Abstract
Description
Technology Field
[0001] The present disclosure relates to an automatic hair washing device. Background Technology
[0002] Conventionally, in beauty facilities such as hair salons, there is a device that automatically washes a patient's hair without the need for the practitioner's hands, such as the automatic hair washer described in Patent Document 1 below (hereinafter referred to as "Invention of Publicly Disclosed Document 1"). In the invention of Publicly Disclosed Document 1, a cover covering the patient's head opens and closes the crown side using a hinge. This structure does not cause any inconvenience when the practitioner handles rinsing or bundling the hair after treatment with the automatic hair washer while standing at the side of the automatic hair washer and handling the patient's head.
[0003] On the other hand, in recent years, there has been an increase in cases where the stylist handles the rinsing or binding of hair after treatment with an automatic hair washer by standing behind the automatic hair washer and handling it from the crown side of the patient (hereinafter referred to as "handling in the back position"), but if the cover opens and closes with the crown side as a hinge, it interferes with the stylist. For this reason, there are also automatic hair washers in which the cover opens and closes in the left and right directions. Prior art literature
[0004] Japanese Patent Publication No. 6041973 The problem to be solved
[0005] However, when the cover is opened and closed in the left and right directions, as the cover crosses the front of the patient's face during opening and closing, water droplets attached to the inner surface of the cover may fall off, and the patient's face may get wet.
[0006] The present disclosure is proposed in consideration of the above circumstances and aims to provide an automatic hair washing device that prevents water droplets from coming into contact with the face of the patient when the hood is opened or closed. means of solving the problem
[0007] To achieve the above objective, the automatic hair washing device related to the present disclosure comprises a self-standing main body, a bowl portion on which the head portion of a patient is placed above the main body, a hood portion covering the upper part of the bowl portion, and a rotating shaft portion connecting the bowl portion and the hood portion, wherein the rotating shaft portion is positioned to the side of the patient's head portion placed in the bowl portion, and is directed toward the rear portion of the main body opposite to the front portion of the main body portion, from the front portion of the main body portion where the patient's body is placed, and is characterized by being inclined downward from the front portion of the main body portion toward the rear portion of the main body portion.
[0008] The automatic hair washing device related to the present disclosure is characterized in that the hood portion has a front portion of the hood having a face opening formed therein for exposing the face of the patient, and a rear portion of the hood connected to the front portion of the hood and covering the area around the head portion of the patient, and the periphery of the hood portion that overlaps with the periphery of the cheek portion is inclined downward from the front portion of the hood toward the rear portion of the hood.
[0009] The automatic three-legged device related to the present disclosure is characterized in that, among the rear portions of the hood, the side opposite to the rotation axis portion with respect to the rear portion of the hood corresponds to a curved surface of a hemisphere with a diameter equal to the width of the left and right sides of the hood portion.
[0010] The automatic hair washing device related to the present disclosure is characterized by having a recessed portion formed on the rear portion of the main body, which is opposite to the front portion of the main body where the patient's body is placed, on the outer surface of the main body where the patient's leg is placed.
[0011] The automatic hair washing device related to the present disclosure is characterized in that, in the hood portion, a plate extending inward is formed on the side opposite to the face opening of the rotation axis portion among the two lower portions of the front portion of the hood.
[0012] The automatic three-legged device related to the present disclosure is characterized in that the plate extends toward the rear portion of the hood.
[0013] The automatic three-legged device related to the present disclosure is characterized in that the extended tip of the plate has a tapered end. Effects of the invention
[0014] The automatic hair washing device related to the present disclosure comprises a self-standing main body, a ball portion on which the head of a patient is positioned at the top of the main body, a hood portion covering the upper part of the ball portion, and a rotating shaft portion connecting the ball portion and the hood portion. The rotating shaft portion is positioned on the side of the patient's head portion positioned in the ball portion and faces the rear portion of the main body, which is opposite to the front portion of the main body, from the front portion of the main body where the patient's body is positioned, and is inclined downward from the front portion of the main body toward the rear portion of the main body. Because the rotating shaft portion is inclined, the rotational trajectory of the hood portion is also inclined. Therefore, when opening and closing the hood portion, the front portion of the hood traverses a position offset from the front of the patient's face toward the rear, so that even if a water drop attached to the inner surface of the hood portion falls off, it becomes difficult for it to reach the patient's face. Furthermore, as much as the hood portion is inclined, when a water drop flows along the inner surface or edge of the hood portion, it flows toward the rear portion of the hood, making it difficult for it to reach the patient's face.

