Definitions
- the present invention relates to a household appliance, in particular a dishwasher.
- a household appliance in particular a dishwasher.
- a conventional dishwasher such as a dishwasher with a pull-lock
- a certain amount of force on the part of the operator is connected, which is sometimes perceived as uncomfortable.
- An object of the present invention is to provide a household appliance which is equipped with a particularly cost-effective mechanism for opening the door. Therefore, a household appliance, in particular a dishwasher, is provided with a door, an actuator, in particular a thermoactuator, for opening or unlocking the door and a device. The device is configured to decouple closing or locking of the door from the actuator.
- a “thermoactuator” in the present case is an actuator in which a movement results as a function of a temperature change.
- “Movement” includes, for example, moving a working element, eg a working piston, between a starting position and an opening position, wherein the movement in the open position causes the door to open or unlock.
- the temperature change can be effected, for example, electrically, which can be easily implemented in terms of control engineering.
- Thermo-actuators usually comprise a wax (for example, oil, wax, hard paraffin or metal) caused by a change in temperature undergoes a phase transition and thus a significant volume change, resulting in a movement from the home position to the open position. The distance traveled is usually proportional to the volume change of the wax. If the expansion material cools down again, the working element, in particular the working piston, is typically pushed back by a spring into the corresponding housing of the thermal actuator and in this way is moved back into its starting position. Examples of such thermoactuators are wax motors, bimetals or shape memory alloys (memory metals).
- Thermoactuators in particular the mentioned wax engines, are characterized by the fact that they are particularly cost-effective.
- thermal actuators typically have the property that they are capable of only relatively slow actuation.
- the return movement of the working element from the open position to the starting position takes a relatively long period of several seconds to a few minutes to complete.
- the wax of the wax motor can be heated relatively quickly by means of an electrical heating device so that a relatively fast movement of the working piston relative to the return movement can be achieved from the starting position to the opening position due to the expanding wax.
- the cooling of the wax takes place more slowly than the heating, so that the return movement of the working piston from the opening position to the starting position takes place correspondingly slower.
- thermoactuator can be used to easily open or unlock the door, especially when the speed of movement of the actuator from the starting position to the opening position for the desired function is not critical, such as at a desired opening or unlocking the door at the end a drying program of a dishwasher.
- the thermoactuator itself in particular the working element itself, prevents such closing or closing from the opening position to the starting position due to the only slow movement speed of the working element, in particular working piston. unless additional measures are envisaged.
- thermoactuator whose speed of movement during the return movement of the working element from the opening position to the starting position falls below a predefinable minimum speed, or in other words, at each Actuator in which the return movement exceeds a predefinable period of time.
- a delayed return movement can be due to the system, as in the case of a thermoactuator, but can also result from a special arrangement, for example an electric motor with a complicated downstream gear mechanism.
- a corresponding additional measure is to decouple the closing or locking of the door from the actuator, in particular thermoactuator.
- This kinematic decoupling causes the door can be closed or locked, although the working element, in particular the working piston, at least partially extended due to its slow movement speed in the direction from the open position to the starting position. Closing or locking the door immediately after opening or unlocking the door is thus possible.
- the application of the invention is particularly useful if the return movement of the working element from the open position to the starting position lasts at least one second, in particular at least five seconds. If, in fact, the door can not be closed again for such a period of time, this represents a condition restricting the operation of the household appliance, which is perceived as disturbing or at least undesirable by an operator.
- opening / closing means a movement of the door to release (open) or close (close) access to a room behind the door.
- Unlocking / locking the door means an actuation of a locking element which releases an opening of the door (unlocking) or blocking such an opening (locking).
- the opening and unlocking can also take place simultaneously, just as the closing and locking can take place simultaneously. This is the case, for example, with a door lock in which the unlocking of the door with an opening thereof and / or the locking of the door associated with a closing thereof.
