Description

Technical field

The present invention relates to a refrigerating apparatus, in particular a domestic refrigerating apparatus with a built-in element, designed to be installed on the door of a refrigerating apparatus, in particular a domestic refrigerator.

State of the art

On the inside of such a door, in most cases, usually there are several built-in elements, for example compartments for refrigerated products, an oil container, etc. In most cases, vertical slats are formed on the inner surface of the door leaf on which the built-in elements are supported by their contours formed on the side walls of the built-in elements.

There is a known variant in which the side walls of such a built-in element are made in the form of hollow elements containing an internal wall element, an external wall element and a downwardly directed hole formed when removed from the mold, and the internal wall element in the installed state enters the space between the door rails and contains supporting contours, and the outer wall element terminates at the front edge of the rail. The external wall element contributes to a relatively small extent to the load capacity of the built-in element, since it is prone to bending outward under load.

Disclosure of invention

The objective of the invention is to develop a built-in element for the door of the refrigerator, which will be characterized by ease of manufacture and high load capacity at low material consumption.

The problem is solved by a built-in element of the indicated type, in particular a hinged door element, which contains a bottom plate and hollow side walls connected by a bottom plate, the side walls having a closed lower side and the hole in the side walls formed when removed from the mold is located on back side of the built-in element facing the door. The closed lower side does not allow the outer wall of each of the side walls to bend outward under load. There is no risk of bending at the edge of the hole formed when removing from the mold and facing the door, or, in any case, is significantly reduced compared to the usual downward opening formed when removing from the mold, since the stresses in the wall elements the side walls due to the load of the built-in element are directed essentially perpendicular to the edge of the hole formed when removed from the mold, and therefore do not contribute to the bending of the edge.

Preferably, the hollow side walls are open only from their rear side facing the door.

If at least the side walls of the built-in element are made of a transparent, preferably glass-transparent material, then it becomes possible to change the appearance of the built-in element at low cost by placing the insert in the side walls. Thus, in a simple and inexpensive way, you can significantly change the design of built-in elements that can be used in various models or model ranges of refrigerators. Since the liners inside the side walls are protected, strict requirements should not be imposed on the wear resistance of their surface. In particular, in order to create the appearance of a metal, metallized surface liners made of an inexpensive material, in particular plastic, can be used.

In order to enable fixing of the built-in elements on the door and their removal from the door, the side walls may contain a horizontally movable holding element, in particular a support protrusion, which serves to support the built-in element, in particular in the recess of the door. Alternatively, the retaining element itself may comprise a recess that interacts with the abutment protrusion on the door, providing vertical support for the built-in element on the door.

Alternatively, the liners can perform a static function due to the fact that such a support protrusion is formed on the liners. This option is advantageous, in particular, because if the support protrusion is damaged, the insert can be easily replaced, and the rest of the built-in element can still be used.

Preferably, such a liner comprises an elastic tab on which a support protrusion is located.

Preferably, on the side wall there is a window in which the pressure portion of the elastic tongue is freely located. Thus, the user can actuate this pressure section (click on this section) to remove the support protrusion from the recess of the door or to insert the support protrusion into the recess.

Vertical recesses can be formed on the outer sides of the side walls, which can include guide doors facing each other, thereby forming a rail for the built-in element, which allows you to change the installation height of such an element on the door without simultaneously disconnecting it from the door.

To avoid unnecessarily complicating the traditional method of manufacturing the inside of a door by deep drawing, the guides included in the recesses are preferably made separately and mounted on the door.

Since technological guides related to the deep drawing method do not apply to these guides, it is possible to form recesses for supporting protrusions in the thick ledges of the guides without problems. Therefore, it is advisable that the supporting protrusions of the embedded element are included in the vertical recesses of the side walls of this element.

If the built-in element should serve as a hinged element of the door, then its side walls are expediently connected by a side.

A decorative element can be worn on this side.

Preferably, the decorative element is mounted on the rear side of the side, made of a transparent material, in particular with a transparency of glass material, that is, it is protected to the same extent as the liners of the side walls. Thus, the same requirements are imposed on the design of the visible surfaces of a decorative element as on the inserts (and the same design possibilities open up).

Preferably, the rim has the shape of a vertical wall, from the rear side of which a horizontal rib protrudes. This rib serves not only to stiffen the wall, but also, preferably, to fasten the decorative element, and preferably the decorative element contains a U-shaped profile worn on the rib.

So that it is not evident to the user that the decorative element is not part of the rim, the upper shoulder of the U-shaped profile is preferably flush with the upper edge of the wall.

To enhance the impression of a solid wall and fix the decorative element on the wall, it is advisable that the plate of the decorative element completely occupies the rear side of the wall between the rib and the bottom plate.

Additionally, in order to fix the decorative element on the rib, an undercut may be formed into which the plate enters.

