Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sanitary cleaning device that can clean private parts hygienically and comfortably.

BACKGROUND ART Conventionally, there is a sanitary cleaning device for cleaning private parts of the human body, which is described in, for example, ``Kokai Publication No. 8682/1982''. This system consists of a cylindrical nozzle body that spouts cleansing water and a piston-like telescopic nozzle that can slide freely inside the nozzle body, which is connected to the toilet bowl side, and opens the solenoid valve. The extensible nozzle is moved back and forth by the action of the cleaning water pressure, and the position where the extensible nozzle extends the maximum amount is set as the cleaning position, and the cleaning water is sprayed to the private parts.

However, in the ejection section having such a structure, at the beginning of cleaning, washing water is ejected from the ejection hole of the telescopic nozzle that extends in response to water pressure. That is, at the same time as the telescopic nozzle begins to extend, cleaning water is jetted out from the jet hole, and in this state of jetting cleaning water, the telescoping nozzle extends and moves to its cleaning position, and in this process, the cleaning water does not reach areas other than the private parts. There was a drawback that the same area got wet when touched. In addition, the cleaning water that is ejected at the start of cleaning remains at a low temperature because it remains in the piping system between the heating device and the telescopic nozzle, and direct contact with this residual low-temperature water can be extremely unpleasant. However, the problem remains that it is not easy to use.

The present invention aims to solve the above-mentioned drawbacks, and is a sanitary cleaning device equipped with a spouting part that spouts cleansing water to private parts. The purpose is to enable cleaning by

The basic structure of the present invention is that, in a sanitary washing device equipped with a jetting part that jets out cleaning water, a nozzle body is provided in the jetting part, a telescoping nozzle guided by the nozzle body, and an electric current that drives the forward and backward movement of the telescoping nozzle. The driving means is provided with an electrically operated valve and a heater that heats the washing water in the water supply heating part that supplies washing water to the expandable nozzle, and the operating means and the controller are provided in the operation control part, respectively.
When the controller starts cleaning, the electrically operated valve is first opened for a predetermined time in the non-operating position with the telescoping nozzle housed in the nozzle body, and the pipe system between the heater of the feed water heating section and the telescoping nozzle is opened. the remaining water is discharged, and then the electrically operated valve is opened and the electrically driven means is driven to extend the telescopic nozzle from the non-operating position so that the ejection hole is directed toward the location to be cleaned. position, and when the operating position is reached, the driving of the electric drive means is stopped, the telescopic nozzle is placed in the operating position, and the electrically operated valve is opened again to supply hot cleaning water from the ejection hole of the telescopic nozzle. It is designed to be squirted towards the local area.

A motor 6e that drives forward and backward d, and the same motor 6
The main elements include a plate spring 6f that connects the telescopic nozzle 6d and the telescopic nozzle 6d.

Figure 4 shows the nozzle body 6c and the telescopic nozzle 6 when cut along a plane including the line - in Figure 3 above.
d is shown, and the nozzle body 6c has a hollow cylindrical shape except for the cover part 6b at the tip,
A telescopic nozzle 6d is slidably inserted into the hollow portion, and a guide groove 6g is recessed in a part of the inner circumferential wall of the nozzle body 6c over the entire length in the axial direction. On the other hand, a plate spring 6f is screwed to one end side of the telescopic nozzle 6d (the side opposite to the position where the ejection hole is formed), and a peripheral edge 6h of the leaf spring 6f can slide within the guide groove 6g. Due to the leaf spring 6f and the guide groove 6g, it is possible to move without rotation when advancing and retreating, and the direction of the water jetted from the jetting hole, which will be described later, can be kept constant.

A first ejection hole _N1 for bidet cleaning and a second ejection hole _N2 formed at a required interval from the first ejection hole _N1 are provided at the tip of the extendable nozzle 6d. Fifth
The figure is a plan view of the telescopic nozzle 6d, and Figure 5a is a cross-sectional view including the axis, which communicates the first jet hole _N1 with the first inlet _H1 located upstream of the cleaning water. A second flow path F ₂ that connects the first flow path F ₁ and a second inlet H ₂ which is opened on the upstream side of the cleaning water similarly to the second jet hole N ₂ is a telescopic nozzle 6d.
It is formed to form a water flow path space in the axial direction.
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 6b via a packing 6i. An elbow 6j that connects a hose for supplying hot water for cleaning from the hot water tank 8 in the water supply heating device 5 is integrally connected to the cover portion 6b, and a connection is made from the elbow 6j toward the center of the cover 6b. A road 6k is drilled. In addition, an annular recess 6 of a required width is formed in the insertion portion of the telescopic nozzle 6d of the cover portion 6b so as to continue with the communication path 6k, and the aforementioned gasket 6i is mounted to sandwich the annular recess 6. There is.

