Definitions

  • the present invention relates to a method for arranging an electrical or electronic component on a refrigerator and/or freezer.
  • plastic-coated cables with a single- or multi-core combination of metal cores are usually used to supply electrical power to consumers in refrigerators and/or freezers or for signal transmission. These are attached to the components of the refrigerator using brackets, clips or adhesive tape, especially on the foam side in the case of foamed insulation.
  • Individual sensors or heating elements are also attached to the designated locations using suitable fastening options and are then electrically supplied by cables and/or connected to appropriate cables for signal transmission.
  • a conceivable case of error is if, after assembly of the cables or other components, the assembly space, i.e. the space between the inner container and the housing of the device, is filled with foam, such as polyurethane foam, for insulation purposes and then an electrical fault caused by incorrect assembly or by the foaming Contacting is detected.
  • foam such as polyurethane foam
  • heaters to avoid condensation formation such as so-called frame heaters
  • frame heaters are often carried out by pipes connected to the compressor circuit on the pressure side.
  • These pipes have a high degree of geometric complexity and can only be produced with considerable effort and can only be transported efficiently and damage-free to a limited extent or with great effort. Additional damage can occur during processing, causing functional defects to occur with great frequency.
  • the direct integration in the compressor circuit does not allow any regulation Heating function, which affects the system's function and efficiency. Apart from that, pipes for heating have poor contact.
  • the present invention is based on the object of simplifying the arrangement of electrical or electronic components in refrigerators and/or freezers.
  • the arrangement is carried out by thermally spraying a material onto a substrate of the refrigerator and/or freezer.
  • the arrangement takes place by thermally spraying the electrical or electronic component or a part thereof onto a substrate of the refrigerator and/or freezer.
  • the component is a line for conducting electricity and/or for transmitting data and/or a heater, preferably a frame heater and/or a sensor and/or an intelligent component, in particular is a control or regulation unit.
  • the component is preferably a heating element or a sensor or a circuit board or a circuit, for example for regulation or control.
  • heating elements or sensors by thermal spraying also leads to advantages in terms of function, efficiency and safety.
  • targeted energy input can be achieved through optimal coupling to relevant positions depending on local requirements.
  • Arranging heating elements or sensors or the like by thermal spraying also leads to cost advantages, since metal frame heaters, such as refrigerant pipes, or glued-on heating elements can be omitted.
  • the foam flow of, for example, polyurethane foams in areas to be foamed is improved, since electrical cables and/or electrical components applied by thermal spraying lie flatter on the corresponding walls than cables or finished components and the foam can therefore flow better over them.
  • the refrigerator and/or freezer can, on the one hand, perform its basic function, which is to provide a cold storage space, but also in terms of the design or lighting or other intelligent functions, for example through multiple sensors or multiple actuators in all conceivable places on the refrigerator and/or freezer can be optimized while at the same time eliminating cables and pipes that prevent recycling.
  • the material before thermal spraying is a powder, preferably with a grain size of D50, in particular with a particle size between 5 ⁇ m and 50 ⁇ m, preferably between 30 ⁇ m and 50 ⁇ m.
  • the material before thermal spraying can also be referred to as the starting material.
  • the material has zinc, tin, copper or aluminum or alloys made from these materials and/or that the material is a polymer made conductive.
  • the material is arranged in layers, whereby the composition of the material can differ in layers. Material with the same composition can also be arranged in layers.
  • the layer structure of the conductive elements or material preferably depends on adhesion, required conductivity and contacting technology.
  • the layer thickness preferably depends on the function to be fulfilled, such as heating, cables or sensors.
  • the electrical resistance of the material or the component is preferably approximately 50% ⁇ 20% of the bulk material.
  • the bulk material is preferably the electrically conductive material in the material.
  • the arrangement is carried out automatically, preferably by a robot.
  • the arrangement can also be done manually.
  • the component of the refrigerator and/or freezer is an inner container or a motor niche or a thermoformed or deep-drawn 2D or 3D component of the refrigerator and/or freezer.
  • components or substrates such as inner containers, motor niches or thermoformed 2D or 3D components of refrigerators and/or freezers
  • passages through walls, for example for wiring are reduced in size or become unnecessary, which reduces or prevents Foam escapes during foaming.
  • cables are prevented from appearing on visible surfaces of the refrigerator and/or freezer.
  • the substrate is the inner container of the refrigerator and/or freezer, the substrate being formed by the side of the inner container facing the cooled interior and/or by the side of the inner container facing the thermal insulation.
  • the arrangement is carried out by atmospheric pressure cold plasma spraying.
