Definitions

  • the present invention relates to a door locking device for household appliances and a bistable mechanism for latching a cursor.
  • Certain household appliances have doors that allow access to an inner cavity in which the appliance's typical functions are normally carried out.
  • Some examples of such household appliances are washing machines, dishwashers and the like.
  • One of these types includes those devices wherein, as the door of the appliance approaches its closed position, a hook is moved to the locking position through a lever actuated by the door itself.
  • US5072974 discloses a door locking device for a household appliance, adapted to engage into the closed position a door of an operational cavity of said household appliance, comprising:
  • this device comprises elastic recovery means between the hook and a connecting lever so as to allow a relative elastic movement between the hook and the lever.
  • the actuation lever when moved by the door, actuates an electric motor, which in turn moves the hook into the closed condition.
  • both the door-driven actuation lever and the hook are associated with inclined planes arranged on the hook end opposite to the one that must engage the door and on a slide connected to the actuation lever.
  • a first problem relates to the fact that it cannot compensate for any extra door travels and/or door position tolerances, with the risk that the door might be locked improperly or not at all.
  • This situation has a minimal impact when there is no actuation lever or when the latter acts as a switch push-button to control an electric motor.
  • Another drawback of this solution relates to the very accurate machining required by the inclined surfaces to ensure the correct hook movement, which affects production costs.
  • a further drawback relates to wear; in fact, after a certain number of operating cycles the inclined surfaces may wear out, resulting in substantially worse operating conditions and exposing the device to the risk of seizure.
  • the object of the present invention is to provide a door locking device for household appliances which can overcome these and other drawbacks.
  • the present invention thereby provides a door locking device for a household appliance, adapted to engage into the closed position a door of an operational cavity of said household appliance, comprising:
  • the cursor comprises at least one body provided with a seat that houses rotation and/or engagement guides; said bistable latching means comprise an engagement pin with a profiled head, preferably at least partly housed or delimited by said seat and rotatable relative to said cursor, which cooperates with said rotation and/or engagement guides to ensure that said cursor takes said at least two distinct positions of stable equilibrium, preferably as a result of a linear movement thereof.
  • the hook can be locked into a condition in which it engages the door through a slide which is separate from said lever, so that a movement of the latter deriving from an extra travel of the door will not impair the proper locking of the hook.
  • the invention further comprises a bistable mechanism according to claim 11 which can be used in the door locking device and/or in actuation means or in other applications.
  • bistable mechanism for latching a cursor, adapted to allow the cursor to take at least two distinct positions of stable equilibrium as a result of the repetition of an actuation force, comprising bistable latching means, wherein said cursor comprises at least one body cooperating with the bistable latching means to ensure that said cursor takes said at least two distinct positions of stable equilibrium as a result of a movement thereof, whereby said cursor comprises at least one head distinct from said body and coupled thereto through elastic recovery means so arranged as to allow a relative elastic movement between the head and the body, wherein the bistable latching means further comprises a pin which comprises a profiled head cooperating with rotation and/or engagement guides accommodated at least partly within the body of said cursor.
  • reference numeral 1 designates a door locking device according to a first embodiment of the present invention, as a whole.
  • the device of the present invention can be used as a door lock for a household appliance, since it is adapted to lock into the closed position a door of an operational cavity of the appliance.
  • the device comprises:
  • the hook actuation means 4 are adapted to control the movement of the hook 5 into the door engaging condition; to this end, they can be moved by the door between at least a first position, in which the hook 5 is not in a condition of engagement with the door, and a second position, in which the hook 5 is in a condition of engagement with the door.
  • the device 1 comprises a compensation means 8 adapted to compensate for a movement of the actuation means 4, in order to prevent or compensate for the actuation of said hook 5 in the presence of an additional movement of said hook actuation means 4, said "additional" movement being different from the movement between the first position and the second position.
  • any anomalous movements of the door or extra travels of the hook actuation means 4 can be compensated for, in the sense that they will not cause a movement or displacement of the hook which might compromise its engagement with the door or adversely affect the locking thereof, which takes place in said second position through the effect of the locking means, and/or cause damage.
