Description

The invention relates to a muffle oven.

In the simplest case, food carriers are accommodated in grooves in the muffle walls or between bars of supporting grids which are attached to the muffle walls. In this way, the user can grasp the front of the food support and either slide it into the oven muffle for cooking or pull it out of the oven oven to remove or examine the food. However, there is a risk of tipping and scalding with food. One tries to counter this by baking trolleys that hold the food carriers on a horizontally movable door or can be moved separately between a cooking position in the oven muffle and a change position in front of the oven muffle. On the other hand, pull-out systems are offered, the movable rails of which support the food carriers. In the case of the baking trolleys, all of the food carriers are moved at once. In the case of the pull-out systems, the user can only grasp the food carriers from the front.

A baking trolley guided on the side rails in the lower muffle area according to DE 79 17 197 U1 picks up the food carriers in levels above the rail level, in the two lower levels on their entire opposite long sides, in the upper level on the rear half of their long sides. It is driven by a rotary lever that runs in a backdrop that extends upwards from the rail level. From DE-GM 75 05 695 a baking and roasting tube is known, in which a baking and roasting product carrier also guided in the lower area on the side rails has two profile carriers which extend upwards from the rail level and to which short wire clips are provided in different planes Inclusion of slide-in parts, such as pans or sheets, are arranged. The DE 198 25 323 A1 describes an oven with a carriage guided in the upper area for a holding part which extends downward from the rail level and which has short hook rails in different planes for receiving food carriers. The DE 198 47 727 C2 finally shows telescopic pull-out devices, which are arranged in different levels in order to receive food items on their movable slide rails and to move them independently of one another.

In the ES 1 011 203 U describes a baking oven muffle with a holding device in which the food support can be hung in several levels from behind. The holding device is displaceable between a rear and front position. In the front position, the food carriers can be exchanged, the holding device being in the front position behind the loading opening.

From the US 2,130,168 a cooking oven muffle is known in which the food support can be inserted in several levels. In addition, the food carriers can be hung in a holding device. The Holding device is displaceable between a rear and front position, the holding device being in the front position behind the loading opening.

In the DE 89 15 017 U1 describes a baking oven muffle with a holding device in which the food support can be hung in several levels from behind. The holding device is displaceable between a rear and front position, the holding device being in the front position behind the loading opening.

From the DE 42 36 740 A1 a muffle with a holding device is known, in which the food support can be hung in several levels from behind. The holding device is displaceable and pivotable between a rear and front position, the holding device being located in the front position behind the loading opening.

In the EP 0 811 807 A2 describes a baking oven muffle with a holding device in which the food support can be hung in several levels from behind. The holding device is pivotable between a rear and front position, the holding device being in the front position behind the loading opening.

From the DE 75 05 695 U a muffle with a holding device is known, in which the food support can be hung in several levels from behind. The holding device is displaceable between a rear and front position, the holding device being in the front position behind the loading opening.

In the AT 381 622 B describes a baking oven muffle with a holding device in which the food support can be hung in several levels from behind. The holding device is pivotable between a rear and front position by means of a lever mechanism.

The oven muffle 2 which can be closed with a door (not shown) has two opposite walls 4, a bottom 6, a ceiling 8, a rear wall 10 and a front opening 12.

Each of the walls 4 carries on the inside a removable wall-parallel support plate 14 which extends through the wall, the ceiling, the floor and / or the rear wall at least at one point in order to trigger a presence detector there, for example. At least one of the two support plates 14 is mounted to the wall with play. On the opposite support plates 14 are according to the Figures 1 and 2nd two telescopic pull-outs 16 each fastened one above the other, which can be tilted exactly horizontally or slightly forward and, if necessary, detachably. The double pull-outs 16 each consist of an immovable rail 18 fastened to the support plate 14, a rail 20 displaceable thereon, a rail 22 immovable thereon and a rail 24 displaceable thereon. Slideways and / or roller guides such as ball or roller guides can be used for this.

On each of the rails 24, a holding device 26 is attached immovably and preferably removably at the same position. Although not absolutely necessary, opposing holding devices 26 are by a cross bar 28, which gives additional stability.

The holding devices 26 according to Fig. 1 and 2nd can each hold two food supports 30. For this purpose, they each have a horizontal section 32, onto which the food support 30 can be pushed with its rear bottom region 34, a horizontal section 38 arranged above section 32 to form a gap 36, to which an upwardly extending projection 40 of the rear section can create the upper edge area 42 of the food support 30 to secure its horizontal position, and a hook-like section 44 which engages in a recess 46 arranged behind the projection 40 of the rear upper edge area 48 of the food support 30 in order to pull it horizontally out of the holding device 26 to prevent. Section 32 is followed by an obliquely outwardly directed section 50, which serves as a lateral guide aid.

