Definitions

  • the present patent application for industrial invention relates to an optimized extraction system for a hob.
  • hobs are usually combined with air extraction devices suitable for capturing the fumes and the bad odors that are produced by the cooking vessels.
  • the hob is surmounted by an extractor hood that contains a device used for the forced extraction of the air and provided with an electric motor to actuate a fan that can operate at different revolution speeds.
  • a device used for the forced extraction of the air and provided with an electric motor to actuate a fan that can operate at different revolution speeds.
  • said device When said device is activated, the fumes and the bad odors produced during cooking are extracted inside the extractor hood, passing through a filtering unit before they are conveyed outside by means of an ordinary exhaust pipe.
  • air extraction devices with a new design have been introduced on the market.
  • Said air extraction devices are housed under the hob in such a way that, when they are activated, the fumes and the bad odors generated when cooking are extracted downwards through one or more grilles mounted on the hob, reaching the filtering unit associated with said extraction device before they are discharged outside.
  • the hob communicates with the extraction device by means of interconnecting electronic systems that inform the extraction device about the number of burners that are used from time to time, in such a way that said extraction device can consequently set the rotational speed of the fan (which can be usually selected among three or four speeds).
  • the fan of the air extraction device is rotated at the first speed; if three burners are used, then the fan is rotated at the second speed; in case of four active burners, the fan is rotated at the maximum level, i.e. the third or the fourth speed.
  • CN109990333 discloses a range hood with adjustable air input.
  • the range hood comprises a driving assembly that controls an adjusting assembly according to the current fume generating position.
  • DE102018107904 discloses a method for operating one closure element of one inlet opening of an air extraction device for a hob, wherein a hob signal is read, which represents one position of a cooking vessel and/or a number of cooking vessels set on the hob.
  • CN107525112 discloses a range hood with dual air ducts and a control system.
  • CA2872239 discloses a control of an exhaust hood system having multiple hood sections with an exhaust output fed to a common downstream.
  • the purpose of the present invention is to solve the drawbacks of the prior art by disclosing an extraction system for a hob that is optimized according to the position and the number of active burners.
  • Another purpose is to disclose an extraction system for a hob that is capable of guaranteeing the highest operating efficiency, that is to say of guaranteeing a targeted extraction action only for the burners that are active in a given moment.
  • Figs. 1, 2 and 3 illustrate an extraction system (100) according to the invention.
  • the extraction system (100) is an extraction system that operates under a hob (P).
  • the extraction device (100) is suitable for forcedly extracting the fumes downwards through grilles (21, 31) disposed in the proximity of the hob (P) near the burners.
  • the hob (P) comprises a first lateral portion (P1) and a second lateral portion (P2). Each lateral portion (P1, P2) can be considered as half of the hob relative to a central line (M) of the hob.
  • the extraction system (100) comprises a main duct (10) basically disposed with vertical axis under the hob (P).
  • a fan (40) is disposed in the main duct (10).
  • the fan (40) is actuated by an electric motor.
  • An electronic control unit (C1) controls the actuation of the electric motor of the fan (40).
  • the main duct (10) is joined with a first extraction branch (20) and a second extraction branch (30) that lead to grilles (21, 31) respectively disposed in the proximity of the first lateral portion (P1) and of the second lateral portion (P2) of the hob.
  • Each extraction branch (20, 30) is symmetrical and opposite.
  • Each extraction branch (20, 30) has a substantially L-shaped profile and comprises a horizontal portion that extends under the hob (P) in parallel direction relative to the hob, and a vertical portion that ends in correspondence of the grille (21, 31) disposed near the hob (P).
  • the first extraction branch (20) serves the first lateral portion (P1) of the hob and the second extraction branch (30) serves the second lateral portion (P2) of the hob.
  • a deflector (50) is movably mounted in a connection point (R) between the main duct (10) and the two extraction branches (20, 30).
  • the deflector (50) can be moved in three positions:
  • the deflector (50) is actuated by an actuator (6) controlled by the electronic control unit (C1).
  • the actuator (6) may be of pneumatic type and may comprise an electrovalve controlled by the electronic control unit (C1).
  • the actuator (6) may also be of electric, magnetic, or electro-magnetic type.
  • the air extraction system (100) comprises detection means (S) suitable for selectively detecting the activation of the burners disposed in the first portion (P1) and in the second portion (P2) of the hob.
  • the detection means (S) are provided in the hob (P) and may consist in temperature sensors, such as thermocouples.
  • the detection means (S) are operatively connected to the electronic control unit (C1).
  • the extraction system may also comprise a second electronic control unit (C2) connected to the detection means (S) and interfaced with the electronic control unit (C1).
  • the second electronic control unit (C2) may be an electronic control unit that controls the turning-on of the burners of the hob.
  • the detection means (S) are integrated in the second electronic control unit.
  • the second electronic control unit (C2) may be operatively connected to the first electronic control unit in wireless mode.
  • the deflector (50) is a plate hinged in a horizontal axis (A) in the center of the connection point (R) between the main duct (10) and the extraction branches (20, 21).
  • the length of the deflector (50) is higher than the internal diameter of the extraction branches (20, 30) and the width of the deflector (50) is substantially equal to the internal diameter of the extraction branches (20, 30).
  • the deflector (50) is hinged to the horizontal axis (A) along a central line of the deflector, in such a way to rotate around said horizontal axis (A).
  • the deflector (50) when the deflector (50) is in the first position, the deflector is disposed in horizontal direction along the axis of the horizontal portions of the extraction branches (20, 30). In such a way, the main duct (10) communicates with the two extraction branches (20, 30). Therefore, the extraction of the fan (40) is performed in correspondence of the two extraction branches (20, 30) when the detection means (S) inform the electronic control unit (C1) that the burners of the first portion (P1) and of the second portion (P2) of the hob are active.
  • the deflector (50) when the deflector (50) is in the second position, the deflector is inclined by approximately 20° - 30° relative to a horizontal plane, obstructing the air extraction in the second extraction branch (30) and enabling the air extraction only in the first extraction branch (20).
  • the deflector (50) is moved to the second position when the detection means (S) inform the electronic control unit (C1) that the burners of the second portion (P2) of the hob (P) are not active and only the burners of the first portion (P1) of the hob (P), which is served by the first extraction branch (20), are active.
  • the deflector (50) when the deflector (50) is in the third position, the deflector is inclined in an opposite direction relative to the one of Fig. 2 . In such a position, the deflector (50) obstructs the air extraction in the first extraction branch (20) and enables the air extraction only in the second extraction branch (30).
  • the deflector (50) is moved to the third position when the detection means (S) inform the electronic control unit (C1) that only the burners of the second portion (P2) of the hob (P) are active.