- the device is designed to couple the actuator with the door for opening the same or with a door lock for unlocking the door.
- the coupling creates a kinematic operative connection between the actuator and the door or the door lock. This kinematic operative connection is then through the decoupling is lifted to close or lock the door immediately after opening or unlocking the same.
- the device has a first and a second actuating element, which can be brought into contact with one another for coupling and for decoupling.
- the first actuator acts in a first direction against the second actuator while in abutment with each other. If the first actuating element is moved in a second direction substantially perpendicular to the first direction, then the first and second actuating element are out of engagement.
- the first actuating element may be formed, for example, as a plunger.
- the second actuating element can be designed, for example, as a lever.
- the first and second actuating element are each adjustable between a first and second position, wherein the first layer corresponds to a closed or locked state of the door and the second layer each corresponding to an open or unlocked state of the door, wherein the first and second actuating element, if these are each in their second position, can be brought out of abutment for the decoupling, whereby a return part of the second actuating element is released from its second position in its position.
- the first and second actuating element are thus provided in such a way that they move partly on the same path (first and second actuating element in contact) and partly on different tracks (first and second actuating element apart from the system). Thereby, the rear portion of the second operating member can be easily accomplished independently of a movement of the first operating member.
- the disengagement comprises a displacement of the first actuating element transversely to the feed axis of the actuator.
- the feed axis means the axis along which the working element, in particular the working piston, of the actuator is movable.
- the parallels and the perpendicular from 0 to 45 °, preferably 0 to 20 °, more preferably 0 to 10 ° or even more preferably 0 to 5 °.
- the device has a spring for the displacement of the actuating element.
- a different kind of actuator such as a permanent magnet or solenoid may be used.
- the first actuating element has a bevel against which the spring acts at least indirectly.
- “Indirectly” here means indirectly and directly. “Indirect” means that the spring can act on the first actuating element, for example, by means of an intermediate plunger. However, a direct action of the spring - without intermediate element - on the first actuator is possible.
- the slope causes the spring to be increasingly tensioned as the first actuator is moved along the feed axis. In addition, the slope causes the force applied by the spring to have a component in the direction transverse to the feed axis.
- the first actuating element for the insertion and dislocation is movably provided on a closed path.
- the closed path may be, for example, circular, oval, rectangular, square or oblong-shaped.
- the device has a link, which cooperates with a link element of the first actuating element to define the closed path.
- the backdrop may be formed, for example, in the form of a slot-shaped elevation.
- the link element may be formed, for example in the form of a pin, which is moved along the outer contour of the slot-shaped elevation.
- the closed path has a first and a second path section, along which the first actuating element can be adjusted by means of the actuator, in particular thermoactuator.
- the first and second track sections are preferably formed parallel to one another.
- the first web section typically corresponds to the extension of the working element, e.g. in the form of a working piston, the actuator, while the second path section corresponds to the retraction of the working piston.
- the closed track has a third and a fourth track section, which connect the first and second track sections to one another and along which the first actuating element can be adjusted by means of one or more springs.
- the third and fourth track sections may each be semicircular.
- the third track section preferably connects the first and second track sections at their respective one ends, while the fourth track section preferably connects the first and second track sections at their respective other ends.
- the first actuating element is adjustable by means of the actuator along the first path section from the first in its second position in the feed direction of the actuator, wherein the first actuating element at least indirectly comes into contact with a first spring and the second actuating element and thereby the compressed first spring and the second actuator between its first and second position adjusted.
- the direction from the starting position of the working element, eg of the working piston, in its opening position preferably means "in the feed direction of the thermoactuator", preferably the direction along which expands the expansion of the thermal actuator.
- the actuator, in particular the thermal actuator, or its working piston has a relatively high movement speed in comparison to the return direction (counter to the feed direction). The door can thereby be opened or unlocked quickly, for example within 45 to 60 seconds.
