[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device having a local washing function, and more particularly to a nozzle device capable of accurately setting a washing point of a nozzle for discharging washing water.

[0002]

2. Description of the Related Art A sanitary washing apparatus having a local washing function is provided by:
In general, a structure in which hot water is sprayed toward a local area by a nozzle device is shown in FIG.

In the figure, a casing 2 of a sanitary washing device is fixed to a toilet body 1, and a toilet seat 6a and a toilet lid 6b are attached to the casing 2 so as to be openable and closable. Casing 2
Is provided with a tank for heating the washing water, a hot air fan for drying, and a control unit. The operation of each function unit is performed by an operation panel 9 provided on the side surface of the casing 2. Also,
A nozzle device is incorporated at substantially the center of the casing 2, and a nozzle body 7a for ejecting washing water is provided so as to be able to reciprocate between its storage position and the washing position.

[0004] The nozzle body 7a is provided with two types of jet holes at the tip thereof at intervals in the axial direction to be used for anal cleaning and bidet use. The advance to the washing position is set to have a longer stroke when used for a bidet than for the anal washing position. Such an operation of the nozzle body 7a is performed by means such as a drive motor, and is set at a fixed cleaning position. In some cases, the nozzle is moved in the axial direction at the cleaning point of the nozzle body 7a in order to widen a portion to be exposed to the cleaning water.

[0005]

However, the cleaning position of the nozzle body 7a is determined, for example, according to a standard local position when a person sits on the toilet seat 6a. For this reason, when the body is large or small, such as a child, the washing water may come off the local part. Also,
Even when the toilet seat 6a cannot be seated in the correct posture as in the case of an elderly person or a physically handicapped person, appropriate cleaning cannot be performed similarly.

[0006] Further, during the washing, it is possible to know only which part of the body the washing water actually hits by touch. For this reason, in the case of a person with a physical disability such as lower body paralysis, it is not possible to know whether the washing water is properly applied to the local area and the washing is performed, and the washing may end with insufficient washing. There are many.

The problem to be solved in the present invention is to make it possible to easily check the cleaning points, to improve the usability, and to be able to perform the cleaning sufficiently.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a sanitary washing apparatus provided with a nozzle for local washing, and an image pickup head for picking up an injection position of washing water from the nozzle, and an image pickup head. And a monitor for displaying the selected image.

[0009]

The position of the washing water from the nozzle relative to the point to be washed is photographed by the imaging head, and this can be confirmed by the monitor. For this reason, it is possible to know the injection point of the cleaning water from the nozzle while looking at the monitor, and it is possible to perform cleaning with the cleaning water reliably applied to the point to be cleaned.

[0010]

FIG. 1 is a perspective view showing an example of a sanitary washing apparatus provided with a monitor for washing on a wall.

In FIG. 1, a casing 2 for accommodating a sanitary washing device having a local washing function is integrated with a toilet body 1. The casing 2 is composed of a base (to be described later) fixed to the toilet body 1 and three parts, an upper casing 4 and a lower casing 5, which are respectively arranged above and below the base and integrated. A toilet seat 6a and a toilet lid 6b are attached to the front end of the front portion of the upper casing 4, respectively.

Inside the upper casing 4, a washing water tank (not shown) for feeding washing water to the toilet body 1 is housed, and a nozzle device 7 for local washing, a hot water tank (not shown), and a nozzle device are provided. An imaging head 8 for confirming a washing point at the time of washing by the washing machine 7 is incorporated.

FIG. 2 is a schematic diagram showing a supply system of the washing water to the nozzle device 7, which comprises a valve unit 10 having an on-off valve and a flow regulating valve function, a hot water tank 11, and a controller 12. Between the nozzle device 7 and the nozzle device 7, a flow rate adjustment switching unit 13 is incorporated. Note that the function of the flow rate adjustment switching unit 13 may be provided to the valve unit 10. The operation of the nozzle device 7, the setting of the washing position, the setting of the hot water temperature by the hot water tank 11, and the operation of the valve unit 10 and the flow rate adjustment switching unit 13 are performed by the operation panel 9 provided in the casing 2. The operation panel 9 has an initial operation switch 9a for confirming a cleaning point using the imaging head 8, a cleaning switch 9b for discharging water from the nozzle device 7, and a cleaning stop in order to perform cleaning by the nozzle device 7. And a stop switch 9c for returning the nozzle device 7 to the original position, and a switch for each functional unit.

The nozzle device 7 includes a nozzle body 7a that reciprocates between a storage position in the casing 2 and a washing position, and a nozzle head 7b having a nozzle for washing water provided at an end of the nozzle body 7a. It is a thing. And two washing water flow paths are formed in the nozzle body 7a, and two supply pipes 16 and 17 from the flow rate adjustment switching unit 13 are connected to the inflow portions 14 and 15, respectively. The nozzle head 7b has two types of ejection holes used for anal cleaning and a bidet, which are respectively connected to two channels in the nozzle body 7a.

FIG. 3 is a left side view showing details of the nozzle device 7, and FIG. 4 is a right side view showing a drive system.

In the drawing, a base 20 of a nozzle body 7a is provided inside a casing 2, and a concave curved slide surface 21 for receiving the lower surface of the pipe-shaped nozzle body 7a is formed on the base 20. Further, a cleaning chamber 22 for washing the nozzle head 7b of the nozzle body 7a is provided at the tip of the slide surface 21.

Further, a drive motor 23 for reciprocating the nozzle body 7a is fixed to the base 20, and a drive pulley 24 is provided on an output shaft thereof. This drive pulley 24
, A timing belt 25 is wound therearound, and two pulleys 26 and 27 provided on the base 20 and a tension pulley 28 are provided.
The timing belt 25 is looped around. on the other hand,
A clamp 19 for grasping the timing belt 25 is provided on the base end side of the nozzle body 7a, and the nozzle body 7a is moved as the timing belt 25 runs.

