Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an improvement in a sanitary cleaning device that cleans private parts by jetting cleaning water heated to an appropriate temperature.

[Conventional technology]

In recent years, various types of sanitary cleaning devices have been used that are attached to flush toilets and spray pre-purified water heated to an appropriate temperature to the private parts to clean the private parts. For example, as shown in FIG. 11, the sanitary cleaning device includes a retractable nozzle device 4 in which a cleaning water spout 3 is located in a direction corresponding to the private parts within a goo song 2 fixed to the rear upper surface of the toilet bowl 1. The nozzle body 6 shown by the two-dot chain line in FIG. The cleaning water is extruded diagonally downward to the private parts, and when the nozzle main body 6 is pushed out to the maximum extent, the cleaning water is jetted toward the private parts from the spout 3 at the tip of the nozzle main body 6 to clean the private parts. There is.

[Problems to be solved by the invention]

However, the above-mentioned sanitary cleaning device only has the function of cleaning the private parts by automatically extending the nozzle body 6 to the cleaning position and spouting cleaning water when the private part cleaning operation is performed. Therefore, there were the following problems. (I) When the nozzle device 4 is not in use, the nozzle body 6 is housed in the casing 2;
Since the tip of the nozzle is installed with its tip exposed inside the toilet bowl 1 through the opening of the casing 2, the nozzle can be used when discharging filth or sewage with washing water during or after using the toilet, or when cleaning private parts. When the main body 6 protrudes into the toilet bowl 1, sewage, etc. in the toilet bowl I is scattered and sprayed into the spout 3 of the nozzle body 6.
There was a risk that it might stick to the periphery. (2) After the cleaning water is ejected, the nozzle body 6 is pulled back into the nozzle device 4 by the force of a compression spring (not shown) inserted in the nozzle device 4 because the supply of cleaning water is cut off. That is, although the nozzle body 6 is housed in the casing 2, in this case, the nozzle body 6 is filled with cleaning water, and when the nozzle body 6 returns to its original position, a part of the cleaning water flows into the cleaning device body. However, as the nozzle body 6 retreats, most of it is ejected from the small-diameter spout 3 like a water gun, licking the user's buttocks, causing discomfort to the user and damaging clothes. There was a risk of getting some parts wet.

[Purpose of the invention]

The present invention eliminates the above-mentioned drawbacks and, before using the sanitary cleaning device,
Later, it is an object of the present invention to provide a sanitary cleaning device equipped with a sanitary nozzle device that constantly maintains the tip of the nozzle body clean by washing the periphery of the spout at the tip of the nozzle body with water for local cleaning. be.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a water inlet and a self-cleaning nozzle that is disposed on the outside of the nozzle device and sprays cleaning water from the tip to the periphery of the spout of the nozzle body, immediately before the water inlet of the nozzle device. An electromagnetic switching valve is installed to switch the flow path of the cleaning water supplied to the self-cleaning nozzle side, and this electromagnetic switching valve is driven and controlled for a certain period of time by a command signal from the control device before and after using the sanitary cleaning device. The nozzle body is always kept clean and private parts are washed hygienically by opening the flow path and spraying the washing water for private parts washing around the jet nozzle rim of the nozzle body to wash the tip of the nozzle body. It is characterized by the following.

[Practical example]

