Description

Description: TECHNICAL FIELD The present invention relates to an ironing device using an electromagnetic induction heating device.

2. Description of the Related Art A conventional iron has been configured such that a heater connected to a power cord is buried in the iron body and ironing is performed by heat generated by the iron body. However, there has been a drawback that the working position is restricted by the positional relationship of the power cord. Recently, cordless irons using heat storage materials have also been developed to solve this drawback.However, there is a problem that the temperature of the iron body drops during ironing, so it is possible to generate heat even during ironing. There is a demand for a cordless iron.

In order to solve these problems, an electromagnetic induction heating ironing device has been proposed. As shown in FIG. 2, the electromagnetic induction heating type ironing apparatus includes an induction heating coil and an inverter circuit for applying a high-frequency current to the induction heating coil inside an iron table 32 having a plurality of legs 31. An electromagnetic induction heating device 33 is provided, and an ironing surface 34 made of cloth or the like is formed on the upper portion of the electromagnetic induction heating device 33. A power cord 36 having a plug 35 attached thereto is connected to a power supply circuit 39 of the electromagnetic induction heating device 33. When power is supplied to the electromagnetic induction heating device 33 through the power cord 36 and the power supply circuit 39, the induction heating coil Generates a high frequency magnetic field. 37 is an iron base that is made of a magnetic material such as iron or is made of a magnetic material itself, and a handle 38 made of a non-magnetic material is attached to the upper part of the iron base, and the iron body is placed on an iron table Only in this case, the iron base 37 is heated and the ironing operation can be performed. According to this electromagnetic induction heating type ironing device, the power cord is not provided on the iron main body, so that the ironing work becomes easy, and the iron main body is constantly heated during the ironing work. There is no problem that the temperature of the iron body drops.

Problems to be Solved by the Invention By the way, in recent irons, steam is generated from an iron body at the time of ironing, and wrinkles of clothes are stretched by the water content. It is also generally known that ironing performance is enhanced by passing steam through clothing.

However, in the above-described electromagnetic induction heating type ironing apparatus, since the induction heating coil and the inverter circuit are disposed immediately below the ironing surface 34 through which steam passes, when steam is generated from the iron body,
Water droplets adhere to the induction heating coil, the inverter circuit, and the like, resulting in insulation failure and the like, which is not practical. In order to solve this problem, when the ironing surface is made impervious to steam, there is a drawback that steam does not pass through clothing and ironing cannot be performed well.

Means for Solving the Problems In order to solve the above problems, the present invention has an iron body having a magnetic layer formed at least at a lower portion and having a steam generator inside, and a space between an ironing surface and a top plate. An electromagnetic induction heating coil provided on the lower surface of the top plate, a circuit for applying a high-frequency current to the electromagnetic induction heating coil, and an iron table having an exhaust fan in the space are provided.

Operation According to the above configuration, the magnetic layer provided at the lower portion of the iron body is heated by the high-frequency magnetic field generated from the electromagnetic induction heating coil provided on the iron table, whereby the wrinkles of clothes on the iron table are extended. When steam is generated from the iron body at the time of ironing, the steam passes through the clothes on the ironing table, then passes through the ironing surface to reach the space, and is exhausted by the exhaust fan provided in the space. Is discharged. Therefore, the electromagnetic induction heating coil and the circuit are protected from steam by the top plate. Further, since an ironing surface in a state where steam is easily removed can be adopted, good ironing can be easily performed.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of an electromagnetic induction heating type ironing apparatus showing one embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an iron main body, and an iron base 2 having a magnetic layer formed on at least a lower surface is provided below the iron main body. On the iron base 2, a heat insulating case 3 that does not allow the heat of the iron base 2 to pass through is mounted by screws, and further, a water tank 4 is provided on the front side and a handle 5 is provided on the rear side by screws. It is attached by. A steam generator 6 is provided on the iron base 2, and the steam generator 6 is supplied with water from the water tank 4 through a nozzle 7 communicating the water tank 4 and the steam generator 6 to generate steam. .

11 is an iron table, 12 is an ironing surface made of felt, cloth, etc. provided on the upper surface of the iron table, and this ironing surface 12 is on a top plate 13 made of an insulating material such as resin or ceramic. And is supported by a peripheral portion of a top plate 13 extending upward. 15 is an electromagnetic induction heating coil formed of litz wire,
A plurality of screws are fixed to the lower surface of the top plate 13 via a coil base 16 on which the electromagnetic induction heating coil 15 is mounted. A ferrite rod 17 is adhered to the lower surface of the coil base 16 to prevent the magnetic force from the electromagnetic induction heating coil 15 from leaking downward. A circuit board 18 for applying a high-frequency current to the electromagnetic induction heating coil 15 is fixed on a bottom surface of a lower case 19 forming a lower part of the ironing table 11 via a screw 20 and a power cord having a power plug 21 attached to a tip thereof. 30
Is connected. A concave portion 14a communicating with the space portion 14 at the center position of the top plate 13 is formed by a casing 22 integrally formed with the top plate 13, and an exhaust fan 23 is provided in the concave portion 14a.
Is arranged. This exhaust fan 23 has a casing
The motor 22 is mounted on a rotating shaft 24 rotatably supported by the motor 22 and is rotated by a fan motor 25 mounted on the lower surface of the casing 22. The casing 22 is provided with an exhaust port 26 communicating with the outside of the ironing table, while an appropriate port on the side surface of the top plate 13 is provided with an intake port 27 for communicating the space 14 with the outside. The passing steam and air from the intake port 27 are forcibly discharged to the outside through the exhaust port 26 by the exhaust fan 23. 28 is a leg formed integrally with the lower case 19, 29 is a front leg fixed to the lower case,
The front legs 29 prevent the ironing table 11 from tilting even when ironing is performed at the end of the ironing table 11.

With the above configuration, when ironing,
When the power plug 21 is inserted into a power outlet (not shown), an object (eg, clothing) to be ironed is placed on the ironing surface 12, and the iron body 1 is pressed on the iron base 2. Is heated by a high-frequency magnetic field generated from the electromagnetic induction heating coil 15, and as a result, the temperature is increased and a known ironing operation is performed.

When steam is used, after the steam generated from the iron body 1 passes through the body, passes through the ironing surface 12 and enters the space 14, and is discharged into the atmosphere by the exhaust fan 23 through the exhaust port 26. Is discharged. Therefore, steam is not applied to the electromagnetic induction heating coil 15 and the circuit board 18, and good ironing can be performed.

Effects of the Invention As described above, according to the present invention, when steam is used, steam generated from the iron body passes through the clothes, reaches the space through the ironing surface, and is discharged to the external space by the exhaust fan. Therefore, it is possible to provide an iron table in which the steam does not hit the electromagnetic induction heating coil or the circuit and the steam is easily removed, and ironing can be performed easily and easily.
