Definitions

  • the invention relates to an oven with a closable by an oven door cooking chamber and arranged at the rear of the cooking chamber fan, in which a hot air blower is passed from the hot air flows through Heilleitmaschine and through air outlet openings in the fan chamber in the cooking chamber to the food.
  • the present invention is therefore an object of the invention to improve a baking oven of the type mentioned in view of the aforementioned findings so that a direct onflow of the lateral cooking chamber walls, but also a direct onflow of the food is largely prevented.
  • each air outlet opening is provided with an air guide element, which with respect to the Respective flow direction of the outgoing from the hot air blower hot air flows obliquely inclined, one of the air outlet opening outgoing in the wiring air-causing lamellae is provided.
  • the advantages obtained by the invention are optimally achieved in particular when a plurality of the air outlet opening radially moving lamellae are provided. As a result, hot air streams flowing in all possible directions within the blower chamber are captured by the swirl-forming, radial lamellae and combined in a wired hot air stream directed in a targeted manner into the cooking chamber.
  • each air guide element is arranged within the fan chamber, although an external arrangement of the air guide element or an arrangement within the air outlet openings is conceivable.
  • the lamellae extend radially away from the opening edge of the preferably circular air outlet opening. In this way, although an effective wiring of the incoming hot air flows is achieved, however, an impairment or reduction of the opening cross section of the air outlet opening is avoided. In order to obtain an optimal twisting and bundling of the outgoing hot air flow from each air outlet opening, it is advantageous if the slanted slats are still curved in itself.
  • each air guide element is designed in the form of a hollow cylinder with peripherally projecting lamellae on the circumference of the cylinder and with free flow openings formed between these lamellae.
  • Figure 1 is a front view of the oven muffle of a baking oven in a schematic representation without oven door
  • FIG. 1 The top view of the oven shown cut open with
  • Figure 3 The enlarged view of a single air guide element.
  • the oven muffle (1) shown in Figure 1 is configured cuboid and shown without oven door.
  • the cooking chamber (2) has bottom and top side cooking chamber walls and side cooking chamber walls (3 and 4) and a rear cooking chamber wall (5).
  • slide rails (6) are attached to the side cooking space walls (3, 4) for holding retractable Gargutarrin (7), eg different design.
  • this is arranged overlapping a blower chamber wall (8) explained in more detail below.
  • This blower chamber wall (8) forms between the rear muffle wall (5) and the blower chamber wall (8) arranged in front of a blower chamber (9) ( Figure 2) within which blower chamber (9) is an electrically driven hot air blower (10) which is circular is surrounded by an electric heater (1 1) (FIG 2). Immediately in the amount of the hot air blower (10) is located in the blower chamber wall (8) has a suction port (12) through which the blower chamber (9) with the cooking chamber (2) communicates with air technology.
  • circular air outlet openings (13) are provided on the two lateral edges of the blower chamber wall (8), whereby in practice a plurality of such air outlet openings (13) can be arranged at said edges, but also at other locations of the blower chamber wall , Air-conducting elements (14) are connected directly in fluid communication with these air outlet openings (13), as shown in FIGS. 2 and 3 with reference to a section of the blower chamber wall (8) (FIG. 3).
  • Each air guide element (14) is designed as a structural unit in the form of a hollow cylinder and has at the periphery of the cylinder a plurality of peripherally extending from the opening edge of the outlet openings (13) extending lamellae (15), which move the air outlet openings (13) fully and substantially radially, as Figure 3 shows.
  • the air guide elements (14) are located inside the blower chamber (9).
  • The, for example, rectangular lamellae (15) are obliquely inclined relative to the respective radial (16) by an angle (a) and can be curved in itself, as indicated by an example with a dashed line (17). Between these slats (15) free flow openings (18) are formed.
  • the hot air blower (10) generates turbulent or wired hot air flows (19) in the blower chamber (9), which are supplied to the air outlet openings (13) in different flow directions or virtual flow axes.
  • these hot air streams (19) by the obliquely inclined and optionally spoon-shaped against the air outlet openings (13) cambered lamellae (15) bundled into a wiring in the cooking chamber (2) and in the direction of a oven door (20) directed hot air flow, as indicated in Figure 1 and 2 on both sides of the fan chamber wall (8).
  • These hot air streams (21) are reflected on the oven door (20) and flow through the central largely undirected Area (22) of the cooking chamber where their heat energy is transmitted evenly to the food and from where the amount of air through the air intake (12) through the hot air blower (10) is centrally sucked and fed to another circulation.

Abstract

La présente invention concerne un four comprenant une chambre de cuisson (2) qui peut être refermée par une porte (20), et possédant un compartiment de ventilateur (9) arrière dans lequel se trouve un ventilateur à air chaud (10) depuis lequel des courants d'air chaud sont dirigés à travers des éléments de guidage d'air (14) et des ouverture de sortie d'air (13) à l'intérieur de la paroi (8) du compartiment de ventilateur, pour atteindre la matière à cuire située à l'intérieur de la chambre de cuisson (2). Selon l'invention, les éléments de guidage d'air (14) qui portent des lamelles, permettent la production de courants d'air chaud qui se propagent en tourbillonnant à distance des parois latérale (3, 4) et de la zone centrale (22) de la chambre de cuisson (2).
