Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sanitary washing apparatus having a local washing function, and particularly to a structure of a nozzle for jetting washing water.

[Conventional technology]

A sanitary washing device having a local washing function generally has a structure in which warmed washing water is jetted toward a local portion by a nozzle device, and an example is shown in FIG.

In the figure, the casing of the sanitary washing device is
A toilet seat 21 and a toilet lid 22 are attached to the casing 20 so as to be freely opened and closed. Inside the casing 20,
A tank for heating the washing water, a hot air fan for drying, and a control unit are built in, and the operation of each function is performed by an operation unit 20 a provided on the upper surface of the casing 20. Then, the cleaning nozzle device 1 is incorporated so as to be able to protrude and retract from the casing 20, and is connected to a cleaning water supply system.

The nozzle device 1 includes a nozzle body 2 that moves between a storage position and a cleaning position by a driving device such as a motor or a supply pressure of cleaning water, and a nozzle head 3 provided at a tip end thereof. As shown in FIG. 6, the nozzle head 3 is provided with two types of ejection holes for use for anal cleaning and bidet use. One is a first vent hole 23 for anal irrigation, and the other is a second vent hole 24 for bidet. These jet holes 23 and 24 are respectively connected to a first flow path 2a and a second flow path 2b formed inside the nozzle main body 2 and supplied with cleaning water separately. Then, the second ejection hole 24 is located on the tip side, and when used as a bidet, the stroke of the nozzle body 2 is set to the cleaning position where the stroke is lengthened.

[Problems to be solved by the invention]

When the nozzle body 2 reaches the washing position, the tip is inclined downward, and the first and second ejection holes 23 and 24 are also optimally designed so that they can be used for anal washing and bidet use. ing. That is, as shown in FIG.
The number of the ejection holes 23 is, for example, 3 and the inside diameter thereof is also small so that the washing water can be spouted vigorously. We make it possible to blow out soft cleaning water. The rising angle of the second ejection hole 24 with respect to the axis of the nozzle body 2 is larger than the opening axis of the first ejection hole 23.

However, when the nozzle head 3 is integrally formed of synthetic resin or the like, the inclination of the opening axis of the first ejection hole 23 and the second ejection hole 24 is different.
The structure of the mold becomes considerably complicated and the molding itself is very difficult. In addition, even when one of the ejection holes is made into a mold and the other is formed and then machined, machining to properly have or finely adjust the opening axis becomes complicated.

As described above, in a structure in which the nozzle head 3 is formed as a single body and has two types of ejection holes, it is difficult to process the ejection holes. In particular, in the case of using a mold, since the change after the specification is determined is expensive, it is not possible to make a fine adjustment such that the specification is changed and the inclination of the opening axis is optimal.

The problem to be solved by the present invention is to facilitate the processing of the ejection hole of the nozzle head and to realize the required ejection direction of the washing water with high accuracy.

[Means for solving the problem]

According to the present invention, a plurality of washing water channels are provided in one nozzle body, and a group of ejection holes connected to these channels are provided in a tip nozzle head, and the nozzle body is moved from a storage position to a washing position. In the sanitary washing device provided so as to be able to advance and retreat, a group of ejection holes communicating with one flow path is opened in the nozzle head, and each of the ejection paths of this group communicates with the remaining flow paths at a different position from the ejection holes. Attaching portions were opened at the positions, and these attaching portions were formed in a cross-sectional shape depressed from the surface of the nozzle head, and ejection holes were opened in a member separate from the nozzle head and buried and fitted in the attaching portion. It is characterized by the following.

In addition, a plurality of ejection holes that can be opened in a member separate from the nozzle head can be provided, and when the nozzle body is in its storage position, the entire nozzle head including the member buried and fitted in the mounting portion is provided. May be provided.

[Action]

In a sanitary washing device, it is usual to use the anal wash and the bidet properly. For this reason, the nozzle body may be provided with two channels and the nozzle holes of the nozzle head may be arranged in two places.

Therefore, by providing one group of ejection holes in the nozzle head itself and providing the other ejection hole in another member and incorporating it in the mounting portion of the nozzle head, it is possible to form a nozzle head with respect to one ejection hole when making a mold. It is only necessary to consider the direction in which the mold is removed, and the degree of freedom in design is improved.

〔Example〕

FIG. 1 is a longitudinal sectional view showing a main part of the nozzle device of the sanitary washing device of the present invention.

As described in FIG. 5, the first flow path 2a and the second flow path
2b are formed separately, and the nozzle head 3 is integrated with the tip.

