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 6 is a toilet 2 page lid. 6 is a nozzle body, this nozzle body 6 is supported by the main body case 3, and the jet hole 7a provided at the tip of the nozzle body 6 is reversed by operation of the switching lever 8 to become the jet hole 7b.
Replaced with 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.In this case, the flushing water spout pattern can be arbitrarily switched and selected depending on the purpose of use for the anus and bidet. There is a need to. This switching of the jetting pattern is performed by combining the jetting direction of water for cleaning, the diameter or number of pores forming the jetting holes, etc., and obtaining the optimum cleaning effect according to 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 the jetting hole 7a
, 7b and the switching lever 8 are located in the actual position of the toilet bowl 1 to avoid the adhesion of filth when emptying the toilet, so it is difficult to recognize the switching state. There was a problem in that the water supply means was inadvertently energized and the excess water was wetted.

3 and 4 show another conventional example, where 9 is a toilet seat, 1o 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 1.
This jet hole 13 is disposed at the tip of the rotor 2, and by operating the switching lever 12, the jet 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 ejection hole for the anus, and (C1 is the position of the bidet nozzle. Although the water supply means is not shown, the main body case 11
The nozzle body 1o is disposed within the nozzle body 1o and has a pulp mechanism, and the ejection holes are located at the (b) position and (C).
When in the 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 to achieve the above object is to provide 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 is something.

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 recognition of the spray pattern each time it is used. It is.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 6 shows a nozzle body of a toilet seat according to an embodiment of the present invention, and FIG.
The figure shows a cross-sectional view taken along the line A', and 14 is a nozzle body that sprays 5 pages of washing water in a plurality of spray patterns onto the washing section of a user seated on the toilet seat.This nozzle body 14 is constructed as follows. ing. That is, 15 is a cylinder with a nozzle hole 16 bored at its tip;
A hollow iron core 17 is fixed inside, and an electromagnetic coil 18 is fixed to the outer periphery. 19 is cylinder 15
It is a permanent magnet that is inscribed in the magnet and is slidably provided.

2o has a hole 20a in the center and a groove 20a on the outer periphery.
This movable element 2o is housed inside a cylinder 16 so that it can slide freely, and a spring 21 is interposed between the inner wall of the cylinder 16 and the movable element 20, and the spring 21 causes the permanent magnet 19 to is biased so that it is always in contact with the iron core 17.

Further, the control circuit 22 connected to the electromagnetic coil 18 includes a microswitch 23 used as a seating detection means, an automatic return type push button switch 24 for switching operation, a relay 25, and a self-holding contact of this relay 26. 26 and a DC power supply 27, and these are arranged inside the main body case.

At the water inlet of the 15aid cylinder 15, this water inlet 6:: RO 15a is a water supply means (
(not shown), and when this water supply means is operated, the cleaning water passes through the central hole 20a of the mover 20 and the surrounding groove 20b, and is jetted out from the nozzle hole 16 in a slightly diffused shower flow. do.

This jetting pattern is in a steady mode, and even if the microswitch 23 is turned on when the user sits on the toilet seat, the electromagnetic coil 18 is not energized because the push button switch 24 for switching operation is not pressed. As a result, the mover 2o remains stationary.

FIG. 7 shows a cross-sectional view of the state in which the ejection pattern is switched. First, when the user sits on the toilet seat, the microswitch 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. Then, due to the biasing of the electromagnetic coil 18, the permanent magnet 19 repulses and pushes up the movable element 2o against the spring force of the 7-page spring 21. Next, when the water supply means is operated, the cleaning water passes through the hole 20a of the movable element 2o and is ejected from the nozzle hole 16 in a slightly constricted jet stream.

When the user leaves the toilet seat in this state, the microswitch 23 is turned off, the power to the relay 26 is cut off, and the self-holding contact 26 is turned off, so that the electromagnetic coil 18 is also energized. It will be canceled. As a result, the movable element 2o automatically returns to its original state, that is, the steady mode shown in FIG. 6, by the spring force of the spring 21.

FIG. 8 shows the nozzle body 14 of the present invention arranged at the rear position of the toilet seat 28, and FIG. 9 shows the seat detection means, where 29 is the rotating shaft of the floating toilet seat 28, and 23 is a diagram showing the seating detection means. It's a micro switch.

