Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning water injection mechanism for intermittently ejecting cleaning water from a nozzle device in a human body local cleaning device installed in a toilet or the like.

[0002]

2. Description of the Related Art In recent years, a human body local cleaning device has become an increasingly important daily life device as health-oriented and cleanliness-oriented items in daily life have increased. The spray pattern of the cleaning water of the human body local cleaning device is particularly important, and various devises have been made so far, and the intermittent cleaning described in the present invention is one of them.

In the intermittent cleaning, the strength of the cleaning water or the height of the nozzle portion for ejecting the cleaning water is intermittently changed at a predetermined time interval to give a comfortable stimulus to the user's local area, thereby eliminating defecation. The purpose is to promote or promote local blood circulation.

As a conventional device of this type, Japanese Patent Laid-Open No. 2000-2000
-265523. In this device, as shown in FIG. 6, a space 14 and a jet hole 15 are provided at a tip portion 11 of a nozzle portion 10 which constitutes a cleaning water injection device 1 of a human body local area cleaning device. Rotor body 2 in space 14
Is rotatably accommodated and is communicated with the water conduit 12 by a communication portion 13 which is a flow path formed along the inner wall of the cylindrical space 14. The rotor body 2 is shown in FIG.
As shown in FIG. 2, the blade surface 21 extends in the vertical direction, the shield plate 22 extends in the horizontal direction, and the projection 23. An open space 24 is formed by the inner peripheral surface, the inner bottom surface of the space 14, the ceiling surface on which the ejection holes 15 are formed, and the two blade surfaces 21 of the rotary blade body 2. A closed space 25 is formed by the inner peripheral surface of the space 14, the inner bottom surface, and the lower surface of the shield plate 22.

According to this structure, the washing water tank (not shown) is supplied through the water conduit 12 at a predetermined pressure, and the communicating portion 1 is provided.
The cleaning water that has passed through 3 and flowed into the space 14 in which the rotor body 2 is housed exerts a pressure on the blade surface 21 to rotate the rotor body 2. Of the wash water that has flowed into the space 14, the wash water that has flowed into the open space 24 is directly communicated with the open space 24 and the ejection holes 15 as the rotary vane body 2 rotates, and a predetermined amount of wash water is ejected from the ejection holes 15. It is ejected to the outside of the device 1. Of the wash water that has flowed into the space 14, the wash water that has flowed into the closed space 25 is not directly connected because the closed space 25 and the ejection holes 15 are shielded by the shield plate 22, and the inner peripheral surface of the space 14 and the rotor blades are not communicated. Since it flows out from the ejection hole 15 through the gap between the outer ends of the body 2, the flow rate from the ejection hole 15 is restricted and the cleaning water is weakly ejected.

Cleaning water spraying device 1 for this human body local cleaning device
In order to sufficiently bring out the effect of the intermittent injection, it is desirable to limit the cleaning water as much as possible when the jetting hole 15 is blocked by the shield plate 22, so that the upper surface of the shield plate 22 and the jetting hole 15 are washed. Gap 20 and space 1 with water inlet
The gap between the inner diameter of No. 4 and the outer diameter of the rotor body 2 was configured to be as small as possible.

[0007]

However, in the above-mentioned prior art, the shield plate of the rotary blade body makes a rotary motion immediately before the inlet of the ejection hole to complicate the flow of the washing water, and in particular, in the rotary blade body. Since the gap between the upper surface of the shielding plate and the wash water inlet of the jet hole is made small, the flow rate in the weak jet state can be sufficiently reduced, but it is weak due to the disturbance of the flow in the jet hole. However, there is a problem that when the cleaning water is sprayed, a part of the sprayed water is scattered in a direction different from the angle of the spray hole.

[0008] If such washing water is scattered, water droplets will adhere to parts other than the human body part where the washing is desired.
There is a possibility that the user may feel uncomfortable.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a cleaning water mechanism for intermittent cleaning by suppressing the scattering of cleaning water in a compact human body local cleaning device having a simple structure and low cost. .

[0010]

A first technical means taken to solve the above technical problem is, as shown in claim 1, an ejection hole for ejecting washing water to a human body part and the ejection hole. A water conduit communicating with a hole to guide the cleaning water, a space communicating with the ejection hole and the water conduit, the cleaning water housed in the space and supplied to the space from the water conduit. A human body part including a wing surface that receives a force to generate a rotational force, and a rotary wing body having a communication limiting mechanism that intermittently limits the communication between the ejection hole and the space portion in response to rotation by the wing surface. In the cleaning water injection mechanism of the cleaning device, a cleaning water rectifying mechanism that rectifies the cleaning water flowing between the ejection hole and the communication limiting mechanism is provided, and the cleaning water injection mechanism of the human body local cleaning device is configured. That is what I did.

According to the above construction, the cleaning water that has passed through the water conduit is introduced into the space in which the blade surface and the rotor blade are housed,
The flow velocity of the wash water acts on the blade surface to move toward the ejection hole while rotating the rotor body, but at this time, it passes through the communication restriction mechanism that intermittently restricts the communication between the ejection hole and the space according to the rotation. . Since the flow rate of the washing water is intermittently and rapidly reduced immediately before the ejection hole by this communication limiting mechanism, a large turbulence easily occurs in the flow of the washing water. In the cleaning water jetting mechanism of the human body local cleaning apparatus of the present invention, even if the cleaning water passes through the communication limiting mechanism and is suddenly squeezed, a cleaning water rectifying mechanism that rectifies the cleaning water immediately after that is provided. As described above, when the flow rate of the washing water is limited by the communication limiting mechanism, the turbulence of the flow can prevent scattering from the ejection holes.

A second technical means taken to solve the above-mentioned technical problem is, as described in claim 2, a communication space between the space portion and the ejection hole according to the rotation of the rotor body. 2. The human body local part according to claim 1, which is a plate-shaped member integrally provided on the rotary wing body that intermittently restricts the cleaning water rectifying mechanism provided on the plate-shaped member. That is, the cleaning water injection mechanism of the cleaning device is configured.

According to the above construction, the cleaning water that has passed through the water conduit is introduced into the space, and is introduced into the inside of the rotary blade body that rotates at the flow speed of the cleaning water toward the ejection holes. The flow rate of the wash water is sharply reduced by the plate-like member of the rotary blade body that intermittently limits the communication between the ejection hole and the space. However, since the plate-shaped member is provided with the cleaning water rectifying mechanism, the flow of the cleaning water whose flow rate is sharply reduced is rectified again and can be ejected from the ejection hole without being disturbed.

A third technical means taken to solve the above technical problem is as set forth in claim 3, wherein the flush water rectifying mechanism is arranged in parallel with the rotation direction of the plate member. The cleaning water jetting mechanism of the human body local cleaning apparatus according to claim 2 is a road.

According to the above construction, the wash water that has passed through the water conduit is introduced into the space, and is introduced into the inside of the rotor blade that rotates at the flow rate of the wash water toward the ejection holes. The flow rate of the wash water is sharply reduced by the plate-like member of the rotary blade body that intermittently limits the communication between the ejection hole and the space. However, the plate-like member is formed with a predetermined flow path provided in parallel with the rotation direction associated with the rotation of the rotor body,
Since the wash water is rectified by constantly passing through this flow path before flowing into the jet holes, stable jetting can be performed without disturbing the flow.
