Description

EXTRACTOR DEVICE FOR RAILS FOR A SUPPORT FOR FOODS TO COOK

DESCRIPTION

The invention relates to an extractor device for a support for food to be cooked with at least one rail with a sliding section. The invention furthermore relates to a cooking apparatus for housing such an extractor device.

Various types of extractor devices are known from the state of the art, which are suitable for housing a support for food to be cooked, such as a grill or an insertable tray, such as a baking tray or a baking dish. These extractor devices differ in their operation and ease of use for the user.

For example, document AT 22607 T shows an extractor device with a guide element and a sliding support, on which a support for food to be cooked rests, the food support for cooking being able to move on the sliding support inwards and out from the oven chamber.

In addition, document EP 1532402 A2 shows a furnace frame with a total extraction device, the total extraction device being mounted on an oven frame and frame frame of the oven or wire frame. An extractor device according to the preamble of claim 1 is known from that document.

In addition, extractor devices of interest are known from US 6,148,813 A, WO 2012/084733 A1 and EP 2314934 A2.

Particularly easy to operate for the user are extractor devices when they extract the support for food to be cooked on rails supported in a safe manner against overturning and even outside the oven chamber, preferably the support for food to be cooked completely. A particularly simple handling of the support for food to be cooked with food to be cooked is possible when the user can grasp the support for food to be cooked laterally when it is extracted, to extract the support for food to be cooked from the extractor device.

The extractor devices known up to now by the state of the art, such as, for example, furnace rib, suspension grid, normal extraction or complete extraction, do not make these user demands possible.

In addition, supports for food to be cooked that have elements of interlocking arrest are known from the state of the art. In this respect, the locking element is usually a stop element configured downwards, which runs on the side of the device towards a contract to stop extraction movements.

The document 102009002219 A1 shows a domestic appliance that has an extraction system that has a rollover protection for the payload support in the slide rails, which limits an inclination due to the gravity force of the payload support. an admissible limit value.

A drawback of this solution are the arrest contours oriented upwards to abut the extraction stop element, since they oppose the stacking capacity of the supports for food to be cooked and do not conform to the requirements of the design. In addition, the guide groove of the extraction system becomes dirty during the cooking operation in such a way that a malfunctioning of the locking element is foreseeable and thus a violation of the standard.

The basic objective of the invention is to achieve an extractor device for a support for food to cook that complies with the condition of a comfortable extraction of the support for food to be cooked, observing all the regulations related to overturning angles and to interlocking stop.

In the context of the invention, the objective is achieved in each case by all of the features of independent claim 1. Further advantageous configuration variants of the invention are described in the subclaims. The invention also finds application in a cooking appliance according to claim 13.

According to the invention, the extractor device for a support for food to cook a fixed rail and a sliding rail with a sliding section, on which the support for cooking food can slide, the sliding rail having an element of lateral guide, an interlocking element and a fastening element. The lateral guide element holds the food support to be cooked transversely to the extraction direction, so that the food support cooking is conducted laterally in its rest position and also in its extraction movement and can not slide in the lateral direction of the extractor device. The locking element constitutes a stop, in which a stop element can be made to stop by interlocking the support for food to be cooked, in order to stop an extraction movement of the support for food to be cooked, thereby preventing an involuntary removal of the food. Support for food to cook beyond a critical area for safety. The clamping element limits the overturning angle of the food support to cooking when it stops in its extracted position with its detent element in the locking element of the extractor device, when the lateral clamping area of the device is grasped. support for food to be cooked by the fastening element.

According to the invention, when viewed in the direction of insertion, the locking element is arranged behind the guide element and then the holding element. This sequence makes it possible for the support for food to be cooked to slide in its extraction direction from a rear rest position to a front rest position on the extractor device, until the interlocking stop element of the food support for cooking strikes with the interlocking element and then it is guided safely by the lateral guide element.

The guide element is mounted on the front end of the slide rail, for driving the food support to be cooked at the maximum possible distance from the fastening element.

When the food support to be cooked is located on the sliding surface in a position in which the interlocking stop element of the food support for cooking abuts on the locking element, the food support has to be moved to cook by a momentum of the user in the direction of extraction on the interlock element to extract the support for food to be cooked from the extractor device.

