Abstract

The present invention relates to fixing a lattice carrier rail in a household appliance, in particular in an oven, comprising a furnace space defined by a top wall, a lower wall and side walls and is closed at the first end with a back wall, and at the opposite end it can be closing from the door, with a respective lattice carrier arranged at each side wall, which can be fixedly fixed at the side walls of the oven space. According to the present invention it is provided that a series of screws (8) is attached to the back wall (7), which holds the fan cover (9) positively. In addition, an additional screw (8) and the latter fastening screw (15) are attached to each side wall (5, 6), said screws (8, 15) being positively fixed to the respective lattice support rail (5.1, 6.1) at each side a wall (5, 6) in the oven space (2).

Attach the grid guide bracket to the oven

The present invention relates to the attachment of a lattice carrier bracket in a household appliance, in particular in an oven, comprising an oven space defined by an upper wall, a lower wall and side walls and closed at the first end by a back wall, and at the opposite end thereof. closed with a door, with a lattice bracket arranged on each side wall, which can be positionally fixed to the side walls of the oven space.

For example, the attachment of the lattice guide carrier of the above mentioned type is known from patent document DE 199420705 Ul. In this document, the method of attachment disclosed is only applicable to stainless steel ovens, whereas in the case of an enamel oven, such an attachment method is not applicable. The problem is when installing and removing the grilles, as the enamel can crack, especially in the area of the receiving hole if the grille accidentally hits the edge of the hole.

It is an object of the present invention to provide a novel method of fixing a lattice carrier to a guide in a household appliance, especially in an oven, which eliminates the disadvantages of known solutions.

The task according to the invention is solved by the characteristics given in the characteristic part of claim 1. Details of the invention are disclosed in the corresponding sub-claims.

The invention will now be described in more detail with reference to an embodiment and with reference to the accompanying drawings, in which FIG. 1 is a schematic three-dimensional view of the oven; 2 positioning bolt for the three-dimensional view of the lattice carrier bracket.

The household appliance, in particular the oven 1, comprises an oven space 2 which is circumferentially circumscribed by the upper wall 3, the lower wall 4 and the side walls 5, 6, and which is bounded at the first end of the circumference by the back wall 7 and at the opposite end by not shown return. All walls 3, 4, 5, 6, 7 are preferably coated with an enamel protective layer. On each side wall 5, 6, there is a single grid support 5.1, 6.1 for receiving a baking apparatus, for example. A fan cover 9 is attached to said back wall 7 by means of a series of screws 8. Each of said screws 8 is arranged in each vertical edge region of said back wall 7, and according to a preferred and illustrated embodiment, one pair of said screws 8 is provided in said respective vertical edge region. Further, each said screw 8 is fixed on the back of said back wall 7 by means of a non-shown nut, with a sealing washer optionally arranged between the nut and the back of the back wall 7. Said sealing washer can optionally be arranged between the back wall 7 and the fan cover 9, thus preventing the enamel elements from interacting with each other.

Each of said screws 8 is designed with a radially intense head 10 from which the threaded stem 11 is derived, wherein said screw 8 on the side of said head 10 is designed with a threaded hole 12 concentrically with respect to the threaded stem 11. that the diameter of said threaded hole 12 is smaller than the diameter of said threaded stem 11. Further, according to the present invention, it is provided that said threaded hole 12 is a blind threaded hole, but an embodiment is also possible in which said threaded hole 12 is through a threaded hole.

In each case, said grating carrier 5.1, 6.1 is guided into the oven space 2 by essentially inserting a horizontal extension 13, 14 of the grating carrier 5.1, 6.1 into said threaded hole 12 of each said screw 8. For example, cooperation between said hole 12 and said extension 13, 14 provides a loose match between the latter. In order to secure the positioning grating bracket 5.1, 6.1 in each case and secure it against unintentional failure from said holes 12 of screw 8, the said grating bracket 5.1, 6.1 is further secured by means of a retaining screw 15 screwed into the threaded hole of an additional screw fastened into the respective side wall 5, 6. In the present invention, it is preferably provided that said additional screw is identical to said screw 8.

The mounting of the grid support 5.1, 6.1 guides as described above is practically applicable to all types of ovens, such as steam, pyrolytic, multifunction, microwave and the like. In this way, said grid supports 5.1, 6.1 guides and said screws 8 are the same for all types of ovens, thereby significantly reducing production costs and speeding up the assembly of the ovens. In addition, there is no need for different fan rims and covers as they are identical for all types of ovens listed.
