Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a nozzle for a cleaning device that is attached to a toilet bowl and sprays water onto private parts of the human body such as the anus.

[Background of the Invention 1 Conventionally, this type of nozzle for a cleaning device has a structure that only sprays water in a fixed direction, so the water does not necessarily hit the appropriate place, and the user has to adjust the seat position on the toilet bowl. Since the fountain must be adjusted to be shifted as appropriate, and because the water is concentrated in a certain position on a sensitive private part, there are inconveniences such as making the user feel pain.

[Objective of the Invention 1] This invention addresses these problems and provides a nozzle body connected to a water inlet for introducing cleaning water, a passage plate joined to the nozzle body, and an outer plate joined to the passage plate. A flow path is formed in a predetermined pattern between the nozzle main body, the outer plate, and the flow path plate marked mj, and the toilet bowl has a water fountain that tapers out in the front-rear direction of the toilet bowl and allows flushing water to flow through the toilet bowl. A fluid element is configured to oscillate and move so that it adheres alternately to the front and rear tapered walls of the water fountain, and by swinging the water from the nozzle back and forth, a high cleaning effect and a comfortable feeling of use can be obtained. The objective is to provide a device that can minimize the accompanying increase in size and complexity of the nozzle.

[Example 1 Examples thereof will be described below based on the drawings.

FIG. 1 is a schematic explanatory diagram of a cleaning device according to the present invention. 1
2 is a toilet bowl, 2 is a cleaning device main body, and 3 is a cleaning nozzle which is the object of the present invention. The cleaning nozzle 3 integrally has a sill 4, and is extended from the cleaning device main body 2 to a predetermined cleaning position in the toilet bowl 1 via the sill 4 during water fountaining.

2 to 6 all show the configuration of each part of the nozzle 3. FIG. The nozzle 3 is formed by abutting a nozzle body 3' and an id body 3 formed by joining a channel plate 13 and an outer plate 14, and the nozzle body 3' is formed by abutting on an id body 3' formed by joining a channel plate 13 and an outer plate 14. tS3 diagram (A)
A flow path a with a pattern as shown in Fig. 3 is carved in the guide body 3'', and a flow path with a pattern shown in Fig. f53 (B) is carved in the guide body 3''. , / respectively represent the joining surfaces of the nozzle body 3' and the side body 3', and therefore the flow path a connects the nozzle body 3' and the flow path plate 13.
A flow path is formed inside the id body 3, that is, between the flow path 13 and the outer plate 14.

The flow path a communicates with a water guide 1''5 (see FIG. 4) that introduces the wash water that is force-fed into the nozzle body into the nozzle body, and is connected to a water guide that guides the wash water from the water inlet 5. Introductory path 6
and a nozzle part 7 that spouts water from the water introduction passage 6, with the spout of the nozzle part 7 facing the base thereof, and expanding upward in a tapered shape in the left and right direction, that is, in the front and back force direction with respect to the toilet bowl 1. a fountain [18], a pair of front and rear control channels 9 and 9° that open one end at the base of the fountain 8, and a space 10 in which the other ends of the control channels 9 and 9° are opened, respectively.・1
It consists of 0゛.

One flow path has an opening 12' along the tapered wall 81 on the front side of the fountain 8, and a signal path 11 communicating with the air opening 10 indicated at 41f, and a tapered wall 8 on the rear side of the fountain [18]. −
The signal path 11' has an opening 12 at a position along the space 10' and a signal path 11' that communicates with the space 10'. The openings 12 and 12' are both bored in the channel plate 13, and f: pJ5.
As shown in the cross section of FIG. 6, grooves 15 and 15' are formed in the openings 12 and 12' so as to face the fountain 8 and extend downward. Therefore, part of the water spouted from the fountain 8 is
Guided by the grooves 15 and 15', it flows into the signal paths 11 and 11' through the openings 12 and 12', and is brought to the air II ports 0 and 10', respectively. In this way, a reflux path is formed that communicates with the base of the rear tapered wall 8-2 through the signal path 11, the space 10, and the control waterway 9 through the opening 12° near the front tapered wall 8-1; A return flow path is formed from the opening 12 near the rear tapered wall 8-2 to the base of the front tapered wall 8-1 via the signal path 11', the space 10'', and the control waterway 9'' so as to form a pair with the rear tapered wall 8-2. be done.