Hereinafter, practical examples of the present invention will be explained with reference to FIGS. 1 to 10. In FIGS. 1 to 5, the sanitary cleaning of the present invention! As shown in FIGS. 1 and 2, the J holder 11 is attached to the rear upper surface of the toilet bowl 12, and a toilet seat 14 and a toilet lid 143 are pivotally attached to the front side of the casing 13 so as to be able to freely vibrate. There is. Moreover, as shown in FIG. 9, inside the casing 13, 7
J, magnetic valve S, heating device 11, nozzle device? A water supply pipe W is installed between various equipment for supplying and heating water such as lZ 15, etc. for supplying and heating the water, and a heating device H is used to heat the cleaning water, keep it warm, and open a solenoid valve S. The casing 1 has a built-in control device E that commands and controls the closing.
By operating various switches on the operation panel 13a provided on the side of 3, washing water is jetted out to wash the private parts. Next, as shown in FIGS. 4 and 5, the nozzle device 15 is slidably attached to the cylinder 16.
and a nozzle body 1 inserted so as to be retractable in the axial direction thereof.
7, as shown in FIG. 3, the casing 1
The nozzle body 17 is attached to the casing 13 with the tip of the nozzle body 17 facing the opening side of the nozzle 1 through the support plate 18 in an inclined state. The cylinder 16 has a water inlet 1 at its upper end.
9, and this water inlet 19 is connected to the heating device H via a connecting pipe 38, an electromagnetic switching valve 30, a water supply pipe W, etc., which will be described later. Further, as shown in FIG. 4, the nozzle body 17 has a piston 20 on the head that slides inside the cylinder 16.
A nozzle head 22 is attached to the tip protruding from the cylinder 16 in a flow path 21 that communicates with the piston 20, and is pressed by a compression spring 23 inserted between the cylinder 16 and the nozzle head 22, which is normally not in use. The nozzle head 22 is stored inside the cylinder. Since the nozzle device 15 is configured as described above, when cleaning water flows into the cylinder 16 from the water inlet 19, the piston 20 receives the water pressure and the nozzle body 17 is pushed out from the cylinder 16. That is, the nozzle body 17 is pushed out to the optimal position for private part cleaning using the water pressure of the washing water, and after the supply of washing water is cut off, the nozzle main body 17 is pushed out by the urging force of the compression spring 23 as the water pressure decreases. 17 is returned to its original position. Note that a small-diameter spout 24 is opened at the tip of the nozzle head 22 for spouting cleansing water in an amount suitable for private part cleansing. Next, as shown in FIG. 5, the electromagnetic switching valve 30 described above is composed of a drive section 31 and a valve section 32, and the drive section 31 includes a plunger a and a coil b that applies an electromagnetic force to the plunger a. The valve part 32 has an on-off valve d that opens and closes a valve port d attached to and housed in a plunger a, and is provided with a water supply port and an inflow hole f for cleaning water, so that the drive part 31 has a watertight structure. It is fixed in place. Also, valve part 3
At the top of 2, there is a bifurcated water distribution pipe 3 that divides and feeds cleaning water into a nozzle device 15 and a self-cleaning nozzle 33, which will be described next.
4 is installed in such a manner that the pipe g communicating with the self-cleaning nozzle 33 can be opened and closed by the on-off valve d. The electromagnetic switching valve 30 is connected to the cylinder 16 as shown in FIG.
The nozzle device ts is attached to the nozzle device ts by screwing the support piece 34a protruding to the outside and holding it with the semicircular receiving piece 34b. A self-cleaning nozzle 33 is installed in one of the pipes g of the water distribution pipe 34 as shown in FIG.
This nozzle 33 is provided as a synthetic resin tube or a rectangular cylinder, and one end is attached to the end of the pipe g, and the other end is connected to the nozzle body 17 along the cylinder 16. It extends to the tip, and at the tip, as shown in Figure 7,
A latching piece 3 is installed at a position perpendicular to the axial direction of the nozzle body 17.
5 is horizontally protruding, and a locking protrusion 36 provided on the periphery of the tip of the cylinder 16 is removably penetrated into the engagement hole of the locking piece 35 to lock the self-cleaning nozzle 34 at its tip. The cleaning water discharge port 37 can be attached to the periphery of the upper end of the nozzle head 22 at a position where cleaning water can be sprayed. The other pipe line of the water distribution pipe 34 communicates with the water inlet 19 of the cylinder 16 through a connecting pipe 38. Note that the heating device H is fully energized, for example, only when jetting cleaning water, and at other times, enough power is supplied to keep the hot water in the heating device ffH warm. Next, the operation will be explained. When cleaning water is not being supplied to the cylinder 16, the nozzle body 17 is recessed into the cylinder 16, leaving the nozzle head 22 as shown in FIG. Here, if you want to clean your private parts, press the cleaning switch (not shown) attached to the operation panel 13a, and as shown in FIG. The device H1 electric Iff switching valve 30 is operated (see S, 30 in FIG. 10). As a result, the washing water is fed to the sanitary washing device 11, heated by the heating device H to a temperature suitable for private part washing, and fed through the water supply pipe W to the water supply port e of the electromagnetic switching valve 30. . At this time, when the electromagnetic switching valve 30 is energized, the brush jar a descends and closes the valve port C, as shown in FIG. It flows into the self-cleaning nozzle 33 from the hole f in the direction of the arrow shown in FIG. (30 in Figure 10)
), the periphery of the jet nozzle 24 of the nozzle head 22 is cleaned. When cleaning the rad 22 to the nozzle, a part of the cleaning water flowing into the valve part 32 flows from the inflow hole f through the other pipe path of the water distribution pipe 34 into the nozzle device 15, but the amount of the inflow is very small. Since the amount of water is small (most of it flows toward the self-cleaning nozzle 33 through the opening of the pipe g), water pressure sufficient to move the piston 20 cannot be obtained, and the nozzle body 17 does not extend from the cylinder 16 (see 15 in Fig. 10). , when the cleaning of the nozzle head 22 by the self-cleaning nozzle 33 is completed, FIG.
), the energization of the electromagnetic switching valve 30 is cut off by the command '' from the control word WIB (see 30 in FIG. 10), and the sixth
Open valve port C as shown. With the opening of the valve port C, the conduit g of the self-cleaning nozzle 33 is closed, and the cleaning water flowing into the valve portion 32 flows in the direction of the arrow in FIG. 2 into the cylinder from the water inlet 19
．． It flows in quickly. As a result, the water pressure inside the cylinder increases rapidly, causing the nozzle body 17 to extend to the position shown by the two-dot chain line in FIG. (see 15 in FIG. 1O), at which time the solenoid valve S and the heating device H continue to operate. To finish cleaning the private parts, press the stop switch on the operation panel 13a and close the solenoid valve S according to a command from the control device E (Fig. 9(B)), and conversely close the solenoid valve 30 (Fig. 9(C)). )) again (see S, 30 of the 10th session). As a result, the heating device H is no longer fully energized and enters a heat-retaining state (dotted line in FIG. When the force 23 overcomes the water pressure, the nozzle body 17 is retracted into the cylinder 16 by the compression spring 23. At this time, the cleaning water remaining in the nozzle device 15 flows back inside the cylinder 16 as the nozzle body 17 is immersed in the cylinder 16, and is discharged through the water inlet 19 connection pipe 38, water distribution pipe 34, and self-cleaning nozzle 33. It is discharged from the outlet 37 into the toilet bowl 12. Then, when the nozzle body 17 is immersed into the cylinder 16 leaving the nozzle head 22 behind, the solenoid valve S is opened again as shown in FIG. As in the initial stage of cleaning, the nozzle head 22 can be kept clean after private cleaning by feeding it to the self-cleaning nozzle 33 and discharging it from the discharge port 37 to the nozzle head 22 to clean the nozzle head. Note that the amount of cleaning water discharged from the self-cleaning nozzle 33 only needs to be discharged to the nozzle for a time sufficient to cleanly clean the rad 22, and its setting is controlled by the control device. Further, as in the past, the nozzle device 15 and the self-cleaning nozzle 33 are also provided with a flow rate valve that adjusts the flow rate of the cleaning water spouted.

