  • Various types of household appliances are equipped, for reasons of safety, with door-lock devices.
  • washing and/or drying machines whether of the front-loading type or of the top-loading type, are equipped with a door, through which the user has access to a drum for the normal operations of loading and unloading of the laundry.
  • the door-lock device is provided to prevent opening of the door during the cycle of operation of the machine, and, on the other hand, to prevent operation of the machine with the door open.
  • Door-lock devices are typically used also on ovens for cooking equipped with a program or step of pyrolytic self-cleaning, i.e., self-cleaning at a high temperature, to prevent opening of the door of the oven in the course of the aforesaid program, or else to prevent start-up of the program itself in the condition where the door is open or not correctly closed.
  • pyrolytic self-cleaning i.e., self-cleaning at a high temperature
  • the system referred to in the aforementioned prior document in addition to requiring the use of a purposely designed implement, is complex from the standpoint of production and use, moreover requiring a particular arrangement of the household appliance that uses it, such as, for example, the presence of a slit that can alter the aesthetic appearance of the household appliance itself.
  • a door lock unit for household devices having a pawl that co-operates with a door hook and is locked by a control component.
  • the pawl has a pawl body that is moved by the control component and a movable lock that is linked to the pawl body and biased in the lock direction by a spring.
  • the lock can slightly rotates about a pivot pin mounted on the pawl.
  • the lock can also be shifted sideways on the pivot pin, in case manual release of the door lock unit is required, for instance under conditions of electrical power failure.
  • the present invention is aimed at overcoming one or more of the aforesaid drawbacks, and in particular at providing a door-lock device for a household appliance that is simple and inexpensive to make, as well as being easy to use and service.
  • the reference number 1 designates as a whole a door-lock device according to the invention, provided for use on a household appliance equipped with a door.

  • a main body 2 made, for example, of moulded thermoplastic material, designed to be fixed to the cabinet of the oven or in any case to its structure or fixed chassis, the latter being represented only schematically and partially in Figure 2 , where it is designated by M.
  • Fixed with known means to the body 2 is an electrical actuator 3; in the case exemplified, the actuator is constituted by a rotary motor, equipped with terminals 3a for the necessary electrical supply.
  • an eccentric 4 articulated to which, with means in themselves known, is a slider designated as a whole by 5.
  • the slider 5 is constrained to the body 2 so as to be able to slide linearly between two limit positions, as will emerge from what follows.
  • the end wall 2a of the body 2 defines projections for positioning and guiding the slider, some of which designated by 2b in Figure 3 .
  • the end of the slider 5 opposite to the eccentric 4 has a front surface 5a defining an inclined plane designed to co-operate with a movable locking member which, in the case exemplified, is constituted by a catch which can turn through an angle and is designated as a whole by 7, preferably made of metal material.
  • the catch 7 is constrained in a movable way or hinged to the body 2, in particular by means of a pin 8 which extends between two parallel walls 2c of the front portion of the body 2.
  • the cylindrical, preferably metal, pin 8 is a component distinct from the body of the catch 7 and inserted in a transverse through hole of the catch itself.
  • the pin 8 could be formed by two reliefs or protrusions projecting from opposite sides of the body of the catch 7, which are cylindrical and are coaxial with respect to one another.
  • a top wall 2d extends between the aforesaid walls 2c of the body 2.
  • the catch 7 comprises a substantially arched rear portion, designated by 7a in Figure 3 , which has an end with a rounded profile and is designed to co-operate with the inclined surface 5a of the catch 7, and a substantially L-shaped or hook-shaped front portion, designated by 7b, the terminal stretch of which is designed to engage in a respective seat 9a, defined in a door of the oven on which the device 1 is mounted. Said door, represented limitedly to the part in which the seat 9a is formed, is designated by 9 in the figures.
  • the catch 7 is equipped with a transverse through hole, from which there project the ends of the pin 8.
  • the arrangement could be reversed, i.e., with the body 2 fixed to the door and with the seat 9a, or other retention element designed to co-operate with the catch 7, provided in the fixed or movable structure of the household appliance.
