Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sanitary cleaning device for a toilet seat or the like.

In general, this type of sanitary cleaning device is extremely clean and hygienic because it can easily wash the area to be cleaned by spraying hot water onto the area of the user after using the toilet. Therefore, it has become increasingly popular in recent years.

Figure 1 shows a conventional sanitary cleaning device.
1 is a toilet main body, 2 is a toilet seat rotatably installed on the top of the toilet main body 1, 3 is a toilet lid, and 4 is a flushing water pressure pump, a hot water tank, and various control devices (none of which are shown). This main case 4 is further equipped with a hot air blowing device 5 for drying.
At the same time, a hot air outlet 7 is provided at the tip of the air passage 6. 8 is the main body case 3
The washing water injection nozzle 8 is attached to the toilet bowl body 1 and faces into the toilet body 1. 9 is a low tank. When using this sanitary washing device, after using the toilet, first operate the washing water injection means, and hot water is sprayed from the washing water injection nozzle 8 onto the user's part to be cleaned. Wash off any dirt that has adhered to it. Next, when the hot air blowing means is operated, warm air is blown out from the hot air blowing port 7 to dry the attached moisture after cleaning.

However, in the above-mentioned conventional configuration, since the jetting direction of the cleaning water is constant, the position where the jetting cleaning water reaches may not match the part to be cleaned of the user 10 . In this case, the user 10
By appropriately adjusting the seating position of the cleaner, the jet of cleaning water is made to hit the spot where the dirt has adhered. In addition, if you not only wash away the adhering dirt with washing water, but also wash the surrounding area with washing water, you can enjoy a complete sense of cleanliness, but in order to maintain high cleaning power, concentrated washing is required. It is preferable to use water, and it is not preferable to simply diffuse the wash water. Therefore, the user 10 often moves his or her seated position by lifting his or her hips. However, if the dirt has spread when the user has diarrhea or a sick person uses the product, one feels the need to clean the surrounding area, but it is very painful to have to sit back while one's physical strength is low. It was something like that.

FIG. 2 shows another conventional example. That is, in this conventional example, a crank-shaped cleansing water injection nozzle 11 is arranged such that the center of its rotation axis is located between the toilet main body 1 and the toilet seat 2. By manually operating an operating lever (not shown) provided on the side of the toilet seat 2, the cleaning water injection nozzle 11 can be turned to the state shown by the solid line or the state shown by the dotted line. The cleaning water spray angle can be adjusted by moving. However, in this conventional example, when the spraying angle of the washing water is changed, the position where the sprayed washing water arrives moves slightly as a result, so although it is possible to select the spot where the washing water hits in the front and back direction, it is possible to do so. ,
Generally, the user 10 will adjust the seating position. In addition, in this conventional example, after washing off the dirt, it is possible to expand the washing position in the front and back directions by swinging a control lever (not shown), but this is limited to a small range, and the manual It has the trouble of repeating operations,
It was unreasonable for elderly people and children to continue operating the machine.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a sanitary washing device that can automatically move the destination of washing water sprayed from a washing water injection nozzle.

The basic structure of the present invention to achieve the above object is as follows: A washing water injection nozzle that sprays washing water onto the area to be cleaned of a user seated on a toilet seat, and a water supply that sends washing water to the washing water injection nozzle. and a cleaning water jetting movement means for mechanically driving the cleaning water jetting nozzle from the outside to cause the cleaning water jetting direction to continuously move in a predetermined trajectory. .

In the present invention, with the above configuration, the nozzle movement means gives a continuous movement to the cleaning water jet in a predetermined trajectory, so that the cleaning water jet nozzle removes the dirt attached to the user's part to be cleaned after using the toilet. As a result, there is no need for continuous special operations, and even when the user has diarrhea or is used by a sick or elderly person, the user can sit with his or her hips raised. Since there is no need to continuously move the position, it has various excellent features such as being able to clean the surrounding area easily and comfortably and maintaining high cleaning power.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 3 and 4 show an embodiment of the present invention, and in FIGS. 3 and 4,
The same parts as in FIG. 1 shown in the conventional example are given the same numbers. Reference numeral 12 denotes a support fitting attached to the bottom of the main body case 4, and the shaft 1 is attached to this support fitting 12.
3 rotatably supports the cleaning water injection nozzle 14. Reference numeral 15 denotes a swinging motor supported by a support fitting 12. An eccentric cam 16 is attached to the shaft of this swinging motor 15, and this eccentric cam 16 engages with a swinging follower 17 attached to the cleaning water injection nozzle 14. I'm making it match. Therefore, with this configuration, when the swing motor 15 rotates, the eccentric cam 16
Due to this function, the cleaning water injection nozzle 14 swings back and forth. Reference numeral 18 denotes a hose that communicates the cleaning water injection nozzle 14 with a water supply means (not shown) such as a pump for pumping the cleaning water.

