Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning apparatus for realizing a large amount of water saving as compared with a conventional cleaning water amount while maintaining a cleaning power and a feeling of cleaning.

[0002]

2. Description of the Related Art FIGS. 11 (a) and 11 (b) show a local cleaning nozzle of a conventional local cleaning apparatus, wherein 3 is a cleaning nozzle body, 32 is a discharge hole, and 33 is a flow path through which cleaning water flows. It is. The cleaning water supplied from a cleaning water supply unit (not shown) is discharged from the discharge hole 32 toward the local part through the flow path 33. The number of discharge holes includes one provided in FIG. 11 (a) and a plurality provided in FIG. 11 (b). It can be used properly depending on the difference between washing and vaginal washing.

The total area of the discharge holes of the conventional discharge holes 27 is 1.5 square mm or more in the case of anal washing, and 2.3 square mm or more in the case of vaginal washing. In general, the washing nozzle and the discharge hole are changed by vaginal irrigation, and the vaginal irrigation generally has a larger total discharge hole area of the irrigation nozzle than the anal irrigation. The reason why the total area of the discharge holes of the washing nozzle is larger in the vaginal washing than in the anal washing is that there is a strong demand for gentle washing over a wide area in the vaginal washing compared to the anal washing.

[0004]

From the viewpoint of water shortage and energy saving in recent years, it is necessary to work on water saving in daily life in general. Even in the local cleaning device, it is desirable to reduce the amount of instantaneous discharge water to save water.

[0005] In the case of a local cleaning device, it is general to wash the device with warm water. In general, the more the instantaneous discharge amount can be reduced and the water can be saved, the more compact the heat exchanger for warm water can be. Since the local cleaning device can be made compact, not only can the cost be reduced, but also the degree of freedom in design can be increased, and a local cleaning device with excellent design at low cost can be provided to consumers. Furthermore, if the instantaneous discharge water amount can be reduced and water can be saved, it is possible to reduce the electric power consumption of the heater for making the hot water, thereby saving electricity bills.

However, the total area of the discharge holes 27 of the local cleaning nozzle of the conventional local cleaning device is 1.5 square mm or more for anal cleaning and 2.3 square meters for vaginal cleaning.
m or more, reducing the instantaneous water discharge to save water will slow down the flow velocity, increase the cleaning time, and cause problems such as remaining dirt etc. in the local area. I can't get it.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. Even when the instantaneous discharge amount is reduced for saving water, not only does the cleaning time become long, but also there is no problem that dirt and the like remain locally. It is an object of the present invention to provide a local cleaning device which can ensure a comfortable cleaning feeling.

[0008]

Means, actions and effects for solving the problem.
In a local cleaning apparatus for cleaning an anus by discharging anal cleaning water from a discharge hole provided in a nozzle, a discharge effective total area of the discharge hole of the nozzle is less than 1.5 square mm. Therefore, even when the amount of instantaneous discharge water is reduced (water is saved), the flow rate of the cleaning water can be increased, so that not only there is no problem such as a longer cleaning time and there is no problem that dirt and the like remain in a local area, but also the cleaning water flow rate can be increased. Even if the washing water flow rate is increased, the instantaneous discharge water amount can be reduced without weakening the washing feeling, so that a comfortable washing feeling can be secured without increasing the energy of the washing water hitting a local portion more than necessary. . Further, if the total effective discharge area of the discharge holes of the nozzles is less than 1.25 square mm, even if the instantaneous discharge water amount is further reduced (further saving water),
Furthermore, since the washing water flow rate can be increased, sufficient washing power can be secured, and even though the washing water flow rate has been further increased, the instantaneous discharge water amount can be further reduced, so that the energy of the washing water hitting a local area is unnecessarily large. It is possible to secure a comfortable washing feeling without doing. Further, if the total effective discharge area of the discharge holes of the nozzles is less than 1 mm 2, even if the instantaneous discharge water amount is greatly reduced (water is largely saved), the flow rate of the washing water can be greatly increased. Cleaning power can be secured, and the instantaneous discharge water volume can be significantly reduced even though the cleaning water flow rate has been significantly increased, so that the energy of the cleaning water hitting a local area is not increased unnecessarily, and a comfortable cleaning feeling Can be secured.

