2. Description of the Related Art Conventionally, there is a sanitary cleaning device for cleaning private parts of the human body, which is described in, for example, Japanese Utility Model Application No. 56-8682.

The ejection part is made up of a cylindrical nozzle body and a piston-shaped telescopic nozzle, and the telescopic nozzle expands and contracts due to the water pressure when cleaning water flows into the nozzle body, and the telescopic nozzle reaches its maximum level. Cleansing water is sprayed onto the private parts of the body in the extended position.

However, with this structure, if the water pressure on the cleaning water supply side is low, the telescopic nozzle may not be able to extend from within the nozzle body and cleaning cannot be performed, or limescale or dirt may adhere between the nozzle body and the telescopic nozzle. This resulted in disadvantages such as increased resistance during expansion and contraction, making the expansion and contraction movement of the expansion and contraction nozzle uncertain.

A cylindrical drum is fixed to the output shaft of the motor, and a bendable leaf spring is wound around the circumference of the drum, and one end of the spring is attached to the drum. a guide fixed at the same time and connected at the other end to the proximal end of the telescopic nozzle, with one end guiding the leaf spring so as to be peeled off in a direction substantially tangential to the drum, and the other end guiding the leaf spring in the forward and backward direction of the telescopic nozzle; A control system is provided between the drum and the nozzle body, and further includes a control system that controls the drive of the motor with a plurality of reed switches that provide a magnet in the telescopic nozzle and output control signals in response to the magnet, Further, the reed switch is arranged to correspond to a storage position and a cleaning position of the telescopic nozzle.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of a sanitary cleaning device according to the present invention.

In the figure, 1 is a toilet bowl, 2 is a wash water tank vertically connected to the rear end of the toilet bowl 1, 3 is a toilet seat, and 4 is a toilet lid. Furthermore, 5 is a water supply heating device that is connected to the rear end of the toilet bowl 1, and a toilet seat 3 and a toilet lid 4 are rotatably attached thereto.

This water supply heating device 5 stores water supplied from a water supply pipe connecting the water supply source and the cleaning water tank 2 via a branch fitting, and also includes a heating element such as a sheathed heater and a temperature sensor that detects the hot water temperature. A hot water storage tank is provided. In addition, it controls the temperature of the washing water heated in the hot water storage tank, and also controls the behavior of the nozzle, which will be described later, the warm air that dries the washing water that adheres to private parts, the temperature of the heated toilet seat, and all other electrical components. It has departments, etc. Further, a piping system for supplying wash water from the hot water storage tank to the spouting section is provided with necessary valves and the like.

Reference numeral 6 denotes a spouting part that is provided in the water supply heating device 5 at a position approximately corresponding to the axis of the toilet bowl 1 and spouts cleansing water to local areas, and 7 denotes a warm air outlet that opens in the vicinity of the spouting part 6 and blows out hot air. It is. The cleaning water jetting operation from the spouting part 6 is performed by a rotary dial type cleaning switch 5b provided on the panel part 5a of the water supply heating device 5, and the hot air blowing operation from the hot air outlet 7 is performed by a push button type drying switch 5c. This can be done manually.

2 and 3 show the main parts of the jetting part 6. FIG. The spouting part 6 is located within the casing 5d of the water supply heating device 5 and approximately in the vicinity of the axis of the toilet bowl 1. A nozzle body 6c is fixed to a machine frame 6a vertically disposed on the bottom plate 5e of the feed water heating device 5 and has a hollow cylindrical shape oriented toward the toilet bowl 1a of the toilet bowl 1 and has a square cover portion 6b at the tip. , a telescopic nozzle 6d forming a nozzle portion that is attached to the nozzle main body 6c so as to be freely advanced and retractable in the axial direction, a motor 6e that drives the telescopic nozzle 6d forward and backward, a leaf spring 6f that connects the motor 6e and the telescopic nozzle 6d, etc. It is composed of the main elements.