- the first spring adjusts the first actuating element, if this is in its second position, along the third path section in the transverse direction to the feed axis from its second position to a third position, wherein the first actuating element comes out of engagement with the second actuating element.
- the first actuating element is adjustable by means of the actuator along the second path section from its third position into a fourth position counter to the feed direction, wherein the first actuating element at least indirectly comes into contact with a spring and thereby compresses the second spring.
- Contrary to the feed direction means a movement along the direction of the
- Opening position to the starting position of the working element is the direction along which the expansion material of the thermal actuator typically contracts, so that the corresponding speed of movement of the thermal actuator or the working piston thereof is low.
- the second spring displaces the first actuating element, when this is in its fourth position, along the fourth track section from its fourth position into the first position counter to the transverse direction. This results in a simple way, the closed path along which the first actuator is moved.
- the device has a stop against which the first spring abuts when the first actuating element is in its third position.
- the stop prevents the first spring from counteracting the second spring as the second spring moves the first actuating member along the fourth track portion.
- the first actuating element is mounted transversely to the feed direction movable on a working piston of the actuator.
- the working piston may have an engagement element which engages in a corresponding receiving element in the actuating element displaceable.

- the second actuating element is reset by means of the return spring.
- the second actuating element and optionally associated with this, further actuating elements are positioned such that the door can be easily closed or locked.
- the first and second actuation elements for bringing in place have mutually corresponding bevels.
- the first spring acts by means of a plunger on the first actuating element, which has a slope which corresponds to the slope of the first actuating element.
- the springs in particular the first and / or second spring, may be formed as compression springs, in particular spiral compression springs.
- the springs may be formed as leaf springs.
- the second actuating element is designed as a reversing lever. As a result, the device takes up little space.
- the second actuating element can also be designed as an eccentric.
- the second actuating element acts on a door-opening ram or a locking element of the door lock.
- a "door-open pestle” is a pestle that is moved substantially perpendicular to the door so as to push it in.
- a “door-latch locking element” is one such element which engages a recess in the door or in a door-opening-bounding frame of a housing Domestic appliance engages to lock the door, or can be disengaged with this recess to unlock the door and thus release it for opening.
- the door lock on a striker and a lever is by means of the actuator, in particular Thermoaktua- sector, from a locking position in which it engages positively in the door, adjustable against a force acting in the closing direction of the door spring in an unlocked position in which he releases the door for opening the same and against a return part is positively secured by the spring.
- the lever releases the positive lock, which causes the spring to move the striker to the locking position and pull the door in the closing direction.
- This type of door lock can also be referred to as a "pull-lock”.
- the door is formed without handles.
- the actuator according to the invention in particular thermoactuator, causes any opening of the door.
- the door is formed with a handle or a recessed grip.
- the actuator causes the opening of the door only when it is provided by the sequence program of the household appliance, for example, the washing program of a dishwasher.

- the device 1 1 has a first, stationary carrier part 28, on which the housing 22 is attached.
- a coil 25 is provided, which heats the wax 23 as soon as the control device 17 (see FIG. 1) supplies the coil 25 with current.
- the wax 23 then expands relatively quickly, wherein the working piston 24 is extended along the feed axis 26 in the feed direction V.
- the thermo-actuator 6 may have a spring, not shown.
- the working piston 24 is along the feed axis 26 in positive connection with a first actuating element in the form of an actuator tappet 27th
- FIG. 3 shows the actuator ram 27 in a perspective view.
- the actuator ram 27 has a T-slot 31, into which the working piston 24 at its free end, which is formed in the form of a Ts (not shown), engages positively along the feed axis 26 and along a transverse axis 32 transversely to the feed direction 26.
- the actuator ram 27 has a link element in the form of a pin 33.
- the pin 33 extends perpendicular to the plane defined by the feed axis 26 and the transverse axis 32 level E.
- the device 1 1 furthermore has a link in the form of a slot-shaped elevation 34.