  • another thermal spraying process is also possible.
  • the electrically conductive layers or components applied to the components of refrigerators and/or freezers by thermal spraying are electrically insulated from the environment and from other electrically conductive components.
  • an electrical insulation in particular a polymer layer or an inorganic, non-conductive layer, is applied to the material, in particular by means of thermal spraying, plasma, painting or lamination.
  • the electrical insulation which is electrically non-conductive, can also be referred to as an insulating cover layer.
  • the thickness of the insulation or cover layer preferably depends on the necessary insulating properties.
  • the substrate is preferably electrically insulating or provided with an electrically insulating layer.
  • the invention also relates to a refrigerator and/or freezer with an electrical or electronic component, the component being arranged using a method according to the invention.
  • plastic-coated cables or pipes or the like can be largely or completely eliminated. This means that the foam is no longer contaminated with jacket materials or the like and can therefore be recycled more easily.
  • Thermal spraying of materials makes it possible to apply any electrical and/or electronic functions to geometrically complex components of a refrigerator and/or freezer in a reproducible, cost-efficient and high-quality manner.
  • Thermal spraying of electrical cables and/or electrical components onto components of refrigerators and/or freezers also creates degrees of freedom in the attachment of electrical elements and a high level of flexibility in the routing of electrical cables.
  • the component has a porous, metallic structure, with the porosity preferably being between 1% and 10%, in particular between 5% and 10%.
  • the electrical and/or electronic components are preferably arranged on an inner container or on a motor niche or on a thermoformed component or on a panel or on a door or on a coated sheet of the refrigerator and/or freezer.
  • Thermal spraying offers the following advantages, particularly compared to additive manufacturing technology.
  • the component in particular the electrically conductive structure, is generated by depositing conductive, preferably metallic, powders, which have significantly lower material costs compared to conductive inks and pastes.
  • the process temperatures of the method according to the invention can preferably be adapted to the substrate.
  • this preferably enables the direct coating of high impact polystyrene (HIPS), even with the wall thickness of an inner container that is common in refrigerators and/or freezers.
  • HIPS high impact polystyrene
  • contact points By arranging the material in layers, contact points can be equipped with copper layers to enable soldering processes.
  • a three-layer structure consisting of substrate, component or electrical conductor and insulating cover layer is provided in order to create electrically conductive structures on 3D substrates of a refrigerator and/or freezer, such as inner containers or side walls.
  • the electrically conductive layer is preferably characterized by a porous metallic structure in the conductor cross section.
  • Thermal spraying is not an additive manufacturing process, but rather a surface coating process.
  • DIN EN 657 defines the classification of thermal spray processes.
  • thermal spraying according to DIN EN 657 with kinetic energy as cold gas spraying; by beam as laser spraying; from melt as melt pool spraying; with gaseous or liquid fuels as detonation spraying, high-speed flame spraying or as flame spraying with powder, wire or high-speed wire; can be carried out by electrical gas discharge as arc spraying or as plasma spraying in the atmosphere (atmospheric pressure cold plasma spraying), in vacuum, under inert gas, under excess pressure or by induction.
  • the exemplary embodiment relates to an inner container made of plastic of a freezer or one of the side walls made of sheet metal, onto which electrically conductive layers are applied or arranged using the method according to the invention.
  • the electrically conductive layers consist of thermoplastics made electrically conductive by adding electrically conductive additives
  • the electrically conductive layers are electrically insulated by a further application of electrically non-conductive thermoplastic. Since the inner container is made of electrically non-conductive plastic, the conductive layers are completely surrounded by insulating material.
  • Heating elements are also applied to the inner container using the method according to the invention and electrically insulated by a further application of electrically non-conductive thermoplastic.
  • the heating elements are preferably applied by atmospheric pressure cold plasma spraying Fig.1 .
  • the order is carried out on a device, the device comprising a holder for the inner container and a robot.
  • the holder holds the inner container, for example, in such a way that the concave, i.e. the side of the inner container that is cooled during operation, can be placed over a receptacle, which fixes the inner container in space and makes the foam side of the inner container easily accessible to a robot.
  • the inner container can also be fixed by clamps or jaws or other clamping or fastening means.
  • sensors on the holder such as air gap sensors, which check whether the inner container is correctly seated. The correct fit can also be checked visually.
  • the robot follows its programmed path and the device attached to the robot synchronously applies the respective material to the inner container using thermal spraying.
  • the inner container can be applied to the holder in an automation line by another robot or another conveyor or manually and removed from it again using these methods after the application.
  • Another advantage of the invention is that no corrosion of heating pipes can occur.
