Description

Dishwasher and method for opening a door of a

dishwasher

The present invention relates to a dishwasher with a washing container for receiving items to be cleaned, a pivotable door, which in

closed position closes the washing container, and a locking arrangement, by which the door is locked in its closed position and which comprises at least one movably mounted locking element. The invention also relates to a method for opening a door of such a dishwasher. Dishwashers typically have a decorative plate attached to the door, or e.g. in the form of a furniture sheet, attached handles and / or recessed grips to open the door. However, this often causes the problem that the design of the handles or recessed grips does not match the design of the handles or recessed grips of other kitchen furniture fronts, which is aesthetically unsatisfactory. In addition, there is a certain trend in the field of kitchen furniture to handle-less

Furniture fronts, with the home appliance industry has barely followed this trend so far. One reason for this is certainly the problem of door opening.

From EP 1 935 313 A1 a dishwasher is known, whose door is provided with a decorative plate which is attached to the door by a fastening system.

The fastening system allows a relative movement between the plate and the door by pressure on the plate attached to the door. To capture the

Relative movement and to output a corresponding signal is a

Motion sensor provided. An actuator is designed to open a shutter mechanism of the door upon receipt of the signal.

From DE 10 2008 021 496 B4 a dishwasher with a movable door is known in which an opening mechanism is provided and in which a decorative plate is resiliently mounted on the door at the door. For detecting a force acting on the decorative panel, a sensor is provided, by means of which the opening drive can be triggered in order to move the door from a closed position to an at least partially open position. However, both of the aforementioned systems have the disadvantage that the opening mechanisms can only be used for dishwashers, in which the doors are covered by decorative panels. The opening mechanism is additionally influenced by the material and the thickness of the decorative panels. In addition, the design effort for implementation is relatively large.

The object of the invention is to provide a dishwasher, the door can be opened reliably regardless of the presence of a decorative plate or regardless of their material or thickness and with little design effort. Another object of the invention is to provide a method for easy and reliable opening of the door of a dishwasher

These objects are achieved by a dishwasher and a method having the features according to independent claims 1 and 10, respectively.

A dishwasher according to the invention comprises a rinsing container for receiving items to be cleaned, a pivotable door which closes the rinsing container in the closed position, and a locking arrangement, by means of which the door can be locked in its closed position and which comprises at least one movably mounted locking element. By one on the closed door in

Direction of the washing container acting force is caused by a movement of the at least one movably mounted locking element or a component operatively connected therewith. This movement is detected by means of a sensor system. In addition, an actuator is provided which unlocks the door depending on the detected movement and opens at least in columns.

Dishwashers typically include a latch assembly that holds the door in its closed position. Opening is only possible if the door was either manually unlocked before or a correspondingly large force in

Opening direction of the door was spent (pull-locks). Essentially due to the elastic properties of the usual way provided

Door seal can be the door of a dishwasher even in the closed state of the door by a force from the outside even slightly in the direction of Press rinse container. However, such movement of the door also results in the locked state of the door to a movement of movable elements of

Latch assembly. The evaluation of this movement according to the invention makes it possible to interpret a pressing against the door in a reliable and structurally simple manner as an opening requirement for the door.

The dishwashing machine according to the invention thus makes it possible to sense an opening request independently of the presence of a decorative plate. Of course, however, facing away from the washing on a closed position in the door

Exterior wall of the door also be attached to a decorative plate. As the opening request but in contrast to the aforementioned and known from the prior art

Dishwashers is sensed independent of a relative movement of the decorative panel to the door, the decorative panel can be fixed gap-free on the outer wall of the door without further design effort. Under a decorative plate is understood here any type of cover, which is fastened on the outer wall of the door facing away from the washing in the closed position.

