Insert for a downdraft extractor
An insert for a downdraft extractor includes a removable filter element for filtering a stream of cooking fumes, and a removable collecting element for receiving liquids. The collecting element has at least one wall which serves as a flow directing surface for deflecting the stream of cooking fumes.
1. An insert for a downdraft extractor, the insert comprising:
a filter element for filtering a stream of cooking fumes; and
a collecting element for receiving liquids, wherein the filter element and the collecting element are detachably joined together via a connecting structure, wherein the collecting element has at least one wall providing a flow conducting surface for deflecting the stream of cooking fumes, wherein the at least one wall is at least one of curved and oblique at least in regions.
2. The insert as claimed in claim 1 , wherein the collecting element and the filter element are configured to be joined together in a form-locking manner, the connecting structure comprising a filter element surface of the filter element engaging a collecting element surface of the collecting element to detachably connect the filter element to the collecting element.
3. The insert as claimed in claim 1 , wherein the at least one wall is an inner wall of the collecting element facing in a direction of a cooking fume outlet opening of the collecting element, wherein the inner wall is substantially edge-free.
4. The insert as claimed in claim 1 , wherein the filter element and the collecting element can be joined together such that a wall of the filter element and the at least one wall of the collecting element form a substantially edge-free flow conducting surface for deflecting the stream of cooking fumes, the substantially edge-free flow conducting surface being located opposite a cooking fume outlet opening of the collecting element.
5. The insert as claimed in claim 1 , wherein guide means are provided on an outer side of at least one of the collecting element and the filter element and lead to a self-centering design of at least one of the collecting element and the filter element.
6. The insert as claimed in claim 1 , wherein the filter element has at least one filter layer which is arcuate relative to a horizontally oriented axis, the filter element comprising an arcuate filter element portion, the collecting element comprising an arcuate collecting element portion.
7. The insert as claimed in claim 1 , wherein at least one of the filter element and the collecting element is formed at least in regions from plastic, the filter element comprising a filter element frame, the filter element frame being in contact with the collecting element.
8. The insert as claimed in claim 1 , wherein at least one signal-emitting element is arranged on at least one of the filter element and the collecting element.
9. The insert as claimed in claim 1 , wherein the collecting element has a cooking-fume outlet opening in which at least one flow conducting element is arranged.
10. The insert as claimed in claim 9 , wherein the filter element comprises a filter element longitudinal axis, the collecting element comprising a collecting element longitudinal axis, the collecting element longitudinal axis being parallel to the filter element longitudinal axis.
11. The insert as claimed in claim 1 , wherein the at least one wall forms an outer wall of a flow channel for the stream of cooking fumes.
12. A downdraft extractor, comprising:
a removable insert comprising a filter element for filtering a stream of cooking fumes and a collecting element for receiving liquids, wherein the filter element and the collecting element are configured to be joined together, wherein the collecting element has at least one wall providing a flow conducting surface for deflecting the stream of cooking fumes, wherein the at least one wall is at least one of curved and oblique at least in regions, wherein at least one of the filter element and the collecting element in an inserted state form part of a flow channel for the stream of cooking fumes and wherein the collecting element comprises a wall defining a transition from the collecting element to the flow channel, the wall comprising an arcuate portion and the wall being substantially edge-free.
13. The downdraft extractor as claimed in claim 12 , further comprising a removable maintenance trough.
14. The downdraft extractor as claimed in claim 12 , wherein the collecting element in an inserted state rests at least in regions on a maintenance trough.
15. The downdraft extractor as claimed in claim 12 , further comprising a maintenance trough which is able to be taken out.
16. The downdraft extractor as claimed in claim 12 , wherein the collecting element comprises a cooking-fume outlet opening and an interior space in fluid communication with the cooking-fume outlet.
17. The downdraft extractor as claimed in claim 12 , wherein the filter element comprises a filter element longitudinal axis, the collecting element comprising a collecting element longitudinal axis, the collecting element longitudinal axis being parallel to the filter element longitudinal axis.
18. A hob system, comprising:
at least one hob; and
at least one downdraft extractor comprising a removable insert, the removable insert comprising a filter element for filtering a stream of cooking fumes and a collecting element for receiving liquids, wherein the filter element and the collecting element are configured to be joined together, wherein the collecting element has at least one wall providing a flow conducting surface for deflecting the stream of cooking fumes, wherein the at least one wall is at least one of curved and oblique at least in regions and the filter element and the collecting element are configured to be joined together such that a wall of the filter element and a wall of the collecting element form a substantially edge-free flow directing surface for deflecting the stream of cooking fumes in a direction of a cooking fume outlet of the collecting element.
19. The hob system as claimed in claim 18 , wherein the filter element comprises a filter element longitudinal axis, the collecting element comprising a collecting element longitudinal axis, the collecting element longitudinal axis being parallel to the filter element longitudinal axis, the filter element comprising an arcuate filter element portion, the filter element comprising a filter element surface, the collecting element comprising a collecting element surface, the filter element surface cooperating with the collecting element surface to define at least a portion of a connecting structure, the collecting element being detachably connected to the filter element via the connecting structure.
