Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a human body private parts cleaning device used in a toilet.

Generally, this type of cleaning device is configured to perform anal cleaning after defecation (hereinafter referred to as "shower cleaning") and female genital cleaning (hereinafter referred to as "bidet cleaning").

In conventional cleaning devices of this kind, a small jet hole is bored at the front end of a nozzle that is extendable to the toilet wall. In many cases, the water was simply jetted out, and the structure was such that cleaning water was continuously sprayed onto private parts at a constant pressure. For this reason, it had the disadvantage of being too irritating when used by people with hemorrhoids or women who had just given birth.

In view of the above conventional drawbacks, the present invention has a configuration in which a new valve device is installed in the cleaning water supply line of the conventional cleaning device so that cleaning water is ejected from the nozzle tip in a pulsed manner, The purpose is to provide the user with a comfortable feeling of use, increase the cleaning effect, and produce a pine surge effect.

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

FIG. 1 is a plan view showing an embodiment of the present invention, and also illustrates a water supply means for introducing cleaning water to a passage within a nozzle. Reference numeral 1 in the drawing denotes a fixed frame, which is fixed to the toilet wall W by a nut 7 via another fixed frame 2, rubber intervening members 3, 4, washers 5, and nozzle guides 6.
A pulse motor M ₁ (not shown) capable of forward and reverse rotation is fixed to the lower surface of the fixed frame 1, and power is transmitted to another pulley 10 above via a pulley 8 and a belt 9. Since the pulley 10 is fixed to the end of the threaded rod 11, the threaded rod 11 rotates as the pulley 10 rotates, and the movable body 12 screwed therewith moves in the axial direction (a, It is configured to be able to move in the direction of the arrow a′ (hereinafter referred to as the front-back direction). In order to move smoothly in this axial direction, two guide rods 1 are fixed at both ends to the fixed frames 1 and 2.
The movable body 12 is guided by 1A and 11B.

A holding frame 15 for attaching a motor is fixed to the movable body 12, and a pulse motor is attached to the frame 15.
_M2 is held fixed. Shaft 16 of the motor _M2
A pulley 17 is fixed to, and power is transmitted to another pulley 19 via a belt 18. The pulley 1
Reference numeral 9 denotes an inner nozzle 20 installed so as to penetrate the movable body 12 (this nozzle is a nozzle provided inside the outer nozzle 22 that only reciprocates in the front-back direction with the movable body 12 and does not rotate). It has the function of rotating or pivoting a certain object) around its axis. The inner nozzle 20 has approximately the same length in the axial direction as the outer nozzle 22, has a passage 20a for circulation of cleaning water formed in its axial center, and has five small holes 203 bored in its front end. ing.

The cleaning water flow passage 20a communicates with the water guide pipe 27 via the passage in the movable body 12 and the nipple 24 for attaching the water guide pipe.
When pressure water (cleansing water) is supplied to 0a, the three elongated holes 221, 222,
When 223 and the small hole 203 match as shown, the holes 203, 221, 222, 22
3, the washing water is vigorously jetted out.

The water guide pipe 27 has one end connected to the nipple 24 and the other end connected to the upper part of the hot water tank 28. A heater 29 is provided in the tank 28.
is installed to heat the water in the tank 28. Water from a water supply tank 30 is supplied to the lower part of the tank 28 via an electromagnetic valve 31 and a pump 32. The electromagnetic valve 31 is provided to close the nozzles 20 and 22 so that the cleaning water does not fall and leak from the tips of the nozzles 20 and 22 when the apparatus is not in use.

In the middle of the cleaning water supply system from the hot water tank 28 to the cleaning water distribution passage 20a inside the inner nozzle 20, for example, at the position indicated by the two-dot chain line in FIG. Valve device V
is provided.

The valve device V is constructed as shown in FIGS. 2 to 4. In these figures, the reference numeral 41 is a housing in which a water inlet 41a, a water outlet 41b, and a recess 41c are formed (water inlet 41a, water outlet 4
1b is connected to a portion 27a near the tank 28 and a portion 27b near the nipple 24 of the water conveyance pump 27, respectively), and a rotor 42 having a circular cross section is rotatably rotatable around the axis O in the recess 41c. It is installed. The rotor 42 has holes 42a and 42b that are perpendicular to each other and communicate with each other, and a protruding end 42c is formed at a position opposite to the water inlet 41a. A pulley 43 is fixed to the tip 42c with a machine screw 44, and the reduced rotational force from the motor _M3 is transmitted to the pulley 43 via a belt 45 and another pulley 46. A plate 48 is fixed to the housing 41 with bolts 47, and the motor _M3 is fixed to this plate 48.

