Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a local cleaning device which is attached to a toilet bowl and performs anal cleaning and female bidet cleaning.

[Conventional technology]

As the nozzle mechanism of the local cleaning apparatus, there are a pressure regulating valve type shown in the vertical sectional view of FIG. 6 and an inlet matching type shown in the vertical sectional view of FIG. In the pressure regulating valve type nozzle mechanism 1 shown in FIG. 6, the cleaning nozzle 3 is mounted in the outer cylinder 2 so as to be able to project and retract, and is attached in the retracting direction (leftward in FIG. 6) by the return spring 4. I am energetic. On the rear end side of the cleaning nozzle 3, a pressure regulating valve 6 which is normally closed by a spring 5 is provided. When the inflow opening 7 provided on the rear end side of the outer cylinder 2 is communicated with the water supply side, the cleaning nozzle 3 is first pushed out by the water pressure supplied. And
When the cleaning nozzle 3 is stopped in the most protruding state, the water pressure in the outer cylinder 2 rises and the pressure regulating valve 6 is opened.
Therefore, the water supplied from the water supply side flows into the cleaning nozzle 3 and is ejected from the ejection holes 8 at the tip toward the local part of the human body.

In addition, the nozzle mechanism 11 of the inlet matching type shown in FIG.
A connection opening 12 is formed on the peripheral side surface of the outer cylinder 2 on the front end side, and an inflow hole 13 is formed on the peripheral side surface of the cleaning nozzle 3 on the rear end side. Then, connect the connection opening 12 of the outer cylinder 2 to the connection pipe 14
Is connected to the water supply side. Other configurations are the sixth
It is the same as the nozzle mechanism 1 shown in the figure. This nozzle mechanism 11
In this case, when the inflow opening 7 of the outer cylinder 2 is communicated with the water supply side, the cleaning nozzle 3 first projects, and the connection opening 12 of the outer cylinder 2 and the inflow hole 13 of the cleaning nozzle 3 are aligned at the most projecting position. To do. Therefore, the cleaning water is supplied from the connection pipe 14 through the connection opening 12 and the inflow hole 13 into the cleaning nozzle 3, and is ejected from the ejection hole 8 at the tip toward the local part of the human body.

[Problems to be solved by the device]

However, in the conventional nozzle mechanism 1 including the pressure regulating valve 6 shown in FIG. 6, the projecting operation of the cleaning nozzle 3 and the jetting of cleaning water are performed by the same supply water pressure using the same system path. Is going. Therefore, for local cleaning, the cleaning nozzle 3 must first be caused to project, and then the pressure regulating valve 6 must be opened to eject cleaning water. Therefore, there is a drawback in that the discharge pressure of the wash water is set to be at least higher than the water pressure for opening the pressure regulating valve 6, and becomes higher than necessary. That is, it is impossible to set the discharge pressure of the wash water to a low pressure, and for example, a user with hemorrhoid or the like has a drawback that the water force of the wash water that hits the local area becomes too strong and causes pain. In addition, since the discharge pressure must be increased, a separate pressure pump or the like is required, and it is impossible to use the nozzle mechanism 1 as it is in an area where the supply pressure of tap water is low. There was a drawback.

Further, a conventional nozzle mechanism of the inlet matching type shown in FIG.
In No. 11, the cleaning water is supplied into the cleaning nozzle 3 through a separate system path after the cleaning nozzle 3 is projected, and theoretically the discharge pressure of the cleaning water can be set low. . However, this type of nozzle mechanism 11 allows the outer cylinder 2 and the cleaning nozzle 3 to move while the cleaning nozzle 3 is projecting.
The supply water pressure acts between the outer cylinder 2 and the cleaning nozzle 3 via the connection pipe 14 and the connection opening 12, and a large amount of cleaning water leaks from between the outer cylinder 2 and the cleaning nozzle 3. Therefore, the loss of the supply water pressure is large, and it is necessary to set the supply water pressure to an excessively high level, which has the same drawback as that of the pressure regulating valve type nozzle mechanism 1 shown in FIG. That is, a pressurizing pump for increasing the supply water pressure was required separately. Moreover, if the supply water pressure is set to an excessively high value, the connection opening 12 and the inflow hole 13
In the state where the cleaning water is discharged from the ejection hole 8 in conformity with the above, the supply water pressure set to a high level becomes the discharge pressure of the cleaning water as it is, and the user having hemorrhoids or the like is forced to suffer. There was a drawback. Further, there is a drawback that it cannot be used as it is in an area where the supply water pressure is low.