  • the device 1 is further equipped with at least one sensor, such as a microswitch of a normally closed type, designated by 10 in Figure 3 , connected or interfaced to the control system of the oven and having a respective sensitive element or feeler 10a, which can be actuated via a corresponding actuation element, such as a shaped rod, designated by 11, constrained to the body 2 so as to be able to slide linearly.
  • a sensor such as a microswitch of a normally closed type, designated by 10 in Figure 3
  • a respective sensitive element or feeler 10a which can be actuated via a corresponding actuation element, such as a shaped rod, designated by 11, constrained to the body 2 so as to be able to slide linearly.
  • a actuation element such as a shaped rod, designated by 11 constrained to the body 2 so as to be able to slide linearly.
  • defined in the end wall 2a of the body are projections for positioning and guiding the rod 11, some of which are designated by 2e in Figure
  • the microswitch 10, with the respective rod 11, has the function of detecting whether the door 9 is in the correct closing position, irrespective of the operative condition of the catch 7, in order to issue a command to the control system of the oven for enabling start up a program of pyrolytic self-cleaning.
  • the door 9 in the position of correct closing, the door 9 maintains the rod 11 in a retracted position, counteracting the action of a spring 12.
  • a projection 11a of the rod 11 is displaced from the feeler 10a in such a way that the microswitch 10 is in a closing condition and thus closes the supply circuit of the motor 3.
  • the control system of the oven will supply the motor 3, to enable movement of the slider 5 and hence of the catch 7 so as to bring the latter into the respective operative position, in which it locks the door 9.
  • the rod 11 will be located in an advanced position by virtue of the action of the spring 12, in which position the projection 11a presses the feeler 10a, keeping the microswitch 10 in the opening position, in which it opens the supply circuit of the motor 3.
  • the control system of the oven will not enable start-up of the program of pyrolytic self-cleaning even in the case of a specific selection in this sense by the user.
  • the lid 13 comprises at least one portion 13a, designed to close at the top the area of the body 2 in which the inclined surface 5a of the slider 5 co-operates with the rear portion 7a of the catch 7.
  • said portion 13a has two symmetrical side projections, one of which designated by 13b, which are designed to extend parallel on the outside of the walls 2c of the body 2, and each have an end designed to be inserted in a respective seat 2f of the body 2.
  • the projections 13b have the function of ensuring correct positioning of the pin 8 in the various conditions of operation of the device 1, as will emerge from what follows.
  • FIG. 4 Illustrated in Figure 4 is just the main body 2 of the device 1, whilst Figure 5 represents a respective enlarged detail thereof corresponding to the area of positioning of the pin 8 of the catch 7, here omitted for reasons of greater clarity.
  • an opening designated as a whole by 14 within which there protrudes, in an intermediate position, an elastically deformable wall portion, which forms a sort of arched tooth or elastic element, designated by 15.
  • a seat designated as a whole by 16, having an external profile substantially shaped like a figure eight, i.e., with the form of two circular holes that intersect one another in a substantially symmetrical way to form a top portion of seat 16a and a bottom portion of seat 16b.
  • the form of the seat 16 is such that, in the area of intersection of the two aforementioned holes, there is formed a restriction 16c.
  • the width of the seat 16 is smaller than the diameter of the pin 8, whilst the circumference of the latter is substantially coincident with, or slightly smaller than, the circumferential profile of each of the seat portions 16a and 16b.
  • a part of the profile of the seat 16 (substantially the left-hand part, in Figure 5 ) is formed in the tooth 15, whilst another part (substantially the right-hand part, in Figure 5 ) is formed in a substantially rigid portion of the wall 2c.
  • the restriction 16c is formed in part in the elastic tooth 15 and in part in said substantially rigid portion of wall 2c.
  • the portion 14a of the opening 14 that extends from the part of the tooth 15 opposite to the seat 16 (the left-hand part of the opening 14, in Figure 5 ) enables elastic deformation of the tooth 15, as will emerge from what follows.
  • the seat 16 is as a whole slightly inclined, with its top portion 16a closer to the part of catch 7b with respect to the bottom portion 16b.
  • An identical and/or symmetrical passage 14, with corresponding tooth 15 and seat 16, is formed in the wall 2c opposite to the one that may be seen in Figures 4 and 5 .
