Description

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

The present invention relates to a cleaning nozzle for discharging cleansing water in a private part cleaning device for cleaning the anal area after defecating, or cleaning the female private parts during errands or menstruation.

[Conventional technology]

Private parts cleaning equipment cleans private parts by spraying warm water from a cleaning nozzle and hitting the private parts.
What is sprayed at this time is a steady flow of cleaning water, which does not give the user a pleasant stimulation sensation. For this purpose, there are devices that allow you to change the amount of water sprayed out per unit time, but this only changes the strength of the water flow that hits the local area, and the irritation does not change regardless of the strength of the water flow. It is at a low level. However, Japanese Patent Publication No. 58-13688 discloses a method in which air bubbles are included in the cleaning water jetted from a nozzle. When you apply cleansing water containing bubbles to your private parts, you can get a pleasant sensation of stimulation caused by the bursting of the bubbles contained in the cleansing water, but what is shown here is the amount of cleansing water required for cleaning. Since the cleaning water contained air bubbles in order to reduce
The mixing ratio of wash water and air was always constant. However, if the mixing ratio of cleaning water and air bubbles could be changed, it would be extremely desirable because it would be possible to adjust the level of stimulation that feels comfortable, which varies from person to person. For this reason, private parts cleaning devices have been developed that contain air bubbles in the cleaning water in order to provide a pleasant sensation of stimulation.

[Problem to be solved by the invention]

Here, the cleaning nozzle that sprays cleaning water has a telescopic shape that can be expanded and contracted so that the evacuation space can be reduced. A new problem arises. That is, as shown in FIG. 11, the telescopic cleaning nozzle is formed of a cylinder 53 and a slider 54 that is slidable with respect to the cylinder 53, and the cleaning water flowing from the cylinder 53 is sprayed at the tip of the slider 54. Although it will be injected from the outlet 55, if the cleaning water and air are mixed before entering the cylinder 53, the inner diameter of the cylinder 53 will be larger than the diameter of the pipe leading to the cleaning nozzle. Therefore, when the water flows into the cylinder 53, it separates into a gas layer and a liquid layer.For this reason, when the injection of cleaning water is started, the cleaning water with very few air bubbles is initially jetted out, and it remains for a while. When the air layer and the liquid layer are balanced, cleaning water mixed with a predetermined amount of air bubbles is ejected. Also, sometimes, as shown in FIG. 11(a), only the cleaning water is released until the gas-liquid interface reaches a certain height, and the air pressure inside the cylinder 53 increases, pushing the gas-liquid interface downward. As shown in FIG. 6(b), the action of air leaving all at once and raising the gas-liquid interface may be repeated, leading to a situation where the mixing ratio of air bubbles remains unstable no matter how long it lasts. This is more likely to occur if the cleaning nozzle is a three-stage telescopic type, and it is not possible to perform comfortable cleaning with such cleaning water having an unstable bubble mixing ratio. The present invention has been developed in view of these points, and its purpose is to stably eject cleansing water with a required bubble mixture ratio, and to provide local cleansing with a pleasant and stimulating sensation. The purpose of the present invention is to provide a cleaning nozzle for a private area cleaning device that can obtain the following effects.

[Means to solve the problem]

