Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to an ejection nozzle device used for a human body local cleaning device for cleaning local parts such as anus and bidet of a human body.

(Prior Art) In recent years, human body local cleaning equipment has been recognized for its usefulness from the viewpoint of health and hygiene, and has been widely used. In this human body local cleaning device, a jet nozzle device that jets cleaning water to a local part of a human body is used. In the ejection nozzle device, the ejection nozzle is disposed at the base so as to be movable from the nozzle storage position of the base to the cleaning use position, and the nozzle cleaning unit is disposed near the ejection nozzle.

In this ejection nozzle device, at the time of use, the ejection nozzle is moved from the nozzle storage position at the base, and the washing water is ejected from the ejection hole of the ejection nozzle to a local part of the human body to wash the local part of the human body. Here, during use, there is a possibility that filth such as stool adheres to the ejection hole portion of the ejection nozzle, which is dried and solidified, and that the ejection hole is clogged. Therefore, after cleaning the local part of the human body, the cleaning water is discharged from the nozzle cleaning portion to the ejection hole portion of the ejection nozzle to wash the ejection hole portion, thereby improving the problem of contamination of the ejection hole and clogging of the ejection hole.

(Problems to be Solved by the Invention) By the way, in the above-described conventional human body local cleaning device, the washing water adheres to the ejection hole portion of the ejection nozzle because the ejection hole portion of the ejection nozzle is washed with the washing water. Most of the washing water is tap water, rarely well water is used.
Components contained in the washing water attached to the ejection hole portion of the ejection nozzle (these are generally called scales), such as calcium components, are solidified by drying the washing water. Then, the ejection hole may be contaminated with the solidified component, or the ejection hole may be clogged.

The present invention has been made in view of the above-mentioned problems, and is directed to a human body local cleaning device that is advantageous in improving the problem that the ejection holes are stained with the solidified component of the washing water and the problem that the ejection holes are clogged. An object of the present invention is to provide a jet nozzle device.

[Structure of the Invention] (Means for Solving the Problems) A jet nozzle device for a human body local cleaning device according to the present invention is provided with a base and a base which is movably held from a nozzle storage position of the base to a cleaning use position, An ejection nozzle having an ejection hole for ejecting washing water for washing a local part of a human body, a nozzle washing unit provided at a base for ejecting washing water for washing at least an ejection hole portion of the ejection nozzle, and housed in a nozzle storage position of the base. A cover member that covers at least the ejection hole portion of the ejection nozzle in a state where the ejection nozzle has been set, wherein the cover member covers the ejection hole portion of the ejection nozzle accommodated in the nozzle accommodation position and ejects the same. It has a water supply member that keeps the hole portion in a wet state.

The base has a nozzle storage position and holds the ejection nozzle protrudably from the nozzle storage position. The base is
For example, a tank having a water storage chamber for supplying cleaning water to the ejection nozzle, a cylinder disposed in a hot water tank or the like for housing the ejection nozzle, a cover for covering the tank, or a human body local washing to which the nozzle device is attached The device itself can be used, but is not necessarily limited to these, and any device having a function of holding the ejection nozzle in a protrudable manner is sufficient.

The ejection nozzle only needs to have a function of ejecting washing water for washing a local part of the human body from the ejection hole, and a known nozzle can be employed. The ejection nozzle can be, for example, a type that can freely advance and retreat and protrudes from the nozzle storage position of the base by advancing, or a type that swings and protrudes from the nozzle storage position of the base. The number of jet nozzles may be one or two. The drive of the ejection nozzle can be variously selected as needed, such as a type in which the ejection pipe is pressed and projected using water pressure, an electric type in which the ejection pipe is projected by a motor, and a manual type.

The nozzle cleaning unit only needs to have a function of supplying at least the cleaning water for cleaning the ejection hole portion of the ejection nozzle to the ejection hole portion, and a known one can be employed. Note that the washing water ejected from the ejection nozzle and the washing water discharged from the nozzle washing section are usually supplied from the same water source, and generally tap water is used.