According to a variant, the extractor device presents the fixed rail and the sliding rail, both rails being connected to each other by means of a lock such that the sliding rail and the guide rail, in the extracted or inserted state, fit between yes so that a force has to be overcome to move the rails beyond the interlocking. This variant with respect to the rib seat or the suspension grid means an extraction, in particular a telescopic extraction, constituted as normal or complete extraction.

Preferably, the guide element is arranged essentially on the front side on the slide rail. The guide element can then be formed, for example, by a sheet metal part or a free-form element, for example a die-cast part or sintered part, which is for example screwed, pressed or welded to the sliding rail .

Particularly good handling of the food support to be cooked is achieved when the guide element has a lateral guide section. This constitutes a kind of rib that emerges upwards, in which the support for food to be cooked transversely with respect to the direction of extraction rests and guides the support for food to cook transversely with respect to the direction of extraction.

In addition, the guide element can have a stop, which serves the locking element of the support for food to be cooked as a stop in the direction of extraction. This additional stop gives the user the return signaling that when exceeding this extraction point, the support for food to be cooked is free of any conduction.

The extractor device has a locking element, which constitutes the stop for the interlocking stop element on the side of the support for food to be cooked, to stop the support for food to cook in its extraction movement. The locking element is mounted between the clamping element and the lateral guide element. This locking element can be an additional element, for example a sheet metal, which is mounted, for example welded or formed from the existing rail, for example by an inward or outward stamping. Alternatively, the locking element is formed from the rail, for example in the form of an overhang. The interlocking element also prevents incorrect operations, since it abuts on these interlocking elements and blocks a support for food to be cooked inserted upside down.

According to the invention, the clamping element is constituted to limit the tipping angle of the support for food to be cooked such that it laterally covers the support for food to be cooked, with which the lateral conduction of the support for food is ensured. cook in the back area of the extractor device. The width of the fastening element is limited, seen in the direction of insertion, preferably to 1-5 cm, thereby encompassing the support for food to be cooked in a small section, so that the lateral hold of the food is not impaired. support for food to cook, in particular in the section oriented to the user of the extractor device. The fastening element can be a part of the rail or an additional element, such as for example a piece of sheet metal or a piece of wire, which is fixed to the rail, for example welded. These configurations make the clamping elements and guarantee a functional safety of the element of stopping by enervation and the insurance against overturning. A particularly good fixing of the food support to be cooked in its inserted position is achieved when the fastening element has a step with respect to the sliding surface of the rail and arranged in the direction transverse to the extraction direction, which serves as a stop at interlocking stop element arranged in the support for food to be cooked.

Preferably, the fastening element constitutes an essentially C-shaped or U-shaped cross section. The opening of the C-shaped or U-shaped section towards the center of the food support to be cooked is then oriented. The base of the C-shaped cross section constitutes the fixing point of the clamping element in the extractor device, as well as the appendix disposed transversely to the extraction direction, which serves as a stop to the locking element of the support for food to cook. The part extending upwards of the C-shaped cross section constitutes the lateral guide of the food support to be cooked transversely to the extraction direction. The upper section of the C-shaped cross-section constitutes the holding section, which forms the supporting surface for a support for cooking food to be tilted.

Preferably, the holding element has an insertion aid, which centers the support for food to be cooked in the introduction movement in the vertical direction, in order to position it more easily. This insertion aid can be an additional element which, seen in a direction transverse to the direction of extraction, is essentially formed with a trapezoidal shape. Another configuration variant of this introduction aid is intended to constitute the insertion aid especially sliding and without scratches with respect to the support for food to be cooked.

The fastening element has, seen in its cross section, a height H between the sliding surface and the upper section of the C-shaped cross section, to determine the tipping angle. If the support for food to be cooked swings in its movement of extraction, because for example the center of gravity of the support for food to cook comes to be on the front edge of the extractor device, then it hits the support for food to cook on the surface of stop of the clamping section. Then the height H defines the maximum tipping angle, in accordance with the regulations in force and prevents a too abrupt turn of the support for food to be cooked. In this way an overflow or fall of the food to be cooked is prevented from the support of the food to be cooked. Preferably the distance between the clamping element and the guide element is greater than half the length of the support for food to be cooked. Then it is the distance between the clamping element and the guide element lower than the distance in the support for food to be cooked between the rear edge of the support for food to be cooked and the element of detenting by interlock.

