Definitions
- the invention relates to a door opening device for a domestic appliance, which is designed for automatically opening a door of the domestic appliance, and having a drive motor which is mechanically coupled via an actuating device with a door hook. Furthermore, the invention relates to a domestic appliance, in particular an oven, with such a door opening device.
- Domestic appliance door opening devices such as ovens, microwave ovens, freezers, refrigerators or the like are known in a variety of ways.
- the doors are provided in this context for closing a cooking chamber or other storage space.
- doors which have on a front panel at the front at least one handle element which can be gripped by a user and manually operated, so that the door can be opened.
- Such grip elements are usually over to the front, so that they need a place and on the other hand, a user can push it.
- a relatively high application of force be expended in order to ensure the opening can.
- automatic door opening devices are provided on door devices for opening the door.
- the door is unlocked by pressing an actuating element or an opening button and is automatically opened or pops up.
- the opening is only possible by a service staff or customer service.
- no further explicit grip element is provided any longer. The handling is therefore user-unfriendly. For complete opening, therefore, the user must explicitly the front panel or the usual Do not touch areas of the door that are not primarily gripped and open the door completely. As a result, the door is contaminated by finger marks and the like and must therefore also often wiped and cleaned due to hygienic conditions.
- the door opening device has a drive motor, which is mechanically coupled via an actuating device of the door opening device with a door hook.
- the drive motor is coupled to a cam element of the actuating device, which has a helical cam track, against which a transmission element of the actuating device, which is coupled to the door hook and with which the movement of the cam member is transferable to the door hook.
- this motion conversion can be particularly smooth and smooth, so that even here unwanted movements can be prevented.
- the occurrence of high torques or force effects on the components can be avoided when opening, so that the wear of the Door opening device can be significantly reduced.
- this helical or tortuous path of the cam a particularly precise, metered and accurate motion control.
- the cam member is rotatable by the drive motor about its longitudinal axis and the rotational movement is converted by the helical cam track in a linear movement, through which the door hook for opening the door is linearly movable.
- the linear motion guide of the door hook allows a more robust and much freer opening possibility compared to a direct action on a catch of the door opening device. Jamming, spreading or undesired twisting can be prevented and locking of the door opening can be avoided.
- the rotational position of the cam element can be detected by an electronic switch.
- the motion control can be made even more precise with regard to the precise control.
- the cam member has a first rotational position interval.
- a position of the cam member is detected which allows the door to be completely closed. Since the cam member is coupled to the motor, thereby a position of the motor is detected, in which he has virtually reached its zero position.
- the engine is so, in particular after opening the door, as long as turned back until it has reached its zero position again, then at some point subsequently to close the open door completely manually again.
- high safety requirements are taken into account, since the engine and thus also the cam element do not remain in an undesired position in which a complete closing of the door would no longer be possible.
- this position would be just that of a user can not be easily recognized whether the door is completely closed or not, then could safety-critical conditions, for example, in a pyrolysis operation a baking oven occur. This is avoided by this design.
- a turning back of the motor and the cam member from the end position to the zero position or basic position takes place in such a way that a rotation continues in the direction in which the cam member has been moved from the zero position to the end position.
- the motor shaft is always rotated in one direction of rotation.
- the driving of the motor by the control unit can be achieved much easier and thereby with less effort and less error rate.
- an elevation is formed on an outer side of the cam element, which can be detected by an electronic switch for detecting the rotational position of the cam element.
- the cam member has a second rotational position interval.
- this second rotational position interval extends from the first rotational intermediate position to an end position.
- the length of the cam path encompassed by the second rotational position interval is substantially longer, in particular by a multiple, such as the length of the cam track encompassed by the first rotational position interval.
- the joined lengths of the rotational position intervals of the helical cam track make a full revolution about the longitudinal axis of the cam member.
- the possibility of rotation of the cam member about its axis of rotation therefore preferably corresponds to a single full revolution.
- the transmission element comprises a ball bearing.
- a longitudinal ball bearing is arranged between a motor carrier and the cam member.
- the door hook is arranged on the door and the other components of the door opening device are on the household appliance itself and not on the door arranged.
- the components not arranged on the door are arranged on a lower closure of the household appliance for opening and closing the door.
- the door opening device operates to drive the drive motor through the control unit, and the cam or cam element coupled to the drive shaft of the motor rotates accordingly.
- the helical cam track and a transmission element contacted with it, in particular a ball bearing also rotate along this helical cam track.
- This ball bearing is attached to a plunger that presses directly on the door hook, wherein the plunger moves in the housing of the door opening device.
