Abstract

The oven has a cooking chamber, which can be closed by a door and is equipped with upper and lower heating elements for top and bottom heating, the heating element for bottom heating being integrated into a dividing plate which can alter the volume of the cooking chamber. The dividing plate (5) is shielded from the floor (7) of the cooking chamber by heat insulation (8). Breaks (14) are provided in the side walls (9, 9') of the cooking chamber, and optionally in the rear wall, at the level of the guides (10) for the dividing plate (5). (Fig. 1) <IMAGE>

Description

! 84872 Electric baking and frying oven

The invention relates to a baking and baking oven according to the preamble of claim 1.

DE-OS 32 46 445 discloses a Lei oven and a frying oven according to this publication. The consumption of heating energy in this known baking and frying oven is reduced by means of a plug-in inlet part which divides the volume of the oven space and is formed as an injection. But it has been found that the inlet section radiates or dissipates a great deal of heat, and in addition the walls of the furnace space are heated to approximately the same temperature as the furnace space above 15a due to the heat conduction of the furnace space below the inlet part. Since now, when dividing the oven space on the basis of the bottom and roof side heating, only the upper oven space area is used per se or the product to be baked or baked is introduced, the heated lower area 20 is forced to be unused and the radiated or condensed heat is wasted.

The invention is therefore based on the object of obtaining assistance in this and ensuring that the part of the furnace space which is not used in connection with the reduction of the furnace space is not unnecessarily heated.

The solution of the present invention according to the invention can be seen from the characterizing part of claim 1.

Other preferred embodiments of the subject matter of the invention are set out in the subclaims.

The advantages obtained by the invention can be seen in the fact that in connection with the reduction of the furnace space, considerable savings in heating energy are also achieved, since the conduction of heat to the unused part of the furnace space is largely omitted.

An embodiment of the invention is described in silicon 2,84872 and will be described in more detail as follows.

In the drawing, Fig. 1 is a perspective view of an electric Lei-5 vinegar and parsnip chamber when the oven has a heated insertion part, Fig. 2 a front view of a baking and baking oven chamber when the oven is equipped with a device for automatically adjusting the height of the feed or oven space divider.

The baking oven chamber 1 for an electric baking and frying oven described in the drawing delimits an oven space 2 which can be closed by a door (not shown). The lei kiln chamber 1 has an electric heater 4 for underheating in the upper kiln space area (chamber roof).

The heater 4 for underheating is preferably integral with the plate-shaped furnace space inlet part 5 provided with an electrical plug contact 6 for the heater 4. With this inlet part 5, it is now possible to divide the oven space 2 so that a smaller oven space is also available for smaller baking and baking quantities, which can be heated in an energy-saving manner. In addition, only this part of the furnace space separated from the actual furnace space 2 is then also contaminated, while the rest of the furnace space part remains clean. The heater 4, which is integral with the furnace space 25 supply unit 5, is separated from the furnace space base 7 by a high temperature resistant thermal insulator 8, so that the heat transfer by radiating upwards from the heater 4 is forced upwards towards the chamber roof. Guide rails 10, 10 'for the insertion part are attached to the side walls 9 in the lower and central areas inside the oven chamber 30. The rear wall 11 of the oven space is provided with a corresponding height position for electrical sockets 12, 12 'for electrical socket contacts 6 in the insertion part 5, which are in communication with the control and switching elements of the baking oven and 3 84872 oven.

In order to now largely eliminate the conduction of heat from this furnace compartment 5 to the unused furnace compartment part below the insertion part 5 when the upper furnace compartment part 5 is inserted into the upper rails 10. holes 14. The holes 14 are then formed as a slit strip fitting running in a horizontal plane 10. The lateral holes 14 are preferably covered or covered with guide rails 11a for the inlet part 5, so that they cannot be seen in practice from the front by the user of the oven space 2. It is expedient to attach the guide rails 15 to the side wall 9 of the furnace space only in a point-by-point manner in order to reduce heat conduction or heat transfer from this side as well. Thermal insulation is placed around the outer wall of the baking oven chamber 1 in the usual manner, as a result of which the holes 14 in the chamber walls are covered outwards. It is also advantageous to provide the front frame 15 of the baking oven chamber 1 with similarly slotted holes 16, so that the conduction of heat from the upper oven compartment part to the lower oven compartment part is further removed.

According to a further embodiment of the invention, Fig. 2 25 shows an application example in which the heated furnace space inlet or furnace space divider part 5 'is not moved manually but automatically by means of a height adjustment device to the furnace space dividing position. The height adjustment device is then operated electrically and is actuated via a corresponding member. Said device consists of a DC motor 21 which can rotate clockwise and counterclockwise. This motor raises or lowers the furnace space dividing part 5 by means of a rope pull 22, guide strips 23, 23 'and a support angle 24, 24' for the furnace-35 splitting part 5 ', which are guided by guide and sliding rollers 25 in guide strips 23, 23 '. The side guide rails 10 '', here act as height limiting responses for the furnace space dividing section 5 '.
