When the rinsing liquid is recovered by the rinsing liquid recovery step (S23), the drying step (S30) for drying the object to be cleaned is performed.

The drying step (S30) is the suction fan 31 to operate the suction fan 31 and the exhaust fan 32 provided in the washing tank cover 30 to circulate the internal space air of the washing tank 20, the suction fan A suction step S31 in which the 31 is operated and an exhaust step S32 in which the exhaust fan 32 operates are performed.

At this time, the suction step (S31) and the exhaust step (S32) may be carried out at the same time, it will be also possible if the exhaust step (S32) is configured to proceed after the suction step (S31).

When drying of the to-be-cleaned object is completed by the suction step (S31) and the exhaust step (S32), the user is separated from the washing tank 20 by separating the wash object from the fixing part 70 ( S33) proceeds.

When the cleansing object is separated from the washing tank 20 by the separating step S33, the flux washing of the cleansing object is completed.

On the other hand, the air supply step (not shown) to further proceed to remove the rinse liquid on the object to be cleaned by spraying the high-pressure air through the air injection hole 63 in the drying step (S30). It is possible.

Through such a process, the flux adhering to the chain, nozzle plate, heat exchanger, filter, etc. is automatically cleaned and removed, so that the flux can be removed more efficiently and safely than when the flux is removed manually.

In addition, one side of the case 10 may be further provided with a device for generating an ultrasonic wave or vibration. In this case, ultrasonic waves or vibrations may be provided to the inner space of the washing tank 20 so that ultrasonic waves or vibrations are applied to the washing liquid to remove the flux of the object to be cleaned.

When ultrasonic waves or vibrations are applied, washing of the flux by the washing liquid contained in the inner space of the washing tank 20 is more effectively enabled.

According to the flux automatic washing machine and the flux automatic washing method according to the present invention as described above, it can be expected that the convenience and efficiency of use, the user safety is greatly improved.

As such, the flux automatic washing machine and the flux automatic washing method according to the present invention will have a variety of advantages, so it will be highly applicable to the industry.
