[Industrial applications]

 The present invention relates to an automatic hair washing machine for washing hair by automatically discharging shampoo or washing water.

[0002]

[Prior art]

 Conventionally, an automatic hair washing machine has been used, in which shampoo and washing water are applied to the hair at different timings to wash the hair automatically. The basis of this automatic hair washing machine is to equip a ball that is large enough to receive its head when a person is lying on his back, and to automatically feed washing water or shampoo liquid to this ball. is there.

For example, in Japanese Patent Publication No. 63-201222, a ball is equipped with a nozzle for discharging hot water or shampoo liquid, and a ball drain is equipped with an electromagnetic valve for opening and closing to collect hot water in the ball to wash hair. A hair washer made in this way is described. With this hair washing machine, the nozzles are positioned so that the washing water, shampoo, etc. are properly applied to the hair, and the washing water can be discharged not only to the back of the head but also to the front of the head and face. ing.

[0004]

[Problems to be solved by the device]

 In the case of washing hair using an automatic hair washing machine, the nozzles and shower heads for spraying washing water and shampoo are fixed, so the range of spraying and discharging washing water and shampoo is limited to some extent. On the other hand, since a large number of nozzles and showers can be installed on the bottom of the ball for the back of the head, washing water and shampoo can be bathed in the hair evenly, and sufficient washing is possible.

On the other hand, for the hair of the forehead, the nozzle is arranged above or obliquely above the head, and washing water or shampoo is applied from above. However, since the head is placed on the ball to wash the hair, it is impossible to dispose a nozzle fixed on the upper side of the head, and there is no choice but to dispose the nozzle on the top side of the head.

On the other hand, there are short hairs like men's hair and long hairs like women's hair, and in the case of short hairs, a nozzle for discharging washing water toward the forehead is fixed. However, it can be cleaned to some extent. However, for long hair, the fixed nozzle can only partially wash the hair with washing water, which results in insufficient washing. Therefore, it is necessary to newly install a nozzle for long hair and the like, which complicates the piping and causes an obstacle that the capacity of the ball must be increased.

The problem to be solved in the present invention is to enable an automatic hair washing machine to properly wash short hair and long hair by appropriately spraying washing water with a single discharge part.

 FIG. 1 is a front view showing an embodiment of an automatic hair washer of the present invention, and FIGS. 2 (a) and 2 (b) are a plan view and a right side view of an upper end portion thereof.

In the figure, a ball 1 having a shape that receives the head of the person when the person is in a supine posture is integrated with the upper end of a floor-standing housing 2. The ball 1 is large enough to receive a human head, and a cover 1a for receiving the human head is provided on the upper surface of the ball 1 so as to be openable and closable. Then, an opening 1b is opened in the cover 1a, a pad 1c made of rubber or the like is attached to the opening edge, and the front hair is dropped into the pad 1c so that the hair portion is inside the ball 1. To face.

Inside the housing 2, hot and cold water mixing taps for mixing hot water and water to the ball 1 and various valve units are arranged, and a pipe structure capable of supplying shampoo, rinse, etc. by another system is incorporated, It is assumed that the drainage route from the ball 1 is connected to the building piping. The operation of supplying water, supplying hot water, stopping the supply of shampoo, rinse, and the like through these piping systems is performed by the operation panel 1d provided on the rim portion of the ball 1.

FIG. 3 is a plan view of the ball 1 excluding the cover 1a, and FIGS. 4 and 5 are vertical sectional views taken along the lines AA and BB of FIG. 3, respectively.

The bottom of the ball 1 on the back side is deepened to open a drain port 1 e at the lower end thereof, and this is connected to a drain pipe (not shown) in the housing 2. A hand shower 1f is provided on the upper surface of the ball 1 and near the operation panel 1d. The hand shower 1f has a hose (not shown) connected to the base end thereof housed in the housing 2, and can be pulled out and used as needed.

A plurality of shower heads 3 and a nose head 4 for shampoo and rinse are installed on the inner wall of the ball 1, and a shower head 5 for the frontal region and the crown is provided at the upper end of the rear part. The shower heads 3 and 5 are respectively connected to the flow paths to the hot and cold water mixing taps inside the housing 2, and hot water and water are supplied independently by appropriately controlling the opening and closing of the solenoid valve incorporated in the piping system. . Further, the nozzle head 4 is connected to a shampoo or rinse tank with a separate flow path, and a shampoo or rinse can be selected and supplied by a solenoid valve.

