Description

Pull-out system and household cooker

The present invention relates to a pull-out system for a Haushaltsgargerät and a Haushaltsgargerät. For cooking appliances such as ovens, microwave ovens or ovens with microwave function, there are so-called pull-out systems, which allow the user to pull out accessories such as food support significantly further from the Haushaltsgargerät than would be possible with normal Einhängegittern. DE 10 2008 010 501 A1 describes a pull-out system for a cooking appliance with two rails which are movable relative to one another and which are displaceable relative to one another by means of rollers.

Against this background, an object of the present invention is to provide an improved extraction system.

Accordingly, a pull-out system for a Haushaltsgargerät is proposed with a support grid for receiving a plurality of superposed Gargutträger and a guide means by means of which the support grid is guided so that it is arranged between a retracted state in which the support grid in a cooking space of Haushaltsgargeräts, and an extended state, in which the support grid is arranged at least partially outside the cooking chamber, is displaceable, wherein the guide device has at least one running rail and at least one roller and wherein the at least one roller is adapted to, when moving the Auszugsssys- system of the retracted state unroll in the extended state or vice versa on the at least one running rail.

Due to the fact that the support grid, in which a plurality of superstructure carriers arranged one above the other can be received at the same time, can be moved out of the cooking space in its entirety, it is possible to dispense with a separate guide device for each individual food support or for each shelf level. The thermal mass of the extension system is only slightly higher than in known pullout systems, the However, only one food support can accommodate each. Furthermore, this makes it possible to realize a cost-effective pull-out system, since a separate pull-out system is not required on each rack level. With the help of the rollers, the support grid can be positioned at a distance from side walls of the cooking chamber. As a result, a sparkover is prevented. Preferably, the extension system is tuned with respect to its antenna effect so that it undergoes little or no self-heating in the microwave operation of Haushaltsgargeräts. The extension system is preferably removable from the oven. In particular, the extension system can be suspended in the oven. This allows the extraction system to be cleaned, for example, in a dishwasher. In addition, the extraction system is preferably also pyro lysefähig. The rollers can also be referred to as guide rollers. The rails can also be referred to as guide rails.

According to one embodiment, the at least one running rail can be fastened to a side wall of the cooking chamber of the household cooking appliance.

Preferably, the pull-out system has a running rail arrangement with two rails spaced apart from one another. The track assembly is tuned in terms of their antenna effect so that a self-heating in the microwave mode of Haushaltsgargeräts is prevented or reduced. The rails are connected by means of connecting struts and mounting struts. The mounting struts are adapted to attach the track assembly to the side wall of the cooking chamber. Preferably, an extension system is provided on each side wall. According to a further embodiment, the at least one roller is rotatably mounted on the support grid.

Preferably, a plurality of rollers are provided. In particular, each runner four castors are assigned.

According to a further embodiment, the at least one running rail is fastened to the supporting grid. The running rail can be screwed or welded to the support grid, for example.

According to a further embodiment, the at least one roller is rotatably attachable to a side wall of the cooking chamber of the Haushaltsgargeräts.

The pullout system may include roller carrier on which the rollers are rotatably mounted. At least one roller carrier can be provided on each side wall.

According to a further embodiment, the at least one roller is made of a plastic material or a ceramic material.

By using a non-metallic material for the roller electrical insulation between the support grid and the cooking chamber can be achieved. A sparkover is thereby prevented. The diameter of the rollers is preferably so large that sufficient to prevent a flashover gap width between the support grid and the cooking chamber is achieved.

According to a further embodiment, the at least one running rail has a circular or oval cross section and the at least one running roller has a concave running surface corresponding thereto.

The rails can be tubular or solid. By using tubular rails, the thermal mass of the extraction system can be reduced.

According to a further embodiment, the guide means on two spaced-apart rails.

The rails are arranged horizontally and parallel to each other and connected to each other by means of the vertically arranged connecting struts and fixing struts. The fastening struts are used to attach the pull-out system to side walls of the cooking chamber. In particular, the fastening struts can be suspended in the side walls. According to a further embodiment, each track is assigned four rollers, each track being arranged between two pairs of rollers.

This ensures a reliable and play-free guidance of the rails. Alternatively, each running rail or at least one of the rails can be assigned to three rollers.

According to a further embodiment, the rollers are rotatably mounted on a roller carrier.

Preferably, two roller carriers are provided, to each of which four rollers are attached. The roller carriers can be connected to the support grid. Alternatively, the roller carrier can be attached to side walls of the cooking chamber. Furthermore, a Haushaltsgargerät is proposed with such an extension system.

The Haushaltsgargerät may be an oven, a microwave oven, a steamer, a microwave oven or the like. Preferably, the household cooking appliance has a microwave function.

Fig. 1 shows a schematic perspective view of a Haushaltsgargeräts 1. The Haushaltsgargerät 1 is for example an oven, a microwave oven, a Dampfgargerät, a microwave oven or the like. The Haushaltsgargerät 1 has a muffle or a cooking chamber 2, which is closed by a door 3. The Haushaltsgargerät 1 can be pyrolyzed. That is, the cooking chamber 2 can be heated to temperatures of over 450 ° C for cleaning. The cooking chamber 2 may be arranged inside a housing of the Haushaltsgargeräts 1. The door 3 is shown in Fig. 1 in its closed position. By pivoting about a provided at a lower end of the door 3 pivot axis, the door 3 can be closed or opened. Alternatively, the door 3 can be struck laterally on the cooking chamber 2. Furthermore, the door 3 can be arranged on a withdrawable from the cooking chamber 2 baking carriage. At an upper portion of the door 3, a handle 4 may be provided. The cooking chamber 2 has a bottom 5, a cover 5 arranged opposite the bottom 5, a rear wall 7 arranged opposite the door 3 and two side walls 8, 9 arranged opposite one another. The cooking chamber 2 is preferably cuboid or cube-shaped. The cooking chamber 2 may be made of a metal material, in particular of a steel sheet.

