Abstract

A door shelf (1, 1', 1") for a refrigeration appliance, in particular a household refrigeration appliance, has the shape of a box that is open at the top and that has a front wall (2) made of plastics which faces away from the door when the door shelf is mounted to the door. The surface of the front wall (2) is roughened up in a first portion (13, 15) and is smooth in a second portion (14, 16).

Description

Refrigerating appliance and door rack with roughened area for it

The present invention relates to a refrigeration device, in particular a household refrigeration device such as a refrigerator, and an inner container for mounting on the inside of a door of such a refrigerator.

Refrigeration appliances are manufactured by many manufacturers in different model series, which differ from each other in the valence of their design and the costs of - in particular for the design of the visible surfaces - used materials. In order to produce such different model series cost-effective, it is desirable to use as many identical parts in refrigerators of different model series. The ability to use the same parts, however, is limited by the requirement that the model rows in their optical

Clearly differentiate appearance and thus just those parts that are visible to the user, should differ from one model series to another. The use of different, one for each

Series specific door compartments is a common way to visually differentiate different model series. In order to limit the cost of different types of door housings, it has been proposed to use multi-part constructed door racks in which a model series across unitary base is combined with different decorative elements on its front wall, and the decorative elements depending on the model from each other by shape, choice of material or may differ. However, such a necessarily multi-part construction makes the manufacture of the door racks complex and leads to increased costs, which affect the economics of manufacturing, especially in low-cost model series.

The object of the invention is therefore to provide a concept that allows refrigerators in several model rows with different optical design with minimal

Expenditure, especially for devices of inexpensive model series to provide.

The object is achieved on the one hand by a door rack for a refrigerator, in particular a household refrigerator, in the form of an open-topped box with a in the mounted on a door state facing away from the door, made of plastic front wall and two side walls, wherein the surface of the front wall and / or the side walls roughened in a first region and is smooth in a second region.

The first roughened area is preferably in the upper area of

Front wall and / or side walls. In this case, the first area is then the upper area. But it can also be arranged below. This is useful, for example, if the box is a butter compartment in which the front wall can be opened or pushed away. However, the first area can also be in the middle, so that it crosses the second area, for example, and divides it into two areas.

The roughened area can be located on the inside of the door racks or preferably on the outside.

Such a door rack is complete and usable on its own, and the division into the upper and lower areas already results in a clearly visible attractive design without the use of additional decorative elements, so that the door rack in a

Refrigeration unit of a low-cost series without additional components can be used and thus causes minimal costs. Particularly noteworthy is the subdivision in roughened first and smooth second area, if the plastic used is clear, so that the second area is transparent, the first, however, while transparent (translucent), but is opaque. Preferably, the plastic used is colorless or light, especially transparent, preferably crystal clear, or tinted green or bluish. In the roughened area, the transparent plastic looks opaque. The second area is smooth, preferably shiny.

The front wall should be integrally formed at least with a bottom plate and / or side walls of the door compartment; Preferably, the complete door rack is integrally molded from the plastic.

In order to increase the conspicuity of the design, and possibly also to increase the stiffness of the front wall, the first and the second area may be separated by a step. For models with higher design standards, which can be marketed at higher prices and accordingly more design effort can be operated, the upper area may be coated with a coating. Such a coating, while opaque, hides the underlying roughened surface

Surface, but allows in exchange extensive other

Design options such as the use of different colors, metallic surfaces or the like.

Such a coating may be printed, in particular by screen, pad or inkjet printing.

It is particularly preferred to use a hot stamping foil as the coating.

By a surface roughness of less than 20 μηη, preferably less than 15 μηη, even more preferably 10 μηη or less, however, it is possible to apply a hot stamping foil here without any disadvantages.

Preferably, the roughened surface has a fine-grained structure, preferably an irregular structure, more preferably a structure in the range MT 1 1 xxx, (where x may be an integer between 0 and 9); particularly preferred with the designation MT 1 1000.

In an inventive texture of the surface, it is possible to have a

Apply hot stamping foil to a roughened area without the structure of the surface interfering with the appearance of the hot stamping foil.

The generation of the surface roughness and the structure preferably takes place in a manner known per se by tool-bonded erosion. The coating can also extend to the side walls of the door compartment, in particular on their visible in the mounted state on the door areas. According to another embodiment, the upper area can be covered by a decorative profile in the case of a door rack designed for a more complex model series. Such a decorative profile is preferably latched to a step of the front wall, in particular to the aforementioned, extending between smooth lower and rough upper portion of the front wall stage.

The extent of the decorative profile may be limited to the front wall, but it may also be part of a frame extending over the side walls and rear wall of the door frame, depending on the embodiment, both a one-piece component and a physically detached from the rest of the frame and attached to this Component.

Such a decorative profile can be mounted as a bar or as a circumferential or on one side open frame on the upper portion of the door compartment or on the lower portion of a butter compartment. The decorative profile preferably has the same

Surface roughness as indicated for the door rack and then can

advantageously also be coated with a hot stamping foil.

In order to minimize the manufacturing costs of the door compartment, it makes sense that its side walls are single-layered. Such single-layer sidewalls can each carry an inverted U-shaped rib for anchoring the door compartment to a refrigerator door, so that in the surrounded by the rib, downwardly open recess can engage a support projection, which emanates from a molded on the inside of the door spar. The object is further achieved by a refrigeration device, in particular a

Domestic refrigerating appliance having a door rack as described above.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Fig. 1 is a perspective view of an elementary door compartment according to the present invention; Figure 2 is a cross-section through the front wall and part of the bottom plate of the elementary door compartment of Figure 1;

Door compartment according to a fourth embodiment; and

Fig. 6 shows a schematic section through a refrigerator with a door rack according to the invention.