Also, the decorative panel may be immovably fixed relative to the outer wall on the outer wall of the door, which also contributes to a simple structural design. Sensing an opening request according to the invention by evaluating the movement of a locking element of the locking arrangement does not require a grip element or a recessed grip on the door or on the decor panel attached thereto. Therefore, the door and / or the decorative plate can be handleless, that is, without handle elements or recessed grips, be designed. Are also control and display elements not on the visible in the closed state of the door front of the door, but arranged in the hidden upper or side door edge region, the front surface of the

Dishwasher free of any handle, control or display elements are designed. In this case, for example, it is also possible to use a handle-less decorative plate, e.g. in the form of a furniture sheet to attach to the door, which covers the outer wall of the door over its entire surface.

The locking arrangement and thus also the movable locking element whose movement as a size to be sensed to detect an opening desire Serves are usually at the top of the door of the dishwasher

arranged. In this area, the existing in the closed position of the door movement of the door is relatively large, as it is a long distance from the

Swivel axis of the door, which is usually located in the region of the lower end of the door has. Moreover, the locking arrangement is usually arranged approximately centrally with respect to the width direction of the dishwasher. This has the advantage that the pressure force to be exerted on the door to sense an opening desire is kept relatively low over the entire width of the door, so that the unlocking and opening mechanism always works reliably regardless of the specific location of the application of force.

According to one embodiment of the invention, a carrier element, e.g. in the form of a housing or a housing part, provided on which a

Entriegelungsaktuatorik and at least parts of the sensor system are arranged. The Entriegelungsaktuatorik represents that part of the actuator, which serves the door latch. Particularly preferred is the entire sensor system, which comprises at least one sensor and an associated control unit, on which

Carrier element arranged. The sensor system thus forms together with the

Entriegelungsaktuatorik a complete module, which can be installed quickly and inexpensively as an optional component of the dishwasher and in particular also be retrofitted.

The at least one sensor of the sensor system can be designed as a resistive or capacitive or inductive or optical or piezoelectric sensor. Ultimately, any sensor is suitable, which is capable of caused by a manual force on the door movement of the movable locking element, which depending on the specific configuration of the locking arrangement possibly in the range of less than 1 mm, in particular at a maximum of 80 μηη or even can lie at a maximum of 50 μηη, reliably detect. Specifically, the sensing of an opening request can be effected in that the control unit of the sensor system compares the detected movement with a predefinable threshold value and controls the actuator system when the threshold value is exceeded such that the door unlocks and opens at least in columns. Thus each will manually applied to the door or the decorative panel attached thereto force in the direction of the washing container, which leads within a predeterminable period of time to a predetermined movement of the movable locking element as opening desire detected, which then leads to unlock and open the door. The concrete position of the closed door relative to the body of the

Dishwasher is in addition to the concrete structural design also dependent on operating parameters and environmental conditions of

Dishwasher. Thus, the position becomes e.g. by the temperature inside the washing container as well as by the outside temperature in the environment of the

Dishwasher influenced. Likewise, the position may vary in

Dependence on the time interval to a preceding opening and / or closing operation. Aging effects, in particular with regard to the door seal, can also influence the concrete closing position of the door. In this respect, it is provided according to an embodiment of the invention, the threshold value for sensing an opening desire as a function of operating parameters and / or

Set ambient conditions of the dishwasher. In this way, the current framework conditions can be taken into account, so that a reliable sensing of an opening request is ensured in every situation. The necessary for the actual opening of the door part of the actuator, namely the

Opening actuator, can be largely or completely independent of the

Entriegelungsaktuatorik be realized. For example, the Öffnungsaktuatorik include one or more spring elements, which, for example, in the field of

Door hinges are arranged. However, the Öffnungsaktuatorik can also be designed such that it partially mitübernimmt the tasks of Entriegelungsaktuatorik partially. For example, an impact element, e.g. in the form of a plunger, conceivable which acts on the door. For a pull-lock, the functions "unlocking" and "opening" could thus be realized by a single actuator. In any case, it is advantageous, at least individual components of Entriegelungsaktuatorik for

Sharpen opening actuator and vice versa. It is conceivable, for example, to provide a common drive unit for both actuators. The above-explained and / or reproduced in the subclaims advantageous embodiments and refinements of the invention can - in addition to z. B. in cases of clear dependencies or incompatible alternatives - individually or in any combination with each other.

