3 is a perspective view illustrating a clothes processing apparatus to which a heater according to an embodiment of the present invention is applied. 3 shows a drum washing machine 100 equipped with a steam generator using a heater according to an embodiment of the present invention as an example of a clothes processing apparatus.

Referring to FIG. 3, the drum type washing machine 100 includes a cabinet 101 having an outer appearance, a cylindrical tub 102 supported horizontally in the cabinet 101 to store washing water, (Not shown) for driving the drum 103 and at least one or more steam generating devices 200 for supplying steam into the drum 103 .

At this time, a water supply valve 104 is connected to one side of the drum washing machine 100 to supply water to the tub 102.

A water supply port 201 connected to the water supply valve 104 of the drum washing machine 100 is formed at one side of the steam generating device 200 through a water supply pipe 105. At the other side of the steam generating device 200, A steam discharge port 202 through which a steam supply pipe 106 is connected to supply steam generated inside the drum 103 is formed.

The steam supply pipe 106 is preferably formed in a nozzle shape so that steam can be smoothly injected into the inner space of the drum 103. The end of the steam supply pipe 106 is exposed to the inside of the drum 103 As shown in FIG.

Therefore, it is preferable that the steam generating device 200 is installed on the upper side of the tub 102 so that the flow path connecting the water supply valve 104 and the steam supply pipe 106 is relatively short and the repair and inspection are easy.

Here, a heater is installed inside the steam generator 200, and the heater will be described in detail below.

FIG. 4 is an exploded perspective view showing the heater according to FIG. 3, FIG. 5 is a view showing one end of a heater equipped with the heating unit fixing means according to FIG. 3, and FIG. 6 is a cross- FIG.

4, the heater 210 according to an embodiment of the present invention includes a heater 211 having a heater thermal fuse (see 19 in FIG. 2) incorporated therein, a heater 210 having a heater 210 installed therein, An outer bracket 214 for mounting the heat generating unit 211 to the processing apparatus, a sealing member 212 closely attached to one side of the outer bracket 214, and a sealing member 212 facing the outer bracket 214 And at least one of the heat generating portion 211 and the inner bracket 213 is provided with a heat generating portion for preventing the heater thermal fuse 18 from being broken, A fixing means 218 is mounted.

Here, the heat generating unit fixing unit 218 may prevent the heat generating unit 211 from being shaken by the inner bracket 213.

Meanwhile, the inner bracket 213 is provided with an elongated fastening rod 213a, and a thread 213b is formed at an end of the fastening rod 213a. At this time, after the fastening rod 213a passes through the sealing member 212 and the outer bracket 214, the nut 217 is fastened to the thread 231b of the fastening rod 213a so that the heat generating portion 211, The bracket 213, the sealing member 212, and the outer bracket 214 are coupled together to form one heater 210.

Here, the heat generating portion 211 is in the form of a substantially hollow pipe, and a terminal 217 for supplying electricity is attached to one end thereof.

The heating unit fixing unit 218 is mounted on the heat generating unit 211 so as to face the sealing member 212 with respect to the inner bracket 213. The inner bracket 213 is in close contact with the sealing member 212 .

With the above-described configuration, when the heater 210 is mounted or attached, or the vibration generated when the drum washing machine 100 is carried or used, the fastening state of the heat generating portion 211 and the inner bracket 213 is loosened (See 18 in FIG. 2) of the heater thermal fuse (see 19 in FIG. 2) connected to the heat generating portion 211 can be prevented from being cut off.

5 and 6, the heating unit fixing means includes a flange 218 mounted on the heat generating portion 211 and a flange 218 formed on the inner bracket 213 to allow the flange 218 to pass therethrough. And a mounting hole 213d.

The flange 218 is made of a material having elasticity and functions to press the inner bracket 213 toward the sealing member 212 when the inner bracket 213 and the outer bracket 214 are connected to each other.

That is, before the inner bracket 213, the sealing member 212 and the outer bracket 214 are mounted on the heat generating portion 211, the flange 218 formed of an elastic body such as a rubber ring is first attached to the heat generating portion 211 And the flange 218 is transferred to the approximately middle position of the heat generating portion 211. The flange 218 is moved to the inner bracket 213 side after the inner bracket 213, the sealing member 212 and the outer bracket 214 are fastened by the fastening rod 213a of the inner bracket 213, The inner bracket 213 and the sealing member 212 are brought into close contact with each other so that the heat generating portion 211 can be reduced to some extent in the state where the heat generating portion 211 is fastened to the inner bracket 213.

5, the flange 218 is in close contact with the inner bracket 213 with the inner bracket 213, the sealing member 212, and the outer bracket 214 fastened together.

