1 to 3, the permarod heating apparatus 100 according to the present invention is surrounded by the outer frame 12 and opened upwardly in the housing 10 and the bottom surface 14 of the housing 10. Is installed on the heat insulating plate 20, the upper surface of the heat insulating plate 20, the heating plate is applied by the applied power, the plate heater 30 provided between the protective plate 32 and the surface of the heat generating plate heater 30 Heated plate 40 to be heated from the heating plate 40 is pressed in a plurality of heat transfer plate 40 so as to be directly transferred from the heated plate heater 30, the heating rod 50 is finished on the same surface as the bottom of the heat transfer plate 40 It is included.

The heating apparatus 100 according to the present invention operates simultaneously with the application of power. In one embodiment of the present invention, the power is supplied to the control block 110 through an external wire, and the control block 110 is electrically connected to the control panel 120.

The control block 110 supplies the power applied through the control of the control panel 120 to the plate heater 30 to perform heating by the electrical resistance.

In the present invention, the plate heater 30 can be handled quite selectively. For example, as shown in one embodiment of the present invention, a heating wire 34 patterned with a nickel alloy resistor having a constant width may be wound and protected by a protective plate 32 which is a sheet having excellent heat resistance. The plate heater 30 has an advantage that can be in close contact with the heating body to excellent heat response and flexibility is suitable where the precise heating is required.

Heating device 100 according to the present invention is spaced at a predetermined distance from the bottom plate 130, the control block 110 is installed. The spaced heating device 100 is sequentially stacked inside the housing 10, and the housing 10 is opened upward after being surrounded by the outer frame 12. On the other hand, where one side is sealed is the bottom surface 14 and is flat.

The heat insulation board 20 is provided in the bottom surface 14 of this housing 10. Preferably, the heat insulating plate 20 is in surface contact with the bottom surface 14 of the housing 10 to prevent the heat generation of the plate heater 30 to be transferred to the outside of the housing 10.

At this time, the side of the housing 10 is provided with a resistor 140 for protecting the heating device 100 from disconnection due to overcurrent or overheating.

The plate heater 30 described above is installed on the upper surface of the heat insulating plate 20 and is heated by an applied power source. The plate heater 30 is located between the protection plates 32 as described above, and the protection plate 32 protects the heating wire 34 which is a heating element.

The heating plate 40 is installed on the surface of the plate heater 30, the heating plate 40 is located where the user can see.

The heat transfer plate 40 is directly heated by the heating of the plate heater 30, may be made of a plate-shaped metal material for efficiency and strength of the heat transfer, and has a constant thickness.

Of course, the heat transfer plate 40 should be installed inside the housing 10, preferably inside the outer frame 12, the outer frame 12 is to define the outer portion of the heat transfer plate 40.

The plate-shaped heat transfer plate 40 is formed with a plurality of through holes 42. The through holes 42 are regularly spaced apart from each other at regular intervals. The heating rod 50 is press-fitted into the through-hole yoke 42.

Heating rod 50 is preferably finished on the same surface as the bottom of the heat transfer plate (40). By this finish, the heat transfer plate 40 presses the plate heater 30 by weight, which causes the heating rod 50 to receive the heating of the plate heater 30 directly. In addition, by artificially fastening the heat transfer plate 40 and the housing 10 described above can achieve the above object.

 In one preferred embodiment, the heating rod 50 applied to the present invention has a plurality of heat transfer holes 52 formed on the outer surface thereof, and penetrates each other.

The heat transfer hole 52 heats the air inside the heat transfer hole 52 when the heat is generated by the heat transfer, and quickly discharges the heated air. At this time, the discharged air is repeatedly circulated to heat the permarod 200 shown in FIG.

Typically, the permarod 200 is a heat pipe 210 is built in, this heat pipe 210 is heated by the heated heating rod (50).

Of course, the heating rod 50 to perform the above role in the present invention can be implemented in various modifications.

In the present invention, the temperature sensor 60 is inserted into at least one of the heating rods 50 press-fitted on the plate of the heat transfer plate 40. The temperature sensor 60 performs the sensing at 120 ℃ ~ 160 ℃, it can be set to a different temperature according to the use state.