In addition, an insertion hole 6q is formed on the side of the cover portion 6b, into which a distal end portion of a permanent discharge tube 6p branching on the upstream side of the hot water storage tank 8 is inserted.

FIG. 5b shows a cross section of the tip of the telescopic nozzle 6d when the telescopic nozzle 6d is in the non-operating position, that is, housed in the nozzle body 6c, and shows the second ejection hole.
On the outer peripheral surface of the telescopic nozzle 6d on the rear side from N ₂ ,
A notch G for draining residual water having a required depth is provided on the opening forming side of the first and second jet holes N ₁ and N ₂ . As shown in FIG. 5b, the length of the residual water discharge notch G in the axial direction of the telescopic nozzle 6d is longer than the distance between the annular recess 6 of the cover part 6b and the fitting part of the gasket 6i on the distal end side. When the telescopic nozzle 6d is housed in the nozzle body 6c, the elbow 6j on the water supply side and the residual water discharge notch G communicate with each other via the communication path 6k and the annular recess 6, as shown in FIG. 5c. The water that remains in the piping system due to the temporary opening of the solenoid valve by the controller, which will be described later, is removed from the elbow 6.
j, through the communication path 6k, the annular recess 6, and the notch G for draining residual water, it reaches the opening forming part of the first and second nozzle holes N1 _{, N2} , and the remaining cold water is discharged and discharged locally. At the same time, the tip of the telescopic nozzle 6d closest to the can be cleaned.

The forward and backward movement of the telescopic nozzle 6d is performed by a motor 6e and a leaf spring 6f, and the motor 6e is a synchronous motor and is equipped with a speed reducer in order to keep the forward and backward speed of the telescopic nozzle 6d substantially constant. In Fig. 2, 6m is a drum rotationally driven by a motor 6e, and this drum 6m
Fix one end of the leaf spring 6f to and wind it,
The other end of the leaf spring 6f is connected to the upper end of the telescopic nozzle 6d. Furthermore, 6n is a guide for a leaf spring arranged from the drum 6m to the telescopic nozzle 6d,
The rotation of the drum 6m causes the leaf spring 6f to extend and contract while being guided by the leaf spring guide 6n, thereby allowing the telescopic nozzle 6d to move forward and backward.

The telescopic nozzle 6d moves from its storage position to the anus cleaning position or the bidet cleaning position, but this movement stroke is caused by the second inlet _H2 of the telescopic nozzle 6d when cleaning the anus.As shown in FIG.
On the other hand, during bidet cleaning, the first inlet H ₁ reaches the annular recess 6 as shown in FIG. 6 to form a flow path for each cleaning. That is, the elbow 6j, the communication path 6k, and the annular recess 6 are in communication with either the first or second ejection holes _N1 , _N2 . The stroke of the telescopic nozzle 6d is determined based on the amount of rotation of the motor 6e, but in this embodiment, a reed switch is used to drive and stop the motor 6e. That is, in FIG. 3, there is a magnet M at the connection end between the telescopic nozzle 6d and the leaf spring 6f.
is fixed, and a reed switch is attached to a support frame 6a' connected to the machine frame 6a on the side opposite to the magnet M.
S ₁ , S ₂ , and S ₃ are provided, and a control circuit is constructed so that the motor 6e is driven and stopped by both of them.By appropriately positioning the reed switches S ₂ and S ₃ , It is possible to reliably obtain the stroke of the telescopic nozzle 6d required for the above-mentioned anal cleaning and bidet cleaning.

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 discharge of the cleaning water is performed by opening a solenoid valve _VM , which is an electrically operated valve. conduct. The opening/closing operation of this solenoid valve V _M is performed using a magnet M and each reed switch S ₁ ,
The controller unit receives the position detection signal of the telescopic nozzle 6d from S ₂ and S ₃ , and the motor 6e is similarly turned on and off as appropriate based on the position detection of the telescopic nozzle 6d.

