Definitions

  • the invention relates to a pull-out device, in particular a telescopic pull-out device for at least one Food carriers in a cooking space of a cooking oven.
  • the invention is therefore based on the object easy-care pull-out device, in particular a telescopic pull-out device, for a food carrier of a cooking oven to accomplish.
  • the pull-out device is for at least one food support provided and designed in a cooking space of a cooking oven and includes rails (elongated support members) which or on which at least one food support can be placed or can be fastened, and guides (guide elements), in which the rails in plain bearings with sliding along Sliding surfaces are guided, the rails at least partially in their guides from the cooking space are extractable. Include at least on their sliding surfaces the rails, the guides or both the rails as well as the guides each one at the operating temperatures the oven's temperature-resistant sliding material (Material with good sliding properties, sliding material), so that a low sliding friction, i.e. a low coefficient of sliding friction, between the sliding ones Sliding surfaces of rails and corresponding guides is reached.
  • rails elongated support members
  • guides guide elements
  • the coefficient of sliding friction between two bodies is determined the frictional force that counteracts the movement when the surfaces of both bodies slide together or friction, and therefore referred to as sliding friction becomes.
  • the sliding friction force is proportional to Normal force that presses the two bodies together with the coefficient of sliding friction as a proportionality factor.
  • the sliding friction coefficient depends on the type and the Surface condition of the materials of the two bodies, so here the rail and the leadership.
  • the coefficient of sliding friction can be easily determined experimentally as the tangent of the angle of an inclined plane at which the one body on top of the other is uniform (with constant Speed) because then by the Movement force exerted by gravity just the friction force compensated.
  • the pull-out device for food carriers is based on the Invention on a, preferably linear, plain bearing and is therefore due to their no cage ball bearings or rollers easy to manufacture and to manage waiting.
  • the special sliding material has the advantage that the pull-out device even while the oven is in operation is smooth and has a comparatively long service life having.
  • the rails and / or the guides essentially entirely formed from the sliding material, for example as a coherent (one-piece) molded body.
  • the rails and / or the guides do not have to be completely consist of a sliding material. Especially at high Costs or a non-self-supporting property of the Sliding material, it can be more advantageous only to the Sliding surfaces of the rails and / or the guides the sliding material provide, preferably by applying a Layer (coating) of the sliding material.
  • prefabricated, massive moldings can also be made from the sliding material used on a generally base body not made of the sliding material the rails and / or the guides arranged stationary and their surfaces are at least partially the Form sliding surfaces of the slide bearings of the pull-out system.
  • This Variant has the advantage that the special shape for the plain bearing can be done through the sliding body, while standard shapes for the rails and / or guides can be used.
  • the pull-out device can be used for several items Cooking chamber levels are further developed by in appropriate Levels for one food support each two Rails and associated guides are provided.
  • the sliding surfaces of the rails and / or the guides can in one embodiment over the entire extension direction running management area, i.e. the area in which the rails and the associated guides sliding against each other are displaceable, or in a second embodiment only over part of the management area run (otherwise then unsupported).
  • the guides preferably limit movement of the associated ones Rails on at least one side so that the Rails with as little tolerance as possible linear in the guides are movable and do not slide out inwards or outwards can (lateral fixation of the rails in the Guides).
  • the sliding material can support the sliding effect be self-lubricating.
  • the sliding material and any other materials of the pull-out device even still temperature resistant at temperatures of at least about 500 ° C. Allow these special material properties it that the pull-out device even during a pyrolytic self-cleaning of the oven in Pyrolysis temperatures prevailing in the cooking compartment remain in the cooking compartment can and even through the pyrolysis of the cooking residues is cleaned.
  • the Sliding material not only thermally, but also opposite a soapy water, especially one in a dishwasher Usually used detergent, chemically resistant. This enables the pull-out device to be cleaned of greasy residues that build up during cooking and other organic residues by washing in soapy water, especially in a dishwasher.
  • the coefficient of sliding friction between the against each other sliding surfaces (sliding surfaces) of rails and associated Guides is generally set below 0.5, can in particular be below 0.4 and preferably even below 0.2.
  • the static friction between two bodies is the frictional force that counteracts the movement force when the two bodies are pressed together under a normal force and relative are at peace with each other.
  • the static friction is proportional to normal force with the coefficient of static friction as a proportionality factor. Stiction is practical always greater than the sliding friction. A particularly small one In most cases, static friction is caused by material combinations already achieved, if the sliding friction is chosen small.
  • the coefficient of static friction can be easily determined experimentally as the tangent of the angle of an inclined plane at which the one body is just beginning to slide on the other, because then the movement force exerted by gravity is just equal to the frictional force.
  • the pull-out device is in a cooking oven with a cooking space preferably detachable on the wall of the cooking space or permanently attached. With a detachable attachment is the Pull-out device removable from the cooking space, for example for cleaning or before pyrolysis, if the materials are not heat-resistant at the pyrolysis temperatures are.
  • the pull-out device includes for each a food support 5, 5 'two on opposite Side walls 3 arranged in a horizontal cooking space level elongated (linear) guides 4 for associated Rails 6.
  • each of the rails 6 is slidably mounted and axially (linear) essentially parallel to the associated cooking space level and slidable to the associated side wall 3.
  • the associated food support 5.5 'is free can be placed on the front end of the rails 6 arranged stops 41 and possibly by additional Limits such as pens and corresponding ones Holes fixed relative to the rails 6.
  • the food support 5.5 ' also permanently connected to the associated rails 6 his. With these measures, each food support 5.5 'is individual from the cooking space 1 by one through the pull-out path the rails 6 dependent path relative to the guides 4 extractable.
  • both food carriers are shown 5 and 5 'each with the oven door 20 open Pulled a little way out of the cooking space 1.
  • the guides 4 are on two perpendicular support rails 40 attached, which in turn on the associated side wall 3 are attached.
  • the carrier rails are preferably 40 releasably attached to the side walls 3, for example hooked into this and / or with a light releasable screw connection attached and thereby together with the guides 4 and the rails 6 located therein Removable from the cooking space 1, especially for cleaning or customer service purposes.
  • the carrier rails shown 40 can also be known lattice-shaped Carrier elements can be provided, which can also be inserted directly of food carriers in at least one level without Allow telescopic extension.
