DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a human body part, and more particularly to a nozzle for cleaning a human body part.

[0002]

2. Description of the Related Art In a human body part cleaning apparatus having a function of cleaning a human body part, a hot water is jetted toward a human body part from an ejection port provided at a tip of a cleaning nozzle to wash the human body part. Attempts have been made to ensure comfort during cleaning.

[0003] As a washing nozzle of this human body local washing apparatus, there is one disclosed in Japanese Utility Model Laid-Open No. 61-35984. In this conventional technique, a vertically movable valve body is housed inside the cleaning nozzle, and when the water force is equal to or higher than a set value, the valve head is moved upward by a pressure drop at the upper portion of the valve body due to the velocity head and a static pressure difference from the atmosphere side. Then, the valve body and the valve seat are brought into contact with each other so that the shape of the jetted water can be switched.

[0004]

When the cleaning nozzle of the above-mentioned conventional human body local cleaning apparatus is to be strongly cleaned at the time of use, the water amount is increased by increasing the amount of water, and the valve body rises and a plurality of valves are raised. By forming an ejection port having a small diameter, the ejection pressure is increased by reducing the ejection area, and strong washing can be performed. When weak washing is desired, the water force is reduced by reducing the amount of water, and the valve body descends to increase the ejection area to lower the ejection pressure, thereby enabling weak washing.

[0005] In this case, when it is desired to perform strong cleaning, the number of ejection ports increases, so that the resistance between the cleaning water and the housing and valve body of the cleaning nozzle increases, and a desired cleaning power cannot be obtained. Also, if you want to wash weakly, the valve will descend,
At this time, since the ejection area suddenly increases with a slight drop, the ejection pressure also sharply decreases. When the valve body descends, the number of the ejection ports becomes one, and the ejection pressure also decreases. Therefore, the washing power for weak washing is not sufficient.

In addition, the conventional cleaning nozzle has a large number of parts and a complicated structure, so that a large cost is required for manufacturing.

Therefore, according to the present invention, sufficient washing power can be obtained both when strong washing is desired and when weak washing is desired, a sudden change in ejection pressure is prevented, and the number of parts is small and the structure is simple. It is a technical task to enable the production at low cost.

Configuration of the Invention

[0009]

SUMMARY OF THE INVENTION A water supply source, a cleaning nozzle connected to the water supply source, a flow control device disposed between the water supply source and the cleaning nozzle for adjusting a flow rate to the cleaning nozzle, and a water supply source A washing nozzle of a human body local cleaning device having a water shutoff valve disposed between the water flow control device and a water stop valve for stopping the flow of the cleaning water from the water supply source, the cleaning water being provided at the tip of the cleaning nozzle and directed toward the human body local portion. A first jet port provided at the center of the jet port for jetting water, a second jet port provided around the first jet port, and the inside of the cleaning nozzle divided into a jet port side and a water supply source side. And a convex portion that forms an orifice in the elastic member or the housing of the cleaning nozzle so as to separate the first and second jet ports from each other.

[0010]

The technical means described above operates as follows. The flow rate of the cleaning water flowing from the water supply source is controlled by the flow control device. When the flow rate of the washing water flowing into the washing nozzle is small, the pressure difference between the washing water at the front (spout port side) and the rear (water supply source side) of the elastic member is small, and the elastic member is not deformed. The washing water is jetted from both the jet port and the second jet port, and a jet having a widespread and weak water is supplied. Further, as the flow rate of the washing water flowing into the washing nozzle increases, the pressure difference between the front part and the rear part of the elastic member gradually increases. As the pressure difference increases, the orifice formed between the elastic member and the housing of the cleaning nozzle becomes narrower, and finally the orifice closes. Then, the communication between the first jet port and the second jet port is cut off, and the washing water is no longer jetted from the second jet port, and the jet area becomes small, so that the pressure of the washing water in the cleaning nozzle increases. In addition, the washing water ejected from the first ejection port is supplied with a jet having a small spread and a strong water force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

Since the present invention can be used for both the anal cleaning nozzle and the bidet cleaning nozzle, the anal cleaning nozzle and the bidet cleaning nozzle are unified, and the cleaning nozzle 3 will be described below.