The cover member can be disposed on at least one of the base, the ejection nozzle, and the nozzle cleaning unit.

The cover member can be formed of a wall that covers the ejection nozzle by forming a minute gap as a relatively minute space from the outer surface side. The wall body may have a cylindrical shape covering around the ejection hole portion of the ejection nozzle, or a semi-cylindrical shape covering the upper half including the ejection hole portion of the ejection nozzle. The cover member is provided with a water supply member. The form of the water supply member can be as follows. For example, a flocking portion may be provided, and the washing water film may be held in a minute space between the hairs of the flocking portion. Further, as a water supply member, a concave portion having a minute depth, a porous portion such as a sponge,
Alternatively, a mesh portion having a mesh, a cloth having a stitch, or the like may be provided. In this case, a film of the washing water is held in the concave portion, the porous portion or the mesh portion, and the minute space of the cloth. The mesh portion can be formed of a soft resin or the like so as not to hinder the ejection operation of the ejection nozzle.

(Operation) In the ejection nozzle device according to the present invention, at the time of use, the ejection nozzle is moved from the nozzle storage position at the base to the use position, and in that state, the washing water is ejected from the ejection hole of the ejection nozzle to a local part of the human body. To clean the local area. Then, after the local cleaning, the cleaning water is discharged from the nozzle cleaning section to the ejection hole portion of the ejection nozzle to wash the ejection hole portion, thereby preventing contamination of the ejection hole and clogging of the ejection hole by waste such as stool. After use, the ejection nozzle is released from the protruding state, returned to the nozzle storage position at the base, and stored therein.

In the ejection nozzle device according to the present invention, when the ejection nozzle is stored in the nozzle storage position at the base, the cleaning water is held by the water supply member. Since the washing water is held by the water supply member in this manner, the ejection hole portion of the ejection nozzle becomes difficult to dry, and the components of the washing water hardly solidify.

[Embodiment] An embodiment of a jet nozzle device for a human body local cleaning device according to the present invention will be described with reference to FIGS. 1 and 2. FIG.

As shown in FIG. 2, a toilet seat 2 and a toilet lid 3 are provided on an upper portion of a toilet 1 as a human body local cleaning device. Above the toilet 1, a hot water tank 4 is provided. An electric heater (not shown) is provided in the water storage chamber of the hot water tank 4. The electric heater heats the water as the cleaning water stored in the water storage chamber of the hot water tank 4 to become hot water. Water as wash water is supplied from a water pipe 5 and a water supply valve 6 to the water storage chamber of the hot water tank 4 and the toilet 1.

Adjacent to the hot water tank 4, a hot air fan 7 for supplying hot air for drying the human body after cleaning and an operation unit 8 are provided. Hot water tank 4, hot air fan 7, operation unit 8
Are covered by a base cover 9.

As shown in FIG. 1, a cylinder 10 as a base is fixed to a side wall of the hot water tank 4. The inside of the cylinder 10 is a nozzle storage position. A jet nozzle 11 is mounted in the cylinder 10 so as to be freely protruded. An ejection hole 12 for ejecting cleaning water is formed above the tip of the ejection nozzle 11. Water pressure is applied to the tip wall 11a of the ejection nozzle 11 by a pump (not shown), and the ejection pressure causes the ejection nozzle 11 to protrude from the cylinder 10. Further, the ejection nozzle 11 is formed by a spring 13 provided in the cylinder 10,
It is retracted and urged in the direction in which it is stored in the nozzle 10 at the nozzle storage position.

Above the ejection nozzle 11, a nozzle cleaning pipe 16 as a nozzle cleaning unit is provided. Although not shown, the nozzle cleaning pipe 16 is connected to the hot water tank 4 side, and the hot water in the hot water tank 4 is supplied. The nozzle cleaning pipe 16 is formed with a water supply opening 17 that faces the ejecting nozzle 11 projecting from above from above.

