DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] In the foam generating method according to the present disclosure, in the water discharge step, cleaning water is applied to the inner surface to which the cleaning agent is applied and the vicinity thereof, and then the shower head is rotated inside the shampoo bowl. Turning Includes instructions. Turning By going through this procedure, the entire washing water in which the detergent is dissolved in the shampoo bowl is further stirred and foamed by the washing water discharged from the shower head. Therefore, regardless of the skill level of the user, it is possible to generate high-quality foam for cleansing.

[0013] The foam generating method according to the present disclosure includes a procedure for keeping the water discharge surface close to the water surface in accordance with the rise in the water level of the washing water stored in the shampoo bowl during the water discharge procedure. Even if the water level rises, the washing water continues to be discharged close to the water surface, so more foam is generated. Therefore, regardless of the skill of the user, it is possible to generate high-quality foam for cleansing.

[0014] The foam generating method according to the present disclosure includes a foaming step in which foam water generated through a foaming member of a shower head is used as cleaning water in the water discharge step. By using the foam water as cleaning water, finer foam is generated. Therefore, regardless of the skill of the user, it is possible to generate high-quality foam for cleansing.

[0015] The following is an explanation of a foam generating method according to an embodiment of the present disclosure and a hairdressing and beauty device 1 used in the method. Fig. 1 shows a hairdressing and beauty device 1 for carrying out the foam generating method according to the present embodiment. Fig. 2 shows a shampoo bowl 10 used in the hairdressing and beauty device 1.

[0016] As shown in Figure 1, the hairdressing and beauty device 1 comprises a treatment table 2 used by a person to be treated (not shown), a shampoo bowl 10 positioned behind the treatment table 2 on which the head of the person to be treated is placed, a shower head 13 provided on the shampoo bowl 10, and a multiphase flow generating device (not shown) that generates wash water by mixing a multiphase flow with the hot and cold water discharged from the shower head 13.

[0017] The treatment table 2 has a seat section 3 on which the person to be treated lies, and a lifting section 4 that supports the seat section 3 from below. The seat section 3 has a seat section 5 on which the person to be treated sits, a leg rest section 6 connected to the front of the seat section 5 and on which the legs of the person to be treated are placed, a backrest section 7 connected to the rear of the seat section 5 and on which the upper body of the person to be treated is placed, and an armrest section 8 arranged on the left and right sides of the seat section 5 and on which the arms of the person to be treated are placed. The treatment table 2 has a lifting section 4 that operates to expand and contract up and down, so that the seat section 3 rises and falls, and the backrest section 7 falls or rises, so that the angle of the seat section 3 changes. When the backrest section 7 falls, the seat section 3 becomes horizontal or approximately horizontal. The posture of the treatment table 2 can be changed arbitrarily by the therapist (not shown) or automatically to a predetermined posture.

[0018] The shampoo bowl 10 is for the person to place his / her head while lying on his / her back on the seat part 3 and receive the treatment. The therapist stands behind or to the side of the shampoo bowl 10 (or sits on a stool) and performs a treatment on the head and hair of the person to be treated. The treatment may include, for example, shampoo, scalp massage, hair coloring, permanent wave, hair treatment, eye makeup, etc. The shampoo bowl 10 is placed on the base part 9.

[0019] The multiphase flow generating device turns hot water into a multiphase flow by incorporating air into the hot water discharged from the shower head 13, and is therefore connected to one of the hot water flow paths. For example, it is built into a hot water supply unit (not shown) that sends out hot water or into the base unit 9, or is connected to the hot water supply unit or base unit 9 via piping from the outside. In addition, a switch (not shown) that selects whether or not to operate the multiphase flow generating device is installed near the base unit 9.

[0020] As shown in Fig. 2, shampoo bowl 10 is composed of bottom 14 and peripheral wall 15, and is generally hemispherical. In shampoo bowl 10, bottom 14 is formed with drain port 11, and the inner surface of peripheral wall 15 is provided with hot and cold water stop valve 12, shower head 13 for discharging hot and cold water, etc. A portion of peripheral wall 15 facing seat portion 3 is recessed, and head support device 16 is attached thereto. Head support device 16 can be freely attached and detached. The neck and head of the person to be treated are placed on head support device 16.

[0021] Next, the showerhead 13 will be described in detail with reference to the drawings. 3 to 9 show the appearance and cross section of the showerhead 13.

[0022] 3 to 9, shower head 13 has a hose connection part 20 to which a shower hose (not shown) is connected, a head main body part 21 connected to the downstream side of hot and cold water at hose connection part 20, and a water outlet part 22 formed on the downstream side of head main body part 21. Hot and cold water that flows through the shower hose flows through hose connection part 20 and head main body part 21 in that order, and is discharged from water outlet surface 23 of water outlet part 22.

