Description

The invention relates to a cooking appliance with a door for closing a cooking chamber and with a housing in which a storage space is formed, in which the door is retractable, wherein the storage space is limited by a technical part, which is a vertical side wall, in which a guideway is designed for a guide carriage for guiding the sinking movement of the door in the storage space.

From the DE 10 201 206 577 A1 is a household appliance with a retractable into a storage space door with a guide slot backdrop for moving a bearing bracket of a storage unit known.

Out DE 10 2008 010 526 A1 a home appliance device with at least one door unit is known. The door unit is attached with hinges to a housing of the household appliance and can be pivoted relative thereto and in the open state can be lowered into a storage space formed below the receiving space. The hinges also include a U-shaped bracket as a hinge part, on which two rollers are rotatably mounted. The bracket is rigid in itself and pivotable about an axis of rotation.

Also from the EP 2 57 378 A1 is a household appliance with a retractable door known. Again, a hinge with a U-shaped bracket is designed as a storage unit in the form of a hinge rocker with two rollers. This hinge rocker is also rigid in itself, but rotatably arranged on a hinge housing.

The same is true of the EP 2 574 712 A1 known, wherein the design of the hinge is also a hinge housing and a rotatably arranged thereon bearing unit in the form of a U-shaped bracket, which is a hinge hook, is provided.

As a result, a so-called engineering part, which has guideways for this bearing part and receives the rollers when sinking the door to dimension accordingly. In addition, this configuration at specific door positions, when the door is already partially open, and at the same time enters the storage space, a distance between the door leaf of the front front side upper edge, which limits the front storage space, very small. As a result, if necessary, a bumping of the door leaf during the further closing movement or during opening may occur. With regard to this vertical height, the critical points are the flange at the lower area and thus at the lower edge, as well as the intermediate floor of said technical part, which delimits the storage space from above. This intermediate floor forms in particular an upper cover of the storage space.

Furthermore, from the DE 10 2015 226 009 A1 a cooking appliance with a retractable door known. There, the storage space for the door is also limited by lateral vertical, in particular plate-like, side walls. In these side walls, which are technical parts, also guideways for a slide carriage or a guide carriage are formed. In this embodiment, these guideways are viewed in the height direction of the cooking appliance and thus also in the height direction of these engineering parts far below in these technical parts. As a result, a guiding movement of the door can be given a specific sequence. In particular, it is provided in this embodiment that a front end and a rear end of this guideway are formed almost immediately adjacent to a lower edge of this engineering part. The door is thus arranged at the beginning of movement as well as at the end of movement far below.

By such a configuration, the retractability of relatively wide doors is limited. Because the space is limited in this context not only in width but also in height. By the guideways are so far down, the pivoting movement and retraction of the known doors is such that they require significant space in the height direction.

It is an object of the present invention to provide a cooking appliance with a retractable door, wherein here a technical part is improved to the effect that the storage space is designed to retract in the width of different doors and in this respect the retraction is made compact. In this context, therefore, a concept should be made possible in which the flexibility with regard to the use of different doors is improved.

This object is achieved by a cooking appliance having the features of claim 1.

One aspect of the invention relates to a cooking appliance with a door for closing a cooking chamber. The cooking appliance also has a housing in which a storage space is formed. In this storage space, the door is retractable. The storage space is a separate room to a cooking chamber of the cooking appliance. In the oven food can be introduced for cooking. The storage space is limited by at least one technical part, which is in particular a wall part. This technical part is in particular a vertical side wall. In this technical part is a guideway for formed a guide carriage of the cooking appliance. The guide carriage is designed to guide the countersinking movement of the door into the stowage space and thus also for the retraction of the door from the stowage space. The cooking appliance has a height direction. This technical part is oriented in the height direction of the cooking appliance. This engineering part has a height when viewed in this height direction of the cooking appliance. The guideway is in terms of their measured in the depth direction of the cooking appliance length (straight length I in the depth direction) at least 80 percent formed in an upper half of the height of this technical part. The guideway is thus laid in this embodiment in the engineering part very far up. At least a substantial length of the guideway is located in this upper half of the height. Such a configuration improves the guiding movement for doors. In particular, relatively wide doors, which have a relatively wide windscreen can thus easily and practically substantially with a corresponding countersinking movement, as it is performed in conventional known cooking appliances, as mentioned above, are also sunk in the storage space. This has the additional advantage that even with relatively wide doors, the cooking appliance can be used with relatively many equal components and yet the sinking of these doors in the storage space can be done easily and continuously. By this explicit position of the guideway in the engineering part thus a relatively wide door can be sunk with a given space and this with as much as possible movement compared to the conventional known concept. Through this overhead training the guideway is created corresponding space below the guide structures for a wide door. For in particular, this width is given by a front screen, which is an outer pane of the door. Since this windscreen during down pivoting and thus also when swinging into the stowage space, so to speak, represents the lower part of the door in the height direction, a relatively large installation space in the width direction is required in the height direction of the stowage space relatively far down and thus also near the ground. By Nachobenverlegung the guideway, this is easily achieved, so in the context then advantageously this wider door, especially with its windscreen, can dip below the guideway in the storage space. It is thus also possible that the windscreen when immersed in the storage space and thus during retraction until the final inserted end position is reached, is arranged so that the guideways and the windscreen are arranged in the width direction of the cooking appliance overlapping.

