Description

[Detailed description of the invention] Industry - Application field of J2 The present invention relates to a flushing device for a flush toilet.

Structure of the conventional example and its problems The most common conventional toilet flushing device is installed in the wall of the toilet and is installed through the wall of the toilet in order to open the valve provided at the bottom of the toilet. It has a configuration that allows water to flow into the toilet bowl by driving it with a manual lever.
Because the water pressure in the cistern is applied to the valve, a considerable amount of force is required to operate the manual lever, making it difficult for children and the elderly with weak strength to use, and at the same time, many people touch the manual lever after defecating. However, if you forget to operate the manual lever, washing with water is not performed, which causes odors to be emitted, which is a hygiene problem.

Therefore, as a solution to these drawbacks, Figure 1~
As shown in FIG. 3, a configuration has also been considered in which the toilet seat is automatically flushed by detecting that the person has stood up from the toilet seat.

Figure 1 shows its configuration. 1 is a toilet bowl, 2 is a toilet seat, 3 is a cistern that stores water for flushing the inside of the toilet bowl 1, 4 is a valve provided at the bottom of the cistern 3, and 5 is one end of the valve 4. 6 is an arm connected to the other end of the chain 6, 7 is a penetrating shaft provided through the wall of the distern 3 and one end is connected to the arm 6, 8 is the outer wall of the distern 3 A rotary solenoid 9 which is installed in and rotates the penetrating shaft 7 from the outside of the toilet 3 to rotate the arm 6 and pull up the chain 5 to open the valve 4 and release water into the toilet bowl 1.
Manual 1 also performs water washing by manually rotating the through shaft 7.
The collar 110 is the electric wire, and 11 is the toilet seat 2. When no one is sitting, the VC presses the rear of the toilet seat 2. It is turned off in the double digit state, and when a person sits on the toilet seat 2, its weight [therefore, it is turned on as a seat detection means. A microswitch 12 is an energizing means for energizing the rotary solenoid 8 in response to an off signal from the microswitch 11; 13 is a microswitch located at the rear of the toilet seat 2;

FIG. 3 is a circuit diagram of the energizing means 12 in the conventional example, where 42 is a power source, 43 is a capacitor forming a timer (111), and 44 is a charging resistor for the capacitor 43.

45 and 46 are resistors for base thread potential, 47 is a discharge resistor of the capacitor 43, 48 is a comparator, 49 is a pull-up resistor, 50 is a current limiting resistor, and 51 is a capacitor whose potential is low.
to Hi [one yacht multi which generates a short time pulse (about 0.5 seconds) from the output f when reversed, 52 is the base resistance, 5 3 t6), run disk, 64 is the reverse of the rotary solenoid 8 Raising force absorption +■] is a diode.

In the configuration shown in FIGS. 1 to 3 above, when a user sits on the toilet seat 2, the microswitch 11 is turned on and the capacitor 4
3 is rapidly discharged, and the potential of the output cap of the comparator 48 and the input cap of the wrinkle shot multi 61 is set to Low. Therefore, one shot, the output fIti of the Nodo Multi 51
The transistor 53 remains OFF, maintaining the low level.

When the user finishes using the toilet and stands up from the toilet seat 2 for a certain period of time, for example 3 seconds, the potential of the capacitor 43 increases and the output of the comparator 48 becomes Hi [inverted. At that moment, a short pulse is generated from the output f of the one-shot multi 61, energizing the instantaneous rotary solenoid 8, rotating the through shaft 7, opening the valve 4, and automatically performing water washing. If a situation arises in which the rotary renoid 8 cannot be energized due to a power outage or a circuit failure in the energizing means 12, the manual reno-9 is operated to perform water washing.

In the above configuration, when the user finishes using the toilet and stands up from the toilet seat.
Since the toilet bowl is flushed automatically when the toilet is empty, even the elderly and children can flush the toilet bowl without bothering the user's hands. It is clean because it does not emit odors when forgotten, and therefore it has a configuration that eliminates most of the drawbacks of the conventional method, but in actual use tests with many people, a new problem was posed. The reason for this is that the flushing process is not limited to just once when rising from the toilet seat, but some users may flush multiple times.
] is used while washing with water to muffle the sound of use,
If you are concerned about the odor while using the toilet, you may want to flush it with water even during use. However, if you need to flush the toilet while sitting on the toilet seat, you should bend over from the toilet seat and flush the dust. Either you have to operate the detection means or you have to operate the manual switch at the back - 9, which is useful for elderly people and children who have weak operating power, users who can't stand sitting on their knees, and children who can't reach their feet at their original size. The configuration described in item 1 had a drawback that it could not fully demonstrate its features.

OBJECT OF THE INVENTION The present invention solves these conventional problems, and it is possible to flush the toilet automatically when the user stands up from the toilet seat, and to flush the toilet easily while sitting down by operating a switch at hand even when the toilet seat is in use. The purpose of the present invention is to provide a toilet flushing device that can flush the toilet bowl.

Structure of the Invention In order to achieve this object, the present invention provides a switch means operated by a person sitting on the toilet seat, and the energizing means is configured so that the rotary solenoid can also be energized by a signal from the switch means. 0 Description of Embodiment FIG. 4 shows an embodiment of the toilet flushing device of the present invention.

C, which will be explained using FIG.

FIG. 4 is a block diagram of an embodiment of the toilet flushing device of the present invention, and the difference from the conventional example shown in FIG.
3 is provided with a switch means 66 that can be operated by the user while sitting on the toilet seat 2.

FIG. 6 is a circuit diagram of the biasing means 12 in the same embodiment, and the difference from the conventional example shown in FIG. In the above configuration, the operation of automatically flushing while standing up from the toilet seat 2 is the same as the conventional example, so the explanation will be omitted. When the switch is turned on/off, the switch means 66
Turn on manually. At this time, since the microswitch 11 is in a low state, the output of the conoperator 48 is Low, but as the switch means 55 is turned on, the input potential of the one-shot multi 61 immediately becomes Hl, and therefore a pulse is output from the output φ. The rotary solenoid 8 can be energized to perform water washing.

In addition, although a microswitch was used as the dust detection means in the example, other detection means such as a pressure sensor that emits a signal by applying body weight or detection using the resistance of the surface of the skin of the buttocks can also be used. Although a rotary solenoid was used in the embodiment as the electromagnetic drive means, it is obvious that other types of solenoids or motors can be used to perform similar operations. ” The present invention is not limited to the first embodiment.

Effects of the Invention As described above, the toilet flushing device of the present invention includes a means for discharging the water inside the flush toilet bowl into the toilet bowl, and a means for discharging the water inside the flush toilet bowl into the toilet bowl, and a dust collector for detecting that a person has sat on the toilet seat installed in the toilet bowl. comprising a detection means, a switch operated by a person sitting on the toilet seat, and an energizing means for energizing the discharge means by a signal from the dust detection means or the switch;
When you stand up from the toilet seat after using the toilet seat, the energizing means activates the discharge means (7) according to the signal from the seat inspection means (7) and automatically flushes the water, and if you operate the switch means while the toilet seat is in use, Since flushing can be performed in the same manner as described above by a signal, when the user finishes using the toilet seat, all they have to do is stand up from the toilet seat, and regardless of whether they are elderly or children, the toilet can be flushed reliably without bothering their hands, making it easy to use. Not only is it clean, but even when you are sitting on the toilet seat, you can flush the toilet at any time by simply operating the switch, so for example, you can use it while flushing to eliminate the sound of use. It has the versatility to satisfy women and users who wash the product many times with water because of the odor during use.
