Referring to the effect of the rod-shaped heating type induction heater of the present invention having such a configuration as follows.

First, the rod-type heating type induction heater to which the present invention is applied, as shown in FIGS. 1 to 6 (a) and (b), a hollow rectangular enclosure type body 2 and a plurality of guide plates 3 and a pipe type. The main technical components include a working coil 4, an insulated and insulated coil fixture 5, a plurality of heating plates 6, an inverter 7 and an operation unit 8.

At this time, the rectangular enclosure type body 2 is opened, the front and rear, and the upper surface is provided with an inverter housing 23 that can accommodate the inverter 7 as well as to protect the user from high heat in the front opening. A safety net 21 is installed in order to provide a rear plate 22 at the rear opening, and in particular, each of the bottom four corners is stopped in order to smoothly move the induction heater itself to which the present invention including the main body 2 is applied. It has a structure in which a wheel 24 provided with a sphere, that is, a caster is provided.

Of course, the volume of the main body 2 is determined in correspondence with the heating output (for example 5 ~ 7 kW) of the induction heater to which the present invention is applied, and may be molded into a desired volume through press working using a general iron plate. In addition to the rectangular housing described above, it may be molded into a cabinet or the like.

On the other hand, in the case of forming the back plate 22 provided on the back of the main body 2 using an iron plate or the like as the material of the main body, a part of the heat generated from the heated plate 6 to be described later is the back plate. There is a fear that it is discharged to the rear side of the main body 2 via the 22.

Therefore, in the present invention, part of the heat generated from the heated plate 6 is formed by molding the back plate 22 detachably installed in the back opening of the main body 2 by gypsum or heat resistant plastic having low thermal conductivity. Can be prevented to some extent from being discharged to the rear side of the main body 2 via the back plate 22.

In addition, in the present invention, by further installing a heat reflecting plate 10 formed of a metal material having a good heat reflectance on the inner surface of the back plate 22 is generated from the heated plate 6, the rear of the main body 2 The heat transmitted to the heat reflecting plate 10 can be reflected back to the front opening side of the main body 2, so that the heat dissipation efficiency of the heating plate 6 and the heat reflection efficiency of the heater itself can be greatly improved.

The plurality of guide plates 3 may be formed of a ceramic-based heat insulator so as to have a rectangular plate shape having a height corresponding to the height of the inner space of the main body 2, and a plurality of pairs of " ⊂ "type working coil fixing groove 31 and the" C "type plate to be fixed hole 32 has a form formed at a predetermined interval.

The guide plate 3 having such a configuration electrically insulates the pipe-type working coil 4 and the plate to be heated 6 and blocks the heat of the plate to be heated 6 and also pipe-type walking coil 4. Insulation function is performed so as not to be transmitted to the side.

At this time, the number of the guide plate 3 is installed at a predetermined interval in the horizontal direction according to the horizontal length of the pipe-type working coil (4) whose length is determined corresponding to the heating output of the induction heater to which the present invention is applied is determined Usually, one is installed in each of the inner side of both sides of the main body 2, and one or more of one to three may be selectively installed between the two guide plates 3 corresponding to the heating output.

In addition, the distance between the " 형 " type working coil fixing groove 31 and the " C " type heating plate fixing hole 32 formed to form a pair in the horizontal direction at the rear portion of the guide plate 3 is the present invention. This design is different from each other according to the heating output of the applied induction heater. For example, assuming that the heating output is 5 ~ 7 kW, any one distance (i.e. Molding may be performed so as to have a sufficient distance so as not to be electrically shorted.

On the other hand, the pipe-type working coil (4) is assuming that the heating output of the induction heater to which the present invention is applied, for example, 5 ~ 7 kW, thickness (t) is 1 ~ 2mm and diameter (Φ) 10 Bending and molding a copper or aluminum pipe of ˜15 mm in a zigzag form, and then detachably attaches to the working coil fixing groove 31 of the guide plate 3 using a plurality of insulated and insulated coil fasteners 5 described later. In a fixed installation, when a high frequency current output from the inverter 7 flows, it generates a magnetic field having a predetermined induction heating frequency (X ㎑) to perform the function of induction heating the heated plates 6 to 400 to 600 ° C. .