  • any extra travels of the actuation means 4 substantially coincide with additional movements of said hook actuation means 4 past the second position, in the direction of movement from the first position to the second position.
  • the hook actuation means comprise at least one lever 4 which is linearly movable between said two positions and which is coupled to the hook 5 through said compensation means 8, so that the hook 5 is indirectly actuated by the lever through the interposition of said compensation means 8, preferably mechanically, thus advantageously simplifying the design of the device 1 and making it more effective.
  • the compensation means 8 is interposed between the lever 4 and the hook 5, and is coupled to both of them.
  • the compensation means 8 is an elastic means, and preferably comprises a coil spring 8 interposed between the hook 5 and the lever 4 to rotatably drag the hook 5 as a result of a linear movement of the lever 4 between said two (first and second) positions.
  • the coil spring compresses or extends in the presence of a movement of said lever other than that between said first position and said second position, thereby preventing said movements from improperly actuating the hook 5.
  • Said movements of the lever other than that between said first position and said second position may be generated, for example, by small tolerances of the door or by an extra travel of the lever.
  • the compensation means 8 may also comprise toothed wheels and/or cam profiles and/or a plastic elastomer or the like.
  • the device 1 further comprises locking means 6 adapted to lock the hook in the engaged condition.
  • said locking means 6 are separated from the actuation means 4 of the hook 5 for reasons that will be described later on.
  • the locking means 6 are adapted to lock the hook into the engaged position, taking a position in which they interfere with the hook itself, thus preventing it from moving.
  • Said locking means 6 comprise additional recovery means 63; in particular, these are used to prevent anomalous operation and/or actuation conditions.
  • Said recovery means 63 are elastic, e.g. springs, elastomers or the like.
  • the locking means 6 comprise a cursor 60 which is movable into a condition wherein it interferes with the hook 5, so as to lock it into a condition of engagement with said door.
  • the head 61 of the cursor 60 prevents the hook 5 from disengaging from the door, as will be described more in detail below.
  • the locking means 6 can be moved into a condition wherein they interfere with said hook 5 in a manner substantially independent of the position of the lever 4, in particular even in the presence of an additional movement of the latter other than the movement between said first position and said second position.
  • the device 1 comprises two half-shells 2 and 3 which can be coupled together to house the functional components of the device 1.
  • the two half-shells 2 and 3 are preferably made of plastic, e.g. by moulding, and are fitted with coupling and/or hooking means, such as elastic tabs and/or hooks, so that they can be coupled by snapping them together.
  • This description will first illustrate the components of the device 1 with reference to their function of engaging with a door of a household appliance, and then it will describe those components which are adapted to perform the locking operation in the engaged condition and the subsequent unlocking operation.
  • the device 1 comprises: the actuation lever 4, the hook 5, the locking means 6 and an actuator 7 for said locking means 6.
  • the latter may be of various types, but preferably it is of the type that comprises an electromagnet; it may however comprise a wax-type thermoactuator or a motor.
  • the actuator 7 is an electromagnet of a per se known type, fitted with a coil, a magnetic yoke 72 and a mobile core 73; the operation and any variants of this type of electromagnet are well known to those skilled in the art: in short, when power is supplied to it, the mobile core or piston is extracted, thus pushing the locking means 6 towards the hook 5.
  • the actuator 7 comprises an electromagnetic winding 75 associated with the respective magnetic yoke 72, through which the mobile stem or core 73 can pass and act upon the locking means 6;
  • the magnetic yoke 72 substantially has a "C" shape, and from its open side an electric connector 74 protrudes which is in particular intended for electrically connecting the actuator 7 to the control system of the household appliance in which the door locking device 1 has been incorporated or installed.
  • said yoke 72 also determines fixing or positioning means in a respective seat of the door locking device 1.
  • the connector 74 is preferably of the RAST type, such as Rast 2.5, and comprises coupling means for an external electric connector and/or coding means (not shown) adapted to define a connection with one external connector only, thus avoiding the risk of a wrong connection and/or positioning of the connector, e.g. reversed.
  • the actuator may be of a type other than electromagnetic, e.g. thermal or thermoelectric; in particular, said thermal or thermoelectric actuator is of a type that comprises at least one thermal actuator element, i.e. an element adapted to deform or expand or shrink depending on its temperature, and preferably also comprising an electric heating element, such as a resistor.