The invention and its advantageous embodiments and further developments and advantages thereof are explained in more detail below with reference to drawings. They show, in each case in a schematic outline sketch:

In the following figures, corresponding parts are the same

Provided with reference numerals. Only those components are provided with reference numerals and explained, which are necessary for the understanding of the invention.

FIG. 1 shows a side view of a dishwasher 1 according to the invention in the form of a household dishwasher. This has a washing compartment 2 for receiving items to be cleaned, which can be closed in the direction of a front side by means of a pivotable door 3, which in the illustrated embodiment, handleless, that is without handle elements or recessed grips executed. The door 3 is shown in Figure 1 by solid lines in its closed position in which it closes the washing compartment 2. In addition, the fully open position is the Door 3, in which the dishwasher 1 can be loaded with dishes, indicated by dashed lines. The door has a user facing

Outer wall 3-1 and the washing container 2 facing the inner wall 3-2. In the lower region of the washing container 2 surrounding the body 4 of the dishwasher 1, a hinge 5 is indicated, on which the door 3 is pivotally mounted.

In order to hold the door 3 in the closed position and to lock it and to prevent leakage of rinsing liquid, the dishwasher 1 in a locking portion 5, which may be arranged for example in the upper middle region of the door 3 and the body 4, a Locking arrangement on how they are in

The following is described by way of example.

In the context of the explanation of the basic functioning of the

Locking arrangement is first referred to Figures 2 and 3, which show a possible structure of the same.

The locking arrangement 6 comprises a frame element 7, in which a movable locking element 8 is guided or mounted, which is designed in the embodiment variant shown in the form of a striker. With the help of the frame member 7, which may be made of a plastic, for example, the locking element 8 on the body 4, in particular between the washing compartment 2 delimiting ceiling area and attached to the outside of the carcass 4 ceiling panel of the dishwasher 1, so that as a result a movement of the locking element 8 relative to the body 4 of the dishwasher 1 is possible.

Furthermore, the locking arrangement 6 comprises a force accumulator 9, which the

Locking member 8 is acted upon by a closing force with which it is movable from an open position, as shown in Figure 2, in a locking position, as shown in Figure 3. The open position is defined as the position in which an approach of the door 3 in a front region 10 of the

Locking arrangement 6 is possible, the locking element 8 so not yet with a corresponding retaining element 20 of the door 3 is engaged. By contrast, the locking position is defined as the position in which the locking element 8, For example, via the nose shown in the figures 1 1, with the holding member 20 is engaged and thereby locks the door 3 relative to the body 4.

The operation of the locking arrangement 6 is now the following: First, the locking element 8 is in the open position (Figure 2), wherein it is preferably in contact with a stop surface 12, which prevents premature movement into the locking position (Figure 3). Now, if the door 3 is closed by an operator, it is necessary that the locking element 8 is disengaged from the abutment surface 12. For this purpose, the locking element 8 preferably has a release element 13, which is shown in Figures 2 and 3 by way of example as a laterally projecting bolt. In this case, the door 3 should expediently a

corresponding, for example, wedge-shaped counter-element, which in contact with the release element 13, a movement of the front portion 10 of

Locking member 8 causes downward so that it can slide over the stop surface 12. As a release element 13 can of course also another

Construction to be used, the said movement of the

Locking element 8 causes. It is also conceivable, for example, a rotary latch, which undergoes a rotation upon contact with the door 3, wherein this rotation finally results in a movement of the locking element 8, so that this of the

Stop surface 12 is moved away.

