Description The present invention relates to an oven cavity for a cooking oven according to the preamble of claim 1. Further, the present invention relates to a method for assembling a protection box for a bottom heating element to a bottom wall of an oven cavity for a cooking oven. Additionally, the present invention relates to a corresponding cooking oven.
A typical oven cavity for a cooking oven includes a bottom heating element arranged below a bottom wall of said oven cavity. The bottom heating element is usually enclosed by a protection box. The protection box is attached at a bottom side of the oven cavity, so that the bottom heating element is arranged between the bottom wall of the oven cavity and the protection box.
The protection box is screwed or welded at a flange of the oven cavity. Said flange encloses completely or partially a front opening of the oven cavity. Further, the protection box may be snapped in place at the flange of the oven cavity, wherein subsequently laps are bended over. These methods for mounting the protection box at the flange are very laborious.
Thus, it is an object of the present invention to provide an improved oven cavity with a protection box for the bottom heating element, wherein the protection box may be connected to the bottom side of the oven cavity by a simple way.
The object of the present invention is achieved by the oven cavity according to claim 1.
According to the present invention a front portion of the protection box is inserted in or insertable into the cavity flange and a rear portion of the protection box comprises at least one fastening element connected or connectable to a rear wall and/or a bottom wall of the oven cavity.
The core of the present invention is that at first the front portion of the protection box is inserted into the cavity flange and the rear portion of said protection box is connected by the at least one fastening element to the rear and/or bottom wall of the oven cavity. This concept allows a very simple assembling of the protection box at the oven cavity. A use of screws or a welding is not required for the assembling of the protection box at the oven cavity. The present invention allows that the protection box can be made of metal sheet with a thickness of less than 0.4 mm.
Preferably, the cavity flange has a U-shaped profile, wherein an open side of said U-shaped profile is directed to a rear side of the oven cavity. The U- shaped profile supports the insertion of the front portion of the protection box into the cavity flange.
Further, a flange section may be formed at the front portion of the protection box, wherein said flange section is inserted in or insertable into the cavity flange of the oven cavity.
In particular, at least one resilient deformable appendix is formed at the front portion of the protection box, wherein said resilient deformable element is inserted in or insertable into the cavity flange. This allows an additional fastening of the protection box.
For example, at least one resilient deformable appendix is tongue-shaped and directed forward. Alternatively or additionally, at least one resilient deformable appendix has the form of a ring section.
Preferably, at least one tongue-shaped appendix is enclosed by the appendix with the form of the ring section. The tongue-shaped appendix and the appendix with the form of the ring section may extend within different planes. Further, at least one angled appendix may be arranged at the front portion of the protection box, wherein said angled appendix is engageable with at least one corresponding element of the cavity flange and/or the oven cavity.
In particular, two angled appendices correspond with a T-shaped appendix at the cavity flange. Said T-shaped appendix and the angled appendices prevent that the protection box moves backwards.
According to a preferred embodiment of the present invention, the rear portion of the protection box comprises at least one lug element connected or connectable to a corresponding slot at the rear wall and/or at the bottom wall of the oven cavity.
For example, the slot may be formed in a lamellar bar arranged at the rear wall and/or at the bottom wall of the oven cavity.
Preferably, the lug element comprises at least one barbed hook.
Further, the present invention relates to a method for assembling a protection box for a bottom heating element to a bottom wall of an oven cavity for a cooking oven, which method comprises the steps of:
- inserting a front portion of the protection box into a cavity flange of the oven cavity, and
- connecting at least one fastening element at a rear portion of the
protection box to a rear wall and/or a bottom wall of the oven cavity.
Preferably, the method is provided for an oven cavity described above. At last, the present invention relates to a cooking oven with at least one oven cavity, wherein the cooking oven comprises at least one oven cavity described above. Novel and inventive features of the present invention are set forth in the appended claims.

FIG 1 illustrates a perspective view of an oven cavity for a cooking oven according to a preferred embodiment of the present invention,
FIG 2 illustrates a perspective view of the oven cavity with a protection box at a bottom side of the oven cavity according to the preferred embodiment of the present invention,
FIG 3 illustrates a perspective view of the oven cavity with the
protection box in a semi-mounted state according to the preferred embodiment of the present invention, illustrates a detailed perspective view of a front portion of the protection box in an unmounted state at the oven cavity according to the preferred embodiment of the present invention, illustrates a detailed perspective view of the front portion of the protection box in a semi-mounted state at the oven cavity according to the preferred embodiment of the present invention, and illustrates a more detailed perspective view of the front portion of the protection box in a mounted state at the oven cavity according to the preferred embodiment of the present invention. FIG 1 illustrates a perspective view of an oven cavity 10 for a cooking oven according to a preferred embodiment of the present invention. FIG 1 shows the oven cavity 10 from its rear side. The oven cavity 10 includes a top wall 16, a rear wall 18, two side walls 20, a bottom wall 22 and a front opening. The front opening is enclosed by a cavity flange 14. In this example, the cavity flange 14 has a U-shaped profile, wherein the open side of said U-shaped profile is directed to the rear side of the oven cavity 10.