6, heat-generating-portion inserting holes 213c through which the pipe-shaped heat-generating portions 211 can pass are formed on both sides of the inner bracket 213, and the heat-generating-portion inserting holes 213c and the heat- A flange mounting hole 213d is integrally formed.

Here, the flange 218 may fill the heat generating portion insertion port 213c or the flange mounting hole 213d. That is, not only the gap formed between the heat-generating-portion inserting hole 213c and the heat-generating portion 211 but also the flange mount 213d is completely filled with the flange 218 so that the heat- So that there is no margin for moving, and thus it is possible to prevent the heat generating portion 211 from shaking. In this case, if the flange 218 is formed using silicon or the like, the gap between the heat-generating-portion inserting hole 213c and the heat-generating portion 211 can be more reliably filled.

If the flange 218 is in the shape of a ring, the flange mount 213d may not be formed separately, but the heat generating portion insertion port 213c may be formed slightly larger than the outer diameter of the heat generating portion 211 so that the flange 218 can pass therethrough. have.

6, when the flange mount 213d is formed symmetrically (that is, almost straight) with respect to the heat-generating-portion inserting hole 213c, the flange 218 is fixed by the heat- It may be more effective to use a straight nut or the like. That is, modified examples of the heat generating portion fixing means will be described below.

FIG. 7 is a perspective view showing a modified example of the heating unit fixing means according to FIG. 6, and FIG. 8 is a perspective view showing another modification example of the heating unit fixing means according to FIG.

The heating unit fixing means is a fastening member 219 fastened along a thread formed on the heat generating unit 211. That is, when a thread is formed on the outer circumferential surface of one end of the heat generating portion 211 and the nut 219 fastened to the thread is fastened toward the inner bracket 213, the joined state of the heat generating portion 211 and the inner bracket 213 is loose Can be prevented.

Here, it is preferable to use a straight nut or a wing nut as shown in FIG. 7, rather than using a normal hexagonal nut or the like as the heating unit fixing means 219. The reason is that when a hexagon nut or the like is used, it is inconvenient to use a spanner or the like as a separate tool for tightening the nut. However, in the case of using a straight nut or a butterfly nut, even if a fastener such as a spanner is not used, It is possible to apply a sufficiently strong fastening force.

A screw thread 219b is formed on the inner diameter portion of the screw nut 219 so as to engage with the thread of the heat generating portion 211. A grip portion 219a is formed on the outer diameter portion so that the operator can hold the screw 219a by hand have.

  The inner bracket 213 may further include a nut penetrating portion through which the grip portion 219a of the flat nut 219 can pass. At this time, it is preferable that the nut penetrating portion has a shape similar to the flange mounting hole 213d shown in FIG. Since the grip portion 219a of the butterfly nut 219 is formed in a substantially straight shape, the nut penetration portion should also be formed in a substantially straight shape with reference to the heat generating portion insertion port 213c.

In this case, the nut penetrating portion 213d is integrally formed with the heat generating portion inserting hole 213c, which can increase the productivity.

Further, by attaching a flange 218 made of an elastic material between the flat nut 219 and the inner bracket 213, the fastening force of the nut 219 can be further increased. This is because an elastic material flange 218 is pushed between the nut 219 and the heat generating portion 211 when the butterfly nut 219 is tightened to prevent the nut 219 from being loosened.

On the other hand, a clamp, a pin, or the like may be applied to the heat generating portion fixing means in addition to the nut. In Fig. 8, a clamp 220 which can be used as the heating portion fixing means is shown.

The clamp 220 is cylindrical in which one side is opened, and a fastening part 220a is bent at one side of the opening. A fastening hole 220b for mounting a bolt or the like is formed on the fastening portion 220a.

When the clamp 220 is used, it is not necessary to form the flange mounting hole or the nut penetrating portion 213d in the inner bracket 213. When the inner bracket 213 and the outer bracket 214 are engaged with each other, The clamp 220 may be mounted on the heat generating part 211 so that the pressing part 213 can be pressed toward the sealing member 212.

In addition, a pinhole (not shown) may be formed in the heat generating portion 211 and a pin (not shown) may be inserted into the pinhole. At this time, it is effective that the pin hole is formed at a position where the pin can push the inner bracket 213 toward the sealing member 212 sufficiently. For this purpose, a pin hole is formed at a position where the inner bracket 213 and the outer bracket 214 are engaged with each other so that the surface of the inner bracket 213 and the pin can contact each other while being in contact with each other.

Although the heater 210 used in the steam generator 200 of the drum washing machine 100 has been described above, it is needless to say that the heater 210 may be used in other forms.
