Definitions

  • the present invention relates to a door-locking device for an electrical household appliance, in particular an oven, having the characteristics referred to in the preamble of Claim 1.
  • Devices of this type are known, for example, from EP 1640493 A2 and EP 1703212 A2 , filed in the name of the present Applicant, and DE 102004061231 B3 .
  • devices of the type referred to usually comprise a main body, associated to which are a movable locking member and a corresponding actuation system, which can be electrically controlled for displacing the locking member between an operative condition or condition of engagement and an inoperative condition or condition of release, with respect to a suitable retention element.
  • the main body of the door-locking device is usually fixed to the stationary structure of the appliance, with its locking member that is able to co-operate with the retention element, which is defined or mounted on the door of the appliance.
  • the main body of the device is, instead, fixed to the door, and the retention element is associated to the stationary structure.
  • some door-locking devices - such as the ones described in the aforesaid prior documents - are provided with a release arrangement, which may be actuated manually to bring about passage of the locking member from its condition of engagement to its condition of release so as to enable in any case opening of the door.
  • This arrangement is basically conceived so as to enable a translation on the main body of the device of a rotation pin of the locking member, with respect to a working position thereof, so that the locking member can be released from the retention element.
  • the aforesaid translation may be obtained by forcing opening of the door, i.e., applying to the door an opening force that is significantly greater than the minimum force necessary for opening the door itself, when it is not locked via the door-locking device.
  • the system for locking the door presupposes the co-operation of components that are associated to two different parts of the appliance, one of which (the door) is mounted movable with respect to the other (the stationary structure).
  • the locking member and the corresponding retention element must hence be able to interact in a precise way, i.e., in accordance with the design specifications. This imposes a particular attention and precision in installation of the components in question on the respective parts of the appliance, as well as of the aforesaid parts with one another (the door with respect to the stationary structure).
  • the relative position between the locking member of the device and the corresponding retention element is not optimal, or in any case is not such as to guarantee proper and safe operation of the device over time.
  • some door-locking devices are provided with a compensation arrangement, aimed at enabling the locking member to adapt its own working position as a function of the relative positions of assembly or installation between the parts involved (the main body of the device, the stationary structure of the appliance, the door and the retention element), in the case where these positions differ from the ones predefined in the design stage.
  • the compensation arrangement is provided by the same release arrangement mentioned previously (or vice versa), and for this purpose comprises elastic means that constantly urge the rotation pin of the locking member downwards, into its working position on the main body, enabling a displacement of the pin for the purposes of compensation.
  • the aforesaid elastic means also enable autonomous recovery of the working position of the pin of the locking member, after this has been induced to displace upwards following upon a compensation of the mechanical tolerances and/or a forced opening of the door.
  • the device of DE 102004061231 B3 has an articulation arrangement for the locking member which is able to perform angular displacements relative to the stationary structure or the door.
  • the present invention has the aim to provide a door-locking device for an electrical household appliance, provided with a release arrangement and/or a compensation arrangement, production of which is further simplified and reliability of which is increased.
  • references to "an embodiment”, “one embodiment”, “various embodiments”, and the like, in the framework of the present description is intended to indicate that at least one particular configuration, structure, or characteristic described in relation to the embodiment or embodiments is comprised in at least one embodiment.
  • phrases such as “in an embodiment”, “in one embodiment”, “in various embodiments”, and the like that may be present in various points of this description do not necessarily refer to one and the same embodiment, but may instead refer to different embodiments.
  • particular conformations, structures, or characteristics defined in the framework of the present description may be combined in any adequate way in one or more embodiments, which may even be different from the ones represented.
  • a door-locking device provided for use on an electrical household appliance equipped with a door or hatch.
  • the electrical household appliance is a cooking oven and that the device 1 is provided for locking the hatch or door of the oven in the respective closing condition, when an operating program is in progress, for example a program of pyrolytic self-cleaning.
  • the device 1 comprises a supporting body 2, which is to be secured to the stationary structure 100 of the oven, such as its cabinet or load-bearing frame, on a respective resting surface.
  • the stationary structure 100 is illustrated limitedly to a portion of a wall thereof, for example a horizontal wall, on which the body 2 is secured. Consequently, in the examples provided, the aforesaid resting surface - designated by P for example in Figures 12-14 and 16 - is defined by the aforesaid, preferably horizontal, wall, the surface being substantially parallel to the wall.
