Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sanitary cleaning device that can arbitrarily change the jetting pattern of cleaning water on a toilet seat.

A conventional sanitary cleaning device of this type was constructed as shown in FIGS. 1 and 2. That is, in FIGS. 1 and 2, 1 is a toilet bowl, 2 is a low tank, 3 is a main body case, 4 is a toilet seat, and 5 is a toilet lid. Reference numeral 6 denotes a nozzle body, which is supported by the main body case 3, and a jet hole 7a provided at the tip of the nozzle body 6 is reversed and replaced with a jet hole 7b by operating a switching lever 8. Although not shown, the water supply means is disposed within the main body case 3 and communicates with the nozzle body 6.

There are two types of cleansing toilet seats, one for the anus and one for the bidet, and recently there has been an increase in the number of toilet seats that can be used for both purposes. It is necessary to arbitrarily switch and select the jetting pattern of the cleaning water. The jetting pattern is switched by combining the jetting direction of the cleaning water, the diameter or number of pores forming the jetting holes, etc., to obtain the optimal cleaning effect depending on the area to be cleaned. In the conventional example shown in FIGS. 1 and 2 above, the switching lever 8 is manually operated to switch the jetting pattern, but
a, 7b and the switching lever 8 are located at the back of the toilet bowl 1 in order to avoid the adhesion of filth when emptying the toilet, so it is difficult to recognize the switching state. There was a problem in which the water supply means was inadvertently energized without matching and wet the excess area.

3 and 4 show another conventional example, in which 9 is a toilet seat, 10 is a nozzle body which is pivotally supported by a main body case 11 and rotated by a switching lever 12, and 13 is a nozzle body 12. This ejection hole 13 is disposed at the tip of the holder, and by operating the switching lever 12, the ejection hole 13 is displaced on an arcuate trajectory as shown in FIG. That is, in FIG. 4, a is at rest, b
is the position of the nozzle for the anus, and c is the position of the nozzle for the bidet. Although the water supply means is not shown, it is disposed within the main body case 11, communicates with the nozzle body 10, and has a valve mechanism, with the ejection holes located at positions b and c.
When in position, the opening operation occurs. In this conventional example, it is relatively easy to recognize the state of the ejection pattern, but each time it is used, a separate operation is required for each purpose, so the operation is complicated, and the configuration is also complicated, making it expensive. It had

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a sanitary washing device in which the switching operation of the jetting pattern of washing water is extremely simple.

The basic structure of the present invention for achieving the above object includes a control circuit that returns the jetting pattern to the steady mode jetting pattern by an off signal of the seating detection means that detects when the user is sitting on the toilet seat. It was established.

With the above configuration, when the user leaves the toilet seat after washing, the present invention returns to the frequently used steady mode spray pattern, so when the user cleans using the less frequently used spray pattern, Therefore, it is possible to obtain a sanitary cleaning device that is extremely easy to operate for the user and does not require the user to have to worry about recognizing the spray pattern each time it is used. It is possible.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 5 shows a nozzle body of a toilet seat according to an embodiment of the present invention, and FIG. 6 shows a cross-sectional view taken along the line A-A' in FIG. This nozzle body 14 is a nozzle body that spouts cleaning water in a plurality of jetting patterns to the cleaning section.

First, when the user sits on the toilet seat, the micro switch 23 is turned on, and then when the user presses the push button switch 24 in the switching operation to turn it on. When the relay 25 is energized, its self-holding contact is turned on to carry out self-holding, and the electromagnetic coil 18 is energized. In this case, when the push button switch 24 is released, it will automatically return to its original state and turn off. and electromagnetic coil 1
8 causes the permanent magnet 19 to repel and push up the movable element 20 against the spring force of the spring 21. Next, when the water supply means is operated, the cleaning water passes through the hole 20a of the movable element 20 and is ejected from the nozzle hole 16 in a slightly constricted jet stream.

In this state, when the user leaves the toilet seat, the micro switch 23 turns off and the relay 2
5 is cut off, its self-holding contact 26
is turned off, the energization of the electromagnetic coil 18 is also released. As a result, the movable element 20 automatically returns to its original state, that is, the steady mode shown in FIG. 5, by the spring force of the spring 21.

FIG. 8 shows a state in which the nozzle body 14 of the present invention is arranged at a rear position of the toilet seat 28, and FIG. 9 shows a seating detection means, where 29 shows the toilet seat 28 supported by a floating shaft.
The rotating shaft 23 is a micro switch.

Fig. 10 shows another embodiment of the present invention, and Fig. 11 shows a steady mode ejection state.
Reference numeral 30 denotes a cylindrical nozzle case, which has an opening 31 at its tip and a vertical groove 32 formed on its inner surface. Reference numeral 33 denotes a middle cylinder, and this middle cylinder 33 is provided so as to loosely fit into the groove 32 of the nozzle case 30 and protrude forward. 34 is a spring for returning the middle cylinder 33 to the state shown in FIG. 10. Reference numeral 35 denotes a nozzle body, and this nozzle body 35 is rotatably provided by loosely fitting into the middle cylinder 33, and is attached to the nozzle case 3 together with the middle cylinder 33.
It is configured to be able to protrude outward from the opening 31 of 0. 36 is a switching knob, and this switching knob 3
6 is rotatably attached to the nozzle case 30 via a water sealing ring 37, and a locking portion 38
is formed.