  • thermal actuator element i.e. an element adapted to deform or expand or shrink depending on its temperature
  • electric heating element such as a resistor
  • the body of the actuator may still have a control connector, whether of the RAST type or of a different kind.
  • Said thermal actuator (or thermoactuator or thermoelectric actuator) preferably comprises an expandable material, such as wax or the like, which expands when heated, thus promoting the displacement of a control element, e.g. the axial movement of a stem or piston, which can take at least two positions: an extracted position and a retracted position with respect to the actuator.
  • a control element e.g. the axial movement of a stem or piston
  • thermoactuator is fitted with electric connectors that, as aforementioned, may be of the RAST type or of a different kind.
  • thermoactuator that may be used in this case is described in European patent applications EP 781 920 and EP 953 198 by the present Applicant.
  • thermoactuator might comprise a form memory element, in particular of the type adapted to expand or shrink as temperature increases, such as a metal alloy or a thermoplastic or polymeric material.
  • the compensation means 8 adapted to compensate for any extra travel of the lever 4, which in this example comprises at least the coil spring 8, coupled to the hook 5 and to the lever 4.
  • the lever 4 is made in one piece with (or is likewise coupled to) a slide 9 which can slide within the device 1.
  • the hook 5 is rotatable about a fulcrum 10 arranged substantially perpendicular to the sliding direction of the slide 9, and shown in detail in Figs. 6 to 11 .
  • the device 1 is mounted on the frame or chassis of the household appliance, in a manner such that the lever 4 comes in contact with a door of the appliance when the door is rotated or moved to close an operational cavity of the appliance itself.
  • the door of the household appliance is provided with a seat into which the hook 5 can be engaged.
  • the door actuates the lever 4, which slides within the device thanks to the slide 9, and in its turn actuates the spring 8, which then rotates the hook 5, which thus engages into the seat provided on the door.
  • one end of the spring 8 may grip the slide 9 instead of the lever 4, without however altering the operation and the principle of operation described.
  • the spring 8 acts as a means for compensating any anomalous movements of the lever 4, e.g. an extra travel thereof: in fact, if the travel of the door is such as to displace the lever 4 past the point where the hook 5 is engaged with the door, this additional movement (extra travel) will cause no further movements of or damage to the hook because the spring 8 will compress and will allow the lever 4 to move beyond said position without the hook being rotated any further.
  • this overcomes the drawbacks of prior-art solutions, since the presence of the compensation means 8, in this case the spring, ensures the correct positioning of the device even in a condition of improper installation or excessive operation or production tolerances.
  • the hook is in a condition of non-engagement with the door: in fact, it is rotated in such a way that its front end 5a is raised.
  • the compensation means equivalently comprise, as a replacement for the spring 8, a different elastic means, e.g. capable of operating in a different way or at different points between the lever 4 and the hook 5, or capable or absorbing said extra travels of the actuation means 4, such as a rubber rod or the like, so long as it is adapted to deform elastically to compensate for said extra travels.
  • the slide 9 is associated with an additional spring 14 gripping the slide 9 and the lower shell 3, so that the slide 9 (and hence the lever 4) are subject to an elastic reaction and are therefore pushed in the direction opposite to the sliding direction of the slide 9 during the engagement manoeuvre (when the door abuts on the lever 4).
  • the spring 14 thus performs the task of allowing the lever 4 to be moved or reset to the disengaged position of the hook 5 when the door is opened.
  • the slide 9 also comprises a longitudinal extension 15, which in this example is the free end of the slide 9 opposite to the end coupled to the lever 4.
  • the longitudinal extension 15 is useful to control signalling and/or control means 16, such as an electric switch 16, which is also housed in the shell 3, e.g. a push-button switch, so that when the door is closed the push-button activates an electric or electronic signalling and/or control circuit, e.g. to turn on a warning light on the front panel of the household appliance and/or to enable the operation of the latter and/or to enable the power supply to the actuator 7 in order to lock the condition of engagement, as will be described more in detail later on.