By the way, in this embodiment, a cylindrical body 19 as a cover member is integrally formed at the tip of the cylinder 10. Tube 19
Covers the entire periphery around the ejection hole 12 of the ejection nozzle 11 from outside. Therefore, the inner surface of the cylinder 19 and the ejection nozzle 11
A minute gap 20 as a minute space is formed between the outer surface and the outer surface. As shown in FIG. 1, when the ejection nozzle 11 is accommodated in the nozzle accommodation position of the cylinder 10, the average thickness of the minute gap 20 near the ejection hole 12 is about 0.1 to 1.0 mm. The ejection nozzle 11 is held by a flange 10a on the distal end side of the cylinder 10 and a holding part (not shown) of the cylinder 10. Therefore, the thickness of the minute gap 20 is substantially uniform over the entire length of the portion where the ejection nozzle 11 protrudes from the cylinder 10. The material forming the cylindrical body 19 is a resin. Note that a receiving tray 22 is disposed below the jet nozzle 11 in the hot water tank 4.
The tray 22 allows the received washing water to flow down into the toilet 1.

Next, the operation of the ejection nozzle device according to the present embodiment will be described. First, at the time of local cleaning, the pump is driven and the tip wall 11a of the ejection nozzle 11 receives water pressure.
Moves forward in the direction protruding from the cylinder 10 and reaches the local cleaning position. The state of the protrusion and reaching the local cleaning position is shown by the two-dot chain line in FIG. Then, when the ejection nozzle 11 stops at the local washing position, water is ejected from the ejection hole 12, and the local washing is performed.

When the local cleaning is completed, the water pressure applied to the tip wall 11a of the ejection nozzle 11 disappears or decreases due to the stoppage of the pump, etc., so that the ejection nozzle 11 moves in the retreating direction by the urging force of the spring 13, and the ejection nozzle 11 Most are stored in the nozzle storage position of the cylinder 10 as shown by the solid line in FIG. At the same time, the hot water channel in the hot water tank 4 is switched to “nozzle cleaning”. Then, the cleaning water is discharged from the opening 17 of the nozzle cleaning pipe 16. The discharged washing water is applied to the outer surface of the retreating jet nozzle 11, particularly the jet hole portion 12.
Collide with In this case, the discharged water collides with the ejection nozzle 11 at a substantially right angle, and the collision force effectively cleans the ejection hole 12.

By the way, in the nozzle device according to the present embodiment, as described above, when the cleaning of the local part of the human body is completed, the ejection nozzle
11 moves in the retreating direction by the urging force of the spring 13 with the washing water adhered to its outer wall surface. At this time, the jet nozzle
The water adhering to the outer wall surface of 11 is held in the minute gap 20 by the surface tension, the film of the washing water is held in the minute gap 20, and the water is supplied to the water supply member W provided on the inner surface of the cylindrical body 19. Water is retained. Therefore, since the ejection hole 12 is covered with the water supply member W holding the cleaning water, the wet state can be maintained for a long time. Therefore, the ejection hole 12 of the ejection nozzle 11 is hard to dry for a long time, and the component of the washing water is hard to solidify. Therefore, in the nozzle device according to the present embodiment, it is possible to improve the problem that the ejection hole 12 is contaminated with the solidified component of the cleaning water and the problem that the ejection hole 12 is clogged.

Further, in the nozzle device according to the present embodiment, the ejection nozzle 11
Is directly in contact with the outside air only when the ejection nozzle 11 protrudes from the cylinder 10 when cleaning a local part of the human body,
Since it is always covered with the cylinder 19 via the cleaning water film,
Intrusion of outside dust and other foreign matter into the ejection hole 12 of the ejection nozzle 11 can be suppressed as much as possible, which is advantageous for suppressing clogging of the ejection hole 12. In addition, since the ejection nozzle 11 is normally covered with the cylindrical body 19 via the cleaning water film, the ejection nozzle 11 is deteriorated due to ozone in the outside air, the ejection nozzle 11 is deformed, and the ejection nozzle 11 is discolored. Can be suppressed as much as possible, which is advantageous for extending the life of the ejection nozzle 11.

