Definitions

  • the invention relates to a security door lock for household appliances with a locking element attached to the door and a spring-loaded counter-locking element attached to the door opening on the household appliance, in which the locking element and the counter-locking element assume a locking position in the closed position of the door, which can be released again with a predetermined force , especially for tumble dryers.
  • the counter-locking element designed as a slide and the spring element are accommodated in a stop bar, that an additional, adjustable in at least two positions securing element is mounted in the stop bar that the slide in one position of the securing element in a breakthrough for the locking element designed as a locking hook protrudes and is held in a spring-loaded working position for closing the door, and that in the other position of the securing element, the slide and / or the spring element are adjusted so that the spring-loaded working position of the slide is canceled and thus a Maintaining the closed position of the door is prevented.
  • the closing of the door preceding the start-up of the household appliance is additionally secured in a simple manner, because as long as the securing element does not assume the correct position, the door cannot be closed.
  • the securing element is set in such a way that the slide and the locking hook cannot be brought into the locking position and thus the door cannot be brought into the closed position.
  • the securing element must first be set so that the slide is spring-loaded and Snap into place behind the locking hook and thus keep the door in the closed position. In this way, the closing of the door is also childproof, because two independent adjustment processes are required to close the door. If the door is provided with a door contact, this can prepare the commissioning of the household appliance after the door is closed. Commissioning takes place with a separate switching means, such as a switch, button or the like.
  • the securing element can be easily removed, so that the safety lock can also be used in the conventional manner.
  • a constructive solution for child safety of the security door lock is characterized in that the slide is supported against the breakthrough by means of the spring element on a control attachment of the securing element and is held on a stop of the stop bar in the spring-loaded working position, and that the control attachment defines the positions of the securing element Control curve, which has different positions in the positions to the axis of rotation of the rotatably mounted securing element.
  • the control cam In the spring-loaded working position, the control cam is at a greater distance from the axis of rotation of the securing element, so that the slider is adjusted via the spring element in such a way that it projects into the opening of the stop bar in a spring-loaded manner. If the securing element is rotated, for example, by 90 °, then the control cam is at a smaller distance from the axis of rotation, so that the slide and the spring element are supported so that the slide can be guided out of the opening in the stop bar without having a locking effect on the locking hook can. The door can therefore not be kept in the closed position.
  • the design of the security door lock can be simplified even further in that the spring element is designed as a spring tab integrally molded on the slide, which is supported on the control curve of the star attachment of the securing element.
  • Another structural design of the security door lock is characterized in that the slide is supported against the breakthrough by means of the spring element on a shoulder or stop of the stop bar, that the slide is extended with a frame-like approach beyond the breakthrough and with this on a control approach of the in the stop bar rotatably mounted securing element and that the control approach has a control cam defining the positions of the securing element, which has a different distance from the axis of rotation of the securing element in the positions.
  • the slide itself is adjusted because it is supported on the control cam of the control attachment of the securing element.
  • the slide is clearly set even in the canceled working position.
  • the cushioning of the slide is achieved in a simple manner in that the spring element is designed as a helical spring which is guided on a bolt-shaped extension of the slide and is supported on the slide and on the shoulder or shoulder of the stop bar.
  • the Breakthrough in the stop bar is rectangular and aligned with its longitudinal dimension in the longitudinal direction of the stop bar
  • the opening of the frame-like extension of the slide is also rectangular and has a longitudinal dimension that is greater than the longitudinal dimension of the opening
  • the dimension of the opening of the frame-like Approach of the slider perpendicular to the longitudinal direction of the stop bar is equal to or smaller than the assigned dimension of the opening, but is greater than the thickness of the locking hook.
  • the securing element on the front side facing the stop bar has a reduced diameter approach with a round cross-section, which is inserted from behind into a hole in the stop bar and is rotatably mounted therein.
  • the securing element is held in the stop bar. This can be achieved in the simplest way when attaching the stop bar to the household appliance or by attaching the slide.
  • the slide can be guided and held by additional guide strips of the stop bar.
  • the stop bar can be used for both left and right-hinged doors, the method of child safety being always observed.
  • a further embodiment provides that the stop bar is provided with two fastening receptacles, the spacing of which corresponds to the distance between the fastening receptacles of a door hinge, with which the door is hinged to the household appliance, and that the stop bar can be attached to the household appliance in two positions rotated by 180 °.
  • the new security door lock is particularly advantageous if it is additionally provided that the door is provided with a door contact, via which the commissioning of the household appliance is prepared and can be initiated by means of a switching means, such as a switch, button or the like.
  • the drum 11 which has a large filling opening 5, is accommodated above the base region 14.
  • the filling opening 5 can be closed by means of the door 6.
  • the switching and control panel 15 is arranged above the drum 11 with the door 6.
  • the door 6 is hinged to the tumble dryer by means of a door hinge, specifically to a bearing neck 12.
  • the door hinge has two fastening receptacles 4.
  • a latching hook 3 is attached to the door hinge on the inside of the door 6 and can also be part of the handle 8.
  • a contact pin 7 or 7.1 can be attached to the inside of the door 6 on one or the other horizontal side, which controls the door contact accommodated in the filling opening 5 in the closed position of the door 6, as shown in FIG. 2.
  • the filling opening 5 carries a stop bar 20 opposite the door hinge, which is designed as a safety door lock and cooperates with the latching hook 3, as will be shown.
  • the stop bar 20 also has two fastening receptacles 4, the spacing of which corresponds to the spacing of the fastening receptacles 4 of the door hinge 9. In this way it is easily possible to strike the door 6 on the left or right of the filling opening 5. As positions 7 and 7.1 of the contact pin show, the contact pin the horizontal side selected, which faces the door contact in the case of the door 6 selected in each case.