According to a second aspect of the present invention, there is provided a trajectory control unit for controlling the anal irrigation water so as to draw a predetermined trajectory, so that the discharge effective total area of the discharge holes is less than 1.5 square mm. Nevertheless, the energy of the washing water can be effectively dispersed in the washing area, so that the user can sufficiently wash the area to be washed, without having to frequently move the body (buttocks). There is no problem of washing feeling such as pain. The effect is particularly great when the number of discharge holes is small or one. Furthermore, since the local area in the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area in the local area, and the feeling of cleaning is further improved by the intermittent stimulation.

According to a third aspect of the present invention, the discharge holes are formed as an aggregate of a plurality of discharge holes, so that the discharge effective total area of the discharge holes is less than 1.5 square mm. The discharge holes can be dispersed so that the cleaning area can be secured, and the energy of the cleaning water can be effectively dispersed within the cleaning area, so that the area that the user wants to clean can be sufficiently cleaned, and the body is frequently enlarged. There is no need to move the (buttocks), and there is no problem of washing feeling such as pain.
Furthermore, it is only necessary to disperse the ejection holes in order to secure a cleaning area, and the present invention can be implemented with a simpler structure than in the case where a trajectory control unit is provided.

According to a fourth aspect of the present invention, the effective discharge area of each discharge hole is less than 0.35 square mm, so that the washing water can be evenly dispersed within the washing area. Since the energy of the washing water can be evenly distributed in the washing area, the area that the user wants to wash can be sufficiently washed, and there is no need to frequently move the body (buttocks), and the feeling of washing is painful. No problem occurs. If the area of each discharge hole is less than 0.3 square mm, the washing water can be more evenly dispersed within the washing area, and the energy of the washing water can be more evenly dispersed within the washing area. It can clean the area that the user wants to clean, and often makes the body (buttocks) bigger
There is no need to move, and there is no problem of washing feeling such as pain. Also, the area of each discharge hole is 0.2
If it is less than square mm, the washing water can be almost continuously dispersed in the washing area, and the energy of the washing water can be almost continuously dispersed in the washing area. It can be washed, and there is no need to frequently move the body (buttock), and there is no problem of painful washing feeling.

According to a fifth aspect of the present invention, there is provided an air mixing means for mixing air into the anal cleaning water discharged from the discharge hole. Reduce (more water saving)
As the washing water flow rate can be increased, the washing power can be secured, and even though the washing water flow rate has been increased, the instantaneous discharge water amount can be further reduced, so that the energy of the washing water hitting a local area can be increased more than necessary. And a comfortable feeling of washing can be secured. That is, it is possible to further save water while achieving both a sufficient washing power and a comfortable washing feeling.

According to a sixth aspect of the present invention, there is provided an intermittent discharge means for intermittently discharging the anal cleaning water discharged from the discharge hole, so that even if the flow rate of the cleaning water is increased, one cycle of intermittent cleaning is provided. The instantaneous discharge water amount can be further reduced (further saving water) according to the wash water discharge time or the wash water discharge amount, and the cleaning water flow rate can be increased, so that the cleaning power can be secured and the wash water flow rate has been increased. Nevertheless, the amount of instantaneous discharge water can be further reduced, so that the energy of the wash water hitting a local portion is not increased unnecessarily, and a comfortable washing feeling can be secured. Furthermore, since the local area in the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area in the local area, and the feeling of cleaning is improved by the intermittent stimulation. That is, it is possible to further save water while achieving both a sufficient washing power and a comfortable washing feeling.