The levels in which the sections form shaped elements for receiving the items to be cooked are selected such that even with only two pairs of holding devices which can be moved independently of one another, each of the baking space levels recommended individually or in combination are available, for example baking space levels 1, 3, 4 and 1 and 4th

At least one holding device 26 of each level can be assigned at least one unlocking element, not shown, and one spring element, not shown, which relaxes after unlocking the retracted holding device 26 and presses it outward to support it.

The mode of action is as follows:
If there are two food supports 30 in the oven muffle 2, one of which has to be pulled out to check the food not shown, the holding device that carries the food support must first be unlocked, if possible, so that the holding device 26 at least together with the rails 24 moves automatically at least in sections in the direction of the front opening 12 and brings the food support 30 in front of the oven muffle 2 at least in sections. If there is no spring element including a lock or the holding device is not fully extended, the user grips the food support 30 and pulls it out on the double pull-outs 16 itself.

As soon as the food support 30 looks out of the oven muffle 2, the user can grasp it not only from the front, but also from the sides, which is of great value in particular if the food support is to be removed (for example after it has been completely removed). For this purpose, the food support 30 is tilted slightly upward, so that the hook-like sections 44 of the holding devices 26 come out of the recesses 46 of the rear upper edge areas 48 of the food support, and then pulled forward. Conversely, the food support 30 is inserted between the lateral guide sections 50 from obliquely above into the gaps 36 of the holding devices 26 and placed on their horizontal sections 32 and finally pushed backwards until the recesses 46 are below the hook-like sections 44. Then you move the food support downwards until it rests with its underside on the horizontal sections 32, with its back Above extending projections 40 abuts the horizontal portions 38 and has received the hook-like portions 44 with its recesses 46.

According to an embodiment, not shown, the holding devices are themselves slidably received on the movable rails, so that rail sections below the food support, even if they are spaced from it, are completely eliminated.

According to the Figures 3 and 4th Three pairs of double pull-outs 16 are distributed on the supports 14 arranged on opposite walls 4, the floor 6 and the ceiling 8 of the oven muffle, each double pull-out 16 carrying a holding device 26 and two holding devices on one level being connected by a crosspiece 28. However, in addition to a holding device 26, which can each hold two food carriers 30, two holding devices 26 are also provided, which are designed to hold only one food carrier 30 and have a receiving plane arranged above the rail level, but which are also below the rail level or in the rail level could, for example, if the holding device is slidably received on the rails.

Holding devices 26 with only one receptacle for only one food support 30 can easily be integrated into telescopic systems made of rails that can be pushed together and / or into one another due to their dimensions. So the last one movable rail can be designed, for example, directly for exchangeable accommodation of a food support from the rear and / or from the sides.

Both versions can be according to the Figures 5 and 6 on the lowest movable rails 24, carry a horizontal plate 52, for example made of glass or glass ceramic, between a grill area, which is located above a grill heater 54 arranged above the floor 6, and a loading area, which is at least partially in front of the oven muffle 2 , is movable. However, such a grill plate can also be arranged on the lowermost movable rails 20 or on the lowermost holding device 26. In addition, it is possible to attach such a grill plate 52 to a separate rail system 56, which does not have a holding device 26.

In the Fig. 7 and 8th A muffle is shown in which the support plates 14 carry individual pull-outs 58 made of a rail 60 which is immovable on the support plate 14 and a movable rail 62 which receives the holding device (26).

9 to 18 show a oven muffle 64, in which the double pull-outs are not arranged on supports 14 which hang on the walls 4 of the oven muffle, but on a support 66 which stands on the bottom 6 of the oven muffle 64. In the event that a bottom heating element is located above the bottom 6 of the oven muffle 64, the carrier 66 is designed as a horizontal frame which surrounds the bottom heating element and, if appropriate, projects above it. Regardless, points the carrier 66 has on its opposite sides two wall-parallel flat sections 68, the inner sides of which carry the fixed inner rails 18 of the double pull-outs 16 (or of single pull-outs).

