Definitions

  • This invention relates to a heating device for according to the precharacterizing for example the sole of an electric iron, part of claim 1.
  • thermosensor is received there­in as well.
  • the drawback of this known heating device is that the heating means and the thermosensor are spaced from the sole and that therefor the regulating of the heat supply to the sole is relatively slow.
  • the invention has for its purpose to provide a heating device which includes a temperature sensor displaying a highly reduced delay and which enables a continuous regulation of the heat supply without causing delay therein, which makes it possible to operate the electrical heating means with a greater power, for example 3,000 instead of 1,000 watts, without overheating being able to occur as a result of too slow a regulation.
  • a heating device which includes a temperature sensor displaying a highly reduced delay and which enables a continuous regulation of the heat supply without causing delay therein, which makes it possible to operate the electrical heating means with a greater power, for example 3,000 instead of 1,000 watts, without overheating being able to occur as a result of too slow a regulation.
  • the heating device according to the invention is characterized according to claim 1.
  • the thermistor can only be applied on a non-conductive surface and this is achieved by the sole partly being of ceramic material.
  • thermo path 32 (figure 1). Both the resistance paths 7 and one or more thermo paths 32 are preferably crenellated or meander shaped to increase their length.
  • a resistance path can however also take a rectangular form in order to obtain the greatest possible power transfer to the plate 2; the power transfer per surface is in any case bound to a maximum because of the properties of the enamel layer.
  • thermo path 7 consists for example of screen-printed resistance paste having a low coefficient of resistance
  • thermo path 32 consists for example of NTC or PTC paste having a high temperature coefficient.
  • the pastes from the 7600/7700 Du Pont range are suitable for this purpose.
  • the regulating member 20 is activated by an electrical signal originating from an operational amplifier 10, this electrical signal being a measure for the value of the temperature dependent resistance of thermo path 32 relative to the adjustable resistor 21 which is coupled to a thermostat knob (not shown).
  • the operational amplifier 10 is biased by the bias resistors 22 and 23.
  • thermo path 32 as well as resistance path 7 are crenellated in form, and in a way such that thermo path 32 is located in the vicinity of resistance path 7 so that regulation of the temperature takes place quickly.
  • plate 2 is formed by a metal sole 12 of an unshown iron provided with an enamel layer 15.
  • sole 12 is provided on both sides with NTC or PTC thermo paths, whereby the non-visible lower thermo paths 6 ⁇ can be connected via holes filled with conducting paste 8 and provided with an enamel layer 24 onto regulating circuit 5.
  • thermo paths 6 ⁇ are located on the ironing surface of the metal plate 25 having a large heat capacity, so that the supply of heat to metal plate 25 has already got under way before a considerable discharge of heat through the insulating enamel layer to the object to be ironed from the metal plate takes place.
  • the supply of current to electrical heating means 3 is regulated by a regulating member 11 which is controlled by electrical signals originating from two operational amplifiers 26, 27 (figure 4).
  • Amplifiers 26, 27 are biased using resistors 28, 29 and 30 and using an adjustable resistor 31 connected onto an unshown thermostat knob, and amplify the temperature dependent resistance changes of respectively the lower thermo paths 6 ⁇ and the resistors 6.
  • the regulating members 10 and 11 can for example be standard PID regulators suitable for one or two inputs.
  • thermo paths 7 in the form of resistance paths 7 arranged between conducting strips 17 as well as a thermistor 6 in the form of thermo paths 32 arranged between conducting strips 33 can be applied onto a metal plate 16 provided with an enamel layer 15, with an intermediate insulating layer 13.
  • Either the heating means 3 or thermistor 6 can hereby be embedded in the enamel layer, on the upper as well as on the lower part of for example a sole of an iron.
  • heating device 1 is applied in so-called spot heating for manufacturing semi-conductor elements, whereby, by regulating the temperature of a plate 34 accurately from point to point, the viscosity and thereby the thickness of semi-conductor material (not shown) to be applied to plate 34 can be regulated.
  • a plate 34 At each surface 35 are arranged an embedded resistance path 7 and a thermo path 32 using which the temperature of such a small surface can be accurately controlled with the aid of a control member 14 arranged at each surface.
  • a central key board connected with control members 14 and secured on a frame 37, and associated electronics (not shown), the temperature of the surfaces 35 can be adjusted and measured, and these temperature values can be read on a dislay panel 38.
