AI Technical Summary

Benefits of technology

[0016]According to the invention, as the detergent supply container comprise a stationary body 21 fixed on the washer body 11 and the drawable body 22 detachably engaged with the stationary body 21 into which the detergent is poured, and the pumping means 50 having the electric contacts is provided on the stationary body 21 to pump the liquid detergent to the outside of the accommodation space 23 in which the drawable body 29 Is inserted, the liquid detergent in the drawable body 22 is pumped out by the pumping means 50 installed on the stationary body 21, and the repeated drawing actions of the drawable body 22 may not incur the failure of the contacts of the detergent supply container. And, as the pumping means 50 having electrical contacts or electrical part is placed in the space partitioned from the drawable body 22, the electrical reliability of the device is secured, and in spite of the flow of the liquid detergent or water, the electrical contacts and the electrical parts may be kept in waterproof condition and failure or malfunction of the drum washer could be prevented.

[0017]Moreover, as the drawable body 22, is provided with the tubular connector 39 extending on the detergent supply port 30 of the drawable body 22 and the packing member 40 on the outer surface of the tubular connector 39, the packing member 40 comprising the end packing 41 and a plural packing fins 42, the airtightness between the detergent supply port 30 of the drawable body 22 and the