39 is a push-type electromagnetic solenoid, and the tip of a plunger 40 engages with a locking portion 38.
41 is a torsion spring for returning the switching knob 36 to the steady mode state, that is, the state shown in FIG. 12a. 42 is the switching knob 36
This reversing pin 42 is engaged with a groove 43 formed in the nozzle body 35,
The above-mentioned 38, 39, 40, and 41 constitute a return means. Reference numeral 44 indicates a jet outlet hole formed in the nozzle body 35, 45 indicates a shower outlet outlet hole located on the opposite side of the nozzle body 35, and 46 indicates a shower outlet hole provided in the nozzle body 35. This opening 46 corresponds to the ejection holes 44 and 45. Further, an electric circuit connected to the electromagnetic coil 47 of the electromagnetic solenoid 39 is connected to a DC power source 48.
and a micro switch 49, and the micro switch 49 is arranged under the toilet seat as a seating detection means. 50 is a water inlet of the nozzle case 30 that communicates with the water supply means.

Next, the operation in the above configuration will be explained.
First, when a user sits on the toilet seat, the micro switch 49 is turned on and the electromagnetic solenoid 39 is energized. Next, when the water supply means is operated, the pressure of the cleaning water supplied from the water inlet 50 causes the nozzle body 35 and the middle cylinder 33 to move toward the nozzle case 30, as shown in FIG.
The cleaning water that protrudes outward from the opening 31 and passes through the inside of the middle cylinder 33 is passed through the jet hole 4 for jet flow.
4 through an opening 46 to obtain a jet stream.

If the water supply means is stopped in this state, the spring force of the spring 34 causes the middle cylinder 33 and the nozzle body 35 to return to the state shown in FIG. 10. When the state shown in FIG. 10 is set to the steady mode, the engagement state between the switching knob 36 and the tip of the plunger 40 of the electromagnetic solenoid 39 is as shown in FIG. 12a.

When changing the flushing water spout pattern, the user first sits on the toilet seat and excites the electromagnetic solenoid 39 using the micro switch 49, and then turns the switching knob 36 counterclockwise from the state shown in FIG. 12a.
When rotated 180 degrees, as shown in Figure 12b,
Since the tip of the plunger 40 of the electromagnetic solenoid 39 fits into the locking groove 38a of the locking portion 38, the switching knob 36 is locked in that position. At this time, the reversing pin 42 also rotates counterclockwise as the switching knob 36 rotates, causing the nozzle body 35 to rotate. When the reversing pin 42 comes to the position shown in FIG. 12b, the nozzle body 35 also rotates 180 degrees counterclockwise from the state shown in FIG. As shown in FIG. 13, it faces the shower outlet 45. When the water supply means is operated in this state, the pressure of the washing water supplied from the water inlet 50 will cause
As shown in FIG. 14, the nozzle body 35, the middle cylinder 33
protrudes outward from the opening 31 of the nozzle case 30, and the cleaning water that has passed through the middle cylinder 33 is jetted out from the shower jet hole 45 through the opening 46 to obtain a shower flow.

When the user leaves the toilet seat after cleaning, the micro switch 49 is turned off and the electromagnetic solenoid 39 is de-energized.
The plunger 40 enters the electromagnetic solenoid 39 and comes out of the locking groove 38 of the locking portion 38.
This releases the lock of the switching knob 36, so the switching knob 36 is rotated by the torsion spring 41.
It rotates clockwise due to the spring force of , and returns to the state shown in FIG. 12a. At this time, the reversing pin 42 also rotates clockwise as the switching knob 36 rotates, causing the nozzle body 35 to rotate. and reversal pin 4
2 comes to the position shown in FIG. 12a, the nozzle body 35 also rotates 180 degrees clockwise from the state shown in FIG. As shown in FIG. 3, it faces a jet hole 44 for jet flow. That is, when the user leaves the toilet seat after washing, the nozzle body 3
5 automatically returns to the steady mode shown in FIG.

Note that FIGS. 15 and 16 are a front view and a side view showing the nozzle body 51 in the embodiment shown in FIGS. 10 to 14 above, which is installed below the side of the toilet seat 52. In addition, in each of the above embodiments, a configuration was shown in which a single nozzle body discharges cleaning water with multiple jetting patterns, but even if a plurality of nozzle bodies with a single jetting pattern are provided, the overall device The nozzle body has a plurality of ejection patterns, and the number of nozzle bodies is not limited.

As described above, according to the present invention, a restoring means is provided for returning the jetting pattern to the jetting pattern in the steady mode in response to the off signal of the seating detection means for detecting that the user is sitting on the toilet seat. When the user leaves the toilet seat after washing, the spray pattern returns to the frequently used steady mode, so the user only needs to perform a switching operation when flushing with the less frequently used spray pattern. As a result, it is possible to obtain a sanitary cleaning device that is extremely easy to operate for the user and does not require the user to have to worry about recognizing the spray pattern each time it is used.