FIG. 5 shows a circuit diagram for controlling the cleaning water jet movement means shown in FIG.
0 is a cleaning operation switch, 21 is a pump motor connected in series with the cleaning operation switch 20, 22
is an automatic return type nozzle movement switch connected to the midpoint between the cleaning operation switch 20 and the pump motor 21, and the swing motor 15 is connected in series with this nozzle movement switch 22. In this circuit configuration, first, when the cleaning operation switch 20 is turned on, the pump motor 21 is started and hot water is jetted from the cleaning water injection nozzle 14 to wash off dirt adhering to the user's part to be cleaned. Next, when the nozzle movement switch 22 is turned on, the swing motor 15 starts, and as shown in FIG.
6 causes the cleaning water jet nozzle 14 to swing back and forth, so that final cleaning can be performed on the front and back of the area to be cleaned. Since the nozzle movement switch 22 is a self-reset type, it is turned on only while the nozzle movement switch 22 is pressed by hand to rotate the swinging motor 15, and when the hand is released, it is turned off and the swinging motor 15 is turned off. Stop rotation.

FIG. 6 is a circuit diagram using a timer, where 23 is a delay type off timer and has a contact 24.
Reference numeral 25 denotes a single-pole, double-throw type cleaning operation switch. The on contact of this cleaning operation switch 25 is connected to the delay-type off timer 23, and the off contact is connected to the swinging motor 15. In this circuit configuration, when the cleaning operation switch 25 is first turned on, the delay type off timer 23 is energized and its contact 24 is turned on. This causes pump motor 2
1 is started and hot water is jetted from a cleaning water jetting nozzle 14 to wash off dirt adhering to the user's part to be cleaned. Next, when the cleaning operation switch 25 is turned off, the swing motor 15 rotates in parallel operation with the pump motor 21, so that the cleaning water injection nozzle 14 is activated by the action of the eccentric cam 16, as shown in FIG. , Perform final cleaning by swinging back and forth. When the delay time has elapsed, the delay type off timer 23 turns off its contact 24 to stop energizing the pump motor 21 and the swing motor 15. With this energization stopped, the injection of cleaning water and the swinging movement of the cleaning water injection nozzle 14 are stopped.

FIG. 7 shows another embodiment of the cleaning water jet movement means, and 26 is a nozzle support fitting, and this nozzle support fitting 26 has a shaft 27, about which the outer cylinder 28 is moved in the front and back direction. It is rotatably supported. 29 is a cleaning water injection nozzle fitted into the outer cylinder 28 so as to be rotatable in the right and left directions toward the front of the toilet, perpendicular to the rotational direction of the outer cylinder 28; 30;
is a hose that communicates the cleaning water injection nozzle 29 with a water supply means (not shown) such as a pump for pressurizing the cleaning water. 31 is an exercise motor; this exercise motor 3
1 has an eccentric camshaft 32 formed on one shaft and a feed screw 33 on the other shaft. Reference numeral 34 denotes a holder for the exercise motor 31. The holder 34 has a guide hole 35, and this guide hole 35 is slidably fitted to a guide portion 36a of the motor support fitting 36, thereby enabling linear movement. The exercise motor 31 also has a feed screw 33 connected to a motor support fitting 36.
By the rotation of the exercise motor 31, the exercise motor 31 and the holder 34 connected thereto are vertically moved in a straight line by the action of the feed screw 33. Reference numeral 37 denotes a follower piece extending from the nozzle 29. A rotating sphere 38 is housed inside the follower piece 37, and a hole is provided in the rotating sphere 38, into which the eccentric camshaft 32 is slid. It can be penetrated freely. The amount of eccentricity of the eccentric camshaft 32 is continuously changed in the axial direction, and the amount of momentum changes from zero to a predetermined value due to the vertical movement of the exercise motor 31. Reference numeral 39 denotes an operating piece attached to the motion motor 31, which operates the reversing switch 40 and the stop switch 41 at the linear motion top dead center of the motion motor 31, and operates the reversing switch 40 and the stop switch 41 at the linear motion bottom dead center of the motion motor 31. switch 40 is operated. In addition, the exercise motor 3
At the top dead center of linear motion 1, the amount of eccentricity is zero at the point of action of the eccentric camshaft 25, and at the bottom dead center, the amount of eccentricity is adjusted to a predetermined value.

