Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nozzle cylinder for a human body private parts cleaning device (hereinafter simply referred to as a cleaning device) in a toilet.

In recent years, the use value of the cleaning device has been recognized from the viewpoint of health and hygiene, and its popularity is steadily increasing.

Cleaning devices are used for cleaning the anus after defecation and for cleaning the genitals of women (for bidets), and devices equipped with two nozzles that can be used separately for the two types of purposes have already been considered. However, the structure is complicated, the space required for installation is large, the operation procedure is multilayered, and the production cost increases.

The present invention provides a nozzle cylinder for a cleaning device that can be used for the above two types of applications with a single nozzle cylinder, exhibit satisfactory and effective performance for each, and lead to downsizing and cost reduction. It is.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a wall of the toilet bowl body, and a cylinder 2 is screwed onto the wall 1 with packings 3 and 3' interposed therebetween by a cap screw 4 and a lock nut 5.

Reference numeral 6 denotes a base, to which a hot water supply pipe 7 is connected, and is screwed onto one end of the cylinder 2 with a positioning nut 8. 9 is a piston that is slidably disposed within the cylinder 2, and 10 is a stopper collar of the piston 9 that is firmly inserted into the cylinder 2. Reference numeral 11 denotes a hollow nozzle whose one side (the right side in the figure) is fixed to the piston 9 and supported near the cap screw 4, and above the nozzle 11, a return spring is stretched between the cap screw 4 and the piston 9. 1
2, the piston 9 and the nozzle 11 perform the same back-and-forth movement in the axial direction. Reference numeral 13 denotes a roller having a smaller diameter than the hole 11', which is installed near the hole 11' on the other side of the nozzle 11, and creates a slight gap in the axial direction between the stop pin 14 and the blind plug 15 press-fitted into the hole 11'. It will be placed in a maintained condition. Reference numeral 16 denotes a valve seat having a plurality of through holes 16a, which is press-fitted and fixed into the hole 11'' of the nozzle 11 on the appropriate right side of the stop pin 14, and is fixed to the hole 11'' of the nozzle 11.
A valve 18 is set at 6 and is urged toward the valve seat by a spring 17.

11d is a hot water spout (for the anus, hereinafter referred to as A), which is connected to the hole 1 on the other side of the nozzle 11.
An appropriate number of rollers are provided at positions facing the rollers 16 disposed in the nozzle 1', and directly below the jet nozzle 11a (180° offset) with respect to the axis of the nozzle 11.
An elliptical spout (for bidet use, hereinafter referred to as B use) is provided, the center of which is slanted appropriately. As is clear from the figures, especially FIG. 1, the anal spout 11
The bidet spout 11b and the bidet spout 11b have different cross-sectional shapes, so that they produce different water forces. As can be seen in FIG. 2, the inner wall of the nozzle hole 11' that comes into contact with the roller 13 is
An arcuate cut portion matching the outer diameter of the roller 13 is provided as indicated by d so that the rollers 13 and 3 are in close contact with each other and the jet port 11b is completely blocked by the outer edge thereof. The figure is 11 for B.
Although only part b is shown, it goes without saying that the part 11a for A is also provided with a cut-off part.

Reference numeral 19 denotes a guide rod, which is rotatably supported by the base 6 on the right side as viewed in FIG. It is loosely fitted into the vertical portion of the hole 9a. (See FIG. 3) Therefore, the piston 9 is synchronized with the rotation of the guide rod 19, and is allowed to slide back and forth on the rectangular portion 19a of the guide rod 19.

20 is a pinion gear made of resin, and a guide rod 19
is fixed to one right end of the base 6, placed in the recess 6a of the base 6, and covered with a closing plate 21. Reference numeral 22 denotes a rack made of a flexible resin material, one end 22a of which is provided with means for preventing the pinion gear 20 from coming off from the end, and meshes with the pinion gear 20, and the other end 22b is fixed to a stopper 23. . Reference numeral 24 denotes a push-pull cable, which is guided by a guide member 26 attached to the base 6 and moved back and forth as shown by the arrow in FIG. the piston 9, the guide rod 19,
The rack 22, push-pull cable 24 and roller 13 constitute a remote control means.

Most of the configuration of the embodiment of the present invention has been described above, and next, details of its operation, operating functions, and effects will be described.

When the fourth illustrated operating lever 25 is at the neutral point N, the water pump (not shown) does not operate, and when shifted to the A position, the pump, electromagnetic valve, etc.
When the water is turned on and in operation, the water in the water supply tank passes through the hot water tank and is heated to an appropriate temperature.The hot water supply pipe 7
It is fed to the chamber 2a of the cylinder 2 through the. Due to the feeding pressure, the piston 9 located on the right side in the figure
The state as shown in the figure shifts to the left, and the nozzle 11 also has its A spout 11a facing upward.
As seen in the figure, it protrudes in front of the cap screw 4. Approximately in synchronization with the movement of the piston 9, hot water pressure opens the valve 18 through the water passage hole 9a of the piston 9, and the hot water flows from the passage hole 16a of the valve seat 16 into the nozzle hole 11'. In this case, as shown in Figure 6,
The B jet hole 11b is blocked by the roller 13,
Hot water is spouted only from the other open spout hole 11a for A.

Next, another usage of B will be described. When the operating lever 25 is set to the B position from the N point in the same manner as described above, the pinion gear 20 is moved to the rack 22 as seen in FIG.
The transition causes the guide rod 19 to rotate, and the piston 9 and nozzle 11 to rotate half a turn (180°).
At the same time, the nozzle 11 is
protrudes, and as shown in FIG.
Hot water gushes out only from the inclined spout hole. The 180° rotation mode of the nozzle 11 is adjusted and maintained by the function of the stopper 23.

The nozzle cylinder of the cleaning device in the present invention is
Since it is configured and operates as described above, it is possible to quickly and satisfactorily differentiate between A and B by simply switching the operating lever, that is, by remote control, with one stroke of a single lever, and it is easy to handle and operate. This can contribute to downsizing and cost reduction.