As described above, in the present invention, a disconnection failure is caused by using the pipe-shaped walking coils 4 formed by zigzag using copper or aluminum pipes as described above, without forming the coils into bundles like the working coils used in general induction equipment. It is possible to extend the life of the product itself as well as to reduce the cost of maintenance.

In addition, the insulated and insulated coil fixture 5 is pipe-shaped in a state in which it is coupled in a form surrounding the outer surface of the pipe-shaped walking coil 4 fitted in the working coil fixing groove 31 of the guide plate 3. The pipe-type walking coil 4 includes a pipe-type working coil 4 and a guide plate 3 and is fixedly installed in the working coil fixing groove 31 of the guide plate 3 together with the working coil 4. And to perform a function to electrically insulate between the heating plate 6 to be described later, as well as to perform a heat insulating function to block the heat.

At this time, the insulation and insulation coil fixture (5) is very good insulation and insulation, and when combined with each other by using a light ceramic (Ceramic), Mullite (alu) or alumina (Al ₂ O ₃ ) "O" ring shape Molded in the form of a pair of "C" ring to have a, but by forming a flow preventing groove 51 along the outer circumferential surface center line coupled to form a wrap around the outer surface of the pipe-type walking coil (4) the pipe-type walking coil A part of the guide plate 3 exposed to the working coil fixing groove 31 when the fixing coil 31 is installed in the working coil fixing groove 31 of the guide plate 3 together with the insulation coil insulation Inserted into the flow preventing groove 51 of the (5) is the state in which the insulated and insulating coil fixture (5) itself is fixed in the working coil fixing groove 31 of the guide plate (3) without flowing horizontally Will be maintained.

On the other hand, in the above, in the state in which a pair of insulated and insulated coil fasteners 5 are coupled to the outer circumferential surface of the pipe-type working coil 4, respectively, the "⊂" type working coil fixing groove 31 of the guide plate 3 is simply ), The pipe-type working coil 4 and the insulated and insulated coil fasteners 5 are guided by the "⊂" -type working coil fixing groove 31 of the guide plate 3 by an external impact or the like. There is a risk of leaving outward through the opening.

Accordingly, in the present invention, the pipe-type working coil 4 may be fixed even if any impact force is applied by externally installing the fixing bracket 9 in the vertical direction at the rear end surface of the guide plate 3 using a screw. Insulating and insulating coil fixture (5), including through the "⊂" type of the working coil fixing groove 31 of the guide plate 3 is maintained without being completely fixed.

At this time, the fixing bracket 9 may be formed in a plurality of short lengths and installed one for each opening of the plurality of “⊂” type working coil fixing grooves 31 formed in the guide plate 3 as shown in FIG. To form a length substantially corresponding to the length of the guide plate 3, as shown in Figs. 1 to 4 and 6 (b) a plurality of "⊂" type working coil fixing groove 31 openings as one fixing bracket It may be installed so that (9) can be integrally prevented.

In addition, the plurality of heating plate 6 is heated plate fixing hole 32 formed at a predetermined distance to the front portion of the working coil fixing groove 31 in the guide plate 3 using a non-magnetic magnesium alloy or the like (32). Bent to correspond to the shape of the zigzag and bent into the heating plate fixing hole 32 of the heating plate of the guide plate 3 so as to cover a part of the linear part of the pipe-shaped walking coil (4) The plate to be heated 6 is inductively heated to 400-600 ° C. by a magnetic field generated when current flows in the pipe-shaped walking coil 4 to perform a function of heating ambient air.