  • the body 2 which is preferably generally box-shaped, may be made of a single piece, for example a moulded plastic material, but not excluded from the scope of the invention is an embodiment thereof in a number of parts rendered fixed with respect to one another, possibly also via an articulated or at least in part movable coupling, for example in such a way that two parts of the body 2 will be movale with respect to one another.
  • the body 2 comprises two side walls 2a, a rear wall 2b, and a lower or bottom wall 2c, which in the example is resting on the structure or wall 100.
  • the body 2 supports in a displaceable way a locking member, which is designed to co-operate with at least one retention element associated to the door of the oven, or defined therein.
  • the locking member designated by 3
  • the member 3 is preferably basically shaped like a hook; in the sequel of the present description, the member 3 will thus be identified as "hook", for simplicity.
  • the hook 3 is hinged or pivoted to the body 2 via respective constraint means, preferably comprising a pin 4, which extends between two generally parallel portions of the side walls 2a, in a front area of the body 2, these wall portions being purposely provided with coaxial holes for the pin 4.
  • the hook 3 is in this way able to turn or move angularly about an axis identified by the pin 4, this axis being designated by X 1 , for example in Figure 3 .
  • the pin 4, which is preferably cylindrical and made of metal material, may be a component distinct from the body of the hook 3 and be inserted in a transverse through hole of the hook itself.
  • the pin 4 may be made up of two reliefs or appendages projecting from opposite sides of the hook 3, which are coaxial, or else the pin 4 may be made up of two reliefs or appendages projecting from the facing sides of the side walls 2a of the supporting body 2, which fit into corresponding lateral holes or seats in the hook 3.
  • the device 1 has an actuation system, which comprises an electric actuator 5 controllable for causing displacements of the hook 3.
  • the actuator 5, preferably fixed on the body 2 consists of a rotary motor, provided with electrical terminals, designated by 5a only in Figure 1 , for its electrical supply.
  • the actuator 5 could, however, be of some other type, such as a linear actuator, for example an electromagnet or an actuator of a thermal or electrothermal type.
  • the actuation system of the device 1 further comprises a transmission arrangement, designated as a whole by 6 for example in Figure 3 , configured for transferring to the hook 3 an actuation imparted via the actuator 5.
  • the transmission arrangement 6, which is mounted on the supporting body 2, may be of any known type and, with reference to the case exemplified, is suitable for converting into angular movements of the hook 3 the movements of actuation produced by the actuator 5.
  • the transmission arrangement 6 may be of the type described in the aforementioned patents EP 1640493 A2 and EP 1703212 A2 , the teachings of which in this regard are incorporated herein for reference.
  • a cam for example a three-lobed cam (see Figure 27 , where such a shaft and such a cam are partially visible, designated by 5b and 5c), for producing displacement of a slider, designated by 6a in Figures 2-3 .
  • the slider 6a is constrained to the body 2 so as to be able to slide linearly between two limit positions, and for this purpose the bottom wall 2c of the body 2 preferably defines appendages for positioning and guiding the slider itself.
  • the end of the slider 6a opposite to the actuator 5 preferentially presents a front surface defining an inclined plane, designed to co-operate with a rear part of the hook 3 (this inclined plane may for example be seen in Figure 18 , where it is not designated by any reference number).
  • the shape of the hook 3 may vary from the one exemplified in the figures, in view of its function of co-operating, on the one hand, with a retention element, and, on the other, with an actuation system.
  • the hook 3 has a generally arched rear portion (see, for example, Figure 18 ), having one end with rounded profile, designed to co-operate with the inclined surface of the slider 6a to convert a linear movement into an angular movement, as well as a front engagement portion (see, for example, Figures 1 and 12 ), designed to engage with a retention element that is fixed or defined on the door of the oven.
  • the door is illustrated with a solid line limitedly to the aforesaid retention element, which is designated by 7, and is represented in partially schematic form and with a dashed line only in some of the figures, where it is designated by 101.
  • a torsion spring 4a mounted in a position corresponding to the pin 4 of the hook 3 is a torsion spring 4a, the ends of which react, respectively, against the body 2 and the hook 3, in order to urge the latter into an inoperative position or release position relative to the retention element 7.
  • the system for actuation of the hook 3, i.e., the type of actuator 5 and the corresponding transmission system 6, may be of any suitable type.
