Description
- This invention relates to a heating device for heating a body, for example the sole of an electric iron, comprising electrical heating means for said sole, a temperature sensor for sensing the temperature of said sole and a regulating circuit for keeping said sole at a required bias temperature.
- Such a device is known from DE- 1 299 089, wherein the heating means are received between the sole and a cover and either the thermosensor is a bimetallic strip or the 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 to the body 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 of the body being able to occur as a result of too slow a regulation. With the heating device according to the invention it is in addition possible when the body cools to immediataly regulate the supply of heat to it.
- To this end the heating device according to the invention is characterized in that at least partly ceramic material is chosen as material for said sole, the temperature sensor is a thermistor and said thermistor and said heating means are embedded in said ceramic sole.
- The thermistor can only be applied on a non-conductive surface and this is achieved by the sole partly being of ceramic material.
- Further characteristics and details of the heating device according to the invention will become apparent with reference to a drawing, in which:
- figure 1 shows a perspective, partly broken away top view of a heating device according to the invention arranged on a ceramic part of a body,
- figure 2 shows a diagram of the heating device in figure 1,
- figure 3 shows a perspective, partly broken away top view of another embodiment of a heating device according to the invention, in which the body is a sole of an iron,
- figure 4 is a diagram of the heating device as according to figure 3,
- figure 5 shows an exploded perspective top view of another embodiment of a heating device according to the invention, and
- figure 6 shows an exploded, perspective top view of yet another embodiment of the heating device according to the invention, in which a plurality of independently controllable heating means is embedded in a body.
- In a ceramic.
layer 15 of a body, in the form of a plate 2 provided with a temperature sensor 4, whichlayer 15 is formed for example by an enamelled metal plate 16, there is embedded a heating device 1 according to the invention, for example using thick film technique, this heating device 1 comprising electrical heating means 3 in the form ofresistance paths 7 connected between two conductingstrips 17 and a thermistor 6 in the form of a thermo path 32 (figure 1). Both theresistance paths 7 and one ormore 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. - In figure 2 can be seen schematically a regulating circuit 5 in which a
resistance path 7, using a power supply source connected betweenterminals member 20. Theresistance path 7 consists for example of screen-printed resistance paste having a low coefficient of resistance; thethermo 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 regulatingmember 20 is activated by an electrical signal originating from anoperational amplifier 10, this electrical signal being a measure for the value of the temperature dependent resistance ofthermo path 32 relative to theadjustable resistor 21 which is coupled to a thermostat knob (not shown). Theoperational amplifier 10 is biased by thebias resistors thermo path 32 as well asresistance path 7 are crenellated in form, and in a way such thatthermo path 32 is located in the vicinity ofresistance path 7 so that regulation of the temperature takes place quickly. - In another embodiment of the heating device according to the invention (figure 3) plate 2 is formed by a metal sole 12 of an unshown iron provided with an
enamel layer 15. For a still quicker reaction to temperature changes of the underside of the sole 12, which can cool off rapidly during the ironing of for example a wet sheet, 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 conductingpaste 8 and provided with an enamel layer 24 onto regulating circuit 5. - The advantage of these lower thermo paths 6' is that they are located on the ironing surface of the
metal plate 25 having a large heat capacity, so that the supply of heat tometal 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 usingresistors - The regulating
members - In another embodiment df the heating device according to the invention (figure 5), using the same screen-print pattern, electrical heating means 3 in the form of
resistance paths 7 arranged between conductingstrips 17 as well as a thermistor 6 in the form ofthermo paths 32 arranged between conductingstrips 33 can be applied onto a metal plate 16 provided with anenamel layer 15, with anintermediate 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. - Another embodiment of heating device 1 according to the invention (figure 6) 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 toplate 34 can be regulated. At eachsurface 35 are arranged an embeddedresistance path 7 and athermo 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. By means of a central key board, connected with control members 14 and secured on aframe 37, and associated electronics (not shown), the temperature of thesurfaces 35 can be adjusted and measured, and these temperature values can be read on adisplay panel 38.
