Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device for washing a human body part after use, and more particularly to a sanitary washing device capable of changing a washing range without moving a washing nozzle. is there.

[0002]

2. Description of the Related Art As a cleaning device of this type for cleaning a human body, there is a cleaning nozzle having a single or a plurality of nozzles for spraying warm water to intensively clean a local part. Although a feeling can be obtained, it was not possible to perform a wide range of cleaning adapted to the human body part. Further, there is a problem that the cleaning efficiency cannot be improved because the cleaning water does not change in the portion to be cleaned. That is, the cleaning of the filth adhering to the part to be cleaned, the fluid enters the joint between the surface to be cleaned and the filth,
There is a process of lowering this binding force and a process of colliding the cleaning fluid with the portion to be cleaned to peel off the dirt. To enhance the peeling effect, it is effective to move the jet in the portion to be cleaned. Is.

Therefore, in recent years, as shown in FIG. 6, the entire cleaning nozzle is reciprocated by a driving means such as a motor.
It has been proposed to change the cleaning jet to realize a wide range of cleaning suitable for a human body part and to improve the cleaning efficiency (Japanese Utility Model Laid-Open No. 63-56775). In the figure, reference numeral 1 is a cleaning nozzle, in which cleaning water supplied from a cleaning water supply means (not shown) flows in through a water supply port 2 and is ejected toward a human body part from an ejection hole 3 provided at a tip portion. To do. Reference numeral 4 denotes a motor for driving the cleaning nozzle 1 forward and backward, the driving force of which is a speed reduction means 5 composed of gears 5a, 5b, 5c, 5d, a wire 7 wound around a shaft 6 of the gear 5d, and a rotor. Linear motion conversion means 9 composed of 8
And the cleaning nozzle 1 connected to the wire 7 by the connecting portion 10 can be moved forward and backward.
Reference numeral 11 is a photo interrupter that detects the amount of advance of the cleaning nozzle 1, and the advance position of the cleaning nozzle 1 is detected by counting the number of slits (not shown) formed in the side surface of the gear 5d.

When the cleaning start switch (not shown) is turned on in the above structure, the motor 4 is activated and the speed reducing means 5 is activated.
The cleaning nozzle 1 is driven to move from the retracted position in the cleaning nozzle 12 to the human body local position shown in FIG. 6 through the linear motion converting means 9, and the cleaning water flowing from the water supply port 2 is discharged from the ejection hole 3. . On the other hand, the advancing amount of the cleaning nozzle 1 is detected by the photo interrupter 11. The motor 4 is stopped at the advancing position, and the cleaning nozzle 1 is driven back and forth at predetermined intervals as necessary to perform a wide range of cleaning suitable for the human body part. At the same time, high cleaning efficiency is realized.

[0005]

However, in the conventional cleaning device as described above, since the entire cleaning nozzle is moved, the motor as the driving means, the speed reducing means, and the rotational movement of the motor are changed to the forward / backward movement of the cleaning nozzle. The linear motion converting means, the position detecting means for detecting the advancing state, and the like are required, and there is a problem that the apparatus becomes complicated, the size becomes large, and the price becomes high accordingly.

The present invention is intended to solve the above problems,
The cleaning water ejected from the two kinds of ejection holes can be merged, and the flow rate of the cleaning water ejected from each ejection hole is adjusted so that a wide range of human body parts suitable for the human body part can be obtained without moving the entire cleaning nozzle. It is an object of the present invention to provide a sanitary washing device that can perform washing and can improve washing efficiency and that has a simple structure.

[0007]

In order to achieve the above object, a sanitary washing device of the present invention has a washing water supply means, a water supply passage, and a washing nozzle for jetting the washing water toward a human body part. The cleaning nozzle has first and second flow paths and first and second ejection holes communicating with the respective flow paths, and joins the cleaning water from the first and second ejection holes. The first flow path and the first flow path upstream of the first and second flow paths.
And a flow ratio control means for controlling the distribution ratio of the amount of wash water supplied to the second flow path.