  • an electric switch 16 which is also housed in the shell 3, e.g. a push-button switch, so that when the door is closed the push-button activates an electric or electronic signalling and/or control circuit, e.g. to turn on a warning light on the front panel of the household appliance and/or to enable the operation of the latter and/or to enable the power supply to the actuator 7 in order to lock the condition of engagement, as will be described more in detail later on.
  • the device 1 includes for this purpose locking means 6 which in this example comprise the cursor 60 fitted with at least the head 61, which is movable by the actuator 7 into a condition where it interferes with the hook 5 when the latter is in a condition of engagement with the door.
  • locking means 6 which in this example comprise the cursor 60 fitted with at least the head 61, which is movable by the actuator 7 into a condition where it interferes with the hook 5 when the latter is in a condition of engagement with the door.
  • the hook 5 has a free rear end 5b on the side of the fulcrum 10 opposite to the front end 5a, so that when the latter rises relative to the lower shell 3 the former will descend, and vice versa.
  • the head 61 of the cursor 60 has approached the rear end 5b of the hook without however interfering therewith, and in this position the hook 5 is raised.
  • the device arrives at the condition shown in Fig. 15 , wherein the actuator 7 has moved the cursor 60 due to the presence of bistable latching means 65, which will be described later on.
  • bistable latching means 65 As for said bistable latching means 65, they are shown in different operating positions in the detail illustrated in Figs. 22 and 23 and in Figs. 24 to 28 .
  • the cursor 60 comprises, in addition to the above-described head 61, also a body 62 elastically connected to the head 61 through the interposition of the springs 63 for reasons that will be discussed hereafter.
  • the end of the body 62 opposite to that connected to the head 61 has an abutment profile 64 for the piston of the actuator 7.
  • the cursor 60 also comprises bistable latching means 65 adapted to allow said cursor 60 to take at least two distinct positions of stable equilibrium as a result of the repetition of the same force of actuation deriving from the action of the actuator 7.
  • Said bistable latching means 65 comprise an engagement pin 66 with a suitably profiled head, e.g. a substantially butterfly-like head 66A associated with a cylindrical body 66B, as shown also in the exploded view of Fig. 12 .
  • the free end of the body 66B of the engagement pin 66 is engaged into a respective circular seat of the housing 3; said profiled head 66A is free to rotate by moving within a seat 67 of the body 62.
  • the seat 67 is internal to the body 62 and is closed at the sides, as shown in Fig. 29 , as well as at its top and bottom faces by the half-shells 2 and 3; this configuration allows protecting the components of the bistable mechanism 65 housed therein.
  • the seat 67 may however be open, at least partially along at least one side, while still remaining substantially internal to the body 62.
  • the seat 67 accommodates, at least partly, rotation and/or engagement guides 68,69 cooperating with said butterfly-head pin 66.
  • the head 66A of the engagement pin 66 is made in one piece with the body 66B, which is free to rotate about its axis.
  • the head 66A of the engagement pin 66 is housed in the seat 67; when in operation, it comes in contact with the rotation and/or engagement guides 68,69 with which it cooperates: in fact, during the sliding action of the cursor 6, generated by the actuator 7, the seat 67 moves integrally with the body 62 with respect to the pin 66.
  • the preferred version of the head 66A of the pin 66 comprises two opposed ends projecting out of the area of engagement with the pin body 66B and provided with two notches or seats, e.g. two V-shaped notches.
  • the rotation guides 68,69 comprise coupling portions to be coupled to said notches of the pin 66, which are adapted to allow for mutual engagement between the parts in order to cause a rotation or stop the rotation of the pin 66, as will be described more in detail hereafter.
  • At least one of the engagement means 66 and the rotation and/or engagement guides 68,69 is at least partly located in a position substantially internal to the seat 67.
  • the body 62 also comprises a seat 70 adapted to house the return spring 71 acting between the body 62 itself and the underlying shell 3; the return spring 71 is so fitted as to keep the body 62 pushed in the direction of the profile 64, i.e. towards the actuator 7. In this manner, the body 62 can be subject to two distinct forces: the force of the return spring 71 and the force of the actuator 7, which act in opposite directions; in particular, the actuator 7 counters the force of the return spring 71.
