Definitions

  • the present patent application for industrial invention relates to a suction unit intended to be installed underneath a cooktop.
  • the invention also extends to the cooktop equipped with the suction unit according to the invention.
  • the peculiarity and advantages of the invention will become more apparent following a brief description of the prior art and the related drawbacks.
  • the suction unit is arranged underneath the cooktop, on which a suction opening is provided, close to the burners.
  • This design solution is characterized in that the suction mouth of the suction unit (G) is not vertically aligned with the suction aperture (F) placed on cooktop (P).
  • the air current (A) crosses the motor (M) of the electric fan (E) performing an effective cooling thereof, by virtue of which using powerful motors capable of processing large suction flow rates becomes possible.
  • a further drawback relates to the fluid-dynamic efficiency, since the misaligned arrangement of the suction unit (G) with respect to the suction aperture (F) imposes a path with multiple direction changes and multiple impacts on the intake air current, resulting in the generation of turbulence and efficiency loss.
  • the present invention precisely comes from the discussion of the above-indicated and commented prior art, the purpose of which is to provide a cooktop with an subservient suction unit which borrows all the merits of the known design solutions, without however being penalized by the limitations or drawbacks thereof.
  • the suction unit (100) comprises an electric suction fan (10), a filtration cartridge (20), a water collection and discharge tank (30), a casing (40).
  • the suction unit (100) mentioned is intended to be installed underneath a cooktop (200).
  • the electric suction fan (10) has a conventional construction setup and comprises a scroll-shaped housing (112) in which an impeller (13) is housed, practically consisting of a cylindrical paddled drum adapted to draw air and centrifuge it in the snail-shaped diffuser duct (18), which surrounds the impeller (13) and ends with a delivery mouth (14).
  • said scroll-shaped housing (112) comprises a pair of half-shells, one being the upper half-shell (11), the other being the lower half-shell (12), interfaced and connected to each other by means of screws.
  • Said diffuser duct (18) is defined by the side walls of said half-shells (11 and 12), on the bottom walls of which respective circular mouths (11a and 12a) are provided instead, being coaxial to each other and to the vertical rotation axis (Y) of said impeller (13).
  • Said impeller (13) is mounted to the vertical shaft of an electric motor (15) housed inside the impeller (13) and supported by a U-bolt fastened in the middle of the circular mouth (12a) of the lower half-shell (12), closed by a grating cover (16), which shields said motor (15) without hindering the flow of air drawn by the impeller (13).
  • the suction unit (100) comprises a collection and discharge tank (30) for any water accidentally fallen onto the cooktop (200), and from the latter poured into the underlying compartment, passing through the aperture (201) obtained on the cooktop (200), in order to allow the suction of the air and fumes by the electric fan (10) placed underneath the cooktop (200).
  • Said tank (30) preferably having a rectangular shape in top view, has a bottom wall (31) and four lateral flanks (32, 33, 34, 35) adapted to delimit a watertight compartment (30a).
  • Three (32, 33 and 34) of these lateral flanks are characterized by the box-like structure thereof, meaning that their section with a transverse plane has an upside-down "U"-shaped profile.
  • these three box-like flanks (32, 33 and 34) have respective inner gaps (36), all intercommunicating with one another, where each gap (36) is laterally delimited by the opposing and parallel pair of two vertical segments of said upside-down U-shaped section, while it is closed at the top by the horizontal wing joining said pair of vertical segments.
  • a further feature of said tank (30) is that the three box-like flanks (32, 33 and 34) thereof have a series of windows (37) placed side-by-side, through which said gaps (36) are intercommunicated with said inner compartment (30a) of tank (30).
  • each window (37) is at a higher height than the bottom plane (31) of tank (30), whereby the water poured into the compartment (30a) cannot overflow from said windows (37), at least as long as the level thereof does not exceed the height at which lies said lower edge (37a).
  • the electric fan (10) is fixed underneath the tank (30) so that the bottom wall (31) of tank (30) overlaps/covers the circular mouth (11a) of the upper half-shell (11), as shown in Figures 5 and 6 .
  • attention is to be paid so that the non-box-like flank (34) of tank (30) is placed towards and above the aforesaid delivery mouth (14) of the electric fan (10), as shown in Figure 7 .
  • the suction unit (100) also comprises an airtight casing (40) practically shaped like a parallelepiped box, the side walls (41) of which enclose said electric fan (10) therein, the delivery mouth (14) of which is centered in a suitable and alike opening (42) obtained at one of said side walls (41), as shown in Figure 8 .
  • Said casing (40) is fixed underneath said tank (30), which has a peripheral baseboard (30b) having shape and size such as to be coupled to the upper mouth of said casing (40) in a perfect manner, the inner compartment (40a) of which remains intercommunicating only with the three overlying gaps (36) of the three box-like flanks (32, 33 and 34).
  • said tank (30) is fixed underneath the cooktop (200) so that said aperture (201) is centered with respect to the inner compartment (30a) of tank (30), where a filtering cartridge (20) is housed, which can be removed from such a compartment (30a) by passing it through the same aperture (201) after the removal of the related closing grating (202).
  • the arrows (F1) in Figure 4 indicate the trajectory of the path followed by the intake air current, which from cooktop (200) reaches and crosses the electric fan (10), while the arrows (F2) indicate the trajectory of the path followed by the water which could accidentally precipitate from cooktop (200) into the aperture (201).
  • the intake air current pours through the aperture (201) into the compartment (30a) of tank (30), from where it exits, after passing the filtering cartridge (20), through the windows (37), pouring into the gaps (36) and from the latter into the underlying compartment (40a) of casing (40), where the suction mouth of the electric fan (10) is located, i.e., the circular mouth (12a) of the lower half-shell (12).
  • the air current hits the electric motor (15) and is centrifuged by the impeller (13) within said snail-shaped diffuser duct (18), to finally be ejected from the delivery mouth (14), on which the delivery duct responsible for conveying the air to the outside is engaged.
  • the idea of setting up the filtering cartridge (20), the collection tank (30) and the electric fan (10) one on top of the other in a column allows limiting as much as possible the transverse dimensions of the suction unit (100) according to the invention, with the advantage of also installing it underneath small cooktops (200), while having a wide useful space for the arrangement of the burners straddling the central aperture (201).
  • Figures 9 and 10 show a construction variant of tank (30) differing from that shown in Figures 7 and 8 only in that the bottom wall (31) comprises a transverse partition (38), placed close to the aforesaid lateral flank (33) and adapted to separate two compartments, the first (VI) being larger, the second (V2) being smaller.
  • the bottom wall (31) comprises a transverse partition (38), placed close to the aforesaid lateral flank (33) and adapted to separate two compartments, the first (VI) being larger, the second (V2) being smaller.
  • the bottom wall (31) has some slots (39) at said second compartment (V2), which open into the underlying casing (40) and intercommunicate the inner compartment (30a) of tank (30) with the inner compartment (40a) of casing (40).
  • tank (30) not only may the intake air current (F1) reach the inner compartment (40a) of casing (40) through said windows (37), but also through said slots (39), by following a less winding path, and therefore with less load losses.
