Description

Technical field

The present invention relates to a hinged door element for a refrigeration apparatus, in particular a domestic refrigerator.

State of the art

On the inside of such a door, several hinged elements are usually installed, for example hinged boxes, an oil container, etc. Such hinged elements to a large extent determine the appearance of the household appliance perceived by the user. This applies not only to built-in household appliances, in which the user during operation sees only the internal surfaces of the storage chamber, but also to outdoor household appliances with visible external surfaces.

If a manufacturer makes various series of refrigeration units, then, on the one hand, it will be rational to use the maximum possible number of components, unified for all series, which will reduce production costs, and, on the other hand, it is necessary to give individual series recognizable attributes to different series or models . To do this, it is proposed to unify the production of cases of refrigerating appliances and to change the appearance of the mounted elements depending on the model or series. A variant in which the hinged elements are molded under pressure essentially as a solid part, although it is characterized by a large variation in design, is relatively expensive, since expensive molds are required for each individual hinged element.

As part of the search for a cheaper solution, a modular design has already been considered in which the components of the door hinge (for example, the bottom and side walls) are made separately and assembled into a finished hinged element. This design allows the manufacture of attachments of various sizes, combining the same side walls with bottom plates of various lengths. To give different models of refrigeration units an individual look, it may be sufficient to combine the side walls specific to each unit with bottom plates, unified for all models.

Such a solution is cheaper than manufacturing as an integral element, but its potential for savings is limited. This is due to the fact that the side walls, as a rule, have a more complex shape than the components of the hinged door element located between them, as a result of which the individual forms necessary for their manufacture are still quite expensive.

Disclosure of invention

The objective of the invention is to develop a hinged element for the door of the refrigerator, the appearance of which can be fundamentally changed at low cost.

The problem is solved due to the fact that an insert is inserted into the cavity of the door hinge for the refrigeration apparatus, which contains the bottom plate and the hollow side walls connected by the bottom plate, to the cavity of at least one of the transparent, in particular glass transparency side walls. Using different options for the liner, you can give the same side walls and, thus, the hinged elements of the door to which they belong, noticeable individual signs. The insert may have a significantly simpler shape compared to the side walls into the cavity of which it is installed. Due to this, the manufacture of various options for the liners will cost much less than the manufacture of various options for the side walls. In addition, the use of inserts allows you to get significantly different door hinges, which will all have a single, unified for all models and cheap (thanks to the production of large series) case, combining at least the side walls and the bottom plate.

If the insert is clamped into the cavity or enters the cavity with such a small gap that deformation caused by the load of the door hinge element during normal operation leads to the clamping of the insert, then the insert will further contribute to increasing the rigidity of the door hinge element and its stabilization. This will ensure the necessary load-bearing capacity of the door hinge element with a lower material thickness compared to the door hinge element without the liner, as a result of which the cost of the liner can be at least partially offset by such material savings.

The cavity may be open in a known manner downward.

In order to prevent the insert from falling out of the cavity open downwards, if the insert is not clamped or if the temporary deformation of the door hinge element may disappear, the insert is expediently fixed in the side wall.

A known design in which on the outer side of the hollow side wall is provided a receiving groove for the support cam, which holds the hinged element on the door of the refrigerator. Deformation of the side wall around the receiving groove under load may impair the reliability of the landing of the door hinge. In order to stabilize the receiving groove, the liner is preferably made so that it lies against the facing surfaces of the groove and the opposite inner wall.

In particular, the hinged element of the door can be made in the form of a hinged box with a front wall that connects the side walls.

Preferably, such a front wall is made integrally with the side walls and has the same transparency (transparency of the glass) as the side walls. Due to this, refrigerated products placed in the hinged drawer can also be seen through the front wall.

A profile element mounted on the upper edge of the front wall can serve either only for decoration, or also for stiffening the front wall.

From a design point of view, it is desirable that the lower edge of the insert is at the same level as the lower edge of the profile element, so that the profile element will appear to the user as a continuation of the insert.

Alternatively, the door hinge may be in the form of an oil container, in particular a container with a hinged lid located between the side walls.

The implementation of the invention

The hinged box shown in figure 1 consists of a solid body 1, injection molded from plastic with glass transparency (for example, polystyrene or polymethyl methacrylate), a profile element 2 and inserts 3.