  • Figs. 24 to 28 provide a better view and understanding of the operation of the bistable latching means 65.
  • Fig. 24 The position of Fig. 24 is considered to be stable because the cursor 60 is subject to the opposed forces of the actuator 7 and of the return spring 71.
  • the head of the pin 66 would abut against the front wall (the upper one in the drawing) of the seat 67, thus advantageously remaining stably in this condition even when the actuator 7 is off.
  • the cursor 60 then goes through the position of Fig. 25 , which is not stable (i.e. it cannot be held without keeping the actuator piston extracted, and therefore without keeping the actuator on).
  • the head of the pin 66 comes in contact with the rotation guide 69, which engages into the pin 66 and causes it to rotate by a certain predetermined number of degrees.
  • the head 66A of the pin 66 has two opposite ends 66C and 66D arranged substantially at 180° and each having a concave seat or notch, e.g. a V-shaped notch, 66E and 66F.
  • Each rotation and engagement guide 68, 69 comprises an engagement relief or angle 68A,69A to be engaged with the concave notch 66E and 66F, and a guide portion 68B,69B so oriented as to generate or induce a rotation of the pin 66 when the concave notch 66E,66F engages with the engagement angle 68A,69A, thus causing a rotation of the pin 66 itself.
  • the head 61 is advanced towards the hook 5; in particular, it is positioned under the rear end 5b of the hook 5, thereby locking the engagement between the latter and the door, even when the actuator 7 is off: in fact, the hook cannot rotate into the condition of disengagement of the door.
  • This backward movement removes the head 61 of the cursor 60 from under the rear end 5b of the hook 5, thereby unlocking the engagement between the latter and the door.
  • the device 1 can thus advantageously lock the engagement between the hook 5 and the door of the household appliance without keeping the actuator 7 on.
  • the head 61 is connected to the body 62 through the interposition of the springs 63.
  • the latter can prevent problems from arising when the device 1 is in operation.
  • the spring 63 are so arranged as to allow a relative elastic movement between the head 61 and the body 62: let us assume that, in operation, the hook 5 is engaged and seized (for whatever reason) with its end 5b pressing against the head 61 of the cursor 60; in this condition, if the head 61 were rigidly connected to the body 62, an activation of the actuator might easily break one or more of the various parts or anyway it might not allow unlocking because the cursor 60 would not be able to move.
  • the head 61 of the cursor 60 is elastically connected to the body 62, in the event of such a seizure the body 62 will be able to move, thus allowing the pin 66 to rotate.
  • At least the step described with reference to Fig. 27 can also take place with the end 61 blocked by the hook 5, e.g. in the event of an intervention of the actuator 7 while the user is pulling the door, in which case the hook 5 would be stressed in a manner such that its portion 5B would push excessively against the portion 61 of the locking means 6; in such a case, the locking means 6 can nevertheless disengage from the pin 66, to move then backwards as soon as said anomalous force against the door, and hence against the hook, ceases.
  • the presence of the elastic connection between the head 61 of the cursor 60 and its body 62 also provides a further advantage: in fact, in the event of an anomalous seizure of the head 61 under the hook 5, as previously described, the head 61 can be moved manually from under the hook 5 without having to move the body 62 as well, thus avoiding any damage to the device 1.
  • the springs 63, 71, 8 may be replaced with alternative elastic means, e.g. elastic means made of elastomer or thermoplastic material, provided that they can perform the above-described functions.
  • FIG. 19 An alternative embodiment of the compensation means 8 for a device 11 similar to the device 1 is shown in Figs. 19 to 21 .
  • This variant 11 differs in that the compensation means does not comprise the spring 8 of the previous example; in its place, the lever 40 is fitted with a side extension 41 having at least one face 40A which is inclined with respect to the sliding direction of the slide 90, which is integral with the lever 40 itself as shown in Fig. 20 .
  • the hook 50 comprises an outer surface with segments 50A, 50B, 50C, 50D progressively inclined or curved with respect to the side extension 41, thus generating a series of contiguous inclined planes or a single curved plane; the hook 50 further comprises a flat top portion 50E, visible in Fig. 20 , which is straight and parallel to the sliding direction of the lever 40.