Finally, if the locking element 8 is below the abutment surface 12, the already mentioned force accumulator 9 ensures that the locking element 8 is moved in the direction of its locking position. The energy storage device 9 may be formed, for example, as shown here as a spiral spring, which is on the one hand in the region of a rear portion 14 of the locking element 8 and the other at one

Supporting surface 15 of the frame member 7 is supported. As a result, on the

Locking element 8 exerted a force that pulls it toward the rear portion 14. Since the locking element 8 in its locking position with the

Holding member 20 of the door 3 is engaged, the door 3 is also drawn according to the body 4 and to a arranged between the body 4 and door 3 door seal, so that leakage of rinsing liquid and / or steam can be excluded. A tightening on the door 3 in its closed position would cause the nose 1 1 and thus also the locking element 8 is pulled against the force of the force accumulator 9 in the direction of its front portion 10. As soon as the locking element 8 has been moved far enough, finally, a movement of the front portion 10 upwards is possible, so that it comes out of engagement with the corresponding holding element 20 of the door 3. In order to promote said upward movement in the position shown in Figure 2, the frame member 1 can be equipped with corresponding guide surfaces which cooperate with corresponding mating surfaces of the locking element 8. Likewise, the nose 1 1 and / or the holding member 20 may have a corresponding shape, as shown in Figure 3, which causes said upward movement in contact with the door 3.

In order to enable a tightening on the door 3, however, it would be necessary to provide a handle element or a recessed grip on the door 3, but this is often the case

design technical or aesthetic reasons is undesirable. According to the invention, therefore, a force acting on the closed door 3 in the direction of the washing container 2 is to be interpreted as an opening request. In other words, therefore, a manual pressing on the door 3 should cause the door 3 to open. FIG. 3 shows the

Locking arrangement 6 with the door closed 3. The locking element 8 is therefore in its locking position, so that the hook 1 1 of the

Locking element 8 with the corresponding holding element 20 in the door in

Intervention is. The holding element 20 is designed as a recess - often referred to as a door recess 20 '- configured. Such a door well 20 'is often used in the form of a door well insert 21 shown in Figure 3 in the door 3 of the dishwasher 1. The holding member 20, e.g. in the form of the door recess 20 ', but may also be formed directly on the door 3. Will now on the door 3 and thus the

Door well insert 21 a force F exerted in the direction of the washing compartment 2, so first moves the door pan insert 21 so far in the direction of the washing container 2 to the outer wall 3-1 of the door 3 facing side surface 22 of the door panel 20 ', which in the illustrated embodiment is formed obliquely, comes into contact with the hook 1 1 of the locking element 8. From this point, a further action of the force F on the door 3 in addition to a movement of the door trough insert 21 also leads to a corresponding movement of the locking element 8. This movement is evaluated according to the invention in order to sense an opening request. For this purpose, a sensor system is provided, which has at least one sensor 30 for detecting the movement of the locking element 8 or a so in

Active compound standing component comprises. The sensor 30 can be used as a resistive sensor, e.g. in the form of a strain gauge, be executed. Likewise, however, it is also possible to use a capacitive, inductive, optical or piezoelectric sensor. A combination of several, even different sensors is conceivable. By way of example, in FIG. 3, two alternative installation locations for the sensor 30 are identified by an x and the reference numerals 30-1 and 30-2. A first installation location 30-1 lies in the area behind the locking element 8. The sensor 30 can then detect the movement of the locking element 8 caused by the force acting on the door 3 and thus the door trough insert 21 in the form of the approach of the locking element 8 to the sensor 30 , In addition to the immediate detection of the movement of the

Locking element 8, it is also conceivable, the movement of a with the

Locking element 8 operatively connected component, such. of

Türmuldeneinsatzes 21, to capture. An alternative second installation location 30-2 of the sensor 30 is therefore in the region of the door well insert 21. In addition to the two installation locations 30-1 and 30-2 illustrated, however, numerous other installation locations are conceivable. It is only decisive that the selected type of sensor and the selected installation location ensure reliable detection of the movement of the locking element 8 or a component operatively connected thereto, it being noted that the movement is in the range of less than 1 millimeter, in particular less than 80 microns or even less than 50 microns. The with the