- the elevation 34 is formed on a second, stationary carrier part 29 of the device 11.
- the support member 29 is shown in Figure 2 transparent.
- the actuator ram 27 or the pin 33 is guided in a manner described in more detail below on a closed path 35 (see FIG. 10) around the elevation 34 along its outer contour.
- the device 1 1 further comprises a first spring plunger 36, which is biased by a first spring 37 in the form of a helical compression spring in the transverse direction Q along the transverse axis 32.
- the first spring 37 is supported on the one hand on the first support member 28 and on the other hand on the first spring plunger 36 from.
- the spring plunger 36 has a bevel 41, which corresponds to a bevel 42 (see FIG. 3) of the actuator pusher 27, ie, the slopes 41, 42 have the same pitch and face each other.
- the first spring pusher 36 bears against a stop 40 in the transverse direction Q.
- the actuator plunger 27 and the first spring plunger 36 in the first position L1 of the actuator pusher 27 are spaced from each other by a gap.
- the working piston 24 displaces the actuator plunger 27 from its first position L1 along a path section 43 (see FIG. 10) in the feed direction V, whereby the actuator plunger 27 is in abutment with the bevel 41 of FIG first spring plunger 36 passes and thereafter the first spring plunger 36 against the transverse direction Q shifts and thereby compresses the first spring 37.
- An adjustment of the actuator pusher 27 in the transverse direction Q is prevented by the pin 33 in cooperation with the elevation 34.
- the actuator ram 27 comes into abutment with a second actuating element of the device 11 in the form of a deflection lever 44.
- the deflection lever 44 is initially located in its first position L1.
- the deflection lever 44 extends in its first position L1 along the transverse axis 32. "Along" in the present case comprises co-linear and parallel, unless indicated otherwise
- the deflection lever 44 has a first and a second end 45, 46 and is located between the Ends 45, 46 are pivotally mounted on the second carrier part 29 at an articulation point 47.
- the first end 45 comprises a bevel 51, which preferably has the same pitch as the slopes 41, 42.
- the bevel 42 of the actuator pusher 27 acts against the bevel 51 of the deflection lever 44, as a result of which the deflection lever 44 pivots out of its first position L1 into its second position L2 (see FIG. 6). Seen in Figure 2, the lever pivots thus clockwise about the pivot point 47. This finally also enters the actuator plunger 27 in its second position L2, as shown in Figure 10.
- the second end 46 of the reversing lever 1 1 is formed with an example semi-circular backdrop, which acts on an example T-shaped end 54 of a plunger 53.
- the plunger 53 passes through the first support part 28.
- a return spring 55 is arranged in the form of a helical compression spring. As soon as the deflection lever 44 actuates the tappet 53 counter to the feed direction V, the return spring 55 is compressed.
- FIG. 5 shows a section V-V on FIG. 4.
- the plunger 53 engages against the feed direction V positively a U-shaped bracket 56 which engages behind a pressure plate 61 at its free ends 57.
- an overload spring 62 is arranged in the form of a spiral compression spring, which may be provided with a bias of, for example, 50 Newton.
- the deflection lever 44 thus acts on the pressure plate 61 by means of the plunger 53 and the overload spring 62.
- the initially mentioned locking element 13 of the door lock 7 is presently designed as a striker.
- the striker 13 comprises two legs 63, which engage behind a spring 64 at its one end 65.
- the spring 64 is designed as a spiral compression spring.
- the spring 64 is supported on a housing 67 of the door lock 7.
- An upper part of the housing 67 is not shown in Figure 5 to release the view of the underlying components.
- the striker 13 has opposite to the legs 63 a hook 71 which extends in a direction perpendicular to the plane E.
- FIG. 4 shows a section IV-IV from FIG. 2.
