Specific features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

In FIG. 2, the present invention electrode dryer is provided with a cylindrical outer cylinder 11, one end of the outer cylinder 11 is hinged with a hinge pin 12, the auxiliary lid 14 is coupled to the other end. .

An inner cylinder 15 is provided inside the outer cylinder 11, and a heat insulating material 16 is provided between the outer cylinder 11 and the inner cylinder 15, and the pull tab 17 allows the welding rod to be taken out inside the inner cylinder 15. Is provided.

A heating coil 20 is wound around the outer circumferential surface of the inner cylinder 15, and an insulating terminal 24 made of a ceramic material is fixed to the end of the inner cylinder 15 by a coupling bolt 23. ), One end of the connecting line 21 connected to the heating coil 20 is supported.

In addition, a temperature controller 30 is installed at one side of the outer cylinder 11, and the temperature controller 30 and the power supply line 22 are fixed to the insulating terminal 24 and connected to the connection line 21. The outer cylinder 11 on one side of the regulator 30 is provided with a lamp 25, which is also connected to the connection line 21 of the insulating terminal 24.

On the other hand, the temperature controller 30 is installed between the power line 22 and the heating coil 20 as described above to adjust the heating temperature of the inner cylinder 15 and to maintain the set temperature constant, which is shown in FIG. It has a configuration as shown in Figs.

The temperature controller 30 has a knob 31 having a plurality of scales printed on its outer circumference and a bolt shaft 32 on its bottom, and the bolt shaft 32 being raised and lowered when the knob 31 is rotated. A nut 33 coupled to the shaft 32 and an insulating terminal 34 to which the nut 33 is embedded are provided.

And one side is fixed to the insulating terminal 34, the other side is elastically supported to the upper side and the elastic bracket 36 is provided with a pressing protrusion 37 at the other end, and the elastic bracket 36 to face the lower end of the bolt shaft (32) Bellows 41 is fixed on the) and the oil is stored therein, the temperature sensor 43 is in close contact with the outer peripheral surface of the inner cylinder 15, the oil is stored therein and connected to the bellows 41 by the oil pipe 42 Is provided.

In addition, the on / off switch 40 connected to the power line 22 and the heating coil 20 is provided below the insulating terminal 34, which is the push projection 37 of the elastic bracket 36 toward the lower side. When the elastic piece 38 and the fixing piece 39 are transported, they are turned off, and the pressing protrusion 37 is transferred upward, so that the elastic piece 38 and the fixing piece 39 are on when the elastic piece 38 and the fixing piece 39 come into contact with each other. It is.

Reference numeral 19 is a handle and 18 is a support leg.

The inventive electrode dryer of this configuration rotates the knob 31 of the temperature controller 30 to heat the inner cylinder 15 to an appropriate temperature, and rotates the knob 31 counterclockwise so that the inner cylinder 15 is rotated. When the temperature is lowered, as shown in FIG. 5, the bolt shaft 32 is lowered to press the upper portion of the bellows 41 to press and support the elastic bracket 36 downward, and thus the push protrusion 37 is lowered to support the upper side. It is separated from the elastic piece 38 of the on / off switch 40, and the elastic piece is spaced apart from the fixing piece 39 while being restored to the lower side as shown in FIG. The on / off switch 40 is turned off and the lamp 25 is turned off.

As such, when the on / off switch 40 is turned off, the power supply to the heating coil 20 is cut off, and thus the inner cylinder 15 is no longer heated, and the temperature gradually decreases.

When the temperature of the inner cylinder 15 is lowered, the oil inside the temperature sensor 43 which has been expanded while the temperature of the temperature sensor 43 installed in close contact with the inner cylinder 15 is lowered together with the inner cylinder 15 is contracted. The oil inside 41 is introduced into the temperature sensor 43 through the oil pipe 42.

As the oil in the bellows 41 flows into the temperature sensor 43, the bellows 41 is contracted, so that the elastic bracket 36 is elastically supported downward by the bellows 41. It is restored to the upper side by the contracted height of the, as the pressing projection 37 is raised by the height of the resilient bracket 36 is elastically supporting the elastic piece 38 to the upper side to the elastic piece 38 and the fixing piece 39 ) To turn on / off the switch 40, the lamp 25 is turned on.

As such, when the on / off switch 40 is turned on and the heating coil 20 is heated, the temperature of the inner cylinder 15 is increased, and when the inner cylinder 15 is raised above a predetermined temperature, the temperature sensor (which is in close contact with the inner cylinder 15) As the 43 is heated, the oil inside the temperature sensor 43 expands, and the expanded oil flows into the bellows 41 through the oil pipe 42, thereby expanding the bellows 41.

Therefore, as the bellows 41 is expanded, the elastic bracket 36 is pushed downward, and accordingly, the pressing projection 37 is transferred downward, so that the elastic piece 38 is restored downward, so that the elastic piece 38 and the fixed piece are lowered. 39 is spaced apart from each other so that the on / off switch 40 is turned off.

In this way, the inner cylinder 15 always maintains the temperature controlled by the knob 31.

On the other hand, to set the inner cylinder 15 to be heated to a high temperature, the knob 31 is rotated clockwise to raise the bolt shaft 32.

As shown in FIG. 3, when the bolt shaft 32 is raised, the elastic bracket 36 is restored upward, and the bellows 41 and the elastic bracket 36 supported at the end of the bolt shaft 32 are raised. Likewise, the pressing protrusion 37 presses the elastic piece 38 upward to contact the fixing piece 39, thereby turning on the on / off switch 40.

As such, the inner cylinder 15 set to be heated to a high temperature is continuously heated by the heating coil 20 as time elapses. As the inner cylinder 15 is heated above a proper temperature, the expansion force in the temperature sensor 43 is increased. As the oil expands, the oil expands into the bellows 41 through the oil pipe 42 and expands it, and the elastic bracket 36 is pressed downward while the bellows 41 expands. The switch 40 is turned off.

This electrode design dryer can adjust the degree of heating of the inner cylinder 15 by the temperature controller 30, it is possible to always maintain a constant temperature when the appropriate temperature is set.

In addition, since the connecting line 21 and the power supply line 22 connected to the heating coil 20 are connected to each other after being fixed to the insulating terminal 24, the insulating terminal 24 of the ceramic material is heated even when the inner cylinder 15 is heated to generate heat. It is not affected at all, and thus the connection portion of the power supply line 22 and the connection line 21 embedded and connected to the insulation terminal 24 is not affected at all.

According to the welding rod dryer according to the present invention as described above, the inner cylinder 15 is heated because the power supply line 22 and the connection line 21 are fixed to the insulation terminal 24 of the heat-resistant porcelain material and connected thereto. Even if severely shaken, the connection parts of the power line 22 and the connection line 21 are not shorted or electric shock, and the temperature of the inner cylinder 15 can be properly adjusted by the temperature controller 30 connected to the heating coil 20. In addition, the temperature of the regulated state can be kept constant, thereby improving the reliability and value of the product.