[0008]

In the sanitary washing device of the present invention, the washing water from the first and second jet holes can be combined with each other, and the amount of washing water in the first jet hole and the second jet hole are controlled by the flow ratio control means. Since the ratio of the amount of cleaning water from the control unit is controlled, the behavior of the combined cleaning jets changes depending on the flow rate ratio to the two flow paths, and the cleaning position or cleaning range on the surface to be cleaned can be adjusted. As a result, the cleaning range can be adjusted without moving the entire nozzle device, and the cleaning efficiency can be improved by changing the behavior of the cleaning jet. Further, since it is not necessary to move the entire cleaning nozzle, the structure can be simplified.

In addition, first and second jet holes are provided so that the jet streams can be brought into contact with each other, and the first and second jet holes are provided corresponding to the respective jet holes.
And a second flow path is provided, and a flow ratio control valve for controlling the ratio of the flow rates supplied to these flow paths is provided, and the behavior of the combined cleaning jet changes depending on the flow rate ratio to the two flow paths. Therefore, the cleaning position or cleaning range on the surface to be cleaned can be adjusted.

Further, since the flow ratio control means is provided on the upstream side of the first and second flow paths, not only the flow ratio control of the first and second flow paths but also the first flow path or the second flow path is performed. Since the cleaning water can be supplied only to the flow path, it becomes possible to discharge the cleaning water by the first ejection hole and the second ejection hole independently.

Position, ie first and second flow paths 25, 26
The cleaning operation is completed by setting the flow rate ratio to be distributed to the same. Therefore, when the next user turns on the cleaning switch 43 again, the cleaning is started based on a predetermined initial setting condition.

In the above structure, the operation of this embodiment will be described below.
The operation will be described. When the cleaning switch 43 is turned on, the cleaning water supply means 13 operates according to the condition set by the initial setting means 52, and the cleaning water flows into the flow rate control valve 29 through the warm water tank 16. Here, the valve plug 34 of the flow ratio control valve 29 is set to the position of the rotation angle 0 as shown in FIG. 4, and the first and second water outlet ports 32a,
It is distributed from 32b to the first and second water supply ports 20a and 20b at the same rate with respect to the supply amount, that is, every 50%. When the wash water flows into the nozzle cylinder 21, water pressure acts on the movable water supply body 23 to move it forward to move the nozzle element 2
When 2 reaches the human body local position, the water stops and the washing water is ejected from the first and second ejection holes 28a and 28b.

Since the jet holes 28a and 28b are inclined with an angle of θn, the jetted wash water joins at the point P and becomes a concentrated jet stream as shown by the solid line in FIG. As a result, it collides with the substantially central portion of the portion to be cleaned A and cleaning is performed.
By operating the water pressure adjustment switch 46, the water pressure according to the user's preference can be selected. The cleaning position at this time may not be optimum depending on individual differences and seating positions. In such a case, for example, when it is desired to move the cleaning jet forward with respect to the user, if the forward switch 50a of the position adjusting switch 49 is turned on once, the flow rate ratio adjusting means 51 outputs the flow rate ratio adjusting means. 45 operates, and as shown in FIG. 5, the valve plug 34 of the flow ratio control valve 29 is driven to rotate by a predetermined angle θb1 in the direction of θb from the position of rotational angle 0 and is supplied to the first flow path 25. As the flow rate Q1 decreases, the flow rate Q2 supplied to the second flow path 26 increases. As a result, as shown in FIG. 2, the jetting force from the second jetting hole 28b is strengthened, and the washing position by the jet stream moves in the direction of arrow F (front with respect to the user). If you want to move further forward, press the forward switch 5 again.
This can be done by operating 0a to set the rotation angle to θb2, and when reversing is desired, select the retreat switch 50b so that the cleaning position is stepwise in the front-rear direction with the approximate center of the portion to be cleaned A as a reference. Can be adjusted.