Next, we will discuss the effect. When a toilet user finishes defecating and wants to clean the shower, press the attached shower cleaning switch (not shown) and the motor _M1
rotates, and the rotation of the threaded rod 11 causes the movable body 12 to move forward (in the direction a) from the rearmost position by a "certain distance", and the inner and outer nozzles 20 and 22 are placed in the "shower cleaning position". The "certain distance" is determined by determining the seating position of the user. In this embodiment, the motor _M1 is a pulse motor, and can be automatically stopped after a certain rotation. Therefore, the movable body 12 can be stopped after traveling the certain distance. Further, the constant distance can be changed and set as appropriate by controlling the motor rotation speed.

When the shower is in the washing position (separately,
When another switch is pressed, the motor _M2 starts, the inner nozzle 20 rotates around its axis, and the five holes 203 are connected to the elongated holes 221 and 22.
Matches 2,223. Also the motor _M2
At the same time as the ON operation, the pump 32 starts operating, and at the same time the electromagnetic valve 31 also becomes open, and hot water is forced into the passage 20a in the inner nozzle 20, so the hole 2
03 is aligned with the elongated holes 221, 222, 223, hot water is vigorously jetted out (note that the elongated holes 221, 222, 223
222, 223 may be provided, and the number of matching holes may be changed manually or automatically).

After the motor _M2 rotates to a certain degree due to the action of the timer, it rotates in the opposite direction, and the motor _M1 also rotates in the opposite direction, so that the nozzles 20 and 22 return to the rearmost positions in FIG.

By the way, as mentioned above, the holes 203, 221, 2
Warm water, which is cleaning water, is jetted out from 22 and 223, and since the apparatus of this embodiment is equipped with a valve device V, the jetted hot water is in a pulsed manner.
In other words, as shown in Figure 5, the relationship between the hot water spout height h (vertical axis) and the time t (horizontal axis) is that after it spews for t ₁ hour, it does not spout for t ₂ , and then again for t ₁ hour. The gushing action is repeated, such as gushing out only a small amount of water.

This kind of repetition is done with motor M ₃
Because the rotor 42 rotates around the O axis due to the rotation of
(The ratio of the time when the motor is connected to the time when it is not connected can be arbitrarily changed by using a pulse motor as the motor.)

The motor _M3 may be turned on only when the user presses the cleaning switch, or only when it is desired to eject pulsed hot water.
A separate switch may be provided to turn it on. However, in the latter case, if you do not want the water to be pulsed, the water outlet 41b needs to communicate with the passage 20a and be in a completely open state, so a photo sensor or micro switch is separately provided and the water outlet 41b is always in a completely open state as shown in Fig. 3. It must be stopped in the open position.

When washing the bidet, when the user presses the bidet washing switch, the nozzle 2 will move a certain distance (specifically about 4 cm) beyond the shower washing position.
0 and 22 move forward to the "bidet cleaning position", and the subsequent action is the same as in the case of shower cleaning.

The valve device V in the above embodiment has a rotor 4
This is based on a so-called rotary valve that opens and closes by rotating the valve 2 around its axis, but it is not limited to such a valve structure. For example, an on-off valve, that is, a type in which a flat plate member opens and closes a passage It may be something that is done continuously.

In this way, the present invention provides a nozzle in which a spout hole is formed at the tip and the tip is located inside the toilet bowl when in use, a tank for storing wash water, a water outlet 41b communicating with the nozzle, and a nozzle communicating with the tank. A valve device includes a housing 41 in which a water inlet 41a is formed, a valve member 42 that connects and shuts off communication between the water outlet 41b and the water inlet 41a at a predetermined period; It is characterized by having a supply means 32 for supplying water to the water inlet 41a. Therefore, the cleaning water from the front end of the nozzle is ejected in a pulsed manner, giving the user a more comfortable feeling than ever before, improving the cleaning effect, and at the same time producing a pine surge effect. This makes it extremely useful, especially for people with hemorrhoids and women who have just given birth.
