Definitions

  • the invention relates to a system comprising an object and a heating device for heating the object and more in particular to a temperature control of the heating device.
  • heating devices such as electric stoves have a thermal efficiency lower than 50%.
  • An object to be heated must be in a close contact with the heating device.
  • Such heating devices can realize temperature control by a rough estimation or via a temperature sensor that is coupled to the heating device. If the object moves away for a while from the heating device during operation, contact between the object and the heating device is lost. In such cases, the temperature of the object will be out of control as temperature control is based on detecting the temperature of the heating device.
  • an induction heating technology which is a non-contact and non- thermal energy transfer technology with very high thermal efficiency, i.e., about 90%, is introduced to get rid of the required contact between the object and the heating device.
  • a conventional induction heating device normally needs a piece of ceramic resting plate, which is a good thermal conductor, for supporting the object to be heate d up by the induction heating device.
  • the temperature of the object is monitored by a temperature sensor placed under the ceramic plate.
  • the temperature sensor is a thermistor, a thermocouple, an NTC or a thermal diode.
  • the disadvantage of such temperature control is that the object must be in contact with the ceramic plate where temperature sensors are installed. So it does not give a true non-contact solution. It will also result in a lag in sensing the temperature.
  • the special ceramic material is expensive and supply of it is limited.
  • the accuracy in sensing the temperature will still be influenced by proper contact and thermal conduction.
  • the sensors must sense the hot surface directly and cannot be covered or insulated, and hence may not be safe.
  • US4268737 describes an apparatus in which a cordless flat iron is energized by one or more high-frequency oscillators subjacent the normally horizontal work supporting surface of an associated ironing board.
  • the sole plate of the iron consists of a thin layer of conductive material and is electrically and thermally insulated from the handle of the flat iron.
  • the magnetic field, of a polarity alternating at high frequency, which is generated above the work supporting surface by the oscillator generates eddy currents in the sole plate when the flat iron is placed on the surface or separated from the surface by normally nonconductive textile material to be ironed.
  • a temperature sensor on the iron senses the temperature of the sole plate, and a wireless transmitter transmits a temperature signal, based on the sensed temperature, from the iron to the receiver on the ironing board and this signal is compared to the pre- set temperature.
  • the induction heating coils are turned on/off based on the temperature signal transmitted. Since this involves transmission of information regarding the temperature, it requires expensive components.
  • a system comprising an object including a temperature control device, a transmitter and a power source, wherein the temperature control device is arranged for sensing the temperature of the object and activating the power source, and the power source in turn is configured for activating the trans mitter for transmitting a wireless signal, depending on the sensed temperature; and comprising a heating device including a receiver and a switching circuit, wherein the heating device is configured for heating the object, the receiver is configured for receiving the wireless signal, and the switching circuit is configured for activating the heating device, based on receipt of the wireless signal.
  • the temperature control device is in series with the transmitter and lets or does not let the transmitter transmit its signal, depending on the sensed temperature.
  • the temperature control device uses inexpensive elements to detect the temperature of the object. When the temperature of the object is lower than a desired temperature, it indicates a "1" /"high” state wherein the heating device is turned on. However, when the temperature of the object exceeds the desired temperature, it interrupts the wireless signal and indicates a "0" /"low” state wherein the heating device is turned off.
  • the temperature control de vice could use a simple mechanical control to control the transmittance of the signal. The presence or absence of this signal indicates whether the object needs to be heated or not. This is only a signal transmission rather than an information transmission. It is a binary logic and uses simple components and signal processing.
  • the temperature control provides reakime temperature control, firm and uninterrupted linkage between the heating device and the object as well as a user-friendly and safe design.
  • the temperature control device comprises a temperature setting element configured for setting a pre-determined temperature to which the object has to be heated; a sensing element configured for sensing the temperature of the object; and a switching element configured for activating the power source when the sensed temperature is below the pre-determined temperature, with the power source being configured to activate the transmitter for transmitting a wireless signal to the heating device.
