DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing apparatus for washing a human body by jetting and discharging washing water from a spout.

[0002]

2. Description of the Related Art Conventionally, a plurality of water discharge modes have been provided in a human body cleaning apparatus. For example, Japanese Patent Application Laid-Open No. 52-512
56 or JP-A-59-151958 or JP-A-61-151958.
There is an example of -2636663. These are called multifunctional showers, and a plurality of water discharge modes can be made to appear on a single head singly or at the same time, and the trouble of detaching and replacing a plurality of devices according to the application can be omitted, and the water discharge that the user prefers will be provided. It is assumed that. The water spouting form is intended for normal body washing, and for the purpose of standard water spouting, a form of continuous water spouting at a discharge speed according to the supply water pressure, with a water stream having a predetermined streamline diameter, and a massage effect. Intermittent water discharge in which a water flow having a predetermined streamline diameter is intermittently discharged at a discharge speed according to the supply water pressure, with the aim of giving a unique effect such as giving a soft pressure feeling and improving cleaning performance There are bubble-mixed water spouting, which discharges water mixed with air bubbles in a water stream, striking hot water spouting, which expects a massage effect by hitting with a thick streamline, and mist water spouting, which ejects a large amount of fine mist-like water droplets. All of these are simple trajectories in which the trajectory of the water discharge is linearly continuous from the water discharge port to the hit point, and that the hit point does not change with time under the condition that the relative positional relationship between the water discharge port and the hit point does not change. They have common features in point. In the above-described cleaning device, each water discharge form is configured to be able to appear independently or simultaneously while being used at hand, and water discharge is performed according to various preferences from among the water discharge forms mounted while taking a shower. It is very convenient to switch.

[0003]

However, these cleaning apparatuses have no other than the above-mentioned water discharging mode. In particular, as shown in FIG. 6 as a form of water discharge expected to have a massage effect, the intermittent water discharge is a stimulus for a feeling of impact due to the continuous sparseness and denseness, and does not give a feeling of rubbing and loosening as in the case of finger pressure. For this reason, there is no means for providing when a feeling of rubbing and loosening such as by acupressure is required. Also, since the water spouting surface is usually provided with a water sprinkling angle in the direction of diffusion, it is inconvenient when it is necessary to apply water spouting to a size equal to or smaller than the water spouting surface due to structural restrictions, that is, a narrow local area If you need a spitting massage on
It was used while discharging water unnecessarily in places that were not necessary or where we did not want to get wet.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a cleaning apparatus for cleaning a human body by spraying and discharging cleaning water from a water discharge port, and using a finger pressure as required. The present invention proposes a cleaning device capable of providing a comfortable massage feeling. The second aspect of the present invention
An object of the present invention is to propose a cleaning apparatus which can be adjusted to enlarge or reduce a cleaning area as needed.

[0005]

In order to achieve the above object, in the first aspect, a swirling chamber for swirling the cleaning water and cleaning while revolving and rotating in the swirling chamber by the energy of the swirling flow. A cleaning device that includes a rotary nozzle that oscillates and discharges water and that performs cleaning of a human body by jetting and discharging cleaning water from a water discharge port at the tip of the rotary nozzle, wherein a rotation inclination angle adjusting unit of the rotary nozzle is provided. I do. Normally, a rotating nozzle receives a swirling force due to a swirling flow, and makes a revolving motion around the penetrating portion located near the water discharge part as a fulcrum, and the radius of rotation inclines the rotating nozzle by centrifugal force based on the revolving motion of the rotating nozzle. The angle is regulated. If the centrifugal force is sufficiently large without the angle restricting means, the rotating nozzle is inclined almost at right angles to the rotation axis, and the radius of rotation is maximized. On the other hand, when the centrifugal force is small, the inclination angle is small, and accordingly, the turning radius is also small. As described above, the centrifugal force is provided by the swirling flow, and the swirling flow is provided by the water supply. Therefore, when the water supply parameters such as the water supply amount, the water supply pressure, and the water flow velocity change, the inclination angle of the rotary nozzle is affected. With this configuration, by restricting the orbital position of the orbit by the orbital inclination adjusting means, the inclination angle with respect to the rotation axis is regulated, and the inclination angle of the rotary nozzle is maintained at a predetermined angle even if the water supply parameter changes. And the inclination angle can be changed even during use, so that it is possible to provide the spread of water discharge according to the user's request. Further, in the conventional cleaning device, there is a limit in narrowing the water discharge to a narrow area, and an area smaller than the width of the sprinkler plate is impossible, but the angle is made extremely small by providing a revolving inclination angle adjusting means. By doing so, it is possible to narrow down to the water discharge area of the water discharge aperture at the nozzle tip. Furthermore, a new massage feeling can be provided by operating the orbital inclination angle adjusting means continuously so that the water discharge area sequentially changes from enlargement to reduction and from reduction to enlargement while using the cleaning device.