According to a seventh aspect of the present invention, there is provided a local cleaning apparatus for cleaning a vagina by discharging vaginal washing water from a discharge hole provided in a nozzle, wherein a discharge effective total area of the discharge hole of the nozzle is less than 2.3 square mm. The feature is that even if the amount of instantaneous discharge water is reduced (water saving), the flow rate of the cleaning water can be increased, so that there is not only a problem that the cleaning time is long and there is no problem that dirt and the like remain in the local area, and the cleaning is performed. As the water flow speed can be increased, the washing feeling does not weaken, and even though the washing water flow speed is increased, the instantaneous discharge water amount can be reduced, so that the energy of the washing water hitting a local area is not increased unnecessarily and is comfortable. A clean feeling can be secured. Further, when the total effective discharge area of the discharge holes of the nozzle is less than 2 mm 2, the instantaneous discharge water amount is further reduced (further water saving).
Even in this case, the washing water flow rate can be further increased to secure sufficient washing power, and even though the washing water flow rate is further increased, the instantaneous discharge water amount can be further reduced, so the energy of the washing water hitting a local area is required A comfortable washing feeling can be secured without increasing the size. If the total effective discharge area of the discharge holes of the nozzle is less than 1.7 square mm, even if the instantaneous discharge water amount is greatly reduced (water is largely saved), the washing water flow rate can be greatly increased. As a result, sufficient washing power can be ensured, and even though the washing water flow rate has been significantly increased, the instantaneous discharge amount can be significantly reduced, so that the energy of the washing water hitting a local area is not increased unnecessarily, and comfortable washing is performed. A feeling can be secured.

According to the present invention, the trajectory control section for controlling the vaginal washing water so as to draw a predetermined trajectory is provided, so that the total effective discharge area of the discharge holes is less than 2.3 square mm. Nevertheless, since the energy of the washing water can be effectively dispersed in the washing area, the area that the user wants to wash can be sufficiently washed, and the body (vaginal) does not need to be moved frequently and it is painful. There is no occurrence of such a problem of the washing feeling. The effect is particularly great when the number of discharge holes is small or one. Furthermore, since the local area of the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area of the local area. Therefore, the cleaning sensation is further improved by the intermittent stimulation.

According to a ninth aspect of the present invention, since the discharge holes are formed as an aggregate of a plurality of discharge holes, the discharge effective total area of the discharge holes is less than 2.3 square mm. The discharge holes can be dispersed so that the cleaning area can be secured, and the energy of the cleaning water can be effectively dispersed within the cleaning area, so that the area that the user wants to clean can be sufficiently cleaned, and the body is frequently enlarged. (Vagina) does not need to be moved,
There is no problem of washing feeling such as pain. Furthermore, it is only necessary to disperse the ejection holes in order to secure a cleaning area, and the present invention can be implemented with a simpler structure than in the case where a trajectory control unit is provided.

According to a tenth aspect of the present invention, the discharge effective area of each discharge hole is less than 0.28 square mm, so that the cleaning water can be evenly dispersed within the cleaning area. Since the energy of the washing water can be evenly distributed within the washing area, the area that the user wants to wash can be sufficiently washed, and the body (vaginal) does not need to be moved frequently and the feeling of pain such as pain is felt. No problems occur. If the area of each discharge hole is less than 0.22 square mm, the washing water can be more evenly dispersed within the washing area, and the energy of the washing water can be more evenly dispersed within the washing area. It can clean the area that the user wants to clean, and often the body (vaginal)
There is no need to move, and there is no problem of washing feeling such as pain. Further, each discharge hole area is set to 0.1
If it is less than 8 square mm, the washing water can be almost continuously dispersed in the washing area, and the energy of the washing water can be almost continuously dispersed in the washing area. It is not necessary to frequently move the body (vaginally), and there is no problem of a feeling of washing such as pain.

The eleventh aspect of the present invention is characterized in that an air mixing means for mixing air into the vaginal washing water discharged from the discharge hole is provided. Reduce (more water saving)
As the washing water flow rate can be increased, the washing power can be secured, and even though the washing water flow rate has been increased, the instantaneous discharge water amount can be further reduced, so that the energy of the washing water hitting a local area can be increased more than necessary. And a comfortable feeling of washing can be secured. That is, it is possible to further save water while achieving both a sufficient washing power and a comfortable washing feeling.

