Definitions

the invention relates to an oven muffle according to claim 1.
Ovens are already known in which a radiator arranged below the muffle and also a radiator arranged above the muffle are used for so-called catalytic self-cleaning of the muffle in addition to baking or otherwise preparing food in the muffle.
the interior of the muffle is brought to a high temperature ( ⁇ 550 ° C) in order to remove contaminated areas on the muffle inner walls.
ovens are known in which one or more heating elements are arranged inside the muffle, in particular just below and parallel to the muffle ceiling, so that manual cleaning of the muffle ceiling is not possible or is possible only to a limited extent. For this reason, such ovens have a catalytic shielding plate between the muffle ceiling and the radiator.
Catalytic self-cleaning has a number of disadvantages.
the catalytic self-cleaning requires a relatively high temperature. This temperature is to be chosen so that the desired cleaning effect can be achieved on the one hand, but that damage or a gradual destruction of the interior of the oven is also avoided on the other hand.
the catalytic self-cleaning requires a high energy input and is also associated with the further disadvantage that the oven cannot be used for a relatively long time otherwise during cleaning. This time is made up of the time in which the operating temperature is formed, the time of the actual cleaning and finally the time required to cool the oven down again to a temperature which allows the oven to be operated safely.
a microwave oven with a radiant heater unit which runs parallel to the heating chamber ceiling in the heating chamber of the microwave oven and with it End pieces is pivotally mounted in the rear wall of the heating chamber.
the pivot axis is arranged in the plane formed by the radiator unit.
the swivel unit consists of a swivel piece connected to the radiator end pieces and a bearing housing which surrounds the swivel piece and is formed from two bearing clamps.
the mechanical design of the swivel unit is thus relatively complex. It is also prone to wear. In addition, friction occurs during pivoting movements, which complicate the pivoting movements.
the invention has for its object to provide an oven muffle of the type mentioned, the pivoting mechanism is implemented in a simple manner constructively.
the radiator in the oven muffle according to the invention can be easily pivoted, the pivoting movement practically only depending on the gravity of the radiator; friction only occurs to a small extent during the swiveling movement. Another advantage is that the structurally simple structured swivel mechanism is not subject to any significant wear.
the oven muffle according to the invention can be realized using generally available oven heating elements which are provided with a flange.
the muffle 1 shown in Figure 1 is arranged in an electric oven. However, the arrangement according to the invention can generally be used in connection with ovens.
the muffle 1 is cuboid.
a radiator 2 in the area of the muffle ceiling serves to generate top heat and occupies two defined positions 2.1 and 2.2: in position 2.1 the radiator is arranged parallel and slightly away from the muffle ceiling, in position 2.2 the radiator is angled obliquely in the direction of the muffle floor. In this position the muffle ceiling is freely accessible.
the radiator 2 is essentially flat. It consists, for example, of multi-leg radiator elements with a flange 23 (FIG. 2). A bracket 3 arranged in the radiator level is used in particular for manual positioning of the radiator in positions 2.1 and 2.2.
the pivot axis of the radiator 2 is arranged outside the plane formed by the radiator 2.
the radiator 2 can be mounted in a fulcrum, which is implemented in the form of a cutting bearing.
the flange 23 of the radiator 2 has an edge which forms a cutting edge 24.
This cutting edge 24 is mounted in a pan 11 arranged on the rear wall of the oven muffle 1.
the pan 11 is formed in the embodiment shown in Figure 2 by a part 4.
the part 4 serves to guide the flange 23 and thus the radiator 2. It is arranged on the rear wall of the oven muffle 1 and is curved, for example, in the manner shown in FIG. It has a V-shaped cross-section, with one leg attached to the back of the oven muffle. The free ends of the two legs are bent inwards.
Part 4 consists e.g. made of bent sheet metal. In its lower region, part 4 forms, as already mentioned, pan 11, which receives cutting edge 24; In its upper region, part 4 forms a stop limitation 41 for flange 23.
the flange 23 thus engages in the curved part 4, so that the radiator 2 with the flange 23 in the part 4 assumes at least two defined positions (2.1, 2.2).
the flange 23 closes recesses 12 which are provided for the radiator 2 in the rear wall of the oven muffle 1.
the flange 23 closes recesses 42 which are provided for the radiator 2 in the curved part 4.
the radiator 2 is arranged in its first position 2.1 parallel to the muffle cover for the intended use (heating the food to be cooked). In this position, the radiator 2 is held on the muffle cover by a fastening element 7.1, 7.2.
the fastening element (7.1, 7.2) is in the embodiment shown in Figure 2 from a mounting bracket (7.1) and from a corresponding knurled screw (7.2). This allows the radiator to be easily swiveled down and fastened to the muffle ceiling without tools.
the fastening element (7.1, 7.2) is arranged in particular in the vicinity of the loading opening (front side) of the oven muffle 1, that is to say on the side opposite the pivot axis, approximately centrally in the front of the oven muffle.
the knurled screw 7.2 is attached to a support of the radiator 2.
Two leading spacers 8, 9 pointing in the direction of the muffle cover are also fastened to this carrier. They are arranged on each side of the radiator, ie on the left and right with respect to the loading opening (FIG. 1) of the oven muffle.
the knurled screw 7.2 connected to the fastening tab 7.1 and the spacers 8 and 9 ensure that the radiator is held securely parallel to the muffle ceiling (position 2.1), which also ensures a constant coupling of the oven controller.
a catalytic intermediate plate can be retrofitted and attached between the radiator in its position 2.1 and the muffle ceiling.
the heater 2 is thus pivotally mounted in a guide part 4 in the rear area of the oven muffle 1 on its rear wall between positions 2.1 and 2.2.
the pivot axis of the radiator is arranged outside and in particular below the plane formed by the radiator 2.
a guide bracket 5 which is positioned on the outside of the oven muffle 1 in the positioning of the heating element shown in FIG. 2, serves as a shield and for guiding electrical cables.
6 designates a thermostat sensor tube which is provided in the plane of the radiator or parallel to it.
