2. Description of the Related Art Conventionally, in order to obtain an optimum amount of water for each individual, a method of suppressing power consumption of a heating device without mixing air into hot water introduced from a heating device (for example, a hot water tank) near a nozzle. Patent No. 1,185,100, "Local cleaning device" (Totohki Co., Ltd., November 15, 1979)
Date application). Further, as a cleaning method suitable for cleaning hemorrhoids and the like, as a cleaning method of Japanese Utility Model Publication No. 1-39824, "a human body local cleaning device" (Aisin Seiki Co., Ltd., March 1983)
There is application on the 31st of every month. In this case, the valve opening is suddenly changed by rotating the valve device instead of mixing air into the wash water.

[0003]

The water pressure most suitable for washing with warm water varies greatly among individuals, and even the same person changes depending on the purpose and physical condition. For example, when a person with constipation is irritated before stool to relieve congestion in the anus, it may be better to strengthen it. On the contrary, a person with hemorrhoids may be weaker. For this reason, the amount of water discharged can be adjusted in multiple steps from weak to strong, but in order to alleviate congestion, a method has been proposed in which, for example, a motor is used to periodically change the valve opening of the water amount adjusting valve device. . In this method, there is a great possibility that a water hammer will be caused by causing a sudden change in the water supply pressure in the direct water supply type. In addition, a method has been proposed in which air is mixed into warm water from the cleaning nozzle to reduce the power consumption of the heating device without lowering the cleaning effect, but in this method, the amount of air is uniquely determined by the amount of water. It is impossible to change the water pressure while keeping the water volume constant. The present invention provides a human body local cleaning apparatus capable of giving a water force and a cleaning pattern according to a user's purpose and preference by changing the air amount while keeping the water amount constant without causing a water hammer. It is a thing.

[0004]

According to the present invention, the other end of a ventilation valve, one end of which is open to the atmosphere, is connected and connected in the middle of a water passage extending from a water supply port to a discharge nozzle for washing water for human body part. The present invention relates to a human body local cleaning device capable of adjusting the ventilation amount of a ventilation valve.

In the present invention, in order to prevent a water hammer caused by a change in water amount, which is a conventional problem, the amount of bubbles mixed in the wash water is changed so that the amount of water is not changed. This allows the water force to change suddenly without changing the amount of water. Further, in order to give a water force and a cleaning pattern according to the purpose and preference of the user (for example, to increase or decrease the water force in a cycle of 1 to 2 seconds), the ventilation valve of the air conditioner is rotated by a DC motor, If the rotation direction, rotation speed, and timing of the DC motor are stored in advance in the microcomputer of the controller, the opening degree of the ventilation valve can be changed in a fixed sequence. As a result, the user can obtain, for example, a strong and weak water pressure pattern suitable for alleviating congestion. Further, if the operation panel section is provided with a variable resistor capable of controlling the rotation of the DC motor, the ventilation valve opening degree can be roughly set, so that the water force according to the taste can be obtained.

Reference numeral 12 is a controller incorporating a microcomputer, and 13 is an operation panel.

FIG. 2 is a cross-sectional view of the air conditioner 9, which has an ejector 9f with a narrow water passage, so that the air from the suction port 9a is introduced into the inlet 9 of the ventilation valve 9c.
It can be mixed into the cleaning water channel via b, the slit 9d, and the discharge port 9e. Since one end of the ventilation valve 9c is connected to the output shaft of the DC geared motor 9g (M2) by the shaft 9h, the communication opening degree of the slit 9d and the discharge port 9e can be changed as the motor 9g rotates left and right. It can also be closed. The rotation angle of the motor 9g is
Motor 9g is regulated by a stopper (not shown) provided at the maximum opening position and the closing position of slit 9d.
The approximate angle, that is, the opening of the slit 9d is determined by the drive current to the motor 9g depending on the rotation direction from the closed position, the drive time, and the drive speed.