When the support for food to be cooked is in the extracted position on the extractor device, it is completely outside the oven chamber. This is possible by moving the slide rail away from the extractor device and continuing to move the food support to be moved on the sliding section of the extractor device until it stops at the stop.

The invention achieves the objective additionally with a cooking appliance having an extractor device.

Other advantages and details of the invention will be described in more detail on the basis of the exemplary embodiments shown in the schematic figures. In this regard it shows:

1 shows a schematic representation in perspective of an embodiment of a household appliance according to the invention with an exemplary embodiment of an extractor device according to the invention;

2 shows a perspective representation of an extractor device;

3 shows a perspective representation of a lateral guide element of the extractor device; 4 shows a perspective view of a fastening element of the extractor device;

5 shows a perspective representation of the extractor device in a first position; 6 shows a perspective view of the extractor device in a second position; 7 shows a perspective view of the extractor device in a third position; 8 shows a perspective representation of an extractor device that is not part of the present invention, in a fourth position.

In the figures, the same elements or elements that function in the same way as the same references have been provided.

To achieve a description without contradictions of the directions in a cooking appliance, a descriptive coordinate system is introduced in figure 1. This defines in the X direction the front of the device, starting from the right side of the device to the left, as well as in the direction Y the direction of insertion, starting from the state in which the support for food to be cooked is extracted in the direction of insertion, as well as in the Z direction height of the cooking appliance, starting from the underside of the appliance towards the upper side of the appliance.

In figure 1 a cooking appliance 1 for preparing food is shown in a perspective representation, which in the exemplary embodiment is a cooking oven. The cooking appliance 1 includes a chamber of the oven 2, which is delimited by the side walls 3 of the oven. On the front side, the oven chamber 2 has a loading opening, which can be closed by means of a door 4. In the side walls 3 there are respective seats 5 for the support for food to be cooked, which are suitable for housing supports for foodstuffs. cook 6, such as grills, baking sheets or similar accessories. The seat 5 for the support for food to cook presents in this respect different insert heights, which in the embodiment example of figure 1 are constituted differently. There, the upper insertion height shows a single suspension grid, the lower insertion height showing an extractor device in the form of a telescopic extractor. In this regard it may be a normal extraction or a complete extraction. The following description of the figures refers to a rail extraction system, but it can be moved in terms of its functions also to a suspension grid.

Figure 2 shows a perspective view of the extractor device 7. Such extractor devices 7 that can be made telescopic consist essentially of a fixed rail 8, which is rigidly or adaptably fixed to a seat 5 for the support for food to be cooked or either fixed or such that it can be fitted to a side wall 3. This fixed rail 8 is essentially suitable for receiving sliding rails and moving in the Y direction, by means of rollers or sliding bodies (not shown). The surface of the sliding rail 9 then constitutes the support area and the sliding section 11 for the support for food to be cooked 6. The length of the sliding rail 9 is essentially designed based on the length of the support for food to be cooked. , whereby the same, after insertion in the oven chamber, hits the rear stop 10, not protruding from the front edge 12. The rear edge 10 is formed in this embodiment by a so-called pin. At the front end 12 of the extractor device 7 is the guide element 13, which secures the support for food to be cooked 6 for the lateral conduction in the X direction. The extractor device 7 is made in the exemplary embodiment represented by a profile in frame as sliding profile 9, but it can also be formed by the so-called "C" rails. Starting from the front end 12 of extractor device 7, the locking element 14 is arranged on the sliding section 11 in the Y direction. stop a stop element by interlocking the support for food to be cooked. Continuing with the course of the sliding profile 11, the clamping element 15 is located in the direction Y to limit a tilting angle of the support for food to be cooked 6. The extractor device 7 shown in figure 2 is the extractor device 7 arranged in the left side wall of the oven chamber 2. This is constituted with mirror symmetry with respect to an extractor device 7 arranged in the right side wall. In each case two extractor devices 7 arranged facing one another on an insertion level, result in a pair of extraction rails, which together house the support for food to be cooked 6 and seen in the Y direction, perform the support for the insertion and the removal. Such extractor devices are resistant to heat, in particular resistant to pyrolysis, suitable for dishwashers and resistant to microwaves.

