Description

Technical field

The present invention relates to a refrigerating apparatus, in particular a domestic refrigerating apparatus with a door, on the inside of which a hinged or built-in element is installed.

State of the art

On the inside of the door of such a refrigerator, usually several hinged or built-in elements are installed, for example containers for refrigerated products, an oil compartment, etc. Such built-in elements significantly affect the appearance of the refrigerator, perceived by the user. This applies not only to the built-in refrigeration unit, in which the internal surfaces of the storage chamber are the only surfaces of the refrigeration unit that the user observes during daily use, but also to floor-mounted refrigeration units with visible external surfaces.

When a manufacturer produces various series of refrigeration units, it will be rational to use the maximum number of components unified for all series to reduce production costs. On the other hand, different series or models must have individual attributes recognizable by the user. To achieve such a result, it is proposed to unify the manufacture of cases of refrigerating appliances as much as possible, and the integrated elements to vary depending on the model or series. If the built-in elements are molded under pressure, essentially in the form of an integral element, then, despite the great freedom of design, it is necessary to bear the cost of molds for each specific model of the mounted or built-in element. That is, such a concept is relatively expensive.

When looking for a cheaper solution, a modular design was already considered in which the components of the hinged or built-in door element, such as the bottom plate and side walls, are made separately, after which the built-in door element is assembled from them. This option allows the manufacture of built-in elements of various sizes due to the fact that the same side walls are combined with bottom plates of different lengths. To give different models of refrigeration units their individual characteristics, it may be sufficient to combine the side walls specific to the refrigeration unit with standardized bottom plates.

Although this design is already cheaper, the potential savings are limited by the fact that the side walls are generally more complex than the components of the hinged or built-in door element between them. As a result, the individual molds required for their manufacture are still quite expensive.

Disclosure of invention

The objective of the invention is to develop a hinged or built-in 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 in a refrigerator, in particular, a household refrigerator with a hinged or built-in door element, which comprises a bottom plate and side walls connected by a bottom plate, at least one of the side walls, and preferably both side walls are lined decorative element. Since the installed decorative element does not have to perform load-bearing functions, it can have a small wall thickness and, accordingly, low cost. Since the decorative element should also not be used to fasten the hinged or built-in element to the door, it can have a simple shape, that is, simple and inexpensive molds can be used for its manufacture. On the contrary, for different models or lineups, unified side walls can be used, which makes it possible to produce these walls in large batches at low cost.

In addition, preferably, the side walls are connected by a side, which makes it possible to obtain a hinged or built-in element with an open upper side, which is usually called a hinged element of a door and serves, in particular, for storing bottles in an upright position.

A decorative element can also be worn on the side of such a hinged or built-in door element, which allows you to change the appearance of the side.

Alternatively, a cover (with a possibility of rotation) can be installed between the side walls of the hinged or built-in door element, which makes it possible to obtain, for example, an oil compartment.

It is advisable that the decorative element of the side walls should cover their most noticeable surfaces, that is, the front, upper and outer sides.

According to a first embodiment, the decorative element also covers the inside of the side wall. Such a decorative element can be worn on the side wall essentially from above.

To fix the decorative element on the side wall with a geometric closure, on the lower edge of that side of the decorative element that covers the outer side, it is advisable to form an inwardly protruding rib.

Decorative elements worn on the side walls can be used to fix a decorative element worn on the side. To do this, it is advisable that the inner sides of the decorative elements worn on both side walls converge in the forward direction, and the decorative element worn on the side has a dovetail-shaped jumper, which is fixed with a geometric closure between the inner sides.

According to a second embodiment, the decorative element further covers the front, upper, outer and lower sides of the side wall. Such a decorative element can most easily be worn on the side wall in front.

Preferably, a jumper is formed on the side walls with a geometric closure on the lower and / or upper side of the decorative element, which engages with the inner side of the side wall. This second embodiment is particularly suitable for an oil compartment in which a closed lid may make it impossible to put on a decorative element on the side walls from above.

In the rear part of each outer side, fixing contours are usually provided, designed to engage the hinged or built-in door element with the geometric refrigerator door. It is advisable that this back region in the decorative element be cut out.

