermittent rotation motion to move striker 14 between the retracted position and the extracted position.
  • striker 14 remains still in its position (in particular, in the retracted position) when stop mechanism 18 moves between the release condition and the locking condition.
  • transmission mechanism 24 has a main toothed wheel 26c, which has an interruption 42 in its outer toothing, so that said main toothed wheel 26c is not capable of meshing with the following toothed wheel 26d.
  • main toothed wheel 26c is not capable of provoking the rotation of the toothing of following toothed wheel 26d and, therefore, striker 14 is not caused to move between the retracted position and the extracted position (thus remaining still in its position).
  • transmission mechanism 24 operates like a Geneva stop wheel or, more in general, similarly to further kinematic mechanisms that can provide an intermittent rotation motion for the control of the movement of striker 14.
  • engagement element 11 shows some components of engagement element 11, such as striker 14, stop assembly 18 and transmission mechanism 24. These components are shown in a plan view from below ( figures 4 and 6 ) and, respectively, in a plan view from above ( figures 5 and 7 ) for an observer watching engagement element 11 shown in figure 2 .
  • striker 14 is shown in the retracted position and stop assembly 18 is in the locking condition. In this configuration, in use, it is desired to do is to release striker 14 from the connection with stop assembly 18, in order to then move striker 14 from the retracted position to the extracted position in a following step.
  • control device 21 causes a rotation of gear 26, so that main toothed wheel 26c is driven in a rotation R1 in a clockwise direction for those observing figure 4 .
  • cam 28 which rotates together with main toothed wheel 26c, has its increasing bending radius and cooperates with cam follower 30 (for example pushing it in the direction of arrow F1).
  • lock bolt 34 is oscillated in such a way that it gets uncoupled from recess 36 carried by striker 14, thus causing stop assembly 18 to assume the release condition.
  • main toothed wheel 26c has its interruption 42 facing the toothing or pinion of the following toothed wheel 26d. Therefore, in this step, main toothed wheel 26c is not capable of transmitting any rotation to following toothed wheel 26d. Hence, gear 26 cannot control the movement of striker 14 from its retracted position, where the latter remains still.
  • striker 14 is shown in the extracted position and stop assembly 18 is in the release condition. In the configuration shown therein, the movement of striker 14 from the retracted position to the extracted position has already occurred.
  • control device 21 causes a further rotation of gear 24, so that the main toothed wheel 26c is driven in a further rotation R2 in a clockwise direction for those observing figure 6 .
  • cam 28 which rotates together with main toothed wheel 26c, has its constant bending radius and keeps cam follower 30 still in its position. In this way, lock bolt 34 remains uncoupled from recess 36 carried by striker 14, in the release condition of stop assembly 18.
  • main toothed wheel 26c has its toothing facing and meshing with the toothing or pinion of the following toothed wheel 26d. Therefore, in this step, main toothed wheel 26c is capable of transmitting a rotation to the following toothed wheel 26d.
  • gear 26 controls the movement, in the direction of arrow F2, of striker 14 from its retracted position to its extracted position, thus bringing it to the arrangement shown in figures 6 and 7 .
  • stop assembly 18 is in the release condition, whereas striker 14 is in the extracted position.
  • limit stop switches 38a, 38b are adapted to detect the condition of stop assembly 18 and position of the striker 14, so that the rotation of motor 20 is inverted by control device 21 in case striker 14 needs to be moved back to the retracted position.
  • the operating steps described herein must be carried out in reverse order and with opposite directions of movement compared to the ones described above.
  • Figures 8 to 13 show a system 110, manufactured according to a second embodiment of the present invention.
  • Said system 110 is substantially similar to system 10 manufactured according to the first embodiment of the present invention. Therefore, details and elements that are similar to those of the embodiment described above or fulfill a similar function are associated with the same alphanumeric references. For the sake of brevity, the description of these details and elements will not be repeated below, but reference is made to what was previously explained in the description of the first embodiment.
  • the second embodiment of system 110 differs from the first embodiment of system 10 because stop assembly 18 is not provided.
  • This solution ensures a quicker opening and closing operation compared to the first embodiment of system 10.
  • motor 22 (for example a CC motor) is coupled to transmission mechanism 124 through a worm screw (with no reference number).
  • transmission mechanism 124 being provided with a safety clutch 142, which is capable of uncoupling it from motor 22 in case there are abnormal torques running through gear 26.
  • transmission mechanism 124 comprises a main toothed wheel 124b, on which there is mounted safety clutch 142, which disconnects said main toothed wheel 126b from the following toothed wheel 126c (which, in turn, meshes with a linear toothing shown by striker 14, thus creating a rack coupling).
  • Safety clutch 142 can be designed, by mere way of example, with an unadjustable disengagement torque ( figures 10-13 ) or with an adjustable disengagement torque ( figures 14-18 ) .
  • the safety clutch comprises a meshing system for at least one pin 144 with at least one respective striker spring 146, for cooperating with the pin 144, engaging it, thus causing main toothed wheel 126b to be constrained, in its rotation, to the following toothed wheel 126c.
  • a pair of pins 144 and a respective pair of striker springs 146 are provided.
  • pins 144 When the torque transmitted through the safety clutch 142 exceeds a predetermined threshold value, pins 144 are subjected to a stress that is such as to overcome the action of the respective striker springs 146, thus disconnecting the main toothed wheel 126b from the following toothed wheel 126c. In this way, the kinematic connection between the main toothed wheel 126b and the following toothed wheel 126c becomes "idle", thus making them independent in their rotation for transmitted torques that are too high.
  • the safety clutch comprises a plate 244 cooperating with a spring 246, which, in turn, is pre-loaded (for example through compression) and can be moved relative to plate 244 by a dowel 248, thus constraining, in their rotation, main toothed wheel 126b and the following toothed wheel 126c.
  • safety clutch 142, 242 ensures a safe operation of engagement element 11, since the generation of excessively high torques typically corresponds to an operating fault of the system, which can jeopardize the operation thereof. Therefore, safety clutch 142, 242 makes sure that there is a proper disengagement when torque predefined values are reached or exceeded, which are predetermined based on designing and building needs.
  • the transmission mechanism indicated with 24 can integrate a safety clutch so as to fulfill the functions described above, which, for the sake of brevity, will not be further discussed herein.
  • said safety clutch can be the one indicated with 142 in figures 10-13 or the one indicated with 242 in figures 14-18 .
