DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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] 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 seating position on the toilet appropriately. The user has to adjust the position to shift the water, and the water is concentrated in a certain position on a sensitive private area, which causes pain to the user.

[Object of the Invention] The present 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. forming a flow path in a predetermined pattern between the nozzle body and outer plate and the flow path plate,
A fluid element is configured to have a water spout that expands in a tapered manner in the front and back direction of the toilet bowl, and oscillates and moves cleaning water so that it adheres alternately to the tapered walls at the front and rear of the water spout, and the water fountain from the nozzle is directed back and forth. The purpose of the present invention is to provide a device that provides a high cleaning effect and a comfortable feeling of use through rocking, and also minimizes the size and complexity of the nozzle associated with this.

[Example] 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 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 is
It has a cylinder 4 integrally, and is extended from the washing device main body 2 through the cylinder 4 to a predetermined washing position in the toilet bowl 1 when a water fountain is used.

2 to 6 each show the configuration of each part of the nozzle 3. FIG. The nozzle 3 includes a nozzle body 3',
It is formed by abutting a guide plate 3'' formed by joining a channel plate 13 and an outer plate 14, and the nozzle body 3' has a channel a having a pattern as shown in FIG. 3A.
However, each of the guide bodies 3'' is carved with a flow path b in the pattern shown in FIG. 3B. In addition, FIGS. Therefore, the flow path a is formed between the nozzle body 3' and the flow path plate 13, and the flow path b is formed between the inside of the guide body 3'', that is, the flow path plate 13 and the outer plate. 14.

The flow path a is a water introduction path that communicates with a water inlet 5 (see FIG. 4) that introduces the wash water that is force-fed into the cylinder 4 into the nozzle body, and guides the wash water from the water inlet 5. 6, a nozzle part 7 for spouting water from the water introduction passage 6, and a nozzle part 7 at the base thereof.
a water fountain 8 that tapers upward to the left and right, that is, the front and back directions of the toilet bowl 1 with the spout thereof facing upward; and a pair of front and rear control channels 9, 9 that open one end at the base of the fountain 8. ', and a space 1 in which the other ends of the control waterways 9 and 9' are respectively opened.
0,10'.

One flow path b has an opening 12' along the tapered wall 8-1 on the front side of the water fountain 8, and a signal path 11 communicating with the space 10, and a tapered wall 8 on the rear side of the water fountain 8. -2, and a signal path 11' having an opening 12 and communicating with a space 10'. Both of the openings 12 and 12' are connected to the channel plate 13.
As shown in cross section in FIGS. 5 and 6, grooves 15 and 15' are formed in the openings 12 and 12' so as to face the water fountain 8 and extend downward.
Therefore, part of the water spouted from the water fountain 8 is guided by the grooves 15, 15', flows into the signal paths 11, 11' through the openings 12, 12', and is brought to the spaces 10, 10', respectively. It turns out. In this way, a return flow path is formed which communicates from the opening 12' near the front tapered wall 8-1 to the base of the rear tapered wall 8-2 via the signal path 11, the space 10, and the control waterway 9; The signal path 11' is connected from the opening 12 near the rear tapered wall 8-2 to form a pair with the
A return flow path is formed that reaches the base of the front tapered wall 8-1 via the space 10' and the control waterway 9'.

In the embodiment configured as described above, when the cleaning water is introduced into the cylinder 4, the cleaning water is injected from the nozzle portion 7 through the water introduction port 5 and the water introduction path 6. The direction of the jetted cleaning water is extremely unstable at the beginning of the fountain, and it becomes temporarily stable when it adheres to the tapered wall either at the front or rear of the water fountain 8.
Suppose now that the fountain has adhered to the rear tapered wall 8-2 as shown in FIG. 3A. space 10,10'
The water that enters through the signal paths 11 and 11' from the openings 12 and 12' is stored, and this water is ejected from the water fountain 8 and expands to form a flowing water flow that takes in the surrounding fluid. drawn by the control waterway 9,
It is taken into the adhering water flow from 9' and released together with the adhering water. At this time, the control channels 9 and 9' are unable to supply enough water to eliminate the negative pressure caused by the adhering water flow trying to take in the surrounding fluid due to their resistance, and the base of the fountain 8 has previously been under negative pressure. The pressure is maintained and the attached 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', but air is introduced into the other space 10 through the opening 12', and the water inside is It gradually decreases until finally the air is introduced into the adhering water flow through the control waterway 9. When air is introduced into the adhesion water from the control channel 9 on the adhesion side, the air, which has a much lower viscosity than water, flows in in an amount sufficient to eliminate the negative pressure at the base of the adhesion flow. 2
The adhesion to is released. On the other hand, since water is continuously taken in from the control channel 9' and maintained at a 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 tapered wall 8-1, the opening 1 enters the space 10 where the atmosphere was introduced.
A part of the adhering water enters from space 2', and on the other hand, from space 1
The water stored in 0' is gradually reduced as it is taken into the adhered water through the control waterway 9', and air is introduced into the adhered water through the control waterway 9'.
When the atmosphere is introduced through the control waterway 9', the adhered 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 water fountain from the nozzle 3 performs an oscillating movement in which it adheres alternately to the front and rear tapered walls, swinging back and forth. This oscillation is periodically performed by introducing atmospheric air from the control channel on the side to which the fountain is attached, and this period can be changed depending on the capacity of the spaces 10, 10'. That is,
The larger the capacity of the spaces 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 configuration.

[Effects of the Invention] The present 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. The range is wide, and the user's private parts can be reliably cleaned even if the seated position of the user on the toilet varies slightly depending on the person.

Since the fountain swings back and forth and hits the area to be cleaned intermittently, it is possible to promote the removal of dirt from the private parts 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 achieved by forming a fluid element and does not require any special mechanical construction, so it can be manufactured easily, inexpensively, and compactly, and is semi-permanent without failure. It becomes possible to use it.

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. A fluid element is constructed by forming a flow path in a predetermined pattern between the nozzle body,
A predetermined flow path is formed by providing grooves in the necessary pattern on the joint surface of the flow path plate or outer plate and joining each part, and the structure can be simple and compact.
