Definitions

  • This invention patent specification particularly refers to a new resistive element, built from an absolutely innovative formal structure, notably developed to be applied to hair drying heating equipment and other similar equipment that require heat to use, said resistive element including innovative formal features that provide, in practice, higher efficiency in utilization as well as increased power savings, belonging specially to the field of ohmic resistance heating devices and components, heating elements including a surface that essentially extend across two dimensions, for example, heating plates, heating elements structurally combined to coupling elements or to supports, hair drying devices and accessories, electrically heated air production devices, handheld drying devices, for example, air dryers or similar equipment.
  • Said resistive element may be used in equipment that require a certain amount of heat to be generated and maintained inside said equipment, either for air heating, in the case of hair dryers, or for heating ceramic plates, in the case of hair straightening devices or any other similar uses that require using a high performance resistive element capable of heating and maintaining a high temperature for use.
  • the current state of the art comprises modern equipment that feature resistive elements, which are, as a rule, shaped through usually linear filaments, with said resistive element models failing to achieve proper performance and, therefore, having their utility restricted, as they fail to provide the required efficiency in heating and maintaining heat inside the equipment, and having greatly reduced useful life due to this fact.
  • Hair dryers and other equipment that function based on a heating principle normally feature electric resistances which, when heated, provide, through heat exchange effects, heating of the airflow that circles through said resistances.
  • electric resistances are usually mounted onto a support structure, around which the helical body that defines electric resistance must be properly placed and fixed.
  • the electric resistances of the state of the art feature a helical and malleable physical constitution, which requires use of specific machines and equipment for handling and installation.
  • said resistances may also be assembled manually, which proves to be time-consuming and increases respective operational cost, thus increasing the final cost to the customer.
  • Another objective of THIS invention patent application refers to the manufacturing process of said resistive element, said process being particularly used in powering the embodiment of the resistive element, object of this patent application.
  • resistive element applied to heating equipment is to enable the dimensions of said on the same construction platform of standard resistances, built in helical shape, to reach ideal working temperature, depending on the equipment, with at least a 35% reduction in power consumption.
  • Another objective of the present patent application is to provide a device including a flat resistive element, which features a shaping pattern that maximizes the area of contact with the fluid media to be heated (air, in the case of hair dryers and similar equipment).
  • Said resistive element is mounted on an insulating material structure, combined with internal ducts for concentrated direction of the heat flow.
  • the flat profile resistive element is produced through a stretching or wire drawing process in a flat profile tool, intended for use as replacement to standard helical-shaped electric resistances, either in hair dryers and similar equipment, or other types of heating equipment, the flat profile resistive element may be produced from conductor sections of various shapes, as a "blank" from a strip or coil made of a material alloy that features a known resistive coefficient.
  • Hair dryers and other equipment that function based on a heating principle normally feature electric resistances which, when heated, provide, through heat exchange effects, heating of the airflow that circles through said resistances.
  • this invention patent application concerning a resistive element applied to heating equipment features a resistive element 1 of a flat and aligned profile assembled in a wave-shaped format 2, in which a certain number of support structure units 3, each including four radial vanes, is mounted and able to be used in a hair dryer model SC or any other similar equipment, considering that said support structure 3 receives, as well as the units of the resistive element 1, the respective connection terminals and a thermostat, in addition to electrical wires required to power the resistive elements 1.
  • the resistive element 1 is mounted on stamped support structures 3 radially placed with each other, featuring, for this purpose, four vanes manufactured in demicanite or other insulating material with similar characteristics.
  • the resistive element 1 with a flat profile and wave-shaped alignment 2 features a substantially higher efficiency regarding conventional resistances.
  • the flat profile resistive element 1 when used, for example, in a hair dryer SC powered with a standard 127 or 220 V voltage, generates around 1300W in power due to the cold airflow FAF passing in between the resistive elements 1 of a hair dryer SC, for example, which is optimized due to its laminar wave-shaped format 2, receiving cold air FAF and delivering, therefore, an amount of hot air in the form of a hot airflow FAQ that is higher and more efficient, with less power consumption.
  • the resistive element 1, object of this invention patent application when applied to a hair dryer SC, for example, and when set up in its maximum combination of temperature and airflow, provides around 35% in power savings if compared to the power of other devices comprised in the state of the art which, on the other hand, often require generating between 2100 and 2200 watts of power to be able to deliver the same work temperature.
  • the low power consumed by the flat profile resistive element 1 is harnessed much more efficiently, in face of the higher concentrated heat generation, resulting from the wave-shaped format 2 of said profile.
  • the resistive value of the flat profile is significantly higher, providing less power consumption and comparable work temperature to the other versions comprised in the state of the art, that feature a higher power consumption.
  • the U or V wave-shaped format 2 may be obtained through specific forming machinery, enabling relatively accurate sizes and widespread repeatability.
  • the flat profile resistive element 1 is obtained via a metal alloy strip 4 with a previously known resistive coefficient.
  • the flat profile and wave-shaped 2 resistive element 1 is not limited to this format, considering that the setting described herein was specifically developed for use in hair dryers SC, and while it does not constitute a limiting factor to the use of the resistive element 1 for this type of embodiment, other shape configurations may be demanded, provided the main characteristics of this resistive element 1 are respected, namely flexibility, placement onto a support structure manufactured in demicanite or other insulating material of equivalent features, and laminar shape structure.
  • the amount of units/waves 2 or resistive element units 1 may vary to a greater or lesser extent, depending on the technical requirements of its specific embodiment.
