Description

FIELD OF THE INVENTION

The invention relates to the field of mechanical engineering, in particular to electromechanical household electrical appliances, and can be used in a system for connecting components of a stove.

State of the art

Currently, fixing the components of the stove during its assembly is carried out using fasteners, such as screws or rivets and additional fittings, as shown in Fig.7. An assembly system using the set of parts that are included in the equipment kit increases the cost of the finished product, taking into account the costs not only of screws, clamps and other parts used for this purpose, but also taking into account the time and labor required to complete the assembly.

For example, the hob of the stove to the side parts is fastened with four screws or rivets, as shown in FIG. 7A, using additional connecting parts. All these operations, usually performed manually, take a lot of time, since it is necessary to ensure sufficient accuracy of the assembly.

In another operation of connecting the hob with the front plate, the hob is attached to the walls of the chamber, and its front part is blocked only by the plate, which is screwed to the camera body. The disadvantages of such a connection system are that the hob is only overlapped by the lining, and when combined, a gap may form, as a result of which the sharp edges of the hob in the front of the product will ultimately remain open.

In the oven door, which contains two hinges, a handle, two stamped parts mounted one opposite the other, and a corner finish, the connection of these parts is usually done by at least four rivets that remain open, impairing the appearance of the product, and in the process work may endanger the user.

Document PI 9600036 8A describes a system for assembling cooker components and describes in detail a fastening system for an intermediate hob, but does not mention stamped locking elements and clamps in this document.

No. 2,533,797 describes locking-type connecting devices with transverse openings that are arranged on the connecting parts, rather than stamped directly on the connected parts.

Disclosure of invention

The present invention relates to a system for connecting components of a cooker, consisting of stamped locking elements and holes, due to the shape, size and placement of which the manufacture and assembly of the stove is simplified, without the need for tools and devices for connecting the hob to the side walls of the stove , to connect the hob to the front plate and to assemble the oven door of the stove.

The implementation of the invention

The invention relates to a system for connecting components of a cooker, consisting of a number of holes 2 and a number of locking elements 1, stamped on the connected components of the stove. Such a system is designed to connect the hob 3 to the walls 4 of the stove, as shown in FIGS. 1-4, as well as to connect the hob 3 to the front cover 5, as shown in FIG. 5, and to connect the two components 6a and 6b the oven door of the stove, as shown in FIG. 6.

In one embodiment of the invention, the side wall 4 of the cooker is provided with a locking element 1, which has the shape of a hook, as shown in FIGS. 1A and 2E, made by stamping on the top side of the stacks 4, and on the downward side of the hob 3 of the cooktop the hole 2 corresponding to the locking element 1, located on the side wall 4 of the stove, as shown in figa. Thus, the hob 3 is blocked by the side walls 4, and when it is moved a few centimeters backwards, the connected components of the stove are fixed in the vertical direction, and their reverse movement is limited, as shown in FIGS. 2A and 1C. After that, the back of the hob 3 is attached to the chamber with only two screws.

In an alternative embodiment of the invention, a reverse connection system may be used to connect the hob 3 to the side wall 4, namely, the hole 2 is provided on the side wall 4, and the hook-shaped locking element 1 is provided on the hob 3, as shown in FIG. 3A. The connection and fixing of the components of the stove shown in figa and 4C, is the same as in the previous embodiment of the invention.

According to another embodiment of the invention, the hob 3 of the stove comprises two or more locking elements 1 in the form of hooks, made by stamping on its front lower side and wrapped inward, as shown in figs, while on the upper protrusion of the lining 5 there is a groove with two holes 2 corresponding to the locking elements 1 of the hob, as shown in fig.5D. When the plate 5 is engaged with the protrusion of the hob 3, it is moved a few millimeters in the lateral direction, while the connected components are fixed in the horizontal direction without forming a gap, as shown in fig.5D. After that, the pad 5 in its lower part is attached to the camera with two screws. With this combination of cooker components, sharp edges on the front cover are eliminated, which contributes to the safety of the user and improves the appearance of the equipment.

According to a third embodiment of the invention, the connection system can also be used when assembling the oven door of the stove, in which, as shown in FIG. 6C, the outer part 6a of the oven door contains two locking elements 7 which are formed by stamping on its upper side and during assembly aligned with two holes 8 made in the upper rim of the inner part 6b of the door, as shown in figs. Thus, the two door parts 6a and 6b are engaged and connected along the upper side of both parts 6a and 6b, after which the outer part 6a is fastened to the inner part 6b in the lower part of the door with three rivets. Thus, there are no rivets at the top of the oven door.

The scope of the present invention is not limited to the above description and the attached drawings. Numerous changes and various modifications of the invention are obvious to those skilled in the art to which the invention relates, based on the idea disclosed in the above description and the accompanying drawings. In addition, it should be understood that the invention is not limited to a specific form of the connecting system, and changes and various forms of elements of the connecting system are possible within the scope of the claims.
