Description

[Detailed description of the invention] [Industrial application field] This invention relates to a sanitary cleaning device with a private part cleaning function,
In particular, the present invention relates to a nozzle device that makes it easy to clean a nozzle that spouts cleaning water.

C. Prior Art] A sanitary washing device equipped with a private parts washing function generally has a structure in which heated washing water is sprayed toward the private parts by a nozzle device, an example of which is shown in FIG.

In the figure, a casing 1 of a sanitary cleaning device is fixed to a toilet main body 50, and a toilet seat 1a and a toilet lid 1 are attached to this casing 1.
b is attached so that it can be opened and closed. A tank for heating washing water, a hot air fan for drying, and a control section are built inside the casing 1, and each function is operated by an operation section 2 provided on the top surface of the casing 1. A nozzle device f3 is incorporated into the casing 1, and the nozzle device 3 includes a nozzle main body 4 that advances to a cleaning position and a nozzle radiator 4a provided at the tip of the nozzle main body 4.

The nozzle device 3 is equipped with a motor for moving the nozzle body 4, and the nozzle body 4 is set to the anal cleaning position or the bidet position by a switch on the operation part 2, and after cleaning, the nozzle body 4 is returned to the storage position in the casing 1. will be returned to. When the cleaning switch is pressed, a solenoid valve provided in the piping with the heating tank opens according to each position of the movement of the nozzle body 4 to the cleaning position, and cleaning water is sprayed from the rad 4a to the nozzle. be done.

[Problem to be solved by the invention]

When the nozzle main body 4 and the nozzle head 4a are not in use, they are housed in the casing 1, so they cannot be seen from the outside.

Therefore, when cleaning the nozzle body 4 or the rad 4a on the nozzle, it is necessary to pull out the nozzle body 4.

However, when the nozzle main body 4 is taken out using the operation part 2, the cleaning water flows into the nozzle according to the control sequence.
It is ejected from a. For this reason, when cleaning the nozzle body 4, the cleaning water may splash to the outside of the toilet bowl body 50, and the cleaning person may be exposed to the cleaning water. Therefore, when cleaning the nozzle, one has to press the nozzle aperture formed in the rad 4a with one's fingers, making it impossible to perform sufficient wiping.

Also, if the amount of washing water is minimized, it will be possible to
Since there is less water blowing out, cleaning becomes much easier. However, if a seat switch is provided to prevent flushing water from being sprayed unless a person is seated on the toilet seat 1a, for example, the user must place their hand on the toilet seat 1a and push it so that the seat switch is turned on. . For this reason, only one hand can be used to clean the nozzle body 4, which also poses a problem in that it is difficult to clean the nozzle body 4.

The problem to be solved by the present invention is to prevent cleaning water from blowing out even when the nozzle body is advanced when cleaning it, and to enable easy wiping of the nozzle body and nozzle head.

[Means for Solving Problem 1liI] The present invention includes a nozzle body that communicates with a cleaning water source and moves forward and backward between a storage position in a casing and a cleaning position by a drive device, and when the nozzle body is in the cleaning position. A sanitary cleaning device configured to eject cleaning water from a nozzle head at the tip when the nozzle reaches the nozzle body, the sanitary cleaning device comprising nozzle control means for stopping the supply of cleaning water to the nozzle body and causing the nozzle body to reciprocate. Features.

[Effect]

When advancing the nozzle body of the nozzle device, if the supply of cleansing water from the cleansing water supply system is stopped, no cleansing water will be discharged from the nozzle head of the nozzle body. Therefore, when cleaning the nozzle body or nozzle head, the supply of cleaning water can be stopped and only the nozzle body can be fed out.

Therefore, the person cleaning the nozzle body and the nozzle head can easily clean the nozzle body and the nozzle head without being exposed to cleaning water or blocking the ejection holes of the nozzle head with their hands.

〔Example〕

Fig. 1 is a left side view showing the main parts of the nozzle device of the present invention, Fig. 2 is a schematic diagram showing the washing water supply system, and Fig. 3 is a perspective view of an example in which the sanitary washing device is installed in the toilet bowl body. be.

The casing 1 of the sanitary washing device is fixed to the toilet main body 50 as shown in Fig. 3, and inside the casing 1 there is a jll! As shown in FIG. 2, a heating tank lc, a valve unit 1d, and a control section 1e are housed. Further, a nozzle device 3 that advances to a cleaning position and spouts cleaning water is incorporated in the casing l.

The nozzle device 3 has a base 3 fixed inside the casing 1.
a, and a nozzle body 4 is incorporated into this base 3a so as to be movable in its axial direction. The base 3a has a concave sliding surface that receives the lower surface of the vibrator-shaped nozzle body 4, and has a cleaning chamber 3b at the tip for washing the rad 4a to the nozzle of the nozzle body 4.
has been established. Further, a drive motor 5 is provided on the base end side of the base 3a, and its output shaft is connected to the nozzle body 4 by a mechanical means such as a belt, and the nozzle body 4 is moved to the cleaning position and stored by forward and reverse rotation of the output shaft. Move back and forth between the positions. Note that when the nozzle main body 4 is returned to the storage position, the cleaning chamber 3b
It has an axis that fits within the .

The nozzle body 4 has two channels formed inside, one for anal cleaning and the other for bidet.

And two supply pipes 5a from the valve unit IC,
5b are connected to these flow paths, respectively, so that when one of the cleaning positions is reached, cleaning water can be jetted to the nozzle from the jet hole formed in the rad 4a. In order to follow the movement of the nozzle body 4, flexible supply pipes 6a and 5b are used.