It is preferably provided that the guideway has a height considered in the height direction and the guideway is formed over its entire height in this respect over this at least 80-percent length portion in the upper half of the technical part.

It is preferably provided that the guideway is formed over the entire length in the upper height half. Again, this relates in particular to guideways over their entire height. This means that the guideway is formed over its entire length and with its entire height in the upper half-height of the engineering part. The above advantages are achieved in particular.

In an advantageous embodiment, it is provided that the guideway is formed with a, viewed in the depth direction of the cooking appliance, the front guide track end and viewed in this depth direction with a rear guide track end. In particular, the front guide track end and / or the rear guide track end is formed in this upper height half of the engineering part. In particular, this again relates to the full height of the front guide track end and / or the rear guide track end.

These height indications and in particular the position of the guide track in the upper half of the height are dimensioned in particular with respect to the highest point of an upper edge of the engineering part.

In an advantageous embodiment, it is provided that the engineering part has an upper edge, which is at least 80 percent of its length, preferably at least 90 percent of its length, preferably completely over its entire length without height offset and thus formed offset in height. In particular, the engineering part has an upper edge, which is formed over the length of the guideway without such a height offset. By such a configuration, the guideway with a relatively large length portion, namely in particular at least 80 percent, may be formed in the upper half-height of the engineering part in a particularly advantageous manner.

The technical part is preferably at most 40 percent, in particular at most 30 percent, in particular at most 20 percent, longer than a length portion of the guideway dimensioned in the depth direction.

It is preferably provided that the guide carriage has a receiving part, on which two separate, objective connection points or connection points for rollers (bearing rollers, plain bearings) of the guide carriage are formed. The receiving part has at least one separate third door for the door. The three attachment points are formed at three different positions on the receiving part. By means of such a configuration, the different height positions of these attachment points can also be designed individually in this regard. Due to the specific height position of the guideway and this receiving part is to be adapted accordingly. In this context, the receiving part is namely moved during the retracting movement or the outward movement of the door relative to the guide track. This results in different positions of this receiving part, so that those components which are connected to the receiving part, always also each must be positioned so that a jerk-free movement of the door is made possible and beyond no abutment of components on other components occurs. Thereby, a receiving part with such a plurality of attachment points, which are spaced and non-contact with each other on the receiving part, is thus preferred.

It is preferably provided that viewed in the height direction of the cooking appliance and viewed in the closed state of the door, wherein the guide carriage is in a home position, the two first attachment points are formed at a higher position on the receiving part, as the third attachment point. This means that the third attachment point, viewed in the height direction, is designed offset downwards relative to the two other first attachment points. For this embodiment, on the one hand, the rollers of the guide carriage are moved relatively far upwards, so that they can be performed accordingly in the high-level guideway. On the other hand, the door connection is laid down so that even with wider doors, the windscreen below the track can dive into the storage compartment and can move accordingly.

It is preferably provided that at the third connection point a first connecting rod or coupling rod for connecting the guide carriage is connected to a further guide carriage of the cooking appliance or is connected thereto. The guide carriages run synchronously with each other.

Preferably, it is provided that the door is pivotally connected to the third connection point.

In an advantageous embodiment, it is provided that the receiving part has a separate fourth connection point, which is formed at a fourth position or fourth position different from the three other connection points on the receiving part. This fourth attachment point is thus also formed at a distance from the other three attachment points. Such a configuration makes it possible to connect further components to the receiving part, so that on the one hand the stability of the construction is increased, on the other hand further movement and guiding couplings are made possible.

