Abstract

PURPOSE:To prevent leakage of cleaning water or the like even when a person's head part shallowly enters a bowl part by continuously arranging face packing to fixing tools inserted and passed in guide holes which are bored in a cover and turn in the longitudinal direction. CONSTITUTION:When hairs are washed, a head part is situated in a bowl 1a in a condition where a person lies with face up on a chair set on this side of a main body 1. A cover 2 is closed, and a part up to the vicinity of jaws from a forehead is covered with packing 3. Here, if the face packing 3 is dislocated to the head part side to a face since entrance of the head part into a bowl part 1a is insufficient, the face packing 3 is moved to the front side. This work is performed in such a way that knob parts 8a of fixing tools 8 are rotated and a screw-fitting degree to nuts 8 is weakened and several pieces of the fixing tools 8 are simultaneously pushed forward. Thereby, bolts of the fixing tools 8 are guided by guide holes 2a of the cover 2, and the face packing 3 is moved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic hair washing machine that can automatically wash and wash hair with a shampoo solution.
Particularly, it relates to a structure around a face packing for preventing water from splashing on a person's face.

[0002]

2. Description of the Related Art An automatic hair washer has been conventionally used which is capable of automatically washing the hair by applying a shampoo or washing water to the hair at a set timing. This automatic hair washing machine has a hair-washing ball of a size that receives the head of a person when the person is lying on his / her back, and has a basic structure for automatically ejecting washing water or shampoo liquid into the hair-washing ball.

In such an automatic hair washing machine, it is necessary to prevent the washing water from leaking to the outside and splashing on the human face. For example, Japanese Utility Model Application Laid-Open No. 55-95603 proposes a cover provided with a face packing in which only a person's head is desired to be a hair-washing ball and only a face is exposed. This face packing has a shape that fits the contour of the face from the hairline to the chin, and prevents wash water and shampoo from leaking out and adhering to the face.

[0004]

However, the cover has an opening through which a person's head can be dropped to the side of the hair-washing ball. However, this is only for opening the hair-washing ball in the vertical direction and closing it. The position is fixed when raised. For this reason, when a person sleeps on his / her back and drops his / her head into the opening to cover the face packing, the degree of adhesion of the face packing may be weakened by adjusting the position of the head. For example, if the head does not come close enough to the opening side, the edge of the face packing against the forehead or the like only hits loosely and the seal becomes defective.

As described above, if the seal is not good, it is necessary to shift the body while the person is lying on his back and try again, which is difficult to use.

Further, the face packing is often made of a flat rubber plate, and even if its thickness is increased, its waist is weak and its edge only covers the face. For this reason, if the washing water with strong force hits between the edge of the face packing and the surface of the face, there is a risk that it will penetrate the seal portion, and the face may be exposed to water or shampoo.

The problem to be solved in the present invention is that even if the position of the head is not appropriate, the head can be absorbed to obtain a good seal, and the sealing force is further enhanced to ensure the leakage of cleaning water and the like. To prevent it.

[0008]

According to the present invention, there is provided a ball portion capable of accommodating a person's head, a means provided inside the ball portion for injecting cleaning water, etc. In an automatic hair washing machine equipped with a cover having a shape that only exposes a person's face to the outside, and a face packing that is connected to the cover and covers from the person's forehead to the chin, the face packing is opened at the tip side. A plurality of guide holes are formed in the cover in the shape of an inverted U shape and have a long axis having a major axis in the front-rear direction. The guide holes are inserted to restrain the face packing and the guide holes. And a posture in which the long axis of the guide hole is oriented toward the tip side of the cover and inclined toward the center side in the width direction.

Also, on the upper surface and the lower surface of the face packing,
Two pressing plates each having a shape along a part of the sealing surface at the edge of the face packing may be provided, and the pressing plates may be connected to the fixture and joined to the face packing.

Further, the skirt is bent downward at a portion along the inverted U-shaped edge on the front end side of the face packing and the lower end thereof is bent inward to form a pressing surface that comes into close contact with a person's forehead. It is also possible to form a guard projecting downward at a position on the back side along the skirt.

[0011]

[Function] Since the face packing is connected to the fixing tool that is inserted through the guide hole that is opened in the cover and extends substantially in the front-rear direction, the face packing can move back and forth with respect to the cover in a fixed position, and the head of the person In the case where is shallowly inserted in the ball portion, the face packing can be moved forward to secure the sealing surface.

