Description
- The present invention relates to a vertical hood for the suction of cooking fumes having an openable cover panel. The hood according to the present invention finds valuable use in kitchens of domestic environments but also canteens, restaurants, and more.
- A vertical hood for the suction of cooking fumes is known in the state of the art. "Vertical hood" means a hood provided with a box-like body having a bottom wall arranged to be fixed to a wall, and having a frontal opening for the suction of fumes which is opposite with respect to the bottom wall. A filter for grease is positioned at the frontal opening.
- The hood comprises an openable panel connected to the box-like body placed to cover the frontal opening. In particular, in use, such a panel is closed on the frontal opening, i.e., it is interposed between the box-like body and the environment facing the hood so as to preclude access inside the box-like body. To access inside the box-like body, for example to clean and/or replace the filter, the panel can be opened by rotating it with respect to the box-like body by virtue of the presence of opening/closing means. In particular, when it is open, the panel is supported by a piston, connected to the panel and to the box-like body.
- To keep the panel closed, the hood includes the presence of magnetic elements or mechanical interlocking elements placed both on the box-like body and on the panel. In particular, the magnetic elements or the mechanical interlocking elements are coupled together and interact, keeping the panel against the box-like body when the panel is closed.
- Disadvantageously, the magnetic elements or the mechanical interlocking elements are damaged over time, partially or totally detaching from the hood body and/or from the panel. As a result, over time, the panel loses the ability to adhere to the box-like body, causing dust to enter the box-like body.
- In this context, the technical task underlying the present invention is to propose a hood for the suction of cooking fumes which overcomes the drawbacks of the above-mentioned prior art.
- In particular, it is an object of the present invention to provide a hood for the suction of cooking fumes having a panel which maintains the functionality thereof over time, and in which such a panel can be easily detached from the hood body by a user.
- It is a further object of the present invention to provide a hood for the suction of cooking fumes in which the mechanism which allows the movement of the panel is simple and inexpensive.
- The mentioned technical task and the specified objects are substantially achieved by a hood for the suction of cooking fumes comprising the technical features set out in one or more of the appended claims.
- In particular, the hood according to the present invention solves the technical problem in that it comprises opening/closing means placed between the panel and the box-like body which allow the panel to be rotated with respect to the box-like body. Such opening/closing means comprise a support element which is configured to keep the panel raised when it is open. In particular, such a support element is further arranged to push the panel against the box-like body when the panel is closed, so as to keep it adherent to the hood body.
- Therefore, the opening/closing means provide for both the movement of the panel and to keep the panel adherent to the box-like body when it is closed. As a result, the magnetic elements are not necessary.
- The features and advantages of the present invention will become apparent from the following detailed description of a possible practical embodiment thereof, illustrated by way of non-limiting example in the accompanying drawings, in which:

like body 2, or to remove thefilter 4 in order to clean or replace it, it is necessary to access thefrontal opening 3. In accordance, thepanel 5 is configured to switch between a closed configuration in which it precludes access inside the box-like body 2, and an open configuration in which the inside of the box-like body 2 is accessible through thefrontal opening 3. - The
panel 5 can be switched between one configuration and another by a user, by pulling or pushing thepanel 5. - The
hood 1 comprises opening/closing means 6 positioned between thepanel 5 and the box-like body 2 which allow the movement of thepanel 5. - The opening/closing means 6 allow the
panel 5 to be rotated with respect to the box-like body 2. Preferably, the rotation of thepanel 5 occurs along a rotation axis R which is substantially parallel to one side of thepanel 5, preferably at the upper side. - In particular, the opening/closing means 6 comprise a connecting
element 8 fixed to thepanel 5 and connected to the box-like body 2 to allow thepanel 5 to rotate with respect to the box-like body 2. - More in detail, the opening/closing means 6 further comprise a
support element 7 configured to keep thepanel 5 raised in the open configuration. Such asupport element 7 is connected to the connectingelement 8. - The
support element 7 is further arranged to push thepanel 5 against the box-like body 2 when thepanel 5 is in the closed configuration. In other words, thesupport element 7 is arranged to apply a force on thepanel 5 so as to keep it against the box-like body 2 when thepanel 5 is in the closed configuration. According to the embodiment which includes thespacer elements 54, thesupport element 7 is configured to keep thespacer elements 54 abutted against the box-like body 2 when thepanel 5 is in the closed configuration. - In accordance with the present invention, the opening/closing means 6 comprise a first

