Description

The invention relates to a griddle with griddle plate provided below NEN heating elements with a surface arranged in a depression or recess of the surface of the griddle.

The term griddle plates or griddle device is a term originating from English that is not translated. What is meant are hot or heatable plates on which the food to be fried is immediately applied is laid. The food can be fried on this surface with or without fat become. Griddle devices are used especially in commercial kitchens, especially in Steakhouses or canteens, in which at the same time a larger amount to be prepared by steaks or other dishes, for which then one on the one hand pans are not enough and on the other hand they are not useful at all are speaking, preferably used.

The griddle plates are on an upper plate or as a surface of accordingly provided relatively expensive griddle devices. The cost factor results derive from the special arrangement and design of the heating elements or those elements that make the heat to be generated as even as possible should transfer to the surface of the griddle. To a simultaneous To ensure that the food to be cooked is ready at every point or at every corner and also in the middle of the griddle the same temperature to rule.

The known griddle plates are in a recess in the surface of the Griddle device inserted. Use any excess when roasting the food The fat collects on the griddle. To better drain the To achieve fat, well-known griddle plates are generally with a clot incline to prefer a certain direction of flow of the grease ben.

To let the fat drain, for example, drainage agents are off Take the griddle device provided. These are often considered lockable  Drain pipe formed. Usually a material is used for the griddle high-temperature steel, especially with a hard chrome-plated surface, or Stainless steel or a sandwich material is used. The problem arises baking of certain fried food on the surface of the griddle. On the one hand this makes the griddle unsightly, on the other hand it leads Soiling from sticking to a commercial damage. That after The following fried or seared food bakes at these points if firm, which leads to deterioration in quality and unpleasant formation of Charring on the fried food can result.

It has therefore proven to be advantageous to coat the griddle plates provision. The lifespan of such a coating is approximately two to four years; the lifespan of the entire griddle, however Multiple of that. This leads to that during the entire lifespan of the griddle device the griddle plates again and again at certain intervals need to be re-coated. However, this subsequent coating is associated with extremely high costs, which is why such a recoating tion is not a portable solution. However, will not be re-coating provided, the wear of the coating later leads to an inadequate quality of the food.

The invention is therefore based on the object of a griddle with a griddle plate to provide, in which the disadvantages no longer occur, so that a constant throughout the life of the griddle quality of the fried food is achieved.

The object is achieved in that a griddle with a griddle plate the preamble of claim 1 is characterized in that a Exchangeable multifunctional attachment for a fitted, non-slip attachment on the griddle plate is provided so that the attachment in the rotating Edge of the indentation or recess of the griddle device inserted non-slip adds. It is also solved by a multi-function attachment that attaches one to one Recess in the griddle adapted shape, a floor surface and a circumferential wall and a means of attack to lift out  from the recess in the griddle. Developments of the invention are defined in the subclaims.

The griddle plate of the griddle device lies in the recess in the surface the griddle. This recess is 1.5 cm deep, for example. To the egg NEN is the recess to prevent the grease from flowing outwards and on the other hand provided that the hot surfaces of the griddle slightly lowered from the general surface as a work surface and thus splashes and the like as a rule within this Area of the recess remain. The recess usually forms with its peripheral edge a rectangle. The Multi is in this rectangle Functional insert removable. His are particularly advantageous Dimensions chosen so that it is within this area of the recess fits non-slip. The slip resistance proves to be very advantageous in the preparation of meals in canteen kitchens where there is a good and instant handling of the devices arrives. By inserting the Attachment in the recess in the griddle device is also a special one Safety aspect fulfilled and safe handling thanks to the all-round guidance within the recess serving as a circumferential guide frame in the created the upper plate of the griddle. For example, one is No advantage with normal movable pans; at the fixed built griddle plates, of course, but also there already disadvantages described.

Lateral grip elements are preferably arranged in any arrangement on the multi Functional attachment provided to take it out of the recess can. This makes it possible to clean the attachment separately, being an automatic dishwasher is particularly advantageous in daily use can be used.

Several attachments are particularly preferred for a griddle device hen, for example, in a steak house or during a working day a canteen can be used in constant change. Because of the light Interchangeability of the multifunctional attachment can quickly change from that  Griddle plate removed and replaced by another attachment. The already used attachments can be stacked in one place or whole melt and be cleaned at the end of the working day. To be particularly advantageous it also turns out to be useful for roasting different dishes, such as Alternating beef steaks and salmon steaks, each with different multifunction to use attachments.

