[Problems to be solved by the invention]
By the way, patients with hemorrhoids prefer soft cleaning in which the gently flushing water is applied locally. In contrast, the general public prefers a relatively strong water force.
In addition, hemorrhoid patients and the general public prefer not only the difference in water pressure but also the area of water flux hitting the anus, hemorrhoid patients prefer to be wider than the sense of water, and ordinary people do not like that much water sense. Things.
[0005]
In contrast to the actual situation where the condition of the flush water is different between the hemorrhoid patient and the general person in this way, the conventional flush toilet seat device only has a water pressure adjusting function. There is a problem that the operation is troublesome and the operation is troublesome, and the hemorrhoid patient cannot adjust to the optimum washing water condition because there is no feeling of water volume.
[0006]
Since the area of the water bundle hitting the anus is adjusted only by the total area (opening) of the nozzle hole formed at the tip of the nozzle, the opening of the nozzle hole can be adjusted by a hemorrhoid patient and a general person. To do this, a variable throttle mechanism must be provided at the tip of the nozzle, and the tip of the nozzle becomes extremely complicated, which is not practical.
In view of the above-described circumstances, the present invention provides an optimal treatment without disturbing the operation of both hemorrhoid patients and the general person by providing at least a third cleaning means for the hemorrhoid patient whose water force is different from that of the general person. An object of the present invention is to provide a flush toilet seat device that can be used in a flush water state.
[0007]

【Example】
Hereinafter, an embodiment of the cleaning toilet seat device according to the present invention will be specifically described with reference to FIGS.
As shown in FIG. 1, the flush toilet seat device of the present embodiment holds a main body casing 2 installed at a rear portion of a toilet bowl 1 and is displaceably held by the main body casing 2 in an inclined state and a superposed state with respect to the toilet bowl 1. A toilet tank 3 is provided with a toilet lid 3 and a toilet seat 4, and a hot water tank 5 for warming and successively storing washing water from a water supply means 6 (see FIG. 4) such as tap water in the main casing 2. And a cleaning unit 7 for discharging the cleaning water in the inside toward the human body part.
[0014]
As shown in FIG. 2, the cleaning device section 7 includes an anal cleaning means 8, a bidet cleaning means 9, and a third cleaning means 10 for a hemorrhoid patient. The washing water is selectively discharged by a three-way switching valve 11 to which the washing water from 5 is supplied.
The anal cleaning means 8, the bidet cleaning means 9 and the third cleaning means 10 have an inlet 8a into which the cleaning water from the three-way switching valve 11 is introduced as shown in FIG. And a nozzle 82 inserted in the cylinder 81, and a return spring 83 for urging the nozzle 82 in the retracting direction is mounted between the cylinder 81 and the nozzle 82.
[0015]
A nozzle hole 84 is formed at the tip of the nozzle 82, and the nozzle 82 can be displaced between a target position in which the nozzle hole 84 side protrudes a predetermined amount from one end of the cylinder 81 and a retracted position substantially housed in the cylinder 81. It has become.
Here, as shown in FIG. 2, the nozzle hole 104 of the third washing means 10 for hemorrhoid patients is set to have a large opening so that the amount of washing water is larger than that of the nozzle hole 84 of the anal washing means 8, and , The water is weak.
[0016]
In FIG. 3, a valve body 85 is fitted on the base end side of the nozzle 82, and the valve body 85 is formed by a biasing spring 86 having a spring constant larger than that of the return spring 83 so that the valve hole is always a water passage. Is urged to the left as viewed in the figure. The reason why the spring constant of the urging spring 86 is made larger than that of the return spring 83 is because the advancing force of the nozzle 82 is obtained by the cleaning water pressure, so that the valve hole is not opened before the nozzle 82 does not advance to the target position. It is.
[0017]
A side port 8b is formed in the cylinder 81, and the side port 8b is provided with a three-way switching valve 11 for flushing water in the cylinder 81 when returning the nozzle 81 at the target position to the retracted position, as described later. Return to the hot water tank 5. .
The configuration of FIG. 3 is basically the same for the bidet cleaning means 9 and the third cleaning means 10.
[0018]
The outlet of the hot water tank 5 is provided with a pressure valve 12 for preventing backflow and maintaining a constant water pressure by the water supply means 6. The pressure valve 12 is connected to a main valve of the three-way switching valve 11 via a water supply pipe 13. Connected to inlet 11a.