  • the locking system comprising the device 1 could have a configuration of assembly that is opposite to the one illustrated, i.e., with the body 2 mounted on the door 101, according to a respective surface of lie or resting surface, and with the retention element 7 on the stationary structure 100.
  • the device 1 is further equipped with at least one sensor, such as the one designated by 8, for example, an optical sensor or else a magnetic sensor or else a microswitch, preferably of a normally closed type, which is connected to the control system of the oven.
  • the device 1 may advantageously be equipped with a connector, such as the one designated by 9, for interfacing the aforesaid sensor to the control system of the oven.
  • Switching of the sensor for example using a microswitch, may be obtained by means of a corresponding actuation element, such as the slider 6a itself or a shaped rod constrained to the body 2 so as to be able to slide linearly.
  • the senor 8 associated to which is a respective actuation or excitation rod 10 has the function of detecting whether the door 101 is in the correct closing position (even irrespective of the position of the hook 3) in order to supply to the control system of the oven a signal for enabling start of an operating program or a program of pyrolitic self-cleaning.
  • a different or further sensor for example, an electromechanical, or optical, or magnetic sensor
  • a signal for enabling start of a program for example the program of pyrolitic self-cleaning
  • a sensor like the one designated by 8' in Figures 2 , 17 and 18 , here in a position underneath the sensor 8, may comprise a microswitch, for example co-operating in a direct or indirect way with the slider 6a (for example, by a relief or cam thereof).
  • both of these sensors concur in supplying to the control system of the oven the signals for enabling start of the operating program.
  • the control system of the oven will supply the actuator 5, for the purposes of movement of the slider 6a and hence of the hook 3, to bring the latter into the respective operative position, or position of locking of the door (in the presence of the further sensor 8", this will be used by the control system for verifying the correct operative position of the hook 3).
  • the rod 10 will occupy an advanced position, by virtue of the action of the corresponding spring 10a, in which position the sensor 8 will be in a safety condition or a condition of opening of the aforesaid circuit, thereby preventing supply of the actuator 5.
  • the device 1 is represented in an inoperative condition, in which the hook 3 is not engaged with the element 7.
  • the door 101 may be brought from its closed position to its open position by manually exerting on the door itself a first opening force, indicated schematically by the arrow F 1 of Figure 12 .
  • the door 101 is articulated in its lower part to the stationary structure of the oven, via known hinges that include respective return springs, which tend to keep the door itself in its closed position.
  • the force F 1 is the one that must be exerted manually on the door by a user to overcome the elastic reaction of the aforesaid return springs. More in general, the force F 1 can be understood as the minimum force necessary that must be applied manually to the door by a user to cause opening thereof, when it is not locked by the hook 3.
  • the torsion spring 4a - when envisaged - urges the hook 3 into the respective inoperative position or release position.
  • the action of the spring 4a is such that, in this condition, the end of the rear portion of the hook 3 is resting on the bottom wall 2c of the body 2, given the retracted condition of the slider 6a (see what is described in EP 1703212 A2 , in relation to operation of the corresponding actuation system).
  • the door 101 is in its closed position: in this way, the door 101 holds the rod 10 in the respective retracted position, countering the action of the spring 10a, so as to keep the sensor 8 in its enabling condition, as explained above.
  • the control system of the oven enables supply of the actuator 5 so that, via the transmission arrangement 6, the hook 3 is brought into the respective operative condition, in which the hook itself is engaged with the retention element 7: in this condition, as illustrated for example in Figure 13 (as well as in Figures 1-3 ), the hook 3 holds the door 101 in its closed position, also against application of the aforesaid opening force F 1 .
  • the actuator 5 is supplied in such a way that the slider 6a of the transmission system 6 advances towards the hook 3 (to the left, as viewed in Figure 12 ), preferably countering the action of a spring (such as the one designated by 6b only in Figure 3 ).
  • a spring such as the one designated by 6b only in Figure 3
  • its inclined front surface Figure 18
  • the hook 3 is induced to move angularly about its pin 4 (in a counterclockwise direction, as viewed in the figures), countering the action of the spring 4a.
  • reaching of the final position of the slider 6a i.e., of the position of engagement or locking of the hook 3 can be detected via a purposely provided sensor (such as the one designated by 8').
  • the aforesaid angular movement of the hook 3 is such that its rear portion lifts, with consequent lowering of its front portion.