  • the door hinge 9 and the stop bar 20 can be attached to each side of the filling opening 5, since both are fastened in the same way.
  • a first embodiment of a stop bar 20 is shown, which is itself child-resistant as a safety lock.
  • the locking hook 3 is attached, which can be inserted into a rectangular opening 21 of the stop bar 20.
  • the narrow sides of the latching hook 3 are provided symmetrically with respect to the central axis with a snap-in and snap-out bevel so that it can cooperate with the slider 22 accommodated in the stop bar 20 in any type of stop.
  • the slide 22 is guided and held adjustably in the longitudinal direction of the stop bar 20.
  • a spring element 26 in the form of two spring tabs is formed on the opening 21 on the slide 22.
  • spring tabs are supported on a control shoulder 28 of an additional securing element 25, which is rotatably mounted outside the opening 21 in a bore in the stop bar 20.
  • the securing element 25 is inserted into the bore of the stop bar 20 from behind and is held captively.
  • the front end of the securing element 25 can have a reduced-diameter end which is inserted into the bore and is rotatably mounted therein.
  • the rear rear side of the securing element 25 can be held by a cover plate or by attaching it to the filling opening 5. It is also possible for the spring element 26 to hold the securing element 25 captively when it is supported on the control projection 28.
  • the slide 22 projects into the opening 21 and is cushioned via the spring element 26 in such a way that it turns away from the spring element 26 on a shoulder or stop of the stop bar 20 is held. If the door 6 is closed, then the latching hook 3 is inserted into the opening 21 of the stop bar 20 against the pressure of the door seal, the latching bevel of the latching hook 3 pushing the slide 22 out of the opening 21 under tension of the spring element 26 until the spring element 26 Slider 22 engages behind the disengagement slope of the locking hook 3. The door 6 is then held in the closed position by the latching position of latching hook 3 and slide 22.
  • the front end face of the securing element 25 is designed as a slot.
  • Actuating receptacle 23 provided so that the securing element 25 can be rotated from the front of the stop bar 20 with a coin or a screwdriver.
  • a rotation through 90 ° is provided in the exemplary embodiment in order to change the setting of the securing element 25.
  • the control cam in the new rotational position is only a small distance from the axis of rotation of the securing element 25, so that, as the section according to FIG. 6 shows, the slide 22 with the spring element 26 can escape from the opening 21.
  • the locking hook 3 is no longer when inserted into the opening 21 of the stop bar 20 by the slide 22 held.
  • the door 6 is therefore not held in the closed position.
  • the pressure of the door seal sets the door 6 back so far after the release that the door contact is not actuated. Therefore, the tumble dryer cannot be put into operation.
  • the front end face of the securing element 25 can also be provided with actuating receptacles 24 specially designed for a tool, which at the same time serve as an indication of the position of the securing element 25.
  • the positions of the securing element 25 alternate in 90 ° rotation steps, so that the direction of rotation does not play a role in changing the setting.
  • the actuating receptacle 24 can be matched to a special tool, so that unauthorized commissioning of the tumble dryer can be prevented. Only the user can set the securing element 25 with the special tool so that the door is held in the closed position after closing and the clothes dryer can be put into operation.
  • a second exemplary embodiment of a stop bar 20 is shown, the latching hook 3 on the door 6 again being symmetrical and provided with snap-in and snap-out bevels.
  • the slide 22 is supported on the opening 21 facing away from the spring element 26 on a shoulder or stop 30 of the stop bar 20.
  • the spring element 26 is designed as a helical spring and pushed and guided on a bolt-shaped extension of the slide 22.
  • the approach is preferably integrally formed on the slide 22 and also guided in the shoulder or stop 30 of the stop bar 20 so that the coil spring can be supported on the slide 22 and the shoulder or stop 30.
  • the slide 22 Facing the opening 21, the slide 22 is extended with a frame-like extension 21 which is supported on a control cam 28 of a securing element 25 which is rotatably mounted outside the opening 21 in the stop bar 20.
  • the control curve of the control projection 28 is again designed with four positions offset by 90 °, the control curve being at the small distance from the axis of rotation of the securing element 25 in the position shown in FIG. 7. This has the consequence that the spring element 26 holds the slide 22 in the sprung working position, in which it protrudes into the opening 21 and can hold the inserted locking hook 3 in a locking position.
  • the control cam is at a large distance from the axis of rotation of the securing element 25, so that the slide 22 itself is adjusted over the molded extension 27 and moved out of the opening 21.
  • the locking connection between the slide 22 and the locking hook 3 can therefore no longer be produced when the door 6 is closed.
  • the opening of the frame-like extension 27 of the slide 22 is also rectangular. The longitudinal dimension is greater than the longitudinal dimension of the opening 21, so that the slide 22 does not protrude into the opening 21 with the edge facing the securing element 25.
  • the dimension of the opening of the extension 27 perpendicular to the longitudinal direction of the stop bar 20 is equal to or less than the assigned dimension of the opening 21, but larger than the thickness of the locking hook 3, so that the extension 27 the insertion of the locking hook 3 into the opening 21 of the stop bar 20 not disabled.
  • the slide 22 can be guided and held by guide strips 29 in the stop strip 20.
  • the approach 27 of the slide 20 holds the securing element 25 in the bore of the stop bar 20th
  • the invention is not restricted to the exemplary embodiments shown.
  • the suspension of the suspended working position the slide 20 can also be released in a different way by a securing element 25.
  • the slide 22 and the securing element 25 can also be designed, stored and adjusted differently. It is important for the additional child safety device of the door lock that the closed position of the door 6 is controlled, maintained or cannot be maintained by the safety element 225 and this depends on the position of the safety element 25.