panel 5 is in the closed configuration, themovable hinge 11 is positioned above a line J joining the fixed hinges 9, 10. - In other words, when the
panel 5 is in the closed configuration, thesupport element 7 approaches thebottom wall 23 of the box-like body 2 with respect to the line J and is arranged to pull thepanel 5 closer to the box-like body 2. - When the
panel 5 is in the open configuration, themovable hinge 11 is positioned below a line J joining the fixed hinges 9, 10. - In other words, when the
panel 5 is in the open configuration, thesupport element 7 is close to thefrontal opening 3 of the box-like body 2 with respect to the line J and is arranged to push thepanel 5 away from the box-like body 2. - According to a preferred embodiment, the
panel 5 is further switchable in an intermediate configuration in which it is brought closer to the box-like body 2. In particular, the intermediate configuration is a passage configuration in which thepanel 5 is positioned to switch between the closed configuration and the open configuration and vice versa. - In the intermediate configuration, the
panel 5 is alongside thefrontal opening 3 but does not abut the box-like body 2. When thepanel 5 is in the intermediate configuration, themovable hinge 11 is aligned with the line J connecting the fixed hinges 9, 10. When thepanel 5 is in the intermediate configuration, the three hinges are aligned.

arm 13 further comprises a base 132 connected to thehead 131 in a central position. Thebase 132 is also symmetrical with respect to the central axis Y. In accordance, theentire arm 13 is substantially symmetrical with respect to the central axis Y. - Preferably, the
movable hinge 11 is placed at thebase 132. The connectingelement 8 is then connected to thesupport element 7 at thebase 132. It should be noted that, in accordance with such an embodiment, thehead 131 is opposite thesupport element 7 with respect to themovable hinge 11 in the closed configuration. More in detail, thehead 131 is opposite thepiston 12 with respect to themovable hinge 11 in the closed configuration. - Still in accordance with the preferred embodiment, the
head 131 has a first protrudingportion 133. Thehead 131 further has a secondintermediate portion 134. The first protrudingportion 133 and the secondintermediate portion 134 are opposite each other with respect to the central axis Y. In particular, the first protrudingportion 133 is opposite the firstfixed hinge 9 while the secondintermediate portion 134 faces the firstfixed hinge 9. - More specifically, the first protruding
portion 133 is configured to move closer to or away from thesupport element 7. In particular, when thearm 13 rotates with respect to thefirst hinge 9, the first protrudingportion 133 moves with respect to thepiston 12. In particular, the first protrudingportion 133 moves closer with respect to thesecond end 122 when thepanel 5 switches to the open configuration. The first protrudingportion 133 moves away from thesecond end 122 when thepanel 5 switches to the closed configuration. - In particular, preferably the
head 131 is arranged above the line J in the closed configuration. On the other hand, preferably thehead 131 is arranged substantially below the line J in the open configuration. Still preferably, thehead 131 is arranged above the line J in the intermediate configuration. - The rotation of the
arm 13 with respect to thefirst hinge 9 in turn moves thepiston 12 by means of themovable hinge 11. - In more detail, when the
panel 5 is in the closed configuration and a user pulls it to open it, thepiston 12 aligns with the line J in the intermediate configuration and it therefore moves below the line J towards thefrontal opening 3. When themovable hinge 11 is positioned below the line J, thepiston 12 applies a thrust force on thepanel 5. In other words, thepiston 12, together with thearm 13, exerts a force which keeps thepanel 5 away from the box-like body 2. Thepanel 5 is therefore in the open configuration. - When the
panel 5 is in the open configuration and a user pushes it to close it, thepiston 12 aligns with the line J in the intermediate configuration and thus moves above the line J towards thebottom wall 24. When themovable hinge 11 is positioned above the line J, thepiston 12 pulls thepanel 5. In other words, thepiston 12, together with thearm 13, exerts a force which keeps thepanel 5 close to the box-like body 2. More in particular, thepiston 12 exerts a force which keeps thepanel 5 against the box-like body 2. Thepanel 5 is therefore in the closed configuration. - The
piston 12 then pushes thepanel 5 against the box-like body 2 in the closed configuration or keeps it away from the box-like body 2 when thepanel 5 is in the open configuration. - The connecting
element 8 further comprises aguide 14, interposed between the firstfixed hinge 9 and thearm 13. Such aguide 14 preferably extends away from thehead 131. Preferably, theguide 14 extends along a curved direction. In accordance, theguide 14 has a shape, for example semicircular. - The box-
like body 2 comprises apin 15 at theguide 14 and inserted into theguide 14. - The
guide 14 is configured to slide with respect to thepin 15. In particular, theguide 14 slides with respect to thepin 15 when thepanel 5 switches between said configurations. - Even more preferably, beyond the
arm 13 and theguide 14, the connectingelement 8 comprises aspacer portion 81, connecting thearm 13 and theguide 14. Thespacer portion 81 extends from the firstfixed hinge 9 along the main extension direction X. Thearm 13 and theguide 14 depart from thespacer portion 81. More in detail, the secondintermediate portion 134 of thehead 131 is contiguous to thespacer portion 81. In other words, thehead 131 extends seamlessly with respect to thespacer portion 81, at the secondintermediate portion 134. Theguide 14 also extends seamlessly from thespacer portion 81. With respect to the main extension direction X, theguide 14 extends from the same part of thebase 132.