[0023] The head body 21 is generally cylindrical, and has a flow path switching unit 28 for switching the flow path of hot and cold water discharged from the water discharge unit 22, and two inflow chambers into which the hot and cold water whose flow path has been switched by the flow path switching unit 28 flows inside the head body 21. The flow path switching unit 28 switches the flow path of the hot and cold water by moving a valve. The flow path switching unit 28 has a switch 29 for switching the flow path, and the switch 29 protrudes from the flow path switching unit 28 to the outside of the head body 21. One of the inflow chambers is a cylindrical central flow path 30 located at the center of the head body 21, and the other of the inflow chambers is a circular peripheral flow path 31 located on the outer periphery of the central flow path 30. A foaming member 32 is attached to the central flow path 30. The hot and cold water that has passed through the foaming member 32 contains a large amount of air bubbles.

[0024] The water spouting surface 23 formed at the tip of the water spouting section 22 is circular, and has multiple water spouting holes 24 formed therein. The water spouting surface 23 has a circular central water spouting surface 25 at the center of the water spouting surface 23, and a ring-shaped peripheral water spouting surface 26 at the outer periphery of the central water spouting surface 25. The central water spouting surface 25 is located downstream of the central flow path 30 of the head main body 21, and is formed by the downstream end face of the foaming member 32. The peripheral water spouting surface 26 is located downstream of the peripheral flow path 31 of the head main body 21.

[0025] At the front end of the water spouting section 22, the peripheral portion 27 of the water spouting surface 23 protrudes in the water spouting direction further than the outer peripheral water spouting surface 26. Therefore, the outer peripheral water spouting surface 26 is recessed in the opposite direction to the water spouting direction. The central water spouting surface 25 does not protrude from, nor is it recessed into, the peripheral portion 27. Therefore, the central water spouting surface 25 protrudes in the water spouting direction further than the outer peripheral water spouting surface 26, just like the peripheral portion 27. With this configuration, an emulsification promotion space 33 is formed in front of the water spouting surface 23 as a space formed by the water spouting surface 23 and the peripheral portion 27.

[0026] A plurality of protrusions 34 are formed on the outer surface of the shower head 13, that is, on the outer peripheral surface of the water discharger 22. The protrusions 34 are arranged at equal or approximately equal intervals along the outer peripheral direction of the water discharger 22. The protrusions 34 gradually rise outward from the tip edge 35 of the peripheral portion 27 toward the opposite side of the water discharge direction. The apex 37, which is the tip of the raised portion 36, is a stripe extending toward the outer peripheral direction of the water discharger 22. The apex 37 is located 0.5 to 1.5 mm away from the tip edge 35 of the peripheral portion 27 toward the opposite side of the water discharge direction (see interval 38 in FIG. 6). A groove 39 is formed in the apex 37. The groove 39 is recessed from the outside toward the inside and extends toward the outer peripheral direction of the water discharger 22. One end of the groove 39 is open, and the other end is closed.

[0027] The beauty salon apparatus 1 is configured as described above. Next, an emulsification method using the beauty salon apparatus 1 will be described with reference to the drawings, along with the action and effect of the beauty salon apparatus 1. FIG. 10 shows how the shower head 13 is held by the person to be treated in the emulsification method. After performing a treatment such as hair coloring, the practitioner uses the emulsification method to wash away the chemicals attached to the hair of the person to be treated. The hot and cold water used in the emulsification method may be either that discharged from the central water discharge surface 25 or that discharged from the outer peripheral flow path 31 (hereinafter, the hot and cold water discharged from the central water discharge surface 25 will be referred to as "foam water", the hot and cold water discharged from the outer peripheral water discharge surface 26 will be referred to as "spray water", and the hot and cold water or spray water will be referred to as "hot and cold water").

[0028] As shown in FIG. 10, first, the practitioner grasps the outer surface of the shower head 13 so as to cover the outer peripheral surface of the water discharger 22 from the head body 21 side. For example, the practitioner places the first joint of the finger 17 or its vicinity against the apex 37 of the protrusion 34, causing the finger 17 to protrude from the water discharge surface 23 toward the water discharge direction. Therefore, the practitioner can use his / her fingertips while holding the shower head 13, and can perform treatment with the finger 17 holding the shower head 13. In addition, multiple fingers 17 are caught on the protrusions 34, and the shower head 13 is held at equal intervals, so the hands are less likely to slip. In particular, the apex 37 of the protrusion 34 is horizontally long along the outer peripheral direction of the water discharger 22, and rises gently from the tip edge 35 of the peripheral portion 27 (see FIG. 4, etc.), so that the first joint of the finger 17 is easily caught.