FIG. 10 shows another embodiment of the present invention, and FIG. 11 shows a steady mode jetting state. 3o is a cylindrical nozzle case, and the nozzle case 30 has an opening 31 at its tip. and has a vertical groove 32 formed on its inner surface. 33 is a middle cylinder, and this middle cylinder 33 is connected to the nozzle case 30.
(The D groove 32VC is loosely fitted and is provided so as to freely protrude forward. 34 is a spring for returning the middle cylinder 33 to the state shown in FIG. 10. 35 is a nozzle body, and this nozzle body 36 is It is rotatably provided in the middle cylinder 33 with a loose fit, and is configured to be able to protrude outward from the opening 31 of the nozzle case 3° together with the middle cylinder 33.

Reference numeral 36 denotes a switching knob, which is rotatably attached to the nozzle case 30 via a water sealing ring 37, and forms a locking portion 38.

be. Reference numeral 42 denotes a reversing pin protruding inwardly from the switching knob 36, and this reversing pin 42 engages with a groove 43 formed in the nozzle body 35. Reference numeral 44 indicates an ejection hole for jet flow formed in the nozzle body 35; 46 indicates an ejection hole for shower flow, located on the opposite side of the ejection hole 44 and provided in the bottom of the nozzle body 369;
This opening 46 is formed in the spout hole 44.
．． It corresponds to 45. The electric circuit connected to the electromagnetic coil 4γ of the electromagnetic solenoid 39 is composed of a DC power source 48 and a microswitch 49, and the microswitch 49 is placed under the toilet seat as a seating detection means. 50
is a water inlet of the nozzle case 3o that communicates with the water supply means.

Next, the operation in the above configuration will be explained.

First, when the user sits on the toilet seat, the micro switch 4
9 turns on and excites the electromagnetic solenoid 39. Next, when the water supply means is operated, the pressure of the washing water supplied from the water inlet 5o causes the nozzle body 36, the middle cylinder 3
3 protrudes outward from an opening 31 of the nozzle case 3°, and the cleaning water that has passed through the middle cylinder 33 is ejected from a jet-flow ejection hole 44 through an opening 46 to obtain a jet flow.

In this state, if the water supply means is stopped, the spring force of the spring 34 causes the middle cylinder 33 and the nozzle body 10 to return to the state shown in FIG. Then, when the state shown in Fig. 10 is set to the steady mode, the switching t knob 3
6 and the tip of the plunger 4o of the electromagnetic solenoid 39 are engaged as shown in FIG. 12 (-).

To change the flushing water spout pattern, the user first sits on the toilet seat and excites the electromagnetic solenoid 39 using the microswitch 49, and then turns the switching knob 36 as shown in FIG.
-) When it is rotated 180 degrees counterclockwise from the state shown in FIG. 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. 12(b), the nozzle body 35 also rotates 180 degrees counterclockwise from the state shown in FIG. As shown in FIG. 13, the portion 46 is 11' opposite to the shower nozzle 45. When the water supply means is operated in this state, the pressure of the cleaning water supplied from the water inlet 6o causes the nozzle body 35 and the middle cylinder 33 to protrude outward from the opening 31 of the nozzle case 30, as shown in FIG. The cleaning water that has passed through the middle cylinder 33 flows from the shower outlet 45 to the opening 46.
Squirt through and get a shower flow.

During cleaning, when the user leaves the toilet seat,
Since the microswitch 49 is turned off and the electromagnetic solenoid 39 is deenergized, the plunger 4o enters the electromagnetic solenoid 39 and comes out of the locking groove 38 of the locking portion 38.

This unlocks the switching knob 36, so that the switching knob 36 is rotated clockwise by the spring force of the torsion spring 41 and returns to the state shown in FIG. 12(a). At this time, the reversing pin 42 also rotates clockwise 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. 12(,), the nozzle body 35 also changes from the state shown in FIG.
As a result, the middle cylinder 33
As shown in FIG. 10, the opening 46 faces the jet nozzle 44. That is, when the user leaves the toilet seat after washing, the nozzle body 35
The system automatically returns to the steady mode shown in the figure.

Note that Figures 15 and 16 are the same as Figures 10 to 14 above.
5 is a front view and a side view showing a state in which the nozzle main body 51 in the illustrated embodiment is installed below the side of a toilet seat 52. FIG.

As described above, according to the present invention, a control circuit is provided which returns the jetting pattern to the jetting pattern in the steady mode based on the off signal of the seating detection means that detects whether the user is sitting on the toilet seat, and the cleaning is completed. When the user moves away from the toilet seat, 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. It is thus possible to obtain a sanitary cleaning device which is extremely easy for the user to operate and which does not cause the user to have to worry about recognizing the spray pattern each time it is used.