[Means for Solving the Problems]

SUMMARY OF THE INVENTION The present invention has been improved and removed in view of the above-mentioned problems of the related art, and by eliminating the loss of the supply pressure of wash water, a pressurizing pump is unnecessary and the discharge pressure of wash water is set low. It is intended to provide this kind of local cleaning device.

Thus, the means adopted by the present invention to solve the above-mentioned problem is to push the cleaning nozzle by applying the supply water pressure into the outer cylinder, and the cleaning nozzle inflow hole and the outer cylinder at the position where the cleaning nozzle is most protruded. In a local cleaning device equipped with a nozzle mechanism adapted to supply the cleaning water into the cleaning nozzle by matching the connection opening formed on the peripheral side surface of the outer cylinder, an extrusion water channel is connected to the rear end side inflow opening of the outer cylinder. And a connection water passage that is connected to the connection opening of the outer cylinder are separately provided, and the extrusion water passage and the washing water passage are connected by a bypass passage, and an orifice is provided in the middle of the bypass passage. The inflow sides of the water channel for extrusion and the water channel for cleaning are connected to a water supply means capable of switching high-pressure water supply or low-pressure water supply.

[Action]

When the cleaning nozzle is operated to project, the water channel for extrusion is connected to the supply water source on the low pressure side. Therefore, it is possible to perform the projecting operation without waste by using the minimum required water pressure. During this projecting operation of the cleaning nozzle, the water channel for extrusion may be connected between the outer cylinder and the cleaning nozzle via the bypass passage, which may result in loss of supply water pressure. Is provided and does not matter.

On the other hand, when the cleaning water is discharged with the cleaning nozzle protruding most, the inflow side of the extrusion water channel is closed and the cleaning water channel is communicated with the supply water source on the high pressure side. This causes the high-pressure supply water pressure to act from the cleaning water channel to the extrusion water channel via the bypass channel, pressing the rear end side of the cleaning nozzle so that the cleaning nozzle does not retract during the cleaning operation. Moreover, in the cleaning operation, the cleaning nozzle completes the protruding operation,
After the connection opening of the outer cylinder and the inflow hole of the cleaning nozzle are aligned, the cleaning water passage is connected to the supply water source on the high pressure side, so that the water pressure can be arbitrarily changed. Therefore, since it is not necessary to increase the supply water pressure more than necessary as in the conventional case, a pressurizing pump or the like is not required and the water pressure of the wash water does not become too strong. In other words, comfortable use is possible.

〔Example〕

The structure of the present invention will be described below with reference to the embodiments shown in the drawings. The same reference numerals as in the conventional case are the same members.

FIG. 1 is a vertical cross-sectional view showing the entire local cleaning device 21 according to the first embodiment of the present invention. As shown in the figure, in this embodiment, the inflow opening 7 provided at the rear end side of the outer cylinder 2 is connected to the extrusion water passage 15 and the connection opening 12 provided at the front end side of the outer cylinder 2 is connected. Is connected to the washing water channel 16. Then, the middle of the water passage 15 for extrusion and the water passage 16 for washing are connected by a bypass passage 17, and the bypass passage
An orifice 18 is installed in the middle of 17. Further, in this embodiment, the inflow side of the extrusion water channel 15 and the cleaning water channel 16,
It is connected to a three-port water supply valve 19 as a water supply means capable of switching between high-pressure water supply and low-pressure water supply. One port of the water supply valve 19 is communicatively connected to the hot water tank 20. The hot water tank 20 controls the heater so that the water in the tank always has a temperature within a certain fixed range, and the hot water inside is pushed out by the water supply pressure.

The water supply valve 19 has a fixed disk 22 having an eccentric opening 30 and an eccentric opening 31, as shown in the longitudinal sectional view of FIG. 2, the exploded perspective view of FIG. 3, and the horizontal sectional plan view of FIG. A flow control valve is composed of the movable disk 23 and the outflow port.
A low flow rate is discharged from 24 at a low pressure, and a high flow rate is discharged from the outflow port 25 at a high pressure.
The fixed disk 22 and the movable disk 23 have an eccentric opening 30 when the handle 26 is switched to the high pressure side.
And 31 are matched. 2 and 3, reference numeral 26 is a handle, 27 is a handle shaft, 28 is an auxiliary valve body that connects the handle shaft 27 and the movable disk 23, and 29 is an inflow port.

Next, an operation mode of the first embodiment device 21 configured as described above will be described.

