- the present invention relates to a hood for extraction and filtration of gases from home kitchens.
- hoods are traditionally known as extractor or filter hoods depending on whether they exhaust air outside of the room in which the hood is installed, using an appropriate extractor or an electrically powered motor fan unit, or recirculate air into the same room, once polluting substances have been filtered out.

Abstract
Description
- The present invention relates to an improved filter hood as defined in the preamble of
claim 1. - Particularly, the present invention relates to a hood for extraction and filtration of gases from home kitchens.
- Domestic hoods are traditionally known as extractor or filter hoods depending on whether they exhaust air outside of the room in which the hood is installed, using an appropriate extractor or an electrically powered motor fan unit, or recirculate air into the same room, once polluting substances have been filtered out.
- Typically, most of currently manufactured hoods can accomplish either function according to the state assigned to a switch device, which can be selectively actuated by the user or installer of the hood.
- Concerning the filter function, prior art hoods are normally equipped with grease filters and, if they are mounted in a filtering configuration, with activated carbon filters. The former are specially designed to separate the liquid or solid particles suspended in the gases collected by the hood. The latter filter polluting gases or fumes out of the collected gases.
- In terms of construction, these filters are usually arranged on the intake duct of the extractor. Also, they are mounted in series-arrangement for gases to be intercepted first by the grease filter and then by the activated carbon filter.
- The use of such traditional filter arrangement generates turbulence and vortexes in gas flow, which are of great disturbance to the fluid-dynamic operation of the extractor. This causes both energy dissipation in the gas flow and perturbation of the state in which the gas flow enters the filter surface. Due to this perturbation, certain parts of the working surface of the filter have to deal with a larger amount of gases, and other parts of the filter deal with a weaker gas flow.
- This uncontrolled fluid dynamics is unfavorable for a number of reasons including: generally reduced energy efficiency of the hood; high level of sound emissions during operation of the hood; uneven filtering conditions, which both affect filtration efficiency and cause irregular and uneven exhaustion of the activated carbons contained in the filter; low collection of fumes from the coolctop.
- These drawbacks are aggravated in so-called T-shaped hoods. In such T-shaped hoods, the extractor is laterally displaced relative to the filters, due to the off-center position of the intake duct that accommodates the extractor.
- This construction arrangement aggravates the problem of uneven distribution of gas extraction rate on the filters, a higher rate being found in the portion of the filter that directly faces the suction port of the extractor, and a lower extraction rate being found in the adjacent portion of the filter.
-
US 6,235,090 discloses a hood having a filter and louvers overlapping the entire surface of the filter. These louvers are maintained in position by the passage of gases until the hood needs cleaning. Therefore, the louvers are movable, but their use generates turbulence and vortexes in gas flow, which are of great disturbance to the fluid-dynamic operation of the extractor. Due to this perturbation, certain parts of the working surface of the filter have to deal with a larger amount of gases, and other parts of the filter deal with a weaker gas flow. - In view of the prior art as set forth hereinbefore, the object of the present invention is to obviate the above drawbacks by providing a hood and a filtering panel for hoods, designed for improving the use of filters regardless of the extraction rate of the extractor.
- This object is fulfilled by a filter hood as defined by the features of
claim 1. - The present invention provides a hood that can establish well-defined and controlled fluid-dynamic conditions in gases, to considerably improve all the characteristic functional performances of the hood.
- The present invention also affords increased filtration efficiency, due to improved, even utilization of the filter surface.
- Furthermore, the present invention ensures improved fume collection over the entire cooktop.
- The characteristics and advantages of the invention will appear from the following detailed description of one preferred embodiment, which is illustrated without limitation in the annexed drawings, in which:
-
Figure 1 shows an external perspective view of a hood of the invention; -
Figure 2 shows a bottom perspective view of the hood of the previous figure; -
Figure 3 shows a schematic, partially sectional perspective view of the hood of the invention, with the filtering panel configuration assumed when the extractor is stopped or operates at a low extraction rate; -
Figure 4 shows a perspective view of the filtering panel of the invention, in the configuration ofFigure 3 ; -
Figure 5 shows a schematic, partially sectional perspective view of the hood of the invention, with the filtering panel configuration assumed when the extractor operates at a medium extraction rate; -
Figure 6 shows a perspective view of the filtering panel of the invention, in the configuration ofFigure 5 ; -
Figures 7A and 7B show perspective and lateral views of an element of the filtering panel respectively; -
Figure 8 shows a perspective view of the filtering device with the extractor operating at a medium extraction rate, according to the present invention. - Referring to the accompanying figures,
numeral 1 designates a filter hood for use in home kitchens, which comprises anextraction channel 2 extending in a direction of extension X-X and acollecting section 3. - Particularly referring to
Figure 2 , thehood 1 comprises afiltering device 1A inserted in thecollecting section 3. - The
filtering device 1A comprises a filtering panel (briefly referred to hereinafter as filter) 5 and asupport frame 4 in which it is inserted or contained, as is known in the art. Thefilter 5 comprises a grid, or a grid and an activated carbon panel or, instead of the activated carbon panel, a polyurethane panel, the latter as defined by the features as set forth inPCT/EP2014/055334 - Preferably, in the
filter 5 the grid overlaps the activated carbon panel, or the polyurethane panel. - Also, these elements are mounted in series-arrangement for gases to be intercepted first by the grease filter and then by the activated carbon filter, if any, or by the polyurethane panel.
