Definitions
- the invention relates to a refrigerator according to the preamble of claim 1 and a method for producing a refrigerator according to claim 9.
- the use of a photocatalytic layer such as a TiO 2 layer, is known.
- the photocatalytic coating can remove organic-chemical impurities and / or have an antibacterial effect.
- a generic refrigeration device in which the cooling space delimiting an inner wall and a plug-in tray are provided with a photocatalytic cover layer.
- a light source is arranged with which the photocatalytic cover layer can be activated in order to accelerate as a catalyst oxidation of organic deposits on the surfaces facing the cooling space.
- the refrigerator is illuminated by the light source when the refrigerator door is closed.
- such a cold room lighting can also accelerate oxidation processes for certain refrigerated goods with corresponding impairments in the refrigerated goods quality.
- the viewing window is made of glass or polymer material and serves as a light guide for exposing the photocatalytic layer to light.
- DE 10 2006 024 093 A1 discloses coating for keeping surfaces in contact with liquid media or aerosols.
- the coating has on the surface side a photocatalytic layer which is applied to a light-emitting layer.
- the object of the invention is to provide a refrigeration device or a method for producing a refrigeration device, in which the use of photocatalytic layers in the refrigerator can be done without affecting theharigut- quality.
- the photocatalytic cover layer is applied to a light guide layer over which light can be guided to the photocatalytic cover layer. According to the invention, therefore, the catalytic cover layer is not acted upon directly by the cooling chamber with light, but the cover layer is activated at its side facing away from the cooling chamber side with light.
- the molding according to the invention can be produced by way of example as a cooling chamber bounding the inner wall of the refrigerator or an insert part, such as a vegetable dish or a meat tray, in the deep-drawing process.
- the optical waveguide layer is made of a formable, in particular thermoformable material.
- the optical waveguide layer and the photocatalytic cover layer can already be advantageously connected to each other before the forming process.
- a semi-finished product designed in a two-layer structure can be provided, which can be subjected to downstream shaping, for example the deep-drawing process.
- the light guide layer may form a two-layer structure together with the photocatalytic cover layer, in which the light guide layer may be formed as a carrier layer of the molded part.
- a two-layer structure is particularly advantageous when producing an insertion part, which is usually made of transparent material, such as polystyrene or SAN, which can be used as a light guide material and at the same time is sufficiently dimensionally stable to act as a carrier layer.
- the carrier layer may have a layer thickness in the range of 1 to 6 mm, while the photocatalytic cover layer is in a range of less than 1 mm.
- the cooling space bounding the inner wall of the refrigerator can be made of polystyrene.
- the polystyrene inner wall can act as a carrier layer for the above-mentioned composite layer of optical waveguide layer and outer layer.
- the light guide layer between the polystyrene inner wall and the photocatalytic cover layer is arranged.
- the inner wall can also be made of SAN or ABS.
- the layer thickness of the light guide layer can be reduced and be in a range of 1 to 2 mm.
- the photocatalytic cover layer may comprise a photoactive material, such as TiO 2 , incorporated in a base material, such as polystyrene.
- the photoactive material can already be integrated in the plastic granules of the base material.
- the cover layer and the light guide layer preferably have the same material properties. So it is advantageous if the base material of the photocatalytic cover layer as well as the optical fiber layer is deep-drawable.
- the base material of the photocatalytic cover layer and the material of the light guide layer belong to the same families of materials or they are identical. As a result, sufficiently large laminate or binding forces can be generated between the two layers in order to avoid detachment of the cover layer from the optical waveguide layer.
- the shaping of the molded part can take place in a deep-drawing process.
- the photocatalytic cover layer can be connected to the light guide layer.
- the thus provided plate-shaped semi-finished product is then brought to a deformation temperature for a deep-drawing process and then fed to a deep-drawing device, in which the shaping of the molded part can take place.
- the photocatalytic cover layer can be coated on a carrier layer with the interposition of the light guide layer.
- the three-layer semi-finished product thus produced is then likewise fed to a deep-drawing device.
- the shaping can take place in the deep-drawing process with omission of the photocatalytic cover layer.
- the cover layer can be applied to the surface facing the cooling space only after shaping.
- Such a subsequent coating can be carried out by a per se known PVD method, by applying a corresponding liquid paint, by powder coating or by a sol-gel method.
- the subsequent coating of the already deep-drawn molded part by a subsequent plasma treatment or plasma coating with a TiC> 2 suspension or by a siloxane coating with embedded TiC> 2 - particles take place.
- Figure 1 is a schematic side sectional view of a refrigerator.
- Refrigerator arranged slide-in tray such as
- FIGS. 4 and 5 are schematic diagrams illustrating processes for the production of moldings according to the invention.