As shown in FIG. 1, a cleaning nozzle 3 is connected to a water supply source 1 via a pipe 2. On the pipe 2, a water stop valve 4, a solenoid valve 5,
A hot water tank 6 is provided. The control device 7 is connected to the water stop valve 4 and the solenoid valve 5, respectively, controls opening and closing of the valve and the solenoid valve, and controls a thermo sensor (not shown) provided in the hot water tank 6. Energization is controlled.

In this configuration, when an operation switch (not shown) is turned on when the user uses the control device, the control device 7 is operated to open the water stop valve 4 and the solenoid valve 5, and the washing water is supplied. The water is discharged from the water source 1 and spouted from the washing nozzle 3 toward the local body part.

FIG. 2 is a view of the cleaning nozzle 3 as viewed from the upper part (jet hole) of the tip. An ejection hole provided at the distal end of the housing 3a of the washing nozzle 3 for ejecting washing water toward a human body local part is provided with a first ejection hole portion 10 provided at a central portion.
And a second ejection hole 11 provided around the first ejection hole 10.

FIG. 3 shows a vertical cross section of the tip of the cleaning nozzle 3. The elastic member 20 is fixed to the inner surface of the housing 3a of the cleaning nozzle 3 by being pushed by the mounting member 30, and the annular convex portion 20b forms an orifice 40 with the housing 3a of the cleaning nozzle 3. Mounting member 30
Is welded to a stepped hole 3b provided in the lower portion of the cleaning nozzle 3 while fixing the elastic member 20 to the inner surface of the housing 3a of the cleaning nozzle 3. The attachment member 30 is provided with a water passage hole 30a through which the washing water passes.

FIG. 4 shows the upper part of the elastic member 20 (on the side of the ejection port).
FIG. A water hole 21 through which washing water passes is provided at the center. Also, the first ejection hole 10 and the second ejection hole 1
An annular convex portion 22 forming an orifice 40 is provided between the annular convex portion 22.

An annular convex portion 22 for providing a gap between a and the annular convex portion 22 provided on the elastic member 20 is formed.

Next, the operation of the embodiment according to the present invention will be described. When the user turns on an operation switch (not shown), the control device 7 (FIG. 1) opens the water stop valve 4 and the washing water supplied from the water supply source 1 (FIG. 1) It flows in the direction of the arrow (FIG. 3). At this time, the flow rate of the washing water is adjusted by the user operating the flow rate adjusting button or knob (not shown) by himself / herself, and the controller controlling the opening and closing of the solenoid valve 5 (FIG. 1). Is done.

In FIG. 3, the flow rate of the washing water supplied from the water supply source 1 is adjusted by the solenoid valve 5 and flows in the direction of the arrow. At this time, if the flow rate of the washing water is small,
No deformation of the first jet port 10 and the second jet port 11
From this, a wide and weak water jet is obtained. As the flow rate of the washing water increases, the elastic member 20 is deformed, and the orifice 40 becomes narrow. Then, the pressure of the washing water ejected from the first ejection port 10 becomes high, and the pressure of the washing water ejected from the second ejection port 11 becomes low. Finally, the orifice 40 is closed and the pressure toward the second ejection port 11 is reduced. When the communication is cut off, the washing water is no longer ejected from the second ejection port 11, and the washing water is ejected only from the first ejection port 10, so that a jet with a small spread and a strong water force is obtained.

[0021]

As described above, the cleaning nozzle of the apparatus for cleaning a human body according to the present invention is provided with a spout at a central portion and a peripheral portion. And a jet having a sufficient detergency is obtained with a strong water force. Also, when you want to wash weakly, the washing water is spouted from all the spouts.
A shower-like jet is obtained, and sufficient detergency is obtained even when cleaning is performed weakly. In addition, when the flow rate decreases, the orifice opens little by little, so that there is no sudden pressure change, and the strength of the user's preference can be adjusted.