In particular, the receiving part is plate-like. At this receiving part are then, in particular of such a base plate in particular projecting, corresponding connection points formed.

It is preferably provided that viewed in the height direction of the cooking appliance and in the closed state of the door, wherein the guide carriage is in a home position, the fourth connection point between the first and the second connection point on the one hand and the third connection point on the other. This then also means that viewed in the height direction at the top, the two first connection points are formed, offset down the fourth connection point is formed and in turn offset down the third connection point is formed.

In an advantageous embodiment, it is provided that a second connecting rod or coupling rod for connecting the guide carriage is connected to a further guide carriage of the cooking appliance at the fourth connection point. This makes it possible, on the one hand to attach different connecting rods at different positions, in which case only one of the two guide rods can then be coupled to the third or the fourth connection point, in particular can be attached thereto. However, it may also be provided an embodiment in which such two separate connecting rods are present.

It is preferably provided that the guide carriage has a receiving part, on which a, in particular groove-like, drip tray is arranged. This receiving part is formed in particular plate-like. It is advantageously the above-mentioned receiving part.

It can be provided that the drip tray is integrated with the receiving part and thus formed integrally therewith. In an alternative embodiment it can be provided that the drip tray is non-destructively releasably connected to the receiving part, in particular directly connected thereto. In this context, for example, a plug connection or a latching connection may be formed. However, it can also be provided a screw connection.

In particular, it is provided that the storage space viewed in the vertical direction is bounded above by an intermediate floor, which thus forms a cover of the storage space. It is preferably provided that the intermediate floor is arranged with groove-like holding profiles on the engineering part. This allows a correspondingly stable attachment. The holding profiles can be integrated in the intermediate bottom edge. However, the holding profiles can also be separate components. Preferably, the holding profiles are rectilinear rails, which have a channel shape in cross-section, wherein preferably a side web or side leg is formed projecting from an upper edge of a channel leg.

The door can be pyrolysetauglich. However, it may also be designed to be designed for a cooking appliance that does not have a pyrolysis function. The door may have a handle on the front side and thus in particular on an outer side of the front window. This handle can be arranged stationary. However, the handle can also be designed to be pivotable. In such an embodiment, the handle is then pivoting forward when the door is inserted into the storage compartment. As a result, the handle is oriented in the inserted end position forward and freely cantilevered, so that a user can easily grip the handle.

In particular, it is provided that a center section of the guide track, wherein this center section is viewed in the longitudinal direction of the guide track, is formed in a straight line. It is preferably provided that a middle section of the guide track is formed in an upper third of the height of the technical part.

Preferably, the receiving part is formed such that the third attachment point and / or the fourth attachment point are not arranged so that they have the same center of the circle. The same applies to the first two connection points.

Preferably, it is also provided that a coupling structure, in particular a coupling hook, for coupling with a bearing bush, on which in turn a connecting rod is inserted or connected, is taken over into the receiving part, in particular integrated therein. As a result, the stability of this coupling hook is increased.

Preferably, the door has at least one hinge, which is coupled to the guide carriage. This hinge has in particular a hinge bracket, which is preferably U-shaped and can also be referred to as a hinge arm. This is also part of a storage unit. This hinge bracket has two rollers which engage in guideways on side edges of the door and roll along it. On the other hand, this hinge bracket is rotatably mounted on the housing and / or a hinge housing of the hinge. The hinge housing is arranged in particular above or in the region of an upper edge of an engineering part.

In particular, it is provided that the hinge has a hinge housing with which the hinge arm is rotatably connected and the drag lever is pivotally mounted on the hinge housing. In particular, the door is directly connected to the hinge arm. By then the drag lever is directly coupled to the hinge housing, correspondingly occurring forces can also be transmitted improved here, since the hinge housing is also a more robust and larger component than the hinge arm. In addition, in turn, the connection concept between the hinge arm and the door is not affected by this specific coupling point and the corresponding relative movements when moving the door between the door and the hinge arm are not affected. In particular, the drag lever is also pivotally mounted to the hinge arm.

