Cooking device and method for operating

Description

[0001] The present invention relates to a cooking device, in particular a steam cooking device, preferably for integration into a furniture front, comprising at least one device body including at least one cooking chamber, at least one blower device, at least one air discharge section with at least one air discharge opening for blowing air and / or vapors out of the device body, and at least one duct system for guiding at least air and / or vapors. The duct system includes at least one valve device, wherein the valve device is movable into at least a first and at least a second valve position. The present invention also relates to a method for operating a cooking device.

[0002] A variety of different cooking appliances, such as ovens, microwave ovens, and / or steam ovens with a cooking chamber for cooking food and / or groceries, have become known, which can be integrated, in particular, into a furniture front, e.g., of a kitchen unit. For example, from the publications EP 3 029 382 A1, EP 3 437 477 A1, EP 3 437 478 A1 and DE 10 2019 216343 A1.

[0003] Such known cooking appliances often have at least one ventilation system to remove air and / or steam, at least partially, from the cooking chamber before, during, and / or after operation, and in particular to discharge it into the surrounding area. For this purpose, the ventilation systems of known steam cooking appliances regularly include at least one fan and / or at least one flow geometry, such as a Venturi nozzle, to draw air and / or steam or vapors from the cooking chamber and thus, for example, prevent the formation of overpressure in the cooking chamber, regulate the warm air and / or humidity content in the cooking chamber, and / or mix the extracted air and / or steam with fresh air.

[0004] Such well-known cooking appliances with a ventilation system generally operate reliably. However, a disadvantage of these systems is that their ventilation systems often do not allow for sufficient and / or satisfactory air circulation within the cooking chamber, especially within a short timeframe. This means that a virtually complete exchange and / or complete removal of the air, fumes, and / or steam present in the cooking chamber is usually not possible. Often, this can only be achieved by using or installing powerful fans, which not only require a large or even very large installation volume but also regularly involve considerable costs.

[0005] It is therefore the object of the present invention to provide a cooking device which enables efficient removal of air and / or steam from the cooking chamber in various operating situations, particularly with a compact design and / or gentle operation of the cooking device.

[0006] This problem is solved by a cooking device having the features of claim 1 and a method for operating a cooking device having the features of claim 13.

[0071] Further advantages and features of the present invention will become apparent from the exemplary embodiments, which are explained below with reference to the accompanying figures.

[0072] The figures show: Figure 1 is a purely schematic representation of an embodiment of a cooking device according to the invention in a sectional view from above; Figure 2 is a purely schematic representation of another embodiment of a cooking device according to the invention in a sectional view from above; Figure 3 is a purely schematic representation of another embodiment of a cooking device according to the invention in a sectional view from above; Figure 4 is a purely schematic representation of an embodiment of a cooking device according to the invention in a perspective view; and Figure 5 is a purely schematic representation of another embodiment of a cooking device according to the invention in a perspective view.

[0073] In Figure 1 The figure shown is a purely schematic embodiment of a cooking device 1 according to the invention in a sectional view from above.

[0074] The cooking device 1 here has a basic unit 2, which here includes a cooking chamber 3, a blower unit 4 and an air discharge section 5 with an air discharge opening 6 for blowing air and / or vapors out of the basic unit 2.

[0075] The cooking device 1 is designed here as a steam cooking device 100, whereby water vapor can be provided in the cooking chamber 3 for cooking food by means of a steam source.

[0076] In the embodiment shown here, the cooking chamber 3, the blower device 4 and the air outlet opening 6 are connected by means of a channel guidance system 7 encompassed by the device base body 2 for the purpose of guiding air and / or vapors.

[0077] The duct system 7 comprises a discharge duct 12 for removing air and / or steam from the cooking chamber 3 and an injection duct 13 for blowing an airflow provided by the blower unit 4 into the cooking chamber 3. Furthermore, the duct system 7 comprises a venturi nozzle unit 8, a valve unit 9, and an air supply duct 15 for supplying air to the valve unit 9.

