Description
- The present invention relates to a door-lock device for a household appliance door. More specifically, the invention concerns a door-lock device for washing machines and household appliances in general, designed and manufactured to minimize the dimensions occupied. In the following, the description will be directed to the use in a washing machine, but it is clear that the same should not be considered limited to this specific use. As it is well known, at present there are different kinds of door-lock devices, e.g. for washing machines, capable to prevent the opening of the door until the operation cycle of the household appliance is not ended. An example of a door lock device is known from the patent application
DE102006007418 A1 which discloses a door lock device according to the preamble ofclaim 1. Another example of a door lock device is known from the patent applicationEP1469147A2 , which comprises a slider and a locking hook. - In general, such devices are electromechanical and occupy a significant space, even for the necessary toughnes that they must have. However, the trend to the reduction of the size of household appliances in the field moves the household appliances manufacturers to reduce the size of even these devices. However, reducing the size of the devices already known would risk of making them too delicate and not very robust, thus unsafe. Instead, in case of use of more robust materials, such as metallic alloys, it would increase the cost of the final device.
- Moreover, size reduction implies low tolerances between the components, which, therefore, imply a further increase in production cost. In light of the above, it is an object of the present invention, therefore, to provide a door-lock device for a household appliance that is robust but has reduced dimensions, in particular that it is thin. These and other results are obtained according to the invention with a particular assembly and kinematics of the mechanical unit that holds engaged the door prong of the household appliance, when this is in operation.
- Therefore, according to the present invention a door lock device for a household appliance door is provided, said door being provided with a locking prong, said door lock device comprising a slider capable to assume a resting position and an operating position, a strut, a locking hook capable to interact with said locking prong, rotatably coupled with an end of said slider and cinematically connected with said strut, and pushing means, characterized in that said slider is provided with an internal compartment, in that said strut is placed in said compartment and slidable in it along said slider, and in that said pushing means are placed within said compartment of said slider, arranged to exert a force on said strut so as to keep said strut in contact with said locking hook, so that when said prong interacts with said locking hook, said locking hook rotates and translates, engaging with said locking prong, and remaining engaged with said locking prong by the force exerted by said pushing means through said strut, so that said slider passes from said resting position to said operating position.
- Always according to the invention, said kinematic connection between said strut and said locking hook could be realized by a suitable shaping of the contact surfaces of said strut and said locking hook respectively.
- Still according to the invention, said door lock device could comprise an electronic unit comprising electrical terminals for the connection to a control unit of said household appliance, and a locking pin, capable to assume: an extracted position, in which said locking pin engages with said slider when it is in said operating position, so as to inhibit the return to said resting position, and wherein said electronic unit enables said household appliance to be activated; and a retracted position in which said locking pin is disengaged from said slider.
- Advantageously according to the invention, said slider could have an opening in which said locking pin is engageable with said opening.
- Further according to the invention, said slider could include a wing whereon said opening is obtained.
- Always according to the invention, said pushing means could comprise a spring, arranged in compression, so as to exert a force on said strut. Still according to the invention, said door lock device could comprise adjustment means of the compression of said spring.
- Further according to the invention, said slider could have a seat, and said adjusting means could include a plate, arranged in said seat, said plate having a threaded hole, and a grain, engaged with said threaded hole of said plate, said spring being arranged between said grain and said strut.
- The present invention will be now described, for illustrative but not limitative purposes, according to its preferred embodiments, with particular reference to the figures of the enclosed drawings, wherein:
-
figure 1 shows an exploded view of the door-lock device for a door of a household appliance according to the present invention; -
figure 2 shows a first perspective view of the open device according tofigure 1 ; -
figure 3 shows the device according tofigure 2 in which it is applied a containment enclosure; -
figure 4 shows a second perspective view of the open device according tofigure 1 ; -

figure 7 shows a sectional side view of a device according to the invention when the door is closed, and -
figure 8 shows a sectional side view of a device according to the invention when the door is closed. - In the various figures, similar parts will be indicated by the same reference numbers.
