Definitions

• This disclosure relates to an automatic hair washing device.
• Patent Document 1 Conventionally, in hair salons and other beauty salons, there has been an automatic hair washing machine described in Patent Document 1 below (hereinafter referred to as the "Publication 1 Invention") as a device that automatically washes a person's hair without the hands of a practitioner.
• Publication 1 Invention a cover that covers the person's head opens and closes using the top of the head as a hinge. This type of structure does not cause any problems when the practitioner stands next to the automatic hair washing machine and handles the hair from the side of the person's head after the treatment.
• treatment from the back position there has been an increase in cases where the practitioner stands behind the automatic hair washer and handles the hair from the top of the head after treatment with the automatic hair washer (hereinafter referred to as "treatment from the back position").
• treatment from the back position if the cover opens and closes using the top of the head as a hinge, it will interfere with the practitioner. For this reason, there are also automatic hair washer covers that open and close from the left and right.
• the cover when the cover opens and closes from side to side, it crosses the front of the recipient's face when opening and closing, which can cause water droplets adhering to the inside of the cover to drip and wet the recipient's face.
• This disclosure was proposed in light of the above-mentioned circumstances, and aims to provide an automatic hair washing device that prevents water droplets from hitting the face of the person being treated when the hood is opened or closed.
• the automatic hair washing device comprises a freestanding main body, a bowl on top of the main body on which the head of the person to be treated is placed, a hood that covers the top of the bowl, and a rotating shaft that connects the bowl and hood, the rotating shaft being positioned to the side of the head of the person to be treated that is placed in the bowl, and facing away from the front part of the main body on which the body of the person to be treated is placed towards the rear part of the main body that is opposite the front part of the main body, and sloping downward from the front part of the main body towards the rear part of the main body.
• the automatic hair washing device is characterized in that the hood section has a front hood section formed with a face opening for exposing the face of the person being treated, and a rear hood section connected to the front hood section and covering the periphery of the head of the person being treated, and the periphery of the hood section, which overlaps the periphery of the bowl section, slopes downward from the front hood section toward the rear hood section.
• the automatic hair washing device is characterized in that the rear hood portion, on the opposite side of the rotating shaft portion relative to the rear hood portion, corresponds to the curved surface of a hemisphere whose diameter is the width of the left and right sides of the hood portion.
• the automatic hair washing device disclosed herein is characterized in that a recessed portion for the practitioner's legs to be placed is formed on the rear surface of the main body, which is opposite the front surface of the main body where the patient's body is placed.
• the automatic hair washing device is characterized in that the hood section has a plate formed at both lower ends of the hood front section, protruding inward, on the opposite side of the rotary shaft section relative to the face opening.
• the automatic hair washing device disclosed herein is characterized in that the plate extends toward the rear surface of the hood.
• the automatic hair washing device disclosed herein is characterized in that the extended tip of the plate is tapered.
• the automatic hair washing device comprises a freestanding main body, a bowl on top of the main body on which the recipient's head is placed, a hood that covers the top of the bowl, and a rotating shaft that connects the bowl and hood.
• the rotating shaft is positioned to the side of the recipient's head, which is placed in the bowl, and faces away from the front part of the main body's outer surface, where the recipient's body is placed, towards the rear part of the main body, which is opposite the front part of the main body, and is inclined downward from the front part of the main body to the rear part. Because the rotating shaft is inclined, the rotational trajectory of the hood is also inclined.
• the front part of the hood crosses a position that is shifted rearward from the front of the recipient's face, making it less likely that water droplets adhering to the inner surface of the hood will hit the recipient's face, even if they do drip. Furthermore, because the hood is inclined, water droplets flow toward the rear part of the hood as they travel along the inner surface and edges of the hood, making it less likely that they will hit the recipient's face.

• the hood section will protrude rearward when it opens, causing it to interfere with the practitioner working in the back position or with the wall behind the automatic hair washing device.
• the side of the hood rear section opposite the rotating shaft from the rear hood section corresponds to the curved surface of a hemisphere with the lateral width of the hood section as its diameter. Therefore, when the hood section opens, the side of the hood rear section opposite the rotating shaft does not protrude outward by the amount of the curved surface. As a result, the hood section does not interfere with the practitioner when it opens.

Water droplets adhering to the inner surface of the hood part flow along the plate, allowing them to flow away from the face of the person being treated. Furthermore, when the hood part is closed and the automatic hair washing device is operating, water droplets inside the bowl part can be prevented from scattering through gaps in the hood front part.

If the plate were excessively large, it could excessively obstruct water splashing inside the bowl when the hood is closed and the automatic hair washing device is operating, hindering hair washing. However, because the plate is tapered, hair can be properly washed while preventing it from splashing out of the gaps in the front of the hood.
