Description

Technical Field

[0001] This invention relates to a household appliance, specifically to a household oven whose surface is protected by enamel, the household oven comprising a body, an upper heating element and a lower heating element, the body having a door opening, the upper heating element being disposed in the top wall region and inside the body, and the lower heating element being disposed in the bottom wall region and outside the body. Background Technology

[0002] Known household ovens include a lower heating element that is screwed to the oven body on at least one side, or screwed to a separate predetermined carrier, or screwed to a carrier that is an integral part of the oven.

[0003] In addition, there are solutions that include a predetermined sheet metal, which is an integral part of the oven (e.g., welded to the main body), or a predetermined separate element, both for positioning and securing the lower heating element. Similar solutions involve a cover for the lower heating element, which is mounted as a separate component on the insulation of the oven, welded to the main body of the oven, or fastened to the oven.

[0004] The clamping and positioning of the lower heating element are important factors because they affect the final heat treatment result of the food in the oven. Furthermore, the distance between the lower heating element and the bottom wall of the oven body is also crucial, as contact between the lower heating element and the bottom wall can cause overheating, leading to cracking of the enamel at the contact point. On the other hand, the lower heating element must not be placed directly on insulating material, as overheating of the lower heating element can cause the insulation to fail. Summary of the Invention

[0005] The purpose of this invention is to create a household oven with a novel arrangement of the lower heating element.

[0006] The objective of this invention is achieved through the features described in the embodiments. Details of this invention are also disclosed in the embodiments. Attached Figure Description

[0007] The invention is presented in more detail below with reference to non-limiting embodiments and the accompanying drawings, wherein...

[0009] Figure 2 It is the lower heating element and protective cover unit.

[0010] Figure 3 yes Figure 1 Detail A. Detailed Implementation

[0011] The household oven according to the invention includes a main body composed of a top wall 1, a bottom wall 2, side walls 3 and 4, a rear wall 5, and a front wall 6. The top wall, bottom wall, side walls, rear wall, and front wall define an oven space 7, which can be closed by a door (not shown) intended to be located in the front wall 6. In the region of the top wall 1, an upper heating element (not shown) is arranged inside the oven space 7, while a lower heating element 8 is arranged in the region of the bottom wall 2 and located outside the oven space 7. The lower heating element is protected by a flat cover 9 (in...) of the lower heating element 8. Figure 1 (shown in dashed line) to protect against direct contact with the heat insulation material (not shown) of the household oven.

[0012] Furthermore, in the bottom wall 2 of the household oven according to the invention, a carrier 10, preferably welded to the bottom wall 2, is attached to the area of ​​the rear wall 5 and located on one side of the cover 9 facing the downward heating element 8. The carrier 10, extending approximately parallel to the bottom wall 2, is also intended to temporarily secure the household oven body during transport in the enamel process.

[0013] The lower heating element 8 is equipped with at least two wire mounts 11', 11" which extend in the plane of the cover 9 from the rear wall 5 toward the front wall 6 and are detachably connected to the cover 9 via a series of through holes 12 formed in the cover 9. The mounts 11', 11" are also connected (e.g., welded) to the lower heating element 8 by a set of fasteners 13. A flange 14 is provided on the side of the lower heating element 8 facing the rear wall 5 and longitudinally spaced from the cover 9, the flange maintaining a constant distance between the free ends of the lower heating element 8. The flange 14 is designed to engage with the carrier 10 in a form-locking and / or force-locking manner, for example, through a tongue and groove joint. Furthermore, the flange 14 is optionally protected to prevent release of the form-locking and / or force-locking engagement. The aforementioned protection is selected to be without removable connecting elements, such as snap-fit ​​engagements, subsequent deformation of a portion of the carrier 10, and / or the flange 14.

[0014] The lower heating element 8, which is permanently connected to the linear brackets 11', 11"; the flange 14, which is permanently connected to the lower heating element 8; and the cover 9, which is detachably connected to the linear brackets 11', 11" of the lower heating element 8, represent a uniform unit 15 that can be attached to the bottom wall 2 of a household oven.

[0015] The lower heating element 8 is detachably connected to the carrier 10 via a flange 14 extending approximately perpendicular to the carrier 10. This detachable connection is provided as a form-locking connection and / or a force-locking connection. The flange 14 is intended to serve as a first support point for holding the lower heating element 8 or the unified unit 15 in a suitable position; therefore, the flange 14 is designed with one or more through-holes for passage of the lower heating element 8.

[0016] The second support point for keeping the lower heating element 8 or the unified unit 15 in a suitable position is the free end of the linear support 11', 11" facing the front wall 6 of the household oven. The free end of the linear support 11', 11" rests on the front wall 6 on one hand on the approximately horizontal first bend 6' extending toward the rear wall 5, and on the other hand is accommodated in a corresponding notch 16 formed in the second bend 2' of the bottom wall 2, which extends parallel to the first bend 6' of the front wall and at a certain distance from the first bend of the front wall.

[0017] Furthermore, the linear supports 11', 11" are designed in each case to have at least one corrugated portion 17 in their longitudinal direction, the corrugated portion facing the bottom wall 2 and / or the cover 9. According to the present invention, it is envisioned that the corrugated portion 17 rests against the bottom wall 2 and / or against the cover 9, thereby ensuring that the distance from the cover 9 to the lower heating element 8 or the distance from the heating element 8 to the bottom wall 2 of the oven is constant.
