Definitions

  • the object of the present invention reveals an arrangement of elements in a heating plate and its manufacturing procedure, where the plate is constituted from conductive elements and dielectric elements, that can cover any need for heat, as whether domestic, industrial, agricultural or livestock activities, the elements that make up the plate industrially can be incorporated by a novel procedure that includes techniques such as serigraphy.
  • a heater plate generally comprises an insulated substrate in which a resistive heater track is provided.
  • a resistive heater track is provided.
  • an insulating layer of glass, ceramic or glass is provided on a metal base that has a metal plate, and the track is arranged on the insulating layer.
  • This can be achieved by joining thin resistive material to the substrate or, more generally, by using printed circuit techniques where a resistive ink is placed on the substrate or by metal spraying, for example.
  • the result of any of these techniques is a flat shape heater that can be conveniently formed, formed or joined to the base of a warming container.
  • Resistive heating tracks can also be placed on non-flat substrates, such as tubular objects or other three-dimensional objects.
  • the EP-A-0574310 document describes an example of a water heating container that has a plastic body with a printed circuit board heater that forms its base.
  • the electrical connection is made at each end of the spiral track, by wires that are attached to the track and connected to the power supply.
  • Patent FR1584094 describes a circuit deposited on an anodised aluminium substrate. But this realization in which the layer of alumina reaches only a few microns is not suitable for a circuit that works to the voltage of the electrical sector. In addition, the use is limited to lower temperatures than those of an iron sole.
  • Document EP120119 describes an aluminium substrate provided to receive a deposited electrical circuit.
  • a thick layer of anodized alumina provides electrical insulation with silicic obstructions. But if this substrate can receive an electrical or electronic circuit, there is no indication that it is adapted to withstand temperatures as high as those experienced by an iron sole.
  • Document EP058023 also describes an obstruction treatment of an anodized aluminium substrate.
  • the alumina layer is clogged with a polymerized organometallic product, for example, by heating.
  • the sealing treatment required to obtain a good dielectric resistance does not constitute a redundant safety and does not assume resistance to thermal shock that finds an iron.
  • Patent FR2763780 describes a method for manufacturing printed circuits on an aluminium substrate where a thick layer of alumina is formed on the surface to serve as insulation and can withstand high temperatures without the appearance of defects.
  • the pore blockage is not mandatory.
  • the circuit can work when the substrate is elevated at high temperature, it is specially adapted to support the implementation of integrated circuits or modules. These components, which help to cool down, do not have by far, instantaneous variations of power and temperature of an iron sole.
  • Document US3805023 describes a heating element that has an anodized aluminium substrate.
  • the alumina layer obtained in a weak acid bath is dense in contact with the substrate and is an electrical barrier, while the outer layer is porous.
  • a light sensitive product containing a precious metal was deposited which serves, after irradiation through a negative and development, as a catalyst to a chemical deposition of the nickel conducting track.
  • This present invention solves the problem in a satisfactory way, since it presents an arrangement of elements in a heating plate allowing a high performance, as well as the manufacturing process for obtaining such a plate.
  • the object of the invention consists of a heating plate constituted in turn by two elementary plates.
  • Each of the elementary plates consists of a nonconductive electric plate that serves as a resistant support.
  • the resistive component to be used is a conductive paint that offers a certain degree of resistance in such a way that the passage of the current through the painted band, dissipates energy in the form of heat achieving the desired effect: the generation of heat.
  • the electric power supply of the band painted with conductive paint is carried out by means of two metal tracks between which the conductive paint is interposed. These metallic tracks are the ones that polarize and feed the conductive paint.
  • the heating plate of the invention is composed of a facing or elemental plate composed of a nonconductive material, either mica, ceramic, glass, plastic or natural stone not electrically conductive. On it is configured a resistive circuit on its surface.
  • the circuit is consisting, of at least, three conductive tracks, formed by the projection of three metallic bands, in particular constituted by a conductive copper paste. These bands feed the resistive surface, which is achieved by painting the surface between the bands with conductive paint, on the facing of resulting product, a dielectric varnish is printed in order to encapsulate the circuit and then is dried at 450 degrees Celsius.
  • the plate arrangement (10) is configured from a facing (30) which can be rectangular, circular, square or similar, composed of a dielectric material such as mica, wood, ceramics, glass, plastics or natural stone, in such a way that it is not conductive electric.
  • a conductive paste is printed on two perpendicular conductive bands (40a) and (40b), united among themselves and arranged in such a way that the band (40a) is of greater dimensions than the length of the band (40b) and where it is also printed conductive paste on a third conductive band (60) parallel to the band (40a) and located at a distance (50) between the band (60) and the band (40b), in such a way that a rectangle of vertices is formed ABCD between of the band (40a) and the band (60). Over this rectangle surface ABCD is covered with conductive paint (20).
  • This plate can be used for the construction of a power supply electric heater.
  • the heater must have the power supply that connects to the terminals of the plate used, and also of the means of protection so that, if possible, it is not directly accessible by the user, to avoid accidents.
  • the manufacturing process of the heating plate allows a wide line of automatic serigraphy, for which, the selected meshes have been determined according to the drawing that they will make on the facing, the material to deposit, the chosen dimension, power that will develop, temperature and final destination.
  • the line is fed automatically, in the first machine, the line prints the conductive copper paste , on the facing we have chosen according to its final utility, the conductive copper paste, we will use it to introduce the electrical energy in the system, automatically it passes the oven, the paste passes through a drying oven at 450°C
  • the future heating element is reprinted, this time it is printed with conductive paint, which will be deposited the precise amount for the destination to be used, developing the precise power and temperature once finished, this conductive paint is the one that will transform the electrical energy into heat; once printed, it is transported automatically to another oven, where it is dried, cured and stabilized at 450°C.
  • the facing (heating element) is carried to a new printing machine, which will print water epoxy paint on all the surface (heating element), with the layer necessary for the heating element to be submerged in water, without leakage of electricity, then through the transfer it passes through another drying oven, which dries the paint at 150°C, once dry, the transfer deposits the heating element in the storage area, once this process is completed, the heating element is passed back through the last printing machine to print the other side with water epoxy paint, with this last step the manufacturing process is finished, either in mica plates, ceramics, crystals, plastics, etc., then come the appropriate quality checks.
  • the operational steps in the manufacturing process are:
