Baking and roasting device

The invention relates to a baking and roasting device with electrical resistance heating and rotatable skewers.

Such household appliances are known in various embodiments, wherein the fixed or movable arranged food is exposed to infrared rays from any source which is connected to a Screen or reflector can be equipped to improve the radiation effect. These devices are generally cuboid and usually have a removable bottom and a pan as well as several side notches or incisions into which you can

For example, arrange a grate or a skewer at different heights can. The electrical resistors are arranged either at the top in the lid or at the bottom of the device and heat directly or the food on the skewers via a heated floor impaled or placed on the grating.

Devices of this type can either be used as a normal roasting oven, in which case one of the side surfaces is open. But you can can also be used as an oven, with heating then taking place from the floor and all side surfaces being closed.

As soon as such devices are used as a roasting oven, one takes place Rotation of the food by using a suitable device to rotate the skewer on which the food is skewered is moved. It is also possible to use a plurality of skewers for example to be arranged on the circumference of a rotatable drum, in which case the skewers themselves rotate in the opposite direction be moved.

However, these known devices have various disadvantages. So are For example, the heating devices are generally formed from a series of several resistors which are shaped in a certain way. Here

1 0 9 8 A 1 / Π S 5 3

however, each element is separate from the other and it exists here a certain space between the individual elements. To this Way there is a loss of heat, which can be considerable if the device is used as a roasting oven and one of its side surfaces is open.

Due to the versatility of these devices, for example as an oven with permanently arranged baked goods or as a roasting oven with movable roasting goods, it is necessary to convert a number of elements each time, which is sometimes associated with certain difficulties in the household. It is particularly necessary to use such a device during the conversion from an oven to a roasting oven to provide the open side wall with a translucent or transparent screen. In some In some cases, it is even necessary to dismantle the heating elements and reinstall them in another location, which is particularly important in this case Difficulties when they are still hot.

Furthermore, the devices for rotating the skewers are in general differently designed, depending on whether it is a skewer with a single roast or with a number of skewers with a smaller one Food to be roasted. In this way, the number of manipulations required can be quite significant, even when used as a roasting oven.

The purpose of the present invention is to avoid the above Disadvantages and the creation of a changeable baking and roasting device, which essentially consists of three parts, namely an outer housing, the heating elements and the rotary drive for the Skewers, whereby the special design of these three essential components results in an advantageous combination effect that the previously known Embodiments of such devices do not have.

Such a baking and roasting device with electrical resistance heating and rotatable skewer is characterized according to the invention by a lower bottom part with a rear wall and two side walls and an upper, hood-shaped cover part with a transparent front wall, which at its rear transverse edge on a housing to accommodate the rotary drive and the electrical connection lines are hinged and in the closed state partially overlaps the side walls of the base part.

The cover part can in this case by means of a support in a certain Swivel position can be set and carries the upper radiator, which are held by means of a releasable lock. These, radiators are here arranged to one another in such a way that each radiator is located in the heating area of an adjacent radiator, so that this achieves a maximum heating effect with minimal heating losses.

109841/0553

To increase this heating effect, the upper Radiators a screen or a reflector can be arranged.

The side walls of the lower part are expediently at their upper edges bevelled lengthways and provided with notches to accommodate one or more skewers. The drive of this skewer takes place in a preferred embodiment of the device according to the invention by means of a removable spindle screw which is rotatably mounted parallel to the upper edge of the side wall and which ssen non-rotatably on the skewer seated gears is engaged.

It is also advisable to provide additional lower heating elements. which are removable and can rest on the floor and which can be switched on simultaneously with or separately from the upper radiators are.

In addition, a grill grid is provided, which directly over the

ο lower heating element on the bottom of the device or after swiveling it by 90 can be placed in its plane on the inclined upper edge of the side wall.

Due to the interaction of the features mentioned above, in particular due to the mobility of the upper part of the lid and the possibility of setting it in different positions, the best possible effect can be achieved

109841/0553

the upper radiator can be achieved, creating a major disadvantage of the previously known devices, namely an excessive loss of heating energy, is avoided. In this way, the consumption of electrical energy in the inventive design of a baking and Roasting device compared to known embodiments significantly reduced.

