Since the liquid is supplied sequentially to each row, the hair washing process can be carried out effectively and economically without wasting liquid.

In addition, the hair washing machine can be used not only to perform continuous operations from the first step as described above, but also to perform continuous operations from intermediate steps such as the rinsing step. If the work process change switch 64 is operated appropriately when the power switch 59 is on but the machine is not operating, the process to be performed will be changed, and the change will be displayed on the process display lamp 53 and can be confirmed. After checking, if the start switch 60 is turned on, continuous work from the desired process onwards can be carried out.

Since the present invention is configured and operates as explained above, it brings about various effects described below.

The brush holding mechanism set on the brush stand allows the brush groups to move forward and backward independently, so the brush groups follow the shape of the head and can be moved evenly and accurately according to the size of the head. The brush can be brought into contact with the scalp at the top, sides, and rear of the head, allowing the scalp and hair to be thoroughly washed.

By selecting and using the compression coil spring of the brush mechanism that has the optimum elastic force, it is possible to safely and optimally apply a contact load to the scalp, and to comfortably perform dandruff removal and pine surgery.

The concave part provided in the base tube of the brush mechanism is formed to the optimum length to limit the range in which the base tube moves forward and backward within the receiving tube to an appropriate range for contact with the scalp, so that the head can be moved into the brush group. It is easy to insert and can thoroughly wash the scalp.

Since the cleaning liquid is ejected only from the nozzle row corresponding to the position of the brush stand, the amount of liquid used can be reduced, and the tank containing the cleaning liquid can be made smaller.The height of the hair washing casing can also be adjusted, and the shoulder rest stage can be adjusted. The head insertion opening of the hair washing casing is designed to allow the patient to wash their hair in a comfortable position, and the head insertion opening of the hair washing casing is configured to allow the direction of the head insertion opening to be changed and adjusted, making it easier for caregivers to handle the device. It can be used conveniently.