A light, good heat-conducting dimension is particularly preferred for the attachment material used. Here, the use of aluminum or alumini encapsulation, stainless steel or a suitable other metal or metal casting than proven advantageous. By using a light material is a particularly good interchangeability of the multi-function attachment. To the essay lies flat on the still provided griddle plate and due to the good heat-conducting material, it can heat particularly well from the griddle to its own bottom surface of the recess possible.

The attachment is preferably provided with a coating. That’s it advantageously also possible, not only for such a multi-function attachment electrically heated, but also for gas-heated griddle devices. At the known gas-heated griddle plates could not be coated be provided because gas provides too much heat, causing the loading layering is damaged. When attaching the multi-function attachment to the gas-heated griddle but is due to the non-direct contact with the gas flame does not damage the coating of the multi-function attachment. However, the high accuracy that can be achieved with electric heating is in terms of temperature Temperature setting or regulation not available for gas heating.

A range of different multi-function attachments is preferred see, especially of essays with and without drainage to drain grease or the like that collects on the griddle. Dar In addition, attachments with a corrugated or ribbed bottom surface che be provided. Such a corrugated or ribbed surface is used for Griddle plates are usually used to fake a grilled top  area of steaks used. To ensure optimal heat conduction Most, the griddle plate provided under the attachment is preferably flat formed and only the essay on its surface with ribs or the same.

Due to the adaptation of the attachments to the corresponding shapes of Griddle devices and griddle plates can make the attachments particularly advantageous can also be retrofitted to old devices. Such old devices are either already in the market or already in use. A corresponding adjustment of the Multi-function attachments can then be used for all versions of these old devices be advantageously provided.

It also proves to be very advantageous that the griddle plates are optional can be used with or without attachment, as it is not firmly attached to the Griddle is mounted and can be removed as desired.  

In order to explain the invention in more detail, the following are examples games of the invention described with reference to the drawings. These show in:

Fig. 9 is a plan view of a gas-heated griddle with an attachment.

Fig. 1 shows a perspective view of a griddle device 1 in broken representation. The griddle device 1 has an upper plate 10 . In this embodiment variant, the upper plate 10 is shaped in such a way that this upper plate 10 is delimited on both sides by the grooves 11 arranged in parallel. The groove 11 are laterally delimited by an edge plate 12 . The end face 13 of the upper plate 10 of the griddle 1 is flat, a rear plate 14 protrudes above the surface 15 of the upper plate 10 vertically upwards. The rear plate 14 serves as a rear end. The design of the top plate can be formed differently with another type of griddle; it is only intended to serve as an example here.

A recess 16 is formed within the area delimited by the two grooves 11 , the rear sheet 14 and the end face 13 . From the recess 16 is z. B. substantially rectangular with rounded corners in particular 17th A griddle plate 2 is arranged on the bottom surface 18 of the recess 16 , which is not directly visible (since it is covered by the griddle plate).

The griddle plate 2 has a surface 20 . The griddle 2 is heated from the bottom with heating elements, which are not shown in FIG. 1. These are operated electrically, for example, whereby the heating elements can be heated with integrated tubular heating elements. However, it can also be heated by gas, with direct heating using a gas burner system.

Can be added to the griddle plate 2 above the griddle plate, a multi-function attachment 3 . This has such a shape that it can be inserted into the recess 16 from the top plate 10 of the griddle. With its circumferential wall 31 , the multifunctional attachment 3 then bears against the inside of the circumferential edge 19 of the recess 16 or is inserted therein at a distance from it. It is safely stored in the recess 16 slip.

For interchangeable attachment to the griddle plate 2 , the multifunctional attachment has two laterally arranged handle elements 32 .

The multi-function attachment 3 is preferably made of a light, good heat-conducting material. As a result, it is only light in weight, making it easy to replace. By using a good heat-insulating material, the heat generated by the griddle plate on the roast, which is fried on the bottom surface 33 of the attachment 3 , can be passed on. Aluminum is therefore particularly preferred as the material, but also other materials such as stainless steel, cast iron, brass, copper or other metals, or else cast aluminum or another cast metal.

In Fig. 2, a second embodiment of a multi-function attachment 3 according to the invention is shown in a perspective view.

The shape of the attachment 3 is in turn matched to the dimensions of the recess in the upper plate 10 of the griddle device.

The bottom surface 33 lies flat on the surface 20 of the griddle plate 2 .

The attachment has the circumferential wall 31 . This is bent in a radius in the area of its upper edge 34 . As a result, the upper edge of the recess 16 of the griddle device can be overlapped and an undesired penetration of frying fat from the attachment into the recess can be prevented to a certain extent.