Figure 4 shows the nozzle body 6c and the telescopic nozzle 6d when cut along a plane including the - line in Figure 3.
This is a cross section of The nozzle body 6c has a hollow cylindrical shape except for the cover part 6b at the tip thereof, and the telescopic nozzle 6d is slidably inserted in the hollow part in a watertight manner, and a guide is provided on a part of the inner peripheral wall of the nozzle body 6c. A groove 6g is recessed over the entire length in the axial direction. On the other hand, a plate spring 6f is screwed to one end of the telescopic nozzle 6d (on the opposite side to the ejection hole formation position).
Both edges 6h of the leaf spring 6f can slide within the guide groove 6g. The telescopic nozzle 6d can move without rotation when moving forward or backward due to the leaf spring 6f and the guide groove 6g, and the direction of the water jetted from the jetting hole is kept constant.

At the tip of the telescopic nozzle 6d, there is a first nozzle for bidet cleaning.
A spout hole N ₁ and a second spout hole N ₂ for cleaning the anus are provided at a required interval from the first spout hole N ₁ . The first nozzle _N1 has 5 small holes,
On the other hand, the second nozzle N ₂ is provided with three small holes, and the forms of the cleaning water injected from the first nozzle N ₁ and the second nozzle N ₂ are different.

FIG. 5 is a plan view of this telescopic nozzle 6d, and FIG.
The figure is a sectional view taken along a plane including the axis.

A first flow path F ₁ that communicates the first jet hole N ₁ with the first inlet H ₁ located on the upstream side of the cleaning water.
and a second flow path F ₂ that communicates with a second inlet H ₂ that is opened on the upstream side of the cleaning water similarly to the second jet hole N ₂
are each formed to form a water flow path space in the axial direction of the expandable nozzle 6d. The distance between the first inlet _H1 and the second inlet _H2 is set to be suitable for bidet cleaning and anal cleaning.

The telescopic nozzle 6d is guided by the leaf spring 6f and the guide groove 6g of the nozzle body 6c to move forward and backward within the nozzle body 6c, and is further supported near the cover portion 6b via a packing 6i. An elbow 6j for connecting a hose for supplying hot water for washing from a hot water tank in the water supply heating device 5 is integrally connected to the cover part 6b, and a connection is made from the elbow 6j to the center of the cover part 6b. A road 6k is drilled. Further, an annular recess 6l of a required width is formed in the insertion part of the telescopic nozzle 6d of the cover part 6b so as to continue to the communication path 6k, and the aforementioned gasket 6i is installed so as to sandwich the annular recess 6l. There is.
Further, an insertion hole 6q is formed on the side of the cover portion 6b into which the tip of a tube 6p for drained water that branches on the upstream side of the hot water storage tank is inserted.

Next, a drive system including a motor 6e and a leaf spring 6f for reciprocating stroke operation of the telescopic nozzle 6d will be explained.

As the motor 6e for driving the telescopic nozzle forward and backward, a synchronous motor is used in order to keep the forward and backward speed of the telescopic nozzle substantially constant at all times, and a motor equipped with a speed reducer is used. In Figure 2, 6m is the motor 6e.
This is a cylindrical drum fixed to the output shaft of the drum 6m, and one end of a leaf spring 6f is fixed to this drum 6m. The leaf spring 6f is arranged so as to wind around the peripheral surface of the drum 6m from a fixed point with the drum 6m, and the other end is connected to the upper part of the base end of the telescopic nozzle 6d. Furthermore, 6n is a telescopic nozzle 6d from the drum 6m.
This is a guide for leaf springs that are placed up to. This guide 6n has a groove space in which the leaf spring 6f can freely slide, and as shown in FIG.
It has a function of guiding the leaf spring 6f in the direction of peeling it off from the circumferential surface of the drum 6m, and the terminal end is a telescopic nozzle 6d.
The leaf spring 6f is guided in the forward and backward direction of the movement. In order to pass through such a guide 6n and connect to the base end of the telescopic nozzle 6d, the leaf spring 6f is made sufficiently longer than the length sufficient to be wound around the drum 6m.

