Description

DOMESTIC APPARATUS TO PREPARE FOOD WITH A ROUTE OF GUIDE FOR THE ACCOMMODATION OF A SUPPORT FRAMEWORK FOR A COOKING PRODUCT SUPPORT

The invention relates to a household appliance for preparing food, with a cooking space that is delimited through at least one side wall. The domestic appliance further comprises at least one guideway, which is configured next to the inner side of the side wall, and for the accommodation of a support frame for a cooking product support.

From EP 0 952 403 A2, a cooking oven with a telescopic extension is known. Next to the inner sides of the side walls of a muffle, which delimits a cooking space, guideways are configured as notches. These are provided for the accommodation of a support frame for a cooking product support. The support frame has telescopic extensions, on which the cooking product support can be positioned. However, the height of the guideway is only sized so that only the support frame can be housed. Therefore, the cooking product support is narrower in terms of its width and, therefore, the problem arises that, then, if the support frame is removed from the cooking space, it is not possible to Introduction of the cooking product stand alone. This is then disadvantageous, if a cooking oven is configured for a pyrolytic function and, during a pyrolytic function, this support frame with the telescopic extensions must be removed so as not to damage it due to the high temperatures during the pyrolytic function. Since, however, in this regard, the cooking product support must remain in the cooking space in order to be able to incinerate impurities, such as cooking product residues, grease accumulations, and the like, in the furnaces by pyrolysis. known cooking this is possible only in a very limited way.

It is the task of the present invention to create a household appliance for preparing food, in which a flexible and variable susceptibility of the support frame and of a cooking product support in a cooking space is possible.

This task is solved by means of a domestic appliance that has the characteristics according to claim 1.

A household apparatus according to the invention for preparing food comprises a cooking space, which is delimited by at least one side wall. Likewise, at least one guideway is provided, which is configured next to the inner side of the side wall, and for the accommodation of a support frame for a support of cooking product, or is configured by means of a hook hitch. Way itself known. The guide track has a lower guide surface that has at least one subsidence, in which a support piece of the support frame is inserted, so that the support frame is positioned sunk downwards with respect to a positioning on the lower guide surface, configured outside the subsidence, of the guide track. By means of such a configuration, a positioning of the support frame and the cooking product support remarkably more flexible and variable is possible. The possibility of accommodation in the guideway, as regards these components of the support frame of the cooking product support, is remarkably improved and expanded.

The support part of the support frame is preferably a lateral convexity in a support rod of the support frame. Through such a configuration, an especially cheap configuration of components, highly stable, and mechanically loadable is possible. So to speak, a rod of the support of a piece is created, which can be positioned in the sinking by means of this clamping piece. Through such a lateral convexity, the construction height of the support frame can also be kept unchanged, so that, also in this respect, there is no limitation.

Likewise, through a bending and stamping of such type on the support rod as a corresponding clamping piece, a clamping piece configured with the lowest possible weight is created.

Preferably, the subsidence has a depth that is less than the height of the clamp. By means of such a configuration, a displacement of the support frame is achieved downwards, although the support piece of the support rod protrudes minimally in the vertical direction of the lower guide surface. In this way, a direct support of the cooking product support on the lower guide surface can be avoided when the support frame is inserted into the cooking space, so that wear of the cooking product support can be avoided and of the guideway by rubbing each other too often.

Furthermore, by means of such configuration, the support frame can also be removed more easily, especially when a cooking product support is positioned on it. Since, if a cooking product support is also arranged on the support frame, on which an even heavier cooking product is additionally arranged, the possibility of complete extraction requires a user considerable effort, whereby a positioning and configuration of the sinking of this type guarantee an improved maneuverability and easier extraction.

Preferably, the height of the guideway in the area of a subsidence is greater than the summed height of the clamping piece and of a side flange of a cooking product support positioned on the support frame extending into the interior of The guide way. This is an especially noteworthy advantageous embodiment, since it gives a configuration of the domestic appliance with versatile and multifunctional use. On the one hand, a cooking product support can be used that extends with its lateral flanges in the guideway. Only this possibility already provides, therefore, unlike the prior art, the option that the cooking product support can be introduced into the cooking space also without the support frame, and sustained through guideways . This is especially advantageous in types of operation of the household appliance where the support frame is not needed or, even, must be removed to protect it from deterioration. In this sense, it is worth mentioning, by way of example, pyrolysis.

The domestic appliance present here is configured, in particular, with such a pyrolytic function.

Also, if the cooking product support and the support frame are arranged in the cooking space, it can be achieved that both extend into the guideway, since their total construction height is smaller in this area than extends in the guideway.

In particular, it is provided that the height of the track guide outside a subsidence is sized smaller than this summed height of the clamping piece and of a lateral flange, which extends into the interior of the guide track, of a support of cooking product positioned on the support frame. By means of such a configuration, the reliable and safe positioning of the components on the guide tracks can also be guaranteed, since an assurance against runoff of the support frame is also guaranteed, since, in the introduced state, due to these height conditions in the case of positioned cooking product supports, slippage outside the subsidence can be avoided, since before the collision with the upper and lower guide surfaces of the track guide would occur.