In particular, it is provided that the hinge arm is a one-piece bracket, which preferably has a U-shape. On the hinge arm, in particular on one leg of this U-shape two spaced-apart rollers are arranged, which are rotatable. With these rollers, the hinge arm engages guideways formed on the narrow vertical side edges of the door. As a result, a mechanically stable guidance, given non-jerk relative movement possibility between the hinge arm and the door. This has particular advantages when moving the door into the storage space and the trajectories occurring between the door and the hinge arm.

It is advantageously provided that guideways, in each of which a guide slide is guided, are formed on the housing at lateral engineering parts which delimit the storage space. The guide slides formed on opposite sides are preferably connected to a connecting rod, so that the position can be maintained relative to one another and no tilting or twisting occurs relative to the movement. This positional coupling between the guide carriages enables jerk-free and uniform movement along the guideways. The door is connected in an advantageous manner at its lower end with these guide carriages, in particular rotatable associated with it. The guide carriages are separate components to the hinge arms. The guide slides are stationary and thus not slidably connected to the door on the door, wherein at the connection point a rotation axis is formed, around which then the door can rotate relative to a guide carriage. In contrast, not only a relative movement with respect to a rotation allows each other by the hinge arms with the above-mentioned roles, but also given by the also formed on the side edges and already mentioned guide groove or guideways in the door a sliding movement between the door and a hinge arm.

In an advantageous embodiment, it is provided that the storage space in the height direction at least at one entrance has a clear width of less than or equal to 45 mm, in particular between 40 mm and 44 mm. Preferably, it is provided that this clear width viewed in the vertical direction is formed over at least 50 percent, preferably at least 80 percent, in particular at least 90 percent, of the depth of the storage space dimensioned in the depth direction.

Such a configuration of the storage space is designed to be particularly compact, so that the cooking chamber can be provided with maximum extent. If the housing of the cooking appliance has a standard standard size, the cooking space can be maximized by means of this compact storage space. Nevertheless, the retraction and extension of a wide door in or out of the storage space is possible.

In an advantageous embodiment, it is provided that the door has a thickness between 35 mm and 45 mm, in particular between 38 mm and 42 mm, preferably 40 mm. In such an embodiment, it is then also possible that the door has a multi-disc package with at least three panes, in which case a front pane, an inner pane and at least one intermediate intermediate pane can be provided. The disks are oriented parallel to one another and constitute plate-like elements, in particular made of real glass. Especially with at least three such separate disks, the cooking appliance can in particular also be designed with a pyrolysis function.

Especially in such a configuration in which the door has the above-mentioned advantageous thickness, and the storage space has the above advantageous height, the thickness is of course always smaller than the height dimension of the storage space, in this respect, a relatively thick door in a then only insignificantly higher storage space be retracted. It is then made possible by the above-mentioned mechanism that a corresponding retraction or extension operation of the door is made possible, although the storage space is only slightly higher than the thickness of the door. In particular, this is achieved in that a retraction of the door during the pivoting movement, in particular from the closed position into a horizontal open position, not or only insignificantly enters the storage space and the main retraction takes place starting from the horizontal open position, so that essentially after the Pivoting movement only the linear movement of the door into the storage space takes place.

In an advantageous embodiment may be additionally or instead provided that the door on its outer side viewed in the width direction has a width between 530 mm and 545 mm, in particular between 535 mm and 540 mm. By such a wide door, the Spaltmaßgestaltungen can be improved. In particular, in this context, the gap dimensions to adjacent components, such as, for example, front strips, which are formed on the front as visible components or outer parts of the cooking appliance, can be improved. In particular, these gaps can be set relatively small. It can be achieved in the context of the above-mentioned embodiment of the door with its specific width dimension a uniform frontal appearance between Gargerätvarianten, on the one hand only with a hinged door, on the other hand with the above-mentioned retractable door. When the doors are closed, a uniform appearance can then be offered with these two cooking appliance variants.

In a further independent aspect, a cooking appliance is formed with a housing in which a cooking chamber is formed. The cooking appliance also has a door, which is arranged to close the cooking chamber. The cooking appliance has a separate storage space to the cooking chamber, which is formed in the housing and in which the door is retractable in the open state. The storage space, viewed in the height direction of the cooking appliance, has a clear width of less than or equal to 45 mm, in particular between 40 mm and 44 mm, at least at one entrance of this storage space, and / or the door has a thickness of between 35 mm and 45 mm, in particular between 38 mm and 42 mm, on and / or the door, in particular a windscreen of the door, has a width between 530 mm and 545 mm, in particular between 535 mm and 540 mm.