In the drive structure as described above, when the motor 6e operates, the drum 6m rotates, and the leaf spring 6f, one end of which is fixed to the drum 6m, operates to move the telescopic nozzle 6d by the guide 6n.

That is, when the drum 6m rotates clockwise in FIG. 2, the leaf spring 6f, which is wound around the circumferential surface of the drum 6m, is deformed so as to be separated from the drum 6m by the guide 6n. Then, when the drum 6m further rotates, the leaf spring 6f is sent to the connecting point with the telescopic nozzle 6d by the guide 6n. At this time, since the leaf spring 6f is bendable, it moves along the guide 6n while being deformed freely, and as a result, the telescopic nozzle 6d can be pushed out toward the cleaning position. Conversely, when the drum 6m is rotated counterclockwise in FIG.
d and return the leaf spring 6f to its original position. This operation allows the telescopic nozzle 6d to be pulled back to the storage position.

As described above, the leaf spring 6f arranged so as to be wound around the circumferential surface of the drum 6m is deformed so as to be peeled off from the circumferential surface of the drum 6m by the guide 6n, and the terminal end of the guide 6n is Telescopic nozzle 6d
By making it the same as the advancing and retreating direction, the forward and reverse rotational motion of the drum 6m can be converted into a reciprocating linear motion of the telescopic nozzle 6d.

By the way, the telescopic nozzle 6d moves from its storage position to the anus cleaning position or the bidet cleaning position. For this reason, the movement stroke of the telescopic nozzle 6d is the second inlet of the telescopic nozzle 6d when cleaning the anus.
H ₂ reaches the annular recess 6l of the cover part 6b as shown in FIG.
As shown in the figure, the first inlet _H1 reaches the annular recess 6l to form a flow path for each cleaning. That is, the elbow 6j, the communication path 6k, the annular recess 6
1 and one of the first and second nozzle holes N ₁ and N ₂ communicates with each other.

As described above, in order to connect the flow path for cleaning, it is necessary to determine the stroke of the telescopic nozzle 6d. And this stroke is
Since it is determined by the amount of rotation of the motor 6e,
The operation of the motor 6e is controlled using a reed switch. That is, as shown in FIG. 3, a magnet M is fixed to the connection end between the telescopic nozzle 6d and the leaf spring 6f, and a support frame 6a' connected to the machine frame 6a on the side opposite to the magnet M is fixed. Reed switches S ₁ , S ₂ and S ₃ are provided. These magnets M and each reed switch S ₁ ,
By using the signal transmission and reception by S ₂ and S ₃ , the motor 6e
The control circuit is configured to drive and stop the motor. Furthermore, if the positions of the reed switches S ₂ and S ₃ are arranged to correspond to the stroke of the telescopic nozzle 6d required for anal cleaning and bidet cleaning, the position of the telescopic nozzle 6d can also be set by the system with the magnet M. It is.

In controlling the operation of the telescopic nozzle 6d, for example, when the cleaning switch 5b is turned on to clean the anus, the motor 6e rotates and the telescopic nozzle 6
d begins to extend, and magnet M turns the reed switch.
The motor 6e is stopped by a signal corresponding to _S2 , and the telescopic nozzle 6d is set to the anus cleaning position. Furthermore, when the cleaning switch 5b is turned off, the motor 6e rotates in the opposite direction to move the telescopic nozzle 6d backward, and when the magnet M corresponds to the reed switch _S1 , the operation of the motor 6e is stopped and the telescopic nozzle 6 is moved backward.
d can be returned to the storage position.