Further, in the second aspect of the present invention, the cleaning device is characterized in that the angle regulating means is provided vertically movable in the swirl chamber, and regulates the angle from the upper direction of the rotary nozzle. With this configuration, the rotating nozzle that revolves in response to swirling energy tends to expand outward due to centrifugal force when the swirling force increases, but since the fulcrum of rotation is near the nozzle tip,
It tilts upward around the fulcrum, and pushes the angle regulating means reaching from above the rotating nozzle from below,
Therefore, it is not possible to incline further upward, so that the orbit of the orbit can be regulated. Further, since the angle restricting means is provided vertically movable in the swirl chamber, the restricting means is moved downward when reducing the inclination angle of the nozzle, and the restricting means is raised when increasing the inclination angle. Just move to. Further, according to the present method, there is an advantage that the friction can be reduced as compared with the means for restricting the rotation trajectory by the connection by the shaft, and the energy of the turning can be effectively maintained.

According to a third aspect of the present invention, the cleaning device is characterized in that the side surface of the rotary nozzle and the angle regulating means generate magnetic lines of force. With this configuration, a magnet is attached to the side of the rotating nozzle, a magnet is also attached to the angle regulating means, and the magnets are attached so that they have the same magnetic pole. Then, the orbit can be regulated. Furthermore, by using a strong magnet, the same effect can be obtained even if the angle regulating means is installed outside the swirl chamber. In this case, the element that disturbs the water flow in the swirl chamber can be reduced. There is an advantage of reducing energy loss due to turbulence.

According to a fourth aspect of the present invention, the cleaning apparatus is characterized in that a plurality of swirling chambers are provided, and a means for switching a turning direction to a right turning or a left turning in each of the turning chambers is provided. With this configuration, it is possible to select whether the trajectory of the water discharge flow is a right turn or a left turn. If the rotation is in the opposite hand direction, it becomes a pinching turn, so that another feeling of kneading can be provided. That is, if the rotation in the opposite hand direction is selected, the trajectories of the hit points of the right turn and the left turn are obtained. When the right turn rotates from 6:00 to 9:00 on the clock, the left turn is from 6:00 to 3:00. During this time, a right turn will continue to apply pressure to the impact area from lower right to upper left, while a left turn will continue to apply pressure to the impact area from lower left to upper right.
Therefore, pressurized massage from the lower right to the upper left and from the lower left to the upper right can be simultaneously performed, and it is possible to give a stimulating massage to loosen by finger pressure. In addition, since the hair of the human body grows while swirling, it is possible to select washing along the way of growth or washing against the hair. In other words, the swirl washing along the way of growth has a small wash-off resistance, so it gives a soft wash feeling without excessively stimulating pores, etc. It is effective for washing concave parts such as pores and washing with strong irritation.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a cleaning device used in a first embodiment of the present invention. The swirling chamber 1 creates a swirling flow by an inflowing water flow, an inlet 2 for supplying water to the swirling chamber 1, and a swirling flow. A rotary nozzle 3 for obtaining a rotational force by energy, and a water outlet 4 provided at the tip of the rotary nozzle
And a penetrating portion 5 configured so that the spout 4 can rotate through the ceiling of the swivel chamber. A handle 6 connected from the bottom outside the swirl chamber and a first fulcrum 7 connected to the handle 6 , A second fulcrum 9 provided at the center of the bottom of the rotary nozzle, and a support member 8 connecting the first fulcrum 7 and the second fulcrum 9. The handle 6 and the first fulcrum 7 are separated by a watertight seal (not shown) so that water in the swirling chamber does not leak outside.

The first fulcrum 7 and the second fulcrum 9 are connected so as to be rotatable vertically, and the first fulcrum 7 can be freely rotated in the direction of rotation of the rotary nozzle 3 by a swirling force. , The second fulcrum 9 is connected so as not to rotate. Accordingly, the support member 8 also rotates with the rotation of the rotary nozzle 3. On the other hand, 8 is connected to the rotary nozzle 3, so that the inclination of the rotary nozzle 3 can be changed depending on the preparation position of the handle 6. That is, when the handle 6 is moved up and down by an operation from outside the swiveling chamber, the angle of the support member 8 with respect to the rotary nozzle 3 changes, and the rotary nozzle 3 itself is rotatably supported by the penetrating portion 5. Rotate up and down. For example, according to FIG. 1A, by raising the handle 6, the first fulcrum 7 of the support member 8 is pushed up, but the support member 8 is moved to the second fulcrum 9 at the bottom of the rotary nozzle 3.
The nozzle is moved to increase the inclination because it is stopped by, and as a result, the rotary nozzle 3 is also stopped by the penetrating portion 5 so that the inclination is increased and the water outlet 4 also has a large inclination angle. The trajectory of water discharged from the camera becomes wide-angle. According to FIG. 1B, when the handle 6 is lowered, the first fulcrum 7 of the support member 8 is pulled in the direction of the bottom, and the support member 8 decreases its inclination.
The water discharge port 4 is also pulled toward the bottom and rises with a small inclination, and the water discharge port 4 is also formed at an angle.