In addition, the device can be used in various "ways thanks to its special design:

For example, the device can be used as an oven when the upper part of the lid is in its lowest position and the food is simply placed on the bottom of the lower part or on a grill grate that is more or less high above the base of the device. The interior of the device in this case is the smallest, so that under the best condi- W g ^un g ^{s w} ith low energy requirements can work. Depending on your needs, the lower or upper heating elements can be switched on or the lower heating element first and then the upper heating element at the end of the baking process in order to give the food a frying layer from its own.

109841/0553

The device can also be used as a roasting oven or grill, for example for roasting steaks or fish, with a grill rack placed on the sloping upper edges of the lower side walls. The upper lid part is then only partially lowered, but the upper heating element as exactly as possible vertically above the food to be fried and at a short distance of these are in order to carry out the actual 'grilling process with good success to be able to.

In the further possibility of using the device according to the invention are used, on which the pieces to be worked are impaled are. This can either be a skewer with a larger piece, e.g. a roast chicken, or several Skewers with smaller meat pieces, which are then in the various notches the upper edge of the side wall. As already mentioned, these skewers carry non-rotatable gears, which with a spindle screw are in engagement, which is set in rotation. The upper cover part is only lowered so far that the heating elements are in a corresponding Away from the food to be fried.

Despite these numerous forms of application and possibilities for change the device according to the invention requires relatively little space, and both during its operation and when not in use. the

Figure 6: a side view of the chassis of the device. j

As shown in Figures 1 and 6, the device includes a chassis
1, the rear part 2 of which is approximately cuboid and accommodates the drive elements for the skewers. The front part 3, which

109841/0553 '

includes part of the bottom 4, has a beveled profile in comparison to the floor.

The lower base part of the device is also beveled on both of its side walls, but in the opposite direction and forms the two upper edges 5 and 5 ¹ . Various notches 6, 7, 8, etc. are provided in these side wall upper edges, which are each arranged in pairs, opposite one another.

The lower space formed in this way is closed by the upper, hood-shaped cover part 9, the lower edge of which is exactly the Line Z-Z 'of the chassis 3 adjusts. This cover part 9 overlaps the upper part of the bottom part 4. At the top of the cover part 9 is also a locking lever 10 arranged, with which the carrier 11 for the electrical heating resistors can be attached or detached. This carrier 11 is in its execution shown in Figures 2 and 2a.

This carrier 11 is provided with a curvature and has a part 12, which cooperates with the mentioned locking lever for fastening the carrier to the upper cover part 9, as well as a shorter part with a curved surface 14 and a bore 15, whereby the Carrier 11 is pivotable about an axis which is firmly seated on the Chassisl.

109841/0553

The three heating resistors 17, 18 and 19 shown in FIG. 1b, the dimensions of which can also be larger or smaller, can be ^{attached to this carrier 11 with their legs 17 'and 17 I (} in any way, for example with screws and nuts 20 and 21. As soon as the electrical resistors 17, 18 and 19 are fastened to the cover part 9 by means of the locking lever 10 and the carrier 11, they can pivot about the axis 16 k , 18 and 19 run without excessive tension in the part 13 of the carrier 11, which is why this is designed in the manner described above.

As a result of the arrangement within the cover part c-j 9, there is a maximum Heat utilization of resistors 17, 18 and 19.

The lower part of the bath of the device can have another one on its bottom take covered heating resistor 23 (Figure la), its shape as desired and which is equipped with two plugs which are inserted into corresponding sockets in the rear housing 2 of the chassis 1. Above this lower resistor 23 can then be arranged a grill grid 26, which can also be replaced by a normal base, the then in turn by the lower Heizwider stood 23 is heated. In the perspective view of Figure 4 is such a grill grid to recognize.

109841/0553

To complete the heating device, the upper heating elements 17, 18 and 19 are provided with a screen or reflector 27, which has the smallest possible surface, but directly perpendicular to it Resistors is arranged in order to avoid any radiation loss upwards and to bring about the greatest possible radiation downwards onto the food to be fried.

In the rear part 2 of the chassis there are also the electrical ones Connection lines the drive devices for the rotatable skewers. These consist essentially of a motor 28 which via gears 29 and 30 (Figure 3) drives a "shaft 31, which in turn transmits its rotation via a coupling 32 to a spindle screw 33, whose The longitudinal axis is arranged in the direction x-x *.

In the illustration in Figure 4a it can be seen how a skewer 34 in a the pair of notches 6, 7, 8 in the lower part 4 is in engagement with a gear 35 or its teeth 36 with the spindle screw 33 in order to also be set in rotation when it is rotated.