In the present invention, the temperature sensor 60 is installed in the middle of the length of the heating rod (50). The heating rod 50 can determine the heating state of the heating rod 50 optimally. For example, the temperature sensor 60 installed on the bottom surface of the heating rod 50 or the heat transfer plate 40 is affected by the temperature of the heating rod 50 that heats the permarod 200. However, the conventionally installed temperature sensor 60 detects the temperature of the heat transfer plate 40 more sensitively than the temperature of the heating rod 50. That is, the temperature sensor 60 is normally installed because the temperature difference between the heat transfer plate 40 and the heating rod 50 is present in reality realistically, it is impossible to sense the temperature of the heating rod 50 is sophisticated.

Therefore, the present invention is installed inside the heating rod 50, more preferably, the temperature sensor 60 at the midpoint of the longitudinal direction to detect the elaborate temperature as described above and when the temperature goes out of the set temperature to short the heating rod ( 50) may be heated or radiated to maintain the permarod 200 in an optimal state.

Again, as described above, the present invention may be implemented by variously modifying the heating rod 50. Figure 4, as shown in another embodiment of the heating rod applied to the present invention, the heating rod 50 may be installed to an optimal length that can heat the permarod 200. This length is preferably between 30 mm and 40 mm, which is also economical.

The longitudinal direction used in the present invention means the vertical direction in which the heating rod 50 is installed, the center means the center point in the case of a central axis or a circle in the vertical direction.

The permarod 200 applied to the present invention is integrally formed with a heat transfer tube 210 formed in the hollow in the longitudinal center.

The heat pipe 210 may be a commonly used aluminum tube, and other metal or non-metallic material having excellent thermal conductivity may be applied.

Preferably, the heat transfer blade 212 extends in the longitudinal direction along the outer surface of the heat transfer pipe 210. have.

The heat transfer blades 212 are integrally inserted into the body of the permarod 200 made of synthetic resin.

Due to this structure, the heating temperature transferred to the heat transfer pipe 210 is transmitted to the body of Permarod 200 without loss, and can maintain a constant temperature even in use.

Preferably, the heat transfer blades 212 are formed in a plurality in a shape symmetrical with each other at the center of the concentric circles of the heat transfer pipe 210.

With this structure, the heat transfer blades 212 can faithfully perform heat transfer, and at the same time, can also perform a role of thermal insulation, and reinforce the strength of the main body due to the plurality of heat transfer blades 212.

And through the heating device 100 and permarod 200 as described above can provide a fast, excellent thermal insulation, economical perm device.

In the present invention, it goes without saying that various other modifications are possible. For example, as shown in FIG. 7, the outer surface may be inclined and formed as a heating rod 50 finished with a flat upper surface as necessary. The interior of the permarod 200 is inserted into the heating rod 50 is formed in a shape corresponding to each other while forming an inclined surface with the heating rod 50.

As shown, the heating rod 50 and the permarod 200 inserted therein are fixed to each other by an inclined surface, and may conduct heat transfer through the inclined surface.

Since the inclined surface is in direct contact with the permarod 200 can maximize the efficiency of the heat transfer, it is possible to perform a quick heat transfer, it is economical because the material is saved by a relatively short heating rod (50). In addition, as shown in FIGS. 8 and 9, a separate heat transfer button 300 is installed at the bottom of the permarod 200 and inserted into the heating rod 50 of the conical shape as described above to transfer heat to the permarod 200. It can be done efficiently. As shown, the heat transfer button 300 is composed of a fixed frame 310 is installed between the lower outer surface and the inner surface of the permarod 200 and the inclined frame 320 that receives the heat transfer from the heating rod 50 directly have.

The center of the inclined frame 320 is penetrated and has a constant elastic force. This elastic force is in close contact with the inclined surface of the heating rod 50 serves to fix the heating rod (50). That is, the heating rod 50 and the inclined frame 320 by the elastic force is in close contact with each other to perform rapid heat transfer, and does not deviate from the present invention. Accordingly, all modifications existing within the true spirit and scope of the present invention are included in the claims.
