Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view of an induction heating iron set composed of one iron and one ironing board according to a preferred embodiment of the present invention. In the present embodiment, the iron is a magnetic induction coil 101 for forming an alternating magnetic field, a nonmagnetic metal 103 constituting an ironing surface of the iron, and the magnetic induction coil 101 scattered in the nonmagnetic metal 103. Heat generating metal piece 102 which is electromagnetically reacted to the heat, the movement detection sensor 104 for detecting the relative position movement between the iron and clothes 130, the temperature sensor 105 for detecting the temperature of the iron in real time, the ironing temperature Control unit 106 for setting the temperature controller 108, the movement sensor 104 and the temperature controller 108 to detect the current state of the iron to apply power to the magnetic induction coil 101, and the And a power supply unit 107 for supplying DC power to the control unit 106 and the magnetic induction coil 101. In addition, the ironing board is a clothes 130 to be ironed steam generated from the heat generated by the heat generating metal plate 111, the heat generating metal plate 111 by the electromagnetic induction coil 101 of the iron (111) To the microholes 112 for supplying to the upper side, the protective cloth 113 for protecting the garment 130, and the wood 115 and the pedestal 116 for supporting the ironing board. It is composed.

Briefly explaining the driving principle of the embodiment according to the present invention, the control unit 106 detects whether the current iron is moving from the movement sensor 104, and also detects the temperature of the current iron from the temperature sensor 105 do. Based on the detected data, the controller 106 applies AC power to the magnetic induction coil 101 only when the temperature of the iron is lower than or equal to the temperature set by the temperature controller 108 and when the current iron is moved. The magnetic induction coil 101 to which the AC power is applied forms an alternating magnetic field. The alternating magnetic field causes the exothermic metal piece 102 of the iron and the exothermic metal plate 111 of the iron plate to electromagnetically generate heat and perform ironing using them. The water 114 of the ironing board is heated by the heating metal plate 111 and generates steam. The generated steam is supplied to the garment 130 through the micro-holes 112 formed by being dispersed in the heating metal plate 111 to help ironing more smoothly. Wood 115 and pedestal 116 is to support the ironing board, the pedestal 116 is preferably made of a non-magnetic metal so as not to electromagnetically react by the alternating magnetic field. Now, the operation principle of the iron and the ironing board will be described in more detail with reference to the following drawings.

2A and 2B are partial detailed views for explaining the principle of double-sided heat generation by the iron set of FIG. Referring to FIG. 2A, the heating metal piece 22 is disposed at the lower end of the magnetic induction coil 21 installed in the iron, thereby generating heat by an alternating magnetic field generated by the magnetic induction coil 21. The metal piece 22 is heated. The reason why the heating metal piece 22 is generated is that the voltage formed on the heating metal piece 22 generates an eddy current due to an electron induction action, and the generated eddy current is an electrical resistance of the heating metal piece 22. This is because heat is generated by. The heat generated from the exothermic metal pieces 22 is conducted to the surrounding nonmagnetic metal 28 so that the entire ironing surface is heated. The magnetic flux 27 that does not pass through the heating metal piece 22 passes through the garment 23 and the protective cloth 24 to generate the heating metal plate 25 on the same principle as described above. That is, not only the iron but also the ironing board itself is heated to improve the efficiency of ironing. Here, the heating source for heating the iron and the ironing board is the magnetic induction coil 21 as described above. In addition, since the magnetic induction coil 21 forms an alternating magnetic field by applying power, the amount of heat generated by the iron and the iron board can be adjusted by controlling the power applied to the magnetic induction coil 21. 3 illustrates a configuration for controlling the amount of heat generated by the iron and the iron board by applying power to the magnetic induction coil 21.

Referring to FIG. 3, the power supply unit 35 converts general household or industrial AC power into DC in a form suitable for use with an iron, and supplies the same to the control unit 31 and the magnetic induction coil 36. The control unit 31 has three input elements: the reference temperature set by the temperature controller 34, the current iron temperature detected by the temperature sensor 32 in real time, and the current detected by the movement sensor 33. You are asked if the iron is moving. Since the temperature controller 34 and the temperature sensor 32 can be well understood by those skilled in the art and its use and implementation methods, a detailed description thereof will be omitted, and the configuration and operation of the movement detection sensor 33 will be described in detail later with reference to the drawings. Let's explain.

The control unit 31 detects an iron temperature, a reference temperature set by the user, and whether the iron is moved and switching to form an alternating magnetic field with the switching unit 37 only when the iron is moved and the current iron temperature is lower than the reference temperature. Apply a pulse signal. The switching pulse signal may have various frequencies, but in this embodiment, a frequency of 20 to 30 KHz is known that induction heating occurs best. The switching unit 37 electrically isolates the switching pulse signal output from the control unit 31 from the power applied to the control unit 31 and the magnetic induction coil 36 through photo coupling, As a result, the magnetic induction coil 36 is repeatedly switched by the switching pulse signal to form an alternating magnetic field. As described above, the condition for applying power to the magnetic induction coil 36 through a switching pulse signal is determined by the controller 31 by the temperature of the current iron and whether the iron is moved. A detailed method for determining whether the switching pulse signal is applied by the controller 31 is shown in the flowchart of FIG. 4.

