If the connection is normal, the process proceeds to the rinsing process after the dewatering process, and the stroke control means 19 operates the water supply valve 9 again via the water supply valve control means 22 to supply water to the set water level, and then the motor By operating the control means 20, the motor 6 is driven for a predetermined time at a constant inversion cycle according to the set water level, the laundry is rinsed by the stirring blade 4, and the rinsing process is completed.

After the end of the rinsing and rinsing process, before moving to the draining process, the second joint portion 12 of the in-machine hose 10 and the
A signal from the connection detecting means 19 for detecting the connection of No. 4 is input to the stroke control means 20. If the connection is normal, the process shifts to a draining step, the drain valve 8 is operated to drain, final dehydration is performed, and the process is terminated. I do. If the connection between the second joint portion 12 and the external hose 14 is insufficient or not connected, the stroke control means 20 stops the operation of the drain valve 8 via the drain control means 22, and the water tank 2 Stop draining water inside. At the same time, the information is recognized and displayed by the display means 28, and a warning is notified by the notifying means 29.

As described above, according to the present embodiment, before the washing, rinsing, and dewatering steps are performed, the second output of the in-machine hose 10 is detected by the detection output from the connection detecting means 19 before the drainage step.
Connection between the outer joint 14 and the outer joint 14 is detected, and if the connection between the second joint 12 and the outer hose 14 is insufficient or not connected, the drainage in the water tank 2 is stopped. Therefore, if the user forgets to attach the external hose 14 and the external hose 14 is incompletely attached and comes off due to vibration or the like during use of the washing machine, the drainage process is stopped to increase the size due to water leakage. Damage can be prevented. . Also, at the same time, the connection state of the external hose 14 can be confirmed by recognizing and displaying by the display unit 28 and issuing a warning by the notifying unit 29, and it is possible to prevent the damage caused by water leakage and overflow.

In the above-described embodiment, the connection detecting means 1 is provided before moving to the draining step in each of the washing, rinsing and dehydrating steps.
9, the connection between the second joint portion 12 of the in-machine hose 10 and the outer hose 14 is detected. However, by detecting before the start of the washing process, the outer hose 14 is normally connected. It can be checked before driving whether it has been inserted or forgotten, and it is incompletely inserted,
The damage caused by water leakage and overflow can be prevented.
