DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bidet nozzle,
The present invention relates to a local cleaning device for toilet facilities provided with a cleaning water injection nozzle such as a buttocks dedicated nozzle.

[0002]

2. Description of the Related Art As shown in FIG. 2, a local cleaning device is a device installed in a toilet 30 and has a local nozzle such as a bidet nozzle 1a for women and a buttocks nozzle 1b for normal use. At least one washing nozzle is provided on the lower rear side of the toilet seat 31, and one of the nozzles extends when used and performs washing by spraying hot water to a local part.

FIG. 3 shows a basic configuration of a local cleaning device.
The water storage tank 2 is connected to the hot water tank 3 by a water path 5c via a pump 4, and the hot water tank 3 is also connected to an on-off valve 6 which is an electromagnetic valve by another water path 5d via the pump 4. Further, the opening / closing valve 6 is connected to the bidet nozzle 1a by a water channel 5a and to the buttocks nozzle 1b by a water channel 5b. Therefore, at the time of use, ordinary water supplied from the water supply tank 2 or a water supply pipe (not shown) is sent to the hot water tank 3 via the water channel 5c by the pump 4, and is heated by the heater 50 in the hot water tank 3. It is always available as hot water. If the pump 4 is operated by an external operation, the bidet exclusive nozzle 1 is passed from the water channel 5d via the on-off valve 6 and the water channel 5a.
a or the nozzle 1b for the buttocks through the water channel 5b
The warm water is sent to one of them as washing water.

[0004] The bidet-specific nozzle 1a comprises a cylinder 7 and a slider 8. At the tip of the slider 8, a bidet-specific attachment 15a having a plurality of ejection holes is detachably mounted, and at the rear end, an opening is provided. Has been given.
A water supply lid 9 having a water supply port 11 is attached to a rear end opening of the cylinder 7, and a slider 8 is fitted into the cylinder 7 so as to be able to enter and exit from the front end opening of the cylinder 7. By providing a spring 12 between the cylinder 7 and the slider 8, the slider 8 is urged in the backward direction, that is, in the direction of the water supply port 11. The buttocks-only nozzle 1b has the same configuration as the above-mentioned bidet-only nozzle 1a, except that a buttocks-only attachment 15b is detachably attached to the tip of the slider 8.

Therefore, when the hot water in the hot water tank 3 flows into the cylinder 7 of the bidet nozzle 1a through the on-off valve 6 by the pump 4, the slider 8 moves the cylinder 7 against the spring 12 by the pressure of the hot water. It is pushed forward from the front end opening. When the slider 8 reaches the forward limit, the cylinder 7 closed by the slider packing 13
Internal pressure rises and the attachment 15a dedicated to the bidet at the tip
Warm water, that is, cleaning water, is jetted vigorously to the local area. Next, if the on-off valve 6 shuts off hot water, the slider 8
Is pulled back into the cylinder 7 by the spring 12. When hot water flows into the buttocks-only nozzle 1b by switching the on-off valve 6, the same operation as that of the above-mentioned bidet-only nozzle 1a is performed, but in this case, hot water is injected from a single ejection hole of the buttocks-only attachment 15b.

Although the basic structure of the local cleaning device is as described above, the cylinder 7 has a certain internal pressure during the forward or backward movement of the nozzle. Wet parts will impair the comfort of the user. Therefore, various local cleaning apparatuses have been conventionally proposed in order to solve the above problems.

FIG. 4 shows a conventional example. In the stop state as shown in FIG. 4A, an opening / closing valve 23 that closes the inflow port 22 of the washing water by a valve body 21 urged in a retreating direction by a spring 20 is provided at the rear end opening of the slider 8. is set up. For example, washing water is supplied from the water supply port 11 of the bidet nozzle 1a, and the slider 8 is moved by the spring 12
In the process of extruding against the valve body 2,
Reference numeral 1 denotes a state in which the inflow port 22 is closed, and the inflow of the washing water into the slider 8 is prevented.

As shown in FIG. 4B, if the cleaning water is further supplied after the slider 8 reaches the forward limit, the internal pressure of the cylinder 7 rises, and the valve 21
Push forward. At this time, a large amount of washing water flows into the slider 8 from the inflow port 22 for the first time, and the injection to the local area starts from the injection hole of the bidet-specific attachment 15a.
Next, when the supply of the washing water from the water supply port 11 is stopped, the internal pressure of the cylinder 7 is reduced, and the slider 8 is retracted by the spring 12 with the valve body 21 closing the opening 22 by the spring 20. . In this way, the injection of cleaning water can be suppressed during the forward and backward movements of the slider 8.

