Definitions

  • the present invention belongs to the field of electrical household appliances such as washing machines, dishwashers and/or similar electrical household appliances.
  • the present invention relates to a closing and opening device, in particular for panels, doors or the like, for example of electrical household appliances of the aforesaid type.
  • the present invention relates to a device of the aforesaid type adapted to prevent the accidental opening of a panel or door, for example during the operation of a washing machine, as well as, again in the case of a washing machine or a similar electrical household appliance, to provide the hermetic seal of the panel or door, as well as to allow the easy opening of the panel under special pre-set conditions (for example, when the washing machine or similar electrical household appliance is not in operation).
  • the present invention further relates to a closing and opening system comprising a closing and opening device of the aforesaid type, as well as to an electrical household appliance (for example, a washing machine or a similar electrical household appliance) equipped with a device and/or system of the aforesaid type.
  • a closing and opening system comprising a closing and opening device of the aforesaid type, as well as to an electrical household appliance (for example, a washing machine or a similar electrical household appliance) equipped with a device and/or system of the aforesaid type.
  • the most common closing and opening devices and/or systems employed for electrical household appliances essentially comprise an actual closing (and opening) assembly usually applied to the housing of the electrical household appliance and a striker element usually fixed to the panel of the same electrical household appliance.
  • the closing and opening assembly can be switched between a first closing position and a second opening position, wherein the closing assembly, in the closing position, engages the corresponding striker element stop of the panel, thus securing the closing of the panel itself, while, conversely, in the opening position, it allows the disengagement of the striker element and thus the opening of the panel.
  • Such a known closing and opening device is known from e.g. GB1249117A and WO2010120647A1 .
  • manual switching devices and/or systems are known, i.e. in which the switching of the closing and opening assembly is accomplished manually by a user or operator, devices and/or systems in which the switching of the closing and opening assembly is electromechanically assisted, e.g. by means of small electric motors, solenoids and/or similar components being in fact equally well-known and common.
  • the devices and/or systems according to the prior art have been conceived so as to prevent the accidental opening of the panel, in particular during the operation of the electrical household appliance, for example, in the case of a washing machine, during the washing cycle steps which provide for the presence of water inside the washing machine, wherein, on the other hand, the safety standards also require the possibility of an easy (simple and fast) opening of the panel, in particular, in case of emergencies.
  • an essential requirement is that of ensuring the perfect hermetic seal of the panel so as to prevent water or liquid leakages and/or similar drawbacks.
  • the above objects must be ensured for a prolonged period of time, in particular, even after a minimum number of closing and opening cycles compatible with market needs.
  • closing and opening device and/or system according to the present invention shall be characterized by reduced size and bulk, as well as be applicable to electrical household appliances of the known type according to equally simple and cost-effective modes, as well as not require substantial modifications to said electrical household appliances.
  • the present invention is based on the general consideration according to which it is possible to achieve the above pre-set objects and in particular to meet the functionality and reliability needs in compliance with safety standards by means of a device which provides for two different reciprocal engagement conditions between switching assembly and striker element, the switching assembly and the striker element being simply alternatively engageable (into said first engagement condition) and disengageable (from said first engagement position) by alternatively acting by means of pushing and traction (or internal pushing) on the panel, the switching assembly and the striker element being further alternatively engageable (into said second engagement condition) and disengageable (from said second engagement position) by means of assisted switching of the switching assembly, for example by means of electromechanical means such as electric motors or the like.
  • a further consideration underlying the present invention is that the assisted switching from said first reciprocal engagement condition to said second reciprocal engagement condition (between the switching assembly and the striker element) may be effectively used to obtain an improved reciprocal engagement between the panel and the main body (in particular, the housing) of the electrical household appliance, thus ensuring, for example, the watertight sealing of the panel itself. Furthermore, being the reciprocal disengagement of the striker element and of the switching assembly (from said second position or engagement condition) possible only by means of the activation of said electromechanical means, the accidental opening of the panel, for example in the presence of water in the electrical household appliance, will be prevented.