A protection box 12 is attached below the bottom wall 22. The protection box 12 encloses partially a bottom heating element arranged below the bottom wall 22. Thus, the bottom heating element is arranged between the bottom wall 22 and the protection box 12.
FIG 2 illustrates a perspective view of the oven cavity 10 with the protection box 12 at the bottom wall 22 of the oven cavity 10 according to the preferred embodiment of the present invention. FIG 2 clarifies the arrangement of the protection box 12 at the bottom wall 22.
The protection box 12 comprises a flange section 24 extending along the front side of said protection box 12. The flange section 24 is inserted in a lower part of the cavity flange 14. Thus, the front portion of the protection box 12 is hanging in said lower part of the cavity flange 14.
Further, the protection box 12 comprises two curved lug elements 26. The lug elements 26 are inserted in two corresponding slots 28 at the rear wall 18 of the oven cavity 10. The slots 28 are formed in a lamellar bar 30 at the rear wall 18, wherein the plane of said lamellar bar 30 extends
perpendicular to the plane of the rear wall 18. In this example, the lug elements 26 comprise two lateral barbed hooks 32 in each case. Thus, the lug element 26 with the both barbed hooks 32 and the corresponding slot 28 form a snap-in mechanism. The protection box 12 is attached at the bottom wall 22 by inserting the flange section 24 into the lower part of the cavity flange 14 and subsequent inserting the lug elements 26 into the corresponding slots 28. FIG 3 illustrates a perspective view of the oven cavity 10 with the protection box 12 in a semi-mounted state according to the preferred embodiment of the present invention. In this situation, the flange section 24 of the protection box 12 is inserted in the lower part of the cavity flange 14, while the lug elements 26 are not yet inserted into the corresponding slots 28.
FIG 3 clarifies that the flange section 24 of the protection box is inserted into the lower part of the cavity flange 14 in a first step, and the lug elements 26 are inserted into the corresponding slots 28 in a second step. FIG 4 illustrates a detailed perspective view of a front portion of the protection box 12 in an unmounted state at the oven cavity 10 according to the preferred embodiment of the present invention. In FIG 4 the oven cavity 10 with the protection box 12 is shown upside-down. The protection box 12 comprises the flange section 24. In this example, the flange section 24 comprises two inner appendices 34. Each inner appendix 34 is enclosed by a corresponding outer appendix 36. The inner appendices 34 and the outer appendices 36 extend forward. The inner appendices 34 are tongue-shaped. The outer appendices 36 are U-shaped or have the form of a circular ring section.
The inner appendices 34 and the outer appendices 36 are provided for inserting into the cavity flange 14. After inserting into the cavity flange 14 the inner 34 and outer 36 appendices are resiliently deformed, so that they snap into place within the cavity flange 14.
Further, a T-shaped appendix 38 is provided in the centre of the lower part of the cavity flange 14. The T-shaped appendix 38 is directed rearward. In a similar way, two angled appendices 40 are arranged in the centre of the flange section 24. The angled appendices 40 are directed upward in FIG 4, and directed downward in reality. The distance between said angled appendices 40 corresponds with the T-shaped appendix 38, so that the T- shaped appendix 38 of the cavity flange 14 engages with both angled appendices 40 of the flange section 24, when said flange section 24 is inserted in the cavity flange 14.
FIG 5 illustrates a detailed perspective view of the front portion of the protection box 12 in a semi-mounted state at the oven cavity 10 according to the preferred embodiment of the present invention. The flange section 24 of the protection box 12 is partially inserted in the cavity flange 14.
The inner appendices 34, the outer appendices 36 and the angled
appendices 40 of the flange section 24 are hidden by the cavity flange 14. During the insertion the protection box 12 is inclined.
FIG 6 illustrates a more detailed perspective view of the front portion of the protection box 12 in a mounted state at the oven cavity 10 according to the preferred embodiment of the present invention. FIG 6 shows the T-shaped appendix 38 of the cavity flange 14 engaged between the angled appendices 40. The T-shaped appendix 38 and the angled appendices 40 prevent that the protection box 12 moves backwards. The oven cavity 10 according to the present invention allows a very simple assembling of the protection box 12 at the oven cavity 10. A use of screws or a welding is not required for the assembling of the protection box 12 at the oven cavity 10.
The protection box 12 can be made of metal sheet with a thickness of less than 0.4 mm. The protection box 12 described above is provided for the bottom heating element. Further, the protection box 12 may be also provided for a top heating element and/or further heating elements of the oven cavity 10. Although an illustrative embodiment of the present invention has been described herein with reference to the accompanying drawings, it is to be understood that the present invention is not limited to that precise embodiment, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the invention.