As shown in FIG. 2, the nozzle head 3 has a partition inside.
3a is formed to form a first chamber 3b and a second chamber 3c communicating with the first and second flow paths 2a and 2b, respectively. Then, in the upper surface of the first chamber 3b, a first ejection hole 4 used for anal cleaning is opened, and
On the upper surface of the chamber 3c, there is provided a mounting opening 3d of a plate 5a having a second ejection hole 5 shown in FIG. A throttle 2c is provided at the end of the second flow path 2b (FIG. 1), and an air hole 3e is opened in the peripheral wall of the second chamber 3c immediately downstream of the throttle 2c. With this configuration, the speed of the washing water from the second flow path 2b is increased by the throttle 2c, and when the washing water enters the second chamber 3c, the internal pressure is reduced, so that air is sucked from the air holes 3e. Therefore, air is mixed into the washing water to form a foam, and the foam water is jetted from the second ejection hole 5 of the plate 5a.

The plate 5a has a flat plate shape as shown in FIG. 3, and is integrated with the mounting opening 3d of the nozzle head 3 by an adhesive or welding. The number of the second ejection holes 5 is larger than that of the conventional example in order to inject the foam water, and when the second ejection holes 5 are fixed to the mounting port 3d, the opening axis of the second ejection holes 5 is the same as that of the conventional example. The rising of one ejection hole 4 is larger than that of one ejection hole 4.

FIG. 4 is a side view showing an attachment structure of the nozzle device 1 to the casing 20.

As shown, a base 10 of the nozzle device is fixed inside the casing 20, and the nozzle main body 2 is incorporated in the base 10 so as to be movable in the axial direction. Base 10
Is a concave curved slide surface for receiving the lower surface of the nozzle body 2
A cleaning chamber for washing the nozzle head 3 is provided at the tip. A drive motor 11 is fixed to the base end side of the base 10, and the nozzle body 2 is mechanically connected to an output shaft of the base 10 by using an appropriate means. Joints 12a and 12b communicating with the first and second flow paths 2a and 2b, respectively, are connected to the nozzle body 2, and these joints 12a and 12b are connected to a hot water tank (not shown) built in the casing 20. Are connected.

In the above configuration, when the anal cleaning switch of the operation panel 20a is turned on, the nozzle body 2 is extended by the drive motor 11, and reaches the cleaning position A in FIG. Then, the washing water supplied from the first flow path 2a is ejected from the first ejection hole 4 in the direction of the arrow in FIG. When the bidet switch is turned on, the nozzle body 2 extends until the nozzle head 3 reaches the position B, and the washing water from the second flow path 2b becomes foamed water and flows from the second ejection hole 5 in the direction of the arrow. It is injected. In this manner, the nozzle head 3 can be changed in position and used for anal cleaning and bite use, and the angle of water discharge from the first orifice 4 and the second orifice 5 can be set to a posture corresponding to these.

Here, since the second ejection holes 5 are formed on the plate 5 a separate from the nozzle head 3, the orientation of the second ejection holes 5 can be set regardless of the inclination of the opening axis of the first ejection holes 4. . That is, the posture of the first ejection hole 4 can be processed with high precision when the nozzle head 3 is molded, and the second ejection hole 5 is opened when a separate plate 5a is manufactured.
The difficulty in manufacturing the nozzle head 3 in a mold is reduced.
Therefore, the mold for manufacturing the nozzle head 3 is simplified, and the degree of freedom in design is improved. The same applies to the case of the second ejection holes 5, so that the machining accuracy of these ejection holes 4, 5 can be improved, and the relationship between the two inclination angles can be set appropriately.

[Effect of effect]

In the present invention, for example, one of the two types of ejection holes provided in the nozzle head at the tip of the nozzle body is provided in the nozzle head, and the other is opened in another member, and this is integrated with the nozzle head. For this reason, for the two types of ejection holes having different opening axis directions, only one of the ejection holes needs to be machined in the nozzle body, so that in the case of mold production, the mold becomes simpler and the machining becomes easier. In addition, the other ejection hole provided in a member different from the nozzle head can be similarly easily manufactured. Therefore, the processing accuracy of the two types of ejection holes is also increased, and a nozzle device in which the required jetting direction of the washing water is appropriate can be obtained, and comfortable washing can be performed. Further, if a mold is formed in which another member is formed into a plate shape and the ejection hole is formed, the mold can be easily changed, and the specification can be easily changed, and the inclination of the ejection hole can be finely adjusted.