Further, since the major axis of the guide hole is inclined toward the center in the width direction of the cover, the face packing having an inverted U-shaped planar shape when the cover is extended to the front side is It can be deformed so that the width on the tip side is narrowed, and a sealing surface can be formed so as to wrap a human jaw.

Furthermore, since the upper and lower surfaces of the face packing are lined by the pressing plates, the face packing becomes stiff and a high sealing pressure can be obtained. Since these pressing plates are joined to the face packing by the fixing tool, they move integrally with the front and rear movements of the face packing, and the sealing pressure is always kept high.

Further, by making the lower end portion of the skirt a pressing surface which is bent inward, it is possible to reduce the pressing force applied to the forehead. By providing a guard behind this skirt, this guard can be used as a barrier against the injection of cleaning water, shampoo liquid, etc. Even if the skirt has a loose sealing pressure, it will not leak. Prevention is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view of an upper end portion of an automatic hair washer according to the present invention as seen obliquely from the front and from above.

In the figure, a ball portion 1a into which a person's head is dropped is provided at the upper end of a main body 1 of an automatic hair washing machine, and an inner peripheral wall of the ball portion 1a is provided with washing water, shampoo, rinse liquid, etc. Various nozzles 1b and a shower head 1c for ejecting the liquid are provided. These nozzles 1b
The shower head 1c and the like are connected to the same supply system of washing water as that proposed by the present applicant as Japanese Patent Application No. 4-61269, for example, and an appropriate hair washing is performed using the operation panel 1d at the upper end of the main body 1. Pattern control is possible.

A cover 2 is provided on the upper end of the main body 1 to cover the entire ball portion 1a. The cover 2 has its rear end connected to the main body 1 by a hinge mechanism, and can be opened by pulling up the front side in the drawing. Further, the cover 2 has a planar shape that is cut out in an inverted U shape when viewed from the front, and this cutout portion is gently inclined downward toward the center and the front side of the main body 1.

FIG. 2 is a plan view of the main part except the main body 1,
FIG. 3 is a vertical sectional view taken along the line AA of FIG.

On the lower side of the cover 2, a planar face packing 3 that follows the outline of the cutout is incorporated, and a total of four holding plates 4 to 7 sandwiching the upper and lower surfaces of the face packing 3 are provided.

The face packing 3 is made of a thin rubber plate, has a substantially inverted U-shaped planar shape, and has a total of five through holes 3a formed in the center and symmetrically.
An inverted U-shaped notch 3b is provided in the center of the front face, and a skirt 3c bent downward as shown in FIG. 3 is provided around the notch 3b, and the foaming sealing material 3d is integrally formed along the skirt 3c. It is attached. The foamable sealing material 3d has a length protruding below the lower end of the skirt 3c as shown in FIG.

FIG. 4 is a plan view showing a combination of the pair of pressing plates 4 and 5 to be put on the upper surface of the face packing 3.

These pressing plates 4 and 5 are made of an acrylic plate having a wall thickness of, for example, about 0.5 to 2 mm as a material, and are a combination of common parts which are symmetrical to each other. Then, these pressing plates 4 and 5 are provided with three through holes 4a to 4c and 5a to 5c, which are aligned with the through holes 3a of the face packing 3.

FIG. 5 is a bottom view showing the lower pressing plates 6 and 7 together with the face packing 3.

These pressing plates 6 and 7 are also common parts to the pressing plates 4 and 5 which are put on the face packing 3, and three through holes 6a to 6c and 7a to 3 are provided.
7c is opened.

On the other hand, the cover 2 is provided with five guide holes 2a as shown in FIG. These guide holes 2a are positioned so that they can be aligned with the through holes 4a to 7c of the holding plates 4 to 7, and each has an elongated opening shape.
The major axis of the guide hole 2a located at the center in the figure coincides with the center line of the face packing 3, and the major axis of each of the two guide holes 2a located on the left and right is the face packing 3.
Is directed inward so that it intersects with the center line at the tip side.

As shown in FIG. 3, the face packing 3 and the four holding plates 4 to 7 are fixedly held on the cover 2 by the fixing tool 8. The fixture 8 includes a bolt 8b whose upper end is a knob 8a, a nut 8c screwed to the bolt 8b,
A seal washer 8d and a spring washer 8e mounted on the nut 8c side are provided, and a washer 8f is provided on the knob portion 8a side.

