Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning nozzle and a cleaning device used for a sanitary cleaning toilet seat for cleaning a human body part and a control device suitable for the cleaning device.

[0002]

2. Description of the Related Art Conventionally, as a cleaning device of this kind for cleaning a human body, a cleaning nozzle having a single or a plurality of nozzle holes is used to spray hot water to intensively clean a local part.
Alternatively, as shown in FIG. 6 and FIG. 7, there is a device that can utilize a fluid oscillation element having a feedback channel to perform a relatively wide range of cleaning by a water spraying effect.

In the figure, 1 is a toilet bowl, 2 is a sanitary washing toilet seat, which is provided so as to project into the toilet seat 3, the toilet lid 4, a main body 5 containing a cleaning device, and the toilet bowl 1 for cleaning the local area of the human body 6. A cleaning nozzle 7 is provided. FIG. 6 shows the structure of the cleaning nozzle 7. Reference numeral 8 is a washing water supply passage, 9 is a jet outlet, 10 and 11 are attachment walls, and 12 and 13 are feedback water passages.

In the above structure, when the cleaning water is attached to the adhering wall 10 side of the cleaning nozzle 7 and jets out to the arrow A side, the cleaning water flows into the feedback channel 12 side and becomes the washing water jetted to the arrow A side. Pressure is applied from the side surface to move the running water to the adhering wall 11 side and eject it from the arrow B side. By repeating this state, the self-oscillation state occurs. As a result, the cleaning effect and the water spraying effect can be obtained even with a relatively small amount of water.

[0005]

In the conventional cleaning apparatus as described above, it is possible to intensively clean the human body local area or to clean the local area in a distributed manner, but use both of them according to preference. There was a problem that I could not do it.

That is, since this type of cleaning device has a plurality of users, the comfortable cleaning mode differs depending on sex, age, individual difference, physical condition, and the like. For this reason, the water pressure is generally variable, but the water pressure is adjusted in the same pattern, so that the desired comfortable cleaning form may not always be obtained. Particularly in the case of local washing of women, there is a difference in the form of washing required between normal washing and the purpose of maintaining hygiene during the period of menstruation, and improvement is desired.

The present invention is to solve the above problems,
The cleaning nozzles are provided with two flow paths each, and a main nozzle hole and a sub-nozzle hole are provided corresponding to each flow path to control the cleaning water ejected from the side nozzle holes to concentrate or disperse the human body part. It is a first object of the present invention to provide a cleaning nozzle capable of selectively switching the cleaning method according to preference.

A second object is that the washing of the anus and the washing of the female part are constituted by different nozzle bodies, and an optimum washing pattern corresponding to each is obtained, and intensive washing and dispersion are performed respectively. It is to provide a sanitary washing device that can be washed.

A third object of the present invention is to provide a control device suitable for this type of sanitary washing device, which is capable of performing intensive washing, dispersion washing selection, and automatic washing according to a predetermined mode.

In order to achieve the above first object, the sanitary washing nozzle of the present invention comprises a wash water supply means, a main flow path and a sub flow path communicating with the wash water supply means, and a main flow thereof. A nozzle body having a main nozzle hole communicating with the passage and a sub nozzle hole communicating with the sub flow passage, and a jet flow discharged from the main nozzle hole are in contact with the jet flow discharged from the sub nozzle hole. An on-off valve that controls the opening and closing of the sub-channel is provided.

In order to achieve the second object, the sanitary washing device of the present invention comprises a washing water supply means, a main flow path and a sub-flow path communicating with the cleaning water supply means, and a main flow path communicating with the main flow path. With a sub nozzle hole communicating with the nozzle hole and the sub flow path,
A first nozzle body for cleaning the user's anus and a second nozzle body for cleaning the female part, which is composed of the same members as the first nozzle body, and the first and second nozzles. A switching valve for selectively switching the body is provided, and an opening / closing valve for controlling the opening / closing of the sub flow paths of each of the first and second nozzle bodies is provided.

In order to achieve a third object, the control device of the present invention has a first nozzle body for cleaning the user's anus and a second nozzle body for cleaning the female part. Each of the nozzle bodies has a main flow path and a sub flow path, a main nozzle hole communicating with the main flow path, and a sub nozzle hole communicating with the sub flow path, and the sub flow of each of the first and second nozzle bodies. A sanitary washing device having an opening / closing valve for controlling the opening / closing of a passage, comprising: first control means having a first switch for selecting opening / closing of the opening / closing valve; and second switch having a second switch for intermittently driving the opening / closing valve. By closing the second control means and the third switch, the on-off valve is automatically closed for a predetermined time to discharge the wash water only from the main nozzle hole, and then the on-off valve is pulsed. Drive intermittently to discharge cleaning water from the sub nozzle hole, After that, the opening / closing valve is opened for a predetermined time to discharge the cleaning water from both the main and sub nozzle holes, and the operating time of the automatic cleaning circuit for automatically stopping the cleaning water supply means and the automatic cleaning circuit is set. The third control means has a timer circuit for setting.

[0013]

With the above-described structure, the cleaning nozzle of the present invention allows cleaning water to be discharged only from the main nozzle hole if the on-off valve is kept closed, and intensive cleaning is possible. Then, the cleaning water is discharged from both the main nozzle hole and the sub nozzle hole. Since the jet flow discharged from the sub nozzle hole is configured so as to contact and interfere with the jet flow from the main nozzle hole, the jet flow from the main nozzle hole receives the physical fluid force of the jet flow from the sub nozzle hole. As a result, the jet state changes, and the jet becomes more dispersed than a single jet. Further, the opening area of the nozzle is expanded by opening the sub nozzle hole for the cleaning water sent into the nozzle cylinder at a constant flow rate.
That is, the jet flow is divided into the main nozzle holes and the sub-nozzle holes and discharged, so that the jetting speed is also reduced, and the jet flow is dispersed and has a gentle sensation. If the on-off valve is opened and closed intermittently,
The concentrated and dispersed cleaning is performed intermittently, so that the cleaning effect is improved and the massage effect on the portion to be cleaned is also obtained.

Further, the washing apparatus of the present invention is provided with separate nozzles for washing the anus and washing the female part, which makes it possible to set a jet pattern suitable for each type of washing, and especially for washing the female part. Target. Since each nozzle body has a main nozzle hole and a sub nozzle hole,
It is possible to select concentrated or dispersed washing in each washing of the anus and the female part, and the degree of freedom in selecting the washing pattern can be expanded.

Further, in the control device of the present invention, the opening / closing valve is controlled by turning on the first switch, and the ejection of washing water from the sub nozzle hole is controlled. That is, concentrated or dispersed cleaning can be arbitrarily selected.

Further, when the second switch is turned on, the on-off valve is automatically opened and closed intermittently, and concentrated and dispersed cleaning are alternately repeated.

Further, when the third switch is turned on, the cleaning is automatically performed for a predetermined time from only the main nozzle hole by the concentrated jet flow, and then the opening / closing valve is intermittently opened / closed in a pulsed manner to alternately perform the concentrated and dispersed cleaning. Repeatedly thereafter, the on-off valve is opened and maintained, both main and sub nozzle holes are opened for a predetermined time to perform the distributed cleaning, and after a predetermined time, the cleaning is automatically stopped. That is, automatic cleaning can be realized.