  • the end of the front portion of the hook 3 then engages the retention element 7 so as to lock the door 101 in its closing position.
  • the pull or force F 1 possibly exerted on the door does not enable opening of the latter.
  • the shape of the retention element 7 may be different from the one illustrated by way of example.
  • the condition illustrated in Figure 13 is maintained throughout the operating program set by the user or by the control circuit of the apparatus.
  • the control system issues a command for new activation of the actuator 5 in order to obtain a movement of the transmission arrangement 6 opposite to the previous one, i.e., a retraction of the slider 6a (for example, under the action of the spring 6b of Figure 3 ), and hence return of the hook 3 into the position illustrated in Figure 12 .
  • the device 1 thus returns into the respective inoperative position, where the door 101 can be opened by the user by exerting the pull or force F 1 .
  • the device 1 is equipped with a release arrangement, to be used in the case where there is the need to open the door 101 manually, even though the latter is at the moment locked via engagement of the hook 3 with the retention element 7.
  • the aforesaid arrangement may be used - in addition or as an alternative - for the purposes of compensation of possible production and/or assembly tolerances so that the above arrangement could also be defined as "release and/or compensation arrangement”: described in what follows, for clarity of exposition, are first the functions of release and then the functions of compensation of the arrangement in question, which will also be identified for simplicity as “release arrangement” and “compensation arrangement” according to the cases described.
  • the aforesaid release arrangement may be actuated for enabling passage of the hook 3 from its operative condition to a second inoperative condition, in which the hook 3 is not engaged with the retention element 7. More in particular, the release arrangement is prearranged for enabling temporary displacement of the hook 3 from its locking position, i.e., from the operative condition of Figure 13 , to a release position, illustrated in Figure 14 , where the hook 3 is in the aforesaid second inoperative condition. Reaching of the second inoperative condition may be obtained following upon manual application to the door 101 of a second force, indicated schematically by F 2 in Figure 14 , which is greater than the force F 1 mentioned previously.
  • the hook 3 and the retention element 7 have co-operating profiles, shaped in such a way that, following upon the aforesaid application of the force F 2 , a translation upwards of the hook 3 is obtained (allowed by an angular displacement of the body 2 or of a part thereof), until it exits from the corresponding engagement seat of the retention element 7.
  • the release arrangement of the door-locking device 1 comprises an articulation arrangement (where this definition refers to arrangements provided with a fulcrum or some other type of hinge or articulation), which is prearranged for enabling the supporting body 2 (or, as will be seen, at least a first part of the body 2 associated to which are at least the constraint means 4 of the hook 3) to perform angular displacements relative to the stationary structure 100.
  • an articulation arrangement (where this definition refers to arrangements provided with a fulcrum or some other type of hinge or articulation), which is prearranged for enabling the supporting body 2 (or, as will be seen, at least a first part of the body 2 associated to which are at least the constraint means 4 of the hook 3) to perform angular displacements relative to the stationary structure 100.
  • angular movements occur about a second axis of rotation - denoted schematically by X 2 in Figures 3 and 5 - that is substantially parallel to the resting plane P identified by the structure or wall 100 and/or substantially parallel to the axis X 1 of rotation of the hook 3, so as to vary the distance between the axis X 1 of the hook 3 and the resting plane P or the structure 100 that defines it.
  • these angular displacements take place starting from a working or initial angular position of the body 2, in which it lies according to the aforesaid resting plane P.
  • the variations with respect to the above initial position occur following upon manual application to the door 101 of the aforesaid second opening force (or, as will be seen, occur for the purposes of compensation of dimensional tolerances or differences).
  • the release arrangement of the device 1 is also prearranged for elastically urging the supporting body 2 (or the aforesaid first part of the body 2) towards the resting plane P.
  • the supporting body 2, or its aforementioned first part are able to perform the aforesaid angular displacements about a second axis of rotation X 2 , which is substantially parallel to the axis X 1 of rotation of the hook 3, the distance between the axes of rotation X 1 and X 2 being substantially the same in the various operating conditions.
  • the axis of rotation X 2 is here referred to as being "generally” or “substantially” parallel to the resting plane P and/or to the axis X 1 given that, during installation or operation of the device, also minimal movements of rocking or inclination of the aforesaid axis with respect to the plane P are possible. Similar considerations obviously also apply to the axis X 1 .
