Definitions

  • Viewing windows of the type concerned are common, they are usually arranged in the front doors of ovens or the like.
  • the following description is given for domestic ovens, although the invention can also be used for any other device which has a viewing window which separates a temperature-increased interior from the outside environment and through which it is possible to look into this room at an elevated temperature from the outside.
  • the disks enclosing the angle of inclination are preferably arranged in such a way that the inclination of the disks relative to one another extends in a vertical direction. Depending on the application, the disks can converge upwards as well as diverge upwards.
  • the temperature-reducing effect of the inclination is presumably due to certain radiation patterns, and possibly also through improved convection.
  • the non-vertical multiple reflection not only has the advantage that overall heat is dissipated laterally into the viewing window frame, but also the advantage that punctiform overheating of the Panes that can swing up due to vertical multiple reflection can be avoided, and thus a more uniform temperature distribution over the panes and in particular the outer pane can be achieved.
  • the temperature of the outer pane for parallel panes was 95 ° C, and for an arrangement with an inclined center pane, the temperature of the outer pane was 90 ° C.

Claims (12)

  1. Hublot pour un appareil à température interne élevée, notamment pour un four ménager ou un four de boulangerie, comportant un agencement d'au moins trois plaques mutuellement espacées de verre, de vitro-céramique ou d'un autre matériau transparent et résistant à la chaleur qui sont tenues par un cadre commun, caractérisé par le fait que le hublot (4) comporte une plaque intérieure (10), une plaque extérieure (6, 32) et au moins une plaque intermédiaire (8, 28) disposée entre deux et par le fait que la plaque intermédiaire (8, 28) forme un angle aigu avec la plaque intérieure et la plaque extérieure.
  2. Hublot selon la revendication 1, caractérisé par le fait que la plaque intermédiaire (8, 28) forme l'angle aigu avec la plaque intérieure et la plaque extérieure dans la direction verticale.
  3. Hublot selon la revendication 1 ou 2, caractérisé par le fait que l'angle aigu est compris entre 0,5 et 10°.
  4. Hublot selon la revendication 3, caractérisé par le fait que l'angle aigu est compris entre 2 et 6°.
  5. Hublot selon l'une des revendications 1 à 4, caractérisé par le fait que parmi les trois plaques, l'une détermine en tant que plaque de base (6, 32) le plan du hublot (4).
  6. Hublot selon la revendication 5, caractérisé par le fait que la plaque extérieure (6, 32) éloignée de la chambre intérieure (12) à température élevée constitue la plaque de base.
  7. Hublot selon la revendication 5, caractérisé par le fait que la plaque extérieure (6, 32) et la plaque intérieure (10) sont sensiblement parallèles entre elles.
  8. Hublot selon l'une des revendications 5 à 7, caractérisé par le fait que la plaque intermédiaire (28) converge vers le haut, vers la vitre de base (6).
  9. Hublot selon l'une des revendications 5 à 7, caractérisé par le fait que la plaque intermédiaire (28) diverge vers le haut de la vitre de base (6).
  10. Hublot selon la revendication 5 avec quatre plaques ou plus, caractérisé par le fait qu'il comporte deux plaques inclinées (40, 42) dont les directions d'inclinaison sont réciproquement opposées.
  11. Hublot selon l'une des revendications 2 à 7, dans lequel la plaque extérieure (32) éloignée de chambre (12) à température élevée et la plaque intérieure (28, 40) immédiatement voisine convergent vers le haut, caractérisé par le fait que le cadre commun (16, 34), au moins dans la région entre ces deux plaques (32, 28, 40), présente des ouvertures (36) sur sa face inférieure et sur sa face supérieure qui permettent une convection de l'air entre lesdites deux plaques (32, 28, 40) dans l'environnement à l'extérieur de la chambre (12) à température élevée.
  12. Hublot selon au moins une des revendications 1 à 11, caractérisé par le fait qu'au moins l'une des plaques est pourvue d'un revêtement (20, 22) qui réfléchit fortement le rayonnement thermique ou émet un rayonnement thermique réduit.
