The heater device includes a heater case 171, a support plate 180 provided inside the heater case 171, and insulators 190 fastened to the support plate 180.

At this time, the heater case 171 is disposed below the drying drum 130, and is connected to the hot air supply duct 172 (see FIG. 1).

In this heater case 171, two case portions corresponding to each other are assembled to form a cylindrical structure.

Of course, the shape of the heater case 171 is not limited to that of the structure in which the coil heater 170a is stably disposed therein and efficiently generates hot air.

The support plate 180 is disposed inside the heater case 171 and is preferably installed between the two cases so as to divide the inside of the heater case 171 into two parts. That is, when the two case parts are assembled to each other, both sides of the support plate 180 are inserted therebetween and fastened together.

As the support plate 180 divides the inside of the heater case 171, a space for inserting the insulator 190 to be fastened to the support plate 180 is provided and air introduced into the heater case 171 is supplied to the insulator 190 so as to be efficiently heated by the coil heater 170a.

The insulator 190 is fastened to the support plate 180 and a coil heater 170a for heating the air flowing into the heater case 171 is wound.

The insulator 190 is a member necessary for installing the coil heater 170a on the heater device, and structurally supports and electrically insulates the coil heater 170a.

At this time, the insulator 190 has grooves or gaps such that the coil heater 170a is wound on the both ends in the longitudinal direction, that is, on the upper and lower sides in the drawing, More than one is installed.

Of course, it is preferable that the insulator 190 is made of a magnetic material having excellent insulating performance.

Hereinafter, the fastening structure of the insulator 190 with respect to the support plate 180 will be described with reference to FIGS. 4 and 5. FIG.

The support plate 180 has an opening 184 having a predetermined width for inserting and inserting the insulator 190 wherein the opening 184 corresponds to the cross section of the insulator 190 so that the insulator 190 can be inserted Shape.

The insulator 190 is inserted into the opening 184 of the support plate 180 to a certain extent and then the fitting groove 192 is formed in the both sides of the insulator 190 so that the support plate 180 is inserted.

The opening 184 of the support plate 180 is connected to the first edge 184a, the second edge 184b, and the third edge 184b so that the opening 184 of the support plate 180 is engaged with the support plate 180 when the insulator 190 is inserted and then rotated. And a rim 184c.

The first rim 184a faces away from each other by a length in which the insulator 190 can be inserted. The first rim 184a may be formed to correspond to both sides of the insulator 190 to be inserted.

The second rim 184b is also configured to guide the insulator 190 from the first rim 184a so that the insulator 190 is rotatable with the support plate 180 sandwiched in the fitting groove 192. [

That is, the second rim 184b extends from the first rim 184a and the distance between the second rim 184b and the second rim 184b facing each other is smaller than the distance between the fitting grooves 192 formed on both sides of the insulator 190 .

This second rim 184b is preferably formed to extend from the first rim 184a by a distance that the insulator 190 is inserted at the first rim 184a of the opening 184 and rotated about 45 degrees .

Meanwhile, the third rim 184c protrudes inward from the second rim 184b to intercept the rotation of the insulator 190. As shown in Fig.

That is, the third rim 184c bends from the second rim 184b into the inner space of the opening 184 and engages the fitting groove 192 of the rotating insulator 190, So that it is not rotated any more.

As described above, the opening 184 of the support plate 180 is configured to be able to be tightened when the insulator 190 is rotated after a certain degree of rotation.

However, the tightening of the insulator 190 with respect to the support plate 180 is not performed closely, so that vibration noise may be generated from the insulator 190 due to vibration caused by the operation of the drier.

In other words, the insulator 190 fastened to the support plate 180 has a state in which the fastening portions of the support plate 180 are spaced apart from each other by a certain distance in the fitting groove 192, .

The pressing portion 182 may include an upper inner surface and a lower inner surface of the fitting groove 192 of the insulator 190, That is, a structure protruding toward both inner surfaces.

The pressing portion 182 is bent and protruded so as to be able to be detached for a certain degree when fitted into the fitting groove 192 of the insulator 190.

The pressing portion 182 protrudes higher than the height from the lower side inner surface of the fitting groove 192 to the upper side inner surface in order to press the fitting groove 192 of the insulator 190, 182 can be fitted into the fitting groove 192 of the insulator 190. [

Alternatively, although not shown in the drawings, the pressing portion may have an inclined outer surface. The contact surface of the fitting groove 192 of the insulator 190 with respect to the pressing portion can reach the position of the pressing portion while sliding on the pressing portion when the pressing surface of the pressing portion 182 is inclined.

According to the present invention configured as described above, since the pressing portion 182 for pressing the insulator 190 against the insulator 190 is provided at the inserting portion of the supporting plate 180 with respect to the insulator 190, The vibration due to the gap can be blocked to prevent the generation of vibration noise.