A container, which is essentially called an oil container and includes a hinged lid mounted between two side walls with the possibility of movement, in particular rotation, is also considered as a built-in element.

The implementation of the invention

1 is an exploded perspective view of a door hinge according to a first embodiment of the invention. The main element 1 of the door hinge element is essentially in the form of an elongated, upwardly open box 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. Moreover, in the framework of the proposed description, "front" means the direction away from the refrigerator door, not shown in figure 1, on which the hinged element is installed, and "rear" is the direction to the door. The rear wall 4 in the mounted state is adjacent to the inner surface of the refrigerator door 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 (unlike the front wall 3) as a side holding the cooled products installed in the mounted 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, as shown, in particular, in section in figure 3, has a substantially hollow shape, open from the side a rear opening 32 (formed due to extraction from the mold) of a rectangular parallelepiped or, more precisely, a truncated prism with an internal wall element 50 and an external wall element 30. These wall elements to a small extent converge towards each other in the forward direction and are connected by the front side surface 13, the upper side surface and the lower side surface 33. The convergence of the elements 30, 50 of each side wall 5 facilitates removal from the mold through the hole 32 in the manufacture of the main element 1 in the form of an integral part by injection molding of plastic.

The rear portion 7 of each side wall 5 is formed so that it enters the space between the vertical rails that extend along the inside of the refrigerator door. Each rear section 7 contains a recess 8 open to the bottom, intended for landing on the supporting protrusions of the side surfaces of the vertical rails facing each other, and thereby for fixing the door hinge to the rails. In this case, the rear portion 7 is made in the form of a thin massive plate, from the outer side of which there are ribs 9 that limit the recess 8.

The main element 1 is made of a polymer material having glass transparency, for example polystyrene or polymethylmethacrylate, so that the inserts 10, intended for installation in the hollow side walls 5 through an opening on the rear side of each side wall, remain visible in the side walls 5.

Since the liners 10 located in the side walls are protected from abrasion, scratching, etc., their surface does not require special wear resistance. Thin surface metallization of the liners 10 together with the shiny surface of the side walls 5 will be enough to give the impression of a shiny metal surface. Depending on the aesthetic preferences and price category of the model of the refrigeration apparatus that uses the hinged door element, inserts 10 of a different color can be used, for example, made of white plastic, or the side walls 5 can be left completely empty.

The front wall 3, as well as the surface of the side walls 5, has glass transparency and does not close with anything in the embodiment shown in figures 1 and 2. To ensure sufficient rigidity of the wall 3 with a small thickness, an edge 11 is formed on the upper edge of the wall, directed back to horizontal plane.

Figure 4 shows that this rib 11 can be used to mount an externally mounted decorative element 12, which is made in the form of a metal or plastic extruded profile. If such a decorative element 12 is provided, then preferably the outer surface of the front wall 3, as shown in FIG. 3, does not reach slightly to the front side surfaces 13 of the side walls 5, so that these side surfaces 13, when the decorative element 12 is installed, are arranged flush with this element.

According to a preferred embodiment, the decorative element 14, as shown in section in figure 5, is mounted on the inner surface of the wall 3. The decorative element 14, which is also made in the form of an extruded profile, contains a substantially flat plate 15, which occupies the inner side of the wall 3 from the bottom plate 2 to the lower side of the rib 11, and the U-shaped profile 16, which is formed on the upper edge of the plate 15 and covers, clamping, the rib 11. The outer side of the upper shoulder of the U-shaped profile 16 is flush about with the upper edge of the wall 3. The lower shoulder of the U-shaped profile 16 connected to the plate 15, is included in the open bottom cutout 17 on the lower side of the ribs 11, which ensures the fixing of the decorative element 14 with a geometric closure. Since the decorative element 14, essentially, can only be seen through the transparent material of the wall 3, its surface may look the same as the surfaces of the liners 10 in the side walls 5.

6 is an exploded view of a door hinge according to a second embodiment. As in the first embodiment, the main element 1 (in the form of a box) of the hinged door element has side walls 5, which contain hollow front sections 6. In the cavity of the side walls 5 through the rear holes can be inserted into the form of suitable inserts 20. The rear sections 7 of the side the walls 5 have one recess 18 extended in the depth direction and open backward and to the side, into which the C-shaped protrusion 19 of the insert 20 enters. In the upper and lower lateral surface 21, 22 of the protrusion 19, one recess 23 is formed, into which the protrusion 24 enters back section and 7 of the side wall 5. Thus, the insert 20 is fixed in the inserted state.