With the above constitution, when washing hair,
The head is positioned in the ball 1a with a person lying on his / her back in a chair set in front of the main body 1. Then, the cover 2 is closed as shown in FIG. 3, and the face packing 3
Cover from forehead to near chin with. Although FIG. 3 shows only the foamable sealant 3d in close contact with the human face, the foamable sealant 3d has a crushed shape due to the weight of the cover 2 and the like, and the cutout portion of the face packing 3 is formed. The entire edge around 3b is in close contact with the face.

Here, if the head part 3 is not sufficiently inserted into the ball part 1a and the face packing 3 is largely displaced to the head side with respect to the face, the face packing 3 is moved to the front side. . This operation is performed in such a manner that the knob 8a of the fixture 8 is turned to weaken the degree of screwing with the nut 8c and some of the fixtures 8 are simultaneously pushed forward. As a result, the bolt 8b of the fixture 8 is guided by the guide hole 2a of the cover 2, and the entire face packing 3 is moved forward together with the holding plates 4-7.

As shown in FIG. 2, the long axes of the long guide holes 2a are oriented in the direction of the center line of the cover 2, so that the face packing 3 moves forward. It deforms so that it becomes narrower in the width direction. at the same time,
The four pressing plates 4 to 7, which are restricted by only one point by the bolt 8b, change their postures in the directions of the arrows in FIGS. 4 and 5 and follow the movement of the face packing 3.

Due to the movement and deformation of the face packing 3 as described above, even if the head is too biased forward with respect to the position of the face packing 3 shown in FIG. 2, it is possible to seal the face tightly. Therefore, it is not necessary for a person who has once slept on the chair to shift his / her posture, and it is possible to easily wash the hair.

Further, as shown in FIG. 3, not only the face packing 3 but also the foaming sealing material 3d mainly on the forehead part.
And the skirt 3c hit twice. Therefore, the nozzle 1b
Even in the case where the shower head 1c and the shower head 1c are concentrated on the hairline of the forehead, the strong seal prevents the wash water and shampoo from leaking out.

The face packing 3 is reinforced by pressing plates 4 to 7 on its upper and lower surfaces, and these pressing plates 4 to 7 strengthen the waist of the seal portion around the notch 3b and in close contact with the face. For this reason, the sealing force of the face packing 3 is also kept high, and leakage of cleaning water or the like can be reliably prevented.

When the face packing 3 is moved back and forth, the through holes 4 of the holding plates 4 to 7 are also used.
Since the a to 7c and the through hole 3a of the face packing 3 move integrally by the movement of the bolt 8b, the pressing plate 4 is pressed against the sealing surface at the edge of the face packing 3.
7 to 7 can always occupy an appropriate position and can maintain a good sealing pressure.

In the above example, the face packing 3 is made of one piece, but it may be divided into two pieces and arranged in postures such as the holding plates 4 and 5, and the fixing tool 8 is operated. The two face packings can be moved according to the position of the person's head.

FIG. 6 is a plan view of the cover 2 and face packing showing another example, and FIG. 7 is a vertical sectional view taken along the line BB of FIG.

The cover 2 is provided with three guide holes 2a,
The face packing 9 is constrained by a fixture 10 inserted through these guide holes 2a. Further, unlike the previous example, the face packing 9 is held only by its lower surface side by the two holding plates 11 and 12.

As shown in FIG. 7, the fixture 10 is a knob 10
a bolt 10b integrally provided with a, a pressing plate 11,
A retainer nut 10c, which is located on the lower surface side of 12 and is screwed into the bolt 10b, is provided, and a washer 10d made of synthetic resin is incorporated between the knob 10a and the cover 2. Then, screw 10 to retainer nut 10c.
The presser plates 11 and 12 are connected via e, and the fixture 1
By moving 0 in the guide hole 2a, the positions of the pressing plates 11 and 12 can be changed as in the previous example.

In such a structure of the fixture 10, the composite 1
Since the washer 10d made of 0c slides on the surface of the cover 2, the resistance when moving the fixture 10 can be reduced, and the position of the face packing 9 can be set quickly.

FIG. 8 is a vertical sectional view taken along the line CC of FIG. 6, and FIG. 9 is a cutaway plan view showing the left half of the face packing 9.