Locking element 8 operatively connected component can also as

Additional part or intermediate element to be executed, which exclusively for the purpose of indirect detection of the movement of the locking element 8 with the

Locking element 8 is brought into operative connection. In this way, if necessary, a higher flexibility with regard to the installation location for the sensor 30 can be achieved. The component can also comprise several subcomponents. Furthermore, the sensor system has a control unit 31 (compare Figures 4 and 5), which compares the detected movement with a predetermined threshold and controls an actuator when the limit is exceeded such that the door unlocks and opens at least in columns. For this purpose, the actuator system has an unlocking actuator as well as an opening actuator which can be implemented separately from one another or at least with respect to subcomponents. An exemplary embodiment of a

Entriegelungsaktuatorik 32 is shown in Figures 4 and 5.

The Entriegelungsaktuatorik 32 has a drive unit 33, by means of which the locking element 8 is movable from the locking position against the closing force of the energy accumulator 9 in the open position. As a drive unit 33 is for this any drive in question, the corresponding movement of the locking element 8 from the locking position in the

Open position allows. Conceivable, for example, linear drives, electric drives, possibly also with gear, bimetals or similar responsive to temperature fluctuations components, etc.

As an example, in Figures 4 and 5, a solution is indicated, in which the

Drive unit 33 is formed by an electric drive 33 ', which is preferably connected independently of the frame member 7 with the body 4 of the dishwasher 1, so that at any time a corresponding retrofitting is possible.

A connecting element 34 in the form of a rotary arm 34 'is non-rotatably connected to a rotatable shaft 35 of the electric drive 33'. On the rotary arm 34 'spaced from the shaft 35, a driver 36 is rotatably mounted. The axis of rotation of the driver 36 is preferably perpendicular to the plane defined by the width direction and depth direction of the body 4 level. As an alternative to the rotary arm 34 ', the

Connecting element also otherwise, e.g. as a hub, be executed.

The operative connection between drive unit 33 and locking element 8 is realized by means of an intermediate member 37, which is formed in the example shown as a rocker arm 37 ', which is rotatably supported via a rotation axis 38. Also, the axis of rotation 38 of the rocker arm 37 'is preferably perpendicular to the plane defined by the width direction and depth direction of the body 4, so that the rocker arm 37' sweeps over a pivoting range in this positional plane. To a tilting movement of the rocker arm 37 'to cause a first leg 39 of the rocker arm 37' is guided in the driver 36, that is movable in the longitudinal direction of the first leg 39 in the

Carrier 36 stored.

If now the drive unit 33 is activated, the rotary arm 34 'executes a rotational movement, which results from the bearing of the first leg 39 of the rocker arm 37' in the driver 36 in a rotation of the rocker arm about the axis of rotation 38. In this case, the rocker arm 37 'from the position shown in Figure 4 in a position as shown in Figure 5, rotated. In this case, a corresponding engagement surface 40 of a second leg 41 of the rocker arm 37 'comes into contact with a contact surface 42 in the rear region 14 of the locking element 8 and thus causes a force transmission from the drive unit 33 via the intermediate member 37 to the locking element 8, which consequently causes a movement in the direction of the open position learns.

Finally, next to this, take place forward movement, d. H. in the direction of the front portion 10 to cause the upward movement in particular of the nose 1 1, which is ultimately necessary to bring the locking element 8 completely out of engagement with the corresponding holding member 20 of the door 3, different solutions are conceivable, which in the earlier application DE 10 201 1 007 538.0, the disclosure of which is to be fully integrated into the present application, are described in detail.

Due to the storage and guidance of the first leg 39 of the rocker arm 37 'in the driver 36 and the resulting continuous mobility of the

Kipphebels 37 'is no return element for the rocker arm 37' required. In addition, the illustrated embodiment according to Figures 4 and 5 is characterized by a particularly space-saving arrangement, which in particular results from the fact that the by the movement of the rotary arm 34 'spanned circle is fully utilized. Alternatively, the Entriegelungsaktuatonk 32 but also be configured elsewhere. Examples of this also emerge from the earlier application DE 10 201 1 007 538.0.