If the multifunction article 3 again from the top plate 10 of the rätes Griddlege be removed, 3 of two handle elements 32 are attached for better vulnerability on the attachment. The grip elements 32 preferably have partial elements that can be easily washed off and are made of a non-conductive or poorly heat-conducting material, in particular of wood or plastic, at least in the area of the actual grip part that is touched by the hands. The upstanding from the bottom surface 33 fastening parts of the handle elements are preferably attached to the circumferential wall of the attachment 3 , in particular by welding brazing, screw or rivet connections. However, the handle elements can also be cast directly onto them during the cast production of the attachment, or can also be molded on during manufacture as a pressed part. It proves to be very advantageous to manufacture the handle elements from the same material as the rest of the attachment. An insulating effect with a one-piece construction in particular as a cast or pressed part can be achieved by suitable shaping. In particular, the transition area from the circumferential wall 31 to the grip element 32 is thin and the rest of the grip element is made comparatively thick, as a result of which the thicker manufactured area does not heat up so much that it can no longer be touched or remains relatively cool. Instead of the attachment as shown in FIG. 2, any shaped handle elements 32 can be attached and attached to the multifunctional attachment 3 at any suitable location.

The surface of the bottom of the multifunctional attachment 3 is provided with a coating, as a non-stick coating it is used for better and easier cleaning and a better and more secure against frying of fried food. Teflon or a similar suitable material is selected as the coating here. Since the bottom of the multifunction device according to the invention rests on the griddle plate 2 of the griddle device 1 , but does not come into contact with the heat source directly but only via the griddle plate, both an electrical and a gas heat source can be selected for heating the griddle plate. In the state of the art, the coating is otherwise easily destroyed due to heating with gas which is comparatively hot or the controllability which is therefore not exact.

In Fig. 3 a further embodiment of a multi-function attachment according to the invention is shown in a perspective view. In contrast to the sets shown in the previous figures, the multifunctional attachment has a specially shaped bottom surface 33 . The bottom surface 33 is ribbed. It has ribs 40 arranged parallel to one another. Such rip pen should leave strips on the food to be mimicked, which should mimic a pattern created on a conventional grill.

In addition to and parallel to the ribs 40 , a raised surface can also be formed. It then preferably has a flat surface. Both the ribs 40 and such a raised surface are preferably provided with a coating on their upper side.

A drainage means 50 is arranged in the bottom surface 33 . This is used to run from collecting on the bottom surface 33 frying fat, preferably in connection with a drainage agent of the griddle. The Drainage agent tel has a cover 51 with a grip element 52 . The cover 51 serves that the grease located on the bottom surface 33 can only be drained therein if this is desired, that is to say when the cover 51 is removed from the drainage means 50 . Such a drainage means 50 can, but need not be provided, since the attachment can easily be lifted off the griddle for pouring grease. But even then such a drainage means 50 can facilitate a more targeted emptying of the attachment.

The grip elements 32 of the attachment 3 can take any shape. In the case shown in Fig. 3, they are elements bent from sheet metal.

In FIG. 4 a top view of a further embodiment is a multi-function attachment OF INVENTION to the invention 3 is shown. The dashed lines indicate the wall thickness of the circumferential wall 31 . The two side handle elements 32 are formed as curved metal rods and fastened to the circumferential wall, for example by welding or welding or by means of a nut and screw connection on the inside of the circumferential wall.

FIG. 5 shows the section along the line AA according to FIG. 4. The lateral bent edges 34 of the peripheral wall 31 can be seen particularly clearly in the sectional view.

The sectional view along line BB according to FIG. 4 can be seen in FIG. 6. This view thus represents a sectional view in the longitudinal direction of the attachment according to FIG. 4. This sectional view essentially corresponds to that according to FIG. 5.

In FIG. 7 the edge area of an attachment 3 inserted into the recess 16 of the griddle device 1 is shown enlarged.

A part of the recess 16 is shown with the circumferential wall 19 and Bo denfläche 18th On this floor surface, the griddle 2 is added Darge provides. Below the griddle 2 , heating elements 60 are provided for heating them.

The recess 16 is formed from a folded sheet. The area of this sheet bent by 90 ° from the recess forms the surface 15 of the upper plate 10 of the griddle device. In the edging area of the sheet, the curved upper edge 34 of the multi-function attachment 3 extends from the recess 16 .

The multifunctional attachment 3 has on the underside of its bottom surface 33 a bottom plate 35 which is essentially 100% ground flat. If the multi-function attachment is made in one piece as cast aluminum, formed from an aluminum alloy, the surface is preferably provided with a temperature-resistant Teflon coating and the underside, as shown, ground flat. Such surface grinding serves to enable heat transfer from the heating elements 60 via the griddle plate 2 to the base plate 35 of the multi-function attachment 3, as far as possible without losses or with only minor losses. The base plate 35 should also have very good planicity with only small tolerances.

