Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a human body private part cleaning device, and more specifically, when cleaning water is sprayed from a nozzle toward a part to be cleaned. , relates to a human body private part cleaning device in which the nozzle makes minute reciprocating movements within a predetermined range.

(Prior art) As an example of such a human body private parts cleaning device,
There is one disclosed in No. 59-15141. Where,
The nozzle is extended to an operating reference point by a synchronous motor, and the nozzle reciprocates back and forth within a predetermined range around the reference point, so that cleaning water is sprayed toward the area to be cleaned.

(Problems to be Solved by the Invention) However, since the nozzle is driven by a synchronous motor, the moving speed of the nozzle is always constant. Since the front end and the rear end of the area to be cleaned are also the turning points of the nozzle, cleaning water is sprayed at these ends for a longer period of time than at other parts. Therefore, there was a problem in that the cleaning feeling was stronger and weaker at both ends and other parts of the area to be cleaned, respectively.

Therefore, the technical object of the present invention is to make the cleaning feeling uniform between both ends of the area to be cleaned and other parts so that there is no difference.

[Structure of the invention]

In order to solve the above technical problem, the technical means taken in the present invention is to control the rotation speed of the motor that drives the nozzle using a microcomputer.

(Operation) A series of signals sent from the microcomputer to the motor cause the motor to rotate, and the nozzle driven by the motor advances to the operating reference point, and then moves forward and backward within a predetermined range around the reference point. Cleaning water is sprayed onto the area to be cleaned from the nozzle that moves back and forth. Therefore, the speed near the turning point of the nozzle can be made higher than the speed at other parts, so the spraying time of cleaning water to both ends and other parts of the area to be cleaned can be shortened. Can be shortened. Therefore, the cleaning feeling can be made uniform in any part of the area to be cleaned, and the conventional problems can be solved.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings. 1 to 7, the support tube 11 fixed to the rear wall 10a of the toilet bowl 10 includes:
A nozzle 12 is slidably mounted. Therefore, there are five holes 12 on the upper side of the tip of the nozzle 12.
a, that is, an injection port is formed, and the nozzle 12
When the cleansing water is forced into the axial passage 12b, the cleansing water is sprayed from the spout 12a toward the area to be cleaned (anus or bidet). Thus, the axial passage 12 of the nozzle 12
Approximately the front half 14 of the sleeve 14 is located at the rear end opening of b.
a is fitted, and approximately the rear half 1 of the sleeve 14
4b is fitted into the front end opening 15a of the hose 15. The rear end opening 15b of the hose 15 is an outlet of a hot water tank 18 in which hot water heated by a heater 17 via a solenoid valve 16 and heated to a predetermined temperature by a thermosensor mechanism (not shown) is stored. 18a. A pump 20 is interposed between the inlet 18b of the hot water tank 18 and the water tank 19 in which room temperature water is stored, and at the same time when the pump 20 is activated and the solenoid valve 16 is opened, The room temperature water in 19 is connected to the inlet 1 of the hot water tank 18.
8b, and the water pressure causes the hot water tank 18
The hot water discharged from the discharge port 18a is force-fed to the axial passage 12b of the nozzle 12 via the solenoid valve 16, the hose 15, and the sleeve 14, and is injected from the spout 12a as cleaning water.

A groove 21a is formed in the plate 21 arranged on the rear side of the rear wall 10a of the toilet bowl 10 in the front-rear direction (left-right direction in the drawing). Fixed block 2
2 lower protrusions 22a are slidably fitted. Further, a stepping motor 23 is fixed to the lower rear side of the plate 21 with a screw, and after a shaft 23a of the motor 23 projects above the plate, a pulley 24 is fixed thereto. This pulley 24 is located on the rear side of the rear end portion 21b of the groove 21a. Furthermore, another pulley 25 is rotatably mounted on a shaft 26 fixed to the front end side of the plate 21.
The groove 21a is located further forward than the front end 21c of the groove 21a.

A belt 27 is disposed between the groove 24a of the pulley 24 and the groove 25a of the pulley 25, and the intermediate part of the belt 27 is connected to a block fixed to the rear end of the nozzle 12 by a member 28. It is designed to be fixed at 22. Since the shaft 23a of the stepping motor 23 can rotate in either the forward or reverse direction, by appropriately controlling the stepping motor 23, the nozzle 12 and the block 22 can be rotated in the front-back direction along the groove 21a. It is now possible to move it.

Here, the device 30 for controlling the stepping motor 23 for driving the nozzle 12 will be explained. The device 30 consists of a microcomputer 31 and a motor control means 32 under the control of the microcomputer 31. computer 3
1 includes therein a CPU 311, a control value storage means 312, and an external input/output control section 313. The external input/output control section 313 of the microcomputer 31 includes two switches SW1 and
SW2 is connected, and when you want to clean the anus, you only have to turn on switch SW1, and when you want to clean the bidet, you only have to turn on switch SW2, and the two switches SW1 and SW2 are connected. cannot be turned on at the same time.