Fig. 1 shows a perspective view of an elementary door racks 1 according to a first embodiment of the invention. The door racks 1 integrally formed from a clear plastic material essentially has the shape of a box open at its top, with a front wall 2, a rear wall 3 and side walls 4, which are each separated by a vertically extending step 5 into a front and a rear part 6, 7 are structured. The front part 6 is exposed when the door rack 1

is intended to be mounted on a refrigerator door 8 (see FIG. 6) of conventional design; the rear part 7 is provided to be concealed in the assembled state of mutually facing flanks of integrally formed on an inner side of the door 8 spars 9, and each has a rib 10 in the form of an inverted U, which in the mounted state on the spars 9 integrally formed support projection 1 1 receives. All the walls 2, 3, 4 of the door compartment 1 are each single-layered, free of internal cavities, shaped, so that a simple design, inexpensive mold for manufacturing the elementary door compartment 1 can be used.

The front wall 2 and the front parts 6 of the side walls 4 are divided by a horizontally extending step 12 into first (here upper) and second (here lower) regions 13, 14 and 15, 16, respectively. Those surfaces of the mold, which are the lower ones

Areas 14, 16 form, are polished smooth, so that the surfaces of the areas 14, 16 at Outside and inside of the walls 2, 4 level and accordingly the areas 14, 16 are transparent clear. Of the upper surfaces 13, 15 forming surfaces of the mold at least one roughened by erosion, preferably that which forms the outside of the regions 13, 15. If the surface roughness of the regions 13, 15 is several μηη, preferably about 10 μηη, the upper regions 13, 15 no longer appear as the bottom crystal clear and glossy, but milky cloudy and dull. Therefore, although the elementary door racks 1 are made in one piece of a single material and with a single mold, surface areas are obtained that differ significantly in their appearance.

Fig. 2 shows a vertical section through the front wall 2 and a part of an adjoining bottom plate 17 of the door compartment. 1 Here, the upper area 13 is slightly cantilevered over the lower area 14 by the step 12, so that the areas 13, 14 are not only different from each other in appearance, but are also marked clearly three-dimensionally by the step 12. At the

Inside the upper portion 13, a shallow undercut 18 is formed, so that the thickness of the front wall 2 in spite of the step 12 in both areas 13, 14 in

Essentially the same. FIG. 3 shows a second embodiment of a door compartment according to the invention in a section analogous to FIG. 2. Since this door rack is no longer designed in a strictly one-piece design, it is referred to here as a complex door rack V in order to distinguish it from the elementary door rack 1 which is contained in it. On the upper regions 13, 15 of the front and side walls 2, 4 a coating 19 is applied in each case nationwide. It may be a - preferably opaque - dye layer, which is applied for example by ink jet screen or pad printing. In the case of FIG. 3, the coating is a hot stamping foil with a decorative layer 20 and an underlying hot melt layer 21, which is melted in contact with the elemental door racks 1, so that it fills the unevenness of the roughened upper regions 13, 15 and for a flat , durable adhesion of the

Decorative layer 20 on the elementary door racks 1 provides. The coating 19 ends in Fig. 3 each exactly at the top and bottom of the upper portion 13. A variant, it could also on the horizontal upper edge of the front wall, possibly also over the shoulder 12, extend to the door rack V a massive Appearance, similar to that described below with reference to FIG. 4 embodiment.

Depending on the desired appearance of the complex door compartment V, the decorative layer 20 can consist of various materials, for example it can be a pigmented plastic film, a metal foil or a thin laminate

Metal layer and the metal from corrosion and abrasion protective top layer of transparent, possibly colored colored plastic act.

4 shows a complex door racks 1 "according to a third embodiment of the invention in a section analogous to FIG. 2. At least the upper area 13 of the front wall 2, preferably also the upper areas 15 of the side walls 4, is here a decorative profile 22 with inverted U-shaped cross-section, with an outer leg 24, an inner leg 25 and a resting on the upper edge of the front wall 2 connecting piece 26 between the legs 24,25, plugged and held by frictional engagement or, preferably, by positive locking Embodiment of Fig. 4, the positive locking is achieved by a

Latch 23 on the lower edge of the outer leg 24 of the decorative profile 22, which engages behind the horizontal step 12 on the outside of the front wall 2. Alternatively, a locking lug on the inner leg 25 could be provided in the

Undercut 18 engages; in this case, the lower edge of the outer could

Leg 24 should be exactly flush with the level 12.

Thus, despite the small wall thickness of the outer leg 24 can not be permanently bent easily readily, the decorative profile 22 should be one piece extended to the front parts 6 of the side walls 4. The decorative profile 22 can each end at the vertical steps 5; A preferred development shown in exploded view in FIG. 5 results in only the outer limbs 24 of the decorative profile 22 ending at the steps 5, whereas the inner limbs 25 and the connecting section 26 also extend beyond the rear parts 7 the side walls and the rear wall 3 extend and so the upper edges of the

Door cabinet 1 completely overlapping frame form, giving the impression that the door rack 1 in its entire upper part of a different material than in the lower. 6 shows in a schematic section the door rack 1 according to one of the embodiments described above in a household refrigerator 27. This includes in a customary manner a body 28 and the door 8, which together define a cooling compartment 28, in which the suspended on the door 8 Door racks 1 protrudes. The door 8 has a molded plastic one-piece inside 29, on the adjacent to its lateral edges two into the interior of the refrigerator compartment 28 projecting spaces 9 are formed. One of these spaces 9 is visible in Fig. 6 and carries on its side facing the other space flank formed support projections 1 1, one of which is hidden behind the door rack 1 suspended therefrom.