FIG. 3 is an external view of the ventilation valve 9c, which has a substantially triangular slit 9d on its cylindrical outer circumference. In addition,
The vent valve may be of another type, such as a needle valve type or a ball valve type, depending on the desired air amount characteristics. FIG. 4 shows the operation panel 13, 14 is a stop switch and 15 is a wash water switch for closing and opening the solenoid valve 4, respectively. 16

At, the user presses the wash water switch 15 of the operation panel 13, but in FIG. 5, the wash water amount is set to be strong, and therefore the washing is started with the maximum water amount. When the massage switch 17 is pressed, the motor 9g starts periodical forward / reverse inversion in the operation sequence stored in advance in the microcomputer. When the massage switch 17 is pressed again with, the motor 9g rotates to a position where it closes the slit 9d, so that the massage switch stops. When the water amount reduction switch 19 is pressed once with, the water amount control valve is driven until the amount of water stored in the microcomputer is reached. When the air amount adjusting knob 16 is slowly turned to the right from the stop position, the motor 9g slowly rotates in the opening direction to gradually increase the opening degree of the slit 9d.
When the stop switch 14 is pressed with, the solenoid valve 4 closes,
The water discharge from the cleaning nozzle 11 is stopped. It should be noted that the operation panel, the air amount adjusting method and the cleaning water amount controlling method of the above-described embodiment are merely examples, and a method of manually rotating the shaft 9h to adjust the air amount or using a water amount sensor is not used. The system may be changed to another system such as controlling the water amount by combining a known water pressure regulator and a water amount control valve.

The operation of the human body local cleaning apparatus in the above embodiment will be described. In FIG. 1, tap water supplied from the branch faucet 2 is closed by a solenoid valve 4 when the human body part cleaning device 1 is not used. When the wash water switch 15 on the operation panel 13 of FIG. 4 is pressed, the electromagnetic valve 4 opens and tap water flows into the hot water tank 7 through the water amount control valve 5 and the water amount sensor 6. At this time, the valve opening of the water amount control valve 5 is controlled by the water amount signal from the water amount sensor 6 and the controller 12 so that the wash water amount arbitrarily set by the water amount increase switch 18 and the water amount decrease switch 19 of the operation panel 13 is held. The microcomputer compares and calculates the water amount data stored in advance in the microcomputer, and the water amount control valve 5 is driven. That is, the water amount control valve 5 is feedback-controlled according to the fluctuation of the water supply pressure, and the set water amount is maintained.

The water in the hot water tank 7 is heated to about 40 ° C. by the hot water heater, pushed out by the water supply pressure, and jetted vigorously from the ejector 9f of the air conditioner 9.
Air is sucked from the blow-in port 9a and mixed into the wash water, and is discharged from the wash nozzle 11 toward the human body part. Therefore, as compared with the wash water without air, the force with which the bubbles hit the local parts improves the washing power, and the feeling of washing can be stronger or weaker than the wash water without air, depending on the air mixing ratio. As a result, the amount of washing water can be reduced and the power consumption of the warm water heater can be suppressed. Further, when the massage switch 17 of FIG. 4 is pressed, the ventilation valve 9b is rotated left and right arbitrarily,
The amount of air can be changed cyclically as shown in FIG. 5 and the amount of air can be arbitrarily changed by the air amount adjusting knob 16.

[0012]

EFFECTS OF THE INVENTION According to the present invention, the amount of air can be arbitrarily changed, so that cleaning can be performed according to the user's purpose (anal washing, bidet washing, congestion relief, local irritation in the case of constipation, etc.) and taste. In addition, it is possible to make the detergency due to air inclusion an optimum value. Further, since the amount of washing water is small due to the inclusion of air, power consumption can be suppressed and the size of the hot water tank can be reduced. Furthermore, if the pattern of changes in the opening degree of the ventilation valve is stored in advance in a fixed sequence,
Compared to the conventional method of suddenly changing the amount of water, there is no risk of water hammer, and it is possible to wash comfortably.