According to the Figures 9 to 11 is attached to the mutually facing inner sides of the movable outer rails 24 of the double pull-outs 16 (or of single pull-outs) a lower part 70 carrying the holding devices (holding combs), which here as a horizontal frame with wall-parallel flat sections 72 for rail fastening and a circumferential support 74 for Horizontal recording of a plate 76 is formed, which consist of glass, glass ceramic, ceramic and stone or the like. Or also made of metal and, for example, in the retracted state of the cover of a bottom heat radiator arranged above the floor and optionally the inclusion of food to be cooked, in particular grilled Food to be cooked and / or can be used by food carriers.

According to the Figures 12 to 18 can be placed on the outer movable rails 24 of the double pull-out 16 (or single pull-out), a lower part 78 carrying the holding devices 26, preferably immovably (but possibly also displaceably), here as a horizontal frame with contact surfaces 80 for resting on the top of the rails 24 and one Circumferential support 74 already described is designed to receive a plate 76 already described. The immovability of the lower part 78 with respect to the rails 24 is realized by recesses 82 in the support surfaces 80, into which elevations 84 of the rails 24 engage from below.

The lower part 78 is made of a sheet metal, on the flat or frame-like central horizontal region 86 of which on both sides and parallel to each other in sequence upward vertical sections 88, outward horizontal sections 90 and downward vertical sections 92 are connected together form U-shaped cross sections which are closed towards the front, that is to say towards the user, by vertical and interconnected sheet metal sections 94. This cover protects when retracted ( Fig. 12 and 13 ) the pull-outs (here double pull-outs 16) and in the extended state ( Fig. 14 ) at least the outer, most extensible rails (here rails 24) in front of splashing food.

The holding devices 26 have, at their lower ends, bends pointing away from the walls 4 with horizontal sections 96 which can be placed on the sections 90 of the lower part 78 and vertical sections 98 which can be placed on the sections 88 of the lower part 78.

The carrier 66 is made from a sheet metal, from the flat or frame-like central region 100 of which the flat wall-parallel sections 68 extend on both sides on the one hand, in order to accommodate the fixed rails 18 of the pull-outs 16 at least substantially horizontally on their mutually facing inner sides, for example also slightly inclined forward, and on the other hand, a section 102 extends down the rear wall parallel to the front side, for example to cover a bottom heat radiator arranged above the floor 6 to the front. Finally, too on the back, a section 104 extends parallel to the rear wall obliquely upwards, to which a possibly further, narrower section 106 adjoins vertically upwards in order to hang the carrier behind the rear wall 10. Alternatively, this is also possible by means of a separate component 108 arranged on the carrier 66, which also extends obliquely backwards in a first section, horizontally backwards in a second section and vertically upwards in a third section ( Fig. 15 ). The carrier carries 66 feet or runners 110 on its underside.

Alternatively, both the carrier and the lower part can be made from die-cast aluminum.

The mode of action, if not already described, is as follows:
In the cooking mode, the carriage can be moved out of the lower part 70 or 78, holding parts 26 and double pull-outs 16 or their rails 24 out of the oven muffle 64 or into these by pulling or pushing on the lower part 78 which is connected to the rails 24 in a non-displaceable manner, so that the rails 24 with the lower part 70 or 78 and the holding devices 26 arranged thereon move with respect to the rails 22 and the rails 20 fixedly connected to the rails 22 with respect to the rails 18 firmly connected to the carrier 66. Alternatively or in addition, the rails can also be unlocked with respect to a spring that is pretensioned during insertion.

Before pyrolysis operation or for the purpose of conventional cleaning of the oven muffle 64 and / or the conventional or dishwasher cleaning of the lower part 70 or 78 and / or the holding devices 26 and / or the carrier 66, the user can remove the holding parts (holding combs) 26 from the lower part 70 or 78 and / or remove the lower part 70 or 78 with or without holding parts 26 from the carrier 66 and / or remove the carrier 66 with or without a lower part 70 or 78 and / or holding devices 26 from the oven muffle 64. The easiest way is, of course, if the lower part (78), as in the Figures 12 to 18 shown, only rests on the rails 24 of the double pull-outs 16 (or single pull-outs) and not, as in FIGS Figures 9 to 11 shown, is connected (laterally) to the extracts.

In order to be able to remove the carrier 66, it must first be tilted slightly upwards on the front side until its rear sections 108 and 106 slide out of the recess in the rear wall 10.

The equipment in the oven muffle 64 is carried out in the reverse order in that, in a first step, the rear sections 108 and 106 are first inserted into the recesses in the rear wall 10 by lifting the support 66 at the front and brought behind the rear wall 10 by subsequent lowering of the support 66 and in a second step, the lower part 70 or 78 is placed against the rear, upwardly directed tabs of the rails 24 and is placed on the rails 24 in such a way that their elevations 84 engage the recesses of the lower part 70 and 78 from below.