- the hook 71 engages in its locking position in the recess 14 (see Figure 1). If now the deflection lever 44 acts on the legs 63 by means of the pressure plate 61, the striker 13 is actuated from its locking position (see FIG. 5) into its unlocking position (see FIG. 7). The hook 71 is moved on the one hand against the feed direction V and on the other hand in a direction R perpendicular to the plane E. The movement in the direction R is accomplished by the door lock 7 having a step 72. In the unlocked position (shown in dashed lines in Figure 4) of the Striker 13, the hook 71 locks in a form-fitting manner behind the step 72. The unlocking position of the striker 13 is also shown in FIG.
- the recess 14 is released in the unlocked position of the striker 13, so that the door 3 can be opened manually by the operator.
- the door 3 can also be automatically opened by a further device of the dishwasher 1.
- a further device of the dishwasher 1 is not shown in detail in the figures, it can be easily realized on the basis of the same principle of operation as shown above.
- the pressure plate 61 would not act on the door lock 7, but on a door-opening plunger 73, which is shown by way of example in FIG.
- the door opening plunger 73 would push the unlocked door 3 from its closed position to the open position.
- a differently functioning device for opening the door 3 could be used.
- FIG. 6 shows the view from FIG. 2, wherein the actuator pusher 27 and the deflecting lever 44 are each in their second position L2.
- the second layer L2 now lacks the support of the pin 33 in the transverse direction Q, so that the first spring plunger 36 presses the actuator pusher 27 in the transverse direction Q from the second ply along a semicircular track portion 74 into a third ply L3 (see FIG. 8) , As soon as the actuator pusher 27 reaches its position L3, or shortly before, the first spring plunger 36 abuts against the stop 40. As the actuator pusher 27 moves from its second position L2, see FIG. 6, into its third position L3, see FIG.
- the first spring tappet 36, the first spring 37 and the stop 40 can be dispensed with.
- the bevel 51 of the reversing lever 44 acts on the slope 42 of the Aktuatorst formulateels 27 that the Aktuatorstshuel 27 is moved to the end of its movement in the feed direction V in the third layer L3.
- the actuator tappet 27 is pulled along a web section 77 (see FIG. 10) by means of the working piston 24 of the thermal actuator 6 slowly counter to the feed direction V and thereby moved into its fourth position L4.
- the track section 77 is provided parallel to the track section 43. Therefore, the movement along the path portion 77 is slower than the opposite movement along the path portion 43 because the wax 23 cools and contracts more slowly as it heats and expands.
- the device 1 1 further comprises a second spring tappet 81 which is supported on the second carrier part 29 via a second spring 82 in the form of a helical compression spring.
- a second spring tappet 81 which is supported on the second carrier part 29 via a second spring 82 in the form of a helical compression spring.
- the second spring plunger 81 presses the actuator plunger 27 by means of the slope 83 against the transverse direction Q along a track section 84 (see Figure 10) back into its first position L1.
- the second spring tappet 81 and the second spring 37 can be dispensed with.
- a bevel, not shown, arranged on the second carrier part 29 acts on the actuator tappet 27 in such a way that the actuator torrent 27 is moved towards the end of its movement counter to the feed direction V in the first position L1.
- Figure 1 1 shows the view of Figure 5 and illustrates an integrated overload protection.
- a child safety device is activated or an opening of the door 3 is otherwise prevented, for example, if a heavy object is in front of the door 3, the striker 13 can not move from its locking position shown in Figure 1 1, as in the present construction also always requires a certain opening movement of the door 3.
- the overload spring 62 is provided. This is compressed when the striker 13 can not move from its locking position to its unlocked position and at the same time the lever 44 is actuated by means of the Aktuatorst Formulaels 27 in its second position L2.
- control device 17 may be configured to unlock the door 3 during or after a drying program of the dishwasher 1 by correspondingly activating the thermoactuator 6.
- the touch sensor 16 is optional in this embodiment.
- thermoactuator by another actuator which, in particular, similar to a thermoactuator, only allows a slow return movement of the working element.