Figure 3 shows in a perspective representation 13 the detail of a guide element 13. This is disposed at the front end 12 of the slide rail and thus constitutes the front closure, as well as the visible front surface of the extractor device 7. The guide element 13 is stamped by means of a fixing element not shown with the slide rail 9. Alternatively to this embodiment, the guide element 13 can be welded to the slide rail. The guide element 13 of a left extractor device 7 has a guide section 16 seen in the X direction at the left end. This guide section 16 extends in the Z direction and forms a kind of rib, the which, adapted to the support for food to be cooked 6, is suitable for driving the support for food to be cooked 6 in the X direction and thereby transversely to the extraction direction AND such that the support for food to be cooked 6 can not slide laterally from the sliding rail 9. This is especially important, since the traditional extraction systems have a stop at the front end 12 analogously to the rear stop 10 and thus support the support for foods to be cooked rigidly on the slide rail 9 and are not made sliders by themselves. Furthermore, the guide element 13 has a stop area 17, which causes the stop of the food support to be cooked in the extraction direction X, starting from the sliding section 11 of the sliding rail. This stop of the support for food to be cooked 6. in the stop area 17 informs the user of the point at which the support for food to be cooked leaves the sliding section 11 in the direction of extraction and thus is in front of the front end. 12 of the extractor device 7. In addition, the stop area 17 fulfills a safety-relevant characteristic, since a support for food to be cooked 6 inserted or placed upside down by the user is stopped by its stop element by locking in the direction of extraction And in this stop. Viewed frontally, the guide element 13 is extended by the contour of the sliding rail 9 in the direction of the side wall 3, and This results in a longer stop area in the X direction, which serves the stopping element by enervation of the support for food to be cooked 6 as a stop surface.

The locking element 14 is configured in FIG. 2 as a welded lamella. Alternatively, the locking element 14 can also be clicked or configured as a recess or directly from the sliding rail 9. In this case, the locking element 14 extends, analogously to the guide element, even beyond the cross section of the rail. sliding 9 or of the sliding section 11 in the X direction, to provide the stop element for locking the support for food to be cooked 6 a stop.

Figure 4 shows the perspective representation of the fastening element 15. The fastening element 15 consists essentially of the areas: lower clamping section 18, rear clamping section 19 and upper clamping section 20. The clamping element 15 with its three clamping sections, 18, 19 and 20, result in a substantially C-shaped section, whose opening is oriented towards the center of the support for food to be cooked. In this respect, the lower clamping section 18 distances the clamping element 15 of the sliding rail 9 in the direction of the side wall 3, preferably analogously to the lateral offset of the guide element 13. The rear clamping section 19, which is essentially arranged at right angles to the lower clamping section 18, it extends in the Z direction and defines the height H. The height H is adapted to the support for food 6 to be cooked on the extractor device 7, depending on the standard, which prescribes the magnitude of the maximum permissible tipping angle for the support for food to be cooked 6. The greater the height H, the greater the maximum tipping angle. The upper clamping section 20 constitutes the stop which opposes the support for food to be cooked 6 when it tilts. Furthermore, an input assist device 21 is mounted on the fastening element 15 to make it easier for users to position the food support 6 to be cooked in the extractor device 7. To this end, it presents the device for assisting in the introduction 21 bevels and Rounding The width of the clamping element 15 is adapted to the geometrical conditions taking into account the tipping angle. The lower clamping section 18, which is oriented away from the sliding rail 9, also has the functionality of a stop for the locking element of the support for food to be cooked 6. In the insertion movement, the sliding rail must first stop. 9 in its rear position before the food support for cooking 6 slides backwards on the sliding surface 11. Only then will the locking element move from the support for food to be cooked 6 on the lower holding section 18 and gives the user feedback (feedback) that the support for food to cook 6 has reached its final position. In the extraction movement it fixes the lower stop 18 the food support 6 in its position and thus makes it possible for the food support 6 to move on the sliding section 11 first to exit the rail outwards of sliding 9 supported from its rear position to its forward position on the fixed rail 8. This means that the lower securing section 18 fixes the support for food to be cooked 6 in its immobile position on the sliding rail until that sliding rail 9 has reached its extracted position with respect to the fixed rail. This function of the lower clamping section 18 can also be carried out by means of an additional element in the clamping element 15.

