Definitions

  • the innovation relates to an oven which is aligned with a high-frequency heating device and / or a thermal heating device, a vapor opening being provided on an upper muffle wall.
  • Thermal heating devices which are designed as hot air or circulating air heating, consist of a radiator and an associated blower.
  • a circulating air blower is arranged behind an air baffle in the interior of the oven, which has a central suction opening and blow-out openings for circulating the hot air inside the oven.
  • the air circulation fan is surrounded by an air heater.
  • the temperature sensor of a temperature controller that controls the radiators is located in the baking chamber. If this proposed arrangement is to be carried out in a microwave-proof manner, then the effort for the passage point of the forced-air fan in the oven rear wall means to drive.
  • a hot air heater has become known from EP-O 245 617, which has symmetrical suction and blow-out hole patterns in the central rear fan position in the oven rear wall.
  • the hot air heating chamber extends over the entire back wall of the oven.
  • the task of the innovation is therefore to create a thermal heating device, whereby a good temperature uniformity is achieved and the oven is microwave-tight.
  • the arrangement according to the invention for solving this problem is characterized in that the hot-air heating system consisting of a radiator and a fan is arranged in a hot-air housing which is located outside the oven muffle on the rear wall of the oven and encloses the fan and the heating system, and in that is provided by the hot-air housing certain area of the oven back wall has asymmetrically arranged hole group patterns for top heat, bottom heat and the suction hole group for the fan.
  • the thermal heating device which is designed as a hot air heater, consists of a radiator 1, a hole group for top heat 2 and a hole group for bottom heat 3, a fan 4, a fan drive 5 belonging to fan 4 and a fan wheel belonging to fan 4, a hot air housing 7 and an oven rear wall 8.
  • the radiator 1 which extends over one half of the oven rear wall 8, is arranged behind the hole group for top heat 2 and the hole group for bottom heat 3.
  • the fan 4 which draws in preheated cooking space air via air intake openings, is in the half next to the radiator 1 Oven rear wall 8, at the level of the hole group for top heat 2, attached.
  • This arrangement of heating element 1 and fan 4 according to FIG. 1 is also conceivable as a mirror image of the selected embodiment.
  • the hot air housing 7 enclosing the heater 1 and the fan 4 advantageously enables the air radially blown off by the fan 4 to be led to the heater 1 with a uniform intensity, in that the oven rear wall 8 has a hole group pattern for the intake air of the hot air blower, the If the fan 4 is arranged off-center in the upper half of the oven rear wall 8, the top heat and bottom heat can enter the cooking chamber in a directed manner. Since the central region of the oven rear wall 8 has no hot air outlet, a temperature equalization in the cooking chamber is achieved with a reduced circulation effect of the feeds Hot air. A direct supply of hot air to larger areas of the food is avoided if the food is placed in the center of the cooking space. As a result of the design of the hole group pattern for top heat 2, bottom heat 3 and the intake air of fan 4, the cooking space is microwave-tight.
  • the microwave tightness of the cooking space is achieved more easily than the fact that no structural arrangements have to be guided through the oven rear wall 8 than is possible with fan-operated axles in the cooking space.
  • the hot air housing arranged behind the hole group patterns supports the microwave tightness of the overall arrangement
  • the fan arrangement and the arrangement of the hot air housing 7 can be seen in section B-A.
  • the arrangement of the fan depends on the design of the fan drive 5. With the principle of the hot-air housing design according to FIG. 1, a good yield of the hot-air heating can be achieved analogously for each fan arrangement.