Thus, the device 30 is designed to perform the following functions. (See Figures 5-6).

When the switch SW1 is turned on by a user (not shown) seated on the toilet seat (not shown) on the toilet bowl 10, the motor 23 rotates in the forward direction, and the movement of the belt 27 moves the nozzle 12 from the storage position to the storage position. It extends toward the operation reference point P which is Lcm away from the position. Also, what is the storage position of the nozzle?
Although not shown, this refers to a state in which the front end surface 12d of the nozzle 12 is flush with the front end surface 13a of the cap 13 of the support tube 11.

When the nozzle 12 reaches the operating reference point P, it temporarily stops, and at the same time the solenoid valve 16 opens, the pump 20 operates, and the water pumped into the hot water tank 18 by the pump 20 is pumped through the solenoid valve 16, the hose 15, and the sleeve 14. The liquid is fed under pressure to the axial passage 12b, and is injected from the ejection port 12a.

When water starts to be sprayed from the spout 12a, the motor 23 rotates in the forward direction at a rotational speed V1, and the nozzle 12 moves to the operating reference point P while spraying cleaning water.
The front gear shift point Q is located cm forward from the point Q.

When the nozzle 12 reaches the forward shift point Q, the motor 23 begins to rotate in the forward direction at a rotational speed V2 (>V1), and the nozzle 12 moves forward from the forward shift point Q by 1' cm while injecting cleaning water. The vehicle reaches forward turning point R.

When the nozzle 12 reaches the forward turning point R,
The nozzle 12 temporarily stops while spraying cleaning water.

The motor 23 begins to rotate in the opposite direction at a rotational speed V2, and the nozzle 12 retreats to the forward shift point Q while spraying cleaning water.

After the nozzle 12 has retreated to the forward shift point Q,
The motor 23 rotates in the opposite direction at a rotational speed V1, and the nozzle 12 passes through the operation reference point P while jetting cleaning water, and reaches the rear shift point Q' which is located cm behind the operation reference point P. .

When the nozzle 12 reaches the rear shift point Q', the motor 23 begins to rotate in the opposite direction at the rotational speed V2, and the nozzle 12 moves backward by cm from the rear shift point Q' while injecting cleaning water. It reaches the rear turning point R'.

When the nozzle 12 reaches the rear turning point R',
The nozzle 12 temporarily stops while spraying cleaning water.

Once the nozzle 12 stops at the backward turning point R', the motor 23 rotates in the forward direction at a rotational speed V.
2, the nozzle 12 reaches the rear shift point Q' while spraying cleaning water.

When the nozzle 12 reaches the rear shift point Q', the motor 23 begins to rotate in the forward direction at a rotational speed V1, and the nozzle 12 moves forward toward the operation reference point P while jetting cleaning water.

Reciprocating movement of the nozzle 12 in the front and back direction (P→Q→R
→Q→P→Q'→R'→Q'→P) is repeated 10 times, and then the switch SW1 is automatically turned off to stop spraying the cleaning water and the nozzle 12 is moved to the storage position. Ru.

When the switch SW2 is turned on, the operating reference point P position is just further forward than when the switch SW1 is turned on, and other things are the same.

To describe the operation of the above configuration, the switch
When SW1 is turned on, the nozzle 12 moves forward and is moved from the storage position to the operating reference point P.

When the nozzle 12 reaches the operating reference point P, the nozzle 1
2 temporarily stops, and the spout 1 of the nozzle 12
Cleaning water is now sprayed from 2a. The nozzle 12 reciprocates in the front and back direction centering on the operation reference point P while spraying cleaning water, but the moving speed of the nozzle 12 is different from the operation reference point P during forward movement (during backward movement). It is low between shift points Q and Q';
Since the distance between the shift points Q and Q' and the turning points R and R' is high, the amount of cleaning water sprayed onto the area to be cleaned can be made substantially uniform, and the cleaning feeling can be made uniform.

As shown in Fig. 7, when the nozzle 12 reaches the shift points Q and Q', the moving speed is not immediately set to V2, but the speed is gradually increased until the nozzle 12 reaches the turning points R and R'. It may be set to V2. Further, the motor is not limited to a stepping motor as long as the rotation can be controlled.

〔Effect of the invention〕

As described above, in the present invention, the microcomputer is used to control the motor that drives the nozzle, so that during the reciprocating movement of the nozzle within a predetermined range, the moving speed near the turning point of the nozzle is The cleaning time can be made uniform in all parts of the part to be cleaned by increasing the moving speed in each part, thereby making it possible to achieve a uniform cleaning feeling and to solve the conventional problems.