According to a twelfth aspect of the present invention, there is provided an intermittent discharge means for intermittently discharging the vaginal washing water discharged from the discharge hole. The instantaneous discharge water amount can be further reduced (further saving water) according to the wash water discharge time or the wash water discharge amount, and the cleaning water flow rate can be increased, so that the cleaning power can be secured and the wash water flow rate has been increased. Nevertheless, the amount of instantaneous discharge water can be further reduced, so that the energy of the wash water hitting a local portion is not increased unnecessarily, and a comfortable washing feeling can be secured. Furthermore, since the local area in the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area in the local area, and the feeling of cleaning is improved by the intermittent stimulation. That is, it is possible to further save water while achieving both a sufficient washing power and a comfortable washing feeling.

[0020]

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that there is no significant difference between anal washing and vaginal washing in terms of sufficiently washing away dirt and the like (detergency). Anal washing and vaginal washing differ only in the user's preferred washing area and optimal washing water flow rate, and may be designed accordingly. Since there is no need to make a distinction, the following embodiments will be described without particular distinction.

FIG. 1 is a schematic structural view showing an embodiment of the present invention, and FIG. 2 is a perspective view of a local cleaning nozzle. First, the path of the washing water will be described. When the washing water is supplied from the washing water supply means 1, the washing water flows into the washing nozzle 3 through the heat exchanger 2 which makes the washing water warm, and is discharged from the discharge hole 31 to be discharged from the local portion. Washing is performed. Here, the discharge hole 31 has a smaller discharge effective total area than in the past. The cleaning water supply means 1 is composed of a flow control valve 12 and a water stop valve 11, and it is necessary to attach a water pump 13 when the tap water pressure for discharging is insufficient or when the tap water pressure is not used. The control unit 6 includes a cleaning water supply control unit 61 for controlling the cleaning water supply unit 1 and a heat exchanger control unit 62 for controlling power supply to the heat exchanger 2, and is provided with a switch unit (not shown) for the user. A signal from an operation or the like is transmitted to the control unit 6, and the user can perform desired cleaning.

In the above configuration, the operation of this embodiment will be described. Washing water is supplied from the washing water supply means 1 by a user's switch operation or the like. The cleaning water discharged
Since the discharge is performed from the discharge holes 31 having a smaller discharge effective total area compared to the conventional case, even when the instantaneous discharge amount is reduced (water saving), the discharge can be performed at a higher cleaning water speed than before, and the cleaning time can be reduced. Not only there is no problem that the cleaning water becomes longer or waste remains in the local area, but also the washing water flow rate can be increased, so the feeling of washing is not weakened, and the instantaneous discharge water amount is reduced despite the increased washing water flow rate. Since it is possible, it is possible to secure a comfortable washing feeling without increasing the energy of the washing water hitting a local portion more than necessary.

Next, a case where a trajectory control unit is provided will be described. Since the purpose of the trajectory control unit is to control the cleaning water to draw a predetermined trajectory, as shown in FIG. 3, the trajectory control unit 41 may be provided at the end of the water passage, and controls the movement of the cleaning nozzle 3. Therefore, the trajectory control unit 41 is
It may be provided outside. Further, the control unit 6 includes a trajectory control unit control unit 64, and the user operates the switch unit to perform the operation.
The desired washing can be performed.

As shown in FIG. 3, the configuration of the trajectory control unit may be such that the discharge motor 31a rotates the discharge hole 31 to control the cleaning water so as to draw a predetermined trajectory. Becomes spiral. Further, as shown in FIG. 4 (a), the cleaning nozzle 3 itself may be rotated by a nozzle rotating motor 41b, and as shown in FIG. A predetermined trajectory may be drawn by a combination of the front, rear, left and right movements of the cleaning nozzle 3 by the drive motor 41d. In addition, since the predetermined trajectory that satisfies the present invention may be swung, a fluid element may be used as a trajectory control unit as shown in FIG. Thus, the cleaning water may be oscillated by transmitting the vibration of the vibration motor 41e so that the discharge holes vibrate. Further, a configuration in which these trajectory control units are combined may be employed. For example, as shown in FIG. 6, there is a case where the nozzle is moved left and right by a motor, and the cleaning water is swung back and forth by a fluid element.