FIG. 5 shows another conventional example. By providing a pin body 24 extending straight from the rear of the slider 8 and further providing a suppression ball 25 that is penetrated by the pin body 24, in a stopped state, as shown in FIG. Are engaged with the rear end opening of the slider 8. When the washing water is supplied into the cylinder 7, the slider 8 is pushed forward while being engaged with the restraining ball 25. At this time, the inflow of the washing water into the slider 8 is prevented. The restraining ball 25 is locked at the tip of the pin body 24 shortly before the slider 8 reaches the forward limit, so that when the slider 8 reaches the forward limit as shown in FIG. The fuel freely flows from the rear end opening, and is injected into a local area. Next, when the supply of the cleaning water is stopped, the slider 8 starts to retreat by the spring 12, and the restraining ball 25 is again engaged with the rear end opening, thereby preventing the inflow of the cleaning water by the engagement. 8 retreats. Slider 8 in this way
During the forward movement and the backward movement, it is possible to suppress the injection of the washing water.

[0010] However, in these conventional local cleaning apparatuses, although it is possible to inject cleaning water into the local area without wetting unnecessary parts, the means used for that purpose is constituted by a plurality of parts. Therefore, not only a complicated assembling process is required, but also the cost must be high.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a simple structure which makes it possible to spray cleaning water only to a local part without wetting unnecessary parts. It is an object to provide a cleaning device.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the accompanying drawings. 1 and 6 to 13 show an example of an embodiment of the present invention. FIG. 1 (b)
As shown in the drawings, the basic configuration of the cleaning nozzles 1a and 1b is substantially the same as that described in the conventional example. However, in this example, the injection of the cleaning water during the forward or backward movement of the slider 8 is suppressed. For this purpose, a disc-shaped suppression valve 26 is used.

As shown in FIG. 9, the control valve 26 is provided with a notch 40 in a substantially S-shape, and the portions 26a and 26b surrounded by the notch 40 only when a pressure higher than the opening pressure is applied. Are extruded in the pressure direction, so that the cuts 40 are opened. In a state where the suppression valve 26 is attached to the rear end opening of the slider 8 as shown in FIGS. 12 and 13, for example, if cleaning water is supplied to the buttocks-only nozzle 1 b, the suppression valve 26 and the slider 8 move forward due to the water pressure. Extruded. If the opening pressure of the suppression valve 26 is set to a value larger than the water pressure at this time, the notch 40 does not open during the forward movement, and therefore, the inflow of the washing water into the slider 8 can be prevented.

As shown in FIGS. 7 and 11, when the slider 8 reaches the forward limit and the cleaning water is further supplied, the internal pressure of the cylinder 7 sealed by the slider packing 13 rises, and the water pressure applied to the suppression valve 26 is increased. When the pressure exceeds the pressure, a large amount of cleaning water flows into the slider 8 through the opening of the cutout 40, and the cleaning water is vigorously jetted from the attachment dedicated to the buttocks 15b attached to the distal end to the local area.

Next, when the supply of the washing water is stopped, the water pressure applied to the suppression valve 26 drops and falls below the opening pressure, thereby closing the opening of the cut 40, and the spring 12 causes the buttocks dedicated nozzle 1b to start retreating. The operation returns to the stop state shown in FIGS. Therefore, the washing water does not flow into the slider 8 during the retreat.

As described above, by simply attaching the suppression valve 26 having the above-described configuration to the rear end opening of the slider 8, when the slider 8 reaches the forward limit, that is, when the slider 8 reaches the fully extended state, the distal end of the attachment 15b dedicated to the buttocks from the distal end to the local part. Flush water, and unnecessary spray can be prevented while the slider 8 is moving forward and backward. Here, the buttocks-only nozzle 1b has been described, but the same effect can be obtained with the same configuration in the bidet-only nozzle 1a. However, in the case of the bidet dedicated nozzle 1a, the washing water is jetted from the bidet dedicated attachment 15a attached to the tip. Also, nozzle 1
Which of a and 1b is operated depends on the water flow control by the on-off valve 6 shown in FIG.

FIG. 14A shows another example of the control valve 26. In the local cleaning device, the used nozzles 1a,
If the washing water remaining in 1b is not discharged, the user may feel uncomfortable because the temperature is lowered at the next use. The control valve 26 of this example has a cut 40
A small opening 41 is provided by forming a gap in the whole,
At the time of stopping, outside air can be taken into the slider 8 through the opening 41, so that the cold washing water can be naturally discharged by the next use. FIG. 14 (b)
5 shows another example of the suppression valve 26. In this case, a gap is formed in a part of the cut 40 to form the opening 41, and the operation and effect are the same as those of the other examples.

[0020]

As described above, according to the first aspect of the present invention, the height of the washing water spouted during the forward and backward movement of the slider is suppressed, so that unnecessary parts are wetted and the user is prevented from getting wet. You can clean the local area without giving a pleasant feeling,
In addition, since it is only necessary to attach a plate-shaped suppression valve in this manner, the assembly process can be simplified and the cost can be reduced.

According to the second aspect of the present invention, the washing water having a reduced temperature remaining in the slider after use is discharged so that the washing can be performed every time using the washing water having a suitable temperature. It is possible to do.