  • the present invention relates to a closing and opening device for doors and/or panels and/or similar components, in particular of electrical household appliances such as washing machines, dishwashers and similar electrical household appliances, as it is defined in claim 1.
  • said closing and opening assembly comprises first elastic means, where said first switching of said closing and opening element from said first position to said second position is accomplished against the resistance exerted by said elastic means, and where with said striker element at least partially inserted in said closing and opening element through said through opening, said closing and opening element is switched again from said second position substantially to said first position by virtue of the pushing action of said elastic means.
  • a second engagement and switching surface of said closing and opening element engages a second engagement and switching surface of said striker element so as to prevent said striker element from accidentally exiting from said closing and opening element through said through opening, thus preventing the accidental disengagement of said closing and opening assembly from said striker element.
  • At least said second engagement and switching surface of said closing and opening element is shaped so that, with said striker element at least partially inserted through said through opening and with said closing and opening element substantially in said first position, a traction with predefined intensity exerted on said striker element in a direction opposite to the insertion direction results in a further switching of said closing and opening element from said first position to said second position, and therefore in the disengagement of said striker element from said closing and opening assembly.
  • said closing and opening element can be further switched by rotation from said first position to a third position opposite to said second position, where at least said second engagement and switching surface of said closing and opening element is shaped so that, with said striker element at least partially inserted into said closing and opening assembly, the switching of said closing and opening element from said second position to said third position results in a further insertion of said striker element into said closing and opening assembly.
  • said closing and opening element can be switched by rotation from said third position to a fourth position, said fourth position being such as to allow said striker element to exit and/or be extracted from said closing and opening assembly through said through opening of said closing and opening element.
  • the rotation direction for switching said closing and opening element from said third position to said fourth position coincides with the rotation direction for switching from said first position to said third position.
  • said closing and opening assembly further comprises second elastic means, where, with said closing and opening element in each of said third and fourth positions, said second elastic means are elastically engaged by said striker element, and where, with said closing and opening element in said fourth position, the outward movement and/or extraction of said striker element from said closing and opening assembly through said through opening are facilitated by the elastic reaction of said second elastic means.
  • said closing and opening assembly further comprises a switchable operating element coupled to said closing and opening element so that the switching of said operating element results in a switching of said closing and opening element.
  • said operating element can be switched by rotation, where the switching by rotation of said switching element from a first position to a second position and from said second position to a third position results in the switching of said closing and opening element from said first position to said third position and from said third position to said fourth position, respectively.
  • said device comprises electromechanical means for switching said operating element.
  • said electromechanical means comprise an electric motor and one or more transmission elements interposed between said electric motor and said operating element.
  • said operating element comprises a circular serrated ring nut, where said serrated ring nut is engaged by at least one of said transmission elements.
  • the present invention further relates to a closing and opening system for doors and/or panels and/or similar components, in particular of electrical household appliances such as washing machines, dishwashers and similar electrical household appliances, said system comprising a striker element adapted to be rigidly fixed to a said panel, where said system comprises a closing and opening device according to one of the variants and/or embodiments summarized above, where the closing and opening assembly of said device is adapted to alternatively engage and disengage said striker element.
  • the present invention further relates to an electrical household appliance such as, for example, a washing machine, comprising at least one panel, said electrical household appliance comprising a device according to one of the variants and/or embodiments summarized above and a striker element rigidly fixed to said panel.
  • an electrical household appliance such as, for example, a washing machine, comprising at least one panel
  • said electrical household appliance comprising a device according to one of the variants and/or embodiments summarized above and a striker element rigidly fixed to said panel.
  • the present invention finds particular application in the field of electrical household appliances such as washing machines, dishwashers and similar electrical household appliances, this being the reason why, below, the present invention will be described with particular reference to the applications thereof in the field of electrical household appliances, in particular of a washing machine.
  • the present invention finds convenient application in all cases in which the closing and the opening of a panel are required to be reliable, simple, safe, and in accordance with the safety standards.