A controller unit C ₂ that controls the on-off valve of the solenoid valve V _M and the drive of the motor 6e and its forward and reverse rotation is built into the feed water heating device 5, and the controller unit C ₂ controls the above-mentioned telescopic nozzle 6.
This is done in response to a signal from the position detection of d and a condition signal indicating whether it is an anal cleaning or bidet cleaning from the cleaning switch _5b of the operating section _{C1 .} A time chart of the motor 6e is shown, and the cleaning process will be explained below based on this diagram.

First, when the cleaning switch 5b is turned on to the anus cleaning side (time: t ₀ ), the controller section C ₂ receives this signal and turns on the solenoid valve _VM , and the time required from time t ₀ to t ₁ is the same solenoid valve _VM. becomes open. As a result, the cleaning water flows down from the cleaning water tank 2 toward the hot water storage tank 8, and is discharged from the elbow 6j of the spouting part 6 through the residual water discharge notch G as described above, pushing out the remaining cold water. . The time required for this discharge, that is, the time between times t ₀ and _{t 1} is determined by the time required for the hot water storage tank 8 with a built-in heater.
From then on, the amount of water remaining in the piping system leading to the spouting part 6 can be discharged. At time t ₁ after this residual water is discharged, the solenoid valve V _M closes, the motor 6e is driven, and the telescopic nozzle 6d is moved from the storage position within the nozzle body 6c. That is, the motor 6e
rotates, and the drum 6m and leaf spring 6f cause the telescopic nozzle 6d to extend toward the toilet bowl _1a as shown in FIG. In response, the motor 6e stops.

During the extension time t ₁ to _{t 2} of the telescopic nozzle 6d, the solenoid valve _VM is closed in the OFF state, so water is not spouted and the anus cleaning position can be reached. Next, the controller section receives a signal corresponding to the reed switch S ₂ for the magnet M, and at time t ₂
At this point, the driving of the motor 6e is stopped, and at the same time, the solenoid valve _VM is turned on and opened again, and the hot water heated in the hot water storage tank 8 is supplied to the spouting part 6. In this case, 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 side via the communication passage 6k and the annular recess 6, and the solenoid valve V _M also communicates with the elbow 6j on the water supply source side through the communication passage 6k and the annular recess 6. Since the valves open at the same time, cleansing water at a comfortable temperature flows from the hot water tank 8 to the second flow path F2 _.
The liquid flows down and is discharged from the second ejection hole _N2 to clean the anus. After cleaning is completed, if the cleaning switch 5b is turned off, at time _t3 , the solenoid valve V _M closes and the discharge stops, and at the same time, the controller receives the signal from the magnet M and the reed switch _S2, and the motor 6e is reversed. Then, the telescopic nozzle 6d moves to the storage position, and along with this movement, the magnet M
When reed switch S ₁ responds, motor 6e
stops and at time t ₄ The telescopic nozzle 6d is the nozzle body 6
The cleaning process is completed by being housed in the container c.

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 communicate with each other, and when the solenoid valve _VM 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 accommodated by the correspondence between the magnet M and the reed switch _S1 .

A block diagram of one embodiment of the circuit of the operation control section C is shown in FIG. In this figure, the flow of the ON signal of the cleaning switch 5b of the operating section _C1 is shown by a solid line arrow, and the OFF signal of the cleaning switch 5b is shown by a chain line arrow.

The present invention can be modified in various ways. For example, an electric valve or an electric pump may be used instead of a solenoid valve as the electrically operated valve.

As described above, according to the present invention, the electrically operated valve is opened for a predetermined period of time in the non-operating position of the telescopic nozzle that spouts cleaning water, and the piping system between the telescopic nozzle and the heater position that warms the cleaning water is controlled. After the remaining water is drained, the electrically operated valve is closed, and when the telescopic nozzle is brought to the operating position by the electric drive means, the electrically operated valve is opened again and hot water for cleaning is jetted toward the private parts. Therefore, there is no need to wet areas other than the private parts or allow cold residual water to come into contact with the human body, resulting in a comfortable cleaning experience.
