Abstract

The invention relates to a cooking appliance (1) with a plurality of guides (22) for guiding food carriers (40), in particular baking trays, the guides (22) being arranged on the side walls (15) of the cooking appliance muffle (10). The direction of extension of the guides (22) drops at an angle of inclination (α) of at least 1 ° with respect to the horizontal from the muffle opening (11) to the interior of the cooking appliance (12).

Description

The invention relates to a cooking appliance according to the preamble of claim 1.

In cooking appliances baking trays are added to bring in several levels one above the other cooking food in the cooking appliance muffle. When fitting the baking tray this is pulled out of the cooking appliance. For this purpose, guides are arranged on the side walls of the cooking appliance muffle. In a far out of the oven state, the baking tray is held only at its rear area. Thus, the weight of the food causes a bending moment, which causes the front end of the sheet to tilt downwards. If the skew angle is too large, so there is a risk that the food falls slipping forward from the baking sheet. According to the standard IEC 60335-2-6 is the maximum permissible skew angle 6 °. In order to keep the skew angle low, it is known to keep the game in the guides as small as possible. On the other hand, materials with high rigidity or correspondingly high material thickness are used in order to minimize the elastic deformations, and thus the tilt angle, under the loads.

Object of the present invention is to provide a cooking appliance with food supports, in which the maximum allowable tilt angle is maintained and is easy and inexpensive to manufacture.

This object is solved by the features of claim 1.

Inventively, a cooking appliance is provided with a plurality of guides for guiding food supports, in particular baking trays, wherein the guides are arranged on the side walls of the cooking appliance muffle. In this case, the extension direction of the guides at an angle of inclination of at least 1 ° relative to the horizontal from the muffle opening to the cooking appliance interior sloping. Since the inclination angle of the guides opposite to the resulting skew angle of the food support in the extended position, or outer end position, acts, is reduced by the inclination angle of the skew angle, which reduces the risk of slipping down of food to be cooked.

In particular, an insert carrier with a plurality of guides is arranged on the side walls. Compared with embossing the guides in the side wall of the muffle, the insert carrier offers the advantage of more accurate guidance with tighter tolerances. With the help of the insert carrier, a substantially parallel slot for receiving a leading edge of the baking sheet can be created, whereas such a form can be achieved only with great effort formative. At attachment points (such as punched openings), the insert carrier is attached to the muffle side wall. The angle of inclination can be achieved simply by the "twisted" positioning of the attachment points on the side wall, which causes no special costs in production and thus is significantly less expensive than a mechanically / elastically stiffer design of the baking sheet and its leadership.

In addition, the insert carrier has a frame element connecting the guides, which is aligned perpendicular to the extension direction of the guides. This ensures that the insert carrier itself does not produce the inclination angle, or has, but this results from a slightly twisted attachment of the insert carrier on the side wall. This means that in each case an identical insert carrier can be used on the left and right side wall of the muffle, which reduces the item costs and simplifies assembly.

Alternatively, the guides may be embodied as embossments in the side walls of the cooking appliance muffle. This is a cost effective option since no separate insert carrier is needed here.

In addition, the angle of inclination is less than 6 °, since at a greater angle of inclination there would be the danger that food would slide from the baking sheet in the fully inserted position of the baking sheet in the oven to the rear. This slippage could be caused both by the inclination angle itself, as well as by the remaining pulse of the food during braking of the baking tray when reaching the retracted position.

In particular, the insert carrier has two wire clips as a frame and the guides of the food supports are each designed as two parallel longitudinal struts. This simple construction reduces the component costs and the mass of the insert carrier can be kept low, which improves the heating speed of the cooking appliance.

Alternatively, the guides of the insert carrier are designed as telescopic bearings, which has the advantage that the baking tray can be pulled to 100% or more out of the muffle.

In particular, a pull-out stop is provided as a limitation of the extension movement of the food support from the guide, so that by mistake too far undressing on the one hand can not fall out of the baking tray and on the other at Pulling out far too large angle of tilt can not result.

In the following, the invention will be described by way of example with reference to the drawings based on preferred embodiments. Show it:

1 a top view of a cooking appliance,

2 a view of a side wall of the Garraummuffel with an insert carrier,

3 the section BB through the insert carrier,

4 the section AA through the insert carrier and

5 a side view of the baking sheet.

1 shows a cooking appliance 1 in a frontal view and the view through the cooking appliance door. On both side walls 15 is an insert carrier 20 attached, which is a frame element 24 with guides 22 includes. The frame element consists of two roughly vertical, but slightly oblique, aligned wire hangers 24 , at which at regular intervals and roughly horizontally, but at a slight angle, aligned guides 22 are attached. The guides 22 include two spaced wire brackets 26 with a distance from each other that is sized so that the leading edge 42 of the baking tray 40 can be guided in it.

One insert carrier each 20 is on every sidewall 15 attached at a slight angle of inclination of 2 °, that of the muffle opening 11 to the device interior 12 is sloping. For the sake of clarity, was in 2 the angle α is shown oversized. The insert carrier of the muffle opening is thus a little bit higher than inside the device, ie z. B. adjacent to the fan.

To the maximum extraction of the baking tray 40 from the oven muffle 10 To limit, serves a range of longitudinal struts 26 as a stop edge 27 , 5 shows a baking tray 40 so that it can be inserted with its edge on the left into the muffle. The leading edges grip 42 in the guides 22 the insert carrier 20 , There are at a distance of 2/3 to 3/4 of the baking tray depth away from the front edge of the baking tray stops 44 as local depressions in the leading edges 42 imprinted. Once when pulling out the baking sheet 40 from the muffle these attacks 44 with the stop edges 27 contact, so the user feels a significant resistance to further withdrawal and recognizes that the outer end position of the baking sheet has been reached. In this position, the focus of the baking tray and the food thereon is clearly outside of the muffle. Both a game in the leadership of the baking sheet, as well as elastic deformation of the storage ensure that the baking tray is tilted forward. If the inclination or inclination is too great, there is a risk that the food will slide off the baking sheet. It was recognized that this risk is great when the skew angle in the outer end position is greater than 6 ° and this maximum angle is in the IEC 60335-2-6 required.

By installing the insert carrier 20 with the described inclination angle α of 2 °, the maximum skew angle in the outer end position is partially compensated. If, for example, an exactly horizontal extension direction of the food support would result in a tilt angle of 7 °, this is thus reduced to a permissible 5 °.

For fastening the insert carrier 20 on the side walls 15 Holes are provided on side walls, in which a made of plastic bushing insert 28 is plugged. Due to elastic deformation when inserting the socket insert 28 in the opening of the bore, a flange of the bushing insert, which is larger than the bore itself, inserted and so positively hold the female insert to the side wall. The frame elements 24 have a U-shaped basic shape and at the end of the flanks a circumferential groove, in which the socket insert 28 molded latches engage and so is the respective frame element 24 on the side wall 15 held.