Figure 5 shows the support for food to be cooked 6 in a first position. In this regard, the state in which the support for cooking food 6 rests on the rear stop 10 of the extractor device 7 is shown and in a preceding stage the so-called inserted state has been removed from its rest position, up to a position in which the extraction rails of the extractor device 7 are extracted to the maximum. This state corresponds to the extracted state of the normal extraction. In this position the user carries the food support to be cooked 6 by holding the food support to be cooked by its front edge 22 and pulling in the Y direction. In this position the food support to be cooked on all four sides is held, when it rests in its rear area in the rear stops 10, laterally by the fastening elements 15 and is held forward by the locking element of the support for food to be cooked 6 that rests on the fastening element 15. Additionally, the stop area 17 is a forward stop.

Figure 6 shows the support for food to be cooked 6 in a second position, in which the user has grasped the support for food to be cooked 6 by its front edge 22 and has driven it by exerting a force to the front stop position. The locking element of the food support 6 was then brought to the cooking position 6 on the stop of the holding element 15, so that the support for cooking food 6 could be moved on the sliding section 11 until the stop element stops. by interlocking the support for food to be cooked 6 abuts in the stop area 17. This point of the retaining element 14 on the sliding section 11 is selected such that the fastening element 15 still comprises the rear edge 23 of the food support to cook 6, to prevent the overturning of the support for food to be cooked 6. In this position the user has the possibility of grabbing the front edge 22 and now grabbing the support for food to be cooked 6 by its lateral support section 24 This possibility of grasping is especially preferred by the user, since he can now better drive the support for food to be cooked 6, which most of the time is som is a significant force of the weight of the food to be cooked, since he can grab the support for food cooking 6 closer to its center of gravity seen in the direction Y. Thus can be avoided involuntary tilting of the support for food to be cooked 6 outside the guide by means of the extractor device 7. Figure 6 also shows the position to which it has to take the user the support for food to cook 6 to introduce the same in the extractor device 7. Then the rear area 23 of the support for food to cook 6 is supported on the sliding section 11 and moves in the Y direction. as the interlocking stop element of the support for food to be cooked 6 has been displaced on the stop 18 of the holding element 15, there is the support for food to be cooked 6 in its final position. In the meantime, the sliding rail 9 has rolled on the fixed rail to its final rear position.

Figure 7 shows the support for food to be cooked 6 in the same position as in figure 6, but in the maximum allowed tipping position. To this tilting position is reached by the user, who tightens on the front edge 22 of the support for food to be cooked 6, for example so that the food to cook runs by the leading edge or the center of gravity of the food to be cooked it is located near the leading edge 22 of the support for food to be cooked 6. The support for food to be cooked 6 that is overturned forward is then hindered by the fastening element 15 so that it does not exceed the maximum prescribed tipping angle.

Figure 8 shows an alternative extractor device, which is not part of the present invention, in which the function of the locking element 14 is included in the guide element 13. Due to this the position of the fastening element in the direction is shifted And towards the leading edge 12.

The width of the elements mounted on the sliding rail 9, in particular guide element 13, locking element 14 and holding element 15, is kept low, to facilitate lateral grip and to prevent the extractor device from becoming dirty.

A suspension grid is also a self-contained object of the invention, which has the characteristics of fastening element 15, locking element 14 and guide element 13, as well as its functional characteristics.

Other features of the invention result from the claims, the figures and the description of the figures. The features and combinations of features cited in the description, as well as the characteristics and combinations of features cited below in the description of the figures and / or shown only in the figures, can be used not only in the combination indicated in each case, but also also in other combinations or in isolation. Thus, they are also to be considered included in the invention and published by the same embodiments that are not explicitly shown or explained in the figures, but which are deduced and can be generated from the explanations of the description by combinations of separate characteristics.