  • Said segments 50A, 50B, 50C, 50D cooperate with the inclined face 40A to rotate the hook 50 when the lever 40 goes back as a result of the door closing movement.
  • the lever 40 can be further moved in the direction opposite to that of the door (e.g. because of an anomalous movement of the latter) without such movement causing a wrong displacement of the hook or generating excessive forces or malfunctions when locking the hook 50 into the engaged condition: it should be noted, in fact, that the hook 50 is moved through the effect of the cooperation between said segments 50A, 50B, 50C, 50D and the inclined face 40A of the lever, and that the latter is free to slide over the flat top portion 50E of the hook 50, thus not moving or stressing the latter any further.
  • step of locking the hook 50 into the engaged condition is carried out in the same way as previously described, i.e. by using the cursor 60 to engage and rotate the hook 50 like a latch, and therefore it will not be discussed any further.
  • the side extension 41 is at least partly made of an elastic material (e.g. elastomer or rubber), thus summing together the above-mentioned advantages.
  • an elastic material e.g. elastomer or rubber
  • the side extension or at least a portion of the lever, is fitted with a tolerance compensation device which, in addition to acting upon cooperating inclined planes of the hook and of the lever, also comprises an elastic insert which absorbs any tolerances or extra travels.
  • cursor 60 can be directly connected to or associated with the hook 5, preferably in order to move it into the lockable condition of engagement with the door upon activation of the actuator that cooperates with the cursor.
  • the actuator 7 is turned on when one wants to close or lock the door, so that the cursor 60 moves and interferes with the hook 5 to move it into the condition in which it closes and/or locks the door.
  • the bistable latching means 65 may be subject to variations as well; for example, the rotation guides 68 and/or the engagement means 69, which in the embodiment shown in the drawings are associated with the body 62 of the cursor 60, may instead be at least partly associated with the lower half-shell 3 of the device.
  • trajectory of the cursor may also be curvilinear; for example, the body 62 may be guided by a cam profile arranged on the side of the lower half-shell 3.
  • the device according to the invention may also include an actuator 7 exerting a pulling force onto the cursor 60, instead of pushing it as in the previous example.
  • Such a solution may be implemented by appropriately modifying the actuation and/or locking means 6 of the hook 5, e.g. by changing the configuration of the cursor 60 in a manner such that, when it is retracted towards the actuator 7, the spring 71 therewithin is compressed; for example, the cursor 60 may be similar to the one shown in the various examples described above, but substantially rotated by 180° relative to the axis of the engagement pin 66.
  • the head 61 of the cursor will still be placed on the end of the cursor 60 facing the hook 5; for this reason, the shape of the cursor will be slightly different from the one shown in the drawings.
  • the actuator 7 moves and holds at least temporarily the cursor 60 while countering the force of the spring 71, which operates in the way opposite to the previous example; the cursor 60 is then held by the bistable latching means 65.
  • the latter allow locking the cursor 60 in a position away from the hook 5, following a first operating step of the actuator 7 in which it pulls the cursor towards itself by overcoming the elastic countering force of the spring 71.
  • the actuator 7 pulls the cursor 60 towards itself again to disengage the bistable latching means 65 and allow it to move under the thrust of the spring 71.
  • the cursor 60 can be disengaged by the actuator and can snap forwards, with the aid of the spring 71, to lock it, just as in the example taken into account in the drawings.
  • the mobile core 73 of the actuator is connected to the cursor 60 (e.g. by means of a hook-hole solution or the like), so that it can exert onto it the force required to retract it towards the actuator 7, in contrast with the force of the spring 71.
  • bistable catching mechanism comprising at least the cursor 60, with the pin 66, the head 66A, the guides 68 and the engagement means 69, can also be used in other devices where bistable mechanisms are required.
  • Such devices are not necessarily door locking devices like the one taken into account herein; for example, they may be devices for stopping mobile components of household appliances such as washing machines, dishwashers or the like.
  • bistable mechanism may also be associated with an actuator, e.g. of the previously described electromagnetic or thermoelectric type, in order to obtain a bistable actuator, such as an electric actuator adapted to take two stable working positions.
  • an actuator e.g. of the previously described electromagnetic or thermoelectric type