- FIG. 1 shows a side view of a refrigeration device with a cooling space 1, which is delimited by means of an inner wall 3.
- the refrigerator 1 is closed by a right in Fig. 1 appliance door 4.
- a heat insulating layer is connected in a known manner.
- the Inner wall 3 is produced in a known manner from a plastic material in the deep-drawing process.
- a slide-in tray 7 for vegetables or the like which may be made by injection molding plastic.
- FIGS. 2 and 3 The material structure of the inner wall 3 and the insertion shell 7 is shown in FIGS. 2 and 3. Accordingly, both the inner wall 3 and the insertion shell 7 on their surfaces facing the cooling chamber 1, a photocatalytic cover layer 9, which is activated by light, in particular UV light, to about organic deposits on the shell 7 and the inner wall. 3 to oxidize.
- the photocatalytic cover layer 9 is applied to a light guide layer 11.
- the light guide layer 1 1 is optically coupled via coupling points, not shown, with the light sources 13 integrated in the inner wall 3.
- the photocatalytic cover layer 9 can be acted upon on its side facing away from the cooling chamber 1 side with UV light, while the cooling chamber 1 is not exposed to UV light.
- the light sources 13 may be LEDs that emit light of a wavelength of 365 to 420 nm.
- the LEDs 13 may be integrated directly in the light guide layer 11.
- the light guide layer 11 is connected between the photocatalytic cover layer 9 and a dimensionally stable, usually colored carrier layer 15.
- the carrier layer 15 is here for example made of polystyrene having a material thickness di in the order of 4 to 5 mm.
- the middle light guide layer 11 is also made of polystyrene and has a material thickness 6 2 of about 1 to 2 mm, while the cover layer 9 has a material thickness d 3 in the order of less than 1 mm.
- the photocatalytic cover layer 9 may have as a photoactive material TiO 2 particles incorporated in a polystyrene base material.
- the cover layer 9 with the polystyrene base material, the light guide layer 11 and the support layer 15 are made of the same material, which can be achieved in a simple manner high laminate relationship or bonding forces between the layers.
- the in The material structure shown in Fig. 2 can be achieved technically simple with a three-layer extrusion.
- the insertion shell 7 according to FIG. 3 has a double layer structure.
- the optical waveguide layer 1 1 acts in a double function at the same time as a dimensionally stable
- the made of polystyrene light guide layer 11 is therefore designed in comparison to the light guide layer 1 shown in Fig. 1 1 1 with a greater thickness d 4 in the range of up to 5 mm.
- FIGS. 4 and 5 each illustrate a method for producing a molded part which can be used as inner wall 3, the material structure of which is shown in FIG. 2.
- a method step I as semifinished product, a three-layer blank section with the photocatalytic cover layer 9, the light guide layer 11 and the carrier layer 15 produced in a three-layer extrusion is provided.
- the blank part is preheated in a heating field 17 to a deformation temperature. After reaching the deformation temperature, the preheated blank part in the deep drawing step III is conveyed into a deep-drawing device 19.
- an upper deep-drawing tool 21 is thereby brought to the lower tool part 23 by pressing the blank part up to a predetermined deep-drawing gap dimension, whereby a shaping of the blank part takes place. Subsequently, the molding is removed from the thermoforming device 19.
- the photocatalytic cover layer 9 is already applied to the optical waveguide layer 1 1 in the thermoforming device 19 prior to shaping.
- the photocatalytic cover layer 9 is therefore exposed to mechanical and thermal stresses during the deep drawing process, so that a correspondingly robust embodiment of the cover layer 9 is required.
- a photocatalytic cover layer 9 is used in the process of FIG. 4, whose base material is polystyrene, in which the photoactive TiO 2 particles are introduced.
- the base material of the cover layer 9 is therefore substantially the same material with the light guide layer 1 1, whereby a large laminate adhesion between the two layers can be produced.
- the thermal or mechanical stability of the cover layer 9 through Use of the polystyrene base material sufficiently increased to subsequently achieve a damage-free shaping.
- FIG. 5 also illustrates a method for producing a molded part which can be used as inner wall 3 with a three-layer structure.
- a blank part is provided here by means of two-layer coextrusion, which here is a two-layer composite consisting of the light guide layer 1 1 and the carrier layer 15.
- the blank part is then subjected to shaping in the deep-drawing device 19.
- the photocatalytic cover layer 9 is applied to the already deep-drawn molding.
- the photocatalytic cover layer 9 can be applied by means of a PVD process which is easy to carry out by production technology, by means of liquid lacquer coating or powder lacquer coating or by means of a sol-gel process. In the subsequent coating therefore mechanical or thermal stress on the cover layer 9 can be prevented due to the deep-drawing process. Therefore, the cover layer can be applied to the inner wall 3 with a greatly reduced expenditure in terms of production technology.