- The
hood 1 comprises anextractor 6, having an electric motor 7, which is located within theextraction channel 2. - The
hood 1 as shown in the figures has a configuration that is known by hood manufacturers as T-shaped configuration. - As a result of the T shape of the hood, the
suction port 8 of theextractor 6 is placed in front to aportion 5a of thefilter 5 and itsrespective support frame 4, theremaining portion 5b of the panel being reached by the suction of theextractor 6 through aspecial channel arrangement 9. - According to the present disclosure, the portion of the
frame 4 that directly faces theinlet 8 of theextractor 6 comprises a plurality oflouvers 10 having a mainly longitudinal extension, which overlap theportion 5a of thefilter 5. - In one aspect, the
support frame 4 for thefiltering device 1A is designed as a quadrangle, and comprises two parallel and opposed pairs ofsides louvers 10 extending across one pair of said sides. - In the particular view of
Figure 8 , the plurality oflouvers 10 extend between the pair ofsides 4B. - Each
louver 10 of said plurality of louvers is mounted to freely pivot about its respective pivot (or rotation) axis Y-Y. - This axis Y-Y is preferably parallel to the longitudinal extent of the louver, between the opposed sides of the
frame 4. - Preferably, the axis Y-Y about which each
louver 10 pivots is located near one of the longitudinal edges of the louver, the other edge being spaced from the former to such an extent as to interfere with the adjacent louver. - The
louver 10 is free to pivot between a position in which it is substantially parallel to the surface of theportion 5a of thefilter 5 that faces the suction port 8 (Figures 3 and 4 ) and a position in which it is transverse to such surface, as schematically shown inFigures 5 and 6 . - Referring to
Figure 8 , it shall be noted that the freely pivotinglouvers 10 change their position in response to the suction generated by theextractor 6 and their inclined position is a function of the amount of such suction. - Preferably, the position in which each
louver 10 is transverse to the surface of theportion 5a of thefilter 5 may range from 0° to 80°, preferably from 0° to 75°, which means that it may be from substantially parallel to substantially perpendicular to the surface of theportion 5a of thefilter 5. - In other words, each
louver 10 rotates from 0° to 80° about its axis Y-Y. - Therefore, the
portion 5a of the panel of filtering material will be substantially covered by the plurality oflouvers 10, as schematically shown inFigure 3 , when theextractor 6 exerts no or very little suction and, as shown inFigure 5 , the same portion of the filtering panel will be increasingly exposed, as suction increases. - This behavior will result in a substantially even distribution of airflow extraction rate over the surface of the
filtering panel 5, and will prevent the drawback of partial or local use thefiltering panel 5. - In one aspect, when the plurality of
louvers 10 are in the position in which they are substantially parallel to the surface of theportion 5a of the filtering panel facing thesuction port 8 of theextractor 6, they cover from 30% to 75% of the area defined by thesupport frame 4. - It shall be noted, also referring to
Figure 7A , that eachlouver 10 comprises apair 10A of pivots at the ends of its mainly longitudinal direction of extension, which engage theframe 4 in such a manner as to allow thelouvers 10 to pivot relative thesupport frame 4 under the action of theextractor 6. - Preferably, according to the present disclosure and referring to
Figure 7B , the extent S of thelouvers 10 in the direction transverse to the axis Y-Y has a value that increases from thepivoting louver 10 located at theedge 5c of theportion 5a of the filtering panel facing thesuction port 8 of the extractor. - Alternatively, the louvers have the same extents S in the direction transverse to the axis Y-Y, as shown in
Figure 8 . - In one aspect, according to the present disclosure and referring to
Figure 7B , eachlouver 10 has a NACA wing profile, preferably a NACA 4415 wing profile, with its concavity facing the surface of theportion 5a of the filtering panel that faces thesuction port 8 of the extractor when eachlouver 10 is deemed to be substantially parallel to such surface. - Finally, also referring to
Figure 7A , in order to avoid noise-inducing vibrations in thelouvers 10, dampingdevices 10B are disposed on the louvers (or on the axis Y-Y about which thelouvers 10 are pivotally mounted) to limit any vibration events. - Those skilled in the art will obviously appreciate that a number of changes and variants may be made to the filter hood of the invention as described hereinbefore to meet specific needs, without departure from the scope of the invention, as defined in the following claims.