  • the device 1 according to the invention is represented in an inoperative condition, with the door 9 open. It is to be noted that in said figures, as in Figures 9-11 and 12-14 , the lid 13, the rod 11 and some internal components of the device 1, such as the microswitch 10, are not represented for reasons of greater clarity.
  • the pin 8 of the catch 7 extends between the bottom portions 16b of the seats 16 formed in the two walls 2c of the body 2.
  • a torsion spring mounted on the pin 8 is a torsion spring, partially visible in Figures 7 , 10 and 13 where it is designated by 17, the terminal branches 17a and 17b of which react, respectively, against the body 2 and the catch 7 in order to bias the latter in its respective inoperative position or position of release.
  • the action of the spring 17 is such that the end of the rear portion 7a of the catch 7 is set resting upon the end wall 2a of the body 2, given the retracted condition of the slider 5.
  • opening of the door 9 can be performed by applying thereon a tensile force in the direction of normal opening of the door itself, as indicated by the arrow F in Figure 8 .
  • control system enables controlled supply of the motor 3, as previously mentioned with reference to the microswitch 10 and to the rod 11, in order to bring the device 1 into the respective operative condition, or condition of locking of the door 9 in the closed position.
  • the motor 3 is controlled in such a way that its shaft 3b determines an angular movement through 180° of the eccentric 4, with the consequent advance of the slider 5 (towards the right, as viewed in Figure 11 ).
  • its inclined front surface 5a can penetrate underneath the rounded end of the rear portion 7a of the catch 7.
  • the catch 7 is induced to move angularly about the pin 8, countering the action of the spring 17.
  • the end of the portion 7a of the catch 7 comes to rest upon the top surface of the slider 5.
  • the aforesaid angular movement of the catch 7 is such that the rear portion 7a rises, with consequent lowering of the front portion 7b of the catch itself.
  • the end of said front portion 7b then penetrates within the seat 9a of the door 9, blocking the latter in the closing condition.
  • a normal tensile force exerted on the door 9 does not enable opening of the latter.
  • the device 1 is set in the operative condition illustrated in Figures 9-11 , i.e., with the door 9 blocked in the closed position via the catch 7.
  • the release of the device 1 can be obtained manually by virtue of the particular construction of the seat 16 of the pin 8.
  • a tensile force must be exerted on the door 9, i.e., a force must be applied in the direction of normal opening of the door itself, as indicated schematically by the arrow F' of Figure 11 .
  • the device 1 is conceived such that the force F' necessary for obtaining manual release of the device to be considerably greater than the force F required for opening the door 9 in conditions of normal use, i.e., a force such as to meet the safety standards; merely by way of example, for this purpose a tensile force F' of at least 20 kg must be applied to the door 9.
  • the arrangement between the catch 7 and the seat 9a is such that the torque exerted on the door 9 determines a vertical component of force on the catch itself, with the end 7b of the latter that will tend to move angularly in a counterclockwise direction, as viewed in the figures, or upwards.
  • at least some surfaces that co-operate with one another of the end of the portion 7b of the catch 7 and of the seat 9a of the door 9 will be in the form of slightly inclined planes, for the purpose of obtaining the components or forces necessary for the movement of release of the catch 7.
  • the portion 7a of the catch 7 is resting upon the top surface of the slider 5. Consequently, following upon the aforesaid vertical component of force that is applied on the portion 7a (approximately 4 kg, with reference to the aforementioned example of tensile torque F' of approximately 20 kg), the catch 7 tends to behave, as a whole, as a second-class lever, with the point of rest of its portion 7a on the slider 5 that functions as fulcrum.
  • the pin 8 is then biased upwards within its end seats 16, i.e., pushed against the restriction 16c.
  • the angular movement of the catch 7 is limited by the interference between an intermediate area of its portion 7a with the top wall 2d of the body 2, as may be seen in Figure 14 .
  • This fact, together with the inclination of the seat 16, entails the consequence that the force exerted on the pin 8 is unloaded on the teeth 15.
