Referring to FIGS. 2 and 3, the odor removal unit 80 comprises a flexible odor removal hose 81 diverging from the circulation hose 52 and connected to an opening 2aa on the lower surface of the seal 2, and a switching valve 82 mounted at the level of the odor removal hose 81. The opening 2aa is provided with a filter network 84 for preventing the blockage of the circulation hose 52 by a foreign substance. sucked inside. The odor removal hose 81 is connected to the circulation hose 52 by a Y-connector 83, therefore a portion of the water supplied to the vessel 3 through the circulation hose 52 is fed into the hose odor removal hose 81. The water is ejected from the opening 2aa by the odor removal hose 81 to thereby remove a pollutant P remaining in the folded portion 2a of the seal 2. The valve switching circuit 82 is in the form of a solenoid valve and is open during a rinsing process. Thus, when the circulation pump 51 (see FIG. 1) is actuated during the rinsing process and the water is then supplied to the vessel 3, a part of the water can be fed into the elimination hose. 81. Therefore, while the laundry is rinsed, the pollutant remaining in the folded portion 2a of the seal 2 is also eliminated. FIGS. 4a, 4b and 4e show a process according to which a pollutant is removed by ejection of water through the aperture of FIG. 3. Referring to FIGS. 4a to 4e, the entire pollutant P remaining in FIG. the folded portion 2a of the seal 2 is progressively eliminated by ejecting water from the opening 2aa through the odor removal hose 81. 7 Therefore, it is able to prevent the pollutant from rotting , thus preventing it from feeling bad in the drum washing machine. In addition, it is able to prevent the pollutant from promoting moisture in the wet drum washing machine, thus preventing it from feeling bad inside due to mold. FIG. 5 represents a diagram showing a variant of the odor elimination unit in FIG. 1 and FIG. 6 represents a perspective view showing a main part extracted from the odor elimination unit of FIG. 5.

Referring to FIGS. 5 and 6, the odor removal unit 80 comprises an injection nozzle 85 mounted at the opening 2aa of the lower surface of the seal 2, the disposing hose odors 81 diverging from the circulation hose 52 and connected to the injection nozzle 85 and a switching valve 82 mounted at the level of the odor removal hose 81. The injection nozzle 85 ejects water supplied by the odor removal hose 81 from an injection hole 85a at a constant angle O. In this embodiment, the water is ejected at an angle of about 120 °. As the water is ejected at the constant angle, the water is spread over a large area of the bottom surface of the seal 2. Therefore, it is able to effectively remove the pollutant spread over the large area. And, since the water is ejected from the injection hole 85a, it is able to strongly remove the pollutant by an injection force. As the odor removal hose 81 is connected to the circulation hose 52 through the Y connector 83, a portion of the circulated water supplied to the vessel 3 is supplied to the odor removal hose 81 by the circulation hose 52. The supplied water is ejected from the injection hole 85a of the injection nozzle 85 through the odor removal hose 81 to thereby remove the pollutant P remaining in the folded portion 2a seal 2.

The switching valve 82 is in the form of a solenoid valve and is open during a rinsing process. Therefore, when the circulation pump 51 (see FIG. 1) is actuated during the rinsing process and the water is thus supplied to the tank 3, a part of the water can be fed into the flexible pipe 8 Accordingly, while the laundry is rinsed, the pollutant remaining in the folded portion 2a of the seal 2 is also removed. As the pollutant is removed, it is able to prevent the pollutant from promoting moisture in the wet-drum washing machine, thus preventing it from feeling bad inside due to mold. As mentioned above, the drum washing machine according to the present invention comprises a flexible odor removal hose diverging from the circulation hose and connected to the opening of the lower surface of the seal. As a result, the pollutant remaining in the seal is removed by the water ejected from the odor removal hose. And in the case where the injection nozzle is mounted at the opening, the water is spread over the large area of the bottom surface of the seal, therefore, it is able to effectively remove the pollutant spread over the large area. It is also able to strongly eliminate the pollutant by the force of injection.

Therefore, it is able to prevent the pollutant from rotting and to prevent it from feeling bad in the drum washing machine. It is able to prevent the pollutant from promoting moisture in the wet drum washing machine, thus preventing it from feeling bad inside due to mold.