Figure 3a shows the arrangement of a single Spiesee 34 on which a Roast chicken 37 is skewered between the upper heating resistors 17, 18 and 19 and optionally the lower heating resistor 23 in rotation

109841/0553

is relocatable, whereby an even heat effect on the entire Surface of the food is achieved.

In particular, FIG. 5 shows a perspective view of the chassis 1 and the bottom part 4 of the device, which is provided with the mentioned pairs of notches 6, 7, 8 ..., within which the spikes 34 are located. The spindle screw 33 is only indicated by the dash-dotted line xx ¹ , from which, however, it can be seen how its rotation also causes the spikes 34 to rotate via the gears 35. With this arrangement, several pieces of meat can be processed on the skewers 34 at the same time.

The cover part 9 is on its front with a transparent disk 38, which closes the open front side 31 (FIG. 5) of the lower part 4 when the cover is lowered into its lowest position. "This disc 38 can be held by a decorative frame 40, whereby

the appearance of the device according to the invention is to be improved. By this disk can then be followed from the outside of the baking or roasting process without the cover part 9 having to be lifted. Even this measure therefore makes a significant contribution to the advantageous use of electrical energy.

1098-1 / Π553

In FIGS. 1 and 4 it can also be seen how the upper cover part 9 more or less overlaps the lower base part 4, which depends on the respective position of this cover part as a function of the baked or roasted food to be processed. The upper cover part 9 is fixed in a desired angular position with respect to the lower base part 4 in any way, for example with a support 41 which can be pivoted behind the disk 38. A handle 42 is also provided on the cover part 9, which makes it easier to lift and adjust the cover and to attach the support. As already mentioned, the cover part 9 rests on the chassis 1 in its lowermost position along the forward inclined line ZZ ^{1 of the part 3.}

The designs described result in numerous possible applications of the device according to the invention without its To fundamentally change the shape, relocate essential parts and in particular without changing the heating resistors. When used as a In the oven, a plate is first placed on the floor or on the grill grid 26, which is then heated from below by the heating resistor 23 can be. The heating effect can be completed from the start by the upper heating resistors 17, 18 and 19. These upper heating resistors can also be switched on alone at the end of the baking process will or remain in order to bring the baking process to an end sooner.

109841/0553

In this form of application, the lower part of the bottom is furthest into the the upper part of the cover entered and the interior of the device »has its smallest value.

When used as a grill apparatus, the grill grate 26 is placed on the inclined upper edges 5 and 5 ^{1 of} the side walls, which run along the line ^ xx ¹ . The upper cover part 9 is here previously folded up by pivoting about the axis 16. This rotational movement is limited by the specially curved surface 14 at the end 13 of the heating resistor support 11. In the same way, this curved surface 14 comes to a stop on the flat part 14 'when the lid part 9 is lowered, whereby the downward movement of the lid is braked before it comes to rest on the chassis 1 along the line ZZ ^1.

After the grill grate 26 obliquely along the line y-y 'on the upper edge of the side wall of the lower part »is placed, the cover part 9 is folded down while pivoting about the axis 16 until the Heizwider stands 17 »18 and 19 are vertically above the food to be grilled. On that then adjusts the aforementioned support 41, which the cover part 9 in the holds the desired position. This precise setting of the lid « parts »9, whereby the upper heat resistance is always perpendicular the Zi grilling foods are located, both with and

109841 / 0SS3

a screen or reflector 27 the best possible heating effect without essential Radiation loss achieved.

To use it for roasting poultry, it is sufficient to place an ordinary pan on the grill rack or some other base, not shown. The poultry 37 (FIG. 3 a) is then impaled on the spit 34, which is then hung into a pair of notches approximately in the middle of the upper edge yy ^{1 of} the lower part 4. As soon as the drive motor is set in motion, the spindle screw 33 rotates this spit with the impaled poultry 37 via the gear 35, which is then evenly exposed from all sides to the radiation from the heating resistors 17, 18 and 19. Here, too, the lower heating resistor 23 can also be used to support the action of heat. Here too, the cover part 9 is folded down and fastened at a height such that the upper heating resistors 17, 18 and 19 are arranged at a suitable distance from the poultry.

The use of the device in the same way for several skewers with smaller pieces have already been mentioned and described in connection with figure.

Further advantages through the inventive design of the baking and Roasting device result from the good accessibility of the parts for a

109841/0553

Cleaning the device and any repairs, as most parts are easy can be assembled and disassembled.
