Description

The present invention relates to a cooking appliance with at least one heatable cooking chamber and at least one cooking chamber door for closing a feed opening of the cooking chamber and with at least one ventilation opening for ventilating the cooking chamber. At least one closure element is provided for automatically closing and / or opening the ventilation opening.

For an economical and energy-efficient operation of a cooking appliance and to achieve optimum cooking results, it is advantageous to flush the oven with different amounts of air. In addition, a regulation of the air flow rate is very advantageous if a catalyst device for reducing fatty and odorous substances of the exhaust air or Wrasens is provided.

The known in the art ventilation flaps usually either do not allow different Garraumdurchspülungen or are structurally designed very expensive and are therefore more expensive and usually prone to failure.

Another problem of the known ventilation flaps is that they scotch in operation by the passing air or the vapors. The sooting often causes the flap to stick so that it can no longer be properly aligned or even moved.

It is therefore the object of the present invention to provide a cooking appliance with an improved possibility for ventilation of the cooking chamber. The possibility for ventilation of the cooking chamber should preferably be less susceptible to interference for bonding and in particular can also be implemented particularly inexpensively or economically.

The FIG. 1 shows an inventive cooking appliance 1, which is designed here as a baking oven 100. The cooking appliance 1 is provided here as a built-in appliance. It is also possible that the cooking appliance 1 is designed as a stove or stand unit.

The cooking appliance 1 has a heated cooking chamber 11, which is surrounded by a muffle 103 here. For loading and unloading of the cooking chamber 11, the cooking appliance 1 on a front side on a feed opening 31, which is closed by a cooking chamber door 21.

For the heating of the cooking chamber 11 different heating devices are available. Among other things, it is possible to heat with a top and / or bottom heat, with a circulating air function, with a hot air heating source and / or with a grill function. It is also possible that the cooking appliance 1 is designed as a combined appliance with a microwave function and / or a steam cooking function.

The cooking appliance 1 here comprises a control device 104 for controlling or regulating device functions and operating states. In addition, various operating modes and preferably different program operating modes and automatic functions can be executed here via the control device 105.

To operate the cooking appliance 1, an operating device 101 is provided. For example, the operating mode, the operating temperature and / or a program operating mode or automatic function can be selected or set via this.

The cooking chamber 11 is equipped with a not visible here arranged ventilation opening 2, via which the cooking chamber 11 in certain operating conditions selectively vented or a Wrasen can be removed. The ventilation opening 2 comprises z. B. a recess in the muffle 103, so that a flow connection between the cooking chamber 11 and the environment of the cooking device 1 is produced. Preferably, there is an active air duct, in which the air is sucked out of the cooking chamber 11 by means of a blower device through the ventilation opening 2 and / or blown.

In order to enable automated closing or opening of the ventilation opening 2, here a closure element 3 is provided, which is movable by an actuating device 4. The closure element 3 is z. B. formed as a flap or lid. The actuator 4 can pivot the closure element 3 here in different positions.

The air flow may be conducted before and / or after passing through the vent opening 2 through at least one catalyst device 102, not shown here. The catalyst device 102 is z. B. arranged below the closure element 3 and the ventilation opening 2. Thus, the air flow rate through the catalyst device 102 based on the actuator 4 and the closure element 3 is adjustable. With the catalyst device 102 is a reduction odorous substances of the air or Wrasens. However, it is also possible that the ventilation opening 2 is separated from a flow connection for the catalyst device 102. Then, the cooking chamber 11 in particular a separate opening for the removal of vapor.

Here, the closure element comprises a survey 5. In this case, the closure element 3 slides on the survey 5, when it is moved to close or open the vent opening.

The FIG. 2 shows an air guide lower part 51 of a cooking appliance 1 according to the invention with components arranged thereon. In the air guide lower part 51, the ventilation opening 2 of the cooking chamber 11 is arranged here. Below the air guide lower part 51 is the muffle 103, not shown here. On the air guide lower part 51, the actuating device 4 and the closure element 3 are arranged here.

The ventilation opening 2 is here part of a catalyst channel, which is arranged above a catalyst device. Thus, through the vent 2, the exiting the catalyst, purified air can be selectively dissipated.

The air guide lower part 51 serves as a support section 6, on which the closure element 3 slides with the elevation 5. The closure element 3 is thus located here with its elevation 5 on the support portion 6. The elevation 5 is formed here as a stamping 15, which is incorporated in the closure element 3. Here, the elevation 5 is annular and circumferentially closed in an edge region 25 of the closure element 3. The closure element 3 is formed here as a flap 63.

In the closure element 3, a passage opening 53 is arranged here, which is surrounded by the elevation 5.

The closure element 3 is shown in an open position in which the ventilation opening 2 is almost completely released. For this purpose, the closure element 3 was pivoted from the ventilation opening 2 to the air guide lower part 51. The position shown here may correspond to a position in which the ventilation opening 2 is released as far as intended. But it can also be provided a position in which the closure element 3 is pushed further from the vent opening 2 and in which the vent 2 is fully released.

To move the closure element 3, an actuating device 4 with an electric drive device 14 and, for example, an electric motor is provided here. For pivoting the closure element 3, the rotational movement of the drive device 14 is converted by means of a gear 8 in a pivoting movement.

