Definitions

  • the invention relates to the structural configuration (details design) of the griller or sandwich maker grilling plate with removable plates, so that the losses are reduced and the appliance performance is improved, while at the same time reducing its non- uniformities resulting from the configuration of the heating element.
  • the heating element is typically located at a distance from the appliance grilling plate, and the energy is transferred to it by radiation.
  • These components are generally called reflectors.
  • the heat transfer from the heating elements through radiation is directed partly to the appliance grilling plate and partly (quite important) to the environment (the appliance’s sides or interior).
  • the reflectors in which the heating elements are assembled, are made of reflective materials and are suitably configured, so that the radiant heat returns as far as possible to the grilling plate.
  • ribs are sometimes placed on the appliance plate (on the path of heating element) to increase the heat absorption and lessen the losses inside the appliance.
  • these ribs by locally concentrating high temperature, create non- uniformities in the grilling plate temperature and, hence, there is no homogeneous grilling.
  • part of the heat is locally re-radiated towards the outside environment.
  • the present invention on the one hand, there is an increase in heat absorption and a reduction of losses on the outside of the appliance by using a collecting ribs (8) array on the outside of the heating element contour without causing excessive temperature increases in the grilling plate.
  • a collecting ribs (8) array on the outside of the heating element contour without causing excessive temperature increases in the grilling plate.
  • the external ribs array consists of two or more ribs of different height, so that each collects part of the heating element radiation. Therefore, the heat is not released to the environment and no overheating occurs.
  • the assembly of the collecting ribs array (8) is dimensioned such that the first is shorter than the next (s) to collect only part of the radiant heat (the horizontally directed radiation), and the next(s) is (are) longer to collect the remaining escaped radiation.
  • the internal temperature balancing ribs (9) collect locally radiant heat only at points, where lower temperatures are observed, in order to homogenise the plate
  • Figure 1 shows a longitudinal sectional view of the constructional details of a griller, as well as the constructional design of the plate with the collecting ribs (8) and balancing ribs (9), so that the appliance efficiency is improved while saving energy.
  • the appliance heating element (2) On the reflector (1) surface the appliance heating element (2) is located.
  • the assembly of these two components is mounted onto the appliance upper (3) or lower (4) bodies (griller).
  • the grilling plates (5) are placed by the user over the assembly of these two components using the supports (6), (7) at the front and back respectively of the appliance upper or lower body. This support allows the user to easily remove or place them, so that it is easy to clean them after use.
  • the same figure shows the details of the plate with the arrays of the peripheral temperature collecting ribs (8), as well as of the temperature balancing ribs (9), which improve the uniformity of the low temperature regions.
  • Figure 2 shows the components involved in this structure in a cross-sectional way.
  • Figure 3 shows a plate form with collecting (8) and balancing ribs (9), which, as discussed above, lessen the appliance losses and improve its performance.
  • Figure 4 shows a detail of Figure 1, so that the structure of the collecting ribs array (8) is distinct.
  • Figure 5 shows a detail of Figure 2, so that the structure of the collecting ribs (8) and balancing ribs array (9) is distinct.

Abstract

L'invention concerne un ensemble d'au moins deux nervures perpendiculaires au côté arrière de la plaque, et des nervures de collecte (8) à l'extérieur du contour d'élément chauffant pour collecter le chauffage s'échappant des côtés soit directement irradié, soit réfléchi dans le réflecteur d'appareil. Les nervures d'équilibrage (9) sont situées à l'intérieur du contour d'élément chauffant dans des régions à basse température et absorbent le rayonnement diffus des éléments chauffants, ce qui élève leur température.
