[Detailed Description of the Invention] The present invention relates to a human body private parts cleaning device used in a toilet.

Generally, this type of device has a structure that allows for cleaning the anus after defecation (hereinafter referred to as "shower cleaning") and cleaning the genitals of women (hereinafter referred to as "bidet cleaning").

In conventional devices of this type, a nozzle is provided at the front end of a nozzle that is extendable to the toilet wall, but the jetting area of the nozzle is fixed. It is not possible to select the ejection area according to the user's preference, so it is difficult to obtain a good feeling based on the optimal water force especially when washing the bidet, and the washing area is limited and the washing effect is not good. It was hot.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the conventional apparatus, an object of the present invention is to provide a human body private part cleaning device in which the ejection area of the ejection hole at the front end of the nozzle is variable. Further, the present invention aims to improve the feeling particularly during bidet cleaning by changing the cleaning area by using the variable ejection area type. In addition, the present invention aims to provide a human body private parts cleaning device that is easy to maintain and manage by having a double nozzle, with the outer nozzle being shorter than the inner nozzle, and by configuring the outer nozzle to be detachable. .

The present invention cleans private parts of the human body, which has a toilet bowl wall and a nozzle that is telescopically held on the toilet wall via a fixing member and that jets cleansing water from a jet hole at the front end through a passage formed inside. In the human body private part cleaning device, the nozzle is arranged such that the nozzle is arranged in the fixing member so as to be extendable and rotatable; an outer nozzle having a shorter length than the inner nozzle; a second ejection hole formed in the outer nozzle and capable of aligning with either one of the first ejection holes, and a nozzle expansion/contraction means for integrally expanding and contracting both the nozzles; a first motor formed on the fixed member;
and a second engaging portion that is formed on the outer nozzle and engages with the first engaging portion at a rearmost position of the outer nozzle to make the outer nozzle unrotatable. .

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Figure 1 is a side view showing an embodiment of the present invention;
The figure is a sectional view taken along the - line in FIG. 1, and the reference numeral 2 in the figure is a fixed frame, including rubber intervening members 3, 4, washers 5, and a nozzle guide (fixing member).
It is fixed to the toilet bowl wall W via a nut 7 through a screw 6. A motor M ₁ (which can rotate in forward and reverse directions) is fixed to the lower surface of the fixed frame 2, and its rotational force is transmitted to other pulleys 10 and 11 via a pulley 8 and a wire (or a wrapping member such as a rope) 9. . Both pulleys 1
0 and 11 are the stays 1 on the lower surface of the fixed frame 2.
It is rotatably mounted via 0A and 11A. The wire 9 connects three pulleys 8, 10, 11
and both ends thereof are attached to the lower end of the movable body 12. For this, for example motor M ₁
When the pulley 8 fixed to the shaft rotates counterclockwise in FIG.
Motor M ₂ both move in the direction of arrow a (hereinafter, this direction is
(referred to as "forward" and the direction a' is referred to as "backward"). During this movement, the movable body 12 is guided by two guide rods 14 and 15 (see FIG. 4) whose both ends are fixed to the fixed frame 2 to ensure smooth movement. ing.

The rear end of the inner nozzle 13 is rotatably fitted into the hole of the movable body 12, and the rotating shaft 16 of the motor _M2 is fitted into the end face of the rear end so that it can rotate integrally with the inner nozzle 13. There is.

A passage 13a is formed in the center of the inner nozzle 13 in the axial direction, and the rear end of the passage 13a has a passage 13b formed in the radial upward direction and an annular groove 1 on the outer periphery.
3c, it communicates with a passage inside the external water guide pipe attachment member 17.

A plug 18 is driven and fixed at the front end of the inner nozzle 13, and three small holes 1 are formed at three equal parts (although not necessarily at equal parts) on the outer circumference of the front end.
The first ejection hole 131 consists of four small holes 142 and the first ejection hole 132 consists of four small holes 142.
The first ejection hole 133 is composed of small holes 143.
are formed respectively (see Figure 3). On the other hand, between the nozzle guide 6 and the inner nozzle 13, an outer nozzle 19 made of resin is attached to the inner nozzle 13 with a retaining ring (connecting member) 20. The outer nozzle 19 has an extremely small length in the axial direction (front-back direction) than the inner nozzle 13, and has a convex portion (second engaging portion) 19a (see FIG. 1) with a rectangular cross section at one location on its outer periphery. The inner nozzle 1 can be rotated around the axis by the rotation of the motor _M2 . , the outer nozzle 19 cannot rotate. However, the outer nozzle 1
9 is movable integrally with the inner nozzle 12 when it starts to move forward from the rearmost position as shown in FIG.
When the convex portion 19a and the groove 6a are disengaged by movement of the nozzle 9, both the nozzles 13 and 19 can rotate integrally around the axis.