The housing 1 is essentially in the form of a rectangular box open at the top with a front wall 4, which, when the hinged box is mounted on the refrigerator door in a known manner, faces the opposite side of the door, with the back wall 5 facing the refrigerator door, a bottom plate (not shown on figure) and two side walls 6, between which the walls 4, 5 and the bottom plate are enclosed. The side walls 6 are hollow and open downward (see FIG. 2), and the inserts 3 are designed so that they can be inserted with low tolerance from below into the cavities of the side walls 6. In this case, the inserts 3 have the shape of an angle with a vertical arm 7, which located near the rear wall and has a height exactly corresponding to the height of the cavity of the side walls 6, as well as a horizontal shoulder 8 that protrudes forward, the lower edge 9 of which extends at the level of the step 10, which extends along the outer sides of the side walls 6 and the front wall 4.

While at the side walls 6, the upper section 11 above the ledge 10 protrudes slightly outward above the lower section 12 located below it, at the front wall 4, the upper section 13 above the ledge 10 is slightly shifted back relative to the section 14 located below it.

The profile element 2 is made so that it can be worn on top of the upper section 13 of the front wall 4 and at the same time be fixed on the rib protruding inward from the upper edge of the section 13. In the locked state, the outer plate 15 of the profile element 2 exactly fills the upper section 13, and the free surface of the outer plate 15 is flush with the adjacent sides 11 of the side walls 6. As a result, the profile element 2 seems to the user to be an extension of the horizontal shoulders 8 of the liners 3, which s visible inside the transparent sidewalls 6.

Figure 2 shows more precisely the structure of the side walls 6 and the liners 3 placed therein. Each of the side walls 6 contains an inner wall 16, the edges of which are connected integrally with the walls 4, 5 and the bottom plate 17. The outer wall 18 of the side wall 6 is connected by its the front edge with the inner wall 16 and the front wall 4, and its upper edge with the horizontal cover plate 19. The lower and rear edges of the outer wall 18 are not connected to anything. The trailing edge of the outer wall 18 is reinforced with an inwardly bent rib 20. A receiving groove 21 adjacent to the rib 20 is formed in the outer wall 18 for the support cam of the refrigerator door.

The figure 3 shows a section of the side wall 6 and the liner 3 mounted therein in a vertical plane passing through the receiving groove 21. A fixing hole 23 is made in the wall 22 of the receiving groove, which engages with the locking protrusion 24 of the liner 3. The upper end of the wall 22 is bent and, instead of the cover plate 19, is connected directly to the inner wall 16, increasing the rigidity of the side wall 6. The liner 3 exactly fills the intermediate space between the wall 22 and the inner wall 16 of the side wall, and thus m, contributes to the rigidity and load capacity of the side wall 6.

In figure 2, on the outside of the vertical shoulder 7, a groove 25 is visible, into which a rib 20 of the outer wall 18 enters with a geometric closure.

The liner 3, as well as the housing 1, is a die-cast hollow element. Between the two open cavities 26, 27 that extend down the entire height and width of the liner 3, a wall 28 extends, forming the front end of the vertical arm 7. In addition, this wall holds the walls 16, 18 of the side wall 6 in a predetermined position relative to each other.

Depending on the manufacturing technology of the cavity 29 of the side walls 6 and the cavity 26, 27 of the insert 3 expand downward, as shown, in particular, in figure 4.

The figure 5 presents a cross section showing the fixing of the profile element 2 on the jumper 31, protruding inward from the upper edge of the front wall 4, and the alignment of the lower edge 9 of the horizontal arm 8 relative to the lower edge of the installed profile element 2 and the ledge 10.

The concept of the invention, providing for changing the appearance of the door hinge element by means of inserts inserted in the hollow transparent side walls, can equally be transferred to the oil container, as shown in figure 6. This figure shows a similar oil container with a lid 30, suspended with the possibility of rotation between the side walls 6 and located in a partially open position. In this case, the lid 30, like the front wall 4 of the hinged drawer (see FIG. 1), has a ledge 10, and, of course, as on the side walls, the region located above the ledge 10 protrudes above the region below. The inserts 3 are identical to the inserts shown in figure 1, that is, the lower edges 9 of their vertical arms 7 with the lid 30 closed are located at the level of the ledge 10. Alternatively, the insert could be in the form of a substantially flat square (see the dotted outline in the figure 6), which would fill the side wall 6 over the entire height and width.
