Definitions

  • the present invention relates to cooking ovens for food, both for domestic and professional use, and in particular to an oven provided with shelves rotatable around a vertical journal and removable therefrom.
  • ovens are known to comprise a plurality of removable shelves which slide horizontally along guides arranged on the side walls.
  • guides may be made by shaping suitable rises on the sheet forming the side wall.
  • the guides may consist of a pair of horizontal bars joined by end vertical bars so as to form a separate frame mounted inside the oven cavity.
  • the shelves generally consist of pans or are grid-shaped, i.e. with a perimetral frame having welded thereon transversal bars, and they are completely removable from the oven, i.e. an end-stroke blocking device is not provided.
  • the access to the rear area of the shelf involves the introduction of the hands inside the heated oven and/or the use of very long kitchen utensils.
  • the object of the present invention is thus to provide a cooking oven overcoming the aforementioned pullbacks.
  • a first main advantage of the oven according to the present invention is the absolute safety in pulling out the shelves, which always remain perfectly horizontal and can not be inadvertently removed.
  • a second advantage is the easy access to any point of the shelf, without having to put one's hands into the oven, thanks to the possibility of completely pulling out the shelves.
  • a third advantage is the flexibility of use of said oven, allowing to use only rotatable shelves, or only the conventional slideable shelves, or a combination of rotatable and slideable shelves.
  • a further advantage of the rotatable shelves is the absolute freedom in the shape of the shelves and of the cross-section of the peripheral frame. In fact, since it is sufficient that the shelf is provided at one corner with the connection to the journal, the rest of the structure may be freely adapted to specific production requirements.
  • a cooking oven according to the present invention comprises a vertical journal 1 arranged in the front right comer of the oven (i.e. near the door) and secured between the bottom and the ceiling of the cooking space.
  • This journal 1 has coupled thereon a plurality of horizontal shelves 2, in particular four in the illustrated example, the uppermost shelf comprising a dripping-pan 3 integral with the frame instead of the conventional bars, the lowermost shelf being instead provided with lower hooks 4 so as to have inserted therein a removable dripping-pan 3', and the other two shelves being conventional grids.
  • Each shelf 2 is coupled to journal 1 through an identical connection 5, described in detail further on, and in a plan view ( Figure 2) has a shape matching with the necessary clearance the rectangular plan of the oven except for comer 6 opposite to connection 5.
  • said corner 6 must be rounded so that no point of shelf 2 lies at a distance from the rotation axis greater than the distance between said axis and the side wall opposite thereto, the left one in this case.
  • shelf 2 may be rotated through 90° in a pulled-out position, as shown in dotted lines in Figure 2.
  • a further advantage of this type of shelf is its very silent extraction, unlike the conventional metal grids which frictionally slide over metal guides.
  • connection 5 will be hereinafter described in detail with reference to Figure 3.
  • This figure clearly shows that connection 5 consists of a cylindrical body 7 with a C-shaped cross-section, having an inner diameter equal to the outer diameter of journal 1 (obviously with the adequate tolerances).
  • the cross-sectional view along line A-A shows that said body 7 has, in the lower portion, a radial projection 8 along the inner perimeter which reduces the inner diameter thereof for a determined length.
  • Body 7 further has, at its upper end, a pair of opposite lugs 9, which cause the same diameter reduction of projection 8 but extend only along the mouth of the C-shaped section, i.e. outwardly with respect to the inner diameter along which projection 8 extends.
  • Figure 4 shows how each shelf 2 may be rotated or removed independently of the other shelves.
  • journal I At the height where each shelf 2 has to be coupled, journal I has an upper sinking groove 10 and a lower sinking groove 11 having a diameter equal to the inner diameter of projection 8. The distance between the lower abutment of groove 10 and the upper abutment of groove 11 is greater than the distance between projection 8 and lugs 9, and the height of grooves 10 and 11 is greater than the height of projection 8 and lugs 9, respectively.
  • connection 5 can be inserted on journal 1 at the level of such grooves 10 and 11 (view on the left).
  • connection 5 is free to rotate around journal 1 but can not be removed therefrom thanks to lugs 9 lying at the level of the outer diameter of journal 1 and no longer at the level of groove 10.
  • the shelf uncoupling is obviously performed by a movement opposite to the coupling.
  • Journal 1 may obviously be arranged either on the left or the right and it is preferably removably coupled in the cooking space by any known device, e.g. through a bayonet connection.
  • the removability of journal 1 besides making the oven cleaning easier, allows to use the conventional slideable shelves instead of the rotatable ones, by inserting them in the usual side guides which for simplicity's sake are not represented in Figures 1 and 2.