- Making reference to
figures 1 - 5 , the structure of a door-lock device 1 according to the present invention can be seen. Said door-lock device 1 comprises acontainment enclosure 20, in which anelectronic unit 30 and a blockingmechanical unit 40 of aprong 50, integral with a door of a household appliance, is housed. - Said
containment enclosure 20 comprises a first 21 and a second 22 element. Saidfirst element 21 has a first opening 21', for the introduction of theprong 50, so that it may interact with the blockingmechanical unit 40, and asecond opening 21", whose function will be better explained in the following. - Said
electronic unit 30 has theelectric terminals 31 for connecting with the control unit of the household appliance (not shown in the figures). Saidelectronic unit 30 also includes a lockingpin 32, capable of assuming a retracted position, in which saidelectronic unit 30 prevents said household appliance to activate, and an extracted position, in which saidelectronic unit 30 allows said household appliance to operate. - Said blocking
mechanical unit 40 comprises aslider 41, internally hollow, in which aninner compartment 411 is identified. Saidslider 41 also has awing 412 on which anopening 413 is obtained, wherein said lockingpin 32 of saidelectronic unit 30 is insertable. Saidslider 41 is capable of assuming a resting position and an operating position, which will be better described below. - Moreover, said blocking
mechanical unit 40 comprises a lockinghook 42 rotatably engaged to a first end of saidslider 41 by a pin 42'. Said lockinghook 42 is arranged in correspondence to said first opening 21'. Said lockinghook 42 is engageable with saidprong 50. - Said blocking
mechanical unit 40 further comprises astrut 43, slidable within saidcompartment 411 of saidslider 41. Said lockinghook 42 and saidstrut 43 are cinematically connected. In particular, said kinematic connection is realized by a suitable shaping of the contact surfaces 431 and 421 respectively of saidstrut 43 and of said lockinghook 42. - The blocking mechanical unit also comprises a
plate 44, insertable into acorresponding seat 414 of saidslider 41, placed substantially near the second end of saidslider 41, opposite to said first end. Saidplate 44 has a threaded hole, in which agrain 45 is engageable by screwing. Finally, between saidgrain 45 and said strut, aspring 46, or thrust means in general, is interposed in compression. By the adjustment of the insertion of saidgrain 45 in saidplate 44 the compression of thespring 46 is possible to adjust and therefore the force exerted by it on saidstrut 43, to keep it in contact with said lockinghook 42. - The operation of the
door lock device 1 described above is as follows. - When the door is opened and, therefore, the
prong 50 is disengaged from said blocking mechanical unit 40 (seefigure 6 ), the lockinghook 42 is in the initial position shown, in which it is held by the action of thespring 46 on thestrut 43. Also, in this initial position, theslider 41 is in said resting position, in which it is arranged in such a way that theopening 413 is not arranged overlapped to said lockingpin 32, thus holding it in said retracted position, in which, as said above, the household appliance cannot be activated. - Closing the door,
prong 50 moves in the direction of arrow A, fitting into said first opening 21' and intercepting said hook 42 (seefigure 7 ), thus causing, as a consequence of the shaping of said contact surfaces 431 and 421 respectively of saidstrut 43 and of said lockinghook 42, the rotation of the lockinghook 42 with respect to saidslider 41, according to the arrow B, and the translation always of saidhook 42. Being said lockinghook 42 rotatably coupled with saidslider 41, there is also a translation of saidslider 41, which passes from said resting position to said operative position, as effect due to the translation of said lockinghook 42. In particular, once the introduction of theprong 50, the lockinghook 42 arranges (seefigure 8 ) in such way that theopening 413 is is overlapped to said lockingpin 32, thus releasing and allowing the passage of the same from said retracted position to said extended position. Moreover, when said lockingpin 32 is in said extended position and inserted in saidopening 413, saidslider 41 cannot slide, therefore the prong cannot be disengaged from saidhook 42 and therefore said door is closed, even forcing the opening, when the household appliance is in operation, as it is appropriate for safety reasons. Moreover, said lockinghook 42 is kept in the desired position by the action of thestrut 43/spring 46 on the lockinghook 42, as said locking hook cannot rotate back to its initial position, unless in case of sufficient force on the door to open it, due to the shaping of the contact surfaces 431 and 421 respectively of saidstrut 43 and of said lockinghook 42. - Even opening 21" of said
containment enclosure 20 is arranged overlapped on said lockingpin 32 and it is intended to be controlled from the outside or for a possible manual reset. - Then, when the household appliance has stopped working, locking
pin 32 is retracted by a suitable electronic control of the control unit of the household appliance to saidelectronic unit 30, thus releasing theslider 41. Opening the door,prong 50 is disengaged from said lockinghook 42 by means of a sufficient force, suitable to overcome the force of theassembly strut 43/spring 46 on the lockinghook 42. The mechanism makes, this time in the opposite way, the same kinematic movement described above, by rotating and translating, thus translating alsoslider 41, which arranges again in such way that opening 413 does not overlap said lockingpin 32, i.e. passes from said operating position to said resting position. - An advantage of the present invention is that the configuration of the components allows a reduced thickness of the door-lock device and a minimum dispersion of opening and closing forces. This is achieved in particular because the prong of the door causes a roto-translation movement of the locking hook and the elements that contribute to distribute the opening and closing forces (the spring and the strut) are integrated and contained witin the element that realizes the interlock (the slider).
- A further advantage of the present invention is a reduced impact of mutual positioning tolerances among the components.
- The present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is to be understood that modifications and/or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
