Definitions

  • the present invention relates to a door-lock device for a household appliance, in particular an oven.
  • 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. Similar safety devices are also used for preventing the door being opened by small children, during normal operation of the oven.
  • the devices of the type referred to above usually comprise a main body to which there are associated a movable locking member and the actuation system thereof.
  • the main body is fastened to the fixed structure of the household appliance, with the locking member that is designed to co-operate with a retention element of the door; in some instances, the main body of the device is fastened to the door, and the retention element is associated to the fixed structure.
  • the locking system thus requires co-operation of members assembled on different parts of the structure of the household appliance, one part being movable with respect to another part.
  • the locking member and the retention element thereof have to co-operate in a precise manner, i.e., consistently with the design specifications.
  • This requirement imposes the need for particular care and precision in assembly of the components of the locking system on the respective parts of the household appliance, as well as in assembly of said parts with respect to one another (i.e., the door with respect to the fixed structure of the appliance), which leads to an increase in the production times.
  • the fmal position of the locking member with respect to the retention element differs to some extent from the optimal one, or does not guarantee proper and safe operation of the device over time.
  • imprecise positioning between the parts may, on the other hand, fail to be detected immediately if the device, during product testing, temporarily operates as it should; in such cases, the problems deriving from the imprecise positioning of parts involved can emerge at a later date, for example when the product is installed, or after a certain period of use, on account of even minimal settling of the structure of the household appliance or of its the components (such as the door hinges).
  • a bistable actuating system is known, actuated via a wax electrothermal actuator, which can be used in combination with a door-lock device for a household appliance.
  • the device described can be released manually, via a purposely provided mechanical system, should the need arise, for example in the case of absence of mains supply or malfunctioning of the control system of the household appliance.
  • Said system comprises a slit formed in the casing of the device, accessible from outside the household appliance, in which the end of a purposely provided implement can be inserted for the purpose of re-setting or modifying the working condition of the device itself, enabling passage thereof into a respective position of release of the door.
  • 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.
  • the present invention is aimed at overcoming one or more of the aforesaid drawbacks by providing a door-lock device for a household appliance that is simple and inexpensive to manufacture, as well as easy and quick to install and 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.
  • said household appliance is an oven for cooking and that the device 1 is provided for locking the door of the oven in the respective condition of closing when an operation program or a program of pyrolytic self-cleaning is run.
  • the device 1 comprises 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 fixed structure or chassis, the latter being represented only schematically and partially in Figure 2, where it is designated by M.
  • An electric actuator 3 is fixed with known means to the body 2; in the case exemplified, the actuator is constituted by a rotary motor, equipped with terminals 3a for the necessary electrical supply.
  • an eccentric 4 for instance a three-lobed cam, designed to bring about the displacement of a slider, designated as a whole by 5 in Figure 3 (the shaft and the eccentric are shown in Figures 13, 16 and 24, where they are designated by 3b and 4).
  • 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 are 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, said locking member being 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.
  • 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 slider 5, 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 assembled. 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 provided 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, for instance 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; for this purpose, projections are defined in the end wall 2a of the body, for positioning and guiding the rod 11, some of which are designated by 2e in Figure 3.
  • a microswitch for instance of a normally closed type, designated by 10 in Figure 3
  • 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
  • projections are defined in the end wall 2a of the body, for positioning and guiding the rod 11, some of which are designated by 2e in Figure 3.
  • 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 of an operation program or a program of pyrolytic self-cleaning.
  • the door 9 maintains the rod 11 in a retracted position, counteracting the action of a spring 12.
  • an appendage 11a of the rod 11 is displaced from the feeler 10a in such a way that the microswitch 10 enables supply of the motor 3 (in the case of a microswitch 10 of the normally closed type, when the appendage 11a does not press the feeler 10a, the supply circuit is closed); in this condition, in the case where the user selects a program and/or pyrolytic self-cleaning, 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 appendage 11 a presses the feeler 10a, leaving the microswitch 10 free or 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 and/or pyrolytic self-cleaning even in the case of a specific selection in this sense by the user.
  • the reference number 13 designates as a whole a lid, which is not represented in Figure 3.
  • the lid 13 comprises at least one portion 13a, designed to close at the top the area of the body 2 extending between the walls 2c, where the inclined surface 5a of the slider 5 co-operates with the rear portion 7a of the catch 7.
  • said portion 13a of the lid 13 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 preferably each having a lower end designed for hooking in a respective seat formed in the bottom wall of body 2 (not shown).
  • 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.
  • a seat or housing 14 is formed in the side wall 32c.