At this time, the arc length of the heated plate fixing hole 32, which is formed in the heated plate 3 and the guide plate 3, each of which has a longitudinal "C" shape, is generated in the pipe-type working coil 4, respectively. In order for the magnetic field to be sufficiently transmitted to the heated plate 6 and to allow the heated plate 6 to generate sufficient heat at a desired temperature, the outer circumferential surface of the pipe-shaped working coil 4 may be at least 1/2 or more to 2/3. It is desirable to mold to surround the.

 In addition, the magnesium alloy, which is a non-magnetic material used in the production of the plate to be heated 6, has a heat diffusion coefficient of 1.4 [cm 2 / sec], a thermal conductivity of 60 to 90 [W / mK], and a density of 1.8 ± 0.3. [g / cm3], melting temperature is 595 [℃], specific heat is 1.02 ~ 1.05 [J / gK], and heat emission is 2.5 ~ 3 times better than ferromagnetic materials such as cast iron or steel, and its density is low. The induction heater itself is light in weight, the invention is very portable and portable, as well as good heat dissipation, heating efficiency is also very good.

In addition, when the heating plate 6 is simply formed into a "C" -shaped plate shape, the heat dissipation area is limited, so in the present invention, if necessary, either one or both of the front and rear surfaces of the heating plate 6 are required. By protruding a plurality of heat dissipation protrusions 61 at predetermined intervals, the heat dissipation area of the heated plate 6 itself can be widened as much as possible, thereby further improving heat dissipation efficiency.

In addition, the inverter 7 is provided in an inverter accommodating portion 23 provided above the main body 2 to provide a predetermined induction heating frequency band X ㎑ necessary for driving the pipe-type walking coil 4. It is to perform the function of generating a high frequency current.

At this time, the predetermined induction heating frequency band (X ㎑) generated in the pipe-shaped walking coil (4) may vary depending on the material of the plate to be heated (6), generally induction when using a ferromagnetic material such as cast iron, steel While the heating frequency is set to a band of 5 to 15 [KHz], in the present invention, the induction heating frequency band is set to 40 to 100 [Hz] by molding the heated plate 6 with a non-magnetic magnesium alloy as described above. ] Can be designed in such a way that the output frequency of the inverter 7 for driving the pipe-type walking coil 4 is raised more than twice.

In addition, the operation unit 8 includes a heating temperature setting key, an on / off switch, and the like, and is installed on the upper or upper surface of the main body 1 so that the user can input various operation signals required for driving the induction heater. To perform the function.

As described above, the induction heater of the present invention heats the surrounding air through a method in which a magnetic field generated when a current flows in the pipe-type working coil 4 induces a heating plate 6 to heat the fluid of the heater itself. It is very light and easy to install and use, and it does not consume any oxygen in the room during operation of the heater, and it does not generate various harmful gases or odors, so it is harmless to the human body and of course, it can maintain the indoor environment comfortably. In addition, the induction heating method itself has a heat conversion efficiency of 85-95% compared to the used power, which is very economical because the power use efficiency is higher than other heaters, and the product can be manufactured at low cost, thereby reducing the economic burden on the consumer. .

On the other hand, the guide plate 3 and the insulated and insulated coil fixture 5 are electrically insulating as shown in FIG. 6 (a), so that the guide plate 3 has a plurality of pipe-type walking coils 4 and Even if the heating plate 6 is fixedly installed at a predetermined distance, there is no big problem in the insulation between the pipe-type working coil 4 and the plate 6, but if the pipe-type working coil 4 or the plate to be heated 6 If some part is bent, there may be a short circuit and induction heating itself may not occur, and an electric safety accident may occur.

Therefore, in the present invention, the high-temperature insulation and the insulating tube 11 woven with ceramic or glass fiber on the outer surface of the pipe-type walking coil 4 as needed to cover the form as shown in (b) of FIG. Insulation between the pipe-shaped working coil 4 and the plate to be heated 6 can be performed completely.

In addition, according to the present invention, by providing one or two blower fans 12 at the rear of the pipe-type working coil 4 as necessary, the heat may be generated by the heating plate 6.