In the embodiment configured in this manner, when cleaning water is introduced into the cylinder 4, the cleaning water passes through the water inlet 5 and the water introduction path 6 and is sprayed from the nozzle portion 7. At the beginning of the sprayed cleaning water, the direction of the water flow is extremely unstable.
It adheres to either the front or rear tapered wall of the water fountain 8 and becomes temporarily stable.

Now, suppose that the fountain has adhered to the rear tapered wall 8-2 as shown in FIG. 3(A). The spaces 10 and 10' store water that has entered from the openings 12 and 12' through the signal paths 11 and 11', and this water is ejected from the fountain 8 and expands to take in the surrounding fluid. It is drawn into the flowing water flow and taken into the adhering water flow from the control channel 9.9゛.
It is released along with the attached water. This Il? , the control waterway 9.
Due to the pipe resistance, water cannot be supplied sufficiently to eliminate this problem, and the base of the fountain [18] was previously maintained at negative pressure, and the flow becomes stable.

A part of the adhering water is introduced into the space 10' through the opening 12, and water continues to be sent out from the control channel 9';
Atmospheric air is introduced into the interior of the control channel 9 through the opening 12', and the water inside gradually decreases until the air is introduced into the adhering water flow through the control channel 9. Control channel 9 on the adhering side according to adhering water
When more air is introduced, air, which has a much lower viscosity than water, flows in enough to eliminate the negative pressure at the base of the adhering flow, and therefore the adhesion to the tapered wall 8-2 is broken. On the other hand, since water is continuously taken in from the control waterway 9' and maintained at negative pressure, this separated water flow moves to and adheres to the tapered wall 8-1 on the opposite side.

When the adhesion moves to the front taper 18-1 in this way,
This time, some of the adhered water enters the space 10 through which the atmosphere had been introduced through the opening 12'', while the water that had been stored in the space 10'' is just taken into the adhered water through the control channel 9''. As a result, air is introduced into the adhered water through the control waterway 9.

When the atmosphere is introduced through the control waterway 9', the adhering water is peeled off from the tapered wall 8-1 in the same manner as described above, moves to and adheres to the rear tapered wall 8-2 again.

In this way, the 7-zuru 3 fountain performs an oscillating movement in which it adheres alternately to the front and rear tapered walls, swinging back and forth. This oscillation is made periodically by introducing air from the control channel on the side where the fountain is attached, and this period is
It can be changed depending on the size of the capacitance of 0.10'. That is, the larger the capacity of the space 10.10', the longer the period, and the smaller the capacity, the shorter the period. In addition, in actual use, 1
A shorter period of less than a second provides a softer usability and allows for a more compact structure.

[Effects of the Invention 1 This invention is configured as described above, and has the following remarkable effects.

The toilet bowl has a water fountain that expands in a tapered shape in the front and back direction, and the water from the nozzle is oscillated and moved so that it alternately adheres to the tapered walls at the front and back of the fountain, so the water from the nozzle is swung back and forth for cleaning. It has a wide range, and even if the user's sitting position on the toilet bowl varies slightly depending on the person, the user's private parts can be reliably washed.

Is the fountain i? Since it swings after iI and hits the part to be cleaned intermittently, it is possible to promote the removal of dirt from the private part and improve the cleaning effect.

Unlike conventional devices, the fountain is not concentrated in one point, so the user can use it comfortably without feeling any pain, and the oscillating flow can be expected to produce a pine surge effect.

The oscillation of the fountain is brought about by forming a fluid element, 8! Since no special mechanical configuration is required, the configuration is simple and can be manufactured inexpensively and compactly, and moreover, it can be used semi-permanently without failure.

The nozzle body is connected to a water inlet for introducing cleaning water, a flow path plate is connected to the nozzle body, and an outer plate is connected to the flow path plate. Since a fluid element is constructed by forming a flow path in a predetermined pattern between the parts, it is possible to create a flow path by setting grooves in the necessary pattern on the joint surfaces of the nozzle body, flow path plate, or outer plate, and joining each part. The structure is simple and compact.