The shower head 3 can spray hot water or water in the same manner as a normal shower, and the nozzle head 4 has a structure capable of spraying shampoo or rinse toward the head with an appropriate spray pressure.

On the other hand, the shower head 5 for the forehead and the crown is arranged on the ball 1 by lying sideways as shown in FIG. 4, and FIG. 6 shows a cross-sectional view thereof.

The shower head 5 includes an inner cylinder 6 whose one end is connected to a water supply pipe 5 a fixed to the ball 1 and an outer cylinder 7 coaxially arranged around the water supply pipe 5 a. It is rotatable around the axis.

One end of the inner cylinder 6 in the axial direction is connected to the water supply pipe 5a, and a plurality of holes 6a are opened in the peripheral wall to connect the flow path from the water supply pipe 5a to the outer cylinder 7.

The outer cylinder 7 is connected to the inner cylinder 6 in a watertight manner and is rotatable about its axis. As shown in the vertical sectional view of FIG. The water spray holes 9 and 10 of the two groups thus formed are opened. These water sprinkling holes 9 and 10 are included in the cut surfaces 9a and 10a in which the surface of the outer cylinder 7 is partially flat, and are opened in the same pattern arrangement. The central angles formed by the axes of the water spray holes 9 and 10 included in these two cut surfaces 9a and 10a are set to values smaller than 90 °, and the respective directions are made different.

As described above, due to the difference in the directions of the opening axis lines of the water spray holes 9 and 10 divided into the two groups, two water sprays having different discharge directions are simultaneously discharged from the outer cylinder 7. Then, by changing the posture of the outer cylinder 7 of FIG. 7A to the posture of FIG. 7B, the water spraying direction can be tilted slightly obliquely upward, and the water spraying direction can be changed up and down. .

The motor 8 is fixed to the end surface of the water supply pipe 5 a, and its rotation output spindle 8 a penetrates the inner cylinder 6 and is connected to the end of the outer cylinder 7. This spindle 8a is integrated with the outer cylinder 7 by a screw 8b screwed from the peripheral surface of the outer cylinder 7, and the outer cylinder 7 is also rotated by the rotation of the spindle 8a, thereby changing the postures of the cut surfaces 9a, 10a. The direction of water spray from the water spray holes 9 and 10 can be changed.

When the screw 8b is screwed into the end portion of the outer cylinder 7 as a knob 7a and the motor 8 is not operated, the outer cylinder 7 can be manually rotated by rotating the knob 7a. To do. For this purpose, an appropriate clutch mechanism or the like may be provided in the drive system of the motor 8 so that the spindle 8a can be freely rotated. Then, when the manual operation is performed by the knob 7a, it is set in advance so that an appropriate sprinkling direction is set so that the operator can operate by inserting his / her hand through the opening 1b of the cover 1a.

FIG. 8 is a schematic diagram of a control block for controlling the rotation operation of the outer cylinder 7 by the motor 8.

The motor 8 is operated by an operation switch 1d-1 arranged on the operation panel 1d for stop, forward rotation, reverse rotation, etc., and the controller 8 is energized by the control unit 11 according to the operation switch 1d-1. Is controlled. Then, as shown in the flow chart of the control unit 11 in FIG. 9, if one of the operation switches 1d-1 that rotates in the forward direction is turned on, the water spray from the water spray holes 9 and 10 is directed outward. The motor 8 is energized so that the cylinder 7 rotates. When the reverse rotation type is turned on, the energization of the motor 8 is controlled so that the outer cylinder 7 is rotated so that the water spraying direction is downward.

The rotation angle based on the posture at the stop position during forward rotation and reverse rotation is set to a constant value corresponding to one pulse as shown in the flow chart of FIG. 9, or the operation switch 1d-1 is pressed. It is optional to increase the rotation angle in proportion to the time during which the rotation is performed. Further, when the stop operation switch 1d-1 is turned on, the outer cylinder 7 is rotated and stopped so as to return to the original reference position.

Further, before using the shower head 5 for the forehead, a piping system capable of supplying trial hot water for checking whether the discharged hot water appropriately hits the head is assembled. For example, as such a piping system, a branch pipe to the shower head 5 is connected to the most upstream side of the flow path from the hot and cold water mixing tap for supplying hot water, and an electromagnetic on-off valve is incorporated in this branch pipe. Good. A trial hot water switch 1d-2 for operating the electromagnetic open / close valve is provided on the operation panel 1d, and the electromagnetic open / close valve is opened when the trial hot water switch 1d-2 is pressed.

