Definitions

  • the invention relates to a gas cooker, in particular for caravans, with at least one radiation burner covered by a heat transfer plate and formed from a perforated burner plate according to the preamble of claim 1.
  • Such a gas cooker is known from DE-GM 80 26 018. With this gas cooker, the exhaust gas generated during combustion is discharged via a discharge duct on the back of the gas cooker. Due to the special design of this discharge channel, it is possible to use the gas cooker to heat a room. This ge schieht in that sucked air on the A • crystallineka-. nal is passed by.

  • the gas furnace as a heater would have to be ensured in any case that no heat damage could occur in the vicinity of the discharge duct. To do this, it would at least be necessary to provide the discharge duct with elaborate shielding or insulation, as a result of which additional space is used which is lost for other use.
  • the object of the invention is to improve a gas cooker of the type described in the introduction in such a way that, with optimal combustion of the gas supplied, shielding or isolation of the discharge duct can be dispensed with without having to fear heat damage in the immediate vicinity of the discharge duct.

  • one embodiment of the invention provides that the central axis of the pressure compensation opening runs at an acute angle, inclined to the direction of flow.
  • the continued cooking zone which extends beyond the projection of the burner plate, can be heated with the exhaust gas flowing through it, due to the exhaust gas collecting space arranged underneath, thereby making good use of the heat expended for the operation of the gas cooker ⁇ menergy results.
  • the exhaust gas collection space enables the lateral connection of the discharge duct according to the invention, so that the rear of the cooker, free of channels, enables the cooker to be arranged in a sealed manner, for example on the inside of a wall of a caravan.
  • the parallel arrangement of the discharge duct and the feed duct leads to a space-saving duct arrangement, which is particularly important in the case of narrowly limited space conditions.
  • This configuration results in a particularly compact arrangement of the channels, which can thereby be provided in a simple manner with a common cladding which can be optically integrated with a wall in question.
  • a plurality of burner plates each with a further cooking zone sufficient beyond their projection, is assigned a common flue gas collecting space. Due to the inventive multiple flue gas collecting chamber, there is the possibility of having a large continued cooking zone available even when only one burner plate is in operation.
  • one embodiment of the invention provides that the heat transfer plate is integrated in a receiving and storage plate forming part of a sink, this embodiment having a very advantageous effect because of the small space requirement for caravans.

Abstract

Un ensemble de plaques de cuisson à gaz destiné en particulier aux caravanes, possédant au moins un brûleur du type à jets sous la forme d'une plaque de brûleur (1) perforée recouverte d'une plaque de transmission de la chaleur (2), qui peut être alimentée en gaz (6) et en air de combustion (12) par une conduite d'alimentation. Pour réduire les températures du gaz d'échappement de l'ensemble de cuisson à gaz, une partie de l'alimentation en air forcé est séparée de celle qui est utilisée comme air de combustion et est mélangée au gaz d'échappement produit au cours de la combustion à mesure qu'il avance vers un tuyau d'évacuation (27). Le premier mélange d'une partie de l'air d'entrée s'effectue par des ouvertures (18) situées dans une plaque d'isolation (7) qui reçoit des plaques de brûleur (1) et un espace (9) situé sous les plaques de brûleur (1), dans lequel une partie de l'air d'entrée est mélangée avec le gaz d'échappement; le mélange arrive dans une chambre de collecte (19) qui est rincée par une nouvelle alimentation d'air d'entrée venant d'un espace (20). Après avoir quitté la chambre de collecte (19), le gaz d'échappement traverse une ouverture de sortie (23) pour aller dans un collecteur (26) du tuyau d'évacuation (27). Lorsque le gaz d'échappement quitte la chambre (19) de collecte du gaz d'échappement et entre dans le collecteur (26), une nouvelle alimentation d'air d'entrée traverse les ouvertures (28 et 29) et se mélange au gaz d'échappement, et la température du gaz d'échappement s'en trouve réduite à un niveau tel qu'aucun endommagement dû à la chaleur ne peut être causé au voisinage du tuyau d'évacuation (27).