As shown in FIG. 4 or 5, the outer nozzle 19 has
Second ejection hole 19 composed of five small holes 181
1 is formed, and the first ejection holes 131, 132, 133 formed in the inner nozzle 13 and FIG.
They can be selectively matched as shown in FIGS. 5a and 5b. In this case, the second ejection hole 19
The cross-sectional area of each small hole 181 is equal to that of the first ejection hole 131,
The cross-sectional areas of the small holes 141, 142, 143 of the holes 132, 133 are larger than those of the small holes 141, 142, 143. In addition, the second ejection hole 191 of the outer nozzle 19 and the inner nozzle 1
3, the inner nozzle 13 is rotated by the motor _M2 while the outer nozzle 19 is accommodated in the nozzle guide 6 as shown in FIG. This is done by causing Since the motor M ₂ is a pulse motor, by controlling the rotation speed or rotation angle of the motor M ₂ , the second ejection hole 191 and the first ejection holes 131, 132, 133 can be selectively aligned as described above. can be done. (This matching may be automated or manual). When they match in this way, and when water in a certain number of holes is introduced into the inner nozzle 13, the first ejection holes 131, 1
Cleaning water is ejected upward from either of the holes 32, 133 (small holes 141, 142, 143) through the second ejection hole 191 (small hole 181).

Although the small hole 181 has a circular cross section, it is not limited to such a shape;
Any shape is sufficient as long as it has a larger cross-sectional area than the cross-sectional areas of 41, 142, and 143 and allows cleaning water to be jetted out without resistance.

Since the outer nozzle 19 is only fixed to the front outer circumference of the inner nozzle 13 by the retaining ring 20, if the outer nozzle 19 is pulled forward with the protrusion 19a removed from the groove 6a, It can be easily removed from the inner nozzle 13. Therefore, it is easy to clean the outer nozzle 19, which is advantageous in terms of maintenance.

FIG. 4 is a plan view of FIGS. 1 and 2, and also illustrates means for guiding the cleaning water to the passage 13a in the inner nozzle 13, and also shows that the movable body 12 is moved forward to some extent. This shows the state in which the In this figure, reference numeral 21 denotes a water guide pipe, one end of which is connected to the water guide pipe attachment member 17 and the other end connected to the upper part of the hot water tank 22. A heater 23 is installed in the hot water tank 22 to heat the water in the hot water tank 22.
A water supply tank 24 is located below the hot water tank 22.
Water is supplied via an electromagnetic valve 25 and a pump 26. The electromagnetic valve 25 is provided to close the nozzles 13 and 19 so that the cleaning water does not fall and leak from the tips of the nozzles 13 and 19 when the apparatus is not in use.

Next, we will discuss the effect. In the state shown in FIG. 2 (the state in which the inner nozzle 13 and the outer nozzle 19 are located at the rearmost position, that is, the state in which the protrusion 19a and the groove 6a are engaged and the outer nozzle 19 cannot rotate), the attached switch is (not shown) presses the motor.
_M2 starts, the inner nozzle 13 rotates around its axis, and one of the first ejection holes 131, 132, and 133 coincides with the second ejection hole 191. In other words, the user can freely and automatically select the first jetting holes 131, 132, 133, thereby adjusting the jetting amount and cleaning area of the cleaning water.

After making the above adjustments, after the toilet user finishes defecating, use the attached shower cleaning station (not shown).
When is pressed, the motor _M1 rotates, and the movement of the wire 9 causes the movable body 12 to move forward (in the direction a) by a "certain distance" from the rearmost position shown in the second figure, and both nozzles 13 and 19 perform "shower cleaning". position”. still,
The "certain distance" is determined by determining the seating position of the user. Further, since the motor _M1 is a pulse motor, it can be automatically stopped after a certain rotation, and therefore the movable body 12 can be stopped after traveling the "fixed distance". Further, the "fixed distance" can be changed and set as appropriate by controlling the motor rotation speed.