An actuating element may be provided on the outside of the side wall, which, for example, can be pressed to open the engagement between the support protrusion of the hinged or built-in door element and the corresponding recess of the door. As a result, it will become possible to disconnect the built-in element from the door. Such an actuator can be completely hidden by a decorative element. Therefore, if you want to use the actuator, you must first remove the decorative element. Alternatively, a tongue covering the actuator may be cut out in the decorative element. The user can click on this tab to push the side wall actuator.

The implementation of the invention

Figure 1 presents an exploded perspective view of a hinged or built-in door element according to the first embodiment of the invention. The main element 1 of the hinged or built-in door element is essentially in the form of an elongated, open upward duct with a bottom plate 2, as well as a front wall 3 and a rear wall 4, which are located along the longitudinal sides of the bottom plate 2 (in the framework of the proposed description " front "means the direction away from the door of the refrigerator, not shown in Fig. 1, on which the built-in element or component is installed, and the" back "is the direction to the door). The rear wall 4 in the mounted state is adjacent to the inner surface of the door of the refrigerator or, in any case, is separated from it by a narrow gap. Therefore, it serves only to stiffen or stabilize the main element 1 and is not used as a support holding refrigerated products installed in the embedded element.

The bottom plate 2 and the walls 3, 4 are located between the two side walls 5. Each of the side walls 5 contains a front section 6, which has a substantially hollow, rectangular parallelepiped open shape and a rear section 7 whose shape is designed for engagement with known vertical rails extending along the inside of the refrigerator door. The rear section 7 has openings on the lower side of the recess 8, which should be mounted on the supporting protrusions facing each other of the sides of the vertical rails. Thus, the hinged or built-in door element is mounted on the rails. In this case, the rear portion 7 is made in the form of a thin solid plate, from the outer side of which there are ribs 9, limiting the recess 8.

The side walls 5 can be molded under pressure from plastic as a whole with the bottom plate and walls 3, 4, or they can be molded separately from the bottom plate 2 and walls 3, 4, and then connected to them, preferably by the plug-in method. In the latter case, the bottom plate 2 and the walls 3, 4 can be made in the form of a single extruded profile or in the form of separate extruded profiles that are connected to each other directly or by means of side walls 5.

In particular, the last (composite) embodiment allows the use of material for the side walls 5, for which the bearing ability and the ability to be machined are important, but the appearance is not important, since the side walls 5 of the finished built-in elements are not visible to the user, but are completely hidden by decorative elements 10 worn on top of them.

Decorative elements 10 are thin-walled hollow elements of painted or metallized plastic or metal, in particular aluminum. These elements are worn on the side walls 5 from above. Each decorative element contains an outer side 11, which covers the outer side of the front portion 6, an inner side 12, which is included in the main element 1 and covers the inner side of the side wall 5, the upper side 13, which connects the side sides 11, 12, and the front side 14 which is adjacent to the upper side 13 and the outer side 11. The front side 14 and the inner side 11 are separated by a gap 15, through which the front wall 3 of the main element passes. Another decorative element, not shown in the figure, can be worn on this front wall, which will completely or partially cover the front side of the wall 3. It is advisable that the material or at least the surface of this second decorative element is identical to the material or surface of the decorative element 10.

The figure 2 presents the assembled built-in door element. Decorative elements 10 do not cover only the outer sides of the rear sections 7 of the side walls 5 adjacent to the vertical slats of the door, and the lower sides of these sections. The open lower sides, as a rule, are not visible to the user, since the built-in door element, as shown in figures 1 and 2, is installed essentially below eye level.

Figure 3 presents a schematic section of a side wall 5, open from the lower side, and a decorative element 10 worn on it. On the lower edge of the outer surface 11, a narrow rib 16 is bent inward, which is adjacent to the lower edge of the outer side of the side wall 5. The rib 16 fixes decorative element 10 on the side wall 5 with a geometric closure. At the same time, the thin outer side 11 is flexible enough so that the jumper, under the action of upward force, deviates outward and releases the decorative element 10.