By providing such a piping system, it is possible to determine whether or not the hot water is properly hitting the head by discharging hot water from the shower head 5 and pouring it on the head before the main cleaning. Therefore, if the trial hot water is used to determine whether the shower head 5 is to be directed upward or downward, and the operation switch 1d-1 is used to adjust the orientation of the shower head 5, the comfortable cleaning can be performed. .

In the above-described configuration, when the initial cleaning is wet, hot water is discharged from the shower heads 3 and 5 to wet the hair, and then the shampoo liquid is discharged from the nozzle head 4 for shampooing. Then, when rinsing, the hot water is again discharged from the shower heads 3 and 5 to wash away the hair. It is needless to say that the supply of such hot water, water, shampoo, rinse, etc. is controlled by controlling the operation of the electromagnetic on-off valve arranged in the flow path system with a timing.

Here, the outer cylinder 7 of the shower head 5, which is on the back side of the ball 1 and at a higher level than the frontal region of the person lying on his back, can be rotated around its axis by the motor 8. . That is, when the forward rotation switch of the operation switch 1d-1 is turned on, the outer cylinder 7 rotates as shown in FIG. 7A to FIG. 7B, and the reverse rotation switch is turned on. The outer cylinder 7 rotates from the position shown in FIG. Therefore, the direction of water spray from the water spray holes 9 and 10 divided into two groups can be changed, and even with short hair or long hair, by adjusting the direction of water spray, unwashed residue or unrinsed residue is generated. You can wash your hair without

For example, as shown in FIG. 7A, if the opening axes of the water spray holes 9 and 10 of the second group are both directed obliquely downward, the amount of wash water hitting from the frontal region to the crown is relatively small. Become Therefore, in the case of washing the hair of a person with short hair, the washing water can be thoroughly washed without wasting the washing water. Further, as shown in FIG. 7B, when the directions of the water spray holes 9 and 10 are slightly tilted upward, the amount of wash water discharged from the frontal region to the crown is increased. Therefore, it is suitable for washing hair when the hair is long and has a large volume, and can be sufficiently rinsed.

Further, since the angle of the outer cylinder 7 can be adjusted by using the operation panel 1d provided outside the cover 1a, the most suitable sprinkling hole according to the condition of the head hair of the person washing the hair. Angles of 9 and 10 can be set. If not only the angle setting but also the system of the control unit 11 is configured so that the output shaft of the motor 8 reciprocally rotates, the outer cylinder 7 reciprocates between the postures of FIGS. 7 (a) and 7 (b). It can be taken while exercising, and the washing water can be poured on the hair while rocking the water spray from the water spray holes 9, 10 up and down. Therefore, it is possible not only to apply the washing water to the hair but also to improve the washing power by the movement of the stream line of the washing water, which enables efficient rinsing.

Further, when the motor 8 is not used, the posture of the outer cylinder 7 may be appropriately set by inserting the hand through the opening 1b of the cover 1a and operating the knob 7a. It is possible to spray water that matches the hair on the frontal part of the head.

As described above, by simply changing the direction of the shower head 5 for the forehead, it is possible to obtain watering suitable for each of short and long hairs. Therefore, it is not necessary to separately provide a shower head for short hair and a shower head for long hair, and it is not necessary to increase the capacity of the ball 1 or add piping.

Further, prior to the main cleaning, the orientation of the shower head 5 is changed by the operation switch 1d-1 by checking whether the hot water is properly hitting the head by the trial hot water switch 1d-2. It is possible to inject the hot water for washing that is optimal for the posture and hair condition. Even if the trial hot water switch 1d-2 is not used, the operator can put the arm through the opening 1b of the cover 1a and turn the knob 7a to adjust the direction of the shower head 5.

[0042]

[Effect of device]

 In the present invention, the direction of water spray from the shower head that showers the wash water from the frontal region to the crown can be swung up and down, so even for people with short or long hair, simply change the direction of water spray. Optimal cleaning and rinsing can be performed.

Also, since one shower head can be used for both short hair and long hair, the piping space can be reduced and the ball capacity can be secured, and the device can be made compact.

Further, if the drive system is controlled by the control unit and the sprinkling direction is changed continuously in the vertical direction, the swaying movement of the washing water can be used to improve the washing effect. Appropriate cleaning can also be performed by changing the direction of water spraying.

Further, since the trial hot water is discharged from the shower head prior to the main washing, the shower head can be set in an appropriate direction after the trial hot water, and optimal washing can be performed.