【Effect of the invention】

Since the present invention is configured as described above, it has the following effects. (1) The present invention includes a self-cleaning nozzle that cleans the nozzle head in front of a nozzle device that spouts cleansing water toward private parts, and connects the self-cleaning nozzle and the nozzle device with an electromagnetic switching valve to flow the cleansing water. The nozzle head of the nozzle device is always clean because the nozzle is configured so that the nozzle can be switched to the self-cleaning nozzle side before and after cleaning the private parts to clean the periphery of the nozzle head that sprays cleansing water toward the private parts for a predetermined period of time. This allows for hygienic and comfortable local cleaning. (2) After cleaning the private parts, when the nozzle body is immersed into the cylinder by the force of the compression spring, the cleaning fluid filling the nozzle device is quickly discharged into the toilet bowl using the self-cleaning nozzle side. As a result, the nozzle body can be quickly stored in the cylinder, and it is also possible to suppress the washing water from spewing out from the rad's spout to the nozzle, and to protect the user's clothes, etc. when storing the nozzle body. Never get wet. (3) Furthermore, when the nozzle body is immersed into the cylinder, the cleaning water inside the nozzle device is discharged from the discharge port of the self-cleaning nozzle in such a manner that it flows back and cleans the outer peripheral surface of the nozzle body. Not only can the nozzle body be kept sanitary, the nozzle device can be driven smoothly and well without foreign matter adhering to the outer periphery of the nozzle body and preventing the nozzle body from extending or retracting, and the remaining cleaning water can be effectively There are also benefits to using it. (4) Furthermore, since the electromagnetic switching valve and the self-cleaning nozzle are installed in the nozzle device without requiring any special space, the narrow space inside the casing can be used effectively.
