Definitions

  • the present patent application refers to a kitchen cooker hood provided with a retractable extraction/filtration unit.
  • kitchen cooker hoods comprise a metal housing that contains the air extraction unit and the set of filters used to purify the air sucked inside the cooker hood.
  • the housing is closed by a lower wall provided with a grate that allows air circulation.
  • the grate is sometimes obtained by providing a dense, closely spaced series of small through slots on the lower wall; in other cases, the same grate is obtained by introducing grated panels in suitable openings provided on the lower wall.
  • the air extracted from the cooktop penetrates into the housing through the grated lower wall and passes through the set of filters installed immediately below the grated lower wall.
  • the said drawback is related to the use of the grated lower wall and has a twofold practical effect.
  • Another limitation of the traditional technology is related to the necessity to use the said standardised solution (i.e. adoption of the grated lower wall), which limits the designer's freedom when creating original innovative shapes that would be well received by demanding customers.
  • the main purpose of the present invention is to devise a kitchen cooker hood in which the metal housing with traditional configuration is characterised by the presence of a lower wall with closed, continuous surface (without grate), free from the drawbacks that are directly related with the use of traditional grated walls.
  • the cooker hood of the invention comprises a retractable extraction/filtration unit, capable of varying its position according to the working or idle state of the hood.
  • the said extraction/filtration unit consists in a box-shaped body with reduced height and slightly lower base compared to the lower wall of the housing.
  • the said box-shaped body is closed by a completely closed lower wall, while the vertical borders on the perimeter sides are provided with a dense, closely series of through slots, with traditional air filters installed behind them.
  • the said box-shaped body is housed inside a corresponding space in the lower part of the housing, which communicates with the traditional plenum chamber of all cooker hoods.
  • the said extraction-filtration unit is able to slide vertically, from an idle position in which it is exactly contained inside its housing, to a working position in which it protrudes below the lower continuous lower wall that closes the housing.
  • the extraction-filtration unit projects from its housing with a short downward travel, in such a way that its grated perimeter sides are brought under the lower wall of the housing, in order to extract the air loaded with fumes from the cooktop.
  • the extraction-filtration unit is internally provided with grated surfaces, downstream the set of filters; in this way, after passing through the said filters, the extracted air is conveyed towards the plenum chamber above and finally towards the flue for final ejection into the air.
  • the extraction-filtration unit is brought back inside the housing with a short upward travel; in this way, the unit is no longer visible and the continuity and planarity of the lower surface of the housing are restored.
  • the cooker hood of the invention (1) traditionally comprises a metal housing (2) with any shape and size, provided on top with a vertical tubular element (3), normally designed to act as plenum chamber, in which a traditional fan (4) operates; it being traditionally provided that the plenum chamber (3) is connected to a flue (5) to eject fumes into the air.
  • the housing (2) is closed by a lower wall (2a) with continuous surface, with a space in perfectly aligned position with the plenum chamber (3) that exactly contains a special extraction-filtration unit (6) with box-shaped structure in horizontal position.
  • the filtration unit (6) is closed by a lower closed wall (6a) and is enclosed by short vertical perimeter walls (6b) with basically grated configuration, being provided with a dense, closely spaced series of slots.
  • the same extraction-filtration unit (6) is provided with a niche (7) with upward opening enclosed by vertical walls (7a) with grated structure, which structurally correspond to the said external grated walls (6b).
  • the peculiarity of the extraction-filtration unit (6) consists in the fact that it can make short vertical alternated travels, in parallel direction to its axis, by means of traditional actuators (not shown in the enclosed figures).
  • the extraction-filtration unit (6) makes a short downward travel and protrudes in its entire height from the space in which it is housed, as shown in figure 2.
  • the perimeter grated walls (6b) extract suck the air coming from the cooktop (PC) into the hood (1).
  • the air extracted through the external grated walls (6b) passes through the traditional set of filters situated behind the said walls and is evacuated upwards, towards the plenum chamber (3) through the internal grated walls (7a) that surround the niche (7) of the same extraction-filtration unit (6); this fact can be exactly verified based on the crossed examination of figures 2 and 3 and relevant flow arrows.
  • the housing (2) incorporates several retractable extraction-filtration units (6), possibly one for each burner of the cooktop.
  • the spaces that house the multiple retractable extraction-filtration units (6) must be in communication with the plenum chamber (3) traditionally provided above the housing (2).
  • the traditional set of filters is situated inside the plenum chamber (3), and not inside each retractable extraction unit (6).