Preferably, at least two sinks configured at least one another are formed along a guideway. Thus, the stable positioning of the support frame can be improved, and the safe position installation can be improved.

Preferably, the subsidence is provided to have equal dimensions and equal conformations.

It may also be provided that the sinks preferably have different dimensions and different conformations. In this way, a user-friendly operation can be offered. Thus, it is especially advantageous for a front sinking to constitute a shell-shaped cavity, which is laid out in a way that runs down relatively flat. By means of this configuration, a smooth introduction by sliding of the clamping piece into the sinking can be guaranteed. Likewise, a simpler withdrawal is also possible, since, in a way, a perpendicular elevation of the support frame is not directly necessary.

It may also be provided that another subsidence, especially a subsequent subsidence, constitutes an angular cavity. Thus, a particularly accurate installation and position clamping can be achieved. In this way, unwanted slipping to one side and another, back and forth, of the support frame can be avoided.

Especially advantageously, it is provided that a guideway is a notch-like pattern configured on the side wall. By means of such a configuration, the guideway is formed in a piece in the side wall, and no additional pieces are necessary that should be mounted next to the side wall, or installed in another way. Also, through such a configuration, undesired tolerances can be avoided during assembly.

It can also be provided that a guideway is a separate part, which is installed next to the inner side. As an example, a grid construction is mentioned here, which can be fixed in a releasable or non-releasable manner to the inner side. The matched grid rods, which run horizontally, then form guideways and, consequently, insertion planes. In such a configuration, the lower guide rod can then have the at least one collapse.

The cooking product support preferably has a width such that, in the state introduced into the cooking space, it extends into the interior of guideways configured on opposite side walls. Preferably, in the state removed from the cooking space support frame, the cooking product support introduced into the cooking space is contained in the guideways.

Preferably, an extraction device is arranged next to the support frame, especially a telescopic extraction device. Such a telescopic extension comprises a fixed rail, which is stationary arranged next to the support frame and, at least, a loose rail, which is movable relative to that, in particular, is removable and insertable.

Other features of the invention are drawn from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features named below in the description of the figures and / or only shown in the figures, are not only usable in the combination indicated in each case, but also in other combinations or separately, without abandoning the scope of the invention.

Next, an embodiment of the invention is explained in more detail by means of schematic drawings. They show:

Figure 1; Y

Figure 3

a schematic section representation in the area of a lane of

guide of the household appliance according to figure 1.

In the figures, the same and equally functioning elements are provided with the same reference symbols.

In the representation according to Figure 1, a cooking oven 1 is shown in a perspective representation, in partially sectioned state, which has a cooking space 2. This cooking space 2 is delimited by a muffle 3, where the muffle 3 has a first side wall 4, a second side wall 5, a base 6, a rear wall 7, and an upper side 8. On the front side, the muffle 3 has a loading opening 9, which is locked by A door not shown. In cooking space 2 food can be introduced for its preparation. Next to an inner side 10 of the left side wall 5 are formed a plurality of guideways 11, 12, 13, as well as 14 and 15. For each track guide 11 to 15, on the opposite side wall 4, next to the Inner side of it, a complementary guideway is formed at the same vertical height level. By means of the paired guideways in each case, the insertion planes are therefore predetermined in the side walls opposite 5 and 4. In the exemplary embodiment, the guide tracks 11 to 15 are configured as one-piece prints on the side wall 5.

In the baking oven 1, a support frame 16 is introduced into the cooking space 2. The support frame 16 is configured as a grid frame, and has a first side rod of the support 17. The support rod 17 has convexities , which extend outwardly and laterally, in the form of fasteners 18 and 19. These convexities in the form of fasteners 18 and 19 are prints on the support rod 17. As can be seen from the representation of Fig. 1, the guide track 13 has in its layout of a lower guide surface 20 a first front sinking 21 and a second rear sinking 22.

As shown in Figure 1, in the incorporated state of the support frame 16 in the cooking space 2, the clamping piece 18 is inserted into the first subsidence 21 and, the second clamping part 19, into the second subsidence 22 Through this, the clamping frame 16 is positioned in the guide rail 13 sunk downwards, in which this is observed in relation to a positioning of the clamping pieces 18 and 19 on the lower guide surface 20, which extends horizontally out of subsidence 21 and 22.

The support frame 16 is configured to position on it a cooking product support not shown in Figure 1, where the cooking product support can be an oven tray, or a roasting pan, or the like.

The support frame 16 also comprises an extraction device, which has a first telescopic extension 23. The telescopic extension 23 installed on the side, left in case of frontal observation, next to the support frame 16, comprises a fixed rail. 24, which is stationary fixed to the support frame 16. Also, the telescopic extraction device 23 comprises a loose rail 25, which is movable forward and backward relative to the support frame 16 and with respect to to the fixed rail 24. If the support frame 16 is inserted into the cooking space 2 according to the representation of Figure 1, then the cooking product support can be seated on the fixed rail 25, and be removed and inserted.

