Description

This invention relates to a washing / drying machine that provides easy assembly and the prevention of damage that may occur during transportation.

In washing / drying machines, the outer casing is formed by connecting the rear, side and front walls with fasteners such as screws, etc. These screws and fasteners are acted upon from various directions of force during impacts, capsizing, which can occur during transportation. In cases where screw connections cannot withstand these forces, deformations or ruptures of the metal sheet in these zones can occur. In the prior art, various methods are used to ensure easy assembly of the outer casing and to prevent damage at the joints.

US2004 / 0244439 describes a home machine that allows for easy assembly. On the side and rear panels of the housing there are protrusions and holes. The protrusions on the side panels are inserted into the holes on the front panel to secure the front panel. The housing is fully locked by mounting the bracket in the base of the hole in the groove on the underside of the protrusion.

U.S. Patent No. 2004/0107738 describes an improvement in the assembly of a front panel with side panels. Flanges on the side panels are inserted into the recesses on the front panel for mounting. Since several recesses are provided, the stress concentration in each connection is reduced.

The aim of this invention is the implementation of a washing / drying machine, which provides easy assembly and which reduces damage that can occur during transportation.

A washing / drying machine implemented to achieve the objectives of the present invention is characterized in the claims.

In the washing / drying machine according to the invention, at least one slot is located on both sides on the inner surface of the front wall, and grips corresponding to these slots are provided on the side walls for mounting the front wall on the side walls.

The grips used in a preferred embodiment of the present invention comprise a hemispherical head and a neck that connects this head to a side wall. On the other hand, the slots located on the front wall are made wide enough for the head to pass in the upper part, while the lower part is made narrow as a neck. In this embodiment, the passage of the head into the slot is achieved by inserting the head into the wide portion of the slot and sliding the front wall up to fit the neck in the narrow portion of the slot. Thus, the grip rests on the lowest point of the slot. The lower side of the slot serves as a barrier to prevent the front wall from moving in the upper direction.

Locking the front wall after attaching the side walls to it is carried out using convexities formed each opposite to each other on the front wall and side walls. The bulges are designed to slide on top of each other during the locking of the front wall and to ensure such locking that movement in the opposite direction is excluded after installing them in place.

In a preferred embodiment of the invention, the bulges are formed by an operation performed on a metal sheet of the front and side walls. The protruding part forms a bulge due to the passage to the other side of the wall during the extrusion process. The bulge contains a sliding surface on which they rest against each other before locking the front wall with the side walls. When the front wall slides to provide locking, the bumps slide along each other along the sliding surfaces. In addition, the bulges contain a supporting surface along which they abut against each other when the front wall is locked with the side walls. When the locking process is completed, the supporting surfaces of the bulges overlap each other by being located opposite each other and prevent movement in the direction opposite to sliding.

During assembly, the front wall is first attached to the side walls by passing bulges on the front wall into the slots on the side walls. Then the bulges are passed over each other by sliding the front wall with tension while holding the bulge on the front wall above the bulge on the side wall. Although the rear sides of the bulges tilted outward are supported against each other before sliding, the forces that can act from different directions during transport are more effectively compensated, since the up and down sides are opposite to each other in the locked position.

In one embodiment of the invention, the side walls are attached to the base and to the cover using additional fasteners (rivets, screws, etc.) after the assembly of the front wall with the side walls is completed.

The washing / drying machine 1 comprises at least two side walls 2, which cover the volume containing the drum into which the laundry is placed, and other machine elements on the sides, the front wall 3 attached to the side walls 2, at least , one slot 4 located on the inner surface of the front wall 3, for mounting the front wall 3 on the side walls 2, and at least one grip 5 located on the outer surface of the side walls 2, for mounting the front wall 3 on the side walls 2 through in reference into the slot 4.

In addition, the washing / drying machine 1 contains bulges 6, 60 located opposite each other on the front wall 3 and side walls 2 facing each other, which slide on top of each other during installation of the front wall 3 on the side walls 2 and provide locking by prohibiting reverse movement after fixing in place of the front wall 3.

The grips 5 can be made in the form of a hook, a pin, a bracket, etc., consistent with the shape of the slot 4.

The grips 5 used in the preferred embodiment of the present invention comprise a hemispherical head 8 and a neck 9 with a width smaller than the diameter of the sphere that connects this head 8 to the side wall 2. In this embodiment, the upper part of the slots 4 into which the grips 5 are mounted is wide enough for the introduction of the head 8. The lower part of the slots 4 is wide enough to fit the neck 9, however, has a size that does not allow the passage of the head 8. Therefore, the grip 5 is introduced through the wide part of the slot 4 so that the head 8 extends beyond the front wall 3. Then, the front wall 3 is slid upward to fit the neck 9 in the narrow part of the slot 4.

The bulge 6, 60 formed on the front and side walls 2, 3 using the extrusion process. The parts extruded during the extrusion process form a convexity 6, 60. The convexities 6, 60 comprise a sliding surface A on which they rest against each other before locking the front wall 3 with the side walls 2. The convexities 6, 60 slide along each other along the surface A slip when the front wall 3 slides to provide locking. The sliding surface A can be either parallel to the plane formed by the bulges 6, 60, or can be inclined. The bumps 6, 60 contain a supporting surface O, on which they abut against each other after locking the front wall 3 with the side walls 2. After the locking process is completed, the supporting surfaces O of the bumps 6, 60 overlap each other opposite to each other and prevent movement in the direction opposite to sliding. The supporting surface O is almost vertical relative to the plane in which the bulges 6, 60 are formed.

Grips 5 restrict the movement of the front wall 3 back and forth. The downward movement of the front wall 3 is prevented by the locking provided by the bulges 6, 60.

In one version of this embodiment, the sliding surfaces A of the protuberances 6 on the front wall 3 are inclined downward; the sliding surfaces A on the bulges 6 on the side walls 3 are inclined upward. The sliding surfaces A of the opposite convexities 6, 60 are supported against each other before the locking operation, therefore, the convexity 6 on the front wall 3 is almost at the same level with the convexity 6 on the side wall 2 or somewhat lower.

To assemble the front wall 2 with the side walls 3, the grips 5 are first introduced through the slots 4 on the side walls 3. Then the bulges 6, 60 are passed over each other by stretching the front wall 3 to slide upward while holding the bulge 6 on the front wall 3 above the bulge 60 on side wall 2. In this position, the supporting surfaces O located at the ends of the bulges 6, 60, separating the surface of the front wall 3 and the side wall 2, are aligned and at least partially supported by each other. Thus, locking of the front wall 3 is ensured, and the front wall 3 is connected to the side walls 2 without the need for a separate support from the outside.

In one embodiment of the invention, the side walls 2 are attached to the base and cover using additional fasteners (rivets, screws, etc.) after the assembly of the front wall 3 with the side walls 2 is completed.

In the washing / drying machine 1 according to the invention, in the event of excessive loads during transportation, the load is distributed to the grips 5 and the bulges 6, 60 on the front wall 3 and side walls 2, which prevents the lower side connected by the fastening elements 7 from being separated.