[0029] In this position, fingers 17 protruding in the water discharge direction are placed against the hair with a gap between water discharge surface 23 and the recipient's hair, and water discharge surface 23 is brought close to the hair. This creates an appropriate gap between water discharge surface 23 and the hair, and an emulsification-promoting space 33 is naturally formed between the hair and water discharge surface 23. Here, emulsification-promoting space 33 is not only the space formed by water discharge surface 23 and peripheral portion 27, but also includes this space and is the space between the hair in front of water discharge surface 23.

[0030] During these steps, the stop valve 12 is turned as appropriate to discharge hot and cold water. In addition, before and after discharging hot and cold water, the multiphase flow generating device is operated. When the multiphase flow generating device is operated, the hot and cold water that has become a multiphase flow due to the inclusion of air is pressurized by the pump of the multiphase flow generating device and is forcefully discharged from the water discharge surface 23 (hereinafter, the multiphase flow hot and cold water will be referred to as "washing water").

[0031] The cleaning water discharged from the water discharge surface 23 hits the hair of the person to be treated and bounces back towards the water discharge surface 23. The cleaning water swirls between the water discharge surface 23 and the hair, entraining air, and is instantly received by the water discharge surface 23 and retained in the emulsification promotion space 33. When the oil of the medicine attached to the hair mixes with the cleaning water, the interface is activated and emulsification occurs. In the emulsification promotion space 33, the cleaning water hits the hair and retains there, so that appropriate emulsification can be easily caused in a short time. In addition, when the water discharge surface 23 approaches the hair, the cleaning water reaches the roots of the dense hair, so that emulsification can be caused up to the roots of the hair. Therefore, emulsification can be caused throughout the entire hair or within a desired range without unevenness.

[0032] Next, a foam generating method using the beauty device 1 will be described with reference to FIG. 2. The foam generating method includes at least a plugging step, an application step, and a water discharge step. In the water discharge step, as necessary, Turning It goes through the procedure, the proximity procedure and the foam procedure.

[0033] In FIG. 2, in the plugging step, a plug is attached to drain outlet 11 to close drain outlet 11. This makes shampoo bowl 10 ready to be filled with hot water and foam. In the application step, a detergent such as shampoo is applied to the inner surface of shampoo bowl 10. The amount of detergent applied is arbitrary, but if the detergent container is a pump bottle, for example, the amount is about the amount that is discharged by pushing the nozzle two to three times. The position where the detergent is applied is also arbitrary, but for example, it is near drain outlet 11 on bottom 14. The plugging step and the application step may be performed in the reverse order.

[0034] After the closing procedure and the application procedure, in the water discharge procedure, the water discharge surface 23 of the shower head 13 is brought close to the bottom 14 of the shampoo bowl 10, directly above the applied detergent, or close to the detergent. The switch 29 of the shower head 13 is operated to select water spray or foaming water. When the multiphase flow generator is operated and the stop valve 12 is operated (or the stop valve 12 is operated and the multiphase flow generator is operated), cleaning water is discharged from the shower head 13. When the cleaning water hits the detergent or its vicinity inside the shampoo bowl 10, the detergent dissolves and mixes with the cleaning water, gradually foaming, and fine bubbles are generated. Turning In this procedure, after the cleaning water hits the detergent or its vicinity, the shower head 13 is rotated inside the shampoo bowl 10 while discharging the cleaning water. The cleaning water and detergent are mixed, and air is further mixed and stirred, gradually increasing the amount of foam. As the level of the cleaning water accumulated in the shampoo bowl 10 rises, the water discharge surface 23 is kept close to the water surface in response. The distance between the water surface and the water discharge surface 23 is about several millimeters to several centimeters.

[0035] In this way, a large amount of cleansing foam is generated in the shampoo bowl 10. The detergent foams further as it is stirred by the wash water, and further foams as the wash water continues to hit it close to the water surface. In particular, when wash water made of foam water is used, the foaming step generates even finer foam.

[0036] As described above, the foam generating method can generate high-quality foam for cleansing, regardless of the skill of the practitioner. The high-quality foam completely covers the surface of the washing water stored in the shampoo bowl 10, and is layered so thickly that the surface of the water cannot be seen. Even if the practitioner scoops up the foam with his / her hand and tilts it, the foam does not fall off the hand and does not disappear for a while.

[0037] In other embodiments of the present disclosure, the showerhead does not have any protrusions on its outer surface. In another embodiment, the central spouting surface is recessed on the side opposite the spouting direction, similar to the peripheral spouting surface. In other embodiments, the shape, number, arrangement, etc. of the protrusions are arbitrary. In another embodiment, the beauty salon device may have any configuration. In another embodiment, Turning No procedures are followed. In other alternative embodiments, no proximity procedure is performed. In other alternative embodiments, no foaming step is performed.

[0038] Although the embodiments of the present disclosure have been described in detail above, the present disclosure is not limited to the above-described embodiments. Various design modifications can be made to the present disclosure without departing from the scope of the claims. [Explanation of symbols]
