For example, in another alternative embodiment, the micro-channel plasma generator 2 described in the above embodiment before the replacement may be provided between the apparatus case 1 and the laundry accommodation portion 4, and the micro-channel plasma generator 2 may be provided on top of the laundry accommodation portion 4, instead of the micro-channel plasma generator 2 being provided outside the apparatus case 1 or embedded in the apparatus case 1. This arrangement also achieves the effect that liquid enters the mini-channel plasma generator 2 through the liquid inlet 21 and enters the laundry accommodation portion 4 through the liquid outlet 22 after being treated in the mini-channel plasma generator 2. Without departing from the principles of the present invention, and thus, fall within the scope of the present invention.

For example, in another alternative embodiment, the micro-channel plasma generator 2 may be further provided with a gas input (not shown) and a gas valve (not shown) on the basis of the structure described in the previous embodiment. By providing a gas input and a gas valve, when liquid enters the micro-channel plasma generator 2 and air mixed in the liquid is insufficient, the micro-channel plasma generator 2 can be supplemented with air or oxygen through the gas input. In the present embodiment, the air pump is not provided, because an external air supply manner, such as a high-pressure air cylinder air supply, may be employed, and thus the air pump is not necessarily provided. This arrangement also achieves the effect that liquid enters the mini-channel plasma generator 2 through the liquid inlet 21 and enters the laundry accommodation portion 4 through the liquid outlet 22 after being treated in the mini-channel plasma generator 2. Without departing from the principles of the present invention, and thus, fall within the scope of the present invention.
