  5. 5. A household oven according to claim 2, characterized in that the lower heating element (8) or the unified unit (15) is held in place by a free end of the wire-like support (11 ', 11 ") facing the front wall (6) of the household oven, which free end of the wire-like support (11', 11") rests on the one hand on the approximately horizontal first curved portion (6 ') of the front wall (6) extending towards the rear wall (5) and on the other hand is accommodated in a corresponding notch (16) formed in a second curved portion (2') of the bottom wall (2), wherein the second curved portion (2 ') extends parallel to and at a distance from the first curved portion (6') of the front wall.

Description

Household oven comprising an arrangement of lower heating elements Technical Field The present invention relates to a household appliance, in particular to a household oven, the surface of which is protected by enamel (enamel), comprising a main body with a door opening, an upper heating element arranged in a top wall region and the interior of the main body, and a lower heating element arranged in a bottom wall region and the exterior of the main body. Background Known household ovens comprise a lower heating element screwed to the oven body on at least one side, either to a separate predetermined carrier, or to a carrier as an integral part (INTEGRAL PART) of the oven. In addition, there are solutions comprising a predetermined metal plate (INTENDED SHEET METAL) which is an integral part of the oven (for example welded to the main body), or which is a predetermined separate element, both provided for positioning and fixing the lower heating element. A similar solution relates to a shield for the lower heating element, which shield is placed as a separate part on the insulating material (insulation) of the domestic oven, or welded to the body of the domestic oven, or fastened to the oven. The grip and position of the lower heating elements are important factors as they affect the final heat treatment result of the food in the oven. Furthermore, the distance of the lower heating element from the bottom wall of the oven body is also important, as contact of the lower heating element with the bottom wall of the oven body may cause overheating of the bottom wall, thereby breaking the enamel at the contact point. On the other hand, the lower heating element must not be placed directly on the insulating material, as overheating of the lower heating element may result in failure of the insulating material. Disclosure of Invention The object of the present invention is to create a household oven with a novel arrangement of lower heating elements. The object of the invention is achieved by the features set forth in the examples. Details of the invention are also disclosed in the embodiments of the invention. Drawings The invention will be presented in more detail below, based on non-limiting embodiments and with reference to the attached drawings, wherein, Figure 1 shows a household oven according to the invention in a three-dimensional view from below and upwards, Figure 2 is a lower heating element and shield unit, Fig. 3 is detail a of fig. 1. Detailed Description The household oven according to the invention comprises a main body consisting of a top wall 1, a bottom wall 2, side walls 3,4, a rear wall 5 and a front wall 6, which 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 outside the oven space 7. The lower heating element is protected from direct contact with the heat insulating material (not shown) of the household oven by a flat shield 9 (shown in phantom in fig. 1) of the lower heating element 8. Furthermore, on the bottom wall 2 of the household oven according to the invention, a carrier 10, preferably welded to the bottom wall 2, is attached in the area of the rear wall 5 and on the side of the hood 9 facing the downward heating element 8. The carrier 10 extending approximately parallel to the bottom wall 2 is also intended to temporarily fasten the household oven body during transport of the household oven body in an enamelling process. The lower heating element 8 is provided with at least two wire mounts (11', 11 ") extending in the plane of the shield 9 in a direction from the rear wall 5 towards the front wall 6 and being detachably connected to the shield 9 by means of a series of through holes 12 formed in the shield 9. The brackets 11', 11 "are also connected (e.g. welded) to the lower heating element 8 by a set of fasteners 13. On the side of the lower heating element 8 facing the rear wall 5 and at a longitudinal distance from the hood 9, a flange 14 is provided, which keeps the free ends of the lower heating element 8 at a constant distance from each other. The flange 14 is designed to be in form-locking engagement and/or force-locking engagement with the carrier 10, for example, by tongue and groove engagement. Furthermore, the flange 14 is optionally protected from release of the form-locking engagement and/or force-locking engagement. The protection is selected to be free of removable connection elements, e.g. by snap engagement, subsequent deformation of a part of the carrier 10 and/or the flange 14, etc. The lower heating element 8 permanently connected to the wire-like support 11', 11", the flange 14 permanently connected to the lower heating element 8 and the shield 9 of the lower heating element 8 detachably connected to the wire-like su