  • the teeth 15 are induced to undergo elastic deformation, towards the portion 14a of the respective passage 14, thus causing an increase in the width of the seat 16 in an area corresponding to the restriction 16c, such as to enable the pin 8 to pass from the bottom portions of seat 16b to the top portions of seat 16a, displacing upwards also the spring 17.
  • the tooth 15 will return elastically into the original position, as may be seen, for example, in Figure 13 .
  • the opening 14, or more in particular the tooth 15 and the seat 16, provide bistable switching means, which can be actuated to bring about translation of the pin 8, and hence of the catch 7, between a position of normal operation and a position of special operation, both being stable.
  • the actuating system formed by the electrical actuator 3, the eccentric 4 and the slider 5 thus enables the catch 7 to be brought from a first inoperative condition ( Figures 6-8 ) to an operative condition ( Figures 9-11 ), whereas, in the position of special operation, the catch 7 assumes a second inoperative condition, in which the catch itself is not engaged with the retention element constituted by the seat 9a.
  • Actuation of the aforesaid switching means which is necessary to bring about said translation from the position of normal operation to the position of special operation, can be obtained by applying on the door, in its normal direction of opening, a force that is considerably greater than the minimum force necessary for opening the door itself when the catch is set in said first inoperative condition illustrated in Figures 6-8 .
  • the device 1 can then be restored manually by a person responsible for carrying out technical assistance on the oven, by first pushing the front portion 7b of the catch 7 downwards.
  • step (as may be seen in Figure 14 in relation to the position of the catch 7 alone), an intermediate stretch of the portion 7a of the catch is in contact with the top wall 2d of the body 2.
  • the catch 7 behaves again as a second-class lever, with the point of rest of the aforesaid intermediate stretch of the portion 7a on the top wall 2d that functions as fulcrum.
  • the projections 13b of the lid 13 illustrated in Figures 1 and 3 when coupled in the respective seats 2f of the body 2, are each set up against a wall 2c, in an area corresponding to the respective seat 16.
  • the projections 13b perform the function of guaranteeing correct position of the pin 8 in its various possible operating conditions, and in particular in the course of passage between the seat portions 16a and 16b, thus preventing them from sliding out of the seat 16 or from being misaligned or inclined.
  • the device 1 according to the invention is simple and inexpensive to produce. It is pointed out in particular that the system that enables manual release of the device is in effect obtained through the particular conformation of the passages 14, and hence of the teeth 15 and of the seat 16, elements that are defined in the course of the operation of moulding of the body 2 made of thermoplastic material.
  • the actuator of the device 1 could be of a type different from the one described previously by way of example.
  • the actuator 3 could also be constituted by a linear actuator.
  • the actuator could be of an electromagnetic type, or else of a thermal or electro-thermal type, for example with operation based upon the use of a material designed to expand and/or contract (such as a wax), or other monostable actuator, or again a bistable actuator, i.e., one able to vary its own operative condition between a stable resting position and a stable working position, according to the presence or otherwise of supply.
  • a bistable mechanism of a known type could be associated thereto, for example as described in EP-A-0 663 633 .
  • the pin 8 and the opening 14 could present a reversed arrangement with respect to the one previously exemplified.
  • the body of the catch 7 could, for example, comprise at least one passage or a transverse slot, shaped to provide the tooth 15 and the seat 16, whilst the axis of rotation could extend between the two walls 2c, or else be constituted by two coaxial cylindrical protrusions, each projecting from a wall 2c.
  • the pin 8 extends between two coaxial holes provided in the two walls 2c of the body 2, in a substantially fixed position (except for the possibility of the pin 8 of rotating about its own axis).
  • the catch designated as a whole by 7', has a central undercut, obtained for example by removal of material, in such a way that there are formed in its body two thin walls that are parallel to one another, designated by 7c in Figures 17 and 20 , which also define at least the front portion 7b of the catch itself.
  • each wall 7c a portion 14' is formed, which, in the case exemplified, comprises a slot with a profile which is substantially similar to that of the opening previously designated by 14, and which consequently has a respective deformable tooth 15 and a seat divided into two portions 16a and 16b.