Next, the operation of the flow rate ratio continuously varying means 48 will be described. When the rocking selection switch 47 is turned on after the cleaning switch 43 is turned on, the flow rate ratio continuously changing means 4
8 operates to output a signal to the flow rate ratio varying means 45, and the valve plug 34 of the flow rate control valve 29 is continuously and alternately reversed in the range from θa to θb shown in FIG. The ratio of the flow rates Q1 and Q2 supplied to the second flow paths 25 and 26 is continuously increased and decreased. As a result, the first and second ejection holes 28a, 28
The cleaning water ejected from b is increased and decreased alternately and continuously. As shown in FIG. 2, if Q1 increases, the cleaning position is in the direction of arrow B, and if Q2 increases, the cleaning position is indicated by arrow F. Direction, and these are alternately repeated in the front-rear direction with the substantially center of the portion to be cleaned A as a reference, thereby making it possible to clean a wide range by swinging the jet flow. The swing width Wn of the jet flow is proportional to the inclination angle θn of the jet holes 28a and 28b,
If the inclination angle θn is set large, the swing width Wn or the position adjustment width can be set large. The swing cycle in the swing cleaning depends on the operation speed of the flow rate control valve 29, that is, the rotation speed of the stepping motor 39 and the speed reduction ratio of the speed reduction means 40.

As described above, in this embodiment, the portion to be cleaned A is
The first and second ejection holes 28a, 28b capable of contact merging with the jets are provided by inclining the axes at a predetermined angle θn so that the axes intersect at a point P located substantially on the central axis of each of the ejection holes 28a. , 28b, two flow paths 25, 26 are provided, and a flow rate ratio control valve 29 for controlling the ratio of the flow rates supplied to the flow paths 25, 26 is provided. By controlling the flow rate ratios to be the same, a concentrated cleaning jet can be obtained, and by selecting the swing selection switch 47, the flow rate ratio changes continuously, without moving the entire cleaning nozzle 19. An oscillating jet that can perform a wide range of cleaning can be selected. Therefore, the optimum cleaning jet can be easily selected according to the physical condition, age, preference, etc. of the user, and the structure of the cleaning device can be simplified and the cost can be reduced. Furthermore the first
And the flow ratio control valve 2 on the upstream side of the second flow paths 25 and 26.
Since 9 is provided, not only the flow ratio control of the first and second flow paths 25 and 26 but also only the first flow path 25 or the second flow path 25 is performed.
Since it is possible to selectively supply the cleaning water only to the flow path 26 of the first ejection hole 28a and the second ejection hole 28b, it is possible to discharge the cleaning water independently. Different cleaning jets can be ejected by changing the specifications of the holes 28a and 28b, for example, different hole diameters.

Further, as the flow rate ratio control valve 29, a method in which the valve plug 34 is rotationally driven by the stepping motor 39 to adjust the flow rate ratio is used. Therefore, the flow rate ratio is controlled with high accuracy by controlling the pulse signal supplied to the stepping motor 39. Therefore, the feedback control by detecting the rotation angle is unnecessary. Therefore, a rotation angle detecting means and a control circuit therefor are not required, and the cost can be reduced.
Further, since the seal member 37 made of a polymer material containing tetrafluoroethylene is integrally formed on the surface of the valve plug 34, the friction coefficient at the time of rotation can be reduced and the torque of the stepping motor 39 can be reduced. In addition, the reliability of the control fluid against external leakage is improved.

By operating the position adjusting switch 49,
The cleaning position can be adjusted by adjusting the flow rate ratio stepwise. As a result, a cleaning position suitable for the user can be selected without moving the entire cleaning nozzle 19, and a driving device such as a motor, a deceleration means, a linear motion conversion means, etc., which is required in the conventional example, is unnecessary, and the apparatus becomes complicated or complicated. The cleaning position can be adjusted without increasing the price.

Further, since the initial setting means 52 is provided, the use condition of the previous user is canceled, and when the use is started, the cleaning is always started at the preset water force and the cleaning position, which is unnecessary for the user. Switch operation is reduced. This is suitable for this type of sanitary washing device with multiple users.

[0027]

As described above in detail, the sanitary washing device of the present invention can adjust the washing range without moving the entire nozzle device and can improve the washing efficiency by changing the behavior of the washing jet. Become. Further, since it is not necessary to move the entire cleaning nozzle, a drive unit such as a motor, a speed reducer, a linear motion converter, etc., which is required in the conventional example, is unnecessary, and the configuration can be simplified and the cost can be reduced.