- the drive motor can be stopped quickly by being closed for a short time. This allows a good cam position adjustment, as the system responds very fast and has virtually no caster.
- a very fast deactivation can be achieved, for example, if the door is blocked by, for example, being locked or a person is leaning against it.
- the electrical supply of the motor may be limited or the current in the motor may be limited, for example, by a series resistor. Damage to the engine can be prevented and a quick shutdown can be made possible at any time.
- a door device for a household appliance comprises a door with a first vertical longitudinal side, to which preferably at least one stop element for pivoting the door can be attached parallel to the longitudinal side.
- the door comprises a second longitudinal longitudinal side opposite the first longitudinal side and an upper side extending between the longitudinal sides.
- the door device further includes a door opening device for automatically opening the door. It is provided that on the second longitudinal side of a handle member and / or on the upper side a handle member is formed, wherein the door has at least one recognition sensor, which is designed to detect a finger in a detection area around or on the or a handle member, and a control unit through the Door device is formed, which is formed depending on the information of the detection sensor for controlling the door opening device.
- a door device in which the door is designed in particular for lateral abutment, so that the door can be moved about a vertical longitudinal axis for opening and closing.
- the handle element is not mounted on the front side of the door in a very special positioning, but in quasi space-minimized and space-saving design on the second vertical longitudinal side and / or on the top. Since the door has a certain thickness, this second longitudinal side and the thickness associated therewith are suitable for receiving the gripping element, so that in this respect the thickness of the door does not change due to the gripping element.
- the long side therefore represents the area that results from the thickness of the door and extends from the front surface to the rear.
- this special positioning of the handle element on the longitudinal side can also prevent persons from hitting it, as is the case with handle elements which rise from the front side or the like.
- this specific position of the handle element is also a very user-friendly attachment, which leads the user virtually intuitively to the right place, especially in view of the already intended and intuitive opening and gripping the door on the right side.
- a gripping member for gripping with the fingers By explicitly forming a gripping member for gripping with the fingers, a configuration can also be provided in which unwanted attacking or slipping on other parts of the door with the fingers or the hand can be avoided, so that their contamination by the human hand can be prevented.
- a very ergonomic, adapted gripping possibility can be created by this explicit gripping element, which prevents slippage or the like, so that in this respect a user-friendly design for safe further opening and moving the door is ensured by a user after the automatic opening.
- at least one detection sensor is provided by which very quickly and promptly touching, grasping or at least in a nearby environment contact finger is detected to the handle element detected, so that an opening request is detected very quickly and early by the user and thus Also, the door opening device can be controlled much faster. The reaction time of the automatic door opening device can thereby be significantly reduced and reduced to an opening duration of less than 0.5 seconds.
- the grip element is formed as a stable part, which is designed in one piece.
- the grip element is stationary and thus not relatively movable to the door on the second longitudinal side and / or the top is arranged. It is therefore not intended that the handle element sets by a relative mobility to the door a certain opening mechanism in motion.
- the grip element thus serves only for gripping.
- a slot is formed on the second longitudinal side and / or the top of the door, in which the grip element is arranged.
- the gripping element is a particularly rectilinear strip which has an engagement region, in particular a corner-free groove corresponding to a recessed grip.
- a particularly ergonomic design that allows particularly easy to intervene with the fingers and manually open the door by little effort by the automatic opening.
- slipping and due to the corner-free design a hurting or snagging can be avoided.
- Not least can be formed by such a configuration already by a relatively shallow well sufficient grip area.
- a gutter leg facing a door front is designed longer than a gutter leg facing away from the door front.
- the legs or walls which is asymmetrical with regard to the trough, it is also possible here to take into account the most precise and stable holding possible. This allows for a larger area, with which one can get into the engagement area with the fingers, so that here too the accessibility to the engagement area is improved.
- the space depth on the side facing away from the door front can also be reduced, so that undesired stops on other components of the domestic appliance can be avoided.
- the handle element is arranged on the front side of the door behind a front panel of the door and covered by this.
- This is a special one protected arrangement, so that it can be avoided bumping and beyond unwanted wear or damage to the handle member can be avoided.
- Last but not least, this also allows high quality and design requirements to be taken into account, since the handle element can not be viewed when viewed from the front.
- the at least one detection sensor is a capacitive sensor.
- at least one electrode of the capacitive sensor is arranged in the door behind the grip element, in particular on the grip element behind an engagement region.
- a particularly accurate and particularly sensitive detection can be made possible.
- this specific local positioning of the electrode also a very protected and low-wear position. Not least can be made possible by this position even with a non-destructive detachable attachment of the handle member on the longitudinal side easy accessibility to the electrode for replacement or maintenance purposes.
