Definitions

• the present invention relates to an oven with a horizontally guided in a furnace muff bracket part for receiving and holding a food support, which is displaceable between a cooking position in the oven muffle and a removal position lying in front of this.
• a generic oven with a holding part guided in an oven muffle and fastened to two horizontally displaceable slides is known from DE 198 25 323 A1.
• the holding part serves to receive and hold food carriers which can be moved between a cooking position in the oven muffle and an at least partially removal position lying in front of the oven muffle.
• the slides are each arranged in an upper area of the furnace muffle, near an upper heat.
• An object of the invention is to further improve an oven according to the preamble of claim 1 with regard to the stability and the compactness of the horizontal guide.
• this goal is achieved with an oven according to the preamble of patent claim 1 by two holding elements which are displaceably guided on opposite side walls of the oven muffle and are each spaced apart from an upper side and an underside of the oven muffle. Due to the arrangement of the holding element or its guides spaced from the upper and lower heating elements of the furnace muffle, the surface available for the heating elements of the top heat and the bottom heat in the furnace muffle is not impaired by guide elements arranged in the vicinity thereof. Rather, almost the entire width of the furnace muffle is available for the arrangement of the upper and lower heating elements. In addition, the approximately centrally arranged holding element is subject to a lower bending moment when a food support is suspended in an uppermost or a lowermost insertion position.
• each holding element comprises at least one horizontally displaceable slide for the horizontal guidance of a cooking deposit surface.
• Each of the two slides is preferably arranged in a central region on the side wall of the furnace muffle.
• the holding element comprises a hook rail which is guided and suspended on the slide.
• the two hook rails preferably each extend vertically, so that their longitudinal extension directions are each arranged perpendicular to the direction of extension.
• the length of the hook rails is expediently slightly less than the height of the furnace muffle.
• the two hook rails are coupled to one another with a rigid cross strut or cross connection, so that one of the two hook rails cannot be accidentally moved backwards when a food support is hooked in and must be manually pulled forward again.
• a latching position of the slide can expediently be provided. In this way, the food support can be easily hooked into the hook rail and then pushed into the cooking position by light pressure to overcome the catch.
• Such a locking position can advantageously also be provided in a cooking position.
• Rolling bearings are particularly suitable as bearings for the slides. These bearings can either have grease lubrication or run dry. Rolling elements and / or raceways made of ceramic or with a ceramic coating are particularly suitable for this. Dry roller bearings of this type are particularly suitable for pyrolysis operation of the oven, since temperatures of up to 500 ° C. are reached, which conventional grease lubrication of roller bearings would not be able to withstand.
• a further preferred embodiment of the invention provides electrical insulation of the slides and the hook rails from the oven and from the oven muffle, thereby it becomes microwave-safe.
• the electrical insulation prevents sparking or high voltage flashover on electrical parts in the furnace muffle. Electrical insulation can be achieved, for example, by the rolling elements being made of electrically insulating ceramic or the like.
• FIG. 1 shows a schematic perspective illustration of an oven muffle with a holding part located in the cooking position
• FIG. 2 shows a perspective schematic representation of the oven muffle with the holding part located in the removal position and the food support suspended therein,
• FIGS. 3 and 4 show a first variant of a slide guide of the holding element in two views or sectional views
• FIGS. 5 and 6 show a second variant of the slide guide in two views or sectional views
• FIG. 7 shows two hook rails coupled to one another by a cross strut in a perspective view
• FIG. 8 shows a schematic illustration of a device for locking the slide in preferred positions.
• FIG. 1 shows an oven muffle 2 of an oven in a perspective and schematic representation.
• An oven door 5 which is in the closed position against a front frame 4 and closes the oven muffle 2 at the front is in the open, pivoted position horizontally to the bottom.
• a holding part 1 2 according to the invention for supporting and guiding a food support comprises two holding elements 13 which, in the exemplary embodiment shown, have two hook rails 14, which are each guided horizontally displaceably on a guide rail 18 on side walls 6 of the oven muffle.
• a carriage 16 can be placed on each of the two guide rails 18 in slide horizontally.
• a nj edem sled 1 6 is a hook rail 1 4 rigidly attached.
• the hook rails 14 which consist of narrow, elongated sheet metal strips, have a longitudinal direction perpendicular to the pull-out direction and parallel to the side walls 6.
• the hook rails 14 are preferably each at a relatively small distance from an upper side 10 and from a bottom surface 8 of the oven muffle 2, so that the food supports can be arranged close to or away from the top or bottom heat as required.
• the guide rails 18 expediently extend over approximately the same length, which corresponds to a depth of the furnace muffle 2. In this way, the slides 16 with the hook rails 14 attached to them can be moved approximately over the entire depth of the furnace muffle 2.
• the guide rails 18 are each arranged in a central region of the side walls 6, so that the guide rail 18 and the slide 1 6 and the hook rail 1 4 fastened thereon do not adversely affect heating elements of an upper or lower heat.
• the maximum bending moment on the hook rails 14 when hanging a food support in a lower insertion position is significantly reduced.
• the holder part 12 can be significantly more compact with the same stability.
• each hook rail 14 has five grooves 22 spaced apart from one another, each of which defines an insertion height for a food support.