[0078] The valve assembly 9 has three connection sections 20, one of which is operatively connected to the air supply channel 15, another to the injection channel 13 and another to the venturi nozzle assembly 8.

[0079] The air supply duct 15 connects the blower unit 4 and the valve unit 9, i.e., a connection section 20 of the valve unit 9, so that the blower unit 4 and the valve unit 9 are operatively connected via the air supply duct 15. Thus, the blower unit 4 can provide an airflow in the duct system 7.

[0080] For this purpose, the blower unit 4 draws in air or fresh air from the surroundings of the device body 2 and blows the drawn-in fresh air into the air supply duct 15. Consequently, the flow direction of the airflow provided by the blower unit 4 in the duct system 7 is directed away from the blower unit 4.

[0081] The injection channel 13 connects the cooking chamber 3 and the valve assembly 9, i.e., a connection section 20 of the valve assembly 9, so that the valve assembly 9 and the cooking chamber 3 are in operative communication by means of the injection channel 13.

[0082] In the illustrated embodiment, the Venturi nozzle assembly 8 and the valve assembly 9, i.e., a connection section 20 of the valve assembly 9, are connected via a connecting channel 19, so that the valve assembly 9 and the Venturi nozzle assembly 8 are operatively connected by means of the connecting channel 19. Depending on the application and design, the valve assembly 9 can also be directly connected to the Venturi nozzle assembly 8.

[0083] In the illustrated embodiment, the discharge channel 12 connects the cooking chamber 3 and the venturi nozzle device 8, so that the cooking chamber 3 and the venturi nozzle device 8 are operatively connected by means of the discharge channel 12.

[0084] In the embodiment shown here, the discharge channel 12, the injection channel 13, the air supply channel 15 and the connecting channel 19 each provide a flow guide channel 14 for guiding a fluid, such as air, vapors, liquid and / or condensate.

[0085] In the illustrated embodiment, the Venturi nozzle assembly 8 is designed and configured to draw in air and / or steam from the cooking chamber 3 using the airflow provided by the blower assembly 4 and to direct it to the air outlet opening 6. Here, the Venturi nozzle assembly 8 is provided by the air outlet section 5, such that, in the illustrated embodiment, the valve assembly 9 is arranged upstream of the Venturi nozzle assembly 8 in the direction of flow of the airflow provided by the blower assembly 4. The air outlet section 5 provides a flow guide channel for guiding a fluid in sections.

[0086] In the embodiment shown here, the valve assembly 9 can be moved into a first and a second valve position 10, 11. In the first valve position 10, the valve assembly 9 provides an effective connection between the air supply channel 15 and the Venturi nozzle assembly 8 via the connecting channel 19. Thus, an airflow supplied by the blower assembly 4 in the air supply channel 15 can be directed via the connecting channel 19 into the Venturi nozzle assembly 8.

[0087] In the second valve position 11, the valve assembly 9 provides an effective connection between the air supply duct 15 and the injection duct 13. Thus, an airflow supplied by the blower assembly 4 in the air supply duct 15 can be directed into the cooking chamber.

[0088] Thus, the valve device 9 is suitable and designed to direct an airflow provided by the blower device 4 in the air supply channel 15 either into the venturi nozzle device 8, so that air and / or vapors from the cooking chamber 3 can be drawn in via the discharge channel 12 to the venturi nozzle device 8 and discharged via the air outlet opening 6, or into the cooking chamber 3, so that air and / or vapors from the cooking chamber 3 can be blown out via the discharge channel 12 and the air outlet section from the air outlet opening 6.

[0089] Thus, the cooking chamber 3, the blower unit 4 and the air outlet opening 6 are interconnected by means of the duct system 7 in such a way that in the first valve position 10 air and / or vapors can be drawn from the cooking chamber 3 and in the second valve position 11 air and / or vapors can be blown out of the cooking chamber 3.