As described above, the operation of the telescopic nozzle 6d, which moves linearly in a reciprocating manner using the leaf spring 6f, is controlled by the magnet M and the reed switches S ₁ , S ₂ , and S ₃ . The position of the telescopic nozzle 6d is also set by these control elements, and as a result, the telescopic nozzle 6d is automatically stored and moved to the cleaning position.

FIG. 8 is a flowchart of the cleaning water, showing the flow of the cleaning water from the water supply source to the telescopic nozzle 6d, and the cleaning water is discharged by opening the electromagnetic valve _VM . The opening/closing operation of the solenoid valve V _M is performed by the control unit in response to a position detection signal of the telescopic nozzle 6d from the magnet M and each reed switch S ₁ , S ₂ , S ₃ . The nozzle 6d is turned on and off at appropriate times based on position detection, and the cleaning procedure will be described below.

First, in the case of anal cleaning, when the cleaning switch 5b is turned on to the anal cleaning side, the motor 6e rotates and the telescopic nozzle 6d is extended in the direction of the toilet bowl 1a by the drum 6m and leaf spring 6f, as shown in FIG. When the magnet M reaches the reed switch _S2 position, the control section receives a signal from both of them and stops the motor 6e. At this time, as described above, by adjusting the stroke of the telescopic nozzle 6d, the second inlet
_H2 communicates with the elbow 6j on the water supply source side via the communication path 6k and the annular recess 6l, and the solenoid valve V
Since valve _M is also opened at the same time, cleansing water at a comfortable temperature flows down the second flow path _F2 from the hot water storage tank and is discharged from the second jet hole _N2 to perform anal cleansing. After cleaning is completed, turn off the cleaning switch 5b and the solenoid valve V
_M closes and discharge stops, and at the same time magnet M closes and discharge stops.
The motor 6e is reversed by the control unit which receives the signal from the reed switch _S2 , and the telescopic nozzle _6d moves to the storage position, that is, the non-operating position. The motor 6e stops and the telescopic nozzle 6d is housed in the nozzle body 6c, completing one cleaning process.

On the other hand, in the case of bidet cleaning, the cleaning switch 5b is turned on to the bidet cleaning side, which causes the telescopic nozzle 6d to extend in the same way as above, but in this case, due to the configuration of the control circuit, the magnet M will not move until it corresponds to the reed switch _S3 . It is extendable, which allows the elbow 6j
and the first inlet _H1 are in communication with each other, and when the solenoid valve V _M is opened, cleaning water is jetted out from the first jetting hole _N1 to perform cleaning, and when the cleaning is finished, by turning off the cleaning switch 5b. Similarly to the above, the telescopic nozzle 6d can be stored by the correspondence between the magnet M and the reed switch _S1 .

In this embodiment, a circuit is built in which alternately repeats normal and reverse rotation of the motor 6e every few seconds at the operating position of the telescopic nozzle 6d, and this circuit is selectively used with a changeover switch. It is also possible to move the body back and forth with a slight stroke to automatically change the location on the body where the cleansing water hits, further enhancing the cleansing effect.

〔Effect of the invention〕

As described above, the sanitary cleaning device according to the present invention has the following effects due to its configuration.

(1) The telescoping nozzle of the spouting part that spouts out cleaning water is moved telescopingly by an electric drive device.
The telescopic nozzle operates reliably, allows accurate local cleaning, and does not depend on the level of water pressure on the cleaning water supply side, so it can be widely used regardless of where the device is installed.

(2) Since the telescopic nozzle is extended and contracted by electric drive, the operation can be easily controlled, and the operating position of the telescopic nozzle can be arbitrarily adjusted, making it easy to use.

(3) The flexible leaf spring that converts the rotational motion of the motor output shaft into reciprocating linear motion of the telescopic nozzle is wound around the drum circumferential surface, making it possible to simplify and downsize the conversion mechanism. Therefore, the degree of freedom in placement in the feed water heating device, which is limited by device capacity, is improved, and design restrictions such as competition in installation dimensions with other devices can be relaxed.
