Definitions
- the invention relates to an iron comprising a heating element, means for controlling the heating of the heating element and a substantially flat soleplate intended to slide on a fabric.
- the ironing conditions of a fabric can be very dependent on the state of humidity of the fabric. It is indeed known that ironing a damp fabric begins with a prior step of dehumidifying the fabric.
- the electric power dissipated in the heating element can in some cases of thermostat settings be low which lengthens the duration of this dehumidification step. This results in ironing times which are abnormally long.
- the object of the invention is to provide a humidity detector for an iron which is inexpensive to manufacture industrially, an essential condition for such mass-market equipment, and which can be easily used to control the dissipated electrical power.
- the means for measuring the resistivity comprise at least one conductive terminal which is flush with the soleplate of the iron so that it can be brought into contact with the fabric.
- the electrical resistance between two terminals is measured using an appropriate assembly.
- a low value of electrical resistance is characteristic of a damp fabric.
- a high value of electrical resistance is characteristic of a dry fabric.
- the humidity detector Passing the iron over areas that have not generally not the same humidity allows the humidity detector to deliver an electrical signal which varies according to the position of the iron on the fabric.
- an average value of the electrical signal I is calculated.
- the humidity detector can thus additionally provide an indication of movement.
- FIG. 1 represents an iron 30 provided with a humidity detector 60 placed at the rear of the sole 31 of the iron.
- FIG. 2 represents a schematic view from below of an iron 30 provided with a humidity detector 60.
- the humidity detector 60 comprises two terminals 62 a , 62 b which preferably have a rounded shape, hemispherical for example , to be able to slide easily on the fabric. Terminals from 5 mm to 10 mm in diameter, for example made of stainless steel, are suitable. These terminals can be mounted on an elastic support 64 to apply well to the fabric without however leaving traces. These terminals are combined with the means which determine the average amplitude of signal I.
- the terminals are placed in housings 63 a , 63 b formed in the support 64.
- the material of the support must have sufficient temperature resistance to be brought into contact without deteriorating with more or less hot fabrics.
- FIG. 3 represents a diagram of an electrical circuit for measuring the resistivity.
- the terminals 62 a , 62 b which are in contact with the fabric 45, are connected to an electrical supply 90 and to a circuit for measuring the electrical current I passing through the circuit.
- FIG. 4 represents a curve of the variations DR of the resistance during a dehumidification operation for an iron as shown in FIG. 2.
- the humidity detector 60 encounters increasingly dry parts of fabric (over a length of iron soleplate).
- a curve A is then observed as a function of the degree s of drying. It is provided in arbitrary units.
- FIG. 5 represents a curve of variation of an output signal I as a function of the displacement d of the iron. It is representative of a signal from the humidity detector. The signal is formed by a sequence of alternations having variable amplitudes. To detect the humidity level, the average value of this signal is calculated for a determined period.
- FIG. 6 represents a circuit 99 which determines the average amplitude of the signal I (d). This average value is then representative of the degree of humidity of the fabric.
- the circuit 99 includes a resistor R1 connected to the input terminal 88 for supplying the current I. The other end of this resistor R1 is connected to an input of an amplifier 91 with high input impedance. Between the input and the output of this amplifier 91, there is arranged a circuit formed by a capacitor C d'une and a resistor R disposé in parallel. On exit 95 a signal representing the average moisture content of the fabric thus appears.
- This signal can then be used to act on the means 96 for controlling the iron to, for example, increase the electrical power dissipated in the heating element 97 to accelerate the speed of dehumidification of the fabric.
- the other entry of the amplifier 91 can be grounded.
- the soleplate of the iron can replace the terminal 62 b .
- the humidity detector then comprises a terminal 62 a and the sole 31 as a second terminal.
- FIG. 7 represents a circuit making it possible to determine the degree of humidity by measuring an average amplitude (branch 99) and to detect a use of the iron by measuring a number of alternations (branch 89).
- the branch 89 comprises a capacitor C3 and a resistor R3 connected to an input of an amplifier 92 with high input impedance to derive the signal I and supply pulses at each rising and falling edge of the signal. These pulses are then counted in a counter 93 which delivers on an output 94 a signal S when a limited number of pulses (for example 1 to 3) has appeared during a predetermined duration. This signal S is then used to act on the means 96 for controlling the iron in order to stop the heating of the heating element 97.
- a limited number of pulses for example 1 to 3
