Definitions

  • the present invention relates to a cooking appliance, in particular a high-installation cooking appliance, with at least one muffle defining a cooking space muffle opening, a door for closing the muffle opening and controlled by a control device drive means for moving the door, wherein the drive means comprises at least one drive motor through which ropes connected to the door can be moved.
  • the present invention further relates to an associated method of operation.
  • Ropes are connected to one side of the bottom door and are deflected by the drive motor to the bottom door via pulleys.
  • the pulleys are equipped with switching lugs and associated switches to detect a pinching. This can be done for example by time-delayed switching on the two pulleys.
  • a generic high-installation cooking appliance is also known for example from DE 101 64 237 and DE 102 28 141.

  • the pitch cables are shifted linearly in the opposite direction, accordingly the door is linearly displaced.
  • pitch cables are connected to the door in the general case means that they are attached to the door directly or to an element connected to the door, e.g. B a telescopic rod, can be attached.
  • the drive motor is mounted centrally on a surface of a housing body and the pitch cables are deflected by the engine in vertical, hollow telescopic rods.

Then, it is particularly advantageous if at least one guide tube for a load-bearing section of a pitch cable (on which acts a tensile force exerted by the door) extends from a guide housing connected to the drive motor up to and including an associated support. As a result, the pitch cable is protected in this area from external influences and does not slide directly on the support so that it does not have to be particularly resistant to abrasion.

Due to the elastic deformability of the guide tube, this is deformed (bent) by the load applied to a load-bearing section of a pitch cable in such a way that it presses on the support in a load-dependent manner. As a result, a load measurement variable can be measured on the support. In addition, the elastic energy in the guide tubes in the stalling Einklemmfall the then relieved ropes slightly spring back, whereby a circuit of a corresponding switch is supported.

  • Signals of the switching devices detects a pinching.
  • the invention can be used particularly advantageously in a high-installation cooking appliance with a bottom-side muffle opening and a bottom door.
  • the invention is also achieved by a generic cooking appliance in which at least one load-bearing section of a cable is deflected between the drive motor and the door on a support and runs at least between the drive motor and the support in a guide tube.
  • the at least one guide tube is deflectable under load, in particular elastically deformable, and / or at least this edition with a switching device is equipped for load measurement.

  • FIG. 10 shows the embodiment of the cooking appliance according to FIG. 9 in a front view in a sectional view on the sectional plane IV-IV from FIG. 9, with some elements no longer being shown for a clearer representation.
  • the lower runners 60 are therefore shown only in part.
  • the pitch cable 58 and the guide tubes 56 are deflected on the support 57 from the horizontal to the vertical.
  • a (deflecting) force is thus released by the respective load-bearing portion of the pitch cables 58 via the elastically deformable guide tubes 56 which is substantially dependent on the load on the load-bearing portion of the pitch cable 58, including the weight of the bottom door 7 and their load.
  • an overloading of the floor door 7 or a trapping case By measuring the deflecting force, in particular the respective normal force on the corresponding support 57, it is possible to detect, for example, an overloading of the floor door 7 or a trapping case.
  • An overload of the bottom door 7 is measurable, for example, by exceeding a certain threshold load.
  • An entrapment case in the closing direction of movement of the bottom turret 7, ie mostly between bottom door 7 and housing 1, and in the opening direction of the bottom door 7, that is usually between floor door 7 and worktop can be detected, for example, if a difference between FnI and Fn2 becomes greater as a certain set threshold. Alternatively, time differences in the discharge between both sides can be detected.

  • further evaluation options can be used to detect the trapping case, such as a speed change of the load which possibly exceeds a certain threshold value or deviates from a setpoint value (eg a traversing speed or speed ramp) and thereby indicates trapping.
  • FIG. 12 shows the fastening elements 59 from FIGS. 9 and 10 as an oblique view on the front or rear side in greater detail. It is shown that the fastening elements 59 attached to a pitch cable 58 at the end have a slot 68. This slot is for the described high-mounted cooking appliance of particular advantage, because a connection of Garellakorpus or attached thereto drive and bottom door can be particularly easily and accurately achieved, especially when using a pitch cable. Because then the drive unit including motor, gearbox, guide housing, guide tubes and pitch cables can be pre-assembled, especially with the installation of the pitch cable.
  • the position of the pitch cable in the guide tubes then does not need to be set exactly, because after attachment of the drive unit to the device a fit of the pitch cable, and thus the bottom door with respect to the body, can be done through the slots 68.
  • a screw guided through the respective elongated hole 68 need to be tightened.
  • an insertion tolerance of the pitch cables approximately corresponding to the length of the oblong hole 68 can be set in their guide tubes or relative to the pinion. be the same. This results in a simplified assembly of the cooking appliance and also a possible readjustment of the position of the bottom door in relation to the body or the muffle.
  • Fig. 13 shows in an oblique view from the front above the yoke 64 of Fig. 10.
  • the yoke has centrally a passage 69 for connecting the motor or the transmission with the guide housing and thus the pitch cables.
  • Each side of a recess 70 for the implementation of fasteners for fixing the yoke 64 on the cooking appliance is present.
  • FIG. 14 shows a front view of the yoke 64 with motor 9, transmission 65 and guide housing 54 attached thereto.
  • the guide tubes 56 extend laterally from the guide housing and are deflected downwards in a lateral area.
  • the yoke is supported and fixed on the housing body 34 (shown here only with a support portion). As a result, the guide tubes 56 are articulated firmly on the guide housing. This results in the shown compact arrangement with high stability.
