Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an injection position fine adjustment mechanism that can move the nozzle position relative to the user's private parts in accordance with the physique of the user, and a mechanism for finely adjusting the injection position at a set injection position. The present invention relates to a spray nozzle position drive control method for a sanitary cleaning device that is equipped with an oscillating cleaning mechanism that oscillates and can perform sanitary and comfortable cleaning.

[Conventional technology]

BACKGROUND ART Hitherto, sanitary cleaning devices for cleaning private parts of the human body have been used with various structures, such as those that enable anal cleaning or anal cleaning and bidet cleaning.

In general, a spray nozzle position drive control method for this type of sanitary washing device is such that, when in use, a nozzle appears at a structurally predetermined location for spraying cleansing water in the toilet bowl, and directs cleansing water from the nozzle toward the private parts to be cleaned. The nozzle is controlled so that it ejects and retreats to a predetermined storage position after use.

[Problem to be solved by the invention]

However, in the conventional structure, the exposed position of the nozzle is a pre-designed fixed position, so depending on the physique of the user, for example, adults and children have different local positions with respect to the toilet bowl, causing a deviation in the optimal position of the nozzle. However, when cleaning a private part, the user must move the buttocks by themselves while sitting on the toilet, which is extremely troublesome. there were.

The present invention was devised in view of the above problems, and includes a jetting position 'R1 adjustment mechanism that allows the position at which cleaning water is jetted to be adjusted according to the user's physique, and a jetting position that adjusts the jetting water to a predetermined position. It is an object of the present invention to provide a method for controlling the position of a spray nozzle in a sanitary cleaning device, which includes a swinging cleaning mechanism that swings within a range to clean the surrounding private parts.

[Means to solve the problem]

The injection nozzle position drive control method for a sanitary cleaning device according to the present invention includes slidingly pushing a nozzle rod inward against a nozzle cylinder, and moving the nozzle rod to a storage position and a cleaning position via a nozzle cylinder reciprocating drive means. The nozzle cylinder is slidably supported in the axial direction with respect to the support bracket, and an injection position fine adjustment mechanism is configured between the nozzle cylinder and the support bracket, and the nozzle cylinder reciprocating drive means and In a sanitary cleaning device in which an injection position a adjustment mechanism is manually or automatically driven via a central control circuit to finely adjust the position of an ejection hole of a protruding nozzle rod, the injection position fine adjustment mechanism has a predetermined fine adjustment width. and a swinging function that reciprocates with a predetermined amplitude around the adjustment position, and when the swing width exceeding the most extended position or the most retracted position of the adjustable range is set to the expected adjustment position,
The gist of the invention is to control the swinging drive so as to ensure a predetermined swinging width at a position inside the fine adjustment range as the limit.

[Effect]

Therefore, the nozzle cylinder reciprocating drive means that can further adjust the nozzle cylinder that accommodates the nozzle rod that moves forward and backward into and out of the anus cleaning position and the bidet cleaning position is finely adjusted within a predetermined range, and at the same time, the adjustment at the anus cleaning position is performed. When the adjustment position is to be oscillated by a predetermined width at a position, if the oscillation width exceeds the extreme end of the adjustable range, the predetermined width will be adjusted at a position inside the range with the fine adjustment width as the limit. Since the drive is controlled to ensure rocking, the cleaning amplitude is always ensured.

〔Example〕

An embodiment of the injection nozzle position drive control method for a sanitary cleaning device according to the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view showing the nozzle storage state, and FIG. 2 is a side view of the nozzle assembly. The side sectional view and FIG. 3 are also partially cutaway plan views of the nozzle assembly.

The nozzle assembly 1 is located at the center of a sanitary cleaning device main body 2 which is located behind the toilet seat placed on the top surface of the toilet and is fixed to the toilet. Sliding ribs 4, 4 are provided in a horizontal position to protrude along the nozzle cylinder 3, and the sliding ribs 4, 4 are provided in a horizontal position to guide grooves 6, 6 formed so that the nozzle cylinder 3 faces the support bracket 5. 4 is slidably fitted and held in a fine movement guide structure 7. A rack 8 constructed on the rear side wall of the lower surface of the nozzle cylinder 3 is connected to a drive shaft of a cylinder position fine adjustment drive control motor 9 such as a synchronous motor or a pulse motor fixed to one side of the support bracket 5. The attached pinion 10 is engaged. The cylinder position fine adjustment drive control motor 9, as shown in FIG.
It is connected to the central control circuit CPU through a motor driver DI, and drives the cylinder position fine adjustment drive control motor 9 in forward and reverse directions to move the nozzle cylinder 3 within a predetermined range (approximately 2.0 cm) in the direction of arrow A. It comprises an injection position fine adjustment mechanism 11 that is displaced and changes the support position.

Further, a temporary spring I4 having a fixed negative end is wound around a drum 13 which is mounted on a shaft of a temporary spring case 12 constructed at the rear end of the nozzle cylinder 3, and the outer end of the plate spring 14 is connected to the nozzle cylinder. The tip of the nozzle loft 15 is connected and fixed to the rear end of the nozzle loft 15 which is airtightly inserted through a sealing member.

The nozzle position change drive control motor 16, such as a synchronous motor or a pulse motor, which is fixedly installed on the side of the plate spring case 2, has the drum 13 attached to a drive shaft, and has a central control circuit CPU and a motor driver D2. The nozzle rod 15 is displaced (arrow B) relative to the nozzle cylinder 3 by unwinding the plate spring 14, and is placed in a predetermined position (storage position 0, anus cleaning position P, and bidet cleaning position Q). This constitutes a nozzle rod reciprocating drive mechanism 17 that stops. Reference numeral 18 denotes a cleaning water supply port constructed near the tip of the nozzle cylinder 3, which is connected to the anal spouting hole 20 or the bidet spouting hole 21 of the nozzle head 19 fixed to the tip of the nozzle rod 15, and each protrusion. A communication passage that selectively communicates with the nozzle rod 15 is constructed in the nozzle rod 15.