Fig. 2 shows a schematic perspective view of an embodiment of an extension system 10 for the Haushaltsgargerät 1. Fig. 3 shows another schematic perspective view of the extension system 10. Fig. 4 shows a schematic perspective view of an embodiment of a support grid 1 1 for the Pull-out system 10 and FIG. 5 shows a schematic perspective view of an embodiment of a slide assembly 12 for the extension system 10. In the following, reference is made to FIGS. 2 to 5 at the same time. The extension system 10 can be arranged in the interior of the cooking chamber 2 of the Haushaltsgargeräts 1. The extension system 10 has the support grid 1 1, which is set up for recording, in particular for simultaneous recording, a plurality of food carriers to be arranged one above the other. The food supports can be, for example, gratings, grill pans, fat pans, baking trays or the like. The support grid 1 1 has vertically extending struts 13, 14 and horizontally extending struts 15, of which in FIGS. 2 to 4 only one is provided with a reference numeral.

The number of struts 15 is arbitrary. For example, the support grid 1 1 ten struts 15 have. The struts 15 are preferably arranged in strut pairs 16 to 20. Each strut pair 16 to 20 has two horizontally extending struts 15, wherein a respective food support between two struts 15 of the respective strut pairs 16 to 20 can be arranged. The respective upper strut 15 of a strut pair 16 to 20 serves as a tilt protection, so that when you take off the respective food support this can not tip. Alternatively, the upper strut 15 can be replaced by any other anti-tipper element. Each strut pair 16 to 20 forms an insertion level of the extension system 10. The support grid 1 1 is tuned with respect to its antenna effect that it experiences a low self-heating when used in a Haushaltsgargerät 1 with microwave function. The extension system 10 has, in addition to the support grid 1 1 on a guide device 21, by means of which the support grid 1 1 is guided so that it between a retracted state shown in Figs. 2 and 3, in which the support grid 1 1 in the cooking chamber. 2 Household cooking appliance 1 is arranged, and a not shown extended state in which the support grid 1 1 is at least partially disposed outside of the cooking chamber 2, is displaced. The guide device 21 includes the track assembly 12 with at least one horizontally disposed track rail 22, 23. The guide device 21 may, for example, two rails 22, 23 have. Alternatively, the guide device 21 only a running rail 22, 23 have.

The rails 22, 23 are preferably spaced apart from each other and with the aid of two vertically arranged connecting struts 24, 25 and two vertically arranged mounting struts 26, 27 connected to each other. The track assembly 12 is also tuned in terms of their antenna effect so that when used in a Haushaltsgargerät 1 with microwave function undergoes little self-heating. With the aid of the fastening struts 26, 27, the extension system 10 can be fastened to one of the side walls 8, 9 of the cooking chamber 2. In particular, such an extension system 10 is attached to each side wall 8, 9. The extension system 10 is preferably removable from the cooking chamber 2. As a result, the extension system 10 can be cleaned, for example, in a dishwasher. Furthermore, the extraction system 10 is also capable of pyrolysis and can be cleaned with the aid of a pyrolysis function of the household cooking appliance 1.

The guide device 21 has, in addition to the guide rails or rails 22, 23 at least one roller 28 to 31. The number of rollers 28 to 31 is arbitrary. The rollers 28 to 31 are rotatably attached to the support grid 1 1. In particular, the rollers 28 to 31 are rotatably mounted on a roller carrier 32, 33. Preferably, two roller carriers 32, 33 are provided. The roller carriers 32, 33 are preferably made of a steel sheet. The roller carriers 32, 33 are connected to the support grid 1 1, for example, welded. The roller carriers 32, 33 run parallel to the struts 15. For example, four rollers and 28 on the roller carrier 33 four rollers 28 to 31 may be provided on the roller carrier 32. Each track 22, 23 are preferably associated with four rollers 28 to 31, wherein each track 22, 23 between two pairs of rollers 28 to 31 is arranged. The rollers 28 to 31 are adapted to unroll when moving the extension system 10 from the retracted state to the extended state or vice versa on the at least one track rail 22, 23. The rails 22, 23 preferably have a circular or oval cross-section, wherein the rollers 28 to 31 have a concave running surface corresponding thereto. The rollers 28 to 31 are preferably made of a heat-resistant plastic material or a

Made of ceramic material. In this way, an electrical insulation of the support grid 1 1 can be achieved by the rail assembly 12.

By using the non-metallic rollers 28 to 31, a minimum distance between the support grid 1 1 and the side walls 8, 9 of the cooking chamber 2 can be achieved. As a result, a sparkover is prevented. Since the support grid 1 1 as a whole in the cooking chamber 2 retractable or extendable from this, can be dispensed with a separate known extraction system for each food support. The thermal

Mass of the described extension system 10 with multiple insertion levels is only slightly increased compared to a known extension system with only one insertion level. Due to the fact that a separate known pull-out system is not to be mounted on each rack level, a cost reduction can still be achieved. Characterized in that the extraction system 10 is tuned with respect to its antenna effect so that it experiences only a small self-heating, overheating of the extension system 10 can be prevented.

In a variant of the extension system 10, not shown in FIGS. 2 to 5, the rails 22, 23 or the rail arrangement 12 are fastened to the support grid 1 1. Furthermore, in this embodiment of the extension system 10, the rollers 28 to 31 and the roller carrier 32, 33 attached to the side walls 8, 9 of the cooking chamber 2 of the household appliance 1.