First, when the human body is locally washed, the handle 26 is rotated, for example, in the clockwise direction in FIG. 3 from the closed state shown in FIGS. 2 and 3, so that the opening 31 of the movable disc 23 gradually moves toward the fixed disc 22. The hot water from the hot water tank 20 passes through the valve chamber space 32 and is discharged to the outflow port 24. In this case, the opening 31 of the movable disk 23
The overlap between the opening and the opening 30 of the fixed disk 22 is only a part, and eventually the action of the throttle reduces the water supply pressure and the discharge flow rate. The small amount of warm water is supplied from the outflow port 24 to the inflow opening 15 of the outer cylinder 2 through the extrusion water passage 15. Therefore, the low-pressure hot water acts on the rear end surface of the cleaning nozzle 3, and the cleaning nozzle 3 gently projects. In addition, at the time of this protruding operation of the cleaning nozzle 3,
A part of the hot water reaches the washing water passage 16 from the extrusion water passage 15 through the bypass passage 17, flows into between the outer cylinder 2 and the washing nozzle 3, and leaks from the tip fitting portion of both, resulting in unnecessary pressure loss. There is a risk of becoming. However, in this embodiment, the orifice 18 is installed in the middle of the bypass passage 17, the hot water outflow from the extrusion water passage 15 to the washing water passage 16 is negligibly small, and there is no need to worry. is there.

On the other hand, when the cleaning water is discharged in the state where the cleaning nozzle 3 is most protruded (the connection opening 12 of the outer cylinder 2 and the inflow hole 13 of the cleaning nozzle 3 are aligned), the handle 26 of the water supply valve 19 is rotated. Then, the opening 31 of the movable disk 23 is operated so as to match the opening 30 of the fixed disk 22. As a result, a large amount of hot water (wash water) at high pressure is discharged from the hot water tank 20 to the outflow port 25. In this state, the inflow side of the extrusion water channel 15 is closed. Therefore, the high-pressure hot water is supplied from the outflow port 25 to the cleaning water passage 16 and flows into the cleaning nozzle 3 through the connection opening 12 of the outer cylinder 2 and the inflow hole 13 of the cleaning nozzle 3. Then, it is ejected from the ejection holes 8 of the cleaning nozzle 3 toward the local part of the human body to clean the local part of the human body.

During this cleaning operation, the water pressure in the cleaning water channel 16 acts on the rear end surface of the cleaning nozzle 3 from the extrusion water channel 15 through the bypass channel 17 and presses it, so that the cleaning nozzle 3 does not retreat during the cleaning operation. I am trying. Moreover, since the cleaning operation is performed after the connection opening 12 of the outer cylinder 2 and the inflow hole 13 of the cleaning nozzle 3 are aligned with each other, hot water does not leak from the gap between the outer cylinder 2 and the cleaning nozzle 3. It is not necessary to set the hot water discharge pressure higher than necessary. Therefore, a pressurizing pump or the like is unnecessary, and the water pressure of the washing water does not become too strong. That is, even a user who has hemorrhoids can use it comfortably. Even in areas where tap water source pressure is low, this local cleaning device
It is possible to use 21 as it is. The discharge pressure of the hot water can be adjusted freely by rotating the handle 26 and changing the ratio of the opening area between the opening 31 of the movable disk 23 and the opening 30 of the fixed disk 22. is there.

FIG. 5 is a vertical sectional view showing the whole of the local cleaning apparatus 41 according to the second embodiment of the present invention. In this embodiment, a low-output pump 33 and a high-output pump 34 are used as water supply means capable of switching between high-pressure water supply and low-pressure water supply, and these are electrically switched and selectively used. The rest of the configuration and the basic operation mode are the same as in the case of the above-described first embodiment, and the description thereof is omitted here.

By the way, the present invention is not limited to the above-described embodiments, but can be appropriately modified. For example, two types of solenoid valves having different discharge capacities may be used as the water supply means capable of switching the high-pressure water supply or the low-pressure water supply. Further, as the means for pressurizing the supply water pressure to the hot water tank 20, the case where the original pressure of tap water is used as it is has been described, but a small pressurizing pump may be used.

[Effect of device]

As described above, in the present invention, there is no loss of the supply water pressure for causing the cleaning nozzle to project, and the supply water pressure can be set low. Therefore, it is not necessary to install a high-pressure pressurizing pump as in the prior art, and the water pressure of the washing water can be freely changed, so that even a user with hemorrhoids can use it comfortably. Furthermore, the local cleaning apparatus of the present invention can be used as it is even in an area where tap water has a low original pressure, which is convenient.