Reference numeral 25 in the figure is an abutting member protruding from the support bracket 5, which abuts the protruding side regulating protrusion 26a and the retreating side regulating protrusion 26b protruding from the upper surface side of the nozzle cylinder 3.
A stroke with a fine adjustment width L1, which will be described later, is ensured.

The cleaning water injection nozzle control mechanism having the above configuration is driven and controlled by a central control circuit CPU connected to an operation panel 22 via an input/output circuit 23, as shown in FIG.
The proper position of the user can also be stored by a rewritable storage circuit 24 connected to the central control circuit CPU.

Next, an example of the operation of the apparatus of the present invention will be explained according to the flowchart shown in FIG.

Put the sanitary cleaning device into use status "Start".

When either the "anus cleaning command" or the "bidet cleaning command" is selected here, the cylinder position fine adjustment drive control motor 9 is driven to rotate in the normal direction. When the cylinder position fine adjustment drive control motor 9 is driven, the rack 8 that meshes with the pinion 10 that is pivotally attached to the drive shaft changes its meshing position, so that the nozzle cylinder 3 has sliding ribs that protrude on both sides. 4.4 and protrudes along the guide groove 6°6. After that, the nozzle position change drive control motor 16 is driven to rotate in the forward direction. When the nozzle position change drive control motor 16 is driven, the plate spring 14 wound around the drum 13 is let out, causing the nozzle loft 15 to protrude from the nozzle cylinder 3. Therefore, when the "nozzle rod position" reaches the selected command position (anus cleaning position P or bidet cleaning position Q), the nozzle position change drive control motor 16 and cylinder position fine adjustment drive control motor 9 are stopped,
If there is no "nozzle position adjustment command", cleaning water is supplied to the cleaning water supply boat 18 from a hot water tank (not shown).

In this state, cleansing water is spouted from the anal water spouting hole 20 or the bidet water spouting hole 21 of the nozzle rad 19. On the other hand, if there is a "nozzle position adjustment command", it is determined whether it is "manual adjustment" or "automatic adjustment", and in the case of manual adjustment, the cylinder position fine adjustment drive control motor 9 is adjusted by operating a switch from the operation panel 22. The nozzle cylinder 3 is rotated in the opposite direction to adjust its forward and backward positions.

This fine adjustment width Ll is about 2. ocsm, and when the cylinder position fine adjustment drive control motor 9 is rotationally driven,
The nozzle cylinder 3 protrudes or retreats along the guide groove 6.

On the other hand, in the case of "automatic adjustment", the user's personal control information stored in advance in the rewritable storage circuit 24 can be read out, and the cylinder position fine adjustment drive control motor 9 can be driven in the same manner as described above.

Here, when there is a "swing cleaning command j" to clean the area around the cleaning part during cleaning, the cylinder position fine adjustment drive control motor 9
, the nozzle cylinder 3 is centered around the adjustment setting position P.
The central control unit CPU outputs a drive command for repeating forward and reverse rotation within a predetermined rotation angle range so that the motor reciprocates within a predetermined width.

According to FIG. 6, the fine adjustment width Ll indicates the rocking operation according to the drive command, for example, from the most retracted position to the most protruded position zE.
is 20 mm, swing width L2 is 10 fins (rear stroke L3
is 2.5n+ and the front stroke L4 is 7.5m). Here, L5 and L6 are the abutting member 25, the retreating side regulating protrusion 26b, and the protruding side regulating protrusion 26a.
This means that there is a gap of 0.5 mm at each contact position.

After the fine adjustment, if the adjustment position P is set to the normal operating range U1, the central controller CPU controls the cylinder position fine adjustment drive control motor 9 to the rear stroke L3 of the nozzle cylinder 3.
is 2.51 m, the front stroke L4 is 7.5 w, and the drive is controlled to have a swing width L2 of 1011. That is, this normal operating range U1 is 2 from the most retracted position.
．． 511 Pl moved to the protruding side and 7 from the most protruding position E
．． This is the range of P2 where 5 cranes moved backward.

In addition, if the adjustment position P is set outside the normal operation range U1 (U2 or U3), the most swinging backward position or the most swinging protruding position E is the most backward adjustment position of the fine adjustment width L1. Or the Low swing width L2 so as to overlap with the most protruding adjustment position E.
Control the drive so that it swings by holding it.

Next, when a "cleaning end command" is issued, the supply of cleaning water to the cleaning water supply boat 18 is first stopped, then the cylinder position fine adjustment drive control motor 9 is stopped, and the nozzle After driving the position change drive control motor 16 in the reverse direction and retracting the nozzle rod 15 until it reaches the storage position,
Waits for the next activation command signal.

〔Effect of the invention〕

Since the spray nozzle position drive control method of the sanitary cleaning device according to the present invention is configured as described above, the nozzle cylinder housing the nozzle rod that moves in and out of the storage position, anus cleaning position, and bidet cleaning position can be further adjusted in and out. When the nozzle cylinder reciprocating drive means is finely adjusted within a predetermined range and simultaneously oscillated by a predetermined width at the adjustment position, the oscillation width exceeding the extreme end of the adjustable range may exceed the expected adjustment position. To provide a sanitary washing device capable of performing sanitary and comfortable washing by controlling the drive so as to secure a predetermined swing width at a position inside the fine adjustment range when the fine adjustment width is the limit. It is something that can be done.