Correspondingly, the muffle 2 according to the Figures 1 to 8 remove the holding devices 26 from the rails 24 and / or remove them from the support plates 14 and / or remove them from the walls 4. Like the support plates 14, the supports 66 of the oven muffle 64 can pass through the walls 4 and / or the floor 6 and / or the rear wall 10 in order to trigger presence detectors. Both the support plates 14 and the carriers 66 can be assigned latching means, not shown, which cooperate with latching means of the oven muffle 2 or 64, in order to detach the support plates 14 from the walls 4 of the oven muffle 2 or tilt the carrier 66 out of the oven muffle 64 to prevent.

According to the Figures 19 to 21 a lower part 78 is provided that cannot be placed on from above, but can be pushed onto the movable rails 24 from the front. For this purpose, the lower part 78 has on its vertical sections 88 outwardly directed horizontal supports L, which are designed here as a horizontal leg of an angle plate W, and the rails 24 on their mutually facing inner sides inwardly directed and in particular pocket-shaped features P which are open upwards and downwards on. In the horizontal cover surfaces 90 of the lower part 78, slots S extend in the direction of movement of the rails 24, which, when pushed open, are aligned with the vertical pockets T of the forms P. Slits S 'also extend in the frame-like region 86 of the lower part 78, but transversely to the direction of movement. The holding devices 26 have, in addition to first vertical sections VA1, which extend essentially in the direction of movement and receive the food carriers in several planes, second vertical sections VA2, which extend from to extend the rear sides of the first sections VA1 transversely to the direction of movement towards one another. Tabs LA1 are formed at the lower ends of the vertical sections VA1, and corresponding tabs LA2 are formed at the lower ends of the vertical sections VA2.

The mode of action, if not already shown, is as follows:
The lower part 78 is pushed onto the inserted rails 24 of the carrier 66 from the front, so that its horizontal sections 90 come to rest from above on the upper sides of the rails 24 and its supports L from below against the features P of the rails 24, whereby a positive fit occurs between the lower part 78 and the rails 24. If the rear edges of the lower part 78 abut the upward-facing tabs of the rails 24, the holding devices 26 are from above, on the one hand, with their tabs LA1 through the slots S of the lower part 78 and the pockets T of the rails 24, and on the other hand with the Tabs LA2 inserted through the slots S 'of the lower part 78. After the lower part 78 is connected to the rails 24 and the holding devices 26 both to the lower part 78 and to the rails 24, the unit comprising the carrier 66, lower part 78 and holding devices 26 is placed on the bottom 6 of the oven muffle 64 and with the Sections 104 and 106 suspended in the manner described above in the rear wall 10.
If one now wishes to equip the holding devices 26 with food carriers 30 in a manner also described above, the lower part connected to the movable rails 24 is pulled 78 out of the oven muffle 64 with respect to the other rails.

Finally, according to 22a to 22c and 23a to 23c a carrier 112 can also be provided, which can also be placed on the floor 6, but instead of pull-out systems in a ( Fig. 22 ) or several levels ( Fig. 23 ) has one or more horizontal raceways 114, on which one or more holding devices 118 equipped with rollers 116 can roll out of the furnace muffle or roll into the latter. A pair of opposing raceways 114 is provided for each level, which extend obliquely upwards with respect to one another and each lead two pairs of rollers 166 arranged one above the other with inclined running surfaces. The rollers 116 running at the top and bottom of the raceways 114 consist entirely or on their running surfaces of elastic material, preferably of rubber or high-temperature plastic. The holding devices 118 located opposite each level can be moved independently of one another and, for example, can only be connected to one another by the food support 30. However, they can also be connected by webs or surfaces which have cooling air openings, for example. With the holding devices 118 according to Fig. 22 and that of the upper level of FIG. 20, four food carriers can be received in levels lying one above the other, with the holding device 118 of the lower level Fig. 23 only one.

The supports 66 and 112 can be assigned separately or in the form of the design of the feet, not shown, shaped elements and / or latching means which are provided with shaped elements, for example embossings, and / or locking means of the oven muffle 64, for example the base 6, cooperate to secure a predetermined installation position.

Overall, a muffle is thus available which has holding devices for items to be cooked which can be variably arranged and / or moved independently of one another and which, in particular, are easy to retrofit.