Referring to FIG. 4, after applying power to the iron (step S41), the controller operated by the power source first sets the power applied to the magnetic induction coil 36 to a stand-by state ( Step S42). In this state, the user sets the ironing temperature suitable for the clothing by using the temperature controller 34 (step S43). Next, the relative position shift state between the clothes and the iron is detected (step S44). If a relative position shift occurs between the clothes and the iron, the process proceeds to the next step. If no position shift occurs, the process returns to the temperature setting step of step S44 and the iron is not heated. When the iron is moved, it is determined whether the temperature of the current iron is smaller than the temperature reference value set by the user (step S45). If the iron temperature is equal to or higher than the temperature reference value, the process returns to the temperature setting step of step S44, and the iron is not heated. If the iron temperature is lower than the temperature reference value, the control unit 31 applies a switching pulse signal to the switching unit 37 to allow a current to flow through the magnetic induction coil 36 to heat the iron and the ironing board (step S46). .

5A to 5C show the configuration and detailed operation of the movement detecting sensor 104. 5A is for explaining a schematic configuration of the movement sensor 104, the movement sensor 104 is an infrared emitter 511 for emitting infrared rays, a focus lens for condensing the infrared rays reflected from clothes ( 513, and an optical receiver 512 that receives infrared rays collected by the focus lens 513 and determines whether the iron is moved.

5B is a view for explaining the light receiving unit 512 of the movement detection sensor 104 in more detail. The infrared rays reflected by the clothes are received by the light receiving element unit 521 including a plurality of light receiving elements. Each light receiving element is amplified by the operational amplifier 522 and converted into a digitized value by the digitizer 523. The digitized value is stored in the ring counter 525 and compared in the motion sensor controller 524 with previously stored values. As a result of the comparison, if it is the same as the previous value, it is determined that there is no movement and if the values are different, it is determined that the iron is moving. A method for determining the movement state is described in FIG. 5C.

Referring to FIG. 5C, basically, the light receiving unit 512 recognizes the fabric structure of the garment. Expanding the garment being ironed has a lattice structure of warp and weft yarns. The movement sensor 104 is focused on the different type of infrared light is reflected in the presence and absence of such warp and weft, five light receiving elements each receive a reflection state of a certain area and the result of the ring counter Store at 525. If the iron moves, this reflection will change, resulting in a different electrical signal output from each receiver. For example, when the area received by the five light-receiving elements is represented as the first reception shape 531, the area a of the first reception shape 531 is not covered by the yarn while the area b is hidden. All. In this state, when the iron is moved to the same state as the second receiving shape 532, the portion a is hidden and the portion b is unobstructed, so that the signal input to the movement detection controller 524 is different from the previous signal. do. On the other hand, if there is no relative position movement between the iron and the clothes as in the third and fourth reception shapes 533 and 534, the type reflected by the fabric structure always appears the same and the motion sensor controller 524 stops the iron. It is determined that the state.

Referring to FIG. 6, the magnetic induction coil 65 is installed on an ironing board rather than an iron, and the heating metal piece 61 is installed on an ironing board, and the heating metal plate 68 is installed on an ironing board. The exothermic metal piece 61 is heated by the alternating magnetic field generated by the magnetic induction coil 65 and the exothermic metal plate 68 of the iron is heated by the magnetic flux 69 passing therebetween. The detailed heating principle is omitted because it is the same as the embodiment described above. In this case, however, it should be noted that since the power source for supplying power to the magnetic induction coil 65 is connected to the ironing board, the iron does not need to be supplied with power, so that the cumbersome power line is lost when the iron is moved.

FIG. 7 is another embodiment in which the magnetic induction coil of the ironing board according to FIG. 6 is modified, and the ironing board is not configured to form a magnetic field by one coil, but is configured such that a magnetic field is formed only at an ironed position. Referring to FIG. 7, the ironing board includes a plurality of magnetic induction coils 72 and a plurality of position switches 71 that are distributed in predetermined positions on the ironing board. The position switches 71 are normally open and are closed by the weight of the iron when the iron comes to the top. In this embodiment, the position switches 71 are formed in any position at the iron. Even if it is set to be dispersed in a predetermined position so that three or more are not closed. That is, the iron closes one or two position switches 71 at any position, and the closed position switches 71 drive adjacent magnetic induction coils 72 at their positions. The magnetic induction coil driving circuit 77 for driving the magnetic induction coil 72 adjusts the temperature according to the ironing board temperature set by the temperature control switch 74, the clothes selection switch 73, and the temperature sensor 75. After the function is performed, the time duration of driving the one position switch 71 is measured by the timer 76. When the iron is placed at one position for a predetermined time or more, the time and amount of heat stayed are calculated. Cut off the current flowing to In addition, the ironing board drives the overcurrent protection circuit 78 and the circuits 76, 77, and 78 and the magnetic induction coil 72 to prevent overcurrent from flowing through the magnetic induction coil driving circuit 77. A power supply unit 79 is provided.