By making the configuration of the trajectory control section as described above, the energy of the cleaning water can be effectively dispersed within the cleaning area, even though the total effective discharge area of the discharge holes is smaller than the conventional one. Therefore, the area that the user wants to clean can be sufficiently cleaned, so that the user does not need to frequently move his / her large body, and there is no problem of painful cleaning feeling. Furthermore, since the local area in the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area in the local area, and the feeling of cleaning is further improved by the intermittent stimulation. The effect is particularly great when the number of discharge holes is small or one, but the effects of the present invention can be satisfied without being limited to the number of discharge holes.

Further, the frequency of the intermittent stimulation can be changed by changing the rotation speed and the oscillating frequency of the washing water. Therefore, by controlling the rotation speed and the oscillating frequency of the washing water, the local area As a result, it is possible to control a stimulating feeling that the washing water is intermittently applied. For example, when the user does not like the intermittent stimulation and likes the continuous feeling of washing, the rotation motor 41a is controlled to be driven at a high speed,
In order to rotate the cleaning nozzle 3 at a high speed, a nozzle rotation motor 41b and a nozzle front-rear drive motor 41c
And the nozzle left / right drive motor 41d is controlled to drive at high speed, and the oscillating motor * is controlled to drive at high speed in order to cause the cleaning nozzle 3 to oscillate at high speed. The discharge of water can be controlled so as to draw a predetermined trajectory at a high speed, and the user can obtain a continuous washing feeling. In particular, if a predetermined locus is drawn at a high speed at a frequency of the intermittent stimulus that is equal to or higher than the threshold value at which the local part senses the intermittent stimulus, the effect of the continuous stimulus feeling is remarkable. Conversely, when strong intermittent stimulation is desired, the rotation motor 41a, the nozzle rotation motor 41b, the nozzle front-rear drive motor 41c, and the nozzle left-right drive motor 41d
Also, by controlling the rocking motor * to be driven at a low speed, the user can obtain a strong intermittent stimulation. Further, by controlling the rotation speed and the oscillating frequency of the washing water so as to change with time, it is possible to sufficiently cope with the user's various washing feeling preferences.

Next, a case where the discharge holes are formed as an aggregate of a plurality of discharge holes will be described. An aggregate of a plurality of discharge holes
The configuration is as shown in FIG. 7, and the discharge of the cleaning water is in a shower shape. With the configuration shown in FIG. 7, the discharge holes can be dispersed so as to secure a cleaning area, even though the discharge effective total area of the discharge holes is smaller than the conventional area, and the energy of the cleaning water can be reduced within the cleaning area. Since it is possible to disperse the medicine, it is possible to sufficiently clean the area that the user wants to wash, and it is not necessary to frequently move the body, and no trouble such as pain is caused in the washing feeling. Also, the smaller the discharge hole, the greater the effect of dispersing the wash water in the wash area, but
Since small foreign matter contained in the washing water tends to be clogged, it is necessary to provide a finer strainer in the water passage as the discharge hole becomes smaller. Furthermore, it is only necessary to disperse the ejection holes in order to secure a cleaning area, and an electric drive source is not particularly required, and the present invention can be implemented with a simple structure as compared with the case where a trajectory control unit is provided.