The support frame 16 extends over the entire width (x direction), and is configured, as it is attached to the inner side of the side wall 4, similarly, with a corresponding support rod and two pieces of corresponding support, which engage in corresponding subsidence in a guide notch, that is, guideway.

As it is further recognized from the representation of Figure 1, subsidence 21 and 22 have different conformations and dimensions. The front sinking 21 has flatter cavity paths, while the rear sinking 22 constitutes contours that run steeper and more angular.

In figure 2, a perspective representation of the support frame 16 is shown in this regard. In the context, the opposite support rod 26 with its clamping parts 27 and 28 is also shown. Also on this side another configuration is also configured. telescopic extension 29.

In figure 3, a schematic section representation of a partial section of the side wall 5 with support frame 16 introduced, and cooking product support 30 positioned thereon is shown. In this regard, the guideway 13 is shown. The cooking product holder 30 has a tray-like cavity 31, which is delimited at the upper edge by a surrounding lateral flange 32. The lateral flange 32 is positioned on the loose rail 25. Likewise, it can be seen that the clamping piece 18 is arranged in the collapse 21, where the upper side 33 of the clamping piece 18 protrudes minimally upwards and, therefore, in the direction and, of the vertical level of the height of the lower guide surface 20 outside the subsidence 21. The level of subsidence of the clamping piece 18 and, consequently, of the entire support frame 16 is recognized, as compared to a positioning on this guide surface 20 By means of this subsidence, it is possible to achieve that both the cooking product support 30 which extends with its lateral flange 32 inside the guideway 13, and the support frame 16, can be introduced two in it simultaneously.

Likewise, it is recognized that a height 41, which is sized between the base of the subsidence 21 and an upper guide surface 34 of the guide track 13, is greater than the thickness, or the height 42 of the lateral flange 32 and the height 43 of the clamping piece 18 in the area inside the guide track 13.

On the other hand, a height no longer indicated between the lower guide surface 20, which extends outside a subsidence 21, and the upper guide surface 34, is smaller than these heights 42 and 43 plus the small distance between the side flange 32 and the clamping piece 18, as seen in Figure 3. For the first time by configuring the sinks 21 and 22 in the guide track 13, it can be ensured that both the support frame 16 and the cooking product support 30 applied on it, can be introduced simultaneously in the cooking space 2 and, also, in a guideway 13.

By removing the telescopic extensions 23 and 29, the cooking product support 30 can then be removed first and then the support frame 16 can be removed.

Therefore, by means of such a configuration, it is guaranteed on the one hand that both components, namely the support frame 16 and the cooking product support 30, could be introduced simultaneously, but, on the other hand, also can position, holding itself, the cooking product holder 30 alone and in the guide tracks 11 to 15.

This is especially advantageous precisely for pyrolysis processes, since, in this respect, the support frame 16 should be removed and, for cleaning the cooking product support 30, it should remain only in the cooking space.

However, by means of this modular principle, it is also guaranteed that a removable support frame 16 with telescopic extraction devices 23 and 29 installed can be introduced at any time, and the simplest manageability of the cooking product support is guaranteed. 30 to enter and extract. This is an essential advantage over cooking ovens in which a telescopic extraction device is stationary, for example, fixed to the walls of the muffle.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement Document D01, which can be considered the state of the art closest to the technical object of claim 1 and to which the numerical references that follow, belong, discloses a household appliance for preparing food, in particular cooking oven and cooking oven, with a cooking space delimited through at least one side wall (10), and with a guideway (9) configured next to the inner side of the side wall (10) for housing a support frame (1) for a support of cooking product (13, 15), where the guide track (9) has a lower guide surface that has at least one subsidence (8), into which a fastener ( 3) of the support frame (1), so that the support frame (1) is positioned sunk downwards with respect to a positioning on the lower guide surface outside the subsidence (9) (see figures 9 and 10). Therefore, claim 1 is novel based on what is disclosed in document D01 (Art. 6.1 LP11 / 1986). With respect to dependent claims 3 and 8, the design features described therein are disclosed identically in document D01 (see figures 9 and 10) and, therefore, lack of novelty (Art. 6.1 LP 11/1986). With respect to dependent claims 4 and 9, the design features described therein are simply some of the several obvious possibilities that an expert in the field would select according to the circumstances, without the exercise of inventive activity, to solve the problem posed. Accordingly, claims 4 and 9 do not meet the requirement of inventive activity (Art. 8.1 LP 11/1986). With respect to dependent claims 5 to 7, the design features described therein are considered as mere obvious particular executions for a person skilled in the art and, therefore, lack inventive activity (Art. 8.1 LP 11/1986). With respect to dependent claim 10, document D01 discloses a guideway (9) that is configured in the side wall (10) as a notch. The use of a stamping process for its manufacture is a well known technique and therefore obvious to a person skilled in the art. Therefore, claim 10 lacks inventive activity based on what is disclosed in document D01 (Art. 8.1 LP11 / 1986). With respect to dependent claim 13, the technical characteristics described therein are disclosed identically in document D01 (see figures 13 and 14) and, therefore, is not new (Art. 6.1 LP 11/1986).
