Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to an improvement in a sanitary washing device for washing private parts with warm water after using the toilet. Conventional devices of this kind (Japanese Patent Laid-Open No. 57-9
3608) will be explained with reference to FIG. Reference numeral 1 denotes a cylindrical cylinder, the tip of which is fixed to a nozzle guide 2, and the rear end of which is fixed to a base 4 having a hot water supply port 3. 5
is a seal ring. 6 is a nozzle pipe slidably inserted into the cylinder 1; its 7 flange-shaped base 7;
A spring 8 is provided between the nozzle guide 2 and the nozzle guide 2, and is biased by the spring 8 to be pushed into the inside of the cylinder 1. 9 is a nozzle hole provided upward at the tip of the nozzle vibro.

Next, its effect will be explained. When hot water is supplied from the hot water supply port 3, the nozzle vibro is pushed forward by the water pressure of the hot water. Hot water is ejected from the nozzle hole 9 and flows out through the gap 10 between the flange-like base 7 and the cylinder 1 and the gap 11 between the nozzle guide 2 and the nozzle vibrator 6, cleaning the surface of the nozzle vibro. . When the nozzle vibro is further pushed out and the 7 flange-shaped base 7 comes into contact with the rear end 12 of the nozzle guide 2, the nozzle vibro stops advancing.
The leakage of hot water from the gaps 10 and 11 is eliminated, and the full pressure of the hot water is inside the nozzle vibro, and the hot water is vigorously jetted out from the nozzle hole 9 to cleanse the private parts. The nozzle vibro is pushed into the cylinder 1 by a spring 8.

By the way, the conventional sanitary cleaning device having the above-mentioned structure and function has problems that require improvement as described below.

(1) The hot water supply port 3 is connected to the hot water supply tank by a hose, and when hot water is supplied to the cylinder 1, the cold water remaining in the hose and the cylinder 1 initially spouts out. Cold water washing is not only unpleasant but also harmful in winter. (2) Since the jetting direction of the nozzle hole 9 is unidirectional, the jetting of hot water is constant in one direction, and the human body must be moved so that the private parts of the human body coincide with that position. Furthermore, in order to improve the cleaning effect and the feeling of cleaning, it is necessary to move the human body, and these movements are complicated. An object of the present invention is to provide a sanitary cleaning device that solves this problem.

[Structure of the Invention] The sanitary cleaning device of the present invention includes a spring provided between the nozzle guide and the inside of a cylindrical cylinder whose front end is fixed to a nozzle guide and whose rear end is fixed to a base having a hot water supply port. A nozzle pipe that is biased to be pushed into the cylinder is slidably provided, and has a first injection hole and a second injection port at the tip of the nozzle pipe,
0 or less, characterized in that a nozzle piece is attached to which a movable valve is slidably provided, which is biased by a spring so as to close one of the first and second jet ports and open the other. The embodiment will be explained with reference to FIGS. 1 and 3. 1 to 1 excluding nozzle hole 9 in FIG.
2 has no difference from the conventional structure shown in FIG. 2, so its explanation will be omitted. The present invention is characterized in that a nozzle piece 13 is attached to the tip of the nozzle guide 6. The nozzle piece 13 has a first spout 14 at the rear and a second spout 15 at the front, and a movable valve 17 urged rearward by a spring 16 is slidably inserted inside. . 18 is a through hole of the moving valve 17. The first spout 14 and the second spout 1
5 has one or both of them inclined so that the jetted water concentrates at one point.0 movement valve 17 has the first spout 14 and the second spout 14;
The length is equal to the interval between the jet ports 15, and when one of them is closed, the other is opened. This nozzle piece 13
Prepare several different types of nozzle pieces 13,
If they are replaced and used, cleaning can be performed that is suitable for the user and the environment.

Next, its effect will be explained. FIG. 1 shows the state before the start of cleaning, and FIG. 3(a) is an enlarged view of the main part of FIG. 1. When hot water is supplied from the hot water supply port 3, the hot water advances inside the nozzle vibro, but does not jet out because the first jet hole 14 is closed by the expansion valve 17. Therefore cylinder 1
The remaining water inside and the inflowing hot water are discharged through the gap 10.11, and the tip of the nozzle vibro and the nozzle piece 1 are discharged through the gap 10.11.
30 Clean the surface. Also, the water in the cavity 19 at the tip of the nozzle piece 13 passes through the passage hole 18 of the transfer valve 170 into the cavity 1.
The hot water is ejected from the second spout 15 due to the water pressure of the hot water entering the interior of the hot water. However, this jet does not reach the cleaning position because the water pressure is low. FIG. 3(a) shows this state.

In this way, the cold water remaining in the cylinder 1 and the nozzle vibro, as well as the cold water initially flowing in, are discharged without reaching the cleaning position.

As the hot water supply from the hot water supply port 3 progresses, the nozzle vibro is pushed forward by the water pressure, and stops when its 7 flange-shaped base 7 comes into contact with the rear end 12 of the nozzle guide 2. At the same time, the outflow of hot water from the gap 10.11 is also stopped, so the water pressure inside the cylinder 1 increases, and the movable valve 17 is pushed forward against the spring 16, opening the first spout 14 and opening the second spout 14.
Close the spout 15. Therefore, the cleaning warm water is vigorously jetted out from the first jetting port 14. FIG. 3(b) shows the state at this time. When hot water is spouted from the first spout 14 for a certain period of time, the water pressure behind the movable valve 17 decreases, and the movable valve 17 is pushed backward by the spring 16 and the first spout 14
is closed, and the second spout 15 is opened. Therefore, the hot water in the cavity 19 and the hot water flowing into the cavity 19 from the through hole 18 are vigorously jetted out from the second spout 15. FIG. 309 shows the state at this time. When cleaning water is ejected from the second spout 15 for a certain period of time, the water pressure in the empty chamber 19 decreases, and the movable valve 1
The water pressure behind No. 7 becomes high again, and the moving valve 17 moves to No. 3 again.
It is returned to the position shown in figure (b). And during this time, there were 19 vacant rooms.
Hot water is supplied into the interior through a through hole 18. The above operation is repeated, and the first jet port 14 and the second jet port 15 alternately jet hot water to cleanse the private parts.

[Effects of the Invention] Since the sanitary washing device of the present invention has the structure and function described above, there is no jetting of cold water in the washing water at the beginning of use, and pleasant washing with warm water can be performed from the beginning. Since the cleaning is performed by hot water alternately spouted from the first spout 14 and the second spout 15 in different jet directions, the cleaning is more efficient than the conventional unidirectional spout 9 shown in FIG. It has a number of excellent effects, such as being able to more effectively adapt to the user/person and environment by preparing several types of nozzle pieces 13.