  • the device according to the embodiment depicted therein is identified by reference numeral 100 and comprises a support base 10 with a through opening as well as, arranged on the base 10, electromechanical means 6, 7 and 8, a closing and opening element 5 housed in a ring nut 3 (the element 5 and the ring nut 3 being assembled together to form a switching assembly 20) as well as a locking ring 2 and an elastic flap 11.
  • the closing and opening element 5, with a circular external peripheral surface is housed inside the ring nut 3, which in turn defines a cylindrical internal surface with a radius substantially corresponding to that of the external surface of the element 5, and which is equipped with an external serration 31.
  • the electromechanical means 6, 7 and 8 essentially comprise a small electric motor 6 on the shaft of which a first pinion 7 is fixed, engaging in turn an intermediate gear 8 (serrated wheel), a third intermediate gear being engaged by the second gear, where the third gear comprises a serrated wheel from which a rotation shaft extends with an external surface comprising a helical groove (in practice, a worm gear) which finally engages the external serration of the ring nut 3.
  • the closing and opening element 5 is housed, as mentioned above, inside the ring nut 3 and is both rotatable with respect to the ring nut 3 (inside a pre-set circular sector) and rotated by the ring nut 3 according to modes clarified below in greater detail.
  • the element 5 further comprises a through opening 30 of shape and size substantially corresponding to those of the opening obtained in the base 10, i.e. with two opposite straight sides joined by two curved sides which are also opposite.
  • First elastic means are interposed between the element 5 and the ring nut 3 (see in particular, for example, Figures from 2 to 5), which essentially consist of a couple of helical clips 4 arranged in symmetrical positions with respect to a transverse symmetry plane, where the element 5 in non-use conditions (resting) is kept pushed in the end-of-stroke position thereof with respect to the ring nut 3 by the action of the two clips 4.
  • reference numeral 9 further identifies a control and management board adjacent the ring nut 3 and comprising external conductive metal foils adapted to be suitably stressed by the ring nut 3 during the rotation thereof, again according to modes clarified below in greater detail.
  • the ring nut 3 in addition to the serration 32, comprises a plurality of protrusions 31 adapted, in fact, to engage, during the rotation of the ring nut 3, the conductive metal foils of the board 9, where the engagement of one or more of the metal foils results in the generation of electrical control signals adapted to be received by a control unit (not depicted in the Figures) belonging to the electrical household appliance equipped with the device 100.
  • Figure 26 shows a plan view thereof, in particular, from the bottom with respect to Figure 1 , from which it appears that the element 5 comprises two opposite tapered (inclined) surfaces 51 extending from the opposite longitudinal edges of the opening 30 tightening towards the inside of the opening 30 itself.
  • the two opposite tapered surfaces 51 of the element 5 will be also defined below as first striker or engagement surfaces of the closing and opening element 5, where, in element 5 a circular bottom will be identified, which defines the opening 30 and is surrounded and delimited by a cylindrical side wall.
  • the bottom surface facing the base 10 (and possibly partially resting on the base 10 itself) is thus substantially flat ( figure 26 ) without the two opposite tapered surfaces 51 described herein.
  • the bottom of the element 5, on the opposite side of the surface resting on the base 10, is instead shaped so as to define two inclined surfaces (for example, as a cam 52) arranged on the sides of the opening 30, where the thickness of the bottom portions underlaid by the two surfaces 52 varies from a minimum thickness to a maximum thickness, and where the two cam (or simply inclined) surfaces 52 are arranged and oriented symmetrically with respect to the opening 30.
  • two inclined surfaces for example, as a cam 52
  • a latch-shaped striker element 11 (substantially "T-shaped”, but not limited to in the embodiment depicted in Figure 1 ) is further depicted therein, where the latch is adapted to be fixed to the panel (not depicted) of an electrical household appliance, for example a washing machine or laundry machine. It is thus apparent that the reciprocal engagement and disengagement of the latch 11 and of the device 100, according to modes clarified below in greater detail, result in the closing and opening of the panel, respectively.
  • the device according to the present invention allows at least two reciprocal engagement modes between the striker element 11 and the device itself, and thus two closing and opening modes, respectively, of the panel provided with the striker element 11; a first reciprocal engagement and disengagement mode will be clarified below with reference to Figures from 2 to 10, in which component parts and/or features of the device 100 according to the present invention already described above with reference to other Figures are identified by the same reference numerals.