As shown in FIG. 5, the imaging head 8 disposed near the nozzle device 7 is for photographing a local washing point by the nozzle body 7a and displaying it on a monitor 29. The monitor 29 is provided on the wall of the toilet (shown in FIG. 1) so that it can be viewed while sitting on the toilet seat 6a, or is incorporated in an appropriate position of the upper casing 4 near the operation panel 9, and the switch is operated while looking at the monitor 29. It can be so.

The imaging head 8 is in the form of a pipe having a light receiving surface 8a incorporated at the tip thereof, and is connected to a monitor 29 by a cable 8b. Then, the imaging head 8 is moved independently of the nozzle body 7a, or is integrated with the nozzle body 7a to photograph a cleaning point.

FIG. 6 is a schematic diagram showing a drive system of the imaging head 8 independent of the movement of the nozzle body 7a. Like the nozzle body 7a, the imaging head 8 is slidably incorporated in a guide 8c and has a motor. It is mechanically connected to the output shaft of 8d. In this configuration, the nozzle main body 7a and the imaging head 8 advance from the storage position of (a) in the drawing by the respective drive motors 23 and 8d as shown in (b) of the drawing. In addition, as shown in FIG.
The operation of returning the image pickup head 8 alone to the storage position while leaving the image pickup head at the cleaning position is possible.

FIG. 7 shows an example in which the imaging head 8 is integrated with the nozzle body 7a by the fixture 8e, and the imaging head 8 is moved together with the nozzle body 7a. In this case, when the nozzle main body 7a advances to the cleaning position as shown in FIG. 7B, the imaging head 8 also moves toward the cleaning position at the same time, and also returns to the nozzle body 7a at the time of storage.

Here, the amount of movement of the nozzle body 7a to the cleaning position is proportional to the rotation of the output shaft of the drive motor 23. For this reason, a position setting switch 9d is provided on the operation panel 9 so that the amount of rotation of the output shaft of the drive motor 23 and the direction of the rotation direction can be easily changed, and the position setting switch 9d controls the drive motor 23 via the controller 12. By controlling the movement of the output shaft, the amount of movement of the nozzle body 7a can be changed.

In the above configuration, cleaning with the drive system of the imaging head 8 in the case of FIG. 6 is performed in the following manner.

First, when the initial operation switch 9a of the operation panel 9 is turned on, the drive motor 23 and the motor 8d are operated, and the nozzle body 7a and the imaging head 8 are advanced to the cleaning position as shown in FIG. And stop at a preset position. At this time, the light receiving surface 8a of the imaging head 8 displays the cleaning point on the monitor 29, and checks, for example, whether the point to be cleaned is near or apart from the mark indicating the optimum cleaning point on the screen. If the user is away, the posture is changed on the toilet seat 6a, or the output shaft of the drive motor 23 is further moved by the position setting switch 9d, and the nozzle head 7b is set again so as to appropriately point the washing point.

After the cleaning point by the nozzle head 7b is confirmed in this way and set at an appropriate position, the cleaning switch 9b is turned on. Thereby, the washing water is supplied to the nozzle body 7.
Simultaneously, the motor 8d is operated to return the imaging head 8 to its storage position as shown in FIG. Therefore, if the timing is set so that the cleaning water is ejected from the nozzle head 7b after the imaging head 8 is stored, the imaging head 8 is not exposed to cleaning water, dirty water, or the like.

Since the position of the washing water from the nozzle head 7b is adjusted in the previous stage, the point to be washed is accurately directed, and optimal washing is possible. And the stop switch 9
When c is pressed, the output shaft of the drive motor 23 rotates in the reverse direction and returns the nozzle body 7a to its storage position as shown in FIG.

When the cleaning switch 9b is turned on without turning on the initial operation switch 9a, the motor 8d is not operated and the imaging head 8 is prevented from moving forward. Therefore, when imaging is not required, normal pattern cleaning can be performed.

In the drive system of the imaging head 8 shown in FIG.
When the initial operation switch 9a is turned on, the imaging head 8 moves together with the nozzle body 7a to the cleaning point side as shown in FIG. After the cleaning point is reached, the position of the cleaning point photographed by the imaging head 8 is monitored by the monitor 29 as in the case of FIG.
When there is a displacement, the drive motor 23 is operated by the position setting switch 9d to adjust the position of the nozzle body 7a. After this adjustment, when the cleaning switch 9b is turned on, the cleaning water is jetted from the nozzle head 7b, and the cleaning can be performed by applying the cleaning water accurately to the point to be cleaned. When the cleaning is completed, the stop switch 9c is pressed, and the nozzle body 7a and the imaging head 8 return to the original storage positions as shown in FIG.

As described above, when the nozzle body 7a is advanced to the cleaning position, the position where the cleaning water is jetted from the nozzle head 7b can be displayed on the monitor 29 by the imaging head 8. Therefore, if the injection position is shifted from the point to be cleaned,
The cleaning water can be reliably applied to the point to be cleaned by correcting the position of the nozzle head 7b, and accurate cleaning can be performed without wasting the cleaning water.

[0030]

According to the present invention, the jetting direction and position of the washing water from the nozzle device can be photographed by the image pickup head and can be confirmed on the monitor. You can check if there is. For this reason, if the jetting position of the washing water is shifted, if the body can be moved or the drive system of the nozzle device can be operated, the position of the washing point is corrected, and the point to be washed is moved to the jetting position of the washing water. Can be adjusted to Therefore, the washing water is surely washed away at the point to be washed, so that the washing water can be always used in a sanitary manner without wasting the washing water unnecessarily or leaving no washing.
