Definitions

• the present invention relates to a suction device for domestic ovens for cooking food.
• the suction device of the known art solves the problem of sucking fumes, vapours and odours upon opening the domestic oven but is not entirely efficient.
• the object of the present invention is to manufacture a suction device for a domestic oven for cooking food which is capable of overcoming the drawbacks of the known art.
• a suction device for domestic ovens for cooking food is provided, the suction device being configured to be arranged above the door of a domestic oven and comprising:
• the fan arranged in the proximity of the suction mouth and the delivery mouth ensures greater suction efficacy.
• vapours and fumes are subjected to a settling process to abate possible solid particles suspended in the fumes and vapours.
• the drawer comprises two fans arranged from opposite bands of the delivery mouth.
• This configuration allows greater suction efficacy also thanks to the use of tangential fans.
• the manifold is divided into two chambers, each of which is in fluidic communication with the delivery mouth and a respective fan so as to favour the settling process of possible solid particles suspended in the fumes and vapours.
• the suction device provides for letting the suitably filtered fumes and vapours back into the environment and, in this manner, the structure of the suction device results to be simplified and does not require further interventions in the environment in which it is installed.
• the drawer comprises an activated carbon filter arranged at the suction mouth and thus upstream of the fan, and a photocatalytic filter at the delivery mouth downstream of the fan and the manifold. In this manner, possible greases do not dirty the fan and the manifold.
• the drawer is arranged to rest on the guides, thereby transmitting substantially vertical forces to the guides that do not create bending moments.
• the suction device comprises a magnetic end stop that cooperates with an element associated with the drawer to lock the drawer in an extracted position.
• This solution allows the drawer to be easily released by pushing, even after an impact with a user and prevents the impact from causing damage to the user.
• the suction device comprises a microswitch for selectively energizing and interrupting the power supply to the fan, the microswitch being arranged in a given position along the guides and actuated by the drawer.
• reference numeral 1 indicates a suction device recessed in a kitchen furnishing 2 and arranged above a domestic oven 3 for cooking food.
• the suction device comprises a support structure 4, in this case defined by a box-like body with a front opening, and a drawer 5 which is slidable inside the support structure 4 between a retracted position, illustrated in Figure 1 , and an extracted position, illustrated in Figure 2 .
• the support structure 4 is fixed to the kitchen furnishing 2 inside a compartment 6 and comprises two guides 7, only one of which is shown in Figure 2 , for slidably supporting the drawer 5 and a spring system 8 for ejecting the drawer 5 from the support structure 4.
• the suction device 1 has the function of sucking fumes, vapours and odours expelled from the domestic oven 3 following the opening of the domestic oven 3, filtering fumes, vapours and odours to retain suspended particles of grease or other and expelling the filtered fumes and vapours into the surrounding environment.
• the drawer 5 comprises a box-like body 9, to which a finishing panel 10 is applied frontally and comprises a lower wall 11 along which a suction mouth 12 is arranged, two side walls 13 coupled to the guides 7 ( Figure 4 ), an upper wall 14 along which a delivery mouth 15 is arranged, and a rear wall 16 ( Figure 2 ).
• the drawer 5 comprises two fans 17, which are housed inside the box-like body 9 between the suction mouth 12 and the delivery mouth 15.
• each fan 17 is arranged from opposite bands of the delivery mouth 15.
• Each fan 17 is a tangential fan and substantially has an elongated body arranged parallel to the side walls 13.
• the drawer 5 comprises an anti-grease and anti-odour filter, with activated carbon C, at the suction mouth 12 and a photocatalytic filter 22 for the reduction of environmental pollutants such as carbon monoxide, volatile organic compounds (VOC), formaldehyde, viruses and bacteria arranged at the delivery mouth 15.
• environmental pollutants such as carbon monoxide, volatile organic compounds (VOC), formaldehyde, viruses and bacteria arranged at the delivery mouth 15.
• the drawer 5 comprises grids 20 and 21 arranged at the delivery mouth 15 to support the photocatalytic filter 22, which in this case is a tungsten trioxide photocatalytic filter activated by LED lights, not illustrated in the accompanying figures.
• the photocatalytic filter 22 which in this case is a tungsten trioxide photocatalytic filter activated by LED lights, not illustrated in the accompanying figures.
• the side walls 13 of the drawer 5 are recessed at the lower wall 11 so as to allow the drawer 5 to be arranged to rest above the guides 7.
• the suction device 1 comprises a mechanical stop 23 arranged along at least one guide 7 and configured to interact with an element 24 integral with the drawer 5; a microswitch 25 configured to interact with the element 24 and selectively energize the fans 17 and a magnetic end stop 26 for locking the drawer 5 in a given position when extracted.
• the activation of the suction device 1 provides for pushing the panel against the action of the spring system 8 so as to release the drawer 5 from the mechanical stop 23.
• the mechanical stop 23 and the spring system 8 together define a push-pull mechanism.
• the drawer 5 is pushed into the retracted position.
• the drawer 5 activates the microswitch 25 again to deactivate the fans 17 until the drawer 5 is pushed against the spring system and the drawer 5 is stopped with the mechanical stop 23.
• the drawer comprises one single fan.