As an alternative to this, the base plate 35 and the handle elements 32 can be manufactured separately and then connected to the top molding, in particular as a bent metal or aluminum sheet. In terms of production technology, however, this is more complex than a one-piece production, at least with regard to the attachment of the base plate 35 .

In Fig. 7, another shape of the circumferential wall 31 is shown with dashed lines with a projecting handle element as a one-piece molded part element above the curved upper edge 34 . However, the embodiment variant shown could also only be a raised upper edge 34 . This would then leave a larger distance between the upper curved edge 34 and the surface 15 of the upper plate 10 of the griddle device. In such an embodiment, it would not be absolutely necessary to attach additional handle elements to the multifunctional attachment. On such a protruding section of the upper circumferential wall 31 , for example, a corresponding clamping tool can be used and the attachment can be removed from the recess 16 .

As shown in Fig. 7, preferably the outside of the circumferential wall 31 of the multi-function attachment 3 is not directly on the surface of the circumferential edge 19 of the recess 16 of the upper plate 10 of the griddle device 1 . Rather, a distance is left all around, which is, for example, 2 mm. A multifunctional attachment according to the invention for a griddle device can therefore have, for example, a height of 30 μm, a thickness of the base surface with base plate of 5 mm, a length in the region of the base surface of 555 mm and a width of 435 mm. The outer dimensions in the area of the outer extent of the upper edge 34 can then be, for example, 465 mm × 585 mm.

If handle elements 32 are provided on such a multi-function attachment, as shown in FIG. 4, a material thickness of the handle element of 5 mm in diameter can be provided at a distance of 50 mm from the outer edge 34 of the multi-function attachment.

The upper edge 34 , that is to say the bent part, can have a height of 9 mm, for example, and the bottom surface 33 can have a thickness of 3 mm. The base plate 35 would therefore be 2 mm thick. The height of the peripheral wall 31 without bent edge area is then 16 mm.

Fig. 8 shows a plan view of a further embodiment of an inventive multifunctional attachment 3 with layer thickness differences indicated within the base plate 35 . Due to the relatively punctiform or linear distribution of the heating elements, it is necessary to level the heating zones in order to avoid deforming the base plate and surface. Otherwise the base plate and surface may curl. This can be done by means of the multifunctional attachment according to the invention. The bottom surface is not evenly made here, as in the previous embodiments, but is divided into segments of different layer thickness. Even when heated, the desired flatness of the contact surface on the heat source is therefore given. Due to the thermal conductivity of the material used for the attachment, the entire bottom surface of the attachment 3 can be heated uniformly. An uneven searing as in the prior art due to the punctiform or linear heating elements provided under the griddle plate no longer occurs with the multifunctional attachment. The heat zones are thereby equalized.

FIG. 9 shows a top view of an upper plate 10 of a griddle device with gas heating with attached multifunctional attachment according to FIG. 8. The two handle elements 32 of the multi-function attachment are provided so that they do not hinder a fast work even in a large kitchen, but are very suitable for gripping and lifting the multi-function attachment from the recess 16 . The two grip elements are preferably shaped as curved sheets similar to the upper edge 34 of the multifunctional attachment, and are preferably fastened below the upper edge 34 of the attachment.

For gas heating are in the area of the rear plate 14 of the upper plate 10 of the griddle oblong slots 70 hen hen for the exhaust gas removal.

In order to enable a good drain in the direction of the drain means 50 according to FIG. 3, the bottom surface 33 and / or base plate 35 of the set 3 can also be provided with an inclination in the direction of the drain means 50 . Such an inclination can also be generated in that, for example, in the area of the rear plate 14 of the upper plate 10 of the griddle device, as shown in FIG. 1, a depth of the recess of z. B. 30, in the region of the end face a depth of 13 mm z. B. 32.5 mm is provided. The length of the recess 16 can be 560 mm, for example. Since a suitable for fat drainage inclination of the bottom surface of the set 3 is created. The drainage means 50 is preferably seen at the point at which a corresponding drain is also arranged on the upper plate 10 of the griddle device. As a result, only one cover 51 of the attachment 3 needs to be opened, but not any corresponding cover of the sequence arranged on the upper plate 10 of the griddle device.

Due to the good adaptation to the shape of the upper plate 10 of a griddle device, old devices already on the market or used for years can be retrofitted with the multifunctional attachment. In its shape, its dimensions and its material, the multi-function attachment can therefore be optimally adapted to the conditions of the griddle device for which it is to be used. Preferably, a whole assortment of differently made multi-function attachments is provided for a griddle, for example for alternately roasting different types of food.