Further, in the nozzle device according to the present embodiment, the ejection nozzle 11
Is always covered with the cylindrical body 19 that forms a film of washing water.In other words, when using urine, the jet nozzle 11 is covered with the cylindrical body 19, so that urine directly hits the jet nozzle 11. Can be prevented. Further, since the ejection nozzle 11 is normally covered with the cylindrical body 19 that forms a film of washing water, when cleaning the interior of the toilet 1 with a cleaning brush or the like, the cleaning brush may be accidentally applied to the ejection nozzle 11. The problem of deforming or breaking the ejection nozzle 11 can be reduced as much as possible. Therefore, it is advantageous for prolonging the life of the ejection nozzle 11.

(Other Embodiments) Another embodiment of the nozzle device according to the present invention is shown in FIGS. 3, 4, and 5. FIG. In the example shown in FIG. 3, the configuration is basically substantially the same as that of the above-described embodiment, and substantially the same functions and effects are exhibited. However, of the inner surface of the cylindrical body 19, the ejection nozzle
A flocking portion 24 as a water supply member is provided at a portion facing the ejection hole 12 when the nozzle 11 is stored in the nozzle storing position in the cylinder 10.
Is arranged. In this case, when the ejection nozzle 11 retreats with water attached to the outer surface thereof, the washing water attached to the outer surface moves to the minute space between the hairs of the flocking portion 24 and the flocking portion. Since the film of the washing water is held in the minute space between the hairs 24, the wet state of the ejection holes 12 can be reliably maintained. Further, when the ejection nozzle 11 retreats, the flocked portion 24 comes into contact with the portion of the ejection hole 12, so that the portion of the ejection hole 12 can be cleaned by the flocked portion 24, which is advantageous in suppressing clogging of the ejection hole 12. Note that a porous portion such as a sponge may be disposed instead of the flocking portion 24.

In the example shown in FIG. 4, the configuration is basically substantially the same as that of the above-described embodiment, and substantially the same operation and effect are exhibited. However, in the example shown in FIG.
The opening is formed between the front end wall 10b and the outer surface of the ejection nozzle 11. The arrow A in FIG.
The jet hole 12 of the jet nozzle 11 is washed with the washing water flowing in the direction. Also in this case, a cylinder 27 as a cover member is provided at the tip of the cylinder 10. Cylinder 27 and jet nozzle
A minute gap 28 as a minute space is formed between the space 11. The cleaning water film is held in the minute gap 28 by the surface tension.

The example shown in FIG. 5 has basically the same configuration as that of the above-described embodiment, and exhibits almost the same operation and effect. Also in this example, a cylinder 30 as a cover member is disposed at the tip of the cylinder 10. The cylindrical body 30 has an opening 30a. A minute gap 31 as a minute space is formed between the cylinder 30 and the ejection nozzle 11. And nozzle cleaning pipe
The washing water supplied from 29 passes through the opening 30a, and the minute gap 31
Leads to. Therefore, a film of the cleaning water is held in the minute gap 31 by the surface tension. The water supply member such as the above-described flocking portion may be provided on the inner surface of the cylindrical body 27 shown in FIG. 4 and the inner surface of the cylindrical body 30 shown in FIG.

[Effect of the Invention] In the jet nozzle device of the human body local cleaning device according to the present invention, the cleaning water is held by the water supply member of the cover member.
The problem that the ejection hole of the ejection nozzle becomes dirty with the solidified component of the washing water and the problem that the ejection hole of the ejection nozzle becomes clogged can be improved.