• they can each have an indentation along their longitudinal direction, which can increase their bending stiffness and can thus prevent contact with the side walls 6, even if several food supports with correspondingly high loads are attached.
• FIG. 2 shows the hook rails 14 in a front removal position, in which both carriages 16 with the hook rails 14 attached to them are each on a front stand near the front frame 4.
• a food support 24 is hooked into the corresponding grooves 22 from below in a second position.
• a further development of the holder part 12 according to the invention can lie in a combination with telescopic pull-outs. In this way, a so-called full extension can be realized, in which the food support 24 can be pulled out into a position in front of the front frame 4.
• the exemplary embodiment shown with the rail pull-out allows only a partial pull-out in which a rear edge of the food support 24 in the removal position is still inside the oven muffle 2.
• FIG. 3 shows a first variant of guiding the carriage 16 on the guide rail 18.
• two rolling elements 20 are rotatably mounted.
• a rolling element 20 slides on an upper side or on an upper edge of the guide rail 18.
• the other rolling element 20 slides on an underside or on a lower edge of the guide rail 18.
• the arrangement shown in FIG. 3 is also due to the weight exerted by the food support
• One rolling element 20 above and one below the guide rail 18 is sufficient.
• the rolling elements 20 are arranged offset with respect to one another in the slide 16, so that by tilting the slide 16 the slide 16 can optionally be detached from the guide rail 18 and removed.
• the weight moment exerted by a food support, which stabilizes the slide 16, is indicated by an arrow.
• two rolling elements can be provided at the bottom and / or at the bottom, as shown in FIG. 5.
• FIG. 4 shows a sectional illustration of a holding element 13 of the holding part 12 in a viewing direction parallel to the pull-out direction of the slide 16.
• the guide rail 18 is firmly anchored in the side wall 6 and has a vertical guide section with rounded upper and lower edges, which simultaneously act on the running surfaces form for the rolling elements 20.
• the rolling elements 20 are shown in the embodiment shown.
• the hook rail 14 is rigidly fastened.
• FIGS. 5 and 6 show in two views or partial sections an alternative embodiment of the holding element 12 according to the invention, in which four roller bodies 20 are rotatably mounted in each slide 16.
• two spaced-apart rolling elements 20 slide on the upper and on the lower edge of the guide rail 18.
• This has a front stop 34 and a rear stop 36, against which the slide 16 can abut.
• the stops 34, 36 define the maximum path that the carriage 16 can travel on the guide rail 18.
• the guide rail 18 is anchored to the side wall via a plurality of fastening points 38.
• Figure 5 illustrates an offset assembly of the hook rail 14 on the carriage 16 so that it is moved closer to the front frame of the furnace muffle in the removal position. This may make it easier to hang up and remove the food support.
• the slide 16 has a bowl-shaped contour with the rolling elements 20 suspended on one side.
• the hook rail 14 is fastened to the closed side of the slide 16, while the open side faces the side wall 6 of the furnace muffle.
• the carriage 16 largely engages around the guide rail 18, so that overall a very compact and space-saving unit is formed.
• the rolling elements in the second variant are designed as symmetrical double cones, each with blunt end faces, the central edge of which slides in a correspondingly trench-shaped track of the guide rail.
• This alternative design of the slide and the guide rail is characterized by particular compactness.
• the holding part 12 with the two holding elements 13 can be made particularly narrow and space-saving in this way, so that the overall width of the furnace muffle is hardly enlarged compared to a furnace muffle provided with conventional inserts. Possibly.
• the guide rail placed on the side walls 6 of the furnace muffle 2 can also be countersunk in a corresponding recess, so that essentially only the hook rail is at a short distance from the side wall 6 the oven muffle protrudes from the side outline. In this way, a further reduction in the overall width of the furnace muffle can be achieved.
• FIG. 6 shows a food support 24 suspended in grooves 22, which is located in a middle insertion position approximately at the level of the guide rail 18.
• FIG. 7 shows a perspective view of a preferred embodiment of the holding part 12, in which the two hook rails 14 are connected to one another by a connecting strut 26. In this way, it can be avoided that one of the hook rails 14 is accidentally pushed backwards when the food support is hooked in.
• FIG. 8 shows a possible embodiment of a locking device 27, which consists of a spring-loaded ball 30, which can snap into a recess 32 in the guide rail 18.
• the ball 30 is preferably held in the carriage and can engage in a recess 32 located in the front region of the guide rail 18 and thus defining a detent in the removal position.
• a further recess can be provided in a rear region of the guide rail 18, which defines a further latching position in the cooking position of the food support.
• the locking positions preferably correspond to the corresponding stops of the slide (see FIG. 6), so that in practice the maximum displacement of the holding element is used.
• roller bearing of the slide shown cannot have conventional grease lubrication.
• roller pairs made of ceramic or with a ceramic coating are particularly suitable.
• Such a pair of rollers also has the further advantage that the holding part 12 can be electrically insulated from the furnace muffle. This enables the oven to be used in a microwave oven, since there is no risk of spark and high voltage flashovers due to the insulation of the holding element.
• the material for the guide rails, the slides and the hook rails comes in question, for example, aluminum, stainless steel or brass, which may have a ceramic coating on the guide rail.