Under the condition of water discharge, a turning force is applied to the rotary nozzle 3, so that the nozzle can open and close the water discharge angle while rotating. In this way, by operating the handle 6 up and down from outside during use, the inclination angle of the nozzle can be changed accordingly, and as a result, the water or hot water supplied from the inflow port 2 to the swirl chamber 1 is swirled. As a swirling flow in the room, the rotation energy is given to the rotary nozzle 3, and while revolving the rotary nozzle 3 and the support member 8, reaches the water discharge port 4 via a water passage (not shown) formed in the rotary nozzle 3, The cleaning area 10 at the hit point is changed while the water discharge angle is increased or decreased by operating the handle 6.

FIG. 2 is a sectional view of a cleaning apparatus used in a second embodiment of the present invention, in which a support portion 11 and a donut plate 12 are provided instead of the first fulcrum 7, the support member 8, and the second fulcrum 9. In the drawing, the donut plate 12 is arranged so as to be pressed from above the rotary nozzle 3 so as to prevent the rotary nozzle 3 from being inclined upward due to centrifugal force accompanying the rotation of the user. The donut plate 12 has a donut shape when viewed from the top in order to suppress a contact point that moves with time due to the rotation of the nozzle. In other words, the contact point of the rotary nozzle 3 that moves sequentially by rotation on the inner peripheral surface of the donut shape is pressed to maintain a predetermined inclination angle. The handle 6 is connected to a support 11 rising from the bottom of the swirl chamber, and the support 11 is further connected to support a donut plate 12. Therefore, the support portion 11 also moves the donut plate 1 by operating the handle 6 up and down.
Both move up and down. The handle 6 and the support 11
Is separated by a watertight seal (not shown) to prevent water in the swirl chamber from leaking to the outside, as in the first embodiment.

The centrifugal force acts as the rotary nozzle rotates, causing the nozzle to tilt.
Is moved up and down, the donut plate 12 moves up and down so that the contact points of the nozzles come into contact with each other, so that the inclination angle of the nozzles is restricted. When the handle 6 rises, the nozzle tends to rise upward, but is stopped by the penetrating portion 5 supporting the water discharge portion, so that the angle increases around the contact point near the penetrating portion 5. It turns, and when it goes down, it turns so that the angle becomes smaller. FIG. 2A shows a state in which the position of the donut plate 12 is raised by raising the handle 6, and as a result, the inclination angle of the rotary nozzle 3 is increased. The trajectory becomes wide-angle, and 10 behaves like cleaning a wide area. On the other hand, FIG. 2B shows a state in which the position of the donut plate 12 is lowered by lowering the handle 6, and as a result, the inclination angle of the rotary nozzle 3 is reduced, and the inclination of the water discharge part is also reduced. The trajectory of the water discharge becomes narrower, and 10 behaves like cleaning a narrow area.

Under the condition of water discharge, a turning force is applied to the rotary nozzle 3, so that the nozzle can open and close the water discharge angle while rotating. In this way, by operating the handle 6 up and down from outside during use, the inclination angle of the nozzle can be changed accordingly, and as a result, the water or hot water supplied from the inflow port 2 to the swirl chamber 1 is swirled. A swirling flow is generated in the room to apply rotational energy to the rotary nozzle 3 and revolve the rotary nozzle 3 to reach the water discharge port 4 through a water passage (not shown) formed in the rotary nozzle 3 and operate the handle 6. As a result, the washing area 10 at the impact point is changed while the water discharge angle is increased or decreased.

Further, as a more desirable thing of this embodiment, it is possible to consider a friction loss at a contact point. For example, the inner peripheral surface of the donut plate 12 as the contact portion or the contact surface of the rotary nozzle 3 may be made of a material having low sliding resistance such as POM, fluororesin, or a carbon-type material to reduce frictional resistance. A slidable ring-shaped structure is attached to the inner peripheral portion or the outer peripheral portion of the rotary nozzle 3 so as to have a role as a kind of bearing to reduce sliding resistance.

