If there is no hollow in the sealing member 170, even if the door 111 is closed and the sealing member 170 is pressed, the door 111 may not be completely closed because it cannot afford to accommodate the deformation amount of the sealing member 170. In addition, the fixing device (not shown) of the door 111 may be damaged.

In addition, since most of the sealing member 170 is formed behind the opaque door inner frame 111b, the sealing member 170 cannot be seen from the outside of the door glass 112, which causes the dryer to appear. The sense of beauty may be improved.

Opposite sides of the sealing parts 171 and 172 is formed with a coupling portion 173 to be mounted to the sealing member mounting portion 116a of the opening 116, the surface of the coupling portion 173 on the inner surface of the sealing member mounting portion 116a. A rib 174 positioned in the formed rib receiving groove 116b is formed. The shape of the sealing member 170 will be described in more detail below.

6 is a cross-sectional view illustrating the sealing member according to FIG. 4, and FIG. 7 is a cross-sectional view illustrating an opening in which the sealing member according to FIG. 6 is mounted.

As shown in FIGS. 6 and 7, the sealing member 170 is formed at the edge of the opening 116 on the opposite side of the sealing parts 171 and 172 which contact the door inner frame 111b and the door glass 112 to perform sealing. A coupling portion 173 for coupling to the protrusion is formed.

At least one rib 174 protrudes from the surface of the coupling portion 173, and the number of ribs 174 is the required sealing capacity or the width W2 of the sealing member mounting portion 116a formed in the opening 116. It is preferable to select in consideration.

At this time, the rib 174 may protrude vertically from the surface of the coupling portion 173, but inclined to the rib 174 in the shape of an arrowhead in order to easily mount the coupling portion 173 to the sealing member mounting portion 116a. Giving is effective.

Meanwhile, a sealing member mounting portion 116a is formed at an edge of the opening 116 to accommodate the coupling portion 173, and a rib accommodation groove 116b engaged with the rib 174 on the inner surface of the sealing member mounting portion 116a. ) Is formed.

At this time, the rib receiving groove 116b preferably has the same shape as the rib 174, and if the rib 174 has an inclination, the rib receiving groove 116b should also be inclined.

The rib receiving groove 116b is formed on the inner surface of the sealing member mounting part 116a so that the rib 174 is engaged with the rib receiving groove 116b, thereby causing the coupling part 173 and the sealing member mounting part 116a to occur. To prevent leakage.

Here, it is preferable to make the width W2 of the sealing member mounting portion 116a larger than the thickness W1 of the coupling portion 173. In the process of fitting the coupling portion 173 to the sealing member mounting portion 116a, 174 to prevent the coupling portion 173 from being fitted.

Leakage may occur through the space between the coupling portion 173 and the sealing member mounting portion 116a by making the thickness W1 of the coupling portion 173 smaller than the width W2 of the sealing member mounting portion 116a.

Such leakage can be prevented by the rib 174 and the rib receiving groove 116a. However, the rib 174 and the rib demand groove 116a need to be firmly maintained at the edge of the opening 116 and the sealing member 170 in case the ribs 174 and the rib demand groove 116a do not maintain a completely hermetic state.

To this end, support parts 176 and 177 are formed on both sides of the coupling part 173. The support parts 176 and 177 include a first support part 176 that supports the outer edge 116c of the opening 116, and a second support part 117 that supports the inner edge 116d of the opening 116.

Since the portion where the second support portion 177 and the inner edge 116d of the opening 116 contact each other is easily exposed to the circulating air inside the drum 120, the second support portion 177 may close the inner edge 116d. It is formed to extend long in contact with the surface of the inner border (116d) so as to sufficiently wrap.

In this manner, the first support part 176 and the second support part 177 are formed to firmly support the outer edge 116c and the inner edge 116d of the opening 116 to further prevent leakage.

The multi-contact sealing member formed of one body described above may be applied to various home appliances such as a drum washing machine as well as a dryer.