- the grip element is formed at least in the region of the detection sensor of an electrically non-conductive material.
- the detection sensor may also be an inductive sensor or a microswitch.
- the automatic door opening device is designed with a child safety device. This is a particular advantage since it can prevent unwanted automatic opening of the door when grasping the handle element by a child.
- household appliances such as ovens or the like, which have relatively high temperatures during operation in the oven, which is closed with the door, thus a high security potential for children can be created.
- the door has an operating device, which is formed on a front panel of the door.
- an operating device which is formed on a front panel of the door.
- the child-safety device can be activated and deactivated electronically controlled by the control unit via the operating device.
- the operating device may have a display device, through which a wide variety of information can be presented to the user.
- the display unit of the operating device is also integrated in the door and in particular formed on the front panel, the visibility is particularly large for a user.
- the display of an activated or deactivated child safety device can thus be detected quickly and reliably by an adult.
- the door opening device can also be actuated via the operating device.
- the door opening device can also be actuated via the operating device.
- the activation of the door opening device, in particular a motor, by the control unit depends on detecting an operating state of the domestic appliance, in particular in a non-activated pyrolysis of the oven, and / or an electronically detected detection of a locking position of a cam member of a drive device of the door opening device and / or a closed door.
- the safety precautions can be increased with regard to an undesirable opening of the door.
- the door can also be opened manually at any time. As a result, a safe opening can be made possible even in the event of a power failure, and safety-critical conditions can be avoided.
- the control unit of the door device is designed accordingly and the individually set by a user configuration can be stored in it until it is possibly changed again.
- the door opening device of the door device has a door hook, which is arranged on the door, and which can be unlocked by means of a separately arranged for door drive device of the door opening device linearly actuated and with a drive device arranged rotary latch to open the door.
- the linear operation of the door hook opening can be done very reliable and without jamming or spreading. Since the catch is more complex in terms of its movement, namely performs a linear and a rotary movement, the action on the catch in the door opening would be more complex. By acting on the door hook and its linear movement, the error rate of the automatic door opening device can be significantly reduced.
- the invention relates to a domestic appliance, in particular an oven with a door opening device according to the invention or an advantageous embodiment thereof.
- Advantageous embodiments of the door opening device according to the invention are to be regarded as advantageous embodiments of the domestic appliance.

- the door includes a top 41. It can be provided that a further additional gripping element is arranged on this upper side 41 or that optionally the gripping element 9 is arranged on this upper side 41 and not on the longitudinal side 8.
- the door 6 also has a front panel 10, wherein on a front surface 1 1 of the front panel 10, an operating device 12 is formed.
- the operating device 12 comprises a display unit 13 as well as control elements 14 and 15 shown only in the form, position and number as an example. The operating device 12 and the grip element 9 are thus integrated in the door 6.
- the handle member 9 is shown in a perspective view. It is an integrally formed straight-line rail, which has an engagement region 16. This is designed as a corner-free recessed grip or groove, wherein parallel to each other groove legs 17 and 18 limit the recessed grip or the engagement portion 16.
- the handle member 9 is formed asymmetrically, since the front plate 10 facing gutter leg 18 is longer or further extends forward than the front plate 10 facing away gutter legs 17th
- Fig. 3 is a schematic representation of a section along the section line III / III in Fig. 1 is shown. It can be seen that the grip element 9 is integrated in a slot 19 of the door 6. The grip element 9 is thus virtually integrated into the door 6 and formed recessed. At least one electrode 20 of a capacitive sensor, which is a recognition sensor, is formed on the rear side of the grip element 9. By means of the recognition sensor it is detected whether a finger 21 extends into a detection area 22, which is exemplarily delimited by the dashed line, and / or whether the finger 21, As shown in Fig. 3, the grip member 9 touches.
- the electrodes 20 may additionally or instead of the shown rearward position also be arranged on the grip element 9 or be integrated in the door 6.
- the information of the detection sensor is transmitted to a control unit 23 (FIG. 1), which may be arranged in the door 6 or at another position in the housing 2, wherein the control unit 23 controls a door opening device by means of which, depending on the information of the detection sensor the door 6 is automatically opened. If it is detected that one or more fingers 21 are located within the detection area 22 or a finger 21 is contacted with the gripping element 9, then in this regard, at the latest when contacting the gripping element 9, it is recognized that an opening request of a user is present and via the control unit be responded to very quickly and the door opening device to be controlled.