The face packing 9 has a U-shaped plane shape with the front end side opened like the previous example, and three through holes 9a for inserting the bolts 10b of the fixture 10 are opened and the face packing 9 is formed at the center. Shows that an inverted U-shaped notch 9b is formed. Around the notch 9b, a skirt 9c is provided which has a downwardly bent cross-sectional shape and is in close contact with the person's forehead. As shown in FIG. 8, the skirt 9c has a cross-sectional shape in which the lower end portion is slightly bent toward the person's head side.

On the lower surface of the face packing 9 and at a position along the skirt 9c with a little space left between them,
A guard 9d is provided. The guard 9d has a sectional shape slightly longer than the skirt 9c in a posture in which the guard 9d is bent substantially at right angles to the surface of the face packing 9. And guard 9
Since d is located on the head side of the skirt 9c that is in close contact with the person's forehead and on the upstream side where the shampoo and washing water are sprayed, the skirt is directly sprayed when these shampoo and washing water are sprayed. It serves to prevent hitting 9c.

FIG. 10 shows the details of the face packing 9, and FIG. 10A is a partial cutaway view showing only the face packing 9.

The face packing 9 is formed in a planar shape except for the skirt 9c portion, and the entire outer contour of the planar shaped portion is provided with a ridge 9e slightly protruding upward. As shown in FIG. 10B, the ridge 9e has a semicircular vertical cross-sectional shape, and is assembled so that the ridge 9e is in line contact with the lower surface of the cover 2 covering the face packing 9.

6 to 10, since the face packing 9 is in line contact with the lower surface of the cover 2 of the ridge 9e, when the fixture 10 is loosened and the face packing 9 is moved, the ridge 9e moves. Since only the 9e portion slides on the lower surface of the cover 2, the frictional resistance is reduced. Therefore, the position of the face packing 9 can be easily changed, and the handling becomes easier.

Further, when the face packing 9 is positioned and tightened by the fixture 10, the sealing pressure due to the line contact of the ridge 9e can be increased. For this reason, it is possible to obtain usability in which washing water, shampoo liquid, etc. do not leak when washing hair.

Further, when washing the hair, the skirt 9c of the face packing packing 9 is tightly attached around the person's forehead to prevent leakage of washing water or shampoo liquid. On the other hand, this skirt 9d
If you press the forehead around with too strong force, you will feel pain and it is not preferable from the viewpoint of usability. Therefore, in order to moderate the sealing pressure by the skirt 9c, such a problem can be solved by using the pressing surface 9c-1 in which the portion corresponding to the forehead is bent toward the head side.

Here, if the sealing pressure by the skirt 9c is not so strong, the possibility of water leakage cannot be ignored. On the other hand, in the present invention, since the guard 9d is provided in the portion located closer to the head side than the skirt 9c,
The guard 9d serves as a barrier against the jet flow from the nozzle 1b, the shower head 1c and the like shown in FIG. Therefore, even if the sealing pressure of the skirt 9c is not made strong, it is possible to prevent leakage of washing water and the like, and it is possible to eliminate the inconvenience such as bathing water on the face and shampoo liquid getting into the eyes. .

Further, when the lower end of the skirt 9c is positioned so as to hit the forehead, the guard 9d can be set at a position corresponding to the hairline of the hair. For this reason, the cleaning liquid or the spray liquid such as shampoo liquid easily hits the guard 9d and bounces back to the hair side, so that sufficient cleaning water or shampoo liquid can be poured onto the hair, and the hair-washing ability is also improved.

[0049]

According to the present invention, even if the position of the person's head facing the ball is not appropriate, the face packing can be moved back and forth to cover the forehead and the chin and seal. , It can be used by a person who lay on his back on a chair without moving his body. Also, when the head is in front of a predetermined position, if the face packing is moved forward, it will be deformed so that its width direction becomes narrower, so that the sealing of the jaw part is not particularly bad, Is surely prevented from leaking.

Further, since the upper and lower surfaces of the face packing are reinforced by the pressing plates, it is possible to strengthen the rigidity toward the sealing surface of the edge portion, so that the leakage of washing water can be prevented more reliably.

Further, by bending the lower end of the skirt to form a pressing surface, the tightening force applied to the forehead can be reduced. By providing a guard on the back side of the skirt, even if the seal by the skirt is loose, this water can be washed by the guard. It can block the spray of water and can be used without getting your face wet.