Specific details for implementing the invention
[0016] The automatic hair washing device related to the present disclosure has a hood portion having a front portion of the hood with a face opening formed therein for exposing the face of the patient, and a rear portion of the hood connected to the front portion of the hood and covering the area around the head portion of the patient, wherein the periphery of the hood portion that overlaps with the periphery of the bowl portion is inclined downward from the front portion of the hood toward the rear portion of the hood. When a water droplet attached to the inner surface of the hood portion flows along the edge of the hood portion, it flows toward the rear portion of the hood, making it difficult to reach the face of the patient.
[0017] However, if the rotational axis is inclined and the rotational trajectory of the hood is inclined, the hood extends outward when opened, causing the hood to interfere with the operator performing treatment in the back position or with the wall located behind the automatic hair washing device. As described below, if a recessed portion is formed on the rear of the main body, the operator can move closer to the automatic hair washing device, causing the hood and the operator to interfere. Therefore, the automatic hair washing device related to the present disclosure has the rear of the hood, specifically the side opposite the rotational axis relative to the rear of the hood, configured to correspond to a curved surface of a hemisphere with the width of the left and right sides of the hood as its diameter. Consequently, when the hood is opened, the side opposite the rotational axis of the rear of the hood does not extend outward by the amount of the curved surface. Therefore, when the hood is opened, the hood and the operator do not interfere.
[0018] The automatic hair washing device related to the present disclosure has a recessed portion formed on the rear portion of the main body, which is opposite to the front portion of the main body where the patient's body is placed, on the outer surface of the main body, where the patient's legs are placed. In the back position, the patient can approach the patient by placing their legs into the recessed portion.
[0019] In the automatic hair washing device related to the present disclosure, a plate is formed extending inwardly on the side opposite to the face opening among the two lower portions of the front portion of the hood, at the periphery of the hood portion. Since water droplets attached to the inner surface of the hood portion flow along the plate, the water droplets can be directed away from the face of the patient. In addition, when the hood portion is closed and the automatic hair washing device is in operation, it is possible to suppress splashing water within the cheek portion from scattering through the gap in the front portion of the hood.
[0020] The automatic washing device related to the present disclosure has a plate extending toward the rear of the hood. Water droplets flowing along the plate can be made to flow toward the rear of the hood.
[0021] The automatic washing device related to the present disclosure has an extended tip of a plate that tapers at the end. Water droplets flowing along the plate can be directed toward the rear of the hood and can be appropriately guided toward the tip. If the plate is excessively large, the splash of water within the bowl when the hood is closed and the automatic washing device is in operation may be excessively obstructed, potentially hindering washing. However, since the plate tapers at the end, washing can be performed properly while suppressing splashing from the gap in the front of the hood.
[0022] Hereinafter, an automatic hair washing device related to an embodiment of the present disclosure will be described based on the drawings. FIGS. 1 to 6 show an automatic hair washing device (1) related to the present embodiment. In addition, below, the direction in which a patient (not shown) is lying is designated as the front side, the opposite side as the back side, the width direction when the front-to-back direction is the depth is designated as the right side, left side, respectively, and the height direction of the automatic hair washing device (1) is designated as the up side and down side, respectively (see FIG. 1).
[0023] As shown in FIGS. 1 to 6, the automatic hair washing device (1) has a main body (2) that stands on a surface for installation, a ball (3) on which the head of a patient is placed on the upper part of the main body (2), a hood (9) that covers the upper part of the ball (3), and a rotating shaft (25) connecting the ball (3) and the hood (9). The hood (9) is freely openable and closed, and in the closed state, the periphery (10) of the hood (9) overlaps with the periphery of the ball (3). A treatment space is formed on the inner side enclosed by the hood (9) and the ball (3).
[0024] Among the outer surfaces of the main body (2), a treatment table (not shown) is installed on the front side of the main body front part (4), and a patient lies on the treatment table. A concave shape (7) is formed on the upper part of the main body front part (4). The neck of the patient is placed in the concave shape (7). On the rear side of the main body rear part (5), which is opposite to the main body front part (4), a recessed part (8) is formed. The recessed part (8) is recessed from the rear side of the main body rear part (5) toward the inside of the main body (2). In the recessed part (8), when a patient (not shown) stands (or sits on a chair without a backrest) and performs treatment in the back position, the patient's legs are positioned. Among the outer surfaces of the main body (2), the upper surface of the main body upper part (6) is inclined downward as it faces the rear side.