  • the walls 7c are sufficiently thin to enable the necessary elastic bending of the teeth 15, for the purposes described previously, and the portions 14' of the two walls 7c are in positions substantially specular with respect to one another.
  • the device 1 may in fact be seen in its position of normal operation, in the condition of locking of the door (not represented therein).
  • the top portions of seat 16a of the catch 7' are engaged on the pin 8.
  • the catch 7' may be brought angularly into the respective first inoperative condition, in which the catch itself releases the door.
  • the door-lock device can be brought into the respective position of special operation, by applying on the door a sufficiently high tensile force, with the modalities described previously. In this way, bending of the teeth 15 is obtained with the translation of the catch 7', enabled by the fact that the portions of seat 16b will engage on the pin 8 instead of the portions of seat 16a, as may be seen in Figures 18-20 .
  • the catches used in door-lock devices for household appliances have a full body; for example, this is the case of the embodiment illustrated in Figures 1-14 .
  • the body of the catch 7' is prevalently full, even though it has a central undercut aimed at enabling formation of the two parallel walls 7c, in which the shaped passages 14' for the pin 8 are formed.
  • the embodiment of a catch for a door-lock device having non-full body is proposed, i.e., with a substantially box-shaped structure. Said possibility is illustrated schematically in Figures 21-25 .
  • a locking device or catch suitable for application in a door-lock device for household appliances the body of which is obtained from a plane metal plate 20, shaped in order to obtain a particular perimetral profile and then bent substantially to form a U so as to obtain two parallel side walls 7c, joined to one another by a common or top wall 7d.
  • the opposite ends of the parallel walls 7c are shaped so as to form the rear portion 7a and front portion 7b of the catch itself, which are here each constituted by parallel terminal stretches of the same walls 7c.
  • the terminal stretches of wall 7c have the rounded profile necessary to enable co-operation with the slider 5.
  • the respective terminal stretches of wall 7c are provided with at least one inclined-plane stretch, suitable for co-operating with a surface of the seat 9a of the door 9 described previously, in order to obtain the components or forces necessary for movement of switching of the device.
  • the catch of the device 1 basically has two arms set at angles with respect to one another, which form their respective portions 7a and 7b.
  • the two portions 7a and 7b are, in effect, made just by the end of the side walls 7c, and hence the top surface of the catch 7", represented by the wall 7d, can be substantially plane. This enables the two side walls 7c to be obtained in a convenient way, via simple operations of bending of the plate 20. Obviously, there could advantageously be obtained more complex forms of the catch 7" with further or different shapes and/or bends.
  • each wall 7c formed in each wall 7c is, in an intermediate position, a respective portion 14', with a passage or a slot having a profile substantially similar to that of the opening previously designated by 14, and hence provided with a respective deformable tooth 15 and a seat divided into two portions 16a and 16b.
  • the modalities of use and operation of the catch illustrated in Figures 21-23 are substantially similar to those described with reference to the variant of Figures 15-20 .
  • a plate 20 which can be used for formation of the catch 7", in a plane configuration.
  • Said plate 20 is obtained from a metal sheet or strap, so as to have a peripheral profile conformed to provide the various functional parts of the catch 7", and in particular the portions 7a, 7b and the passages or slots 14' that delimit the respective tooth 15 and seat 16.
  • the aforesaid complex profile of the plate 20 can be obtained via shearing, chemical etching, milling, laser cutting, or any other known technique designed for the purpose.
  • the plate 20 there are preferably formed, with known modalities, also at least two reductions of thickness or longitudinal incisions, preferably but not necessarily parallel, represented schematically by the dashed straight lines in Figures 24 and 25 , aimed at forming preferential lines of bending for the plate itself.
  • said incisions delimit within the plate 20, which is still in a plane configuration, the areas designed to form the walls 7c and 7d.
  • the aforesaid process enables the catch 7" to be obtained in an extremely simple and inexpensive way, via operations that are easily automatable, and with less material than for a catch with a full body.
  • catch 7" can involve slight modifications in the geometry of the body 2 of the device 1 described previously. It is pointed out, for example, that the top wall 2d could be in a position slightly retracted with respect to what has been illustrated previously, in order to enable the catch 7" to make the necessary movements.