FIG. 8 shows a control circuit diagram in the embodiment of FIG. 7, where 42 is the pump motor, 40 is the seventh
The double-pole, double-throw switch for reversing shown in the figure has a, b,
It has c and d contacts. 43 is pump motor 4
2 and an operating hot button switch connected in series with 44
is a relay connected to the middle point between the operation push button switch 43 and the pump motor 42, and this relay 44 has a contact 45. Reference numeral 41 denotes a single-pole double-throw stop microswitch shown in FIG. 7, and this stop microswitch 41 has an NC contact connected to a relay 44. 31 is an exercise motor shown in FIG.

In the circuit configuration shown in FIG. 8, when the operating push button switch 43 is first pressed to turn on, the pump motor 42 is driven. As a result, the cleaning water jetting nozzle 29 shown in FIG. 7 starts jetting hot water toward the user's part to be cleaned in an almost immobile state, and the contact 45 of the relay 44 is turned on to turn on the exercise motor 31. Start it. With this start, the exercise motor 31 starts to descend from the top dead center as shown in FIG. As the operating piece 39 also descends with this descent, the stop micro switch 4
1 is released and switched from NO contact to NC contact. As a result, even if the user releases the operating push button switch 43 and the operating push button switch 43 automatically returns to the OFF state, the pump motor 42 and the relay 44 remain energized. As the exercise motor 31 descends, the amount of eccentricity at the point of action of the eccentric camshaft 32 increases, so the swinging motion of the cleaning water injection nozzle 29 increases continuously.
In this case, the relationship between the movement of the follower piece 37 by the eccentric camshaft 32 and the hot water injection direction from the wash water injection nozzle 29 is determined by the longitudinal component of the momentum of the follower piece 37. 29 causes displacement in the front-rear direction, and similarly, the cleaning water injection nozzle 29 causes displacement in the left-right direction due to the left-right component of the momentum of the follower piece 37. That is, this movement is caused by the eccentric camshaft 32, and as the follower piece 37 expands in a spiral, the point at which the hot water jet reaches the user's area to be cleaned also expands in a similar spiral. do. In addition, by selecting the relevant dimensions on the mechanism,
It is also possible to obtain a spiral jet deformed into an ellipse. When the exercise motor 31 descends and its momentum reaches a predetermined value, the action piece 39 at the bottom dead center causes the reversing double-pole double-throw switch 40 to switch the contact a to the contact b, and the contact c
is switched to the contact d, so the motion motor 31
reverses and moves in an upward direction. As a result, the swirling motion of the hot water jet is gradually reduced, and when it becomes almost stationary, the motion motor 31 reaches the top dead center. In the double-throw switch 40, the contact b is switched to the contact a, the contact d is switched to the contact c, and the stop micro switch 41 is switched to the NO contact. As a result, the pump motor 42 and the exercise motor 31 stop and enter a standby state.

That is, in the embodiment shown in FIGS. 7 and 8, when the operating push button switch 43 is operated once, the cleaning water injection nozzle 29 expands its oscillating motion from a fixed point injection to a gradually spiral injection. When the spiral reaches a predetermined outer diameter, it then reverses, reduces its motion, returns to fixed point injection, and stops, forming a cyclic motion. Therefore, by repeating this cycle several times, thorough cleaning can be achieved.

Furthermore, when the oscillating motion of the cleaning water injection nozzle 29 is deenergized and stopped, it is configured to always stop at a fixed point, so that the next user can clean at a fixed point when cleaning. This feature allows the user to start cleaning with peace of mind without causing any confusion.

Although it is possible to apply a fluid element as a means of drawing a predetermined trajectory in the direction of jetting cleaning water, there are problems in that it cannot be moved freely and in the time required to move it, and the configuration of the present invention solves this problem. It is excellent. Specifically, in the embodiment of the present application, a stable periodic motion determined by the rotation speed of the motor is obtained regardless of the amount of washing water, and the period can be easily varied, but when a fluid element is applied, the amount of washing water is If it increases, the cycle will automatically become faster, and it is extremely difficult to change the cycle. Furthermore, it is even more difficult to stop at a fixed point or to draw a trajectory that gradually expands and contracts in a spiral shape, as shown in the second and subsequent claims, and the controllability is inferior to that of the present invention.

As described above, according to the present invention, there is provided a cleaning water jetting movement means that mechanically drives the cleaning water jetting nozzle from the outside to cause the cleaning water jetting direction to continuously move in a predetermined trajectory. Because of this, the cleaning water jetting nozzle allows the cleaning water jetting nozzle to intensively wash away the dirt adhering to the user's area to be cleaned after using the toilet, and also to clean the surrounding area. As a result, there is no need for continuous special operations, and there is no need to lift the waist and continuously move the sitting position even when using the device in case of diarrhea, sick people, or the elderly. It has various excellent features, such as being able to perform comfortable cleaning, including cleansing, and maintain high cleaning power, as well as having a temporally stable cycle of the trajectory it draws and excellent controllability of the trajectory.