[0025] When the neck of the patient is placed in the concave shape (7) of the front part (4) of the main body, the head of the patient is placed in the ball part (3). On the inner side of the ball part (3), a plurality of nozzles for ejecting hot water are installed, and a drain is formed (all are omitted from illustration).
[0026] The rotation axis portion (25) is positioned on the left side (right side when viewed from the lying patient) of the head portion of the patient positioned on the ball portion (3) in the upper surface portion (6) of the main body portion. Additionally, the rotation axis portion (25) is oriented in the front-rear direction, which is the longitudinal direction of the patient's face, and is inclined downward by an angle α with respect to the horizontal plane (26) from the front portion (4) of the main body portion toward the rear portion (5) of the main body portion.
[0027] Here, the hood portion (9) is described based on the drawings. Figures 7 to 12 show the hood portion (9).
[0028] As shown in FIGS. 7 to 12, the hood (9) is transparent or translucent and has a front hood portion (11) and a rear hood portion (12). The front hood portion (11) is in the shape of a semicircular plate and has a face opening (13) formed therein to expose the face of the patient. The face opening (13) is semicircular in shape. The rear hood portion (12) is connected to the circumferential edge (14) of the front hood portion (11) and is in the shape of a dome covering the area around the patient's head. The rear hood portion (12) has a right hood portion (15), a left hood portion (16), and a rear hood portion (17).
[0029] When viewed from the top, the hood rear curved portion (17) is asymmetrical (see FIG. 12). Specifically, the hood rear curved portion (17) has a hood left rear curved portion (30) which is on the left side and closer to the rotation axis portion (25), and a hood right rear curved portion (29) which is on the right side and opposite to the rotation axis portion (25) relative to the hood rear portion (12). The curvature of the hood right rear curved portion (29) is smaller than the curvature of the hood left rear curved portion (30). Therefore, the hood right rear curved portion (29) has a gentler degree of curvature than the hood left rear curved portion (30), and is less protruded toward the outside of the hood portion (9) than the hood left rear curved portion (30). For example, if the width in the left-right direction of the hood portion (9) is denoted as "A", the hood right rear curved portion (29) corresponds to a curved surface of a hemisphere with a diameter of "A". Also, when half of “A” is called “a”, the right rear curved portion (29) of the hood corresponds to approximately 1 / 4 of the curved surface of a hemisphere with a radius of “a”.
[0030] A hinge portion (18) is formed on the outer surface of the hood seat portion (16). The hinge portion (18) is a set of plate-shaped pieces (19) protruding outward, and the plate-shaped pieces (19) face each other. An axle hole (20) through which an axle member passes is formed in the plate-shaped piece (19). The axis line (27) passing through both axle holes (20) is inclined downward by an angle α with respect to the horizontal plane (26), just like the rotational axis portion (25), when the hood portion (9) is mounted on the main body portion (2) (see FIG. 5).
[0031] Among the main body (10) of the hood part (9), a set of left and right plates (21) extending toward the inner treatment space are formed at the lower part of the hood front part (11). The plates (21) have a rotational axis side plate (22) formed on the left side of the hood (16), which is the hinge part (18) side, and a non-rotational axis side plate (23) formed on the right side of the hood (15), which is the opposite side of the hinge part (18) to the facial opening (13). The non-rotational axis side plate (23) extends from the outer side of the hood front part (11) to the inner side and toward the rear part of the hood (12) relative to the hood front part (11). The front end (24) of the non-rotational axis side plate (23) tapers to a triangular shape.
[0032] The main edge (10) of the hood portion (9) is inclined downward from the front portion (11) of the hood toward the rear portion (12) of the hood. The main edge (10), the axis line (27) passing through the shaft holes (20) on both sides of the hinge portion (18), and the plates (22, 23) on both sides are generally parallel and are all inclined downward (see FIG. 11).
[0033] As described above, the automatic hair washing device (1) is configured. Next, the operation and effect of the automatic hair washing device (1) will be explained based on the drawings. Figures 13 to 21 show the hood (9) of the automatic hair washing device (1) in an open state.