[0090] Thus, according to the inventive method for operating a cooking device 1, the valve device 9 can be moved to the first valve position 10 in order to draw air and / or steam from the cooking chamber 3 via the discharge channel 12 to the Venturi nozzle device 8 and discharge it from the air outlet opening 6, or the valve device 9 can be moved to the second valve position 11 in order to blow air and / or steam from the cooking chamber 3 via the discharge channel 12 out of the air outlet opening 6.

[0091] In Figure 2 A further embodiment of a cooking device 1 according to the invention is shown schematically in a sectional view from above. The cooking device 1 is here designed as a steam cooking device 100.

[0092] As in Figure 1 The cooking device 1 also features in Figure 2a basic unit body 2, which here comprises a cooking chamber 3, a blower unit 4, an air discharge section 5 with an air discharge opening 6 and a duct system 7.

[0093] Here too, the channel guidance system 7 includes a discharge channel 12, an injection channel 13, a venturi nozzle device 8, a valve device 9 and an air supply channel 15.

[0094] Unlike Figure 1 In the embodiment shown here, the Venturi nozzle assembly 8 is designed as a separate component. The Venturi nozzle assembly 8 is connected to the air discharge section 5 via an outlet channel 17, so that the Venturi nozzle assembly 8 and the air discharge section 5 are operatively connected by means of the outlet channel 17.

[0095] Furthermore, the valve assembly 9 is designed here as a 3 / 2-way valve element 16, which has three connection sections 20 and can be moved into a first and a second valve position 10, 11. The 3 / 2-way valve element 16 allows two of the three connection sections 20 to be operatively connected to each other in valve positions 10, 11.

[0096] In the embodiment shown here, the valve assembly 9 is moved to the second valve position 11. Thus, the valve assembly 9 provides an effective connection between the air supply channel 15 and the injection channel 13.

[0097] Thus, as schematically indicated by arrows, an airflow provided by the blower device 4 in the air supply channel 15 can be directed into the cooking chamber 3, so that air and / or vapors from the cooking chamber 3 can be blown out via the exhaust channel 12 as well as the venturi nozzle device 8 and the air discharge section 5 from the air discharge opening 6.

[0098] Consequently, according to the inventive method, the valve device 9 can be moved to the second valve position 11 in order to blow air and / or steam out of the cooking chamber 3.

[0099] In Figure 3 This is a purely schematic embodiment of a cooking device 1 according to the invention. Figure 2 shown, where here in contrast to Figure 2 The valve assembly 9 is moved here to the first valve position 10.

[0100] In the embodiment shown here, the valve assembly 9 thus provides an operative connection between the air supply channel 15 and the venturi nozzle assembly 8.

[0101] Thus, as schematically indicated by arrows, an airflow provided by the blower device 4 in the air supply channel 15 can be directed into the venturi nozzle device 8, so that air and / or vapors from the cooking chamber 3 can be drawn to the venturi nozzle device 8 via the discharge channel 12 and discharged via the air outlet section 5 and the air outlet opening 6.

[0102] Consequently, according to the inventive method, the valve device 9 can be moved to the first valve position 10 in order to draw air and / or steam out of the cooking chamber 3.

[0103] In Figure 4The following is a purely schematic embodiment of a cooking device 1 designed as a cooking drawer device 200 according to the invention, shown in a purely schematic perspective view.

[0104] The cooking drawer device 200 provides a steam cooking device 100 and, in the illustrated embodiment, comprises a device base body 2, a furniture front element 201 and a relocation device 202.

[0105] As in Figure 1 The basic unit 2 comprises a cooking chamber 3, a blower unit 4, an air discharge section 5 with an air discharge opening 6 and a duct system 7 not shown in detail here.

[0106] In the embodiment shown here, the furniture front element 201 is arranged on a front side of the appliance base body 2, which here faces a user of the cooking drawer device 200 in a usual operating and installation position of the cooking device 1.

[0107] By means of the relocation device 202, the device base body 2 can be relocated here in a frame device between a retracted position or storage position and an extended position or handling position.