Therefore, the private parts cleaning device according to the present invention is a cleaning nozzle of the private parts cleaning device, which is equipped with an aeration means that mixes air into the cleaning water sprayed toward the private parts to contain air bubbles.
The cleaning nozzle is telescopically formed, consisting of a cylinder and a pipe-shaped slider that has a spout at the tip and is slidable relative to the cylinder. It is characterized in that it is provided with a nozzle that ejects a jet of cleaning water over the entire length of the cylinder toward one end. <Function> According to the present invention, the cleaning water that has flowed into the cylinder is sent into the slider before being separated into a gas layer and a liquid layer and is ejected from the spout at the tip of the slider.
For this reason, cleaning water with a stable bubble mixing ratio can be injected. <Embodiment> The present invention will be described below based on the illustrated embodiment. As shown in FIGS. It is equipped with a toilet seat 7 and a toilet seat cover 8 that are freely movable, and is configured to be able to be installed in place of the toilet seat cover and toilet seat of an existing seat-type toilet. As shown in FIG. 4, the cleaning device main body 1 includes a hot water tank 2 with a built-in heating means, a pump 3 for cleaning water, an air pump 4, and an anal cleaning nozzle 5 for spouting cleaning water.
1, a bidet cleaning nozzle 52, a solenoid valve 6, and an air pump 4 disposed between the hot water tank 2 and the solenoid valve 6, and the cleaning water sent to the cleaning nozzles 51 and 52 by the pump 3. An aspirator 7 is provided as an air mixing means for mixing the air. The solenoid valve 6 is for selectively sending the cleaning water mixed with air in the aspirator turf to both the nozzles 51 and 52, and as shown in FIG. Valve 6 which is exclusively opened and closed by
3.64. As shown in FIG. 7, the aspirator 7, which is an air mixing means, is provided with a nozzle portion 73 with a narrowed cross-sectional area in a linear flow path between the inflow lower 1 and the outflow lower 2 for washing water. At the same time, the air inflow lower 4 is communicated with the nozzle portion 73, and the reduced pressure generated when the cleaning water passes through the nozzle portion 73 causes air to be sucked in and mixed into the cleaning water. This allows the use of an air pump 4 with a low output. In the figure, 75 is a check valve that prevents cleaning water from entering the air inflow lower 4 side. The circuit diagram shown in FIG. 8 is a control circuit constructed by a microcomputer, and the pump 3, air pump 4, or electromagnetic valve 6 is connected to a pump drive circuit 11, an air pump drive circuit 12, and an electromagnetic valve, respectively. In addition to being connected via the control circuit 13, the operation switch 14,
A toilet seat temperature detection circuit 15 and a hot water detection circuit 16 for detecting the water temperature in the hot water tank 2 are connected. As shown in FIG. 10, the above-mentioned operation switch 14 is
It consists of a switch 14a for selecting "butt", a switch 14b for selecting "bidet", strength selection switches 14c, 14d, and a stop switch 14e, and when the switch 14a for "butt" is pressed, Washing water is ejected from the washing nozzle 51, and when the "bidet" switch 14b is pressed, washing water is ejected from the washing nozzle 52. When the stop switch 14e is pressed, the supply of cleaning water to the cleaning nozzles 51, 52 is stopped. When the strength levels are switched by the strength switches 14c and 14d, the control circuit 10 adjusts the output of the air pump 3 to change the amount of air mixed with the cleaning water, which is assumed to be a constant water discharge amount regardless of the strength level. When set to 0 strong, the amount of air mixed is increased, and when set to weak, the amount of air mixed is decreased. When the air mixing ratio is adjusted in this way, the user can:
As shown in FIG. 12, although the intensity of the cleansing shower in which cleansing water containing bubbles is applied to private parts is felt as a function of the amount of water spouted, the sensation of stimulation is felt as a function of the amount of bubbles. Now, the cleaning nozzle 51 is made up of a cylinder 53 and a pipe-shaped slider 54 that is slidable with respect to the cylinder 53, as shown in FIG.
The slider 54, which is urged in the direction of entering into the cylinder 53 by a return spring 59, protrudes from the other end of the cylinder 53 by the pressure of the cleaning water flowing in from one end of the cylinder 53. Indicates the condition. A spout 55 for jetting cleaning water is provided at the tip of the slider 54. In this cleaning nozzle 51, as described above, the cylinder 5
Cleaning water flows in from one end of the cylinder 53, and this inflow portion is provided with a nozzle 56 that jets the cleaning water as a jet into the cylinder 53. When the cleaning water mixed with air is supplied to the cleaning nozzle 51, the nozzle 56 jets the cleaning water as a jet toward the opening at one end of the slider 54, thereby causing the cleaning water mixed with air to flow into the cylinder 53. The air is fed into the slider 54 without being separated into an air layer and a liquid layer. In the figure, 58 is a slider 5 which is slidable along a guide shaft 80 and is operated by the pressure of cleaning water supplied to the cylinder 53.
This is a water stop bead that closes the opening of the slider 54 on the cylinder 53 side while the slider 4 is extended. On the other hand, as shown in FIG. 1(b), the cleaning nozzle 52 includes a cylinder 53 and a slider 54 that is slidable with respect to the cylinder 53.
a, and a slider 54b which is further slidable with respect to the slider 54a, and is formed as a three-stage telescopic structure, and the ejection port 55 is provided at the tip of the slider 54b. A nozzle 56 is provided in the cylinder 53, and a diaphragm 57 is provided at the opening of the slider 54a on the cylinder 53 side, so that a second jet is generated by the diaphragm 57 to obtain a finer air mixture state. ing. The water stop ball 58 is provided with a stirring blade 81 as shown in FIG.
It is even more effective to rotate the cleaning water so that a vortex of cleaning water is created at the inlet of the slider 54.

【Effect of the invention】

As described above, in the present invention, since the cleaning water that has flowed into the cylinder is sent out as a jet from the nozzle toward the slider, it enters the slider and exits the jet port before separating into the gas layer and the liquid layer. It is something that is ejected,
Therefore, cleaning water with a stable bubble mixing ratio can be injected, and the bubbles can also be made finer, so that the splashing of the cleaning water and the sound of bubbles popping can be reduced.
