Abstract
A plastic-coated dish rack for a dishwasher is described, in which the residual water that is present after washing vaporizes more quickly. The dish rack comprises a wire frame made of structural steel and is coated with a plastic coating that distributes water used for washing dishes over its surface in a thin film. The plastic is for example polyamide.
Description
Dish Rack for a Dishwasher The invention relates to a dish rack for a dishwasher with a wire frame coated with plastic.
Known dishwashers on the market have at least one dish rack for arranging the goods to be rinsed. These racks are customarily manufactured as frames made of steel wire. Due to the risk of corrosion from the chemicals used in dishwashers, they are coated with an anticorrosive made of organic polymers, in which case a plastic coating, for example, is used that is usually deposited by a coating process, such as described in DE-OS 2050905. The color of the coating varies according to the design of the machine equipped with the rack.
The color is generated by adding commercial pigments to the plastic coating. Smooth surfaces are particularly preferred and are therefore generally customary, because the user assumes that no residual foreign matter will stick to these surfaces.
When the washing has finished, only drops that do not vaporize easily will therefore remain on the contact points where the washed dishes rest on the rack. The dishes therefore remain wet. It is necessary to expend vaporization energy, which affects power consumption, to vaporize these drops and dry the dishes quickly.
It is therefore an object of the invention, to create a dish rack with a surface that draws the drops of water away from the contact points by distributing them uniformly as a film across the entire coated surface, and to consequently ensure that the water will vaporize quickly with little addition of heat (residual heat). With this object in mind, the present invention provides a dish rack for a dishwasher, comprising a wire frame which is made up of structural steel and is coated wit a plastic coating that distributes water used for washing dishes over the surface in a thin film.

With this object in mind, the present invention provides a dish rack for a dishwasher, comprising a wire frame which is made up of structural steel and is coated wit a plastic coating that distributes water used for washing dishes over the surface in a thin film.
Preferably, the plastic coating has an average roughness Rz of at least 5 um and feels smooth nevertheless. A
peak-to-valley-height may be measured in accordance with DIN
4768 using the Rodenstock RM 600 laser profilometer. The measurement may be performed by scanning the surface with a laser beam. Mechanical detectors, such as the Perthometer*
M4P, display values that are too small. The average roughness Rz may more preferably be from 5 um to 100 um.
The dish rack in accordance with the invention creates, in a simple way and manner, a dish rack that ensures that the water running off the dishes, which collects as drops at the contact points between rack and dishes in conventional dish racks, will distribute itself over the rack's surface and consequently vaporize more easily.
The dish racks each consist of a wire frame coated with plastic, in which case, in accordance with the invention, the wire frame of the dish rack is manufactured of conventional structural steel and coated with a coating that distributes water in the manner described and that consists essentially of plastic, preferably polyamide, especially preferably aliphatic polyamide, such as polyamide 11 or polyamide 12, and is deposited by a plastic coating process. With the dish rack in accordance with the invention, a dishwasher rack can be manufactured in a simple way and manner and without any extra cost, that raises the overall appearance of a device and, by means of the described characteristic, ensures that the dishes will be dried without any noticeable energy expenditure.
