Description

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 is configured to perform anal cleaning after defecation (hereinafter referred to as "shower cleaning") and female genital cleaning (hereinafter referred to as "bidet cleaning").

In conventional cleaning devices of this kind, a nozzle for spouting hot water for cleaning is installed at the end of the toilet bowl wall so that it can expand and contract in a direction perpendicular to the wall, and the expansion and contraction action uses water pressure. I was doing it.

However, such devices that utilize water pressure have the disadvantage that the expansion and contraction speed of the nozzle changes when some unexpected change in water pressure occurs, and the nozzle does not extend to the set position when the water pressure falls below a certain level. Furthermore, although the users range from children to adults and their seating positions vary, the shower cleaning position and bidet cleaning position are always constant based on the amount of nozzle extension, making it impossible to make minute positional adjustments. Therefore, there was a drawback in that the user had to make small changes in the seating position.

In view of the above conventional drawbacks, the present invention moves a wrapping member such as a wire through a pulley using an electric means such as a motor, and causes a movable body connected to the member to reciprocate in the front and back direction. By configuring the nozzle to reciprocate together with the movable body,
It is an object of the present invention to provide a human body private parts cleaning device which ensures the reliability of the reciprocating movement of the nozzle and also allows fine adjustment of the shower cleaning position and the bidet cleaning position.

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

FIG. 1 is a side view showing an embodiment of the present invention, and FIG.
The figure is a cross-sectional view taken along the - line in FIG. 1, and the reference numeral 2 in the figure is a fixed frame. Fixed. A first pulse motor M ₁ (which can rotate in forward and reverse directions) is fixed to the lower surface of the fixed frame 2, and applies rotational force to other pulleys 10 and 11 via a pulley 8 and a wire (or a wrapping member such as a rope) 9. can be conveyed. 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 its both ends are attached to the lower end of the movable body 12. For this reason, for example, the first motor
When the pulley 8 fixed to the shaft of _M1 rotates counterclockwise in FIG. 2, the wire 9 is pulled in the direction of the arrow, so that the movable body 12
3. The second motor _M2 moves both in the direction of the arrow a (hereinafter, this direction will be referred to as "forward" and the direction a' will be referred to as "rear"). During this movement, two guide rods 14 and 15 are fixed at both ends to the fixed frame 2 to ensure smooth movement.
The movable body 12 is guided by (see FIG. 4).

The rear end of the nozzle 13 is rotatably fitted into the hole of the movable body 12, and the rotating shaft 16 of the second motor _M2 is fitted into the end face of the rear end so as to be able to rotate together with the nozzle 13. There is.

A fluid passage 13a is axially bored in the center of the inner nozzle 13, and the rear end of the passage 13a is connected to an external water guide pipe through a passage 13b bored radially upward and an annular groove 13c on the outer periphery. It communicates with a passage within the mounting member 17 .

A plug 18 is driven into and fixed to the front end of the inner nozzle 13, and three small holes 131, 4 are formed at three equal parts (although not necessarily at equal parts) on the outer circumference of the front end. 1 small hole 132, 5 small holes 1
33 are bored in each case (see Fig. 3).
On the other hand, an outer nozzle 19 made of resin is disposed between the nozzle guide 6 and the inner nozzle 13, and a retaining ring 2
0 to the inner nozzle 13. 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 19a (see FIG. 1) with a rectangular cross section formed at one location on its outer periphery. Groove 6 of the same shape
It is fitted in a. Therefore, the inner nozzle 13 can be rotated around the axis by the rotation of the second motor _M2 , whereas the outer nozzle 19 cannot be rotated. However, the outer nozzle 19 can be moved together with the inner nozzle 13 when it starts to move forward from the rearmost position as shown in FIG. Twisted convex portion 1
When the engagement between the groove 9a and the groove 6a is removed, both nozzles 13,
19 can integrally rotate around the axis.

5 as shown in FIG. 4 or 5 on the outer nozzle 19.
5 holes 133, 4 holes 132, and 3 holes 131 formed in the inner nozzle 13 as shown in FIGS. They can be matched. In this case, each cross-sectional area of the hole 191 of the outer nozzle 19 is formed to be larger than that of the holes 133, 132, 131 of the inner nozzle. The alignment of the holes is achieved by rotating the inner nozzle 13 with the second motor M2 while the outer nozzle ₁₉ is accommodated in the nozzle guide 6 as shown in FIG. Since the second motor _M2 is a pulse motor,
By controlling the rotation speed or rotation angle of the second motor _M2 , both nozzles 13, 19 are controlled as described above.
holes can be selectively matched. (This matching may be automated or manual). When they match in this way and when water at a constant pressure is introduced into the inner nozzle 13, cleaning water is ejected upward from any one of the holes 131, 132, and 133.

Although the hole 191 of the outer nozzle 19 has a circular cross-section, it is not limited to such a shape, and the cross-sectional area of the hole 191 of the outer nozzle 19 is larger than that of the holes 131, 132, and 133 so that the cleaning water can be jetted out without resistance. Any shape is fine.

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. It is in a state of being In this figure, reference numeral 21 denotes a water guide pipe, one end of which is connected to the mounting member 17 and the other end connected to the upper part of the hot water tank 22. A heater 23 is installed in the tank 22 to heat the water in the tank 22. At the lower part of the tank 22, water from the water supply tank 24 is supplied to a solenoid valve 2.
5. Supplied via pump 26. The electromagnetic valve 25 allows cleaning water to flow through the nozzle 1 when the device is not in use.
3 and 19 to prevent leakage from falling from the tips.