  • the hook 3 is set in a position corresponding to a generally front or distal portion of the supporting body 2
  • the articulation arrangement designated as a whole by 20
  • the articulation arrangement 20 and the corresponding axis X 2 are hence set in a position substantially opposite to the position of the hook 3 and of the corresponding pin 4 or axis X 1 .
  • the articulation arrangement 20 comprises a movable part 21, which is coupled to a fixed part 22.
  • the movable part 21 is defined by the supporting body 2, but not excluded from the scope of the invention is the case of a movable part configured as a distinct part fixed to the body 2.
  • the fixed part 22 may be configured as an element fixed to the structure or wall 100, or else - as will be seen in relation to other embodiments - be directly defined in the structure or wall 100.
  • the movable part 21 comprises at least one movable hinge element 21a, in particular of a substantially rigid type, which is preferably made of a single piece with the body 2, very preferably projecting from its rear wall 2b.
  • the movable hinge element 21a is shaped to create in an end area thereof a profile in relief, which is at least in part circular or arched.
  • a transverse formation or shape defined for this purpose in the rear area of the movable part 21a is a transverse formation or shape, which forms a sort of fulcrum or hingepin.
  • this shape has an approximately cylindrical outer profile or, as in the case exemplified, is defined by at least two opposed semi-cylindrical portions, which may also have different diameters: these two semi-cylindrical portions are designated by 21a 1 and 21a 2 in Figures 4 and 9 , respectively.
  • the movable element 21a Defined centrally in the same area of the movable element 21a is an axial through seat, designated by 21a 3 in Figures 4 and 8 , which also passes through the aforesaid cylindrical transverse formation 21a 1 -21a 2 .
  • the seat 21a 3 has a diameter or cross-sectional dimension greater than the diameter or cross-sectional dimension of the formation 21a 1 -21a 2 .
  • the fixed part 22 comprises at least one fixed hinge element 23, which is configured for constraining the aforesaid rear end area of the hinge element 21a to the stationary structure 100, in particular via at least one screw 24 or similar fixing member (for example, a rivet).
  • the fixed element 23 has an upper part 23a configured substantially like a small shaped plate, projecting underneath which is a relief 23b, which can be received in the through seat 21a 3 of the fixed hinge element 21a.
  • the relief 23b and the corresponding seat 21a 3 preferentially have a substantially circular cross section and are coupled in a slack way or with play.
  • the lower face of the part 23a of the fixed hinge element 23 defines a transverse seat 23d, for example a substantially semi-cylindrical seat, in which there may be received a substantially complementary part of the movable element 21a, here represented by the upper semi-cylindrical portion 21a 1 of the formation 21a 1 -21a 2 .
  • the upper part of the fixed hinge element 23 preferably also includes front slits 23e for the passage of stiffening ribbings of the movable hinge element 21a (these ribbings being designated by 21b in Figures 4-5 and 8-9 ).
  • the movable hinge element 21 and the fixed hinge element 23 preferably envisage means for mutual engagement, for example to keep the two items in question in position during production steps (for example, prior to fixing with the screw or rivet 24).
  • these mutual-engagement means - which in any case enable mutual angular movement between the elements 21 and 23 - comprise lateral reliefs or teeth 23f of the upper part 23a of the element 23, suitable for engagement in corresponding seats provided on the two opposite sides of the movable element 21a, in particular on the two sides of the formation 21a 1 -21a 2 .
  • the fixed element 23 is set on top of the corresponding end area of the movable element 21a so that the relief 23b penetrates into the seat 21a 3 and the semi-cylindrical profile of the upper portion 21a 1 of the formation 21a 1 -21a 2 couples with the corresponding seat 23d of the fixed element 23.
  • the ribbings 21b of the movable element 21 are received in the corresponding slits 23e of the upper part 23a of the fixed element, and the lateral teeth 23f of the upper part of the fixed element 23 couple with the corresponding lateral seats of the movable element 21a.
  • the cross-sectional dimension or diameter of the through axial seat 21a 3 of the movable element 21a is greater than the corresponding cross-sectional dimension or diameter of the relief 23b of the fixed element 23, whereas the length of the relief 23b is greater than that of the corresponding seat 21a 3 .
  • the element 23 is then secured to the stationary structure 100 by tightening home the screw 24 so that the lower end of the relief 23b bears upon the structure 100.
  • a hole for the screw 24 which may even be of a self-tapping type (this also applies to the other screws or the like referred to hereinafter).
