A hot water flush toilet seat having a cleaning nozzle device is useful in terms of comfort during use. However, does the conventional nozzle device have a single nozzle portion? In the case of a plurality of nozzles that are driven simultaneously in a single state or separately, the driving unit is arranged in the same plane as the plurality of nozzles.

For this reason, conventionally, a plurality of nozzles are individually driven to enable separate use of the posterior wash and the bidet wash, thereby improving convenience and maintaining the cleanliness of the nozzles. When one nozzle is used, the other cannot be kept clean by keeping it in the retracted initial position. It is very difficult to install a drive device in the same plane as, and even if this is possible, there are large mechanical restrictions, a simple structure, and it is possible to accurately adjust the nozzle position as its performance. Was extremely difficult.

Therefore, the present invention solves the problems of the prior art as described above, and it is possible to separately drive a plurality of cleaning nozzles, and the driving is simple and accurate. It is an object of the present invention to provide a drive device for a new cleaning nozzle device that can adjust the position.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in more detail below with reference to examples. FIG.
FIG. 1 is a plan view of an essential part showing an example of the present invention. For example, as illustrated in FIG. 1, the washing nozzle device for a warm water washing toilet seat according to the present invention is, first, for bidet washing which is independently movable. It has a plurality of nozzles including a nozzle (1), a posterior washing nozzle (2), and cylinders (3) and (4) connected to each, and a cylinder slide base (5). The cylinders (3) and (4) are guided forward by the cylinder slide base (5) (to the left in FIG. 1).
Or, it is moved backward or returned to the initial position (state of FIG. 1). Warm water is ejected from the tip of the nozzle in a state of moving forward and projecting forward, and the bidet or hips are washed with the warm water.

As for the device for driving the cleaning nozzle device, as shown in FIG. 1, for example, a motor device is arranged below the nozzle portion as one drive source. Further, each nozzle part is integrally provided with a downward extension part, and is provided with a transmission part which is meshed with and attached to the downward extension part and which is driven by a motor device as a drive source. That is, more specifically, a circular gear (8) is provided as a member that is engaged with and disengaged from the downward extending portion formed of the linear gear (7), and the rotational power is generated by the rotation of the motor device (6) of the drive source. Is transmitted to the nozzle portion by the meshing of the gear portion (8a) of the circular gear (8) and the linear gear (7), and enables its forward and backward linear movement.

In the example of FIG. 1, the circular gear (8) is provided with the gear portion (8a) only in substantially half the circumference, and the gear portion is not provided in the other half circumference. Thus, for example, when the motor device is rotated clockwise from the state shown in FIG. 1, the circular gear (8) connected thereto is also rotated in the same direction. Then, the linear gear (7) integrally provided on the lower portion of the cylinder (4) on the side of the buttocks cleaning nozzle (2) meshes with the gear portion (8a) of the circular gear (8) to move the cylinder (4) forward. , The posterior washing nozzle (2) is projected forward to a required washing position.

On the other hand, on the side of the bidet cleaning nozzle (1),
There is no meshing between the linear gear (7) below the cylinder (3) and the gear portion (8a) of the circular gear (8). Therefore, the nozzle part of the bidet cleaning nozzle (1) does not move at all,
It will not move forward or backward. After the washing of the buttocks, the motor device is rotated counterclockwise, and the nozzle portion for washing the buttocks moves backward due to the engagement between the linear gear (7) and the gear portion (8a) of the circular gear (8). , Return to the initial position. Even at this time, the bidet cleaning nozzle (1) does not move at all.

It is not necessary to say that the bidet cleaning can be performed by rotating the motor device in the opposite direction. In the device of FIG. 1, the circular gear (8) is
Although it is directly connected to the motor device (6), it goes without saying that a further gear mechanism, a belt pulley transmission mechanism or the like may be interposed. Further, without being limited to the relationship between the circular gear (8) and the linear gear (7), an interlocking mechanism for transmitting the driving force can be appropriately adopted.

When a power failure or failure occurs in a state where the nozzle is projected forward, the nozzle may be manually returned to the initial retracted position, or the nozzle may be manually pulled out for cleaning. it can. In any case, as described above, according to the present invention, the cleaning device is provided with the plurality of nozzle portions having the bidet cleaning nozzle (1) and the buttocks cleaning nozzle (2) arranged in close proximity to each other. Even if there are such nozzles, these nozzles are normally arranged so as to descend forward, so that the space below the nozzles that accompanies this inclination is effectively used as the arrangement of the drive source.

For this reason, unlike the prior art, since the drive source is not placed on the same plane as the nozzle portion, the degree of freedom in assembly and arrangement is increased, and the design of the drive device having good operability and position adjustment performance,
Assembly is much easier than before. Further, in the present invention, since the nozzle portion can be driven independently, only the used nozzle portion is slid forward from the standby initial position, and the unused nozzles are kept at the initial position. The position adjustments for moving and stopping the nozzle portions are independently performed with high precision for each nozzle portion.

Therefore, the convenience is improved, and the unused nozzle can be kept clean without being contaminated. The position accuracy is also good. 2 and 3 are a plan view and a cross-sectional view illustrating a part of a warm water washing toilet seat in which the above-described washing nozzle device and its driving device are incorporated in the toilet seat, for example. Also in this example, the bidet cleaning nozzle (1) and the posterior cleaning nozzle (2) are provided in the nozzle portion, and the plurality of nozzles can be independently moved forward and backward.

In the above example, the cylinder (3)
Although the slide movement of (4) is described as an example, the connection between the cylinders (3) and (4) and the bidet washing nozzle (1) and the buttocks washing nozzle (2) has various structures. Is possible. Needless to say, the piston-cylinder mechanism of the nozzle may be used to form a multi-stage telescopic nozzle portion or a nozzle portion formed by sliding movement of only the cylinders (3) and (4).

Of course, the present invention is not limited to the above examples, and various embodiments can be made in its details.

[0018]

As described in detail above, according to the present invention, it is possible to separately drive a plurality of cleaning nozzle portions, and further, the driving can be performed with a simple structure, and the position can be adjusted with high precision. An easy drive is provided.