  • the temperature setting element is used to input the pre-determined temperature and works together with the sensing element to provide a controllable temperature setting.
  • the switching element activates the power source whenthe sensed temperature of the object is below the pre-determined temperature. Only then the power source activates the transmitter to send the signal to the receiver of the heating device and the heating device is turned on. On the other hand, when the temperature of the object equals or exceeds the pre-determined temperature, the switching element deactivates the power source which in turn deactivates the transmitter and interrupts the wireless signal, and the heating device is turned off.
  • the temperature control device along with the transmitter and the power source forms a simple electrical circuit unit. It provides wireless linkage/communication between the object and the heating device by transferring temperature information about the object in the form of a signal that is detected by a temperature sensing element and regulated by a temperature setting element.
  • the sensing element is a mechanical thermostat or a thermocouple, a thermal diode, a thermistor, an infrared sensor or the like.
  • the sensing element is provided with multiple sensing points for sensing the temperature of the object at multiple positions. This is because the object may not be made of pure material and also its configuration may not be uniform. Heat transfer from points of heating to points of sensing may cause a lag in sensing the temperature. Therefore, more sensing points are provided which rectify the final temperature reading, depending on analysis of the overall temperature distribution.
  • a thermal fuse is connected to the object, said thermal fuse being configured for deactivating the power source when the tempeiature control device fails.
  • a thermal fuse which does not depend on any control or feedback process, is indispensable. This is because temperature control could fail for any unpredictable reason. If the heated object is overheated, the thermal fuse will be blown to cut off the power source and thus stop the system from working.
  • the wireless signal is transmitted to the heating device by a carrier wave.
  • the carrier wave is an electromagnetic wave, a light wave, a sound wave and the like
  • the electromagnetic wave B a radio frequency wave and the like
  • the light wave is an infrared wave, a laser wave and the like
  • the sound wave is an ultrasonic wave and the like.
  • the power source is a dry cell or alkaline battery. It can also be a Lithium- ion, Nickel-Cadmium, Nickel- metal hydride battery.
  • the switching element cuts off the battery while the system is not in use and hence the battery will not drain.
  • the power required by the transmitter to emit the signal is very low. Hence the battery will last for several years.
  • the object is provided with an auto shut off feature, which auto shut off feature is configured for ensuring the safety of the heating device.
  • the heating device is in the form of (an) induction coil(s), halogen lamps, conventional tubular heating elements and the like.
  • the above-mentioned temperature control works for any kind of heating device.
  • the object is configured to be heated while moving or while stationary. While in use, the object may move away from the heating device. The wireless signal transmitted from the transmitter ensures that the temperature of the object is controlled even when the object is away from the heating device.
  • the object is an iron and the heating device is one or more induction coil(s).
  • the iron has a soleplate that is heated by electromagnetic radiation from the induction coil. Due to the dynamics of the iron during ironing, it is difficult to control the temperature of the iron. The wireless signal ensures that the temperature of the iron is under control.

  • the battery 230 works efficiently, it can keep the safety battery /super-capacitor fully charged. When the battery 230 fails, the safety battery or the super-capacitor provides energy immediately.

  • the rechargeable battery can be charged in three different ways.
  • the first charging means is a simple cord charger, like any charger of a portable device, which has an additional adapter.

Abstract

Un système comprend un objet comportant un dispositif de commande de température, un émetteur et une source d'alimentation. Le dispositif de commande de température détecte la température de l'objet et active la source d'alimentation. La source d'alimentation active à son tour l'émetteur destiné à émettre un signal hertzien, en fonction de la température détectée. Le système comprend en outre un dispositif de chauffage comportant un récepteur et un circuit de commutation. Le dispositif de chauffage est configuré pour chauffer l'objet. Le récepteur reçoit le signal hertzien émis par l'objet, et le circuit de commutation active le dispositif de chauffage, sur la base du signal hertzien reçu. Ce système permet uniquement de transmettre un signal au récepteur du dispositif de chauffage pour décider si l'objet nécessite d'être chauffé ou non.