Next, a case where an air mixing means for mixing air into the washing water is provided will be described. FIG. 8 is a configuration diagram in the case where an air mixing unit is provided. Air is mixed into the cleaning water by the air mixing unit 42a. The configuration of the air mixing section 42a may be a configuration in which air is self-sucked by the ejector effect, or an air pump 42b may be provided to perform forced mixing. In addition, the aeration part 42a is preferably located between the heat exchanger 2 and the discharge hole * in the water passage, but the closer to the discharge hole *, the less likely the air aeration state is to be affected by the water passage. When the air pump 42b is provided, it is not necessary to increase the capacity of the air pump 42b more than necessary.
Further, the control unit 6 is provided with an air mixing control unit 65, so that the user can perform desired cleaning by operating a switch unit or the like.

By adopting the configuration shown in FIG. 8, even when the flow rate of the washing water is increased, the amount of instantaneous discharge water can be further reduced (to further save water) by air mixing, and the washing water flow rate can be increased, so that the washing power is secured. Even if the flow rate of the washing water is increased, the instantaneous discharge water amount can be further reduced, so that the energy of the washing water hitting a local part is not increased unnecessarily, and a comfortable washing feeling can be secured. That is, it is possible to further save water while achieving both a sufficient washing power and a comfortable washing feeling. Also, if a porous body is used for air mixing, the mixed air becomes fine bubbles, and a softer feeling of washing can be obtained.

Next, a case where an intermittent discharging means for intermittently discharging the cleaning water is provided will be described. FIG. 9A is a configuration diagram in the case where the intermittent discharge means 43 is provided, and the discharge of the washing water is intermittent as shown in FIG. 9A or pulsating as shown in FIG. Shape. As shown in FIG. 11, if the intermittent discharge means 43 is provided with a rotary on-off valve (disc valve), intermittent water discharge can be easily performed by rotation of the intermittent motor 43a. In this case, the intermittent frequency can be controlled by the number of revolutions of the disc valve, so that it can be easily changed from a high intermittent frequency to a low intermittent frequency. Further, as a configuration of the intermittent discharge means, an electromagnetic valve for simply turning on and off the water passage may be provided. The position where the intermittent discharge means 43 is arranged is such that the downstream side of the water passage has better followability of the intermittent discharge,
The position immediately before the discharge hole 31 is best. If the hot water storage unit 5 is provided between the heat exchanger 2 and the intermittent discharge means 43, the heat exchanger 2
The time variation of the washing water passing through the heat exchanger 2 can be reduced, so that the temperature control of the washing water in the heat exchanger 2 becomes easy.

With the configuration shown in FIG. 9, even when the flow rate of the cleaning water is increased, the instantaneous discharging water amount is further reduced according to the cleaning water discharging time or the cleaning water discharging amount in one intermittent cycle (further water saving). As the washing water flow rate can be increased, the washing power can be secured, and even though the washing water flow rate has been increased, the instantaneous discharge water amount can be further reduced, so that the energy of the washing water hitting a local area can be increased more than necessary. And a comfortable feeling of washing can be secured. Furthermore, since the local area in the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area in the local area, and the feeling of cleaning is improved by the intermittent stimulation. That is, it is possible to further save water while achieving both a sufficient washing power and a comfortable washing feeling.

Further, since the frequency of the intermittent stimulation can be changed by changing the intermittent frequency of the washing water, the intermittent frequency of the washing water is controlled so that the washing water is intermittently viewed from a local local range. Can be controlled. For example, I do n’t like intermittent stimulation,
If a continuous feeling of washing is desired, the intermittent frequency of the washing water can be increased by controlling the intermittent motor 43a to drive at a high speed or controlling the solenoid valve to turn on and off at a high speed. Can be controlled to
The user can obtain a more continuous washing feeling. In particular, if the cleaning water is discharged at a frequency of the intermittent stimulus equal to or higher than the threshold value at which the local part senses the intermittent stimulus, the effect of the continuous stimulus sensation is remarkable. Conversely, when strong intermittent stimulation is desired, the user can obtain strong intermittent stimulation by controlling the rotation of the intermittent motor 43a and the on / off of the electromagnetic valve to be driven at a low speed. Further, by controlling the intermittent frequency of the washing water to change with time, it is possible to sufficiently cope with the user's various tastes of the washing feeling.
