  • Patent number: 8481891
    Abstract: An ironing system (500) comprises an iron (510) with a soleplate (512) comprising an induction heatable material. The ironing system (500) further comprises a unit (520, 530) that includes at least one induction coil (540) and a device (550). The induction coil (540) charges the iron (510) whereas the device (550) detects the temperature of the soleplate (512) by sensing a change in current flowing through the induction coil (540) or by sensing a change in voltage across the induction coil (540). The current or voltage changes as self inductance of the induction coil (540) changes with magnetic permeability of the soleplate (512) as a function of its temperature. The device (550) switches the induction coil (540) on or off depending on the detected temperature.

    Abstract: A carpet seaming iron having an internal electronic temperature control circuit including a solid state temperature sensor, a power controller, and a solid state switching device is disclosed. The iron does not use a thermostat for temperature control. The iron includes a baseplate, an electrically powered heating element, a heat shield, a handle and the internally mounted control circuit. The control circuit includes a means for providing a signal to the power controller corresponding to a desired temperature of the iron. A solid state temperature sensor sends a signal to the power controller corresponding to the baseplate temperature. The power controller controls the switching device so that the amount of power supplied to the heating element is proportional to the difference between the baseplate temperature and the desired temperature. Thus as the baseplate becomes hotter, less power is supplied to the heating element, and the seaming iron maintains a stable and precise temperature.

  • Patent number: 5852279
    Abstract: A clothes iron comprises an automatic shut off system that is controlled by multiple switches. A first switch located on the iron's handle is closed when the iron is held by a user. A second switch located on the iron's heel is closed when the iron stands in the upright position. The switch on the handle prevents the automatic shut off from functioning when the iron is in use. The switch on the heel determines which of two fixed timing periods are used.

  • Patent number: 5802749
    Abstract: The recharging time for reheating the soleplate of an iron can considerably be reduced by accumulating energy from an energy supply, e.g. the mains, in a stand for the iron and by transferring this energy to the iron when the iron is attached to the stand. The iron is reheated very quickly, e.g. by exchanging cooled down liquid from the iron with hot liquid accumulated in the stand every time the iron is put back in the stand.

  • Patent number: 5391859
    Abstract: An iron comprises a heating element (97), heating-control (96) for the heating element (97), and a motion detector. The motion detector can be an electrostatic detector (35) which determines an amount of electrostatic charges present at the fabric. The motion detector can be a humidity detector (60) which detects a resistivity of the fabric between two electrodes (62.sub.a, 62.sub.b) which are in contact with the fabric. A counting circuit (89) calculates a number of halfwaves of an electric signal supplied by one of the detectors and determines whether the iron is in use or is not in use. Moreover, the degree of humidity of the fabric can be determined by a measurement circuit (99).

    Abstract: An iron comprises a heating element (97) and heating-control means (96) for the heating element. It has a humidity detector (60) which measures the degree of humidity of the fabric and which influences the electric power dissipated in the heating element. In order to measure the degree of humidity a circuit (99) measures the resistivity of the fabric between two contact electrodes (62a, 62b) and subsequently averages the electric signal resulting from the movement of the iron on the fabric. A circuit (89) may be added which measures the rhythm of the variations of said electric signal and which thus detects whether the iron is in use or not in use.

  • Patent number: 5323550
    Abstract: Thermostatic control of an electric iron is achieved through utilizing the expansion and contraction of the iron's sole plate relative to a low expansion reference member. In one embodiment, a flexible reference member extends from a fixed mounting at the tip of the sole plate to a switch unit at the rear of the sole plate. The reference number is connected to, and held in tension by, a snap acting actuator within the switch unit, such that as the sole plate expands, the free end of a blade is pulled by the reference member to cause a contact carrying tongue to snap away from a contact to interrupt the power supply. In addition, the temperature of operation may be controlled by varying the effective length of the reference member such as, for example, by deflecting it laterally by a cam member.

  • Patent number: 5120934
    Abstract: A cordless electric iron assembly has an iron removably mounted on a power supply stand adapted to be connected to a power supply. Separable mating electric terminals interposed between the iron and stand establish an electrical connection between the electric heater in the iron and the stand so long as the iron is placed on the stand. A detector on the stand detects the presence or absence of the iron on the stand and is used to activate an adjustable counter in response to removal of the iron from the stand. The counter activates an audible alarm after the elapse of a predetermined time period during which the iron is removed from the stand and in use to signal that the iron should be returned to the stand for reheating. A carrying case is detachable from the stand and accommodates the iron positioned on the stand with the mating terminals connected for storage of the iron during non-use.
