A rotation center hole 311 and a tilting guide 312 are formed on the slide bracket 310 in correspondence with the rotation center screw shaft 231 and the tilt adjustment screw shaft 232 of the tilting bracket 230, .

First, the rotation center hole 311 is inserted into the rotation center screw shaft 231 of the tilting bracket 230, thereby becoming the center of rotation of the heat generator 200.

The tilting guide 312 is an arcuate guide having a predetermined angle formed on a predetermined radius around the rotation center hole 311. The inclination adjusting screw shaft 232 is inserted through the tilting guide 312, The tilt adjusting screw shaft 232 moves in the tilting guide 312 in the radial direction.

At this time, a first fastening means 510 such as a butterfly nut is fastened to the rotation center screw shaft 231 protruding through the rotation center hole 311 so that the heat generating part 200 can be inserted into the slide part 300 And a second fixing means 520 such as a butterfly nut is fastened to the tilt adjusting screw shaft 232 protruding through the tilting guide 312 to prevent the second fixing means 520 from rotating. The current tilt angle, that is, the tilt angle is maintained.

This operation is illustrated in detail in FIG.

8A shows a state in which the heating unit 200 is oriented upwardly, FIG. 8B shows a state in which the heating unit 200 is oriented in an oblique direction, and FIG. 8C shows a state in which the heating unit 200 200 are oriented forward.

The tilting bracket 230 is attached to both sides of the heat generating part 200. The first and second fastening means 510 and 520 can be fastened to each other without the tilting bracket 230, So that they are directly fastened to the heat generating part 200 with a bolt.

The tilting bracket 230 having both the rotation center screw shaft 231 and the inclination adjusting screw shaft 232 may be connected to both sides of the heat generating unit 200 as described above. The inclination adjusting screw shaft 232 may be formed on only one of the left and right sides to perform the inclination adjusting function.

Next, a structure for preventing the slide bracket 310, which is guided by the guide bracket 120 and ascends and descends, from being separated upward from the guide bracket 120 will be described.

That is, in the present invention, a cover bracket 130 bent at a right angle is fixed to the upper end of the guide bracket 120, and a lower portion of the slide bracket 310 is bent at right angles to the cover bracket 130, The stopper 313 is formed so that when the slide bracket 310 moves upwardly of the guide bracket 120, the stopper 313 comes into contact with the cover bracket 130, .

At this time, the cover bracket 130 corresponds to a plate bent at a right angle, and is fixed to close the upper end of the guide bracket 120.

The stopper 313 may protrude from the cover bracket 130 so as to interfere with the cover bracket 130. The stopper 313 may be attached to the slide bracket 310. However, It is preferable that a part of the slide bracket 310 is cut into a substantially 'C' shape and then bent at a right angle.

When the slide bracket 310 reaches the end of the guide bracket 120 when the slide bracket 310 moves upward, the stopper 313 is engaged with the cover bracket 130 fixed to the upper end of the guide bracket 120, So that the slide bracket 310 is prevented from being separated from the guide bracket 120.

Lastly, in order to prevent the center of gravity from varying and collapse when the heating portion 200 of the height-controlled electrothermal heater of the present invention is tilted, in the present invention, The base plate 110 may be formed to extend eccentrically from the side of the vertical vertical center line O toward the front side where the heating unit 200 is tilted.

4, the rotation center hole 311 and the base plate 110 are eccentrically formed forward from the side vertical center line O, that is, leftward in the drawing, so that even if the heating unit 200 is tilted, There is no collapse.

At this time, the lock pin 420 provided on the slide bracket 310 repeatedly rides on the inclined surface of the one-way inclined protrusion 410 formed on the guide bracket 120 as shown in FIG.

When the user lifts the heating unit 200 to a desired height and then places the heating unit 200 thereon, the lock pin 420 elastically protrudes over the edge of the unidirectional slant projection 410 of a predetermined height, The current height is maintained.

In contrast, when the user desires to lower the height of the heat generating portion 200, when the user grips the handle 422 of the lock pin 420 with both hands and pulls the lock pin 420 to both sides, the lock pin The shaft 421 of the guide shaft 420 is pulled out and then the heating unit 200 is guided by the guide bracket 120 due to its own weight and descends.

When the user releases the lock pin 420 after lowering the heating unit 200 to a desired height, the lock pin 420 is rotated by the restoring force of the coil spring 424 supported by the snap ring 423 So that the heat generating part 200 can maintain its current height by being extended over the edge of the one-way slanting protrusion 410 of a predetermined height.

When the tilting angle of the heating unit 200 is to be adjusted, the tilting bracket 230 is rotated by the tilting bracket 230 so that the tilting bracket 230 rotates about the rotation center screw shaft 231 and the tilting screw shaft 232, The first fastening means 510 and the second fastening means 520 are slightly loosened.

Accordingly, the heating unit 200 can adjust the inclination with reference to the rotation center screw shaft 231. When the angle of the heating unit 200 is adjusted to a desired angle by the user as shown in FIG. 8 The first fastening means 510 and the second fastening means 520 may be tightened to maintain the current angle of the heat generating unit 200 at an adjusted angle.

As described above, when the height adjustment and the inclination adjustment of the heat generating unit 200 are completed, the switch 260 in the off state is turned on to supply power to the heat generating unit 210 of the heat generating unit 200 Accordingly, the heating unit 210 dissipates the heat of resistance according to the power supply, so that the heating is performed.

Therefore, the height-adjustable electrothermal heater of the present invention can easily adjust the height of the heating unit 200 for heating by using the resistance heat to a height desired by the user, Also, it can be easily adjusted, which greatly improves the usability of the user.

A separate cover bracket 130 may be provided to prevent the slide unit 300 from being separated from the base unit 100 when the height of the heat generating unit 200 is adjusted, The center of gravity of the center of gravity is designed to be eccentric in preparation for tilting, so that even if the inclination angle of the heat generating part 200 is adjusted, there is no possibility of collapse, and thus it is advantageous to use safely.