The opening actuator required for the actual opening of the door 3 can largely or completely independently of the Entriegelungsaktuatonk 32, for example in the form of be realized one or more spring elements, which are arranged for example in the region of the hinge 5. However, the Öffnungsaktuatorik can also, for example, as an impact element, for example in the form of a plunger, which acts on the door, be realized. It is advantageous to share at least individual components of the Entriegelungsaktuatonk 32, such as the drive unit 33 for the Öffnungsaktuatorik. The opening of the door 3 can be done in columns, completely or in any intermediate position.

The sensor 30 for detecting the movement of the locking element 8 can also in the embodiment shown in Figures 4 and 5 at various

Installation locations can be arranged. By way of example, in FIG. 4, two conceivable installation locations 30-3 and 30-4 are again identified by an x. A first installation location 30-3 lies in the region between the contact surface 42 in the rear region 14 of the locking element 8 and the engagement surface 40 of the second leg 41 of the rocker arm 37 '. The installation site thus corresponds to the installation location 30-1 according to FIG. 3, so that the sensor 30 can detect the movement of the locking element 8 caused by pressing on the door in the form of the approach of the locking element 8 to the sensor 30. An alternative second installation location 30-4 of the sensor 30 is in the area behind the second leg 41 of the rocker arm 37 ', which is in operative connection with the

Locking element is, so that its movement is suitable for sensing an opening desire.

In addition to the sensor 30, the sensor system comprises a control unit 31, which is indicated schematically in Figure 4. The control unit 31 compares the detected by the sensor 30 movement with a predetermined threshold and contributes

Exceeding the limit, the actuator, that is, the unlocking and the Öffnungsaktuatorik, such that the door is unlocked and opened at least in columns. In this case, the threshold value is preferably determined as a function of operating parameters and / or ambient conditions of the dishwasher in order to take account of the current operating situation. The Entriegelungsaktuatonk 32 can be arranged together with the sensor system, that is the sensor 30 and the control unit 31 on a common support member 46, for example in the form of a housing, so that it can be installed as a complete module and in particular also retrofitted. Figure 5 shows next to the latch assembly 6 and the Entriegelungsaktuatorik 32 and a possible positioning of the same. Thus, it is conceivable to arrange the frame element 7 on the upper side of the already mentioned body 4 of the dishwasher 1, wherein this can have an opening 47 in its region facing the door 3, through which a part of the locking element 8, for. B. the nose 1 1, at least in the locking position can protrude to the with

corresponding holding element 20, for example in the form of the door recess 20 ', to engage. In this context, it should be noted that the door 3 in Figure 5 is still a gap open. To activate the locking mechanism, it would therefore have to be moved further in the direction of the body 4 until the holding element 20 is located under the nose 11 of the locking element 8. On the outer wall 3-2 of the door 3 shown in Figure 5 is a decorative plate 48, which may be executed in particular without handles, without gaps and fixed relative to the outer wall 3-2 immovably. The decorative plate 48 can cover the outer wall 3-2 of the door over the entire surface.

Incidentally, the invention is not limited to the illustrated embodiments. Rather, all combinations of the individual features described, as shown or described in the claims, the description and the figures and as far as a corresponding combination is technically possible or seems reasonable, the subject of the invention.

In the illustrated and described embodiments of the invention, the locking assembly 6 is respectively attached to the body 4 of the dishwasher and cooperates with a arranged on the door 3 corresponding holding element 20 together. Alternatively, the locking assembly 6 but also be attached to the door 3 and accordingly cooperate with a holding element 3, which is arranged on the body 4 and which is embodied for example in the form of a rotary latch, which in a force on the door 3 in the direction of Rinse container undergoes a rotation. This rotational movement can then be detected in turn depending on the door 3 unlocked and opened. LIST OF REFERENCE NUMBERS
