Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a cleaning device for cleaning a part to be cleaned with cleaning water.

Structure of a conventional example and its problems A conventional cleaning device of this type will be explained based on the drawings. There is a toilet seat 2 on top of the toilet bowl 1, and 3 is a human body sitting on this toilet seat 2. Reference numeral 4 designates a toilet lid that is provided to be openable and closable; 5, a cleaning device body that houses the cleaning device; and 6, a cleaning nozzle that is attached to the cleaning device body and protrudes into the toilet bowl 1. Second
A structural diagram of this cleaning nozzle 6 is shown in the figure. Reference numeral 7 designates a washing water input port, 8 a washing water output port, 9 and 10 adhesion walls, and 11 and 12 feedback channels.

In such a configuration, when the cleaning water adheres to the adhesion wall 9 and starts to jet out in the direction of the arrow A, the cleaning water flows into the feedback flow path 11 and applies pressure from the side to the cleaning water jetting out in the direction of the arrow A. The flowing cleaning water is pushed toward the adhesion wall 10 side. Therefore, the cleaning water is ejected in the direction of arrow B. When the cleaning water starts to be spouted in the direction of the arrow B, the cleaning water flows into the feedback flow path 12, and pressure is applied from the side to the cleaning water jetting out in the direction of the arrow B, thereby forcing the flushing water toward the adhesion wall 9. In this way, the cleaning water oscillates between the arrow A side and the arrow B side with a certain period. Therefore, the first
As shown in the figure, cleaning is performed by moving the cleaning water in an oscillating manner along the concave direction of the part to be cleaned.

Although such a cleaning device can also clean the surrounding private parts, it is not suitable for intensively cleaning the private parts.

OBJECTS OF THE INVENTION In order to solve the above-mentioned conventional problems, it is an object of the present invention to make it possible to easily perform fluctuation cleaning and direct cleaning as needed.

Composition of the Invention A cleaning device according to the present invention includes a nozzle pipe that spouts cleaning water, a feedback type fluid oscillation element in the nozzle pipe, and a constriction part upstream of the feedback type fluid oscillation element in the nozzle pipe. When the water pressure in the nozzle pipe is low, the aperture of the constricted portion is narrower than the gap between the adhesion walls of the feedback type fluid oscillation element, and when the water pressure is high, the opening changes so that it becomes approximately the same as the gap between the adhesion walls. With this structure, you can select between fluctuation cleaning and direct cleaning by changing the water pressure.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described based on the drawings.
FIG. 3 is a structural diagram of the cleaning device. Items that are the same as before are given the same numbers. Reference numeral 13 denotes a constriction section provided upstream of the feedback type liquid oscillation element. The opening degree of the throttle part 13 changes depending on the water pressure, that is, the flow rate, and the opening b of the throttle part 13 when the water pressure is low is narrower than the gap a between the adhesion walls 9 and 10 of the feedback type liquid oscillation element. ing. In such a state, the cleaning water adheres to either of the adhesion walls 9, 10 and is ejected. For example, it is attached to the attached wall 9 and the arrow A
When the cleaning water starts to spout to the side, the cleaning water flows in the feedback flow path 11 in the opposite direction to the jetting direction, and flows through the input port 7.
Push the washing water spouting in the direction of arrow A from the side. Then, the cleaning water is pushed toward the adhering wall 10,
Therefore, the cleaning water is ejected in the direction of arrow B. The cleaning water that started to spout in the direction of arrow B will return to arrow A in the same way as above.
Squirt on the side. In this way, the cleaning water oscillates between the arrow A side and the arrow B side with a certain period. In other words, fluctuation cleaning can be performed. On the other hand, when the water pressure is increased, the opening degree of the throttle part 13 increases,
When the opening b of the constriction part 13 becomes approximately the same as the gap a between the adhesion walls 9 and 10 of the feedback type liquid oscillation element, the cleaning water is no longer influenced by the feedback type liquid oscillation element and direct cleaning is performed. This is the fourth
This will be explained with reference to FIG. 6. When the water pressure knob is between weak and about 5, that is, in the range shown in Fig. 4, the aperture b of the constriction part is narrower than the gap a between the adhesion walls 9 and 10 of the feedback type liquid oscillation element, so as shown in Fig. 5. Perform fluctuation cleaning between B and C. On the other hand, when the water pressure knob is set larger than 5, the aperture b of the constriction part in the range shown in Fig. 4 is approximately equal to the gap a between the adhesion walls 9 and 10 of the feedback type liquid oscillation element, and direct cleaning is performed as shown in Fig. 6. . In this way, when the water pressure is low, fluctuation cleaning is performed, and when the water pressure exceeds a certain level, direct cleaning is performed, so when you turn the water pressure knob to clean the area to be cleaned, the entire area to be cleaned will be washed in the initial stage. After washing, a relatively strong jet stream is used to intensively clean the local area, allowing for effective cleaning.

Effects of the Invention As described above, the cleaning device according to the present invention can arbitrarily select between fluctuation cleaning and direct cleaning by simply changing the water pressure, and can clean the area to be cleaned with a small amount of water. Effective cleaning can be performed without the need to move the human body in line with the nozzle.