  • said housing is vertical or, in more general terms, it extends in a direction that is substantially perpendicular to the axis of the pin 8.
  • the housing 14 is delimited at the top by a wall portion 2c' and inside it an elastic element is positioned, in the example shown, a helical spring 15.
  • one end of the spring 15 rests on the surface of the wall portion 2c', whereas the opposite end rests on an end portion of the pin 8 that protrudes within the housing 14.
  • An arrangement similar to the one shown in Figure 4 is provided at both of the walls 2c.
  • Figures 5 and 6 show only the main body 2 of the device 1, in a side view and a plan view, respectively (note that, in Figure 6, projections 2b and 2e, as well as some further positioning and fixing elements formed in the body 2 are not represented).
  • Figure 7 shows an enlarged detail of Figure 5, at a housing 14.
  • Figure 8 illustrates instead a cross section of Figure 6, substantially according to the axis VIII-VIII.
  • each housing 14 is substantially constituted by a cavity formed within the respective wall 2c. Said cavity is delimited, at the rear part thereof, by a vertical wall portion 2c", wherein a through opening or seat is formed, hereinafter also referred to as "slot" and designated by 16, having a generally oblong section of passage or profile.
  • the pin 8 When the pin 8 is assembled, as may be noted for instance in Figure 8, it extends through the two slot-shaped seats 16 so that the respective end portions are each within a housing 14. In this way, with the springs 15 in position, each of them is operatively set between a respective upper wall portion 2c' and an end region of the pin 8.
  • FIGs 10-13 the device 1 according to the invention is represented in a normal operative condition, with the door 9 open. It should be noted that in some of said figures, as well as in some of Figures 14-16 and 21-24, the lid 13, the rod 11 and certain internal components of the device 1, such as the microswitch 10, are not represented.
  • 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 of the eccentric 4 (through about 120° with an eccentric 4 having a three-lobed cam), with the consequent advance of the slider 5 (towards the right, as viewed in Figure 16).
  • 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 17a-17b.
  • the end of the portion 7a of the catch 7 comes to rest upon the top surface of the slider 5.
  • reaching of the closing position by the slider 5 is detected by a microswitch, partially visible in Figure 3, where it is designated by 10'.
  • 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, resting on the bottom thereof, blocking the door in the closing condition; in said condition, as represented in Figures 14-18, a normal tensile force exerted on the door 9 does not enable opening of the latter.
  • Figures 17-20 the device 1 according to the invention is represented in two different possible conditions, always in a locking position.
  • Figures 17 and 19 refer in particular to a condition of installation of the parts similar to that of Figures 14-16 (and hence of Figures 10-13). We shall assume that said condition regards the case of correct installation both of the device 1 on the structure of the household appliance and of the door 9 with respect to said structure.
  • Figures 18 and 20 regard, instead, a situation in which, for example, on account of production and/or assembly allowances, one or more of the parts represented are assembled in a slightly different way as compared to that of Figures 17 and 19.
  • the bottom of the seat 9a lies on a plane higher than that of Figure 17, or at a greater distance from the wall 2a of the body 2.
  • the two different positioning heights are designated by X and Y in Figures 17 and 19.
  • the arrangement according to the invention enables, instead, independent compensation of any possible imprecise relative positioning of the parts involved ⁇ in particular between the body 2, the structure M, the door 9, and the seat 9a ⁇ thus guaranteeing precise and safe operation over time.
  • Said compensation is obtained by enabling the pin 8 to perform controlled displacements within the oblong seats 16, countering the action of the elastic means 15 tending to keep the pin itself in the operating position that has been reached.
  • the device 1 is provided with release means, to be used in situations where the need arises to release the door manually.
  • said means are the same that allow recovery or compensation of any possible imprecision in positioning of the components, i.e., the pin 8, the seats 16, and the springs 15, with their corresponding housings 14.
  • the device 1 is in the operating condition illustrated in Figures 14-16, i.e., with the door 9 blocked in its closed position by means of the catch 7.
  • the motor 3 is not in a condition to operate in the way described above, release of the device 1 can be obtained manually, on account of the particular way in which the seats 16 are made and on account of the presence of the elastic means constituted by the two springs 15, which operate in their respective housings 14.
  • a tensile force must be exerted on the door 9, i.e., a force in the direction of normal opening of the door itself, as indicated schematically by the arrow F' in Figure 16.
  • the device 1 is conceived in such a way that the force F' necessary for obtaining manual release of the device is considerably higher 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 parameters.
  • a tensile force F' of at least 20 kg must be applied on the door 9.
