Description
The present invention relates to a household appliance, in particular to a household oven, the surface of which is protected by enamel (enamal), comprising a main body having a door opening, an upper heating element arranged in a top wall area and the interior of the main body, and a lower heating element arranged in a bottom wall area and the exterior of the main body.
Known household ovens comprise a lower heating element screwed on at least one side to the oven body, either to a separate predetermined carrier, or to a carrier that is an 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.
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 characterizing portion of claim 1. The details of the invention are disclosed in the corresponding dependent claims.
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.
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 support 11', 11" represent a unified unit (unite) 15 that can be attached to the bottom wall 2 of a domestic oven.
The lower heating element 8 is detachably connected to the carrier 10 by means of a flange 14 which extends approximately perpendicular to the carrier 10. The releasable engagement is provided as a form locking engagement and/or a force locking engagement. The flange 14 is intended as a first support point for holding the lower heating element 8 or the unit 15 in place, whereby the flange 14 is designed with one or more through holes for the passage of the lower heating element 8.
The second support point for the lower heating element 8 or the unit 15 to remain in place is the free end of the wire-like brackets 11', 11", which faces the front wall 6 of the domestic oven. The free ends of the wire-like brackets 11', 11″ rest on the one hand on an approximately horizontal curvature 6' of the front wall 6 extending towards the rear wall 5 and on the other hand are accommodated in corresponding notches 16 formed in a curvature 2 'of the bottom wall 2, which curvature extends parallel to and at a distance from the curvature 6' of the front wall.
Furthermore, the wire-like holders 11', 11″ are designed in each case (in each case) with at least one wavy portion 17 in their longitudinal direction, which wavy portion faces the bottom wall 2 and/or the hood 9. According to the present invention, it is envisaged that the undulating portion 17 rests on the bottom wall 2 and/or on the shield 9, thereby ensuring a constant distance of the shield 9 to the lower heating element 8 or of the heating element 8 to the bottom wall 2 of the oven.