  • Figures from 2 to 6 depict the progressive engagement of the striker element 11 and of the device 100, the progressive engagement being obtained, for example, by the panel progressively approaching the electrical household appliance equipped with the device 100.
  • the element 5 is kept in the end-of-stroke position thereof with respect to the ring nut 3 by the springs 4, where, in this situation, the opening 30 of the element 5 is not perfectly aligned with the corresponding opening of the base but, conversely, the bottom of the element 5 at least partially overlaps the opening of the base 10, the opening of the base 10 being thus at least partially obstructed by the element 5 (by the bottom thereof).
  • the striker element 11 is first inserted into the corresponding opening of the base 10, where the engagement surface 111 of the element 11 is put in contact with the surfaces 51 of the element 5 or at least with the portions thereof placed at the opening of the base 10.
  • the reciprocal disengagement between element 11 and device 100 or closing assembly 20 can be achieved by simply acting in traction on the striker element 11 (for example by acting on the panel) in the opposite direction of the engagement or insertion direction.
  • the engagement of the surface 112 with the cam surfaces 52 in case of traction on the element 11, results in a new rotation of the element 5 in a counterclockwise direction, with the consequent substantial alignment of the opening 30 with the opening of the base 10 (and thus with the transverse part of the element 11), and thus with the possibility of extracting the element 11 through the opening 30 and the opening of the base 10, where again by virtue of the action of the springs 4, the reciprocal disengagement between the striker element 11 and the closing element 5, results in a further rotation (in the clockwise direction) of the element 5, which is thus re-positioned in the starting configuration, in which the closing element 5 is in the end-of-stroke position thereof with respect to the ring nut 3 and partially obstructs the opening
  • the disengagement modes (and thus the opening modes of the panel) described above ensure both a simplified and immediate opening of the panel (for example when the electrical household appliance is to be loaded), and the appropriate guarantees in terms of safety, for example, in emergency conditions, in particular, being the opening of the panel possible according to similar modes, also acting by pushing on the panel from the inside of the electrical household appliance, for example in the unfortunately frequent case of a child trapped in the electrical household appliance.
  • the activation of the starter motor 6, for example automatically controlled by the start of the washing program results in a rotation of each of the transmission elements, and thus also of the ring nut 3, in particular in a clockwise direction; the rotation of the ring nut 3 in the clockwise direction (note the different arrangement of the protrusions 31 with respect to the control board 9) results first in a progressive compression of the clips 4 (possibly already partially compressed) but also in a progressive feeding, in the clockwise direction, of the element 5, which thus results ( Figure 12 ) in a progressive engagement of the surfaces 52 with the surface 112 of the striker element 11 and thus in the further movement, in the insertion direction, of the element 11 with respect to the element 5, and thus, by virtue of the shape of the surfaces 52, in the progressive approach of the panel to the electrical household appliance, with the subsequent progressive compression of the elastic gasket (if present) interposed between the panel and the electrical household appliance.
  • a closing and opening device which allows for a reliable closing (in particular, hermetic and not subject to accidental and/or unwanted openings) of the panel, while allowing, in case of emergencies, but not only, for a quick, easy and automatic opening of the panel.
  • the above objects are achieved and ensured for a prolonged period of time, in particular, even after a minimum number of closing and opening cycles compatible with market needs, where the device according to the present invention may be achieved by means of simple and therefore cost-effective manufacturing methods, is characterized by reduced size and bulk, and is applicable to electrical household appliances of the known type according to equally simple and cost-effective modes, and does not require substantial modifications to said electrical household appliances.
  • a protective lid (not shown in the Figures) may be included, possibly to replace the ring 2, and thus, in this case, with both protection and fixing functions.
  • the electromechanical means for the assisted switching may be entirely or partially omitted and/or replaced by equivalent components such as transmission belts or the like, the device according to the present invention being however arranged for the manual switching of the closing element 5 by means of the ring nut 5 or, alternatively, directly.