  • the arrangement between the catch 7 and the seats 9 is such that the torque exerted on the door 9 will determine 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 of the mutually co-operating surfaces of the end of the portion 7b of the catch 7 and of the seat 9a of the door 9 will be shaped as slightly inclined planes, in order to obtain the components or forces necessary for the movement of release of the catch 7.
  • the portion 7a of the catch 7 is resting on 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 example cited of a tensile force 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, which functions as fulcrum.
  • the pin 8 is thus loaded upwards within the slot-shaped seats 16, or rather its end areas are pushed in the direction of the top profile of the seats themselves. Also in this case, then, a load is applied on the springs 15 such as to cause yielding or compression thereof, with the progressive displacement upwards of the pin 8, until its end areas come at the most into contact with the top profile of the slot-shaped seats 16, as may be seen in Figure 22 and in greater detail in Figure 23, where the spring 15 is not represented.
  • the translation of the pin 8 upwards has the effect of displacing also the spring 17a-17b upwards.
  • the slot-shaped seats 16 may be shaped in such a way (for example, with a slight narrowing) as to prevent the pin 8 from coming into contact with said profile, even in the limit conditions, in order to leave a safety margin.
  • the housings 14, with the respective springs 15 and seats 16 thus constitute also temporary-release means, designed to enable momentary translation of the pin 8, and hence of the catch 7, between a position of normal operation and a position of special operation.
  • the actuating system provided by the electric actuator 3, the eccentric 4 and the slider 5 enables the catch 7 to be brought from a first inoperative condition ( Figures 10-13) to an operative condition ( Figures 14-16), whereas in the position of special operation the catch 7 assumes a second inoperative condition, in which the catch itself is not engaged by the retention element constituted by the seat 9a.
  • Actuation of the aforesaid release 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 higher than the minimum force necessary for opening the door itself when the catch is in said first inoperative condition represented in Figures 10-13.
  • Restoring of the device 1 into the condition of normal operation then occurs in an automatic or independent way as a result of the elastic reaction of the springs 15, which will push the pin 8 downwards again, until it returns to resting on the bottom profile of the slot-shaped seats 16, thus eliminating any need for intervention on the part of specialized staff to restore proper operation of the device 1.
  • the projections 13b of the lid 13 illustrated in Figures 1 and 2 when coupled in their respective seats on the body 2, are each set up against a wall 2c, in a position corresponding to the respective seat 14.
  • the projections 13b contribute to the function of guaranteeing the correct position of the pin 8 and/or of the springs 15 in the various possible operating conditions, and in particular in the course of passage between the positions represented in Figures 12 and 19, thus preventing them from being slid out of the slots 16, or from being misaligned or slanted.
  • Proper positioning of the springs 15 is on the other hand substantially guaranteed also by the conformation of the housings 14.
  • the device 1 according to the invention is easy to build and economically advantageous. It is pointed out, in particular, that the system, which is designed to enable both compensation of any possible imprecision in the course of assembly and manual release of the device, is in effect obtained through the particular conformation of the seats 16, of the housings 14, and of the springs 15, said seats and housings being elements that can be obtained during the operation of moulding of the body 2 using thermoplastic material, the springs being on the other hand components that are commercially available at a minimal cost.
  • Manual release of the device does not render necessary the use of specific implements and can be obtained in an extremely convenient way directly by the user of the electrical household appliance, should the need arise.
  • the subsequent step of restoration of the device 1 is obtained independently or automatically, without any need for specific operations, replacement of components of the mechanism, or intervention of specialized staff.
  • the actuator of the device 1 could be of a different type from the one described herein by way of example.
  • the actuator 3 could also be a linear actuator.
  • the actuator could be of an electromagnetic type, or a thermal type, or an electrothermal type, for example with its 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 that is able to vary its own operating condition between a stable resting position and a stable working position, according to the presence or otherwise of a power supply.
  • a bistable actuator i.e., one that is able to vary its own operating condition between a stable resting position and a stable working position, according to the presence or otherwise of a power supply.
  • this could be associated to a bistable mechanism of a known type, for example as described in EP-A-0 663 633 .
  • the springs 15 could possibly be positioned facing the inside of the body 2, or else in the direction of the catch 7.
  • the housings for the springs may be obtained in the part of the walls 2c facing the pin 8.
  • each end of the pin 8 does not need to project on the outside, beyond the profile of the respective slot-shaped seat 16; the seats 16 may hence be closed or present a blind recess or groove (for example, in the form of guides or furrows formed on the inside of the walls 2c), and hence not configured as through holes.