The front section 25 of the insert 20, which is included in the cavity of the front section 6, as well as the front section 6 itself, is made in the form of a hollow element, which is open at the back, with a tongue 27 cut out in the outer wall 26 of this front section, which can elastically deviate in the width direction of the door hinged element . A slightly protruding pressure portion 28 is formed on the tongue 27, which, when the insert 20 is mounted on the side wall 5 and fixed, enters the cutout 29 in the outer wall 30 of the side wall 5 and is flush with its outer surface or even slightly protrudes from it. The tongue 27 extends into the protrusion 19 and carries at its free end a supporting protrusion 31, which should enter the recess of the vertical rail of the refrigerator door and, thus, fix the hinged element to the refrigerator door. By clicking on the pressure portion 28, the user can disengage the support protrusion 31 from the door of the refrigerator and thereby disconnect the hinged element from the door. The figure 7 presents a perspective exploded view of the door leaf 40 of the refrigerator door and mounted on it a hinged door element according to the third embodiment of the invention. The door leaf 40 in a known manner comprises an inner wall which is made of plastic by deep drawing and on which two vertical rails 41 are formed. The protrusions 42 on the side surfaces of the rails 41 facing each other can normally serve to hold the door hinge made according to Figures 1 and 2. In this embodiment, there are two metal locking guides 43 that are mounted on the side surfaces of the rails 41, and the protrusions 42, covered with a locking nap railing 43, can serve as a support for the installation of the locking rails 43. On the main surfaces of the locking rails 43 facing each other, there are many locking recesses or holes 44, which can be divided vertically, essentially smaller intervals compared with the protrusions 42.

As shown in FIG. 9, the locking rails 43 are mounted on the rails 41 away from the inner surface 45 of the door 40 located between the rails 41, whereby undercuts 46 are formed on both rails 41.

As shown, in particular, in an enlarged view (figure 8), each liner 20, made according to this third embodiment, still has a hollow front section 25, which fills the cavity in the front section 6 of the side wall 5 and contains an elastic tab 27, the bearing pressure portion 28 and the support protrusion 31. The protrusion 19 of the insert 20 still has a C-shaped section with an upper and lower end surface 21, 22, each of which has a recess 23. The recesses 23 in this embodiment include locking guides 43, each supporting the second protrusion 31 is included in one of the fixing holes 44.

The free extremities of the protrusions 19 of both inserts 20, remote from section 25, enter undercuts 46. As a result, the hinged element of the door is guided by locking guides 43 with the possibility of movement vertically. To change the installation height of this element, it is enough to press the pressure sections 28 so that the support protrusions 31 come out of their fixing holes 44. After that, the entire shelf for storing refrigerated products can be moved vertically until the support protrusions 31 are fixed in another pair of fixing holes 44. Since the fixed shelf for refrigerated products cannot tip over, it can be quickly and easily rearranged in height even when loaded. To remove the shelf for refrigerated products, it must be raised above the upper ends of the locking rails 43 or lower below the lower ends of the locking rails 43 to remove the protrusions 19 from the geometric circuit with undercuts 46.

Figure 10 shows the further development of the shelf variant for refrigerated products shown in figures 8 and 9. In this embodiment, the side walls 5 have an internal wall element 50, which, without interruption, passes through the front section 6 and the rear section 7, and the outer element 30 wall, the trailing edge of which indicates the transition between the front section 6 and the rear section 7. An elongated hole 52 is cut out in the inner wall element 50. The hole 52 overlaps with the cutout 29 of the outer wall 30.

The liners 20 are made similar to the options shown in figures 7-9. They comprise a hollow front portion 25, a rearward protrusion 19 and an elastic tongue 27. In this case, the tongue 27 is bent so much that one part of it enters the hole 52 of the inner wall element. By engaging the tongue 53 and the hole 52, a locking connection can be formed which fixes the insert 20 on the main element 1.

In the idle state, as shown in section (figure 10), the inner sides of the inner wall element 50 and the portion 53 of the tongue 27 entering the hole 52 are flush. When the pressure portion 28 is pressed inwardly, the portion 53 and, together with it, the support protrusion 31 are deflected through the opening 52 into the main element 1. Therefore, the small thickness of the side walls 5 will be sufficient to provide freedom of movement of the tongue 27 necessary for fixing and releasing the support protrusion 31 .

Figure 12 shows how this principle is transferred from the door hinge to the oil container. This container can also be made with hollow side walls 5, into which the liners 20 can be inserted at the back, so that, as in the first embodiment (see Figs. 1-3), determine the appearance of the oil container or mount it on the door in a removable way .

The presented oil container comprises a hinged lid 54, the pivot axis of which extends to a certain extent in the center of the side walls 5, whereby the lid 54, passing the half-open position shown in the figure, can be moved between the closed position in which the lid 54 is essentially located flush with the front side surfaces 13 of the side walls 5, and an open position in which the lid 54 is located a short distance above the top lid 55 of the oil container. Of course, the present invention can be applied to the oil container, in which the hinged lid is installed otherwise.