[0034] After the procedure by the automatic hair washing device (1), as shown in FIGS. 13 to 15, the hood portion (9) opens toward the left with the left side as the axis of rotation (left turn in the same figures). As shown in FIGS. 16 to 18, since the axis of rotation (25) is inclined, the rotational trajectory of the hood portion (9) is also inclined. Specifically, in the side view, the right side portion of the hood portion (9) (the portion where the non-axis-side plate (23) is formed) of the hood portion (9) rotates in an arc in a direction that gradually falls from the vertical plane (28) that passes through the position where the hood portion (9) overlapped with the periphery of the ball portion (3) when the hood portion (9) was closed, accompanied by the rotation of the hood portion (9). Therefore, when opening and closing the hood portion (9), the front portion (11) of the hood crosses a position offset from the front of the patient's face toward the rear, so even if a drop of water attached to the inner surface of the hood portion (9) falls off, it becomes difficult for it to reach the patient's face. Also, as the hood portion (9) is inclined, the water drop flows toward the rear portion (12) of the hood when it flows along the inner surface or edge of the hood portion (9), making it difficult for it to reach the patient's face. Likewise, the periphery (10) of the hood portion (9) is also inclined from the front portion (11) of the hood toward the rear portion (12) of the hood, so the water drop flows toward the rear portion (12) of the hood, making it difficult for it to reach the patient's face.
[0035] In addition, since the upper surface (6) of the main body is inclined downward as it faces the rear, and the periphery (10) of the hood (9) is also inclined downward, a practitioner performing treatment in the back position can assume a posture that is easy to perform. That is, from the rear of the automatic hair washing device (1), as viewed from the practitioner, the upper surface (6) of the main body is lowered forward, so the practitioner can place their arm on the periphery of the cheek (3) and perform the treatment.
[0036] As shown in FIGS. 19 to 21, when the hood portion (9) is opened, water droplets attached to the inner surface of the hood portion (9) flow along the non-rotating axis side plate (23), so that the water droplets can be directed away from the face of the patient. On the other hand, when the hood portion (9) is closed and the automatic hair washing device (1) is in operation, the two plates (22, 23) are positioned between the ball portion (3) and the hood portion (9) (see FIG. 6), thereby suppressing the splash of water inside the ball portion (3) from scattering from the gap in the front portion (11) of the hood.
[0037] In particular, the non-rotating axis side plate (23) is formed on the right side opposite to the face opening (13) among the lower parts of the hood front part (11), and extends toward the hood rear part (12). Since the leading edge (24) of the non-rotating axis side plate (23), which is the extended front part, is tapered at the end and has a triangular shape, water droplets flowing along the non-rotating axis side plate (23) can be directed toward the hood rear part (12) and can also be properly guided toward the leading edge (24). In addition, since the non-rotating axis side plate (23) has a tapered end, it is possible to properly wash water droplets while suppressing scattering from the gap of the hood front part (11).
[0038] A recessed portion (8) is formed on the rear portion (5) of the main body of the automatic hair washing device (1), and when the operator performs treatment in the back position, the legs are positioned in the recessed portion (8). Thus, the operator can approach the patient. In addition, the operator can stand on the right side of the main body (2) and handle the patient's head.
[0039] As shown in FIG. 21, when the hood part (9) is fully extended, the extent to which the periphery (10) of the hood rear part (12) extends further back than the rear part (5) of the main body part (2) is slight. Therefore, the opening and closing hood part (9) can be prevented from interfering with the practitioner performing the treatment in the back position, and the automatic hair washing device (1) can be installed as close to the wall as possible. In other words, since the right rear curved surface (29) of the hood rear part (12) is a predetermined curved surface, the extent to which the hood part (9) extends outward is such that the hood part (9) does not touch the practitioner performing the treatment in the back position or the wall located behind the automatic hair washing device. Also, the angle α at which the rotation axis part (25) is inclined is such that when the automatic hair washing device (1) is installed next to the wall and the hood part (9) is extended, the hood part (9) does not touch the practitioner or the wall. In addition, the larger the angle α, the greater the degree to which the front part of the hood (11) deviates from the front of the patient's face to the rear when the hood part (9) is opened or closed, but the hood part (9) interferes with the patient or the wall on the rotational trajectory of the hood part (9).
[0040] In addition, in another embodiment of the present disclosure, the rotating shaft portion is inclined, but the periphery of the hood portion is horizontal.
[0041] In another embodiment, the shape of the hood is symmetrical.
[0042] In another embodiment, a recessed portion is not formed in the main body.
[0043] In another embodiment, the shape of the plate is arbitrary.
[0044] In another embodiment, the tip of the plate is not tapered.
[0045] In another embodiment, the hood part does not have a plate.
[0046] In another embodiment, the hood portion has only a non-rotating axis-side plate and does not have a rotating axis-side plate.
[0047] In another embodiment, the tip of the plate on the rotation axis side of the hood part tapers.
[0048] In another embodiment, the rotation axis is formed on the right side.
[0049] Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments. Furthermore, the present disclosure allows for various design modifications without departing from the matters described in the claims. Explanation of the symbols