For this purpose, the transmission device 8 here comprises a coupling gear 18. The coupling gear 18 here comprises a link 18, which is rotatably mounted on a crank 38. The crank 38 is rotated by the drive device 14. The handlebar 28 is also rotatable on one Swivel arm 48 attached. In addition, the coupling mechanism 18 comprises a pivot bearing 58, which connects the pivot arm 48 rotatably to the air guide lower part 51. The pivot arm 48 is provided by the closure element 3 and is here formed integrally with the lid 63. The closure element 3 moves in a certain radius about the axis of the pivot bearing 58th

By the coupling mechanism 18 shown here, the closure element 3 can be pivoted open and closed, without a change of direction of the drive device 14 is necessary. But it can also be a reversal of direction of the drive device 14 may be provided.

The movement of the closure element 3 in different positions can also be done with a different from the transmission device 8 shown here. For example, a linear displacement can be provided, for example with a rack device or a spindle device.

The FIG. 3 shows the cooking appliance 1 of FIG. 2 with a partially closed ventilation opening 2. In this case, the closure element 3 completely covers the ventilation opening 2. However, the passage opening 53 is located above the ventilation opening 2, so that an air flow defined by the size or shape of the passage opening 2 can take place.

Due to the annularly closed elevation 5, which completely surrounds the passage opening 53, the flow of false air is prevented. For this purpose, the elevation 5 in the position shown here lies completely preferably sealingly on the support section 6 or the air guide lower part 51. Thus, the air in this position can only flow through the passage opening 53 and not between the closure element 3 and the air guide lower part 51.

The actuating device 4 is shown here without the drive device 14. As a result, a sensor device 9 can be seen particularly well, which serves to monitor the position of the closure element 3. The sensor device 9 here comprises a coding element 19 and a sensor 29. The coding element 19 is designed as a coding disk, which is fastened in a rotationally fixed manner to the drive device 14 and / or the crank 38. As a result, the coding element 19 is movable or rotatable relative to the movement of the closure element 3.

The coding element 19 is here equipped with a coding or screening which codes several specific angles of rotation and thus specific positions of the closure element 3. On the basis of the position of the coding element is thus clearly the position of the closure element 3 can be read. The sensor 29 is used to scan the coding element 19. The sensor 29 is preferably connected to the actuating device 4 and / or the control device 104 operatively connected so that specific specific rotation angle or positions of the closure element 3 can be controlled.

In the FIG. 4 is a section of the cooking device 1 of FIG. 3 shown, which lies in the area of the ventilation opening 2. The area is shown here in a sectional side view. Here is particularly easy to see how the closure element 3 in the in FIG. 3 shown position above the vent opening 2 and the air guide lower part 51 is located. Here it is particularly easy to see that due to the adapted radii of the embossment 15, the closure element 3 can slide particularly well over the ventilation opening 2, without being misjudged.

The passage opening 53 is here above the ventilation opening 2, so that air can flow through the passage opening 53. Otherwise, the ventilation opening 2 is completely covered by the closure element 3. In this case, the survey is 5 ring-like and sealing on the support section 6 at.

In the embodiment shown here, the closure element 3 is equipped with a further elevation 35, which surrounds the passage opening 53 ring-like and circumferentially closed. The further survey 35 is formed, for example, as a stamping. For example, the further elevation 35 is equipped as a punched hole with a stamping edge, the stamping edge providing the elevation 5.

The FIG. 5 shows the cooking appliance 1 with a fully closed vent opening 2. For this purpose, the closure element 3 is here completely pushed over the vent opening 2. In addition, the passage opening 53 is arranged outside of the ventilation opening 2. As a result, no air can flow through the passage opening 53.

The FIG. 6 shows a section of the in the FIG. 5 shown cooking appliance 1 in a sectional side view. Here it is particularly easy to see that the passage opening 53 is also arranged above the support section 6. In this case, the further survey 35 sealingly abuts on the support section 6. As a result, the further elevation 35 prevents air from the region of the ventilation opening 2 from flowing between the closure element 3 and the support surface 6 and exiting through the passage opening 53 from there. An undesirable escape of air and thus a disadvantageous energy loss are thereby reliably avoided.

The FIGS. 7 and 8 show the closure element 3 in a perspective view from below or from above. The annularly closed and arranged in the edge region 25 elevation 5 is particularly well recognized here. It is also easy to see that the survey 5 is formed as an embossment 15. The closure element 3 here is a sheet metal part into which the elevation 5 has been embossed. Good to see here is also the through hole 53 and its peripheral and annular closed further survey 35. Preferably, the through hole 53 and the other survey 35 are made by a stamping process.

The one-piece design of the closure element 3 as a flap 63 with a pivot lever 48 can be seen particularly well here. For connection of the pivot arm 48 and the Schenklager 58 here corresponding recesses and, for example, holes in the pivot arm 48 are provided. For particularly space-saving pivoting of the pivot arm 48 is angled here.

The invention presented here offers a particularly advantageous regulation of an air flow rate through a ventilation opening 2, for example for a catalytic converter. For this purpose, a closure element 3 is preferably mounted above the catalyst, which can be moved in at least three positions. The positions preferably include a complete closure of the ventilation opening 2, the flow of a certain amount of air and the almost complete opening of the ventilation opening 2.

In this case, the closure element 3 presented here with its elevation 5 offers particularly few points of contact with the air-guiding lower part 51. As a result, the noise formation and the contact surface can be reduced particularly advantageously. This ensures that resistance to the movement is kept as low as possible in the event of sooting or sticking due to contamination. In addition, the survey offers the advantage that the closure element 3 can close the ventilation opening 2 in the closed state particularly well and substantially airtight. In addition, in the position in which a defined amount of air to flow, a pull of false air is avoided. By the survey and in particular the embossment is also ensured that no deformations occur, which could lead to the fact that the closure element 30 discards and tilted in the ventilation opening 2 and the catalyst channel.