  • journal 1 may be provided shorter than the height of the cooking space and coupled only to the bottom or the ceiling. It is thus possible to combine one or more slideable shelves with one or more rotatable shelves. It is also possible to combine two removable journals 1 having an overall length not greater than the height of the cooking space, e.g. a first journal on the bottom right and a second journal on the ceiling left. Thus some shelves will be pulled out leftwards and the others rightwards, and furthermore it is possible to choose whether to keep the rotatable shelves above and the slideable ones below or vice versa, depending upon the removed journal.
  • each shelf 2 is coupled to a respective journal 1' secured to a side wall, instead of having a journal 1 coupled to the bottom and/or to the ceiling of the cooking space and carrying a plurality of shelves 2.
  • Connections 5' as well are slightly different from the connections 5 illustrated above, as it is clear from the plan and cross-sectional views of Figure 6.
  • the cross-sectional view along line B-B shows that the lower portion of cylindrical body 7 is left substantially unchanged, with the radial projection 8, whereas lugs 9 of connection 5 are joined together so as to form an upper ring 9' having an inner diameter equal to the diameter of projection 8.
  • Other different details are the orientation of the mouth of body 7, rotated 90° clockwise with respect to Figure 3, and the shape of the coupling flange of connection 5' on shelf 2. It should be noted that such modifications are intended only to illustrate possible different embodiments, since connections 5 of the first embodiment could be used also in this case with single short journals 1'.
  • connection 5' to journal 1' is quite similar to the coupling of connection 5 of Figure 4.
  • Each journal 1' has a sinking upper section 10' and a lower groove 11, both having a diameter equal to the inner diameter of projection 8 (with the adequate tolerances).
  • the distance between the top of section 10' (i.e. of journal 1') and the upper abutment of groove 11 is greater than the distance between projection 8 and ring 9', and the height of groove 11 is greater than the height of projection 8.
  • the height of lower groove 11 is such that, when projection 8 abuts on the lower abutment of said groove, the lower end of ring 9' abuts on the abutment of the sinking section 10' (lower view). In such a position, kept by shelf 2 due to the gravity, connection 5' is free to rotate around journal 1' but can not be removed therefrom thanks to ring 9' inserted on section 10'.
  • the shelf uncoupling is obviously performed by a movement opposite to the coupling.
  • each journal 1' may be selectively removed from the oven in order to use in the same position a conventional slideable shelf to be inserted in corresponding guides 13 arranged behind journals 1' ( Figure 5).
  • journal 1' on the right side wall and others on the left wall, so as to have some shelves rotating clockwise and others counter-clockwise. It is also possible to combine one or more single journals 1' with a "multiple" journal 1 carrying a plurality of shelves 2.
  • Figures 8 and 9 illustrate a third embodiment which differs from the previous one for the arrangement and the securing method of journals 1' in the cooking space.
  • journals 1' are secured on a vertical elongated plate 14 having a hole 15 at mid-height.
  • Said plate 14 has further coupled thereon the front ends of guides 13, each being formed by a pair of parallel horizontal bars which have their rear ends joined by a vertical bar 16.
  • Each journal 1' is secured on plate 14 so as to lie within the height "d" between the upper abutment of a guide 13 and the lower abutment of the overlying guide 13.
  • hole 15 and bottom and top bars 13a of guides 13 are used.
  • the rear ends of said bars 13a extend beyond the vertical bar 16 and are introduced into suitable holes provided into the rear wall 17 of the cooking space.
  • the fastening of the member in such a position is performed by a bolt 12' (in dotted lines), which is introduced into hole 15 and blocks plate 14 through a ring nut.
  • This mounting solution has the advantage of allowing the application of the rotatable shelves as post-sale accessories on ovens already in use. In fact, it is sufficient to replace the conventional guide-carrier plate by this guide-carrier plate 14 provided also with journals 1'.
  • journal 1' allows to keep in the oven at the same time all the rotatable and slideable shelves, since they do not interfere with one another.
  • each journal 1' being screwed on a respective bolt 12 arranged at a suitable height for preventing interferences with guides 13.
  • shelves 2 may be freely changed in their structure, number and shape, the latter anyhow complying with the aforementioned rotation constraint.
  • connections 5, 5' and the relating journals 1, 1' may be otherwise produced as long as they allow the independent rotation and removal of each shelf.
  • shelves 2 may be provided with connections 5, 5' made so as to allow the use of shelves 2 both as slideable shelves on guides 13 and as rotatable shelves on journals 1, 1'.