Next, we will discuss the effect. When a toilet user finishes defecating and wants to shower, use the inner nozzle 13.
Before operating the outer nozzle 9 to advance to the shower cleaning position, the following adjustment operation is performed in advance. First, the outer nozzle 9 is connected to the nozzle guide 6.
When the switch is in the rearmost position, press the attached switch (not shown). Then the second motor
_M2 starts and the inner nozzle 13 rotates around the axis relative to the outer nozzle 9, and the three holes 131 and the four holes 1
32 or 5 holes 133 corresponds to the hole 191 of the outer nozzle 9. In other words, the user
31, 132, and 133 can be freely and automatically selected, thereby making it possible to adjust the jetting amount and jetting area (washing area) of the cleaning water when the inner nozzle 13 and the outer nozzle 9 advance to the shower cleaning position. can.

Then, when the attached shower cleaning switch (not shown) is pressed, the first motor _M1 rotates and the wire 9
As a result of this movement, the movable body 12 moves forward (in the direction a) by a "certain distance" from the rearmost position shown in the second figure, and the inner and outer nozzles 13 and 19 are placed in the "shower cleaning position". The "certain distance" is determined by determining the seating position of the user. In this embodiment, the first motor _M1 is a pulse motor, and can be automatically stopped after a certain rotation, so that the movable body 12 can be stopped after traveling the certain distance. Further, the constant distance can be changed and set as appropriate by controlling the motor rotation speed.

Simultaneously with the OFF operation of the first motor _M1 , the pump 26 starts operating, and at the same time, the electromagnetic valve 25 is also opened, and hot water is supplied to the passage 1 in the inner nozzle 13.
3a. Therefore, hot water is vigorously jetted out from the hole 191 of the outer nozzle 19 with which any of the holes 131, 132, 133 of the inner nozzle 13 coincides. This allows shower cleaning.

Then, when the shower cleaning is finished, the first motor _M1 rotates in the reverse direction due to the action of the timer, and the nozzle 13,
19 returns to the rearmost position in FIG. At this time, the rotation speed of the second motor _M2 is controlled so that the convex portion 19a of the outer nozzle 19 and the groove 6a engage with each other. Incidentally, when the first motor _M1 starts rotating in reverse, the operation of the pump 26 is stopped, and at the same time, the electromagnetic valve 25 is closed.
is also in a closed state, and the pressure feeding of hot water to the passage 13a in the inner nozzle 13 is stopped.

When performing bidet cleaning, the following adjustment operation is performed in advance when the user advances the inner nozzle 13 and outer nozzle 9 to the bidet cleaning position, as in the case of shower cleaning. first,
With the outer nozzle 9 housed in the nozzle guide 6 and located at the rearmost position, an attached switch (not shown) is pressed. Then, the motor M ₂ starts, and the inner nozzle 13 rotates around the axis relative to the outer nozzle 9, so that one of the three holes 131, four holes 132, and five holes 133 matches the hole 191 of the outer nozzle 9. do. This makes it possible to adjust the jetting amount and jetting area (washing area) of the cleaning water when the inner nozzle 13 and the outer nozzle 9 advance to the bidet cleaning position.

Thereafter, by pressing the attached bidet cleaning switch (not shown), the first 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 diagram (from the shower cleaning position mentioned above). The nozzles 13 and 19 move further forward (more specifically, about 4 cm), and both nozzles 13 and 19 are in the bidet cleaning position. Then, the pump 26 is activated in the same way as in shower cleaning, the solenoid valve 25 is opened, and hot water is supplied to the inner nozzle 1.
3 into the passage 13a. For this reason, as described above, the holes 131, 132, 1 are appropriately selected.
Bidet cleaning can be performed by adjusting the amount of cleaning water and cleaning area that are adjusted to suit the user's preference.

Then, when the bidet cleaning is finished, the first motor _M1 rotates in the reverse direction due to the action of the timer. As a result, both nozzles 13 and 19 operate as they did when the shower cleaning was completed.
Upon returning to the rearmost position in FIG. 2, the pressure feeding of hot water to the passage 13a in the inner nozzle 13 is stopped.

In the above embodiment, the first motor M ₁ and the second motor M ₂ are pulse motors, but they may be ordinary motors as long as the number of rotations can be controlled.

Further, by controlling the rotation speed of the second motor _M2 , the inner nozzle 13 can be slightly rotated (swung) around its axis while the engagement of the convex portion 19a of the outer nozzle 19 is released. In such a case, the cleaning area will be large, and the cleaning effect will be particularly improved during bidet cleaning, contributing to soft cleaning and improved feeling.

As described above, the present invention provides a human body private parts cleaning device that cleans human body private parts by jetting cleansing water from a jet hole at the front end, in which a nozzle is provided so as to be extendable and retractable with respect to the toilet bowl wall. a fixed frame disposed on the wall and fixed to the wall; a threaded rod rotated by a motor fixed to the fixed frame; a movable body that is movable in the axial direction of the rod; a nozzle that is movable in the axial direction together with the movable body and that allows cleaning water to be guided into an internal passage and spouted from a spout hole at the front end; Since the present invention is characterized by comprising a cleaning water supply means for supplying cleaning water to the passage, in order to achieve the present invention at a minimum, the number of both nozzles 13 and 19 in the above embodiment must be one. It is sufficient if one spout hole is drilled at the tip. Further, it is not necessarily necessary that the second motor _M2 rotates the inner nozzle 13 around its axis or slightly rotates it.

Since the present invention has the above-described structure and operation, the expansion and contraction speed of the nozzle is always constant, and the expansion and contraction length is not affected by changes in water pressure. In addition, by controlling the rotation speed of the motor that reciprocates the nozzle in the front-back direction, the shower cleaning position and bidet cleaning position can be finely adjusted, which eliminates the need for the user to adjust the seating position himself. do not have.