Figure 4 presents a horizontal projection of the front corner of the hinged or built-in door element, made according to a different embodiment. Figure 5 presents a section along the line V-V, indicated in figure 4. The front wall 3 of the main element 1 is hidden behind a worn decorative element 37 having the shape of an extruded profile. The decorative element is made of the same material or has the same surface coating as the decorative element 10. The cross-section of the decorative element, as shown in figure 5, is essentially C-shaped. That is, there is a central portion 38 covering the outside of the wall 3, and jumpers 39, 40 bending backward from its upper and lower edges.

The side walls 5 and the decorative elements 10 worn on them are made mirror symmetrically to each other, and their sides facing each other, as shown in Fig. 4, converge in the forward direction. The jumpers 39, 40 on the horizontal projection expand backwards in the form of a dovetail, due to which they are fixed between the decorative elements 10 with a geometric closure. To assemble the built-in door element, you must first put the decorative element 37 on the front of the wall 3. When subsequently the decorative elements 10 are worn on the walls 5, the decorative element 37 is fixed on the wall 3.

Figure 6 presents an exploded view of the hinged or built-in door element according to the second embodiment of the invention, similar to figure 1. In this case, the main element 1 is completely identical to the element shown in figure 1. Decorative elements 17 are arranged so that they are pushed onto the side walls 5 in the direction of the depth axis. The decorative elements 10 do not have an inner side 12, but a lower side 18 is added, which, when worn, completely covers the lower side of the side wall 5. On the inner edges of the upper side 13 and the lower side 18, narrow ribs 19 are formed that engage with the inner surfaces of the side walls 5. The ribs 19 do not reach the front side 14 of the decorative elements 17 to leave room for the front wall 3.

This second embodiment is particularly suitable for a container for refrigerated products, which is installed approximately at the eye level of the average height of the user, since the probability that the user sees the lower side of the hinged or built-in door element 7 is higher than the probability that the user will be able to view the built-in element from above and notice the uncovered inner surfaces of the side walls 5.

On Fig presents a perspective view of the compartment for oil, which is made according to the invention and contains a housing 20 and a cover 21 mounted on the housing 20 with the possibility of rotation around a horizontal axis. Cover 21 is shown in a partially open position. In the closed position, the cover is flush with the front sides of the side walls 5 of the housing 20, and in the open position is located essentially in a horizontal plane directly above the cover 22 of the housing 20.

Decorative elements 23 are made similarly to decorative elements of the second embodiment and comprise an outer side 11, a front side 14, an upper side 13, and a lower side 18 that cover all surfaces of the side walls 5 that are visible when the cover 21 is closed. In addition, these elements contain ribs 19 which from the upper and lower sides engage with the inner surfaces of the side walls 5.

Unlike previous versions, the oil compartment housing 20 does not have recesses 8, which include the supporting protrusions of the vertical rails of the refrigerator door. Instead, a protrusion 24 is formed in the rear portion 7, which enters the corresponding recesses of the vertical rails. The protrusion 24 can elastically move along the axis of the width of the oil compartment, if you click on the actuating element 25, freely located on the front section 6 of the side wall 5. The actuating element 25 and the protrusion 24 can be components of a single elastic tongue, which extends inside the side wall 5 along depth axis.

If a decorative element having the shape shown in Fig. 6 is put on the side wall 5 (with the outer side 11 closed), the actuating element 25 will not be available and accidental disconnection of the oil compartment will be excluded.

Fig. 8 shows a different embodiment in which an elastic tongue 26 is cut out on the outside 11 of the decorative element 23. When the decorative element 23 is worn on the side wall 5, the tongue 26 completely overlaps the actuating element 25. When the tongue 26 is pressed, it can be pressed and an actuating element 25, as a result of which the protrusion 24 can be withdrawn from the corresponding locking recess of the refrigerator door, which will allow you to disconnect and remove the oil compartment.

Of course, the actuating element 25 and, if necessary, the tongue of the decorative element overlapping the actuating element can also be provided in the versions of the hinged or built-in door element shown in figures 1-7.