FIG. 3 is a sectional view of a cleaning apparatus used in a third embodiment of the present invention. The cleaning apparatus has a first magnet 13 at the tip of a donut plate 12 and has an action portion with the surface 13 on the rotary nozzle 3. The structure has the second magnet 14. 13 and 14 are permanent magnets, and are attached so that repulsive forces repelling each other in the direction of the line of magnetic force act. The centrifugal force caused by the rotation of the nozzle causes the tilt angle to increase,
On the other hand, when 13 and 14 approach each other, the repulsive force increases and opposes the centrifugal force. Further, since the restraining force can be applied to the inclination angle of the rotary nozzle 3 without contact by the repulsive force, the rotational radius can be adjusted without frictional resistance.

FIG. 3 (a) shows a state in which the position of 13 is raised by raising 6 and as a result, the inclination angle of the rotary nozzle 3 is increased. The trajectory becomes wide-angle, and 10 behaves like cleaning a wide area. Conversely, FIG. 3 (b) shows a state in which the position of 13 is lowered by lowering 6 and the inclination angle of the rotary nozzle 3 is reduced as a result. Are narrow and 10 behaves like cleaning a small area.

Under the condition of water discharge, since a turning force is applied to the rotary nozzle 3, it is possible to open and close the water discharge angle while rotating the nozzle. In this way, by operating the handle 6 up and down from outside during use, the inclination angle of the nozzle can be changed accordingly, and as a result, the water or hot water supplied from the inflow port 2 to the swirl chamber 1 is swirled. A swirling flow is generated in the room to apply rotational energy to the rotary nozzle 3 and revolve the rotary nozzle 3 to reach the water discharge port 4 through a water passage (not shown) formed in the rotary nozzle 3 and operate the handle 6. As a result, the washing area 10 at the impact point is changed while the water discharge angle is increased or decreased.

FIG. 4 schematically shows the turning direction switching mechanism of the cleaning apparatus used in the fourth embodiment of the present invention and the direction of the water flow in the turning chamber. Around the two swirl chambers 3 each having a rotary nozzle 3 (not shown) installed therein, a water guide plate 20 having a substantially triangular cross-section and a swirl chamber side wall 21 in contact with the inner periphery of the water guide plate 20 are provided. The swirl chamber side wall 21 is provided with an inflow opening 22, and the water guide plate 20 is fixed on a rotatable plate 23 rotatably provided on the outer periphery of the swirl chamber 3. One gear 25 and the remaining rotating plate 23 are connected to a second gear 27. Further, the first gear 25 and the second gear 27 are arranged so as to be interlockable via a third gear 26. Further, if necessary, the third gear 26 may be rotated
The first gear 25 and the second gear 27 are configured to be rotatable together with the rotation axis along the axis 0 and to rotate separately.

In the arrangement shown in FIG.
Of the water flow of the right turning chamber 3 causes a right turn due to the positional relationship between the water guide plate 20 and the inflow port 22. As a result, the rotating nozzle (not shown) rotates in each of the turning directions,
Similarly, the trajectory of the hit point of the water discharge appears in a state where the left turn and the right turn are arranged side by side. At this time, the clockwise turn is 9 from 6 o'clock on the clock.
When turning to the left, the left turn will turn from 6 o'clock to 3 o'clock, during which time the right turn will continue to apply pressure to the hit area from the lower right to the upper left, while the left turn will start from the lower left Continue to apply pressure to the hit area toward the upper right. Therefore, pressurized massage from the lower right to the upper left and from the lower left to the upper right can be simultaneously performed, and it is possible to give a stimulating massage to loosen by finger pressure. In particular, when this operation is performed with a thick streamline, the feeling of pressing with both thumbs becomes closer, and the sense of acupressure increases.

Further, the first gear 25 or the second gear 27
When the rotating plate 23 provided around the swirl chamber 3 is rotated by a rotating means (not shown) from the outside, and stopped at a position where the swirling flow direction is changed by a not-shown stopping means, the direction of the swirling flow is changed. Is changed, for example, only a right turn or only a left turn. Since the hair of the human body grows while swirling, it is possible to select the washing along the way of growth or the opposite washing. In other words, the swirl washing along the way of growth has a small wash-off resistance, giving a soft wash feeling without excessively stimulating pores and the like.
It is effective for washing concave parts such as pores and washing with strong irritation.

The mechanism for changing the turning direction at this time is shown in FIG.
This will be described with reference to (c) and (d). The arrow in the figure indicates the direction of the water flow. FIG. 4C shows that the water guide plate 20 is a swivel chamber side wall 21.
Is located close to the side A of FIG. 1, a water channel having a left-turning element is formed between the water guide plate 20 and the swirl chamber side wall 21, while in FIG. Since it is located close to the B side, a water channel having a right-turning element is formed between the water guide plate 20 and the turning chamber side wall 21. That is, the turning direction is determined by which angle the inclined side wall surface of the water guide plate 20 has with respect to the inflow water. Therefore, the water guide plate 20 may have a substantially V-shaped cross section other than a substantially triangular shape.