The three-way switching valve 11 has a main inlet 11a, three outlets 11b to 11d, and an auxiliary inlet 11e, and is a valve body that performs both switching and flow control. The outlets 11b to 11d are respectively connected to the cylinder inlet 10a of the third washing means 10, the cylinder inlet 8a of the anal washing means 8 and the cylinder inlet 9a of the bidet washing means 9 via water supply pipes 14 to 16, respectively, and are switched in three directions. As shown in FIG. 4, the auxiliary inlet 11e of the valve 11 is connected to a side port 10b of the third cleaning means 10, a side port 8a of the anal cleaning means 8 and a side port of the bidet cleaning means 9 through a drain pipe 17. 9b. This is because when any one of the nozzle 102 of the third cleaning means 10, the nozzle 82 of the anal cleaning means 8 and the nozzle 92 of the bidet cleaning means 9 is returned to the retracted position, the cleaning in each of the cylinders 101, 81 and 91 is performed. This is for returning water to the hot water tank 5 via the three-way switching valve 11.
[0019]
Specifically, the three-way switching valve 11 mainly includes a fixed disk, a rotating disk, and a stepping motor, and drives the rotating disk with the stepping motor to change the rotation phase of the rotating disk with respect to the fixed disk. The opening and closing of a valve hole serving as a passage for washing water to each of the washing means 8 to 10 and the opening degree can be adjusted. That is, the third washing means 10 for hemorrhoid patients can also adjust the amount of water.
[0020]
The cleaning means 8 to 10 are fixed to a bracket 18, and the bracket 18 is fixed to the main casing 2.
In the cleaning toilet seat apparatus configured as described above, the three-way switching valve 11 is operated by, for example, selecting a cleaning button provided on the operation unit of the main body casing 2, and the anal cleaning means 8, the bidet cleaning means 9, and the third Cleaning water can be discharged from any one of the cleaning means 10 of the above.
[0021]
Therefore, when used by a hemorrhoid patient, by selectively operating the third cleaning means 10, cleaning water having a larger amount of water than the nozzle hole 104 of the nozzle 102 and a weak water force is obtained, and the hemorrhoid patient enjoys soft cleaning. be able to.
On the other hand, a general person or a woman can select the normal anal cleaning means 8 or the bidet cleaning means 9 as before.
[0022]
Thus, according to the present flush toilet seat device, it is not necessary to frequently adjust the water force between the general person and the hemorrhoid patient, and the operation is relieved.
In particular, in the above-described embodiment, the three-way switching valve 11 corresponds to each of the three types of cleaning means 8 to 10, so that the size can be reduced and the storage in the main body casing 2 can be improved.
[0023]
Means for weakening the water force can be achieved by increasing the opening degree of the nozzle hole 84, but can also be achieved by making the inner diameter of the tip portion of the nozzle 102 smaller than the inner diameter of the anal cleaning means 8 in addition to this. Is done. Also, the three-way switching valve 11 can reduce the water force. In this case, the valve hole diameter when the three-way switching valve 11 guides the cleaning water to the third cleaning means 10 may be smaller than the valve hole diameter when the cleaning water is guided to the anal cleaning means 8. In addition, even if the amount of water supplied to the third washing means 10 and the anal washing means 8 is the same, when the foaming means is added to the third washing means 10, the water force is reduced.
[0024]
By the way, when the above three types of washing means 8 to 10 are provided, the washing water switching water circuit uses the washing water from the hot water tank 5 and the third washing means 10 and the downstream anal washing as shown in FIG. An upstream two-way switching valve 19 for selectively supplying water to the means 8 and the water supply pipe 21 to the bidet cleaning means 9, and selectively supplying water for cleaning the water supply pipe 2 to the anal cleaning means 8 and the bidet cleaning means 9. And a later two-way switching valve 20.
[0025]
With such a configuration, it is also possible to selectively supply cleaning water to the anal cleaning means 8, the bidet cleaning means 9 and the third cleaning means 10.
The configuration using these two switching valves 19 and 20 does not waste the existing valves or the anal cleaning means 8 and the bidet cleaning means 9 on the sold products having the anal cleaning means 8 and the bidet cleaning means 9. Cleaning means 10 for hemorrhoid patients can be added. That is, a unit including the switching valve 19 and the third cleaning means 10 may be connected instead of the water supply pipe between the hot water tank 5 and the existing valve.