FIG. 4 is a detailed view of the operation unit 2, including a stop switch 2a for stopping functions such as washing and drying, a first switch 2b for anal washing, a second switch 2C for bidet, and a warm air built into the casing 1. Drying switches 2d are arranged to operate a fan (not shown). Further, a set of flow rate setting switches 2e and 2f for increasing and decreasing the flow rate of the cleaning water is provided, and an indicator lamp 2g is arranged to display the increase/decrease of the flow rate in seven steps starting from the minimum flow rate. When the flow rate setting switches 2e and 2f are operated, the opening degree of the valve built into the valve unit 1d changes to set the flow rate. Examples of such valve mechanisms include needle valves that have a needle as a valve body that can be moved forward and backward by an electric motor, and valves that have a piezoelectric actuator using a piezoelectric element as a drive source for the valve body.

When the first switch 2b is pressed, a valve in the valve unit 1d opens, and after a predetermined period of time has elapsed and this valve is closed, the drive motor 5
is activated, and when the nozzle head 4a reaches its cleaning position, the valve in valve unit 1 (I) is opened and cleaning water is jetted out.Then, when the stop switch 2a is pressed after use, the valve in valve unit 1 (I) is closed. Subsequently, the output shaft of the drive motor 5 is reversed to return the nozzle body 4 into the casing 1, and after opening the valve in the valve unit 1d, it is closed again and the jetting of the cleaning water is also stopped.

Also, when the second switch 2C is pressed, the nozzle body 4
advances to the cleaning position, and after use, the nozzle body 4 can be returned to the storage position by pressing the stop switch 2a. In addition,
The jetting of the cleaning water is the same as in the case of the first switch 2b.

Here, as shown in FIG. 2, a seating sensor 1f for the toilet seat 1a is provided so that the cleaning water from the nozzle body 4 does not spout unless a person is seated on the toilet seat la. As the seating sensor lf, a pressure-sensitive type sensor provided on the back surface of the toilet seat 1a or a photoelectric type sensor using infrared rays or the like is used. Then, the signal of the seating sensor 1f is manually inputted to the control unit 1e,
The cleaning water is controlled to be ejected from the nozzle body 4 only when the seating sensor 1f is on. That is, if no person is sitting on the toilet seat 1a, the first flush switch 2b
Even if you press the button or the second cleaning switch 2C, the valve unit Hb
The valve remains in an inoperative state, and the drive motor 5 remains inoperative.

FIG. 5 is a flowchart of the control system for cleaning the nozzle body 4 and the nozzle rad 4a, and FIG. 6 is a time chart.

As can be seen from these figures, if a person is sitting on the toilet seat 1a and there is no occupancy detection signal from the occupancy sensor 1[, and the stop switch 2a is pressed for more than 3 seconds as shown in Fig. 6(a), , the drive motor 5 is operated to advance the nozzle body 4 to the cleaning position shown in FIG. At this time, the valve of the valve unit 1d remains closed, and no cleaning water is ejected from when the nozzle body 4 starts moving until it stops.

Even if the fingertip is removed from the stop switch 2a, the nozzle body 4 will stop as shown in FIG. 1. therefore,
The nozzle body 4 and the nozzle head 4a are in a state of being protruded from the casing 1, and there is no spray of cleaning water from the nozzle rad 4a, so the person cleaning the nozzle body 4 and the nozzle head 4a must use both hands to thoroughly clean the nozzle body 4 and the nozzle head 4a. Can be wiped clean.

When the stop switch 2a is pressed again after cleaning is completed, the output shaft of the drive motor 5 is reversed and the nozzle body 4 is housed in the casing 1. During this storage operation, the valve of the valve unit 1d remains closed and no cleaning water is ejected, and when the nozzle body 4 is stored in the casing 1, the drive motor 5 stops. And after this storage, the first
When the switch 2b, the second switch 20, etc. is pressed, the nozzle main body 4 advances and the cleaning water is supplied from the valve unit 1d as usual.

Furthermore, if the stop switch 2a is held down for more than 10 seconds as shown in FIG. 6(b) during cleaning, the control unit 1 will operate the drive motor 5 so that its output shaft rotates in the reverse direction, and the nozzle body 4 will be rotated. Stored in casing 1. By canceling the cleaning mode in this manner, even if a short-circuit failure or the like occurs in the operating section 2, the nozzle body 4 will not be left exposed.

The above operation of the drive motor 5 and maintenance of the valve unit 1d in the closed state are possible only when the seating sensor 1f is off, that is, when no person is sitting on the toilet seat 1a. By operating the stop switch 2a when storing the nozzle body 4, the control is switched to the normal cleaning mode at the same time as the nozzle body 4 is retracted. therefore,
There is no need for a special switch to switch from cleaning mode to normal cleaning mode, making it easy to operate.

Furthermore, when the seating sensor 1f is on, the stop switch 2
Even if you press a, the drive motor 5 will not operate. Therefore, even if a person accidentally presses the stop switch 2a for more than 3 seconds while sitting on the toilet seat 1a, the nozzle body 4
remains stopped inside the casing 1. Therefore, the nozzle body 4 and the nozzle head 4a are not covered with dirt, etc., and can be advanced to the cleaning position for cleaning only by operating the first or second switch 2b, 2C.

〔Effect of the invention〕

In the present invention, the nozzle body can be extended to the cleaning position without supplying cleaning water to the nozzle body. Therefore, when wiping the nozzle body or the nozzle head at its tip, there is no water blowing out from the nozzle head, so you can easily clean the nozzle body or nozzle head with both hands without blocking the nozzle or the like with your hands. I can do it. Therefore, the nozzle head etc. can always be kept clean and used hygienically.