In this state, the pump 26 starts to operate simultaneously with the OFF operation of the motor M ₁ , and the electromagnetic valve 25 also opens at the same time, so that hot water is force-fed to the passage 13 a in the inner nozzle 13 . Nozzle holes 131, 132, 133, (small hole 14
1, 142, 143) from the outer nozzle 1
Hot water is vigorously jetted out through the second jetting holes 191 (small holes 181) of No. 9 to perform shower cleaning.

Thereafter, the motor _M1 rotates in the reverse direction due to the action of the timer, so that both nozzles 13 and 19 return to the rearmost position in FIG. At this time, the rotation speed of the motor _M2 is controlled so that the convex portion 19a of the outer nozzle 19 and the groove 6a engage with each other.

After making the above adjustments, after the toilet user finishes defecating, turn on the attached bidet cleaning switch (not shown).
When pressed, the motor _M1 rotates, and the wire 9 moves to move the movable body 12 a certain distance from the rearmost position shown in the second figure (further forward than the above-mentioned "shower cleaning position", specifically, the "shower cleaning position"). ” than 4
Move forward (direction a) by about cm),
Both nozzles 13 and 19 are in the "bidet cleaning position".
After that, it operates in the same way as shower cleaning, and bidet cleaning is performed.

During the above-mentioned shower cleaning and bidet cleaning (protrusion 1
9a and groove 6a), the pulse motor
By controlling the rotation speed of M ₂ and slightly rotating (swinging) the inner nozzle 13 and outer nozzle 19 around their axes, the cleaning area can be increased, and the cleaning effect especially when cleaning the bidet can be improved. This can contribute to improved soft cleaning and feeling.

Although the motors M ₁ and M ₂ are pulse motors in this embodiment, they may be ordinary motors as long as the number of revolutions can be controlled. Further, the means for expanding and contracting both nozzles 13 and 19 is not limited to the motor M ₁ , the wire 9, and the pulleys 8, 10, and 11. Moreover, both nozzles 13 and 19 do not necessarily have to be configured to be slightly rotated around the axis. Furthermore, by forming a through hole in the part of the nozzle guide 6 where the front ends of both nozzles 13 and 19 are housed, and connecting it to the water supply tank 24 using a communication pipe, the water in the water supply tank can be used to connect both nozzles 1 to the nozzle 1.
It may also be configured to wash away dirt that may adhere to the front ends of the parts 3 and 19, thereby removing foul odors and the like generated from the dirt.

As described above, the present invention includes a toilet bowl wall and a nozzle that is telescopically held on the toilet bowl wall via a fixing member and that spouts cleansing water from the jet hole at the front end through a passage formed inside. In a human body private part cleaning device for cleaning a human body private part, the nozzle is arranged such that it can be contracted and rotated integrally with an inner nozzle that is extendably and rotatably disposed on the fixed member, and a front end of the inner nozzle. an outer nozzle having a shorter length than the inner nozzle, and the ejection hole is formed of a plurality of small holes each formed at the front end of the inner nozzle, each having a different ejection area. a nozzle expanding/contracting means for integrally expanding and contracting both the nozzles, the second jetting hole being formed in the outer nozzle and capable of matching with any one of the first jetting holes; a motor that rotates the nozzle around its axis, a first engaging portion formed on the fixed member, and a motor that is formed on the outer nozzle and engages with the first engaging portion at a rearmost position of the outer nozzle. and a second engaging part that makes the outer nozzle non-rotatable, so that the inner nozzle is moved by the motor when the first engaging part and the second engaging part are engaged. By rotating, the first ejection hole can be selectively aligned with the second ejection hole, and the ejection area can be changed manually or automatically according to the user's preference. Therefore, the cleaning area can be changed, the cleaning efficiency can be improved, and the usability especially when cleaning the bidet can be improved. Furthermore, if the outer nozzle is detachably attached to the inner nozzle via a connecting member, the outer nozzle can be easily cleaned, which is advantageous in terms of maintenance.