- the front panel 10 extends in the x-direction to the extent that it is at least as long as the leg 18 of the grip element 9.
- the grip element 9 is stationary and thus not relatively movable relative to the door 6 positioned at this.
- the grip element 9 is formed in particular in the areas in which one or more electrodes 20 are arranged, made of an electrically non-conductive material.
- the oven 1 can be actuated via the handle element 9 for automatic door opening or moreover also via the operating device 12, wherein, for example, a button 14 or 15 is actuated to effect the activation of the automatic door opening device.
- the user can also make an individual configuration, depending on the needs, as to whether an activation and activation of the automatic opening device should take place via the grip element 9 or via the operating device 12.
- the drive motor is then actuated to automatically open the door 6 when the grip element 9 is touched when the door 6 is closed and when the pyrolysis operation of the oven 1 is no longer activated.
- the drive motor is not activated. In this regard, he is then disabled even with a gripping of the handle member 9 to further open the door or to close the door 6.
- the oven 1 has a child safety device which can be activated and deactivated via the operating device 12. If the child-safety device is activated, then the door-opening device can not be actuated automatically by gripping the grip element 9 in the closed state of the door 6 and the simple activation of the activation of the automatic door-opening device can not be achieved simply by operating a control element 14 or 15. Only then, when the child safety device is deactivated again or if specific further multiple combinable actions, for example actuation of one or more control elements 14 and 15 in a specific manner, are carried out, then the control of the automatic door opening device can be achieved even with the child safety device set.
- a door opening device 24 in a perspective view.
- This comprises a drive motor 25 with a drive shaft 26.
- the motor 25 is attached to a motor carrier 27.
- the door opening device 24 comprises a cam element 28, which is hollow-cylindrical and has a helically shaped cam track 29 at its end remote from the motor 25.
- the cam member 29 and the motor 25 are supported by a longitudinal ball bearing or thrust ball bearing 30, with which axial forces are avoided on the drive shaft 26.
- the door opening device comprises an electronic switch 31, which is arranged on the motor mount 27.
- This switch 31 is disposed adjacent to the cam member 28, being used to detect rotational positions of the cam member 28 about the axis of rotation, which is equal to the axis of the drive shaft 26, is trained.
- a transmission element 32 is attacking or rolling, which is designed as a ball bearing.
- This transmission element 32 is connected to a plunger 33 or attached to it.
- the plunger 33 is in mechanical operative connection with a door hook 34.
- the door hook 34 in turn is connected to a catch 35 for generating the locked state of the door 6.
- the plunger 33, the motor mount 27, the rotary latch 35 and possibly also other components are arranged in a housing 36 of the door opening device 24.
- FIG. 5 the door opening device 24 is shown in a perspective view from below. In this case, a first operating position is shown, namely the end position of the cam member 28, in which the transmission element 32 has arrived at the uppermost end of the cam track 29 analogously to the representation in FIG.
- Fig. 6 is a perspective view from below of the door opening device 24 is shown in an analogous representation to FIG.
- a further operating state is shown.
- Fig. 6 the basic position of the cam member 28 is shown, in which case the transmission element 32 has arrived at the lowermost point of the cam track 28.
- the motor 25 is electrically connected to the control unit 23 and is controlled via this.
- the control unit 23 and the door opening device 24 are associated with the door 6 of a door device 37 (FIG. 1).
- Fig. 7 is an enlarged detail I of the illustration in Fig. 4 is shown.
- the representation is slightly rotated relative to the view in FIG. It is both the switch 31 to the motor carrier 27 and the specific position to the cam member 28 to detect.
- the cam member 28 is rotatable about its longitudinal axis C by the coupling with the drive shaft 26, wherein between the initial position or basic position and the end position, only a full revolution about the axis C is performed.
- On a lateral surface 38 of the cam member 28, a survey 39 is formed on a lateral surface 38 of the cam member 28, a survey 39 is formed. In the direction of rotation, starting from the starting position shown in Fig. 7, the projection 39 extends to an end 40. This end 40 also defines the end of a first rotational position interval, which extends from the initial position to this defined by the end 40 rotational intermediate position.
- This zone or rotational position interval is shown between the lines shown by way of example only, which are not shown in the actual embodiment and merely show the limits of the first rotational position interval and thus the angular range ⁇ .
- the switch 31 can detect this position accurately by detecting the elevation 39. As long as the cam member 28 is within this first rotational position interval relative to the detection range of the switch 31, the zero position of the motor 25 is detected and the further movement of the motor 25 is stopped. In this position of the motor 25 and thus also of the cam member 28 is ensured that the door 6 can be completely closed manually again.
