Furthermore, the fabric may be washed away with floating dust and surface stains that are easily removed by pre-washing with clean washing water supplied through the rinse water pipe 14.

Preferably, the medical washing machine further comprises a heating device 11 fixedly arranged between the elution outer cylinder 2 and the elution inner cylinder 3, and the heating device 11 is used for heating, so that the temperature of liquid in the elution outer cylinder 2 during washing can be increased, the activity during washing can be improved, and the washing effect can be improved.

The working process is as follows: placing the fabric to be washed into the elution inner cylinder 3, closing the sealing door 4, opening the rinsing water valve 16 to enable a proper amount of clean cleaning water to enter the elution outer cylinder 2, starting the driving device 9 to drive the elution inner cylinder 3 to rotate for pre-washing, and washing away floating dust and surface dirt which are easy to remove in the fabric. After the completion of the prewashing, the drain valve 15 is opened to drain the liquid after the prewashing. And opening the alkaline liquid valve 17 to enable an appropriate amount of alkaline liquid for washing in the alkaline liquid tank 5 to enter the elution outer cylinder 2, and driving the elution inner cylinder 3 to rotate by using the driving device 9 to perform main washing without adding a detergent. After the main washing is finished, the acid liquor valve 18 is opened, so that the acidic neutralization liquid in the acid liquor tank 6 enters the interior of the elution outer cylinder 2 for neutralization reaction. In the neutralization reaction process, the elution inner cylinder 3 can rotate or not move, and the neutralization reaction can be more sufficient when the elution inner cylinder 3 rotates. After the neutralization reaction is completed, the liquid in the elution outer cylinder 2 is discharged. After the main washing is finished, rinsing is carried out, and the rinsing process is the same as that of the pre-washing, which is not described herein again. After rinsing, a dewatering step may also be carried out, in which drain valve 15 remains open until the fabric is washed.
